Twitter analysis shows Boston bombings had little effect on immigration reform conversations

2013-05-08
(Press-News.org) An analysis by researchers at the Institute for Immigration Research (IIR) at George Mason University shows that the Boston Marathon bombings had little effect on conversations on social media regarding immigration reform.

Using two different data mining applications, the researchers collected more than 750,000 tweets containing the word "immigration" beginning in February 2013.

"The Boston Marathon bombings on April 15, 2013 provided an unexpected opportunity to examine how this event has affected the immigration reform debate," says Jim Witte, director of the IIR. "We compared conversations about immigration on Twitter before, during, and after April 15."

Before the bombing, Witte says, conversations on Twitter were very polarized—with separate conservative and liberal clusters not interacting much with each other in conversation. Another cluster of users talking about immigration included more diversity. "It's best described as a mainstream cluster that includes both liberal as well as conservative viewpoints," says Witte. "These tweeters tend not to be as extreme, and they have many connections with the two more ideological clusters, which suggests that this the mainstream cluster acts in part as an informational bridge between them."

On the day of the Boston bombings, the conversation on Twitter shifted a little, the researchers saw. "Tweeters in all clusters were tweeting about the bombing in relation to immigration—even though there was not yet any evidence of such a connection," says Witte. The conservative cluster diminished in size and there was a large influx of tweeters who weren't connected to any other immigration tweeters.

With evidence that Chechnyan immigrants Tamerlan and Dzhokhar Tsarnaev were responsible for the Boston Marathon bombing, mainstream media were speculating whether their status might affect the immigration debate in America. Words like "deportation," "amnesty," "terrorism," and "borders" were associated with immigration tweets after the bombings.

However, just two weeks after the bombing, Witte says, the conversations looked very similar to those before the bombings took place. "In the short run, we found no indication that this connection has left a permanent mark on the conversation on Twitter," Witte says.

Witte says that tracking these conversations via social media is important not only to look at the progress of issues like immigration reform but also to understand the relationship between social media and public opinion.

AFOSR-funded research key to revolutionary 'green' spacecraft propellant

2013-05-08
In 2015, NASA, for the first time, will fly a space mission utilizing a radically different propellant—one which has reduced toxicity and is environmentally benign. This energetic ionic liquid, or EIL, is quite different from the historically employed hydrazine-based propellant, which was first used as a rocket fuel during World War II for the Messerschmitt Me 163B (the first rocket-powered fighter plane). Within the U.S. space program, hydrazine was used on the 1970s Viking Mars program, and more recently in the Phoenix lander and Curiosity rover Mars missions, as ...

Duke researchers describe how breast cancer cells acquire drug resistance

2013-05-08
DURHAM, N.C. -- A seven-year quest to understand how breast cancer cells resist treatment with the targeted therapy lapatinib has revealed a previously unknown molecular network that regulates cell death. The discovery provides new avenues to overcome drug resistance, according to researchers at Duke Cancer Institute. "We've revealed multiple new signaling pathways that regulate cell death," said Sally Kornbluth, PhD, vice dean of Basic Science and professor of Pharmacology and Cancer Biology at Duke University School of Medicine. "And we've shown, at least in one disease, ...

Turning Alzheimer's fuzzy signals into high definition

Scientists at the Virginia Tech Carilion Research Institute have discovered how the predominant class of Alzheimer's pharmaceuticals might sharpen the brain's performance One factor even more important than the size of a television screen is the quality of the signal it displays. Having a life-sized projection of Harry Potter dodging a Bludger in a Quidditch match is of little use if the details are lost to pixilation. The importance of transmitting clear signals, however, is not relegated to the airwaves. The same creed applies to the electrical impulses navigating ...

New robotic instruments to provide real-time data on Gulf of Maine red tide

2013-05-08
A new robotic sensor deployed by Woods Hole Oceanographic Institution (WHOI) in Gulf of Maine coastal waters may transform the way red tides or harmful algal blooms (HABs) are monitored and managed in New England. The instrument was launched at the end of last month, and a second such system will be deployed later this spring. The results will add critical data to weekly real-time forecasts of New England red tide this year distributed to more than 150 coastal resource and fisheries managers in six states as well as federal agencies such as NOAA, the FDA and the EPA. ...

UF launches HiPerGator, the state's most powerful supercomputer

2013-05-08
GAINESVILLE, Fla. — The University of Florida today unveiled the state's most powerful supercomputer, a machine that will help researchers find life-saving drugs, make decades-long weather forecasts and improve armor for troops. The HiPerGator supercomputer and recent tenfold increase in the size of the university's data pipeline make UF one of the nation's leading public universities in research computing. "If we expect our researchers to be at the forefront of their fields, we need to make sure they have the most powerful tools available to science, and HiPerGator ...

Salk scientists find potential therapeutic target for Cushing's disease

2013-05-08
LA JOLLA, CA---Scientists at the Salk Institute for Biological Studies have identified a protein that drives the formation of pituitary tumors in Cushing's disease, a development that may give clinicians a therapeutic target to treat this potentially life-threatening disorder. The protein, called TR4 (testicular orphan nuclear receptor 4), is one of the human body's 48 nuclear receptors, a class of proteins found in cells that are responsible for sensing hormones and, in response, regulating the expression of specific genes. Using a genome scan, the Salk team discovered ...

Study links diet with daytime sleepiness and alertness in healthy adults

2013-05-08
DARIEN, IL – A new study suggests that your level of sleepiness or alertness during the day may be related to the type of food that you eat. Results show that higher fat consumption was associated with increased objective daytime sleepiness, while higher carbohydrate intake was associated with increased alertness. There was no relationship between protein consumption and sleepiness or alertness. These findings were independent of the subjects' gender, age, and body mass index as well as the total amount of sleep they were getting and their total caloric intake. "Increased ...

Study shows that bedtime regularity predicts CPAP compliance

2013-05-08
DARIEN, IL – A new study suggests that regularity of bedtime prior to initiation of continuous positive airway pressure (CPAP) therapy is an important factor that may influence treatment compliance in adults with obstructive sleep apnea (OSA). Results show that bedtime variability was a significant predictor of CPAP adherence, which was defined as four or more hours of treatment use per night. The odds of one-month CPAP non-adherence were 3.7 times greater for every one unit increase in habitual, or pre-treatment, bedtime variability. "Long-term use of CPAP, such as ...
