Social scientists have increasingly become involved in the submission of amicus curiae or friend of the court briefs in legal cases being decided by state and federal courts. This increase has triggered considerable debate about the use of briefs to communicate relevant social science research. This article evaluates the strengths and weaknesses of various methods of summarizing social science research for the courts. It also reviews the procedures for submitting briefs developed by the American Psychology-Law Society which, in collaboration with the American Psychological Association, has submitted its first brief inMaryland v. Craig, a case recently decided by the U.S. Supreme Court.The authors wish to thank James Ogloff, Kathy Roesch, and Claudia Worrell for their comments on an earlier draft  相似文献

Technology transfer is the process by which technology originating at one institutional setting is adapted for use in another. A major impediment to the implementation of new technologies to assist with mangerial decision-making problems is a lack of communication between the technology and management communities. Development of a tool designed to bridge the technology transfer gap was the goal of this research. The result is a prototype software package which may be used on an interactive computer terminal by a manager for assistance in designing a decision support system (DSS). The four primary research tasks were:
  1. Develop a conceptual model of the DSS design process.
  2. Select and adapt, or create, appropriate software to mechanize the model.
  3. Develop a knowledge base to describe the interactiveness of various organization variables and managerial decision-making needs.
  4. Collect and analyze interview data and implement resultant production rules on the model.
Tasks 1 and 2 were accomplished first to establish the feasibility of this effort. An interview instrument was developed for Task 3. And, corporate managers from several firms were interviewed to accomplish Task 4. Using this data, a prototype production rule model (called DECAIDS for DECISION AIDS) was constructed which supports managerial decision-making from the EMYCIN production rule system used at Stanford University. The purpose of this article is to introduce the need for a Decision Support System Model. A complete copy of this research can be obtained through University Microfilms International, 300 N.

Approaches to the interagency coordination of R & D policy adopted by the governments of five West European countries and the United States are described and analyzed comparatively in terms of four variables: (1) procedures; (2) aims; (3) distribution and sources of influence among participating agencies; and (4) the frame of reference which orders governmental actions in R & D for coordination purposes. Differences stem from general features of policy formation within each system and changes over time in the conception and goals of science policy. The inherent ambiguities of the coordination concept and the difficulties in defining the perfectly coordinated system are the primary obstacles in evaluating coordination formats both within and across systems.An earlier version of this paper was presented at the annual meeting of the American Political Science Association in Washington, D.C., September 1977.  相似文献

In 2004 the Commonwealth government is undertaking a review of its drought policy. This follows expenditure in excess of $1 billion on drought relief during 2002 and 2003 and comes only a decade after similarly large expenditure on support for farmers during the drought of the 1990s. Drought support for farm businesses has been provided within the framework of the National Drought Policy (NDP) agreed by Commonwealth and state governments in 1992 and at present is in the form of interest rate subsidies. This article suggests an alternative form of drought relief for farm businesses based on the Higher Education Contribution Scheme, which is more equitable between farmers, less regressive in its impact on tax payers and less open to politicisation.  相似文献

The necessity to control environmental externalities is almost invariably given as justification for command-and-control regulation and other forms of state intervention in related markets. When even mentioned, common law remedies that protected environmental rights for centuries are quickly dismissed as either being unworkable or ineffective. A review of the common law experience indicates that the rule of law can be effective in protecting environmental rights. Indeed, it is quite possible that common law was too effective, which led to special interest demand for statute law. The rule of politics may be more attractive to rent seekers than the rule of law and markets.  相似文献
