@article{65373, abstract = {{To reduce CO₂ emissions, the automotive industry is adopting multi-material structures. Fusion-based joining reaches its limits for aluminium–steel due to brittle intermetallic phases and mismatched thermophysical properties; therefore, mechanical joining (e.g., SPR) is used. Though conventional SPR requires tool changes for different stack-ups. Versatile self-piercing riveting (V-SPR) addresses this with an extended punch actuator and a multi-range-capable rivet (Kappe in PERD16:363–378, 2022), enabling joints up to 600 MPa across varying thicknesses without retooling. With the use of ultra-high-strength steels up to 1000 MPa, optimisation is required. This study quantifies how rivet shank geometry affects joint formation using a design of experiments and validated 2D axisymmetric FE simulations. The optimum depends strongly on the material system. For CP1000–EN AW-6014, maximum interlock f is predicted for a medium shank thickness of about 0.73 mm, a small internal foot radius of 0.620 mm, and a deeper drill depth of 3.136 mm, yielding f fc =0.4503 mm with a desirability of 0.954. For EN AW-6014–EN AW-6014, the optimum shifts to a thinner shank of 0.670 mm, a larger internal foot radius of 0.820 mm and a shallow drill depth of 2.30 mm, giving ffc = 0.3023 mm with a desirability of 1.0. A compromise geometry of 0.713 mm shank thickness, 0.776 mm internal foot radius and 2.755 mm drill depth achieves ffc = 0.3641 mm for CP1000–aluminium and ffc = 0.1851 mm for aluminium–aluminium with an overall desirability D = 0.6378, expanding V-SPR to ultra-high-strength steel–aluminium joints while maintaining aluminium joinability.}}, author = {{Kaimann, Pia Katharina and Ritter, Nico and Bobbert, Mathias and Meschut, Gerson}}, issn = {{2731-6564}}, journal = {{Discover Mechanical Engineering}}, number = {{1}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Influence of the shank geometry on the joint formation of the versatile self-piercing riveting of ultra-high-strength steel-aluminium and aluminium-aluminium assemblies}}}, doi = {{10.1007/s44245-026-00221-y}}, volume = {{5}}, year = {{2026}}, } @article{65375, abstract = {{Abstract Vitamin D has been associated with depression, potentially via anti-inflammatory mechanisms, yet data is scarce, particularly in adolescence. We investigated (1) whether lower vitamin D status is associated with greater depression severity and (2) whether this association is statistically moderated by inflammation in patients of a child and adolescent psychiatry department. At admission fasting morning venous blood was drawn. Serum vitamin D (25(OH)D) and C-reactive protein (CRP) were analyzed in all participants [n=465 (64.7%♀; 11.3-18.9 years)]. In a subsample [n=177], we additionally measured tumor necrosis factor-alpha, interferon-gamma and interleukin (IL)-1β, IL-6, IL-8, IL-10. Depression severity was assessed by the Beck Depression Inventory-II (BDI-II) [n=450], the Diagnostic System for Mental Disorders in Childhood and Adolescence via self-assessment (DISYPS Self) [n=441], and parent-assessment (DISYPS Proxy) [n=422]. Overall, 43.2% [n=201] were at risk for vitamin D deficiency (<30nmol/L), and 73.5%-83.2% –depending on assessment tool– showed at least mild depression. Linear regression revealed an inverse association between 25(OH)D and BDI-II in both crude and CRP-adjusted full-sample models. Logistic regressions showed a robust inverse association between 25(OH)D and DISYPS Proxy, but not for DISYPS Self. Although 25(OH)D was inversely correlated with some pro-inflammatory markers, neither their inclusion in regression models nor formal mediation analyses supported inflammation as a mediator of the vitamin D–depression association. Overall, our results suggest that vitamin D relates modestly to both depression and inflammation in adolescence.

But what does it do to us to be on the receiving end of such measurement? One of the world’s most successful global metrics is the school grade. Long predating the digital age, educational marks can be traced back at least to sixteenth-century European schools and have since conquered the world, becoming the indicator of academic achievement. To understand what it means to be quantified, Noëlle Rohde undertook in-depth fieldwork in a German comprehensive school where students receive more than one hundred grades per year. By staying close to the pupils as they are continually examined and assessed, her ethnography illustrates how marks mould students’ self-images, how they enforce meritocratic thinking and serve as a potent disciplinary tool.

The authors adapt a global survey instrument to the Indonesian context and collect responses from Indonesian tax officers and firms. Transfer pricing is perceived as the most complex tax regulation which is consistent with cross-country studies. However, in contrast to the global findings, statutory tax rates and taxes on dividends rank second and third in Indonesia. While Indonesian tax officers emphasize the complexity of transfer pricing regulations, firms are more concerned about the complexity of tax procedures, especially tax guidance and tax audits. Furthermore, comparative analyses show that tax officers perceive tax regulations as being more complex than tax procedures. In contrast, firms perceive the opposite, particularly for tax audits.

Students’ risk literacy is part of the interdisciplinary research project siMINT (Understanding complex STEM topics: Using simulations to promote competences for the 21st century). One first challenge in this project was to find a common ground for the inconsistently conceptualised terms of risk and risk literacy. Consequently, the aim of this paper is to contribute to the conceptualisation of risk and risk literacy. The first part of this paper provides a literature review on these areas, resulting in a working conceptualisation of the two concepts. We further carried out two consecutive steps of a Delphi study with N  = 15 and N  = 12 experts respectively, to develop a common conceptualisation based on the plurality of different dimensions and elements of risk and risk literacy. Based on the results of the first step of the Delphi study, we modified our working conceptualisation, using a common model of risk and risk literacy with different dimensions. In the second step of the Delphi study, the experts comment on (i) the dimensions and (ii) the elements of risk and risk literacy in these dimensions. The results showed that the experts are able to locate their individual definitions of risk in the model with three dimensions (relation between risk/uncertainty, connotation, and mathematical object) that we developed and to formulate reasons for their allocation. Furthermore, the results revealed that risk literacy consists of subsets of mathematical and non-mathematical elements that the experts rate differently with regard to their importance. In general, the results contribute to clarifying the constructs of risk and risk literacy as a basis for developing approaches to improve risk literacy. }}, author = {{Eichler, Andreas and Büchter, Theresa and Binder, Karin}}, issn = {{0173-5322}}, journal = {{Journal für Mathematik-Didaktik}}, number = {{1}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Conceptualising Risk and Risk Literacy—results of a Delphi Study Konzeptualisierung von Risiko und Risikokompetenz – Ergebnisse einer Delphi-Studie}}}, doi = {{10.1007/s13138-026-00268-0}}, volume = {{47}}, year = {{2026}}, } @inbook{64230, author = {{Zick, Andreas and Diekmann, Isabell}}, booktitle = {{The Sage Handbook of Psychological Perspectives on Diversity, Equity, and Inclusion}}, editor = {{Esses, Victoria M. and Dovidio, John F. and Jetten, Jolanda and Sekaquaptewa, Denise and West, Keon}}, isbn = {{9781529680836}}, publisher = {{SAGE Publications Ltd }}, title = {{{Anti-Muslim Racism: Facets, Roots, and Consequences}}}, year = {{2026}}, } @article{65374, author = {{Schlarbaum, Laura and Jankovic, Nicole and Bühlmeier, Judith and Hohoff, Eva and Dankers, Rhea and Engler, Harald and Hirtz, Raphael and Zwanziger, Denise and Grasemann, Corinna and Peters, Triinu and Hinney, Anke and Antel, Jochen and Föcker, Manuel and Libuda, Lars}}, issn = {{1436-6207}}, journal = {{European Journal of Nutrition}}, number = {{3}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Does inflammation moderate the effect of vitamin D supplementation on depressive symptoms?
