地理学家的演讲与他们运用文字、图象所作的交流同样值得重视.美国的地理学可以通过下述途径得到加强,即围绕地点、地区和全球联系发展实质性演讲,促进自然地理的发展,恢复地理生态的传统.地理信息系统(geographic information systems)对于完成上述任务,对于改进地理学科以满足不断出现的需要,将是一个非常有用的工具.如果我们能够避免自己拆自己的台,避免不现实的空想,避免玩弄语言技巧,而是坚持在大学里进行高质量的教学,并在教师和从事地理实践工作的人员之间开展学术交流,那么地理学将会变得更加有效.我们有一个前所未有的机会来帮助改进美国的中小学地理教育.  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

The Early Bronze Age was a time of major changes in southern Levantine regions. The spread of urbanisation in the course of the third millennium BC was accompanied by various socio-political transformations, tensions and also violent encounters, even if the evidence for the latter is hard to detect in the archaeological record. The almost complete absence of arrowheads from settlements and tombs in the southern Levant from this period has led to the assumption that combat archery was not employed during the Early Bronze Age.

This paper challenges this orthodoxy using evidence from the southern Levant and beyond, and it concludes that archery was employed in combat activities during the Early Bronze Age, albeit on a small scale that was determined by military considerations.  相似文献

In debates over post‐capitalist politics, growing attention has been paid to the solidarity economy (SE), a framework that draws together diverse practices ranging from co‐ops to community gardens. Despite proponents’ commitment to inclusion, racial and class divides suffuse the SE movement. Using qualitative fieldwork and an original SE dataset, this article examines the geospatial composition of the SE within the segregated geography of Philadelphia. We find that though the SE as a whole is widely distributed across the city, it is, with the exception of community gardens, largely absent from poor neighborhoods of color. We also identify SE clusters in racially and economically diverse border areas rather than in predominantly affluent White neighborhoods. Such findings complicate claims about the SE's emancipatory potential and underscore the need for its realignment towards people of color and the poor. We conclude with examples of how the SE might more fully address racial injustice.  相似文献

This paper examines settlement density and settlement patterns in the Roman colonial territories of Venusia, Cosa and Aesernia, located in three different landscapes of central southern Italy (modern Basilicata, Tuscany and Molise). Using a series of GIS tools, we conducted a comparative analysis of the density and spatial distribution of sites dating to the Hellenistic period (ca. 350–50 b.c.). We used the legacy settlement data collected by previous large-scale, intensive, site-oriented field surveys to test the validity of two competing rural settlement models of early Roman colonization: the conventional model of neatly organized settlements regularly dispersed across the landscape and the recently proposed theory that colonists adopted a polynuclear settlement strategy. After calculating the extent to which the archaeological datasets conform to the regular or polynuclear model, we conclude that only a very small portion of the colonized areas actually meets traditional expectations regarding the organization of early colonial settlements. Our analyses show that the legacy survey data is more consistent with the polynuclear settlement theory, but the data also reveals some completely unexpected patterns, suggesting that early Roman colonial landscapes were more diverse than previously thought.  相似文献

Teaching of critical spatial thinking in higher education empowers graduates to effectively engage with spatial data. Geographic information systems (GIS) and science are taught to undergraduates across many disciplines; we evaluate how this contributes to critical spatial thinking. The discipline of GIS covers the whole process of spatial decision-making, but GIS modules often ignore the context setting of spatial problems, and just cover the technical aspects of how to use GIS software. We outline how some existing GIS practicals could be improved to focus on the development of critical spatial thinking skills, competences and abilities that are valuable to graduates.  相似文献

The benefits of urban open spaces for improving the quality of life and sustainability in cities are widely recognized. The functions they perform within the framework established by urban planning, as well as their metrics, are now more complex than in the past. It is convenient to develop methodologies for the evaluation of these spaces adapted to the present time to check their level of efficiency, which is useful in urban planning for the establishment of new urban open spaces. The aim of this study is to classify such spaces through a methodology that integrates spatial analysis, configuration analysis, and decision support so as to understand their complexity from a more advanced analytical perspective. In order to do this, a prior exploration of specific literature is carried out, which allows the characterization of the functions of urban open spaces by means of the corresponding analysis variables in a weighted manner. The integrated combination of these advanced tools is a step forward in achieving consistent and detailed results for urban open spaces. They perform their functions best in dense, central, equipped, accessible, connected, and easily walkable urban environments. In addition, future recommendations are provided.  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

Lee, D.-C. February 2017. Radialimbricatus, a new ichnogenus from the lacustrine sandstone facies of the Lower Cretaceous Jinju Formation, South Korea. Alcheringa XX, XXX–XXX.

The trace fossil Radialimbricatus igen. nov. with type species of R. bitoensis isp. nov. occurs in river-mouth-bar sandstone beds of a lacustrine sequence of the Lower Cretaceous Jinju Formation in South Korea. Radialimbricatus is a horseshoe-shaped or elliptical, convex hyporelief structure characterized by imbrication of traces with radial ridges and a median furrow. These features differentiate Radialimbricatus from arthropod ichnofossils such as Rusophycus and Cruziana, possibly cnidarian ichnofossils such as Astropolichnus and vermiform organism ichnofossils such as Oldhamia. Cross-sectional features of R. bitoensis, including upward mud protrusions at lateral margins, demonstrate that R. bitoensis can be formed as an open epigenic furrow at the water/mud interface or an endogenic burrow along the sand/mud interface at the same time. Analysis of discrete and imbricating horseshoe-shaped traces indicates that the tracemaker maintained an obligate inclined posture even when forming trails. The radial ridges and pit along the median furrow are interpreted to reflect feeding behaviour, and the imbrication to result from unidirectional and more or less regular movements to next feeding sites. The tracemaker is thought to have been an organism with an elliptical body outline, radially arranged body parts at the base of or around the body (probably for collecting and transporting foods and moving to feeding sites) and a mouth near the centre of the body, which is consistent with body plan features of arthropods, cnidarians and annelids.
