Abstract The advent of the Internet alleviates the access bottleneck to TV distribution channels and softens licensing requirements. This lowers entry barriers to TV markets via the Internet in various forms. This paper takes the German TV sector as an example to analyse the attractiveness of TV markets for new entrants. A sequential framework for entering TV markets is introduced. The skills set of an Internet‐based TV provider for such an entry is examined. Technical feasibility, legal aspects, and potential sources of revenue are considered. Potential above average profits due to the market's oligopolistic structure, as well as an increased contestability thanks to lower market entry barriers seem to render the German TV market attractive for new entrants. In early 2002, Internet‐based TV still faced severe technical and legal constraints. The analysis suggests that once these constraints have been overcome, the Internet could be an attractive additional distribution channel for some types of television content. While existing revenue sources from the TV sector are expected to be transferable to a certain degree, the value of innovative revenue sources based on online sales cannot yet be determined. This value will depend on the future acceptance of interactivity by the viewer (e. g. Owen 1999). 相似文献

The purpose of this article is to introduce a research design, which aims to find useful pedagogical adaptations for teaching pupils with autism. Autism is a behavioural syndrome characterised by disabilities and dysfunctions in interaction and communication, which is why it is interesting to explore educational processes particularly from an interactional perspective in a class with pupils with autism. The main focus is in exploring teacher’s tacit knowledge and interactional co-regulation between the teacher and the pupils. This study is a part of a larger Finnish project, which involves the education of pupils with autism in the primary school system. In the study described, six video recordings (each about 30?min) were taken under analysis due to the uniqueness in the research context of special education: the videos are rare in that they involve only the teacher and her six pupils with autism; no helpers are present in the classroom. This study explored the phenomenon ethnomethodologically. This study indicated that it is possible to apply a general theory of interaction when exploring people with autism, although the main diagnostic criteria of autism are disabilities in social interaction and communication. It was possible to extract episodes from the behaviour of the teacher that showed her tacit knowledge becoming concrete. These results could be taken into consideration when planning and carrying out teaching in different contexts and in teacher education, too. 相似文献

The aim of this article is to gain insights into the economic impacts of the Winter Youth Olympic Games (YOG). Taking the example of Innsbruck 2012 (YOG 2012)—the first ever Winter YOG—the economic dimension of the event is comprised by calculating the primary economic impulse as well as the induced economic impulse (total economic effect). For the purpose of this study the region (Tirol) and the period of time (13th to 22th January 2012) were chosen. 相似文献

This article presents an overview of the recent literature on gendered patterns of academic choice in mathematics, science, and technology. It distinguishes in this literature micro-level, macro-level, and institutional explanations. Micro-level explanations focus primarily on psychological constructs, that is, variables at the level of the individual students. Macro-level explanations focus primarily on socioeconomic conditions and cultural understandings of gender roles. Institutional explanations focus on design characteristics of (national) education systems. After a presentation of these perspectives and of recent research progress that has been made, the authors critically discuss the lacunae that still exist in explaining cross-national variety, and provide suggestions for designing future research in this field. 相似文献

If the number of doctorates were only a function of the number of professors, Sweden should be expected to excel Norway by a factor of 1.5‐2. This figure is actually 8‐10 times as high for those faculties in which Sweden requires a Ph.D. for high‐school lecturers. Within Sweden, there is also a systematic covariation over time between the examination of doctors and the number of new positions filled as lecturers. Thus, the merit‐value of doctorates for Swedish higher education has been of great importance for the development of Swedish research in certain fields. 相似文献
