This symposium creates and stimulates new dialogue and cross‐disciplinary exchange between planning theorists and geographers in researching the transfer of urban policy and planning models, ideas and techniques. The symposium challenges a restricted historical focus in much of the emerging geographical literature on urban policy mobilities by drawing on a rich tradition within planning history of exploring and documenting the trans‐urban travel of planning ideas and models over the last 150 years. It is argued that this longer‐term perspective is required to highlight important historical continuities and institutional legacies to contemporary urban policy circuits and pathways and to question what is particularly new, distinct and innovative about an intensification in the travel of urban ideas, plans and policies over the past decade — and the accompanying scholarly interest in them. The symposium also uses the emphasis on particular details and specific experiences within planning histories to foreground and develop approaches, particularly from recent geographical scholarship, that investigate the contingent and embodied practices and wider epistemic contexts that enable — or hinder — contemporary policy transfer.  相似文献

Union density in France has fallen to exceptionally low levels, yet unions are able to mobilise millions of supporters against government austerity measures. Some authors therefore argue that the union revitalisation literature overemphasises density over other power resources. The article first confirms the decline of density and the scale of the challenges unions face in organising in the face of restructuring and casualisation. Second, it is argued that unions have retained some policy influence by forming strategic alliances among themselves, although pressures for fragmentation remain strong. Third, unions' mobilising capacity indicates the need to find new ways of coordinating action at all levels. The article thus not only confirms the inadequacy of density alone as a measure of union vitality but also highlights the challenges, and some opportunities, facing unions in hostile economic conditions.  相似文献

More than 30 years after its premiere, Seinfeld continues its run as a seminally popular television show. On October 1, 2021, five-year streaming rights to the show were purchased by Netflix for $500 million. Set in New York City, where rent control laws have a long history, several episodes of the show consider the trials of apartment living, including shortages, tastes for discrimination by sellers, bribery, search costs, and quality degradation. Seinfeld also illustrates the informal process through which rent-controlled apartments are advertised (e.g., less advertising under rent control shortage). This paper argues that popular media can be used as an effective pedagogical tool in learning. This paper analyzes four episodes of Seinfeld to help students identify and differentiate the very real costs of rent control. The paper also guides students to appreciate the difficulty in crafting a policy that is free of unintended consequences.  相似文献

Research on management consultancy usually emphasizes the role and perspective of the consultants. Whilst important, consultants are only one element in a dynamic relationship involving both consultants and their clients. In much of the literature, the client is neglected, or is assumed to represent a distinct, immutable entity. In this paper, we argue that the client organisation is not uniform but is instead (like organisations generally) a more or less heterogeneous assemblage of actors, interests and inclinations involved in multiple and varied ways in consultancy projects. This paper draws upon three empirical cases and emphasizes three key aspects of clients in the context of consultancy projects: (a) client diversity, including, but not limited to diversity arising solely from (pre-)structured contact relations and interests; (b) processes of constructing ‘the client’ (including negotiation, conflict, and reconstruction) and the client identities which are thereby produced; and (c) the dynamics of client–consultant relations and how these influence the construction of multiple and perhaps contested client positions and identities.  相似文献

This paper takes as its starting point the fact that complex projects, interpreted as multiple dependent interactions between many stakeholders over time, challenge traditional procurement practices based on the serial purchase of discrete components. The paper examines how the procurement management of such projects – procuring complex performance – can be conducted. The paper utilises two contrasting case study examples of high-profile UK construction project procurement. The findings suggest that the choice of mechanisms or interfaces for the governance of upstream supply relationships critically relates to subsequent performance. The theoretical contribution is a fusion of procurement literature with the influential CoPS literature.  相似文献

This paper makes two important contributions to the literature on prediction intervals for firm specific inefficiency estimates in cross sectional SFA models. Firstly, the existing intervals in the literature do not correspond to the minimum width intervals and in this paper we discuss how to compute such intervals and how they either include or exclude zero as a lower bound depending on where the probability mass of the distribution of \( u_{i} |\varepsilon_{i} \) resides. This has useful implications for practitioners and policy makers, with greatest reductions in interval width for the most efficient firms. Secondly, we propose an ‘asymptotic’ approach to incorporating parameter uncertainty into prediction intervals for firm specific inefficiency (given that in practice model parameters have to be estimated) as an alternative to the ‘bagging’ procedure suggested in Simar and Wilson (Econom Rev 29(1):62–98, 2010). The approach is computationally much simpler than the bagging approach.  相似文献

The foundation upon which accounts of policy-motivated behaviorof Supreme Court justices are built consists of assumptionsabout the policy preferences of the justices. To date, mostscholars have assumed that the policy positions of Supreme Courtjustices remain consistent throughout the course of their careersand most measures of judicial ideology—such as Segal andCover scores—are time invariant. On its face, this assumptionis reasonable; Supreme Court justices serve with life tenureand are typically appointed after serving in other politicalor judicial roles. However, it is also possible that the worldviews,and thus the policy positions, of justices evolve through thecourse of their careers. In this article we use a Bayesian dynamicideal point model to investigate preference change on the USSupreme Court. The model allows for justices' ideal points tochange over time in a smooth fashion. We focus our attentionon the 16 justices who served for 10 or more terms and completedtheir service between the 1937 and 2003 terms. The results arestriking—14 of these 16 justices exhibit significant preferencechange. This has profound implications for the use of time-invariantpreference measures in applied work.  相似文献

After a long dormant period, Lower Sixth Avenue in New York has under gone a rapid revitalisation. We show that a simple search theoretic model with information spillovers can explain both the period of underuse and the rapid turnaround. The model reduces to a simple equation, which allows us to do comparative statics on the duration of vacancies. We show how the solution reacts to changes in market structure and changes in search technology. The model is suggestive of difficulties that may occur in many markets in which there are changes over time in the optimal use of resources.  相似文献

In this article we apply insights from ‘new mobilities’ approaches to understand the shifting sexual and gendered landscapes of major cities in the global North. The empirical context is the purported ‘demise’ of traditional gay villages in Toronto, Canada and Sydney, Australia, and the emergence of ‘LGBT neighbourhoods’ elsewhere in the inner city. We reinterpret the historical geography of twentieth century LGBT lives and the associated ‘rise and fall’ of gay enclaves through the lens of the ‘politics of mobility’. In this reading, it is apparent that multifaceted movements — migration, physical and social mobility, and motility — underpin the formation of gay enclaves and recent transformations in sexual and gendered landscapes. After the second world war, LGBT communities in the global North were embedded in specific historical geographies of mobility and we trace these in the Canadian and Australian contexts. The ‘great gay migration’ from the 1960s to the 1980s has been joined by new LGBT constellations of mobility in the 2000s, and these have imprinted upon the sexual and gendered landscapes of Toronto and Sydney.  相似文献

Understanding the effects of operational conditions and practices on productive efficiency can provide valuable economic and managerial insights. The conventional approach is to use a two-stage method where the efficiency estimates are regressed on contextual variables representing the operational conditions. The main problem of the two-stage approach is that it ignores the correlations between inputs and contextual variables. To address this shortcoming, we build on the recently developed regression interpretation of data envelopment analysis (DEA) to develop a new one-stage semi-nonparametric estimator that combines the nonparametric DEA-style frontier with a regression model of the contextual variables. The new method is referred to as stochastic semi-nonparametric envelopment of z variables data (StoNEZD). The StoNEZD estimator for the contextual variables is shown to be statistically consistent under less restrictive assumptions than those required by the two-stage DEA estimator. Further, the StoNEZD estimator is shown to be unbiased, asymptotically efficient, asymptotically normally distributed, and converge at the standard parametric rate of order n −1/2. Therefore, the conventional methods of statistical testing and confidence intervals apply for asymptotic inference. Finite sample performance of the proposed estimators is examined through Monte Carlo simulations.  相似文献
