Kulturradio in Deutschland 2010: Versuch einer Bestandsaufnahme

Cultural radio in Germany has undergone a radical change since the turn of the millennium. The public debate on cultural radio programmes is characterized by the voices of different agents and stakeholders. In this essay I try to reconstruct and connect the different perspectives and levels of change. The inspection focuses firstly on the public service cultural radio’s dilemma of legitimation between audience rating and educational mandate. Secondly the paper describes the symbolic fight for the power of definition of legitimate culture between the economy and cultural authorities. The analysis also addresses radio’s position in the contemporary media repertoire, cultural radio programmes in Germany in general, and the differentiation between public services and private cultural radio programmes. Finally the following factors of change will be identified: (a) the change of radio’s social function in the media repertoire, (b) the media system as general framework, (c) the power of legitimation, (d) the understanding of culture, (e) technological progress, and at last (f) the cultural radio programmes themselves.     

Arbeitsbezogene Erwartungen und Commitment von IT-Freelancern

Seit einigen Jahren besteht eine Tendenz zur Flexibilisierung von Besch?ftigungsverh?ltnissen. Dennoch hat sich die Forschung bislang nur wenig damit befasst, welche Konsequenzen diese für die Loyalit?t und das Commitment von freiberuflich t?tigen Mitarbeitern aufweist. Daher beantwortet der Aufsatz auf Grundlage einer empirischen Studie unter IT-Freelancern die Frage, unter welchen Bedingungen Freelancer Commitment zu einem Unternehmen empfinden. Au?erdem wird analysiert, welche (unterschiedlichen) Erwartungen Freelancer an ihre Arbeit richten. Insgesamt zeigt sich, dass die Befragten durchaus Commitment gegenüber ihrem Arbeitgeber empfinden. Insbeondere eine affektive Bindung ist zu beobachten.     

Randomized response: Estimating mean square errors of linear estimators and finding optimal unbiased strategies

Summary General procedures are described to generate quantitative randomized response (RR) required to estimate the finite population total of a sensitive variable. Permitting sample selection with arbitrary probabilities a formula for the mean square error (MSE) of a linear estimator of total based on RR is noted indicating the simple modification over one that might be based on direct response (DR) if the latter were available. A general formula for an unbiased estimator of the MSE is presented. A simple approximation is proposed in case the RR ratio estimator is employed based on a simple random sample (SRS) taken without replacement (WOR). Among sampling strategies employing unbiased but not necessarily linear estimators based on RR, certain optimal ones are identified under two alternative models analogously to well-known counterparts based on DR, if available. Unlike Warner’s (1965) treatment of categorical RR we consider quantitative RR here.     

Unterschichtfernsehen? Integration und Differenzierung von bildungsspezifischen Teilpublika

Analyses of the development of the dual broadcasting system are dominated by communicator-centred approaches, which test the hypothesis of convergence by means of content analysis and generate contradictory results. As of today, the recipient-orientated perspective has gained only little attention. This paper concentrates on media use in the period from 1988 and 2004, after the dual broadcasting system was established in Germany. Using longitudinal data, we examine whether the use of the most important television channels depends on education. The main question is whether the introduction of the dual broadcasting system in Germany has differentiated the composition of the television audience or whether broadcasting still has an integrating effect. The results contradict the differentiation hypothesis.
