生产范式变革下集群企业的去地方化研究

在全球化和地方化共同作用下,经济活动的去地方化现象越来越受到关注。与一般的产业转移概念不同,去地方化着重强调企业受到某种作用脱离地方生产网络,进而对地方生产网络产生的影响。目前关于去地方化的研究多集中在欧美国家,且多是基于全球生产网络的视角,而由企业生产范式变革引起的去地方化没有得到应有重视。实际上,在中国沿海地区,集群内创新型企业进行生产范式变革,引起企业去地方化现象十分明显,对地方经济社会产生深刻影响。在此背景下,本文建立生产范式变革、组织协同与企业去地方化的理论架构,分别以东莞鞋业集群和华宏鞋业公司为例,分析鞋业集群和企业在生产范式变革下的去地方化现象,为地方政府更好地制定实施集群政策和产业转移提供理论依据。

Faults and fault properties in hydrocarbon flow models

The petroleum industry uses subsurface flow models for two principal purposes: to model the flow of hydrocarbons into traps over geological time, and to simulate the production of hydrocarbon from reservoirs over periods of decades or less. Faults, which are three-dimensional volumes, are approximated in both modelling applications as planar membranes onto which predictions of the most important fault-related flow properties are mapped. Faults in porous clastic reservoirs are generally baffles or barriers to flow and the relevant flow properties are therefore very different to those which are important in conductive fracture flow systems. A critical review and discussion is offered on the work-flows used to predict and model capillary threshold pressure for exploration fault seal analysis and fault transmissibility multipliers for production simulation, and of the data from which the predictions derive. New flow simulation models confirm that failure of intra-reservoir sealing faults can occur during a reservoir depressurization via a water-drive mechanism, but contrary to anecdotal reports, published examples of production-induced seal failure are elusive. Ignoring the three-dimensional structure of fault zones can sometimes have a significant influence on production-related flow, and a series of models illustrating flow associated with relay zones are discussed.     

Iron age occupation in the Méma region,Mali

The recent archaeological campaign (regional site survey and excavations at the mound complex of Akumbu) has demonstrated that the Méma, a dry Sahelian region with a scattered population, was intensively occupied during the Iron Age. This intense occupation, certainly associated with better environmental conditions, extends back to the Late Stone Age. During the regional survey more than 100 Iron Age sites and nearly 30 Late Stone Age sites were identified; their size, surface material and features, and location on geomorphological zones were recorded. A series of radiocarbon dates spanning the fourth to fourteenth centuries ad obtained from the excavations at the Iron Age mound complex of Akumbu and a preliminary analysis of the pottery from both the excavations and the survey permitted the determination of a broad chronology of occupation. Numerous slag heaps (associated with smelting furnace remains) found during the survey and imported goods uncovered during the excavations at Akumbu indicate that both iron production and long-distance trade played an important role in the Méma economy.

Résumé Une campagne archéologique (reconnaissance et fouilles) exécutée en 1989–1990 a montré que le Méma, une région sahelienne de grande sécheresse à population actuellement éparse, était intensément peuplé pendant la période de l'Age du Fer. Cette intense occupation, certainement liée à de meilleures conditions climatiques, semble remonter à la période du néolithique. Au cours de la reconnaissance, conduite à l'échelle régionale, plus d'une centaine de sites datant de l'Age du Fer et environ une trentaine de sites néolithiques furent identifiés, enregistrés et décrits en termes de leurs dimensions, matériels et caractéristiques de surface, et environnement. Une série de datations au radiocarbone, obtenue lors de la fouille sur le complexe de buttes d'habitat de Akumbu, dans la partie ouest du Méma, indique une occupation s'étendant du quatrième siècle au quatorzième siècle de notre ère. La découverte d'imposants amas de scories, associés à des restes de hauts fourneaux, et objets exotiques trouvés lors des fouilles à Akumbu, attestent que la production de fer et le commerce à longue distance jouaient tous les deux un important rôle dans l'économie du Méma.

     

唐三彩的仪器中子活化分析其在两京地区发展轨迹的研究

本文采用仪器中子活化分析技术测定四个主要的唐三彩窑遗址(河南黄冶窑、陕西铜川黄堡窑、长安礼泉坊窑、河北邢窑)以及墓葬、建筑遗址出土唐三彩胎的元素组成,分辨了不同产地唐三彩胎的元素组成差别。而且,本文综合考古资料、实验数据的统计学处理结果,将唐三彩在盛唐时期的发展历程划分为两个阶段,大约以公元705年(武则天退位)为界。前一阶段的唐三彩属于白胎类型,制作中心集中在洛阳地区,唐三彩器主要由黄冶窑制造,大型唐三彩俑由洛阳地区(包括黄冶附近)未被发现的窑场制作。后一阶段唐三彩的制作中心向长安地区转移,该中心的重要产品是红胎唐三彩,同时可能采用外来的原料制作白胎唐三彩,洛阳地区作为唐三彩的另一个制作中心同时存在。进而论证唐三彩器和唐三彩俑存在两个相对独立的发展轨迹。     

社会空间视角下大遗址区乡村地域功能结构研究——以关中5处大遗址区为例

新时期国家大力推进遗产“活化”与遗产旅游,大遗址保护与利用过程既影响区域空间功能重构又涉及深刻的社会关系调整。研究选取大遗址数量多、分布密集的关中地区中5处大遗址区为案例,从社会与空间维度构建指标体系,采取因子生态分析划定社会区,以“社会—空间”综合交互视角解析乡村地域功能结构特征。研究发现大遗址区乡村社会空间存在文保限制因子、旅游带动因子、工业与商贸因子等8个主因子,各主因子空间分布体现典型的分异特征,并呈现出6种功能属性的片区。其地域功能结构特征表现为：①保护区划产生圈层式地域功能格局,②高附加值功能空间沿交通线嵌入,③核心与边缘区功能构成与遗址影响力及城乡区位相关,④各功能片区并未形成产业联动。在此基础上,进一步剖析了大遗址区乡村非均衡发展成因及优化路径。     

博物馆中的南海知识生产与地理想象

地理想象是通过文化媒介对特定地方的地理“现实”的转录与重构,而博物馆是达成地理想象的一个代表性媒介。博物馆不只是一个展品陈列的空间载体,其中还包含着地理知识的生产。本文以南海博物馆为例,采用参与式观察、半结构式访谈、话语分析方法,探讨中国（海南）南海博物馆对“南海”的呈现。研究表明,南海博物馆对南海的地理想象不仅是话语建构,同时也是一种国家领土主权在话语层面上的实践。地名、地物、地图、地景是南海地理想象的构建基础,中国（海南）南海博物馆通过对“过去”资源的空间组织,构建了“南海”的地域想象、边界想象以及地缘想象。     

Sustainable management of metallurgical forest on Mont Lozère (France) during the Early Middle Ages

Mont Lozère, located in the French Massif Central region, provides an exceptional context in which to research the impact that charcoal production and metallurgy had on woodlands, along with the role that these activities played in changing the mountain landscape. This study provides an insight into the land use, forest management methods and metallurgical practices in the area during the Middle Ages (11th to 15th centuries). Medieval charcoal burning platforms, archaeological remains that have often been neglected in the past as a source of historical information, along with nearby smelting sites, were identified, sampled and analysed. In this paper, spatial analyses, radiocarbon dating and anthracological and dendro-anthracological studies have been combined in a unique manner. The results reveal that charcoal burners practiced beech coppicing, where the species and diameter of wood used remained the same over a period of four centuries. It is proposed that this form of metallurgical forest management be considered an early example of a sustainable utilisation of natural resources.
