Perceptions Of Secondary School Mathematics Teachers Regarding Teaching Mathematics With Conceptual Understanding, Latisa Williams

Theses and Dissertations

This dissertation was designed to provide current knowledge on the mindset of secondary school mathematics teachers regarding the use of Conceptual Understanding (CU) as an approach to teaching the subject. It is well-documented that when students learn to engage in mathematical conceptual explanations in meaningful ways, they improve their learning. However, reports have shown that students in secondary schools lack effective skills in explaining and applying CU for successful problem-solving. As a result, teachers struggle with methods of instruction that can effectively improve the level of CU with their students in mathematics.

For this study, the researcher used a qualitative …

The Tragic Costs Of ‘Protecting’ Trans Youth, Kimberly Jade Norwood, Jaimie Hileman

Scholarship@WashULaw

In the past few decades, our nation has made substantial progress on the rights of LGBTQ+ people. The legalization of gay marriage in Obergefell v. Hodges in 2015 was transformative for our nation. Just five years later, another huge victory was scored in Bostock v. Clayton County, Georgia, when the U.S. Supreme Court ruled that Title VII of the Civil Rights Act of 1964 protected gay and transgender people.

With every gain, backlash often follows. Three years after Bostock, a tsunami of anti-LGBTQ+ bills, and more specifically, anti-Trans bills, littered the nation. Hundreds of bills have been filed since Bostock, …

Redistributing Justice, Benjamin Levin, Kate Levine

Scholarship@WashULaw

This article surfaces an obstacle to decarceration hiding in plain sight: progressives’ continued support for the carceral system. Despite increasingly prevalent critiques of criminal law from progressives, there hardly is a consensus on the left in opposition to the carceral state. Many left-leaning academics and activists who may critique the criminal system writ large remain enthusiastic about criminal law in certain areas—often areas where defendants are imagined as powerful and victims as particularly vulnerable. In this article, we offer a novel theory for what animates the seemingly conflicted attitude among progressives toward criminal punishment—the hope that the criminal system can …

Engineering Mussel Foot Protein 5 (Mfp5) For Enhanced Adhesive Performance In Tendon And Bone Repair, Ziyue Zhu

McKelvey School of Engineering Graduate Student Theses & Dissertations

This study explores the development of Mussel Foot Protein 5 (MFP5) bioadhesives to improve tendon-to-tendon and tendon-to-bone adhesive outcomes. MFP5, known for its underwater adhesive properties, was synthesized using recombinant techniques and optimized through coacervation and cross-linking. Adhesion tests demonstrated the superior performance of the optimized MFP5 adhesive on the tendon and bone samples. Improved protein concentration testing and purification methods enhanced MFP5 yield and consistency. Future research will focus on further standardization, exploring alternative purification methods, and evaluating the adhesive's performance in animal models. This study lays a foundation for developing robust MFP5-based bioadhesives, potentially revolutionizing surgical repair techniques …

Late-Arriving Votes And Electoral Fraud: A Natural Experiment And Regression Discontinuity Evidence From Bolivia, Diego Escobari, Gary A. Hoover

School of Economics and Finance Faculty Publications

This paper uses a unique data set and a natural experiment to test if electoral fraud can exist in late-arriving votes. On the night of the 2019 Bolivian elections, the official vote counting system that was expected to publish the results real-time, suddenly stopped. When it resumed, the results had flipped. We estimate several difference-in-differences specifications using a 2016 referendum and the votes of other political parties. We find that the extent of the fraud is 2.51% of the valid votes, sufficient to change the outcome of the election. Our results are robust to polling-station-level shocks common across 2019 and …

Economic Growth Before And After The Fiscal Stimulus Of 2008–2009: The Role Of Institutional Quality And Government Size, André Varella Mollick, Andre Coelho Vianna

School of Economics and Finance Faculty Publications

Governments implemented fiscal stimulus packages to alleviate the global financial crisis of 2007–2009. Using annual data from 1996 to 2019, we investigate economic growth in a large sample of countries for pre-and post-Global Financial Crisis years. Our approach analyzes the interaction between institutional quality and government size (government expenditures as share of GDP), reinforced by threshold estimations. We document that economies react to government size depending on the quality of the institutions in question. First, fixed effects models indicate higher institutional quality has positive effects on growth, while government size—and its interactions with institutional quality—has negative effects. Second, the coefficients …

Identifying Missing Is-A Relations In Snomed Ct With Fine-Tuned Pre-Trained Language Models And Non-Lattice Subgraphs, Xubing Hao, Rashmie Abeysinghe, Jay Shi, Guo-Qiang Zhang, Licong Cui

Faculty, Staff and Student Publications

Ensuring the completeness of IS-A relations in SNOMED CT is crucial for maintaining its accuracy in clinical applications. In this study, we propose a hybrid approach leveraging non-lattice subgraphs and pre-trained language models (PLMs) to identify missing IS-A relations in SNOMED CT. We fine-tuned four BERT-based models: BERT, DistillBERT, DeBERTa, and BioClinicalBERT, and four generative large language models (LLMs): BioMistral, Llama3, Gemma2, and Phi-4. Missing IS-A relations were identified through consensus predictions by all eight models. De-BERTa achieved the best performance (precision: 0.96, recall: 0.97, F1-score: 0.965) for IS-A relation prediction. Our approach identified 678 potential missing IS-A relations in …

Diagnostic Value Of Soluble Interleukin-2 Receptor In Patients Suffering Neurosarcoidosis: A Systematic Review, Aditya Chanpura, Rajesh K Gupta, Shitiz K Sriwastava, Jan Rahmig

Faculty, Staff and Student Publications

Background: Neurosarcoidosis is an inflammatory granulomatous disease. Up to 25% of occult sarcoidosis affecting the nervous system are only detected by autopsy. In addition, in recent years the suspicion arose that the soluble Interleukin-2 Receptor (sIL-2R) might be useful in differentiating between neurosarcoidosis and neurosarcoidosis-like diseases such as neurotuberculosis, multiple sclerosis, or cerebral lymphoma.

Objectives: Therefore, we aimed to systematically review randomized controlled trials (RCT), observational studies, and case-control studies evaluating sIL-2R levels in neurosarcoidosis patients.

Design: For this systematic review, a comprehensive literature search of electronic databases including EMBASE, The Web Of Science, The Cochrane Library, MEDLINE, and Google …

Is It All Hype? Chatgpt’S Performance And Disruptive Potential In The Accounting And Auditing Industries, Marc Eulerich, Aida Sanatizadeh, Hamid Vakilzadeh, David A. Wood

Faculty Publications

ChatGPT frequently appears in the media, with many predicting significant disruptions, especially in the fields of accounting and auditing. Yet research has demonstrated relatively poor performance of ChatGPT on student assessment questions. We extend this research to examine whether more recent ChatGPT models and capabilities can pass major accounting certification exams including the Certified Public Accountant (CPA), Certified Management Accountant (CMA), Certified Internal Auditor (CIA), and Enrolled Agent (EA) certification exams. We find that the ChatGPT 3.5 model cannot pass any exam (average score across all assessments of 53.1%). However, with additional enhancements, ChatGPT can pass all sections of each …

Anomaly Time, Boone Bowles, Adam V. Reed, Matthew C. Ringgenberg, Jacob Thornock

Faculty Publications

We examine the timing of returns around the publication of anomaly trading signals. Using a database that captures when information is first publicly released, we show that anomaly returns are concentrated in the first month after information release dates, and these returns decay soon thereafter. We also show that the academic convention of forming portfolios in June underestimates predictability because it uses stale information, which makes some anomalies appear insignificant. In contrast, we show many anomalies do predict returns if portfolios are formed immediately after information releases. Finally, we develop guidance on forming portfolios without using stale information.

Background: The use of low titer group O whole blood (LTOWB) for resuscitation of patients with traumatic hemorrhage is becoming increasingly common. Practices regarding the administration of RhD-positive LTOWB to childbearing age females (CBAFs) vary between institutions due to concerns about RhD alloimmunization. This study examined practices related to LTOWB transfusion as they pertain to age and sex.

Methods: This was a secondary analysis of the Shock, Whole blood, and Assessment of TBI (traumatic brain injury) trial, a prospective, multicenter observational cohort study where outcomes following LTOWB transfusion were analyzed at seven level 1 trauma centers between 2018 and 2021, …

Radiation Force Modeling For A Wave Energy Converter Array, Salman Husain, Gordon Parker, David Forehand, Enrico Anderlini

Michigan Tech Publications

The motivation and focus of this work is to generate passive transfer function matrices that model the radiation forces for an array of WECs. Multivariable control design is often based on linear time-invariant (LTI) systems such as state-space or transfer function matrix models. The intended use is for designing real-time control strategies where knowledge of the model’s poles and zeros is helpful. This work presents a passivity-based approach to estimate radiation force transfer functions that accurately replace the convolution operation in the Cummins equation while preserving the physical properties of the radiation function. A two-stage numerical optimization approach is used, …

Prophylactic Mesh Reinforcement For Non-Midline Incisions: A Systematic Review, Rainna Coelho, Oluwatunmininu Anwoju, Ali Siddiqui, Andrew Youssef, Oscar A Olavarria, Naila H Dhanani, Karla Bernardi, Zuhair Ali, Mike K Liang

Faculty, Staff and Student Publications

Background: Many abdominal-pelvic surgeries utilize incisions not along the linea alba, such as transverse, laparoscopic, ostomy reversal, or ostomy formation incisions. The prevalence of ventral incisional hernias (VIH) at these sites and the efficacy of prophylactic mesh in preventing VIH remains unclear.

Methods: PubMed, Embase, Scopus, and Cochrane databases were systematically reviewed from inception to September 2022. We included published randomized controlled trials (RCTs) that compared prophylactic mesh reinforcement versus no mesh. The primary outcome was the incidence of VIH at postoperative follow-up equal to or greater than 24 months. Secondary outcomes included surgical site infection (SSI) and surgical site …

One-Step Production Of Fully Biotinylated And Glycosylated Human Fc Gamma Receptors, Minhyo Kang, Zening Wang, Xin Ge

Faculty, Staff and Student Publications

Initiating and regulating humoral immunity, Fc gamma receptors (FcγRs) have been identified both as therapeutics and as drug targets, and thus production of biologically active FcγRs is highly demanded for biopharmaceutical development. Focusing on low-affinity FcγRs IIA (131H/R allotypes), IIB, and IIIA (176F/V), this study used human 293-F cells to achieve correct post-translational modifications (PTMs) including biotinylation, N-glycosylation, and disulfides. Approaches involving co-expression of FcγR-AviTag and Escherichia coli biotin ligase BirA, endoplasmic reticulum retention, stable and transient transfections, and optimization of transgene ratio were investigated. Protein electrophoresis under reducing and non-reducing conditions, enzymatic deglycosylation, streptavidin pull-down assays, and binding kinetic …

Proportional Sway-Based Electrotactile Feedback Improves Lateral Standing Balance, V S Raghav Hari Krishna, Jeonghee Kim, Shuo-Hsiu Chang, Yoonsuck Choe, Hangue Park

Faculty, Staff and Student Publications

INTRODUCTION: Plantar cutaneous augmentation is a promising approach in balance rehabilitation by enhancing motion-dependent sensory feedback. The effect of plantar cutaneous augmentation on balance has been mainly investigated in its passive form (e.g., textured insole) or on lower-limb amputees. In this study, we tested the effect of plantar cutaneous augmentation on balance in its active form (i.e., electrical stimulation) for individuals with intact limbs.

METHODS: Ten healthy subjects participated in the study and were instructed to maintain their balance as long as possible on the balance board, with or without electrotactile feedback evoked on the medial side of the heel, …

Precision Needle-Punch Tumor Enrichment From Paraffin Blocks Improves The Detection Of Clinically Actionable Genomic Alterations And Biomarkers, Douglas I Lin, Richard S P Huang, Ioannis Ladas, Rachel B Keller, Nimesh R Patel, Sotirios Lakis, Brennan Decker, Tyler Janovitz, Douglas A Mata, Jeffrey S Ross, Jo-Anne Vergilio, Julia A Elvin, Roy S Herbst, Philip C Mack, Jonathan K Killian

Faculty, Staff and Student Publications

BACKGROUND: While many molecular assays can detect mutations at low tumor purity and variant allele frequencies, complex biomarkers such as tumor mutational burden (TMB), microsatellite instability (MSI), and genomic loss of heterozygosity (gLOH) require higher tumor purity for accurate measurement. Scalable, quality-controlled, tissue-conserving methods to increase tumor nuclei percentage (TN%) from tumor specimens are needed for complex biomarkers and hence necessary to maximize patient matching to approved therapies or clinical trial enrollment. We evaluated the clinical utility and performance of precision needle-punch enrichment (NPE) compared with traditional razor blade macroenrichment of tumor specimens on molecular testing success.

METHODS: Pathologist-directed NPE …

Faculty, Staff and Student Publications

BACKGROUND: Postsurgical pyoderma gangrenosum (PSPG) is a highly uncommon and unpredictable wound healing complication. Rapid progression of ulcers at incisions can cause unfettered dehiscence. Most commonly, PSPG involves breast procedures; however, in this work, we detail a case of a patient who developed PSPG 10 days postoperatively after penile inversion vaginoplasty.

METHODS: The patient in this case underwent a penile inversion vaginoplasty with orchiectomy in the standard fashion. She had no risk factors for PSPG. Following an uncomplicated hospital stay, the patient developed difficulty with pain control and increasing serous drainage on the 10th postoperative day. On readmission, the patient …

Promising Response Of Olaparib In Patient With Germline Atm-Mutated Metastatic Gastric Cancer, Kok Hoe Chan, Darius Rutazanaa, Curtis Wray, Nirav Thosani, Victor Yang, Putao Cen

Faculty, Staff and Student Publications

Gastric cancer ranks as the fifth leading cause of global cancer incidences, exhibiting varied prevalence influenced by geographical, ethnic, and lifestyle factors, as well as Helicobacter pylori infection. The ATM gene on chromosome 11q22 is vital for genomic stability as an initiator of the DNA damage response, and mutations in this gene have been associated with various cancers. Poly ADP-ribose polymerase (PARP) inhibitors, such as olaparib, have shown efficacy in cancers with homologous recombination repair deficiencies, notably in those with ATM mutations. Here, we present a case of a 66-year-old patient with germline ATM-mutated metastatic gastric cancer with very high …

Faculty, Staff and Student Publications

Introduction: Little is known about patient-reported outcomes (PROs) following abdominal trauma. We hypothesized that patients undergoing definitive laparotomy (DEF) would have better PROs compared to those treated with damage control laparotomy (DCL).

Methods: The DCL Trial randomized DEF versus DCL in abdominal trauma. PROs were measured using the European Quality of Life-5 Dimensions-5 Levels (EQ-5D) questionnaire at discharge and six months postdischarge (1 = perfect health, 0 = death, and < 0 = worse than death) and Posttraumatic Stress Disorder (PTSD) Checklist-Civilian. Unadjusted Bayesian analysis with a neutral prior was used to assess the posterior probability of achieving minimal clinically important difference.

Results: Of 39 randomized patients (21 DEF versus 18 DCL), 8 patients died (7 DEF versus 1 DCL). Of those who survived, 28 completed the EQ-5D at discharge (12 DEF …
