School of Medicine Publications

Advances in genetics and developmental biology are revealing the relationship between genotype and dental phenotype (G:P), providing new approaches for how paleontologists assess dental variation in the fossil record. Our aim was to understand how the method of trait definition influences the ability to reconstruct phylogenetic relationships and evolutionary history in the Cercopithecidae, the Linnaean Family of monkeys currently living in Africa and Asia. We compared the two-dimensional assessment of molar size (calculated as the mesiodistal length of the crown multiplied by the buccolingual breadth) to a trait that reflects developmental influences on molar development (the inhibitory cascade, IC) and …

Planttracker: An R Package To Translate Maps Of Plant Occurrence Into Demographic Data, Alice E. Stears, Peter B. Adler, Shannon E. Albeke, David H. Atkins, Jared Studyvin, Daniel C. Laughlin

Wildland Resources Faculty Publications

1. Long-term demographic data are rare yet invaluable for conservation, management, and basic research on the underlying mechanisms of population and community dynamics. Historical and contemporary mapped datasets of plant location and basal area present a relatively untapped source of demographic records that, in some cases, span over 20 years of sequential data collection. However, these maps do not uniquely mark individual plants, making the process of collecting growth, survival, and recruitment data difficult.
2. Recent efforts to translate historical maps of plant occurrence into shapefiles make it possible to use computer algorithms to track individuals through time and determine individual growth …

The Effects Of Digital Game-Based Instruction On Knowledge Acquisition And Retention Of Genetics Content, Brinley Kantorski

Electronic Theses and Dissertations

Digital educational games have been a part of the educational landscape since the early 1970s. Since then, there has been a proliferation in the quantity, format, type, and quality of digital educational games available to classroom teachers. Despite this, the body of literature surrounding the effectiveness of these digital educational games remains highly fragmented and lacks unifying themes. While some literature exists to support the use of digital educational games in immediate knowledge acquisition, little research has been done on how digital educational games impact the retention of knowledge in the long term. As such, this study examines how the …

Identification And Characterization Of Genetic Elements That Regulate A C-Di-Gmp Mediated Multicellular Trait In Pseudomonas Fluorescens, Collin Kessler

Electronic Theses and Dissertations

Microbial communities contain densely packed cells where competition for space and resources are fierce. These communities are generally referred to as biofilms and provide advantages to individual cells against immunological and antimicrobial intervention, dehydration, and predation. High intracellular pools of cyclic diguanylate monophosphate (c-di-GMP) cause cells to aggregate during biofilm formation through the production of diverse extracellular polymers. Genes that encode c-di-GMP catalytic enzymes are commonly mutated during chronic infections where opportunists display enhanced resistance to phagocytosis and antibiotics. Our lab uses an emergent multicellular trait in the model organism Pseudomonas fluorescens Pf0-1 to study the emergence of c-di-GMP mutations …

Promoting Trauma-Informed Competencies In Public School Teachers And Staff, Stephanie Stern

Electronic Theses and Dissertations

Childhood trauma is prevalent among today’s students. When educators implement trauma-informed practices in schools, student behaviors and learning typically improve. It is thus important that educators are trained in and have positive attitudes, knowledge, and beliefs toward trauma-informed care. However, high proportions of educators report that they do not receive trauma-informed training, and research regarding the effectiveness of professional development in trauma-informed care is limited. The present study examined whether educators’ knowledge, attitudes, and beliefs regarding trauma-informed care differed by grade level of students worked with and previous professional development experiences in trauma-informed care, as well as tested the effectiveness …

Electronic Theses and Dissertations

Dissertation supervised by Dr. Debra Hyatt-Burkhart

This study sought to unearth the lived experience of counselors empathically responding to clients via telephonic counseling during COVID-19. The term empathic response refers to as attending to the emotional and mental state of another person in a way that is attuned with the feelings and meanings of the individual’s experience. There are few studies that have assessed the merits of telephonic counseling, and even fewer that have examined counselors’ empathic response to clients through this medium.

To uncover the lived experience of the target population, the participants of the study were purposefully selected …

Theory Of Aqueous Solvation: Uninterrupted, Cyclic Hydrogen-Bonding Essential For Accurate Keto-Enol Energies And Grotthuss Tautomerism Of Acetone, Mark Recznik

Electronic Theses and Dissertations

Keto-enol tautomerization (KET) is a fundamental process impacting a range of molecular phenomena in organic and biochemistry. However, the accurate computation of solution-phase KET energies remains a challenge, even for prototypical acetone.

In Part I, keto-enol tautomers of acetone were incorporated into solvent clusters that interact via uninterrupted, cyclic hydrogen-bonding (UCHB) networks. An empirical model was created to predict accurate KET energies, E_taut, of simple carbonyl compounds. Based on the availability of experimental data and structural simplicity, acetone was selected as a prototype. A discrete-continuum strategy was employed – accounting simultaneously for local noncovalent interactions and bulk-phase effects …

Quality By Design Based Optimization Of Anti-Inflammatory Nanoemulgels For Local Treatment Of Burn Wounds, Leah Dickey

Electronic Theses and Dissertations

Burns are some of the most traumatizing and damaging skin injuries, with the potential of causing extensive internal damage that increases the risk of chronic wound development. Oral and topical analgesics in combination with antibiotics can provide temporary relief and improve wound healing progress for both mild and severe burns. However, recurrent systemic exposure to pain relievers and antibiotics has been associated with adverse side effects including nausea, drowsiness, abdominal pain, etc., and increased risk of new infections or even ulcers. Local and targeted drug delivery systems, such as nanomedicine, have gained attention as potentially more effective alternatives to improve …

Calm-Mo: An Integrative Tool For Psychological Mindfulness, Charles L. Miller

Dissertations, 2020-current

Henriques has developed a “Unified Theory” that consists of eight key ideas he argues can effectively frame both the science of psychology and the practice of psychotherapy. CALM-MO, the eighth of these ideas, offers an integrative, principled approach to psychological mindfulness. CALM-MO is an acronym that encapsulates the process of cultivating a “calm” meta-cognitive observer that embodies the attitudes of curiosity, acceptance, loving compassion, and motivation toward valued states of being. Henriques posits that the idea consolidates key elements from across the various schools of thought to bring together essential therapeutic principles geared toward seeking and maintaining well-being. As such, …

Mauter, Nicolas Bambach, Andrew J. Mcelrone, Joseph G. Alfieri, Lawrence E. Hipps, John H. Prueger, Sebastian J. Castro, Maria Mar Alsina, William P. Kustas, Forrest S. Melton

AES Faculty Publications and Presentations

Characterization of model errors is important when applying satellite-driven evapotranspiration (ET) models to water resource management problems. This study examines how uncertainty in meteorological forcing data and land surface modeling propagate through to errors in final ET data calculated using the Satellite Irrigation Management Support (SIMS) model, a computationally efficient ET model driven with satellite surface reflectance values. The model is applied to three instrumented winegrape vineyards over the 2017-2020 time period and the spatial and temporal variation in errors are analyzed. We illustrate how meteorological data inputs can introduce biases that vary in space and at seasonal timescales, but …

Weathering The Storm: Navigating Urban Ecologies Of Communication In Times Of Crisis, Austin Hestdalen

Electronic Theses and Dissertations

This project explores cities as urban ecologies of communication in which crises emerge and are given significance within the dialogic relations cultivated among public actors attempting to make a living, together, within the shared historical-cultural contexts of everyday life. To describe cities as urban ecologies of communication is to describe them in terms of urban communication and its interdisciplinary foundations in the study of rhetoric, philosophy, planning, policy, architecture, sociology, geography, and media. The first chapter introduces the challenges of urban risk and crisis management within the complex ecologies of communication constituted by cities and reviews how ‘risk’ and ‘crisis’ …

Without Permanence: Mapping Multi-Genre, Cross-Disciplinary Frameworks For Trans* Studies, Jesse Jack

Electronic Theses and Dissertations

This project takes a cross-disciplinary and multi-genre approach to Transgender (Trans*) Studies to proliferate diverse and ambiguously-gendered representations of trans* experiences across time. It identifies the emergence of rhetorical intertextuality in recent trans* literatures as a discursive response to the biopolitical regulation and erasure of ambiguously-gendered, trans* experiences. It identifies the intersecting influences of twentieth- and twenty-first-century medical paradigms, surveillance apparatuses, popular trans* autobiographies, and archives in representing and exceptionalizing certain trans* experiences over others. In contrast, this project engages in a close reading of Pajtim Statovci’s Crossing (2016) and Andrea Lawlor’s Paul Takes the Form of a Mortal Girl …

Experience Is The Best Teacher: Exploring Clinical Supervisors’ Experiences Who Receive Exclusively Administrative Supervision From Non-Licensed/Non-Clinically Trained Superiors, Monica Pattillo

Electronic Theses and Dissertations

The goals of clinical supervision are to ensure that the supervisee is using skills appropriately and properly handling a client caseload, all while being mentored by an experienced professional, known as a clinical supervisor. However, little is known about the support clinical supervisors receive in their roles. If the support is inadequate, there is a potential to impact the welfare of the clients. Additionally, there are very few researchers that have looked at clinical supervisors’ experiences when receiving their own supervision. In order to add to the body of literature on clinical supervision, this study explored clinical supervisors’ experiences when …

Immunotherapy For Type 1 Diabetes Mellitus By Adjuvant-Free Schistosoma Japonicum-Egg Tip-Loaded Asymmetric Microneedle Patch (Stamp), Rengui Xu, Yusheng Gong, Zhengming Fang, Ting Wang, Wei Chen

Faculty, Staff and Student Publications

BACKGROUND: Type 1 diabetes mellitus (T1DM) is an autoimmune disease mediated by autoreactive T cells and dominated by Th1 response polarization. Insulin replacement therapy faces great challenges to this autoimmune disease, requiring highly frequent daily administration. Intriguingly, the progression of T1DM has proven to be prevented or attenuated by helminth infection or worm antigens for a relatively long term. However, the inevitable problems of low safety and poor compliance arise from infection with live worms or direct injection of antigens. Microneedles would be a promising candidate for local delivery of intact antigens, thus providing an opportunity for the clinical immunotherapy …

Testing Oxygenated Microbubbles Via Intraperitoneal And Intrathoracic Routes On A Large Pig Model Of Lps-Induced Acute Respiratory Distress Syndrome, Riaz Ur Rehman Mohammed, Nathaniel T. Zollinger, Andrea R. Mccain, Roser Romaguera-Matas, Seth P. Harris, Keely L. Buesing, Mark A. Borden, Benjamin S. Terry

Department of Mechanical and Materials Engineering: Faculty Publications

With a mortality rate of 46% before the onset of COVID-19, acute respiratory distress syndrome (ARDS) affected 200,000 people in the US, causing 75,000 deaths. Mortality rates in COVID-19 ARDS patients are currently at 39%. Extrapulmonary support for ARDS aims to supplement mechanical ventilation by providing life-sustaining oxygen to the patient. A new rapid-onset, human-sized pig ARDS model in a porcine intensive care unit (ICU) was developed. The pigs were nebulized intratracheally with a high dose (4 mg/kg) of the endotoxin lipopolysaccharide (LPS) over a 2 h duration to induce rapid-onset moderate-to- severe ARDS. They were then catheterized to monitor …

Bot-Mgat: A Transfer Learning Model Based On A Multi-View Graph Attention Network To Detect Social Bots, Eiman Alothali, Motamen Salih, Kadhim Hayawi, Hany Alashwal

All Works

Twitter, as a popular social network, has been targeted by different bot attacks. Detecting social bots is a challenging task, due to their evolving capacity to avoid detection. Extensive research efforts have proposed different techniques and approaches to solving this problem. Due to the scarcity of recently updated labeled data, the performance of detection systems degrades when exposed to a new dataset. Therefore, semi-supervised learning (SSL) techniques can improve performance, using both labeled and unlabeled examples. In this paper, we propose a framework based on the multi-view graph attention mechanism using a transfer learning (TL) approach, to predict social bots. …

"I'M Not Your Ride Or Die": A Qualitative Study Of Black Women's Experiences In Intimate Marketplaces, Alana Jamelle Peck

LSU Doctoral Dissertations

Black women’s marriage rates have consistently been on the decline since the 1960’s and currently, Black women are the least likely to get married across all races and genders (Bureau 2020). Scholars have been using these statistics to tell monolithic narratives of Black womanhood, and even blame Black women for larger issues within the Black community (Collins 2000, Johnson and Loscocco 2015; Moynihan 1965). Prior scholars have also attempted to provide solutions to this problem, while never even approaching Black women, to suggest ways that they can increase their marriage rates and consequently uplift Black families and the Black community …

Targeting Hyaluronic Acid Synthase-3 (Has3) For The Treatment Of Advanced Renal Cell Carcinoma, Tatsunori Miyata, Chunhua Lin, Jinbo Yang

Faculty, Staff and Student Publications

Non-alcohol-associated fatty liver/steatohepatitis (NAFL/NASH) has become the leading cause of liver disease worldwide. NASH, an advanced form of NAFL, can be progressive and more susceptible to developing cirrhosis and hepatocellular carcinoma. Currently, lifestyle interventions are the most essential and effective strategies for preventing and controlling NAFL without the development of fibrosis. While there are still limited appropriate drugs specifically to treat NAFL/NASH, growing progress is being seen in elucidating the pathogenesis and identifying therapeutic targets. In this review, we discussed recent developments in etiology and prospective therapeutic targets, as well as pharmacological candidates in pre/clinical trials and patents, with a …

Identification Of Missing Hierarchical Relations In The Vaccine Ontology Using Acquired Term Pairs, Licong Cui

Faculty, Staff and Student Publications

Background

The Vaccine Ontology (VO) is a biomedical ontology that standardizes vaccine annotation. Errors in VO will affect a multitude of applications that it is being used in. Quality assurance of VO is imperative to ensure that it provides accurate domain knowledge to these downstream tasks. Manual review to identify and fix quality issues (such as missing hierarchical is-a relations) is challenging given the complexity of the ontology. Automated approaches are highly desirable to facilitate the quality assurance of VO.

Methods

We developed an automated lexical approach that identifies potentially missing is-a relations in VO. First, we construct two types …

The Bahariya Oasis area is characterized by many Valuable regions that have not been included on the tourism map by the Egyptian government. To achieve those objectives, the researcher adopted the 'Analytic-Descriptive Approach', as it is suitable for this study throughout reviewing the literature related to the research subject, describing the current situation, …

Association Of Abdominal Aortic Calcification With Peripheral Quantitative Computed Tomography Bone Measures In Older Women: The Perth Longitudinal Study Of Ageing Women, Jack Dalla Via, Marc Sim, John T. Schousboe, Douglas P. Kiel, Kun Zhu, Jonathan M. Hodgson, Abadi K. Gebre, Robin M. Daly, Richard L. Prince, Joshua R. Lewis

Research outputs 2022 to 2026

We have previously shown that abdominal aortic calcification (AAC), a marker of advanced atherosclerotic disease, is weakly associated with reduced hip areal bone mineral density (aBMD). To better understand the vascular–bone health relationship, we explored this association with other key determinants of whole-bone strength and fracture risk at peripheral skeletal sites. This study examined associations of AAC with peripheral quantitative computed tomography (pQCT)-assessed total, cortical and trabecular volumetric BMD (vBMD), bone structure and strength of the radius and tibia among 648 community-dwelling older women (mean ± SD age 79.7 ± 2.5 years). We assessed associations between cross-sectional (2003) and longitudinal …
