In this article, the author reviews state supreme court applications of Troxel v. Granville , analyzing the impact of the decision on the courts' ongoing efforts to adjudicate visitation disputes between parents and grandparents. Set against a background of legislative recognition of grandparents' rights and judicial uncertainty regarding the appropriate role of nonparents in children's lives, Troxel reaffirmed the constitutional right of parents to direct their children's upbringing. The author argues that state supreme courts evaluating gradparent visitation statutes and seeking to enforce Troxel 's presumption in favor of parents should be more willing to strike down overly broad statutes. Such an approach would be a positive step toward addressing the excessive judicial discretion that the Troxel Court found so problematic, and would signal to state legislatures the need for statutes that both provide for the needs of children and protect parental rights.  相似文献

In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane.  相似文献

The present study explores the relationships between gender and imprisonment decisions in Minnesota before and after the introduction of sentencing guidelines. Results from a series of logistic regression models indicate that gender alone did not have a significant impact on the likelihood of imprisonment, but women with dependent children were significantly less likely to be imprisoned before sentencing guidelines and in the years subsequent to their implementation. The findings suggest that despite the introduction of sentencing reforms, court officials tend to return to issues of substantive justice, and they appear unable to shed their individual or organizational ideas of fairness in sentencing.  相似文献

Family courts and child welfare agencies across the country are charged with protecting the safety of our children. That mission has become more challenging with increasing federal legislation and decreasing funding. In Buffalo, N.Y., the Family Court and the Department of Social Services have teamed up to respond to this challenge. With minimal additional staffing and resources, they have led a collaboration of agencies and service providers to change the way business is done in child welfare. By engaging each other in an interagency system change effort, the amount of time children spend in foster care has been reduced. The collaboration has been able to accomplish in a relatively short time what no agency had previously been able to accomplish on its own. The beneficiaries have been the children and families of Erie County.  相似文献

In the wake of the 1990 amendments to the Clean Air Act, localities across the United States initiated public information campaigns both to raise awareness of threats to air quality and to change behavior related to air pollution by recommending specific behavioral changes in the campaign messages. These campaigns are designed to reduce the health hazards associated with poor air quality and to avoid federal sanctions resulting from the failure to meet air quality standards. As in many other communities across the country, a coalition of government agencies and businesses initiated a public information campaign in the Atlanta metropolitan region to reduce certain targeted behaviors, mainly driving. A two‐stage model used to analyze data from a rolling sample survey shows that the centerpiece of the information campaign—air quality alerts—was effective in raising awareness and reducing driving in a segment of the population. When the overall information campaign was moderated by employers' participation in programs to improve air quality, drivers significantly reduced the number of miles they drove and the number of trips they took by car on days when air quality alerts were sounded. Public information campaigns can be successful in increasing awareness, but changing well‐established behaviors, such as driving, is likely to require institutional mediation to provide social contexts that support the behavioral change, as well. © 2003 by the Association for Public Policy Analysis and Management.  相似文献
