清代伊克昭盟的人口数字,尤其是蒙古族的人口数字一直比较模糊。一是因为史书缺乏记载,二是民国以来相关研究太少。相关学者在涉及这一问题时或者避而不谈,或者仍沿用民国时期贺扬灵的估计数字。作者在做相关课题时也涉及到这一问题,并发现贺扬灵的人口估计方法值得商榷。本文以1650~1850年为研究时段,以蒙古人为研究对象,以讨论丁的性质和户均人口为切入点,运用现代人口学的研究方法并结合相关资料,对清代前中期伊克昭盟的蒙古族人口进行复原研究,得出的结论是:1650年人口为14万左右,1750年为17万多,1850年为21万多,达到人口高峰。  相似文献

Drawing from fieldwork conducted to examine the roles played by ferry mobilities in the lives of residents of ferry-dependent islands and coastal communities of British Columbia, Canada, this paper focuses on three elements of spatial mobility assemblages: motives, costs, and frictions. In doing so, this paper contributes to the growing literature on the politics of mobility constellations. Data shed light on the transformative, but contested, power of spatial mobilities. To analyze these dynamics the analysis builds upon Ingold's ideas on wayfaring to highlight how practices, representations, and experiences of ferry mobility exercise their transformative power.  相似文献

An intensive investigation of China's high-tech sector led by a noted Hong Kong—based geographer examines the patterns of cooperation between firms and local governments (so-called "state-firm strategic resonance") as an alternative to knowledge spillover in an effort to explain why certain firms are more likely to innovate than others within an economic cluster. As a case study, they select the integrated circuit design industry (a key in the development of more efficient computing and thus a critical element of the digital revolution) in Shanghai, one of the most advanced metropolitan regions in China. A systematic analysis of firm-level data obtained inter alia from the authors' 2008 survey and interviews revealed a significant pattern of variation in innovation that could not be explained by inter-firm interactions in the process of industrial clustering. The authors argue that the uneven pattern of technological innovation is contingent on a state-built institutional and market environment designed to stimulate firms' innovative activities, and demonstrate how firms respond to that environment in a Chinese metropolis.

Based on Max Weber's concept of Kulturnation and Hans Blumenberg's project of metaphorology, this essay argues that modern nations follow distinct cultural programmes that are inherent to their national ideas. Each national idea is propagated by a particular biopolitical metaphor, which performs a transfer from practical or scientific ideas about how nature structures and organises life to cultural ideas about how human lives should be socially and politically organised. The essay examines the emergence of the principal metaphors of grafting in England (Great Britain), of regeneration and elective affinities in France, and of organic self-generation in Prussia (Germany). The fact that each nation claims for its particular national idea the status of a universal principle constitutes the intrinsic paradox of nationalism.  相似文献

This paper explores the relationship between the presence and absence of Islamic communities in western Wales. Commencing with a discussion of the literatures on the geographies of Islam and rural exclusion, I argue that both sets have neglected research on rural religious communities. Discussion is centred upon the visual absence of Islam in the area, as local mosques are predominantly housed in contingent or non-purpose-built buildings. Using interview data, I examine the implications of these absences for local Muslims' experiences of rural landscapes, and discuss the juxtaposition between the visual absence of cultural indicators of Islam and the contingent strategies these communities employ to meet their religious needs. Adopting Nancy Fraser's concept of a subaltern counterpublic, I argue that the contingent presence in the landscape brings organisational possibilities. However, the lack of visibility of these counterpublics also brings challenges, fragmenting the community and creating difficulties for individuals to access particular services. This subterranean ontology has implications not only for liberal ideas of publicity and privacy, but also for inclusive citizenship in an era when debates about multiculturalism centre on accommodating religious needs.  相似文献

1931—1937年,关内向东北移民具有以下基本特点移民的数量少、波动大,移民运动一度中断;移民的流向和地域分布,以南满的城市和工业区为主;移民的居住年限下降,流动性增强。从移民的性别、年龄、职业及迁移过程等方面可以看出,1931年后关内与东北间人口的迁移与流动发生了根本变化,即进入东北地区的关内人口,不再是自由流入谋生,而是被作为“苦力”招骗而来,带有明显的强制性。  相似文献

ABSTRACT

Surface thermometers were developed in the latter half of the nineteenth century. From the 1850s through the 1880s, collaborations between physicians, research scientists, and instrument makers produced clear improvements in the technology to measure cranial surface temperatures, with development of self-registering mercury surface thermometers resistant to pressure and little influenced by ambient temperature, apparatus for recording cranial surface temperatures from multiple stations simultaneously, and development of thermoelectric apparatus. Physiologic studies of cranial surface thermometry were conducted over a quarter century from 1861 to 1886. Beginning in the 1860s Albers in Bonn, Germany, and Lombard at Harvard and later in England systematically investigated surface temperatures on the head using surface thermometers and thermoelectric apparatus; they demonstrated that head temperatures were variable over time and across individuals and were not clearly influenced by thinking or muscular contraction but were influenced by ambient air temperature. In 1880 Amidon in the United States claimed that cranial surface thermometry during exertion produced localized increases in surface temperature on the contralateral scalp in a specific pattern (“external motive areas”) indicating underlying brain areas responsible for each movement. Amidon’s results were not reproduced by experienced physiologists in England or France. Contemporaries recognized that significant technical and practical problems limited the accuracy and reliability of cranial surface thermometry. Physiological studies of cranial surface thermometry ended in the mid 1880s, although some clinicians who were early advocates promoted its use in clinical contexts into the early twentieth century.  相似文献

ABSTRACT

Surface thermometers were developed in the latter half of the nineteenth century. In 1877, Broca, already famous for his contributions to the cerebral localization of nonfluent aphasia, presented his first clinical observations on cranial surface temperatures: In two cases, cranial surface temperatures were decreased over a middle cerebral artery infarction, and increased in surrounding areas, which Broca attributed to “compensatory hyperaemia.” As Broca made apparent in a later report in 1879, he had used a “thermometric crown,” an apparatus consisting of six to eight large-reservoir mercury thermometers strapped against the head. Following Broca’s report, American neurologists reported cases in which cranial surface temperatures were increased either locally over a superficial brain tumor or globally with a cerebral abscess. Despite promising anecdotal reports, contemporaries recognized that significant technical and practical problems limited its accuracy, reliability, and clinical utility. Advocates never demonstrated that this technology provided significant marginal benefit to the medical history and physical examination. The technique fell out of fashion before 1900, though some early advocates promoted it into the early twentieth century. It was ultimately replaced by more effective technologies for cerebral localization and neurological diagnosis.  相似文献

Mobility—of people, products, and capital—is a common trope of the contemporary globalized world. Yet, mobility is not only a current phenomenon, but has an integral role in the constitution of past empires. In particular, the governance of empire requires the mobility of administrators and their families: people who, in the service of empire, travel between metropole and periphery, and even more typically, in the multiple circuits between peripheries. The life of Sir Anthony Musgrave, a colonial administrator who served in posts in the Caribbean, Canada, South Africa, and Australia, exemplifies the movement which empire demands. In their travels around the British world of the late nineteenth century, the Musgraves—Sir Anthony, his American-born wife Lady Jeanie, and their three sons—engaged with empire in ways both physical and conceptual. In this essay, I explore how the Musgraves’ mobility contributed to a sense of overlapping colonial worlds that were supported and challenged by the rise of communication and transport technologies, the flows of international labor, and the competing demands of national and imperial identities.  相似文献
