An ecological approach to psychological adjustment: A field survey among refugees in Germany

The situation of refugees in Germany and other countries is a current and important matter. The present study adopts an ecological approach to investigate how refugees perceive the welcoming climate in Germany and the consequences of this perception. To further explore the refugees’ situation, we examined several predictors of their psychological adjustment and acculturation attitudes. In a field study in Eastern Germany with N= 94 refugees as participants, we assessed the perceived context of reception, and perceived acculturation attitudes as contextual variables, discrimination and contact as intergroup variables and, on the individual level, psychological adjustment as well as the personal acculturation attitudes as dependent variables. The results revealed that more perceived discrimination resulted in an increase in reported psychological problems. Refugees living in asylum centers reported more psychological problems and more perceived discrimination than those living in independent housing. The perceived context of reception positively predicted refugees’ desire for maintenance of intergroup relations with the host society. Positive intergroup contact lowered their desire for cultural maintenance. In sum, this study gives us rare and valuable insight into refugees’ perspectives in the context of recent immigration to Germany. In doing so, it emphasizes the importance of a welcoming climate. The study shows how meaningful the assessment of the perceived context of reception is. Practical implications for fields such as the accommodation of refugees are discussed.     

Cultural similarity and adjustment of expatriate academics

The findings of a number of recent empirical studies of business expatriates, using different samples and methodologies, seem to support the counter-intuitive proposition that cultural similarity may be as difficult to adjust to as cultural dissimilarity. However, it is not obvious that these results also are applicable to other groups of expatriates. To explore this eventuality, an electronic survey was directed towards expatriate academics in 34 universities in five European countries. For the purpose of this study, they were sorted into two groups, expatriate academics from EU countries and non-EU countries. Results showed that although the perceived cultural similarity between host and home country for the two groups of investigated respondents was different, there was neither any difference in their adjustment nor in the time it took for them to become proficient. Implications of these findings are discussed.     

Influence of stick stiffness and puck weight on puck velocity during slap shots in women’s ice hockey

Previous studies have found that reduced stick stiffness increases puck velocity in young male ice hockey players. This study investigates the hypothesis that female players are disadvantaged by using equipment that is designed for taller and stronger players. The purpose of this study was to investigate if stick flexibility and puck weight affect puck velocity in standing slap shots performed by female ice hockey players. There was a significant increase in puck velocity (4.1%, p = 0.037) when stick stiffness and puck weight were reduced. ANOVA revealed that there was a significant correlation between stick, puck and the participant herself (R ² = 0.987). Spearman’s correlation analysis revealed that participants with higher puck velocities benefitted the most when the stick flexibility and puck weight were reduced (r = 0.648, p = 0.043). It was concluded that decreased stick stiffness and puck weight increased puck velocity in standing slap shots for female ice hockey players.
