Forskningsöversikt (refereegranskat)abstract
- The aims of this scoping review were to map the current literature on interventions for improving mental health in athletes, identify knowledge gaps, and generate future research questions. The Preferred Reporting Items for Systematic Review and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guided this review. A systematic literature search was conducted in SPORTDiscus, PsycINFO, and SCOPUS and 44 intervention studies met the inclusion criteria. Results showed that 22 studies (50%) implemented cognitive behavioural principles, and the majority of these studies were influenced by various mindfulness programmes. Most studies (93%) included healthy athlete samples, and athletes aged 15–19 were the most examined age group (43%). Only three studies used clinical criteria in their sampling of participants and mediators were examined in two studies. The scarcity of studies examining mediators and subclinical or clinical samples revealed critical knowledge gaps in the literature. Furthermore, the critical appraisal showed that regardless of study design, most studies demonstrated low internal validity. We propose the use of high-quality single-case studies with athletes who experience subclinical or clinical mental health issues, and further investigation of mechanisms of change linking intervention components to outcomes of interest.

A framework for raw materials management in process industries
- 2013
-
Konferensbidrag (refereegranskat)abstract
- Firms in the process industries manipulate materials properties to produce upgraded raw materials for applications and products upstream in a supply chain. About 25% of the most research intensive firms in the world belong to the process industries, so proper management of raw materials is a key concern for many firms. This article explores the concept of “raw materials management”. By studying the current world leader in powder metallurgy, the Höganäs Corporation, the article describes the external and internal factors impacting how raw materials are managed, and how raw material issues affect different aspects of firm performance. Managerial implications are presented elaborating three key-areas that firms should deal with when developing a strategic approach to raw materials management.

Tidskriftsartikel (refereegranskat)abstract
- Burnout is a construct that has garnered considerable attention in sport psychology within recent years. Several hypothesized models regarding how the three dimensions (exhaustion, devaluation, and reduced sense of accomplishment) temporally relate to each other have been advanced. One proposal outlined by Maslach and Leiter suggests that exhaustion predicts devaluation which predicts reduced sense of accomplishment. However, there is no consensus among researchers as it has been argued that exhaustion predicts devaluation and reduced accomplishment separately. The aim of this study was to test multiple alternative hypotheses regarding the relationships of the burnout dimensions in athletes. Two samples of Swedish youth elite athletes with differing time spans between measurements were used. Specifically, one sample involved time-intensive measures collected every week over an eight-week period, and the other sample included four measurement points across an 18-month period. Results showed that none of the previously proposed models outlining the temporal relations of burnout dimensions were supported. Statistical analysis of the models including the cross-lagged predictions of dimensions did not have any statistically significant impact except when exhaustion negatively predicted devaluation between time 1 (month 0) and time 2 (month 6) in the 18-month sample; this relation faded in the following time points. Further, issues regarding the stability of devaluation and reduced sense of accomplishment emerged as their autocorrelation were very weak in the time-intensive sample. These findings raise a number of points for further theoretical and practical discussions about the athlete burnout construct.
