The transparency that journalists and newsrooms can produce for their audience has long been regarded as a rather marginal criterion for journalistic quality. But new transparency models??due to the interactivity, immediacy, archiving capacity and the absent limitation of space in the internet??offer greater potentials than classical instruments in print and broadcasting. In comments, web videos, blogs, twitter feeds and social networks, journalists discuss with users and publicly account for editorial decisions. Transparency is fashionable in the digital public sphere; its evaluation, however, is not clear, but ambiguous and complex. This paper conceptualizes (self-)transparency and qualitatively classifies the available instruments in a three-dimensional matrix model. This is to facilitate the analysis of problematic areas and potential conflicts: Newsrooms demonstrating open self-reflection dismiss the ideal of ??objective journalism??. Yet, transparency is not only an ethical demand, but is also supposed to strengthen trust in journalistic products because it permits quality evaluations by the audience. An experiment shows, for the first time, that self-transparency has an effect on trust in some aspects but not as a basic principle. Analysing this interdependency, we have to distinguish between transparency of process and of product as well as between different media.  相似文献

Islamophobia is more strongly developed in East Germany compared to the western part of the country. Given the lack of personal contact with Muslims in East Germany, islamophobia is probably strongly influenced by media coverage. For this reason, the coverage of two East German regional newspapers, Nordkurier and Volksstimme, is analyzed against the theoretical background of a conjunction of the social-psychological stereotype content model with the communication-scientific concept of framing. Using content analysis and latent class analysis, two so-called stereotype frames were identified. Two thirds of all Islam-related articles use the ??cold and harm frame??. Here, Muslims are often blamed for the lethal consequences of terrorist action, their behaviour is evaluated as cold or immoral, and military interventions against them are discussed. On the other hand, one third of all Islam-related articles belongs to the ??competence and cooperation frame??. Competence is ascribed to Muslims as their success in artistic, athletic or political activities is recognized and other actors?? interest in cooperation in these areas is emphasized. Whereas the ??cold and harm frame?? probably promotes medial segregation, the ??competence and cooperation frame?? is representing an assimilative model of media integration.  相似文献

This article contributes new time series for studying the UK economy during World War I and the interwar period. The time series are per capita hours worked and average capital income, labor income, and consumption tax rates. Uninterrupted time series of these variables are provided for an annual sample that runs from 1913 to 1938. We highlight the usefulness of these time series with several empirical applications. The per capita hours worked data are used in a growth accounting exercise to measure the contributions of capital, labor, and productivity to output growth. The average tax rates are employed in a Bayesian model averaging experiment to reevaluate the Benjamin and Kochin (J Political Econ 87:441–478, 1979) regression.  相似文献

Catharsis theory is regarded as refuted. This widespread belief can be questioned for two reasons. First, most test films used in experimental studies do not meet the requirements of catharsis theory; second the social consequences of catharsis were not measured. Two films were produced for our experiment, one which meets the requirements of catharsis theory and should reduce aggressiveness and one which, according to alternative theories, should increase aggressiveness. A control group saw a neutral film. As dependent variables (a) level of general aggression, (b) aggressive inclinations in social situations, and (c) willingness to use aggressive stereotypes were measured. The film that was assumed to reduce aggressiveness increased aggressiveness even more than the film that was assumed to increase it. This surprising finding and its consequences are discussed.  相似文献

This article explores the change in the level of competition in rural banking markets after the deregulation that occurred following passage of the Riegle‐Neal Act of 1994. Using an empirical model that utilizes both the number of banks and the value of deposits in a cross‐section of 278 rural markets, we decompose the impact of the entry of new banks into resulting changes in per capita demand and the costs/profits of local banks in 1994 and 2004. The results support the view that local banking markets have become more competitive since the mid‐1990s.  相似文献
