A Review of: “The U.S. Catholic Press on Central America: From Cold War Anticommunism to Social Justice,by Edward T. Brett”

In a few short years, the World Wide Web has become a standard part of candidates' campaign tool kits. Virtually all candidates have their own sites, and voters, journalists, and activists visit the sites with increasing frequency. In this article, we study what candidates do on these sites—in terms of the information they present—by exploring one of the most enduring and widely debated campaign strategies: “going negative.” Comparing data from over 700 congressional candidate Web sites, over three election cycles (2002, 2004, and 2006), with television advertising data, we show that candidates go negative with similar likelihoods across these media. We also find that while similar dynamics drive negativity on the Web and in television advertising, there are some notable differences. These differences likely stem, in part, from the truncated sample available with television data (i.e., many candidates do not produce ads). Our results have implications for understanding negative campaigning and for the ways in which scholars can study campaign dynamics.

The Influence of Perceived Confidentiality Risks and Attitude on Tanzania Government Employees’ Intention to Adopt Web 2.0 and Social Media for Work-Related Purposes

Studies show that there are many benefits of using Web 2.0 and social media in governments. However, the factors influencing government employees‘ adoption of these technologies are not well known. In this paper, the Unified Theory of Acceptance and Use of Technology (UTAUT) was integrated with two constructs, namely, perceived confidentiality risks (PCR) and attitude (AT) in order to investigate the factors influencing adoption of these technologies among government employees. The sample consisted of 600 usable responses collected from Tanzania Government Employees. To analyze the data, Structural Equation Modeling was used. Both PCR and AT were found to be influential.     

A Comparative Study of Nonprofit and For-Profit Web-Based Issue Advocacy

Abstract

Using the Web to advocate positions and actions on public issues is an emerging and potentially powerful means of shaping public opinion and action. Building on studies of Web advocacy in the political sector, this research employs content analysis to examine Web-based advocacy by U.S. for-profit and nonprofit organizations. For-profit organizations were found to engage in much more Web advocacy than nonprofit organizations. Those organizations that did engage in extensive advocacy, or were committed to multiple social values, appear to have come to adopt these postures or activities consistent with what a cost-benefit analysis of the impact on their enterprise would predict. With respect to region, the Northeast and South evidenced a higher and lower pattern of advocacy, respectively. Finally, greater financial resources predicted more extensive advocacy content generally; the particular issue areas this study examined were community focus, charitable causes, environmental issues, and diversity.     

语义Web服务发现研究及其在公安系统集成中的应用

Greek Political Marketing Online

Abstract

The new communication system of interconnected computer networks is altering the nature of political communication in many innovative and significant ways. In Greece, the development of the Internet as a mass communication medium has a history of no more than five years, and it is far from being a fully fledged medium of political communication. With the exception of relatively few cases, the use of the Internet has been shown to increase during the pre-election campaign periods. This paper presents the results of a research project, which explores the personal Web sites of the Greek parliamentarians in an off-campaign period. The research was conducted through the systematic observation, examination, and analysis of a sample of personal Web pages owned by cross-party elected members of the Greek Parliament.     

Social Media Engagement of Berlin and Prague Museums

ABSTRACT

Attracting visitors and engaging them effectively in the highly competitive and saturated environment shaped by Web 2.0 and online social networking forces museums to creatively and purposefully examine channels for extended interaction with audiences. This exploratory and comparative research aims to compare the state of social media strategies across museums of two regions and to identify the influence of applied strategies on users’ reactions. The surveyed sample considers 296 museums from two European capitals—Berlin and Prague—whose activity has been observed during a three-month period. The findings identify the differences in the approaches of museums and suggest that the frequency and characteristics of published messages correlate to the level of fan reactions, facilitating targeted relationship-building possibilities with online audiences. They further imply that the museums can influence the engagement of visitors by focusing on the particular properties of their posts, both in the sense of post structure, media application, and underlying semantic features.     

论数据库动态技术在我国电子政务建设的应用

在发展电子政务的热潮中,各种基于网络的具有互动作用的电子政务系统的建设也加紧了建设步伐,这些系统的实现有赖于基于Web的CGI、Java、ASP、动态数据库开发技术的成功应用。当前,各种数据库动态技术在实际应用中各有所长,但也不同程度地存在一些问题。我们在开发电子政务系统时应扬长避短,采用合适的开发技术,最大限度地促使电子政务建设和数据库开发技术同步发展。
