The “broken-windows theory,” which was propounded by two Harvard University researchers in the early 1980s, holds that urban “disorder” — visible signs of neglect, such as broken windows — actually promotes crime, initiating a vicious feedback loop. The theory was the basis for former New York mayor Rudy Giuliani’s crackdown on petty crime, but it’s come under sharp criticism from some social scientists. One of the difficulties in evaluating the theory is that it’s hard to quantify something as subjective as visible disorder.
In the latest issue of the journal PLoS One, researchers from MIT’s Media Lab present a new online tool that they hope will help social scientists take a more rigorous look at city dwellers’ emotional responses to their environments. The tool presents online volunteers with pairs of images randomly drawn from Google Maps’ compendium of street-level photographs; each volunteer selects the image that better represents some qualitative attribute. Algorithms use the results of the pairwise comparisons to assign geographical areas scores, from one to 10, on each attribute.
In the experiments reported in the PLoS One paper, volunteers ranked the neighborhoods depicted in the images according to how safe they looked, how “upper-class,” and how “unique” — an attribute selected in the hope that it would not be strongly correlated with the other two. The researchers found that the scores for the U.S. cities selected for the study — New York and Boston — showed greater disparity between the extremes for both class and safety than did those for the two Austrian cities selected, Linz and Salzburg.
They also found that, controlled for income, area, and population, the perceived-safety scores for neighborhoods in New York correlated very well with incidence of violent crime”.

Facebook Is Being Redefined by Its Developing World Users

Curated on July 23, 2013August 3, 2018 by Stefaan Verhulst

Tom Simonite in MIT Technology Review: “…as Facebook’s user base continues to expand, a growing proportion of its users think of it quite differently, as a luxury brand, badge of status, and or even a place to make a little extra money. That’s due to the rapid growth in the number of Facebook users signing on from developing countries, a trend underscored by news from the company today that more than 100 million people use a mobile app the company makes for feature phones…
Little research has been done on Facebook’s growth in developing countries (and a lot would be needed to capture even some of the diversity included under the blanket term “developing world”). Two small, recent studies of Kenyan Facebook users in poor areas by Susan Wyche of Michigan State University are among the first to be published, and they provide some interesting insights.
One of Wyche’s ethnographic studies took place in rural Internet cafes, where the researchers were told that “Facebook is a luxury,” only to be indulged if someone had money to spare (here’s a PDF of Wyche’s paper). When study participants thought about social networking, the challenges of low bandwidth and sometimes unreliable electricity supplies were foremost in their minds.
The barriers of cost and infrastructure associated with Facebook led people in another community Wyche and colleagues visited, a slum of Nairobi, to see the service as for more than just socializing. They used it—with mixed success—as a way to make a little money, look for jobs, market themselves, and seek remittances from friends and family overseas. (This reminded me of a recent report on people in Kuwait using Instagram to sell things and run retail businesses.)…
Should it want to, Facebook could even become a powerful tool for efforts to improve the lives of people in poor areas, where the site is gaining traction. The company has already dabbled with using social engineering to boost organ donations in the U.S. (see “Thank God for Facebook: When Platforms Proselytize”). There’s no shortage of similar experiments that could be run in places with more fundamental health problems, where Facebook’s status as a luxury could make it very influential.”

Accountability.Org: Online Disclosure by Nonprofits

Curated on July 18, 2013December 6, 2018 by Stefaan Verhulst

Paper by Joannie Tremblay-Boire and Aseem Prakash: “Why do some nonprofits signal their accountability via unilateral website disclosures? We develop an Accountability Index to examine the websites of 200 U.S. nonprofits ranked by the Chronicle of Philanthropy. We expect nonprofits’ incentives for website disclosures will be shaped by their organizational and sectoral characteristics. Our analysis suggests that nonprofits appearing frequently in the media disclose more accountability information while nonprofits larger in size disclose less. Religion-related nonprofits tend to disclose less information, suggesting that religious bonding enhances trust and reduce incentives for self-disclosure. Health nonprofits disclose less information, arguably because government-mandated disclosures reduce marginal benefits from voluntary disclosures. Education nonprofits, on the other hand, tend to disclose more accountability information perhaps because they supply credence goods. This research contributes to the emerging literature on websites as accountability mechanisms by developing a new index for scholars to use and proposing new hypotheses based on the corporate social responsibility literature.”

Understanding Smart Data Disclosure Policy Success: The Case of Green Button

Curated on July 17, 2013August 3, 2018 by Stefaan Verhulst

New Paper by Djoko Sigit Sayogo and Theresa Pardo: “Open data policies are expected to promote innovations that stimulate social, political and economic change. In pursuit of innovation potential, open datahas expanded to wider environment involving government, business and citizens. The US government recently launched such collaboration through a smart data policy supporting energy efficiency called Green Button. This paper explores the implementation of Green Button and identifies motivations and success factors facilitating successful collaboration between public and private organizations to support smart disclosure policy. Analyzing qualitative data from semi-structured interviews with experts involved in Green Button initiation and implementation, this paper presents some key findings. The success of Green Button can be attributed to the interaction between internal and external factors. The external factors consist of both market and non-market drivers: economic factors, technology related factors, regulatory contexts and policy incentives, and some factors that stimulate imitative behavior among the adopters. The external factors create the necessary institutional environment for the Green Button implementation. On the other hand, the acceptance and adoption of Green Button itself is influenced by the fit of Green Button capability to the strategic mission of energy and utility companies in providing energy efficiency programs. We also identify the different roles of government during the different stages of Green Button implementation.”

The Real-Time City? Big Data and Smart Urbanism

Curated on July 9, 2013December 6, 2018 by Stefaan Verhulst

New paper by Rob Kitchin from the National University of Ireland, Maynooth (NUI Maynooth) – NIRSA: “‘Smart cities’ is a term that has gained traction in academia, business and government to describe cities that, on the one hand, are increasingly composed of and monitored by pervasive and ubiquitous computing and, on the other, whose economy and governance is being driven by innovation, creativity and entrepreneurship, enacted by smart people. This paper focuses on the former and how cities are being instrumented with digital devices and infrastructure that produce ‘big data’ which enable real-time analysis of city life, new modes of technocratic urban governance, and a re-imagining of cities. The paper details a number of projects that seek to produce a real-time analysis of the city and provides a critical reflection on the implications of big data and smart urbanism”

City Data: Big, Open and Linked

Curated on July 8, 2013October 9, 2018 by Stefaan Verhulst

Working Paper by Mark S. Fox (University of Toronto): “Cities are moving towards policymaking based on data. They are publishing data using Open Data standards, linking data from disparate sources, allowing the crowd to update their data with Smart Phone Apps that use Open APIs, and applying “Big Data” Techniques to discover relationships that lead to greater efficiencies.
One Big City Data example is from New York City (Schönberger & Cukier, 2013). Building owners were illegally converting their buildings into rooming houses that contained 10 times the number people they were designed for. These buildings posed a number of problems, including fire hazards, drugs, crime, disease and pest infestations. There are over 900,000 properties in New York City and only 200 inspectors who received over 25,000 illegal conversion complaints per year. The challenge was to distinguish nuisance complaints from those worth investigating where current methods were resulting in only 13% of the inspections resulting in vacate orders.
New York’s Analytics team created a dataset that combined data from 19 agencies including buildings, preservation, police, fire, tax, and building permits. By combining data analysis with expertise gleaned from inspectors (e.g., buildings that recently received a building permit were less likely to be a problem as they were being well maintained), the team was able to develop a rating system for complaints. Based on their analysis of this data, they were able to rate complaints such that in 70% of their visits, inspectors issued vacate orders; a fivefold increase in efficiency…
This paper provides an introduction to the concepts that underlie Big City Data. It explains the concepts of Open, Unified, Linked and Grounded data that lie at the heart of the Semantic Web. It then builds on this by discussing Data Analytics, which includes Statistics, Pattern Recognition and Machine Learning. Finally we discuss Big Data as the extension of Data Analytics to the Cloud where massive amounts of computing power and storage are available for processing large data sets. We use city data to illustrate each.”

E-petition systems and political participation: About institutional challenges and democratic opportunities

Curated on July 8, 2013August 3, 2018 by Stefaan Verhulst

New paper by Knud Böhle and Ulrich Riehm in First Monday: “The implementation of e–petition systems holds the promise to increase the participative and deliberative potential of petitions. The most ambitious e–petition systems allow for electronic submission, make publicly available the petition text, related documents and the final decision, allow supporting a petition by electronically co–signing it, and provide electronic discussion forums. Based on a comprehensive survey (2010/2011) of parliamentary petition bodies at the national level covering the 27 member states of the European Union (EU) plus Norway and Switzerland, the state of public e–petitioning in the EU is presented, and the relevance of e–petition systems as a means of political participation is discussed….
The most interesting finding is that some petition systems — by leveraging the potential of the Internet — further the involvement of the public considerably. This happens in two ways: first by nudging e–petition systems in the direction of lightweight instruments of direct democracy and second by making the institution itself more open, transparent, accountable, effective, and responsive through the involvement of the public. Both development paths might also lead to expectations that eventually cannot be complied with by the petition body without more substantial transformations of the institution. This or that might happen. Empirically, we ain’t seen almost nothing yet.”

Targeting Transparency

Curated on June 21, 2013May 29, 2019 by Stefaan Verhulst

New paper by David Weil, Mary Graham, and Archon Fung in Science Magazine: “When rules, taxes, or subsidies prove impractical as policy tools, governments increasingly employ “targeted transparency,” compelling disclosure of information as an alternative means of achieving specific objectives. For example, the U.S. Affordable Care Act of 2010 requires calories be posted on menus to enlist both restaurants and patrons in the effort to reduce obesity. It is crucial to understand when and how such targeted transparency works, as well as when it is inappropriate. Research about its use and effectiveness has begun to take shape, drawing on social and behavioral scientists, economists, and legal scholars. We explore questions central to the performance of targeted transparency policies.

Targeted transparency differs from broader “right-to-know” and “open-government” policies that span from the 1966 Freedom of Information Act to the Obama Administration’s “open-government” initiative encouraging officials to make existing data sets readily available and easy to parse as an end in itself (1, 2). Targeted transparency offers a more focused approach often used to introduce new scientific evidence of public risks into market choices. Government compels companies or agencies to disclose information in standardized formats to reduce specific risks, to ameliorate externalities arising from a failure of consumers or producers to fully consider social costs associated with a product, or to improve provision of public goods and services. Such policies are more light-handed than conventional regulation, relying on the power of information rather than on enforcement of rules and standards or financial inducements….”

Does transparency lead to trust? Some evidence on the subject.

Curated on June 20, 2013December 6, 2018 by Stefaan Verhulst

Tiago Peixoto at DemocracySpot: “As open government gains traction in the international agenda, it is increasingly common to come across statements that assume a causal relationship in which transparency leads to trust in government. But to what extent are claims that transparency leads to trust backed up by evidence?
Judging from some recent publications on the subject, such a relationship is not as straightforward as sadvocates would like. In fact, in a number of cases, the evidence points in another direction: that is, transparency may ultimately decrease trust.
Below is a brief overview of research that has been carried out on the subject…
Surely, transparency remains an essential – although quite insufficient – ingredient of accountability. On the trust issue, one could easily think of a number of scenarios in which it is actually better that citizens do not trust their governments. In fact, systems of checks and balances and oversight institutions are not specifically conceived under the logic of trust. Quite on the contrary, such institutional designs assume some level of suspicion vis-à-vis governments: as put in the Federalist Paper No. 51, “If angels were to govern men, neither external nor internal controls on government would be necessary.”
Granted, in some cases a perfect world in which citizens trust their governments may well be desirable. It may even be that transparency leads – in the long run – to increased trust: a great way to sell transparency to governments. But if we want to walk the talk of evidence-based policymaking, we may consider dropping the trust rhetoric. At least for now.”
