Creative Movement And Dance Integration: Their Connection To Learning Third Grade Math Concepts, Lashandria L. Redman

Master's Theses

In education, there are various methods of instruction used to engage students and strengthen learning of academic concepts. One method that can be used is arts integration. Arts integration is a pathway to learning that integrates an art form with another subject. Using movement and dance to help teach concepts that are part of an academic discipline is dance integration. This thesis involves dance integration and examines creating and presenting a movement and dance-integrated curriculum that teaches concepts that are part of the math discipline. The study explores how the movement and a dance-integrated curriculum affects student behavior and learning, …

Willingness To Pay For Irrigation Water Under Scarcity Conditions, Tyler Robert Knapp

Graduate Theses and Dissertations

Reliance of Arkansas agricultural producers on groundwater for irrigation has led to depletion of the Mississippi River Valley alluvial aquifer. Without intervention, consequences include insufficient groundwater to meet irrigation demand as well as drawdown of the deeper Sparta Aquifer, upon which communities in eastern Arkansas rely for non-agricultural use. Among proposed solutions to combat groundwater decline is the construction of off-farm surface water infrastructure to meet the irrigation needs of producers. Despite the importance of irrigated agriculture to Arkansas, there is little know about the economic value of irrigation water to producers. Thus, we implement a double-bounded dichotomous choice contingent …

Improved Methodology For Developing Non-Motorized Safety Perfomance Functions, Keneth Morgan Kwayu

Masters Theses

This study aimed at improving the methodology for developing statewide non-motorized safety performance functions (SPFs). Due to lack of pedestrian and bicyclist counts, the methodology proposed a procedure for developing statewide surrogate non-motorized exposure measures using data that are available at statewide level. Eleven years non-motorized crashes at signalized urban intersections joining Arterial and Collector roads in Michigan were used to test the procedure.

The study also explored the use of Bayesian approach for modeling non-motorized crashes as an alternative to traditional classical count data models. Classical count data models that were considered as potential fit to the data include; …

Kin Selection And Its Discontents, David C. Queller

Biology Faculty Research

Kin selection is a core aspect of social evolution theory, but a small number of critics have recently challenged it. Here I address these criticisms and show that kin selection remains an important explanation for much (though not all) social evolution. I show how many of the criticisms rest on historical idiosyncrasies of the way the field happened to develop, rather than on the real logic and evidence.

Grouping Techniques To Manage Large-Scale Multi-Item Multi-Echelon Inventory Systems, Anvar Abaydulla

Graduate Theses and Dissertations

Large retail companies operate large-scale systems which may consist of thousands of stores. These retail stores and their suppliers, such as warehouses and manufacturers, form a large-scale multi-item multi-echelon inventory supply network. Operations of this kind of inventory system require a large number of human resources, computing capacity, etc.

In this research, three kinds of grouping techniques are investigated to make the large-scale inventory system “easier” to manage. The first grouping technique is a network based ABC classification method. A new classification criterion is developed so that the inventory network characteristics are included in the classification process, and this criterion …

Exploiting The Principal Parametric Resonance Of An Rlc" Circuit For Vibratory Energy Harvesting", Nicholas B. Caldwell

All Theses

The use of ambient energy sources to independently power small electronic devices, a process commonly known as energy harvesting, has recently become a focus of research due to advances in low-power electronic applications. A particular class of energy harvesting devices, known as vibratory energy harvesters (VEHs), utilizes low-level vibrations present in numerous natural and man-made environments to generate electrical energy for electronic devices.

This work investigates the use of a new technique to harvest energy from ambient vibrations by parametrically exciting a resonance condition of the electric current in a nonlinear oscillating circuit. To accomplish this parametric resonance phenomenon, we …

The Decay Of Disease Association With Declining Linkage Disequilibrium: A Fine Mapping Theorem, Mehdi Maadooliat, Naveen K. Bansal, Jibal Upadhya, Manzur R. Farazi, Xiang Li, Max M. He, Scott J. Hebbring, Zhan Ye, Steven J. Schrodi

Mathematics, Statistics and Computer Science Faculty Research and Publications

Several important and fundamental aspects of disease genetics models have yet to be described. One such property is the relationship of disease association statistics at a marker site closely linked to a disease causing site. A complete description of this two-locus system is of particular importance to experimental efforts to fine map association signals for complex diseases. Here, we present a simple relationship between disease association statistics and the decline of linkage disequilibrium from a causal site. Specifically, the ratio of Chi-square disease association statistics at a marker site and causal site is equivalent to the standard measure of pairwise …

Impact Of Myh6 Variants In Hypoplastic Left Heart Syndrome, Aoy Tomita-Mitchell, Karl D. Stamm, Donna K. Mahnke, Min-Su Kim, Pip M. Hidestrand, Huan-Ling Liang, Mary Goetsch, Pippa Simpson, Andrew N. Pelech, James S. Tweddell, D. Woodrow Benson, John Lough, Michael E. Mitchell

Mathematics, Statistics and Computer Science Faculty Research and Publications

Hypoplastic left heart syndrome (HLHS) is a clinically and anatomically severe form of congenital heart disease (CHD). Although prior studies suggest that HLHS has a complex genetic inheritance, its etiology remains largely unknown. The goal of this study was to characterize a risk gene in HLHS and its effect on HLHS etiology and outcome. We performed next-generation sequencing on a multigenerational family with a high prevalence of CHD/HLHS, identifying a rare variant in the α-myosin heavy chain (MYH6) gene. A case-control study of 190 unrelated HLHS subjects was then performed and compared with the 1000 Genomes Project. Damaging …

A Note On The Howson Property In Inverse Semigroups, Peter R. Jones

Mathematics, Statistics and Computer Science Faculty Research and Publications

An algebra has the Howson property if the intersection of any two finitely generated subalgebras is again finitely generated. A simple necessary and sufficient condition is given for the Howson property to hold on an inverse semigroup with finitely many idempotents. In addition, it is shown that any monogenic inverse semigroup has the Howson property.

The Coronary Circulation In An In Vitro Multi-Scale Model Of The Stage 1 Norwood Procedure, Lauren Elizabeth Carter

All Theses

Hypoplastic Left Heart Syndrome (HLHS) is a congenital heart disease where the left ventricle and ascending aorta are underdeveloped. The first of three palliative surgeries for this malformation is the Norwood procedure. In this surgery, an opening is made between the left and right atrium so that all blood can flow into the right ventricle (RV). A reconstructed aorta is anastomosed (connected) to the RV so that the RV can pump oxygenated blood to the body (the systemic circulation). To divert part of the systemic blood flow to the pulmonary circulation, the modified Blalock-Taussig Shunt (mBTS) is connected from the …

Investigating Employee Engagement Through A Self-Determination Theory Framework, Crystal S. Wiedemann

All Theses

Over the last decade, the concept of employee engagement has attractedsubstantial attention in both research settings and organizational applications (Christian,Garza, & Slaughter, 2011). Research has shown employee engagement to be related toseveral positive organizational outcomes, including employee production, employeeretention, customer satisfaction and company profit (Harter, Schmidt, & Hayes, 2002;Hewitt Associates LLC, 2005). While there has been a recent surge of academic interestin employee engagement, there remains much to be learned about its antecedents. Thisstudy investigates employee engagement within the more established motivationalframework of Self-Determination Theory (Deci & Ryan, 1985; Ryan & Deci, 2000) asproposed by Meyer and Gagne (2008) to …

These models provide a thorough physical display in 3D with detailed information related to the morphology of internal structures and their spatial location with surrounding structures. The aim of this study was to develop a brain substitute material based on gelatin that simulates the mechanical properties of brain tissue. Tissue mimicking materials were developed by matching the mechanical properties of porcine brain tissue under compressive loading at strain rates typical of surgical …

Estimation Of Annual Average Daily Traffic (Aadt) And Missing Hourly Volume Using Artificial Intelligence, Sababa Islam

All Theses

Annual Average Daily Traffic (AADT) is one of the most important traffic parameters used in transportation engineering analysis. Moreover, each state Department of Transportation (DOT) must report the AADT data to Federal Highway Administration (FHWA) annually as part of the Highway Performance Monitoring System (HPMS) requirements. For this reason, state DOTs continually collect AADT data via permanent count stations and short-term counts. In South Carolina, only interstates and primary routes are equipped with permanent count stations. For the majority of the secondary routes, AADT data are estimated based on short-term counts or are simply guesstimated based on their functional classifications. …

The Corona Problem For Kernel Multiplier Algebras, Eric T. Sawyer, Brett D. Wick

Mathematics Faculty Research

We prove an alternate Toeplitz corona theorem for the algebras of pointwise kernel multipliers of Besov-Sobolev spaces on the unit ball in C, and for the algebra of bounded analytic functions on certain strictly pseudoconvex domains and polydiscs in higher dimensions as well. This alternate Toeplitz corona theorem extends to more general Hilbert function spaces where it does not require the complete Pick property. Instead, the kernel functions kx (y) of certain Hilbert function spaces H are assumed to be invertible multipliers on H and then we continue a research thread begun by Agler and McCarthy in 1999, and continued …

Kinematics Card Sort Activity: Insight Into Students’ Thinking, Erin Berryhill, Deborah Herrington, Keith Oliver

Peer Reviewed Articles

Kinematics is a topic students are unknowingly aware of well before entering the physics classroom. Students observe motion on a daily basis. They are constantly interpreting and making sense of their observations, unintentionally building their own understanding of kinematics before receiving any formal instruction. Unfortunately, when students take their prior conceptions to understand a new situation, they often do so in a way that inaccurately connects their learning. We were motivated to identify strategies to help our students make accurate connections to their prior knowledge and understand kinematics at a deeper level. To do this, we integrated a formative assessment …

Food And Energy For All, Bradley Stevens, Stephen Rybczynski, Deborah Herrington

Peer Reviewed Articles

When asked what plants need for photosynthesis, many students can correctly recall the reaction equation and state that plants require CO2, H2O, and light. Many students, however, do not understand that these reactants are the raw materials plants use to make sugars and instead believe that they are food for plants. Moreover, when questioned further, students often voice the idea that plants get their food from the soil (Kestler 2014). This is consistent with findings that fewer than half of current middle and high school students have a correct understanding of the process of photosynthesis (AAAS 2015). We developed this …

Kno.e.sis Publications

We present the results of analyzing gait motion in first-person video taken from a commercially available wearable camera embedded in a pair of glasses. The video is analyzed with three different computer vision methods to extract motion vectors from different gait sequences from four individuals for comparison against a manually annotated ground truth dataset. Using a combination of signal processing and computer vision techniques, gait features are extracted to identify the walking pace of the individual wearing the camera as well as validated using the ground truth dataset. Our preliminary results indicate that the extraction of activity from the video …

Quiescent‐Explosive Transitions During Dome‐Forming Volcanic Eruptions: Using Seismicity To Probe The Volcanic Processes Leading To The 29 July 2008 Vulcanian Explosion Of Soufrière Hills Volcano, Montserrat, Mel Rodgers, Patrick J. Smith, Tamsin A. Mather, David M. Pyle

School of Geosciences Faculty and Staff Publications

The July 2008 vulcanian explosion at Soufrière Hills Volcano (SHV), Montserrat, was preceded by one of the largest seismic swarms observed since the start of the eruption. We analyze the spectral and waveform properties of the earthquakes in this swarm and compare these observations to models of subsurface volcanic processes. We observe an initial volcano‐tectonic (VT) swarm, followed by a large low‐frequency (LF) swarm. We observe that the spectral content of LF events changes over time to carry more energy at lower frequencies. This shift to a lower frequency spectral content is concurrent with an increase in LF event rates. …

What’S Scale Got To Do With It? Models For Urban Tree Canopy, Dexter H. Locke, Shawn M. Landry, J. M. Grove, Rinku R. Chowdhury

School of Geosciences Faculty and Staff Publications

The uneven provisioning of ecosystem services has important policy implications; yet the spatial heterogeneity of tree canopy remains understudied. Private residential lands are important to the future of Philadelphia’s urban forest because a majority of the existing and possible tree canopy is located on residential land uses. This article examines the spatial distribution of tree canopy in Philadelphia, PA and its social correlates. How are existing tree canopy and opportunities for additional tree canopy distributed across the city of Philadelphia and with respect to three explanations: (i) population density, (ii) the social stratification luxury effect, and 3) lifestyle characteristics of …
