We present an analysis of the effects of different information flow patterns on the growth of spatial structure in a broad class of systems. Examples are drawn from plant and message diffusion processes, the growth of herding in animal populations and, in particular, the evolution of cities in human populations. We model the actions of an “individual” as a response to gradients in a transformation of the “real” space, this transformation being the individual's information map of the space. Interesting deductions occur as a result of allowing the individual's information map to vary from extremely local to extremely global. In the city growth model for example, if migration decisions are based upon extremely local information, then the system is characterized by instability and the lack of any well-defined spatial structure. As the localness of this information map decreases, the system is characterized by the development of well defined spatial structure with a characteristic distance separating the “cities.” In a particular case, we show that the wavelength of the dominant spatial structure is directly related to the size of an individual's information field. These effects are a consequence of interactions between individuals that arise from the nonlocalness of the information fields. We interpret the early growth stages in these models in terms of linear filters.  相似文献

Abstract

Spatial rescaling arguably represents one of the most significant recent changes in planning. Rescaling processes do not merely imply changes in powers across existing layers of decision-making, but also entail new scales of intervention, new actor constellations and new geometries of governance. A wide range of examples of spatial rescaling can be seen across Europe, varying from local through to regional and international. The emergence of “soft spaces”—regions in which strategy is made between or alongside formal institutions and processes—is one of the phenomena associated with contemporary spatial rescaling. These spaces are often overlapping and characterized by fuzzy geographical boundaries. The formation of soft spaces is often articulated in terms of breaking away from the rigidities associated with the practices and expectations of working within existing political or administrative boundaries but can also be viewed as providing a means of bypassing formal procedures and reducing democratic accountability. Focusing on European territorial cooperation and development strategies in the Baltic region, this paper discusses how they are contributing to spatial rescaling in soft spaces and how the strategies can be seen as a form of soft planning and as a means to promote soft security policy (which could be considered as a wider form of foreign policy).  相似文献

Abstract: This article mobilises a strategic‐relational approach to state spatial restructuring to overcome the weaknesses of the conventional “New Regionalist” account in economic geography of the resurgence of the region as a strategic site for economic governance. Focusing on hegemonic projects and the shifting nexus of spatial dependencies and engagements through which these are reproduced, undermined and transformed, the role and geography of political agency in state spatial restructuring is highlighted. To illustrate this point, I analyse the construction of new regional state spaces in Belgium, paying particular attention to the hegemonic projects that create a social basis for particular state spaces, the construction of collective agency on different scales (Belgian‐national and Flemish‐regional) and the various ways in which these processes are informed by pre‐existing state spatial and scalar selectivities.  相似文献

Abstract

As a newly emerging sub-field within human geography, carceral geography offers a unique perspective and understanding of closed spaces. Reflecting this development, three types of closed institutions provide the background for this empirical paper. The nature and experience of these spaces of confinement are explored by using in-depth qualitative interviews with young women in Scotland. The focus on gender-/age-specific characteristics and physical and spatial features reveals the processes of being ‘locked up’, of the perception of confinement and emotional responses to prison, secure care and closed psychiatry. The young women's accounts of these closed institutions are seldom heard in discourses on crime and punishment, providing an in-depth insight into these otherwise enclosed spaces. Considering the geography of three carceral systems, this study extends beyond physical detainment and works towards an understanding of the carceral experience as an emplaced, gendered, embodied, emotional and often repetitive practice. This paper is based on a larger empirical study and uses selected results of this more extensive data to exemplify ‘the carceral’ in this particular context.  相似文献

Concepts from Hierarchical Analysis of Variance (ANOVA) can be combined with ideas from geostatistics to describe the multiscale structure of spatial data. Hierarchical ANOVA involves modeling spatial data as the sum of effects associated with processes acting at different spatial scales. These effects can be modeled as stationary regionalized variables, whose spatial structure can be described using the variogram. According to this model, the variogram of the spatial data is the sum of variograms and cross‐variograms of the effects. Whereas hierarchical ANOVA reveals the relationship between scale and variability, the hierarchical decomposition of the variogram relates scale with spatial structure. This analysis method can reveal otherwise undetected features of spatial data, and can guide further analysis.  相似文献

The purpose of this article is to investigate the value of the concept of embeddedness for economic geographers. Alongside the case study of the multichannel grocery retailing brand Migros in Turkey, the spatial impacts – in relational and physical terms – of digitalization and the integration of an online shop into the profile of a supermarket chain are investigated. In applying the concept of embeddedness the article seeks to understand these complex, diverse and uneven processes of (retail) restructurings that affect different dimensions and dynamics of networks, societies and spaces. In my case study I identify two dimensions of embeddedness processes: (1) embedding the online shop in the firm's routines and practices, whereby processes of transfer of knowledge and technology dominate; and (2) embedding online shopping in the customer's routines and practices, whereby processes of adaption to consumer culture dominate. These dimensions are reflexive and as such mirror ongoing negotiation processes between the two stakeholders. On one hand multichannel retailing thus not only alters where but also how people shop, and can result in new retail spaces like pick‐up stores. On the other hand it can be shown, that the “locations”, where online shopping of Migros is available, reproduce spatial variations of socio‐economic factors, such as income distribution or population density. As such, the concept of embeddedness is useful for economic geographers – also in the realm of e‐commerce – to unravel the interconnections of societal, organizational and spatial patterns as well as their variations across space. The study is based on qualitative interviews.  相似文献

In this paper, we argue that the confinement of people on island military bases, whether narrated as humanitarian rescue, migration management, refugee resettlement, or militarized border enforcement, is an imperial process of ruination that impairs human possibility and erodes access to rights. Furthermore, the government's categorization of mobile people – as refugees, displaced, detainees, or migrants – informs the naming of these spaces, the bureaucratic and legal processes that they are subjected to, and their treatment (by local communities, federal authorities, the media, and the law). Empirical material is drawn from qualitative research conducted on US migration control in the Caribbean and Pacific. We identify spatial patterns of militarization operating across these sites, wherein migration is intertwined with enforcement, confinement, and militarization.  相似文献

This contribution searches for a regional planning conception that allows for a mutual recognition and practical translation between strategies for urban regions and peripheries beyond separate urban and rural categories; taking the Austrian strategic spatial planning context as the example. For this, various notions of polycentricity are discussed and assessed with regard to periphery. The Austrian strategic spatial development concept ÖREK sets out a focused work programme with changing responsibilities and participation of actors. The objectives are targeted and the processes are implementation oriented. Amongst other topics, urban regional issues and peripheral, declining regions are worked on separately. A conceptually integrative, plan-like strategic instrument across the topics and for the whole of Austria is lacking. The ESPON notion of ‘inner peripheries’ is proposed as a complementary concept to the ESDP notion of polycentricity, helping to create a bridge between urban regional and periphery strategies. This has the potential to guide strategic planning practice efforts in Austria towards a yet missing strategic spatial plan for the whole of the country beyond urban and rural categories. Practice relevant conclusions related to the case of Austrian strategic spatial planning are drawn and a need for further, comparative research in a European context is identified.  相似文献

By exploring the Europeanization of current practices of regional spatial planning, this article sets out to demonstrate the evolution of the European integration project. Specifically, by creating spaces of engagement to which the local and regional actors are “forced” to adapt, the emergence of European spatial planning has made planning practices at the regional level more complex and complicated. As such, the present study contributes to the current understandings of Europeanization by exploring the European integration process through the geographical conceptualizations of space and scale. These conceptualizations are used to illustrate the multidimensionality, complexity and subtlety of the geographies of Europeanization. The empirical investigations show that regional and local spatial policies are strongly engaged – both explicitly through the “technicalities” and implicitly through the “mentalities”– to the spaces of Europeanization. The engagement affects the effectiveness of sub‐regional spatial planning by promoting mismatches between the strategic frameworks and the material practices of the policy. Overall, the article illustrates that the geographies of Europeanization are continuous processes, which take place – often unrecognizably – in manifold discursive and material practices in various geographical contexts.  相似文献

以往滨海旅游研究综述大多限于对所涉研究领域的横向分类,缺乏基于特定学科演进视角下的纵向考察。本文从人文地理学空间思想演变视角出发,重新审视和梳理西方滨海旅游研究的脉络。与空间思想流变过程对应的是,西方滨海旅游研究主题也经历了从"滨海旅游地空间模型与演化"到"滨海旅游空间文化解读与社会建构"再到"滨海旅游空间政治与权力景观"的过程,亦即从关注滨海旅游空间的物质性转变到社会性和政治性。借助人文地理学空间思想演变视角,可以厘清滨海旅游研究视角转换的内在逻辑,并能从空间的生产视角重新思考中国滨海旅游的新一轮发展热潮,为国内滨海旅游研究提供新的思路和方向。  相似文献

There is a gap in research that considers, and spatializes, the everyday geographies of far-right encounters, socialization, recreation and leisure. While much research considers the end-stages of right-wing radicalisation and focuses on the extreme right (e.g., hate groups, fringe political parties, despotic leaders, specific eruptions and episodes of violence or terror, online rhetoric), the daily processes, moments and spatial configurations in-between the mainstream and extreme are sometimes overlooked. These are crucial to understand, in order to develop a more nuanced and effective language in recognizing, responding to, and combatting right-wing radicalisation.This paper thus addresses the geographical blind spot by spatializing the everyday life of the far-right, through a three-pronged taxonomy. Drawing from ethnographic observations and social media and socio-demographic analyses, the paper argues that three geographies in particular emerge as nodes of far-right formation (attached to specific sites and online/offline): a) spaces of recreation and leisure (“Celebrations”); b) spaces of faith and spirituality (“Exaltations”); and c) spaces of the corporeal (“Alpha Lands”). These spaces intersect, extend across urban, peri-urban and rural terrains, and do not necessarily adhere to established political or territorial borders and boundaries, but rather, can be envisioned as multi-scalar spatial fixes, laden with political possibilities.  相似文献

This article presents apprenticeship as an ethnographic method suitable for researching topics concerning gender and space. To use this method, the researcher takes up a practice, such as a sport. Emphasis lies in understanding one’s topic ‘by body’, and the article argues that such an embodied perspective sheds a new light on gender construction in the boxing gym. An empirical study of female amateur boxers in Scotland, conducted by the author, herself a competitive female boxer, reinforces the argument. The position of an embodied insider offers the researcher a unique vantage point with regard to various contrasting processes of gender construction on different scales, such as the body, embodied encounters and the gym. By giving attention to the transformative power of bodily practice, apprenticeship focuses on possibilities for, resistance to, and transformation of, gender norms in hyper masculine spaces. The apprenticeship method can therefore enrich geography’s understanding of the role of physical practices for gender construction in different spaces.  相似文献

This article engages with the politics of class struggle and state formation in modern Bolivia. It examines how current forms of political contestation are shaped by the legacy of the Revolution of 1952 and the subsequent path of development. In so doing, we therefore explore spaces of uneven and combined development in relation to ongoing transformations in Bolivia linked to emergent class strategies of passive revolution, meaning processes of historical development marked by the overall exclusion of subaltern classes. With this in mind we argue that state formation in Bolivia can be read as part of the history of passive revolution in Latin America within the spatial conditions of uneven and combined development shaping the geopolitics of the region. However, the expansion of passive revolution as a mode of historical development has been and continues to be rigorously contested by subaltern forces creating further spaces of class struggle.  相似文献
