In recent years, legislators in all fifty states have given grandparents rights to petition for visitation privileges with grandchildren that can be enforced over parental objections. Grandparent visitation rights reflect an effort to protect meaningful relationships children enjoy with nonparental caregivers, enlist the assistance of extended family when the child's nuclear family is disrupted, and defend the interests of grandparents themselves. This psycholegal analysis explores the direct and indirect consequences of grandparent visitation statutes for family functioning. Statutory provisions are summarized, and the effects of these statutes are evaluated in light of what is known about the role of grandparents in child development, how courts evaluate children's "best interests" in grandparent visitation disputes, and how these statutes can alter family functioning in informal ways. The authors conclude that there are risks as well as benefits to children and families in grandparent visitation statutes, and suggest directions for procedural and statutory reform. 相似文献

The remains of an unidentified female neonate were discovered in a field in central Missouri. Examination revealed bilateral absence of the parietal bones. A search of the literature describing similar defects suggests that the present case represents a unique condition, described here for the first time. 相似文献

This article focuses on media reportage of offensive juveniles, past and present, to elicit lessons that the twenty-first
century can learn from the Victorian past in terms of diversionary responses. How to prevent vulnerable juveniles sliding
into dangerous criminality is a continuing preoccupation: the issue explored in this article relates to the creation of the
identity of the criminal juvenile. In utilising the concept of semi-criminality to label certain types of juvenile anti-social
behaviour the Victorians avoided actual criminalisation of socially offensive but, in legal terms, minor behaviours. The reasons
for and negative consequences of the abandonment of this concept by the modern age are explored, including the reconceptualisation
of where responsibility for juvenile offending lies in the modern era. 相似文献
