东北地区资源性城市接续产业的选择

东北地区资源性城市接续产业的发展是东北老工业基地改造的重要内容之一。本文分析了东北地区资源性城市的发展历程和产业现状,指出了资源性城市接续产业发展的必要性和迫切性。然后,讨论了接续产业的选择依据。在此基础上,对东北地区资源性城市进行分类,并研究了不同类型资源性城市接续产业的选择。     

开封市产业空心化的历史考察

无论发达国家或是发展中国家,都会面临着产业空心化问题。通过对开封市经济数据的分析及实地调研,发现开封市的产业空心化属于离制造业现象:经济地位明显下降,固定资产日渐减少,工业发展缓慢且结构不尽合理,第三产业比重低且结构失衡。指出开封市产业空心化具有欠发达区的共性特征-贫困恶性循环积累性,同时也是其特定的区位条件所引致的。最后提出开封市产业空心化的防治措施:以增强技术创新为核心,进行体制机制、科研体制、教育制度创新及人才的激励机制等;以需求结构变化为导向,调整、优化产业结构,加强财政、金融改革及基础设施的支持力度;加速完善硬件设施,改变市区的对外联系等。     

珠海旅游产业集群的案例研究

在对旅游产业集群理论简要综述的基础上,文章以珠海市为案例,实地调研和深入访谈分析珠海旅游产业集群各要素之间的关系,并构建了珠海旅游产业集群的构成要素示意图,最后利用"钻石模型"评估珠海旅游集群的发展现状。文章充实了国内关于旅游产业集群的实证研究,指出珠海旅游产业集群已经初步形成,并且是一种政府主导型发展模式,但集群要素间进一步的知识和信息联系较少,创新性不足,珠海旅游产业集群属于低端集群,其进一步的完善和升级还需要继续发挥政府的支持和推动作用。     

Application of a new typological approach to classifying denticulate and notched tools: the study of two Mousterian lithic assemblages

Identifying tools by means of morphological attributes are widely used in lithic studies to categorize retouched artifacts from different archaeological periods. This procedure has facilitated the exchange of information between separate researchers and has improved the comparison of different assemblages. In these classifications, denticulates and notched tools have been regularly interpreted as analogues and chronologically unvaried in different and vast territories. Based on the definitions developed by Bordes, the denticulate category has become a catchall for any kind of tool bearing concavities. In this paper a new quantitative approach to the classification of denticulates and notched tools is proposed. The new methodology is based on measuring the length of notches and their distribution on the perimeter of the blank. Analyzing the lithic series of the Abric Romaní rock-shelter (Spain) and Grotta Maggiore di San Bernardino (Italy) led to the identification of 11 redundant forms: eight denticulates and three notched tools. Moreover, the application of Kuhn’s Geometric Index of Unifacial Reduction brought local manufacturing trends to light, calling into question the presumed geographical uniformity of these categories of artifacts.     

Worked Human Femur from Gohar Tepe,Iran

A simple tool made from a gracile human femoral shaft was retrieved from a small animal bone assemblage found in a Late Bronze Age stratum at Gohar Tepe, Iran. The specimen has been identified as a chisel or gouge for which no analogous examples are known in the Near East. Studies examining similar tools from other regions suggest that such a tool may have been used for wood processing or pottery smoothing. Copyright © 2012 John Wiley & Sons, Ltd.     

Participation in the reuse of industrial heritage sites: the case of Oberschöneweide,Berlin

In recent years, the significance of the debate concerning the participation of local communities in the reuse and management of industrial heritage sites has grown considerably. However, the question of how participation takes place in practice has received little attention. This article shows how participation in the reuse of industrial heritage sites has functioned in the planning process in Berlin-Oberschöneweide. The article is theoretically grounded on debates on labour and community heritage. The field of planning, which is closely interwoven with that of heritage management, provides another important theoretical horizon. The qualitative investigation consisted of interviews with different actors. The findings show that Oberschöneweide’s industrial heritage site is important to the local community. Thus far, the community has been able to participate in the reuse and development process in a number of ways. In addition to the provisions made for community participation by the relevant authorities, and local initiatives have exerted an influence on the development of the area. Nevertheless, this participation has been limited and is in some respects problematic. Furthermore, the participation process referred not only to the industrial zone itself, but to the development of the district as a whole.     

Molecular evidence of bitumen in the Mousterian lithic assemblage of Hummal (Central Syria)

Evidence for bitumen use in Middle Palaeolithic sites is an exception in Pleistocene archaeology. This paper presents the discovery of three tar-bearing Levallois artefacts found in the Mousterian sequence in Hummal (Central Syria). The organic residues were submitted to geochemical study. Gas chromatography–mass spectrometry analyses of saturated and aromatic hydrocarbons and isotopic data show the presence of bitumen. The most likely location of natural asphalt provisioning is the Shaaf outcrop in the Bichri desert. The bitumen-bearing stone tools add further important data to the growing knowledge about bitumen processing in the Middle Palaeolithic spring sites of El Kowm. Identification of the provisioning place for natural asphalt enables a more precise assumption about the site's catchment area. From a technological point of view, the tar-bearing specimens provide information on the range of tool forms selected for hafting. Ballistic features arguably indicate that the pointed Levallois blanks seem to be spear points that were fitted to a wooden handle. In at least one case, this technical procedure was seemingly executed during a brief episode of occupation and replacement of worn out implements. This small, bracketed window of detailed insight into Mousterian technology is linked with the more general relationship between Levallois technology and stone tool hafting.     

FRAGILITY OF STANDARD INDUSTRIAL STRUCTURES BY A RESPONSE SURFACE BASED METHOD

National and international regulatory standards require industrial risk assessment, taking into account natural hazards including earthquakes, in the framework of Quantitative Risk Analysis (QRA). Seismic fragility analysis of industrial components may be carried out similarly as what has been done for buildings, even though some peculiar aspects require the development of specific tools. In the present paper a contribution to the definition of a rational procedure for seismic vulnerability assessment of standardised industrial constructions in a probabilistic framework is given. The method covers a range of components of the same structural type. Seismic reliability formulation for structures is used. Both seismic capacity and demand are considered probabilistic with the latter assessed by dynamic analyses. The application example refers to shell elephant foot buckling of unanchored sliding tanks. A regression-based method is applied to relate fragility curves to parameters varying in the domain of variables for structural design.     

China's Economic Policy Today: The New State Activism

A noted American authority and investigator of China's economy outlines the general features of the ongoing reorientation of Chinese economic policymaking toward increased state activism, which has gained momentum in the aftermath of the global financial crisis. An initial section of the paper describes the marketization and privatization initiatives of China's late reform period to provide a baseline against which to measure the subsequent shift toward increased state intervention and guidance in the economy. The author traces the shift in three critical policy arenas (social policy, state-owned enterprises, and industrial and technology policy) and demonstrates how state involvement in each intensified during the global financial crisis. He then proceeds to explore the implications of accelerated state activism in the future, identifying potential rewards as well as large risks. Among the latter are macroeconomic imbalances, a "softening" of budget constraints, difficulties in recognizing and terminating unsuccessful economic programs, and tensions with trading partners.
