The Prime Aesthetic: Exploratory Research On The Relationship Between The Imprinting Of Aesthetic Dress Preferences And The Sensitive Period Of Emerging Adulthood, Jeremy Bernardoni

LSU Doctoral Dissertations

The purpose of this research was to explore the theoretical concept of Prime Aesthetic across generational cohorts through the investigation of individual aesthetic dress preferences (ADP), which are formed during the Prime of Life, and their potential influence on present-day ADP. The Prime Aesthetic concept is defined as a theoretical concept representative of the cumulative ADP imprinted from all influences during an individual’s Prime of Life. The Prime Aesthetic was derived from Holbrook and Schindler’s (1989) study on the development of musical tastes during late adolescence and early adulthood and linked to theories on imprinting during sensitive periods (Bornstein, 1989) …

A Drift-Flux Model For Upward Two-Phase In Pipes With High Velocity Flows, Woochan Lee

LSU Doctoral Dissertations

This study proposes the evaluation and development of a drift-flux model for upward two-phase high-velocity flow in large diameter pipes. A case where the proposed model is applicable is WCD (Worst-Case-Discharge) calculations for offshore wells. WCD assumes relatively larger pipe diameters and higher flow rates than the flow experiments at laboratory conditions utilized to validate and develop most of the flow models available in the literature.

Most of the two-phase flow models describe flow regime transitions as discrete processes by assigning the required void fraction or velocity for each flow regime transition. Therefore, for each flow regime, flow-regime-dependent correlations or …

Branching Off: New Insight Into Lysosomes As Tubular Organelles, K A. Bohnert, A E. Johnson

Faculty Publications

Lysosomes are acidic, membrane-bound organelles that play essential roles in cellular quality control, metabolism, and signaling. The lysosomes of a cell are commonly depicted as vesicular organelles. Yet, lysosomes in fact show a high degree of ultrastructural heterogeneity. In some biological contexts, lysosome membranes naturally transform into tubular, non-vesicular morphologies. Though the purpose and regulation of tubular lysosomes has been historically understudied, emerging evidence suggests that tubular lysosomes may carry out unique activities, both degradative and non-degradative, that are critical to cell behavior, function, and viability. Here, we discuss recent advances in understanding the biological significance of tubular lysosomes in …

Literacy's Levels: An Analysis Of Neoliberal Literacy Sponsorship In The U.S., Misty Dawn Fuller

LSU Doctoral Dissertations

While much scholarship has considered Deborah Brandt’s concept of sponsors of literacy, there remains a need to consider relationships between literacy sponsors and larger implications of literacy sponsorship at national and institutional levels. Utilizing academic theories, U.S. federal government budgets and financed reports, and discoursal analysis, this dissertation investigates literacy sponsorship at the federal, postsecondary institutional, postsecondary institutional writing programmatic, and individual levels to tease out how, and in what ways, through “enabling” and “supporting” literacy these sponsors also” regulate, suppress, and withhold literacy” (Brandt 166). Rhetorical analysis determines that, at the U.S. federal level, literacy is promoted as a …

Paraventricular Vitamin D Receptors Are Required For Glucose Tolerance In Males But Not Females, Jessie Beck, Silvania Da Silva Teixeira, Keisha Harrison, Gabrielle Phillips, Yanlin He, Stephanie Sisley

Division of Basic Science Faculty Publications

When delivered directly into the brain, vitamin D, can improve glucose levels in male mice. Additionally, the loss of the vitamin D receptor (VDR) in male mice’s paraventricular hypothalamus (PVH) results in impaired glucose tolerance. Data in humans shows that low vitamin D levels are detrimental to glucose homeostasis, an effect that may be more prominent in men. However, it is unknown if vitamin D action in the brain is required for normal glucose regulation in female mice. This study shows that in both viral and genetic models, male mice with obesity and PVH VDR loss have impaired glucose tolerance …

Places To Live: A Multidisciplinary Approach To Modern Maya Houses In Yucatan, Mexico, Virginia J. Ochoa-Winemiller

LSU Doctoral Dissertations

In 1938, Robert C. Wauchope’s Modern Maya Houses provided the first detailed description of traditional rural housing for the Maya area. Until today, no research has attempted to test Wauchope’s notion of cultural continuity in Maya domestic architecture from the prehistoric past up to the time of his pioneering study. By examining data from three municipios located in the state of Yucatan, Mexico, I compared contemporary information collected during visits to residential areas with that published by Wauchope in 1938. An integrated approach to data gathering and analysis, that is, a combination of interviews, questionnaires, archaeological survey, and geographic information …

Ligers Interferometric Survey Of M Dwarf Diameters, Tyler Gregory Ellis

LSU Doctoral Dissertations

In this dissertation, I present the largest single collection of M dwarf stellar radii in over a decade and contextualize these measurements with the systematic model discrepancies. The measurements of stellar angular diameters are also important in the quantification of the properties of exoplanets. In order to estimate the property of the exoplanet, it is first necessary to quantify the properties of the planet's host star. Using the survey results complemented with previous direct observations of the angular diameters of low mass stars, I develop updated updated surface brightness relationships. These relationships allow predictions of angular diameters using easy to …

A Data-Based Framework For Monitoring And Controlling Particulate Systems, Vidhyadhar Manee

LSU Doctoral Dissertations

One of the limitations of conventional monitoring tools in crystallization is the inability to deal with high solids concentration. Image-based monitoring, in which RGB images of the solution are captured and analyzed by an object detection software, has been a promising alternative. The software used in these tools primarily depends on hand-coded heuristics to distinguish between the signal and the noise. With the recent success of supervised deep learning, a newer paradigm has emerged in which the heuristics can be learnt from labeled images. This approach is founded on the idea that it is easier to develop labels for data …

A recent Perspective article described the "carbohydrate-insulin model (CIM)"of obesity, asserting that it "better reflects knowledge on the biology of weight control"as compared with what was described as the "dominant energy balance model (EBM),"which fails to consider "biological mechanisms that promote weight gain."Unfortunately, the Perspective conflated and confused the principle of energy balance, a law of physics that is agnostic as to obesity mechanisms, with the EBM as a theoretical model of obesity that is firmly based on biology. In doing so, the authors presented a false choice between the CIM and a caricature of the EBM that does not …

Midbrain dopamine (DA) and serotonin (5-HT) neurons regulate motivated behaviors, including feeding, but less is known about how these circuits may interact. In this study, we found that DA neurons in the mouse ventral tegmental area bidirectionally regulate the activity of 5-HT neurons in the dorsal raphe nucleus (DRN), with weaker stimulation causing DRD2-dependent inhibition and overeating, while stronger stimulation causing DRD1-dependent activation and anorexia. Furthermore, in the activity-based anorexia (ABA) paradigm, which is a mouse model mimicking some clinical features of human anorexia nervosa (AN), we observed a DRD2 to DRD1 shift of DA neurotransmission on 5-HTDRN neurons, which …

Coronavirus disease 2019 (COVID-19) remains a global public health threat. Hence, more effective and specific antivirals are urgently needed. Here, COVID-19 hyperimmune globulin (COVID-HIG), a passive immunotherapy, is prepared from the plasma of healthy donors vaccinated with BBIBP-CorV (Sinopharm COVID-19 vaccine). COVID-HIG shows high-affinity binding to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein, the receptor-binding domain (RBD), the N-terminal domain of the S protein, and the nucleocapsid protein; and blocks RBD binding to human angiotensin-converting enzyme 2 (hACE2). Pseudotyped and authentic virus-based assays show that COVID-HIG displays broad-spectrum neutralization effects on a wide variety of SARS-CoV-2 variants, …

Crop landraces have unique local agroecological and societal functions and offer important genetic resources for plant breeding. Recognition of the value of landrace diversity and concern about its erosion on farms have led to sustained efforts to establish ex situ collections worldwide. The degree to which these efforts have succeeded in conserving landraces has not been comprehensively assessed. Here we modelled the potential distributions of eco-geographically distinguishable groups of landraces of 25 cereal, pulse and starchy root/tuber/fruit crops within their geographic regions of diversity. We then analysed the extent to which these landrace groups are represented in genebank collections, using …

The Potential For Bias Across Gps-Accelerometer Combined Wear Criteria Among Adolescents, Maura M. Kepper, Amanda E. Staiano, Stephanie T. Broyles

Population and Public Health Science Faculty Publications

Physical activity has many health benefits, yet a large portion of our population is not meeting recommendations. Using accelerometry and global positioning systems (GPS) to accurately measure where people are active and to identify barriers and facilitators of activity across various settings will inform evidence-based policies and interventions to improve activity levels. Criteria for sufficient accelerometry data (e.g., number of days, minimum hours in a day) to accurately monitor free-living physical activity in adults and children have been widely studied, implemented, and reported by researchers. However, few best practice recommendations for researchers using GPS have been established. Therefore, this paper …

Variation And Predictors Of Gross Motor Coordination Development In Azorean Children: A Quantile Regression Approach, Sara Pereira, Flávio Bastos, Carla Santos, José Maia, Go Tani, Leah E. Robinson, Peter T. Katzmarzyk

We estimated sibling resemblance in health-related physical fitness (PF) and examined how individual characteristics and shared natural environment accounted for sibling similarities. The sample comprised 656 sibling pairs and 102 triplets (6–15 years of age), from three geographical areas of Peru. PF components included morphological (waist circumference, sum of skinfolds), muscular (handgrip strength, standing long jump), and motor (shuttle-run). Body mass index (BMI) and somatic maturation were also assessed. In general, sibling intraclass correlations differed significantly across sib-ship types for waist circumference and handgrip strength but were the same for sum of skinfolds, standing long jump, and shuttle-run. Further, in …
