Abstract: Aluminium metal matrix composites are promising materials for automotive brake discs, and it is critical to assess their wear performance in different braking conditions. This article presents the wear behaviour of aluminium-based composites with different Al-Si matrix alloys added with nickel and copper to retain mechanical strength at high temperatures. The wear tests were conducted at room and high temperatures (250 and 400 °C) to simulate different braking conditions on a pin-on-plate tribometer. The coefficient of friction is in the range of 0.15–0.17 for all materials at room temperature. The specific wear rates of the brake pad and the disc materials indicate that material transfer occurs from the brake pad to the metal counterpart. Microscopy investigations of the wear tracks confirm the material transfer on the composites. It protects the composite surface from wear damage and maintains a stable coefficient of friction. To translate these results into real-world scenarios, the findings of this study suggest that aluminium-based metal matrix composite brake discs have a longer product lifespan compared to the grey cast iron brake discs; the brake pads for the composites would be the components to need replacement due to wear during the product life instead of the brake discs.

De verschillende invalshoeken van internationale financieel-economische criminaliteit
In dit nummer staat het thema internationale financieel-economische criminaliteit centraal. Grensoverschrijdende financieel-economische criminaliteit is vrijwel altijd georganiseerde criminaliteit, maar is veelal ook verweven met andere vormen van zware georganiseerde en ondermijnende misdaad. Omgekeerd geldt dat georganiseerde criminaliteit grotendeels winstgedreven is en bijna altijd grensoverschrijdende kernmerken heeft. Het is dan ook een logisch gevolg dat Europese wet- en regelgeving daarop anticipeert, zich verder ontwikkelt en uitbreidt. De bijdragen van dit nummer belichten het thema vanuit verschillende invalshoeken.

Published: February 2025

As formações de quilombos no Brasil datam do século XVI, e surgiram como forma de resistência às condições de vida e trabalho impostas no período colonial e imperial. No presente, a visibilidade dessas comunidades fez com que o conceito de quilombo fosse modificado, buscando cobrir os diferentes contextos de posse de terras por populações predominantemente negras no país. A pesquisa teve como objetivo principal demarcar a existência dessas formas de luta, busca por direitos e os desafios da auto-organização quilombola. Foi utilizada uma abordagem qualitativa, com levantamento de documentos e bibliografias sobre os debates com referências estaduais do movimento quilombola e seus espaços formativos, com foco no documento “Mapeamento estadual das comunidades Quilombolas do Ceará”, lançado em maio de 2019. Há muitos desafios pela frente quando se fala em conquista de direitos, e, sobretudo, a manutenção dos territórios, já que a titularização é um processo longo e cheio de empreitadas.
Impact of a multimodal intervention on junior and senior hospital physicians’ job satisfaction and wellbeing: a matched pre- and post-intervention study
Authors: Levy Monica , Donzé Jacques , Zender Hervé , John Gregor 
Published: February 2025

BACKGROUND: Physician wellbeing has a direct impact on patient care. Meta-analyses have concluded that interventions are moderately effective at reducing physician burnout, but new studies are needed to target populations at higher risk (e.g. young physicians) and determine which interventions might be most effective.
METHOD: Using matched questionnaires, we conducted a cross-sectional pre-post study of a multimodal intervention to promote physician wellbeing. The intervention involved a change in institutional culture, information on occupational wellbeing, and the organisation of undisturbed lunch breaks and short breaks during the day. The primary outcome was the proportion of physicians satisfied with their job (scoring >3 points on the Work-Related Quality of Life [WRQoL] scale). Secondary outcomes were overall WRQoL score, WRQoL subscale scores, number of short breaks taken during the working day, number of lunch breaks taken, physicians’ likeliness of recommending their job to peers, monthly overtime hours worked and monthly sick days. Subgroup analyses included women vs men, residents vs chief residents/senior physicians, and participants with vs without children. We also explored potential factors influencing WRQoL in the pre-intervention population.
RESULTS: Pre- and post-intervention questionnaires were returned by 134 (63%) and 87 (42%) physicians, respectively, with 75 responding to both (matched). The intervention significantly increased the proportion of physicians satisfied with their job (from 49/75 [65%] to 58/75 [77%], p = 0.02), median overall WRQoL score (from 3.3 [IQR: 2.8–3.8] to 3.5 [IQR: 3.1–3.8], p <0.01), median Home-Work Interface subscale score (from 2.7 [IQR: 2.0–3.3] to 3.0 [IQR: 2.3–3.7], p = 0.01) and median General Well-Being subscale score (from 3.4 [IQR: 2.6–4.0] to 3.6 [IQR: 3.0–4.0], p <0.01). Residents showed a greater increase in overall WRQoL median score (from 3.2 [IQR: 2.7–3.6] to 3.5 [IQR: 3.3–3.8]) than chief residents/senior physicians (3.3 [IQR: 2.9–3.9] to 3.4 [IQR: 3.0–3.8], p <0.01 for group difference). No significant differences were seen in other subgroups or secondary outcomes in the matched population. Among the 134 participants in the pre-intervention period, those taking a daily lunch break, sleeping 7 hours or more or self-reporting doing sports activities on weekdays had higher overall WRQoL scores.
CONCLUSIONS: This wellbeing intervention increased physicians’ WRQoL scores. However, the difference was small and its relevance remains uncertain.

Using a Deconstruction and Reconstruction Approach in a First-Year Seminar Course
Authors: Quinn Michael A 
Published: February 2025

Aim: First Year Seminars (FYS) are a high-impact practice for student success. FYS seminars can offer both personal development and academic goals. Incorporating research papers and presentations into FYS can be challenging to teach but can provide value to students not receiving these skills in other first-semester courses. The goal of this paper was to lay out the details of a deconstruction and reconstruction strategy for teaching research skills in an FYS course.
Methods: In the deconstruction and reconstruction approach, students take apart research papers into parts to gain a deeper understanding of how research works. The parts of the research paper are then put back together with the student writing a paper and doing a class presentation. Detail is provided into how to implement this strategy in a classroom, including information on assignment language.
Results: This new approach was successful when piloted in a section of the FYS course. Student performance on the deliverables in the course was high. And post-course surveys of students showed positive impacts of their FYS skills on future courses.
Conclusion: This strategy focuses on skills in research, PowerPoint, and public speaking. At the end of the course, the students' presentation skills had improved. A deconstruction and reconstruction approach were found to be feasible and potentially valuable. This represents a new approach to teaching research skills in FYS courses.

This study uses a type of qualitative research with a descriptive approach. The data sources used are primary and secondary data. The technique for determining informants in this study uses purposive sampling. This study uses the theory of measuring the performance of public organizations according to Agus Dwiyanto (2017). The results of the study show that the performance of the Goods and Services Procurement Unit in improving e-government through the local MSME e-catalog in Badung Regency is quite good, which in productivity indicators is not optimal, there is a need for optimization of the number of human resources and cooperation. Service quality indicators are not optimal because there is still a lack of technical guidance provided to providers. The responsiveness indicator can be said to be optimal. Responsibility indicators can be said to be optimal. Accountability indicators can be said to be quite optimal. Therefore, the author recommends providing technical guidance to providers, collaborating with various parties, optimizing existing human resources through training and improving employee skills, and continuing to monitor and evaluate periodically.
