The Portuguese revolution of October 1910 instituted a civilian revolutionary and ‘progressive’ Republic within the background of a conservative and monarchist Europe, whose core was located in the countries of the Triple Alliance. Since its very beginning, the regime fell short of any foundational consensus and was caught by a wave of conspiracies, upheavals, social protests and civil war menaces. This article sheds light on the shortcuts adopted to overcome the political instability examining political procedures like legislative coups, wishful thinking and ad hoc planning. The final part broadens the debate through the assessment of the time frames and the types of effects that policy failure is able to bring about.  相似文献

国际旅游与国际贸易是相互联系的,旅游引发贸易、贸易推动旅游。本文在前期研究工作的基础上,提出了一个旅游与贸易互动的三阶段模型,即旅游引发贸易、贸易推动旅游和偏好-容量限制3个阶段。以日韩东盟8国为例,选用1986年-2009年统计数据,分析了8国入境我国旅游与进出口贸易的关系,构建了入境客流量与进口贸易、出口贸易和进出口贸易3组24个推拉方程。在此基础上,以1992年和2002年为分界点,分析了各阶段入境客流量与进口贸易、出口贸易增长率的变化及弧弹性;依据每万人次入境旅游引发的进出口贸易强度,将日韩东盟8国划分为四种类型,分析了近10年来旅游引起进出口贸易强度的变化,为通过旅游拉动贸易或通过贸易推动入境旅游发展提供了科学依据。  相似文献

关于中国稻作起源的研究至少可以追溯到1930年代(丁颖1933)。1970年代河姆渡遗址的发现更把这一研究推向新的高潮。最近.国内外学术界就稻作在长江流域起源的地点和时间,以及一些重要考古学遗存是否进入“发达的稻作社会”等问题展开了颇为热烈的讨论(i.e.Fuller and Qin2008;Fullereta1.2007;Liueta1.2007)。  相似文献

长安大唐西市不仅是1000多年前我国社会发展、经济繁荣、文化发达的港口,是丝绸之路的起点和国际贸易中心,而且也是古代历史上第一个具有特区性质的城区。当时在西市及周边地区,居住着大量来自中亚、西亚的外国人.中央政府对他们采取了开明、开放和包容的政策,不仪给予礼遇和保护,而且通过设立蕯宝府(管理祆教事务)和“藩坊”(管理伊斯兰教事务),让他们自己管理自己的事务,使大唐西市具有典型的“文化特区”性质。在经济方面.中央政府采取了一系列的保护、鼓励和优惠政策来促进丝绸之路的商贸往来和大唐西市的繁荣与发展。加之在当时的西市中,有具有典当性质的寄附铺.具有早期银行性质的柜坊,具有早期中介和物流性质的波斯邸和常平仑等。因此.该区域是我国占代历史上第一个具有特区性质的城区。  相似文献

古代都城的选址与政治经济等诸多要素相关,其中与环境的关系尤为密切,西安作为历代兴盛王朝的都城,在中国都城史上占据着重要地位,本文以汉、唐两代西安地区自然环境和气候变迁为切入点,讨论都城选址与环境之间的关系。  相似文献

We see what we are prepared to see. Scientific research aims at breaking down this situation, analysing its subjects/objects of study from different points of view. Although multiple meanings can be derived from every question and a myriad of positions can be adopted, some are bound to be silenced by traditional criteria of authenticity. Archaeology is not an exception to this: the prevailing agenda severely impacts on our perception of what archaeological practice consists. In turn, its ethos is recreated as part of our own identity processes through our productions, whether by passively accepting monolithic standards or by dynamically proposing alternative positions in response. The study of the prehistoric and colonial periods in America can be a good test bed for surveying the influence of academic background upon the analysis of human history. Here we review two Spanish journals of American studies to discuss the different orientations of the authors according to their provenance. Plotted against the country represented by the authors, we consider his/her research as regards the object of study (ie. artefacts/written sources), its origin, chronology and, finally, the aim of the paper. We found interesting orientations in relation to focus on particular subjects, most probably conditioned by the ontology of the researchers. Although the selection is quite taxative, it may usefully complement studies carried out in the Americas.  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

The comparative study of sedimentary fabrics in relation to archaeological fabrics in various levels of the sites of Cova Gran de Santa Linya (Middle and Early Upper Palaeolithic) and the Roca dels Bous (Middle Palaeolithic) has made it possible to analyse the formation dynamics of the deposits and determine the extent of disturbance of the archaeological levels by natural processes. To achieve this, diagrams and two- and three-dimensional indices were calculated from the azimuth and dip angle of natural clasts and artefacts. The results indicate that the sedimentary levels were formed mainly by planar fabric shape gravitational processes (low depositional angles), which differ notably from the archaeological fabrics they contain, characterised by a greater degree of isotropy. This difference in the fabrics would reflect human activity and indicates that the archaeological levels both in Cova Gran and Roca dels Bous have not been subject to significant natural modifications, and are preserved in situ.  相似文献
