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.

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 …

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 …

Radiation Therapy In Metastatic Neuroblastoma, Meenu Gupta, Anupam Dhasmana

School of Medicine Publications

Neuroblastoma is the commonest extracranial solid tumor in children, and metastasis at presentation is seen in more than 50% of cases. The role of radiotherapy as a palliative modality in patients with advanced neuroblastoma provides better symptomatic relief. Palliative radiotherapy dose schedules can be given either in single hypofractionation from 4 to 8 Gy or fractionated radiotherapy that can range from 21 to 30.6 Gy. Doseresponse relationship trend has been reported in the palliative setting of bone metastasis. Because of the proximity of tumor to critical organs, serious adverse effects can be avoided with conformal techniques. Although currently there is …

Investigating The Causes And Cures For Unclear Scholarly Writing, Marlene Ingrid Mahony

Doctoral Dissertations

This qualitative dissertation investigated possible causes and cures for unclear scholarly writing. For this study, a stipulative definition of unclear scholarly writing, or “academese,” is that the language tends to be vague and verbose. The problem, according to the included literature, is that people who use or accept vague language have less academic, social, professional, and civic power. Academese, some say, can detach readers and that can accordingly diminish collective exchange. Because higher education is meant to share knowledge, promote agency, and prepare students to communicate powerfully within and beyond the university, this study researched the causes and cures of …

From Seeds To Shoreline®: A Place-Based Approach To Impacting Student Engagement And Achievement, Molly Lloyd

Theses and Dissertations

Place-based education refers to pedagogy that connects student learning with the local environment and students’ lives. Educators’ preoccupation with standardized test scores have increased the disconnect between formal education and student’s life experiences. Schools have developed systems of learning in isolated subjects through reading texts, listening to lectures, or watching videos rather than authentic, experiential learning. School districts have embraced a STEM (science, technology, engineering, and science) approach to education as a way of invigorating student learning. There are many approaches to integrating, hands-on, inquiry-based science lessons. As science PASS test scores have declined, educators are examining best STEM instructional …

Attitudes And Thoughts On Tone Quality In Historic Piano Teaching Treatises, Jeongsun Lim

Theses and Dissertations

Various approaches to the perception and production of tone quality on the piano have been suggested throughout the history of piano pedagogy. Tone quality differences are controversial among physicists, acoustic scientists, pianists, and piano pedagogues. Studies and research began to investigate tone quality with scientific experiments, and physicists and scientists asserted that differences in tone quality are differences in pitch, intensity, duration, and in combinations of tone and noise. They asserted that tone quality does not change with different physical touches and the pianist cannot control the quality of the tone. However, pianists and pedagogues believed that pianists have control …
