Math Leaders’ Perceptions Of Social Justice Pedagogy: Implications For Professional Development On Teaching Mathematics For Climate And Environmental Justice, Angela M. Allen

Theses and Dissertations

Two significant crises facing communities of color are climate and environmental injustices (Schlosberg & Collins, 2014) and the achievement gap in standardized test performance as an impact of inequitable educational experiences rooted in a history of social inequities (Agarwal, 2011; Milner, 2020). Previous studies on teaching mathematics for social justice demonstrate positive student outcomes from this practice (Berry, 2008; Gutstein, 2006). Existing literature also points to benefits when focusing on a specific social justice topic during mathematics instruction (Bartell, 2013; Stocker, 2012). However, few studies focus on math leaders’ perceptions of teaching mathematics for climate and environmental justice (TMCEJ).

A Case Of Misalignment Of Reasoning, Affect, And Performance In The Transition-To-Proof, V. Rani Satyam

Journal of Mathematics and Science: Collaborative Explorations

Learning how to prove is known to be difficult for undergraduate students. Understanding students’ growth in the multiple arenas that make up proving is crucial for supporting them. Across four interviews over a semester, I examine one student who showed growth in his reasoning but whose proofs were still incorrect, yet he showed high levels of positive affect including confidence throughout. Investigating this single-subject case serves as an example of the interplay between development and performance. The question of whether we can say this student is a better prover than before––fundamentally, how to weigh reasoning versus affect versus performance––motivates the …

Connected At A Distance: Experiences And Efforts Within A Synchronous, Online Mathematics Specialist Program, Laura E. Bitto, Pamela E. Johnson, Beth Terry

Journal of Mathematics and Science: Collaborative Explorations

Online learning offers flexibility and convenience to students regardless of their proximity to a traditional campus. However, online programs can also feel isolating. Beth, a mathematics specialist candidate, completed a graduate program while living 7000 miles and seven time zones away from her instructor and peers. Through intentional planning by instructors, Beth found community by making personal connections, celebrating life experiences, and sharing a passion for mathematics education with her peers. Furthermore, Beth felt empowered to take academic risks and expose professional vulnerabilities in the learning community. The instructors within the program valued learning as a social construct and therefore …

The Student Experience Of Higher Education During The Covid-19 Pandemic: How Class And Race Shape Socially Distanced Learning At A Public University, Alice M. Quach

Theses and Dissertations

While prior research has examined trends toward growing uncertainty and precarity for young adults within the economy and higher education, the COVID-19 pandemic appears to be exacerbating these existing inequalities and risks. Drawing from 30 semi-structured in-depth interviews with college students at a large Southern and urban public university, this study examines how the COVID-19 pandemic is affecting students’ learning experiences, and how those experiences are differentially shaped, in turn, by their class and race. This exploratory research illuminates our understanding of the multiple mechanisms by which the COVID-19 pandemic is shaping existing inequalities in the higher education system, mostly …

Stigmatizing Labels, School Bonds, And Capital In The School Reentry Experiences And Educational Outcomes Of Justice-Involved Youth, Peter S. Willis

Theses and Dissertations

Research indicates that justice-involved youth who reenter public and alternative schools following contact with the juvenile justice system struggle to find a place in the school community and complete their educations. Because educational attainment affects recidivism rates, successful school reentry for justice-involved youth presents important research questions for policy and practice. This study examined school reentry through cases studies of adults who had been justice-involved youth and had experienced school reentry following contact with the juvenile justice system. Study participants’ school reentry experiences were examined through a theoretical framework comprised of labeling, social control, and field theories. Findings suggest that …

The Impact Of Latent Print Processing On Firing Pin And Breechface Impressions During Firearm Examination, Brittany B. Harrington

Master of Science in Forensic Science Directed Research Projects

Latent prints can be a valuable source of forensic evidence when solving a crime. They can verify if a person was at a specific scene, identify unknown individuals to connect them to a scene, and help to corroborate eyewitness accounts. Latent prints, however, are not always visible until they have undergone enhancement or visualization techniques. When fired cartridge cases are suspected of containing latent prints, they are brought in for latent print processing before any firearm analysis is performed. As a result, these cartridges are often coated in various residues or dyes when they arrive for firearm examination. In response, …

The Buffering Effects Of Resilience On Alcohol Use: A Phenotypic And Genotypic Investigation, Shannon Cusack

Theses and Dissertations

The college years encompass a time of vulnerability for problematic alcohol use/alcohol use disorder (AUD) and exposure to traumatic events (TE), which is a transdiagnostic risk factor for AUD, posttraumatic stress disorder (PTSD), and comorbid AUD-PTSD. However, not all who experience a TE develop these disorders, highlighting the need to identify factors that impact post-trauma outcomes. Resilience has been shown to be associated with lower alcohol consumption and related problems following TE, though the buffering effects of resilience on alcohol use have not yet been examined. Further, twin studies demonstrate that resilience is moderately heritable, but further research is needed …

Evaluation Of Five Methods To Develop Latent Prints On Thermal Paper, Jenna Pregent

Master of Science in Forensic Science Directed Research Projects

Forensic latent fingerprint laboratories determine the proper techniques for fingerprint visualization based on the substrates upon which they are deposited. Typical forensic analysis of thermal paper evidence involves the application of ninhydrin and/or 1,2-indanedione dissolved in a polar solvent. However, polar solvents create an undesirable reaction with the thermal paper’s internal properties and often lead to discoloration of the evidence. When this occurs, not only are the fingerprints less likely to be visible due to the loss of contrast, but the evidentiary print on the receipt may be lost entirely. This research sought to compare five development methods to determine …

Identification And Optimization Of Mirna Biomarkers For Body Mass Index (Bmi) Estimation In Forensic Samples, Jennifer J. Shealy

Master of Science in Forensic Science Directed Research Projects

DNA profiles do not provide as much evidentiary value when either all known samples can be excluded or when there is no known suspect. DNA phenotyping is a technique used for investigative purposes to predict externally visible characteristics (EVCs) based on specific markers found in the genome. Most phenotyping panels are currently restricted to markers stable over a lifetime within an individual and are not able to predict environmental or metabolic impacts on EVCs. It is known that miRNA expression levels change due to environmental and metabolic factors, such as BMI, and research has proven associations between circulating plasma miRNAs …

Policy And Practice Brief 6: Considerations For Using Access Test Scores In Decision-Making, Carolyn N. Waters, Merc English Learner Research & Evaluation Team, Virginia Commonwealth University

MERC Publications

Since the implementation of The No Child Left Behind Act of 2001 (NCLB), all students identified as English learners (ELs) in U.S. public schools have been required to take an annual assessment of English language proficiency (ELP) for federal accountability. Virginia and many other state education agencies (SEAs) use the WIDA ACCESS for ELLs© test (ACCESS), not only to comply with this mandate, but also to inform a variety of high-stakes decisions for EL instruction, such as determining when multilingual learners have reached English proficiency, deciding about Language Instruction Educational Program (LIEP) entry and exit, informing classroom instruction and assessment, …

Untitled, Lihua Yu

Theses and Dissertations

The library stores up my favorite memories. Sometimes I look for a book by its title, author or publisher, sometimes by its designer; other times I just wander around different sections and enjoy encountering books by chance. As an object, a book is eternal while I am a passer-by. I believe in the connection between people who read the same books and watch same films with me. This untitled book is a thankful catalog, documented in a straightfoward way

The Harm In Seeking Care: Assessing The Relationship Between Healthcare Discrimination And Healthcare Avoidance Behaviors In The Past Year And Since The Start Of The Coronavirus Pandemic In A Transgender And Gender Independent Sample, Kyle L. Mason

Theses and Dissertations

Background: Gender minorities encounter a myriad of barriers to accessing general and gender affirming healthcare. Financial disparities impacting affordability of healthcare costs and insurance-based denials for gender-affirming care are among prominent barriers discussed. Considerations of the prevalence of stigma, discrimination, and erasure of gender minority identities must not be neglected when seeking to understand healthcare accessibility and utilization in this population. Previous researchers have examined gender minority patients’ experiences of discrimination in healthcare settings and delaying care due to fear of discrimination. There is a dearth of knowledge about the relationship between lifetime exposure to varied forms of healthcare discrimination …

Cognitive Debiasing Intervention For Assessment Of Prolonged Grief Disorder, Farah Aslanzadeh, M.S.

Theses and Dissertations

Cognitive debiasing is an approach to reducing diagnostic decision-making errors resulting from the misuse of cognitive heuristics and biases. This study built on prior research that has successfully used a multi-modal debiasing approach to reduce diagnostic errors. Clinicians were recruited and randomized into a general presentation on the changes in the stress and trauma section of ICD-11 (including the diagnostic criteria of prolonged grief disorder [PGD]) or the same general presentation plus and a cognitive debiasing intervention for PGD. All clinicians were then asked to diagnose three patient vignettes in which biases/potential decision-making errors were embedded in the text. Results …

A Mixed Methods Approach To Examine Racial Disparities In Adherence To Surveillance Mammography Among Breast Cancer Survivors, Megan C. Edmonds

Theses and Dissertations

PURPOSE: Annual surveillance mammography is a critical part of routine cancer care for breast cancer (BC) survivors; reducing mortality by 39%. However, disparities exist with regard to adherence to surveillance mammograms among BC survivors; Black women are 44% less likely to adhere than their White counterparts. Despite the existence of this racial disparity for over a decade, little is known about factors that explain reasons for Black BC survivors’ non-adherence. This is because most studies have not evaluated the role of healthcare delivery or psychosocial factors. Guided by the Behavioral Model for Vulnerable Populations, the purpose of this mixed methods …

A Non-Inferiority Randomized Controlled Trial Comparing Behavioral Sleep Interventions In Women Veterans: A Secondary Analysis Of Pain Outcomes, Scott Ravyts

Theses and Dissertations

Women are disproportionally more likely to experience both insomnia and chronic pain. While these two conditions frequently co-occur, a wealth of literature suggests that insomnia is a stronger predictor of pain than pain is of insomnia. Preliminary research indicates that sleep apnea may also lead to adverse pain outcomes, with the combination of insomnia and sleep apnea contributing to an adverse synergistic effect on pain. Despite the clinical implications of such findings, knowledge regarding the interrelations between sleep disorder complexity and pain remain limited, especially among women. Additionally, interventions seeking to improve pain by targeting insomnia have yielded inconsistent results …

An Exploration Of Teacher Residents’ Perception Of Culture And Their Use Of Culturally Responsive Pedagogy, Jodi Larson

Theses and Dissertations

Urban teacher residency (UTR) programs place residents in urban schools labeled “hard-to-staff” or “under-resourced.” Enrollment in residency schools tends to be majority Brown or Black students from various cultures. Teacher residents are from diverse backgrounds and races who have a commitment to teach in Title 1 schools with the support of a residency program that coaches them how to teach using culturally relevant pedagogy. Their journeys are unique from typical student teaching experiences because they co-teach with an experienced teacher for a full school year while attending university classes on pedagogy and theory. This qualitative case study followed seven elementary …

Modeling Substance Use And Mental Disorder Comorbidity Using Latent Variable And Network Approaches, Courtney T. Blondino

Theses and Dissertations

Consequently, detailing and addressing SUD and comorbid SUD represent an important goal to improve the health of Americans.

Objective. The research goal of this dissertation was to characterize the comorbidity between substance use, including tobacco use, and mental disorder symptoms measured as negative affect and externalizing symptoms in a population-based sample using latent variable and network approaches.

Methods. Waves 1 – 3 from the Population Assessment of Tobacco and Health Study were used. …

Genetics And Alcohol Interventions In Youth, Zoe E. Neale

Theses and Dissertations

Alcohol is the most commonly used substance among youth, and risky alcohol use is associated with harmful consequences such as accidents, academic consequences, and physical and emotional health problems. Alcohol use disorders are approximately 50% heritable, yet most efforts to prevent and intervene upon youth alcohol use focus only on environmental factors. Furthermore, current prevention and intervention programs tend to have modest effects and are not uniformly effective for all individuals. Gene-by-intervention (GxI) studies offer an opportunity to expand current understanding of interventions by examining whether underlying genetic risk may contribute to differential program effects. Much of the current GxI …

Owning Our Story: An Interior Exploration To Foster Self-Reflection, Hannah Bulow

Theses and Dissertations

With emerging technologies in the 21st century, Millennial and Gen Z adults have a complicated relationship with these new technologies when it comes to creating and sustaining personal relationships (Dalessandro, 2018). When persons aged 18-35 forged new relationships without the presence of technology, relationships were more organic, natural, and led to less conflicts. Neuroimaging of the brain has also shown that neurocognitive development during early adolescence and adulthood contributes to self-consciousness and vulnerability. Adolescents are called to develop their own identity separate from their parents and understanding how others are actually evaluating them (Sebastian, 2008)

Brene Brown states that most …

Interpersonal Trauma And Mental Health Among Lgbq+ College Students: Examining Social Support And Trauma-Related Drinking As Mediators, Eryn Delaney

Theses and Dissertations

Despite the increased risk of childhood, adulthood, and lifetime interpersonal trauma among LGBQ+ individuals, existing research that has examined the influence of interpersonal trauma on mental health has primarily focused on LGBQ+ adolescents and samples of LGBQ+ community-based adults, and less on LGBQ+ emerging adults in college. Additionally, limited work has focused on mechanisms that might explain the relations between these variables. Thus, the current study tested the relations between interpersonal trauma (i.e., childhood sexual abuse, adulthood sexual victimization, and lifetime physical assault and IPV) and mental health outcomes (i.e., anxiety symptoms, depressive symptoms, and PTSD symptoms), and examined social …

Grief, Loss, And Climate Change: Validation Of A Solastalgia Scale, Claire Luce

Theses and Dissertations

Climate change has been identified as a defining issue of this century (United Nations, n.d.). Climate change impacts human wellbeing including mental health. While much research has focused on the way that the effects of climate change cause increases in common mental disorders, mental health is not just the absence of these disorders (World Health Organization, 2014). Non-pathologized mental health responses to climate change, such as the grief and loss that results from climate change impacts, are a growing consideration for researchers. Solastalgia, or the distress experienced in the absence of the solace once provided by the environment in the …
