Evaluating the Impact of an Integrated Urban Design of Transport Infrastructure and Public Space on Human Behavior and Environmental Quality: A Case Study in Beijing
Urban transport infrastructure can result in the physical, psychological and environmental separation of neighborhoods, public spaces and pedestrian networks, leading to negative impacts on citizens’ daily commutes, social activities and the quality of the ecosystem. An integrated design of transport infrastructure and public space is beneficial for mediating these negative impacts. In this paper, we propose an integrated methodology, which combines urban design, computational scenario evaluation and decision-making processes, based on a conceptual model of human and ecological needs-driven planning. To evaluate the impacts of the road network and public space design on individual outdoor activities, travel behavior and air pollution, an agent-based model is demonstrated. This model is then applied to a case study in Beijing, leading to hourly traffic volume maps and car-related air pollution heat maps of a baseline road network-public space design
Green-Networks: Integrating Alternative Circulation Systems into Post-industrial Cities
Many post-industrial cities are infused with ready-made spaces for non-vehicular circulation in the form of webs of linear voids that often result from industrial era infrastructure. There have been many successful conversions of individual linear easements into greenways, although attempting to craft continuous green-networks from these residual spaces is often problematic. This paper considers how designers and planners might start to reconcile the aspirations of the green-network as a model and an idea with the actual opportunities on the ground as typically found in post-industrial cities. Central to the discussion is an extension of Robert Searns' greenway generational rubric, whereby the present generation of greenways is described as complete webs to rival the grey infrastructure of the incumbent city fabric. Within this framework, the paper elaborates on a number of themes: (1) how effective green-networks are at influencing urban form; (2) the green-network as a counterbalance to the city; (3) speed versus slowness; (4) issues of intersection and grade separation; (5) the concept of interwoven green/grey space; and (6) the greenway network model versus the standalone circuit. The paper concludes with a call for expanding the greenway nomenclature to reflect the actual diversity of the genre. © 2013 Copyright Taylor and Francis Group, LLC
Reliving the Past & Making a Harmonious Society Today
This paper tells a story of DIY (do it yourself) making that does not neatly fit more familiar narratives of making: as individual empowerment, as a democratizing force, and as technoscientific innovation. Drawing on ethnographic research with a collective of elderly electronic hackers in China, we provide insights into the socio-technical and politico-economic processes of hacking and making. This paper examines how the activity of making functioned for elderly DIY enthusiasts as way of remaking and reliving the past and as a means for expressing class belonging and citizenship. We show that making and hacking is not practiced in a void independent of social, political or economic forces. Rather, making unfolds in relation to, and is contingent on, societal norms and specific techno-cultural histories. As much as hacking empowers certain people, it excludes others and functions as a site for the exercise of power and social distinction making
Comparing Print Coverage and Tweets in Elections: a Case Study of the 2011-2012 US Republican Primaries
Social media platforms including Facebook, Twitter, and Tumblr, etc. have become more ubiquitous. They have had an increasing role in social movements, elections, and everyday life around the world. Social science is well positioned to explore the power and influence of social media economically, politically, and socially. This article is particularly interested in evaluating whether the sentiment of traditional print media coverage during elections has any relationship to the frequency of election-related tweets. Though television is perhaps more influential in terms of political news, social media is often used to retweet or comment on articles from print journalism. Also, though we increasingly consume news from social media, we often do not think of how opinions are converging or divergent during major events. This article specifically explores the case of the 2011-2012 US Republican primaries. 99 randomly selected articles from the New York Times, the Wall Street Journal and the Washington Post covering Republican primary debates were hand coded for sentiment and compared with the frequency and sentiment of candidate-related geo-located tweets from urban American users. We also explored whether there is any relationship between print media, and tweet sentiment briefly. Overall, the newspapers sampled as a whole had a weak relationship to tweet frequency and sentiment. Though there is a large presence of journalists on Twitter, the medium is clearly not a facsimile of print media and that other opinions, values, and sentiments may have a stronger influence within the medium. This study is significant both in its mixed methods approach as well as its finding that traditional print media coverage is not generally related to the frequency or sentiment of election-related tweets despite Twitter’s role as a key space for news production and consumption
An Interdisciplinary Methodology for the Characterization and Visualization of the Heritage of Roadway Corridors
Roads, particularly since the advent of motorized traffic, have hugely impacted contemporary landscapes. Although their significance was noted in the 1980s, specific roadway-heritage studies are scarce. Research in different disciplines has identified certain features of roads, but an integrated approach to roadway heritage or a consensus on what this constitutes are lacking. This article proposes an interdisciplinary methodology to assess roadway heritage. Roadways are interpreted within the framework of semantic openness that currently characterizes heritage studies, territory being the basic element of interpretation. Rather than a fragmented approach to conservation, the research defines integrated heritage configurations where natural, cultural, and historical features combine to produce a cohesive form of heritage. GIS (Geographical information systems) technology is used with an online database to assess the complexity of roadway heritage. ICT (Information and communications technology) strategies to raise public awareness are outlined. The methodology is applied to assess the historical N-340 Mediterranean roadway corridor in Spain
Pirate panics : comparing news and blog discourse on illegal file sharing in Sweden
This paper aimed at examining the barriers to and facilitators of disseminating and utilizing the results of a local Swedish school survey. Interviews with 21 school district managers/principals were performed. Results showed that dissemination and utilization of local survey data appeared as two interrelated processes. With those processes, various barriers and facilitators were mentioned. The barriers and facilitators were not merely the opposites of each other; instead they qualitatively differed from each other depending on what phase in the process the manager/principal referred to. The results also showed that the dissemination phase was both a prerequisite for and interwoven with the utilization phase, e.g. dissemination efforts were important for how the survey results were utilized
