One AI-based advancement at a time, UF leaders are transforming the sports industry
As emerging technologies like AI reshape sport industries and professional demands evolve, it is essential for students to graduate with the expertise to thrive in their future careers. To ensure that these students are set up for success, the UF College of Health & Human Performance has launched a new sports analytics program. Led by Scott Nestler, Ph.D., CAP, PStat, a professor of practice in the Department of Sport Management and a national analytics and data science expert, the program ties back to the UF & Sport Collaborative – a five-part project intended to elevate UF’s presence on the global stage in sports performance, healthcare and communication. “Tools and insights that previously were only available to professional sports teams are now coming to the college level, and it makes sense for universities to begin using these data, technologies and new analytic methods,” Nestler said. The sports analytics program fosters collaboration between academic units, such as the Warrington College of Business and the University Athletic Association, helping bridge the gap between sport research and innovation and empowering students to address real-world challenges through data and AI. For example, the program offers opportunities to leverage technology and analytics for strategic decision making in player acquisition, team formation and in-game decisions. Beyond performance metrics, the program also explores marketing strategies and revenue analytics, providing a well-rounded understanding of the field. “When you have enough data and a large enough sample of individuals, AI can help make predictions that otherwise would take prohibitively longer for a human to accomplish with traditional methods,” said Garrett Beatty, Ph.D., the assistant dean for innovation and entrepreneurship and an instructional associate professor in the College of Health & Human Performance’s Department of Applied Physiology and Kinesiology. “Because those data volumes are getting so large, AI models, machine learning, deep learning and other strategies can be leveraged to make sense and glean insights from sport and human performance data in ways that have never been done before.” The program seeks to offer several educational opportunities, such as individual courses, certificate programs and potentially a full degree program. In the long term, Nestler envisions the program evolving into a center or institute, beginning with establishing a research lab in the spring. Additionally, the program will leverage the university’s supercomputer, HiPerGator, to analyze larger data sets and use newer predictive modeling machine learning algorithms. “As faculty and staff move from working with box score and play-by-play data to using tracking data, which contains coordinates of all players and the ball on the field or court tens of times per second, the size of data files in sports analytics has grown tremendously,” Nestler said. “HiPerGator, with its large storage capacity and multiple central processing units/graphic processing units, is ideal for using in sports analytics work in 2025.” Nestler also aims to increase student involvement by enhancing UF’s Sport Analytics Club and hiring research assistants to work on projects for the University Athletic Association. “We need to take a broader view of what AI is and realize that it incorporates a lot of what we’ve been calling data science and analytics in the form of machine learning models, which came more out of statistics and computer science. Those are types of AI and those that I think will largely continue to be used in the coming years within the sports space,” Nestler said. “Also, we’re continuing to see growth in the number of people interested in working in this space, and I don’t foresee that changing. Fortunately, we are also seeing the number of opportunities available to those with the appropriate skills increase as well.”
Trump’s Threat is His Destruction of the Republican Party
In All the King’s Men, Robert Penn Warren describes Willie Stark’s final victory. “And there wasn’t any Democratic party. There was just Willie, with his hair in his eyes and his shirt sticking to his stomach with sweat. And he had a meat ax in his hand and was screaming for blood.” Warren’s description is darkly poetic and metaphorical. Stark, the populist governor of a fictional state, did not murder his rivals, but he did destroy them, along with the political party he rode to power. Like Stark, Donald Trump has carved up the Republican Party of old, and in its place, there is just Trump. This is not the first time a politician has remade a political party, but the death of the G.O.P. threatens to unbalance our political system. We are defined by close elections, tight legislative majorities, and polarized preferences. Neither side in the cultural conflict can achieve core objectives, so the temptation to put more hope and power into the Executive, to skew the system, is mounting. We can argue about the degree to which past Republicans were truly restrained, especially in government spending, but at least the G.O.P. used to advocate for two seatbelts to keep the body politic safe from accidents: character to govern the self and constitutionalism to limit what government can do to others. As the G.O.P. grew to rival Democratic power, in the 1980s and 1990s, the New Deal coalition fractured, along with the assumption that simply more power, expertly applied, could solve our problems. Democrat Bill Clinton conceded “the era of big government is over.” Justice Elena Kagan recognized, “we’re all textualists now.” The tug of war between an evolving progressivism and a robust conservatism may not have made for an ideal way to solve problems, but it did encourage humility, born of the recognition that radical actions, even if successful, would be punished. Dr. Mark Caleb Smith serves as Professor of Political Science and the Director of the Center for Political Studies at Cedarville University. He teaches courses in American Politics, Constitutional Law, and Research Methodology/Data Analysis. His primary research interest is in the field of religion and American politics. View his profile Those days are over. Donald Trump’s Republicans are no longer a restraint of any kind. The seatbelts of the past have been snipped by the same leaders who claimed to buckle them in place. The Epstein Files are the exception of congressional pushback that proves the rule of the party’s degradation. But what of the appointment of unqualified and incompetent leaders in the F.B.I., H.H.S., Homeland Security, and the Department of Defense? Illegal and extra-judicial killings in the Caribbean? An unexplained and unauthorized military buildup in the same region? Shakedowns of universities and media outlets? Crypto corruption? Tariffs? Strong-arming law firms and firing career civil servants for seeking justice in our courts? The Republican response has mostly been crickets. There is no longer a major party that pretends to restrain the president through the law out of principle. The real disagreement between Trump Republicans and Biden Democrats is not about should the president abuse his power, but how. Unless something dramatic happens, the politics of the meat ax will come for us all. Mark is available to speak with the media regarding the state of politics in America.

VR Technology Offers Lessons in Navigating a Snow Squall
WCBS-TV, WPIX 11, and WNYW Fox 5 interviewed Dr. Jase Bernhardt, Hofstra associate professor of geology, environment, and sustainability, about his virtual reality program designed to teach the public about the danger of driving in a snow squall. Funded by a $100,000 Road to Zero Community Traffic Safety Grant from the National Safety Council, Dr. Bernhardt’s project emphasizes the importance of heeding emergency weather advisories and what drivers should do if they are on the road when a snow squall occurs. Users wear a headset and hold a device – like a video game controller – in each hand to replicate the movements of a steering wheel. Bernhardt’s collaborators include Assistant Professor of Sustainability Sasha Pesci; software developer Frank Martin ’22, ’23, who earned both a BS and an MS in Computer Science from Hofstra University; and John Banghoff and other meteorologists at the U.S. National Weather Service (NSW) Office, State College, PA.
Proteins, often called the building blocks of life, play a central role in drug development. When scientists develop new treatments, they must understand how drugs interact with proteins involved in disease mechanisms and with proteins in the human body that influence drug response. Scientists commonly use cryo-electron microscopy (cryo-EM) 3D imaging data to study proteins. While recent advances have enabled higher-resolution images that are easier to analyze, medium-resolution images—which are more difficult to interpret—are still the most common for larger protein complexes. Salim Sazzed, Ph.D., an assistant professor in the computer science department of Georgia Southern University’s Allen E. Paulson College of Engineering and Computing, has been awarded a two-year National Science Foundation grant of about $175,000 to lead a groundbreaking project to develop novel Artificial Intelligence (AI) techniques for determining protein secondary structures from medium-resolution cryo-electron microscopy (cryo-EM) images. Improved modeling from medium-resolution images will help researchers study more proteins efficiently, giving new insights into diseases and potentially guiding the development of new treatments and future drugs. At its core, this research will combine biology and machine learning to study protein structures. The multidisciplinary approach and potential impacts on public health are what most excite Sazzed. “The impetus behind this research is the positive impact on public health and possibly contributing to the biomedical workforce,” he said. “Seeing biology and computer science combine for that kind of impact is incredibly moving.” As the Principal Investigator (PI) for the project, Sazzed will use his expertise in deep learning computer models to focus on a major challenge in structural biology: identifying the two main secondary structures of proteins—the alpha helix and the beta sheet. These structures are critical for a protein’s overall shape and function, but in medium-resolution cryo-EM images they often appear indistinct or lack clear detail, making them particularly difficult to analyze. Sazzed’s research will focus on two main goals. First, he will quantify the variability of alpha helices and beta sheets in medium-resolution images, comparing them to idealized structures. Second, by integrating this structural variability with the image data in a deep learning model, he will aim to generate more precise and accurate representations of protein secondary structures. “When we feed this information into a deep learning model along with the image data, the model should be able to determine protein secondary structures more precisely,” Sazzed elaborated. Sazzed believes students will greatly benefit from this multi-disciplinary approach. In addition to a Ph.D. student, several undergraduate students will be directly engaged in the research. A full-day workshop will also be organized, allowing Georgia Southern students from diverse disciplines to participate. This initiative will build on Georgia Southern’s strong tradition of involving undergraduates in research and will support the University’s recent focus on biomedical and health sciences. “There are many different knowledge areas coming together in this work,” Sazzed said. “It involves computer science, biology, chemistry, and even public health. I look forward to students following the research and exploring these different fields themselves.” Allen E. Paulson College of Engineering & Computing Interim Associate Dean of Research, Masoud Davari, Ph.D., echoes this sentiment and emphasizes its importance to the University’s research profile. “Sazzed’s interdisciplinary research, which bridges the gap between biology and computer science, will foster multidisciplinary research in our college—as it is cutting-edge and potentially groundbreaking in drug development to impact people’s lives nationally and globally,” Davari said. “It’s also well aligned with the college’s strategic research plan—as we make the move to R1 status to be aligned with ‘Soaring to R1,’ which is among the transformational initiatives for the University.” Looking to know more about Georgia Southern University or connect with Salim Sazzed — simply contact Georgia Southern's Director of Communications Jennifer Wise at jwise@georgiasouthern.edu to arrange an interview today.
The University of Florida’s ‘AI Queen’ is using AI technology to help prevent dementia
To help the 50 million people globally who live with dementia, the National Institute on Aging is finding researchers to develop tech-based breakthroughs that target the disease — researchers like the University of Florida’s “AI Queen.” It’s a fitting nickname for Aprinda Indahlastari Queen, Ph.D., who is applying artificial intelligence technology to study transcranial direct current stimulation, or tDCS — a technique that involves placing electrodes on the scalp to deliver a weak electrical current to the brain — as a possible way to prevent dementia. The assistant professor in the UF College of Public Health and Health Professions’ Department of Clinical and Health Psychology is using UF’s supercomputer, HiPerGator, to perform neuroimaging and machine learning analyses to study how anatomical differences may affect tDCS outcomes. “Investigating working memory in patients with mild cognitive impairment offers an opportunity to understand how cognitive processes are disrupted in the early stages of Alzheimer’s disease,” said Queen, whose study — funded by a National Institute on Aging research career development grant — integrates neuroimaging with information on brain structure that is unique to older adults and those with mild cognitive impairment. Refining the treatment with AI Using neuroimaging, Queen captures real-time changes during tDCS to the parts of the brain associated with working memory, which is the type of memory that allows humans to temporarily keep track of small amounts of information. Think of this as a mental “scratchpad.” Her study includes older adults with mild cognitive impairment as well as individuals who are cognitively healthy. In tDCS, a safe, weak electrical current passes through electrodes placed on a person’s head. The stimulation is being used in research and clinical settings for a variety of conditions and has shown partial success as a nonpharmaceutical intervention that can improve cognitive and mental health in older adults. But tDCS results can vary across individuals, and the suspected cause is both simple and complex: Everyone’s head is different. “One potential reason tDCS may not work for some individuals is the variation in head tissue anatomy, including differences in brain structure,” Queen said. “Since electrical stimulation must travel through multiple layers of tissue to reach the brain, and every individual’s anatomy is unique, these differences likely affect outcomes.” To address this further, Queen is using AI. “Artificial intelligence will play a major role in the modeling pipeline, including constructing individualized head models, conducting predictive analyses to identify which participants will respond to the stimulation, and disentangling multiple individual factors that may contribute to these outcomes,” Queen said. An estimated 10 to 20% of adults over age 65 have memory or thinking problems characterized as mild cognitive impairment. Their symptoms are not as severe as Alzheimer’s disease and other dementias, but they may be at increased risk for developing dementia. “The fact that not all individuals with mild cognitive impairment progress to Alzheimer’s disease emphasizes the need to identify effective interventions that can slow the progression to dementia,” Queen said. “This project presents an opportunity to differentiate between multiple types of mild cognitive impairment and investigate how tDCS affects the brain across these subtypes.” An AI visionary Queen, who joined the UF faculty under the university’s AI hiring initiative, is an instructor in the College of Public Health and Health Professions’ undergraduate certificate program in AI and public health and health care, and the co-chair of the college’s AI Workgroup. She is also the assistant director for computing and informatics at the UF Center for Cognitive Aging and Memory Clinical Translational Research and a member of UF’s McKnight Brain Institute. Queen received her Ph.D. training in engineering with a focus on building and running computational models to investigate medical devices. She experienced a career “a-ha” moment as a postdoc, when she was a co-investigator on a large clinical trial that paired brain stimulation with cognitive training to enhance cognition in older adults. “This experience was transformative for me. I had the chance to interact directly with participants, which was both fulfilling and eye-opening. These interactions allowed me to see the immediate, real-world implications of my work and sparked a passion for pursuing aging research,” Queen said. “I realized that, through this type of research, I could have a more direct impact on addressing age-related challenges, which prompted a shift in my career plans.” The new grant will help Queen further improve her understanding of the neurobiology and progression of Alzheimer’s disease and other dementias. “These experiences will ultimately prepare me to become a well-rounded aging investigator, capable of making meaningful contributions to the field of aging research,” Queen said. She also credits her mentors and collaborators — Ronald Cohen, Ph.D.; Adam Woods, Ph.D.; Steven DeKosky, M.D.; Ruogu Fang, Ph.D.; Joseph Gullett, Ph.D.; and Glenn Smith, Ph.D. — with supporting her as an early career scientist. “It really takes a village to get here!” Queen said.

When it comes to transforming how organisations produce, consume, and reuse resources, Dr Luciano Batista, professor of operations management at Aston University, is a global pioneer. His research sits at the crossroads of innovation, digital transformation, and sustainability, tackling one of humanity’s most pressing challenges: our overconsumption of the planet’s resources. Reimagining the economy around renewal Dr Batista’s work focuses on circular supply chains —a model he helped establish at a time when 'closed-loop' systems dominated sustainability thinking. His early research laid the foundation for how businesses could move beyond recycling and linear take-make-dispose models, instead designing systems that reuse, restore, and regenerate. View his profile here From theoretical frameworks to real-world applications, his studies—such as comparative analyses of circular systems implemented by Tetra Pak in China and Brazil—demonstrate the measurable economic and environmental benefits of circularity in action. His 2022 Emerald Literati Award-winning paper introduced a methodology for mapping sustainable alternatives in food supply chains, earning international recognition for its real-world impact. A global voice for industrial symbiosis and circular innovation The influence of Dr Batista’s work reaches far beyond academia. He has advised the European Commission’s Circular Cities and Regions Initiative (CCRI) and contributed insights to policymakers through the UK All-Party Parliamentary Manufacturing Group. His expertise continues to inform national and regional strategies for sustainable production and industrial symbiosis —where one company’s waste becomes another’s resource. Today, he extends that impact globally as a visiting professor at the Massachusetts Institute of Technology (MIT), conducting research at the MIT Center for Transportation & Logistics on circular supply chain innovations, supported by Aston University’s study-leave programme. He also mentors future leaders in sustainability as part of Cambridge University’s Institute for Sustainability Leadership (CISL). Driving the next wave of sustainable transformation Looking ahead, Dr Batista is spearheading collaborations through Aston’s Centre for Circular Economy & Advanced Sustainability (CEAS), working with the Energy & Bioproducts Research Institute (EBRI) and West Midlands Combined Authority (WMCA) on projects developing biochar-based clean energy systems for urban districts. He is also advancing the social dimension of the circular economy—ensuring that the move toward sustainable production is inclusive and equitable. His Symposium on the Socially Inclusive Circular Economy, held at the 2025 Academy of Management Conference, has sparked new international research partnerships with Monash University (Australia) and the Vienna University of Economics and Business. A vision for a regenerative future At the heart of Dr Batista’s work is a simple but urgent truth: humanity is consuming resources at a rate our planet cannot sustain. Through his research and global collaborations, he is helping organisations, policymakers, and communities move toward a future where growth and sustainability coexist. “The transition to a circular economy is not optional—it is essential,” says Dr Batista. “Our goal must be to redesign systems that allow people, businesses, and ecosystems to thrive together.”
How UF researchers are helping Floridians to build resilience
When Hurricane Idalia hit the Big Bend region of Florida in 2023, Jeff Carney and his team were watching. A coalition of architects, planners, and landscape architects led by Carney worked closely with the tiny Gulf island of Cedar Key, which is particularly vulnerable to hurricanes, to prepare for this moment. The researchers had modeled for city officials how a major storm would flood the city’s core services. “Idalia caused flooding exactly where the maps said it would, including city hall, the historic downtown, older homes, and many streets,” Carney said. After the storm, Cedar Key moved city hall to higher ground, as outlined in the plan. And just in time. Barely a year later, Cedar Key was hit even harder by Hurricane Helene. Between the storms, Carney’s group had worked with the city to refine their storm preparation. The new plan focused more on resilience-boosting projects, like improving drainage around the city. Cedar Key finalized their plans just weeks before Helene. “A lot of the projects we put forward in this plan are in the process of seeking additional funding after Helene,” Carney said. A professor of architecture at the University of Florida, Carney directs the Florida Institute for Built Environment Resilience, or FIBER. A research institute in UF’s College of Design, Construction and Planning, FIBER engages with communities to understand how the designs of buildings and cities expose Floridians to risks — not just storms, but also excessive heat, poor air quality, even a lack of health care. FIBER faculty then work with cities to mitigate these hazards. By preparing for emergencies, upgrading buildings, and providing targeted services, communities across Florida are bolstering the resilience of their residents, all with expert help from UF researchers. Preparing to weather big storms That kind of resilience is especially important for some of Florida’s most vulnerable residents. Older and poorer Floridians face higher-than-average risks from natural disasters and other environmental hazards. That vulnerability was apparent in Cedar Key as it weathered the last two hurricane seasons. Centered around aquaculture and tourism, Cedar Key seems in many ways to be thriving. Yet, with the feel of a small fishing village, roughly 13% of its nearly 1,000 full-time residents are considered to be financially disadvantaged, according to U.S. Census data. Poorer residents may also have a harder time walking away from coastal communities devastated by storms. With savings invested into damaged homes and jobs tied to the local area, less-wealthy residents often have no choice but to stay and rebuild. Carney’s team helps people see the opportunities for rebuilding with a clearer vision of a future where rising sea levels are a reality. “You capture people’s attention and excitement when you can offer them options that are not doomsday,” said Carney, who has been working in Pine Island and Matlacha in Southwest Florida’s Lee County to help residents affected by recent storms prepare for the future. “There’s a lot of opportunity for rebuilding as long as you don’t try to have it be business as usual. We help people see how redevelopment can provide a community asset for the future,” he added. “We try to paint the picture of all the possible scenarios so people can find their own comfort level. It puts them in the driver’s seat.” Aging with fewer choices While that kind of agency is empowering, it can be harder to come by as people retire and find themselves facing tough decisions on fixed incomes. That’s a common experience in Florida, which has a larger proportion of seniors than any other state, due in part to its popularity as a retirement destination. More than 10% of Americans over the age of 65 live below the federal poverty line. This population often finds themselves moving to less safe places as they age. “Older people with more social vulnerability — such as low income or poor health — have a tendency to move to worse places,” said Yan Wang, Ph.D., a professor of urban and regional planning in the UF College of Design, Construction and Planning. “They are more likely to move to places with less economic stability, with less access to health care, and with more exposure to extreme weather.” Wang and postdoctoral researcher Shangde Gao, Ph.D., recently published a study that uncovered the risks low-income seniors face when moving. Compared to their peers with higher incomes, poorer seniors were more likely to end up in neighborhoods lacking access to health care facilities. To address these kinds of disparities, UF Health has launched mobile health units that can reach people who have trouble traveling to health centers, including low-income seniors. The Mobile Outreach Clinic provides primary care and referrals for specialists. And the newly launched cancer screening vehicle, which serves all of North Central Florida, can help catch the disease in the early stages when it is easiest to treat. It’s not just finding health care that’s a struggle. Older adults from minority racial groups were also more likely to increase their exposure to poor air quality and to natural disasters like flooding and hurricanes when they moved, Wang and Gao discovered. “If we understand the trend and causes of these income disparities better, we could better prepare some places with more health care resources or better hurricane preparation for these older populations,” Wang said. Building safer, healthier homes That preparation is happening right now in Jacksonville, not just for big storms but for the everyday nuisances and hazards — even the ones people are exposed to in their own homes — that threaten people’s lives and health. The Jacksonville Restore and Repair for Resiliency research initiative was founded to address these kinds of risks while improving energy efficiency. The R3 initiative, as it’s known, is a home remodeling program organized by a slew of community partners and supported by FIBER research on the impact of housing quality on health. The project aims to keep longtime residents of the Historic Eastside in their homes while addressing the home hazards that put people at risk for medical complications like asthma attacks and emergency room visits. “The designs of buildings impact human health and well-being,” said Lisa Platt, Ph.D., the lead researcher with the Jacksonville program and an assistant professor of interior design with FIBER. “Our research is helping the team prioritize the home improvements that will benefit residents’ health the most.” Jacksonville’s Eastside faces a lot of challenges. The population is older than the city as a whole. Roughly three-quarters of residents are over the age of 60, and the poverty rate is over 40%. Yet more than a third of residents own their own homes. Often passed down from previous generations, some of the houses are now over a century old and struggle to keep the intense Florida heat and humidity out. Platt’s research has modeled how things like high heat days — only growing more common in a warming world —are associated with increased emergency room use and poor perceived physical and mental health. That science helps guide the community partners to prioritize providing air conditioning and better insulation to protect Historic Eastside residents. To date, the Jacksonville program is targeting up to 70 homes for renovation. Builders have fixed holes in roofs, replaced drafty windows, and hooked up air conditioning for the first time, keeping the heat and humidity at bay and protecting residents’ health. Now the R3 initiative is applying for federal grants to expand the program. “I think the best way to approach this kind of community action research is with humility and outreach. Community members have amazing expertise. I always say, ‘I can build models to analyze the problem, but you are the ones that are the experts,’” Platt said. “That’s where UF can be most useful, is coming in from a perspective of service.”
Five Million Airbnb Reviews Illuminate Guests’ Crime and Safety Concerns
Concerns about crime and safety have a dramatic impact on the behavior of Airbnb customers, according to new research co-authored by Liad Wagman, Ph.D., Dean of the RPI Lally School of Management. In an analysis of nearly 5 million reviews left by Airbnb guests, Wagman and his colleagues found that a short-term rental property’s occupancy rate and rental price dropped by significant amounts after a guest left a review mentioning safety concerns at or around the property: occupancy rates fell by anywhere from 1.5 to 2.4 percent, while average nightly prices dropped by roughly 1.5 percent. These negative safety reviews influenced the behavior not only of potential future customers, but also of the people who wrote them. A customer who mentioned concerns about crime and safety in the neighborhood around a property, for instance, became 60 percent less likely to ever use Airbnb again. “To see the effect of these dynamics play out in action is always fascinating to me," Wagman said. “Given that humans have different preferences, and that information transmittal is imperfect, it’s unsurprising that the effect of self-experience is larger than that of reading a critical review that resulted from it.” Worries about safety within a property — say, a broken step or a slippery tub — also reduced customers’ willingness to return to the platform, but by a more modest amount. The study also found that when people with neighborhood safety concerns did return to the platform, they tended to book properties in areas with lower rates of crime. The study, co-authored by Aron Culotta of Tulane, Ginger Zhe Jin of the University of Maryland, and Yidan Sun of Binghamton University, was published in the journal Marketing Science. Overall, the researchers found that safety-oriented reviews were rare: only about 0.5 percent of customer reviews mentioned safety concerns. But those reviews tend to be more negative in sentiment than the typical customer review, giving them an outsize impact on the behavior of subsequent would-be customers. The findings illustrate a delicate balancing act digital platforms have to perform, particularly those that rely heavily on user reviews: while highlighting negative experiences can help consumers make more informed choices, too much emphasis can drive customers away completely. The team ran several simulations calibrated by their empirical analysis to test how these dynamics play out in the market. They found that if a platform suppressed negative safety reviews completely, customers might assume that safety information was being hidden, and become more wary of using the platform in general. Conversely, while more transparency around safety issues could lead to fewer bookings of impacted properties in the short term, in the long run such a policy could boost user trust and draw more people to the platform, offsetting the short-term losses. “Platforms with the competitive space to focus on long-term objectives may benefit from a higher level of transparency, which can be facilitated by making information that is relevant to their buyers’ decision-making more readily available,” Wagman said. “Doing so facilitates trust and helps incentivize sellers to work to improve the quality of their offerings, as well as help shape sellers' decisions to enter a market (e.g., offer their listings) in the first place.”
