Experimental Investigation Of Drilling Fluid Formulations And Processing Methods For A Riser Dilution Approach To Dual Density Drilling, John Shelton
LSU Master's Theses
Oil and natural gas resources in the deepwater Gulf of Mexico are important for the U.S. economy, but development is limited by high costs. Dual density drilling concepts that result in wellbore pressure gradients similar to the natural subsurface gradients can simplify well designs and reduce costs. Riser dilution may be an economical means of achieving such a system. This system would use a low density fluid to dilute the weighted wellbore fluid and give an intermediate density fluid in the riser. Two key concerns addressed in this study are whether a drilling fluid can be formulated that will suspend …

Three Choral Compositions By Alice Parker: A Conductor's Analysis Of Songstream, Angels And Challengers, And Songs From "The Dragon Quilt", Jennifer Sue King
LSU Major Papers
Alice Parker (b. 1925) has earned a place of respect in choral music through more than half a century of work in arranging and composition, conducting, teaching and writing. Her works reflect diverse interests, from short, unison pieces for treble choir, to the complexity of unaccompanied madrigals, to major choral/orchestral works and operas. Conductors and singers all over the world have been influenced by her writings, seminars and SINGS, and she continues to extol the value of music, both in the concert hall and as a part of everyday life. Scholarly research of her choral compositions is limited, and further …
"I Cried Out And None But Jesus Heard!" Prophetic Pedagogy: The Spirituality And Religious Lives Of Three Nineteenth Century African-American Women, Elecia Brown Lathon
"I Cried Out And None But Jesus Heard!" Prophetic Pedagogy: The Spirituality And Religious Lives Of Three Nineteenth Century African-American Women, Elecia Brown Lathon
LSU Doctoral Dissertations
African American women represent a long line of prophetic women. Women who fought for space in the religious world of the nineteenth century, and who fought to have their voices heard in America. The lives and experiences of such women have been excluded, ignored, and dismissed from academic discourses. This study adds a new dimension (the spirituality of African-American women) to the field of curriculum theory and builds on the scholarship of literary scholars who have and are currently recovering the lost lives of African American women and their spirituality. Therefore, this research examined the spirituality and rhetorical strategies utilized …
La Grande Force Est Le D'Sir: Guillaume Apollinaire's Rewriting Of Merlin's Mother And The Dame Du Lac In L'Enchanteur Pourrissant, Allison Bateman Roark
La Grande Force Est Le D'Sir: Guillaume Apollinaire's Rewriting Of Merlin's Mother And The Dame Du Lac In L'Enchanteur Pourrissant, Allison Bateman Roark
LSU Doctoral Dissertations
This dissertation analyzes Guillaume Apollinaire's rewriting of Merlin's mother and the Dame du Lac in L'Enchanteur pourrissant as a commentary on writing. I consider Merlin's state in the tomb as an effect of his desire for the Dame du Lac and relate this to the poet's relationship to writing, which is the result of his desire for a unity of expression -- to express what can be designated in the text, but not directly communicated in its totality through language. There is always something missing from any writing, but the very absence of meaning influences poetic production by encouraging attempts …
Non-Medical Skills And Competencies Needed By Paraprofessional Caregivers, Martha L. Dix
Non-Medical Skills And Competencies Needed By Paraprofessional Caregivers, Martha L. Dix
LSU Doctoral Dissertations
This research effort was intended to identify the non-medical job skills projected to be needed by in-home paraprofessional caregivers of today and beyond as indicated by a Delphi panel of caregiving experts from public and private business areas as well as academia. Thirty Delphi participants were selected based on a qualifying questionnaire. Actual respondents, however, numbered 29 for Round 1, 24 for Round 2 and 23 for Round 3. Each round asked participants to respond to a survey as prompted by an open ended statement. Within the Round 1 process, participants indicated which non-medical skills from the prepared list they …
Constructing Resilent Marital Relationships: A Panel Study Of Marriages Under Pressure, Amy Manning
Constructing Resilent Marital Relationships: A Panel Study Of Marriages Under Pressure, Amy Manning
LSU Doctoral Dissertations
In the past, much of the literature on marital quality and stability has suggested that effective communication, positive affect, and spouses’ emotional support are important to marital quality (Gottman and Levenson, 2000; Gottman and Notarius, 2000 Popenoe, 2004; Sanchez and Ganger, 2000; Whitehead and Popenoe, 2001). Other works have also suggested that “commitment,” that is feelings regarding the permanency of marriage, encourages marital quality. However, to date, few studies have empirically investigated the relationship between commitment and marital quality (Surra and Gray, 2000). This dissertation investigates the relationships between commitment, marital disruption and instability, and marital quality, utilizing the context …
Exile As Severance, Alexandru Boldor
Exile As Severance, Alexandru Boldor
LSU Doctoral Dissertations
Exile is a phenomenon probably as ancient as humanity itself, and one of the oldest topics in universal literature. The great majority of its variants (political, economical, social,) are founded on the idea of "forced displacement." Consequently, most often exile is reflected in literary creations in discourses dominated by a sentiment of loss. However, in some cases exile is not seen as a tragic event, but rather as an opportunity for intellectual growth - as attested by a number of authors who have chosen voluntarily to exile themselves. The rationale behind this occurrence is a mental process I called "severance." …

Conceptualization And Cognitive Relativism On Result In Mandarin Chinese: The Case Study Of Mandarin Chinese Bǎ Construction Using A Cognitive And Centering Approach, Jin Huei Enya Dai
LSU Doctoral Dissertations
This work adopts Langacker's cognitive grammar approach and addresses the cognitive significance of result in Mandarin Chinese, as expressed in resultant construals in the Mandarin Chinese bă construction: X bă Y Z. I identify the semantic prime of result in Mandarin Chinese, and discuss its role in the resultative verbal compound construction, the V-de-EXT resultative construction, and the bèi construction, with particular focus on the bă construction. I provide evidence for the resultant nature of segment Z in the bă construction in (1) aspectual markers, (2) resultative suffixes, (3) resultative verbal compounds, (4) locative complements, (5) directional complements, (6) the …
Civic Orientation Predictors Of Black Students: An Exploratory Study, Joe Lee Lott Jr
Civic Orientation Predictors Of Black Students: An Exploratory Study, Joe Lee Lott Jr
LSU Doctoral Dissertations
Institutions are becoming more cognizant of preparing students for global leadership through measures such as service-learning and community service. Colby and her colleagues (2003) suggest that institutions should guide students to believe that they are members of a shared social structure. Black students are a group whose civic participation has sharply declined between the 1970s and 1990s (Putnam, 2000) when 50 years ago they were one of the most active civic groups (Davis, 1993). This exploratory study investigated the relationships between Black students’ citizenship perspectives and independent variables such as institution type, racial identity, gender, classification, major, age, and socioeconomic …
The Compositional Style Of Judith Lang Zaimont As Found In Nattens Monolog (Night Solilquy), Scena For Soprano Voice And Piano With Text By Dag Hammarskjöld, Joo Won Jun
LSU Doctoral Dissertations
American composer, Judith Lang Zaimont (b. 1945), has composed a considerable number of solo vocal works as well as multiple works encompassing a variety of genres. Zaimont's Nattens Monolog (Night Soliloquy), scena for soprano and piano, is one of several lengthy solo vocal works. Although written for solo voice, the music takes on the form of opera without operatic materials such as costume or staging. Commissioned by Arleen Auger, soprano, and Dalton Baldwin, pianist, Nattens Monolog was composed in 1984 and first performed by them at Lincoln Center in March of 1985. The primary focus of this paper will be …

A Correlational Study Examining The Relationship Between Invented Spelling And Beginning Reading, Jane Mcdaniel Grove
LSU Doctoral Dissertations
This research study was designed to investigate correlations between invented spelling patterns and beginning reading for low-performing and on-level boys and girls in kindergarten. Two research questions were examined: (1) Is there a statistically significant relationship between invented spelling as displayed in task and reading skills as measured by DIBELS? and (2) Does the performance displayed in task and reading skills as measured by DIBELS differ significantly for boys and girls in kindergarten? Student performance data was gathered using extant school Dynamic Indicators of Basic Early Literacy Skills (DIBELS) benchmarks at collected at midyear of kindergarten. It was hypothesized that …
Biologically Inspired Learning System, Patrick Mcdowell
Biologically Inspired Learning System, Patrick Mcdowell
LSU Doctoral Dissertations
Learning Systems used on robots require either a-priori knowledge in the form of models, rules of thumb or databases or require that robot to physically execute multitudes of trial solutions. The first requirement limits the robot’s ability to operate in unstructured changing environments, and the second limits the robot’s service life and resources. In this research a generalized approach to learning was developed through a series of algorithms that can be used for construction of behaviors that are able to cope with unstructured environments through adaptation of both internal parameters and system structure as a result of a goal based …
Samuel Beckett And Bilingualism: How The Return To English Influences The Later Writing Style And Gender Roles Of All That Fall And Happy Days, Julien F. Carriere
Samuel Beckett And Bilingualism: How The Return To English Influences The Later Writing Style And Gender Roles Of All That Fall And Happy Days, Julien F. Carriere
LSU Doctoral Dissertations
This dissertation addresses Samuel Beckett's bilingualism in an effort to understand how the author's use of language affected his writing style and depiction of gender. Beckett began writing in English, switched to French for the composition of new works for ten years, and then returned unexpectedly to English. His first English works are characterized by stylistic virtuosity, erudition, and misogyny. With Beckett's adoption of French his style became simple, spare, and cerebral. Plot structure based on a journey in early works was abandoned in favor of static situations and dialogue. Women were either ignored or viewed negatively. In 1956, Beckett …
Conspiracy Culture In America After World War Ii, Valerie Rose Holliday
Conspiracy Culture In America After World War Ii, Valerie Rose Holliday
LSU Doctoral Dissertations
Feminism has all too often been reified as a theoretical category. Specifically, Marxist critical categories fail to account for the integral importance of gender in any sociopolitical critique. This dissertation attempts to dereify gender and demonstrate a theoretical model that seamlessly integrates psychoanalysis, Marxism, and feminism. Conspiracy culture in America since World War II is an ideal aperture through which we may envision such a theoretical approach, and indeed see the critical need for such an approach. This dissertation looks at several post-war American conspiracy narratives, including Oliver Stone’s JFK and Nixon, Don DeLillo’s Libra, Sidney Lumet’s Fail Safe, John …
Creating Meaning In Organizational Change: A Case In Higher Education, Kathleen Barnett
Creating Meaning In Organizational Change: A Case In Higher Education, Kathleen Barnett
LSU Doctoral Dissertations
As change is an inevitable part of organizational life, this study explores one aspect of communication in organizational change: the creation and use of meaning during the change process. The implementation of a new, higher education admissions criteria framework of a state master plan is the specific change under study. University administrators, contracted consultants, and board staff members participated in the study. Framed by symbolic interactionism and a stakeholder perspective, I pose four research questions: RQ1: What meanings were created during the particular process of change under study? RQ2: How were meanings intentionally and unintentionally created among stakeholders during this …
The Relationship Between Participation In Community Service-Learning Projects And Personal And Leadership Life Skills Development In Louisiana High School 4-H Leadership Activities, Connie S. Phelps
LSU Doctoral Dissertations
Evidence does not exist that documents the effectiveness of Louisiana 4-H community service-learning projects. The purpose of this study is to compare self-reported perceptions of personal and leadership life skills development of Louisiana high school 4-H leadership activity participants by whether they participate in the 4-H Junior Leader Club (JLC) and/or the CHARACTER COUNTS! (CC) peer teaching program. The target population for this study was all high school students who participated in either the CC peer teaching program or the 4-H JLC. Therefore, this study was limited to those parishes that have both a CC peer teaching program and a …
Genetics And Functions Of The Sars Coronavirus Spike Protein, Chad Michael Petit
Genetics And Functions Of The Sars Coronavirus Spike Protein, Chad Michael Petit
LSU Doctoral Dissertations
The SARS-Coronavirus (SARS-CoV) is the etiological agent of the severe acute respiratory syndrome (SARS). The SARS-CoV spike (S) glycoprotein mediates membrane fusion events during virus entry and virus-induced cell-to-cell fusion. Investigations, described herein, have focused on the genetic manipulation of the SARS-CoV S glycoprotein in order to delineate functional domains within the protein. This was accomplished by incorporating single point mutations, cluster-to-lysine and cluster-to-alanine mutations, as well as carboxyl terminal truncations into the protein and investigating these mutants in transient expression experiments. Mutagenesis of either the coiled-coil domain of the S glycoprotein amino terminal heptad repeat, the predicted fusion peptide, …
Jean-Paul Sartre's Les Mots And The Nouvelles Autobiographies Of Alain Robbe-Grillet, Nathalie Sarraute, And Marguerite Duras: A Comparison, Julie Driessen
Jean-Paul Sartre's Les Mots And The Nouvelles Autobiographies Of Alain Robbe-Grillet, Nathalie Sarraute, And Marguerite Duras: A Comparison, Julie Driessen
LSU Doctoral Dissertations
Jean-Paul Sartre's autobiography Les Mots (1964) is shown to be a departure from the Sartrean oeuvre because it represents an abandonment of littérature engagée. In Les Mots Sartre not only abandons littérature engagée, but also embraces a view of literature which he formerly opposed--l'art pour l'art. Sartre defines his views of literature--littérature engagée--in Qu'est-ce que la littérature? (1948) Robbe-Grillet defines l'art pour l'art in Pour un nouveau roman (1963). In Les Mots Sartre embraces Robbe-Grillet's l'art pour l'art and abandons his own littérature engagée. Since these two views of literature are theoretically opposed, it is interesting to find that Sartre …
Recovering Ancient Ritual And The Theatre Of The Apache: A Journey Through The False Consciousness Of Western Theatre History, Marla Kathleen Dean
Recovering Ancient Ritual And The Theatre Of The Apache: A Journey Through The False Consciousness Of Western Theatre History, Marla Kathleen Dean
LSU Doctoral Dissertations
This dissertation examines past cultural influences that have shaped theatre historians' perception of ancient Greek and contemporary Native American performance. It suggests that through a recognition of these influences, which have long tempered the Western narrative of theatre, ancient and Indigenous performance can be reviewed as similar forms of a lived exchange. The study tracks the formation of certain beliefs and assumptions within performance history through Roman, early Christian and Renaissance cultural identities. It notes the misrepresentation of oral and popular theatre within theatrical scholarship through its reliance upon the written remains of the ruling classes and confronts the notion …
Boston's Settlement Housing: Social Reform In An Industrial City, Meg Streiff
Boston's Settlement Housing: Social Reform In An Industrial City, Meg Streiff
LSU Doctoral Dissertations
Between the Civil War and World War I, American cities underwent dramatic changes: they changed in shape, they changed in size, they changed in terms of who was there, and how those individuals were distributed through the city. The driving force behind these urban morphological changes was industrialization – and the emergence of industrial slums on the edges of expanding business districts. These industrial slums were widely believed to breed disease, crime, intemperance, and immorality – external costs that were being born by the entire society. Yet American society and American philanthropic institutions were not prepared to deal with the …
Fabrication Of Core-Shell Nanoparticles, Zhanhu Guo
Fabrication Of Core-Shell Nanoparticles, Zhanhu Guo
LSU Doctoral Dissertations
Metallic Cu and Au shells were fabricated around cobalt nanoparticles. A new technique to coat nanoparticles with carbon coatings and poly(methyl methacrylate) (PMMA) was developed. The copper shell formation is a self-limiting process. A thin copper shell (0.82 nm) around the cobalt nanoparticle (1.56 nm) enhanced the magnetic property by increasing the blocking temperature from 124 K to 235 K for nanoparticles with a copper shell. The formed gold shell (0.67 nm) enhanced the cobalt nanoparticle magnetic property by increasing the blocking temperature above room temperature. The magnetic moment in the Co-Cu and Co-Au core-shell nanoparticle is much higher than …
The Role Of Teachers' Self-Efficacy In Increasing Children's Physical Activity, James Frederick Roth
The Role Of Teachers' Self-Efficacy In Increasing Children's Physical Activity, James Frederick Roth
LSU Doctoral Dissertations
It is well documented that elementary school children do not participate in recommended amounts of physical activity, and that elementary physical education programs generally are unable to insure that children engage in appropriate amounts of activity. One solution to this dilemma is to increase children’s activity levels through collaborative efforts such as whole school programs involving the classroom teachers. If this approach is to be successful, it is important to investigate ways that elementary classroom teachers can be actively involved in school level programs that will ultimately increase children’s physical activity levels. Elementary classroom teachers are often responsible for at …

The Efficacy Of Noncontingent Escape For Decreasing Disruptive Behavior During Dental Treatment, Patrick Michael O'Callaghan
The Efficacy Of Noncontingent Escape For Decreasing Disruptive Behavior During Dental Treatment, Patrick Michael O'Callaghan
LSU Doctoral Dissertations
Researchers have developed and demonstrated the effectiveness of a number of interventions to manage disruptive behavior in the dental setting. However, these treatments vary in terms of their effectiveness, invasiveness, effort to implement, and acceptability to families. This study evaluated the effects of noncontingent escape for reducing disruptive behavior in a pediatric dental setting. Within a multiple baseline design across subjects, five children were provided response-independent breaks via an automated cuing device. Results demonstrated reductions in escape-related behaviors (e.g., crying, body movements) for all children. Additionally, the intervention was implemented with high integrity and was favorably rated by the dental …
Low Dielectric Constant Fluorocarbon Films Containing Silicon By Plasma Enhanced Chemical Vapor Deposition, Yoonyoung Jin
Low Dielectric Constant Fluorocarbon Films Containing Silicon By Plasma Enhanced Chemical Vapor Deposition, Yoonyoung Jin
LSU Doctoral Dissertations
Use of low relative dielectric constant (low-k) material as an interlayer dielectric is among important approaches to reduce the RC time delay in high performance ultra-large-scale integrated circuits. Copper metallization is another approach besides the use of low-k material, in reducing the RC delay time, because of its well-known characteristics of low resistivity and high electromigration resistance. Fluorocarbon films containing silicon (SiCF) have been developed in this work for low-k interlayer dielectric applications below 50 nm linewidth technology. The films were prepared by plasma enhanced chemical vapor deposition (PECVD) using gas precursors of tetrafluoromethane as the source of active species …
The Effects Of Discrimination Training On Choice-Making Accuracy During Symbolic Perference Assessment Formats, Christina Marie Vorndran
The Effects Of Discrimination Training On Choice-Making Accuracy During Symbolic Perference Assessment Formats, Christina Marie Vorndran
LSU Doctoral Dissertations
The right of individuals with developmental disabilities to live fulfilling and normalized lives has been a focus of federal legislation and applied research over the past 30 years. Research has primarily focused on the identification and incorporation of preferred items and activities into the home and community environments of these individuals. Because of cognitive and communication limitations, some individuals with developmental disabilities require training to make choices that accurately reflect their preferences. Verbal choice methods are commonly used in everyday clinical practice; however, the accuracy of these methods for identifying actual preferences depends on the individual’s ability to make auditory …

Risk Assessment Of The Transfer Of Imazethapyr Herbicide Resistance From Clearfield Rice To Red Rice, Weiqiang Zhang
LSU Doctoral Dissertations
Potential outcrossing between Clearfield rice and red rice will have a direct impact on the management and long-term usefulness of imazethapyr technology for rice weed control. The principal objective of this research was to determine the rate and agronomic consequences for outcrossing between Clearfield rice and red rice in south Louisiana. Collection and analysis of red rice samples across two years and 24 commercial locations indicated that red rice infestation after imazethapyr application differed substantially at different Clearfield locations. Straw hull and awnless red rice was the principal biotype observed for both years. Red rice populations possessed extensive variation for …
Using Partial Least Squares Approach To Predict Factors That Contribute To The Impact Of E-Folios On Pre-Service Teachers' Learning, Tasha Hoover Christmas
Using Partial Least Squares Approach To Predict Factors That Contribute To The Impact Of E-Folios On Pre-Service Teachers' Learning, Tasha Hoover Christmas
LSU Doctoral Dissertations
Teacher-education programs have the responsibility to prepare their future teachers by instilling in them the desire, confidence, and ability to be reflective practitioners, lifelong learners who continues to grow and develop professionally after graduation (Klenowski, 2000). In an effort to fulfill this responsibility, Teacher-education programs are beginning to make reforms to adhere to national standards, which prompt them to create alternative means for assessing pre-service teacher's performance and the success of the teacher-education program. One such alternative is the electronic portfolio. This study investigated the use of Louisiana colleges and universities' electronic portfolio system known as PASS-PORT. The purpose of …
The Language And Politics Of Place: Autobiographical Curriculum In The American South, Michael Brian Casemore
The Language And Politics Of Place: Autobiographical Curriculum In The American South, Michael Brian Casemore
LSU Doctoral Dissertations
Place is central to the study of the American South. The question of the meaning and power of place underpinned the earliest efforts to define and understand the region, and place remains a crucial concept in an ongoing process of regional identification and inquiry. This study explores southern place autobiographically, historically, and theoretically in order to illuminate the subjective and social dimensions of place and to promote progressive conversation in the region. My inquiry is interdisciplinary. It draws on psychoanalysis, Southern studies, and the philosophy of place-as well as on theories of curriculum, literature, and art. If places can inspire …
Active Security Mechanisms For Wireless Sensor Networks And Energy Optimization For Passive Security Routing, Lydia Ray
LSU Doctoral Dissertations
Wireless sensor networks consisting of numerous tiny low power autonomous sensor nodes provide us with the remarkable ability to remotely view and interact with the previously unobservable physical world. However, incorporating computation intensive security measures in sensor networks with limited resources is a challenging research issue. The objective of our thesis is to explore different security aspects of sensor networks and provide novel solutions for significant problems. We classify security mechanisms into two categories - active category and passive category. The problem of providing a secure communication infrastructure among randomly deployed sensor nodes requires active security measurements. Key pre-distribution is …
