The aim of this article is to explore new ways of integrating technology, nature and infrastructures into urban public spaces. This is done through a case study, the design of General Vara del Rey, which is offered here as a model to explore a novel urban political ecology that calls into question dominant definitions of public spaces as self‐contained sites operating independently of natural and infrastructural spaces. Through the double movement of ‘the technification of public space’ and ‘the publicization of infrastructures’, the square aims to rethink the political ecology of urban public spaces by enabling the effective incorporation and participation of infrastructural and natural elements as active actors into the public and political life of the community. It is argued that the transformation of infrastructures into fully visible, public and political agents provides a useful model to address the growing proliferation of infrastructural and technological elements onto contemporary urban surfaces and to open up the possibility of new forms of civic participation and engagement.

This study compares community-park design and residents' perceptions of safety in two subdivision communities in The Woodlands, Texas. The communities were built following two different planning approaches—the ecological approach and the conventional approach. Surveys have shown that residents generally feel safer in community parks built according to the latter approach. Using landscape metrics and home-to-park proximity indicators, we examine how different planning approaches affect park design and, as a result, influence residents' perceptions of safety. We cross-validated the results with survey studies conducted over several years. The study findings suggest that park location, spatial configuration of woody vegetation, and management of understory can be important design considerations that impact residents' perceived levels of safety. Park designers and managers should also consider providing parks that meet diverse needs and balance the requirements of ecological preservation, aesthetics, and cultural preference.

This study examines the extent to which specific social and environmental objectives have been achieved in the new urbanist community of Orenco Station (Portland, Oregon). House-level surveys were conducted in Orenco Station, as well as a traditional suburb and two long- established urban neighborhoods. Survey data reveal high levels of social interaction in the new urbanist community, as compared to the comparison neighborhoods. The analysis also reveals a higher level of walking, and an increase in the occasional use of mass transit, in the new urbanist community. However, the majority of residents in all four neighborhoods (including the new urbanist neighborhood) rely on single occupancy vehicles for their regular commute. In sum, this study shows that Orenco Station is very effective in achieving its social objectives, modestly effective in encouraging waling and the occasional use of mass transit–but not very effective in increasing primary reliance on mass transit for commuting.

This paper assesses and synthesizes the cumulative results of a new “neighborhood-effects” literature that examines social processes related to problem behaviors and health-related outcomes. Our review identified over 40 relevant studies published in peer-reviewed journals from the mid-1990s to 2001, the take-off point for an increasing level of interest in neighborhood effects. Moving beyond traditional characteristics such as concentrated poverty, we evaluate the salience of social-interactional and institutional mechanisms hypothesized to account for neighborhood-level variations in a variety of phenomena (e.g., delinquency, violence, depression, high-risk behavior), especially among adolescents. We highlight neighborhood ties, social control, mutual trust, institutional resources, disorder, and routine activity patterns. We also discuss a set of thorny methodological problems that plague the study of neighborhood effects, with special attention to selection bias. We conclude with promising strategies and directions for future research, including experimental designs, taking spatial and temporal dynamics seriously, systematic observational approaches, and benchmark data on neighborhood social processes.
