The way urban solids relate to urban voids, the spatial relations of urban space itself and all other characteristics that define urban space are paramount in determining human distribution in any given community. This determines social relations that in turn reproduce spatial relations. This kind of process determines what sort of community and hence environment that is eventually generated. It is the intention of this paper to establish urban variables and hence urban patterns that promote human distribution, which in turn creates a sustainable community. A further intention is to establish a language that could be used to generate policies and design rules for such communities.

Urban parks are usually studied as discrete, green public open spaces. Less studied is how parks are geographically distributed from a ‘spatial logic’ point of view, i.e. how they ought to be geographically distributed across the urban landscape. This paper evaluates the degree to which normative principles about park distribution are in evidence from the standpoint of three spatial goals: proximity, diversity and social need. Using Phoenix and Chicago as case studies, it offers an empirical example of how park distribution can be shown to conform (or not) to one or more distributive patterns. Descriptive measures show that Phoenix parks do not conform to any of these three distributional principles, while Chicago parks do somewhat better. In both cities, land uses surrounding parks heavily favour residential uses. In Phoenix, single-family homes are prioritized, making spatial distribution based on proximity, diversity or social need difficult. A strategy for acquiring a better spatial logic, within existing realities and constraints, is suggested.

Urban parks are community assets, providing people places to play and rest. Access to parks in urban environments promotes social equity and improves quality of life for surrounding neighborhoods. In this context, social equity is related to accessibility, i.e. the possibility of walking or biking from home to a public park, giving people who do not have access to a variety of entertainment an option that is a public good. This paper examines the spatial distribution of urban parks in the city of Curitiba, Brazil, and how it relates to the socio-economic conditions of surrounding neighborhoods. Curitiba is known for its urban parks; however, no systematic study has been conducted to verify which neighborhoods enjoy park access within walking distance and what the socio-economic differences are between the better and worse served neighborhoods. In addition, we investigate if access to green open space has improved between the last two decennial census, a period marked by unprecedented socio-economic affluence in Brazil. Research questions, to be addressed using spatial analysis, focus on equitable distribution, and spatial evolution of parks and social equity. Variables include measurable walking distances from census tracts to parks, income data from the 2000 and 2010 Brazilian decennial censuses, and qualitative data of urban parks in Curitiba. Findings offer recommendations for future implementation of additional parks in Curitiba so that all areas of the city have adequate green open space and all citizens have equal access to recreation and leisure opportunities.

This paper examines the relationship between ethnic residential segregation and two components of the built environment: the geographic distribution of its elements and their spatial configuration (i.e., the spatial relations and visual access between those elements). This relationship is investigated through a case study of Arab-Jewish residential segregation in Jaffa. Statistical and structural analyses (Q-analysis) of this case show that the conjunction of elements having different meanings (symbolic, cultural, functional, etc.) with spatial and visual integration attributes provides varying conditions for the expansion of the Arab Jewish residential patterns, a process potentially affecting the geographic scale intensity of residential segregation. It was found, for example, that public land uses having relatively 'neutral' ethnic and symbolic meanings (e.g. commercial sites and parks) and spatially integrated with the surrounding urban environment tend to moderate residential segregation. Identification of the institutional character of the built environment—segregation/encounters in mixed ethnic areas—may contribute to a more socially oriented spatial policy.

Crime has long been thought to be intimately associated with the physical environment in which it occurs. Theoretical and empirical developments over the past 20 years demonstrate that this relationship is complex and varies substantially at different levels of spatial and temporal resolution. Research on the distribution of property crimes in time and space resonates with research on the target selection processes of offenders to suggest that crime is strongly related to aggregate elements of the perceived physical environment: nodes, paths, edges and an environmental backcloth. The relationship between crime and the physical environment is mediated through individual awareness and action spaces. This implies a series of research issues and crime control policies for future exploration.

In the past five years the numbers of enclosed neighbourhoods have significantly increased in South Africa. These are existing neighbourhoods that are closed off through gates and booms across the roads. Many of these neighbourhoods are fenced or walled off as well, with a limited number of controlled entrances/exits, manned by security guards in some cases. The roads within these neighbourhoods were previously, or still are public property and in most cases the local council is still responsible for public services to the community within the enclosed neighbourhoods. In this way public urban space is privatised, whether formally or informally. I will explore the distribution of enclosed neighbourhoods in South Africa on a national scale and within two metropolitan municipalities, viz., the cities of Johannesburg and Tshwane. Then I proceed to highlight the nature and impact of these neighbourhoods on the privatisation of public space and draw on a wide basis of empirical data obtained through a national survey and in-depth case studies. Finally I will conclude with examples of lessons learnt from South Africa and how these may relate to international experience and future research on gated communities.

We study the link between self-employment and some salient aspects of entrepreneurship – namely business creation and innovation – in urban and rural labour markets. In order to do so, we combine indi- vidual and firm-level data for Britain aggregated at the Travel-to-Work Area level. We find that a higher incidence of self-employment positively and strongly correlates with business creation and innovation in urban areas, but not in rural areas. We also document that more rural than urban workers become self- employed in areas with comparably poor labour market opportunities, although this heterogeneity is not evident when focussing on entrepreneurship. Finally, we show that the misalignment between self- employment and our proxies for entrepreneurship in rural areas disappears once we account for local labour market conditions. Our results suggest that self-employment, business creation and innovation are well lined-up in urban areas because they capture the same economic phenomenon – namely, gen- uine entrepreneurship. This is not the case for rural areas.

We generate a number of hypotheses about face-to-face groups using the energy distribution principle: the frequency of an event is inversely related to the amount of energy expended in that event. The principle predicts that (1) the size of groups will be inversely related to the frequency of their occurrence; (2) at any group size, the composition of social positions will be less heterogeneous than chance; and, (3) as group size increases, observed compositional homogeneity will decline at a slower rate than chance. We test these hypotheses using data on more than 100,000 naturally occurring, public, face-to-face groups gathered in sampling sweeps through two communities over a three-year period. The data support the hypotheses and yield interesting differences in the strength of sex and race heterogeneity. We discuss the findings as they relate to the general energy distribution principle and to other sociological perspectives.

(no abstract available) Introduction: There are significant differences in physical inactivity in various geographical areas and among demographic groups. Previous research suggests that walking is the most common form of physical activity; however, not all built environments support walking for recreational or transportation purposes. Objective: The purpose of this study was to assess the extent to which area-level factors, poverty rate and racial distribution, are associated with aspects of the street-scale environment (i.e. sidewalk walkability and physical disorder) using community audits.

Drawing on recent developments in field theory, this article analyzes the struggle for survival of São Paulo’s street vendors in the face of a massive eviction campaign. I conceive of street vending as a social field divided into two unequal categories—licensed street vendors and unlicensed street vendors—and show that responses to the campaign varied along group lines. Unlicensed peddlers either abandoned the field or drew on local networks to continue peddling under harsher conditions, whereas licensed street vendors relied on well-established ties to actors in the political field. After these ties proved ineffective, licensed street vendors survived thanks to the intervention of a non-governmental organization (NGO) that activated the judicial field and mobilized the legal capital vested in the licenses. The linkage role performed by this actor with cross-field networks and expertise shows the strategic import of interfield relations, which replicate and reinforce the unequal distribution of assets inside the field.

By measuring twenty streetscape features and numerous other variables for 588 blocks in New York City, we were able to identify variables that explain pedestrian traffic volumes. We found significant positive correlations between three out of twenty streetscape features with pedestrian counts after controlling for density and other built environmental variables. The significant streetscape features are the proportion of windows on the street, the proportion of active street frontage, and the number of pieces of street furniture. This study provides guidance for streetscape projects that aim to create walkable streets and pedestrian-friendly environments.

Recent years have seen a resurgence of interest in the relation between networks and spatial context. This review examines critically a selection of the literature on how physical space affects the formation of social ties. Different aspects of this question have been a feature in network analysis, neighborhood research, geography, organizational science, architecture and design, and urban planning. Focusing primarily on work at the meso- and microlevels of analysis, we pay special attention to studies examining spatial processes in neighborhood and organizational contexts. We argue that spatial context plays a role in the formation of social ties through at least three mechanisms, spatial propinquity, spatial composition, and spatial configuration; that fully capturing the role of spatial context will require multiple disciplinary perspectives and both qualitative and quantitative research; and that both methodological and conceptual questions central to the role of space in networks remain to be answered. We conclude by identifying major challenges in this work and proposing areas for future research.

Situating itself in encounter and public space debates and borrowing from non‐representational theory approaches, this paper uses data from the authors' 2‐year Economic and Social Research Council research project to consider how local urban parks can work as sites of routine encounter, mixity, and place belonging. The paper explores how parks as green public spaces are important as sites of inclusive openness while the materiality of parks is a key dynamic in affective encounter processes. Parks can work as animators of social interactions, participatory practices, and place affinities across ethnic and cultural difference. The paper concludes that the concept of convivial encounter can be extended to incorporate the concept of elective practices – choosing to be in shared public space can generate connective sensibilities that are not necessarily contingent on exchange. In using parks as a lens to examine localities and diversity, the paper critically reflects on research practices for understanding and describing heterogeneous formations of multiculture and outlines how the project's research design and the fieldwork methods sought to carefully and appropriately undertake research with complexly different places and populations.

Preferences for urban spaces were studied as a function of spatial category and nine predictor variables: spaciousness, refuge, enclosure, coherence, legibility, complexity, mystery, typicality, and age. A non-metric factor analysis of the preference ratings yielded four categories of urban spaces: Open-Undefined, Well- Structured, Enclosed Settings, and Blocked Views. These categories are similar to the spatial categories proposed for natural environments by S. Kaplan (1979, Assessing Amenity Resource Values. USDA Forest Service General Technical Report RM-68), who stressed openness and spatial definition as bases for categorization. The Well-Structured category was best liked, with the other categories not very well liked and about equal in preference. Regression analyses revealed three variables as consistent predictors of preference. Coherence and complexity were positively related to preference, and age was negatively related. Overall, the results support the Kaplans' proposal that both spatial and non-spatial factors are important in categorizing environments and in explaining environmental preferences.

Spatial synergy, as defined in this paper, is composed of characteristics of physical-spatial organization of the city which support the actions and behaviour of people, particularly in public space (supportiveness). Spatial synergy concerns the relationship between ‘things and things’, while supportiveness concerns the relationship between ‘people and things’. In the context of the city, things are buildings, technical facilities and plantings; people are the inhabitants and other users. Spatial synergy is achieved through a specific way of arranging buildings, technical facilities and plantings to form open spaces (space segments or places). It is achieved through the way these are interrelated (‘relation and communication’) within the urban fabric. It is also achieved through the degree of accessibility of all such defined places within a settlement unit (‘universal distance’). The physical-spatial characteristics that support actions and behaviour in public spaces (supportive characteristics) are simultaneously those towards which urban design should be directed, if it is to fulfil its purpose. In this context the author emphasizes the viewpoint, in contrast to the tradition of the Modern Movement, that public space has to be the decisive component in creating and developing settlement units that are habitable in the true sense.

Through a case study based in Bristol, this article explores how the law of place' has transformed multiple heterogeneous city centre spaces into a single homogeneous and commodified privately owned retail site. Drawing on de Certeau, Lefebvre, and humanistic geographers including Tuan, the article explores how law facilitates spatial and temporal enclosure through conventional understandings of private property, relying on techniques of masterplanning, compulsory purchase, and stopping up highways. It suggests that the law of place draws on binary spatial and conceptual distinctions to apparently separate places from spaces, applying different legal rules either side of an often invisible boundary line. The article questions this legally facilitated spatial and conceptual enclosure, particularly as it restricts spatial practices within the public realm. It concludes by rejecting an urban 'right to roam' as insufficiently transformative, calling for a broader interpretation of Lefebvre 's 'right to the

The modern world is facing rapid urbanisation, increasing urban population, constant growth of cities and the construction of new neighbourhoods. Moreover, new neighbourhoods often lack the elements of identity in the context of the place and the people who live there. Therefore, it is necessary to construct these identities together with the physical and natural structure of place and the cultural identity of the people. The construction of spatial identities has been studied in two case studies of “new” neighbourhoods, Mađir (Banjaluka, Bosnia- Herzegovina) and Ilsvika (Trondheim, Norway), using a qualitative analysis method. The comparison makes use of a triangle model that includes three elements of identity construction as three points of analysis: a) spatial context, b) participation in processes of planning and construction and c) action in place. The two cultural contexts and two ways of constructing spatial identity in the new neighbourhoods studied show certain similarities and differences. The study points to the universal significance of this phenomenon and indicates that the process could be improved in each case by applying positive experiences from the other, with adaptation to the specific context. Considering the importance and interrelation of the three elements involved in construction of spatial identities, they should be harmonised in all stages of development.

Existing urban open space typologies within dense urban fabrics cannot meet society’s open space requirements in developing countries’ metropolitan cities, such as Istanbul. Because of high building densities, it is a challenging task to create new open spaces within urban cores. Developing new tools that work with the existing built environment is crucial to reveal ‘opportunity spaces’ that can act as breathing points within dense urban fabrics. In this research, a new model is developed to evaluate the 3D spatial enclosure of open spaces using basic geometrical properties and geographic information system (GIS) tools. As a case study, Istanbul’s changing spatial organization is analyzed using this model.
