The role of quality relationships and communication strategies for the fulfilment of secure and insecure athletes' basic psychological needs.

The correlates of coach-athlete relationship quality have been the focus of research for over a decade; however, little is known about the mediating and moderating mechanisms underlying these associations. The present study conducted a moderated mediation analysis to examine (a) the mediating role of communication strategies (via COMPASS) on the association between the quality of the coach-athlete relationship and athlete psychological needs satisfaction and (b) whether individual differences in athletes' attachment style (secure, anxious, avoidant) moderates the mediational relationship. 350 Swedish athletes representing a range of sports and competition levels completed a multi-section questionnaire.

Mental Health in Athletes: Where Are the Treatment Studies?

In recent years, athletes' mental health has gained interest among researchers, sport practitioners, and the media. However, the field of sport psychology lacks empirical evidence on the effectiveness of psychotherapeutic interventions for mental health problems and disorders in athletes. Thus far, intervention research in sport psychology has mainly focused on performance enhancement using between-subject designs and healthy athlete samples.

Bioaccumulation of PCB congeners in marine benthic infauna.

Field concentrations of polychlorinated biphenyls (PCBs) were measured in sediment and nine marine soft bottom invertebrate species. Lipid- and organic carbon normalised biota-sediment accumulation factors (BSAFs) were determined for 29 nonplanar and 11 coplanar congeners. To investigate whether the bioaccumulation was in thermodynamic equilibrium with the sediment, the determined BSAFs were compared to theoretically calculated ones to obtain a BSAFdet.

Effects of antifouling paint components (TBTO, copper and triazine) on the early development of embryos in cod (Gadus morhua L.).

To assess the risk of antifoulant use to the commercially important cod (Gadus morhua L.), fertilised cod eggs were exposed to triazine, copper and TBTO singly or combined in laboratory tests with running seawater. At the highest tested concentrations (11.

Occurrence and effects of organotins on adult common whelk (Buccinum undatum) (Mollusca, Gastropoda) in harbours and in a simulated dredging situation.

Transplanted common whelk (Buccinum undatum) (Mollusca, Gastropoda) accumulated fairly high levels of organotins (tributyltin (TBT) and triphenyltin (TPT)) during exposure in three harbours with different TBT contamination. This did not though lead to an increase in imposex frequency in the adult females studied. Simulating harbour dredging in an experiment using suspended sediment from one of the harbours only resulted in a low concentration of TBT in the tissues of the common whelk and subsequently no changes in the occurrence and degree of imposex.
