Group Automorphisms And The Decomposition Of Plancherel Measures, David Slay Jan 2002

Group Automorphisms And The Decomposition Of Plancherel Measures, David Slay

LSU Doctoral Dissertations

In this paper, a natural action of the automorphisms of a group on the space of irreducible unitary representations is used to decompose the Plancherel measure on the dual space as an integral of measures on homogeneous spaces. Explicit decompositions are obtained for the cases of free 2 and 3-step nilpotent Lie groups. These results are obtained using direct integral decompositions, induced representations, the Mackey Machine, and measure theory on homogeneous spaces.

The Role Of Attention In Affect Perception: An Examination Of Mirsky's Four Factor Model Of Attention In Chronic Schizophrenia, Dennis R. Combs Jan 2002

The Role Of Attention In Affect Perception: An Examination Of Mirsky's Four Factor Model Of Attention In Chronic Schizophrenia, Dennis R. Combs

LSU Doctoral Dissertations

Attention and affect perception was examined in a sample of sixty-five persons with chronic schizophrenia. Attentional skills may be related to deficits in affect perception due to a lack of attention to important information contained in the face. Deficits of this sort can dramatically inhibit appropriate social functioning. However, there is a lack of empirical research on this topic. Mirsky's four factor model of attention was used as a broad-based assessment of attentional functioning. The four factors of attention were: 1) Focus-Execute, 2) Encode, 3) Sustain, and 4) Shift. Neuropsychological measures reflective of attentional factor were administered. In this study, …

Pleasure Principles: The Social Construction Of Gambling And Sex Addiction Treatment, M. Kelly James Jan 2002

Pleasure Principles: The Social Construction Of Gambling And Sex Addiction Treatment, M. Kelly James

LSU Doctoral Dissertations

The transformation of behavior into deviance requires many players, individuals, and institutions invested in the social construction process and its outcomes. Although considered private recreational matters by some, gambling and having sex are gaining spotlight in the addiction arena. With the growing availability of casino entertainment, lotteries, OTB venues, prostitution, internet pornography, and 900 numbers, gambling and sex are interpreted, labeled, and treated by addiction recovery specialists. Using ethnographic methods and face-to-face interviews, I explore a southern community’s institutions and practitioners providing services to gambling and sex addicts. I examine the community’s discourse and its methods for defining and controlling …

It Came From Outer Space: The Virus, Cultural Anxiety, And Speculative Fiction, Anne-Marie Thomas Jan 2002

It Came From Outer Space: The Virus, Cultural Anxiety, And Speculative Fiction, Anne-Marie Thomas

LSU Doctoral Dissertations

This study seeks to explore and interrogate the “viral reality” of the 1990s, in which the virus, heavily indebted to representations of AIDS for its metaphorical power, emerged as a prominent agent in science and popular culture. What becomes apparent in both fictional and non-fictional texts of this era, however, is that the designation of “virus” transcends specific and material viral phenomena, making the virus itself a touchstone for modern preoccupations with self and other. As constituted by the human body’s interaction with pathogenic agents, the binary of self and other may be deconstructed by an interrogation of the virus …

Prelude To A Text : The Autobiography Of Abdelkebir Khatibi, Ruth Louise Gaertner Jan 2002

Prelude To A Text : The Autobiography Of Abdelkebir Khatibi, Ruth Louise Gaertner

LSU Doctoral Dissertations

This study of Abdelkebir Khatibi’s autobiography, La Mémoire tatouée, addresses two specific questions with respect to autobiography: What does this autobiography tell us about autobiography in general and about its own status as autobiography? What is the relationship between Khatibi’s autobiography and his other more well-known texts? Chapter One focuses on questions of autobiography and how this text challenges generic classification and definition. The analysis in this chapter focuses on a consideration of form and innovation, the multiplicity of the autobiographical subject, and questions of completeness, accuracy and memory in the creation of autobiography. Chapter Two begins with the idea …

Nonlinear Dynamics In Nuclear Structure, Guergana Stoianova Stoitcheva Jan 2002

Nonlinear Dynamics In Nuclear Structure, Guergana Stoianova Stoitcheva

LSU Doctoral Dissertations

New collective coordinates that describe the deformation of atomic nuclei in terms of solitary waves (rotons) that are solutions of an underlying nonlinear liquid drop dynamics are introduced. The rotons, which are highly localized surface excitations, are shown to be intelligent states of an underlying angular momentum algebra, and furthermore, to adiabatically decouple from the rotational motion of the nucleus. An expansion of the roton profile in terms of surface multipoles shows that although the quadrupole mode (&lambda= 2) dominates, there are significant contributions from other even multipoles with &lambda= 4, 6, 8, etc. The picture of nuclear deformation that …

Screening And Characterization Of Pathogenic Fungi For Possible Control Of Coptotermes Formosanus, Jianzhong Sun Jan 2002

Screening And Characterization Of Pathogenic Fungi For Possible Control Of Coptotermes Formosanus, Jianzhong Sun

LSU Doctoral Dissertations

Coptotermes formosanus was used as “bait” to isolate pathogenic fungi from soil. Fifteen pathogenic fungal isolates were obtained, all either Metarhizium anisopliae (six isolates) or Beauveria bassiana (nine isolates). There were no differences in numbers of fungal isolates from the three sampling locations. However, significantly more isolates were found in woodlands (eleven) than in pastures (four). Median lethal doses (LD50s) of these fungal species to C. formosanus were interspersed, indicating that fungal isolates rather than species had the greatest effect on virulence. In vitro growth characteristics were significantly correlated with virulence against termites, suggesting that fungal virulence might be predicted …

Multidemensional Goals Of Farmers In The Beef Cattle An Dairy Industries, Aydin Basarir Jan 2002

Multidemensional Goals Of Farmers In The Beef Cattle An Dairy Industries, Aydin Basarir

LSU Doctoral Dissertations

Farm firm decision making processes have long been of concern to agricultural economists. The concept of maximizing utility rather than profit is an important concept in multidimensional goal research. The prevalence of low or negative net returns in Louisiana beef and dairy production leads to the hypothesis that goals other than profit maximization compete strongly in producers' decisions. The objective of this study is to determine the hierarchy of goals that motivate beef and dairy producers and evaluate them in a multi-dimensional framework. Seven goals were evaluated in producer decision making: Maintain and Conserve Land, Maximize Profit, Increase Farm Size, …

Feedback Seeking In Customer Service Relationships, Aletta Machell Barnard Jan 2002

Feedback Seeking In Customer Service Relationships, Aletta Machell Barnard

LSU Doctoral Dissertations

With the shift to a service economy (Cascio, 1995), customer service effectiveness is a critical measure of success for service firms. In service relationships, where a single employee may be the only point of contact for customers, monitoring service effectiveness becomes incumbent upon the employees delivering the service (i.e., boundary spanners). The purpose of this study was to provide an investigation into service effectiveness (i.e., customer satisfaction and repatronage and word-of-mouth intentions) in service relationships. Specifically, boundary spanners' perceived organizational support (POS) was proposed to impact customer satisfaction through its impact on feedback seeking behaviors (i.e., direct inquiry, monitoring, positive …

Racks, Quandles And Virtual Knots, Victor Samuel Nelson Jan 2002

Racks, Quandles And Virtual Knots, Victor Samuel Nelson

LSU Doctoral Dissertations

We begin with a brief survey of the theory of virtual knots, which was announced in 1996 by Kauffman. This leads naturally to the subject of quandles and quandle homology, which we also briefly introduce. Chapter 2 contains a proof in terms of Gauss diagrams that the forbidden moves unknot virtual knots. This chapter includes material which has appeared in the Journal of Knot Theory and its Ramifications and is reprinted here by permission of World Scientific Publishing. In chapter 3 (cowritten with my advisor R.A.Litherland) we confirm a conjecture of J.S.Carter et.al. that the long exact sequence in rack …

Development Of Diagnostic Tools For Detecting Expression Of Resistance-Associated Esterases In The Tobacco Budworm, Heliothis Virescens (F.), Huazhang Huang Jan 2002

Development Of Diagnostic Tools For Detecting Expression Of Resistance-Associated Esterases In The Tobacco Budworm, Heliothis Virescens (F.), Huazhang Huang

LSU Doctoral Dissertations

Esterase-based metabolic resistance was studied using biochemical and biological assays with organophosphate (OP)- and pyrethroid (PYR)- resistant tobacco budworms, Heliothis virescens. In biochemical assays, results suggest that: (1) esterase activities toward all substrates used were enhanced in both resistant strains compared with the susceptible strain, suggesting that esterases were involved in resistance; (2) esterase profiles differed depending on the strain and substrate used, and these differences were visualized by using native polyacrylamide gel electrophoresis; 3) esterase activities toward some pyrethroid substrates were significantly higher (P ≤ 0.01) in the PYR-R strain than those in the OP-R strain. These results suggest …

Effects Of Structural Marsh Management And Salinity On Sediments, Hydrology, Invertebrates, And Waterbirds In Marsh Ponds During Winter On The Gulf Coast Chenier Plain, Francois Bolduc Jan 2002

Effects Of Structural Marsh Management And Salinity On Sediments, Hydrology, Invertebrates, And Waterbirds In Marsh Ponds During Winter On The Gulf Coast Chenier Plain, Francois Bolduc

LSU Doctoral Dissertations

Compositions of wintering waterbird communities are dependent upon food accessibility (via water depth), biomasses and sizes of their invertebrate prey, which in turn are influenced by the hydrology and sediments of wetland habitats. The hydrology and sediments of marsh ponds on the Gulf Coast Chenier Plain probably are affected by structural marsh management (levees, water control structures and impoundments; SMM) and salinity; therefore, SMM and salinity ultimately may affect wintering waterbird communities. Accordingly, I measured sediment and hydrologic variables, biomasses and sizes of common aquatic invertebrates, and densities of common wintering waterbird species in ponds of impounded freshwater (IF), impounded …

Phylogeny Of Ericameria, Chrysothamnus And Related Genera (Asteraceae : Astereae) Based On Nuclear Ribosomal Dna Sequence Data, Roland P. Roberts Jan 2002

Phylogeny Of Ericameria, Chrysothamnus And Related Genera (Asteraceae : Astereae) Based On Nuclear Ribosomal Dna Sequence Data, Roland P. Roberts

LSU Doctoral Dissertations

Phylogenetic relationships and classification of Chrysothamnus, Ericameria, Xylothamia and related genera were investigated. The internal transcribed spacer and 3' external transcribed spacers (ITS and ETS) of the nuclear ribosomal (nr) DNA were analyzed separately and combined employing different optimality criteria. These analyses indicated that the previous classifications and hypotheses of relationships were not monophyletic. Chrysothamnus, Ericameria, Xylothamia, and related genera were placed in separate lineages irrespective of data set and optimality criteria. Chrysothamnus species, as traditionally delimited, were resolved in four, not necessarily closely related lineages affiliated with the Solidagininae. Previous sectional classification of Chrysothamnus based primarily on morphology was …

Critical Performative Pedagogy : Augusto Boal's Theatre Of The Oppressed In The English As A Second Language Classroom, Ross Mckeehen Louis Jan 2002

Critical Performative Pedagogy : Augusto Boal's Theatre Of The Oppressed In The English As A Second Language Classroom, Ross Mckeehen Louis

LSU Doctoral Dissertations

Performative pedagogy combines performance methods and theory with critical pedagogy in an effort to carry out the dual project of social critique and transformation. Performance offers an efficacious means of completing this project by privileging students’ historicized bodies, by implementing contingent classroom dialogue, and by exposing students to the value embedded in performance risk. In this study, I apply performative pedagogy to an English as a Second Language (ESL) context in response to its problematic pedagogical history. In particular, I argue that Augusto Boal’s Theatre of the Oppressed practice should be adapted as a method for doing performative ESL pedagogy. …

Superfetation In Beef Cattle, Joel Andrew Carter Jan 2002

Superfetation In Beef Cattle, Joel Andrew Carter

LSU Doctoral Dissertations

Although superfetation has been reported in cattle and other species, there is considerable skepticism as to its existence due to the lack of clear evidence in these reports. Other explanations such as embryonic diapause or differential growth of twins have been suggested as more accurate descriptions of the cases reported as superfetation. The hypothesis of this study is that if a viable pregnancy can ensure maternal recognition in cattle, an asynchronous embryo can develop in a more chronologically advanced uterine environment. The objective was to produce superfetation by (1) ovulation induction and artificial insemination (AI) of pregnant cows and (2) …

Extraction Of Physically-Realistic Pore Network Properties From Three-Dimensional Synchrotron Microtomography Images Of Unconsolidated Porous Media, Riyadh Ibrahim Al-Raoush Jan 2002

Extraction Of Physically-Realistic Pore Network Properties From Three-Dimensional Synchrotron Microtomography Images Of Unconsolidated Porous Media, Riyadh Ibrahim Al-Raoush

LSU Doctoral Dissertations

Algorithms were implemented to obtain high resolution three-dimensional images using synchrotron microtomography. Morphological algorithms were developed to extract physically-realistic pore-network structure from unconsolidated porous media systems imaged using synchrotron microtomography. The structure can be used to correlate pore-scale phenomena with the pore structure and can also be incorporated into a pore-network model to verify existing models, understand, or predict transport and flow processes and phenomena in complex porous media systems. The algorithms are based on the three-dimensional skeletonization of the pore space in the form of nodes connected to paths. Dilation algorithms were developed to generate inscribed spheres on the …

The Effects Of Strategic Corporate Philanthropy On Consumer Perceptions: An Experimental Assessment, Joe M. Ricks, Jr. Jan 2002

The Effects Of Strategic Corporate Philanthropy On Consumer Perceptions: An Experimental Assessment, Joe M. Ricks, Jr.

LSU Doctoral Dissertations

There are many objectives for corporate philanthropic activity beyond altruism. Financial gain, increased image, and thwarting negative publicity have been suggested as potential objectives for corporate giving. This dissertation develops a 2X2 classification schema as a framework for empirical investigation and managerial decision making. Additionally this dissertation examines current models of corporate philanthropy and develops a new model for the use of philanthropy in crisis management using stakeholder theory. Finally it presents experimental assessments of various types of philanthropy based on the classification schema. Philanthropic activity is assessed in the context of two controlled experiments. The first experiment examines the …

American Transcendental Vision: Emerson To Chaplin, Bill R. Scalia Jan 2002

American Transcendental Vision: Emerson To Chaplin, Bill R. Scalia

LSU Doctoral Dissertations

Ralph Waldo Emerson's publication of Nature in 1836 began a process of creating a new condition of American thinking, severed from European cultural and intellectual influences. The subsequent lectures The American Scholar and The Divinity School Address furthered this process, calling for an original American literature. Emerson's writing called consistently for poets with the ability to "see" past the material, apparent world to the world of eternal forms, which shaped nature in accordance with a divine moral imperative. Through this connection, man-as-poet would discover God in himself. In short, Emerson effectively transferred divinity from Unitarian doctrine to the individual, thereby …

Sediment Transport In Wind-Exposed Shallow, Vegetated Aquatic Systems, Allen Michael Teeter Jan 2002

Sediment Transport In Wind-Exposed Shallow, Vegetated Aquatic Systems, Allen Michael Teeter

LSU Doctoral Dissertations

Ecosystems with submersed vegetation are relatively shallow, physically stable and of moderate hydrodynamic energy. Submersed vegetation affect hydrodynamic friction for currents and waves resulting in increased overall frictional loss. Seagrasses shelter the sediment bed and reduce wind-wave resuspension. Bed sheltering factors were estimated from previous flume data on Laguna Madre seagrass species. Data from Laguna Madre indicate that total suspended material levels for bare areas are about an order of magnitude higher than some areas with submersed vegetation. Waves in Laguna Madre at depths less than 2 m were found to be smaller than those expected for the same non-dimensional …

Treatment Acceptability For The Prevention Of Obesity And Type 2 Diabetes Mellitus: The Effects Of Ethnicity, Weight, And Genetic Predisposition, Jean Marie Thaw Jan 2002

Treatment Acceptability For The Prevention Of Obesity And Type 2 Diabetes Mellitus: The Effects Of Ethnicity, Weight, And Genetic Predisposition, Jean Marie Thaw

LSU Doctoral Dissertations

Childhood obesity and its associated health consequences, such as type 2 diabetes mellitus, have dramatically increased over the past 30 years, with the greatest rise in African-American female children and adolescents. Although current prevention efforts show promising results, recent genetic findings may soon expand treatment strategies to include new medications and gene therapies specifically designed to prevent the development of obesity and type 2 diabetes in children. However, little is known about the acceptability of these interventions. The primary aim of this study was to examine the hypothetical impact of genetic knowledge on treatment acceptability in the prevention of childhood …

Nicholas Rowe's Writing Of Woman As Feminist Hero, Henry Herbert Sennett Jr. Jan 2002

Nicholas Rowe's Writing Of Woman As Feminist Hero, Henry Herbert Sennett Jr.

LSU Doctoral Dissertations

Nicholas Rowe was a playwright of some success during the first quarter of the eighteenth century in London. Rowe's importance to the theatre can be seen in his contribution to the development of strong female roles. He was part of that group of Whig writers who championed individual freedom, some rights for women, and a stronger parliament. It is my contention that Rowe was an "incipient" feminist and an innovator of theatrical practice through his use of the female protagonist. By "feminist" I mean that Rowe wrote about the plight of women in a society that afforded very few rights …
