The purpose of this study was to test hypotheses regarding (1) relations among negative affect and hormones of gonadal and adrenal origin in young adolescents, at three times of measurement, over a one-year period; and (2) stability of negative affect. The sample consisted of 10- to 14-year-old boys (N=56) and 9- to 14-year-old girls (N=52). The adolescents were assessed three times at 6-month intervals over one year. Serum levels of gonadotropins, gonadal steroids, adrenal androgens, and cortisol were assessed, as well as stage of pubertal development (Tanner criteria). The negative affect assessments consisted of self-report questionnaire and interview measures of anxiety and depressive affect, as well as mother reports of internalizing behavior problems. In the concurrent (cross-sectional) analyses, boys reporting higher levels of negative affect tended to be those at higher genital stage or older age, with lower testosterone and cortisol levels and lower dehydroepian-drosterone sulphate levels. In the longitudinal analyses, negative affect, and to a lesser extent hormone levels at the first time of measurement predicted negative affect 12 months later. The findings suggest that puberty-related hormone levels should be considered along with psychological characteristics in examining the processes involved in the development of negative affect during the pubertal years.Received Ph.D. from The Pennsylvania State University.

Body image and weight loss beliefs and behaviors were assessed in 341 female and 221 male high school students. Estimates of body dissatisfaction varied depending on the measurement strategy used. Despite having similar weight distributions around the expected norm, girls were significantly more dissatisfied with their bodies than boys. Body Mass Index was positively related to body dissatisfaction in girls and boys, while higher exercise levels were related to higher body satisfaction in boys. Nearly two-thirds of girls and boys believed being thinner would have an impact on their lives, but the majority of girls believed this would be positive while the majority of boys believed this would be negative. Thirteen percent of female subjects reported using one or more extreme weight loss behavior at least weekly. Beliefs regarding the effectiveness of different weight loss measures were assessed. Weight loss behaviors in this Australian sample appear similar to comparable U.S. samples.Received Ph.D. from University of Tasmania.

It is usual for electoral analysts to calculate the swing necessary at the next election to unseat a government, assuming that the swing is a uniform one. However, swings are not uniform. The non-uniform swing which would, on average, unseat a government is shown to be different from the uniform swing. For example, at the next Australian election for the House of Representatives, a uniform swing of 1.5 per cent against the current government would cause it to lose five seats, leaving it in a minority of 73 out of 148 seats, but a non-uniform swing of only 0.8 per cent would, on average, have the same effect. Implications of this variability for the size of the majority, the possibilities of a Parliament with an even number of seats being equally-divided, and the use of this analysis to detect gerrymandering and to correct for it, are considered.  相似文献

The present government of Bangladesh has extensively reformed the administrative system and upgraded the previous thana to upazila (sub-district) to serve as the focal point of development administration. A new tier of local government called Upazila Parishad (UZP) has been created and a large number of functions have been devolved to this institution along with the placement of central government employees at its disposal. The reformers argue that the present system will remove the inadequacies of the previous administrative system and will bring about an improvement in the co-ordination of field services at the upazila level. However, the actual situation represents a totally different picture. The desired integration— both vertical and horizontal—and co-ordination in local level planning is non-existent due to the absence of any clear direction from the central government. Proper co-ordination among the field services in the upazila administration does not exist due to the anomalous relation between the upazila and the national government, including excessive central control; the involvement of multiple agencies of the central government in guiding and supervising; ambiguity in government thinking; the absence of clarification from the ministries concerned and agencies on the timing of different development programmes; and conflict over the allocation of resources. There is also conflict between the different tiers of local government in respect of authority and resources. Relations between public representatives and officials at the upazila level are strained because a clear allocation of authority to political executives is lacking; areas for co-operation among different agencies have not been clarified; and public representatives and government officials lack mutual respect.  相似文献
