This paper examines research on the diffusion of innovation, the final stage in the process of technological change. The focus rests primarily on two traditions in diffusion research: that of economists and that of sociologists. Diffusion researchers in these and related disciplines have made significant contributions to the understanding of the dynamics of processes of change; yet the state of the art in diffusion research is not equal to the sum of its parts. This is due in large measure to disciplinary parochialism: scholars have concentrated on those innovations, diffusion environments, explanatory variables, and analytical methodologies which are most compatible with their particular disciplines, despite the fact that diffusion is not a discipline-specific phenomenon. Deficiencies in current understanding of diffusion are examined in the context of this and other significant problems. The paper concludes by considering the policy relevance of diffusion research and suggesting issues with which future research might productively be concerned.The following individuals have been most helpful in stimulating and directing my interest in this subject and in criticizing this paper: Richard R.

This multisite assessment of five, court-affiliated parent education programs incorporates information from 3,000 exit surveys by attendees, 602 telephone interviews with willing parents six months later, comparisons with 145 divorcing parents who did not attend a program, and reviews of court activity. Parents report high levels of satisfaction with the programs and credit them with helping to sensitize them to their children's needs and making visitation more successful and enjoyable. Although attendees report better compliance with divorce decrees, comparable proportions of parents in treatment and comparison groups report conflict over child custody and access, and a review of court files shows identical litigation patterns for both groups over a four-year period of time . 相似文献
Behavior in social-dilemma (mixed-motive) situations has been of great interest to economists, psychologists, and negotiation scholars. In this study, we used a threshold social-dilemma game to examine factors that have not yet been investigated and that may have an impact on behavior in these settings: gender and group identity. We found that, for women, interacting with members of a naturally occurring group increased coordination and efficiency, while for men, interacting with members of a naturally occurring group decreased coordination and efficiency. Psychological literature on gender differences and group interdependence explains these differences. We conclude by discussing the implications of these results for gender differences in negotiation behavior. 相似文献

This study examined organizational factors influencing the availability and accessibility of IPV services for refugee and other vulnerable immigrant women in the U.S. from the perspectives of social service providers. This qualitative study used a purposive sampling approach to recruit 57 social service providers. Researchers analyzed data generated from individual interviews and focus group discussions using a thematic approach. The analysis generated four themes reflective of structural and systemic factors shaping the availability and accessibility of IPV services for immigrant and refugee women in the U.S.: (1) We weren’t ready, (2) No place to go, (3) Time is not on our side, and (4) Can’t do it alone. The analysis illuminated the extent to which service demands outweighed organizational capacities and the rigidity of service timelines that failed to meet needs. A pervasive thread of ethical dilemmas emerged, affecting the availability and accessibility of services. Overall, the findings form a compelling argument for structural shifts in policy and funding, and for fostering strong inter-sectoral coordination to combat barriers to services. The study reiterates the importance of addressing inter-agency collaboration in IPV research, policy, and practice.
This article outlines recent debates over nuclear energy and wind farms in an age of growing concern about climate change. Proponents of these technologies have used “trade‐off” frames to promote these technologies in the face of current and potential opposition to them. This article examines the nature and limits of the trade‐off frames being used and their probability of success. We argue that using the language of trade‐offs is generally a suboptimal framing strategy: trade‐off frames remind the public of the costs associated with particular policies, and therefore play into the hands of policy opponents. However, policy advocates may turn to them when the costs of a technology are well known and are perceived as high. In such cases, trade‐off frames may help to justify controversial policy solutions. Like any frames, the trade‐off frames used in the debate over climate change solutions both illuminate and obscure the deeper issues involved in energy policy reform. 相似文献
