Faculty Research, Scholarly, and Creative Activity

Innovative aircraft design and emerging technologies are enabling new types of uncrewed, high-altitude long endurance (HALE) vehicles, including fixed-wing HALE vehicles and stratospheric balloons to operate above 60,000 feet. However, due to a variety of factors including the diverse performance characteristics and extended mission duration of these new vehicles, the Air Traffic Management system faces challenges in meeting the needs of this high-altitude environment. To address these challenges, the Higher Airspace (HA)/Upper Class E Traffic Management (ETM) concept proposes using a scalable, cooperative approach tailored for high-altitude operations. To evaluate the feasibility of the HA/ETM concept, NASA Ames Research Center …

Psychological Flexibility As A Mechanism Of Change In Online Act Among Adults Living With Chronic Health Conditions, Francesca M. Knudsen, Marissa L. Donahue, Korena S. Klimczak, Ty B. Aller, Michael E. Levin

Psychology Faculty Publications

Living with a chronic health condition (CHC) can negatively impact quality of life (QoL) through a complex interaction of mental health challenges, functional limitations, and disease management demands. Acceptance and Commitment Therapy (ACT) is a transdiagnostic approach that shows promise in addressing shared challenges across various CHCs by fostering psychological flexibility (PF). PF has been associated with improved QoL and functional outcomes and reduced psychological symptoms in individuals living with specific CHCs; yet its mediating role in these outcomes remains underexplored. This secondary analysis examined whether changes in PF mediated improvements in QoL, psychological symptoms, and functional impairment among individuals …

Identification Of Functional Non-Coding Variants Associated With Orofacial Cleft, Priyanka Kumari, Ryan Z Friedman, Michael A White, Barak A Cohen, Et Al.

2020-Current year OA Pubs

Oral facial cleft (OFC) comprises cleft lip with or without cleft palate (CL/P) or cleft palate only. Genome wide association studies (GWAS) of isolated OFC have identified common single nucleotide polymorphisms (SNPs) in many genomic loci where the presumed effector gene (for example, IRF6 in the 1q32 locus) is expressed in embryonic oral epithelium. To identify candidates for functional SNPs at eight such loci we conduct a massively parallel reporter assay in a fetal oral epithelial cell line, revealing SNPs with allele-specific effects on enhancer activity. We filter these SNPs against chromatin-mark evidence of enhancers and test a subset in …

Cryo-Em Structures Of A Pentameric Ligand-Gated Ion Channel In Liposomes, Vikram Dalal, Brandon K Tan, Hanrui Xu, Wayland W L Cheng

2020-Current year OA Pubs

Detergents and lipid nanodiscs affect the cryo-EM structures of pentameric ligand-gated ion channels (pLGICs) including ELIC. To determine the structure of a pLGIC in a membrane environment that supports ion channel function, we performed single particle cryo-EM of ELIC in liposomes. ELIC activation and desensitization were confirmed in liposomes with a stopped-flow thallium flux assay. Using WT ELIC and a non-desensitizing mutant (ELIC5), we captured resting, activated, and desensitized structures at high resolution. In the desensitized structure, the ion conduction pore has a constriction at the 9' leucine of the pore-lining M2 helix, indicating that 9' is the desensitization gate …

Correctional Psychology And Training Implications: A Mixed Analysis Of Trainee Knowledge And Application Of Ethical Dilemmas In Corrections, And A Closer Look At The Experience Of Support From Generalist Training, Alyssa A. Hoyt

Electronic Theses and Dissertations Archive

Correctional psychology, a subfield of psychology, has long been comprised of its own distinct purpose, focus, and competencies. Yet correctional psychology remains unrecognized today as a formal American Psychology Association (APA) specialization. Unlike forensic psychology, without an APA specialization, and subsequent structured training standards, scholars have argued that correctional mental health professionals may be ill-prepared to navigate unique ethical dilemmas inherent to the correctional environment. The present mixed analysis study aimed to contribute to this discussion by assessing psychology trainees’ ability to respond to hypothetical ethical dilemmas in a manner consistent with correctional environments, and whether prior correctional experience/ exposure …

The climate crisis has necessitated immediate and extensive research into sustainable, reliable, and cost-effective energy sources. The global energy shift has accelerated the integration of renewables with various industries and energy storage systems to address the challenges posed by the intermittent nature of renewable energy sources. The UK's hydrogen strategy and zero-emission shipping mission demonstrate promising progress, including the development of green hydrogen and green ammonia production and storage. However, renewable-hydrogen or ammonia storage systems present challenges, including determining effective storage capacity and meeting extensive energy requirements. The authors of this study have previously explored the prospects and feasibility of …

Calibration Of Detectors For The Tomographic Ionized-Carbon Mapping Experiment, Tessalie A. Caze-Cortes

Theses

Observations of the intensity of the sky at millimeter (mm) wavelengths require accurate calibrations for the spectrometers to work with radio telescopes. However, calibrating is a complex and lengthy process for sensitive detectors that catch single photons. To improve efficiency in locating defective detectors and optimizing bias current, my research involves taking data from previous lab characterizations and creating an algorithm that analyzes and plots the code of all 1920 detectors. This thesis will discuss the importance of mm-wavelength intensity mapping and the questions the TIME research team aims to address. Also, a detailed description of mechanical and computational components …

'There Is That Of God In All Of Us': Church, State, And Restrictive Abortion Policies, Kimsey J. Stewart

LSU Master's Theses

Unsafe abortion affects millions of women around the globe every year. Unsafe abortions are more likely to occur in countries with restrictive abortion policies. Yet, these policies persist, and the worldwide trend of liberalization of abortion laws is at risk of reversal. There is a disconcerting lack of research regarding what factors cause governments to enact, retain, and enforce restrictive abortion policies. This paper is an attempt to fill in such a gap. I theorize that countries in which the government has closer ties with religious organizations will have more restrictive abortion policies. My results indicate that this is likely …

Maternal Hyperleptinemia Alters Placental Transcriptome And Progesterone Regulation Without Affecting Early Equine Fetal Growth, Lucinda L. Thorburn

LSU Master's Theses

While consequences of equine obesity are well defined, the extent to which persistent hyperleptinemia and accompanying leptin (Lep) resistance affect the fetal-maternal environment warrants further exploration. This study compared endocrine, fetal, placental, and uterine parameters during early pregnancy (through day 70) in mares with elevated leptin versus normal leptin (NL) concentrations. Fourteen mares were classified as either NL (n = 6; Lep 0.9 ± 0.3 ng/mL), moderate leptin (ML; n = 4; Lep 3.0 ± 0.3 ng/mL), or high leptin (HL; n = 4; Lep 5.8 ± 0.7 ng/mL) based on annual plasma leptin. Mares were artificially inseminated and induced …

Dose Characterization Of Galactic Cosmic Rays In The Human Brain: A Phits-Based Study With A Segmented Anatomical Phantom, Shanice N. Manning

LSU Master's Theses

Astronauts aboard the International Space Station (ISS) are chronically exposed to a complex space radiation environment composed of galactic cosmic rays (GCR), solar particles, and Earth's trapped radiation. These high-energy particles interact with spacecraft shielding, producing secondary particles that can penetrate inside and deposit energy in sensitive tissues. Although animal studies have been useful in assessing space radiation risks, anatomical and physiological differences limit their applicability to human anatomy especially neuroanatomy. To address this gap, we developed a computational framework to model radiation dose distribution within the human brain using Monte Carlo simulations in Particle and Heavy Ion Transport code …

Anxiety's Impact On Autism Spectrum Disorder Symtomology: An Investigation Into The Relationship Between Two Comorbities, Michaela Brown

LSU Doctoral Dissertations

Autism spectrum disorder (ASD) has been found to be frequently comorbid with many medical and psychological disorders, one of which is anxiety disorders. Research has shown that, when anxiety is present within ASD, various areas of the child’s functioning may be impacted, such as ASD symptom severity, emotional regulation skills, adaptability, social skills and daily living skills. The current study aimed to investigate this relationship of anxiety and ASD. First, within a sample of children and adolescents with ASD, the magnitude of the correlation between specific ASD symptoms parent-reported anxiety was compared to determine if certain ASD symptoms were more …

For Us, By Us: A Digital Ethnographic Exploration Of Black Podcasts, Intimacy, & Sexual Pleasure, Dominique C. Dillard

LSU Doctoral Dissertations

Sociological literature written about Black folks interprets their sexual behavior as unhealthy, risky, and non-normative. Black people are seldom acknowledged as humans, so it is not surprising to discover a discourse that does not portray them as sexual subjects. Studies examining Black sexual subjectivity through white and colorblind ideologies dominate the discussion, reproducing racist discourse historically ascribed to Black bodies. Guided by Audre Lorde’s concept of erotic as power, I document an alternative epistemology about Black sexuality. I argue the construction of Black sexuality must focus on sexual selfhood to grasp how this population conceptualizes and makes sense of their …

A Comparative Case Study Of Mentoring Practices By National Board Certified And Non-Certified Teacher Mentors, Bethany Mcclure

LSU Doctoral Dissertations

As preservice teacher candidates engage in field experiences that shape their development of teacher identity, it is important to examine their perceptions of the mentoring process. This study explored how preservice teacher candidates construct their own knowledge about mentoring as a process, as well as explored the perceptions of mentor teachers, both National Board Certified, and non-National Board Certified, as they facilitated the learning and growth of their mentees. Many prior studies on the mentoring process exist, however, a gap in the literature that was identified and explored through this study included the impact that National Board Certified Teachers have …

Digital Forensics And Ai: Artifact Analysis And Using Ai In The Forensics Domain, Clinton Joel Walker

LSU Doctoral Dissertations

Digital Forensics (DF) is a field of forensic science focusing on the acquisition, authentication, and analysis of digital evidence while maintaining integrity of that data. DF analysts use forensic tools to parse large volumes of data for investigations and depend on them for identification of pertinent digital evidence in vast amounts of data. Keeping up with innovations and ever-expanding data volumes is a constant challenge for these investigators. The prevalence of Artificial Intelligence (AI) in everyday computing is rapidly expanding, with the use of Machine Learning (ML) and Large Language Models (LLM)s becoming increasingly commonplace. Innovations in technology bring new …

Towards Leveraging Social Media Data For Fostering Collaborations Among Non-Profits, Monazil Chowdhury

LSU Doctoral Dissertations

Nonprofit organizations serve a crucial role in tackling a wide range of significant social, environmental, and economic issues. But it is often hard to get a clear picture of their work because their information is spread out and it is difficult to see how they are collaborating. To address this issue we developed a web-based tool to collect scattered data—from a variety of sources, such as the IRS, social media, and the Census, into one easy-to-use resource. The tool begins by taking IRS records and geocoding each nonprofit’s physical address With its coordinates. It then retrieves census tract information from …

Human Genetics Publications

Background: The macro-social and environmental conditions in which people live, such as the level of a country’s development or inequality, are associated with brain-related disorders. However, the relationship between these systemic environmental factors and the brain remains unclear. We here aimed to determine the association between the level of development and inequality of a country and the brain structure of healthy adults.

Methods: We conducted a cross-sectional study pooling brain imaging (T1-based) data from 145 magnetic resonance imaging (MRI) studies in 7,962 healthy adults (4,110 women) in 29 different countries. We used a meta-regression approach to relate the brain structure …

Examination Of The Criterion-Related Validity Of The Scales For Assessing Emotional Disturbance – 3rd Edition, Corey Pierce, Jacqueline Huscroft-D'Angelo, Jessica Wery, Brad Uhing, Jodie Martin, Kara Loftin

Journal of Educational Research and Innovation

In this study, we sought to determine if the Scales for Assessing Emotional Disturbance – Third Edition (SAED-3; Epstein et al., 2020) demonstrated adequate validity using criterion validation techniques. The associations between the SAED-3 subscales and composite scores were examined in relation to similar scores from the Behavior Assessment System for Children – Second Edition (BASC-2; Reynolds & Kamphaus, 2004) and the Strengths and Difficulties Questionnaire (SDQ; Goodman, R., 1997). SAED-3 ratings were conducted with either the BASC-2 or SDQ with 121 students ages 6 to 17 years. The overall criterion prediction evidence of …

Intercultural Communication

Communication Research Trends

For the survival and development of important human values, the study of intercultural communication may be one of the critical areas of communication research. One has only to witness "Kojak" and "Starsky and Hutch" bouncing off satellites into the intimacy of minds and homes in cultures of India and Thailand to realize this. Vendors of communication technology are rushing to pen a Pandora's box of influences which may erode cultural ideals created over thousands of years. Once again we are not prepared to cope with the human and social implications of communication technology.

But the focus of research in intercultural …

Religious Communication In An Urban Society

Communication Research Trends

Whatever happened to the churches? To whom are they speaking these day?

Christianity and other major religious traditions developed their symbolic language and their patterns of communication in a pre-industrial world and in the largely oral culture of rural villages. Christianity did adapt rather remarkably to the possibilities of the print media. But now the urban pattern of life, the technical-scientific mode of thought and the electronic media are· influencing radically the pattern of human life.

Sociologists of religion conclude that religious aspirations are as strong as ever, but that people increasingly do not find the expression of their religion …

The Use Of The Media For Formal And Non-Formal Education

Communication Research Trends

Dear Reader,

With some risk of exaggeration, it is said that the media are a major factor in the contemporary social construction of reality, If something isn't in print, radio, TV or other media, it does not "exist" socially and culturally. To the extent that this is true, with the medium of this CSCC NEWSLETTER for our friends and associates as well as colleagues in the field of communication, the CENTER FOR THE STUDY OF COMMUNICATION AND CULTURE begins to exist.

In this first issue it seems appropriate to state why we exist -- our orientation, objectives, and functions. We …

Aeroponic System Optimization For Butterhead Lettuce Growth And Future Sustainability Using Flow Blurring Atomization: An Overview, Taylor J. Johnson

Beyond: Undergraduate Research Journal

The global population has grown by 6 billion people over the last century and is trending toward 9.7 billion people by the year 2050. Agriculture accounts for 70% of global fresh water usage. Technology must be developed to accommodate the increase of food production demanded by the growing global population and the subsequent increase in water usage. Aeroponic technology is a water-efficient vertical farming technology that can reduce water usage by 90% by suspending plant roots in air within a controlled chamber and supplying atomized droplets of a water-nutrient solution directly to the roots.

This study simultaneously tests six droplet …

Qualitative Tools To Enhance Data Analysis From Diverse Sources Of International Education Policy In Order To Create A More Perfect Evaluation Toolset, Robert J. Schulenburg

Capstone Collection

Abstract

This project proposes a new protocol for implementing meta-synthesis as a research tool. Meta-synthesis allows researchers to combine data sets from multiple sources that appear unconnected; it allows data sets to be extracted from multiple domains and knowledge banks that present as being unable to be combined or cross-transferable. This project presents a protocol designed to guide meta-synthesis which was used to extract critical relevant data from the Sustainable Development Goals (SDGs) related to inclusive education and inclusive work and rehabilitation policies and practices. The project shows with deliverables how, with this data in hand, newly aggregated extracted data …
