The Rehabilitation Engineering Research Center on Technology Transfer (T2RERC) hosted a “State of the Science” conference in November, 2001. The conference reviewed technology transfer work within the field of assistive technology, and summarized related work in public, private and academic sectors. Invited speakers prepared papers on various topics concerning technology transfer, and related their findings to the field of assistive technology during the ensuing discussion sessions. This paper provides an overview of the material presented by the participants, and explores the implications of their findings for one particular field of application—assistive technology for people with disabilities.  相似文献

This article explores the reasons for the introduction of anticorruption agencies of a specific type in Eastern Europe. It is argued that one of the important functions of these agencies—which are stronger on information gathering, coordination and strategy rather than on investigation of concrete cases—is to give to the government some leverage over the anticorruption discourse. Presenting the anticorruption commissions and agencies as (discourse-controlling) instruments gives an answer to the troubling question why governing parties are at all interested in the introduction of such bodies. Apart from instrumentalization in political discourse, anticorruption bodies in Eastern Europe have had other effects as well. As shown in the Baltic case, institutional engineering provides for a brief window of opportunity during which political forces committed to integrity could gain the upper hand. The problem in Eastern Europe, however, is not the lack of such windows of opportunities—it is more the lack of really committed political forces capable of continuous and consistent anticorruption effort.  相似文献

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
