Remaking Equality: Community Governance and the Politics of Exclusion in Bogota's Public Spaces

Bogota's public space policy is often credited with promoting inclusionary principles. In this article, I explore critically the content of Bogota's articulation of equality in public space policy. In so doing, I present a critical view of the work Bogota's insistence on equality does to mediate class relations in the city, relying on deeply held conceptions of both social extremes. This results in the construction of a version of social harmony in public space that at once depoliticizes the claims to public space of subjects such as street vendors and the homeless and claims a new role for the middle class in the city. The analysis focuses on two examples of community governance schemes, documenting the logics and methods used by communities to implement official visions of equality and justify the exclusion of street vendors and homeless people from the area. By looking at the articulation of these exclusions in local class politics through seemingly inclusionary rhetoric, the article accounts for ‘post‐revanchist’ turns in contemporary urban policy, while anchoring its production in local processes of community governance.

Licensing,Popular Practices and Public Spaces: An Inquiry via the Geographies of Street Food Vending

The socio‐legal technology of licensing is one of the primary tools governments use to manage spaces and practices deemed risky or threatening to public order. Licensing requirements thus play a crucial role in shaping routine experiences in public space as well as the trajectories of emerging forms of public life. Yet licensing laws have largely been ignored in critical urban scholarship: too often concerned with the interpretation and critique of popular practices and public spaces, the mundane operations of urban governance are often left to practitioners and policy researchers. This article demonstrates how paying closer attention to licensure can provide valuable and unexpected insights into matters of social equality, urban amenity and economic opportunity. It does so through a comparative inquiry into practices of street food vending in New York City, Seattle, and Portland, Oregon. Drawing on ethnographic study and interviews, the article demonstrates how licensing can be involved in the production of quite peculiar and unjust geographies of practice, but also how shifts in popular culture can force a reconsideration of taken‐for‐ granted laws. In conclusion, it is argued that a focus on licensing offers a productive pathway for new forms of critical urban research and provides a potential point of leverage in efforts to configure better and more democratic forms of urban public life.     

Macro‐integration with inequality constraints: an application to the integration of transport and trade statistics

Macro‐integration is the process of combining data from several sources at an aggregate level. We review a Bayesian approach to macro‐integration with special emphasis on the inclusion of inequality constraints. In particular, an approximate method of dealing with inequality constraints within the linear macro‐integration framework is proposed. This method is based on a normal approximation to the truncated multivariate normal distribution. The framework is then applied to the integration of international trade statistics and transport statistics. By combining these data sources, transit flows can be derived as differences between specific transport and trade flows. Two methods of imposing the inequality restrictions that transit flows must be non‐negative are compared. Moreover, the figures are improved by imposing the equality constraints that aggregates of incoming and outgoing transit flows must be equal.     

Board Antecedents of CEO Duality and the Moderating Role of Country‐level Managerial Discretion: A Meta‐analytic Investigation

CEO duality reduces boards’ monitoring capacity. But governance substitution theory holds that boards of directors who can effectively monitor their CEOs are more likely to adopt the CEO duality governance structure. By examining relationships between board characteristics underlying their monitoring capacity and CEO duality, we bring evidence to bear on governance substitution theory. Further, by applying a managerial discretion theory lens to CEO duality, we extend governance substitution theory to the cross‐country context where institutional features vary in their constraints on managerial discretion. Meta‐analytic results from a dataset of 297 studies across 32 countries/regions provided support for the majority of our predictions. As predicted, board independence and certain types of board human capital were positively related to CEO duality. Unexpectedly, board ownership was negatively related to CEO duality. Additionally, country‐level managerial discretion significantly moderated the board independence‐ and human capital‐duality relationships (but not the board‐ownership‐duality relationship) as predicted.     

Delivering Flagship Projects in an Era of Regulatory Capitalism: State‐led Privatization and the London Olympics 2012

Much of the urban studies literature on the London Olympics has focused on its social legacies and the top‐down nature of policy agendas. This article explores one element that has been less well covered — the contractual dynamics and delivery networks that have shaped infrastructure provision. Drawing on interviews and freedom of information requests, this article explores the mechanisms involved in the project's delivery and their implications for broader understandings of urban politics and policymaking. It assesses contemporary writings on regulatory capitalism, public–private networks and new contractual spaces to frame the empirical discussion. This article argues that the London Olympic model has been characterized by the prioritization of delivery over representative democracy. Democratic imperatives, such as those around sustainability and employment rights, have been institutionally re‐placed and converted into contractual requirements on firms. This form of state‐led privatization of the development process represents a new, and for some, potentially more effective mode of governance than those offered by traditional systems of regulation and management.     

Beyond the Urban–Suburban Divide: Urbanization and the Production of the Urban in Zurich North

Starting from current debates on ‘global suburbanism' and ‘postsuburbia', this article explores the changes that the former ‘urban periphery' of Zurich North has experienced in the last three decades. It mobilizes Henri Lefebvre's triadic concept of conceived, perceived and lived space in aid of an analysis of the profound urban transformations that can be observed. The construction of a new tramline serves as a guideline for an analysis of the implementation of new governance arrangements strengthening cross‐border cooperation between individual municipalities and new strategies of cooptation and expertise. This resulted in the production of new urban structures which led to a more densely woven and connected urban fabric primarily providing spaces for the headquarter economy and middle‐class housing. Concomitantly, great efforts have been made to create new public spaces, an urban image and even an urban atmosphere. These have proved at least partially successful, thus promoting a symbolic redefinition of the former urban periphery as a distinctively ‘urban' space. Conventional definitions and concepts no longer suffice to adequately understand such novel urban forms, leading to the conclusion that division into an ‘urban' and a ‘suburban' world is no longer a useful tool for urban analysis.     

Localised Estimates of Dynamics of Multi‐dimensional Disadvantage: An Application of the Small Area Estimation Technique Using Australian Survey and Census Data

Deep and persistent disadvantage is an important, but statistically rare, phenomenon in the population, and sample sizes are usually not large enough to provide reliable estimates for disaggregated analysis. Survey samples are typically designed to produce estimates of population characteristics of planned areas. The sample sizes are calculated so that the survey estimator for each of the planned areas is of a desired level of precision. However, in many instances, estimators are required for areas of the population for which the survey providing the data was unplanned. Then, for areas with small sample sizes, direct estimation of population characteristics based only on the data available from the particular area tends to be unreliable. This has led to the development of a class of indirect estimators that make use of information from related areas through modelling. A model is used to link similar areas to enhance the estimation of unplanned areas; in other words, they borrow strength from the other areas. Doing so improves the precision of estimated characteristics in the small area, especially in areas with smaller sample sizes. Social science researchers have increasingly employed small area estimation to provide localised estimates of population characteristics from surveys. We explore how to extend this approach within the context of deep and persistent disadvantage in Australia. We find that because of the unique circumstances of the Australian population distribution, direct estimates of disadvantage have substantial variation, but by applying small area estimation, there are significant improvements in precision of estimates.     

Sustainable development of small‐ and medium‐sized enterprises in the European Union: A taxonomy of circular economy practices

This paper focuses on the implementation of circular economy (CE) practices in small‐ and medium‐sized firms in all 28 European Union (EU) countries. The analyses take into account the hierarchical nature of the collected data as firms are nested within EU countries, that is, the heterogeneity between different types of firms and countries according to practices and attitudes towards CE. The multilevel latent class model identifies groups of firms and groups of EU countries that are homogeneous in terms of CE, that is, how the homogeneous groups of small‐ and medium‐sized enterprises (SMEs) are distributed across the groups of EU countries. These results, together with the fact that firms with similar CE attitudes and practices have different demographic and business profiles across groups of countries, shed further light on the topic of green behavior in the EU with implications for businesses' environmental policies. Moreover, indications emerge that European policies favoring the implementation of CE practices should be targeted at least for subgroups of European countries, considering the different composition by typology of SMEs operating in their territories and that, at the same time, policies should be defined within each group of countries to account for the specific features of each of the four classes of SMEs.     

A comparison of family and nonfamily small firms in their approach to green innovation: A study of Italian companies in the agri‐food industry

Despite the growing scholars' attention toward green innovation, on the one hand, and family firms, on the other hand, there is still limited attention toward the intersection of these two streams of literature, because very few studies deal with green innovation in family firms. This paper aims at comparing family and nonfamily small firms in their approach to green innovation. To this aim, a multiple case studies methodology was used to understand whether and in which aspects family firms and nonfamily firms differ. In particular, a sample of 14 small enterprises (seven family and seven nonfamily firms) operating in the agri‐food industry and located in Italy was studied. Results suggest that family and nonfamily firms are similar with regard to green innovation characteristics, features of the green innovation process, faced challenges, and achieved outcomes. On the contrary, family firms differ from nonfamily firms in three key areas: firm's motivations, most relevant pressures, and green innovation view.     

Producing Localized Commodity Frontiers at the End of Cheap Nature: An Analysis of Eco‐scalar Carbon Fixes and their Consequences

There is no single ‘great’ commodity frontier whose exploitation under current socio‐technical conditions could fuel capital accumulation at the global scale. According to Jason Moore, this represents the ‘end of Cheap Nature’ and signals a terminal crisis for capitalism as we know it. In this article we complicate this assertion by showing how, in the context of global environmental governance frameworks of carbon control, a diverse range of actors situated at multiple scales are intensifying the use of cities and their hinterlands for the production/transgression of localized commodity frontiers. We draw on scholarship on uneven geographical development, state‐led restructuring and eco‐scalar fixes to present two case studies from different segments of the carbon cycle in the global South. The first case demonstrates how the introduction of waste‐to‐energy technology in Delhi facilitated the generation of ‘carbon credits’ while waste matter itself became a commodity. The second discusses attempts by the Brazilian state of Amazonas (Amazônia) aspiring to shift from rainforest exploitation to financialized conservation supported by the ‘green global city’ functions of metropolitan Manaus. These cases demonstrate that although the global carbon‐control regime may enable accumulation, implementation remains speculative, and localized commodity frontiers provoke social resistances that jeopardize their durability.
