再论唐六胡州城址的定位问题——兼谈历史地理学研究方法

六胡州是唐初为安置突厥降户而设置的鲁、丽、含、塞、依、契六个羁縻州府,由于其在历史研究上的重要意义,一直受到学术界关注,并取得诸多进展。但六胡州城址地望长期以来完全处于悬而不决的状态。近年来部分综合交叉研究在定位六胡州城址上取得了创建性成果,同时也引发了一些学术争议。本文拟通过历史文献考证与野外实地考察相结合的研究方法,运用城市地理学原理和3S技术手段,对相关争论进行梳理,并对其中一些城址进行了再次定位。研究认为,六胡州中鲁州确应在今宁夏盐池兴武营城址处;而匡州城址、故宥州城址和兰池都督府均处于查干巴拉嘎素古城所在,且沿用的是六胡州中的丽州或契州。     

Risk and the Arborist in the Remaking of the Australian Urban Forest

The emerging profession of arboriculture has influenced Australian urban landscapes over the past decade. Arborists manage the urban forest as a core component of urban sustainability. We analyse qualitative interviews with 53 professionals involved in tree management in six eastern Australian cities to determine the ways in which a concern with risk management has shaped both the urban forest and the professional status and role of arborists. We found tree‐related risk has, in part, worked against urban greening by reducing tree size. However, an emerging risk culture has encouraged the development of the profession of arboriculture, which, in turn, has pioneered sophisticated ways, familiar to neither engineers nor ecologists, of ensuring the cohabitation of people and trees.     

Monumentality in Urban Design: The Case of Russia

A prominent American urban geographer and observer of the Russian urban scene provides an overview of grand planning and monumental urban design in Russia and the former Soviet Union through the lens of four themes outlined in a previous paper by Larry Ford (2008). In the process, he adds two more themes relevant to Russia and the former USSR: town building and architecture intended to define and legitimize state power, and the shaping or remodeling of society to reflect a regime's ideology. Noting the obstacles in the West to getting large urban projects planned, accepted, and completed, he argues that monumental urban landscapes appear to demand some degree of sustained, centralized, authoritarian leadership. The latter has been present in Russia and the USSR during much of the past millennium, including the present, but the emergence of new commercial/corporate forces in urban land development also bears scrutiny in studies of the processes promoting urban monumentality.

Are smart cities global cities? A European perspective

Typical of the 1990s, the global cities phenomenon preceded the past decade’s massive spread of smart cities. Yet the question of how the two phenomena currently coincide remains to be considered, as well as an analysis based on viewing smart cities as global cities. An analysis related to the European scenario is developed in this article, aimed at giving a response to the previous considerations. An index is also proposed; concerning the global character of the cities, it considers the ability of the cities to attract Foreign Direct Investments (FDI). Results of the proposed analysis show that in Europe four main scenarios exist. Two regarding positive and negative correlations between the diffusion of global and smart cities, and another two scenarios demonstrate cases in which the two features are not correlated. The first two cases are respectively related to smart cities that are also global cities. The last two cases deal with the presence of different drivers that are not related to smart urban plans, which could, however, drive the attraction of FDI or which could also promote smart actions without the thrust of FDI. Correlation and regression analyses complement the work.     

Rethinking public participation in the smart city

In efforts to become “smart cities,” local governments are adopting various technologies that promise opportunities for increasing participation by expanding access to public comment and deliberation. Scholars and practitioners encounter the problem, however, of defining publics—demarcating who might participate through technology-enhanced public engagement. We explore two case studies in the city of Calgary that employ technologies to enhance public engagement. We analyzed the cases considering both the definition of publics and the level of citizen participation in areas of participatory budgeting and secondary suites. Our findings suggest that engaging the public is not a straightforward process, and that technology-enhanced public engagement can often reduce participation towards tokenism. City councillors and planners need to critically confront claims that smart cities necessarily enhance participation. Moving beyond tokenism requires understanding “public” as a plural category. Municipal governments should seek to proactively engage citizens and communities utilizing helpful resources including, but not limited to, digital tools and smart technologies. This would allow planners to keep a “finger on the pulse” of publics' concerns, better identifying and addressing issues of equity and social justice. It is also important to consider how marginalized publics can best be recognized in order to bring their concerns to the fore in decision-making processes.     

The Unstable Coastline: Navigating Dispossession and Belonging in Colombo

This article explores how residents of a small coastal fishing enclave in Colombo live with cumulative waves of dispossession brought on by exclusionary projects of urban development. Drawing on ethnographic fieldwork, I introduce the analytic of navigation to describe how people move, plan and live with both present and future threats of dispossession. Navigation offers a unique perspective on questions of agency and resistance in oppressive conditions. Rather than framing subjects as “resisting” projects of world-class city-making, this analysis shows that urban residents instead engage in complex and occasionally contradictory modes of living with uncertainty. I complicate existing understandings of the term “navigation” by describing how questions of nation and belonging are crucial to comprehending how people navigate. Ultimately, I suggest that expressions of belonging and obligation to an imagined community might not only be strategic, but instead reflect some of the broader social forces which structure possibilities for action.     

Where cities fail to triumph: The impact of urban location and local collaboration on innovation in Norway

The role of cities in fostering innovation has for long been taken for granted. Agglomeration and the knowledge spillovers generated in dense urban environments have been considered fundamental drivers of innovation. This view has, however, become challenged by research questioning the returns to physical agglomeration and local networking, placing instead more emphasis on the importance of interregional and international collaboration, and on innovation in peripheral regions. This paper delves into the debate on the role of cities for innovation by examining the interplay between urban location and local collaboration in Norway. It uses data from the Community Innovation Survey for 2006–2010 to map out the geographical dimension of R&D collaboration in Norwegian firms with a view to assessing whether different types of R&D collaboration in urban and rural locations affect firms’ propensity to innovate. The results show that local collaboration is associated with increased process and organisational innovation, while it does not produce higher levels of product or marketing innovation. Conversely, international collaboration is connected with higher probabilities of product, new-to-market and marketing innovations. Furthermore, location in urban or rural areas makes no difference for most innovation outcomes in Norway when other characteristics are controlled for. Location in cities also does not shape the returns to local R&D collaboration. Hence, the role of cities for innovation in Norway, whether in themselves or as sites for dense local interaction, is less relevant than the urban innovation literature would predict.     

Regional inequality in the U.S.: Evidence from city-level purchasing power

Using quarterly data for 42 products over the period from 1990 to 2015, we find that there has been a large and growing dispersion of purchasing power across U.S. cities since 1990 and the dispersion varies widely across products. We also find that total factor productivity shock precedes or predicts the rise in regional inequality of purchasing power. We view that the growing regional inequality found in the purchasing power among U.S. cities might have proceeded after nationwide productivity shocks mainly by the cities with higher share of skilled workers through the products with more flexible price adjustments.     

Passing as a tourist: Exploring the everyday urban geopolitics of tourism

This paper presents a case study of territorial boundary transgression and intergroup encounters mediated by tourism in a volatile and contested urban space. I present the notion of ‘passing as a tourist’ as a prism to investigate the nexus between performative tourism and everyday urban geopolitics. Situated in East Jerusalem's core geographies of colonization and political violence, this paper uses archival news material and a textual analysis of primary questionnaire data to critically examine how Jewish Israeli Jerusalemites visiting the Muslim Quarter in the Old City negotiate encounters in a conflicted space. The study reveals how the performative dimensions of ‘tourism’ in a context of polarized ethnonational division expose the role of embodied, everyday geopolitics in the production of urban spaces of tourism.     

What makes people stay in or leave shrinking cities? An empirical study from Portugal

The attractiveness of cities as places to live determines population movements into or out of them. Understanding the appealing features is fundamental to local governments, particularly for cities facing population decline. Pull and push attributes can include economic aspects, the availability of amenities and psychological constructs, initiating a discussion around which factors are more relevant for migration. However, such discussion has been underexplored in studies of shrinking cities. In the present study, we contribute to the discussion by identifying pull and push factors in Portuguese shrinking cities. Data were collected using a face-to-face questionnaire of 701 residents in four shrinking cities: Oporto, Barreiro, Peso da Régua and Moura. Factor analysis and automatic linear modelling were used to analyse the data. Our results show that the economic activity is the most relevant feature for retaining residents. However, characteristics specific to each city, related to heritage and natural beauty, are also shown to influence a city’s attractiveness. The cause of population shrinkage was also found to influence residents’ assessments of the pull and push attributes of each city. Furthermore, the results show the relevance of social ties and of place attachment to inhabitants’ intention to continue living in their city of residence.
