In Morgentaler v. R., the Supreme Court of Canada struck down the abortion provisions in the Criminal Code. In a five to two split, a majority of the Supreme Court judges found that section 251 offended a pregnant woman's constitutionally protected right not to be deprived of her "life, liberty, and security of the person." Sheilah Martin reviews the three majority judgments and focuses on the decision written by Madame Justice Wilson. She believes that Madame Justice Wilson's opinion merits special attention in several regards: her conclusions on the constitutional rights of pregnant women; her recognition and validation of women's perspectives on abortion; and her approach to balancing women's interests in reproductive self-determination against the state's interest in regulating reproduction. Sheilah Martin concludes that this decision will reverberate far into the future. Even though it fails to establish clear guidelines concerning governmental power to control access to abortion, its principles outline the legal framework in which future litigation will occur, and it will limit and shape the terms of any ensuing political debate. In addition, Madame Justice Wilson's judgment holds great promise for those looking to the Court to promote the rights of women and other historically disadvantaged groups.  相似文献

The presence of smeared or unsmeared ink on the skin resulting from the writing process has been observed in a number of suicide victims who have left suicide notes. The authors report a case of a palmar "cutaneous ink sign" and discuss its forensic science import.  相似文献

This article is adapted from a paper presented at a conference that investigated the role of policy research in shaping public policy. The conference focused on how studies of economic and social forces and their relationship with public problems and programs affect the decisions of public policymakers. The author contends that research has the potential to inform policy-making in any of its five stages: problem identification, option development, passage of new laws or development of new procedures, implementation, and evaluation. She notes that different players in the policy-making process use research differently, from the senior government official who needs a quick review of what is known relating to a "hot" issue to the interest group lobbyist who wants access to raw data. The article concludes that research can best achieve its potential when (1) it anticipates policymakers' information needs, (2) it is disseminated in an accessible form understandable to nonresearchers, and (3) the policy analyst is willing to engage in the policy process as an advocate for efficiency.  相似文献

One of the important resources to any state, such as California, is the technology that is available from the many federally operated and/or funded laboratories within its borders. In this age of technology a state needs to take advantage of applications of modern technology and innovative exploitation of human and natural resources. This article illuminates the importance of the Federal Government research laboratories. Many examples are presented to support the argument that the Federal Government research laboratories can be and often are substantial contributors to the storehouse of technology that finds its way to the private sector and public sector. Several types of technology transfer are discussed, i.e. primary technology, secondary applications, mission related, technical assistance and cooperative. In addition the article discusses the structure and logic of the Federal Laboratory Consortium for Technology Transfer (FLC). The legislaltion that has helped to make the FLC effective is discussed. Included in the discussion are insights of how the FLC operates and how the private sector and public sector may use the FLC in order to locate process, product and service technology.  相似文献

System of cities dynamics in newly industrializing nations   总被引:1,自引:0,他引:1  
Rapid industrialization in such countries as Korea, Malaysia, and Taiwan suggests that the complex functional structures of cities in the periphery may appear early in development. This paper proposes a 4-stage framework for the dynamics of a system of cities in a developing country undergoing industrialization and encompassing both nonindustrial and industrial development. The synthesis is assessed with evidence from the newly industrializing Asian nations of Korea, Malaysia, and Taiwan. The 4 stages of cities' industrial change include 1) increasing primacy with industrial satellites, 2) increasing primacy with industrial satellites and nodal towns on a transport network, 3) rapidly increasing primacy with rapidly growing industrial satellites and nodal towns on the transport network, and 4) decreasing primacy with slowly growing industrial satellites and rapidly growing peripheral industrial towns. The 4-stage synthesis suggests that economic development in the periphery may occur even while the primate city maintains its hegemony over control and coordination functions. Peripheral industrial growth does not challenge this hegemony. The growth of industrial cities is, instead, part of a process of regional specialization in which the low cost labor in the periphery becomes an attraction for industry. These stages are not inevitable. Government efforts are necessary to develop rural areas in terms of social improvements (education and health), capital infrastructure (transportation and utilities), and fair payments to farmers for their outputs. These seem to be the lessons learned from the industrialization process in Korea, Malaysia, and Taiwan.  相似文献
