Atmosphere Effects Revisited: The Effect Of Atmosphere On Judgments Of Validity Using Thematic Syllogisms., Roberta Elizabeth Love Jan 1998

Atmosphere Effects Revisited: The Effect Of Atmosphere On Judgments Of Validity Using Thematic Syllogisms., Roberta Elizabeth Love

LSU Historical Dissertations and Theses

Syllogisms having conclusions consistent with atmosphere are shown to be accepted at significantly higher rates than those having conclusions inconsistent with atmosphere. Furthermore, there is strong evidence that the dual influences of quality and quantity, independently affect acceptance rates. The first experiment also indicates a main effect of gender on acceptance rates to certain invalid syllogisms (those with conclusions inconsistent with quality, or quantity, or both). The second experiment replicates the atmosphere effect found in the first experiment and extends it to valid syllogisms and indeterminate invalids consistent with both quality and quantity. It also proposes an alternative to the …

Sample-Based Forest Landscape Diversity Indices., Bernard Ross Parresol Jan 1998

Sample-Based Forest Landscape Diversity Indices., Bernard Ross Parresol

LSU Historical Dissertations and Theses

Studies of spatial patterns of landscapes are useful to quantify human impact, predict wildlife effects, or describe various landscape features. A robust landscape index should quantify two distinct components of landscape diversity: composition and configuration. One category of landscape index is the contagion index. A generalized measure of contagion is defined as a function of concentration. From this definition two contagion indices, $\Gamma\sb1$ (a new index) and $\Gamma\sb2$ (an entropy formulation), are derived from expected values of geometric random variables. A widely used relative contagion index, $RC\sb2,$ is shown to be a scaled version of $\Gamma\sb2.$. Distributional properties of $\\Gamma\sb1,\ …

Characterization And Biodegradation Of Crawfish And Agricultural Processing By-Product Compost., Mounir Yehia Minkara Jan 1998

Characterization And Biodegradation Of Crawfish And Agricultural Processing By-Product Compost., Mounir Yehia Minkara

LSU Historical Dissertations and Theses

Disposal of crawfish processing wastes poses a challenging problem to the rapidly expanding crawfish industry. Co-composting is examined as a waste management alternative to landfill disposal. Wood chips, rice hulls, bagasse, and bark were evaluated for use as bulking agents in composting crawfish processing residuals. Use of bagasse as a bulking agent led to the largest reduction in volatile solids, organic-C, particle size, and compost volume. Finished compost using bagasse contained the greatest concentration of N. Self-heating patterns and decomposition of crawfish residuals were satisfactory using all four bulking agents. The finished products of all compost mixtures were stable and …

The Effect Of Pulmonary Infection (Actinobacillus Pleuropneumoniae), Endotoxin And Dexamethasone On Enrofloxacin Pharmacokinetic Parameters In Swine., Lynn O. Post Jan 1998

The Effect Of Pulmonary Infection (Actinobacillus Pleuropneumoniae), Endotoxin And Dexamethasone On Enrofloxacin Pharmacokinetic Parameters In Swine., Lynn O. Post

LSU Historical Dissertations and Theses

Efficacy studies are often done on diseased animals while pharmacokinetic studies are done on healthy animals. Disease models are inherently difficult to standardize because of the many variables associated with measuring pharmacokinetic parameters in abnormal animals. Information derived from pharmacokinetic studies with diseased animals could be useful to determine if therapeutic doses of a drug or antimicrobial becomes less effective or toxic due to changes in distribution and clearance. The objectives of this study were to: characterize a pulmonary infection model in swine using Actinobacillus pleuropneumoniae; evaluate the pharmacokinetic changes associated with the pulmonary infection model and dexamethasone after the …

Albert Camus's Reconstruction Of Symbolic Reality: Exile, Judgment, And Kingdom., Peter Alan Petrakis Jan 1998

Albert Camus's Reconstruction Of Symbolic Reality: Exile, Judgment, And Kingdom., Peter Alan Petrakis

LSU Historical Dissertations and Theses

Throughout his life, Albert Camus was deeply concerned with problems of language and representation. Often mislabeled an existentialist or philosopher of the absurd, his skepticism of modern rationality has been well recorded. Yet despite considerable scholarly attention, a satisfactory understanding of Camus's thoughts on language has not been achieved. This essay is an effort to rectify the situation by carefully exploring Camus's use and understanding of symbols. By first gleaning a theory of symbolization from the philosophical works of Ernst Cassirer, Eric Voegelin, and Paul Ricoeur, and then comparing it to Camus's writings on myth, symbols, and narrative, it is …

Daniel Defoe's "An Essay On The History And Reality Of Apparitions": A Critical Edition., Kathleen Louise Kincade Jan 1998

Daniel Defoe's "An Essay On The History And Reality Of Apparitions": A Critical Edition., Kathleen Louise Kincade

LSU Historical Dissertations and Theses

This dissertation is a scholarly edition of Daniel Defoe's An Essay on the History and Reality of Apparitions, which was published in 1727 and has never been re-edited since his death in 1731. It poses several interesting problems for both the literary critic and bibliographer. This edition is challenging for the bibliographer because, initially, this work was published anonymously. The second edition appeared with the addition of "by Andrew Moreton, Esq." as author. A section of my introduction attributes this work to Defoe by using contemporary theory and methods. Defoe scholars have had a problem attributing works to Defoe. Instead …

Leisure-Time Physical Activity As A Moderator Of The Association Between Stress And Depression Among Low-Income Primary Care Female Population., Isabel Cristina Scarinci Jan 1998

Leisure-Time Physical Activity As A Moderator Of The Association Between Stress And Depression Among Low-Income Primary Care Female Population., Isabel Cristina Scarinci

LSU Historical Dissertations and Theses

The present study used a longitudinal design in an attempt to answer the following questions: (a) what is the prevalence of sedentary lifestyle in a low-income primary care female population? (b) does minor stress predict depressive symptoms after controlling for major stress? and (c) does leisure-time physical activity moderate the association between stress and depressive symptoms? The sample included 150 randomly selected adult female patients recruited from primary care clinics at a public hospital in the state of Louisiana. This sample consisted predominantly of uninsured, African American, low-income, middle-aged females. The results indicated that prevalence of sedentary lifestyle (58%) was …

Gendered Experiences Of Public Accounting Firms: Organizational Commitment And Intentions To Leave., Harriet Lynn Stallworth Jan 1998

Gendered Experiences Of Public Accounting Firms: Organizational Commitment And Intentions To Leave., Harriet Lynn Stallworth

LSU Historical Dissertations and Theses

The under representation of female public accountants in the upper echelons of public accounting organizations is recognized as problematic by both these firms and the accounting profession. The problem is confounded by women's higher turnover rate at each organizational level within these firms. The purpose of this study is to examine women's and men's experiences of the public accounting work environment in order to provide some insight into why women are more likely to leave these firms. The research questions to be addressed are (1) whether, and specifically, how, do males' and females' experiences of the public accounting work environment …

Gaining And Controlling Access To The Arena: Stories Of Ties In A Technological Dispute., Tobias Albert Ten Eyck Jan 1998

Gaining And Controlling Access To The Arena: Stories Of Ties In A Technological Dispute., Tobias Albert Ten Eyck

LSU Historical Dissertations and Theses

This is a study of the stories told about distribution of resources and structural constraints which operate within newspaper arenas that were experienced by reporters and sources involved in coverage of food irradiation between 1987 and 1996 at two regional newspapers (Louisiana and Florida). Using an unstructured interview instrument, I conducted interviews with 40 sources and 12 newspaper reporters, which I used to construct a framework in which to show how cultural, economic and social capital are used for getting and blocking action in the newspaper arenas. These interviews show that while cultural capital was the most prominent type of …

Continued Consequences Of Race-Based Redistricting: An Analysis Of Incumbent Roll-Call Voting Behavior And Candidate Emergence In The 1990s., Christine Leveaux Sharpe Jan 1998

Continued Consequences Of Race-Based Redistricting: An Analysis Of Incumbent Roll-Call Voting Behavior And Candidate Emergence In The 1990s., Christine Leveaux Sharpe

LSU Historical Dissertations and Theses

There have been many claims made that the creation of the majority-black district has led to a more conservative Congress, both in terms of roll-call voting behavior and partisan membership. I contend that there is a direct relationship and an indirect relationship between the creation of majority-black districts and increased conservatism in the House. The direct relationship focuses on the roll-call voting behavior of the House member. The indirect relationship focuses on the partisan makeup of the House. The analysis is couched in broad-based rational choice theory, asserting that incumbent House members and prospective House candidates behave strategically in an …

A Model-Driven Simulation Study Of World-Wide-Web Cache Policies., Ying Shi Jan 1998

A Model-Driven Simulation Study Of World-Wide-Web Cache Policies., Ying Shi

LSU Historical Dissertations and Theses

The World-Wide-Web has experienced exponential growth in recent years. This growth has created a tremendous increase in network and server loads that have subsequently adversely affected user-response times. Among many viable and available approaches to reducing user-response time, Web caching appears to be one approach that has recently received considerable attention. In this dissertation we explore a new approach to the study of Web cache policies, namely model-driven simulation. We present a good model of Web-access user patterns based on sound theory and principles from the information sciences. This model is justified by the empirical web access data from several …

Autobiography From St. Augustine To David Antin: Examining The Construction Of The Self As Mutually Reflective Of Cultural Developments In Science And Technology, Art, And Literary Theory., Jessica Lynn Faust Jan 1998

Autobiography From St. Augustine To David Antin: Examining The Construction Of The Self As Mutually Reflective Of Cultural Developments In Science And Technology, Art, And Literary Theory., Jessica Lynn Faust

LSU Historical Dissertations and Theses

In this study, I look at the mutually reflective changes in society and autobiography in works definitive for their various periods: Augustine's The Confessions from antiquity; Rousseau's The Confessions from the eighteenth century; the autobiographical writings of Gertrude Stein, from the modernist period; and, most importantly here, the focus on the development of David Antin's work as representative of both postmodernism and current culture. Specifically, I consider the construction of the self in respect to art, literary theory, memory research, and science and technology. During the second half of the twentieth century, computers have permeated almost every facet of society. …

Reasonable Employment Accommodations For Persons With Disabilities: A Policy-Capturing Approach., Heather A. Honig Jan 1998

Reasonable Employment Accommodations For Persons With Disabilities: A Policy-Capturing Approach., Heather A. Honig

LSU Historical Dissertations and Theses

Title I of the Americans with Disabilities Act of 1990 (ADA) requires employers to provide reasonable accommodations to qualified persons with disabilities who need them in order to work (EEOC, 1992). The ADA defines reasonable accommodation ambiguously. The current study used a policy capturing approach to examine the effects of characteristics of the person with a disability (i.e., type of disability, previous performance level, employment status), characteristics of the accommodation (i.e., cost, type of accommodation), and characteristics of the observer (i.e., occupational status, disability status, gender) on judgments of reasonable accommodation. Students and employed persons (n = 107) completed the …

Rousseau And The Lyric Natural: The Self As Representation., Pamela Diane Gay Jan 1998

Rousseau And The Lyric Natural: The Self As Representation., Pamela Diane Gay

LSU Historical Dissertations and Theses

Jean-Jacques Rousseau's work for the lyric stage comprises several opera libretti (Les Muses galantes and La Decouverte du nouveau monde), an intermede ( Le Devin du village), a scene lyrique ( Pygmalion) and an unfinished opera (Daphnis et Chloce ). These works use as a motif the figure of nature while continually defining and redefining, in a sort of spiral development, the self. Nature represents for Rousseau and others of his century a paradigm allowing for small segments of history to be presented as an evenly construed narrative. For Rousseau, the construction of a narrative in Le Second Discours marks …

A Brief Method For Evaluating The Effects Of Stimulant Medication And Behavioral Interventions On The Classroom Performance Of Children With Attention Deficit Hyperactivity Disorder (Adhd)., Veronica Schilling Gulley Jan 1998

A Brief Method For Evaluating The Effects Of Stimulant Medication And Behavioral Interventions On The Classroom Performance Of Children With Attention Deficit Hyperactivity Disorder (Adhd)., Veronica Schilling Gulley

LSU Historical Dissertations and Theses

This study examined the separate and combined effects of varying dosages of methylphenidate (MPH) and behavioral interventions of varying strengths on the disruptive behavior and academic performance of 5 students with attention deficit hyperactivity disorder (ADHD). Overall results indicated the behavioral interventions at some level were comparable to previously prescribed dosages of MPH for decreasing disruptive classroom behavior for 4 of 5 participants. However, the "strength" of behavioral intervention necessary to achieve maximum improvements was idiosyncratic. For a fifth participant, results indicated that MPH was not necessary. Results also demonstrated that the combination of the behavioral interventions at some level …

A Study Of Pore Fluids And Barite Deposits From Hydrocarbon Seeps: Deepwater Gulf Of Mexico., Baoshun Fu Jan 1998

A Study Of Pore Fluids And Barite Deposits From Hydrocarbon Seeps: Deepwater Gulf Of Mexico., Baoshun Fu

LSU Historical Dissertations and Theses

The primary goals of this research were to (i) determine the factors controlling the chemical compositions of pore fluids in hydrocarbon seep sediments of the Gulf of Mexico, and (ii) delineate the nature, age and origin of barite deposits associated with seeps. Three types of pore fluids from seeps have been discerned: (i) sediment-trapped seawater; (ii) brines derived by seawater dissolution of subsurface salt diapirs; and (iii) deep-seated formation waters enriched in Ba and Ra. The Ra-enriched formation waters advecting to the seafloor may explain why 226Ra levels in the Gulf of Mexico water column are higher than in the …

Computer-Assisted Instruction: Enhancements For Language-Learning Applications., William Lawrence Harrell Jr Jan 1998

Computer-Assisted Instruction: Enhancements For Language-Learning Applications., William Lawrence Harrell Jr

LSU Historical Dissertations and Theses

Presently, computer-assisted instruction is in use in many educational venues. Unfortunately, the application of computer-assisted language learning at a distance has virtually been ignored. This is an opportunity that needs to be explored. In order to do so, a number of considerations must be attended to. First, effective monitor display design is critical for the optimal presentation of distance learning material. Second, gender and equity factors that impact computer use must be understood to minimize the detrimental effects they might have on computer-assisted distance learning. Third, the needs of students involved with the particularly-demanding application of distance learning principles of …

Determination Of Optimal Composition Of Stabilized Phosphogypsum Composites For Saltwater Application., Tingzong Guo Jan 1998

Determination Of Optimal Composition Of Stabilized Phosphogypsum Composites For Saltwater Application., Tingzong Guo

LSU Historical Dissertations and Theses

Phosphogypsum (CaSO4 ˙ 2H2O, PG), a solid by-product of phosphoric acid production, has been classified as a "Technologically Enhanced Natural Radioactive Material" (TENR), because it contains radionuclides (eg., radium 226) and some trace toxic metals in concentrations, which may pose a potential hazard to human health and the environment. The current regulated disposal method for PG is on-site stockpiling, which has created a serious environmental management problem. An appealing solution to the problem is the use of stabilized PG for aquatic enhancement activities. This solution can eliminate the airborne vector of transmission for radon 222 and therefore may provide a …

Factors Affecting Root Colonization By Calonectria Ilicicola And Development Of Red Crown Rot Disease On Soybean., Pali Upulmathie De Silva Kuruppu Jan 1998

Factors Affecting Root Colonization By Calonectria Ilicicola And Development Of Red Crown Rot Disease On Soybean., Pali Upulmathie De Silva Kuruppu

LSU Historical Dissertations and Theses

Red crown rot of soybean caused by Calonectria ilicicola is a serious disease in Louisiana. The pathogen infects soybean roots and the above ground symptoms and signs appear during reproductive stages of the plant. Little information is available on root infection as well as effects of environmental factors or varietal resistance on this process. Field studies were conducted in 1994, 1995, and 1996 to determine the effects of planting date, cultivar susceptibility, and soil pathogen population on soybean root colonization by C. ilicicola and subsequent disease development. Early season colonization of tap as well as lateral roots was important for …

The Conversion Of Light Amines Over Copper-Containing Zeolites., Trent Francis Guidry Jan 1998

The Conversion Of Light Amines Over Copper-Containing Zeolites., Trent Francis Guidry

LSU Historical Dissertations and Theses

Copper-containing zeolites have been prepared by vapor, aqueous, and solid-state ion-exchange, characterized, and investigated for the conversion of light amines. A copper-containing zeolite was synthesized by vapor ion-exchange in this study by a method that does not appear to have been previously reported. This material was prepared by reaction of the acidic zeolite with CuCl vapor, followed by oxidation of the Cu+ ions to copper oxonium. ions which are converted to copper hydroxyl dimers on exposure to air. The copper hydroxyl dimer exchanged zeolite is stable in air and can be converted back to a highly exchanged Cu+ zeolite by …

Comparison Of Intervention Strategies Based On Experimental Analysis, Descriptive Analysis, And Reinforcer Assessment In Addressing Off-Task Classroom Behaviors., Lynn Habyan Lafleur Jan 1998

Comparison Of Intervention Strategies Based On Experimental Analysis, Descriptive Analysis, And Reinforcer Assessment In Addressing Off-Task Classroom Behaviors., Lynn Habyan Lafleur

LSU Historical Dissertations and Theses

Independent descriptive and experimental analyses as well as preferences assessments, were conducted. Descriptive analyses were conducted to identify baseline levels of off-task behavior, and to systematically describe the co-variation between off-task behaviors and peer attention, teacher attention, and the instructional task. Data on off-task behavior were analyzed by computing conditional probabilities associated with maintaining stimuli (e.g., peer attention). Intervention development was based on a simple contingency reversal. Experimental analyses were conducted to examine the extent to which off-task behavior was related to task difficulty or to consequences (i.e., peer attention) that were systematically programmed by the experimenter. Hypotheses and intervention …

Analog Functional Assessment In General Education Settings., James Alfred Levelle Jan 1998

Analog Functional Assessment In General Education Settings., James Alfred Levelle

LSU Historical Dissertations and Theses

Persistent disruptive behaviors in school classrooms often result in referrals for behavior intervention services. Although research has supported several intervention strategies, limited research has focused on linking assessment to the selection of specific strategies. Experimental analysis procedures for assessing the function of behavior have been successful in the selection of specific strategies with developmentally disabled students and in special education environments. However, research in general education settings has been sparse. In this study, an analog functional assessment approach utilizing experimental analysis procedures was conducted to assess the function of off-task behaviors in regular education settings. Conditions were established in each …

Half Empty Or Half Full: Explaining Black Attitudes Toward Affirmative Action., Maruice Louis Mangum Jan 1998

Half Empty Or Half Full: Explaining Black Attitudes Toward Affirmative Action., Maruice Louis Mangum

LSU Historical Dissertations and Theses

Using the Black National Election Study series (1984, 1988, and 1996), I estimate black support for affirmative action. I develop models that capture the effects of self-interest (as reflected in socioeconomic and demographic characteristics, and perceptions of both racial threat and racial fairness) and symbolic politics attitudes (the core values of egalitarianism and individualism, political ideology, partisanship, and group consciousness). The method of choice is Ordinary Least Squares Estimation. An examination of the data shows that what drives black attitudes toward affirmative action are largely symbolic politics attitudes, not the effects of self-interest. Generally speaking, the theory of symbolic politics …

Autobiographical Memory In Mild And Moderate Dementia Of The Alzheimer's Type., Judith Parks Levy Jan 1998

Autobiographical Memory In Mild And Moderate Dementia Of The Alzheimer's Type., Judith Parks Levy

LSU Historical Dissertations and Theses

Alzheimer's disease (AD) is a progressive disease that particularly affects memory with difficulties starting insidiously and gradually progressing. Anterograde amnesia for semantic and episodic types of declarative knowledge becomes the most prominent and disproportionately impaired cognitive symptom. By the middle stages of the disease, this memory loss progresses to severe impairment. The neuropathology of early AD involves the hippocampal complex, which is involved in new learning and storage of recent experiences. As the disease progresses, it involves neocortical areas, which are involved in the storage of more remote memories. Participants, including minimal stage AD, mild stage AD, moderate stage AD, …

School Desegregation From Brown To Fordice, 1954-1992: A Case Study In American Individualism., Albert Leon Samuels Jan 1998

School Desegregation From Brown To Fordice, 1954-1992: A Case Study In American Individualism., Albert Leon Samuels

LSU Historical Dissertations and Theses

In United States v. Fordice (1992), the Supreme Court declared that racially nondiscriminatory admissions and hiring policies alone failed to satisfy the state of Mississippi's "affirmative duty" to dismantle a previously de jure system of segregated higher education. However, the justices declined to define precisely what the state must do to satisfy its constitutional obligations, leaving in its wake a host of unresolved questions. Of particular concern to many African Americans is the fact that the future status of public black universities was left in the balance. Using a case study approach, this dissertation argues that higher education desegregation cannot …

Vocational Education And Recidivism At The Louisiana Correctional Institute For Women., Henry Elbert Sanders Jr Jan 1998

Vocational Education And Recidivism At The Louisiana Correctional Institute For Women., Henry Elbert Sanders Jr

LSU Historical Dissertations and Theses

Recidivism is a phenomenon causing growing concern. When released criminals return to crime, the costs become immeasurable. Victims can never be adequately compensated for personal losses, and the nation cannot halt the spiraling costs of maintaining prisons housing mostly repeat offenders. The nation is spending upwards from 98 billion dollars on crime, annually. Public opinion opposes education for inmates, yet, with the nation's prisons operating near capacity, a millennium approaches that promises another wave of prison construction resulting in exponential leaps in the costs of incarceration. A marketing concept asserts that attracting people to a product is half the battle. …

The "Power...To Alter And Amend": Textual Production And Editorial Actions In Samuel Richardson's "Clarissa"., Steven Robert Price

LSU Historical Dissertations and Theses

This dissertation is a study of texts, focusing on how texts are constructed (through both words as well as physical attributes) and how they are edited after their initial composition. The scope of this dissertation is limited to Samuel Richardson (1689-1761) and his rare 1750 third edition of Clarissa and to the characters in Clarissa and their familiar letters. I argue that the altering of a text is a negotiation of power between the editor and the author, and that editors advance their personal agendas by undermining the intentions of the author. In Chapter 1, I explain the relevancy of …

A Social Cognitive Theory Model Of Salesperson Performance., Robert Chapman Mcmurrian Jan 1998

A Social Cognitive Theory Model Of Salesperson Performance., Robert Chapman Mcmurrian

LSU Historical Dissertations and Theses

A primary objective of marketing practitioners, especially sales managers in organizations with personal selling functions and salesforces, has been an understanding of the factors related to effective sales performance. Much of the current research dedicated to understanding these factors has been grounded in Vroom's expectancy theory. Expectancy theory posits that successful performance of a task is a function of the level of effort that a person expends on the task. There are three factors that influence this level of effort: (1) an expectation that effort will result in better task performance; (2) a belief that better performance will result in …
