Additional examination of literature on invented spelling in a comprehensive literacy program focused on the connection between reading and writing. Several studies included comparisons of writing instructional methods. Invented spelling has value as an assessment tool for various literacy skills. Criticisms and controversies were reviewed, as well as recommendations for the use of invented spelling to optimize its value in the kindergarten curriculum. Findings of the review …

Integrating Literacy Into The Math Classroom : A Staff Development For Innovative Educators, Kathryn Pollina

Graduate Research Papers

With the collaboration and advice of several mentors and practicing teachers, I found using strategies proven to help students during literacy instruction also had the same effect during mathematics instruction. I took various instructional activities, focused around using reading and writing skills in math, and was able to effectively instruct this group of students. This experience piqued my interest in the connection between literacy and mathematics. As a result, I decided to continue my research into how to effectively integrate these two core subject areas, investigating the efficacy of combining mathematics with literacy instruction.

The Structural Performance Of Timber Connections, Daniel Coleman

Theses

This thesis sets out to assess the behaviour of mechanically fastened timber-to-timber connections. The design aspects of timber connections are described in detail, with particular emphasis on nailed connections. The effects of inherent variations in timber properties on joint behaviour are also described.

The two types of connections considered were:

■ Corbel (cantilever);

■ Splice.

For each connection type, different nail configurations, nail diameters and shaft lengths were used. Testing undertaken was conducted to investigate the influence of a number of nail configurations on a connection’s initial stiffness. The test results, presented using moment- rotation curves are also used to …

Southern Bellas: The Construction Of Mestiza Identity In Southern Narratives, Wendy Aimee Braun

LSU Doctoral Dissertations

This project analyzes representations and self-representations of Mestizas living in areas of the Deep South that lack a significant Latino presence. Incorporating a range of media, I take a comparative approach to Southern cultural narratives and propose a re-reading of these works through an examination of identity formation and cultural negotiation. By centering the Southern Mestiza, this dissertation advances concepts of intersectionality to address the role of region, as well as race and gender, in the representation and experiences of women often overlooked in Southern and U.S. Latino studies. The Introductory chapter summarizes the theoretical framework for the study, including …

Experimental Study Of Lean Blowout With Hydrogen Addition In A Swirl-Stabilized Premixed Combustor, Shengrong Zhu

LSU Doctoral Dissertations

Lean premixed combustion is widely used to achieve a better compromise between nitric oxides emissions and combustion efficiency. However, combustor operation near the lean blowout limit can render the flame unstable and lead to oscillations, flashback, or extinction, thereby limiting the potential range of lean combustion. Recent interest in integrated gasification combined cycle plants and syngas combustion requires an improved understanding of the role of hydrogen on the combustion process. Therefore, in present study, combustion of pure methane and blended methane-hydrogen has been conducted in a swirl stabilized premixed combustor. The measurement techniques implemented mainly include particle image velocimetry, CH*/OH* …

Shades Of Grey: Slaveholding Free Women Of Color In Antebellum New Orleans, 1800-1840, Anne Ulentin

LSU Doctoral Dissertations

This dissertation examines the economic opportunities that free women of color could derive from slaveholding, their motivations, and their impact on New Orleans’ antebellum society and economy. Another aim is to find out the role and impact of free women of color from Saint Domingue (later Haiti), whose arrival in New Orleans doubled the number of free women of color in the city. Finally, the analysis of relationships between free women of color and their slaves and with the diverse population of New Orleans plays an important part in this study. Notarial deeds (sales and purchases of slaves, mortgages of …

Semantically-Aware Data Discovery And Placement In Collaborative Computing Environments, Xinqi Wang

LSU Doctoral Dissertations

As the size of scientific datasets and the demand for interdisciplinary collaboration grow in modern science, it becomes imperative that better ways of discovering and placing datasets generated across multiple disciplines be developed to facilitate interdisciplinary scientific research.

For discovering relevant data out of large-scale interdisciplinary datasets. The development and integration of cross-domain metadata is critical as metadata serves as the key guideline for organizing data. To develop and integrate cross-domain metadata management systems in interdisciplinary collaborative computing environment, three key issues need to be addressed: the development of a cross-domain metadata schema; the implementation of a metadata management system …

Collective Security Or World Domination: The Soviet Union And Germany, 1917-1939, Mark Davis Kuss

LSU Doctoral Dissertations

Since the end of World War II, a rather consistent narrative has appeared regarding the origins of this terrible conflict: Hitler started it. The victorious western powers emerged as innocent victims in the titanic struggle while the USSR, once allied to both Hitler and the west, took on the role of principal villain during the Cold War. With the collapse of communism and the partial opening of Soviet archives, a re-assessment appeared, principally under the heading of the “Collective Security School.” As politically incorrect as it may seem, sober reflection indicates that the Soviet Union was actually the peacemaker in …

Ionic Materials For Applications In Sensing And Optoelectronics, Sergio L. De Rooy

LSU Doctoral Dissertations

Organic salts consist of bulky anions and/or cations whose properties can be tailored for specific purposes. Ionic liquids (ILs) are (semi)organic salts with melting points below 100 ºC. They typically exhibit neglible vapor pressures, high thermal stability, wide liquidus range, and tunable solubility. Moreover specific functions can be built into their respective ions. The first part of the dissertation involves discussions of chiral ionic liquids with additional protic, magnetic, and magneto-luminescent properties, respectively. In addition to their enantioselective sensing capabilities, the ILs may find use in chiral separations and catalysis. The second part of the dissertation involves discussions of fluorescent …

Study On Permanent Magnet Transverse Flux Machine, Oleksandr Dobzhanskyi

LSU Doctoral Dissertations

This dissertation is concentrated mainly on the newest PMTF machine topology proposed and patented by Jacek F. Gieras in March 4, 2010. Such a topology (topology of 2010) is an object of this dissertation. A prototype that was built with 3D Finite Element Method (FEM) modeling of PMTF generator proves that the generator that was built on the basis of topology of 2010 has several significant disadvantages among which the greatest impact have high leakage flux losses. Applying FEM modeling, various steps to improve machine performance have been undertaken. Results obtained from modeling show, that keeping the same diameter and …

The Decline In Trust In The European Union, Nathan Donald Price

LSU Doctoral Dissertations

After twenty years, the European Union is undoubtedly at a crossroads, as its institutions try to manage the sovereign debt crisis in member states and the uncertainty surrounding the future direction of the project. The challenges the European Union has faced, and the response to them, have drawn considerable attention on the capacity of the European Union to manage the interests of the Europeans. In this dissertation, I discuss the process of Europeanization and why it has resulted in suboptimal outputs. Additionally, I discuss the perception of a democratic deficit in the European Union. The purpose of this is to …

Reinhold Niebuhr's Ethics Of Rhetoric, Joseph E. Rhodes

LSU Doctoral Dissertations

This dissertation explores the writings of the American public intellectual and theologian Reinhold Niebuhr (1892-1971). My project is a unique contribution to Niebuhrian studies in that I approach these works from the perspective of a rhetorical theorist. My intention is to parse from Niebuhr’s editorial commentaries, his philosophical inquiries and lectures, his theological treatises, and his sermonic essays an specifically “Niebuhrian ethics of rhetoric.” In order to accomplish this task I investigate the rhetorical situation Niebuhr was embedded in and to which he was responding to at the turn of the twentieth century. Part of the analysis of his rhetorical …

Virgil's Shipwreck: How A Roman Poet Made And Unmade The Epic In The West, Jesse Bryan Burchfield Russell

LSU Doctoral Dissertations

We are still feeling the effects of the Second World War sixty-seven years after its conclusion. Much of post-war thinking has attempted to sort through the roots of the totalitarian ideology that developed in Europe and caused such massive destruction. Marxist and Frankfurt School critics have demonstrated that the roots of Fascism go deeper in the West than the twentieth century and are part and parcel of the West’s combination of technology and myth. Additionally, Post-Colonial critics have pointed out that the horrors of this war were also perpetrated throughout Europe’s colonial endeavors and have undertaken the task of deconstructing …

An Exploration Of Reading Methods In First-Grade: Comparing The Basal Approach And Balanced Literacy, Richelle Leblanc Acosta

LSU Doctoral Dissertations

Few topics in education have sparked as much interest and debate as the teaching of reading. Throughout the past century, instructional approaches have come and gone but one thing has remained constant: the teacher. Behind every effective classroom lies a teacher. It is ultimately the teacher’s decisions that drive daily instruction in the classroom. But what is the best way for teachers to teach children how to read? For decades, researchers have plagued studies seeking to find the best method for accomplishing this. Just as students’ physical characteristics are very diverse, so too are their academic abilities. Reading teachers must …

Synthesis, Characterization, And Self-Assembly Of Porphyrins Conjugated To Superparamagnetic Colloidal Particles For Enhanced Photodynamic Therapy, Javoris Hollingsworth

LSU Doctoral Dissertations

Porphyrins and their derivatives are often used as photosensitizers in photodynamic therapy (PDT), which is a noninvasive antitumor treatment. The photochemical process for PDT involves exciting a photosensitizing agent with visible light, which induces cytotoxicity in the presence of oxygen as a result of forming reactive oxygen species (ROS). The ROS are the responsible components for invoking cell death and destruction of tumors. Although this mechanism is an effective cancer therapeutic, it still has many shortcomings. One major challenge of PDT concerns improving the tumor selectivity and specificity of photosensitizers because porphyrins have nonspecific affinity to tumor cells. The discussed …

Defense Gland Protein From Coptotermes Formosanus, Ioan-Horia Negulescu

LSU Doctoral Dissertations

Coptotermes formosanus Shiraki is the most invasive termite species and has the largest economic impact of all the subterranean termites in the US. Although a lot of work has been done on the determination of chemical composition of frontal gland secretion from different families of termites, the protein component of those secretions was relatively overlooked. This study started with the observation that proteins are present in the frontal gland secretion of Coptotermes formosanus Shiraki soldiers. The goal was to characterize one of these proteins by identifying its DNA sequence which would lead to protein sequence, function, structure and role it …

Training Evaluation In Virtual Worlds: Development Of A Model, Richard N. Landers, Rachel C. Callan

Psychology Faculty Publications

Many organizations have adopted virtual worlds (VWs) as a setting for training programs; however, research on appropriate evaluation of training in this new setting is incomplete. In this article, we address this gap by first exploring the unique issues relevant to evaluation faced by training designers working in VWs. At the macro-organizational level, the primary issue faced is an organizational culture unreceptive to or otherwise skeptical of VWs. At the micro-organizational level, two major issues are identified: individual trainees unreceptive to VWs and general lack of experience navigating VWs. All three of these challenges and their interrelationships may lead to …

Programmable Cmos Analog-To-Digital Converter Design And Testability, Rajiv Soundararajan

LSU Doctoral Dissertations

In this work, a programmable second order oversampling CMOS delta-sigma analog-to-digital converter (ADC) design in 0.5µm n-well CMOS processes is presented for integration in sensor nodes for wireless sensor networks. The digital cascaded integrator comb (CIC) decimation filter is designed to operate at three different oversampling ratios of 16, 32 and 64 to give three different resolutions of 9, 12 and 14 bits, respectively which impact the power consumption of the sensor nodes. Since the major part of power consumed in the CIC decimator is by the integrators, an alternate design is introduced by inserting coder circuits and reusing the …

Drinking Buddies And Their Prospective Influence On Alcohol Outcomes: Alcohol Expectancies As A Mediator, Cathy Lau-Barraco, Abbly L. Braitman, Kenneth E. Leonard, Miguel Padilla

Psychology Faculty Publications

The process by which peers or the social network influence individual alcohol use, particularly among adults, remains a necessary area of research. The purpose of the present study was to examine the longitudinal influence of "drinking buddies" on alcohol outcomes (i.e., alcohol use, heavy drinking, and alcohol-related problems) as mediated by alcohol expectancies of social facilitation. Participants were 1347 (men = 660, women = 687) newly married individuals recruited from the community. They were assessed at the time of marriage and through the fourth wedding anniversary. Longitudinal mediation across time was evaluated using latent growth modeling. Overall, the prospective association …

A Novel Immunomodulatory Subunit Vaccine To Combat The Involvement Of Bovine Respiratory Coronavirus Infections In Shipping Fever, Genevieve Elizabeth Lum

LSU Doctoral Dissertations

Bovine respiratory coronavirus (BRCoV) is a group 2a coronavirus expressing both hemagglutinin-esterase and spike (S) envelope glycoproteins. The S glycoprotein is a primary coronavirus virulence factor responsible for both receptor specificity and membrane fusion-mediated entry into host cells. In addition, the S glycoprotein serves as a major antigen targeted by both the cellular and humoral immune responses and, as such, is an important target for antibody-facilitated virus neutralization. The objective of this research was the design of a safe and effective vaccine against BRCoV using a “prime-boost” vaccination approach. This method utilized an initial DNA vaccine encoding either the soluble …

Investigating Insight As Sudden Learning, Ivan K. Ash, Benjamin D. Jee, Jennifer Wiley

Psychology Faculty Publications

Gestalt psychologists proposed two distinct learning mechanisms. Associative learning occurs gradually through the repeated co-occurrence of external stimuli or memories. Insight learning occurs suddenly when people discover new relationships within their prior knowledge as a result of reasoning or problem solving processes that re-organize or restructure that knowledge. While there has been a considerable amount of research on the type of problem solving processes described by the Gestalt psychologists, less has focused on the learning that results from these processes. This paper begins with a historical review of the Gestalt theory of insight learning. Next, the core assumptions of Gestalt …

A Syntax-Based Reading Intervention For English As Second-Language Learners, Christina Tausch

LSU Doctoral Dissertations

Students with English as second language (ESL) are typically behind monolingual peers in reading comprehension even when phonemic awareness skills, phonics and word recognition are at grade level. The lack of syntactic awareness is one of the reasons cited in multiple studies (August & Shanahan, 2010; Da Fountoura & Siegel, 1995; Lesaux & Siegel, 2003; Lesaux et al., 2006; Chong, 2009). This study investigated the effects of a six week intervention designed to increase syntactic awareness, including meta-awareness of key structures of English for young ESL students in the upper elementary grades. Twenty typically developing ESL students in the fourth …

An Exploratory Study Of Informal Science Learning By Children Ages 2-12 Years At Selected U.S. Children's Gardens, Mary Flake Legoria

LSU Doctoral Dissertations

ABSTRACT This exploratory study was conducted at four children’s gardens in major botanical gardens across the United States to determine if children became more aware and knowledgeable of plants while visiting these gardens. This was determined through the children’s garden stakeholders’ perspectives; the stakeholders of this study were the children and parents who visited the gardens. Their views were acquired through on-site observations and interviews. The purposive sample comprised 64 participants including 40 children (19 girls and 21 boys, ages 2- 12 years). There were 18 mothers, 3 fathers, 3 grandmothers, and 1 grandfather. The 40 children were observed and …

The Lost City: Examining The Relationship Between Science, Philosophy And The Atlantis Myth, Kimberly Hurd

LSU Doctoral Dissertations

Francis Bacon, long considered a minor figure in the founding of modern political thought, is now recognized as one of its foremost thinkers. Bacon not only championed a new type and method of scientific inquiry, he also developed a plan for how modern society could be re-ordered to accommodate and promote scientific progress. Bacon’s scientific writings cannot be wholly understood apart from his political writings, and many of his works combine the two topics so subtly that it is difficult to even place them in a definitive category. My project expands on the previous literature with a detailed analysis of …

Effects Of Hurricanes And Fires On Understory Hardwoods In Pine Savannas, Darin Ellair

LSU Doctoral Dissertations

Disturbance is important in maintaining the open structure of savannas. Frequent fires (every 1-3 years) limit the growth of woody plants, and prevent the transition from savanna to forest by maintaining open space for grasses, herbs, and fire-tolerant longleaf pine. Fires are not the only disturbances in southeastern pine savannas, which also experience hurricanes. Hurricane winds mainly affect the overstory, causing treefalls, increasing light, and adding litter to the understory. Hurricane effects were documented after Hurricane Gustav in 2008. More trees fell where the overstory was present, and produced localized effects on the ground below. Increase in light transmittance was …

Early Behavior Problems In School, Juvenile Delinquency, And Adult Incarceration: A Longitudinal Examination Of Pathways To Crime Among A Ten-Year Birth Cohort In Louisiana, Xian Guan

LSU Doctoral Dissertations

This study utilizes data resources from three state-level departments in Louisiana, Department of Education (DOE), Office of Juvenile Justice (OJJ), and Department of Public Safety and Corrections (DOC), during the period 1996-2008. The sample involves 7th- 12th graders in DOE who were born between 1980 and 1989, with a sample size of N = 408,700 in total. There are two major parts in this study: (1) examining the school-level risk factors among four different offending patterns and making two comparisons among them: the early starters of crime (n = 14,346) vs. late starters (n = 17,107), and the adolescent-limiteds (n …

Osmoregulation And Acid-Base Tolerance In Fish, Shujun Zhang

LSU Doctoral Dissertations

The gill, with a large surface area in intimate contact with the environment, is the primary organ of ion and acid-base regulation in fish. These same characteristics make the gill epithelium particularly susceptible to a number of environmental perturbations, including osmotic challenges and metabolic acidosis. For most freshwater fish, the active uptake of the strong ions, sodium and chloride, are intimately linked with the excretion of acid and base equivalents, respectively. However, fish from the genus Fundulus, are unique in their apparent lack of active chloride uptake at the gills. This unique feature makes limiting Cl- loss through paracellular pathways …

Paradoxes And Consumer Decision-Making, Carolyn Popp Garity

LSU Doctoral Dissertations

Consumers often find themselves faced with conflicting evaluations in which they identify both positive and negative aspects of a purchase or consumption experience. A paradox occurs when the individual is aware of the conflicting evaluations and experiences tension as a result. While there are strong potential implications of paradox, marketing research has been slow to study consumption paradoxes. As a result, many deficiencies exist in the literature, including no consensus as to the definition of consumer paradox, insufficient quantitative measurement, and limited knowledge of the antecedents and consequences of paradox. This dissertation was conducted to address these shortcomings. Essay one …

Investigating The Role Of Genetic Variation In Long Run Economic Outcomes, Charles Justin Cook

LSU Doctoral Dissertations

This dissertation empirically tests whether adaptations resulting from the Neolithic Revolution, or the widespread adoption of sedentary agriculture for sustenance, have led to economic differences. The development of sedentary agriculture constituted an environmen- tal shift from the previous sustenance method of hunting and gathering. This environmental shift resulted in the natural selection of certain traits. I seek to exploit differences in these traits to measure differing economic outcomes. Two main adaptations are considered in this work: the ability to consume milk, or lactose tolerance, and resistance to infectious Eurasian diseases, which is the result of genetic variation. The first essay …
