A significant body of research has addressed whether fixed internet use increases, decreases or supplements the ways in which people engage in residential and workplace settings, but few studies have addressed how wireless internet use in public and semi-public spaces influences social life. Ubiquitous wi-fi adds a new dimension to the debate over how the internet may influence the structure of community.Will wireless internet use facilitate greater engagement with co-located others or encourage a form of 'public privatism'? This article reports the findings of an exploratory ethnographic study of how wi-fi was used and influenced social interactions in four different settings: paid and free wi-fi cafes in Boston, MA and Seattle,WA.This study found contrasting uses for wireless internet and competing implications for community.Two types of practices, typified in the behaviors of 'true mobiles' and 'placemakers', offer divergent futures for how wireless internet use may influence social relationships.

This paper empirically explores the management of privately owned public space. It examines 163 spaces produced through New York City’s incentive zoning programme, whereby developers provide and manage a public space in exchange for fl oor area ratio (FAR) bonuses. Developers of these bonus spaces employ a variety of management approaches, each correlating with common theories of spatial control in publicly owned spaces. However, as developer priorities are often fi scally driven, most approaches severely limit political, social and democratic functions of public space and produce a constricted defi nition of the public. As such, privately owned public spaces have deleterious effects on concepts of citizenship and representation, even as they become the new models for urban space provision and management.

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.
