This is an account of planning a part-time Masters degree in Women's Studies at a British Polytechnic. We explain how we obtained approval from the necessary authorities for the course, and discuss the conflict between—on the one hand—the need to conform to these institutional procedures in order to get the course established, and—on the other hand—the desire to keep faith with the political origins of Women's Studies in the Women's Movement. We discuss a number of major issues which have confronted the members of the committee responsible for planning this course including the struggle to demonstrate within the college the academic legitimacy of WS; decisions about what kind of course to offer students—a multidisciplinary or interdisciplinary curriculum, with or without optional elements—and how to defend these proposals during the lengthy process of seeking formal approval; the institutional politics of launching the course; and anticipated problems associated with the eventual teaching of the course.  相似文献

This research explores probable budgetary consequences from the introduction of an institutional change which requires communities in metropolitan areas to pool any growth in the commercial-industrial tax base so that all cities benefit from new development irrespective of where the development occurs. Sharing of the tax base has been suggested as a means to overcome fiscal disparities among local governments in metropolitan areas and to reduce competition for new industrial development, thus, promoting ‘orderly development’ of the urban area. An alternative view of the institutional change focuses on the consequences of removing the tax base from the control of the local unit of government and suggests that based upon existing studies of government size and the cost of public services, government managers will be less responsive to the wishes of the citizen/taxpayer after the introduction of tax base sharing. The efficiency aspects of local government finance are examined and based upon data for the Minneapolis-St. Paul metropolitan area, the expenditure effects are estimated. The empirical evidence suggests that while revenue flows are altered in the metropolitan areas, the primary impact of tax base sharing has been to expand the level of government expenditures, not equalize interjurisdictional tax rates.  相似文献

Some analysts have argued that research links between universities and industry in Japan must be weak because Japanese universities do not produce high quality science and because regulations restrict links. This article begins by examining the structure and funding of universities and indicators of the performance of Japanese science. The results do not lend support to the view that the universities do not produce research useful to industry. In addition, the system is evolving in directions more favorable for university research excellence. Examining the regulations governing university-industry interaction, and their observance, reveals no insuperable barriers. Thus, it is not surprising that bibliometric indicators suggest Japanese companies collaborate with Japanese academics more than with foreign institutions. R & D managers describe long-lasting relationships with academics, perhaps originating in college days, which continue with mutual benefits and obligations on both sides and provide valuable access to the wider network of the scientific community-access that money alone cannot buy. The stories of individual research collaborations establish the substantive nature of the underlying work, the importance of experimentation performed on university instrumentation, and the crucial role of personnel exchange.  相似文献

This study involved the comparative analysis and discrimination of 90 electrical tape adhesives. The objectives included the evaluation of the ability of individual techniques to discriminate samples and the assessment of the ability of the techniques combined to distinguish samples. The techniques utilized were stereomicroscopy, Fourier transform infrared spectroscopy (FTIR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), and scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS). Stereomicroscopy, to assess adhesive colors of black, clear/colorless, and clear adhesives with brown tint, resulted in a discrimination of 53%. FTIR analysis yielded eight distinct groups with a discrimination of 67%. Py-GC/MS analysis resulted in 16 groups with a discrimination of 83%. These analyses confirmed and further subdivided the FTIR groups. SEM/EDS resulted in five separate groups at 17% discrimination, increasing the overall discrimination to above 85%.  相似文献

This study involved the comparative analysis and discrimination of 964 architectural paint samples collected in the United States and Canada. The samples were evaluated to determine the extent to which randomly collected architectural finishes can be discriminated following standard operating protocols for paint analysis. The study also provides a basis for assessing the significance of a result in which a pair or group are undifferentiated. The techniques utilized were stereomicroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) with both backscatter electron imaging (BSI) and energy dispersive spectroscopy (EDS), and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). To assess the layer characteristics (e.g., number, color, sequence, thickness), stereomicroscopy was used with FTIR and/or SEM as needed. The use of visual and microscopic evaluations in concert with FTIR resulted in 42 undifferentiated pairs, a discrimination of 99.99%. Adding SEM and Py-GC/MS analysis resulted in further discrimination of 31 pairs, resulting in eleven undiscriminated pairs of samples. At the conclusion of the study, samples that remained undifferentiated proved to originate from the same source. Therefore, no random pairs were indistinguishable at the conclusion of all examinations.  相似文献

Theorists often claim that being bigger than one's counterparts offers advantages in multilateral negotiations. In this article, I examine that argument using data from negotiations in the United Nations General Assembly (UNGA). The article analyzes and compares the activity levels of smaller and larger states in international negotiations, and sheds light on the conditions under which the latter “punch below their weight.” My analysis indicates that size directly affects participation, but not success rates. Bigger states can better formulate national positions on a broad range of issues, enabling their diplomats to more actively participate in negotiations, while smaller states are absent more often. Activity is conducive to success, which helps bigger states. But not every negotiation strategy is equally effective. In the UNGA's one‐state, one‐vote context, bigger states are not able to systematically exert disproportionate influence despite their often superior financial resources and bargaining strategies.  相似文献
