An Analysis Of Topographic Effects On Landsat Thematic Mapper Image Using Digital Terain Data, Xiaomin Liu

Masters Theses

A comprehensive literature review on the simulation and corrections of topographic variations in remote sensing data was presented. The effects of topography on the scene radiance of LANDSAT thematic mapper (TM) image were examined in the context of the remote sensing of vegetation m Great Smoky Mountains National Park (GSMNP).

To simulate the image intensity component due to varying orientation of surface elements, two reflectance models were adopted to generate the synthetic images from a Digital Elevation Model (DEM). Visual and analytical procedures were developed to register the TM image to the DEM data.

The dark tones of scene radiance …

The Importance Of Competition For Food Resources In The Interaction Between Brook Trout (Salvelinus Fontinalis) And Rainbow Trout (Salmo Gairdneri), William E. Ensign

Masters Theses

The last 80 years have seen a drastic reduction in the range of the brook trout (Salvelinus fontinalis) the only salmonid native to the Southern Appalachians. Much of this range reduction is directly correlated with increases in the range of the introduced rainbow trout (Salmo gairdneri). The purpose of this study was to determine if competition for food resources plays a significant role in this interaction.

Stomach contents were obtained from sympatric and allopatric populations of brook and rainbow trout during June, July, August and September of 1987. Terrestrials comprised the majority of food items in …

Prediction Of Forest Type And Productivity Index On Disturbed Sites In Great Smoky Mountains National Park, Charlotte Pyle

Masters Theses

A study was conducted in a portion of the permanent vegetation plots established by Uplands Field Research Laboratory in Great Smoky Mountains. The plots were located in the northwestern portion of the park in the vicinity of Cades Cove and Tremont on sites previously disturbed by chestnut blight, logging, fire, farming activities, and livestock grazing. Estimated plot productivity, and data on vegetation, soils, and topographic parameters were available from previous study of these plots. The purpose of the present study was to develop methods to predict forest cover type and plot productivity index score using site and disturbance history-related factors. …

A Survey And Distributional Analysis Of The Park Coccoid Fauna Of The Great Smoky Mountains National Park And Evirons, John Keith Watson

Masters Theses

This comprehensive study on the coccoids (Homoptera: Coccoidea) of the Great Smoky Mountains National Park (GSMNP) resulted in the collection of fifty-three species representing six families from which seven new collection records for Tennessee were obtained. Six species were discovered that possibly represent new species. Analysis of distribution and host relationships are provided. Keys to the families, genera, and species are provided as well as descriptions of scale covers or tests and distinguishing morphological characters of the adult females.

A higher number of species were collected at lower elevational vegetative types and decreased inversely with elevation (y = 17.104 - …

The Influence Of Job Characteristics On Organizational Commitment To Job Satisfaction Of Foodservice Employees, Carole M. Herman

Masters Theses

The purpose in this study was to determine the relationship among job characteristics, organizational commitment, and job satisfaction of hospital foodservice employees. A 4-part questionnaire was developed including the 30-item Job Characteristics Inventory, 15-item Organizational Commitment Questionnaire, 6 items related to job satisfaction, and 7 demographic items. Separate written questionnaires were administered to 45 supervisors and 172 employees in dietary departments in 11 East Tennessee hospitals. Data from school and university setting was collected from previous studies.

The reliability for the instruments (Cronbach's alpha) was .89 for employees and .87 for supervisors. Multiple regression analyses were used to test research …

Growth Patterns Of Red Spruce Populations In Two Spruce-Fir Forest Stands In The Great Smoky Mountains National Park, Xinyuan Wu
