Lichenometric constraints on the age of the Huashan Grottoes, East China

Lichenometry is a method of dating that has been widely used in glaciated areas for determining the minimum age of exposure of a geomorphic landform during the late Holocene. This paper presents a regional calibration data set of lichen thallus sizes versus rock surface ages for the Huashan area, East China, based on measurements of yellow-green Rhizocarpon lichens on the known-age substrates at eight sites. An empirical relationship between thallus sizes and rock surface ages was established using both the traditional regression and the Bayesian approaches. Using the Bayesian calibration, the minimum age of the Huashan Grottoes was dated from 450 ± 60 to 330 ± 60 years ago, corresponding to the late Ming Dynasty (AD 1477–1632). These dates are generally consistent with those predicted from the regression-based linear growth curve. Our results suggest that applications of this technique can be safely extended to the non-glaciated areas.     

DEMOGRAPHIC CHANGE AS A FUTURE CHALLENGE FOR CITIES IN EAST CENTRAL EUROPE

Contemporary cities in East Central Europe (ECE) represent a hybrid type of urban development which is still generally considered to be a special case and is only exceptionally referred to in the recently intensified debate over the European city. Our paper argues that such exclusion is short‐sighted because ECE cities face structural problems similar to those of their Western pendants. Therefore, the contextual frame of urban research needs to be widened and can no longer be restricted to post‐socialist transition. In this regard, one of the main challenges for future urban development will be the consequences of demographic change. Ageing, new patterns of fertility behaviour and more diversified household structures in line with the Second Demographic Transition (SDT) will have significant implications for urban structures and housing markets, as already known for Western Europe. The purpose of this paper is to work out new questions and hypotheses for future urban research with special respect to Polish and Czech cities. Besides West European experience, recent developments in eastern Germany are taken as a frame of reference, assuming that this specific transition case may, in many respects, be regarded as a forerunner for similar developments in its neighbouring countries.

简析中日能源联合议价的成本收益

作为世界第二和第三的大能源消费国,中国和日本在分散竞争的条件下承受了过多的进口成本。本文在分析能源商品的价格决定因素基础上,探讨中日两国进行能源联合议价的成本与收益。认为这种努力可以在消除能源的亚洲溢价、减少能源竞争成本、促进亚洲能源期货市场发展、增强区域经济联系等方面获得显著收益。同时,联合议价的经济成本比较小,国家安全成本和政治成本则在两国之间存在不对称性,并且难以量化。     

鄂、西鄂、东鄂辨证——兼论湖北称鄂之由来

基于考古资料并结合前人研究成果,梳理了乡宁之鄂、沁阳之鄂、随州之鄂、南阳之鄂的地望变迁。西周早期为南控南淮夷、荆蛮,周封鄂于今随州。周夷王时,将鄂迁徙到今河南南阳市宛城区新店乡西鄂故城一带,周代南土防线亦随之收缩。约在春秋早期楚将南阳盆地纳入政治版图之时鄂国已消亡。战国中期前后,西鄂为楚封鄂君之地。垂沙之役后,鄂君东迁大冶鄂王城,始有东鄂。秦及汉初于东鄂故地设鄂县,其后又在南阳鄂国故地设县,因江夏先有鄂县,故称南阳之鄂为西鄂。湖北简称鄂与西周时期随州鄂国或南阳西鄂并无直接关系,而是与行政区划变迁及武昌九省通衢的地位日渐重要有关。武昌有“鄂”之别称,是湖北省简称鄂的直接原因。     

"文革"中的知识青年上山下乡运动研究述评

"文革"中的知青上山下乡运动是当代中国的重大事件之一.中外学者对这场运动进行了深入的探讨研究,取得了不少成果,发表了一批论文及专著,整理和公布了许多资料,目前在许多问题上已达成共识,与此同时也存在很大分歧,如关于"文革"中的知识青年上山下乡运动的基本动因问题、历史进程及其评价问题,对知青"返城风"及上山下乡运动终止原因等等,这些都有待研究者进行深入细致的研究.此外,在研究中还存在资料收集困难、研究力量薄弱、研究方法单一等困难与不足.     

Sensitivity of Dental Phenotypic Data for the Identification of Biological Relatives

Using modern samples of known kin, this paper evaluates two fundamental aspects of kinship analysis in archaeological contexts: (1) choice of data (dental metrics or morphology) and (2) analytical approach (multivariate, distance‐based approach or a ‘rare trait’ analysis). Stone dental casts were analysed from 155 female individuals from four sampling locations in Kenya. Of these 155 individuals, only three pairs were close kin: mother–daughter, sister–sister, and first‐cousin–first‐cousin dyads. After variable winnowing, inter‐individual distances or similarities were calculated using 11 odontometric variables and 25 dental morphological variables. Resulting distance matrices were ordinated in two dimensions using multidimensional scaling. Odontometric data performed relatively well at identifying known relative pairs, but the results were heavily affected by choice of similarity measure (e.g. Euclidean distances vs. Gower coefficients) and pre‐analysis data treatments (e.g. raw data vs. principal components). Dental morphological data performed comparably with odontometric data but were slightly less effective. Rare traits were identified and compared among relative pairs for concordance, with mixed results. Rare morphological features were randomly distributed throughout the population and were not exclusively found in close kin. In combination, results indicated the sister–sister dyad was most consistently identified; however, in no analysis were relatives more phenotypically similar than all random pairs of unrelated individuals. A multivariate, distance‐based approach was more effective than rare traits at identifying relative pairs, but even under ideal circumstances, there is not enough variation present in the dentition to faithfully identify close relatives in the absence of contextual archaeological data.

Stable Isotope Record of Human and Sheep Enamel Carbonate from the Ancient Middle Euphrates Valley (Syria)

Stable isotope analyses of human tooth enamel have allowed us to reconstruct the isotope composition of dietary carbon, changes in the oxygen isotope composition of drinking water and the possible migration of humans in ancient Terqa and Tell Masaikh (SE Syria). δ¹⁸O_carbonate values of human tooth enamel from the interval comprising the Neo‐Assyrian to the modern Islamic periods (from 900 BC to AD 1949) generally mirror the isotope composition of Euphrates water, which is believed to have been a major drinking water source. Lower δ¹⁸O_carbonate values of human Bronze Age apatite are linked to a different hydrologic system that was present in the Middle Euphrates valley at that time (2650–1700 BC). Higher δ¹⁸O_carbonate values of some individuals in the Neo‐Assyrian (900–700 BC) and Islamic periods (AD 600–1200) may indicate human migration from the interior of the Near East. Low δ¹³C_carbonate values (−11.3 to −12.4‰) of human tooth enamel from the interval comprising the Early Bronze to the Islamic periods (from 2650 BC to AD 1200) indicate C₃ plants as a predominant source of dietary carbon. Changes in human dietary customs in SE Syria (with inferred usage of C₄ plants) occurred in the modern Islamic period only (AD 1850–1949). Oxygen and carbon isotope data of sheep enamel show the usage of water bodies characterised by an enhanced evaporation rate during the Neo‐Assyrian time (900–700 BC) and grazing sheep herds on drier areas during the Islamic and the modern Islamic periods (after AD 600).

中国俄国史研究百年检视与思考

中俄交往始于蒙古西征和金帐汗国时代(1238-1480年),中国学人撰写俄国史自1878年刊印的鹭江奇迹人的《俄国志略》,到今天已经有整整140年的历史。中国的俄国史学科伴随民族命运、国家危机以及世界形势的变化而生,自诞生之日起即负有学人情怀、民族重任和学术职责三重使命。因此,俄国史学科在中国一直发挥着“知夷”和“盗火”的两大作用。中华人民共和国成立后,俄国史(包括苏联时期和俄罗斯联邦时期)研究获得了70年的巨大发展,主要成就有:1985年中国苏联东欧史研究会成立(1992年英文更名为中国俄罗斯东欧中亚史研究会),高等院校、社会科学院、党校、国家有关部委及党政机构纷纷设立俄国史或俄罗斯问题研究机构,建立了从历史学学士、俄国史硕士到俄国史博士的三级专业人才培养体系,俄国史和俄罗斯问题研究的专业期刊创立并连续出版,大量的俄国通史、中俄(中苏)关系史、专题著作、各类教科书、翻译著作(来自俄文、英法、法文、德文、波兰文等)出版,中国俄国史学者积极参与国际学术会议和国际合作研究,具有中国特色的中国“俄罗斯学”新学科正在建立过程中。     

Losing the Blanket,Building a Fence: Australian Anxiety and the End of Military Colonialism in Malaysia

From 1955 to 1988, the Royal Australian Air Force (RAAF) maintained a large airbase in Northern Malaysia. For the first 15 years of its existence, RAAF Butterworth had a modest and incomplete perimeter fence. With the end of British military colonialism in Malaysia and Singapore following the implementation of the ‘East of Suez’ policy, the Australians became preoccupied with their physical security and the role of the perimeter fence. By exploring the adoption of practices of exclusion via physical barriers in the wake of British withdrawal, this paper argues that the changing psychological outlook of Australian military officials reflected broader Australian anxieties about their own sense of ‘Britishness’ and the nation’s place in a decolonising Asia. As the Australians lost their British ‘blanket’ they built a fence.
