Approximating The Maximum Weighted Independent Set Problem Empirically, Sue Sue

College of Engineering Summer Undergraduate Research Program

In this project we investigate approximation algorithms for the maximum weighted independent set (MWIS) problem in random graphs that approximate real-world graphs, such as social networks. The problem involves finding a large collection of nodes in a network (vertices in a graph) such that no two nodes are directly connected to one another. Applications of the MWIS problem are broad and include clique-finding algorithms as well as the use of large independent sets in distributed algorithms. We build on prior work by the mentor with a SURP 2024 and senior project, in which preliminary findings suggested that a standard greedy …

Using Classroom Response Systems For Feminist Pedagogy In Large Classes, Sarah Rainey-Smithback, Nicole Kalaf-Hughes

Feminist Pedagogy

Most practitioners using feminist pedagogy assert small, discussion-based classrooms are best suited for creating power-sharing spaces where students are co-creators of knowledge. While we do not disagree that small classes are well-matched for feminist pedagogy, we challenge the assumption that feminist pedagogy cannot be practiced in large classes. This article explores how Top Hat, a web-enabled classroom response system (CRS), can be used to facilitate feminist pedagogy in a large Introduction to Women’s Studies class. Using data on student perceptions of the CRS, as well as instructor reflections on a technology-centered feminist classroom, this work suggests CRS can be used …

A Drop In The Ocean: A Critical Look At Belonging And Community In Carceral Setting, Jelena Petrovic, Jacob Bickel, Jonathan Cantero, Romano Estrada, Malcolm J. Thrower, Gregory White

Feminist Pedagogy

In this commentary, we explore the opportunities and challenges of community building within our own higher education in prison program. Since 2015, the program fostered a community grounded in feminist pedagogy, emphasizing interconnectedness and decentralization of power. However, our 2024 evaluation revealed that new students often feel excluded and marginalized, highlighting the aspirational nature of the community. With this in mind, we examine how incarcerated individuals become members of a learning community and the unique struggles they face. We also discuss the importance of creating classroom communities that support students' sense of belonging, particularly in carceral settings, while also reflecting …

Beyond Deep Listening With The ‘Feminist Ear’: Introducing The Full-Circle Model Of Listening And Expressing, Alana M. Nicastro, Shelly Valdez

Feminist Pedagogy

Feminist pedagogy calls for more than presence and voice—it asks us to listen deeply and express courageously. This article introduces the Full-Circle Model of Listening and Expressing, a framework that extends the concept of deep listening by pairing it with intentional expression. Building on previous work on deep listening (Nicastro & Valdez, 2022), we articulate six essential components of feminist communication: openness, attunement, integration (for listening), and self-reflection, courage, and intentional dialogue (for expressing). These interconnected practices foster genuine connection, challenge hierarchies, and make visible the often-unseen emotional labor of communication. Using the metaphor of a circle, we explore how …

Teaching #Metoo And #Blacklivesmatter Amid The Anti-Woke Moral Panic, Stephanie Medden

Feminist Pedagogy

The introduction of over 100 anti-DEI bills across 30 states and President Trump’s signing of executive orders that target DEI programs demonstrate the backlash against the social, cultural, and political gains made by movements such as #MeToo and #BlackLivesMatter. “Anti-woke" sentiment presents challenges for educators preparing students to engage critically with certain histories, movements, and theories. This article explains current debates around what it means to be “woke”; provides strategies to teach about inequality across race, gender, class, and sexuality in this polarized environment; and imagines futures that uphold the ideals of diversity, equity, and inclusion.

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.

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 …

Acoustic And Hemodynamic Analysis Of Phantoms: Roughness And Flow Dynamics, Ethan Erik Olof Sundberg

Master's Theses

The purpose of this study was to determine whether different vascular phantoms, with and without a surrogate arm, could serve as effective analogs to the human brachial artery for assessing endothelial dysfunction, an early indicator of cardiovascular disease, particularly atherosclerosis. Atherosclerosis is characterized by plaque buildup and endothelial damage, which precede more severe clinical events and are often detectable through changes in vascular function. A 40” water tower was used to simulate diastolic pressure, enabling water flow through each phantom. Strain gauge pressure transducers were placed at both ends of the phantoms to measure pressure drop, while a microphone captured …

Optimizing Microfluidic Murine Fibroblast And Human Epidermal Keratinocyte Cell Culture In 70Μm Microwells, Christian Navarro

Master's Theses

Cell culture is an essential technique utilized in biotechnology and medicine to remove systemic influences to study cellular behavior and morphological development of individual cell lines. However, conventional cell culture is two-dimensional and static meaning it can’t easily mimic in vivo conditions such as multicellular cell to cell interactions, fluid perfusion, or 3D structures which might alter cellular behavior and morphology. Microfluidic cell culture allows for the incorporation of in vivo conditions such as perfusion and chemical gradients allowing for more physiologically accurate models. The goal of this study is to develop a protocol for testing a microfluidic chip designed …
