The brokerage role of supporting organizations inside clusters: how does it work?

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.     

唐长安商业空间形态分析

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。

What can supraspecies richness tell us?

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.     

俄罗斯远东“中国移民问题”论析

在俄罗斯远东乃至全俄罗斯,“中国移民问题”是一个被有关势力上升到政治层面加以夸大、炒作的敏感问题。其主要肇因既有历史基因的复萌,也有现实利益的驱动。在其影响下,中俄两国开展劳务合作的潜力远未得到应有的发挥。近年来,俄虽有部分学者和政界人士能较为客观地分析中国移民问题,阐述利用中国劳务的必要性,且积极探讨利用中国劳务的有效途径,但俄罗斯社会对中国人持有的戒备和排斥心理仍相当浓厚。对此,我们应多从自身方面找原因,改进做法,积极应对,促使俄罗斯社会改变对中国人的偏见,从而将远东变成中俄合作真正的窗口和桥梁。     

The Role of Russian Big Business in Local Development

The paper, based in part on field surveys in 2006, examines the role played by large Russian companies in local development, focusing on the operations of SUAL and Severstal' in Northwest Russia. The two companies provide examples of different models of corporate behavior (transnational and paternalist) in the current Russian business environment, reflecting a choice more broadly between neoliberal and corporate-nationalistic versions of Russia's participation in globalization. The author investigates the implications of the different models for the local jurisdictions in which these companies operate.

Possible evidence of mammoth hunting during the Epigravettian at Yudinovo, Russian Plain

Whether or not mammoth hunting was practised during the Late Palaeolithic has been a controversial issue ever since large accumulations of woolly mammoth bones associated with prehistoric artefacts were discovered more than 100 years ago. Detailed taphonomic and palaeobiological analyses of the mammoth bone complexes from the Epigravettian Yudinovo site in the Russian Plain were carried out. The combination of the homogeneous weathering rate of the mammoth bones, the isolated state of most of the skeletal elements, the restricted spatial range of the carnivore gnawing traces, the breakage pattern of the skulls and long bones, the sex ratio, the small body size of the adult mammoths, the age profile (with an important frequency of prime-aged cows), and the large number of individuals, suggest that the bone complexes at Yudinovo were constructed from body parts and bones that were extracted from freshly killed mammoths and that mammoth hunting was practised at this site during the Epigravettian.
