Recherches sur la nuit vénitienne à la fin du moyen âge

An important conclusion emerges from an examination of Venetian public acts of the late middle ages: noclurnal supervision became, from the thirteenth century onward, a necessary and permanent pre-occupation of government. This calls for a study of the definition of night-time and of the administrative framework, which reveals an evolution from traditional structures to magistratures specifically charged with maintaining public order. A question arises: fear of the night is ancient and profound; why did the desire to control and master it emerge so late? It seems that the Republic feared real violence less than political violence in the widest sense of the term. Because the night represented a kind of freedom, it had to be brought under control. This found its place within the more general plan of regulating behaviour, a logical result of the constitution of the Venetian state.     

Has it become warmer in Alberta? Mapping temperature changes for the period 1950–2010 across Alberta,Canada

When a Canada‐wide daily climate time series, covering the period 1950–2010, became available, an opportunity arose to analyze the time series for trends of a variety of temperature indices. The 6,833 climate grid cells covering Alberta, each with an area of 10 km by 10 km, allowed the detailed mapping of 30 temperature indices across the province. From each time series, an annual series was computed, which then enabled trend analyses using the non‐parametric Mann‐Kendall and Sen Slope tests. New maps could be created at an unprecedented spatial resolution, and an associated website was developed to access all trends and changes between 1950 and 2010 for all grid cells at albertaclimaterecords.com . The confidence levels of some temperature trends exceed 99%, while others are below 80%. In Alberta's south, annual average temperatures have increased by 1°C to 2°C since the 1950s, but in Alberta's north the increase is 2°C to 4°C. The growing season has lengthened by between one and five weeks since the 1950s, while the number of frost days has declined. The most significant trends observed were increases in mean annual and winter temperatures, and declines in the number of days below ?20°C and heating degree days.     

Northern Laboratories of Nature and the Quest for Scientific Honour in Early Modern Sweden

Abstract

This article studies the role of climate and geography in the scientific networks which were taking form in Europe in the early modern period. It seeks to contribute to an analysis of the meanings attributed to the North as a scientific environment or an object of study and, in particular, show the wider contextual motivations behind the research of the northern lights as well as phenomena related to physical cold. The analysis will concentrate on the learned discussions taking place between scholars in the Kingdom of Sweden and the Académie des Sciences in Paris. The great scholarly interest in the aurora borealis starting in the early eighteenth century emerged rapidly after the sudden appearance of this striking and enigmatic phenomenon across a large part of Europe during the first decades of the eighteenth century. In a similar manner, cold winters experienced all over Europe during the late seventeenth century had inspired the first scientific societies in Europe to carry out experiments that under ordinary circumstances could not have been pursued. These events underlined the dependency of early empiricists on nature's help when extending the scope of their scientific inquiries. The awareness of the constraints of empirical study, combined with a new ideological view of scientific societies as seats of a collective scientific effort, prompted a new kind of specialization in science. The idea was introduced that each scholar or country should take care of producing experiments and observations that were best attainable in their particular environment. The need became most obvious in research topics such as the cold which – unlike heat – could not be produced artificially. As a demand for observations that were specific to northern tracts emerged in Europe, northern scholars discovered in their expertise on the northern issues a niche to negotiate a new prestige in the European scientific networks. Traditional views had maintained that only the warm, southern climates offered a natural environment for civilisation and arts to flourish. New empirical sciences practised by the scientific societies seemed to provide a convenient break with this assumption.     

America's Protégé in the East? The Emergence of Poland as a Regional Leader

Following the events of September 11 Poland has emerged as one of the key allies of the United States—arguably its protégé in east-central Europe. The close affinity of interests on security matters between the two states became even more apparent in Afghanistan and then more recently over Iraq, where Warsaw has proved to be a strong and highly vocal supporter of Washington's stance. The overall context to this is provided by the growing divergences between the US and Europe, but especially within Europe, towards the situation in Iraq, which has prompted endless commentary based around notions of 'old Europe' and 'new Europe' and 'American power and European weakness'. This article will reflect upon these debates and explore Poland's position within them by addressing the notion that Poland is becoming a regional leader. The 'instinctive' Atlanticism within Poland's strategic culture drives Warsaw's security policies and is evident across a range of examples. Focusing on the missile defence initiative and ESDP as key issues where there has been a clear set of interests between Poland and the US, it will be demonstrated that Warsaw has always opted for Atlantic as opposed to European solutions and institutions to meet its security needs. A question remains, however, as to whether Poland can continue to be America's protégé and whether Warsaw has the political will and capacity to assume the role required of it by the US, or a regional provider of security in the longer term. This article proposes that to assure this, Poland's eastern policies require not only a more focused and consistent line but also that its security thinking needs to be 'modernized' and should be led by a 'security' rather than a 'traditional defence' rationale reminiscent of the pre-1989 era.     

FELLOW CITIZENS AND IMPERIAL SUBJECTS: CONQUEST AND SOVEREIGNTY IN EUROPE'S OVERSEAS EMPIRES

This article traces the association between the European overseas empires and the concept of sovereignty, arguing that, ever since the days of Cicero—if not earlier—Europeans had clung to the idea that there was a close association between a people and the territory it happened to occupy. This made it necessary to think of an “empire” as a unity—an “immense body,” to use Tacitus's phrase—that would embrace all its subjects under a single sovereign. By the end of the eighteenth century it had become possible, in this way, to speak of “empires of liberty” that would operate for the ultimate benefit of all their “citizens,” freeing them from previous tyrannical rulers and bringing them under the protection of more benign regimes. In such empires sovereignty could only ever be, as it had become in Europe, undivided. The collapse of Europe's “first” empires in the Americas, however, was followed rapidly by Napoleon's attempt to create a new kind of Empire in Europe. The ultimate, and costly, failure of this project led many, Benjamin Constant among them, to believe that the age of empires was now over and had been replaced by the age of commerce. But what in fact succeeded Napoleon was the modern European state system, which attempted not to replace empire by trade, as Constant had hoped, but to create a new kind of empire, one that sought to minimize domination and settlement, and to make a sharp distinction between imperial ruler and imperial subject. In this kind of empire, sovereignty could only be “divided.” Various kinds of divided rule were thus devised in the nineteenth century. Far, however, from being an improvement on the past, this ultimately resulted in—or at least contributed greatly to—the emergence of the largely fictional and inevitably unstable societies that after the final collapse of the European empires became the new states of the “developing world.”     

Agricultural Transformation and the Politics of Hydrology in Northern Thailand

Tensions over water resources in upland areas of northern Thailand are often attributed to reductions in water supply caused by forest clearing. This article argues that the hydrological evidence for such reductions in supply is very weak and that, rather, the key hydrological issue in upland catchments is a significant increase in water demand, especially during the dry season. The arguments are illustrated with a detailed examination of the Mae Uam catchment, located in Chiang Mai province, where the development of dry–season soybean cultivation appears to have tested the hydrological limit of the catchment, and even exceeded this limit in drier years. The author argues that a shift in focus from water supply to water demand has fundamentally important political implications. As long as the focus of public debate is on water supply, the regulatory focus will be on those resident in the forested upland areas that are seen as being crucial in securing downstream flows. But if the water management focus is shifted to water demand, then regulatory attention must shift to the diverse sources of demand that exist throughout the hydrological system.     

The ionosphere: morphology,development and coupling

The morphology of the MAP/WINE winter is examined, principally from ground-based and satellite observations. Winter anomaly is evident, occurring in bursts with a west to east shift in time. Auroral activity, particularly with reference to the times of major rocket salvoes, is generally low, with Andøya to the south of the auroral boundary in most cases. Minor stratospheric warmings, of which 4 occurred, are found to correlate with minima in radio wave absorption. Salvo R1 was launched during one of the minor warmings.Using data from a broad sector of Europe, coupling between the lower thermosphere and mesosphere is seen over large areas. Westerly winds are associated with high absorption (winter anomaly) and reversal to easterly winds with stratospheric warmings and low absorption. It is found possible to select cases, from amongst the MT series of rocket launchings, corresponding to quiet conditions, stratospheric warming, winter anomaly and particle precipitation in the general absence of other effects. Examining D- and lower E-region ionisation profiles for these caes it is found that, compared with a quiet night, the stratwarm night shows the lower E-region to have reduced ionisation. The ionisation ledge is of similar shape in all cases, but occurs over different height ranges. The observed effects all point to transport being a major factor and the need to measure vertical transport over the range of geophysical conditions examined is highlighted.     

良渚先民的体质特征与经济、环境适应关系研究——以上海松江广富林遗址出土人骨的体质人类学研究为例

本文在对上海松江广富林遗址良渚文化墓葬出土的人骨古食谱和骨骼病理分析基础上,探讨了良渚先民的体质特征与经济、环境的适应关系。稻米在良渚文化居民饮食结构中的比重逐渐提升,到良渚文化中晚期,已经成为重要的食物。良渚社会通过改良水稻品种、精细加工生产工具和大量开凿水井等方法提高水稻产量,粮食的增加使良渚社会人口数量膨胀,聚落数量猛增,良渚社会进入繁荣。一方面是繁重的农业生产和费时费力的渔业捕捞劳动,另一方面是建立在神权之上的社会制度,都使良渚文化居民的劳动强度大大增加,居民寿命普遍较短,大多在成年甚至壮年期死亡。高强度的劳动使骨性关节炎的发病率很高。     

土遗址裂隙注浆材料PS-(C+F)与SH-(C+F)性能对比研究

西北干旱、半干旱地区保存有大量的土遗址,裂隙、淘蚀、洞穴、冲沟、坍塌等一系列病害对遗址的破坏作用明显。就裂隙注浆材料而言,本研究基于PS-(C+F)的成功应用,为使注浆材料多元化,对比研究SH-(C+F)浆液作为注浆材料的适用性。通过室内对两种材料的力学性能、水理性质、抗冻性、抗老化性的比较以及现场对裂隙加固效果的检测,最终分析数据得出结论,SH-(C+F)与PS-(C+F)的力学性能相当,但SH-(C+F)的抗渗性、抗崩解性、抗冻性、抗老化性等略好一些。因此,SH-(C+F)浆液适宜作为注浆材料应用于土遗址裂隙加固中。试验结果对西北地区土遗址裂隙加固材料的多元化有重要的参考意义和指导作用。     

Demography and the extinction of European Neanderthals

Causes previously suggested for the sudden extinction of Neanderthals (Homo neanderthalensis) in Europe, starting around 35,000 years ago, comprise food shortage, climatic effects and violence from Modern Humans. The aim here is to formulate a demographic model with reconstructed fertility and death rates, capable of modelling the population development under conditions of changing climate and prey availability, from the early appearance of Neanderthals in Europe about 260,000 years ago to their demise. Parameter variation studies are made for the parameters considered to have the highest uncertainty. Finally, the option of regional migration between northern, middle and southern Europe is added, in order to capture population movements away from a region in response to deteriorating or improving climate. This model accounts for population developments, including the re-population of the Middle and Northern regions of Europe during and after the warm Eem period. However, parameter choices that give plausible results during the initial 210,000 years also predict that the Neanderthals should have survived the latter part of the Weichselian ice age, despite competing for food with Modern Human newcomers during the last part of the period. The conclusion is that other reasons for extinction than climate or starvation must be sought.     

Histories of analytic political philosophy

This paper sets out an agenda for the study of the history of analytic and post-analytic political philosophy. It builds on a growing literature on the history of analytic philosophy to make three main suggestions. First, analytic philosophy arose as part of a wider shift from the developmental historicism of the nineteenth century to more modernist modes of knowledge. Second, analytic philosophy included a wide range of approaches to moral and political issues, many of which reflected distinctive concepts of analysis, logic, and science. Third, analytic philosophy only became widespread when the work of Quine and Wittgenstein moved it in a more post-analytic direction. Crucially, the move toward post-analytic philosophy inspired people to rediscover and reinvent other traditions, including liberal humanism, democratic republicanism, virtue ethics, and historicism. The resulting history provides a fluid and diverse understanding of arguably the most powerful philosophical movement of the twentieth century.

Between National Socialism and expert internationalism: Karl Strölin and transnationalism in urban planning, 1938–45

This essay examines the transnational activities of National Socialist experts, focusing on the endeavours of the burgomaster of Stuttgart, Karl Strölin. In 1938, Strölin became president of the International Federation for Housing and Town Planning (IFHTP), one of the most distinguished international expert institutions for European and North American urban planning. The article discusses his belief that promoting an international convention on the protection of urban populations would contribute to German diplomacy in the initial period of the Second World War. Then it investigates the IFHTP president’s efforts to transform his institution into an outlet for National Socialist ideas against the background of the German advance through Europe. A final section deals with Strölin’s attempts to transform the IFHTP into a forum for evaluating urban reconstruction policies in the last year of the war. This biographical study shows how it was possible to juggle the logics and expectations of seemingly contradictory spatial and political realms during and after World War II. National socialist politics and ideology exacerbated the tensions between local, national and international affiliations, but at the same time never fully permeated the mechanisms of expert internationalism. By revealing how Strölin navigated between local ambitions, the demands of domestic foreign policy and the ethics of expert internationalism in three markedly different projects, this essay contributes to a growing body of scholarship on the cross-border activities of National Socialist professionals in (occupied) Europe.     

Businesses, Green Groups and The Media: The Role of Non-Governmental Organizations in the Climate Change Debate

The lion's share of media and governmental commentary on the recent Sixth Conference of the Parties (COP-6) to the UN Framework Convention on Climate Change has focused on rifts between the EU and the 'Umbrella Group' of countries, including the United States, Canada and Japan, and has led many observers to speculate that intergovernmental negotiations on climate change may have irretrievably broken down. Limiting the focus solely to political difficulties with specific issues, however, emphasizes only part of the story and takes no account of the complex context in which the international negotiations are embedded. This approach does not give sufficient credit to the growing momentum gathering outside the negotiating halls. This article examines recent and rapid changes in attitude and awareness among non-governmental groups-including business and industry, environmental groups and the media-on the issue of global climate change, and the impact these changes have had on the negotiating process and the overall climate change debate. Together these groups provide encouraging signs of a shift in public opinion and ample proof that the failure of the talks in The Hague does not signal the end of the road.     

Deglaciation and Human Colonization of Northern Europe

Few places worldwide experienced Late Glacial ecological shifts as drastic as those seen in the areas covered by, or adjacent to, the massive ice sheets that blanketed much of the northern hemisphere. Among the most heavily glaciated regions, northern Europe underwent substantial ecological shifts during and after the Last Glacial Maximum. The climatically unstable Pleistocene–Holocene transition repeatedly transformed far-northern Europe, placing it among the last regions to be colonized by Paleolithic societies. As such, it shares paleoenvironmental and archaeological analogues with other once glaciated areas where human populations, entrenched in periglacial environments prior to glacier retreat, spread into newly deglaciated territories. Perhaps most significant for northern Europeans were post-glacial effects of the Younger Dryas and Preboreal periods, as shifts in climate, plant, and animal communities elicited several adaptive responses including innovation, exploration, and the eventual settlement of once glaciated landscapes. This paper is a detailed review of existing archaeological and paleoecological evidence pertaining to the Late Upper Paleolithic of northern Europe, and offers theoretical observations on human colonization models and ecological responses to large-scale stadial and interstadial events.     

Beyond Annexationism: The Central Powers’ Ostpolitik as Structural Transformation, 1917–18

This article explores the eastern policy of Germany and Austria-Hungary during the latter half of the First World War (1917–18). It attempts to go beyond the traditional annexationist–non-annexationist dichotomy prevalent in the literature and approach the issue from the perspective of structural transformation of the international system. It argues that the Central Powers endeavoured to accommodate imperial collapse in Eastern Europe and prevent its further spread by replacing the obsolete system of imperial dynasticism with a new arrangement based on autonomous and semi-autonomous states. German and Austrian leaders often disagreed on implementation and formed temporary understandings across the civilian–military divide. This policy ultimately proved counterproductive, as it failed to contain the westward spread of national and social revolution. Austro-German support for nominally independent states in Eastern Europe, national in form but Central European in cultural and political outlook, inadvertently contributed to further imperial collapse, as the increasingly restless nationalities of Austria-Hungary began to challenge the legitimacy of imperial dynasticism in Central Europe. The Central Powers’ Ostpolitik in 1917–18 became a transformative historical event due to the fact that it facilitated the structural transformation of international relations in Central and Eastern Europe from imperial dynasticism to a system of nation-states.

历史时期的"黄河清"现象初探

古人对黄河清有“祥瑞之兆”和“不祥之征”两种观点。黄河澄清是一种自然现象,却又不可能出现在正常条件下,它有其内在的规律。只有当流域内大范围出现异常情况,如持续干旱少雨、冬季过于寒冷、地震等时,才会导致黄河河水变异,出现黄河澄清的现象。黄河清是干旱和黄河断流的前兆。同时,黄河清还与社会政治、化和生活交织在一起,成为奇异的化与社会现象。     

Ensuring Benevolent Neutrality: The British Government's Appeasement of General Franco during the Spanish Civil War, 1936–1939

This article examines the development of British non-intervention in the Spanish Civil War (1936–39). Previous studies have focused heavily on pro-rebel or anti-Republican sentiments among British officials in London and abroad, and often apply the term ‘malevolent neutrality’ to the motives behind the policy. However, utilising records from the National Archives as well as private papers, this article evaluates British non-intervention within the context of appeasement and demonstrates a clear link between the two policies. By examining British neutrality through the lens of appeasement, this study will enhance our understanding of British diplomacy in the 1930s and the links between non-intervention in Spain and the growing threat of fascism in Europe. It argues that the British Government adopted and maintained a policy of strict neutrality in order to avoid an escalation of the conflict and to place itself in a better position from which it could establish a good relationship with whichever side emerged victorious. As it became increasingly clear that the rebels were going to overthrow the Republic, the British Government began to tacitly appease General Franco in an attempt to avoid a hostile Spain in the build up to the Second World War.
