The pragmatic approach of Roger von Oech forms the basis for a selection of strategies useful for unlocking and encouraging creative thinking in the 4-8 classroom.

Homography Based Multiple Camera Detection Of Camouflaged Targets, Jesus Flores Guerra

Open Access Theses & Dissertations

This Thesis proposes an improvement on segmentation of camouflaged objects by combining information from multiple static cameras with overlapping views onto a common reference plane. Previous camouflage detection work relies on a single camera and focuses on pattern recognition, gray level co-occurrence matrix (GLCM) computation, convexity detection and operations such as connected components or morphology. These methods make real-time implementation computationally expensive. The proposed work diverges from these techniques, taking advantage of the added information from several viewpoints. Background subtraction is performed on each individual camera and then, the segmentation result is transformed onto a common plane using homography. A …

Evaluation Of An Image Processing Algorithm For Scene Change Detection, Daniel Flores

Open Access Theses & Dissertations

Despite the efforts to reduce traffic accidents by government entities and automobile manufactures, the numbers of accidents are not considerably reduced. An evaluation of an algorithm based on the fly's eye is done on this research applying its principles to detect scene change on images for printed circuit boards providing initial steps to implement this algorithm on vehicular traffic to keep track of objects moving on the field for collision avoidance purposes. The effectiveness of the algorithm is addressed through a comparison of its performance with that found in experimental data.

Quantifying Anisotropy In Asphalt Concrete Pavements Using An Ultrasonic Method, Monica C. Jurado

Open Access Theses & Dissertations

Asphalt concrete is a bonded granular material whose internal structure is anisotropic. Such anisotropy is due to anisotropic particles and void's structure, particle distribution and orientation, and restrain and force pattern used during compaction. Even with this knowledge asphalt concrete design is made considering asphalt concrete as an isotropic material. The biggest difference between an isotropic and anisotropic material is that, an isotropic material is characterized by two independent constants and an anisotropic material could be characterized by up to 81 constants. An extensive research to characterize and quantify anisotropy is only available for some composite materials. Based on the …

A Multi-Tracer Study Of Saltwater Origin, Cross-Formational Flow, And The Geochemical Evolution Of Groundwater In The Southern High Plains Aquifer Along The Western Caprock Escarpment, East-Central New Mexico, Jeff Langman

Open Access Theses & Dissertations

Sustainable management of groundwater resources requires sufficient knowledge of the distribution of fresh and saline groundwater and the processes affecting saltwater intrusion that may influence the beneficial use of groundwater. A hydrogeologic investigation that coupled various chemical and isotopic tracers, including 3H/3He, 14C, δD, δ18O, 87Sr/86Sr, and δ11B, with the physical characteristics of the aquifer was conducted to determine source waters, the origin of saltwater and its influence through cross-formational flow, and water-rock interactions in the Southern High Plains aquifer along the Western Caprock Escarpment. Sub-aquifers or local flow systems are present along the Western Caprock Escarpment, and the study …

Motherhood:Portrayals In American Literature, Christine J. O'Leary

Open Access Theses & Dissertations

ABSTRACT

The purpose of this Thesis is to illustrate five categories of motherhood in American literature. The five categories chosen are: the self-absorbed mother, the self-martyred mother, the child-sacrificing mother, the self-sacrificing mother, and the substitute mother. I chose these five categories because they appear frequently in texts written by people of multiple ethnicities who represent several larger American cultures.

1. The self-absorbed mother lives for her personal pleasures. Her children are a burden. She prefers her happiness over the day to day care of the children.

2. The self-martyred mother believes that she is responsible for all the difficulties …

Assessment Of Human Muscle Fatigue From Surface Emg Signals Recorded During Isometric Voluntary Contractions By Using A Cosine Modulated Filter Bank, Cristhian Mauricio Potes

Open Access Theses & Dissertations

Human muscle fatigue involves both a decrease in the frequency and increase in the amplitude of a surface electromyographic (EMG) signal. Muscle fatigue is also related to a decrease of the force impeding to reach the same initial level of the maximum voluntary contraction (MVC). To determine muscle fatigue indices, a method is proposed by decomposing a surface EMG signal into 32-subbands. This decomposition was attained by using a cosine modulated filter bank. The

surface EMG signals analyzed during this research were recorded during isometric voluntary contractions. Both the instantaneous mean frequency (IMF) and the instantaneous amplitude (IA) are estimated …

The N400 Erp: Semantic Vs. Evaluative Incongruities, Jennifer Hilda Taylor

Open Access Theses & Dissertations

The objective of this research was to utilize both behavioral (response times) and psychophysiological measures (ERPs - N400 & Pre-response Positivity) to uncover the cognitive mechanism responsible for the evaluative priming effect (spreading activation vs. response competition) by controlling for semantic influences. This research project examined the evaluative incongruity effect by controlling for semantic influences in two separate studies. The first study kept semantic associations among word pairs completely random, while the second study controlled for semantic associations by either pairing words from the same semantic category (e.g., animal-animal) or from different semantic categories (e.g., animal-person). Participants completed an evaluative …

Prosecutorial Perseveration: A Reaction To Public Commitment?, Elizabeth Rose Uhl

Open Access Theses & Dissertations

The startling number of cases in which prosecutors ignore clear-cut exculpatory evidence and persist in the prosecution of an almost certainly innocent suspect may be related to the public nature of these prosecutors' commitments. Research has shown that people who make a public commitment to a decision are more likely to stick with their decision in the face of contrary evidence than people who did not make a public commitment. This study examined the effects of public commitment on undergraduate mock prosecutors' decisions to prosecute in a fictional murder case. Half of the participants rendered an initial decision which was …

Giardia Lamblia: Genomic And Molecular Analyses Of Flippase, Diana Leticia Villazana-Kretzer

Open Access Theses & Dissertations

Giardia lamblia, is an intestinal protozoan parasite responsible as a major cause of water-borne intestinal infection in humans (giardiasis). It has been proposed earlier that Giardia has limited lipid synThesis ability and therefore relies on preformed lipid molecules from outside sources. It has also been proposed that lipids are taken up through passive and active transport, and giardial flippasse play a significant role in this process. This study describes the identification and characterization of a putative homologue of flippase gene from Giardia. Flippase is an enzyme that functions as a trans-bilayer transport system facilitating the flip flop diffusion of phospholipids …

Quality Evaluation Of Portland Cement Concrete At Early Age With Free-Free Resonant Column, Gilberto Wenglas

Open Access Theses & Dissertations

At early age, the behavior and mechanical properties of portland cement concrete changes rapidly with time due to hydration. The hydration process consists of a series of chemical reactions that accelerate nonlinearly with the rise in temperature. The hydration process consists of three stages: the dormant period, the setting time, and the hardening time. Timely opening of roads and resumption of constructions depend of the knowledge of these stages. The initial and final setting times are arbitrarily determined by a standard test (ASTM C 403). Although the setting time has been studied for many decades, the new technologies allow making …

Expert System Design Guide For Lower Classification Roads Over High Pi Clays, Yaqi Wanyan

Open Access Theses & Dissertations

This research was focused on low-volume roads over expansive clayey soils in Texas. In spite of the redundant pavement designs recommended and widely used in Texas for roads in high PI clay areas, these pavements often fail prematurely. This failure occurs primarily because of the highly variable properties of the clayey subgrade throughout the year due to moisture fluctuations. The problematic nature of high PI clays, despite the fact that volumetric changes such as heaving are sometime considered in the design, is of concern since they contribute to roughness and longitudinal shrinkage cracking of the road, and as such the …

The Application Of Federal And Texas State Sentence Ranges In A, Jessica Leigh Wildermuth

Open Access Theses & Dissertations

Sentencing decisions are usually made in situations of judgmental uncertainty because they are typically complex and make use of inherently ambiguous information (Saks & Kidd, 1980). Research on underlying judgment processes has demonstrated that anchors provide a basis for simplifying judgments that involve uncertainty (Higgins, 1996; Tversky & Kahneman, 1974). To investigate sentencing disparities that occur for identical crimes, it is also essential to understand the psychological mechanisms that underlie decision making. The Selective Accessibility Model (Tversky & Kahneman, 1974) states that, "people construct a mental mode that selectively increases the accessibility of anchor-consistent information" (p.1125). In turn,because this information …

Evaluation Of A Nutrition Program Targeting Child Care Centers, Kendra Witt

Open Access Theses & Dissertations

Color Me Healthy (CMH) is an interactive nutrition program designed for preschool aged children in child care settings. The current study examined if CMH increases the consumption of fruit and vegetables. Child care centers were randomly assigned to one of two conditions; children (n=165) in ten centers received CMH and children (n=98) in seven centers acted as controls. Consumption of fruit and vegetable snacks was assessed at baseline, one week post-intervention and 3 months post-intervention. Hierarchical linear modeling determined that group assignment was the only significant predictor of fruit and vegetable consumption. Children who were exposed to the CMH program …

Remixing Obviousness, Joseph S. Miller

Scholarly Works

In April 2007, the Supreme Court, for the first time in 41 years, decided a case about the basic contours of patent law's nonobviousness standard. The case, KSR, upends 25 years of Federal Circuit jurisprudence, and on a legal requirement that every patent must satisfy. In this essay, I show how KSR dismantles two predicates that have long shaped Federal Circuit nonobviousness cases - namely, the intertwined premises that hindsight-driven distortion is the gravest risk to an accurate nonobviousness requirement, and that the person of ordinary skill in the art (from whose perspective nonobviousness is judge) is singularly uncreative. In …

"I'M Sorry, I Can't Answer That": Supreme Court Confirmations, Judicial Independence, And Positive Legal Scholarship, Lori A. Ringhand

Scholarly Works

The United States Constitution grants to the Senate the duty to provide its “advice and consent” to the appointment of Supreme Court Justices. Just how senators should exercise that duty, however, is deeply contested. Much of the dispute about the Senate's role involves the appropriate scope of questions the senators should ask, and what nominees should be expected to answer, at the confirmation hearing held by the Senate Judiciary Committee. Opponents of vigorous senatorial questioning argue that such questioning infringes on the independence of the judiciary; proponents argue that the nominees' failure to answer probing questions hinders the Senate's constitutional …

The Honest Broker? Canada's Role In Haitian Development, Michele Zebich-Knos

Faculty Articles

Since the early 1990s Canada has played a key role in Haiti’s development process. The article explores whether Canada’s foreign policy is becoming more reliant on military-assisted solutions, including peacekeeping, as a way to solve Haiti’s internal problems and achieve good governance. The article also examines the Canadian concepts called “Responsibility to Protect, React and Rebuild” which are linked to humanitarian intervention, and their implication for Haitian sovereignty. The conclusion cautions against an overly ambitious Canadian development policy for Haiti which has little chance of success.

Making The Law: Unpublication In The District Courts, Hillel Y. Levin

Scholarly Works

In recent years, one particular area of focus for legal scholars concerned about the increasing privatization and opacity of courts has been the issue of systematic unpublication of judicial opinions by the appellate courts. Judges have issued dueling opinions on the constitutionality of the practice and traded polemics on its appropriateness. Practitioners – whose voices often seem lost (or at least muted) on issues like this – are in the thick of the debate. No longer merely academic, this debate has even spawned a change in the rules of appellate procedure (one that amusingly pulled off the difficult feat of …

Environmental Law, Eleventh Circuit Survey, Travis M. Trimble

Scholarly Works

In 2007 the Eleventh Circuit interpreted the United States Supreme Court’s decision in Rapanos v. United States, regarding the federal government’s jurisdiction over waters under the Clean Water Act (“CWA”), and held that in order for federal jurisdiction to exist over a water that is not navigable in fact, the water must have a “significant nexus” with a water that is navigable in fact. Also under the CWA, the court partially reversed a granting of summary judgment to the Florida Department of Environmental Protection, holding that the department had improperly excluded some types of evidence in approving Florida’s 2002 …

Christian Publishing: A Panel Discussion, Dennis Hillman, Mark Hunt, Jim Kinney, Jon Pott, Gregory A. Smith

The Christian Librarian

The 2007 conference of the Association of Christian Librarians convened in Grand Rapids, Michigan, on the campus of Cornerstone University. Conference planners invited representatives of four prominent Christian publishers headquartered there (Baker, Eerdmans, Kregel, and Zondervan) to participate in a panel discussion on June 13. The panelists’ 65-minute exchange is transcribed here in slightly abbreviated form. At the beginning of the discussion, panelists were asked to reflect on general trends in the Christian publishing industry. This led naturally to a lengthy conversation about the publishers’ involvement in the creation and licensing of ebooks and other digital products. Finally, panelists were …

Hidden Under A Bushel? Evangelical Journals In An Era Of Web-Based Communications, Gregory A. Smith

The Christian Librarian

Evangelicals face significant obstacles as they seek to make their publications accessible to potential readers. This study measures the extent to which evangelical scholarly journals have made their contents available in electronic form. Thirty-five journals – all active, refereed, evangelical in perspective, and published in English – were chosen for analysis. Two serials management tools and individual journal Web sites provided data regarding electronic accessibility. Twenty-six of the journals are available in some electronic form – most commonly in one or more aggregated databases. Evangelical information professionals could play a significant role in helping to make additional evangelical journal content …

Biological Control Of Fusarium Oxysporum Wilt Disease Of Tomato By Antagonistic And Plant Growth Promoting Actinomycetes, Nada Mohammed Ibrahim Al-Shugairan

Theses

Soil-borne fungal plant pathogens cause some of the most widespread and serious plant diseases. Root diseases caused by these pathogens such as wilt, root rot, collar rot, foot rot, seedling pre- and post-emergence damping-off are the foremost of problems which are gaining importance from day to day in the world and for which no direct control measures have been evolved so far. Fusarium spp. is a widespread soil-borne plant pathogen and is the causal agents of wilt disease of many economically important crops. Fusarium spp. is a limiting factor in the plant productivity in most agricultural soils. Wilt disease of …

The Federal Marriage Amendment And The False Promise Of Originalism, Thomas Colby

GW Law Faculty Publications & Other Works

This Article approaches the originalism debate from a new angle - through the lens of the recently defeated Federal Marriage Amendment. There was profound and very public disagreement about the meaning of the FMA - in particular about the effect that it would have had on civil unions. The inescapable conclusion is that there was no original public meaning of the FMA with respect to the civil unions question. This suggests that often the problem with originalism is not just that the original public meaning of centuries-old provisions of the Constitution is hard to find (especially by judges untrained in …

Quanta V. Lg Electronics: Frustrating Patent Deals By Taking Contracting Options Off The Table?, F. Scott Kieff

GW Law Faculty Publications & Other Works

The Supreme Court's unanimous decision in Quanta v. LG Electronics may make it significantly more difficult to structure transactions involving patents. While this decision does make a group of players into winners in the immediate term for existing patent deals (this group includes any customer who, like Quanta, buys patented parts without buying a patent license), almost everyone is likely to come out a loser going forward.

The Court in Quanta decided that a patent license that LG Electronics sold only to Intel - and explicitly limited to exclude Intel's customers, like Quanta, and priced to reflect these modest ambitions …

The Gay Panic Defense, Cynthia Lee

GW Law Faculty Publications & Other Works

In this article, I examine the use of gay panic defense strategies in the criminal courtroom. I argue that such strategies are problematic because they reinforce and promote negative stereotypes about gay men as sexual deviants and sexual predators. Gay panic defense strategies are also troubling because they seek to capitalize on unconscious bias in favor of heterosexuality which is prevalent in today's heterocentric society. Most critics of the gay panic defense have proposed that judges or legislatures should bar gay panic arguments from the criminal courtroom. I take a contrary position and argue that banning gay panic arguments from …

Maximizing Special Education Teacher Retention: Teacher's Perceptions Of Administrative Support In Pre K-12 Public Schools As Implications For Improvement, Dawn R. Showers

Electronic Theses and Dissertations

The purpose of this study was to explore the perceptions of special education teachers regarding administrative support provided by their building principals as related to teacher retention, gender, and disability category taught. Research over the course of the past decade indicates that teachers are more likely to leave the teaching profession when they fail to receive an adequate amount of administrative support. A survey questionnaire was used to collect 125 responses from special education teachers working in South Central Pennsylvania public schools. The population sample consisted of teachers from four special education teacher certification categories including classroom and itinerant staff. …
