TY - JOUR A1 - Wagner, Rolf T1 - Zuständigkeit nach der EuGVVO für abgetretene Forderungen in Versicherungs-, Verbraucher- und Arbeitssachen BT - eine Darstellung unter besonderer Berücksichtigung der Rechtsprechung des EuGH JF - Recht der internationalen Wirtschaft N2 - Im Rahmen der EuGVVO hat der Kläger seine Klage grundsätzlich in dem Staat zu erheben, in dem der Beklagte seinen Wohnsitz hat. Ausnahmen hiervon gibt es insbesondere in Versicherungs-, Verbraucher- und Arbeitssachen. Der Versicherungsnehmer und der Verbraucher können gegen den Versicherer bzw. gegen den Unternehmer insbesondere an ihrem Wohnsitz gerichtlich vorgehen. Der Arbeitnehmer kann seine Klage gegen den Arbeitgeber zwar nicht an seinem Wohnsitz, aber an dem Ort erheben, an dem oder von dem aus er gewöhnlich seine Arbeit verrichtet (gewöhnlicher Arbeitsort). Zuständigkeitsrechtliche Probleme ergeben sich, wenn der Versicherungsnehmer, der Verbraucher oder der Arbeitnehmer seine Forderung an einen Dritten abtritt. Dann ist in erster Linie zu klären, ob der Dritte die abgetretene Forderung auch an seinem Wohnsitz bzw. an seinem gewöhnlichen Arbeitsort erheben kann. Diese Problematik ist Gegenstand des Beitrags.

Der Europäische Beschluss zur vorläufigen Kontenpfändung (EuKPfB) steht dem Gläubiger als eine Alternative zu den Maßnahmen zur vorläufigen Pfändung nach dem nationalen Recht zur Verfügung (Art. 1 Abs. 2 EuKPfVO). Auf den ersten Blick weist der EuKPfB eine gewisse Nähe zu einer Kontenpfändung aufgrund eines dinglichen Arrests auf. Im Folgenden soll daher untersucht werden, ob und ggfs. welche konzeptionellen Unterschiede es diesbezüglich gibt. In diesem Zusammenhang ist auch zu klären, was sich hinter dem EuKPfB eigentlich verbirgt. N2 - The enforcement of a claim, even in cross-border situations, must not be jeopardised by the debtor transferring or debiting funds from his account. A creditor domiciled in State A has various options for having bank accounts of his debtor in State B seized. Thus, he can apply for an interim measure in State A according to national law and may have this measure enforced under the Brussels Ibis Regulation in State B by way of attachment of accounts. Alternatively, he may proceed in accordance with the European Account Preservation Order Regulation (hereinafter: EAPOR). This means that he must obtain a European account preservation order in State A which must be enforced in State B. By comparing these two options the author deals with the legal nature of the European account preservation order and with the subtleties of enforcement under the EAPOR.

Specifically, we argue for a critical approach to GCE that emphasizes the significance of language as symbolic power by drawing on the concepts of critical literacy (e.g., Freire 1983; Janks 2014) and symbolic competence (Kramsch 2006; 2011; 2021). To illustrate the necessity of such a critical approach to GCE, we critically analyze teaching materials designed for the English language classroom as provided by the curriculum framework (KMK/ BMZ 2016). The analysis reveals how reliance on dominant Western liberal and neoliberal epistemologies, norms, and discourses might inadvertently reinforce the very inequalities that GCE actually seeks to address. By foregrounding the relationship between language, symbolic power, and GCE, we further redesign these teaching materials and incorporate pedagogical and methodological principles which are in line with a critical literacy and symbolic competence.

The UCST-exhibiting block in the copolymer consists of the zwitterionic poly(4((3-methacrylamidopropyl)dimethylammonio)butane-1-sulfonate), abbreviated as PSBP. The LCST-exhibiting block consists of the nonionic poly(N-isopropylacrylamide), abbreviated as PNIPAM. The as-prepared PSBP80-b-PNIPAM(400) films feature a three-layer structure, i.e., PNIPAM, mixed PNIPAM and PSBP, and PSBP. Both blocks have similar transition temperatures (TTs), namely around 32 degrees C for PNIPAM, and around 35 degrees C for PSBP, and with a two-step heating protocol (20 degrees C to 40 degrees C and 40 degrees C to 80 degrees C), both TTs are passed. The response to such a thermal stimulus turns out to be complex. Besides a three-step process (shrinkage, rearrangement, and reswelling), a continuous transfer of D2O from the PNIPAM to the PSBP block is observed. Due to the existence of both, LCST and UCST blocks in the PSBP80-b-PNIPAM(400 )film, the water transfer from the contracting PNIPAM, and mixed layers to the expanding PSBP layer occurs. Thus, the hydration kinetics and thermal response differ markedly from a thermoresponsive polymer film with a single LCST transition.

BT - it depends on leader (un-) predictability JF - Journal of leadership & organizational studies N2 - Although prior research has shown that reward provision might sometimes increase creativity, little is known about how leadership that clarifies effort-reward contingencies (i.e., contingent reward leadership) is related to team creativity. Drawing on the theory of learned industriousness, we argue that contingent reward leadership can enhance team knowledge exchange and, in turn, team creative performance. However, we propose that this relationship is moderated by leader unpredictability, which can create uncertainty about resource allocation, thereby undermining the otherwise positive effect of contingent reward leadership. In a two-source, lagged design (three-wave) field study with data from 60 organizational teams, we found a conditional indirect (moderated mediation) effect of contingent reward leadership on team creative performance through team knowledge exchange. This conditional indirect effect was positive when leader unpredictability was low, and negative when leader unpredictability was high. Our research provides leaders with clear and actionable advice by showing that contingent reward leadership promotes team creative performance only when leaders act in predictable and consistent ways.

However, previous research tells us little about which leaders and under which circumstances leaders engage in visionary leadership. We draw on theories of human and social capital to argue that leader work centrality is an important antecedent of visionary leadership, and especially so for leaders with low organizational tenure. Moreover, we propose that visionary leadership then provides followers with meaningfulness and thereby decreases their turnover intentions. Our predictions were confirmed by data from a two-wave, lagged-design field study with 101 leader-follower dyads. Overall, our research identifies an important antecedent of visionary leadership, a specific situation in which this antecedent is particularly important, and provides empirical evidence for why visionary leadership can bind followers to an organization.

To overcome this obstacle, the current study investigates whether posthypnotic suggestions (PHSs) can enhance food-related decisions by measuring food choices and subjective ratings. After assessing hypnotic susceptibility in Session 1, at the beginning of Session 2, a PHS was delivered aiming to increase the desirability of healthy food items (e.g., vegetables and fruit). After the termination of hypnosis, a set of two tasks was administrated twice, once when the PHS was activated and once deactivated in counterbalanced order. The task set consisted of rating 170 pictures of food items, followed by an online supermarket where participants were instructed to select enough food from the same item pool for a fictitious week of quarantine. After 1 week, Session 3 mimicked Session 2 without renewed hypnosis induction to assess the persistence of the PHS effects. The Bayesian hierarchical modeling results indicate that the PHS increased preferences and choices of healthy food items without altering the influence of preferences in choices. In contrast, for unhealthy food items, not only both preferences and choices were decreased due to the PHS, but also their relationship was modified. That is, although choices became negatively biased against unhealthy items, preferences played a more dominant role in unhealthy choices when the PHS was activated. Importantly, all effects persisted over 1 week, qualitatively and quantitatively. Our results indicate that although the PHS affected healthy choices through resolve, i.e., preferred more and chosen more, unhealthy items were probably chosen less impulsively through effortful suppression. Together, besides the translational importance of the current results for helping the obesity epidemic in modern societies, our results contribute theoretically to the understanding of hypnosis and food choices.

The renouncement of dispensable consumption will, however, only establish itself as a significant lifestyle if consumers do not perceive reduced consumption as a personal sacrifice. Since prior research has not yielded a consistent understanding of the relationship between anti-consumption and personal well-being, this paper aims to examine three factors about which theory implies that they may moderate this relationship: decision-control empowerment, market-control empowerment and the value of materialism. Design/methodology/approach The analysis is based on data from a large-scale, representative online survey (N = 1,398). Structural equation modelling with latent interaction effects is used to test how three moderators (decision-control empowerment, market-control empowerment and materialism) affect the relationship amongst four types of anti-consumption (e.g. voluntary simplicity) and three different well-being states (e.g. subjective well-being). Findings While both dimensions of empowerment almost always directly promote consumer well-being, significant moderation effects are present in only a few but meaningful cases. Although the materialism value tends to reduce consumers’ well-being, it improves the well-being effect of two anti-consumption styles. Research limitations/implications Using only one sample from a wealthy country is a limitation of the study. Researchers should replicate the findings in different nations and cultures. Practical implications Consumer affairs practitioners and commercial marketing for sustainably produced, high-quality and long-lasting goods can benefit greatly from these findings. Social implications This paper shows that sustainable marketing campaigns can more easily motivate consumers to voluntarily reduce their consumption for the benefit of society and the environment if a high level of market-control empowerment can be communicated to them. Originality/value This study provides differentiated new insights into the roles of consumer empowerment, i.e. both decision-control empowerment and market-control empowerment, and the value of materialism to frame specific relationships between different anti-consumption types and various well-being states.

As such beliefs reflect how individuals behave, think, and act, they are key for successful entrepreneurial activities. While existing literature mainly analyzes the influence of the task-related construct of entrepreneurial self-efficacy, we take a different perspective and investigate, based on a representative sample of 1,405 German business founders, how the personality characteristic of generalized self-efficacy influences start-up performance as measured by a broad set of business outcomes up to 19 months after business creation. Outcomes include start-up survival and entrepreneurial income, as well as growth-oriented outcomes such as job creation and innovation. We find statistically significant and economically important positive effects of high scores of self-efficacy on start-up survival and entrepreneurial income, which become even stronger when focusing on the growth-oriented outcome of innovation. Furthermore, we observe that generalized self-efficacy is similarly distributed between female and male business founders, with effects being partly stronger for female entrepreneurs. Our findings are important for policy instruments that are meant to support firm growth by facilitating the design of more target-oriented offers for training, coaching, and entrepreneurial incubators.

Based on real-time online-survey data comprising more than 20,000 observations, we analyze the impact of this program on the confidence to survive the crisis. We investigate how the digitalization level of self-employed individuals influences the program’s effectiveness. Employing propensity score matching, we find that the emergency-aid program had only moderately positive effects on the confidence of self-employed to survive the crisis. However, self-employed whose businesses were highly digitalized, benefitted much more from the state aid than those whose businesses were less digitalized. This only holds true for those self-employed, who started the digitalization processes already before the crisis. Taking a regional perspective, we find suggestive evidence that the quality of the regional broadband infrastructure matters in the sense that it increases the effectiveness of the emergency-aid program. Our findings show the interplay between governmental support programs, the digitalization levels of entrepreneurs, and the regional digital infrastructure. The study helps public policy to improve the impact of crisis-related policy instruments, ultimately increasing the resilience of small firms in times of crises.

Growth and final body size exhibit marked plastic responses to ecological conditions. Among the shortest are the pygmoid people of Rampasasa, Flores, Indonesia, who still live under most secluded insular conditions. Genetics and nutrition are usually considered responsible for the poor growth in many parts of this world, but evidence is accumulating on the prominent impact of social embedding on child growth. Secular trends not only in the growth of height, but also in body proportions, accompany the secular changes in the social, economic and political conditions, with major influences on the emotional and educational circumstances under which the children grow up (Bogin, 2021). Aspects of developmental tempo and aspects of sports were discussed, and the impact of migration by the example of women from Bangladesh who grew up in the UK. Child growth was considered in particular from the point of view of strategic adjustments of individual size within the network of its social group. Theoretical considerations on network characteristics were presented and related to the evolutionary conservation of growth regulating hypothalamic neuropeptides that have been shown to link behavior and physical growth in the vertebrate species. New statistical approaches were presented for the evaluation of short term growth measurements that permit monitoring child growth at intervals of a few days and weeks.

Especially when looking for small variations and increments, such as mini growth spurts, high precision instruments or frequent measurements are necessary. Daily measurements however require a lot of effort, both for anthropologists and for the subjects. Therefore, new sophisticated approaches are needed that reduce fluctuations and reveal underlying patterns. Objectives: Changepoints are abrupt variations in the properties of time series data. In the context of growth, such variations could be variation in mean height. By adjusting the variance and using different growth models, we assessed the ability of changepoint analysis to analyse short-term growth and detect mini growth spurts. Sample and Methods: We performed Bayesian changepoint analysis on simulated growth data using the bcp package in R. Simulated growth patterns included stasis, linear growth, catch-up growth, and mini growth spurts. Specificity and a normalised variant of the Matthews correlation coefficient (MCC) were used to assess the algorithm’s performance. Welch’s t-test was used to compare differences of the mean. Results: First results show that changepoint analysis can detect mini growth spurts. However, the ability to detect mini growth spurts is highly dependent on measurement error. Data preparation, such as ranking and rotating time series data, showed negligible improvements. Missing data was an issue and may affect the prediction quality of the classification metrics. Conclusion: Changepoint analysis is a promising tool to analyse short-term growth. However, further optimisation and analysis of real growth data is needed to make broader generalisations.

With the guidance of experienced human biologists, statisticians, and programmers, students have the unique chance to analyze their own data and gain valuable insights. This interdisciplinary setting not only bridges different research areas but also leads to highly valuable outputs. The progress of students within just a few days is truly remarkable, especially when they are motivated and receive immediate feedback on their questions, problems, and results. The Summer School covers a wide range of topics, with this year’s focus mainly on two areas: understanding the impact of socioeconomic and physiological factors on human development and mastering statistical techniques for analyzing data such as changepoint analysis and the St. Nicolas House Analysis (SNHA) to visualize interacting variables. The latter technique, born out of the Summer School’s emphasis on gaining comprehensive data insights and understanding major relationships, has proven to be a valuable tool for researchers in the field. The articles in this special issue demonstrate that the Summer School in Gülpe stands as a testament to the power of practical learning and collaboration. Students who attend not only gain hands-on experience but also benefit from the expertise of professionals and the opportunity to engage with peers from diverse disciplines.

It can come hand in hand with emotional stress which is known to influence the growth of children. Objective: The aim of this study was to analyse whether type of migration (forced or voluntary) and the geographic direction had influenced the growth of Polish children after World War II. Sample and Methods: A sub dataset of 2,208 individuals between the ages of 2-20, created from data of the 2nd Polish Anthropological Survey carried out in 1966–1969, including anthropometrical data and social and demographic information based on questionnaire, was used to analyse migration effects. Results: No association could be found between the direction of migration and the height of the children. The confidence intervals of the means of all classified migration categories overlap significantly and the effect size of the influence of migration category on height is ds=.140, which is too low to see any effects, even if there were one. Conclusion: Neither forced nor voluntary migration in Poland after World War II led to a change in height in children of migrating families.

Growth is defined as increase in size over time. The understanding of growth includes an understanding of the binary concept of physical time and individual tempo. Excess food causes tempo acceleration. Food restriction delays tempo. Tempo reflects the pace of life. It is a dynamic physical response to a broad spectrum of social, economic, political, and emotional (SEPE) factors and can affect life expectancy. Variations in tempo create distortions of the z-score patterns of height and weight. Illness or intermediate food shortage lead to intermediate halts in development and create short dips in the z-score patterns. Children who develop throughout life at delayed pace usually run at lower z-scores for height and weight, and show a characteristic adolescent trough; children who develop throughout life at faster than average pace usually run at higher z-scores and show a characteristic adolescent peak in their z-score patterns. During adolescence, almost half of the height variance is due to tempo variation. There is not one tempo for the whole body. Different organ systems grow and mature at different pace.

JF - Human biology and public health N2 - Stunting is commonly linked with undernutrition. Yet, already after World War I, German pediatricians questioned this link and stated that no association exists between nutrition and height. Recent analyses within different populations of Low- and middle-income countries with high rates of stunted children failed to support the assumption that stunted children have a low BMI and skinfold sickness as signs of severe caloric deficiency. So, stunting is not a synonym of malnutrition. Parental education level has a positive influence on body height in stunted populations, e.g., in India and in Indonesia. Socially disadvantaged children tend to be shorter and lighter than children from affluent families. Humans are social mammals; they regulate growth similar to other social mammals. Also in humans, body height is strongly associated with the position within the social hierarchy, reflecting the personal and group-specific social, economic, political, and emotional environment. These non-nutritional impact factors on growth are summarized by the concept of SEPE (Social-Economic-Political-Emotional) factors. SEPE reflects on prestige, dominance-subordination, social identity, and ego motivation of individuals and social groups.

We concentrate on Muslim norms of dressing and undressing as a potential focal point of cultural and religious diversity. Inspired by Ray’s (2019) idea of racialized organizations, we assume that state-run organizations in Germany are characterized by a strong commitment to religious tolerance and non-discrimination but also marked by anti- Muslim sentiment prevalent among the German population. Our study looks for mechanism that explain how Human Service Organizations accommodate Muslim body practices. It draws on qualitative empirical data collected in state-run hospitals, schools and swimming pools in Germany. Our analyses show that the organizations draw on formal and informal rules at the organizational level to accommodate Islam. We identify five general organizational mechanisms that may hinder Muslim accommodation in human service organizations. In particular, we see a risk of decoupling between the expectation of religious tolerance and processes that lead to informal discrimination, driven mainly by the difficulty of controlling group dynamics among users.

BT - an analytical model and evidence from a highly decentralized country JF - International migration review N2 - A growing number of studies have recently postulated a so-called local turn in the study of immigrant and refugee integration policy. A fundamental, yet untested, assumption of this body of research is that local (sub-national) policies and administrations shape how migrants and refugees integrate into society. We develop and apply an analytical model using multilevel modeling techniques based on large-N, longitudinal survey data (N > 9000) with refugees (2012–2018) in a highly decentralized country (Germany) to estimate the scope for local policy effects net of individual-level and state- and district-level characteristics. We show that region and district-level variation in integration outcomes across multiple dimensions (employment, education, language, housing, social) is limited (∼5%) within 4–8 years after immigration. We find modest variation in policy indicators (∼10%), which do not appear to directly translate into outcomes. We discuss implications for the study of local policies and the potential for greater convergence between administrative and political science, interested in governance structures and policy variation, and sociology and economics, interested primarily in integration outcomes.

Following the grounded theory methodology, we develop the affordances-actualizations-outcomes model, explaining how immediate goals associated with features translate into outcomes. In the quantitative study, we test the model by applying structural equation modeling.

In the solid state, the compound exhibits 1D ([AgI2](-))(n) chains that are stabilized by the N-butyl pyridinium cation. The 1D structure is further manifested by the formation of long, needle-like crystals, as revealed from electron microscopy. As the general composition is derived from metal halide-based ionic liquids, the compound has a low melting point of 100-101 degrees C, as confirmed by differential scanning calorimetry. Most importantly, the compound has a conductivity of 10(-6) S cm(-1) at room temperature. At higher temperatures the conductivity increases and reaches to 10(-4 )S cm(-1) at 70 degrees C. In contrast to AgI, however, the current material has a highly anisotropic 1D arrangement of the ionic domains. This provides direct and tuneable access to fast and anisotropic ionic conduction. The material is thus a significant step forward beyond current ion conductors and a highly promising prototype for the rational design of highly conductive ionic solid-state conductors for battery or solar cell applications.

The dependency is based on the correlation coefficient, which is visualized as an undirected graph. The network prediction is improved by a bootstrap routine. It enables the computation of the empirical p-value, which is used to evaluate the significance of the predicted edges. Synthetic data generated with the Monte Carlo method were used to firstly compare the Python package with the original R package, and secondly to evaluate the predicted network using the sensitivity, specificity, balanced classification rate and the Matthew's correlation coefficient (MCC). The Python implementation yields the same results as the R package. Hence, the algorithm was correctly ported into Python. The SNHA scores high specificity values for all tested graphs. For graphs with high edge densities, the other evaluation metrics decrease due to lower sensitivity, which could be partially improved by using bootstrap,while for graphs with low edge densities the algorithm achieves high evaluation scores.

What is striking is that the Council's sanctions regimes are subject to detailed sets of rules and decision criteria. The scholarship on human rights in counterterrorism assumes that rights advocacy and court litigation have prompted this development. The article complements this literature by highlighting an unexplored internal driver of legal-regulatory decision-making and explores how mixed-motive interest constellations among Security Council members have affected the extent of committee regulations and the content of decisions taken by sanctions committees. Based on internal documents and diplomatic cables, a comparative analysis of the Iraq sanctions regime and the counterterrorism sanctions regime demonstrates that mixed-motive interest constellations among Security Council members provide incentives to elaborate rules to guide decision-making resulting in legal-regulatory sanctions governance, even if the human rights of targeted individuals are not at stake. For comparative leverage and to assess the limits of the proposed mechanism, the analysis is briefly extended to other sanctions regimes targeting individuals (Democratic Republic of the Congo and Sudan). The findings have implications for this essential tool of the Security Council to react to threats to peace as diverse as counterterrorism, nonproliferation, and internal armed conflict. N2 - Les sanctions jouent un rôle essentiel dans la lutte du Conseil de sécurité contre le terrorisme. Ce qui est frappant, c'est que les régimes de sanctions du Conseil sont soumis à un ensemble détaillé de règles et de critères de décision. La recherche sur les droits de l'homme dans le cadre de la lutte contre le terrorisme suppose que la défense des droits et les litiges devant les tribunaux sont à l'origine de cet état de fait. L'article vient compléter cette littérature en soulignant un facteur interne inexploré dans la prise de décisions légales/réglementaires. Il analyse les répercussions des constellations de divers intérêts chez les membres du Conseil de sécurité sur l’étendue des réglementations de comité et le contenu des décisions prises par les comités de sanctions. En s'appuyant sur des documents internes et des câbles diplomatiques, une analyse comparative du régime de sanctions de l'Irak et du régime de sanctions de lutte contre le terrorisme démontre que ces constellations de divers intérêts chez les membres du Conseil de sécurité motivent l’élaboration de règles pour guider la prise de décisions débouchant sur une gouvernance de sanctions légales/réglementaires, même quand les droits de l'homme des personnes ciblées ne sont pas en jeu. À des fins de comparaison, et pour évaluer les limites du mécanisme proposé, l'analyse fait l'objet d'un bref élargissement à d'autres régimes de sanctions ciblant des personnes (RDC et Soudan). Les conclusions s'accompagnent d'implications pour cet outil essentiel du Conseil de sécurité dans la réaction aux menaces pour la paix : lutte contre le terrorisme, non-prolifération et conflit armé interne. N2 - Las sanciones son fundamentales para los esfuerzos del Consejo de Seguridad en la lucha contra el terrorismo. Lo sorprendente es que los regímenes de sanciones del Consejo están sujetos a detallados conjuntos de normas y criterios de decisión. Los académicos especializados en cuestión de derechos humanos en la lucha antiterrorista parten de la base de que la defensa de los derechos y los litigios ante los tribunales han impulsado esta tendencia. Este artículo complementa esta bibliografía poniendo de relieve un impulsor interno inexplorado de la toma de decisiones jurídico-normativas y analiza cómo las constelaciones de intereses de motivación mixta entre los miembros del Consejo de Seguridad han afectado al alcance de las normativas de los comités y al contenido de las decisiones adoptadas por los comités de sanciones. Basándose en documentos internos y telegramas diplomáticos, un análisis comparativo del régimen de sanciones contra Irak con el régimen de sanciones antiterroristas demuestra que las constelaciones de intereses de motivación mixta entre los miembros del Consejo de Seguridad proporcionan incentivos para la elaboración de normas que guíen la toma de decisiones dando lugar a una gobernanza jurídica-normativa de las sanciones, aun cuando no estén en juego los derechos humanos de las personas sancionadas. A efectos comparativos y con el fin de evaluar los límites del mecanismo propuesto, el análisis se amplía someramente a otros regímenes de sanciones dirigidos a individuos (RDC y Sudán). Las conclusiones tienen implicaciones para esta herramienta esencial del Consejo de Seguridad a fin de reaccionar ante amenazas a la paz tan diversas como la lucha antiterrorista, la no proliferación y los conflictos armados internos.

Yet, keeping learners motivated and ensuring high satisfaction is one of the challenges today's course designers face. Therefore, many MOOC providers employed gamification elements that only boost extrinsic motivation briefly and are limited to platform support. In this article, we introduce and evaluate a gameful learning design we used in several iterations on computer science education courses. For each of the courses on the fundamentals of the Java programming language, we developed a self-contained, continuous story that accompanies learners through their learning journey and helps visualize key concepts. Furthermore, we share our approach to creating the surrounding story in our MOOCs and provide a guideline for educators to develop their own stories. Our data and the long-term evaluation spanning over four Java courses between 2017 and 2021 indicates the openness of learners toward storified programming courses in general and highlights those elements that had the highest impact. While only a few learners did not like the story at all, most learners consumed the additional story elements we provided. However, learners' interest in influencing the story through majority voting was negligible and did not show a considerable positive impact, so we continued with a fixed story instead. We did not find evidence that learners just participated in the narrative because they worked on all materials. Instead, for 10-16% of learners, the story was their main course motivation. We also investigated differences in the presentation format and concluded that several longer audio-book style videos were most preferred by learners in comparison to animated videos or different textual formats. Surprisingly, the availability of a coherent story embedding examples and providing a context for the practical programming exercises also led to a slightly higher ranking in the perceived quality of the learning material (by 4%). With our research in the context of storified MOOCs, we advance gameful learning designs, foster learner engagement and satisfaction in online courses, and help educators ease knowledge transfer for their learners.

In this context, we investigate whether the motives of becoming an entrepreneur influence the subsequent entrepreneurial development. In our analysis, we examine a broad range of business outcomes including survival and income, as well as job creation, and expansion and innovation activities for up to 40 months after business formation. Using the self-determination theory as conceptual background, we aggregate the start-up motives into a continuous motivational index. We show – based on a unique dataset of German start-ups from unemployment and non-unemployment – that the later business performance is better, the higher they score on this index. Effects are particularly strong for growth-oriented outcomes like innovation and expansion activities. In a next step, we examine three underlying motivational categories that we term opportunity, career ambition, and necessity. We show that individuals driven by opportunity motives perform better in terms of innovation and business expansion activities, while career ambition is positively associated with survival, income, and the probability of hiring employees. All effects are robust to the inclusion of a large battery of covariates that are proven to be important determinants of entrepreneurial performance.

BT - how differences in perception shape attitudes towards progressive taxation JF - European sociological review N2 - Empirically, the poor are more likely to support increases in the level of tax progressivity than the rich. Such income-stratified tax preferences can result from differences in preferences of what should be taxed as argued by previous literature. However, it may also result from income-stratified perceptions of what is taxed. This paper argues that the rich perceive higher levels of tax progressivity than the poor and that tax perceptions affect individuals’ support for progressive taxation. Using data from an Austrian survey experiment, we test this argument in three steps: First, in line with past research, we show that individuals’ income positions are connected to individuals’ tax preferences as a self-interest rationale would predict. However, second, we show that this variation is mainly driven by income-stratified tax perceptions. Third, randomly informing a subset of the sample about actual tax rates, we find that changing tax perceptions causally affects support for redistributive taxation among those who initially overestimated the level of tax progressivity. Our results indicate that tax perceptions are relevant for forming tax preferences and suggest that individuals are more polarized in their perceptions of who pays how much taxes than in their support for who should pay how much tax.

In this paper, we perform a large-scale particle-in-cell simulation that generates a single shock with parameters motivated from supernova remnants. Within the foreshock, reflected electrons excite the oblique whistler instability and produce electromagnetic whistler waves, which comove with the upstream flow and as nonlinear structures eventually reach radii of up to 5 ion-gyroradii. We show that the inner electromagnetic configuration of the whistlers evolves into complex nonlinear structures bound by a strong magnetic field around four times the upstream value. Although these nonlinear structures do not in general interact with cospatial upstream electrons, they resonate with electrons that have been reflected at the shock. We show that they can scatter, or even trap, reflected electrons, confining around 0.8% of the total upstream electron population to the region close to the shock where they can undergo substantial pre-acceleration. This acceleration process is similar to, yet approximately three times more efficient than, stochastic shock drift acceleration.

However, most studies focused on developing models for the same area or the same precipitation event. It is thus not obvious how transferable the models are in space. This study evaluates the performance of a convolutional neural network (CNN) based on the U-Net architecture and the random forest (RF) algorithm to predict flood water depth, the models' transferability in space and performance improvement using transfer learning techniques. We used three study areas in Berlin to train, validate and test the models. The results showed that (1) the RF models outperformed the CNN models for predictions within the training domain, presumable at the cost of overfitting; (2) the CNN models had significantly higher potential than the RF models to generalize beyond the training domain; and (3) the CNN models could better benefit from transfer learning technique to boost their performance outside training domains than RF models.

A1 - von Staden, Andreas T1 - A room full of ‘views’ BT - introducing a new dataset to explore compliance with the decisions of the UN Human Rights Treaty Bodies’ individual complaints procedures JF - Journal of conflict resolution N2 - Quantitative research into the effectiveness of the UN human rights treaty bodies (UNTBs) in eliciting remedial responses from states is impeded by a lack of usable data on how states respond to their decisions. The new Treaty Body Views Dataset (TBVD) aims to fill this gap. It comprises details on all published decisions in individual complaints cases issued by the UNTBs between 1979 and 2019 and matches these with information on their state of compliance. The TBVD can be used for research on the activities of the treaty bodies, the nature of the decisions themselves, or state behavior following a decision. An empirical application illustrates how the TBVD can advance knowledge about the factors that correlate with compliance with adverse UNTB decisions. Results show that the likelihood of implementation hinges critically on decision-level characteristics, and reveal differences and similarities between compliance with UNTB decisions and regional human rights court judgments.

JF - European journal of political research N2 - Public opinion polls have become vital and increasingly visible parts of election campaigns. Previous research has frequently demonstrated that polls can influence both citizens' voting intentions and political parties' campaign strategies. However, they are also fraught with uncertainty. Margins of error can reflect (parts of) this uncertainty. This paper investigates how citizens' voting intentions change due to whether polling estimates are presented with or without margins of error. Using a vignette experiment (N=3224), we examine this question based on a real-world example in which different election polls were shown to nationally representative respondents ahead of the 2021 federal election in Germany. We manipulated the display of the margins of error, the interpretation of polls and the closeness of the electoral race. The results indicate that margins of error can influence citizens' voting intentions. This effect is dependent on the actual closeness of the race and additional interpretative guidance provided to voters. More concretely, the results consistently show that margins of error increase citizens' inclination to vote for one of the two largest contesting parties if the polling gap between these parties is small, and an interpretation underlines this closeness. The findings of this study are important for three reasons. First, they help to determine whether margins of error can assist citizens in making more informed (strategic) vote decisions. They shed light on whether depicting opinion-poll uncertainty affects the key features of representative democracy, such as democratic accountability. Second, the results stress the responsibility of the media. The way polls are interpreted and contextualized influences the effect of margins of error on voting behaviour. Third, the findings of this paper underscore the significance of including methodological details when communicating scientific research findings to the broader public.

Las obvias limitaciones a su libertad de movimiento y la relativa facilidad con la que grandes cantidades de ellos pudieron ser segregados y sus raciones controladas fueron factores cruciales a la hora de explicar la muerte de más de tres millones de prisioneros de guerra soviéticos, la inmensa mayoría de ellos como consecuencia directa o indirecta del hambre y la desnutrición. El proceso se inició con un claro desinterés por encargarse debidamente de aquella gente, pero con la llegada del otoño derivó en la decisión clara y meditada de matar de hambre a todos los que no pudieran aportar su trabajo a la economía de guerra o a los ejércitos alemanes.
