Analyses of criminals' travel patterns can provide significant suggestions to improve crime management. This study extends the investigation of criminals' travel behavior from journey‐to‐crime to journey‐after‐crime. Moreover, new methods are developed to examine the spatial patterns of location pairs when restricted by the underlying geographical process. The methods are employed to investigate criminals' journey‐after‐auto‐theft in the city of Buffalo, New York. The analyses reveal that auto thieves' trips from vehicle‐theft locations to the corresponding vehicle‐recovery locations are local in nature. The travel distances are significantly shorter than the randomly simulated trips; the travel directions are biased from the random directions as well.  相似文献

Ethno‐territoriality is an increasingly invoked term by those doing research on nationalism and ethnic conflict. Despite this, it has not been subject to detailed definitional and conceptual examination. This article develops a conceptual framework for thinking about ethno‐territoriality and ethnic conflict. It begins by briefly describing the relationship between territoriality, state sovereignty, and nationalist politics. I then provide a definition of ethno‐territoriality and outline a four‐part typology of the key elements of ethno‐territorial practice. Following this I discuss the role that ethno‐territoriality plays in the making of ethnic conflict.  相似文献

在开封自南宋以来的变迁历程中,因中原地区地理空间区位形势所造成的频繁战患直接导致开封城市的破坏与衰落,更重要的是开封在黄河泛滥区中所处的地理中心位置,不仅使开封周边地区土壤严重沙化,而且还在堰塞其水运河道的同时,也使其失去了成为现代铁路交通枢纽的机会。区域环境因素发生的重要改变导致中原地区区域政治中心在建国初从开封迁离,而改革开放以后随着经济自由流动程度的加强,更多的发展资源向邻近的郑州集聚,也造成开封经济发展的弱势。但随着国家及河南省政府利用开封地理空间区位形势所实施的"郑汴一体化"等当代发展策略的介入,开封将改变长期以来形成的下降趋势而实现复兴与发展。  相似文献

Location‐based social media (LBSM), a specific type of volunteered geographic information (VGI), is increasingly being used as a spatial data source for researchers in geography and related disciplines. Many questions, though, have been raised about VGI data in terms of its quality and its contributors. While a number of studies have explored users’ demographics and motivations for contribution to explicitly geographic forms of VGI, such as OpenStreetMap and Wikimapia, few have focused on these aspects with implicitly geographic forms of VGI, such as LBSM (for example, Twitter and Instagram). This study, through use of an online survey, specifically assesses the LBSM behavior and perceptions of 253 university students, noting differences found in gender, race, and academic standing. We find that the greatest differences are those between males and females, rather than through race or academic standing, and LBSM appears less biased than other forms of VGI.  相似文献

ABSTRACT. This article examines the geographical ideology of al‐Qa'ida. The central questions are to what extent al‐Qa'ida terrorism is motivated by a desire to control geographical space, and how the organization defines that space as place in its communiqués. The study also asks whether al‐Qa'ida's geographical rhetoric reveals the nature or locations of future attacks. Principal sources are statements and interviews by and with al‐Qa'ida leaders. al‐Qa'ida classifies distinctive geographical realms of legitimization, preparation, and action. Its geographical concerns and ambitions are hierarchical and based principally on perceptions of sacred space. The holy places of Mecca, Medina, and Jerusalem are the cornerstones of a greater Islamic holy land that al‐Qa'ida seeks to rid of non‐Islamic‐especially U.S. and “Zionist”‐elements and replace with a new caliphate. Terrorism directed principally against American civilians in the United States is one of the main tactics by which al‐Qa'ida says it hopes to achieve its goals in geographical space.  相似文献

ABSTRACT. The house‐lot garden in central Mexico is gendered space where changing cultural identities are negotiated, re‐created, and celebrated as “tradition” is continually redefined. No clear boundary separates the kitchen from the house‐lot garden or the private space of the household from the semipublic space of the community. During collective food preparation for religious fiestas, gendered reciprocity networks strengthen community relations and foster alliances between traditional neighborhoods and between communities in the region. At the intersection of everyday life and fiestas, food‐preparation spaces, or kitchenspaces, in the house‐lot garden are fertile areas in which to explore the cultural reproduction of nature‐society relations. They are vital to understanding gender, place, and culture in this region and represent people's symbolic connection with the land in increasingly urban contexts. This article analyzes the sense of place that Mexican women derive from their house‐lot gardens.  相似文献

This paper focuses on Hong Kong's Gravesweeping Festivals, Qingming and Chongyang. The practices carried out in urban cemeteries at these Festivals are over two thousand years old, and represent “time out” from modern “clock time”. They are examined in the context of Giddens' (1985) reworking of Hägerstrand's time‐space geography, and of Douglas' (1966) discussion of pollution. It is suggested that the cemeteries are regarded as dangerous places because they represent liminal spaces. Giddens' dimension of span enables a distinction to be made between, on the one hand, the long‐established cultural significance of the grave, and, on the other, the recentness of the urban cemetery. The dimension of form(redefined from Giddens' original concept), applied to some details of cemetery landscapes, reveals the “worlds apart” of the non‐material worlds of the spirits and of fengshui. By considering the Festivals in the light of Giddens' dimension, character, it emerges that the Gravesweeping Festivals are, as they have been for centuries, firmly embedded in Hong Kong's social system, where routines of ancestor veneration continue to renew and strengthen the family bonds that are at the heart of Confucian values. Furthermore, their continued observation may well represent practices that are of deep ontological significance to the predominantly immigrant community of Hong Kong.  相似文献

The timing of clastic sedimentation in two glacial‐fed lakes with contrasting watersheds was monitored using sequencing sediment traps for two consecutive years at Allison Lake (Chugach Range, Alaska) and four months at Shainin Lake (Brooks Range, Alaska). Shainin Lake is a weakly stratified lake fed by distant glaciers, whereas Allison Lake is more strongly stratified and fed predominantly by proximal glaciers. At Shainin Lake, sediment accumulation started in late June and reached its maximum in mid‐August, just before lake mixing and during a period of low river discharge. The grain size of the sediment reaching the sediment trap in Shainin Lake was homogenous throughout the summer. At Allison Lake, pulsed sedimentation of coarse particles during late summer and early fall storms were superimposed on the fine‐grained sedimentation pattern similar to that observed at Shainin Lake. These storms triggered underflows that were observed in the thermal structure of the lake and deposited abundant sediment. The sequencing sediment traps reveal a lag between fluvial discharge and sediment deposition at both lakes, implying limitations to interpreting intra‐annual sedimentary features in terms of inflow discharge.  相似文献

I use a gender framework to examine why women need to utilize social networks to discover and resolve problems related to reproductive tract infections (RTI) and sexually transmitted diseases (STDs). In India, women's health is linked with social status and perception of their health needs. This paper provides insight on how social networks are gender‐, location‐, and context‐specific and how they are linked to STD issues. This paper examines why social networks are integral to women. The health‐seeking behavior of rural and urban casual sex workers is examined via Q‐analysis, a language of mapping relationships. Results from Q‐analysis reveal women's use of four systems—kinship, belief, traditional medical, and western medical services. Finally, I conclude with important implications for research on gender relations and social networks.  相似文献
