Leveraging Aspiring And Inspiring Mentorship Relationships To Promote Stem Persistence, Rayann K. Hoppe

Honors Thesis

While several mentorship interventions for STEM students already exist, persistence and retention in STEM fields remain relatively low. Additionally, there is limited research examining the intersections between aspiring (upward) and inspiring (downward) mentorship roles.

This article aims to address these gaps by examining existing literature and mentorship frameworks, with a focus on how mentorship dynamics influence STEM persistence. Two principal findings emerge from the literature: (1) effective mentorship should be conceptualized as an interconnected ecosystem rather than a hierarchical structure, and (2) the intersection of aspiring and inspiring roles contributes to the development of identity, self-efficacy, and a sense of …

Key themes that were identified in gifted programs include 21st-century skill development, project-based learning, and social-emotional …

The Impact Of Culturally Responsive And Inclusive Instructional Practices, Avril Baccam

Master's Theses & Capstone Projects

Culturally responsive and inclusive instructional practices are essential for supporting student engagement and participation in increasingly diverse elementary classrooms. However, some second-grade students do not experience equitable opportunities to engage in learning due to instructional practices that may not fully address cultural, linguistic, and learning differences. This inquiry-based research study aimed to examine second-grade teachers' perceptions of culturally responsive and inclusive instructional practices and their impact on student engagement and participation. The study also explored which instructional strategies teachers identify as most effective for promoting equitable engagement among diverse learners. A mixed-methods approach was utilized, including quantitative survey data and …

Schoolwide Pbis And Its Influence On Engagement And Discipline For Students With Disabilities, Morgan Peterson

Master's Theses & Capstone Projects

Positive Behavior Interventions and Supports (PBIS) is a framework adopted by schools to proactively teach and reinforce expected and prosocial student behaviors. The framework is implemented across three tiers and provides opportunities for data collection to support decision-making at each level of intervention. PBIS emphasizes clear behavioral expectations, consistent reinforcement, and systematic responses to behavior within a schoolwide system (Simonsen et al., 2022; Meyer et al., 2021). Previous research suggests that when PBIS is implemented across all three tiers, the use of exclusionary disciplinary practices decreases for all students, with particularly notable effects for students with disabilities who are supported …

The purpose of this study was to understand how engagement, persistence, and problem-solving developed over time through play-based experiences and teacher facilitation. Data were collected over a four-week period using multiple tools, including structured observation checklists, frequency and duration recording sheets, anecdotal field notes, and reflective journal entries. The findings of this study suggest that play-based learning supported the development of early academic-related learning behaviors, as the child demonstrated increased engagement, improved persistence, and …

The Impact Of Mindfulness Strategies In An Elementary Classroom, Trinity Lawless

Master's Theses & Capstone Projects

School districts across the globe have adopted social-emotional initiatives throughout their schools to better the mental health of students and instill crucial soft skills within them. Implementing mindfulness strategies is one way that teachers are helping their students become more emotionally self-regulated learners. Although there is a plethora of research surrounding mindfulness, research on the specific mindfulness strategies that work best and the ones that students prefer is missing from the existing research. To mend this research gap, the current researcher sought to discover how mindfulness strategies impact students’ overall mindfulness score, what strategies are most beneficial, and which strategies …

Explicit Phonological Awareness Vs. Classroom Literacy Instruction, Aaron Sue Grahlman

Master's Theses & Capstone Projects

The study explored the effectiveness of explicit phonological awareness instruction compared with traditional classroom literacy instruction in supporting early reading development among kindergarten students, particularly those at risk for reading difficulties. Drawing on Formative Assessment System for Teachers (FAST) data from two cohorts, the results showed varying degrees of difference in overall reading proficiency between the two instructional approaches. These findings indicate that while both approaches support student literacy growth, early, systematic instruction in phonological awareness yields more rapid initial gains and a higher proportion of students meeting benchmarks. These findings suggest that implementing targeted phonological strategies can lead to …

The Impact Of Structured Reflective Journaling On Self-Efficacy In Early-Career Teachers, Ashley Van Dusseldorp

Master's Theses & Capstone Projects

Teacher self-efficacy is a critical factor influencing instructional effectiveness, classroom management, and teacher retention, yet many educators in their first five years of teaching report low confidence in their professional abilities as they navigate the complexities of the classroom. This lack of confidence can negatively impact instructional decision-making, classroom practices, and long-term commitment to the profession. The purpose of this inquiry-based research study was to examine the impact of a structured reflective journaling intervention on the self-efficacy of new teachers with fewer than five years of teaching experience. Using a mixed-methods design, participants completed pre- and post-intervention self-efficacy surveys and …

Improving Bullying Victimization And Supports For Autistic Students, Sidney Swanson

Bullying and peer victimization remain persistent concerns for students with autism spectrum disorder (ASD), who experiences higher rates of peer exclusion, rejection, and social isolation than their neurotypical peers. These experiences can negatively affect school engagement, emotional well-being, peer relationships, and long-term mental health outcomes. This practitioner inquiry study examined how classroom based social emotional learning (SEL) and inclusion strategist influenced peer relationships, student belonging, and bullying related behaviors for students with autism in an elementary school setting. This study was conducted over a six-week period in one first grade general education classroom and one Strat II ID/ LD classroom …

Co-Teaching Classroom Management And Relationships: Impact On Ell Student Engagement And Achievement In 5th Grade Ela, Jesse Strong

Master's Theses & Capstone Projects

This study examines how co-teaching influences English Language Learner (ELL) engagement, behavior, teacher-student relationships, and academic achievement in a fifth-grade ELA classroom. As classrooms become more diverse, teachers need strategies that support language development while still holding students to grade-level expectations. Co-teaching, where a general education teacher works alongside a support teacher, allows for shared planning, instruction, and assessment to better meet student needs. The purpose of this study was to explore how different co-teaching approaches affect student engagement, confidence, classroom behavior, and learning outcomes. Data were collected through classroom observations, student work and performance data, and teacher reflections. Findings …

Precision Or Invasion? Mapping The Personalization Paradox, Shyamala N. Chalakudi, Gnana Bharathy

Journal of Applied Marketing Theory

AI-driven personalization has transformed consumer engagement, yet existing research offers no systematic way to determine when personalization shifts from helpful to intrusive. Current research and models explain privacy concerns or expectancy violations but do not measure the point at which personalization triggers user discomfort, creating the personalization paradox. This study introduces the Discomfort Threshold Assessment & Measurement (DTAM) framework, a conceptual model that identifies and evaluates this threshold by integrating Dual Process Theory, Expectation Violation Theory, and Privacy Calculus Theory. DTAM distinguishes between affective discomfort reactance and cognitive discomfort reactance and outlines how these constructs could, in future empirical studies, …

Telomerase Knockout In Myeloid Cells Predisposes Mice To Foam Cell Formation, Dyslipidemia, Lung Fibrosis, And Cardiac Dysfunction, Zhanguo Gao, Yongmei Yu, David Wiggins, Eva M Sevick-Muraca, Mikhail G Kolonin

The Brown Foundation: Institute of Molecular Medicine

Aging-associated changes in myeloid cells are incompletely understood. One of the culprits of aging is the downregulation of the Tert gene coding for the catalytic subunit of telomerase. Studies of mouse models with Tert knockout (KO) in specific cells have revealed the importance of the telomere-independent noncanonical function of TERT in supporting mitochondrial metabolism and protection from cell senescence. To investigate the role of TERT in myeloid cells (MCs), we analyzed mice with Tert KO in the LysM+ lineage, indelibly labeled with membrane green fluorescent protein (mG). Macrophage numbers and properties in various organs were compared. Changes in the vasculature, …

Faculty, Staff and Student Publications

Introduction: We investigated the association between traumatic brain injury (TBI) and incidence of early-onset dementia (EOD) versus late-onset dementia (LOD).

Methods: We included 501,710 UK Biobank participants (average age 56.5). Over a median 13.6 years of follow-up, 836 developed EOD (before 65) and 8947 developed LOD (after 65). We estimated hazard ratios (HRs) for TBI's association with EOD and LOD using Cox proportional hazard models with TBI as a time-varying exposure and coefficient.

Results: TBI was associated with higher risk of both EOD (HR: 4.06 [95% confidence interval: 3.13, 5.26]) and LOD (HR: 2.51 [2.31, 2.72]. Among participants included in …

Continuous Versus Bolus Norepinephrine Administration To Treat Hypotension After Induction Of General Anaesthesia In Low-To-Moderate Risk Noncardiac Surgery Patients: A Randomised Trial, Kristen K Thomsen, Finn Külls, Christina Vokuhl, Linda Krause, Dominik Müller, Max Bossemeyer, Mirja Wegge, Alina Kröker, Alina Bergholz, Christian Zöllner, Daniel I Sessler, Bernd Saugel

Faculty, Staff and Student Publications

Background: Hypotension after induction of general anaesthesia (postinduction hypotension) is common in patients undergoing noncardiac surgery and frequently requires treatment with vasopressors such as norepinephrine. We tested the hypothesis that giving norepinephrine continuously using a syringe infusion pump, compared with giving it as repeated manual boluses, reduces postinduction hypotension within 15 min after starting induction of general anaesthesia in low-to-moderate risk noncardiac surgery patients.

Methods: Patients undergoing elective noncardiac surgery were randomised to either continuous norepinephrine infusion or manual bolus norepinephrine administration intravenously during induction of general anaesthesia. In both groups, norepinephrine was administered through a peripheral venous catheter. Blood …

Background: Titanium implants are considered the gold standard for oral rehabilitation; however, zirconia implants have emerged as a metal-free alternative with promising esthetic and biological properties. Despite these advantages, limited evidence is available regarding their long-term fatigue behavior and fracture resistance.

Material and methods: In this in vitro experimental study conducted at São Paulo State University (UNESP), Brazil, forty implants were divided into two groups (n = 20): zirconia implants (ZZ) and titanium implants (TZ) (4.1 × 10 mm). Implants were embedded in polyurethane blocks according to ISO 14801:2016 specifications. Monolithic zirconia crowns were fabricated using CAD/CAM technology and cemented …

Performance Reviews In Project-Based Engineering Firms: Toward A More Holistic And Development-Oriented Approach, Xun He

Harrisburg University Dissertations and Theses

Performance reviews are widely used in engineering consulting firms to evaluate employee contributions and determine compensation and promotion decisions. However, research has shown that traditional review systems may overemphasize measurable technical results while overlooking collaboration, leadership, and innovation. In project-based engineering environments, where employees work across multiple teams and stakeholders, this structure may not fully reflect the nature of daily work. This qualitative phenomenological study explored how early-career engineers in project-based engineering consulting firms experienced performance review practices. Data were collected through semi-structured interviews with 15 engineers working in consulting firms. The study examined participants’ perceptions of fairness, completeness, and …

Elementary Abelian Sylow Subgroups Of The Multiplicative Group, Geremías Polanco

Mathematics Sciences: Faculty Publications

Erdős and Pomerance have shown that 𝜑⁡(𝑛) typically has about 1 2 ⁢(log⁡log⁡𝑛)2 distinct prime factors. More precisely, 𝜔⁡(𝜑⁡(𝑛)) has normal order 1 2 ⁢(log⁡log⁡𝑛)2. Since 𝜑⁡(𝑛) is the size of the multiplicative group (𝐙/𝑛⁢𝐙)×, this result also gives the normal number of Sylow subgroups of (𝐙/𝑛⁢𝐙)×. Recently, Pollack considered specifically noncyclic Sylow subgroups of (𝐙/𝑛⁢𝐙)×, showing that the count of those has normal order log⁡log⁡𝑛/⁢log⁡log⁡log⁡𝑛. We prove that the count of noncyclic Sylow subgroups that are elementary abelian of a fixed rank 𝑘 ≥2 has normal order 1 𝑘⁢(𝑘−1) ⁢log⁡log⁡𝑛/⁢log⁡log⁡log⁡𝑛. So for example, (typically) among the primes p for …

Do Purpleair Monitors Democratize Data For The Environment?, Christopher Rick, Kyla Lorden

Student Publications

PurpleAir monitors may serve a vital role in marginalized or under-monitored communities nationwide. These low-cost monitors—roughly $300—give communities the ability to monitor their air quality at local geographies in ways that are infeasible for expensive, regulatory-grade air monitors. They also have the potential to aid community advocacy efforts around environmental and transportation policy by giving community members literal ownership over the monitoring, including precise locations, and philosophical ownership over the advocacy efforts. To determine the potential democratization of air quality data by PurpleAir monitors in socially disadvantaged communities, we analyze the sociodemographic characteristics of neighborhoods with PurpleAir monitors. We find …

The Importance Of Body Size And Spatial Scale In Modeling Winter Bird Distributions, Carissa M. Mobley

Student Publications

Birds’ annual cycles include biologically linked breeding and non-breeding seasons, yet most research and bird atlases focus exclusively on the breeding season. There have been very few winter bird atlas projects in North America, and none have been published for the northeastern United States. Short daylight hours and harsh weather limit winter survey coverage, making species distribution models (SDMs) essential for addressing spatial gaps.

I evaluated the optimal spatial scale for SDMs across bird species differing in body size and tested whether optimal scale varies with body mass. Using 16,967 eBird checklists collected during the first winter survey period (December …

"Nobody Forced My Mom To Stay Home": College Men’S Perspectives On Parental Leave, Marisa Conners

Student Publications

From "The Second Shift" to Claudia Goldin’s Nobel Prize-winning research on women in the labor market, the inequities affecting women in the labor market have been widely documented. However, progress on this issue has been largely one-sided on behalf of women, perpetuating gender inequality. The goal of my research is to understand how social subgroup values influence male-identifying Gettysburg College students’ predictions on how they will engage with parental leave. This project gathered information on ways to increase male uptake of parental leave, which, if implemented, will help improve gender equity in the labor market.

How are male-identifying Gettysburg College …

Jdm And The Formation Of Japan’S Underground Car Culture: Street Racing, Identity, And Regulation, Lizhou Chen

Student Publications

Japan’s underground car culture is often associated with street racing, JDM, and modified cars, but these visible features developed from broader economic, social, and regulatory conditions. This paper argues that Japan’s underground car culture was shaped by three factors: postwar economic growth that made mass car production feasible, social identity and status attached to car type and driving behavior, and government regulation of the road system and driving habits that forced reckless driving into less visible times and locations. By examining car ownership, kei cars, youth self-expression, gendered meanings of vehicles, road design, and moral expectations around safe driving, this …

Blessing Or Curse? Natural Resources And Women’S Political Empowerment In Post-Conflict States, Katelyn L. Laplaunt

Student Publications

The end of a civil war represents an opportunity for women to gain political power and improve their societal status. If women are systematically constrained from gaining this power, they are losing a valuable chance to improve levels of gender equality. Little research thus far has focused on how the post-conflict period might be impacted by a country’s natural resource wealth. This study aims to fill this knowledge gap by exploring how a country’s dependence on natural resources might influence women’s political empowerment in post-conflict societies. I argue that countries that rely more heavily on natural resources as a source …
