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

This article discusses historical themes that led to the civil commitment reforms of the sixties and seventies. The changes in the substantive criteria for commitment are analyzed and critiqued. The author believes that the present criteria tend to focus so specifically on various external indicia of mental illness that they render commitment difficult for many seriously ill patients. An alternative commitment scheme is discussed.  相似文献

Four unrelated hanging deaths involving young white males, all in enlisted status in the United States military, are presented. Taken in a military context, one scene served as a suicide note equivalent with the unmistakable message of extreme defiance toward military regulations. In two cases, the elaborate attire of the decedents could have lead to the misclassification of the manner of death if investigative information had not been considered. Extensive background investigation and review of medical records in the fourth case disclosed that the victim had an eight- to ten-year history of compressing his neck to cause unconsciousness. He left an extensive suicide note in which he concluded that "hanging would be good." Each case has certain unique features, as a group, the cases all demonstrate a continuum from obvious suicide to cases where the manner of death is, at first, equivocal.  相似文献

A conference was held at the State University of New York at Stony Brook in October 1984 to discuss the controversy concerning treatment of a newborn with severe congenital defects that became known as the Baby Jane Doe case. Fox provides some background information on the case to introduce a set of of six articles consisting of papers delivered at the conference. These articles deal with historical aspects of the treatment debate (Stanley J. Reiser), problems of clinical decision making (John M. Freeman), the legal issues involved (John A. Robertson), coverage of the case by the media (Stephen Klaidman and Tom L. Beauchamp), federal efforts to regulate the treatment of handicapped newborns (Lawrence D. Brown), and the alliance that arose between opponents of abortion and advocates of the rights of the handicapped (Constance Paige and Elisa B. Karnofsky).  相似文献

The future of public health law   总被引:1,自引:0,他引:1  
Developments in medicine and constitutional law dictate modification of public health legislation in the United States. Traditionally overlooked by legislators, present public health laws provide inadequate decision-making criteria and inappropriate procedures for dealing with issues. Revised legislation should provide health care officials and agencies with the tools to balance individual rights against public health necessities. This Article makes four recommendations for legislative reform: (1) remove artificial legislative distinction between venereal and other communicable diseases; (2) provide criteria defining "public health necessity" to limit discretionary exercise of police power by health officials; (3) provide strong confidentiality protections in the collection and storage of public health information; (4) empower public health officials to select from a graded series of less restrictive alternatives in dealing with public health problems.  相似文献
