Determination of the prevalence of anabolic steroids,stimulants, and selected drugs subject to doping controls among elite sport students using analytical chemistry

Abstract

Drug abuse by adolescents has been investigated in various surveys that reported correlations between age, gender, and activity. However, none of these studies included chemical analyses to help substantiate the statements of participants. In the present study, the urine specimens of 964 students (439 females, 525 males; mean age 22.1 years, s = 1.7), who applied to study sports sciences at university, were assessed for anabolic steroids, stimulants, and selected drugs prohibited in sports. In total, 11.2% of the urine specimens provided contained drugs covered by doping controls. The most frequently detected compound was the major metabolite of tetrahydrocannabinol (9.8%) followed by various stimulants related to amphetamine and cocaine (1.0%). Indications of anabolic steroid use were found in 0.4% of urine samples but originated from contraceptives containing norethisterone. The present study provided unambiguous data on the status quo of drug (ab)use by adolescents hoping for a career related to elite sport or sports sciences. No use of anabolic steroids was detected. However, evidence for stimulants and tetrahydrocannabinol administration was obtained, although not reported by any participant, which highlights the issue of under-reporting in surveys based solely on questionnaires.

Sport under the Nazis in Norway, 1940–45

Summary

The Nazis won the battle of Skarphedin after a long struggle with the anti‐Nazis, but did not succeed in gaining the support of the ordinary members of the club. They controlled the club activities from July 1941 till the end of the war, but very few competitions were arranged and very few members took part. The Nazisseemed to control the board, the athletics and the soccer group, but not theski group. The last mentioned group made their own report from the war and to some extent they took part in ‘illegal’ competitions that were not controlledby the Nazis. The reasons why Skarphedin was taken over by the Nazis should be seen in the light of Bø's geographical location in the heart of Telemark, the economic crisis of the smallholders, and the electoral pact between the Norwegian Nazi Party and Bygdefolkets Krisehjelp. In many ways Bø appears to have been a Nazi centre during most of the war years, even if the majority ofits inhabitants did not involve themselves actively on any of the fronts.     

On the methodological problems of new ideas and approaches to press concentration research

This article considers various European approaches to press concentration research, analyzing their individual strengths and weaknesses. The author argues that research on concentration has not kept pace with press developments and that the weaknesses in the separate approaches to exploring concentration have obscured the real nature and extent of the problem. He then offers a model for concentation research that integrates the various approaches to provide a broader understanding of the effects of press concentration.     

Methods of Teaching and Class Participation in Relation to Perceived Social Support and Stress: Modifiable factors for improving health and wellbeing among students

Social support and stress have previously been found to be predictors of health among students. In this study, we investigated whether methods of teaching and class participation were related to social support and stress via questionnaire responses from 947 Norwegian adolescents aged 13-15. Linear associations between the variables were assessed in univariate and multivariate analyses of covariance. Highly significant overall effects were found with the amounts of group work, class discussions, and verbal activity. Borderline significant effect was also seen in relation to the amount of independent work. An increasing amount of group work increased the perception of social support from teachers and peers, but showed no significant association with stress. Increasing amounts of class discussions were significantly related to increasing perception of social support, in particular among boys. Class discussions also seemed to reduce the experience of stress, although somewhat inconsistently. Increasing amounts of independent work increased stress, but also increased the perception of social support from peers among boys. No significant associations with traditional teacher instruction were found. Verbal activity was strongly related both to increasing perception of social support and decreasing experiences of stress. In view of the present results, participatory learning activities may promote health by preventing stress experience and promoting social relationships.     

Does sensitivity to orthographic regularities influence reading and spelling acquisition? A 1-year prospective study

Recent studies focused on the influence of orthographic processing on reading and spelling performance. It was found that orthographic processing is an independent predictor of reading and spelling performance in different languages and children of different ages. This study investigated sensitivity to orthographic regularities in German-speaking children (N = 31) prior and during formal reading and spelling instruction. In addition, the relationship between sensitivity to orthographic regularities and reading and spelling performance was explored. Two aspects of children’s sensitivity to orthographic regularities (sensitivity to frequent double consonants and sensitivity to legal positions of double consonants) were measured with a nonword forced choice task. The results show that sensitivity to orthographic regularities improved significantly from kindergarten to first grade. Moreover, children’s sensitivity to orthographic regularities at the end of first grade accounted for a significant amount of unique variance in their reading and spelling performance. These results suggest that orthographic sensitivity on a sublexical level is important for the development of reading and spelling skills.     

Genealogy and educational research

The aim of this paper was to demonstrate how genealogy can be used as a method for critical education research. As Foucault emphasized, genealogy is a method for identifying the way in which the individuals are subjectified through discourse. The genealogical analysis in the article defines two mayor tendencies in contemporary Danish pedagogy: individualization and structuralizing. The analyses also show an example of how the two tendencies are intermingled in the Danish law of learning plans in day care institutions.
