TY - JOUR A1 - Andree, Kerstin A1 - Ihde, Sven A1 - Weske, Mathias A1 - Pufahl, Luise T1 - An exception handling framework for case management JF - Software and Systems Modeling N2 - In order to achieve their business goals, organizations heavily rely on the operational excellence of their business processes. In traditional scenarios, business processes are usually well-structured, clearly specifying when and how certain tasks have to be executed. Flexible and knowledge-intensive processes are gathering momentum, where a knowledge worker drives the execution of a process case and determines the exact process path at runtime. In the case of an exception, the knowledge worker decides on an appropriate handling. While there is initial work on exception handling in well-structured business processes, exceptions in case management have not been sufficiently researched. This paper proposes an exception handling framework for stage-oriented case management languages, namely Guard Stage Milestone Model, Case Management Model and Notation, and Fragment-based Case Management. The effectiveness of the framework is evaluated with two real-world use cases showing that it covers all relevant exceptions and proposed handling strategies.

Prior research has demonstrated that under uncertainty individuals with high IU display difficulties in updating learned threat associations to safety associations. Importantly, recent research has shown that providing contingency instructions about threat and safety contingencies (i.e. reducing uncertainty) to individuals with high IU promotes the updating of learned threat associations to safety associations. Here we aimed to conceptually replicate IU and contingency instruction-based effects by conducting a secondary analysis of self-reported IU, ratings, skin conductance, and functional magnetic resonance imaging (fMRI) data recorded during uninstructed/instructed blocks of threat acquisition and threat extinction training (n = 48). Generally, no significant associations were observed between self-reported IU and differential responding to learned threat and safety cues for any measure during uninstructed/instructed blocks of threat acquisition and threat extinction training. There was some tentative evidence that higher IU was associated with greater ratings of unpleasantness and arousal to the safety cue after the experiment and greater skin conductance response to the safety cue during extinction generally. Potential explanations for these null effects and directions for future research are discussed.

T1 - An encounter-based approach for restricted diffusion with a gradient drift JF - Journal of physics : A, Mathematical and theoretical N2 - We develop an encounter-based approach for describing restricted diffusion with a gradient drift toward a partially reactive boundary. For this purpose, we introduce an extension of the Dirichlet-to-Neumann operator and use its eigenbasis to derive a spectral decomposition for the full propagator, i.e. the joint probability density function for the particle position and its boundary local time. This is the central quantity that determines various characteristics of diffusion-influenced reactions such as conventional propagators, survival probability, first-passage time distribution, boundary local time distribution, and reaction rate. As an illustration, we investigate the impact of a constant drift onto the boundary local time for restricted diffusion on an interval. More generally, this approach accesses how external forces may influence the statistics of encounters of a diffusing particle with the reactive boundary.

The PADs are fitted with a combination of the first, third and fifth sine harmonics. The resulting equation resolves all PAD types found in the outer radiation belt (pancake, flat-top, butterfly and cap PADs) and can be analytically integrated to derive omnidirectional flux. We introduce a two-step modeling procedure that for the first time ensures a continuous dependence on L, magnetic local time and activity, parametrized by the solar wind dynamic pressure. We propose two methods to reconstruct equatorial electron flux using the model. The first approach requires two uni-directional flux observations and is applicable to low-PA data. The second method can be used to reconstruct the full equatorial PADs from a single uni- or omnidirectional measurement at off-equatorial latitudes. The model can be used for converting the long-term data sets of electron fluxes to phase space density in terms of adiabatic invariants, for physics-based modeling in the form of boundary conditions, and for data assimilation purposes.

Yet, intracellular fluxes cannot be measured directly but are estimated with metabolic flux analysis (MFA), which relies on the patterns of isotope labeling of metabolites in the network. The application of MFA also requires a stoichiometric model with atom mappings that are currently not available for the majority of large-scale metabolic network models, particularly of plants. While automated approaches such as the Reaction Decoder Toolkit (RDT) can produce atom mappings for individual reactions, tracing the flow of individual atoms of the entire reactions across a metabolic model remains challenging. Here we establish an automated workflow to obtain reliable atom mappings for large-scale metabolic models by refining the outcome of RDT, and apply the workflow to metabolic models of Arabidopsis thaliana. We demonstrate the accuracy of RDT through a comparative analysis with atom mappings from a large database of biochemical reactions, MetaCyc. We further show the utility of our automated workflow by simulating N-15 isotope enrichment and identifying nitrogen (N)-containing metabolites which show enrichment patterns that are informative for flux estimation in future N-15-MFA studies of A. thaliana. The automated workflow established in this study can be readily expanded to other species for which metabolic models have been established and the resulting atom mappings will facilitate MFA and graph-theoretic structural analyses with large-scale metabolic networks.

As the measurement of high energy neutrons is not so easy, alternative particles can be considered for such purpose. Among them, muons are particles created from the same cascade of primary cosmic-ray fluxes that generate neutrons at the ground. In addition, they can be easily detected by small and relatively inexpensive detectors. For these reasons they could provide a suitable local alternative to incoming corrections based on remote neutron monitor data. The reported measurements demonstrated that muon detection system can detect incoming cosmic-ray variations locally. Furthermore the precision of this measurement technique is considered adequate for many CRNS applications.

In this volume, contributors analyze why the allegorical first-person romance embedded itself in the vernacular literature of Western Europe and remained popular for more than two centuries. The editors identify and discuss three predominant forms within this family: debate poetry, dream allegories, and autobiographies. Contributors offer textual analyses of key works from late medieval German, French, Italian, and Iberian literature, with discussion of developments in England, as well. Allegory and the Poetic Self offers a sophisticated, theoretically current discussion of relevant literature. This exploration of medieval “I” narratives offers insights not just into the premodern period but also into Western literature’s subsequent traditions of self-analysis and identity crafting through storytelling.

A1 - Mädlow, Wolfgang T1 - All-season space use by non-native resident Mandarin Ducks (Aix galericulata) in northeastern Germany JF - Journal of ornithology / publ. by Deutsche Ornithologen-Gesellschaft N2 - Patterns of space use are often subject to large temporal and individual-level variation, due to seasonality in behaviour and environmental conditions as well as age- or sex-specific needs. Especially in temperate regions, seasonality likely influences space use even in non-migratory birds. In waterfowl of the family Anatidae, however, few studies have analyzed space use of the same individuals across the full annual cycle. We used a resident population of Mandarin Ducks (Aix galericulata) in northeast Germany to study their year-round space use in relation to season, sex, and age. We marked 172 birds with colour rings and surveyed relevant water bodies for re-encounters for several years. As space-use patterns we derived home ranges from minimum convex polygons and the number of water bodies used by individual birds. Our analysis revealed that individuals shifted their space use between seasons, in particular extending their home ranges during the non-breeding season. Between years, in contrast, birds tended to show season-specific site fidelity. Sex differences were apparent during both breeding and non-breeding season, males consistently having larger home ranges and using slightly more water bodies. No difference was found between first-year and adult birds. Our study demonstrates that mark-resighting can provide valuable information about space use in species with suitable behaviour and readily accessible habitat. In such cases, it may be a valid alternative to more expensive GPS-tracking or short-term manual radio telemetry, particularly within citizen-science projects. N2 - Raumnutzungsmuster von Vögeln zeigen häufig große zeitliche und individuelle Variationen in Abhängigkeit vom saisonalen Verhalten und von Umweltbedingungen, aber auch alters- und geschlechtsspezifischen Ansprüchen. In gemäßigten Klimazonen können jahreszeitliche Einflussfaktoren die Raumnutzung auch von nicht ziehenden Arten bestimmen. Für Entenvögel (Anatidae) liegen bisher jedoch nur wenige Studien vor, die die Raumnutzung von Individuen über den gesamten Jahresverlauf hinweg betrachten. Wir untersuchten die ganzjährige Raumnutzung einer Standvogel-Population der Mandarinente (Aix galericulata) in Abhängigkeit von Jahreszeit, Geschlecht und Alter der Vögel. Wir markierten 172 Vögel mit Farbringen und kontrollierten mehrere Jahre lang die relevanten Gewässer, um Ringablesungen zu erzielen. Zur Analyse der Raumnutzung ermittelten wir Minimum-Convex-Polygone und die Anzahl der von den einzelnen Individuen genutzten Gewässer. Unsere Auswertung zeigte, dass die von den Vögeln genutzten Aktionsräume sich mit den Jahreszeiten veränderten. Insbesondere vergrößerte sich das besuchte Gebiet außerhalb der Brutzeit. Beim Vergleich mehrerer Jahre tendierten die Vögel zu einer saisonspezifischen Gebietstreue. Geschlechterunterschiede zeigten sich sowohl innerhalb als auch außerhalb der Brutzeit, wobei die Männchen stets größere Gebiete und eine größere Zahl an Gewässern nutzten. Zwischen Vögeln im ersten Lebensjahr und Adulten wurden keine Unterschiede gefunden. Unsere Untersuchung zeigt, dass Farbberingungsprogramme wertvolle Informationen zur Raumnutzung bei Arten liefern können, deren Verhalten dafür geeignet ist und die in gut zugänglichen Lebensräumen vorkommen. In diesen Fällen kann die Farbberingung eine geeignete Alternative zur teureren GPS- oder manuellen Telemetrie sein, vor allem wenn die vereinte Kraft von Amateurornithologen in die Untersuchungen einbezogen werden kann.

P. Lovecraft’s oeuvre abounds with stereotypes of the racialized poor. As scholars have noted, Lovecraft’s work turns those he viewed as ‘Others’ into ‘aliens.’ Poor people of color (as opposed to the orderly White rural population and White working class) in Lovecraft’s stories are foreign, diseased, and criminal, and they threaten social and cosmic orders as they are in league with a nebulous entity that waits to wreak indescribable havoc. This chapter analyzes three ‘Lovecraftian’ novels published in 2016 - Cassandra Khaw’s Hammers on Bone,Victor LaValle’s The Ballad of Black Tom, and Matt Ruff’s Lovecraft Country. These works elucidate the connection of Trump’s 2016 rhetoric in campaign and presidential speeches and the White supremacist imagery used by Lovecraft. In these novels, the racialized poor have a special connection to an astronomical, evil entity à la Lovecraft. As carriers of numinous genes or parasitic entities (literally having ‘an alien within’) they become empowered. They thus occupy a pivotal position in forestalling or bringing about the destruction of societal order; that is, of White supremacy. Exploring the alleged risk posed by this ‘underclass,’ these works seem to foretell current representations of protesters as ‘riotous mobs’ that threaten the body politic Trump sought to make great (and White) again.

N2 - Alexander von Humboldt and the Frisian naturalist Ulrich Jasper Seetzen met in 1789 during their studies at the University of Göttingen. They shared common scientific interests in natural history. Later Seetzen, like Humboldt, conducted a multidisciplinary expedition which was meant to encompass the Middle East, Arabia and, as a final destination, central Africa which he intended to traverse as the first European traveller. The expedition came to an abrupt end in Yemen. This short description of Seetzen’s life and work focuses on his early relation to Humboldt. The paper centers around an investigation of a manuscript written by Seetzen which turns out to be an excerpt of a so far unknown letter by the 21-year-old Humboldt featuring a short observation abstract of his journey to the North Sea island Helgoland in 1790.

ED - Strecker, Manfred ED - Schneider, Simon T1 - Alexander von Humboldt BT - multiperspective approaches N2 - This book aims to view and to understand Alexander von Humboldt from different perspectives and in varying disciplinary contexts. His contributions addressed numerous topics in the earth but also life sciences—spanning from geo-botany, climatology, paleontology, oceanography, mineralogy, resources, and hydrogeology to links between the environmental impact of humans, erosion, and climate change. From the very beginning, he paved the way for a modern, integrated earth system science approach to decipher, characterize, and model the different forcing factors and their feedback mechanisms. It becomes obvious that Humboldt’s holistic approach is far beyond simple description and empiric data collection. As documented and analyzed in the different texts of this volume, he combines observation and analysis with emotions and subjective perceptions in a very affectionate way. However, this publication does not intend to add another encyclopedic text compilation but to observe and critically analyze this unique personality´s relevance in a modern context, particularly in discussing environmental and social key issues in the twenty-first century.

(DVGS) N2 - Objective of the study: The long-term use of telemedical programs depends not only on their effectiveness, but also on patient acceptance and satisfaction. The effectiveness of telemedical exercise therapy for patients after implantation of a total knee or hip prosthesis and subsequent rehabilitation has already been examined in a randomized controlled study. This article focuses on the patient's acceptance and usage behaviour with regard to the tele-rehabilitation system. Methodology: 48 patients (53 +/- 7 years; 26 women; 35 hip/13 knee TEP) were questioned after a three-month telemedical movement therapy using the Telehealth Usability Questionnaire (TUQ) to determine the acceptance of the technology. The questionnaire consisted of 21 items (seven-point Likert scale) in six scales (e. g. usefulness, quality of interactions, reliability). System-specific questions were summarized on an additional scale. The results were presented as a percentage of the scale (100 estimates complete agreement). The usage behaviour was examined using system-generated process data for training and integrated voice/text messages. Results: The TUQ scales "Usefulness" (Mdn 95.2) and "Ease of use and learnability" (Mdn 92.9) were rated the highest, while "Reliability" (Mdn 57.1) and "Quality of interactions" ( Mdn 71.4) showed the lowest levels. The system-specific scale was placed in the upper quartile (Mdn 85.7). In the first week, 39 patients (81%) and in the second 45 patients (94%) performed at least one training exercise with the system. The proportion of active patients (>= 1 exercise/week) decreased in the further course to 75% (n=36) in the 7th week and 48% (n=23) in the 12th week. The system communication options were initially used frequently after the start of therapy: in the first week, 42 patients (88%) sent messages, 47 patients (98%) received messages from their therapist respectively. In week 7, 9 (19%) and 13 (27%) patients sent/received messages via the system respectively. Conclusion: Most of the patients perceived telemedical movement therapy as useful and user-friendly and seemed to be largely satisfied with the system. This proved to be well suited for short-term use of 6 to 8 weeks following subsequent rehabilitation. N2 - Ziel der Studie: Die langfristige Nutzung telemedizinischer Angebote hängt nicht nur von deren Wirksamkeit, sondern auch von der Akzeptanz und Zufriedenheit der Patienten ab. Für eine telemedizinische Bewegungstherapie für Patienten nach Implantation einer Knie- oder Hüft-Totalendoprothese und erfolgter Anschlussrehabilitation wurde die Wirksamkeit bereits in einer randomisiert kontrollierten Studie untersucht. Dieser Beitrag fokussiert die Akzeptanz und das Nutzungsverhalten der Patienten hinsichtlich des eingesetzten telerehabilitativen Systems. Methodik: Zur Erfassung der Technikakzeptanz wurden 48 Patienten (53±7 Jahre; 26 Frauen; 35 Hüft-/13 Knie-TEP) im Anschluss an eine dreimonatige telemedizinische Bewegungstherapie mittels des Telehealth Usability Questionnaire befragt. Der Fragebogen besteht aus 21 Items (siebenstufige Likert-Skala) in sechs Skalen (z. B. Nützlichkeit, Qualität der Interaktionen, Verlässlichkeit). In einer zusätzlichen Skala wurden systemspezifische Fragen zusammengefasst. Die Ergebnisse wurden als Skalenprozent (100 ≙ vollkommene Zustimmung) dargestellt. Das Nutzungsverhalten wurde anhand systemgenerierter Prozessdaten zum Training sowie zu integrierten Sprach-/Textnachrichten untersucht. Ergebnisse: Die TUQ-Skalen „Nützlichkeit“ (Mdn 95,2) sowie „Benutzerfreundlichkeit und Erlernbarkeit“ (Mdn 92,9) wurden am höchsten bewertet, während die „Verlässlichkeit“ (Mdn 57,1) und „Qualität der Interaktionen“ (Mdn 71,4) die geringsten Ausprägungen zeigten. Die systemspezifische Skala wurde im oberen Quartil eingeordnet (Mdn 85,7). In der ersten Woche führten 39 Patienten (81%), in der zweiten 45 Patienten (94%) mindestens eine Trainingsübung mit dem System durch. Der Anteil aktiver Patienten (≥1 Übung/Woche) reduzierte sich im weiteren Verlauf auf 75% (n=36) in der 7. Woche und 48% (n=23) in der 12. Woche. Die systemeigenen Kommunikationsmöglichkeiten wurden nach Therapiestart zunächst häufig genutzt: in der ersten Woche sendeten 42 Patienten (88%) Nachrichten, 47 Patienten (98%) erhielten Nachrichten von ihrem Therapeuten. In der 7. Woche sendeten/erhielten 9 (19%) bzw. 13 (27%) Patienten Nachrichten über das System. Schlussfolgerung: Die Patienten nahmen die telemedizinische Bewegungstherapie überwiegend als nützlich und benutzerfreundlich wahr und schienen im Wesentlichen mit dem System zufrieden, das sich damit für den kurzfristigen Einsatz von 6 bis 8 Wochen im Anschluss an eine Anschlussrehabilitation als gut geeignet zeigte.

However, population decline was reported over the last decades and is still ongoing. While agricultural intensification is a major driver of the rapid loss of pollinating species, transition zones between arable fields and forest or grassland patches, i.e., agricultural buffer zones, are frequently mentioned as suitable mitigation measures to support wild bee populations and other pollinator species. Despite the reported general positive effect, it remains unclear which amount of buffer zones is needed to ensure a sustainable and permanent impact for enhancing bee diversity and abundance. To address this question at a pollinator community level, we implemented a process-based, spatially explicit simulation model of functional bee diversity dynamics in an agricultural landscape. More specifically, we introduced a variable amount of agricultural buffer zones (ABZs) at the transition of arable to grassland, or arable to forest patches to analyze the impact on bee functional diversity and functional richness. We focused our study on solitary bees in a typical agricultural area in the Northeast of Germany. Our results showed positive effects with at least 25% of virtually implemented agricultural buffer zones. However, higher amounts of ABZs of at least 75% should be considered to ensure a sufficient increase in Shannon diversity and decrease in quasi-extinction risks. These high amounts of ABZs represent effective conservation measures to safeguard the stability of pollination services provided by solitary bee species. As the model structure can be easily adapted to other mobile species in agricultural landscapes, our community approach offers the chance to compare the effectiveness of conservation measures also for other pollinator communities in future.

Vielmehr gewinnen Ansätze und Methoden des New Work im öffentlichen Sektor angesichts der sich stetig ändernden und dynamischen Arbeitswelt eine immer größere Bedeutung. Umso mehr besteht die Notwendigkeit, sich in der Verwaltung agil aufzustellen. Unter Agilität wird hierbei die Fähigkeit einer Organisation verstanden, sich schnell verändernden Rahmenbedingungen flexibel und dynamisch anzupassen. Im Fokus dieser Arbeit steht der Einfluss von Agilität auf die Führungskräfte-Mitarbeiter-Beziehung. Mittels einer halbstandardisierten Online-Befragung im Landesamt für Flüchtlingsangelegenheiten und im Bezirksamt Neukölln von Berlin wird zunächst der vorliegende Agilitätsgrad mit dem Fokus auf agile Organisationsstrukturen, agile Organisationskultur und agile Führung ermittelt und sodann anhand der Qualität der dyadischen Arbeitsbeziehung von Führungskraft und Mitarbeiter (LMX-Qualität) überprüft, inwiefern die agile Arbeitsweise im Vergleich zu einer nicht-agilen Arbeitsumgebung die Beziehung beeinflusst. Im Ergebnis der Untersuchung zeigt sich, dass ein positiver Zusammenhang zwischen Agilität und der Führungskräfte-Mitarbeiter-Beziehung besteht. Es stellt sich in beiden Ämtern ein mäßig bis starker Agilitätsgrad heraus, wobei besonders agile Führungseigenschaften zu den wesentlichen Faktoren zählen, die eine hochqualitative Beziehung begünstigen. Während im Bezirksamt ein Zusammenhang zwischen Agilität und hoher LMX-Qualität ermittelt wurde, konnte dieser nicht für die untersuchte Stichprobe des Landesamts festgestellt werden. Dennoch ließ sich in beiden Behörden ein positiver Einfluss von Agilität auf zumindest die Entwicklung einer erfolgreichen Führungskräfte-Mitarbeiter-Beziehung erfassen. N2 - Continuous complex challenges and tasks are no longer solvable with the classic structures and methods of public administration. Rather concepts of New Work are gaining importance due to the dynamic work environment in the public sector. This leads to the necessity of an agile transformation in public administration. Agility in organizations is understood to be the ability to adapt to rapidly changing conditions in the work environment. The following paper focuses on the influence of agility on the Leader-Member-Exchange (LMX). Using a semi-standard online poll, the degree of agility with an emphasis on agile organizational structures, agile organizational culture, and agile leadership is analyzed in the State Office for Refugees Affairs and District Office Neukölln of Berlin. Furthermore, relationships between leaders and subordinates in an agile environment and relationships in a non-agile environment are compared through the lens of the quality of Leader-Member-Exchange (LMX-Quality). The results show a significant influence of agility on Leader-Member-Exchange. In both Offices a moderate to high degree of agility is found. Particularly, agile leadership characteristics encourage high-quality relationships. Whereas a correlation between agility and high LMX-Quality is identified in the District Office Neukölln, this result could not be observed in the State Office of Refugees Affairs. However, the influence of agility on at least the development of a positive and successful relationship is established in both Offices.

Dabei werden zum einen bestehende Forschungslücken des Einflusses von Bevölkerungsdichte auf die Luftqualität geschlossen und zum anderen innovative Politikmaßnahmen im Verkehrsbereich untersucht, die Ballungsräume nachhaltiger gestalten sollen. Im Zentrum der Betrachtungen stehen Luftverschmutzung, Staus und Verkehrsunfälle, die für Fragen der allgemeinen Wohlfahrt bedeutend sind und erhebliche Kostenfaktoren für urbanes Leben darstellen. Von ihnen ist ein beträchtlicher Anteil der Weltbevölkerung betroffen. Während im Jahr 2018 bereits 55% der Menschen weltweit in Städten lebten, soll dieser Anteil bis zum Jahr 2050 ungefähr 68% betragen. Die vier in sich geschlossenen Kapitel dieser Arbeit lassen sich in zwei Abschnitte aufteilen: In den Kapiteln 2 und 3 werden neue kausale Erkenntnisse über das komplexe Zusammenspiel von städtischen Strukturen und Luftverschmutzung erbracht. Kapitel 4 und 5 untersuchen anschließend politische Maßnahmen zur Förderung nicht-motorisierter Verkehrsmittel und deren Einfluss auf Luftqualität sowie Staugeschehen und Verkehrsunfälle. N2 - The present dissertation conducts empirical research on the relationship between urban life and its economic costs, especially for the environment. On the one hand, existing gaps in research on the influence of population density on air quality are closed and, on the other hand, innovative policy measures in the transport sector are examined that are intended to make metropolitan areas more sustainable. The focus is on air pollution, congestion and traffic accidents, which are important for general welfare issues and represent significant cost factors for urban life. They affect a significant proportion of the world's population. While 55% of the world's people already lived in cities in 2018, this share is expected to reach approximately 68% by 2050. The four self-contained chapters of this thesis can be divided into two sections: Chapters 2 and 3 provide new causal insights into the complex interplay between urban structures and air pollution. Chapters 4 and 5 then examine policy measures to promote non-motorised transport and their influence on air quality as well as congestion and traffic accidents.

Here we asked how restriction-related changes influence cognitive performance and how age, perceived loneliness, depressiveness and affectedness by restrictions contribute to these effects. 51 Germans completed three assessments of an online based study during the first lockdown in Germany (April 2020), a month later, and during the beginning of the second lockdown (November 2020). Participants completed nine online cognitive tasks of the MyBrainTraining and online questionnaires about their perceived strain and impact on lifestyle factors by the situation (affectedness), perceived loneliness, depressiveness as well as subjective cognitive performance. The results suggested a possible negative impact of depressiveness and affectedness on objective cognitive performance within the course of the lockdown. The younger the participants, the more pronounced these effects were. Loneliness and depressiveness moreover contributed to a worse evaluation of subjective cognition. In addition, especially younger individuals reported increased distress. As important educational and social input has partly been scarce during this pandemic and mental health problems have increased, future research should also assess cognitive long-term consequences.

In many cases, bioturbation and sedimentary mixing affect the proxy time-series and the age-depth relationship. While idealized models of bioturbation exist, they usually assume homogeneous mixing, thus that a single sample is representative for the sediment layer it is sampled from. However, it is largely unknown to which extent this assumption holds for sediments used for paleoclimate reconstructions. To shed light on 1) the age-depth relationship and its full uncertainty, 2) the magnitude of mixing processes affecting the downcore proxy variations, and 3) the representativity of the discrete sample for the sediment layer, we designed and performed a case study on South China Sea sediment material which was collected using a box corer and which covers the last glacial cycle. Using the radiocarbon content of foraminiferal tests as a tracer of time, we characterize the spatial age-heterogeneity of sediments in a three-dimensional setup. In total, 118 radiocarbon measurements were performed on defined small- and large-volume bulk samples ( similar to 200 specimens each) to investigate the horizontal heterogeneity of the sediment. Additionally, replicated measurements on small numbers of specimens (10 x 5 specimens) were performed to assess the heterogeneity within a sample volume. Visual assessment of X-ray images and a quantitative assessment of the mixing strength show typical mixing from bioturbation corresponding to around 10 cm mixing depth. Notably, our 3D radiocarbon distribution reveals that the horizontal heterogeneity (up to 1,250 years), contributing to the age uncertainty, is several times larger than the typically assumed radiocarbon based age-model error (single errors up to 250 years). Furthermore, the assumption of a perfectly bioturbated layer with no mixing underneath is not met. Our analysis further demonstrates that the age-heterogeneity might be a function of sample size; smaller samples might contain single features from the incomplete mixing and are thus less representative than larger samples. We provide suggestions for future studies, optimal sampling strategies for quantitative paleoclimate reconstructions and realistic uncertainty in age models, as well as discuss possible implications for the interpretation of paleoclimate records.

Mobile people of African descent use this term to address their own lived realities creatively, which often includes countering stereotypical notions of being African. Afropolitan practices are enormously heterogeneous and malleable, which constitutes its strengths and, at the same time, creates tensions. This book traces the theoretical beginnings of Afropolitanism and moves on to explore Afropolitan practices in London and Berlin. Afropolitanism can take different forms, such as that of an identity, a political and ethical stance, a dead–end road, networks, a collective self–care practice or a strategic label. In spite of the harsh criticism, Afropolitanism is attractive for people to deal with the meanings of Africa and Africanness, questions of belonging, equal rights and opportunities. While not a unitary project, the vast variety of Afropolitan practices provide approaches to contemporary political problems in Europe and beyond. In this book, Afropolitan practices are read against the specific context of German and British colonial histories and structures of racism, the histories of Black Europeans, and contemporary right–wing resurgence in Germany and England, respectively.

Addressing norm collisions as a particular type of norm dynamics, we ask if and how advocacy coalitions and the constellations between them bring such norm collisions to the fore. Norm collisions surface in situations in which actors claim that two or more norms are incompatible with each other, promoting different, even opposing, behavioural choices. We examine the effect of advocacy coalition constellations (ACC) on the activation and varying evolution of norm collisions in three issue areas: international drug control, human trafficking, and child labour. These areas have a legally codified prohibitive regime in common. At the same time, they differ with regard to the specific ACC present. Exploiting this variation, we generate insights into how power asymmetries and other characteristics of ACC affect norm collisions across our three issue areas.

Against this background, this study focuses on developmental change in the use of adverbial clause-combining constructions in Turkish-German bilingual students’ oral and written text production. It illustrates the use of non-finite constructions and some unique alternative strategies to express adverbial relations with authentic examples in Turkish and German. The findings contribute to a better understanding of how bilingual competencies vary in expressing adverbial relations depending on language contact and extra-linguistic factors.

A membrane/separator is a critical component of ZABs, with substantial implications for battery performance and stability, particularly in the case of a battery in solid state format, which has captured increased attention in recent years. In this review, recent advances as well as insight into the architecture of polymeric membrane/separators for ZABs including porous polymer separators (PPSs), gel polymer electrolytes (GPEs), solid polymer electrolytes (SPEs) and anion exchange membranes (AEMs) are discussed.

The specific focus lies on the investigation of the feasibility and technology limits of customized silica AWG devices for high resolution near-infrared spectroscopy. In a series of theoretical and experimental studies, AWG devices of varying geometry, foot-print and spectral resolution are constructed, simulated using a combination of a numerical beam propagation method and Fraunhofer diffraction and fabricated devices are characterized with respect to transmission efficiency, spectral resolution and polarization sensitivity. The impact of effective index non-uniformities on the performance of high-resolution AWG devices is studied numerically. Characterization results of fabricated devices are used to extrapolate the technology limits of the silica platform. The important issues of waveguide birefringence and defocus aberration are discussed theoretically and addressed experimentally by selection of an appropriate aberration-minimizing anastigmatic AWG layout structure. The drawbacks of the anastigmatic AWG geometry are discussed theoretically. From the results of the experimental studies, it is concluded that fabrication-related phase errors and waveguide birefringence are the primary limiting factors for the growth of AWG spectral resolution. It is shown that, without post-processing, the spectral resolving power is phase-error-limited to R < 40, 000 and, in the case of unpolarized light, birefringence-limited to R < 30, 000 in the AWG devices presented in this work. Necessary measures, such as special waveguide geometries and post-fabrication phase error correction are proposed for future designs. The elimination of defocus aberration using an anastigmatic AWG geometry is successfully demonstrated in experiment. Finally, a novel, non-planar dispersive in-fibre waveguide structure is proposed, discussed and studied theoretically. N2 - Das Ziel der vorliegenden Arbeit ist die Untersuchung von Arrayed Waveguide Gratings (AWGs) auf SiO2-Basis im Kontext von Anwendungen in der Astronomie. Der besondere Fokus liegt auf der Untersuchung der Machbarkeit und der technologischen Grenzen von spezialisierten AWGs für die hochauflösende Nahinfrarot-Spektroskopie. In einer Reihe von theoretischen und experimentellen Studien werden AWGs unterschiedlicher Geometrie, Größe und spektraler Auflösung konstruiert, unter Verwendung einer numerischen Beam-Propagation-Methode (BPM) und Fraunhofer-Beugung simuliert und hinsichtlich Effizienz, spektraler Auflösung und Polarisationsempfindlichkeit charakterisiert. Der Einfluss von Variationen des effektiven Brechungsindex auf die Leistung von hochauflösenden AWGs wird numerisch untersucht. Mit hergestellten AWGs gewonnene Messergebnisse werden verwendet, um die technologischen Grenzen der SiO2-Plattform zu extrapolieren. Die relevanten Probleme der Polarisationsempfindlichkeit und der in kanonischen Rowland-Geometrien auftretenden Defokusaberration werden theoretisch diskutiert und experimentell durch die Auswahl einer geeigneten aberrationsminimierenden AWG-Struktur angegangen. Die Nachteile anastigmatischer AWGs werden theoretisch diskutiert. Aus den Ergebnissen der experimentellen Studien wird geschlossen, dass herstellungsbedingte Phasenfehler und Wellenleiter-Doppelbrechung die primären begrenzenden Faktoren für die Erhöhung der AWG-Spektralauflösung sind. Es wird gezeigt, dass das spektrale Auflösungsvermögen der in dieser Arbeit präsentierten AWGs ohne Phasenfehlerkorrektur auf R < 40, 000 und durch Doppelbrechung auf R < 30, 000 im Fall unpolarisierten Lichtes begrenzt ist. Notwendige Maßnahmen wie spezielle Wellenleitergeometrien und Phasenfehlerkorrektur nach der Herstellung werden für zukünftige AWG-Designs empfohlen. Die Eliminierung von Defokussierungsfehlern unter Verwendung einer anastigmatischen AWG-Geometrie wird erfolgreich im Experiment demonstriert. Schließlich wird eine neuartige, in eine optische Faser eingebettete, nicht-planare dispersive Wellenleiterstruktur vorgeschlagen, diskutiert und theoretisch untersucht.

Objective This study aims to identify which barrier factors impede the usage of wearables for assessing individual risk scores for health insurances, despite its technological feasibility, and to rank these barriers according to their relevance. Methods To reach these goals, we conduct a ranking-type Delphi study with the following three stages. First, we collected possible barrier factors from a panel of 16 experts and consolidated them to a list of 11 barrier categories. Second, the panel was asked to rank them regarding their relevance. Third, to enhance the panel consensus, the ranking was revealed to the experts, who were then asked to re-rank the barriers. Results The results suggest that regulation is the most important barrier. Other relevant barriers are false or inaccurate measurements and application errors caused by the users. Additionally, insurers could lack the required technological competence to use the wearable data appropriately. Conclusion A wider use of wearables and health apps could be achieved through regulatory modifications, especially regarding privacy issues. Even after assuring stricter regulations, users’ privacy concerns could partly remain, if the data exchange between wearables manufacturers, health app providers, and health insurers does not become more transparent.

Narrowing this gap in the literature, the present study focused on examining the moderating effects of emotional reactions (i.e., guilt, sadness, anger) after not intervening in cyberbullying on the longitudinal relationship between cyberbullying bystanding and health issues (i.e., subjective health complaints, suicidal ideation, non-suicidal self-harm). Participants were 1,067 adolescents between 12 and 15 years old included in this study (M-age = 13.67; 51% girls). The findings showed a positive association between Time 1 cyberbullying bystanding and Time 2 health issues. Guilt moderated the positive relationships among Time 1 cyberbullying bystanding, Time 2 subjective health complaints, suicidal ideation, and non-suicidal self-harm. Time 1 sadness also moderated the relationship between Time 1 cyberbullying bystanding and Time 2 suicidal ideation and non-suicidal self-harm. However, anger did not moderate any of the associations.

T1 - Adjusting agricultural emissions for trade matters for climate change mitigation JF - Nature Communications N2 - Reducing greenhouse gas emissions in food systems is becoming more challenging as food is increasingly consumed away from producer regions, highlighting the need to consider emissions embodied in trade in agricultural emissions accounting. To address this, our study explores recent trends in trade-adjusted agricultural emissions of food items at the global, regional, and national levels. We find that emissions are largely dependent on a country’s consumption patterns and their agricultural emission intensities relative to their trading partners’. The absolute differences between the production-based and trade-adjusted emissions accounting approaches are especially apparent for major agricultural exporters and importers and where large shares of emission-intensive items such as ruminant meat, milk products and rice are involved. In relative terms, some low-income and emerging and developing economies with consumption of high emission intensity food products show large differences between approaches. Similar trends are also found under various specifications that account for trade and re-exports differently. These findings could serve as an important element towards constructing national emissions reduction targets that consider trading partners, leading to more effective emissions reductions overall.

T1 - Ad hoc learning of peptide fragmentation from mass spectra enables an interpretable detection of phosphorylated and cross-linked peptides JF - Nature machine intelligence N2 - Fragmentation of peptides leaves characteristic patterns in mass spectrometry data, which can be used to identify protein sequences, but this method is challenging for mutated or modified sequences for which limited information exist. Altenburg et al. use an ad hoc learning approach to learn relevant patterns directly from unannotated fragmentation spectra. Mass spectrometry-based proteomics provides a holistic snapshot of the entire protein set of living cells on a molecular level. Currently, only a few deep learning approaches exist that involve peptide fragmentation spectra, which represent partial sequence information of proteins. Commonly, these approaches lack the ability to characterize less studied or even unknown patterns in spectra because of their use of explicit domain knowledge. Here, to elevate unrestricted learning from spectra, we introduce 'ad hoc learning of fragmentation' (AHLF), a deep learning model that is end-to-end trained on 19.2 million spectra from several phosphoproteomic datasets. AHLF is interpretable, and we show that peak-level feature importance values and pairwise interactions between peaks are in line with corresponding peptide fragments. We demonstrate our approach by detecting post-translational modifications, specifically protein phosphorylation based on only the fragmentation spectrum without a database search. AHLF increases the area under the receiver operating characteristic curve (AUC) by an average of 9.4% on recent phosphoproteomic data compared with the current state of the art on this task. Furthermore, use of AHLF in rescoring search results increases the number of phosphopeptide identifications by a margin of up to 15.1% at a constant false discovery rate. To show the broad applicability of AHLF, we use transfer learning to also detect cross-linked peptides, as used in protein structure analysis, with an AUC of up to 94%.

Smaller particles, like virions, antibodies, enzymes, and even dye molecules can be immobilized by DEP as well. In principle, it was shown that enzymes are active after immobilization by DEP, but no quantification of the retained activity was reported so far. In this study, the activity of the enzyme horseradish peroxidase (HRP) is quantified after immobilization by DEP. For this, HRP is immobilized on regular arrays of titanium nitride ring electrodes of 500 nm diameter and 20 nm widths. The activity of HRP on the electrode chip is measured with a limit of detection of 60 fg HRP by observing the enzymatic turnover of Amplex Red and H2O2 to fluorescent resorufin by fluorescence microscopy. The initial activity of the permanently immobilized HRP equals up to 45% of the activity that can be expected for an ideal monolayer of HRP molecules on all electrodes of the array. Localization of the immobilizate on the electrodes is accomplished by staining with the fluorescent product of the enzyme reaction. The high residual activity of enzymes after AC field induced immobilization shows the method's suitability for biosensing and research applications.

B. Wortstellungsinformationen, prosodische und lexikalische Mittel im Sprachverständnis korrekt interpretieren. N2 - Successful communication is often explored by people throughout their life courses. To effectively transfer one’s own information to others, people employ various linguistic tools, such as word order information, prosodic cues, and lexical choices. The exploration of these linguistic cues is known as the study of information structure (IS). Moreover, an important issue in the language acquisition of children is the investigation of how they acquire IS. This thesis seeks to improve our understanding of how children acquire different tools (i.e., prosodical cues, syntactical cues, and the focus particle only) of focus marking in a cross linguistic perspective. In the first study, following Szendrői and her colleagues (2017)- the sentence-picture verification task- was performed to investigate whether three- to five-year-old Mandarin-speaking children as well as Mandarin-speaking adults could apply prosodic information to recognize focus in sentences. More, in the second study, not only Mandarin-speaking adults and Mandarin-speaking children but also German-speaking adults and German-speaking children were included to confirm the assumption that children could have adult-like performance in understanding sentence focus by identifying language specific cues in their mother tongue from early onwards. In this study, the same paradigm- the sentence-picture verification task- as in the first study was employed together with the eye-tracking method. Finally, in the last study, an issue of whether five-year-old Mandarin-speaking children could understand the pre-subject only sentence was carried out and again whether prosodic information would help them to better understand this kind of sentences. The overall results seem to suggest that Mandarin-speaking children from early onwards could make use of the specific linguistic cues in their ambient language. That is, in Mandarin, a Topic-prominent and tone language, the word order information plays a more important rule than the prosodic information and even three-year-old Mandarin-speaking children could follow the word order information. More, although it seems that German-speaking children could follow the prosodic information, they did not have the adult-like performance in the object-accented condition. A feasible reason for this result is that there are more possibilities of marking focus in German, such as flexible word order, prosodic information, focus particles, and thus it would take longer time for German-speaking children to manage these linguistic tools. Another important empirical finding regarding the syntactically-marked focus in German is that it seems that the cleft construction is not a valid focus construction and this result corroborates with the previous observations (Dufter, 2009). Further, eye-tracking method did help to uncover how the parser direct their attention for recognizing focus. In the final study, it is showed that with explicit verbal context Mandarin-speaking children could understand the pre-subject only sentence and the study brought a better understanding of the acquisition of the focus particle- only with the Mandarin-speaking children.

A paper-and-pencil questionnaire was given to parents of pediatric patients (<21 years) during the routine check-ups. The questionnaire contains self-constructed items assessing the frequency of healthcare appointments and cancellations, remote healthcare, and satisfaction with healthcare. In total, 905 parents participated in the T1D-sample, 175 in the obesity-sample, and 786 in the JIA-sample. In general, satisfaction with healthcare (scale: 0–10; 10 reflecting the highest satisfaction) was quite high (median values: T1D 10, JIA 10, obesity 8.5). The proportion of children and adolescents with canceled appointments was relatively small (T1D 14.1%, JIA 11.1%, obesity 20%), with a median of 1 missed appointment, respectively. Only a few parents (T1D 8.6%; obesity 13.1%; JIA 5%) reported obstacles regarding health services during the pandemic. To conclude, it seems that access to healthcare was largely preserved for children and adolescents with chronic health conditions during the COVID-19 pandemic in Germany.
