Despite the important role they play in preventing homelessness, those who shelter people who can not afford housing of their own have been neglected by researchers. This study examines the characteristics of these low income informal shelter providers. While informal shelter providers were similar to a comparison group of low income households that did not shelter others, there were also significant differences between the two groups. Informal shelter providers were more much more likely to live in single family dwellings, they were more likely to be long-term residents of the community, they were more likely to have experienced homelessness themselves, and they devoted a disproportionate share of their incomes to housing. 相似文献

The purpose of this article is to acquaint the broader publicopinion research audience with what has been a salient issuewithin the community of scholars of religion. We address thequestion of how best to conceptualize and measure religiousidentities in research on contemporary American society. Weconsider the main approaches to the measurement of religiousidentification with regard to their backgrounds, their assumptionsabout the importance of understanding religious identities inhistorically relevant terms, and the practical considerationsof survey measurement. Using data from the General Social Survey,particularly recent innovative efforts to obtain informationon subjective association with particular religious traditionsand/or movements (e.g., Pentecostal, fundamentalist, evangelical,mainline, or liberal Protestant), we compare the two main approaches:the traditional "denominational" approach, where religious identitiesare assumed to be associated with religious denominations, andthe subjective approach, where religious identities are assumedto be captured by a set of "nondenominational" reference categorieslinked to particular historical religious traditions or socialmovements. We conclude that both approaches have substantialpredictive validity, and the most effective strategy for futureresearch may be one that uses a combination of approaches, ratherthan one that relies entirely on a single method of measurement. 相似文献

Older adults with severe self-neglect have multiple deficits in various social, functional and physical domains, and often live insqualor. These individuals often present with poor personal hygiene, domestic squalor and hoarding which results in a threat to their own health as well as personal and public safety. Severe self-neglect occurs along a continuum with older adults often having cognitive and affective disorders compared with younger individuals presenting with psychiatric illnesses. In cases of severe self-neglect with hoarding, evidence has shown this behavior occurs in diverse social strata and not among the wealthy and professionals alone as believed earlier. Due to the multiple conditions associated with severe self-neglect, this population will require an interdisciplinary, multidimensional approach to reduce morbidity and mortality rates including nursing home placement. Research on this group has been limited and is rarely described in the medical and nursing literature. Future research is needed to provide practitioners with effective screening instruments and interventions on cases of severe self-neglect. 相似文献

How racial barriers play in the experiences of Mexican Americans has been hotly debated. Some consider Mexican Americans similar to European Americans of a century ago that arrived in the United States with modest backgrounds but were eventually able to participate fully in society. In contrast, others argue that Mexican Americans have been racialized throughout U.S. history, and this limits their participation in society. The evidence of persistent educational disadvantages across generations and frequent reports of discrimination and stereotyping supports the racialization argument. In this paper, we explore the ways in which race plays a role in the lives of Mexican Americans by examining how education, racial characteristics, social interactions, relate to racial outcomes. We use the Mexican American Study Project, a unique data set based on a 1965 survey of Mexican Americans in Los Angeles and San Antonio combined with surveys of the same respondents and their adult children in 2000, thereby creating a longitudinal and intergenerational data set. First, we found that darker Mexican Americans, therefore appearing more stereotypically Mexican, report more experiences of discrimination. Second, darker men report much more discrimination than lighter men and than women overall. Third, more educated Mexican Americans experience more stereotyping and discrimination than their less educated counterparts, which is partly due to their greater contact with whites. Lastly, having greater contact with whites leads to experiencing more stereotyping and discrimination. Our results are indicative of the ways in which Mexican Americans are racialized in the United States. 相似文献

This paper suggests a Bayesian approach to the reconstruction of a 2 × 2 contingency table where some of the observations are only partially categorized and others are fully categorized. In contrast, most previous Bayesian and non-Bayesian analyses of the partially categorized data problem have been concerned with estimation of the parameters that generated the data. We show in an example that estimates may not be extremely sensitive to the weight placed on prior information relative to the sample data. 相似文献

The diagnostic tools examined in this article are applicable to regressions estimated with panel data or cross-sectional data drawn from a population with grouped structure. The diagnostic tools considered include (a) tests for the existence of group effects under both fixed and random effects models, (b) checks for outlying groups, and (c) specification tests for comparing the fixed and random effects models. A group-specific counterpart to the studentized residual is introduced. The methods are illustrated using a hedonic housing price regression. 相似文献

This article presents a Bayesian analysis of a multinomial probit model by building on previous work that specified priors on identified parameters. The main contribution of our article is to propose a prior on the covariance matrix of the latent utilities that permits elements of the inverse of the covariance matrix to be identically zero. This allows a parsimonious representation of the covariance matrix when such parsimony exists. The methodology is applied to both simulated and real data, and its ability to obtain more efficient estimators of the covariance matrix and regression coefficients is assessed using simulated data. 相似文献
