Detroit Revitalizes City with 311 App

Curated on May 15, 2015May 29, 2019 by Stefaan Verhulst

Jason Shueh at Government Technology: “In the wake of the Detroit bankruptcy, blight sieged parts of the city as its populous exited. The fallouts were typical. There was a run of vandalism, thefts, arson and graffiti. Hard times pushed throngs of looters into scores of homes to scavenge for anything that wasn’t bolted down — and often, even for the things that were…. For solutions, Detroit Mayor Mike Duggan and DWSD’s CIO Dan Rainey partnered with SeeClickFix. The company, based in New Haven, Conn., is known for its mobile platform that’s embedded itself as a conduit between city service departments and citizen non-emergency — or 311 — requests. Duggan saw the platform as an opportune answer to address more than a single issue. Instead, the mayor asked how the app could be integrated throughout the city. Potholes, downed trees, graffiti, missing signage, streetlight outages — the mayor wanted a bundled solution to handle an array of common challenges.

Improve Detroit was his answer. The city app, officially available since April, allows citizens to report problems using photos, location data and by request type. Notifications on progress follow and residents can even pay utility bills through the app. For departments, it’s ingrained into work orders and workflows, while analytics provide data for planning, and filters permit a deep-dive analysis….

Detroit now sits among many metropolitan cities pioneering such 311 apps. San Francisco, New York, Los Angeles, Philadelphia and Chicago are just a few of them. And there are a host of equally adroit tech providers supplying and supporting the apps — companies like Salesforce, CitySourced, PublicStuff, Fix 311 and others. Some cities have even developed their own apps through their internal IT departments.

What’s unique in Detroit is the city’s ambition to leverage a 311 app against major blight while the city works to demolish more than 20,000 abandoned homes — susceptible to fire, flooding, pest infestations and criminal activity. Beyond this, Lingholm said the initiative doubles as a tool to rejuvenate public trust. Data from the app is fed to the city’s new open data portal, and departments have set goals to ensure responsiveness….(More)

How to use mobile phone data for good without invading anyone’s privacy

Curated on May 14, 2015August 3, 2018 by Stefaan Verhulst

Leo Mirani in Quartz: “In 2014, when the West African Ebola outbreak was at its peak, some academics argued that the epidemic could have been slowed by using mobile phone data.

Their premise was simple: call-data records show the true nature of social networks and human movement. Understanding social networks and how people really move—as seen from phone movements and calls—could give health officials the ability to predict how a disease will move and where a disease will strike next, and prepare accordingly.

The problem is that call-data records are very hard to get a hold of. The files themselves are huge, there are enormous privacy risks, and the process of making the records safe for distribution is long.
First, the technical basics

Every time you make a phone call from your mobile phone to another mobile phone, the network records the following information (note: this is not a complete list):

The number from which the call originated
The number at which the call terminated
Start time of the call
Duration of the call
The ID number of the phone making the call
The ID number of the SIM card used to make the call
The code for the antenna used to make the call

On their own, these records are not creepy. Indeed, without them, networks would be unable to connect calls or bill customers. But it is easy to see why operators aren’t rushing to share this information. Even though the data includes none of the actual content of a phone call in the data, simply knowing which number is calling which, and from where and when, is usually more than enough to identify people.
So how can network operators use this valuable data for good while also protecting their own interests and those of their customers? A good example can be found in Africa, where Orange, a French mobile phone network with interests across several African countries, has for the second year run its “Data for Development” (D4D) program, which offers researchers a chance to mine call data for clues on development problems.

Steps to safe sharing

After a successful first year in Ivory Coast, Orange this year ran the D4D program in Senegal. The aim of the program is to give researchers and scientists at universities and other research labs access to data in order to find novel ways to aid development in health, agriculture, transport or urban planning, energy, and national statistics….(More)”

Citizen Science in the Unexplored Terrain of the Brain

Curated on May 14, 2015May 29, 2019 by Stefaan Verhulst

Aaron Krol at BioITWorld: “The game is simple. On the left-hand side of the screen you see a cube containing a misshapen 3D figure, a bit like a tree branch with a gall infestation. To the right is a razor-thin cross-section of the cube, a grainy image of overlapping gray blobs. Clicking on a blob colors it in, like using the paint bucket tool in MS Paint, while also sending colorful extensions out from the branch to the left. Working your way through 256 of these cross-sections, your job is to extend the branch through the cube, identifying which blobs are continuous with the branch and which are nearby distractions.
It hardly sounds like a game at all, but strange to say, there’s something very compelling about playing EyeWire. Maybe it’s watching the branches grow and fork as you discover new connections. Maybe it’s how quickly you can rack up progress, almost not noticing time go by as you span your branches through cube after cube.
“It draws you in,” says Nikitas Serafetinidis ― or Nseraf, as he’s known in-game. “There’s an unexplained component that makes this game highly addictive.”
Serafetinidis is the world record holder in EyeWire, a game whose players are helping to build a three-dimensional map of brain cells in the retina. The images in EyeWire are in fact photos taken with an electron microscope at the Max Planck Institute of Medical Research in Heidelberg: each one represents a tiny sliver of a mouse’s retina, just 20 nanometers thick. The “blobs” are thin slices of closely adjoined neurons, and the “branch” shows the path of a single cell, which can cross through hundreds of thousands of those images….(More)”

The Hague Declaration on Knowledge Discovery in the Digital Age

Curated on May 14, 2015August 3, 2018 by Stefaan Verhulst

The Hague Declaration: “New technologies are revolutionising the way humans can learn about the world and about themselves. These technologies are not only a means of dealing with Big Data¹, they are also a key to knowledge discovery in the digital age; and their power is predicated on the increasing availability of data itself. Factors such as increasing computing power, the growth of the web, and governmental commitment to open access² to publicly-funded research are serving to increase the availability of facts, data and ideas.

However, current legislative frameworks in different legal jurisdictions may not be cast in a way which supports the introduction of new approaches to undertaking research, in particular content mining. Content mining is the process of deriving information from machine-readable material. It works by copying large quantities of material, extracting the data, and recombining it to identify patterns and trends.

At the same time, intellectual property laws from a time well before the advent of the web limit the power of digital content analysis techniques such as text and data mining (for text and data) or content mining (for computer analysis of content in all formats)³. These factors are also creating inequalities in access to knowledge discovery in the digital age. The legislation in question might be copyright law, law governing patents or database laws – all of which may restrict the ability of the user to perform detailed content analysis.

Researchers should have the freedom to analyse and pursue intellectual curiosity without fear of monitoring or repercussions. These freedoms must not be eroded in the digital environment. Likewise, ethics around the use of data and content mining continue to evolve in response to changing technology.

Computer analysis of content in all formats, that is content mining, enables access to undiscovered public knowledge and provides important insights across every aspect of our economic, social and cultural life. Content mining will also have a profound impact for understanding society and societal movements (for example, predicting political uprisings, analysing demographical changes). Use of such techniques has the potential to revolutionise the way research is performed – both academic and commercial….(More: Declaration (PDF); Infographic)”

Social network targeting to maximise population behaviour change: a cluster randomised controlled trial

Curated on May 14, 2015August 3, 2018 by Stefaan Verhulst

Paper by Prof. Nicholas A Christakis et al in The Lancet: “Information and behaviour can spread through interpersonal ties. By targeting influential individuals, health interventions that harness the distributive properties of social networks could be made more effective and efficient than those that do not. Our aim was to assess which targeting methods produce the greatest cascades or spillover effects and hence maximise population-level behaviour change…..Deployment of certain types of health interventions via network targeting, without increasing the number of individuals targeted or the resources used, could enhance the adoption and efficiency of those interventions, thereby improving population health….(More)

Slacktivism and the social benefits of social video: Sharing a video to ‘help’ a cause

Curated on May 14, 2015October 23, 2018 by Stefaan Verhulst

Cat Jones at FirstMonday: “Interest in online ‘slacktivism’ is high both within and outside academia, and the online sharing of cause-related campaigns is increasing, but research into the extent to which ‘slacktivism’ applies to the act of sharing online content to ‘help’ a cause is limited. Slacktivism, as used in much of today’s popular discourse, is defined as ‘feel-good online activism [with] zero political or social impact’ (Morozov, 2009). Here, a survey-based analysis investigates social videos’ impacts on U.K. and U.S. viewers. Results show that the stronger viewers’ motivations are to share to help a cause, the stronger their motivations are to find out more afterwards. Further, a case study shows that social videos that motivate viewers to share the video ‘because it’s for a good cause, and I want to help’ (cause-related sharing versus, for example, to appear knowledgeable about a subject), can also prompt real-life actions, including donations. These results indicate that cause-related video sharing does have an impact, and therefore is not slacktivism by Morozov’s definition. Preliminary analysis suggests that of viewers sharing to ‘help’ causes, those discriminating in their choice of sharing audience (narrow vs. broad) are more likely to further engage than indiscriminate sharers. Result patterns from U.S. narrowcast sharers differ from those of other groups, indicating that tie strength and cultural differences may play a role in modifying slacktivist behaviors….(More)”

Crowdsourced website flags up sexism in the workplace

Curated on May 13, 2015August 3, 2018 by Stefaan Verhulst

Springwise: “Female jobseekers can now review the treatment of women in their potential workplace via an online platform called InHerSight. The website collates anonymous reviews from former and current employees — both male and female — so that women can find out more about the company’s policies, office culture and other potential issues before applying for or accepting a job there.

A recent survey by Cosmopolitan magazine found that one in three women are sexually harassed at work and InHerSight enables those women to communicate misconduct and other problematic corporate policies. Importantly, they can do so without fear of recrimination or consequence, since the scorecards are entirely anonymous. Users can complete surveys about their experience at any given company — either adding to an existing score or creating a new profile — by scoring them on 14 categories including their stance on maternity leave, flexible work hours and female representation in top positions. They can also leave a written review of the company. The crowdsourced data is then used to create comprehensive scorecards for other users to view.

Founder Ursula Mead envisions the site as a TripAdvisor for women in the workplace and hopes that by holding companies accountable for their support for women, it will encourage them to review and improve their treatment….(More)”
