Aspects Of Swift Fox Ecology In Southeastern Colorado, David E. Andersen, Thomas R. Laurion, John R. Cary, Robert S. Sikes, Mary A. Mcleod, Eric . M. Gese

United States Department of Agriculture Wildlife Services: Staff Publications

We studied the ecology of swift fox on the Pinon Canyon Maneuver Site (PCMS) in southeastern Colorado from March 1986 to September 1987. Forty-two foxes were captured 162 times; 23 were radio-collared. Mean minimum convex polygon home range size of 5 adult swift fox was 29.0 km² (range = 12.8 to 34.3 km²) and although home ranges of adjacent social groups overlapped, core areas described by 50% harmonic means were almost entirely exclusive. Swift fox diet (as determined from scats) consisted primarily of small and medium-sized mammals (monthly mean % volume = 64%), arthropods (Χ̅ = 19%), …

Statistical Probability As A Metaphor For Epistemological Probability, L. David Ritchie

Communication Faculty Publications and Presentations

The metaphor, "epistemological probability is statistical probability" is traced to the origins of probability theory. Related metaphors appear both in everyday discourse about social processes, and in social scientific argumentation, often disguised as literal claims. Gambling provides a familiar vehicle for expressing the uncertainties associated with social interactions, and with social science research. Examples are drawn from reports of research on media effects, from everyday conversations, and from political communication.

A Solvent-Free Claisen Condensation Reaction For The Organic Laboratory, John J. Esteb, Matthew B. Stockton

Scholarship and Professional Work - LAS

An experiment involving the Claisen condensation reaction for a first-year organic chemistry laboratory is presented. Claisen condensations are routinely covered in organic textbooks but owing to the long reaction times required to reach equilibrium in solution they are seldom explored in the undergraduate teaching laboratory. In this experiment, potassium tert-butoxide and ethyl phenylacetate are heated to 100 °C for 30 minutes under solvent-free conditions to produce 2,4-diphenyl acetoacetate in 80% yield. The solvent-free nature of this procedure greatly reduces the quantity of waste generated by students relative to typical carbonyl condensation experiments.

Free Solution Electrophoresis Measurements And Their Theoretical Relationships To Net Protein Valence, Jennifer A. Durant

Doctoral Dissertations

Biochemical solutions are composed to a large degree of charged molecules (proteins, DNA, dissolved salts, etc) which can interact and therefore exert a force on each other. Analytical determination of the valence of biological macro-ions contributes to our understanding of the forces involved in both intra- and inter-molecular interactions. This dissertation uses two free solution techniques, membrane confined electrophoresis (MCE) and capillary electrophoresis (CE), to study valence in the context of a series of charge mutants of T4 lysozyme and RNase Sa. The use of these mutants allows attribution of the changes in electrophoretic behavior entirely to changes in charge. …

The Effects Of Providing Mathematical Problem -Posing Experiences For K--8 Pre-Service Teachers: Investigating Teachers' Beliefs And Characteristics Of Posed Problems, Todd August Grundmeier

Doctoral Dissertations

This study incorporated problem posing into a mathematics content course for preservice elementary and middle school teachers by extending George Polya's (1957) problem solving heuristic to include problem re-formulation and by having participants pose problems from sets of given information. The course provided pre-service teachers with a new mathematical perspective and this research examined participants' problem posing, beliefs about mathematics, and beliefs about the teaching and learning of mathematics.

Study participants were enrolled in a mathematics content course for pre-service teachers at the University of New Hampshire. There were twenty students in the course and nineteen agreed to be participants …

Design And In Situ Testing Of A Piezometer System To Measure Earthquake -Induced Pore -Pressure Changes, Robert Farrell

Doctoral Dissertations

Pore pressure changes have been measured in fine sand deposits that are known to have liquefied during earthquakes. Some of the measured signals have not been similar to what was expected during earthquake-induced liquefaction. Using artificially generated signals, several investigators have attempted to determine if existing piezometer fields designed to measure earthquake induced pore pressure changes are operating correctly. The signals generated during one investigation were not similar to those expected from an earthquake. In another investigation, while the generated signals were similar to ones expected from an earthquake, the results were not reproducible; the generated signals damaged the aquifer …

Satellite Indices Of Fluvial Influence In Coastal Waters, Joseph E. Salisbury Ii.

Doctoral Dissertations

In this dissertation a suite of satellite, discharge and in-situ measurements is used to explore the spatio-temporal distribution of terrestrial constituents in coastal environments. The covariance between riverine delivery of optically active constituents and the corresponding optical variability in neighboring coastal waters for the Mississippi and Orinoco Rivers is documented. From this work, satellite-based indices of fluvial influence (IFI), are developed which contain information on the spatial extent of riverine constituents in coastal waters. The IFI is defined as the correlation between time series of riverine discharge and an ocean color satellite-derived property in the region proximal to a river's …

Living The Stereotype: Connections Between Male Behavior And Male Images, Andrew Paul Smiler

Doctoral Dissertations

This project examined some linkages and discrepancies between theories that describe the acquisition of gender typical attributes in childhood with theories that describe the maintenance of those attributes in adulthood. This perspective included the idea that there are several well known ways of enacting masculinity, related to well known stereotypes (e.g., jock, business, sensitive new age guy), and highlighted within sex variability. Because a distinction between biological sex and gender was made, the sample was not restricted to males despite focusing on the masculine. One focus of the project was the consistency with which an individual enacts a particular stereotypical …

Knowledge, Inquiry, Action: Teacher Collaboration At Prospect Center's Summer Institute, Karen Hendrickson Woolf

Doctoral Dissertations

This two-year study describes the work of approximately thirty educators, kindergarten/post-secondary, who attend the Summer Institute on Descriptive Inquiry and November Conference under the auspices of The Prospect Archive and Center for Education and Research in North Bennington, Vermont. The purpose of this study is to portray the experience of collaborative inquiry using Prospect Center's descriptive processes.

Teacher network groups generally center around specific content areas such as language arts or science. In contrast, Prospect Center is an independent national network of educators committed to guided observation and disciplined description as a grounding for teaching practice and inquiry. Generated by …

Wavelet Analysis Of Ulf Magnetospheric Waves, Edward Scott Brennison

Doctoral Dissertations

Wavelet analysis is used to analyze magnetometer data and is compared to the traditional spectrogram technique, in particular, with respect to structured Pc 1--2 emissions. This results in the conclusion that the frequency modulation evident in Pearl pulsations is not continuous, but is comprised of waves localized in both time and space whose overall structure produces the stripe-like patterns. Utilizing information from the Multi-Resolution Analysis in conjunction with traditional spectrogram techniques this paper is the first to show clear signal power relationships between Pc 1--2 and Pc3 waves and also between Pc 1--2 and Pc 5 waves as detected on …

In-Situ Study Of The Influence Of Additives On The Growth Behavior Of Copper Electrodeposits On Copper Single Crystal, Aiwen Wu

Doctoral Dissertations

Trace organic additives are known to be essential in obtaining desired metal electrodeposits in the microelectronic industry, however, fundamental design principles for their use and a scientific understanding of their interaction during electrodeposition is lacking. In the present study we investigated electrodeposition of copper on the Cu(100) surface in air-saturated or dearated acid-sulfate plating solutions containing several combinations of chloride and additives benzotriazole (BTA) and 3-mercapto propane sulfonic acid (MPSA) under galvanostatic pulse-current conditions. The electrodeposition process was followed using in-situ atomic force microscopy (AFM). AFM images were quantitatively analyzed by pattern-recognition and scaling procedures.

In the absence of additives, …

A Wavelet-Based Cmac For Enhanced Multidimensional Learning, Brian P. Kirk

Doctoral Dissertations

The CMAC (Cerebellar Model Articulation Controller) neural network has been successfully used in control systems and other applications for many years. The network structure is modular and associative, allowing for rapid learning convergence with an ease of implementation in either hardware or software. The rate of convergence of the network is determined largely by the choice of the receptive field shape and the generalization parameter. This research contains a rigorous analysis of the rate of convergence with the standard CMAC, as well as the rate of convergence of networks using other receptive field shape. The effects of decimation from state-space …

Bedrock Geology Of The Seacoast Region Of New Hampshire, United States, Jose Cruz Escamilla-Casas

Doctoral Dissertations

The seacoast region of New Hampshire is underlain by two lithotectonic belts: the Rye Complex (RC), and the eastern portion of the Merrimack Group (MG). The Rye Formation and the Breakfast Hill member constitute the RC; the Kittery, Eliot, and Berwick Formations, the MG. The stratigraphic order interpreted in this study places the Kittery Formation transitionally above the Eliot, and identifies the contact between the Berwick and the Eliot Formations as a fault.

Study of folds using a variant of the Fourier series analysis indicates that the degree of asymmetry and shape of folds in the MG and the RC …

The Central New England Sea Breeze Study, Samuel T K Miller

Doctoral Dissertations

The synoptic and mesoscale environments conducive to the formation of sea breezes were examined, as well as the spatial and temporal evolution of sea-breeze circulations, gravity currents, and fronts along the central New England coast. Sea breeze events were defined as occurring when the observed surface wind direction began the day outside the southeast quadrant, shifted to southeast by afternoon, then shifted back out of the southeast quadrant in the evening, driven by mesoscale, insolation-induced cross-shore temperature gradients.

The meso-alpha (200--2000 km) sea-breeze forcing in the study area was defined as a combination of the cross-shore potential temperature gradient (deltatheta/deltax) …

The Knowledge Survey: A Tool For All Reasons, Edward Nuhfer, Delores Knipp

To Improve the Academy: A Journal of Educational Development

Knowledge surveys provide a means to assess changes in specific content learning and intellectual development. More important, they promote student learning by improving course organization and planning. For instructors, the tool establishes a high degree of instructional alignment, and, if properly used, can ensure employment of all seven best practices during the enactment of the course. Beyond increasing success of individual courses, knowledge surveys inform curriculum development to better achieve, improve, and document program success.

Negotiating The Jurisprudential Terrain: A Model Theoretic Approach To Legal Theory, Christopher Roederer

Seattle University Law Review

This paper explores borrowing a meta-theoretical approach to theory from the natural and social sciences in order to provide a framework within which to situate and evaluate the various theories one encounters in the field of law and jurisprudence. Often it is the case that students of jurisprudence go from one school or theory to another with one of three responses: (1) this makes no sense to me; (2) this makes some sense, but what is the point or relevance; or (3) this makes sense and seems true, but so do many of the schools, theories, and theorists we have …
