Benefits Of The Modern Classroom Project In High School Mathematics, Micah Josiah Smith

Theses and Dissertations--Education Sciences

Previous research has shown that mathematical self-efficacy is positively correlated with mathematical achievement. However, in a high school classroom setting, teachers’ effectiveness varies based on experience, education, and how they incorporate certain pedagogical practices. The Modern Classroom Project was designed to have teachers integrate self-paced learning, mastery-based learning, metacognition, and blended instructions all within one classroom; with an emphasis placed on allowing students the opportunity to understand a particular skill before attempting the next skill. Discovering what components of the Modern Classroom Project enhances student’s self-efficacy score, and mathematical achievement was the focus of the study.

The ESSA emphasizes the importance of preschool education; the act states that more resources will be devoted to preschool education, which lays the foundation for children’s school learning process. The goal of the act is to make sure children enter kindergarten education with equal preparatory. School, family, and researchers are paying more attention to developing preschool children’s social and emotional competency before entering Kindergarten. For understanding preschool children’s social and emotional skill development situation, instrument is the mostly widely adopted method …

Knitting Code: Examining The Relationship Between Knitting And Computational Thinking Skills Using The Nexus Of Practice, Emily Rose Dodson-Snowden

Theses and Dissertations--Education Sciences

Due to the rise of careers in STEM-related fields, there is a growing need for schools to produce people to fill these positions. One area of STEM that is growing is computer science/coding. Due to this demand, schools need to be intentional about exposing students to computer science/coding. There are a variety of new tools to introduce students to this field. One growing belief is that knitting can teach computer science/coding to students.

The goal of this study was to see if knitting can serve as an introduction to teach students computation skills. Kitting has historically been used to code …

Student Involvement & Growth: A Case Study On Student Stories Of Agency & Adulthood, Jamie Nicole Taylor

Theses and Dissertations--Educational Policy Studies and Evaluation

Often students face their most challenging life decisions and periods of growth during college. Engagement and involvement with their institution helps students develop socially and academically; some research shows that involvement can support other students’ needs as well. The goal of this project is to explore the ways in which students perceive their agency or sense of freedom of choice relative to their college engagement. Using multi-level data collection, consisting of a background recruitment survey and two interview sessions, the data generated in this layered approach came from the third-year student cohort at one state university in the southeastern US. …

Authorship & Agency: Exploring Coaching As A Tool For Student Success, Allison Rebecca Lake

Theses and Dissertations--Educational Policy Studies and Evaluation

Coaching has emerged as a new, innovative practice within higher education. However, we have only begun to understand the true impact of coaching for college students. Research from individual coaching programs has shown that students who participate in coaching sessions are more likely to be retained, have higher GPAs, and engage in self-regulated learning. However, little research has been done to explore coaching from the student perspective. We do not yet understand how students utilize coaching as a tool to optimize their student experience. The goal of this project was to explore how coaching impacts the student experience and to …

A Survey Of Elementary Educators' Self-Efficacy Related To Stem Education, Elizabeth Mckenzie Johnson

Theses and Dissertations--Science, Technology, Engineering, and Mathematics (STEM) Education

While the call for STEM and engineering design has increased since the release of the Next Generation Science Standards, the implementation of STEM in elementary grades has been slow. A variety of factors play a role in why educators, schools, or districts make the informed decisions they do regarding curriculum and instruction. Identifying strengths and challenges elementary educators face in implementing STEM into the curriculum can guide schools and districts in creating supports for increasing STEM in the elementary grades. This study sought to create and test a survey instrument for use with elementary educators in a large urban district …

Equivalence Of The Transition Heat Capacities Of Proteins And Dna, Matthew W. Eskew, Albert S. Benight

Chemistry Faculty Publications and Presentations

It has been reported for many globular proteins that the native heat capacity at 25°C, per gram, is the same. This has been interpreted to indicate that heat capacity is a fundamental property of native proteins that provides important information on molecular structure and stability. Heat capacities for both proteins and DNA has been suggested to be related to universal effects of hydration/solvation on native structures. Here we report on results from thermal denaturation analysis of two well-known proteins, human serum albumin and lysozyme, and a short DNA hairpin. The transition heat capacities at the Tm for the three molecules …

This paper presents a before and after analysis of the impact of posted speed limit (PSL) changes on passenger car (FHWA class two vehicles) speeds in Portland, OR. The study focuses on urban roads, comparing sites that underwent a PSL 5-mph reduction (treatment sites) and sites where the PSL did not change (control sites). Sites with a high percentage of and priority for cyclists (neighborhood greenways) and sites with a more standard traffic composition were compared. Differences in speed characteristics such as mean and 85th percentile speeds, the speed variance, and the proportion of vehicles exceeding a speed threshold (relative …

Compound Flooding In Convergent Estuaries: Insights From An Analytical Model, Ramin Familkhalili, Stefan A. Talke, David A. Jay

Civil and Environmental Engineering Faculty Publications and Presentations

We investigate here the effects of geometric properties (channel depth and cross-sectional convergence length), storm surge characteristics, friction, and river flow on the spatial and temporal variability of compound flooding along an idealized, meso-tidal coastal-plain estuary. An analytical model is developed that includes exponentially convergent geometry, tidal forcing, constant river flow, and a representation of storm surge as a combination of two sinusoidal waves. Nonlinear bed friction is treated using Chebyshev polynomials and trigonometric functions, and a multisegment approach is used to increase accuracy. Model results show that river discharge increases the damping of surge amplitudes in an estuary, while …

Evaluation Of Noise Regression Techniques In Resting-State Fmri Studies Using Data Of 434 Older Adults, Norman Scheel, Jeffrey N Keller, Ellen F Binder, Eric D Vidoni, Jeffrey M Burns, Binu P Thomas, Ann M Stowe, Linda S Hynan, Diana R Kerwin, Wanpen Vongpatanasin, Heidi Rossetti, C Munro Cullum, Rong Zhang, David C Zhu

2020-Current year OA Pubs

Subject motion is a well-known confound in resting-state functional MRI (rs-fMRI) and the analysis of functional connectivity. Consequently, several clean-up strategies have been established to minimize the impact of subject motion. Physiological signals in response to cardiac activity and respiration are also known to alter the apparent rs-fMRI connectivity. Comprehensive comparisons of common noise regression techniques showed that the "Independent Component Analysis based strategy for Automatic Removal of Motion Artifacts" (ICA-AROMA) was a preferred pre-processing technique for teenagers and adults. However, motion and physiological noise characteristics may differ substantially for older adults. Here, we present a comprehensive comparison of noise-regression …

Expansion Of A Novel Population Of Nk Cells With Low Ribosome Expression In Juvenile Dermatomyositis, Kinsey A Hilliard, Allison A Throm, Jeanette T Pingel, Nermina Saucier, Hani S Zaher, Anthony R French

2020-Current year OA Pubs

Juvenile dermatomyositis (JDM) is a pediatric autoimmune disease associated with characteristic rash and proximal muscle weakness. To gain insight into differential lymphocyte gene expression in JDM, peripheral blood mononuclear cells from 4 new-onset JDM patients and 4 healthy controls were sorted into highly enriched lymphocyte populations for RNAseq analysis. NK cells from JDM patients had substantially greater differentially expressed genes (273) than T (57) and B (33) cells. Upregulated genes were associated with the innate immune response and cell cycle, while downregulated genes were associated with decreased ribosomal RNA. Suppressed ribosomal RNA in JDM NK cells was validated by measuring …

Neonatal Motor Functional Connectivity And Motor Outcomes At Age Two Years In Very Preterm Children With And Without High-Grade Brain Injury, Peppar E P Cyr, Rachel E Lean, Jeanette K Kenley, Sydney Kaplan, Dominique E Meyer, Jeffery J Neil, Dimitrios Alexopoulos, Rebecca G Brady, Joshua S Shimony, Thomas L Rodebaugh, Cynthia E Rogers, Christopher D Smyser

2020-Current year OA Pubs

Preterm-born children have high rates of motor impairments, but mechanisms for early identification remain limited. We hypothesized that neonatal motor system functional connectivity (FC) would relate to motor outcomes at age two years; currently, this relationship is not yet well-described in very preterm (VPT; born <32 weeks' gestation) infants with and without brain injury. We recruited 107 VPT infants - including 55 with brain injury (grade III-IV intraventricular hemorrhage, cystic periventricular leukomalacia, post-hemorrhagic hydrocephalus) - and collected FC data at/near term-equivalent age (35-45 weeks postmenstrual age). Correlation coefficients were used to calculate the FC between bilateral motor and visual cortices and thalami. At two years corrected-age, motor outcomes were assessed with the Bayley Scales of Infant and Toddler Development, 3rd edition. Multiple imputation was used to estimate missing data, and regression models related FC measures to motor outcomes. Within the brain-injured group only, interhemispheric motor cortex FC was positively related to gross motor outcomes. Thalamocortical and visual FC were not related to motor scores. This suggests neonatal alterations in motor system FC may provide prognostic information about impairments in children with brain injury.

Identification And Management Of Aggressive Meningiomas, Bhuvic Patel, Rupen Desai, Sangami Pugazenthi, Omar H Butt, Jiayi Huang, Albert H Kim

2020-Current year OA Pubs

Meningiomas are common primary central nervous system tumors derived from the meninges, with management most frequently entailing serial monitoring or a combination of surgery and/or radiation therapy. Although often considered benign lesions, meningiomas can not only be surgically inaccessible but also exhibit aggressive growth and recurrence. In such cases, adjuvant radiation and systemic therapy may be required for tumor control. In this review, we briefly describe the current WHO grading scale for meningioma and provide demonstrative cases of treatment-resistant meningiomas. We also summarize frequently observed molecular abnormalities and their correlation with intracranial location and recurrence rate. We then describe how …

Metal Coordinating Inhibitors Of Rift Valley Fever Virus Replication, Elizabeth Geerling, Mohamed Elagawany, Bahaa Elgendy, Et Al

2020-Current year OA Pubs

Rift Valley fever virus (RVFV) is a veterinary and human pathogen and is an agent of bioterrorism concern. Currently, RVFV treatment is limited to supportive care, so new drugs to control RVFV infection are urgently needed. RVFV is a member of the order Bunyavirales, whose replication depends on the enzymatic activity of the viral L protein. Screening for RVFV inhibitors among compounds with divalent cation-coordinating motifs similar to known viral nuclease inhibitors identified 47 novel RVFV inhibitors with selective indexes from 1.1-103 and 50% effective concentrations of 1.2-56 μM in Vero cells, primarily α-Hydroxytropolones and N-Hydroxypyridinediones. Inhibitor activity and selective …

Verification Of Nand Flash Controller, M. J. Prajwala, Kush Desai, Lili He

Faculty Research, Scholarly, and Creative Activity

NAND structure-based Flash memory-made SSDs are turning more popular than HDDs in several applications notably in consumer microelectronics devices and enterprise memory storage devices. The NAND controller is the heart of this system. It acts as a bridge for communication between the host system (usually the Personal Computer system) and the NAND Flash memory storage device. Unarguably, it can be said that it is an essential part of the NAND flash-based memory device and it helps to manage the directory containing file systems. The controller is also accountable for managing system features like wear levelling, error code correction (through ECC), …

“Don't Downvote A$$$$$$S!!”: An Exploration Of Reddit's Advice Communities, Emily Cannon, Bianca Crouse, Souvick Ghosh, Nicholas Rihn, Kristen Chua

Faculty Research, Scholarly, and Creative Activity

Advice forums are a crowdsourced way to reinforce cultural norms and moral behavior. Sites like Reddit contain massive amounts of natural language human interaction, with rules and norms unique to each individual subreddit community. To explore this data, we created a dataset with top 1000 posts from each of two such forums, r/AmItheAsshole and r/relationships, and extracted natural language features including sentiment, similarity, word frequency, and demographics using both algorithmic and manual methods. Further, we developed a method to extract demographic information from the subreddits, examined how the post authors' self-disclosures reflect the unique communities in which their posts are …

Economic Analysis Of Sunflower (Helianthus Annuus) Spacing In East Texas, Carly Wright

Electronic Theses and Dissertations

Two experiments were conducted on spacing of Helianthus annuus in East Texas to determine the spacing treatment that produces the greatest revenue per m². The experiments had four spacing treatments of 8 × 15 cm, 15 × 15 cm, 23 × 23 cm, and 30 × 30 cm. Three different cultivars were used in each experiment to determine if there was an interaction between spacing and cultivars. In both experiments, the stem height, stem diameter, flower diameter, and disk diameter increased as spacing increased. Also, as spacing increased, the days-to-harvest decreased. The 8 × 15 cm spacing produced …

Abuse Just Out Of Frame: The Impact Of Online Dispute Resolution On Domestic Violence, Haley Benson

Journal of Dispute Resolution

“This is a[n] issue we didn’t have when we had live court.” It was a chilling day for prosecutor Deborah Davis when she discovered a victim of domestic violence was in the same apartment as her abuser during a session of Zoom court. In this case, the survivor had done the hardest part; she had made the decision to prosecute her abuser. As court began, Davis saw that her client had a similar virtual background to the alleged abuser and noticed that her client was looking away from the camera while answering questions. This prompted Davis to request that police …

Charting A Middle Course For Court-Connected Mediation, John Lande

Journal of Dispute Resolution

Court-connected mediation programs have produced important benefits for parties, practitioners, courts, and society generally. These programs have helped lawyers settle tough cases and generally manage their workload while their clients retain the power to litigate if they cannot reach an acceptable agreement. Courts have created and enforced rules to protect the integrity of process so that parties’ time and money in mediation are well spent.

Restorative Justice: An Alternative Dispute Resolution Approach To Criminal Behavior, Kayla Welch

Journal of Dispute Resolution

Beginning with the end of the Mass Prison Era in the late 1800s, Americans have looked for a better way to respond to crime and those who commit it. Since the Reformatory Era, the United States has swayed between punitive models based on either the Reformatory or Retributive theories. Despite the changes we have made, our criminal justice system suffers from long waiting periods for a trial, overburdened public defenders, overcrowded jails and prisons that often lead to unsafe conditions for the inmates and corrections officers, and many other problems.

Benchmarking Compositionality With Formal Languages, Josef Valvoda, Naomi Saphra, Jonathan Rawski, Adina Williams, Ryan Cotterell

Faculty Research, Scholarly, and Creative Activity

Recombining known primitive concepts into larger novel combinations is a quintessentially human cognitive capability. Whether large neural models in NLP can acquire this ability while learning from data is an open question. In this paper, we investigate this problem from the perspective of formal languages. We use deterministic finite-state transducers to make an unbounded number of datasets with controllable properties governing compositionality. By randomly sampling over many transducers, we explore which of their properties contribute to learnability of a compositional relation by a neural network. We find that the models either learn the relations completely or not at all. The …

Review Of Daniel Farber, Inequality And Regulation: Designing Rules To Address Race, Poverty, And Environmental Law, David A. Weisbach

Coase-Sandor Institute for Law & Economics Research Paper Series

Dan Farber’s wide-ranging article, Inequality and Regulation, makes two core arguments. First, Farber argues that using a uniform value of statistical life (VSL) in cost-benefit analysis is justified not only as a pragmatic compromise but also as a matter of first principles. In particular, he argues that a uniform VSL can be based on a theory of equality that he calls harm egalitarianism, which holds that individuals have equal entitlements to protection against harm. Second, Farber, looking for ways to address environmental justice concerns through regulations, argues that “a heightened focus on differences in exposure and vulnerability [in the cost-benefit …

Antisocial Personality Disorder: A Theoretical Approach Utilizing Three Dimensions Of Power Analysis, Timothy J. Nguyen, Tara Zolnikov

Faculty Research, Scholarly, and Creative Activity

Antisocial Personality Disorder (ASPD) is often associated with high costs and burden to the rest of society; however, it remains a disorder with no evidence of effective traditional psychological interventions. This theoretical study aimed to analyze the phenomenon of power and how it may influence the conceptualization of ASPD. Data was collected through a comprehensive and systematic review of the current ASPD literature. Findings suggested ASPD as severely conceptually flawed, highly imbalanced in terms of power dynamics between professionals and people diagnosed with ASPD, absent of participants’ voices, absent of any effective traditional psychotherapy interventions, disproportionately focused on deficit-oriented strategies …

The Role Of Experts In Policymaking: An Assessment Of Witness Educational Backgrounds In Congressional Testimony, Benedicte Adair

Theses

This thesis provides a first-of-its kind benchmark on the extent to which academically-trained professionals in the United States are availed of opportunities to directly deliver evidence to the United States Congress, as well as how contemporary party politics shapes this system. We randomly sample and manually code the educational backgrounds of 2,147 witnesses from 32 Congressional Committee Hearings that occurred between 2001 and 2020. This study reveals three key findings. The first is that academically-trained professionals have extensive access to the halls of Congress. Second, that all types of degrees have at least some representation amongst witness calls. The third …

Predicting Students' Mental Disorders Using Machine Learning, Maryam Sadiq

Theses

The mental health issues among students are prevailing due to predictions of low mood, anxiety, depression, and academic difficulties. Late diagnosis of these mental health issues takes prolonged measures to minimise its impact. Nowadays, machine learning is used to assess mental health by detecting signals that provide information about mental health through brain scans and questionnaires. Early detection of mental health issues in students possible to control them effectively. Colleges and universities are trying to improve student care by assessing their mental health and reducing mental health problems through psychological therapies. Machine learning techniques, including Multiclass Classifier, LAD Tree, and …

Getting Proactive With Police Proactivity: The Benefits Of Computer-Aided Dispatch For Directing Police Resources To Areas Of Need, Kris Henning, Christian Peterson, Greg Stewart, Kimberly Kahn, Yves Labissiere, Brian Renauer, Renee Mitchell, Sean Sothern

Criminology and Criminal Justice Faculty Publications and Presentations

Sherman and colleagues (2014) argue that crime reductions associated with hot spot policing can be maximized by carefully managing the dosage of supplemental resources delivered. Fully achieving this goal in prior studies has been difficult due to resistance by officers, the use of atypical strategies for directing patrols to target locations, and insufficient attention to the measurement of treatment dosages. This has led to calls for process research examining the implementation of hot spot policing in law enforcement agencies. The current study represents one such effort. The computer-aided dispatch (CAD) system for a large U.S. police department was pre-programmed with …

Controlling Fairness In Standard Form Contracts: What Can Courts Do, And What Should They Do?, Marcus Moore

All Faculty Publications

Unfair terms in standard form contracts are one of Contract Law's most notorious and enduring problems. The vast transnational literature on this, now a century old, has long worked out its contours, even as it still searches for more effective solutions. The central problem can be simply stated: A form drafter's ability to dictate terms-characteristically unknown and unbargained by the parties who are form recipients-allows, in the absence of any other legal control, for the incorporation of one-sided terms favouring the drafting party. The implications are significant: The exhaustive list of terms typical of such contracts, combined with the pervasiveness …

Competition And Congestion In Trademark Law, Christopher Buccafusco, Jonathan S. Masur, Mark P. Mckenna

Coase-Sandor Institute for Law & Economics Research Paper Series

Trademark law exists to promote competition. If consumers know which companies make which products, they can more easily find the products they actually want to purchase. Trademark law has long treated “source significance”—the fact that a particular trademark is identified with a particular producer—as both necessary and sufficient for establishing a valid trademark. That is, trademark law has traditionally viewed source significance as the only necessary precondition for a trademark being pro-competitive. In this paper, we argue that this equation of source significance and pro-competitiveness is misguided. Some marks use words that are so closely connected with the product being …
