明清时期潮州粮食供给地区及路线考 总被引：2，自引：0，他引：2
明清时期, 潮州地区由于商品经济的发展, 粮食日益不能自给, 不得不到本地区之外购买粮食。随着粮食需求的不断增大, 江西赣州, 广东雷州、琼州、高州, 福建厦门、台湾, 东南亚暹罗、越南等国先后成为潮州粮食的供给地。粮食供给地的变化, 引起贸易路线的变迁。潮州粮食贸易亦与潮州华侨出国有很大关系, 潮州的粮食贸易形成自己独特的原因和规律。 相似文献

Thermal springs are commonly thought to be an indicator of geothermal resource potential. However, there have been few analyses of the relationship between thermal springs and the underlying thermal regime. An examination of temperature and discharge rates for a large database of thermal springs in North America demonstrates that there is not a simple relationship between these measurements made at the surface and subsurface heat flow. Hydrogeological factors appear to exert strong controls on the temperature and discharge at these springs and should be carefully considered in geothermal resource assessments. 相似文献

我国农产品物流模式演进分析 总被引：2，自引：0，他引：2
从农产品流通体制由统购统销向市场化改革演变历程的考察看,中国农产品物流模式的历史性演变经过了计划经济时期农产品物流发展的起步阶段、转型期农产品物流市场化初步发展阶段以及宏观调控下以市场为主的自由流通等阶段,其发展脉络与我国经济体制改革的实践和各个时期经济发展的某些特殊条件是一致的,模式的每一次演变也都带着中国经济改革的烙印。 相似文献

This article examines the influence of the Neapolitan philosopher and economist Antonio Genovesi on academic debate during the Enlightenment in Spain in the latter decades of the eighteenth century. In particular, it focuses on the reaction aroused by his famous Lezioni di commercio (1765–7). The success of Genovesi's work in Spain is evident in the many translations of the Lezioni carried out over the years by many analysts, from pioneering historians such as Venturi to more contemporary commentators. In this article we shall endeavour, first, to study all the different Spanish versions of Genovesi's book and, second, to demonstrate that Genovesian influence in Spain was heterogeneous, which is why the Lezioni provides a very illustrative example of the struggle between the various reformist and anti-reformist strategies circulating in late eighteenth-century Spain. At the same time, it provides a good standpoint from which to observe the powerful flow of ideas from Naples to Spain during the Enlightenment. 相似文献

AbstractChristopher Wren’s figure of the brain ‘viewed from below’ in Thomas Willis’s Cerebri anatome (1664) set a precedent, not only for subsequent images of the brain, but for scientific illustration. The image is the visual proof of a Baconian experiment conducted by the Oxford dissection team, in which dye was pumped into the carotid arteries of animal and human specimens in order to imitate the natural flow of blood, thereby applying William Harvey’s theory of circulation to the brain. Usually described as engravings, Wren’s images are in fact etchings (produced by the acid process), significant because etching for book illustration was then in its infancy in England. In addition to considering Wren as an experimental etcher, this article frames our understanding of Wren’s contributions to Willis’s project in terms of his virtuosic talents as amateur draughtsman, natural historian, anatomist, and his use of optical and draughting instruments. 相似文献

Downscaling is a term that has been used to describe the range of methods that are used to infer regional‐scale or local‐scale climate information from coarsely resolved climate models. The use of statistical methods for this purpose is rooted in both operational weather forecasting and synoptic climatology and has become a widely applied method for development of regional climate change scenarios. This article provides an overview of statistical downscaling with a focus on assumptions, common predictors and predictands, and methodological approaches ranging from interpolation and scaling to regression‐based methods, weather pattern‐based techniques, and stochastic weather generators. Suggestions are made for improved assessment of the fundamental downscaling assumptions as well as reduction of uncertainty associated with application of downscaled climate information across models and greenhouse gas emission scenarios. 相似文献

Abstract: The aim of this article is to improve our understanding of finance in home building by introducing an actor perspective in structure‐oriented theories of capital circulation. David Harvey's three‐circuit theory, with fixity‐motion processes and (de‐/re)‐territorialisation, is taken as the starting point. The analysis is based on a case study of Norwegian home‐building finance, outlining the emerging structure of housing and finance under the Norwegian version of neoliberalism; comprising deregulation and re‐regulation phases. The article delineates today's home‐building finance, and identifies large banks, small banks, large investment funds and small investment funds as structural actors operating within actual fixity and motion processes, causing a distinct territorialisation of urban landscapes, as exemplified by gentrification. 相似文献

Over the past few years a considerable body of research has illuminated the changing geographies of service provision in rural Australia. Mostly, this work has emphasised the quantitative aspects of restructuring, by way of documenting numerical reductions in service delivery points and their implications for local employment and service access. In this paper, an examination of recent restructuring within the dealership system for high‐horsepower tractors underlines that these quantitative changes also intersect with qualitative shifts to the character of service delivery. Interviews with 31 participants in the tractor dealership system of Central‐West New South Wales reveal the recent evolution of a producer‐driven supply chain in which two dominant, multinational, tractor‐machinery companies have sought to exercise tighter control over customer relations through the restructuring of franchise agreements with dealers. There has been a resultant demise of the independent dealership, and its replacement by a system of standardised, company‐affiliated outlets operated by franchise holders. Hence, the spatial restructuring of this industry represents the surface manifestations of corporate strategies in which large economic entities are re‐organising their interests in light of globalised theatres of competition and profit. In this sense, the tractor‐dealership system is emblematic of changes to power and control in rural service provision as the franchise models propagated by large corporate interests increasingly subsume the small‐business sector activities of Australia's rural towns. 相似文献

Christopher Hill's National History and the World of Nations reminds us of the conjunctural moment of an emerging world market in the latter half of the nineteenth century and the promise it offered for vitalizing a “world history” yet to be written. More importantly, it supplies the silhouette of a radically different interpretive approach, formed by the force of a centrifugal perspective that—through its concentration on how France, the United States, and Japan were simultaneously motivated to construct representations of self‐identity in national narratives—converged to disclose the possibility of a wider world no longer held hostage to the geopolitical category of the “West.” Hill's account shows that the impulse behind the formation of national history employed different strategies to imagine a singular linear historical narrative of national identity that aimed both to remove the spectacle of coexisting, different, multiple temporalities and to weld large and regionally disparate populations into a single people who, in a new time, would be instructed to recognize themselves in the nation's story. In Hill's reckoning, national history in France, the United States, and Japan appears simply as another name for historical necessity that sought, through processes of naturalization and nationalization, to overcome the unstable and uneven relationship between state and capital but that failed to conceal the deeper reality of determinations demanded by the relations of capital at the local and international levels. 相似文献
