Wetland And Nest Scale Habitat Use By The Four-Toed Salamander (Hemidactylium Scutatum) In Maine, And A Comparison Of Survey Methods, Rebecca J. Chalmers

Electronic Theses and Dissertations

Conserving amphibian populations requires knowledge of a species and its habitat relationships. The four-toed salamander (Hemidactylium scutatum) is listed as Special Concern in Maine and 11 additional states and provinces, Threatened in Illinois, and Endangered in Indiana (Appendix A). Little is known of H. scutatum ecology despite the species' extensive range. Infrequent sightings of H. scutatum throughout its range may indicate either low numbers or that the species' behavior make detection difficult. Records for H. scutatum in Maine existed from only 32 sites before my study, and the total number of occurrences of this species in Maine is …

Environmental Conservation On Agricultural Working Land: Assessing Policy Alternatives Using A Spatially Heterogeneous Land Allocation Model, Kelly M. Cobourn

Electronic Theses and Dissertations

Multifunctionality refers to the ability of agricultural systems to produce an array of non-market goods and services in addition to market commodities. This thesis focuses explicitly on the provision of environmental benefits, through reduced soil erosion and fertilizer applications, by agricultural producers. Soil erosion and nutrient contamination from agricultural production are the foremost contributors to ground and surface water degradation in the United States. Reducing their production implies gains in social welfare, but may generate significant private losses to producers. The objective of this analysis is to quantify the tradeoff between environmental improvements and producer welfare and to examine the …

Temporal Variability Of Satellite-Derived Chlorophyll And Sea Suface Temperature In The California Current, Kasey Legaard

Electronic Theses and Dissertations

Physical forcing and biological response within the California Current coastal upwelling system are highly variable over a wide range of scales. Satellite remote sensing offers the only feasible means of quantifying this variability over the full extent of this current system. Here we quantify and compare patterns of physical and biological variability acting over seasonal, interannual and dominant intraseasonal time scales throughout the California Current System using more than five years (1997-2003) of daily SeaWiFS chlorophyll and NOAA/NASA AVHRR Oceans Pathfinder SST imagery. Mean seasonal cycles were modeled as the sum of annual and semiannual harmonics. Interannual variability was estimated …

Generating Linear Orders Of Events For Geospatial Domains, Suzannah Hall

Electronic Theses and Dissertations

Events in the world do not occur in neat chronological order, but may take place, for example, during or overlapping each other, or as simultaneous events. Efficient summaries of real-world events are important in many disciplines and require events to be modeled in a linear fashion. This thesis focuses on modeling events as intervals and using relations between the events to derive linear orders from more complex partially ordered sets. A method is developed for mapping Allen's thirteen temporal relations to only two relations, before and equals, which allow a linear ordering of all events present in the set. This …

Risk Perceptions Of Adults In The Town Of Unicoi, Tennessee, Regarding The Possible Building Of A Uranium Enrichment Plant., Shannon Kathleen Sellards

Electronic Theses and Dissertations

A prolonged siting controversy for a uranium enrichment facility has occurred in the Town of Unicoi, Tennessee. One hundred-seventy residents of Unicoi were interviewed using a questionnaire regarding the building of a proposed uranium enrichment facility for Unicoi. The questionnaire sought to determine relationships between residents’ risk perceptions and 18 variables. When the Fisher’s exact procedure was applied at α< 0.05, the results indicated several associations. Odds ratio measured the strength of association. Results are reported as crude measures of association. Risk perceptions were influenced by the choice of possible locations for the facility [p=0.0003; OR=32.6]. Residents' risk perceptions were associated with a history of working with nuclear materials [p=0.0476; OR=3.2]. Finally, risk perceptions were associated with residents' beliefs that the nuclear facility would affect their health [p=0.0001; OR=18.8]. These results are discussed in light of risk perception and communication theories.

Inducing Knowledge By Enduring Experience: The Function Of A Postmodern Pragmatic Aesthetic In Linda Montano's "Living Art"., Alisa Anne Brandenburg

Electronic Theses and Dissertations

In Has Modernism Failed? (1984), Suzi Gablik calls for a postmodern art that has preserved the values that modernism lost over the 20th century, stating that only through "direct knowing" may we be shocked out of art-for-art's-sake. In Art As Experience (1934), John Dewey similarly proposes that "thinking is a kind of doing," recommending an instrumental art in one's drive to better him/herself.

Contemporary artist Linda Montano challenges the status quo by exploring the nature of art beyond its material value. In her Living Art performances (1970-1986), Montano creates a postmodern pragmatic aesthetic that is conducive to the unique …

A Characterization Of Micromanipulator Controlled Dry Spinning Of Micro- And Nanoscale Polymer Fibers., Scott Berry

Electronic Theses and Dissertations

No current microfabrication technique exists for producing room-temperature, high-precision, point-to-point polymer nanofibers in three dimensions. Producing rounded structures in a third dimension is particularly difficult to accomplish with conventional planar microfabrication techniques. Therefore, the purpose of this study is to characterize a novel method for fabricating such structures. In this investigation, PMMA micro- and nano-fibers have been fabricated using a technique which involves drawing a solvated polymer bridge between two liquid pools with a stylus positioned by an ultra-high-precision micromill. The solvent in the solution bridge rapidly evaporates, leaving a suspended PMMA fiber between the two pools. In order to …

The Heart Of The Matter : The Gendered Relationship Of Altruism And Marital Happiness., Natalie Jane Brinton Call 1978-

Electronic Theses and Dissertations

In light of western cultural trends toward individualism, the presence of altruistic marital attitudes and behavior is examined as a predictor of marital happiness. Most quantitative studies exploring correlates of marital happiness use the same underlying concept of asking participants how their spouses' actions help them obtain marital happiness. Specifically, this research departs from convention by using a respondent's own level of altruism to predict his or her own marital happiness. Quantitative data gathered in the Louisville Metropolitan Survey 2004 is used for the project. Several methods of analysis find support for ties between certain manifestations of marital altruism and …
