The number of people accessing the Internet for sexual purposes (cybersex) has increased dramatically over the last 10 years. However, little research has been conducted to determine how frequently clients present for treatment with cybersex‐related issues. One hundred sixty‐four clinical members of the American Association for Marriage and Family Therapy participated in the current study, which was conducted to identify the impacts of cybersex on MFTs’ practices. Most respondents report seeing clients with cybersex‐related issues, with client numbers increasing over the past 2 years. Although most respondents felt prepared to diagnose and treat adults with cybersex problems, half felt unprepared to diagnose and treat children. Lastly, most respondents reported that their required college courses were not helpful in preparing them to diagnose and treat cybersex‐related problems. The implications of study findings are discussed. 相似文献

We describe a class of models for the investigation of possible raised risk of disease around putative sources of environmental pollution. An adaptation of the point process method suggested by Diggle and Rowlingson is presented, allowing the use of routinely available aggregated data and incorporating the more general distance–risk model suggested by Elliott and co-workers. An application to data on cancers of the stomach around municipal solid waste incinerators is presented. 相似文献

The following conversation describes a narrative means of uncovering (or ‘deconstructing’) some of the invisible forces that undermine parents' capacities in caring for their children in preferred ways. In the authors' experience, parents can be hugely resourceful and provide a clear account of what they ‘should’ be doing, yet seem unable to act upon their own good advice — it is as though an external agent, named below as ‘Virus X’, prevents them from being the parents they would like to be. Through naming this external agent, identifying its influences and noticing parents' acts of resistance in the face of these influences, antidotes to Virus X can be developed. This paper describes the development of such an approach within a child behaviour management group. In keeping with the playful approach encouraged by narrative therapy, the authors of this paper join forces to act as investigative journalists in exposing Virus X to the readers. 相似文献

This article examines the consequences of the return to Africa of donors that are not members of the OECD's Development Assistance Committee (DAC). It categorises these donors according to form, content, size and modality of their aid. It finds that their return increases external financial flows, in particular to countries not targeted by DAC donors. Moreover, for some donors like China and India the flows are closely related to other financial flow s such as trade and investment. Furthermore, it finds that the return of non‐DAC donors may conflict with plans to harmonise aid and may simultaneously raise transaction costs for recipients. 相似文献

Starting from the assessment that past efforts at reform in agricultural water management in developing countries have achieved very little, this article argues that a fundamental change is required in the approach to policy and institutional transformation if the present deadlock in the internalisation of ecological sustainability, human development/poverty alleviation and democratic governance into the ‘core business’ of water bureaucracies is to be overcome. ‘Social engineering’ approaches need to be replaced by ‘strategic action’ approaches that acknowledge the inherently political character and the plurality of actors, institutions and objectives of water management — a perspective operationalised here around the notions of ‘problemshed’ and ‘issue network’. 相似文献

Summary. We analyse data from a study involving 173 pregnant women. The data are observed values of the β human chorionic gonadotropin hormone measured during the first 80 days of gestational age, including from one up to six longitudinal responses for each woman. The main objective in this study is to predict normal versus abnormal pregnancy outcomes from data that are available at the early stages of pregnancy. We achieve the desired classification with a semiparametric hierarchical model. Specifically, we consider a Dirichlet process mixture prior for the distribution of the random effects in each group. The unknown random-effects distributions are allowed to vary across groups but are made dependent by using a design vector to select different features of a single underlying random probability measure. The resulting model is an extension of the dependent Dirichlet process model, with an additional probability model for group classification. The model is shown to perform better than an alternative model which is based on independent Dirichlet processes for the groups. Relevant posterior distributions are summarized by using Markov chain Monte Carlo methods. 相似文献

We conduct a comprehensive examination of the gender differences in pay focusing on multiple perspectives emanating from economics, social psychology, and gender studies. Data are drawn from surveys of MBA students conducted by the Graduate Management Admissions Council. Although women in both samples earn significantly less on average than men, when the effects of the study's variables are considered via multiple regression analysis, no significant difference in annual salary is observed. Our results show the importance of simultaneously considering the impact of human capital, job and firm characteristics, demographics, and cognitive skills. Structural differences are noted in the models estimated separately for men and women. However, the results from decomposing salary differentials are quite consistent with estimates from the single-equation models. 相似文献
