Hurricane Katrina exposed serious deficiencies in the social support safety net at the federal, state, and local level. This article explores the impacts of the disrupted safety net through participant observation and interviews with service providers and evacuees resettled in one southern city. Their stories illustrate how vulnerable low‐income groups struggle to cope with disaster within the context of inadequate larger support systems and the legacy of racism. The data also illustrate the limits of the local resources and response, given the years of retrenchment and underfunding and increasing dependence on nongovernmental sources of support. The authors explore some of the implications of this trend for evacuees' long‐term recovery and social work intervention.  相似文献

Social conditions influence sociological research muck more than they do other sciences. Consequently, beyond the common interests of the whole sociological community one can observe interests that are specific to social and cultural areas. It is to the interaction of general and specific sociological interests, and their relation to the possibility of constituting a ‘European’ sociology, that this paper is addressed. Its starting point is an analysis of the contributions at the XIIth World Congress of Sociology (Madrid, 1990). The relation of the proposed theme to the geographical area and gender of the conference participant was studied via the application of content analysis and the use of residual analysis. A profile of thematic preference was established for each variable category. The analysis shows that in Europe there is an evident preference for some questions, but despite this common trait, significant differences can be observed in terms of both the geographical area and gender variables.  相似文献

This paper first describes the basic characteristics of the Spanish system of retirement pensions, before addressing its major challenges in the future and the principal solutions proposed. For this purpose, many of the works on social security published in Spain over the past years have been reviewed to provide a recent overview of technical discussions on this subject. Finally, the main reforms undertaken by the government since 1995 are described in some detail and assessed.  相似文献

Research on family risk factors for addictive behaviors in young people has not paid a great deal of attention to parents' knowledge of their children's addictive behaviors and of the family risk factors that affect such behaviors. The aim of this work is to compare knowledge about these two aspects in two groups of parents that differ regarding their children's declared drug use. The research was carried out with a sample of 309 schoolchildren and their families, divided into two groups: one of 154 families with children defined as non-Drug Users and another of 155 families with children defined as Drug Users. The results show that parents with children who consume drugs tend to strongly underestimate their children's use. Moreover, they overestimate the control they exercise over them and appear to be more familiarized with the use of drugs, if we compare them with parents of non-Drug Users. It is suggested that these results may be relevant for the planning of strategies that increase motivation in families with drug-risk children to participate in prevention programs.  相似文献

This paper reports the preliminary findings of an exploratory investigation into information processing in a managerial context. The vehicle for testing several research objectives was a laboratory decision-making experiment in which subjects purchased information items and evaluated a set of organizational goals. The methodology included multidimensional statistical methods that hold promise for dealing with the complexity of problems in implementing managerial decision models. Within a specific information-decision scenario, the statistical evidence favorably supports the existence of individual differences in information perception and information selection, and the use of goal preference hierarchies as predictors of information preferences.  相似文献

Interval-grouped data are defined, in general, when the event of interest cannot be directly observed and it is only known to have been occurred within an interval. In this framework, a nonparametric kernel density estimator is proposed and studied. The approach is based on the classical Parzen–Rosenblatt estimator and on the generalisation of the binned kernel density estimator. The asymptotic bias and variance of the proposed estimator are derived under usual assumptions, and the effect of using non-equally spaced grouped data is analysed. Additionally, a plug-in bandwidth selector is proposed. Through a comprehensive simulation study, the behaviour of both the estimator and the plug-in bandwidth selector considering different scenarios of data grouping is shown. An application to real data confirms the simulation results, revealing the good performance of the estimator whenever data are not heavily grouped.  相似文献

A significant body of research on minority health shows that although Latino immigrants experience unexpectedly favorable outcomes in maternal and infant health, this advantage deteriorates with increased time of residence in the United States. This study evaluates the underlying assumptions of two competing hypotheses that explain this paradox. The first hypothesis attributes this deterioration to possible negative effects of acculturation and behavioral adjustments made by immigrants while living in the United States, and the second hypothesis attributes this deterioration to the mechanism of selective return migration. Hypothetical probabilistic models are simulated for assessing the relationship between duration and birth outcomes based on the assumptions of these two hypotheses. The results are compared with the empirical research on the maternal and infant health of first-generation, Mexican-origin immigrant women in the United States. The analysis provides evidence that a curvilinear pattern of duration and birth outcomes can be explained by the joint effects of both acculturation and selective return migration in which the former affects health status over the longer durations, and the latter affects health status at shorter durations.  相似文献

This article takes stock of a sample of interventions and programmes across different countries and regions supported by international organizations to foster the development of social enterprise. The primary objective of the article is to generate a compilation of such interventions and draw some lessons about their potential contribution to the growth and sustainability of the sector. The results indicate that international organizations’ support to social enterprise has focused primarily on the provision of financial resources, notably loans and grants. While programmes remain largely unassessed, the few available rigorous evaluations show that social enterprise has the potential to be a cost‐effective mechanism to deliver basic social services to the poor. The article proposes a set of policy recommendations directed primarily to international organizations and the public administration to improve and enhance their support to the sector.  相似文献
