Influences Of Selected Demographic Variables On The Career Decision-Making Self-Efficacy Of College Seniors, Mary Edith Whitehead Stacy

LSU Doctoral Dissertations

The study was designed (1) to describe college seniors demographically, (2) to assess college seniors perceived level of career-decision making self-efficacy (CDMSE), (3) to examine the relationship between the participant’s CDMSE scores, as measured by the subscales of the Career Decision Self-Efficacy Scale – Short Form© (CDSE-SF), and selected demographic characteristics, and; (4) to determine if a model existed to explain a significant portion of variance in CDMSE based on the selected demographic characteristics. The sample consisted of 382 college seniors attending a four-year public university completing the application for graduation process in the 2002 fall semester. Along with the …

Studies On Rice Transformation And The Use Of Transformed Plants [Electronic Resource], Qiming Shao

LSU Doctoral Dissertations

This research was conducted to enhance utilization of the Liberty herbicide resistance transgene in rice. Non-lethal methods to determine the sensitivity of transgenic rice plants to hygromycin B and Liberty were developed, tested and used in this research. Four homozygous transformed plants were selected to make reciprocal crosses with their non-transformed parent cultivars Taipei 309 and Nipponbare. Their resistances to Liberty and hygromycin B were controlled by the closely linked single dominant genes bar and hpt. Some non-resistant phenotypes in the F2 populations were due to gene silencing. The bar gene in some of these plants were allelic and some …

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 …

A Critical Analysis Of Female Doctoral Student Advisement: Implications For Program Satisfaction, Angele Marie Thibodeaux

LSU Doctoral Dissertations

The purpose of this study was to seek a greater understanding of the female doctoral student experience. In particular, the emphasis of this study is on exploring the dynamics and consequences of the advisor/advisee relationships that female doctoral students experience. This study was designed to address the role of ethnicity and gender in: (a) the selection of an advisor; (b) the quality and characteristics of the advisor/advisee relationship; (c) the impact of the advisor/advisee relationships on program satisfaction; and (d) the impact of external factors on the advisor/advisee relationship and academic experience of female doctoral students. To accomplish this goal, …

The Relationship Between Selected Housing And Demographic Charateristics And Employment Status Among Rural, Low-Income Families, Ann Allgood Berry

LSU Doctoral Dissertations

This study was a secondary analysis of wave one data of the Rural Families Speak project, a multi-state longitudinal Agricultural Experiment Station project that focused on assessing changes in the well-being and functioning of rural low-income families in the context of welfare reform. Quantitative analysis was conducted to determine the housing situations of the families and the relationships of these factors with the family economic and cognitive well-being and employment circumstances of study participants. Discriminant analysis was used to develop a model to predict the employment circumstances (employed, not employed) of the participants. Housing costs usually take the first and …

The Dual Paths Of A Political Movement: Convergence And Divergence In Contemporary Conservative Public Address, Lyman Davis Hunt

LSU Doctoral Dissertations

This study examines the rhetorical choices made in public addresses by members of the contemporary conservative movement in the United States during the 1990s. The contemporary conservative movement in this instance is defined as a post World War II phenomenon. Specifically, it is argued that the popular notion of a unified conservative ascendence in America is but an illusion. Rather, two distinct tribes of conservatives, the economic and the traditional conservative, participate in a rhetorical homology that serves to hide significant ontological differences beneath the dialectical God terms freedom and order. Additionally, the charismatic nature of the term freedom authorizes …

Reporting The Movement In Black And White: The Emmett Till Lynching And The Montgomery Bus Boycott, John Craig Flournoy

LSU Doctoral Dissertations

This dissertation examines media coverage of two events in the Civil Rights Movement-the lynching of Emmett Till in 1955 and the Montgomery bus boycott in 1955-56. The study focuses on three publications aimed primarily at white audiences (Life, Look and the New York Times) and two aimed primarily at black audiences (the Birmingham World and Jet). The dissertation seeks to answer several questions. How did mainstream news organizations cover black Americans in the decades prior to the 1950s? In reporting on the Till murder case and the Montgomery bus boycott, did coverage by mainstream news organizations change? If so, in …

Chairmen Of The Joint Chiefs Of Staff: Monitoring The Evolution Of An Agency Through Rhetorical Snapshots Of Speeches By Generals Omar N. Bradley, Earle G. Wheeler, George S. Brown And Colin L. Powell, John Robert Foster

LSU Doctoral Dissertations

There is a need to examine the long term rhetorical strategies of military spokesmen within a democratic state characterized by civilian hegemony. This study uses Kenneth Burke's discussion of cluster analysis to discover the various recurring themes from Chairman to Chairman of the Joint Chiefs of Staff. This form of analysis enabled the researcher to document periodic variances or shifts in emphasis among the four Chairmen whose speeches will be examined. The investigation involved two speeches representative of each of these four distinct periods of the discourse of Chairmen of the Joint Chiefs of Staff, one given to a civilian …

Social Sector Participatory Development In Honduras: A Process Across Institutions, Culturesval And Continents, Denese Ashbaugh Vlosky

LSU Doctoral Dissertations

This research was conducted to determine whether our participatory process of curriculum development for vocational technical schools in Honduras was successful. This study analyzed program documents and correspondence to answer two questions: a) How did individual stakeholders perceive and negotiate the participatory process? and b) What factors --individual and environmental-- promoted and impeded the participatory process of development in this project? Participatory development concepts applied to Human Ecology Theory guided this research. Qualitative methodologies were utilized to develop the curriculum—Phenomenology-- and to evaluate the process of development—Grounded Theory and Matrix Analysis. An analysis of individual counterpart contacts revealed that stakeholder …

Jazz And The Cultural Transformation Of America In The 1920s, Courtney Patterson Carney

LSU Doctoral Dissertations

In the early twentieth century jazz was a regionally based, racially defined dance music that featured solo and collective improvisation. Originating in New Orleans, jazz soon spread throughout the country as musicians left the South for better opportunities-both economic and social-elsewhere in the country. Jazz greatly increased in popularity during the 1920s. No longer a regional music dominated by African Americans, jazz in the 1920s helped define a generation torn between the Victorian society of nineteenth century America and the culture of modernity that was quickly defining the early twentieth century. Jazz and its eventual popularity represented the cultural tensions …

The Effects Of Employee Service Quality Provision And Customer Personality Traits On Customer Participation, Satisfaction, And Repurchase Intentions, Jeannie Denise John

LSU Doctoral Dissertations

This research investigates customer-employee interaction during service encounters, and whether the relationships between customer personality traits and quality of the employee’s service delivery will impact the customer’s participation, satisfaction, and repurchase intentions. Consumer personality is differentiated in terms of the self-monitoring (Snyder 1987) and locus of control (Rotter 1966) traits. Service quality provision is manipulated in terms of technical versus functional quality inputs, and whether these inputs are provided in a positive (i.e., good/superior) or negative (i.e., bad/poor) manner. These manipulations yield four combinations of service quality inputs: 1) positive technical and functional quality inputs; 2) positive technical, but negative …

Faculty Publications

We have designed, constructed, and put into operation a large-area CCD camera that covers a large fraction of the image plane of the 1 m Schmidt telescope at Llano del Hato in Venezuela. The camera consists of 16 CCD devices arranged in a 4 × 4 mosaic covering 2.°3 × 3.°5 of sky. The CCDs are 2048 × 2048 LORAL devices with 15 μm pixels. The camera is optimized for drift-scan photometry and objective-prism spectroscopy. The design considerations, construction features, and performance parameters are described in the following paper.

A Quantum Rosetta Stone For Interferometry, Hwang Lee, Pieter Kok, Jonathan P. Dowling

Faculty Publications

Heisenberg-limited measurement protocols can be used to gain an increase in measurement precision over classical protocols. Such measurements can be implemented using, for example, optical Mach-Zehnder interferometers and Ramsey spectroscopes. We address the formal equivalence between the Mach-Zehnder interferometer, the Ramsey spectroscope and a generic quantum logic circuit. Based on this equivalence we introduce the 'quantum Rosetta stone', and we describe a projective-measurement scheme for generating the desired correlations between the interferometric input states in order to achieve Heisenberg-limited sensitivity. The Rosetta stone then tells us that the same method should work in atom spectroscopy.

Strong Founder Effect In Drosophila Pseudoobscura Colonizing New Zealand From North America, J. Reiland, S. Hodge, Mohamed A.F. Noor

Faculty Publications

The North American native species Drosophila pseudoobscura was first identified in New Zealand in the last few decades. Here, we have studied the genetic consequences of its spread across the Pacific Ocean. Using 10 microsatellites that are highly variable in North American populations, we found that the New Zealand population has substantially fewer alleles, a much lower average heterozygosity, and significantly different allele frequencies at these loci. We have discussed the relative sensitivity of these parameters for detecting the founding event. X-linked loci were more strongly differentiated between continents than autosomal loci, as reflected by larger changes in allele frequencies …

Triples Of Arrangements And Local Systems, Daniel C. Cohen

Faculty Publications

For a triple of complex hyperplane arrangements, there is a well-known long exact sequence relating the cohomology of the complements. We observe that this result extends to certain local coefficient systems, and use this extension to study the characteristic varieties of arrangements. We show that the first characteristic variety may contain components that are translated by characters of any order, thereby answering a question of A. Suciu.

Local Systems On Nilpotent Orbits And Weighted Dynkin Diagrams, Pramod N. Achar, Eric N. Sommers

Faculty Publications

We study the Lusztig-Vogan bijection for the case of a local system. We compute the bijection explicitly in type A for a local system and then show that the dominant weights obtained for different local systems on the same orbit are related in a manner made precise in the paper. We also give a conjecture (putatively valid for all groups) detailing how the weighted Dynkin diagram for a nilpotent orbit in the dual Lie algebra should arise under the bijection. © 2002 American Mathematical Society.

Non-Semisimple Hopf Algebras Of Dimension P2, Siu Hung Ng

Faculty Publications

Let H be, finite-dimensional Hopf algebra with antipode S of dimension pq over an algebraically closed field of characteristic 0, where p ≤ q are odd primes. If H is not semisimple, then the order of S4 is p, and Tr(S2p) is an integer divisible by p2. In particular, if dim H = p2, we prove that H is isomorphic to a Taft algebra. This completes the classification for the Hopf algebras of dimension p2. © 2002 Elsevier Science (USA). All rights reserved.

Su(3) Versus Deformed Hartree-Fock State, Calvin W. Johnson, Ionel Stetcu, J. P. Draayer

Faculty Publications

Deformation is fundamental to understanding nuclear structure. We compare two ways to efficiently realize deformation for many-fermion wave functions, the leading SU(3) irreducible representation and the angularmomentum-projected Hartree-Fock state. In the absence of single-particle spin-orbit splitting the two are nearly identical. With realistic forces, however, the difference between the two is nontrivial, with the angular-momentum-projected Hartree-Fock state better approximating an "exact" wave function calculated in the fully interacting shell model. The difference is driven almost entirely by the single-particle spin-orbit splitting.

Relaxation Through Homogenization For Optimal Design Problems With Gradient Constraints, R. Lipton

Faculty Publications

The problem of the relaxation of optimal design problems for multiphase composite structures in the presence of constraints on the gradient of the state variable is addressed. A relaxed formulation for the problem is given in the presence of either a finite or infinite number of constraints. The relaxed formulation is used to identify minimizing sequences of configurations of phases.

Honest Abe ?: Biography Examines Lincoln's Ethics, Harold Holzer

Civil War Book Review

How was it that a man born to the most grueling poverty on the remote western prairie, lacking in formal education--merely the son of "a wandering laboring boy," in his own words, and early in life, little better himself--rose from obscurity to the American presidency, and from there to immortality?....

Laurasian Migration Explains Gondwanan Disjunctions: Evidence From Malpighiaceae, Charles C. Davis, Charles D. Bell, Sarah Mathews, Michael J. Donoghue

Faculty Publications

Explanations for biogeographic disjunctions involving South America and Africa typically invoke vicariance of western Gondwanan biotas or long distance dispersal. These hypotheses are problematical because many groups originated and diversified well after the last known connection between Africa and South America (≈105 million years ago), and it is unlikely that "sweepstakes" dispersal accounts for many of these disjunctions. Phylogenetic analyses of the angiosperm clade Malpighiaceae, combined with fossil evidence and molecular divergence-time estimates, suggest an alternative hypothesis to account for such distributions. We propose that Malpighiaceae originated in northern South America, and that members of several clades repeatedly migrated into …

Group Actions On Central Simple Algebras, Daniel S. Sage

Faculty Publications

Let G be a group, F a field, and A a finite-dimensional central simple algebra over F on which G acts by F-algebra automorphisms. We study the subalgebras and ideals of A which are preserved by the group action. We prove a structure theorem and two classification theorems for invariant subalgebras under suitable hypotheses on A. We illustrate these results in the case of compact connected Lie groups and give some other applications. We also classify invariant ideals. © 2002 Elsevier Science (USA).

The Evolving Accretion Disc In The Black Hole X-Ray Transient Xte J1859+226, R. I. Hynes, C. A. Haswell, S. Chaty, C. R. Shrader, W. Cui

Faculty Publications

We present HST, RXTE, and UKIRT observations of the broad-band spectra of the black hole X-ray transient XTE J1859+226 during the decline from its 1999-2000 outburst. Our UV spectra define the 2175-Å interstellar absorption feature very well and based on its strength we estimate E(B - V) = 0.58 ± 0.12. Hence we deredden our spectra and follow the evolution of the spectral energy distribution on the decline from outburst. We find that the UV and optical data, and the X-ray thermal component when detectable, can be fitted with a simple blackbody model of an accretion disc heated by internal …

First Observation Of The Drip Line Nucleus 140Dy: Identification Of A 7 Μs K Isomer Populating The Ground State Band, W. Królas, R. Grzywacz, K. P. Rykaczewski, J. C. Batchelder, C. R. Bingham, C. J.

A new 7 μs isomer in the drip line nucleus 140Dy was selected from the products of the 54Fe (315 MeV) + 92Mo reaction by a recoil mass spectrometer and studied with recoil-delayed γ-γ coincidences. Five cascading γ transitions were interpreted as the decay of an Iπ = 8- {ν9/2-[514]⊗ ν7/2+[404]} Kisomer (T 1/2 = 7.0(5) μs) via the ground-state band. The probability of proton emission from 141Ho to the 0+ ground state and to the 2+ excited state in 140Dy is discussed.
