This paper examines the relationship between Schumpeterian patterns of innovation and the generation of breakthrough inventions. Our data source for breakthrough inventions is the “R&D 100 awards” competition organized each year by the magazine Research & Development. Since 1963, this magazine has been awarding this prize to 100 most technologically significant new products available for sale or licensing in the year preceding the judgment. We use USPTO patent data to measure the relevant dimensions of the technological regime prevailing in each sector and, on this basis, we provide a characterization of each sector in terms of the Schumpeter Mark I/Schumpeter Mark II archetypes. Our main finding is that breakthrough inventions are more likely to emerge in ‘turbulent’ Schumpeter Mark I type of contexts. 相似文献

ABSTRACTThe global financial crisis of 2007–08 and the subsequent Great Recession have pushed many economists to acknowledge a fundamental limit in the theoretical models elaborated after the monetarist counter-revolution: these models disregard the financial system. The years following the Great Recession have thus been marked by the development of what can be called the ‘Financial Frictions Approach’, a theoretical approach based on the addition of the financial system to the New Keynesian DSGE model. The results of this line of research are beginning to appear also in macroeconomics textbooks. Significant examples are the publication of the seventh edition of Blanchard’s textbook, and the publication of the third edition of the textbook co-authored by Blanchard, Amighini and Giavazzi. The objective of this work is twofold: (i) to show that the new model presented by Blanchard, Amighini and Giavazzi, which reflects the results of the ‘Financial Frictions Approach’, does not allow to elaborate a coherent explanation of the Great Recession and (ii) to present the pillars of an alternative theoretical model based on the lessons of Keynes, Schumpeter and Minsky. 相似文献

Since health tourism is one of the most popular and most dynamically developing products of modern tourism, this paper aims at studying the characteristic features of health tourism destinations from a regional and spatial perspective. Accordingly, the authors would like to introduce a new approach of spatial and product analysis of tourism where the market and spatial relations and relevance of health tourism were analysed through the example of Hungary. Although the classic medical tourism centres were established on natural medical water basis, by today, due to product diversification, continuous innovation and the involvement of medical services into health tourism, the geographical embeddedness seems to disappear, thus basically restructuring the market. The methodological novelty of the research is that exceeding the classic supply–demand algorithm, we compiled a complex viewpoint system adequate to the specialities of the given product characteristics. In our study, the authors intend to survey the special characteristics of health tourism focusing on medical destinations through Hungarian examples since the country's leading position in the global market is well recognized, including medical services.

By using Bourdieus’ thinking tools field, habitus and capital, this article first develops a concept of the journalistic field, in which economic capital and journalistic capital decide on (collective and individual) agents’ latitude and in which their autonomy could be influenced by economic logic, the discussion on journalistic norms and the logic of other social fields. Subsequently, this concept is implemented in a qualitative study. For that purpose 501 guideline interviews with journalists were conducted; they were asked about their career, their working conditions and their role perception. The findings show that in Germany nowadays the journalistic field is dominated by information professionals, who know their craft and who made the needs of the audience the benchmark of their work. Different from what literature suggests, it makes little sense to differentiate between a “commercial” and an “intellectual” pole. Exclusive news (which is what the field is all about) can only be produced where enough capital is available. At the centre of power, to which news magazines, national daily newspapers and public broadcasting stations belong, one can most easily withdraw from the economic logic and the influence that emanates from the audience and the advertising clients. 相似文献

Besides classical journalistic products, media users increasingly tend to read texts on the internet published by other users, as in weblogs. How do users navigate among these offers, how do they evaluate the quality, and which standards in terms of media ethics do they apply when reading weblogs compared to newspaper articles? Two empirical studies address these questions. In a survey, 702 internet users rated their theoretical expectations in terms of journalistic quality and compliance with ethical standards, comparing weblogs and daily newspapers. In a consecutive 2 × 2 experimental design, 120 participants read a journalistic text with varying source information (weblog/daily newspaper) and varying degree of adherence to ethical standards (ethically questionable/neutral). Participants then rated the quality of the text and its ethical standards. Results indicate that daily newspapers more than blogs are expected to deliver journalistic quality. But when read, texts are evaluated according to their content rather than their source. Ethically questionable texts in newspapers are disapproved as much as ethically questionable blog postings. 相似文献

To determine the various performance criteria concerning journalism it is reasonable to develop a broad concept, which integrates the different theoretical approaches. In a functional and system-oriented perspective, fundamental performance criteria can be based on the social function and the specific code of journalism, which emerged in an historical process of mutual observation of journalists and audiences. In a normative-democratic perspective, performance criteria can be derived from societal and human values codified in diverse regulations. However, in this regard it has to be taken into account that specific claims of the political subsystem also play an important role. Finally from an audience and action oriented viewpoint, it is important to keep in mind that journalistic communication must be useful and applicable in the world the audience lives in. 相似文献

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.

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
