The objective of this research is to examine in depth the brokerage roles that supporting institutions play in conducting local business and applying technical knowledge inside clusters. We identify three main roles: a coordination role, characterized by the efforts that organizations play in internally coordinating themselves and establishing a shared institutional framework; an interconnector role, where organizations foster communication along the value chain of the industry; and a gatekeeper role that allows organizations to connect cluster members with external networks. Results obtained in the Toy Valley cluster provide evidence that each kind of supporting organization tends to specialize in specific roles, since universities are best for a coordination role with regard to technical knowledge while private organizations are key for vertical communication and coordination. Similar results were obtained when analysing the extra-cluster contacts that these organizations develop as gatekeepers, as they tend to establish specific communication conduits with similar alters in external networks.  相似文献

唐长安商业空间形态分析   总被引:2,自引:0,他引:2  
通过对长安城市外商业点空间分布、存在时间和经营业种的分析,重新认识长安城商业空间发展演变的特点。早期都城的商业空间形态呈封闭对称的双核心结构,中唐以后,随着城市经济的发展和居民生活的需要,商业点突破市坊限制,在朱雀街东以皇城景风门外诸坊和以东市为核心的部分坊里内相对集中分布,形成了以东市为核心的商业区,在朱雀街西则分布较少,在外城城关处仅有零星商业点的分布,没有形成综合性的商业功能空间。所以唐代中后期长安城商业空间形态表现为“一核、一区型”结构特征。  相似文献

Biogeographers, ecologists, palaeontologists, and conservation managers often deal with checklists in which not all individuals have been identified to a species level, or the accuracy of species identification is questionable. Is it possible and credible to investigate species richness based on such checklists? Studies on macrofauna in the Far Eastern seas, eastern Arctic seas, and adjacent waters of the Pacific and Arctic Oceans suggest that in different habitats and for diverse taxa, species, and higher taxa richness strongly correlate with each other and increase with an expansion in the study area and sample size according to the species–area law. Such an increase is higher in the bottom zone than in the pelagic. Species and higher taxa richness also show a decrease from lower to higher latitudes, which is in line with the Humboldt–Wallace’s law. According to Willis’ law and self-similarity in the organisation of taxonomic levels, species richness can be assessed based on the genus, family, and order richness. In other words, supraspecies richness itself can tell us the same as species richness and therefore certain global patterns revealed at the species level may also be revealed at the supraspecies level. Such a concordance in general trends among richness parameters at different taxonomic levels in practice implies that species richness can be studied based on lists that lack species identifications or lists with doubtful species identification. We suggest bolder use of supraspecies richness in science and practice, discussing the disadvantages and advantages of this approach.  相似文献

Abstract

This paper addresses questions of women’s visibility in constructed histories, as well as levels of recognition concerning their participation in politics through historical narratives. In particular, historical narratives representing women in protest in the context of waterfront heritage zones associated with the shipbuilding industry are examined, based on examples of two public art projects: Strong Women of the Clydeside: Protests and Suffragettes from Govan’s Hidden Histories led by the artist t s Beall in the Govan area of Glasgow, Scotland and Shipyard is a Woman by Arteria Association and Metropolitanka in Gdansk, Poland.  相似文献

Increasing interest in the Victorians' relationships with the material world has led many critics to turn to periodical publications and, in particular, to process articles and other forms of industrial writing as sources for new insight. This article contributes to this growing body of scholarship by examining narratives of doll production. Because dolls are objects that Victorians celebrated for their imaginative potential and that were often not intended to be treated as ordinary commodities, such narratives can shed light on the intricate relationships between materiality and the imagination. In revealing the process of production, these narratives deconstruct dolls, reducing them to a collection of material parts. By some accounts, these parts are brought to life through a specialized process of manufacture that dehumanizes the workers who make them and robs them of their imaginative agency. While this deconstructive exploration can be seen as an extension of the ‘melancholy and gloom’ that Baudelaire describes as the result of children's destructive compulsion to see the insides of their toys, it could also generate new imaginative possibilities. By inviting readers to behold commodities in a state of transformation, I argue, narratives of doll production demand a more imaginative attitude towards commodities as objects shaped by their material histories.  相似文献

This article concerns the cross-interaction problem among multi-foundations on a linearly viscoelastic medium at very small shear strains. In the analysis, the foundations are discretized into a number of sub square-elements. The dynamic response within each sub-element is described by the Green’s function, which is obtained by the Fourier-Bessel transform and the precise integration method. Incorporating the displacement boundary condition and the force equilibrium of the foundations, it obtains the dynamic impedance and compliance functions of the foundations. Extensive results for two rigid circular foundations placed at different separations are presented. Parametric studies are carried out on the dynamic interaction among adjacent foundations. Illustrative results for several closely spaced foundations are also illustrated.  相似文献

本文结合南北朝至隋末区域文化合流的背景,考察隋末唐初秦府集团成员的仕进状况,其中包括人才类型、家庭政治背景、个体政治势力来源、进入秦府的渠道、个体政治活动空间,认识了以李世民为核心的秦府政治集团,利用争夺天下之机,逐步拓展政治空间,将各地各类精英人才吸纳到秦府集团里来。在此过程中,李世民集团有意识地编织原北周、北齐、南陈入杨隋政治势力后裔,并用关陇、山东、江左这三大政治文化区域人才所长,将他们化入到同一个文化熔炉里融冶,大大推进了区域文化合流的步伐,在中华民族文化融合史上写下了崭新的篇章。  相似文献

Abstract

This article examines the lives and deaths of Yokogawa Shōzō and Oki Teisuke, two ‘shishi’ (men of high purpose), captured, court-martialled, and executed by the Russians shortly after the outbreak of the Russo-Japanese War in 1904. While their deaths apparently served little or no purpose, the tale of Yokogawa and Oki was presented to the public in three distinct fashions. The first was to a Western audience in newspaper reports at the time of the war. The second was the manner in which the Russians portrayed them for the home front during the war. Finally, there was the manner in which the pair was presented in a reader for young Japanese boys in the late 1920s. Each portrayal served a distinct purpose that this article will address.  相似文献

Henry Head, the English neurologist, received the main parts of his academic education in Cambridge and in London. In addition, he spent two years in Prague where he worked in the physiology department of the German university under the guidance of Ewald Hering. He was interested in the nervous control of breathing and worked out a new method of recording the tension and the contractions of the diaphragm in anaesthetised animals. His results substantiated the experimental basis of the Hering-Breuer reflexes and included the discovery of a new reflex now named Head’s paradoxical reflex. Head not only wrote an extensive paper about his scientific work, the recollections of his time in Prague also formed a considerable part of his autobiographical notes. These were written some forty years later and still expressed a deep affection for his teacher and mentor.  相似文献
