Sarah Laskow at NextCity: “Boston University and University of Pittsburgh researchers are trying to do the same thing that got the creators of the app SketchFactor into so much trouble over the summer. They’re trying to show people how to avoid dangerous spots on city streets while walking from one place to another.
“What we are interested in is finding paths that offer trade-offs between safety and distance,” Esther Galbrun, a postdoc at Boston University, recently said in New York at the 3rd International Workshop on Urban Computing, held in conjunction with KDD2014.
She was presenting, “Safe Navigation in Urban Environments,” which describes a set of algorithms that would give a person walking through a city options for getting from one place to another — the shortest path, the safest path and a number of alternatives that balanced between both factors. The paper takes existing algorithms, well defined in theory — nothing new or fancy, Galbrun says — and applies them to a problem that people face everyday.
Imagine, she suggests, that a person is standing at the Philadelphia Museum of Art, and he wants to walk home, to his place on Wharton Street. (Galbrun and her colleagues looked at Philadelphia and Chicago because those cities have made their crime data openly available.) The walk is about three miles away, and one option would be to take the shortest path back. But maybe he’s worried about safety. Maybe he’s willing to take a little bit of a longer walk if it means he has to worry less about crime. What route should he take then?
Services like Google Maps have excelled at finding the shortest, most direct routes from Point A to Point B. But, increasingly, urban computing is looking to capture other aspects of moving about a place. “Fast is only one option,” says co-author Konstantinos Pelechrinis. “There are noble objectives beyond the surface path that you can put inside this navigation problem.” You might look for the path that will burn the most calories; a Yahoo! lab has considered how to send people along the most scenic route.
But working on routes that do more than give simple directions can have its pitfalls. The SketchFactor app relies both on crime data, when it’s available, and crowdsourced comments to reveal potential trouble spots to users. When it was released this summer, tech reporters and other critics immediately started talking about how it could easily become a conduit for racism. (“Sketchy” is, after all, a very subjective measure.)
So far, though, the problem with the SketchFactor app is less that it offers racially skewed perspectives than that the information it does offer is pretty useless — if entertaining. A pinpoint marked “very sketchy” is just as likely to flag an incident like a Jewish man eating pork products or hipster kids making too much noise as it is to flag a mugging.
Here, then, is a clear example of how Big Data has an advantage over Big Anecdata. The SafePath set-up measures risk more objectively and elegantly. It pulls in openly available crime data and considers simple data like time, location and types of crime. While a crime occurs at a discrete point, the researchers wanted to estimate the risk of a crime on every street, at every point. So they use a mathematical tool that smooths out the crime data over the space of the city and allows them to measure the relative risk of witnessing a crime on every street segment in a city….”
What Is Big Data?
datascience@berkeley Blog: ““Big Data.” It seems like the phrase is everywhere. The term was added to the Oxford English Dictionary in 2013 
, appeared in Merriam-Webster’s Collegiate Dictionary by 2014 , and Gartner’s just-released 2014 Hype Cycle shows “Big Data” passing the “Peak of Inflated Expectations” and on its way down into the “Trough of Disillusionment.” Big Data is all the rage. But what does it actually mean?
A commonly repeated definition cites the three Vs: volume, velocity, and variety. But others argue that it’s not the size of data that counts, but the tools being used, or the insights that can be drawn from a dataset.
To settle the question once and for all, we asked 40+ thought leaders in publishing, fashion, food, automobiles, medicine, marketing and every industry in between how exactly they would define the phrase “Big Data.” Their answers might surprise you! Take a look below to find out what big data is:

Rethinking Democracy
Dani Rodrik at Project Syndicate: “By many measures, the world has never been more democratic. Virtually every government at least pays lip service to democracy and human rights. Though elections may not be free and fair, massive electoral manipulation is rare and the days when only males, whites, or the rich could vote are long gone. Freedom House’s global surveys show a steady increase from the 1970s in the share of countries that are “free” – a trend that the late Harvard political scientist Samuel Huntington dubbed the “third wave” of democratization….
A true democracy, one that combines majority rule with respect for minority rights, requires two sets of institutions. First, institutions of representation, such as political parties, parliaments, and electoral systems, are needed to elicit popular preferences and turn them into policy action. Second, democracy requires institutions of restraint, such as an independent judiciary and media, to uphold fundamental rights like freedom of speech and prevent governments from abusing their power. Representation without restraint – elections without the rule of law – is a recipe for the tyranny of the majority.
Democracy in this sense – what many call “liberal democracy” – flourished only after the emergence of the nation-state and the popular upheaval and mobilization produced by the Industrial Revolution. So it should come as no surprise that the crisis of liberal democracy that many of its oldest practitioners currently are experiencing is a reflection of the stress under which the nation-state finds itself….
In developing countries, it is more often the institutions of restraint that are failing. Governments that come to power through the ballot box often become corrupt and power-hungry. They replicate the practices of the elitist regimes they replaced, clamping down on the press and civil liberties and emasculating (or capturing) the judiciary. The result has been called “illiberal democracy” or “competitive authoritarianism.” Venezuela, Turkey, Egypt, and Thailand are some of the better-known recent examples.
When democracy fails to deliver economically or politically, perhaps it is to be expected that some people will look for authoritarian solutions. And, for many economists, delegating economic policy to technocratic bodies in order to insulate them from the “folly of the masses” almost always is the preferred approach.
…
Effective institutions of restraint do not emerge overnight; and it might seem like those in power would never want to create them. But if there is some likelihood that I will be voted out of office and that the opposition will take over, such institutions will protect me from others’ abuses tomorrow as much as they protect others from my abuses today. So strong prospects for sustained political competition are a key prerequisite for illiberal democracies to turn into liberal ones over time.
Optimists believe that new technologies and modes of governance will resolve all problems and send democracies centered on the nation-state the way of the horse-drawn carriage. Pessimists fear that today’s liberal democracies will be no match for the external challenges mounted by illiberal states like China and Russia, which are guided only by hardnosed realpolitik. Either way, if democracy is to have a future, it will need to be rethought.”
From “Bitcoin to Burning Man and Beyond”
IDCubed: “From Bitcoin to Burning Man and Beyond: The Quest for Autonomy and Identity in a Digital Society explores a new generation of digital technologies that are re-imagining the very foundations of identity, governance, trust and social organization.
The fifteen essays of this book stake out the foundations of a new future – a future of open Web standards and data commons, a society of decentralized autonomous organizations, a world of trustworthy digital currencies and self-organized and expressive communities like Burning Man.
Among the contributors are Alex “Sandy” Pentland of the M.I.T. Human Dynamics Laboratory, former FCC Chairman Reed E. Hundt, long-time IBM strategist Irving Wladawksy-Berger, monetary system expert Bernard Lietaer, Silicon Valley entrepreneur Peter Hirshberg, journalist Jonathan Ledgard and H-Farm cofounder Maurizio Rossi.
From Bitcoin to Burning Man and Beyond was edited by Dr. John H. Clippinger, cofounder and executive director of ID3, and David Bollier, an Editor at ID3 who is also an author, blogger and scholar who studies the commons. The book, published by ID3 in association with Off the Common Books, reflects ID3’s vision of the huge, untapped potential for self-organized, distributed governance on open platforms.
The book is available in print and ebook formats (Kindle and epub) from Amazon.com and Off the Common Books. The book, licensed under a Creative Commons Attribution-NonCommercial-ShareAlike license (BY-NC-SA), may also be downloaded for free as a pdf file from ID3.
One chapter that inspires the book’s title traces the 28-year history of Burning Man, the week-long encampment in the Nevada desert that have hosted remarkable experimentation in new forms of self-governance by large communities. Other chapters explore such cutting-edge concepts as
- evolvable digital contracts that could supplant conventional legal agreements;
- smartphone currencies that could help Africans meet their economic needs more effective;
- the growth of the commodity-backed Ven currency; and
- new types of “solar currencies” that borrow techniques from Bitcoin to enable more efficient, cost-effective solar generation and sharing by homeowners.
From Bitcoin to Burning Man and Beyond also introduces the path-breaking software platform that ID3 has developed called “Open Mustard Seed,” or OMS. The just-released open source program enables the rise of new types of trusted, self-healing digital institutions on open networks, which in turn will make possible new sorts of privacy-friendly social ecosystems.
“OMS is an integrated, open source package of programs that lets people collect and share personal information in secure, and transparent and accountable ways, enabling authentic, trusted social and economic relationships to flourish,” said Dr. John H. Clippinger, executive director of ID3, an acronym for the Institute for Institutional Innovation and Data-Driven Design.
“The software builds individual privacy, security and trusted exchange into the very design of the system. In effect, OMS represents a new authentication, privacy and sharing layer for the Internet,” said Clippinger “– a new way to share personal information selectively and securely, without access by unauthorized third parties.”
A two-minute video introducing the capabilities of OMS can be viewed here.”
Big Data and Chicago's Traffic-cam Scandal
Holman Jenkins in the Wall Street Journal: “The danger is microscopic regulation that we invite via the democratic process.
Big data techniques are new in the world. It will take time to know how to feel about them and whether and how they should be legally corralled. For sheer inanity, though, there’s no beating a recent White House report quivering about the alleged menace of “digital redlining,” or the use of big-data marketing tactics in ways that supposedly disadvantage minority groups.
This alarm rests on an extravagant misunderstanding. Redlining was a crude method banks used to avoid losses in bad neighborhoods even at the cost of missing some profitable transactions—exactly the inefficiency big data is meant to improve upon. Failing to lure an eligible customer into a sale, after all, is hardly the goal of any business.
The real danger of the new technologies lies elsewhere, which the White House slightly touches upon in some of its fretting about police surveillance. The danger is microscopic regulation of our daily activities that we will invite on ourselves through the democratic process.
Soon it may be impossible to leave our homes without our movements being tracked by traffic and security cameras able to read license plates, identify faces and pull up data about any individual, from social media postings to credit reports.
Private businesses are just starting to use these techniques to monitor shoppers in front of shelves of goodies. Towns and cities have already embraced such techniques as revenue grabs, encouraged by private contractors peddling automated traffic cameras.
Witness a festering Chicago scandal. This month came federal indictments of a former city bureaucrat, an outside consultant, and the former CEO of Redflex Traffic Systems, the company that operated the city’s traffic cameras until last year….”
In democracy and disaster, emerging world embraces 'open data'
Jeremy Wagstaff’ at Reuters: “Open data’ – the trove of data-sets made publicly available by governments, organizations and businesses – isn’t normally linked to high-wire politics, but just may have saved last month’s Indonesian presidential elections from chaos.
Data is considered open when it’s released for anyone to use and in a format that’s easy for computers to read. The uses are largely commercial, such as the GPS data from U.S.-owned satellites, but data can range from budget numbers and climate and health statistics to bus and rail timetables.
It’s a revolution that’s swept the developed world in recent years as governments and agencies like the World Bank have freed up hundreds of thousands of data-sets for use by anyone who sees a use for them. Data.gov, a U.S. site, lists more than 100,000 data-sets, from food calories to magnetic fields in space.
Consultants McKinsey reckon open data could add up to $3 trillion worth of economic activity a year – from performance ratings that help parents find the best schools to governments saving money by releasing budget data and asking citizens to come up with cost-cutting ideas. All the apps, services and equipment that tap the GPS satellites, for example, generate $96 billion of economic activity each year in the United States alone, according to a 2011 study.
But so far open data has had a limited impact in the developing world, where officials are wary of giving away too much information, and where there’s the issue of just how useful it might be: for most people in emerging countries, property prices and bus schedules aren’t top priorities.
But last month’s election in Indonesia – a contentious face-off between a disgraced general and a furniture-exporter turned reformist – highlighted how powerful open data can be in tandem with a handful of tech-smart programmers, social media savvy and crowdsourcing.
“Open data may well have saved this election,” said Paul Rowland, a Jakarta-based consultant on democracy and governance…”
Riding the Second Wave of Civic Innovation
Jeremy Goldberg at Governing: “Innovation and entrepreneurship in local government increasingly require mobilizing talent from many sectors and skill sets. Fortunately, the opportunities for nurturing cross-pollination between the public and private sectors have never been greater, thanks in large part to the growing role of organizations such as Bayes Impact, Code for America, Data Science for Social Good and Fuse Corps.
Indeed, there’s reason to believe that we might be entering an even more exciting period of public-private collaboration. As one local-government leader recently put it to me when talking about the critical mass of pro-bono civic-innovation efforts taking place across the San Francisco Bay area, “We’re now riding the second wave of civic pro-bono and civic innovation.”
As an alumni of Fuse Corps’ executive fellows program, I’m convinced that the opportunities initiated by it and similar organizations are integral to civic innovation. Fuse Corps brings civic entrepreneurs with experience across the public, private and nonprofit sectors to work closely with government employees to help them negotiate project design, facilitation and management hurdles. The organization’s leadership training emphasizes “smallifying” — building innovation capacity by breaking big challenges down into smaller tasks in a shorter timeframe — and making “little bets” — low-risk actions aimed at developing and testing an idea.
Since 2012, I have managed programs and cross-sector networks for the Silicon Valley Talent Partnership. I’ve witnessed a groundswell of civic entrepreneurs from across the region stepping up to participate in discussions and launch rapid-prototyping labs focused on civic innovation.
Cities across the nation are creating new roles and programs to engage these civic start-ups. They’re learning that what makes these projects, and specifically civic pro-bono programs, work best is a process of designing, building, operationalizing and bringing them to scale. If you’re setting out to create such a program, here’s a short list of best practices:
• Assets: Explore existing internal resources and knowledge to understand the history, departmental relationships and overall functions of the relevant agencies or departments. Develop a compendium of current service/volunteer programs.
• City policies/legal framework: Determine what the city charter, city attorney’s office or employee-relations rules and policies say about procurement, collective bargaining and public-private partnerships.
• Leadership: The support of the city’s top leadership is especially important during the formative stages of a civic-innovation program, so it’s important to understand how the city’s form of government will impact the program. For example, in a “strong mayor” government the ability to make definitive decisions on a public-private collaboration may be unlikely to face the same scrutiny as it might under a “council/mayor” government.
• Cross-departmental collaboration: This is essential. Without the support of city staff across departments, innovation projects are unlikely to take off. Convening a “tiger team” of individuals who are early adopters of such initiatives is important step. Ultimately, city staffers best understand the needs and demands of their departments or agencies.
• Partners from corporations and philanthropy: Leveraging existing partnerships will help to bring together an advisory group of cross-sector leaders and executives to participate in the early stages of program development.
• Business and member associations: For the Silicon Valley Talent Partnership, the Silicon Valley Leadership Group has been instrumental in advocating for pro-bono volunteerism with the cities of Fremont, San Jose and Santa Clara….”
4 things you didn't know about civic crowdfunding
That’s worth, very roughly, $1.2 billion a year worldwide per year. Within that subset, I’ve been looking at civic projects, people who are producing shared goods for a community or broader public. These projects build on histories of community fundraising and resource pooling that long predate the Internet; what’s changed is that we’ve created a scalable, portable platform model to carry out these existing practices.
So how is civic crowdfunding doing? When I started this project very few people were using that term. No one had done any aggregated data collection and published it. So I decided to take on that task. I collected data on 1224 projects between 2010 and March 2014, which raised $10.74 million in just over three years. I focused on seven platforms: Catarse (Brazil), Citizinvestor (US), Goteo (Spain), IOBY (US), Kickstarter (US), Neighbor.ly (US), and Spacehive (UK). I didn’t collect everything. There’s a new crowdfunding site every week that may or may not have a few civic projects on it. If you’re interested in my methodology, check out Chapter 2. I don’t pretend to have captured every civic project that has ever existed, but I’m working with a representative sample.
Here are four things I found out about civic crowdfunding.
- Civic crowdfunding is small-scale but relatively successful, and it has big ambitions. …
- Civic crowdfunding started as a hobby for green space projects by local non-profits, but larger organizations are getting involved. …
- Civic crowdfunding is concentrated in cities (especially those where platforms are based). …
- Civic crowdfunding has the same highly unequal distributional tendencies as other crowd markets. …”
Detroit and Big Data Take on Blight
Susan Crawford in Bloomberg View: “The urban blight that has been plaguing Detroit was, until very recently, made worse by a dearth of information about the problem. No one could tell how many buildings needed fixing or demolition, or how effectively city services were being delivered to them (or not). Today, thanks to the combined efforts of a scrappy small business, tech-savvy city leadership and substantial philanthropic support, the extent of the problem is clear.
The question now is whether Detroit has the heart to use the information to make hard choices about its future.
In the past, when the city foreclosed on properties for failure to pay back taxes, it had no sense of where those properties were clustered. The city would auction off the houses for the bargain-basement price of $500 each, but the auction was entirely undocumented, so neighbors were unaware of investment opportunities, big buyers were gaming the system, and, as often as not, arsonists would then burn the properties down. The result of this blind spot was lost population, lost revenue and even more blight.
Then along came Jerry Paffendorf, a San Francisco transplant, who saw what was needed. His company, Loveland Technologies, started mapping all the tax-foreclosed and auctioned properties. Impressed with Paffendorf’s zeal, the city’s Blight Task Force, established by President Barack Obama and funded by foundations and the state Housing Development Authority, hired his team to visit every property in the city. That led to MotorCityMapping.org, the first user-friendly collection of information about all the attributes of every property in Detroit — including photographs.
Paffendorf calls this map a “scan of the genome of the city.” It shows more than 84,000 blighted structures and vacant lots; in eight neighborhoods, crime, fires and other torments have led to the abandonment of more than a third of houses and businesses. To demolish all those houses, as recommended by the Blight Task Force, will cost almost $2 billion. Still more money will then be needed to repurpose the sites….”
Open Intellectual Property Casebook
New book by James Boyle & Jennifer Jenkins: “..This book, the first in a series of Duke Open Coursebooks, is available for free download under a Creative Commons license. It can also be purchased in a glossy paperback print edition for $29.99, $130 cheaper than other intellectual property casebooks.
This book is an introduction to intellectual property law, the set of private legal rights that allows individuals and corporations to control intangible creations and marks—from logos to novels to drug formulae—and the exceptions and limitations that define those rights. It focuses on the three main forms of US federal intellectual property—trademark, copyright and patent—but many of the ideas discussed here apply far beyond those legal areas and far beyond the law of the United States.
The book is intended to be a textbook for the basic Intellectual Property class, but because it is an open coursebook, which can be freely edited and customized, it is also suitable for an undergraduate class, or for a business, library studies, communications or other graduate school class. Each chapter contains cases and secondary readings and a set of problems or role-playing exercises involving the material. The problems range from a video of the Napster oral argument to counseling clients about search engines and trademarks, applying the First Amendment to digital rights management and copyright or commenting on the Supreme Court’s new rulings on gene patents.
Intellectual Property: Law & the Information Society is current as of August 2014. It includes discussions of such issues as the Redskins trademark cancelations, the Google Books case and the America Invents Act. Its illustrations range from graphs showing the growth in patent litigation to comic book images about copyright. The best way to get some sense of its coverage is to download it. In coming weeks, we will provide a separate fuller webpage with a table of contents and individual downloadable chapters.
The Center has also published an accompanying supplement of statutory and treaty materials that is available for free download and low cost print purchase.”
