There is little research on knowledge of the policy rules that could affect individuals, either in general or in evaluations of new programs. The lack of research is surprising, given that knowledge gaps could limit the effectiveness of reforms or lead to incorrect inferences regarding the effects of a policy change. In this article, we use survey data to examine the level and sources of welfare participants' policy knowledge in the context of a substantial change in child support and welfare policy in Wisconsin. We find very low levels of knowledge of child support policy rules. Multivariate analyses suggest that people tend to learn policy rules by experience; we find less consistent support for knowledge being primarily imparted through interactions with caseworkers. A difference‐in‐difference analysis suggests that if participants had been more knowledgeable, program impacts would have been larger. Implications of this research for policy implementation and policy evaluations are discussed. © 2007 by the Association for Public Policy Analysis and Management  相似文献

A 66-year-old man received a local infiltration of cortisone and xylocain in the left paravertebral region between the fifth and sixth cervical vertebrae. Respiratory failure occurred 2.5 h later with subsequent successful resuscitation. During the following 2 months of assisted ventilation up to the patients death, tetraplegia with concurrent full consciousness throughout was observed. Magnetic resonance imaging confirmed an ischaemic lesion of the upper anterior cervical myelon. The forensic autopsy revealed pneumonia as cause of death. Neuropathology confirmed anterior infarction at the C2/C3 level of the cervical myelon, with obstruction of the anterior spinal artery by an epithelialised fibrocartilaginous embolus. The autoptic findings suggest that this embolus stems from the site of previous analgetic infiltration, with accidental laceration of an intervertebral disc and subsequent transportation of discous material via injection canula into an artery.  相似文献

Fatal pulmonary cement embolism following percutaneous vertebroplasty (PVP)   总被引:9,自引:0,他引:9  
A case of fatal pulmonary embolism with acrylic cement occuring during a percutaneous vertebroplasty on account of a fracture of L1 is described. Autopsy confirmed the presence of large amounts of surgical cement in the paravertebral venous system and in the pulmonary arteries. This rare complication occurred because perivertebral venous cement migration was not recognized during vertebroplasty. To our knowledge, this is the first case of fatal pulmonary embolism caused by surgical cement following a percutaneous vertebroplasty.  相似文献

  • Business associations play a significant role in private–public interactions by aggregating company interests and relating these to political decision makers. Associations are particularly important for smaller firms, which generally do not have the resources to pursue political strategies independently. This paper discusses the question of what the motives are for small and medium‐sized firms to maintain their membership in national trade associations at a time when the European business environment is undergoing profound changes. Using the example of the Netherlands, it is argued that associational membership is determined foremost by political considerations. The implication of this conclusion is that national business associations continue to perform an important function in mediating business–government relations. Despite the internationalization of public decision making, these organizations remain important intermediaries for corporate public affairs.

This paper seeks to contribute to the growing literature on the entrepreneurial university by mapping knowledge exchange relationships of entrepreneurial faculty in a comprehensive manner and also capturing faculty attitudes towards measures taken by the university administration to promote entrepreneurship. We report on an exploratory study of Sussex University, a medium-sized, research-oriented university, which launched technology transfer activities in the mid-1990s. Our results show that, in spite of a comparatively late start, a considerable number of researchers engage in knowledge exchange processes with industry and other non-academic partners. We present evidence that suggests faculty in the social sciences and humanities as well as natural sciences and engineering maintain links to industrial partners, including multinational corporations. Furthermore, our observations indicate that schools differ in the way their faculty engage in university–industry collaborations. Further differences can be observed with respect to faculty attitudes towards technology transfer and awareness of the university’s respective codes of practice.
