Also investigated were the relationships between faculty trust and demographic characteristics …

Development Of Forward And Inversion Schemes For Cross-Borehole Ground Penetrating Radar, Donald Jones

UNF Graduate Theses and Dissertations

Tomography is an imaging technique to develop a representation of the internal features of material using a penetrating wave, such as an electromagnetic wave. The calculation method used is an example of an inverse problem, which is a system where the input and the output are known but the internal parameters are not. These parameters can be estimated by understanding the responses of a penetrating wave as it passes through the unknown media. A forward problem is just the opposite; the internal structure and input penetrating wave is known and the output is determined. For both forward and inverse problems, …

Teacher Perspectives Regarding The Pedagogical Practices Most Culturally Responsive To African American Middle School Students, Robert James Mcgill

UNF Graduate Theses and Dissertations

This dissertation examines teacher’s perspectives regarding the classroom strategies,

behaviors, and approaches they believed best support the development of African American students. Educator perceptions are valuable to understand because perceptions and attitudes undergird behavior and practices. This study focused on perceptions of teachers toward pedagogical strategies, approaches, and teacher behaviors that perceived to best support African American students because of the persisting achievement gap between African American students and their White, middle class counterparts.

Culturally Relevant Pedagogy was used as the theoretical framework for this study as it describes approaches to teaching students from historically marginalized groups in ways that …

Putting The “Gay” In Gamers: Increasing Identification With Homosexuals Through Video Games, Matthew D. Olah

UNF Graduate Theses and Dissertations

Priming out-groups and taking the perspective of out-group members increases implicit and explicit identification with out-groups. Because the popularity of video games has increased dramatically over the past few decades and they have become an influential form of media, the current study investigated video games as another potential strategy to increase identification with and reduce prejudice against out-groups. Specifically, I investigated how manipulating the sexual orientation of the video game character participants used influenced implicit and explicit identification with homosexuals and implicit and explicit prejudice against homosexuals. Additionally, I investigated whether implicit and explicit identification with homosexuals would mediate the …

Spatial Variation In Fishery Exploitation Of Mature Female Blue Crabs (C. Sapidus) In Chesapeake Bay, Corey Travis Corrick

UNF Graduate Theses and Dissertations

From 2008 to 2012, the total U.S. commercial landings of blue crabs (Callinectes sapidus Rathbun, 1896) averaged over 173 million lbs. Chesapeake Bay and its tributaries are important contributors to this fishery, providing greater than 30% of national commercial landings annually. In Chesapeake Bay, C. sapidus exhibits a complex life cycle in which mated females migrate to the saline waters of the Bay mouth to spawn. During migration, females can traverse multiple management jurisdictions, complicating effective management of this important fishery. Sustained declines in harvest have led to management strategies focused on protecting the female spawning stock in an …

Hard Copy Versus #Hashtag: Examining The Channels Of Terrorist Propaganda, Evan Copello

UNF Graduate Theses and Dissertations

In recent years, terrorism and radicalization has been a consistent issue that many countries have faced. The Islamic State of Iraq and Syria (ISIS) has been the most recent in a long trail of organizations that have sought to strike terror against the western world. However, ISIS is distinguished from other groups, like Al-Qaeda, in that ISIS supports a complex propaganda machine. Although ISIS is not the first organization to use the social media platform, they are the first to use it with such diversity. The two main channels that ISIS uses to spread their propaganda messages are through social …

Results indicated that transfer procedures may be helpful in generalizing manding for a child …

The Truth Is Out There: The Use Of Conspiracy Theories By Radical Violent Extremist Organizations, Gregory Rousis

UNF Graduate Theses and Dissertations

This paper sought to examine conspiracy theory (CT) use across three types of groups: radical violent extremists (RVE), non-violent extremists, and moderates. Using the theory of significance quest, or the desire for one’s life to have meaning (Kruglanski, Chen, Dechesne, Fishman, & Orehek, 2009), I sought to determine whether RVE groups were more likely to use CTs, invoke need for cognitive closure (NFCC) via the use of time pressure, elicit anomie, and promote significance quest through violence than the other groups. Using text analysis software, I pulled passages from six groups – two from each level of extremism - that …

Development Of A One-Way Coupled Diffraction/Trapped Air Model For Predicting Wave Loading On Bridge Superstructure Under Water Wave Attack, Christian Hillary Matemu

UNF Graduate Theses and Dissertations

In recent years, a number of researchers have applied various computational methods to study wind wave and tsunami forcing on bridge superstructure problems. Usually, these computational analyses rely upon application of computational fluid dynamic (CFD) codes. While CFD models may provide reasonable results, their disadvantage is that they tend to be computationally expensive. During this study, an alternative computational method was explored in which a previously-developed diffraction model was combined with a previously-developed trapped air model under worst-case wave loading conditions (i.e. when the water surface was at the same elevation as the bottom bridge chord elevation). The governing equations …

Coupling Radio Frequency Energy Via The Embedded Rebar Cage In A Reinforced Concrete Structure For The Purpose Of Concrete Degradation Sensing, Ryan Campiz

UNF Graduate Theses and Dissertations

This study focuses on utilizing an energy harvesting system in which a dedicated Radio Frequency (RF) power source transmits RF power via rebar in a reinforced concrete column. The RF power is received and decoupled by a receiver, and is then rectified, boosted, and stored as electrical energy in a supercapacitor, later to be used to make measurements, process data, and communicate to the source via rebar. Two design attempts are presented in this study: (a) one uses single line conduction at 2.4 GHz for RF power transfer; (b) the other uses a more conventional two-line conduction at 8.0 kHz …

Twitter Use During Hurricane Irma: How The Local Government Agencies Amplify And Attenuate Risk Factors For The Vulnerable Populations, Elizabeth Ann Mccarthy

UNF Graduate Theses and Dissertations

Twitter has become a popular channel for local governments to explore crisis communication during a hurricane. Local governments use Twitter to distribute crisis messages to the public, and are able to amplify or attenuate risk perception. Many factors attribute to individuals’ risk perception including control, choice, children, novelty, and risk-benefit tradeoff. The Social Amplification of Risk Framework (SARF) provides a guide to understanding the intensifying or weakening of these risk messages. While these crisis messages are directed to the general public, the local governments may be neglecting information for the vulnerable populations. In order to prepare for a hurricane, vulnerable …

Evaluation Of Traffic Incident Timeline To Quantify The Performance Of Incident Management Strategies, Henrick Joseph Haule

UNF Graduate Theses and Dissertations

Transportation agencies are introducing new strategies and techniques that will improve traffic incident management. Apart from other indicators, agencies measure the performance of the strategies by evaluating the incidents timeline. An effective strategy has to reduce the length of the incident timeline. An incident timeline comprises various stages in the incident management procedure, starting when the incident was detected, and ending when there is the recovery of normal traffic conditions. This thesis addresses three issues that are related to the traffic incident timeline and the incident management strategies.

First, co-location of responding agencies has not been investigated as other incident …

Detection Of Cyanotoxins (Microcystins/Nodularins) In Hepatic Tissues And Epidermal Mats Of Stranded Bottlenose Dolphins (Tursiops Truncatus) In Northeast Florida, Amber Brown

UNF Graduate Theses and Dissertations

The St. Johns River (SJR; Jacksonville, FL, USA) is a large, brackish, estuarine system characterized by considerable anthropogenic pollution, recurrent harmful algal blooms (HABs), and diverse toxin-producing cyanobacteria. The most prevalent toxins in SJR water samples are microcystins/nodularins (MCs/NODs). Additionally, the SJR provides critical habitat for a genetically and behaviorally distinct estuarine community of bottlenose dolphins (Tursiops truncatus) that routinely uses and strands in low mesohaline and oligohaline areas of the river. This population has been subject to two unusual mortality events (UME) since 2010 and has since been described as having substantial declines in population health, characterized …

Tetratricopeptide 39c (Ttc39c) Is Upregulated During Skeletal Muscle Atrophy And Is Necessary For Muscle Cell Differentiation, Caleb Hayes

UNF Graduate Theses and Dissertations

Ttc39c has been identified as a novel gene in skeletal muscle that is upregulated in response to neurogenic atrophy in mice. Quantitative PCR and Western blot analysis confirmed that Ttc39c is expressed in both proliferating and differentiated muscle cells. Furthermore, comparison of Ttc39c expression in undifferentiated and differentiated C₂C₁₂ cells demonstrated that Ttc39c levels peak in early differentiation, but decreases as cells become fully differentiated myotubes. The transcriptional regulation of Ttc39c was examined by cloning promoter fragments of the gene and fusing it with the SEAP reporter gene. The Ttc39c reporter gene constructs were transfected into muscle …

Treatment Analysis Of A Captive Male Jaguar (Panthera Onca), Megan Colleen Morris

UNF Graduate Theses and Dissertations

Large carnivores in human care have been reported to engage in stereotypic behaviors. Such behavior is thought to be correlated with high stress levels, in part, due to captive environments limiting opportunities for functional consequences and environmental stimuli. Moreover, there are several arguments stating that stereotypic behaviors can be indicative of poor welfare, as they can often have severe negative emotional and physical effects on the animal. The first portion of this study included a five-phase treatment analysis which evaluated whether environmental manipulations decrease the frequency of stereotypic behaviors including pacing, over-grooming and tail-sucking exhibited by a single male jaguar …

Potential Replacement Of The Us Navy's Rapid Penetration Test With The Method Of Multichannel Analysis Of Surface Waves, William Fletcher

UNF Graduate Theses and Dissertations

The United States Navy (USN) currently utilizes a Rapid Penetration Test (RPT) on both land and in water as the means to determine whether sufficient soil bearing capacity exists for piles in axial compression, prior to construction of the Elevated Causeway System (Modular) [ELCAS(M)] pile-supported pier system. The USN desires a replacement for the RPT because of issues with the method incorrectly classifying soils as well as the need to have a less labor-and-equipment-intensive method for geotechnical investigation.

The Multichannel Analysis of Surface Waves (MASW) method is selected herein as the potential replacement for the RPT. The MASW method is …

Self-Monitoring And Friendship: Individual Differences In Relationship Dissolution, Michael Yoho

UNF Graduate Theses and Dissertations

High self-monitors choose as friends skilled activity partners, whereas low self-monitors select friends who are similar in attitude and values. We hypothesized that (a) as self-monitoring increased, individuals would identify the loss of shared interest as the cause for dissolving a former friendship and (b) as self-monitoring decreased, individuals would identify the loss of shared attitudes and values as the cause for dissolving a former friendship. One-hundred sixty one (82 males, 79 females) participants were recruited from MTurk. Participants were prompted with a forced choice measure to identify one of two reasons why a past close friendship dissolved. For one …
