Institutional Repository

The UDSpace Institutional Repository collects and disseminates research material from the University of Delaware.

  • Faculty, staff, and graduate students can deposit their research material directly into UDSpace. Faculty may use UDSpace to fulfill the University of Delaware Faculty Senate Open Access Resolution, and in many cases may use it to fulfill open access requirements from grant funding agencies.
  • Departments can use UDSpace to publish or distribute their working papers, technical reports, or other research material.
  • UDSpace also includes all doctoral dissertations from winter 2014 forward, and all master's theses from fall 2009 forward.

The use of clothing as a mood enhancer and its effect on mental health in emerging adults in Canada during a global pandemic
(International Textile and Apparel Association Annual Conference Proceedings, 2024-01-23) Wenderski, Malgosia; Jung, Jaehee; Wasilewski, Julia
The advent of the COVID-19 pandemic had disrupted lifestyles and diminished mental health. It was unclear if emerging adults continued their high engagement with clothing during the peaks of the pandemic. The relationship between clothing, mood, and mental health was also unknown. This study surveyed 574 emerging adults in Canada and investigated how the pandemic had affected both clothing engagement and the use of clothing as a mood enhancer, and how this relationship impacted mental health. The study found that greater fear of COVID-19 predicted and positively correlated with fashion involvement and altering mood through clothing. Individuals reported multiple motivations to enhance mood through clothing, including bolstering the self-concept, self-esteem, and comfort. Therefore, clothing facilitated coping among emerging adults in Canada. No relationship was found between mood enhancement and mental health. Future research is encouraged to further explore and clarify the relationship between clothing, mood, and mental health.
The Impact of Sea Level Rise on Roadway Design and Evacuation Routes in Delaware
(American Journal of Climate Change, 2024-03-29) Palevich, Jack; Faghri, Ardeshir; Karakurt, Ahmet
As the global temperature continues to increase, the sea level continues to rise at a rapid rate that has never been seen before. This becomes an issue for many facets of life but one of the most impacted is the transportation infrastructure. Many people living in low elevation coastal areas can become trapped by flooding with no way in or out. With Delaware being a coastal state, this would affect a large portion of the population and will have detrimental effects over time if nothing is done to combat sea level rise. The issue with sea level rise in transportation is that once the roads become flooded, they become virtually unusable and detour routes would be needed. If all the roads in a coastal area were to be affected by sea level rise, the options for detours would become limited. This article looks at direct solutions to combat sea level rise and indirect solutions that would specifically help transportation infrastructure and evacuation routes in Delaware. There is not one solution that can fix every problem, so many solutions are laid out to see what is applicable to each affected area. Some solutions include defense structures that would be put close to the coast, raising the elevation of vulnerable roads throughout the state and including pumping stations to drain the water on the surface of the road. With an understanding of all these solutions around the world, the ultimate conclusion came in the form of a six-step plan that Delaware should take in order to best design against sea level rise in these coastal areas.
Bias of AI-generated content: an examination of news produced by large language models
(Scientific Reports, 2024-03-04) Fang, Xiao; Che, Shangkun; Mao, Minjia; Zhang, Hongzhe; Zhao, Ming; Zhao, Xiaohang
Large language models (LLMs) have the potential to transform our lives and work through the content they generate, known as AI-Generated Content (AIGC). To harness this transformation, we need to understand the limitations of LLMs. Here, we investigate the bias of AIGC produced by seven representative LLMs, including ChatGPT and LLaMA. We collect news articles from The New York Times and Reuters, both known for their dedication to provide unbiased news. We then apply each examined LLM to generate news content with headlines of these news articles as prompts, and evaluate the gender and racial biases of the AIGC produced by the LLM by comparing the AIGC and the original news articles. We further analyze the gender bias of each LLM under biased prompts by adding gender-biased messages to prompts constructed from these news headlines. Our study reveals that the AIGC produced by each examined LLM demonstrates substantial gender and racial biases. Moreover, the AIGC generated by each LLM exhibits notable discrimination against females and individuals of the Black race. Among the LLMs, the AIGC generated by ChatGPT demonstrates the lowest level of bias, and ChatGPT is the sole model capable of declining content generation when provided with biased prompts.

Director networks and firm value
(Journal of Corporate Finance, 2024-02-13) Bakke, Tor-Erik; Black, Jeffrey R.; Mahmudi, Hamed; Linn, Scott C.
Are the professional networks of directors valuable? To separate the effect of director networks on firm value from the effect of other value-relevant director attributes, we use the unexpected deaths of directors as a shock to the director networks of interlocked directors. By studying the announcement returns and using a difference-in-differences methodology, we find the negative shock to director networks reduces the value of interlocked firms – a result that is stronger for firms that are more likely to benefit from access to information from board connections. This evidence is consistent with director networks being valuable and improving access to information.
