Evaluation researchers have been broadening the traditional client input--"black box" treatment--client outcome paradigm that has guided many evaluations of mental health, substance abuse treatment, and other intervention programs. The points of expansion are in the areas of treatment implementation and treatment processes, as well as "extratreatment" influences on treatment selection, duration, and, especially, outcome. This review illustrates the application of environmental assessment procedures--particularly social climate measures--in four aspects of evaluation research suggested by the more comprehensive model: (a) evaluating treatment implementation; (b) exploring treatment processes; (c) identifying extratreatment influences on client posttreatment functioning; and (d) operationalizing outcome variables. Conceptual and methodological issues raised by these applications are discussed, and the benefits to be derived from an expanded model of evaluation research--especially the greater potential for program improvement--are considered.  相似文献

Children in Africa face harsh risks and are often subjected to hostile environments that severely limit their emotional, mental, physical, and social growth and development. That, in turn, significantly limits their prospects for childhood survival, increases their chances of having to enter into employment voluntarily or forcibly, and makes them susceptible to poverty. This paper examines and analyzes the plight of Africa's children in the context of the risks they face with respect to their mortality, their socio-economic security, and their engagement in economic activities. The trends and contributory factors are discussed and an analytical assessment is offered with policy implications for mitigating the consequences of child mortality, poverty, and labor on the African continent.  相似文献

Long‐term and short‐term (seasonal) migrations from Caribbean countries have been strategies for enhancing the livelihoods and assets of individuals and families for many decades. The greatest challenges to food security are felt by the populations below the poverty level, most of whom are rural dwellers. Taking two Caribbean countries – Jamaica, and St. Vincent and the Grenadines, this article assesses whether in rural, characteristically small‐farming areas, the financial and social remittances resulting from migration are used to improve food security, through either supporting agricultural production or providing money to purchase food. The findings show the contrast between Jamaica and St. Vincent. Whereas migration generally benefits small‐scale farming and domestic food production, increasing food accessibility in Jamaica, migration has been variously used by the rural poor in St. Vincent to replace farming. Food security in St. Vincent is heavily dependent on purchasing food and, in this regard, migrant remittances play an important role.  相似文献

We apply criminological theories of social control to explore the relationships among adolescent pregnancy, pregnancy resolution, and juvenile delinquency. While most ever-pregnant girls have especially high rates of delinquent behavior, adolescent mothers exhibit delinquency levels no higher than those of their never-pregnant peers. Unlike adolescent females who end their pregnancies through abortion, those who keep their babies experience a dramatic reduction in both smoking and marijuana use. Our results suggest that among adolescent girls, the birth of a child has a strong trajectory-modifying effect. It serves as a mechanisms of social control and substantially reduces the likelihood of delinquent behavior.  相似文献

We exploited an exogenous health shock—namely, the birth of a child with a severe health condition—to investigate the effect of a life shock on homelessness in large cities in the United States as well as the interactive effects of the shock with housing market characteristics. We considered a traditional measure of homelessness, two measures of housing instability thought to be precursors to homelessness, and a combined measure that approximates the broadened conceptualization of homelessness under the 2009 Homeless Emergency Assistance and Rapid Transition to Housing Act (2010). We found that the shock substantially increases the likelihood of family homelessness, particularly in cities with high housing costs. The findings are consistent with the economic theory of homelessness, which posits that homelessness results from a conjunction of adverse circumstances in which housing markets and individual characteristics collide.  相似文献

In late modernity there has been a massive growth in ‘new’ surveillance devices situated within schools. This paper explores the reasons behind this proliferation, considering the role of key protagonists and the promises made regarding these technologies. It is suggested that there is strong connection between notions of neoliberal governmentality (Foucault, 2008 ; Gane, 2012 ) and arguments relating to increased security, improved efficiency, the desirability of techno‐surveillance devices and desensitization to pervasive monitoring. In particular, it is maintained that the devolution of state power, the marketization of education, increased responsibilization and the nature of observation in the viewer society all help to explain the emergence of ‘surveillance schools’. It is concluded that failure to recognize these new dynamics may result in schools quietly, subtly becoming experimental labs and then junkyards for our surveillance futures.  相似文献

We used simulation modeling to assess potential climate change impacts on wildfire exposure in Italy and Corsica (France). Weather data were obtained from a regional climate model for the period 1981–2070 using the IPCC A1B emissions scenario. Wildfire simulations were performed with the minimum travel time fire spread algorithm using predicted fuel moisture, wind speed, and wind direction to simulate expected changes in weather for three climatic periods (1981–2010, 2011–2040, and 2041–2070). Overall, the wildfire simulations showed very slight changes in flame length, while other outputs such as burn probability and fire size increased significantly in the second future period (2041–2070), especially in the southern portion of the study area. The projected changes fuel moisture could result in a lengthening of the fire season for the entire study area. This work represents the first application in Europe of a methodology based on high resolution (250 m) landscape wildfire modeling to assess potential impacts of climate changes on wildfire exposure at a national scale. The findings can provide information and support in wildfire management planning and fire risk mitigation activities.  相似文献
