台湾地区大学整并政策是在为了追求最佳规模效应,竞争有限的资源,调整大学结构,进而提高大学运作效率的初衷下出台的。台湾当局通过经费支持等措施推进大学整并工作的开展,并主要以校内整合与校际整合两种方式进行,以公立研究型大学为重点。但从其整并的实施来看,也存在着一些值得注意的问题,比如最适规模、特色化、机构认同等。 相似文献

For centuries, there have been discussions as to whether only experts can judge the quality of cultural output, or whether the taste of the public also has merit. This paper tries to answer that question empirically, using national finals of the Eurovision Song Contest. We show that experts are better judges of quality in the sense that the outcome of finals judged by experts is less sensitive to factors unrelated to quality than the outcome of finals judged by public opinion. Yet, experts are not perfect; their judgment does still depend on such factors. This is also the case in the European finals of the contest. 相似文献

目的观察火针治疗前后大鼠跟腱末端区细胞凋亡情况的变化,探讨火针治疗末端病的作用机理,为末端病的火针治疗提供理论依据。方法采用"电击跳跃法"建立大鼠跟腱末端病模型,施以火针治疗,采用TUNEL法检测细胞凋亡指数(AI)。结果(1)1次火针治疗后,治疗组大鼠末端区主要在跟腱、纤维软骨区、腱围这三个部位的AI比对照组有不同程度降低;(2)经4次火针治疗后,跟腱、纤维软骨区、腱骨关节面软骨、腱围的AI明显低于对照组;(3)4次火针治疗后在跟腱、纤维软骨区、腱骨关节面软骨、腱围的AI明显低于1次火针治疗组。结论(1)8周的"电击跳跃法"成功建立了大鼠跟腱末端病模型。(2)1次火针治疗可以减少末端区的细胞凋亡和修复已凋亡的细胞。(3)4次火针治疗不仅使末端区的凋亡细胞得到修复,而且加速了整个末端区组织和结构的恢复。 相似文献

Web 2.0 has had an impact on library web sites making them more interactive with users, giving rise to the term Library 2.0. What is meant by Web 2.0 tools is generally understood but the degree of implementation of these tools in libraries is largely unknown. This study reports on the implementation of these tools in national libraries all over the world in order to give an objective measure of the impact of Web 2.0 on library web sites. 相似文献

The implementation of E-government aims at simplifying and improving the transactions between public administrations and their users or customers. The objective of this study is to analyze whether the factors behind the level of development of E-government among municipalities of a specific country are common to the improvement of digital administration in the largest municipalities from 81 countries worldwide. While previous studies provide evidence that municipalities from the same country, mainly those governed by left-wing parties, focus on differentiating themselves in the content of their Web sites, our findings emphasize that internationally, in the most important municipalities worldwide, all the political parties attempt to promote the development of a dynamic and participatory E-government. 相似文献

The painting Proas Iluminadas (Illuminated Bows) by Benito Quinquela Martín is studied by Raman spectroscopy in order to analyse the technique and the pigments employed by the artist: ultramarine blue, carbon black, cadmium-sulphure based compounds for the hue of yellow, orange and red; also zinc white, barium yellow, massicot yellow and viridian were observed. The importance of using different excitation laser lines in the analysis of mixtures of pigments is highlighted. The Raman mapping analysis of cross section samples shows the way the artist composed the ground layer: a lead white stratum over a calcite one. It also allows distinguishing between a mixture of components and strata superposition, both presenting the same appearance under an optical microscope. This paper provides information about the materials and techniques used in a period of Argentine art not studied before from this point of view. 相似文献
