对唐代贾耽的地理(地图)著述的名目进行辨析,分析了"关中陇右及山南九州等图"、《九州图》、《海内华夷图》之间的关系,以及别录与通录的区别。指出《九州图》、《海内华夷图》是贾耽国图撰修总体事业在不同历史阶段的总称。并从地图学传统、方志学传统入手,探讨了贾耽地理(地图)著述的性质,对其中的地图学成绩进行了重新评价,进而从"近意就实,依稀像真"分析了贾耽地图学的滞后性,指出"古墨今朱"应只是文字注记的区别,并非通过图形绘制表达古今地理要素的差异,由此审视了中国古代地图史上图形绘制与文字注记的关系。 相似文献

The 2000 Presidential election was plagued by butterfly ballots and ‘pregnant chads’. Electronic voting systems, lacking verifiable paper trails that are subject to possible fraud, promise to wreak havoc with the 2004 Presidential election. There is a great diversity of systems of voting technology in the 50 states: from paper ballots, lever‐operated machines and punch cards to optical scanners and electronic systems. Associated with each technology is an estimated error rate. The underlying theory of this paper was set forth by William F. Ogburn in his famous book entitled Social Change, published in 1922. Dividing culture into material and non‐material elements, Ogburn argued that non‐material elements lag behind material elements. His explanation for this lag is that technology, which underlies material culture, changes at a faster rate than elements of non‐material culture. Obgurn did not contemplate the possibility of a reverse lag, viz., technology lagging behind non‐material culture. In analyzing the anomalous relationships between voting technology, political institutions and legal institutions, a striking instance of a ‘reverse cultural lag’ is discerned. To eliminate the phenomenon of the reverse cultural lag, there is a need for a federally‐funded program of a uniform, state‐of‐the‐art voting technology, plus an amended Help America Vote Act, to implement the innovations in the 3,114 counties. The complex problems reviewed in this paper point to a vexing question: how do we educate an electorate in a democratic society—such as the United States in the twenty‐first century—to be responsible for ensuring that periodically‐elected representatives implement the will of the people? 相似文献

Despite the fact that virtually no Chinese maps have survived from the first millennium, it is nonetheless possible to reconstruct a rich context associated with their production, use and perception from a variety of written sources. Three cases from the Tang dynasty (618–907 ce) are presented in this article in which the characteristics of the missing maps emerge through their associated texts, which have outlasted them. These examples include two documents that once accompanied maps presented to the emperor and an anecdote that refers to a map of the remote southern frontier. They demonstrate that the maps were designed not only to encapsulate imperial territory but also to serve as guideposts for aspirational travel. They were also perceived by their users as invitations to experiences both desirable and undesirable. 相似文献

“生态环境”用语产生的特殊时代背景 总被引:3,自引:0,他引:3
侯甬坚 《中国历史地理论丛》2007,22(1):116-123
本文随着地理学家黄秉维院士的回顾,对1980-1982年五届全国人大宪法修改过程中,将草案中的“生态平衡”改为“生态环境”一词、并写入宪法的过程,再现出来予以分析讨论,认为“生态环境”概念提出的背景是全球和中国谋求环境保护事业发展的时代潮流,侧重的是人民生存于其中的自然环境的生态质量,具有积极的社会昭示作用和教育意义,不宜仅从学理上认为“生态环境”的提法有错,因为真实的世界往往比学者头脑中的理论思维更精彩。学术界于2005年5月展开的对“生态环境”、“生态环境建设”概念的研讨,贡献了许多真知灼见,然而,从“生态环境”一词在人大常委会产生过程的基本事实判断,它属于具有相对独立性的政府用语(法定名词),而非严格的科技名词,主要使用于国家行政管理层面,而学术研究中则主要是尊重学者自己的理解和创作。至于如何健全政府用语、消除政府不当用语在国家社会生活中可能带来的负面影响,正是学术界应该积极探讨的问题。 相似文献

An analytically solvable core-periphery model 总被引:19,自引:0,他引:19
We develop an analytically solvable version of the central modelof new economic geography, the so called core-peripherymodel by Krugman. While the modified model reproduces all theappealing features of the original one, it also allows us toobtain additional analytical results that are out of reach inKrugman's set-up. First, we are able to assess the exact numberof equilibria and their global stability properties. Second,we are able to investigate the implications of exogenous asymmetriesbetween countries. This is achieved by introducing heterogeneitybetween high-skill mobile and low-skill immobile workers, whichmay also be an empirically attractive property. 相似文献

谁是鲁国的始封之君 ,周公旦抑或其子伯禽 ?自古至今聚讼未决。今天的学者多主“伯禽封鲁”说 ,其主要依据为《鲁颂·宫》与《左传》定公四年所载的两条材料 ,但这两条材料明显有可疑之处。“伯禽封鲁”说之所以影响大 ,盖由崔述的鼓荡所致 ,然而崔氏的考证远非一贯正确。《左传》僖公二十四年说“鲁”是“文之昭”,这是一条铁证 ,证明了周公旦是鲁国的始封之君。历史上 ,周公旦曾两次封于鲁。但由于他是武王、成王两代人的助手 ,所以两次受封均不曾就国 ,而是由其长子伯禽代就封 ,故有“伯禽封鲁”说 相似文献

ABSTRACTSustainable nature-based tourism was brought to the public's attention as a solution to the problem of economic diversification in Central and Eastern European (CEE) communities included in European Ecological Network – N2000. However, Natura 2000 tourism development has not yet proven to be an effective way to boost local economies and the notion of sustainable tourism based on Natura 2000 resources has been challenged by residents of the CEE communities. The study goal was to explore issues concerning Natura 2000 tourism from the perspective of local residents within three municipalities of Ma?opolska in Poland to determine if Natura 2000 is perceived by local residents as a valuable tourism asset. We employed a mix-mode methodology: an in-depth interview and public participation GIS mapping task. The study results highlight several areas of concern regarding resident perspectives of Natura 2000-based tourism: first, the misconception that residents need and want nature-based tourism when other economic activities provide sufficient income; second, the misconception that Natura 2000 is considered a valuable asset when other tourism attractions in a municipality attract more visitors; third, the residents misconception of nature-based tourism itself; and last but not least the importance of engaging with residents when assessing the potential for Natura 2000 tourism. These findings can assist policy-makers and tourism managers with prioritizing avenues for further action. 相似文献
