The role of communication in public administration has been emphasized over time in public administration theory. Nonetheless, communication—with the exception of political communication—has been neglected in scholarship. Garnett's performance predicament posits the difficulty of showing linkages between communication and performance. This paper explores the role that communication plays in achieving organizational performance through a review of research that bears on communication's direct and indirect influences on performance. The primary thrust is communication's indirect role in achieving performance by mediating or moderating the effects of organizational culture on performance, thereby adding another perspective on the culture–performance relationship. Adapting the typology of Zammuto and Krakower, two types of organizational culture—rule-oriented culture and mission-oriented culture—are examined to explore how the relationship between organizational culture and organizational performance is influenced by communication. The analysis supports the claim that communication acts as a meta-mechanism for shaping and imparting culture in mission-oriented organizational cultures, thereby influencing performance. In particular, task orientation, feedback, and upward communication have positive effects on perceived organizational performance in mission-oriented organizations but potentially negative effects on performance in rule-oriented cultures. 相似文献

We investigate the political economy of IMF forecasts with data for 157 countries (1999–2005). Generally, we find evidence of forecast bias in growth and inflation. Specifically, we find that countries voting with the United States in the UN General Assembly receive lower inflation forecasts as domestic elections approach. Countries with large loans outstanding from the IMF also receive lower inflation forecasts, suggesting that the IMF engages in “defensive forecasting.” Finally, countries with fixed exchange rate regimes receive lower inflation forecasts, suggesting the IMF desires to preserve stability as inflation can have detrimental effects under such an exchange rate regime. 相似文献

Opinion Taking within Friendship Networks 总被引:2,自引:0,他引:2

Communication within friendship networks can provide gains in efficiency that help individuals enrich their understanding of politics. Through two panel survey experiments, we demonstrate that the dissemination of an individual's opinion about the hazards posed by public policies can have both durable and significant effects on the policy judgments of friends. These effects are conditioned by both the content of the communication and the recipient's level of political awareness. Opinions emphasizing potential risks carry more weight than those that attempt to alleviate concerns about potential risks. Moreover, opinion transmission is more effective for subjects who are less politically aware when policy issues are salient; but when the political issue is more esoteric, friends who are more politically aware evidence greater opinion change. 相似文献

The consequences of administering welfare-to-work programs through county-level agencies may be the most important issue omitted from current discussions of welfare reform. An administrative geography of county welfare agencies fragments metropolitan labor markets, consigning central county residents to job-poor areas and isolating them from job-rich suburban counties. This paper illustrates this effect by mapping employment/population shifts and administrative boundaries in metropolitan Milwaukee. The paper ends with the suggestion that county agencies be allowed to play variable rather than fixed functional roles in a labor exchange process that must now accommodate a metropolitan scale. 相似文献

This essay questions the soundness of a scholarly shift awayfrom refugee studies in favour of forcedmigration studies. It contends, first, that subsumingrefugee studies into the broader framework of forced migrationstudies may result in a failure to take account of the specificityof the refugee's circumstances which are defined not just bymovement to avoid the risk of harm, but by underlying socialdisfranchisement coupled with the unqualified ability of theinternational community to respond to their needs. Second, itargues that forced migration (rather than, forexample, forced migrant) studies encourages afocus on a phenomenon rather than on the personal predicaments,needs, challenges, and rights of refugees themselves. It maythus contribute to a lack of criticality in relation to policieswhich subordinate refugee autonomy to the pursuit of more systemicconcerns. The first concern is illustrated by reference to theemergence of the internally displaced personscategory, the second by reference to the determination to findand mandate durable solutions to forced migration,including to the movement of refugees. 相似文献

Hacking trauma is prevalent in forensic cases involving genocide and dismemberment, but research into the identification of this type of trauma is lacking. The present study examines characteristics of hacking and blunt force skeletal trauma in order to determine if there is a point at which blunt force trauma becomes distinguishable from hacking trauma. Ten implements with a range of blade angles (i.e., the striking surface of the implement) were used in conjunction with a controlled-force hacking device to impact 100 limb bones of white-tailed deer (Odocoileus virginianus). Observations of the trauma included the occurrence and degree of fragmentation, the entrance widths of the impacts, and composite scores of six hacking characteristics, especially the distinctive V-shaped kerf. ANOVA tests and regression analyses were used to assess the relationships between these characteristics and the blade angles. A significant relationship (p-value = 0.011) was found between the composite hacking scores and the blade angles, indicating that blunt force and hacking trauma can be distinguished. The entrance widths of the impacts exhibited a significant relationship with the blade angles (p-value = 0.037). There was also a significant relationship between the visibility of a V-shaped kerf in the bones (p-value = 0.003), with visibility decreasing around the 60° blade angle. These data should assist in establishing guidelines to differentiate hacking and blunt force skeletal trauma in cases where the implement is on a spectrum between sharp and blunt. 相似文献
