Relations between adolescents' self-evaluations, time perspectives, motivation for school and their achievement in different countries and at different ages

The present study focused on the relations between the self-efficacy, social self-concept, time perspectives, school investment and academic achievement of students in four different European countries and in different adolescence periods. A total of 1623 students completed questionnaires. The relations between the concepts proved not to be specific to the Western or to the former Communist bloc countries studied. The expected general decline in investment and academic achievement over the adolescence period showed up in all four countries studied. Contrary to our hypothesis, however, this decline could not be explained by growing influences of either social self-concept or time perspectives regarding personal development on their investment. In fact, the effects of social self-concept were strongest for the youngest adolescence group. Students’ social self-concept was the best predictor for their investment, while self-efficacy proved to predict academic achievement best in all adolescence periods.

Mögliche Auswirkungen eines Handels- und Investitionsschutzabkommens EU-USA auf die Schweiz

Die gegenwärtigen Bemühungen für ein umfassendes Handels- und Investitionsschutzabkommen zwischen der EU und den USA werden nicht ohne Auswirkungen auf die Schweiz bleiben. Eine Studie des World Trade Institute der Universität Bern im Auftrag des Staatssekretariats für Wirtschaft analysiert die möglichen Auswirkungen eines Abkommens auf die Schweizer Wirtschaft und auf die Handelsbeziehungen der Schweiz. Unterschiedliche Szenarien führen dabei zu unterschiedlichen Auswirkungen.
