Preservice Teachers’ Motivation, Sense Of Teaching Efficacy, And Expectation Of Reality Shock, Hyunjin Kim, Yoonjung Cho

Human Development and Family Science Faculty Publications

The present study investigated how pre-service teachers’ motivation and their sense of teaching efficacy influence their expectation about reality shock during the first year of professional teaching. A total of 533 pre-service teachers at a state university in the US Midwest participated in this study. The results showed that the pre-service teachers’ expectation of reality shock was negatively related to teacher efficacy and intrinsic motivation while it was positively related to introjected and external motivation. The results of a hierarchical regression analysis revealed that pre-service teachers’ sense of efficacy and introjected motivation were strong predictors of their expectation of reality …

Predictive Modeling Of Coupled Multi-Physics Systems: Ii. Illustrative Application To Reactor Physics, Dan Gabriel Cacuci, Madalina Corina Badea

Faculty Publications

This work presents paradigm applications to reactor physics of the innovative mathematical methodology for "predictive modeling of coupled multi-physics systems (PMCMPS)" developed by Cacuci (2014). This methodology enables the assimilation of experimental and computational information and computes optimally predicted responses and model parameters with reduced predicted uncertainties, taking fully into account the coupling terms between the multi-physics systems, but using only the computational resources that would be needed to perform predictive modeling on each system separately. The paradigm examples presented in this work are based on a simple neutron diffusion model, chosen so as to enable closed-form solutions with clear …

Comparison Of Instrumentation To Measure Air And Soil-Surface Temperature Variability In Northern Alaska, Katrina Keleher

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The Circumpolar Active Layer Monitoring (CALM) project has been observing permafrost (perennially frozen ground) and its overlaying active layer (which freezes and thaws annually) in northern Alaska’s Kuparuk River watershed and throughout the polar regions since the mid 1990’s to detect long-term responses to climatic change. The soil-surface temperature data is collected by thermistors that were positioned immediately below the surface of the ground at nine locations within a transect of 1-ha plots arranged from north to south across the region. Locations within each plot were individually selected to represent a full range of microsite conditions, with distinctions in vegetation, …

Disentangling The Effects Of Student Attitudes And Behaviors On Academic Performance, Susan Janssen, Maureen O'Brien

International Journal for the Scholarship of Teaching & Learning

The interplay among motivation, ability, attitudes, behaviors, homework, and learning is unclear from previous research. We analyze data collected from 687 students enrolled in seven economics courses. A model explaining homework and exam scores is estimated, and separate analyses of ability and motivation groups are conducted. We find that motivation and ability explain variation in both homework and exam scores. Attitudes and behaviors, such as procrastination and working with others directly, affect homework score, but not exam score. These effects are not the same within all motivation and ability groups. Given that homework is the strongest predictor of exam score, …

Ord Project: Groundwater Management Plan 2014, Stratagen, Landcorp

Irrigated Agricultural Development in the North

The Western Australian Minister for State Development is developing an area of land on the Weaber Plain for irrigated agriculture, approximately 30 km north-northeast of Kununurra and adjoining the existing Ord River Irrigation Area, in the Kimberley region of Western Australia. Key components or environmental aspects of the project relevant to groundwater management include:

• application of 80 – 120 GL/yr of irrigation water which would increase recharge over the Weaber Plain and add to any rise in the watertable

• vegetation clearing of approximately 9260 ha of land for farms and infrastructure which would increase groundwater recharge and result …

Reimagining The Synthesis Of Latino Youth In The Science Lab : Using Latino Cultural Identity To Teach Cellular Permeability, Nathalie Iturburua

Capstone Projects and Master's Theses

Academic excellence is often thought of as achieved through “motivation”. I use this term lightly because of its many definitions and lack of true value to its meaning in correlation with my project. Institutions often analyze student academics through the scope of the student. That is, completing homework assignments, preparing for tests and quizzes, spending adequate time outside of the classroom practicing academic integrity, staying out of the principal’s office, and so forth. Seldom institutions have shifted their focus to critique their own faculty and curriculum to analyze student academic interest. It is through the work of the faculty member …

Integrating Rock Music In Elementary School Education, Andre Firme

Capstone Projects and Master's Theses

Though music education is declining in schools across the nation, the classrooms that still utilize it to enhance other subject matter have witnessed its benefits. However, when the opportunity arises to integrate music into everyday lessons teaching core subjects, which genres should be focused on? Since educators would not wish to waste time on music that does not appeal to children’s listening preferences and knowing that weaving music in the educational fabric of the day teaches more effectively and efficiently, their preferred genre must be employed when the chance to integrate music, rare as it is, presents itself. Rock music …

Convolution Reverb & Impulse Responses, Sam Kantorik

Capstone Projects and Master's Theses

Convolution reverb is software that allows the user to emulate the specific acoustic characteristics of a real space. This is achieved by first taking an impulse response of the desired space. An impulse response is captured by amplifying a sine wave sweep into the space using high fidelity speakers, and then recording how that sweep is affected by the space using a microphone. Convolution reverb software can take the results of an impulse response and apply them to any other signal. In much simpler terms, convolution reverb allows the user to make any piece of prerecorded audio sound as if …

Evaluation Of A Conceptual Model Of Student Retention At A Public Urban Commuter University, Hoa Khuong

Dissertations

A new conceptual model of student retention was developed and evaluated for first-year retention and for second-year retention of students at an urban, mid-western commuter university. The model captured the joint effects of academic engagement and environmental factors on academic performance and persistence of commuter students in their first two years of college attendance. The academic engagement and environmental factors incorporated into the model included: pre-college academic achievement, Deep Learning, Study Time per Week, College Math Readiness, Major Selection, Hours of Employment, receiving (or not receiving) a Pell Grant Award and Financial Concerns. Structural equation modeling techniques were utilized to …

Quantum Non-Locality Vs. Quasi-Local Measurement In The Conditions Of The Aharonov-Bohm Effect, Armen Gulian

Mathematics, Physics, and Computer Science Faculty Articles and Research

Theoretical explanation of the Meissner effect involves proportionality between current density and vector potential, which has many deep consequences. As noticed by de Gennes, superconductors in a magnetic field "find an equilibrium state where the sum of kinetic and magnetic energies is minimum" and this state "corresponds to the expulsion of the magnetic field". This statement still leaves an open question: from which source is the superconducting current acquiring its kinetic energy? A naïve answer, perhaps, is from the energy of the magnetic field. However, one can consider situations (Aharonov-Bohm effect), where the classical magnetic field is locally absent in …

Foundations And Applications Of Weak Quantum Measurements, Yakir Aharonov, Eliahu Cohen, Avshalom C. Elitzur

Mathematics, Physics, and Computer Science Faculty Articles and Research

Weak quantum measurement (WM) is unique in measuring noncommuting operators and other peculiar, otherwise-undetectable phenomena predicted by the two-state-vector-formalism (TSVF). The aim of this article is threefold: (i) introducing the foundations of WM and TSVF, (ii) studying temporal peculiarities predicted by TSVF and manifested by WM, and (iii) presenting applications of WM to single particles.

“I Felt Like A Superhero”: The Experience Of Responding To Drug Overdose Among Individuals Trained In Overdose Prevention, Karla D. Wagner, Peter J. Davidson, Ellen Iverson, Rachel Washburn, Emily Burke, Alex H. Kral, Miles Mcneeley, Jennifer Jackson Bloom, Stephen E. Lankenau

Sociology Faculty Works

BACKGROUND: Overdose prevention programs (OPPs) train people who inject drugs and other community members to prevent, recognise and respond to opioid overdose. However, little is known about the experience of taking up the role of an "overdose responder" for the participants.

METHODS: We present findings from qualitative interviews with 30 participants from two OPPs in Los Angeles, CA, USA from 2010 to 2011 who had responded to at least one overdose since being trained in overdose prevention and response.

RESULTS: Being trained by an OPP and responding to overdoses had both positive and negative effects for trained "responders". Positive effects …

An Incremental Reseeding Strategy For Clustering, Xavier Bresson, Huiyi Hu, Thomas Laurent, Arthur Szlam, James Von Brecht

Mathematics, Statistics and Data Science Faculty Works

In this work we propose a simple and easily parallelizable algorithm for multiway graph partitioning. The algorithm alternates between three basic components: diffusing seed vertices over the graph, thresholding the diffused seeds, and then randomly reseeding the thresholded clusters. We demonstrate experimentally that the proper combination of these ingredients leads to an algorithm that achieves state-of-the-art performance in terms of cluster purity on standard benchmarks datasets. Moreover, the algorithm runs an order of magnitude faster than the other algorithms that achieve comparable results in terms of accuracy. We also describe a coarsen, cluster and refine approach similar to GRACLUS and …

Crossed Modules Of Racks, Alissa S. Crans, Friedrich Wagemann

Mathematics, Statistics and Data Science Faculty Works

We generalize the notion of a crossed module of groups to that of a crossed module of racks. We investigate the relation to categorified racks, namely strict 2-racks, and trunk-like objects in the category of racks, generalizing the relation between crossed modules of groups and strict 2-groups. Then we explore topological applications. We show that by applying the rack-space functor, a crossed module of racks gives rise to a covering. Our main result shows how the fundamental racks associated to links upstairs and downstairs in a covering fit together to form a crossed module of racks.

Complete Bipartite Graphs Whose Topological Symmetry Groups Are Polyhedral, Blake Mellor

Mathematics, Statistics and Data Science Faculty Works

We determine for which n, the complete bipartite graph K_n,n has an embedding in S³ whose topological symmetry group is isomorphic to one of the polyhedral groups: A₄, A₅, or S₄.

Robust Noise Attenuation Under Stochastic Noises And Worst-Case Unmodelled Dynamics, Araz Hashemi, Ben G. Fitzpatrick, Le Yi Wang, George Yin

Mathematics, Statistics and Data Science Faculty Works

This paper investigates noise attenuation problems for systems with unmodelled dynamics and unknown noise characteristics. A unique methodology is introduced that employs signal estimation in one phase, followed by control design for noise rejection. The methodology enjoys certain advantages in its simple control design process, accommodation of unmodelled dynamics, and non-conservative noise rejection performance. Under mild information on unmodelled dynamics, we first derive robust performance bounds on noise attenuation with respect to unmodelled dynamics without noise estimation errors. Then more general results are presented for systems that are subject to both stochastic signal estimation errors and unmodelled dynamics. Examples are …

Identification And Characterization Of Functionally Critical, Conserved Motifs In The Internal Repeats And N-Terminal Domain Of Yeast Translation Initiation Factor 4b (Yeif4b), Sarah F. Mitchell

Chemistry and Biochemistry Faculty Works

EIF4B has been implicated in attachment of the 43 S preinitiation complex (PIC) to mRNAs and scanning to the start codon. We recently determined that the internal seven repeats (of ∼26 amino acids each) of Saccharomyces cerevisiae eIF4B (yeIF4B) compose the region most critically required to enhance mRNA recruitment by 43 S PICs in vitro and stimulate general translation initiation in yeast. Moreover, although the N-terminal domain (NTD) of yeIF4B contributes to these activities, the RNA recognition motif is dispensable. We have now determined that only two of the seven internal repeats are sufficient for wildtype (WT) yeIF4B function in …

Structure And Dynamics Of The Hiv-1 Frameshift Element Rna, Kathryn Mouzakis

Chemistry and Biochemistry Faculty Works

The HIV-1 ribosomal frameshift element is highly structured, regulates translation of all virally encoded enzymes, and is a promising therapeutic target. The prior model for this motif contains two helices separated by a three-nucleotide bulge. Modifications to this model were suggested by SHAPE chemical probing of an entire HIV-1 RNA genome. Novel features of the SHAPE-directed model include alternate helical conformations and a larger, more complex structure. These structural elements also support the presence of a secondary frameshift site within the frameshift domain. Here, we use oligonucleotide-directed structure perturbation, probing in the presence of formamide, and in-virion experiments to examine …

Principles And Properties Of Eukaryotic Mrnps, Sarah F. Mitchell

Chemistry and Biochemistry Faculty Works

The proper processing, export, localization, translation, and degradation of mRNAs are necessary for regulation of gene expression. These processes are controlled by mRNA-specific regulatory proteins, noncoding RNAs, and core machineries common to most mRNAs. These factors bind the mRNA in large complexes known as messenger ribonucleoprotein particles (mRNPs). Herein, we review the components of mRNPs, how they assemble and rearrange, and how mRNP composition differentially affects mRNA biogenesis, function, and degradation. We also describe how properties of the mRNP "interactome" lead to emergent principles affecting the control of gene expression.

Β-Alanine Supplementation Improves Tactical Performance But Not Cognitive Function In Combat Soldiers, William Mccormack

Health and Human Sciences Faculty Works

Background: There are no known studies that have examined β-alanine supplementation in military personnel. Considering the physiological and potential neurological effects that have been reported during sustained military operations, it appears that β-alanine supplementation may have a potential benefit in maintaining physical and cognitive performance during high-intensity military activity under stressful conditions. The purpose of this study was to examine the effect of 28 days of β-alanine ingestion in military personnel while fatigued on physical and cognitive performance. Methods: Twenty soldiers (20.1 ± 0.9 years) from an elite combat unit were randomly assigned to either a β-alanine (BA) or placebo …

Hom Quandles, Alissa S. Crans, Sam Nelson

Mathematics, Statistics and Data Science Faculty Works

If A is an abelian quandle and Q is a quandle, the hom set Hom(Q,A) of quandle homomorphisms from Q to A has a natural quandle structure. We exploit this fact to enhance the quandle counting invariant, providing an example of links with the same counting invariant values but distinguished by the hom quandle structure. We generalize the result to the case of biquandles, collect observations and results about abelian quandles and the hom quandle, and show that the category of abelian quandles is symmetric monoidal closed.

Simulation Of The Sampling Distribution Of The Mean Can Mislead, Ann E. Watkins, Anna E. Bargagliotti, Christine Franklin

Mathematics, Statistics and Data Science Faculty Works

Although the use of simulation to teach the sampling distribution of the mean is meant to provide students with sound conceptual understanding, it may lead them astray. We discuss a misunderstanding that can be introduced or reinforced when students who intuitively understand that “bigger samples are better” conduct a simulation to explore the effect of sample size on the properties of the sampling distribution of the mean. From observing the patterns in a typical series of simulated sampling distributions constructed with increasing sample sizes, students reasonably—but incorrectly—conclude that, as the sample size, n, increases, the mean of the (exact) sampling …

The Motion Of Intellect On The Neoplatonic Reading Of Sophist 248e-249d, Eric D. Perl

Philosophy Faculty Works

This paper defends Plotinus’ reading of Sophist 248e-249d as an expression of the togetherness or unity-in-duality of intellect and intelligible being. Throughout the dialogues Plato consistently presents knowledge as a togetherness of knower and known, expressing this through the myth of recollection and through metaphors of grasping, eating, and sexual union. He indicates that an intelligible paradigm is in the thought that apprehends it, and regularly regards the forms not as extrinsic “objects” but as the contents of living intelligence. A meticulous reading of Sophist 248e-249d shows that the “motion” attributed to intelligible being is not temporal change but the …
