We review evidence from human biology—paleopathological and isotopic paleodietary studies on ancient Maya skeletons—to assess the validity of ecological models of the Classic Maya collapse, in which elevated disease and deteriorating diet are commonly assumed. To be upheld, the health arguments of ecological models require that the Maya disease burden (1) was greater than that for many other societies and (2) increased over the span of occupation. The dietary argument requires (1) consistent change in diet from Preclassic and Early Classic Periods to the Terminal Classic and (2) increasing social divergence in diet. A correlation between diet and disease is necessary to link these arguments. Neither pathology nor isotopic data consistently support these criteria. Instead, it appears that local environmental and political factors created diversity in both disease burden and diet. In view of the human biological data, we are skeptical of ecological models as generalized explanations for the abandonment of Classic Maya sites in the southern lowlands. 相似文献

AbstractThis article introduces a special issue on the emergent relationship between the rhetoric and implementation of the rule of law concept in Southeast Asia. It thematically introduces four country case studies (Cambodia, Myanmar, Thailand and Vietnam), and the case of ASEAN’s adoption of the rule of law in region-building, which are included in this special issue. We highlight how ideals that are arguably central to the “tradition” of the rule of law are being excised, marginalised, defended and/or undermined in Southeast Asian contexts. We emphasise how the very concept is deeply contested and far from neutral – at stake is the very notion of “law” for whom, and for what. The article offers insight into the social dynamics affecting how the rule of law is being interpreted by political actors and how it is being contested and consolidated via governance practices in the region, and proposes new avenues for research in assessing how the rule of law is operating in transitional and authoritarian state settings. 相似文献

This paper analyses the relationship between knowledge production and urban locations in industrial design, a knowledge-intensive business service (KIBS). KIBS concentrate in urban locations. This is often explained by the co-location of client firms and market access in large cities. Recent research on knowledge production, however, reveals that knowledge productive networks are significant for both the competitiveness and location of KIBS. Thus, to understand the urban location of industrial design, it is important to analyse how knowledge production is organized within the industry. Industrial design is concentrated in urban locations, but most of its clients are located elsewhere. Hence, it seems that industrial design firms concentrate in urban locations mainly because their knowledge networks include specific types of formal and informal local social networks. 相似文献
