Effect Of Small Class Setting On The Algebra I Achievement Of Ninth-Grade Students, Lisa Kissire

College of Education Dissertations

The effects of class size on student outcomes has been widely studied at the elementary level. Many such studies have found important relationships between class size and outcome in the areas of academic achievement, student discipline, and teacher retention. However, little attention has been given to the examination of how class size may affect student outcomes in the middle school and high school levels. The purpose of this nonexperimental study was to examine the effects of class size setting, gender, socioeconomic status, and school configuration on the Algebra I achievement of ninthgrade students. Participants were drawn from four rural schools …

Inter-Relationships Linking Probability Of Becoming A Case Of Nicotine Dependence With Frequency Of Tobacco Cigarette Smoking, Olga A. Vsevolozhskaya, James C. Anthony

Biostatistics Faculty Publications

INTRODUCTION: Once smoking starts, some tobacco cigarette smokers (TCS) can make very rapid transitions into tobacco dependence syndromes (TCD). With adjustment for smoking frequency, we posit female excess risk for this rapid-onset TCD. In a novel application of functional analysis for tobacco research, we estimate four Hill function parameters and plot TCD risk against a gradient of smoking frequency, as observed quite soon after smoking onset.

METHODS: In aggregate, the National Surveys of Drug Use and Health, 2004-2013, identified 1546 newly incident TCS in cross-sectional research, each with standardized TCD assessment.

RESULTS: Hill function estimates contradict our apparently over-simplistic hypothesis. …

Pushback: Critical Data Designers And Pollution Politics, Kim Fortun, Lindsay Poirier, Alli Morgan, Brandon Costelloe-Kuehn, Mike Fortun

Statistical and Data Sciences: Faculty Publications

In this paper, we describe how critical data designers have created projects that ‘push back’ against the eclipse of environmental problems by dominant orders: the pioneering pollution database Scorecard, released by the US NGO Environmental Defense Fund in 1997; the US Environmental Protection Agency’s EnviroAtlas that brings together numerous data sets and provides tools for valuing ecosystem services; and the Houston Clean Air Network’s maps of real-time ozone levels in Houston. Drawing on ethnographic observations and interviews, we analyse how critical data designers turn scientific data and findings into claims and visualisations that are meaningful in contemporary political terms.

The Influence Of Student, Neighborhood, And School Factors On College Readiness : An Examination Of Factors Combined As A Result Of Implementing A Race- And Socioeconomically-Based Student Assignment Plan., Gregory Paul Herberger

Electronic Theses and Dissertations

In 2006, Meredith v. Jefferson County Board of Education determined race-based student assignment plans violated the 14th Amendment. Through the assistance of Orfield and Frankenberg (2011), Jefferson County Public Schools (JCPS) reconfigured the district’s race-based student assignment and implemented a race- and socioeconomic-based student assignment plan. The purpose of this study was to examine students’ backgrounds and school composition factors within a race- and socioeconomic-based assignment plan to determine the extent the factors are related to college readiness. Based on data obtained from 3,018 Grade 11 students, hierarchical linear multiple regression was used to examine the utility of student background, …

Comparison Of Two Methods For Developing Aggregate Population-Based Models, Oyebola E. Oyero

Electronic Theses and Dissertations

Aggregate models incorporate the variation between individual parameters of individualbased models to construct a population-based model. This thesis focuses on the comparison of two different methods for creating these population-based models. The first method, the individual parameter distribution technique (IPD) focuses on the similarities and variation of parameters in an individual-based model as calculated using individual data sets [4]. The second method we consider is the nonlinear mixed effect method (NLME), which is primarily used in modeling repeated measurement data. In the NLME approach, both the fixed effects and random effects of the parameter values are estimated in the model …

Complex Vegetation Dynamics At The Fire–Grazing–Drought Nexus, Christine H. Bielski

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The discipline of ecology long ago moved away from viewing systems as static entities where disturbance processes, environmental stochasticity, and spatiotemporal variability play minor roles in determining ecosystem structure and function. Ecological theory continue to develop frameworks and statistical techniques capable of describing the inherent complexity in natural systems. However, in dealing with the complexity in nature, many applied disciplines have yet to adopt such frameworks or statistical techniques. The objective of this study was bridge the gap between ecological theory and application by using complex systems theory to describe grassland vegetation dynamics at the fire-grazing-drought nexus. Chapters 2 and …

The Effects Of Active Learning Technology On Instructors’ Practices And Students’ Engagement And Grades: A Mixed Methods Study, Jeremy C. Van Hof

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Partly in response to university teachers’ changing pedagogies marked by flipping instruction, lecture capture technologies are evolving into active learning systems. Little published research exists on the effects of active learning technology on either teachers or students. This two-phase sequential explanatory mixed methods study details the effects that active learning systems have on instructor practices and on student grades and engagement. Phase one combined quantitative data collection with instructor interviews. Phase one findings show higher student engagement levels correlate with the use of the active learning system only in the presence of very specific, flipped classroom practices. Phase two, a …

Design And Synthesis Of Novel Octacarboxy Porphyrinic Metal–Organic Frameworks, Jacob A. Johnson

Department of Chemistry: Dissertations, Theses, and Student Research

Metal-Organic Frameworks (MOFs) are a class of nanoporous crystalline materials constructed via the interconnection between metal-ions/inorganic clusters and organic ligands. Since the surface area, pore size and distribution, and chemical functionalities of MOFs are highly tunable via the judicious combinations of inorganic clusters and organic ligands, MOFs have attracted intensive interests for a variety of applications including gas adsorption and separation, catalysis, chemical sensing, and drug delivery among others. Porphyrin based ligands are of particular interest for building functional MOFs due to their unique photo-, electro-, and catalytic properties. In addition, the four-fold symmetry of porphyrin ligands offers an effective …

A Robotic Device To Assist With In-Vivo Measurement Of Human Pelvic Organ Tissue Properties, Shashank S. Kumat

Mechanical and Aerospace Engineering Theses - Archive

Measurement of the biomechanical properties of human pelvic organ tissue without undergoing minimally invasive surgery is desired for diagnostics purposes and take precautionary actions if needed. The biomechanical properties of the bladder change with age and due to diseases. Thus, identification of the viscoelastic properties of the tissue could help in detecting early stages of the disease in the bladder. A literature survey revealed that no device exists that could be used to characterize the biomechanical properties of the human bladder in-vivo. This research contributes towards the development of a diagnostic system that could be used in a medical setting …

The Influence Of Functional Weights On The Performance Of Least Squares Finite Element Formulation On Hybrid Meshes, Anirudh Rajagopal

Mechanical and Aerospace Engineering Theses - Archive

The Least-Squares Finite Element Method (LSFEM) is a numerical method for solving partial differential equations (PDE) approximately by minimizing the L-2 norm of the PDE residuals. Unlike the more common Galerkin approach, this method does not employ integration by parts to reduce the continuity requirements of the basis functions. Instead, the PDE is cast as a first-order system of differential equations, which allows for the solution of primary and secondary variables with the same order of accuracy. In addition, this approach always leads to a direct minimization problem and therefore not subject to the restrictive inf-sup condition and does not …

Shape Optimization Of Helical Coil Tube For Maximizing Heat Transfer, Venkat Manoj Kandukuri

Mechanical and Aerospace Engineering Theses - Archive

Many researchers have observed the enhancement of heat transfer in coiled tubes compared to straight tubes with the same diameter and length. It is known fact, that in a helical coil tube the maximum axial velocity shifted towards the outer wall of the pipe and imbalance between centrifugal forces and inertial loads to a secondary motion of the fluid in the cross-section of the tube. This secondary motion is responsible for improved transport of heat energy to/from the tube walls. Previous conducted Experimental and computational parametric studies show the relationship between the increased heat transfer and parameters such as pitch, …

Subtractive Methods To Form Pyrite And Sulfide Nanostructures Of Fe, Co, Ni, Cu And Zn, Kurt W. Kolasinski

Chemistry Faculty Publications

The low Z metals Fe, Co, Ni, Cu and Zn are Earth abundant, i.e. inexpensive, and their sulfides are of low toxicity. This makes them appealing candidates for materials applications requiring semiconductors or, in the case of CoS₂, a metal since they can potentially be produced in large quantities and low cost. Though of great potential little work has explored how subtractive methods can be used to form nanostructured and/or porous structures in, e.g. FeS₂, CoS₂, NiS, Cu₂S and ZnS.

Sensor Management For Localization And Tracking In Wireless Sensor Networks, Nianxia Cao

Dissertations - ALL

Wireless sensor networks (WSNs) are very useful in many application areas including battlefield surveillance, environment monitoring and target tracking, industrial processes and health monitoring and control. The classical WSNs are composed of large number of densely deployed sensors, where sensors are battery-powered devices with limited signal processing capabilities. In the crowdsourcing based WSNs, users who carry devices with built-in sensors are recruited as sensors. In both WSNs, the sensors send their observations regarding the target to a central node called the fusion center for final inference. With limited resources, such as limited communication bandwidth among the WSNs and limited sensor …

The Pace And Timing Of Changing Landscapes As Viewed Through Cosmogenic Radionuclides: Synthetic And Real Examples From The Central Andes And Amazonia, Pedro Val

Dissertations - ALL

In the past three decades, the use of cosmogenic radionuclides revolutionized research in geomorphology. Cosmogenic radionuclides, such as 10Be and 26Al, accumulate within quartz crystals at a relatively well-constrained rate due to the bombardment of the Earth’s atmosphere by cosmic rays. Since the early 90’s, many studies utilized 10Be and 26Al to determine the pace and timing of vertical changes, or absence thereof, to the uppermost meters of the Earth’s surface. In particular, the ability to simply collect a bag of sand from the bottom of a stream and, after extracting the quartz from it, determine the average rate of …

Robust Kullback-Leibler Divergence And Its Applications In Universal Hypothesis Testing And Deviation Detection, Pengfei Yang

Dissertations - ALL

The Kullback-Leibler (KL) divergence is one of the most fundamental metrics in information theory and statistics and provides various operational interpretations in the context of mathematical communication theory and statistical hypothesis testing. The KL divergence for discrete distributions has the desired continuity property which leads to some fundamental results in universal hypothesis testing. With continuous observations, however, the KL divergence is only lower semi-continuous; difficulties arise when tackling universal hypothesis testing with continuous observations due to the lack of continuity in KL divergence.

This dissertation proposes a robust version of the KL divergence for continuous alphabets. Specifically, the KL divergence …
