Over the past several decades, GISystems and GIScience have become established and valorized within the field of geography and geographic education. With the recent explosion in daily use of devices producing spatial data, such as smartphones, has come a renewed call to broaden the purview of Critical GIS beyond the desktop and towards these new systems of capitalist accumulation. In this viewpoint, we argue that any re‐examination of the role of Critical GIS must also consider the political economy of geography and geographic education in which GISystems are used for research and taught. We explicate three registers at which GISystems function within geography: that of the individual educator, that of the GIS user, and that of the military‐industrial complex in which GISystems were and are developed. 相似文献

This paper builds upon studies employing a syllabi-based methodology that suggest a tendency for critical geographic information science (GIS) courses to emphasize reading/discussion about GIS without actually doing GIS, and for traditional GIS instruction courses to emphasize the technical capacities of GIS software without incorporating critical theory in substantive ways. However, through ethnographic evidence we reveal that there is likely more innovative theory-practice transcending pedagogies being utilized than would necessarily show up in such a syllabi-based methodology. There are also very real and differentially manifest pragmatic, departmental, and institutional barriers in place to effectively incorporating critical social theory into courses that actually do GIS. We first catalogue these barriers as a means of ascertaining what can (and cannot) be done to overcome them through GIS pedagogic innovation. We then outline the (often-veiled) pedagogic strategies deployed by critical GIS scholars today to navigate and circumvent these barriers. 相似文献

GIScience and GISystems have been successful in tackling many geographical problems over the last 30 years. But technologies and associated theory can become limiting if they end up defining how we see the world and what we believe are worthy and tractable research problems. This paper explores some of the limitations currently impacting GISystems and GIScience from the perspective of technology and community, contrasting GIScience with other informatics communities and their practices. It explores several themes: (i) GIScience and the informatics revolution; (ii) the lack of a community‐owned innovation platform for GIScience research; (iii) the computational limitations imposed by desktop computing and the inability to scale up analysis; (iv) the continued failure to support the temporal dimension, and especially dynamic processes and models with feedbacks; (v) the challenge of embracing a wider and more heterogeneous view of geographical representation and analysis; and (vi) the urgent need to foster an active software development community to redress some of these shortcomings. A brief discussion then summarizes the issues and suggests that GIScience needs to work harder as a community to become more relevant to the broader geographic field and meet a bigger set of representation, analysis, and modelling needs. 相似文献

Under current dialectical conditions of globalization and increased demands for security, borders are no longer just symbols of sovereignty and national histories; they are evolving into new forms and as such are taking on new functions. Yet while borders continue to exist and are arguably more fluid and dynamic than ever before, despite the once robust but now contested rhetoric of “a world without borders,” this doesn't mean that borders prior to the current phase of globalization were relatively static and stable. What is constant is the fact that borders and borderlands are always in a state of becoming and in this context, we need to address the relationship that exists between borderland evolution and the changing forces of globalization. This paper considers the important role that time‐space plays in globalization and borderland theory and in doing so emphasizes that any such effort must recognize the importance of historical geographical context. My argument is developed with reference to the Canadian‐American borderlands and the relationship between Canada and the United States that developed during the various phases of globalization that emerged after the creation of two North American polities following the American Revolution. 相似文献

In the last decade, conversations around queering of GIScience emerged. Drawing on literature from feminist and queer critical GIS, with special attention to the under‐examined political economy of GIS, I suggest that the critical project of queering all of GIS, both GIScience and GISystems, requires not just recognition of the labour and lives of queers and research in geographies of sexualities. Based upon a queer feminist political economic critique and evidenced in my teaching critical GIS at two elite liberal arts colleges, I argue that the “status quo” between ESRI and geography as a field must be interrupted. Extending a critical GIS focus beyond data structures and data ethics, I argue that geographic researchers and instructors have a responsibility in queering our choice and production of software, algorithms, and code alike. I call this production and choice of democratic, accessible, and useful software by, for, and about the needs of its users, good enough software. 相似文献

GISystems have strong and longstanding roots in Geography, stemming from early developments in the 1960s and 1970s that defined a first phase of their relationship. But as the uses and sophistication of geospatial technology have grown and spread across virtually all areas of the academy, reducing Geography's claim to ownership, that relationship to Geography has evolved in new directions, forming a second phase. The critiques of the early 1990s have led to research into the societal context and social implications of GISystems that remains largely centred in Geography; techniques for the analysis of data embedded in space and time remain strongly associated with Geography; and rigorous principles have been discovered under the umbrella of GIScience that are widely recognized within and outside Geography. Today the relationship has entered a third phase, defined by the new opportunities that are being created by the growth of data science, by new sensors, and by new areas of application, suggesting that the relationship between Geography and GIScience will continue to evolve in interesting and exciting ways. 相似文献

Higher-education geographic information system (GIS) curricula largely marginalize and separate instruction of critical GIS and open GIS, paralleling a divide between GIS and non-GIS in geography. GIS is typically represented as a singular, infallibly objective, and universally applicable technology. GIS generally dismisses the critiques from human geography, while critical human geography dismisses GIS for its association with positivism and unethical applications. Teaching critical open GIS may bridge this divide, creating a transformative pedagogical space for human geography to affectively and effectively engage with open GIS technology at the level of code. Critical open GIS students practice and critique GIS as conflicted insiders, bridging the divide between GIS and non-GIS in their geography education. Reviews of GIS curricula find support for teaching critical and open GIS, but reviews of texts and syllabi confirm their marginalization and separation. A new critical open GIS course is introduced, using GIS in development and political ecology as integrative frameworks. 相似文献

In 2014, the Joint United Nations Programme on HIV/AIDS set the target of dramatically reducing the burden of HIV through expansion of access to timely HIV treatment. In order to achieve this target, it is necessary to expand access to care along the HIV cascade of care. This study examines the relationship between viral suppression and the availability of physicians providing HIV treatment in British Columbia, Canada. Data from the Drug Treatment Program of the British Columbia Centre for Excellence in HIV/AIDS was analyzed. The floating catchment method was used to assess physician availability and multivariable logistic regression was used to implement a confounder selection technique to independently assess the relationship between physician availability and viral load suppression. Individuals with more than 25 physicians within a one‐hour catchment were more likely to reside in urban areas and almost twice as likely to have a suppressed viral load (adjusted odds ratio: 1.97; 95% CI 1.50 – 2.58). This study highlights the impact of physicians’ availability on viral load levels. Mapping technology was used to identify the locations in which patients were most impacted by the lack of physicians. 相似文献

New technologies enable high‐resolution monitoring techniques and the generation of big data and have been heralded as increasing the depth of our understanding of geomorphic phenomena. These technologies, however, also provide us with a convenient entry point into the increasingly constraining political economy of geomorphology. Building on the work of Stuart Lane and of critical physical geographers, this paper traces and examines the multiple roles that new technologies have played in constraining research questions and directing resources. Using the activity sphere framework outlined by David Harvey, the influence of new technologies can be traced around the spheres and their constraining of existing relations within academia and explanation identified. 相似文献

Through a study of trade fairs, this article illustrates that relational approaches to economic geography are not limited to the sphere of economic and social relationships. These relationships are influenced by and, in turn, shape material realities, such as specific infrastructure and the labour market, in a reflexive manner. Trade fairs are “relational events” that bring together regional, national, and often international producers, users, suppliers, and other agents of a value chain or technology field for the purpose of exchanging knowledge about technological and market developments, building partnerships, and maintaining existing networks through learning by interaction and observation. However, these events are also situated in space and time, grounded in the contexts of particular industries, trade patterns, public and private investments, as well as the economic geographies of places. Focusing on North America, this article presents and analyzes data on the economic geography of trade fairs and their regional economic impact (number of events, exhibitors, attendees, exhibition space). It explores regional trade fair patterns and dynamic changes in major trade fair cities by emphasizing the role of history and industry context. 相似文献

Quiet urban areas are places with low noise levels that can help people to support physical and mental wellness. This paper has two objectives: to identify quiet urban areas in Montreal and to check for the presence of environmental inequities in access to such areas for vulnerable groups (children, older people, low‐income individuals, and visible minorities). Using a GIS‐based methodology, 2,282 quiet urban areas were identified in Montreal. The results of a mixed effects logistic regression model analysis showed that there are no major inequities in access to quiet urban areas for the population groups studied. The analysis did, however, revealed substantial spatial disparities in terms of the distribution of quiet urban areas across the boroughs and municipalities examined. 相似文献

Wetlands are common in Coastal Western Hemlock forests yet the hydrologic processes that generate runoff from small swamps are not completely understood. Direct field observations, hydrologic, and electrical conductivity data were collected from a gently sloping forested swamp complex from July to November 2009. Swamps occupied depressions between raised mounds (0.1 to 3 m high) and were connected by an ephemeral creek. Runoff was controlled by antecedent moisture conditions and influenced by basin microtopography. Two hydrologic regimes occurred during the study period and different runoff processes dominated each regime. Runoff was generated by subsurface flow during dry antecedent conditions as swamps remained hydrologically disconnected from each other. Runoff was generated by surface outflow from hydrologically connected swamps during wet antecedent conditions as ponded water spilled out of the depressions. The forested swamp complex produced a faster but limited hydrologic response during dry antecedent conditions compared to a slower but greater hydrologic response during wet antecedent conditions. Stormwater runoff and runoff ratios were up to two orders of magnitude higher in wet conditions than during similarly sized events in dry conditions. These factors should be considered when designing monitoring programs or runoff models in forested swamps with significant microtopography. Field surveys and estimates of hydrologic inputs and outputs may be useful in predicting the potential hydrologic connectivity of isolated forested swamps. 相似文献
