Freedom, Abortion, And Hypocrisy: The Effect Of Hypocrisy On Pro-Life Abortion Attitudes, Emily M. Vance

Graduate Theses and Dissertations

Previous research suggests that highlighting the gap between inconsistent values can result in long-term attitude change (Rokeach, 1971), that feeling hypocritical might prompt pro-attitudinal behavior (e.g., Dickerson et al., 1992), and that a reactance decoy makes participants more receptive to subsequent persuasive messages (Schumpe et al., 2020). Drawing from these findings, the purpose of the present study was to investigate whether the impact of induced hypocrisy on pro-life abortion attitudes, an attitude commonly grounded in the value of freedom, depended on a reactance decoy. Consistent with Aronson et al.’s paradigm (1991), participants first publicly advocated for the importance of personal …

A Narrative Research Study On How Brazilian Women Executives Build A Sense Of Community And Belonging When Transferred To The United States, Silvia Regina Siqueira

Graduate Theses and Dissertations

According to the American Immigration Council (2021), 14 percent of the United States population is foreign-born. Immigrants have enriched American culture and enhanced our influence in the world. People feel a need to belong and have an inherent desire for deep, lasting, and meaningful connections (Baumeister & Leary, 1995). Research suggests that humans are fundamentally and pervasively motivated by a need to belong and the desire to form and maintain enduring interpersonal attachments (Allen, Kern, Rozek, McInerney & George, 2021). These authors also define immigrants’ sense of belonging in terms of how they make sense of their social identification with …

Mitral Valve Imaging And Biomechanics: A Workflow Towards Computational Modeling And Validation, Sam Stephens

Graduate Theses and Dissertations

The mitral valve serves a critical role in healthy cardiac function by ensuring the unidirectional flow of oxygenated blood from the left atrium into the left ventricle. It experiences the highest pressures found within the heart and its closure is the result of a complex interaction of several different structures that, furthermore, are unique to each individual. Despite the valve’s vital role however, the specific function of these constituent structures is not fully understood. This, confounded by its asymmetric, personalized nature, make surgical interventions for the mitral valve far less effective than for its neighboring aortic valve. Efforts to overcome …

The Relationship Between Upper Body Muscular Power And Objectively Measured Physical Function In Healthy Older Adults, Jordan Stroope

Graduate Theses and Dissertations

The population of older adults is growing rapidly worldwide. There are significant challenges associated with an aging population, many of which are related to declining physical function. Muscular power has previously been postulated as an important physical characteristic for preserving physical function, however, much of the research has measured lower body muscular power against functional outcomes. The importance of upper body muscular power (UBMP) for physical function outcomes is less clear, thus, this study sought to examine that relationship. Forty-two older adults between the ages of 50 – 70 (avg = 60.5 years  5.7) were recruited for the current …

Ecological, Evolutionary, And Temporal Dynamics Of Animal Mortality Events, Simon Patrick Tye

Graduate Theses and Dissertations

Global declines of animal abundances are emblematic of the Anthropocene. Recent animal declines have increasingly involved more frequent and intense die-offs within populations, or mass mortality events (MMEs). These extreme demographic events can lead to rapid changes in biological communities, either by imperiling the affected population or influencing populations remaining within communities. To date, there is still limited information about the effects of predator MMEs on immediate ecological dynamics within communities and rapid evolutionary dynamics within remaining populations that may ensue. Moreover, few approaches exist to predict future occurrences of predator MMEs across broad spatial scales. To address these gaps, …
