Taiwan has made significant progress in the semiconductor industry with government agencies and bureaucrats as the driving forces over the past 30 years. Taiwan's impressive achievement in the semiconductor industry clearly indicates that the government failures and agency problem usually associated with deep government involvement did not occur in Taiwan. Why is that the case? This paper proposes a principal-agent framework for technology policy and applies the framework to discuss the institutional arrangements through which bureaucrats were controlled effectively in executing the semiconductor industry policies in Taiwan. By analyzing the institutional and organizational arrangements Taiwanese leaders made to mitigate the agency problem, this paper brings bureaucrats into the popular developmental state theory and emphasizes that the success of state intervention should not be taken for granted, and it also brings politics into technology policy analysis and stresses the importance and complexity of agency problem in technology policy. 相似文献

This article presents data collected at the level of practice to highlight one non-governmental organization's approach to human rights education and how household-, school-, and community-level factors mediated student impact. Findings suggest that a variety of factors at the three levels contribute to the program's successful implementation in government schools serving marginalized students (where most HRE programs are in operation in India today). These responses emerge along a continuum from ‘time pass’—a commonly used term in India for anything that does not directly contribute to greater performance on high-stakes exams—to ‘transformative force’, wherein students internalize knowledge and values related to human rights and take action based on it. Responses to HRE were characterized in four areas and representative examples are provided of each: (1) personal changes; (2) attempts to intervene in situations of abuse; (3) reporting (or threatening to report) abuse; and (4) spreading awareness about human rights. 相似文献

This article discusses the results of a large-scale Internet survey (with 1156 respondents) that investigated the cues and factors that could positively influence Dutch Internet users' trust in government organizations in terms of their usage and processing of citizens' personal data. Confidence in online privacy statements, as indicated by the results of this study, significantly influences trust in government organizations among Dutch Internet users with and without previous e-government experience. Among those with e-government experience, the quality of their online government transaction experience and a positive government organizational reputation can also increase their trust in government organizations, specifically in terms of how they process and use citizens' personal data. 相似文献

There have been ample suggestions in the literature that terms added to documents from Flickr and Wikipedia can complement traditional methods of indexing and controlled vocabularies. At the same time, adding new metadata to existing metadata objects may not always add value to those objects. The potential added-value of using user-contributed (“social”) terms from Flickr and the English Wikipedia in image indexing is compared with using two expert-created controlled vocabularies—the Thesaurus for Graphic Materials and the Library of Congress Subject Headings—without those social terms. Experiments confirmed that the social terms did add value, relative to terms from the controlled vocabularies. The median rating for the usefulness of social terms was significantly higher than the baseline rating, but was lower than the ratings for the terms from the Thesaurus for Graphic Materials and the Library of Congress Subject Headings. Furthermore, complementing the controlled vocabulary terms with social terms more than doubled the average coverage of participants' terms for a photograph. The relationships between user demographics and users' perceptions of the value of terms were also investigated, as well as the relationships between user demographics and indexing quality, as measured by the number of terms participants assigned to a photograph. Participants with more tagging and indexing experience assigned a greater number of tags than did other participants. 相似文献

While many studies have discussed the impacts of electronic government (e-government) on public libraries, little research has considered the extent to which the current federal government's implementation of e-government relies on the public technology access, training, and support provided by public libraries. A range of data and policy materials are drawn upon in order to illuminate the co-evolution of public libraries and e-government. Beginning with a discussion of the development of e-government and its impacts in public libraries, the access, goals, and challenges of e-government are detailed as they relate to libraries, and the areas in which current implementations of e-government would not be possible without public libraries. Based on the explorations of the co-evolution of e-government and public libraries, key policy issues are offered that require reconceptualization in order to better support the interrelationship between e-government and public libraries. 相似文献

One of the first things Patrick Geddes did on taking up the post of Professor of Botany at University College, Dundee was to establish a botanical museum. Throughout his life museums were of great importance to him, and were central to his theories as an educationalist. The Outlook Tower in Edinburgh was the most famous demonstration of these theories, but this short introductory paper also looks at less well known aspects of them, such as his ground-breaking paper to the Museums Association conference in Dundee in 1907, his unpublished book.

Projective synchronization is a type of chaos synchronization where the response system states are scaled replicas of the drive system states. This paper deals with the propagation of projective synchronization in a series connection of N chaotic discrete-time drive systems and N response systems. By exploiting an observer-based approach, the paper demonstrates that dead-beat projective synchronization (i.e., exact synchronization in finite time for any scaling factor) is achieved between the nth drive and nth response systems. In particular, it is shown that projective synchronization starts from the innermost (Nth) drive-response system pair and propagates toward the outermost (first) drive-response system pair. Only a single scalar synchronizing signal connects the cascaded drive and response systems. Finally, an example illustrates the propagation of different types of chaos synchronization in a series connection consisting of a Gingerbreadman map, a third order hyperchaotic Henon map and a Lozi map. 相似文献

Organic synthesis of natural products began in 1828 with Wohler's synthesis of urea, the first time a substance derived from a living organism had been produced by combining inorganic materials. Progress in the field was slow at first, due to the limited purification and analytical methods. Advances in those areas gave rise to rapid progress in synthesis, as chemists could now focus their energies on devising new approaches to the preparation of increasingly complex molecules. While it is possible to prepare many molecules by using known chemistry in new combinations, real progress has been the result of keen insight and creativity on the part of only a few individuals.Professor Samuel J. Danishefsky established himself early on as a leader in this field when he recognized that a well-known ring forming reaction could be greatly extended by adding chemical functionality to one of the components. He then found that these new reactive components could react with heretofore unreactive components to produce new rings containing oxygen atoms both in the ring and as attachments to the ring. These products were very similar to naturally occurring sugars. Danishefsky realized that he could develop this chemistry further to produce precisely defined polysaccharides as well. Some of these polysaccharides occur on the surface of cancer cells. Using the chemistry he developed, he was able to prepare these cancer cell markers, and after combining them with certain proteins, showed that the resulting molecules behaved as cancer vaccines. Several have entered clinical trial.Danishefsky has synthesized many other natural products, but he is particularly interested in those that may be useful in treating cancer. His syntheses allow for the modification of the final product in ways that improve both safety and efficacy. Several of these compounds have also entered clinical trials. Thus his work has not only advanced the art and science of organic synthesis, but stands to make dramatic advances in the treatment of cancer as well. 相似文献
