Regulation And Localization Of Urease In Sporosarcina Pasteurii: Implications For Coastal Protection, Amar Kosovac

UNF Graduate Theses and Dissertations

Coastal erosion is a persistent problem exacerbated by global warming. As the climate changes, the southeastern coast is likely to experience an increased frequency and intensity of storms, which can significantly damage the coastline. The coast is crucial as it serves as a habitat for numerous animals, supports tourism, and underpins infrastructure. Microbially induced calcite precipitation (MICP) is a novel method to enhance erosion resistance in sandy soils using the non-pathogenic bacterium Sporosarcina pasteurii. S. pasteurii produces urease to catalyze urea into bicarbonate, which drives the precipitation of calcium carbonate. Maximal expression of urease is a limiting factor for …

Mass Homicides And Mass Shootings: Comparisons, Trends, And Unpacking Further, Stefana E. Lotempio

Electronic Theses & Dissertations (2024 - present)

Mass shootings have garnered more public attention in recent years, in large part due to their increase in both frequency and lethality. Despite public concern, policy and prevention efforts have remained limited and have not yet resulted in a decrease in these events. Understanding mass shootings as a subset of mass murder will help identify how mass shootings are unique from other mass murders, which will help to identify more effective prevention tactics. Additionally, exploring mass shooting trends in the context of homicide trends and other crime trends will illuminate patterns that can be used to inform policy and prevention …

Studies Towards Chemical Synthesis Of Homogeneous Prion Glycoprotein, Baotong Tian

Electronic Theses & Dissertations (2024 - present)

Prion diseases are fatal neurodegenerative disorders initiated by conformational misfolding of the prion protein (PrP), which generates pathogenic conformers that propagate via templated conversion and accumulate as aggregates. Glycosylation can modulate the PrP folding energy landscape, thereby biasing folding trajectories and the distribution of resulting conformational states. Bank vole PrP contains two N-linked glycosylation sites, and disentangling the contributions of site occupancy versus glycan structure requires homogeneous, site-defined glycoforms. In contrast, biosynthetic expression typically produces heterogeneous glycoform ensembles due to multistep Golgi processing, precluding independent control of glycan identity at each site. Here we report a chemical synthesis strategy of …

Constructing The Political “Other”: Affective Polarization And Cross-Ideological Portrayals On Instagram, Amanda M. Novellin

Electronic Theses & Dissertations (2024 - present)

Instagram has frequently been characterized by users as a platform that permits the circulation of hostile and adversarial political content due to comparatively limited moderation practices. In January 2025, Meta CEO Mark Zuckerberg announced changes to content moderation policies on Facebook and Instagram, including the removal of third-party fact-checking mechanisms. These platform-level changes further reshaped the political information environment in which online discourse occurs. However, even prior to these policy changes, Instagram had established itself as a prominent space for highly polarized political expression across the ideological spectrum.

This thesis examines how political polarization in the United States is reflected …

Wherefore Art Thou Competitors? How Situational Affordances Help Differentiate Among Prosocials, Individualists, And Competitors, Y. Liu, A.W. Stivers, R.O. Murphy, N.J. Van Doesum, J. Joireman, M. Gallucci, E. Aharonov-Majar, U. Athenstaedt, L. Bai, R. Böhm, N.R. Buchan, X.-P. Chen, K.B. Dumont, J.B. Engelmann, Li, Norman P., H. Euh, S. Fiedler, J. Friesen, S. Gächter, C. Garcia

Research Collection School of Social Sciences

The Triple Dominance Measure (choosing between prosocial, individualistic, and competitive options) and the Slider Measure (“sliding” between various orientations, for example, from individualistic to prosocial) are two widely used techniques to measure social value orientation, that is, the weight individuals assign to own and others’ outcomes in interdependent situations. Surprisingly, there is only moderate correspondence between these measures, but it is unclear why and what the implications are for identifying individual differences in social value orientation. Using a dataset of 8021 participants from 31 countries and regions, this study revealed that the Slider Measure identified fewer competitors than the Triple …

Great Power Competition In Africa: Sustaining Openness Amidst Transnational Threats And Authoritarian Fragmentation, Chick Edmond

Political Science & Geography Faculty Publications

As the United States seeks to position itself in an increasingly competitive world, Africa has emerged as an increasingly key arena of great power competition where the United States, China, and Russia are competing to determine the nature of political norms, economic governance and security architecture on the continent.

The combination of growing transnational threats (such as terrorism, pandemics, climate-related instability, and digital vulnerability), and growing authoritarianism, has transformed the continent into a testbed for competing visions of international order. In light of this backdrop, this paper posits that the United States must pursue a strategy of sustained strategic openness …

The Evolving Beijing Consensus: Chinese Communist Party Political Control And Economic Trade Offs, Ian Murphy

Political Science & Geography Faculty Publications

China’s rapid economic rise and unique development trajectory have long been the subject of scholarly debate, often framed through the concept of the “Beijing Consensus” as an alternative to the Washington Consensus. While initial conceptualizations highlight innovation, sustainability, and national sovereignty, later analyses highlighted elements like state capitalism and authoritarianism, particularly in the wake of the 2008 Global Financial Crisis. This paper argues that the Beijing Consensus is undergoing a significant evolution under Chairman Xi Jinping, increasingly prioritizing the Chinese Communist Party’s political security, regime stability, and ideological control at the expense of economic growth. This marks a notable departure …

Comparing Consent Culture: Are Kinky People More Concerned About Consent?, Hannah Tarleton

Graduate Research Theses & Dissertations

The BDSM community has become an increasingly popular subject of study in relation to consent culture; however, the bulk of this research has been qualitative and lacks comparison to non-BDSM practitioners. The theory of planned behavior was used to design a measure comparing consent culture across 668 BDSM practitioners and non-practitioners. As predicted, the relationships specified by theory of planned behavior was replicated for both BDSM practitioners and nonpractitioners. Contrary to predictions, no significant differences were found between BDSM practitioners and non-practitioners for norms or behavioral intentions; however, BDSM practitioners reported significantly higher perceived behavioral control. Within the BDSM community, …

This thesis examines the younger generation or youth perceptions of China’s economic soft power. This qualitative research uses the case study of Cambodia as small state and …

How Autistic Children Define Novel And Real Words, Henry James Tomiser

Graduate Research Theses & Dissertations

Word knowledge is highly valuable to Autistic individuals, and although much research has characterized Autistic children’s vocabulary breadth (i.e., the number of lexical entries), less attention has been paid to vocabulary depth (i.e., the richness with which one understands a given word). In this exploratory post-hoc study, 11 Autistic children (one assigned female at birth) participated in novel and real word learning paradigms in which child-friendly referents were paired with CVCV word forms. Participants were then asked to provide open-ended definitions of the words. Definitions were parsed into meaningful subunits, or semantic features. Semantic features were coded by type of …

Influence Of Parental Immigration On Children Of Latino Immigrants’ Attachment And Substance Use, Leilanis Cancel-Lopez

Graduate Research Theses & Dissertations

This study aimed to explore how children of Latino immigrants described their attachment and substance use experiences. The narrative that formed implies that throughout their adolescence, children of Latino immigrants use substances in part to cope with their parents’ heightened expectations for the participants to perform well in school/work/life. Additional results find that children of Latino immigrants also form a sense of exoneration for their parents upon reaching young adulthood. Clinical implications include the use of a systemic perspective when approaching children of immigrants when treating substance use and the inclusion of this narrative when creating prevention strategies for immigrant …

Hot Topic Of The Cold War: Analyzing The Bomb In American Media During The Late Twentieth Century, Ryan Lambert

Graduate Research Theses & Dissertations

This thesis explores nuclear war–related media (i.e., media involving “the Bomb”) from the late twentieth century, beginning in the early 1950s and ending in the late 1990s, although media from the 2000s and beyond are briefly touched on. Unlike other studies of nuclear war narratives, this analysis intends to explore this media through a rhetorical framework of an “eroding” society, and the “erosion” concepts of the 50s–70s paved the way for cumulative “erosion” storylines in the 80s (the height of the Cold War), and then “restoration” storylines in the 90s (after the end of the Cold War). This framework is …

Trust Is Difficult To Gain, Yet Easily Broken: The Impact Of Negative Police Encounters On Police–Community Relations, Brooke J. Pirozek

Honors College Theses

Trust between law enforcement agencies and their respective communities is arguably one of the most contentious issues within contemporary criminal justice research in the United States. This is because, despite the fact that law enforcement institutions rely significantly on the public's assistance and cooperation in fighting crime and enforcing social order, there still exist negative relations between law enforcement and their communities, mainly attributed to feelings of unfair treatment, abuse of power, and a lack of accountability. This study seeks to understand the role of negative police encounters in shaping community trust and perceptions of police legitimacy, with a special …
