The Relationship Between Elementary School Foreign Language Study In Grades Three Through Five And Academic Achievement On The Iowa Tests Of Basic Skills (Itbs) And The Fourth-Grade Louisiana Educational Assessment Program For The 21st Century (Leap 21) Test, Carolyn Joyce Taylor-Ward

LSU Doctoral Dissertations

The passage of the federal educational legislation, No Child Left Behind Act of 2001, established foreign languages as a core curricular content area. Nonetheless, educational policy makers at the state and local levels often opt to allocate greater resources and give instructional priority to content areas in which students, and ultimately the school systems themselves, are held accountable through high-stakes testing. Although foreign languages are designated as a core content area, instructional emphasis continues to be placed on curricular areas that factor into state educational accountability programs. The present study employed a mixed-methodology design. The primary goal was to explore …

Off Road Vehicle Soil Suitability Analysis Within The Kisatchie National Forest, Jacqueline Avellanoza Prudente Jan 2003

Off Road Vehicle Soil Suitability Analysis Within The Kisatchie National Forest, Jacqueline Avellanoza Prudente

LSU Doctoral Dissertations

Soil degradation due to improper use of off road vehicle (ORV) is among the major problems in the Kisatchie National Forest (KNF), especially in Catahoula (CRD), Evangeline Unit, Calcasieu (ERD), and Kisatchie Ranger (KRD) districts. The USDA-Forest Service (USFS) maintains designated trails within the forest, but many ORV users create their own trails. To address this issue, a research project was initiated in 2001 to assess the suitability of KNF soils for ORV traffic using Geographical Information System (GIS) software. The objectives were achieved by utilizing soil properties, rainfall events, soil trafficability ratings, Keetch-Byram Drought Index (KBDI), and infiltration parameters. …

Diffusion Of A Rodlike Virus In Complex Solutions, Randall Charles Cush Jan 2003

Diffusion Of A Rodlike Virus In Complex Solutions, Randall Charles Cush

LSU Doctoral Dissertations

Entanglement phenomena in concentrated polymer solutions remain an interesting and challenging problem. It is still unclear how entanglement onset affects polymer chain motion at small distance scales. One way to study such motion is to follow the diffusion of a probe particle while increasing the concentration of the polymer. Many such studies have been done using probes ranging from linear and star polymers to various colloidal particles; however, relatively few studies have used rodlike probes. Rodlike probes are potentially more interesting due to the added information that may be gained by following rotational as well as translational diffusion. The anisotropic …

Large Eddy Simulations Of Complex Turbulent Flows, Mayank Tyagi Jan 2003

Large Eddy Simulations Of Complex Turbulent Flows, Mayank Tyagi

LSU Doctoral Dissertations

In this dissertation a solution methodology for complex turbulent flows of industrial interests is developed using a combination of Large Eddy Simulation (LES) and Immersed Boundary Method (IBM) concepts. LES is an intermediate approach to turbulence simulation in which the onus of modeling of “universal” small scales is appropriately transferred to the resolution of “problem-dependent” large scales or eddies. IBM combines the efficiency inherent in using a fixed Cartesian grid to compute the fluid motion, along with the ease of tracking the immersed boundary at a set of moving Lagrangian points. Numerical code developed for this dissertation solves unsteady, filtered …

The Effects Of Signals On Responding During Delayed Reinforcement, Michael E. Kelley Jan 2003

The Effects Of Signals On Responding During Delayed Reinforcement, Michael E. Kelley

LSU Doctoral Dissertations

Functional communication training (FCT) is a commonly used intervention for severe behavior disorders (e.g., Carr & Durand, 1985; Wacker et al., 1990). This treatment is designed to provide individuals with developmental disabilities with a repertoire of responses to attain reinforcement. However, caregivers may be unable or unwilling to provide immediate reinforcement when the treatment is implemented in the natural environment. Recent applied research on responding during delayed reinforcement suggests that responding may not persist when delays exceed 30 s (e.g., Fisher, Thompson, Hagopian, Bowman, & Krug, 2000; Hanley, Iwata, & Thompson, 2001). In contrast, results of basic research suggest that …

Constraint Preserving Boundary Conditions For The Linearized Einstein Equations, Gioel Calabrese Jan 2003

Constraint Preserving Boundary Conditions For The Linearized Einstein Equations, Gioel Calabrese

LSU Doctoral Dissertations

The successful construction of long time convergent finite difference schemes approximating highly gravitating systems in general relativity remains an elusive task. The presence of constraints and the introduction of artificial time-like boundaries contribute significantly to the difficulty of this problem. Whereas in the absence of boundaries the Bianchi identities ensure that the constraints vanish during evolution provided that they are satisfied initially, this is no longer true when time-like boundaries are introduced. In this work we consider the linearization around the Minkowski space-time in Cartesian coordinates of the generalized Einstein-Christoffel system and analyze different kinds of boundary conditions that are …

Genome Analysis: Mutation Analysis Using Near Infrared Laser-Induced Fluorescence (Nir-Lif) And Single Molecule Detection In Microfluidic Devices, Musundi Ben Wabuyele

LSU Doctoral Dissertations

A number of genotyping methods have been developed for mutation analysis, each of which has its own unique advantage. DNA amplification via polymerase chain reaction (PCR) provides an unlimited supply of material for subsequent genetic analysis even in case where only a single copy of the DNA molecule is present in the sample. Research presented in this dissertation first examines the efficiency of in vitro amplification of single copy DNA with subsequent sequencing analysis of PCR product. The PCR products (amplicons) were investigated for possible alteration, distortions or mutations due to the amplification process. The sequencing data for single copy …

Group Theoretical Approach To Pairing And Non-Linear Phenomena In Atomic Nuclei, Kristina D. Launey Jan 2003

Group Theoretical Approach To Pairing And Non-Linear Phenomena In Atomic Nuclei, Kristina D. Launey

LSU Doctoral Dissertations

The symplectic sp(4) algebra provides a natural framework for studying proton-neutron (pn) and like-nucleon pairing correlations as well as higher-J pn interactions in nuclei when protons and neutrons occupy the same shell. While these correlations manifest themselves most clearly in the binding energies of 0+ ground states, they also have a large effect on the spectra of excited isobaric analog 0+ states. With a view towards nuclear structure applications, a fermion realization of sp(4) is explored and its q-deformed extension, sp(4)q, is constructed for single and multiple shells. The su(2)(q) substructures that enter are associated with isospin symmetry and with …

Barriers To Participation In Educational Programs As Perceived By First-Time Enrolling Freshmen In Higher Education, Julie Cason Mcdonald Jan 2003

Barriers To Participation In Educational Programs As Perceived By First-Time Enrolling Freshmen In Higher Education, Julie Cason Mcdonald

LSU Doctoral Dissertations

Institutions of higher education face exceptional challenges in today’s environment. College costs are increasing, funding is decreasing and/or limited, public confidence is diminishing, the work-place is changing, and a shrinking pool of traditional-age college students exists. This creates an environment where colleges and universities find themselves competing for students. So that these institutions of higher education may better understand how to recruit, advise, and retain students, one must consider the barriers first-time freshmen encounter in the pursuit of formal learning as they enter college. The purpose of this study, therefore, was to determine the perceived barriers to educational participation held …

Rainfall-Runoff Control: Variably Saturated Transport For An Infiltration System Controlling Water Quality And Quantity, Zheng Teng Jan 2003

Rainfall-Runoff Control: Variably Saturated Transport For An Infiltration System Controlling Water Quality And Quantity, Zheng Teng

LSU Doctoral Dissertations

Rainfall-runoff impacted by anthropogenic activities transports significant quantities of particulate, aqueous and complexed constituents. These diffuse, unsteady and stochastic event-based loadings are unique challenges for water quality and quantity control. The design, water quality and quantity functions of a partial exfiltration reactor (PER) utilizing Fe-coated-sand and porous pavement (CPP) is examined specifically across three representative rainfall-runoff events. Total concentrations and mass for metals (Zn, Pb, Cu and Cd), suspended solids, and Chemical oxygen demand were reduced significantly. Rainfall-runoff volume and peak flow were reduced and time to peak was extended. Influent dm/dp ratios based on particle analyses suggest that the …

"Magic City" Class, Community, And Reform In Roanoke, Virginia, 1882-1912, Paul R. Dotson, Jr. Jan 2003

"Magic City" Class, Community, And Reform In Roanoke, Virginia, 1882-1912, Paul R. Dotson, Jr.

LSU Doctoral Dissertations

The "Magic City" of Roanoke, Virginia, the fastest growing urban area in the South from 1880 to 1890, exemplified everything that New South boosters claimed to have wanted. The prototypical New South city, Roanoke emerged as an extreme version of all that was supposed to remedy the South's post-Civil War economic stagnation. The city's promise, however, revealed the empty promise of the New South. Despite intensive demographic and industrial growth, by the early twentieth century, Roanoke failed to evolve into the dynamic and modern city prophesied by New South visionaries. Its abysmal conditions, racial turmoil, class conflicts, and superficial "reforms" …

The Novelty Of Improvisation: Towards A Genre Of Embodied Spontaneity, David Alfred Charles Jan 2003

The Novelty Of Improvisation: Towards A Genre Of Embodied Spontaneity, David Alfred Charles

LSU Doctoral Dissertations

Improvisation has often been viewed and valued in terms of its service and resemblance to scripted traditions of theatre. Such a stance seriously undermines the significance and impact of this global performance modality, and has resulted in improvisatory modes being largely ignored or downplayed in modern historical accounts of theatre. This dissertation examines improvisation on its own terms, seeking to understand its unique features, functions and potentials, while freeing it from the heavy shadow of its scripted counterpart. To this end, the theories of literary critic, Mikhail Bakhtin, provide important methodological guideposts and allow the silhouette of the improvisational impetus …

An Investigation Of The Factors That Influence Electronic Information Sharing Between State And Local Agencies, Asli Yagmur Akbulut Jan 2003

An Investigation Of The Factors That Influence Electronic Information Sharing Between State And Local Agencies, Asli Yagmur Akbulut

LSU Doctoral Dissertations

This study investigates the factors that influence local government participation in electronic information sharing with state agencies. Although electronic information sharing has the potential to help government agencies to increase productivity and performance, improve policy-making and provide better public services to the citizens, there is still little information available about the factors that antecede electronic information sharing between local and state agencies. Synthesizing the pertinent literature on interagency information sharing and well-established theories such as diffusion of innovations theory, critical mass theory and social exchange theory, this study proposes that local government participation in electronic information sharing with state agencies …

The Relationship Between Obstructive Sleep Apnea Syndrome And Insomnia: Implications For Treatment, Danae L. Drab Jan 2003

The Relationship Between Obstructive Sleep Apnea Syndrome And Insomnia: Implications For Treatment, Danae L. Drab

LSU Doctoral Dissertations

Obstructive sleep apnea syndrome (OSAS) is a sleep-disordered breathing condition that causes disrupted sleep. Although OSAS is most often associated with daytime hypersomnolence, a number of OSAS patients complain of insomnia, i.e., disorders of initiating or maintaining sleep. If the insomnia in patients with OSAS is secondary to the medical condition, then it would be expected to abate with the successful treatment of OSAS. If, however, the insomnia is primarily of a psychological nature, thus considered primary or psychophysiological insomnia, little to no change in insomnia symptoms would be expected after the treatment of OSAS. The present study examined the …

Dashiki Project Theatre: Black Identity And Beyond, Stanley R. Coleman Jan 2003

Dashiki Project Theatre: Black Identity And Beyond, Stanley R. Coleman

LSU Doctoral Dissertations

At a cast party following a Dillard University theatre production in 1965, Guy West, a senior in theatre, stated that one of his dreams was to perform in his own theatre. These remarks by West proved to be the inspiration that began New Orleans' Dashiki Project Theatre. Prior to 1965, Free Southern Theater was the only theatre of the black experience in New Orleans. Through Dashiki Project Theatre, the black community found another opportunity to relate to black experience through the medium of theatrical performance. In the mid-sixties Theodore Gilliam, a Dillard University professor, and his associates founded Dashiki Project …

Radical Dialectics In The Experimental Poetry Of Berssenbrugge, Hejinian, Harryman, Weiner, And Scalapino, Camille Martin Jan 2003

Radical Dialectics In The Experimental Poetry Of Berssenbrugge, Hejinian, Harryman, Weiner, And Scalapino, Camille Martin

LSU Doctoral Dissertations

In this dissertation, I focus on the work of five contemporary experimental poets - Mei-mei Berssenbrugge, Lyn Hejinian, Carla Harryman, Hannah Weiner, and Leslie Scalapino - in order to demonstrate various aspects of a philosophical dynamic at work in their poetry. The critical debates surrounding experimental poetry often tend to be structured as a dualistic opposition with, for example, the forces of coherence, narrative linearity, and transparent referentiality on one side, and the forces of semantic disruption, narrative discontinuity, and linguistic materiality on the other. On each side, critics attempt to bolster the essential value of one term or set …

Market Timing And Cost Of Capital Of The Firm, Kyojik Song Jan 2003

Market Timing And Cost Of Capital Of The Firm, Kyojik Song

LSU Doctoral Dissertations

Graham and Harvey’s (2001) survey evidence and Baker, Greenwood, and Wurgler (2003) indicate that firm managers try to time debt markets based on term spreads or excess bond returns when choosing the maturity of new debt issues. Whether debt market timing increases firm value via a reduced cost of capital is an empirical question. I examine differences in firm value across non-timers and timers, where timers are defined as firms that follow either a naïve strategy of choosing long-term debt when the term premium is low or a complex strategy from Baker et al. (2003) based on the predictability of …

The Effects Of An Evening Structured Problem-Solving Procedure In Undergraduate College Students With Insomnia, Colleen E. Carney Jan 2003

The Effects Of An Evening Structured Problem-Solving Procedure In Undergraduate College Students With Insomnia, Colleen E. Carney

LSU Doctoral Dissertations

Worry is often reported as interfering with sleep onset and sleep maintenance, and pre-sleep cognitive arousal can persist after successful behavioral treatment of insomnia. The present investigation will examine the effects of a "constructive worry" procedure in an undergraduate population with impaired sleep. Thirty-three undergraduate students who reported three or more nights per week in the last month of sleep onset and/or sleep maintenance problems, either recorded worries and possible solutions (experimental CW group) or recorded worries and completed worry questionnaires (control Worry group) for five nights. As hypothesized, the CW group had decreased pre-sleep cognitive and overall arousal relative …

Narrative Immediacy And First-Person Voice In Contemporary American Novels, Amy Faulds Sandefur Jan 2003

Narrative Immediacy And First-Person Voice In Contemporary American Novels, Amy Faulds Sandefur

LSU Doctoral Dissertations

This study of first-person fictive narration analyzes a selection of contemporary American novels so as to understand and describe more fully a literary effect I call immediacy. I employ the term immediacy to define narrative situations in which little durational gap exists between experience and narration and in which little ideological and emotional distance is communicated between the narrating persona and the subject self. The following chapters provide a close examination of narrative techniques employed by writers in the creation of immediacy and argues that both the tone of the novels and their themes of maturation and self-identity are attributable …
