Qr Factorization With Morton-Ordered Quadtree Matrices For Memory Re-Use And Parallelism, Jeremy D. Frens, David S. Wise

University Faculty Publications and Creative Works

Quadtree matrices using Morton-order storage provide natural blocking on every level of a memory hierarchy. Writing the natural recursive algorithms to take advantage of this blocking results in code that honors the memory hierarchy without the need for transforming the code. Furthermore, the divide-and-conquer algorithm breaks problems down into independent computations. These independent computations can be dispatched in parallel for straight-forward parallel processing. Proof-of-concept is given by an algorithm for QR factorization based on Givens rotations for quadtree matrices in Morton-order storage. The algorithms deliver positive results, competing with and even beating the LAPACK equivalent.

A Case For Changing The National Airspace System From A Magnetic North To A Geographic North Based Model, Michael K. Larson

Journal of Aviation/Aerospace Education & Research

The Global Positioning System (GPS) is currently playing a major role in aviation navigation and is proposed by the Federal Aviation Administration (FAA) to be the foundation of the future National Airspace System (NAS). The Position, Velocity and Time (PVT) information provided by GPS for navigation purposes is directly based on Geographic North parameters rather than on Magnetic North, which is currently the foundation of the NAS. This paper uniquely addresses the exploration of this relationship between the GPS and Geographic North by applying an experimental research design to analyze the potential benefit of basing the NAS on Geographic North. …

Avid: A Comprehensive School Reform Model For Texas, Karen M. Watt, Darlene Yanez, Griselda Cossio

Organization and School Leadership Faculty Publications

The implementation of a recent comprehensive school reform effort in the state of Texas bas been examined in this article. The effort, Advancement Via Individual Determination (AVID), was studied in-depth over the two-year implementation period through school visits, observations, stakeholder interviews, and student performance data analysis. Main findings revealed that through proper implementation (strong instructional leadership, using AVID strategies school-wide, and staff development), underachieving, economically disadvantaged, ethnic minority students can succeed in a rigorous curriculum. AVID is a catalyst for school-wide reform; AVID addresses and influences school policies that can be barriers to student success; AVID is a pathway to …

The Contribution Of Education, Experience, And Personal Characteristics On The Reflective Judgment Of Students Preparing For School Administration, Margaret Rae Macdonald

Dissertations

Problem. School administrators must use high levels of reasoning to deal with the complexities of today's educational system. Reflective thinking has proven to be an effective administrative tool in problem solving, staff supervision, and school improvement, yet preparation programs for school administrators have limited knowledge about what contributes to reflective judgment in their students, thus making it difficult to develop curriculum and pedagogy to enhance reflection.

Method. The Reflective Judgment Model provides the theoretical framework for this mixed methods research design that explores contributory variables that contribute to the reflective judgment of educational leadership students. The Reasoning about Current …

The Effects Of Cooperative Learning Versus Traditional Classroom Instruction On Cognitive Achievement, Critical Thinking, And Attitudes Toward Learning In Teams In A Physician Assistant Program, Scott L. Massey

Dissertations

Problem. Physician assistants are required to possess critical thinking skills and excellent intellectual skills to achieve the level of autonomy expected by supervising physicians. No scientific research has been identified to determine the most effective means of educating the physician assistant students. The purpose of the research study was to determine whether a statistical difference exists between students educated in a cooperative learning environment versus a traditional lecture environment. The dependent variable utilized in this study included critical thinking skills, cognitive achievement, and attitudes towards learning in teams. Using an experimental research design, students were educated in a cooperative learning …

Intention To Pursue Post-Secondary Education, And Related Factors, Among Jamaican Senior High School Students, Teran T. Milford

Dissertations

Purpose of the Study. The proportion of female students in post-secondary schools in Jamaica is approximately twice that of their male counterpart. This is in contrast to the observation that the proportion of male and female students in elementary and secondary schools is about the same. Little or no studies have been conducted to examine factors related to the disproportion of male and female students in tertiary institutions. Therefore, the purpose of this study was to examine the perception of senior high school students regarding their intention to pursue post-secondary education, and to determine the extent to which the value …

Perceptions Of Problem-Based Learning And Attitudes Towards Its Adoption Among K-12 Teachers In Seventh-Day Adventist Schools In Florida, Eileen A. Pilliner

Dissertations

Problem

One of the founders of Seventh-day Adventist education, Ellen G. White, advocated learning through, practical experiences and critical thinking. In 1997, the Seventh-day Adventist Church recommended problem-based learning (PBL) as a preferred teaching practice for its North American K-12 schools. However, Brantley and Ruiz observed that many Seventh-day Adventist educators feel inadequate to use this method of instruction. Little information exists anywhere concerning teachers’ awareness and perceptions o f problem-based learning (PBL) or factors related to its use. This study examined the relationship between PBL, philosophy of teaching, preferences for PBL teaching components, and perceived barriers to PBL adoption …

The Impact Of Early-Intervention/Prevention Services On The Northville Public Schools, Robert O. Sornson

Dissertations

Problem

Whereas some school districts have continued to observe high rates of reading failure and increasing rates of special education identification, others have looked at program or system changes to reduce early learning failure. This study is an analysis of the impact of early intervention practices in the elementary schools of an upper-middle-class community.

Method

Cost analyses of district programs were compared to a hypothetical district with state average levels of special education identification. Special Education eligibility rates were tracked over a 10-year period. Data were collected from surveys given to Instructional-Support Team personnel, general education teachers, elementary administrators, and …

A Study Of The Influence Of Birth Order And Other Variables On Student Perceptions Of School Effectiveness In A Southwestern Michigan County, Hamil Tobias

Dissertations

Problem. There is an increasing demand for quality education. In his initiative for education reform, U.S. President George W. Bush promoted the concept of no child left behind, in which he calls for more accountability. It is useful to examine student perceptions of how well the education system functions. Instead of a monolithic view, their perceptions were analyzed by birth order, gender, and ethnicity. The purpose of this study was to determine to what extent student perceptions differed by their birth order, gender, and ethnicity.

Method. This study utilized a 4 x 2 x 2 (birth order by …

Denying Human Homogeneity: Eugenics & Making Of Post-Classical Economics, Sandra J. Peart, David M. Levy

Jepson School of Leadership Studies articles, book chapters and other publications

The question we propose to address is how did economics move from the classical period characterized by the hardest possible doctrine of initial human homogeneity—all the observed differences among people arise from incentives, luck, and history¹—to become comfortable with accounts of human behavior which alleged foundational differences among and within races of people? (Darity 1995) In this paper, we shall argue that early British eugenics thinkers racialized economics in the post-classical period.²

Establishing Religious Ideas: Evolution, Creationism, And Intelligent Design, Kent Greenawalt

Faculty Scholarship

In this article, I first sketch the basic conflict between evolutionary theory and creationism and describe the opposition of creationists to the teaching of standard evolutionary theory. I then state the basic educational and constitutional questions

about evolution, standard creationism, and "intelligent design." After exploring of five fundamental premises that, in combination, generate the most troubling questions about science, religion, and the public schools, I turn to claims of miracles. Like assertions that God has intervened in natural processes of development, these claims suppose that God transcends or violates scientific principles; their investigation suggests that scientific principles; their investigation suggests …

Aspects Of Conformal Field Theory From Calabi-Yau Arithmetic, Rolf Schimmrigk

Faculty Articles

This paper describes a framework in which techniques from arithmetic algebraic geometry are used to formulate a direct and intrinsic link between the geometry of Calabi-Yau manifolds and aspects of the underlying conformal field theory. As an application the algebraic number field determined by the fusion rules of the conformal field theory is derived from the number theoretic structure of the cohomological Hasse-Weil L-function determined by Artin's congruent zeta function of the algebraic variety. In this context a natural number theoretic characterization arises for the quantum dimensions in this geometrically determined algebraic number field.

Effects Of Range Size On Species–Area Relationships, Andrew P. Allen, Ethan P. White

Biology Faculty Publications

It has been known for some time that the slope of the species–area relationship increases asymptotically at broad spatial scales when richness is plotted against area on logarithmic axes. At continental to global scales, species–area relationships are determined to a large extent by the abundance and size distribution of species ranges. Here we present an analytical model that explicitly quantifies the effects of range size on species–area relationships. The model shows how range size and plot area interact to control the form of species–area relationships at broad spatial scales. It also demonstrates how changes in spatial scale affect biodiversity patterns …

Maintain Hydraulic Control Using Deep Rooted Tree Systems, A. Ferro, M. Gefell, Roger Kjelgren, D. S. Lipson, N. Zollinger, S. Jackson

Plants, Soils, and Climate Faculty Publications

Groundwater phytotechnology systems are currently being used to control the migration of contaminant plumes and remove groundwater that flows into containment areas. Trees in such systems function by reducing recharge and using groundwater via transpiration. A stand of deep-rooted trees can act as a biological "pump", removing a substantial amount of water from the saturated zone. Depth to groundwater compared to rooting depth is an important consideration Many useful tree species are not naturally deep-rooted, but various cultural practices can produce trees with roots that are deep enough to tap into the water table. Hydraulic control can be calculated or …

Thinking Race, Making Nation (Reviewing Glenn C. Loury, The Anatomy Of Racial Inequality), Christopher A. Bracey

GW Law Faculty Publications & Other Works

We live in a race-conscious culture. As Americans, we are a nation of people who self-consciously chose to adopt a vision of society that embraced lofty ideals of individual freedom and democracy for all along with powerful mechanisms for devastating racial oppression. Our history is replete with instances of differential treatment on account of race - slavery being only the most egregious example - that achieved the desired effect of generating remarkable disparities in socioeconomic well-being among individuals and between different racial groups. Such disparities are not simply historical artifacts. They are facts of the contemporary American racial landscape as …

Recognizing Toxic Species In Aquatic Habitats: A Potential Concern In Lake Management, Mikolaj Kokocinski, Harold G. Marshall

Biological Sciences Faculty Publications

The importance of distinguishing toxic and non-toxic algal species is becoming a more common problem for management decisions associated with various freshwater and estuarine habitats. An example is given where two dinoflagellates, originally unidentified as closely resembling the toxin producing Pfiesteria spp., have been compared to these species. In order to clarify any relationship to Pfiesteria spp., scanning electron microscopy was used to determine the plate tabulation patterns of these dinoflagellates and make comparisons to the tabulation present in Pfiesteria spp. The results indicated significant differences in the plate tabulations of these taxa to distinguish them from Pfiesteria …

A Multi-Platform Application Suite For Enhancing South Asian Language Pedagogy, Tao Bai, Christopher K. Chung, Konstantin Läufer, Daisy Rockwell, George K. Thiruvathukal

Computer Science: Faculty Publications and Other Works

This interdisciplinary project explores the potential for handheld/wireless (H/W) technology in the context of language education within and beyond the classroom. Specifically, we have designed and implemented a suite of multi-platform (desktop/laptop, handheld, and browser) applications to enhance the teaching of South Asian languages such as Hindi-Urdu. Such languages are very difficult to learn, let alone write, and H/W devices (with their handwriting/drawing capabilities) can play a significant role in overcoming the learning curve. The initial application suite includes a character/word tracer, a word splitter/joiner, a smart flashcard with audio, contextual augmented stories for reading comprehension, and a poetic metronome. …

Scalable Implementations Of Mpi Atomicity For Concurrent Overlapping I/O, Wei-Keng Liao, Alok Choudhary, Kenin Coloma, George K. Thiruvathukal, Lee Ward, Eric Russell, Neil Pundit

Computer Science: Faculty Publications and Other Works

For concurrent I/O operations, atomicity defines the results in the overlapping file regions simultaneously read/written by requesting processes. Atomicity has been well studied at the file system level, such as POSIX standard. In this paper, we investigate the problems arising from the implementation of MPI atomicity for concurrent overlapping write access and provide a few programming solutions. Since the MPI definition of atomicity differs from the POSIX one, an implementation that simply relies on the POSIX file systems does not guarantee correct MPI semantics. To have a correct implementation of atomic I/O in MPI, we examine the efficiency of three …
