Test excavations were conducted at Risco de los Indios (RDLI), a site at 2480 masl with 29 residential features and a well-developed midden containing abundant floral, faunal, lithic, and ceramic materials. Analyses indicate the site was intensively used ca. 500 cal b.p. as a residential base for groups focused on hunting guanaco, supplemented by locally-available wild flora and fauna as well as domestic beans transported from the lowlands. Ceramic and obsidian artifacts indicate these groups were highly mobile and in contact with groups on the eastern and western margins of the Andes. These patterns compare favorably to those seen in the region’s other high altitude villages. It appears that the development of these patterns began with population increase and economic intensification in the lowlands ca. 2000 cal b.p. and that the move to slightly lower elevation settings like RDLI may have been conditioned by the onset of the Little Ice Age. 相似文献

This article studies gender education gaps among indigenous and non‐indigenous groups in Bolivia. Using the National Census of Population and Housing 2012 and an estimation method analogous to difference‐in‐differences, the study finds that the intersection of gender and indigenous identity confers cumulative disadvantage for indigenous women in literacy, years of schooling and primary and secondary school completion. While gender education gaps have become narrower across generations, there remain significant differences within indigenous groups. The Aymara have the largest gender gap in all outcomes, despite having high overall attainment rates and mostly residing in urban centres with greater physical access to schools. The Quechua have relatively smaller gender gaps, but these are accompanied by lower attainment levels. The article discusses the possible sources of these differentials and highlights the importance of taking gender dynamics within each indigenous group into greater consideration. 相似文献

Is it possible for an anthropologist to decide whether an individual or a collectivity can or cannot be characterized as « indigenous », and then proceed to establish the limits of the territory which should be assigned (or recognized) by the state? Does his role as a scientist furnish him with the conceptual and methodological instruments necessary for such a task? In epistemological and ethical terms, is this something which he should endeavour to do? The purpose of this paper is to discuss how these questions are being put to Brazilian anthropologists since the 1980s. Torn between an « indianist » and an « indigenist » discourse, between romanticism and political mediation, the anthropologist must define an appropriate posture for dealing with policy-making; one which will simultaneously safeguard the scientific quality of his work while addressing the specific demands of each situation. 相似文献

The application of solid state electrochemistry techniques for the characterization and dating of leaded bronze objects is described. Characteristic voltammetric signatures of copper and lead corrosion products were used as markers of more or less prolonged corrosion periods. The proposed methodology was applied to samples from the Roman archaeological sites of Valeria (Spain) and Gadara (Jordan), Roman and medieval sites in Xàtiva (Spain), and modern statuary exhibited outdoors, on the campus of the Universitat Politècnica of Valencia, Spain, covering a time interval between the fourth to second century bc and the 20th century ad . For such samples, the ratio between the signals for copper and lead corrosion products decreased monotonically with the corrosion time. This variation was modelled on the basis of thermochemical and kinetic considerations, the experimental data being consistent with a potential rate law for the corrosion process. 相似文献

ABSTRACT Standard models of the new economic geography predict that costs of living are lower in the core than in the periphery. But in reality they tend to be higher in agglomeration areas, mainly because of regional differences in housing costs. In this paper, we add a home goods sector to the seminal NEG model of Krugman (1991) . We show that a core–periphery structure can endogenously emerge in which the core is the more expensive area. This result has an important normative implication. Since higher costs of living imply falling real wages if there is no nominal wage premium, it is not desirable for everybody to live in the core region. 相似文献

In a world in growing turbulence, complexity and uncertainty, where crisis is becoming the norm rather than the exception, resilience is increasingly seen as a critical feature that reflects the capacity of a system to absorb disturbance and reorganize without collapsing. Resilient systems are more adaptable to change, are more able to learn and are less vulnerable to disturbance and external shocks (e.g. natural phenomena, economic crises or political shifts). The resilience theories are re-emerging as a field of research and practice with application to socio-ecological systems, fostering new insights in the discussions about sustainable development. The main purpose of this paper is to explore resilience as a concept and as a framework for promoting more sustainable trajectories, highlighting its potentialities and advantages for policy and planning processes. SPARK, or the strategic planning approach for resilience keeping is introduced in the paper as a new sustainability framework, following key underlying concepts and seven key principles that capture the essence of resilience theories. The paper advances a methodological concept proposal for resilience assessment and planning that aims to contribute to linking theory and practice, performing knowledge brokerage and enhancing policy learning. 相似文献

DO FLOODS HAVE PERMANENT EFFECTS? EVIDENCE FROM THE NETHERLANDS 总被引:1,自引:0,他引:1

This study investigates the short‐ and long‐run impact on population dynamics of the major flood in the Netherlands in 1953. A dynamic difference‐in‐differences analysis reveals that the flood had an immediate negative impact on population growth, but limited long‐term effects. In contrast, the resulting flood protection program (Deltaworks), had a persisting positive effect on population growth. As a result, there has been an increase in population in flood‐prone areas. Our results suggest a moral hazard effect of flood mitigation leading to more people locating in flood‐prone areas, increasing potential disaster costs. 相似文献
