This article examines one issue in how public relations students are socialized in their understanding of the value and power of social media in the practice of public relations. The public relations academic research about social media is explored, as well as the professional claims about the value of social media as a public relations tactic. The researchers conducted a content analysis of 1 year of Public Relations Tactics issues. The data are viewed through the theoretical frame of the socialization literature ( Jablin, 1987). The results suggest that claims of social media power far outweigh evidence of social media effectiveness as a communication tool. A disconnect exists between what authors of Public Relations Tactics pieces view as the potential for social media and the research findings about the effectiveness of social media. The final section of the article discusses the implications for public relations educators, professional associations, and practitioners as they consider social media tactics in public relations strategy.  相似文献

Abstract

Severe Acute Respiratory Syndrome (SARS) is the first major international epidemic of the twenty-first century. In a few short months it spread to every continent, infected 8,096 people, and claimed the lives of 774. It hit older persons particularly hard; it killed 50 percent of the infected of that age category.

The rate of plague's spread from one country to another has greatly increased as the globalization of the world's economy has produced rapid daily transportation of people, products, plants, animals, and, of course, microbes. Each day cities are at risk for the invasion of deadly infectious diseases. While international expert agencies such as the World Health Organization stand by to help fight outbreaks, ultimately, plagues are fought in the local community.

I discuss two theses: (1) To successfully contain and fight a major epidemic the capacity of the community's health care system must be enhanced by its functional linkages to external expert and bridging organizations and systems of organizations; and (2) that the extent to which a community's health care system can draw on external expert and bridging organizations and systems is a function of the degree to which the political state in which the community is embedded facilitates for fails to facilitate) those linkages.

My focus is on Hong Kong and the cities of the People's Republic of China; they were at the epicenter of the SARS outbreak, and it was from them that the contagion spread to other countries. Findings show that plagues are not only matters of biology and health, but also matters of politics, power, and international relations.  相似文献

The EM algorithm is a popular method for maximizing a likelihood in the presence of incomplete data. When the likelihood has multiple local maxima, the parameter space can be partitioned into domains of convergence, one for each local maximum. In this paper we investigate these domains for the location family generated by the t-distribution. We show that, perhaps somewhat surprisingly, these domains need not be connected sets. As an extreme case we give an example of a domain which consists of an infinite union of disjoint open intervals. Thus the convergence behaviour of the EM algorithm can be quite sensitive to the starting point.  相似文献

Issues management developed as a long-term process interested in the continued health and success of organizations. This essay presents a contemporary issues management case that uses inoculation and a priori solutions as issues management tactics. The case study involving Johnson & Johnson’s responsible dosing campaign demonstrates that organizations perceived to have a high standard of corporate social responsibility are not above using deceptive tactics to protect their brand.  相似文献

Change and Stability in Presidential Popularity at the Individual Level   总被引:1,自引:0,他引:1  
This article employs a three-wave panel to examine change andstability in the popularity of the president. By survey standards,the item is found to be quite reliable, approaching the reliabilityof party identification. Change in the item can be predictedusing measures of political interest and sophistication, partisanship,and strength of presidential approval or disapproval.  相似文献

This paper examines various conceptual approaches to the etiology of child abuse and reports the results of an original study. Data on 99 families with children who were court adjudicated as having suffered non-accidental trauma were analyzed by means of a cluster analysis (hierarchical nearest-neighbor clustering). Four empirically-derived clusters of family/case attributes are described and then discussed as representing separate etiologies of child abuse. The implications of this typology are also discussed as they relate to clinical practice and social policy.  相似文献

Abstract The persistence of ethnic settlement in rural regions of the United States is well documented. Yet, there has been little discussion of techniques which allow the identification of the geographic extent and concentration of distinctive ethnic populations. Amish-Mennonite settlement constitutes a unique component of the rural landscape. A wide range of visual clues alert the observer to their presence, but without painstaking field surveys it is difficult to establish their geographic extent. This paper examines four approaches to the identification of Amish-Mennonite settlement. These are county-based population data on religious affiliation, the location of Amish church districts and Mennonite churches, topographic maps, and surnames and cadastral maps. Topographic maps proved unsuitable, but each of the other approaches produced reasonable approximations of the areal extent of Amish-Mennonite settlement. Surnames and cadastral maps present good possibilities for the identification of other ethnic populations in rural regions.  相似文献

Ostensibly, the approval of legalized casino type gambling in the Netherlands was intended to combat illegal and uncontrolled gambling. Very early on, however, the plan conceived and implemented by the Netherlands Parliament demonstrated serious mismarketing strategies and tactics. The new legal casinos were appealing to people other than those engaged in illegal gambling, in particular foreign tourists and local high rollers. This paper attempts to analyze the ultimate process of goal displacement, as the state casino industry allowed economic objectives to supplant desires to utilize legal casinos primarily as controls over illegal gambling.  相似文献
