This study investigated the impact of the abolition of the tender years doctrine on custody decisions in divorce cases. This doctrine supported the presumption that the mother is the more suitable parent for young children. In March of 1981, the Supreme Court of the State of Alabama found this doctrine to be unconstitutional. To assess the hypothesis that this ruling had a significant effect on custodyrelated decisions, a sample of court records for divorce cases in an Alabama county was examined as representative of the state on a number of key variables. Overall, no significant differences were found on indicator variables for the comparisons before and after the ruling. There was neither an increase in custody grants to fathers nor an increase in custody requests by fathers.  相似文献

Certain Biblical passages if interpreted literally can be understood as advocating the use of corporal punishment in disciplining children. The purpose of this research was to determine if persons affiliated with religious denominations which emphasized a literal belief in the Bible would demonstrate less appropriate attitudes with regard to discipline than their counterparts who were affiliated with religious denominations which do not subscribe to a literal interpretation of the Bible. The sample consisted of 881 persons who were members of denominations classified as literal or nonliteral believers. Statistically significant differences were noted on the Physical Punishment Scale of the Adult Adolescent Parenting Inventory with persons, regardless of gender or their level of education, who were members of churches subscribing to a literal belief in the Bible preferring the use of corporal punishment over alternate methods of discipline as compared to their nonliteral counterparts.  相似文献

A risk marker analysis of assaulted wives   总被引:1,自引:0,他引:1  
In the wife assault literature, a number of risk markers have been identified. Using the data of the female respondents to the National Family Violence Survey (n = 699), a multivariate analysis was performed to examine which risk factors best differentiated between women involved in nonviolent relationships, verbally aggressive relationships, relationships exhibiting minor physical aggression and severely violent relationships. High levels of marital conflict and lower socioeconomic status emerged as the primary predictors of an increased likelihood of wife assault. Research implications are discussed.  相似文献

This paper examines the process by which R&D results funded by the Office of Conservation and Renewable Energy (CE) of the US Department of Energy (DOE) have generated commercial applications. It looks at examples of technology-transfer procedures and activitees across three of CE's component offices that correspond to the major energy end-use sectors: transportation, buildings, and industry. On the surface, the conservation programs would appear to have little strategic consistency and, therefore, lack the clear leadership many seek in a technology-transfer program. However, as an alternative to strategic consistency, one may tailor the technology-transfer approach of each program to its unique circumstances. This paper presents case studies of such tailoring, in which the diversity of approaches mirrors the complexity of the energy end-use markets and the private-public interests that must be negotiated to successfully commercialize energy-saving innovations. The paper discusses the lessons learned about the conditions requiring adaptive design and the structures and practices that have been proven effective.  相似文献
