T1 - The PEPSI exoplanet transit survey (PETS) I: Investigating the presence of a silicate atmosphere on the super-earth 55 Cnc e JF - Monthly notices of the Royal Astronomical Society N2 - The study of exoplanets and especially their atmospheres can reveal key insights on their evolution by identifying specific atmospheric species. For such atmospheric investigations, high-resolution transmission spectroscopy has shown great success, especially for Jupiter-type planets. Towards the atmospheric characterization of smaller planets, the super-Earth exoplanet 55 Cnc e is one of the most promising terrestrial exoplanets studied to date. Here, we present a high-resolution spectroscopic transit observation of this planet, acquired with the PEPSI instrument at the Large Binocular Telescope. Assuming the presence of Earth-like crust species on the surface of 55 Cnc e, from which a possible silicate-vapor atmosphere could have originated, we search in its transmission spectrum for absorption of various atomic and ionized species such as Fe , Fe (+), Ca , Ca (+), Mg, and K , among others. Not finding absorption for any of the investigated species, we are able to set absorption limits with a median value of 1.9 x R-P. In conclusion, we do not find evidence of a widely extended silicate envelope on this super-Earth reaching several planetary radii.

JF - Climatic change N2 - To better understand how climate change might influence global canola production, scientists from six countries have completed the first inter-comparison of eight crop models for simulating growth and seed yield of canola, based on experimental data from six sites across five countries. A sensitivity analysis was conducted with a combination of five levels of atmospheric CO2 concentrations, seven temperature changes, five precipitation changes, together with five nitrogen application rates. Our results were in several aspects different from those of previous model inter-comparison studies for wheat, maize, rice, and potato crops. A partial model calibration only on phenology led to very poor simulation of aboveground biomass and seed yield of canola, even from the ensemble median or mean. A full calibration with additional data of leaf area index, biomass, and yield from one treatment at each site reduced simulation error of seed yield from 43.8 to 18.0%, but the uncertainty in simulation results remained large. Such calibration (with data from one treatment) was not able to constrain model parameters to reduce simulation uncertainty across the wide range of environments. Using a multi-model ensemble mean or median reduced the uncertainty of yield simulations, but the simulation error remained much larger than observation errors, indicating no guarantee that the ensemble mean/median would predict the correct responses. Using multi-model ensemble median, canola yield was projected to decline with rising temperature (2.5-5.7% per degrees C), but to increase with increasing CO2 concentration (4.6-8.3% per 100-ppm), rainfall (2.1-6.1% per 10% increase), and nitrogen rates (1.3-6.0% per 10% increase) depending on locations. Due to the large uncertainty, these results need to be treated with caution. We further discuss the need to collect new data to improve modelling of several key physiological processes of canola for increased confidence in future climate impact assessments.

However, forests experience massive increases in stresses in their ecological and socioeconomic environments, threatening forest ecosystem services supply. Alleviating those stresses is hampered by conflicting and disconnected governance arrangements, competing interests and claims, and rapid changes in technology and social demands. Identifying which stresses threaten forest ecosystem services supply and which factors hamper their alleviation requires stakeholders' perceptions. Stakeholder-oriented stress tests for the supply of forest ecosystem services are therefore necessary but are not yet available. This perspective presents a roadmap to develop a stress test tailored to multiple stakeholders' needs and demands across spatial scales. We provide the Cascade and Resilience Rosetta, with accompanying performance- and resilience indicators, as tools to facilitate development of the stress test. The application of the stress test will facilitate the transition toward a bio-based economy in which healthy and diverse forests provide sustainable and resilient ecosystem services.

In this paper, we characterise the gas in the vicinity of Milky Way and Andromeda analogues in the hestia (High resolution Environmental Simulations of The Immediate Area) suite of constrained Local Group (LG) simulations. The hestia suite comprise of a set of three high-resolution arepo-based simulations of the LG, run using the Auriga galaxy formation model. For this paper, we focus only on the z = 0 simulation datasets and generate mock skymaps along with a power spectrum analysis to show that the distributions of ions tracing low-temperature gas (H i and Si iii) are more clumpy in comparison to warmer gas tracers (O vi, O vii and O viii). We compare to the spectroscopic CGM observations of M31 and low-redshift galaxies. hestia under-produces the column densities of the M31 observations, but the simulations are consistent with the observations of low-redshift galaxies. A possible explanation for these findings is that the spectroscopic observations of M31 are contaminated by gas residing in the CGM of the Milky Way.

There remain considerable gaps in our knowledge of marine mammal bioenergetics, which hinder the application of bioenergetic studies to inform policy decisions. We conducted a priority-setting exercise to identify high-priority unanswered questions in marine mammal bioenergetics, with an emphasis on questions relevant to conservation and management. Electronic communication and a virtual workshop were used to solicit and collate potential research questions from the marine mammal bioenergetic community. From a final list of 39 questions, 11 were identified as 'key'questions because they received votes from at least 50% of survey participants. Key questions included those related to energy intake (prey landscapes, exposure to human activities) and expenditure (field metabolic rate, exposure to human activities, lactation, time-activity budgets), energy allocation priorities, metrics of body condition and relationships with survival and reproductive success and extrapolation of data from one species to another. Existing tools to address key questions include labelled water, animal-borne sensors, mark-resight data from long-term research programs, environmental DNA and unmanned vehicles. Further validation of existing approaches and development of new methodologies are needed to comprehensively address some key questions, particularly for cetaceans. The identification of these key questions can provide a guiding framework to set research priorities, which ultimately may yield more accurate information to inform policies and better conserve marine mammal populations.

T1 - Mit der Bibel in die Moderne BT - Entstehung und Entwicklung jüdischer Kinderbibeln T3 - Studia Judaica N2 - Gegen Ende des 18. Jahrhunderts entwickelte sich im Zuge der jüdischen Aufklärung erstmals eine explizit an ein kindliches Lesepublikum gerichtete Literatur. Den jüdischen Aufklärern galt die verstärkte Auseinandersetzung mit der Hebräischen Bibel als Möglichkeit, an jüdische Traditionen anzuknüpfen, gleichzeitig aber auch neuen Vorstellungen und Erwartungen, die von jüdischer und nichtjüdischer Seite an ein modernes Judentum gestellt wurden, gerecht zu werden. Daher gehörten Kinderbibeln, die eine Auswahl an oftmals überarbeiteten Texten der Hebräischen Bibel bieten, zu den ersten solcher Werke, die veröffentlicht wurden. Im 19. Und dem frühen 20. Jahrhundert entwickelte sich die Jüdische Kinderbibel zur erfolgreichsten Gattung jüdisch-religiöser Bildungsmedien. Auswahl und Bearbeitung der Texte folgten dabei bestimmten pädagogischen, philosophischen und religiösen Anliegen und waren auf ein konkretes Lesepublikum abgestimmt. Die vorliegende Studie untersucht diese Werke als Quelle gesellschaftlicher und religiöser Transfer-, Transformations- und Innovationsprozesse ihrer Zeit. Dabei wird zunächst der historische Kontext der Entstehungszeit und anschließend die Entwicklung der Gattung bis in das 21. Jahrhundert nachgezeichnet und mit eingehenden Textanalysen illustriert. Grundlage und Leitlinien der Untersuchung bilden die Analyse verschiedener Bearbeitungsstrategien in Bezug auf den biblischen Text. Neben der religionshistorischen Perspektive werden auch literatur-, sprach- und kulturwissenschaftliche Fragestellungen auf die Gattung Jüdische Kinderbibel angewandt.

However, a portfolio of CDR options is necessary to reduce risks and potential negative side effects. Despite a large theoretical potential, ocean-based CDR such as ocean alkalinity enhancement (OAE) has been omitted in climate change mitigation scenarios so far. In this study, we provide a techno-economic assessment of large-scale OAE using hydrated lime ('ocean liming'). We address key uncertainties that determine the overall cost of ocean liming (OL) such as the CO2 uptake efficiency per unit of material, distribution strategies avoiding carbonate precipitation which would compromise efficiency, and technology availability (e.g., solar calciners). We find that at economic costs of 130–295 $/tCO2 net-removed, ocean liming could be a competitive CDR option which could make a significant contribution towards the Paris climate target. As the techno-economic assessment identified no showstoppers, we argue for more research on ecosystem impacts, governance, monitoring, reporting, and verification, and technology development and assessment to determine whether ocean liming and other OAE should be considered as part of a broader CDR portfolio.

Der Analysezeitraum umfasst 15 Jahre. Unser Datensatz beinhaltet Informationen zu 428 Autor:innen mit insgesamt 627 zwischen den Jahren 2005 und 2020 nominierten Büchern und 2.469 Rezensionen zu diesen Büchern. Der Datensatz wurde mittels mehrerer Methoden (z. B. Web-Scraping, Hand-Kodierung, Expert:innenbewertungen) aus verschiedenen Quellen (z. B. Web-Daten, Bibliothekskataloge, Expert:innenbewertungen) zusammengestellt. Auf diese Weise können wir unter anderem zeigen, dass für alle untersuchten Preise überwiegend deutsche Muttersprachler:innen mit gut rezensierten Büchern aus renommierten Verlagen nominiert werden und die Preise gewinnen. N2 - We undertake a comparative study of the nominees and winners of seven book awards in German-speaking countries that use a pre-published longlist and/or shortlist. To do this, we compare the awards in terms of the authors’ socio-demographic factors (gender, age, and native language), their prominence at the time of nomination (views on Wikipedia), the number of the authors’ previous nominations for the same book award, the ›quality‹ of the winning books (number of reviews of the nominated book, positive or negative assessment in reviews, and the reviewers’ unanimity about it), the reputation of the publishers, and the gender composition of the juries. The time period of analysis is 15 years. Our dataset includes information on 428 authors with a total of 627 nominated books and 2,469 reviews of these books. The dataset was compiled using several methods (e.g., web scraping, hand coding, expert reviews) from different sources (e.g., web data, library catalogs, expert reviews). This allows us to show, among other things, that for all the prizes studied, mostly German native speakers with well-reviewed books from reputable publishers are nominated and win the prizes.

Botanical gardens are ideal places in which to investigate large numbers of species growing under common climate conditions. We ask whether interspecific variation in plant phenology is influenced by differences in functional traits. We recorded onset, end, duration and intensity of initial growth, leafing out, leaf senescence, flowering and fruiting for 212 species across five botanical gardens in Germany. We measured functional traits, including plant height, absolute and specific leaf area, leaf dry matter content, leaf carbon and nitrogen content and seed mass and accounted for species' relatedness. Closely related species showed greater similarities in timing of phenological events than expected by chance, but species' traits had a high degree of explanatory power, pointing to paramount importance of species' life-history strategies. Taller plants showed later timing of initial growth, and flowered, fruited and underwent leaf senescence later. Large-leaved species had shorter flowering and fruiting durations. Taller, large-leaved species differ in their phenology and are more competitive than smaller, small-leaved species. We assume climate warming will change plant communities' competitive hierarchies with consequences for biodiversity.

Here, the expertise from fifteen laboratories is combined to quantitatively model the current-voltage characteristics of a solar cell from such measurements. To this end, the impact of measurement conditions, alternate interpretations, and experimental inter-laboratory variations are discussed using a (Cs,FA,MA)Pb(I,Br)(3) halide perovskite thin-film as a case study. At 1 sun equivalent excitation, neither transport nor recombination is significantly affected by exciton formation or trapping. Terahertz, microwave, and photoluminescence transients for the neat material yield consistent effective lifetimes implying a resistance-free JV-curve with a potential power conversion efficiency of 24.6 %. For grainsizes above approximate to 20 nm, intra-grain charge transport is characterized by terahertz sum mobilities of approximate to 32 cm(2) V-1 s(-1). Drift-diffusion simulations indicate that these intra-grain mobilities can slightly reduce the fill factor of perovskite solar cells to 0.82, in accordance with the best-realized devices in the literature. Beyond perovskites, this work can guide a highly predictive characterization of any emerging semiconductor for photovoltaic or photoelectrochemical energy conversion. A best practice for the interpretation of terahertz and microwave measurements on photovoltaic materials is presented.

Climate modelling for northern Europe indicates high summer temperatures and strong continentality. In eastern Europe, the scale of temperature variation and its influence on ecosystems is weakly recognised. Here, we present a multi-proxy reconstruction of YD conditions from Lake Gos ' ciaz (central Poland). The decadal-resolution analysis of its annually varved sediments indicates an initial decrease in Chironomidae-inferred mean July air temperature followed by steady warming. The pollen-inferred winter-to-summer temperature amplitude and annual precip-itation is highest at the Allerod/YD transition and the early YD (ca. 12.7-12.4 ky cal BP) and YD/Holocene (11.7-11.4 ka cal BP) transition. Temperature and precipitation were the main reasons for lake level fluctuations as reflected in the planktonic/littoral Cladocera ratio. The lake's diatom-inferred total phosphorus decreased with increasing summer temperature from about mid YD. Windy conditions in the early YD until ~12.3 ka cal BP caused water mixing and a short-lived/temporary increase in nutrient availability for phytoplankton. The Chironomidae-inferred summer temperature and pollen inferred summer temperature, winter temperature and annual precipitation herein are one of only a few in eastern Europe conducted with such high resolution.

Despite its high importance and long-standing efforts, the balance of administrative digitalization in Germany remains ambivalent. This study investigates the influencing factors on the implementation of digitalization projects in public administration, with a special focus on the role of top management support. This study focuses on three successful digitalization projects from the German Online Access Act (OZG) and analyzes, using problem-centered expert interviews, the influencing factors on the implementation of OZG projects and the role of management in this process. The analysis is theoretically grounded and based on the approach of bounded rationality and the economic theory of bureaucracy. The results suggest that the identified influencing factors affect the reusability and maturity level of administrative services differently and can be interpreted as consequences of bounded rationality in the human problem-solving process. Managers influence the bounded rationality of operational actors by implementing appropriate strategies in the support of their implementation tasks. This includes providing resources, contributing their expertise, making information accessible, changing decision-making pathways, and contributing to conflict resolution. The study provides valuable insights into actual management practices and derives recommendations for the implementation of public digitalization projects and the management of public administrations. This study makes an important contribution to understanding the influence of management in digitalization. It also underscores the need for further research in this area to better understand the practices and challenges of administrative digitalization and to effectively address them. N2 - Die Digitalisierung ist ein wesentlicher Bestandteil aktueller Verwaltungsreformen. Trotz der hohen Bedeutung und langjähriger Bemühungen bleibt die Bilanz der Verwaltungsdigitalisierung in Deutschland ambivalent. Diese Studie konzentriert sich auf drei erfolgreiche Digitalisierungsvorhaben aus dem Onlinezugangsgesetz (OZG) und analysiert mittels problemzentrierter Expertenbefragung Einflussfaktoren auf die Umsetzung von OZG-Vorhaben und den Einfluss des Managements in diesem Prozess. Die Analyse erfolgt theoriegeleitet basierend auf dem Ansatz der begrenzten Rationalität und der ökonomischen Theorie der Bürokratie. Die Ergebnisse zeigen, dass anzunehmen ist, dass die identifizierten Einflussfaktoren unterschiedlich auf Nachnutzbarkeit und Reifegrad von Verwaltungsleistungen wirken und als Folgen begrenzter Rationalität im menschlichen Problemlösungsprozess interpretiert werden können. Managerinnen unterstützen die operativen Akteure bei der Umsetzung, indem sie deren begrenzte Rationalität mit geeigneten Strategien adressieren. Dazu können sie Ressourcen bereitstellen, mit ihrer Expertise unterstützen, Informationen zugänglich machen, Entscheidungswege verändern sowie zur Konfliktlösung beitragen. Die Studie bietet wertvolle Einblicke in die tatsächliche Managementpraxis und leitet daraus Empfehlungen für die Umsetzung öffentlicher Digitalisierungsvorhaben sowie für die Steuerung öffentlicher Verwaltungen ab. Diese Studie liefert einen wichtigen Beitrag zum Verständnis des Einflusses des Managements in der Verwaltungsdigitalisierung.

Verb-final languages have a reputation for a high amount of word order variability. However, that reputation amounts to an urban myth due to a lack of systematic investigation. This thesis provides such a systematic investigation by presenting original data from several verb-final languages with a focus on four Uralic ones: Estonian, Udmurt, Meadow Mari, and South Sámi. As with every urban myth, there is a kernel of truth in that many unrelated verb-final languages share a particular kind of word order variability, A-scrambling, in which the fronted elements do not receive a special information-structural role, such as topic or contrastive focus. That word order variability goes hand in hand with placing focussed phrases further to the right in the position directly in front of the verb. Variations on this pattern are exemplified by Uyghur, Standard Dargwa, Eastern Armenian, and three of the Uralic languages, Estonian, Udmurt, and Meadow Mari. So far for the kernel of truth, but the fourth Uralic language, South Sámi, is comparably rigid and does not feature this particular kind of word order variability. Further such comparably rigid, non-scrambling verb-final languages are Dutch, Afrikaans, Amharic, and Korean. In contrast to scrambling languages, non-scrambling languages feature obligatory subject movement, causing word order rigidity next to other typical EPP effects. The EPP is a defining feature of South Sámi clause structure in general. South Sámi exhibits a one-of-a-kind alternation between SOV and SAuxOV order that is captured by the assumption of the EPP and obligatory movement of auxiliaries but not lexical verbs. Other languages that allow for SAuxOV order either lack an alternation because the auxiliary is obligatorily present (Macro-Sudan SAuxOVX languages), or feature an alternation between SVO and SAuxOV (Kru languages; V2 with underlying OV as a fringe case). In the SVO–SAuxOV languages, both auxiliaries and lexical verbs move. Hence, South Sámi shows that the textbook difference between the VO languages English and French, whether verb movement is restricted to auxiliaries, also extends to OV languages. SAuxOV languages are an outlier among OV languages in general but are united by the presence of the EPP. Word order variability is not restricted to the preverbal field in verb-final languages, as most of them feature postverbal elements (PVE). PVE challenge the notion of verb-finality in a language. Strictly verb-final languages without any clause-internal PVE are rare. This thesis charts the first structural and descriptive typology of PVE. Verb-final languages vary in the categories they allow as PVE. Allowing for non-oblique PVE is a pivotal threshold: when non-oblique PVE are allowed, PVE can be used for information-structural effects. Many areally and genetically unrelated languages only allow for given PVE but differ in whether the PVE are contrastive. In those languages, verb-finality is not at stake since verb-medial orders are marked. In contrast, the Uralic languages Estonian and Udmurt allow for any PVE, including information focus. Verb-medial orders can be used in the same contexts as verb-final orders without semantic and pragmatic differences. As such, verb placement is subject to actual free variation. The underlying verb-finality of Estonian and Udmurt can only be inferred from a range of diagnostics indicating optional verb movement in both languages. In general, it is not possible to account for PVE with a uniform analysis: rightwards merge, leftward verb movement, and rightwards phrasal movement are required to capture the cross- and intralinguistic variation. Knowing that a language is verb-final does not allow one to draw conclusions about word order variability in that language. There are patterns of homogeneity, such as the word order variability driven by directly preverbal focus and the givenness of postverbal elements, but those are not brought about by verb-finality alone. Preverbal word order variability is restricted by the more abstract property of obligatory subject movement, whereas the determinant of postverbal word order variability has to be determined in the future. N2 - Diese Dissertation behandelt die Wortstellungsvariabilität verbfinaler Sprachen. Verbfinale Sprachen haben den Ruf, ein hohes Maß an Wortstellungsvariabilität aufzuweisen. Dieser Ruf beruht jedoch lediglich auf anekdotischen Befunden, da es einer systematischen Untersuchung eines solchen Zusammenhangs ermangelt. Die vorliegende Dissertation stellt eine solche systematische Untersuchung dar. Dafür werden neu erhobene Daten zu mehreren verbfinalen Sprachen präsentiert. Der Schwerpunkt liegt dabei auf vier uralischen Sprachen: Estnisch, Udmurtisch, Wiesenmari und Südsamisch. Der Ruf der Wortstellungsvariabilität erweist sich teils als wahr, da viele nicht miteinander verwandte, verbfinale Sprachen dieselbe Art Wortstellungsvariabilität teilen, das sogenannte A-Scrambling. A-Scrambling zeichnet sich gegenüber anderen Arten der Wortstellungsvariabilität dadurch aus, dass vorangestellten Elementen keine spezielle informationsstrukturelle Rolle wie Topic oder kontrastiver Fokus zukommt. A-Scrambling geht mit einem rechtsbefindlichen, unmittelbar präverbalen Fokus einher. Variationen des Musters aus A-Scrambling und präverbalem Fokus finden sich im Uigurischen, Standard-Dargwa, Ostarmenischen und in drei der uralischen Sprachen, nämlich Estnisch, Udmurtisch und Wiesenmari. Insofern bestätigt sich der Eindruck einer homogenen Wortstellungsvariabilität in verbfinalen Sprachen. Die vierte untersuchte uralische Sprache, Südsamisch, widerspricht diesem Eindruck jedoch. Südsamisch weist eine vergleichsweise feste Wortstellung auf trägt nicht die Kennzeichen von A-Scrambling. Darüberhinaus gibt es noch weitere, vergleichsweise starre, scramblinglose verbfinale Sprachen: Niederländisch, Afrikaans, Amharisch und Koreanisch. Im Gegensatz zu Sprachen mit A-Scrambling weisen scramblinglose Sprachen obligatorische Subjektbewegung (EPP) auf. Das EPP führt neben anderen typischen EPP-Effekten zu einer starren Wortstellung. Das EPP ist ein zentrales Merkmal der Satzstruktur im Südsamischen. Das Südsamische weist eine bislang nicht attestierte Alternation zwischen SOV- und SAuxOV-Stellung auf. Diese Alternation kann durch das Zusammenspiel von EPP und der obligatorischen Bewegung von Hilfsverben, nicht jedoch von lexikalischen Verben, erfasst werden. Andere Sprachen mit SAuxOV-Stellung weisen entweder keine systematische Alternation auf, weil das Hilfsverb obligatorisch vorhanden ist (Makro-Sudanische SAuxOVX-Sprachen), oder sie weisen eine Alternation zwischen SVO und SAuxOV auf (Kru-Sprachen; V2 mit zugrundeliegender Verbfinalität als Zweifelsfall). In den SVO–SAuxOV-Sprachen bewegen sich sowohl Hilfsverben als auch lexikalische Verben. Somit zeigt das Südsamische, dass eine sonst nur für VO-Sprachen bekannte parametrische Unterscheidung auch für OV-Sprachen gilt: der weithin bekannte Unterschied zwischen VO-Sprachen wie Englisch und Französisch, ob Verbbewegung auf Hilfsverben beschränkt ist. SAuxOV-Sprachen bilden insgesamt eine Ausnahme unter den OV-Sprachen, aber sie sind durch das Vorhandensein des EPP vereint. Wortstellungsvariabilität beschränkt sich in verbfinalen Sprachen nicht auf die präverbale Domäne. Die meisten verbfinalen Sprachen weisen postverbale Elemente (PVE) auf. PVE stellen den Status der Verbfinalität infrage. Strikt verbfinale Sprachen ohne jegliche satzinterne PVE sind jedoch selten. Diese Dissertation stellt zum ersten Mal eine strukturelle und deskriptive PVE-Typologie vor. Verbfinale Sprachen variieren in den Kategorien, die sie als PVE zulassen. Das Zulassen von nicht-oblike PVE ist eine entscheidende Schwelle: Wenn nicht-oblike PVE erlaubt sind, können PVE für informationsstrukturelle Effekte verwendet werden. Viele areal und genetisch nicht verwandte Sprachen erlauben nur gegebene PVE, unterscheiden sich jedoch darin, ob die PVE kontrastiv kontrastiv sein können. In diesen Sprachen steht die Verbfinalität nicht zur Debatte, da verbmediale Ordnungen nicht neutral sind. Im Gegensatz dazu erlauben die uralischen Sprachen Estnisch und Udmurtisch jede Art von PVE, einschließlich Informationsfoki. Verbmediale Stellungen können dort also in denselben Kontexten wie verbfinale Stellungen verwendet werden, ohne dass es zu semantischen und pragmatischen Unterschieden kommt. Hier kann also die Rede von tatsächlicher freier Variation in der Verbstellung sein. Die zugrunde liegende Verbfinalität des Estnischen und Udmurtischen kann nur mithilfe einer Reihe syntaktischer Tests abgeleitet werden, die auf optionale Verbbewegung in beiden Sprachen hinweisen. Insgesamt ist es nicht möglich, PVE mit einer einheitlichen Analyse zu erfassen: Merger nach rechts, linksgerichtete Verbbewegung und rechtsgerichtete Phrasenbewegung sind erforderlich, um die inter- und intralinguistische Variation zu erfassen. Zu wissen, dass eine Sprache verbfinal ist, erlaubt keine unfehlbaren Schlüsse über die Wortstellungsvariabilität in dieser Sprache. Es gibt Muster der Homogenität, wie die durch unmittelbar präverbalen Fokus und die Gegebenheit postverbaler Elemente getriebene Wortstellungsvariabilität. Diese Muster ergeben sich aber nicht allein aus der Verbfinalität. Die präverbale Wortstellungsvariabilität wird durch die abstraktere Eigenschaft der obligatorischen Subjektbewegung (EPP) bestimmt. Was die Möglichkeiten postverbaler Wortstellungsvariabilität bestimmt muss künftig ermittelt werden.

Connected, autonomous, shared, and electric (CASE) trends lead to new emerging players that threaten existing industrial-aged companies. To respond, incumbents need to bridge the gap between contrasting product architecture and organizational principles in the physical and digital realms. Over-the-air (OTA) technology, that enables seamless software updates and on-demand feature additions for customers, is an example of CASE-driven digital product innovation. Through an extensive longitudinal case study of an OTA initiative by an industrial- aged automaker, this dissertation explores how incumbents accomplish digital product innovation. Building on modularity, liminality, and the mirroring hypothesis, it presents a process model that explains the triggers, mechanisms, and outcomes of this process. In contrast to the literature, the findings emphasize the primacy of addressing product architecture challenges over organizational ones and highlight the managerial implications for success. N2 - Die Entwicklung neuer digitaler Produktinnovation erfordert in etablierten Industrieunternehmen die Integration von digitalen und physischen Elementen. Dies ist besonders in der Automobilindustrie sichtbar, wo der Trend zu vernetzter, autonomer, gemeinsam genutzter und elektrischer Mobilität zu einem neuen Wettbewerb führt, welcher etablierte Marktteilnehmer bedroht. Diese müssen lernen wie die Integration von gegensätzlichen Produktarchitekturen und Organisationsprinzipien aus der digitalen und physischen Produktentwicklung funktioniert. Die vorliegende Dissertation widmet sich diesem Problem. Basierend auf einer Fallstudie einer digitalen Produktinnovationsinitiative eines Premiummobilitätsanbieters rund um die Integration von Over-the-Air-Technologie für Software-Updates liefert sie wichtige Erkenntnisse. Erstens, etablierte Organisationen müssen Ihre Produktarchitektur befähigen, um verschiedene Produktarchitekturprinzipien in Einklang zu bringen. Zweitens, verschiedene Produktentwicklungsprozesse pro Produktebene müssen aufeinander abgestimmt werden. Drittens, die Organisationsstruktur muss erweitert werden, um die verschiedenen Produktebenen abzubilden. Darüber hinaus müssen auch Ressourcenallokationsprozesse auf die Entwicklungsprozesse abgestimmt werden. Basierend auf diesen Erkenntnissen und mit der bestehenden Fachliteratur wird in der Dissertation ein Prozessmodell entwickelt, welches erklären soll, wie etablierte Industrieunternehmen digitale Produktinnovation erreichen. Kernauslöser sind externer Marktdruck sowie existierende Architekturprinzipien. Wechselseitige Mechanismen wie die Befähigung der Produktarchitektur, die Erweiterung der Organisationstruktur, die Anpassung der Produktentwicklungsprozesse und die Anpassung der Ressourcenallokationsprozesse erklären den Prozess welcher in einer neuen Produktarchitektur sowie einer erweiterten Organisationsstruktur mündet. Der Forschungsbeitrag der Arbeit liegt im Bereich der digitalen Produktinnovation. Sie verlagert den Forschungsfokus auf Fragen der Produktarchitektur und verbindet diese durch Konzepte der Modularität mit organisatorischen Fragestellungen. Für die Praxis ergeben sich vier Hebel die Entscheidungsträger/innen nutzen können, um die Fähigkeiten zur digitalen Produktinnovation zu stärken.

A pressing challenge is thus to limit our impact on nature, and this requires detailed understanding of the interconnections between the environment, biodiversity and ecosystem functioning. These three components of ecosystems each include multiple dimensions, which interact with each other in different ways, but we lack a comprehensive picture of their interconnections and underlying mechanisms. Notably, diversity is often viewed as a single facet, namely species diversity, while many more facets exist at different levels of biological organisation (e.g. genetic, phenotypic, functional, multitrophic diversity), and multiple diversity facets together constitute the raw material for adaptation to environmental changes and shape ecosystem functioning. Consequently, investigating the multidimensionality of ecosystems, and in particular the links between multifaceted diversity, environmental changes and ecosystem functions, is crucial for ecological research, management and conservation. This thesis aims to explore several aspects of this question theoretically. I investigate three broad topics in this thesis. First, I focus on how food webs with varying levels of functional diversity across three trophic levels buffer environmental changes, such as a sudden addition of nutrients or long-term changes (e.g. warming or eutrophication). I observed that functional diversity generally enhanced ecological stability (i.e. the buffering capacity of the food web) by increasing trophic coupling. More precisely, two aspects of ecological stability (resistance and resilience) increased even though a third aspect (the inverse of the time required for the system to reach its post-perturbation state) decreased with increasing functional diversity. Second, I explore how several diversity facets served as a raw material for different sources of adaptation and how these sources affected multiple ecosystem functions across two trophic levels. Considering several sources of adaptation enabled the interplay between ecological and evolutionary processes, which affected trophic coupling and thereby ecosystem functioning. Third, I reflect further on the multifaceted nature of diversity by developing an index K able to quantify the facet of functional diversity, which is itself multifaceted. K can provide a comprehensive picture of functional diversity and is a rather good predictor of ecosystem functioning. Finally I synthesise the interdependent mechanisms (complementarity and selection effects, trophic coupling and adaptation) underlying the relationships between multifaceted diversity, ecosystem functioning and the environment, and discuss the generalisation of my findings across ecosystems and further perspectives towards elaborating an operational biodiversity-ecosystem functioning framework for research and conservation. N2 - Menschliche Aktivität verändert die Natur weltweit durch Einflussnahme auf die Umwelt, Biodiversität und Funktionsweise von Ökosystemen, die wiederum Ökosystemdienstleistungen stören und sich negativ auf den Menschen auswirken. Eine dringende Herausforderung besteht daher darin, unsere Wirkung auf die Natur zu begrenzen, was ein tiefgreifendes Verständnis der Zusammenhänge zwischen Umwelt, Biodiversität und dem Funktionalität von Ökosystemen voraussetzt. Diese drei Komponenten von Ökosystemen umfassen jedoch jeweils mehrere Dimensionen, die auf unterschiedliche Weise interagieren, und bisher haben wir kein umfassendes Bild von ihren Zusammenhängen und den zugrundeliegenden Mechanismen. Vor allem Diversität wird oft als eine einzige Facette betrachtet, nämlich als Artendiversität, während es auf verschiedenen biologischen Organisationsebenen viele weitere Facetten gibt, z. B. genetische, phänotypische, funktionelle, multitrophische Diversität, die zusammen mehrere Quellen für Rohmaterial zur die Anpassung an Umweltveränderungen bilden und die Funktionsweise von Ökosystemen beeinflussen. Folglich ist die Untersuchung der Multidimensionalität von Ökosystemen, insbesondere der Zusammenhänge zwischen multifacettierter Diversität, Umweltveränderungen und Ökosystemfunktionen, von entscheidender Bedeutung für Forschung, Management und Naturschutz. In dieser Arbeit sollen mehrere Aspekte dieser Frage theoretisch untersucht werden. In dieser Arbeit untersuche ich drei große Themenbereiche. Erstens konzentriere ich mich auf die Frage, wie Nahrungsnetze mit unterschiedlichem Grad funktioneller Diversität auf drei trophischen Ebenen Umweltveränderungen abpuffern, wie etwa eine plötzliche Zugabe von Nährstoffen oder langfristige Veränderungen (z. B. Erwärmung oder Eutrophierung). Hier habe ich festgestellt, dass die funktionelle Diversität die ökologische Stabilität (d. h. die Pufferkapazität des Nahrungsnetzes) durch eine stärkere trophische Kopplung allgemein erhöht. Im Speziellen nahmen zwei Aspekte der ökologischen Stabilität (Resistenz und Resilienz) zu, obwohl ein dritter Aspekt, der Kehrwert der Zeit, die das System benötigt, um den Post-Störungszustand zu erreichen, mit zunehmender funktioneller Diversität abnahm. Zweitens untersuche ich, wie mehrere Facetten der Diversität als Basis für mehrere Anpassungsprozesse aus verschiedenen Quellen dienten und wie diese Quellen mehrere Ökosystemfunktionen auf zwei trophischen Ebenen beeinflussten. Die Berücksichtigung mehrerer Anpassungsquellen ermöglichte das Zusammenspiel zwischen ökologischen und evolutionären Prozessen, die sich auf die trophische Kopplung und damit auf die Funktionalität des Ökosystems auswirkten. Drittens reflektiere ich weiter über die Facetten der Diversität, indem ich einen Index K entwickle, der die Facette der funktionalen Diversität quantifizieren kann, welche wiederum selbst vielschichtig ist. K kann ein umfassendes Bild der funktionellen Diversität vermitteln und ist ein recht guter Prädiktor für das Funktionieren von Ökosystemen. Schließlich fasse ich die voneinander abhängigen Mechanismen (Komplementarität und Selektionseffekte, trophische Kopplung und Anpassung) zusammen, die den Beziehungen zwischen multi-facettierter Diversität, dem Funktionieren von Ökosystemen und der Umwelt zugrunde liegen, und erörtere die Möglichkeiten zur Verallgemeinerung meiner Ergebnisse über Ökosysteme hinweg sowie Perspektiven für die Ausarbeitung eines operativen Rahmens für der Biodiversität-Ökosystem- Funktionalität für Forscher und Anwender.

They provide a framework that captures many of the central problems of computer science with close ties to various other fields of science. Thus, many studies over the last four decades have been devoted to the algorithmic complexity of homomorphism problems. Despite their generality, it has been found that non-uniform homomorphism problems, where the target structure is fixed, frequently feature complexity dichotomies. Exploring the limits of these dichotomies represents the common goal of this line of research. We investigate the problem of counting homomorphisms to a fixed structure over a finite field of prime order and its algorithmic complexity. Our emphasis is on graph homomorphisms and the resulting problem #_{p}Hom[H] for a graph H and a prime p. The main research question is how counting over a finite field of prime order affects the complexity. In the first part of this thesis, we tackle the research question in its generality and develop a framework for studying the complexity of counting problems based on category theory. In the absence of problem-specific details, results in the language of category theory provide a clear picture of the properties needed and highlight common ground between different branches of science. The proposed problem #Mor^{C}[B] of counting the number of morphisms to a fixed object B of C is abstract in nature and encompasses important problems like constraint satisfaction problems, which serve as a leading example for all our results. We find explanations and generalizations for a plethora of results in counting complexity. Our main technical result is that specific matrices of morphism counts are non-singular. The strength of this result lies in its algebraic nature. First, our proofs rely on carefully constructed systems of linear equations, which we know to be uniquely solvable. Second, by exchanging the field that the matrix is defined by to a finite field of order p, we obtain analogous results for modular counting. For the latter, cancellations are implied by automorphisms of order p, but intriguingly we find that these present the only obstacle to translating our results from exact counting to modular counting. If we restrict our attention to reduced objects without automorphisms of order p, we obtain results analogue to those for exact counting. This is underscored by a confluent reduction that allows this restriction by constructing a reduced object for any given object. We emphasize the strength of the categorial perspective by applying the duality principle, which yields immediate consequences for the dual problem of counting the number of morphisms from a fixed object. In the second part of this thesis, we focus on graphs and the problem #_{p}Hom[H]. We conjecture that automorphisms of order p capture all possible cancellations and that, for a reduced graph H, the problem #_{p}Hom[H] features the complexity dichotomy analogue to the one given for exact counting by Dyer and Greenhill. This serves as a generalization of the conjecture by Faben and Jerrum for the modulus 2. The criterion for tractability is that H is a collection of complete bipartite and reflexive complete graphs. From the findings of part one, we show that the conjectured dichotomy implies dichotomies for all quantum homomorphism problems, in particular counting vertex surjective homomorphisms and compactions modulo p. Since the tractable cases in the dichotomy are solved by trivial computations, the study of the intractable cases remains. As an initial problem in a series of reductions capable of implying hardness, we employ the problem of counting weighted independent sets in a bipartite graph modulo prime p. A dichotomy for this problem is shown, stating that the trivial cases occurring when a weight is congruent modulo p to 0 are the only tractable cases. We reduce the possible structure of H to the bipartite case by a reduction to the restricted homomorphism problem #_{p}Hom^{bip}[H] of counting modulo p the number of homomorphisms between bipartite graphs that maintain a given order of bipartition. This reduction does not have an impact on the accessibility of the technical results, thanks to the generality of the findings of part one. In order to prove the conjecture, it suffices to show that for a connected bipartite graph that is not complete, #_{p}Hom^{bip}[H] is #_{p}P-hard. Through a rigorous structural study of bipartite graphs, we establish this result for the rich class of bipartite graphs that are (K_{3,3}\{e}, domino)-free. This overcomes in particular the substantial hurdle imposed by squares, which leads us to explore the global structure of H and prove the existence of explicit structures that imply hardness. N2 - Homomorphismen sind ein grundlegendes Konzept der Mathematik, das die Ähnlichkeit von Strukturen ausdrückt. Sie bieten einen Rahmen, der viele der zentralen Probleme der Informatik umfasst und enge Verbindungen zu verschiedenen Wissenschaftsbereichen aufweist. Aus diesem Grund haben sich in den letzten vier Jahrzehnten viele Studien mit der algorithmischen Komplexität von Homomorphismusproblemen beschäftigt. Trotz ihrer Allgemeingültigkeit wurden Komplexitätsdichotomien häufig für nicht-uniforme Homomorphismusprobleme nachgewiesen, bei denen die Zielstruktur fixiert ist. Die Grenzen dieser Dichotomien zu erforschen, ist das gemeinsame Ziel dieses Forschungskalküls. Wir untersuchen das Problem und seine algorithmische Komplexität, Homomorphismen zu einer festen Struktur über einem endlichen Körper mit Primzahlordnung zu zählen. Wir konzentrieren uns auf Graphenhomomorphismen und das daraus resultierende Problem #_{p}Hom[H] für einen Graphen H und eine Primzahl p. Die Hauptforschungsfrage ist, wie das Zählen über einem endlichen Körper mit Primzahlordnung die Komplexität beeinflusst. Im ersten Teil wird die Forschungsfrage in ihrer Allgemeinheit behandelt und ein Rahmen für die Untersuchung der Komplexität von Zählproblemen auf der Grundlage der Kategorientheorie entwickelt. Losgelöst von problemspezifischen Details liefern die Ergebnisse in der Sprache der Kategorientheorie ein klares Bild der benötigten Eigenschaften und zeigen Gemeinsamkeiten zwischen verschiedenen Wissenschaftsgebieten auf. Das vorgeschlagene Problem #Mor^{C}[B] des Zählens der Anzahl von Morphismen zu einem festen Objekt B von C ist abstrakter Natur und umfasst wichtige Probleme wie Constraint Satisfaction Problems, die als leitendes Beispiel für alle unsere Ergebnisse dienen. Wir finden Erklärungen und Verallgemeinerungen für eine Vielzahl von Ergebnissen in der Komplexitätstheorie von Zählproblemen. Unser wichtigstes technisches Ergebnis ist, dass bestimmte Matrizen von Morphismenzahlen nicht singulär sind. Die Stärke dieses Ergebnisses liegt in seiner algebraischen Natur. Erstens basieren unsere Beweise auf sorgfältig konstruierten linearen Gleichungssystemen, von denen wir wissen, dass sie eindeutig lösbar sind. Zweitens, indem wir den Körper, über dem die Matrix definiert ist, durch einen endlichen Körper der Ordnung p ersetzen, erhalten wir analoge Ergebnisse für das modulare Zählen. Für letztere sind Annullierungen durch Automorphismen der Ordnung p impliziert, aber faszinierenderweise stellen diese das einzige Hindernis für die Übertragung unserer Ergebnisse von der exakten auf die modulare Zählung dar. Wenn wir unsere Aufmerksamkeit auf reduzierte Objekte ohne Automorphismen der Ordnung p beschränken, erhalten wir Ergebnisse, die zu denen des exakten Zählens analog sind. Dies wird durch eine konfluente Reduktion unterstrichen, die für jedes beliebige Objekt ein reduziertes Objekt konstruiert. Wir heben die Stärke der kategorialen Perspektive durch die Anwendung des Dualitätsprinzips hervor, das direkte Konsequenzen für das duale Problem des Zählens der Anzahl der Morphismen von einem fixen Objekts aus liefert. Im zweiten Teil konzentrieren wir uns auf Graphen und das Problem #_{p}Hom[H]. Wir stellen die Vermutung auf, dass Automorphismen der Ordnung p alle möglichen Annullierungen erklären und dass das Problem #_{p}Hom[H] für einen reduzierten Graphen H eine Komplexitätsdichotomie analog zu der aufweist, die von Dyer und Greenhill für das exakte Zählen bewiesen wurde. Dies stellt eine Verallgemeinerung der Vermutung von Faben und Jerrum für den Modulus 2 dar. Das Kriterium für die effiziente Lösbarkeit ist, dass H lediglich aus vollständigen bipartiten und reflexiven vollständigen Graphen besteht. Basierend auf den Ergebnisse des ersten Teils zeigen wir, dass die Vermutung Dichotomien für alle Quantenhomomorphismenprobleme impliziert, insbesondere für das Zählen modulo p von Homomorphismen surjektiv auf Knoten und von Verdichtungen. Da die effizient lösbaren Fälle in der Dichotomie durch triviale Berechnungen gelöst werden, bleibt es, die unlösbaren Fälle zu untersuchen. Als erstes Problem in einer Reihe von Reduktionen, deren Ziel es ist, Härte zu implizieren, verwenden wir das Problem des Zählens gewichteter unabhängiger Mengen in einem bipartiten Graphen modulo p. Für dieses Problem beweisen wir eine Dichotomie, die besagt, dass nur die trivialen Fälle effizient lösbar sind. Diese treten auf, wenn ein Gewicht kongruent modulo p zu 0 ist. Durch eine Reduktion auf das eingeschränkte Homomorphismusproblem #_{p}Hom^{bip}[H] reduzieren wir die mögliche Struktur von H auf den bipartiten Fall. Hierbei handelt es sich um das Problem des Zählens modulo p der Homomorphismen zwischen bipartiten Graphen, die eine gegebene Ordnung der Bipartition erhalten. Dank der Allgemeingültigkeit der Ergebnisse des ersten Teils hat diese Reduktion keinen Einfluss auf die Verfügbarkeit der technischen Ergebnisse. Für einen Beweis der Vermutung genügt es zu zeigen, dass #_{p}Hom^{bip}[H] für einen zusammenhängenden und nicht vollständigen bipartiten Graphen #_{p}P-schwer ist. Durch eine rigorose Untersuchung der Struktur von bipartiten Graphen beweisen wir dieses Ergebnis für die umfangreiche Klasse von bipartiten Graphen, die (K_{3,3}\{e}, domino)-frei sind. Dies überwindet insbesondere die substantielle Hürde, die durch Quadrate gegeben ist und uns dazu veranlasst, die globale Struktur von H zu untersuchen und die Existenz expliziter Strukturen zu beweisen, die Härte implizieren.

Importantly, the human brain inherits from evolution a predisposition to map cardinality onto space, as revealed by the presence of spatial-numerical associations (SNAs) in humans and animals. Here, the mapping of cardinal information onto physical space is addressed as a hallmark signature characterizing numerical cognition. According to traditional approaches, cognition is defined as complex forms of internal information processing, taking place in the brain (cognitive processor). On the contrary, embodied cognition approaches define cognition as functionally linked to perception and action, in the continuous interaction between a biological body and its physical and sociocultural environment. Embracing the principles of the embodied cognition perspective, I conducted four novel studies designed to unveil how SNAs originate, develop, and adapt, depending on characteristics of the organism, the context, and their interaction. I structured my doctoral thesis in three levels. At the grounded level (Study 1), I unfold the biological foundations underlying the tendency to map cardinal information across space; at the embodied level (Study 2), I reveal the impact of atypical motor development on the construction of SNAs; at the situated level (Study 3), I document the joint influence of visuospatial attention and task properties on SNAs. Furthermore, I experimentally investigate the presence of associations between physical and numerical distance, another numerical property fundamental for the development of efficient mathematical minds (Study 4). In Study 1, I present the Brain’s Asymmetric Frequency Tuning hypothesis that relies on hemispheric asymmetries for processing spatial frequencies, a low-level visual feature that the (in)vertebrate brain extracts from any visual scene to create a coherent percept of the world. Computational analyses of the power spectra of the original stimuli used to document the presence of SNAs in human newborns and animals, support the brain’s asymmetric frequency tuning as a theoretical account and as an evolutionarily inherited mechanism scaffolding the universal and innate tendency to represent cardinality across horizontal space. In Study 2, I explore SNAs in children with rare genetic neuromuscular diseases: spinal muscular atrophy (SMA) and Duchenne muscular dystrophy (DMD). SMA children never accomplish independent motoric exploration of their environment; in contrast, DMD children do explore but later lose this ability. The different SNAs reported by the two groups support the critical role of early sensorimotor experiences in the spatial representation of cardinality. In Study 3, I directly compare the effects of overt attentional orientation during explicit and implicit processing of numerical magnitude. First, the different effects of attentional orienting based on the type of assessment support different mechanisms underlying SNAs during explicit and implicit assessment of numerical magnitude. Secondly, the impact of vertical shifts of attention on the processing of numerical distance sheds light on the correspondence between numerical distance and peri-personal distance. In Study 4, I document the presence of different SNAs, driven by numerical magnitude and numerical distance, by employing different response mappings (left vs. right and near vs. distant). In the field of numerical cognition, the four studies included in the present thesis contribute to unveiling how the characteristics of the organism and the environment influence the emergence, the development, and the flexibility of our attitude to represent cardinal information across space, thus supporting the predictions of the embodied cognition approach. Furthermore, they inform a taxonomy of body-centred factors (biological properties of the brain and sensorimotor system) modulating the spatial representation of cardinality throughout the course of life, at the grounded, embodied, and situated levels. If the awareness for different variables influencing SNAs over the course of life is important, it is equally important to consider the organism as a whole in its sensorimotor interaction with the world. Inspired by my doctoral research, here I propose a holistic perspective that considers the role of evolution, embodiment, and environment in the association of cardinal information with directional space. The new perspective advances the current approaches to SNAs, both at the conceptual and at the methodological levels. Unveiling how the mental representation of cardinality emerges, develops, and adapts is necessary to shape efficient mathematical minds and achieve economic productivity, technological progress, and a higher quality of life. N2 - Unter den verschiedenen Bedeutungsaspekten numerischer Informationen ist die Kardinalität fundamental für das Überleben und die Entwicklung grundlegender sowie fortgeschrittener numerischer Fähigkeiten. Ein wichtiger Aspekt ist, dass das menschliche Gehirn evolutionär die Prädisposition besitzt, Kardinalität auf den Raum abzubilden, wie das Vorhandensein von räumlich-numerischen Assoziationen [engl. spatial-numerical associations, SNA] bei Menschen und Tieren zeigt. Hier wird die Abbildung kardinaler Informationen auf den physischen Raum als charakteristisches Merkmal der numerischen Kognition untersucht. Nach traditionellen Ansätzen wird Kognition als eine komplexe Form der internen Informationsverarbeitung definiert, die im Gehirn stattfindet (kognitiver Prozessor). Im Gegensatz dazu betrachten Ansätze der verkörperten Kognition (Embodied Cognition) Kognition als funktionell mit Wahrnehmung und Handlung verbunden, eingebettet in die kontinuierliche Interaktion zwischen einem biologischen Körper und seiner physischen sowie soziokulturellen Umgebung. In Anlehnung an die Prinzipien der Embodied-Cognition-Perspektive habe ich vier innovative Studien durchgeführt, um herauszufinden, wie SNA in Abhängigkeit von den Merkmalen des Organismus, des Kontexts und ihrer Interaktion entstehen, sich entwickeln und anpassen. Meine Doktorarbeit ist auf drei Ebenen strukturiert. Auf der geerdeten („grounded“) Ebene (Studie 1) zeige ich die biologischen Grundlagen auf, die der Tendenz zugrunde liegen, kardinale Informationen über den Raum hinweg abzubilden; auf der verkörperten („embodied“) Ebene (Studie 2) zeige ich die Auswirkungen einer atypischen motorischen Entwicklung auf die Konstruktion von SNA; auf der situativen („situated“) Ebene (Studie 3) dokumentiere ich den gemeinsamen Einfluss von visuell-räumlicher Aufmerksamkeit und von Aufgabeneigenschaften auf SNA. Darüber hinaus untersuche ich experimentell das Vorliegen von Assoziationen zwischen physischer und numerischer Distanz, einer weiteren numerischen Eigenschaft, die für die Entwicklung eines effizienten mathematischen Verstandes grundlegend ist (Studie 4). In Studie 1 stelle ich die Hypothese der asymmetrischen Frequenzabstimmung des Gehirns vor, die sich auf hemisphärische Asymmetrien bei der Verarbeitung räumlicher Frequenzen stützt. Diese räumlichen Frequenzen sind ein visuelles Merkmal auf niedriger Verarbeitungsebene, das das Gehirn von (Nicht-)Wirbeltieren aus jeder visuellen Szene extrahiert, um eine kohärente Wahrnehmung der Welt zu gewährleisten. Computergestützte Analysen der Leistungsspektren der ursprünglichen Stimuli, die verwendet wurden, um die Existenz von SNA bei menschlichen Neugeborenen und Tieren zu dokumentieren, unterstützen die asymmetrische Frequenzabstimmung des Gehirns als theoretische Erklärung. Dieser evolutionär vererbte Mechanismus könnte die universelle und angeborene Tendenz zur Darstellung von Kardinalität im horizontalen Raum erklären. In Studie 2 untersuche ich SNA bei Kindern mit seltenen genetisch bedingten neuromuskulären Krankheiten, nämlich Spinaler Muskelatrophie (SMA) und Duchenne-Muskeldystrophie (DMD). Kinder mit SMA sind nicht in der Lage, ihre Umwelt selbstständig motorisch zu erkunden, während Kinder mit DMD diese Fähigkeit anfangs besitzen, sie aber im Laufe der Zeit verlieren. Die unterschiedlichen SNA, die von den beiden Gruppen berichtet werden, belegen die entscheidende Rolle früher sensomotorischer Erfahrungen für die räumliche Repräsentation von Kardinalität. In Studie 3 vergleiche ich direkt die Auswirkungen der offenen Aufmerksamkeitsorientierung während der expliziten und impliziten Verarbeitung numerischer Größenordnungen. Erstens zeigen die unterschiedlichen Auswirkungen der Aufmerksamkeitsorientierung je nach Art der Bewertung unterschiedliche Mechanismen auf, die den SNA bei der expliziten und impliziten Beurteilung numerischer Größen zugrunde liegen. Zweitens deutet die Wirkung der vertikalen Aufmerksamkeitsverschiebung auf die Verarbeitung numerischer Distanzen auf eine Korrelation zwischen numerischer Distanz und peripersonaler Distanz hin. In Studie 4 belege ich das Vorliegen unterschiedlicher SNA, die durch numerische Größe und numerische Distanz gesteuert werden, mittels verschiedener Antwortzuordnungen (links vs. rechts und nah vs. fern). Die vier Studien dieser Arbeit auf dem Gebiet der numerischen Kognition zeigen, wie die Eigenschaften des Organismus und der Umwelt die Entstehung, Entwicklung und Flexibilität der Fähigkeit beeinflussen, kardinale Informationen über den Raum hinweg zu repräsentieren, und unterstützen damit die Vorhersagen des Ansatzes der verkörperten Kognition. Darüber hinaus liefern sie Einblicke in eine Taxonomie körperbezogener Faktoren, darunter biologische Merkmale des Gehirns und des sensomotorischen Systems, die die räumliche Repräsentation von Kardinalität im Laufe des Lebens auf den „grounded“, „embodied“ und „situated“ Ebenen modulieren. Die Kenntnis der verschiedenen Variablen, die die SNA im Laufe des Lebens beeinflussen, ist ebenso wichtig wie die Betrachtung des Organismus als Ganzes in seiner sensomotorischen Interaktion mit der Welt. Inspiriert von meiner Doktorarbeit schlage ich hier eine ganzheitliche Perspektive vor, die die Rolle der Evolution, der Verkörperung und der Umwelt bei unserer Assoziation von kardinalen Informationen mit Raum berücksichtigt. Diese neue Perspektive erweitert die derzeitigen Ansätze zu SNA sowohl auf konzeptioneller als auch auf methodologischer Ebene. Die Erforschung der Entstehung, Entwicklung und Anpassung der mentalen Repräsentation von Kardinalität ist entscheidend, um effiziente mathematische Fähigkeiten zu entwickeln sowie wirtschaftliche Produktivität, technologischen Fortschritt und eine verbesserte Lebensqualität zu fördern.

However, our knowledge about dense matter explored in the cores of neutron stars remains limited. Fortunately, dense matter is not probed only in astrophysical observations, but also in terrestrial heavy-ion collision experiments. Here we use Bayesian inference to combine data from astrophysical multi-messenger observations of neutron stars(1-9) and from heavy-ion collisions of gold nuclei at relativistic energies(10,11) with microscopic nuclear theory calculations(12-17) to improve our understanding of dense matter. We find that the inclusion of heavy-ion collision data indicates an increase in the pressure in dense matter relative to previous analyses, shifting neutron-star radii towards larger values, consistent with recent observations by the Neutron Star Interior Composition Explorer mission(5-8,18). Our findings show that constraints from heavy-ion collision experiments show a remarkable consistency with multi-messenger observations and provide complementary information on nuclear matter at intermediate densities. This work combines nuclear theory, nuclear experiment and astrophysical observations, and shows how joint analyses can shed light on the properties of neutron-rich supranuclear matter over the density range probed in neutron stars.

N2 - “Inventing and creating music” has great potential for music education: experimenting with sounds, developing a feel for dramaturgical progressions, communicating non-verbally - inventing and creating music opens up a broad field of musical activities and experiential possibilities. However, in regular music lessons in Swiss elementary school, didactic approaches to production are still the exception rather than the rule and music teachers lack guidance strategies. For this book, the author used a design-based research study to investigate how primary school teachers gradually develop their instruction strategies when carrying out musical creation processes in their classrooms. The researcher accompanied the teachers in their school practice and intervened specifically with reflection impulses to support the professionalization process. Three reflection tools were generated from this: The reflection tool “try-outs” contains concrete suggestions for action and reflection questions for guiding musical design processes. The online tool “improspider” is a self-reflection instrument for assessing personal orientation. The competence model “competence flyer” offers a reflection foil for the control of independent competence acquisition steps. The reflection tools are also available online in the form of a learning object.

The six currently valid nominal species are rainforest frogs known from few individuals, hampering a full understanding of the species diversity of the clade. We assembled data on specimens collected during field surveys over the past 30 years and integrated analysis of mitochondrial and nuclear-encoded genes of 88 individuals, a comprehensive bioacoustic analysis, and morphological comparisons to delimit a minimum of nine species-level lineages in the subgenus. To clarify the identity of the species Gephyromantis malagasius, we applied a target-enrichment approach to a sample of the 110 year old holotype of Microphryne malagasia Methuen and Hewitt, 1913 to assign this specimen to a lineage based on a mitochondrial DNA barcode. The holotype clustered unambiguously with specimens previously named G. ventrimaculatus. Consequently we propose to consider Trachymantis malagasia ventrimaculatus Angel, 1935 as a junior synonym of Gephyromantis malagasius. Due to this redefinition of G. malagasius, no scientific name is available for any of the four deep lineages of frogs previously subsumed under this name, all characterized by red color ventrally on the hindlimbs. These are here formally named as Gephyromantis fiharimpe sp. nov., G. matsilo sp. nov., G. oelkrugi sp. nov., and G. portonae sp. nov. The new species are distinguishable from each other by genetic divergences of >4% uncorrected pairwise distance in a fragment of the 16S rRNA marker and a combination of morphological and bioacoustic characters. Gephyromantis fiharimpe and G. matsilo occur, respectively, at mid-elevations and lower elevations along a wide stretch of Madagascar's eastern rainforest band, while G. oelkrugi and G. portonae appear to be more range-restricted in parts of Madagascar's North East and Northern Central East regions. Open taxonomic questions surround G. horridus, to which we here assign specimens from Montagne d'Ambre and the type locality Nosy Be; and G. ranjomavo, which contains genetically divergent populations from Marojejy, Tsaratanana, and Ampotsidy.

A detailed evaluation of its major endoscopic features compared with Parkinson's disease (PD) is lacking. Objective This study systematically assessed dysphagia in MSA compared with PD and correlated subjective dysphagia to objective endoscopic findings. Methods Fifty-seven patients with MSA (median, 64 [interquartile range (IQR): 59-71] years; 35 women) underwent flexible endoscopic evaluation of swallowing using a specific MSA-flexible endoscopic evaluation of swallowing task protocol. Findings were compared with an age-matched cohort of 57 patients with PD (median, 67 [interquartile range: 60-73] years; 28 women). In a subcohort, subjective dysphagia was assessed using the Swallowing Disturbance Questionnaire and correlated to endoscopy findings. Results Patients with MSA predominantly showed symptoms suggestive of oral-phase disturbance (premature spillage, 75.4%, piecemeal deglutition, 75.4%). Pharyngeal-phase symptoms occurred less often (pharyngeal residues, 50.9%; penetration/aspiration, 28.1%). In contrast, pharyngeal symptoms were the most common finding in PD (pharyngeal residues, 47.4%). Oral symptoms occurred less frequently in PD (premature spillage, 15.8%, P < 0.001; piecemeal deglutition, 1.8%, P < 0.01). Patients with MSA had a greater risk for oral-phase disturbances with increased disease severity (P < 0.05; odds ratio, 3.15). Patients with MSA showed a significantly higher intraindividual interswallow variability compared with PD. When correlating Swallowing Disturbance Questionnaire scores with endoscopy results, its cutoff, validated for PD, was not sensitive enough to identify patients with MSA with dysphagia. We developed a subscore for identifying dysphagia in MSA and calculated a new cutoff (sensitivity 85%, specificity 100%). Conclusions In contrast with patients with PD, patients with dysphagic MSA more frequently present with oral-phase symptoms and a significantly higher intraindividual interswallow variability. A novel Swallowing Disturbance Questionnaire MSA subscore may be a valuable tool to identify patients with MSA with early oropharyngeal dysphagia.

T1 - Orbital controls on eastern African hydroclimate in the Pleistocene JF - Scientific reports N2 - Understanding eastern African paleoclimate is critical for contextualizing early human evolution, adaptation, and dispersal, yet Pleistocene climate of this region and its governing mechanisms remain poorly understood due to the lack of long, orbitally-resolved, terrestrial paleoclimate records. Here we present leaf wax hydrogen isotope records of rainfall from paleolake sediment cores from key time windows that resolve long-term trends, variations, and high-latitude effects on tropical African precipitation. Eastern African rainfall was dominantly controlled by variations in low-latitude summer insolation during most of the early and middle Pleistocene, with little evidence that glacial-interglacial cycles impacted rainfall until the late Pleistocene. We observe the influence of high-latitude-driven climate processes emerging from the last interglacial (Marine Isotope Stage 5) to the present, an interval when glacial-interglacial cycles were strong and insolation forcing was weak. Our results demonstrate a variable response of eastern African rainfall to low-latitude insolation forcing and high-latitude-driven climate change, likely related to the relative strengths of these forcings through time and a threshold in monsoon sensitivity. We observe little difference in mean rainfall between the early, middle, and late Pleistocene, which suggests that orbitally-driven climate variations likely played a more significant role than gradual change in the relationship between early humans and their environment.

T1 - Health app policy BT - international comparison of nine countries' approaches JF - npj digital medicine N2 - An abundant and growing supply of digital health applications (apps) exists in the commercial tech-sector, which can be bewildering for clinicians, patients, and payers. A growing challenge for the health care system is therefore to facilitate the identification of safe and effective apps for health care practitioners and patients to generate the most health benefit as well as guide payer coverage decisions. Nearly all developed countries are attempting to define policy frameworks to improve decision-making, patient care, and health outcomes in this context. This study compares the national policy approaches currently in development/use for health apps in nine countries. We used secondary data, combined with a detailed review of policy and regulatory documents, and interviews with key individuals and experts in the field of digital health policy to collect data about implemented and planned policies and initiatives. We found that most approaches aim for centralized pipelines for health app approvals, although some countries are adding decentralized elements. While the countries studied are taking diverse paths, there is nevertheless broad, international convergence in terms of requirements in the areas of transparency, health content, interoperability, and privacy and security. The sheer number of apps on the market in most countries represents a challenge for clinicians and patients. Our analyses of the relevant policies identified challenges in areas such as reimbursement, safety, and privacy and suggest that more regulatory work is needed in the areas of operationalization, implementation and international transferability of approvals. Cross-national efforts are needed around regulation and for countries to realize the benefits of these technologies.

But is women’s professional success viewed less positively when organizations commit to women’s advancement? Do equality commitments have positive effects on evaluations of successful men? We fielded a survey experiment with a national probability sample in Germany (N = 3229) that varied employees’ gender and their organization’s commitment to equality. Respondents read about a recently promoted employee and rated how decisive of a role they thought intelligence and effort played in getting the employee promoted from 1 “Not at all decisive” to 7 “Very decisive” and the fairness of the promotion from 1 “Very unfair” to 7 “Very fair.” When organizations committed to women’s advancement rather than uniform performance standards, people believed intelligence and effort were less decisive in women’s promotions, but that intelligence was more decisive in men’s promotions. People viewed women’s promotions as least fair and men’s as most fair in organizations committed to women’s advancement. However, women’s promotions were still viewed more positively than men’s in all conditions and on all outcomes, suggesting people believed that organizations had double standards for success that required women to be smarter and work harder to be promoted, especially in organizations that did not make equality commitments.

In this study, the antibacterial and osteogenic properties were simultaneously introduced in biomaterials, where copper nanoparticles (CuNPs) were generated by in situ reductions of Cu ions into a mussel-inspired hyperbranched polyglycerol (MI-hPG) coating via a simple dip-coating method. This hyperbranched polyglycerol with 10 % catechol groups' modification presents excellent antifouling property, which could effectively reduce bacteria adhesion on the surface. In this work, polycaprolactone (PCL) electrospun fiber membrane was selected as the substrate, which is commonly used in biomedical implants in bone regeneration and cardiovascular stents because of its good biocompatibility and easy post-modification. The as-fabricated CuNPs-incorporated PCL membrane [PCL-(MI-hPG)-CuNPs] was confirmed with effective antibacterial performance via in vitro antibacterial tests against Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), and multi-resistant E. coli. In addition, the in vitro results demonstrated that osteogenic property of PCL-(MI-hPG)-CuNPs was realized by upregulating the osteoblast-related gene expressions and protein activity. This study shows that antibacterial and osteogenic properties can be balanced in a surface coating by introducing CuNPs.

Soil moisture influences flood generation processes and during droughts when precipitation is absent, it provides plant with transpirable water, thereby sustaining plant growth and survival in agriculture and natural ecosystems. Soil moisture stored in deeper soil layers e.g. below 100 cm is of particular importance for providing plant transpirable water during dry periods. Not being directly connected to the atmosphere and located outside soil layers with the highest root densities, water in these layers is less susceptible to be rapidly evaporated and transpired. Instead, it provides longer-term soil water storage increasing the drought tolerance of plants and ecosystems. Given the importance of soil moisture in the context of hydro-meteorological extremes in a warming climate, its monitoring is part of official national adaption strategies to a changing climate. Yet, soil moisture is highly variable in time and space which challenges its monitoring on spatio-temporal scales relevant for flood and drought risk modelling and forecasting. Introduced over a decade ago, Cosmic-Ray Neutron Sensing (CRNS) is a noninvasive geophysical method that allows for the estimation of soil moisture at relevant spatio-temporal scales of several hectares at a high, subdaily temporal resolution. CRNS relies on the detection of secondary neutrons above the soil surface which are produced from high-energy cosmic-ray particles in the atmosphere and the ground. Neutrons in a specific epithermal energy range are sensitive to the amount of hydrogen present in the surroundings of the CRNS neutron detector. Due to same mass as the hydrogen nucleus, neutrons lose kinetic energy upon collision and are subsequently absorbed when reaching low, thermal energies. A higher amount of hydrogen therefore leads to fewer neutrons being detected per unit time. Assuming that the largest amount of hydrogen is stored in most terrestrial ecosystems as soil moisture, changes of soil moisture can be estimated through an inverse relationship with observed neutron intensities. Although important scientific advancements have been made to improve the methodological framework of CRNS, several open challenges remain, of which some are addressed in the scope of this thesis. These include the influence of atmospheric variables such as air pressure and absolute air humidity, as well as, the impact of variations in incoming primary cosmic-ray intensity on observed epithermal and thermal neutron signals and their correction. Recently introduced advanced neutron-to-soil moisture transfer functions are expected to improve CRNS-derived soil moisture estimates, but potential improvements need to be investigated at study sites with differing environmental conditions. Sites with strongly heterogeneous, patchy soil moisture distributions challenge existing transfer functions and further research is required to assess the impact of, and correction of derived soil moisture estimates under heterogeneous site conditions. Despite its capability of measuring representative averages of soil moisture at the field scale, CRNS lacks an integration depth below the first few decimetres of the soil. Given the importance of soil moisture also in deeper soil layers, increasing the observational window of CRNS through modelling approaches or in situ measurements is of high importance for hydrological monitoring applications. By addressing these challenges, this thesis aids to closing knowledge gaps and finding answers to some of the open questions in CRNS research. Influences of different environmental variables are quantified, correction approaches are being tested and developed. Neutron-to-soil moisture transfer functions are evaluated and approaches to reduce effects of heterogeneous soil moisture distributions are presented. Lastly, soil moisture estimates from larger soil depths are derived from CRNS through modified, simple modelling approaches and in situ estimates by using CRNS as a downhole technique. Thereby, this thesis does not only illustrate the potential of new, yet undiscovered applications of CRNS in future but also opens a new field of CRNS research. Consequently, this thesis advances the methodological framework of CRNS for above-ground and downhole applications. Although the necessity of further research in order to fully exploit the potential of CRNS needs to be emphasised, this thesis contributes to current hydrological research and not least to advancing hydrological monitoring approaches being of utmost importance in context of intensifying hydro-meteorological extremes in a changing climate. N2 - Wasser, das als Bodenfeuchte in der ungesättigten Bodenzone gespeichert ist, beeinflusst zahlreiche hydrologische Prozesse. Sie ist von großer Bedeutung für hydrometeorologische Extremereignisse, da sie sowohl die Prozesse zur Entstehung von Hochwassereignissen beeinflusst als auch pflanzenverfügbares Wasser in Dürreperioden bereitstellt, in denen Regen ausbleibt. Vor allem Bodenfeuchte in tieferen Schichten des Bodens wird zum Beispiel durch die geringere Dichte an Pflanzenwurzeln langsamer aufgenommen und reduziert. Die Bodenfeuchte in diesen tieferen Schichten kann daher vor allem in Trockenperioden zum Überleben der Pflanzen in landwirtschaftlichen Gebieten und natürlichen Ökosystemen beitragen. Im Kontext hydro-meteorologischer Extremereignisse kommt der Bodenfeuchte so eine besondere Bedeutung zu und ist daher Teil nationaler Monitoring- und Anpassungsstrategien an sich verändernde Klimabedingungen. Cosmic-Ray Neutron Sensing (CRNS) ist ein geophysikalisches Messverfahren, das natürlich vorkommende Neutronen aus kosmischer Strahlung zur Bodenfeuchtebestimmung nutzt. Die Intensität der über dem Boden gemessenen Neutronen ist dabei abhängig von der Menge anWasserstoff in der Umgebung des Neutronendetektors. Da in den meisten Bereichen an Land die Bodenfeuchte den größten Teil des Wasserstoffs ausmacht, lassen Veränderungen in der gemessenen Neutronenintensität auf veränderte Bodenfeuchtebedingungen schließen. Ein Vorteil dieser nichtinvasiven Methode ist ihr großer Messbereich von mehreren Hektar. Die, selbst über kurze Distanzen und Zeiträume auftretenden, Unterschiede werden somit repräsentativ gemittelt und gemessene Bodenfeuchtewerte können so besser für Vorhersagemodelle von Hochwasser- und Dürreereignissen genutzt werden. Trotz des Potentials von CRNS für das Monitoring von Bodenfeuchte bleiben zahlreiche offene Forschungsfragen, von denen einige im Rahmen dieser Arbeit betrachtet werden. Hierzu zählt die Bestimmung und Korrektur von Einflussgrößen, die das Neutronensignal zusätzlich zur Bodenfeuchte beeinflussen. Ebenso gehört die Ableitung von Bodenfeuchte aus dem Neutronensignal selbst sowie der Umgang mit stark unterschiedlichen Bodenfeuchtebedingungen im Messbereich dazu. Obwohl CRNS einen großen horizontalen Messbereich besitzt, ist die Messtiefe auf die oberen ca. 30 cm des Bodens begrenzt. Hierzu werden Ansätze untersucht, die Bodenfeuchte mathematisch in größere Tiefen zu extrapolieren und sie direkt dort zu messen, indem Neutronendetektoren in Bohrlöchern installiert werden. Mit der Betrachtung der Forschungsfragen kann diese Arbeit einen wichtigen Beitrag zur Weiterentwicklung von CRNS und der Anwendbarkeit der Methode z.B. im Rahmen nationaler Monitoring-Programme leisten, denen im Kontext zunehmend intensiverer hydro-meteorologischer Extremereignisse eine besondere Bedeutung zukommt.

T1 - Overcoming natural biomass limitations in gram-negative bacteria through synthetic carbon fixation T1 - Überwindung natürlicher Biomasselimitationen in gramnegativen Bakterien mittels synthetischer Kohlenstofffixierung N2 - The carbon demands of an ever-increasing human population and the concomitant rise in net carbon emissions requires CO2 sequestering approaches for production of carbon-containing molecules. Microbial production of carbon-containing products from plant-based sugars could replace current fossil-based production. However, this form of sugar-based microbial production directly competes with human food supply and natural ecosystems. Instead, one-carbon feedstocks derived from CO2 and renewable energy were proposed as an alternative. The one carbon molecule formate is a stable, readily soluble and safe-to-store energetic mediator that can be electrochemically generated from CO2 and (excess off-peak) renewable electricity. Formate-based microbial production could represent a promising approach for a circular carbon economy. However, easy-to-engineer and efficient formate-utilizing microbes are lacking. Multiple synthetic metabolic pathways were designed for better-than-nature carbon fixation. Among them, the reductive glycine pathway was proposed as the most efficient pathway for aerobic formate assimilation. While some of these pathways have been successfully engineered in microbial hosts, these synthetic strains did so far not exceed the performance of natural strains. In this work, I engineered and optimized two different synthetic formate assimilation pathways in gram-negative bacteria to exceed the limits of a natural carbon fixation pathway, the Calvin cycle. The first chapter solidified Cupriavidus necator as a promising formatotrophic host to produce value-added chemicals. The formate tolerance of C. necator was assessed and a production pathway for crotonate established in a modularized fashion. Last, bioprocess optimization was leveraged to produce crotonate from formate at a titer of 148 mg/L. In the second chapter, I chromosomally integrated and optimized the synthetic reductive glycine pathway in C. necator using a transposon-mediated selection approach. The insertion methodology allowed selection for condition-specific tailored pathway expression as improved pathway performance led to better growth. I then showed my engineered strains to exceed the biomass yields of the Calvin cycle utilizing wildtype C. necator on formate. This demonstrated for the first time the superiority of a synthetic formate assimilation pathway and by extension of synthetic carbon fixation efforts as a whole. In chapter 3, I engineered a segment of a synthetic carbon fixation cycle in Escherichia coli. The GED cycle was proposed as a Calvin cycle alternative that does not perform a wasteful oxygenation reaction and is more energy efficient. The pathways simple architecture and reasonable driving force made it a promising candidate for enhanced carbon fixation. I created a deletion strain that coupled growth to carboxylation via the GED pathway segment. The CO2 dependence of the engineered strain and 13C-tracer analysis confirmed operation of the pathway in vivo. In the final chapter, I present my efforts of implementing the GED cycle also in C. necator, which might be a better-suited host, as it is accustomed to formatotrophic and hydrogenotrophic growth. To provide the carboxylation substrate in vivo, I engineered C. necator to utilize xylose as carbon source and created a selection strain for carboxylase activity. I verify activity of the key enzyme, the carboxylase, in the decarboxylative direction. Although CO2-dependent growth of the strain was not obtained, I showed that all enzymes required for operation of the GED cycle are active in vivo in C. necator. I then evaluate my success with engineering a linear and cyclical one-carbon fixation pathway in two different microbial hosts. The linear reductive glycine pathway presents itself as a much simpler metabolic solution for formate dependent growth over the sophisticated establishment of hard-to-balance carbon fixation cycles. Last, I highlight advantages and disadvantages of C. necator as an upcoming microbial benchmark organism for synthetic metabolism efforts and give and outlook on its potential for the future of C1-based manufacturing. N2 - Der Rohstoffbedarf einer ständig wachsenden menschlichen Bevölkerung und der damit einhergehende Anstieg der Kohlenstoffemissionen erfordert Konzepte zur CO2-Bindung für die Produktion von kohlenstoffhaltigen Molekülen. Hier bietet die mikrobielle Produktion von Chemikalien eine nachhaltige Alternative zu den bisher etablierten Syntheseprozessen. Da die Nutzung von pflanzlich hergestelltem Zucker durch die entsprechenden Mikroben allerdings in direkter Konkurrenz zur menschlichen Nahrungsmittelversorgung steht, soll aus CO2 und erneuerbarer Energie synthetisiertes Formiat (Ameisensäure) als alternativer Nährstoff nutzbar gemacht werden. Formiat fungiert als ein stabiler, leicht löslicher und sicher zu lagernder Energiespeicher, der als Ausgangsstoff mikrobieller Produktionen einen vielversprechenden Ansatz für eine nachhaltige Kreislaufwirtschaft eröffnet. Dieses Potenzial wurde bisher nicht realisiert, da es an einfach zu modifizierenden Mikroben, die Formiat effizient nutzen, mangelt. Zwecks mikrobieller Formiatnutzung wurden deshalb synthetische Stoffwechselwege entwickelt, die die Ein-Kohlenstoff Quelle deutlich effizienter als natürliche Alternativen in den Metabolismus einbringen. Die effizienteste Variante für die aerobe Formiat-Assimilation ist hierbei der reduktive Glycin-Stoffwechselweg. Während Letzterer zwar bereits erfolgreich in Mikroben eingebracht wurde, übertraf die Leistung dieser synthetischen Stämme trotz der theoretisch höheren Stoffwechseleffizienz nicht die des natürlichen Stoffwechsels. In dieser Arbeit entwickelte und optimierte ich zwei verschiedene synthetische Ein-Kohlenstoff-Fixierungswege in gramnegativen Bakterien, um die Grenzen der natürlichen CO2 Nutzung zu überschreiten. Das erste Kapitel untersuchte das Potenzial von Cupriavidus necator als vielversprechenden formatotrophen Wirt für die Produktion von Chemikalien mit hohem Mehrwert. Die Ameisensäuretoleranz von C. necator wurde getestet und ein Produktionsweg für Crotonat in einer modularen Weise etabliert. Schließlich wurde Bioprozessoptimierung genutzt, um Crotonat aus Formiat mit einem Titer von 148 mg/L zu produzieren. Im zweiten Kapitel integrierte ich den synthetischen reduktiven Glycinweg anstelle der nativen Formiatassimilierung chromosomal in C. necator und optimierte die Expressionsniveaus der beteiligten Enzyme und somit Wachstum des Stammes mit Hilfe eines transposonbasierten Selektionsansatzes. Die Kombination von randomisierter Insertionsmethodik und erzwungener Nutzung des Stoffwechselwegs für Wachstum auf Formiat ermöglichte hier die Selektion für bedingungsspezifisch optimale Expression des Stoffwechselweges, da eine höhere Operationsrate des Stoffwechselweges zu verbessertem Wachstum führte. Anschließend zeigte ich, dass meine optimierten synthetischen Stämme die Biomasseerträge des Calvin-Zyklus von C. necator auf Formiat übertrafen. Dies zeigte zum ersten Mal die bisher nur theoretisch prognostizierte Überlegenheit eines synthetischen Formiat-Assimilationsweges und damit der synthetischen Kohlenstofffixierung gegenüber natürlicher Kohlenstofffixierung. In Kapitel 3 entwickelte ich ein Segment des GED-Zyklus zur synthetischen CO2-Fixierung in Escherichia coli. Der GED-Zyklus ist eine Alternative zum Calvin-Zyklus, die im Gegensatz zu Letzterem keine ungewollte Aktivität mit Sauerstoff hat und somit energieeffizienter CO2 fixiert. Die einfache Architektur des Kreislaufs mit nur einer kritischen Reaktion macht ihn zu einem vielversprechenden Kandidaten für verbesserte Kohlenstofffixierung. Ich erzeugte einen Deletionsstamm, dessen Wachstum an besagte Reaktion, genauer die Carboxylierung mittels des GED-Segments, gekoppelt war. Die Fähigkeit des Stammes, CO2-abhängig zu wachsen, und die 13C-Tracer-Analyse bestätigten die Funktionalität des Weges in vivo. Im letzten Kapitel versuchte ich den GED-Zyklus auch in C. necator zu implementieren, da C. necator durch sein formatotrophes Wachstum potenziell ein vielversprechenderer Wirt sein könnte. Hierbei war das Wachstum des Calvin-Zyklus abhängigen Wildtyps, wie auch für den reduktiven Glycin-Weg, ein guter Referenzwert für den Vergleich mit den synthetischen Stämmen. Ich veränderte C. necator genetisch, sodass es das GED Substrat Xylose nutzt und zeigte, dass alle Enzyme für den Betrieb des Kohlenstofffixierungsweges in separierten Testeinheiten in vivo in C. necator funktional sind. Schließlich vergleiche ich meine Ergebnisse bezüglich der Entwicklung von linearer und zyklischer Ein-Kohlenstoff-Fixierung in zwei verschiedenen mikrobiellen Wirten. Es zeigt sich, dass der simplere lineare reduktive Glycinweg synthetische Formatotrophie von bisher unerschlossener Effizienz erlaubt, während sich die Realisierung komplexer autokatalytischer Kohlenstofffixierungszyklen als deutlich schwieriger erweist. Ich hebe die Vor- und Nachteile von C. necator als zukünftigem Plattformorganismus für synthetische Stoffwechselprozesse hervor und gebe einen Ausblick auf sein Potenzial für die Zukunft der C1-basierten Produktion.

T1 - Bacterial adaptation to venom in snakes and arachnida JF - Microbiology spectrum N2 - Notwithstanding their 3 to 5% mortality, the 2.7 million envenomation-related injuries occurring annually-predominantly across Africa, Asia, and Latin America-are also major causes of morbidity. Venom toxin-damaged tissue will develop infections in some 75% of envenomation victims, with E. faecalis being a common culprit of disease; however, such infections are generally considered to be independent of envenomation. Animal venoms are considered sterile sources of antimicrobial compounds with strong membrane-disrupting activity against multidrug-resistant bacteria. However, venomous bite wound infections are common in developing nations. Investigating the envenomation organ and venom microbiota of five snake and two spider species, we observed venom community structures that depend on the host venomous animal species and evidenced recovery of viable microorganisms from black-necked spitting cobra (Naja nigricollis) and Indian ornamental tarantula (Poecilotheria regalis) venoms. Among the bacterial isolates recovered from N. nigricollis, we identified two venom-resistant, novel sequence types of Enterococcus faecalis whose genomes feature 16 virulence genes, indicating infectious potential, and 45 additional genes, nearly half of which improve bacterial membrane integrity. Our findings challenge the dogma of venom sterility and indicate an increased primary infection risk in the clinical management of venomous animal bite wounds. IMPORTANCE Notwithstanding their 3 to 5% mortality, the 2.7 million envenomation-related injuries occurring annually-predominantly across Africa, Asia, and Latin America-are also major causes of morbidity. Venom toxin-damaged tissue will develop infections in some 75% of envenomation victims, with E. faecalis being a common culprit of disease; however, such infections are generally considered to be independent of envenomation. Here, we provide evidence on venom microbiota across snakes and arachnida and report on the convergent evolution mechanisms that can facilitate adaptation to black-necked cobra venom in two independent E. faecalis strains, easily misidentified by biochemical diagnostics. Therefore, since inoculation with viable and virulence gene-harboring bacteria can occur during envenomation, acute infection risk management following envenomation is warranted, particularly for immunocompromised and malnourished victims in resource-limited settings. These results shed light on how bacteria evolve for survival in one of the most extreme environments on Earth and how venomous bites must be also treated for infections.

Conventionally, phototrophic cyanobacteria are considered the major diazotrophs in aquatic environments. However, accumulating evidence indicates that diverse non-cyanobacterial diazotrophs (NCDs) inhabit a wide range of aquatic ecosystems, including temperate and polar latitudes, coastal environments and the deep ocean. NCDs are thus suspected to impact global nitrogen cycling decisively, yet their ecological and quantitative importance remain unknown. Here we review recent molecular and biogeochemical evidence demonstrating that pelagic NCDs inhabit and thrive especially on aggregates in diverse aquatic ecosystems. Aggregates are characterized by reduced-oxygen microzones, high C:N ratio (above Redfield) and high availability of labile carbon as compared to the ambient water. We argue that planktonic aggregates are important loci for energetically-expensive N-2 fixation by NCDs and propose a conceptual framework for aggregate-associated N-2 fixation. Future studies on aggregate-associated diazotrophy, using novel methodological approaches, are encouraged to address the ecological relevance of NCDs for nitrogen cycling in aquatic environments.

We consider one analytically solvable example (a generalized baker's map); two other examples, the Anosov-Mobius and the Chirikov-Mobius maps, which possess fractal attractor and repeller on a two-dimensional torus, are explored numerically. We demonstrate that although for these maps the stable and unstable directions are not orthogonal to each other, the relative Renyi and Kullback-Leibler dimensions as well as the mutual singularity spectra for the attractor and repeller can be well approximated under orthogonality assumption of two fractals.

A method to suppress this unwanted noise is to reduce the bandwidth of the measurement, but this approach is limited by the speed of the measurement and the width of the cantilever resonance, commonly defined through the quality factor Q. However, it has been shown that optomechanical resonances in interferometers might affect cantilever oscillations resulting in an effective quality factor Q(eff). When the laser power is sufficiently increased cantilever oscillations might even reach the regime of self-oscillation. In this self-oscillation state, the noise of the system is partially determined by the interaction with laser light far from equilibrium. Here, we show and discuss how tuning of laser power leads to nonlinear optomechanical effects that can dramatically increase the effective quality factor of the cantilever leading to out-of-equilibrium noise. We model the effects using a fourth order nonlinearity of the damping coefficient. Published under an exclusive license by AIP Publishing.

BT - female entrepreneurs and the gender pay gap JF - Journal of population economics N2 - We examine how the gender of business owners is related to the wages paid to female relative to male employees working in their firms. Using Finnish register data and employing firm fixed effects, we find that the gender pay gap is—starting from a gender pay gap of 11 to 12%—two to three percentage points lower for hourly wages in female-owned firms than in male-owned firms. Results are robust to how the wage is measured, as well as to various further robustness checks. More importantly, we find substantial differences between industries. While, for instance, in the manufacturing sector, the gender of the owner plays no role in the gender pay gap, in several service sector industries, like ICT or business services, no or a negligible gender pay gap can be found, but only when firms are led by female business owners. Businesses with male ownership maintain a gender pay gap of around 10% also in the latter industries. With increasing firm size, the influence of the gender of the owner, however, fades. In large firms, it seems that others—firm managers—determine wages and no differences in the pay gap are observed between male- and female-owned firms.

The species differ markedly in their ecosystem functions, thus shifts in their respective ranges are of global relevance. However, drivers of species distribution are not well understood, in part because paleoecological data at species level are lacking. This study tracks Larix species distribution in time and space using target enrichment on sedimentary ancient DNA extracts from eight lakes across Siberia. We discovered that Larix sibirica, presently dominating in western Siberia, likely migrated to its northern distribution area only in the Holocene at around 10,000 years before present (ka BP), and had a much wider eastern distribution around 33 ka BP. Samples dated to the Last Glacial Maximum (around 21 ka BP), consistently show genotypes of L. gmelinii. Our results suggest climate as a strong determinant of species distribution in Larix and provide temporal and spatial data for species projection in a changing climate. Using ancient sedimentary DNA from up to 50 kya, dramatic distributional shifts are documented in two dominant boreal larch species, likely guided by environmental changes suggesting climate as a strong determinant of species distribution.

BT - evidence from a survey experiment on attitudes toward maternal employment across contexts in Germany JF - Gender & society N2 - This paper examines the context dependency of attitudes toward maternal employment. We test three sets of factors that may affect these attitudes—economic benefits, normative obligations, and child-related consequences—by analyzing data from a unique survey experimental design implemented in a large-scale household panel survey in Germany (17,388 observations from 3,494 respondents). Our results show that the economic benefits associated with maternal employment are the most important predictor of attitudes supporting maternal employment. Moreover, we find that attitudes toward maternal employment vary by individual, household, and contextual characteristics (in particular, childcare quality). We interpret this variation as an indication that negative attitudes toward maternal employment do not necessarily reflect gender essentialism; rather, gender role attitudes are contingent upon the frames individuals have in mind.

These corporatization activities reflect an interplay between political agency and environmental pressures, including (changing) notions of state-market relations. This paper discusses two ideal-typed organizational models of corporatization: the state as a marketizer and the marketization of the state. Whereas the first emphasizes the role of political design and agency in corporatization, the second emphasizes the role of (actors in) the environment for corporatization. Both models are assessed across five corporatization episodes in Norway and Sweden, where we also demonstrate the interplay between political agency and environmental pressure.

Aims: This study aimed to determine impairments in planning skills of adults with PWS, in relation with their intellectual disabilities, as well as the influence of food compulsions on their performance. Methods and procedures: A modified version of the Zoo Map from the Behavioural Assessment of the Dysexecutive Syndrome was used in three groups: a group of adults with PWS in comparison with two groups both matched on chronological age, one with typical development (TD) and one with intellectual disability (ID). Outcomes and results: Compared to TD adults, both adults with PWS and ID showed increased planning time and lower raw scores on the planning task. The execution time and the number of errors were higher in the PWS group compared to the comparison groups. All three groups performed worse in the non-food condition only for number of errors and raw score. Conclusions and implications: Planning abilities were impaired in PWS adults. Results also showed that intellectual level plays a role in participants' performance. These findings are essential to understand the difficulties of people with PWS daily life.

T1 - Systematic review and meta-analysis of ex-post evaluations on the effectiveness of carbon pricing JF - Nature communications N2 - Today, more than 70 carbon pricing schemes have been implemented around the globe, but their contributions to emissions reductions remains a subject of heated debate in science and policy. Here we assess the effectiveness of carbon pricing in reducing emissions using a rigorous, machine-learning assisted systematic review and meta-analysis. Based on 483 effect sizes extracted from 80 causal ex-post evaluations across 21 carbon pricing schemes, we find that introducing a carbon price has yielded immediate and substantial emission reductions for at least 17 of these policies, despite the low level of prices in most instances. Statistically significant emissions reductions range between –5% to –21% across the schemes (–4% to –15% after correcting for publication bias). Our study highlights critical evidence gaps with regard to dozens of unevaluated carbon pricing schemes and the price elasticity of emissions reductions. More rigorous synthesis of carbon pricing and other climate policies is required across a range of outcomes to advance our understanding of “what works” and accelerate learning on climate solutions in science and policy.

Yet, one LIGO/Virgo observing run later, there has not yet been a second, secure identification of an electromagnetic counterpart. This is not surprising given that the localization uncertainties of events in LIGO and Virgo's third observing run, O3, were much larger than predicted. We explain this by showing that improvements in data analysis that now allow LIGO/Virgo to detect weaker and hence more poorly localized events have increased the overall number of detections, of which well-localized, gold-plated events make up a smaller proportion overall. We present simulations of the next two LIGO/Virgo/KAGRA observing runs, O4 and O5, that are grounded in the statistics of O3 public alerts. To illustrate the significant impact that the updated predictions can have, we study the follow-up strategy for the Zwicky Transient Facility. Realistic and timely forecasting of gravitational-wave localization accuracy is paramount given the large commitments of telescope time and the need to prioritize which events are followed up. We include a data release of our simulated localizations as a public proposal planning resource for astronomers.

The Iberian oak decline "Seca", related to Phytophthora infection, causes crown defoliation that may adversely affect ecosystem services (ESs). We aim to improve our understanding of how Seca-induced declines in crown foliation affect the provision of multiple ecosystem services from understory vegetation. We selected holm (Quercus ilex) and cork oak (Q. suber) trees in a Spanish oak woodland and evaluated three proxies of canopy effects. One proxy (crown defoliation) solely captured Seca-dependent effects, one proxy solely captured Seca-independent effects (tree dimensions such as diameter and height), while the third proxy (tree vigor) captured overall canopy effects. We then used the best-performing proxies to assess canopy effects on key ecosystem services (ESs) such as aboveground net primary production (ANPP), grass and legume biomass, species diversity, litter decomposition rates, and a combined index of ecosystem multifunctionality.
We found that both types of canopy effects (i.e. Seca-dependent and Seca-independent effects) were related, indicating that ANPP was disproportionally more affected by Seca when defoliated trees were large. Responses of other ESs were mostly not significant, although lower species diversity was found under trees with intermediate vigor. Our results underline that a Seca-related decline in canopy density triggered a homogenization of ecosystem service delivery on the ecosystem scale. The ecosystem functions (EFs) under trees of low vigor are similar to that in adjacent open microsites indicating that the presence of vigorous (i.e. old and vital) trees is critical for maintaining EFs at a landscape level. Our results also highlight the importance of quantifying not only defoliation but also tree dimensions as both factors jointly and interactively modify canopy effects on ecosystem multifunctionality.

In humans, these capabilities are thought to be related to our ability to perceive our body in space, sensing the location of our limbs during movement, being aware of other objects and agents, and controlling our body parts to interact with them intentionally. Toward the next generation of robots with bio-inspired capacities, in this paper, we first review the developmental processes of underlying mechanisms of these abilities: The sensory representations of body schema, peripersonal space, and the active self in humans. Second, we provide a survey of robotics models of these sensory representations and robotics models of the self; and we compare these models with the human counterparts. Finally, we analyze what is missing from these robotics models and propose a theoretical computational framework, which aims to allow the emergence of the sense of self in artificial agents by developing sensory representations through self-exploration.

Traditional methods using conventional microscopy require expert knowledge, are time-intensive and not well-suited for automated high throughput. Multispectral imaging flow cytometry (MIFC) allows measurement of up to 5000 particles per second from a fluid suspension and can simultaneously capture up to 12 images of every single particle for brightfield and different spectral ranges, with up to 60x magnification. The high throughput of MIFC has high potential for increasing the amount and accuracy of environmental monitoring, such as for plant-pollinator interactions, fossil samples, air, water or food quality that currently rely on manual microscopic methods. Automated recognition of particles and cells is also possible, when MIFC is combined with deep-learning computational techniques. Furthermore, various fluorescence dyes can be used to stain specific parts of the cell to highlight physiological and chemical features including: vitality of pollen or algae, allergen content of individual pollen, surface chemical composition (carbohydrate coating) of cells, DNA- or enzyme-activity staining. Here, we outline the great potential for MIFC in environmental research for a variety of research fields and focal organisms. In addition, we provide best practice recommendations.

The development and implementation of innovative geoscientific software is currently evolving towards a sustainable and efficient development by integrating models of different aspects of the Earth system. This will set the foundation for a future digital twin of the Earth. The codification and update of this software require great effort from research groups and therefore, it needs to be preserved for its reuse by future generations of geoscientists. Here, we report on Geo-Soft-CoRe, a Geoscientific Software & Code Repository, hosted at the archive DIGITAL.CSIC. This is an open source, multidisciplinary and multiscale collection of software and code developed to analyze different aspects of the Earth system, encompassing tools to: 1) analyze climate variability; 2) assess hazards, and 3) characterize the structure and dynamics of the solid Earth. Due to the broad range of applications of these software packages, this collection is useful not only for basic research in Earth science, but also for applied research and educational purposes, reducing the gap between the geosciences and the society. By providing each software and code with a permanent identifier (DOI), we ensure its self-sustainability and accomplish the FAIR (Findable, Accessible, Interoperable and Reusable) principles. Therefore, we aim for a more transparent science, transferring knowledge in an easier way to the geoscience community, and encouraging an integrated use of computational infrastructure.

T1 - Same soil, different climate: Crop model intercomparison on translocated lysimeters JF - Vadose zone journal N2 - Crop model intercomparison studies have mostly focused on the assessment of predictive capabilities for crop development using weather and basic soil data from the same location. Still challenging is the model performance when considering complex interrelations between soil and crop dynamics under a changing climate. The objective of this study was to test the agronomic crop and environmental flux-related performance of a set of crop models. The aim was to predict weighing lysimeter-based crop (i.e., agronomic) and water-related flux or state data (i.e., environmental) obtained for the same soil monoliths that were taken from their original environment and translocated to regions with different climatic conditions, after model calibration at the original site. Eleven models were deployed in the study. The lysimeter data (2014-2018) were from the Dedelow (Dd), Bad Lauchstadt (BL), and Selhausen (Se) sites of the TERENO (TERrestrial ENvironmental Observatories) SOILCan network. Soil monoliths from Dd were transferred to the drier and warmer BL site and the wetter and warmer Se site, which allowed a comparison of similar soil and crop under varying climatic conditions. The model parameters were calibrated using an identical set of crop- and soil-related data from Dd. Environmental fluxes and crop growth of Dd soil were predicted for conditions at BL and Se sites using the calibrated models. The comparison of predicted and measured data of Dd lysimeters at BL and Se revealed differences among models. At site BL, the crop models predicted agronomic and environmental components similarly well. Model performance values indicate that the environmental components at site Se were better predicted than agronomic ones. The multi-model mean was for most observations the better predictor compared with those of individual models. For Se site conditions, crop models failed to predict site-specific crop development indicating that climatic conditions (i.e., heat stress) were outside the range of variation in the data sets considered for model calibration. For improving predictive ability of crop models (i.e., productivity and fluxes), more attention should be paid to soil-related data (i.e., water fluxes and system states) when simulating soil-crop-climate interrelations in changing climatic conditions.

T1 - Dihydroceramide- and ceramide-profiling provides insights into human cardiometabolic disease etiology JF - Nature communications N2 - Metabolic alterations precede cardiometabolic disease onset. Here we present ceramide- and dihydroceramide-profiling data from a nested case-cohort (type 2 diabetes [T2D, n = 775]; cardiovascular disease [CVD, n = 551]; random subcohort [n = 1137]) in the prospective EPIC-Potsdam study. We apply the novel NetCoupler-algorithm to link a data-driven (dihydro)ceramide network to T2D and CVD risk. Controlling for confounding by other (dihydro)ceramides, ceramides C18:0 and C22:0 and dihydroceramides C20:0 and C22:2 are associated with higher and ceramide C20:0 and dihydroceramide C26:1 with lower T2D risk. Ceramide C16:0 and dihydroceramide C22:2 are associated with higher CVD risk. Genome-wide association studies and Mendelian randomization analyses support a role of ceramide C22:0 in T2D etiology. Our results also suggest that (dh)ceramides partly mediate the putative adverse effect of high red meat consumption and benefits of coffee consumption on T2D risk. Thus, (dihydro)ceramides may play a critical role in linking genetic predisposition and dietary habits to cardiometabolic disease risk.

T1 - “Ick bin een Berlina” BT - dialect proficiency impacts a robot’s trustworthiness and competence evaluation JF - Frontiers in robotics and AI N2 - Background: Robots are increasingly used as interaction partners with humans. Social robots are designed to follow expected behavioral norms when engaging with humans and are available with different voices and even accents. Some studies suggest that people prefer robots to speak in the user’s dialect, while others indicate a preference for different dialects. Methods: Our study examined the impact of the Berlin dialect on perceived trustworthiness and competence of a robot. One hundred and twenty German native speakers (Mage = 32 years, SD = 12 years) watched an online video featuring a NAO robot speaking either in the Berlin dialect or standard German and assessed its trustworthiness and competence. Results: We found a positive relationship between participants’ self-reported Berlin dialect proficiency and trustworthiness in the dialect-speaking robot. Only when controlled for demographic factors, there was a positive association between participants’ dialect proficiency, dialect performance and their assessment of robot’s competence for the standard German-speaking robot. Participants’ age, gender, length of residency in Berlin, and device used to respond also influenced assessments. Finally, the robot’s competence positively predicted its trustworthiness. Discussion: Our results inform the design of social robots and emphasize the importance of device control in online experiments.

BT - an empirical analysis JF - Politische Vierteljahresschrift N2 - Germany’s relatively stable party system faces a new left-authoritarian challenger: Sahra Wagenknecht’s Bündnis Sahra Wagenknecht (BSW) party. First polls indicate that for the BSW, election results above 10% are within reach. While Wagenknecht’s positions in economic and cultural terms have already been discussed, this article elaborates on another highly relevant feature of Wagenknecht, namely her populist communication. Exploring Wagenknecht’s and BSW’s populist appeal helps us to understand why the party is said to also have potential among seemingly different voter groups coming from the far right Alternative for Germany (AfD) and far left Die Linke, which share high levels of populist attitudes. To analyse the role that populist communication plays for Wagenknecht and the BSW, this article combines quantitative and qualitative methods. The quantitative analysis covers all speeches (10,000) and press releases (19,000) published by Die Linke members of Parliament (MPs; 2005–2023). The results show that Wagenknecht is the (former) Die Linke MP with the highest share of populist communication. Furthermore, she was also able to convince a group of populist MPs to join the BSW. The article closes with a qualitative analysis of BSW’s manifesto that reveals how populist framing plays a major role in this document, in which the political and economic elites are accused of working against the interest of “the majority”. Based on this analysis, the classification of the BSW as a populist party seems to be appropriate. N2 - Die langjährige Stabilität des deutschen Parteiensystems wird aktuell durch eine neue links-konservative Partei herausgefordert: Bündnis Sahra Wagenknecht (BSW). Erste Umfragen deuten an, dass das BSW bundesweit bis zu 10 % der Stimmen gewinnen könnte. Die Einordnung als links-konservativ oder in Anlehnung an die englische Literatur links-autoritär wurde bereits medial intensiv diskutiert. Weniger Beachtung hat bislang die populistische Kommunikation von Wagenknecht gefunden. Die populistische Ansprache durch das BSW kann bei der Beantwortung der Frage behilflich sein, warum das BSW scheinbar gegensätzliche Gruppen wie Wähler:innen der Linken und der AfD gleichzeitig ansprechen kann, da populistische Einstellungen unter den Wähler:innen beider Parteien weit verbreitet sind. Der vorliegende Beitrag analysiert die Rolle der populistischen Kommunikation von Wagenknecht und dem BSW mithilfe qualitativer und quantitativer Methoden. Dazu wurden zunächst alle Reden (ca. 10.000) und alle Pressemitteilungen (ca. 19.000) aller Linken-Bundestagsabgeordneten der gesamten parlamentarischen Lebensdauer der Fraktion (2005–2023) untersucht. Die Ergebnisse dieser quantitativen Analyse zeigen, dass Wagenknecht unter den Linken-Abgeordneten mit Abstand am häufigsten populistische Kommunikationselemente einsetzte und sie ebenso in der Lage war, einige der populistischsten Abgeordneten zum BSW-Beitritt zu überreden. Der Artikel schließt mit einer qualitativen Auswertung der populistischen Rhetorik im BSW-Parteiprogramm. Es wird deutlich, dass hier insbesondere die Kritik an der Politik- und Wirtschaftselite eine wichtige Rolle spielt. Diese Elitenkritik wird mit einem starken Bevölkerungsbezug kombiniert, der beispielsweise in der Ansprache der „Mehrheit“ deutlich wird. Insgesamt erscheint damit die Klassifizierung als populistische Partei gerechtfertigt.

We find that more populated and denser grid cells are more exposed to pollution. However, across urban areas, exposure increases with cities’ population size but decreases with density. Moreover, the population effect is driven mostly by population commuting to core cities rather than the core city population itself. We analyse heterogeneity by geography and income levels. A counterfactual simulation shows that exposure could fall by up to 40% if population size were equalized across all cities within countries, but the relocation of population from large to small cities that maximizes welfare would be small.

In this article, we argue that it also holds in another domain, nominalization. In languages that show overt nominalization of VPs, one word order is routinely unattested, namely, a head-initial VP with a suffixal nominalizer. This typological gap can be accounted for by the Final-over-Final Condition, if we allow it to hold within mixed extended projections. This view also makes correct predictions about agentive nominalizations and nominalized serial verb constructions.

T1 - Motivational profiles across domains and academic choices within Eccles et al.’s situated expectancy BT - value theoretical framework JF - Developmental psychology N2 - This longitudinal person-centered study aimed to identify profiles of subjective task values and ability self-concepts of adolescents in the domain of mathematics, English, biology, and physics in Grades 10 and 12. We were interested in gendered changes of profile membership, and in relations between profile membership and educational and occupational outcomes in adulthood. Data were drawn from the Michigan Study of Adolescent and Adult Life Transitions. We focused on students who participated in the data collection in Grades 10 and 12 (N = 911; 56.1% female; M-age = 16.49, SD = .63; 91.2% European American, 4.6% African American, and 2.1% other ethnic groups such as Hispanic, Asian, Native American). Data on subsequent college majors were assessed 2, 6, and 10 years after finishing high school and data on occupational outcomes was assessed up to 22 years after high school. Using Latent Profile Analyses, our findings revealed five profiles in grade 10 and four profiles in grade 12, which were meaningfully related to student gender. Latent Transition Analyses showed that motivational beliefs became more hierarchical over time. Gendered changes in profile membership occurred, with boys experiencing a process of specialization into mathematics domains. We were also able to show that gender-specific intraindividual hierarchies of motivational beliefs were related to gender-specific specialization processes in adolescence and to subsequent gendered choices throughout the life course.

A1 - Aseev, Nikita A1 - Krupp, Norbert T1 - Spectra of Saturn's proton belts revealed JF - Icarus N2 - Saturn is permanently surrounded by 6 discrete proton radiation belts that are rigidly separated by the orbits of its inner moons and dense rings. These radiation belts are ideal environments to study the details of radial diffusion and the CRAND source process, yet progress has been hindered by the fact that the energy spectra are not known with certainty: Reanalysis of the response functions of the LEMMS instrument on-board the Cassini orbiter has shown that measurements of less than or similar to 10 MeV protons may be easily contaminated by greater than or similar to 10 MeV protons and that many available measurements characterize a very broad energy range, so that the calculation of an energy-resolved spectrum is not as straightforward as previously assumed. Here we use forward modeling of the measurements based on the instrument response and combine this technique where useful with numerical modeling of the proton belt physics in order to determine Saturn's spectra with higher certainty. We find significant proton intensities up to approximate to 1 GeV. While earlier studies reported on proton spectra roughly following a power law with exponent approximate to -2, our more advanced analysis shows harder spectra with exponent approximate to -1. The observed spectra provide independent confirmation that Saturn's proton belts are sourced by CRAND and are consistent with the provided protons being subsequently cooled in the tenuous gas originating from Saturn or Enceladus. The intensities at Saturn are found to be lower than at Jupiter and Earth, which is also consistent with the source of Saturn being exclusively CRAND, while the other planets can draw from additional processes. Our new spectra can be used in the future to further our understanding of Saturn's proton belts and the respective physical processes that occur at other magnetized planets in general. Also, the spectra have applications for several topics of planetary science, such as space weathering of Saturn's moons and rings, and can be useful to constrain properties of the main rings through their production of secondary particles.

B N2 - The martensitic transformation is a fundamental physical phenomenon at the origin of important industrial applications. However, the underlying microscopic mechanism, which is of critical importance to explain the outstanding mechanical properties of martensitic materials, is still not fully understood. This is because for most martensitic materials the transformation is a fast process that makes in situ studies extremely challenging. Noble solids krypton and xenon undergo a progressive pressure-induced face-centered cubic (fcc) to hexagonal close-packed (hcp) martensitic transition with a very wide coexistence domain. Here, we took advantage of this unique feature to study the detailed transformation progress at the atomic level by employing in situ x-ray diffraction and absorption spectroscopy. We evidenced a four-stage pathway and suggest that the lattice mismatch between the fcc and hcp forms plays a key role in the generation of strain. We also determined precisely the effect of the transformation on the compression behavior of these materials.

The band shift to low wavenumbers is explained by strong O3-H center dot center dot center dot O5 hydrogen bridge bonding. Applying the regression equation to natural B-[4]-bearing tourmaline from the Koralpe (Austria) reproduces the EMPA-derived value perfectly [EMPA: 0.67(12) B-[4] pfu vs. Raman: 0.66(13) B-[4] pfu]. This demonstrates that Raman spectroscopy provides a fast and easy-to-use tool for the quantification of tetrahedral boron in tourmaline. The knowledge of the amount of tetrahedral boron in tourmaline has important implications for the better understanding and modeling of B-isotope fractionation between tourmaline and fluid/melt, widely used as a tracer of mass transfer processes.

Dabei gehört es doch inzwischen zum Selbstverständnis moderner Universitäten, öffentlich zu erklären, woran in ihren Räumen geforscht wird, sich in gesellschaftliche Diskurse einzubringen und ihre Erkenntnisse zügig in die Praxis zu überführen. Die Universität Potsdam hat diese Transferaufgaben neben Lehre und Forschung als dritte Säule installiert und ihrem Gebäude damit noch mehr Stabilität verliehen. Seit Jahren gehört sie im nationalen Vergleich zu den erfolgreichsten Hochschulen, wenn es darum geht, Start-ups zu fördern und aus der Forschung heraus Unternehmen zu gründen: In diesem Magazin berichten wir von der Potassco Solutions GmbH des Informatikers Torsten Schaub, der mit seinem KI-System Clingo komplexe Optimierungsprobleme in Betrieben löst. Oder von der SEQSTANT GmbH, die mit innovativer Diagnostik Erreger von Atemwegserkrankungen in Echtzeit bestimmen kann. Wir zeigen aber auch, wie Forschungsteams mit der Industrie kooperieren, zum Beispiel mit der K-UTEC im thüringischen Sondershausen, um mit wissenschaftlichem Knowhow dazu beizutragen, dass dort in Produktionsabfällen kein wertvolles Lithium verloren geht. Richtet sich der Technologietransfer vor allem an die Wirtschaft, so hilft der Wissenstransfer der gesamten Gesellschaft. Besonders stark ist die Universität Potsdam hier in der Bildung, denn mit ihren Lehramtsabsolventen schickt sie auch gleich den aktuellen Stand der Unterrichtsforschung in die Schulpraxis. Immer häufiger zieht dabei die Digitalisierung in die Klassenzimmer ein. Wie das gut gelingen kann, ist in diesem Magazin zu lesen. Zudem erklären wir, was die Sportwissenschaft zur Therapie von Depressionen beitragen kann oder wie die Umweltforschung das Risikomanagement in von Hochwasser bedrohten Regionen verbessern will. Ob in öffentlichen Verwaltungen oder politischen Institutionen – überall ist wissenschaftliche Expertise gefragt. Wir zeigen das am Beispiel von Frauke Brosius-Gersdorf, die als Juristin die Bundesregierung zur Regulierung des Schwangerschaftsabbruchs berät. Der kürzeste Weg des Wissens aus der Universität in die Praxis führt zweifelsohne über die Alumni, die als Fach- und Führungskräfte im Land und darüber hinaus wirksam werden. Dass dieser Weg schon während des Studiums beginnen kann, beweisen die vielen studentischen Initiativen, die hier zu Wort kommen. Sie alle scheuen nicht das Rampenlicht: ob bei Science Slams auf den Bühnen im Land Brandenburg, bei den TEDx-Talks im Hans Otto Theater, beim Kunst-Rundgang in der Potsdamer Waschhaus-Arena oder mit englischsprachigem Schauspiel an der Uni. Öffentlich in Erscheinung treten, neue Formen finden, um Wissen in die Breite der Bevölkerung zu tragen – auch das gehört zum Transfer. Genau wie dieses Magazin.

Have you taken part in a video conference at work, used or programmed a database? Have you paid with your smartphone on the way home, listened to a podcast, or extended the lending of books you borrowed from the library? And in the evening, have you filled out your tax return application on ELSTER.de on your tablet, shopped online, or paid invoices before you were tempted to watch a series on a streaming platform? Our lives are entirely digitalized. These changes make many things faster, easier, and more efficient. But keeping pace with these changes demands a lot from us, and not everyone succeeds. There are people who prefer to go to the bank to make a transfer, leave the programming to the experts, send their tax return by mail, and only use their smartphone to make phone calls. They don’t want to keep pace, or maybe they can’t. They haven’t learned these things. Others, younger people, grow up as “digital natives” surrounded by digital devices, tools, and processes. But does that mean they really know how to use them? Or do they also need digital education? But what does successful digital education actually look like? Does it teach us how to use a tablet, how to google properly, and how to write Excel spreadsheets? Perhaps it’s about more than that. It’s about understanding the comprehensive change that has been taking hold of our world since it was broken down into digital ones and zeros and rebuilt virtually. But how do we learn to live in a world of digitality – with all that it entails, and to our benefit? For the new issue of “Portal Wissen”, we looked around at the university and interviewed researchers about the role that the connection between digitalization and learning plays in the research of various disciplines. We spoke to Katharina Scheiter, Professor of Digital Education, about the future of German schools and had several experts show us examples of how digital tools can improve learning in schools. We also talked to computer science and agricultural researchers about how even experienced farmers can still learn a lot about their land and their work thanks to digital tools. We spoke to educational researchers who are using big data to analyze how boys and girls learn and what the possible causes for differences are. Education and political scientist Nina Kolleck, on the other hand, looks at education against the backdrop of globalization and relies on the analysis of large amounts of social media data. Of course, we don’t lose sight of the diversity of research at the University of Potsdam. We learn, for example, what alternatives to antibiotics could soon be available. This magazine also looks at stress and how it makes us ill as well as the research into sustainable ore extraction. A new feature of our magazine is a whole series of shorter articles that invite you to browse and read: from research news and photographic insights into laboratories to simple explanations of complex phenomena and outlooks into the wider world of research to a small scientific utopia and a personal thanks to research. All this in the name of education, of course. Enjoy your read!

T1 - Portal = Welt retten N2 - Fragen beantworten, Unbekanntes erklären, Rätsel lösen – und die gewonnenen Erkenntnisse zum Nutzen der Menschheit einsetzen: Das treibt Wissenschaftler*innen auf der ganzen Welt an. Forschung ist keine Geheimwissenschaft, die im stillen Kämmerlein passiert. Sie dient im besten Fall allen. Sie funktioniert voraussetzungsfrei und ergebnisoffen, und gerade deshalb können Forschungsergebnisse notwendige Innovationen, Transformation oder Umdenken fördern und auf diese Weise die Welt verändern. Zum Besseren, so die Hoffnung. Für diese Ausgabe der „Portal“ haben wir Universitätspräsident Prof. Oliver Günther, Ph.D. und die Ökologin Prof. Dr. Damaris Zurell gefragt, ob Wissenschaft die Welt retten kann. Sie sind sich einig: Forschung trägt dazu bei, dass viele Menschen ein lebenswertes und erfülltes Leben führen können. Sie betonen aber auch: Wissenschaft kann das nicht allein erreichen, für echte Veränderungen braucht es Politik, Wirtschaft und Gesellschaft. Wie wichtig es ist, dass wissenschaftliche Erkenntnisse uns zum Handeln bewegen, davon erzählen auch die vielen anderen Geschichten in diesem Heft. Denn in Potsdam tragen nicht nur Wissenschaftler*innen, sondern auch Studierende und Beschäftigte in Technik und Verwaltung dazu bei, die Universität, ihr Umfeld oder „die Welt da draußen“ Stück für Stück besser zu machen. Jonathan Schorsch zum Beispiel, Professor für Jüdische Religions- und Geistesgeschichte, hat den „Grünen Sabbat“ ins Leben gerufen: einen Tag in der Woche, an dem wir der Erde – und uns selbst – eine kleine Pause gönnen. Der Jurist Andreas Zimmermann berichtet von einem Verfahren vor dem Internationalen Gerichtshof zum Klimawandel, an dem er als Forscher beteiligt ist, und seine Kollegin Dr. Anna von Rebay kämpft als Anwältin für die Rechte des Meeres vor Ausbeutung und Verschmutzung. Der Voltaire-Preisträger Gera Gizaw erzählt von einem Flüchtlingscamp in Kenia aus die Geschichten der Menschen dort und der Medizinethiker Robert Ranisch zeigt, wie die Pflege künftig für noch mehr Wohl sorgen kann. Hochschulangehörige engagieren sich für den Bildungsaufstieg von Menschen aus nicht-akademischen Familien und der Student Tobias Föhl kämpft bei ONE gegen Armut auf der Welt. Mitarbeiter aus der Musikwissenschaft verlängern das Leben von alten Möbeln und Musikinstrumenten, Studierende arbeiten mit Jugendfeuerwehren aus der Region zusammen. Der Better World Award wirft ein Licht auf innovative Ideen, die schnellstmöglich ihren Weg aus der Uni in die Öffentlichkeit finden sollten. Wie wichtig die Kommunikation wissenschaftlicher Erkenntnisse ist, zeigen Julia Wandt und Kristin Küter, die Menschen aus dem Wissenschaftsbetrieb beraten, die Anfeindungen ausgesetzt sind. Denn damit es vorangeht, damit Lösungen für Probleme dieser Welt gefunden werden, darf eines nicht geschehen: dass die Forschung verstummt.

We hypothesize that differences in islet gene expression alternative splicing which can contribute to altered protein function also participate in islet dysfunction. RNA sequencing (RNAseq) data from islets of obese diabetes-resistant and diabetes-susceptible mice were analyzed for alternative splicing and its putative genetic and epigenetic modulators. We focused on the expression levels of chromatin modifiers and SNPs in regulatory sequences. We identified alternative splicing events in islets of diabetes-susceptible mice amongst others in genes linked to insulin secretion, endocytosis or ubiquitin-mediated proteolysis pathways. The expression pattern of 54 histones and chromatin modifiers, which may modulate splicing, were markedly downregulated in islets of diabetic animals. Furthermore, diabetes-susceptible mice carry SNPs in RNA-binding protein motifs and in splice sites potentially responsible for alternative splicing events. They also exhibit a larger exon skipping rate, e.g., in the diabetes gene Abcc8, which might affect protein function. Expression of the neuronal splicing factor Srrm4 which mediates inclusion of microexons in mRNA transcripts was markedly lower in islets of diabetes-prone compared to diabetes-resistant mice, correlating with a preferential skipping of SRRM4 target exons. The repression of Srrm4 expression is presumably mediated via a higher expression of miR-326-3p and miR-3547-3p in islets of diabetic mice. Thus, our study suggests that an altered splicing pattern in islets of diabetes-susceptible mice may contribute to an elevated T2D risk.

We use the commercial code FracMan (Golder Associates) that enables studying hydro-mechanical coupled processes in fractured media in three dimensions combining the finite element method with a discrete fracture network. The software is used to simulate fluid pressure perturbation at fractures during hydraulic stimulation. Our numerical simulation shows that pressure history matching can be obtained by partitioning the treatment into separate phases. This results in adjusted stress-aperture relationships. The evolution of aperture adjustment implies that the stimulation mechanism could be a combination of hydraulic fracturing and shearing. The simulated extent of the 0.01 MPa overpressure contour at the end of the treatment equals to similar to 180 m around the injection point.

Such acquired thermotolerance can be maintained for several days under normal growth conditions, and can create a heat stress memory. We recently demonstrated that plastid-localized small heat shock protein 21 ( HSP21) is a key component of heat stress memory in Arabidopsis thaliana. A sustained high abundance of HSP21 during the heat stress recovery phase extends heat stress memory. The level of HSP21 is negatively controlled by plastid-localized metalloprotease FtsH6 during heat stress recovery. Here, we demonstrate that autophagy, a cellular recycling mechanism, exerts additional control over HSP21 degradation. Genetic and chemical disruption of both metalloprotease activity and autophagy trigger superior HSP21 accumulation, thereby improving memory. Furthermore, we provide evidence that autophagy cargo receptor ATG8-INTERACTING PROTEIN1 (ATI1) is associated with heat stress memory. ATI1 bodies co-localize with both autophagosomes and HSP21, and their abundance and transport to the vacuole increase during heat stress recovery. Together, our results provide new insights into the module for control of the regulation of heat stress memory, in which two distinct protein degradation pathways act in concert to degrade HSP21, thereby enabling cells to recover from the heat stress effect at the cost of reducing the heat stress memory.
