对明清江淮西部地区的旱涝史料进行梳理,对逐年州县旱涝灾害资料等级进行量化处理,并通过计算旱涝平均等级值和10年滑动平均值,重建1450—1911年该区域的干湿变化时间序列。结果发现,该区1450—1911年间共出现6个干湿阶段: 1450—1490年,以轻度干旱为主;1491—1545年,旱涝灾害频发,干湿波动较为明显;1546—1625年,旱涝灾害少发,干湿比较平稳;1626—1710年,以中度干旱为主,极端干旱事件发生频率显著增加;1711—1860年,气候湿润;1861—1911年,干湿波动偏湿润。不同的干湿阶段对江淮西部的湖泊也造成了一定的影响,干旱时期,湖盆积水减少,湖周萎缩;湿润时期,降雨增加,湖泊的蓄水量增加。  相似文献

Following the 1745 rebellion, agrarian capitalism rapidly transformed subsistence practices in the Outer Hebrides. Landowners increased rents, enclosed common lands, and replaced crofters and cattle with sheep-ranges. Population growth, the demise of the kelp industry, and crop failures compounded the problems of the peasantry. Widespread emigration commenced in the 1770s and peaked in the 1850s, when entire communities were exiled to British North America—the so-called Highland Clearances. This article traces the development of agrarian capitalism on the Isle of South Uist, explores the agricultural improvements undertaken by successive landlords, and considers modes of resistance adopted by the island's population.  相似文献

中国马克思主义史学发展道路的思考   总被引:3,自引:0,他引:3  
从五四运动到新中国成立前,自李大钊开始传播唯物史观,此后经郭沫若、吕振羽、范文澜、翦伯赞、侯外庐等的努力,马克思主义史学家坚持革命性与科学性结合,显示出自己建构研究中国历史体系的规模和力量,因而20世纪把中国史学推向了新阶段。建国后17年,马克思主义史学虽然经历过严重的曲折,但成绩仍是主要的,主要表现在:以唯物史观原理与中国实际相结合的方向得到坚持,形成百家争鸣的局面,在通史、断代史和专史领域以及大规模整理历史文献等方面都有重要成果;1958年以后教条化严重泛滥时,郭沫若、范文澜、翦伯赞等挺身而出进行抵制,一批熟悉历史考证的学者在唯物史观指导下,使史学达到新的境界。在改革开放的新时期,经过批判和反思极“左”路线危害,解放思想,史学出现了开拓进取、欣欣向荣的新局面。  相似文献

Harvesting different species as foods or raw materials calls for differing skills depending on the species being harvested and the circumstances under which they are being taken. In some situations and for some species, the tactics used are mainly behavioral—that is, people adjust, or adapt, their own actions to fit the behavior and circumstances of the species they are taking. Under other circumstances and for other species, the skills and tactics used may call for greater environmental preparation or manipulation. Therefore, instead of trying to distinguish people today and in the past as either foragers or farmers, it makes sense to define human subsistence behavior as an interactive matrix of species and harvesting tactics, that is, as a provisions spreadsheet.  相似文献

Mauermanshoek Shelter, in the Korannaberg of the eastern Free State, has traditional San hunter–gatherer rock art together with white finger-painted horsemen of uncertain authorship. The excavated material dates to between 3500 bp and approximately 200 bp. The lithic assemblages show little change throughout, but ceramics, glass beads, and domesticated animal remains appear in the uppermost levels. The issue of most interest is that of the shelter's occupancy in the last few hundred years. Historical records show that the ethnic composition of the eastern Free State was complex during this time and that there were both aggressive and cooperative interactions between the various groups. Kora pastoralists were notorious stock raiders and the secure identification of other people on the landscape was complicated by a tendency for early writers to call all raiders Kora. A combination of archaeological and historical evidence suggests that San occupied the shelter for most of its history but that Kora herders may have been responsible for the finger-painted horsemen somewhere between 1837 and 1851 when a Wesleyan Mission Station, Merumetsu, served the Kora of Korannaberg.La grotte de Mauermanshoek, située dans le Korannaberg, à l'est de la province du Free State, contient des peintres rupestres de tradition San, réalisées par des chasseurs/bergers, ainsi que des cavaliers blancs, peint avec le doigt, d'une origine incertaine. Le matériel qu'on a trouvé dans les fouilles daté d'une période entre 3500 bp et approximativement 200 bp. L'industrie lithique est très homogène sur l'ensemble du site, mais des céramiques, des perles de verre et des restes d'animaux domestiques sont présents aux niveaux supérieurs. L'occupation de l'abri pendant les quelques centaines d'années passées est d'un inérêt tout particulier. Selon les archives historiques, la composition ethnique de la partie est du Free State était, à l'époque, complexe et il y avait les interactions à la fois agressifs et coopératifs entre les groupes différents. Les pasteurs Kora sont bien connus pour leur réputation d'attaquer les troupeaux mais l'identification certaine des autres peuplades est compliquée par le fait que les premiers écrivains rapportaient tous les aggresseurs comme des Kora. Une combinaison d'indices archeologiques et historiques suggère que les San occupèrent cette grotte pour la plus grande partie de son histoire mais que des bergers Kora pourraient être à l'origine des cavaliers peints avec le doigt, probablement entre 1837–1851, la période durant laquelle une mission Wesleyan servait le Kora de la région du Korannaberg.  相似文献

学术界近年来关于知识分子问题的研究呈现三大特点:一,“体验中的理解”,利用研究主客体在血脉、情感上的亲密关系,勉力进入先辈生存的精神家园,以理解他们的所思所言所行;二,“建构中的阐释”,力求在某种独特、精致的理论建构中提出假设,表达观点完成叙述;三,“批判中的反思”,通过广义上的学术批判,对古往今来的士之论士、儒之论儒、知识分子之论知识分子的成果进行反思。此外知识分子研究的方法论问题,也值得引起关注。  相似文献

Archaeological research on disasters has increased substantially since Sheets's 1980 review of the topic, and with heightened media coverage and funding for the study of such events, archaeological interest will continue to grow. This paper examines how prehistorians have incorporated disasters into their research since 1980, using the literature on El Niño as an illustrative case, and assesses this work in relation to geographical approaches to disaster as well as concepts that have been developed within the new ecologies.  相似文献

A 19th‐century dog burial uncovered from a historical homelot in Toronto, Canada, provided a unique opportunity to reconstruct the individual's osteobiography. Of particular interest are the dog's very large size and a suite of skeletal pathologies. Recovery of a nearly complete skeleton combined with the use of X‐rays and micro‐computed tomography (micro‐CT) allowed for a discriminating differential diagnoses. Stable isotope analyses were applied to investigate questions of diet. Results reveal an individual who suffered greatly from disease towards the end of his life and hint at its owners attitudes towards dogs. The interdisciplinary approach applied to this case study highlights the potential information obtainable from pet burials. We argue that better analyses and reporting of pet burials will help address research questions targeting broader themes related to human–animal relationships.

Historians have taken a beating in recent times from an array of critics troubled by our persistent unwillingness to properly theorize our work. This essay contends that their criticisms have generally failed to make headway among mainstream historians owing to a little noticed cognitive byproduct of our work that I call history as philosophy. In so doing I offer a novel defense of professional history as it has been understood and practiced in the Anglophone world over the last half‐century or so while suggesting, in conclusion, that historians could not do other than they do without serious psychic and societal loss.  相似文献

Summary

The paper exposes the views of Ernst Cassirer and Martin Heidegger on the dynamics of the sciences of their day, as both developed them in the two decades after the encounter of the two philosophers in Davos in 1928. It emphasizes points of common concern, and it compares their positions to those of contemporary philosophers of science Gaston Bachelard and Edgar Wind.  相似文献
