The Development Of Sexual Health Educational Canvas Modules For Cal Poly Students, Alexa J. Asson, Dillan Chiewpanich, Amanda Hodges, Tanya Patil

Biological Sciences

Purpose: Sexual health education continues to be a taboo topic underrepresented in young adult health education. Many high school students do not receive the sexual health education they need. One study found that 34% of girls and 42% of boys left high school without education on birth control methods (Wong et al., 2019). Furthermore, students entering college have varying, often inadequate, levels of sexual health knowledge. After examining sexual health data at California Polytechnic State University (Cal Poly), the Cal Poly Sexual and Reproductive Health (SRH) Lab found that students engage in risky sexual behaviors. For example, nearly one quarter …

Advising Communication In Finance, Jordan J. Schumann

Communication Studies

Communication is an important factor in relationships. When it comes to financial advising and the advisors’ relationship with their clients, it is no different. However, the driving factor of what makes a client choose one advisor over another remains in question. As such a question builds: what does an advisor do to maintain a client and promote gaining new ones? This study examines the experiences current advisors have had in their respective careers. To examine this topic, communication theories (Social Cognitive Theory, Source Credibility Theory, and Uncertainty Reduction Theory) are called upon to inform the outcomes of advisors' experiences. The …

Benefits Of Having A Disability Cultural Center At Cal Poly, Chau Nguyen

Political Science

All colleges and universities in the United States are legally required to accommodate their students with disabilities. However, many schools do not support their disabled student body in ways that go beyond what they are legally required to provide under the Americans with Disabilities Act (ADA) and Section 504 of the Rehabilitation Act. Though every university and college in the United States has a dedicated ADA compliance office, students with disabilities still express that their holistic needs are unmet and that they feel unsupported by their schools. Establishing Disability Cultural Programs and Centers is one method that colleges and universities …

Adaptive Fascism: A Study Of Far-Right Politics In The Americas, Blake Mustachio

Master's Theses

Populism as a term is too ambiguous to describe the surge in far-right nationalistic leaders both during the Cold War and the present day. This paper proposes to solve this quagmire by proposing the term adaptive fascism. Adaptive fascism is the idea that far- right leaders using tactics that have legacies within fascist rhetoric have adapted the fascist rhetoric to fit more within the geopolitical situations of each leader’s respective time period. Looking at both leaders of the Cold War, including Jorge Videla of Argentina and Augusto Pinochet of Chile. As well as modern day leaders, Donald Trump of the …

Suppression Of National Identities: Ukrainian And Baltic Cultures In The Soviet Union, Jonathan H. Mastman

Master's Theses

This thesis defines the formation and consummation of Soviet Bolshevism as another imperialist force rather than its stated objective of freeing the people of the United Soviet Socialist Republics from the clutches of an inequitable elite. Through the policies and objectives of the Soviet government the workers and citizens of Ukraine and the Baltic republics were not liberated or given autonomy over their lives and labor, as Marxist-Leninism would have them believe. I review the Russification efforts found first in the Tsarist Russian Empire and then continued by Soviets in the nature of pursuing or denying cultural, political, and economic …

Development Of Wiskott-Aldrich Syndrome Knock Out Protocol For Drug Substance Assay Development, Julia C. Hanna

Master's Theses

Wiskott-Aldrich Syndrome (WAS) is a rare X-linked primary immunodeficiency affecting approximately 1 in 100,000 live XY births in North America and is caused by a mutation to the WAS gene which is expressed across hematopoietic lineages. The WAS protein (WASp) plays a role in regulating actin polymerization. On a cellular level, there are a variety of effects of a lack of WASp or expression of a dysfunctional WASp protein for patients including issues with migration, adhesion, chemotactic response, phagocytosis, activation, and proliferation across different cell types in addition to reduced platelet size and output. This can lead to several systematic …

Examining The Use Of A Network Bypass To Circumvent Data Diodes Within Industrial Control Systems, Bryce Molesh

Charting Their Own Course: Individualized Contract Grading As A Practice Of Freedom, Sarah Stone Watt

Feminist Pedagogy

Students move through college along different curricular and personal pathways. Feminist scholars have explored multiple ways of inviting students to bring their diverse experiences into the classroom. However, it can be challenging to invite diversity while requiring each student to navigate a standardized curriculum. I propose unilateral grading contracts as one tool to enable students to move through a course while leveraging their strengths, helping them grow, and sharing their experiences to enrich the broader class community and achieve the course learning outcomes.

Digital Waves: Communicating Feminist Movements, Shauna M. Macdonald

Feminist Pedagogy

Online learning provides opportunities for pedagogical growth and innovation. When tasked with teaching an undergraduate Gender and Communication class during a virtual semester (amid the COVID-19 pandemic), I sought ways to engage students through online technologies rather than working against or despite them. The Digital Waves (DW) assignment, one that asks students to research and then create digital representations of a particular “wave” of feminism, was one of several strategies I adopted; it quickly evolved into a favorite.

“Civil Dialogue” As Feminist Pedagogy: Engendering Material And Symbolic Movement, Sarah E. Jones

Feminist Pedagogy

In the United States, we are socialized to think in Western dualisms, and these patterns of communication characterize discussion of social issues. Consequently, discussion becomes debate and dominant approaches to inquiry are privileged over experience with persuasion being the end goal. Fostering agency, cultivating empathetic understanding, and facilitating critical thought are made more difficult—outcomes that are neither productive nor edifying in the college classroom. This original teaching activity resists hierarchical forms of debate in favor of visibility and solidarity in discussions of gendered violence. Grounded in principles of invitational rhetoric and provocation, the activity uses a “Civil Dialogue” format to …

Moving Students Toward Activism: Microblogging About Gender-Based Violence To Channel Emotion And Encourage Action, Janell C. Bauer

Feminist Pedagogy

For students in gender studies courses, a unit on gender-based violence can be jarring. However, faculty can reflect on how to help students engage their emotions to enhance their learning and participate in gender activism. Students also benefit through the opportunity to reflect on their feelings and engage their emotional experience as part of their learning. In this assignment, I share how I’ve used a microblogging assignment to channel students’ emotions about gender-based violence into action-oriented digital activism content.

Implementation Of Methods For Cell Therapy Research And Assessment Of The Impact Of Cryopreservation, Samantha Lynes

Master's Theses

Cell therapy is the administration of living cells into a patient to prevent or treat a variety of diseases and illnesses. The cell therapy industry is rapidly expanding, and continued research is necessary for manufacturing safe and effective therapies. Although cell therapy manufacturing generally involves cryopreservation processes for storage, there are limited standards for cryopreservation processes and assays required to evaluate cell therapies post-thaw, and limited understanding exists about how a recovery period post-thaw could impact cell health. The overall goal of this thesis was to evaluate the effect of cryopreservation and potential subsequent recovery time on cell viability.
