Concussion Knowledge And Attitudes: The Impact Of Hegemonic Masculinity, Allyssa Jean Schlosser
Concussion Knowledge And Attitudes: The Impact Of Hegemonic Masculinity, Allyssa Jean Schlosser
Theses and Dissertations
Concussions are a significant public health issue, however, there is a lack of knowledge about concussions and a minimization of their severity in society. Prior research has identified various social stigmas, particularly in the world of contact sports, as deterrents for men reporting concussions. This study expands on the reasons why men do not report concussions by exploring the relationship between adherence to hegemonic masculinity and the knowledge and attitudes men have about concussions. College men (N =126) responded to survey questions related to concussion knowledge, concussion attitudes, adherence to toughness, and adherence to restrictive emotionality. Regression analyses were performed …
Variability Of Optical Counterparts To X-Ray Sources Within The Galactic Bulge Survey, Christopher Bradley Johnson
Variability Of Optical Counterparts To X-Ray Sources Within The Galactic Bulge Survey, Christopher Bradley Johnson
LSU Doctoral Dissertations
The Chandra Galactic Bulge Survey (GBS) is a shallow, wide field survey to search for and classify X-ray sources in the Galactic Bulge. Specifically, we are looking for Low Mass X-ray Binaries (LMXBs): systems containing either a neutron star or black hole that is accreting matter from a roughly stellar mass companion via Roche-Lobe overflow. My research uses optical, time-series photometry from the DECam instrument on the Blanco 4.0 m telescope at the Cerro Tololo Inter-American Observatory to identify counterparts to new X-ray sources in the GBS. For the systems that are variable in brightness in the optical, I use …
Design And Implementation Of Qcm Virtual Sensing Schemes For Analyses Of Volatile Organic Compounds, Nicholas Colby Speller
Design And Implementation Of Qcm Virtual Sensing Schemes For Analyses Of Volatile Organic Compounds, Nicholas Colby Speller
LSU Doctoral Dissertations
Sensor arrays have evolved as powerful approaches for providing detection and discrimination of volatile organic compounds (VOCs) as required across numerous analytical applications. Such systems typically comprise a number of cross reactive sensor elements, which generate analyte specific response patterns upon exposure to VOCs, and are known as multisensor arrays. When evaluated using statistical methods, these response patterns facilitate classification of VOCs. As an alternative, a single dynamically operated sensor could also be used to generate analyte specific response patterns. This approach is known as a virtual sensor array (VSA) and can exhibit significant advantages when compared to MSAs. Some …
A Mixed Methods Case Study Exploring Simulation And Caring In Nursing Education, Carla Armstead Harmon
A Mixed Methods Case Study Exploring Simulation And Caring In Nursing Education, Carla Armstead Harmon
LSU Doctoral Dissertations
Current research in nursing education suggests a shift from traditional didactic transmission methods to student-centered pedagogies to prepare nursing students with substantive knowledge necessary for competent practice in a complex healthcare environment. Simulation has emerged as a pedagogy that offers students the opportunity to critically think, solve problems, and care for diverse patients in a nonthreatening, safe environment. As the use of simulation increases, a concern is whether or not it can hinder the development of caring behaviors necessary for competent and compassionate nursing practice. This research was a study of nursing students’ descriptions of the simulation experience, and perceptions …
The Representation Of Disability In The Music Of Alfred Hitchcock Films, John T. Dunn
The Representation Of Disability In The Music Of Alfred Hitchcock Films, John T. Dunn
LSU Doctoral Dissertations
Several of Alfred Hitchcock’s movies feature characters with disabilities. Often, these characters are protagonists, and Hitchcock systematically manipulates his audiences to identify with these characters through the editing process, sound effects, and music. This dissertation will analyze the ways music represents various disabilities in three Hitchcock films. Vertigo (1958) addresses obsession and phobia as its main themes, whereas Psycho (1960) investigates obsession and madness. Finally, The Man Who Knew Too Much (1956) explores muteness, hysteria, and identity in the context of two pieces of diegetic music. Hitchcock made careful notes for the music in his films; songs represent disability through …
Insatiability And Crisis: Using Interdisciplinarity To Understand (And Denaturalize) Contemporary Humans, Sean P. Macdonald, Costas Panayotakis
Insatiability And Crisis: Using Interdisciplinarity To Understand (And Denaturalize) Contemporary Humans, Sean P. Macdonald, Costas Panayotakis
Publications and Research
This chapter illustrates how collaboration between different social sciences can encourage students to think critically about prevailing assumptions regarding human nature. Both the chapter and the pedagogical experience on which it is based investigate the distinctive type of human created by capitalist society. In so doing, it takes a heterodox approach to analyzing the concept of an insatiable human nature through a case study that invites students to critically assess this perspective. This discussion then leads to an investigation and critique of traditional neoclassical Economic assumptions about human behavior, which forms the basis for a case study on the causes …
Quantitative Oil Source-Fingerprinting Techniques And Their Application To Differentiating Crude Oil In Coastal Marsh Sediments, Buffy Marie Meyer
Quantitative Oil Source-Fingerprinting Techniques And Their Application To Differentiating Crude Oil In Coastal Marsh Sediments, Buffy Marie Meyer
LSU Doctoral Dissertations
Oil source-fingerprinting is an environmental forensics technique that uses analytical chemistry to determine the origin of oil residues in environmental samples by comparison to a known or suspected source oil. Currently, the only standardized method for oil source fingerprinting is a qualitative approach that is very effective in almost every oil spill response situation. However, the need for quantitative oil source-fingerprinting methods to complement the qualitative determinations is extremely desired. The research herein aims to utilize data generated by gas chromatography/mass spectrometry (GC/MS) methodologies to test two different quantitative techniques: diagnostic biomarker ratio analysis and chemometrics. The most common crude …
Tracing The Development Of Willie Stark And Its Place In American Opera, Betsy Marie Uschkrat
Tracing The Development Of Willie Stark And Its Place In American Opera, Betsy Marie Uschkrat
LSU Doctoral Dissertations
Highly praised American composer Carlisle Floyd (b. 1925), well known for his musical dramas Susannah (1955) and Of Mice and Men (1970), wrote Willie Stark (1981), commissioned by the Kennedy Center for the Performing Arts and later Houston Grand Opera. Floyd’s libretto and musical score was based upon Robert Penn Warren’s Pulitzer Prize-Winning novel All The King’s Men. Despite the vast amount of publicity it received at the premiere, this opera has only occasionally been performed in the last 35 years. Chapter One discusses Carlisle Floyd’s creation of Willie Stark. Chapter Two discusses the workshop performance of the piece. Chapter …
Relay Selection Strategies For Multi-Hop Cooperative Networks, Hui Sun
Relay Selection Strategies For Multi-Hop Cooperative Networks, Hui Sun
LSU Doctoral Dissertations
In this dissertation we consider several relay selection strategies for multi-hop cooperative networks. The relay selection strategies we propose do not require a central controller (CC). Instead, the relay selection is on a hop-by-hop basis. As such, these strategies can be implemented in a distributed manner. Therefore, increasing the number of hops in the network would not increase the complexity or time consumed for the relay selection procedure of each hop. We first investigate the performance of a hop-by-hop relay selection strategy for multi-hop decode-and-forward (DF) cooperative networks. In each relay cluster, relays that successfully receive and decode the message …
Walter Lippmann's Search For A Sustainable Liberalism, Eric Schmidt
Walter Lippmann's Search For A Sustainable Liberalism, Eric Schmidt
LSU Doctoral Dissertations
Walter Lippmann’s intellectual journey represents the journey of American liberalism in the 20th century: an attempted return from infatuation with the progressive ideals of inevitable historical development and scientific progress to the stability of human rights and freedom. America’s path to defining its brand of liberalism finds expression in the philosophical works of Lippmann, who was at the center of this struggle. Lippmann was a defender of the liberal democratic state whose value as a thinker derives from his attempt to understand the problem of political freedom (are people competent to self-rule in a mass democracy?) throughout this critical time …

“Þe Inglis In Seruage”: Textual Englishness, 1175 – 1330, Joseph Richard Wingenbach
“Þe Inglis In Seruage”: Textual Englishness, 1175 – 1330, Joseph Richard Wingenbach
LSU Doctoral Dissertations
For some time, scholars who study English identity formation in the literature produced between the Norman Conquest and the Hundred Years War have addressed the manifold ways English writers imagined and reconstructed the Anglo-Saxon past as a golden era free of the taint of foreign domination. I find the cultural memory of pre-Conquest England to be only a fraction of what constituted literary Englishness, and my research calls for a more nuanced description of English literary identity during the period in question. The hybrid critical approach I employ is a blend of historicist and structural linguistic methodologies that takes both …

LSU Doctoral Dissertations
The Global boundary Stratotype Section and Point (GSSP) of the base of the Cambrian Drumian Stage was defined at 62 m above the base of the Wheeler formation, at the First Appearance Datum (FAD) of Ptychagnostus atavus (P. atavus), and at 10 meter below the DrumIan Carbon isotope Excursion (DICE) on the Stratotype Ridge in the Drum Mountains western Utah, (Babcock at al., 2004; 2007). Tracing the base of the the Drumian stage to other Middle Cambrian sequences in the House Range Embayment (HRE), a fault-controlled deep-water intrusion into an extensive carbonate platform along the passive margin of western Laurentia, …
Fear No Evil: Making Sense Of Intersectionality And Fear Of Crime Amongst Blacks In High Crime Neighborhoods, Melinda Jackson
Fear No Evil: Making Sense Of Intersectionality And Fear Of Crime Amongst Blacks In High Crime Neighborhoods, Melinda Jackson
LSU Doctoral Dissertations
The extant literature on fear of crime has relied almost entirely upon quantitative data and was criticized as atheoretical due to its focus on the demographic characteristics associated with vulnerability. Emerging qualitative research on fear of crime has begun to overcome this limitation by drawing upon an intersectional lens, but quantitative assessments have yet to fully incorporate this theoretical development. The current study addresses this limitation by analyzing qualitative data collected through semi-structured interviews and quantitative data collected as part of a large-scale survey. The primary goal of this dissertation is to take an intersectional approach to understand the relationships …

We report the extraction of a bed bug mitogenome from high-throughput sequencing projects originally focused on the nuclear genome of Cimex lectularius. The assembled mitogenome has a similar AT nucleotide composition bias found in other insects. Phylogenetic analysis of all protein-coding genes indicates that C. lectularius is clearly a member of a paraphyletic Cimicomorpha clade within the Order Hemiptera.

Molecular Simulation Study Of Oil Hydrocarbons, Dispersants And Other Organics In Atmospheric Air/Water Interfaces, Zenghui Zhang
Molecular Simulation Study Of Oil Hydrocarbons, Dispersants And Other Organics In Atmospheric Air/Water Interfaces, Zenghui Zhang
LSU Doctoral Dissertations
The main objective of this dissertation is to study the interfacial properties of organic contaminants, in particular green leaf volatiles (GLVs), oil hydrocarbons [mainly intermediate-volatile organic compounds (IVOCs) and semi-volatile organic compounds (SVOCs)], as well as surfactant species (i.e. DOSS and Span 80) from Corexit dispersants at atmospheric air/water and air/seawater interfaces. All these compounds can significantly contribute to the formation of secondary organic aerosols (SOAs). Furthermore, our simulation work on IVOCs, SVOCs and Corexit surfactants, combining with experiments from the Valsaraj group, suggests that these compounds can be adsorbed on the surface of seawater droplets and aerosolized into the …

LSU Doctoral Dissertations
Unfavorable consequences of geochemical reactions, such as calcite and silica scaling, in geothermal power plant surface facilities have been discussed in many recent studies. However, the impact of brine-rock interactions related to geothermal projects on reservoir properties has not been addressed fully. In this study, interactions between geothermal fluid and reservoir rocks in two fields located in Vermilion Parish, LA, and Chocolate Bayou, TX, are examined using geochemical modeling. The studied reservoir belongs to the Frio formation. In the geochemical models, the brine is cooled down to the estimated output temperature of a geothermal heat exchanger and re-equilibrated. Then, brine-rock …

Physical Modeling Of Graphene Nanoribbon Field Effect Transistor Using Non-Equilibrium Green Function Approach For Integrated Circuit Design, Yaser Mohammadi Banadaki
LSU Doctoral Dissertations
The driving engine for the exponential growth of digital information processing systems is scaling down the transistor dimensions. For decades, this has enhanced the device performance and density. However, the International Technology Roadmap for Semiconductors (ITRS) states the end of Moore’s law in the next decade due to the scaling challenges of silicon-based CMOS electronics, e.g. extremely high power density. The forward-looking solutions are the utilization of emerging materials and devices for integrated circuits. The Ph.D. dissertation focuses on graphene, one atomic layer of carbon sheet, experimentally discovered in 2004. Since fabrication technology of emerging materials is still in early …

Molecularly Imprinted Polymers For Enantiomer Separations And Biomolecular Sensors, Britney Lyn Hebert
Molecularly Imprinted Polymers For Enantiomer Separations And Biomolecular Sensors, Britney Lyn Hebert
LSU Doctoral Dissertations
Molecularly Imprinted Polymers (MIPs) encompass a wide range of applications by changing the different components, e.g. the template, crosslinker or functional monomers. Of interest among these different applications are separations and sensors. Separations by MIPs traditionally use a chiral pure template but in some cases that chiral pure template may not be available for imprinting. Using chiral (N-α-bismethacyloyl-L-alanine) and achiral (N,O-bisacrylamide ethanolamine) crosslinkers we investigated imprinting of scalemic and racemic template mixtures of Boc-tyrosine enantiomers. The achiral and chiral crosslinkers yielded similar results for the partial separation of enantiomers by scalemic imprinted polymers because separation and recognition are not dependent …

Faculty & Staff Scholarship
The couplings between supermassive black hole binaries (SMBHBs) and their environments within galactic nuclei have been well studied as part of the search for solutions to the final parsec problem. The scattering of stars by the binary or the interaction with a circumbinary disk may efficiently drive the system to sub-parsec separations, allowing the binary to enter a regime where the emission of gravitational waves can drive it to merger within a Hubble time. However, these interactions can also affect the orbital parameters of the binary. In particular, they may drive an increase in binary eccentricity which survives until the …
Intrinsic Electromagnetic Variability In Celestial Objects Containing Rapidly Spinning Black Holes, Fan Zhang
Intrinsic Electromagnetic Variability In Celestial Objects Containing Rapidly Spinning Black Holes, Fan Zhang
Faculty & Staff Scholarship
Analytical studies have raised the concern that a mysterious expulsion of magnetic field lines by a rapidly spinning black hole (dubbed the black hole Meissner effect) would shut down the Blandford–Znajek process and quench the jets of active galactic nuclei and microquasars. This effect is, however, not seen observationally or in numerical simulations. Previous attempts at reconciling the predictions with observations have proposed several mechanisms to evade the Meissner effect. In this paper, we identify a new evasion mechanism and discuss its observational significance. Specifically, we show that the breakdown of stationarity is sufficient to remove the expulsion of the …
Modelling Hydraulic Fracturing Propagation In Heterogeneous Reservoirs Using Cohesive Zone Methods, Miguel Alejandro Gonzalez-Chavez
Modelling Hydraulic Fracturing Propagation In Heterogeneous Reservoirs Using Cohesive Zone Methods, Miguel Alejandro Gonzalez-Chavez
LSU Doctoral Dissertations
The recent success in exploiting low permeability shale reservoirs has heavily relied on hydraulic fracturing to produce hydrocarbons economically in disadvantaged reservoir conditions. Although horizontal drilling significantly increases the contact area between the wellbore and the reservoir, the objective of hydraulic fracturing is set on creating further expanded conductive flow paths into the reservoir. This research uses cohesive zone method to numerically simulate hydraulic fracture propagation in the presence of natural fractures in two- and three-dimensional model. The Cohesive element approach limits fracture propagation to some predefined paths. However, in highly fractured formations since hydraulic fractures are growing through a …

Numerical Modeling Of Wetland Hydrodynamics, Agnimitro Chakrabarti
LSU Doctoral Dissertations
Wave induced erosion accounts for as much as 26% of landloss in coastal Louisiana. This dissertation work, focuses on answering research questions relevant to the design of two shoreline protection methods (a) vegetated wetlands and (b) nearshore breakwaters. Two types of numerical models are used - the three-dimensional (3D) Navier Stokes Equation for small to medium scale experiments and a depth integrated, fully non-linear Boussinesq model for dispersive waves for larger, field scale studies. The former model provides insights into the 3D hydrodynamics of wave interaction with vegetation canopies and breakwaters, while the latter model focuses on the horizontal two …

A Background, Analysis, And Performance Guide For Eugene Goossens's Concerto In One Movement For Oboe And Orchestra, Grace Ellen Woodworth
LSU Doctoral Dissertations
Sir Eugene Goossens (1893-1962) was a leading English composer and conductor of the early twentieth century. Though his music is relatively unknown today, at the height of his popularity as a composer in the 1920s and 30s, Goossens’ music was considered equal to that of British contemporaries Ralph Vaughan Williams, Benjamin Britten, Malcolm Arnold, Arnold Bax, and Gordon Jacob. A public scandal towards the end of his career resulted in his works falling into relative obscurity, with the exception of his oboe concerto. Despite the concerto’s popularity within the oboe community, few in-depth studies of the work exist. This monograph …

Probabilistic And Deep Learning Algorithms For The Analysis Of Imagery Data, Saikat Basu
Probabilistic And Deep Learning Algorithms For The Analysis Of Imagery Data, Saikat Basu
LSU Doctoral Dissertations
Accurate object classification is a challenging problem for various low to high resolution imagery data. This applies to both natural as well as synthetic image datasets. However, each object recognition dataset poses its own distinct set of domain-specific problems. In order to address these issues, we need to devise intelligent learning algorithms which require a deep understanding and careful analysis of the feature space. In this thesis, we introduce three new learning frameworks for the analysis of both airborne images (NAIP dataset) and handwritten digit datasets without and with noise (MNIST and n-MNIST respectively). First, we propose a probabilistic framework …
