TY - JOUR A1 - Scheffler, Christiane A1 - Hermanussen, Michael T1 - What does stunting tell us? 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.

JF - Environmental research letters : ERL N2 - Based on suggested interactions of potential tipping elements in the Earth's climate and in ecological systems, tipping cascades as possible dynamics are increasingly discussed and studied. The activation of such tipping cascades would impose a considerable risk for human societies and biosphere integrity. However, there are ambiguities in the description of tipping cascades within the literature so far. Here we illustrate how different patterns of multiple tipping dynamics emerge from a very simple coupling of two previously studied idealized tipping elements. In particular, we distinguish between a two phase cascade, a domino cascade and a joint cascade. A mitigation of an unfolding two phase cascade may be possible and common early warning indicators are sensitive to upcoming critical transitions to a certain degree. In contrast, a domino cascade may hardly be stopped once initiated and critical slowing down-based indicators fail to indicate tipping of the following element. These different potentials for intervention and anticipation across the distinct patterns of multiple tipping dynamics should be seen as a call to be more precise in future analyses of cascading dynamics arising from tipping element interactions in the Earth system.

BT - a model-based statistical approach JF - Hydrology and earth system sciences : HESS N2 - This study analyzes the influence of local and regional climatic factors on the stable isotopic composition of rainfall in the Vietnamese Mekong Delta (VMD) as part of the Asian monsoon region. It is based on 1.5 years of weekly rainfall samples. In the first step, the isotopic composition of the samples is analyzed by local meteoric water lines (LMWLs) and single-factor linear correlations. Additionally, the contribution of several regional and local factors is quantified by multiple linear regression (MLR) of all possible factor combinations and by relative importance analysis. This approach is novel for the interpretation of isotopic records and enables an objective quantification of the explained variance in isotopic records for individual factors. In this study, the local factors are extracted from local climate records, while the regional factors are derived from atmospheric backward trajectories of water particles. The regional factors, i.e., precipitation, temperature, relative humidity and the length of backward trajectories, are combined with equivalent local climatic parameters to explain the response variables delta O-18, delta H-2, and d-excess of precipitation at the station of measurement. The results indicate that (i) MLR can better explain the isotopic variation in precipitation (R-2 = 0.8) compared to single-factor linear regression (R-2 = 0.3); (ii) the isotopic variation in precipitation is controlled dominantly by regional moisture regimes (similar to 70 %) compared to local climatic conditions (similar to 30 %); (iii) the most important climatic parameter during the rainy season is the precipitation amount along the trajectories of air mass movement; (iv) the influence of local precipitation amount and temperature is not sig-nificant during the rainy season, unlike the regional precipitation amount effect; (v) secondary fractionation processes (e.g., sub-cloud evaporation) can be identified through the d-excess and take place mainly in the dry season, either locally for delta O-18 and delta H-2, or along the air mass trajectories for d-excess. The analysis shows that regional and local factors vary in importance over the seasons and that the source regions and transport pathways, and particularly the climatic conditions along the pathways, have a large influence on the isotopic composition of rainfall. Although the general results have been reported qualitatively in previous studies (proving the validity of the approach), the proposed method provides quantitative estimates of the controlling factors, both for the whole data set and for distinct seasons. Therefore, it is argued that the approach constitutes an advancement in the statistical analysis of isotopic records in rainfall that can supplement or precede more complex studies utilizing atmospheric models. Due to its relative simplicity, the method can be easily transferred to other regions, or extended with other factors. The results illustrate that the interpretation of the isotopic composition of precipitation as a recorder of local climatic conditions, as for example performed for paleorecords of water isotopes, may not be adequate in the southern part of the Indochinese Peninsula, and likely neither in other regions affected by monsoon processes. However, the presented approach could open a pathway towards better and seasonally differentiated reconstruction of paleoclimates based on isotopic records.

JF - Climate of the past : CP N2 - Ice-core-based records of isotopic composition are a proxy for past temperatures and can thus provide information on polar climate variability over a large range of timescales. However, individual isotope records are affected by a multitude of processes that may mask the true temperature variability. The relative magnitude of climate and non-climate contributions is expected to vary as a function of timescale, and thus it is crucial to determine those temporal scales on which the actual signal dominates the noise. At present, there are no reliable estimates of this timescale dependence of the signal-to-noise ratio (SNR). Here, we present a simple method that applies spectral analyses to stable-isotope data from multiple cores to estimate the SNR, and the signal and noise variability, as a function of timescale. The method builds on separating the contributions from a common signal and from local variations and includes a correction for the effects of diffusion and time uncertainty. We apply our approach to firn-core arrays from Dronning Maud Land (DML) in East Antarctica and from the West Antarctic Ice Sheet (WAIS). For DML and decadal to multi-centennial timescales, we find an increase in the SNR by nearly 1 order of magnitude (similar to 0.2 at decadal and similar to 1.0 at multi-centennial scales). The estimated spectrum of climate variability also shows increasing variability towards longer timescales, contrary to what is traditionally inferred from single records in this region. In contrast, the inferred variability spectrum for WAIS stays close to constant over decadal to centennial timescales, and the results even suggest a decrease in SNR over this range of timescales. We speculate that these differences between DML and WAIS are related to differences in the spatial and temporal scales of the isotope signal, highlighting the potentially more homogeneous atmospheric conditions on the Antarctic Plateau in contrast to the marine-influenced conditions on WAIS. In general, our approach provides a methodological basis for separating local proxy variability from coherent climate variations, which is applicable to a large set of palaeoclimate records.

Previous studies have shown that this test fits better in Western cultures. The idea of a social ladder itself and ranking oneself “higher” or “lower” is a concept that accords to the Western thinking. Objectives We hypothesize that in a culture where only the elites have adapted to a Western lifestyle, the test results reflect a higher level of accuracy for this stratum. We also expect that self-perception differs per sex. Sample and Methods We implemented the Ladder Test in a study of Indonesian schoolchildren aged between 5 and 13 years (boys N = 369, girls N= 364) from non-private and private schools in Kupang in 2020. Results Our analysis showed that the Ladder Test results were according to the Western expectations only for the private school, as the Ladder Scores significantly decreased with age (LM: p = 0.04). The Ladder Test results are best explained by “Education Father” for the non-private school pupils (p = 0.01) and all boys (p = 0.04), by “School Grades” for the private school cohort (p = 0.06) and by “Household Score” for girls (p =0.09). Conclusion This finding indicates that the concept of ranking oneself “high” or “low” on a social ladder is strongly implicated with Western ideas. A ladder implies social movement by “climbing” up or down. According to that, reflection of self-perception is influenced by culture.

However, a systematic summary of the effectiveness of online interventions for people experiencing bereavement is still missing. Objective: A systematic literature search was conducted by four reviewers who reviewed and meta-analytically summarized the evidence for web-based interventions for bereaved people. Methods: Systematic searches (PubMed, Web of Science, PsycInfo, PsycArticles, Medline, and CINAHL) resulted in seven randomized controlled trials (N= 1,257) that addressed adults having experienced bereavement using internet-based interventions. We used random effects models to summarize treatment effects for between-group comparisons (treatmentvs.control at post) and stability over time (postvs.follow-up). Results: All web-based interventions were based on cognitive behavioral therapy (CBT). In comparison with control groups, the interventions showed moderate (g= .54) to large effects (g= .86) for symptoms of grief and posttraumatic stress disorder (PTSD), respectively. The effect for depression was small (g= .44). All effects were stable over time. A higher number of treatment sessions achieved higher effects for grief symptoms and more individual feedback increased effects for depression. Other moderators (i.e.dropout rate, time since loss, exposure) did not significantly reduce moderate degrees of heterogeneity between the studies. Limitations: The number of includable studies was low in this review resulting to lower power for moderator analyses in particular. Conclusions: Overall, the results of web-based bereavement interventions are promising, and its low-threshold approach might reduce barriers to bereavement care. Nonetheless, future research should further examine potential moderators and specific treatment components (e.g.exposure, feedback) and compare interventions with active controls.

Their economic repercussions along the supply and trade network also affect remote economies that are not directly affected. We here simulate possible global repercussions on consumption for the example case of Hurricane Sandy in the US (2012) using the shock-propagation model Acclimate. The modeled shock yields a global three-phase ripple: an initial production demand reduction and associated consumption price decrease, followed by a supply shortage with increasing prices, and finally a recovery phase. Regions with strong trade relations to the US experience strong magnitudes of the ripple. A dominating demand reduction or supply shortage leads to overall consumption gains or losses of a region, respectively. While finding these repercussions in historic data is challenging due to strong volatility of economic interactions, numerical models like ours can help to identify them by approaching the problem from an exploratory angle, isolating the effect of interest. For this, our model simulates the economic interactions of over 7000 regional economic sectors, interlinked through about 1.8 million trade relations. Under global warming, the wave-like structures of the economic response to major hurricanes like the one simulated here are likely to intensify and potentially overlap with other weather extremes.

The dataset includes rainfall data from 12 rain gauges distributed within the study area complemented by meteorological data of 12 official meteo-stations. It comprises discharge data derived from water stage measurements as well as suspended sediment concentrations (SSCs) at six gauging stations of the River Isabena and its sub-catchments. Soil spectroscopic data from 351 suspended sediment samples and 152 soil samples were collected to characterize sediment source regions and sediment properties via fingerprinting analyses. The Isabena catchment (445 km(2)) is located in the southern central Pyrenees ranging from 450 m to 2720 m a.s.l.; together with a pronounced topography, this leads to distinct temperature and precipitation gradients. The River Isabena shows marked discharge variations and high sediment yields causing severe siltation problems in the downstream Barasona Reservoir. The main sediment source is badland areas located on Eocene marls that are well connected to the river network. The dataset features a comprehensive set of variables in a high spatial and temporal resolution suitable for the advanced process understanding of water and sediment fluxes, their origin and connectivity and sediment budgeting and for the evaluation and further development of hydro-sedimentological models in Mediterranean mesoscale mountainous catchments.

N2 - The student teaching semester, allowing the pre-service teachers to spend several months at a school, have become an important part of practical teacher training during university studies. The manifold aims include capacity building in teacher competences as well as providing an opportunity to review one’s career choice. At the same time, current studies show that practical teacher training tends to leave many of its aims unfulfilled. So far, however, the research focus was not on learning opportunities during the student teaching semester. To find out how pre-service teachers judge learning outcomes and opportunities, we interviewed seven pre-service teachers after the end of their student teaching semester. The results show that the pre-service teachers believe they developed their teaching competences and got to know themselves as „teachers“. To them, talking to their mentor teacher presented itself as the most meaningful learning opportunity.

Jahrhundert JF - PaRDeS : Zeitschrift der Vereinigung für Jüdische Studien = Transformative Translations in Jewish History and Culture N2 - The paper investigates how cultural and social capital were passed down to the next generations via letters of recommendation. Focusing on fathers recommending their sons to German Jewish banker Gerson (von) Bleichröder, the paper asks how father-son relations were described and which role equivalent backgrounds, especially in terms of Jewishness and social standing, played in this process. Mainly discussed are four different patriarchs approaching Bleichröder on behalf of their sons to further their careers. Making use of methods such as historical network analysis and semantic analysis the paper introduces the letters of recommendation as a complex yet promising practice in order to maintain, strengthen and even further the family’s (social) capital over generational changes. The paper finds trust and tradition to be crucial for successful recommendations. Situated at a liminal point of economic and personal spheres, recommendations shed new light on crucial questions of 19th-century Jewish history, such as acculturation and distinctiveness as well as on intra-familial dynamics in the face of profound social transformation.

Dieser Beitrag geht der Frage nach, welche Kompetenzen aus beruflichen Vorqualifikationen bei Informatikstudierenden existieren und wie diese in Bezug zu Anerkennungsoptionen gesetzt werden können. Betrachtet werden: die pauschale Anerkennung, die auf erworbenen Zertifikaten beruht; die individuelle Anerkennung, bei der individuell erworbene Kompetenzen nachgewiesen werden; die Adaption von individuellen Lernwegen, die Teilkompetenzen der Studierenden berücksichtigt. Es wird eine Interviewstudie vorgestellt, in der Kompetenzen für ein Sample von Informatikstudierenden mit Vorqualifikation als Fachinformatiker/in erhoben und eine Zuordnung zu den Anerkennungsoptionen vorgenommen wurde. Für die präzisere Gestaltung von Anerkennungsprozessen und zur kritischen Reflexion der eingesetzten hochschuldidaktischen Konzepte wurde eine empirische Basis geschaffen. Die vorhandenen Konzepte richten sich traditionell an Abiturienten/ innen mit sehr geringem Informatikhintergrund und berücksichtigen die tatsächlich existierende Heterogenität der Studienanfänger/innen nicht angemessen. Die Ergebnisse zeigen, dass die Befragten aus ihrer Vorqualifikation relevante fachliche Kompetenzen mitbringen, die mit den Anerkennungsoptionen korrespondieren und deren Weiterentwicklung dienen können. Darüber hinaus werden aus überfachlichen Kompetenzen wie Selbststeuerungskompetenzen weitere Erkenntnisse zur Studiengestaltung gewonnen.

Alexander von Humboldt bemerkte und beschrieb um die Wende zum 19. Jahrhundert eine fundamentale Epochenschwelle, die er im Vorwort zu seinen Vues des Cordillères et Monumens des Peuples Indigènes de l’Amérique als eine „glückliche Revolution“ bezeichnete. Diese Revolution schloss für Humboldt auch die Tatsache mit ein, die Aufklärung nicht als eine rein europäische, sondern als eine transatlantische und weltumspannende philosophische Bewegung zu verstehen. N2 - This article discusses the epistemic changes and transformations that led from the famous Voyages around the world to the explorations not only of the coastlines but of the interiors of continents and islands in the light of what has been calles “the Berlin Debate about the New World”. In his Vues des Cordillères et Monumens des Peuples Indigènes de l’Amérique, Alexander von Humboldt detected a fundamental epistemic shift that he coined as “the happy revolution”. This revolution around 1800 included, for Humboldt, a new understanding of the term “Aufklärung” no more reduced to European dimensions but opening the term Lumières towards a transatlantic and even world-wide comprehension. N2 - Cet article présente les changements épistémiques qui menèrent des fameux Voyages autour du monde aux voyages d’explorations non plus seulement des régions littorales mais surtout de l’intérieur des pays visités. Afin de mieux comprendre ces transformations fondamentales, il est indispensable de recourir au fameux «Débat Berlinois sur le Nouveau Monde» qui opposait les philosophes Européens aux philosophes de l’hémisphère américain. Dans la préface à ses Vues des Cordillères et Monumens des Peuples Indigènes de l’Amérique, Alexandre de Humboldt detecta, d’une façon brillante, cette transformation épistémologique fondamentale qu’il traita de «révolution heureuse», tout en intégrant les Lumières du Nouveau Monde dans sa conception d’une République des Lettres vraiment internationale.

Their hands-free interface and growing capabilities have a wide range of applications in health care, covering off-clinic education, health monitoring, and communication. However, conflicting factors, such as patient safety and privacy concerns, make it difficult to foresee the further development of VIPAs in health care.
Objective: This study aimed to develop a plausible scenario for the further development of VIPAs in health care to support decision making regarding the procurement of VIPAs in health care organizations. Methods: We conducted a two-stage Delphi study with an internationally recruited panel consisting of voice assistant experts, medical professionals, and representatives of academia, governmental health authorities, and nonprofit health associations having expertise with voice technology. Twenty projections were formulated and evaluated by the panelists. Descriptive statistics were used to derive the desired scenario.
Results: The panelists expect VIPAs to be able to provide solid medical advice based on patients' personal health information and to have human-like conversations. However, in the short term, voice assistants might neither provide frustration-free user experience nor outperform or replace humans in health care. With a high level of consensus, the experts agreed with the potential of VIPAs to support elderly people and be widely used as anamnesis, informational, self-therapy, and communication tools by patients and health care professionals. Although users' and governments' privacy concerns are not expected to decrease in the near future, the panelists believe that strict regulations capable of preventing VIPAs from providing medical help services will not be imposed.
Conclusions: According to the surveyed experts, VIPAs will show notable technological development and gain more user trust in the near future, resulting in widespread application in health care. However, voice assistants are expected to solely support health care professionals in their daily operations and will not be able to outperform or replace medical staff.

The data recording setup and data analysis pipelines are both crucial aspects to effectively obtain relevant information from participants. Therefore, we performed a systematic review to provide a high-level overview of practices across various neurological disorders and highlight emerging trends. PRISMA-based literature searches were conducted through PubMed, Web of Science, and IEEE Xplore to identify publications in which original (i.e., newly recorded) datasets were collected. Disorders of interest were psychiatric as well as neurodegenerative disorders, such as bipolar disorder, depression, and stress, as well as amyotrophic lateral sclerosis amyotrophic lateral sclerosis, Alzheimer's, and Parkinson's disease, and speech impairments (aphasia, dysarthria, and dysphonia). Of the 43 retrieved studies, Parkinson's disease is represented most prominently with 19 discovered datasets. Free speech and read speech tasks are most commonly used across disorders. Besides popular feature extraction toolkits, many studies utilise custom-built feature sets. Correlations of acoustic features with psychiatric and neurodegenerative disorders are presented. In terms of analysis, statistical analysis for significance of individual features is commonly used, as well as predictive modeling approaches, especially with support vector machines and a small number of artificial neural networks. An emerging trend and recommendation for future studies is to collect data in everyday life to facilitate longitudinal data collection and to capture the behavior of participants more naturally. Another emerging trend is to record additional modalities to voice, which can potentially increase analytical performance.

We investigated whether the developmental decrease previously attested in anticipatory coarticulation, as well as the relation between coarticulatory degree and the consonantal context, also characterize carryover coarticulation. Sixty-two children and 13 adults, all native speakers of German, were recruited according to five age cohorts: three-year-olds, four-year-olds, five-year-olds, seven-year-olds, and adults. Tongue movements during the production of ə.CV.Cə utterances (C = /b, d, g/, V = /i, y, e, a, o, u/) were recorded with ultrasound. We measured vowel-induced horizontal displacement of the tongue dorsum within the last syllable and compared the resulting coarticulatory patterns between age cohorts and consonantal contexts. Results indicate that the degree of vocalic carryover coarticulation decreases with age. Vocalic prominence within an utterance as well as its change across childhood depended on the postvocalic consonant’s articulatory demands for the tongue dorsum (i.e., its coarticulatory resistance): Low resistant /b/ and /g/ allowed for more vocalic perseveration and a continuous decrease, while the highly resistant /d/ displayed lower coarticulation degrees and discontinuous effects. These findings parallel those in anticipation suggesting a similar organization of anticipatory and carryover coarticulation. Implications for theories of speech production are discussed.

N2 - Founded in 2013, OpenClassrooms is a French online learning company that offers both paid courses and free MOOCs on a wide range of topics, including computer science and education. In 2021, in partnership with the EDA research unit, OpenClassrooms shared a database to solve the problem of how to increase persistence in their paid courses, which consist of a series of MOOCs and human mentoring. Our statistical analysis aims to identify reasons for dropouts that are due to the course design rather than demographic predictors or external factors.We aim to identify at-risk students, i.e. those who are on the verge of dropping out at a specific moment. To achieve this, we use learning analytics to characterize student behavior. We conducted data analysis on a sample of data related to the “Web Designers” and “Instructional Design” courses. By visualizing the student flow and constructing speed and acceleration predictors, we can identify which parts of the course need to be calibrated and when particular attention should be paid to these at-risk students.

In this tissue, Wg (Drosophila Wnt-I) is presented on the apical surface of its source cells before being internalized into the endosomal pathway. Long-range Wg secretion and spread depend on secondary secretion from endosomal compartments, but the exact post-endocytic fate of Wg is poorly understood. Here, we summarize and present three protocols for the immunofluorescencebased visualization and quantitation of different pools of intracellular and extracellular Wg in WID: (1) steady-state extracellular Wg; (2) dynamic Wg trafficking inside endosomal compartments; and (3) dynamic Wg release to the cell surface. Using a genetic driver system for gene manipulation specifically at the posterior part of the WID (EnGal4) provides a robust internal control that allows for direct comparison of signal intensities of control and manipulated compartments of the same WID. Therefore, it also circumvents the high degree of staining variability usually associated with whole-tissue samples. In combination with the genetic manipulation of Wg pathway components that is easily feasible in Drosophila, these methods provide a tool-set for the dissection of secretory Wg trafficking and can help us to understand how Wnt proteins travel along endosomal compartments for short-and long-range signal secretion.

Objective: We will provide an overview of the annual publication numbers in this field and the most productive and influential countries, journals, and authors, as well as the most used, most co-occurring, and most recent keywords. Methods: Based on a data set of 356 publications and 20,363 citations derived from Web of Science, we conducted a bibliometric analysis using BibExcel, HistCite, and VOSviewer. Results: The strongest growth in publications occurred in 2020, accounting for 29.49% of all publications so far. The most productive countries are the United States, the United Kingdom, and Spain; the most influential countries are the United States, Canada, and the United Kingdom. The most productive journals are the Journal of Medical Internet Research (JMIR), JMIR Serious Games, and the Games for Health Journal; the most influential journals are Patient Education and Counselling, Medical Education, and Quality of Life Research. The most productive authors are Riva, del Piccolo, and Schwebel; the most influential authors are Finset, del Piccolo, and Eide. The most frequently occurring keywords other than “virtual” and “reality” are “training,” “trial,” and “patients.” The most relevant research themes are communication, education, and novel treatments; the most recent research trends are fitness and exergames. Conclusions: The analysis shows that the field has left its infant state and its specialization is advancing, with a clear focus on patient usability.

Migrants tend to adjust in height to their host communities. Objectives: Social-Economic-Political-Emotional (SEPE) factors influence growth. We hypothesized that Vietnamese young adult migrants in Germany (1) are taller than their parents, (2) are as tall as their German peers, and (3) are as tall as predicted by height expectation at age 13 years. Sample: The study was conducted in 30 male and 54 female Vietnamese migrants (mean age 26.23 years. SD=4.96) in Germany in 2020. Methods: Information on age, sex, body height, school and education, job, height and ethnicity of best friend, migration history and cultural identification, parental height and education, and recalled information on their personal height expectations at age 13 years were obtained by questionnaire. The data were analyzed by St. Nicolas House Analysis (SNHA) and multiple regression. Results: Vietnamese young adults are taller than their parents (females 3.85cm, males 7.44cm), but do not fully attain height of their German peers. The body height is positively associated with the height of best friend (p < 0.001), the height expectation at age 13 year (p < 0.001), and father’s height (p=0.001). Conclusion: Body height of Vietnamese migrants in Germany reflects competitive growth and strategic growth adjustments. The magnitude of this intergenerational trend supports the concept that human growth depends on SEPE factors.

T3 - Built environment city studies N2 - This book explores and debates the urban transformations that have taken place in Vienna over the past 30 years and their consequences in policy fields such as labour and housing, political and social participation and the environment. Historically, European cities have been characterised by a strong association between social cohesion, quality of life, economic ambition and a robust State. Vienna is an excellent example for that. In more recent years, however, cities were pressured to change policy principles and mechanisms in the context of demographic shifts, post-industrial transformations and welfare recalibration which have led to worsened social conditions in many cities. Each chapter in this volume discusses Vienna's responses to these pressures in key policy arenas, looking at outcomes from the context-specific local arrangements. Against a theoretical framework debating the European city as a model of inclusion and social justice, authors explore the local capacity to innovate urban policies and to address new social risks, while paying attention to potential trade-offs. The book questions and assesses the city's resilience using time series and an institutional analysis of four key dimensions that characterise the European city model within the context of post-industrial transition: redistribution, recognition, representation and sustainability. It offers a multiscalar perspective of urban governance through labour, housing, participatory and environmental policies, bringing together different levels and public policy types.

In striking contrast to its neighboring plates, Victoria rotates counterclockwise with respect to Nubia. The underlying cause of this distinctive rotation has remained elusive so far. Using 3D numerical models, we investigate the role of pre-existing lithospheric heterogeneities in continental microplate rotation. We find that Victoria's rotation is primarily controlled by the distribution of rheologically stronger zones that transmit the drag of the major plates to the microplate and of the mechanically weaker mobile belts surrounding Victoria that facilitate rotation. Our models reproduce Victoria's GPS-derived counterclockwise rotation as well as key complexities of the regional tectonic stress field. These results reconcile competing ideas on the opening of the rift system by highlighting differences in orientation of the far-field divergence, local extension, and the minimum horizontal stress. One of the largest continental microplates on Earth is situated in the center of the East African Rift System, and oddly, the Victoria microplate rotates counterclockwise with respect to the neighboring African tectonic plate. Here, the authors' modelling results suggest that Victoria microplate rotation is caused by edge-driven lithospheric processes related to the specific geometry of rheologically weak and strong regions.

Da diese häufig weniger Einfluss auf den Verlauf des Schulalltags von Lehrpersonen haben als externalisierendes Erleben und Verhalten von Kindern, werden internalisierende Verhaltensbesonderheiten von Kindern häufig seltener wahrgenommen und seltener als pädagogisch relevant eingestuft. Daher erfahren diese Kinder oft weniger förderdiagnostische Unterstützung.

N2 - This article discusses diagnostic competences of pre-service teachers with a particular focus on dimensions of internalising behaviour difficulties. In comparison to externalising behaviour difficulties, internalising behaviour difficulties are more difficult for teachers to diagnose because children afflicted by them tend to show only little disruptive behaviour in class. Hence, children with internalising behaviour also receive less support. The goal of the supervised internship at school (Psychodiagnostisches Praktikum; PDP) is the development of each student’s diagnostic competences with a focus on internalising behaviour. The internship for primary school teacher students with the focus on inclusion consists of practical experiences with associated seminar sessions in which the students are preparing and conducting diagnostical surveys. Changes in student’s self-reported diagnostic competences are evaluated using a self-developed questionnaire. This article presents the conception and development of this questionnaire as well as first results of the pilot study.

Die Kooperation besteht aus zwei Seminaren. Während andere Fächer (u. a. Mathematik, Naturwissenschaften, Geschichte) bereits in der ersten Phase des PSI-Projekts Erkenntnisse zur Erfassung des erweiterten Fachwissens für den schulischen Kontext (eFWsK) vorgelegt haben, widmet sich die Englischdidaktik der Strukturierung des Professionswissens im Fach erst seit wenigen Jahren. Der Versuch, das eFWsK-Modell auf das Fach Englisch zu übertragen, stellt die Disziplin aus diversen Gründen vor eine besondere Herausforderung. Am Beispiel zweier verzahnter Lehrveranstaltungen zur Entwicklung von Diagnosefähigkeiten angehender Lehrkräfte zur Beurteilung von Sprechleistungen wird erörtert, welches fachwissenschaftliche und fachdidaktische Wissen durch die Verzahnung der beiden Disziplinen erworben wird. Zugleich werden offene Fragen diskutiert, die sich aus der Kooperation mit Blick auf eine Systematisierung relevanter fachwissenschaftlicher Inhalte für das Lehramtsstudium ergeben. Im Ausblick wird erörtert, warum eine Systematisierung des fachlichen Professionswissens mittels einer Delphi-Studie im Fach Englisch sinnvoll erscheint. N2 - This article presents a university course cooperation on the interlocking of linguistics and pedagogy in the teacher training program English at the University of Potsdam. While other subjects (including mathematics, natural sciences, history) have already introduced insights into recording extended subject knowledge for the school context (eFWsK) in the first phase of the PSI project, English didactics has only been dedicated to structuring professional knowledge in the subject for a few years. Attempting to apply the eFWsK model to the subject English poses a particular challenge to the discipline for a variety of reasons. Using a course on developing prospective teachers’ diagnostic skills for assessing speaking performance as an example, this paper discusses the content knowledge and pedagogical content knowledge that is acquired through the interlocking of the two disciplines. At the same time, open questions are discussed that arise from the cooperation regarding a systematization of relevant professional knowledge for the teacher training program. The outlook substantiates why it seems useful to systemize content knowledge in the subject English with the Delphi method.

H.E.S.S. observations were accompanied or preceded by multiwavelength observations with Fermi/LAT, XRT and UVOT onboard the Swift satellite, and ATOM. Based on an extrapolation of the Fermi/LAT spectrum towards the VHE gamma-ray regime, we deduce a 95 per cent confidence level upper limit on the unknown redshift of KUV 00311-1938 of z < 0.98 and of PKS 1440-389 of z < 0.53. When combined with previous spectroscopy results, the redshift of KUV 00311-1938 is constrained to 0.51 <= z < 0.98 and of PKS 1440-389 to 0.14 (sic) z < 0.53.

In den Modernisierungsprozessen stehen derzeit zwei Segmente besonders im Fokus: Digitalisierung und Partizipation. Digitalisierung geht heute weit über die ursprünglich mit diesem Stichwort angesprochene Umwandlung analoger Daten in elektronische Datenformate hinaus. Die Programmatik der Digitalisierung zielt auf den möglichst umfassenden Einsatz elektronischer Informations- und Kommunikationstechniken zur Unterstützung, Beschleunigung, Rationalisierung und in Teilen auch Ersetzung von herkömmlichen Verwaltungsabläufen mit der Perspektive auf eine Transformation und Durchdringung sowohl des gesamten Verwaltungshandelns als auch der gesamten Verwaltungsorganisation. Demgegenüber meint Partizipation nach gängigem Verständnis die Beteiligung von Bürgern und anderen gesellschaftlichen Akteuren an politischen Willensbildungs- und Entscheidungsprozessen. In spezifisch administrativem Zusammenhang geht es vor allem um die Einbindung von Bürgern in Entscheidungsprozesse der Verwaltung und um die Aktivierung der Zivilgesellschaft, die Erschließung bürgerschaftlichen Engagements sowie gesellschaftlicher Ressourcen für die Erfüllung von Verwaltungsaufgaben – und dies alles mit dem Ziel einer Verbesserung der Legitimität und Qualität öffentlicher Verwaltung. Die beiden Modernisierungsansätze stehen nicht unverbunden nebeneinander. Vielmehr gehen sie nicht selten ineinander über. Beispiele dafür sind die Bereitstellung von Optionen zu elektronischer Stellung und Bearbeitung von Anträgen sowie von elektronischen Plattformen für die Bürgerpartizipation. An diesen Themenfeldern der Verwaltungsmodernisierung setzt der Tagungsband an. Er dokumentiert den Gedankenaustausch über Digitalisierungs- und Partizipationsprozesse zwischen polnischen und deutschen Verwaltungsrechtswissenschaftlern auf einer Tagung, die im Dezember 2019 an der Universität Potsdam stattgefunden hat.

The cross-correlation is done by probing intensity and position changes of superlattice Bragg peaks caused by photoexcitation of coherent phonons. This approach is applicable for a wide range of X-ray photon energies as well as for a broad range of excitation wavelengths and requires no external fields or changes of temperature.

N2 - This article examines the possibilities of a systematic networking of German literature studies and didactics in university teaching. To this end, a total of twelve seminar cooperations were carried out within the framework of a project, in each of which a subject-specific seminar cooperated with a didactic seminar. The evaluation of these cooperations, which is based on a discussion of existing problems in the German teacher training program as outlined in the research literature and current comparable projects, is qualitative-analytical in nature and is based on guided interviews with the lecturers concerned. This detailed reflection on the cooperation seminars reveals, on the one hand, problems of the cooperation between subject science and didactics. On the other hand, on this basis, possible conditions for the success of effective cooperation(s) on the levels of planning, implementation and reflection of cooperation seminars are elicited. The findings also have implications for the study regulations for the German teaching profession and have already been taken into account with initial changes.

Yet, compositional changes associated with shrub encroachment are often overlooked despite having important effects on ecosystem functioning. We document the compositional change and potential drivers for a northern Namibian Combretum woodland transitioning into a Terminalia shrubland. We use a multiproxy record (pollen, sedimentary ancient DNA, biomarkers, compound-specific carbon (delta C-13) and deuterium (delta D) isotopes, bulk carbon isotopes (delta(13)Corg), grain size, geochemical properties) from Lake Otjikoto at high taxonomical and temporal resolution. We provide evidence that state changes in semiarid environments may occur on a scale of one century and that transitions between stable states can span around 80 years and are characterized by a unique vegetation composition. We demonstrate that the current grass/woody ratio is exceptional for the last 170 years, as supported by n-alkane distributions and the delta C-13 and delta(13)Corg records. Comparing vegetation records to environmental proxy data and census data, we infer a complex network of global and local drivers of vegetation change. While our delta D record suggests physiological adaptations of woody species to higher atmospheric pCO(2) concentration and drought, our vegetation records reflect the impact of broad-scale logging for the mining industry, and the macrocharcoal record suggests a decrease in fire activity associated with the intensification of farming. Impact of selective grazing is reflected by changes in abundance and taxonomical composition of grasses and by an increase of nonpalatable and trampling-resistant taxa. In addition, grain-size and spore records suggest changes in the erodibility of soils because of reduced grass cover. Synthesis. We conclude that transitions to an encroached savanna state are supported by gradual environmental changes induced by management strategies, which affected the resilience of savanna ecosystems. In addition, feedback mechanisms that reflect the interplay between management legacies and climate change maintain the encroached state.

Although climate-based ENMs provide critical baseline information, the inclusion of non-climatic predictors related to vegetation cover might generate more realistic scenarios. This assumption is particularly relevant for species with life-history traits related to forest habitats and sensitive to habitat loss and fragmentation. Here, we developed ENMs for 36 Atlantic Forest endemic birds considering two sets of predictor variables: (i) climatic variables only and (ii) climatic variables combined with the percentage of remaining native vegetation. We hypothesized that the inclusion of native vegetation data would decrease the potential range distribution of forest-dependent species by limiting their occurrence in regions harboring small areas of native vegetation habitats, despite otherwise favorable climatic conditions. We also expected that habitat restriction in the climate-vegetation models would be more pronounced for highly forest-dependent birds. The inclusion of vegetation data in the modeling procedures restricted the final distribution ranges of 22 out of 36 modeled species, while the 14 remaining presented an expansion of their ranges. We observed that species with high and medium forest dependency showed higher restriction in range size predictions between predictor sets than species with low forest dependency, which showed no alteration or range expansion. Overall, our results suggest that ENMs based on climatic and landscape variables may be a useful tool for conservationists to better understand the dynamic of bird species distributions in threatened and highly fragmented regions such as the Atlantic Forest hotspot.(c) 2021 Associacao Brasileira de Cie circumflex accent ncia Ecol ogica e Conservacao.

This study aims to reconstruct changes in terrestrial vegetation composition and taxa richness during the glacial Late Pleistocene and the interglacial Holocene in the sparsely studied southeastern Yakutia (Siberia) by using pollen and sedimentary ancient DNA (sedaDNA) records. Pollen and sedaDNA metabarcoding data using the trnL g and h markers were obtained from a sediment core from Lake Bolshoe Toko. Both proxies were used to reconstruct the vegetation composition, while metabarcoding data were also used to investigate changes in plant taxa richness. The combination of pollen and sedaDNA approaches allows a robust estimation of regional and local past terrestrial vegetation composition around Bolshoe Toko during the last similar to 35,000 years. Both proxies suggest that during the Late Pleistocene, southeastern Siberia was covered by open steppe-tundra dominated by graminoids and forbs with patches of shrubs, confirming that steppe-tundra extended far south in Siberia. Both proxies show disturbance at the transition between the Late Pleistocene and the Holocene suggesting a period with scarce vegetation, changes in the hydrochemical conditions in the lake, and in sedimentation rates. Both proxies document drastic changes in vegetation composition in the early Holocene with an increased number of trees and shrubs and the appearance of new tree taxa in the lake's vicinity. The sedaDNA method suggests that the Late Pleistocene steppe-tundra vegetation supported a higher number of terrestrial plant taxa than the forested Holocene. This could be explained, for example, by the "keystone herbivore" hypothesis, which suggests that Late Pleistocene megaherbivores were able to maintain a high plant diversity. This is discussed in the light of the data with the broadly accepted species-area hypothesis as steppe-tundra covered such an extensive area during the Late Pleistocene.

T1 - Varieties of Supernatural Depictions BT - Classics in Contemporary Media JF - thersites 17 N2 - This article proposes several conceptual frameworks for examining the widespread use of classical intertexts depicting the supernatural in popular media. Whether the supernatural is viewed as reality or simply a trope, it represents the human capacity and desire to explore worlds and meanings beyond the obvious and mundane. Representations of classical gods, heroes, and monsters evoke the power of mythic stories to probe and explain human psychology, social concerns, philosophical questions, and religious beliefs, including belief about the paranormal and supernatural. The entertainment value of popular media allows creators and audiences to engage with larger issues in non-dogmatic and playful ways that help them negotiate tensions among various beliefs and identities. This paper also gives an overview of the other articles in this journal issue, showing overlapping themes and patterns that connect with these tensions. By combining knowledge of classical myths in their original contexts with knowledge about contemporary culture, classical scholars contribute unique perspectives about why classical intertexts dominate in popular media today.
