Theoretical And Pedagogical Applications Of Discourse Analysis To Professional Writing., Kim Sydow Campbell Jan 1990

Theoretical And Pedagogical Applications Of Discourse Analysis To Professional Writing., Kim Sydow Campbell

LSU Historical Dissertations and Theses

This dissertation attempts to show the utility of discourse analysis for professional writing. The articles collected here fall into three categories: Chapter One provides an overview of the need for a discourse analysis approach in writing research; Chapters Two and Three demonstrate applications of Speech Act Theory to problems in tone; and Chapters Four, Five and Six suggest the role that cohesion and coherence play in professional writing. Chapter One notes that, with the emphasis on process, discourse based research has largely fallen out of favor with writing specialists. Despite this lack of enthusiasm, this chapter demonstrates the importance of …

Sympathy, Gender, And The Writing Of Value In Late Eighteenth Century English Letters., Lucinda Cole Jan 1990

Sympathy, Gender, And The Writing Of Value In Late Eighteenth Century English Letters., Lucinda Cole

LSU Historical Dissertations and Theses

This study of sympathy is best described as an historically-grounded feminist critique in response to a contemporary critical debate. Recently, "sympathy," "compassion," and "care" have been promoted by many scholars interested in positing alternatives to a clearly masculinist ethical tradition derived from Kant, Hegel, and others. Yet missing from this work is a critical examination of the ethical tradition extending from Hume's writings in the eighteenth century to Max Scheler's in our own. My major purpose within this context is to demonstrate how sympathy functions as a major term in systems of value no less male-biased than the ethics of …


Age Of Onset And Duration Variables: Relationship To Primary And Secondary Psychopathology Of Bulimia Nervosa., Darlene Broussard Witcher Jan 1990

Age Of Onset And Duration Variables: Relationship To Primary And Secondary Psychopathology Of Bulimia Nervosa., Darlene Broussard Witcher

LSU Historical Dissertations and Theses

Over the past decade there has been growing concern about the syndrome of bulimia nervosa. Current theoretical models of the etiology and symptomatology of bulimia predict that the psychopathology of the eating disorder worsens over time. The specific purposes of this study was to examine the effect of onset age and duration of the disorder on the primary and secondary psychopathology of bulimia nervosa at the time of presentation for treatment. The results suggest that binging and purging worsen with increasing duration and older age of onset, accompanied by increased weight and greater distortion of body size estimation. Furthermore, subjects …


The Relationship Of Serum Killing, Phagocytosis And Oxidant Production By Bovine Monocyte-Derived Macrophages To Intracellular Survival Of Brucella Abortus., Denise Ida Bounous Jan 1990

The Relationship Of Serum Killing, Phagocytosis And Oxidant Production By Bovine Monocyte-Derived Macrophages To Intracellular Survival Of Brucella Abortus., Denise Ida Bounous

LSU Historical Dissertations and Theses

Functional activities of monocyte-derived macrophages and serum killing ability in a population of Brucella abortus-naive cows were evaluated. The ability of these macrophages to phagocytize and control intracellular survival of B.abortus and to produce oxidant was measured. Fresh normal bovine sera killed significantly more B.abortus than reactor serum or fetal bovine serum. When heated to destroy complement, none of the sera were capable of significant killing. The ability of sera from B.abortus-naive cows to kill the bacteria was normally distributed, with all animals within $\pm$ 2 sd of the mean. Phagocytosis of bacteria opsonized with autologous or reactor sera was …


The Social Integration-Deviance Hypothesis In Sociology: The Case Of Teenage Fertility., Stephen Joseph Caldas Jan 1990

The Social Integration-Deviance Hypothesis In Sociology: The Case Of Teenage Fertility., Stephen Joseph Caldas

LSU Historical Dissertations and Theses

The purpose of this dissertation is to construct and test an elaborated version of the social integration-deviance model. Social integration theory traces its origins to Emile Durkheim, who postulated the existence of two forms of social integration, today known as normative and functional integration. In his classic work Suicide (1897/1951) Durkheim first empirically tested his theory of social integration, though arguably only for normative integration. Others have since elaborated on his theory, and have tested various versions of it (Hirschi, 1969; Collette, Webb, & Smith, 1979). The current work conceptualizes teenage childbearing in the United States as deviancy from an …


Evaluation Of Selected Pulmonary Function Tests In Resting Thoroughbred Horses Having Reversible, Experimentally Induced Respiratory Dysfunctions., Alan John Guthrie Jan 1990

Evaluation Of Selected Pulmonary Function Tests In Resting Thoroughbred Horses Having Reversible, Experimentally Induced Respiratory Dysfunctions., Alan John Guthrie

LSU Historical Dissertations and Theses

The purpose of the first part of this study was to develop computerized techniques for automation of instrument calibration, data collection and calculation of indices of pulmonary mechanical function in resting and exercising horses. The microcomputer system developed enabled a single trained technician to reliably operate the equipment in an equine pulmonary mechanics laboratory. The first experiment investigated the temporal effects of histamine and methacholine aerosols on indices of pulmonary mechanics derived from the linear equation of motion. Data calculated on a breath-by-breath basis were too variable to be reliably modeled. Following application of averaging techniques, the temporal effects of …


Beta-Endorphin Receptors On Equine Lymphocytes: Relationship To Immune Function And Exercise., Jena Gosselink Hamra Jan 1990

Beta-Endorphin Receptors On Equine Lymphocytes: Relationship To Immune Function And Exercise., Jena Gosselink Hamra

LSU Historical Dissertations and Theses

Current evidence suggests that endogenous opioids are released in response to various stressors and that these opioids interact with cells of the immune system, and modulate immune function. However, data substantiating this are conflicting. Therefore, this study endeavored to clarify the role of beta-endorphin (BE) in exercise and immune function. Beta-endorphin exhibited a diurnal rhythm in the horse with peak plasma levels occurring at 0900 hours. Analgesia, tachycardia and mydriasis were also observed at this time, mimicking the effects of morphine in the horse. Therefore, subsequent experiments were performed at 0900 hours during times of increased basal opioid activity. Beta-endorphin …


Assessment Of Athletic Potential And Augmentation Of Performance In Thoroughbred Racehorses., John Daniel Harkins Jan 1990

Assessment Of Athletic Potential And Augmentation Of Performance In Thoroughbred Racehorses., John Daniel Harkins

LSU Historical Dissertations and Theses

The purposes of this dissertation were to (1) determine running abilities of horses on the racetrack, (2) design treadmill standard exercise tests (SETs) to measure exercise variables that correlate with racetrack performance, and (3) assess the influence of training, competition, and ergogenic aids on performance. Run times of 25 Thoroughbreds were determined during solo and competitive track runs of 1200, 1600, and 2000 meters. Cardiac, respiratory, and hematologic variables were later measured during treadmill SETs. Variables were correlated with average run times. Heart rate scores, V$\sb{200}$, plasma lactate values, and maximal oxygen uptake correlated best with performance. Interval and conventional …


Effects Of Gel Teat Cleaning And Sanitizing On Raw Milk Quality And Udder Health., Kasimu Hudu Ingawa Jan 1990

Effects Of Gel Teat Cleaning And Sanitizing On Raw Milk Quality And Udder Health., Kasimu Hudu Ingawa

LSU Historical Dissertations and Theses

Thirty lactating Holstein cows were divided into three groups of ten each and assigned to three treatments. The first treatment required using a gel teat sanitizer cleaner (GEL) and paper towels, no water to clean teats prior to milking. The second used only water (WASH) and paper towels, and the third used water, paper towels, and predipping (PREDIP) with 0.5% iodophor solution. Individual cow samples of milk were aseptically collected weekly from weigh jars for ten weeks. Bacteria counts were determined. Microorganism counts were also monitored from individual cow teat swabs. Treatment effects on daily milk yield, fat and protein …


The Relations Between Stress, Mood And Insomnia., Susan Rubman Jan 1990

The Relations Between Stress, Mood And Insomnia., Susan Rubman

LSU Historical Dissertations and Theses

Stress is hypothesized to cause increased cognitive and physiological arousal which is incompatible with sleep. Major life events have been implicated as a significant factor in the onset of chronic insomnia (Healey et al., 1981), and there is some suggestion that minor life events influence symptoms as well (Haynes et al., 1981). The present study was designed to evaluate and further clarify the role of daily minor stressors and mood variables on sleep in both normal sleepers and insomniacs. Subjects with insomnia secondary to medical or physical disorders were excluded from this study. Fifty-four adult subjects (20 mixed-complaint insomniacs, 17 …


Effects Of Artificial Mineral Licks On White-Tailed Deer., Stephen Redmore Schultz Jan 1990

Effects Of Artificial Mineral Licks On White-Tailed Deer., Stephen Redmore Schultz

LSU Historical Dissertations and Theses

A commercial mineral mixture for deer was used to evaluate the effects of broad-spectrum dietary mineral supplementation on white-tailed deer (Odocoileus virginianus) growth, antler development, and tissue mineral content. Forty-two artificial mineral licks for deer were established on 3 study areas in East Feliciana Parish, Louisiana. All licks were monitored monthly, recharged to original level if used, and mineral consumption recorded from May 1988 through December 1989. Consumption data were converted to estimated average per deer values based on population estimates. Effects of artificial lick mineral consumption on free-ranging deer were examined by comparing deer harvested during the 1988-89 and …


Predicting Pseudoneglect By Right Hemisphere Activation., Mark Sterling Warner Jan 1990

Predicting Pseudoneglect By Right Hemisphere Activation., Mark Sterling Warner

LSU Historical Dissertations and Theses

Hemispatial neglect is a visual-perceptual disorder characterized by a conscious and otherwise alert individual's failure to respond to a meaningful stimulus presented to the side opposite a right hemisphere brain lesion. In recent years researchers have demonstrated the existence of a neglect phenomenon in normal subjects which appears as the opposite of that experienced by brain injured subjects. This phenomenon is referred to as "pseudoneglect" and is demonstrated by horizontal line bisection to the left of true center. Researchers have suggested that pseudoneglect may be explained by preferential right hemisphere processing for visuospatial stimulation. The purpose of this study was …


Effects Of Food Plots On Selected Growth Parameters, Productivity, And Harvesting Of White-Tailed Deer In A National Forest., Kenneth Dale Dancak Jan 1990

Effects Of Food Plots On Selected Growth Parameters, Productivity, And Harvesting Of White-Tailed Deer In A National Forest., Kenneth Dale Dancak

LSU Historical Dissertations and Theses

A total of 8.1 ha of warm-season and 16.8 ha of cool-season food plots were installed on 2 of 4 study units at National Red Dirt Wildlife Management Preserve, Louisiana, an area managed by the USDA Forest Service for multiple resources. Mean ($\pm$ s.e.) study unit size was 2220 $\pm$ 246 ha. No food plots were installed on the remaining 2 study units (controls). Warm-season food plots were planted with American jointvetch (Aeschynomene americana); cool-season plots were planted with red clover (Trifolium pratense), subterranean clover (Trifolium subterraneum), winter wheat (Triticum aestivum) and white clover (Trifolium repens). All plots were maintained …


Panel Analysis: A Critical Method For Analyzing The Rhetoric Of Comic Book Form., Ralph Randolph Duncan Ii Jan 1990

Panel Analysis: A Critical Method For Analyzing The Rhetoric Of Comic Book Form., Ralph Randolph Duncan Ii

LSU Historical Dissertations and Theses

This study devises a method of rhetorical criticism, panel analysis, for the comic book medium. Panel analysis focuses on how the unique form of the comic book medium communicates content. Panel analysis consists of three components: historical context, micro analysis, and macro analysis. The historical component makes use of a humanistic historical approach to place a comic book or a body of comic book work in the contexts of the creator's personal history and the evolution of the comic book medium. These contexts provide understanding of the origins of the various formal aspects of the work(s) being studied. The micro …


Genotypic And Phenotypic Adaptations Of The Southern Oyster Drills, Stramonita Canaliculata And S. Haemastoma Floridana To Salinity., Li-Lian Liu Jan 1990

Genotypic And Phenotypic Adaptations Of The Southern Oyster Drills, Stramonita Canaliculata And S. Haemastoma Floridana To Salinity., Li-Lian Liu

LSU Historical Dissertations and Theses

Environmental and genetic effects on salinity adaptation in the southern oyster drill were estimated by their salinity-related genotypic (i.e. determined by electrophoresis) and phenotypic (i.e. determined by salinity tolerance and microcalorimetry) variations. The systematics of Stramonita haemastoma were studied using allozyme, radular and shell characteristics to exclude taxonomic differences which might have obscured variations in salinity adaptation. Radular and shell features are not reliable as systematic characteristics. S. h. canaliculata and S. h. floridana are separable using allozyme characteristics. Nei's genetic distance (D = 0.28) and the fixed allelic differences in Fum, LeuAla, Mdh, and 6-Pgdh indicate that the differences …


Existentialism And New England: The Poetry And Criticism Of Hayden Carruth., Anthony Jerome Robbins Jan 1990

Existentialism And New England: The Poetry And Criticism Of Hayden Carruth., Anthony Jerome Robbins

LSU Historical Dissertations and Theses

Hayden Carruth (b. 1921) has reached an advanced stage in his distinguished career as a poet, critic, and editor without having received the critical attention which he deserves and which has been accorded many of his less able contemporaries. He is a thorough-going existentialist, a dyed-in-the-wool Yankee, and an anarchist. The study uses these characteristics to explore the importance of his poetry and the nature of his complex relations with his chosen traditions. The first three chapters describe and analyze Carruth's development book by book from 1959 to 1983. The fourth chapter, "Carruth's Existential Revisions of Walden," considers Carruth's response …


A Comparative Study Of The Effects Of Sesbania Drummondii On The Hepatic Cytochrome P-450 Monooxygenase Systems Of Chickens And Rats., Marcy Iva Banton Jan 1990

A Comparative Study Of The Effects Of Sesbania Drummondii On The Hepatic Cytochrome P-450 Monooxygenase Systems Of Chickens And Rats., Marcy Iva Banton

LSU Historical Dissertations and Theses

The effect of an extract of Sesbania drummondii on the hepatic cytochrome P-450 monooxygenase system was evaluated in two experimental models, the White Leghorn chicken and the Sprague-Dawley rat. The cytochrome P-450 monooxygenase systems were compared using studies of catalytic activities and two major enzyme components, cytochrome P-450 and NADPH-cytochrome P-450 reductase. Two "classical" cytochrome P-450 inducers, phenobarbital and $\beta$-naphthoflavone, were used to probe induction mechanisms. S. drummondii induced opposite effects on the hepatic cytochrome P-450 component of chickens versus rats. Cytochrome P-450 specific content was increased 2-fold in chickens but decreased 2-fold in rats. Qualitative differences in microsomal proteins …


Isolation And Physical Mapping Of The Mitochondrial Chromosome From The Zygomycete Mucor Racemosus., Mary Louise Schramke Jan 1990

Isolation And Physical Mapping Of The Mitochondrial Chromosome From The Zygomycete Mucor Racemosus., Mary Louise Schramke

LSU Historical Dissertations and Theses

Mitochondria were isolated from Mucor racemosus and DNA was purified from these organelles by cesium chloride/ethidium bromide isopycnic centrifugation. Examination of mitochondrial DNA samples with a transmission electron microscope revealed a circular mitochondrial chromosome approximately 63.8 kbp in length. Summation of restriction fragments of mitochondrial DNA separated by agarose gel electrophoresis yielded a comparable value of 63.4 kbp for the size of the intact molecule. Electrophoretic mobility and stoichiometry were determined for restriction fragments generated using nine different restriction enzymes. A physical map was deduced from single and double digestions of mitochondrial DNA with several of the restriction enzymes. The …


The Narrative Creation Of Self In The Fiction By African-American And African-Caribbean Women Writers., Jerome P. De Romanet Jan 1990

The Narrative Creation Of Self In The Fiction By African-American And African-Caribbean Women Writers., Jerome P. De Romanet

LSU Historical Dissertations and Theses

This study entails an examination of the works of six authors (Maya Angelou, Audre Lorde, Paule Marshall, Toni Morrison, Gloria Naylor and Simone Schwarz-Bart) whose works are shaped by values and perceptions influenced by their experiences of sexual, racial and social marginalization. While I acknowledge differences in origin, beliefs and personality, I explore the common ground which unites them, and more specifically the complex ties that bind their individual "writing I" with their environment--"communitas," to use Victor Turner's term. This study is also an exploration of the modes in which these six writers create their idiosyncratic selves out of the …


The Development Of The Toddler Behavior Screening Inventory., Paula Yvette Mouton Jan 1990

The Development Of The Toddler Behavior Screening Inventory., Paula Yvette Mouton

LSU Historical Dissertations and Theses

The purpose of this study was to develop a Toddler Behavior Screening Inventory (TBSI) to rapidly assess maternal-perceived toddler behavior problems. The TBSI is a 40-item socially valid measure intended for use in clinical settings as it will aid child care professionals in planning parent-child intervention strategies. Empirical methods were followed to construct the TBSI. The item pool was generated primarily by 187 mothers with toddlers and relevant professionals. Items were reviewed and formatted before 312 mothers rated the initial 93-item TBSI in terms of behavior frequency and problem severity in order to eliminate items. Forty items were retained based …


Habitat Use, Movements, And Behavior Of Shiny Cowbirds In Southwestern Puerto Rico., Paul Michael Mckenzie Jan 1990

Habitat Use, Movements, And Behavior Of Shiny Cowbirds In Southwestern Puerto Rico., Paul Michael Mckenzie

LSU Historical Dissertations and Theses

Shiny Cowbirds were primarily located in six major areas of concentration. Of these, all but one was in mesquite woodland. Overall, cowbirds used mesquite woodland almost 75% of the time but use of this habitat varied among weekly periods and was linked to rainfall received during weekly periods prior to the observation. Habitat use of cowbirds and the time they spent eating particular prey items were most correlated with total rainfall received 2-5 weeks prior to the observation (p =.0067 and p =.0149, respectively). Major food items taken by cowbirds following periods of sufficient rainfall were caterpillars, berries and grass …

Biochemical Characterization And Gene Mapping Of The Channel Catfish Herpesvirus (Ccv)-Encoded Thymidine Kinase, A Selectable Site For Homologous Recombination., Larry Allen Hanson Jan 1990

Biochemical Characterization And Gene Mapping Of The Channel Catfish Herpesvirus (Ccv)-Encoded Thymidine Kinase, A Selectable Site For Homologous Recombination., Larry Allen Hanson

LSU Historical Dissertations and Theses

The channel catfish herpesvirus (CCV) encodes a thymidine kinase (Tk) which is biochemically distinguishable from it's host, the channel catfish ovary (CCO), and other herpesvirus Tk's. Tk deficient CCO cells (CCOBr) were developed by propagating CCO cells in increasing concentrations of 5-bromo-2$\sp\prime$-deoxyuridine (BUdR). CCV infection produced high Tk activity in these Tk deficient cells. This activity was compared to CCO-Tk in ATP and CTP phosphate donor assays, nucleoside substrate-competition and dTTP feedback inhibition assays. The viral Tk was more competitively inhibited by deoxypurines than cellular Tk and showed less dTTP mediated feedback inhibition. CCO-Tk utilized lower concentrations of ATP more …


Sampling And Analysis Of Dynamic Headspace Volatile Compounds From Selected Protein-Rich Food Matrices., Jose Ernesto Matiella Jan 1990

Sampling And Analysis Of Dynamic Headspace Volatile Compounds From Selected Protein-Rich Food Matrices., Jose Ernesto Matiella

LSU Historical Dissertations and Theses

Volatile compounds from two protein-rich foods, crabmeat and eggs, were studied with emphasis on qualitative and quantitative determination of a wide variety of chemical substances including degradation compounds from amino acids, lipids and carboyhdrates as well as compounds derived from the packaging material and the environment. Boiled and pasteurized blue crab (Callinectes sapidus) meat samples were analyzed for volatile flavor components by dynamic headspace sampling, capillary column gas chromatography and mass spectrometry. Fifty-three volatile compounds were identified in crabmeat samples. Levels of volatile compounds in both samples were compared and it was found that the boiled crabmeat contained higher levels …


The Use Of Cell Culture Systems To Improve Bovine Embryo Viability In Vitro., Stephen Harry Pool Jan 1990

The Use Of Cell Culture Systems To Improve Bovine Embryo Viability In Vitro., Stephen Harry Pool

LSU Historical Dissertations and Theses

Growth characteristics for fetal bovine uterine fibroblast cells (FBUFC) and frozen-thawed bovine (b) and caprine (g) trophoblastic vesicles (TV) were similar in (A) Ham's F-10 (HF-10), (B) MEM (with Earle's salts), (C) RPMI-1640 and (D) Menezo's B$\sb2$ (B$\sb2$), each supplemented with 10% FCS and Ab-Am (Experiment (Exp) I). Cell numbers declined initially but increased linearly thereafter for 5 days. The bTV and gTV that survived freezing had similar viability across time and Treatments (Trt). Exp II compared the (A) bTV, (B) FBUFC monolayer and (C) bTV-monolayer co-culture systems to (D) HF-10 alone for culture of 8- to 32-cell bovine embryos. …


Handel's English Oratorio Arias Based On Biblical Sources: An Annotated Catalogue. (Volumes I And Ii)., William Randall Richardson Jan 1990

Handel's English Oratorio Arias Based On Biblical Sources: An Annotated Catalogue. (Volumes I And Ii)., William Randall Richardson

LSU Historical Dissertations and Theses

The oratorios of George Frideric Handel (1685-1759) contain many outstanding arias. The typical aria is ordinarily diatonic and is a combination of symmetrical and asymmetrical phrase-lengths. Although sharing the same basic musical style, these arias are often quite different. Their ranges extend from the interval of a minor seventh to two octaves and sixty-six percent of them are set in forms other than da capo. In addition, the oratorio arias display a diversity of orchestration ranging from continuo arias to those that call for as many as eighteen different instruments. The main body of this paper is contained in chapters …
