Pattern-Based Model Transformation: A Metamodel-Based Approach To Model Evolution, Sheena Judson Miller

LSU Doctoral Dissertations

Software systems continue to grow in complexity at a rapid pace, creating systems that are complex to build and evolve. The problems that accompany changes in requirements, system upgrades, and error correction produce a desire for software evolution methods that increase the efficiency and effectiveness of adapting complex software to changes. As software systems evolve, design models must be modified to accommodate the required changes. Techniques that control the changes to models in a systematic manner are a key to model evolution. A process that improves the ability to effectively modify a design, thereby enhancing design qualities, supports the need …

Seasonal Occurrence Of Phyllophaga Species And Biological Studies Of Phyllophage Ephilida (Say) On Sweet Potato, Ipomoea Batatas (L) Lam, In Louisiana, Aboubacar Diagne

LSU Doctoral Dissertations

The biology of Phyllophaga ephilida (Say) was studied in Louisiana with both laboratory and field experiments from 1998 through 2003. The seasonal occurrence of common adult Phyllophaga species in sweet potato growing areas was surveyed with blacklight traps. P. ephilida and P. crinita (Burmeister) were the most common species at all locations. The attractiveness of seven methyl esters of L-isoleucine and L-valine blends to P. ephilida males was evaluated in sweet potato fields in 1999 and 2000. The 100% methyl ester of L-isoleucine was significantly more attractive than all other blend ratios that were tested. The life cycle of P. …

Mems Accelerometer: Proof Of Concept For Geotechnical Engineering Testing, Keith Nicholas Hoffman

LSU Master's Theses

Geotechnical engineering materials are inherently variable, which leads to many simplifications when trying to model their behavior. The materials must always be characterized prior to any design work so that the engineer knows which direction he must progress to have a reliable design. Although subsurface characterization techniques and geotechnical design steadily improve, they are by no means infallible. The combination of geotechnical subsurface characterization along with geophysical techniques for improved design and construction monitoring has begun to surface as a viable alternative to the standard techniques in geotechnical engineering. This is important because there is a lack of Quality Control/Quality …

What Is The Sound Of A Corporation Speaking? How The Cognitive Theory Of Metaphor Can Help Lawyers Shape The Law, Linda L. Berger

Scholarly Works

This article argues that better understanding of metaphor's cognitive role can help lawyers shape judicial decision-making. As a way of exploring metaphor's contribution to shaping the law, the article focuses on how a particular lawsuit was influenced by metaphor, in particular, by the primary metaphor that a corporation is a person within the more complex metaphorical system suggested by the marketplace of ideas model for First Amendment protection. After describing the cognitive theory of metaphor and examining the metaphors underlying First Amendment protection for corporate speech, the article analyzes the use of metaphor in the briefs filed in the U.S. …

Improved Methods For The Isolation And Characterization Of Flavobacterium Columnare, Bradley Donovan Farmer

LSU Master's Theses

Columnaris disease, caused by the bacterium Flavobacterium columnare, is an economically significant problem in many warmwater fish species. Difficulties encountered in the isolation and culture of F. columnare have been an impediment to research on the organism and the disease it causes. The goal of this study was to improve the methods for isolation, culture, identification and maintenance of F. columnare. Following the evaluation of different culture media selective cytophaga agar was determined to be the optimum isolation medium, Flavobacterum columnare growth medium proved to be the optimum culture medium, and tryptone yeast extract agar with increased moisture was best …

Stormwater Diversion As A Potential Coastal Wetland Restoration Method, Jennifer Howard Woods

LSU Master's Theses

The Barataria-Terrebonne estuary has been eroding at a rate of up to 103.6 km2 yr-1 for several decades. If the current rate of loss is not reduced, an additional 2,550 km2 of coastal wetlands will be lost by the year 2050. Currently, stormwater in Terrebonne Parish is pumped into canals, ultimately discharging into the Gulf of Mexico. An opportunity exists to use this stormwater for wetland restoration; however, the ecological impacts of stormwater diversions on wetlands are unknown. The objectives of this project were to 1) to investigate the seed banks of a degraded marsh to determine if a viable …

From Oklahomans To "Okies": Identity Formation In Rural California, Toni Ann Alexander

LSU Doctoral Dissertations

Throughout the twentieth century difficult economic circumstances have resulted in reduced employment opportunities. In-migrants have long borne the brunt of these limitations, facing open hostilities from residents who felt that these "outsiders" were undeserving of employment and social services. Within the context of the 1930s Depression in the Central Valley of California, such negative public sentiment was often directed at "Okies," the 315,000 former residents of the "Western South" who crossed the California state line in search of employment in the agricultural fields of the Golden State. In this dissertation, I examine the changing conceptualizations of Okie identity throughout the …

The participants of this study were 114 students who were identified and served under Delinquency Prevention Program (DPP) and 83 students who were identified and served under Court Ordered Probation (COP). The Test of Written Language -3 (TOWL-3) (Hammill & Larsen, 1996) was administered to the participants in order to obtain written language measures. In addition, this study investigated whether any relationships exists between written language skills, academic measures and selected demographic characteristics of …

Difference In Sleep Disturbances Among Severely And Profoundly Retarded Adults With High Risk Behaviors, Carrie Jo Malone

LSU Master's Theses

Individuals with intellectual disabilities have been linked to higher incidences of a variety of mental illnesses when compared to the general population (Rutter, Tizard, Yule, Graham, & Whitmore, 1976; and Borthwick-Duffy, 1994). Because of the symptoms associated with mental retardation; such as limited social skills, delayed or minimal communication skills, and maladaptive behaviors, mental illness can be difficult to assess when combined with an intellectual disability (Sovner, 1986). Currently there is no available mechanism for diagnosing sleep disorders in adults with severe and profound mental retardation. The purpose of the first study is to provide validation of the Diagnostic Assessment …

North Korean Invasion And Chinese Intervention In Korea: Failures Of Intelligence, Robert A.Ii Culp

LSU Master's Theses

The America intelligence community in 1950, unprepared to perform its missions, failed to provide adequate indications and warning to U.S. national leaders and to the Commander, Far East Command (FEC), about the North Korean invasion of South Korea and Red Chinese intervention in the Korean War. Post-World War II policies that reduced the size of the military, cut systems and training, and reorganized intelligence services are responsible for that failure. Training deficiencies meant that intelligence soldiers deployed to Korea without required skills. The military trained analysts to assess enemy capabilities rather than intentions, contributing to poor predictive analysis. Shortages of …

Analysis Of Factors That Affect Responding In A Two-Response Chain In Children With Developmental Disabilities, Stephanie Ann Contrucci Kuhn

LSU Doctoral Dissertations

Behaviors that are appropriate, inappropriate, or a combination of both can be linked together in a behavior chain. When the contingencies for one response change (e.g., reinforcement is withheld for the last response in the chain; the last response is reinforced even if it occurs without the other responses in the chain) or the environmental conditions change (e.g., access to the reinforcer is available independent of responding), the other responses in the chain may be affected. Little is known about these types of effects on behavior chains. Several operant processes may disrupt behavior chains. The purpose of this study was …

Using Arbitration To Eliminate Consumer Class Actions: Efficient Business Practice Or Unconscionable Abuse?, Jean R. Sternlight, Elizabeth J. Jensen

Scholarly Works

Companies are increasingly drafting arbitration clauses worded to prevent consumers from bringing class actions against them in either litigation or arbitration. If one looks at the form contracts she receives regarding her credit card, cellular phone, land phone, insurance policies, mortgage, and so forth, most likely, the majority of those contracts include arbitration clauses, and many of those include prohibitions on class actions. Companies are seeking to use these clauses to shield themselves from class action liability, either in court or in arbitration.

This article argues that while the unconscionability doctrine offers some protections, case-by-case adjudication is a costly means …

A Spatial Analysis Of The Smallpox Epidemic In Sheffield, United Kingdom, 1887-1888, Ann-Marie Cain

LSU Master's Theses

One of today's most fecund fields of research in medical geography involves using historical datasets from past epidemics and contemporary cadastre maps to plot the course of the contagion. The purpose is to study the spatial patterns of diseases that are rare or extinct today but still have large research value. The best example of this problem is smallpox. This project involves taking one of the most complete records of a smallpox epidemic, plotting the cases in a geographic information system (GIS), and exploring the spatial patterns using statistical software. As one of the most contagious and damaging diseases to …

The Effects Of Reinforcement Magnitude On Functional Analysis Outcomes, Valerie Marie Volkert

LSU Master's Theses

The functional analysis methodology developed by Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994) has been successfully used to identify the variables that maintain the problem behavior of individuals with developmental disabilities. However, in some cases, the results of functional analysis may be inconclusive. Altering parameters of reinforcement, such as the schedule, the quality, or magnitude of the reinforcer, may increase the likelihood of obtaining clear functional analysis results. Few studies have evaluated the effects of reinforcement magnitude on problem behavior even though basic findings indicate that this parameter may alter functional analysis outcomes. In fact, reinforcement magnitude has varied widely …

Minimum Dogma And Religious Toleration, Clinton Bryan Barron

LSU Master's Theses

This thesis examines issues that emerge from the investigation of the relationship between John Locke's arguments for religious toleration as found in his Letter Concerning Toleration and his construction of a minimum dogma for Christianity in his The Reasonableness of Christianity. The first chapter follows the development of minimum dogma from its origin in the experience Eric Voegelin terms the leap in being, through Xenophanes' concept of "seemliness," to the minimum dogmas of Plato. The second chapter examines the use of minimum dogma in theories of religious toleration by More and Spinoza. The final chapter examines the work of John …

William Faulkner And The Oral Text, Gregory Alan Borse

LSU Doctoral Dissertations

The disjunction between the oral and the literate in the works of William Faulkner reveals the different ways these distinct modes of organization combine to structure a text. The oral in Faulkner's fiction makes its presence known not only as offset speech but also as a mode of action and narrative whose logic is conjunctive rather than disjunctive. According to the literate mode, a form organizes novelistic matter. According to the oral mode, forces that function as signs rather than organizers of their form rule the action and narrative. When the disjunction between the oral and the literate is so …

Credibility And Authority On Internet Message-Boards, Ryan Goudelocke

LSU Master's Theses

This research aimed to provide some proof or refutation of the hypothesis that online communities develop specialized vocabularies, often technical jargon, and use elements of those vocabularies, here labeled “tokens,” to ascribe credibility and/or authority to other posters. The literature from a variety of communications fields relating to this topic was summarized as a progression from an early “limitations” model of computer-mediated communication (CMC) to a later “opportunities” model. The drawbacks of current research were outlined and some new paths were sketched, including the methodology employed here. Several discussions from different Web sites, each containing hundreds of posts, were tabulated …

That Memorable Campaign: American Experiences In The China Relief Expedition During The 1900 Boxer Rebellion, Eric T. Smith

LSU Master's Theses

At the time of the Boxer Rebellion in China in 1900, the American army was not experienced in dealing with challenges abroad. The Army spent the last quarter of the nineteenth century fighting the Indian Wars in the West and a generation of officers grew to maturity commanding small frontier posts where only a few had the opportunity to maneuver large formations during the Spanish-American War. The infantrymen who marched into Peking in August of 1900 were transitioning between the tactics of the past and the future. The Napoleonic formations used in the American Civil War, already made obsolete at …

Investigation Of Insect-Weed Interactions In The Rice Agroecosystem, Kelly V. Tindall

LSU Doctoral Dissertations

Interactions between graminaceous weed and insect pests of rice and between management practices for these pests were investigated. Studies were conducted to examine preference and performance of rice water weevil, Lissorhoptrus oryzophilus Kuschel, on several weeds commonly found in rice fields. Several weeds were more preferred than rice, and larvae were present on several dicotyledonous weeds, suggesting the host range of L. oryzophilus is broader than previously thought. Effects of the presence of barnyardgrass, (Echinochloa crus-galli Beauv.), on rice stink bugs, Oebalus pugnax F., and L. oryzophilus populations in rice fields were investigated. Presence of barnyardgrass and the synchrony …

Volatiles Associated With Formosan Subterranean Termites And Related Methods Development, Paul Mclaughlin

LSU Master's Theses

An investigation was conducted to identify volatiles associated with active Formosan termites. Using a combined technique of short path thermal desorption-gas chromatography/mass spectrometry (SPTD-GC/MS), qualitative comparisons were made between compounds detected in treatments containing active Formosan termites versus those detected in controls without Formosan termites. Except for dimethyl disulfide, none of the compounds were consistently detected in the treatments but not the controls for the four termite groups tested. However, in each of the three groups that dimethyl disulfide was detected, dead termites that were decomposing along with active termites were present. Therefore, none of the compounds could be classified …

Performing Masculinities: U.S. Representations Of The Male Body In Performance Art Monologues, Darren C. Goins

LSU Doctoral Dissertations

In this study, I describe and analyze the masculinities constructed in four performance art monologues staged in the US on Broadway. I examined Whoopi Goldberg’s 1984 performance Whoopi Goldberg Live, Lily Tomlin’s 1987 performance in Jane Wagner’s The Search for Signs of Intelligent Life in the Universe, Eric Bogosian’s 1990 performance Sex, Drugs, Rock & Roll, and John Leguizamo’s 1998 performance Freak: A Semi-Demi-Quasi-Pseudo Autobiography. My method of analysis is a critical interpretation incorporating the lenses of Robert Connell and Victor Seidler. It is grounded in a social-cultural perspective using Arthur W. Frank’s “sociology of the body.” By means of …

The Figuration Of Caliban In The Constellation Of Postcolonial Theory, Paulus Sarwoto

LSU Master's Theses

The surrogation of Caliban from Shakespeare’s The Tempest to Césaire’s A Tempest has always been related to colonialism. In Shakespeare’s time, Caliban, depicted as half animal, served to represent the Other in an emerging colonial discourse. As opposed to Shakespeare’s character, Césaire’s Caliban is blatantly black and racially oppressed. Césaire indicates that A Tempest is an adaptation of Shakespeare’s The Tempest for black theater. As an adaptation, the play reinterprets the figure of Caliban to express postcolonial attitudes of the time. This thesis addresses the questions of how the figure of Caliban in Shakespeare’s play fits into the discourse of …

Adult Attachment Styles, Children's Self-Competence, And Children's Cognitive Ability: An Ecological Study, Elizabeth Benchea Block

LSU Doctoral Dissertations

This study investigated children's perceived self-competence and its relationship to the social antecedent of adult attachment and the outcome of children's cognitive ability. Utilizing a predominantly African American sample, 154 mothers, 80 fathers and 205 children were included in this cross-sectional study of second and fourth grade children. Regression analyses indicated that the exploratory relationship between adult attachment as a predictor of children's self-competence was upheld with both second and fourth grade children of participating mothers and fathers. More specifically, maternal attachment was a significant predictor of second grade children's perceived physical competence, social acceptance, and maternal acceptance. Maternal attachment …

Attribution Processes In Mother-Adolescent Conflict, Ann Elisabeth Wingate

LSU Master's Theses

The present study aimed to determine whether negative mother and adolescent attributions about one another are associated with increased conflict levels in a heterogeneous sample, examine the possible differential predictive power of certain negative attribution types for different groups within the sample, determine whether level of negative attribution, SES, or daily stress level are significant predictors of conflict, and examine the potential mediating role of negative attributions in the relationship between SES and conflict level, as well as the relationship between and daily stress and conflict level. One hundred forty-five mother-adolescent dyads from various racial and SES backgrounds of a …

What Irritates Consumers?: An Empirical Examination Of The Antecedents And Consequences Of Consumer Irritation, Sweta Chaturvedi Thota

LSU Doctoral Dissertations

This dissertation develops a model of consumer irritation in the context of consumer decision-making. Thus, the purpose is to describe and empirically test a model of the antecedents and consequences of consumer irritation. The model incorporates antecedents, moderators and consequences of irritation. It is suggested that irritation in consumers has a direct as well as an indirect influence, through retention of irritation in consumers, on the outcome variables such as attitude towards the advertised brand, and intentions to engage in negative word of mouth (NWOM) behavior. The central aim of this dissertation is to extend our understanding of the irritation …

Quantification Of Marine Sediment Properties From Planar And Volumetric Pore Geometries, Allen Hagerman Reed

LSU Doctoral Dissertations

Pore geometry and topology are important determinants of sediment physical properties, such as porosity and permeability. They also influence processes that occur in the sediment, such as acoustic propagation, attenuation, and dispersion, single- and multi-phase fluid flow, and hydrodynamic dispersion. This study uses images to evaluate pore geometry and topology of ooid (subspherical particles) and siliclastic (angular quartz) sand that was collected from the marine environment south of Bimni Bahamas and Ft. Walton Beach, FL, respectively. Image analysis techniques and predictive tools enable insight into the relationships among sediment pore geometry, topology, and physical properties for these differently shaped sands. …

Nadzab (1943): The First Successful Airborne Operation, James Philip Lowe

LSU Master's Theses

The U.S. Army in 1940 was in the early stages of developing an airborne capability to exploit the vertical envelopment concept. That concept became reality in 1942 with the first airborne operation in North Africa. Although the first parachute drop contributed virtually nothing to the overall success of the mission, it was the beginning of an important capability. In 1943, the War Department authorized five airborne divisions despite a lack of experience and doctrine to direct the new organizational structure. The airborne initiative expanded much more quickly than did the doctrine, training, or employment principles. The first attempts of conducting …
