Murderous Historian: Henry Adams, Modernity, And The Problem Of Subjectivity. (Volumes I And Ii)., Martha Moseley Regalis Jan 1994

Murderous Historian: Henry Adams, Modernity, And The Problem Of Subjectivity. (Volumes I And Ii)., Martha Moseley Regalis

LSU Historical Dissertations and Theses

This study traces Henry Adams's evolution from an enlightenment historian to a prescient postmodern theorist, and explores how he came to regard his own intellectual history as paradigmatic of the arc of subjectivity in the West from the Middle Ages to Nietzsche and Bergson. Adams was a self-conscious philosophical nominalist, and he believed that his radical doubts about the capacity of language for embodying meaning had their origin in medieval nominalism. Adams found the seeds of modernity and the problem of subjectivity which were the focus of his own musings on the nature of the self and history in Abelard …

May I Speak? A Hermeneutic Conversation Of Secondary Students' Experiences Of Curriculum., Kathryn M. Benson Jan 1994

May I Speak? A Hermeneutic Conversation Of Secondary Students' Experiences Of Curriculum., Kathryn M. Benson

LSU Historical Dissertations and Theses

The purpose of this study is to allow for a phenomenological, hermeneutic treatment of students' experiences of curriculum. The foci of this study are to stake a claim for the students' situated positions within educational research and to provide spaces within academic research where students' voices might be heard concerning their experiences of curriculum. After posing the problem of a lack of students' perspectives in educational research, I present the study's methodology: a blending of Gadamer's philosophical hermeneutics and van Manen's hermeneutic phenomenology. Terms which seem salient to the study are as follows: silence, voice, conversation, and experience. Categorical thematic …

The Rhetoric Of The Organizational Saga: A Fantasy Theme Analysis Of The Organizational Communication Culture Of The Louisiana State Police., Brookie Ann Allphin Jan 1994

The Rhetoric Of The Organizational Saga: A Fantasy Theme Analysis Of The Organizational Communication Culture Of The Louisiana State Police., Brookie Ann Allphin

LSU Historical Dissertations and Theses

This dissertation is a fantasy theme analysis of the organizational communication culture of the Louisiana State Police. This study interprets the rhetorical function of the organizational sagas of State Police. State Police has a distinct history aligned with Louisiana Politics. In 1937, General Louis F. Guerre, the first superintendent, envisioned a new State Police, immune from political pressures, "soldiers of the law in the first line of defense for society." The symbolic persona of LSP has survived through fifty-six years of politics and policing as the state's ranking law enforcement agency. As participant observer, the researcher gathered communication data and …

Use Of Uncertainty Methodology In Identification And Classification Of Soils Based Upon Cpt., Zhongjie Zhang Jan 1994

Use Of Uncertainty Methodology In Identification And Classification Of Soils Based Upon Cpt., Zhongjie Zhang

LSU Historical Dissertations and Theses

The current Cone Penetration Test (CPT) soil engineering classifications have two kinds of uncertainties: randomness and fuzziness. Research indicates that possible solutions to these uncertainties can only be worked out through modeling them. Therefore, a systematic investigation is performed and some preparative tasks are done in advance. First, an efficient soil classification index, U, is defined and several CPT soil classification charts are simplified accordingly. Second, a moving window approach based upon an Intraclass Correlation Coefficient (ICC) to determine normal soil behavior units is adopted so that a correlation between soil types and soil behavior units can be established. Based …

"Rag-Tag And Bob-Ends Of Old Stories": Biblical Intertextuality In Faulkner, Hurston, Wright, And O'Connor., Timothy Paul Caron Jan 1994

"Rag-Tag And Bob-Ends Of Old Stories": Biblical Intertextuality In Faulkner, Hurston, Wright, And O'Connor., Timothy Paul Caron

LSU Historical Dissertations and Theses

Liqht in August, Moses, Man of the Mountain, Uncle Tom's Children, and Wise Blood all borrow from the South's religious traditions. Recognizing the authority given to the Book, Faulkner, Hurston, Wright, and O'Connor invoke and re-read its central stories, characters, and tropes in order to voice their individual contributions to the South's intra-cultural conversation on race. In various ways, each work claims the necessity of the South to revitalize its practice of biblical interpretation. All of these texts comment upon the South's racial struggles over exactly how the Bible was to be interpreted: is it a book to aid in …

Inference For Unreplicated Factorial And Fractional Factorial Designs., William J. Kasperski Jan 1994

Inference For Unreplicated Factorial And Fractional Factorial Designs., William J. Kasperski

LSU Historical Dissertations and Theses

The ability to determine which factors significantly affect a product or process can help to improve its quality. Usually there are many factors to be considered initially, but a limited amount of time and money, so it is important to screen the numerous factors with a limited number of experimental trials. In this situation, unreplicated factorial and fractional factorial designs are often used, but because these experiments are unreplicated they do not possess a formal estimate of the experimental error variance. Several methods have been proposed by Daniel, Box and Meyer, Benski, Lenth, and Schneider, Kasperski, and Weissfeld to determine …

Investigations On Insecticide Resistance In Tobacco Budworm, Heliothis Virescens (F.), And Boll Weevil, Anthonomus Grandis Grandis Boheman, In The Mid-South., Scott Hamilton Martin

LSU Historical Dissertations and Theses

Topical bioassays were conducted in 1991 to develop dose-mortality lines for the LSU laboratory reference colony (LSU-LAB) and field-collected colonies of tobacco budworm, Heliothis virescens (F.), from Louisiana, Mississippi and Texas. Field-collected colonies exhibited resistance to cypermethrin (1-41x), profenofos and sulprofos (1-8x), methomyl (2-6x) and no resistance to endosulfan compared to the LSU-LAB colony. Diagnostic dose bioassays were developed to facilitate rapid testing of field-collected colonies for resistance to insecticides. These diagnostic dose bioassays were conducted in 1992 and 1993 on the LSU-LAB colony, a North Carolina laboratory reference colony and field-collected colonies from Louisiana, Oklahoma and Texas.

The Development And Evaluation Of Impedance Technology To Determine The Quality Of Shrimp And Catfish., Patti Lynn Wiese Lehigh Jan 1994

The Development And Evaluation Of Impedance Technology To Determine The Quality Of Shrimp And Catfish., Patti Lynn Wiese Lehigh

LSU Historical Dissertations and Theses

Impedance technology is currently used as a measurement of microbial activity. The purpose of the current study was to determine the feasibility of utilizing impedance technology to evaluate the quality of white shrimp (marine species) and channel catfish (freshwater species). Impedance analysis measurements (I-values) of raw shrimp increased for samples stored at 5, 25, and 35$\sp\circ$C; however, control samples stored at $-$20$\sp\circ$C displayed no significant changes in I-values. I-values from thermally processed shrimp had no direct relationship with odor scores, increased storage time, or increased storage temperature. It was concluded that while impedance measurements were able to indicate the degree …

Titanocene/Dna Binding And The Synthesis And Characterization Of Bridged Cyclopentadienes For The Preparation Of Novel Titanocenes., Tamara Renee Schaller

LSU Historical Dissertations and Theses

Titanocene dichloride, a potent antitumor agent, forms a DNA-titanium adduct with Salmon Sperm DNA in 10 mM sodium perchlorate solutions ranging from pH 5 to 8.5. At physiological pH, titanocene dichloride undergoes base catalyzed hydrolysis in which the cyclopentadienyl ligands are susceptible to substitution. In chapter one of this dissertation the results of inductively coupled plasma and scintillation counting analysis of the DNA-titanium adduct formed by in vitro treatment of a DNA solution with tritiated titanocene dichloride indicate the formation of a DNA-Cp$\sb2$Ti adduct at pH 5.3 and a DNA-CpTi adduct at pH 7.0. Titanocenes prepared from bridged cyclopentadienyl ligands …

Employer Recruitment And Job Matching Theories: The Effects Of Informal Recruiting Practices On Racial And Gender Job Composition., Frederick Carson Mencken Jan 1994

Employer Recruitment And Job Matching Theories: The Effects Of Informal Recruiting Practices On Racial And Gender Job Composition., Frederick Carson Mencken

LSU Historical Dissertations and Theses

This dissertation analyzes the effects of employer recruiting practices on the gender and racial composition of jobs. Using the Metropolitan Employer-Employee Survey, I examine how the structural characteristics of organizations, occupations, industries and jobs affect the manner in which employers recruit for certain vacancies. The results show that employers use informal recruitment techniques, such as recruitment through professional colleagues and business associates, to recruit for executive/managerial, professional and other white-collar occupations. Employers use formal recruiting techniques for jobs in large establishments, in government agencies, and lower-level white-collar jobs. The dissertation addresses the link between recruitment practices and the gender and …

The Legacy Of America's "Forgotten Warriors:" An Analysis Of Dysfunctional Relational Communication Among Vietnam Combat Veterans Exhibiting Posttraumatic Stress Disorder Symptomatology., Jack Eugene Rogers Jan 1994

The Legacy Of America's "Forgotten Warriors:" An Analysis Of Dysfunctional Relational Communication Among Vietnam Combat Veterans Exhibiting Posttraumatic Stress Disorder Symptomatology., Jack Eugene Rogers

LSU Historical Dissertations and Theses

The literature has long reported the atypical stress-producing characteristics of the Vietnam conflict. For veterans still suffering from the psychological and emotional "fall-out" of war-related anxiety, one long-term adjustment dysfunction is the difficulty PTSD-positive veterans experience in sustaining successful interpersonal relationships. Competent dyadic communication plays a critical role in engendering positive relational trajectories. This study investigated the hypothesis that posttraumatic stress disorder would exhibit a correlational relationship with the relational communication topoi of intimacy and dominance/control. A cross-regional sample of 218 PTSD-positive veterans and their relational partners provided data. Scale construction and validation was achieved through orthogonal factor analysis with …

The Stylistic Mechanics Of Implicitness: Entailment, Presupposition, And Implicature In The Work Of Ernest Hemingway And Tim O'Brien., Donna Glee Williams Jan 1994

The Stylistic Mechanics Of Implicitness: Entailment, Presupposition, And Implicature In The Work Of Ernest Hemingway And Tim O'Brien., Donna Glee Williams

LSU Historical Dissertations and Theses

The discipline of linguistics has identified three patterns through which unstated information may be conveyed: entailment, presupposition, and implicature. Using these theoretical constructs, analysts may determine systematically how propositions which are never asserted may nonetheless be communicated. In the old writers' maxim "Show me; don't tell me," "showing" corresponds to implicit communication of unstated material, while "telling" corresponds to the overt assertion of the proposition of interest. Examination of texts by Hemingway and O'Brien reveals carefully controlled use of the linguistic strategies of implicitness to suspend meaning between and behind the fixed points of the words on the page. This …

Self-Diffusion Of Semiflexible Rod-Like Poly-Gamma-Benzyl-Alpha, L-Glutamate In Dilute And Nondilute Isotropic Solutions., Zimei Bu

LSU Historical Dissertations and Theses

The self-diffusion coefficient (D$\sb{\rm s}$) of fluorescent dye labeled poly-$\gamma$-benzyl-L-glutamates (LPBLG) in pyridine solutions was measured by fluorescence photobleaching recovery (FPR). Intrinsic viscosity and static light scattering measurements showed that the LPBLGs did not aggregate in pyridine and that the rod structure of LPBLG was not perturbed by labeling. The measured concentrations spanned from dilute to the most concentrated isotropic solutions, and the axial ratios from 7 to 80 (M$\sb{\rm W}$ ranged from 20 000 to 232 000). The objective of this FPR study was to focus directly on the translational diffusion of a single LPBLG molecule in the absence …

LSU Historical Dissertations and Theses

Field strains of soybean looper, Pseudoplusia includens (Walker), from Louisiana, Texas, and Puerto Rico were tested for permethrin synergism by piperonyl butoxide (PB) and S,S,S tributylphosphorotrithioate (DEF). Resistance was completely suppressed by 10 $\mu$g PB/larva in strains from Louisiana with 2.7 to 14.1-fold resistance. The Texas strain was 14.8-fold resistant and permethrin toxicity was increased 8.6-fold by PB. The Puerto Rico strain was highly resistant to permethrin (426.6-fold) and PB increased permethrin toxicity only 4.6 and 7.5-fold, respectively, at 10 and 20 $\mu$g/larva. No significant synergism resulted from DEF treatment in any of the strains tested. In field trials, efficacy …

A Comparative Study Of The Oral Language Of Students In Basal-Based And Whole Language Kindergartens., Joan H. Lucille Benedict Jan 1994

A Comparative Study Of The Oral Language Of Students In Basal-Based And Whole Language Kindergartens., Joan H. Lucille Benedict

LSU Historical Dissertations and Theses

Concern has existed for several years over the classroom practices relating to the "whole language" approach as opposed to the "basal-based" approach relative to literacy development, especially with respect to the appropriateness of each method for use with minority and lower socioeconomic groups of children entering kindergarten. This study describes the oral language of both African American and European American kindergarten children from low and middle socioeconomic status families who are attending public school kindergartens, one using whole language and one a basal-based approach. The language during centertime of seventeen children from these two classrooms was audiotaped using wireless microphones …

Promoter Analysis Of A Rice Seed Storage Protein Glutelin Gene And Expression Of Bean 7s Seed Storage Protein Beta-Phaseolin In Transgenic Rice Plants., Zhenwei Zheng

LSU Historical Dissertations and Theses

It was demonstrated, using a homologous transgenic rice system, $5\sp\prime$ distal and proximal cis-acting transcriptional regulatory elements were required for developmental control of a rice seed storage protein glutelin (Gt1) gene. The functional importance of proximal elements in the context of the 1.8 kb promoter was demonstrated by single substitution mutations in the TATA box ($-$28/$-$23), AACA motif ($-$73/$-$61), and protein-binding Boxes I ($-$103/$-$86), II ($-$124/$-$110), III ($-$175/$-$158), and IV ($-$200/$-$217). A simultaneous mutation of five protein-binding sites ($-$410/$-$86) essentially eliminated the activity of the 1.8 kb promoter. To understand the function of the $5\sp\prime$ distal cis-acting upstream sequence, eighteen …

Three Essays On Derivative Securities., Paul Douglas Brockman Jan 1994

Three Essays On Derivative Securities., Paul Douglas Brockman

LSU Historical Dissertations and Theses

The purpose of this dessertation is to analyze three issues related to the pricing of derivative securities. The first issue deals with options pricing and stock return volatility. If stock return volatility is a stochastic process, as opposed to deterministic process, then the present form of commonly-used option pricing models is misspecified and arbitrage-based arguments are invalid. Since stochastic volatility option models are considerably more complex than their deterministic counterparts, it is essential to rule out all deterministic possibilities before accepting the necessity of stochastic models. The result of applying chaos methodology to over 62,000 intra-day implied volatility observations shows …

Eric Voegelin's Mystical Epistemology And Its Influence On Ethics And Politics., Charles Warren Burchfield Jan 1994

Eric Voegelin's Mystical Epistemology And Its Influence On Ethics And Politics., Charles Warren Burchfield

LSU Historical Dissertations and Theses

The primary purpose of this dissertation is to examine and analyze Eric Voegelin's theory of knowledge, and to see what implications it has on his theories of ethics and politics. The profundity of Voegelin's epistemological search and recovery is apparent when placed in the context of his disillusionment with and resistance to the dominant epistemology of his day, namely, positivism. Through a recovery and restoration of the symbolizations of classical and Christian philosophy, Voegelin searches for and finds experiential knowledge which is gained through faith in search of understanding (fides quaerens intellectum), which brings about a vision of the whole …

The Development Of Bridge Inspection Strategies Based On A Statistical Analysis Of Deterioration In Underwater Structures., Mark Deymond Fugler

LSU Historical Dissertations and Theses

A comprehensive statistical analysis was performed on the condition data generated by a statewide underwater inspection of bridges in Louisiana. The research defined pertinent underwater structural decay characteristics and established a method for establishing a bridge's propensity for underwater deterioration based upon those relevant factors. The inspection results were reviewed to ascertain the impact of human-bias on the consistency in the bridge condition ratings. Using a set of importance factors obtained through a questionnaire submitted to a group of inspectors, the fuzzy set theory was employed to assist in the removal of data incongruities. A combination of pure fuzzy set …

Electrophysiological Responses Of Olfactory Receptor And Bulb Neurons To Stimulus Mixtures And To Their Individual Components In The Channel Catfish, Ictalurus Punctatus., Jiesheng Kang Jan 1994

Electrophysiological Responses Of Olfactory Receptor And Bulb Neurons To Stimulus Mixtures And To Their Individual Components In The Channel Catfish, Ictalurus Punctatus., Jiesheng Kang

LSU Historical Dissertations and Theses

Both electro-olfactogram and integrated multiunit receptor responses of populations of olfactory receptor neurons (ORNs) clearly showed that responses to complex mixtures were predictable. Results demonstrated that receptor sites for basic and acidic amino acids, respectively, are independent from those for neutral amino acids and multiple receptor site types with highly overlapping specificities exist for amino acids within each group. Results also confirmed that one mechanism for synergism is the simultaneous activation of relatively independent receptor sites by the components in a mixture, and there was no evidence of mixture suppression. Single ORNs recorded in vivo responded to stimuli with either …
