Weak Ties and Expertise: Crossing Technological Boundaries

In this article, we question how new technological traits can penetrate cohesive social groups and spread. Based on ethnographic narratives and following studies in sociology, the hypothesis is that not only weak ties are important for linking otherwise unconnected groups and introducing new techniques but also that expertise is required. In order to test this hypothesis, we carried out a set of field experiments in northern India where the kiln has been adopted recently. Our goal was to measure the degree of expertise of the potters distributed between early and late adopters of the kiln. Our results are discussed in the light of oral interviews. Our conclusions suggest that expertise is a necessary, albeit not sufficient, condition for weak ties to act as bridges and thereby for new techniques to spread. As an example, they explain how turntables could have been adopted by potters from the northern Levant during the third millennium BC.     

The Stone Tidal Fish Weirs of the Molène Archipelago,Iroise Sea,Brittany, Western France: a long‐term tradition with early megalithic origins

This reports on a project that combined evidence gleaned from aerial photographs, place‐names, interviews, topography, LIDAR data, and sonar bathymetry to locate stone tidal fish weirs in the Molène Archipelago. The results were verified by diver and pedestrian visual surveys. Models of Holocene sea‐level change allowed a group of possibly Late Mesolithic–Early Neolithic weirs to be recognized, with a second group broadly dated to the later Neolithic–Early Bronze Age. The construction of these long megalithic structures is compared to the funerary monuments for which the Molène Archipelago is well known, in terms of technique, cost, and societal organization.     

再论棺衽与小腰

棺衽作为先秦时期棺束的重要组成部分,通常被认为是小腰,也就是榫卯结构中的蝴蝶榫。该文综合文献与考古发现,认为两者非同一种器物。棺衽是麻绳棺束交叉处绕绳系结的结构,小腰是榫卯结构中的蝴蝶榫。考古发现中出土较多的类小腰器物应为绞具或绳扣。

The Political Ecology of Transition in Cambodia 1989–1999: War,Peace and Forest Exploitation

Over the last decade, forests have played an important role in the transition from war to peace in Cambodia. Forest exploitation financed the continuation of war beyond the Cold War and regional dynamics, yet it also stimulated co‐operation between conflicting parties. Timber represented a key stake in the rapacious transition from the (benign) socialism of the post‐Khmer Rouge period to (exclusionary) capitalism, thereby becoming the most politicized resource of a reconstruction process that has failed to be either as green or as democratic as the international community had hoped. This article explores the social networks and power politics shaping forest exploitation, with the aim of casting light on the politics of transition. It also scrutinizes the unintended consequences of the international community’s discourse of democracy, good governance, and sustainable development on forest access rights. The commodification of Cambodian forests is interpreted as a process of transforming nature into money through a political ecology of transition that legitimates an exclusionary form of capitalism.     

Spatial Analysis of Employment and Population Density: The Case of the Agglomeration of Dijon 1999

The aim of this paper is to analyze the intraurban spatial distributions of population and employment in the agglomeration of Dijon (regional capital of Burgundy, France). We study whether this agglomeration has followed the general tendency of job decentralization observed in most urban areas or whether it is still characterized by a monocentric pattern. To that purpose, we use a sample of 136 observations at the communal and at the IRIS (infraurban statistical area) levels with 1999 census data and the employment database SIRENE (INSEE). First, we study the spatial pattern of total employment and employment density using exploratory spatial data analysis. Apart from the CBD, few IRIS are found to be statistically significant, a result contrasting with those found using standard methods of subcenter identification with employment cut‐offs. Next, in order to examine the spatial distribution of residential population density, we estimate and compare different specifications: exponential negative, spline‐exponential, and multicentric density functions. Moreover, spatial autocorrelation, spatial heterogeneity, and outliers are controlled for by using the appropriate maximum likelihood, generalized method of moments, and Bayesian spatial econometric techniques. Our results highlight again the monocentric character of the agglomeration of Dijon.     

Regional planning of R&D and science–technology interactions in Andalucia: a bibliometric analysis of patent documents

Andalucia is a southern European LFR (less‐favoured region) with a high degree of self‐government that has allowed it to design its own R&D policies that complement those implemented throughout Spain and the European Union (EU). Recently the Regional Government passed the Third Andalucian Research Plan 2000–2003, an R&D planning instrument that, as has become customary in previous Plans, attributes considerable budgetary weight to the scientific aspects of the science–technology–industry system (Andalucia allocates more of its own resources to promoting research than any other region in Spain). This paper provides deeper insight into the role played by science in driving the technological development of Andalucia, one of the LFRs of the EU. The aim was to answer five fundamental questions: How is basic science utilized by industry in Andalucia? Which sectors are the most dynamic in the employment of scientific know‐how? Which scientific fields are most in demand by industry? Which types of institution utilize scientific knowledge most profusely? What delay is there in incorporating science into technology? The methodology that has been applied for investigating the links between science and technology is based on scientific citations in patent documents (NPC). The results in this article provide relevant information about the interconnection of scientific and technological systems and thus constitute a good point of reference for the development of future R&D plans.     

三国时期的薄葬风俗述论

丧葬的厚与薄同伦理道德、政治经济状况、社会舆论、政府导向等因素密切相关。三国时期,丧葬风俗由两汉时的多为奢侈转为力求薄葬,具有范围广、已形成于律令、丧制、墓葬规制与明器皆有明显变化等鲜明的特点。经济的凋敝、老庄思想的流行以及对盗墓的恐惧是产生这种变化的主要原因。
