In a talk given at Zurich in the late 1940s, Hermann Weyl discussed Ferdinand Gonseth's dialectical epistemology and considered it as being restricted too strictly to aspects of historical change. His experiences with post-Kantian dialectical philosophy, in particular Johann Gottlieb Fichte's derivation of the concept of space and matter, had been a stronger dialectical background for his own 1918 studies in purely infinitesimal geometry and the early geometrically unified field theory of matter (extending the Mie-Hilbert program). Although now Weyl distantiated himself from the speculative features of his youthful philosophizing and in particular from his earlier enthusiasm for Fichte, he again had deep doubts as to the cultural foundations of modern mathematical sciences and its role in material culture of high modernity. For Weyl, philosophical «reflection» was a cultural necessity he now turned towards Karl Jaspers' and Martin Heidegger's existentialism to find deeper grounds, similar to his turn towards Fichte's philosophy after World War I. The discussion in the late 1940s can be read as a kind of post-World-War-II «Nachtrag» to Weyl's more widely known philosophical comments on mathematics and the natural sciences published in the middle of the 1920s.  相似文献

明清时期,松江府是全国的棉纺织业中心。从劳动生产率、劳动时间和劳动力数量等角度考察,明代晚期,松江府棉布产量最多为1575万匹,外销量最多为1305万匹;清代中叶产量最多为3000万匹,外销量在2600万匹左右。明代“松江棉布,衣被天下”,只是市场有效需求不足的结果。清代松江棉布销售区域大大压缩,并不是市场竞争的结果,而是基于其生产能力、运输成本以及与外地经济联系的结果。  相似文献

基于居民移动-活动行为的城市空间研究   总被引:16,自引:0,他引:16

在以人为本及后现代思潮的大背景下,人文地理学研究越来越关注个体人的行为以及生活质量问题,基于居民移动-活动行为的城市空间研究正成为人文地理及城市规划学等学科的焦点。论文在对城市活动空间研究及城市交通出行研究中的问题进行梳理的基础上,提出一个基于居民移动-活动行为的城市空间研究新框架,强调行为与空间之间的互动关系,强调RP法和SP法的结合,强调现实行为、现实空间与理想行为、理想空间之间的和谐。  相似文献

本文对国外旅游界最具影响力的两大旅游研究刊物Annals of Tourism Research(ATR)(1974—2005)和Tourism Management(TM)(1980—2005)中运用计量经济分析方法的122篇文献进行了全面回顾。在对计量经济分析方法的构成情况及应用领域进行统计分析的基础上,对其在国外旅游研究中的应用演进情况做了归纳和概括。研究发现,计量经济分析方法正逐渐成为国外学者进行旅游研究的主要手段之一,其中回归模型、时间序列模型和面板数据模型是最常用的手段;方法的应用主要集中在旅游需求研究方面,其次是旅游产业与环境关系研究、旅游供给研究。从研究方法的应用演进来看,经过30多年的发展,从静态的零星运用到比较系统的、动态的多种方法的整合运用,计量经济分析方法在旅游研究中的应用日渐成熟。  相似文献

A team comprising a former Russian policymaker and American analysts of the current Russian energy policy examines the course of that policy and its limitations during the post-Soviet period. In the process, they critically analyze key problems in Russia's oil, gas, coal, and electricity sectors that represent a potential drag on growth of the entire Russian economy and at the very least call into question the sustainability of further increases in exports to the West. The authors explore in considerable depth and detail both the factors underlying the recent increase in government intervention in the energy sector and the likely consequences for domestic production, consumption, resource security, and critical exports.

This paper examines how a group of Hong Kong working mothers use the internet in performing and realizing their paid work and domestic role identities. The internet is a technology-enabled space and also what Michel de Certeau calls a ‘practiced place’, where its nature and functions are necessarily determined by the actions and practices of agents. Through participant observation and the analysis of a sample of chatroom and forum messages from a user-driven Hong Kong-based parenting website called Happy Land, I examine the relationship between this virtual space and its users. I find that the website has developed beyond its technology-mediated nature into a community of face-to-face friendships and social and emotional support. In effect, this virtual space plays a role in the social reproduction of the contemporary dual-earner family by enabling working mothers who use the website to perform roles in production and reproduction respectively.  相似文献

南宋临安节日活动的时空结构研究   总被引:1,自引:0,他引:1  
在城市地理学研究中,由于缺乏有关历史城市物理空间的基础性研究工作及受研究资料所限等原因,关于历史时期的城市居民生活空间方面的研究较少开展。本文选择南宋时期的临安作为城市空间研究对象,在全面梳理相关历史文献记载的基础上,尝试结合目前应用最广泛的功能分区法和时间地理学两种方法,对南宋临安节日活动空间进行剖析,揭示其城市节日活动的时空间结构特征。同时,文章还探讨了城市社会空间的形成机制,提出物理空间奠定了临安节日活动空间的基本格局、都城地位是临安节日活动空间形成的控制因素、城市经济主导了临安节日活动的空间分异过程等结论。  相似文献

The physical spaces of imperial education during the Qing were carefully constructed sites of political architecture that sought to shape the behavior of princes, emperors, and their teachers while projecting dynamic images of power. This article examines a range of buildings associated with the Qing pedagogical apparatus. It argues that the changing spaces of imperial education drew on both classical ideals and international iconographies of power to create and disseminate a fluid vision of rule. In the eighteenth century, the Qianlong emperor ordered the construction of the Biyong Hall at the center of the Imperial Academy in Beijing for exclusive use by the emperor during the Imperial Lecture, combining classical Han Chinese and Manchu expressions of authority. Throughout the nineteenth century, heirs to the throne and young emperors were trained in classrooms filled with calligraphy penned by their ancestors. Aphorisms drawing on the Confucian classics, as well as Daoist and Buddhist texts, urged the young rulers to strive for dynastic renewal. Finally, at the start of the twentieth century as the Qing worked to transition to a constitutional monarchy, imperial classrooms around Beijing were infused with Western architectural styles, incorporating new strands of authority for the reforming Qing dynasty.  相似文献

This paper examines the rural ethnic heritage-inspired transformation of the built environment of a relatively small county town in China. The paper explores the ways village-based ethnic heritage is being repositioned by local leaders as a resource for tourism-oriented revenue generation and for ‘improving’ the ‘quality’ and behaviour of town residents. Viewing heritage as a ‘technology of government,’ the paper provides an analysis based on three interrelated themes: the discourses by which town leaders and planners have conceived the heritage development project as one of improvement, the spatial practices by which those discourses have been realised in the built environment, and the ways residents themselves have appropriated and ‘inhabited’ this new ‘villagized’ city as they go about their everyday urban lives. Based on ethnographic field work, a survey, and extended interviews over a period of four years, the paper finds the town leadership’s faith in the ability of the built environment to shape and improve the conduct of citizens to be overstated. While the town’s transformation has generated a new sense of urban modernity among residents, their ways of inhabiting and using urban space have little relevance to the ‘heritagized’ environment in which they now live.  相似文献
