Throughout the urban development process over the last seven decades in Tehran, the capital city of Iran, many self-generated neighbourhoods have developed in which the majority of the residents are low-income families. On one hand, the main spatial attribute of these deprived neighbourhoods is spatial isolation from the surrounding, more affluent areas, which is accompanied by inadequate urban infrastructure and a lack of accessibility and permeability. On the other hand, the Tehran City Revitalisation Organisation - the governmental sector which is in charge of the deprived areas - is incapable of conducting urban regenerations without investment from the private sector, and is seeking methods to create ‘socio-economic stimulant zones’ to attract private sector participation in regeneration programmes. In this regard, this research investigates the notion of ‘spatial isolation’ which in return causes socio-economic isolation as highlighted in the literature. The research suggests that in order to develop feasible regeneration programmes, which can meet the interest of both people and government, and release the deprived area from isolation both spatially and socio-economically, the regeneration plans should focus on public open space developments as ‘socio-economic stimulant zones’. With regard to this idea, the research highlights the street as a ‘social arena’ – not arteries or thoroughfares – as the type of public open space in which its development could not only release the deprived areas from spatial isolation, but could also direct more pedestrian movement to and through the deprived neighbourhoods, making more opportunities for the creation of socio-economic interactions. In this respect, the theory of ‘natural movement’ and theories and literature of ‘integrated public open spaces’ form the theoretical framework of the research to support this idea. For further investigation, two case studies, one as the deprived area and one as the control area, have been chosen, and the spatial pattern of the city and the two cases have been analysed in regard to the notion of ‘spatial isolation’ through Space Syntax using Depthmap software and GIS. Also, the correlation between the distribution pattern of commercial land uses and syntactic measures across the city of Tehran is investigated to identify the potential streets in which to create commercial opportunities. Afterwards, in order to study the street life and the variety of activities the streets can afford, a few locally integrated streets in the deprived case have been chosen. At this stage, nineteen behaviours have been observed and classified in five major classes including the necessary, social, optional, hazardous, and occasional activities, and the correlation with syntactic measures are studied. Moreover, the methods of developing a route filtering system and a transformability index for identifying the most suitable streets for the creation of a pedestrian friendly network are discussed, using an example of a deprived area, integrating it with the surrounding urban fabric to create the ‘socio-economic stimulant zones’. The results show that by identifying the underlying spatial pattern of the urban fabric, it is possible to release the deprived areas from its spatial isolation through developing a street network without causing urban fragmentation. This approach could also form a cost-effective basis for developing a pedestrian friendly street network as one of the ‘socio-economic stimulant zones’, which the Tehran City Revitalisation Organisation is looking for; the type of streets that not only support the necessary activities and transportation, but could also facilitate socio-economic interaction.

Concern for children’s safety and protection has become a global issue and has evoked considerable debate since the publication of the United Nations’ widely ratified Convention on the Rights of the Child (UNCRC) in 1989. A dominant theme within this charter and within the African Charter on the Rights and Welfare of the Child (1990) is the recognition that children are individuals with rights that need to be respected and protected. More specifically, Article 32 of the UNCRC states that children should be protected from ‘economic exploitation and from performing any work that is likely to be hazardous or to interfere with the child's education, or to be harmful to the child's health or physical, mental, spiritual, moral or social development’. Nigeria has signed and ratified both the UNCRC and the African Charter and has committed itself to ensuring the welfare and protection of its children. This thesis examines children’s work experiences and their interpretations of these against the backdrop of the provisions of the UNCRC and the African charter. The study sets out to explore the meanings of work for itinerant street vending children and young people in Enugu, Nigeria and is based on a combined ethnographic methodology of participant observation and semi-structured interviews with 24 child vendors in marketplaces over a period of six months. It will be argued that contemporary ideas about children’s work are framed by Euro-centric, adult perceptions and definitions of what they think working children are doing, and that the imposition of Western constructions of childhood does not reflect the lived realities of children. Discussions with children revealed, among other things, a contradiction and ambivalence in their understandings of work in relation to vending and an interplay of complex environmental, cultural and poverty factors. In children’s views, taking responsibilities in activities that add positive values to their personal development and to the continued survival of their families was part of their childhood. Whilst street based observations of the markets revealed some fundamental dangers and problems with street vending, especially the reality of physical, social and emotional abuse, these young children have developed robust coping mechanisms and social networks which reflect a blend of definitional adjustments, rationalisation and social bonding and which reveal inadequacies in the enforcement of child protection policies. The tension between these risks and the importance of vending in the lives of the children is discussed. The role and type of work are further examined against dominant cultural values and socio economic realities in Nigeria in an attempt to fully explain the phenomenon of children’s work in this milieu. This study concludes that children’s participation in vending, while at times both ‘hazardous’ and ‘harmful’, is a fact of life and a way of life for children growing up in Nigeria, an integral part of their childhood activity, and a realistic preparation for their future lives and careers. It is argued that this raises important challenges not only to the children’s rights agenda, but also to social welfare agencies which seek to provide support to children and young people in developing countries such as Nigeria.

This thesis explores the practices, motivations, and sensorial experiences of Montreal’s metro buskers. By examining the lived experiences of ‘street’ performers in the stations and connecting passageways of Montreal’s underground transit system, I consider what it ‘means’ to be a metro busker from the perspective of the performers. Informed by my ethnographic fieldwork among metro buskers, I detail their performance practices, ‘staging’ strategies, uses of technology, bodily dispositions, and subjective perceptions in relation to the public, each other and the spaces of performance. In the process, I make visible—and audible—the variable and improvisational nature of busking practices, and how these are constituted in relation to the physical features of the performance sites. More broadly, I explore the co-productive relations between body and space, the sensorial experiences and spatial practices of everyday urban life, and the potential for moments of micro-social encounter and appropriations of spaces that are not designed to foster conviviality and creative engagement. I locate ‘the busker’ within these questions not as a fixed identity or subject-position but as an embodied assemblage-act that is socially and materially situated and subjectively enacted through highly variable practices, perceptions and experiences. In detailing the moments of social encounter precipitated by metro buskers, I propose understanding busking as a form of Gift-performance that finds certain parallels in sensory ethnographic videography. I show how the influences of diverse participants—human and material—on the filming, editing, and distribution processes changed the course of the audio-visual production in this research. Finally, I introduce a notion of ‘expanded trajectory’ that links performer and space, researcher and participant, and may enable new acts of encounter and exchange, new processes of social and material circulation, new forms of Gift. / Graduate / 2018-05-15 / 0326 / nick.wees@gmail.com

INTRODUCTION: Street medicine programs utilize a nontraditional healthcare model to provide care to populations experiencing homelessness. Through street medicine programs, clinicians take to the streets to offer services to individuals who are living unsheltered. Many street medicine programs offer health professional students the opportunity to volunteer and provide care to this vulnerable population. AIM: This exploratory study aimed to answer the following question: what influence does volunteering with a street medicine program have on the career trajectories of student volunteers who ultimately choose to work with medically underserved populations (MUPs)? METHODS: This study used an exploratory mixed methods approach to answering the research question. The core ideas that emerged from the qualitative data collected from street medicine student volunteers were used to inform the development of a web-based survey administered to a broader, national sample of street medicine student volunteers. The survey included closed- and opened- ended questions, as well as demographic questions. The Health Professionals’ Attitude Towards the Homeless Inventory (HPATHI; Buck et al., 2005) questionnaire was embedded into the survey to measure students’ attitudes towards the population experiencing homelessness before and after volunteering with a street medicine program. RESULTS: The results suggested that 15 (65.22%) of the 23 participants who completed the web-based survey reported that volunteering with a street medicine program influenced their decision to ultimately work with MUPs. Of the 19 participants who provided qualitative feedback, 7 (36.84%) mentioned that their decision to work with MUPs was influenced by their increased exposure and awareness to the barriers and needs of MUPs while volunteering with a street medicine program. Additionally, 6 (31.58%) participants mentioned that their previous decision to work with MUPs was reinforced while volunteering with a street medicine program. CONCLUSION: Volunteering with a street medicine program appears to help motivate students to work with MUPs. Incorporating opportunities to volunteer with a street medicine program into current health professional school curriculum has the potential to impact a greater network of students, as well as influence decisions regarding the students’ careers.

City streets are the most widely distributed and heavily trafficked urban public spaces. As cities strive to improve livability in the built environment, it is important for planners and designers to have a concise understanding of what contributes to quality streetscapes. The proportions and scale of buildings and trees, which define the three-dimensional extents of streetscapes, provide enduring, foundational skeletons. This thesis investigates how characteristics of such streetscape skeletons can be quantified and tested for appeal among human users. The first of two journal-style papers identifies a concise set of skeleton variables that urban design theorists have described as influential to streetscape appeal. It offers an automated GIS-based method for identifying and cataloging these skeleton variables, which are practical to measure using widely available spatial data. Such an approach allows measurement of tens of thousands of street segments precisely and efficiently, a dramatically larger sample than can be feasibly collected using the existing auditing techniques of planners and researchers. Further, this paper examines clustering patterns among skeleton variables for street segments throughout Boston, New York, and Baltimore, identifying four streetscape skeleton types that describe a ranking of enclosure from surrounding buildings--upright, compact, porous, and open. The types are identifiable in all three cities, demonstrating regional consistency in streetscape design. Moreover, the types are poorly associated with roadway functional classifications--arterial, collector, and local--indicating that streetscapes are a distinct component of street design and must receive separate planning and design attention. The second paper assesses relationships between skeleton variables and crowdsourced judgments of streetscape visual appeal throughout New York City. Regression modeling indicates that streetscapes with greater tree canopy coverage, lined by a greater number of buildings, and with more upright cross-sections, are more visually appealing. Building and tree canopy geometry accounts for more than 40% of variability in perceived safety, which is used as an indicator of appeal. While unmeasured design details undoubtedly influence overall streetscape appeal, basic skeletal geometry may contribute important baseline conditions for appealing streetscapes that are enduring and can meet a broad variety of needs.

The municipal social services under the Social Services Act is responsible for the municipality’s citizens, but is at risk because of the situation in social services as social secretaries choose professions other than the exercise of authority. Social service work may be compromised on the basis that there will be a heavy workload for those social secretaries that stays when there are not enough resources. How social secretaries experience control in their work affects the way to trade and manage their work situation and the perceived control may be a discretion. The purpose of this study was to investigate how social secretaries perceive their work situation. The study was conducted based on a qualitative method and consisted of interviews of five social secretaries that all work in the same municipality. It was revealed from the qualitative content analysis that the social secretary job situation may seem complicated and the social secretaries tend to ”end up trapped” on the basis o fits position between the organization and the client. The conclusion of the study show that social secretaries work situation is characterized by frustration, both from the client and from the social secretaries own frustration to feel limited in their role as street-level bureaucrat. The framework constituting the discretion consists of organizational and social factors that the social secretaries needed to relate to. The discretion was perceived limited but constituted mainly a security in the complex work. / Kommunens socialtjänst har enligt socialtjänstlagen det yttersta ansvaret för kommunens medborgare, men detta riskeras på grund av den situation som råder inom socialtjänsten då socialsekreterare väljer andra yrken än myndighetsutövningen. Socialtjänstens arbete kan äventyras utifrån att det blir en hög arbetsbelastning för de socialsekreterare som arbetar kvar och att resurserna inte räcker till. Hur socialsekreterare upplever kontrollen i arbetet påverkar deras sätt att handla och hantera sin arbetssituation och den upplevda kontrollen kan utgöras av ett handlingsutrymme. Syftet med studien var att undersöka hur socialsekreterare upplever sin arbetssituation. Studien genomfördes utifrån en kvalitativ metod och bestod av intervjuer av fem socialsekreterare som arbetar inom samma kommun. Det framkom av den kvalitativa innehållsanalysen att socialsekreterares arbetssituation kan upplevas som komplicerad och att socialsekreterare tenderar att ”hamna i kläm” utifrån sin position mellan organisationen och klienten. Slutsatsen av studien visar att socialsekreterarnas arbetssituation präglas av frustration, dels från klient och dels från socialsekreterarnas egen frustration i att känna sig begränsad i sin roll som gräsrotsbyråkrat. Ramen som utgör handlingsutrymmet består av organisatoriska och sociala faktorer som socialsekreterarna behövde förhålla sig till i arbetet. Handlingsutrymmet upplevdes begränsat men utgjorde till största del en trygghet i det komplicerade arbetet.

This thesis explores the design of a food service space in an historic building in Richmond, Virginia near the campus of Virginia Commonwealth University. It is a result of retrofitting an awkward 1850s building by transforming it through the modern concept of a fast casual style restaurant, based in whole ingredients. The thesis is about the process of designing to rebalance the relationship between food and consumer in a modern era.

The aim and scope of my thesis is to examine the process of playwrights directing their own work, using the production of my play Obscura as an example of personal research, as well as examples of other dramatists. I will examine the advantages and disadvantages that playwrights face when directing their own work. I will compare several methods to my own production of Obscura. I wrote the play in the Spring of 2005 which culminated in a reading in April, followed by a workshop production in the Fall of 2005 in the Newdick Theater at Shafer Street Playhouse.
