Abstract

This multiple-case study explored television programming products offered by U.S.-originated cable networks—namely, Music Television, Cartoon Network, Entertainment and Sports Programming Network, and Discovery Channel—in such Asian markets as Japan, Singapore, and Taiwan and attempted to identify factors that shape their programming strategies. On the basis of theoretical foundations concerning product standardization and adaptation in international marketing research, this study found that various external and intrafirm factors, ranging from host country's cultural and environmental characteristics to network's business orientation, are relevant to the decision on programming products by global television networks.  相似文献

This article investigates the issue of the relation between market competition and programming diversity in Taiwan's TV market. For more than 20 years, Taiwan's TV market had an oligopolistic structure with 3 networks dominating the market. With the popularity of satellite TV during the 1990s, the oligopoly rapidly ended. This study examines how programming diversity was affected by the changing TV market structure in Taiwan. Programming diversity was measured by 3 methods using program data from the 3 networks operating in Taiwan: vertical programming diversity, horizontal programming diversity, and prime-time programming strategies. The results indicate a negative relation between market competition and programming diversity. Although the market competition increased from 1986 to 1996, this study discovered that the degree of programming diversity was reduced year by year.  相似文献

This paper deals with automating the drawing of subway maps. There are two features of schematic subway maps that make them different from drawings of other networks such as flow charts or organigrams. First, most schematic subway maps use not only horizontal and vertical lines, but also diagonals. This gives more flexibility in the layout process, but it also makes the problem provably hard. Second, a subway map represents a network whose components have geographic locations that are roughly known to the users of such a map. This knowledge must be respected during the search for a clear layout of the network. For the sake of visual clarity the underlying geography may be distorted, but it must not be given up, otherwise map users will be hopelessly confused. In this paper we first give a rather generally accepted list of rules that should be adhered to by a good subway map. Next we survey three recent methods for drawing subway maps, analyze their performance with respect to the above rules, and compare the resulting maps among each other and to official subway maps drawn by graphic designers. We then focus on one of the methods, which is based on mixed-integer linear programming, a widely-used global optimization technique. This method guarantees to find a drawing that fulfills a subset of the above-mentioned rules (if such a drawing exists) and optimizes a weighted sum of costs that correspond to the remaining rules. The method can draw even large subway networks such as the London Underground in an aesthetically pleasing manner, similar to maps made by professional graphic designers. If station labels are included in the optimization process, so far only medium-size networks can be drawn. Finally we give evidence why drawing good subway maps is difficult (even without labels).  相似文献

Sharing of knowledge, information, and practices across cultural and national boundaries has become a means to address critical global problems. As government agencies increasingly collaborate with international counterparts on these issues, transnational knowledge and information sharing networks grow in importance as mechanisms for collaboration. This paper explores the nature of transnational public sector knowledge networks (TPSKNs) and identifies critical contextual factors that shape their performance. In these networks, each participating organization operates within complex national, organizational, and information contexts. The contextual differences between participants produce distances in culture, politics, intentions, organizational factors, relationships, knowledge, resources, geography, and technology. These distances influence their ability to engage in the processes and interactions that are essential to network performance. The paper concludes with a conceptual dynamic model that accounts for the relationships among these factors that can guide further research in understanding knowledge and information sharing across national and cultural boundaries.  相似文献

This study analyzes the particularities of Brazilian radio networks that adopt the all-news format and briefly presents the main national and international experiences for the implementation of the model and its conceptualization. Besides the bibliographic review, we use the multiple-case study, analyzing as the empirical objects CBN and BandNews FM networks. Also, we apply methodological procedures of systematic non-participant observation, supplemented by interviews and surveys. We conclude that the different all-news programming models and network organizations influence the processes of production, information structure, broadcasting language, and therefore the stations' profile.  相似文献

Product competition for news viewers in the cable national all-news market was examined. As the cable news networks do not directly compete with each other on price to consumers, it was expected that they would compete for audience by differentiating programming. A content analysis identifies program differentiation among the competing cable all-news networks. Each offered a distinctive style of programming. The different program formats and substantive content in each have the effect of counterprogramming, giving viewers a choice.  相似文献

The Internet began as a modest research experiment to link three early packet networks in an open-architecture framework. In due course, many other networks were connected, thus spawning a revolution in networking that continues to this day The early technology considerations inevitably led to social, administrative and commercial issues, and ultimately to political and societal issues as it spread worldwide. Today, the Internet is rapidly becoming a global information system in which all kinds of information can be accessed from virtually anywhere. The long-term ramifications of this rapidly evolving phenomenon are as unpredictable as that of society itself.  相似文献

In this article, I describe the contours of global media networks in terms of interorganizational linkages and spatial distribution of foreign direct investment in the entertainment industry. The results of multidimensional scaling revealed that there were significant differences in the positional structures of global networks in the entertainment industry. However, in the case of the structural relations between the interorganizational and geographical dispersion networks, the quadratic assignment procedure analyses revealed structural similarities between both networks in the entertainment industry. A multiple regression analysis also showed music and film industries played a significant role in explaining interorganizational and geographical dispersion networks. The findings indicate the benefit of distinguishing between interorganizational and geographic dispersion networks in understanding global media networks.  相似文献

The author investigates theoretical conditions under which vertical integration between a retailer (such as a cable television system, newspaper, or movie theater) with local monopoly power and the upstream supplier of one of the products it offers (such as cable television programming networks, newspaper editorials, or motion pictures) might induce the retailer to alter the prices or the content of its menu. The author then models the relationship between information product retailers and suppliers and shows that integration results in a lower retail price for the vertically affiliated product than for the unaffiliated product.  相似文献

ABSTRACT

Ethnocentrism affects perception and choices, and scholars, teachers, and students may not see or seek the “global” in our “global information revolution,” especially in such vast monolingual social spaces as the United States and the Anglophone world. Russia illuminates how unfortunate this state of affairs is because perceptions of Russia are so negative; whereas online information and open access there are so plentiful. Elibrary.ru offers free, full-text access to Russia’s periodical scholarship in all disciplines. Postnauka.ru is a lecture platform for Russian academics that rivals TED Talks in scale and production quality. Kul’tura is a federal television channel devoted entirely to education. Academic talk shows constitute part of the programming there and elsewhere. High-quality and reliable online tools such as these can enhance “Western” scholars’ and educators’ resource repertoires.  相似文献
