Experiences Of Transgender Men Who Joined National Pan-Hellenic Council Sororities Pre-Transition, Sydney Epps

LSU Doctoral Dissertations

The National Pan-Hellenic Council (NPHC) - affectionately known as The Divine Nine - are places of support and leadership development for students. However, these groups espouse traditional gender role themes that align with sexual orientation and gender rigidity. This paper explores how four NPHC members negotiate their identity as both nonbinary or transgender, and Greek. Using the narrative inquiry approach, the researcher will explore how sorority members who no longer identify as cisgender women are treated post-gender transition by other sorority members.

Sexually Dimorphic Oxytocin Receptor-Expressing Neurons In The Anteroventral Periventricular Nucleus Regulates Maternal Behavior, Kaustubh Sharma

LSU Doctoral Dissertations

The neurohypophysial hormone oxytocin is involved in the regulation of social behaviors, including social recognition, pair bonding, and sex-specific parental behaviors in a variety of species. Oxytocin triggers these social behaviors by binding to oxytocin receptors (OXTR) in various parts of the brain. Oxytocin-induced sex-typical behavior, therefore, suggests a sexual dimorphic distribution of OXTR in the brain. In recent years, the oxytocin system in the brain received tremendous attention as a potential pharmacological target for treatment of many psychiatric disorders, such as anxiety, autism spectrum disorders, and even sex-specific psychiatric disorder like postpartum depression (PPD). An important problem and a …

Three Essays On Variation In Intergenerational Mobility And Incarceration In The United States, Vikash Dangal

LSU Doctoral Dissertations

The U.S. is often called the “land of opportunity” but there are substantial disparities in the opportunity and life outcomes of children depending on where they grow up. The structural factors that shape future outcomes of children can be traced to their childhood environment. This dissertation builds upon the existing literature on childhood environment and future outcomes of children and presents three essays on the variation in intergenerational income mobility and incarceration in the US.

In the first essay in chapter 2, I employ spatial regime analysis to study how the factors affecting absolute upward mobility vary due to local …

Civil War Interventions: An Examination Of The Roles Of The Media, Political Executives, And The Domestic Opposition, Jonathan Charles Nickens

LSU Doctoral Dissertations

This dissertation examines how media attention and domestic opposition parties affect third-party intervention in foreign civil wars. Previous research defines some of the ways that political executives in democratic states are constrained in their choice of actions, while also pointing out the influences and limitations of outside actors. This dissertation builds on existing research pertaining to opposition parties and the news media by providing new theories on how these outside actors can push a leader in taking an action he otherwise might not take, such as intervening in a foreign civil war. Using newly collected data, I argue that the …

Comparison Of In-Office Psychiatric Encounters With Out-Of-Office Psychiatric Encounters Regarding Efficacy, Presenteeism, And Self-Perceived Stigma Among Adult Recipients Of Psychiatric Treatment For Depression In Louisiana, Lawrence Sullivan Salone

LSU Doctoral Dissertations

The primary purpose of this study was to conduct a clinical trial to compare the provision of psychiatric evaluation and medication interventions in a virtual out of office format (VOO) with the provision of psychiatric evaluation and medication interventions in a virtual in-office psychiatric encounter (VIO) among adults in Louisiana seeking psychiatric services for the treatment of depression. This study was classified as a pretest-posttest control group non-inferiority double-blind experimental design. Each patient took a self-rated instrument at baseline and at week 8. The study tested the two interventions (VOO and VIO) by way of changes in overall function, changes …

Comparison Of High-Tech Augmentative And Alternative Communication Interfaces: Do Age And Technology Experience Matter?, Surani Gopika Nakkawita

LSU Doctoral Dissertations

Previous research has demonstrated that individuals with stroke-induced aphasia can use augmentative and alternative communication (AAC) when they cannot meet their communication needs using spoken language (Dietz, Weissling, Griffith, McKelvey, & Macke, 2014; Purdy & Van Dyke, 2011). Of the various interfaces found in the different AAC systems, the grid display and the visual scene display (VSD) have been used by individuals with aphasia (Hough & Johnson, 2009; Dietz et al., 2018). However, there is a scarcity of research examining the comparative usefulness of these interfaces.

This prospective study attempted to understand how neurologically healthy individuals of different ages and …

Using Spatial Analysis And Machine Learning Techniques To Develop A Comprehensive Highway-Rail Grade Crossing Consolidation Model, Samira Soleimani

LSU Doctoral Dissertations

The safety of highway-railroad grade crossings (HRGC) is still an issue in the United States of America (USA). The grade crossing is where a railroad crosses a road at the same level without any over or underpass. To improve the safety of crossings, the crossings’ condition should be explored from several aspects such as engineering design (speed limit, warning signs, etc.), road condition (number of lanes, surface markings, etc.), rail design (the type of track, ballast, etc.), temporal variables (weather, visibility, time of day, lightning, etc.), social variables (population, race, etc.), and last but not least, spatial variables (the type …

Readiness To Change And Smoking Expectancies Among Adult Male Substance Users Currently In Substance Use Treatment, Aaron French Waters

LSU Doctoral Dissertations

The primary aims of the current study were to examine if smoking expectancies and readiness to quit smoking, important components in predicting smoking behavior and cessation, changed across time for adult smokers in substance use treatment. Participants (N = 51) were predominantly white (96.1%), adult, male smokers who were admitted to residential substance use treatment. Smoking outcome expectancies and readiness to change smoking were assessed among participants at treatment entry (n = 51), and subsequently at 30 days (n = 13), 60 days (n = 9), and 90 days (n = 3) from treatment entry. …

Moderators Of Academic Performance And Symptom Severity In Adolescents With Attention-Deficit/Hyperactivity Disorder, Ryan Nicole Cummins

LSU Doctoral Dissertations

Research has documented the relationship between attention-deficit/hyperactivity disorder (ADHD) symptom severity and poor academic outcomes. However, few studies have focused on identifying moderating variables of academic performance specific to adolescents, especially those with ADHD. The current study seeks to address these limitations, further exploring moderators of academic outcomes in a clinical sample of adolescents with ADHD. Specifically, the present study examined adolescent ratings of routines, parent-adolescent conflict, perceptions of parental involvement, and school engagement, on the relationship between ADHD symptom severity and academic performance (GPA). The sample consisted of a total of 140 caregiver-adolescent dyads ranging from ages 11- to …

Examining Patterns Of Executive Functioning Across Dimensions Of Psychopathology, Scott Roye

LSU Doctoral Dissertations

Executive functioning is a multifaceted collection of higher-order cognitive processes used to perform goal-oriented tasks. Although this construct is heavily researched, a major issue regarding the current literature stems from the influence of task impurity, which interferes with how executive functioning performance is interpreted. Additionally, while executive functioning has been previously explored in clinical populations, less work has evaluated this topic measuring dimensional psychopathology. The present study sought to examine the role of executive functioning, as it relates to dimensional psychopathology. Data was analyzed from a total of 731 individuals between the age of 18-59 years who took part in …

Factor Predicting Maternal Posttraumatic Stress Symptom Trajectories Following A Natural Disaster: Coping, Social Support, And Family Functioning, Jennifer Clare Piscitello

LSU Doctoral Dissertations

Natural disasters are sudden, large-scale events that are associated with significant mental health consequences. Although, most individuals demonstrate resilience, a significant subset of the population develops significant long-term distress (La Greca et al. 2013; Lai, et al., 2015; Lowe & Rhodes 2013; Self-Brown et al., 2014). Moreover, results from emerging longitudinal research suggests that symptom patterns are heterogenous. For example, some individuals recover over time or demonstrate a delayed onset. The most commonly studied post-disaster reaction in adults is posttraumatic stress (PTS) symptoms. However, the extant literature examining elevated PTS symptoms and related risk factors in disaster research has relied …

Protestant Experience And Continuity Of Political Thought In Early America, 1630-1789, Stephen Michael Wolfe

LSU Doctoral Dissertations

The debate on the continuity of American political thought from the 17^th century Puritan settlements to the 18^th century American founding assumes a bipolar spectrum, ranging from strong continuity to strong discontinuity. The degree that scholars recognize distinctively Christian, theological, or Protestant ideas operating in the founding era determines where they are placed on the spectrum. The most popular view today is the “amalgam” thesis, which is a moderate view, resulting from decades of debate. Amalgam theorists argue that the founders' political theory relied on a variety of sources, from classical to Protestant. The current debate centers on …

Generalizability Of Multiple Measures Of Treatment Integrity: Response Card Intervention, Elizabeth Kelsey Wilson

LSU Doctoral Dissertations

Treatment integrity is essential for the implementation of interventions in schools as it determines the accuracy or consistency with which different components of a treatment are implemented. There are no current standards regarding the best practices in treatment integrity measurement; however, higher treatment integrity is associated with enhanced student outcomes. At present, there is no database that provides information related to treatment integrity for practitioners, researchers, and policy-makers to reference when choosing an appropriate level of treatment integrity needed for a given intervention. Consequently, there is a need to establish convergent validity among different methods of treatment integrity measurement using …

Individual Differences In Prospective Memory Aftereffects: The Role Of Working Memory Capacity And Inhibition., Samantha Nicole Spitler

LSU Doctoral Dissertations

This study examined attentional control and executive function (EF) in relation to canceled intentions in two experiments. After an intention is canceled, a commission error occurs when one continues to actively fulfill the intention in response to a prospective memory (PM) cue. Aftereffects are slower response times to inactive PM cues when encountered in ongoing processing. Attentional control was indexed by working memory capacity (WMC) and EF was indexed by three measures of inhibition. In prior canceled intention PM research, attentional control and inhibition have not been extensively studied. However, two major methodological factors in PM research could implicate attentional …

Previous Experiences Drive Attention, Sunghyun Kim

LSU Doctoral Dissertations

Traditionally, the allocation of attention was understood within goal-driven and stimulus-driven factors. However, the traditional approach cannot fully account for the mechanism of attentional orienting. Instead, a growing body of evidence shows that previous search experiences, irrelevant to both goal-driven and stimulus-driven factors, influence attentional allocation. For example, when contexts predict information of targets, the contexts guide attention toward the stimuli having the information predicted by the contexts: contextual cueing. In addition, more valuable stimuli attract more attention: value-driven attentional capture. However, two critical issues are present. First, contextual cueing has been found largely when the contexts and the target …

The Relative Impact Of Risk And Protective Factors On The Psychological Functioning Of Sexual And Gender Minority Youth, Ilayna Krysten Mehrtens

LSU Doctoral Dissertations

Research has consistently indicated that sexual and gender minority (SGM) youth are at increased risk of psychological and emotional concerns relative to their cisgender heterosexual (cis-heterosexual) peers. A large body of research has sought to identify the risk factors that may contribute to this disparity; however, fewer studies have investigated the factors that may promote resiliency, thereby reducing risk. Subsequently, very little is known about the relative influence of risk and protective factors among SGM youth. Additionally, significant methodological concerns have been identified, which may affect the interpretability, generalizability, and clinical applicability of existing research. The purpose of this study …

Southwest Pacific Tropical Cyclone Frequency And Intensity Related To Observed And Modeled Geophysical And Aerosol Variables, Rupsa Bhowmick

LSU Doctoral Dissertations

The dissertation focuses on western region of Southwest Pacific Ocean (SWPO)

basin (135E - 180, and 5S - 35S) tropical cyclone (TC) climatology using observed

and modeled data. The classification-based machine learning approach

identifies the synoptic geophysical and aerosol environment favorable or unfavorable

for TC intensification and intensity change prior to landfall incorporating

observational and satellite data. A multiple poisson regression model with varying

temporal monthly lags was used to build a relationship between the number of

monthly TC days with basin wide average dust aerosol optical depth (AOD), sea

surface temperature (SST), and upper ocean temperature (UOT). This idea …

Components Of Psychological Flexibility And Inflexibility That Predict Risk-Taking Behaviors, Shelley Renee Upton

LSU Doctoral Dissertations

Psychological flexibility is conceptualized as contact with the present moment and the ability to persist or change one’s behavior to achieve valued ends. The opposite of this process is known as psychological inflexibility, which is posited to lead to the development and maintenance of various psychological disorders. There are 6 components underlying psychological inflexibility—these are cognitive fusion, experiential avoidance, fixating on the past or future, self-conceptualization, lacking contact with values, and inaction toward valued ends, as well as 6 components underlying psychological flexibility (i.e., defusion, acceptance, present moment awareness, self-as-context, contact with values, and committed action). Psychological inflexibility may be …

Social Capitalization As A Positive Emotion Regulation Strategy In Individuals At-Risk For Developing A Schizophrenia-Spectrum Disorder, Elana Klein Schwartz

LSU Doctoral Dissertations

Extant literature indicates that emotional deficits, such as impaired emotion expression/experience, are prominent in schizophrenia-spectrum psychopathology and linked with poorer functional (e.g. social) outcomes. Interestingly, individuals exhibiting schizotypy, an underlying personality organization that confers a vulnerability to developing schizophrenia, report more abnormalities in emotion experience compared to healthy controls and individuals with schizophrenia, a phenomenon termed the “schizophrenia-spectrum emotion paradox.” To aid in the clarification of emotional abnormalities and explore the dynamic nature of emotion experience in individuals with schizotypy, the present study enrolled 93 college-aged individuals to examine positive emotion regulation through the use of social capitalization. In social …

The Role Of An Educational Intervention In Addressing Parent Spectator Behaviors In Louisiana Youth Sports, Jerry F. Reynolds Ii

LSU Doctoral Dissertations

Contemporary youth sports environments present significant psychosocial challenges to the family system. Among the greatest challenges to address are spectator behaviors of parents, which in the public eye has deteriorated and is out of control. Spectator behaviors and their impact upon the sports environment and family system is the topic of investigation in this study. Within the state of Louisiana, the advent of Act 355 extends the consequences of parent behavior and presents challenges to families, referees, and sports organizations. To better understand how legislation impacts parent perceptions of their spectator behaviors, the author examined spectator behaviors parents are observing, …

A Component Analysis Of Implementation Planning: Examining Mechanisms That Underlie A Teacher Implementation Support Strategy, James Jaran Upright

LSU Doctoral Dissertations

To maximize instructional time, teachers must be able to effectively manage student behavior. However, surveys consistently reveal that a significant portion of teachers feel underprepared to address challenging classroom behavior. One of the most effective ways to reduce problem behaviors in school is with systematic classroom management strategies, such as the good behavior game. However, teachers often struggle to effectively implement such procedures. Promising evidence has emerged for implementation planning as an effective support strategy to improve teachers’ intervention implementation. Implementation planning is a one-time consultation process for intervention procedure planning (action planning) and identification and resolution of implementation barriers …

Agenda Cueing In Aggregated Newsfeeds, Kirill Bryanov

LSU Doctoral Dissertations

This dissertation brings together the findings from three experimental studies that seek to understand how exposure to information in an online news aggregating portal can influence users’ perceptions of the relative importance of problems facing society. Theoretically, this investigation relies on two foundational ideas. One is that in today’s high-choice, multi-source media environment communication flows are curated by a variety of gatekeeping actors, such as algorithms and fellow users. Individuals can have varying attitudes toward and perceptions of these gatekeepers, which can influence the effects of exposure to online information, including agenda-setting outcomes. Another is that users of digital news, …

An Investigation Of Athletic Buoyancy In Adult Recreational And Sport Club Athletes, Jackie Rae Victoriano Calhoun

LSU Doctoral Dissertations

Athletic buoyancy is the ability of an athlete to effectively handle the daily setbacks and challenges they face during training and competition. Although buoyancy has received ample research in the academic domain, a dearth of information exists regarding buoyancy in the athletic domain. Therefore, the overall purpose of this dissertation was to investigate athletic buoyancy’s independent contribution to sport psychology while also exploring antecedents and outcomes in adult athletes.

Study 1 compared athletic buoyancy to other cognate constructs, or similar constructs, to determine their conceptual boundaries. A one-time, online questionnaire was distributed to 294 recreational athletes (M age = …

Video-Based Interventions: Teaching Adults And Preschoolers, Philip Ross Richard Iii

LSU Doctoral Dissertations

Long gone are the days in which technology is looked upon as a trivial novelty. Whether evoking positive or negative reactions, advancements in technology continue to alter our daily environments. One such example is Video Based Interventions (VBI). VBI utilize video recording to facilitate the acquisition of various skills and behaviors (Rayner, Denholm, & Sigafoos, 2009). While it may sound like a simple intervention at first, many procedural variations of have been examined in research and practice. The two experiments comprising the current study examined the effectiveness of video models when used in conjunction with other instructional methods. Experiment I …

Examining Relationships Between Early Childcare Teachers' Adult Attachment Orientations And Quality Of Interaction In The Infant Classroom, Alexandra Morris Benoit

LSU Doctoral Dissertations

Over the past several decades, women have entered the workforce in increasing numbers. This has led to the majority of infants and young children being cared for outside of the home by extra-familial caregivers. Research has shown the benefits that quality childcare can have on the developmental trajectories of children, as well as the detrimental effects that can be seen when children experience low quality care. Further, children are particularly vulnerable in the first year of life when they are establishing attachment bonds with their primary caregivers. With the long hours that many spend in the care of childcare workers, …

LSU Doctoral Dissertations

This critical performance ethnography presents the theory, methodology, and practice surrounding the fieldwork, scripting, and performance of Baton Rouge SLAM!: An Obituary for Summer 2016. As participant-observer, director, and co-performer, I unpack social drama, performance ethnography, and slam culture by employing a lens rooted in critical race theory. Local poets permitted me to de- and re-contextualize their interviews into ensemble scenes and theatricalize their slam poems about the recent summer’s charged events. One year later, this involved and embodied process of ethnographic bricolage became the ensemble cast performance of Baton Rouge SLAM!: An Obituary for Summer 2016. Community members and …

Analyzing Climate Risk To Maritime Cypress Swamps And Pine Savannas Of The Gulf Of Mexico Coastal Plain, Clay Stephens Tucker

LSU Doctoral Dissertations

As sea levels rise, coastal trees are increasingly stressed by saltwater inundation, and stressed trees are ideal for studying changes in the environment through time. Dendrochronology has been used for more than a century to explain changes in past environments using tree rings. Using ring widths and stable isotopes from coastal trees, the effects of tropical cyclones and freshwater moisture availability are shown in regard to tree growth and ultimately are discussed in terms of change to the environment as a whole. Changes in tree growth as they relate to various climate parameters are measured using superposed epoch analysis, moving-window …

Family Matters. Or Does It? Family Involvement In American Education, Isaiah Fink Avraham Cohen

LSU Doctoral Dissertations

“Family Matters. Or Does It?” uses select data and waves from the 1996-2016 Parents and Family Involvement in Education Surveys to investigate the following research questions in its efforts to probe the influence of familial involvement: (1) Does child behavior influence family involvement; (2) has the effect of family involvement on academic performance persisted over the past two decades; (3) does school selection influence family involvement; and (4) are homeschooling families monolithic in their involvement? Results indicate that behavior has unique associations with involvement, with no support being found for the reactive involvement hypothesis. Family involvement has a generally positive …

Understanding The Impact Of Psychological Empowerment, Workplace Motivation, And Social Capital On The Job Performance Of Farmers In Honduras: A Mixed Methods Study, Susan Lale Karimiha

LSU Doctoral Dissertations

A farmer’s job performance is critical to the production of raw materials such as food, fiber, and fuel and is therefore an important concern for individuals, businesses, and economies across the world. The literature on improving farmers’ job performance has focused more on introducing new technologies, and less on the psychosocial factors that improve job performance. The primary purpose of this study was to examine the impact of psychological empowerment, workplace motivation, and social capital on farmers’ job performance in Honduras.

A mixed methods approach was used to collect and analyze both quantitative and qualitative data. For quantitative data, a …
