The nature of the Internet--the ease of access, the chaotic structure, the anonymity, and the international character--all furnish terrorist organizations with an easy and effective arena for action. The present research focuses on the use of the Internet by modern terrorist organizations and attempts to describe the uses terrorist organizations make of this new communication technology. Is the use of the Internet by terrorists different from that of other, "conventional" means of communication? How can governments respond to this new challenge? The population examined in this study is defined as the Internet sites of terrorist movements as found by a systematic search of the Internet, using various search engines. The sites were subjected to a qualitative content analysis, focusing on their rhetorical structures, symbols, persuasive appeals, and communication tactics. The study reveals differences and similarities between terrorist rhetoric online and in the conventional media.  相似文献

The growing presence of modern terrorism on the Internet is at the nexus of two key trends: the democratization of communications driven by user-generated content on the Internet; and the growing awareness of modern terrorists of the potential of the Internet for their purposes. How best can the terrorists’ use and abuse of the Internet be countered? As this article argues, the answer to violent radicalization on the Internet lies not in censorship of the Internet, but in a more sophisticated and complicated strategy, relying on the theoretical notion of “noise” in communication process theory.  相似文献

Abstract

In summer 1985, a TWA plane was hijacked by Shiite terrorists to Beirut creating what turned to be one of the most impressive spectacles of the mass‐mediated “theater of terror.” After the event the American media were blamed for fanning the crisis atmosphere, giving the terrorists the publicity they craved, abetting the terrorists by reporting U.S. military movements, holding a brutal competition among themselves to get exclusive footage or interviews, harassing the hostages’ families, negotiating directly with the terrorists, milking the hostages still held by the terrorists for political and ideological declarations, and propagandizing the terrorists’ anti‐U.S. and anti‐Israel messages. The resulting debate that followed these accusations, illustrates the lingering argument regarding media and terrorism. While some claim that “the media are the terrorists’ best friends. The terrorist act by itself is nothing. Publicity is all”,1 others argue that the media are avoiding the “real terror” for ideological reasons, averting Western public opinion from U.S. terrorism by underreporting its share in Third World Terrorism.2 The ideological loadings of definitions and arguments are combined with confused interpretations of media effects and public opinion to yield an endless, futile debate. The purpose of the paper is to conceptualize basic effects of mass‐mediated terrorism by relating media effects studies to the case of terrorism and public opinion.  相似文献

Using firm-level data from Mexico, this paper investigates the firm characteristics associated with participation in credit markets, access to training, tax payments and membership in business associations. We find that firms which participate in these institutions exhibit significantly higher profits. Moreover, firms that borrow from formal or informal sources and those that pay taxes are significantly more likely to stay in business but firms that received credit exhibit lower rates of income growth. These results persist when firm characteristics that are arguably correlated with unobserved entrepreneurial ability are controlled for. Our findings suggest that the significant within-country differences in firm productivity observed in developing economies are due in part to market and government failures that limit the ability of micro-firms to reach their optimal sizes.  相似文献

The academic field of communications continues to face several challenges related to its disciplinary development. From an epistemological perspective, the definition of its object of study presents a still unfinished conceptual elaboration which would have made possible a more solid reflection vis-á-vis the new technologies that enable communicative acts in the framework of the media. This article seeks to provide elements that may strengthen this category in view of the Internet as an innovation that offers unprecedented possibilities for interactive communication not only due to the space-time compression it entails, but also to the rhizome structures through which information flows. It argues that the Internet is a communications media with unknown possibilities for expression and dissemination, based mainly on the social uses of hypertextual foundation which facilitates the operation of one of the most frequently used communication environments: the World Wide Web.  相似文献

This article seeks to interrogate the idea of “race,” nation, and multiculturalism in Malaysia from the perspective of cultural studies, in particular that of cultural translation and postcolonial theory. It employs the concept of cultural translation to examine the processes of cultural change and transfer both from the perspective of state policies and nationalistic discourses as well as the discourses and practices of the people. The central idea is to argue for a more flexible understanding of race identities in the move toward a conceptualizing of Malaysian-ness as a national and cultural identity that takes into account the social practices and experiences, imaginings, and expressions of the people. A reading of Yasmin Ahmad's film Sepet lends credence to the article's assertions about the emergence of trans-racial identities on the ground that contest the pedagogic stability of state-defined race identities. The article enters debates on the politics of race and identity in Malaysia through the controversial state-initiated concept of Bangsa Malaysia, which it here advances as an alternative model of multiculturalism and national belonging that effectively displaces the National Culture Policy as well as other hegemonic cultural formulations and political constructions.  相似文献

ABSTRACT

Millions of individuals and families in the United States do not have access to stable housing. Recent policies in the United States and the rest of the developed world emphasize programs intended to prevent homelessness through temporary financial assistance. This article explores the impact of the largest homelessness prevention program in U.S. history, the Homelessness Prevention and Rapid Re-housing Program (HPRP), on residential instability, using a national sample of families with children enrolled in school. The identification strategy exploits variations on the location of HPRP providers. Using data on the ratio of K–12 students experiencing homelessness in school districts, we find that HPRP is associated with reductions in the percentage of homeless students for districts closer to an HPRP provider. However, the impacts of HPRP fade out when program benefits end, bringing into question whether homeless prevention can help families achieve self-sufficiency in the long run.  相似文献

The authors documented and evaluated experimental gunshots to a skull-brain model with high-speed photography and subsequent radiographic examination for comparison of the morphologic findings in the model. The artificial skull was a polyurethane ball constructed in layers, with a porous diploe sandwiched between a tabula externa and a tabula interna. The brain itself was simulated with gelatin 10% at 4 degrees C, a material well known in wound ballistics. Gunshots were fired at the model from a distance of 10 m and documented with high-speed photography (up to 50 million frames/sec). Subsequently, a complete examination of the artificial skull was performed, including spiral computed tomography (with two-dimensional and three-dimensional reconstructions) and classic skull autopsy. The high-speed photographs clearly showed the dynamic development of the skull fracture system from an external perspective. The subsequent radiographic examination of the entire head volume created two-dimensional reformations in any plane and three-dimensional reconstructions of the gunshot injury of the polyurethane skull-brain model, especially the wound channel and the fracture system. Thanks to the model and high-speed photographs, the dynamic development of the morphology of a gunshot wound could be documented and studied. The data from computed tomography, using two-dimensional and three-dimensional postprocessing with a perspective view, were very similar to those from classic head autopsy, but derived in a hands-off and nondestructive manner. This examination method leads the way to radiographic digital autopsy or virtual autopsy.  相似文献
