Broadening Our Lenses Of Perception To Advance Learning: An Introduction To Multilectics, Gene Fellner
Broadening Our Lenses Of Perception To Advance Learning: An Introduction To Multilectics, Gene Fellner
Publications and Research
In Broadening our lenses of perception, I address the need to assess students through multiple lenses rather than through the dominant lens of standardized tests. I propose what I call multilectical lenses to provide multidimensional pictures of poor students of color; these highlight student skills and knowledge that tests disregard. Multilectics employs multi level analysis, sound and images to analyze the gestures and voices of students during classroom activities. In combination with student writing, the data produced by multilectical practice provide a rich foundation for advancing the academic achievement of our most underserved students.

Neuroevolution And An Application Of An Agent Based Model For Financial Market, Anil Yaman
Neuroevolution And An Application Of An Agent Based Model For Financial Market, Anil Yaman
Dissertations and Theses
Market prediction is one of the most difficult problems for the machine learning community. Even though, successful trading strategies can be found for the training data using various optimization methods, these strategies usually do not perform well on the test data as expected. Therefore, selection of the correct strategy becomes problematic. In this study, we propose an evolutionary algorithm that produces a variation of trader agents ensuring that the trading strategies they use are different. We discuss that because the selection of the correct strategy is difficult, a variety of agents can be used simultaneously in order to reduce risk. …

Simultaneous Adsorption Of 11 Volatile Organic Compounds By An Activated Carbon Made From Polystyrene Sulfonic Acid-Based Organic Salt, Alejandro Smith
Simultaneous Adsorption Of 11 Volatile Organic Compounds By An Activated Carbon Made From Polystyrene Sulfonic Acid-Based Organic Salt, Alejandro Smith
Dissertations and Theses
Activated carbon is used in water treatment worldwide due to its ability to adsorb many different contaminants from water. The high adsorption capacity of activated carbon is linked to its high internal surface area and micro/meso- porosity. In this work an activated carbon obtained from polystyrene sulfonic acid-based organic salt was examined to simultaneously adsorb eleven volatile organic compounds from aqueous solution. Adsorption data were modeled with different isotherms to determine the equilibrium adsorptive capacities for these compounds. The performance of the polymer-based activated carbon was then compared with that of a commercial wood-based activated carbon. The results indicate that …
Comparative Phylogeography Of Glassfrogs (Vitreorama) Endemic To The Brazilian Altantic Rainforest, Zoe Spanos
Comparative Phylogeography Of Glassfrogs (Vitreorama) Endemic To The Brazilian Altantic Rainforest, Zoe Spanos
Dissertations and Theses
The Brazilian Atlantic Forest harbors one of the most diverse faunas of the world, including 2-3% of all known vertebrate species. Understanding the role of both climate and landscape in shaping current biodiversity patterns has been the focus of many recent phylogeographic studies. Here I explore multiple factors thought to have impacted the generation of local diversity in the Brazilian Atlantic Forest (AF) using two montane, stream-associated species of glassfrogs – V. eurygnatha and V. uranoscopa. I integrate species distribution modeling, path analysis, and molecular data to test the role of climatic stability, rivers, mountain chains, and geographic distance in …
A Briny Crossroads Salt, Slavery, And Sectionalism In The Kanawha Salines, Cyrus Forman
A Briny Crossroads Salt, Slavery, And Sectionalism In The Kanawha Salines, Cyrus Forman
Dissertations and Theses
The Kanawha Salines are a place whose history challenges conventional narratives and popular assumptions about slavery and freedom in the antebellum South. The paradoxical nature of slavery in this locale can be seen in the identity of the first documented people forced to labor in the salt works. A half century before enslaved Africans were imported to this region, European women and their families were kidnapped, enslaved, and marched to the salt mines by Native Americans: “In 1755, the Indians had carried Mary Ingles, her newborn baby, and others as captives....to this spot on the Kanawha to attain a salt …
Methodological Advancements For Improving Performance And Generating Ensemble Ecological Niche Models, Robert Boria
Methodological Advancements For Improving Performance And Generating Ensemble Ecological Niche Models, Robert Boria
Dissertations and Theses
This study employs spatial filtering of occurrence data with the aim of reducing overfitting to sampling bias in ecological niche models (ENMs). Sampling bias in geographic space leads to localities that may also be biased in environmental space. If so, the model can overfit to those biases. As a preliminary test addressing this issue, we used Maxent, bioclimatic variables, and occurrence localities of a broadly distributed Malagasy tenrec, Microgale cowani (Family Tenrecidae: Subfamily Oryzorictinae). We modeled the abiotically suitable area of this species using three distinct datasets: unfiltered, spatially filtered, and rarefied unfiltered localities. To quantify overfitting and model performance, …

Assessing Satellite Image Data Fusion With Information Theory Metrics, James Cross
Dissertations and Theses
A common problem in remote sensing is estimating an image with high spatial and high spectral resolution given separate sources of measurements from satellite instruments, one having each of these desirable properties. This thesis presents a survey of seven families of algorithms which have been developed to provide this common pattern of satellite image data fusion. They are all tested on artificially degraded sets of satellite data from the Moderate Resolution Imaging Spectroradiometer (“MODIS”) with known ideal results, and evaluated using the commonly accepted data fusion assessment metrics spectral angle mapper (“SAM”) and Erreur Relative Globale Adimensionelle de Synth`ese (“ERGAS”). …

Finite Element Spectral Approximation With Numerical Integration For The Biharmonic Eigenvalue Problem, Max Tran
Publications and Research
We investigate the convergence properties of a mixed finite element method approximation to the Biharmonic eigenvalue problem under the presence of numerical integration. We give a brief overview of the results obtained when exact integration is used in a finite element method, then develop related theories and obtained the convergence rates when numerical quadrature is taken into account. The standard approach to obtaining error estimate of variational eigenvalue problems is based on the error estimate of the solution operators of the source problems. The important issues are the rate of convergence of the solution operators and the conditions required for …
Chemistry Students’ Attitudes About Peer-Led Team Learning Workshops: Comparison To The Six Critical Components, A.E. Dreyfuss, Janet Liou-Mark, Leo Gafney
Chemistry Students’ Attitudes About Peer-Led Team Learning Workshops: Comparison To The Six Critical Components, A.E. Dreyfuss, Janet Liou-Mark, Leo Gafney
Publications and Research
While tracking students’ performance and perseverance is important to determine the effect of the incorporation of workshops in courses, little has been published on students’ attitudes toward workshops: How do students feel about PLTL workshops? One method of examining this question is through a questionnaire developed by Gafney. This paper will present the results of a three-semester study using this questionnaire on how students view workshop in their introductory chemistry courses.

To improve any PLTL program, feedback from Peer Leaders is necessary and beneficial. Their experiences, ideas, and honest critiques will assist in shaping the program to meet its ultimate goal: To ensure all students are engaged in their learning process through an active community setting.
Technology And Wonder In Thirteenth-Century Iberia And Beyond, Christopher B. Swift
Technology And Wonder In Thirteenth-Century Iberia And Beyond, Christopher B. Swift
Publications and Research
As the desire for affective experiences of the sacred increased in communities across Europe in the late Middle Ages, the Christian faithful crafted lifelike, mechanized figures of Christ, the Virgin Mary, and saints for use in religious festivals. Although each devotional culture evidences unique body/object relationships and meanings, in general animated ritual objects encouraged lay participation in the celebration of saints and the Passion by engaging the senses, and, consequently, an emotional sense of God. In this essay I investigate the ritual alliances between moveable, prop-like saints and their Iberian devotees, in particular the performative meanings that arose from encounters …

Publications and Research
How would students respond to open-ended questions regarding their experiences with PLTL workshops? This paper will present the results of a two-semester qualitative study on how students view workshop in their introductory chemistry courses, using Brookfield’s (1995) Critical Incident Questionnaire (CIQ). The five questions probe what stands out in the affirmative and negative, using key words: engaged, distanced, affirmed, puzzled or confused, and surprising. Collecting key moments from students in workshop, after several weeks of meeting, allow a grounded sense of how students view the workshop experience.

Background: For patients with deep brain stimulators (DBS), local absorbed radiofrequency (RF) power is unknown and is much higher than what the system estimates. We developed a comprehensive, highquality brain magnetic resonance imaging (MRI) protocol for DBS patients utilizing three-dimensional (3D) magnetic resonance sequences at very low RF power. Methods: Six patients with DBS were imaged (10 sessions) using a transmit/receive head coil at 1.5 Tesla with modified 3D sequences within ultra-low specific absorption rate (SAR) limits (0.1 W/kg) using T2, fast fluid-attenuated inversion recovery (FLAIR) and T1- weighted image contrast. Tissue signal and tissue contrast from the low-SAR images …

A growing number of studies are evaluating retinal progenitor cell (RPC) transplantation as an approach to repair retinal degeneration and restore visual function. To advance cell-replacement strategies for a practical retinal therapy, it is important to define the molecular and biochemical mechanisms guiding RPC motility. We have analyzed RPC expression of the epidermal growth factor receptor (EGFR) and evaluated whether exposure to epidermal growth factor (EGF) can coordinate motogenic activity in vitro. Using Boyden chamber analysis as an initial high-throughput screen, we determined that RPC motility was optimally stimulated by EGF concentrations in the range of 20-400 ng/ml, with decreased …
