The Congruence Extension Property, The Ideal Extension Property, And Ideal Semigroups., Karen Dommert Aucoin Jan 1993

The Congruence Extension Property, The Ideal Extension Property, And Ideal Semigroups., Karen Dommert Aucoin

LSU Historical Dissertations and Theses

A semigroup has the congruence extension property (CEP) provided that each congruence on each subsemigroup of S extends to a congruence on S. The ideal extension property (IEP) for semigroups is defined analogously. A characterization of commutative semigroups with IEP is given in terms of multiplicative conditions within and between the archimedean components of the semigroup. A similar characterization of commutative semigroups with CEP is sought. Toward this end, archimedean semigroups with CEP are characterized in terms of multiplicative structure and a number of necessary conditions on multiplication between the archimedean components of a commutative semigroup with CEP are established. …

Studies On Hepatitis A Virus: I. Expression Of Viral Capsid Peptides In Escherichia Coli And Their Application For An Immunoassay. Ii. Development Of An Assay For Viral Detection By Anti-Hav Antibodies., Luis Antonio Baez

LSU Historical Dissertations and Theses

A panel of eleven monoclonal antibodies of the IgG and IgM class were developed against the HM 175 strain of the Hepatitis A virus. Immunoglobulin specificity for the Hepatitis A virus was determined and the antibodies were applied toward the development of an antigen capture assay linked to a nucleic acid amplification step (RT-PCR), for detection of the Hepatitis A virus. The neutralizing mouse monoclonal antibody and a rabbit polyvalent serum were assessed as capture antibodies for the immunoaffinity stage of the assay. Fifty microliter microfuge tubes were coated with the capture antibody. Formalin inactivated HAV was diluted to concentrations …

Memory Bias And Body Image Disturbance In Normal Weight Body Dysphoric Women., Jeffrey Duane Baker Jan 1993

Memory Bias And Body Image Disturbance In Normal Weight Body Dysphoric Women., Jeffrey Duane Baker

LSU Historical Dissertations and Theses

Body dysphoria is common in the general population and is thought to be associated with the development of eating disorders. Few studies have examined the role of cognitive processes in normal weight body dysphoric women. This study proposed an associative memory model of body dysphoria. The model predicted an increased memory bias for negative body words and increased body image disturbance in high body dysphoric subjects induced to a depressive mood. Based on the proposed model of body dysphoria, high dysphoric subjects were also predicted to give more depressive/negative body word associates on a word association task. Finally, the Pathfinder …

Neo-Hamiltonian Republicans And Military Reform In The Progressive Era: 1898-1912., Ronald James Barr Jan 1993

Neo-Hamiltonian Republicans And Military Reform In The Progressive Era: 1898-1912., Ronald James Barr

LSU Historical Dissertations and Theses

The Spanish-American War changed the course of American history. In a few months the United States acquired a colonial empire and adopted a policy of overseas involvement that greatly altered future world events. The political victory of a few military reformers and politicians, who endorsed Social Darwinism, over those who upheld the ideas of Jefferson and Jackson, destroyed the international isolation of the American republic. No matter what successive political administrations claimed, they inherited substantial overseas commitments. The group that engineered this profound change in American foreign and defence policy were led by Elihu Root, John Hay, Leonard Wood, Alfred …

A Southern Social Ethic: Political Economy In The Nineteenth-Century South. Mississippi, 1840-1910. (Volumes I And Ii)., Bradley G. Bond Jan 1993

A Southern Social Ethic: Political Economy In The Nineteenth-Century South. Mississippi, 1840-1910. (Volumes I And Ii)., Bradley G. Bond

LSU Historical Dissertations and Theses

As a study of the southern social ethic, this work discusses some of the most lasting themes of southern historiography: race and class, continuity and discontinuity. The social ethic might best be defined as a collection of ideas, at times contradictory, that suggest southerners' concepts of life in a good republic, citizenship, and proper economic behavior. It also examines the reality of life in a rural state as it experienced the process of modernization. The first third of the dissertation offers a definition of the social ethic. Liberty and virtue, white southerners believed, inhered in all who avoided enslavement, the …

Peasant Subsistence In Northwestern Haiti: Geography, Cultural Ecology, And Rural Development., Edward Cameron Britton Jan 1993

Peasant Subsistence In Northwestern Haiti: Geography, Cultural Ecology, And Rural Development., Edward Cameron Britton

LSU Historical Dissertations and Theses

Geographers are challenged to explain "the why of where." This study grapples with "whys" of peasant subsistence in contemporary rural Haiti. Cultural ecology, one of the fundamental themes in cultural geography, examines the interplay between cultural traditions and the realities of subsistence in a given physical environment. Haitian cultural traditions derive from a rich melange of folkways from West Africa, Indian Middle America, and Western Europe. The land is semiarid and hilly in Northwestern Haiti, the poorest, driest, and most sparsely settled of Haiti's provinces. Crops and livestock betray traditional preferences in foodways, and reveal much about the constraints of …

An Exploration Of The Organizational Structure Of Instructional Supervision. (Volumes I And Ii)., Joseph Gerard Claudet Jan 1993

An Exploration Of The Organizational Structure Of Instructional Supervision. (Volumes I And Ii)., Joseph Gerard Claudet

LSU Historical Dissertations and Theses

This study explores the organizational nature of instructional supervision in schools. A conceptual model of the organizational/supervisory (O/S) structure and effects of school supervisory behaviors is presented. The model is based on an organizational conception of instructional supervision that views the variety of supervisory behaviors, interactions and decision making engaged in by school personnel as forming a unique supervisory subculture within the school organization. The model suggests that a school's overall O/S structure is determined through the complex interrelationship of an array of macro- and micro-level communicative elements or supervisory events. These macro- and micro-level elements are, in turn, influenced …

Wise Economies: Storytelling, Narrative Authority, And Brevity In The American Short Story, 1819-1980., Kirk Lee Curnutt Jan 1993

Wise Economies: Storytelling, Narrative Authority, And Brevity In The American Short Story, 1819-1980., Kirk Lee Curnutt

LSU Historical Dissertations and Theses

This study proposes a new way of measuring brevity in the American short story. Since Edgar Allan Poe's definition of the tale, literary criticism has looked to various structural features within the text to define the elements that distinguish the short story from other prose genres like the novel. I argue that brevity is an essential feature of storytelling and suggest that its perception is molded and shaped by several historical factors. The phrase "wise economy" offers two ways of thinking about the conciseness of the form: it evokes a history of rhetorical economy central to the formation of a …

The Comparative Effects Of A Cognitive Learning Strategy And Movement Sequence Feedback During Motor Skill Acquisition., David Michael Cutton Jan 1993

The Comparative Effects Of A Cognitive Learning Strategy And Movement Sequence Feedback During Motor Skill Acquisition., David Michael Cutton

LSU Historical Dissertations and Theses

The purpose of this study was to examine the effectiveness of an active, cognitive learning strategy and movement sequence feedback on learning the tennis forehand. Three experiments were conducted which involved manipulations of cognitive learning strategies and/or augmented, movement sequence feedback (AMSF). In Experiment 1 four groups of subjects (Advance Organizer (AO) strategy, Performer Self-Cueing (PSC) strategy, and two Control groups (differentiated by background)) performed 50 trials on 5 separate days in a pretest, posttest design, separated by 3 acquisition days. Subjects who used either strategy had significantly better outcome scores than the two Control groups. The PSC group's movement …

Specificity Of Chaperonin Groel Binding To The Precursor Of The Small Subunit Of Ribulose-1,5-Bisphosphate Carboxylase., Carmen Wheelock Dessauer Jan 1993

Specificity Of Chaperonin Groel Binding To The Precursor Of The Small Subunit Of Ribulose-1,5-Bisphosphate Carboxylase., Carmen Wheelock Dessauer

LSU Historical Dissertations and Theses

Although chaperonin-assisted protein folding has been studied in vitro by a number of investigators, the features of an unfolded or partially folded polypeptide that are recognized and bound by chaperonins are not known. I addressed this question using the precursor of the small subunit (pS) of ribulose-1,5-bisphosphate carboxylase as a model substrate for GroEL, the bacterial chaperonin. The precursor protein was expressed in E. coli as a C-terminal fusion to protein A. Protein A-pS (and any associated cellular proteins) was isolated by affinity chromatography. GroEL could be eluted from the fusion protein by ATP and either GroES or casein, consistent …

The Congruence Extension Property And Related Topics In Semigroups., Jill Ann Dumesnil Jan 1993

The Congruence Extension Property And Related Topics In Semigroups., Jill Ann Dumesnil

LSU Historical Dissertations and Theses

A semigroup has the congruence extension property (CEP) provided that each congruence on each subsemigroup can be extended to a congruence on the semi-group. This property, the ideal extension property (IEP), and other related concepts are studied from both an algebraic and a topological perspective in this work. A characterization of semigroups with CEP is given in terms of the lattice of congruences. A similar result is obtained for IEP. Semigroups in which the relation "is an ideal of" is transitive (t-semigroups) are explored. It is shown that each of CEP and IEP implies this condition and that these are …

Teachers' Collective Bargaining: Its Occurrence And Impact On Wages, Employment, And Expenditures In States Without Collective Bargaining Legislation., Malcolm Michael Duplantis Jan 1993

Teachers' Collective Bargaining: Its Occurrence And Impact On Wages, Employment, And Expenditures In States Without Collective Bargaining Legislation., Malcolm Michael Duplantis

LSU Historical Dissertations and Theses

This study analyzed the extent of teachers' unions activities in the eleven states without favorable collective bargaining legislation and the impact of collective bargaining agreements on teachers' wages, employment rates, and per-pupil expenditures. Specifically, school districts were examined in the six states which authorize, but do not require collective bargaining, and the five states which have no legislative provisions concerning collective bargaining for teachers. School districts were examined if student enrollment exceeded 10,000. A two-phased methodology was used to address the research questions. Phase 1 was a qualitative study which utilized data from a survey of school superintendents in selected …

Autobiography As Repetition In The Works Of Walker Percy., Edward Joseph Dupuy Jan 1993

Autobiography As Repetition In The Works Of Walker Percy., Edward Joseph Dupuy

LSU Historical Dissertations and Theses

While many critics have explored some connections between Walker Percy's work and the philosophies of Soren Kierkegaard and Martin Heidegger, none has examined that link in terms of autobiography and autobiographical theory. This study looks at both Percy's fiction and nonfiction in light of the category of repetition and its relation to autobiography. Following largely the work of William Spanos, the first chapter establishes a reading of autobiography as repetition--understood as inter esse, "being between" and concerned in time. It then discloses a link between such a view of autobiography and Percy's diagnostic use of the novel. The remainder of …

2,2',6,6'-Tetrasubstituted Diarylethynes: Models To Test Proximity And Position In Catalysis., Kevin Levon Evans Jan 1993

2,2',6,6'-Tetrasubstituted Diarylethynes: Models To Test Proximity And Position In Catalysis., Kevin Levon Evans

LSU Historical Dissertations and Theses

Enzymes exhibit extraordinary efficiency and specificity in catalysis. A source of the catalytic power observed in enzymes has been attributed to the ability of the enzyme-substrate complex to bring the substrate into close proximity to the catalytic groups with proper orientation for reaction. However, the contributions of proximity and of orientation to the origin of catalytic power have not been quantified. A series of tethered and untethered 2,2$\sp\prime,$6,6$\sp\prime$-tetrasubstituted diarylethynes have been proposed to study the effect of proximity of the catalytic group to the substrate on catalysis. The syntheses of the diarylethyne models require efficient procedures for the synthesis of …

Woven Words: A Semiology Of Clothing In Medieval Texts., Fernando Luis Figueroa Jan 1993

Woven Words: A Semiology Of Clothing In Medieval Texts., Fernando Luis Figueroa

LSU Historical Dissertations and Theses

Much criticism in medieval studies has focused on Chrisitan allegory and its dissemination through Middle English poetry. Using recent insights into the nature of allegory in its medieval context, this study offers a new means of understanding allegory as it appears in the work of Chaucer and the Pearl-poet. Which ideas of figurality actually informed the works of these poets? The investigation into the influence of medieval "textuality" on Chaucer and the Pearl-poet has overlooked the image of the "veil" in the Middle Ages. This study asserts that instead of being a "flat" image, the veil provides us with a …

Seed Dormancy In Red Rice (Oryza Sativa): Changes In Embryo Ph And Metabolism During The Dormancy-Breaking Process., Steven Footitt Jan 1993

Seed Dormancy In Red Rice (Oryza Sativa): Changes In Embryo Ph And Metabolism During The Dormancy-Breaking Process., Steven Footitt

LSU Historical Dissertations and Theses

Hydrated, dehulled, dormant seeds of red rice (Oryza sativa L.) were exposed to chemical treatments (nitrite, propionic acid, methyl propionate, propionaldehyde, and n-propanol) that saturate the dormancy-breaking response. Dormancy-breaking chemicals were (a) metabolized (n-propanol and propionate) by embryos in dormant seeds to weak acids; (b) decreased embryo pH; and (c) increased embryo (Fru 2,6-P$\sb2$) prior to dormancy-breaking. Embryo acidification, but not increased embryo (Fru 2,6-P$\sb2$), was associated with the chemical contact interval required for the onset of dormancy-breaking. During chemical contact, embryo (Fru 2,6-P$\sb2$) increased independent of dormancy-breaking and was inversely correlated with the elapsed time to 30% germination. On …

Discourses Of Maternity And The Postmodern Narrative: A Study Of Lessing, Walker, And Atwood., Janet J. Montelaro Jan 1993

Discourses Of Maternity And The Postmodern Narrative: A Study Of Lessing, Walker, And Atwood., Janet J. Montelaro

LSU Historical Dissertations and Theses

Doris Lessing's The Golden Notebook, Alice Walker's The Color Purple, and Margaret Atwood's The Handmaid's Tale are narrated by women whose social identities are partially constructed through activities traditionally associated with mothering. In each text, maternity signifies a biological event as well as the social, sexual, and material relations involved with pregnancy, childbirth, and the nurturing and rearing of children, activities which become grounds for investigating the politics of the body, of sexuality, and consequently, of gender relations. Maternity becomes politicized within the cultural contexts of each novel as maternal experience functions to produce both feminist and postmodernist critiques. In …

Caregiver Stress And Well-Being As A Function Of Multiple Roles., Gwendolyn Miller Moore Jan 1993

Caregiver Stress And Well-Being As A Function Of Multiple Roles., Gwendolyn Miller Moore

LSU Historical Dissertations and Theses

Predictors of caregiver psychological well-being, including depression, marital satisfaction, positive affect and negative affect were examined as a function of primary and secondary stress. Measures assessing these outcomes as well as role overload, inter-role conflict and care receiver impairment were administered to 77 female caregivers of dementia patients. A comparison group of 80 females was also included. Results demonstrated that noncaregivers experienced significantly higher positive affect than caregivers. In addition, differential mediating relationships were found between primary and secondary stressors contingent upon the type of outcome examined. More specifically, inter-role conflict mediated the relationship between work overload and both positive …

Geologic And Physical Processes At A Gulf Of Mexico Tidal Inlet, East Pass, Florida., Andrew Morang Jan 1993

Geologic And Physical Processes At A Gulf Of Mexico Tidal Inlet, East Pass, Florida., Andrew Morang

LSU Historical Dissertations and Theses

East Pass, a tidal inlet located in the Florida Panhandle between Pensacola and Panama City, connects Choctawhatchee Bay to the Gulf of Mexico. A three-phase model has been developed which describes the behavior of East Pass inlet during the last 120 years, based on wave, current, tide, bathymetric and shoreline data, and on historical records. The first phase (pre-1928) is of spit development and breaching. This phase covers the period when the pass was oriented in a northwest-southeast direction between Choctawhatchee Bay and the Gulf. From 1928 to 1968, the second phase was characterized by a stable throat position but …

Windows To Critical Thinking: Perspectives On Pedagogy In Henry James's "The Bostonians", Carson Mccullers's "The Heart Is A Lonely Hunter", And Frederick Douglass's "Narrative Of The Life Of Frederick Douglass, An American Slave"., James Thomas Mullane Jan 1993

Windows To Critical Thinking: Perspectives On Pedagogy In Henry James's "The Bostonians", Carson Mccullers's "The Heart Is A Lonely Hunter", And Frederick Douglass's "Narrative Of The Life Of Frederick Douglass, An American Slave"., James Thomas Mullane

LSU Historical Dissertations and Theses

Many times teachers restrict students to viewing literature through a single "preferred" window or from a rather small set of tiny windows, thus hindering their ability to think critically and make choices for themselves. It is my contention that our pedagogy should facilitate a "school of windows" in which students are offered many different vantage points from which to "see" literature--an environment which, instead of monologically conditioning them to accept content without criticism or question, dialogically allows them their own place and importance in active discourse. This study delineates the power that literature has to enable students to acquire these …

Circadian Neuroendocrine Regulation Of Scale Allograft Reactions In Gulf Killifish, Fundulus Grandis., Nicholas John Nevid Jan 1993

Circadian Neuroendocrine Regulation Of Scale Allograft Reactions In Gulf Killifish, Fundulus Grandis., Nicholas John Nevid

LSU Historical Dissertations and Theses

Reactions against scale allografts in gulf killifish were studied to examine circadian variation and neuroendocrine regulation of immune function. Although melanophores in autografts remain viable indefinitely, melanophores in scale allografts were broken down predominantly at night (12-h scotophases) regardless of the time of transplantation. Daily treatment with hormones or antagonists of neuroendocrine receptors altered the rhythm of melanophore breakdown when administered at light onset or light offset. Daily rhythms of immune activity may be a direct reflection of growth hormone levels and are entrained by exogenous cortisol treatment. Daily nonphotoperiodic environmental stimuli overrode photoperiodic entrainment of immune activity. Peak melanophore …

Factors Contributing To Resistance In Rice To The Rice Water Weevil, Lissorhoptrus Oryzophilus Kuschel., Francois Kouame N'Guessan Jan 1993

Factors Contributing To Resistance In Rice To The Rice Water Weevil, Lissorhoptrus Oryzophilus Kuschel., Francois Kouame N'Guessan

LSU Historical Dissertations and Theses

Studies were conducted in the field and greenhouse to identify sources of rice water weevil (Lissorhoptrus oryzophilus Kuschel) resistance in rice, Oryza sativa L., and determine the mechanisms of resistance. Rice lines of various sources, including breeding lines, somaclone lines and world collection lines, were evaluated. Tolerance was investigated using replicated insecticide treated and untreated plots in a split-plot design, and antibiosis and/or antixenosis were assessed using caged insect-infested plants in randomized block designs. Resistance predictors included rice water weevil larval populations, larval root pruning damage, plant height and grain yield. Anther culture lines 95-2836 and 95-3527, Louisiana breeding lines …

Attitude Formation And Development: An Investigation Of The Interrelationships Among Attitudinal Constructs And Their Resistance To Counterpersuasion., Melodie Ree Phillips Jan 1993

Attitude Formation And Development: An Investigation Of The Interrelationships Among Attitudinal Constructs And Their Resistance To Counterpersuasion., Melodie Ree Phillips

LSU Historical Dissertations and Theses

The study examined the resistance of attitudes to counterpersuasion using the Elaboration Likelihood Model as a framework for analysis. The ELM postulated the centrally formed attitudes are more resistant to counterpersuasion than peripherally formed attitudes. A negative publicity setting was used to introduce respondents to a longitudinal study of attitude formation and change. A model was developed hypothesizing the role of company and brand cognitions would be significant in the formation of attitudes and intentions in central processors. It was hypothesized that A$\sb{\rm Ad}$ would be the primary influence on company and brand attitudes for peripheral processors. A sample of …

Syntheses, Structures, And Characterizations Of 2,2',7,7'-Tetrasubstituted 1,1'-Ethynylenedinaphthalenes., Philippe Prince

LSU Historical Dissertations and Theses

In order to study intramolecular enzyme catalysis, chemical models have been designed to quantify the proximity and orientation effects which occur in carboxylate catalyzed hydrolyses. As part of this broader study, various 2,2$\sp\prime$,7,7$\sp\prime$-tetrasubstituted 1,1$\sp\prime$-ethynylenedinaphthalenes are synthesized from 2,7-dihydroxynaphthalene. Two different strategies are used to obtain the title compounds. The first strategy involves palladium-mediated couplings between electron-poor aryl iodides and electron-rich arylethynes and allows synthesis of unsymmetrical binaphthylethynes. The second approach couples two 2,7-disubstituted naphthalenes with tetrachlorocyclopropene in the presence of aluminum chloride, but only symmetrical binaphthylethynes are obtained. During the course of this work, a number of 1,2,7-trisubstituted naphthalenes, some …

Contributions Of Monoclonal Antibodies With Anti-Neural Cell Adhesion Molecule Like Activity To Peripheral Nerve Regeneration., Laura G. Remsen Jan 1993

Contributions Of Monoclonal Antibodies With Anti-Neural Cell Adhesion Molecule Like Activity To Peripheral Nerve Regeneration., Laura G. Remsen

LSU Historical Dissertations and Theses

Tubes containing monoclonal antibodies with anti-neural cell adhesion molecule (N-CAM)-like activity were applied to transected sciatic nerves to attempt to perturb the recovery of muscle function. Physiological recordings were used to estimate the return of function. The decline of implanted antibody over 28 days was estimated. No significant immune responses were detected in response to the implanted material. Electron microscopic and immunohistological analyses evaluated particular cellular disruptions in nerves due to the presence of these antibodies with anti-N-CAM like activity. Histological sections of fixed experimental nerves consistently revealed abnormal gaps between Schwann cells of regenerating nerves. This specific Schwann cell …

Origin Of A Coarse-Grained Shallow Marine Sandstone Complex: The Coniacian Tocito Sandstone, Northwestern New Mexico. (Volumes 1 And 2)., Gregory Wayne Riley Jan 1993

Origin Of A Coarse-Grained Shallow Marine Sandstone Complex: The Coniacian Tocito Sandstone, Northwestern New Mexico. (Volumes 1 And 2)., Gregory Wayne Riley

LSU Historical Dissertations and Theses

Study of the Coniacian Tocito Sandstone, one of the shale-encased, shallow marine sandstone complexes in the Cretaceous Western Interior Basin, indicates that transport of coarse sediment to distal marine locations was accomplished by an increase in the efficiency of the marine dispersal system (tidal currents). Enhanced tidal currents were a consequence of bathymetric variations formed by uplifts along the pre-existing Four Corners Lineament system. The Tocito Sandstone forms an entirely marine, progradational-transgressive sequence and overlies an unconformity localized along uplifted submarine highs. The lower progradational strata represent the marine portion of a tide-dominated delta that prograded into a tectonically-created "embayment", …

Christianity And Social Power In The Works Of John Arden, British Dramatist., Donald Travis Sandley Jan 1993

Christianity And Social Power In The Works Of John Arden, British Dramatist., Donald Travis Sandley

LSU Historical Dissertations and Theses

This dissertation examines the subject of political and social power in the plays and prose of John Arden and selected works co-authored by Arden and his wife, Margaretta D'Arcy. Particular focus is given to the institution of Christianity and how it may either be used as a tool for the maintenance of established authority or as a vehicle for rebellion. Arden's collected essays, along with a personal interview conducted in August of 1990, provide the starting point for a discussion of four specific works, pieces in which Arden most closely explores the political involvement of Christianity. These four works, The …

The Interrelationships Of Rotylenchulus Reniformis Linford And Oliveira With Rhizoctonia Solani Kuhn On Cotton., Ambalavanan Sankaralingam Jan 1993

The Interrelationships Of Rotylenchulus Reniformis Linford And Oliveira With Rhizoctonia Solani Kuhn On Cotton., Ambalavanan Sankaralingam

LSU Historical Dissertations and Theses

The interrelationships between the reniform nematode, Rotylenchulus reniformis Linford and Oliveira, and the fungus Rhizoctonia solani Kuhn were studied on cotton (Gossypium hirsutum L.). Parasitism of cotton seedlings by R. solani resulted in enhanced reproduction of R. reniformis. In the presence of the fungus, there was increased egg production by the nematode which resulted in augmented soil population density. Enhanced reproduction of the nematode in the presence of the fungus was consistent across isolates of R. solani, populations and inoculum levels of R. reniformis, and cotton cultivars. The nematode did not influence the severity of seedling blight disease. At 90 …
