Taxonomy And Biostratigraphy Of Sabinian Palynomorphs From The Wilcox Group (Paleocene-Eocene Epochs) Of Southwestern Louisiana., William Andrew Gregory Jr

LSU Historical Dissertations and Theses

Fifty conventional core samples from the Ragley Lumber #D1 well located in Allen Parish Louisiana (Sec 29, T5S, R7w) were analyzed for palynomorphs. The sediment was deposited during the Sabinian Provincial Stage (upper Paleocene-lower Eocene) in a marine environment as evidenced by the presence of in situ dinocysts and acritarchs in every sample. Terrigenous diversity of 129 taxa is comparable with marine palynomorph diversity of 46 taxa. Single sample diversity among the terrigenous palynomorph component (23-56 taxa) is comparable with single sample marine palynomorph diversity of 7-25 taxa. High terrigenous diversity intervals possibly indicate sourcing from multiple onshore environments or …

Process And Product In Prereferral Intervention: A Study Of Planning, Integrity, And Outcome., William Treen Mckee

LSU Historical Dissertations and Theses

The purpose of the study was to obtain data on the intervention planning processes engaged in by prereferral intervention teams, primarily, through a focus on the verbal processes of teacher and committee team member interactions. Teacher and committee participation in the prereferral intervention planning process was operationalized in terms of the frequency of teacher and committee verbal interactions, in terms of numbers of questions, responses, and initiated comments made by each, as well as teacher and committee speaking time. Results of analysis of these data revealed that teachers asked few questions and initiated relatively few comments in comparison with their …

Fluorescence Studies Of Phosphofructokinase From Bacillus Stearothermophilus., Soon-Jong Kim

LSU Historical Dissertations and Theses

Phosphofructokinase catalyzes the phosphorylation of $\beta$-fructose 6-phosphate (Fru-6-P) to $\beta$-fructose 1,6-bisphosphate. The first part of this dissertation shows that phosphofructokinase from Bacillus stearothermophilus (Bs-PFK) is a tetramer in the region pH 4.5-9.5 unlike the enzymes from mammalian sources, which exhibit association-dissociation reactions. Circular dichroism, steady-state fluorescence, and static and dynamic light scattering were used to study the conformational properties of the enzyme. Inactivation of the enzyme below pH 7.0 is not due to dissociation of the tetramer to dimers or monomers. In the second part, the fluorescence of the lone tryptophan was investigated by steady-state and time-resolved techniques. The decay …

The Effects Of Community Building Group Process Intervention Technique On Reading Performance Among Inmates In A Medium Security Prison., Robert Earl Roberts

LSU Historical Dissertations and Theses

A substantial body of research has shown that when students work together in groups and are rewarded based on the learning of all the groups members, they achieve consistently more than students who are in traditionally taught classes. The goal of this project was to test the effects of an innovative group process intervention technique on reading performance among a population of incarcerated adult males in a medium security prison in Louisiana. This model, referred to as "Community Building" (CBGP), has been utilized among other ways as an intervention technique to resolve organizational/personnel problems in private, business, university, and government …

The objectives of the dissertation were: (1) examine the relative influence of expectations, performance, and disconfirmation on satisfaction with professional services; (2) assess the relative influence of role based and non-role based dimensions of a professional service on satisfaction; (3) conceptualize and test the influence of consumer role constructs on satisfaction with professional services; and (4) examine the influence of involvement on satisfaction formation for professional services. Prior to seeing their doctor, one hundred and thirty-one orthopedic patients completed a questionnaire concerning their expectations for their own role, the doctor's role, the staff's role, and access mechanisms (non-role based dimensions …

Ultrafast Measurement Of Chemical Dynamics In The Condensed Phase Using Transient Vibrational Spectroscopy., Xiaobing Xu

LSU Historical Dissertations and Theses

Geminate recombination and vibrational energy relaxation of iodine in the condensed phase are investigated using picosecond transient Raman spectroscopy. The advantages of transient Raman in measuring vibrational energy relaxation and separating different reaction dynamics are demonstrated in this dissertation. Using transient Raman spectroscopy we have for the first time directly observed geminate recombination and vibrational energy relaxation of I$\sb2$ on both X and $A\sp\prime$ $\sp3\Pi\sb{2u}$ states. For the X state, energy relaxation from vibrational levels ranging from $\upsilon$ = 52 to $\upsilon$ = 1 have been observed. These levels correspond to absolute energies of 9,300 to 210 cm$\sp{-1}$ above the …

From Image To Identity: The Search For Authenticity In The Early Modernist Drama Of Maxwell Anderson, John Millington Synge, Federico Garcia Lorca And D. H. Lawrence., Janice Maria Oliver

LSU Historical Dissertations and Theses

Working roughly from the last decades of the nineteenth century into the first quarter of the twentieth, early modernist playwrights wrote in times which were dominated by realism, but when many still looked to poetic forms for expression. They shared artistic space with realist practitioners like Ibsen and Shaw on the one hand and poetic dramatists like Yeats and Eliot on the other. Interested in dramatizing the conflict between the private and the public selves, they faced a central problem of creating a form and attendant style that could bridge the gap between the individual and her/his environment, thus harmonizing …

A Study Of Metacognitive Skill As Influenced By Expressive Writing In College Introductory Algebra Classes., Naomi Barbara R Allen

LSU Historical Dissertations and Theses

The quality of mathematics education has become a major concern to mathematics educators. As a result, increased attention is being given to identifying the abilities that underlie competent performance. An outcome of this effort is an increasing belief that the development of metacognitive skills is an essential component of proficient mathematics performance. Writing, because it promotes reflective thinking, is believed to be the vehicle for this development. Writing in the mathematics classroom has previously received anecdotal support for its benefits to the learner and to the instructor, and limited quantitative benefits in problem-solving ability toward mathematics. This study examined the …

Le Vase Clos Proustien., Fabrice Igor Leroy

LSU Historical Dissertations and Theses

Proust's main novel, A la recherche du temps perdu, has been analyzed by Gilles Deleuze as the story of an experience of learning, the narrator's account of his gradual understanding of signs. This means that Proust's novel can be read as a continuous act of semiotic and social interpretation, and Claude Duchet's hypothesis that the systems of objects in a novel comprise a discourse of their own--a semiotic network within the text--can be a point of departure in the study of such signs, precisely of the detail as a dynamic structure. Such examination of the narration of fictional objects/signs belongs …

An Investigation Of The Relationship Between Input Type And Output Modification In English As A Second Language., Doris M. V Macdonald

LSU Historical Dissertations and Theses

Proposals regarding the beneficial effects of elements of modified interaction such as clarification requests and confirmation checks on SLA have been taken up by a number of researchers who have found evidence for their existence in discourse involving NNSs. These investigators have assumed that the presence of such interactional features are beneficial to language learning, yet there is little empirical evidence to support a causal relationship between the presence of these discourse features and change in the performance of the learner toward target-language forms. Furthermore, the potential benefits of modified interactions have not been evaluated against other classroom practices. This …

Oxidative Chemical Transformations Of Sesquiterpene Lactones., Howard Gordon Pentes

LSU Historical Dissertations and Theses

Oxidative chemical transformations of sesquiterpene lactones have been carried out to determine the effect these changes have on the biological activities of these derivatives. Vacuum liquid chromatography was used extensively to isolate the sesquiterpene lactones used for these synthetic transformations. Costunolide and dehydrocostuslactone were isolated from Costus Resinoid (Saussurea lappa) and dihydroparthenolide was isolated from Ambrosia artemisiifolia. The enolate oxidations of sesquiterpene lactones with oxygen and (camphorylsulfonyl)oxaziridine have been investigate. Enolate oxidations of sesquiterpene lactones with oxygen generate low yields of both 11$\alpha$- and 11$\beta$-hydroxylactones. The yields of enolate oxidations with (camphorylsulfonyl)oxaziridine are much improved (over oxygen) and the reaction …

Acoustic Topology Of Infant Proto-Syllables., James Robert Piroli

LSU Historical Dissertations and Theses

A corpus of CV-like proto-syllables was obtained from the archival recordings of three first-born infants, which were made in conjunction with earlier research on the acoustic and interactive aspects of infant language acquisition. Tokens were limited to proto-syllables with perceptual evidence of stop-like or glide-like qualities and an identifiable vowel. Following A/D sampling, measures of developmental change were made including F1/F2 steady states, transition durations, CV durations, maximum F2 velocities, F2 onset, fundamental frequency, shimmer, time-to-peak amplitude velocity, and time-to-peak F2 velocity within the transition. Contrary to expectations, the orderliness of the infant protosyllables was remarkable with few acoustic events …

Acquiring Vocabulary In A Foreign Language: Some Effects Of The Nature Of Instruction On The Knowledge And Use Of Words., Louise Stowell-Ruzicka

LSU Historical Dissertations and Theses

The purpose of this study was to examine the effect that the nature of instruction of French vocabulary words has on student knowledge and use of the words on five different measures: a definition recognition test, a cloze plus word bank test, a comprehension of a text containing the words, a writing assignment designed to elicit free use of these words and a test of overall reading proficiency. Eighty-one high school students in the second year course of French constituted three treatment groups: (1) traditional instruction where students were required to learn a list of 12 words paired with their …

The Federal Writers' Project's Mirror To America: The Florida Reflection., Pamela G. Bordelon

LSU Historical Dissertations and Theses

In the 1930s, the federal writers of the Works Progress Administration (WPA) plowed fertile new ground in American cultural scholarship. The writers were for the most part not professionals but white collar workers who had been dramatically rescued from unemployment by this government relief project. Like other New Deal relief agencies, the Writers' Project had been created more to make work than to do work. But by the end of the program, it had charted a nation and documented American life more comprehensively than any earlier effort had done. In Florida the federal writers produced a state guide, pioneered African-American …

Toward A Phenomenology Of Curriculum: The Work Of Max Van Manen And T. Tetsuo Aoki., Robert Kent Brown

LSU Historical Dissertations and Theses

In this study an attempt was made at understanding contemporary thought and application of phenomenological research to the field of curriculum and instruction. More specifically, it sought to identify a place and need for a methodology in curriculum research that exposes and clarifies the dynamics of pedagogy as a result of investigating the existential/ontological nature of pedagogical activity. In accomplishing this, the works of two major North American phenomenological curriculum theorists, T. Tetsuo Aoki and Max van Manen were examined. The work of these two significant contemporary curriculum theorists was used due to the international recognition their seminal phenomenologically oriented …

The Rhetoric Of Community Ritual: The Blessing Of The Shrimp Fleet At Chauvin, Louisiana., Barbara Elizabeth Gordon

LSU Historical Dissertations and Theses

This study examines the rhetorical functions of a community ritual, the blessing of the shrimp fleet at Chauvin, Louisiana. Chauvin is a Cajun community in south Louisiana. Their annual fleet blessing was instituted in the 1930's and continues today relatively unchanged. The author observed the preparations and performance of the blessing and boat parade and also interviewed community members about the blessing. The observations and interview transcriptions are the primary data used for analysis of the community discourse. Fantasy theme analysis is used to demonstrate the community's use of discourse to develop and maintain group hierarchy. The discourse reveals six …

An Investigation Of The Contribution Of Auditory-Grouping To The Comodulation Masking Release Effect., Patrick Wynn Rappold

LSU Historical Dissertations and Theses

The comodulation masking release (CMR) effect involves improved detection of a pure-tone signal in an amplitude-modulated (AM) masker by an addition of AM noise spectrally distant from the signal (i.e, outside the critical-band of the signal). The underpinning of CMR has been elusive, and despite many previous investigations of this phenomenon it remains unexplained. A plausible explanation of CMR involves perceptual, auditory-grouping of acoustic signals. The purpose of this project was to investigate an hypothesis based on auditory-grouping to explain the CMR effect. A series of three experiments was completed towards this purpose. In the first, signal detection thresholds were …

An Analysis Of Sequential Patterns Of Instruction In Piano Lessons., Donald Ray Speer

LSU Historical Dissertations and Theses

The purpose of this study was to investigate verbal behaviors of independent piano teachers in the setting of the private piano lesson. Twenty-five piano teachers from southeast Louisiana participated in the study. Teachers recorded the individual lessons of two students on audiotape. Verbatim transcripts were developed from a total of 47 recorded lessons. Transcripts were coded, identifying verbal behaviors with regard to components of sequential patterns established by Yarbrough and Price (1981, 1989). Verbal behaviors were analyzed for time spent in the categories of teacher presentation, student participation, and teacher reinforcement. Frequencies were obtained for the number of complete/correct, complete/incorrect, …

Effects Of A Whole Language Approach Using Authentic French Texts On Student Comprehension And Attitude., Colette Hood Stelly

LSU Historical Dissertations and Theses

The purpose of this study was to investigate the effects of a Whole Language Approach (WLA), using authentic French stories, on measures of listening and reading comprehension of fourth-year high school students of French, and on their attitudes to learning French, as opposed to students using customary textbook materials in a conventional teacher-centered classroom setting. This investigation comprised two components: (a) a quantitative component which statistically determined results on measures of listening, reading and attitude, and, (b) a qualitative component which reviewed classroom procedures through observation and interview. Analysis of variance on four separate posttests showed statistically significant differences in …

An Examination Of Auditor Changes Following Events Adversely Affecting External Auditor Credibility., Thomas E. Wilson Jr

LSU Historical Dissertations and Theses

This study examines auditor changes following events adversely affecting auditor credibility. Disciplinary actions against auditors by the Securities and Exchange Commission (SEC) are posited to be events damaging to auditor credibility. Agency theory and prior research are used to generate hypotheses about differences between client firms that switch auditors and client firms that do not switch auditors after an SEC action under Rule 2(e) against their auditor. A series of univariate and multivariate statistical tests are conducted on the sample firms. The sample is divided into a Switch group and a Non-Switch group. The sample as a whole is examined, …

An Investigation Of The Laryngeal System As The Resonance Source Of The Singer's Formant., Rebecca Finley Detweiler

LSU Historical Dissertations and Theses

Since its introduction in 1974, Johan Sundberg's model of the laryngeal system as the resonance source of the singer's formant (Fs) has gained wide acceptance. There have heretofore been no studies directly testing its validity in vivo. The purpose of this study was to undertake a direct test of that hypothesis, utilizing as subjects professional male singers trained in the western Classical tradition. The vocal behaviors of three trained singer-subjects were evaluated during modal and pulse register phonation via magnetic resonance imaging (M.R.I.), strobolaryngoscopy, and acoustical analysis. Dr. Sundberg's hypothesis rests upon two premises: (1) that the laryngeal system is …

Statistical Sophistication Of Research In Vocational Education., Chi Zhang

LSU Historical Dissertations and Theses

The purpose of this study was to determine the status of, and changes in, the statistical sophistication of research in vocational education in the 1980s. The study also explored relationships among statistical sophistication, problem area studied, and methodological strategy used in vocational education research. Data collected were obtained from 118 quantitative research reports randomly selected from the Journal of Vocational Education Research, the Journal of Agricultural Education, the Journal of Industrial Teacher Education, and the Journal of Vocational Home Economics Education published in the early (1980-1983) and the late 1980s (1986-89). The researcher developed instrument used in this study consisted …

A Multidimensional Career Commitment Measure (Mccm) Gauging Motivation To Work In One's Career Field., Kerry D. Carson

LSU Historical Dissertations and Theses

Past career commitment measures have been redundant with other work commitment measures or have been narrowly defined as professionalism. Blau's (1985) definition of career commitment as one's attitude towards one's vocation seems to most closely represent this construct. However, his measure has several problems including construct overlap with career withdrawal intentions. Because of a developmental lag in the career focus domain due to lack of established measures, the reported research constructed and tested a theoretically based measure of career commitment. Development of a new career commitment measure was based on London's (1983) theory of career motivation consisting of three theoretical …

An Examination Of Semiotic Theories Of Accounting Accruals., Harlan Lynn Etheridge

LSU Historical Dissertations and Theses

Two theories of accounting accruals form the core of this study. The theory of the functions of accounting accruals is induced from observation of accounting accruals. One type of accounting accrual reflects incomplete transactions under a system of cash receipts and cash disbursements. The function of these accruals is to convey data about economic events associated with incomplete cash transactions. These accruals are referred to as syntactically redundant accruals. The second type of accounting accrual presents messages in a different format than their counterparts in a system of cash receipts and cash disbursements. The function of these accruals is to …

The Rhodobacter Capsulatushema Region: Nucleotide Sequence And Functional Analysis., John Joseph Eckert

LSU Historical Dissertations and Theses

Most of the effort to elucidate the mechanism of oxygen-mediated regulation of tetrapyrrole biosynthesis in Rhodobacter capsulatus has focused on the first step in the biosynthetic pathway, the condensation of glycine with succinyl-CoA to form $\delta$-aminolevulinic acid. This reaction, in R. capsulatus, is catalyzed by $\delta$-aminolevulinate synthase, the product of the hemA gene. In order to facilitate further study of the hemA gene and its product, its nucleotide sequence was determined. The open reading frame encoding $\delta$-aminolevulinate synthase was determined to be 1,206 base pairs, encoding a 50,491 Da polypeptide of 401 amino acids. The DNA sequence was compared with …
