Major wildfires are once again raging in California, this time in Los Angeles County. According to news reports, they have so far been responsible for two deaths, 1,000 damaged structures and the evacuation of more than 30,000 residents. Experts from the University of Delaware's Disaster Research Center can comment on health impacts, evacuation strategies and how to manage pets and animals during disasters.


Below are three of the Disaster Research Center core faculty and the topics they can discuss related to the current wildfires:


Jennifer Horney, founding director of UD’s epidemiology program: Health impacts of disasters (mental and physical) as well as evacuation. Additionally, exposure to wildfire smoke which increases risk of respiratory infections; the scale of these fires during a very high period for these infectious diseases (flu, RSV, COVID) may also put pressure on public health and health care systems.


Tricia Wachtendorf, co-director of the Disaster Research Center and professor of sociology and criminal justice: Disaster donations, social vulnerability and evacuation.


Sarah DeYoung, associate professor of sociology and criminal justice: Pets and animals during evacuations.

Expert: Meta ditches fact checking, a major loss for the American people

Meta moving away from fact-checking towards a "community notes" model is the equivalent of crowd-sourcing truth, says the University of Delaware's Dannagal Young. This shift in policy is a victory for intuition, common sense and lived experience over data, expertise and evidence. It also stands as another example of media institutions acting preemptively to avoid political and economic fallout under the incoming administration. Young, director of UD's Center for Political Communication and professor of communication, can talk about epistemology (how people understand the world) and how it relates to populism and populist leaders like incoming President Donald Trump. Young can also discuss the following: • The contents of Meta CEO Mark Zuckerberg's announcement video, in which he explains that recent elections mark a "cultural tipping point" in the direction of "free speech." "He's acknowledging that this policy change isn't a principled stance Meta is now taking, as much as a response to what he thinks the public is calling for (a dubious conclusion to draw from a narrow electoral victory)," Young said. • Zuckerberg's new stance, and how it will allow him to curry favor with the incoming administration because it allows Meta to avoid having to moderate Trump-friendly content. • Why content moderation and fact checking are expensive, and how moving away from that model is a "WIN-WIN-WIN for Meta: politically, culturally, and economically. And a LOSE LOSE LOSE for the American people: socially, culturally, and democratically," Young said.

New Year's Resolutions: Why they fail and how we can stick to them

By now, most people have already made their New Year's resolutions and (hopefully) put them into practice. But most people — about 90% — give up on them within the first few weeks of the year. University of Delaware experts dig into the psychology behind why resolutions fail and offer a recipe for success. The timing of New Year’s resolutions also isn’t always ideal. According to Philip Gable, professor in the Department of Psychological and Brain Sciences, a lack of commitment is one reason why many people fail to achieve their goals. “New Year's resolutions sometimes lack in commitment,” he said. “It's just this time of year when people feel like they should make a resolution, as opposed to other times in the year when it's less common but maybe more meaningful, like if you get a doctor's report and realize you need to change that aspect of your life.” In order to be part of the 10% of people who keep their New Year’s resolutions, Gable said to break down big goals into small, achievable steps. “I think a lot of times with goals, people will commit to a very big goal and not realize the smaller steps they need to take to achieve that goal,” Gable said. “If we have too big of a goal, we get emotionally distressed when we can't do it, or we fail because we set too big of a goal. Or maybe we couldn't think through all of the elements required to meet that really big goal. So starting small gives us something achievable, and then that gives you a platform to go to the next thing.” Naomi Sadeh, associate professor in the Department of Psychological and Brain Sciences at the University of Delaware, said that part of the reason it’s so hard to make long-term changes is that humans are wired to prioritize instant gratification over delayed rewards. In other words, when posed with an option, we tend to pick the easy choice with an immediate outcome to satisfy a need today instead of delaying gratification for a bigger reward — we splurge on items we don’t really need instead of saving money, order takeout instead of cooking a healthy meal, or binge-watch a TV show instead of going to the gym. “With impulsivity and with breaking New Year's resolutions, often it's when people tend to opt for that sooner, smaller reward over the longer, bigger reward,” Sadeh said. “The sooner reward is really tempting, even if it's not as satisfying in the long run as the longer goal or bigger goal that you had.” When people set goals, they tend to feel very motivated for a few days and falsely assume they’re committed to their goal. But as soon as that motivation wears off, they give up. “There's potentially a mismatch in the timing of your goals,” said Rob West, interim chair and professor in the Department of Psychological and Brain Sciences. “Your goals are immediate, they're conscious, they're volitional. You have those in the moment, and they can be developed and abandoned quickly. But habits take a considerable amount of time and repetition.” To connect directly with Gable, visit his profile and click on the connect button.

Exploring language as an early behavioral marker of Alzheimer's Disease

Professors from the University of Delaware and Carnegie Mellon University will use a $3.7 million RF1 grant from the National Institute on Aging (NIA) to examine language as an early behavioral marker of Alzheimer’s Disease. If successful, this research could pave the way for earlier interventions. “Identifying these individuals as early as possible gets them into preventive treatments sooner,” said Alyssa Lanzi, assistant professor of Communications Sciences & Disorders at UD. The study builds on pilot data gathered by Anna Saylor, a third-year doctoral student in the communication sciences and disorders doctoral program, housed in the UD's College of Health Sciences. “We know a lot about how language develops in childhood but not much about how it changes in older adults,” Saylor said. “Our data suggest subtle language changes might signal future cognitive decline.” To explore these changes on a larger scale, Lanzi is collaborating with MacWhinney, who founded TalkBank, open science database of language samples. Within TalkBank is DementiaBank, a shared database of multimedia interactions for studying communication in dementia. However, DementiaBank is outdated and limited in demographics, and the quality and rigor of the data need improvement. Lanzi is seeking to change that. Her five-year study seeks 300 older adults aged 60-90 nationwide from underrepresented backgrounds or populations vulnerable to health disparities. “Current DementiaBank data is representative of Caucasians of a higher socioeconomic status,” Lanzi said. “We must intentionally recruit people who are at the greatest risk — for example, adults who are Black, Asian, Hispanic, Latin and those living in rural areas.” The recruitment strategy, rooted in community engagement at locations in Wilmington, Delaware, is part of the novelty of Lanzi’s grant. “This is a feasibility study to see if our approach in Wilmington can be replicated in other states,” Lanzi said. Lanzi has also established an advisory committee of nationwide faculty with relevant expertise on specific priority populations. Their input will tailor plans to population needs while data is collected through a central site at UD. The Delaware Center for Cognitive Aging Research (DECCAR) also provides critical infrastructure for the study. “This project is an example of the success of DECCAR, and our impact extends far beyond state lines,” said Lanzi, an executive committee member with DECCAR. Participants selected for the study will participate in a comprehensive cognitive and language testing battery via telehealth, so they don’t have to travel to UD’s campus, which is novel and unique to this study. “To study their language, they’ll see pictures and be asked to describe them and share stories from their past,” Lanzi said. Study participants will receive a gift card for participating and feedback about their memory to share with their healthcare provider. “Building trust and giving back are key elements of our strategy,” Lanzi said. Lanzi is already preparing for the next phase of her research, supported by an additional $800,000 grant from the NIA. This phase will test the effects of an online treatment Lanzi developed for individuals identified as at risk. “If we find that language is an early marker of disease, I want to take this research to the next level and develop treatments that teach strategies to enhance independence and improve the quality of life for those at risk of developing dementia,” she said.
