As background, an overview of Rachmaninoff’s early life and work is presented in order to provide a clearer understanding of what led him to compose this trio. Of particular importance in the writing of this piece was the direct influence of Peter Tchaikovsky’s Trio, Op 50, which will also figure prominently in the background discussion.


Dynamics Of Resprouting And Forest Regeneration Following Anthropogenic Land Use In The Central Amazon Basin, Scott Lawrence Kosiba Jun 2016

Dynamics Of Resprouting And Forest Regeneration Following Anthropogenic Land Use In The Central Amazon Basin, Scott Lawrence Kosiba

LSU Doctoral Dissertations

Tree mortality is increasing with the effects of climate change and drought across the Amazon Basin while intense fires are becoming more prevalent. Tropical moist forest trees generally lack adaptations that protect against mortality during an intense fire, so anthropogenic burning typically kills high percentages of trees. Following disturbances where prescribed burning is used to limit woody encroachment and to fertilize the soil, abandoned land in central Amazonia becomes dominated by the pioneer tree genus, Vismia. Although the mechanisms by which Vismia comes to dominate previously-burned areas are not known, previous studies on anthropogenic land use and forest succession …

Fear No Evil: Making Sense Of Intersectionality And Fear Of Crime Amongst Blacks In High Crime Neighborhoods, Melinda Jackson Jan 2016

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 …

Molecular Simulation Study Of Oil Hydrocarbons, Dispersants And Other Organics In Atmospheric Air/Water Interfaces, Zenghui Zhang Jan 2016

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 …


Coastal Ecosystem Resiliency After Major Disturbances, Giovanna Mcclenachan Jan 2016

Coastal Ecosystem Resiliency After Major Disturbances, Giovanna Mcclenachan

LSU Doctoral Dissertations

Disturbances are a common occurrence in coastal ecosystems and can provide opportunity for adaptation and renewal in healthy systems; hurricanes bring mineral accretion to a marsh, floods provide a pulse of freshwater and nutrients to estuaries, and fires increase species diversity and abundance in forests. Humans, however, have depleted the resiliency of many coastal systems via top down and bottom up mechanisms, leaving these ecosystems more vulnerable to both natural and anthropogenic disturbances. Louisiana’s wetlands have been modified for centuries via canals, levees, agricultural impoundments, etc., leading to a decreased resiliency to land loss. The Deepwater Horizon (DWH) oil spill …


Theory And Utility Of The Three Isotope Fractionation Relationship, Justin Alan Hayles Jan 2016

Theory And Utility Of The Three Isotope Fractionation Relationship, Justin Alan Hayles

LSU Doctoral Dissertations

The field of isotope geochemistry began with the study of oxygen isotope geothermometry, most famously for carbonates. Traditionally oxygen isotope studies are only concerned with the relationship between one rare isotope, oxygen-18, and the common isotope, oxygen-16. In these cases, the abundance of the third stable isotope, oxygen-17 is ignored because for almost all terrestrial processes the 17O-16O relationship roughly scales with the 18O-16O relationship through a fractionation processes and is thought to not provide any new information. However, the discovery of large “mass independent” isotope effects for ozone chemistry has driven a multitude of uses for triple isotope relationships. …

Amblyomma Maculatum Immunomodulation In Mammalian Models Of Rickettsia Parkeri Rickettsiosis, Kaikhushroo Hormazd Banajee Jan 2016

Amblyomma Maculatum Immunomodulation In Mammalian Models Of Rickettsia Parkeri Rickettsiosis, Kaikhushroo Hormazd Banajee

LSU Doctoral Dissertations

Rickettsia parkeri is an emerging human pathogen and spotted fever group Rickettsia that is transmitted via Amblyomma maculatum (the Gulf Coast tick) in the United States. Since these ticks must feed for several days in order to molt to the next life cycle, they must be able to counteract the host immune response. Despite this fact, there have been few studies that evaluate the immunomodulatory effect of this vector and the resultant influence on rickettsial disease. The hypothesis of this research is that, if A. maculatum feeding modifies the host immune response, this immunomodulation will enhance disease caused by R. …

Testing The Asset-Based Theory Of American Social Welfare: Does A Future-Orientation Mediate The Relationship Between Asset-Ownership And Financial Responsibility?, Louie Fletcher Bickham Iii Jan 2016

Testing The Asset-Based Theory Of American Social Welfare: Does A Future-Orientation Mediate The Relationship Between Asset-Ownership And Financial Responsibility?, Louie Fletcher Bickham Iii

LSU Doctoral Dissertations

The ownership of financial assets protects American households from experiencing the struggles of income poverty. The asset-based theory of American social welfare, which was conceptualized by Professor Michael Sherraden in 1991 and amended in 2001 by other scholars, posited that social welfare programs diminish the prevalence of poverty by enabling households to save funds to purchase assets. This theory has been scantly tested—especially among American households—despite a great amount of funds being invested into programs designed to help low-income American households to build assets. The only previous study that examined the intermediary role of future-orientations on the effect of asset-ownership …


The Ability Of Bull And Stallion Thawed Spermatozoa Refrozen Without Cryoprotectants To Activate Intra- And Interspecies Oocytes, Jose Len Yin Jan 2016

The Ability Of Bull And Stallion Thawed Spermatozoa Refrozen Without Cryoprotectants To Activate Intra- And Interspecies Oocytes, Jose Len Yin

LSU Doctoral Dissertations

Semen cryopreservation has allowed the establishment of genome banks and the large scale propagation of species. The development of simple techniques to cryopreserve semen or alternatives to efficiently use cryopreserved semen from males of valuable genetics that have become infertile will permit continuous propagation of the genetics from these males and may serve as a model for preservation and propagation of endangered species. Sperm cryopreservation without cryoprotectants is a simple process, and offspring have been produced following intracytoplasmic sperm injection (ICSI); however the ability of frozen-thawed sperm refrozen without the addition of cryoprotectants to activate oocytes following ICSI was unknown. …


The Mechanisms Of Auditory Distraction: The Roles Of Interference-By-Process And Attention Capture, Danielle A. Lutfi-Proctor Jan 2016

The Mechanisms Of Auditory Distraction: The Roles Of Interference-By-Process And Attention Capture, Danielle A. Lutfi-Proctor

LSU Doctoral Dissertations

It is generally believed that there are two main mechanisms of auditory distraction: attention capture and interference-by-process. Attention capture is said to occur when sounds drag your attention away from what you are attempting to focus on and harm performance as a consequence. Interference-by-process, meanwhile, states that the processing of the sounds can conflict with the processing needed to complete the task of interest. Whether or not the two mechanisms can jointly lead to distraction is unclear at this time. The following dissertation examined the roles of both distraction mechanisms in a cross-modal variant of the Stroop task, in which …


Complexity Theory And Its Applications In Linear Quantum Optics, Jonathan Olson Jan 2016

Complexity Theory And Its Applications In Linear Quantum Optics, Jonathan Olson

LSU Doctoral Dissertations

This thesis is intended in part to summarize and also to contribute to the newest developments in passive linear optics that have resulted, directly or indirectly, from the somewhat shocking discovery in 2010 that the BosonSampling problem is likely hard for a classical computer to simulate. In doing so, I hope to provide a historic context for the original result, as well as an outlook on the future of technology derived from these newer developments. An emphasis is made in each section to provide a broader conceptual framework for understanding the consequences of each result in light of the others. …


Colonial, Anticolonial, And Postcolonial Myth And Memory In The French-Algerian Narratives Of Albert Camus, Frantz Fanon, And Assia Djebar 1942-1999, Gina Marie Breen Jan 2016

Colonial, Anticolonial, And Postcolonial Myth And Memory In The French-Algerian Narratives Of Albert Camus, Frantz Fanon, And Assia Djebar 1942-1999, Gina Marie Breen

LSU Doctoral Dissertations

Algeria exemplifies a unique case of colonial domination, and of the problems that the colonial system generates. 132 years of colonial rule and settlement led to one of the bloodiest and most difficult battles of decolonization fought in the twentieth century. After eight years of war (1954-1962), which resulted in hundreds of thousands of deaths, Algeria became independent. As the postcolonial society abandoned the French language in an effort to promote Algerian nationalism and create and Arab-Algerian identity, Algeria entered another violent civil war in the 1990s. Thus today, more than fifty years after Algeria gained independence, and twenty years …

A historiography of sex education in the United States is provided to establish context for the sampled texts. A explanation of the content analysis process in general and the methodology specifically used in this study is discussed followed by the …


Professional Wrestling: Local Performance History, Global Performance Praxis, Neal Anderson Hebert Jan 2016

Professional Wrestling: Local Performance History, Global Performance Praxis, Neal Anderson Hebert

LSU Doctoral Dissertations

Professional Wrestling: Local Performance History, Global Performance Praxis, is a work of interdisciplinary scholarship (combining elements of theatre history, performance studies, and philosophy) that addresses an area of performance currently under-researched within the liberal arts and humanities: professional wrestling. My dissertation directs much-needed attention to the fact that professional wrestling is the only kind of live drama many Americans ever see (or even want to see). Although it is no doubt easy for theatre historians and performance theorists to dismiss this performance practice because of its location somewhere between “illegitimate sport” and “lowbrow popular entertainment,” I contend that United States …

Detection And Alleviation Of Pesticide Residue In Food And Water, Olubode James Adeniyi

LSU Doctoral Dissertations

Use of pesticide has become part of modern day agricultural practice. Some pesticides can remain in the environment for decades and contaminate surface water that is used for irrigation of produce. Two studies were conducted- first to examine possible pesticide residue in surface water and some fruits, vegetables and cereals in Louisiana; and second was to alleviate possible pesticide residues in the water using zeolite filtration. Samples of 8 foods (tomato, corn, rice, blueberry, cucumber, cabbage, wheat and melon) and 35 surface waters were studied using a QuEChERS extraction method for food samples and an EPA method for the water …


La Philosophie Poétique D'Édouard Glissant, Un Monisme Vitaliste, David Llorca Jan 2016

La Philosophie Poétique D'Édouard Glissant, Un Monisme Vitaliste, David Llorca

LSU Doctoral Dissertations

Édouard Glissant (1928-2011) is a world famous poet and novelist from French Island Martinique who, following the footsteps of Aimé Césaire, tried to heal the traumatic disruption and resolve the identity crisis of Creole people after the abominations of slavery and colonization by poetic sublimation and engaged thoughts. How is Glissant a philosopher? How does he articu-late poetry and philosophy together? What does he understand by “Relation”, why is it central in his thought and how does the articulation of all his concepts around it make a philosophical en-semble? How original and cohesive is this ensemble? Also, as we know …


Isolation And Identification Of Foodborne Pathogens And Spoilage Bacteria In Environmental And Food Samples, Myriam Evelyn Gutierrez Barberena Jan 2016

Isolation And Identification Of Foodborne Pathogens And Spoilage Bacteria In Environmental And Food Samples, Myriam Evelyn Gutierrez Barberena

LSU Doctoral Dissertations

Escherichia coli O157:H7 has become an important problem for human health in the United States. Scientific studies indicate cattle herds as primary reservoirs of E. coli O157:H7. To diagnose this pathogen, proper isolation and identification methods are crucial. From five different culture media, CT-SMAC and CHROMagar™ O157 results analyzed simultaneously were the best option for an effective detection of environmental E. coli O157. Despite extensive research at feedlots and dairy farms, there is limited information available on the prevalence of E. coli O157:H7 at cow/calf operations. From 28 small-scale cow/calf operations in the state of Louisiana, we observed an 8% …


Riemann-Hilbert Formalism In The Study Of Crack Propagation In Domains With A Boundary, Aleksandr Smirnov Jan 2016

Riemann-Hilbert Formalism In The Study Of Crack Propagation In Domains With A Boundary, Aleksandr Smirnov

LSU Doctoral Dissertations

The Wiener-Hopf technique is a powerful tool for constructing analytic solutions for a wide range of problems in physics and engineering. The key step in its application is solution of the Riemann-Hilbert problem, which consists of finding a piece-wise analytic (vector-) function in the complex plane for a specified behavior of its discontinuities. In this dissertation, the applied theory of vector Riemann-Hilbert problems is reviewed. The analytical solution representing the problem on a Riemann surface, and a numerical solution that reduces the problem to singular integral equations, are considered, as well as a combination of the numerical and analytical techniques …


Rickettsia Felis, Transmission Mechanisms Of An Emerging Flea-Borne Rickettsiosis, Lisa Diane Brown Jan 2016

Rickettsia Felis, Transmission Mechanisms Of An Emerging Flea-Borne Rickettsiosis, Lisa Diane Brown

LSU Doctoral Dissertations

Rickettsia felis is an emerging insect-borne rickettsial pathogen and the causative agent of flea-borne spotted fever. First described as a human pathogen from the United States in 1991, R. felis is now identified throughout the world and considered a common cause of fever in Africa. The cosmopolitan distribution of this pathogen is credited to the equally widespread occurrence of cat fleas (Ctenocephalides felis), the primary vector and reservoir of R. felis. Additionally, R. felis has been identified in other hematophagous arthropods (including numerous species of fleas, ticks, mosquitoes, and mites). Most transmission cycles of pathogenic Rickettsia include transovarial and transstadial …


Peg3 Functions As A Repressor For Its Downstream Genes, An Ye Jan 2016

Peg3 Functions As A Repressor For Its Downstream Genes, An Ye

LSU Doctoral Dissertations

Paternally expressed gene 3 (Peg3) is an imprinted gene that encodes a protein with twelve C2H2 zinc finger domains. Thus, PEG3 protein is predicted to serve as a transcription factor that may regulate other gene expression. Chromatin immunoprecipitation (ChIP) experiment revealed a list of genes that are bound by PEG3, supporting PEG3 is a DNA-binding protein. Genome wide expression analysis using wild type and Peg3 knockout mouse models further suggested that a large number of genes were up-regulated in Peg3 knockout model, including imprinted genes and some tissue-specific genes, suggesting that PEG3 may mainly function as a repressor for its …
