Properties Of Borate-Treated Strandboard Bonded With Pmdi Resin, Yiqiang Zhou Jan 2004

Properties Of Borate-Treated Strandboard Bonded With Pmdi Resin, Yiqiang Zhou

LSU Master's Theses

Random strandboards from mixed southern wood species were manufactured using calcium borate (CB) and zinc borate (ZB) as chemical additives and polymeric methylene diphenylmethane disocyanate (pMDI) as resin. There were four target levels of borate loading and two levels of resin content. Panel properties, including modulus of elasticity (MOE), modulus of rupture (MOR), internal bond (IB) strength, linear expansion (LE), thickness swelling (TS), leachability, and swelling and strength retention properties under cyclic relative humidity, were measured. The influence of borate content, borate type, and resin content on various properties was analyzed. It was found that the addition of borate negatively …

Difference In Sleep Disturbances Among Severely And Profoundly Retarded Adults With High Risk Behaviors, Carrie Jo Malone Jan 2004

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 …

Ethics And Literature: Love And Perception In Henry James, Sarah Hamilton Jan 2004

Ethics And Literature: Love And Perception In Henry James, Sarah Hamilton

LSU Master's Theses

In this paper I argue for the value of literature in ethical instruction. Following Martha Nussbaum, I argue that literature often promotes the kind of context-specific judgment, respect for the cognitive value of the emotions and empathy for others that are foundational to the kind of ethical judgment Nussbaum and I support. Like Nussbaum, I find that Henry James's novels evince these same ethical values and that his novels, especially the novels of the late phase, are therefore useful for ethical instruction. Unlike Nussbaum, however, I do not believe that James portrays erotic love as an emotion that is incompatible …

Analysis Of Factors That Affect Responding In A Two-Response Chain In Children With Developmental Disabilities, Stephanie Ann Contrucci Kuhn Jan 2004

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 …

A Spatial Analysis Of The Smallpox Epidemic In Sheffield, United Kingdom, 1887-1888, Ann-Marie Cain Jan 2004

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 Jan 2004

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 …

Rates Of Molecular Evolution And Their Application To Neotropical Avian Biogeography, Christopher C. Witt Jan 2004

Rates Of Molecular Evolution And Their Application To Neotropical Avian Biogeography, Christopher C. Witt

LSU Doctoral Dissertations

The tempo of evolution and the causes of rate variation among lineages are central foci of evolutionary biology. I evaluated two hypothesized sources of variation in molecular evolutionary rate, and I applied a variable molecular clock to estimate the timescale of diversification in three families of Neotropical birds. First, I examined the phylogenetic evidence for molecular punctuated equilibrium, the hypothesis that speciation drives accelerated molecular evolution. Recent findings that rates of DNA evolution and speciation are linked implicate molecular punctuated equilibrium as an important cause of rate variation among lineages. I used phylogenetic simulations to test this reported link, and …

William Faulkner And The Oral Text, Gregory Alan Borse Jan 2004

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 …

Consumer Sensory Characteristics Of Butter Cake Made From Wheat And Rice Flours, Ashley Elizabeth Bond Jan 2004

Consumer Sensory Characteristics Of Butter Cake Made From Wheat And Rice Flours, Ashley Elizabeth Bond

LSU Master's Theses

Rice is an important commodity in Louisiana and throughout the world. During the milling process, about 15% of rice kernels become broken. Louisiana produced approximately 2,011,000 hundred weights of broken rice kernels in 2002. Converting broken rice into rice-based products adds dollars back to broken rice. The market potential for rice in processed foods is huge. In the refrigerated and frozen baked foods category, it is approximately $14.3 billion; while in the baked snack foods and wholesale bakery foods category, it is approximately $31.4 billion. Approximately 1-2% of the United States population suffers from Celiac Spruce Disease, which is a …

Volatiles Associated With Formosan Subterranean Termites And Related Methods Development, Paul Mclaughlin Jan 2004

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 …

What Irritates Consumers?: An Empirical Examination Of The Antecedents And Consequences Of Consumer Irritation, Sweta Chaturvedi Thota Jan 2004

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 Jan 2004

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 Jan 2004

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 …

An Integrative Model Of Clients' Decision To Adopt An Application Service Provider, Yurong Yao Jan 2004

An Integrative Model Of Clients' Decision To Adopt An Application Service Provider, Yurong Yao

LSU Doctoral Dissertations

Application Services Providers (ASPs) exploit the economics of delivering commercial off-the-shelf software over the Internet to many dispersed users, but the decision-making process to adopt the ASP business model can be complex requiring a comprehensive consideration of various factors. As a new form of outsourcing, the ASP business model differs from traditional outsourcing models with respect to the attributes associated with vendors, clients, and applications. These differences are expected to demand decision models that are distinct from those in the traditional IS outsourcing. In this study, an integrative model for ASP adoption that incorporates economic determinants, strategic determinants, and social …

True Image, Janet K. Link Jan 2004

True Image, Janet K. Link

LSU Master's Theses

A still-life is often the painted record of a complex arrangement of objects. My aim in making the visual portion of TRUE IMAGE is to turn this sort of still-life inside out. Rather than arranging a collection of objects and making a painted or drawn image of the set up, I made simple images of things and arranged them with actual objects into three larger tableaux. The subjects of the paintings and drawings are these: checkerboards, objects, portraits, and shadows. The subjects of the tableaux are work (LABOR), home (DOMUS), and church (ECCLESIA). Viewed as a whole the exhibition asks …

Estimation Of Living Body Weight Based On Measurements Of Anterior Superior Iliac Spine Breadth And Stature, Jaime A. Suskewicz Jan 2004

Estimation Of Living Body Weight Based On Measurements Of Anterior Superior Iliac Spine Breadth And Stature, Jaime A. Suskewicz

LSU Master's Theses

Standard identification criteria for creating a decedent’s biological profile typically include ancestry, sex, age, and stature, but not body weight. Body weight information may not only assist in creating a more complete biological profile but may also provide insight into other forensic considerations, such as taphonomy and body transport and disposal. The current study seeks to establish multiple regression equations for the prediction of living body weight in skeletal remains. Specifically, the measurements of anterior superior iliac spine (ASIS) breadth and stature are assessed with regard to living weight. Research was carried out on both a skeletal sample and a …

Escalation Bias In Group Decision-Making, Molly Joann Russ Jan 2004

Escalation Bias In Group Decision-Making, Molly Joann Russ

LSU Master's Theses

The present study extended the literature on escalation bias to group decision-making in the context of performance appraisal. Escalation theory states that persons responsible for a hiring decision will provide higher evaluation ratings of that employee than those persons not responsible for the decision. This study compared the performance evaluation decisions of supervisors, individual team members, and teams in order to ascertain differences in escalation behaviors based on rater perspective and whether the rater was responsible for hiring the employee or not. Support for the hypotheses varied depending on the employment decision being made and the perspective of the decision-maker. …

Seismic Stratigraphic Investigation Of The Ukpokiti Field Channel Complex, Oml 108, Offshore Nigeria, Northwestern Niger Delta, Toby Latwan Stewart Jan 2004

Seismic Stratigraphic Investigation Of The Ukpokiti Field Channel Complex, Oml 108, Offshore Nigeria, Northwestern Niger Delta, Toby Latwan Stewart

LSU Master's Theses

Detailed seismic stratigraphic analyses and mapping show that a well defined Ukpokiti Field Channel complex (late Miocene) found on the up-thrown side of a major back-to-back fault system in the West Niger delta inner-continental shelf probably formed during a single eustatic fall. The channel (>500 msec, 10 km wide) shows several tributaries entering the trunk axis from what was probably a surface of subaerial exposure. Slumping is prominent on the north flank of the trunk channel. No channel unconformity is evident in the down-thrown block. This investigation seeks to resolve the lack of down-dip correlative seismic expression across the …

Innovative Cooling Configurations For Low Emission Gas Turbine Combustors, Ryan Thomas Hebert Jan 2004

Innovative Cooling Configurations For Low Emission Gas Turbine Combustors, Ryan Thomas Hebert

LSU Master's Theses

Presently, effective cooling of modern low NOx combustor liners is achieved through combinations of innovative impingement configurations and other heat transfer enhancement methods. An inherent characteristic of conventional impingement configurations is the occurrence of downstream heat transfer degradation due to increased crossflow effects. In the present study, two different impingement configurations are studied. Both impingement configurations examined in this study aim to increase heat transfer effectiveness by reducing the detrimental effects of spent air crossflow. In Part I, a combination technique wherein impingement is combined with ribs placed in between impingement rows is studied. Three configurations with increased rib placements …
