An Examination Of Autism Symptomatology In Young Children With Family History Of Autism Spectrum Disorder, Jasper Abarte Estabillo Jan 2016

An Examination Of Autism Symptomatology In Young Children With Family History Of Autism Spectrum Disorder, Jasper Abarte Estabillo

LSU Master's Theses

Multiple genetic and environmental factors have roles in the etiology of autism spectrum disorder (ASD). Thus, researchers have become increasingly interested in studying family members of individuals with ASD in order to examine possible risk factors and to identify early markers of the disorder. While family history of ASD may put an individual at risk for developing autism, there is limited research examining how the degree of relationship to the affected individual may be related to an individual’s presenting ASD symptomatology. Because closer familial relationships (i.e., first-degree relatives) have more shared genetic material and tend to have increased common environment …

Control, Care, And Stress: Parenting's Effect On Child Internalizing Symptoms, Maysa Kaskas Jan 2016

Control, Care, And Stress: Parenting's Effect On Child Internalizing Symptoms, Maysa Kaskas

LSU Master's Theses

Theoretical models of childhood psychopathology suggest that the parent-child relationship serves an influential role in the development and maintenance of internalizing disorders such as anxiety and depression. However, there is a great deal of inconsistency in the research literature on the predictive power of parenting variables such as parental control and parental care. Furthermore, these parenting variables are often poorly defined and inconsistently operationalized across studies, hampering interpretation of results and limiting conclusions on the strength of the effect. Additionally, few studies have examined the role of parenting with careful attention to moderators. In order to investigate these problems, 189 …

A Critical Examination Of The Rehearsal Frame Model, Allison Elise Carroll Jan 2016

A Critical Examination Of The Rehearsal Frame Model, Allison Elise Carroll

LSU Master's Theses

The purpose of this study was to evaluate the practical adequacy of Duke’s (1994) rehearsal frame model as a “middle ground” perspective sequential outline of rehearsal events that lead to positive musical change. Observation and video recording of three accomplished high school band directors’ rehearsals generated data that allowed for a comparison between the model and actual practice. Results suggested that all parts of the original model need not be present, nor must they occur in the originally stated order for rehearsal frames to take place and direct students toward positive musical change. An amended model of the rehearsal frame …

Fresh Flow: Where The City Meets The Sea, Wanqin Su Jan 2016

Fresh Flow: Where The City Meets The Sea, Wanqin Su

LSU Master's Theses

The significance of this site lies in its location. It is three miles away from French Quarter, the heart and origin of the city, and eight miles away from Lake Borgne, as well as the Gulf. Regardless of the size, it distinguishes itself on the map as a wedge of green space inserted sharply into densely developed urban space. The site was prosperous cypress swamp six decades ago, too dense to identify lands and water underneath. However, after the Mississippi River Gulf Outlet was dug in the 1960s, it took less than 30 years for it to transformed into brackish …

Influence Of Silicon On The Development Of Anthracnose Of Grain Sorghum, Sanjay Pokhrel Jan 2016

Influence Of Silicon On The Development Of Anthracnose Of Grain Sorghum, Sanjay Pokhrel

LSU Master's Theses

To study the effect of Silicon (Si) with and without a fungicide on anthracnose development of sorghum, several experiments were conducted in the greenhouse and field. In the initial study, different Si rates [0 (control), 0 (lime control), 200, 400, 600, 800 kg Si/ha] were used in a low-Si Alfisol to determine if inoculum densities were affected by Si levels. No differences were observed between inoculum densities of 1*105 and 1*106 conidia/ml in affecting anthracnose development in the greenhouse. Anthracnose severity was found to be lowest in plants treated with 800 kg Si/ha, regardless of inoculum density. In another study, …

Influence Of Motivation On Phonics Effectiveness, Rachel L. Bradley Jan 2016

Influence Of Motivation On Phonics Effectiveness, Rachel L. Bradley

LSU Master's Theses

Reading is a basic life skill, and is paramount to students’ success in school. In fact, skilled readers tend to succeed in subject areas including mathematics, social studies, and science (Valleley & Shriver, 2003). Phonics is one of the cornerstones of learning to read. Without mastering phonics, students are more likely to experience persistent difficulties in reading (Elbro, 1996; Bus and Marinus H. van IJzendoorn, 1999; Rose, 2006). However, student motivation to read can impact the effectiveness of reading programs (Melekoglu, 2011). The current study examines the influence of motivation on the effectiveness of a phonics program with six first-graders …

Efficacy And Feasibility Of Alginate Bait For The Louisiana Commercial Blue Crab (Callinectes Sapidus) Fishery, Elizabeth Lorraine Clowes Jan 2016

Efficacy And Feasibility Of Alginate Bait For The Louisiana Commercial Blue Crab (Callinectes Sapidus) Fishery, Elizabeth Lorraine Clowes

LSU Master's Theses

Louisiana leads all U.S. states in blue crab (Callinectes sapidus) landings, but high fuel and bait costs have hindered commercial fishing productivity of Louisiana in recent years. The primary baitfish, Atlantic menhaden (Brevoortia tyrannus), has steadily increased in price and decreased in availability, while crab prices remain low. To reduce costs for fishermen, an alternative bait was developed that incorporates shrimp waste into a semi-rigid alginate matrix. Lab testing and preliminary field tests show that shrimp-alginate bait may be a suitable alternative to menhaden for Louisiana crab fishermen. I evaluated bait performance by conducting field sampling to compare catch rates …

An Empirical Estimate Of Post-Lgm Grounding-Event Duration In Eastern Ross Sea: Implications From A Comparison With Constraints From New Radiocarbon Dates, Benjamin Krogmeier Jan 2016

An Empirical Estimate Of Post-Lgm Grounding-Event Duration In Eastern Ross Sea: Implications From A Comparison With Constraints From New Radiocarbon Dates, Benjamin Krogmeier

LSU Master's Theses

The West Antarctic Ice Sheet (WAIS) advanced to the outer shelf during the Last Glacial Maximum (LGM) before beginning a rapid retreat to the inner shelf. In the Whales Deep paleo-ice-stream trough, subsurface and geomorphologic evidence shows that grounding-line retreat was interrupted by at least five pauses in the area between the shelf edge and the middle shelf. During the pauses, an overlapping cluster of backstepped grounding zone wedges (GZWs) was deposited. Each GZW represents a grounding event, i.e., a time interval during which the grounding-line position was relatively stable. Seismic correlation and isopach mapping show that the cluster has …

Masculinity And Social Change: Exploring Generative Masculinity Development In Resident Assistant Men Through The Social Change Model Of Leadership Development, Joshua David Finch Jan 2016

Masculinity And Social Change: Exploring Generative Masculinity Development In Resident Assistant Men Through The Social Change Model Of Leadership Development, Joshua David Finch

LSU Master's Theses

In this study, men’s identity development among Resident Assistants (RAs) at Louisiana State University is investigated using a constructivist approach. Societal expectations of men tend to value hegemonic masculinity, which reinforces a drive for dominance, objectification, and high-risk behaviors (Edwards & Jones, 2009). Whereas, generative masculinity is characterized by a sense of responsibility, desire to give back, comfort with self, willingness to confront and break gender stereotypes, and the use of personal strengths to foster wellbeing (Badaszewski, 2014). Many characteristics of generative masculinity align with the Seven C’s of Social Change as described in the Social Change Model of Leadership …

Jockeying For Position: Horse Racing In New Orleans, 1865-1920, Matthew Saul Perreault Jan 2016

Jockeying For Position: Horse Racing In New Orleans, 1865-1920, Matthew Saul Perreault

LSU Master's Theses

From 1865 to 1920, Thoroughbred horse racing matured in Louisiana, developing into a national sport shaped by the processes of modernization, professionalization, and reform. Before the onset of the Civil War, the leaders of Southern thoroughbred horse racing came from the planter elite who used African-American slave horsemen in shows of “amateur” recreation. Combining upper-class recreation with lower and middle-class entertainment, horse racing was a performance of social power. The Civil War devastated the Louisiana turf, scattering horses and men – but sportsmen proposed that post-war racing would help the state recover. The once-independent New Orleans turf joined an interconnected …

Evaluation Of Absorption And Uptake Of Soil- And Foliar-Applied Silicon In Rice And Its Accumulation Under Different Phosphorus Rates, Flávia Bastos Agostinho

LSU Master's Theses

Silicon (Si) fertilization has gained attention in rice (Oryza sativa) production. However, the common soil-applied sources are amended at high rates, whereas the efficacy of foliar Si application is yet to be proven. A series of pot experiments were conducted to (1) elucidate the effects of different Si sources on grain yield and Si accumulation of rice supplied with varying P rates, and 2) evaluate Si absorption and uptake by rice via foliar- and soil-application of Si fertilizers. First, three phosphorus (P) rates (0, 112, and 224 kg P ha-1) and three Si sources: two soil-applied (wollastonite and silicate slag) …

The Effect Of Artificial Light On The Community Structure And Distribution Of Reef-Associated Fishes At Oil And Gas Platforms In The Northern Gulf Of Mexico, Victoria Anne Barker Jan 2016

The Effect Of Artificial Light On The Community Structure And Distribution Of Reef-Associated Fishes At Oil And Gas Platforms In The Northern Gulf Of Mexico, Victoria Anne Barker

LSU Master's Theses

The northern Gulf of Mexico (GOM) contains approximately 2,500 oil and gas platforms, resulting in one of the largest de facto artificial reef systems in the world. As of 2013, 1,227 additional structures had ceased to produce oil and gas and have been decommissioned and removed. While active platforms are lit by high-pressure mercury vapor lights, inactive platforms are only minimally lit for navigation. The positively phototaxic behavior of many fish species causes lit oil platforms to act as fish attraction devices, especially at night. Though a variety of fish species have been reported near these structures, changes in fish …

Reactivity Of Iron-Sulfur Proteins With Nitric Oxide, Md Julkernine Julfiker Jan 2016

Reactivity Of Iron-Sulfur Proteins With Nitric Oxide, Md Julkernine Julfiker

LSU Master's Theses

Iron-sulfur ([Fe-S]) proteins are widely distributed in the biological systems. These proteins are involved in diverse fundamental life processes such as photosynthesis, respiration, ribosome biogenesis, DNA synthesis, and repair. Dysfunction of these proteins or their biogenesis has been implicated in causing cardiovascular diseases, neurodegenerative diseases, and various cancers. Iron-sulfur proteins are highly sensitive to nitric oxide (NO) and readily form dinitrosyl iron complexes (DNICs) upon exposure. Restoration of the iron-sulfur cluster in the NO-modified protein requires a two-step repair process. The first step is to remove DNICs from proteins. The second step is to re-assemble the iron-sulfur cluster in proteins. …

Class-Related Emotions In Physical Education: A Control-Value Theory Approach, Kelly L. Simonton Jan 2016

Class-Related Emotions In Physical Education: A Control-Value Theory Approach, Kelly L. Simonton

LSU Master's Theses

This study investigated a model of students’ control beliefs and task value in physical education (PE). Specifically, it examined relationships among students’ perceptions of their teachers’ communication and instructional clarity, control beliefs and values toward PE, and academic emotions. High school students (N= 529) completed valid and reliable instruments assessing perceptions of teacher characteristics, control, value, enjoyment, and boredom in PE. Descriptive statistics, bivariate correlations, and internal reliability estimates were calculated. A path analysis was used to test the hypothesis that teacher communication and clarity would be related to control-value appraisals which would in turn, positively predict enjoyment or boredom. …

Interactions Between Local Magnetic Moments And Itinerant Charge Carriers In Fe-Based Systems, Yan Wu Jan 2016

Interactions Between Local Magnetic Moments And Itinerant Charge Carriers In Fe-Based Systems, Yan Wu

LSU Doctoral Dissertations

The interactions between magnetic moments and electrons are essential in creating many of the unique properties of magnetic systems. In this thesis, I focused on two Fe-based systems employing multiple experimental techniques to investigate the coupling between localized magnetic moments and conducting charge carriers in two systems with tendencies to order into itinerant magnetic phases.\\ With systematic investigations of Fe$_{1-y}$Co$_y$Si, we discovered a field depended non-Fermi-Liquid (non-FL) behavior near its insulator-metal-transition (IMT) that appears to share the same mechanism as previously discovered in Mn doped FeSi - the underscreened Kondo effect.\\ A similar interaction of the charge carrier moments screening …

Immune Gene Variation And Susceptibility To Upper Respiratory Tract Disease In Gopher Tortoises, Jean Pierre Elbers Jan 2016

Immune Gene Variation And Susceptibility To Upper Respiratory Tract Disease In Gopher Tortoises, Jean Pierre Elbers

LSU Doctoral Dissertations

The immune system defends the host from bacteria, fungi, parasites, and viruses. The immune system is partially under genetic control through immune response genes, such as those of the major histocompatibility complex (MHC) whose nucleotide variation influences the host’s ability to recognize foreign pathogens and can influence disease susceptibility. Populations of threatened species generally possess low levels of genetic variation, and genetically depauperate hosts may be at greater risk of infectious disease contributing to extirpations because they also possess low immunogenetic variation. My dissertation examines the relationship between immunogenetic variation and disease susceptibility and the factors that influence innate immune …

Molecular Simulation Studies Of Hydrophobins Near Gas, Oil And Water Interfaces, Yuwu Chen Jan 2016

Molecular Simulation Studies Of Hydrophobins Near Gas, Oil And Water Interfaces, Yuwu Chen

LSU Doctoral Dissertations

This dissertation contains fundamental, classical molecular simulation studies of the properties of hydrophobins (a unique family of surface-active proteins produced by filamentous fungi in soil) near interfaces involving gas, oil, water, organic solvents and polymers. These studies are relevant to possibly using hydrophobins as natural oil dispersants and in processing of polymers. Preliminary studies by the Russo group suggest that these small surface-active proteins can encapsulate oil, gases and polymers in cylindrical structures. We have performed classic molecular dynamics (MD) simulation and potential of mean force (PMF) calculations of a class I hydrophobin EAS using both all-atom and coarse-grained representations. …

Policies Of Loss: Coastal Erosion And The Struggle To Save Louisiana's Wetlands, Rebecca B. Costa Jan 2016

Policies Of Loss: Coastal Erosion And The Struggle To Save Louisiana's Wetlands, Rebecca B. Costa

LSU Doctoral Dissertations

Since the 1930s, Louisiana has lost approximately 1,800 square miles of land due to the subsidence of the state’s coastal wetlands. By the early 1970s, public officials and private citizens were starting to become aware of the crisis on the coast, and a broad agreement developed among state and federal representatives that action was needed to address the problem. Over the course of nearly forty years, policymakers in Louisiana and Washington, D.C., implemented a series of laws and regulations meant to protect vulnerable ecosystems like the state’s wetlands. In the 1980s, officials also started crafting policies to help restore Louisiana’s …

An Evaluation Of The Utility Of Reading Curriculum-Based Measurement As Progress Monitoring Tools And Predictors Of Comprehension, Haley Elizabeth York Jan 2016

An Evaluation Of The Utility Of Reading Curriculum-Based Measurement As Progress Monitoring Tools And Predictors Of Comprehension, Haley Elizabeth York

LSU Doctoral Dissertations

Many American students struggle with reading, particularly in the area of comprehension. As such, early identification of reading difficulties, use of evidenced-based interventions, and monitoring of student reading progress over time is essential. Curriculum-based measurement (CBM) is a technically adequate, efficient tool whose features and design make it a good candidate for early identification and progress monitoring purposes, especially within a response to intervention framework. However, there is still some uncertainty regarding the utility of reading CBM as progress monitoring tools. Specifically, the literature has suggested that variability in the difficulty of CBM materials may influence how well these tools …

A Phenomenological Investigation Into The Experiences Of High-Achieving African American Male Student Athletes At Predominately White Institutions In The Southeast Region, Runell Jeremiah King

LSU Doctoral Dissertations

This study is an attempt to examine the academic experiences among high achieving African American male student-athletes at predominantly White NCAA Division I institutions in the Southeast region. Most existing literature regarding African American student-athletes at Predominately White Institutions (PWIs) have examined their experiences by highlighting major deficiencies of this groups academic abilities. Most studies emphasize these students’ lack of preparedness, low academic achievement, and high attrition rates (Harper 2005). As a result, little information is available regarding African American male student-athletes who actually excel, achieve at high levels academically, and accomplish goals in which their non-student athlete peers do …

Identifying Leadership Potential In High School Students, Melody Lynn Baham Jan 2016

Identifying Leadership Potential In High School Students, Melody Lynn Baham

LSU Doctoral Dissertations

Leadership potential in regular students is not usually identified by organization advisors at the high school level. Teachers serving as advisors have academic workloads and they are trained to identify the gifted and honors students as leaders, but generally not those at the regular level. Although leadership potential exists in all students, organization advisors tend to seek out those at the top of the class. This study explored how organization advisors, who are also high school teachers, identify student leadership. A group of Student Council and 4-H advisors were interviewed to discover characteristics valued by organization advisors. The advisors were …

The Mnemonic Maid: Joan Of Arc In Public Memory, Tara Beth Smithson Jan 2016

The Mnemonic Maid: Joan Of Arc In Public Memory, Tara Beth Smithson

LSU Doctoral Dissertations

This dissertation examines the relationship between Joan of Arc, postcolonial identity, and public memory. Since her repopularization in the nineteenth century, Joan of Arc has become one of the most emblematic figures of French history. Commemorated in public statuary, celebrated by writers, and championed by politicians, la Pucelle’s story is tantamount to national myth. While Joan of Arc’s centrality to France’s iconic imagining of itself during the spread of its empire has received much critical attention, her postcolonial afterlife remains understudied. This project offers a counterpoint to the prevailing assumption that Joan of Arc has few implications for postcolonial studies …
