Furthermore, ~40% of the...

Seeing Gender Everywhere: Assessing the Impact of Traditional Gender Attitudes on American and European Public Opinion

Olyvia Rebeccah Christley
This dissertation examines the role that deeply held beliefs about gender roles, masculinity, and femininity—otherwise known as gender attitudes—have on public opinion. Gender’s influence stretches far beyond the role of individual gender identities and gender consciousness to encompass the ways in which feelings or beliefs about masculinity and femininity (either conscious or subconscious) shape behavior and opinions on a variety of issues—many of which may have no explicit connection to gender. Despite the prominent role...

Poetry for Identity: A Phenomenological Pedagogy of Poetry to Support Students' Self-Concept Clarity

Janice Murray
Secondary students often struggle to see value in studying poetry. Because they are at a developmental stage that involves identity development, one useful approach to teaching poetry is connecting it to identity development through the idea of self-concept clarity. Self-concept clarity is the extent to which someone has a clear, confident, and consistent sense of who they are (Campbell, et al. 141). Not only does self-concept clarity align with secondary students’ developmental stage, it is...

Engineering a Resilient Healthcare System: Using Heart Attack Outcomes and Treatment Methods in Pennsylvania; Fast and Fit: Efforts to Promote Healthier Food Options in U.S. Restaurant Chains

Emily Pham
Due to significant gaps in current healthcare delivery models, patients have to receive non-emergent or routine care at other facilities. When fluctuating factors or unprecedented circumstances like a pandemic occur, the healthcare system is further strained and bottlenecks follow from this fixed facility model, leading to basic needs unfulfilled. The current healthcare delivery system therefore is rigid and not adaptable, unable to accommodate fluctuating variables and various scenarios. As a result, the purpose of the...
