Political parties are in a transitional phase. A declining, socially restricted membership, decreasing levels of activism and a shift towards more individualistic modes of political engagement threaten the linkage role that parties have played in modern democracy. The development of the Internet in a period of change has meant that it quickly became intertwined with debates about reviving representative political organisations. Using data from a survey of party activists in the UK (N = 4,770), this article answers questions about the perception and use of new media by party activists, the Internet's potential for members' participation and engagement and the penetration of the Internet in pre-existing political careers. In general, the article asks which role new media are playing in the transition of political parties. 相似文献

This study investigates the types of factors which can lead to government acquisition, or the “spin-in” of bio-defense technologies from small bio-technology firms. Empirical findings suggest that for small biotechnology R&D firms desiring to increase “spin-in” technology transfer, there appears to be two distinct and important influence groups—the scientific community within federal agencies, institutes, and centers, and the more managerial, policy-oriented decisions makers. We found that personal communication and networking appear to be the primary factor that leads to a successful technology transfer, however, the form and substance of personal communication and networking will differ between the two influence groups. 相似文献

We report the results of two studies designed as follow-ups to our earlier research on the comprehension of capital penalty instructions. In the first study we examine whether a California penalty instruction that was revised by the courts to improve its comprehension by jurors accomplishes this goal. In the second study we content-analyze a sample of attorney closing arguments that were given at the conclusion of actual capital penalty phases to explore whether they are likely to clarify those concepts and procedures that are so poorly comprehended in the judge's instructions. Results indicate that the revised instruction suffers from the same comprehension problems that plagued its predecessor and that attorney arguments appear unlikely to significantly reduce confusion among capital jurors. 相似文献
