A Vision For Administering An Elementary School, Karen L. Thorpe

Graduate Research Papers

My philosophy of educational leadership has developed from the experiences I have had over the course of my lifetime. It began with the values taught to me by my parents and has continued to build to the present. My parents provided a caring and secure family life for my four siblings and me. Neither my mother nor my father had the benefit of much formal education. Neither was able to graduate from high school because they had the obligation to contribute income to their families during the depression. Perhaps the hardships they lived through were the basis of the values …

Morphology Predicts Suction Feeding Performance In Centrarchid Fishes, Andrew M. Carroll, Peter C. Wainwright, Stephen H. Huskey, David C. Collar, Ralph G. Turingan

Ocean Engineering and Marine Sciences Faculty Publications

Suction feeding fish differ in their capacity to generate subambient pressure while feeding, and these differences appear to relate to morphological variation. We developed a morphological model of force transmission in the fish head and parameterized it with measurements from individual fish. The model was applied to 45 individuals from five species of centrarchid fishes: Lepomis macrochirus, Lepomis punctatus, Lepomis microlophus, Micropterus salmoides and Pomoxis nigromaculatus. Measurements of epaxial cross-sectional area, epaxial moment arm, buccal area and buccal area moment arm were combined to estimate pressure generation capacity for individual fish. This estimation was correlated with pressure measured in fish …

A Defense Of The Causal Efficacy Of Dispositions, Jennifer Mckitrick

Department of Philosophy: Faculty Publications

Disposition terms, such as 'cowardice,' 'fragility' and 'reactivity,' often appear in explanations. Sometimes we explain why a man ran away by saying that he was cowardly, or we explain why something broke by saying it was fragile. Scientific explanations of certain phenomena feature dispositional properties like instability, reactivity, and conductivity. And these look like causal explanations - they seem to provide information about the causal history of various events.

Philosophers such as Ned Block, Jaegwon Kim, Elizabeth Prior, Robert Pargetter, and Frank Jacksonl have suggested reasons for thinking that dispositions are causally inert. I call this the "Inert Dispositions View." …

Modification Of Growing-Season Surface Temperature Records In The Northern Great Plains Due To Land-Use Transformation: Verification Of Modelling Results And Implication For Global Climate Change, Rezaul Mamood, Kenneth G. Hubbard, Christy Carlson

School of Natural Resources: Faculty Publications

Land-use and land-cover change can modify near-surface atmospheric condition. Mesoscale modelling studies have shown that modification in land use affects near-surface soil moisture storage and energy balance. Such a study in the Great Plains showed that changes in land use from natural grass to irrigated agriculture enhanced soil water storage in the root zone and increased latent energy flux. This increase in latent energy flux would correspond to a decrease in sensible heat flux and, therefore, modify near-surface temperature records. To verify this deduction, we have investigated the changes in the historical near-surface temperature records in Nebraska, USA. We have …

Discrimination Against And Adaptation Of Italians In The Coal Counties Of Oklahoma, David G. Loconto

Great Plains Quarterly (through 2013)

In the late 1800s and early 1900s coal reigned supreme in what is now southeastern Oklahoma. As was the case in the northeastern United States, Italians and other immigrants from southern and eastern Europe were brought in as a form of inexpensive labor to work the mines. Italians had different customs, a different language, a unique appearance, and a lack of training in mining compared with the American, English, Irish, and Scottish miners that preceded them. These differences were the foundation of an atmosphere in which immigrant groups would settle in communities. The results were struggles between southern and eastern …

Book Review: Gone: Photographs Of Abandonment On The High Plains, David Taylor

Great Plains Quarterly (through 2013)

Steve Fitch's photographs depicting the interior of abandoned houses, schools, and stores on the High Plains are struck though with melancholy. Not the self-absorbed and self-pitying brand, but that of an observer who has come upon something tragic - lost potential, displaced lives, failed communities.

Refining Rural Spaces: Women And Vernacular Gentility In The Great Plains, 1880-1920, Andrea G. Radke

Great Plains Quarterly (through 2013)

In 1887 the Plains photographer Solomon Butcher met the David Hilton family in Custer County, Nebraska. Mrs. Hilton desired a photograph to send to relatives back East, but felt embarrassed by the family's sod dwelling. She insisted that Butcher not take a photo of the house, but asked the men to drag the Hiltons' beautiful new pump organ out into the field, where the family could pose around the instrument. The sod house remained outside the photograph, and after the session the men returned the organ to the house. To Mrs. Hilton, the organ became her personal symbol of aspirations …

Resource Allocation In A Breeding Program For Phosphorus Concentration In Maize Grain, Brandon M. Wardyn, W. Ken Russell

Department of Agronomy and Horticulture: Faculty Publications

When beef cattle (Bos taurus) are fed grain of maize (Zea mays L.) in which the concentration of phosphorus (P) exceeds the animal’s need for this element, the excess P is excreted in the feces. Spreading this manure on cropland increases the potential for P pollution of surface waters by run-off. Experiments were undertaken to determine the relative magnitudes of genotypic and nongenotypic variances of P concentration in maize grain (P-Gr) to assess the ability to select maize genotypes in which this trait more closely matches the dietary need of beef cattle. Genetic variability was found in …

Windbreaks In North American Agricultural Systems, James R. Brandle, Laurie Hodges, Xinhua H. Zhou

Department of Agronomy and Horticulture: Faculty Publications

Windbreaks are a major component of successful agricultural systems throughout the world. The focus of this chapter is on temperate-zone, commercial, agricultural systems in North America, where windbreaks contribute to both producer profitability and environmental quality by increasing crop production while simultaneously reducing the level of off-farm inputs. They help control erosion and blowing snow, improve animal health and survival under winter conditions, reduce energy consumption of the farmstead unit, and enhance habitat diversity, providing refuges for predatory birds and insects. On a larger landscape scale windbreaks provide habitat for various types of wildlife and have the potential to contribute …

Glyphosate Efficacy On Velvetleaf Varies With Application Time Of Day, Aaron L. Waltz, Alex R. Martin, Fred W. Roeth, John L. Lindquist

Department of Agronomy and Horticulture: Faculty Publications

Field and growth chamber experiments determined the efficacy of temporal glyphosate applications on velvetleaf. Glyphosate was applied post-emergence to velvetleaf periodically before and during light and after dark. In 1999, glyphosate at 840 g ae/ha applied before sunrise and after midday provided 54 and 100% velvetleaf control, respectively. In 2000, glyphosate at 840 g/ha applied before sunrise, midday, and after sunset provided 69, 100, and 37% velvetleaf control, respectively. In the growth chamber, glyphosate at 840 g/ha applied before or after light reduced velvetleaf biomass 15 to 20% or 32 to 47%, respectively, and reduced velvetleaf height 24% or 45 …

Utilizing Arts-Related Activities In Accordance With Multiple Intelligence Theories To Increase Third Grade Gifted And Talented Students’ Interest In Language Arts Instruction, Kevin Kovacs

Abraham S. Fischler College of Education ETD Archive

This applied dissertation was designed to investigate the effects of arts-related activities on the interest levels and achievement of third grade gifted students. An important consideration for the improvement of gifted education is the necessity for educators to understand the nature and needs of the gifted learner, including their uneven social and emotional development. In spite of the gifted and talented child’s advanced intellectual development, an asynchronous social and emotional development may sometimes result in lower than expected academic performance. The discrepancy between a high measure of intelligence and low levels of academic achievement may be due to common characteristics …

Measuring The Robustness Of A Resource Allocation, Shoukat Ali, A. A. Maciejewski, Howard Jay Siegel, Jong-Kook Kim

Electrical and Computer Engineering Faculty Research & Creative Works

Parallel and distributed systems may operate in an environment that undergoes unpredictable changes causing certain system performance features to degrade. Such systems need robustness to guarantee limited degradation despite fluctuations in the behavior of its component parts or environment. This research investigates the robustness of an allocation of resources to tasks in parallel and distributed systems. The main contributions are 1) a mathematical description of a metric for the robustness of a resource allocation with respect to desired system performance features against multiple perturbations in multiple system and environmental conditions, and 2) a procedure for deriving a robustness metric for …

Using Multi-Spectral Imagery To Evaluate Corn Grown Under Nitrogen And Drought Stressed Conditions, Shannon L. Osborne, James S. Schepers, Mike R. Schlemmer

Department of Agronomy and Horticulture: Faculty Publications

The in-season estimation of crop stresses which have the potential of adversely affecting crop yield and/or quality could allow producers to make in-season management decisions to correct for the particular stress. A field study was conducted to evaluate the use of multispectral imagery for estimating corn (Zea mays L.) grain yield, in-season biomass and nitrogen (N) concentration under varying N and drought stresses. The experiment was a split-plot design with three replications using a factorial arrangement of treatments. Three irrigation (whole-plot) treatments included dry land, irrigation based on 0.5, and full evapotranspiration (ET). Sub-plot treatments included five N …

Stationkeeping Of An L₂ Libration Point Satellite With Θ-D Technique, Ming Xin, S. N. Balakrishnan, Henry J. Pernicka, Michael W. Dancer

Mechanical and Aerospace Engineering Faculty Research & Creative Works

A new method for L₂ libration-point orbit stationkeeping is proposed in this paper using continuous thrust. The circular restricted three-body problem with Sun and Earth as the two primaries is considered. The unstable orbit about the L₂ libration-point requires stationkeeping maneuvers to maintain the nominal path. In this study, an approach, called the "θ-D technique," based on optimal control theory gives a closed-form suboptimal feedback solution to solve this nonlinear control problem. In this approach the Hamiltonian-Jacobi-Bellman (HJB) equation is solved approximately by adding some perturbations to the cost function. The controller is designed such that the actual …

Accuracy And Interferences For Enzyme-Linked Immunoassay Tests For Atrazine, Craig D. Adams, Hua Jiang, Michael Mcguire, Nicole Graziano, Alan Roberson, Michelle Frey

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Atrazine is one of the most commonly used herbicides in the United States, therefore it is a regulatory concern and is extensively monitored in the environment, especially in drinking water. Because of the higher costs of gas chromatography (GC) methods, utility managers and regulators are considering the increased use of enzyme-linked immunosorbent assay (ELISA) methods for monitoring atrazine. an ELISA test kit was recently approved by the US Environmental Protection Agency. the research in this article points out potential biases and inaccuracies that may occur with such test kits. ELISA test kits for atrazine are typically precise (repeatable) but often …
