This article explores factors which influence volume and structure of science programming by German TV broadcasters, focusing on influences of the national channel pattern. Based on a comparison of the German market with ten others, it identifies three factors as relevant especially for the large volume of science programming in Germany:
- The comparably large segmentation of the public TV market.
- The comparably high number of mid-sized commercial channels with market shares between 5 and 10 %.
- The comparably low dependency of public service channels on advertising income.

The scientific landscape is subject to constant change but the recruitment problem within the field of communication science and media studies in the German-speaking countries persists. To explore this problem the present study investigates the working conditions of the non-permanent faculty (PhD students and postdocs). A special focus is set on job satisfaction because it presumably increases the likelihood for continuance in academia. An online survey among 504 PhD students and postdocs shows that they are, overall, satisfied with their jobs. However, occupational uncertainty is perceived as a major problem. OLS regressions reveal that the strongest predictors of job satisfaction are mentoring satisfaction and terms of contract. The relation between job satisfaction and publication output proves to be more complex than anticipated. Based on the results a set of recommendations is put forward. 相似文献

An increase of broadband demand is forecasted by transitional methods that consider the effect of this increase through many
factors, such as customer requirement diversification, and new service introduction and deployment under competition. Broadband
demand forecasting has become important for closing the digital divide, promoting regional developments, and constructing
networks economically; therefore, a demand forecast model that considers the mechanisms of market structure is necessary.
In this paper, a demand analysis method for broadband access combining macro- and micro-data mining is proposed, and the service
choice behaviour of customers is introduced as a customer model not only to express the macro trend of market structure, but
also to consider area marketing. The proposed method can estimate the potential demand, determine the point at which broadband
demand growth peaks in a specified area, and support a decision for ultra high-speed broadband access facility installation. 相似文献

Escapism is one of the oldest concepts for the explanation of media use but is still lacking theoretical differentiation. The dimensions reason, means and duration of escape are used to differentiate three modes of escapism: modification, postponement and repression. Repression should be of special interest for communication science because media use on the one hand and long phases of escapism on the other hand are of higher probability in this mode than in the others. Hypotheses are formulated and empirically tested for the existential issues of death and the meaning of life. Results show that television is the preferred mean of escaping from displeasing thoughts. On the other hand we do not find a connection between the amount of television use and thinking about existential issues. The hypothesis of a narcotic dysfunction is not confirmed. For the matter of existential issues television seems to offer escape and stimulation at the same time. 相似文献

A true democracy is based on political competition. Political parties set up programmes and suggest solutions which the electorate is then asked to choose between. Competition for tomorrow??s leadership positions can only be fair if today there are equal opportunities for all parties. The German legislative body passed several laws which are meant to guarantee equal opportunities in this contest. In times of an ever increasing importance of the mass media for political communication, this paper is meant to answer the question of whether??besides equal political opportunities??there is something like equal media opportunities, and if so, which indicators can be used to measure them. After a broad theoretical examination, an empirical analysis of the media coverage prior to the general elections in 1998, 2002 and 2009 follows. It reveals that??from a quantitative point of view??there certainly are equal media opportunities for the political parties sitting in the German Bundestag. The chances for media coverage are, especially for smaller parties, better than the gradation of equal chances by formal regulations. 相似文献

This paper analyses both quarterly data from the Confederation of British Industry (CBI) Survey on respondents’ expectations
of recent and forthcoming manufacturing output and monthly Office of National Statistics (ONS) figures on actual manufacturing
output within the UK. Quarterly output expectations of the CBI manufacturers are explained from the monthly ONS observations
using a bounded rationality approach. The logistic formulation models the diffusion process across respondents. There is a
backward-looking CBI Survey perspective, explained by past ONS observations, and a forward-looking perspective, explained
from future ONS statistics. Also, the forecasting of monthly manufacturing output from earlier values, along with the quarterly
CBI Survey information, is examined and tested against the alternative Pesaran/Thomas method. The study provides econometric
evidence for the validity of the logistic model and shows that bounded rationality can explain the formation of predictions
among business managers in the UK manufacturing sector. The emerging consensus from the literature, supported by this paper,
is that the logistic format is a superior approximation to the true data generating process compared with the earlier standard
Anderson/Pesaran/Thomas approach. An adjustment to the Survey is used, which achieves perfect symmetry with up and down versions
of the data. The benefits of this adjustment are tested in the forecasting section.
