As approaches to positive youth development (PYD) gain momentum, the issue of sexuality – a critical component of human development – is being subsumed by ideological debates. In the current political climate, sexuality education is often relegated to biological and/or values-based approaches, neglecting essential relational and collective aspects of sexuality. Through the explication of sexuality as an important component of youth's social ecology, this paper provides a conceptual link between the goals of the Sexuality Information and Education Council of the United States' (SIECUS) Guidelines for comprehensive sexuality education and those of PYD. We argue that sexuality, as a normative part of human development, culture, identity, and relationships, be approached from an asset-based perspective, rather than a deficit-based perspective. We propose a framework that illustrates how aspects of sexuality are embedded within PYD contexts, and demonstrates how a sexuality education program rooted in SIECUS guidelines can further PYD goals across community contexts.  相似文献

Qualitative research in the UK has revealed a diversity of financial arrangements underlying separate systems of household financial management. One factor, identified in previous work, is perceived ownership of money, with financial practices differing according to whether couples have distinct, blurred or shared ownership perceptions. The present work aims to build on and extend this research, using data from an online survey study with 190 cohabitants in the UK. The findings reveal that ownership perceptions transcend separate money management categories, and can be a significant predictor of the type of contribution cohabitants make towards joint household expenses.  相似文献

This study reports preliminary findings regarding the feasibility and efficacy of a novel couple-based treatment, named Strategic Approach Therapy (SAT), for reducing avoidance symptoms of posttraumatic stress disorder (PTSD). Six male Vietnam combat veterans diagnosed with PTSD and their cohabitating marital partners participated in 10 weeks of SAT treatment. Self-report, clinician ratings, and partner ratings of PTSD symptoms were obtained before the first session and after the tenth session of treatment. Veterans reported statistically significant reductions in self-reported, clinician-rated, and partner-rated effortful avoidance, emotional numbing, and overall PTSD severity. These data indicate that SAT offers promise as an effective treatment for PTSD avoidance symptoms.  相似文献

This paper explores the errors involved in the approximation of both the maximum and sum of two independent Beta random variables, each by another Beta random variable. The principal area of application is the time analysis of PERT networks, and the results are interpreted and discussed in terms of this application. The error was found to be acceptable for the greater part of the range of the parameters involved. The results will help practitioners estimate the mean and standard deviation of the completion time of PERT networks.  相似文献

'Stakeholding' is a term laden with manymeanings. In this paper we attempt to put someorder on the discourse by confining attentionto the corporation. We assess the originsand the intellectual foundations of the 'shareholder versus stakeholder' debate. We askwhether and how 'stakeholding' might be a morelogical or rational system, a fairer or moredemocratic system, and one that provides betterperformative outcomes. Each of these claims isassessed in respect to the micro firmperspective and the macro economy-wideperspective.One of the most difficult and neglected areasin the stakeholding debate concerns thepracticalities of its implementation. The papertackles this issue directly, at both thedomestic and the international level. We asknot only how stakeholding might be sensiblyintroduces within a national context but alsowhat it means to discuss stakeholding inrespect to transnational enterprises.  相似文献

Most public health risk assessments assume and combine a series of average, conservative, and worst-case values to derive a conservative point estimate of risk. This procedure has major limitations. This paper demonstrates a new methodology for extended uncertainty analyses in public health risk assessments using Monte Carlo techniques. The extended method begins as do some conventional methods--with the preparation of a spreadsheet to estimate exposure and risk. This method, however, continues by modeling key inputs as random variables described by probability density functions (PDFs). Overall, the technique provides a quantitative way to estimate the probability distributions for exposure and health risks within the validity of the model used. As an example, this paper presents a simplified case study for children playing in soils contaminated with benzene and benzo(a)pyrene (BaP).  相似文献

Millions of Medicare-age Americans are drug dependent, not because of addiction but because of common chronic health problems such as diabetes, heart failure, high blood pressure, and arthritis. Seniors are up in arms because drug company control of distribution and pricing of pharmaceuticals is eating away hard-earned nest eggs. Who cares? Where's the justice?  相似文献
