External Ties and the Reduction of Knowledge Asymmetries among Clusters within Global Value Chains: The Case of the Ceramic Tile District of Castellon

Classical industrial districts' literature is not focused on the role played by external ties but gives more importance to the local districts' endogenous development. Global value chains connect clusters to other external agents through external linkages and constitute a framework to analyse the complex inter-linkages between clusters and other external agents. In the field of the external ties and the global value chain approach Academia is primarily focused on the ties which link clusters in developing nations to global markets, although global value chains also consider connections between clusters in similar activities and even when both are located in developed nations. Thus, external linkages are mainly performed by multinational enterprise (MNE) affiliates which play fundamental role of knowledge diffusers and absorbers in the process of knowledge exchange throughout global value chains. The work examines the process of knowledge exchange between clusters through external ties using the global value chain approach. For this purpose, empirical work is conducted with 22 face-to-face interviews to provide a case study about a leading cluster in the global ceramic tile industry. Results show that the basic knowledge to successfully compete is locally originated, although it can be complemented with global knowledge learnt or generated in other territories. MNE affiliates bridge structural holes through external ties and reduce knowledge asymmetries within global value chains. External ties on network-based governance chains exist, matter and affect clusters allowing upgrading even between developed nations.     

高句丽将军坟的陪葬墓

将军坟是集安高句丽古墓中保存最好的一座大型方坛阶梯石室墓。多数学者认为它是高句丽第20代王长寿王的陵墓。将军坟后面原有一排陪葬墓,中外学者对其数量存在着分歧。1997年清理发掘后,有人认为第二座陪葬墓北侧的长方形石砌台基可能是祭台。通过古代墓祭的相关记载与考古迹象分析,应当是串形的陪葬墓。     

荥阳官庄遗址制陶作坊出土陶泥陶坯的科学分析

河南省荥阳官庄遗址发现了用于制陶的粘土原料以及未烧制的陶坯,这为研究西周中期以后中原制陶技术提供了不可多得的研究资料。为此,本研究利用能量色散X射线荧光光谱仪、X射线衍射分析仪分析了部分原料和陶坯,并使用马弗炉对其中的陶泥进行了烧制实验。结果发现,官庄遗址的制陶原料含铁量较高,烧制过程中析出磁铁矿等铁类矿物,且烧成陶色偏深;此外,制陶原料和同期陶片之间物相的趋同性和化学成分的聚类性,显示陶器本地生产的特性。研究结果为研究西周晚期至春秋早期时期制陶技术提供了基础材料。     

国内外旅游绅士化研究综述与展望

随着旅游发展与城市化进程的不断加快,旅游驱动下的绅士化现象日益显现,并受到国内外学者的关注。旅游绅士化现象不仅发生在城市区域,近年来旅游发展也推动了乡村地区的绅士化。旅游绅士化改变了特定区域社会结构、居民素养以及人居环境等,也改变了旅游发展格局,进而影响区域社会经济发展。从研究内容来看,国外相关研究主要聚焦在旅游绅士化的原因、过程和影响等领域,而国内研究主要集中在旅游绅士化的概念、类型、阶段、原因等方面。国内外已有研究较多关注旅游绅士化现象,研究方法较为单一,在旅游绅士化形成机理、旅游影响等方面缺乏深入系统的综合研究。通过丰富研究内容、完善研究方法、拓宽研究视角、夯实理论基础来构建研究体系是未来深化旅游绅士化研究的重要目标。     

洛阳新发现西汉画像砖

1996年洛阳市第二文物工作队征集一批汉画像砖.画像依题材分为10种,有车骑出行、山林狩猎、凤鸟与人物、兽斗、驯虎、龙、蟾蜍、玉兔、西王母等.画像砖时代为西汉晚期.这批汉画像砖的发现,为研究洛阳地区的汉画像砖艺术提供了新资料.     

欧阳修诗歌民俗描写的主观意绪

欧阳修诗歌中有许多对民俗现象的描写,特别是一些地方性特点很强的风习俗信,给他的作品增添了许多风采与蕴涵。作为诗家的欧阳修,他的民俗描写很显然并非简单地“观风”或“采风”,而往往与其创作之“思”密切联系着。也就是说,很多民俗事象是随着他的诗歌创作“感兴”而被带入作品的,这种“带入”自然渗透着诗家的主观意绪。本文即从诗人主观内涵与所写民俗现象之关系的角度进行梳理,以求教于诗学与民俗学界的同仁。     

关于会展业的发展条件及其动力体系的初步探讨

会展业是一个前期投入高,周期长的新兴产业,近年来,我国会展业也迅速发展,会展业的研究受到人们普遍关注。本首先分析发展会展业应该具备的基本条件,并根据这些条件与会展业的关联性提出了会展业发展的动力体系模式,章结尾运用这一模式对我国会展业进行分析,并提出我国发展会展业的一些对策。     

The archaeology and paleoenvironment of an Upper Pleistocene hyena den: An integrated approach

Data of high resolution for reconstructions of archaeological site formation processes can be obtained only by the use of precise excavation methods and comprehensive recovery techniques using fine-mesh water screening, followed by meticulous sorting and quantitative studies of all the small organic components from the screens. These methods are generally used at human occupation sites, but are not often employed at paleontological or mixed human-carnivore sites. At the site of Bois Roche, an Upper Pleistocene hyena den, we have used these meticulous recovery techniques in combination with absolute dating, geoarchaeological observations, taphonomic analyses, studies of microvertebrates and pollen analysis. Correlation of the site environmental data from pollen and microvertebrate assemblages with the vegetation record of a deep-sea core taken in the Bay of Biscay have allowed us to constrain the ages provided by ESR dating of bovid teeth and to reconstruct the physical environment of the site with a degree of confidence rarely achieved by the use of fossil remains from archaeological sites alone.     

中国村镇主体空间行为博弈及对策分析

我国进入快速城市化发展时期以来,在城市化和工业化的推动下,各类村镇主体的空间行为能力逐步增强,在其追求自身利益最大化的过程中,往往出现不理性的空间行为,在农村地区引发出诸多的空间问题。本文以各类村镇主体(农村居民、企业、农村基层自治组织、地方政府)的空间行为为研究对象,运用博弈理论深入分析各类不良空间行为产生的根源,有针对性地提出相关公共政策建议,以期改变其博弈规则,从而有效引导和规范各类村镇主体的空间行为,优化村镇空间。
