This paper proposes an essentially new theory of urban space based on information theory and the laws of optics. The use of urban space is linked to the information field generated by surrounding surfaces, and on how easily the information can be received by pedestrians. Historical building exteriors usually present a piecewise concave, fractal aspect, which optimizes visual and acoustical signals that transmit information content. Successful urban spaces also offer tactile information from local structures meant for standing and sitting. The total information field in turn determines the optimal positioning of pedestrian paths and nodes. This complex interaction between human beings and the built environment, incredibly neglected in our times, explains why so many historical urban spaces provide an emotionally nourishing environment.

In the networked information and knowledge-based economy and society, the notions of ‘open’ and ‘openness’ are used in a variety of contexts; open source, open access, open economy, open government, open innovation – just to name a few. This paper aims at discussing openness and developing a taxonomy that may be used to analyse the concept of openness. Are there different qualities of openness? How are these qualities interrelated? What analytical tools may be used to understand openness? In this paper four qualities of openness recurrent in literature and debate are explored: accessibility, transparency, participation and sharing. To further analyse openness new institutional theory as interpreted by Williamson (2000) is used, encompassing four different institutional levels; cultural embeddedness, institutional environment, governance structure and resource allocations. At what institutional levels is openness supported and/or constrained? Accessibility as a quality of openness seems to have a particularly strong relation to the other qualities of openness, whereas the notions of sharing and collaborative economics seem to be the most complex and contested quality of openness in the knowledge-based economy. This research contributes to academia, policy and governance, as handling of challenges with regard to openness vs. closure in different contexts, territorial, institutional and/or organizational, demand not only a better understanding of the concept, but also tools for analysis.

This paper explores the question what kind of educational work can be done in attempts to reclaim or reinvigorate the public sphere. Through a discussion of the intersection of public sphere and public space, it engages with the work of Hannah Arendt in order to outline a conception of the public sphere as a space for civic action based on distance and the conservation of a degree strangeness rather than on commonality and common identity. The discussion of the educational work that can be done to support the public quality of common spaces and places focuses on three interpretations of the idea of public pedagogy: that of public pedagogy as a pedagogy for the public, that of public pedagogy as a pedagogy of the public and that of public pedagogy as the enactment of a concern for the public quality of human togetherness. The latter form of public pedagogy neither teaches nor erases the political by bringing it under a regime of learning, but rather opens up the possibility for forms of human togetherness through which freedom can appear, that is forms of human togetherness which contribute to the ‘becoming public’ of spaces and places.

This article explores the relationship between pavement cafés, street life and urban public social life. It argues that the licensing of public entertainment and the enforcement of liquor licences and rigid opening times have helped to undermine public social life in English cities. Attitudes which first gained ascendancy in the 1890s have remained dominant and, broadly speaking, unchanged. Nevertheless, there has been a recent and fairly rapid growth in wine bars, cafés and bistros in London and some other English cities. The paper explores whether these help to stimulate public social life. Reference is made to research in Holland and Denmark, and also recent experience in London and Manchester. The paper concludes that city policy makers should, in the short term at least, act to stimulate café culture. Some anti-social and behavioural problems might well require an element of control, and not all urban areas are suited to café culture. Yet in a technological age, café culture represents one of the few remaining opportunities for public sociability. Where it creates a nuisance, it could and should be controlled but this is not the same thing as exercising an all-persuasive moral control which has its roots in Victorian England.

A healthy built environment is one which connects citizens together to create a sense of community. These are influential determinants of good mental and physical health. This paper presents an overview of key research on how the built environment supports the development of community as part of creating and sustaining places for health and well-being. Formal public places such as town squares, plazas, parks and gardens cultivate community in numerous ways. Informal public places such as those in between buildings, on the street, at the train station and bus stop are also important for social encounters and interaction. Careful design of open space, neighbourhood streets and buildings can encourage human interaction as part of community creation. Evidence is presented here as a ‘Places Framework’ to illuminate the ways in which place strengthens community. The paper concludes by discussing and critically evaluating policy implications for urban planners and designers. Major gaps in the research are identified and suggestions made for future investigative work to strengthen the evidence for building healthy communities through built environment interventions.

The climate of a city influences the ways in which its outdoor spaces are used. Especially public spaces intended for use by pedestrians and cyclists, such as parks, squares, residential and shopping streets, and foot- and cycle-paths will be used and enjoyed more frequently when they have a comfortable and healthy climate. Due to a predicted global temperature rise, the climate is likely to be more uncomfortable in the Netherlands, especially in summer, when an increase in heat stress is expected. As the phenomenon of urban heat islands (UHI) aggravates heat stresses, the effects will be more severe in urban environments. Since the spatial characteristics of a city influence its climate, urban design can be deployed to mitigate the combined effects of climate change and UHI’s. This paper explores these effects and tries to provide tools for urban design and strategies for implementation. Consequently, the applicability of the design tools is tested in a design for two existing Dutch neighbourhoods.

Urban design scholars denounce the recent trend towards the privatization of US public space. Critics emphasize the negative consequences of privatized public space, tied to private ownership, an emphasis on consumption, leisure and security, a targeted audience, and controlled behaviour and design. Yet these key qualities of privatized public spaces have meaning only in the context of one's identity. The same qualities shape experiences of privatized public spaces that can be understood as constrained, as constraining or as a form of resistance, depending on one's gender, race, class and sexuality. This paper challenges the prevailing design critique by examining women's experience of privatized public spaces, drawing on interviews with 43 middle- class women and behavioural mapping in five privatized public spaces in Orange County, California. Recommendations address changes to research and practice to better reflect and accommodate diverse experiences of public space.

Australia is currently rolling out one of the most expensive and ambitious infrastructure projects in the nation’s history. The National Broadband Network is promoted as a catalyst for far-reaching changes in Australia’s economy, governmental service provision, society and culture. However, it is evident that desired dividends, such as greater social engagement, enhanced cultural awareness and increased civic and political participation, do not flow automatically from mere technical connection to the network. This article argues that public institutions play a vital role in redistributing technological capacity to enable emerging forms of social and cultural participation. In particular, we examine public libraries as significant but often overlooked sites in the evolving dynamic between digital technology, new cultural practices and social relations. Drawing on interviews and fieldwork across the public library network of the state of Queensland, we attend to the strategies and approaches libraries are adopting in response to a digital culture.

Discussions of public space and the public have become complicated in recent years. This article seeks to bring some clarity to these discussions by examining where participants in public space debates ‘locate’ the public – those spheres or realms where participants believe a public is constituted and where public interest is found. To identify the ways in which public space is conceptualized and located, we analyze the literature on public space, interviews with scholars actively involved in public space research, and interviews with participants in a series of public space controversies in the USA. We find that differing definitions of ‘the public’ that underlie these conceptualizations are rooted in strongly held political orientations and normative visions of democracy. But we also find that there is considerable overlap in how participants frame their understandings of publicity, and thus there is a basis for more thorough debate and even transformation of policy and practice.

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.

Epidemiology, sociology, and geography have been successful in re-establishing interest in the role of place in shaping health and health inequalities. However, some of the relevant empirical research has relied on rather conventional conceptions of space and place and focused on isolating the ‘‘independent’’ contribution of place-level and individual-level factors. This approach may have resulted in an underestimate of the contribution of ‘place’ to disease risk. In this paper we argue the case for extensive (quantitative) as well as intensive (qualitative) empirical, as well as theoretical, research on health variation that incorporates ‘relational’, views of space and place. Specifically, we argue that research in place and health should avoid the false dualism of context and composition by recognising that there is a mutually reinforcing and reciprocal relationship between people and place. We explore in the discussion how these theoretical perspectives are beginning to influence empirical research. We argue that these approaches to understanding how place relates to health are important in order to deliver effective, ‘contextually sensitive’ policy interventions. r 2007 Elsevier Ltd.

In this symposium, we explore how urban citizenship is about expressing, if not producing, difference, and how fragmentation of claims affects urban citizenship and right to the city movements with their universal, all-inclusive ideals. Investigating social movements, political participation and conflicting diversities in public space in Tel Aviv and Berlin, we see a trend towards a diversification of interests, a weakening of movements, and even a competition over rights and resources rather than a development of mutual support and solidarities among various groups on the pathway to a livable city. This tension, we argue, deserves attention. Radical urban scholarship and politics need to better understand the historical and place-specific contexts that structure the formation of citizenship claims and the courses that citizenship struggles take. Celebrations of urban citizenship as a more contextualized, community oriented, and bottom-up framework (in comparison to national citizenship) should therefore be complemented by a careful investigation of their fragmented and fragmenting practices.

This paper presents a model of, and method for benchmarking, the publicness of public space—termed here as the Star Model. The model is intended to be of value for comparative purposes (i.e. measuring the publicness of one place vis-a`-vis another); as an analytic measure of publicness to be compared with more subjective interpretations of publicness; and as a departure point for deeper investigations of why particular places are more/less public than they could/should be. The paper is in four main parts. The first part discusses and then conceptualizes the nature of ‘public’ space. The second considers publicness as a multi-dimensional concept, identifying and discussing five meta dimensions—ownership; control; civility; physical configuration; and animation. The third explains the model and the integration of these dimensions into a pictorial representation of a place’s publicness. The final part discusses the model’s value and suggests avenues for further development and research.

The World Gay Pride week convened in Rome in July 2000 at the same time the Catholic Church planned on celebrating its Holy Year Jubilee. Thousands of gays came together, and by the end of the week more than 200,000 marched through the streets of Rome's historical centre. This unique event provides an opportunity to examine the causal relationship of the gay movement acquiring a political identity of its own while the city of Rome was trying to assert a `proper' identity for its public spaces. Acting in solidarity for the first time since its formation, the gay movement drew attention to the difficulties in securing unrestricted access to Rome's public spaces. Conservative sectors of society challenged the right to demonstrate, as guaranteed in Italy's Constitution, which resulted in the delay of obtaining the necessary permit. On the one hand, this revealed the existence of sectors of society not yet willing to acknowledge gay rights or even discuss gay issues in public; on the other, it helped make clear that the process for building Rome's identity is governed by a specific political design. In particular, policies for the privatisation of urban space in conjunction with discriminatory planning processes in the city's historical centre, point to tourism as a powerful tool to control urban space. Resisting this spatial marginalization the gay movement has significantly widened the scope of its social and political action in order to contest prevailing practices and trends which are shaping the city.

Visiting urban parks regularly can provide significant physical and mental health benefits for children and teenagers, but these benefits are tempered by park quality, amenities, maintenance, and safety. Therefore, planning and public health scholars have developed instruments to measure park quality, but most of these tools require costly and time consuming field surveys and only a handful focus specifically on youth. We rectify these issues by developing the QUality INdex of Parks for Youth (QUINPY) based on a robust literature review of studies on young people’s park visitation habits and an extensive validation process by academic and professional experts. Importantly, the QUINPY relies on publicly available geospatial data to measure park quality. We then successfully pilot test the QUINPY in Denver and New York City. We believe that park agencies, planning consultants, researchers, and nonprofits aiming to assess park quality will find this tool useful. The QUINPY is particularly promising given the increasing amount of publicly available geospatial data and other recent advancements in geospatial science.

Problem, research strategy, and findings: Parks provide important physiological and psychological benefi ts to seniors, improving their quality of life; they are particularly important for low-income, inner-city seniors who lack access to open and green space. However, seniors do not often use parks partly because park design and programming are not responsive to their diverse needs and values. To identify what low-income, inner-city seniors seek and value in neighborhood parks, and to provide guidance to planners on how to better design senior-friendly parks, we conducted a literature review and held focus groups with 39 low-income, ethnically diverse seniors in an inner-city neighborhood in Los Angeles (CA). We asked these seniors about their preferences as well as the challenges and barriers they encounter in using neighborhood parks. Seniors report many impediments to park use; they are not provided appropriate programming that allows opportunities for socializing, safety, and security within the park and along access routes; opportunities for exercise and walking; and aesthetic and natural elements that provide contact with nature.Takeaway for practice: Park planners and designers should seek to incorporate senior voices in park design and programming in four ways by developing appropriate programming sensitive to diverse needs, accommodating the desire for �seniors-only� parks, promoting security and safety in the park and along access routes, and offering open and green space. We also fi nd the need for additional research on seniors from different racial and ethnic backgrounds.

Although a number of environmental and policy interventions to pro- mote physical activity are being widely used, there is sparse systematic information on the most effective approaches to guide population-wide interventions. Methods: We reviewed studies that addressed the following environmental and policy strat- egies to promote physical activity: community-scale urban design and land use policies and practices to increase physical activity; street-scale urban design and land use policies to increase physical activity; and transportation and travel policies and practices. These systematic reviews were based on the methods of the inde- pendent Task Force on Community Preventive Services. Exposure variables were classified according to the types of infrastructures/policies present in each study. Measures of physical activity behavior were used to assess effectiveness. Results: Two interventions were effective in promoting physical activity (community-scale and street-scale urban design and land use policies and practices). Additional information about applicability, other effects, and barriers to implementation are provided for these interventions. Evidence is insufficient to assess transportation policy and practices to promote physical activity. Conclusions: Because com- munity- and street-scale urban design and land-use policies and practices met the Community Guide criteria for being effective physical activity interventions, implementing these policies and practices at the community-level should be a priority of public health practitioners and community decision makers.

This thesis sets out to examine whether incorporating local independent or small regional chain retailers and restaurants along with national chain stores in new large scale open-air retail developments can help add to a “sense of place” in these projects and thus make them more successful. New retail developments of the past two decades, often called Lifestyle Centers, Urban Entertainment Centers, Town Centers or New Main Streets, attempt through design to create a “place.” However, unlike traditional Main Streets or other locales that come to mind when thinking of distinctive “places” to shop, the tenants in these centers seem to be largely the same as those in regional malls—ubiquitous national chain stores. Due to this lack of local, unique content, these projects in many cases seem to be more a repackaging of the regional mall formula than truly successful attempts at place making. However, despite several challenges to tenanting independent businesses, some owners of new, what I refer to as, Place Making Centers have nonetheless taken a more proactive role in varying their tenant mix so as to better differentiate and reflect the local character of these projects; consciously dedicating a substantial percentage of their retail space for smaller local or regional retailers. This suggests that for some developers and projects these obstacles can be overcome, and that there is some perceived added value, place making or otherwise, to incorporating these businesses. In this thesis, I argue that place making, besides a physical act, also involves an intangible social and cognitive quality. I also assert that independent business can contribute to sense of place by contributing spaces more likely to promote social interaction and adapt over time and by providing a sense of uniqueness, rootedness and authenticity. Furthermore, the characteristics that contribute to the likelihood and/or viability of incorporating independent businesses in a project fall into three categories—owner characteristics, project financing and economics, and market characteristics. In projects that successfully overcome these obstacles, independent businesses are shown to further place making’s aim of overall and long-term value creation, suggesting that incorporation of these retailers should be strongly considered by developers of new retail formats.

The increasing involvement of the private sector in the design and management of urban public space has prompted some critical scholars to predict the ‘end of public space’. This study reassesses the implications of private sector involvement through a comparative analysis of British and Dutch urban spaces, based on a threefold critique of the existing literature on the privatization of public space. The analysis is governed by a new model of pseudo-public space that consists of four dimensions of ‘publicness’: ownership, management, accessibility and inclusiveness (OMAI). The findings suggest that, while there are significant differences between the British and the Dutch cases, neither context supports the notion of a possible ‘end of public space’ in any literal sense.

In this article we aim to utilise and apply ethnomethodological and interactionist principles to the analysis of members’ situated accounts of regenerated urban space. With reference to previous empirical studies we apply membership categorization analysis and the concept of mundane reason to data gathered from situated street level interviews carried out as part of a programme of ethnographic research into the regenerated setting of Cardiff Bay. The article demonstrates that these data yield sociological insight into social actors’ interpretive and interactional reasoning in relation to the negotiation, navigation and comprehension of space and place. Through this work the patterned signatures of the urban interactional order can be identified. Furthermore, we illustrate the forms of emic rationality associated with the everyday and ubiquitous constitution of urban space as a meaningful, and thence cultural, milieu. It is our claim that an appreciation of these urban forms of reasoning is important in the ethnographic, sociological and geographical analysis of space and place.
