The significance of digital data systems for smart city policy

Our planet is gradually moving towards an urbanized world. Modern urban agglomerations tend to turn nowadays into advanced information hubs supporting a smart management of dynamic urban systems. The currently popular notion of ‘smart cities’ aims to provide a new perspective for sustainable and high-performance strategies of city stakeholders in our ‘urban century’. In this context, digital information technology provides a new tool for efficient and effective management and planning of urban space, inter alia in the field of transportation, environment, public facilities or advanced service provision to citizens. This paper aims to offer, first, a concise overview of the emerging opportunities of information and communication technology (ICT) for smart urban policy; digital technology in particular, appears to provide novel pathways for modern planning strategies in smart cities. Against this background, the paper sketches out the complex force field of global urbanisation phenomena and highlights the data and information needs for strategic planning of cities (using inter alia as a framework the so-called ‘urban piazza’ strategy framework). Secondly, various new decision support tools that are currently emerging and that offer a new promising scope for handling complex urban management issues (for instance, on accessibility, congestion, safety or sustainability) are briefly presented. And finally, the potential of such digital data systems for urban management and policy is concisely illustrated by means of some recent applications in the area of smartphone data systems. The paper concludes with a discussion of the challenges ahead for urban policy, inter alia by paying attention to institutional and governance aspects of ‘big digital data’ management in urban systems.     

Skyscrapers and the economy in Latin America

Skyscrapers are an intellectual challenge for urban analysis because of their imposing visual presence in the city landscape, and because of their environmental and real estate impacts. These characteristics however have not received much attention in the literature, particularly in analyses about Latin American cities. In this paper, we describe and test four theories about record-breaking buildings height: traditional microeconomic theory, game theory, business cycle, and global cities. We use a 2000–2012 panel database of 29 cities from 10 different Latin American countries, in order to contrast the contesting explanations about buildings’ height. We design a baseline model and then, using four different estimation techniques and diverse specifications, find that traditional theory and more strongly, global cities are good predictors of buildings’ height.     

Subterranean Commodification: Informal Housing and the Legalization of Basement Suites in Vancouver from 1928 to 2009

This article draws on Margaret Radin's theorization of ‘contested commodities' to explore the process whereby informal housing becomes formalized while also being shaped by legal regulation. In seeking to move once‐informal housing into the domain of official legality, cities can seldom rely on a simple legal framework of private‐law principles of property and contract. Instead, they face complex trade‐offs between providing basic needs and affordability and meeting public‐law norms around living standards, traditional neighbourhood feel and the environment. This article highlights these issues through an examination of the uneven process of legal formalization of basement apartments in Vancouver, Canada. We chose a lengthy period—from 1928 to 2009—to explore how basement apartments became a vital source of housing often at odds with city planning that has long favoured a low‐density residential built form. We suggest that Radin's theoretical account makes it possible to link legalization and official market construction with two questions: whether to permit commodification and how to permit commodification. Real‐world commodification processes—including legal sanction—reflect hybridization, pragmatic decision making and regulatory compromise. The resolution of questions concerning how to legalize commodification are also intertwined with processes of market expansion.     

Creative Cities,Graffiti and Culture-Led Development in South Africa: Dlala Indima (‘Play Your Part’)

Creative cities and culture-led development discourses have come under increasing scrutiny as elite-centric economic development agendas tend to trump ‘civic creativity’ ideals as imagined by Charles Landry. In South Africa, culture-led development and cultural policy tends to primarily mimic that of the global North, largely focusing on culture as a catalyst for economic and property development. Public art commissioning processes tend to focus on decorative projects as part of urban upgrading, which are often associated with ensuing gentrification and displacement of the urban poor. In contrast to focusing on these kinds of regeneration strategies, this article investigates Dlala Indima, a hip-hop-led graffiti project in a rural township in the Eastern Cape of South Africa. This article situates graffiti as a critical social and spatial practice to argue that this case challenges normative cultural planning paradigms. Dlala Indima's work is an alternative approach to cultural development by and for young people who are usually marginalized by the mainstream practice of culture-led economic development. The project challenges dominant creative cities and culture-led development discourses in three ways: first, it challenges the normative processes of regeneration; secondly, it grounds participatory practice; and finally, it shifts participation from ‘tyranny to transformation’ through the ubuntu of hip-hop, the notion of ubuntu being based on the communitarian notion of ‘ubuntu, ngubuntu ngabantu’—‘I am because you are’.     

How do customers meet their needs in in-store and online fashion shopping? A comparative study based on the jobs-to-be-done theory

Understanding customer needs is key for fashion retailers to stay competitive and innovative. Surprisingly, however, extant literature mainly explores customer needs in terms of a garment and its attributes rather than viewing shopping as a problem-solving process to meet customer needs. Moreover, these studies fail to address how customers meet their needs in-store (ISFR) and online fashion retailing (OFR). To fill this research gap, we empirically investigate customers' personal and social needs and how they can be met through the jobs-to-be-done theory. Findings reveal that, beyond the purchase of a garment, customer needs can be fulfilled through different ways, such as smart technology or a person's high interaction with social others in ISFR and the online shop experience or a social linkage without social interaction in OFR. Additionally, our findings offer potential service innovations for fashion retailing managers.

Building from Scratch: New Cities,Privatized Urbanism and the Spatial Restructuring of Johannesburg after Apartheid

By the start of the twenty‐first century, the once dominant historical downtown core of Johannesburg had lost its privileged status as the center of business and commercial activities, the metropolitan landscape having been restructured into an assemblage of sprawling, rival edge cities. Real estate developers have recently unveiled ambitious plans to build two completely new cities from scratch: Waterfall City and Lanseria Airport City (formerly called Cradle City) are master‐planned, holistically designed ‘satellite cities’ built on vacant land. While incorporating features found in earlier city‐building efforts, these two new self‐contained, privately‐managed cities operate outside the administrative reach of public authority and thus exemplify the global trend toward privatized urbanism. Waterfall City, located on land that has been owned by the same extended family for nearly 100 years, is spearheaded by a single corporate entity. Lanseria Airport City/Cradle City is a planned ‘aerotropolis’ surrounding the existing Lanseria airport at the northwest corner of the Johannesburg metropole. These two new private cities differ from earlier large‐scale urban projects because everything from basic infrastructure (including utilities, sewerage, and the installation and maintenance of roadways), landscaping, security services, the regulation of common spaces, and selling and branding the city are firmly in the hands of private profit‐making corporate entities and outside the mandate of public authorities.     

‘Gay Enclaves Face Prospect of Being PassÉ': How Assimilation Affects the Spatial Expressions of Sexuality in the United States

Journalists, activists and academics alike predict that gay neighborhoods in the United States will disappear, yet many of their claims are unsubstantiated or overly determined by economic factors. This article examines 40 years of media accounts to identify the mechanisms that explain why these urban areas are changing. I begin with the observation that the rate of assimilation of sexual minorities into mainstream society has accelerated in today's so‐called ‘post‐gay' era. Assimilation expands the residential imagination of gays and lesbians beyond the boundaries of a specific neighborhood to the entire city itself. Furthermore, as sexual orientation recedes in centrality in everyday life, residents opine that few care if a person self‐identifies as gay or straight. These two respective mechanisms of expansion and cultural sameness bring existing economic wisdom into dialogue with a cultural and political perspective about how our shifting understandings of sexuality also affect the decisions we make about where to live and socialize.
