This article proposes an interpretation of Lope de Vega's El Brasil Restituido (1625) that points to the political, military, and economic crises of Spain in Europe as the underlying themes of the representation of the retaking of the Brazilian colony of Bahía from the Dutch. The Spanish monarchy faced a major challenge to its European supremacy during the first two decades of the seventeenth century. Not only was its military power being frontally contested at different sites of Europe, but its political and economic influence was rapidly deteriorating as well. One of the goals of the Count-Duke of Olivares, the powerful prime minister of Phillip IV, was to regain European leadership by mobilizing the mercantile segments of Spain. The play illustrates the confluence of two ideological systems during the transformation of Spanish feudal society. On the one hand, the dominant ideology of blood purity legitimizes the seigniorial structure of lineage; on the other hand, the representation of a new merchant as a good servant of the king discloses the important role that a mercantile enterprise and ethos had acquired in the formation of a subject to the monarchy.  相似文献

Why do societies implement land policies? A number of arguments have been put forward in the literature, ranging from economic conceptions based on market failure and the problem of negative externalities to a more social conception based on welfare distribution and collaborative planning. However, neither all societies with similar market failures or negative externalities develop and implement land planning nor implemented land planning always results from collaborative planning. The arguments found in the literature seem not to fit the reality and, in most cases, cannot explain why societies create or undertake innovations in land planning. Within the framework of institutional change theory and based on the analysis of the emergence of two land planning devices—a land use law and a land banking law—in Galicia, Northwest Spain, this paper argues that land planning is developed to tackle negative outcomes of former institutional setups. However, the negativity of such outcomes is measured not in terms of economic performance, but in terms of social acceptance. The search for a workable definition of property within the Galician society seems to be the main driver of institutional change in land use planning analysed in this paper.  相似文献

中国热点旅游城市旅游国际化水平定量评价研究   总被引:1,自引:0,他引:1  
闻飞  王娟 《人文地理》2012,27(2):145-150
从国际旅游业发展水平和国际旅游业发展环境两大方面入手,构建了4层39个指标的评价体系,采用层次分析法,定量评价了中国27座热点旅游城市的旅游国际化水平。在此基础上,运用SPSS软件进行聚类分析,将中国热点旅游城市的旅游国际化水平划分为4种类型,最后分析了各城市旅游国际水平的优劣势和提升方向。  相似文献

旅游目的地游客感知价值的层次关系模型   总被引:1,自引:0,他引:1  
张宏梅  洪娟  张文静 《人文地理》2012,27(4):125-130
顾客价值被认为是竞争优势的新来源,目前旅游领域游客感知价值研究多将感知价值的各维度置于同一层次,这样不利于对游客感知价值概念的深刻理解,也不利于旅游业界从操作层面上提升游客感知价值。本研究基于"途径-目的"理论,使用回归分析方法检验了目的地属性层的价值维度与结果层价值维度的关系。结果表明,旅游者对目的地属性层的价值感知显著影响对结果层的价值感知,其中,景观/环境和成本属性是影响中国旅游者体验结果的主导性因素。  相似文献

作为中国城市化水平最高的少数民族,回族社区的地方性在城市化过程中受到严重挑战。论文以"地方依恋"为理论模型,以开封东大寺回族社区为典型案例,对城市回族社区的"地方性"进行深入解读。研究发现,由于围寺而居和强烈的回族认同感,城市回族社区的地方性特征主要受居住时间、文化程度、年龄大小和宗教信仰的深刻影响,地方依恋较深的地方主要在"寺市并存"或距离寺市都近的街道,内部空间上存在不同的宗教知识传承模式。这为丰富社区地理尺度的地方依恋理论和揭示回族社区人地关系机制提供了重要实证依据。  相似文献

We synthesize and discuss available isotopic data on Holocene guanaco samples from southern South America, extending from Tierra del Fuego Island to northern Patagonia and the Pampean region. We evaluate temporal and spatial tendencies on the basis of 91 samples (mainly based on δ13Ccollagen values), presenting implications for paleodietary research in archaeology. We conclude that there are no strong correlations with latitude in the macro-spatial scale, while there is a set of interesting patterns at smaller regional scales. These patterns lead us to evaluate the role of ecologic and topographic variables (e.g. canopy effect, variations in altitude, ecotones) in structuring isotopic variability. Finally, on the basis of the present analysis we suggest a number of hypotheses and perspectives for the use of stable isotopes as geographic tracers of guanaco distribution in the past, and specific implications for the paleodietary study of human samples.  相似文献

Various ethnographic sources have demonstrated the symbolic and ritualistic importance of psychoactive plants in Native American societies. The social milieu of these mind- altering plants appears to be ancient. Archaeological evidence during the Tiwanaku empire expansion along the Atacama Desert of Chile, circa 500–1000 A.D., shows the presence of highly decorated snuffing tablets and tubes as grave goods. The preservation of mummified human bodies in the Azapa Valley, northern Chile, provided an opportunity to test the exact nature of the psychoactive plants used in this region. Using gas chromatography/mass spectrometry (GC–MS), here we show that ancient Andean populations from northern Chile consumed Banisteriopsis, a vine that contains harmine. This is the first direct archaeological evidence of hallucinogenic and medicinal ethnographic practices. Interestingly enough, this rainforest plant does not grow along the Atacama coast, thus our findings suggest extensive plant trade networks in antiquity as far as the Amazon.  相似文献

截至2013年5月,世界酒店业300强中在中国形成网络化经营的20家国际酒店集团已在我国221个城市有布局。不同于以泰勒为代表的基于跨国生产性服务企业布局的城市连接度研究,本文以消费性服务企业中的国际酒店业在华布局为研究切入点,通过城市网络连接度测度发现:第一,我国酒店业城市网络已形成以上海、北京、杭州、西安为中心的层级体系,上海已具备成为国际酒店业首位城市和世界级旅居城市的条件;第二,在环渤海、长三角和珠三角三大经济区域中,基于国际酒店集团服务价值判定的区内和区际城市连接度水平存在较大差异,其中长三角地区连接度总和与均值最高;第三,在酒店业的全球生产网络中,中国城市的酒店业布局具有品牌层次的低端锁定特征,中心性和总部经济效应有待提高。  相似文献

In this paper we analyze the effect of infrastructure on the cost and productivity performance of the private productive sector of Spanish regions over the period 1980–1993. We use a dual approach based on cost functions that allows us to recover the usual parameters estimated with production functions. In addition, we obtain rates of return and cost elasticities of production factors at the regional level. Our framework explicitly considers that some factors are quasi-fixed and their volume can differ from their optimal endowment levels. Our results indicate that the public sector has contributed significantly to enhance productivity and reduce costs in the private sector of almost every Spanish region. Nevertheless, there is still scope for the government to continue its investment efforts, given that there remains an appreciable gap between observed and optimal public capital, and we find that in the long run, public capital promotes private investment.  相似文献

Abstract We formulate a microeconomic model of residential location choice behavior as an aggregate of the individual behaviors of household members, subject to individual time constraints and a common income budget. A simplified version of the model is estimated from stated preference rank‐order data, yielding a function that may be interpretated as a conditional indirect utility function. We consider Box‐Tukey transformations, segmentation by income class, and a consistent treatment of data at different rank depths using the simultaneous mixed‐estimation method. Measures of the household's willingness‐to‐pay (through rents) for reducing travel times to work and study in the short run, are interpreted as subjective values of time and compared with such values derived from mode choice models. Our results are plausible, and consistent with recent findings showing that the short‐run benefits of transport projects derived by transport models are larger than benefits measured at the land use system.  相似文献
