This article examines the effect of federal housing and public assistance programs on the housing quality of different Latino
households. The research tests models of crowding and housing tenure and structure for Latino households. The data for this
research are from the 1990 Latino National Political Survey-Panel Study of Income Dynamics (LNPS-PSID). Findings reveal that
housing and public assistance programs do help alleviate crowding among the Latino population, but they do not help Latino
households achieve ownership of a single-family home. All the demographic variables in the model contribute to the explanation
of crowding, and a majority also significantly explain housing tenure and structure. Significant differences are found among
Latino subgroups in the explanatory variables for crowding, tenure, and structure.

The purpose of this paper is to describe the various process deviations which can cause a runaway reaction to occur, and to discuss the experimental information necessary for risk assessment, the choice of a safe process, and the mitigation of the consequences of the runaway reaction. Ten typical hazardous process situations have been identified, considering various modes of initiation, homogeneous and heterogeneous, Arrhenius, and autocatalytic reactions. Each possible hazardous process deviation is illustrated by examples from the process industry and/or relevant experimental information obtained from laboratory experiments. 相似文献

This study examines the friendship patterns of older adults living in rural and urban areas. The sample consisted of 132 urban adults and 126 rural adults, 65 years of age and older. Respondents were randomly selected and interviewed in their own homes. While both groups were involved in joint social activities and helping behaviors with their friends, there was a distinction in the type of involvement according to geographical location.Karen Roberto is Assistant Professor and Coordinator of the Gerontology Program at the University of Northern Colorado.

The participants in this study were adult males (N = 111) who were accused of various sexual crimes against children 16 years of age or younger, and who were evaluated at a state forensic facility in a large Midwestern state. This study examined the relationship of Psychopathy Checklist-Revised (PCL-R) scores to type of child sexual offender (same sex extrafamilial, opposite sex extrafamilial, and incest offenders), the presence of violence during the most recent child sexual offense, and criminal versatility. Results indicated that those sexual offenders who employed physical violence against the children they abused were significantly more psychopathic than those who did not. No significant differences were found between types of child sexual offenders or with general criminal versatility. 相似文献
