A Study of Reputational Community Leaders Using The Concepts of Exchange and Coordinative Positions*
The general purposes of this study were to investigate the group and organizational affiliates of reputed community leaders in a rural community. The specific hypotheses were that the higher one is ranked as a reputational leader, (1) the more exchange influence he will likely have accumulated through occupying economic, kinship, occupational, ownership, and political-governmental positions which are reputedly influential in the community, (2) the more likely he is to be an active participant in formal and/or informal coordinative interstitial groups in the community, and (3) the more likely he is to be an active participant in those formal coordinative groups which are reputed to be influential over community affairs. The hypotheses were tested by comparing the sets of rankings of twenty-eight reputational leaders with (1) their rankings in terms of exchange positions scores, (2) their rankings in terms of social participation scores, and (3) their rankings in terms of weighted social participation scores. The results of the study tended to support the hypotheses, as stated, for the community involved. 相似文献

At present, the ‘freedom of information’ concept has particular appeal to various democracies seeking to realize or refine a popular right to government information. The American experience with this construct provides both a significant theoretical model and a legislative realization of this idea. However, drafting imperfections and political tampering with the policy purpose of the Freedom of Information Act are apparent in the legislative history of the Federal statute and, hopefully, can be avoided by other nations pursuing this type of law. In addition, the United States has developed privacy of information and has sought to reconcile it and official secrecy with the ‘freedom of information’ concept. While the former is regarded as a valuable symbiont the latter appears to be a dangerous competitor to the effective realization of ‘the people's right to know’. 相似文献

Little research exists on effective strategies to prevent methamphetamine production, distribution, sales, use, and harm. As a result, prevention practitioners (especially at the local level) have little guidance in selecting potentially effective strategies. This article presents a general causal model of methamphetamine use and harms that reflects the available findings from either research specific to methamphetamine or from alcohol and other illegal drugs, and suggests prevention approaches and strategies that communities might use based upon research evidence and experience. Community methamphetamine prevention can use the public health and safety perspective applied to other substance abuse prevention. Analyses of the complex system of intermediate variables that interact to affect methamphetamine use and harms suggest that multiple reinforcing prevention interventions may have the greatest potential effectiveness. 相似文献

What is the role of a country's financial system in determining technology adoption? To examine this, a dynamic contract model is embedded into a general equilibrium setting with competitive intermediation. The terms of finance are dictated by an intermediary's ability to monitor and control a firm's cash flow, in conjunction with the structure of the technology that the firm adopts. It is not always profitable to finance promising technologies. A quantitative illustration is presented where financial frictions induce entrepreneurs in India and Mexico to adopt less‐promising ventures than in the United States, despite lower input prices. 相似文献
