Effects of momentum deposition due to solar diurnal and semi-diurnal tidal waves on the zonal mean circulation in the mesosphere and lower thermosphere for a solstice condition are discussed. In the present model, the system of zonally averaged equations and the system of perturbation equations are integrated simultaneously, so that the propagation of tidal waves is affected not only by the basic mean fields but also by the induced zonal mean fields due to the momentum deposition. Results for two different vertical eddy diffusion profiles are presented. It is shown that the solar tides make a significant contribution to the generation of the mean zonal winds in the upper mesosphere and the lower thermosphere. Below 120 km the main contribution is due to propagating diurnal tides, while above 120 km it is due to semidiurnal tides.  相似文献

Tracing the international career of the 1776 Virginia Declaration of Rights to Sweden via France, this article is a study in the translation of politics and the politics of translation. Specifically, it shows how the Swedish translator, physician and publisher Lorents Münter Philipson (1765–1851) reached for it in 1792 to add to domestic arguments against hereditary office, the purpose of which, the article argues, was to revive and legitimise a more indigenous but by now slumbering rights revolution. The article first outlines the reception of America in Sweden and the ways in which Sweden figured in American debates. It then provides a detailed analysis of the trial that ensued as a response to the Swedish translation of the Virginia Declaration. Having reconstructed the process of transmission and the trial, during which the translator was charged with attacking Sweden's monarchical constitution by means of ‘wrongly’ translating the term ‘magistrate’, the article places the translation of the declaration in political context. The contextual analysis shows that translating the declaration at this particular point in time makes most sense against the background of the events unfolding in revolutionary France, which the translator hoped would influence political developments in Sweden and which the authorities sought to suppress.  相似文献

The aim of this article is to evaluate the resilience of territories through a study of the morphology of local firms' networks: in this case, in the Montpellier urban area. Two types of data collection were used for the analysis: a statistical survey of a sample of firms and a list of shared patents pending. The first step of the approach enabled us to analyse the motives that led firms to develop innovative partnership. In the second step, we modelled the networks, using graph theory, over different periods of time. Ultimately, the analysis revealed pivotal firms within the network. These firms played an important role in the resilience and spatial organization of the territory. We found that the geographical concentration or dispersal of the firms thus continued under certain economic conditions.  相似文献

During the last glacial period, a large part of the Aquitaine basin (southwest France) was a periglacial desert comprising coversands with low-relief dune fields surrounded by loess accumulations. OSL and radiocarbon dates show that the phase of maximum sand deposition coincides with Marine Isotope Stage (MIS) 2. Peats and gleyic palaeosoils intercalated within the sands at some sites indicate that vegetation cover was able to develop locally during short events, possibly D–O interstadials, due to raised groundwater levels in interdunal depressions. Few Palaeolithic sites have been discovered in the coversand area in contrast to the peripheral loess region. Systematic survey along a future highway corridor demonstrates that this paucity of sites is not the result of insufficient survey nor deep site burial, but rather reflects an archaeological reality. This strongly suggests that the sand area was not attractive for hunter–gatherer populations due to its reduced levels of water resources, and available vegetation and animal biomass. The distribution of cultural markers such as art items and projectile points also shows that the coversand area probably acted as a barrier separating two different cultural sub-areas, one in the Pyrenees and Cantabria, the other in the Périgord. As a consequence, the commonly accepted view that southwest France, as a whole, served as a refugia during the cold and arid phases of the Pleistocene should be replaced by a more complex one that reflects the fact that a large part of the territory was almost unoccupied and that human populations were concentrated along alluvial valleys.  相似文献

French historians have recently begun to pursue the historyof left-wing politics in a manner which suggests that the Marxistframe of reference has begun to disappear, even in this fieldof history. The eminent historian and public intellectual PierreRosanvallon is leading the way in the field of political andintellectual history, through his sustained examination of theState and the ongoing debate about French democracy. The connectionbetween history and current political discourse is important,and it is significant that historians are attempting to revisecommon perceptions of the evolution of French political institutions.Wide areas of new research have been opened out and this articlehopes to offer some reflections on how these new approachesto French political history may be used in future research.  相似文献

We report here the results of strontium, oxygen and carbon isotope analysis of teeth from domestic animals at two Neolithic settlement sites in Falbygden, Sweden. The main result is the high mobility of domestic animals, particularly of cattle but also of sheep. More than half of the analysed cattle teeth show strontium isotope signals indicating that they were raised in an area of Precambrian rock, outside the sedimentary Cambro-Silurian rocks found in Falbygden. This is in marked contrast to pigs, which were mostly local to Falbygden. The mobility of cattle is much higher than that of humans, for which the frequency of immigrants is about 25%.  相似文献

Grotte XVI (Dordogne, France) contains a rich archaeological sequence that begins during the Mousterian and continues through the Magdalenian and includes Châtelperronian and early Aurignacian assemblages. Analyses of the ungulates from this site show no significant change in skeletal part representation, butchering intensity (as measured by cut mark numbers and placement), degree of bone fragmentation, and intensity of carnivore damage across the Middle-to-Upper Paleolithic transition. Relative taxonomic abundances of ungulates change significantly from the Mousterian to the early Aurignacian, but these changes are consistent with climatic forcing and continue throughout the sequence. Only the Magdalenian ungulate assemblage is clearly distinct from all others when examined in terms of these variables, perhaps because of altered predator/prey ratios on the local landscape. Cave bear relative abundances decline precipitously across the Middle-to-Upper Paleolithic transition; this decline may reflect increased human residence times and/or group sizes during this interval, just as Kurtén observed many years ago.  相似文献

Abstract

Over the past three centuries Italy has been the focus of numerous studies by French historians, who have taken advantage of the great wealth of sources available there. While no new synthesis has yet been achieved, we can identify certain main lines of development in French historiography. In the late 1970s and into the 1980s international relations and, especially, the relations between France and Italy were given the greatest attention, before a new focus on forms of sociability and political pedagogy began to be more common. However, the shifting of focus of historical studies to the centres of political decision making often coincided with less attention being paid to social stratification. Beyond these major themes, some researchers have reconstructed ‘global’ historical models, which have been characteristic of the renewal of post‐war French historiography.  相似文献

Thermoluminescence dating of heated flint artefacts from the Middle Palaeolithic sequence of Chez-Pinaud Jonzac (France) places an assemblage of Quina type Mousterian into MIS 4, while the overlying assemblage of Denticulate Mousterian which is followed by two layers with Mousterian of Acheulean Tradition are all assigned to MIS 3. TL dating is used to verify the mixed nature of deposits from which diagnostic Middle as well as Upper Palaeolithic tools were recovered. The TL ages are significantly different for samples from this layer and broadly agree with the archaeological attributions. While the study is generally limited by the low number of heated samples available, a correlation with a generalized chronostratigraphic sequence is possible by including proxy data from the faunal remains associated with the lithic assemblages in question. The Quina Mousterian in southwestern France, therefore, can be placed by chronometric dating methods in MIS 4 to MIS 3.  相似文献

本文主要分为三个部分:第一部分,通过当前关于世俗化理论争论的梳理,说明法国世俗化问题的理论意义;第二部分,说明法国世俗化的特殊表现,强调了法国世俗化是一种非自然形式,是历史、理念、政治斗争交汇产生的结果,同时指出在西欧国家中,法国是世俗化表现最为激烈的国家;第三部分,通过分析法国天主教在世俗化之后的现代定位(包括组织定位、思想定位和文化定位),说明即使在法国被公认为完全世俗化的国度里,宗教仍然具有不可忽视的地位和影响。与现代化相结合的世俗化理论值得作出重要的修正。  相似文献

The two authors have carried out an oral survey on a group of retired farm labourers in the French Vexin and the Pays de France regions (north of the lle de France). This paper examines the means by which individual memory registers the collective downward trend of this social group. It is remarkable for instance that respondents tend to recall memories of the “life of yore”;, opposed to life nowadays, instead of describing precise stages of their career, or the social evolution of their group and of the region. Their vision of History is fatalistic, syncretical, motionless, with frequent reference to war, exodus, moments of horror. All these elements express indirectly how a social group was crushed. Fragments of oral litterature that were collected on the same occasion refer also to the theme of social failure.  相似文献

The lithic assemblage from the Middle Palaeolithic site of Payre (Rhone Valley, France) contains a large number of convergent tools and pointed tools of various shapes, sizes and retouch types. These were excavated from several archaeological units, dating from marine isotopic stages 8–5, which also yielded human skeletal remains. Consideration of this large tool kit has led to an improved analysis of Middle Palaeolithic tools with two retouched convergent edges. The 350 tools were not described within the classical typological framework, but, rather, from a lithic technological perspective in relation to a discoid debitage. In addition, an initial macroscopic use-wear analysis aided in establishing whether they were used according to their technical and/or morphological features. The Middle Palaeolithic convergent tools from Payre are shown to be quite diversified, and the question of the significance of the retouch and the definition of the various types is addressed. Initial functional results indicate that a clear relationship between shape and function cannot be easily established, and that these tools were used as hand tools. This study contributes to the debate on the use of stone tip spears in the Early European Middle Palaeolithic.  相似文献

Wright, A.J., Plusquellec, Y. &; Gourvennec, R., February 2016. Devonian operculate corals (Calceolidae, Cnidaria) from the Massif Armoricain, France. Alcheringa 40, xxx–xxx. ISSN 0311-5518

The operculate coral Calceola gervillei Bayle, 1878 Bayle, E., 1878. Fossiles principaux des terrains de la France. Explication de la Carte Géologique de France 4(1), 1158. [Google Scholar] is described for the first time on the basis of the type material from the Cotentin region of Normandy (North Armorican Domain), from Early Devonian (likely upper Lochkovian to lower Pragian) strata, and is chosen as the type species of the monotypic new genus Gerviphyllum. The new genus is also present in the l’Armorique Formation (lower Pragian) of the Plougastel Peninsula (Central Armorican Domain) as Gerviphyllum sp. cf. G. gervillei. One locality in the upper Emsian (Polygnathus serotinus Conodont Zone) Le Fret Formation, on the northern coast of the Crozon Peninsula, has yielded operculate coral specimens described here as ?Chakeola sp., the first (tentative) record of the genus outside eastern Australia, south China and Vietnam. The operculate coral Calceola collini sp. nov. is described from six localities in the early Middle Devonian (Eifelian: Polygnathus costatus Conodont Zone) Saint-Fiacre Formation of the Plougastel and Crozon Peninsulas (Central Armorican Domain), despite the fact that knowledge of the internal characters, especially of the operculum, of the type species Calceola sandalina is very limited. From an extensive review of published references to Calceola from France, we conclude that only the record of Collin (1929 Collin, L., 1929. Un nouveau gisement à calcéoles dans le Dévonien de la Presqu’île de Crozon (Finistère). Bulletin de la Société Géologique et Minéralogique de Bretagne 7(3/4), 201208. [Google Scholar]) is valid.
