Effects Of Crisis News On Intercultural Tolerance: An International Comparative Study, Anthony Eseke Jan 2018

Effects Of Crisis News On Intercultural Tolerance: An International Comparative Study, Anthony Eseke

International Crisis and Risk Communication Conference

Human beings are “cultural animals who know and see and hear the world through socially constructed filters.” [1]. Fundamental to these filters are identities. Through the frames of identity, people often negotiate the dialectics of the ‘self’ with/against ‘the other’. The media in their reportage of conflicts and crisis produce and reinforce these dialectics. However, to what extent and directions do these reports influence social tolerance in the audience? This study therefore examined the effects of crisis/conflict news on otherness. The study defined otherness as the appraisal attitudes of tolerance, apathy, or intolerance towards other bodies based on identity categories. …

Impact Of Increased Green Turtle Nesting On Loggerhead Fitness, Amanda R. Carmichael Jan 2018

Impact Of Increased Green Turtle Nesting On Loggerhead Fitness, Amanda R. Carmichael

Honors Undergraduate Theses

Marine turtles exhibit strong fidelity to their nesting beaches, making the conservation of nesting beaches important for ensuring successful sea turtle populations. Conservation of these nesting beaches involves understanding how species interact with the environment and each other, and understanding how environmental change and population growth can affect the suitability of the nesting habitat. The Archie Carr National Wildlife Refuge (ACNWR) is unusual in its high density of sea turtle nesting by two species: green (Chelonia mydas) and loggerhead (Caretta caretta) turtles. The ACNWR in Melbourne Beach, Florida was established in 1991 due to the high density of loggerhead nesting, …

Reconstructing The Vocal Capabilities Of Homo Heidelbergensis, A Close Human Ancestor, Austin Blake Stanley Jan 2018

Reconstructing The Vocal Capabilities Of Homo Heidelbergensis, A Close Human Ancestor, Austin Blake Stanley

Honors Undergraduate Theses

The discovery of 5,500 Homo heidelbergensis fossil specimens at the Sima de los Huesos archaeological site in Spain has opened up the opportunity for research to be conducted on the vocal capabilities of this species. Previous research has revealed that the range of vowel sounds an individual can produce, known as the vowel space, is directly affected by the dimensions of the vocal tract. The vowel spaces of two hominins, Homo sapiens and Homo neanderthalensis, have been reconstructed through previous research. However, the vowel space of Homo heidelbergensis has not yet been reconstructed. In this research, I aim to …

Oyster Reef Restoration: Impacts On Infaunal Communities In A Shallow Water Estuary, Katherine P. Harris Jan 2018

Oyster Reef Restoration: Impacts On Infaunal Communities In A Shallow Water Estuary, Katherine P. Harris

Honors Undergraduate Theses

Oyster reefs are important estuarine ecosystems that provide habitat to many species including threatened and endangered wading birds and commercially important fishes and crabs. Infaunal organisms (i.e. small, aquatic animals that burrow in the sediment) are also supported by oyster reef habitats. Infaunal organisms are critical to marine food webs and are consumed by many important species that inhabit coastal estuaries. However, over the past century 85% of shellfish reef habitats have been lost, making restoration of these areas vital. Due to their important role in coastal food webs, infauna is hypothesized to be a strong indicator of habitat productivity …

Investigating The Role Of The Caspase-6 Cleavage Fragment Of Mutant Huntingtin In Huntington Disease Pathogenesis, Jourdan A. Mckinnis Jan 2018

Investigating The Role Of The Caspase-6 Cleavage Fragment Of Mutant Huntingtin In Huntington Disease Pathogenesis, Jourdan A. Mckinnis

Honors Undergraduate Theses

Huntington disease (HD) is a devastating and fatal neurodegenerative disease. At the moment, no disease modifying therapies are available, with only symptomatic treatment offered to alleviate psychiatric and some types of motor deficits. As a result, many people will continue to suffer and die from this disease. Small molecule therapies have failed to provide benefit in HD, necessitating more complex gene therapy approaches and the identification of less traditional therapeutic targets. A previous study demonstrated that preventing cleavage of the huntingtin (HTT) protein, the protein that when mutated causes HD, by caspase 6 (C6) at amino acid 586 prevents the …

Can Nox1 Activity Initiate Parkinson's-Like Pathology In An Enteroendocrine Cell Line?, Evan Adler Jan 2018

Can Nox1 Activity Initiate Parkinson's-Like Pathology In An Enteroendocrine Cell Line?, Evan Adler

Honors Undergraduate Theses

Increased attention has been given to the gut lately in a number of conditions, from maintaining health via the use of probiotics to treating Autism Spectrum Disorder. Parkinson's Disease has a history with the gut starting with the Braak hypothesis, in which eminent researcher Heiko Braak observed that the spread of Parkinson's (PD) seemed to occur along either olfactory or enteric neurons prior to reaching the substantia nigra in the midbrain, where the classical disease symptoms become evident. Though this finding was largely ignored at the time, the possibility of a gut origin for PD has received interest lately as …

Investigating The Role Of The Gut Microbiome In Huntington Disease, Casey G. Hart Jan 2018

Investigating The Role Of The Gut Microbiome In Huntington Disease, Casey G. Hart

Honors Undergraduate Theses

Huntington disease (HD) is an inherited neurodegenerative disease caused by a trinucleotide repeat expansion in the huntingtin (HTT) gene. Metabolic dysfunction is a feature of HD that is recapitulated in HD mouse models. Our lab has shown that circadian feeding rhythms are disrupted in humanized HD mice and restored by suppression of brain HTT. Furthermore, when circadian feeding rhythm is artificially restored, in addition to normalization of metabolic function, liver and striatal HTT is temporarily reduced, demonstrating that HTT is involved in gut-brain feedback. The gut microbiome, which can regulate gut-brain feedback, has been implicated in the pathogenesis …

Development Of A Non-Human Primate Model For Staphylococcus Aureus Nasal Carriage, Amanda Lasseter Jan 2018

Development Of A Non-Human Primate Model For Staphylococcus Aureus Nasal Carriage, Amanda Lasseter

Electronic Theses and Dissertations

Staphylococcus aureus nasal carriage (SANC) is largely asymptomatic, but presents a risk of autoinfection and dissemination to new immunocompromised hosts. SA disease states range from mild cutaneous infections to life-threatening bacteremia. Historically utilized rodent models do not naturally carry SA in the nose, are insufficient in longitudinal SANC experimentation, and lack immune factors that are vital in human clearance of SA. The nasal passages of non-human primates are similar anatomically and histologically, and reproductive mucosal studies have shown similar immune responses to pathogens and human-relevant microbial profiles. Seventeen captive pigtailed macaques (Macaca nemestrina) were found to naturally carry SA in …

The Evolution Of Peristenus (Hymenoptera: Braconidae): Taxonomy, Phylogenetics And Ecological Speciation, Yuanmeng Zhang

Electronic Theses and Dissertations

Parasitoid wasps are ecologically and economically important as biological control agents. However, little is known about the diversity, distribution and biology of most hymenopteran parasitoids due to their small size, morphological conservatism, and complex life styles. The focus of my PhD research was to investigate the evolution and speciation of euphorine braconid wasps, using a combination of multilocus phylogenetics and population genomic techniques combined with traditional taxonomy. The three data chapters of my dissertation are divided into different taxonomic ranks of euphorine braconids, focusing on genera, species, and populations. For chapter 2, I built a multilocus phylogeny of the tribe …

Revisiting The Postclassic Burials At Lamanai, Belize: A Second Look At The Unique Ventrally Placed, Legs Flexed Burials., Victoria Izzo

Electronic Theses and Dissertations

Analysis of unique mortuary patterns is often used to evaluate the social lives of the deceased and also those of the living who placed them there. The Ventrally Placed, Legs Flexed (VPLF) burials at the site of Lamanai in Belize, dating to the Postclassic period (1000 - 1544), have been recorded as a Maya mortuary pattern since the late 1970's. While many researchers have analyzed these skeletal remains, comprehensive and cumulative individual analysis of the VPLF individuals from Lamanai has not been conducted. In this study, I will argue that the VPLF individuals in this study were local to Lamanai, …

Embryonic Stem Cell Derived Exosomes Enhance Cardiac Stem Cell Differentiation Into Heart Cells, Jamillah Hammond Jan 2018

Embryonic Stem Cell Derived Exosomes Enhance Cardiac Stem Cell Differentiation Into Heart Cells, Jamillah Hammond

Electronic Theses and Dissertations

Transplantation of embryonic stem (ES) cells into the ischemic and infarcted heart has proven to repopulate cardiac cell populations, attenuate structural cardiac remodeling, and rescue cardiac function. Unfortunately, the pluripotency of ES cells increases risk of teratoma formation in vivo. Exosomes, smaller in comparison to ES cells, are cell free carriers of miRNA, proteins, and lipids, and do not suggest risk of teratoma formation. Exosomes have been proposed to mediate and attenuate regeneration following myocardial infarction (MI), however, the role of exosomes derived from ES cells (ES-Exo) in activating resident cardiac stem cells (CSCs) to undergo cardiac differentiation is not …

Evolution And Distribution Of Phenotypic Diversity In The Venom Of Mojave Rattlesnakes (Crotalus Scutulatus), Jason Strickland Jan 2018

Evolution And Distribution Of Phenotypic Diversity In The Venom Of Mojave Rattlesnakes (Crotalus Scutulatus), Jason Strickland

Electronic Theses and Dissertations

Intraspecific phenotype diversity allows for local adaption and the ability for species to respond to changing environmental conditions, enhancing survivability. Phenotypic variation could be stochastic, genetically based, and/or the result of different environmental conditions. Mojave Rattlesnakes, Crotalus scutulatus, are known to have high intraspecific venom variation, but the geographic extent of the variation and factors influencing venom evolution are poorly understood. Three primary venom types have been described in this species based on the presence (Type A) or absence (Type B) of a neurotoxic phospholipase A2 called Mojave toxin and an inverse relationship with the presence of snake venom metalloproteinases …

In Situ Treatment Systems For Remediation Of Polychlorinated Biphenyl-Contaminated Building Materials, Adibah Almutairi Jan 2018

In Situ Treatment Systems For Remediation Of Polychlorinated Biphenyl-Contaminated Building Materials, Adibah Almutairi

Electronic Theses and Dissertations

Polychlorinated Biphenyls (PCBs) are a family of synthetic organohalides comprising 209 congeners which were used historically as additives in paint and caulking materials over a span of many years. Even though the production of PCBs in the USA has been banned since the late 1970s, their former prevalence and widespread use means many structures are still coated with PCB-laden paints. In addition, the presence of PCBs in elastic sealants has resulted in transport of PCBs into concrete structures and has caused soil contamination around buildings. PCB-contaminated building materials have become a significant concern for the environment and building occupants due …

Influence Of Chitosan-Alginate Scaffold Stiffness On Bone Marrow Stromal Cell Differentiation, Isabel Arias Ponce Jan 2018

Influence Of Chitosan-Alginate Scaffold Stiffness On Bone Marrow Stromal Cell Differentiation, Isabel Arias Ponce

Electronic Theses and Dissertations

Tissue grafts are the gold standard for replacing large volume tissue defects. Yet, they present several risks, including infection, low functional outcomes, and reduced graft integrity. Tissue engineering (TE) combines cells and biomaterial scaffolds to foster tissue growth and remodeling. Bone marrow stromal cells (BMSCs) have been shown to respond to the stiffness of their microenvironment, resulting in differentiation into different lineages. 3D porous chitosan-alginate (CA) scaffolds have been previously demonstrated for bone TE with osteoblasts and BMSCs; however, only a single scaffold composition (4 wt%) was studied. Three CA scaffold compositions (2, 4, 6 wt% CA) were produced. Scanning …
