This paper examines the spatial patterns of unemployment in Chicago between 1980 and 1990. We study unemployment clustering with respect to different social and economic distance metrics that reflect the structure of agents' social networks. Specifically, we use physical distance, travel time, and differences in ethnic and occupational distribution between locations. Our goal is to determine whether our estimates of spatial dependence are consistent with models in which agents' employment status is affected by information exchanged locally within their social networks. We present non‐parametric estimates of correlation across Census tracts as a function of each distance metric as well as pairs of metrics, both for unemployment rate itself and after conditioning on a set of tract characteristics. Our results indicate that there is a strong positive and statistically significant degree of spatial dependence in the distribution of raw unemployment rates, for all our metrics. However, once we condition on a set of covariates, most of the spatial autocorrelation is eliminated, with the exception of physical and occupational distance. Racial and ethnic composition variables are the single most important factor in explaining the observed correlation patterns. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

‘Education–migration nexus’ policies in Australia between 1998 and 2010 linked international education with different forms of temporary and permanent migration. This resulted in a blurring of boundaries around student, worker, consumer, migrant and ethnic identities. While the exploitation, marginalization and vulnerability of international students in Australia has gained a great deal of media and scholarly attention, less consideration has been given to the varied forms of subsequent protest undertaken by student migrants in Australian cities. This article analyses three case studies of protests involving student migrants in Melbourne: a protest against unfair assessment; a fight for a campus prayer room; and labour protests within the retail service and taxi industries. It draws on theoretical work on new social movements and social transformation in urban spaces to find ways to conceptualize this activism in relation to the scales of campus, city and nation. In doing so, it argues primarily that these sites of protest are socio‐spatial experiences that encompass shifting and socially produced spatial scales, as well as complex networks of association across different communities, which in turn reflect different student‐migrant identities.  相似文献

Discussions about socio‐spatial integration in the US have been primarily focused on research into residential segregation. The treatment of these two concepts as opposites has had two consequences. First, most policies for integration have been based solely on concepts of segregation. Second, the intensive criticism directed at integration flows more from those policies than from its conceptual meaning. This article develops a framework for socio‐spatial integration. It does this first by outlining an understanding of segregation and the complexities of its treatment, then by making a distinction between policy applications and the conceptual meaning of integration. This review shows that, rather than suiting a linear approach, socio‐spatial integration can be expressed as a multidimensional relationship that may work independently and at different scales. Socio‐spatial integration is then exposed as the opposite of social exclusion, of which physical proximity between different social groups is just one dimension. Two lines of research are proposed: first, a repositioning of integration as a progressive aspiration and a critique of naturalist conceptions; second, a balancing of the weight of spatial proximity among the different dimensions of integration.  相似文献

This article takes the contemporary transformation in electricity access in Rio de Janeiro's favelas as a starting point for a broader review of the relationship between the right to the city in informal settlements and the neoliberalization of the electricity service (introduction of full cost recovery and ‘the user pays' principle). It examines the socio‐technical process through which contractual customer relationships have been established or restored through regularization of the electricity service in two favelas, namely, the installation of meters and networks. I suggest that applying a science and technology study perspective to the right to the city helps explore both the materiality and the spatial dimension of power and politics and, in so doing, provides an insight into some of the forms of mediation that help reshape recognition, urban practices and the favela dwellers' position within such an essential service. Our analysis shows how the means of recognizing these city dwellers ‘by the network' are materially and symbolically reshaped by commercial processes. The question then is whether this right to the city, which is being reshaped by commercial processes, will be the source of new inequalities or new politicizations.  相似文献

Cities confronted with unsustainable development and climatic changes are increasingly turning to green infrastructure as an approach for growth and climate risk management. In this context, recent scholarly attention has been paid to gentrification, real‐estate speculation and resident displacement in the context of sustainability and green planning in the global North. Yet we know little about the environmental‐justice implications of green infrastructure planning in the context of self‐built settlements of the global South. To what extent do green infrastructure interventions produce or exacerbate urban socio‐spatial inequities in self‐built settlements? Through the analysis of a greenbelt project, an emblematic case of green infrastructure planning in Medellín, we argue that, as the Municipality of Medellín is containing and beautifying low‐income neighborhoods through grabbing part of their territories and turning them into green landscapes of privilege and pleasure, communities are becoming dispossessed of their greatest assets—location, land and social capital. In the process, community land is transformed into a new form of aesthetically controlled and ordered nature for the middle and upper classes and for tourists. By contrast, communities’ planning alternatives reveal how green planning can better address growth and climate risks in tandem with equitable community development.  相似文献

During the 1980s, Singapore's policy‐makers perceived that the continued expansion of the Singapore economy required more spaces and workers beyond the 680‐square‐kilometre territorial limits of the city‐state. While planning to extend these limits through further land reclamation, Singapore also began to foster economic cooperation with regional neighbours, most famously in the form of a so‐called Growth Triangle incorporating proximate areas of Malaysia and Indonesia. The empirical focus of this article is on the tourist enclave developed on the Indonesian island of Bintan, a 45‐minute ferry ride from Singapore. This enclave embodies complex re‐territorializations. We specify how, despite a decade of re‐fashioning zones of Bintan into quasi‐enclaves and the literal and metaphorical cultivation of a tourist haven, other claims on these transfrontier zones resurfaced in the form of resistances and struggles over the terms of access to land and resources. It is argued that the trajectory of Bintan is symptomatic of wider transformations and epitomizes new configurations of sovereignty, urbanity and ‘gated globalism’.  相似文献

In addressing the notion of team ambidexterity, we propose that socio‐psychological factors (i.e., team cohesion and team efficacy) may help team members to resolve paradoxical challenges and to combine exploratory and exploitative learning efforts. In addition, we theorize that senior executives may play an important role in facilitating the emergence of ambidexterity at lower hierarchical levels. In doing so, we develop a multilevel contingency framework and propose that the effectiveness of teams to achieve ambidexterity is contingent upon supportive leadership behaviours at the organizational‐level. Using multilevel, multisource, and temporally separated data on 87 teams within 37 high‐tech and pharmaceutical firms, we not only reveal how team cohesion and efficacy may matter for the emergence of team ambidexterity but also show that the effectiveness of supportive leadership behaviours from senior executives varies across cohesive and efficacious teams.  相似文献

Socio‐emotional wealth (SEW), defined as the firm's non‐financial aspects meeting the family's affective needs, has become the dominant paradigm in family firm research. Recent debate acknowledges potential SEW heterogeneity within family firms. This study considers the effect of polarizing opinions on SEW preservation among TMT members as a source of separation in the TMT. More concretely, we study the effect of SEW separation on TMT decision‐making quality, while taking into consideration behavioural integration as a team process and psychological safety as a team context. Based on a unique multiple respondent sample of 300 managers from 55 Belgian private family firms, we find that behavioural integration mediates the negative effect of SEW separation on TMT decision‐making quality. In addition, we find that the negative effect of SEW separation on behavioural integration is mitigated by psychological safety and even turns into a positive effect at high levels of psychological safety.  相似文献

This article extends the literature on CEO succession and financial performance by addressing corporate owners' mixed motives and desires to protect their interest in being in business. We draw on a Socio‐Emotional Wealth (SEW) perspective to investigate how the choice of one of three succession mechanisms – relay succession, ‘horse races’ among internal CEO candidates, and hiring from outside – may effectively balance trade‐offs between corporate owners' non‐financial SEW motives and the firm's financial performance. We find that implementing one of these succession mechanisms reduces the negative impact that typically characterizes CEO transitions in family firms. We also show that family presence on the board of directors offsets the benefits of having selected these balancing succession mechanisms, in either placing too much emphasis on SEW, or creating negative dynamics that make the chosen succession mechanisms less effective.  相似文献

In many cities around the world we are presently witnessing the growth of, and interest in, a range of micro‐spatial urban practices that are reshaping urban spaces. These practices include actions such as: guerrilla and community gardening; housing and retail cooperatives; flash mobbing and other shock tactics; social economies and bartering schemes; ‘empty spaces’ movements to occupy abandoned buildings for a range of purposes; subcultural practices like graffiti/street art, skateboarding and parkour; and more. This article asks: to what extent do such practices constitute a new form of urban politics that might give birth to a more just and democratic city? In answering this question, the article considers these so‐called ‘do‐it‐yourself urbanisms’ from the perspective of the ‘right to the city’. After critically assessing that concept, the article argues that in order for do‐it‐yourself urbanist practices to generate a wider politics of the city through the appropriation of urban space, they also need to assert new forms of authority in the city based on the equality of urban inhabitants. This claim is illustrated through an analysis of the do‐it‐yourself practices of Sydney‐based activist collective BUGA UP and the New York and Madrid Street Advertising Takeovers.  相似文献

This article introduces an innovative, experimental, adaptive, and iterative approach to creating legal and institutional frameworks based on urban polycentric governance to foster commons‐based urban policies. First, the theory of urban/local governance is introduced, based on an urban co‐governance matrix. A new type of regulatory system is then described that aims at transforming people in distributed nodes of collective action. Citizens and institutions can be myriad nodes of designing and problem solving in the public interest. Urban co‐governance aims at taking advantage of this galaxy of networks. I then examine design principles and a methodology to implement the urban co‐governance matrix. The concluding question concerns the need for a new research methodology to investigate the ongoing process of state transformation and institutional genesis at the urban level.  相似文献

Drawing upon social cognitive theory, this research postulates cultural intelligence as a key driver of knowledge sharing among culturally diverse teams. An empirical testing of the proposed model, by investigating team leaders from high‐tech industries, reveals the applicability of social cognitive theory in understanding cultural intelligence, perceived team efficacy, and knowledge sharing. Specifically, the test results herein show that knowledge sharing is directly influenced by metacognitive, cognitive, and motivational cultural intelligence. At the same time, knowledge sharing is indirectly impacted by metacognitive and behavioral cultural intelligence through the mediation of perceived team efficacy. Lastly, this research provides managerial implications and limitations. © 2013 Wiley Periodicals, Inc.  相似文献

Companies increasingly make use of geographically dispersed teams to capture knowledge residing at different locations. In this context, shared leadership is considered a key enabler of team performance. Taking a functional perspective on shared leadership, we thus investigate the relationship between shared leadership behaviors and team performance in dispersed teams. Furthermore, we analyze how socio‐demographic factors that are characteristic for dispersed teams (i.e., high female‐to‐male ratio, high mean age, and high levels of national diversity) affect shared leadership behaviors. Based on data from 96 dispersed teams, we show that shared leadership behavior fosters team performance. Further, we find the socio‐demographic characteristics typical for dispersed teams to foster shared leadership. Theoretical and managerial implications for human resource management are discussed. © 2012 Wiley Periodicals, Inc.  相似文献
