In Their Words: Prospective Teachers' Experiences As A Context For Investigating Their Views Of Authority In A Mathematics Classroom, Brenda Lynn Rosencrans

Dissertations and Theses

Mathematics teacher educators enact inquiry-based preparatory courses with the underlying expectation that their students (prospective teachers) will take ownership (authority) of their mathematical learning through sharing their ideas and collaboratively discussing the reasonableness of their shared ideas. Yet, prospective teachers' expectations are often not yet in alignment with those of mathematics teacher educators, instead they enter these courses expecting their instructors to provide clear examples and directions for how to solve mathematics problems. This project investigates this dynamic through an authority lens, seeking to understand and characterize different views of authority prospective teachers hold and the impact these views have …

Integrating Behavioral Research Findings With A Liberal Arts Paradigm, Jonathan Peterson

LSU Master's Theses

This paper explores the role of behavioral research in understanding the complexity and relevance of creativity. A brief history of the liberal arts and its current application is followed by a discussion of the importance of variability in generating novel and diverse responses, challenging the notion that creativity is solely a product of innate talent. The effects of reinforcement on variability, and how it relates to a complex relationship between reinforcement and the probability of variable responding leads to a discussion of how the combination of previously trained behaviors can lead to creative problem-solving, emphasizing the role of combinatory behavior …

Machine Learning Approach For Static Ransomware Analysis, Aldin Vehabovic

USF Tampa Graduate Theses and Dissertations

Ransomware is a form of malware which uses encryption methods to make data inaccessible to legitimate users. This cyberthreat has emerged as one of the most serious security challenges today, and a wide range of ransomware families have been developed and deployed, causing immense damage to governments, corporations, and private users. As this malware type continues to expand, governments across the world are taking serious steps to limit its reach. In addition, researchers have proposed a range of ransomware detection and attribution schemes, most of which use advanced machine learning (ML) techniques to process and analyze real-world empirical data from …

The Characteristics Of Successful Military It Projects: A Cross-Country Empirical Study, Helene Berg, Jonathan D. Ritschel

Faculty Publications

In the armed forces, successful digitalization is crucial to ensure effective operations. Much of the existing literature on project factors during the planning and execution phases of public IT projects do not focus specifically on military sector projects. Therefore, the paper aims to provide empirical insights into the characteristics of successful military IT projects. Data from such projects in NATO countries and agencies were collected through interviews and project documents. The findings relating to the main variable of interest, “delivery of client benefit,” supported previous findings on IT project performance. Medium-sized projects performed better than small and large projects, and …

Exploration Of Efficient Dewatering Methods In Stimulus-Responsive Hydrogels And Their Potential For Desalination, Weiliang Sun

LSU Doctoral Dissertations

Addressing global freshwater scarcity is a pressing challenge, and desalination has emerged as a viable solution to generate high-quality water without compromising natural freshwater ecosystems. In comparison to conventional desalination methods such as thermal distillation and membrane-based processes, hydrogels offer distinct advantages including strong water absorption, water retention, well-defined pore structures, customizable functional groups, and responsive properties to external stimuli. These unique characteristics position hydrogels as promising candidates for water treatment applications. Hydrogel-based desalination involves the utilization of hydrogels to absorb water from saltwater, and then discharge low-concentration solutions to obtain reclaimed water. The fundamental principle underlying the desalination ability …

Abstract

Electrochemical CO₂ reduction (ECO₂RR) has emerged as a promising approach for generating carbon-neutral liquid fuels by utilizing excess renewable electricity to convert CO₂. This thesis aims to employ atomistic simulations by using Density Functional Theory (DFT) to investigate the mechanistic details of how transition metal sulfides and electro-organocatalysts can enhance the activity and selectivity towards desired products, including those containing C-H bonds and molecules with C-C bonds. For this project, three different electrocatalysts were designed computationally.

Firstly, MoS₂ was chosen as a transition metal sulfide catalyst with the objective of understanding the kinetics …

Predicted Structure And Functional Roles Of Alphaherpesvirus Tegument Protein Ul37 In Virion Morphogenesis And Innate Immunity, Therese Marie Collantes

LSU Doctoral Dissertations

Several members of the Family Herpesviridae are clinically significant pathogens, affecting humans and a wide range of animals. Alphaherpesviruses infect epithelial cells at the primary site of infection and subsequently invade adjacent sensory neurons. Infectious bovine rhinotracheitis (IBR) is an economically important disease caused by bovine herpesvirus 1 (BoHV-1), which belongs to the subfamily Alphaherpesvirinae, genus Varicellovirus. To date, vaccination is the only preventive measure against IBR. Understanding determinants of herpesvirus replication and innate immune regulation is important to help further develop vaccines that are efficacious and incapable of establishing latency in the host nervous system. The alphaherpesvirus …

Proteoglycan 4 (Prg4)/Lubricin And The Extracellular Matrix In Gout, Khaled A. Elsaid, Gregory D. Jay, Ru Liu-Bryan, Robert Terkeltaub

Pharmacy Faculty Articles and Research

Proteoglycan 4 (PRG4) is a mucinous glycoprotein secreted by synovial fibroblasts and superficial zone chondrocytes, released into synovial fluid, and adsorbed on cartilage and synovial surfaces. PRG4′s roles include cartilage boundary lubrication, synovial homeostasis, immunomodulation, and suppression of inflammation. Gouty arthritis is mediated by monosodium urate (MSU) crystal phagocytosis by synovial macrophages, with NLRP3 inflammasome activation and IL-1β release. The phagocytic receptor CD44 mediates MSU crystal uptake by macrophages. By binding CD44, PRG4 limits MSU crystal uptake and downstream inflammation. PRG4/CD44 signaling is transduced by protein phosphatase 2A, which inhibits NF-κB, decreases xanthine oxidoreductase (XOR), urate production, and ROS-mediated IL-1β …

Tissue Resident Regulatory T Cells And Immunopathology During Influenza Infections, Michael Mcgee

LSU Doctoral Dissertations

Influenza (flu) virus infections are a leading cause of respiratory illness. Globally there are approximately 290,000-650,000 deaths and 3-5 million cases of severe illness during the average flu season. Severe flu infection is associated with the combination of a strong pro-inflammatory and weak anti-inflammatory response. Regulatory T cell subsets suppress pro-inflammatory responses during flu infection, with production of the immunomodulatory cytokine IL-10 playing a critical role in this process. Tissue resident regulatory T cell subsets are maintained within nonlymphoid tissues and are optimally positioned to suppress localized pro-inflammatory responses. However, knowledge of the signaling pathways regulating the development of tissue …

Noise Analysis Of The Indian Pulsar Timing Array Data Release I, Aman Srivastava, Shantanu Desai, Neel Kolhe, Mayuresh Surnis, Bhal Chandra Joshi, Abhimanyu Susobhanan, Aurélien Chalumeau, Shinnosuke Hisano, Nobleson K, Raghav Girgaonkar

Physics & Astronomy Faculty Publications

The Indian Pulsar Timing Array (InPTA) collaboration has recently made its first official data release (DR1) for a sample of 14 pulsars using 3.5 years of uGMRT observations. We present the results of single-pulsar noise analysis for each of these 14 pulsars using the InPTA DR1. For this purpose, we consider white noise, achromatic red noise, dispersion measure (DM) variations, and scattering variations in our analysis. We apply Bayesian model selection to obtain the preferred noise models among these for each pulsar. For PSR J1600−3053, we find no evidence of DM and scattering variations, while for PSR J1909−3744, we find …

Temperature-Pressure Phase Diagram Of Confined Monolayer Water/Ice At First-Principles Accuracy With A Machine-Learning Force Field, Bo Lin, Jian Jiang, Xiao Cheng Zeng, Lei Li

Department of Chemistry: Faculty Publications

Understanding the phase behaviour of nanoconfined water films is of fundamental importance in broad fields of science and engineering. However, the phase behaviour of the thinnest water film – monolayer water – is still incompletely known. Here, we developed a machine-learning force field (MLFF) at first-principles accuracy to determine the phase diagram of monolayer water/ice in nanoconfinement with hydrophobic walls. We observed the spontaneous formation of two previously unreported high-density ices, namely, zigzag quasi-bilayer ice (ZZ-qBI) and branched-zigzag quasi-bilayer ice (bZZ-qBI). Unlike conventional bilayer ices, few inter-layer hydrogen bonds were observed in both quasi-bilayer ices. Notably, the bZZ-qBI entails a …

All That Is Cyber Melts Into Control: A Rhetorical Analysis Of Cybernetic Metaphors, Cem İsmail Addemir

Theses and Dissertations

This thesis historicizes and interprets the logic of cybernetics as a communication technology and how it shaped notions of control in the mid-20th century. To situate my analysis, I focus on cybernetics, the tradition within communication studies that focuses on controlling communication through the application of feedback loops to a particular system. Since the discovery and popularization of cybernetics by the late 1950s, its central logic has been widely applied to computational technology and influenced future systems theories. Specifically, my thesis employs a rhetorical examination of cybernetic metaphors through metaphor criticism to trace the genealogy of cybernetic discourses that I …

Transitioning Statistical Iterative Dual-Energy Ct Reconstruction To The Clinic: Artifact Reduction And Machine Learning-Based Acceleration, Tao Ge

McKelvey School of Engineering Graduate Student Theses & Dissertations

Over the past few decades, dual-energy X-ray computed tomography (DECT) imaging has undergone significant advancements, mainly attributed to its remarkable ability to differentiate between different materials. In contrast to conventional X-ray computed tomography (CT), DECT employs two measurements acquired at distinct spectra, enabling the generation of highly informative and precise images, including material decomposition maps, virtual non-contrast images, and stopping-power maps for proton treatment plans. Image-domain decomposition (IDD) is a widely utilized technique in DECT imaging, assuming that low- and high-energy images can be represented as linear combinations of material decomposition maps on an element-wise basis. On the other hand, …

Ecg Recordings As Predictors Of Very Early Autism Likelihood: A Machine Learning Approach, Deepa Tilwani, Jessica Bradshaw, Amit Sheth, Christian O'Reilly

Publications

In recent years, there has been a rise in the prevalence of autism spectrum disorder (ASD). The diagnosis of ASD requires behavioral observation and standardized testing completed by highly trained experts. Early intervention for ASD can begin as early as 1–2 years of age, but ASD diagnoses are not typically made until ages 2–5 years, thus delaying the start of intervention. There is an urgent need for non-invasive biomarkers to detect ASD in infancy. While previous research using physiological recordings has focused on brain-based biomarkers of ASD, this study investigated the potential of electrocardiogram (ECG) recordings as an ASD biomarker …

Multiple Ways To Implement And Infer Sentience, Nicolas Rouleau, Michael Levin

Animal Sentience

Segundo-Ortin & Calvo’s (S&C’s) thorough review of “plant neurobiology” presents evidence supporting the possibility of plant sentience. They make a compelling case that plants anticipate, assess risk, cooperate, mimic, and pursue goals, as do their animal counterparts. S&C point out that there is a double standard: behavioural patterns associated with subjective experiences in humans are considered valid for inferring cognition in non-human animals but not in diverse other systems including plants. We argue that cognitive functions, including sentience, can potentially be achieved by very different systems and their disparate substrates. We offer some context from the basal cognition literature and …

Measurements Of Scintillation Light Quenching For Protons In Rare-Earth Inorganic Scintillators, Tatiana Nathaly Espinoza

Nuclear Engineering ETDs

Scintillator detectors have become a leading choice of radiation detectors for a variety of applications, including space science. Due to their intrinsic characteristics, rare-earth inorganic scintillators provide the capability to detect both gamma and charged particles in a small detector. The response of these detectors is typically characterized using isotropic gamma sources. However, the light output produced in the scintillator from an incident gamma of a particular energy differs from the light output produced from an incident charged particle of the same energy; a phenomenon known as quenching. Using two types of rare-earth inorganic scintillators, Y2SiO5(YSO:Ce), and Gd₃Al₂Ga₃O₁₂(GAGG:Ce), we measured …

Emt Activates Exocytotic Rabs To Coordinate Invasion And Immunosuppression In Lung Cancer, Guan-Yu Xiao, Xiaochao Tan, Bertha L Rodriguez, Don L Gibbons, Shike Wang, Xin Liu, Mayra E Vasquez, Hai T Tran, Jun Xu, William K Russell, Cara Haymaker, Younghee Lee, Jianjun Zhang, Luisa Solis, Ignacio I Wistuba, Jonathan M Kurie

Faculty, Staff and Student Publications

Epithelial-to-mesenchymal transition (EMT) underlies immunosuppression, drug resistance, and metastasis in epithelial malignancies. However, the way in which EMT orchestrates disparate biological processes remains unclear. Here, we identify an EMT-activated vesicular trafficking network that coordinates promigratory focal adhesion dynamics with an immunosuppressive secretory program in lung adenocarcinoma (LUAD). The EMT-activating transcription factor ZEB1 drives exocytotic vesicular trafficking by relieving Rab6A, Rab8A, and guanine nucleotide exchange factors from miR-148a-dependent silencing, thereby facilitating MMP14-dependent focal adhesion turnover in LUAD cells and autotaxin-mediated CD8

High Throughput Single Cell Long-Read Sequencing Analyses Of Same-Cell Genotypes And Phenotypes In Human Tumors, Cheng-Kai Shiau, Lina Lu, Rachel Kieser, Kazutaka Fukumura, Timothy Pan, Jie Yang, Gahyun Lee, Yuanqing Yan, Jason T Huse, Ruli Gao

Faculty, Staff and Student Publications

Single-cell nanopore sequencing of full-length mRNAs transforms single-cell multi-omics studies. However, challenges include high sequencing errors and dependence on short-reads and/or barcode whitelists. To address these, we develop scNanoGPS to calculate same-cell genotypes (mutations) and phenotypes (gene/isoform expressions) without short-read nor whitelist guidance. We apply scNanoGPS onto 23,587 long-read transcriptomes from 4 tumors and 2 cell-lines. Standalone, scNanoGPS deconvolutes error-prone long-reads into single-cells and single-molecules, and simultaneously accesses both phenotypes and genotypes of individual cells. Our analyses reveal that tumor and stroma/immune cells express distinct combination of isoforms (DCIs). In a kidney tumor, we identify 924 DCI genes involved in …

Controls On The Stratiform Copper Mineralization In The Western Syncline, Upper Peninsula, Michigan, William C. Williams, Theodore J. Bornhorst

Michigan Tech Publications

The Western Syncline hosts reduced-facies, or Kupferschiefer-type, sedimentary rock-hosted stratiform Cu deposits (SSC) in the lowermost meters of the Nonesuch Formation, which is part of a thick section of clastic sedimentary rocks that comprise the upper fill of the Mesoproterozoic Midcontinent Rift of North America. Located in the Porcupine Mountains Cu district in Upper Peninsula, Michigan, these blind deposits were discovered in 1956, but are not yet developed, although recent renewed interest may result in near-term production. The deposits are distinguished by their relatively undeformed nature and lack of superposed hydrothermal events. Prior to lithification, chalcocite mineralization replaced diagenetic pyrite …

An Application Of Theil Indexes For The Interrater Reliability: A Comparison With Intraclass Correlations, Tianshu Pan, Yue Yin

Chinese/English Journal of Educational Measurement and Evaluation | 教育测量与评估双语期刊

This study proposes to apply the Theil-index ratios for the interrater reliability. We discuss the theoretical foundations and examine its function empirically using real data. Our analyses show that Theil-index rations and intraclass correlation (ICC) estimates are highly correlated. However, ICC may underestimate the interrater reliability by some extreme disagreement among raters and be more likely to be influenced by the extreme disagreement. As Theil-index ratios overcome the limitations of ICC to some degree, it seems that Theil-index ratios provide an alternative to evaluating interrater reliability, at least under certain conditions, e.g., when outliers exist in the data, it is …
