Causal Attribution Tendencies Of Early Childhood Practitioners And The Efficacy Of Attribution Retraining, Alex J. Faucheux

UNLV Theses, Dissertations, Professional Papers, and Capstones

Early childhood practitioners frequently attempt to identify the cause of outcomes experienced by their learners. This is sometimes referred to as causal attribution. Causal attribution may be affected by prior success and failure of a learner, the amount of effort exerted by the learner, the ability level of the learner, and knowledge of any disability associated with the learner, all of which can be considered controllable or uncontrollable, stable or unstable, and internal or external (Weiner, 1986; Woodcock & Vialle, 2011). As practitioners attribute cause to outcomes, they start to develop attributional tendencies; these tendencies, along with the cues and …

Roadblocks To Momentum: An Analysis Of College Major Gpa Restrictions And Stranded Students, Michael J. Hack

UNLV Theses, Dissertations, Professional Papers, and Capstones

College retention, persistence, and completion are key indicators of a successful institution, but six-year degree completion has remained stagnant in recent years (National Student Clearinghouse Research Center, 2022). Despite institutional efforts through success initiatives to keep students retained, one set of barriers to degree completion may be due to established major GPA restrictions and policies that prevent students from being able to declare their majors. Accordingly, students who are unable to declare their major but keep enrolling in courses may be in danger of becoming “stranded.” This quantitative examination of student data from one large public four-year college aims to …

Various factors, including monoethanolamine (MEA) concentrations of 1, 10, and 30 wt.%; water-to-cement ratios (w/cm) of 0.35, 0.4, and 0.5; coating timings on day 3 and day 27; and pre-conditioning methods such as air drying, are investigated for their impact on the performance of chloride penetration resistance. Specifically, pre-conditioning significantly enhanced …

Modeling Inflation Transmission Among Different Construction Materials, Mohamad Abdul Nabi, Islam H. El-Adaway, Rayan H. Assaad

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Cost estimating in the construction industry is challenging due to the high uncertainty associated with the supply chain, especially after the COVID-19 pandemic. Some research studies have addressed such problems by developing models that predict material cost. In fact, all material can be interconnected and interrelated with lead-lag relationships such that any inflation in one material's price can be associated with inflation in other materials' prices, referred to as transmission of inflation. Despite the latter, none of the existing studies have investigated inflation transmission among all construction materials. This paper fills this knowledge gap. The authors used a multistep research …

A Review Of Whipple Shield Ballistic Limit Equations, S. Ryan, W. (William) P. Schonberg

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Ballistic limit equations (BLEs) are semi-analytical expressions used to predict the risk posed by micrometeoroid and orbital debris (MMOD) impacts on a spacecraft. A foundational BLE, known as the new non-optimum (NNO) equation was published by Eric Christiansen of NASA Johnson Space Center in 1990 for application on Whipple shields – two-plate configurations consisting of a thin sacrificial plate located at some standoff in front of the spacecraft pressure hull or structural wall. Today, BLEs for almost all multi-plate spacecraft structures, e.g., honeycomb sandwich panels, monolithic structures with thermal insulation blankets, etc., are based on the NNO Whipple BLE. We …

The Influence Of Personal Factors On Wrongful Convictions, Ellee Jackson

Masters Theses and Doctoral Dissertations

Previous work has identified factors that influence the likelihood of wrongful conviction. However, fewer efforts have been made to examine how these factors influence the amount of time between wrongful conviction and exoneration. This is crucial to the expansion of innocence research and the contextualization of wrongful convictions within the criminal justice system. This study employs negative binomial regression to analyze data collected by the National Registry of Exonerations (NRE). Using a sample of 2,349 cases in which the most severe conviction was murder, sexual assault, child sexual abuse, or drug possession, I examine the influence of an exoneree’s age, …

Persistent Identifiers And The Next Generation Of Legal Scholarship, Aaron Retteen, Malikah Hall-Retteen

Faculty Scholarship

This article discusses the importance of the most common persistent identifiers in scholarly communications—the digital object identifier and the ORCID identifier—to legal scholarship. Persistent identifiers help preserve and disseminate academic content and data-driven services that leverage this information standard are now integrated into the publication process. Because legal publishers have not widely adopted persistent identifiers, the legal discipline cannot enjoy the benefits offered by this system. This article looks at barriers to implementing persistent identifiers among legal publishers and provides an anecdotal example of creating a sustainable workflow between the law library and student-run law journals.

"Into The Womb Of Solipsism": The Spectrum Of Loneliness In Wallace's Infinite Jest, Michael Gieger

Theses, Dissertations and Culminating Projects

Academic critics and casual readers of David Foster Wallace’s 1,079-page novel, Infinite Jest, have long ruminated over the book’s daunting physical size and wide narrative scope. This paper offers an argumentative interpretation of the novel’s immensity through an exploration of Wallace’s thematic preoccupation with solipsism and human loneliness. Building primarily from the critical works of Frank Cioffi and Casey Michael Henry, this essay makes the contention that the length of Infinite Jest behaves mimetically, simulating for its attentive readership a sense of perpetual emotional isolation—an isolation reflective of the epic’s untold lonesome characters. The argument further suggests that length of …

Explaining Misinformation Detection Using Large Language Models, Vishnu S. Pendyala, Christopher E. Hall

Faculty Research, Scholarly, and Creative Activity

Large language models (LLMs) are a compressed repository of a vast corpus of valuable information on which they are trained. Therefore, this work hypothesizes that LLMs such as Llama, Orca, Falcon, and Mistral can be used for misinformation detection by making them cross-check new information with the repository on which they are trained. Accordingly, this paper describes the findings from the investigation of the abilities of LLMs in detecting misinformation on multiple datasets. The results are interpreted using explainable AI techniques such as Local Interpretable Model-Agnostic Explanations (LIME), SHapley Additive exPlanations (SHAP), and Integrated Gradients. The LLMs themselves are also …

Development And Evaluation Of A Modeling Platform For Evaluating Immunotherapeutic Efficacy In The Tumor Microenvironment., Dylan Andrew Goodin

Electronic Theses and Dissertations

The tumor microenvironment (TME) represents the complex outcome of numerous tumor, stromal, and immune interactions, and whose composition can significantly affect treatment response. Particularly, immunotherapeutic efficacy is subject to multiple tumor-specific TME interactions that may be difficult to evaluate/predict clinically. Mathematical modelling has been formulated to evaluate specific aspects of the TME, including vasculature, ECM deposition, and immune-tumor interactions. However, the computational challenge of simulating multiple TME interactions has led to sacrificing varying degrees of model generalizability and clinical relevance. This work describes increased computational performance of a 3D continuum model that simulates tumor tissue, ECM, and vasculature using a …

Authentic Fake: Authenticity And Authentication., Suyun Son

Electronic Theses and Dissertations

My thesis exhibition questions the modern sanctification of authenticity. No longer believing in objective truths, the postmodern society seeks epistemic grounding on being true to oneself. The categories of authentic-or-fake replaced the binary of true-or-false. But authenticity is a trojan horse for authentication. As a Korean American artist, I'm encouraged to express my “authentic” Korean identity. This encouragement can also imply my works will receive recognition as authentic and meaningful only when they embody Korean cultural expression. Authenticity becomes a performance for the sake of authentication. Ironically, authenticity turns into an act of conformity/confirmation. Authenticity demands you stay true to …

Faculty And "Teams": Academic Literacies In The Post-Lockdown, Digital University., Morgan Suzanne Blair

Electronic Theses and Dissertations

The increased presence of disruptive digital technologies in academia has been a subject of multidisciplinary scholarly conversation and public speculation over the past few decades. Many literacy studies scholars have contributed to this discourse, examining topics like multimodal literacies and perceptions of agency among students. These scholars have noted with skepticism that such technologies may mask operations of power, surveillance, and control which serve the demands of an increasingly “corporate” or “neoliberal” university. Building upon this scholarship, my study contends that the evolving literacy environment of the digital university requires a closer examination of corporate-sponsored narratives and literacy practices implicating …

Spinal cord injury (SCI) affects the central nervous system (CNS) causing muscle paralysis and autonomic dysfunctions throughout the body. Muscle activation after SCI is essential to facilitate functional recovery and may be produced via remaining input from supraspinal centers, the central pattern generators (CPG), or muscle stretch reflex responses. In this study, assisted leg cycling is evaluated as a tool to identify the neural structure control of muscle activation after motor complete SCI. Eight individuals with a complete or sensory incomplete SCI between C2 and T5 participated in the study. Participants completed leg cycling trials with and without supraspinal intention …

Origin Stories., Danielle Deeley

Electronic Theses and Dissertations

This thesis is an investigation into the Peruvian pre-Columbian collection at the Speed Art Museum in Louisville, Kentucky. The Speed Art Museum acquired this collection in 1934 and it has largely remained unresearched for nearly a century after acquisition into the museum’s collection. This investigation is not an attempt to make broad characterizations of pre-Columbian ceramics. Nor is its goal to fill in all the gaps of the collection’s history. Instead, this thesis follows the evidence the collection presents: the physical attributes of the ceramics, the donor’s history, U.S. history, and information from the collection file provided by the Speed …
