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

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

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

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

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

Public participation geographic information systems (PPGIS) increasingly are utilized in geographic research, yet researchers rarely are provided with guidance on how to implement PPGIS in an appropriate and effective manner. This article reports on the process of research that explores responses to current and future local tourism development offered by a sample of residents using a modified PPGIS approach called ‘community action geographic information system’ (CAGIS). The conceptual development of CAGIS is reported and the challenges encountered during its implementation in Churchill, Manitoba during 2005–2007 are reviewed. It is suggested that researchers wishing to conduct similar research should undertake thorough preliminary fieldwork to assess the likelihood of finding agreement on a common problem; acquiring adequate resources; establishing collective responsibility for the project's outcome; attaining stakeholder support; developing trust and meaningful relationships; and incorporating indigenous knowledge appropriately. Feedback of results to community members also should be an integral part of the research process. A number of feedback mechanisms are reported, including an interactive weblog, which helped facilitate communication between heterogeneous groups in Churchill. Although ambitions for a truly participatory GIS approach to this project have been set aside, it is held that PPGIS can yield positive outcomes for communities and academia. Sharing this research experience will be useful to others who venture into PPGIS research, especially in northern communities. 相似文献

This article examines the location of functions within the electricity sector in Canada from 1971 to 2001, using a centre‐periphery model. Power generation, distribution and retailing are generally carried out by multiestablishment crown corporations. Location patterns of different functions—management, scientific, production, etc.—are analyzed via the use of occupational groups. The spatial distribution of functions is found to be generally consistent with centre‐periphery relationships, with evidence of a growing functional specialization between large metropolitan and nonmetropolitan locations. However, differences emerge depending on power generation sources: fossil fuels, hydro, nuclear, solar or biomass. The choice of a power generation source has consequences for local economies. 相似文献

China has experienced considerable economic growth following the economic reforms of 1978, while simultaneously facing dramatic increases in regional inequality. China is becoming a polarized society—a phenomenon that is at the heart of a multitude of serious problems that are threatening sustainable development, as well as social cohesion within the country. Among the key reasons for this polarization are the quality of and accessibility to basic education for children. Since the establishment of the law for nine‐year compulsory education in 1986, children's education has progressed remarkably in most parts of China. It has, however, remained persistently problematic in the western provinces, particularly in remote regions, rural areas and minority communities. Even though some studies on child education in China have been carried out, very little existing research examines spatial inequality in children's schooling or accounts for the importance of sociocultural and geographic contexts. Using the example of Gansu, one of the poorest provinces in Western China, our research emphasizes the two main aspects that have led to high nonschooling rates for children: an unfavourable sociocultural milieu and inadequate educational resources. 相似文献
