Exploring The Relationship Between K-8 Prospective Teachers’ Algebraic Thinking Proficiency And The Questions They Pose During Diagnostic Algebraic Thinking Interviews, Leigh A. Van Den Kieboom, Marta T. Magiera, John C. Moyer

Mathematics, Statistics and Computer Science Faculty Research and Publications

In this study, we explored the relationship between prospective teachers’ algebraic thinking and the questions they posed during one-on-one diagnostic interviews that focused on investigating the algebraic thinking of middle school students. To do so, we evaluated prospective teachers’ algebraic thinking proficiency across 125 algebra-based tasks and we analyzed the characteristics of questions they posed during the interviews. We found that prospective teachers with lower algebraic thinking proficiency did not ask any probing questions. Instead, they either posed questions that simply accepted and affirmed student responses or posed questions that guided the students toward an answer without probing student thinking. …

Relatively Congruence-Free Regular Semigroups, Peter R. Jones

Mathematics, Statistics and Computer Science Faculty Research and Publications

Yu, Wang, Wu and Ye call a semigroup S τ -congruence-free, where τ is an equivalence relation on S, if any congruence ρ on S is either disjoint from τ or contains τ . A congruence-free semigroup is then just an ω-congruence-free semigroup, where ω is the universal relation. They determined the completely regular semigroups that are τ -congruence-free with respect to each of the Green’s relations. The goal of this paper is to extend their results to all regular semigroups. Such a semigroup is J –congruence-free if and only if it is either a semilattice or has …

Generalized Exponentiated Moment Exponential Distribution, Zafar Iqbal, Syed Anwer Hasnain, Muhammad Salman, Munir Ahmad, Gholamhossein Hamedani

Mathematics, Statistics and Computer Science Faculty Research and Publications

Moment distributions have a vital role in mathematics and statistics, in particular in probability theory, in the perspective research related to ecology, reliability, biomedical field, econometrics, survey sampling and in life-testing. Hasnain (2013) developed an exponentiated moment exponential (EME) distribution and discussed some of its important properties. In the present work, we propose a generalization of EME distribution which we call it generalized EME (GEME) distribution and develop various properties of the distribution. We also present characterizations of the distribution in terms of conditional expectation as well as based on hazard function of the GEME random variable.

Some Remarks On Recent Characterizations Of Continuous Distributions, Gholamhossein Hamedani

Mathematics, Statistics and Computer Science Faculty Research and Publications

We would closely look at two recent published papers dealing with characterizations of certain univariate continuous distributions. We shall explain that the main results reported lack important assumptions. These results nevertheless are based on the conditional expectations of monotone functions of the generalized order statistics. We will also mention that similar results have recently been reported without the assumption of monotonicity of the functions of the generalized order statistics.

Anisotropic Magnetoresistance In Antiferromagnetic Sr2Iro4, C. Wang, H. Seinige, Gang Cao, J.-S. Zhou, J. B. Goodenough, M. Tsoi

Physics and Astronomy Faculty Publications

We report point-contact measurements of anisotropic magnetoresistance (AMR) in a single crystal of antiferromagnetic Mott insulator Sr₂IrO₄. The point-contact technique is used here as a local probe of magnetotransport properties on the nanoscale. The measurements at liquid nitrogen temperature reveal negative magnetoresistances (up to 28%) for modest magnetic fields (250 mT) applied within the IrO₂ a−b plane and electric currents flowing perpendicular to the plane. The angular dependence of magnetoresistance shows a crossover from fourfold to twofold symmetry in response to an increasing magnetic field with angular variations in resistance from 1% to 14%. We …

The Effect Of High School Athletics On Academics Success For Students From Disadvantaged Backgrounds, Gregory S. Daniels Jr

Capstone Projects and Master's Theses

Current research continues to explore the effects high school team sports have on student achievement. This study examined the connection between academic performance and team sports for Black high school students as well as for students from various ethnically diverse groups who, for the purpose of this analysis, are considered to be from backgrounds that are considered to be socio-economically disadvantaged. The study examined whether a well-coordinated study hall provided a foundation for self-regulation of academic task completion along with key responsibilities associated with skills for school success, such as school attendance, classroom behavior, and self-efficacy as mandated by the …

Controlling Survey Response Error In A Mail Survey Of Dairy Farmers: A Case Report, Julia M. Smith

Journal of Extension

Survey results are often presented with minimal description of how survey error was controlled. The objective of this article is to help survey developers and survey data interpreters (1) better understand the sources of survey error and (2) consider these sources of error when developing or reading a description of a survey's methodology. The subject of this article is a survey mailed to Vermont dairy farmers to assess farm characteristics relevant to the potential spread of disease among farms. Sources of error and how they were addressed in this survey are presented.

Bridging Formal And Informal Learning Environments, Bradley S. Barker, Kim Larson, Michelle Krehbiel

Journal of Extension

Out-of-school time programs that provide science, technology, engineering, and mathematics (STEM) educational content are promising approaches to develop skills and abilities in students. These programs may potentially inspire students with engaging hands-on, minds-on activities that encourages their natural curiosity around STEM content areas. However, it is also important to align out-of-school time learning activities with what is being taught in the formal classroom so that the experiences are congruent. Two examples of congruent programs are described in this article.

Current Status And Long-Term Trends In Water Quality And Living Resources In The Virginia Tributaries And Chesapeake Bay Mainstem From 1985 Through 2013, Daniel M. Dauer, Todd A. Egerton, John R. Donat, Michael F. Lane, Suzanne C. Doughten, Cindy Johnson, Monika Arora

Status and Trends for Virginia Chesapeake Bay

The period prior to the implementation of the Chesapeake Bay Monitoring Program was characterized by a marked decline in the water quality of the Chesapeake Bay. The disappearance of submerged aquatic vegetation in certain regions of the Bay, declines in the abundance of some commercially and recreationally important species, increases in the incidence of low dissolved oxygen events, changes in the Bay's food web, and other ecological problems have been related to the deteriorating water quality (e.g. USEPA, 1982,1983;Officer et al.,1984; Orth and Moore, 1984). The results of concentrated research efforts in the late 1970s and early 1980s stimulated the …

Line Lists For The A2Π-X 2Σ+ (Red) And B2Σ+-X 2Σ+ (Violet) Systems Of Cn, 13c14n, And 12c15n, And Application To Astronomicalspectra, Christopher Sneden, Sara Lucatello, Ram S. Ram, James S. A. Brooke, Peter Bernath

Chemistry & Biochemistry Faculty Publications

New red and violet system line lists for the CN isotopologues ¹³C¹⁴N and ¹²C¹⁵N have been generated. These new transition data are combined with those previously derived for ¹²C¹⁴N, and applied to the determination of CNO abundances in the solar photosphere and in four red giant stars: Arcturus, the bright, very low-metallicity star HD 122563, and the carbon-enhanced metal-poor stars HD 196944 and HD 201626. When both red and violet system lines are detectable in a star, their derived N abundances are in good agreement. The mean N abundances determined in …

Can Analyzing Spatial Relationships Through Geographically Weighted Regression Improve Our Understanding Of Low School Attainment? A Gis-Based Analysis Of Census And Acs Data, William England

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

In this study I present a relatively new technique for analyzing a recurring problem in our communities. Using a set of innovative and relatively new modeling methods, I demonstrate ways in which it is possible to directly account for, capture, and visualize the spatial variability in the relationships between U.S. Census data from 1990 and the recent low-school-attainment landscape in both the Omaha and Lincoln Public School (OPS) districts in Omaha and Lincoln, NE. Low school attainment in adults is a correlate of a host of troubling health and economic factors, which, in turn, have an impact on a child's …

Changing Times: Population Movements And Education Quality, Nicholas J. Cordonier

Department of Political Science: Dissertations, Theses, and Student Research

This research aims to examine the relationship between population change and college readiness in Nebraska. Nebraska as well as three counties: Box Butte County, Lancaster County, and Scotts Bluff County were used as locations for this study. The process for analyzing the relationship is done in three parts. First, data was collected from the Nebraska Department of Education about high school variables such as teacher characteristics and attendance rates. Next, U.S. Census Bureau data was used to create socio-economic standards for the various locations. Finally, the high school variables and socio-economic standards were compared to several college readiness indicators to …

Applications Of Novel Mri Technologies In Tissue Engineering And Disease Diagnosis, Vahid Khalilzad-Sharghi

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Magnetic resonance imaging (MRI) and magnetic resonance elastography (MRE) are increasingly under investigation to explore their potential role in establishing effective evaluation methods for the procedure of tissue regeneration carried out in vitro, in vivo, and in disease diagnosis. To this end, there is a continuous pursuit of novel tools both in vitro and in vivo. For instance, there is a great need for the development and evaluation of an MR-compatible incubation system that enables simultaneous monitoring and culturing of cell and tissue constructs using MRI techniques. Such an imagingcompatible incubation system eliminates exposing the culture to the risks of …

Syntheses Of Aminyl Diradicals And Nitroxide Tetra- And Octaradicals, Arnon Olankitwanit

Department of Chemistry: Dissertations, Theses, and Student Research

This dissertation comprises of two main research projects: aminyl diradicals and calix[4]arene nitroxide tetra- and octaradicals. The design, multi-step synthesis and characterization, including NMR, EPR spectroscopy, magnetic measurements and X-ray crystallography of precursors and target compounds will be discussed.

Aminyl radicals, nitrogen-centered radicals, are typically short-lived and considered as reactive intermediates. Because of their unique magnetic properties, aminyls are attractive building blocks for high-spin di-and polyradicals. The challenge is in the design and synthesis of aminyls with increased stability. In this chapter, we have prepared triplet (S = 1) ground state aminyl diradicals, which are derivatives of aza-m …

An Algorithmic Approach To The Differential Galois Theory Of Second-Order Linear Differential Equations With Differential Parameters, Carlos Eduardo Arreche Aguayo

Dissertations, Theses, and Capstone Projects

We present algorithms to compute the differential Galois group G associated via the parameterized Picard-Vessiot theory to a parameterized second-order linear differential equation with respect to d/dx, with coefficients in the field of rational functions F(x) over a differential field F, where we think of the derivations on F as being derivations with respect to parameters. We build on an earlier procedure, developed by Dreyfus, that computes G when the equation is unimodular, assuming either that G is reductive, or else that its maximal reductive quotient is differentially constant. We first show how to modify the space of parametric derivations …

Paleoecology Of Late Cretaceous Methane Cold-Seeps Of The Pierre Shale, South Dakota, Kimberly Cynthia Handle

Dissertations, Theses, and Capstone Projects

Most investigations of ancient methane seeps focus on either the geologic or paleontological aspects of these extreme environments. In contrast, this thesis encompasses both disciplines to evaluate the paleoecology of these systems with greater detail than previously published either within the Western Interior Basin or elsewhere. This thesis addresses the following questions: 1) Are the changes in mineralogy of a seep discernable and predictable as a seep shifts from a clay-based environment to a carbonate-based environment? 2) What are the foundation organism(s) of Late Cretaceous methane cold-seeps? 3) Is there a correlation to the mineralogic changes and shifts in community …

Oxocarbenium Ion And Alkene Metathesis Strategies For The Synthesis Of Complex Cyclohexanes, Clayton Errol Mattis

Dissertations, Theses, and Capstone Projects

Highly oxygenated cyclohexanes comprise the structures of a number of pharmacologically interesting molecules, including potently bioactive natural products and carbapyranosides. The latter, which are unnatural analogues of carbohydrates in which the ring oxygen of the parent sugar is replaced with a methylene group, have attracted interest as hydrolytically stable mimetics of their parent O-glycosides. This research reports the development of two general methodologies for the synthesis of highly oxygenated cyclohexanes: (1) Oxocarbenium Ion Cyclization (OCC) and (2) Ring Closing Metathasis (RCM).

Chapter one gives a review of the literature on the synthesis for highly oxygenated cyclohexanes.

Spatial And Temporal Characteristics Of Polarimetric Tornadic Debris Signatures, Matthew S. Van Den Broeke, Sabrina T. Jauernic

Department of Earth and Atmospheric Sciences: Faculty Publications

Nonmeteorological scatter, including debris lofted by tornadoes, may be detected using the polarimetric radar variables. For the 17 months from January 2012 to May 2013, radar data were examined for each tornado reported in the domain of an operational polarimetric Weather Surveillance Radar-1988 Doppler (WSR-88D). Characteristics of the tornadic debris signature (TDS) were recorded when a signature was present. Approximately 16% of all tornadoes reported in Storm Data were associated with a debris signature, and this proportion is shown to vary regionally. Signatures were more frequently seen with tornadoes that were rated higher on the enhanced Fujita (EF) scale, with …

The Flipped Classroom: Its Effect On Student Academic Achievement And Critical Thinking Skills In High School Mathematics, Joranna Saunders

Doctoral Dissertations and Projects

This study examined the effect of the flipped classroom on academic achievement in high school mathematics. The purpose of this study was twofold. The immediate purpose was to determine if there was a statistical difference in student academic achievement in two high school mathematics classrooms once the flipped classroom concept was implemented. This study also examined the effect of the flipped classroom on students' critical thinking skills. This static-group comparison utilized a pretest-posttest non-equivalent control group design and two null hypotheses were tested. The flipped curriculum was not a significant factor in increasing student academic achievement or in increasing student …

The Effects Of A Seventh Grade Mathematics Remediation Course On Student Achievement, Jason Nix

Doctoral Dissertations and Projects

Since the installment of the No Child Left Behind Act, schools have sought strategies to help students meet these academic requirements. Many middle schools have turned to math remediation classes as a way to improve students' achievement scores. The purpose of this quantitative causal-comparative study was to explore the relationship of the mathematics remediation class as an intervention strategy to help low performing seventh grade students' achievement on the Georgia Criterion-Referenced Competency Test. The sample consisted of N= 775 (391 male, 384 female) seventh grade students enrolled in one rural middle school. The result of the statistical test, ANCOVA, revealed …
