Media use and school achievement – boys at risk?

In work done at the German Criminological Research Institute of Lower Saxony (KFN) various methods have been used to investigate how specific inappropriate media usage patterns affect academic performance in children and adolescents. The findings are paralleled by current international research indicating a negative relationship between these two variables. Based on a cross‐sectional survey of 5,529 fourth grade students and a longitudinal panel study with 1,157 primary schoolchildren, a key finding can be demonstrated: the more time students spend on consuming media and the more violent its contents are, the worse are their marks at school, even when controlling for vital factors such as family, educational, or immigrant background. In particular, boys who gender‐specifically are better equipped with electronic media devices, who partially have extensive media usage times and who strongly prefer violent media content, are at the risk of showing poor school performance. In fact, a decrease in academic performance of boys can be observed in German school statistics. By presenting first results of a school‐based intervention programme, a promising approach to the reduction of detrimental effects of electronic media use on school performance is introduced.     

Labeled Calculi and Finite-Valued Logics

A general class of labeled sequent calculi is investigated, and necessary and sufficient conditions are given for when such a calculus is sound and complete for a finite-valued logic if the labels are interpreted as sets of truth values (sets-as-signs). Furthermore, it is shown that any finite-valued logic can be given an axiomatization by such a labeled calculus using arbitrary "systems of signs," i.e., of sets of truth values, as labels. The number of labels needed is logarithmic in the number of truth values, and it is shown that this bound is tight.     

An exploration of health-seeking behaviours among Nigerian Christians in the UK: towards enhanced health services utilisation

Migration from different cultures carries with it some acclimatisation challenges. This study explored various health-seeking behaviours and potential barriers to healthcare utilisation among Nigerian Christians in the UK. This qualitative study involved 10 adult male and female participants, with both interviews and focus group discussion (FG) for data collection (Interviews: n?=?4, FG: n?=?6). Thematic analysis revealed that religious and cultural beliefs were barriers to healthcare utilisation. The implication is that further research on cultural matching between care providers and service users is needed; where religious leaders and health providers from Nigeria can influence health decisions among this migrant community. Limitations of the current study are discussed, with directions for further research identified.
