The Role of Religiosity on Mental Health Help-Seeking

The presentation covers the rationale, methodology, and results of a mixed-methods study designed to answer the following research question: What if any, is the role of religiosity and the impact on mental health among college students and their willingness to seek emotional/mental health support from a religious university? Data will be collected via a survey and individual in-depth interviews from a convenience sample of students at Southern Adventist University. Finally, it discusses implications for practice or policy change

Optimisation de bétons fibrés à ultra-hautes performances et caractérisation de leurs propriétés en contexte industriel

RÉSUMÉ Au cours des dernières décennies, d’importantes avancées technologiques dans le domaine du béton ont permis la mise au point de Bétons Fibrés à Ultra-hautes Performances (BFUP). Depuis les années 1980, l’amélioration des connaissances au sujet de ce matériau et la multiplication des projets de construction et de réhabilitation en faisant usage ont amorcé une démocratisation de son utilisation. Cependant, la création d’un BFUP s’avère encore être un processus long et coûteux. De plus, l’impact des températures de production et de cure différentes de celles considérées en laboratoire est encore méconnu sur les propriétés de ce matériau. Or, ces connaissances sont cruciales pour son utilisation plus étendue dans l’industrie de la construction.----------ABSTRACT Over the last decades, significant advances in concrete technology have resulted in the development of Ultra High Performances Fiber Reinforced Concretes (UHPFRC). Since 1980s, improvement in knowledge about this material and the increase of its use in construction and rehabilitation projects have begun to allow its democratization. However, developing a UHPFRC is still a long and costly process. In addition, the impact of mixing and curing temperatures different from those considered in laboratory on the properties of this material is still unknown. This knowledge is crucial for its wider use in the construction industry

Development and validation of a piloted simulation of a helicopter and external sling load

A generalized, real time, piloted, visual simulation of a single rotor helicopter, suspension system, and external load is described and validated for the full flight envelope of the U.S. Army CH-54 helicopter and cargo container as an example. The mathematical model described uses modified nonlinear classical rotor theory for both the main rotor and tail rotor, nonlinear fuselage aerodynamics, an elastic suspension system, nonlinear load aerodynamics, and a loadground contact model. The implementation of the mathematical model on a large digital computing system is described, and validation of the simulation is discussed. The mathematical model is validated by comparing measured flight data with simulated data, by comparing linearized system matrices, eigenvalues, and eigenvectors with manufacturers' data, and by the subjective comparison of handling characteristics by experienced pilots. A visual landing display system for use in simulation which generates the pilot's forward looking real world display was examined and a special head up, down looking load/landing zone display is described

Stereotype threat-effects for Turkish-origin migrants in Germany: Taking stock of cumulative research evidence

Source at https://doi.org/10.1177/1474904118807539.Turkish-origin migrants on average show lower academic performance than Germans. This achievement gap cannot be fully explained by socio-economic differences between the groups. Negative competence stereotypes about Turkish-origin students predict the causal attributions that German preservice teachers make for migrants’ academic underperformance. Specifically, the more strongly preservice teachers endorse negative competence stereotypes, the more likely they are to attribute academic underperformance of Turkish-origin migrants to the migrants themselves and less to the educational system. Stereotype threat theory posits that the activation of stereotypes in test situations can reduce the performance of members of the negatively stereotyped group. Based on this theory, we propose that negative stereotypes provide a social-psychological explanation for the academic underperformance of Turkish-origin migrants compared to Germans. A series of six experiments conducted within a research project funded by the German Ministry of Education and Research investigated stereotype threat effects for Turkish-origin migrants. Two new moderator variables were identified: implicit theory of intelligence and vertical collectivism. A meta-analysis of the six studies showed a small, non-significant mean effect for stereotype threat main effects, but a significant medium-sized mean effect for moderated stereotype threat effects. Limitations and practical implications of stereotype threat effects in educational settings are discussed
