Experimental Analysis Of Aggression., Bethany Ann Marcus Jan 1997

Experimental Analysis Of Aggression., Bethany Ann Marcus

LSU Historical Dissertations and Theses

In 1982, Iwata, Dorsey, Slifer, Bauman, and Richman developed a systematic assessment method to identify the operant functions of self-injurious behavior. In this study, the Iwata et al., method was used to assess the operant functions of aggression displayed by children and adolescents with developmental disabilities. Although researchers have demonstrated that aggression serves operant functions, there has been no comprehensive analysis of aggression using the Iwata et al. method. Twelve children and adolescents participated. The experimental conditions from the Iwata et al. method were replicated (i.e., attention, instructional demand, play, no interaction); also, a tangible positive reinforcement condition was included …

Electrochemical And Spectroscopic Studies Of Boron And Sulfur Species In Nonaqueous Media., Jianzhong Liu

LSU Historical Dissertations and Theses

Room temperature molten salts have been of interest because of their unique properties such as aprotic nature and excellent Lewis acid-base adjustability. They provide a novel medium for fundamental studies and constitute a promising electrolyte for metal plating and secondary batteries. In the present study, the room temperature N-Butyl-pyridinium chloride (BPC)-boron trichloride (BCl$\sb3)$ and mixed BCl$\sb3$-AlCl$\sb3$-BPC melts have been prepared and characterized using reaction stoichiometries, electrochemistry and secondary ion mass spectrometry (SIMS). At normal atmosphere and room temperature, even when excess BCl$\sb3$ was added, BCl$\sb3$-BPC melts have a constant composition of 52:48 mole ratio BCl$\sb3$:BPC. SIMS studies confirmed previous Raman …

Technology In The English Composition Classroom: Freshman Composition Students Using The Internet To Plan Assignments And Conduct Research., Michael Allen Mccord Jan 1997

Technology In The English Composition Classroom: Freshman Composition Students Using The Internet To Plan Assignments And Conduct Research., Michael Allen Mccord

LSU Historical Dissertations and Theses

The use of computer and electronic communication and network technology is becoming increasingly important not only in society in general, but also in the college-level English composition classroom. These technologies amount to what some researchers term "multilayered literacies" or "new grammars." However, there have been few systematic studies of how students actually use these technologies. The current research presents a descriptive/naturalistic study of how students both learn and use the new electronic technologies as they accomplish research for, and respond to, a college-level writing assignment. This study examines the use of computers and networks by eight case study participants in …

Structural Equation Modeling Analysis Of Etiological Factors In Social Anxiety., Michele E. Mccarthy

LSU Historical Dissertations and Theses

The current study investigated possible etiological risk factors in the development of social anxiety. The risk factors examined in this study were family environment, negative peer interactions, neuroticism, self-perceived attractiveness, public self-consciousness, social behavior goal/ability discrepancy, and fear of negative evaluation. These variables were hypothesized to have both direct and indirect influences on the development of social anxiety. A hypothesized risk factor model was tested employing structural equation modeling (SEM) using questionnaire data collected from 559 college undergraduates. Phases of this study included the refinement of constructs, examination of the internal consistency and discriminant validity of the constructs, examination of …

Seasonal Changes In Gnrh Neurons And Effects Of Dietary Monoamine Precursors On The Hypothalamic-Gonadal Axis In House Sparrows (Passer Domesticus)., Christopher Andrew Meseke Jan 1997

Seasonal Changes In Gnrh Neurons And Effects Of Dietary Monoamine Precursors On The Hypothalamic-Gonadal Axis In House Sparrows (Passer Domesticus)., Christopher Andrew Meseke

LSU Historical Dissertations and Theses

Mechanisms modulating avian seasonal reproduction involve a complex interaction between exogenous environmental information and internal physiologic systems, such as functional changes in the hypothalamic-gonadal axis and changes in the influence of monoaminergic neurotransmitters on hypothalamic neuroendocrine cells. This project was undertaken to describe seasonal changes of the testes and immunoreactive-(ir)-gonadotropin-releasing hormone (GnRH) neurons in House Sparrows in southeastern Louisiana, and to examine the role of monoaminergic neurotransmitters in modulating seasonal reproduction through the use of dietary monoamine precursors. Testicular weights rapidly increased from February to March, peaked from April to July, when the seminiferous tubules were spermatagenically active and filled …

Analysis And Interpretation: Musical Analysis As A Technique For Performance Decisions In Selected Preludes By Claude Debussy., William Timothy O'Steen Jan 1997

Analysis And Interpretation: Musical Analysis As A Technique For Performance Decisions In Selected Preludes By Claude Debussy., William Timothy O'Steen

LSU Historical Dissertations and Theses

Thorough analysis will serve the performer as a valuable tool for making effective performance decisions. This study follows two guidelines: (1) analysis must include the examination of all elements of musical structure and (2) the performer must view the music from as many perspectives as possible, for example, as listener and analyst, as well as performer. In serving the second of these two guidelines, the study examines performance tradition as it pertains to Debussy's piano music, including historical performances of his contemporaries as well as Debussy's own recorded performances. A larger part of the study analyzes the structure of "Des …

Data Analysis Of The Allegro Gravitational Wave Detector., Evan Mauceli Jan 1997

Data Analysis Of The Allegro Gravitational Wave Detector., Evan Mauceli

LSU Historical Dissertations and Theses

The Allegro gravitational wave detector has been operational from 1991-1994, and 1996-present. We present a detailed description of the detector and the data acquisition system. Two distinct types of data analysis are detailed. First, we describe the search for burst sources of gravitational radiation. These are impulse forces acting on the bar, presumably from the stellar collapse associated with supernovae. Construction of the optimal filter for burst signals is described, as well as its application to the data from the detector. The uncertainties introduced into timing and signal strength estimates due to stationary noise are measured, giving the windows for …

The Third Way: A Study Of Economic Justice In The Writings Of Karol Wojtyla (Pope John Paul Ii)., Woodard King Mott Jr Jan 1997

The Third Way: A Study Of Economic Justice In The Writings Of Karol Wojtyla (Pope John Paul Ii)., Woodard King Mott Jr

LSU Historical Dissertations and Theses

Pope John Paul II, born Karol Wojtyla, has written extensively about the human person and how that person acts in the world. Beginning with Wojtyla's doctoral dissertation presented at the Pontifical University of St. Thomas Aquinas on the Catholic mystic St. John of the Cross and continuing through the most recent best seller, Crossing the Threshold of Hope, Christian personalism has pervaded Wojtyla's writings, encyclicals, and public utterances. Wojtyla's perspective on economic justice, as shaped by his Christian personalism, is the subject of this dissertation. A systematic investigation of Wojtyla's theory of economic justice reveals a third way of economic …

Modeling Hrm In Context: Examining The Role Of Human Resource Manager Discretion., Elyssa Blanton Schultz Jan 1997

Modeling Hrm In Context: Examining The Role Of Human Resource Manager Discretion., Elyssa Blanton Schultz

LSU Historical Dissertations and Theses

This dissertation presents a model focusing on human resource manager discretion and its role in influencing variations in HRM. Discretion, defined here as the latitude of action of human resource managers, is suggested as an important means of accounting for differing levels of constraint facing the HRM function. Because the model developed here focuses on discretion as a characteristic which is common to theories of choice and environmental determinism in organizational research, it is designed to stimulate future research that simultaneously considers predictions of HRM structure and content that have, to this point, been considered contradictory. In general, the results …

Photoemission Studies Of Magnetic Systems., Krishnan Subramanian Jan 1997

Photoemission Studies Of Magnetic Systems., Krishnan Subramanian

LSU Historical Dissertations and Theses

I have studied the electronic structure of thin films by photoelectron spectroscopy. My results show that even a monolayer film of Ni/Cu(001) exhibits bulk-like electronic structure and resembles that of bulk Ni. In order to better understand this result, I tracked the sp-band dimension at the Fermi surface of the Ni films for various coverages. For submonolayer coverages of Ni, the sp-band dimension was smaller than that of bulk Cu, but quickly reached that of bulk Ni by 1.2 ML Ni coverage. This continuous decrease implies a charge transfer from the Cu substrate to the Ni film, resulting in a …

Coupled Field Equations For Saturated Soils And Its Application To Piezocone Penetration And Shield Tunneling., Murad Yusuf Abu-Farsakh Jan 1997

Coupled Field Equations For Saturated Soils And Its Application To Piezocone Penetration And Shield Tunneling., Murad Yusuf Abu-Farsakh

LSU Historical Dissertations and Theses

An elasto-plastic coupled system of equations are formulated here in order to describe the time-dependent deformation of saturated cohesive soils. Formulation of these equations is based on the principle of virtual work and the theory of mixtures for inelastic porous media as proposed by Prevost (1980) and Kiousis and Voyiadjis (1988). The saturated soil is considered as a mixture consisting of two deformable media, the solid grains and the water. Each medium is regarded as a continuum and follows its own motion. The coupled equations are developed for large deformations with finite strains in an updated Lagrangian reference frame. The …

A Theory Of Cortical Neural Processing., David Timothy Young Jan 1997

A Theory Of Cortical Neural Processing., David Timothy Young

LSU Historical Dissertations and Theses

This dissertation puts forth an original theory of cortical neural processing that is unique in its view of the interplay of chaotic and stable oscillatory neurodynamics and is meant to stimulate new ideas in artificial neural network modeling. Our theory is the first to suggest two new purposes for chaotic neurodynamics: (i) as a natural means of representing the uncertainty in the outcome of performed tasks, such as memory retrieval or classification, and (ii) as an automatic way of producing an economic representation of distributed information. We developed new models, to better understand how the cerebral cortex processes information, which …

Evaluation Of Sampling Gear For Predicting Harvest Size, Yield And Incidence Of Stunting In Crawfish Ponds., Jimmy Lee Avery Jan 1997

Evaluation Of Sampling Gear For Predicting Harvest Size, Yield And Incidence Of Stunting In Crawfish Ponds., Jimmy Lee Avery

LSU Historical Dissertations and Theses

Dip-nets, test traps and experimental drop samplers were evaluated for their potential to predict crawfish (Procambarus spp.) yields and size distribution at harvest. Field studies were conducted at the Rice Research Station, LSU Agricultural Center, Crowley, Louisiana, between 1991 and 1996 in 82 (0.16-0.2 ha) earthen impoundments. Fields were managed to simulate rice-crawfish systems typical of the southwestern and south-central Louisiana. Multiple linear regression analysis was used to determine the relationship among catch-per-unit-effort (CPUE) of sampling gear (alone and in combination) with respect to yield in weight (kg/ha), yield in number (crawfish/ha) and size distribution at harvest. Relative abundance of …

The Sugar Masters: Slavery, Economic Development, And Modernization On Louisiana Sugar Plantations, 1820-1860., Richard J. Follett Jan 1997

The Sugar Masters: Slavery, Economic Development, And Modernization On Louisiana Sugar Plantations, 1820-1860., Richard J. Follett

LSU Historical Dissertations and Theses

In this dissertation, I contend that sugar planters in the antebellum South managed their estates progressively, efficiently, and with a capitalist political economy and ideology. By embracing slavery, technology, and a host of improvements, sugar planters strove to create integrated units producing, manufacturing, and marketing sugar on an agro-industrial scale. Despite a century of historiographical debate, historians remain divided over the incompatibility of slavery with industrial and agricultural innovation. Whether they look to Adam Smith or Karl Marx, most historians deem free labor a necessity for technology and growth. This, however, appears inaccurate, as antebellum sugar planters confidently advocated improvement …

Self-Mutilation In A Community Sample Of Adolescents., Elizabeth Eden Lloyd Jan 1997

Self-Mutilation In A Community Sample Of Adolescents., Elizabeth Eden Lloyd

LSU Historical Dissertations and Theses

The purpose of this study was to examine the provisional prevalence rates and characteristics of self-mutilative behavior in a community sample of adolescents. A total of 368 adolescents between the ages of 12 and 19 participated in this investigation. Thirty-nine percent of high school students sampled (n = 143) engaged in self-mutilation within the past year. Commonly endorsed behaviors were biting self, hitting self on purpose, and cutting/carving skin. Self-mutilators were likely to engage in these behaviors to reduce internal tension, as well as to gain attention. Self-mutilators were compared with non-mutilating adolescents (n = 225) on self-report measures of …

The Synthesis Of Novel Phosphine-Modified Ligands For Use In Bimetallic Hydroformylation., Howard Frederick Koch Iii Jan 1997

The Synthesis Of Novel Phosphine-Modified Ligands For Use In Bimetallic Hydroformylation., Howard Frederick Koch Iii

LSU Historical Dissertations and Theses

The tetraphosphine ligand, Et$\sb2$P(CH$\sb2)\sb2$P(Ph)CH$\sb2$P(Ph)(CH$\sb2)\sb2$PEt$\sb2 ,$ et,ph-P4, was designed to be a binucleating ligand for use in bimetallic hydroformylation catalysis. This ligand can be tailored for both electronic and steric factors at the internal and external phosphorus atoms. It is hoped that through careful tuning of this ligand, the rate and selectivity of our bimetallic catalyst can be optimized for various substrates. Modification of the original ligand may also lead us to a better understanding of the mechanism involved in the catalytic cycle. My goal has been to replace the phenyl substituents on the internal phosphorus atoms with various alkyl groups. …

The Preparation And Production Of Rapid Sequential Aiming Movements In Motor Control., Dongwon Yook Jan 1997

The Preparation And Production Of Rapid Sequential Aiming Movements In Motor Control., Dongwon Yook

LSU Historical Dissertations and Theses

Three experiments are reported that attempt to further our knowledge of the preparation and production of rapid sequential aiming movements. Specifically, these experiments examined possible reasons why in sequential aiming responses, the second movement segment (MT2) is consistently performed more slowly than first and third movement segments (MT1 and MT3). In the first experiment, participants struck 1, 2, or 3 targets in sequence without the benefit of visual feedback and without time stress to determine if MT2 is slowed due to a visually based on-line trajectory-correction process. The results showed that MT2 was not slower than MT1 under these condition. …

Technical Training Program Evaluation: Present Practices In United States' Business And Industry., Skip Twitchell Jan 1997

Technical Training Program Evaluation: Present Practices In United States' Business And Industry., Skip Twitchell

LSU Historical Dissertations and Theses

There is a lack of information on training evaluation. For those studies addressing the amount of evaluation that occurs and in which samples can be identified, the samples are non-random. There have been very few reports on the methods used for evaluation or the reasons why there is so little evaluation. This study used a random sample selected from members of the ASTD professional practice area titled, Technical and Skills Trainers. It can be argued that this is an informed sample involved in a training area that produces objective outcomes and should produce a favorable picture of training evaluation. Questions …

The Role Of Binge Eating Disorder In The Estimation Of Food Intake Of Obese Individuals., Drew Arthur Anderson Jan 1997

The Role Of Binge Eating Disorder In The Estimation Of Food Intake Of Obese Individuals., Drew Arthur Anderson

LSU Historical Dissertations and Theses

Individuals with binge eating disorder (BED) share some characteristics with persons with bulimia nervosa (BN) and some characteristics of obese persons who do not have problems with binge eating. Previous studies have found that while nonbinging individuals underestimate caloric intake, patients with BN overestimate caloric intake when intake is large. The present study hypothesized that because persons with BED binge eat, they would also overestimate caloric intake. A total of 56 women (9 with BED, 23 obese nonbingers, and 24 normal weight nonbingers) estimated several portion sizes of ice cream and then ate a test meal of ice cream and …

Relationship Of Self-Injurious Behavior And Aggression To Social Skills In Persons With Severe And Profound Mental Retardation., Dee Duncan Jan 1997

Relationship Of Self-Injurious Behavior And Aggression To Social Skills In Persons With Severe And Profound Mental Retardation., Dee Duncan

LSU Historical Dissertations and Theses

In the literature, self-injurious behavior and aggression are often lumped together collectively as maladaptive behaviors. This study examined the social skills characteristics between persons with self-injurious behavior, aggression and a control group using the Matson Evaluation of Social Skills in Persons with Severe and Profound Retardation (MESSIER). Persons engaging in self-injurious behavior were significantly different from persons engaging in aggression as well as from the control group on five of the six subscales. The self-injury group had lower scores on subscales measuring positive behaviors and higher scores on subscales measuring negative behaviors. As expected for persons engaging in aggression, scores …

Magnetic Measurements On Superconductors And Heavy Fermions., Donavan Weslee Hall Jan 1997

Magnetic Measurements On Superconductors And Heavy Fermions., Donavan Weslee Hall

LSU Historical Dissertations and Theses

Magnetization and de Haas - van Alphen (dHvA) measurements have been made on the high temperature superconductor Ba$\sb{0.6}$K$\sb{0.4}$BiO$\sb3$ and the heavy fermion CeB$\sb6$. First ever observations of the dHvA effect in Ba$\sb{0.6}$K$\sb{0.4}$BiO$\sb3$ are reported. Two dHvA spectrometers (pulsed field and field modulation) were used to measure two samples. Four frequencies are found in the field modulation data with the 11.6 kT orbit in good agreement with band structure calculations. The three lowest frequencies were measured with the pulsed field spectrometer. All dHvA measurements were made in the superconducting mixed state. These measurements indicate that Ba$\sb{0.6}$K$\sb{0.4}$BiO$\sb3$ has a Fermi surface. Magnetization …

Teacher Conceptions And The Curriculum: A Longitudinal, Multicase Study Of College Chemistry Teaching., Charles J. Killebrew

LSU Historical Dissertations and Theses

Strategic innovations and interventions to reform college science teaching will be required to promote the retention and achievement of those students who might otherwise elect to defect at the entry-level courses. The extent to which this can be achieved will depend upon educational research into ways that the science curriculum can be restructured to accomplish the dual function of enhancing science literacy while promoting recruitment to scientific careers. To explore these issues, four introductory college chemistry classes were observed over a period of two years. The classes were designated either as traditional or conceptual. Selection into these categories was based …
