Hybrid Matching And Risk Assessment Of The Misspelled Names Hmra, Cihan Varol Dec 2009

Hybrid Matching And Risk Assessment Of The Misspelled Names Hmra, Cihan Varol

Theses and Dissertations

Companies acquire personal information from phone, World Wide Web, or email in order to sell or send an advertisement about their product. However, when this information is acquired, moved, copied or edited, the data may loose its quality. Often, the use of data administrators or a tool that has limited capabilities to correct the mistyped information can cause many problems. Moreover, most of the correction techniques are particularly implemented for the words used in daily conversations. Since personal names have different characteristics compared to general text, firstly, we proposed a hybrid matching algorithm (PNRS) which employs phonetic encoding, string matching …

No Child Left Behind: Perspectives And Knowledge Of Parental Involvement Component Section 1118 Among Administrators And Parents In Elementary Schools, Jill Yvette Brooks Dec 2009

No Child Left Behind: Perspectives And Knowledge Of Parental Involvement Component Section 1118 Among Administrators And Parents In Elementary Schools, Jill Yvette Brooks

Theses and Dissertations

No Child Left Behind (NCLB) requires states, districts, and schools develop and implement parental involvement policies, yet, the extent of implementation remains largely unmeasured (United States Department of Education, 2002). Thus, the researcher surveyed 142 elementary school administrators and 639 parents in a southern state to determine if a statistically significant difference existed between parent and administrator perceptions and practices and current knowledge of parental involvement as outlined in NCLB and whether parental responses differed by demographics. The survey utilized a four-point Likert-type Scale with 12 questions measuring perceptions and practices (Cronbach's alpha = .84) and 8 measuring current knowledge …

Real Time Network Monitoring And Reporting System, Ricky Lee Massengale Sr. Dec 2009

Real Time Network Monitoring And Reporting System, Ricky Lee Massengale Sr.

Theses and Dissertations

With the ability of modern system developers to develop intelligent programs that allows machines to learn, modify and evolve themselves, current trends of reactionary methods to detect and eradicate malicious software code from infected machines is proving to be too costly. Addressing malicious software after an attack is the current methodology and should be a fallback approach. A modern approach should be to perpetually monitor the "enterprise network backbone" traffic and broadcast alerts while taking protective and pre-emptive measures, in the event that the traffic falls out of the bounds of pre-described norms. This work demonstrates that a synergy approach …

Deliberation Versus Dispute: The Impact Of Argumentative Discourse Goals On Learning And Reasoning In The Science Classroom, Mark Felton, Merce Garcia-Mila, Sandra Gilabert Dec 2009

Deliberation Versus Dispute: The Impact Of Argumentative Discourse Goals On Learning And Reasoning In The Science Classroom, Mark Felton, Merce Garcia-Mila, Sandra Gilabert

Faculty Publications

Researchers in science education have converged on the view that argumentation can be an effective intervention for promoting knowledge construction in science classrooms.However, the impact of such interventions may be mediated by individuals’ task goals while arguing. In argumentative discourse, one can distinguish two overlapping but distinct kinds of activity: dispute and deliberation. In dispute the goal is to defend a conclusion by undermining alternatives, whereas in deliberation the goal is to arrive at a conclusion by contrasting alternatives. In this study, we examine the impact of these discourse goals on both content learning and argument quality in science.

Theoretical And Experimental Investigations Of Resonance Fluorescence Lidar For Measurements Of N₂ In The Auroral Atmosphere, Agatha S. Light Dec 2009

Theoretical And Experimental Investigations Of Resonance Fluorescence Lidar For Measurements Of N₂ In The Auroral Atmosphere, Agatha S. Light

Atmospheric Sciences

"In this thesis, a series of experimental and theoretical studies of the resonance fluorescence lidar system at Poker Flat Research Range (located in Chatanika, Alaska) for use in obtaining measurements of aurorally produced molecular nitrogen ions (N₂) are presented. Obtaining measurements of N₂ is made challenging by both the operational performance of the resonance lidar system and the high degree of geophysical variability inherent in the aurora. Analyses are conducted of measurements obtained by the operational sodium and iron resonance lidar systems to verify the lidar system performance. To increase the strength and quality of the lidar measurements, the telescope …

The Paradigm Recursion: Is It More Accessible When Introduced In Middle School?, Katherine Gunion, Todd Milford, Ulrike Stege

The Journal of Problem Solving

Recursion is a programming paradigm as well as a problem solving strategy thought to be very challenging to grasp for university students. This article outlines a pilot study, which expands the age range of students exposed to the concept of recursion in computer science through instruction in a series of interesting and engaging activities. In this study, a small number of students (n = 9) aged 11 to 13 years, were presented with a new and unique recursion curriculum involving hands-on experiences over a seven-week period at the University of Victoria, Canada. The curriculum was comprised of a series of …

Examining The Role Of Manipulatives And Metacognition On Engagement, Learning, And Transfer, Daniel M. Belenky, Timothy J. Nokes Dec 2009

Examining The Role Of Manipulatives And Metacognition On Engagement, Learning, And Transfer, Daniel M. Belenky, Timothy J. Nokes

The Journal of Problem Solving

How does the type of learning material impact what is learned? The current research investigates the nature of students’ learning of math concepts when using manipulatives (Uttal, Scudder, & DeLoache, 1997). We examined how the type of manipulative (concrete, abstract, none) and problem-solving prompt (metacognitive or problem-focused) affect student learning, engagement, and knowledge transfer. Students who were given concrete manipulatives with metacognitive prompts showed better transfer of a procedural skill than students given abstract manipulatives or those given concrete manipulatives with problem-focused prompts. Overall, students who reported low levels of engagement showed better learning and transfer when getting metacognitive prompts, …

Modeling Human Performance In Restless Bandits With Particle Filters, Michael S.K. Yi, Mark Steyvers, Michael Lee Dec 2009

Modeling Human Performance In Restless Bandits With Particle Filters, Michael S.K. Yi, Mark Steyvers, Michael Lee

The Journal of Problem Solving

Bandit problems provide an interesting and widely-used setting for the study of sequential decision-making. In their most basic form, bandit problems require people to choose repeatedly between a small number of alternatives, each of which has an unknown rate of providing reward. We investigate restless bandit problems, where the distributions of reward rates for the alternatives change over time. This dynamic environment encourages the decision-maker to cycle between states of exploration and exploitation. In one environment we consider, the changes occur at discrete, but hidden, time points. In a second environment, changes occur gradually across time. Decision data were collected …

Obstacles In Investigating The Role Of Restructuring In Insightful Problem Solving, Ivan K. Ash, Patrick J. Cushen, Jennifer Wiley Dec 2009

Obstacles In Investigating The Role Of Restructuring In Insightful Problem Solving, Ivan K. Ash, Patrick J. Cushen, Jennifer Wiley

The Journal of Problem Solving

In the present article, we articulate three assumptions underlying theories proposing that restructuring processes play a key role in insightful problem solving: representational difficulty, representational change, and discontinuity in solution processes. We argue that these assumptions need empirical validation to justify the proposition of restructuring mechanisms that are unique from those involved in classic information-processing theories of problem solving. To this end, we review some theoretical and methodological obstacles that are inherent in the investigation of the existence and nature of restructuring processes. We then offer some recommendations on how to overcome or avoid these obstacles in future studies. Finally, …

Multiwavelength Studies Of Lsi+61°303, Michael E. Fahrenwald Dec 2009

Multiwavelength Studies Of Lsi+61°303, Michael E. Fahrenwald

Theses and Dissertations

LSI+61°303 is a member of a small class of X-ray binary stars that are also sources of strong radio emission. It has been detected as a periodic radio source with the NRAO Very Large Array, a magnitude 10.7 B0 star, a 0.5-5 keV X-ray source by the Einstein X-ray satellite and may be associated with an unidentified 100 MeV γ-ray source discovered by the Compton Gamma Ray Observatory satellite. Theories exist which suggest that binary systems are capable of emitting γ-rays at energies > 100 GeV. A similar system, PSR B1259-63, has been found to emit γ-rays at TeV energies. In …

Carbon Coated Tellurium For Optical Data Storage, Jonathan D. Abbott Dec 2009

Carbon Coated Tellurium For Optical Data Storage, Jonathan D. Abbott

Theses and Dissertations

A highly durable optical disk has been developed for data archiving. This optical disk uses tellurium as the write layer and carbon as a dielectric and oxidation prevention layer. The sandwich style CTeC film was deposited on polycarbonate and silicon substrates by plasma sputtering. These films were then characterized with SEM, TEM, EELS, ellipsometry, ToF-SIMS, etc, and were tested for writability and longevity. Results show the films were uniform in physical structure, are stable, and able to form permanent pits. Data was written to a disk and successfully read back in a commercial DVD drive.

Simultaneous Analysis Of All Single-Nucleotide Polymorphisms In Genome-Wide Association Study Of Rheumatoid Arthritis, George Mathew, Hongyan Xu, Varghese George Dec 2009

Simultaneous Analysis Of All Single-Nucleotide Polymorphisms In Genome-Wide Association Study Of Rheumatoid Arthritis, George Mathew, Hongyan Xu, Varghese George

College of Natural and Applied Sciences

The availability of very large number of markers by modern technology makes genome-wide association studies very popular. The usual approach is to test single-nucleotide polymorphisms (SNPs) one at a time for association with disease status. However, it may not be possible to detect marginally significant effects by single-SNP analysis. Simultaneous analysis of SNPs enables detection of even those SNPs with small effect by evaluating the collective impact of several neighboring SNPs. Also, false-positive signals may be weakened by the presence of other neighboring SNPs included in the analysis. We analyzed the North American Rheumatoid Arthritis Consortium data of Genetic Analysis …
