The Impact Of Flipped Learning On Student Academic Performance And Perceptions, Mark J. Dusenbury, Myrna R. Olson

Teaching & Learning Faculty Publications

The purpose of this study was to explore if flipped learning has an impact on aviation students perceptions and academic performance in a human factors course. A total of 81 students from a large Midwestern university participated. The Course Evaluation Survey (CES) was used to measure student perceptions, while course exams were used to measure academic performance. To analyze the data, the researchers use paired sample t-tests, independent sample t-tests, and a MANCOVA. Findings show students in the flipped classroom did not perform better than the lecture classroom. In addition, students in the lecture group had significantly higher overall course …

Biochemical And Biophysical Studies Of Vision Loss: Cataract And Macular Degeneration, Michael C. Vega

Graduate Research Theses & Dissertations

Age-related biochemical and biophysical changes to the structural properties of ocular lens membrane proteins and retinal pigment epithelium (RPE) cells are thought to play an underlying role in the etiology and progression of age-related cataract and macular degeneration. This dissertation work studies biophysical properties of biomimetic membranes to aid in further understanding of the role of aquaporin-0 in cataract pathogenesis and the biochemical composition of age-related pigmented granules, melanolipofuscin, and their implications in macular degeneration.

Cataract is the leading cause of blindness globally and is characterized by the opacification of the ocular lens. As a key optical component of the …

Nanomaterials Of Iron Oxide, Boron, And Boron Nitride: On The Path To Magnetic Guided Bioconjugates For Medical Applications, John Ryan Wozny

Graduate Research Theses & Dissertations

The functionalization of boron-based bioconjugates has long been studied for their potential use as a drug candidate for boron neutron capture therapy (BNCT). Also, magnetic nanoparticles have received greater attention due to their interesting magnetic properties and behaviors for selectively guiding them with an external magnetic field through the blood. A combination of the two ideas gives the framework for nanotechnology that has the potential to revolutionize drug delivery systems. This thesis will focus systematically on individual elements required for the many moving pieces required for magnetic drug targeting.

The research discussed in this thesis is divided into three parts. …

Course Taking And Teacher Data-Driven Decision Making Self-Efficacy And Anxiety: A Secondary Analysis, Valerie M. Hamilton

Graduate Research Theses & Dissertations

An expanding culture of accountability in education has led to an influx in the amount and types of data teachers are expected to collect and use to increase student achievement. Research has identified data-driven decision making (DDDM) as a way for teachers to use educational data to promote more effective instruction and ultimately, to better student outcomes. Despite available data and research that supports the use of DDDM, using it to make instructional decisions is still a struggle for teachers. Therefore, this study looks at the relationship between DDDM-related coursework and teacher self-efficacy and anxiety for DDDM. In theory, DDDM-related …

Kinesiology Faculty Publications and Presentations

The Assess2Perform Bar Sensei is a device used to measure barbell velocity for velocity-based training that has not yet been validated. The purpose of this study was to determine criterion validity and reliability of the Assess2Perform Bar Sensei in barbell back squats by comparing it against the GymAware PowerTool, a previously validated instrument. Sixteen injury-free, resistance-trained subjects (eleven males and five females) were recruited. Subjects were tested for their back squat one repetition maximum (1RM). Then, on two separate days, subjects performed two sets of three repetitions at loads of 45%, 60% and 75% 1RM. The GymAware PowerTool and Bar …

Explicitly Teaching Scientific Argumentation: Using Action Research To Study High School Science Readiness And Detracking, Ami Lefevre

Dissertations

Access to advanced-level science courses can be difficult for those students who start in a tracked system. Tracking is an educational practice where students are assigned to different classes based on ability level. African American and Hispanic students are most at risk since most minority students are found in the lower level track (Burris, 2014; Mehan, 2015; Oakes, 2005). This investigation used an action research approach to determine how explicitly taught elements of scientific argumentation would impact student mastery of argument skills and influence instructional practices by a professional learning community. A mixed method study was used to collect qualitative …

Perceptions Of High School Principals Of The Role Of Multi-Tiered Systems Of Support-- Formally Rti-- In Bringing About Social Justice And Equity For Black Boys, La Wanna Marie Wells

Dissertations

Historically, Black males are disproportionately represented as the least likely to graduate at every level of education and the demographic most likely placed in Special Education courses, incarcerated, as victims of homicide and who live in poverty. The United States of America implemented a voluntary program, Multi-tiered Systems of Support for educators to "intervene" with proactive measures that target groups that systemically fail: students of color, English learners, students with disabilities and the poor. The purpose of this research is to observe the perceptions of school principals who have implemented Multi-tiered Systems of Support (MTSS) as an education program for …

Digital Transformation Through Internet Of Things Services, Tayfun Keskin, Frederick J. Riggins

Information Systems Faculty Publications

Internet of Things (IoT) have been disrupting industries through shifting novel services, and business models. Organizations should also redesign their business service models to navigate this disruption. A holistic understanding of digital transformation through IoT requires the cooperation of multiple disciplines ranging from engineering to economics. This paper utilizes a conceptual model to develop an analytical framework to investigate a number of pricing strategies enabled by different business models. Our findings demonstrate that the Internet of Things phenomenon has the potential to disrupt the way we do business by connecting markets and enabling new business models.

K -Isocoronal Tilings, Eduard C. Taganap, Ma. Louise Antonette N. De Las Peñas

Mathematics Faculty Publications

In this article, a framework is presented that allows the systematic derivation of planar edge-to-edge k-isocoronal tilings from tile-s-transitive tilings, s k. A tiling T is k-isocoronal if its vertex coronae form k orbits or k transitivity classes under the action of its symmetry group. The vertex corona of a vertex x of T is used to refer to the tiles that are incident to x. The k-isocoronal tilings include the vertex-k-transitive tilings (k-isogonal) and k-uniform tilings. In a vertex-k- transitive tiling, the vertices form k transitivity classes under its symmetry group. If this tiling consists of regular polygons then …

Remarks On Suzuki's Epimorphism Number, Patrick Shanahan

Mathematics, Statistics and Data Science Faculty Works

A partial order on prime knots can be defined by declaring ��≥��, if there exists an epimorphism from the knot group of �� onto the knot group of ��. Suppose that �� is a 2-bridge knot that is strictly greater than �� distinct, nontrivial knots. In this paper, we determine a lower bound on the crossing number of �� in terms of ��. Using this bound, we answer a question of Suzuki regarding the 2-bridge epimorphism number EK(��) which is the maximum number of nontrivial knots which are strictly smaller than some 2-bridge knot with crossing number ��. We establish …

Finite N-Quandles Of Torus And Two-Bridge Links, Alissa Crans, Blake Mellor, Patrick Shanahan

On The Structure Of Hom Quandles, Alissa Crans

Mathematics, Statistics and Data Science Faculty Works

We continue the study of the quandle of homomorphisms into a medial quandle begun in [2]. We show that it suffices to consider only medial source quandles, and therefore the structure theorem of [11] provides a characterization of the Hom quandle. In the particular case when the target is 2-reductive this characterization takes on a simple form that makes it easy to count and determine the structure of the Hom quandle

Improved Prediction Of Periodicity Using Quartet Approximation In A Lattice Model Of Intracellular Calcium Release, Robert J. Rovetti

Mathematics, Statistics and Data Science Faculty Works

This study uses a probabilistic cellular automata (PCA) to model the spatial and temporal dynamics of calcium release units (CRUs) within cardiac myocytes. The CRUs are subject to random activation, nearest-neighbor recruitment, and temporal refractoriness, and their interactions produce a physiologically-important condition called calcium alternans, a beat-to-beat oscillation in the amount of calcium released. In the PCA this manifests as a transition to period-2 behavior in the fraction of activated lattice sites. We investigate this phenomenon using PCA simulations and moment-closure approximation methods of zero order (mean-field), first order (pair), and second order (quartet). We show that only the quartet …

Construction Of A Scale Of Contemplative Practice In Higher Education: An Exploratory Study, Maryann Krikorian, R. T. Busse

School of Education Faculty Works

Some scholars have formed a more expansive view of knowledge that moves beyond the cognitive notion of intellect. For example, emotional intelligence theory posits that human intelligence encompasses both cognitive and emotional competencies, providing a framework for a relatively new concept known as contemplative practice. The purposes of this study were: (a) to develop a self-report measure, the Scale of Contemplative Practice in Higher Education (SCOPE), and (b) to explore issues of validity and reliability related to the SCOPE. An extensive review of the literature, reference to personal experiences, and consultation with an expert panel were used to generate scale …

Thermostability And Excision Activity Of Polymorphic Forms Of Hogg1, Kathryn Mouzakis

Chemistry and Biochemistry Faculty Works

Objectives: Reactive oxygen species (ROS) oxidize guanine residues in DNA to form 7,8-dihydro-oxo-2′-deoxyguanosine (8oxoG) lesions in the genome. Human 8-oxoguanine glycosylase-1 (hOGG1) recognizes and excises this highly mutagenic species when it is base-paired opposite a cytosine. We sought to characterize biochemically several hOGG1 variants that have been found in cancer tissues and cell lines, reasoning that if these variants have reduced repair capabilities, they could lead to an increased chance of mutagenesis and carcinogenesis. Results: We have over-expressed and purified the R46Q, A85S, R154H, and S232T hOGG1 variants and have investigated their repair efficiency and thermostability. The hOGG1 variants showed …

Green Chemistry In United States Science Policy, Emily Jarvis

Chemistry and Biochemistry Faculty Works

Although optimizing each of the Twelve Principles of Green Chemistry is necessary for achieving the greenest possible chemistry in the lab, there are additional creative ways to promote green chemistry not encompassed by these. Communicating to society the importance of green chemistry beyond the laboratory is essential. Of course, doing this effectively presents distinct challenges to those encountered when designing chemical syntheses. Here, I discuss several observations from my time working in federal science policy as an American Association for the Advancement of Science/American Chemical Society Congressional Science Fellow in the United States Senate. I suggest a practical science policy …

Williams Honors College, Honors Research Projects

This honors project will also serve as an engineering senior design project.

The objective is to design and build the software and electrical systems for a 60 lb weight class combat robot that will function autonomously and outperform manually driven robots during competition.

While running autonomously, the robot will use LiDAR sensors to detect and attack opponent robots. This robot will also be able to be remote controlled in manual mode. This will mitigate the risk in case the autonomy or sensors fail. LED lights on the robot will indicate whether it is in autonomous or manual mode. The system …

Visual Programming Language With Natural User Interface, Matthew Britton

Williams Honors College, Honors Research Projects

One of the fastest-growing fields of interest in computer science, fueled primarily by gaming, is the Natural User Interface (NUI). NUI encompasses technologies which would replace the typical mouse-and-keyboard approach to interaction with computer systems, with the goal of making human-computer interactions more similar to face-to-face interpersonal interactions. This is done by using technologies such as gesture recognition or speech recognition and speech synthesis, which use interpersonal skills we learn and practice on a daily basis. Visual Programming Languages (VPLs) are languages that allow the creation of a program by arranging graphical representations of program behavior, rather than textual program …

Williams Honors College, Honors Research Projects

Prematurity and low birth weight are leading causes of infant death. Throughout recent years care methods for this population have evolved from incubator care to Kangaroo Mother Care (KMC). The purpose of this systematic review was to answer the following PICO question: in the case of preterm and low birth weight (LBW) infants, how does the technique of Kangaroo Mother Care (KMC) compare to traditional incubator use, regarding long and short-term outcomes of preterm and LBW infant recovery. Methods of this study included the selection of twenty peer-reviewed articles that studied the effect of incubators and KMC on premature and …

Theoretical Study Of Fano Resonance In A Mechanical System, Alex Alberts

Williams Honors College, Honors Research Projects

Resonance conditions are a major area of study in theoretical and experimental investigation. Normally, a resonance condition is characterized by a symmetric shape on either side of the resonance. In some cases, we can observe an asymmetric resonance shape, which is called a Fano resonance. We will study the appearance of Fano resonance in a purely mechanical system. The frequency response of the primary system is approximated using the method of multiple scales focusing on the location of the resonance condition. Then, curve fitting is used to approximate the Fano parameter associated with the system, which provides a measurement of …
