Public policies to increase the efficiency of state and local governments through fostering the use of new technologies are based, implicitly at least, on theories of diffusion. Existing theories of diffusion have been found to be deficient. This paper presents an approach to the diffusion of technological innovations in state and local governments organized around the concept of diffusion milieus.A diffusion milieu contains those elements external to the organization which bring pressure to bear on the organization to alter its existing practices, which define the range of feasible alternatives to these practices, and which condition the information flow on the performance characteristics of the proposed innovation(s). These milieu components are then filtered through the internal decision-making process(es) of the organization to produce a decision to accept or reject the innovation(s). More specifically, the milieu contains (1) the specific nature of the demands upon the agency to change behavior (performance gaps), (2) the supply of alternatives to existing practices (technological change), (3) agency-executive relationships, (4) the activities of suppliers in marketing innovations, (5) the resources available to the agency to acquire new techniques, (6) the characteristics of the knowledge infrastructure which affect the search behavior and the degree of uncertainty associated with adopting new techniques, (7) the impact of intergovernmental relationships, and (8) citizen demands. The components of the diffusion milieu are then (9) related to a set of agency decision-rules concerning the adoption of new techniques.The rate of diffusion in each field will depend upon themagnitude of the components and on thelinkages between them.Functional fields differ in both respects.Research for this paper was supported by a grant from the National Science Foundation, Office of R & D Assessment. We have benefited from the helpful comments of Professor Marvin Rozen, an anonymous referee and the research assistance of Ms. Lee Ann Kozak. The views expressed in this paper are the sole responsibility of the authors. An earlier version of this paper was presented at the 1975 American Political Science Association meetings. 相似文献

Although few controversies in our political environment are as contentious as the current debate over immigration policy, the research on public opinion toward immigration is quite limited. In particular, we know relatively little about the contextual determinants of opinions on immigration issues. We address this issue by investigating the impact of migrant context on Anglo opinions toward immigration. We find that Anglo support for increased immigration is directly related to the size of the documented migrant population. Conversely, as the relative size of the undocumented migrant population increases, Anglo support for increased immigration decreases. We conclude with a discussion of the relevance of our findings for the study of immigration opinion, in particular, and the study of intergroup relations more generally. 相似文献

Interest groups seek to influence public policy. Business associations specifically seek to influence policy related to the environment in which their members operate, with the intention of making it easier for the members, and the wider private sector, to “do business.” Scholars question whether interest groups are influential and, if so, the degree to which their activity influences public policy. Even if they do influence public policy at the margins, it is questionable how effective they are in influencing legislation. As a result, there is little exploration of the factors that may determine whether business membership organizations (BMOs) are likely to be successful. This paper explores the efforts of two BMOs in Kenya to influence legislation: In one case, the BMO persuaded the government to introduce legislation to regulate an activity that had previously not been subject to legislation; in the other, a BMO sought to persuade the government to amend its own proposals to replace existing legislation with new legislation. In both cases, we find evidence that the BMO was successful, though one BMO was significantly more successful than the other. We review the factors perceived by the BMOs to have led to their success. Neither was in a position to rely on economic or other power to strong‐arm the government. Both followed a predominantly insider strategy though with occasional media back‐up. Both were successful on the more “technical” issues. Key factors include the use of a champion, engaging across government, supplying information, and providing evidence and good argumentation. 相似文献

Appraisals about the implications of stressful events that are evaluated as involving a threat to self (negative self-evaluation,
negative evaluation from others, rejection by others) have been shown to place youth at risk for the development of mental
health problems. This longitudinal study tested a protective-stabilizing interactive model, in which high maternal acceptance
was predicted to mitigate the prospective relation between threat to self appraisals and change in adolescents’ mental health
problems six months later. Participants were 89 adolescents from divorced families ages 10–12 and residential mothers. Adolescents
reported on threat to self appraisals from the most stressful event experienced in the past month. Mothers and youth reported
on maternal acceptance and mental health problems. Multiple regression analyses provided support for the protective effects
of maternal acceptance on adolescents’ mental health problems. Intervention implications are discussed.

The interaction of welfare and child support regulations has created a situation in which child support policy's incentives that discourage unwed fatherhood tend to be stronger than its incentives that encourage unwed motherhood. This suggests that more stringent child support enforcement creates incentives that reduce the likelihood of nonmarital childbearing, particularly among women with a significant chance of needing public assistance in the event of a nonmarital birth and their male partners. We investigate this hypothesis with a sample of women from the Panel Study of Income Dynamics, to which we add information on state child support enforcement. We examine childbearing behavior between the ages of 15 and 44 before marriage and during periods of non‐marriage following divorce or widowhood. The estimates indicate that women living in states with more effective child support enforcement are less likely to bear children when unmarried, especially if they are young, never‐married, or black. The findings suggest that improved child support enforcement may be a potent intervention for reducing nonmarital childbearing. © 2006 by the Association for Public Policy Analysis and Management. 相似文献
