Mapping the Twitterverse

Phys.org: “What does your Twitter profile reveal about you? More than you know, according to Chris Weidemann. The GIST master’s student has developed an application that follows geospatial footprints.
You start your day at your favorite breakfast spot. When your order of strawberry waffles with extra whipped cream arrives, it’s too delectable not to share with your Twitter followers. You snap a photo with your smartphone and hit send. Then, it’s time to hit the books.
You tweet your friends that you’ll be at the library on campus. Later that day, palm trees silhouette a neon-pink sunset. You can’t resist. You tweet a picture with the hashtag #ILoveLA.
You may not realize that when you tweet those breezy updates and photos of food, you are sharing information about your location.
Chris Weidemann, a graduate student in the Geographic Information Science and Technology (GIST) online master’s program at USC Dornsife, investigated just how much public was generated by Twitter users and how their information—available through Twitter’s (API)—could potentially be used by third parties. His study was published June 2013 in the International Journal of Geoinformatics…
Twitter has approximately 500 million active users, and reports show that 6 percent of users opt-in to allow the platform to broadcast their location using global positioning technology with each tweet they post. That’s about 30 million people sending geo-tagged data out into the Twitterverse. In their tweets, people can choose whether their information is displayed as a city and state, an address or pinpoint their precise latitude and longitude.
That’s only part of their geospatial footprint. Information contained in a post may reveal a user’s location. Depending upon how the account is set up, profiles may include details about their hometown, time zone and language.”
 

Linux Foundation Collaboration Gets Biological

Curated on Posted on by Stefaan Verhulst

eWeek: “The Linux Foundation is growing its roster of collaboration projects by expanding from the physical into the biological realm with the OpenBEL (Biological Expression Language). The Linux Foundation, best known as the organization that helps bring Linux vendors and developers together, is also growing its expertise as a facilitator for collaborative development projects…
OpenBEL got its start in June 2012 after being open-sourced by biotech firm Selventa. The effort now includes the participation of Foundation Medicine, AstraZeneca,The Fraunhofer Institute, Harvard Medical School, Novartis, Pfizer and the University of California at San Diego.
BEL offers researchers a language to clearly express scientific findings from the life sciences in a format that can be understood by computing infrastructure…..
The Linux Foundation currently hosts a number of different collaboration projects, including the Xen virtualization project, the OpenDaylight software-defined networking effort, Tizen for mobile phone development, and OpenMAMA for financial services information, among others.
The OpenBEL project will be similar to existing collaboration projects in that the contributors to the project want to accelerate their work through collaborative development, McPherson explained.”

Government Is a Good Venture Capitalist

Curated on Posted on by Stefaan Verhulst

Wall Street Journal: “In a knowledge-intensive economy, innovation drives growth. But what drives innovation? In the U.S., most conservatives believe that economically significant new ideas originate in the private sector, through either the research-and-development investments of large firms with deep pockets or the inspiration of obsessive inventors haunting shabby garages. In this view, the role of government is to secure the basic conditions for honest and efficient commerce—and then get out of the way. Anything more is bound to be “wasteful” and “burdensome.”
The real story is more complex and surprising. For more than four decades, R&D magazine has recognized the top innovations—100 each year—that have moved past the conceptual stage into commercial production and sales. Economic sociologists Fred Block and Matthew Keller decided to ask a simple question: Where did these award-winning innovations come from?
The data indicated seven kinds of originating entities: Fortune 500 companies; small and medium enterprises (including startups); collaborations among private entities; government laboratories; universities; spinoffs started by researchers at government labs or universities; and a grab bag of other public and nonprofit agencies.
Messrs. Block and Keller randomly selected three years in each of the past four decades and analyzed the resulting 1,200 innovations. About 10% originated in foreign entities; the sociologists focused on the domestic innovations, more than 1,050.
Two of their findings stand out. First, the number of award winners originating in Fortune 500 companies—either working alone or in collaboration with others—has declined steadily and sharply, from an annual average of 44 in the 1970s to only nine in the first decade of this century.
Second, the number of top innovations originating in federal laboratories, universities or firms formed by former researchers in those entities rose dramatically, from 18 in the 1970s to 37 in the 1980s and 55 in the 1990s before falling slightly to 49 in the 2000s. Without the research conducted in federal labs and universities (much of it federally funded), commercial innovation would have been far less robust…”

Twitter’s activist roots: How Twitter’s past shapes its use as a protest tool

Curated on Posted on by Stefaan Verhulst

Radio Netherlands Worldwide: “Surprised when demonstrators from all over the world took to Twitter as a protest tool? Evan “Rabble” Henshaw-Plath, member of Twitter’s founding team, was not. Rather, he sees it as a return to its roots: Inspired by protest coordination tools like TXTMob, and shaped by the values and backgrounds of Twitter’s founders, he believes activist potential was built into the service from the start.

It took a few revolutions before Twitter was taken seriously. Critics claimed that its 140-character limit only provided space for the most trivial thoughts: neat for keeping track of Ashton Kutcher’s lunch choices, but not much else. It made the transition from Silicon Valley toy into Middle East protest tool seem all the more astonishing.
Unless, Twitter co-founder Evan Henshaw-Plath argues, you know the story of how Twitter came to be. Evan Henshaw-Plath was the lead developer at Odeo, the company that started and eventually became Twitter. TXTMob, an activist tool deployed during the 2004 Republican National Convention in the US to coordinate protest efforts via SMS was, says Henshaw-Plath, a direct inspiration for Twitter.
Protest 1.0
In 2004, while Henshaw-Plath was working at Odeo, he and a few other colleagues found a fun side-project in working on TXTMob, an initiative by what he describes as a “group of academic artist/prankster/hacker/makers” that operated under the ostensibly serious moniker of Institute for Applied Autonomy (IAA). Earlier IAA projects included small graffiti robots on wheels that spray painted slogans on pavements during demonstrations, and a pudgy talking robot with big puppy eyes made to distribute subversive literature to people who ignored less-cute human pamphleteers.
TXTMob was a more serious endeavor than these earlier projects: a tactical protest coordination tool. With TXTMob, users could quickly exchange text messages with large groups of other users about protest locations and police crackdowns….”

The Multistakeholder Model in Global Technology Governance: A Cross-Cultural Perspective

Curated on Posted on by Stefaan Verhulst

New APSA 2013 Annual Meeting Paper by Nanette S. Levinson: “This paper examines two key but often overlooked analytic dimensions related to global technology governance: the roles of culture and cross-cultural communication processes and the broader framework of Multistakeholderism. Each of these dimensions has a growing tradition of research/conceptual frameworks that can inform the analysis of Internet governance and related complex and power-related processes that may be present in a multistakeholder setting. The use of the term ‘multistakeholder’ itself has grown exponentially in discussing Internet governance and related governance domains; yet there are few rigorous studies within Internet governance that treat actual multistakeholder processes, especially from a cross-cultural and comparative perspective.
Using research on cross-cultural communication and related factors (at small group, occupational, organizational, interorganizational or cross- sector, national, regional levels), this paper provides and uses an analytic framework, especially for the 2012 WCIT and 2013 WSIS 10 and World Telecommunications Policy Forum that goes beyond the rhetoric of ‘multistakeholder’ as a term. It includes an examination of variables found to be important in studies from environmental governance, public administration, and private sector partnership domains including trust, absorptive capacity, and power in knowledge transfer processes. “

AeroSee: Crowdsourcing Rescue using Drones

Curated on Posted on by Stefaan Verhulst

“The AeroSee experiment is an exciting new project where you can become a virtual mountain rescue assistant from the comfort of your own home, simply by using your computer. Every year Patterdale Mountain Rescue assist hundreds of injured and missing persons from around the Ullswater area in the North of the Lake District. The average search takes several hours and can require a large team of volunteers to set out in often poor weather conditions. This experiment is to see how the use of UAV (or ‘Drone’) technology, together with your ‘crowd-sourced’ help can reduce the time taken to locate and rescue a person in distress.
Civilian Use of UAVs
Here at UCLan we are interested in investigating the civilian applications of unmanned systems. They offer a rich and exciting source of educational and research material for our students and research staff. As regulations for their use are being developed and matured by aviation authorities, it is important that research is conducted to maximise their benefits to society.
Our Partners
We are working with e-Migs, a light-UAV operator who are providing and operating the aircraft during the search.
How aeroSee Works
infographic
Upon receiving a rescue call the Mountain Rescue services plan their search area and we dispatch our unmanned remotely piloted aircraft to begin a search for the missing persons. Using a real time video link, the aircraft transmits pictures of terrain to our website where you can help by viewing the images and tagging the photos if you spot something that the Mountain Rescue services need to investigate, such as a possible sighting of an injured party. We use some computer algorithms to process the tagged data that we receive and pass this processed data onto the Mountain Rescue Control Centre for a final opinion and dispatch of search teams.
We believe this approach can reduce time and save lives and we need your help to prove it. Once you are signed up, you can practice using the site by choosing ‘Practice Mission’ from the menubar. Fancy yourself as a Virtual Search agent? If have not already done so, sign up here:

Weather Channel Now Also Forecasts What You'll Buy

Curated on Posted on by Stefaan Verhulst

Katie Rosman int the Wall Street Journal: “The Weather Channel knows the chance for rain in St. Louis on Friday, what the heat index could reach in Santa Fe on Saturday and how humid Baltimore may get on Sunday.
It also knows when you’re most likely to buy bug spray.
The enterprise is transforming from a cable network viewers flip to during hurricane season into an operation that forecasts consumer behavior by analyzing when, where and how often people check the weather. Last fall the Weather Channel Cos. renamed itself the Weather Co. to reflect the growth of its digital-data business.

The Atlanta-based company has amassed more than 75 years’ worth of information: temperatures, dew points, cloud-cover percentages and much more, across North America and elsewhere.
The company supplies information for many major smartphone weather apps and has invested in data-crunching algorithms. It uses this analysis to appeal to advertisers who want to fine-tune their pitches to consumers….
Weather Co. researchers are now diving into weather-sentiment analysis—how local weather makes people feel, and then act—in different regions of the country. To cull this data, Mr. Walsh’s weather-analytics team directly polls visitors to the Weather.com website, asking them about their moods and purchases on specifics days.
In a series of polls conducted between June 3 and Nov. 4 last year, residents of the Northeast region responded to the question, “Yesterday, what was your mood for most of the day?”

Big Data and Disease Prevention: From Quantified Self to Quantified Communities

Curated on Posted on by Stefaan Verhulst

New Paper by Meredith A. Barrett, Olivier Humblet, Robert A. Hiatt, and Nancy E. Adler: “Big data is often discussed in the context of improving medical care, but it also has a less appreciated but equally important role to play in preventing disease. Big data can facilitate action on the modifiable risk factors that contribute to a large fraction of the chronic disease burden, such as physical activity, diet, tobacco use, and exposure to pollution. It can do so by facilitating the discovery of risk factors for disease at population, subpopulation, and individual levels, and by improving the effectiveness of interventions to help people achieve healthier behaviors in healthier environments. In this article, we describe new sources of big data in population health, explore their applications, and present two case studies illustrating how big data can be leveraged for prevention. We also discuss the many implementation obstacles that must be overcome before this vision can become a reality.”

A promising phenomenon of open data: A case study of the Chicago open data project

Curated on Posted on by Stefaan Verhulst

Paper by Maxat Kassen in Government Information Quarterly: “This article presents a case study of the open data project in the Chicago area. The main purpose of the research is to explore empowering potential of an open data phenomenon at the local level as a platform useful for promotion of civic engagement projects and provide a framework for future research and hypothesis testing. Today the main challenge in realization of any e-government projects is a traditional top–down administrative mechanism of their realization itself practically without any input from members of the civil society. In this respect, the author of the article argues that the open data concept realized at the local level may provide a real platform for promotion of proactive civic engagement. By harnessing collective wisdom of the local communities, their knowledge and visions of the local challenges, governments could react and meet citizens’ needs in a more productive and cost-efficient manner. Open data-driven projects that focused on visualization of environmental issues, mapping of utility management, evaluating of political lobbying, social benefits, closing digital divide, etc. are only some examples of such perspectives. These projects are perhaps harbingers of a new political reality where interactions among citizens at the local level will play an more important role than communication between civil society and government due to the empowering potential of the open data concept.”
