Although medical research involving the use of persons with mental illness is critically important, in order for the research to be ethical and legal there are certain considerations and restrictions which should be immediately readdressed in order to insure that the welfare of these vulnerable research subjects is protected, and their best interests are assured. A brief historical examination of medical research codes, guidelines, recommendations and Federal Regulations reveals the various considerations and restrictions on informed consent and accountability applicable to the use of persons with mental illness in medical research. Several concerns are raised about how these considerations and restrictions have been interpreted, and specific recommendations are offered to improve them immediately by means of representation from consumers and/or their families, and organizations, e.g., NAMI members.  相似文献

Abstract

In this essay, I examine the contextual and historical relationship between the national and regional associations in American sociology. Four findings emerge from the analysis of this relationship. First, the regional associations underutilize the populations they represent. Second, the constituencies of the national and regional associations are diverging. Third, the regional associations appear no longer to serve as a viable pathway for involvement in the leadership of the national association. Fourth, the disciplinary visibility of the regional associations journals has declined, on average, since 1990. These four outcomes reflect a disciplinary drift toward internal differentiation, which can only be understood as a manifestation of the culture of American sociology. Specifically, the discipline is becoming increasingly incoherent as a result of the inaccurate perception it holds of itself as a science. This misperception, historically embedded within the disciplinary culture of American sociology, appears to guide the discipline toward an overemphasis on the production of research and the establishment of a governance structure that draws heavily on faculty from doctoral-granting departments. Accordingly, following from my analysis of the discipline's culture. I concude that sociology is better positioned as a profession than a science.  相似文献

While union density in the public sector has increased in recent decades, private sector union density in the U.S. has declined steadily since the mid-1950s. Scholars have evoked a variety of explanations to account for the decline in union membership, but substantially less attention has been devoted to understanding the contribution of the union organizing process as governed by the National Labor Relations Board (NLRB). In this paper, we focus on two aspects of this process: union organizing effort (the effort to establish union representation elections to organize non-unionized workers) and union organizing success (success in winning union representation elections). Using annual time series data for the U.S. from 1948 to 2004, we show that there has been a long-term decline in both union organizing effort and union organizing success, which likely contributes to declining union density. We focus on three explanations for these changes: the political–legal environment for unions, deindustrialization and globalization, and employer opposition to unionization efforts. We find that each of these factors contributes to organizing effort and success and conclude with a discussion of the implications of this research for future mobilization efforts.  相似文献
