Beginning Science Teachers' Subject Matter Knowledge, Misconceptions, And Emerging Inquiry-Based Teaching Practices (Poster), Elizabeth B. Lewis, Ana Rivero, Lyrica Lucas, Aaron Musson, Amy Tankersley

Department of Teaching, Learning, and Teacher Education: Presentations

When we investigated the relationship of science subject matter knowledge with subsequent inquiry-based instruction, we found on average that over the induction period the MAT teachers taught lessons using more inquiry-based instruction at twice the rate of the average teacher prepared in the undergraduate program without an undergraduate degree in science. Specifically, new science teachers from the MAT program with an undergraduate degree in chemistry were better prepared to use an inquiry-based approach to teaching chemistry. Our research of our two teacher preparation programs contribute a reliable design for producing highly-qualified teachers who can provide active, engaging, constructivist learning opportunities …

A Systems Biology Approach To Understanding The Pathophysiology Of High-Grade Serous Ovarian Cancer: Focus On Iron And Fatty Acid Metabolism., Anna Konstorum, Miranda L Lynch, Suzy V Torti, Frank M Torti, Reinhard C Laubenbacher

Faculty Research 2018

Ovarian cancer (OVC) is the most lethal of the gynecological malignancies, with diagnosis often occurring during advanced stages of the disease. Moreover, a majority of cases become refractory to chemotherapeutic approaches. Therefore, it is important to improve our understanding of the molecular dependencies underlying the disease to identify novel diagnostic and precision therapeutics for OVC. Cancer cells are known to sequester iron, which can potentiate cancer progression through mechanisms that have not yet been completely elucidated. We developed an algorithm to identify novel links between iron and pathways implicated in high-grade serous ovarian cancer (HGSOC), the most common and deadliest …

Poor Sleep As A Predictor Of Nssi And Suicide Ideation In Adolescents, Shelby Leeann Bandel

Masters Theses & Specialist Projects

Despite becoming a greater public health concern, the suicide rate among adolescents has not decreased significantly in recent years (Center for Disease Control and Prevention [CDC], 2015). In fact, suicide is the second leading cause of death for individuals between 12-18 years (CDC, 2015). Nonsuicidal self-injury (NSSI), the deliberate destruction of one’s own body tissue without suicidal intent and for reasons not socially sanctioned (Nock, 2009), has been identified as a robust predictor of suicide, above and beyond other risk factors such as depression and hopelessness (Asarnow et al., 2011; Guan, Fox, & Prinstein, 2012). Therefore, understanding risk factors for …

First, laser pulses at selected fluences were directly focused on the NiTi surface, which generated pressure pulses of up to …

Grandfamilies In Vietnam: Grandparents’ Engagements In Grandchildren’S Academic Performance At School, Nga Thi Ngoc Nguyen

Masters Theses & Specialist Projects

In Vietnam, the number of grandparents who become full -time surrogate parents to their grandchildren has significantly increased. When parenting is left to grandparents, they play the same role as biological parents. They significantly affect the educational functioning, developmental outcomes, and well-being of their grandchildren. Using data from in-depth interviews with 16 participants who are raising their grandchildren, the current study provides insight into children’s education in the grandparents-headed households in Vietnam. The more grandparents are involved in their grandchildren’s educational process, the more likely their grandchildren are to achieve academic success. I have found that there is a strong …

A Climatology Of Convective And Non-Convective High-Wind Events Across The Eastern United States During 1973-2015, Victoria Murley

Masters Theses & Specialist Projects

High-wind events (HWE) occur across every region of the United States (U.S.) and result in hundreds of fatalities, as well as thousands of dollars in damages annually. HWEs are classified as sustained high-winds or high-wind gusts and can be generated from convective or non-convective weather systems. This study investigates high-wind observations across the eastern U.S. during a 43-year climatological period (1973-2015) for spatial and temporal variations in wind speed and direction. Hourly surface wind observations were gathered from the National Centers for Environmental Information Data Center Integrated Surface Database (NCEI-ISD). This dataset includes qualitycontrolled wind observations from 391 first-order weather …

Characterization Of Eight Potentially Hazardous Near Earth Asteroids: Rotation Period Analysis And Structure Modeling Via Light Curve Inversion Techniques, Stacy Jo Hicks

Masters Theses & Specialist Projects

The term “homeland security”, seems to have become synonymous with terrorism in the minds of the general public. However, there are other threats to the security of the United States homeland that can be just as, if not more, devastating than terrorism. Included among these other threats is the potential of an asteroid collision with Earth. Historically, asteroid impact events have been responsible for the devastation of our planet and many of the mass extinction events encountered throughout the geologic record. Knowledge of physical parameters such as structure and rotational dynamics of the asteroid are critical parameters in developing interception …

Photochemical Investigation Of High-Valent Metal-Oxo Intermediates Containing Corrole And Light-Harvesting Porphyrin Ligands, Jonathan Malone

Masters Theses & Specialist Projects

In enzymatic and synthetic catalytic oxidations, high-valent iron-oxo intermediates play a vital role as the active oxidant. In this regard, many synthetic metal catalysts are designed as biomimetic models to resemble the active site of Cytochrome P450 enzymes (P450) which are the predominant oxidation catalysts in nature. Vitamin B12 cofactors, with a corrole-like structure corrin, are also utilized in some of the more difficult reactions in nature such as rearrangement and reductase reactions.

In this work, application of the promising photochemical method to corrolecontaining ligands systems showed much success in the generation of manganese(V)-oxo corrole intermediates using two electron-deficient corrole …

An Evaluation Of Deterrent Methods Utilized To Prevent Crop Raiding By African Elephants (Loxodonta Africana) In The Kasigau Wildlife Corridor, Kenya, Rebecca Lynn Von Hagen

Masters Theses & Specialist Projects

Escalating human elephant conflict (HEC) continues to be a contributing factor

towards elephant decline, and crop raiding is the most common form of negative

human-elephant interactions. For communities that cannot reverse or prevent crop

raiding, it is necessary to contain HEC events through deterrent measures. Few

deterrent measures exist that combine practicality and affordability while also

preventing habituation by elephants. This project focused on comparing the efficacy of

deterrent methods to assess which was the most successful at preventing elephants

from entering crops in the farming community of Sasenyi, Kenya. In this paired-control

study, four deterrent methods were evaluated: acacia …

Health Fetishism Among The Nacirema: A Fugue On Jenny Reardon’S "The Postgenomic Condition: Ethics, Justice, And Knowledge After The Genome" (Chicago University Press, 2017) And Isabelle Stengers’ "Another Science Is Possible: A Manifesto For Slow Science" (Polity Press, 2018), Scott F. Gilbert

Biology Faculty Works

Personalized medicine has become a goal of genomics and of health policy makers. This article reviews two recent books that are highly critical of this approach, finding their arguments very thoughtful and important. According to Stengers, biology’s rush to become a science of genome sequences has made it part of the “speculative economy of promise.” Reardon claims that the postgenomic condition is the attempt to find meaning in all the troves of data that have been generated. The current paper attempts to extend these arguments by showing that scientific alternatives such as ecological developmental biology and the tissue organization field …

Epigenomics And Metabolomics Reveal The Mechanism Of The Apoa2-Saturated Fat Intake Interaction Affecting Obesity, Chao-Qiang Lai, Caren E Smith, Laurence D Parnell, Yu-Chi Lee, Dolores Corella, Paul Hopkins, Bertha A Hidalgo, Stella Aslibekyan, Michael A Province, Devin Absher, Donna K Arnett, Katherine L Tucker, Jose M Ordovas

Open Access Publications

Background: The putative functional variant -265T>C (rs5082) within the APOA2 promoter has shown consistent interactions with saturated fatty acid (SFA) intake to influence the risk of obesity.

Objective: The aim of this study was to implement an integrative approach to characterize the molecular basis of this interaction.

Design: We conducted an epigenome-wide scan on 80 participants carrying either the rs5082 CC or TT genotypes and consuming either a low-SFA (<22 g/d) or high-SFA diet (≥22 g/d), matched for age, sex, BMI, and diabetes status in the Boston Puerto Rican Health Study (BPRHS). We then validated the findings in selected participants in the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) Study (n = 379) and the Framingham Heart Study (FHS) (n = 243). Transcription and metabolomics analyses were conducted to determine the relation between epigenetic status, APOA2 mRNA expression, and blood metabolites.

Results: In the BPRHS, we identified methylation site cg04436964 as exhibiting significant differences between CC and TT participants consuming a high-SFA diet, but not among those consuming low-SFA. Similar …

Exploring Standardized Patients’ Perspectives On Working With Medical Students, Samantha Starr, Margaret M. Plack, Karen Lewis, Benjamin Blatt

GW Research Days 2016 - 2020

Little is known about how working with emerging medical professionals affects Standardized Patients’ (SPs’) professional identities, yet understanding the SP-medical student interaction could be useful for screening SPs, supporting SP professional identity formation, and bridging the SP and medical student cultures. This project provides the unique perspective of SPs involved in the growth of medical students into physicians.

Qualitative methods were used to understand the SPs’ perspectives. Two researchers, without evaluative relationships with the SPs, conducted 2 one-hour focus group interviews (n=3; n=9) using a semi-structured interview protocol. Interviews were audio-recorded and transcribed verbatim. Three researchers independently analyzed the transcripts …

Development Of A Rapid Diagnostic Assay For The Colorimetric Detection Of Bacterial And Viral Pathogens Using Loop-Mediated Isothermal Amplification Coupled With A Peptide Nucleic Acid And Gold Nanoparticle Reporter System, William Brown

All NMU Master's Theses

Detection of pathogenic agents remains pivotal to the control and prevention of infectious disease. While diagnostic methods continue to break barriers, the need for accurate, sensitive, and rapid methods persists. Current methods for pathogen detection, including culture, immunochemical, or molecular-based techniques, are subject to significant limitations that restrict their clinical utility. Point-of-care (POC) tests have received attention for the diagnostic screening of infectious disease, with benefits of simplicity, affordability, and convenience. This study describes the development of a novel loop-mediated isothermal amplification (LAMP) reaction followed by a peptide nucleic acid (PNA) probe and gold nanoparticle (AuNP) detection system that results …

Development Of The Pain Response Style Inventory: A New Measure For Examining Ambivalence Toward Engaging In Behavioral Treatments For Chronic Pain, Robert Bailey

Psychology ETDs

Over the previous half-century, the framework for chronic pain management has expanded beyond the biomedical perspective to include psychosocial treatments that fall under the cognitive-behavioral tradition. Chronic pain patients, however, tend to endorse the biomedical model, perceiving pain as a problem that requires medical interventions. Enhancing motivation to engage in cognitive-behavioral treatment has therefore been a major theoretical focus in the research literature, much of which has been informed by Motivational Interviewing (MI) and the Transtheoretical Model. At present, however, there is a paucity of empirical evidence supporting motivational enhancement in this context. Furthermore, the research literature has largely overlooked …
