Easy Prey, Annika L. Norris Jan 2023

Easy Prey, Annika L. Norris

Graduate Thesis and Dissertation 2023-2024

Easy Prey is a three-dimensional (3D) animated action comedy short film about stereotypes, expectations, and portrayals of strength that follows a ballerina as she is cornered in an alley. The fight that ensues expresses women's empowerment, physically and emotionally, by challenging preconceptions of ballerinas and the performance of femininity. This expression is founded on the intentional inclusion and exclusion of common cinematic tropes to efficiently convey key information while undermining common stereotypes. The action and atmosphere utilize classic film techniques to heighten and release tension. Easy Prey is inspired by my personal journey in healing my relationship with femininity and …

Impact On Infinite Asteroids: Analysis Of Ejecta Outcomes In Small Body Binary Systems, Jennifer Larson Jan 2023

Impact On Infinite Asteroids: Analysis Of Ejecta Outcomes In Small Body Binary Systems, Jennifer Larson

Electronic Theses and Dissertations, 2020-2023

Binary asteroid systems make up roughly 15% of objects occupying near-Earth space, the Main Belt, and trans-Neptunian space. The impact history of asteroids in binary systems represents an interesting aspect of the general problem pertaining to the nature and evolution of surfaces for such objects. Specifically, the post-impact dynamics of ejecta and its relation to surface modification is a challenging question owing, in part, to the unusual gravitational field in a binary system and the subsequent capture and emplacement of debris on either binary component. Observable differences or similarities between the two bodies in the color, reflectance, thermal properties, and …

To The Cosmos And Back: Modelling Ritualized Movement And Natural Sanctuaries Around The Manialtepec Lagoon, Sami Savateri Jan 2023

To The Cosmos And Back: Modelling Ritualized Movement And Natural Sanctuaries Around The Manialtepec Lagoon, Sami Savateri

Electronic Theses and Dissertations, 2020-2023

Depictions of movement in Late Postclassic and early Colonial Mesoamerican art, maps, and documents show a multi-faceted conception of movement as not only a means of physical travel through the landscape of the mundane world, but also a means to reach the cosmic realms of divine forces. In this thesis, I explored the intersection of movement and ritual in Late Postclassic Oaxaca by modelling a hypothetical ritual circuit around the Manialtepec Lagoon: a bioluminescent lagoon near Oaxaca's Pacific Coast that is significant in oral histories of the Indigenous Chatinos. The Manialtepec Basin lacks the level of continuous occupation or historic …

The Role Of Savoring In The Relationship Between Concussion History And Consummatory Reward, John O'Donnell Jan 2023

The Role Of Savoring In The Relationship Between Concussion History And Consummatory Reward, John O'Donnell

Electronic Theses and Dissertations, 2020-2023

Concussions are a relatively common neurological injury and are associated with several adverse outcomes including depression. Anhedonia is a core feature of depression, with multiple subtypes, including consummatory anhedonia (i.e., diminished reward liking). Reward liking is related conceptually to the practice of savoring pleasurable stimuli. Savoring has been a component of mindfulness-based interventions that have efficacy in treating depressive symptoms. The purpose of this study was to examine the relationships between lifetime concussion history, reward liking, savoring, and depression severity. 293 participants (56% women; mean age: 19.31) completed an online questionnaire and computer-based image savoring task. Contrary to expectations, no …

The Relationship Among Identity Development, Dark Personality, And Risk-Taking Behaviors, Reilly Branch Jan 2023

The Relationship Among Identity Development, Dark Personality, And Risk-Taking Behaviors, Reilly Branch

Electronic Theses and Dissertations, 2020-2023

Previous research has found significant relationships between various dark personality traits (Machiavellianism, sadism, narcissism, and psychopathy) and externalizing behaviors including delinquency (Muris et al., 2013). Although many studies have examined the relationships among dark personality, risk propensity, and delinquency, little research has examined the role of identity development and identity distress in predicting risky or antisocial behaviors. Therefore, this study examined the utility of using both the Dark Tetrad and identity dimensions to predict risk propensity and delinquent behaviors. Emerging adult college students (N = 424) completed an anonymous online survey battery. Results indicated that specific dark personality traits (i.e., …

Evolutionary History And Adaptation To Salinity In American Alligators, John Konvalina Jan 2023

Evolutionary History And Adaptation To Salinity In American Alligators, John Konvalina

Electronic Theses and Dissertations, 2020-2023

Stressful environments can commonly be found at the edge of a species range and may be a driver for adaption in suboptimal environments. Furthermore, the edge of a species' range can expand and contract over time, resulting in multiple independent invasions of the same stressful habitat. Elucidating population genetic structure and demographic history can aid in determining the which geologic factors impact range distributions and when climatic changes occurred driving genetic patterns observed in contemporary populations. Moreover, populations at the edge of the species range may adapt to the stressful environments that occur at the range edge and exhibit genetic …

It Is Time To Change The Way We Change, Thane Keller Jan 2023

It Is Time To Change The Way We Change, Thane Keller

Electronic Theses and Dissertations, 2020-2023

Seventy percent of organizational change initiatives fail. Among organizations where change and adaptation are necessary for survival, the U.S. military stands at the top. The disparity between desired health and fitness behaviors and actual behaviors is a glaring reminder that change is difficult to implement and that current change systems struggle. Merit-based systems offer a solution by rewarding and reinforcing good behavior to generate lasting change. This paper evaluates Kotter's Change Model and Nudge Theory and found them insufficient because they do not sufficiently address reinforcement learning or the temporal tie between behaviors and rewards for reinforcement. This paper then …

Capturing And Scaffolding The Complexities Of Self-Regulation During Game-Based Learning, Daryn Dever Jan 2023

Capturing And Scaffolding The Complexities Of Self-Regulation During Game-Based Learning, Daryn Dever

Electronic Theses and Dissertations, 2020-2023

Game-based learning environments (GBLEs) can offer students with engaging interactive instructional materials while also providing a research platform to investigate the dynamics and intricacies of effective self-regulated learning (SRL). Past research has indicated learners are often unable to monitor and regulate their cognitive and metacognitive processes within GBLEs accurately and effectively on their own due mostly to the open-ended nature of these environments. The future design and development of GBLEs and embedded scaffolds, therefore, require a better understanding of the discrepancies between the affordances of GBLEs and the required use of SRL. Specifically, how to incorporate interdisciplinary theories and concepts …

Gendered And Racialized Bodies In Dobbs V. Jackson Women's Health Organization, Saphronia Carson Jan 2023

Gendered And Racialized Bodies In Dobbs V. Jackson Women's Health Organization, Saphronia Carson

Electronic Theses and Dissertations, 2020-2023

In June 2022 the US Supreme Court overturned Roe v. Wade, abandoning nearly 50 years of precedent, and removing federal protections for abortion access. In doing so, the Court drew on a lineage of explicit and implicit discourses that have constructed abortions, abortion providers, and pregnant and fetal bodies in ways that make overturning Roe seem inevitable. This thesis takes a reproductive justice perspective while conducting a feminist critical discourse analysis of the majority and concurring opinions in Dobbs. Two main findings stand out. First, the decision relies on originalist constructions of abortions, abortion providers, pregnant people, and fetuses to …

Sexual Violence In Armed Conflict: How Levels Of Sexual Violence In Peacetime Affect Levels Of Sexual Violence In Conflict, Sydney Snowden Jan 2023

Sexual Violence In Armed Conflict: How Levels Of Sexual Violence In Peacetime Affect Levels Of Sexual Violence In Conflict, Sydney Snowden

Electronic Theses and Dissertations, 2020-2023

Why do some armed conflicts have higher levels of sexual violence than others? Some existing theoretical work has pointed toward the possibility that the presence of sexual violence before armed conflict occurs can impact the levels of sexual violence during armed conflict, however, little empirical work has examined these theories. This thesis uses new, unique data to address concerns about the validity of previous studies and to explore sexual violence over the boundaries of time, looking at pre-conflict levels of sexual violence in addition to levels of sexual violence during armed conflicts. Using a parallel mixed methods research design, this …

The Assemblage Of The Rings: Reading Lord Of The Rings Through The Philosophy Of Gilles Deleuze And Félix Guattari, Kieran Leeds Jan 2023

The Assemblage Of The Rings: Reading Lord Of The Rings Through The Philosophy Of Gilles Deleuze And Félix Guattari, Kieran Leeds

Electronic Theses and Dissertations, 2020-2023

J.R.R. Tolkien's Lord of the Rings is a monument to literary achievement; a world built so completely that other literature, both canonical and not, attempts in vain to match its grandeur. Likewise, Gilles Deleuze and Félix Guattari's body of philosophy is conspicuous not only for its thematic variation across books but also the profundity of its concepts. Given this, it is shocking then that the critical apparatuses of Deleuze and Guattari have not been used to explore Tolkien's novels, given the innate symmetry between the two bodies of work. While ample research has been carried out regarding each separately, there …

Analysis Of Polycyclic Aromatic Hydrocarbons In Tobacco Related Samples Via High Performance Liquid Chromatography And Laser Excited Time Resolved Shpol' Skii Spectroscopy, Ahmed Comas

Electronic Theses and Dissertations, 2020-2023

Human exposure to polycyclic aromatic hydrocarbons (PAHs) due to cigarette smoke is well known. It is also known that PAHs are not inherent components of tobacco. Their presence in cigarette smoke results from the curing process of tobacco leaves used for the fabrication of cigarettes and the incomplete combustion of tobacco during the smoking process. The two chromatographic versions of EPA method 610 are popular approaches for the analysis of PAHs in a wide variety of samples. This method, which is based either on High-Performance Liquid-Chromatography (HPLC) or Gas-Chromatography (GC) has shown the presence of Benzo[a]pyrene (B[a]P) in tobacco samples …
