Going viral: How ‘social contagion’ begins and escalates

Understanding the roots of a global, contagious spread of online information may help better predict political revolutions, consumer behavior, box office revenues, public policy debates, and even public health epidemics, a new study co-led by Yale University reveals. The model devised for this study, which identifies those roots and analyzes common patterns of dissemination on a global scale, even predicted the rise of “#Obamacare” as a global Twitter trend. The study appears in PLOS ONE.

Attempts to globally monitor the spread of online information have become increasingly difficult because of the explosive growth in the amount of information available and heightened concerns about personal privacy. To get a better understanding of social contagion, the team focused instead on smaller, local network structures, where messages are transmitted from individuals at the center and spread out rapidly to other individuals, who then retransmit them.

Privatheit – Wie viel ist davon noch übrig?

Datenschutz, Kontrollen und die Frage nach der Privatsphäre werden besonders seit den Abhörskandalen wieder stark diskutiert. Anne Siegetsleitner, Professorin für Praktische Philosophie, fragt sich, wie mit Privatheit persönlich und gesellschaftlich umgegangen werden soll, was noch gerettet werden kann oder ob in dieser Hinsicht schon alles verloren ist.

Vor allem im Zusammenhang mit neuen Informations- und Kommunikationstechnologien oder den brisanten Enthüllungen von Edward Snowden gerieten Fragen nach dem Umgang mit Privatheit in den Fokus der medialen Aufmerksamkeit. Besonders soziale Netzwerke wie Facebook, das etwa 1,26 Milliarden Mitglieder zählt, gerieten in das Kreuzfeuer der Datenschützer und Datenschützerinnen. Doch nicht nur in solchen Kommunikationskanälen geben Menschen Informationen über sich preis. Auch via E-Mail, in Suchmaschinen oder Diensten wie WhatsApp hinterlassen die Nutzerinnen und Nutzer ihre Spuren. Facebook gilt neben Google und Amazon als eine der großen Datenbanken im Internet – und diese Informationsspeicher polarisieren. (more…)

‘Melbourne Shuffle’ secures cloud data

Encryption might not be enough for all that data stored in the cloud. An analysis of usage patterns — which files are accessed and when — can give away secrets as well. Computer scientists at Brown have developed an algorithm to sweep away those digital footprints. It’s a complicated series of dance-like moves they call the Melbourne Shuffle.

PROVIDENCE, R.I. [Brown University] — To keep data safe in the cloud, a group of computer scientists suggests doing the Melbourne Shuffle. (more…)

Interviews with Over 500 CMOs Show Data, Social Media Present Biggest Opportunities and Challenges

Armonk, N.Y. – 17 Mar 2014: According to a new IBM study, high-performing CMOs are integrating internal and external data to garner deep insights that, in turn, provide them with a much deeper understanding of their customers.

The study, entitled “Stepping up to the challenge: How CMOs can start to close the aspirational gap,” is based on findings from face-to-face conversations with more than 500 CMOs from 56 countries and 19 industries worldwide. Conducted by IBM’s Institute for Business Value (IBV), the study reveals that 94 percent of CMOs believe advanced analytics will play a significant role in helping them reach their goals. However, an increased number of CMOs say their organizations are underprepared to capitalize on the data explosion – 82 percent compared to 71 percent three years before. (more…)

Study of more than 1,600 CIOs adds customer satisfaction to the tech executives’ performance review

ARMONK, N.Y. – 13 Mar 2014: With consumers engaging more directly with businesses through mobile and social media, more than 60 percent of CIOs will focus more heavily on improving the customer experience and getting closer to customers, according to a new report released by IBM.

The report, entitled “Moving from the Back Office to the Front Lines – CIO Insights from the Global C-suite Study” is based on face-to-face conversations with more than 1,600 CIOs from 70 countries and 20 industries worldwide. The research, conducted by IBM’s Institute for Business Value, reveals that customers drive CIOs to turn their focus to the front lines. (more…)

UCLA researchers create Google Glass app for instant medical diagnostic test results

A team of researchers from UCLA’s Henry Samueli School of Engineering and Applied Science has developed a Google Glass application and a server platform that allow users of the wearable, glasses-like computer to perform instant, wireless diagnostic testing for a variety of diseases and health conditions.

With the new UCLA technology, Google Glass wearers can use the device’s hands-free camera to capture pictures of rapid diagnostic tests (RDTs), small strips on which blood or fluid samples are placed and which change color to indicate the presence of HIV, malaria, prostate cancer or other conditions. Without relying on any additional devices, users can upload these images to a UCLA-designed server platform and receive accurate analyses — far more detailed than with the human eye — in as little as eight seconds.

New Technique Targets C Code to Spot, Contain Malware Attacks

Researchers from North Carolina State University have developed a new tool to detect and contain malware that attempts root exploits in Android devices. The tool improves on previous techniques by targeting code written in the C programming language – which is often used to create root exploit malware, whereas the bulk of Android applications are written in Java.

Root exploits take over the system administration functions of an operating system, such as Android. A successful Android root exploit effectively gives hackers unfettered control of a user’s smartphone. (more…)

Berkeley Lab Startup Wants to Know How Damaged Your DNA Is

Exogen can check the DNA health not only of an individual but that of an entire region, thus answering questions on the impact of environmental events.

Currently if a scientist or doctor wanted to measure the level of a person’s DNA damage, they would have to look at some cells in a fluorescent microscope and manually count the number of DNA breaks. This kind of counting is labor-intensive, time-consuming, and a highly subjective process. Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Sylvain Costes, who has spent over a decade studying the effects of low-dose radiation on cellular processes, came up with a way to automate the job using a proprietary algorithm and a machine to scan specimens and objectively score the damaged DNA.
