Interaction Of The Gram-Positive Human Pathogen Staphylococcus Aureus With Host Lipids, Sharanya Paul

Theses and Dissertations

Staphylococcus aureus is a prominent pathogen that is known to incorporate straight-chain unsaturated fatty acids (SCUFAs) into its lipids in addition to the normally biosynthesized branched-chain fatty acids (BCFAs) and straight-chain fatty acids (SCFAs). Furthermore, it has recently been shown that the incorporation of oleic acid into S. aureus lipids significantly enhanced the growth of the organism at low temperatures due to the greater fluidity imparted to the membrane. Together with others in the Wilkinson and Dahl laboratory, I have shown that low-temperature growth is enhanced by various SCUFAs, including the human antimicrobial fatty acids sapienic acid, linoleic acid, and …

The Effect Of Sex On The Signal Transmission Of Duetting Bay Wrens, Rachel C. Schinzler

Theses and Dissertations

During communication, senders send signals for their benefit to elicit a behavioral response from a receiver. Acoustic signals are efficient for long-distance signaling; however, they are influenced by environmental features, such as foliage density, humidity, temperature, and time of day. Individuals can overcome these challenges by using signals with a trajectory of peak frequency, frequencies, volumes, and timing best suited to signal transmission in their environment. Signal transmission has been studied at the species level; however, not much is known about sex differences within the same species. Duetting species provide a useful system for examining sex-specific challenges in transmission, as …

Digital Truth Making, Creative Resistance, And Power Negotiation Through Social Media: A Digital Ethnography Of The 2024 Gen Z Uprising In Bangladesh, Mustafizurrrahman Rahat

Theses and Dissertations

This research investigates how social media shaped political participation during the 2024 July Uprising in Bangladesh, focusing on the production and negotiation of political truth, legitimacy, and resistance through everyday digital practices. Rather than conceptualizing social media solely as a communication tool, the study analyzes digital platforms as contested spaces where activists, state-aligned actors, and other participants constructed, circulated, and challenged competing political narratives throughout the uprising.

Drawing on digital ethnography, this study integrates netnographic observation of Facebook groups, pages, hashtags, memes, and protest-related visual content with content analysis, reflexive participant observation, and semi-structured interviews with Generation Z participants. The …

Tooth Ablation And The Jōmon - Yayoi Transition In Japan, Laura R. Erickson

Theses and Dissertations

The Jōmon – Yayoi period transition in Japan is marked by many migrants coming through the Korean Peninsula into Kyushu, sparking changes such as the introduction of wet-rice agriculture to the native hunter-gatherer-fisher Jōmon population and decreases in tooth ablation patterns and percentages. Ritual tooth ablation, or the removal of healthy front teeth, is typically seen as a coming-of-age practice, with the Jōmon having a diverse amount of ablation patterns. In this study, I explored how the rates and variation of tooth ablation changed throughout Japan after the arrival of Yayoi migrants from the continent. After calculating ablation rates per …

Turning 30 In 600 Feet, Tate Lewis-Carroll

Theses and Dissertations

This thesis is a poem; it records fourteen consecutive months of the poet’s life through rigorous, daily typing habits with nonoptimal tools and material: a typewriter and 600 feet of receipt paper. Through the adoption of these conditions, and through the dailiness of the habit, this thesis crips and deploys a poetics of chronic impediment for accessing constraint and its role in making. This thesis includes a critical preface which explores some of the poet’s specific relationships to chronic pain, both physical and emotional; forgetfulness and dissociation; and disruption by remembering a decade-long flare of chronic illness and abuse. With …

Children’S And Adult Perspectives On Mental Health In Children’S Youth Literature And Media, Edcel J. Cintron-Gonzalez

Theses and Dissertations

My dissertation extends existing work on mental health in children’s literature to examine the different narratives strategies that text, film, and media for young audiences use to connect childhood, caregiving, and emotional wellbeing. Three areas of scholarship—children’s literature scholarship, health humanities work, and feminist care ethics—inform my project. Overall, I am interested in how a variety of genres for young readers represent mental health not only as an individual experience, but also as something shaped by family, culture, community, and adult-child relationships. It is therefore important to delineate the different concepts and frameworks that help make sense of how mental …
