The Peaceful Transition Of Spain: How Authoritarianism Became Democracy, Emma Haiser

Honors Theses

The peaceful transition from authoritarianism under Francisco Franco to a democratic constitutional monarchy after Franco’s death stands as a critical juncture in modern Spanish history because of the uniqueness of the historical event. The transition occurred without direct foreign intervention to manipulate Spanish politicians into passing democratic legislation; instead, the transition was initiated by Francoist leaders who willingly enacted the regime’s change which undermined their initial place in society. The Spanish transition was caused by three main factors: societal opposition to the Francoist regime, democratic international influence, and progressive leaders taking office after Franco’s death. This paper will explore the …

Food Insecurity On Wmu’S Campus: Student Satisfaction Of The Invisible Need Project, Ava Daly

Honors Theses

Previous research suggests that food insecurity is higher among college students and individuals from minority populations than the general population. Many college campuses have recognized this issue and developed on-campus food pantries to mitigate food insecurity among students. Nevertheless, barriers exist that prevent students from utilizing on-campus pantries. The purpose of this study was to investigate college students’ relationship to food and food access at Western Michigan University (WMU). Student satisfaction of WMU’s on-campus food pantry, The Invisible Need Project, was also explored. Data were gathered through a 28-question online survey and one in-person focus group. Participants were undergraduate and …

Inclusion Of Kinetic Proteomics In Multi-Omics Methods To Analyze Calorie Restriction Effects On Aging, Richard Hajime Carson

Theses and Dissertations

One of the greatest risk factors for disease is advanced age. As the human lifespan has increased, so too have the burdens of caring for an increasingly older population suffering from rising rates of cardiovascular disease, kidney disease, diabetes, and dementia. The need for improving medical technology and developing new therapies for age-related diseases is manifest. Yet our understanding of the processes of aging and how to attenuate the effects of aging remains incomplete. Various studies have established calorie restriction as a robust method for extending lifespan in laboratory organisms; however the mechanism is a topic of much debate. Advancing …
