Incorporating Critical Thinking: Self-Perception Of Teachers’ Ability To Promote Critical Thinking Skills In Primary Grades (K-2), Courtney Milligan

Dissertations

The ability to think critically is a fundamental life skill and is an essential part of being a productive and contributing member of society. “Research shows that elements of critical thinking need to be taught explicitly” (Haber, 2020). The practice of developing critical thinking skills while students are initially "developing as thinkers" in primary grades is essential. According to Wagner (2008), his research finds that children should begin developing critical thinking skills as soon as they “are capable of abstract thinking” (p.17). Wagner (2008) argues that students need to develop these essential skills to effectively participate in our democracy and …

Transfer-To-Transfer Learning Approach For Computer Aided Detection Of Covid-19 In Chest Radiographs, Barath Narayanan Narayanan, Russell C. Hardie, Vignesh Krishnaraja, Christina Karam, Venkata Salini Priyamvada Davuluru

Electrical and Computer Engineering Faculty Publications

The coronavirus disease 2019 (COVID-19) global pandemic has severely impacted lives across the globe. Respiratory disorders in COVID-19 patients are caused by lung opacities similar to viral pneumonia. A Computer-Aided Detection (CAD) system for the detection of COVID-19 using chest radiographs would provide a second opinion for radiologists. For this research, we utilize publicly available datasets that have been marked by radiologists into two-classes (COVID-19 and non-COVID-19). We address the class imbalance problem associated with the training dataset by proposing a novel transfer-to-transfer learning approach, where we break a highly imbalanced training dataset into a group of balanced mini-sets and …

Polarization-Selective Modulation Of Supercavity Resonances Originating From Bound States In The Continuum, Chan Kyaw, Riad Yahiaoui, Joshua A. Burrow, Viet Tran, Kyron Keelen, Wesley Sims, Eddie C. Red, Willie S. Rockward, Mikkel A. Thomas, Andrew M. Sarangan, Imad Agha, Thomas A. Searles

Electro-Optics and Photonics Faculty Publications

Bound states in the continuum (BICs) are widely studied for their ability to confine light, produce sharp resonances for sensing applications and serve as avenues for lasing action with topological characteristics. Primarily, the formation of BICs in periodic photonic band gap structures are driven by symmetry incompatibility; structural manipulation or variation of incidence angle from incoming light. In this work, we report two modalities for driving the formation of BICs in terahertz metasurfaces. At normal incidence, we experimentally confirm polarization driven symmetry-protected BICs by the variation of the linear polarization state of light. In addition, we demonstrate through strong coupling …

A Qualitative Study Of Differences Among Hearing Parents In Positive Experiences Raising A Deaf Child: An Emergent Model Informed By Positive Psychology​, Amy Szarkowski, Patrick J. Brice

JADARA

The current qualitative study explored the positive, internal, and growth-enhancing experiences hearing parents derived from raising a child who is deaf or hard of hearing. Based on characteristics of parents’ process and outcomes of the parenting experiences, three distinct parent patterns were identified. Reflective Positive Parents reflected deeply about their experiences, quickly and easily identified positive experiences, and were open to making adjustments to meet their child’s needs. Engaged Parents contemplated their experiences, yet decisions about how to best support their children in many remained unresolved; this group identified both positive and negative aspects of parenting and attempted to align …

Green Prescriptions – Prescribing Lifestyle Modification To Combat A Silent Pandemic., Jonathan Guajardo

MEDI 9331 Scholarly Activities Clinical Years

Obesity is a well-known modifiable risk factor that contributes to the development of atherosclerosis. In the Rio Grande Valley, a region located in southern Texas, the rate of obesity rises to 47%, compared to 44% in the US. [4] Obesity is largely driven by poor diet and lack of physical activity and poor compliance/adherence to dietary and physical activity recommendations. [4] We seek to gauge the effect of green prescriptions, prescribed lifestyle modification, on compliance in the RGV population. Selected patients will receive a pre- and post-survey for subjective measures and be given a workout regimen according to exercise history. …

Sensory Approach To Self-Regulation For Adolescent Survivors Of Sex Trafficking: An Occupational Therapist's Perspective, Elyse Harmon

Student Capstone Papers

Adolescent survivors of sex trafficking (SST) are susceptible to being in a continual dysregulated arousal state due to lack of mastery in self-regulation. During the trafficking experience, many adolescent SST experience severe trauma and are deprived of opportunities that foster essential regulatory capacities needed for occupational engagement. The use of sensory-based approaches that focus on addressing arousal dysregulation and the impact it has on occupation is an evidence-based practice grounded in occupational therapy research.

This capstone sought to support community reintegration for adolescent SST through the development of sensory-based programming that fosters self-regulation, a skill necessary for occupational participation. A …

Emotional Presence In Building An Online Learning Community Among Non-Traditional Graduate Students, Mei Jiang, Katie Koo

Faculty Publications

The Community of Inquiry (CoI) framework posits that a collaborative online teaching and learning process can be achieved through three interdependent dimensions of presence: cognitive presence, social presence, and teaching presence. Emotion is considered an important factor in successful online learning. This study explored non-traditional graduate students’ perceived emotional presence that emerged in participants’ online learning experiences. Based on quantitative and qualitative data from 45 non-traditional graduate students in the field of education, the study showed that participants demonstrated both positive emotional expressions (e.g., enjoyment and happiness) and negative expressions (e.g., frustration and disappointment) in their responses. Emotional presence ratings …

Envrment: Investigating Experience In A Virtual User-Composed Environment, Matthew Key

Master's Theses

Virtual Reality is a technology that has long held society's interest, but has only recently began to reach a critical mass of everyday consumers. The idea of modern VR can be traced back decades, but because of the limitations of the technology (both hardware and software), we are only now exploring its potential. At present, VR can be used for tele-surgery, PTSD therapy, social training, professional meetings, conferences, and much more. It is no longer just an expensive gimmick to go on a momentary field trip; it is a tool, and as with the automobile, personal computer, and smartphone, it …

Real-Time Body Tracking And Projection Mapping In The Interactive Arts, Sydney Baroya

Master's Theses

Projection mapping, a subtopic of augmented reality, displays computer-generated light visualizations from projectors onto the real environment. A challenge for projection mapping in performing interactive arts is dynamic body movements. Accuracy and speed are key components for an immersive application of body projection mapping and dependent on scanning and processing time.

This thesis presents a novel technique to achieve real-time body projection mapping utilizing a state of the art body tracking device, Microsoft’s Azure Kinect DK, by using an array of trackers for error minimization and movement prediction. The device's Sensor and Bodytracking SDKs allow multiple device synchronization. We combine …

Design And Validation Of An Led-Based Solar Simulator For Solar Cell And Thermal Testing, Matthew Gunther

Master's Theses

An LED-based solar simulator has been designed, constructed, and qualified under ASTM standards for use in the Cal Poly Space Environments Laboratory. The availability of this simulator will enhance the capability of undergraduate students to evaluate solar cell and thermal coating performance, and offers further research opportunities. The requirements of ASTM E927-19 for solar simulators intended for photovoltaic cell testing were used primarily, supplemented by information from ASTM E491-73 for solar simulators intended for spacecraft thermal vacuum testing. Three main criteria were identified as design goals - spectral match ratio, spatial non-uniformity, and temporal instability. An electrical design for an …

The European Union And Violence Against Women: Fundamental Rights And Con Games, R. Amy Elman

Dignity: A Journal of Analysis of Exploitation and Violence

Deciphering the European Union’s (EU) commitment to countering violence against women is challenging. To date, much of its response has been rhetorical. This article opens with a brief consideration of the EU’s first few initiatives to counter violence against women before turning to the polity’s enthusiastic endorsement of the Council of Europe’s 2011 Istanbul Convention, which defines such violence as a human rights violation. Not least, it offers a critical analysis of the EU’s Fundamental Rights Agency’s 2014 survey on violence against women, the world’s largest international survey of its kind. That inquiry involved 42,000 in-person interviews with a representative …

Throwing Off The Corset: A Contemporary History Of The Beauty Resistance Movement In South Korea, Hyejung Park

Dignity: A Journal of Analysis of Exploitation and Violence

The tal-corset movement, a beauty resistance campaign, swept South Korea’s feminist scene in 2018 and became a phenomenon bringing about unprecedented social changes in South Korea. This article explains sociocultural contexts to South Korea’s tal-corset movement through group interviews and examination of online materials. It documents the contemporary history of the development of the movement from a feminist perspective. Findings show that movement participants see beauty practice as social oppression imposed on women’s bodies and appearances and the marker of women’s low social status. The new wave of an online feminist movement that emerged in 2015 created women-only communities that …

Taxes As Pandemic Controls, Ashley C. Craig, James R. Hines Jr.

Articles

Tax policy can play important roles in limiting the spread of communicable disease and in managing the economic fallout of a pandemic. Taxes on business activities that bring workers or customers into close contact with each other offer efficient alternatives to broad regulatory measures, such as shutdowns, that have been effective but enormously costly. Corrective taxation also helps raise the revenue required to cover elevated government expenditure during a pandemic. Moreover, the restricted consumer choice that accompanies a pandemic reduces the welfare cost of raising tax revenue from higher-income taxpayers, making it a good time for deficit closure. Current U.S. …

On A Multiserver Queueing System With Customers’ Impatience Until The End Of Service Under Single And Multiple Vacation Policies, Mokhtar Kadi, Amina A. Bouchentouf, Lahcene Yahiaoui

Applications and Applied Mathematics: An International Journal (AAM)

This paper deals with a multiserver queueing system with Bernoulli feedback and impatient customers (balking and reneging) under synchronous multiple and single vacation policies. Reneged customers may be retained in the system. Using probability generating functions (PGFs) technique, we formally obtain the steady-state solution of the proposed queueing system. Further, important performance measures and cost model are derived. Finally, numerical examples are presented.

The Linear Combination Of Kernels In The Estimation Of Cumulative Distribution Functions, Abdel-Razzaq Mugdadi, Rugayyah Sani

Applications and Applied Mathematics: An International Journal (AAM)

The kernel distribution function estimator method is the most popular nonparametric method to estimate the cumulative distribution function F(x). In this investigation, we propose a new estimator for F(x) based on a linear combination of kernels. The mean integrated squared error, asymptotic mean integrated squared error and the asymptotically optimal bandwidth for the new estimator are derived. Also, based on the plug-in technique in density estimation, we propose a data based method to select the bandwidth for the new estimator. In addition, we evaluate the new estimator using simulations and real life data.

Estimating Parameter Of The Selected Uniform Population Under The Generalized Stein Loss Function, K. R. Meena, Aditi K. Gangopadhyay

Applications and Applied Mathematics: An International Journal (AAM)

This paper deals with the problem of estimating scale parameter of the selected uniform population when sample sizes are unequal. The loss has been measured by the generalized Stein loss (GSL) function. The uniformly minimum risk unbiased (UMRU) estimator is derived, and the natural estimators are also constructed under the GSL function. One of the natural estimators is proved to be the generalized Bayes estimator with respect to a noninformative prior. For k = 2, we obtained a sufficient condition for an inadmissibility result and demonstrate that the natural estimator and UMRU estimator are inadmissible. A simulation investigation is also …

Fuzzy Solutions To Second Order Three Point Boundary Value Problem, Dimplekumar N. Chalishajar, R. Ramesh

Applications and Applied Mathematics: An International Journal (AAM)

In this manuscript, the proposed work is to study the existence of second-order differential equations with three point boundary conditions. Existence is proved using fuzzy set valued mappings of a real variable whose values are normal, convex, upper semi continuous and compactly supported fuzzy sets. The sufficient conditions are also provided to establish the existence results of fuzzy solutions of second order differential equations for three point boundary value problem. By using Banach fixed point principle, a new existence theorem of solutions for these equations in the metric space of normal fuzzy convex sets with distance given by the maximum …

Heat And Mass Transfer In Micropolar Model For Blood Flow Through A Stenotic Tapered Artery, Moses S. Dada, Funmilola Alamu-Awoniran

Applications and Applied Mathematics: An International Journal (AAM)

Heat and mass transfer in blood flow through a tapered artery with mild stenosis is examined. The blood is considered to be an incompressible, micropolar fluid flowing through a vessel with nonsymmetric axial and symmetric radial axes. The geometry of the model takes into account the shape parameter, tapered angle and height of the stenosis.The variation in the shape parameter is used to describe the changes in the axial shape of the stenosis in the artery. The governing equations for the model, comprising the continuity, momentum, energy, and mass transfer equations are transformed and simplified under the assumption of mild …

Controlling And Synchronizing Combined Effect Of Chaos Generated In Generalized Lotka-Volterra Three Species Biological Model Using Active Control Design, Taqseer Khan, Harindri Chaudhary

Applications and Applied Mathematics: An International Journal (AAM)

In this work, we study hybrid projective combination synchronization scheme among identical chaotic generalized Lotka-Volterra three species biological systems using active control design. We consider here generalized Lotka-Volterra system containing two predators and one prey population existing in nature. An active control design is investigated which is essentially based on Lyapunov stability theory. The considered technique derives the global asymptotic stability using hybrid projective combination synchronization technique. In addition, the presented simulation outcomes and graphical results illustrate the validation of our proposed scheme. Prominently, both the analytical and computational results agree excellently. Comparisons versus others strategies exhibiting our proposed technique …

School of Medicine Publications

Cortical thickness, surface area and volumes vary with age and cognitive function, and in neurological and psychiatric diseases. Here we report heritability, genetic correlations and genome-wide associations of these cortical measures across the whole cortex, and in 34 anatomically predefined regions. Our discovery sample comprises 22,824 individuals from 20 cohorts within the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium and the UK Biobank. We identify genetic heterogeneity between cortical measures and brain regions, and 160 genome-wide significant associations pointing to wnt/β-catenin, TGF-β and sonic hedgehog pathways. There is enrichment for genes involved in anthropometric traits, hindbrain …

Proportional Voting Based Semi-Unsupervised Machine Learning Intrusion Detection System, Yang G. Kim, Ohbong Kwon, John Yoon

Publications and Research

Feature selection of NSL-KDD data set is usually done by finding co-relationships among features, irrespective of target prediction. We aim to determine the relationship between features and target goals to facilitate different target detection goals regardless of the correlated feature selection. The unbalanced data structure in NSL-KDD data can be relaxed by Proportional Representation (PR). However, adopting PR would deny the notion of winner-take-all by attracting a majority of the vote and also provide a fairly proportional share for any grouping of like-minded data. Furthermore, minorities and majorities would get a fair share of power and representation in data structure …

Who, What, Why & How: Reimagining State Constitutional Analysis In School Finance Litigation, William Thro

BYU Education & Law Journal

Despite the Supreme Court’s recognition of the importance of public education, America’s public schools remain ravaged by “savage inequalities”which lead to failure of the public schools.Because every State, except Hawaii, partially finances local public schools through local property taxes and because there are differences in the value of real property, there are vast disparities in available funding for local school districts. While every State Constitution requires the State Legislature to establish a public school system and while the State Legislatures have enacted a variety of statutes in an attempt to meet the state constitutional obligations, virtually every State has seen …

Complex Trauma In Childhood And Its Relationship To Emotion Regulation And Distress Tolerance In College Students, Elizabeth Lombardo

USC Aiken Psychology Theses

Objective: The influence of childhood trauma has been found to be related to difficulties in emotion regulation and distress tolerance in young adulthood (Berenz et al., 2018a, 2018b). Research has shown that childhood abuse and adversities such as neglect or emotional abuse results in impaired processes related to the development of emotion regulation and efficient interpersonal skills, while also resulting in symptoms reflecting disordered affective self-regulation (Cloitre et al., 2009; Shipman, Edwards, Brown, Swisher, & Jennings, 2005; Shipman, Zeman, Penza, & Champion, 2000). Research has examined emotional regulation and distress tolerance in the context of childhood trauma but has not …
