This study examined the relationship among cognitive functioning, social support networks, and risk for child abuse in a sample of 92 mothers of developmentally disabled children. Mothers found to be at highest risk for child abuse potential tended to score low on cognitive skills, social support networks, and life satisfaction. Beck Depression Inventory scores were found to explain 57% of the variance in the Child Abuse Potential Scores. Single mothers differed significantly from married mothers on child abuse potential, relationship satisfaction, community involvement, and loneliness. The authors discuss implications of the study and the need for future research with families of handicapped children.  相似文献

In this article, we develop an empirical model of an agro-pastoral system subject to high climatic risk in order to test the impact of rainfall variability on livestock densities, land allocation patterns and herd mobility observed at the community level. Also, because grazing land is a common-pool resource, we determine the impact of cooperation on these decision variables. To capture different abilities of communities to cooperate in managing these externalities, we construct indices comprised of factors considered to affect the costliness of achieving successful cooperation. We then test hypotheses regarding the impact of rainfall variability and cooperation, using data collected in a semi-arid region of Niger. Results indicate that rainfall variability initially leads to higher densities, but the impact becomes negative as variability increases still further. This result indicates that the benefits of accumulating large herds in variable environments are eventually offset by the increasing probability of large losses. Mobility in the current period is strongly related to current rainfall, and is also positively related to long-term rainfall variability. Communities with characteristics hypothesised to favour cooperation have lower stock densities and greater herd mobility. Neither cooperation nor rainfall variability has a significant impact on the proportion of land allocated to crops or common pastures.  相似文献

The Inventory of Legal Knowledge (ILK) is an instrument designed to detect feigning of competency-specific knowledge deficits. Available studies have suggested the ILK may require modification of its cut score to more accurately classify those who are feigning. In this study, the ILK’s concurrent validity and cut scores were tested using 100 college students in a simulation design. Students were randomly assigned to fake (n = 50) or honest (n = 50) groups. Those assigned to the faking group had significantly lower ILK scores than individuals responding honestly with a large effect size between the groups. Despite some promising results, utility estimates indicated an unacceptable level of false positives using the recommended cut score. Tentative recommendations are made in order to improve the efficacy of the ILK in detecting feigning legal knowledge.  相似文献

Public discourse around changes introduced as part of a drive to tackle spending on welfare, reflect a less than tolerant attitude towards welfare generally, but more specifically towards parents who require state involvement to care safely for their children. The introduction of a deadline of 26 weeks for the completion of care proceedings, together with a clear steer to resolve disputes wherever possible prior to making an application to court has introduced further instrumental approaches to working with parents. In this paper we explore practitioner experiences and understandings of working within the new legislative frameworks and consider the dominant cultural narratives they are working within. However, in some cases professionals felt able to challenge the economic narrative of the pre-proceedings protocol, and they experienced the legal and policy changes as an opportunity to engage in a helping alliance with families with the provision of support that otherwise they would not have been able to offer.  相似文献

Over the past twenty years, several empirical studies have examined the consequences of job satisfaction among correctional staff. When looking at worker behavior in other disciplines, though, it is commonplace to include both job satisfaction and organizational commitment. However, very few studies about correctional staff behavior include both concepts. This paper discusses job satisfaction and organizational commitment, and addresses the link between these concepts as it relates to correctional staff attitudes and behaviors. Further, a discussion of measurement issues and recommendations for future research is presented. This is a revision of papers presented at the 1998 American Society of Criminology annual meeting in Washington, D.C. The authors would like to thank the anonymous reviewers for their comments and suggestions.  相似文献

Previous research has found that presidents, in general, have the power to influence congress in the passage of federal crime control policy. What has not been fully explored is whether presidential supported bills are more likely to influence congress to pass federal crime control bills. Therefore, this study draws upon the theory that presidents influence congress to test the hypothesis that president supported legislation on crime will achieve greater success in congress than non-supported bills. Analysis of legislative, presidential and congressional data from 1946 through 1996 suggests support for the theory that presidential supported bills are 2.8 times more likely (or 185% more likely) to become law.  相似文献
