Many families did not leave welfare of their own accord but instead were forced off, sanctioned, for failure to conform to new, strict requirements (Bloom & Winstead, 2002). Studies of leavers indicate that many of these leavers are among the families that do not receive needed health insurance, food stamps, and child care assistance for which they remain eligible (Loprest, 2001; Zedlewski & Gruber, 2001). Sanctioned families are less likely to do well after leaving welfare compared to other leavers (Goldberg & Schott, 2000). As part of TANF reauthorization, Congress should prohibit states from sanctioning if they have not met certain requirements: conducted an assessment, made accommodations for people with physical/mental impairments or other barriers, and instituted strong pre-sanction and post-sanction procedures.  相似文献

One of the standard problems in statistics consists of determining the relationship between a response variable and a single predictor variable through a regression function. Background scientific knowledge is often available that suggests that the regression function should have a certain shape (e.g. monotonically increasing or concave) but not necessarily a specific parametric form. Bernstein polynomials have been used to impose certain shape restrictions on regression functions. The Bernstein polynomials are known to provide a smooth estimate over equidistant knots. Bernstein polynomials are used in this paper due to their ease of implementation, continuous differentiability, and theoretical properties. In this work, we demonstrate a connection between the monotonic regression problem and the variable selection problem in the linear model. We develop a Bayesian procedure for fitting the monotonic regression model by adapting currently available variable selection procedures. We demonstrate the effectiveness of our method through simulations and the analysis of real data.  相似文献

The author reviews the beginnings of child welfare research in the United States with an emphasis on the contributions of several outstanding individuals as well as the conflict between hereditarian and reformist values and attitudes. Both hereditarian and reformist values and attitudes had tremendous influence on the development of child welfare research as well as the helping professions.  相似文献

Sports public relations always serves two masters—both corporatas and communitas. In this article, a close textual analysis of the National Collegiate Athletic Association's (NCAA's) Stay in Bounds community relations program reveals that the NCAA is both a defender of amateur, communitas values, and a participant in professionalized, corporatas organizational rhetoric. This article offers a typology of the specific competing commitments of communitas and corporatas in sports rhetoric and argues that all sports rhetoric, from little league to big league, must negotiate with publics a balance between these extremes.  相似文献

A Perspective on Dioxin Emissions from Municipal Solid Waste Incinerators   总被引:2,自引:0,他引:2  
This paper discusses the following key issues concerning human exposure to dioxins and furans emitted from typical, modern MSW incinerators: (1) Are MSW incinerators the major source of PCDD/PCDF input into the environment? (2) Are environmental concentrations around MSW incinerators substantially elevated relative to background levels? And (3) are MSW incinerators the major source of human exposure to PCDDs and PCDFs? Current scientific evidence indicates that (1) combustion sources in general (including steel mills, copper smelting plants, motor vehicles, pulp and paper mills, and MSW incinerators) are major sources of PCDD/PCDF input in the environment; (2) environmental concentrations of PCDDs and PCDFs around operating MSW incinerators are not substantially elevated; and (3) 99% of human exposure to PCDDs and PCDFs is from background contamination, even for individuals living near a modern MSW incinerator.  相似文献

The provision of civil liberties to LGBT persons has become part of a global movement in societies across the world. In Brazil, a recent judicial ruling for the first time established the right for homosexual couples to enter into civil unions, despite the presence of widespread disapproval of homosexuality among the population and opposition from prominent religious groups. Picking up on this issue, the following study examines whether religion may factor into the attitudes Brazilians hold toward homosexuality and same-sex civil unions. Using data from the Brazilian Social Research Survey, we find that the most restrictive views toward homosexuality and the strongest opposition to same-sex civil unions are most prevalent among devoted followers of historical Protestant, Pentecostal, and Catholic faith traditions, whereas adherents of Afro-Brazilian and spiritist religions, as well as those with no religious commitment, are inclined to assume a more tolerant moral posture toward such issues. The findings point to religion as a potential influence in future public policy initiatives and social movements involving LGBT issues in Brazil.  相似文献

Hurricane Katrina’s effect on the population of the City of New Orleans provides a model of how severe weather events, which are likely to increase in frequency and strength as the climate warms, might affect other large coastal cities. Our research focuses on changes in the migration system—defined as the system of ties between Orleans Parish and all other U.S. counties—between the pre-disaster (1999–2004) and recovery (2007–2009) periods. Using Internal Revenue Service county-to-county migration flow data, we find that in the recovery period, Orleans Parish increased the number of migration ties with and received larger migration flows from nearby counties in the Gulf of Mexico coastal region, thereby spatially concentrating and intensifying the in-migration dimension of this predominantly urban system, while the out-migration dimension contracted and had smaller flows. We interpret these changes as the migration system relying on its strongest ties to nearby and less-damaged counties to generate recovery in-migration.  相似文献

Objectives. In this article we examine political advocacy by nonprofit organizations. Relatively little is known about the types of organizations that participate in advocacy, their characteristics, the issues for which they advocate, and the resources they devote to it. This is especially the case for nonprofits that operate at the state or local level. Methods. Using data from a large survey of Indiana nonprofit organizations, we use logistic and multinomial regression to determine which organizational characteristics relate to participation in varying levels of advocacy. Results. We find that the size of the organization, its access to information and communication technology, its charitable status, and, in some cases, the field of activity in which it operates all help predict nonprofit advocacy. The age of the organization, its reliance on government funding (except when substantial), and its proximity to the state's major economic and political center do not generally help differentiate nonprofits that advocate from those that do not. Conclusions. Our findings suggest that most nonprofits are ambivalent about advocacy. Some do no advocacy at all; many participate in some form of it although it does not constitute their primary purpose or mission; and only a small minority devotes considerable resources to it. However, these patterns differ systematically by type of nonprofit.  相似文献
