The relative influence of these two factors on nanoscale chemistry is strongly debated. This article discusses the temperature dependence of the dimerization of 4-nitrothiophenol (4-NTP) into 4,4′-dimercaptoazobenzene (DMAB) adsorbed on gold nanoflowers by Surface-Enhanced Raman Scattering (SERS). Raman thermometry shows a significant optical heating of the particles. The ratio of the Stokes and the anti-Stokes Raman signal moreover demonstrates that the molecular temperature during the reaction rises beyond the average crystal lattice temperature of the plasmonic particles. The product bands have an even higher temperature than reactant bands, which suggests that the reaction proceeds preferentially at thermal hot spots. In addition, kinetic measurements of the reaction during external heating of the reaction environment yield a considerable rise of the reaction rate with temperature. Despite this significant heating effects, a comparison of SERS spectra recorded after heating the sample by an external heater to spectra recorded after prolonged illumination shows that the reaction is strictly photo-driven. While in both cases the temperature increase is comparable, the dimerization occurs only in the presence of light. Intensity dependent measurements at fixed temperatures confirm this finding.

As they shift from products to (service) solutions, manufacturing companies pursue new strategic direction, inter alia, by extensively employing service business development activities. The objective of this dissertation is to investigate the considerable (re-)emerging stream of service business development by providing vital insights for academia and management into important focus areas that have hardly, if at all, been (empirically) investigated in the existing literature before. Therefore, these findings can be vital to informing a differentiation in current and future marketing strategies in business practice. First of all, this dissertation focuses on the extent to which service business development is transposed into business practice. Because scarce empirical-quantitative research has studied the current state of service business development across various industry and market sectors, this study analyzes a unique, manually collected dataset of 266 (product and service) business development activities. In so doing, this investigation contributes to literature by presenting a comprehensive, industry-wide status quo and trend report of service business development in practice. Furthermore, given the surprisingly limited scientific attention paid to the question of how service business development is strategically configured and further applied to different environmental circumstances, this dissertation provides comprehensive theoretical and practical implications by analyzing in detail a sample of 137 service business developments of 66 product-oriented companies. Lastly, manufacturers are recognizing that service-oriented value creation is moving toward a more collaborative process of co-creation as a promising measure to achieve competitive advantage, and even more as an appropriate response to complex business environments. Thus, an increasing number of companies around the world have recently introduced business models related to access-based services such as car-, scooter-, and bike-sharing systems. But despite the considerable advantages of access-based services as an alternative to ownership, these companies are now seeing that consumer adoption and (re-)usage rates remain insufficient. Owing to the lack of general and cross-national scientific knowledge, the purpose of this dissertation continues to explore which factors impede diffusion of related service business development activities from a consumer perspective and what kind of differences can be established between countries. Consequently, with a total of 1,443 participants, a cross-national survey was carried out in three countries, i.e., the United States, Germany, and China, to measure a vast number of different adoption barriers derived from a developed integrated framework that combines established theories within innovation and adoption behavior research.

The method allows to study attenuation within the source region of earthquake swarms or aftershocks at depth, independent of wave path and attenuation between source region and surface station. We exploit the high-frequency slope of phase spectra using multitaper spectral estimates. The method is tested using simulated full wave-field seismograms affected by recorded noise and finite source rupture. The synthetic tests verify the approach and show that solutions are independent of focal mechanisms but also show that seismic noise may broaden the scatter of results. We apply the event couple spectral ratio method to northwest Bohemia, Czech Republic, a region characterized by the persistent occurrence of earthquake swarms in a confined source region at mid-crustal depth. Our method indicates a strong anomaly of high attenuation in the source region of the swarm with an averaged attenuation factor of Qp < 100. The application to S phases fails due to scattered P-phase energy interfering with S phases. The Qp anomaly supports the common hypothesis of highly fractured and fluid saturated rocks in the source region of the swarms in northwest Bohemia. However, high temperatures in a small volume around the swarms cannot be excluded to explain our observations.

On a molecular level, the energy contained in the electromagnetic radiation is transferred through photochemical processes into chemical or thermal energy. In the course of such processes, photo-excitations promote molecules into thermally inaccessible excited states. This induces adaptations of their molecular geometry according to the properties of the excited state. Decay processes towards energetically lower lying states in transient molecular geometries result in the formation of excited state relaxation pathways. The photo-chemical relaxation mechanisms depend on the studied system itself, the interactions with its chemical environment and the character of the involved states. This thesis focuses on systems in which photo-induced deprotonation processes occur at specific atomic sites. To detect these excited-state proton dynamics at the affected atoms, a local probe of molecular electronic structure is required. Therefore, site-selective and orbital-specific K-edge soft X-ray spectroscopy techniques are used here to detect photo-induced proton dynamics in gaseous and liquid sample environments. The protonation of nitrogen (N) sites in organic molecules and the oxygen (O) atom in the water molecule are probed locally through transitions between 1s orbitals and the p-derived molecular valence electronic structure. The used techniques are X-ray absorption spectroscopy (XAS) and resonant inelastic X-ray scattering (RIXS). Both yield access to the unoccupied local valence electronic structure, whereas the latter additionally probes occupied states. We apply these probes in optical pump X-ray probe experiments to investigate valence excited-state proton transfer capabilities of aqueous 2-thiopyridone. A characteristic shift of N K-edge X-ray absorption resonances as well as a distinct X-ray emission line are established by us as spectral fingerprints of N deprotonation in the system. We utilize them to identify photo-induced N deprotonation of 2-thiopyridone on femtosecond timescales, in optical pump N K-edge RIXS probe measurements. We further establish excited state proton transfer mechanisms on picosecond and nanosecond timescales along the dominant relaxation pathways of 2-thiopyridone using transient N K-edge XAS. Despite being an excellent probe mechanism for valence excited-state proton dynamics, the K-edge core-excitation itself also disturbs the electronic structure at specific sites of a molecule. The rapid reaction of protons to 1s photo-excitations can yield directional structural distortions within the femtosecond core-excited state lifetime. These directional proton dynamics can change the energetic separation of eigenstates of the system and alter probabilities for radiative decay between them. Both effects yield spectral signatures of the dynamics in RIXS spectra. Using these signatures of RIXS transitions into electronically excited states, we investigate proton dynamics induced by N K-edge excitation in the amino-acid histidine. The minor core-excited state dynamics of histidine in basic and neutral chemical environments allow us to establish XAS and RIXS spectral signatures of different N protonation states at its imidazole N sites. Based on these signatures, we identify an excitation-site-independent N-H dissociation for N K-edge excitation under acidic conditions. Such directional structural deformations, induced by core-excitations, also make proton dynamics in electronic ground states accessible through RIXS transitions into vibrationally excited states. In that context, we interpret high resolution RIXS spectra of the water molecule for three O K-edge resonances based on quantum-chemical wave packet propagation simulations. We show that highly oriented ground state vibrational modes of coupled nuclear motion can be populated through RIXS processes by preparation of core-excited state nuclear wave packets with the same directionality. Based on that, we analytically derive the possibility to extract one-dimensional directional cuts through potential energy surfaces of molecular systems from the corresponding RIXS spectra. We further verify this concept through the extraction of the gas-phase water ground state potential along three coordinates from experimental data in comparison to quantum-chemical simulations of the potential energy surface. This thesis also contains contributions to instrumentation development for investigations of photo-induced molecular dynamics at high brilliance X-ray light sources. We characterize the setup used for the transient valence-excited state XAS measurements of 2-thiopyridone. Therein, a sub-micrometer thin liquid sample environment is established employing in-vacuum flat-jet technology, which enables a transmission experimental geometry. In combination with a MHz-laser system, we achieve a high detection sensitivity for photo-induced X-ray absorption changes. Additionally, we present conceptual improvements for temporal X-ray optical cross-correlation techniques based on transient changes of multilayer optical properties, which are crucial for the realization of femtosecond time-resolved studies at synchrotrons and free-electron lasers. N2 - Die stetige Bestrahlung der Erde mit intensivem Sonnenlicht stellt einen permanente Energiequelle dar, die zahllose natürliche Prozesse antreibt. Auf molekularer Ebene wird die Energie der elektromagnetischen Strahlung durch photochemische Prozesse in chemische und thermische Energie umgewandelt. Während dieser Prozesse werden thermisch nicht erreichbare angeregte Zustände von Molekülen durch Photoanregungen bevölkert. Dies führt zu Änderungen der Molekülgeometrie, die abhängig von den Eigenschaften der angeregten Zustände sind. Zerfallsprozesse in energetisch tieferliegende Zustände in transienten Molekülgeometrien führen zur Ausbildung von Relaxationspfaden angeregter Zustände. Die Relaxationsmechanismen sind dabei abhängig vom untersuchten System selbst, den Wechselwirkungen mit seiner chemischen Umgebung und den Eigenschaften der beteiligten angeregten Zustände. In dieser Arbeit werden Systeme untersucht, in denen die Protonierung bestimmter Atome im Molekül durch eine Photoanregung geändert werden kann. Um Protonendynamik an den betreffenden Atomen zu untersuchen, wird ein lokaler Zugang zur elektronischen Struktur des Moleküls benötigt. Daher wird in dieser Arbeit K-Kanten Weichröntgenspektroskopie genutzt, um photo-induzierte Protonendynamik in gasförmigen und flüssigen Proben zu untersuchen. Zusätzlich zur Selektivität bzgl. des Elements und des chemischen Zustands des betreffenden Atoms bietet diese Zugang zum Charakter und zur Lokalisierung der bindungsformenden Valenzorbitale. Die Protonierung von Stickstoffatomen (N) in organischen Systemen und die des Sauerstoffatoms (O) im Wassermolekül wird dabei durch Übergänge zwischen stark lokalisierten 1s- und Valenzorbitalen mit 2p-Charakter detektiert. Die verwendeten Spektroskopiemethoden Röntgenabsorption (engl. X-ray absorption spectroscopy, XAS) und resonate inelastische Röntgenstreuung (engl. resonant inelastic X-ray scattering, RIXS) bieten dabei einen lokalen Zugang zur unbesetzten bzw. im Fall von RIXS auch zur besetzten elektronischen Struktur der untersuchten Moleküle. Mit Hilfe der genannten Methoden haben wir in zeitaufgelösten Anrege-Abfrage (engl. pump-probe) Experimenten durch Valenzanregungen induzierte Protonentransfer-Prozesse (engl. excited state proton transfer, ESPT) des Moleküls 2-Thiopyridon in wässriger Lösung untersucht. Eine Verschiebung der N K-Kanten Röntgenabsorptionsresonanzen, sowie eine charakteristische Röntgenemissionslinie werden von uns als spektrale Signaturen einer N Deprotonierung des Systems etabliert. Eine potenzielle photo-induzierte N Deprotonierung des Moleküls wird anhand dieser Signaturen auf femtosekunden Zeitskalen über zeitaufgelöste N K-Kanten RIXS Messungen identifiziert. Protonentransfer-Mechanismen auf Pico- und Nanosekunden Zeitskalen entlang der dominanten Relaxationspfade des Systems werden mit zeitaufgelöstem N K-Kanten XAS untersucht. K-Kanten Rumpfanregungen eignen sich nicht nur ideal zur Detektion von Protonendynamik in valenzangeregten Zuständen, da die Rumpfanregungen selbst auch eine lokalisierte Störung der elektronischen Struktur darstellen. Vor allem die Reaktion von Protonen auf diese Störung innerhalb der 1s Rumpfloch-Lebensdauer von wenigen Femtosekunden kann zu einer gerichteten Verzerrung der Molekülstruktur führen. Die damit verbundenen Änderungen von Übergangsenergien und -wahrscheinlichkeiten sind als Signaturen dieser gerichteten Protonendynamik in RIXS Spektren zugänglich. Anhand von RIXS Übergängen in elektronisch angeregte Zustände untersuchen wir Protonendynamik, die durch N K-Kanten Anregungen an den N Atomen im Imidazolring der Aminosäure Histidin induziert wird. Die schwache Dynamik in basischen und neutralen wässrigen Lösungen erlauben es uns, die Protonierung dieser N Atome mit charakteristischen spektralen Signaturen zu korrelieren. Mit Hilfe dieser Signaturen identifizieren wir eine durch K-Kanten Anregung verursachte N-H Dissoziation in saurer Lösung. Dieser Prozess ist unabhängig davon, an welchem der N Atome des Imidazolrings die Rumpfanregung lokalisiert ist. Solche, durch Rumpfanregungen verursachten, gerichteten Verzerrungen der Molekülstruktur ermöglichen einen Zugang zu Protonendynamik im elektronischen Grundzustand über RIXS Prozesse in dessen vibrationsangeregte Zustände. In diesem Zusammenhang vergleichen wir hochaufgelöste O K-Kanten RIXS Spektren des Wassermoleküls in der Gasphase mit quantenchemischen Simulationen zur Wellenpaketpropagation in den rumpfangeregten Zuständen. Dabei wird deutlich, dass die gerichtete Verzerrung der Molekülstruktur im rumpfangeregten Zustand eine Bevölkerung von Vibrationsmoden des Grundzustandes mit der gleichen Ausrichtung durch den RIXS Prozess verursacht. Anhand dieser Ergebnisse leiten wir ab, unter welchen Bedingungen eine Extraktion eindimensionaler Querschnitte der Potentialfläche des Grundzustandes aus den entsprechenden RIXS Spektren möglich ist. Wir verifizieren diese Methode anhand der Extraktion der Grundzustandspotentialfläche des Wassermoleküls entlang drei unterschiedlicher Richtungen im Vergleich zu den quantenchemischen Rechnungen. Diese Arbeit enthält zudem Beiträge zur Entwicklung von Instrumentierung für Untersuchungen valenzangeregter Moleküldynamik an Röntgenquellen mit hoher Brillianz. Der experimentelle Aufbau, der für die zeitaufgelösten XAS Messungen an 2-Thiopyridon verwendet wurde, wird vorgestellt. Ein sub-Mikrometer dünner Flüssigkeitsflachstrahl erlaubt dabei Messungen in einer Transmissionsgeometrie. In Kombination mit einem MHz-Lasersystem können transiente Absorptionsänderungen effizient detektiert werden. Zudem präsentieren wir Konzepte zur zeitlichen Korrelation von Röntgen- und optischen Lichtpulsen, basierend auf Änderungen der optischen Eigenschaften von Dünnschichtsystemen, die essenziell für Studien transienter Prozesse an Synchrotrons und Freie-Elektronen Lasern mit Femtosekunden Zeitauflösung sind.

Together with nuclear envelope transmembrane proteins, they form the nuclear lamina and are crucial for gene regulation and mechanical robustness of the nucleus and the whole cell. Recently, we characterized Dictyostelium NE81 as an evolutionarily conserved lamin-like protein, both on the sequence and functional level. Here, we show on the structural level that the Dictyostelium NE81 is also capable of assembling into filaments, just as metazoan lamin filament assemblies. Using field-emission scanning electron microscopy, we show that NE81 expressed in Xenopous oocytes forms filamentous structures with an overall appearance highly reminiscent of Xenopus lamin B2. The in vitro assembly properties of recombinant His-tagged NE81 purified from Dictyostelium extracts are very similar to those of metazoan lamins. Super-resolution stimulated emission depletion (STED) and expansion microscopy (ExM), as well as transmission electron microscopy of negatively stained purified NE81, demonstrated its capability of forming filamentous structures under low-ionic-strength conditions. These results recommend Dictyostelium as a non-mammalian model organism with a well-characterized nuclear envelope involving all relevant protein components known in animal cells.

The objective of the present review is to show the impact of different stages of cultivation and processing with regard to the changes induced in the protein fractions. Special focus has been laid on the major seed storage proteins throughout the different stages of processing. The study starts with classical introduction of the extraction and the characterization methods used, while addressing classification approaches of cocoa proteins evolved during the timeline. The changes in protein composition during ripening and maturation of cocoa seeds, together with the possible modifications during the post-harvest processing (fermentation, drying, and roasting), have been documented. Finally, the bioactive potential arising directly or indirectly from cocoa proteins has been elucidated. The “state of the art” suggests that exploration of other potentially bioactive components in cocoa needs to be undertaken, while considering the complexity of reaction products occurring during the roasting phase of the post-harvest processing. Finally, the utilization of partially processed cocoa beans (e.g., fermented, conciliatory thermal treatment) can be recommended, providing a large reservoir of bioactive potentials arising from the protein components that could be instrumented in functionalizing foods.

T1 - Measures and Approaches in Trait-Based Phytoplankton Community Ecology BT - From Freshwater to Marine Ecosystems JF - Frontiers in Marine Science N2 - Trait-based approaches to investigate (short- and long-term) phytoplankton dynamics and community assembly have become increasingly popular in freshwater and marine science. Although the nature of the pelagic habitat and the main phytoplankton taxa and ecology are relatively similar in both marine and freshwater systems, the lines of research have evolved, at least in part, separately. We compare and contrast the approaches adopted in marine and freshwater ecosystems with respect to phytoplankton functional traits. We note differences in study goals relating to functional trait use that assess community assembly and those that relate to ecosystem processes and biogeochemical cycling that affect the type of characteristics assigned as traits to phytoplankton taxa. Specific phytoplankton traits relevant for ecological function are examined in relation to herbivory, amplitude of environmental change and spatial and temporal scales of study. Major differences are identified, including the shorter time scale for regular environmental change in freshwater ecosystems compared to that in the open oceans as well as the type of sampling done by researchers based on site-accessibility. Overall, we encourage researchers to better motivate why they apply trait-based analyses to their studies and to make use of process-driven approaches, which are more common in marine studies. We further propose fully comparative trait studies conducted along the habitat gradient spanning freshwater to brackish to marine systems, or along geographic gradients. Such studies will benefit from the combined strength of both fields.

To increase the efficiency of communication routines, science has to transform its outreach concepts to become more aware of individual needs and demands. The “encoding/decoding” concept as well as critical intercultural communication studies can offer pivotal approaches for this transformation.

T1 - Politics, Social Movements and Extremism T3 - Populism and the crisis of democracy N2 - The contributions to this volume Politics, Social Movements and Extremism take serious the fact that populism is a symptom of the crisis of representation that is affecting parliamentary democracy. Right-wing populism skyrocketed to electoral success and is now part of the government in several European countries, but it also shaped the Brexit campaign and the US presidential election. In Southern Europe, left-wing populism transformed the classical two parties systems into ungovernable three fractions parliaments, whereas in Latin America it still presents an instable alternative to liberal democracy. The varying consequences of populist mobilisation so far consist in the maceration of the established borders of political culture, the distortion of legislation concerning migrants and migration, and the emergence of hybrid regimes bordering on and sometimes leaning towards dictatorship. Yet, in order to understand populism, innovative research approaches are required that need to be capable of overcoming stereotypes and conceptual dichotomies which are deeply rooted in the political debate. The chapters of this volume offer such new theoretical strategies for inquiring into the multi-faceted populist phenomenon. The chapters analyse its language, concepts and its relationship to social media in an innovative way, draw the con -tours of left- and right-wing populism and reconstruct its shifting delimitation to political extremism. Furthermore, they value the most significant aftermath of populist mobilisation on the institutional frame of parliamentary democracy from the limitation of the freedom of press, to the dismantling of the separation of powers, to the erosion of citizenship rights. This volume will be an invaluable reference for students and scholars in the field of political theory, political sociology and European Studies.

A1 - Werner, Karsten T1 - Mental Number Representations in 2D Space JF - Frontiers in Psychology N2 - There is evidence both for mental number representations along a horizontal mental number line with larger numbers to the right of smaller numbers (for Western cultures) and a physically grounded, vertical representation where “more is up.” Few studies have compared effects in the horizontal and vertical dimension and none so far have combined both dimensions within a single paradigm where numerical magnitude was task-irrelevant and none of the dimensions was primed by a response dimension. We now investigated number representations over both dimensions, building on findings that mental representations of numbers and space co-activate each other. In a Go/No-go experiment, participants were auditorily primed with a relatively small or large number and then visually presented with quasi-randomly distributed distractor symbols and one Arabic target number (in Go trials only). Participants pressed a central button whenever they detected the target number and elsewise refrained from responding. Responses were not more efficient when small numbers were presented to the left and large numbers to the right. However, results indicated that large numbers were associated with upper space more strongly than small numbers. This suggests that in two-dimensional space when no response dimension is given, numbers are conceptually associated with vertical, but not horizontal space.

We focused on EF and language-related skills, in particular lexicon size and phonological awareness (PA), because these factors were found to predict spelling in studies predominantly conducted with monolinguals, and because multilingualism can modulate these factors. There is evidence for (a) a bilingual advantage in EF due to constant high cognitive demands through language control, (b) a smaller mental lexicon in German and (c) possibly better PA. Multilinguals in Germany show on average poorer German language proficiency, what can influence performance on language-based tasks negatively. Thus, we included two spelling tasks to tease apart spelling based on lexical knowledge (i.e., word spelling) from spelling based on non-lexical strategies (i.e., non-word spelling). Our sample consisted of heterogeneous third graders from Germany: 69 monolinguals (age: M = 108 months) and 57 multilinguals (age: M = 111 months). On less language-dependent tasks (e.g., non-word spelling, PA, intelligence, short-term memory (STM) and three EF tasks testing switching, inhibition, and working memory) performance of both groups did not differ significantly. However, multilinguals performed significantly more poorly on tasks measuring German lexicon size and word spelling than monolinguals. Regression analyses revealed that for multilinguals, inhibition was related to spelling, whereas switching was the only EF component to influence word spelling in monolinguals and non-word spelling performance in both groups. By adding lexicon size and other language-related factors to the regression models, the influence of switching was reduced to insignificant effects, but inhibition remained significant for multilinguals. Language-related skills best predicted spelling and both language groups shared those variables: PA for word spelling, and STM for non-word spelling. Additionally, multilinguals’ word spelling performance was also predicted by their German lexicon size, and non-word spelling performance by PA. This study offers an in-depth look at spelling acquisition at a certain point of literacy development. Mono- and multilinguals have the predominant factors for spelling in common, but probably due to superior language knowledge, monolinguals were already able to make use of EF during spelling. For multilinguals, German lexicon size was more important for spelling than EF. For multilinguals’ spelling these functions might come into play only at a later stage.

Isokinetic training is well suited for sports in which propulsion is generated through water resistance due to similarities in the resistive mode. Thus, the purpose of this study was to determine the effects of isokinetic training in addition to regular sport-specific training on trunk muscular fitness and body composition in world-class canoeists and to evaluate associations between trunk muscular fitness and canoe-specific performance. Nine world-class canoeists (age: 25.6 ± 3.3 years; three females; four world champions; three Olympic gold medalists) participated in an 8-week progressive isokinetic training with a 6-week block “muscle hypertrophy” and a 2-week block “muscle power.” Pre- and post-tests included the assessment of peak isokinetic torque at different velocities in concentric (30 and 140∘s-1) and eccentric (30 and 90∘s-1) mode, trunk muscle endurance, and body composition (e.g., body fat, segmental lean mass). Additionally, peak paddle force was assessed in the flume at a water current of 3.4 m/s. Significant pre-to-post increases were found for peak torque of the trunk rotators at 30∘s-1 (p = 0.047; d = 0.4) and 140∘s-1 (p = 0.014; d = 0.7) in concentric mode. No significant pre-to-post changes were detected for eccentric trunk rotator torque, trunk muscle endurance, and body composition (p > 0.148). Significant medium-to-large correlations were observed between concentric trunk rotator torque but not trunk muscle endurance and peak paddle force, irrespective of the isokinetic movement velocity (all r ≥ 0.886; p ≤ 0.008). Isokinetic trunk rotator training is effective in improving concentric trunk rotator strength in world-class canoe sprinters. It is recommended to progressively increase angular velocity from 30∘s-1 to 140∘s-1 over the course of the training period.

T1 - Patient safety, cost-effectiveness, and quality of life BT - reduction of delirium risk and postoperative cognitive dysfunction after elective procedures in older adults—study protocol for a stepped-wedge cluster randomized trial (PAWEL Study) JF - Trials N2 - Background Postoperative delirium is a common disorder in older adults that is associated with higher morbidity and mortality, prolonged cognitive impairment, development of dementia, higher institutionalization rates, and rising healthcare costs. The probability of delirium after surgery increases with patients’ age, with pre-existing cognitive impairment, and with comorbidities, and its diagnosis and treatment is dependent on the knowledge of diagnostic criteria, risk factors, and treatment options of the medical staff. In this study, we will investigate whether a cross-sectoral and multimodal intervention for preventing delirium can reduce the prevalence of delirium and postoperative cognitive decline (POCD) in patients older than 70 years undergoing elective surgery. Additionally, we will analyze whether the intervention is cost-effective. Methods The study will be conducted at five medical centers (with two or three surgical departments each) in the southwest of Germany. The study employs a stepped-wedge design with cluster randomization of the medical centers. Measurements are performed at six consecutive points: preadmission, preoperative, and postoperative with daily delirium screening up to day 7 and POCD evaluations at 2, 6, and 12 months after surgery. Recruitment goals are to enroll 1500 patients older than 70 years undergoing elective operative procedures (cardiac, thoracic, vascular, proximal big joints and spine, genitourinary, gastrointestinal, and general elective surgery procedures. Discussion Results of the trial should form the basis of future standards for preventing delirium and POCD in surgical wards. Key aims are the improvement of patient safety and quality of life, as well as the reduction of the long-term risk of conversion to dementia. Furthermore, from an economic perspective, we expect benefits and decreased costs for hospitals, patients, and healthcare insurances. Trial registration German Clinical Trials Register, DRKS00013311.

To understand the species‐assembly mechanisms and dynamics of such ecosystems, it is important to test how local plant‐community diversity and composition is affected by spatial isolation and hence by dispersal limitation and local environmental conditions acting as filters for local species sorting. We used a system of 46 small wetlands (kettle holes)—natural small‐scale freshwater habitats rarely considered in nature conservation policies—embedded in an intensively managed agricultural matrix in northern Germany. We compared two types of kettle holes with distinct topographies (flatsloped, ephemeral, frequently plowed kettle holes vs. steep‐sloped, more permanent ones) and determined 254 vascular plant species within these ecosystems, as well as plant functional traits and nearest neighbor distances to other kettle holes. Differences in alpha and beta diversity between steep permanent compared with ephemeral flat kettle holes were mainly explained by species sorting and niche processes and mass effect processes in ephemeral flat kettle holes. The plant‐community composition as well as the community trait distribution in terms of life span, breeding system, dispersal ability, and longevity of seed banks significantly differed between the two habitat types. Flat ephemeral kettle holes held a higher percentage of non‐perennial plants with a more persistent seed bank, less obligate outbreeders and more species with seed dispersal abilities via animal vectors compared with steep‐sloped, more permanent kettle holes that had a higher percentage of wind‐dispersed species. In the flat kettle holes, plant‐species richness was negatively correlated with the degree of isolation, whereas no such pattern was found for the permanent kettle holes. Synthesis: Environment acts as filter shaping plant diversity (alpha and beta) and plant‐community trait distribution between steep permanent compared with ephemeral flat kettle holes supporting species sorting and niche mechanisms as expected, but we identified a mass effect in ephemeral kettle holes only. Flat ephemeral kettle holes can be regarded as meta‐ecosystems that strongly depend on seed dispersal and recruitment from a seed bank, whereas neighboring permanent kettle holes have a more stable local species diversity.

CY - Hoboken ER - TY - JOUR A1 - Schneider, Birgit A1 - Walsh, Lynda T1 - The politics of zoom BT - Problems with downscaling climate visualizations JF - Geo: Geography and Environment N2 - Following the mandate in the Paris Agreement for signatories to provide “climate services” to their constituents, “downscaled” climate visualizations are proliferating. But the process of downscaling climate visualizations does not neutralize the political problems with their synoptic global sources—namely, their failure to empower communities to take action and their replication of neoliberal paradigms of globalization. In this study we examine these problems as they apply to interactive climate‐visualization platforms, which allow their users to localize global climate information to support local political action. By scrutinizing the political implications of the “zoom” tool from the perspective of media studies and rhetoric, we add to perspectives of cultural cartography on the issue of scaling from our fields. Namely, we break down the cinematic trope of “zooming” to reveal how it imports the political problems of synopticism to the level of individual communities. As a potential antidote to the politics of zoom, we recommend a downscaling strategy of connectivity, which associates rather than reduces situated views of climate to global ones.

This act of listening was considered to be an invisible and amorphous phenomenon, a naturally given mode of perception. This narrative influenced the conditions of listening from the selection of repertoire to the construction of concert halls and programmes. However, as listening moved from the concert hall to the opera house, street music, and jazz venues, new and visceral listening traditions evolved. In turn, the art of listening was shaped by phenomena of the modern era including media innovation and commercialization. This Handbook asks whether, how, and why practices of music listening changed as the audience moved from pleasure gardens and concert venues in the eighteenth century to living rooms in the twentieth century, and mobile devices in the twenty-first. Through these questions, chapters enable a differently conceived history of listening and offer an agenda for future research.

In general, each dimer is characterized by three subdomains: a 20 kDa N-terminal 2x[2Fe2S] cluster containing domain, a 40 kDa central FAD-containing domain and an 85 kDa C-terminal molybdenum cofactor (Moco) containing domain. Aldehyde oxidases have a broad substrate specificity including the oxidation of different aldehydes and N-heterocyclic compounds. AOX enzymes are present in mainly all eukaryotes. Four different homologs of AOX were identified to be present with varying numbers among species and rodents like mice and rats contain the highest number of AOX isoenzymes. There are four identified homologs in mouse named mAOX1, mAOX3, mAOX2, and mAOX4. The AOX homologs in mice are expressed in a tissue-specific manner. Expression of mAOX1 and mAOX3 are almost superimposable and predominantly synthesized in liver, lung, and testis. The richest source of mAOX4 is the Harderian gland, which is found within the eye's orbit in tetrapods. Expression of mAOX2 is strictly restricted to the Bowman’s gland, the main secretory organ of the nasal mucosa. In this study, the four catalytically active mAOX enzymes were expressed in a heterologous expression system in Escherichia coli and purified in a catalytically active form. Thirty different structurally related aromatic, aliphatic and N-heterocyclic compounds were used as substrates, and the kinetic parameters of all four mAOX enzymes were directly compared. The results showed that all enzymes can catalyze a broad range of substrates. Generally, no major differences between mAOX1, mAOX3 and mAOX2 were identified and the substrate specificity of mAOX1, mAOX3, and mAOX2 was broader compared to that of mAOX4 since mAOX4 showed no activity with substrates like methoxy-benzaldehydes, phenanthridine, N1-methyl-nicotinamide, and cinnamaldehyde and 4-(dimethylamino)cinnamaldehyde. We investigated differences at the flavin site of the mAOX enzymes by measuring the ability of the four mAOX enzymes to oxidize NADH in the absence of oxygen. NADH was able to reduce only mAOX3. The four mouse AOXs are also characterized by quantitative differences in their ability to produce superoxide radicals. mAOX2 is the enzyme generating the largest rate of superoxide radicals of around 40% in relation to moles of substrate converted and it is followed by mAOX1 with a ratio of 30%. To understand the factors that contribute to the substrate specificity of mAOX4, site-directed mutagenesis was applied to substitute amino acids in the substrate-binding funnel by the ones present in mAOX1, mAOX3, and mAOX2. The amino acids Val1016, Ile1018 and Met1088 were selected as targets. An increase in activity was obtained by the amino acid exchange M1088V in the active site identified to be specific for mAOX4, to the amino acid identified in mAOX3.

The species is native to the lowlands of Central and Eastern Europe, where population numbers have been in decline in recent past decades. Here, we present the first complete mitochondrial genome of the endangered European fire-bellied toad from Northern Germany recovered using iterative mapping. Phylogenetic analyses including other representatives of the Bombinatoridae placed our German specimen as sister to a Polish B. bombina sequence with high support. This finding is congruent with the postulated Pleistocene history of the species.

ED - Weiland, Sabine T1 - The anthropocene debate and political science T3 - Routledge research in global environmental governance N2 - Anthropocene has become an environmental buzzword. It denotes a new geological epoch that is human?dominated. As mounting scientific evidence reveals, humankind has fundamentally altered atmospheric, geological, hydrological, biospheric, and other Earth system processes to an extent that the risk of an irreversible system change emerges. Human societies must therefore change direction and navigate away from critical tipping points in the various ecosystems of our planet. This hypothesis has kicked off a debate not only on the geoscientific definition of the Anthropocene era, but increasingly also in the social sciences. However, the specific contribution of the social sciences disciplines and in particular that of political science still needs to be fully established. This edited volume analyzes, from a political science perspective, the wider social dynamics underlying the ecological and geological changes, as well as their implications for governance and politics in the Anthropocene. The focus is on two questions: (1) What is the contribution of political science to the Anthropocene debate, e.g. in terms of identified problems, answers, and solutions? (2) What are the conceptual and practical implications of the Anthropocene debate for the discipline of political science? Overall, this book contributes to the Anthropocene debate by providing novel theoretical and conceptual accounts of the Anthropocene, engaging with contemporary politics and policy-making in the Anthropocene, and offering a critical reflection on the Anthropocene debate as such. The volume will be of great interest to students and scholars of political science, global environmental politics and governance, and sustainable development.

Während seiner Amtszeit, die erst 1963 endete, diente Strauß unter fünf verschiedenen Ministern. Damit verkörperte er die Kontinuität der Arbeit und galt nicht von ungefähr als der eigentliche 'Herrscher der Rosenburg', dem Bonner Amtssitz des Ministeriums. Durch seinen Führungsstil, der die Forderung nach Qualität mit einem geradezu paternalistischen Verantwortungsgefühl verband, prägte der Gründungsstaatssekretär den Geist des Hauses für lange Zeit. Obwohl er jüdischer Herkunft war und im Nationalsozialismus zum Kreis der rassisch Verfolgten gehört hatte, griff Strauß bei der Auswahl des Personals allerdings in hohem Maße auf die Mitarbeit von Personen zurück, die durch ihre Tätigkeit im 'Dritten Reich' belastet waren. Warum dies so war, sucht der Autor nicht nur anhand biografischer Prägungen, die Strauß im Kaiserreich, in der Weimarer Republik, dem Nationalsozialismus und der Besatzungszeit erfahren hatte, sondern auch durch eine umfassende Darstellung der wesentlichen Merkmale und Kennzeichen seiner Personalpolitik zu ergründen: Wie weit reichte sein Einfluss Welche Rolle spielte er bei Auswahl und Beförderungen, in erster Linie der Beamten des höheren Dienstes, in Abgrenzung zu anderen Akteuren Und in welchem Maße war er bei seinen Entscheidungen durch institutionelle Rahmenbedingungen eingeschränkt 366 pp Y1 - 2019 IS - 1 PB - Vandenhoeck & Ruprecht CY - Göttingen ER -
