Minority of Twitter users responsible for vast majority of political tweets
Associate Professor of Law David Levine recently lent his expertise to a Washington Post article looking at who is posting tweets about U.S. politics on the popular social media platform. The Oct. 24 article by reporter Marie Baca examined a recent report by the Pew Research Center that found that 10 percent of U.S. adult Twitter users generated 97 percent of tweets mentioning national politics. Those who were most prolific accounted for just 6 percent of all U.S. adult Twitter users, but authored 73 percent of all political tweets, the report found. "It can be quite dangerous if you’re not taking a step back and saying, ‘What do I know about the sources of this information and who or what is behind it?’” — David Levine, associate professor of law Levine, who is the founder of the "Hearsay Culture" radio show about modern technology issues, noted that Twitter users who find themselves in an echo chamber populated by others who mirror their views could take less time to determine the origin or assess the truthfulness of information they receive in that chamber. “It can be quite dangerous if you’re not taking a step back and saying, ‘What do I know about the sources of this information and who or what is behind it?’” he said. “It’s very easy psychologically, especially if you’re coming into it with a particular perspective, to go along with it.” If Professor Levine can assist with your reporting about social media and online extremism, please reach out to Owen Covington, director of the Elon University News Bureau, at ocovington@elon.edu or (336) 278-7413.

2020 is the goal for launching 5G, a collection of technologies that is expected to increase cellular technology worldwide by 1,000 times the capacity, 100 times more devices and 10 times less delay. “5G is about connecting everything everywhere, anything you can imagine,” says Mojtaba Vaezi, PhD, assistant professor of electrical and computer engineering at Villanova’s College of Engineering, whose area of expertise is wireless communication, signal processing and information and communication technology. Partly because of our changing habits there are applications that will need higher speed, and 5G will increase their capacity. “We’re consuming more and more data these days, so we need higher volume of data. The new generation watches TV online and plays games online. They want to select whatever they like and download it when they want it,” says Dr. Vaezi. “The speed of communication is going to increase about 10 to 20 times, so if it takes one minute to download a movie in your cell phone today, in a few years we’ll be able to download a movie in three to six seconds.” 4G technology has mostly been about connecting cell phones, but 5G will be about connecting all kinds of devices: Cars will be able to connect to other cars, traffic lights and cell phones; customers ordering online will be able to track their package as it travels across the ocean; trucks will connect to each other, sharing information such as if a route needs to be changed. There are many applications, from driverless cars to surgeries on a patient in one country done remotely by a doctor in another country, connecting thousands of miles away in just a fraction of seconds. There are always challenges associated with new technology, however. In particular, 5G researchers worldwide have been working for a decade to increase the capacity and number of connections foreseen for 5G networks. In 4G and previous generations, each cell phone would transmit in distance frequencies, otherwise they’d interfere with each other. In 5G and beyond, cell phones may share their frequencies with other cell phones or devices, or we wouldn’t be able to accommodate the exploding number of new devices. This will introduce inter-device interference which is a challenge. Now, we have two or four antennas packed inside the phone. Soon, mobile towers and cell phones will have tens of antennas, further increasing capacity.
Facebook Buys Startup Building Neural Monitoring Armband
Facebook has talked a lot about working on a non-invasive brain input device that can make things like text entry possible just by thinking. So far, most of the company’s progress on that project appears to be taking the form of university research that they’ve funded. With this acquisition, the company appears to be working more closely with technology that could one day be productized. Circuit Seed for continuous analog signal processing and Corelogika for discrete digital logic could greatly enhance the success of commercialization of Armband. These are building blocks to build low power high performance circuits that result in products that are smaller, very low power consumption, increased sensitivity and accuracy and they are insensitive to process variation and temperature that are challenges for other devices. Since they use standard CMOS digital processes with no extensions, the designs are less complex, fewer bill of materials resulting in lower cost, higher yields and better margins.

How are Governments Using Artficial Intelligence? How are They Misusing AI?
There has been a lot of talk about artificial intelligence – who is using it, how it works, and what it will lead to. Rensselaer Polytechnic Institute professor James Hendler – who was recently named to the newly formed Association for Computing Machinery (ACM) Technology Policy Council – penned a piece for The Conversation outlining the danger A.I. could pose to American society if there is not enough oversight. Here are some excerpts: “Artificial intelligence systems can – if properly used – help make government more effective and responsive, improving the lives of citizens. Improperly used, however, the dystopian visions of George Orwell’s “1984” become more realistic. On their own and urged by a new presidential executive order, governments across the U.S., including state and federal agencies, are exploring ways to use AI technologies. As an AI researcher for more than 40 years, who has been a consultant or participant in many government projects, I believe it’s worth noting that sometimes they’ve done it well – and other times not quite so well. The potential harms and benefits are significant...” “...Other government uses of AI are being questioned, too – such as attempts at 'predictive policing,' setting bail amounts and criminal sentences and hiring government workers. All of these have been shown to be susceptible to technical issues and data limitations that can bias their decisions based on race, gender or cultural background. Other AI technologies such as facial recognition, automated surveillance and mass data collection are raising real concerns about security, privacy, fairness and accuracy in a democratic society....” “...As the use of AI technologies grows, whether originally well-meant or deliberately authoritarian, the potential for abuse increases as well. With no currently existing government-wide oversight in place in the U.S., the best way to avoid these abuses is teaching the public about the appropriate uses of AI by way of conversation between scientists, concerned citizens and public administrators to help determine when and where it is inappropriate to deploy these powerful new tools.” Are you a reporter covering AI?

Can Understanding the History of Drug Addiction Help Address the Opioid Epidemic?
According to the National Institute on Drug Abuse, more than 130 people die every day after overdosing on opioids. Lives have been lost, families shattered, and billions spent as experts, elected leaders, health care professionals, and law enforcement officials try to address the country's opioid epidemic. A professor at Rensselaer Polytechnic Institute can help shed light on the forces at work in this crisis and its history. Professor Nancy Campbell is an expert is in the history of science, technology, and medicine as it relates to drug policy and the social significance of drugs. She is a professor and head of the Department of Science and Technology Studies (STS) in the School of Humanities, Arts and Social Sciences at Rensselaer Polytechnic Institute. "We found her to be one of the most knowledgeable people on the history of opioids and how that history fits into the context of today’s problem," reporters for CBS 6 News in Albany wrote of Campbell. In a recent interview with the station, Campbell discussed her extensive research on the history of drug addiction, as well as her approach to educating students about it. “I actually want my students to go out of the class, knowing more about where our current opioid epidemic came from, the endemic that it built upon and also knowing more about drug markets and the social aspects,” Campbell said.

Preacher Archives Add New Element to Baylor University’s Black Gospel Music Restoration Project
The Black Gospel Music Restoration Project at Baylor University is preserving more than just gospel music. In the past few years, Baylor journalism professor and former Billboard gospel music editor Robert Dardenand a team from the Baylor Libraries have undertaken the project of restoring and preserving recorded sermons from black preachers in addition to the gospel music. While both are equally important to preserve, finding sermons to preserve comes with a unique set of challenges. Darden said the idea for preserving sermons started about four years ago, when the BGMRP team was in contact with the daughter of the Rev. Dr. Marvin Griffin, former pastor of New Hope Baptist Church in Waco. Griffin was a renowned Civil Rights leader in Central Texas and boasts a list of significant firsts, including first black man to earn a degree from Southwestern Baptist Theological Seminary and first African-American president of the Austin Independent School District board of directors. Darden said somebody mentioned in passing that they kept Griffin’s sermons and said he ought to hear them because they are full of music. “All black preachers sing, and all black singers preach,” Darden said. “That got me thinking – nobody has been collecting the black preaching from the Civil Rights movement, other than Dr. King. All these incredible heroes who were preaching around the rest of the country, there’s not a collection of their work. So, I met with the other folks in the Black Gospel project, and we agreed that in addition to the music, we ought to be trying to collect preaching.” Many of these sermons had been recorded on vinyl, and Darden said some have even speculated that it was black preaching that started black gospel music in the 1930s. He said some records that were just a black preacher preaching for two and a half minutes on each side sold half a million copies – even during the Great Depression. Digitizing sermons from different formats When the BGMRP was founded in the Baylor Libraries in 2005, the bulk of incoming materials focused on recorded gospel music. Over the ensuing decade, the BGMRP team realized they already had hundreds of vinyl LPs from famous preachers in their collection. Shortly after, they started receiving sermons in many different formats. Darryl Stuhr, associate director of the Libraries’ digital preservation services, consulted with Darden and together they decided they needed a collection to show to preachers and their families who were not familiar with the projects, in hopes of convincing them to trust the project with their sermons long enough to digitize them. Darden worked with two in particular – the Rev. E.E. Jones in Shreveport, Louisiana, and the Rev. Clay Evans in Chicago, who is still preaching at 93-years-old. “Evans) was one of only two preachers who helped Dr. King in Chicago during those really rough times, and they had collected video cassettes of him back into the ‘70s,” Darden said. “That’s the good news. The bad news is they kept them in unairconditioned or unheated warehouses.” Darden said the BGMRP spent lots of money getting these cassettes stabilized enough to play them even just one time so they could be digitized. Using technology at the Libraries’ Riley Digitization Center, audiovisual digitization staffers Stephen Bolech, Travis Taylor and Hannah Engstrom are able to rescue the recorded sermons from other formats as well, including videocassette, film and digital audio tape. The wide range of formats the BGMRP team can work with means a greater number of sermons can be saved, Stuhr said. “They’re not all in the best condition, but they’re just thrilling because (Evans’ church) is one of the largest historic African-American churches in just full 1970s regalia. We got (Jones and Evans) and we’ve been using those to approach other preachers and their families now. This is already the largest collection in the country, and we just started,” Darden said. Recently, Darden got a call from PBS. Dr. Henry Louis Gates of the TV series “Finding Your Roots,” whom Darden quotes in his books, will have a new six-part series on the history of African-American churches in America debuting in 2020. Darden said they contacted him about providing materials for the show and contacts of people. The BGMRP already has made hundreds of copies for PBS and is communicating about how they can help. “I’m hoping they’re going to come down and do some filming here as well, because a lot of the stuff we have is old bulletins and the sheet music – we just have everything. Sure, we can digitize it, but if they came down, they could array it in such a way from an artistic standpoint,” Darden said. Search continues Darden got together with some of the “preaching folks” at Baylor and put together a top 10 wish list of influential black preachers of the past 50 years whose sermons they would like to digitize. “I just think God put me in a place where I could facilitate, rather than me initiate, and it was God’s idea apparently, because it wouldn’t have worked this well otherwise,” Darden said. Darden said new vinyls continue to come in every few days, and it is like Christmas for him to go see what is new. “I don’t mind not knowing every artist or every preacher – there’s hundreds and thousands of them,” he said. “But what scares me is when I pull a piece of vinyl out and it’s a label that I don’t know, which means there’s another whole line of that label that we’ve never heard of. So here we’re sitting 15 or so years into this project, and I don’t know if we have 1 percent of what’s out there – 10 percent? There’s no database. Nobody knows.” “It’s unlike every other kind of music. Nobody ever made a discography of gospel music,” Darden said. “So, whether we mean to or not, we’re actually putting that together as well. Trying to figure out how many Andraé Crouch albums, how many James Cleveland, how many Rosetta Tharpe, and now with preaching, it could go on forever. It’ll be going, hopefully, long after I’m gone.” For more information or to learn how to donate materials, visit the Black Gospel Music Restoration Project at www.baylor.edu/library/gospel or email digitalcollectionsinfo@baylor.edu.
Whether making the transition to college, starting a new job, ending a relationship or retiring, change can cause psychological stress, which in turn can make for wear and tear on the body. The good news is, we can develop coping mechanisms to reduce stress and live happier, healthier lives, say Baylor University psychologist Annie Ginty, Ph.D., and her University of California-Irvine collaborator, Sarah Pressman, Ph.D. Using a grant from AXA Research Fund — which supports projects in health, environment, new technology and socioeconomics — Ginty and Pressman produced three short videos to help students and the general public understand what stress is, what it does to our bodies and how to handle it. The videos stem from a two-year AXA postdoctoral research fellowship by Ginty, assistant professor of psychology and neuroscience in Baylor’s College of Arts & Sciences. She investigated the relationship between biological responses to stress and adaptation during a stressful transition, particularly students’ adjustment to college. The videos, 1 to 3 minutes each, are housed on AXA’s YouTube channel and bear Baylor's new logo. “Psychological stress is bad for health; exercise stress is good,” said Ginty, who works with nonprofits to serve at-risk adolescents by providing high-intensity interval training workouts to reduce stress and improve health. “When we think about exercise, your heart rate and metabolic system increase, meaning you’re breathing harder. The rest of your muscle physiology is changing. Your body is working together to maintain homeostasis for balance. This is good stress,” she said. “But with psychological stress, the heart works much harder than the rest of the body. That metabolic imbalance can be hard on the heart and make the body more vulnerable to disease.” In the videos, Baylor students discuss the causes of psychological stress in their lives, how their bodies react and ways they handle stress. For them, a college education poses looming deadlines, fear of living up to expectations, anxiety about tests and adjusting to a new atmosphere. In the first video — "Stress and Your Health" — they describe such reactions as higher heart rate, restlessness, loss of sleep, skin breakouts, headaches and tense muscles. “If I fail at a test, I then in my mind see myself not getting into medical school, which is a pretty big domino effect,” said Devin Mangold of Wolfforth, Texas, a senior neuroscience major in the Honors College at Baylor. Such stressors can take a toll on moods and emotions, putting the physiological stress system into overdrive and possibly becoming a threat to long-term physical health — which in turn creates more stress. The second video — "Effects of Stress on Your Body" — explores how stress can affect emotions and the body. Stressed people may become anxious, sad, worried and angry. The stressors can interfere with sleep and can leave less time to exercise. People also tend to eat foods with higher fat and higher carbohydrates, said Pressman, associate professor of psychological science at UC-Irvine. That can lead to muscle tension, which can translate into injury. The third video — "Coping with Stress" — is about the importance of coping mechanisms so that minor stressors don’t turn into serious health issues. Social networking has been shown by research to reduce the effects of stress in such ways as lowering blood pressure. The best ways to cope are physical activity, a healthy diet and cognitive reappraisal. “Cognitive reappraisal” is “a fancy way of saying we’re changing how we interpret our situation,” said Danielle Young, Psy.D., clinical research coordinator of the Baylor Behavioral Medicine Laboratory in the department of psychology and neuroscience department. “It’s the difference between saying, ‘This is going to be the hardest test ever, and I’m going to fail’ and ‘This is going to be a hard test, but I’m going to do the best I can.’ Even that slight shift in thought can make you less stressed.” A recent study by Ginty of 230-plus Baylor students examined the effect of reappraising stress. “We found that if we gave brief instructions about how increases in heart rate during stress mean they were ‘ready’ and were not a ‘bad thing,’ people rated their levels of anxiety as more helpful to their performance,” Ginty said. The video encourages individuals to experiment with coping techniques that work for them. Students who appear in the video suggest methods from working out to cooking to reading to walking their dogs. “My natural demeanor is laid back, but internally, I stress myself,” said senior neuroscience major Simba Masando of Harare, Zimbabwe. Early in college, he “just went headfirst into the material” of a capstone course. “Now as a senior, I’m doing some preliminary courses I’m not necessarily interested in, but they’re required. I’ve alleviated some pressure in the major, but some of the requirements are a little more worrisome.” As a member of Baylor Behavioral Medicine Lab, what he’s learned about stress oping has been “greatly helpful” as he looks ahead to post-graduate school and his eventual goal of opening a school in Zimbabwe. “I’m an avid learner,” he said. “School is my job, as I see it, but my hobbies are learning, too. In basketball, there’s always a new move I want to learn; in piano, there’s a new technique. If you take the piano away from me, I’ll try guitar. And if you take basketball away from me, I’ll try tennis.” ABOUT ANNIE GINTY Research articles by Annie Ginty, Ph.D., include: “The behavioural, cognitive, and neural corollaries of blunted cardiovascular and cortisol reactions to acute psychological stress,” published in ; “Challenge and threat imagery manipulates heart rate and anxiety responses to stress,” published in ; and “Depression and anxiety are associated with a diagnosis of hypertension 5 years later in a cohort of late middle-aged men and women” published in ABOUT BAYLOR UNIVERSITY Baylor University is a private Christian University and a nationally ranked research institution.

The Gun Control Debate is at a Stalemate. Can Smarter Weapons Help to Solve it?
The gun control debate is at a stalemate. America seems incapable of finding common ground on background checks, waiting periods, weapons registries and restrictions or bans on select weapons. Shooting after shooting has resulted in decades of debate but little substantive change. But Professor Selmer Bringsjord from Rensselaer Polytechnic Institute, who recently weighed in on the issue, presented a concept that could turn the entire topic on its head by using artificial intelligence. Bringsjord accepts that America won’t get rid of its guns – so why not just make our guns smarter? Ethically AI-enabled weapons can put American politicians back to work by shifting the debate from the weapons we should ban, to the targets we will accept. Do we allow guns to kill school children, shoppers, concert-goers? The technology of ethical AI changes the conversation. His idea was just recently published in the Times Union: “Yet there is a solution, a technological alternative to the fruitless shouting match between politicians: namely, AI — of an ethical sort. Guns that are at once intelligent and ethically correct can put an end to the mass-shooting carnage. Consider the rifle apparently used by the human killer in the El Paso Walmart shooting. But now suppose that time is turned back to before his shots were fired on Aug. 3, and that his rifle, radically unlike the stupid one that killed, is both intelligent and ethical. This alternate-future rifle would know that it's approaching the Walmart by car and would accordingly know that it has no business being used anytime soon. Move forward in time a bit; the rifle is now in the hands of the aspiring, ear-muffed killer outside his car; but his weapon has fully disengaged itself and is locked into a mode of utter uselessness with the finality of a sealed bank vault. On the other hand, the guns in the hands of law enforcement officers who have dashed on scene know in whose hands they rest, and accordingly know that if they are trained on the would-be killer, they have every right to work well, if this criminal reveals some new threat. Notice: If people who don't actually pose a threat sufficient to warrant being shot by police can't be shot by smart, ethical guns, a fact that could lead to the welcome evaporation of a different but also vitriolic political shouting match.” -Times Union, August 16, 2019 Could AI be the answer to America’s gun problem? It’s truly a new perspective on an old issue. If you are a reporter covering this topic, let our experts help with your story.
