Build your online networks using social annotations

2011-02-17
(Press-News.org) Researchers at Toshiba are working on a way of finding clusters of like-minded bloggers and others online using "social annotations". Social annotations are the tags and keywords, the comments and feedback that users, both content creators and others associate with their content. Their three-step approach could help you home in on people in a particular area of expertise much more efficiently and reliably than simply following search engine results. The same tools might also be used in targeted marketing.

Users of photo gallery sites, such as Flickr (http://www.flickr.com/) and the social bookmarking sites like Delicious (http://delicious.com/) are familiar with social annotations. These services offer environments in which social annotations can be assigned with precision to different digital objects, whether a photograph, a bookmark, or more widely to blog posts, video uploads and discussion threads. With such annotations in place - notes and tags - users can easily search pictures or bookmarks. Toshiba's Shigeaki Sakurai and Hideki Tsutsui currently at Tokyo company NewsWatch suggest that the same social annotations could also be used to build networks.

It is relatively easy to create keyword-rich social annotations, the researchers explain, and such annotations represent an additional layer of knowledge concerning the digital objects with which they are associated. Previous researchers have considered how social annotations might be used to improve search engine results and how web pages might be automatically tagged based on such annotations.

The team explains that their technique allows them to divide bloggers into clusters according to their interests. The method calculates similarities between bloggers based on three steps: First it identifies target objects (subjects of interest), secondly it calculates similarities between target objects discussed in blog articles based on social annotations, and thirdly it calculates how these target objects are rated based on impression words in the blog posts. Products and services are considered the target objects in their study, which was tested on data from Commutents and the Yahoo Japan Movie services. These three steps are then combined to create cluster of bloggers.

Water softeners not found to improve childhood eczema

2011-02-17
The first study of its kind in the world — involving 336 children aged between six months and 16 years old — has shown that installing a water softener for three months brings no additional relief for eczema sufferers. Up to one fifth of all children of school age have eczema, along with about one in 12 of the adult population. Anecdotal reports from patients have suggested that hard water may worsen atopic eczema. Population surveys have also suggested a possible link between atopic eczema prevalence and the degree of water hardness. It had been hoped that water softeners ...

Treatment for manic-depressive illness restores brain volume deficits

2011-02-17
Philadelphia, PA, 16 February 2011 - Lithium, introduced in the late 1940's, was the first "wonder drug" in psychiatry. It was the first medication treatment for the manic and depressive episodes of bipolar disorder and it remains among one of the most effective treatments for this disorder. In the past 15 years, as molecular mechanisms underlying the treatment of bipolar disorder began to emerge, basic research studies conducted in animals began to identify neuroprotective and perhaps neurotrophic effects of this important medication. The identification of these ...

Study looks into evolution of breast cancer in Spain

2011-02-17
Pioneering Spanish provinces in terms of early prevention of breast cancer, such as Navarre and the Basque Country, record lower death rates, although the trend is towards the figures levelling out all over Spain. These are the results of a study carried out by Spanish researchers, which analyses the number of women who died between 1975 and 2005. "The Canary Islands, Balearic Islands, some parts of Catalonia, Valencia and Murcia, as well as the south west region, have higher breast cancer death rates, although there is a trend towards the geographical differences disappearing", ...

President Obama's 2012 budget: Nation's future depends on science, innovation

2011-02-17
WASHINGTON—February 16, 2011— Research!America's board chair, former Congressman John Edward Porter, and president, Mary Woolley, thanked President Obama for prioritizing medical, health and scientific research in his FY2012 budget proposal. The president's budget includes $31.829 billion for the National Institutes of Health ($745 million increase over 2010); $7.8 billion for the National Science Foundation ($1.2 billion increase over 2010); and $2.747 billion for the Food and Drug Administration ($382 million increase over 2010). The budget proposes $5.8 billion for ...

Finding a way to extend tomato shelf-life

2011-02-17
Tomatoes spend so much time on shelves and in refrigerators that an estimated 20 percent are lost to spoilage, according to the U.S. Department of Agriculture (USDA). But scientists with USDA's Agricultural Research Service (ARS) are working with colleagues at Purdue University to extend the shelf life of tomatoes. The research also may lead to tomatoes that taste better and are more nutritious. ARS is USDA's principal intramural scientific research agency, and the research results support the USDA priority of promoting international food security. Autar Mattoo, a ...

Running on a faster track

2011-02-17
What matters for commuters is not just if the train will be on time, but how long the journey will take. It's an important factor in public transportation and can make the difference in helping commuters choose mass transit over more polluting and costly transport like cars or airplanes. Dr. Tal Raviv and his graduate student Mor Kaspi of Tel Aviv University's Department of Industrial Engineering in the Iby and Aladar Fleischman Faculty of Engineering have developed a tool that makes passenger train journeys shorter, especially when transfers are involved — a computer-based ...

Smoking during radiation treatments reduces chance of overall survival

2011-02-17
Smokers who continue to smoke while undergoing radiation treatments for head and neck cancer fare significantly worse than those who quit smoking before therapy, according to a study in the February issue of the International Journal of Radiation Oncology•Biology•Physics, an official journal of the American Society for Radiation Oncology (ASTRO). Although the association between tobacco smoking and head and neck cancers has long been established, there had been little data until now showing whether continued smoking during treatment affects prognosis. "I've always ...

Innovative virtual reality exposure therapy shows promise for returning troops

2011-02-17
TACOMA, WA —February 16, 2011— An article published in a forthcoming issue of the Journal of Traumatic Stress is one of the first to provide evidence of the effectiveness of exposure therapy with active duty military service members suffering from posttraumatic stress disorder (PTSD). The study shows that virtual reality exposure therapy resulted in significant reductions in PTSD symptoms after an average of seven treatment sessions. Additionally, 62 % of patients reported clinically meaningful, reliable change in PTSD symptoms. During the treatment the soldier repeatedly ...

Dial 5683 for love: Dialing certain numbers on a cell phone changes your emotional state

2011-02-17
A psychological scientist in Germany has found a way that cell phones, and specifically texting, have hacked into our brains. Just by typing the numbers that correspond to the letters in a word like "love," we can activate the meaning of that word in our minds. The results are published in Psychological Science, a journal of the Association for Psychological Science. For the study, Sascha Topolinski and his students at the University of Würzburg in Germany created a list of German words that can be typed on a cell phone keypad without typing the same digit twice in a ...

Latino siblings of children with developmental disabilities at risk

2011-02-17
EAST PROVIDENCE, R.I. – Latino siblings of children developmental disabilities such as Down syndrome and autism may face their own challenges, including anxiety and lower school performance, according to a new study led by researchers with the Bradley Hasbro Children's Research Center. "When a child has a disability, all members of the family are affected, including siblings," said lead author Debra Lobato, Ph.D., of the Bradley Hasbro Children's Research Center. "However, little attention has been paid to the influence of cultural factors on the functioning of siblings. ...
