The Effects Of Songs In The Foreign Language Classroom On Text Recall And Involuntary Mental Rehearsal, Claudia Smith Salcedo

LSU Doctoral Dissertations

This study investigated the effect of music on text recall and involuntary mental rehearsal (din) with students from four college-level Beginning Spanish classes. Two groups heard texts as songs, one group heard the same texts as speech, and one group was the control group. For the text recall variable, a cloze test was administered at the end of each song treatment to determine total words recalled. Students from one of the music groups heard the melody of the song while testing. For the din variable, students were asked to report on the amount of this phenomenon experienced. Data was collected …


Aspects Of Cognition In Human Mate Selection, Michael J. Stasio Jan 2002

Aspects Of Cognition In Human Mate Selection, Michael J. Stasio

LSU Doctoral Dissertations

Evolutionary perspectives on human mating have provided testable hypotheses regarding what qualities people desire in their mates and why they want them. One study was conducted to replicate previous findings in mate preference using a more sophisticated paired comparison methodology to develop scales. Paired comparison scaling generally replicated gender differences in mate preferences consistent with evolutionary predictions. Further, decision-making reaction time (ms) suggested the presence of an underlying psychological continuum of selection criteria. A series of studies were then conducted applying the information processing approach (IPA) to investigate attention and knowledge organization in mate preference. The dot-probe paradigm was used …


Wastewater Plume Dynamics And Bacteria Transport Within The Marshland Upwelling System, Stephen David Richardson Jan 2002

Wastewater Plume Dynamics And Bacteria Transport Within The Marshland Upwelling System, Stephen David Richardson

LSU Master's Theses

The marshland upwelling system (MUS) serves as an alternative onsite method for the treatment of domestic wastewater derived from coastal communities. Previous studies on the MUS have focused on the efficacy of the system for the removal of fecal pathogens from settled and secondarily-treated wastewater sources. The objectives of this research were to: 1) characterize the extent of wastewater migration within the MUS, 2) evaluate the effectiveness of the MUS in removing fecal bacteria, 3) identify the mechanisms responsible for fecal coliform retention within the subsurface, and 4) describe the transport of fecal coliforms in a sand media based on …

Taking Pr To School: A Case Study Of The Three Private High School Public Relations And Development Departments, Christine Cidalise Indest Jan 2002

Taking Pr To School: A Case Study Of The Three Private High School Public Relations And Development Departments, Christine Cidalise Indest

LSU Master's Theses

Few studies specifically explore public relations in private high schools. Statistics reveal that in Louisiana the number of nonpublic high school students continues to increase, therefore the competition among private schools for students increases as well as the demand to improve the private schools. These private schools need public relations to establish mutually beneficial relationships with strategic publics to attract students and to raise money to educate the students. This thesis is a case study of private school public relations programs at three Louisiana high schools. The theoretical basis for this thesis centered on the research of James Grunig. To …


Peroxynitrite-Mediated Oxidations: Nitration And Nitrosation, Rachel Bolzan Jan 2002

Peroxynitrite-Mediated Oxidations: Nitration And Nitrosation, Rachel Bolzan

LSU Doctoral Dissertations

Using a direct ultraviolet second-derivative spectroscopy method, three peroxynitrite preparative methods were investigated for the nitrite and nitrate present either as impurities or produced during peroxynitrite decomposition: (I) ozonation of azide, reaction of hydrogen peroxide with (II) isoamyl nitrite and (III) nitrous acid. The oxidation of morpholine by peroxynitrite in the presence and absence of added carbonate gives N-nitromorpholine and N-nitrosomorpholine. Nitration and nitrosation of morpholine are catalyzed by low levels of CO2; however, excess CO2 dramatically reduces the yields of nitrosation but not nitration, and the combined yields of the products are about the same under …


Development Of Low-Fat Sugar-Free Orange Sherbet Containing Soy Protein, Jonathan Aaron Walker Jan 2002

Development Of Low-Fat Sugar-Free Orange Sherbet Containing Soy Protein, Jonathan Aaron Walker

LSU Master's Theses

Consumer interest in healthy eating and self-medication is not just a passing fad. Soy-based products have become increasingly popular and gradually moved into the mainstream market. Many consumers associate soy with a healthy consumption pattern. Development of frozen desserts that indulge consumers’ eating desire, yet provide potential health benefits, is a challenge. Product appraisal to identify specific sensory attributes driving product acceptance is vital to the introduction of this new product. This thesis research was designed to develop low-fat sugar-free orange sherbet products containing soy protein and to determine the consumer sensory profile driving product acceptance and purchase intent. Two …


Feedback Seeking In Customer Service Relationships, Aletta Machell Barnard Jan 2002

Feedback Seeking In Customer Service Relationships, Aletta Machell Barnard

LSU Doctoral Dissertations

With the shift to a service economy (Cascio, 1995), customer service effectiveness is a critical measure of success for service firms. In service relationships, where a single employee may be the only point of contact for customers, monitoring service effectiveness becomes incumbent upon the employees delivering the service (i.e., boundary spanners). The purpose of this study was to provide an investigation into service effectiveness (i.e., customer satisfaction and repatronage and word-of-mouth intentions) in service relationships. Specifically, boundary spanners' perceived organizational support (POS) was proposed to impact customer satisfaction through its impact on feedback seeking behaviors (i.e., direct inquiry, monitoring, positive …

This research was Wave II of a longitudinal, qualitative study designed to describe the outcomes of welfare reform legislation on rural families in Louisiana as they tried to comply with provisions of the Personal Responsibility and Work Opportunity Reconciliation Act of 1996. This particular study looked at a subset of women (n=12) from Wave II and explored two questions: (a) Whether the decline in Louisiana welfare caseloads translated into rural women finding and keeping jobs; and (b) What is the likelihood that the women employed at the time of this study will be able to sustain their work efforts and …


Somatic Complaints And Health Care Utilization In Children Exposed To Violence, Kellie Ann Hilker Jan 2002

Somatic Complaints And Health Care Utilization In Children Exposed To Violence, Kellie Ann Hilker

LSU Doctoral Dissertations

In the United States, violence has been referred to as a public health epidemic and violence exposure of our youth is a particularly serious national concern. Numerous negative outcomes are associated with both child victimization and violence exposure including externalizing problems, internalizing symptoms, and poor academic performance. Somatic complaints, which have been associated with internalizing symptoms, have been found as well; however, physical complaints have not been studied in depth. Additionally, health care utilization is an area that is not widely studied in pediatric psychology, but positive associations between posttraumatic stress disorder and increased health care utilization has been found …

Factors Affecting The Selection Of Business Arrangements By Hog Producers In The United States, Christopher Gazzara Davis

LSU Doctoral Dissertations

The structure of the U.S. hog industry is changing rapidly. U.S. hog farms have become smaller in number, larger in size and more specialized. This study examines the factors that influence the hog producer's choice among business arrangements offered in the U.S. hog industry. A national survey was mailed to 4,986 hog producers to determine these factors. The survey consisted of questions covering topics such as: production characteristics, autonomy, transaction costs, risk, social relationships, and demographics. A response rate of 21% was received from the mailed surveys. Four alternative business arrangements were used: independent production, cooperative farming, flat-fee contract, and …


The Role Of Attention In Affect Perception: An Examination Of Mirsky's Four Factor Model Of Attention In Chronic Schizophrenia, Dennis R. Combs Jan 2002

The Role Of Attention In Affect Perception: An Examination Of Mirsky's Four Factor Model Of Attention In Chronic Schizophrenia, Dennis R. Combs

LSU Doctoral Dissertations

Attention and affect perception was examined in a sample of sixty-five persons with chronic schizophrenia. Attentional skills may be related to deficits in affect perception due to a lack of attention to important information contained in the face. Deficits of this sort can dramatically inhibit appropriate social functioning. However, there is a lack of empirical research on this topic. Mirsky's four factor model of attention was used as a broad-based assessment of attentional functioning. The four factors of attention were: 1) Focus-Execute, 2) Encode, 3) Sustain, and 4) Shift. Neuropsychological measures reflective of attentional factor were administered. In this study, …


Pleasure Principles: The Social Construction Of Gambling And Sex Addiction Treatment, M. Kelly James Jan 2002

Pleasure Principles: The Social Construction Of Gambling And Sex Addiction Treatment, M. Kelly James

LSU Doctoral Dissertations

The transformation of behavior into deviance requires many players, individuals, and institutions invested in the social construction process and its outcomes. Although considered private recreational matters by some, gambling and having sex are gaining spotlight in the addiction arena. With the growing availability of casino entertainment, lotteries, OTB venues, prostitution, internet pornography, and 900 numbers, gambling and sex are interpreted, labeled, and treated by addiction recovery specialists. Using ethnographic methods and face-to-face interviews, I explore a southern community’s institutions and practitioners providing services to gambling and sex addicts. I examine the community’s discourse and its methods for defining and controlling …


Treatment Acceptability For The Prevention Of Obesity And Type 2 Diabetes Mellitus: The Effects Of Ethnicity, Weight, And Genetic Predisposition, Jean Marie Thaw Jan 2002

Treatment Acceptability For The Prevention Of Obesity And Type 2 Diabetes Mellitus: The Effects Of Ethnicity, Weight, And Genetic Predisposition, Jean Marie Thaw

LSU Doctoral Dissertations

Childhood obesity and its associated health consequences, such as type 2 diabetes mellitus, have dramatically increased over the past 30 years, with the greatest rise in African-American female children and adolescents. Although current prevention efforts show promising results, recent genetic findings may soon expand treatment strategies to include new medications and gene therapies specifically designed to prevent the development of obesity and type 2 diabetes in children. However, little is known about the acceptability of these interventions. The primary aim of this study was to examine the hypothetical impact of genetic knowledge on treatment acceptability in the prevention of childhood …

Fecal Coliform Decay And Regrowth Kinetics In An Anaerobic Dairy Wastewater Environment, Shufang Liu

LSU Master's Theses

The kinetics of fecal coliforms (FC) decay and regrowth were analyzed under laboratory conditions using filtered dairy wastewater under anaerobic conditions. The mean specific growth rates during the regrowth phase, µr , in the batch study were 1.79, 1.46, and 1.27d-1 for initial organic carbon concentrations of 478, 235 and 127 mg/L COD, respectively. The substrate concentrations had a significant impact on the FC regrowth. A maximum specific growth rate (mmax) of 1.92 d-1, and half-saturated coefficient (ks) of 60.92mg/L were determined from these data. The mean dark FC decay rate coefficients, kd , at 35oC in the batch study …


Space And Organizations: The Ecology Of Rural Ngos In San Luis Potosi, Mexico, Patricia Marie Campion Jan 2002

Space And Organizations: The Ecology Of Rural Ngos In San Luis Potosi, Mexico, Patricia Marie Campion

LSU Doctoral Dissertations

The field of organizational ecology has been reduced to studies of population dynamics. Ecology, however, is a much broader field, that includes relational, spatial, and temporal dimensions. It allows us to combine existing theories of organizations to study their distribution across space. I combine insights from the new institutionalism, population ecology, and resource-dependence theory, to investigate the factors that influence the location of NGO activities in the state of San Luis Potosí­, Mexico. I conducted interviews and participant observation in 51 rural NGOs. The uneven distribution of NGOs in the state is not the result of their strategy to reach …


Development Of Diagnostic Tools For Detecting Expression Of Resistance-Associated Esterases In The Tobacco Budworm, Heliothis Virescens (F.), Huazhang Huang Jan 2002

Development Of Diagnostic Tools For Detecting Expression Of Resistance-Associated Esterases In The Tobacco Budworm, Heliothis Virescens (F.), Huazhang Huang

LSU Doctoral Dissertations

Esterase-based metabolic resistance was studied using biochemical and biological assays with organophosphate (OP)- and pyrethroid (PYR)- resistant tobacco budworms, Heliothis virescens. In biochemical assays, results suggest that: (1) esterase activities toward all substrates used were enhanced in both resistant strains compared with the susceptible strain, suggesting that esterases were involved in resistance; (2) esterase profiles differed depending on the strain and substrate used, and these differences were visualized by using native polyacrylamide gel electrophoresis; 3) esterase activities toward some pyrethroid substrates were significantly higher (P ≤ 0.01) in the PYR-R strain than those in the OP-R strain. These results suggest …


Critical Performative Pedagogy : Augusto Boal's Theatre Of The Oppressed In The English As A Second Language Classroom, Ross Mckeehen Louis Jan 2002

Critical Performative Pedagogy : Augusto Boal's Theatre Of The Oppressed In The English As A Second Language Classroom, Ross Mckeehen Louis

LSU Doctoral Dissertations

Performative pedagogy combines performance methods and theory with critical pedagogy in an effort to carry out the dual project of social critique and transformation. Performance offers an efficacious means of completing this project by privileging students’ historicized bodies, by implementing contingent classroom dialogue, and by exposing students to the value embedded in performance risk. In this study, I apply performative pedagogy to an English as a Second Language (ESL) context in response to its problematic pedagogical history. In particular, I argue that Augusto Boal’s Theatre of the Oppressed practice should be adapted as a method for doing performative ESL pedagogy. …


"Getting Above Your Raising" : The Role Of Social Class And Status In The Fiction Of Lee Smith, Sharon Elizabeth Colley Jan 2002

"Getting Above Your Raising" : The Role Of Social Class And Status In The Fiction Of Lee Smith, Sharon Elizabeth Colley

LSU Doctoral Dissertations

This dissertation examines the role of social class and status in the fiction of contemporary novelist and short story writer, Lee Smith. As discussed in the Introduction, the study defines social class broadly, not limiting it to production, but also not discarding its economic underpinning. Max Weber's definition of class as "life chances" provides the starting point; any resources that can improve a person's position in the market place positively impact their "life chances." The resources appearing most often in Smith's fiction include economic capital and property, as well as education, family connections and occupational status. The discussion also builds …

The experimental treatment involved four “Tips About Talk” parent-training workshops. The control …


Mexican Women And Migration: The Effects Of Education And Family Status, Veronica Cuartas Aravena Jan 2002

Mexican Women And Migration: The Effects Of Education And Family Status, Veronica Cuartas Aravena

LSU Master's Theses

Much existing research on migration of Mexican women has focused on those who migrate to the United States. However, most Mexican female migrants move within the country. This study asks two interrelated questions: (1) Does education, marital status, and the number of children influence Mexican women's migration status and (2) are there any differences in the way these factors affect internal versus international migration. Data from the Mexican Migration Project (2001) collected during the winter months of 1987-1997 (N=7610) are employed and three models are constructed, where non-migrants serve as the reference category. These models are also used to examine …

LSU Master's Theses

During January and February of 2002, a group of 15 marinas on the north shore of Lake Pontchartrain was surveyed to identify what environmental management practices they employed. The objectives of this study were to find out what was being done by these facilities in Louisiana, what these and other marina owners and operators could do to improve environmental conditions, and what recommendations could be made for future marina designers and operators. An additional objective was to suggest what role government could play in helping present and future marinas in implementing best management practices (BMPs). A questionnaire and evaluation form …


Screening And Characterization Of Pathogenic Fungi For Possible Control Of Coptotermes Formosanus, Jianzhong Sun Jan 2002

Screening And Characterization Of Pathogenic Fungi For Possible Control Of Coptotermes Formosanus, Jianzhong Sun

LSU Doctoral Dissertations

Coptotermes formosanus was used as “bait” to isolate pathogenic fungi from soil. Fifteen pathogenic fungal isolates were obtained, all either Metarhizium anisopliae (six isolates) or Beauveria bassiana (nine isolates). There were no differences in numbers of fungal isolates from the three sampling locations. However, significantly more isolates were found in woodlands (eleven) than in pastures (four). Median lethal doses (LD50s) of these fungal species to C. formosanus were interspersed, indicating that fungal isolates rather than species had the greatest effect on virulence. In vitro growth characteristics were significantly correlated with virulence against termites, suggesting that fungal virulence might be predicted …


The Effects Of Oryzanol On Bone Mineral Density In Ovariectomized, Retired Breeder Rats, Heather Compton Colona Jan 2002

The Effects Of Oryzanol On Bone Mineral Density In Ovariectomized, Retired Breeder Rats, Heather Compton Colona

LSU Master's Theses

The accelerated rate of bone loss that occurs after menopause may be reduced by consuming rice bran oil (RBO), which contains natural oryzanol. Three different forms of oryzanol (natural oryzanol, NO; crystalline oryzanol, CO; and solubilized oryzanol, SO) were evaluated in a rat model of postmenopausal women. Retired Sprague-Dawley breeder rats were stratified by weight and assigned randomly to one of five groups for a thirteen week study. Rats were either variectomized (O, n=37) or sham-operated (ShC, n=10) and assigned to control (C) diets (OC, n=10 or ShC, n=10) or one of three forms of oryzanol (NO, n=9; CO, n=9; …


Bacillus Anthracis Spore Concentrations At Various Carcass Sites, Pamala Rose Coker Jan 2002

Bacillus Anthracis Spore Concentrations At Various Carcass Sites, Pamala Rose Coker

LSU Doctoral Dissertations

Bacillus anthracis, the etiological agent of the disease anthrax, is a bacteria of great importance, both in the past and today. Despite this importance, many questions remain regarding defending against its use as a biological weapon, the bacteria's variation in virulence, and its epidemiology in nature. Using Etest strips (AB BIODISK, Solna, Sweden) to measure the MICs, 25 genetically diverse isolates of B. anthracis were tested to determine their susceptibility to seven clinically relevant antimicrobial agents. Using the NCCLS MIC breakpoints for staphylococci, three isolates were found to be resistant to penicillin and negative for beta-lactamase production. From a group …
