Little literature has been developed to describe the process of transferring a corporation's technology between international units of that company for ultimate transfer to their external customers (Kimberly 1981 and Leonard-Barton and Sinha 1993). This paper addresses the issues at Air Products and Chemicals, Inc. involved in the transfer of applications technology. Technology is transferred from the unit of the corporation which develops the technology to international affiliates and subsidiaries. The ultimate goal is the support of product sales to the external industrial customer. A strategy for this type of organization is described which is supported by references to theoretical constructs in the literature and empirical observations from the organization itself.  相似文献

Recent British work has focused attention on preventing repeat victimization as part of an overall crime prevention strategy. Because domestic violence victims are among those most likely to suffer multiple victimizations, they are logical candidates for programs targeted at reducing repeat victimization.
This article reports on a joint law enforcement-social services approach to reduce the incidence of repeat domestic violence. The research design randomly assigned households reporting domestic incidents within two public housing police service areas in New York to receive or not receive a follow-up to the initial patrol response. (The follow-up visit was conducted by a police officer and a social worker.) In addition, housing projects in the same area were randomly assigned to receive or not receive public education about domestic violence.
Neither treatment produced a reduction in violence. However, households in projects that had received public education and households that received the follow-up visits were both more likely to report new violence to the police than households that did not receive the treatments. Moreover, the effect of the follow-up visit was most pronounced among households with more serious histories of violence. The results suggest that the interventions increased citizens' confidence in the ability of the police to handle domestic situations.  相似文献

This paper concerning the last 87 malpractice cases referred to the Department of Psychiatry and Law, Menninger Clinic, includes 57 suits against mental health practitioners and/or institutions, and 30 nonpsychiatric suits against general hospitals, surgeons, obstetricians, etc. A patient was available for interview in only 12 percent of the psychiatric cases; in 88 percent we reviewed medical records and consulted with attorneys. In the psychiatric cases the crucial question was whether a generally accepted standard of care was breached. The inherent problems of applying appropriate criteria to standards of care by practitioners and institutions are discussed. In half the psychiatric cases we found no significant deviation from acceptable clinical performance; in half we concluded that negligent practice had occurred. We did see a litigant for evaluation in 90 percent of the nonpsychiatric cases. The main issue involving them concerned harm or disability related to presumed negligence by medical personnel. How we evaluate such cases and apply disability criteria is discussed.  相似文献

All records from the Danish Medicolegal Council concerning drivers suspected for drug influences were examined for the 5 year period 1981-1985. 461 records were included, 62 women and 399 men. In 250 cases drugs from more than one of ten groups had been taken thus making 786 combinations of drug/driving. The major drug group was benzodiazepines, accounting for 65% of all drug intake. Opioids also contributed substantially, found in 38% of the cases. A traffic accident had occurred in 180 (39%) of the records. Drivers who had been taking antidepressives were involved in an accident in 67%, significantly above the mean. For benzodiazepines, the corresponding percentage was 43%, while for opioids it was only 23%, significantly below the mean. This striking difference has been demonstrated in most of the studies concerning drugs in traffic. It may support the hypothesis that opioids do not necessarily make driving dangerous, as do antidepressives, barbiturates and especially benzodiazepines.  相似文献

We derive a simple inequality for the probability of observing a given DNA profile when assuming a fixed number of unknown persons have contributed to the mixed stain. We then show how this inequality can be used to obtain an upper bound for the number of unknown contributors needed to be considered.  相似文献

行政立法程序既应追求行政行为的效率,又应追求立法行为的民主。在民主与效率之间,行政立法程序应以民主为更高的价值追求。针对我国目前的法律、法规及行政立法的现状,在行政立法准备制定阶段应建立更为民主的制度,但同时也不能忽略行政立法程序的效率。  相似文献
