Making The Secular Sacred: An Analysis Of Linguistic Devices Used To Give Religious Perspective To Ordinary Events., Wayne Porter Gregory
Making The Secular Sacred: An Analysis Of Linguistic Devices Used To Give Religious Perspective To Ordinary Events., Wayne Porter Gregory
LSU Historical Dissertations and Theses
It has been suggested that human beings do not possess social reality so much as they actively and cooperatively construct it by means of language in interaction with others. The manipulation of symbols, the creation of inferences, the posturing of one's personal identity all work together to enable participants (both speakers and hearers) in a given speech event to create social reality and reaffirm and maintain their social relationships. In religious speech communities, like the one investigated in this study, participants seek to create a different kind of social reality--one that encompasses all of the individual and corporate experiences of …
Consumer Evaluation Of Product-Related Injuries: The Development And Empirical Testing Of A Behavioral Model Of The Product Liability Process., Bryce Mitchell Griffin
Consumer Evaluation Of Product-Related Injuries: The Development And Empirical Testing Of A Behavioral Model Of The Product Liability Process., Bryce Mitchell Griffin
LSU Historical Dissertations and Theses
This study strives to provide a better understanding of consumer evaluation of product liability cases. A model of consumer perceptions of the liability process, based predominantly on attribution theory, is developed and tested. The research first develops a general attributional model of the liability process, identifies relevant managerially-controllable dimensions of liability cases, and then tests consumer reaction to these factors utilizing experimental scenarios. The influence of several consumer-juror individual difference variables on the evaluation of liability cases is examined. In addition, potential mediators of the product liability process, including assessment of responsibility and affective evaluation of the plaintiff and defendant, …
Genetic And Systematic Study Of Viviparus Georgianus (Lea), A Freshwater Snail Species Complex., Masaya Katoh
Genetic And Systematic Study Of Viviparus Georgianus (Lea), A Freshwater Snail Species Complex., Masaya Katoh
LSU Historical Dissertations and Theses
Genetic and morphological variation were studied in a brooding (ovoviviparous) and morphologically variable freshwater snail (Viviparus georgianus (Lea)) in the southeastern United States. Eleven populations were clustered into three genetically isolated, allopatric species characterized by 7 to 15 diagnostic loci out of the 38 loci examined. These allopatric species were an eastern species (in eastern and southern Florida), a western species (in the Florida panhandle), and a central species in the Ochlockonee River. Nei's standard genetic distances between species were large (0.23-0.52) compared to within-species distances (0.00-0.06). Moreover, genetic distances between the Ochlockonee River species and other species were larger …
Three Essays On International Linkages Of The Korean Economy., Jai-Ki Lee
Three Essays On International Linkages Of The Korean Economy., Jai-Ki Lee
LSU Historical Dissertations and Theses
This dissertation consists of three essays. The first essay investigates whether the long run version of purchasing power parity (PPP) holds between Korea and its two major trading partners--the U.S. and Japan. The PPP relationship is examined using cointegration tests, which are proper to see the departures from the long run equilibrium. The second essay examines the empirical relationship between real exchange rates and interest rate differentials in the Korean-U.S. as well as the Korean-Japanese economies. This relationship is also examined using cointegration tests. The third essay examines how foreign economic shocks affect the Korean economy and analyzes the channels …
Control Of Phytoplankton Production In A Shallow, Turbid Estuary., Christopher J. Madden
Control Of Phytoplankton Production In A Shallow, Turbid Estuary., Christopher J. Madden
LSU Historical Dissertations and Theses
Water column primary production and chlorophyll were sampled between 1986-1991 in Fourleague Bay, LA, a shallow (1.5 m), river-dominated estuary that is extremely turbid (K$\sb{\rm D}$ = 4.44 m$\sp{-1}$). A high speed system for continuous flow-through sampling, Dataflow$\sp\copyright$, was developed to measure physicochemical variables and in vivo chlorophyll fluorescence at high temporal (1 s) and spatial (5 m) resolution from a small boat. Phytoplankton net primary production (NPP) was measured using an incubator which rotated bottles to prevent settling of the contents. NPP was found to be artificially increased by 10-83% at high light levels in non-rotated bottles when cells …
A Comparison Of Language And Graphic Products Of Students From Kindergarten Classrooms Differing In Developmental Appropriateness Of Instruction., Jean Germany Mosley
A Comparison Of Language And Graphic Products Of Students From Kindergarten Classrooms Differing In Developmental Appropriateness Of Instruction., Jean Germany Mosley
LSU Historical Dissertations and Theses
This study examines the ways in which kindergartners from more and less developmentally appropriate classrooms negotiate the process of graphic communication. Both quantitative and qualitative aspects of this process are examined. Eighty-one kindergarten children from four classrooms were asked to tell a story both verbally and graphically. They were encouraged to include drawing, writing, or both on their paper. Then they were asked to tell the story that they had produced graphically. The children were students in one of four classrooms from a single school system that were identified as: (a) most developmentally appropriate beliefs and practices; (b) developmentally appropriate …
Alternative Education And Social Change In Brazil: A History And Case Study., Maria De Lourdes Nunes
Alternative Education And Social Change In Brazil: A History And Case Study., Maria De Lourdes Nunes
LSU Historical Dissertations and Theses
In contrast to the elitism of the Brazilian formal education system are the efforts of educators at federal universities in promoting educational alternatives for the socioeconomically underprivileged population. Having reached its peak in the late 1950s and early 1960s and culminating with Paulo Freire's successful "conscientization" experiment in Angicos, educational alternatives were revitalized in the 1980s upon the nation's "return to democracy." Since then, Brazilian universities have committed themselves to contribute to the struggle for social transformation. Mission and objective statements of individual universities express their attitude towards active involvement in the process of alleviating educational and socioeconomic inequities which …

The diversity of students entering today's colleges and universities makes it increasingly important that educators, theorists and other scholars strive toward a fuller understanding of the life conditions of minority groups. This research is designed to provide insight into the processes, pressures and people that shape the lives of one particular minority group, the African American non-traditional, first generation college student. In this research, I examine the school and family experiences of four of these students in an attempt (1) to provide data that contribute to the refutation of the stereotypical images and myths that are so pervasively used to …
The Rhetoric Of Redemption: A Development Of Kenneth Burke's Theory Of Guilt-Purification-Redemption And Its Application To Martin Luther King, Jr.'S "I Have A Dream" Speech., David A. Bobbitt
LSU Historical Dissertations and Theses
This dissertation presents an exposition and development of Kenneth Burke's theory of guilt-purification-redemption (also referred to as the "redemption drama"), and then an application of that theory through a critical analysis of Martin Luther King, Jr.'s "I Have a Dream" speech. King's speech is treated as the "representative anecdote" of the moderate wing of the first phase of the civil rights movement. The speech became an authorizing text on race relations and provided the movement with an articulation of its logic and narrative form. Usually Burke's theory is seen as positing two primary modes of purification of guilt: victimage and …
Centralization And Decentralization: The Relationship Of Bureaucracy, Autonomy And The Principalship In Elementary Schools., Cheryl Berot Boutte
Centralization And Decentralization: The Relationship Of Bureaucracy, Autonomy And The Principalship In Elementary Schools., Cheryl Berot Boutte
LSU Historical Dissertations and Theses
Throughout the last decade, parents and communities have continued to press for more control over their schools in an attempt to improve performance. Members of the educational community have begun calling for school restructuring to return decision making power to the school site professionals. These calls for the decentralization of our highly centralized school systems have prompted educators, researchers and political scientists to examine the organizational settings in which schools operate. This study investigated the influence of organizational structure, namely centralized bureaucracy and decentralized autonomy on school leadership and the relationship of that leadership to the school's culture. The study …
The Theatre Of Religion: Jimmy Swaggart Within American Myth Discourse., Terry Grant Byars
The Theatre Of Religion: Jimmy Swaggart Within American Myth Discourse., Terry Grant Byars
LSU Historical Dissertations and Theses
This study explores the myth of the self-made man in American popular culture and how Jimmy Swaggart, the renowned televangelist, manipulates this myth in representing himself as an American hero. Central to such inquiry is Swaggart's use of theatrical device in promoting his heroism. Three fundamental questions provide the focus for investigation: (1) How in general does the creation of myth serve the needs of culture? (2) How specifically does the myth of self-made-ness benefit American culture? and (3) How is Swaggart able to participate in this powerful myth (especially using theatrical modes) in order to gain cultural sanction? In …
Jeremy Rifkin Challenges Recombinant Dna Research: A Rhetoric Of Heresy., Wiley Michael Futrell
Jeremy Rifkin Challenges Recombinant Dna Research: A Rhetoric Of Heresy., Wiley Michael Futrell
LSU Historical Dissertations and Theses
Western culture, in large part, is a product of scientific inquiry, technological development and the ability to harness some of nature's resources. Much of society looks to science for technology-related solutions to many of its ills. As it develops new technology, science necessarily seeks to understand and control the forces of nature. Although science assumes a prominent role in contemporary society, that prominence does not necessarily translate into cultural consensus on the progress achieved by technological developments. Another perspective is represented by those who contend that continued technological advancement is the source of existing problems, not the solution. As these …
The Rhetoric Of Synnationalism: A Model Of Foreign Policy Discourse., Ralph A. Hamlett
The Rhetoric Of Synnationalism: A Model Of Foreign Policy Discourse., Ralph A. Hamlett
LSU Historical Dissertations and Theses
The United States, as other nation-states, claims legitimacy as an agency for the expression of the aspirations of its people. This political structure appeared as part of a historical process that implied a transfer of authority from ruling elite(s) to the public. However, U.S. foreign policy discourse evidences an incomplete relocation of authority. In matters of sovereignty and national interests, the policy establishment considers itself more capable of decisions than ordinary people. The establishment tends to view citizens as masses disinterested in and incapable of understanding vital decisions of the state. The policy establishment assumes the public's role is best …

LSU Historical Dissertations and Theses
This research studied dialogue journal writing, as it occurred between a teacher and twenty-one students in a French III high school. Results on attitude questionnaire indicated that dialogue journals helped students overcome their fear of the written form and increase their self-confidence and willingness to write. By demystifying the writing process, writing in their dialogue journals helped these students develop positive attitudes. The results on writing proficiency pre and post-tests indicated that students performed as well or better than students after four years of a foreign language in a high school setting or four semesters of college instruction. The dialogue …
The Use Of Hydrologically Altered Wetlands To Treat Wastewater In Coastal Louisiana., Andree Marie Breaux
The Use Of Hydrologically Altered Wetlands To Treat Wastewater In Coastal Louisiana., Andree Marie Breaux
LSU Historical Dissertations and Theses
Two major environmental problems currently affecting Louisiana are a high rate of coastal wetland loss and high levels of surface water pollution. The application of secondarily treated wastewater to wetlands is proposed as a means of dealing with these problems. The benefits of wetland wastewater treatment include improved surface water quality, increased accretion rates to balance subsidence, improved plant productivity, and decreased capital outlays for conventional engineering treatment systems. Wetland treatment systems can be designed and operated to restore deteriorating wetlands to previous levels of productivity. Hydrologically altered wetlands in the Louisiana coastal zone have been selected as appropriate for …

A Novel Process For The Production Of Clinical Dextran., Doman Kim
A Novel Process For The Production Of Clinical Dextran., Doman Kim
LSU Historical Dissertations and Theses
A new process for the production of clinical (or controlled size) dextran was developed. This process is simpler, cheaper and more economical than traditional methods. It involves the use of a mixed culture fermentation with a dextranase producing strain (Lipomyces starkeyi ATCC 74054) and a dextransucrase producing strain (Leuconostoc mesenteroides ATCC 10830). The new process produced 84% (w/w) of theoretical yield clinical dextran with an average polydispersity between 1.2 and 1.5. The mechanism of clinical dextran formation is the competitive production of acceptors from newly formed dextran molecules by dextranase. The acceptors compete for the existing glucosyl portion of sucrose, …
Theatrical Intervention In The Aids Crisis: Performance, Politics, And Social Change., Cindy J. Kistenberg
Theatrical Intervention In The Aids Crisis: Performance, Politics, And Social Change., Cindy J. Kistenberg
LSU Historical Dissertations and Theses
This purpose of this study is to assess the efficacy of performance as a means of social change by focusing on performances that have arisen out of the AIDS crisis. Working from a cultural studies perspective, I attempt to delineate both the possibilities and limitations for this perspective on social change. By comparing the various forms these performances have taken, I offer an explanation as to how these forms inhibit or enhance the ability of a performance to challenge the dominant discourse on AIDS, and create and mobilize communities that can act in the fight against AIDS. I begin by …
Cosmology And Curriculum: A Vision For An Ecozoic Age., Angela T. Lydon
Cosmology And Curriculum: A Vision For An Ecozoic Age., Angela T. Lydon
LSU Historical Dissertations and Theses
The text of this dissertation explores interconnections between cosmology and curriculum. I believe the demands of an Ecozoic Age will initiate a reconceptualizing of curriculum. Further, I believe the particular cosmological perspective I advance can help us with this reconceptualization. Chapter 1 utilizes the multi-faceted insights of scientific, historical, and speculative thought. The texts used in this chapter incorporate an engagement with past cultures (Ong, Eliade), with contemporary theoretical perspectives (Munitz, Haught, and Stafford), and with a scholarship that envisions alternative futures (Bohm). Chapter 2 uncovers how modernity's relationship to the earth is rooted in the scientific, political, and social …
A Computational Framework For Efficient Error Correcting Codes Using An Artificial Neural Network Paradigm., Maung Maung Htay
A Computational Framework For Efficient Error Correcting Codes Using An Artificial Neural Network Paradigm., Maung Maung Htay
LSU Historical Dissertations and Theses
The quest for an efficient computational approach to neural connectivity problems has undergone a significant evolution in the last few years. The current best systems are far from equaling human performance, especially when a program of instructions is executed sequentially as in a von Neuman computer. On the other hand, neural net models are potential candidates for parallel processing since they explore many competing hypotheses simultaneously using massively parallel nets composed of many computational elements connected by links with variable weights. Thus, the application of modeling of a neural network must be complemented by deep insight into how to embed …

Stress Begins In Kindergarten: A Look At Behavior During Standardized Testing, Pamela O. Fleege, Rosalind Charlesworth, Diane C. Burts, Craig H. Hart
Faculty Publications
Kindergarten children’s behavior before, during, and after standardized achievement testing was explored through a qualitative study in two classrooms (n = 36). Simultaneously quantitative data were collected in one of the classrooms (n = 21) before and during the testing. Data were collected through observations in the classrooms, interviews with children and teachers, and audio and video taping of the children. For the quantitative component of the study, frequencies of stress behaviors were observed using a scan sampling method. Qualitative findings indicated an increase in behaviors reported to be stress related during the testing and a decrease in those behaviors …
Quality Enhancement Through Goal-Setting: Examining The Effects Of Goal Attributes And Feedback On Performance., Paula Lynne Phillips
Quality Enhancement Through Goal-Setting: Examining The Effects Of Goal Attributes And Feedback On Performance., Paula Lynne Phillips
LSU Historical Dissertations and Theses
A laboratory experiment, using 165 students, was conducted to assess the effects of goal type (quantity vs quality), goal difficulty (difficult vs easy), goal specificity (specific vs nonspecific), and feedback type (goal-discrepant vs strategic) on performance. Subjects were asked to perform a heuristic task, appropriate for the assessment of both quantity and quality performance. Results indicated: (a) the provision of quality feedback will increase effort and will improve quality performance; (b) individuals value quality feedback more than they value quantity feedback; (c) individuals are more accurate in their prediction of quantity performance than they are in their prediction of quality …
One-Dimensional Nash Groups, James J. Madden, Charles M. Stanton
One-Dimensional Nash Groups, James J. Madden, Charles M. Stanton
Faculty Publications
A Lie group equipped with a compatible real algebraic structure is called a locally Nash group. We prove some general facts about locally Nash groups, then we classify the one-dimensional locally Nash groups, using a theorem of Weierstrass that characterizes the analytic functions satisfying an algebraic addition theorem. Besides the standard Nash structure on the additive group of real numbers, there are locally Nash structures on the additive reals induced by the exponential function, the sine function, and by any elliptic function that is real on ℝ. There are no other simply connected one-dimensional locally Nash groups. Any two quotients …
Extensions Of Tutte's Wheels-And-Whirls Theorem, Collette R. Coullard, James G. Oxley
Extensions Of Tutte's Wheels-And-Whirls Theorem, Collette R. Coullard, James G. Oxley
Faculty Publications
Tutte's wheels-and-whirls theorem states that if M is a 3-connected matroid and, for every element e, both the deletion and the contraction of e destroy 3-connectivity, then M is a wheel or a whirl. We prove some extensions of this theorem, one of which states that if M is 3-connected and has both a wheel and a whirl minor, then either M has only seven elements or there is some element the deletion or contraction of which maintains 3-connectivity and leaves a matroid with both a wheel and a whirl minor. © 1992.
