While recent research on temporary clusters and temporary markets has emphasized the knowledge generation processes associated with trade fairs, little is known about the knowledge exchanges that are embedded in market relations at these events. This paper uses the case of the Canton Fair in Guangzhou, the largest trade fair in China, to illustrate that such events do not operate as a single market, but that they generate multiple dynamic market configurations, which entail different flows of knowledge, goods and people. In a typical case study, four types of market configurations are identified that simultaneously develop at this event. The findings contribute to a more comprehensive understanding of the dynamics of market relations, knowledge and transactions in temporary spatial settings.  相似文献

Capacity design aims to ensure controlled ductile response of structures when subjected to earthquakes. This article investigates the performance of existing capacity design equations for reinforced concrete coupled walls and then proposes a new simplified capacity design method based on state-of-the-art knowledge. The new method is verified through a case study in which a set of 15 coupled walls are subject to nonlinear time-history analyses. The article includes examination of the maximum shear force in individual walls in relation to the total maximum shear force in the coupled wall system, and subsequently provides recommendations for design.  相似文献

This article presents a numerical study on the force-deformation behavior of masonry spandrels supported on arches which are analyzed using simplified micro models. The model is validated against results from quasi-static cyclic tests on masonry spandrels. A large range of spandrels with different arch geometries, material properties, and axial load ratios are studied. The numerical results are compared to peak strength values predicted with an existing mechanical model. Finally, estimates for the initial stiffness and the spandrel rotation associated with the onset of strength degradation are derived.  相似文献

Abstract: Germany's new immigration law, which took effect in 2005, was hotly debated over a period of four years. This paper follows the debate on the law through the newsprint media, examines the representation of immigration as an economic utility, and investigates the contents of this economic‐utility perspective of immigration in light of neoliberal restructuring in Germany. The analysis focuses on 609 articles sampled from five major German daily newspapers published between July 2001 and August 2005. A discourse analysis suggests that the newsprint media represented immigration on the one hand as an economic necessity to replenish the labor market and ensure the international competitiveness of key industrial sectors. On the other hand, immigration was depicted as an economic liability that raises unemployment rates and burdens the public welfare system. Although the media emphasized the economic necessity of immigration, the final law does not permit any significant immigration of labor. The paper resolves this contradiction by situating media discourse in a wider context of neoliberal reforms and European Union expansion.  相似文献

"Brain Abuse", or the Devaluation of Immigrant Labour in Canada   总被引:1,自引:0,他引:1  
Harald Bauder 《对极》2003,35(4):699-717
Many professional and skilled Canadian immigrants suffer from de-skilling and the nonrecognition of their foreign credentials. Consequently, they are underrepresented in the upper segments of the Canadian labour market. Rather than accepting this devaluation of immigrant labour as a naturally occurring adjustment period, I suggest that regulatory institutions actively exclude immigrants from the upper segments of the labour market. In particular, professional associations and employers give preference to Canadian-born and educated workers and deny immigrants access to the most highly desired occupations.
Pierre Bourdieu's notion of institutionalised cultural capital and his views of the educational system as a site of social reproduction provide the entry point for my theoretical argument. I find that the nonrecognition of foreign credentials and dismissal of foreign work experience systematically excludes immigrant workers from the upper segments of the labour market. This finding is based on data from interviews with institutional administrators and employers in Greater Vancouver who service or employ immigrants from South Asia and the former Yugoslavia.  相似文献

Toward a relational economic geography   总被引:10,自引:0,他引:10  
In this paper, we argue that a paradigmatic shift is occurringin economic geography toward a relational economic geography.This rests on three propositions. First, from a structural perspectiveeconomic actors are situated in contexts of social and institutionalrelations. Second, in dynamic perspective economic processesare path-dependent, constrained by history. Third, economicprocesses are contingent in that the agents' strategies andactions are open-ended. Drawing on Storper's holy trinity, wedefine four ions as the basis for analysis in economic geography:organization, evolution, innovation, and interaction. Therein,we employ a particular spatial perspective of economic processesusing a geographical lens.  相似文献

The Corded Ware is one of the major archaeological traditions of Late Neolithic Europe. Its burial customs are characterized by single graves but multiple burials also occur. We present a detailed study of antemortem and perimortem trauma in a group of Corded Ware skeletons from four multiple graves and give the most probable interpretation of the site, based upon all available bioarchaeological evidence. The pattern of observed injuries in male, female, and subadult skeletons, including cranial trauma, arrow wounds, and fractures of the forearm and hands points towards a violent event that resulted in the death of all individuals, most probably a raid. In contrast to comparable Neolithic raid sites, there was no complete extermination of the local population and no use of mass graves. The burials have been arranged with care and detailed knowledge about biological kinship ties [Haak, W., Brandt, G., de Jong, H.N., Meyer, C., Ganslmeier, R., Heyd, V., Hawkesworth, C., Pike, A.W.G., Meller, H., Alt, K.W., 2008. Ancient DNA, strontium isotopes, and osteological analyses shed light on social and kinship organization of the Later Stone Age. Proceedings of the National Academy of Sciences of the United States of America 105, 18226–18231]. The combination of clear causes of death and the proven biological relationships among some of the individuals, including a nuclear family, provides new and important insights into Corded Ware mortuary customs and the reasons why and how multiple graves have been utilised.  相似文献

Slag inclusions are found within most archaeological bloomery iron artefacts and are remainders of slag created during the smelting and smithing processes. Although they are widely believed to provide data with the potential for provenancing iron artefacts, previous slag inclusion studies have mostly proven inconclusive. The main aim of the work reported here is to analyse experimental smelting and smithing assemblages (including ore, furnace lining, fuel and slag), to compare these to slag inclusions in the resulting bloom and worked objects, and then explore the relationships between ore, slag and slag inclusions. This study has revealed that the composition of slag inclusions most closely relates to the smelting slag produced, whereas provenance to a specific ore would be difficult due to the chemical variability derived from furnace lining, fuel and any fluxes used. Some compounds in the slag inclusions are particularly affected during smithing of the artefact, i.e. those present in the sand flux and fuel used. However, trends are observed in the K2O/MgO, MnO/SiO2, Al2O3/SiO2, Al2O3/MgO, Al2O3/K2O and Al2O3/CaO ratios that allow comparison between slag inclusions and smelting slag in these experiments, and may therefore be used during other provenancing attempts. The knowledge gained from the experimental assemblages was subsequently applied to an archaeological case study, examining objects from the 900 Cal BC smithing site of Tel Beth-Shemesh, Israel and the 930 Cal BC smelting site of Tell Hammeh, Jordan. The analyses suggest that none of the artefacts examined derived from the Hammeh smelting system.  相似文献
