School Readiness And Preschoolers' Attachment Representations: Possible Connections, Katherine A. Darbonne

LSU Master's Theses

The current study examined the possible relationship between preschooler's school readiness and their attachment representations. More specifically, the study examined preschooler's performances on standardized tests and their perceptions of close relationships. The possible connection between school readiness and attachment representations was through children's experiences of stress during standardized testing situations (Fleege, Charlesworth, Burts, & Hart, 1992) and children's stress invoking the use of their internal working models (Bowlby, 1969/1982). The children were administered the Brigance CIBS-R (Glascoe, 1999), a standardized test that was most often used in the local schools to assess school readiness. The children were also videotaped while …

News Narratives And Television News Editing, Keren Esther Henderson

LSU Master's Theses

This study seeks to understand how and why television news editors impose meanings onto news packages through montage editing. Through a qualitative content analysis and in-depth interviews, this study will advance the notably few past narrative editing studies by investigating the norms and routines of television news editors. While other researchers recognize the significance of studying montage editing in television news, this is the first study to clarify the relationship between montage techniques and the creation of television news narratives.

Chagas In Culture And Place: A Mixed Methods Approach To A New Medical Geography Of Chagas Disease In Los Tuxtlas, Mexico, Frances Heyward Currin Mujica

LSU Doctoral Dissertations

This project is concerned with a new medical geography approach to investigating Chagas disease in Los Tuxtlas, Mexico which focuses on the intersection of disease risk and place. More specifically this work will describe the domestic cycle of Chagas disease and the cultural factors that perpetuate its transmission in six communities in the Los Tuxtlas region, Municipio San Andres, Veracruz State, Mexico. Using several collection techniques, such as interviews and house type surveys, as well as identifying and collecting the vector Triatoma dimidiata (including testing them for the parasite Trypanosoma cruzi), this dissertation describes the characteristics of the Chagas landscape …

What Is Natural Resources Law?, Robert L. Fischman

Articles by Maurer Faculty

A recent flurry of new natural resources law casebooks, coming a quarter-century since the publication of the last significant new teaching materials, is an occasion to revisit the boundaries that define the field. The similarities among the casebooks are stronger than their differences, and represent a consensus about what composes natural resources law. The published teaching materials as well as an informal poll of natural resources law professors show a substantial overlap between natural resources and environmental law course coverage. Administrative implementation of statutes dominates both subjects. Both courses typically cover environmental impact analysis and endangered species protection. The new …

Savings Clauses And Trends In Natural Resources Federalism, Robert L. Fischman, Angela King

Articles by Maurer Faculty

This article considers recent trends in federalism, with particular attention to natural resource law's statutory savings clauses. It begins with a case study of elk management in Jackson Hole, Wyoming. The elk controversy shows how a statutory savings clause can provide a state with traction to advance its interests, and demonstrates how the political winds of change can shift the balance of state-federal relations. The article then focuses on the common statutory savings clauses and their roles in circumscribing federal agency authority and establishing a basis for cooperation between federal and state governments. We analyze the interpretive approaches the judiciary …

A Novel Template Stage With Superior Alignment Capability For Nanoimprint And Step And Flash Lithography, Yunmi Jeon

LSU Master's Theses

The high-resolution capabilities of imprinting and step and flash lithography make these techniques strong contenders for the next generation lithography. Unfortunately, alignment remains an area of concern for nanoimprint because it must be completed before the template is moved into contact with the wafer. The large forces on the template during the process, even for step and flash, place additional demands on the stiffness as well as the reproducibility of the template stage. In this thesis, a prototype flexure stage has been developed to meet these demands. A compressive load, slightly below the Euler's limit, is used to produce relatively …

A Geographical Investigation Of Chagas' Disease Risk In The Community Of La Brea, Guatemala, Gerardo J. Boquin

LSU Master's Theses

This thesis will display how the use of a GIS is an important tool in understanding geographic patterns of Chagas' disease vector risk in a rural community in Guatemala. This is an important topic of investigation as Chagas' disease is the leading cause of heart failure in rural Latin America, and yet study has been limited due to a prioritization of national resources to urban diseases. Obviously this can have a severe impact on rural areas, especially if they already lack adequate health care provision. As a response to this deficiency, a collaboration between the Laboratory of Entomology and Applied …

Scholarly Discourse, Public Perceptions, And The Cementing Of Norms: The Case Of The Indian Supreme Court And A Plea For Research, Jayanth K. Krishnan

Articles by Maurer Faculty

For economic and nuclear reasons, India has received considerable attention over the last decade from observers in the United States. But attuned Americans are well-aware of India's rich culture and status as a shining constitutional democracy for most of its post-1947 independent history. For all that India has accomplished, however, its public has long viewed its government officials with great disdain. At the same time, a fascinating norm exists in this society which holds one institution in exceedingly high regard - the Indian Supreme Court.

In this article, I seek to examine what accounts for this counter-intuitive norm. As opposed …

The Individual And Customary International Law Formation, Christiana Ochoa

Articles by Maurer Faculty

A state monopoly on customary international law formation was once required and acceptable, given the status states enjoyed as the sole subjects of international law. Since the drafting of the most commonly cited doctrinal sources of customary international law, legal personhood has been extended to individuals. During this same time period, individuals have come to participate in treaty-making in some key areas of international law, including human rights. The customary international law of human rights, no less than treaty law, has direct effects on individuals. It sees them as the subjects protected by those provisions that have attained the status …

The Catalytic Partial Oxidation Of N-Tetradecane On Rh And Sr Substituted Pyrochlores, Daniel Haynes

LSU Master's Theses

Catalyst deactivation by high levels of sulfur and aromatics limits the catalytic partial oxidation (CPOX) of diesel fuel into a H₂-rich stream for fuel cells. These species poison traditional supported metal catalysts because they adsorb strongly to electron dense metal clusters and promote the formation of carbon on the surface. Therefore, it is logical to spatially distribute an active metal into the lattice of a chemically and thermally stable material to create an active catalyst surface that is less likely to accumulate carbon or be deactivated by sulfur. In this work, Rh metal only and Rh + Sr …

Rna:Dna As An Indicator Of Nutritional Condition And Growth In Larval Naked Goby, Gobiosoma Bosc, Michelle C. Satterwhite

LSU Master's Theses

Developing organism-based metrics for assessing habitat quality is an important tool in conservation and restoration of aquatic habitats. The use of the RNA:DNA ratio as an early indicator of habitat effects on growth of nekton species has been suggested, but requires species-specific laboratory assessment prior to field application. We used food availability in laboratory treatments to simulate differences in habitat quality. Wild Gobiosoma bosc eggs were collected using nest-traps constructed of PVC pipe. Eggs from several different nests collected in the field were hatched in the lab, yielding larvae that were randomly assigned to three feeding treatments in two replicate …

Experimental Investigation Of An Electronically Collimated Radiation Detector For Location Of Gamma-Ray Sources, William H. Hill Jr.

LSU Master's Theses

A electronically collimated prototype detector was built with commercially available cadmium zinc telluride (CZT) modules and assessed by experiment and simulation. Sensitivity was roughly equivalent to a common hand held 1"x1" NaI(Tl) detector. The maximum useful count rate was 300 counts per second (cps) per module. Overall angular error was less than 7°, which is generally less than source placement uncertainty, and angular resolution was between 20° and 40° for several common isotopes with photon energies between 511 keV and 1333 keV. Prototype data and backprojections were used to verify a simple three dimensional model of charge induction in pixellated …

Metabolism And Gene Expression During Diapause In Athropods, Julie Annette Reynolds

LSU Doctoral Dissertations

Arthropods may enter diapause to escape environmental insult. Diapause is an endogenously controlled dormant state defined by developmental arrest and species-specific physiological changes (e.g., metabolic depression and upregulation of compounds that protect cell structure and function). Although physiological changes have been documented for a number of species in diapause, biochemical and molecular regulation of diapause remains largely unexplained. Aerobic metabolism in diapause, Artemia franciscana, embryos is reduced up to 92 % compared with post-diapause embryos. Differences in isolated mitochondria are insufficient to account for respiratory depression because mitochondria in diapause embryos are structurally similar to mitochondria in post-diapause embryos. Respiratory …

Channel Modeling And Resource Allocation In Ofdm Systems, Xiang Gao

LSU Doctoral Dissertations

The increasing demand for high data rate in wireless communication systems gives rise to broadband communication systems. The radio channel is plagued by multipath propagation, which causes frequency-selective fading in broadband signals. Orthogonal Frequency-Division Multiplexing (OFDM) is a modulation scheme specifically designed to facilitate high-speed data transmission over frequency-selective fading channels. The problem of channel modeling in the frequency domain is first investigated for the wideband and ultra wideband wireless channels. The channel is converted into an equivalent discrete channel by uniformly sampling the continuous channel frequency response (CFR), which results in a discrete CFR. A necessary and sufficient condition …

Electrodeposition Of Multilayered Nanostructures For Giant Magnetoresistance And Thermoelectric Applications, Despina Davis

LSU Doctoral Dissertations

The electrodeposition of novel materials such as multilayer nanotubes for giant magneto resistance (GMR) applications and bismuth telluride nanotubes for thermoelectric applications are presented in this dissertation. The motivation for the multilayer electrodeposition is the investigation of giant magnetoresistance (GMR), a change in the material resistance in an applied magnetic field as a consequence of antiferromagnetic coupling. The nanowire high aspect ratio geometry allows the measurement of GMR with the current applied perpendicular to the plane (CPP) of the multilayers, which has been theoretically identified as being larger than the GMR in the (CIP) configuration (current in plane of multilayers). …

Managerial Ability And The Valuation Of Executive Stock Options, Tung-Hsiao Yang

LSU Doctoral Dissertations

The executive compensation literature argues that executives generally value stock options at less than market value because of suboptimal ownership and risk aversion. Implicit in this finding is the assumption that executives are, like shareholders, price takers. That is, they have no ability to influence the outcomes of the firm’s investments. Clearly, executives do have the ability to influence these outcomes, because that is the purpose of granting them the options. In this paper, we develop a model in which managers can exert effort and alter the distribution of the returns from the firm’s investments. We find that when executives …

Quantification Of Muscle Fatigue In Cerebal Palsy And Its Relationship To Impairments And Function, Noelle G. Moreau

LSU Doctoral Dissertations

Three experiments were designed to explore the measurement of muscle fatigue in people with cerebral palsy (CP). The four aims were to 1) develop a feasible and reliable isokinetic protocol to assess muscle fatigue of the knee flexors and extensors in this population, 2) determine if muscle fatigue of the knee flexors and extensors in people with CP differs from subjects without a motor disorder, 3) determine whether muscle fatigue is related to functional measures of activity and participation, and 4) investigate possible contributing factors of muscle fatigue. Results show that muscle fatigue can be reliably assessed through an isokinetic …

Exploring The Quark-Gluon Content Of Hadrons: From Mesons To Nuclear Matters, Hrayr Hamlet Matevosyan

LSU Doctoral Dissertations

Even though Quantum Chromodynamics (QCD) was formulated over three decades ago, it poses enormous challenges for describing the properties of hadrons from the underlying quark-gluon degrees of freedom. Moreover, the problem of describing the nuclear force from its quark-gluon origin is still open. While a direct solution of QCD to describe the hadrons and nuclear force is not possible at this time, we explore a variety of developed approaches ranging from phenomenology to first principle calculations at one or other level of approximation in linking the nuclear force to QCD. The Dyson Schwinger formulation (DSE) of coupled integral equations for …

Which Green Policy?: An Analysis Of The Relationship Between State Environmental Policy And State Economic Growth, Renée L.A. Renegar

LSU Doctoral Dissertations

This project examines state environmental policy and its effect upon state economic growth. State policymakers actively pursue policies intended to positively impact state economic growth. A policy area surrounded by controversy regarding its affect upon economic performance is that of environmental regulation. Prior research indicates that policymakers believe state environmental regulations influence business decisions to invest in certain areas. In this research I seek to determine whether states which deliberately enact more lax environmental regulatory standards succeed in increasing state economic growth. State economic growth is modeled as a function of environmental policy variables and range of national economic and …

Brahms's Ein Deutsches Requiem: Dialectic And The Chromatic Middleground, Patrick Tuck

LSU Doctoral Dissertations

Brahms’s Ein deutsches Requiem (1868) has been the focus of much scholarly research. The present study focuses specifically on the work’s dialectic: the presentation and resolution of a conflict between mortal suffering and eternal joy. It takes an Schenkerian approach to the tonal content of the piece, which provides a musical reflection of the human spiritual journey to the afterlife. It examines how Brahms brings his chosen texts to life with the aid of musical processes such as mixture, register transfer, coupling, covering lines, and contrasting textures. The present study will cite previous authors who have noted the opposing forces …

The Formation Of A Style: Selected Early Works By Hugo Wolf, Jure Rozman

LSU Doctoral Dissertations

Hugo Wolf’s (1860–1903) most pronounced talent was in marrying music and poetry in novel ways, which is clearly demonstrated by his more than 240 art songs. In his early years Wolf composed a series of works for piano solo, published for the first time in 1974 by the Musikwissenschaftlicher Verlag in Vienna. This paper explores these and other formative works in detail, focusing on music-theoretical issues, but also placing them in historical context by means of a brief biography which includes recent discoveries regarding Wolf’s Slovene lineage.

Investigation Of Superficial Dose From A Static Tomotherapy Beam, Koren Suzette Smith

LSU Master's Theses

Abstract Purpose: The TomoTherapy planning system is capable of creating treatment plans that deliver a homogeneous dose to superficial targets. It is essential that the planning system accurately predicts dose to the surface and superficial depths from beams directed at every angle in the axial plane. This work concentrates on measuring and modeling the dose from a static TomoTherapy beam at normal and oblique incidence. It was hypothesized that superficial doses measured from a static TomoTherapy beam agree with doses calculated by the TomoTherapy planning system to within 5% of the maximum dose for angles of incidence from 0¢ª-83¢ª. Methods: …

Rate Change Effects On Acoustic Duration Measures On An Adolescent Who Stutters, Valerie Jean Courville

LSU Master's Theses

The purpose of this study was to determine if reduced rate techniques have an effect on speech motor coordination of an adolescent. A literature review revealed that a reduced rate technique consistently promoted more fluent speech; however, the cause of that increase in fluency is not known. This study proposed three specific questions to determine if there was a shortening of the /s/ phoneme in clustered contexts when compared to singletons, if reducing the rate would cause the adolescent to produce more adult-like shortening patterns, and if the reduced rate technique caused a decrease in stuttering events. One eleven year …

Chromosomal Stability And Epigenetic Modifications Of Fibroblast Cells Used For Nuclear Transfer, Angelica Maria Giraldo Gomez

LSU Doctoral Dissertations

Investigations into the importance of the nuclear integrity of the donor cell prior to nuclear transfer (NT) are limited. In Experiment 1, the proliferative characteristics, chromosomal stability and level of histone phosphorylation in cell lines established by explants and enzymatic dissociation at different population doublings (PDs) were investigated. The cells divided at a constant rate and cell cycle length increased only at the end of the proliferative stage. The level of aneuploidies was high and remained elevated throughout the study independent of the technique used to establish the primary culture. High levels of multinucleated cells and abnormal spindle configurations were …

Visualizing The Menstrual Cycle: Effects Of A Redesigned Cycle Diagram On Community College Biology Students' Learning, Francesca Maria Mellieon-Williams

LSU Doctoral Dissertations

This mixed methods, exploratory study investigated the importance of the menstrual cycle diagram for understanding human reproduction. Several theories were used to support this study including Visual Design Theory (Tufte, 1990, 1997, 2001), and Human Constructivist Theory (Mintzes, Wandersee, Novak 1998). The two sexuality education programs used by society, abstinence-only programs and comprehensive sex education programs were compared to illustrate how this study applies to the current state of sexuality education in the United States. Community college students from two institutions in the southern region of the United States, registered in five introductory biological science courses, participated in a unit …

Genotypic Variability And Inheritance Of Iron And Zinc In Sweetpotato, Michael William Courtney

LSU Master's Theses

Sweetpotato [Ipomœa batatas (L.) Lam.] is a major subsistence crop in Sub-Saharan Africa, where iron and zinc deficiency in humans is an important health problem. A sweetpotato cultivar suited for subsistence farming, with high iron and zinc concentration, would be important in alleviating these deficiencies. The main objective of this research was to identify the extent of genetic variability of iron and zinc concentration in sweetpotato germplasm. An important subcomponent of this research was to determine the heritability of iron and zinc in sweetpotato. Protocol development studies were also conducted to aid in determining proper sampling technique. The results of …
