Historians have similarly cast the kinds of Judaism Americans created as both unique to America and uniquely American. These characterizations are accurate to an extent. But to what extent did Jewish innovations in the United States take place in conversation with European Jewish developments?

No longer living in the places of their childhood, they settled in urban centers, such as in New York's Lower East Side. In this neighborhood, Galician Jews began to search for new relationships that linked the places they left and the ones where they arrived and settled. By looking at Galicia through the lens of autobiographical writings by former Jewish immigrants who became established residents of New York, this article emphasizes the role of regionalism in the context of transnational conceptions of a new American Jewish self-understanding. It argues that the key to analyzing the evolution of "eastern Europe" as a common place of origin for American Jewry is the constant dialogue between the places of origin and arrival. Specifically, philanthropic efforts during and after the First World War and the proliferation of tourism both enabled these settled immigrants to gradually replace regional notions, such as the idea of Galicia, with a mythical image of eastern Europe to create a sense of community as American Jews.}, language = {en} } @article{Cooperman2021, author = {Cooperman, Jessica}, title = {Jewish-Christian Dialogue and American Visions of the Postwar World}, series = {PaRDeS : Journal of the Association for Jewish Studies in Germany}, journal = {PaRDeS : Journal of the Association for Jewish Studies in Germany}, number = {27}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-520-0}, issn = {1614-6492}, doi = {10.25932/publishup-53748}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-537488}, pages = {117 -- 131}, year = {2021}, abstract = {American occupying forces made the promotion of Jewish-Christian dialogue part of their plans for postwar German reconstruction.

However, the many complexities involved in the differential expression and flexibility of these strategies are rarely fully understood. Therefore, for the first time, using a three-part cross-disciplinary laboratory experimental analysis, we investigated the diversity and plasticity of photoresponsive traits employed by one family of environmentally contrasting, ecologically important phytoflagellates. The results demonstrated an extensive inter-species phenotypic diversity of behavioural, physiological, and compositional photoresponse across the Chlamydomonadaceae, and a multifaceted intra-species phenotypic plasticity, involving a broad range of beneficial photoacclimation strategies, often attributable to environmental predisposition and phylogenetic differentiation. Deceptively diverse and sophisticated strong (population and individual cell) behavioural photoresponses were observed, with divergence from a general preference for low light (and flexibility) dictated by intra-familial differences in typical habitat (salinity and trophy) and phylogeny. Notably, contrasting lower, narrow, and flexible compared with higher, broad, and stable preferences were observed in freshwater vs. brackish and marine species. Complex diversity and plasticity in physiological and compositional photoresponses were also discovered. Metabolic characteristics (such as growth rates, respiratory costs and photosynthetic capacity, efficiency, compensation and saturation points) varied elaborately with species, typical habitat (often varying more in eutrophic species, such as Chlamydomonas reinhardtii), and culture irradiance (adjusting to optimise energy acquisition and suggesting some propensity for low light). Considerable variations in intracellular pigment and biochemical composition were also recorded. Photosynthetic and accessory pigments (such as chlorophyll a, xanthophyll-cycle components, chlorophyll a:b and chlorophyll a:carotenoid ratios, fatty acid content and saturation ratios) varied with phylogeny and typical habitat (to attune photosystem ratios in different trophic conditions and to optimise shade adaptation, photoprotection, and thylakoid architecture, particularly in freshwater environments), and changed with irradiance (as reaction and harvesting centres adjusted to modulate absorption and quantum yield). The complex, concomitant nature of the results also advocated an integrative approach in future investigations. Overall, these nuanced, diverse, and flexible photoresponsive traits will greatly contribute to the functional ecology of these organisms, addressing environmental heterogeneity and potentially shaping individual fitness, spatial and temporal distribution, prevalence, and ecosystem dynamics.}, language = {en} } @article{GallasRuerup2021, author = {Gallas, Elisabeth and R{\"u}rup, Miriam}, title = {"Advocate of the Jewish People"}, series = {PaRDeS : Journal of the Association for Jewish Studies in Germany}, journal = {PaRDeS : Journal of the Association for Jewish Studies in Germany}, number = {27}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-520-0}, issn = {1614-6492}, doi = {10.25932/publishup-53750}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-537501}, pages = {135 -- 142}, year = {2021}, language = {en} } @article{SchefflerNguyenHermanussen2021, author = {Scheffler, Christiane and Nguyen, Thi Hong and Hermanussen, Michael}, title = {Vietnamese migrants are as tall as they want to be}, series = {Human biology and public health}, journal = {Human biology and public health}, number = {2}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {2748-9957}, doi = {10.52905/hbph.v2.12}, year = {2021}, abstract = {Background: Members of the same social group tent to have the same body height.

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).

Diabetic neuropathy (DN) is associated with damage to nerve glial cells, their axons, and endothelial cells leading to impaired function and mobility. Objective: We aimed to examine the effects of an endurance-dominated exercise program on maximum oxygen consumption (VO2max), ground reaction forces, and muscle activities during walking in patients with moderate DN. Methods: Sixty male and female individuals aged 45-65 years with DN were randomly assigned to an intervention (IG, n = 30) or a waiting control (CON, n = 30) group. The research protocol of this study was registered with the Local Clinical Trial Organization (IRCT20200201046326N1). IG conducted an endurance-dominated exercise program including exercises on a bike ergometer and gait therapy. The progressive intervention program lasted 12 weeks with three sessions per week, each 40-55 min. CON received the same treatment as IG after the post-tests. Pre- and post-training, VO2max was tested during a graded exercise test using spiroergometry. In addition, ground reaction forces and lower limbs muscle activities were recorded while walking at a constant speed of ∼1 m/s. Results: No statistically significant baseline between group differences was observed for all analyzed variables. Significant group-by-time interactions were found for VO2max (p < 0.001; d = 1.22). The post-hoc test revealed a significant increase in IG (p < 0.001; d = 1.88) but not CON. Significant group-by-time interactions were observed for peak lateral and vertical ground reaction forces during heel contact and peak vertical ground reaction force during push-off (p = 0.001-0.037; d = 0.56-1.53). For IG, post-hoc analyses showed decreases in peak lateral (p < 0.001; d = 1.33) and vertical (p = 0.004; d = 0.55) ground reaction forces during heel contact and increases in peak vertical ground reaction force during push-off (p < 0.001; d = 0.92). In terms of muscle activity, significant group-by-time interactions were found for vastus lateralis and gluteus medius during the loading phase and for vastus medialis during the mid-stance phase, and gastrocnemius medialis during the push-off phase (p = 0.001-0.044; d = 0.54-0.81). Post-hoc tests indicated significant intervention-related increases in vastus lateralis (p = 0.001; d = 1.08) and gluteus medius (p = 0.008; d = 0.67) during the loading phase and vastus medialis activity during mid-stance (p = 0.001; d = 0.86). In addition, post-hoc tests showed decreases in gastrocnemius medialis during the push-off phase in IG only (p < 0.001; d = 1.28). Conclusions: This study demonstrated that an endurance-dominated exercise program has the potential to improve VO2max and diabetes-related abnormal gait in patients with DN. The observed decreases in peak vertical ground reaction force during the heel contact of walking could be due to increased vastus lateralis and gluteus medius activities during the loading phase.

Materials and Methods: Thirty elite male youth soccer players aged 10-17 years from the Tunisian first division participated in this study. The players were divided into pre- (G1, n = 15) and post-PHV (G2, n = 15) groups. Both groups completed a similar 6-week training program with two sessions per week of four CoD exercises. All players completed the following tests before and after intervention: CS-YBT; 5 JT; 10, 30, and 15 m-CoD; and 15 m-CoD + B, and data were analyzed using ANCOVA. Results: All 30 players completed the study according to the study design and methodology. Adherence rate was 100\% across all groups, and no training or test-related injuries were reported. Pre-PHV and post-PHV groups showed significant amelioration post-intervention for all dependent variables (after test > before test; p < 0.01, d = 0.09-1.51).

Methods: Semi-elite young kayakers and canoeists (N = 40, 13 ± 0.8 years, 11 girls) performed either MILV (70-80\% 1-RM, 6-12 repetitions per set) or LIHV (30-40\% 1-RM, 60-120 repetitions per set) strength training for one season. Linear mixed-effects models were used to compare effects of training condition on changes over time in 250 and 2,000 m time trials, handgrip strength, underhand shot throw, average bench pull power over 2 min, and skeletal muscle mass. Both between- and within-subject designs were used for analysis. An alpha of 0.05 was used to determine statistical significance. Results: Between- and within-subject analyses showed that monthly changes were greater in LIHV vs. MILV for the 2,000 m time trial (between: 9.16 s, SE = 2.70, p < 0.01; within: 2,000 m: 13.90 s, SE = 5.02, p = 0.01) and bench pull average power (between: 0.021 W⋅kg-1, SE = 0.008, p = 0.02; within: 0.010 W⋅kg-1, SE = 0.009, p > 0.05).

The AF of 10 subjects was examined manually by experienced testers while smelling at sniffing sticks with neutral, pleasant or disgusting odours.

The results show, inter alia, a significantly lower maximal isometric AF and a significantly higher AF at the onset of oscillations by perceiving disgusting odours compared to pleasant or neutral odours (p < 0.001). The adaptive holding capacity seems to reflect the functionality of the neuromuscular control, which can be impaired by disgusting olfactory inputs.

Exercising PLWH were less likely to report a heart arrhythmia for every increase in exercise duration (PR: 0.20: 95\% CI: 0.10-0.62, p < 0.01) and diabetes mellitus for every increase in exercise session per week (PR: 0.40: 95\% CI: 0.10-1, p < 0.01). Exercise frequency and duration are associated with a decreased risk of reporting arrhythmia and diabetes mellitus in PLWH.

The implementation of prevention programs requires early detection of individuals at risk. However, access to health care providers is limited in structurally weak regions. Brandenburg, a rural federal state in Germany, has an especially high MetS prevalence and disease burden. This study aims to validate and test the feasibility of a setup for mobile diagnostics of MetS and its secondary diseases, to evaluate the MetS prevalence and its association with moderating factors in Brandenburg and to identify new ways of early prevention, while establishing a "Mobile Brandenburg Cohort" to reveal new causes and risk factors for MetS. Methods In a pilot study, setups for mobile diagnostics of MetS and secondary diseases will be developed and validated. A van will be equipped as an examination room using point-of-care blood analyzers and by mobilizing standard methods. In study part A, these mobile diagnostic units will be placed at different locations in Brandenburg to locally recruit 5000 participants aged 40-70 years. They will be examined for MetS and advice on nutrition and physical activity will be provided. Questionnaires will be used to evaluate sociodemographics, stress perception, and physical activity. In study part B, participants with MetS, but without known secondary diseases, will receive a detailed mobile medical examination, including MetS diagnostics, medical history, clinical examinations, and instrumental diagnostics for internal, cardiovascular, musculoskeletal, and cognitive disorders. Participants will receive advice on nutrition and an exercise program will be demonstrated on site. People unable to participate in these mobile examinations will be interviewed by telephone. If necessary, participants will be referred to general practitioners for further diagnosis. Discussion The mobile diagnostics approach enables early detection of individuals at risk, and their targeted referral to local health care providers. Evaluation of the MetS prevalence, its relation to risk-increasing factors, and the "Mobile Brandenburg Cohort" create a unique database for further longitudinal studies on the implementation of home-based prevention programs to reduce mortality, especially in rural regions.

Problem solving can be defined as the search for possible changes in one's mind (Kahneman, 2003). In a recent study, Adams et al. (2021) assessed whether the predominant problem solving strategy when making changes involves adding or subtracting elements. In order to do this, they used several examples of simple problems, such as editing text or making visual patterns symmetrical, either in naturalistic settings or on-line. The essence of the authors' findings is a strong preference to add rather than subtract elements across a diverse range of problems, including the stabilizing of artifacts, creating symmetrical patterns, or editing texts. More specifically, they succeeded in demonstrating that "participants were less likely to identify advantageous subtractive changes when the task did not (vs. did) cue them to consider subtraction, when they had only one opportunity (vs. several) to recognize the shortcomings of an additive search strategy or when they were under a higher (vs. lower) cognitive load" (Adams et al., 2021, p. 258). Addition and subtraction are generally defined as de-contextualized mathematical operations using abstract symbols (Russell, 1903/1938). Nevertheless, understanding of both symbols and operations is informed by everyday activities, such as making or breaking objects (Lakoff and N{\´u}{\~n}ez, 2000; Fischer and Shaki, 2018). The universal attribution of "addition bias" or "subtraction neglect" to problem solving activities is perhaps a convenient shorthand but it overlooks influential framing effects beyond those already acknowledged in the report and the accompanying commentary (Meyvis and Yoon, 2021). Most importantly, while Adams et al.'s study addresses an important issue, their very method of verbally instructing participants, together with lack of control over several known biases, might render their findings less than conclusive. Below, we discuss our concerns that emerged from the identified biases, namely those regarding the instructions and the experimental materials.

Thus, microbes degrading these polymers significantly influence global carbon cycling and greenhouse gas production. Fungi are recognized as important for cellulose decomposition in terrestrial environments, but are far less studied in marine environments, where bacterial organic matter degradation pathways tend to receive more attention. In this study, we investigated the potential of fungi to degrade kelp detritus, which is a major source of cellulose in marine systems. Given that kelp detritus can be transported considerable distances in the marine environment, we were specifically interested in the capability of endophytic fungi, which are transported with detritus, to ultimately contribute to kelp detritus degradation. We isolated 10 species and two strains of endophytic fungi from the kelp Ecklonia radiata. We then used a dye decolorization assay to assess their ability to degrade organic polymers (lignin, cellulose, and hemicellulose) under both oxic and anoxic conditions and compared their degradation ability with common terrestrial fungi. Under oxic conditions, there was evidence that Ascomycota isolates produced cellulose-degrading extracellular enzymes (associated with manganese peroxidase and sulfur-containing lignin peroxidase), while Mucoromycota isolates appeared to produce both lignin and cellulose-degrading extracellular enzymes, and all Basidiomycota isolates produced lignin-degrading enzymes (associated with laccase and lignin peroxidase). Under anoxic conditions, only three kelp endophytes degraded cellulose. We concluded that kelp fungal endophytes can contribute to cellulose degradation in both oxic and anoxic environments. Thus, endophytic kelp fungi may play a significant role in marine carbon cycling via polymeric organic matter degradation.}, language = {en} } @article{KuehneFauthAyBrysonetal.2021, author = {K{\"u}hne, Franziska and Fauth, Henriette and Ay-Bryson, Destina Sevde and Visser, Leonie N.C. and Weck, Florian}, title = {Communicating the diagnosis of cancer or depression}, series = {Cancer medicine}, volume = {10}, journal = {Cancer medicine}, number = {24}, publisher = {Wiley}, address = {Hoboken, New Jersey, USA}, issn = {2045-7634}, doi = {10.1002/cam4.4396}, pages = {9012 -- 9021}, year = {2021}, abstract = {Background Communicating a diagnosis is highly important, yet complex, especially in the context of cancer and mental disorders. The aim was to explore the communication style of an oncologist vs. psychotherapist in an online study. Methods Patients (N = 136: 65 cancer, 71 depression) were randomly assigned to watch a standardized video vignette with one of two communication styles (empathic vs. unempathic). Outcome measures of affectivity, information recall, communication skills, empathy and trust were applied. Results Regardless of diagnosis, empathic communication was associated with the perception of a significantly more empathic (p < 0.001, η2partial = 0.08) and trustworthy practitioner (p = 0.014, η2partial = 0.04) with better communication skills (p = 0.013, η2partial = 0.05). Cancer patients reported a larger decrease in positive affect (p < 0.001, η2partial = 0.15) and a larger increase in negative affect (p < 0.001, η2partial = 0.14) from pre- to post-video than depressive patients.

Akan has two types of wh-question structures (wh-in-situ and wh-ex-situ questions), which allows an investigation of children's acquisition of these two question structures and their preferences for one or the other. Our results show that adults prefer to use wh-ex-situ questions over wh-in-situ questions. The results from the children show that both age groups have the two question structures in their linguistic repertoire. However, they differ in their preferences in usage in the elicited production task: while the 5-year-olds preferred the wh-in-situ structure over the wh-ex-situ structure, the 4-year-olds showed a selective preference for the wh-in-situ structure in who-questions. These findings suggest a developmental change in wh-question preferences in Akan-learning children between 4 and 5 years of age with a so far unobserved u-shaped developmental pattern. In the elicited imitation task, all groups showed a strong tendency to maintain the structure of in-situ and ex-situ questions in repeating grammatical questions. When repairing ungrammatical ex-situ questions, structural changes to grammatical in-situ questions were hardly observed but the insertion of missing morphemes while keeping the ex-situ structure.

However, contradictory observations have been made regarding whether short period events are faithfully preserved in stratigraphic archives; for instance, in marine sediments offshore large river systems. On the one hand, short period events are hypothesized to be non-detectable in the signature of terrestrially derived sediments due to buffering during sediment transport along large river systems. On the other hand, several studies have detected signals of short period events in marine records offshore large river systems. We propose that this apparent discrepancy is related to the lack of a differentiation between different types of signals and the lack of distinction between river response times and signal propagation times. In this review, we (1) expand the definition of the term 'signal' and group signals in sub-categories related to hydraulic grain size characteristics, (2) clarify the different types of 'times' and suggest a precise and consistent terminology for future use, and (3) compile and discuss factors influencing the times of signal transfer along sediment routing systems and how those times vary with hydraulic grain size characteristics.

Im vorliegenden Beitrag werden Befunde eines Forschungsprojekts speziell zur Studieneingangsphase sowie erg{\"a}nzend zur Studienmitte vorgestellt, dessen Ziel es war, Bedingungen eines erfolgreichen Studieneinstiegs zu identifizieren und Empfehlungen f{\"u}r eine Optimierung des Studieneingangs abzuleiten. Das Forschungsdesign umfasste neben qualitativen Studien vor allem eine quantitative L{\"a}ngsschnittbefragung an f{\"u}nf Universit{\"a}ten (Potsdam, Mainz, Magdeburg, Kiel und Greifswald). Im Ergebnis der Analysen konnte die forschungsleitende Hypothese, dass Maßnahmen zum Studieneingang vor allem dann zur Erh{\"o}hung des Studienerfolgs einen Beitrag leisten, wenn sie zur akademischen und sozialen Integration in die Hochschule beitragen, best{\"a}tigt werden. Bedeutsam f{\"u}r den Studienerfolg sind demnach insbesondere solche Faktoren wie die Identifikation mit dem Studienfach, die Selbstwirksamkeit, die berufliche bzw. erfolgsorientierte Lernmotivation und die akademische Integration. Daneben konnte ein positiver Einfluss des sozialen Klimas sowie des Forschungs- und Praxisbezugs auf die Studienzufriedenheit nachgewiesen werden. Weiterf{\"u}hrende Analysen zur Studienmitte verdeutlichen zudem, dass f{\"u}r die beiden Studienphasen (Eingang und Studienmitte) gleiche Faktoren bei zum Teil unterschiedlicher Gewichtung eine Rolle spielen. So ist die soziale Integration ein wesentlicher Pr{\"a}diktor in beiden Phasen - in der Eingangsphase eher in die Studierendenschaft und im weiteren Studienverlauf (Studienmitte) eher in die akademische Gemeinschaft (in Form von Lehrenden). Insofern muss die Eingangsfrage wie folgt beantwortet werden: Ja, alles auf Anfang, aber dann mit den Bem{\"u}hungen, soziale und akademische Integration aller Studierenden voll und ganz zu gew{\"a}hrleisten. Zudem machen die Befunde auf die bisher offenbar untersch{\"a}tzte Rolle von Verwertungsmotiven aufmerksam.}, language = {de} } @article{Lehr2020, author = {Lehr, Moritz}, title = {Mass Effect}, series = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, journal = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-489-0}, doi = {10.25932/publishup-48576}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-485761}, pages = {259 -- 282}, year = {2020}, language = {de} } @article{West2020, author = {West, Thomas}, title = {Grand Theft Auto V}, series = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, journal = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-489-0}, doi = {10.25932/publishup-48572}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-485723}, pages = {195 -- 217}, year = {2020}, language = {de} } @article{Meier2020, author = {Meier, Jan-Niklas}, title = {Wolfenstein: The New Order}, series = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, journal = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-489-0}, doi = {10.25932/publishup-48589}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-485899}, pages = {401 -- 420}, year = {2020}, language = {de} } @article{Wendorf2020, author = {Wendorf, Daniel}, title = {Silent Hill 2}, series = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, journal = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-489-0}, doi = {10.25932/publishup-48583}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-485833}, pages = {321 -- 341}, year = {2020}, language = {de} } @article{Meijer2020, author = {Meijer, Saskia}, title = {Brothers: A Tale of Two Sons}, series = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, journal = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-489-0}, doi = {10.25932/publishup-48566}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-485664}, pages = {107 -- 124}, year = {2020}, language = {de} } @article{Gottschalk2020, author = {Gottschalk, Matthias}, title = {Company of Heroes und Company of Heroes 2}, series = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, journal = {„Wir alle treffen Entscheidungen im Leben, aber letztendlich treffen unsere Entscheidungen uns." : didaktische Potenziale digitaler Spielwelten}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-489-0}, doi = {10.25932/publishup-48568}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-485680}, pages = {143 -- 158}, year = {2020}, language = {de} } @article{Stegemann2020, author = {Stegemann, Tim}, title = {F{\"o}deraler Flickenteppich - Die Umsetzung von Kinderrechten in den deutschen Bundesl{\"a}ndern im Vergleich}, series = {MenschenRechtsMagazin : MRM ;

These adolescents sometimes use aggression to defend or promote their status. The aim of this study was to examine the relationships among social status insecurity, callous-unemotional (CU) traits, and popularity-motivated aggression and prosocial behaviors among adolescents, while controlling for gender. Another purpose was to examine the potential moderating role of CU traits in these relationships. Participants were 1,047 (49.2\% girls; Mage = 12.44 years; age range from 11 to 14 years) in the 7th or 8th grades from a large Midwestern city. They completed questionnaires on social status insecurity, CU traits, and popularity-motivated relational aggression, physical aggression, cyberaggression, and prosocial behaviors. A structural regression model was conducted, with gender as a covariate. The model had adequate fit. Social status insecurity was associated positively with callousness, unemotional, and popularity-motivated aggression and related negatively to popularity-motivated prosocial behaviors. High social status insecurity was related to greater popularity-motivated aggression when adolescents had high callousness traits. The findings have implications for understanding the individual characteristics associated with social status insecurity.}, language = {en} }
