The Role Of Natural And Sexual Selection In The Origin And Maintenance Of Divergence Within And Between The Mexican Sailfin Mollies, Poecilia Velifera And P. Petenensis, Shala Hankison

All Dissertations

Understanding speciation remains a holy grail of evolutionary biology. One useful approach is studying the evolutionary mechanisms important in population divergence to infer the mechanisms important in speciation. This method is especially useful when closely related species can be compared to determine whether intraspecific differences parallel interspecific differences. I studied population divergence in two species of Mexican sailfin mollies, Poecilia velifera and P. petenensis. These closely related species are particularly useful for this type of study, as they live in habitats that may differ in the importance of natural selection. In addition, these species may differ in the importance …

Pilgrimage Narrative: A Pattern For Heavenly Theatre In King Lear, Alexandra Chantal Yvette Mackenzie

Theses and Dissertations

I have always felt personally challenged and invigorated by one line in Peter Brook's canonical text The Empty Stage: “if the need for a true contact with a sacred invisibility through the theatre still exists, then all possible vehicles must be re-examined" (Brook 54). This thesis will endeavour to suggest and explore heavenly theatre, one possible vehicle to find that sacred invisibility. I will argue that heavenly theatre encompasses Peter Brook's understanding of holy theatre, but is more specific and tied to the manifestation of deity in the form of the Holy Spirit as understood and defined within my personal …

Using Duplication With Compare For On-Line Error Detection In Fpga-Based Designs, Daniel L. Mcmurtrey

Theses and Dissertations

Space destined FPGA-based systems must employ redundancy techniques to account for the effects of upsets caused by radiated environments. Error detection techniques can be used to alert external systems to the presence of these upsets. Readback with compare is an error detection technique commonly employed in FPGA-based designs. This work introduces duplication with compare (DWC) as an automated on-line error detection technique that can be used as an alternative to readback with compare. This work also introduces a set of metrics that is used to quantify the effectiveness and coverage of this error detection technique. A tool is presented that …

2d Arbitrary Lagrangian-Eulerian (Ale) Model Of Blood Flow In The Left Ventricle Of The Heart / Zati Hakim Azizul Hasan, Azizul Hasan Zati Hakim

Student Works (2000-2009)

This research is a study of the dynamics of the heart valves and the blood using numerical computational technique. This numerical technique is known as the Arbitrary Lagrangian-Eulerian (ALE) and is introduced in a finite element environment. By means of a mesh movement method, the ALE uses separate sets of reference systems to study the fluid-structure interaction of the heart. The fluid domain is most conveniently described with respect to an Eulerian reference frame while a Lagrangian formulation is more appropriate for the structure domain. Due to the incompatibility factor of the two reference frames, coupling of the reference systems …

Asymmetric Games For Convolution Systems With Applications To Feedback Control Of Constrained Parabolic Equations, Boris S. Mordukhovich

Mathematics Research Reports

The paper is devoted to the study of some classes of feedback control problems for linear parabolic equations subject to hard/pointwise constraints on both Dirichlet boundary controls and state dynamic/output functions in the presence of uncertain perturbations within given regions. The underlying problem under consideration, originally motivated by automatic control of the groundwater regime in irrigation networks, is formalized as a minimax problemof optimal control, where the control strategy is sought as a feedback law. Problems of this type are among the most important in control theory and applications - while most challenging and difficult. Based on the Maximum Principle …

Methods To characterize WTC-related health effects, the WTC Worker and Volunteer Medical Screening Program was established. This multicenter clinical program provides free standardized examinations to responders. Examinations include medical, mental health, and exposure assessment questionnaires; physical examinations; spirometry; and chest X rays. Results Of 9,442 responders examined between July 2002 and …

Tass Mark Iv Photometric Survey Of The Northern Sky, Thomas Droege, Michael Richmond, Michael Sallman, Robert P. Creager

Articles

The Amateur Sky Survey (TASS) is a loose confederation of amateur and professional astronomers. We describe the design and construction of our Mark IV systems, a set of wide-field telescopes with CCD cameras which take simultaneous images in the V and IC passbands. We explain our observational procedures and the pipeline which processes and reduces the images into lists of stellar positions and magnitudes. We have compiled a large database of measurements for stars in the northern celestial hemisphere with V -band magnitudes in the range 7 < V < 13. This paper describes data taken over the four-year period starting November, 2001. One of our results is a catalog of repeated measurements on the Johnson-Cousins system for over 4.3 million stars.

In-School Suspension: A Qualitative Study Of High School Programs, Joseph M. Boone

Graduate Student Dissertations, Theses, Capstones, and Portfolios

In-School Suspension (ISS) is the temporary placement of a student experiencing behavior problems in an alternative location within the school or school district. ISS is designed to offset the negative effects of exclusion and external suspension from school. In the ideal situation students assigned to ISS are under school supervision with an academic component provided (Stiefer, 2003).

There are various forms of ISS including: the punitive format which employs strict rule enforcement, the discussion format which includes activities designed to improve self-esteem, communication, and problem solving skills, and the academic model, which focuses on improving skills required to improve academic …

Importance Of Leadership Competencies And Content For Athletic Training Education And Practice: A Delphi Technique And National Survey, Matthew R. Kutz

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Employers identify leadership as a desirable characteristic of athletic trainers. The Board of Certification's Role Delineation Study advocates "knowledge of leadership styles," and "preparation for leadership roles" should be a "distinguishing characteristic" of post-certification athletic training education. The athletic training literature was weak in identifying leadership competencies or content important for practice or for inclusion in athletic training education programs (ATEPs). A two phase exploratory and comparative research study was conducted using a panel of 18 athletic training experts (Phase One, Modified Delphi Technique, mixed methods) and a randomly selected sample of 161 faculty and athletic training practitioners (Phase Two, …

Landscape Change In The South Prong Alafia River Basin, Kimberly Sarah Koenig

USF Tampa Graduate Theses and Dissertations

West-central Florida has supplied much of the national and global demand for phosphate for over 100 years. The two main tributaries of the Alafia River, the North and South Prongs, have been extensively modified by the strip mining, benefaction, and chemical processing activities associated with the phosphate mining industry. Using aerial photos, an analysis of landscape change in the South Prong Alafia River drainage basin (357.4 km2) between 1940, 1970, and 2004 was conducted. A modified Florida Land Use, Land Cover, and Forms Classification System code (FLUCCS) was used to classify and measure change through the study period. Change in …

The Birth Of Sacrifice: Iconographic Metaphors For Spiritual Rebirth In Master Matthias' Isenheim Altarpiece, Katherine Lena Anderson

Theses and Dissertations

While little is known concerning the events surrounding the commission of the Isenheim Altarpiece or of the artist known to us as Master Matthias Grünewald, much can be ascertained about the message of the Altarpiece through careful study of the socio-historical-religious context from which the work was commissioned and iconographic analysis of the images portrayed by Master Matthias. This thesis explores iconographic metaphors for birth and sacrifice, metaphors which work to create a theological dialogue about Christian redemption within the nine painted panels and the underlying sculpture that makes up the Isenheim Altarpiece. First, we will address the panels in …

An Econometric Analysis Of Determinants Of Foreign Direct Investment: A Panel Data Study For Africa, Evarist Twimukye

All Dissertations

In the last two decades, foreign direct investment has become a major source of investment capital for developing countries. This study evaluates the determinants of foreign direct investment in Africa using fixed effects feasible generalized least squares model for 45 countries covering the period 1990-2003. The study finds gross domestic product, literacy rate, exchange rate and population size to have positive relationship with foreign direct investment. But, inflation rate and remoteness have negative relationship with foreign direct investment. Finally, central, eastern and western regions have lower foreign direct investment than southern region.

Structural Study Of Mn-Doped Zno Fi Lms By Tem, Xingzhong Li, Jun Zhang, David J. Sellmyer

David Sellmyer Publications

The structural study of diluted magnetic semiconductors is important for interpreting the ferromagnetic behavior associated with the materials. In the present work, a series of low concentration Mn-doped ZnO thin films synthesized by pulsed laser deposition was studied by electron microscopy. All films show the wurtzite structure with (001) preferred growth orientation on the Si substrate. Electron diffraction experiments indicate the deterioration of the growth orientation in some areas of the films with increasing Mn concentration, and the existence of a secondary phase, of Mn₂O₃-type, in the films with larger Mn concentrations. High-resolution electron microscopy images …

Collisions Of Red-Tailed Hawks (Buteo Jamaicensis), Turkey Vultures (Cathartes Aura), And Black Vultures (Coragyps Atratus) With Aircraft: Implications For Bird Strike Reduction, Bradley F. Blackwell, Sandra E. Wright

United States Department of Agriculture Wildlife Services: Staff Publications

From 1990 through 2003, 52,493 wildlife collisions with aircraft were reported to the U.S. Federal Aviation Administration (FAA); 97% of these incidents involved birds. The approximate cost to the civil aviation industry in the U.S.A. due to collisions of birds with aircraft (hereafter referred to as bird strikes) was $163.51 million in direct monetary losses and associated costs for the 14 year period (Cleary et al. 2004). Strikes with raptors (Falconidae and Accipitridae; including vultures, Cathartidae)accounted for approximately 28% of reported aircraft down time resulting from known-species bird strikes (known species =182942 hr; total for all birds = 244510 hr) …

Perceptual Or Analytical Processing? Evidence From Children's And Adult's Performance On The Euclidean Traveling Salesperson Problem, Iris Van Rooij, Alissa Schactman, Helena Kadlec, Ulrike Stege

The Journal of Problem Solving

The Euclidean Traveling Salesperson Problem (E-TSP) is a useful task to study how humans optimize when faced with computational intractability. It has been found that humans are capable of finding high-quality solutions for E TSP in a relatively short time and with seemingly little cognitive effort. This observation has led to two general proposals: The high quality of performance on E-TSP reflects (a) the output of automatic and innate perceptual processes or (b) a fundamentally intelligent approach to the task by humans. An experiment was performed to compare performance of three age groups (7- year-olds, 12-year-olds, and adults). Our findings …

A Comparison Of Heuristic And Human Performance On Open Versions Of The Traveling Salesperson Problem, James N. Macgregor, Edward P. Chronicle, Thomas C. Ormerod

The Journal of Problem Solving

We compared the performance of three heuristics with that of subjects on variants of a well-known combinatorial optimization task, the Traveling Salesperson Problem (TSP). The present task consisted of finding the shortest path through an array of points from one side of the array to the other. Like the standard TSP, the task is computationally intractable and, as with the standard TSP, people appear to be able to find good solutions with relative ease. The three heuristics used mechanisms that have been cited as potentially relevant in human performance in the standard task. These were: convex hull, nearest neighbor, and …

Human Performance On Visually Presented Traveling Salesperson Problems With Varying Numbers Of Nodes, Matthew Dry, Michael D. Lee, Douglas Vickers, Peter Hughes

The Journal of Problem Solving

We investigated the properties of the distribution of human solution times for Traveling Salesperson Problems (TSPs) with increasing numbers of nodes. New experimental data are presented that measure solution times for carefully chosen representative problems with 10, 20, . . . 120 nodes. We compared the solution times predicted by the convex hull procedure proposed by MacGregor and Ormerod (1996), the hierarchical approach of Graham, Joshi, and Pizlo (2000), and by five algorithms drawn from the artificial intelligence and operations research literature. The most likely polynomial model for describing the relationship between mean solution time and the size of a …
