A selfie is a type of self-portrait photograph, typically taken with a hand-held digital camera or camera phone, and are usually taken in a slightly tilted maner. Selfies are often associated with social networking. In the Korean entertainment industry the word selca (short for "self camera") means photos taken of oneself.
Colin Meyn explains how the ‘rapid spread of social media is altering Cambodia’s political landscape.’ The young electorate desirous of change plus the aggressive campaigning of the opposition in the Internet made a huge impact in...
"We’ve been able to process and make sense of a quarter of a million tweets in the aftermath of Typhoon Yolanda. Using both AIDR (still under development) andTwitris, we were able to collect these tweets in real-time and use automated algorithms to filter for both relevancy and uniqueness. The resulting ~55,000 tweets were then uploaded to MicroMappers (still under development). Digital volunteers from the world over used this humanitarian technology platform totag tweets and now images from the disaster (click image below to enlarge). At one point, volunteers tagged some 1,500 tweets in just 10 minutes. In parallel, we used machine learning classifiers to automatically identify tweets referring to both urgent needs and offers of help. In sum, the response to Typhoon Yolanda is the first to make full use of advanced computing, i.e., both human computing and machine computing to make sense of Big (Crisis) Data"
The Science as an open enterprise report highlights the need to grapple with the huge deluge of data created by modern technologies in order to preserve the principle of openness and to exploit data in ways that have the potential to create a second open science revolution.
Exploring massive amounts of data using modern digital technologies has enormous potential for science and its application in public policy and business. The report maps out the changes that are required by scientists, their institutions and those that fund and support science if this potential is to be realised.
Areas for action
Six key areas for action are highlighted in the report:
Scientists need to be more open among themselves and with the public and media
Greater recognition needs to be given to the value of data gathering, analysis and communication
Common standards for sharing information are required to make it widely usable
Publishing data in a reusable form to support findings must be mandatory
More experts in managing and supporting the use of digital data are required
New software tools need to be developed to analyse the growing amount of data being gathered
"In this book, I suggest that to understand cities we must view them not simply as places in space but as systems of networks and flows. To understand space, we must understand flows, and to understand flows, we must understand networks—the relations between objects that comprise the system of the city. Drawing on the complexity sciences, social physics, urban economics, transportation theory, regional science, and urban geography, , I introduce theories and methods that reveal the deep structure of how cities function.
