This study also applied the theory of organizational capture to the ADC program to test its utility in explaining the attitudes and behaviors of employees. Results were based on a survey of ADC employees conducted in January 1995.
Survey responses were analyzed to explore associations between …
The Influence Of Forest Fragmentation And Landscape Pattern On American Martens And Their Prey, Christina D. Hargis
The Influence Of Forest Fragmentation And Landscape Pattern On American Martens And Their Prey, Christina D. Hargis
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Habitat fragmentation occurs when large tracts of an orginal habitat are replaced by smaller patches of two or more habitat types, largely through human activities. I studied the behavior of six measures of landscape pattern that seemed appropriate for quantifying fragmentation, and used these measures to investigate the effects of forest fragmentation on American martens (Martes americana) and their prey. The measures I selected were edge density, contagion, mean nearest neighbor distance between patches, mean proximity index, perimeter-area fractal dimension, and mass fractal dimension. To test the behavior of these measures with a variety of landscape patterns, I …
Ecology, Economy And Ecotourism: Sustaining People And The Environment, Richard Snow
Ecology, Economy And Ecotourism: Sustaining People And The Environment, Richard Snow
Masters Theses & Specialist Projects
Tourism is the world's largest industry. The fastest growing segment of the travel and tourist trade is ecotourism. The concept of sustainable development insists that humans cooperate with nature in the search for an ecological economy which can support present and future populations. Ecotourism attempts to attain this elusive goal by preserving ecosystems while generating revenue for local communities. In this study, the researcher examines the positive and negative effects of ecotourism on people, culture, and landscape. An analysis of tourism data seems to suggest that developing countries, which are popular ecotour destinations, are benefitting economically and ecologically from properly …
Environmentalism In The United States: An Evolving Perspective, Mary Snow
Environmentalism In The United States: An Evolving Perspective, Mary Snow
Masters Theses & Specialist Projects
The purpose of this study is to investigate environmentalism in the United States. The dimension of perspective receives considerable attention. The prevailing perspective by a society regarding the importance of the health of the natural world greatly influences the degree of support of environmental organizations, environmental policy, as well as the direction charted for the future of that society. The perspectives of the Native Americans and the dominant European cultures which arrived in North America are presented and contrasted. It is supposed that the perspective which prevails in the United States regarding the importance of the natural world is evolving. …
Identification Of Optimal Locations For Sampling Ground Water For Pesticides In The Mississippi Delta Region Of Eastern Arkansas, H. S. Lin, H. D. Scott, J. M. Mckimmey
Identification Of Optimal Locations For Sampling Ground Water For Pesticides In The Mississippi Delta Region Of Eastern Arkansas, H. S. Lin, H. D. Scott, J. M. Mckimmey
Arkansas Water Resources Center Technical Reports
Concerns about the presence of pesticides in the Mississippi River Valley alluvial aquifer in the Arkansas Delta have generated the need to develop a map of ground water vulnerability for this region comprised of approximately 10 million acres. Based on the availability of digital data and the scale of this study. we used a modified Pesticide DRASTIC model in a GRASS GIS environment to identify areas that were physically more sensitive to pesticide contamination than other areas within the Delta. Spatial distribution of pesticide loading was estimated from pesticide application rates in different crops and crop distribution map interpreted from …
An Ecological History Of Tintic Valley, Juab County, Utah, Jeffrey A. Creque
An Ecological History Of Tintic Valley, Juab County, Utah, Jeffrey A. Creque
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This work was a case study of historical ecological change in Tintic Valley, Juab County, Utah, an area historically impacted by mining and ranching activities common to much of the American West. The temporal framework for the study was approximately 120 years, the period of direct Euroamerican influence. In recognition of the ecological implications of cultural change, however, the impacts of prehistoric and protohistoric human activity on study area landscape patterns and processes were also explicitly addressed.
The study included a narrative description of historic land uses and ecological change in Tintic Valley, and examined the changes in landscape patterns …
A Test Of An Alternate Calibration Matrix For Niosh Method 7300, Robert T. Vitek
A Test Of An Alternate Calibration Matrix For Niosh Method 7300, Robert T. Vitek
Community & Environmental Health Theses & Dissertations
The purpose of this study was to determine if the analytical results (when determining cadmium, lead, and zinc concentrations) for air sample filters prepared and analyzed according to N:OSH Method 7300, differ significantly, from those obtained when the instrument is calibrated using EPA Method 200.7 acid matrix standards. The null hypothesis was that no statistically significant difference, measured at the 95% confidence level, would exist between results obtained from the two calibration standards. Careful standard and sample preparation, the use of an internal standard, and the application of working standard and working internal standard correction factors served to isolate the …
Evaluation Of Propane Exploders As White-Tailed Deer Deterrents, J. L. Belant, T. W. Seamans, C.P. Dwyer
Evaluation Of Propane Exploders As White-Tailed Deer Deterrents, J. L. Belant, T. W. Seamans, C.P. Dwyer
United States Department of Agriculture Wildlife Services: Staff Publications
In response to increased white-tailed deer (Odocoileus virginianus) depredation of agricultural crops and encroachment on airports, we evaluated the effectiveness of systematic and motion-activated propane exploders as deer frightening devices. We conducted three experiments in a 2200 ha fenced facility in northern Ohio with high (91/km2) deer densities during 1994-1995. Systematic exploders were calibrated to detonate once at 8 to 10 min intervals, whereas motion-activated exploders detonated 8 times/deer intrusion. Systematic propane exploders were generally ineffective, deterring deer from corn for <2 days only, whereas motion-activated exploders repelled deer for O-6 weeks. Repellency of motion-activated exploders varied seasonally, possibly in response to variations in deer density, availability of alternate food, or reproductive and social behavior. We recommend motion-activated exploders over systematic exploders as deer frightening devices for crop damage mitigation and on airports; however, systematic exploders may have utility for short-term (a few days) use.

The Barriers Present In More Developed Countries And Less Developed Countries Slowing The Implementation Of Substainability, Luke Giovine
UNLV Theses, Dissertations, Professional Papers, and Capstones
In 1996 the natural resource base of the world is being depleted at a rate far below the sustainable level. This is very evident in less developed countries (IDC), where raw limited natural resources are being poorly utilized and/or exported to more developed countries (MDC). The More Developed Countries such as the United States, Japan, and Germany use a high amount of natural resources and energy to maintain their material Standard Of Living (SOL), and this is at rates above what their own country can sustain with its own natural resources within its own borders. Both MDC's and LDC's are …

ISTEA significantly changed the law governing metropolitan transportation planning. In response to the changes introduced by ISTEA, FHWA and FTA issued revised planning regulations on October 28, 1993, setting new requirements for the transportation planning processes. The requirements are presented in 23 CFR Part 450 and 49 CFR Part 613, Statewide and Metropolitan Planning Final Rule. The Clean Air Act Amendments of 1990 (CAAA) also imposed rigorous new transportation planning requirements in metropolitan areas, particularly those that are designated nonattainment or maintenance areas for air quality. In support of the implementation of the revised regulations, FHW A and FTA jointly …
