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” …

Universal Screening For Student Mental Health: Selection Of Norming Sample As A Determinate Of Risk Status, Meagan Zeitvogel

LSU Master's Theses

The prevalence of student mental health concerns has increased the need for universal mental health screening. In turn, students may have increased access to services and support. Some screeners determine risk status by comparing student scores to norming samples that can be based solely on age (i.e., combined-gender) or on age and gender (i.e., separate-gender). Combined-gender norming samples assign risk status based on typical emotional and behavioral functioning across development. Separate-gender norming samples assign risk status based on developmental and biological differences between boys and girls. Currently, there is no research determining if students’ risk status changes based on norming …

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 …

Utilizing A Text-Mining Approach To Investigate Consumers’ Perception Of Secondhand Fashion Consumption: Mass-Market Vs. Luxury Market, H M Rakib Ul Hasan

LSU Doctoral Dissertations

The dissertation aimed to investigate (i) the difference in consumer perception between the mass-market and luxury market of secondhand fashion services, (ii) determine the types of value and strategies that can be adopted into mass-market SHF from luxury SHF business platforms, (iii) investigate the word-of-mouth communication of mass-market SHF consumers, and (iv) investigate the consumer perception of the ‘quality’ and ‘fashionability’ of the mass-market SHF product. Two studies were designed to address the research questions due to the nature of available data. The data were collected from third-party consumer review sites where consumers can review their perception of secondhand fashion …

Apocalypse Then And Now: Narrative Influence And Thematic Subversion Of Victorian Literature In Modern American War Narratives, Douglas James Scully

LSU Doctoral Dissertations

In this dissertation, I argue that by looking at the lasting impact of Victorian war literature on a variety of modern media, one can see that an increased cultural awareness of trauma has led to less humane depictions of the traumatized. The multitude of Sherlock Holmes adaptations produced and set in various time periods and covering assorted wars serves as a strong example in my first chapter of how a Victorian-produced text can have a lingering impact, and the veteran Watson serves as a strong tool for adaptors to use when commenting on the shifting nature of war and the …

The Reality Of Teaching English Virtually: Esl Teachers' Perspectives And Experiences During The Covid-19 National Pandemic, Natalia Guerrero

LSU Doctoral Dissertations

This study examined the dilemma ESL teachers experienced as the educational system shifted from the usual modus operandi of in-person lessons to the uncharted virtual learning environment (VLE). ESL teachers, in one of the largest urban districts in Louisiana, accumulated additional roles and responsibilities that were unique to the teachers of the English learner (EL) population enrolled at their schools.

Data collected to answer the research questions were the product of single and focus group’s interviews with five ESL elementary and middle school teachers in Freedom District. State and district emergency response to COVID-19 guidelines, along with instructional artifacts, were …

Division I Softball Athletes' Perceptions On Stress, Coping, Performance, And Mental Health, Rhianna Weall

LSU Master's Theses

Collegiate athletes face numerous stressors in both athletic and academic areas of performance. Their perceptions of situations dictate coping responses and their ability to enact behavior or implement strategies to manage stress levels. This study investigated perceived stress and coping strategies using semi-structured in-person interviews with five current NCAA Division I softball players. Three main themes emerged from the interviews: (a) Pressure is Privilege, (b) Team Dynamic and Identity Development, (c) Softball-Centrism. In the first theme, pressure is viewed as a positive aspect and as an opportunity to perform in areas of high and low levels of confidence. Within the …

"Feeling Who I Am": Developing A Theory Of Intersectional Emotional Expression In The Workplace, Terrance Boyd

LSU Doctoral Dissertations

Scholars have studied how employs engage in emotional labor with customers, coworkers, and supervisors in the workplace for over twenty years (Grandey, 2000; Hochschild, 1983; Kim, Bhave, & Glomb, 2013; Thomas, Olien, Allen, Rogelberg, & Kello, 2018). A considerable amount of the emotional labor literature explores the impact of gender in the hypothesized relationships, largely positing that women engage more often in emotional labor and feel the consequences more severely than men (e.g., Scott & Barnes, 2011; Simpson & Stroh, 2004; Ward, McMurray, & Sutcliffe, 2020). Although important and enlightening, this approach is limited in recognizing the more complete spectrum …

A Critique Of Aristotle: Countervoluntary Action And Moral Injury, Melissa Altsman

LSU Master's Theses

“A Critique of Aristotle: Countervoluntary Action and Moral Injury,” is a critique of Aristotle’s view that countervoluntary action does not affect character. I argue that a countervoluntary action can affect character when said action leads to a moral injury. Throughout this critique I use military experiences of moral injury to bolster my argument. This critique focuses on Aristotle’s Nicomachean Ethics, and is directed at his Nicomachean Ethics specifically. The upshot of my critique is to not only argue that countervoluntary action affects character, but to spotlight specifically why it is character affecting. Essentially, my aim is to call attention …

The Social Support Experiences Of Attention-Deficit/Hyperactivity Disorder (Adhd) Adults, Lindsay A. Duede, Colter Ray

LSU Master's Theses

Social support researchers commonly recognize that support is most useful when it matches the needs and desires of those receiving it. Yet, the majority of research regarding attention-deficit/hyperactivity disorder (ADHD) and social support frames questions of communication competence by placing neurodiverse communities at odds with neurotypical ones. This practice reinforces a hierarchy in which neurotypical individuals are viewed as correct and deviations from that norm as failures. Individuals with ADHD experience emotions differently than those without it; thus, it stands to reason that people with ADHD could have different needs and desires for support. Therefore, this study has two key …

The Non-Apprehension Of Selfhood And Metaphysical Freedom, Christopher Rinderle

LSU Master's Theses

In this work I take on one of the most axiomatic assumptions humans possess. The sense of self is embedded so deeply inside each one of us that to question it seems utterly ridiculous. Fortunately, I do not outright reject the notion of selfhood. I investigate what it is and is not through multiple angles – ancient and contemporary – which leads to investigations of free will and responsibility.

In the first chapter, I discuss the Buddhist anātman or non-self. I argue that the historical Buddha did not endorse the idea that the self must be overcome through enlightenment – …

The Influence Of Native Language And Sentence Form On Memory Of Motion Events, Stephanie L. Lopez

LSU Master's Theses

This study utilized four experiments to investigate the extent to which native language influences memory in accordance with linguistic relativity. In Experiment 1, monolingual English speakers and Spanish/English bilinguals were divided into a verbal encoding condition and a verbal suppression encoding condition and watched motion events of low or high physical salience. Participants engaged in a recognition memory task followed by an event memory similarity judgment task. In Experiment 2, native monolingual English speakers were divided into an English-like (or manner-on-verb) description group, a Spanish-like (or path-on-verb) description group, mimicking the language groups of Experiment 1 respectively, and a verbal …

Neurocognitive Models Of Anxious Apprehension And Emotion Regulation: Implications For Working Memory, Paul Spano

LSU Master's Theses

Children and adolescents with internalizing disorders, such as generalized anxiety and major depression, often experience functional impairment across multiple domains that exacerbates psychopathology. Working memory is a cognitive process that has been scrutinized for its ubiquity in daily life, its strong association with academic success, and its susceptibility to interference from internalizing symptoms, such as a depressed mood or anxious apprehension. However, the literature on the relationship between youth internalizing symptoms and working memory span is sparse, and existing research is confounded by a lack of theoretical clarity and, consequently, incomparable procedures. The present study aims to clarify this relationship …

Times Of Crisis: A Comparative Discourse Analysis Of U.S. And Mexican Presidential Rhetoric, Kassandra Gonzalez-Ramos

LSU Master's Theses

Language is a communicative tool that in the possession of politicians holds the power to be persuasive and aggressive, empowering and uniting, or disruptive and dividing. Previous research has relied on numerous methodological approaches to analyze political discourse from different viewpoints to reveal the manner in which politicians as part of political institutions transform and manipulate language. The current investigation performs a critical discourse analysis (CDA) based on the framework developed by Van Dijk (1993,1997) in order to demonstrate the speech act realization in a total of 14 political speeches delivered by American presidents Biden, Trump, and Obama and Mexican …

Watching Sports Online: Evaluating The Viewing Motivations Of Sports Streaming Service Users, Jordan Dove

LSU Master's Theses

With millions of viewers tuning in to sporting events each year, there are many different motivations to analyze as to why there are such a large amount of people involved. More recently, sports streaming services have become a second option for viewers to watch sporting events, creating even more popularity for the sports market. New highs of streaming viewers have been seen with each passing year, as new media continues to take over old traditional media like network television. In 2022, for instance, streaming service viewership surpassed cable tv and broadcasts (Nielsen, 2022), creating a turning of the tide. Many …

Beyond Compulsion: Félix Ravaisson's Conception Of Habit, Christopher Johnson

LSU Master's Theses

In opposition to a tendency present within the history of Western philosophy to regard ‘habit’ as a conservative force (represented by figures including Descartes, Spinoza, and Kant), contemporary philosophers working on habit (including Clare Carlisle and Catherine Malabou) have marshaled the thought of nineteenth century French philosopher Félix Ravaisson. With recourse to the ‘double law of habit,’ Ravaisson, in his 1838 doctoral thesis, depicts habit as both resistance and receptivity to change. I begin, in Chapter One, with a brief overview of the aforementioned negative evaluations of habit, as surveyed separately by Carlisle and Malabou. As these contemporary philosophers observe, …

Cannabis Use Across The Menstrual Cycle: The Impact Of Negative Affect And Coping Motives, Paige Morris

LSU Master's Theses

Women appear to use more cannabis during the premenstrual and menstrual phases of the menstrual cycle, presumably because women use cannabis to manage increases in negative affect associated with these phases. Yet little work has tested this hypothesis or examined individual difference variables associated with greater coping-motivated cannabis use. The current study tested whether state negative affect interacts with coping motives to predict greater cannabis use during the premenstrual and/or menstrual phases and whether trait anxiety or difficulties with emotion regulation moderate these relations. Female undergraduate students with regular monthly menstrual cycles and who were not using hormonal contraceptives ( …

Effects Of Task-Switching On Proactive Control And Metamemory Regulation, Jessica Hacker

LSU Doctoral Dissertations

Past researchers have proposed a relationship between cognitive control and metamemory and several studies have provided the most support for a relationship between task-switching and metamemory regulation. Nevertheless, the evidence has been correlational. To my knowledge, the present study was the first to include an experimental manipulation incorporating a dual-task that required task-switching within a feeling of knowing (FOK) paradigm to directly observe the effects of task-switching on FOK accuracy. Research on cognitive control has demonstrated that engaging in proactive cognitive control typically leads to better performance in cognitive tasks and that young adults are naturally biased to engage in …

Performance Anxiety In Young Musicians: A Case Study Of Music Educators' Experiences, Carmen L. Rodriguez

LSU Doctoral Dissertations

Anxiety is a common emotional reaction in musicians that can negatively influence their performance. Some studies have proved that Music Performance Anxiety (MPA) can be found not only in adults but also in adolescents and children from 3 years old. Since MPA is a significant aspect of musicians’ development, it is essential that music educators take preventive action against MPA in young musicians, specifically under 18 years old. The purpose of this study is to examine the strategies used by music educators to address MPA in young musicians. Educators were interviewed regarding musical performance anxiety and its presence within their …

Identifying Key Language Research Priorities In Autistic Children According To Parents, Taylor Hale

LSU Master's Theses

The lack of involvement of the autistic community and its stakeholders in autism research has led to a call to action. At present, autism researchers have limited knowledge about stakeholders’ priorities for research. The current study aimed to bridge the disconnect between the extant autism research and the recent neurodiversity movement by surveying key stakeholders – parents of autistic children – on their perspectives on autism research that focuses on language. Twenty-six parents of autistic children completed an online survey on their views on autism language research with an option to participate in a follow-up interview. Six parents participated in …
