Teaching of critical spatial thinking in higher education empowers graduates to effectively engage with spatial data. Geographic information systems (GIS) and science are taught to undergraduates across many disciplines; we evaluate how this contributes to critical spatial thinking. The discipline of GIS covers the whole process of spatial decision-making, but GIS modules often ignore the context setting of spatial problems, and just cover the technical aspects of how to use GIS software. We outline how some existing GIS practicals could be improved to focus on the development of critical spatial thinking skills, competences and abilities that are valuable to graduates.  相似文献

Recent discussions on state rescaling have pointed towards the need for a greater focus on how and why state activity may change over time in order to generate insights into the provenance, trajectories and outcomes of rescaling in different global regions and national state spaces. Consequently, this paper explores the dialectical and recursive relationship between the concepts of “statecraft” and “scalecraft” to explore the evolving sites, objects and mechanisms for urban planning within two key urban centres in different parts of the world—Birmingham, UK, and Brisbane, Australia. It is illustrated how a range of actors—from the national to the local level—have sought to craft and reshape the strategies and structures for urban planning according to different imperatives. In turn, the implications for a tighter specifying of the process of state rescaling are considered, as well as the subsequent nature of urban planning arrangements.  相似文献

In polycentric urban regions several distinct cities, none of which is dominant, cooperate and compete with each other to attract inhabitants and firms. In such settings city branding strategies do not solely affect one city, but the entire region. We examined how city branding in the face of ecological modernization, that is, delivering higher added economic value, while lowering environmental impacts, is playing out in the Dutch Randstad and the German Rhine-Ruhr. Our findings show that regional identity formation occurs at the sub-polycentric urban region level, coinciding more with (historical) economic profiles than with planning imaginaries. The Dutch cities profile themselves more along the lines of ecological modernization than their German counterparts. Differences between subregions within each polycentric urban region are also noticeable, where more industrialized regions, such as the Ruhr or southern Randstad focus on ‘green’, ‘liveable’ and ‘knowledge-oriented’, while cities with stronger knowledge-intensive sectors portray themselves as ‘smart’ or ‘sustainable’. Cities generally substantiate their profiles through projects, but a significant gap persists between reality and aspirations for improved environmental conditions. This is especially true for the Dutch cities, where many claims, but little visible action can be observed.  相似文献

The literature shows that market size favours firms’ vertical disintegration because it reduces transaction and knowledge coordination costs. The existing evidence is based primarily on cross-sectional data and on the manufacturing sector, with little or no attention is given to longitudinal data and services. This paper estimates the effect of urban size on the purchase of service inputs by knowledge-intensive business service firms located in the metropolitan region of Milan. Relying on a rich panel dataset, and adopting different econometric techniques to overcome endogeneity, we find a positive and statistically significant effect of increased urban population on the degree of KIBS vertical disintegration only when urban size is measured at the province level. We also find that this effect holds particularly in the case of traditional professional- rather than technology-related activities.  相似文献

Within the debates about the socio-economic advantages of cohesive urban regions, several barriers to institutional integration are said to exist, especially when a metropolitan government is absent and integration relies on inter-municipal cooperation. Some barriers are associated with different urban region structures, such as the asymmetric power relations and sociocultural contrasts between municipalities in systems with dominant core cities, or the lack of a leading city to overcome fragmentation and provide a shared identity in polycentric urban regions (PURs). This paper investigates whether urban regions formed around second-tier cities, whose features depart from both dominant core and PUR models, are able to mitigate these barriers when pursuing integration strategies. The analysis relies on interviews with municipal leaders in three representative European case studies, examining how they perceive the barriers to inter-municipal relations in second-tier urban regions. The findings show that perceptions vary not only between regions, with the three cases following different trajectories of integration, but also within regions, according to the geographical and socio-economic context of municipalities and the legacy of past relations. In general, barriers to integration are not minimized without explicit efforts to rebalance power relations, approach political cultures, mobilize core city leadership and develop a metropolitan identity.  相似文献

Gender differences in mobility patterns between women and men have long been acknowledged. This study analyses how these differences are reproduced in different urban and rural contexts. Using mobility data from a large travel survey taken in 2006 in Spain, we examine the differences between gender mobility through age, modal split and trip purposes. Special attention is paid to how territory shapes mobility and how these territorial settings differently affect gendered mobilities. The use of this data source allows the comparison of all trips made by the total population, including all means of transport. By taking a global view on mobility, the uneven relationships that men and women have with different means of transport become more visible. After disaggregating data by age and territorial settings, results show that women are using sustainable transport modes more often than men, and travelling for more diverse reasons. Gender is thus a fundamental variable in understanding modal split and, by extension, transport sustainability, in terms of energy consumption and the emission of greenhouse gases. From this point of view, we consider women's mobility knowledge and practices – typically related to the most sustainable means of transport – as factors with rising value that could effectively guide public policy in its way to promote more sustainable mobility patterns.  相似文献

In November 2012, a researcher, two social workers and five mothers embarked on a participatory action research (PAR) journey with the aim to develop new ideas for interventions for children and young people in street situations of the city of El Alto in Bolivia. In this article, we attend to the topic of personal and social transformation in PAR. We explore how the mothers of young people in street situations perform and negotiate their subjectivities as mothers in their everyday life; how they create (new) subjectivities in exchange and in interaction with each other during the mother project; and how the performance of their (new) subjectivities can bring social change. The mothers in our group shared stories of being silenced by social services in their everyday lives, as their motherhood is declared not good enough or as they are perceived too guilty to claim for help. It was the first time the mothers shared their stories with other mothers of their lives with their children in street situations. By noticing that they all experienced or heard of similar events that their children were subjected to in the streets, the mothers grew confident enough to talk back. Mothers talked back by denouncing injustice and by transforming doubts into questions, providing them with more knowledge. Finally, as the mothers reached out to social services, mothers’ presence, questions and stories confronted aid workers with their own flaws, and their comfortable discourse of blaming families, creating new paths towards social transformation.  相似文献

Individualisation, which is increasingly promoted in European welfare states, tends to be absent from policy discourse as well as housing studies in Japan. It is largely because the ‘family as a unit’ is still a dominant approach in their household finance, social security and taxation systems, which also reflects women’s lack of home ownership. However, recent demographic trends such as falling marriage rates, low fertility and increased female labour participation indicate significant diversification in women’s life-course. Thus, today women making their own financial investment and house purchase have increasingly become popular practice. In this context, a new approach beyond the conventional ‘family as a unit’ may be required in the development of a new social contract. Drawing on data from qualitative research conducted among women in their 30s, this article explores the relationship between financial independence, household decisions and asset holding of partnered women in Japan, which reveals contested dimensions of women’s independence and autonomy in household and family life. Through the lens of home ownership, it considers the importance of promoting individual assets in order to foster gender equality in marriage.  相似文献

Recognition and respect for sexual minorities in Hong Kong is still a contested area. Public sexual identity politics in Hong Kong has been framed by traditional Chinese gender ideology and imported Christian beliefs which are profoundly negative. Focusing on the interpersonal relationships in three spheres of life, the research adopted the sociological perspective of personal life and the feminist geographers’ idea of spatialization of identity management to analyze how the sexual self of sexual minorities has been marginalized and excluded in intimate social spaces of family, church communities and schools in Hong Kong with specific spatial practices and different forms of power/knowledge. By examining overlooked intimate injustice in personal life, this study illustrates that identity conflicts between Christianity and non-heterosexuality in everyday life is constructed through misrepresentation, misrecognition, harassment and exclusion in intimate relationships. Different types of knowledge are being used to reiterate pre-existing norms and institutionalized patterns of cultural value that constitute the sexual minorities as comparatively unworthy of respect. These micro-political processes involve both conformity and resistance to gender and sexual stereotypes. Participants managed to develop spatial coping strategies such as concealment, compartmentalization, confrontation and alternative sources of support to manage their lives with dignity and self-esteem.  相似文献

Drawing on a detailed analysis of the historical and current development of lighting in Copenhagen’s Tivoli Gardens, this article addresses how this site of extraordinarily diverse illumination exemplifies a carefully orchestrated balance between (1) muted and more vivid forms of lighting, (2) curation of historical styles and promotion of contemporary innovations in illumination and (3) artistic luminaires and those more aligned with popular tastes. Through these themes, we argue that the current strategies towards urban lighting that predominantly promote energy conservation, security, commercial imperatives and place-branding may be supplemented by place-specific design strategies that implement multiplicity, connect past and present, and accommodate diverse desires, dreams and realities. These attributes contribute to the ongoing emergence of what we call a ‘lumitopia’, a space in which an intensified attention to illumination is integral to the particularity of a place or landscape. In the case of Tivoli, this offers a lens to manage nocturnal space so that it becomes more aesthetically complex, inclusive and convivial.  相似文献
