An Assessment Of Organizational Effectiveness: A Study Of West Virginia Watershed Associations., Sarah A. Cline

Graduate Theses, Dissertations, and Problem Reports (ETD)

Recently, federal and state government agencies have advocated a watershed approach to deal with water pollution issues. This approach addresses water quality and use on a watershed level and advocates public participation in watershed protection issues. In many communities, watershed associations have formed as an avenue for public involvement in a watershed approach. This thesis examines factors impacting watershed association effectiveness in reaching their intermediate goals (activities conducted and financial resources obtained for watershed protection) to achieve their final outcomes. Factors effecting the formation of watershed associations are also examined. Both analyses are conducted at the watershed level using the …

Expecting Women: Constructing The Pregnant Woman In Twentieth Century United States And British Dramatic Representation., Amelia Lynn Cuomo

LSU Historical Dissertations and Theses

Pregnancy and issues surrounding pregnancy such as paternity and legitimacy have been presented in Western Drama since its inception. Pregnancy in the modern era, however, has become a complex issue. Abortion, birth control, and the advent of new reproductive technologies (such as in vitro fertilization) alter understandings of reproduction. This study explores twentieth century British and U.S. dramatic representations of the pregnant woman and analyzes how pregnant women are constructed in drama. The dissertation is divided into five chapters. Chapter One explores four plays by male playwrights: Harley Granville Barker's Waste, Eugene O'Neill's "Abortion," and Sidney Kingsley's Men in White …

The Values-Ethical Dimension: Do Bsw Students In State-Supported And Religiously Affiliated Programs Differ?, Wade Milton Tyler

LSU Historical Dissertations and Theses

Although an important aspect of any baccalaureate social work program is the inculcation of social work values, there has not been an abundance of studies in this area. Many of those that exist have been criticized for their methodology in measuring values. It is appropriate to examine that which has been termed the "fulcrum" of social work practice relative to the educational processes which purport to put that fulcrum in place. The purpose of this study was to compare BSW students in religiously-affiliated institutions of higher education with those in state-supported institutions on three dimensions: adherence to social work values, …

On Biodata Construct Validity, Criterion-Related Validity, And Adverse Impact., Michelle Ann Dean

LSU Historical Dissertations and Theses

This study examined the personnel selection technique of biographical information (biodata) in terms of theory, criterion-related validity, and adverse impact. First, the construct validity of biodata was examined to determine if biodata theory was useful in explaining biodata's strong criterion validity. Items from an existing biodata inventory were mapped onto construct domains drawn from Mumford, Stokes, and Owens' (1990) ecology model. Relationships between subjects' biodata responses and training performance was examined for consistency with the model's predictions in an organizational sample. The ecology model did not fit the data well. Follow up exploratory analyses did yield good fit when the …

Ernest Renan And The Question Of Race., Jane Victoria Dagon

LSU Historical Dissertations and Theses

Racism in France can be traced back to the 1560's when the nobles claimed to be of a separate race in order to obtain special rights and privileges. Soon after in the seventeenth century, scientists started to classify humans according to physical features. With the increase in travel, the slave trade, the fear of the unknown and the fear of contamination, these factors along with physiognomy and phrenology encouraged "biological racism." During the second half of the nineteenth century, Ernest Renan (1823--1892) denounces biological racism and the existence of the so-called "pure races." He is also the first dramatist to …

Effects Of Low-Oxygen Atmosphere On The Growth And Development Of Arabidopsis Thaliana (L.) Heynh., Katrina Maria Ramonell

LSU Historical Dissertations and Theses

Interest in the improvement of crop productivity through repression of photorespiration led to experimental growth of plants in low O2 and the surprising finding that reproduction is inhibited under these conditions. Using Arabidopsis thaliana (L.) Heynh. cv. Columbia, studies were undertaken to understand the mechanism behind oxygen control of plant development. The hypothesis that developmental changes observed in low O 2 are due to repression of the plant hormones ethylene and brassinolide (which require O2 for biosynthesis) was tested. Arabidopsis was grown for 35 days in Sun bags in one of five altered O 2 atmospheres (210, 160, 100, 50, …

Parameter Estimation For The Finite Fourier Distribution In Civil Engineering Application., Ching-Nien Tsai

LSU Historical Dissertations and Theses

A solution to a one dimensional diffusion equation applicable to a finite interval was adapted to be a probability distribution function. This distribution function can accommodate various shapes of distribution such as those similar to the uniform, single-modal, and bi-modal distributions. This distribution is bounded at both boundaries. It was named the finite Fourier distribution (FFD) to recognize the form of the distribution. The FFD was extended to include a linear combination of the FFD termed two-component FFD. Monte Carlo simulation technique was used to evaluate four parameter estimation techniques, Method of Maximum Likelihood Estimator (MLE), Method of Moments (MOM), …

Intervention Implementation And Intervention Outcomes For Teenage Mothers In School -Based Treatment For Social And Academic Problems., Cherri Edenfield Penton

LSU Historical Dissertations and Theses

The effects of a strong treatment package, comprised of 2 types of performance feedback plus incentives, on the social behavior and academic progress of 9 minority teenage mothers attending an inner-city high school, was investigated. Treatment integrity of their teachers and parents was also evaluated. Research shows that academic deficits and conduct problems are strong correlates of early pregnancy, Many students experience academic failure and related disciplinary problems because no one monitors their behavior. In this study, a comprehensive treatment was developed to be used across settings (home, school and a school-based health clinic) and across treatment agents (parent, teacher, …

Evaluation And Heritability Of Resistance To Sugarcane Red Rot And The Effects Of Environmental Stress On Disease Severity., Zhi Yin

LSU Historical Dissertations and Theses

Heritability of resistance to red rot, caused by Colletotrichum falcatum, was studied using progeny from 40 crosses among 24 parental clones of sugarcane. Significant differences in susceptibility were detected, although high levels of resistance were rare in the breeding and selection populations of the Louisiana sugarcane cultivar development program. Narrow-sense heritability estimates determined by mid-parent-offspring regression for four different disease traits ranged from 0.19 +/- 0.04 to 0.31 +/- 0.05. Potential genetic gain by selection for resistance, using a 10% selection intensity, ranged from 14 to 37% of the mean. The rot index provided the highest heritability estimate and the …

Ideomotor Apraxia And Lesion Location: Analysis Of Error Types, Motor Function, And Task Demands., Brenda Hanna-Pladdy

LSU Historical Dissertations and Theses

Ideomotor apraxia is a disorder of learned skilled movement which typically has been attributed to damage confined predominantly to the frontal and parietal cortical areas within the hemisphere dominant for speech. However, most studies of the anatomical basis of apraxia have relied on case studies or have only approximate lesion localization, and few studies have examined motor performance in relation to lesion location. This study examined the relationship of apraxia severity to lesion location (in both cortical/subcortical dimensions and anterior/posterior dimensions), aphasia, motor performance, and task demands, and identified the existence of subtypes of apraxia with characteristic performance profiles (error …

Characterization Of The Microsomal Mixed -Function Oxidase System Of Several Species Of Sea Anemones (Phylum: Cnidaria)., Linda Marie Heffernan

LSU Historical Dissertations and Theses

Several studies have demonstrated detrimental effects of anthropogenic compounds on coral reef communities. These compounds are known to be bioaccumulated rapidly, but eliminated slowly by anthozoans (i.e., corals and sea anemones). The cytochrome P450-dependent mixed function oxidase (MFO) system is the primary pathway for initial oxidation of many hydrophobic exogenous compounds; however, its presence had not been well documented in anthozoans. The studies reported herein show that a functional cytochrome P450-dependent MFO is present in the microsomal fraction of the sea anemones Anthopleura xanthogrammica , A. elegantissima, and Bunodosoma cavernata . The evidence is based on the presence of classical …

Land -Cover Change Detection For The Tropics Using Remote Sensing And Geographic Information Systems., Jane M. Read

LSU Historical Dissertations and Theses

Changing land-cover in the tropics is a central issue in global change research. This dissertation used Landsat-TM data to examine processes of land-use and land-cover changes for a lowland tropical site in Sarapiqui, Costa Rica. Performances of selected image-processing methods to detect and identify land-cover changes were evaluated. A land-cover time-series from 1960 to 1996 for the site was generated using maps derived from aerial photographs and Landsat-TM classifications. Changes in land-cover from 1986 to 1996 were evaluated using standard landscape indices, and interpreted in terms of their historical context. Dominant changes in the site during this decade included the …

Systematics Of The Common Garter Snake, Thamnophis Sirtalis., John Jeffrey Boundy

LSU Historical Dissertations and Theses

Character variation was examined in the snake Thamnophis sirtalis . Initially, 187 characters were examined on five populations (OTUs). Only 12% of the characters failed to show geographic variation by ANOVA. A reduced data set of 72 characters remained after eliminating those that were invariant and correlated. The reduced data set was analyzed for interpopulation variation between 37 OTUs, of T. sirtalis. Numbers of significantly differentiated characters between OTUs, determined by ANOVA, were used to generate a UPGMA tree. The tree placed Texas and Chihuahuan populations as sister groups to all other OTUs, and grouped OTUs from west of the …

Reawakening Sleeping Beauty: Fairy -Tale Revision And The Mid -Victorian Metaphysical Crisis., Cynthia Lynn Demarcus

LSU Historical Dissertations and Theses

Despite growing scholarly recognition of subversive social and political content in Victorian fairy tales, their significance in relation to the oft-cited Victorian "spiritual crisis" remains largely unexplored. This interdisciplinary study addresses that critical gap by examining three literary revisions of Sleeping Beauty from the early 1860s as pointed efforts to enter the intensified religious debate following the publication of Charles Darwin's Origin of the Species. The three revisions---Charles Dickens's novel Great Expectations (1860--61), Christina Rossetti's narrative poem "Goblin Market" (1862) and George MacDonald's fairy-tale "The Light Princess" (1864)---all appropriate the popular Sleeping Beauty narrative to create a vivid and emotionally …

Flexural Creep Analysis Of Recycled Polymeric Structural Elements., Jose Noe Martinez-Guerrero

LSU Historical Dissertations and Theses

A structural product made of recycled plastics in standard sections similar to dimensional lumber is referred to as plastic lumber. The recycled plastics used in the manufacture of these members include high density polyethylene, polyethylene terephthalate and polystyrene. Plastic lumber is a viscoelastic material possessing mechanical properties that are time and temperature dependent. This structural product is currently used primarily in non-load-bearing and low-end structural applications because of the non availability of engineering data and concerns about its creep behavior. Creep, which is the time dependent deformation under constant stress, is high for plastic lumber and is temperature sensitive. A …

Parental Alcoholism And Children's Social Skills., Marsha Dean Norton

LSU Historical Dissertations and Theses

This study focused on the daily interactions and home environments of 14 families with alcoholic fathers who were beginning primary treatment for their alcoholism. Data were collected by in-depth, face to face interviews with all family members. Social skills questionnaires administered to each child. Two specific family patterns were found to be associated with higher level social skills in children. First, father's frequent presence in the home, coupled with positive family interaction, was associated with children's high range social skills. Even in circumstances where violence existed, if the father was routinely at home and participated in positive family interactions, social …

Reduction Of Endogenous Bacteria Associated With Catfish (Ictalurus Punctatus) Fillets Using The Grovac Process., Milton Ruben Ramos

LSU Historical Dissertations and Theses

Fresh catfish (Ictalurus punctatus) fillets (CF) can serve as vehicles for spoilage and pathogenic bacteria. Concern for the microbiological safety of chilled CF has grown lately because psychrotrophic pathogens can survive and grow at refrigeration temperatures. The Grovac method, a new, patented (U.S. 5,543,163) process is being used in an attempt to reduce the growth of pathogens and spoilage microorganisms in CF. This process involves the using of a process solution of ascorbic acid (AA) and sodium chloride (NaCl), vacuum and tumbling. Specific objectives of this study included the isolation and identification of endogenous microflora associated with fresh whole catfish …

Synthesis, Thermodynamic Stability And Enzymic Behavior Of Oligonucleotides Containing Pyrazole Nucleobase Analogs., Andrea Sapp Saurage

LSU Historical Dissertations and Theses

Non-hydrogen bonding nucleosides with iodo, nitro, propynyl and thiazolyl substituted at the 4-position of pyrazole were prepared. These nucleosides were converted to their corresponding nucleoside phosphoramidites and incorporated into a series of complementary oligonucleotides in order to determine the effect that varying size, charge distribution and polarizability has on duplex stability and structure. The self-complementary Dickerson dodecamer sequence 5'-CGCXAATTYGCG-3', as well as the non-self complementary sequence 5'-CAAAATGGTGGCCAAGT-3 ' previously investigated by Brown, were used to determine the duplex stabilization and thermodynamic consequences of placing 5-nitroindole and 4-substituted pyrazole nucleosides across from each natural base. In the pyrazole series, the largest …

Sire Selection And Mating Practices In United States Dairy Herd Improvement Association Holstein Herds., Asiye Yilmaz

LSU Historical Dissertations and Theses

Over two million Holstein mating records was used to investigate selection and mating practices. Population statistics revealed non-random mating and selection. Herd production level was associated with higher breeding value sires and price paid per unit of semen. The decision to use an Artificial Insemination (AI) sire or natural service sire was studied and a discriminant function was derived that accurately categorized matings in a test data set of 117,000 observations, with an error rate less than 2.5 percent. Discriminating variables were herd production level, lactation number, service number, breeding month, cow status code, and days in milk at breeding. …

How The Villanelle's Form Got Fixed., Julie Ellen Kane

LSU Historical Dissertations and Theses

This work debunks the myth of the villanelle as a "fixed poetic form" dating back to the sixteenth century or earlier and replaces it with a new-historical account of how a semi-improvisatory musico-poetic genre, the choral-dance lyric, was "translated" across ruptures in lyric technology between oral, manuscript, and print cultures. The "fixity" of the villanelle's written form is shown to be not a matter of long-standing "heritage" or "tradition," but the result of deliberate actions taken by one eighteenth- and one nineteenth-century individual who inserted less-than-truthful passages into otherwise "authoritative" prosodic treatises. Chapter 1 identifies the literary sources responsible for …
