Dietary Intake And Changes In Body Composition Over The Course Of One Season In Ncaa Division 1 Football Players, Blayke W. Harrison

Master's Theses

Energy intake and macronutrient composition of an athlete’s diet is highly important when considering performance. Additionally, having a favorable body composition (i.e. low levels of fat mass and high levels of lean body mass) is crucial in high-level athletes.The role of nutrition-related support personnel is highly needed by many collegiate athletics programs to achieve these outcomes, yet this resource seems to be undervalued and underused in many settings. The present thesis investigates the effects of providing nutritional support to improve dietary habits and compare changes in specific body composition metrics over the course of one season (pre- and post-season) among …

Enhancing Preparedness: A Genetic Study Of Sar-Cov-2 And Other Microbial Public Health Threats In Wastewater From A College Town, Christian N. Hutchinson

Master's Theses

Problem

The SARS-CoV-2 (COVID-19) pandemic revealed both the systemic vulnerabilities of our healthcare system as well as the importance of timely, localized data for informing public health responses. Traditional testing approaches were essential but often failed to capture the full extent of viral spread, especially in those with mild or asymptomatic conditions that relied on at home testing. This underreporting hindered effective allocation of resources and made developing effective intervention strategies difficult. We also realized the potential for wastewater surveillance to be applied to tracking antimicrobial resistance gene markers. Taken together, this approach should have important implications for improving public …

Anti-Ableist Teaching: Centering Disabled Perspectives In Collaborative Content-Creation, Suzanne Stolz, Toni Saia

Feminist Pedagogy

Although many service professionals (teachers, paraprofessionals, therapists, counselors) learn that disability inclusion is important, much of what they learn is still rooted in deficit terms. This paper describes why and how a collaboration of disabled scholars uses centering as a strategy in content development for an anti-ableist teaching resource website.

Mentoring In The Undergraduate Classroom And Beyond: Creating A Feminist Praxis, Satarupa Dasgupta

Feminist Pedagogy

In the following critical commentary, it is discussed how mentoring--- in the classroom and in academia---can be a feminist practice that comprises an essential part of being a feminist educator. Mentorship encompasses a process in which the mentor disseminates knowledge as well as psychosocial support that are perceived by the mentee as essential for professional or personal development (Sedlacek et al., 2007). Mentorship has been specifically found to fulfill professional needs for women, while enhancing their self-worth and sense of competence, and providing instances of role modeling and social affirmation (Meschitti & Lawton Smith, 2017).

Naming It Out Loud: Mid-Career Malaise, Katherine M. Johnson

Feminist Pedagogy

In this Critical Commentary, the author describes a sense of malaise during mid-career, due to increasing role demands as well as an uncertain educational and social environment. The purpose of this commentary is to offer an opportunity to express how these conditions affect one’s self-concept broadly but also as a feminist teacher. It is also to point out that this is not just a personal issue of 'failing' at one's work, but a broader, structural phenomenon.

De/Colonizing Education Research With Lessons From The Field, K. Kayon Morgan

Feminist Pedagogy

Academia is a reproductive site of settler colonialism (Mayorga et al., 2019) with practices and systems that exclude diverse identities. For universities to become more inclusive spaces, we must dismantle colonialist ideologies. One way is to consider alternative research approaches (Smith, 2021). This paper presents narratives from lessons in the field of research and teaching. The narrative encourages faculty and students to disrupt the status quo and normalize de/colonized research approaches in academia (Bhattacharya, 2021).

Measurements Of Spinal Posture During Common Strawberry Picking Positions Using Inertial Measurement Units, Madeline E. Everson

Master's Theses

Physically demanding professions, such as agriculture, put people at an increased

risk for experiencing back pain. This is due to the awkward and harmful postures sustained

throughout their workday. While studies have been done demonstrating that back pain is

prevalent amongst this community, most do not collect motion capture (MoCap) data,

leaving the specifics of the kinematics, such as the amount of time spent in harmful

postures, unknown. Unfortunately, MoCap data is typically limited to that of a lab or

facility where the cameras are housed. Therefore, this study aimed to mitigate the

inaccessibility of traditional MoCap by validating that …

Design-Build Capstone Projects: Continuing The Poly Canyon Legacy Of Learn-By-Doing, Anahid A. Behrouzi, Brayden A. Martinez, William R. Adam

Architectural Engineering

In the 1960s around ten acres of land behind the main campus of California Polytechnic State University in San Luis Obispo were set aside for students from the College of Architecture and Environmental Design to experiment with structural forms, materials, and construction methods. The publicly accessible Poly Canyon site has amassed a collection of structures: bridges crossing a seasonal creek, caretaker housing, a greenhouse, multiple sculptures and observation structures, among others. There were ebbs and flows of construction activity in Poly Canyon, often seeing a decade of activity with as much time dormant in between.

This paper focuses on the …

The Phoenix Takes Flight: The Importance Of Trauma-Informed Positive Education, Kathleen Turner Ledgerwood

Feminist Pedagogy

Since the pandemic, trauma has touched almost everyone. Pervasive illness, death, and isolation affected us in ways we have not paused to process. Many students were young and particularly affected by the pandemic. The rise in mental health concerns has made it more imperative to address mental health within our pedagogy. This article will outline strategies for helping to manage mental health within our pedagogy in order to better help everyone using an approach that aligns with trauma-informed and positive psychology pedagogical practices. Our future is one of compassionate, caring, trauma-informed work that bolsters the well-being of our students.

Exploring Dimensions Of Crystallized Identities, Candice L. Ruh

Feminist Pedagogy

For college students, learning about the components of identity can generate deeper knowledge about how personal and social identities differ, and how identities influence the way individuals experience socio-cultural systems and structures. The Exploring Dimensions of Crystallized Identities activity uses principles of self-reflexivity and dialogue to explore theoretical frameworks for practical application. This experiential activity is a facilitated dialogue driven by student involvement and is best suited for students in mid- to upper-level undergraduate courses. It encourages students to reflect on their and others’ identities, and to consider the social impacts of diversity in their lives.

Creating And Re-Energizing Communities Of Meaning Throughout A Course, Nancy A. Heise, Anum Ahmed

Feminist Pedagogy

We propose a feminist course approach wherein instructors build what Amie Macdonald (2002) called "communities of meaning" in their classrooms (p.120). Through an intentional focus on supporting students' 1) individual identities, 2) holistic well-being, and 3) epistemic "buy-in" to classroom content, students will connect more deeply not only to themselves and their classmates, but also to the course material. We suggest four community-building touchpoints as a starting point for instructors looking to integrate this course approach. We start with an activity to lessen awkwardness around first-day name pronunciation. We emphasize the importance of creating collaborative classroom expectations with students, and …

Evaluation Of Antibiotic Testing Protocols For Biofilm-Forming Escherichia Coli In A Microfluidic Platform, Caleb R. Telander

Master's Theses

Catheter-associated urinary tract infections remain an ongoing clinical problem due to biofilm persistence and antibiotic resistance. Standard antibiotic susceptibility testing cannot accurately reproduce flow conditions and the spatial complexity of the in vivoenvironment and is thus questionable in relevance to device-related infections. This study examines a microfluidic device designed to simulate physiologically relevant wall shear stress and antibiotic gradients in Escherichia coli biofilms. The polydimethylsiloxane-based system integrates a 16-well culture chamber with a gradient generator. Biofilm growth was observed using fluorescence microscopy of green fluorescent protein-labeled bacteria. Simulations performed using COMSOL Multiphysics software estimated the appropriate range of wall …

Effect Of Foot Strike Pattern On Joint Kinetics On A Downhill Slope, Evan Manley

Master's Theses

With recent increases in participation in outdoor running events, there is a need for research in downhill gait biomechanics. One change that could impact joint loading is foot strike pattern. Foot strike patterns have been categorized into rearfoot-strike (RFS), midfoot-strike (MFS), and forefoot-strike (FFS) [1]. While 75-99% of distance runners naturally RFS on level surfaces, they tend to move towards FFS when it is necessary to reduce vertical loading conditions at the knee [1]. The purpose of this study was to examine differences in peak vertical knee and ankle forces, knee moment, and ankle power, as well as cumulative force …
