Although the spatial structure of employment in large US metropolitan regions is a well-researched topic, few studies focus on medium-sized and small US metropolitan regions. Consequently, there is no overall typology relating small-to-medium urban form to employment distribution. We address this gap by investigating the spatial structure of employment in 356 metropolitan regions. We conceptualize six typologies based on three categories that have overlapping properties: “monocentricity,” “polycentricity,” and “generalized dispersion.” The study has three main findings. First, the three types of urban form that we identify as “hybrid” outnumber the three “pure” types by almost four to one. Second, job dispersion is a dominant characteristic in almost 70% of all metropolitan statistical areas (MSAs) (including the hybrid types), and polycentricity (56.7% of MSAs) is somewhat more common than monocentricity. Third, there is a strong relationship between population size and density. The population of medium-sized metropolitan areas is generally more dispersed than that of small and large metropolitan areas. Polycentricy emerges mostly in large metropolitan regions, while monocentrity is found in both small and large metropolitan regions.  相似文献

MAINTAINING AUTHENTICITY AND INTEGRITY AT CULTURAL WORLD HERITAGE SITES   总被引:1,自引:0,他引:1  
To be considered for listing as a World Heritage site, properties must meet the conditions of “integrity” and/or “authenticity” and be of “outstanding universal value.” Identifying and maintaining authenticity and integrity at cultural heritage sites are challenging goals, however. The concepts are difficult to define and are open to different interpretations in different cultural settings. Additionally, the diversity of sites and wide variety of influences on them require individualized approaches to preservation in many cases. Nonetheless, authenticity and integrity are useful guiding concepts in striving for a systematic approach to preservation in diverse contexts. In this article we discuss preservation approaches that are appropriate at a range of sites, paying particular attention to the tensions that arise when balancing the need to maintain authenticity and integrity with the needs of the people who live in or visit these sites.  相似文献

This study aims to characterize urban spatial structure with respect to its multidimensionality. Using an encompassing data set of socioeconomic variables, as well as variables pertaining to the built environment, accessibility and land use, we suggest a quantitatively based urban (sub-) center typology. The fine-grained spatial scale of 1 km2 grid cells permits a higher spatial resolution than that used in most previous studies. Our suggested typology is two-layered: a “macro layer” based on cluster analyses sheds light on urban spatial configurations. A corresponding threshold-based “micro layer” identifies distinctive types of centers and subcenters at the local level. The application of this multi-scale and multivariate typology to four German city regions indicates both the core cities’ morphological dominance and the formation of subcenters with distinct profiles of regional economic importance, land use patterns and urban form. However, a substantial degree of spatial dispersion is observed because much activity is located in non-central locations.  相似文献

Understanding the Changing Planet: Strategic Directions for the Geographical Sciences(UCP),published by the National Research Council(USA),and its comments in The Professional Geographer propose that uppercase and plural "Geographical Sciences"(GS) is the strategic direction for geography in the next decade for better understanding of our rapidly changing planet. According to these comments,UCP valued technologies and tools excessively("task"),and did not pay much attention to methodology("discipline"). Actually,both"task" and "discipline" are geographical wings,especially in the time of "big science".Enlightenment from UCP and its comments is the strategic direction that should be balanced between "task" and "discipline",GS should be a three-dimensional construct of a disciplinary system,methodology,and technologies and tools,and this system should be scientific humanism based on scientific spirit and directed by humanism. During the last 60 years,Chinese geographers devoted themselves to GS,including practice and theory. Obviously progress and outlook are proposed as interdisciplinary GS,Earth Surface Sciences(ESS) and Geographical Construction(GC). The disciplinary system of GS is very complex,and is composed of such human knowledge domains as sciences,technologies,engineering,and philosophy. The main mission is to research the open,complex,and macro earth system(not only scientifically,but also humanistically),and one significant methodology is "comprehensive integration of qualitative and quantitative means"(CIQQM). At the same time,another changing direction in Chinese geography is Human-Economic Geography(HEG).  相似文献

Despite widespread media coverage of livestock-related issues and growing scientific evidence linking meat production and climate change, systematic content analysis of this relationship in media coverage has been surprisingly minimal. In this article, we combine actor-network theory with framing theory to develop the basis for “story-networks”—networks of actants and artifacts that shape how a media report or “story” is framed. We coded livestock-related articles from a major U.S. newspaper, the Los Angeles Times, over the 1999–2010 period to understand how various actants and artifacts shaped different story-networks. Just 5% of all livestock articles addressed connections with climate change; these articles focused on technology, lifestyle, or policy. Distinctive story-networks characterized each category, framing the livestock–climate change linkage as an issue to be addressed through either technological innovation, individual lifestyle choices, or policy action. In each story-network type, varying configurations of actants and artifacts were involved, including the cattle themselves.  相似文献

With the socio-economic development associated with urbanization, the urban-rural relationship has changed across the world. In China, due to the urban-rural dual structure, these changes turn out to be more complicated. Spatial restructuring are suggested as the main strategies and spatial supporting platforms for urban-rural development. However, the theory still lacks solid methodology and support from systematic empirical studies. This study seeks an adequate scientific methodology and discusses the difference of urban-rural transformation in plains and mountainous areas. A case in Shanghang County, China, demonstrates: 1) The compound ecological niche model can be a suitable approach in urban-rural restructuring, especially in mountainous areas. 2) The urban-rural development area with highly inappropriate, slightly appropriate, moderately appropriate, and highly appropriate areas are 1273.2 km2 (44.69%); 906.1 km2 (31.80%); 509.4 km2 (17.88%); and 160.1 km2 (5.62%), respectively. 3) The “deserting villages” in mountainous areas play positive synergistic roles in urbanization, in contrast to the “hollowing villages” common in plain areas. 4) The central town-village will become the most important settlement in mountainous areas. Therefore, we suggest more attention should be paid to environmental capacity in the construction of central town-villages. This study significantly extends the understanding of “hollowing village” theory and regional planning.  相似文献

ABSTRACT. In order to view the establishment of new religions centers and how they are received by local populations, I analyze such basic geographical concepts as scale, space, location, and image. I see how these can alter the perception and further refine the concept of spatial transgression in three case studies in Israel: the building of the Mormon Center in Jerusalem, the establishment of the Bahá‘í Gardens in Haifa, and the struggle to build a mosque in Nazareth. In this article I seek to identify the factors influencing the presence or absence of conflict to help explain the different “stories” revealed. The article also constitutes an addition to the literature on Israeli (and Palestinian) religiogeographical controversies by focusing on nonmainstream or nondominant cases and by comparing the relative roles of different factors that shape the success or failure of spatial transgressions in religious geography.  相似文献

Recent urban transformations in China have led to critical reflections on the low-quality urban expansion in the previous decades and called for the making of vital and lively urban places. To date, limited research has been devoted to empirically testing the relationship between urban design, urban morphology, and urban vitality in Chinese cities. This paper employs new urban data and analytical methods and explores the relationship between urban morphology and urban vitality using regression models. Shenzhen, one of the largest and fastest growing cities in China, is selected as the case study. The regression analysis focuses on two morphological factors, density and typology, while controlling for the accessibility, functional mix, and size of individual blocks. The presence of small catering businesses is used as a proxy for urban vitality. The analysis suggests that both typology and density matter for urban vitality, with typology playing a more important role. More specifically, “block” and “strip” types tend to show significant positive effects on urban vitality. The implications for urban planning and design practices are discussed.  相似文献

Central Eurasia underwent significant palaeoclimatic and palaeogeographic transformations during the middle to late Miocene. The open marine ecosystems of the Langhian and Serravallian seas progressively collapsed and were replaced in the Tortonian by large endorheic lakes. These lakes experienced major fluctuations in water level, directly reflecting the palaeoclimatic conditions of the region. An extreme lowstand of the Eastern Paratethys lake (?300 m) during the regional Khersonian stage reveals a period of intensely dry conditions in Central Eurasia causing a fragmentation of the Paratethys region. This period of “Great Drying” ended by a climate change towards more humid conditions at the base of the Maeotian stage, resulting in a large transgressive event that reconnected most of the Paratethyan basins. The absence of a robust time frame for the Khersonian–Maeotian interval hampers a direct correlation with the global records and complicates a thorough understanding of the underlying mechanisms. Here we present a new chronostratigraphic framework for the Khersonian and Maeotian deposits of the Dacian Basin of Romania, based on integrated magneto‐biostratigraphic studies on long and continuous sedimentary successions. We show the dry climate conditions in the Khersonian start at 8.6–8.4 Ma. The Khersonian/Maeotian transition is dated at 7.65–7.5 Ma, several million years younger than previous estimates. The Maeotian transgression occurs later (7.5–7.4 Ma) in more marginal and shallower basins, in agreement with the time transgressive character of the flooding. In addition, we date a sudden water level drop of the Eastern Paratethys lake, the Intra‐Maeotian Event (IME), at 6.9 Ma, and hypothesize that this corresponds to a reconnection phase with the Aegean basin of the Mediterranean. Finally, we discuss the potential mechanisms explaining the particularities of the Maeotian transgression and conclude that the low salinity and the seemingly “marine influxes” most likely correspond to episodes of intrabasinal mixing in a gradual and pulsating transgressive setting.  相似文献

Abstract

This comment aims to further develop James and Brown proposal of framing organic conversions as transformations, referring to “the three spheres of transformation” (practical, political, and personal). Particularly, I address the dynamic interactions between the three spheres during the transformational process, and challenge James and Brown’s emphasis on the political sphere. To this aim, I first make explicit the temporal logic underlying James and Brown’s analysis, which is consistent with other conceptualizations in literature, also giving importance to the political sphere. Then, I mention an alternative approach, highlighting the potentially initiating role of key individuals and farmers’ epiphanies in the transformational process. This makes a strong difference in the narratives that can be made around organic conversions, by shedding light on the personal sphere and the “co-arising” of the three spheres. This proposal raises both methodological and theoretical questions, which can be addressed by introducing insights from quantum theory.  相似文献

ABSTRACT. Transplanting pilgrimage traditions, or the process of remaking the collective self in sacred places, requires new sacred places as worthy destinations. As people migrate from the lands where sacred places developed to those where such places may become only a distant memory, many communities attempt to recover their pilgrimage tradition by co‐opting sacred sites of host communities, maintaining links to their homeland, or re‐creating sacred sites in the lands of resettlement through replication, (re)recognition, creating movable rituals, celebrating sites of sacred embodiment, and ritual historicizing. Examples taken primarily from Catholic and Hindu experiences in the Western Hemisphere illustrate this preliminary typology. Transplanting pilgrimage traditions may be viewed as anchoring our individual, existential quests to fleeting ships of “collective selfhood.”  相似文献

Relational Cities: Doha,Panama City,and Dubai as 21st Century EntrepÔts   总被引:1,自引:1,他引:0  
In a dynamic global economy, emergent configurations of capitalist production produce novel spatial assemblages and correspondingly unique geometries of power. The “global cities” literature frames these transformative processes in terms of hierarchical world urban systems, providing a clear theoretical path to understanding the local implications of global spatial restructuring. This article develops the concept of the “relational city” as a transnational urbanist approach to understanding a particular subset of cities that are emblematic of the spatial transformations manifest through advanced capitalism. Relational cities are those constituted through globally critical flows of capital, goods, and ideas, and whose economies are dedicated to intermediary services such as offshore banking, container- and bulk-shipping, and regional re-exportation. Similar to gateway cities and entrepôts, relational cities are found eccentrically at one end of a fan-shaped network, connecting the global economy with a regional economic matrix. Drawing upon Doha, Dubai, and Panama City as illustrative case studies, this article suggests a new way of understanding urban change in a global context while simultaneously moving beyond the recurrent focus on the top-tier financial world cities of the Global North.  相似文献

Day-labor hiring sites are common features of the contemporary North American landscape. These are public and semi-public spaces where mostly male residents congregate daily in hopes of being hired for short-term work. Research on contemporary day-labor markets in the United States to date tends to be policy-oriented, intended to reduce the injustices that are a common part of life as a day laborer. Unfortunately, very little is understood about the spatial organization of day-labor markets. Drawing on more than five years of mixed-methods research in the San Diego Metropolitan Area (SDMA), this paper takes two important steps toward a spatial understanding of day-labor hiring sites. First, it demonstrates that informal hiring sites are established in locations that maximize laborers’ chances of finding employment. Second, it establishes a geo-spatial typology of hiring sites for the SDMA that can be used to better tailor day-labor support efforts and policy to site-level context.  相似文献

In this article I examine connections between my past experiences on the academic job market and my research interests, particularly in regard to the notion of transgression. I offer my personal “story” of job seeking as a contribution to the dialogue concerning the relationships between personal lives and professional experiences, and as a case study of how considerations of merit can become clouded by personal and social discomfort with difference.  相似文献

The anthropological machine is the discursive framework, the dispositif that grounds “Western man” in a sense of civility, secured through a violent division within and between the human and nonhuman: not the after-effect of the civilizing act but its very foundation. This paper explores Agamben’s machine at multiple sites: in its expression in everyday lives of urban citizens, and its legitimation of capitalist urbanization on broader spatial and temporal scales, its “worlding” through planetary urbanization and normalization of climate change. Complicit in capitalist urbanization and climate change, the anthropological machine has acted as a “switch point” since the 1600s. It now frames an emergent response: triage as the inevitable sacrifice of some peoples and parts of the planet to preserve others. If the urban is to become the site of mondialization, confronting the apparent inevitability of triage we must think beyond the either-or of a people or a planet. Thought in relation to the urban, the anthropological machine offers a meeting ground between urban political economy and assemblage urbanism. It enables us to situate the Anthropocene and differentiate the urban. But it also exposes a deep divide between scholars reframing the human beyond “Western man”: between those for whom the more-than-human expresses the dreams of a biophilic city and those for whom the less-than-human is increasingly its living nightmare.  相似文献

“面向区域”的GIS控件的设计与使用   总被引:4,自引:0,他引:4  
陈正江 《地理研究》2003,22(2):227-236
本文提出了一个“面向区域”GIS控件的概念———即以特定的地理区域为对象,将基础地理信息连同有关的GIS功能操作融合为一个可重用的程序模块,以Microsoft的COM(即“组件对象模型”)技术为基础,组织为“GIS化”的ActiveX控件。这种GIS控件,将面向对象技术中的“对象”扩展到了整个特定的地理区域空间,其核心思想是不仅封装了GIS的数据模型,必要的功能操作,而且封装了所有的基础地理信息。由于省去了对空间数据的处理,因而这种GIS控件可被广大非GIS专业的信息系统开发者灵活、简便地用于各种管理信息系统、办公自动化系统和决策支持系统的GIS功能扩充,也可用于构建一般的地理信息系统,因而有利于GIS技术应用的普及。文章最后给出了有关陕西省的应用实例  相似文献

ABSTRACT. “Community” is a good warm word frequently invoked by citizens, social workers, and politicians. “Society,” by contrast, is more ambivalent, invoking something elitist and exclusive, as in the expression “high society.” The word “individual,” or “individualism,” often connoting selfishness and bracketed with society, is even more suspect in our time. I plead for a restoration of balance and esteem among the three terms as a necessary step toward acquiring a fuller understanding of the human condition and potential.  相似文献

This article explores various ways of how to challenge the “otherness” of Islam and Muslims when teaching geography of Islam. It suggests a critical project of “teaching against culture,” which challenges essentializing notions of Islam as a monolith, and rather demonstrates the complexity of Muslim geographies and “lived” Islam. Furthermore, it implies examining the various identity categories and binaries such as secular–religious and West–East that come about in the classroom itself in the secular academic context of an urban state university. As such, the article engages in questions of significance to a wider set of courses on social and cultural geographies, geography of religion, and postcolonial geographies  相似文献
