Dietary supplement use in the United States is widespread and increasing, especially among certain population groups, such as older Americans. The science surrounding dietary supplements has evolved substantially over the last few decades since their formal regulation in 1994. Much has been learned about the mechanisms of action of many dietary supplement ingredients, but the evidence on their health effects is still building. As is true of much nutrition research, there are many studies that point to health effects, but not all are at the level of scientific evidence (e.g., randomized controlled interventions), rigor, or quality needed for definitive statements …

A Friendship Of Two Prima Donnas: The Letters Of Adelina Patti To Giulia Valda, Jacquelyn Ancelet

LSU Master's Theses

Of the many prima donnas of the nineteenth century, Adelina Patti (1843–1919) stands out as one of the most successful, with a fifty-year international concertizing career. Biographers across multiple languages have covered her career in great depth, but devote little attention to her close friendships. Herman Klein (in The Reign of Patti [1920]) and John Cone (in Adelina Patti: Queen of Hearts [1993]), for instance, claim that Patti was known by many, but understood by few. One who does seem to have understood her and developed a close relationship with her was Giulia Valda (1850–1925), herself a professional singer, if …

The Anatomy Of Inequality: Medicine, Mourning, And Socioeconomic Status In Victorian England, Molly G. Decker

LSU Master's Theses

"The Anatomy of Inequality: Medicine, Mourning, and Socioeconomic Status in Victorian England," examines the historic relationships between socioeconomic inequality, death, and medical practice during the Victorian period, with specific ttention on London and surrounding areas. I argue that the extreme socioeconomic disparities of the time were deeply intertwined with the practices surrounding death, mourning, and medical care. The first chapter, "The Price of Sorrow," explores the elaborate mourning rituals and displays of status among the wealthy and upper to middle-class Victorians, detailing how these practices were not only expressions of grief but also conspicuous displays of social status and wealth. …

Elementary Science Teachers' Experiences: A Case Study On The Use Of Science+Cyber Curriculum, Laurie Salvail

LSU Doctoral Dissertations

The field of science education in the United States has undergone a major reform since 2015. A little more than twelve years ago, work began on constructing a framework for elementary, middle, and high school science education. This framework emphasized the shift from science being merely a memorization of facts to experiences that include science and engineering practices applied through crosscutting concepts and focused on core ideas in the field of science. With new standards teachers also have to overcome a) not having adequate time available to devote to science instruction b) lack of updated instructional materials aligned to the …

Development And Operationalizing Of The Learning Experience Design Process To Create Integrated Stem Interventions, Vanessa Begat

LSU Doctoral Dissertations

Globally, the demand for people prepared to enter Science, Technology, Engineering and Math (STEM) careers is increasing. To help fill this demand, many formal and informal STEM educational interventions have been implemented in the K-12 domain. However, due to the lack of a clearly defined framework for documenting the nature and scope of the intervention (National Research Council, 2014), the interventions vary greatly in their success, sustainability, and replicability. This research is grounded in Educational Design Research and uses the principle of Learning Experience Design (LXD) to develop a framework for thoughtfully designing and documenting a STEM intervention. This framework …

Canine Hepatocellular Carcinoma: Evaluating Pgam5 And Heterobilharzia Americana, Priscilla Devora

LSU Doctoral Dissertations

Hepatocellular carcinoma (HCC) is the most common primary liver cancer in humans and domestic dogs. Despite extensive research, the mechanisms that drive HCC carcinogenesis and perpetuate cancer survival are incompletely understood in both species. The work described herein focused on finding similarities between canine and human HCC, which could be harnessed to benefit humans and dogs with cancer. The first aim was to investigate the expression of phosphoglycerate mutase 5 (PGAM5) in canine HCC. Upregulation of PGAM5 is a negative prognostic indicator in human HCC. Using archival formalin-fixed paraffin-embedded samples, we found that PGAM5 was overexpressed in canine HCC ( …

Optimizing Associative Memory In Autistic And Non-Autistic Adults: Retrieval Practice, Post-Retrieval Feedback, And Gesture, Brianna E. Cairney

LSU Doctoral Dissertations

Associative memory—or the ability to form a memory representation linking two previously unrelated concepts—is a critical aspect of learning. This work provides insight into strategies that can be used to support associative memory, their underlying mechanisms, and their effectiveness in autistic and non-autistic learners. Chapter 1 demonstrates that iconic gestures can be used as a tool to enhance associative memory by increasing word concreteness and imageability. This effect was eliminated when the iconic gestures were interspersed with ambiguous nonsense gestures, suggesting a boundary on these benefits that depends on listener expectations regarding gesture clarity. However, it remains unknown whether gestures …

Hd-Tdcs Over Left Supplementary Motor Area Differentially Modulated Neural Correlates Of Motor Planning For Speech Vs. Limb Movement, Fatemeh Tabari, Celeste Patron, Hope Cryer, Karim Johari

Faculty Publications

The supplementary motor area (SMA) is implicated in planning, execution, and control of speech production and limb movement. The SMA is among putative generators of pre-movement EEG activity which is thought to be neural markers of motor planning. In neurological conditions such as Parkinson's disease, abnormal pre-movement neural activity within the SMA has been reported during speech production and limb movement. Therefore, this region can be a potential target for non-invasive brain stimulation for both speech and limb movement. The present study took an initial step in examining the application of high-definition transcranial direct current stimulation (HD-tDCS) over the left …

Transcription Decisions Of Conjoined Independent Clauses Are Equitable Across Dialects But Impact Measurement Outcomes, Janna B. Oetting, Tahmineh Maleki

Faculty Publications

Purpose: Transcription of conjoined independent clauses within language samples varies across professionals. Some transcribe these clauses as two separate utterances, whereas others conjoin them within a single utterance. As an inquiry into equitable practice, we examined rates of conjoined independent clauses produced by children and the impact of separating these clauses within utterances on measures of mean length of utterance (MLU) by a child’s English dialect, clinical status, and age. Method: The data were archival and included 246 language samples from children classified by their dialect (African American English or Southern White English) and clinical status (developmental language disorder [DLD] …

Spatiotemporal Analysis Of Nighttime Crimes In Vienna, Austria, Jiyoung Lee, Michael Leitner, Gernot Paulus

Studying the spatiotemporal dynamics of crime is crucial for accurate crime geography research. While studies have examined crime patterns related to weekdays, seasons, and specific events, there is a noticeable gap in research on nighttime crimes. This study focuses on crimes occurring during the nighttime, investigating the temporal definition of nighttime crime and the correlation between nighttime lights and criminal activities. The study concentrates on four types of nighttime crimes, assault, theft, burglary, and robbery, conducting univariate and multivariate analyses. In the univariate analysis, correlations between nighttime crimes and nighttime light (NTL) values detected in satellite images and between streetlight …

A Simple Approach To Dealing With Partial Contestation, Ali Kagalwala, Thiago M.Q. Moreira, Guy D. Whitten

Faculty Publications

Objective: We propose a simple approach to dealing with partial contestation in models of multiparty elections. Methods: Our proposed approach is to add a tiny value to the vote share of parties that do not contest a district and then to include dummy variables identifying those districts in which parties do not compete. We can then estimate a single system of equations using a seemingly unrelated regression (SUR) approach and Aitchison's log-ratio transformation. In our SUR system, we interact the dummy variable for a party that partially contested districts with other predictors in the equation that uses the share of …

Language Discrimination Using Bilingual Picture Exchange For Culturally And Linguistically Diverse Children With Autism Spectrum Disorder, River Waits

LSU Doctoral Dissertations

Recent research suggests that one-fifth of United States households use non-English languages in the home setting. Ethically and effectively supporting culturally and linguistically diverse (CLD) clients (e.g., autistic individuals) presents a growing challenge to practitioners of Applied Behavior Analysis (ABA). Though efforts to address the linguistic needs of the population have grown in recent years, current literature focuses on language selection for monolingual services and underemphasizes the need for bilingual service provision. Studies were conducted to (I) evaluate the efficacy of bilingual picture exchange (i.e., mand response) across items, speakers, and languages (i.e., English and Spanish) as well as (II) …

No Evidence For Metabolic Adaptation During Exercise-Related Energy Compensation, E. W. Flanagan, G. Sanchez-Delgado, C. K. Martin, E. Ravussin, H. Pontzer, L. M. Redman

Clinical Research Faculty Publications

The constrained energy model posits that the increased total daily energy expenditure (TDEE) in response to exercise is often less than the energy cost of the exercise prescribed. The mechanisms behind this phenomenon, coined “exercise-related energy compensation” (ExEC), are poorly understood, and it is unknown if ExEC is coupled with metabolic adaptation. Using a randomized controlled 24-week exercise intervention, individuals who demonstrated ExEC were identified. Changes to all components of TDEE and metabolic adaptation were assessed using doubly labeled water over 14 days and room calorimetry over 24-h 48% of individuals exhibited ExEC (−308 ± 158 kcals/day). There were no …

Consumer Behavior Analysis Approach To Teacher Choice Of Reading Interventions, Rochelle N. Picardo

LSU Doctoral Dissertations

The use of Evidence-based Practices (EBPs) in schools is heavily emphasized in educational research and policy; however, many teachers do not use EBPs for reading instruction and intervention. Previous research on the limited use of EBPs in classrooms has primarily focused on teacher characteristics, such as their attitudes or beliefs toward these practices. As an alternative to this view, this study applied a behavioral economic approach to understanding teacher choice (i.e., EBPs over other alternatives, such as interventions with a base of limited empirical support; low-value practices [LVPs]). Hypothetical Intervention Choice Tasks were developed and used to evaluate how both …

Desire Paths In The Information Landscape, Victoria Van Hyning, Mason A. Jones, Travis Wagner

Journal of Critical Digital Librarianship

Libraries and archives serve so many different users who come to information institutions with various perspectives, needs, experiences, and desires around accessing physical or digital collections. While our users may find what they are looking for immediately, many have to beat their own paths through complex systems and metadata that doesn’t align with their needs. Their search strategies may leave digital “desire paths”–alternative routes through the information landscape that can show us how to better meet their needs. This article covers three scenarios where users’ desire paths can be seen or where gaps around user experience can be better addressed. …

Selection Of Host Plants For Production Of Clanis Bilineata (Lepidoptera: Sphingidae), Xiaofeng Li, Mingming Guo, Kebin Li, Song Li, Honglin Feng, Jiwei Fan

Faculty Publications

Clanis bilineata Walker (Lepidoptera: Sphingidae), a burgeoning edible insect, is experiencing rising demand in China and other regions. Despite this interest, larval production is currently constrained by the limitations of artificial production technologies, particularly the selection of optimal host plants. This study rigorously evaluated the performance of C. bilineatha larvae on four main host plants: round-leaf soybean, pointed-leaf soybean, black locust, and kudzu. Preference tests demonstrated that the larvae were most attracted to black locust (34.76 ± 4.65%), with subsequent preferences for kudzu (25.00 ± 6.12%), round-leaf soybean (23.17 ± 2.79%), and pointed-leaf soybean (14.02 ± 4.74%).

Direct And Indirect Effects Of And Preference For Feedback During The Good Behavior Game In Elementary Classes, Jensen Chotto

LSU Doctoral Dissertations

The Good Behavior Game (GBG) is an effective procedure for reducing disruptive classroom behavior. In this study, students in 3 fifth grade classes selected the rules of the GBG and then experienced the GBG with different forms of feedback delivery for rule violations (vocal and visual, vocal only, visual only, no feedback) on disruptive classroom behavior in a multielement design. All versions of the GBG substantially reduced disruptive behavior below baseline levels. Additionally, in 1 of 3 classes, losing the GBG produced an increase in negative peer interactions immediately following the GBG. Subsequently, students selected which condition they previously experienced …
