This study provides information on how EBPs can be disseminated to education practitioners for the purpose of knowledge acquisition. With a well-established research-to-practice gap in the field of education, this study determined which research dissemination vehicle, practitioner journal article, informational video, or textbook chapter, allowed for the highest acquisition of knowledge for preservice teachers.

The purpose of this study was to determine how the use of three different research dissemination vehicles, 1) practitioner journal articles, 2) informational videos, and 3) textbook chapters, impacts acquisition of knowledge of the EBP, instructional feedback, when utilized by preservice teacher candidates as well as …

A History Of The Construction And Financing Of Division I Football Bowl Subdivision And Ivy League Stadia: An Ideal-Type On Financial Modernization, Tiffany E. Demiris

LSU Doctoral Dissertations

This dissertation seeks to introduce financial modernization as a distinct subcategory of modernization and present practical applications for sport managers. Modernization literature has shown that, as society advances, levels of complexity increase. Modernization is generally concerned about the impact of technology, transportation, financial operations, and the reduction of risk in society (Seifried & Novicevic, 2017). These facets are not only important to established modernization subcategories, reflexive and ecological, but are also applicable to financial systems and demonstrate how financial modernization is both complementary and a distinct type of modernization. It is possible to take larger risks over time because so …

Plato's Republics: A Dramatic Interpretation Of The Early Cities In Plato's "Republic", Simeon Burns

LSU Doctoral Dissertations

This dissertation will demonstrate a new methodological approach to reading Plato’s Republic. I develop and apply a dramatic, dynamic hermeneutic to Book II and part of Book III in the text. This method holds that each speech is the product of a preceding agreement or disagreement between two speakers. Agreements lead to the argument’s advancement and disagreements result in a regression to a previous agreement from which to restart the exchange. The focus section is largely on the early exchange Socrates has with Adeimantus. I argue that Socrates is an unwilling participant in the famous discussion on the meaning …

The Influence Of Selected Personal And Academic Demographic Characteristics On Retention From Fourth To Fifth Semester Of Enrollment Among Traditional-Age Undergraduate Students At A Research Extensive University In The Southern Portion Of The United States, Tammy R. Millican

LSU Doctoral Dissertations

While many Americans may be questioning the value of a college degree due to rising costs, on virtually every measure of economic well-being and career attainment—from personal earnings to job satisfaction to the share employed full time—young college graduates are outperforming their peers with less education. Yet college dropout rates indicate that up to 32.9% of undergraduates do not complete their degree program, which has a financial impact on both students and the universities and colleges where they enroll (Hanson, 2022).

Historically, students who leave college before completing a baccalaureate degree are no better qualified than those with a high …

Exploring Machine Learning In Deep Foundation And Soil Classification Application, Mohammad Moontakim Shoaib

LSU Master's Theses

The applicability of several Machine Learning (ML) models was explored in this research to predict the ultimate capacity and load-settlement behavior of axially loaded single-driven piles from Cone Penetration Test (CPT) data. Additionally, a common CPT-based soil behavior type (SBT) classification system was reproduced using those ML models. Eighty static pile load tests and corresponding CPT data close to those pile locations were collected from 34 sites in Louisiana for the deep foundation application. On the other hand, 70 CPT soundings were taken in 14 different parishes across Louisiana for the soil classification application. Specifically, tree-based ML models such as …

Angular Correlations In The Β Decay Of B 8: First Tensor-Current Limits From A Mirror-Nucleus Pair, A. T. Gallant, N. D. Scielzo, G. Savard, J. A. Clark, M. Brodeur, F. Buchinger, D. P. Burdette, M. T. Burkey, S. Caldwell, J. E. Crawford, A. Czeszumska, C. M. Deibel, J. Greene, D. Heslop, T. Y. Hirsh, A. F. Levand, B. Longfellow, G. E. Morgan, P. Mueller, R. Orford, S. Padgett, N. Paul, A. Pérez Galván, A. Reimer, R. Segel, K. S. Sharma, K. Siegl, L. Varriano, B. J. Zabransky

Faculty Publications

We present the first measurement of the α-β-ν angular correlation in the Gamow-Teller β+ decay of B8. This was accomplished using the Beta-decay Paul Trap, expanding on our previous work on the β- decay of Li8. The B8 result is consistent with the V-A electroweak interaction of the standard model and, on its own, provides a limit on the exotic right-handed tensor current relative to the axial-vector current of |CT/CA|2< 0.013 at the 95.5% confidence level. This represents the first high-precision angular correlation measurements in mirror decays and was made possible through the use of an ion trap. By combining this B8 result with our previous Li8 results, we demonstrate a new pathway for increased precision in searches for exotic currents.

Uniqueness Of Relaxation Times Determined By Dielectric Spectroscopy, Mengchun Wu, Karin J. Bichler, Bruno Jakobi, Gerald J. Schneider

Faculty Publications

Dielectric spectroscopy is extremely powerful to study molecular dynamics, because of the very broad frequency range. Often multiple processes superimpose resulting in spectra that expand over several orders of magnitude, with some of the contributions partially hidden. For illustration, we selected two examples, (i) normal mode of high molar mass polymers partially hidden by conductivity and polarization and (ii) contour length fluctuations partially hidden by reptation using the well-studied polyisoprene melts as example. The intuitive approach to describe experimental spectra and to extract relaxation times is the addition of two or more model functions. Here, we use the empirical Havriliak-Negami …

Development Of Cost-Effective Restriping Strategies For Thermoplastic Pavement Markings Used In Hot And Humid Climate, Elise Mansour

LSU Master's Theses

Because of the limited highway state budget, most transportation agencies restripe their thermoplastic pavement markings based on a fixed schedule or based on visual inspection. However, these restriping strategies might be questionable in terms of efficiency and cost. Some studies have developed degradation models to predict the retroreflectivity of thermoplastic markings based on key variables. Yet, most of the developed models had low prediction accuracy (R² as low as 0.1) and sometimes was not reported, which placed little confidence in their use. Therefore, the objective of this study was to evaluate the field performance and develop cost-effective restriping strategies …

Sucrose Demand And Essential Value In Mice With Early-Life Exposure To Risperidone, Megan Federoff

LSU Master's Theses

Second-generation antipsychotics (SGAs), such as risperidone, are widely prescribed to children, but the long-term effects of SGA treatment are not well understood. This study investigated the impact of early-life risperidone treatment on sucrose demand in mice in adulthood. Mice were administered risperidone or vehicle from postnatal day (PND) 33 to 60 and trained in adulthood (>PND 120) to nose poke for a sucrose solution reinforcer. The fixed ratio (FR) value (the number of responses required to produce sucrose delivery; the “price” of sucrose) was varied from 1 to 45, and the resulting consumption versus FR value data were analyzed …

Bayesian Order Constrained Adaptive Design For Phase Ii Clinical Trials Evaluating Subgroup-Specific Treatment Effect, Mu Shan, Beibei Guo, Hao Liu, Qian Li, Yong Zang

Faculty Publications

The “one-size-fits-all’’ paradigm is inappropriate for phase II clinical trials evaluating biotherapies, which are often expected to have substantial heterogeneous treatment effects among different subgroups defined by biomarker. For these biotherapies, the objective of phase II clinical trials is often to evaluate subgroup-specific treatment effects. In this article, we propose a simple yet efficient Bayesian adaptive phase II biomarker-guided design, referred to as the Bayesian-order constrained adaptive design, to detect the subgroup-specific treatment effects of biotherapies. The Bayesian order constrained adaptive design combines the features of the enrichment design and sequential design. It starts with a “all-comers” stage, and subsequently …

Stakeholder Perceptions About Incorporating Externalities And Vulnerability Into Benefit–Cost Analysis Tools For Watershed Flood Risk Mitigation, Thomas H. Douthat, Fahmida Akhter, Rachelle Sanderson, Jerrod Penn

Faculty Publications

Multi-scalar climate hazards in watersheds and growing consideration regarding equity call for innovation in how agencies evaluate and prioritize mitigation and adaptation projects. Benefit–Cost Analysis (BCA) is one approach that is increasingly being applied to decision-making (i.e., FEMA BCA toolkit), but that has not been applied to watershed and equity-based flood management initiatives. This paper addresses this topic and presents a case study evaluating projects for watershed flood and climate mitigation projects by the Louisiana Watershed Initiative (Louisiana, USA). Through semi-structured interviews with stakeholders and practitioners, we found that BCA tool design must be embedded in the program and policy …

Niche Specialization And Community Niche Space Increase With Species Richness In Filter-Feeder Assemblages, Irene Sánchez González, Garrett W. Hopper, Jamie R. Bucholz, Megan E. Kubala, Jeffrey D. Lozier, Carla L. Atkinson

Faculty Publications

Ecological theory posits that higher species richness should be associated with greater exploitation of resources and niche packing resulting from either increasing species niche overlap or specialization of species' niches. Research evaluating niche theory in animals tends to focus on organisms among functional feeding guilds, while resource partitioning might be more critical within functional groups. Freshwater mussels (Family: Unionidae) are a diverse and imperiled group of animals that are ideal models to test niche occupancy due to their functional similarity as filter-feeders and their occurrence in spatially and temporally stable multispecies aggregations. We evaluated the relationship between species richness and …

Group Cognitive Behavioral Therapy For Substance Use Disorders Among Psychiatric Inpatients In A Medically Underserved Area: An Intervention For Opioid Misuse, Julia D. Buckner, Caroline R. Scherzer, Kathleen A. Crapanzano, Paige E. Morris

Faculty Publications

Objectives: Opioid misuse is a serious public health concern, yet few people seek treatment for this condition. Hospitals may be one opportunity to identify those with opioid misuse and to teach them skills to help manage their opioid misuse upon discharge. We tested the relationship between opioid misuse status and motivation to change substance use among patients admitted with substance misuse to an inpatient psychiatric unit in a medically underserved area in Baton Rouge, Louisiana, who attended at least 1 group session of motivation enhancement therapy combined with cognitive behavioral therapy (MET-CBT) from January 29, 2020, through March 10, 2022. …

Effect Of Sleep Restriction On Insulin Sensitivity And Energy Metabolism In Postmenopausal Women: A Randomized Crossover Trial, Prachi Singh, Robbie A. Beyl, Jacqueline M. Stephens, Robert C. Noland, Allison J. Richard, Anik Boudreau, R. Caitlin Hebert, Eric Ravussin, Josiane L. Broussard, Marie Pierre St-Onge, Kara L. Marlatt

Division of Basic Science Faculty Publications

Objective: The aim of this study was to investigate the effect of sleep restriction (SR) on insulin sensitivity and energy metabolism in postmenopausal women. Methods: In a randomized crossover trial, 14 women underwent four nights of habitual sleep (HS, 100% normal sleep) and SR (60% of HS) while following a eucaloric diet. Outcomes included the following: (1) insulin sensitivity by hyperinsulinemic-euglycemic clamp, defined as the glucose infusion rate (GIR); (2) resting metabolism and substrate oxidation by indirect calorimetry; and (3) glucose, insulin, and C-peptide concentrations following a standard meal test. Results: Nine postmenopausal women (mean [SD], age 59 [4] years, …

Tnfα Effects On Adipocytes Are Influenced By The Presence Of Lysine Methyltransferases, G9a (Ehmt2) And Glp (Ehmt1), Ashley A. Able, Allison J. Richard, Jacqueline M. Stephens

Division of Basic Science Faculty Publications

Impaired adipocyte function contributes to systemic metabolic dysregulation, and altered fat mass or function increases the risk of Type 2 diabetes. EHMTs 1 and 2 (euchromatic histone lysine methyltransferases 1 and 2), also known as the G9a-like protein (GLP) and G9a, respectively, catalyze the mono- and di-methylation of histone 3 lysine 9 (H3K9) and also methylate nonhistone substrates; in addition, they can act as transcriptional coactivators independent of their methyltransferase activity. These enzymes are known to contribute to adipocyte development and function, and in vivo data indicate a role for G9a and GLP in metabolic disease states; however, the mechanisms …

Learning About Our Vices From Devices: A Model Of Individual Learning With An Application To Consumer Food Waste, Danyi Qi, Brian E. Roe, John W. Apolzan, Corby K. Martin

Clinical Research Faculty Publications

We formulate an empirical learning model suitable for understanding individual behavioral responses to personal devices and sensors. We estimate this model using data collected about personal decisions of food selection, intake, and waste during a study in which users photographed their meal selections and plate waste over the course of a week with a cell phone. We found substantial learning-by-doing effects in plate-waste reduction: Those who document greater plate waste in their photographs waste less on subsequent days. Further, we identified that participants reduced plate waste by learning to eat more rather than by learning to select less food.

Latino Paradox Or Black Exception? Race, Ethnicity, And Crime In The 21st Century, Edward S. Shihadeh, Raymond E. Barranco

Faculty Publications

George Floyd’s murder by a Minnesota police officer sparked outrage, protests, and a re-evaluation of racial inequities in America. Within criminology, we argue, that re-evaluation should include the Latino Paradox, the idea that Latino communities are an exception—a paradox—in that, while they face economic deprivation, they also possess a magical something that makes them resistant to social problems like crime. Unfortunately, this compels the more delicate question; what is the deficiency in Black communities that makes them so vulnerable to crime? However, as we argue here, the Latino Paradox forces a false comparison. Its assumptions with respect to crime are …

Cereal Rye Cover Crop Seeding Method, Seeding Rate, And Termination Timing Effects Corn Development And Seedling Disease, Fernando M. Marcos, Jyotsna Acharya, Md Rasel Parvej, Alison E. Robertson, Mark A. Licht

Faculty Publications

Cover crops decrease nutrient leaching from high-input cropping systems and improve soil quality. In Iowa, cereal rye (CR, Secale cereale L.) is the most adopted species due to its winter hardiness, high biomass productivity, and low cost. Field management of CR is still not completely understood, and as its adoption brings more complexity to farmers, especially with the uncertain effects on corn (Zea mays L.) yields, adoption is slow. Additionally, cover crops immobilize N and increase the inoculum of pathogens such as Pythium spp. A 2-year field experiment was conducted at three locations in Iowa investigating the effect of two …

Amazonian Birds In More Dynamic Habitats Have Less Population Genetic Structure And Higher Gene Flow, Oscar Johnson, Camila C. Ribas, Alexandre Aleixo, Luciano N. Naka, Michael G. Harvey, Robb T. Brumfield

Faculty Publications

Understanding the factors that govern variation in genetic structure across species is key to the study of speciation and population genetics. Genetic structure has been linked to several aspects of life history, such as foraging strategy, habitat association, migration distance, and dispersal ability, all of which might influence dispersal and gene flow. Comparative studies of population genetic data from species with differing life histories provide opportunities to tease apart the role of dispersal in shaping gene flow and population genetic structure. Here, we examine population genetic data from sets of bird species specialized on a series of Amazonian habitat types …
