Perceptions Of Current Club Managers Regarding College Coursework Necessary For Preparation For A Career As A Club Manager, Candice E. Clemenz

Masters Theses

The purpose of this research was to gather and interpret the perceptions of current club managers regarding the college coursework that they believed was necessary to prepare a student for a career as a club manager. First, a list of course areas was developed via a review of hospitality curriculums, and conversations with industry professionals. The list was used to design Part 1 of a questionnaire that featured 13 course areas with corresponding descriptive and ascending levels of competencies. Instructions clearly directed club managers to select the highest level of competency for each course area that they thought should be …

Arthropods Associated With Leaf Litter Of Fraser Fir In The Great Smoky Mountains National Park, David Norman Hughes

Masters Theses

Fraser Fir, Abies fraseri (Pursh) Poiret, is a southern endemic conifer species restricted to the higher elevations of the southern Applachian mountains. This forest type is currently threatened by the balsam woolly adelgid, Adelges piceae (Ratzeburg), an exotic pest species native to Europe. This insect has destroyed more than 95% of the mature Fraser fir within the boundaries of the Great Smoky Mountains National Park (GRSM). The adelgid damages Fraser fir by disrupting the flow of nutrients in the vascular tissues of the bark. This disruption is due to abnormal growth of the vascular tissues resulting from a reaction to …

Effect Of Lead On Globin Mrna In Vivo And In Vitro, C. A. Aethranis

Masters Theses

The total amount of mRNA recovered from Pb²⁺-treated rabbits was not significantly influenced by lead but dose-dependent loss of template activity of the poly A+ fraction was observed. These observations lead to the conclusion that the messenger RNA of rabbit reticulocytes exposed to Pb²⁺ in vivo was damaged and inactivated without extensive depolymerization of the mRNA.

In vitro experiments on the effect of Pb²⁺ on purified rabbit globin mRNA were also performed. After incubation with Pb²⁺ at micromolar concentrations, the 7-methyl guanosine cap was removed from the mRNA, while damage to the remainder of the …

Identification And Evaluation Of Nutrition Education Materials For Use In Kindergarten, Mary Katherine Powers

Masters Theses

The purpose of this project was to determine the extent to which nutrition education lesson plans address the objectives covered in a kindergarten curriculum that is representative of other kindergarten curricula across the United States. Incorporating nutrition education into the kindergarten curriculum can allow children to be exposed to nutrition more often without adding additional subject areas and time to teachers' busy schedules.

We recruited volunteer teachers in a metropolitan school system and provided continuing education on the Dietary Guidelines. Teachers determined that four of the Dietary Guidelines were developmentally appropriate for kindergarten students and evaluated 400 lesson plans as …

The Population Biology And Demography Of Cimicifuga Rubifolia Kearney And The Genetic Relationships Among North American Cimicifuga Species, Rebecca Ann Cook

Doctoral Dissertations

In this beginning study of the population biology of Cimicifuga species, the life history and demography of the long-lived herbaceous perennial, Cimicifuga rubifolia Kearney, were investigated, the genetic structure of some of its populations was studied, and an investigation of the genetic relationships among the North American species was begun.

The life history and demography were monitored in two populations, one of approximately 1400 individuals (1987-1990) and the second of about 400 individuals (1988-1990). A model of leaf area was used to determine the leaf area (photosynthetic size) of individuals and this was followed during the study. Relationships between the …

The Vegetation Of Great Smoky Mountains National Park: Past, Present, And Future, Mark D. Mackenzie

Doctoral Dissertations

This research investigates the vegetation of Great Smoky Mountains National Park (GRSM) using three different techniques: 1) analysis of vegetation data collected circa 1930, 2) remote sensing of current (1984) vegetation using Landsat Thematic Mapper (TM) satellite imagery, and 3) the integration of gradient analysis with forest succession modeling.

Analysis of the 1930's data revealed that Castanea dentata was the dominant species in the GRSM at that time, even with the introduction of the chestnut blight to the park in 1926. Classification of the 1930's plot data identified 16 unique vegetation types ranging from the low elevation, xeric Pinus rigida …

Population Ecology Of Black Bears On Camp Lejeune, North Carolina, Carmen A. Lombardo

Masters Theses

Fifteen black bears (Ursus americanus) were captured 24 times on Marine Corps Base Camp Lejeune, North Carolina, during 1988 and 1989. Females dominated the capture sample, but age did not differ between the sexes (P=0.31). No subadult males were captured during the study. Mean litter size was 2.2 (n=6) with females attaining primiparity at age 4. Breeding may occur at age 3; den observations-and teat development suggested previous parturition in a four-yearold. Estimated annual survival rates were 0.77 for males, 0.69 for females, and 0.53 for cubs. Causes of mortality included vehicle collisions (n=S), research (n=l), and legal …

Masters Theses

(From the Introduction: Abbreviated

The objectives of this study are to determine the effects of an long-term (30 day) oral diet containing SCT on the intestinal mucosa, plasma substrates, and growth and development in rats.
