Commentary: Sergei Khrushchev – The Cuban Missile Crisis, 50 years later

October marks the 50th anniversary of of the 13-day Cuban Missile Crisis, when President John F. Kennedy discovered that the Soviet Union was building secret missile bases in Cuba. Forgoing the option of a Cuban invasion or air strikes, Kennedy asked Russian Premier Nikita S. Khrushchev to remove all weapons from the island, and on Oct. 28, 1962, Khrushchev conceded, halting the standoff. Here, Khrushchev’s son, Sergei Khrushchev, visiting professor of Slavic languages at Brown, reflects on the diplomatic lessons.

The perspective of the crisis has changed over time and today the history of the crisis is more focused not on the confrontation, but on cooperation.

The Cuban Missile Crisis showed that two leaders decided not to shoot first, but to think and negotiate with each other. And today that is very unusual, because we think we can only negotiate with friends. Today, we impose unconditional surrender and nobody surrenders unconditionally until fully defeated. (more…)

Beyond Bieber: Twitter Improves Student Learning

EAST LANSING, Mich. — Twitter, best known as the 140-character social-networking site where Justin Bieber and Lady Gaga chit-chat with fans, has become a new literary format that is improving student learning, a new study argues.

Christine Greenhow, assistant professor of education at Michigan State University, found that college students who tweet as part of their instruction are more engaged with the course content and with the teacher and other students, and have higher grades.

“Tweeting can be thought of as a new literary practice,” said Greenhow, who also studies the growing use of social media among high-schoolers. “It’s changing the way we experience what we read and what we write.” (more…)

Shark migrations studied with underwater robot along Delmarva Peninsula

University of Delaware researchers are using an underwater robot to find and follow sand tiger sharks that they previously tagged with transmitters. The innovative project is part of a multi-year partnership with Delaware State University to better understand the behavior and migration patterns of the sharks in real time.

“In the past week our new, specially equipped glider OTIS – which stands for Oceanographic Telemetry Identification Sensor – detected multiple sand tiger sharks off the coast of Maryland that were tagged over the past several years,” said Matthew Oliver, assistant professor of oceanography in UD’s College of Earth, Ocean, and Environment. “This is the first time that a glider has found tagged sharks and reported their location in real time.” (more…)

Tablets Reinvent Americans’ Relationship with Print

Nearly 2 in 5 Tablet Owners Read Newspapers and Magazines on Their Device in August

Kindle Fire Owners Most Likely to Consume News According to comScore TabLens

RESTON, VA, October 17, 2012 – comScore, Inc., a leader in measuring the digital world, today released a study of tablet newspaper and magazine readership based on data from its comScore TabLens service. The study found that nearly 2 in 5 U.S. tablet owners read newspapers and/or magazines on their device in August, with 1 in 10 reading publications almost daily. Analysis of readership activities across platforms revealed that Kindle Fire users displayed the strongest propensity for reading newspapers and magazines on their device.

“Tablets are fundamentally redefining how people consume news and information, with the format more conducive to reading longer form content than PCs or smartphones,” said Mark Donovan, comScore SVP of Mobile. “In the case of online newspapers, tablets are now driving 7 percent of total page views, an impressive figure considering the relative infancy of the tablet space. Publishers that understand how these devices are shifting consumption dynamics will be best positioned to leverage this platform to not only drive incremental engagement among current subscribers but also attract new readers.” (more…)

New Insights into How Genetic Differences among Individuals Influence Breast Cancer Risk from Low-Dose Radiation

Berkeley Lab research could lead to new ways to ID women who have higher risk of breast cancer from low-dose radiation

Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have identified tissue mechanisms that may influence a woman’s susceptibility or resistance to breast cancer after exposure to low-dose ionizing radiation, such as the levels used in full-body CT scans and radiotherapy.

The research could lead to new ways to identify women who have higher or lower risks of breast cancer from low-dose radiation. Such a predictive tool could help guide the treatment of cancer patients who may be better served by non-radiation therapies. (more…)

IBM and Oxford Survey: Getting Closer to Customers Tops Big Data Agenda

Less than half of organizations analyzing external data; only 43 percent looking at social media for deeper understanding about consumer preferences
Lack of advanced analytics skills for tackling unstructured data biggest challenge

ARMONK, N.Y. and OXFORD – 17 Oct 2012: A new global report released today by IBM and the Saïd Business School at the University of Oxford reveals that most Big Data initiatives currently being deployed by organizations are aimed at improving the customer experience. Yet, despite the strong focus on the customer, less than half of the organizations engaged in active Big Data initiatives are currently collecting and analyzing external sources of data, like social media.

Exercise May Lead to Better School Performance for Kids with ADHD

EAST LANSING, Mich. — A few minutes of exercise can help children with attention deficit hyperactivity disorder perform better academically, according to a new study led by a Michigan State University researcher.

The study, published in the current issue of the Journal of Pediatrics, shows for the first time that kids with ADHD can better drown out distractions and focus on a task after a single bout of exercise. Scientists say such “inhibitory control” is the main challenge faced by people with the disorder. (more…)

Purpose and Uses of the Relay Board for Electronics Hobbyists and Enthusiasts

A relayboard is effectively a board containing one or more relay switches. A relay switch is often used to switch a large amount of power on for a small operating energy; or to turn specific circuits on and off within an application.

Often the relay becomes the breaker point between a low and high voltage, or a low and high current, part of an application. The most obvious version of this usage is the RCD board used to insulate your home against electrical surges. The trip switches on the board are all relays – in effect making the RCD (otherwise known as a residual current device) one of the largest and most obvious relay boards in the country. (more…)
