Stale economic news,media and the stock market

I employ a classification of headlines from newspapers and wire services to examine whether stale macroeconomic news affects stock prices. Unlike with individual stocks, the cost of obtaining information about major economic releases is relatively low. Thus, stock prices should adjust to economic news announcements prior to their coverage in newspapers. I find statistically and economically significant relationship between stale news stories on unemployment and next week’s S&P 500 returns. This effect is then completely reversed during the following week. These findings show that investors are affected by salient information and support the hypothesis that investors overreact to stale macroeconomic news reported in newspapers.     

THE FUTURE OF PUBLIC MEDIA CULTURES

This paper seeks to tie in the arguments that can be connected to the development of a global media culture and concerns around cosmopolitan forms of democracy. This is done by considering arguments for: (i) a global human right initiative in respect of global media conglomerates; (ii) technological change in respect of digital cultures; and (iii) the arrival of what Castells'shas described as the culture of 'real virtuality'. These views and perspectives are assessed in terms of the contributions they are likely to make towards what I call a 'cautious cosmopolitanism'. Finally I seek to make some definite policy recommendations that might help foster conditions in which cosmopolitan democracy could flourish.     

A theoretical perspective on “fear” as an organizational motivator for initiating public relations activities

This exploratory study identifies the correlation between perceived fear and the public relations activities of an organization. A survey of forty public relations professionals in Florida confirms that fear is a critical causal factor that motivates an organization to initiate or undertake public relations activities. The effect of fear on the public relations activities of an organization differed by public relations area. In addition, there was a gap between perception and actual public relations activities. Crisis and issues management were the areas most affected by perception, but in application media relations was the most practiced.

FROM THE CRADLE TO THE GRAVE: AUSTRO-MARXISM AND CULTURAL STUDIES

The political theory and practice of Austro-Marxism provided an understanding of culture as an area of political conflict and as a class-based way of life. As a cultural and educational movement, Austro-Marxism defined the framework for transdisciplinary extramural cultural studies. An Austro-Marxist cluster defined by a number of scholars associated by political orientation and an alternative form of academic institutionalization emerged in interwar Vienna. This cluster disagreed with the paternalistic claim of leading representatives of the SDAP. Nevertheless, the SDAP defined the pluralistic framework for the formation of Austrian cultural studies. Socialist-oriented scholars such as Otto Neurath, Edgar Zilsel, Paul Lazarsfeld and Marie Jahoda developed a materialistic idea of culture focused on the social conditions of cultural practices. Furthermore, they provided a profound understanding of mass culture and popular culture.     

TRANSFORMING DISCOURSE INTO PRACTICE: COMPUTERHYSTORIES AND DIGITAL CULTURES AROUND 1984

This paper discusses some theoretical approaches to the question of how culture, technologies and the social interact. These considerations result from the author' research in the genesis of digital cultures in the 1980s. The paper begins by outlining the author' research project, and then continues with a discussion of some of the most influential approaches in the cultural studies of technology.This article then presents a small sample of the author' analysis, which combines narratological and discourse analytical methods with practice-oriented cultural theories, such as those of Pierre Bourdieu, Régis Debray and Bruno Latour.     

The impact of newsroom changes and the rise of social media on the practice of media relations

Recent changes in American media have resulted in direct impacts on the work of PR professionals, from newsroom reductions in traditional media outlets to the rise of social media. This study examines changes in the media relations dynamic with qualitative, in-depth interviews from 12 PR professionals in a medium, eastern U.S. city. Findings include PR professionals doing less traditional media relations, mostly attributable to downsized newsrooms, and frustration with the resulting dearth of institutional knowledge, influx of young, inexperienced reporters, and shallow stories. While participants see opportunities to inject unfiltered messages in media, overall they value reporter relationships and using social media in communication with them and in their job. Although new media are seen as one more task on an already very full PR plate, participants acknowledge their importance and growing relevance. Overall, PR professionals see their and the industry's future including both traditional and new media.

Media manipulation in the Sanlu milk contamination crisis

This study analyzes crisis communication strategies in a transitioning media environment, specifically, Sanlu Group's crisis communication strategies during a quality control crisis in China. Analysis reveals Sanlu manipulated its relationships with local Chinese government and media to reduce media coverage and online searches regarding the contamination of infant milk formula. The case provides evidence that media can be pressured into manipulating information flow through both traditional and online media and suggests a need for additional research on crisis communication in transitioning media environments.
