An Examination Of Psychotropic Medication Prescription Practices Among Individuals With Mental Retardation, Ashvind Nand Singh Jan 2005

An Examination Of Psychotropic Medication Prescription Practices Among Individuals With Mental Retardation, Ashvind Nand Singh

LSU Master's Theses

While there is an extensive literature on the use of psychotropic medications among individuals with mental retardation, little of it has focused on the reasons for these prescriptions. Researchers have shown that the prevalence of psychotropic medication use among individuals with mental retardation is relatively high when compared to people with other disabilities and that the reasons for these drug prescriptions may not be based on rational pharmacotherapy. Data is needed on the prescribing physician’s adherence to consensus guidelines or algorithms developed to enhance rational psychopharmacotherapy. In order to do this, the rationales being used by physicians when they decide …

Antimicrobial Effect Of Cetylpyridinium Chloride Against Listeria Monocytogenes Growth On The Surface Of Raw And Cooked Shrimp, Tracie Michelle Dupard Jan 2005

Antimicrobial Effect Of Cetylpyridinium Chloride Against Listeria Monocytogenes Growth On The Surface Of Raw And Cooked Shrimp, Tracie Michelle Dupard

LSU Master's Theses

Listeria monocytogenes has emerged as a major foodborne pathogen for the seafood industry due to its psychrotrophic nature and its ubiquitous presence. It has been isolated from soil, sewage, dead vegetative matter, aquatic environments, fecal material, fish, crustaceans, and domesticated animals. As a result, L. monocytogenes has been responsible for several shrimp recalls and has been epidemiologically linked to human listeriosis. Fresh seafood products are highly perishable and their shelf-life is limited by microbiological spoilage. Therefore, when pathogenic microorganisms are involved, it poses a health threat to the general public. The situation is further complicated because seafood processing plants are …

Black Catholicism: Religion And Slavery In Antebellum Louisiana, Lori Renee Pastor Jan 2005

Black Catholicism: Religion And Slavery In Antebellum Louisiana, Lori Renee Pastor

LSU Master's Theses

The practice of Catholicism extended across racial boundaries in colonial Louisiana, and interracial worship continued to characterize the religious experience of Catholics throughout the antebellum period. French and Spanish missionaries baptized natives, settlers, and slaves, and the Catholic Church required Catholic planters to baptize and catechize their slaves. Most slaveholders outside New Orleans, however, were lax in the religious education of slaves. Work holidays did not always correspond to religious holy days, and the number of slave baptisms and confirmations on Catholic plantations often depended on the willingness of the local priest, or the slaves themselves, to attend the parish …

Semantic Classification Of Rural And Urban Images Using Learning Vector Quantization, Prakash Thulasiraman Jan 2005

Semantic Classification Of Rural And Urban Images Using Learning Vector Quantization, Prakash Thulasiraman

LSU Master's Theses

One of the major hurdles in semantic image classification is that only low-level features can be reliably extracted from images as opposed to higher level features (objects present in the scene and their inter-relationships). The main challenge lies in grouping images into semantically meaningful categories based on the available low-level visual features of the images. It is important that we have a classification method that will handle a complex image dataset with not so well defined boundaries between clusters. Learning Vector Quantization (LVQ) neural networks offer a great deal of robustness in clustering complex datasets. This study presents a semantic …

Environmental Benefits Realized From Eradication Of The Non-Indigenous Insect Anthonomus Grandis Boheman, The Cotton Boll Weevil, Marc Stephen Bordelon Jan 2005

Environmental Benefits Realized From Eradication Of The Non-Indigenous Insect Anthonomus Grandis Boheman, The Cotton Boll Weevil, Marc Stephen Bordelon

LSU Master's Theses

At least one third of the insecticide used in agriculture has been used to control the boll weevil in cotton. Historically, these insecticides have been toxic to humans and harsh on the environment. In addition, the intensive use of chemical insecticides to control the boll weevil results in the disruption of naturally occurring biological control factors that regulate other insect pest populations causing a chain reaction of secondary pest populations that require treatment followed by resurgence and repeat treatment. This situation has resulted in the development of resistance to insecticides, high control costs and unacceptable levels of chemical insecticide contamination …

The 17 Kda Protein In Photosystem Ii, Purification And Interaction With The Photosystem, Glen Meades Jan 2005

The 17 Kda Protein In Photosystem Ii, Purification And Interaction With The Photosystem, Glen Meades

LSU Master's Theses

The structural association of the spinach 17 kDa protein of photosystem II with other extrinsic and membrane-bound components of the photosystem was investigated by labeling the 17 kDa protein with the amino group-specific reagent N-hydrosuccinimidobiotin both on intact photosystem II membranes and free in solution. Following isolation of the biotinylated molecules, the modified 17 kDa protein was allowed to rebind at various molar ratios to photosystem II membranes lacking the 17 kDa protein. Differential binding of the biotinylated proteins compared to unmodified 17 kDa protein indicates steric or ionic interference due to added biotin moieties, impeding physical contact or shielding …

A Bioeconomic Supply Model For Louisiana Nutria And Impacts On Wetlands Conservation Associated With Economic Incentives, Cheikhna Ould Dedah Jan 2005

A Bioeconomic Supply Model For Louisiana Nutria And Impacts On Wetlands Conservation Associated With Economic Incentives, Cheikhna Ould Dedah

LSU Master's Theses

Nutria (Mayocastor) were first introduced to Louisiana in 1938. With few natural predators and high prolific productivity, they became well established in the surrounding coastal marsh within a few years. Prior to 1980’s, as a result of high demand for nutria products from European countries, harvest pressure was sufficient to keep the population in ‘check’ with their wetlands capacity. By the mid-1980’s, however, prices had fallen sharply, culminating in declining annual harvests and an increasing population. Because of their feeding habits, the increased nutria population has resulted in a substantial amount of wetland degradation. In this thesis, a long-run bioeconomic …

Hemodynamic And Ocular Responses To Caloric Stimulation And Age-Related Disparities, Melissa J. Deveer Jan 2005

Hemodynamic And Ocular Responses To Caloric Stimulation And Age-Related Disparities, Melissa J. Deveer

LSU Master's Theses

Age-related declines in vestibular function affect balance and coordination in older adults. Of perhaps equal importance, but less understood, are the potential implications of vestibular degeneration on cardiovascular homeostasis. Recent evidence suggests that the semi-circular canals, a section of the vestibular system, may be involved in the vestibulosympathetic reflex (VSR), but the extent to which the aging of the semi-circular canals interferes with cardiovascular homeostasis is unknown. Activation of the intact VSR results in increases in tonometric blood pressure (TBP) and heart rate (HR) as well as decreases in cardiac output (Q) and pre-ejection period (PEP). The purpose of this …
