Spatial and temporal variation in perceived predation risk is an important determinant of movement and foraging activity of animals. Foraging in this landscape of fear, individuals need to decide where and when to move, and what resources to choose. Foraging theory predicts the outcome of these decisions based on energetic trade-offs, but complex interactions between perceived predation risk and preferences of foragers for certain functional traits of their resources are rarely considered. Here, we studied the interactive effects of perceived predation risk on food trait preferences and foraging behavior in bank voles (Myodes glareolus) in experimental landscapes. Individuals (n = 19) were subjected for periods of 24 h to two extreme, risk-uniform landscapes (either risky or safe), containing 25 discrete food patches, filled with seeds of four plant species in even amounts. Seeds varied in functional traits: size, nutrients, and shape. We evaluated whether and how risk modifies forager preference for functional traits. We also investigated whether perceived risk and distance from shelter affected giving-up density (GUD), time in patches, and number of patch visits. In safe landscapes, individuals increased time spent in patches, lowered GUD and visited distant patches more often compared to risky landscapes. Individuals preferred bigger seeds independent of risk, but in the safe treatment they preferred fat-rich over carb-rich seeds. Thus, higher densities of resource levels remained in risky landscapes, while in safe landscapes resource density was lower and less diverse due to selective foraging. Our results suggest that the interaction of perceived risk and dietary preference adds an additional layer to the cascading effects of a landscape of fear which affects biodiversity at resource level.
SOEP-LEE2
(2023)
This article presents the new linked employee-employer study of the Socio-Economic Panel (SOEP-LEE2), which offers new research opportunities for various academic fields. In particular, the study contains two waves of an employer survey for persons in dependent work that is also linkable to the SOEP, a large representative German annual household panel (SOEP-LEE2-Core). Moreover, SOEP-LEE2 includes two waves of self-employed surveys based on self-employed in the SOEP-Core (SOEP-LEE2-Self-employed) and three additional representative employer surveys, independent of the SOEP in terms of sampling employers (SOEP-LEE2-Compare). Survey topics include digitalisation and cybersecurity, human capital formation, COVID-19, and human resource management. Here, we describe the content, survey design, and comparability of the different datasets in the SOEP-LEE2 to potential users in different disciplines of research.
Sophocle sur Netflix
(2023)
The paper focuses on two recent occurrences of a Sophoclean drama on screen, Electra in the romantical movie Marriage Story, and Philoctetes in an episode of the mainstream medical series New Amsterdam, both productions currently available on the popular streaming service Netflix. The case studies explore the mechanisms of the use of these dramas and their significance in both productions, showing that they are partly used for their “classical” authority, are deeply integrated within the scenarios, and help to design the narratives, the characters and their (social and personal) relationships.
Im Rahmen der Förderung sozialer Teilhabe von Schüler:innen im Unterricht benötigen Lehrkräfte Reflexionskompetenzen, die es ihnen ermöglichen, mit den damit verbundenen Antinomien umzugehen. Davon ausgehend wird in diesem Beitrag ein Lehr-/Lernkonzept vorgestellt, welches auf die Förderung von Lehramtsstudierenden im Sinne einer reflexiven Inklusion abzielt. Der Fokus liegt auf dem Einsatz der Methode des Lauten Denkens, welches die Denk- und Problemlösungsprozesse der Studierenden beim Schauen von Unterrichtsvideos introspektiv erfasst. Das laut Gedachte wird anschließend für Metareflexionen genutzt. Inwiefern damit (fehlende) erfahrungsbasierte und wissenschaftliche Formen pädagogischen Wissens thematisiert und prozessbegleitend begegnet werden können, um eine Entwicklung von kritisch-reflexiven Kompetenzen zu fördern, wurde in einer Pilotphase im Rahmen eines Seminars erprobt. Ergänzend wurde die Anwendung des Lauten Denkens bei einzelnen Studierenden videographiert. Dazu werden erste Ergebnisse vorgestellt und ein Ausblick auf die weitere Nutzung und Erforschung der Methode für die Förderung von Reflexionsprozessen bei Lehramtsstudierenden im Seminarkontext gegeben.

Befragungsergebnisse unter Lehramtsstudierenden belegen nur mittelmäßige Relevanzeinschätzungen hinsichtlich fachwissenschaftlicher Studieninhalte. Der Relevanzwahrnehmung in Lehr-Lern-Situationen werden indes motivations- und interessensförderliche Effekte und dadurch Einflüsse auf den Wissenserwerb zugeschrieben. Der Beitrag stellt eine auf Theorien zur Relevanzeinschätzung und einem besonderen, auf Lehr-Lern-Kontexte anwendungsbezogenen Fachwissen basierende Interventionsmaßnahme im Bachelorgeschichtsstudium an der Universität Potsdam vor: eine spezielle Vorlesung und Online-Tutorium mit Lehr-Lern-Videos, die auf die Erhöhung der Relevanzwahrnehmung von Lehramts- und Fachstudierenden abzielt. Eine fragebogengestützte Erhebung zu den Relevanzeinschätzungen der Studierenden nach dem Besuch der Lehrveranstaltung zeigt, dass alle Geschichtsstudierenden die Inhalte der Vorlesung und des Online-Tutoriums als relevant für Studium und Beruf einschätzen. Insbesondere die Inhalte des Online-Tutoriums, das anwendungsbezogenes Fachwissen vertieft, werden als berufsrelevant eingestuft, Fachstudierende könnten aber noch besser adressiert und Reflexionsfragen zur eigenen Generierung von Relevanz seitens der Studierenden eingebaut werden. Die Studie belegt insgesamt Gelingensfaktoren für die Konzeption fachwissenschaftlicher Vorlesungen, die auch an anderen Universitätsstandorten die mangelnde Relevanzeinschätzung erhöhen könnten.
“How can a course structure be redesigned based on empirical data to enhance the learning effectiveness through a student-centered approach using objective criteria?”, was the research question we asked. “Digital Twins for Virtual Commissioning of Production Machines” is a course using several innovative concepts including an in-depth practical part with online experiments, called virtual labs. The teaching-learning concept is continuously evaluated. Card Sorting is a popular method for designing information architectures (IA), “a practice of effectively organizing, structuring, and labeling the content of a website or application into a structuref that enables efficient navigation” [11]. In the presented higher education context, a so-called hybrid card sort was used, in which each participants had to sort 70 cards into seven predefined categories or create new categories themselves. Twelve out of 28 students voluntarily participated in the process and short interviews were conducted after the activity. The analysis of the category mapping creates a quantitative measure of the (dis-)similarity of the keywords in specific categories using hierarchical clustering (HCA). The learning designer could then interpret the results to make decisions about the number, labeling and order of sections in the course.
Albert Hirschman hat sein schmales, aber überaus gehaltvolles Werk über ‚Leidenschaften und Interessen‘ mit einer nachdenkenswerten Bemerkung beschlossen, die veranschaulicht, warum die Beschäftigung mit der Ideen- und Geistesgeschichte auch aus heutiger Sicht noch lohnenswert ist: „Das ist wohl das einzige, was man vom Studium der Geschichte, insbesondere der Theorie- und Geistesgeschichte erwarten darf: Nicht, dass die Streitfragen entschieden, sondern dass das Niveau der Auseinandersetzung über sie gehoben wird.“
Die im vorliegenden Band abgedruckten Beiträge wurden in den 25 Jahren zwischen 1997 und 2022 in unterschiedlichen Zeit- und Festschriften veröffentlicht und für die vorliegende Zusammenstellung behutsam überarbeitet.
Der allgegenwärtige Lehrkräftemangel führt deutschlandweit dazu, dass Stellen unbesetzt bleiben und zunehmend angehende Lehrkräfte neben ihrem Studium als Vertretungslehrkräfte (VLK) an Schulen tätig werden. Ziel des geplanten Projekts SuPPort ist es deshalb, die häufig als „unbegleitete Schulpraxiserfahrungen“ bezeichneten Vertretungslehrkrafttätigkeiten der Studierenden für die Professionalisierung der angehenden Lehrkräfte zu nutzen und langfristig die Unterrichtsqualität auch im Vertretungsunterricht zu sichern. Im Projekt wird der Professionalisierungsprozess der VLK mithilfe mehrerer digital vernetzter Angebote, die kurz-, mittel- und langfristig angelegt sind, unterstützt und begleitet. Die Unterstützungsmaßnahmen werden zielgruppenorientiert entwickelt und im Hinblick auf die Qualität für die Professionalisierung im Design-Based-Research-Ansatz in enger Verzahnung mit der Schulpraxis evaluiert und angepasst. Dabei werden insbesondere die Professionalisierungsprozesse in Bezug auf Reflexionskompetenz und Unterrichtsqualität – sowie die Studienmotivation und -zufriedenheit von Lehramtsstudierenden im Kontext unbegleiteter Praxiserfahrungen ausgewertet.
This study is dedicated to the interdependencies between digital sovereignty and sustainable digitalization, which need to be explicitly linked to an increasing degree in political discourse, academia, and societal debates. Digital skills are the prerequisites for shaping digitalization in the interest of society and sustainable development.
Die Potenziale von standardisierten Testverfahren wie VERA werden von Lehrkräften nur selten im vollen Umfang ausgeschöpft. Vor diesem Hintergrund wurde gemeinsam mit dem Institut für Schulqualität Berlin-Brandenburg auf der Grundlage von realen VERA-Ergebnissen die „VERA-Box“ entwickelt. Die Lerngelegenheit soll Erwartungen und Werte von Lehrkräften im Umgang mit Ergebnissen standardisierter Testverfahren, deren Absicht, Unterricht zukünftig unter Bezug auf solche Testergebnisse zu entwickeln, sowie den differenziellen Nutzen dieser Rückmeldeinformationen stärken. Es wurde experimentell variiert, ob zusätzlich entweder die Aufforderung enthalten war, die Relevanz standardisierter Daten für die spätere Lehrtätigkeit zu reflektieren, oder sich mit negativen Argumentationen zu VERA auseinanderzusetzen. An drei Stichproben von insgesamt 763 Lehramtsstudierenden wurde die „VERA-Box“ über drei Semester erprobt und die Wirksamkeit evaluiert. Die Ergebnisse zeigen, dass die Intention, VERA-Rückmeldungen für die eigene Unterrichtsentwicklung zu nutzen, vom ersten zum zweiten Messzeitpunkt in allen Kohorten signifikant gestärkt wurde.
Thai MOOC academy
(2023)
Thai MOOC Academy is a national digital learning platform that has been serving as a mechanism for promoting lifelong learning in Thailand since 2017. It has recently undergone significant improvements and upgrades, including the implementation of a credit bank system and a learner’s eportfolio system interconnected with the platform. Thai MOOC Academy is introducing a national credit bank system for accreditation and management, which allows for the transfer of expected learning outcomes and educational qualifications between formal education, non-formal education, and informal education. The credit bank system has five distinct features, including issuing forgery-prevented certificates, recording learning results, transferring external credits within the same wallet, accumulating learning results, and creating a QR code for verification purposes. The paper discusses the features and future potential of Thai MOOC Academy, as it is extended towards a sandbox for the national credit bank system in Thailand.
Long COVID patients show symptoms, such as fatigue, muscle weakness and pain. Adequate diagnostics are still lacking. Investigating muscle function might be a beneficial approach. The holding capacity (maximal isometric Adaptive Force; AFisomax) was previously suggested to be especially sensitive for impairments. This longitudinal, non-clinical study aimed to investigate the AF in long COVID patients and their recovery process. AF parameters of elbow and hip flexors were assessed in 17 patients at three time points (pre: long COVID state, post: immediately after first treatment, end: recovery) by an objectified manual muscle test. The tester applied an increasing force on the limb of the patient, who had to resist isometrically for as long as possible. The intensity of 13 common symptoms were queried. At pre, patients started to lengthen their muscles at ~50% of the maximal AF (AFmax), which was then reached during eccentric motion, indicating unstable adaptation. At post and end, AFisomax increased significantly to ~99% and 100% of AFmax, respectively, reflecting stable adaptation. AFmax was statistically similar for all three time points. Symptom intensity decreased significantly from pre to end. The findings revealed a substantially impaired maximal holding capacity in long COVID patients, which returned to normal function with substantial health improvement. AFisomax might be a suitable sensitive functional parameter to assess long COVID patients and to support therapy process
Background Anxiety and depressive disorders share common features of mood dysfunctions. This has stimulated interest in transdiagnostic dimensional research as proposed by the Research Domain Criteria (RDoC) approach by the National Institute of Mental Health (NIMH) aiming to improve the understanding of underlying disease mechanisms. The purpose of this study was to investigate the processing of RDoC domains in relation to disease severity in order to identify latent disorder-specific as well as transdiagnostic indicators of disease severity in patients with anxiety and depressive disorders.
Methods Within the German research network for mental disorders, 895 participants (n = 476 female, n = 602 anxiety disorder, n = 257 depressive disorder) were recruited for the Phenotypic, Diagnostic and Clinical Domain Assessment Network Germany (PD-CAN) and included in this cross-sectional study. We performed incremental regression models to investigate the association of four RDoC domains on disease severity in patients with affective disorders: Positive (PVS) and Negative Valance System (NVS), Cognitive Systems (CS) and Social Processes (SP).
Results The results confirmed a transdiagnostic relationship for all four domains, as we found significant main effects on disease severity within domain-specific models (PVS: & beta; = -0.35; NVS: & beta; = 0.39; CS: & beta; = -0.12; SP: & beta; = -0.32). We also found three significant interaction effects with main diagnosis showing a disease-specific association.
Limitations The cross-sectional study design prevents causal conclusions. Further limitations include possible outliers and heteroskedasticity in all regression models which we appropriately controlled for.
Conclusion Our key results show that symptom burden in anxiety and depressive disorders is associated with latent RDoC indicators in transdiagnostic and disease-specific ways.
This paper presents a new design for MOOCs for professional development of skills needed to meet the UN Sustainable Development Goals – the CoMOOC or Co-designed Massive Open Online Collaboration. The CoMOOC model is based on co-design with multiple stakeholders including end-users within the professional communities the CoMOOC aims to reach. This paper shows how the CoMOOC model could help the tertiary sector deliver on the UN Sustainable Development Goals (UNSDGs) – including but not limited to SDG 4 Education – by providing a more effective vehicle for professional development at a scale that the UNSDGs require. Interviews with professionals using MOOCs, and design-based research with professionals have informed the development of the Co-MOOC model. This research shows that open, online, collaborative learning experiences are highly effective for building professional community knowledge. Moreover, this research shows that the collaborative learning design at the heart of the CoMOOC model is feasible cross-platform Research with teachers working in crisis contexts in Lebanon, many of whom were refugees, will be presented to show how this form of large scale, co-designed, online learning can support professionals, even in the most challenging contexts, such as mass displacement, where expertise is urgently required.
The heat is on

Climate conditions severely impact the activity and, consequently, the fitness of wildlife species across the globe. Wildlife can respond to new climatic conditions, but the pace of human-induced change limits opportunities for adaptation or migration. Thus, how these changes affect behavior, movement patterns, and activity levels remains unclear. In this study, we investigate how extreme weather conditions affect the activity of European hares (Lepus europaeus) during their peak reproduction period. When hares must additionally invest energy in mating, prevailing against competitors, or lactating, we investigated their sensitivities to rising temperatures, wind speed, and humidity. To quantify their activity, we used the overall dynamic body acceleration (ODBA) calculated from tri-axial acceleration measurements of 33 GPS-collared hares. Our analysis revealed that temperature, humidity, and wind speed are important in explaining changes in activity, with a strong response for high temperatures above 25 & DEG;C and the highest change in activity during temperature extremes of over 35 & DEG;C during their inactive period. Further, we found a non-linear relationship between temperature and activity and an interaction of activity changes between day and night. Activity increased at higher temperatures during the inactive period (day) and decreased during the active period (night). This decrease was strongest during hot tropical nights. At a stage of life when mammals such as hares must substantially invest in reproduction, the sensitivity of females to extreme temperatures was particularly pronounced. Similarly, both sexes increased their activity at high humidity levels during the day and low wind speeds, irrespective of the time of day, while the effect of humidity was stronger for males. Our findings highlight the importance of understanding the complex relationships between extreme weather conditions and mammal behavior, critical for conservation and management. With ongoing climate change, extreme weather events such as heat waves and heavy rainfall are predicted to occur more often and last longer. These events will directly impact the fitness of hares and other wildlife species and hence the population dynamics of already declining populations across Europe.
Sulfur is an important element that is incorporated into many biomolecules in humans. The incorporation and transfer of sulfur into biomolecules is, however, facilitated by a series of different sulfurtransferases. Among these sulfurtransferases is the human mercaptopyruvate sulfurtransferase (MPST) also designated as tRNA thiouridine modification protein (TUM1). The role of the human TUM1 protein has been suggested in a wide range of physiological processes in the cell among which are but not limited to involvement in Molybdenum cofactor (Moco) biosynthesis, cytosolic tRNA thiolation and generation of H2S as signaling molecule both in mitochondria and the cytosol. Previous interaction studies showed that TUM1 interacts with the L-cysteine desulfurase NFS1 and the Molybdenum cofactor biosynthesis protein 3 (MOCS3). Here, we show the roles of TUM1 in human cells using CRISPR/Cas9 genetically modified Human Embryonic Kidney cells. Here, we show that TUM1 is involved in the sulfur transfer for Molybdenum cofactor synthesis and tRNA thiomodification by spectrophotometric measurement of the activity of sulfite oxidase and liquid chromatography quantification of the level of sulfur-modified tRNA. Further, we show that TUM1 has a role in hydrogen sulfide production and cellular bioenergetics.
Development of self-concept and task interest has been shown to be affected by social comparison processes in a variety of cross-sectional studies. A potential explanation for these effects is an effect of social comparative performance feedback on an individual’s self-evaluation of performance, which in turn influences development of self-concept and task interest. There are, however, only few studies addressing this topic with experimental designs. This study was aimed at closing this research gap by experimentally manipulating social comparative performance. Feedback given was based on 2 × 2 experimental conditions: social position (high vs. low) and average performance of the reference group (high vs. low). Results show a strong effect of social position on self-evaluation of performance and smaller effects on self-concept and task interest.
