Dragon Guitars And Sexy Zombies: Tracing The Meta-Motion Of The Naga Motif In Northeast Thailand, Aaron Michael Stanley

Dartmouth College Master’s Theses

Abstract

This thesis traces the evolving symbolism of the Naga motif (a mythic water serpent) in Northeast Thailand through a framework I call meta-motion, which maps symbolic persistence of this cultural signifier and boundary marker across four cultural horizons—animist (Z), Hindu–Khmer (B), Buddhist (A), and modern/global (C). Like electrons in quantum super position, symbolic motifs circulate as overlapping “waves” of potential meaning and are concretized into cultural “particles” only when recruited for specific ritual, commercial, or political purposes. I add a bookend extension to Chang’s Hindu-Buddhist (B/A) typology with the addition of Horizons Z and C in order to make …

Statistical Analysis Of Multi-Endpoint Phenotypic Screening Increases Sensitivity Of Planarian Neurotoxicity Testing, Danielle Ireland, L. J. Word, Eva-Maria S. Collins

Biology Faculty Works

There is an urgent need for high-throughput screening (HTS) models to replace, refine, and/or reduce (“3Rs”) vertebrate toxicity testing. Replacing in vivo animal studies is challenging for neurotoxicity and developmental neurotoxicity (DNT), where the functional relevancy of adverse outcomes needs to be assessed on the whole organism. We previously screened the NTP 87-compound library (NTP87), consisting of known and suspected developmental neurotoxicants, and showed that planarian HTS can identify known (developmental) neurotoxicants. Because analysis methods can impact screening results, and our original analysis used the lowest-observed-effect-level (LOEL) only, we hypothesized that the use of state-of-the-art statistical analysis would increase the …

Tort Liability For Failure To Age Gate: A Promising Regulatory Response To Digital Public Health Hazards, Matthew B. Lawrence, Brett Frischmann, Avi Sholkoff

Faculty Publications

Tort liability for failure to “age gate” is a promising legal response to the public health hazards of AI, social media, sports gambling, and other digital spaces. Tort liability for failure to “age gate” hinges liability for harms to minors on an app’s failure to take reasonable steps to prevent minors from gaining access or otherwise to apply appropriate governance rules, such as privacy-protective default settings or ensuring genuine parental consent. While no one legal response is a panacea, tort liability for failure to age gate carries several distinctive advantages that make it a particularly promising option at this stage …

Real-Time Feedback On User-Written Generative Artificial Intelligence Model Prompts, Gulmohar Khan, Ramprasad Sedouram, Karthik Srinivas

Defensive Publications Series

A common user interface for consumer use of generative artificial intelligence (genAI) tools is a chat interface, where a user can input their request as a text prompt within an input field and where the genAI model generates a response that answers the prompt. When users are insufficiently skilled at prompting, they may require multiple interactions with the genAI tool before a satisfactory result is generated. There are no mechanisms that guide the users to provide a prompt that uses good prompting strategies to express their intent. Also, user-provided prompts may include errors, gaps, or other issues that impact the …

Although employing deep learning methods might increase time consumption and computational complexity, an edge computing system enables devices to transfer their demanding jobs to edge servers, decreasing …

Unheard And Underserved: The Role Of Narratives And Shared Experiences Of Systemic Racism In The Black Community’S Engagement With Mental Health Services, Essence Jones

Master of Arts in Human Services

This research examines the intersection of systemic racism and mental healthcare in the Black community, focusing on the reluctance to engage with mainstream services. Grounded in historical analysis, the study traces how slavery, segregation, and discriminatory policies have shaped enduring mistrust toward mental health systems. Despite progress in health equity initiatives, cultural insensitivity, underrepresentation of Black providers, and ongoing structural barriers persist. Drawing from peer-reviewed literature, the work explores narratives and collective memories that influence perceptions of care, including the role of faith-based coping, stigma, and alternative healing practices. Special attention is given to the compounded effects of intersectional identities …

A Complex Border: Intractability And The Physical Roots Of Discursive Legitimations In Cyprus, Hilmi Ulas

Peace Studies Faculty Articles and Research

The Cypriot conflict is one of the most intractable conflicts of the modern era, and the collapse of complexity among the actors in the conflict—mainly the Republic of Cyprus, North Cyprus, and Turkey—appears to be the main cause of the continued “no war, no peace” state. Subsequent socio-psychological self-organization among these actors then produces conflict-perpetuating feedback loops and dynamics. These dynamics include identity narratives, narratives of “the other,” and narratives of the nature of the conflict, which, at the grassroots level, can legitimize ongoing engagement in the conflict, whereas peace is painted as an undesirable and undeserved/unjust compromise. Given this, …

Neurophysiology And Behavior Lab, University Of Mississippi

University Website Migration from WordPress

The Neurophysiology and Behavior Laboratory investigates the neurobiological mechanisms of behavior. A major goal in neuroscience is to understand how the brain processes salient environmental stimuli and promotes behavioral adaptation. Under some circumstances (i.e. stress) changes in neuronal activity generate mal-adaptive behavior and ultimately the development of psychiatric disorders such as drug addiction. Our challenge is to identify how and when neuronal changes are translated into pathological behavior. The Neurophysiology and Behavior Lab is located in the Thad Cochran Research Center on campus (animal facility). We utilize in vivo electrophysiology and pharmacology to track the neuronal correlates of behavior.

Dynamic Remodeling Of Centrioles And The Microtubule Cytoskeleton In The Lifecycle Of Chytrid Fungi, Alexandra F Long, Krishnakumar Vasudevan, Andrew Swafford, Claire M Venard, Jason E Stajich, Lillian K Fritz-Laylin, Jessica L Feldman, Tim Stearns

Biology Faculty Publications

Cell movement and division are complex behaviors driven by a dynamic internal cytoskeleton. The molecular components and principles of cytoskeletal assembly are well studied, but less is known about cytoskeletal remodeling events, including how centrioles transition from ciliary base to centrosome. Here we address this using the chytrid Rhizoclosmatium globosum, a zoosporic fungus which has centrioles and cilia, lost in most fungal lineages. Chytrids undergo reorganization of their microtubule cytoskeleton as they grow from zoospore to multinucleated coenocyte. We use evolutionary comparison, RNA sequencing, and expansion microscopy to understand this reorganization and further develop this organism as a model for …

Current Mechanobiological Pathways And Therapies Driving Spinal Health, Rahul Kumar, Kyle Sporn, Harlene Kaur, Akshay Khanna, Phani Paladugu, Nasif Zaman, Alireza Tavakkoli

SKMC Student Presentations and Publications

Spinal health depends on the dynamic interplay between mechanical forces, biochemical signaling, and cellular behavior. This review explores how key molecular pathways, including integrin, yeas-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ), Piezo, and Wingless/Integrated (Wnt) with β-catenin, actively shape the structural and functional integrity of spinal tissues. These signaling mechanisms respond to physical cues and interact with inflammatory mediators such as interleukin-1 beta (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α), driving changes that lead to disc degeneration, vertebral fractures, spinal cord injury, and ligament failure. New research is emerging that shows scaffold designs that can …

Dominant Mid-To-High-Frequency Harmonics Predict Neural Encoding And Perception Of Concurrent Vowels With Large F0 Differences, Fan-Yin Cheng, Sarah Medina, Olaedochim Obinna, Spencer Smith

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Concurrent vowel perception experiments have revealed the importance of fundamental frequency (f₀) differences in speech stream segregation. Understanding neural processes that support speech streaming using f₀ differences remains an active area of perceptual and neurocomputational modeling research. This study simultaneously measured subcortical neural encoding [frequency following responses (FFRs)] and cued vowel identification accuracy of 12 concurrent vowel mixtures with large f₀ differences (>8 semitones) to assess whether f₀-based neural channel selection predicted perception. Results indicated that the strength of f₀-based neural channel selection for one vowel often depended on the …

Tmco1 As An Endoplasmic Reticulum Calcium Load-Activated Channel: Mechanisms And Disease Implications, Jingbo Wang, Panpan Zhu, Zhuohang Li, Xiaohui Su, Mingzhu Qi, Aimin Zhou, Xiangying Kong

Chemistry Faculty Publications

Calcium ions (Ca2+) play a vital role in many biological processes. Transmembrane and coiled-coil domain 1 (TMCO1) has been characterized as an endoplasmic reticulum (ER) transmembrane protein in recent years. It keeps the cytoplasm and ER's Ca2+ homeostasis stable by acting as a novel calcium channel. Studies from different laboratories have revealed that the mutation or deficiency of TMCO1 is closely correlated with several diseases, including cerebro-facio-thoracic dysplasia (CFTD), glaucoma, premature ovarian failure (POF), osteoporosis, and cancer. Here, we review the characteristics of TMCO1 and its involvement in related diseases, which may provide useful information for developing therapeutic strategies for …

Ecological Drivers And Temporal Dynamics Of Daphnia In A Diverse Environmental And Spatial Landscape, Crysta A. Gantz

Dissertations and Theses

In the modern era, commonly referred to as the Anthropocene, human-caused changes to the environment are prevalent and complex. The study of impacts to biodiversity and ecosystem functioning requires multi-faceted approaches that encompass scales of organization from genes to ecosystems. It is often difficult to tease apart whether species responses to environmental change are due to phenotypic plasticity or genotypic variation. Therefore, it is important to try to understand where variation originated, that is, to link a phenotypic response to a genetic change or to gauge whether the response is from the environment. In addition, neutral genetic variation arising from …

The Promise And Peril Of Comparing Fluorescence Lifetime In Biology Revealed By Simulations, Pingchuan Ma, Peter Chen, Scott Sternson, Yao Chen

2020-Current year OA Pubs

Signaling dynamics are crucial in biological systems, and biosensor-based real-time imaging has revolutionized their analysis. Fluorescence lifetime imaging microscopy (FLIM) excels over the widely used fluorescence intensity imaging by allowing the measurement of absolute signal levels independent of sensor concentration. This capability enables the comparison of signaling dynamics across different animals, body regions, and timeframes. However, FLIM's advantage can be compromised by factors like autofluorescence in biological experiments. To address this, we introduce FLiSimBA, a flexible computational framework for realistic
