城市居民环城游憩距离选择的实证研究——以长沙市为例

本文通过抽样调查所获取基础数据,对城市居民环城游憩距离选择进行了实证研究,发现城市居民环城游憩活动并不完全符合距离衰减规律,而是存在出游理想距离。理想距离范围内是城市居民到访率最高的区域,形成环城游憩密集带。通过理想距离与游客性别、年龄、收入、文化程度、职业等交叉列联表分析,得出城市居民出游理想距离选择的差异性。在此基础上,本文探讨了城市居民环城游憩活动理想距离的形成机理,认为这是在各种因素共同影响下,在三大作用力系统——推动力系统、阻碍力系统、交互力系统相互作用下的一种均衡结果。     

泰州水关遗址结构分析及修缮设计

水关是古城墙建筑的一个重要元素,对研究古城墙布局及城市演变具有重要意义。为了对泰州水关遗址进行科学保护,首先通过现场调研,对泰州水关遗址的残损进行分析,找出其可见的病害,包括墙体残损、基础残损、券体残损及木桩残损;然后通过有限元模拟分析其结构性能,找出其隐在的病害,主要是地基和墙体问题。最后,综合残损调研及数值模拟结果,提出了适用于水关遗址的修缮设计方法,包括地基加固、墙体加固以及木桩保护方法。     

Urban shrinkage: an unspoken challenge of spatial planning in Russian small and medium-sized cities

Shrinkage since the collapse of state socialism has been evident in many Russian cities, especially in small and medium-sized (SMS) ones. The Russian state, de jure, has been promoting the idea of self-governance; thereby, urban municipalities ought to develop and adopt own planning decisions to cope with various challenges, including those related to depopulation. The current research focuses on planning responses to urban shrinkage. It aims at understanding how the phenomenon is conceptualized in the planning documents of Russian SMS cities and what solutions are proposed to cope with it in the conditions inherited from the Soviet times housing and infrastructural deficit. The empirical evidence for the analysis is drawn from over 70 SMS cities located in Central and Southern Russia. Results state that despite obvious and persisting urban shrinkage, most of the reviewed documents ignore or underestimate the phenomenon. Instead of suggesting flexible solutions, which would help overcome the shortage of urban infrastructure not aggravating shrinkages’ effects in the cityscape, long-term spatial plans are being developed with hope for future growth proposing measures that contribute to the intensification of urban sprawl and fragmentation.     

City with or without God? Features of post-secularism in religious landscape of post-communist Prague

The religious climate caused significant changes over the last few decades which led to intense debates about post-secularism in Western Europe. However, there is particularly a distinct lack of analyses of the features of post-secularism in post-communist cities. The paper draws on the case study of Prague where the religious landscape is in many ways unique in a European context because of its highly secularized society. Nevertheless, Prague also experienced a revival of religious life, which has found expression in the religious landscape (not only) through the emergence of new sacral structures, pluralization of religion and post-secular rapprochement in religious institutions. The paper examines the convergent and contradictory processes shaping the religious and non-religious landscape in Prague and therefore opens the discussion about post-secularism in post-communist context. The results point to the importance of historical, social, and urban development for the new geographies of religion. New areas of research should also draw attention on the new religious movements and alternative spirituality which helps to explain the relationship between sacred and secular phenomena in current European society and space and the re-definition of the minority role of religion in the secular society.     

Solutions and frictions in civic hacking: collaboratively designing and building wait time predictions for an immigration office

Smart and data-driven technologies seek to create urban environments and systems that can operate efficiently and effortlessly. Yet, the design and implementation of such technical solutions are full of frictions, producing unanticipated consequences and generating turbulence that foreclose the creation of friction-free city solutions. In this paper, we examine the development of solutions for wait time predictions in the context of civic hacking to argue that a focus on frictions is important for establishing a critical understanding of innovation for urban everyday life. The empirical study adopted an ethnographically informed mobile methods approach to follow how frictions emerge and linger in the design and production of queue predictions developed through the civic hacking initiative, Code for Ireland. In so doing, the paper charts how solutions have to be worked up and strategies re-negotiated when a shared motivation meets different data sources, technical expertise, frames of understanding, urban imaginaries and organisational practices; and how solutions are contingently stabilised in technological, motivational, spatiotemporal and organisational specificities rather than unfolding in a smooth, linear, progressive trajectory.     

Architectural rumors: unrealized megaprojects in Baku,Azerbaijan and their politico-economic uses

This article examines the agency of unrealized megaprojects in bolstering economic activity, legitimizing political regimes, and expanding designer’s portfolios. It argues that such proposals serve as a form of “Architectural Rumor,” providing politico-economic agency despite ultimate project infeasibility. Specifically, it looks at two case studies of proposed yet unrealized island megaprojects in the city of Baku, Azerbaijan: the 2009 Zira Island Master Plan and the 2010 Khazar Islands Plan. Spectacular urban design and architecture have long served as catalysts for development, investment attraction, and real estate speculation. As cities compete with one another to lure capital and boost their global status, many design proposals have become increasingly expensive, ostentatious, and technologically sophisticated. The high-risk financial nature of grand urban design proposals and their frequent associations with displacement or environmental destruction suggests that the megaproject model is becoming flawed. At the same time, there remain advantages for clients and politicians to proposing designs that are more spectacular than feasible. Using a mixed-methods approach, four key arenas in which unrealized proposals circulate are described. The various benefits and detriments of such an approach to architectural commodification are also discussed, foregrounding the broader societal costs.     

多类型微博舆情时空分布关系的差异性及其地理规则

以新浪微博转发行为作为舆情时空分布的研究对象,分别选取4·20雅安地震事件代表重大社会舆情、凤凰古城收费事件代表公众生活舆情、郭某某事件代表网络热点舆情3类案例,总结不同类型微博舆情的时空分布特征及差异性,进而透视客观存在的地理规则。研究发现：①3类舆情事件微博转发量的时间分布分别表现为：长尾型、山峰型、多个时间段上的波浪型。②与时间轴对应的空间分布呈等级结构,信息扩散节点城市等级（转发量）结构还会表现出一定的空间伸缩变形或与距离衰减形成叠加关系,3类事件分别表现为：延续传统规律的“始终金字塔”结构、在相对较长时间过程中具有范围伸缩的“始终金字塔”结构、距离衰减影响下的“始终金字塔”结构。城市规模效应主导和距离摩擦阻尼效应影响构成网络信息空间分布的基本地理规则。③微博舆情时空分布的差异性与事件类型有关,并与不同微博用户的作用有关。微博用户的不平衡区域分布和其跨区域流动对信息空间分布产生直接影响。     

Property and Propriety: Jewish Landlords in Early Twentieth-Century Toronto

Drawing on literatures on the social construction of place and identity, and on the changing nature of urban property ownership, this paper examines Jewish immigrants to Toronto as housing landlords, situating their activities in the context of wider changes in the city's housing market and of their needs to raise capital, achieve status and foster group identity. Using archival and newspaper evidence to reconstruct the behaviour of individual landlords, it is argued that ownership of inner-city property fulfilled numerous functions, especially related to other aspects of business proprietorship, but that it also accentuated the geographical concentration of poorer Jews, with critical implications for their relations with non-Jews.     

战国时宋都彭城辨

钱穆著<战国时宋都彭城证>提出十五证并二事,以为战国时"宋都彭城,不都睢阳,断可定矣."查钱氏提出的诸证据没有一条是直接的,都为推测之论,而且存在很多问题,于直接说到战国时彭城属楚属齐的材料也没有提出很好的解释.通过对钱先生有关论述之辨析,及诸多反证之综合讨论,宋都彭城(今江苏徐州市)说实不可信."宋"与"相"古为双声叠韵字,"相城"实即"宋城"之异写,再参考其他一些旁证资料,说战国时宋国迁都于相城(今安徽淮北市),可能性要更大一些.     

Care‐full Justice in the City

Feminist theorists in geography and beyond have long been calling for an ethic of care to be considered alongside justice as a normative ideal that can assist us in repairing our world. In urban theory this call has largely remained unheard as an ethic of care remains absent from theorisations of what comprises a just city. In this paper I argue for care to be considered alongside justice as an equally important ethic in our search for justice in the city. I develop the concept of care‐full justice, which assists us in negotiating the inherent tension between the normative and situated in the search for the ideals, and actually existing expressions, of justice and care in the city. I demonstrate the generative potential of this concept and argue that it enables us to re‐think what cities can be and to reveal times and places where this is the case.
