In planning for future electricity supplies certain issues will need to be considered such as increased energy usage, urbanisation, reduction in personnel, global warming and the conservation of natural resources. As the result, some countries have investigated the transformation of their existing power grid to the so-called Smart Grid. The Smart Grid has three main characteristics which are, to some degree, antagonistic. These characteristics are the provision of good power quality, energy cost reduction and improvement in the reliability of the grid. The need to ensure that they can be accomplished together demands much richer Information and Communications Technology (ICT) networks than the current systems available. In this research we have identified the gap in the current proposals for the ICT of the power grid. We have designed and developed an ICT architecture for the neighbourhood sub-Grid level of the electrical network, where monitoring at this level is very underdeveloped because most current grids are controlled centrally and the response of the neighbourhood area is not generally monitored or actively controlled. Our designed ICT architecture, which is based on established architectural principles, can incorporate data from heterogeneous sources. This layered architecture provides both the sensors that can directly measure the electrical activity of the network (e.g. voltage) and also the sensors that measure the environment (e.g. temperature) since these provide information that can be used to anticipate demand and improve control actions. Additionally, we have de-signed a visualisation tool as an interface for a grid operators to facilitate a better comprehension of the behaviour of the neighbourhood level of the Smart Grid. Since we have noticed that energy aware ICT is a prerequisite for an efficient Smart Grid, we have utilised two different approaches to tackle this issue. The first approach was to utilise a cluster-based communication technique for the second layer of the architecture, which comprises Wireless Sensor Networks, where energy limitation is the major problem. Accordingly, we have analysed the energy-aware topology for wireless sensor networks embedded in the mentioned layer. We provide evidence that the proposed topology will bring energy efficiency to the communication network of the Smart Grid. The second approach was to develop a data reduction algorithm to reduce the volume of data prior to data transmission. We demonstrated that our developed data reduction is suitable for Smart Grid applications which can keep the integrity and quality of data. Finally, the work presented in this thesis is based on a real project that is being implemented in the medium voltage power network of the University of Manchester where power grid instrumentation, real data and professionals in the field are available. Since the project is long-term and the environmental sensor networks in particular are not currently installed we have evaluated some of our predictions via simulation. However, where the instrumentation was available, we were able to compare our predictions and our simulations with actual experimental results.

Most studies of 'cohesion' between urban residents focus separately on either social network structure or ideations with very little attention given to the intersection between spatial, structural and ideational dimensions of networks. This is problematic on two levels: firstly because attitudes and practices are formed in the context of personal social networks; and secondly because social interactions between residents are physically embodied and therefore spatially constrained. This thesis explores empirically the relationship between spatial cohesion (the extent to which a network is geographically localised or dispersed), structural cohesion (the extent to which a network is tight-knit or fragmented) and ideational cohesion (the extent to which residents have similar attitudes and practices). The social networks, attitudes and practices of white-British residents living in deprived urban localities of North Manchester are studied (survey, n=409; interview, n=53). Variances in forms of cohesion were found to have consequences for residents and localities. At the individual level, the spatial and structural shape of a resident's network was linked to their attitudes and behaviours. Attitudes and practices were 'framed' in the context of personal network structure exhibited through a set of resident 'roles'. This matters for urban cohesion because a person's social network structure influenced whether they liked their neighbourhood, trusted other residents, felt a sense of community or had found jobs through contacts. Previous studies have argued that contemporary urban networks have become fluid, dynamic and spatially dispersed. Yet this research found that although some people had networks that were geographically spread, most resident networks were made of localised, tight-knit, stable, long-term relations. Moreover, people with these cohesive, localised networks framed their experiences of urban cohesion differently to those with geographically spread and/or disconnected social networks. Particularly because the attitudes and practices of residents with localised, cohesive networks were very often habitual and socially reproduced. Social networks focus people's activities in such a way that not only constrains or enables current attitudes and practices but can also affect an individual's ability to change their future behaviour. At the locality level, the type of 'deprived' locality seemed to influence network structure. The structural, spatial and ideational distribution of cohesion at locality level provided neighbourhoods with different portfolios of social capital. Qualitative differences were observed between homogeneous-deprived (very low income, white areas) and socially mixed-deprived (white deprived areas with some class/ethnic mix) localities. People living in deprived-homogenous localities concentrated their networks within the local area and had few ties to residents of bordering areas, a sign of social distance. Conversely, residents of socially mixed-deprived localities had more potential to bridge ties to other neighbourhoods because their networks were not overly focused within the local area. Given that attitudes and practices are framed in the context of social network structure, it was argued that residents of deprived-homogeneous and socially mixed-deprived areas may experience and interpret urban cohesion differently and this has implications for universal policies of cohesion in deprived neighbourhoods. The thesis illustrates the interplay between spatial, structural and ideational forms of cohesion and highlights consequences for individual action and the generation of neighbourhood social capital. The originality of analysis and data synthesis are used to advance a relational and contextualised theory of urban cohesion and contribute to wider academic and policy debates on urban social networks and neighbourhood deprivation.

This research is a small part of a bigger field of research made before by other authorsregarding the humans in the urban public space. It has a small context compared to otherstudies, but a big impact inside the community. It aims at finding answers to questions thatother researchers asked before, but under different circumstances and they displayed them through different ways such as documentary films (The social life of small urban spaces 1980, How to live in a city 1964).After experiencing the city life of Malmö and some questions have been raised, the concept of resilience intersected with the interest of social public life in a neighbourhood. In order to have the theoretical framework to answer the research question, the thesis follows a literature review, where the concepts of resilience, urban resilience, resilient urban design and social resilience have been explored.Next, after exploring the city of Malmö, some case studies have been chosen and studiedthrough direct observation in different months starting with March and various times of theday. In the methodological approach section the methods are explained as well as a detailed presentation of the biggest tool used for this research: observational drawing. The tools used for the observation are field notes, observational drawings and photographs. The cases are spread throughout the city and are located in neighbourhoods with different urban tissues. The results reveal all the observational drawings made during the field visits and the field notes written. They show how people use the spaces in all three case studies depending on the weather or other external factors.The discussion reveals the complexity of the relation between concepts and the empiricaldata, following the initial aim of the research throughout the discussion. This thesiscontributes with important outcomes to the field of urban studies creating awareness about the urban context and its influence on people. The findings of this study show a diversity and creativity of users in using the public space.

This thesis investigates the myriad of responses and complex relationships residents have to the stigma attached to their neighbourhood, one categorised by the police as socially vulnerable (Nationella operativa avdelningen 2019). This research explores the narrative of place to diffuse some complexity around the multidimensional positions people have to stigma and stigmatising imagery of place. Drawing on qualitative interview material, with past and present residents in Hisings Backa, this thesis explores the narrative of stigmatisation from experiential and temporal perspectives of understanding the place of Hisings Backa. Using a feminist approach, the research highlights the importance of understanding everyday experiences of place and space in the context of locating the wider effects of place stigma.

The project includes a concept for the renewal of the urban situation of Place Lalla Yeddouna in Fez, Morocco, along side with the design of an Artisan's House. Suitable local materials and techniques has been used to create adequate, interesting and sensible rooms. The building by the square will allow the local artisans to work, exhibit, study and teach.

Cette thèse propose une analyse croisée des politiques d’aménagement et de transport au sein de la ville de Freiburg (Allemagne). L’objectif est d’interroger l’évolution des pratiques de la fabrique urbaine et de saisir les multiples transformations des systèmes de mobilité au prisme du développement durable. La recherche se fonde sur un double dispositif d’enquête quantitatif et qualitatif conduit au sein de la ville, et s’efforce de suivre les processus sur la moyenne durée afin de mieux éclairer les dynamiques d’actualité, tant du point de vue des conflictualités en jeu que des compromis pratiques. D’une part, l’examen des modalités de mise en œuvre des politiques de durabilité urbaine souligne l’existence d’espaces de négociations permanents entre acteurs concurrents. D’autre part, l’analyse affinée du système de transport et de la mobilité quotidienne des habitants des « quartiers durables » de Vauban et Rieselfeld, usuellement considérés comme des « modèles » en la matière, interroge au concret la portée d’une politique locale intégrée de développement urbain et de déplacements, en particulier quant à la place de l’automobile et ses alternatives. / This dissertation thesis presents a combined analysis of planning and transport policies in the city of Freiburg (Germany). The aim is to examine the evolving practices of the urban fabric and to grasp the multiple transformations of mobility systems from a sustainable development perspective. The research is based on quantitative and qualitative data from a survey conducted in the city. The research traces back the processes of transformation over the past few years in order to better understand current dynamics both from the point of view of the conflicts at stake and the compromises in practice. On the one hand, the study of the implementation modalities of urban sustainability policies highlights the existence of permanent negotiating spaces between competing actors. On the other hand, the refined analysis of the transport system and the daily mobility of the inhabitants of the "sustainable neighborhoods" of Vauban and Rieselfeld, which are usually considered as "models" in this matter, actually questions the scope of integrated local policies for urban development and mobility, in particular with regard to the place of the automobile and its alternatives.

The project explores the contribution of digital platforms to Social Sharing, a term used for the nonreciprocal, social aspect of Sharing, in the context of a local neighbourhood. Sharing is considered a way to create more sustainable ways of living and empower community engagement in cities.  The project used participatory design processes to create a conceptual prototype of a Sharing Platform. The platform proposes a digital whiteboard as a communication tool among residents and a board of Sharing actions modules to trigger residents' imagination on what can be shared. The outcomes of the process also entailed connections among stakeholders and the potential of new sharing initiatives. The project provides insights into methods for designing feasible solutions for the future using playfulness. It discusses how trust and access are established through digital platforms. Finally, it argues for the role of the latter as facilitators for social exchange in place.

This sandwich dissertation examines physical disorder as a type of ‘neighbourhood effect’ on education. My research takes a mixed-methods approach to understanding how physical disorder in areas surrounding schools might affect their educational outcomes, such as achievement, climate and discipline, over and above the demographic characteristics of their students. It also points to two possible mechanisms to therefore determine how these net effects might arise. This original contribution to the neighbourhood effects literature combines citywide, systematic data on physical disorder, neighbourhood demographics and school outcomes, with qualitative data on the views of stakeholders and repeated observations of select neighbourhoods. Through a quantitative and method-intensive paper, Chapter two discusses the procedures for collecting data on disorder, developing different scales of disorder, and how disorder relates to a variety of census measures and other neighbourhood and school measures. This research presents evidence that Systematic Social Observation (SSO) can provide a reliable and cost effective means of neighbourhood assessment. The results show that observed disorder is statistically related to neighbourhood socio-demographics, collective efficacy, and various academic outcomes. What is surprising, however, was that school exterior disorder had little to no explanatory power compared to observed disorder and graffiti in the face blocks surrounding schools. These findings highlight how beyond the recognized effects of socio-demographics, additional mechanisms in neighbourhoods, such as disorder and graffiti, can directly and indirectly influence school outcomes like achievement, discipline, and safety. My third chapter directly studies the impact of characteristics of neighbourhoods by examining the direct and additive effect(s) of observed disorder on academic achievement, discipline, and safety. Two sets of findings were reported. First, ordinary least squares (OLS) regression models showed that neighbourhood disorder but not school disorder was strongly associated with neighbourhood poverty. While the former effect was expected, the latter finding is interpreted as demonstrating how institutional processes in education can detach school physical plants from their immediate surroundings. Second, net of neighbourhood poverty and school size and type, higher levels of neighbourhood disorder were associated with lower school achievement, higher suspension rates, and larger proportions of students reporting to feel unsafe, though school disorder had far weaker effects. These findings are interpreted as demonstrating the power of neighbourhood disorder to trigger either student deviance or family self-selection processes, but also demonstrating how institutional processes can weaken the signalling power of disorder on school grounds and property. The fourth chapter provides an in-depth examination of two purported mechanisms to uncover the social processes that generated the broad relationships established in chapters 2 and 3. This research demonstrates that self-selection and reputational processes are likely generators of the net effects that were demonstrated in previous chapters. My qualitative evidence suggests that nearby disorder likely sends negative signals to would-be choosers of schools, creating (and perpetuating) long-lasting perceptions and reputations amongst aspiring, ambitious and achievement-oriented families. Schools with lots of nearby disorder are regarded to have deep-rooted problems, connected to their local populations and building conditions. As a result, aspiring families were recognized to self-select out of these disorderly schools, and re-locate elsewhere. This sandwich dissertation has found an intriguing pattern of effects and non-effects of disorder on schooling. It also highlights how neighbourhood disorder can send strong signals that ultimately shape school processes. Though many neighbourhood researchers have applied hypotheses of disorder to a variety of human capital outcomes there has been little recognition of disorder as a physical ‘neighbourhood effect’ on schooling. From this perspective, it is not only helpful to recognize that disorder in nearby areas seems to affect schooling, but that self-selection and reputation processes can explain how this specific neighbourhood effect might arise. Since a shortcoming of existing work is that neighbourhood attributes are measured primarily using census data, the contribution of this dissertation to sociology is that researchers are now better equipped methodologically to design their own standardized approaches and disorder scales that directly measure neighbourhood conditions. / Dissertation / Doctor of Philosophy (PhD)

The Stockholm Municipality has set inclusion at the core of its objectives for the city with its “Vision 2040: A Stockholm for Everyone” (Stockholm Stad, 2018). Acknowledging the divide between neighborhoods, the government has brought forward social sustainability as a key component to improve the fast-growing city. This research focuses on three of the most stigmatized neighborhoods of Stockholm: Rinkeby, Tensta, and Husby, where residents are predominantly of foreign background, to offer an alternative way of understanding inclusion. Specifically, this study looks into the public spaces at the center of these three neighborhoods in a comparative analysis of public life. The collaborative project presented here shows the importance of these centrums in supporting community life in the suburbs. Drawing from Setha Low’s research on public squares in Costa Rica, the following paragraphs suggest public space is not only produced by those who envision it, but also constructed by those who use it, through daily processes, behaviors, and habits. These observed patterns carry significance as they forge the character of a place, and address practices and emotions within a collective identity. The thesis puts emphasis on the dynamic nature of public space, the relationship between morphology and use, and the potential neighborhood centers have for becoming hubs of inclusion.

Kriminologisk forskning har sedan länge fokuserat på brottslighet och antisocialt beteende. Däremot har en mindre grupp individer genomgående uppgett att de aldrig ägnat sig åt antisocialt beteende och avstår således från brottslighet. Forskning inom detta område har varit jämförelsevis begränsad, men det har föreslagits att individens avhållande bygger på ett uteslutande från kamratgrupper som ett resultat av dennes oönskade egenskaper (t.ex. stark moraluppfattning). Andra menar istället att det är den starka moralen i sig som avhåller personer från att begå brott, vilket är en hypotes som testas i denna studie. Det görs genom att jämföra personer som uppger att de aldrig har begått brott, med personer som endast gjort det vid enstaka tillfällen. Detta i ljuset av variablerna moral, umgänge med brottsliga kamrater och tid som spenderas med vänner i ostrukturerade miljöer. Vidare undersöks eventuella könsskillnader. Med utgångspunkt i data från det longitudinella projektet Malmö Individual and Neighbourhood Developmental Study (MINDS) har logistiska regressioner använts för att undersöka direkta och medierande effekter. Resultaten visar att hög moral predicerar ett avhållande från brott utan en medierande effekt av brottsliga kamrater. Umgänge med brottsliga kamrater predicerar istället brottslighet hos ungdomarna, medan spenderad tid i ostrukturerade miljöer varken predicerar avhållande eller brottslighet. Könsskillnader som fanns indikerar på starkare moral hos kvinnor och att effekten av densamma hos män är beroende av umgänge. Moral bör därför inte ses som en uteslutande egenskap utan snarare som en viktig brottshämmande faktor. / The scientific focus of criminological research has since long been on criminal and antisocial behaviours. However, a group of individuals reporting that they have never engaged in delinquent behaviour (delinquency abstainers) have consistently been identified and until only recently not rendered much scientific interest. It has by some been proposed that delinquency abstention is a result of individuals being excluded from peer groups due to undesired characteristics (e.g. high sense of moral beliefs), although this notion is contested. Morality has by others instead been perceived as having a direct effect on abstention, which is the hypothesis tested in this study. It does so by comparing delinquency abstainers to low-frequency non-abstainers with regards to moral belief, delinquent peer association, and time spent unsupervised with peers, and furthermore examines the effects across gender. Logistic regressions were run to examine direct and mediating effects using data from the longitudinal project Malmö Individual and Neighbourhood Developmental Study (MINDS). Results indicate that strong moral beliefs have a direct effect on abstention and are not mediated by delinquent peer association. Associating with delinquent peers did in turn predict non-abstention but spending time unsupervised with peers did neither predict abstention nor delinquency. Some gender differences found points towards stronger morality amongst females and that the effect of morality for males depends on peer association. Morality should therefore not be perceived as an undesirable characteristic which excludes individuals from peer groups but rather an important factor in the inhibition of delinquency.
