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 However, DementiaBank is outdated and limited in demographics, and the quality and rigor of the data need improvement.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.

Tariffs fuel global sourcing shakeup for fashion in the U.S.

Be prepared to see more Made in Vietnam or Made in Bangladesh labels on clothing in the coming years. That’s because U.S. fashion companies are rethinking their global sourcing strategies and operations in response to the Trump administration’s trade policies and tariffs, according to new research by the University of Delaware's Sheng Lu. Lu, professor and graduate director in the Department of Fashion and Apparel Studies, partners with the United States Fashion Industry Association (USFIA), on an annual survey of executives at the top 25 U.S. fashion brands, retailers, importers and wholesalers doing business globally. Members include well-known names like Levi’s, Macy’s, Ralph Lauren and Under Armour, among others. The report covers business challenges and outlook, sourcing practices and views on trade policy. “We wear more than just clothes; we wear the global economy, the supply chain and the public policies that jointly make fashion and affordable clothing available to American families,” Lu said. “We want to know where these companies source their products and what factors matter to them the most. It’s a classic question and it evolves each year.” This year’s report, released on July 31, shows tariffs and protectionist policies are the top business challenge for companies, with nearly half reporting declining sales and more than 20% saying they have had to lay off employees. This was followed closely by uncertainty around inflation and the economy, increasing sourcing and production costs, and changes in trade policies from other countries. In response, more than 80% of companies said they will diversify the countries from which they source their products, focusing on vendors in Asian countries such as Vietnam, Bangladesh, Cambodia and Indonesia. Despite the push for “Made in USA” garments, only 17% of respondents plan to increase sourcing from the U.S. Lu shared his findings in the following Q&A: What surprised you about the survey results? Two things surprised me. First, contrary to common perception, the results do not indicate that the tariff policy so far has effectively supported or encouraged more textile and apparel production in the U.S. This actually makes sense. U.S. mills are as uncertain about the tariff rates as our trading partners are. A U.S. company may manufacture the clothes here, but use yarns, fabrics and zippers from other countries. When tariffs drive up the cost of these raw materials, it reduces the price competitiveness of apparel “Made in the USA.” Many domestic factories are in a “wait and see” mode, holding back on making critical investments to expand production due to the lack of a clear policy signal. Second, I was struck by the wide-ranging impact of the tariffs, which has gone far beyond what I originally imagined. Tariffs have not only increased U.S. fashion companies’ sourcing costs but have also affected their product development, shipping and overall supply chain management. Nearly 70% of the survey respondents said they have delayed or canceled some sourcing orders due to tariff hikes. Should consumers be prepared for less variety in clothing or shortages? Later this year, we may see fewer clothing items from our favorite brands on store shelves — especially during the holiday shopping season — and many of those items may come with a higher price tag. That said, fashion companies are doing what they can to avoid passing on tariff costs across the board, as they recognize that consumers are price sensitive. Many surveyed U.S. fashion companies say they intend to strengthen relationships with key vendors as a strategic move, and there is a growing public call for U.S. companies to provide more support and resources to their suppliers in developing countries. Sustainability is a huge issue in the fashion industry, as millions of tons of textiles end up in landfills every year. Companies say they are spending less on sustainability efforts. What would you tell companies about their sustainability efforts? Our survey suggests that sustainability can open up new business opportunities for U.S. fashion companies. Respondents said that when sourcing clothing made from sustainable fibers — like recycled, organic, biodegradable and regenerative materials — they are more likely to rely on a U.S. sourcing base or suppliers in the Western Hemisphere. In other words, even if apparel “Made in the USA” or nearby cannot always compete on price with lower-cost Asian suppliers, there is a better chance to compete on sustainability. Based on what I’ve learned from our Gen Z students — who expect better quality and more sustainable products if they have to pay more, and are critical consumers for many brands and retailers — it is unwise to hold back on investments in sustainability. What do you see as the biggest takeaway from the survey? One key takeaway is that the $4 trillion fashion and apparel business today is truly “made anywhere in the world and sold anywhere in the world.” In such a highly global and interconnected industry, everyone is a stakeholder — meaning there are no real winners in a tariff war. The study is also a powerful reminder that fashion is far more than just creating stylish clothing. Today’s fashion industry is deeply intertwined with sustainability, international relations, trade policy and technology. I hope the findings will be timely, informative and useful to fashion companies, policymakers, suppliers and fellow researchers. I plan to incorporate the insights, as well as the valuable industry connections developed through my long term partnership with USFIA, in my classroom, giving UD students fresh, real-world perspectives on the often “unfashionable” but essential side of the industry.

Hiring Gen Z: What employers keep getting wrong

As with any new generation entering the workforce, Gen Z possesses unique tools and strengths but also experiences challenges trying to land that first job where Millennials, Gen X-ers and Baby Boomers are doing the hiring. University of Delaware career expert Jill Gugino Panté can talk about how employers can address gaps in the hiring process and communication issues as they relate to a generation that prioritizes work with purpose, authentic connections and work-life balance. Panté, director of the Lerner Career Services Center at the University of Delaware, pointed to the following three areas that should be prioritized: • Transparency. Gen Z wants to feel special and appreciates individual attention, Panté said. Employers should make the hiring process transparent and respond to emails. During busy times, they should use an out of office message that states when they will respond. • Clarity. Make details about salary, benefits, flexibility, skill building and career advancement clear. These details should be on a company's careers page so that candidates have a good understanding of what they can expect. Clarity in job postings is also important: It doesn’t make sense that an entry level position requires more than two years of experience. Don’t call it entry level if it’s not entry level. • Communication mistakes. Be transparent with Gen Z candidates about the process and timeline. More importantly, stick to that process. If a change is made, they should communicate it immediately. Also, employers should be authentic in their communication. If the process is taking longer than expected or they haven’t communicated effectively, employers should acknowledge it instead of continuing to ghost applicants.
