The tenth session of the World Food Council in Addis Ababa, Ethiopia, held on 11–15 June 1984, undertook an assessment of international activities in the decade since 1974 for meeting the World Food Conference objectives of improving the global food system and overcoming the blight of world hunger. One document prepared for the session looks specifically at the activities of the multilateral institutions since the 1974 conference, in terms of both resource and programme commitments. This article provides a summary of that WFC document. 相似文献

A primary goal of the 1996 Telecommunications Act isto encourage competition in long-distance telephonemarkets. Four years after passage of thislegislation, Bell Operating Companies (``BOCs') havebeen granted permission to offer long-distanceservices in only one state. The regulatory barrier toentry is justified on grounds that the BOCs have theability to discriminate against incumbentlong-distance carriers in the provision of essentialaccess services. We take this premise as given andquantify the critical level of discrimination requiredto offset the positive consumers' surplus gainsassociated with the enhanced competition resultingfrom BOC entry into long-distance markets. 相似文献

Based on an organizational adaptation framework, this study examines the influence of three environmental dimensions–munificence, stability, and complexity–on top management team turnover. In addition to investigating the direct influence of these environmental dimensions, indirect effects through firm performance and strategic change are also examined; the indirect effect of environmental complexity through demographic heterogeneity is also studied. Path analysis indicates that the direct effects of the three environmental dimensions predominate. Indirect effects were nonsignificant except for the effect of instability and munificence through strategic change. By expanding the team turnover context to include environmental and strategic dimensions, in addition to previously examined performance and heterogeneity factors, this study enhances our understanding of managerial turnover as a form of organizational adaptation. 相似文献

Labor costs for two versus one full-time nurse manager were compared. Results revealed reductions in nursing costs per patient day. These results suggest that innovative models may hold promise as organizations struggle to retain nurses and decrease costs. 相似文献

Insurance companies often test applicants for the presence of cocaine. Because a positive test may automatically preclude further consideration, such cases often never reach the medical director. The negative impact of cocaine use on insurability is reviewed. 相似文献

The United States is not the only country dealing with privacy of health information. In the absence of clear legislative direction, this paper focuses on the common privacy principles that underlie Canadian privacy legislation and recommends a plan of action. The objective is to give plan administrators and trustees sufficient transition time to develop and implement the appropriate privacy strategies, thereby minimizing both the potential burden of compliance and the potential risks of noncompliance. 相似文献
