Plant closures and taskforce responses:an analysis of the impact of and policy response to MG Rover in Birmingham

This paper explores the socio-economic impacts and associated policy responses to the collapse of MG Rover at Longbridge in Birmingham. Critically, it attempts to move beyond a ‘standard’ taskforce narrative that emphasizes the role of the regional response. While recognizing that significant policy ‘successes’ were indeed evident at the regional level in anticipating and responding to the crisis, a wider perspective is required that situates this taskforce response in (1) a fuller understanding of labour market precariousness (that in turn mitigates some of its policy ‘successes’), and (2) more local perspectives that highlight the local impacts of closure, the role of the neighbourhood level officials and the third sector in mediating these. Taking this broader perspective suggests that longer-term, workers face a precarious situation and the need for policies to create and sustain ‘good quality’ jobs remains paramount. Adding in more local perspectives, a key lesson from the Longbridge experience for dealing with closures more generally is that the public policy responses must be: multidimensional in that they transcend narrow sector-based concerns and addresses broader spatial impacts; inclusive in that they build on a broad coalition of economic and social stakeholders; and long-term in that they acknowledge that adaptation takes many years. If anything, the Birmingham Longbridge experience demonstrates the difficulty of achieving such responses in the context of crisis where action is imperative and deliberation a luxury.

A Variable Neighborhood Search Approach for Solving the Maximum Set Splitting Problem

This paper presents a Variable neighbourhood search (VNS) approach for solving the Maximum Set Splitting Problem (MSSP). The algorithm forms a system of neighborhoods based on changing the component for an increasing number of elements. An efficient local search procedure swaps the components of pairs of elements and yields a relatively short running time. Numerical experiments are performed on the instances known in the literature: minimum hitting set and Steiner triple systems. Computational results show that the proposed VNS achieves all optimal or best known solutions in short times. The experiments indicate that the VNS compares favorably with other methods previously used for solving the MSSP. ACM Computing Classification System (1998): I.2.8.

"Belonging” in the gentrified Golden Horn/Halic neighbourhoods of Istanbul

Mainstream gentrification research predominantly examines experiences and motivations of the middle-class gentrifier groups, while overlooking experiences of non-gentrifying groups including the impact of in situ local processes on gentrification itself. In this paper, I discuss gentrification, neighbourhood belonging and spatial distribution of class in Istanbul by examining patterns of belonging both of gentrifiers and non-gentrifying groups in historic neighbourhoods of the Golden Horn/Halic. I use multiple correspondence analysis (MCA), a methodology rarely used in gentrification research, to explore social and symbolic borders between these two groups. I show how gentrification leads to spatial clustering by creating exclusionary practices and eroding social cohesion, and illuminate divisions that are inscribed into the physical space of the neighbourhood.

Probabilistic topographic information visualisation

The focus of this thesis is the extension of topographic visualisation mappings to allow for the incorporation of uncertainty. Few visualisation algorithms in the literature are capable of mapping uncertain data with fewer able to represent observation uncertainties in visualisations. As such, modifications are made to NeuroScale, Locally Linear Embedding, Isomap and Laplacian Eigenmaps to incorporate uncertainty in the observation and visualisation spaces. The proposed mappings are then called Normally-distributed NeuroScale (N-NS), T-distributed NeuroScale (T-NS), Probabilistic LLE (PLLE), Probabilistic Isomap (PIso) and Probabilistic Weighted Neighbourhood Mapping (PWNM). These algorithms generate a probabilistic visualisation space with each latent visualised point transformed to a multivariate Gaussian or T-distribution, using a feed-forward RBF network. Two types of uncertainty are then characterised dependent on the data and mapping procedure. Data dependent uncertainty is the inherent observation uncertainty. Whereas, mapping uncertainty is defined by the Fisher Information of a visualised distribution. This indicates how well the data has been interpolated, offering a level of ‘surprise’ for each observation. These new probabilistic mappings are tested on three datasets of vectorial observations and three datasets of real world time series observations for anomaly detection. In order to visualise the time series data, a method for analysing observed signals and noise distributions, Residual Modelling, is introduced. The performance of the new algorithms on the tested datasets is compared qualitatively with the latent space generated by the Gaussian Process Latent Variable Model (GPLVM). A quantitative comparison using existing evaluation measures from the literature allows performance of each mapping function to be compared. Finally, the mapping uncertainty measure is combined with NeuroScale to build a deep learning classifier, the Cascading RBF. This new structure is tested on the MNist dataset achieving world record performance whilst avoiding the flaws seen in other Deep Learning Machines.

The capacity challenges of nonprofit, community-based organizations

This mixed method case study explored the capacity challenges of neighbourhood based community centres related to the areas of governance and leadership, program delivery, financial management and human resources. The study involved the examination of three community centres with multi-mandates (i.e., provide programs and services to individuals from pre-school to seniors in the areas of social, educational, recreational and health) and utilized three phases of data collection: 1) surveys with board members; 2) focus groups with all boards and staff; and 3) document review which examined pertinent organizational policies and procedures. Questions were aimed at gaining an understanding of some of the challenges faced by staff and administrators of neighbourhood based community centres, as there a gap in the research in this particular area. Research findings identified a number of related challenges facing non-profit organizations specifically in the areas of funding and staffing and how these challenges impact both day to day operations and longer term sustainability. More research is needed with nonprofit organizations that have these broader mandates and diverse operational challenges, hence greater capacity building challenges.

Building connections: political participation, social capital and the built environment in St. John's, Newfoundland

How does where we live affect how we live? Do characteristics of the built environment affect the civic and social lives of the people living there? This study examines these questions at the neighbourhood scale in the Canadian city of St. John's, Newfoundland. To do so, it combines data from a survey measuring respondents' social capital (defined as a combination of social participation, social trust, and civic participation) and a "built environment audit" that records the built characteristics of each respondent's neighbourhood. The study finds a significant, positive relationship between the walkability of a neighbourhood and the social capital of the people living there. This relationship is driven primarily by the effect of the built environment on voluntary participation and relationships with neighbours. The study also tests several methods of measuring walkability, and finds that an objective measure based on street geometry is the best predictor of social capital.

Tabagisme et défavorisation de quartier : étude exploratoire des expériences de stigmatisation chez les jeunes femmes

La prévalence du tabagisme a diminué dans les dernières décennies, mais les inégalités sociales reliées au tabagisme s’accentuent. Les stratégies de dénormalisation du tabagisme ont amené la stigmatisation des fumeurs. Le lien entre celle-ci et la défavorisation de quartier est mal compris. Cette étude qualitative a comparé les expériences de stigmatisation de quinze jeunes femmes fumeuses dont la moitié vivait dans des quartiers très défavorisés de Montréal et l’autre moitié résidait dans les quartiers les moins défavorisés. Dans ces derniers, stigmatiser les fumeurs fait partie de la norme. Le tabagisme est vu comme un symbole de pauvreté, entraînant l’utilisation de stratégies pour se distancer du stigma. Dans les quartiers défavorisés, les participantes rapportaient une stigmatisation basée sur le genre et elles tentaient d’y échapper en se cachant pour fumer. Les résultats mettent en lumière les effets non attendus des politiques anti-tabac et pourraient contribuer au développement de politiques plus équitables.

Can mean shift trackers perform better?

Many tracking algorithms have difficulties dealing with occlusions and background clutters, and consequently don't converge to an appropriate solution. Tracking based on the mean shift algorithm has shown robust performance in many circumstances but still fails e.g. when encountering dramatic intensity or colour changes in a pre-defined neighbourhood. In this paper, we present a robust tracking algorithm that integrates the advantages of mean shift tracking with those of tracking local invariant features. These features are integrated into the mean shift formulation so that tracking is performed based both on mean shift and feature probability distributions, coupled with an expectation maximisation scheme. Experimental results show robust tracking performance on a series of complicated real image sequences. © 2010 IEEE.

Bullying Involvement and Adolescent Substance Use: A Study of Multilevel Risk and Protective Factors

Bullying, frequent drunkenness, and frequent cannabis use are significant health-risk behaviours among youth. While many studies have demonstrated that bullying involvement may initiate a developmental pathway to both types of frequent substance use, there is a limited understanding of the connection between these behaviours. The presence of risk and protective factors within youths’ relationships and within their neighbourhoods may alter the associations between bullying involvement and both types of frequent substance use. A systemic approach is needed to assess the complex, social environments in which youth are embedded. The current thesis consists of two studies that examined the associations between bullying and both types of frequent substance use within the context of youths’ social environments. In Study 1, multilevel modeling was used to examine the associations between bullying and frequent substance use within the context of individual and neighbourhood risk factors. Our results indicated that the risk factors associated with both frequent drunkenness and frequent cannabis use exist at both levels, with neighbourhoods altering the association of individual risk factors. Moreover, bullying was a unique risk factor associated with both types of frequent substance use, whereas indirect associations were observed for victimization. Study 2 used a similar methodology to examine the association between bullying and both types of frequent substance use within the context of individual and neighbourhood protective factors. Once again, our results indicated that the protective factors associated with both types of frequent substance use exist at multiple levels, and that neighbourhoods altered the association of individual protective factors. Additionally, positive relationship characteristics interacted with the link between bullying and both types of frequent substance use. Together, these findings clarify the nature of the bullying-substance use link and emphasize the need to study adolescent development in context.

Clichy-Batignolles, Paris: a case of successful inner-city regeneration

The third issue of the column deals with the regeneration of inner-city rail station areas. The successful case of Gare Saint-Lazare in Paris is analyzed by Giulio Verdini, an architect and urban planner based in China and Paris. The quality of this recent project is evident at different levels: as an innovative experiment of planning with public consultation, as a new mixed-used neighbourhood organized around a beautiful park, as a collection of interesting contemporary buildings promoted through open architecture competitions. The memory of the old rails has been interpreted as an occasion for creating significant urban connections, and the city of Paris demonstrated again and again its rare capacity to regenerate itself. 内城火车站区域的更新历来不是件轻松的工作,这在1990年代以来诸多的欧洲城市中都已经得到印证.伦敦的国王十字车站和柏林的中央火车站区域都是著名的更新案例,此外还有鹿特丹和斯图加特中央火车站这些争议性的案例,它们都表明了这个更新过程有多么复杂而难料.其原因包括众多相互角力的私人及公众影响、改造带来的未知花费及收益,以及市民群体在其中扮演的越来越重要的角色.这个位于巴黎17区的克里希·巴蒂涅奥勒开发区更新项目同样如此.不过,随着项目的建造渐入佳境,我们愈发可以看出,它很可能会成为欧洲内城最成功的更新案例之一.这篇简要介绍的目的就是勾勒出这一成功案例背后的构思和动机,以展现这个理应矛盾重重而得到未充分利用的地段如何成为让巴黎西北区改头换面的良机.

Measuring the Diversity and the Integration of Film Production in Mercosur: A Social Network Analysis

Based on an original and comprehensive database of all feature fiction films produced in Mercosur between 2004 and 2012, the paper analyses whether the Mercosur film industry has evolved towards an integrated and culturally more diverse market. It provides a summary of policy opportunities in terms of integration and diversity, emphasizing the limiter role played by regional policies. It then shows that although the Mercosur film industry remains rather disintegrated, it tends to become more integrated and culturally more diverse. From a methodological point of view, the combination of Social Network Analysis and the Stirling Model opens up interesting research tracks to analyse creative industries in terms of their market integration and their cultural diversity.

The European Union Foreign Policy in the Caucasus and Central Asia: The Limitations of the Opening towards the East

This article intends to study the evolution of the European Union foreign policy in the Southern Caucasus and Central Area throughout the Post-Cold War era. The aim is to analyze Brussels’ fundamental interests and limitations in the area, the strategies it has implemented in the last few years, and the extent to which the EU has been able to undermine the regional hegemons’ traditional supremacy. As will be highlighted, the Community’s chronic weaknesses, the local determination to preserve sovereignty and an increasing international geopolitical competition undermine any European aspiration to become a pre-eminent actor at the heart of the Eurasian continent in the near future.

Late-career international migration and reproductive work. A comparison between Peruvian and Ukrainian women in the Southern Europe

Research on the relationship between reproductive work and women´s life trajectories including the experience of labour migration has mainly focused on the case of relatively young mothers who leave behind, or later re-join, their children. While it is true that most women migrate at a younger age, there are a significant number of cases of men and women who move abroad for labour purposes at a more advanced stage, undertaking a late-career migration. This is still an under-estimated and under-researched sub-field that uncovers a varied range of issues, including the global organization of reproductive work and the employment of migrant women as domestic workers late in their lives. By pooling the findings of two qualitative studies, this article focuses on Peruvian and Ukrainian women who seek employment in Spain and Italy when they are well into their forties, or older. A commonality the two groups of women share is that, independently of their level of education and professional experience, more often than not they end up as domestic and care workers. The article initially discusses the reasons for late-career female migration, taking into consideration the structural and personal determinants that have affected Peruvian and Ukrainian women’s careers in their countries of origin and settlement. After this, the focus is set on the characteristics of domestic employment at later life, on the impact on their current lives, including the transnational family organization, and on future labour and retirement prospects. Apart from an evaluation of objective working and living conditions, we discuss women’s personal impressions of being domestic workers in the context of their occupational experiences and family commitments. In this regard, women report varying levels of personal and professional satisfaction, as well as different patterns of continuity-discontinuity in their work and family lives, and of optimism towards the future. Divergences could be, to some extent, explained by the effect of migrants´ transnational social practices and policies of states.

Perspectives on gender, migration and transnational work: joint work of social reproduction and care in Southern Europe

This paper presents the "state of the art" and some of the main issues discussed in relation to the topic of transnational migration and reproductive work in southern Europe. We start doing a genealogy of the complex theoretical development leading to the consolidation of the research program, linking consideration of gender with transnational migration and transformation of work and ways of survival, thus making the production aspects as reproductive, in a context of globalization. The analysis of the process of multiscale reconfiguration of social reproduction and care, with particular attention to its present global dimension is presented, pointing to the turning point of this line of research that would have taken place with the beginning of this century, with the rise notions such as "global care chains" (Hochschild, 2001), or "care drain" (Ehrenreich and Hochschild, 2013). Also, the role of this new agency, now composed in many cases women who migrate to other countries or continents, precisely to address these reproductive activities, is recognized. Finally, reference is made to some of the new conceptual and theoretical developments in this area.

Análisis de preferencias del paisaje urbano entre barrios compactos y barrios postindustriales en Vitoria-Gasteiz. Implicaciones en la planificación urbana

Las características urbanísticas de las expansiones urbanas postindustriales desarrolladas en las últimas décadas en numerosas ciudades españolas presentan diferencias notables con las de barrios centrales y pericentrales más compactos preexistentes. Con el fin de estudiar cómo son percibidas por los ciudadanos de Vitoria-Gasteiz dichas diferencias urbanísticas, se realizaron 250 encuestas a residentes en los barrios compactos de la ciudad sobre sus preferencias entre el paisaje urbano de su barrio y el de los barrios postindustriales. Se observó que la gran mayoría de los encuestados prefirieron su compacto barrio en aspectos de sociabilidad, accesibilidad a servicios y bienestar global. Los resultados obtenidos se contrastaron con los de un estudio previo en el que una encuesta similar fue realizada a residentes en un barrio postindustrial. Se discuten las implicaciones de los resultados para desarrollar una práctica urbanística más sostenible y que integre la percepción de los usuarios de la ciudad.
