Highly Cooperative Tetrametallic Ruthenium-Μ-Oxo-Μ-Hydroxo Catalyst For The Alcohol Oxidation Reaction, Chae S. Yi, Tonya N. Zeczycki, Ilia A. Guzei

Chemistry Faculty Research and Publications

The tetrametallic ruthenium-oxo-hydroxo-hydride complex {[(PCy₃)(CO)RuH]₄(μ₄-O)(μ₃-OH)(μ₂-OH)} (1) was synthesized in two steps from the monomeric complex (PCy₃)(CO)RuHCl (2). The tetrameric complex 1 was found to be a highly effective catalyst for the transfer dehydrogenation of alcohols. Complex 1 showed a different catalytic activity pattern toward primary and secondary benzyl alcohols, as indicated by the Hammett correlation for the oxidation reaction of p-X-C₆H₄CH₂OH (ρ = −0.45) and p-X-C₆H₄CH(OH)CH₃ (ρ = +0.22) (X = …

Heroic Individualism: The Hero As Author In Democratic Culture, Alan I. Baily

LSU Doctoral Dissertations

My study focuses on the literature of democratic morality, with specific reference to the question of "heroic individualism." I attempt to elucidate the notion of heroic individualism by examining three modern democratic moralists whose work occupies the space between politics and literature: Jean Jacques Rousseau, Thomas Carlyle and Friedrich Nietzsche. In brief, I conclude that the central aspiration of heroic individualism is to bridge the gap between writing and action, the Text and the Voice. The dialogue among Rousseau, Carlyle, and Nietzsche reveals that the problem of writing as action is central to heroic-individualist morality. Each of these authors demonstrates …

Topics In Quantum Topology, Khaled Moham Qazaqzeh

LSU Doctoral Dissertations

In chapter 1, which represents joint work with Gilmer, we define an index two subcategory of a 3-dimensional cobordism category. The objects of the category are surfaces equipped with Lagrangian subspaces of their real first homology. This generalizes the result of [9] where surfaces are equipped with Lagrangian subspaces of their rational first homology. To define such subcategory, we give a formula for the parity of the Maslov index of a triple of Lagrangian subspaces of a skew symmetric bilinear form over R. In chapter 2, we find two bases for the lattices of the SU(2)-TQFT-theory modules of the torus …

Reflections On Teaching A Mathematics Education Course, Sarah Elizabeth Smitherman

LSU Doctoral Dissertations

Teaching and learning involve reflexive actions and should be chosen thoughtfully and deliberately, not because someone has decided “what works.” In this study, I examine how complex conversations might offer pedagogical and theoretical (re)considerations in a teacher education course on mathematics. The term “math methods” is a doubly weighted phrase, for both mathematics and methods connote particular ideologies prevalent in current educational rhetoric. In order to unpack the impact of these words, I engage in research based on inquiry, historical analysis, and personal reflections, all of which I use in an eclectic, thoughtful, and explorative manner. The two main research …

"A Kind Providence" And "The Right To Self Preservation": How Andrew Jackson, Emersonian Whiggery, And Frontier Calvinism Shaped The Course Of American Political Culture, Ryan Ruckel

LSU Doctoral Dissertations

Andrew Jackson has inspired numerous biographies and works of historical scholarship, but his religious views have attracted very little attention. Jackson may have been a giant on the political landscape, but he was also a human being, an ordinary American who experienced the same difficulties and challenges as other Americans of the early nineteenth century. Another common experience for many Americans of Jackson’s day included church life, revivals, and efforts to conceptualize every day events within the context of religious experience. Finding out where Jackson stood on religion and what role religion played in his thinking helps situate him as …

Loading And Recovery Behavior Of The Human Lumbar Spine Under Static Flexion, Guntulu Selen Hatipkarasulu

LSU Doctoral Dissertations

Musculoskeletal disorders account for 32 percent of work related injuries and illnesses. Extensive studies have been conducted to understand and explore the factors that affect the development of musculoskeletal disorders to provide effective control strategies. One of the most important factors that allow effective control strategies is the biomechanical factors. Among the biomechanical risk factors, exposures to repetitive static and vibratory activities are known to result in musculoskeletal disorders. A ligamento–muscular reflex activity exists in humans and animals to stabilize the knee, shoulder, elbow, ankle joints, and spine. This reflex activity decreases over time when static loading is applied, which …

Green Theatre: Proto-Environmental Drama And The Performance Of Ecological Values In Contemporary Western Theatre, Kurt Gerard Heinlein

LSU Doctoral Dissertations

The aim of this study is to illustrate the purpose and potential of theatre that promotes a proto-environmental agenda, or Green Theatre, in re-orienting Western behavior and mores in a direction that creates positive socio-environmental change. In correlation, this dissertation will examine the objectives and performance modes of several educational and professional theatre entities that house a distinctly unique Green agenda. The primary performances featured will include Peter Schumann’s Bread and Puppet Theatre, Blue Man Group’s Tubes, performances by Koko the signing lowland gorilla, and Playmakers of Baton Rouge’s production of Habitat Cats.

The Lived Experience Of Nurses Working With Student Nurses In The Acute Care Clinical Environment, Donna Coffey Hathorn

LSU Doctoral Dissertations

The purpose of this phenomenological qualitative study was to describe the lived experience of nurses’ who work with baccalaureate student nurses in the acute care clinical environment. Because of the nursing shortage nursing education is challenged with equipping a safe qualified workforce while preventing or reducing student attrition. Students may choose to leave the profession or receive less than optimal learning experiences when exposed to negative socialization behaviors of nurses while in the clinical environment. Findings from this study can be used to foster collaboration between nursing education and nursing service in the development of positive clinical environments for nurses …

Communicating The Modern Entrepreneurial University In The 21st Century: A Case Study Of Academic Capitalism And Media Messaging In The Pursuit Of Revenues And National Prominence At Louisiana State University, Charles F. Zewe

LSU Doctoral Dissertations

American public universities have passed through three stages of development: the religious, the philanthropic/land-grant, and the federal research university. Squeezed by government budget cuts and demands for more money to pay for research and faculty raises, U.S. higher education has entered a fourth phase, the entrepreneurial university. Public universities are increasingly capitalizing on the intellectual property of their faculty and students to sustain themselves and expand. Administrators spout free-market rhetoric as faculty attempt to commercialize research by creating spin-off companies. Using Louisiana State University as a case study, this dissertation, applies a combination of organizational knowledge creation and resource dependence …

Stage(D) Mothers: Mother-Daughter Tropes In Twentieth-Century American Drama, Kristin Hanson

LSU Doctoral Dissertations

The relationship between mother and daughter is an important one for many women. In learning how to best become a successful member of society, daughters look to their mothers to demonstrate the behaviors and beliefs appropriate to a female. Such explicit and implicit instruction makes the mother-daughter relationship a central one in the socialization of women. Because it is such a powerful site, the mother-daughter relationship has received attention in the world of representation. Of particular import to this study is the representation of the mother-daughter relationship in Twentieth-Century American drama. Recent scholarship has shown that such representations can, however, …

Once Proud Princes: Planters And Plantation Culture In Louisiana's Northeast Delta, From The First World War Through The Great Depression, James Matthew Reonas

LSU Doctoral Dissertations

The Delta country of northeast Louisiana is a richly productive alluvial region stretching south from the Arkansas line to the confluence of the Red and Mississippi Rivers below Natchez. As the source of great cotton fortunes made during antebellum times, it reflected the Old South ideal and, for several decades after the end of the Civil War, remained firmly grounded in this old plantation culture. The economic depression of the 1890s and the coming of the boll weevil in the early 1900s, however, signaled a gradual decline that turned into full-blown dissolution in the years following the First World War. …

The Effectiveness Of Virtual Facilitation In Supporting Gdss Appropriation And Structured Group Decision Making, Harold Joseph Lagroue

LSU Doctoral Dissertations

Since their introduction a quarter of a century ago, group decision support systems (GDSS) have evolved from applications designed primarily to support decision making for groups in face-to-face settings, to their growing use for “web conferencing,” online collaboration, and distributed group decision-making. Indeed, it is only recently that such groupware applications for conducting face-to-face, as well as “virtual meetings” among dispersed workgroups have achieved mainstream status, as evidenced by Microsoft’s ubiquitous advertising campaign promoting its “Live Meeting” electronic meeting systems (EMS) software. As these applications become more widely adopted, issues relating to their effective utilization are becoming increasingly relevant. This …

Evaluating Preference For Reinforcers Under Varying Schedule Requirements In Children With Developmental Disabilities, Tiffany Michelle Kodak

LSU Doctoral Dissertations

Previous research has shown that preference for concurrently available reinforcers can be influenced by the reinforcement schedule (DeLeon, Neidert, Anders, & Rodriguez-Catter, 2001; Tustin, 1994). However, limited research has been conducted on specific variables that may influence preference under various schedule requirements. The present study evaluated the influence of task preference, schedule, and quality of reinforcement on choice between either an arbitrary reinforcer or a functional reinforcer. Five participants diagnosed with Autism participated in the study. In the first phase, we evaluated the effects of task preference and schedule of reinforcement on choice between a 30-s break and a high …

Say It Loud! I'M Black And I'M Proud!: A Study Of Successful Black Female Students Educated In An Urban Middle School, Menthia P. Clark

LSU Doctoral Dissertations

"Acting White" (Fordham & Ogbu, 1986) is a common term among researchers who study academic achievement and racial identity among minority students which signifies the tension some academically successful minority students experience as they excel in school. Black students who contend with such tension may be teased, alienated, or rejected by their peers who view academic achievement as characteristic of White people. In order to avoid the accusation of "acting White," many Black students underachieve, conceal their academic talents, or make no efforts to pursue academic goals. For Black female high-achieving students, "acting White" is laden with gender-specific strategies of …

Psychometric Validity For The Matson Evaluation Of Drug Side Effects And The Akathisia Rating Of Movement Scale, Mark Joseph Garcia

LSU Doctoral Dissertations

Akathisia is a movement disorder characterized by a sense of restlessness and increased motor activity. Movement disorders are primarily an iatrogenic result of mediation use. In the case of akathisia, this syndrome is easily misdiagnosed as a psychiatric disorder. As a result, there is a need to development greater awareness and encourage research on akathisia and the movement disorder field at large. Accordingly, the APA has included research criteria for the movement disorder syndromes in the Criteria Sets and Axes Provided for Further Study of Diagnostic and Statistical Manual since the fourth revision. The purpose of this project was to …

Role Of Hydrocarbon Pollutants, Salinity, Tidal Height, Bioenergetics And Competition In Colonization Of Oyster Reefs By Commensal Assemblages, Yasoma Dhammika Hulathduwa

LSU Doctoral Dissertations

Effects of hydrocarbons, salinity, tidal height, bioenergetics and competition on the oyster reef fauna were studied. Dried oyster shell was exposed to crude oil in the laboratory and plastic trays filled with control and oil-exposed shell were then deployed at two locations, in two seasons and at two tidal levels, with immersion periods of two and five weeks. Salinity exhibited a significant effect with sub tidal site having higher diversity. Hydrocarbon effects were less prominent. To determine effects of cleaners, Corexit 9580 was applied both alone and in combination with oil on cultch. At high concentrations, the cleaner ameliorated hydrocarbon …

Suicide And Community Traumatic Events: Is There A Connection?, Regina T. Praetorius

LSU Doctoral Dissertations

The purpose of this study was to determine if a relationship exists between community traumatic events (CTEs) such as the September 11, 2001 terrorist attacks and the temporal distribution of suicide in a metropolitan Louisiana parish (county) in the Southern United States over the period of January 1, 1994 to December 31, 2004. The researcher used data on suicides (homicides and accidental deaths were used for comparison) in the selected parish to describe the distribution of suicides over the 11 year period. A procedure was developed for identifying and categorizing CTEs sustained by the selected parish (county). A spectral analysis …

Factors Influencing The Importance Of Incorporating Competencies Regarding Mass Casualty Incidents Into Baccalaureate-Degree Nursing Programs As Perceived By Currently Employed Faculty, Kristin Whitty

LSU Doctoral Dissertations

Whether they are naturally occurring, caused by environmental forces, or generated by humans, disasters have placed extraordinary stresses on society. Following September 11, 2001, the Department of Homeland Security was created to protect the nation and coordinate responses to future emergencies at the federal, state, and local levels. However, Governmental agencies can’t handle all aspects of mass casualty events. Healthcare professionals, such as nurses, who are knowledgeable and trained in mass casualty incidents (MCIs) are needed to provide competent care to the victims. Although others expect a knowledgeable nursing response, the majority of nurse educators have not received mass casualty …

Who Said "Words Can Never Hurt?": An Investigation Of Child Weight Status, Childhood Psycosocial Variables, And Later Adult Quality Of Life, Holly Spencer Kihm

LSU Doctoral Dissertations

The first purpose of the research project was to examine the relationship between child weight status and adult quality of life. The second purpose of the research project was to test psychosocial variables as mediators of the relationship between child weight status and adult quality of life. A total of 164 undergraduate and graduate students from Louisiana State University participated in the study. The students completed five online questionnaires that were used to assess variables such as child weight status, adult weight status, history of childhood teasing experiences, child self-concept, and adult quality of life. Several statistical analyses were employed …

On Moment Conditions For The Girsanov Theorem, See Keong Lee

LSU Doctoral Dissertations

In this dissertation, the well-known Girsanov Theorem will be proved under a set of moment conditions on exponential processes. Our conditions are motivated by the desire to avoid using the local martingale theory in the proof of the Girsanov Theorem. Namely, we will only use the martingale theory to prove the Girsanov Theorem. Many sufficient conditions for the validity of the Girsanov Theorem have been found since the publication of the result by Girsanov in 1960. We will compare our conditions with some of these conditions. As an application of the Girsanov Theorem, we will show the nonexistence of an …

Nutrient Constraints On Plant Community Production And Organic Matter Accumulation Of Subtropical Floating Marshes, Guerry O., Jr. Holm Jr.

LSU Doctoral Dissertations

In the cycle of delta growth and decay, peat-forming wetlands span a time and space continuum. Later in the delta cycle, freshwater floating marshes become increasingly removed from external sediment subsidy and internal nutrient cycling controls plant productivity and organic matter accumulation. An interesting question is whether increased external nutrient loading can affect the basic processes that lead to peat formation—plant production and organic matter decomposition. I conducted several field studies to understand whether belowground organic matter accumulation and decomposition were affected with increased nutrient exposure; in addition, the plant community was monitored over three years. A laboratory soil respiration …

Spectral Analysis Of Total Suspended Solids Mixtures For Solids Composition Determination, Curtis W. Sutherland

LSU Doctoral Dissertations

Total Suspended Solids (TSS) analysis provides an initial and very basic measure for study and characterization of water quality. The present tedious procedures used for the identification of different solids constituents present in TSS and for the classification or insight into the origins of those solids are time-consuming and expensive. The research reported herein investigates the use of instrumental analysis using reflectance spectra of TSS as an attractive alternative to sufficiently characterize and identify TSS in a more rapid and economical method that could be used to study TSS transport and to identity TSS points of origin. For this investigative …

Tropical Pyramids: Dung Beetle Richness, Abundance, And Biomass, Meghan Gabrielle Radtke

LSU Doctoral Dissertations

Volume is a proxy for biomass in hard bodied arthropods (P < 0.0001). I constructed biomass-volume equations for Neotropical (P < 0.0001), temperate (P < 0.0001) and 12 Neotropical genera of scarabs, of which 11 were highly significant. The effect of short term (< 1 year) alcohol storage on volume was negligable. I found scarab volume on geologically old soils in the Amazon was one-third that of the geologically young Amazon (P < 0.0001). Species richness (P = 0.0002), Chao 1 (P = 0.0003), Fisher’s  (P = 0.008) and Margalef indices (P = 0.0003) were greater on young soils. Menhinick (P = 0.54), Simpson (P = 0.54) and rarefied species richness (P = 0.24), which correct for sample size differences, indicated no difference in diversity. Young Amazonian soils likely support a higher volume and abundance of scarabs than old soils, but diversity across Amazonia may be similar. I compared beta-diversity of scarab communities across Amazonia. Species rank-abundance curves did not differ among sites whereas volume-abundance distributions and volume-rank abundance curves indicated a larger range of scarab sizes in Brazil than Ecuador. At local levels (<62 km), communities were similar whereas at large distances (>1750 km), they were different. Differences between Brazil and Ecuador may be explained by varied soil age and productivity. I examined the effects of tropical forest fragmentation on scarabs, comparing my results with three other studies from the same site. Among 1, 10, and 100-ha fragments and continuous forest, I found two important trends; beetle biomass and species richness increased with fragment area per sampling effort. Comparing all four studies, diversity increased with fragment size, and by my rarefaction analyses, two studies demonstrated beetle volume increased with fragment size. …

Population Boundaries And Gravitational-Wave Templates For Evolving White Dwarf Binaries, Ravi Kumar Kopparapu

LSU Doctoral Dissertations

We present results from our analysis of double white dwarf (DWD) binary star systems in the inspiraling and mass-transfer stages of their evolution. Theoretical constraints on the properties of the white dwarf stars allow us to map out the DWD trajectories in the gravitational-wave amplitude-frequency domain and to identify population boundaries that define distinct sub-domains where inspiraling and/or mass-transferring systems will and will not be found. We identify for what subset of these populations it should be possible to measure frequency changes and, hence, directly follow orbit evolutions given the anticipated operational time of the proposed space-based gravitational-wave detector, LISA. …

A Stochastic Mesoscopic Cell-Transmission Model For Operational Analysis Of Large-Scale Transportation Networks, Ciprian Danut Alecsandru

LSU Doctoral Dissertations

The cell transmission model (CTM), developed by Daganzo in 1994 was not fully exploited as an operations model for analysis of large-scale traffic networks. Because of its macroscopic / mesoscopic features, CTM offers calibration and computational advantages over microscopic models. This study presents a series of enhancements to the original form of CTM. These enhancements show potential to increase the model’s accuracy and realism of traffic flow representation. For example, topological enhancements and modifications to the flow advancing equation are introduced to allow variable cell lengths and non-discrete movements of vehicles between cells. In addition, implementation of lane-changing behavioral logics …

Red Morningglory (Ipomoea Coccinea L.) Biology And Management In Sugarcane, Curtis A. Jones

LSU Doctoral Dissertations

In field research conducted over two years, red morningglory control 35 days after treatment (DAT) was at least 90 % with atrazine at 3.36 kg ai/ha, diuron plus hexazinone at 1.57 + 0.44 kg ai/ha, flumioxazin at 0.14 kg ai/ha, sulfentrazone at 0.21 kg ai/ha, and metribuzin at 2.52 kg ai/ha. At 49 DAT, atrazine at 4.48 kg/ha provided only 70 % control, which was equivalent to that for diuron plus hexazinone and flumioxazin. Sulfentrazone at 0.21 kg/ha controlled red morningglory at least 93 % 49 DAT and by 77 DAT control was 78 %. From June through October, red …

Detection And Survival Of Escherichia Coli O157:H7 In Cattle Water Troughs And The Effects Of Cetylpyridinium Chloride Against Escherichia Coli O157:H7 Biofilms On The Surface Of Stainless Steel, Sajida Begum Plauche

LSU Doctoral Dissertations

Escherichia coli O157:H7 is an emerging food pathogen that was first identified as a cause of illness in 1982. According to CDC (The Center for Disease Control and Prevention) estimates, E. coli O157:H7 is responsible for about 73,000 illnesses, 2,000 hospitalizations and 60 deaths in the United States each year. Cattle are the principal reservoir of E. coli O157:H7. Contamination of feed and drinking water with cattle feces is an importance factor in the prevalence of infection in cattle which, in turn, results in contamination of food and the environment. Escherichia coli O157:H7 is a very persistent pathogen and has …
