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

Using merged administrative data from welfare reform evaluations in three states, we estimate the effects of child care subsidy use on the length of time it takes for a welfare applicant to move into substantial employment. Findings show that the use of a child care subsidy during an unemployed or marginally employed spell of welfare receipt is associated with between a 0.6 and 1.7 quarter (or 11% to 34%) reduction in the time to substantial employment in two of the three state samples. The positive influence of subsidy use on transitions to substantial employment is strongest for those welfare applicants with the lowest earnings who are mixing welfare and work prior to subsidy receipt. 相似文献

Abstract: In a continuing quest to build and defend world markets for tobacco products, tobacco companies have long been involved in international cooperation and information‐sharing through their own international corporate networks, as well as through national and international industry trade associations. This is evidenced in tobacco industry corporate documents now freely available on the internet. In order to institute effective tobacco control policy, policy‐makers needed to become equally astute at sharing information across national boundaries and at considering the cross‐national implications of policy and legislation. The World Health Organization has been instrumental in developing the Framework Convention on Tobacco Control (FCTC), and Canada has played an important part in this effort. The FCTC contains both demand‐reduction provisions and supply‐side provisions intended to reduce tobacco use worldwide. As a signatory to the FCTC, Canada has pledged to adhere to these provisions, thereby providing Canadian public administrators with effective tools to reduce tobacco use and its associated health burden both nationally and internationally. Sommaire: En cherchant continuellement à développer et à défendre les marchés mondiaux pour les produits du tabac, les sociétés productrices de tabac sont impliquées depuis longtemps dans la coopération internationale et le partage d'informations par le biais de leurs propres réseaux de sociétés internationales et d'associations professionnelles nationales et internationales. C'est ce qui ressort des documents des sociétés productrices de tabac auxquels on peut accéder librement sur Internet. Afin d'instituer une politique efficace de contrôle du tabagisme, les décideurs politiques ont dù devenir astucieux quant au partage d'informations et à l'étude des répercussions transnationales des politiques et des lois. L'Organisation mondiale de la santé a fortement contribuéà l'élaboration de la Convention‐cadre sur la lutte contre le tabagisme (CCLCT), et le Canada a joué un rôle important sur ce plan. La CCLCT contient à la fois des dispositions relatives à la réduction de la demande et d'autres relatives à l'offre qui visent à réduire la consommation de tabac dans le monde entier. En tant que pays signataire de la CCLCT, le Canada s'est engagéà respecter ces dispositions, fournissant ainsi aux administrateurs publics canadiens des outils efficaces pour réduire la consommation de tabac et le fardeau sur la santé qui lui est associéà l'échelle nationale et internationale. 相似文献
