- The aim of the study was to provide a standardisation of self-reported competencies and emotional/behavioural problems among Swedish adolescents, using the Youth Self-Report (YSR). The YSR was completed by 2522 adolescents aged 13-18 years, recruited from secondary and upper secondary schools in different regions in Sweden. The results showed that effects of gender and age were small but significant with girls scoring higher than boys on most problem scales, and 15- to 16-year-olds scoring higher than younger and older adolescents on the problem scales. Small effects were also found for residence as well as for parental SES. The correlations between internalising and externalising problems were 0.51 for boys and 0.49 for girls, whereas the correlation between competence and problem scores was low. We conclude that the individual variation in YSR-scores is much greater than can be attributed to factors such as gender, age, SES, or residential area. Consequently, the YSR has the potential to serve as an instrument for assessing individual adolescents' self-reported competencies and problems in Sweden. Given the almost orthogonal relation between self-reported competencies and problems, the competence scale is surprisingly little used in psychopathology research.

Monitoring of persistent organic pollutants (POPs): Examples from Lake Vattern, Sweden
- 2001

Ingår i: Ambio: a Journal of Human Environment. - 0044-7447. ; 30:8, s. 545-551

Tidskriftsartikel (refereegranskat)abstract
- Lake Vattern in southern Sweden is a large oligotrophic lake with high surface to catchment area ratio (ca. 0.4) and a water residence time of 60 years. The lake combines sensitivity to atmospheric POP-pollution with general susceptibility for effects of POPs and slow concentration decline. Time series, from the 1960s until 1996, of PCBs and DDT in fish and data on TCDD in sediment of L. Vattern are presented and compared to other large lakes. The long time dataset of POPs in Arctic char (Salvelinus salvelinus) shows a significant annual decline of about 5% for PCBs and 13% for DDT. These rates are in agreement with other studies. Nutrients as well as biological effects and factors affecting the fate of POPs in oligotrophic lakes with long residence times are discussed. We propose that oligotrophic clear lakes are important ecosystems for monitoring POPs in biota.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This short essay on how the book is used in Dutch paintings of the 16th and 17th centuries stresses the ambiguities of its overt message and latent symbolism, more varied than mere erudition or inevitable mortality.
