Qualitative methods were utilized to analyze exceptional student education (ESE) policy manuals in …


Far-Infrared Bands In Plasmonic Metal-Insulator-Metal Absorbers Optimized For Long Wave Infrared, Rachel Evans Jan 2018

Far-Infrared Bands In Plasmonic Metal-Insulator-Metal Absorbers Optimized For Long Wave Infrared, Rachel Evans

Electronic Theses and Dissertations

Metal–insulator–metal (MIM) resonant absorbers comprise a conducting ground plane, a thin dielectric, and thin separated metal top-surface structures. Long-wave infrared (LWIR) fundamental absorptions are experimentally shown to be optimized for a ratio of dielectric thickness to top-structure dimension t/l > 0.08. The fundamental resonance wavelength is predicted by different analytic standing-wave theories to be ~2nl, where n is the dielectric refractive index. Thus, for the dielectrics SiO2, AlN, and TiO2, l values of a few microns give fundamentals in the 8-12 micron LWIR wavelength region. Agreement of observed fundamental resonance wavelength with theory is better for t/l > ~0.2. Harmonics at shorter …

Electronic Theses and Dissertations

This study investigated the minority carrier properties of wide and narrow bandgap semiconductors. Included specifically are wide bandgap materials GaN and β-Ga2O3, and narrow bandgap InAs/GaSb type-II strain-layer superlattice. The importance of minority carrier behavior in bipolar device performance is utmost because it is the limiting component in current conduction. The techniques used to determine minority carrier properties include electron beam induced current (EBIC) and cathodoluminescence (CL) spectroscopy. The CL spectroscopy is complemented with time-resolved CL (TRCL) for direct measurement of carrier radiative recombination lifetime. The minority carrier properties and effect of high energy radiation is explored. The GaN TRCL …


Alcohol Pathology And The Triarchic Model Of Psychopathy: The Role Of Protective Behavioral Strategies And Impulsivity, Matthew Kramer Jan 2018

Alcohol Pathology And The Triarchic Model Of Psychopathy: The Role Of Protective Behavioral Strategies And Impulsivity, Matthew Kramer

Electronic Theses and Dissertations

OVERVIEW: Psychopathy has been an area of growing interest in psychology for the last half century. Currently, the most common conceptualization of psychopathy breaks it down into two factors: primary and secondary psychopathy. More recently, psychopathy has been viewed through a more nuanced model, the Triarchic Model of Psychopathy. The present study examines the relationship between the three facets of the Triarchic Model and alcohol pathology via aspects of impulsivity and Protective Behavioral Strategies (PBS). METHOD: A college student sample of n = 967 individuals who endorsed consuming alcohol completed surveys regarding the Triarchic Model, impulsivity, PBS use, and alcohol …


Anti-Capitalism In The Contemporary Age: The Case Of The United Socialist Party Of Venezuela, William Maddens Jan 2018

Anti-Capitalism In The Contemporary Age: The Case Of The United Socialist Party Of Venezuela, William Maddens

Electronic Theses and Dissertations

Since the collapse of the Soviet Union in 1991, the popularity of anti-capitalist parties around the world has fallen. However, there are still surviving anti-capitalist political parties that survived this fall. In examining these parties, it must be determined whether they have any fresh ideas to overcoming the challenges of transitioning to a socialist society, and if they have any answers to the problems that plagued past attempts at socialism. One such party that has enjoyed much electoral success is the United Socialist Party of Venezuela. When taking a look at party programs, platforms, and statements made by party leaders, …


Altruistic Punishment Theory And Inter-Group Violence, Clayton Besaw Jan 2018

Altruistic Punishment Theory And Inter-Group Violence, Clayton Besaw

Electronic Theses and Dissertations

This dissertation explores the role of altruistic punishment, the act of punishing outsiders perceived to harm members of one's group at a personal cost, in explaining individual motivations to participate in inter-group violence. It first develops a social theory of this type punishment. This theory argues that an egalitarian social logic may be key to understanding motivations of parochial altruism, and that one's social environment may influence thresholds of anger needed to induce punishment behavior. Empirically, it conducts two survey-experimental studies. The first experiment utilizes subject partisan identity in the context of American politics and hypothetical acts of violence to …

This bioarchaeological thesis explores the prevalence and patterning of osteoarthritis between individuals buried at a Late Medieval Necropolis and a church Crypt built in the 19th century at the Mistihalj site in Bosnia and Herzegovina to understand the physiological effects of their peasant agro-pastoralist lifestyle. Composite scores of osteoarthritis were generated for visual observations of upper limb joints (shoulder, elbow, and wrist) and lower limb joints (hip, knee, and ankle) of 37 female and 39 male adult (between 20 and 50 or more years of age) …


Deciphering The Role Of Adrenergic Hormones In Embryonic Cardiac Calcium Signaling And Metabolism, Jessica Peoples Jan 2018

Deciphering The Role Of Adrenergic Hormones In Embryonic Cardiac Calcium Signaling And Metabolism, Jessica Peoples

Electronic Theses and Dissertations

The adrenergic hormones norepinephrine (NE) and epinephrine (EPI) are critical regulators of mammalian cardiovascular physiology. NE and EPI mediate stress responses to enhance cardiovascular function, however dysregulation of adrenergic signaling leads to heart failure, congenital heart malformations, and sudden cardiac death. Adrenergic hormone-expressing cells were found in the early embryonic heart, and NE has been determined essential for embryonic cardiac development. Despite extensive work in adults, the regulatory roles and adrenergic targets of these hormones during embryonic cardiac development have not yet been fully determined. Prior transcriptomic studies from our lab showed that expression of signal transduction and metabolic genes …


Exacerbation Of Δefp Sickness In Escherichia Coli By An Uncharacterized Rna Helicase, Robert Wingo Jan 2018

Exacerbation Of Δefp Sickness In Escherichia Coli By An Uncharacterized Rna Helicase, Robert Wingo

Electronic Theses and Dissertations

In Escherichia coli, growth is rate-limited by translation capacity [1]. Stalled ribosomes have profound effects on a cell such as altered mRNA abundance, decreased ribosome availability, and an imbalanced proteome. The absence of elongation factor P (EF-P), a universally conserved transpeptidation enhancer, presents an extreme example of this scenario, wherein ribosomes accumulate disproportionately onto messages that are more slowly translated and cell growth becomes notably impaired. We discovered that faster-growing cells arise spontaneously in Δefp cultures, suggesting that translation defects could be circumvented by mutating other genes. This thesis presents a genetic and biochemical analysis of a mechanism Δefp cells …

In particular, students in the fifth grade at CFSD were examined in relation to the gains made on their end-of-year statewide mathematics assessment, known as the Florida Standards Assessment (FSA Math). Per i-Ready®, students who use i-Ready® Mathematics Instruction for a minimum of 45 minutes per subject per week for at least 25 weeks show significantly greater gains than those who do not (Curriculum Associates, 2017b). Therefore, two propensity …


Design And Production Of Calculus Assessments, Lorna Wenzel Jan 2018

Design And Production Of Calculus Assessments, Lorna Wenzel

Electronic Theses and Dissertations

The AP Calculus program at Green High School was not adequately preparing students for college level calculus as more than 80 percent of the students failed the AP exam. The students were concurrently receiving high marks on in-class assessments. Hence, the in-class assessments were not good indicators of students calculus understanding according to the AP standards. A needs assessment was conducted, focusing on the difference in high school and college calculus, how to assess calculus and where Green High School's assessments were falling short. More research was conducted to examine the college Board expectations of calculus learning. A content matrix …


International Saudi Female Students' Experiences Of Acculturation During Their Study At An American Public University In The South (Apus), Hnan Alzahrani Jan 2018

International Saudi Female Students' Experiences Of Acculturation During Their Study At An American Public University In The South (Apus), Hnan Alzahrani

Electronic Theses and Dissertations

According to my literature review and my reflection of its meaning, few studies have been conducted that explore the adjustment and acculturation experiences of female international students in US colleges and universities specifically on Saudi female students. Therefore, this study explored the academic and socio-cultural experiences of Saudi female students before and after arriving in the US. Furthermore, this study identified the sources of acculturative stress and Saudi female students' successful strategies for coping with these stressors. Eight Saudi female students participated in one-on-one semi-structured interviews and Moustakas' (1994) transcendental phenomenology was utilized in analyzing students' voices. During the data …


Qualitative And Quantitative Elemental Composition Analysis Of The Surrounding Pollen Coating Via Icp-Ms, Brandy Voyer Jan 2018

Qualitative And Quantitative Elemental Composition Analysis Of The Surrounding Pollen Coating Via Icp-Ms, Brandy Voyer

Electronic Theses and Dissertations

Pollen evidence has proven to be a powerful forensic tool to trace a suspect or item to a victim or a crime scene. This is possible because it is microscopic, abundant in nature, resistant to degradation and decay; it presents dispersal patterns that can be used to generate a 'fingerprint' within specific areas, and has illustrated a unique morphology that can be used to classify species. While the pollen grain morphology has been extensively used to characterize the specific species, not much has been investigated as pertains to the coating that surrounds the pollen grain aside from it being categorized …


The Tragic City: Black Rebellion And The Struggle For Freedom In Miami, 1945-1990, Porsha Dossie Jan 2018

The Tragic City: Black Rebellion And The Struggle For Freedom In Miami, 1945-1990, Porsha Dossie

Electronic Theses and Dissertations

This thesis examines the creation of South Florida's tri-ethnic racial hierarchy during the postwar period, from 1945-1990. This racial hierarchy, coupled with discriminatory housing practices and police violence, created the necessary conditions for Dade County's first deadly uprising in 1968. Following the acquittal of several officers charged in the killing of an unarmed black businessman, a second uprising in 1980 culminated in three days and three nights of violent street warfare between law enforcement and black residents in Miami's northwest Liberty City neighborhood. The presence of state sanctioned violence at the hands of police in Liberty City set the stage …


Sanford, Debary Hall And The New South Movement In Central Florida, Sarah Thorncroft Jan 2018

Sanford, Debary Hall And The New South Movement In Central Florida, Sarah Thorncroft

Electronic Theses and Dissertations

The so-called New South movement coincided with national industrialization in the Gilded Age and Progressive Era. In the New South, modernization focused on the development of small diversified farms, mills that processed cotton and tobacco, and small cities that connected the countryside to national markets and provided area residents with mass produced goods. Florida's experience and more specifically development around Lake Monroe in Central Florida complicates and expands our understanding of the New South. Located in what was considered a frontier area, Sanford on the south shore of the lake and DeBary Hall on the north shore illustrate the development …


Quasi-Gorenstein Modules, Alexander York Jan 2018

Quasi-Gorenstein Modules, Alexander York

Electronic Theses and Dissertations

This thesis will study the various roles that quasi-Gorenstein modules and their properties play in the study of homological dimensions and linkage of modules. To that effect we begin by studying these modules in their own right. An R-module M of grade g will be quasi-Gorenstein if ExtiR(M, R) = 0 for i 6= g and there is an isomorphism M ∼= ExtgR(M, R). Such modules have many nice properties which we will explore throughout this thesis. We will show they help extend a characterization of diagonalizable matrices over principal ideal domains to more general rings. We will use their …

Analysis And Design Of Non-Hermitian Optical Systems, Ali Kazemi Jahromi Jan 2018

Analysis And Design Of Non-Hermitian Optical Systems, Ali Kazemi Jahromi

Electronic Theses and Dissertations

From a very general perspective, optical devices can be viewed as constructions based on the spatial engineering of the optical index of refraction. Sculpting the real part of the refractive index produces the wide variety of known passive optical devices, such as waveguides, resonators, gratings, among a plethora of other possibilities for managing the transport of light. Less attention has been directed to engineering the imaginary part of the refractive index – that is responsible for optical gain and absorption – in conjunction with the real part of the refractive index. Optical gain is the building block of amplifiers and …


Acute Effects Of Placebo And Open-Label Placebo Treatments On Muscle Strength, Voluntary Activation, And Neuromuscular Fatigue., Alina Swafford Jan 2018

Acute Effects Of Placebo And Open-Label Placebo Treatments On Muscle Strength, Voluntary Activation, And Neuromuscular Fatigue., Alina Swafford

Electronic Theses and Dissertations

Placebo treatments have long been used to study the psychological effects of expectancy and conditioning on an inert intervention. Interestingly, open-label placebo treatments (i.e., directly telling subjects they are receiving an inactive intervention) have recently shown promise in minimizing pain in clinical patient populations. We utilized a repeated measures design to examine the acute effects of placebo, open-label placebo, and control treatments on muscle strength and voluntary activation (Experiment #1), as well as neuromuscular fatigue (Experiment #2). Twenty-one untrained males (n=11) and females (n=10) visited the laboratory on three occasions to receive each treatment in a randomized, counter-balanced manner. All …


Academic Advisors' Attitudes Toward Students Experiencing Mental Health Issues, Danielle Aming Jan 2018

Academic Advisors' Attitudes Toward Students Experiencing Mental Health Issues, Danielle Aming

Electronic Theses and Dissertations

As students continue to pursue higher education, the potential for them to experience mental health issues will exist (National Alliance on Mental Illness, 2011; Center for Collegiate Mental Health, 2012; Gruttadaro & Crudo, 2012; Salzer, 2012; Center for Collegiate Mental Health, 2013). When entering a new environment, students will look to make connections with the institution; one of these connections can be with an academic advisor (Harper & Peterson, 2005; Harper & Wilson, 2010; Kuh, 2011; Pearson, 2012). It is important for individuals experiencing mental health issues to make connections to the institution so that they are more likely to …


Regulation Of Extra-Pituitary Prolactin In Monocytes And Macrophages, Richard Barrett Jan 2018

Regulation Of Extra-Pituitary Prolactin In Monocytes And Macrophages, Richard Barrett

Electronic Theses and Dissertations

Recently it has been shown that leukocytes are capable of producing prolactin (PRL). Evidence of extra-pituitary PRL (ePRL) production is so far been limited to primates and is not shared across other mammal species such as mice and rats. While ePRL is characterized as an identical protein to traditional pituitary PRL, it is controlled under an alternative promoter and is thus regulated differently from pituitary PRL. Little is known about what regulates ePRL or its direct role in human physiology, but given that PRL has well over 300 described functions, it is likely that the autocrine and paracrine effects of …


An Examination Of Beta Diversity Indices And Their Predictors In Two Large-Scale Systems, Philip Schroeder Jan 2018

An Examination Of Beta Diversity Indices And Their Predictors In Two Large-Scale Systems, Philip Schroeder

Electronic Theses and Dissertations

Biodiversity is what conservation biology was developed to conserve. It is the physical manifestation of life as a concept and, be it for practical or idealistic reasons, all conservationists seek to protect or, in some cases, enhance it. Because of its monolithic importance to the field, much effort has been expended trying to better measure and understand it. Recently, greater attention has been paid to the partition of diversity; the observation that the total diversity of a system (γ) can be broken down into within-site diversity (α) and between-site diversity (β). In particular, it has been noticed that the β …


Effects Of Electronic Media Messages On The Perceived Self-Efficacy Of Pedestrian Commuters Living In The Unincorporated Central Florida Community Of Conway, Daniel Stephens Jan 2018

Effects Of Electronic Media Messages On The Perceived Self-Efficacy Of Pedestrian Commuters Living In The Unincorporated Central Florida Community Of Conway, Daniel Stephens

Electronic Theses and Dissertations

Urban pedestrianism is increasingly perceived as a dangerous form of travel. While roadway design has been historically scaled to cars instead of people, planning professionals are now re-thinking their approach to make roads more inclusive for all travelers. Scholars, however, have learned harbored fear can trump behavior even under ideal travel conditions. Such fear can adversely impact perceived pedestrian self-efficacy, which is the self-generated internal assessment or belief in a traveler's agentive abilities to navigate the travel environment. The challenge thus becomes twofold: improve the built environment while bolstering traveler confidence. The following study, therefore, employed a qualitative phenomenological research …


Leader Psychology And Civil War Behavior, Gary Smith Jan 2018

Leader Psychology And Civil War Behavior, Gary Smith

Electronic Theses and Dissertations

How do the psychological characteristics of world leaders affect civil wars? Multiple studies have investigated how the personalities and beliefs of world leaders affect foreign policy preferences and outcomes. However, this research has yet to be applied to the intrastate context, which is problematic, given the growing importance of civil wars in the conflict-studies literature. This dissertation project utilizes at-a-distance profiling methods to investigate how leaders and their psychological characteristics can affect the likelihood, severity, and duration of civil conflicts. The findings of this research provide further support for the general hypothesis that leaders can, and often do, matter when …


The Intersection Of Race And Class In Maternity Leave: Who's Left Out?, Christine Ittai Jan 2018

The Intersection Of Race And Class In Maternity Leave: Who's Left Out?, Christine Ittai

Electronic Theses and Dissertations

Maternity leave is a critical work-family policy that affects over two-thirds of the working U.S. female population. Although it has been studied extensively, especially since the passage of the Family and Medical Leave Act of 1993, the majority of the research has focused on White, middle-class, married, and educated working mothers. There is a plethora of information about access to maternity leave, utilization of maternity leave, length of maternity leave, and compensation during leave. However, there are several limitations in the research. A majority of studies use outdated datasets; measure family leave as a proxy for maternity leave; study paid …


Reimagining Composition One As A Course In Storytelling Across Disciplines Using New Media, Angel O'Keeffe Jan 2018

Reimagining Composition One As A Course In Storytelling Across Disciplines Using New Media, Angel O'Keeffe

Electronic Theses and Dissertations

This dissertation focuses on the role that College Composition courses can and should play in addressing the digital divide and the literacy divide. For this project, digital divide refers to the space between those students who have opportunity to participate in online discourse communities and to contribute to the collective intelligence described by Henry Jenkins and those who have not had this opportunity even though they do have access to current technology. The literacy divide discussed is created when literacy is defined simply as the ability to read and write. Students need to be visually, digitally, and technologically literate. In …

A Qualitative Analysis Of Key Concepts In Islam From The Perspective Of Imams, Chandler Dobiyanski

Electronic Theses and Dissertations

The continuous occurrence of terrorist attacks in the name of Islam has shown this ideology and its tenets are at least somewhat connected to jihadists committing attacks in its name. This ideology in terms of 13 themes was investigated by the researcher in 58 sermons outlined in the tables in the appendix. These themes include: brotherhood, death, freedom, human rights, justice and equality, love, oppression, peace and treaty, self-defense, sin, submission, terrorism and truth vs. lies. The researcher used a sample of 10 sermons from U.S.- born imams and 10 sermons from foreign-born imams as the basis for the analysis …


Violence, Religion And Politics: The Late Republic And Augustan Age, Matthew Tuggle Jan 2018

Violence, Religion And Politics: The Late Republic And Augustan Age, Matthew Tuggle

Electronic Theses and Dissertations

Religion in the Late Republic was fused to politics. This study considers the relationship between violence, religion, and politics in the Late Republic and Augustan Age. It contends that Roman religion could encourage or discourage violence based upon the circumstances. The strain of Roman expansion on its political and religious institutions contributed to the civil discord that characterized the Late Republic, which created circumstances that were flexible enough for perspectives on each side to see the violence as justified. The ambition of a tribune, a sacrosanct office, could lead to circumvention of the traditional practices of the Senate, causing a …
