This experiment examined the hypothesis that neutral contextual features of a virtual environment become associated with aggressive meaning and acquire the function of primes for aggressive cognitions. Seventy-six participants were assigned to one of two violent video game conditions that varied in context (ship vs. city environment) or a control condition. Afterwards, they completed a Lexical Decision Task to measure the accessibility of aggressive cognitions in which they were primed either with ship-related or city-related words. As predicted, participants who had played the violent game in the ship environment had shorter reaction times for aggressive words following the ship primes than the city primes, whereas participants in the city condition responded faster to the aggressive words following the city primes compared to the ship primes. No parallel effect was observed for the non-aggressive targets. The findings indicate that the associations between violent and neutral cognitions learned during violent game play facilitate the accessibility of aggressive cognitions.

A1 - Dumont, Hanna A1 - Trautwein, Ulrich T1 - Tracking Effects Depend on Tracking Type BT - An International Comparison of Students’ Mathematics Self-Concept JF - American Educational Research Journal N2 - The aim of the present study was to examine how different types of tracking— between-school streaming, within-school streaming, and course-by-course tracking—shape students’ mathematics self-concept. This was done in an internationally comparative framework using data from the Programme for International Student Assessment (PISA). After controlling for individual and track mean achievement, results indicated that generally for students in course-by-course tracking, high-track students had higher mathematics self-concepts and low-track students had lower mathematics self-concepts. For students in between-school and within-school streaming, the reverse pat- tern was found. These findings suggest a solution to the ongoing debate about the effects of tracking on students’ academic self-concept and suggest that the reference groups to which students compare themselves differ according to the type of tracking.

Compared with the vast amount of studies concerning environmentally conscious consumer behaviour, relatively little is known about socially conscious consumption. The present paper focuses on fair consumption as an important aspect of social consumption. In our study, consciousness for fair consumption (CFC) is defined as a latent disposition of consumers to prefer products that are produced and traded in compliance with fair labour and business practices. A scale to measure CFC was conceptualized and tested in three independent empirical studies. Two studies were conducted at European universities (2010 and 2012) and used 352 and 362 undergraduate business students respectively. The third study, conducted in 2011, used 141 employees at a European university. The results confirmed the reliability and validity of the new CFC scale across samples. While being moderately related to other aspects of sustainable consumption such as ecological concern and moral reasoning, CFC was significantly distinct from those concepts. Most importantly, it was established that the CFC, as measured by the new CFC scale, is a strong determinant of consumption of fair trade products that has been neglected in existing research.

For institutions promoting societal change, as well as for companies being confronted with growing expectations regarding compelling contributions to sustainable changes, it is of great importance to know if, and to what extent, consumers have already internalized the idea of sustainability. Against the background of existing research gaps regarding a comprehensive measurement of the consciousness for sustainable consumption (CSC), the authors present the result of a scale development. Consciousness was operationalized by weighting personal beliefs with the importance attached by consumers to sustainability dimensions. Four separate tests of the CSC scale indicated an appropriate psychometric quality of the scale and provided support for this new measurement approach that incorporates the environmental, social and economic dimensions of sustainability.

Controlling for financial and nonfinancial household variables, we show that self-employed households particularly use personal overdrafts significantly more often than employee households. When analysing the correlation between consumer loan take-ups and consumption of self-employed in comparison to employee households, we find first evidence that overdrafts are used by self-employed to finance their business as well. This indicates that intermingling constitutes a financing strategy when regular business loans might not be accessible.

HK620TSP binds hexasaccharide fragments with low affinity, but single amino acid exchanges generated a set of high-affinity mutants with submicromolar dissociation constants. Isothermal titration calorimetry showed that only small amounts of heat were released upon complex formation via a large number of direct and solvent-mediated hydrogen bonds between carbohydrate and protein. At room temperature, association was both enthalpy- and entropy-driven emphasizing major solvent rearrangements upon complex formation. Crystal structure analysis showed identical protein and sugar conformers in the TSP complexes regardless of their hexasaccharide affinity. Only in one case, a TSP mutant bound a different hexasaccharide conformer. The extended sugar binding site could be dissected in two regions: first, a hydrophobic pocket at the reducing end with minor affinity contributions. Access to this site could be blocked by a single aspartate to asparagine exchange without major loss in hexasaccharide affinity. Second, a region where the specific exchange of glutamate for glutamine created a site for an additional water molecule. Side-chain rearrangements upon sugar binding led to desolvation and additional hydrogen bonding which define this region of the binding site as the high-affinity scaffold.
