The Impact Of Virtual Backgrounds In Video-Mediated Selection And The Role Of Candidate Qualifications, Mira Gruber

Graduate Thesis and Dissertation post-2024

Videoconferencing allows users to manage their self-presentation through virtual backgrounds that mask their immediate physical environment. Prior research suggests that backgrounds depicting professional home spaces (e.g., bookshelves) elicit more favorable impressions than those that depict personal home spaces (e.g., bedrooms). Expectancy Violations Theory (EVT) provides a framework for understanding such effects. The present dissertation applied EVT to video-mediated selection interviews, that have become increasingly popular since the COVID-19 pandemic. Given the strict expectations for professionalism in interviews, virtual backgrounds that deviate from such expectations may negatively impact hiring decisions. Consequently, this work examined the impact of two virtual background types, …

Requisites For A Dream: An Evaluation Into The National Urban League’S Adjustment Efforts For Southern Migrants, 1911-1930, Adaeze Nwigwe

Graduate Thesis and Dissertation post-2024

The American Dream is loosely defined as a universalist rhetoric that promises any American the opportunity to succeed in life. However, for African Americans this has not always been guaranteed. Historiography around the mantra uncovers a gap in consideration for Black Americans’ unique marginalization in American society despite their long history within the nation. This paradox inspired a myriad of proposed solutions towards racial disparities, with the early twentieth century favoring ideas of racial uplift as a panacea for prejudice. This thesis examines the use of racial uplift as a solution by the National Urban League during the first half …

Macabre Therapeutics: An Exploration Into The Cathartic Nature Of Splatter Utilizing The Saw Franchise As Corpus, Rosalind E. Rohrbaugh

Under Control, Eric Tegethoff

Graduate Thesis and Dissertation post-2024

Under Control is a collection of six short stories focused on masculinity. The stories explore family, climate change, nationalism, and the nature of work. “A Survey of Man” and “Snake Pit” dive into the corrosive effects of capitalism on men in society. In “The Art of War,” the narrator finds the cost of pursuing healing outside of society’s prescribed norms. Society’s norms also act on the characters in “My Country, My Cybertruck” and “Bad Reporting.” The collection ends with “Virtual Idaho,” a short story that scrutinizes the masculine barriers to properly grieving for a loved one.

Small Ripple, Big Waves: Individual Political Attitudes, Populism, Illiberalism And Democratic Resilience, Paulo Ricardo Valle

Graduate Thesis and Dissertation post-2024

Why do individuals who support democracy also endorse populist and illiberal attitudes? Current literature focuses efforts on exploring the role that institutions and political actors have in democracy resilience (Levitsky & Ziblatt, 2019; Merkel & Lührmann, 2021). However, relatively few academic works have examined this phenomenon at the individual level. With the aim to exploring the causal effect between individual political attitudes, anti-democratic threats, and democratic resilience at the individual level, this study applies a micro-level theoretical approach to assess how individuals’ political attitudes toward populism and illiberalism affect their support for democratic values. To test the hypotheses, this study …

ADL is applied specifically to the influenced …

Optomechanical Interactions And Dynamics In Nanoparticle Systems, Sohila Abdelhafiz

Graduate Thesis and Dissertation post-2024

This dissertation investigates the coupling between optical forces and the dynamics of nanoparticle systems. Using theoretical models, simulations and experiments, we explore how light mediates interactions between nanoparticles leading to optical binding, nonreciprocal forces, and collective behavior in colloidal suspensions.

We first examine the dynamics and interactions of particles under illumination due to complex electromagnetic forces. Of particular interest are interparticle forces between particles with specific optical properties such as those satisfying the Kerker scattering conditions. We demonstrate the wavelength-dependent dynamics of such Kerker dimers and establish conditions required for their stable longitudinal binding. We also describe a one-way non-reciprocal …

Examination Of Driving Experience, Hazard Perception & Distracted Driving: Going Beyond Individual Factors By Using A Social-Ecological Framework, Alejandro A. Arca

Graduate Thesis and Dissertation post-2024

This research included two studies that examined the roles of nomophobia, driving experience, distraction presence, and hazard presence on driving behavior. In Study 1, a hazard perception task was used to assess participants’ hazard perception accuracy rate and reaction time. Results showed that novice drivers displayed significantly higher levels of nomophobia and lower self-efficacy scores, divided attention, and working memory scores compared to their experienced counterparts. Furthermore, the results also showed that novice drivers reported faster reaction times to hazards, which may be associated with poor impulse control as previously reported in the literature. Study 2 was conducted to further …
