互联网地理学研究已成为近年国际人文地理学研究的热点之一,但对网站注册用户空间分布的研究较少。本研究以世界最大的社交网站Facebook为研究对象,利用获得的2012年注册用户规模数据,具体分析其空间分布规律与影响因素。研究发现：①无论是在洲际层面还是国家层面,Facebook注册用户的规模与普及率分布都存在着巨大差异。其中前者的集中化指数高,且偏重发达国家和人口规模过亿的国家;后者则是欧美、大洋洲和高收入国家相对偏高。②Facebook注册用户规模主要受国家经济总量、人口数量和网民规模三个层面因素影响,普及率则主要受人均收入、人口层面的城镇化率、网民普及率和网络基础设施等层面因素影响。此外,上网工具变革、文化差异和网络监督制度也是影响其空间分布的重要因素。③由于成为Facebook注册用户的基本前提是其必须首先是网民,因此后者也相应成为影响前者空间分布最为直接的因素。其他因素主要通过作用网民进而实现对Facebook注册用户空间分布的影响。 相似文献

To study the complexities of race and geography, research and analysis should center on the fatally dynamic coupling of power and difference signified by racism. The author considers briefly the theoretical and methodological implications of key frameworks geographers used during the past century to account for racialized power differentials. To illustrate the political, economic, and cultural capacities that historical materialist geographical inquiry ought to consider, the author outlines the background for a new project—a case study of the U.S. during a period of unusually intense state‐building in the mid‐twentieth century. The article concludes that the political geography of race consists of space, place, and location as shaped simultaneously by gender, class, and scale. 相似文献

中国互联网发展的区域差异分析 总被引：19，自引：2，他引：17
互联网发展的区域差异及其与区域发展的相互影响研究已成为地理学研究中一个新的问题。从网络普及率、网络信息资源丰度及互联网商业应用三个角度初步探讨了中国互联网发展存在的区域差异,并设计了互联网发展指数(IDI)、从人均的角度反映互联网发展的综合水平。表明:东部地区的发展水平明显高于中部和西部地区,但与传统意义上的经济发展梯度不同的是,西部地区的互联网发展水平稍高于中部地区;中国大陆31个省、直辖市、自治区的互联网发展综合水平的差异同样显著,按照IDI值大小被划分为6个等级。互联网发展区域差异的影响因素是多方面的,应用多元回归分析方法研究发现,区域人口素质水平、区域信息和知识生产能力对我国互联网发展区域差异的解释能力最强,区域对外开放程度和区域城市化水平的影响也较显著。 相似文献

Abstract The geopolitics of the Cold War is illustrated by the diplomatic ties between countries, particularly the two superpowers and their respective allies. Specifically, the location of embassies abroad and those hosted by countries are examined to determine what they reflect about larger geopolitical issues. This article grew out of class projects used in introductory human geography courses to teach place name, library, writing, analytical, computer, and cartographic skills. The global patterns of embassy locations for all countries are first examined and then the particular patterns of the United States, the Soviet Union, and NATO and Warsaw Pact countries. A comparison between the location of U.S. and Soviet embassies shows that the Cold War was geographically visible only for “minor” states. The Warsaw Pact countries were ideologically more unified in the location of their embassies than the NATO countries. With the collapse of Cold War geopolitics, embassy locations are already changing, signaling major transformations to a New World Order. Geographers will need to monitor these newly emerging patterns and teach their students how to examine them. 相似文献

Geographies of the tropical Internet: An overview 总被引：3，自引：0，他引：3
Barney Warf 《Singapore journal of tropical geography》2007,28(2):219-238
The literature on the geography of cyberspace has focused heavily on the economically developed countries in the mid-latitude regions of the world. This paper addresses the spatiality of the Internet among countries located in the tropics. It charts the network of optical fibre lines that make access possible and the critical role played by telecommunications deregulation. It also accounts for the rapidly changing pools and explosive growth of Internet users between 2000 and 2005 in relation to the socioeconomic variables closely associated with access: costs, wealth, literacy and telephone penetration rates. Finally, the paper also looks at government censorship in various regional contexts and summarizes the status of e-commerce and e-government in different regions within the tropics. 相似文献

Abstract Innovation diffusion research has shown that users of innovations have identifiable characteristics that can be used to differentiate them from nonusers. This research classifies practitioners of Internet-based teaching in college geography and relates adoption patterns to faculty members' research specialty, place of employment, teaching experience, and academic rank. All variables except academic rank were related to faculty members' adoption of and approach to Internet-based teaching. The results of the study provide insight into how the Internet is being used to teach geography in higher education. 相似文献

Multiple geographies of the Arab Internet 总被引：1，自引：0，他引：1
The Arab world plays a relatively minor role in the rapidly changing geographies of global cyberspace. This paper explores the multiple geographies of the Arab Internet. First, it addresses Internet penetration rates, which averaged 7.8 per cent in 2006, although these varied widely among and within the region's countries. Between 2000 and 2006, the number of users jumped by 830 per cent, indicating these geographies are in rapid flux. It then examines the telecommunications infrastructure of the Middle East and North Africa, including fixed and mobile telephone networks and Internet cafes. Third, it turns to the reasons why the Internet has experienced relatively late adoption among Arab countries, including the dominance of the Latin alphabet, high access costs reflecting state-owned telecommunications monopolies, low Arab literacy rates, and restrictive gender relations that keep the proportion of female users low. The paper pays special attention both to government censorship of the Arab Internet as well as resistance to such controls and attempts to utilize the Internet counter-hegemonically. Finally, it explores the impacts of the Internet on some Arab societies, including the opening of discursive communities of politics, the Palestinian–Israeli conflict, Iraq and electronic commerce. 相似文献

Summary Internet websites provide a new are na in which companies can create images and representations with attendant geographical narratives. A case study of the websites of the 20 largest US-headquartered food, beverage and food service companies reveals an extensive use of geographical narratives that play on the particular spatial dimensions of the internet. The websites of many of these companies attempt to project and situate corporate activities within a stylized representation of the local and the global, thus providing a 'space' for corporate discourse within cyberspace. Insights gained from this case study highlight the importance of geography and geographical metaphors within the discursive lives of companies. The paper concludes that corporate websites portray idealized identities within idealized geographies. 相似文献

A common problem faced by geography departments, particularly during times of fiscal compression and mounting pressure for accountability, is how to compare themselves and their faculty with others. The recent revolution in bibliometrics provides a growing volume of data that can be used in benchmarking exercises. In this article, we assess the production and citation of journal articles and books by tenure-track and tenured faculty in selected U.S. and Canadian geography departments (n = 17) according to a set of readily derived and transparent performance indicators derived from publicly available data. Scopus was used to assess article production and citation; Google Scholar was used for book citation. Results point to significant heterogeneity in department characteristics, productivity, and citation of published work. The number of publications, citations, and h-Index scores among scholars in the sample (n = 369) is related strongly to academic age and subfield of enquiry (i.e., physical or human geography) but not—despite apparently marked differences in output and citations—to gender. 相似文献

"Using the household-level data provided by the 5% PUMS [Public Use Microdata Sample] data from the 1990 Census, this paper reports the pattern of ethnic mixing at the household level in the U.S. and also describes the geographical patterns of different types of multiethnic households at both the state level and the PUMA [Public Use Microdata Area] level. Several of the largest metropolitan areas are also examined in greater detail. The strong dominance of whites in the process of ethnic mixing is clear, as is the expected dominance of blacks in southeastern U.S. and the dominance of Hispanics in the southwest at the state level. The PUMA-level analysis reveals local clusters of ethnic mixing that are not apparent at the state-level analysis." 相似文献

This paper reviews the state of higher education human geography in contemporary Malaysia in relation to four main challenges: defending the unity of identity of higher education geography as a coherent and distinct discipline; ensuring the institutional survival of geography in higher education; enhancing the visibility of geographers as public intellectuals; and fostering the internationalization of human geography in Malaysia. It also suggests possible measures in responding to these. Moreover, while sharing the problems of developing higher education human geography experienced in other countries, Malaysia suffers most from national education policies that place lesser importance on the teaching of geography in schools, that stipulate a non‐English (Malay) medium of instruction, and that have been late in espousing an outward looking research university concept. In summing up the prevailing conditions as depicting a mixed bag of benign contentment, hard‐nosed pragmatism and continuing frustrations, it is uncertain whether recent policy changes to advance research environments in public universities can appreciably alleviate the fourfold challenges mentioned above. 相似文献

Gottmann in his classic Megalopolis attributes the dominance of the Northeast to its function as the hinge region of the United States. In this paper, we show, via statistics on maritime trade and interregional freight traffic by rail, that Megalopolis is no longer the dominant “hinge” region. We present evidence that the Gulf region may be supplanting it in this function. Finally, we speculate on some of the reasons for the Gulf's rather sudden assumption of this role and its implications for the economic geography of the U.S. 相似文献
