Gentrifried: The Foodways Of Neoliberal Urban Redevelopment In St. Louis, Elizabeth Schwartz

Dean James E. McLeod Freshman Writing Prize

Settler-invader colonialism is a type of colonization in which the colonizer displaces those indigenous to the region and then settles in the area, claiming it as their own. In their paper on settler-invader colonies, Johnston and Lawson argue: A key element in settler postcolonial theory is an examination of the processes by which emigrant European settlers ‘displaced’ the indigenous occupants. This displacement took many different forms. It was physical, geographical, spiritual, cultural, and symbolic. Indigenous peoples were characteristically moved from their traditional lands onto less desirable tracts of country…the displacement was, almost as importantly, cultural and symbolic as well as …

Effects Of Traffic Incidents On Adjacent Facilities And Alternative Re-Routing Strategies, Alican Karaer

UNF Graduate Theses and Dissertations

This study presents an analysis of detour operations as a concept of congestion management. Since a large portion of traffic delay emanates from traffic incidents, the goal of the study was to alleviate incident-induced impacts on freeways by diverting congested traffic on to adjacent roadway facilities. To balance the demand between freeway and arterial systems, optimization was required through Integrated Corridor Management (ICM). This thesis examines the justification and optimization of dynamic traffic routing strategies.

Previous studies have justified detour operations based solely on traffic simulation results. This study quantifies the impacts from freeway incidents on a parallel arterial roadway …

College Students With Autism Spectrum Disorders And Their Knowledge Of Self-Determination: A Study To Inform Educational Practices And Policies, Tara Rowe

UNF Graduate Theses and Dissertations

The number of students with autism spectrum disorders (ASD) attending postsecondary education has steadily increased in recent years. A need has been identified for campus administrators to better understand the needs of students with ASD (Becker & Palladino, 2016; Oswald, Winder-Patel, Ruder, Xing, Stahmer, & Solomon, 2017). In order to gain insight about students with ASD, research providing a foundation of understanding the unique characteristics and needs of this growing population must take place. By recognizing the need for further education and training, campus administrators may have opportunities to develop professional development trainings that could provide insight into understanding a …

Cloud computing helps decrease memory usage and improve battery life. Mobile cloud computing is a current and expanding research area focusing on methods that allow …

The Role Of Wave Self-Similarity In Nearshore Wave Spectra, Morgan M. Smith

UNF Graduate Theses and Dissertations

Nonlinear wave-wave interactions and wave breaking contribute to nearshore wave energy dissipation. These factors can be analyzed by the principles of wave self-similarity. The equilibrium range can be shown in wind-driven wave spectra that exist in the form ( ) and However, the appropriate methods used to determine this loss of energy are controversial. This study examines an approach that reinvestigates the self-similarity principles. Wave spectra with lower peak periods are dominated by nonlinear wave-wave interactions which produce a scaling in shallow water. This thesis investigates the relative role of spectral similarity in different conditions in the nearshore region of …

Effect Of Vessel-Generated Waves In Near Low Tide Conditions On Shorelines In The Intracoastal Waterways, Mackenzie Lee Sanchez

UNF Graduate Theses and Dissertations

Erosion is caused when there is a net loss of sediment in a coastal system, i.e. when the amount of sediment leaving a system is more than the amount of sediment entering that same system. This investigation will focus on vessel-generated waves and their effect on the shorelines of the Jacksonville, Florida Intracoastal Waterways near low tide conditions. The investigation conducted herein examines variations in turbidity and pressure measurements in response to passing vessels at a single site location previously selected in 2016. The primary water/shoreline interaction recorded during this investigation is located below the visible scarp (near low tide …

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 …

Relationship Between Concussion Symptom Clusters And Return-To-Play Time In College Athletes With Sports-Related Concussions: 2009-2010 To 2013-2014 Disc, Adrian Joseph Boltz

UNF Graduate Theses and Dissertations

Objectives To examine the relationship between Concussion Symptom Clusters (CSCs) and return-to-play time using a representative sample of U.S. college athletes with sports-related concussions.

Background Recent evidence regarding concussion symptoms have been observed to be an important element of concussion severity, and potentially a predictor of return-to-play time. However, there is a paucity of data examining the associations between Concussion Symptom Clusters (CSCs) and return-to-play time in the U.S. college athlete population.

Methods Data from the 2009-2010 to 2013-2014 academic years (n=1670) were obtained from the Datalys Center for Sports Injury and Prevention Inc. database. Exploratory factor analytic methods were …

Get Legitimate: Achievements Promote Recovery From Addiction Via Non-Addict Identity, Daniel Crutchfield

UNF Graduate Theses and Dissertations

Abstract

Despite decades of research, over 400 million people around the globe suffer from substance abuse and only 10% to 43% maintain abstinence after treatment. Social support, spirituality, self-regulation, and locus of control have all been examined for their efficacy and relationship with successful abstinence outcomes. Conceptually, educational/vocational achievement is believed to contribute to reforming an identity divorced from the previous lifestyle of active addiction. Educational and Vocational achievements as proxies for non-addict identity have only been investigated sporadically. The present study seeks to establish a quantitative link between successful long-term recovery and these types of goal-oriented achievements. A survey …

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 …

Particle Filters For State Estimation Of Confined Aquifers, Graeme Field

UNF Graduate Theses and Dissertations

Mathematical models are used in engineering and the sciences to estimate properties of systems of interest, increasing our understanding of the surrounding world and driving technological innovation. Unfortunately, as the systems of interest grow in complexity, so to do the models necessary to accurately describe them. Analytic solutions for problems with such models are provably intractable, motivating the use of approximate yet still accurate estimation techniques. Particle filtering methods have emerged as a popular tool in the presence of such models, spreading from its origins in signal processing to a diverse set of fields throughout engineering and the sciences including …

"Contra Haereticos Accingantur": The Union Of Crusading And Anti-Heresy Propaganda, Bryan E. Peterson

UNF Graduate Theses and Dissertations

This study assesses the intersection of crusading and heresy repression in the late twelfth and early thirteenth centuries. The event that encapsulates this intersection was the Albigensian Crusade, a two-decades long conflict that befell the south of France, or Occitania. The papacy, aligned with northern lords and other willing Christians, took up arms to defend the Church from the Cathar heresy’s corrupting influence. This conflict marked a new development in Christian acts of violence. While the Church had crusaded against many different enemies—even branding some as heretics—before 1209, the Church had never called a crusade for the explicit purpose of …

Impressions Of A Female Political Candidate Based On Political Party Affiliation, Candice J. Veilleux

UNF Graduate Theses and Dissertations

There is a gender gap in United States politics; men are over represented, and prioritize issues/policies differently compared with women. Stereotypes may be associated depending on group memberships. Stereotypes of men (competent) are consistent and stereotypes of women (warm) are inconsistent with politicians (competent). I examined stereotypes of major/non-major political parties, and how party affiliation affects whether stereotypes about men/male politicians/women/female politicians predict female politicians’ traits. Stereotype valence ascribed to political parties is important because people vote for a positively viewed party/representative. I assessed the strength and valence of stereotypes associated with political parties, and found major parties were viewed …

"Who Will Teach The Poor Little Ones To Say Their Prayers?" Catholics, Protestant, And Black Education In Reconstruction Era St. Augustine, Florida., Justin Stuart

UNF Graduate Theses and Dissertations

In 1968, the doors of St. Benedict the Moor’s school in St. Augustine, Florida, closed after nearly seventy years of service to members of the city’s African American community. But St. Benedict’s school represented a long tradition of black Catholic education in St. Augustine. Under Spanish rule, a boy’s school existed that offered equal education to blacks and whites. Florida’s possession by the United States complicated matters as territorial and state laws ended black education in the city, and the Catholic Church chose to side with the South over the issue of slavery in the United States. With the town’s …

Student Perceptions Of Police, Taylor Leigh Claxton

UNF Graduate Theses and Dissertations

Police-community relations are a frequently discussed topic in both academe and the media. Many factors are believed to influence individuals’ perceptions and views of law enforcement, including demographic variables (race and socioeconomic status), experiences with law enforcement, and media consumption. With an emphasis in the news and on social media regarding police misconduct or police brutality, this research seeks to inquire about college students' perceptions of law enforcement and racial injustice within the criminal justice system. While controlling for key demographic variables, this project specifically examines how individuals’ personal experiences with law enforcement and their exposure to news media and …

The Inevitability Of Decay: Disability In Ernest Hemingway's The Old Man And The Sea, Dominic Robin

UNF Graduate Theses and Dissertations

To many, Ernest Hemingway embodies a certain image of "masculinity," one centered around ability and physical performance. Such a narrative ignores the truly complicated and dynamic shape his understanding of the body took. Through an analysis of Hemingway's The Old Man and the Sea, I examine the form this ideology took in his later life, focusing particularly on Hemingway's evolved understanding of the body. Through this research, a more nuanced picture of Hemingway emerges, one that recognizes the complicated and dynamic nature his view of the "able" body took.

Implementation Of Cache Attack On Real Information Centric Networking System, Faustina J. Anto Morais

UNF Graduate Theses and Dissertations

Network security is an ongoing major problem in today’s Internet world. Even though there have been simulation studies related to denial of service and cache attacks, studies of attacks on real networks are still lacking in the research. In this thesis, the effects of cache attacks in real information-centric networking systems were investigated. Cache attacks were implemented in real networks with different cache sizes and with Least Recently Used, Random and First In First Out algorithms to fill the caches in each node. The attacker hits the cache with unpopular content, making the user request that the results be fetched …

Soil Improvement Using Microbial Induced Calcite Precipitation And Surfactant Induced Soil Strengthening, Matthew P. Davies

UNF Graduate Theses and Dissertations

Microbially induced calcite precipitation (MICP) has been used for a number of years as a technique for the improvement of various geological materials. MICP has been used in a limited capacity in organic rich soils with varying degrees of success. Investigators hypothesized that microbially-induced cementation could be improved in organic soils by using a surfactant. Varying amounts of Sodium Dodecyl Sulfate (SDS) were added to soils of varying organic content and a mixing procedure was used to treat these soils via MICP. Treated specimens were tested for unconfined compressive strength (UCS). Results appeared to show direct relationships between SDS content …

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 …

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 …

Vertical Distribution Of Meroplankton And Bivalve Competition In A Well-Mixed Estuary, Jennifer M. Raabe

UNF Graduate Theses and Dissertations

If we want to understand how meroplankton utilize the water column and how their vertical distribution may influence horizontal advection, it is important to study their behavior in the various environments where they exist. In a well-mixed system with physical cues dampened, and no vertical layering, these organisms will have to depend on environmental cues such as light, tidal current, and tide cycle, as well as their own swimming ability to migrate vertically. Plankton and water samples were collected at three depths (near surface, midwater, near bottom) during the summers of 2013 and 2014 from sites within the main channel …

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 …

Towards Designing Energy Efficient Symmetric Key Protocols, Sai Raghu Talluri

UNF Graduate Theses and Dissertations

Energy consumption by various modern symmetric key encryption protocols (DES,

3-DES, AES and, Blowfish) is studied from an algorithmic perspective. The work

is directed towards redesigning or modifying the underlying algorithms for these

protocols to make them consume less energy than they currently do. This research

takes the approach of reducing energy consumption by parallelizing the

consecutive memory accesses of symmetric key encryption algorithms. To achieve

parallelization, an existing energy complexity model is applied to symmetric key

encryption algorithms. Inspired by the popular DDR3 architecture, the model assumes

that main memory is divided into multiple banks, each of which can …

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 …

Learning Strategies Employed By College Aged Students With Disabilities: The Link Between Metacognition, Motivation, And Working Memory, Michael Rodriguez

UNF Graduate Theses and Dissertations

The aim of this study is two-fold. First, we want to understand the levels of metacognitive awareness of learning strategies in undergraduates with learning disabilities. Previous research states that recall is the most effective method of studying, but most students prefer to reread their notes or textbook which is ineffective. Second, we want to explore the link between Working Memory and metacognitive awareness of learning strategies in undergraduates with learning disabilities. The learning strategies that college students with and without disabilities is examined, we found that students in both groups preferred the usage of the same strategies equally. The most …

Parent Perceived Stress And Child Temperament: Qualities That Facilitate Or Impede Child Developmental Outcomes, Rebekah Faith Klempin

UNF Graduate Theses and Dissertations

Effective parent-child relationships contribute to the development of well-adjusted children. Taxing personal and situational factors encumber a caregiver’s capacity for responsivity with his or her child. The purpose of the present study was to identify interpersonal factors that impact child outcomes in low socioeconomic status family populations. Data was collected in northeast Florida Head Start centers from 219 low income, at-risk caregivers and their children ages one and a half through almost five. Parents completed questionnaires on parent perceived stress, child temperament, and child developmental outcomes.
