The Impact Of Experimentally-Induced Perceived Discrimination On Substance Use, Kimberlye Elise Dean

LSU Doctoral Dissertations

Substance use disorders (SUDs) are among the most debilitating psychiatric disorders. Although prevalence rates of SUDs are similar between White and Black adults, these groups experience differential treatment outcomes (e.g., Black adults with SUDs are more likely to report greater pre- and post-treatment substance use). Examining culture-specific correlates of racial differences in substance use is vital to improve understanding of the etiological and maintaining mechanisms of SUDs among Black adults. Perceived racial discrimination (PRD) is prospectively related to various substance use-related outcomes. Thus, some may use substances to alleviate psychological distress (e.g., anxiety) associated with PRD, which may over time …

Factors Influencing Retirement Decision Making For Louisiana State Government Employees, Osama A. Amous

LSU Doctoral Dissertations

ABSTRACT

Public pension members continually face factors affecting their decision to retire in the changing American society. Workers are living longer and need more medical care with better retirement benefits. For Louisiana public employees specifically, no prior studies have examined the factors affecting workers’ decision to retire nor evaluated the factors impacting workers’ decision.

This multiphase study aimed to identify factors and evaluate the decision-making process that enables Louisianans to retire happily and satisfied with a guaranteed income, and to examine millennials’ decision-making process. In the initial phase, ten active and retired male and female participants answered questions in-person, leading …

Validation Of The Dual-Factor Model Of Mental Health In College Students: An Investigation Of Group Characteristics, Ashley Perle Galsky

LSU Doctoral Dissertations

The dual-factor model of mental health proposes that symptoms of mental illness and markers of mental wellness can occur simultaneously, while functioning as discrete factors that contribute to mental health and adaptive functioning (Keyes, 2005). The current study investigated the utility of the dual-factor model of mental health (cf. Greenspoon & Saklofske, 2001; Suldo & Shaffer, 2008; Suldo, Thalji, & Ferron, 2011) in college students (N = 1,023). Using self-reported symptoms of depression, anxiety, stress, inattention, and hyperactivity/impulsivity as indicators of psychopathology, in combination with self-reported subjective well-being (SWB) as an indicator of wellness, participants were classified into one …

The Influence Of Selected Factors Impacting The Incidence And Severity Of Accidents Involving Pedestrian/Bicyclists And Motorized Vehicles In Urban Areas Of Louisiana, Randall M. Verret Jr.

LSU Doctoral Dissertations

The primary purpose of this study was to determine the influence of selected demographic, environmental and infrastructure factors on the incidence and severity of traffic accidents involving a motorized vehicle and a non-motorized (pedestrian or bicyclist) individual. Identification of influential factors can aid in developing more effective countermeasures, targeted education and training programs to reduce the fatality and injury risks to vulnerable road users. A total of 9,538 crash data records involving vulnerable road users and motor vehicle drivers were utilized in this study.

Overall, vulnerable road users were found to have higher incidences of impairment than motorized vehicle drivers …

A Longitudinal Study Of Two Teacher-Report Screening Measures For Student Mental Health: Comparing The Swtrs And Saebrs, Anthony Joseph Roberson

LSU Doctoral Dissertations

This study compared the comparative utility of two teacher-report universal screeners for student mental health, the Student Wellbeing Teacher-Report Scale (SWTRS) and the Social, Academic, and Emotional Behavior Risk Screener (SAEBRS), across two occasions during the school year. Both instruments measure aspects of academic, social, and emotional student behavior from the teacher’s perspective but differ in their inclusion of both positive and challenging behaviors (i.e., SAEBRS) or positive behaviors only (i.e., SWTRS). Results suggest that both have strong concurrent and predictive validity characteristics in identifying student risk but differ in which outcomes they are better at predicting.

Social Determinants Of Health Inequality: Predictors Of Hiv Transmission Among African Americans In The Deep South, Kayla Allison

LSU Doctoral Dissertations

HIV/AIDS has become an epidemic in Black communities in the Deep South, which poses a major public health crisis. Unfortunately, the lack of attention from health officials has resulted in African Americans experiencing the greatest burden of the disease as compared to any other racial/ethnic group. Thus, this cross-sectional, correlational study examined predictors of HIV transmission with an emphasis on the course of the disease among African Americans in the Deep South region of the United States given the legacy of slavery, historical racism, and plight of African Americans in this geographical area. The institution of slavery was not isolated …

Derivational Development: Derivational Word Processing In Three English-Speaking Populations, Lisa Suzanne Kemp

LSU Doctoral Dissertations

Native-English speaking adults use morphological decomposition to understand complex words (e.g. farmer becomes farm-er). Whether decomposition is driven by semantic organization is still unclear. It is also unclear whether ESL adults and elementary age children use the same word processing strategies as native speaking adults. This study tested an identical experimental procedure across three English-speaking populations: native speaking adults, non-native speaking adults and elementary age children. The first task tested how readers use base and suffix information in complex words and nonwords when the word featured only a base word, only a suffix, both a base and …

Addressing Racial Disparities In Parent Training Enrollment: An Examination Of Help-Seeking For Child Behavior Problems Among African American Mothers, Kasia Plessy

LSU Doctoral Dissertations

The consideration of African American mothers’ mental health help-seeking attitudes and intentionsis important when developing culturally sensitive parent training programs and potentially help bridge a critical knowledge and service gap for this population. The purpose of this study is to examine the parental help-seeking for child externalizing behavior problems in order to delineate variables that might influence BPT enrollment among African American families. To address the lack of research considering cultural factors, this study examines the influence of racial group identification, cultural childrearing values, and mental health stigmatization on African American mothers’ problem recognition and willingness to engage in behavioral …

Deciphering Public Transit Ridership In Baton Rouge: Spatial Disaggregation Approaches, Xuan Kuai

LSU Doctoral Dissertations

Background: Surveys across the U.S. reveal that commuters driving personal vehicles spend a significant amount of time in traffic, while public transit, as an efficient commuting mode, has been largely underutilized.

Purpose: What causes a low public transit ridership? How could public transit ridership be explained by demographic, socio-economic and spatial characteristics of neighborhood? This study answers these questions by deciphering the relationships between public transit ridership and various factors in a medium-size city in southern U.S. – Baton Rouge, Louisiana.

Methods: Non-spatial and spatial data in a larger areal unit (e.g., block group) are used to infer demographic, socio-economic …

The Importance Of Landscape Position Information And Elevation Uncertainty For Barrier Island Habitat Mapping And Modeling, Nicholas Matthew Enwright

LSU Doctoral Dissertations

Barrier islands provide important ecosystem services, including storm protection and erosion control to the mainland, habitat for fish and wildlife, and tourism. As a result, natural resource managers are concerned with monitoring changes to these islands and modeling future states of these environments. Landscape position, such as elevation and distance from shore, influences habitat coverage on barrier islands by regulating exposure to abiotic factors, including waves, tides, and salt spray. Geographers commonly use aerial topographic lidar data for extracting landscape position information. However, researchers rarely consider lidar elevation uncertainty when using automated processes for extracting elevation-dependent habitats from lidar data. …

Examining The Mechanisms Of Religious Ecology On Population Health And Material Well-Being, Joseph Andrew Clark

LSU Doctoral Dissertations

A growing body of research has addressed the relationship between community-level religious environments and important aspects of well-being, such as mortality, crime, and social mobility. This research argues that the prevalence of specific religious traditions shapes these important outcomes through a variety of mechanisms. While there is no shortage of mechanisms proposed by authors - such as local attitudes towards public institutions, gender norms, and social networks - these mechanisms remain themselves untested. A notable critique of this literature suggests that without evidence supporting the existence of these mechanisms as described, scholars involved in this research run the risk of …

Attention As A Mechanism For Object-Object Binding In Complex Scenes, Kacie Mennie

LSU Doctoral Dissertations

The current study attempted to determine whether direct binding between objects in complex scenes occurs as a function of directed attention at encoding. In Experiment 1, participants viewed objects in one of these different types contexts: unique scenes, similar scenes, or arrays with no contextual information. Critically, only half of the objects were attended for each encoding trial. Participants then completed an associative recognition task on pairs of items created from the previously studied scenes. Test pairs consisted of two attended or unattended objects, and were associated with a unique scene, a similar scene, or an array. Evidence of binding …

Examining The Evolution Of Urban Multipurpose Facilities: Applying The Ideal-Type To The Facilities Of The National Hockey League And National Basketball Association, Benjamin Downs

LSU Doctoral Dissertations

The standardized versions of ice hockey and basketball emerged during the last quarter of the 19^thcentury. In short order both ice hockey and basketball evolved from amateur, recreational activities to professional sport and entertainment businesses. This study analyzes, contextualizes, and discusses the layout of the urban multipurpose facilities that emerged to house both professional hockey and professional basketball, with particular attention paid to the facilities of the National Hockey League and National Basketball Association. The study uses the lens of modernization and the ideal-type heuristic device to extend Bale’s and Seifried’s facility evolution models. In addition to providing …

Thelonious Monk's Prototypical Style: Close And Distant Readings Of Jazz Stylings, Connor Davis

LSU Doctoral Dissertations

Thelonious Monk’s style has been considered non-conformist, modernist, technically stilted, intentionally unconventional, even incompetent. His performing is idiosyncratic, to say the least. However, by what metric is his performing idiosyncratic, or, framed another way, in what ways do Thelonious Monk’s performances deviate from the prototypical performance? Situated within family resemblance theories of prototypicality, I utilize supervised and unsupervised machine learning approaches to categorize jazz solos based on their melodic usage of standard jazz language (novel corpus of 530 jazz solo improvisations). Using these distant readings to determine which solos are prototypical, I perform a close reading of these prototypical solos …

The Rise And Fall Of Focused Deterrence Initiatives, Chandra Lynore Joseph

LSU Doctoral Dissertations

Following the national uptick of violence across the country, societal angst has once again begun to surface. Those in positions of authority began to look to the criminal justice system for ways to address this cyclical issue. Traditionally, applying law enforcement crackdowns and increased penalties and sanctions to the offenders were the main topics of discussion. However, over the last two decades, problem-oriented policing has begun to emerge. Problem-oriented policing works to identify why things are going wrong and to frame responses using a wide variety of often untraditional approaches (Goldstein 1979). One of the problem-oriented frameworks known as the …

Developmental Regression In Children With Autism Spectrum Disorder: Associated Factors And Outcomes, Jasper Abarte Estabillo

LSU Doctoral Dissertations

Autism spectrum disorder (ASD) is an increasingly common neurodevelopmental disorder characterized by deficits in socialization skills and the presence of restricted and repetitive behaviors. In addition to a number of medical and psychological comorbidities, ASD is associated with a complex phenomenon: developmental regression (i.e., loss of skills in developmental domains). Although present in other disorders (albeit rare), developmental regression is prevalent among individuals with ASD. Thus, interest in studying the phenomenon has grown. However, research on associated risk factors and outcomes is limited and findings have been inconsistent. The current study had two aims: (1) examine potential factors associated with …

Can Cooler Heads Prevail? New Media Technology And Affective Polarization, Brian Kendall Watson

LSU Doctoral Dissertations

Are new media technologies stirring up negative partisan feelings in the American public? Can researchers find ways of using new media tools to reduce affective polarization? Relying on a series of experiments featuring online newsfeeds and social media discussions, this dissertation seeks to answer these questions by testing the influence of partisan news and political discussions in realistic Internet environments. Two custom news “portals” (2016, 2018) expose participants to actual partisan news content. Two Facebook discussion experiments (2017, 2019) randomly assign participants to start real political discussions on their personal social media accounts, using discussion-initiation strategies designed to reduce partisan …

The Religious Impact: Understanding The Influence Of Religiosity On Attitudes Toward Policy Issues, Angela Farizo Mccarthy

LSU Doctoral Dissertations

The purpose of this dissertation is to shed light on the influence of religion on Americans’ attitudes toward policy concerns. How do denominational affiliation, religious participation, and religious beliefs influence one’s views on social and/or economic policies? I consider the impact of religious belonging, religious behaving, and religious believing—also known as the “3B’s” – on public opinion toward contemporary issues in the United States. In this comprehensive analysis, I discover the importance of including the religious dimensions in models of public policy attitudes. The first part of this project is to outline the current state of the literature and present …

An Examination Of The Effects Of Post-Identification Feedback On Jurors, Daniella Cash

LSU Doctoral Dissertations

Post-identification feedback (PIF) occurs when witnesses are given feedback following their identification choices. This feedback has been shown to alter witnesses’ retrospective judgments regarding their witnessing experience (e.g., they are more confident that they made a correct identification). PIF effects are robust; they impact witnesses’ memory of their experience, and also appear to act as confirmation to jurors who are asked to assess witness reliability. A current recommendation for eyewitness procedures is that identifications should be recorded and shown to jurors at trial, but this might be harmful if jurors are also negatively impacted by this suggestive feedback. The goal …

Empathic Responsivity And Callous-Unemotional Traits Across Development, Julia Elizabeth Clark

LSU Doctoral Dissertations

Callous-unemotional (CU) traits are associated with deficits in empathy and emotional responses to others. Specifically, CU traits are consistently correlated with under-reactivity to others’ distress cues. However, it is unknown whether CU traits are also associated with more general deficits in emotional reactivity (e.g., to situations involving threat to the self). Further, the relationship between CU traits and the ability to accurately identify others’ emotions is not well established, and prior work often has not considered possible developmental changes in this relationship. To address these questions, the current study recruited a school-based community sample of children from kindergarten, third, and …

Aging In The Workplace: A Cross Case Analysis In Jamaica's Finance Sector, Malaika Tahirah Edwards

LSU Doctoral Dissertations

Along with the increase in the number of older people globally, is an increase in the number of older people in the labor force. Older adults increasingly represent a large segment of the working population. The purpose of this study was therefore to explore workplace aging, with specific reference to Jamaica’s finance sector, in relation to organizational preparedness for the aging workforce.

This study examined aging from an organizational perspective, a national perspective, and an individual perspective, through the lens of Baby Boomers. The study was framed through the lens of the Four Frames Model, and the Metaperspectives Theory, which …

Examining Two Self-Assessment Measures Of Teacher Multicultural Competence And Their Predictive Value To Student Behavior Outcomes, Melissa Jo Hamilton Grisdale

LSU Doctoral Dissertations

Multicultural competence is a construct that has been discussed in the education literature as an essential skill for teachers' success in reaching all children in the classroom. The current study advances the literature on multicultural competence, specifically pertaining to teachers within their classrooms. Additional evidence was found building upon the technical adequacy of two, theoretically different, measures of teacher multicultural competence. Teachers who received a greater number of hours of multicultural training had significantly higher self-efficacy regarding engaging in culturally responsive teaching practices, than those who had received fewer hours. This study also replicated previous research (Hamilton, 2016) finding that …

Mapping Soil Moisture From Remotely Sensed And In-Situ Data With Statistical Methods, Yaping Xu

LSU Doctoral Dissertations

Soil moisture is an important factor for accurate prediction of agricultural productivity and rainfall runoff with hydrological models. Remote sensing satellites such as Soil Moisture Active Passive (SMAP) offer synoptic views of soil moisture distribution at a regional-to-global scale. To use the soil moisture product from these satellites, however, requires a downscaling of the data from an usually large instantaneous field of view (i.e. 36 km) to the watershed analysis scales ranging from 30 m to 1 km. In addition, validation of the soil moisture products using the ground station observations without an upscaling treatment would lead to cross-level fallacy. …

Modeling Melodic Dictation, David John Baker

LSU Doctoral Dissertations

Melodic dictation is a cognitively demanding process that requires students to hear a melody, then without any access to an external reference, transcribe the melody within a limited time frame. Despite its ubiquity in curricula within School of Music settings, exactly how an individual learns a melody is not well understood. This dissertation aims to fill the gap in the literature between aural skills practitioners and music psychologists in order to reach conclusions that can be applied systematically in pedagogical contexts. In order to do this, I synthesize literature from music theory, music psychology, and music education in order to …

Examining Successful Aging And Resilience After Disasters, Katie Elizabeth Stanko

LSU Doctoral Dissertations

Resilience, a psychological adaptive process and outcome, is the ability to return to normal functioning after a traumatic event, such as a natural disaster. Successful aging entails biological, psychological, and social factors. The Great Flood of 2016 in the greater Baton Rouge area caused catastrophic structural damage to thousands of homes and businesses. Some of these individuals had previously moved to the Baton Rouge area after receiving catastrophic damage during Hurricane Katrina in 2005. In this study, I investigated the role that age group (younger, middle-aged, older) and disaster exposure group (control, single exposure, double exposure) had on post-disaster well-being. …

Cruzando Para El Otro Lado: Motivation, Communication, And The Migrant Experience, Crystal Paul

LSU Doctoral Dissertations

Latino/a migration scholarship has largely focused on the motivations to migrate and the assimilation of men migrants. When gender is considered in migration research, it is often treated as a demographic characteristic used to track differences in trends between men and women migrants rather than as a structuring entity informing the migration experience. Recent feminist scholars have shifted focus, employing gender as a theoretical tool to understand how gender shapes the migrant experience before, during and after migration. My research draws upon this theoretical approach and uses data collected via in-depth interviews in an attempt to understand how gender shapes …

Political Parties For Protection And Profit: Explaining Opposition Party Competition Under Electoral Authoritarianism, Michael David Toje

LSU Doctoral Dissertations

Despite the presence of open elections and contestable political offices, opposition parties in electoral authoritarian regimes face barriers – formal and informal – that prevent them from attaining de facto power. Yet, these parties still decide to spend the time, money, and effort to run candidates in unfair elections. This dissertation seeks to uncover the reasons that opposition parties decide to compete in such an uncompetitive environment, and what sustains opposition parties though cycles of defeat. It proposes that opposition parties compete not for the purposes of unseating the ruling party, but rather for controlling their own local affairs away …

Forget Me Not: Are Stronger Memories More Susceptible To Retrieval-Induced Forgetting?, Laura Lee Heisick

LSU Doctoral Dissertations

Successfully retrieving information sometimes causes forgetting of related, but unpracticed, information, termed retrieval-induced forgetting (RIF). One explanatory mechanism of RIF suggests related, but currently irrelevant, information is inhibited during retrieval, resulting in poorer memory for competing representations. Critically, this perspective suggests stronger memories are more susceptible to RIF because stronger representations produce additional competition when unpracticed. To resolve this competition, strong competing items are inhibited, resulting in the counterintuitive prediction that stronger memories are more likely to be forgotten. The aim of the current experiments was to replicate and extend recent work suggesting non-typical objects and own-race faces, both of …

The Use Of Geospatial Modeling And Novel Diagnostics To Detect And Map Risk Factors Of Soil-Transmitted Helminths In Feira De Santana, Brazil, Ryan Harry Avery

LSU Doctoral Dissertations

Soil-transmitted helminth (STH) infections impact billions of people worldwide. The traditional STH control approach is a morbidity control strategy implementing mass drug administration (MDA) programs targeting school-aged children (SAC). In Brazil, this control strategy has decreased STH prevalence to less than 20% in most of the country and providing an opportunity to transition from the morbidity control program and towards a surveillance and response system geared towards STH elimination. Surveillance and response systems geared towards elimination require the implementation higher accuracy diagnostics to detect infection in low-transmission communities, surveillance of entire households, high-resolution modeling at the household-habitat scale, and targeted …

Effects Of U.S. Financial Regulations On Labor Markets, Anindo U. Sarker

LSU Doctoral Dissertations

This thesis is based on a collection of three essays which study the effects of financial policy on labor markets. The first two essays investigate the effects of U.S. bank branching deregulation on labor markets. The first essay studies how these regulations impacted wages and working hours of traditional payroll workers. The second essay studies the impact of these policy reforms on the occupational choice to engage in self-employed work. The main finding of this set of studies is credit access has real effects on the workforce. Estimates from the econometric analysis used in this study suggest that credit access …
