This thesis addresses the responses and subsequent roles of American military physicians in Post- WWII Germany, from March 1945 to January 1950. Physician roles include medical practice both within and outside of their specialties, hospital administration, and work in Prisoner of War (POW) and Displaced Persons (DP) camps. Physicians treated trauma in their patients but also experienced trauma themselves; they also wrestled with conflicting feelings toward German civilians and former Nazis....

Physician roles include medical practice both within and outside of their specialties, hospital administration, and work in Prisoner of War (POW) and Displaced Persons (DP) camps. Physicians treated trauma in their patients but also experienced trauma themselves; they also wrestled with conflicting feelings toward German civilians and former Nazis. Explored here are altruistic motives of physicians who treated POWs and DPs, as well as a contemporary assessment of the significance of their work.

Deoxo rhodamine spirolactams (DRS) undergo significant fluorescence enhancement when going from their neutral (closed from) to dicationic state (open form). New and existing DRS were synthesized through the reduction of rhodamine spirolactams (RS). The pKa values for the two protonation processes were determined for a set of three DRS, and the overall rates were measured by the stopped-flow method. These compounds exhibited high ring opening rates, up to 104 times as fast as reported RS...

Estradiol (E2) is an ovarian hormone that has a well-characterized anorexigenic effect in female animals that was originally believed to be mediated through the activation of nuclear estrogen receptors (ERs). However, recent studies from our lab and others have shown rapid anorexigenic effects after activation of membrane ERs (mERs), such as mER and G-protein coupled estrogen receptor (GPER). The comparative action of the non-selective ER agonist, estradiol benzoate (EB), and the selective ER...
Show moreEstradiol (E2) is an ovarian hormone that has a well-characterized anorexigenic effect in female animals that was originally believed to be mediated through the activation of nuclear estrogen receptors (ERs). However, recent studies from our lab and others have shown rapid anorexigenic effects after activation of membrane ERs (mERs), such as mER and G-protein coupled estrogen receptor (GPER). The comparative action of the non-selective ER agonist, estradiol benzoate (EB), and the selective ER and GPER agonists PPT and G-1, respectively, is poorly understood. In the current study, we analyzed meal patterns after acute administration of each of these agonists in OVX female Long-Evans rats. Both PPT and G-1 produced rapid decreases in food intake within 2 and 1 h, respectively, with associated decreases in the size of the first meal following drug treatment. It was also determined that EB produces a prolonged anorexigenic effect, suppressing food intake for three days beginning 12 h after drug treatment. Overall, these findings provide additional evidence that activation of mERs alone is sufficient to decrease food intake and that mER agonists produce more rapid but more transient effects than the non-selective ER agonist EB.

Show moreThe cultural mythos of the American dream posits that any individual can elevate their socioeconomic status in the United States through hard work, regardless of their original social station. However, economic mobility in the United States has stagnated over the past several decades, making the American Dream more wishful thinking than reality. This study seeks to measure how deeply held American voters’ beliefs are about the American dream. This is accomplished through a survey instrument which includes a randomized text which supports either an individualistic, structural, or fatalistic explanation of socioeconomic mobility. A strong belief in the American Dream would indicate a preference for individualistic and fatalistic approaches, rather than structural explanations. By making my survey available on a secure online platform, I have taken a quantitative approach to this question, and have reached a large enough sample size that my results can be considered meaningful.

Pre-existing analyses involving Mikhail Bakhtin’s “chronotope”—from the Greek for “time-space”—have dealt with how space-time configurations categorize literature by genre. This means that each genre of literature, generally, has different spatial-temporal frameworks, and therefore, different chronotopes. One of the least studied chronotopes is the idyllic chronotope.

Show morePre-existing analyses involving Mikhail Bakhtin’s “chronotope”—from the Greek for “time-space”—have dealt with how space-time configurations categorize literature by genre. This means that each genre of literature, generally, has different spatial-temporal frameworks, and therefore, different chronotopes. One of the least studied chronotopes is the idyllic chronotope. Based on pastoral imagery and metaphors, the idyllic chronotope is fundamentally ecocritical: however, many ecocritical studies have not analyzed the use of the idyllic chronotope in a specific author. Accordingly, this project utilizes the idyllic chronotope, through an ecocritical lens, to unpack the spatial-temporal frameworks present in Thomas Hardy’s "Jude the Obscure" and "The Mayor of Casterbridge." In creating “The Dorset Chronotope,” a specific type of idyllic chronotope, this paper argues that the county of Dorset, England, the setting of these two novels, is the primary basis for the space and time characteristics in each respective novel. These spatio-temporal configurations establish relationships between Hardy’s characters and the natural environment, but the way that relationship plays out differs between the novels. For "Jude," these chronotopic relationships are inherently concerned with travel and movement; for "Mayor", the chronotopic relationships reveals the interconnected and circular relationship between the present and the past. Ultimately, “The Dorset Chronotope” inspires a new conversation concerning Hardy’s use of space and time and gives insight into Hardy’s perception of humanity interacting with the surrounding world: that is, that Hardy fundamentally believes in a deterministic world.

Show moreCollege enrollment rates into institutions of higher education have increased over the last thirty years for Black high school graduates (Insitute of Education Science, 2011). However, there are many college enrollment factors that influence a student's decision to attend a college or university. This study sought to determine the most influential college enrollment factors that affect the decision of Black undergraduates to enroll at FSU. Specifically, the study analyzed the role that the Center of Academic Retention and Enhancement, a summer bridge program at the Florida State University, plays in the enrollment of Black undergraduate students. A survey questionnaire was developed and distributed to Black undergraduate students at Florida State University that asked questions concerning the importance of various college enrollment factors. The study found that "Financial Aid: Scholarships and Grants" was the most important college enrollment factor. The C.A.R.E Program was also influential in the decision of the majority of C.A.R.E students to attend FSU. Based off of the findings from the survey, it is evident that the C.A.R.E Program is a vital instrument in the recruitment of Black undergraduate students to FSU and to the academic success of those students throughout their college career.

Show moreThe neuropeptide oxytocin (OXT) is most commonly associated with parturition, lactation, and social behavior but also modulates eating behaviors and homeostatic metabolic processes. Existing research relating metabolic disorders to OXT suggest a role for OXT in regulating the physiology of metabolic tissues. The implications of this role are relevant to Prader-Willi Syndrome (PWS), a genetic disorder which includes a deficit of OXT-producing neurons in the paraventricular nucleus of the hypothalamus, obesity, hypotonia, and hyperphagia. The purpose of this study is to assess the presence of oxytocin receptors (OXTR) in the skeletal muscles of neonatal OXTR wildtype and knockout mice and consider genotype-dependent differences in surrounding adipose tissue. Image analysis for OXTR in muscle was performed on archived autoradiographic samples and associated anatomical cresyl violet stains from 20 μm sagittal slices of postnatal day 0 (P0) whole body OXTR wild-type (WT) and OXTR knock-out (KO) mice. Quantification of radioligand binding in regions of interest (forelimb, hindlimb, and masseter muscles) revealed higher OXTR binding in OXTR-KO males than wildtype males across regions while OXTR-WT females demonstrate higher binding across regions than wildtype males. BODIPY lipid staining of neonatal OXTR-WT and OXTR-KO mice suggest density of lipid droplets in adipose tissue above forelimb does not differ between knock-outs and wildtypes. Failed immunofluorescence staining of EGFP-OXTR transgene positive and negative P0 mice fixed with liquid and vapor paraformaldehyde (PFA) prompted investigation of vapor fixation protocol to optimize endogenous fluorescence. Endogenous fluorescence in trigeminal ganglion of OXTR-EGFP transgene positive and negative mice fixed for varying incubation periods was inconclusive and requires further investigation.

Show morePrior studies suggest that individuals may respond inconsistently to different assessments of suicide attempt (SA) history; yet, little is known regarding why inconsistent reporting of SA history may occur. The overarching goal of this study was to examine factors that influence whether individuals consistently respond to different self-report measures designed to assess SA history. Undergraduate students (N = 141) who reported a lifetime history of suicidal ideation completed three different self-report measures of SA history: the (1) Beck Scale for Suicide Ideation (BSS), (2) Suicidal Behaviors Questionnaire—Revised (SBQ-R), and (3) Self-Injurious Thoughts and Behaviors Interview-Short Form (SITBI-SF), as well as indices of clinical severity, personality traits, and impulsivity. All measures were administered in a randomized order to control for potential order effects. Descriptive statistics and one-way ANOVAs were used to test study aims. Of the sample, 75.2% of participants denied an SA history across all three measures, 16.3% reported an SA across all measures (“consistent responders”), and 8.5% responded inconsistently to SA history measures (“inconsistent responders”). One-way ANOVAs did not reveal any statistically significant differences in clinical severity, personality traits, or impulsivity between consistent and inconsistent responders; however, medium effects were observed when comparing consistent and inconsistent responders on levels of conscientiousness, neuroticism/emotional stability, sensation-seeking, and self-reported future likelihood of making an SA. Findings from this study underscore a need for increased efforts to improve SA history assessments and to identify whether personality and clinical characteristics might play a role in inconsistent reporting of SA history among young adults.

Show moreThe circadian system is an endogenous system of oscillators that rhythmically regulate many biological processes. Memory formation is a prominent process influenced by the circadian clock. Learning and memory are vital processes for any organism to make predictions about certain aspects of their environment. Aplysia have been a significant model organism for studying memory and circadian rhythms, as they demonstrate certain behaviors with fluctuation based on the time of day. Aplysia californica is a diurnal species that only sleeps at night, similar to humans, meaning that they would presumably feed during the day. In previous studies, feeding behavior of Aplysia has provided a great model system for investigating consummatory learning, as new learning paradigms that focus on biting activity have emerged to study classical conditioning in Aplysia. However, there has been a lack in research investigating the circadian aspects of consummatory feeding behaviors in Aplysia and whether or not consummatory learning is shaped by circadian oscillators. This study focused on characterizing consummatory feeding behaviors in Aplysia using a behavioral biting assay time course and it was concluded that biting response is regulated by the circadian clock. However, associative paradigms that measure biting response may not be suitable to investigate circadian modulation of learning and memory. Determining how the circadian clock regulates biting activity is valuable to A. californica’s use as a model organism for studying the circadian modulation of learning.

Show moreZika virus (ZIKV) is a mosquito-transmitted positive RNA sense virus that has spread rapidly in the past year, prompting the World Health Organization (WHO), on 1 February 2016, to announce that the association of Zika infection with clusters of microcephaly and other neurological disorders constituted a Public Health Emergency of International Concern1. The state of emergency eventually ended in November of 2016; however, given the global health concern posed by this virus, a large-scale effort to identify drugs for treating ZIKV and combatting its continued spread is of utmost importance. There are currently no drugs or vaccines for the treatment or prevention of ZIKV infection, although at least one vaccine study is scheduled for stage II/IIb clinical trials. This vaccine is currently being developed by the National Institute of Allergy and Infectious Diseases (NIAID), a branch of the National Institutes of Health (NIH). Although this vaccine study is underway, it is still highly advantageous to have small molecule inhibitors because whether or not this vaccination will produce susceptibilities to secondary flavivirus infections is still unknown42. The urgency that this situation provides led us and others to look to test preexisting drugs for efficacy against ZIKV infection. In attempt to close this gap in treatment and prevention we, in collaboration with Dr. Wei Zheng and others at the National Center for Advanced Translational Sciences (NCATS), previously reported a screen of 6,000 compounds for anti-ZIKV activity. In this study, we identified several compounds with sub-micromolar anti-ZIKV activity in a cell-culture based model, including the FDA approved anthelmintic drug Niclosamide. Niclosamide proved to be capable of inhibiting ZIKV replication at ~0.2μM concentrations, in vitro, when added either before or after ZIKV exposure2. In order to pursue additional potential drugs, our collaborative efforts have, in total, screened over 80,000 compounds for anti-ZIKV activity. Of these, we have selected several compounds for characterization, based on multiple factors: initial antiviral activity in a ZIKV viral protein (non-structural protein 1) detection assay, cytotoxicity profiles, and US Food and Drug Administration (FDA) approval status or previous in vivo safety profiles via human clinical trials. Attempts to further characterize the anthelmintic drug Niclosamide as well as efforts to identify several more compounds for antiviral activity were explored in a cell culture based ZIKV model for efficacy against ZIKV infection and drug anti-ZIKV mechanism of action. My results demonstrate the efficacy of these screening techniques, identify potential compounds for anti-ZIKV drug development, and provide preliminary insights on the selected drug mechanisms of action.

A mutation was previously isolated in stxbp1b resulting in rapid degeneration of retinal photoreceptors. I hypothesize that Stx3, a member of the SNARE complex, is also essential for photoreceptor survival. Mutations were induced in stx3 by injecting gRNA targeting exon 2 and mRNA encoding Cas9 into 1-cell stage zebrafish embryos. Embryos and adults were genotyped using PCR and DNA sequencing. Retinal phenotypes were characterized for visual deficits using the optokinetic reflex (OKR). Histological sections were immunolabeled for photoreceptor-specific antigens. Using this approach, I isolated novel alleles of stx3. One allele is predicted to result in a frame shift mutation and premature stop codon. 25% of the offspring from matings between 2 heterozygous carriers of the novel stx3 allele failed to display an OKR. Larvae lacking an OKR were homozygous for the mutation, and immunolabeling revealed photoreceptor degeneration. These data show that the SNARE complex is essential for photoreceptor survival in the developing zebrafish retina. Supported by the NIH and FSU.

Show moreThis thesis analyzes internal perceptions of institutional racism among undergraduate college students. The research examines the degree to which students perceive the issue of institutional racism to be an existing and pressing problem in our society today. The paper explores how students' perceptions of racism may be influenced by their race, gender, and social attitudes. The thesis also analyzes how students' perceptions of racism are mediated by access and exposure to the vast amounts of political information available on social media sites such as Twitter and Facebook. A survey of 110 college students was conducted and both quantitative and qualitative data were collected. Quantitative results suggest that students' awareness of racial inequality and racial discrimination were not influenced by race or gender identity but were influenced by their social attitudes and the nature of their social media use. Qualitative results provide an in-depth analysis of students' personal opinions about racism and suggest an overall awareness of the issue, but nonetheless polarized views.

Examining in-depth the radar loops from the four radar sites in the area to show how the event unfolded. This will also serve as a visual explanation for why certain areas received significantly more rainfall than others.In the end, by showing the overall synoptic setup and radar imagery that caused the heavy rainfall event over our region, the results will serve as an example for future winter flash flood events if they were to occur again.

Show moreSulfite Reductase is an enzyme that catalyzes the six-electron reduction of sulfite to sulfide for assimilation into biological sulfur-containing compounds, like L-cysteine for protein formation. The Sulfite Reductase holoenzyme is composed of eight copies of the flavoprotein (SiRFP, α subunit) and four copies of the hemoprotein (SiRHP, β subunit) to make a 780 kDa metalloenzyme. SiRFP contains two flavin cofactors, FAD and FMN, which shuttle electrons from NADPH onto the metal core of SiRHP. SiRHP uses the electrons from SiRFP in coordination with its two cofactors, siroheme and an Fe4S4 cluster, to reduce sulfite. How these two subunits assemble has not been fully characterized. Recent data shows the N-terminal 80 amino acids of SiRHP are necessary for complex formation, and one region of SiRFP is suspected of being important for complex formation. Site-directed mutagenesis was used to make SiRFP variants in that region to identify which amino acid residues are responsible for facilitating the formation of the holoenzyme. Point mutants were also made in the N-terminal FMN domain to test which amino acids are necessary for SiRFP function. In vivo analysis through complementation assays showed the variants retained the ability to reduce sulfite. Purification was completed using a nickel affinity column and size exclusion to perform analytical size exclusion.

For instance, in the area of signal detection, there exists a need to process mass quantities of data in a short time frame while simultaneously detecting the time at which a change in the process occurs. This has been a daunting task for many analytics professionals. Hawkins et al. (2003) outlined the traditional implementation of control charts for process monitoring. Charts including the cumulative sum and exponentially weighted moving average control chart were introduced as standard methods for identifying and monitoring process shifts. Unfortunately, these methods are limited by the need to estimate parameters, or are limited by simplifying parameters and known error distributions. To confront this challenge, we propose the use of a nonparametric method for process modeling of functional data that incorporates a variety of resampling methods.

In this mixed-methods study, we examined the levels of reflection, use of future-oriented reflection, and changes in the reflective writing of 90 preservice elementary education teachers enrolled in two sections of an early field experience course (one of which received guided observation) at a large university in the United States While the level of reflection in the writing of 35% of the preservice teachers (PTs) increased in complexity over the span of a semester, only 10% of the PTs ever demonstrated the deepest level of reflection in their writing. Future-oriented reflection accounted for 6% of the language in the assignments with a majority of the instances documenting what PTs planned to do in their future classrooms. PTs in the guided observation group demonstrated a significantly higher level of reflection than those in the unguided group. With these findings in mind, we present implications for teacher-education field experiences and future research, such as providing scaffolding for futureoriented reflection.

Abstract Adenosine triphosphate (ATP) is the molecular currency for cells of all living organisms. When its synthesis, through ATP Synthase, is inhibited or “knocked down” cellular metabolic pathways will be compromised and, I hypothesize that, cell competition will result. Cell competition is a method by which tissue integrity and homeostasis is maintained. When neighboring cells differ in cell fitness, the fit cells will outcompete the weakened cells, leading to cell competition, and...
Show moreAbstract Adenosine triphosphate (ATP) is the molecular currency for cells of all living organisms. When its synthesis, through ATP Synthase, is inhibited or “knocked down” cellular metabolic pathways will be compromised and, I hypothesize that, cell competition will result. Cell competition is a method by which tissue integrity and homeostasis is maintained. When neighboring cells differ in cell fitness, the fit cells will outcompete the weakened cells, leading to cell competition, and therefore, tissue homeostasis. In this experiment, I explored the consequences of depriving cells of ATP Synthase. In order to see cell competition, a mosaic condition using the GeneSwitch Gal4 system was created, consisting of wild type and ATP Synthase knockdown cells. Using the Gal80TS System, a control was also set up creating a homogenous condition of only ATP Synthase knock down cells. Cell competition was visualized using DCP-1 (death caspase-1) staining which targets apoptotic cells. Apoptosis was seen in the mosaic condition, where cells of different fitness neighbored one another. No cell competition was seen in the homogenous condition. The intracellular signaling pathways followed during cell competition were then explored, comparing the deprivation of ATP to the deprivation of insulin. tGPH, which fluoresces green under a confocal microscope, was used in order to trace levels of PI3K following ATP Synthase knock down. When cells are deprived of insulin, tGPH localization to the cell membrane decreases substantially. Similar results were seen in this experiment when cells are deprived of ATP. This result leads to the hypothesis that the insulin and ATP intracellular signaling pathways may be similar or connected. These results allow for further research in this field of interest.

Show moreIn many taxa, individuals display discrete variation in both morphology and behavior. Although these “alternative tactics” are relatively common, their maintenance within populations has yet to be adequately explained. A first step in addressing this question is to describe how behavior changes within a population over time. Sailfin mollies (Poecilia latipinna) are a livebearing fish that show extreme variation in mature male size and reproductive behavior. Adult male size is genetically determined but highly variable within populations, and reproductive behavior covaries with genetically-determined size. Large males display courtship behavior, small males use sneaking behavior, and males in the middle of the size distribution exhibit behavioral plasticity that depends on the social context. Large males also mature more slowly than small males, so the size distribution of adult males within a population can vary dramatically over time. To determine if temporal variation and behavioral plasticity could play a role in maintaining these polymorphisms, we asked if individual male behavior covaries with the male body size distribution across seasons within a population. We censused the population and recorded the size of males, females and juveniles monthly from February 2015 to January 2017. A subset of males, from fish censused in June and October 2015-2016, was brought to the lab to assess reproductive behavior towards a receptive female. We found that the male size distribution varied seasonally; males were largest in the fall and winter, and smallest in late spring and summer. Standard length and its interaction with season significantly affected the male rate of courtship displays, but not sneaking behavior or gonoporal nibbles. This result suggests that changes in individual male behavior track the male size distribution within populations, recapitulating a pattern that has been shown across populations.

Show moreDuring the reign of Benito Mussolini (1925–1943), Italian architects reevaluated the purpose and direction that modernism had taken in Italy, reorienting its previous focus on progressive, functional architecture for the masses to include political propaganda for the state. From the Novecento, Rationalist, and Futurist movements, the Regime chose designs that referred back to the stark monumentality of Imperial Rome. This thesis argues that despite such constraints, Italian architects managed to find innovative solutions and novel forms for representing Italian fascist rhetoric, producing a great deal of individual variation within the architectural schools with which they were associated. Support for Mussolini's empire rested on popular mythologizing about the former Roman Empire and the belief among Italians that the nation and its people were destined to revisit its glory. The propagandistic forms designed by Italian architects employed by the state, as I argue, reflect this understanding as to the role of classical heritage in the present and the place of individual innovation. The principal evidence for my claim is the architecture and urban planning associated with the aborted Esposizione universale of 1942 (colloquially known as E42). The state used this suburban network of exhibition halls to display the supremacy of contemporary Italian culture by making reference to classical Roman antiquity and to a lesser extent the monumental forms of the Renaissance. My study investigates the ways in which the architects of E42, in seeking to integrate the masses on a personal level with the political ideology of the state, referenced Roman antiquity and the Renaissance, thereby visualizing connections between Mussolini's empire and the successful authoritative governments of Italy's past. I provide a detailed assessment of E42 and the various architectural schools competing for state sponsorship in order to demonstrate that the production of Italian fascist visual culture was contingent to a greater degree than has previously been acknowledged upon the notion that the state fostered some measure of individualism in artistic design.

Show moreThe Bohemian Charles IV (1316 – 1378) was crowned King of Bohemia in 1347, King of the Romans in 1349, and Holy Roman Emperor in 1355. At the time of his death, he had successfully expanded the borders of the Holy Roman Empire to include the Kingdom of Bohemia, the Kingdom of Burgundy, the Duchy of Pomerania, and he had himself crowned King of Lombardy. The artwork Charles IV commissioned played a major legitimizing role in this imperial expansion. My study investigates the artistic program of Charles IV in relation to his active promotion of religious cults devoted to three carefully selected saints; St. Wenceslas, St. Charlemagne, and St. Sigismund. I argue that the emperor employed a widespread and calculated artistic program to lay the foundations for his dynasty by creating strong visual ties between himself, his heirs, and the aforementioned royal saints while simultaneously promoting local devotion to those saints. In a detailed examination of the Crowned Reliquaries of Charles IV, the Holy Cross Chapel, and the Madonna of John Očko of Vlašim, I will prove the effectiveness of the emperor's expansive artistic campaign in shaping the way he was perceived in contemporary society, despite his contested ascent to the Bohemian and imperial thrones. I argue that the widespread artistic program of Charles IV was ultimately successful because, by the end of his rule, propagandistic themes common to artwork commissioned by the emperor were present in privately commissioned artwork as well.

Show moreDo students’ automatic, gut-level attitudes towards education predict their academic behaviors and performance? In a study of college students (N = 212), we measured students’ automatic education attitudes using an adapted version of the evaluative priming task. We then examined whether these attitudes predicted students’ more deliberative attitudes towards education, their self-reported study habits, and their GPA, as well as whether these associations were moderated by students’ motivations (i.e., achievement motivation) and opportunity (i.e., stress and sleep) to deliberately evaluate their educational experiences positively. We found little support that automatic education attitudes directly predicted academic outcomes or that these associations were moderated by any motivation or opportunity factors. Nevertheless, automatic education attitudes did interact with stress to predict self-reported attitudes towards education, and exploratory analyses demonstrated that automatic education attitudes indirectly predicted study habits through these deliberate attitudes among students experiencing high levels of stress. This work has potential theoretical and practical implications for both researchers and educators.

Show moreBeyond teaching students to sing and play instruments in an ensemble, many community music organizations aim to teach discipline and mold character. One such organization, the Guri Santa Marcelina located in São Paulo, Brazil, provides a social justice-driven music education in which students of all backgrounds and circumstances are afforded the opportunity to study music, something the organization sees as a fundamental right. Employing both music educators and social workers, the Guri Santa Marcelina attends to the needs of the students holistically in and outside of the classroom working with families and the community as a whole. The organization currently has forty-six satellite locations throughout the city of twenty million. In participating in music classes and activities, and interviewing teachers and social workers at the Guri Santa Marcelina, I had the opportunity to learn how their mission plays out in reality. How do the social workers meet the students’ and families’ needs? How are the music teachers educating their students? How do the social workers and music teachers interact and influence one another? Through ethnographic research, I examine the relationship between music education and social justice in the example of the Guri Santa Marcelina, a music education institution, and social project. Contextualizing my interactions and reflections with a review of the literature, I explore the possibility of creating social change through music education.

Show moreAnxiety has been implicated in a number of physiological and cognitive processes in the human body, including those associated with hypervigilance and sensory processing. Similarly, alpha oscillations (8-12 Hz) have been found to play a role in the inhibition and filtering of irrelevant sensory information, particularly in the visual and auditory modalities. Certain psychological conditions, such as anxiety and post-traumatic stress disorder, exhibit aberrations in sensory filtering that appear to be related to decreased levels of alpha activity in the sensory cortical regions. The decreased levels of alpha amplitude in these conditions are thought to reflect deficits in sensory inhibition, resulting in increased hypervigilance and heightened perception of stimuli. Although this has already been established in the visual modality, it is less clear whether the same holds true in the auditory pathways of affected individuals. In this experiment, we set out to investigate the effects of anxiety on auditory sensitivity and perception. Anxiety was manipulated via 5-minute anxiety induction consisting of disturbing images. The anxiety induction led to predicted increases in self-reported levels of anxiety, along with a general increase in perceived intensity of most sounds and a decrease in reported pleasantness. This effect was further shown to depend on the objective valence and intensity of the auditory stimuli. Moreover, baseline ratings of sound intensity and pleasantness were modulated by inter-individual differences in state anxiety and noise sensitivity, with individuals scoring higher on these measures perceiving negatively-valenced sounds as louder. Overall, a complex relationship was demonstrated between anxiety and sensory processing of auditory stimuli.

There were 35 participants from a summer migrant education program ranging in age from fourth to seventh grade. There were three measures of morphological awareness and two measures of vocabulary knowledge that were examined for correlation. The results showed that there was in fact a positive correlation between each of the compared morphological awareness and vocabulary knowledge tasks. These correlations ranged in strength from moderately to strongly correlated. Future research should also focus on the population of English Learners as it is underrepresented however, it should be causal in order to inform clinicians and teachers on the best method in which to aid English Learners.

Show moreThe modern food system, rooted in industrialized agricultural practices and corporate consolidation of the agribusiness sector, has contributed to numerous adverse public health, environmental, and social consequences. With higher education foodservice spending amounting to over $5 billion and leading foodservice industry trends, colleges and universities are uniquely positioned to challenge the power structure of the food system. The Real Food Challenge (RFC) is a national student movement that aims to shift 20% of existing higher education food budgets away from and industrial farms and highly processed food and toward the procurement of local and community based, ecologically sound, fair, and humane food sources, collectively referred to as “real food,” by 2020. This analysis employs a social movements theoretical framework to outline the best practices for igniting and sustaining a student-driven Real Food Movement at Florida State University (FSU), assesses support for the RFC among key stakeholders, and draws on the limitations of the RFC by identifying alternative sustainable food initiatives being implemented at FSU’s peer institutions.

Because their environment is made up of the surrounding sediment, it is understandable that the grain size of that sediment is a very important factor in the lives of these tiny organisms. I have counted and categorized the communities of nematodes and harpacticoid copepods in two ecologically different sites that are ~256m apart. I have quantified the average grain size for both sites, a saltmarsh (182.69 µm) and a seagrass bed (286.66µm), and have attempted to fit it into an ecological framework for the nematode/copepod communities that live there. I found that between these two habitats, both nematode and copepod communities increased with grain size and that despite ecological differences, the ratio of copepods to nematode in the two sites was not significantly different.

Show moreIn classical mathematics, variables usually commute under multiplication. On the other hand, in this thesis we are interested in a setting in which variables do not always commute. Useful for representing this information are right-angled Artin groups (RAAGs).RAAGs are defined using graphs, i.e. sets of vertices and edges, where vertices represent variables and edges represent a commutative relationship between the connected vertices. RAAGs are often used as a tool to convert problems involving complex geometric phenomena into relatively simple algebra, as we can derive useful information directly from the geometric structure of the underlying graph. Bestvina-Brady groups (BBs) are normal subgroups of RAAGs, originally introduced by Bestvina and Brady to create subgroups of RAAGs which have exotic finiteness properties, such as subgroups which are finitely generated but not finitely presented.This thesis is focused on the problem of understanding splittings. Specifically, how to find an explicit description for some ways of decomposing the groups in terms of the geometry of the underlying graph. In this thesis, we review the findings by Groves and Hull for RAAGs and Chang for BBs, including details and full computations. The methodology used in this thesis relies upon three main topics: group theory, graph theory, and group actions on trees. In the last topic, we use Bass-Serre theory as a bridge between the group and graph theory.
