Objective: Neuropsychiatric symptoms (NPS) are common in mild cognitive impairment (MCI) and even more in Alzheimer's disease (AD). The symptom-based cluster including nighttime disturbances, depression, appetite changes, anxiety, and apathy (affective and vegetative symptoms) was associated with an increased risk of dementia in MCI and has common neuroanatomical associations. Our objective was to investigate the differences in brain morphology associations with affective and vegetative symptoms between three groups: cognitively normal older adults (CN), MCI and AD. Material and Methods: Alzheimer's Disease Neuroimaging Initiative data of 223 CN, 367 MCI and 175 AD, including cortical volumes, surface areas and thicknesses and …

Exploring The Experiences Of Pregnant Women In The U.S. During The First Year Of The Covid-19 Pandemic, Courtney E. Williams, Dana Berkowitz, Heather M. Rackin

Faculty Publications

In this paper, we integrate the stress process model with symbolic interactionism to frame our analysis of interviews with 35 women who were pregnant and/or gave birth during the first year of the Covid-19 pandemic. We detail three stressors, highlight their variation, and discuss how they coped with these stressors. Women reported having to navigate contradictory information about the public health crisis, but Black participants simultaneously endured added strain from a heightened awareness of racialized violence. To cope with an overabundance of precarious and contradictory messages, some women sought out information (i.e., information gatherers), others eschewed information (i.e., information avoiders), …

An Examination Of Frontline Employee–Customer Incidental Similarities In Service Failure And Recovery Contexts, Kristina K. Lindsey-Hall, Susana Jaramillo, Thomas L. Baker, Daniel G. Bachrach

Faculty Publications

Developing rapport during the “moment of truth” when frontline employees (FLEs) interact with customers has long been an important topic for researchers and managers. We suggest incidental similarities—seemingly trivial shared points of comparison between customers and FLEs—can play a vital role during this juncture in service failure and recovery contexts. Across two experimental studies, we investigate several relationships impacted by the presence or absence of an incidental similarity between FLEs and customers for their effect on satisfaction and repatronage intentions. Results suggest incidental similarities can reduce failure attributions toward service providers and improve these important customer-related outcomes (study 1). Results …

Voting In The Mall - Understanding Political Consumerism In The United States And Europe, Kwadwo Poku-Agyemang

LSU Doctoral Dissertations

This dissertation explores the various traits that predispose individuals or groups to participate in political boycotts by refraining from purchasing goods and services from companies with the goal of promoting their political beliefs and goals. Specifically, this research considers the effects of political ideology, attitudes toward historically-marginalized groups, and identification with grievance groups shape self-reported participation in political consumerism in the United States and Europe. Using data from the 2016 and 2020 American National Election Survey and the eighth, nineth and tenth rounds of the European Social Survey, I find that although political consumerism has been seen as a liberal …

Confirmatory Factor Analysis Of The Adult Coping Inventory, Kristen Ashley Hollas

LSU Doctoral Dissertations

There are few psychometrically sound measures that assess coping in adults. For example, a widely used measure of coping, the COPE, has highly unstable sub-scales and was developed using a homogenous sample (Lyne & Roger, 2000). Because of these limitations, the Adult Coping Inventory (ACI) was developed. The ACI is a 57-item measure that contains five factors including Problem Solving, Mindfulness, Maladaptive Coping, Social Support and Avoidance. Initial reliability and validity analyses demonstrate good construct, concurrent and incremental validity. The current study involved conducting a confirmatory factor analysis to confirm the factor structure of the ACI. The participant sample consisted …

Effects Of Research Dissemination Vehicle Use On Preservice Teacher Candidate Knowledge Acquisition, Allie Jenkins Boquet

LSU Doctoral Dissertations

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 …

Ecological Validity Of Immersive Virtual Environment Experiments On Human Thermal State And Behavioral Intentions: Experimental Protocol Factors, Girish Rentala

LSU Doctoral Dissertations

Using immersive virtual environment (IVE) based experiments to investigate human thermal states and thermal adaptive behaviors during the building design phase could help identify potential comfort issues and enable designers to optimize building performance cost-effectively before the actual building construction. However, to effectively utilize IVEs to study thermal states/adaptive behaviors, it is crucial to ensure the ecological validity of IVE experiment protocols. This entails accurately representing in-situ (real) environments within IVEs and establishing comparability and generalizability of data collected under different thermal stimuli between IVE and in-situ environments. Existing thermal stimuli based IVE studies have not effectively evaluated the ecological …

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 …

Androgynous Figures On Etruscan Cista Handles From Praeneste, Melanie Naples

LSU Master's Theses

Muscular women and effeminate men adorn the lids of Etruscan Cistae found in Praeneste (modern Palestrina, 23 miles southeast of Rome, Italy). Cistae (Latin plural of cista) are storage containers used by the Etruscans for women’s beauty items. This thesis focuses on the androgynous, mostly nude, figures that serve as handles and are often displayed in pairs. These pairs frequently depict a man and a woman together and androgynous qualities are usually emphasized on the female figures. Discussions of the androgynous body in the ancient world have centered around Greece and Rome. Only recently (Sandhoff 2007, 2009, 2011), scholarship has …

Foreign State Images And Popular Foreign Policy Constraints, Cana Kim

LSU Doctoral Dissertations

When making equivalent foreign policy decisions, why do national leaders sometimes face stronger constraints from the mass public? A growing number of studies recognize the effect of public opinion on foreign policy decision-making. While not having the authority to formulate foreign policy, the mass public can hold national leaders accountable in formal and informal ways. However, public opinion does not function as an automatic constraint on national leaders. Instead, public opinion provides more powerful constraints on foreign policy decision-making conditional on the context shaping popular beliefs and social behavior.

In this dissertation, I delve into the public perceptions of domestic …

An Evaluation Of Procedures To Increase Medical Device Compliance, Sarah Christian Holmes

LSU Doctoral Dissertations

Behavioral interventions have been implemented to increase compliance with medical devices across patient populations and target devices. Intervention to increase medical device compliance (MDC) can involve a variety of components, including different reinforcement, graduated exposure, extinction, and punishment with varying degrees of acceptability and feasibility. In the current study, we compared the effects of noncontingent (NCR) versus synchronous reinforcement schedules on the duration of MDC and latency to device removal with KN95 face masks with 2 patients with Autism Spectrum Disorder. Following an initial baseline phase demonstrating that both participants engaged in compliance for less than 5 min, we used …

Active Transportation, Context, And Community Participation: Engaged Citizens And Destination-Based Walking And Biking, Jessica Stroope

LSU Doctoral Dissertations

Active transportation is associated with many benefits, including improved health outcomes, higher commuting satisfaction, lower pollution, reduced traffic, and social capital. One understudied area of research on active transportation and social capital is the relationship between active transportation and community participation. Although prior work has established a connection, little is known about the contexts in which this relationship may occur, or about how active transportation may affect the relationship between a context and community participation.

The purpose of Chapter 3 is to examine how active transportation may mediate the relationship between perceptions of place and community participation. Significant work has …

Measuring Food Literacy Among Limited-Resourced Adults, Emelia Clement

LSU Doctoral Dissertations

Food literacy is the interrelated knowledge, skills and behaviors needed to plan and manage, select, prepare, and eat healthy food. It is positively associated with improved consumption of nutritious diets, and can be beneficial to limited-resource adults, who are often at risk for chronic diet-related diseases. Valid instruments for measuring food literacy in this population are scarce but urgently needed. The Eating and Food Literacy Behavior Questionnaire (EFLBQ) can be used to measure food literacy among limited-resource audiences.

Part one of this study aimed to determine the fitness of the EFLBQ to measure food literacy in limited-resource adults. A convenience …

Don't Forget Me: A Discussion On Social Memory And Commemoration, Anfernee Murray

LSU Master's Theses

This thesis examines the relationship between social memory and social identity development among groups who share contested interpretations of their shared social memory. With social memories being a collaborative process that requires consensus and compromise, there arises conflict when groups are divided in deciding on what event of their shared history is relevant to remember - for it is these memories that influence and shape how a group identifies itself.

For Black Americans, this contention arises in the conversations surrounding the difficult and traumatic histories of their enslaved ancestors by the ancestors of their white counterparts. This is further complicated …

Alcea consists of prints, drawings, and installations that showcase the hollyhock in each stage of its transition.

The Psychological Impact Of Adolescent Violence Exposure: The Roles Of Coping And Social Support, Kelsey Gnade Coulthard

LSU Doctoral Dissertations

Research demonstrates that children and adolescents experience a wide range of exposure to violence with rates ranging from 20% and 50% (Finkelhor & Dziuba-Leatherman, 1994; Finkelhor et al., 2005; Zimmerman & Posick, 2016). Violence exposure has been associated with several negative outcomes including biological, psychological, family-based, and academic problems. Further, studies have examined potential protective factors that may buffer against these consequences, with inconsistent results surrounding the roles of coping and social support. However, many of these studies use either an overly generalized definition of both violence exposure and/or social support or use very specific type of violence within a …

Eve Leaving The Garden, Norma L. Colby Ms.

LSU Master's Theses

This body of work serves as an investigation into the concepts and burdens that, as a female millennial, impact me regularly. As the door to my education closes, I turn to a much bigger world with endless possibilities and responsibilities. With these overwhelming prospects, I find myself reflecting on how our society has progressed and worsened to arrive here today. I continue to question the passing down of systemic burdens, politics, and gender roles of women in the 21^st century. Eve Leaving the Garden is a collection of textile works, photographs, and sculptures that serve as an exploration of …

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 …

Navigating Political Discussions Online: The Role Safe Spaces Play In Women's Political Participation On Twitter, Ayla Oden

LSU Doctoral Dissertations

This study analyzes how women navigate political discussions online. Social media breeds high-conflict spaces where threats and incivility are more likely to persist. To avoid ad hominem attacks or harassment from online, male users, women may be more likely to use “safe spaces” online, including stereotypically feminine conversations regarding “women’s issues.” The purpose of this study is to analyze how women discuss politics online and whether there are differences in the issues discussed by men and women on Twitter. Using three studies, I examined these differences and their relationship to the threats women face online and their political behavior offline. …

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. …

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.

Gifts And Commodities: A Dialectical Thought Experiment For Sublation, Ruirui Zhang, Joseph D’Andrea, Chunmin Lang

Faculty Publications

The core motivation for this study is the realization that the Sustainable Development Goals (SDGs) encounter temporary obstacles, conflicts, or inconsistencies that impede progress and generalization. According to the authors, sustainable development across social, environmental, and economic dimensions is unlikely to occur without redefining the meaning and recalibrating the metrics used to measure commodities. These meanings and metrics must align with values such as general reciprocity, morality, and the common good, going beyond mere calculations of means and ends and personal preferences. The research has three primary objectives: first, to compare and reassess the meanings and responsibilities assigned to “items” …

Integrating Germplasm Repositories Into Oyster Aquaculture Systems At The Pathway, Center, And Network Levels, Sarah R. Bodenstein

LSU Doctoral Dissertations

Germplasm repositories offer many potential benefits to commercial farm operations, including preserving genetic resources and increasing production capabilities. Aquaculture industries have yet to take advantage of repository storage despite decades of research evaluating cryopreservation protocols. Eastern oysters (Crassostrea virginica), for example, are a useful research species when addressing this problem. Oysters are an economically important aquaculture species and a high-throughput cryopreservation method for oysters already exists. To address the gap between protocol research and commercial application a different approach is necessary that can analyze the requirements of repository development at multiple organizational levels. The goal of this dissertation was to …
