Freeze‐thaw cycles are most common at the beginning or near the end of the winter season. These cycles have various effects on the ecosystems of Eastern Canada, affecting both biotic and abiotic components of temperate cold environments. Using air temperature minima and maxima from four meteorological stations close to Québec City, we determined the frequency of daily freeze‐thaw cycles for the last 30 years. The results show no significant increase in the number of freeze‐thaw cycles despite a small increase in air temperature. Polynomial curves describing the relationship between mean air temperatures and the number of freeze‐thaw cycles were calculated. Based on these equations and anticipating a climate change scenario, we projected future freeze‐thaw cycles. Assuming a 5 °C increase in mean air temperatures by 2100, we estimated that the number of days with a freeze‐thaw cycle could increase by approximately 20 days per winter. The increase in the number of such cycles will be concentrated during the coldest months of the winter (January and February). 相似文献

Chenque I site is a prehistoric cemetery located in Lihué Calel National Park (La Pampa province) in the Western Pampean region of Argentina. Hunter‐gatherer societies made use of this site during the Final Late Holocene for at least 700 years (1030–370 BP). Currently 41 burial structures have been excavated, and more than 150 individuals have been recovered. There is great variability in mortuary patterns at the site (simple, multiple, primary, secondary burials, and also a variant not previously observed in the region). The life‐ways of this population have been investigated through the evaluation of several biological and cultural factors. Several pathological conditions have also been identified in this cemetery. Burial no. 12 contains a skeleton of an adult male that shows multiple pathological lesions, compatible with a neoplastic disease. These lesions have been analysed using several methodological strategies: macroscopic, radiological and microscopic. This is the first time that this kind of disease has been identified from a prehistoric burial in Argentina. In this paper the location and characteristics of the lesions are evaluated, and the different neoplastic diseases that could have produced them are discussed. Since the people buried in this cemetery belonged to highly mobile societies, a key issue is to infer the consequences that this disease would have had on the dynamics of the group in which this person lived, because of the gradual deterioration of his health and physical strength.

The word ‘stromatolite’ should only be applied to organosedimentary structures predominantly accreted by sediment trapping, binding and/or in situ precipitation as a result of the growth and metabolic activities of benthic, principally prokaryotic, micro-organisms. Structures of uncertain origin that resemble stromatolites should be called ‘stromatoloids’. This cautious approach would eliminate the currently common assumption that structures with mesoscopic morphological similarities to microbially accreted sedimentary structures must be biogenic, a misconception that hampers investigations into the antiquity of life. A hierarchical series of meso- and microstructural attributes of stromatolites can be used to assign gradually increasing probabilities of biogenicity to stromatoloids. This method is particularly useful for interpreting ancient noncolumnar stromatoloids with poor microstructural preservation. In a range of Early Archaean pseudocolumnar, nodular and stratiform stromatoloids from North Pole studied using this method, none could be proved to be stromatolites and only a few are probable or possible stromatolites. As these stromatoloids closely resemble previously reported structures from North Pole interpreted as stromatolites, we consider that the evidence for the existence of life c. 3500 my ago at North Pole is less definitive than previously supposed. 相似文献

This article considers the regional order-building challenges that Australia presently confronts in the Indian Ocean region (IOR). The author argues that while regional stability within the IOR constitutes an increasingly important Australian security interest, policy makers will struggle to translate the order-building strategies they have previously pursued in East Asia into an Indian Ocean context. In East Asia, Australia has historically pursued a ‘dual track’ order-building strategy centred on its participation in a US-dominated ‘hub and spokes’ alliance system alongside multilateral regional engagement. The absence of an equivalent alliance system or an established tradition of multilateral security diplomacy conversely precludes an extension of this strategy into the IOR. Growing tensions between the USA and China and between China and India, meanwhile, further complicate IOR security dynamics, while underscoring the urgent need for a more coherent approach to regional order-building. With these challenges in mind, the author concludes by proposing a range of bilateral, minilateral and multilateral initiatives that Australia should pursue to stimulate the emergence of a more cooperative IOR security environment. 相似文献

In northern Ghana periurban areas are encroaching on rural areas and agricultural land ends up being sold for residential purposes mainly by chiefs and “earth” priests. The changing customary land tenure systems have generated a state of uncertainty and tension as the title and responsibilities of titleholders are subject to the interpretation by those who administer custom. Increasing commodification is taking place that benefits an emerging political‐traditional and economic elite. The centralized systems restrict the benefits of the commoditization process mainly to chiefs and their collaborators, whiles acephalous systems allow more space for objections and struggles by those whose land is expropriated. Neoliberal development policies have shaped the commodification of land and entrenched existing socio‐economic inequalities that marginalize the poor who are unable to seize the opportunities of the emerging urban economy. 相似文献

1941年太平洋战争爆发前后,日本在国际上更加孤立。在物资贫乏、战争迁延日久、军需储存消耗殆尽、兵源枯竭及劳动力缺乏的情形下,日军对华北的依赖性日益加大。在华北,丰富的资源和广大的人力散布在农村,而农村又掌握在中国抗日革命的势力手里,华北日军只控制着寥若晨星的点和线。华北日伪通过\"村政建设\"向敌后抗日军民展开农村争夺战。\"村政建设\"主要源于中国历史上统治者控制乡村的统治术,也仿效了日本和伪满洲国的\"街村制\",体现了日伪利用中国旧有制度,实行法西斯统治的狡诈性。其目的在于根绝共产党及八路军抗日活动的民众基础。随着日军无条件投降,华北日伪的\"村政建设\"彻底破产。 相似文献

During the transition towards a more market‐oriented economy and entrepreneurial governance, local authorities have attempted to create new cross‐jurisdiction regional entities to enhance their competitiveness through making city‐region plans or regional strategic plans in China. This article analyses the process of region building in China through a case study of Nanjing city‐region. We argue that region building is a state‐led regional project in China, not a spontaneous process. City‐region planning has played a legitimacy‐seeking role in the construction of new regions. Based on the discourse provided by the city‐region plan, associated city networks are being created as a mechanism for plan implementation and regional coordination. This signals that regional planning is entering the stage of regional institution building. By assessing the capacity of regional institutions, we argue that the newly‐emerged regional institutions or urban networks have facilitated regionalization in terms of the increasing involvement of non‐state actors, the formation of regional coherence and identity and the enhanced inter‐city co‐operation. However, it is still difficult to establish effective regional governance due to competing local governments, the arbitrary political leadership and the fragmented planning functions. 相似文献

Regions have been regarded as processes, artefacts and discourses, and recently as ‘brands’ that various stakeholders use in marketing. Discourses on institutional regions are typically promoted by media, governmental bodies and planning organizations that draw on reputed collective regional identities—the expressions of past and current social discourses and cultural practices. However, such institutional regional discourses are often incongruous to spatial imaginaries of everyday life. This article scrutinizes the meanings of spatial attachment to citizens and explores to what extent regional identities are meaningful in everyday life. To avoid biased assumptions, focus-group interviews were carried out within four Finnish provinces among the members of four social movements. The results show that provincial spaces are not actively thought-and-practiced. Spatial identities are rather structured around personal experiences that typically accumulate in several locales, since personal histories are increasingly characterized by mobility. This article also recognizes that the everyday meanings of a socially constructed region are often generationally read and combine different historical narratives. 相似文献
