Optimization And Automation Of A Thermal Oyster Shucking Process, Daniel Edgar Martin Jan 2003

Optimization And Automation Of A Thermal Oyster Shucking Process, Daniel Edgar Martin

LSU Doctoral Dissertations

Louisiana Gulf Coast oysters (Crassostrea virginica) were subjected to thermal shucking treatments to effect adductor muscle release from both left and right valves. The oysters were instrumented with thermocouples to monitor and record process temperatures in the oysters and on the shell. Following treatment, the oysters were evaluated for relaxation and release of the adductor muscle, meat quality and texture, and for the effect of the treatments on the storage life of the oysters as measured by total microbial plate counts. The treatments of many oysters resulted in a complete release of the adductor muscle from the shell while maintaining …

Collective Efficacy: A Framework For Understanding Classroom Teacher's Perceptions Of Integrating Physical Activity, Melissa Ann Park Jan 2003

Collective Efficacy: A Framework For Understanding Classroom Teacher's Perceptions Of Integrating Physical Activity, Melissa Ann Park

LSU Doctoral Dissertations

Children’s physical inactivity is becoming an important health concern, and it has been suggested by professionals that school programs can be important in the effort to increase activity levels. Physical education specialists cannot achieve the goal of significantly increasing children’s activity in isolation, and it is apparent that whole school programs at the elementary level have the potential to foster active lifestyles. If those programs are to be successful, all school personnel must play a role, so it is important to find ways to facilitate their involvement. The purpose of this study was to use collective efficacy as a framework …

Adherence To Medical Regimens In Low-Income Adults With Type 2 Diabetes: The Influence Of Perceived Control Constructs, Erin L. O'Hea Jan 2003

Adherence To Medical Regimens In Low-Income Adults With Type 2 Diabetes: The Influence Of Perceived Control Constructs, Erin L. O'Hea

LSU Doctoral Dissertations

Individuals with Type 2 diabetes often do not adhere to their treatment regimens (e.g., exercise, diet, medication, glucose monitoring). Non-adherence results in poor metabolic control, further morbidity and mortality, and increased health care utilization and costs. One common thread among many health-behavior-theories that attempt to explain non-adherence behaviors is the importance of perceived control. This psychosocial variable has most often been conceptualized as ‘health locus of control,’ which refers to the belief that one has the ability to influence or change one’s health outcomes. Inconsistent findings have been reported regarding the relationship of health locus of control and medical regimen …

Physical Function And Quality Of Life In The Very- And Oldest-Old: Gender Differences, Kellye A. Ferachi Jan 2003

Physical Function And Quality Of Life In The Very- And Oldest-Old: Gender Differences, Kellye A. Ferachi

LSU Master's Theses

Age is associated with deterioration in physical function (PF) and health-related quality of life (HRQL). Recent investigations suggest that a decrease in function may have a greater impact on perceived activities of daily living (ADL) competency in women than in men. The purpose of this investigation was to test the hypothesis that the association between PF and HRQL among older adults is influenced by gender. We examined 108 older adults aged 60 years or older, for PF (Continuous Scale-Physical Function Performance test (CS-PFP10) and Functional Status Index (FSI)) and HRQL (SF-36). In order to address this question we assigned subjects …

Barriers To Adherence In A Free Medication Program For Low Income Individual With Type 2 Diabetes, Bhrett A. Mccabe Jan 2003

Barriers To Adherence In A Free Medication Program For Low Income Individual With Type 2 Diabetes, Bhrett A. Mccabe

LSU Doctoral Dissertations

Diabetes self-management and treatment require significant patient involvement to maintain appropriate glucose control. Glucose control is directly related to adherence to a variety of regimens, of which medication adherence may be most important. Unfortunately, adherence to these regimens has been quite poor. Among low income patients, the strongest reason given for medication nonadherence has been the cost associated with purchasing medication. In 1999, the Louisiana State University Health Care Services Division instituted a free medication program for low income individuals with chronic illnesses, including diabetes. Despite removing this strongest barrier to adherence among low income patients, initial data from this …

Use Of Primary Production By Benthic Invertebrates In A Louisiana Salt-Marsh Food Web, Padma Maddi Jan 2003

Use Of Primary Production By Benthic Invertebrates In A Louisiana Salt-Marsh Food Web, Padma Maddi

LSU Master's Theses

A combination of natural abundances of stable carbon and nitrogen isotopes and tracer-addition experiments were employed to determine the relative contributions of three potential food sources (phytoplankton, benthic microalgae, and Spartina alterniflora) to benthic invertebrate fauna of Louisiana salt marshes. Samples of the major food sources and the consumers were collected quarterly (summer, fall, winter and spring) to analyze the ƒÔ13C and ƒÔ15N ratios. A simultaneous tracer-addition experiment, in which benthic microalgae (BMA) were labeled with NaH13CO3 and 15NH4Cl, was conducted in all quarters to determine the relative importance of the BMA to consumers. Results indicated that the carbon isotopic …

Numerical Solution Of Ocular Fluid Dynamics, Satish Kumar Jan 2003

Numerical Solution Of Ocular Fluid Dynamics, Satish Kumar

LSU Master's Theses

Numerical calculations of the aqueous humor dynamics in the anterior chamber of both the rabbit and the human eye are presented to delineate the basic flow and transport mechanisms. The calculations are based on a geometrical model of the eye, which represents the Trabecular mesh (TM) as a multi-layered porous zone of specified pore sizes and void fraction. Buoyancy is observed to be the dominant driving mechanism for the convective motion in both orientations (horizontal and vertical) of the eye. Reducing the TM pore size does not appear to have a significant influence on the intra-ocular pressure (IOP) until the …

Metabolic Aspects Of Oryzanol In Rats, Michelle Smith Gillespie Jan 2003

Metabolic Aspects Of Oryzanol In Rats, Michelle Smith Gillespie

LSU Master's Theses

Using a rat model, this study compared the bioavailability of three forms of oryzanol, a compound extracted from rice bran oil that has been associated with improved cholesterol levels. Various methods of extracting lipids from serum and liver were explored to determine oryzanol absorption. Cholesterol levels were obtained via enzymatic colorimetric assay and GCMS. Sprague Dawley retired female breeder rats were sustained for 11 weeks on a cholesterol-free diet to which either no oryzanol was added (n = 19) or 2.8 g/kg of oryzanol was added as: 7% oryzanol rice bran oil (RO, n = 8), crystalline oryzanol (CO, n …

The Relationship Between Depression And Feeding Disorder Symptoms Among Persons With Severe And Profound Mental Retardation, Stephen Bradley Mayville Jan 2003

The Relationship Between Depression And Feeding Disorder Symptoms Among Persons With Severe And Profound Mental Retardation, Stephen Bradley Mayville

LSU Doctoral Dissertations

In recent years, feeding disorders have been described in detail, and various assessment and treatment methods for these disorders have been reported. Within the literature, an emphasis has been placed on functional variables responsible for the onset and maintenance of feeding disorders, yet little has been reported on the relationship between feeding disorders and other forms of psychopathology. Therefore, the relationship between depression and feeding disorders was assessed. Three groups of individuals were compared across subscales and individual items on the Screening Tool for Feeding Problems (STEP) to assess for differences in problematic feeding behavior. Individuals who met diagnostic criteria …

An Anthropological Examination Of Classic Maya Burials From Moho Cay, Belize: Skeletal And Dental Evidence Of Demography, Diet And Health, Erin Suzanne Lund Jan 2003

An Anthropological Examination Of Classic Maya Burials From Moho Cay, Belize: Skeletal And Dental Evidence Of Demography, Diet And Health, Erin Suzanne Lund

LSU Master's Theses

In the Maya area, archaeological excavations have yielded an abundance of skeletal material from a multitude of sites throughout Belize, Guatemala, Mexico, El Salvador and Honduras. In 1979, a series of excavations led by Heather McKillop at Moho Cay, Belize, revealed a number of human interments. This thesis analyzes the Moho Cay skeletal collection composed of remains from eight discrete Late Classic (A.D. 600-800) burials and nine other archaeological units. Skeletal and dental analysis of the remains included assessing minimum number of individuals per burial and establishing age and sex for each individual. The bones were also examined for signs …

Psychosocial Predictors Of Dietary Fat Reduction: The Role Of Stress And The Transtheroetical Model In A Dietary Intervention, Jennifer L. Francis Jan 2003

Psychosocial Predictors Of Dietary Fat Reduction: The Role Of Stress And The Transtheroetical Model In A Dietary Intervention, Jennifer L. Francis

LSU Doctoral Dissertations

Dietary fat is related to cardiovascular disease and numerous intensive, controlled clinical trials have successfully reduced dietary fat in symptomatic populations. However, there has been less success in large, community-based studies with healthy or mildly at-risk populations. Little is known about predictors associated with actual change in dietary fat intake and this is an important omission because dietary interventions are more likely to be successful if they are based on factors known to influence behavior. The purpose of this study was to investigate the psychosocial predictors of dietary fat and dietary fat reduction through the framework of the transtheoretical model …

Do Not Resuscitate Decision-Making: Ohio's Do Not Resuscitate Law Should Be Amended To Include A Mature Minor's Right To Initiate A Dnr Order, Allison Mantz Jan 2003

Do Not Resuscitate Decision-Making: Ohio's Do Not Resuscitate Law Should Be Amended To Include A Mature Minor's Right To Initiate A Dnr Order, Allison Mantz

Journal of Law and Health

Part One discusses Ohio's current DNR (Do Not Resuscitate) law, which does not include an exception for mature minors. It explains the medical difference between initiating a valid DNR order and refusing life-sustaining medical treatment. However, the note solely focuses on DNR and how it relates to a minor's right to initiate his or her own DNR order in light of parental disagreement. Part two explains the evolution of the minor and healthcare. Specifically, the progression from the early common law assumption that minors lack the capacity to consent, to the present, in which minors are permitted to make some …

Use Of Irradiated And Formalin-Fixed Trichomonas Vaginalis To Examine Protective Immune Responses In The Mouse Intraperitoneal Model, Terryl L. Hostetler, James J. Daly, Timothy J. O'Brien, Max L. Baker Jan 2003

Use Of Irradiated And Formalin-Fixed Trichomonas Vaginalis To Examine Protective Immune Responses In The Mouse Intraperitoneal Model, Terryl L. Hostetler, James J. Daly, Timothy J. O'Brien, Max L. Baker

Journal of the Arkansas Academy of Science

Gamma irradiated Trichomonas vaginalis was used to initiate a protective immune response in mice by intraperitoneal inoculation using host mortality as the measure of virulence. Irradiated trichomonads of a virulent strain gave some immune protection but no more so than the use of formalin-fixed, virulent trichomonads. A formalin-fixed virulent strain combined with complete Freund's adjuvant (CFA) gave complete protection. Metabolically produced antigens do not appear to be important in conferring protective immunity in these experiments. A common laboratory strain of T. vaginalis (ATCC 30001) was used as an avirulent control. It gave no protection against a virulent strain. Combining CFA …

Effect Of Water Removal On Introduced Caddisflies From A Tropical Mountain Stream, Mollie D. Mcintosh, Mark Eric Benbow, Albert J. Burky Jan 2003

Effect Of Water Removal On Introduced Caddisflies From A Tropical Mountain Stream, Mollie D. Mcintosh, Mark Eric Benbow, Albert J. Burky

Biology Faculty Publications

Tropical island streams worldwide are being threatened by existing or proposed dams and diversions. Numerous streams of the Hawaiian Islands have diversions that remove freshwater for human use; however, little research has addressed diversion effects on aquatic insect communities in tropical streams. We studied the effect of water removal by a stream diversion on density and biomass of two introduced Trichoptera, Cheumatopsyche analis (Banks) (Hydropsychidae) and Hydroptila potosina (Buenoa- Soria) (Hydroptilidae), in Iao Stream, Maui, Hawaii, from April-August 2000. Both species seem to have multivoltine life cycles. Pooled Trichoptera (both species) biomass was significantly greater above the diversion (178.3 mg.m-2 …

Prediction Of Treatment Dropouts From Outpatient Substance Abuse Rehabilitation: A Discriminant Analysis., Phyllis J. Harner-Neer Jan 2003

Prediction Of Treatment Dropouts From Outpatient Substance Abuse Rehabilitation: A Discriminant Analysis., Phyllis J. Harner-Neer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Significant research literature supports the need for programs better designed to meet the needs of adolescent substance treatment. There is little research, however, that addresses the identification of characteristics of those adolescents who do not complete treatment. Consequently, this study seeks to identify those characteristics of adolescents by segueing off of another study that proved successful in identifying characteristics among inpatient adult male substance abusers. This study looks at the archival data of 38 adolescents who attended outpatient substance abuse treatment at an experientially-based, substance abuse program designed for adolescents. Methodological processes included the use of demographic variables collected through …

Big Boys Don't Cry : Understanding Barriers To Seeking Support For Mental Health Problems Among Adolescent Males, Amanda Miraudo Jan 2003

Big Boys Don't Cry : Understanding Barriers To Seeking Support For Mental Health Problems Among Adolescent Males, Amanda Miraudo

Theses: Doctorates and Masters

This study explored the possible barriers encountered by adolescents in developing and achieving positive mental health. Male adolescents in Perth, Western Australia were consulted in an attempt to provide insight into the motivating and inhibiting factors influencing help-seeking as a coping strategy. Barriers to seeking help for mental health problems were investigated through the inductive process of grounded theory (Glaser & Strauss, 1967) to obtain a more detailed understanding of help-seeking than previous studies have provided; The study found that the coping responses most frequently enacted by the adolescent males sampled included avoidance, diversion, and private resolution. Help-seeking was far …
