The Nature and Prevention of Political Violence.}, pages = {1}, abstract = {Research on the development of bullying is often based upon Bronfenbrenner's socioecological model (Swearer \& Hymel, 2015). Thus, various relevant contextual variables have been identified, including classroom climate and school climate (Thornberg et al., 2018; Zych et al., 2019). School climate has been defined in different ways, mostly including relationships between people in the school environment (Wang et al., 2016). Empirically, only the relationships between students (also summarised within the class as classroom climate) and between teachers and pupils are usually considered. However, teachers have been identified as particularly significant in the bullying process and as role models for students (Colpin et al., 2021). Because of this, it is assumed that relationships among teachers can also be significant risk factors for student bullying. In this study, we investigate communication climate among teachers as part of the school climate and its associations to student bullying. In addition, we follow Bronfenbrenner's idea of interactions among contextual levels by considering both school climate and classroom climate and investigating moderation effects. Data was collected from more than 550 teachers and 2,000 students in 114 classes at 24 schools in Germany. The analyses involved three-level hierarchical binary regression analyses and cross-level interaction models. Findings suggest that staff communication climate is not associated directly with students' experiences with bullying, but that the worse staff communication climate, the more students bully others in classrooms with high rates of rivalry (cross-level moderation). The associations will further be analysed under consideration of relevant control variables. Final results will be presented at the conference. The study broadens the contextual perspective on bullying by including more than one level at once and supports the importance of a whole-school perspective on bullying.}, language = {en} } @misc{BilzKansokDuscheFischeretal., author = {Bilz, Ludwig and Kansok-Dusche, Julia and Fischer, Saskia M. and Bartholom{\"a}us, Peter}, title = {What works in hate speech intervention and prevention in schools?

Derogatory expressions against certain groups of people are not a new phenomenon. However, hate speech has become much more widespread in recent years. After the Internet, the school is a place where hate speech occurs and where children and young people perpetrate, witness, and become victims of hate speech (Castellanos et al., 2023; Kansok-Dusche et al., 2023). Schools represent a suitable location to address hate speech incidents and to prevent future hate speech. To date, there is limited evidence on the availability, quality, and effectiveness of school-based anti-hate speech programs. The objective of this systematic review is to compile a catalogue of available anti-hate speech programs, that are particularly aimed at children and youth and that can be used to deal with hate speech in schools. Furthermore, their quality and utility are to be evaluated on a criteria-driven basis by two independent reviewers. The presentation will provide an overview of the 27 programmes identified and the initial results regarding their quality. Recommendations are given for the implementation of these programmes in schools and for their further improvement.}, language = {en} } @misc{FischerMacaulayBaraldsnesetal., author = {Fischer, Saskia M. and Macaulay, Peter J.

As part of a measurement campaign, the operation of a stack system is investigated, particularly under the operating conditions of a recuperated micro gas turbine. Above all, the performance and effectiveness of selected stack types at various operating pressures and operating temperatures are measured. With the test facility set up for such investigations, cell systems could be examined under atmospheric conditions and with pressures of up to 5 bar. It is shown that in operating conditions under pressure, the output of the fuel cell systems are improving. From a gauge pressure of 4 bar, the performance curve is flattened and higher pressures only produced a marginal increase in performance. Furthermore, the cells tested at overpressure show a steady-state behavior more quickly under load change requirements than in atmospheric operation. This means that more flexible operating modes with faster response behavior can be realized. By choosing a suitable operating temperature, the efficiency of the system is further increasing. Care was taken to select the operating conditions of the cell systems so that coking can be prevented. Finally, a statement can be made about the pressure dependence of the fuel conversion rate. Parasitic reactions at the anode can be related to the power output. The tests carried out have shown that the high-temperature fuel cell is a promising service provider of the future. A combination of SOFC high-temperature fuel cells and micro gas turbines in one machine could, in addition to the internal provision of the required pressure, also lead to better dynamics of the entire system and increase the energy yield from the primary energy source.}, language = {en} }
