West Sanctions Russian Aviation, But Moscow Decides to Keep Planes Flying Despite Risks When the U.S. and its allies slapped sanctions on Russia for its full-scale invasion of Ukraine, severing aviation links was at the top of the list. Direct flights vanished and Russian airlines lost access to spare parts for their foreign airplanes. In retaliation, Vladimir Putin’s regime impounded foreign aircraft and shut off the world’s largest air space to countries imposing sanctions. Not since the early 1980s—when the U.S. suspended routes to the USSR over the Soviet invasion of Afghanistan, repression in Poland and downing of a Korean Air Lines plane—have aviation ties between the two countries dipped so low. Aviation sanctions today are having an impact but come with a major risk. If the fatal crash of a jetliner killing hundreds is linked to the lack of spare parts, Putin will blame sanctions and the West. The stakes are high as Russia seeks to use any issue from cluster bombs to soccer to widen cracks in Western unity over Ukraine. To get ahead of this, U.S. policymakers and their allies need to better explain the effects of sanctions, why they’re worth the risk and why the Russian state, not the West, is ultimately responsible for any fatal crash. U.S. government assessments place Russian aviation among sectors negatively impacted by sanctions. A closer look shows widening success in degrading this increasingly weak link in Russia’s political economy. By late 2021, foreign aircraft comprised 70% of Russia’s fleet of 801 passenger airplanes, which included 298 Airbuses, 236 Boeings, and 23 other foreign aircraft such as Embraers. In addition, 95% of Russian airline flights were on foreign-made aircraft. Consequently, sanctions aimed at depriving spare parts for foreign airplanes have caused many disruptions such as fare increases to cover higher costs of repairs. Some of Russia’s 53 airlines have periodically suspended or stopped flying some of their foreign planes. Reports of Russian airlines’ cannibalization of foreign aircraft similarly underscore a dire situation. Less well known is how sanctions hurt Russian manufacturing since Western technology is critical to aircraft such as the Sukhoi Superjet 100, which uses a French-Russian engine (though Russians are working on a substitution). Production of the Yakovlev design bureau’s MC-21 passenger airplane faces significant delays due to sanctions that force substitution of its Western-made parts. Sanctions even helped push Russia out of a joint venture with China to produce the CR929 widebody aircraft. While China is happy to help Russia thwart sanctions, this plane needs Western systems that sanctions complicate. In response, Russia has adapted to and thwarted some aviation sanctions, which I predicted would happen because Putin’s regime is reproducing a state-centered aviation sector rooted in the Soviet past. The war has accelerated the state’s growing control over this vital economic sector, which began before Russia’s 2014 invasion of Ukraine. Examples include the state’s 51% ownership of Aeroflot since 1994, the merger of two smaller, state-run airlines in 2003 and the consolidation of aircraft manufacturing in the state-owned United Aircraft Corporation (UAC), which was created in 2006. More recently, the Russian state has helped the country’s airlines weather sanctions by facilitating the illegal confiscation of foreign aircraft. Russian airlines have also proven resourceful by purchasing spare parts through brokers in the United Arab Emirates and Turkey. Better known for supplying Russia with drones, Iran also agreed to provide Russian airlines with spare parts and has been fixing an Aeroflot Airbus for months. Many foreign airlines continue to fly to Russia, and Putin’s regime rewards friendly countries with overflight rights. But the longer sanctions remain, the harder it’s getting for Russia. To regain profitable foreign routes, its airlines are receiving government assistance to legitimately purchase the Western aircraft they illegally seized, although recent holdups in allocating such funds are causing doubts. In a throwback to the Soviet era, Putin’s regime boasts that Russia doesn’t need the West’s airplanes anyway since its one manufacturer, the UAC, will pick up the slack. Such import substitution is unlikely to succeed, as multiple delays suggest. More likely, Russia’s aviation sector will grow more reliant on the state, if not actually part of it like the UAC. This will make Russian aviation less efficient, less innovative and more expensive. Iranian airlines, which have long suffered under foreign sanctions despite some success circumventing them, present their Russian counterparts with a grim vision of the future such as being shut out of lucrative air travel markets and falling behind in emerging aviation technology. How does this shape safety in Russia’s skies? The short answer is that it’s not as bad as headlines suggest and the impact of sanctions is ambiguous at best. Click bait stories paint a dire picture but often conflate commercial, military and general aviation into alarming numbers that do not accurately capture what ordinary passengers face. Some accounts, such as one claiming 120 accidents occurred in 2023, provide few details or sources. Annual safety reports from Russia’s Interstate Aviation Committee (IAC) allow for comparison over time but often obscure Russia’s situation by combining data from each post-Soviet state it monitors. Its 2019 report is mysteriously missing and its decision not to investigate the fatal crash of Yevgeny Prigozhin’s Embraer Legacy 600 plane suggests meddling from above. That said, the IAC source base is the most systematic we have. Keeping in mind the potential for the politicization of its conclusions, what does a critical reading of its data alongside other sources suggest? First, fatal crashes in commercial and general aviation actually decreased in Russia from 18 in 2021 to 13 in 2022, and related deaths decreased from 70 to 24. Data for the first half of 2023 points in the same direction, with six fatal crashes and nine deaths. This trend was likely helped by the 14% decline in traffic after February 2022. While so many fatal crashes sound substantial, all but three in 2021 and all but one in 2022 involved small aircraft under 5,700 kilograms, not the jetliners we associate with most commercial flying. Absolute figures on crashes and deaths capture headlines but they don’t say much about safety without considering their relation to passengers flown or departures. According to the IAC, the rate of aviation accidents and the rate of fatal crashes per one million departures both increased from 2020 to 2021 but then decreased in 2022. The IAC does not single out Russia from other post-Soviet states for this metric. But since Russia has the largest aviation sector among those countries, these data suggest that its aviation safety has not dramatically worsened since early 2022. Indeed, even critics who argue that Russian airlines are less safe partly because of sanctions conclude that “2022 and 2023 were also good years for airline safety [in Russia] compared to 2021.” Comparisons with the U.S. similarly suggest that passenger aviation is not as disastrous as some headlines suggest. The IAC data indicates that Russia and other post-Soviet states are usually but not always behind the U.S. in passenger aviation safety. In 2018, for example, IAC countries reported a 0.8 rate of fatal crashes per 1 million departures of passenger aircraft above 5,700 kilograms. Comparable statistics from the National Transportation Safety Board showed a 0.11 rate for that year for scheduled U.S. carrier flights. In 2019, the rates were 2.3 (IAC) and 0.10 (U.S.), but in 2020, both IAC countries and the U.S. enjoyed a 0.0 rate of fatal crashes. The following year, however, IAC countries reported a 1.9 rate of fatal crashes, whereas the NTSB reported a 0.0 rate.1 Against this background of Russian airline safety, let’s now turn to the impact of sanctions. While some commentators emphasize that no fatal crashes have been tied to sanctions, others claim they make Russian airlines unsafe and that it’s only a matter of time before such a fatal crash happens. Some even argue that life-threatening dangers prove aviation sanctions are effective and could help turn Russians against Putin. To reassure the public, Russian aviation officials insist the country’s airlines are safe despite sanctions, as do Russian business media and aviation journalists. This plays to Putin’s claims to legitimacy based in part on withstanding anything the West throws at him. In sharp contrast, Ukrainian media tells Russians their airlines are a disaster waiting to happen precisely because of sanctions. Independent Russian journalists banished by Putin concur, raising alarms about efforts to cover up the impact of sanctions and about the many ways Russian airlines cut corners on safety. In short, an information war exists around the morbid question of whether a Russian jetliner will crash and the role sanctions could play. Fears of a fatal crash were validated by the emergency landing of a Ural Airlines A320 in September, apparently caused by malfunctioning hydraulics tied to sanctions. But a closer examination by a Russian aviation journalist suggests the pilots played a more important role by pressing on to an airport for which there wasn’t enough fuel. Recent Russian state assessments of aviation safety similarly point to pilot error and poor training as the chief causes of aviation incidents. More generally, airplane disasters are usually caused by a convergence of factors—bad weather, a manageable mechanical failure and pilot error—not just one problem. In public discussions, however, pinpointing sanctions’ role tracks more with the politics of the war than technical expertise. At the end of the day, Russian airlines and aviation authorities are solely responsible for putting planes in the sky and Russians’ lives at risk. They continue to claim that everything is fine. But if a fatal crash of a Boeing or Airbus flown by a Russian airline kills hundreds, I predict this narrative will quickly change. Putin will blame the West as he does for everything else affecting his legitimacy, from Russia’s economic problems and his diplomatic failures to protests against his regime and even the war he started in Ukraine. Such a scenario will be a serious test for policymakers who argue that punishing Russia with sanctions is still worth it. To prepare for this, they need to take a page from the Biden administration’s release of intelligence on Russia’s military buildup before the full-scale invasion: publicize as much intelligence as possible on sanctions and their impact, as well as Russia’s aviation sector and what it does or doesn’t do to ensure safety. As Putin’s regime falls back on Soviet-era secrecy about airline safety, sharing such intelligence will be a powerful tool. This will also contribute to broader Western efforts at combatting Russia’s better known disinformation campaigns such as those denying its human rights abuses in Ukraine.
Sport and Study: Villanova University Faculty Offer Academic Lens to Paris Olympics Storylines
All eyes are on Paris: more than 10,000 athletes from 206 nations are set to compete in the Games of the XXXIII Olympiad, the third Olympics in the City of Love and the first since 1924. Below, Villanova University faculty members provide their academic expertise on the unique storylines and narratives already taking place as Paris 2024 gets underway. Portraying a National Image in the Opening Ceremony Étienne Achille, PhD Director of French and Francophone Studies After months of speculation, the daily Le Parisien has officially confirmed that renowned French-Malian singer Aya Nakamura will lend her vocals to an opening ceremony featuring an iconic backdrop steeped in history. “Nakamura is the most-streamed Francophone singer in the world, embodying France’s culture on a global stage, and she’ll be paying homage to one of the most cherished representatives of the chanson française,” said Dr. Achille, referring to reports she will sing one of beloved French crooner Charles Aznavour’s greatest hits. According to Dr. Achille, the pop star’s presence is significant and symbolic. “A performer, or even a flagbearer, can easily become the face of a global event like the Olympics,” he said. The details of the setting for the ceremony – in the heart of Paris, along the Seine – are just as intentionally symbolic. “Not only will this be the first opening ceremony to take place entirely outside of a stadium; its location along the river and the fact the delegations will be on boats are key. “It represents movement and connection to the world,” Dr. Achille said. “And Nakamura’s performance projects the image of a modern, multi-ethnic nation building on tradition while proudly marching into the future.” Swimming in the Seine: Safe or Not? Metin Duran, PhD Professor of Civil and Environmental Engineering It is, perhaps, the most-asked question of the last few weeks. Is the Seine River, set to host multiple swimming events, safe? The river has been illegal to swim in for a century due to the presence of harmful bacteria such as E. Coli, and recent testing has reaffirmed this concern. The Seine, which had undergone an expensive cleaning to mitigate this issue, received the endorsement of Paris Mayor Ann Hidalgo, who personally took a dip in the water herself to attest to its safety. The stunt did little to convince experts such as Dr. Duran, who studies wastewater, to abandon concern about the potential health risks of athletes being exposed to pathogens in the water. “When we have fecal pollution, there is a high likelihood of pathogens being present,” Dr. Duran said. “Those could be viral, like a norovirus, or protozoan. “If you’re swimming in that water, you run the risk of ingesting it. Once you ingest that polluted water, you’re likely to contract some of those disease-causing pathogens. Ingesting this water doesn’t mean you’re necessarily going to get sick, but based on the number of people in a big city like Paris, there is a very high likelihood of some of these pathogens existing now in the river.” Accommodations for Breastfeeding Athletes Sunny Hallowell, PhD, APRN, PPCNP-BC Associate Professor of Nursing The IOC and Paris 2024 Organizing Committee is providing support to all breastfeeding athletes competing in the Games. A few national governing bodies, like the French Olympic Committee, are going a step further and offering hotel rooms near the Village for their country’s breastfeeding athletes to share with their children and spouses. “A few decades ago, the idea of a female athlete who also wanted to breastfeed their child was so taboo it may have prevented an athlete from competing,” said Dr. Hallowell. “Now, many female athletes who choose to breastfeed their newborns or toddlers conceptualize breastfeeding as another normal function of their remarkably athletic bodies.” Accommodation for breastfeeding athletes and increased awareness are needed more than ever. Dr. Hallowell notes that in addition to changing views on breastfeeding, the needs for such accommodations are increasing as the age of peak athletic performance also increases. “Advances in sports nutrition, wellness and lifestyle have extended the longevity and performance of many athletes into adulthood,” she said. And while some athletes with rigorous training regimens might feel “frustrated incorporating breastfeeding into the routine,” Dr. Hallowell says that for others, “breastfeeding provides both physical and socio-emotional benefits for the mother and the infant that allow the athlete to focus on the job of competition.” Protecting Against the Parisian Heat Ruth McDermott-Levy, PhD, MPH, RN, FAAN Professor of Nursing The potential for extreme heat in Paris has been a topic of concern for athletes and organizers, prompting certain outdoor events to be proactively scheduled at times to avoid the day’s worst heat. Current forecasts predict temperatures in the 90s for several days early on in the Games, which could be exacerbated by Paris’ reputation as an urban heat island, unable to cool due to lack of green space and building density. Dr. McDermott-Levy says the athletes are inherently vulnerable, because “the added stress of physical exertion during their events puts them at greater risk of heat-related illness.” But she also notes that many of the athletes have likely undergone pre-competition training in extreme heat conditions to acclimate and will have trainers and health professionals monitoring them frequently. “The group of concern are the workers at the stadiums, outdoor workers and spectators who are there to enjoy or work at the events and may have had little to no acclimation,” Dr. McDermott-Levy said. “They need to follow local instructions and take frequent breaks from the heat, seek shade and maintain hydration by avoiding alcohol and sugary drinks and drinking water.” How Nature Can Inspire Future Use of Olympic Infrastructure Alyssa Stark, PhD Assistant Professor of Biology Gone, hopefully, are the days of abandoned Olympic Villages and venues, overrun with weeds and rendered useless soon after the Games conclude. The IOC’s commitment to sustainability has been transparently relayed ahead of the 2024 Games, featuring a robust range of initiatives and programs. Dr. Stark is particularly interested in one aspect of ensuring a sustainable Olympics. “How will the structures, materials and systems they developed for the Olympics be re-used, re-shaped or re-worked afterward?” she posed. “This could include re-using buildings to larger scale or re-working transportation systems set in place for the Games that could then integrate into day-to-day life post Olympics.” At the root of her interest is the concept of biomimicry. “A lot of the way we think about designing, if we’re using this biomimicry lens, is how do we learn from nature to solve problems that we have in a sustainable way, keeping in mind the environment we are in?” Dr. Stark said. In this case, consider how something like a dwelling of a living creature might be repurposed to fit the needs of another creature, or serve another natural purpose, without harming the ecosystem. Could that inspire a way to re-use the Olympic infrastructure? “There are a ton of examples of [biomimicry] being used and working in products,” Dr. Stark said. “But I would say the next step is looking at the social levels of these big ecosystems – building architecture, city planning, flow of information and, in this instance, repurposing what was created for the Olympics.” Paris Could Be a Transportation Model for Major City Events in the United States Arash Tavakoli, PhD Professor of Civil and Environmental Engineering Paris has invested 250 million Euro the last several years to transform the city to a 100% cycling city, making it one of the most bike-friendly municipalities in the world. Currently, more trips are being made by bicycles in Paris than by cars (11% vs. 4%), a trend that has permeated to the surrounding suburbs as well. With an influx of travelers in Paris for the Games, Dr. Tavakoli, an expert in human transportation, said, “The Olympics will be a test for how well these kinds of systems respond to high fluctuations in the population as compared to vehicle-centric systems.” While Paris is thousands of miles away from the United States, how bicycle, pedestrian and vehicle systems work during the Games could provide helpful insight ahead of major events in American cities. “With the World Cup coming to the U.S. in a few years, it will be interesting to compare [Paris] with how our own system responds to people’s needs,” Dr. Tavakoli said. “Not just based on traffic data and congestion, but also considering factors like how comfortable the transportation system is, how much it affects our well-being and how much it attracts a nonresident to enjoy the U.S. when their only option, for the most part, is a vehicle.”
Aston Institute of Membrane Excellence’s Dr Matt Derry was joined by Dr Alan Goddard and France-based research partner Dr Mona Semsarilar They discussed the BIOMEM project, which received £3m from the European Innovation Council (EIC) Pathfinder programme BIOMEM will develop a bioinspired membrane to selectively extract compounds from water (like finding a favourite chocolate in a box) In the latest Aston Institute for Membrane Excellence (AIME) podcast, three researchers discuss the international BIOmimetic selective extraction MEMbranes (BIOMEM) project and how it will feed into AIME’s work. BIOMEM will develop a bioinspired membrane technology to selectively extract compounds from water, using 50-75% less energy than current state-of-the-art nanofiltration technologies. The membranes will work at low pressures and at low concentration of the target molecule. Podcast host Dr Matt Derry was joined by fellow AIME researcher Dr Alan Goddard and Dr Mona Semsarilar from the French National Centre for Scientific Research (Centre national de la recherche scientifique (CNRS)). The BIOMEM project, which involves collaborators from across Europe, is being led by Dr Torsten Bak from Danish company Aquaporin, with Dr Goddard the research lead at Aston University. Dr Goddard explained: “You might want to work on a biotechnology process where you've made a high value chemical that you want to extract from a complex mix, and at the moment you might have to concentrate your solution up, and you might have to do six or seven filtration steps. We want a filter that does it in a single step using a biological transporter. “And if you can do that in a single step in a platform technology, you'll make all these brilliant biotech processes more commercialisable, reduce your reliance on petrochemicals, and to maybe oversell what we can do, save the planet.” Dr Derry likened it to a quick way to find your favourite chocolate in a box at Christmas. Rather than scrabbling through, taking out one type at a time until you find your favourite, the process can immediately separate it out with minimal effort. Aquaporin has developed a membrane that can selectively transport only water molecules to quickly purify water, which is already in use across the world, and even out of this world, for space missions. Dr Bak and the team will bring their membrane expertise to the project. The team at CNRS, led by polymer scientist Dr Semsarilar, is working on a number of projects for BIOMEM, including developing a type of crystalline material called trianglamine, which they can modify through chemical processes to be hydrophobic or hydrophilic to make things like water channels or adsorption sites, which can be embedded in polymer network for purification processes. Other researchers at AIME, including Dr Derry and Professor Paul Topham, will work on the ‘glue’ to stick the biological elements of the membranes to the non-biological polymer matrix. BIOMEM will also benefit from the input of partners across Europe including dsm-firmenich, University of Copenhagen and Tampere University. The podcast was recorded just after the project kick-off meeting with all the project partners, which was held at Aston University in May 2024.

Frequent tanning can signal excessive concern over image and vulnerability to taking health risks, researcher says Getty Images People who often sunbathe or use tanning beds are more likely to try risky weight-loss methods and have cosmetic surgery, as well as get tattoos and piercings. But while people who seldom tan also may try unsafe diets and cosmetic surgery, they rarely opt for tattoos or piercings, according to a Baylor University study. "When compared to infrequent tanners, frequent body-tanners — regardless of whether they are tanned by ultraviolet light from the sun, ultraviolet light from a tanning bed or methods such as tanning sprays that do not involve UV light — showed significantly higher behavioral intentions to engage in risky appearance-related behaviors overall," said Jay Yoo, Ph.D., associate professor of family and consumer sciences in Baylor's Robbins College of Health and Human Sciences. "Safer tanners, on the other hand, are more concerned about modifying their bodies in ways such as tattoos and piercing that may carry a stigma," Yoo said. Most skin cancer prevention campaigns have emphasized avoidance of getting sunburned, reducing UV exposure and applying sunscreen, but they have neglected the individual's experience with social and appearance concerns, he said. But "Excessive tanning can serve as a possible sign of overt concern over body image, with vulnerability to greater health risks," Yoo said. His research article — "A Study of the Relationships between Tanning Methods and the Intention to Engage in Risky Appearance-Related Behaviors" — is published in Family and Consumer Sciences Research Journal. Data for the study was collected from an online survey of 395 female college students in the southern United States. The major contributor to skin cancer is frequent exposure to ultraviolet rays, with skin cancer the most common — and one of the most preventable — types of cancer, according to the American Cancer Society. Ironically, previous research has found that many people choose to tan because they believe a tan makes them look thinner and more fit, Yoo said. Tanning has gone in and out of fashion, Yoo noted. Tans at one time were associated with lower classes who worked outdoors — in contrast with the Southern belles of more than a century ago, who used parasols to protect their skin and to look pale and refined. In the 1920s, fashion designer Coco Chanel started a fad after accidentally getting sunburned while visiting the French Riviera, Yoo said. Tanning remained popular, with high-fashion models often sporting tans, whether from UV exposure or sprays and bronzers. And these days, some people sport tattoos along with their tans, he said. The study found that: Frequent tanners who expose themselves to UV rays through sunbathing or tanning beds have the strongest intentions to engage in a wider range of risky appearance-related behaviors when compared to infrequent tanners or spray tanners. Such behaviors include extreme weight control methods, such as diet pills, self-induced vomiting, laxatives and diuretics; cosmetic surgery and Botox injections; spa treatments, such as hair removal by waxing (which has been associated with rashes and infections) and gel nail polish (done with UV curing and associated with DNA damage to the skin that can result in premature aging and possibly cancer; and tattoos or piercings. Infrequent tanners, as well as "safe" tanners who seek to achieve an ideal tan without ultraviolet methods (sprays, lotions or bronzers) are much less likely to engage in behaviors that may convey certain stereotypes, such as tattoos or piercings with visual symbols or messages. But they are willing to try other risky appearance-related behaviors. Yoo suggested that intervention strategies adapted for healthcare providers to reduce UV exposure and skin cancer could use stigmatization — perhaps through images of tattooed or pierced individuals who also are tanned. "A negative stigma attached to UV exposure can create ambivalence in our society about achieving a tanned appearance," Yoo said. "This could decrease the popularity of tanning in much the same way the negative stereotyping of smoking and education about its health risks have reduced the number of people who smoke." He noted that in the 1940s and 1950s, smoking was idealized, especially in Hollywood movies, but "there has been a cultural shift," he said. "One way to change the appeal of tanning would be to make it un-cool," Yoo said. "If I tan and people look at me funny, I'm not going to tan anymore." While another way to stigmatize tanning would be to stress the health consequences, "for young people it may be more effective to emphasize the appearance," Yoo said. "The tanning that makes me attractive now may be counteracted for the long haul because at 50 or 60, I may have leathery skin. "Given that tanning emerged as a fashion trend, gradual attitudes toward dangerous tanning can be made possible in a similar fashion," he said.
Expert Insight: The Voice of Alexa: How Speech Characteristics Impact Consumer Decisions
In the 2020 film “Superintelligence,” an all-powerful artificial intelligence attempts to take over the world, and it studies an average person, played by Melissa McCarthy, to decide if humanity is worth saving. The AI is voiced by James Corden—a voice it chooses because it knows it’s one McCarthy’s character will engage with. Rajiv Garg, associate professor of Information Systems & Operations Management at Emory’s Goizueta Business School, shows the “Superintelligence” trailer before his research presentations to set the tone. Garg conducts research that explores the impact of artificial intelligence voices on consumer behavior and purchase intent, along with Haris Krijestorac, a professor at HEC Paris, and Vijay Mahajan, a professor from The University of Texas at Austin. Garg’s research began when Amazon launched celebrity voices for its Alexa device in 2019. From Samuel L. Jackson to Shaquille O’Neal, users can now get their news and entertainment, while interacting with their favorite superstars. “I questioned if certain voices could get more engagement or more purchases from consumers,” Garg says. If Alexa starts talking to you in Samuel L. Jackson’s voice, will you continue the conversation? What could Samuel L. Jackson’s voice sell you that you would buy? Garg and his team began their research by collecting more than 300 celebrity voice samples, which they analyzed based on their sound characteristics, such as amplitude, frequency, and entropy. They looked at 20 sound characteristics and identified that all the voices could be segmented into six clusters: ostentatious, colloquial, friendly, authoritative, seductive, and suave. The team then created advertisements for select products using computer generated voices for each of the six clusters, opting for artificial intelligence-created speech instead of celebrity deep fakes due to permission legalities. They chose a shoe and an office chair as their products, and created two different advertisements for each product. One ad was simple, denoting the shoe as comfortable for all-day wear and the office chair as comfortable for sitting in for extended time periods. The other ad was hedonic, denoting the shoe as crafted with Italian leather and the office chair equipped with several massage features. They recorded the four advertisements using both a female and male voice for all six voice clusters. Study participants listened to each of the four advertisements in one of the 12 voices, which was randomly selected. After the advertisement was played, participants were asked if they wanted more information, and later, if they wanted to buy the product (omitting the price as to not add another factor to their decision making). Influencing Consumer Behavior For simple, utilitarian products, they found no significant effect of voice on information seeking behavior. Garg says once participants hear this type of advertisement, they simply decide to purchase or move on. Participants do, however, engage more in information seeking behavior for hedonic products when the voice is ostentatious, seductive, or authoritative. The team also found men were more likely than women to engage with ostentatious or seductive voices, and women were more likely to engage with friendly or colloquial voices. Overall, they found participants did not seek information with male voices. For information seeking, men and women only engage if the voices are female, which is somewhat intuitive. The industry is doing this—Alexa, Google, and Siri all have a female voice. In terms of purchase intention, they found ostentatious voices have higher yields for utilitarian products. Men, especially, were more likely than women to purchase a utilitarian product advertised in an ostentatious voice. Think about advertising a stapler. It’s a stapler—it staples paper—but you advertise it in a French accent to make it sound interesting. Conversely, for hedonic products, an ostentatious voice has a negative effect on purchase intent because Garg says it can make the product sound gimmicky. Their research shows colloquial voices do the best here because people focus more on the advertisement’s content. Across the board, they found seductive voices have a negative effect on purchase intent, but more so on utilitarian products compared to hedonic ones. Men were more likely than women to respond positively to seductive and suave voices. Applying the results Voices are another way smart device companies can personalize their customers’ experiences. Garg says these companies should be aware that there may be a certain voice that will garner the best engagement. Their findings are not isolated to business, but may apply to other industries, such as the media. Garg says, for example, if publications intend to increase reader curiosity and engagement, they should use a female colloquial voice on “click to listen” features. Although not yet tested, Garg says he wouldn’t be surprised if their results extend to real-world settings with real human voices as well. During their research, Garg’s team asked participants if they had heard the advertisement voices before, and about 15 percent of respondents says they had. "These were voices we’d created for the first time,” Garg says. “If they say they’ve heard the voice before, that means they were thinking of them as human voices. Although we didn’t study it that way, I do believe what we’re seeing will be relevant for actual human being’s voices and interactions.” Having researched this for years, Garg says every time he listens to a voice, whether a customer service representative or podcast host, he questions whether or not it is impacting his behavior. A lot of times when I’m making a decision, I know that I’m making that decision passively because of the voice. “I’m acting 50 percent based on the rational information in the voice, but the other 50 percent I just want to listen more. There is an inherent desire for a certain voice.” Garg says his favorite part of the research are those “aha moments,” whether they be the influence of voice in his own life or in the industry—such as large companies using female voices in their products to draw engagement. He says he hopes to continue doing this kind of research to help startups and other companies perform better, as AI-powered voices continue to change the way people interact with technology and consume information. “We’re finding these interesting phenomena that can help create new products that are more effective,” Garg says. “I am trying to increase the economic surplus, in some ways to improve society, and this technology presents numerous opportunities.” Looking to know more?

• Leading scientist wins €2.2 million ERC Advanced Grant • The five-year project will explore early dementia interventions through understanding how an aquaporin water channel regulates glymphatic clearance • ERC Advanced Grant funding is amongst the most prestigious and competitive of the EU funding schemes. A world leading scientist in the College of Health and Life Sciences at Aston University has been awarded a €2.2 million ERC Advanced Grant to understand how the movement of a protein known as aquaporin-4 in the brain can help slow cognitive decline. The FORTIFY project, which will run for five years, is led by Professor Roslyn Bill in the School of Biosciences. She will apply her discovery of the movement of aquaporin-4 to understand how the cleaning mechanism in the brain works during sleep. The research will focus on how aquaporin-4 controls the glymphatic system, which is the mechanism that allows us to clear waste products from our brains while we sleep. Her hypothesis is that the movement of aquaporin-4 in the brain changes the effectiveness of this cleansing mechanism - which lessens as people age. A greater understanding of this process could lead to an early intervention treatment that could slow the onset of dementia, such as Alzheimer’s and Parkinson’s Diseases. ERC Advanced Grant funding is amongst the most prestigious and competitive of the EU funding schemes, providing researchers with the opportunity to pursue ambitious, curiosity-driven projects that could lead to major scientific breakthroughs. Professor Bill said: “Every three seconds someone in the world develops dementia and there is no cure. I want to stop that from happening. By understanding the molecular mechanisms of brain waste clearance, we have an opportunity to develop medicines that can slow the onset of dementia, very much in the same way that statins are prescribed to control heart disease”. Roslyn Bill discovered that the water channel protein aquaporin-4 increases the permeability of brain cells to water after a brain or spinal cord injury. Around 60 million people a year suffer such injuries following falls or accidents. For example, after a skiing accident in the French Alps in 2013, Michael Schumacher suffered a severe head injury. He was placed in a medically induced coma and underwent several surgeries to treat his injuries. Until now doctors have only been able to manage the symptoms of brain injury (swelling on the brain) through interventions that may require surgery. Professor Bill and her team are due to start clinical trials in summer 2023, to test a method to stop the swelling from happening in its tracks, building on her discoveries. Roslyn’s new ERC-funded project, FORTIFY, will focus on how aquaporin-4 controls fluid flow in the healthy, uninjured brain. In this round of Advanced Grants, the European Research Council (ERC) is awarding €544 million to 218 outstanding research leaders across Europe, as part of the Horizon Europe programme. The grants will support cutting edge research in a wide range of fields, from medicine and physics to social sciences and humanities. The grant is awarded to established, leading researchers with a proven track-record of significant research achievements over the past decade. The funding will enable the researchers to explore their most innovative and ambitious ideas. Mariya Gabriel, European Commissioner for Innovation, Research, Culture, Education and Youth, said: “ERC grants are a top recognition and a significant commitment from our best researchers. The €544 million funding puts our 218 research leaders, together with their teams of postdoctoral fellows, PhD students and research staff, in pole position to push back the boundaries of our knowledge, break new ground and build foundations for future growth and prosperity in Europe” Maria Leptin, ERC President, added: "These new ERC Advanced Grantees are a testament to the outstanding quality of research carried out across Europe. I am especially pleased to see such a high number of female researchers in this competition and that they are increasingly successful in securing funding. “We look forward to seeing the results of the new projects in the years to come, with many likely to lead to breakthroughs and new advances.”
Aston Institute for Forensic Linguistics (AIFL) is part of the project to infer authorship of uncredited documents based on writing style AIFL’s Professor Tim Grant and Dr Krzysztof Kredens are experts in authorship analysis Applications may include identifying counterintelligence risks, combating misinformation online, fighting human trafficking and even deciphering authorship of ancient religious texts. Aston University’s Institute for Forensic Linguistics (AIFL) is part of the AUTHOR research consortium which has won an $11.3 million contract to infer authorship of uncredited documents based on the writing style. The acronym stands for ‘Attribution, and Undermining the Attribution, of Text while providing Human-Oriented Rationales’. Worth $1.3 million, the Aston University part of the project is being led by Professor Tim Grant and Dr Krzysztof Kredens, who both are recognised internationally as experts in authorship analysis and who both engage in forensic linguistic casework as expert witnesses. In addition to their recognised general expertise and experience in this area, Professor Grant has specific expertise in using linguistic analysis to enhance online undercover policing and Dr Kredens has led projects to develop authorship identification techniques involving very large numbers of potential authors. The AUTHOR team is led by Charles River Analytics and is one of six teams of researchers that won The Human Interpretable Attribution of Text Using Underlying Structure (HIATUS) programme sponsored by the Intelligence Advanced Research Projects Activity (IARPA). The programme uses natural language processing techniques and machine learning to create stylistic fingerprints that capture the writing style of specific authors. On the flip side is authorship privacy - mechanisms that can anonymize identities of authors, especially when their lives are in danger. Pitting the attribution and privacy teams against each other will hopefully motivate each, says Dr Terry Patten, principal scientist at Charles River Analytics and principal investigator of the AUTHOR consortium. “One of the big challenges for the programme and for authorship attribution in general is that the document you’re looking at may not be in the same genre or on the same topic as the sample documents you have for a particular author,” Patten says. The same applies to languages: We might have example articles for an author in English but need to match the style even if the document at hand is in French. Authorship privacy too has its challenges: users must obfuscate the style without changing the meaning, which can be difficult to execute.” In the area of authorship attribution, the research and casework experience from Aston University will assist the team in identifying and using a broad spectrum of authorship markers. Authorship attribution research has more typically looked for words and their frequencies as identifying characteristics. However, Professor Grant’s previous work on online undercover policing has shown that higher-level discourse features - how authors structure their interactions - can be important ‘tells’ in authorship analysis. The growth of natural language processing (NLP) and one of its underlying techniques, machine learning, is motivating researchers to harness these new technologies in solving the classic problem of authorship attribution. The challenge, Patten says, is that while machine learning is very effective at authorship attribution, “deep learning systems that use neural networks can’t explain why they arrived at the answers they did.” Evidence in criminal trials can’t afford to hinge on such black-box systems. It’s why the core condition of AUTHOR is that it be “human-interpretable.” Dr Kredens has developed research and insights where explanations can be drawn out of black box authorship attribution systems, so that the findings of such systems can be integrated into linguistic theory as to who we are as linguistic individuals. Initially, the project is expected to focus on feature discovery: beyond words, what features can we discover to increase the accuracy of authorship attribution? The project has a range of promising applications – identifying counterintelligence risks, combating misinformation online, fighting human trafficking, and even figuring out the authorship of ancient religious texts. Professor Grant said: “We were really excited to be part of this project both as an opportunity to develop new findings and techniques in one of our core research areas, and also because it provides further recognition of AIFL’s international reputation in the field. Dr Kredens added: “This is a great opportunity to take our cutting-edge research in this area to a new level”. Professor Simon Green, Pro-Vice-Chancellor for Research, commented: “I am delighted that the international consortium bid involving AIFL has been successful. As one of Aston University’s four research institutes, AIFL is a genuine world-leader in its field, and this award demonstrates its reputation globally. This project is a prime example of our capacities and expertise in the area of technology, and we are proud to be a partner.” Patten is excited about the promise of AUTHOR as it is poised to make fundamental contributions to the field of NLP. “It’s really forcing us to address an issue that’s been central to natural language processing,” Patten says. “In NLP and artificial intelligence in general, we need to find a way to build hybrid systems that can incorporate both deep learning and human-interpretable representations. The field needs to find ways to make neural networks and linguistic representations work together.” “We need to get the best of both worlds,” Patten says. The team includes some of the world’s foremost researchers in authorship analysis, computational linguistics, and machine learning from Illinois Institute of Technology, Aston Institute for Forensic Linguistics, Rensselaer Polytechnic Institute, and Howard Brain Sciences Foundation.
Georgia Southern students expand communication disorder awareness amidst Deaf Culture Renaissance
At Georgia Southern, a group of students is taking courses to grow the number of interpreters in their communities and their fields. Each student comes to class with their own motivations to learn ASL. “Most of the deaf people, myself included, feel kind of depressed,” signed Angellia Burnett, a volunteer assistant in Georgia Southern University’s American Sign Language (ASL) course. “We miss a lot of things in life, because it has always been a struggle with communication.” Burnett grew up deaf, and is the only person in her family who is deaf. Members of her family speak ASL, but she said many in the Deaf community continue to be left out of family conversations because not everyone will sign all of the time. This leaves Deaf family members feeling isolated even within their own homes. “Not everyone accepts my deafness,” Burnett signed. “They need to know Deaf culture. They need to accept that.” One of the most effective ways of accepting someone is by understanding the challenges they face. Over the past few years, the world has experienced a Deaf culture renaissance, where the inclusion of people who are deaf becomes more mainstream. Recently, the film “CODA,” which stands for “children of deaf adults,” won the 2022 Academy Award for Best Picture. This brought Deaf culture further into the spotlight, opening many eyes into the lives of those with hearing impairments. “What that means is it embraces the entire community,” said Dana Taylor, Ph.D., Georgia Southern adjunct professor and sign language interpreter. “It’s not isolating one group as being different. Individuals get to see the struggles and challenges and the triumphs that people experience.” At Georgia Southern, a group of students is taking courses to grow the number of interpreters in their communities and their fields. Each student comes to class with their own motivations to learn ASL. Some are learning sign language because they have people in their lives with hearing impairments or other communication disorders where sign can be advantageous. Others are there to develop their Sign skills as a professional tool. “If I had a client who spoke ASL, I’d be able to communicate with them better or make them feel more comfortable,” said Ricki Botsford, speech pathology student. “I’ve learned a lot about how broad communication can be, because there are so many ways to communicate outside of the verbal option.” When the students were asked if they had tried learning other languages like Spanish or French, every hand was raised. When asked if they stuck to learning them, all but a few went down. So what makes Sign different? “It’s a lot easier to integrate into every day,” said Adia Greer who’s studying to be an athletic trainer for Deaf athletes. “I can speak it verbally, but I can also sign it. I’ve picked up signing to my cat a lot. She doesn’t understand it, but it allows me to practice.” While the students practice Sign with their pets and favorite TV shows, Burnett continues to come to class to help show her students the world they share, but not the one they see. Georgia Southern has a network of Student Accessibility Resource Centers on the Statesboro and Savannah campuses providing interpreters for students who want to attend classes and interact with their environment, as well as many other resources for students who are hard of hearing. “The whole world needs to learn Sign,” Burnett signed. “I want to see people motivated to learn. I see a lot of Hearing people who are motivated to learn, and a lot of Deaf people that want to help make them successful. I’m really proud that I can help in that.” If you're a reporter looking to know more about this important topic - then let us help with your coverage and stories.
