This article introduces to policy studies the concept of valence, which we define as the emotional quality of an idea that makes it more or less attractive. We argue that valence explains why some ideas are more successful than others, sometimes gaining paradigmatic status. A policy idea is attractive when its valence matches the mood of a target population. Skilled policy entrepreneurs use ideas with high valence to frame policy issues and generate support for their policy proposals. The usefulness of the concept of valence is illustrated with the case of sustainability, an idea that has expanded from the realm of environmental policy to dominate discussions in such diverse policy areas as pension reform, public finance, labor markets, and energy security. As the valence of sustainability has increased, policy entrepreneurs have used the idea to reframe problems in these various policy areas and promote reforms.  相似文献

This paper investigates persuasion as a means of influence for the Federal Reserve Chairman in meetings of the Federal Open Market Committee (FOMC). Using textual records of FOMC meetings, federal funds rate targets have been recorded for Committee members who served in the Arthur Burns era (1970–1978). Results show that Burns-member differences in stated funds rate targets were lower when Burns made recommendations early in the meeting, consistent with the hypothesis that the Chairman is persuasive. Additional results show that members’ tendencies to respond to Burns's recommendations were related to their personal and political loyalties.  相似文献

This article builds on the recent exchange between Jim Buller and Stephen George on the subject of British 'awkwardness' in relation to the European Union. While it engages with both authors, the article also seeks to bring the state back into the analysis. It makes a connection between the structure and organisation of the state and the behaviour of domestic political actors.  相似文献

Super-optimum solutions to public policy problems are ones that enable conservatives, liberals, and other major viewpoints all to come out ahead of their best initial expectations simultaneously. Thinking in terms of multiple goals and alternatives facilitates the development of mutually beneficial packages, possibly with the aid of spreadsheet-based software that enables one to better deal with the multiplicity of goals and alternatives. This article describes how super-optimum solutions might be applied to abortion policy and deals with auxiliary policies concerning birth control and adoptions. It also addresses related policies that focus on the Chinese population problem. Chinese abortion policy involves a battle between women who do want to stay pregnant and a society that would like to facilitate pregnancy termination. American abortion policy involves a battle between women who do not want to stay pregnant and a society that is reluctant to facilitate abortions.  相似文献

This study examined the influence of pubertal timing upon family interactions in normal and psychiatric adolescent samples. An important feature of our approach is its emphasis upon micro-analysis of family behaviors (individual speeches) and family processes (theoretically specified speech pairings). Rather than assume that global family patterns (e.g., power) shift in response to pubertal changes, we follow how types of speeches and speech sequences are associated with different pubertal timing. Using the previously constructed family coding system, the Constrainig and Enabling Coding System, we found that on-time adolescents and their parents differed from both off-time groups (early or late). These results are discussed in terms of current implications and suggestions for future research.An earlier version of this paper was presented at the SRCD Study Group on Timing of Maturation, October, 1983, at the Education Testing Service, Princeton, NJ.

Since 1958 NASA has invested approximately $3.7 billion in life sciences R&D in the support of the successful human space flight program. There are numerous studies documenting the spin-off technologies that can be traced to NASA research and development activities. Most of these studies describe the technologies and their uses; however only a few measure the economic impact of the spin-offs and most of these are benefit/cost studies that tend to overstate benefits or underestimate costs. This study takes a different approach, measuring only economic impacts to the companies that developed successful spin-off products from NASA life sciences investments. A personal interview was conducted with each company and the benefits are conservatively estimated as the value-added by the NASA technology to the company's output and the amount of additional private R&D stimulated by the NASA R&D.This pilot study of fifteen companies, using a very conservative measurement technique, found a large return to companies that have successfully commercialized NASA life sciences spin-off products. Value-added benefits totaled over $3.7 billion in life sciences R&D in the support of the successful human space flight program.
