Post-Crisis Organizational Learning Thresholds, Pitfalls And The Risk Of Repeated Crises: Clarifying The Discourse Of Renewal Theory, Rodrigo Soares

Electronic Theses and Dissertations, 2020-2023

Through a case study analysis of repeated crises that impacted the same organization in Brazil, this dissertation aimed to solve an applied problem: the potential for unresolved or amplified risk for organizations and their stakeholders facing repeated crises due to incomplete post-crisis learning. This research expands and clarifies the understanding of organizational learning, particularly in the Discourse of Renewal theory, by exploring the potential for organizations to ascertain vital lessons for a crisis but fail to communicatively constitute them as central features of a renewed organization. The study investigated an organization's failure to avoid repeating a crisis within a relatively …

Attenuation Of Excess Tnfα Release In Crohn's Disease By Silencing Of Irhoms 1/2 And The Restoration Of Tgfβ-Mediated Immunosuppression Through The Modulation Of Tace Trafficking, Taylor Louis

Electronic Theses and Dissertations, 2020-2023

Although treatment of Crohn's disease (CD) with TNFa monoclonal antibodies is beneficial, many patients stop responding over time and become at risk of acquiring infections. This study investigated an alternative approach to attenuate the release of excess TNFα by silencing iRHOMs 1/2 with the intention of restoring TGFβ-mediated Immunosuppression through Mitigation of TNFα converting enzyme (TACE) Trafficking. TACE, a transmembrane metalloprotease involved in signaling of receptors/cytokines/growth factors/adhesion proteins, is upregulated in CD, resulting in a marked increase of membranous TNFα cleavage and inflammation. Initially, we measured TGFβRII shedding in plasma from CD patients and healthy controls (N=40 per group). We …


Applications For Machine Learning On Readily Available Data From Virtual Reality Training Experiences, Alec Moore Jan 2022

Applications For Machine Learning On Readily Available Data From Virtual Reality Training Experiences, Alec Moore

Electronic Theses and Dissertations, 2020-2023

The purpose of the research presented in this dissertation is to improve virtual reality (VR) training systems by enhancing their understanding of users. While the field of intelligent tutoring systems (ITS) has seen value in this approach, much research into making use of biometrics to improve user understanding and subsequently training, relies on specialized hardware. Through the presented research, I show that with machine learning (ML), the VR system itself can serve as that specialized hardware for VR training systems. I begin by discussing my explorations into using an ecologically valid, specialized training simulation as a testbed to predict knowledge …


An Anthropological Study Of The Effects Of The Covid-19 Pandemic On Drug Treatment In The United States, Abigail Shepherd Jan 2022

An Anthropological Study Of The Effects Of The Covid-19 Pandemic On Drug Treatment In The United States, Abigail Shepherd

Electronic Theses and Dissertations, 2020-2023

This thesis examined the extent to which the COVID-19 pandemic has affected the structure of drug treatment in the United States and how the effects have influenced the experience of undergoing and providing services in a variety of contexts. The COVID-19 pandemic emerged amid an opioid epidemic, which has taken the lives of over 564,000 Americans since the late 1990s. With overdose deaths increasing since the onset of the pandemic and government agencies responding with policy changes, recent research in the social sciences and on drug treatment services has necessarily shifted its focus to the effects of the pandemic on …


Cholera Transmission Dynamic Model With Environmental Impacts Of Plankton Reservoirs, Sweety Sarker Jan 2022

Cholera Transmission Dynamic Model With Environmental Impacts Of Plankton Reservoirs, Sweety Sarker

Electronic Theses and Dissertations, 2020-2023

Cholera is an acute disease that is a global threat to the world and can kill people within a few hours if left untreated. In the last 200 years, seven pandemics occurred, and, in some countries, it remains endemic. The World Health Organization (WHO) declared a global initiative to prevent cholera by 2030. Cholera dynamics are contributed by several environmental factors such as salinity level of water, water temperature, presence of plankton especially zooplankton such as cladocerans, rotifers, copepods, etc. Vibrio cholerae (V. cholerae) bacterium is the main reason behind the cholera disease and the growth of V. cholerae depends …


Team Virtuality And Psychological Safety: An Experiment, Moses Rivera Jan 2022

Team Virtuality And Psychological Safety: An Experiment, Moses Rivera

Electronic Theses and Dissertations, 2020-2023

Working from home as part of a virtual team has become the status quo for many workers due to the COVID-19 pandemic. Moreover, modern organizations require teams skilled at complex problem-solving, innovation, and adaptability. Psychological safety enhances these skills, by means of fostering an environment in which team members can fully engage and learn. Given the theoretical possibility that team virtuality may dampen the development of team psychological safety, the present study empirically investigated relationship between these two constructs. A hypothesized model was tested, in which team virtuality has an indirect effect on team psychological safety, via intrateam perceived other-to-self …

Inclusive Writing, Kairos, And Technical Communication: Defining Our Modern Age., Ramara Reisch

Electronic Theses and Dissertations, 2020-2023

A reoccurring topic in the TPC (technical/ professional communication) field has been the exclusion and marginalization of some audience members, especially those who are African American/ Black, Asian, Hispanic or Latino, LGBTQIA, and those with physical or mental disabilities. Throughout this thesis, I make connections between what has happened in the past and how it has contributed to the kairos of the TPC social justice turn. I explore the term "kairos" which is the timing and space in which something occurs and, depending on someone's delivery, they can create a persuasive and opportunist moment. The subject of including audiences into …


Exploring The Response To Covid-19 In Puerto Rico, Richard Colon Jan 2022

Exploring The Response To Covid-19 In Puerto Rico, Richard Colon

Electronic Theses and Dissertations, 2020-2023

In recent years Puerto Rico has faced a series of unfavorable events including financial turmoil, massive population loss, earthquakes, and droughts. These events had significantly impacted its resources and capacity to confront a major public health crisis. As such, Puerto Rico was expected to poorly manage the ongoing pandemic. Despite this, nearly all data surrounding the COVID-19 pandemic in Puerto Rico has indicated the contrary. The purpose of this study was to explore and understand the COVID-19 response in Puerto Rico. The Conservation of Resources theory guided the analysis of resource consumption and management of the Puerto Rican government and …


A Unified Tool For Adaptive Collocation Techniques Applied To Solving Optimal Control Problems, Bethany Kelly Jan 2022

A Unified Tool For Adaptive Collocation Techniques Applied To Solving Optimal Control Problems, Bethany Kelly

Electronic Theses and Dissertations, 2020-2023

In this work, a user-friendly MATLAB tool is introduced to solve nonlinear optimal control problems by applying collocation techniques using Coupled Radial Basis Functions (CRBFs). CRBFs are a new class of Radial Basis Functions combined with a conical spline r^5, which provides the advantage of insensitivity to the shape parameter while maintaining accuracy and robustness. To solve optimal control problems, software tools are often employed to implement numerical methods and apply advanced techniques to solving differential equations. Although several commercial software tools exist for solving optimal control problems, such as ICLOCS2, GPOPS, and DIDO, there are no options available that …

Un-Portalable! is an animated multimedia short film about two friends who become fused together after using a faulty teleporter. They attempt to conceal their deformity while simultaneously navigating a social situation with one of their friends. The main focus in the film is the concept that boundaries tend to become clearer as they begin to break. This conceptual focus merges into the visual theory of the film in which highly expressive character design and hybrid media utilization are driven by relational and narrative design choices. This film serves as a condensed pilot and proof of concept for a larger prospective …


The Loyalty Of The Lords Of Albret: An Investigation Of The Gascon Rolls At The Outset Of The Hundred Years War, Jason Delaney Jan 2022

The Loyalty Of The Lords Of Albret: An Investigation Of The Gascon Rolls At The Outset Of The Hundred Years War, Jason Delaney

Electronic Theses and Dissertations, 2020-2023

This thesis will examine the juxtaposition of the duchy of Gascony's importance to the Plantagenet Crown with the difficulties administering the region and protecting it from French interference during the late-thirteenth and early-fourteenth centuries, resulting in the necessity of securing the loyalty of Gascon nobles for assistance. The lords of Albret were powerful allies under Edward I (1272-1307), and their defection to the French under his son, Edward II (1307-1327), put Plantagenet Gascony in a vulnerable position when the Hundred Years War began in 1337. Resecuring the loyalty of Albret – and other powerful Gascon lords – was crucial for …


Distracted Driving And Pedestrians' Effects On Headway At Signalized Intersections, Bassel Elgamal Jan 2022

Distracted Driving And Pedestrians' Effects On Headway At Signalized Intersections, Bassel Elgamal

Electronic Theses and Dissertations, 2020-2023

Distracted driving and pedestrians pose one of the most difficult challenges to ensuring a safe and efficient transportation system. Modern communications have delivered greater convenience. However, this has come at the cost of attention spans. Safety has been thoroughly explored in terms of distracted driving and pedestrians. However, impacts on traffic operations have received minimal research attention. Few studies provided a theoretical mechanism on how intersection operations can be affected but failed to quantify the real-life impacts on traffic operations. Furthermore, new Florida laws prohibit cellphone usage while driving but is allowed when the vehicle is stationary, which may result …


Circulating Suburbia: Locating A Transnational Suburban Imagination In Post-War Periodicals, 1945-1970, Tyler Dick Jan 2022

Circulating Suburbia: Locating A Transnational Suburban Imagination In Post-War Periodicals, 1945-1970, Tyler Dick

Electronic Theses and Dissertations, 2020-2023

In this thesis I argue that a suburban cultural imagination developed transnationally during the post-war period (roughly 1945-1970) rather than as a cultural phenomenon largely associated with the 1950s United States. I situate the suburbs—in both their physical and cultural constructions—as my primary focus and discuss the suburb's influence on hegemonic culture by performing an in-depth comparison of the U.S. with another country with a long history of suburbanization—Australia. Given that the suburbs structure several social, cultural, economic, political, and historical vectors—which all in turn inform issues of gender, race, class, sexuality, and nationality—I focus on how the suburbs inform …


Digital Humanities & Community College Libraries: Opportunities And Challenges, Mia Tignor Jan 2022

Digital Humanities & Community College Libraries: Opportunities And Challenges, Mia Tignor

Electronic Theses and Dissertations, 2020-2023

Digital humanities study applies technological tools to the study of humanities topics and allows for the exploration of new questions in ways that were not possible using traditional research models. Librarians have been active participants of the field since its inception, as they explore new ways to critically engage with information organization and information literacy instruction, and most research that focuses on the intersection between these fields takes place within research universities . In contrast, there is very little research examining digital humanities work at the community college, which primarily offers associate degrees, vocational certificates, and other workforce based training. …

Igniting Interest?: Female Perceptions Of Communication Effectiveness In Public Safety Recruitment Campaigns, Ashley Papagni Jan 2022

Igniting Interest?: Female Perceptions Of Communication Effectiveness In Public Safety Recruitment Campaigns, Ashley Papagni

Electronic Theses and Dissertations, 2020-2023

Despite the potential for positive impacts resulting from a diverse workforce, fire departments across the country have struggled with the recruitment and hiring of minorities for decades, with women accounting for only 4.7% of its workforce (NFPA, 2020). Due in part to the limited diversity, the fire service tends to perpetuate the stereotypes of masculinity. There are three identified issues that are leading to the lack of female applicants in public safety positions, including the lack of diversity and inclusivity in Public Safety Organizations (PSOs), the absence of women in the role as firefighters, and the absence of recruitment strategies …

Promoting Covid-19 Vaccines Among Communities Of Color: An Analysis Of U.S. Minority Serving Higher Education Institutions’ Message Framing Strategies, Najma Akhther, Khairul Islam

International Crisis and Risk Communication Conference

This study examined how Historically Black Colleges and Universities (HBCUs) in the United States used framing as an issue management strategy in promoting COVID-19 vaccine. A content analysis of HBCUs’ (N = 268) COVID-19 vaccine-related messages showed that institutional leaders primarily used thematic frames over episodic frames. In other words, the COVID-19 vaccination was promoted as a community issue by emphasizing safety and well-being of the community. Black leaders’ vaccine communication mostly focused on background information, research data, and statistics related to vaccination and vaccine effectiveness. Such use of framing strategies may indicate black leaders’ trust and openness in vaccine …

The Perils Of The Boomerang Effect: White House Messaging To Deter Border Crossing Backfires, Mariely Valentin-Llopis, Jessica Delgado Jan 2022

The Perils Of The Boomerang Effect: White House Messaging To Deter Border Crossing Backfires, Mariely Valentin-Llopis, Jessica Delgado

International Crisis and Risk Communication Conference

The Boomerang Effect explains how a given persuasive message produces attitude change in the direction opposite to that intended. We seek to explain how the convergence of Central American migrants at the southwest border since 2014 is, in part, produced by the United States (U.S.) White House messaging misstep. We propose a bottom-up persuasive approach to effectively spread awareness of the dangers of unauthorized border crossing. Instead of state authority voices, local native voices can effectually convey the message. The bottom-up approach of persuasion is a foundational strategy to effectively design a public awareness campaign focusing on ethos. The objective …
