Grace Street Senior Center, Virginia Brockett
Theses and Dissertations
Societal structure has changed through the decades to reflect a contemporary interest in youth culture. The nuclear family, where generations lived under one roof no longer exists, leaving the elderly on the periphery of the family structure. Where once grandparents, parents and children all cohabitated, now the oldest family members are relegated to solitary retirement and aging alone. Studies have shown that "depression in the elderly is more likely to lead to suicide. Elderlywhite men are at greatest risk, with suicide rates in people ages 80 to 84 more than twice that of the general population. The National Institute of …
Examining Student Engagement And Its Influence In A Social Contextual Model Of Adolescent Health Behavior Change, Ian Joseph Wallace
Examining Student Engagement And Its Influence In A Social Contextual Model Of Adolescent Health Behavior Change, Ian Joseph Wallace
Theses and Dissertations
Current theoretical models of health behavior change frequently serve as the theoretical backdrop to adolescent health promotion programs. Yet, despite that each main theory was developed with adults and for adults, appropriate and necessary changes for adolescents are often neglected. The unique values, priorities, and abilities of adolescents are important and therefore necessary to consider during health promotion efforts. The present study explored student engagement, a unique adolescent need that has been shown to facilitate achievement in academic environments. Evidence from the psychological and educational literatures suggests that engagement may uniquely influence the process of health behavior change for adolescents. …

Theses and Dissertations
Vaccination programs using live whole cell vaccines are presently being used to control outbreaks and to help protect flocks from field strains of Mycoplasma gallisepticum. The primary goal of the present study was to investigate the effects of a ts11-strain M. gallisepticum inoculation alone, and in conjunction with F-strain M. gallisepticum overlays at 22 or 45 weeks of age during lay. In this study, it was shown that a pre-lay ts11 vaccination had a broad range effect on the physiology of the commercial layer without affecting overall performance. The timing of an overlay vaccination using F-strain M. gallisepticum during lay …
Disease Management Strategies For Controlling Spring Dead Spot And Frequency Of Occurrence Of The Causal Organism Ophiosphaerella Korrae On 'Tifway' Bermudagrass (Cynodon Dactylon X C. Transvaalensis), Hunter D. Perry
Theses and Dissertations
Spring dead spot (SDS) is the most destructive disease of bermudagrass and its hybrids, affecting intensively managed bermudagrass turf that is at least three years old. This bermudagrass disease is most prevalent in the United States where winter temperatures become cold enough to induce dormancy. The symptoms of SDS appear as sunken, necrotic patches of turf ranging from several centimeters to greater than 0.5 m in diameter. Field studies were conducted at Old Waverly Golf Club in West Point, MS on a Tifway bermudagrass fairway beginning January of 2005 and concluding December of 2006 to determine the frequency and the …

Effects Of Nitrogen Deficiency On Plant Growth, Leaf Photosynthesis, And Hyperspectral Reflectance Properties In Castor (Ricinus Communis L.), Satyasai Kumar Matcha
Theses and Dissertations
Influence of nitrogen (N) deficiency on castor cv. ‘Hale’ growth, physiology, and leaf reflectance properties were investigated. Treatments imposed were complete Hoagland’s nutrient solution (control, 100N), reduced N to 20% of the control (20N) and withheld N from the solution (0N) from 34 to 66 days after sowing (DAS) in 12-L pots grown out doors. N deficiency significantly reduced leaf area, chlorophyll and photosynthesis resulting lower total biomass. Leaf and stem growth rates were more sensitive to leaf N concentration than photosynthesis and leaf addition rates. N deficiency stress increased leaf reflectance at R555 and R715 nm and caused a …

Effects Of Soil Region, Litter Size, And Gender On Morphometrics Of White-Tailed Deer Fawns, Amy Castle Blaylock
Theses and Dissertations
Previous research documented that white-tailed deer body mass and antler size varied across physiographic regions of Mississippi. Deer from regions with greater soil fertility had greater body mass and antler size; however, this information is known only for individuals 6 months of age and older. I monitored birth mass and skeletal size of fawns produced by bred, adult, female white-tailed deer transplanted from the Delta, Thin Loess (Loess), and Lower Coastal Plain (LCP) soil regions to fawn in the Mississippi State University Rusty Dawkins Memorial Deer Unit. I evaluated the effect of soil region of origin, litter size, and fawn …
An Investigation Into The Techniques Of Neutralization Theory And Their Effects On Compulsive Consumption Behavior, Collin Z. Barnes
An Investigation Into The Techniques Of Neutralization Theory And Their Effects On Compulsive Consumption Behavior, Collin Z. Barnes
Theses and Dissertations
Due to societal and economic costs caused by compulsive consumption behavior, specifically problem drinking and overeating, a search has been launched for a cognitive explanation for the ‘deviant’ behaviors and the motivations that cause these behaviors to continue. This dissertation attempted to develop a better understanding of continued compulsive consumption behavior by investigating consumers’ use of the techniques of neutralization theory. Based on methodological concerns in neutralization research, the development of reliable and valid measures of the five techniques of neutralization theory were described and used to examine their moderation of compulsive consumption behavior and its relationship with social norm …
Selection For Reduced Seed Dormancy In Seven Native Grass Species, Kyle Bradley Holmberg
Selection For Reduced Seed Dormancy In Seven Native Grass Species, Kyle Bradley Holmberg
Theses and Dissertations
Lowland switchgrass (Panicum virgatum), big bluestem (Andropogon gerardii), indiangrass (Sorghastrum nutans), upland switchgrass (Panicum virgatum), little bluestem (Schizachyrium scoparium), beaked panicum (Panicum capillare), and purpletop (Tridens flavus) all show strong signs of seed dormancy which contributes to extremely poor field establishment. The objective of this work was to reduce seed dormancy by selecting individuals that exhibited reduced pre-stratification dormancy in laboratory tests. The classical breeding method of phenotypic recurrent selection was used to enhance germination. Of the three tall-stature species, lowland switchgrass made the greatest improvement in pre-stratification germination, followed by indiangrass and big bluestem. The four short stature species …

Sensory And Quality Assessment Of Grazing Standing Corn Versus Commercially Feed Lot Finished Beef, Husniye Imamoglu
Theses and Dissertations
This study compared feed lot finished beef and grazing standing corn beef from young steers for sensory acceptance, sensory quantitative descriptive analysis attributes palatability and Warner–Bratzler shear force values. In comparing both feeding treatments results indicated no differences (P > 0.05) between feeding treatments for all attributes including appearance, aroma (with handheld) and (with sniff bottle), texture, flavor and basic taste. However, there was difference (P < 0.05) in flavor, offlavor for different feeding systems by panelists. Analysis of variance for Warner- Bratzler shear force values revealed no differences (P > .05) between steaks from two treatments. Based on this research, the meat industry may wish to provide the consumer with the option of choosing beef that was traditionally feed lot finished or beef finished by …
Relationships Between Volatile Flavor Compounds, Sensory Descriptors And Consumer Acceptability Of American Dry-Cured Ham, Alessandra Julian Pham-Mondala
Relationships Between Volatile Flavor Compounds, Sensory Descriptors And Consumer Acceptability Of American Dry-Cured Ham, Alessandra Julian Pham-Mondala
Theses and Dissertations
The relationships between volatile flavor compounds, sensory descriptors and consumer acceptability were determined for eight commercial American dry-cured hams using external preference and flavor mapping. The majority of consumers preferred (p<0.05) hams that had more intense caramelized, smoky, savory and molasses aromas as well as more intense sweet and savory flavors. Sixteen aroma impact compounds were identified from the headspace volatiles of dry-cured hams. The consumers with the highest acceptability scores preferred (p<0.05) hams that were characterized by 4-methyl-2-methoxyphenol (sweet ham), 4-ethyl-2-methoxyphenol (sweet ham), 2-methoxyphenol (smoky, cocoa), 2,6-dimethoxyphenol (smoky ham, savory) and 2uranmethanol (burnt meat, vitamin). Fourteen percent of consumers preferred (p<0.05) two hams that were characterized by methional (baked potato). Consumer acceptability scores were lower for hams either characterized by methanethiol (sulfur), carbon disulfide (sulfur), 2-butanone (sweet), 3-methylbutanal (malty, fermented), 2-heptanone (burnt meat, vitamin), hexanal (cut grass), benzeneacetaldehyde (floral), 1-octen-3-ol (mushroom) or characterized by benzaldehyde (burnt meat, cooked meat) and limonene (citrus).
Proteomic Analysis Of Listeria Monocytogenes, Sana Mujahid
Proteomic Analysis Of Listeria Monocytogenes, Sana Mujahid
Theses and Dissertations
Listeria monocytogenes is a deadly, Gram-positive foodborne pathogen that is ubiquitous in the environment. The bacterium expresses a number of virulence and stress adaptation proteins that support its pathogenic capabilities. Two-dimensional gel electrophoresis (2-DE) was used to map L. monocytogenes surface proteins, which play a central role in virulence, and to examine protein expression by L. monocytogenes grown on ready-to-eat meat, an important source of Listeria infections. A novel method for solubilization of surface proteins from L. monocytogenes for 2-DE was developed. Additionally, the unique proteome expressed by L. monocytogenes grown on a meat matrix was uncovered. The developed solubilization …

The Effect Of Febrile Temperature On Plasmodium Falciparum, Heidi Sue Porter
The Effect Of Febrile Temperature On Plasmodium Falciparum, Heidi Sue Porter
Theses and Dissertations
Previously it has been shown that cultures of Plasmodium falciparum died following exposure to a febrile temperature of 40°C, as demonstrated by a decrease in parasitemia of the following generation. In the current study, the effect of 40°C treatment on culture media, erythrocytes, and parasite glucose consumption, were ruled out as possible influences on parasite death, demonstrating that 40°C impacted the parasites directly. Metabolic profiling of DNA synthesis, protein synthesis, and glucose utilization during exposure to 40°C clearly indicated that febrile temperatures had direct effect on major metabolic pathways and parasite development, beginning 20-24 hr after erythrocyte invasion. The ring …
Registered Dietitian Dress And The Effect Of Dietitian Dress On Perceived Professionalism, Connie Lynn Packer
Registered Dietitian Dress And The Effect Of Dietitian Dress On Perceived Professionalism, Connie Lynn Packer
Theses and Dissertations
People use others' dress to make assumptions, including how they believe the wearer will behave. Observers then adjust their behavior in response to the anticipated behavior of the wearer. Physician or nurse dress affects the degree to which patients perceive the medical professional as confident, experienced, competent, mature, trustworthy, and professional. Dietitian dress has not been studied. Our purpose was to identify 1) the current level of formality of dress of registered dietitians (RD), 2) characteristics of dress codes, 3) the effect of RD dress on patient/client perceptions of professional traits, and 4) the level of formality at which an …
Calcium Dynamics Affecting Egg Production, Skeletal Integrity, And Egg Coloration In Ring-Necked Pheasants (Phasianus Colchicus), Landon R. Jones
Calcium Dynamics Affecting Egg Production, Skeletal Integrity, And Egg Coloration In Ring-Necked Pheasants (Phasianus Colchicus), Landon R. Jones
Theses and Dissertations
These 4 chapters represent manuscripts formatted for submission to journals based on an experiment conducted on Ring-necked Pheasants (Phasianus colchicus). Calcium limits the distribution of this species, which produces 7-15 eggs per clutch. They may renest up to 5 times per breeding season on a diet low in calcium. The first chapter examines egg production in laying hens on 7 different diets from 0.19-4.47% calcium in the absence of calcium loading. Calcium-loaded pheasants store calcium in medullary bone before an experiment and can draw on this surplus during egg production, possibly skewing experimental results. We measured egg production, egg characteristics, …
