Patterns and predictors of center-based early care and education (ECE) of children in foster care were examined. Participants included 192 pre-Kindergarten age children in foster care. Foster parents reported demographics, ECE and other service use. Foster care history data was abstracted from case files. High rates of attendance in ECE prior to Kindergarten, including Head Start, other center-based ECE, or both were found. Children who attended Head Start were younger when first placed in foster care. Children who attended other center-based ECE services were more likely to live with kinship foster parents and foster families with higher incomes. Latent class analysis of ECE quantity, quality, type, and duration revealed three patterns: part-time Head Start, part-time other ECE, and full-time mixed ECE. Child and foster family characteristics predicted these patterns, illustrating distinct groups with potential implications for the development of children in foster care. 相似文献

The purpose of this study is to explore the conflict between use and preservation in national parks policy as seen through the mission statement of the National Parks Service. The histories of the national parks were qualitatively coded in order to further explore this controversy, or what we have termed “mission rivalry”. 相似文献

Shannon Bybee J.D. 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》1988,4(4):301-308
An experienced lawyer for the gaming industry argues that the very appellation of compulsive gambling is misleading. Advocates of the medical model of compulsive gambling have created a strange new disease, where individuals are viewed as not responsible for their misdeeds but as solely responsible for their own cure. The fact that some individuals have problems because of gambling does not lead to the conclusion that casinos bear the ultimate legal or moral responsibility. More research and dialogue is needed; but so is the acceptance by problem gamblers and those who study and treat them that individuals have to take responsibility for their own conduct. 相似文献

This paper considers a general equilibrium model in which the distinction between uncertainty and risk is formalized by assuming agents have incomplete preferences over state‐contingent consumption bundles, as in Bewley (1986). Without completeness, individual decision making depends on a set of probability distributions over the state space. A bundle is preferred to another if and only if it has larger expected utility for all probabilities in this set. When preferences are complete this set is a singleton, and the model reduces to standard expected utility. In this setting, we characterize Pareto optima and equilibria, and show that the presence of uncertainty generates robust indeterminacies in equilibrium prices and allocations for any specification of initial endowments. We derive comparative statics results linking the degree of uncertainty with changes in equilibria. Despite the presence of robust indeterminacies, we show that equilibrium prices and allocations vary continuously with underlying fundamentals. Equilibria in a standard risk economy are thus robust to adding small degrees of uncertainty. Finally, we give conditions under which some assets are not traded due to uncertainty aversion. 相似文献

Why Has Safety Improved at Rail‐Highway Grade Crossings? 总被引:2,自引:0,他引:2
The number of collisions and fatalities at rail-highway intersections in the United States has declined significantly over the past 30 years, despite considerable increases in the volume of rail and highway traffic. This article disaggregates the improvement into its constituent causes. Negative binomial regressions are conducted on a pooled data set for 49 states from 1975 to 2001. The analysis concludes that about two-fifths of the decrease is due to factors such as reduced drunk driving and improved emergency medical response that have improved safety on all parts of the highway network. The installation of gates and/or flashing lights accounts for about a fifth of the reduction. The development in the 1970s and early 1980s of the Operation Lifesaver public education campaign, and the installation of additional lights on locomotives in the mid 1990s, each led to about a seventh of the reduction. Finally, about a tenth is due to closure of crossings resulting from line abandonments or consolidation of little-used crossings. 相似文献

Based on the example of Metropolitan Cork, this paper looks at strands of planning thinking as they apply to the city-region: economic and political arguments about the scale of a city; landscape arguments about identity and place; spatial arguments about urban form and environmentally grounded arguments about nature, ecology and the city. Bringing together the different theoretical contexts and disciplinary frameworks of these interrelated approaches and relating them both to the often contradictory principles of sustainable development and to the challenge of achieving appropriate systems of governance at this scale, it explores an initial argument for how holistic and mutually reinforcing approaches to the spatial resilience of a city region might re-emerge. 相似文献

The rapid spread of Saunders' thinking across the world has been facilitated by the Hospice Information service and library at St Christopher's Hospice which she helped to create and further enhanced by Help the Hospices. We have set this article in the context of the Web and other information systems as they are developing today. "Connecting people" and "collecting people's experiences" were terms often used by Cicely Saunders when she described the work of Hospice Information, a service that has in some measure contributed to the rapid spread of her thinking across the world and which is currently in close contact with palliative care workers in over 120 countries. Connecting--or networking--putting people and organizations in touch with each other for mutual benefit and collecting and disseminating people's experiences are central to our work as a U.K. and international resource on hospice and palliative care for professionals and the public. Add to these the crucial role of information provision and advocacy for patients, carers, and health professionals alike and we hope that you may begin to appreciate how our respective organizations have contributed to the spread of Cicely Saunders' vision. 相似文献

Previous research suggests many middle-class white women attempt to maintain femininity during labor and birth. There is also evidence that women who give birth outside the medical model may engage in more gender-deviant behaviors. The current study examines women’s accounts of gender performances during birth in the midwives model of care. Participants describe themselves engaging in a number of gender-deviant behaviors, without apology or overt remorse. However, participants also describe themselves engaging in activities during labor and birth that are traditionally considered feminine, including domestic tasks, care-giving and adhering to beauty norms; some defined childbirth itself as a feminine activity. Thus, participants are not simply adhering to or defying dominant notions of femininity, but are engaging in a complex set of gender behaviors. It is argued that study participants are prioritizing certain aspects of femininity—in particular, the “good mother”—over others. 相似文献

Much social science suggests that income inequality is a product of economic and demographic factors and recent work highlights the influence of Leftist politics in affluent Western democracies. But, prior research has neglected rightist politics. We examine the impact of cumulative right party power on three measures of income inequality in an unbalanced panel of 16 affluent Western democracies from 1969 to 2000. We find that cumulative right party power significantly increases inequality with effects comparable to other established causes. Left party power has less influence than the right on the Gini coefficient and the 90/50 ratio but a larger influence on the 90/10 ratio. Union density is insignificant after controlling for right party power. Right party power partly channels through and partly combines with government expenditures to affect inequality. Temporal interactions show that right parties became more influential after 1989 while left parties became less effective. Supplementary analyses suggest that a component of right party power's effects occurs through labor market inequality prior to taxes and transfers. Sensitivity analyses reveal that the results are robust to a wide variety of alternative specifications and operationalizations and do not depend on the inclusion of the U.S. in the sample. Our results inform debates about the sources of inequality and related sociological theories regarding class, politics, the state and the economy. 相似文献
