Bryson和Mowbray曾在1981年写文章批判政府盲目使用“社区”一词,并谈到关系着社区的循证政策如何在2005年成为一句空洞的政治口号。两篇文章都刊登在澳大利亚的社会问题期刊上。本文通过定性分析的方法搜集数据,考察南澳大利亚州某地方政府对“社区”的主观和现实意义作何理解,以评估其与社会政策制定者所使用的“社区”一词的吻合度。笔者认为,在2009年,社会政策制定者所使用的“社区”与围绕此主题展开的大量研究或者当前个体与家庭的情况缺乏共鸣,从而导致针对社区的社会政策其初衰与效果不相匹配。 相似文献

Foster carers' knowledge of caring for abused and neglected children is a largely under-researched area. We know very little about the nature of carers' knowledge in relation to caring for children who have been abused or neglected. This paper reports on an exploratory study which examined the knowledge of caring. Qualitative data were analysed based on in-depth interviews with 10 foster carers in Queensland, Australia. A range of knowledge was identified showing an interaction of both personalized and formal understandings in the caring response. Given the breadth of knowledge recognized from the analysis, this paper presents one dimension of their knowing: theory and abuse-indicated understandings. Participants' responses in these areas were at times sound, but many struggled to provide convincing and well-formed explanations of topics, such as attachment, harm and child development which may suggest that their understandings are not what they could be. Although further research is needed on a larger scale, this study does highlight the necessity to re-examine processes and strategies for carer knowledge support, so as to strengthen their understanding of these issues. 相似文献

A re-examination of the literature on the factors which influence residential segregation in American cities emphasizes the
complexity of the factors involved in generating patterns of separation in urban areas and the necessity of considering more
than any single factor in order to understand those patterns. In addition, recent on-going research on residential transition,
white flight, and the demographics of school attendance area change further emphasizes the declining importance of public
and overt private discrimination. Although private discrimination has not been eliminated from society, it cannot be relied
on as a total and unambiguous explanation for the patterns that we observe within metropolitan areas.
I would like to thank Tony Pascal for his advice and comments. 相似文献

Significant levels of separation between blacks and whites still exist in large American cities, and debate about the causes of that residential separation has been considerable. A balanced analysis of the factors that might explain residential segregation - economic status (affordability), social preferences, urban structure, and discrimination - suggests that no one factor can account for the patterns that have arisen in U.S. metropolitan areas. Empirical estimation of the impact of economic status suggests that 30–70 percent of racial separation is attributable to economic factors. However, economic factors do not act alone, but in association explanatory weight for present residential patterns. Survey evidence from both national and local studies shows that black households prefer neighborhoods that are half black and half white, while whites prefer neighborhoods ranging from 0 to 30 percent black.The debate about causes seems most polarized over the role of discrimination. Although comments in the literature often focus on the past use of racially restrictive covenants by state-regulated agencies and discriminatory acts by realtors and financial institutions, the documented individual cases of discrimination do not appear to be part of a massive collusion to deny housing opportunities to minorities. A review of the evidence from social science investigations demonstrates that there are multiple causes of racial residential separation in U.S. metropolitan areas.An earlier version of this paper was presented to the U.S. Commission on Civil Rights, Washington, D.C., November 12, 1985. 相似文献

This study examines two versions of how economic dependency has affected relative gender positioning in non-core nations' labor forces since the 1960s. A "new dependency" version asserts that multinational corporate investment in manufacturing has transformed the labor forces of such nations, permitting women unusual access to relatively high-paying, if ephemeral, light manufacturing positions. A "traditional trade dependency" version suggests that, despite the aforementioned transformation in some non-core nations, the dominant form of dependency in most remains traditional: they export primary goods in return for manufactured imports. This version claims that such structures not only deter women's entry into the formal labor force as a whole, but constrain those who do enter to relatively marginal agricultural positions. Panel analyses of data on non-core nations evaluates these versions and both receive considerable support. 相似文献

In this first part of the case study the authors introduced the background to the development of the planning models used by the Gulf Company. Both the Linear Programming model and the Sensitivity model are described, with discussion regarding the inter-relationship of these models and the discrete and mutual objectives behind their use. 相似文献

"This paper asserts a connection between economic dependency and divorce. It argues that, because dependency deprives women of equal access to the public sphere and because it confines them, through normative definition, to the private sphere, it reduces their likelihood of seeking divorce. The paper also argues, contrary to recent findings, that socioeconomic development should be linearly and positively associated with divorce. Data from 51 nations are examined and multiple regression analysis [suggests] considerable support for these arguments." 相似文献

Risks associated with toxicants in food are often controlled by exposure reduction. When exposure recommendations are developed for foods with both harmful and beneficial qualities, however, they must balance the associated risks and benefits to maximize public health. Although quantitative methods are commonly used to evaluate health risks, such methods have not been generally applied to evaluating the health benefits associated with environmental exposures. A quantitative method for risk-benefit analysis is presented that allows for consideration of diverse health endpoints that differ in their impact (i.e., duration and severity) using dose-response modeling weighted by quality-adjusted life years saved. To demonstrate the usefulness of this method, the risks and benefits of fish consumption are evaluated using a single health risk and health benefit endpoint. Benefits are defined as the decrease in myocardial infarction mortality resulting from fish consumption, and risks are defined as the increase in neurodevelopmental delay (i.e., talking) resulting from prenatal methylmercury exposure. Fish consumption rates are based on information from Washington State. Using the proposed framework, the net health impact of eating fish is estimated in either a whole population or a population consisting of women of childbearing age and their children. It is demonstrated that across a range of fish methylmercury concentrations (0-1 ppm) and intake levels (0-25 g/day), individuals would have to weight the neurodevelopmental effects 6 times more (in the whole population) or 250 times less (among women of child-bearing age and their children) than the myocardial infarction benefits in order to be ambivalent about whether or not to consume fish. These methods can be generalized to evaluate the merits of other public health and risk management programs that involve trade-offs between risks and benefits. 相似文献

We take a novel approach to analyzing hazardous materials transportation risk in this research. Previous studies analyzed this risk from an operations research (OR) or quantitative risk assessment (QRA) perspective by minimizing or calculating risk along a transport route. Further, even though the majority of incidents occur when containers are unloaded, the research has not focused on transportation-related activities, including container loading and unloading. In this work, we developed a decision model of a hazardous materials release during unloading using actual data and an exploratory data modeling approach. Previous studies have had a theoretical perspective in terms of identifying and advancing the key variables related to this risk, and there has not been a focus on probability and statistics-based approaches for doing this. Our decision model empirically identifies the critical variables using an exploratory methodology for a large, highly categorical database involving latent class analysis (LCA), loglinear modeling, and Bayesian networking. Our model identified the most influential variables and countermeasures for two consequences of a hazmat incident, dollar loss and release quantity , and is one of the first models to do this. The most influential variables were found to be related to the failure of the container. In addition to analyzing hazmat risk, our methodology can be used to develop data-driven models for strategic decision making in other domains involving risk. 相似文献
