A missing link? Network analysis as an empirical approach for critical physical geography

Critical physical geography (CPG) calls for integrative research on material landscapes and the socio-political dynamics of scientific knowledge production. Network analysis, a rich tradition of tools and approaches for analyzing relational information, has seen little use in the CPG literature to date. This represents a fruitful opportunity, as many of CPG's core interests—knowledge politics, histories of scientific concepts, and ecosocial relations—can be effectively analyzed using network techniques. In this article, I argue for adapting network approaches to CPG. First, I provide an overview of various network concepts, approaches, and their origins. I then discuss bibliometric network techniques for “science mapping” including co-word, co-authorship, and citation analyses. Next, I describe discourse network analysis, a recent mixed-method approach from political science. Finally, I discuss overlaps with emerging approaches from qualitative and visual network analysis. In each section, I provide existing and hypothetical examples, as well as software and visualization techniques, that demonstrate how network approaches could add new insights to CPG and related scholarship. Linking CPG with the diverse traditions of network analysis has the potential to produce new empirical understandings and bring the field into conversation with a growing body of research that spans the social sciences, natural sciences, and humanities.     

边疆地理名称与晚清川藏边务——以“川边”、“西康”概念为考察中心

晚清是近代中国边疆政治地理发生巨大变动的转折时期。随着边疆危机日趋深重,晚清时人逐步意识到慎重命名地理名称的重要性。川藏交界区域地理名称的生成、运用,经历了"炉边"、"川疆"、"川边"等名称混用,以"川边"为过渡性名称,到弃用"川边"、强调"西康"名称的过程。地理名称的变更与晚清川藏边务密切相关,特别是对"边"、"藏"界域之争的有力回应。探讨边疆地理名称多歧性、竞争性,则是本文将历史地理学研究与概念史方法相结合的一种尝试。     

An analysis of spatial patterns of toponyms in Guangdong,China

The unique geographical environment and the historical waves of immigration of the northern Han Chinese to the Lingnan region have contributed to the development of a complex and unique culture in Guangdong Province. Four ancient ethnic groups, the Zhuang, Cantonese, Hoklo and Hakka, have resided in this area for centuries. As an important part of local culture, toponyms often survive changes in history and can reveal the temporal differences between the past and present in landforms and the spatial differences in the distribution of different ethnic group populations. In this study, two goals were sought: (1) the adoption of spatial smoothing and interpolation methods to reveal the spatial patterns of the Zhuang, Cantonese, Hoklo and Hakka toponyms based on comparisons among the proportions of those who speak various languages and (2) the investigation of the differences among toponymic layers under regional environmental conditions and the influences of geographic factors using an independent samples t-test and a binary logistic regression.     

明清时期广东五邑地区政区变迁研究

广东五邑地区以潭江流域为中心,是一个相对独立的地理单元,但该地的政区边界却打破了自然山川的界限。从明代到清初顺治年间,为了应对以民变为首的地方政治危机,朝廷先后在潭江流域设置了恩平、新宁、开平三县。这些县级政区的边界大致与潭江流域的地理分界线重合,地理单元的独立性开始作用于政区划界中。清代雍乾年间,形成了新会、鹤山、新宁、开平、恩平五县分治潭江流域的格局。同时,随着新会县核心政区地位的巩固,流域内各县整合为一个统县政区的倾向开始加强,为后世潭江流域的政区整合奠定基础。明清时期潭江流域的政区变迁体现了地理环境和地方政治局势在政区格局形成过程中的根本性作用。     

What is Geography? Perceptions of first year undergraduates in South Africa

Disciplines such as Geography are well placed to respond to the changing needs of society and the effective application of geographical knowledge to real-world problems. This project surveyed first year Geography undergraduates’ understanding of “What is Geography?”, both before and after an exercise in which geographic topics were identified within recent newspapers. The survey instrument employed was an anonymous, self-administered questionnaire, and was undertaken with first-year undergraduate Geography students at a university in South Africa. Results show that the exercise enabled students (n = 158) to more readily see the application of geographical knowledge to both environmental and social problems that they identified in the newspaper stories. Students also identified that studying Geography may be able to help them increase their skills, employment prospects and earning potential. These findings can help locate the disciplinary concerns and applicability of Geography in post-apartheid South Africa within the wider context of the twenty-first Century world.     

Women following fish in a more-than-human world

Drawing on ethnographic and interview research conducted in Scotland, South Australia and New South Wales, Australia, I attempt to frame the cultural, social and geographical networks created by the people who follow fish (primarily commercial fishers). My account is constructed through a ‘self-conscious storying’ (Whatmore 2008) deployed by geographers working in a more-than-human perspective. Although I find much to inspire from this approach, throughout this article the question that nags at me is how to account for women within a materialist more-than-human framework, and how to articulate a feminist politics within this epistemological and methodological space. I try to avoid admonitions about what should be done and to advance or to model an embodied glimpse of what such a politics might be.

旅游生态足迹初探——以嵩山景区2005年"五一"黄金周为例

在生态足迹理论与方法的基础上,提出了旅游生态足迹的概念,运用旅游生态足迹计算模型,从旅游交通、旅游住宿、旅游餐饮和旅游购物等4个方面计算了2005年“五一”黄金周期间嵩山景区的旅游生态足迹,并与郑州市的生态足迹对比。结果表明:黄金周期间,嵩山景区游客的人均旅游生态足迹0.02264gha,是郑州市周人均生态足迹0.00436gha的5.19倍,旅游是一种对自然资源高需求、高消耗的生活方式。指出旅游生态足迹计算方法的特点,影响旅游生态足迹大小的关键因子,减少旅游生态足迹的途径和旅游生态足迹计算中存在的问题。     

Application of Landsat satellite imagery to monitor land‐cover changes at the Athabasca Oil Sands,Alberta, Canada

A major advantage of satellite remote sensing is that the imagery acquired provides a synoptic view of the landscape. Thus, repeat coverage by the satellite on a regular basis permits the detection of changes in land‐cover over time. This study demonstrates the application of remote sensing technology to the monitoring of mining activities at the Athabasca Oil Sands region of Alberta, Canada. First, we describe the techniques used to match a time sequence of Landsat imagery, both spatially and spectrally, to ensure that the spectral changes through time are due to land‐cover variations. A series of spectral trajectories were then extracted to assess changes in land‐cover through time. Secondly, a land‐cover classification was produced from the baseline 1984 imagery and, using historic and future mine extents, the classification was analyzed to determine the proportion of each land‐cover type affected through development. Results of the analysis indicate that since 1984 there has been a larger reduction in mixedwood dense and broadleaf vegetation classes than mixedwood sparse or dense conifer stands in the area. Based on the delineations of mine‐site activity, the area of woodland and wetland habitat subject to development has increased from approximately 2,520 hectare (ha) in 1984 to 32,930 ha in 2005.     

明清时期汉水下游地区的地理环境与堤防管理制度

明清时期国家对于汉水下游的水利管理制度经历一个变迁的过程,与这一区域的水利问题的日益突出密切相关,垸田的发展以及带来的问题是主要的因素。钟祥至沙洋的汉江干堤极易溃决,并且关系到整个下游地区的安全,因此在人力组织、资金筹集、岁修维护上,国家的政策表现出明显的倾斜性,相对于沙洋以下的区域,给予了充分的重视。沙洋以下,天门、潜江、沔阳等州县所在区域主要以垸田为主,国家将这一区域的堤防修筑与维护主要交由地方来进行。垸堤岁修维护采取堤甲制的组织形式,由垸民完成,一方面没有固定的资金,另一方面在正常年景之下,垸民可以获得基本的物质生存,因此垸堤的维护面临相当的困难。
