Single Or Dual Resources: The Role Of Working Memory In Syntactic Processing, Rebecca Ann Horn
Single Or Dual Resources: The Role Of Working Memory In Syntactic Processing, Rebecca Ann Horn
LSU Doctoral Dissertations
Within the field of psycholinguistics there are those who argue for a close relationship between working memory capacity (WMC) and syntactic processing (Just and Carpenter, 1992) and those who argue that there is no such relationship (Waters and Caplan, 1996b; 2004). Despite years of research, empirical data has yet to settle this disagreement, perhaps because a number of methodological differences between studies from each side make direct comparisons of data nearly impossible. The current study was designed to partially replicate three previous studies using their own experimental sentence types in a self-paced word-by-word reading paradigm in order to examine the …
Functional Interplay Between Neurocognitive Decline And Risk Factors In Older Adults: A Multivariate Latent Growth Curve Model Of Risk, Rebecca Kathryn Macaulay
Functional Interplay Between Neurocognitive Decline And Risk Factors In Older Adults: A Multivariate Latent Growth Curve Model Of Risk, Rebecca Kathryn Macaulay
LSU Doctoral Dissertations
Alzheimer’s disease (AD) is a heterogeneous brain disease with multiple interacting risk factors, suggesting equifinality. Research indicates that the pathophysiological processes involved in AD are evident years prior to disease onset with significant variability in neurocognitive functioning being apparent during preclinical stages. Identification of individuals in preclinical stages is vital, as earlier interventions may prove more effective at ameliorating AD’s devastating effects. In this respect, clarifying relationships between risk factors and neurocognitive functioning in cognitively intact older adults can improve our understanding of mechanisms involved in preclinical AD, which may allow for earlier detection and intervention. The present study employed …
The Baby And Infant Screen For Children With Autism Traits: A Dsm-5 Update, Matthew Jason Konst
The Baby And Infant Screen For Children With Autism Traits: A Dsm-5 Update, Matthew Jason Konst
LSU Doctoral Dissertations
Interest surrounding the investigation of autism spectrum disorder (ASD) has increased exponentially since it was initially described over a half-century ago. With this passage of time our conceptualization of the ASD diagnosis has undergone multiple changes. An increasing trend in research has been an emphasis on early identification and intervention. This trend has brought about the creation and adaptation of multiple measures designed to inform early ASD diagnosis. Recently, the ASD diagnostic category underwent significant revisions. In response to revisions, it is necessary to adapt preexisting measures to reflect these significant changes in order to maintain diagnostic accuracy. The Baby …
Utilization Of The Alabama Parenting Questionnaire Across Family Structures: Do The Same Constructs Apply?, Leah Michelle Adams
Utilization Of The Alabama Parenting Questionnaire Across Family Structures: Do The Same Constructs Apply?, Leah Michelle Adams
LSU Doctoral Dissertations
America has experienced a marked increase in non-nuclear family structures over the last five decades. The evolution of more diverse family systems has led some researchers to eschew a “one size fits all” approach to parenting assessment, as these measures may neglect or misconstrue parent-child dynamics unique to non-nuclear families. The current study examined the underlying factor structure of the Alabama Parenting Questionnaire (APQ) in two distinct family structures to determine if parenting constructs were replicated across groups. Participants included 246 mothers from single parent and two-parent households in Louisiana. Statistical analyses included exploratory factor analysis, replication analysis, hierarchical regression …
Why Interpersonal Ties Are Important For People: An Analysis Of The Concept Of Social Capital And Its Dimensions Of Holism, Convertibility, And Conductibility, Durmus Ali Yuksek
Why Interpersonal Ties Are Important For People: An Analysis Of The Concept Of Social Capital And Its Dimensions Of Holism, Convertibility, And Conductibility, Durmus Ali Yuksek
LSU Doctoral Dissertations
During recent years, social capital has become one of the most widely used concepts in sociological literature, and its popularity has shown itself in both sociological theory and everyday language. Its increasing popularity has mainly resulted from its conceptualizations by some of the most prominent social scientists, such as Pierre Bourdieu, James Coleman, Nan Lin, and Robert Putnam and from its empirical applications to social problems and society afterwards. While many scholars have seen social capital as something of a cure for social problems and perceived social capital theories adequate as they are for their empirical applications, few scholars have …
Liberty, Community, And The Free Man In Magna Carta, Benjamin L. Mabry
Liberty, Community, And The Free Man In Magna Carta, Benjamin L. Mabry
LSU Doctoral Dissertations
This dissertation is an overview of the concept of liberty and community in Magna Carta. The central point is the ethical understanding of liberty which Salisbury calls the habitus of liberty. Liberty is an ethical condition of the individual which exists in tension and parallel to the social status of Liber Homo. This dual characterization of liberty is the causal factor behind the understanding of Magna Carta as both document and event in constitutional history in the related History literature on this topic. Because Liberty is understood in Magna Carta as a habitus, the particular behaviors associated with liberty, referred …
Essays In Labor Economics, Sukriye Elif Filiz
Essays In Labor Economics, Sukriye Elif Filiz
LSU Doctoral Dissertations
In this dissertation, I present three distinct topics on labor economics that can be read independently from one another. In the first chapter, using matched mother-child data from the National Longitudinal Survey of Youth, I investigate the impact of mothers’ involuntary job loss on children’s academic achievement. In the next chapter, I examine the impact of eye and hair color on wages-at-first-job after schooling. In addition, I investigate whether hair color has an impact on the wage-at-the-first-job if the individual resides among people who have similar features. In the last chapter, I examine the impact of unemployment insurance benefit generosity …
A Bayesian Approach To Small Area Estimation Of Health Insurance Coverage, Zhengjia Sun
A Bayesian Approach To Small Area Estimation Of Health Insurance Coverage, Zhengjia Sun
LSU Doctoral Dissertations
Small area estimation focuses on borrowing strength across area in order to develop a reliable estimator when the auxiliary information is available. The traditional methods for small area estimation borrow strength through linear models that provide links to related areas, which may not be appropriate for some survey data. We examine the empirical best unbiased linear prediction method and hierarchical Bayes method with the Louisiana Health Insurance Survey (LHIS), and a hierarchical Bayes method with probit model to fit the LHIS data by using the single year data in 2013. This approach results in a lower level of posterior standard …
Excavations And Interpretation Of Two Ancient Maya Salt-Work Mounds, Paynes Creek National Park, Toledo District, Belize, Rachel Mariah Watson
Excavations And Interpretation Of Two Ancient Maya Salt-Work Mounds, Paynes Creek National Park, Toledo District, Belize, Rachel Mariah Watson
LSU Doctoral Dissertations
In 2012, excavations were conducted at Witz Nabb’ and Killer Bee the last remaining above sea level features Paynes Creek National Park, Belize. Salt is a basic biological necessity that was in limited supply at inland Maya cities. The ancient Maya of coastal Belize produced by fire enhanced evaporation of salt enriched brine. Survey and excavation at inundated salt works in a shallow lagoon in Paynes Creek National Park provide extensive evidence of this technique in the form of briquetage, the remains of pots used in the fire evaporation. Lacking is any evidence that the salinity of seawater was enriched …
Investigations Into Ecogeomorphodynamics Of Coastal Embryo Dunes At Padre Island National Seashore, Texas, Katherine Anne Renken
Investigations Into Ecogeomorphodynamics Of Coastal Embryo Dunes At Padre Island National Seashore, Texas, Katherine Anne Renken
LSU Doctoral Dissertations
This dissertation is an investigation into the interplay between vegetation and aeolian processes in the coastal embryo dune environment at Padre Island National Seashore, Texas. Vegetation is a geomorphic agent, altering aeolian process dynamics. This research adopted a three-pronged approach to improving our understanding of ecogeomorphodynamics in the coastal environment. The first study analyzed large-scale spatiotemporal trends in the vegetation community of the embryo dune environment in order to contextualize smaller scale aeolian processes. Results of this study demonstrated that there was a clear transition in community assemblage from the seaward edge of the embryo dune zone, where species functioned …
Essays On Sub-National Economic Growth: Evidence From A Global Sample, Dachao Ruan
Essays On Sub-National Economic Growth: Evidence From A Global Sample, Dachao Ruan
LSU Doctoral Dissertations
In this dissertation, I make three important contributions to the literature on regional economics. In Chapter 2, I construct a measure of early development, urban population density (urban population relative to total land area), that is novel to the growth literature, and apply GIS techniques to define and locate regions/cities and obtain geographic and historical measures across regions and cities. Chapter 3 investigates the persistence in sub-national development over the past 150 years. I find that regions that had a relatively higher urban population density in 1850 tend to be relatively more developed today. Geographic and climatic characteristics are significantly …
Rhetoric And Food: The Rise Of The Food Truck Movement, Bryan W. Moe
Rhetoric And Food: The Rise Of The Food Truck Movement, Bryan W. Moe
LSU Doctoral Dissertations
This analysis is an attempt to study the rise of a new mobile food medium the food truck. I examine the movement of rhetorical actors, the situation, the audiences, and discourses created and sustained through rhetorical practices. These include looking into contemporary controversies, the history and storytelling that helps to convey identity, a new aesthetic experience created by the medium, and specifically their sophistic character and rhetoric helping them speak on issues of social justice and change. To understand these texts, I examine each of them in light of their rhetorical situation and the convergence of a multitude of kairotic …
A State-Level Analysis Of Deinstitutionalization And The Impact Of Chlorpromazine, Joni Maria Lee Pow
A State-Level Analysis Of Deinstitutionalization And The Impact Of Chlorpromazine, Joni Maria Lee Pow
LSU Doctoral Dissertations
US state mental hospitals were rapidly depopulated in the decades following 1955. This was a demographic phenomenon of major proportion. The introduction of antipsychotics in 1954 has often been considered instrumental in this population movement. To date, studies of the role of antipsychotics in deinstitutionalization have been state specific, methodologically weak, inconsistent in their findings and fail to consider inter-state differences which could reveal previously unknown causal variables. This study used US Census data and pooled cross sectional time-series analysis to estimate the impact of chlorpromazine and policy changes on mental hospital population movement. To that end, the population movement …
Planning Towards Equal Spatial Accessibility Of Nci Cancer Centers Across Geographic Areas And Demographic Groups In The U.S., Cong Fu
LSU Doctoral Dissertations
The Cancer Centers designated by the National Cancer Institute (NCI) form the “backbone” of the cancer care system in the United States. Awarded via a peer-review process and being re-evaluated every 3 to 5 years, an NCI Cancer Center receives substantial financial support from NCI grants. When the quality standard is not compromised, we argue that an additional criterion for improving and promoting equal accessibility should be factored into the designation and planning process of NCI Cancer Centers. With the help of regression and dummy variables, this research evaluates geographic disparities in spatial accessibility of the NCI Cancer Centers across …
Effect Of Attention Retraining On Pathological Eating Behaviors And Body Dissatisfaction, Jose Silgado
Effect Of Attention Retraining On Pathological Eating Behaviors And Body Dissatisfaction, Jose Silgado
LSU Doctoral Dissertations
Prevalence rates of pathological eating behaviors (PEB) and body dissatisfaction are high among college women, and rates are rising among college men. PEB and body dissatisfaction are also risk factors for the development of clinically significant eating disorders. Further, a lesser studied factor involved in male body dissatisfaction is drive for muscularity. With approximately 70% of college women and 45% of college men experiencing body dissatisfaction, it is important to identify its potential etiological and maintaining risk factors. One such mechanism may be the construct of attentional bias. Research suggests that individuals that engage in PEB or have high levels …
Sourcing And Framing Analysis Of Source Messages In The Coverage Of Armed Conflicts By American And British Foreign Reporters, Ellada Gamreklidze
Sourcing And Framing Analysis Of Source Messages In The Coverage Of Armed Conflicts By American And British Foreign Reporters, Ellada Gamreklidze
LSU Doctoral Dissertations
This dissertation contributes to closing several gaps in mass communication scholarship as well as indicates new avenues for further research in the area of sourcing and framing. This study explored whether reliance on official sources in foreign reporting of international crises is as heavy as the hypothesis predicts, and, by studying messages delivered by official sources in this coverage, revealed how those messages were framed. The results showed that officials were dominant sources of information in all the three media outlets studied. The results also supported the argument that the same indexing mechanisms are at force in foreign reporting and …
Trait Affective, Behavioral, And Cognitive Factors Of Anxiety And Depressive Symptoms In Children And Adolescents: A Hierarchical Model, Reanna Elise Whiting
Trait Affective, Behavioral, And Cognitive Factors Of Anxiety And Depressive Symptoms In Children And Adolescents: A Hierarchical Model, Reanna Elise Whiting
LSU Doctoral Dissertations
Researchers have proposed a vulnerabilities model that attempts to explain the similarities between the internalizing disorders via a hierarchical pathway of trait affectivity and cognitive factors among adults. The current study aimed to replicate and extend this model to symptoms of four internalizing disorders among youth: obsessions and compulsions, generalized anxiety/worry, social anxiety, and depression. Regression-based path analyses utilized data from a community sample of 105 youth aged 12-17 (67.6% female, 80% white, non-Hispanic). Results largely replicated prior models in the adult literature and overall supported a hierarchical paradigm. Trait negative affect and avoidant behavior predicted mid-tier cognitive vulnerabilities (anxiety …
Social Vulnerability In The Wake Of 2010 Bp Oil Spill: The Case Of Southeast Louisiana, Michael Ray Cope
Social Vulnerability In The Wake Of 2010 Bp Oil Spill: The Case Of Southeast Louisiana, Michael Ray Cope
LSU Doctoral Dissertations
The research presented in this dissertation assesses the social impacts of the 2010 BP Deepwater Horizon (BP-DH) oil spill in South Louisiana. The coastal region affected by this disaster is made up of rural communities whose residents rely on the Gulf of Mexico and its resources for their livelihoods. Understanding how this disaster has impacted the general quality of life in spill-affected communities, and how community characteristics have influenced vulnerability and resilience to negative outcomes, has important implications for basic and applied research and public policy. To examine these issues I use one-of-a-kind household survey data from the Community Oil …
All The Science That Is Fit To Blog: An Analysis Of Science Blogging Practices, Paige Brown Jarreau
All The Science That Is Fit To Blog: An Analysis Of Science Blogging Practices, Paige Brown Jarreau
LSU Doctoral Dissertations
This dissertation examines science blogging practices, including motivations, routines and content decision rules, across a wide range of science bloggers. Previous research has largely failed to investigate science blogging practices from science bloggers’ perspective or to establish a sociological framework for understanding how science bloggers decide what to blog about. I address this gap in previous research by conducting qualitative in-depth interviews with 50 science bloggers and an extensive survey of blogging motivations, approaches, content decisions rules, values and editorial constraints for over 600 active science bloggers. Results reveal that science blog content is shaped heavily by not only individual …
The Moderating Effects Of Anxiety On The Relationship Between Attention-Deficit Hyperactivity Disorder And Oppositional Defiant Disorder, Jamarri Raimon Aikins
The Moderating Effects Of Anxiety On The Relationship Between Attention-Deficit Hyperactivity Disorder And Oppositional Defiant Disorder, Jamarri Raimon Aikins
LSU Doctoral Dissertations
Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) are two of the most prevalent childhood disorders, and the co-occurrence of these disorders is associated with an exacerbation of certain behavioral difficulties such as opposition, defiance, and anger when compared to the independent presentation of either disorder. Several researchers have demonstrated that anxiety may buffer against oppositional behavior by inhibiting responses that may lead to aversive consequences. Thus, the current study sought to examine the potentially suppressing role of anxiety when symptoms of ADHD and ODD are both present. A hierarchical regression analysis was conducted to determine the extent to which …

Mishpacha In The American Diaspora: An Exploratory Study Of Highly-Involved Jewish Families, Trevan Glen Hatch
LSU Doctoral Dissertations
Both family and religion are important to a large majority of the population in the United States. In the last few decades, research on religious families has significantly increased. Empirical research on Jewish families, however, is scant. The purpose of this study is to explore contemporary American Jewish family life in relation to Judaism, both cultural and religious. Specifically, the two primary objectives of this study are 1) to examine how Jewish culture and religion may influence and shape Jewish family life; and 2) to examine how family relationships may influence observance of Jewish cultural or religious traditions. This reciprocal …
Effects Of Mirror Exposure And Brief Mindfulness Interventions In Undergraduate Females With Weight And Shape Concerns, Jessica Abaigeal Esmeier Kinsaul
Effects Of Mirror Exposure And Brief Mindfulness Interventions In Undergraduate Females With Weight And Shape Concerns, Jessica Abaigeal Esmeier Kinsaul
LSU Doctoral Dissertations
Risk of disordered eating is high amongst college women in the U.S., often resulting in negative outcomes with regard to health, social functioning and psychological well-being. Disordered eating is associated with multiple aspects of emotional processing, such as emotion regulation, negative affect, and avoidance. Emotional processing difficulties can be addressed with both exposure techniques and mindfulness, which involves present moment awareness with an attitude of acceptance and non-judgment. Interventions using mirror exposure (standing before a mirror and systematically describing the body) to treat disordered eating and body image, particularly those utilizing aspects of mindfulness, show promise in terms of improving …
Investing In The Civic Economy: Social Capital And Choice Neighborhoods, Mary Ellen Brown
Investing In The Civic Economy: Social Capital And Choice Neighborhoods, Mary Ellen Brown
LSU Doctoral Dissertations
Concentrated poverty in inner-city neighborhoods in the United States generates social disorganization and isolation, limiting residents’ access to opportunities for upward mobility. Place-based concentration effects can be detrimental to individual health outcomes and overall community health. Communities require assets and resources across multiple types of capital, and in particular social capital, in order to foster a thriving civic economy. The purpose of this research was to provide a foundation through the study of social capital for pursuing strategic actions to foster a thriving civic economy for residents in a low-wealth neighborhood in Shreveport, Louisiana, that was also the focus of …
A Spatial Analysis Of Obesity And Its Associations With The Built And Natural Environment, Physical Inactivity, And Socioeconomic And Demographic Conditions In The United States Of America, Mustafa Erdem
LSU Doctoral Dissertations
Obesity has strong genetic determinants but the genetic composition of the population does not change rapidly. Thus in this study, the major changes in non-genetic factors such as the development of obesogenic environments and shifting socioeconomic status and lifestyle of individuals are hypothesized to increase the risk of obesity. As the prevalence of obesity continue to increase worldwide with substantial attention in the US, a clearer understanding of how spatial associations between obesity and confounding factors are interrelated is crucial to better tackle the issue of obesity. This study employs the ‘global’ and ‘local’ Exploratory Spatial Data Analysis (ESDA) methods …
Evaluating And Increasing The Range Of Reinforcers For Individuals With Autism Spectrum Disorder, Megan Kliebert Wiggins
Evaluating And Increasing The Range Of Reinforcers For Individuals With Autism Spectrum Disorder, Megan Kliebert Wiggins
LSU Doctoral Dissertations
Prior research has demonstrated the utility of several preference-assessment methodologies to identify stimuli more likely to function as reinforcers for individuals with limited verbal repertoires. However, differing results have been obtained from studies evaluating the reinforcement effects of stimuli identified as high preference by one assessment method but low preference by another assessment method. The first focus of the project was to evaluate the reinforcing efficacy of edible and leisure items based on predictions from preference assessments. Results indicated that edible and leisure items approached frequently during a single-stimulus preference assessment but infrequently during a paired-stimulus preference assessment produced less …
The Edible Landscape: Plant Breeding, Farming, And Sustainbility In Northwest Portugal, Joseph Blanchard Powell
The Edible Landscape: Plant Breeding, Farming, And Sustainbility In Northwest Portugal, Joseph Blanchard Powell
LSU Doctoral Dissertations
This dissertation is an ethnographic analysis of a participatory plant breeding project in northwest Portugal. Participatory plant breeding (PPB) is a crop enhancement strategy that brings farmers and plant breeders together in the effort to conserve crop genetic resources in-situ, improve yield, and increase the overall agricultural sustainability in agriculture. One strategy in PPB calls for plant breeders to spend considerable time on working farms to understand better farmers’ knowledge and skill, and to survey the existing crop genetic diversity within the existing resource limitations on farms. Although there are clear social implications for PPB, the bulk of PPB evaluative …
Familial Relationships Among Muslim Couples And Parents In The United States: A Qualitative Study, Zahra Aqeel Alghafli
Familial Relationships Among Muslim Couples And Parents In The United States: A Qualitative Study, Zahra Aqeel Alghafli
LSU Doctoral Dissertations
Since September 11, 2001, Islam has been the center of many debates, discussions, parodies, and publications. Many Muslims feel that their religion has been portrayed unfairly in Western media. The topics that seem to generate the most criticism relate to gender roles and the treatment of women, both inside the home and in society. The purpose of this project is to employ a qualitative, in-depth interview approach to examine the perceived role of Islam on marital and familial relationships from insiders’ perspectives and to present participants’ reflections on sensitive issues, including gender roles, women’s rights, the concept of Hijab, religious …
Gender Stereotypes And The Strategic Use Of Emotions In The 2008 Elections, Newly Paul
Gender Stereotypes And The Strategic Use Of Emotions In The 2008 Elections, Newly Paul
LSU Doctoral Dissertations
Scholars examining gender bias in elections have found that voters’ stereotypical expectations of women and men candidates affect their vote choice. This dissertation examines gender stereotypes from the perspective of campaigns. Specifically, I examine how ad, candidate and election variables interact with gender stereotypes to determine the use of emotions in political ads. My analysis contains ad data for the 2008 Senate, House and gubernatorial races gathered from the Wisconsin Advertising Project, combined with original content analysis of 1,170,728 ad airings (3,424 unique ads). The results indicate that campaigns’ use of fear, anger, enthusiasm and hope appeals depends to a …
Civic Community, Structural Disadvantage, And Suicide: An Ecological Analysis Of Middle-Age Non-Hispanic White Male Suicide Across The Rural-Urban Continuum, Kayla R. Fontenot
Civic Community, Structural Disadvantage, And Suicide: An Ecological Analysis Of Middle-Age Non-Hispanic White Male Suicide Across The Rural-Urban Continuum, Kayla R. Fontenot
LSU Doctoral Dissertations
This dissertation is a county-level sociological examination of middle-age (35-64) non-Hispanic white male suicides. Although an extensive amount of literature exists on ecological suicide, studies have largely ignored the correlates of suicide among this population group because this stage of the life course has historically demonstrated relatively low and stable rates of suicide. However, suicide rates among middle-age adults have increased dramatically over the last decade, calling for an examination of the correlates of suicide specific to this group. Moreover, the extant suicide literature has largely ignored the possibility of a structural disadvantage-suicide link, as well as the influence of …

Curated Landscapes: The Evolution Of The Postcard Shot, Louise Cheetham
LSU Doctoral Dissertations
This research examines traveling landscape-objects in tourist environments and their impact on cultural identity in America. Traveling landscape-objects include any form of tourist paraphernalia or representation of cultural landscapes. For these purposes, I studied different forms of tourist representation of the Natchez Trace Parkway, an entity of the National Park Service. Research areas include the content, location, and changing medium of traveling landscape-objects, while also addressing their meaning, frequency, quality, role in non-representational arenas, and the future of tourist representations. Methods include detailed cataloguing and analysis of over one thousand images of various shapes and forms ⎯ ranging from early …
