There is a growing awareness of the complex and largely negative attitudes many girls in the UK hold towards physical activity in general and Physical Education (PE) in particular. This research in the UK involves a qualitative study of six Year 9 girls' experiences and motivations in PE.Reflexive interpretation and biographical analysis of in-depth interviews are utilized to explore the themes of the relationship between “sportiness” and heterosexual desirability; and the polarized images of “tomboy” and “girlie.” Work by Connell [Connell, R.W. (1987). Gender and power. Cambridge: Polity Press.] on the gender order, and theories arising from the cultural analysis tradition on teenage girls' subcultures and identity formation are drawn on in order to make sense of the girls' narratives.The findings of this research reveal that images of teenage girls and young women being physically active are non-congruous with the traditional ideologies of acceptable femininity. This paper describes how these girls negotiate the contradictions and the tensions caused by the “femininity deficit” incurred in PE by creating “double identities” and living “split lives.” 相似文献

One aspect of the multifaceted controversy on value change in advanced industrial societies concerns the measurement of values. Analyses of 1976–86 Euro-Barometer data have indicated that responses to the four-item “materialist-postmaterialist” values index are very sensitive to current economic conditions, especially inflation and unemployment rates and, hence, much of the recorded increase in postmaterialism in eight Western European countries since the mid-1970s is artifactual. Although it has been claimed these findings disappear if more recent data are considered, time series analyses reveal that responses to the values measure are strongly affected by prevailing economic conditions throughout the entire 1976–92 period. These aggregate-level findings are buttressed by individual-level analyses of 1989 Euro-Barometer data. 相似文献

Eighteen external quality assessment (proficiency testing) samples were prepared from client specimens collected with the Intercept oral fluid collection device and by spiking drug-free oral fluid. Samples were circulated in pairs at quarterly intervals to 13 UK and USA based laboratories for analysis by a panel of OraSure micro-plate Intercept enzyme immunoassay kits and hyphenated mass spectrophotometric techniques. During the survey, there was a single case of non-specificity in a false report for methadone. The major errors were of lack of sensitivity relative to the concentration thresholds specified for the immunoassays. The sensitivity for overall "present"/"not found" reports calculated as true positives/(true positives+false negatives) were for the amphetamine specific assay 50%, methyl-amphetamines 93%, barbiturates 64%, cannabinoids 73%, cocaine and metabolites 100%, benzodiazepines 69%, methadone 95%, opiates 79% (opiates excluding oxycodone 93%), phencyclidine 93% and human gamma-globulin 97%. A small number of the sensitivity errors were attributable to errors in chromatographic confirmation techniques. 相似文献

The eruption and mineralization of third molars are the main criteria for dental age estimation of living people involved in criminal proceedings. Since the development of third molars is usually completed by the age of 19 or 20 years, this feature cannot be used to ascertain whether a person has attained the forensically relevant age of 21 years. This study examined whether the DMFT index or the third molar DFT index could supply reliable information enabling conclusions to be drawn about whether a person has reached the age of 21. To this end, 650 conventional orthopantomograms of German subjects aged 18 to 30 years were evaluated. The DMF index variations considered were found to be unsuitable for determining whether a person is over 21 because they displayed a weak correlation with age and considerable individual scatter. A high indicative value can only be attributed to a third molar DFT index of 4, although this is rarely observed in the relevant age group. An X-ray examination of the medial clavicular epiphyseal cartilage is, therefore, strongly recommended when assessing whether a person has attained 21 years of age. 相似文献

The present study examined the relationships between specific anxiety, mood disorders, levels of hopelessness, and suicide ideation. The sample consisted of 606 outpatients recruited from several psychiatric settings. It was found that dysthymia was significantly associated with hopelessness. Patients presenting major depressive episode with higher anxiety symptoms had significantly increased scores on the hopelessness scale. Major depressive episode and bipolar disorder, but not dysthymia, were significantly associated with higher levels of suicide ideation. Increased levels of anxiety symptoms in patients with dysthymia were associated with increased levels of suicide ideation, while increased depressive symptoms in patients with specific phobia and generalized anxiety disorder were associated with significantly lower levels of suicide ideation. The findings suggest that depressive disorders, but not anxiety disorders, constitute risk for suicide. Moreover, the differentiation between a depressive and an anxiety disorder as the principal diagnosis, as well as the assessment of anxiety-level symptoms in patients with major depressive episode and dysthymia, seems of special relevance when assessing suicide risk. 相似文献
