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.”

Study finds most cancer patients exposed to misinformation; UF researchers pilot 'information prescription'

Ninety-three percent of patients with a new cancer diagnosis were exposed to at least one type of misinformation about cancer treatments, a UF Health Cancer Center study has found. Most patients encountered the misinformation — defined as unproven or disproven cancer treatments and myths or misconceptions — even when they weren’t looking for it. The findings have major implications for cancer treatment decision-making. Specifically, doctors should assume the patient has seen or heard misinformation. “Clinicians should assume when their patients are coming to them for a treatment discussion that they have been exposed to different types of information about cancer treatment, whether or not they went online and looked it up themselves,” said senior author Carma Bylund, Ph.D., a professor and associate chair of education in the UF Department of Health Outcomes and Biomedical Informatics. “One way or another, people are being exposed to a lot of misinformation.” Working with oncologists, Bylund and study first author Naomi Parker, Ph.D., an assistant scientist in the UF Department of Health Outcomes and Biomedical Informatics, are piloting an “information prescription” to steer patients to sources of evidence-based information like the American Cancer Society. The study paves the way for other similar strategies. Most notably, the study found the most common way patients were exposed to misinformation was second hand. “Your algorithms pick up on your diagnosis, your friends and family pick up on it, and then you’re on Facebook and you become exposed to this media,” Parker said. “You’re not necessarily seeking out if vitamin C may be a cure for cancer, but you start being fed that content.” And no, vitamin C does not cure cancer. Health misinformation can prevent people from getting treatment that has evidence behind it, negatively affect relationships between patients and physicians, and increase the risk of death, research has shown. People with cancer are particularly vulnerable to misinformation because of the anxiety and fear that comes with a serious diagnosis, not to mention the overwhelming amount of new information they have to suddenly absorb. While past research has studied misinformation by going directly to the source — for instance, studying what percentage of content on a platform like TikTok is nonsense — little research has looked at its prevalence or how it affects people. The team first developed a way to identify the percentage of cancer patients exposed to misinformation. UF researchers collaborated with Skyler Johnson, M.D., at Huntsman Cancer Institute, an internationally known researcher in the field. The survey questions were based on five categories of unproven or disproven cancer treatments — vitamins and minerals, herbs and supplements, special diets, mind-body interventions and miscellaneous treatments — and treatment misconceptions. The myths and misconceptions were adapted from National Cancer Institute materials and included statements like “Will eating sugar make my cancer worse?” The team surveyed 110 UF Health patients diagnosed with prostate, breast, colorectal or lung cancer within the past six months, a time when patients typically make initial treatment decisions. Most had heard of a potential cancer treatment beyond the standard of care, and most reported they had heard of at least one myth or misconception. The most common sources were close friends or family and websites, distant friends/associates or relatives, social media and news media. The findings mark a shift in misinformation research, with major implications for the doctor-patient relationship, said Bylund, a member of the Cancer Control and Population Sciences research program at the UF Health Cancer Center. “I still think media and the internet are the source and why misinformation can spread so rapidly, but it might come to a cancer patient interpersonally, from family or friends,” she said. Most patients rarely discussed the potential cancer treatments they had heard about with an oncologist, the study also found. Next, the researchers plan to survey a wider pool of patients, then study the outcomes of interventions designed to decrease misinformation exposure, like the information prescription.

New AI tool matches students with high-impact internships

Finding the right internship can be an important step for students, but it’s not always clear which opportunities will lead to the strongest growth. To help solve that problem, University of Florida researchers have developed an AI-powered tool that helps students identify internships most likely to accelerate their technical and professional development. Unlike traditional recommendation engines, Pro-CaRE not only predicts which opportunities will lead to stronger outcomes, it also explains why each suggestion is a good fit. In testing data collected from the students, Pro-CaRE’s predictions proved highly accurate, accounting for more than 72% of the differences in learning gains among participants. While the pilot is being tested in engineering, the tool could be adopted for other disciplines. “Internships are one of the most critical parts of an engineering education, but students often struggle to know which experiences will actually help them grow,” said Jinnie Shin, assistant professor of research and evaluation methodology in the UF College of Education. “What makes Pro-CaRE unique is that it doesn’t just offer a list of options. It provides personalized recommendations backed by data and it tells students clearly why an opportunity is a good match for them.” Pro-CaRE creates matches by analyzing each student’s coursework, major, background and self-reported interest, confidence and self-efficacy in engineering skills. It then compares that profile with a carefully chosen set of similar peers to refine suggestions. The result is more precise guidance that adapts to students at different stages of their degree programs. “Students shouldn’t have to guess or hope that an internship will be worthwhile,” Shin said. “With Pro-CaRE, they can approach opportunities knowing they’re backed by evidence, whether the role is onsite, hybrid or remote and whether it’s at a startup or a Fortune 500 company.” The system is designed to work across a wide range of companies and contexts, giving students flexibility while ensuring their choices align with their personal and professional goals. Each recommendation comes with a clear “why this?” explanation, so students can make confident decisions and discuss options more effectively with advisors. Pro-CaRE was developed by a cross-disciplinary UF team combining expertise in education and engineering. Alongside Shin, the project’s co-principal investigators include Kent Crippen in the College of Education and Bruce Carroll in the Herbert Wertheim College of Engineering. The team is exploring external funding opportunities to expand the usage and test the efficacy on a larger scale. “Ultimately, our goal is to empower students to invest their time in experiences that will have the greatest impact,” Shin said. “Pro-CaRE bridges the gap between what students hope to gain and what internships can truly deliver.”

Using AI tools empowers and burdens users in online Q&A communities

Whether you’ve searched for cooking tips on Reddit, troubleshooted tech problems on community forums or asked questions on platforms like Quora, you’ve benefited from online help communities. These digital spaces rely on people across the world to contribute their knowledge for free, and have become an essential tool for solving problems and learning new skills. New research reveals that generative artificial intelligence tools like ChatGPT are creating a double-edge effect on users in these communities, simultaneously making them more helpful while potentially overwhelming them to the point of decreasing their responses. “On the positive side, AI helps users learn to write more organized and readable answers, leading to a noticeable increase in the number of responses,” explained Liangfei Qiu, Ph.D., study coauthor and PricewaterhouseCoopers Professor at the University of Florida Warrington College of Business. “However, when users rely too heavily on AI, the mental effort required to process and refine AI outputs can actually reduce participation. In other words, AI both empowers and burdens contributors: it enables more engagement and better readability, but too much reliance can slow people down.” The study examined Stack Overflow, one of the world’s largest question-and-answer coding platforms for computer programmers, to investigate the impact of generative AI on both the quality and quantity of user contributions. Qiu and his coauthor Guohou Shan of Northeastern University’s D’Amore-McKim School of Business measured the impact of AI on users’ number of answers generated per day, answer length and readability. Specifically, they found that users who used AI tools to generate their responses contributed almost 17% more answers per day compared to those who didn’t use AI. The answers generated with AI were both shorter by about 23% and easier to read. However, when people relied too heavily on AI tools, their participation decreased. Qiu and Shan noted that the additional cognitive burden associated with heavier AI usage negatively affected the impact on a user’s answer quality. For online help communities grappling with AI policies, this research provides valuable insight into how these policies can be updated in the current AI environment. While some communities, like Stack Overflow, have banned AI tools, this research suggests that a more nuanced approach could be a better solution. Instead of banning AI entirely, the researchers suggest striking a balance between allowing AI usage while promoting responsible and moderated use. This approach, they argue, would enable users to benefit from efficiency and learning opportunities, while not compromising quality content and user cognition. “For platform leaders, the takeaway is clear: AI can boost participation if thoughtfully integrated, but its cognitive demands must be managed to sustain long-term user contributions,” Qiu said.
