Drawing on recently completed research funded by the Departmentof Health, this article examines the extent of strain on thefoster carers of adolescents, its influence on parenting practicesand the overall impact on placement outcomes. The research find­ingsshow that foster-carers’ parenting capacity was markedlyreduced in a number of specific areas when they had experienceda high number of stressful life events in the six months priorto the young person’s arrival or were under considerablestrain during the placement. Conduct problems, hyperactivityand violent behaviour by the young people increased carer strain,as did contact difficulties with the children’s families.Problems in contacting social workers were linked to elevatedstrain, whilst strain was lessened when carers received helpfrom friends or from local professionals. Signifi­cantlyhigher disruption rates were experienced by strained carersand these placements were also less beneficial to the youngpeople.  相似文献

This paper examines the domestic labour arrangements of cohabiting couples and the implications for gender equality. The discussion is based on a predominantly qualitative study of thirty young cohabiters. The men and women shared domestic labour in diverse ways but not equally, instead they used discursive strategies to avoid assessing whether their contributions were equal. The cohabiters expressed extremely egalitarian attitudes when asked general questions about society but equality is absent when they discuss their own relationships. I argue that the concept of equality is part of public discourse rather than a fundamental principle of cohabiting relationships.  相似文献

In the past few years, the field of dam safety has approached risk informed methodologies throughout the world and several methodologies and programs are appearing to aid in the systematization of the calculations. The most common way of implementing these calculations is through the use of event trees, computing event probabilities, and incremental consequences. This methodology is flexible enough for several situations, but its generalization to the case of systems of several dams is complex and its implementation in a completely general calculation methodology presents some problems. Retaining the event tree framework, a new methodology is proposed to calculate incremental risks. The main advantage of this proposed methodology is the ease with which it can be applied to systems of several dams: with a single risk model that describes the complete system and with a single calculation the incremental risks of the system can be obtained, being able to allocate the risk of each dam and of each failure mode. The article shows how both methodologies are equivalent and also applies them to a case study.  相似文献

This paper describes the results of a self‐reporting dairy completed by 186 male sex workers (MSWs) over a 2‐week period in Brisbane, Sydney, and Melbourne, Australia. The diary was completed following each commercial sex encounter by the MSW. The results reveal that MSWs reported 2088 commercial sex encounters during the study period, with an average of 11.2 encounters per MSW. The majority of sex encounters took place in either the client's or the MSW's residence, with significant variations by city. The average sexual encounter lasted 70 minutes, and comprised two sexual acts, masturbation and oral sex. Condom use was reported in 67.4% of all the encounters. Using the AIDS Council safe‐sex classification system, the majority of the commercial sex encounters fell in the “safer sex” category; however, there were significant differences by source of clients and place of the encounter. Use of drugs and alcohol reveal interesting patterns: Clients were more likely to use alcohol, while MSWs had significant differences of usage of the different drugs. This study demonstrates that the majority of MSWs are offering and practicing safe sex behaviours, however, MSWs working in the street setting are still likely to be practising unsafe sex. Male sex work is becoming an organised business and this provides opportunities to implement further public health interventions.  相似文献

Abstract

Objectives: To evaluate whether daytime sleepiness, poor sleep quality, and morningness and eveningness preferences are associated with common mental disorders (CMDs) among college students. Methods: A total of 963 college students completed self-administered questionnaires that collected information about sociodemographic characteristics, sleep quality characteristics, CMDs, and other lifestyle behaviors. Results: The prevalence of CMDs was 24.3% (95% confidence interval [CI] [21.5%, 27.1%]) among all students. Prevalence estimates of both excessive daytime sleepiness and poor sleep quality were higher among females (35.4% and 54.4%) than males (22.0% and 45.8%). Cigarette smoking was statistically significantly and positively associated with having CMDs (p = .034). Excessive daytime sleepiness (odds ratio [OR] = 3.65; 95% CI [2.56, 4.91]) and poor sleep quality (OR = 4.76; 95% CI [3.11, 7.29]) were associated with increased odds of CMDs. Conclusion: Given the adverse health consequences associated with both sleep disorders and CMDs, improving sleep hygiene among college students is imperative to public health.  相似文献

The worldwide movement of highly skilled workers (cadres) in transnational corporations has long been known to literature in the field, yet has not been thoroughly researched. The mechanisms governing their international circulation are, in themselves, somewhat specific. The fact that they use an organizational “channel” for migration means that the constraints differ from those that act on “independent” economic migrants with either low or high levels of skill (the so‐called brain drain). This article focuses on some of the manifestations of this mobility. Its dependence on a set of variables can be considerable: the firm's development phase, investment target choice, leading activity (manufacturing or services), form of technology, type of firm (using greenfield or brownfield investment), whether a firm acquired is healthy or undergoing an economic crisis, and nationality or corporate culture. The occupational insertion of cadres leads to further constraints: while the strictly “technical” assignments generally stem from skill shortages, the general “management” appointments mainly result from questions arising from control and trust. As a whole, the flows of highly skilled workers seem to be related to multiple variables – either social, organizational or individual – which make it difficult to predict future trends.  相似文献

When Ian Wilson and Carlos Barahona of the Statistical Services Centre at the University of Reading were asked to review an evaluation of the effectiveness of an aid package in Malawi, they expected a simple enough task. But few things in the developing world are simple. Where aid for the poorest is concerned, is evidence collected and analysed with enough rigour to enable well-informed decisions to be made?  相似文献
