Sun-Sentinel: What happens when parents go beyond sharenting?

So many parents routinely share photos and news about their kids on social media that the behavior has a name: sharenting. Usually harmless and well-meaning, it can also take a dangerous turn, exposing children to online predators, allowing companies to collect personal information and creating pathways for children to become victimized by identity theft. The risks are most pervasive when parents overshare to profit from their social media accounts. Whenever parents share, they are the gatekeepers, tasked with protecting their children’s information, but they are also the ones unlatching the gates. When parents profit from opening the gates, it is especially challenging to balance protecting their kids’ privacy against sharing their stories. Federal and state laws typically give wide deference to parents to raise their children as they see fit. But the state can and does intervene when parents abuse their children. Those laws protect children in the physical world. However, few laws shield children when parents risk harming them online. Let’s consider this hypothetical situation based on a composite of real-life events. Mia (fictional name) is a 7-year-old girl growing up in Orlando. Her mother is a stay-at-home parent who has a public Instagram account and considers herself an influencer. Many lingerie brands pay Mia’s mom to model their clothing. When a lingerie company from overseas offers Mia’s mom some money to have Mia also pose in their clothing, Mia’s mom says yes. Over the next few weeks, Mia and her mom model the clothing together in pictures and videos, sometimes wearing the outfits while reading together in bed, having pillow fights or being playful around the house — always in clearly intimate but arguably appropriate settings. Mia’s mom’s social media page explodes with new followers, many of whom appear to be grown men. The images on the page receive hundreds of likes and multiple comments. Mia’s mom deletes the most inappropriate comments but leaves others, hoping to increase engagement. As Mia’s mom’s social media following grows, so does the amount of money she earns. Mia tells her teacher about the social media page. Her teacher reaches out to Mia’s parents, to no avail. Mia’s mom keeps sharing. The teacher sees this as a potential form of abuse and neglect and, according to her obligation as a mandatory reporter of abuse, she calls in a report to the state’s central abuse registry. The teacher isn’t trying to get Mia’s mom in criminal trouble, but she thinks the family could use some education surrounding safe social media use and possibly access to financial support if they need this type of online exposure to pay the bills. The intake counselor declines to accept the hotline call. The counselor explains that the posting of pictures is not grounds for an abuse, abandonment or neglect investigation. The parent is sharenting, the counselor says, and that is within a parent’s right. Of course, child sexual abuse material is illegal, but the photos posted by Mia’s mom fall into a gray area — not illegal material, but likely harmful to Mia. Should there be a law to stop this? I believe there should be. Just as our views regarding child abuse have evolved, so must our views on sharenting. Merely 150 years ago, it was legal for parents to beat their children. It wasn’t until 1874, when a little girl named Mary Ellen was beaten severely by her caregiver, that courts began to step in. Drawing from existing laws prohibiting animal cruelty, the Society for the Prevention of Cruelty to Animals argued that Mary Ellen had the right to be free from abuse. At the time, there were laws protecting animals from harm by their caregivers but no laws protecting children from such harm! Back to the present: Mia’s disclosure to her teacher could have changed her life and led to her family getting online safety help, if only the child welfare laws were suitably tailored to protect her in the online world as they attempt to do offline. Child protection laws should be expanded to include harms that can be caused by online sharing. The law can both protect parental autonomy and honor children’s privacy through a comprehensive and multidisciplinary new approach toward protecting children online — one that allows for thoughtful investigation, education, remediation and prosecution of parents who use social media in ways that are significantly harmful to their children. This conduct, which falls beyond sharenting, is ripe for legal interventions that reset the balance between a parent’s right to share and a child’s right to online privacy and safety. Stacey Steinberg grew up in West Palm Beach and now lives in Gainesville, where she is a professor at the University of Florida Levin College of Law; the supervising attorney for the Gator TeamChild Juvenile Law Clinic; the director of the Center on Children and Families; and the author of “Beyond Sharenting,” forthcoming in the Southern California Law Review.

Listen: Donald Trump Loathes the Courts. He’s Following the Autocrat Playbook to Sideline Them

This article is republished from The Conversation under a Creative Commons license. Read the original article here. In democratic systems, the courts are a vital check on a leader’s power. They have the ability to overturn laws and, in Donald Trump’s case, the executive orders he has relied on to achieve his goals. Since taking office, Trump has targeted the judiciary with a vengeance. He has attacked what he has called “radical left judges” and is accused of ignoring or evading court orders. The Supreme Court has already handed the Trump administration some key wins in his second term. But several cases now before the court will be pivotal in determining how much power Trump is able to accrue – and what he’ll be able to do with it. As Paul Collins, a Supreme Court expert from the University of Massachusetts Amherst, explains in episode 4 of The Making of an Autocrat: It’s all about presidential power. And that’s really significant because it’s going to enable the president to basically inject a level of politics into the federal bureaucracy that we frankly haven’t really seen before in the US.

Maduro is gone; expert details potential impact on the Caribbean

Globally, the ousting of Nicolás Maduro in Venezuela has been met with a mix of reactions and cautious optimism. The University of Delaware’s Kalim Shah can discuss how regime change will play across the Caribbean and the spillover effect that will ripple throughout the region – and the world – in the years and decades to come. Shah, professor of energy and environmental policy and an expert on the island nations of the Caribbean, says that although public statements have been muted and restrained, there is a shared understanding. “For small island states that have absorbed the effects of Venezuelan collapse for more than two decades, this moment represents the possible end of a long and destabilizing chapter,” Shah said. Caribbean governments are not celebrating regime change, Shah said. Rather, they are responding to the prospect of reduced systemic risk. “A Venezuela that no longer exports large-scale displacement, opaque energy leverage and permissive criminal governance is objectively preferable for the region.” Shah can discuss several aspects of Venezuela’s political history, how the nation has arrived where it is, where it might be headed and the impact this will have on the Caribbean as a whole. Those include: • Venezuela’s political and economic deterioration during the Chávez–Maduro era and how that has translated directly into pressures felt across the Caribbean in the form of migration, fiscal exposure, security risks and regional uncertainty. • How the nation’s institutional collapse coincided with deepening organized crime activity across the Caribbean basin. Data from the United Nations Office on Drugs and Crime consistently places the region within major cocaine trafficking corridors linking South America with North American and European markets. For Caribbean governments, this meant higher interdiction costs, increased exposure to transnational criminal networks and growing pressure on already limited security institutions. • This moment invites a reassessment of China’s expanding footprint in the Caribbean, Shah says. He can discuss the ways in which Beijing has deepened its presence throughout the region. Shah says that as this transition unfolds, five policy developments will determine whether the cautious optimism proves warranted: • The impact on Venezuelan outward migration to the Caribbean. • Whether Caribbean public systems receive durable support rather than short-term humanitarian fixes. • Organized crime and drug trafficking pressures in the Caribbean basin. • External security engagement in the Caribbean. • Whether the region avoids a return to dependency-driven energy and infrastructure politics. “For the Caribbean, hope today is not naïve. It is conditional. The Chávez–Maduro years imposed real costs on the region. Their end creates an opening…but only if policy follows through,” Shah said.

The health challenges astronauts Butch Wilmore and Suni Williams face after 9 months in space

On June 5, 2024, astronauts Butch Wilmore and Suni Williams embarked on a brief mission to the International Space Station. But equipment failures turned what was supposed to be an eight-day trip into a grueling 9 month spaceflight. This week, Wilmore and Williams finally returned to Earth. While their safe return is cause for celebration, the journey doesn’t end when astronauts touch down on Earth. They now face the significant task of recovering from the physical and psychological toll of long-duration spaceflight. As part of the University of Florida’s ongoing research into astronaut health, Rachael Seidler, Ph.D., a leading expert in spaceflight-associated health changes, is studying the long-term effects of space travel on astronauts’ brains and bodies. Seidler’s research focuses on understanding how the central nervous system and brain structure adapt to the challenges of space travel, as well as how these changes affect performance, balance, and mobility once astronauts return to Earth. “While the physical and psychological challenges astronauts face after returning from long-duration space missions are well-documented, the research we do at UF is helping us understand the intricacies of their recovery process,” said Seidler, deputy director of the Astraeus Space Institute at UF. “By following astronauts like Butch and Suni before, during, and after their missions, we can track how the human body responds to the extreme conditions of space.” Behavioral and Brain Changes Post-Flight Seidler’s research tracks astronauts’ physical and neurological recovery by observing them both during their missions and after they return. "One of the most immediate challenges astronauts face when they return to Earth is mobility and balance. These issues often recover more quickly compared to others, but it takes time for astronauts to readjust to gravity,” Seidler said. "The balance, mobility, and walking difficulties astronauts experience during the first weeks back are typically resolved in a short period, but brain function and structure require longer recovery periods." Seidler’s research indicates that astronauts’ brains exhibit compensation when they return to Earth following spaceflight. This compensation occurs through the recruitment of additional neural pathways in order to return to their preflight performance levels. However, the recovery of brain function is a gradual process. "This brain functional compensation is typically no longer observed within one to six months post-flight," Seidler said. However, not all changes are reversible. "Brain structural changes, particularly related to fluid shifts in space, show little to no recovery even after six months to a year," Seidler said. Two significant structural changes include the brain physically sitting higher in the skull and the expansion of the brain’s ventricles — fluid-filled cavities in the brain — which can increase in volume by 25% or more. These changes are thought to result from the fluid shifts caused by microgravity, and they present long-term health considerations for astronauts. Long-Term Health Effects: Understanding the Impact As Wilmore and Williams embark on their recovery journey, the long-term impact of these changes becomes a critical focus for researchers like Seidler. "The long-term health impacts are crucial to understand because they could affect how astronauts recover and perform in their daily lives post-mission," she said. Seidler’s team at UF is conducting a new study in which they are tracking astronauts for up to five years post-flight to better understand these long-term effects. "We’ve had astronauts in space for up to a year, and we know how to manage their physical health during those missions," Seidler said. "But the effects of space on the brain and body extend beyond the mission, and our work helps inform strategies to manage recovery." Collaborating with NASA and Studying Spaceflight-Associated Neuro-Ocular Syndrome Seidler's work is also part of a broader collaboration with NASA and other scientists to assess astronaut long-term health. The project is particularly focused on Spaceflight-Associated Neuro-Ocular Syndrome, which affects up to 70% of astronauts. This condition involves structural changes to the eye and optic nerve, leading to vision problems that may impact astronauts’ function. "Neuropsychological assessments can help to measure astronauts’ brain health, while studies of the ocular system help identify potential vision issues that may arise during and after long-duration space missions," she said. Simulating Space Conditions on Earth In addition to studying astronauts on Earth and in space, Seidler’s team conducts experiments to simulate the effects of spaceflight on human physiology. The UF lab runs experiments in head-down tilt bed rest studies, which keep participants lying down for weeks to months at a time to simulate the lack of gravity. "This type of study helps us understand how fluid shifts in the body during space travel affect mobility, balance, and brain structure," Seidler explained. "In addition, other publications have reported that astronauts describe that vestibular galvanic stimulation feels similar to what they experience when they first arrive in space and when they return to Earth. We have equipment to induce these effects in the lab." Looking Toward the Future As space missions continue to grow longer and more complex, UF’s research is more important than ever. "We’re studying these issues now to ensure that future astronauts are prepared for the physical and cognitive challenges that await them in deep space," Seidler said.

Researchers work to reduce excessive noise in Florida cities

Excessive noise, or noise pollution, in cities has been linked in multiple studies to increased stress, sleep disturbances, and long-term health problems. Researchers from the University of Florida are on a mission to quiet things down, working with local governments and a private firm to improve both public health and urban living. Enter Martin Gold, an associate professor from UF’s School of Architecture, and his team of students. They recently partnered with Siebein Acoustic, a soundscape design firm that specializes in architectural and environmental acoustics. The team visited Fort Lauderdale, one of Florida’s busiest cities, known both as a party destination and a mecca for retirees. The team studied areas throughout downtown and by the beach to provide recommendations for reducing the impact of sound in the city at large. To inform their work, researchers recruited participants to walk the city and report on their observations about sound and sights, took photo documentation, acoustic measurements, geographical measurements and analyzed municipal code studies. The team proposed different improvement strategies including: Using vertical distance by requiring residential high-rise construction to limit residences in the lower floors of buildings. Limiting sound levels at windows or balconies of residential units. Building envelope systems, which are the building components that separate the indoors from the outdoors, that limit sound transmission and absorb sound. Designing new construction so buildings absorb and diffuse the sounds striking them rather than reflecting and subsequently amplifying the sounds or focusing the sounds in particular areas. Strategic zoning to incentivize designs along arterial corridors that fill the sites and provide acoustic barriers to the residential neighborhoods behind them. “We need to take a closer look at how we are designing the next generation of urban environments. There’s a lot we can do with soundscape architecture to positively impact issues moving forward.” —Martin Gold, associate professor from UF’s School of Architecture The findings and recommendations were presented at the International Congress and Exposition on Noise Control Engineering in Nantes, France. Gold and his students are currently surveying an area of Clearwater and plan to study more cities around the state and offer recommendations for reducing noise.

A Snapshot of the Local Economy: Simon Medcalfe on Growth, Risk, and What Comes Next

At Augusta University’s annual Economic Forecast Breakfast hosted by the James M. Hull College of Business, Simon Medcalfe, PhD, offered a grounded, data-driven look at how the local economy is performing — and what lies ahead. Speaking to business leaders, students and community stakeholders, Medcalfe emphasized the importance of distinguishing real economic growth from inflation-driven gains, noting that while the Augusta region continues to grow, it does so at a measured pace compared to national averages. His presentation framed the local economy as stable and resilient, but not immune to broader forces shaping the U.S. outlook. A key theme of Medcalfe’s remarks was the role of research, innovation and education in sustaining long-term economic health. He pointed to strong gains in research and development across Georgia and highlighted how university-based research directly contributes to regional economic output. According to Medcalfe, investment in knowledge creation remains one of the most reliable drivers of growth, reinforcing the value of higher education institutions as economic anchors. Simon Medcalfe, PhD, is an economist with an emphasis on sports economics, social determinants of health, and the local economy. View his profile At the same time, Medcalfe cautioned against complacency. While regional fundamentals remain solid, he stressed that uncertainty at the national level continues to pose risks. “However, uncertainty abounds in national macroeconomic policy that could negatively impact growth next year,” Medcalfe said, underscoring how unresolved fiscal decisions and policy shifts can ripple down to local economies. Still, his overall outlook balanced realism with optimism. Medcalfe concluded that the Augusta region — and Georgia more broadly — is positioned to weather uncertainty thanks to diversification, investment in early education, and continued research activity. “Overall, Augusta and Georgia are positioned well for economic growth in 2026 with a strong commitment to early childhood education, a diversified labor market and strong research and development,” he said.

My MBA Journey at 69: Because Apparently, Climbing Everest Base Camp Wasn't Enough

If you watched CBS 60-Minutes host, Cecilia Vega set out on a challenging 10-day trek to Everest Base Camp (EBC) in the Himalayas, for last week's episode, you couldn't help but marvel at the gruelling physical demands and the profound experience of being at the foot of Mount Everest.  Her journey, which involved intense training, navigating dangerous suspension bridges, and dealing with extreme altitude, also highlighted the massive industry around Everest and the vital, underappreciated role of the Sherpa community.  Her journey is an inspiring look at how we can push our own boundaries.  Bravo Cecilia! Vega described hiking Everest Base Camp as "the hardest thing I've ever done physically," battling low oxygen (like breathing through a straw) and fatigue, despite months of training.  She experienced sub-freezing temperatures, crossed dizzying suspension bridges, and even witnessed close calls with avalanches, with trusty Sherpas conducting nightly tent checks to ensure her safety. Hiking to Everest Base Camp is hard.  I know.  Because I did it.  At 60 Let me explain. I have a tradition of celebrating milestone birthdays with a bang. When I turned 60, I gave myself six physical challenges — one for each decade lived. The grand finale? Climbing to Everest Base Camp. It was epic, exhausting, and left me with both altitude sickness and lifetime bragging rights. But as I approached 69, I craved something different. Not hiking boots this time — just highlighters. Not mountain peaks — mental peaks. I wanted an intellectual challenge that would prove my brain still had some miles left on it. No oxygen tanks required this time. Just caffeine, reliable Wi-Fi, and an iron will. How I Got Here (And Why I'm Questioning My Sanity) I've always wanted an MBA — partly for the knowledge, but let's be honest, mostly for the prestige. There's something irresistible about joining that club of spreadsheet-loving scholars. For years, I've imagined myself casually tossing around terms like "synergy" and "stakeholder engagement" while sipping something expensive in a sleek business lounge. What I didn't imagine was attempting this after a 46-year hiatus from university. Spoiler alert: It's harder than I thought. Like, significantly harder. Enter the MBA: Twenty-four courses. Two years or so, and approximately one hundred "What was I thinking?" moments. I enrolled at the Sprott School of Business at Carleton University, which offers a generous seniors' discount. I briefly debated whether to ask for the student discount or the seniors' discount — then thought, why not request both? I've earned these wrinkles and this tuition bill. Bonus perks: I qualify for the student medical and dental plans. My classmates use them for wisdom tooth extractions. I'm eyeing the denture clause. Term One: The Tech Tsunami Let's talk about the software situation.  Brightspace. Turnitin. eProctor. Excel (the betrayer). Word. APA 7th Edition. And about a dozen other platforms that might as well have been written in Klingon. I expected a gentle introduction — maybe some academic foreplay before diving into heavy coursework. Instead, I was shoved into the deep end with weights tied to my ankles. Each assignment came with a forest's worth of readings, PowerPoint slides, and discussion board posts. I was up at 5 a.m., trying to squeeze in extra hours in the day. (Spoiler: you can't.) Despite decades spent managing teams, I was barely scraping 60% on quizzes — the open-book ones. How is that even possible? Accounting became my personal Everest. People kept telling me, "Excel is your friend." That's a lie. Excel is that friend who borrows your car, crashes it, returns it on empty, and then asks if you've bothered reading the manual. Casualties of War: Family, Friends, and Dottie My family was neglected. My friends assumed I'd entered witness protection. Even my little dog Dottie stopped talking to me. She'd give me this look — a devastating combination of pity and disappointment — every time I said, "Sorry, no walk today. Mommy has to study debits and credits." You haven't experienced true shame until you've been judged by a 10-pound dog wearing a sweater. The Breaking Point (And the Breakthrough) I'll admit it — I had serious moments where quitting felt like the only rational option. The workload was relentless. The jargon was endless. The pressure was overwhelming. I contacted teaching assistants, professors, and even the university librarian, desperately searching for a lifeline. They were all kind and patient. But ultimately, I had to figure it out myself. And somewhere between the caffeine highs and APA citation lows, something clicked. Even Cs get Degrees! By midterm, I began to suspect something radical: perhaps the large amount of work was the real test. Not the material itself, but the sheer volume. Maybe this was the school's way of differentiating dedicated students from curious ones, the serious from the casual observers. Was it possible that the secret to MBA success was learning what not to do? After all, the passing grade is a B- (70%). At this point in my life, I'd be happy with a 71% and a full night's sleep. Hence the title, Even Cs get Degrees! Working Smarter, Not Harder Somewhere between week three and mild hysteria, I made a radical decision: stop trying to do everything. I focused on lectures and study notes instead of drowning in supplementary readings. I prioritized assignments strategically. I stopped pretending perfection was achievable — or necessary. The results were immediate: • My grades improved • My panic attacks decreased • Dottie started making eye contact again I also began scheduling regular Zoom calls with professors and TAs — not just for assistance, but to foster genuine relationships (my lifelong superpower). Once I stopped pretending, I had everything under control; everything truly improved. School life has improved. Home life has also improved. I was finally able to brush my hair again. Slowing Down to Soak It In Next term, I'm taking just one course. Because honestly, what's the rush? I'm not chasing a promotion or striving for a corner office. I'm doing this for myself — for the simple joy of learning and the satisfaction of knowing I still can.  I want to enjoy the journey, not rush through it gasping. I want to look forward to lectures rather than fear them. I want my sleep score (and my sanity) restored.  The goal isn't speed. It's savouring. What I've Learned So Far Here's what these first two courses have taught me: ✓ I can still learn — even when my brain occasionally reboots mid-sentence  ✓ I can focus — especially with enough coffee ✓ I'm still gloriously, endlessly curious ✓ I need sleep (The 5 a.m. club can keep their membership) ✓ I need fun (Revolutionary concept, I know) ✓ I love to learn (Turns out, I always have) ✓ I make mistakes — and they're not terminal ✓ I need help — and I must ask for it ✓ APA 7th Edition is real — and I finally understand what it means (Sort of. Mostly. Sometimes.) ✓ Even Cs or, in my case, a B- get a Degree — consistent, sustainable B- work will win most every race Looking Ahead: The Big 7-0 By the time I graduate, I'll be at least 70 years old. And honestly? I can't think of a better birthday gift for myself. When most people talk about slowing down, I'm actually ramping up. While others are downsizing, I'm uploading assignments at 11:58 p.m. When my friends ask why I do this, I smile and say: "Because I still want to know what I'm capable of." To Be Continued... This is just the beginning of my MBA adventure. I've completed two courses out of twenty-four. Twenty-two more to go — one term at a time, one course at a time, one small victory at a time. I'll update this blog periodically with new stories, fresh insights, and probably more tales of Dottie's disappointment. As We Start the New Year Here's a toast to all of us who refuse to act our age. To everyone starting something new — whether it's an MBA, a marathon, or a pottery class.  To everyone who believes it's never too late to learn, to laugh, or to start again.  Because learning doesn't stop when you retire. Sometimes, it's only just beginning. Stay tuned for Term Two updates, where I'll tackle another course, hopefully retain my sanity, and continue proving that 69 is just a number (and so is 70, 71, 72...).

AI-driven software is 96% accurate at diagnosing Parkinson's

Existing research indicates that the accuracy of a Parkinson’s disease diagnosis hovers between 55% and 78% in the first five years of assessment. That’s partly because Parkinson’s sibling movement disorders share similarities, sometimes making a definitive diagnosis initially difficult. Although Parkinson’s disease is a well-recognized illness, the term can refer to a variety of conditions, ranging from idiopathic Parkinson’s, the most common type, to other movement disorders like multiple system atrophy Parkinsonian variant and progressive supranuclear palsy. Each shares motor and nonmotor features, like changes in gait — but possess a distinct pathology and prognosis. Roughly one in four patients, or even one in two patients, is misdiagnosed. Now, researchers at the University of Florida and the UF Health Norman Fixel Institute for Neurological Diseases have developed a new kind of software that will help clinicians differentially diagnose Parkinson’s disease and related conditions, reducing diagnostic time and increasing precision beyond 96%. The study was published recently in JAMA Neurology and was funded by the National Institutes of Health. “In many cases, MRI manufacturers don’t communicate with each other due to marketplace competition,” said David Vaillancourt, Ph.D., chair and a professor in the UF Department of Applied Physiology and Kinesiology. “They all have their own software and their own sequences. Here, we’ve developed novel software that works across all of them.” Although there is no substitute for the human element of diagnosis, even the most experienced physicians who specialize in movement disorder diagnoses can benefit from a tool to increase diagnostic efficacy between different disorders, Vaillancourt said. The software, Automated Imaging Differentiation for Parkinsonism, or AIDP, is an automated MRI processing and machine learning software that features a noninvasive biomarker technique. Using diffusion-weighted MRI, which measures how water molecules diffuse in the brain, the team can identify where neurodegeneration is occurring. Then, the machine learning algorithm, rigorously tested against in-person clinic diagnoses, analyzes the brain scan and provides the clinician with the results, indicating one of the different types of Parkinson’s. The study was conducted across 21 sites, 19 of them in the United States and two in Canada. “This is an instance where the innovation between technology and artificial intelligence has been proven to enhance diagnostic precision, allowing us the opportunity to further improve treatment for patients with Parkinson’s disease,” said Michael Okun, M.D., medical adviser to the Parkinson’s Foundation and director of the Norman Fixel Institute for Neurological Diseases at UF Health. “We look forward to seeing how this innovation can further impact the Parkinson’s community and advance our shared goal of better outcomes for all.” The team’s next step is obtaining approval from the U.S. Food and Drug Administration. “This effort truly highlights the importance of interdisciplinary collaboration,” said Angelos Barmpoutis, Ph.D., a professor at the Digital Worlds Institute at UF. “Thanks to the combined medical expertise, scientific expertise and technological expertise, we were able to accomplish a goal that will change the lives of countless individuals.” Vaillancourt and Barmpoutis are partial owners of a company called Neuropacs whose goal is to bring this software forward, improving both patient care and clinical trials where it might be used.

UF professor to expand proven disease-prediction dashboard to monitor Gulf threats

After deploying life-saving cholera-prediction systems in Africa and Asia, a University of Florida researcher is turning his attention to the pathogen-plagued waters off Florida’s Gulf Coast. In the fight to end cholera deaths by 2030 – a goal set by the World Health Organization – UF researcher and professor Antar Jutla, Ph.D., has deployed his Cholera Risk Dashboard in about 20 countries, most recently in Kenya. Using NASA and NOAA satellite images and artificial intelligence algorithms, the dashboard is an interactive web interface that pinpoints areas ripe for thriving cholera bacteria. It can predict cholera risk four weeks out, allowing early and proactive humanitarian efforts, medical preparation and health warnings. Cholera is a bacterial disease spread through contaminated food and water; it causes severe intestinal issues and can be fatal if untreated. The US Centers for Disease Control reports between 21,000 and 143,000 cholera deaths each year globally. Make no mistake, the Cholera Risk Dashboard saves lives, existing users contend. His team now wants to set up a similar pathogen-monitoring and disease-prediction system for pathogenic bacteria in the warm, pathogen-fertile waters of the Gulf of America. “Its timeliness, its predictiveness and its ease of access to the right data is a game changer in responding to outbreaks and preventing potentially catastrophic occurrences.” - Linet Kwamboka Nyang’au, a senior program manager for Global Partnership for Sustainable Development Data Closer to home Jutla is seeking funding to develop a pathogen-prediction model to identify dangerous bacteria in the Gulf to warn people – particularly rescue workers – to use protective gear or avoid contaminated areas. He envisions post-hurricane systems for the Gulf that will help the U.S. Navy/Coast Guard and other rescue workers make informed health decisions before entering the water. And he wants UF to be at the forefront of this technology. “If we have enough resources, I think within a year we should have a prototype ready for the Gulf,” said Jutla, an associate professor with UF’s Engineering School Sustainable Infrastructure and Environment. “We want to build that expertise here at UF for the entire Gulf of America.” Jutla and his co-investigators have applied for a five-year, $4 million NOAA RESTORE grant to study pathogens known as vibrios off Florida’s West Coast and develop the Vibrio Warning System. These vibrios in the Gulf can cause diarrhea, stomach cramps, nausea, vomiting, fever and chills. One alarming example is Vibrio vulnificus, commonly known as flesh-eating bacteria, a bacterium that often leads to amputations or death. The Centers for Disease Control and Prevention (CDC) has reported increases in vibrio infections in the Gulf region, particularly from 2000 to 2018. The warm and ecologically sensitive Gulf waters provide a thriving habitat for harmful pathogens. “The grant builds directly on the success of our cholera-prediction system," Jutla noted. "By integrating AI technologies into public health decision-making, we would not only lead the nation but also become self-reliant in understanding the movement of environmentally sensitive pathogens, positioning ourselves as global leaders.” Learning from preparing early Jutla’s dashboards are critical tools for global health and humanitarian officials, said Linet Kwamboka Nyang’au, a senior program manager for Global Partnership for Sustainable Development Data. “Its timeliness, its predictiveness and its ease of access to the right data is a game changer in responding to outbreaks and preventing potentially catastrophic occurrences,” Kwamboka Nyang’au said. Over the last few years, Jutla and several health/government leaders have been working to deploy the cholera-predictive dashboard. “Our partnership with UF, the government of Kenya and others on the cholera dashboard is a life-saving mission for high-risk, extremely vulnerable populations in Africa. By predicting potential cholera outbreaks and coordinating multi-stakeholder interventions, we are enabling swift action and empowering local governments and communities to prevent crises before they unfold,” said Davis Adieno, senior director of programs for the Global Partnership for Sustainable Development Data. The early warnings for waterborne pathogens also allows the United Nations time to issue early assistance to residents in the outbreak’s path, said Juan Chaves-Gonzalez, a program advisor with the United Nations’ Office for the Coordination of Humanitarian Affairs. “There are several things we do with the money ahead of time. We provide hygiene kits. We repair and protect water sources. We start chlorination, we set up hand-washing stations, train and deploy rapid-response teams. At the community level, we try to inject funding to procure rapid-diagnostic tests,” he said. “We identify those very, very specific barriers and put money in organizations’ hands in advance to remove those barriers.” Eyes on the Gulf In the United States, hurricanes stir up vibrios in the Gulf, posing a high risk of infection for humans in the water. There has been a nearly 200% increase in these cases over the last 20 years in the U.S., according to the CDC. “After Hurricane Ian, we saw a very heavy presence of these vibrios in Sarasota Bay and the Charlotte Bay region. Not only that, but they were showing signs of antibiotic-resistance. Last year, we had one of the largest number of cases of vibriosis in the history of Florida,” Jutla said. Samples from 2024 hurricanes Helene and Milton are being analyzed with AI and complex bioinformatics algorithms. “If there is a risky operation by rescue personnel, not using personal protective equipment, then we would want them to know there is a significant concentration of these bacteria in the water,” Jutla said. “As an example, Navy divers operating in contaminated waters are at risk of infections from vibrios and other enteric pathogens, which can cause severe gastrointestinal and wound infections.” Safety and economics “Exposure to vibrios and other enteric pathogens,” Jutla added, “can disrupt economic activities, particularly in coastal regions that are dependent on tourism and fishing. And vibrios may be considered potential bioterrorism agents due to their ability to cause widespread illness and panic.” In developing the Vibrio Warning System, Jutla noted, he and his team want to significantly enhance public health safety and preparedness along the Gulf Coast. By leveraging advanced AI technologies, satellite datasets and predictive modeling, they plan to mitigate the risks posed by environmentally sensitive pathogenic bacteria, ensuring timely interventions and safeguarding human health and economic activities. “Hospital systems and healthcare providers in the Gulf region will have a tool for anticipatory decision making on where and when to anticipate illness from these environmentally sensitive vibrios, and issue a potential warning to the general public,” he said. “With the potential to become a leader in environmental pathogen prediction, UF stands at the forefront of this critical research, poised to make a lasting impact on local, regional, national and global health and safety.”

Chasing followers makes crypto traders perform worse on social investment sites

Whether excited about gaining new followers or desperate to win back lost subscribers, investors who saw changes to their subscriber count performed worse than before their subscribers changed, according to a new study. The research tracked performance on social investment sites, where individuals can trade assets like cryptocurrency while attracting audiences based on their performance — like YouTube, but for investments. Both gaining and losing followers led investors to make more frequent, riskier trades. The upshot is that traders performed about 10% worse in the weeks after their subscriber counts changed. “If the number of followers increases a lot, it creates an overconfidence effect. You are more aggressive in trading, and your future trading performance will be worse,” said Liangfei Qiu, Ph.D., a professor in the University of Florida’s Warrington College of Business and co-author of the new study. “So logically we thought that if more followers leads to worse performance, then if we reduce the number of followers, it will reverse the effect, reduce overconfidence and lead to higher trading performance,” Qiu said. “But that’s not what we found. If we reduce the number of followers, they trade even more aggressively and their trading performance becomes even worse.” Qiu and his collaborators at the University of Maryland and University of Washington worked directly with an anonymous social trading platform to examine the impact of gaining or losing followers on traders’ cryptocurrency trading behavior and performance. The research revealed the power of social pressure. This study was focused on cryptocurrency, which is highly volatile and may exacerbate the risk of social trading. But social trading also exists for traditional investments like stocks and bonds, and chasing followers could hurt these types of investments, too. The researchers say that both platforms and investors should guard against the downsides. “If platforms emphasize the social functions too much, it might backfire. Eventually it will hurt the long run performance of the platform,” he said. “The investors should realize their inherent bias and make sure their trading strategies are not too affected by social attention.”
