The paper reports on the methodological features and early application of the model underlying the DYNAMICO Projects, which has been developed at the United Nations Secretariat to study the interaction between trade and development. In order to investigate alternative development strategies, scenarios are calculated year by year for the global economy and the ten regions covered in the model.Each year is represented by a block-angular linear programming problem, where the systemwide (or coupling) constraints represent the world market clearance conditions for nine tradable commodities. Each subblock of relations represents the economy of a given region. The Dantzig-Wolfe decomposition method is used to solve the system.Section 2 reviews the specifications of a typical regional subproblem. Each regional subproblem contains the following material balances; labor, land, and capital requirements; investment functions; the most important macroeconomic definitions; and several other restrictions to simulate policy constraints concerning both domestic and external economic activity.Decomposition methods may, in general, be viewed as resource-allocation procedures valuable to capture some of the essential features of decentralized decision-making. In the literature, two classes of such resource-allocation procedures have been proposed: primal (relying on quantity signals), and dual (relying on prices). Section 3 discusses some of the theory underlying the Dantzig-Wolfe method, which is a price-directive one.Section 4 describes in detail the particular solution method implemented in the model. At first, in a prelink phase, each regional subproblem is solved a number of times on the basis of  相似文献

The rise in paid care workers has not, until very recently, included carers specifically trained to provide domiciliary postnatal care. In 2002 a new occupation of domiciliary postnatal carers was introduced in the catchment area of a large metropolitan hospital in Adelaide, South Australia. The carers work with professional midwives to provide home based postnatal support to women discharged early from hospital following childbirth. Carers were trained in a short, six month program, and were recruited from long term unemployed young women from the same geographically disadvantaged catchment area as the hospital. In this paper, findings from the evaluation of the program are described and analysed. These include its implications for the postnatal care workers themselves and for the professionals involved in training and working with them. In addition, the implications for birthing women of a program using young, minimally trained carers are considered. Finally, the more general lessons for the training and ‘insertion’ of paid carers into domiciliary work with professionals are reflected on.  相似文献

Children and their parents who become homeless constitute a group of families with a complex range of social care and health needs, including mental health difficulties. In response to this, a local authority housing department established a family support team (FST) that provides assessment and detection of a range of problems, support to parents and children, parenting interventions for child behavioural problems, liaison with other agencies, and referral to specialist services when appropriate. The aim of this study was to establish the perceptions of parents and staff on their experience of the service, and ways of improving it in the future. The study adopted a developmental evaluation approach and used multiple methods, including in‐depth interviews with families; diaries; reflective activities; participatory learning and action; and observation of the FST. The study mapped the innovative service and captured the range of skills in the team and the complexity of agencies the team interacted with. It also identified areas for further development in terms of the mental health needs of children and parents who have become homeless.  相似文献

We administered the 18‐item Recalled Childhood Gender Questionnaire‐Revised (RCGQ‐R), female version, to 147 adult women with congenital adrenal hyperplasia (CAH) representing three different degrees of prenatal androgenization due to 21‐hydroxylase deficiency and to non‐CAH controls. A principal components analysis generated 3 components accounting for 46%, 9%, and 6% of the variance, respectively. Corresponding unit‐weighted scales (high scores = feminine) were labeled Gender Role (13 items; Cronbach α = .91), Physical Activity (3 items; a = .64), and Cross‐Gender Desire (2 items; α = .47). Discriminant validity was demonstrated in terms of highly significant comparisons across the 4 groups. We concluded that the first 2 RCGQ‐R scales show good psychometric qualities, but that the third scale needs to be evaluated further in a sample that includes women with gender identity disorder.  相似文献

Body image concerns typically affect women more so than men, but there is reason to believe that this pattern may depend on sexual orientation. The present study examined differences in levels of body satisfaction among men and women who identified as heterosexual, plurisexual (bisexual and pansexual), gay, and lesbian, using data from a large-scale national probability sample from New Zealand (N = 17,005). As expected, heterosexual men reported higher body satisfaction than heterosexual women. Gay and plurisexual men reported lower body satisfaction than heterosexual men. Gay men also reported lower body satisfaction than lesbian women, and did not differ significantly from heterosexual and plurisexual women. Ratings of heterosexual, plurisexual, and lesbian women’s body satisfaction did not differ significantly. Results held when adjusting for a range of demographic covariates (including age and BMI), and highlight the importance of examining the psychological and health outcomes associated with poor body image among gay men. These findings emphasize the relevance of sexual orientation in understanding men’s body image-related issues.  相似文献

Abstract

This essay provides a comprehensive overview of William J. Goode’s contribution to the study of global family and social change. I begin by describing Goode’s theoretical perspectives and outlining his theses dating back to the 1960s. I then provide an assessment of where and why some of his predictions proved wrong and elaborate on what we have learnt on changes in families at the global level over the past half century. Lastly, I speculate on how Goode would rethink his arguments nowadays in light of fifty years of new evidence and scholarly developments – both theoretical and methodological. In so doing, I highlight shortcomings of current approaches and outline directions for future family research and theorizing.  相似文献

Models of marriage and family therapy (MFT) typically reflect Western values and norms, and although cultural adaptations are made, many models/frameworks continue to be inappropriate or inadequate for use with non‐Western cultures. Worldwide, therapists are examining ways of using MFT models in a culturally sensitive manner, especially when working with clients who are seen as having minority status or perceived as “other” by the dominant group. This essay suggests the use of responsive evaluation as a theoretically consistent methodology for creating and evaluating culturally responsive therapies. This approach rigorously evaluates each unique client/therapist context, culture, power, needs, and beliefs. We describe responsive evaluation and discuss how each component addresses the research needs of examining culturally responsive family therapies. A case illustration is offered delineating the process of conducting culturally responsive therapy with a Cambodian sample using solution‐focused and narrative therapy.  相似文献
