The western region of São Paulo state, Brazil, became one of several sites of global cotton production during the first half of the twentieth century in response to increased global demand and fears of cotton shortages. The cotton boom tapped a ‘forest rent’ that helped Brazil rise to become the largest producer in Latin America, providing both export revenue and critical raw material to a growing industrial economy that would become the largest in South America. This paper uses an organizational and institutional perspective to analyze causes and effects of the mid-century cotton boom that centered on São Paulo state. Organizations and institutions relating to cotton production are considered using oral histories, judicial documents, agronomic texts, and the sediment record in small catchments as empirical evidence. The state dramatically reformed some organizations to provide the key inputs to cotton production, while most contemporary observers ignored institutions, such as sharecropping and tenant farming, that supported cotton. São Paulo's institutions and organizations were characterized by the borrowing and adaptation of existing labor institutions, the creation of new state organizations that subsidized elite producers, and the weak development of institutions or organizations in response to soil fertility issues and labor supply. 相似文献

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。 相似文献

在当代世界各国的城市化进程中,城市的更新改造和发展以及相关问题和矛盾的解决都是要面临的重要课题。示范城市运动是美国大规模城市更新运动的重要阶段,也是轰轰烈烈的"伟大社会"改革中后期重要的战略转移。本文选取该项运动为研究主题,回顾了其发生背景、发展过程,分析了其正反两方面的经验,以期为中国在进入改革开放关键时期构建和谐社会进程中更好地解决城市问题提供一个有价值的参照。 相似文献

上海大都市区物联网产业集聚与空间演化 总被引:4,自引:0,他引:4
新兴技术产业的空间集聚与扩散对大都市区的空间结构有直接的影响,厘清新兴技术产业的空间分布和区位选择规律对新兴产业集群培育和大都市区空间结构调整都具有重要的政策意义。本文分析了上海市物联网企业的空间分布和集聚特征,结果发现初创期物联网企业在郊区集聚,随后向郊区其他区域扩散,并呈现出从单极向多极集聚转变的空间演化进程。通过构建负二项回归探究上海物联网企业的区位选择因素,结果表明制度因素和企业集聚效应对企业区位选择有重要影响。在产业发展初创期,企业区位选择受政府管制和市场机制双重影响,其中制度因素发挥了关键作用;而在随后的兴起期,产业集聚效应对新企业的入驻具有强大的吸引力。 相似文献

The modern project of rural development has been seen as one of increasing incorporation, control and rationalization of territory by the state. Evidence from the formulation of the Colombian land reform policy of 1961 gives more nuance to this general conceptualization. Those places where the state intervened through large‐scale resettlement programmes conceived within the framework of Cold War development are the same places where war and the drug economy — the most serious threats to the state itself — took root and grew. This article examines this contradiction. It interrogates the idea of modern development as a project that necessarily brings subjects and territories into the realm of state control. It also attempts to provide a counterweight to arguments about the territorialization of the war in Colombia being the outcome of state inaction and lack of development. 相似文献

The Corded Ware is one of the major archaeological traditions of Late Neolithic Europe. Its burial customs are characterized by single graves but multiple burials also occur. We present a detailed study of antemortem and perimortem trauma in a group of Corded Ware skeletons from four multiple graves and give the most probable interpretation of the site, based upon all available bioarchaeological evidence. The pattern of observed injuries in male, female, and subadult skeletons, including cranial trauma, arrow wounds, and fractures of the forearm and hands points towards a violent event that resulted in the death of all individuals, most probably a raid. In contrast to comparable Neolithic raid sites, there was no complete extermination of the local population and no use of mass graves. The burials have been arranged with care and detailed knowledge about biological kinship ties [Haak, W., Brandt, G., de Jong, H.N., Meyer, C., Ganslmeier, R., Heyd, V., Hawkesworth, C., Pike, A.W.G., Meller, H., Alt, K.W., 2008. Ancient DNA, strontium isotopes, and osteological analyses shed light on social and kinship organization of the Later Stone Age. Proceedings of the National Academy of Sciences of the United States of America 105, 18226–18231]. The combination of clear causes of death and the proven biological relationships among some of the individuals, including a nuclear family, provides new and important insights into Corded Ware mortuary customs and the reasons why and how multiple graves have been utilised. 相似文献

The Central Anatolian Volcanic Province (CAVP) in Turkey preserves widespread deposits of Quaternary tephra, presently associated with a small but growing number of Paleolithic archaeological sites. We use multivariate analyses of the abundances of a suite of nine major and minor element oxides determined by electron probe microanalysis. From these data, we construct a classificatory model for correlating distal tephra to one of five volcanic edifices or eruptive phases within the CAVP. Application of this model to distal deposits of primary tephra-fall and reworked tuffaceous sediments from the archaeological sites of Körkuyu and Kaletepe Deresi 3 indicates Late to possibly Early Pleistocene ages for the artifact assemblages there, and provides a fundamental tephrostratigraphic framework to examine spatial and temporal variation in hominin behavior comparable to that of other regions, such as eastern Africa. 相似文献

El Mirón is a large cave in the Cantabrian Cordillera of northern Spain that presents a long archaeostratigraphic sequence radiocarbon-dated by over 60 assays to between 41,000 and 2000 BP. The sediments, collected from four areas within the cave and sieved-washed with fine wire meshes, contain microvertebrate remains of fish, frogs, lizards, birds and mammals, of which the latter are most abundant. Preliminary taphonomic analysis suggests that the microvertebrates were naturally collected by owls and (less) small carnivores. Small mammal assemblages are useful for palaeoenvironmental reconstruction because they are linked to particular habitats and are sensitive to environmental changes. The small mammals from El Mirón are ideal for this because sample sizes are large, bone preservation is good, and the stratigraphic sequence is long. In this paper we reconstruct the late Quaternary environments in the Cantabrian region of Spain using small-mammal assemblages from El Mirón Cave. On the basis of the ecologic adaptations of this suite of fauna, the majority still extant, we have identified seven habitat types, which are plotted through time. The evolution of the small mammal assemblages at El Mirón reveals seven major climatic shifts that correspond closely to the climatic changes recognized in the Iberian Peninsula during the last 41 kyr. 相似文献
