Evolution Of Regulatory Pathways In Vibrio Fischeri Strains Impacts Biofilm Phenotypes And Symbiotic Capacity And Curriculum Interventions Differ In Their Impact On Microbiology Utility Value In Nursing Students, Jennifer Calawa

Doctoral Dissertations

Vibrio fischeri strains vary in their capacity to form mutualisms with animal hosts such as the Hawaiian bobtail squid Euprymna scolopes, yet these differences are often not explained by phylogeny. Successful colonization requires biofilm production, which is tightly controlled by a complex network of two-component system regulators including hybrid histidine kinases BinK and RemK, as characterized in the model symbiont strain ES114. Divergence in biofilm network architecture or regulatory logic may lead to strain-specific differences in biofilm formation, limiting symbiotic potential. Part I of this work investigates genetic divergence underlying reduced colonization capacity in strain H905, a planktonic isolate and …

Mindreading And Embodiment: Beyond Mirror Neurons., Sanad Al Khatib

College of Arts & Sciences Senior Theses

This paper examines the question: how do we figure out what other people are thinking and why they act as they do, or put differently, how is it that we can read minds in daily life? For decades, the dominant view held that we explain and predict other people’s behavior by attributing to them mental states such as beliefs, desires, and intentions, represented symbolically in the brain. The embodied simulation model challenges this view, proposing that understanding others primarily relies on mirror neurons that activate both when we perform an action and when we observe someone else performing it. This …

What Does Genius Look Like? Investigating Brilliance Bias In Ai-Generated Images, Juliana Shihadeh, Margareta Ackerman, David Loker

Computer Science and Engineering

Text-to-image models, like Midjourney, DALL-E, and Stable Diffusion, have been shown to reinforce harmful biases, often perpetuating outdated and discriminatory stereotypes. In this study, we delve into a particular bias largely overlooked in generative image research: Brilliance Bias. By age 6, many children begin to internalize the damaging notion that intellectual brilliance is a male trait—a belief that persists into adulthood. Our findings demonstrate that popular image AI models possess this bias, further entrenching the misguided notion that exceptional intelligence is inherently male. This study calls for addressing brilliance bias in AI to ensure a more realistic representation of intellectual …
