Cognitive Function Following Bubble-Contrast Transcranial Doppler For Evaluation Of Right-To-Left Shunt, Erin Elizabeth Krauskopf
Cognitive Function Following Bubble-Contrast Transcranial Doppler For Evaluation Of Right-To-Left Shunt, Erin Elizabeth Krauskopf
Theses and Dissertations
Background: Stroke is a leading cause of significant physical, cognitive, and psychiatric morbidity. One risk factor for stroke is paradoxical embolization through a patent foramen ovale (PFO). In cardiac clinical practice, power M-mode Transcranial Doppler (TCD) evaluation is the gold standard for diagnosis of PFO, or right-to-left cardiac shunt (RLS). Brain micro-embolization due to diagnostic bubble contrast echocardiography may cause neurological symptoms in patients with PFO. However, the neurocognitive effects of TCD have not been studied. Objective: The purpose of this study was to evaluate cognitive outcomes in patients who undergo routine diagnostic bubble contrast TCD. The aims of the …
The Image Of Women In The Interpreted Qur'an: Translations Of Pickthall, Ali, Hilali And Abdel Haleem, Yassmine Muhammad Mahfouz Muhammad
The Image Of Women In The Interpreted Qur'an: Translations Of Pickthall, Ali, Hilali And Abdel Haleem, Yassmine Muhammad Mahfouz Muhammad
Theses and Dissertations
The Image of Women in the Interpreted Qur’ān: Translations of Pickthall, Ali, Hilālī, and Abdel Haleem By Yassmine Muhammad Mahfouz (Under the supervision of Professor Tahia Abdel Nasser, The American University in Cairo). I have intended this work with the premise of shedding light on the rights of women in the Qur’ān through examining its English translations since this topic has undergone much controversy between patriarchal and Islamophobic camps. However, through the examination of the translations, I have touched on how translation cannot only be problematic but also dangerously influential in presenting the sacred text. The main finding was that …
Human Influences On Anuran Distribution Changes In The Southeastern U.S.A., Michelle Diane Luce
Human Influences On Anuran Distribution Changes In The Southeastern U.S.A., Michelle Diane Luce
Theses and Dissertations
As human populations continue to expand and grow, ecosystems and the species that inhabit them face ever-increasing stress. To conserve these ecosystems, scientists use indicator species to try to measure the impact of human-induced pressures on the environment. Anurans are exceptional indicator species because they are often the first vertebrates to respond to the direct and indirect effects of land use by humans. Sparse historical data have made it difficult to map the ‘natural’ distribution of many species and, therefore, to map any changes in distribution range as a result of human expansion. This study sought to address the lack …
The Impact Of Parentification On Depression Moderated By Self-Care: A Multiple Group Analysis By Gender For South Korea And The U.S., Sunnie Giles
Theses and Dissertations
Parentification, the process of role reversal between parent and child, has long-term deleterious consequences. Using 500 men and 501 women, ranging from 18 years to 55 years old, residing in Korea and the U.S., this study examined the relationship of parentification experienced during childhood and depression in adulthood. The moderating impact of gender and self-care was examined in both the Korean and U.S. samples. Multiple-group analysis showed that the relationship between parentification and depression was statistically significant in all groups (U.S., Korean, male, and female), and self-care was negatively linked to depression. However, self-care did not moderate the relationship between …
Where Did You Come From? The Effects Of Culture, Hometown Region, And Gender On The Perception, Endorsement, And Justification Of Aggression, Lindsay Hendricks
Where Did You Come From? The Effects Of Culture, Hometown Region, And Gender On The Perception, Endorsement, And Justification Of Aggression, Lindsay Hendricks
Theses and Dissertations
The purpose of this exploratory study was to examine whether individual factors, including culture, hometown region, and gender, would affect the likelihood of a person perceiving and justifying an aggressive act. Previous literature explored the differences between distinctive cultural subtypes, hometown regions, and gender on the acceptance of expressing aggression. Hypotheses were established to examine the perception, justification, and endorsement of aggression in a northern setting with college-aged participants. Participants were asked to watch clips from six modern American movies. After each clip, participants answered seven questions based on their perceptions. Six univariate Analysis of Variances (ANOVAs) were conducted to …
Improved Computer-Generated Simulation Using Motion Capture Data, Seth A. Brunner
Improved Computer-Generated Simulation Using Motion Capture Data, Seth A. Brunner
Theses and Dissertations
Ever since the first use of crowds in films and videogames there has been an interest in larger, more efficient and more realistic simulations of crowds. Most crowd simulation algorithms are able to satisfy the viewer from a distance but when inspected from close up the flaws in the individual agent's movements become noticeable. One of the bigger challenges faced in crowd simulation is finding a solution that models the actual movement of an individual in a crowd. This paper simulates a more realistic crowd by using individual motion capture data as well as traditional crowd control techniques to reach …

The Status Of Csr In Corporate America: A Content Analysis Of The Organizations With The Top-Performing Csr Programs Within The Fortune 500, Laura C. Thomas
Theses and Dissertations
Corporate social responsibility has become an accepted part of business for organizations of any size. Organizations are not only expected to be profitable and successful, but they are also expected to be responsible global citizens. However, though this has become an accepted part of business, there remain many areas of CSR research that are under researched. This study examined the top 16 CSR programs of organizations headquartered in the United States to better understand what they communicate about their programs, their relationship with both the news media and government entities, which issues they address the most, and where they implement …
Predicting Alcohol Consumption In Adolescent Rhesus Macaques (Macaca Mulatta), Andrea Nichole Sorenson
Predicting Alcohol Consumption In Adolescent Rhesus Macaques (Macaca Mulatta), Andrea Nichole Sorenson
Theses and Dissertations
Numerous studies show that a low level of response to the intoxicating effects of alcohol is considered a risk factor for future alcoholism. However, assessing this sensitivity usually requires administering a controlled dose of alcohol, which has a number of inherent problems. Early observations in our lab suggest that the response to anesthetics that show cross tolerance with alcohol, like ketamine, are blunted in nonhuman primates at risk for high alcohol intake, and may be a viable measure of future alcohol consumption. This study was designed to test potential predictors of future alcohol consumption using the change in ketamine across …
The Efficacy Of Social Communication Intervention On Teacher Report Of Sociability For Children With Language Impairment, Julianne Grover Smith Guerra
The Efficacy Of Social Communication Intervention On Teacher Report Of Sociability For Children With Language Impairment, Julianne Grover Smith Guerra
Theses and Dissertations
Recent research indicates that many children with Language Impairment (LI) have difficulty with social communication skills. This study assessed the impact of a social communication intervention on teacher perceptions of social withdrawal in children who received the treatment. The intervention targeted emotion understanding using the presentation of children's stories, facial picture cards, and journaling. Teacher perception was measured using the three withdrawal subscales of the Teacher Behavior Rating Scale (TBRS): Solitary-Active withdrawal, Solitary-Passive withdrawal, and Reticence. Following treatment all five participants received lower ratings of withdrawn behavior on some of the subscales. Only one participant received a rating indicting increased …
The Challenge Of Happily Ever After: How Once Upon A Time Fanfic Fairy Tales Model Strategies For Ordinary Life Challenges, Christa M. Baxter
The Challenge Of Happily Ever After: How Once Upon A Time Fanfic Fairy Tales Model Strategies For Ordinary Life Challenges, Christa M. Baxter
Theses and Dissertations
Although many feminist fairy-tale scholars have theorized how the tales shape the lives of their readers, few have explicitly examined what readers themselves have to say about how fairy tales impacted their choices and expectation. This article turns to fanfiction written by fans of ABC's Once Upon a Time television series to discover how these fans challenge or reify fairy-tale expectations, particularly in terms of gender. After outlining the brief history of fairy-tale reception studies concerned with gender, the article then turns to a close reading of three OUAT fanfiction retellings of Beauty and the Beast that show the couple …
A Study Of Slipper And Rail Wear Interaction At Low Speed, Greg V. Cavallaro
A Study Of Slipper And Rail Wear Interaction At Low Speed, Greg V. Cavallaro
Theses and Dissertations
The wear research presented in the work consists of results gathered from adapting a FEM based on a Holloman High Speed Test Track (HHSTT) mission executed in January 2008. The FEM consists of a VascoMax slipper sliding on a stationary AISI-1080 steel rail. The slipper is slid along the rail at speeds of 20 m/s and 40 m/s with complementary vertical velocities of -0.079 m/s and -0.059 m/s, respectively. The surface roughness caused by features such as asperities and valleys of the materials, is simulated in this model by five asperities, 1 micron to 5 microns on the rail and …

Traceability Implementation In Organic Farming: Case Study, Chamomile Tea Production, Shaima Abdelfattah Ibrahim
Theses and Dissertations
Implementing a traceability plan in an herbal production plant is a complex task. In this study an attempt to integrate food safety, quality and traceability through the different stages of the organic German Chamomile (Matricaria recutita) production chain was made. First, all the current relevant international laws, regulations and standards regarding traceability, safety and quality, with emphasis on how and why they are necessary for any food production chain, were set forward. Second, physico-chemical and microbiological analyses were run throughout the different processing stages of production, for four different Chamomile batches produced over the same season using the same farming …
Pre -Service School Psychologists' Racial And Weight-Related Biases And The Relationship That Taking Diversity Courses Has On These Biases, Shaerica Jackson
Pre -Service School Psychologists' Racial And Weight-Related Biases And The Relationship That Taking Diversity Courses Has On These Biases, Shaerica Jackson
Theses and Dissertations
Past research has shown that racial and weight-related biases are present in school settings and can have a negative impact on students. The purpose of this study was to assess the impact of racial and weight-related biases upon judgments that school psychology graduate students make about Black and overweight students who were having problems in school. The problematic behaviors exhibited by the student in the case study were based on symptoms often seen in children with Attention-deficit/Hyperactivity Disorder (ADHD). We also examined the extent to which implicit and/or explicit attitudes moderated the degree of school psychology graduate students' attributions of …
Determining Dictionary And Usage Guide Agreement With Real-World Usage: A Diachronic Corpus Study Of American English, Amanda Kae Fronk
Determining Dictionary And Usage Guide Agreement With Real-World Usage: A Diachronic Corpus Study Of American English, Amanda Kae Fronk
Theses and Dissertations
Dictionaries and, to a lesser extent, usage guides provide writers, editors, and users of American English information on how to use the language appropriately. Dictionaries, in particular, hold authority over correct usage of words. However, historically, usage guides and dictionaries were created using the knowledge of a small group of people. Lexicographers like Noah Webster set out to prescribe a proper way of using American English. To make these judgments, they often relied on a combination of study and idiosyncratic intuitions. A similar process took place in creating usage guides. Though these manuals profess to explain how the language is …
Aggression In Popular Children's Picture Books: A Content Analysis, Karen Dupree Leach
Aggression In Popular Children's Picture Books: A Content Analysis, Karen Dupree Leach
Theses and Dissertations
The purpose of this thesis is to assess children's exposure to aggression through popular children's picture books. Little research has been performed regarding aggression in such books. By analyzing 301 picture books, this study found that the average picture book contained 1.36 aggressive acts, and that aggressive acts were more likely to be included in picture books meant for older children. Verbal aggression was the most widely used type of aggression in children's picture books. There was no significant relationship between the type of character (human or nonhuman) and whether the character acted aggressively. Male characters were more likely to …
Perilous Power: Chastity As Political Power In William Shakespeare's Measure For Measure And Margaret Cavendish's Assaulted And Pursued Chastity, Kelsey Brooke Smith
Perilous Power: Chastity As Political Power In William Shakespeare's Measure For Measure And Margaret Cavendish's Assaulted And Pursued Chastity, Kelsey Brooke Smith
Theses and Dissertations
William Shakespeare and Margaret Cavendish each published plays and poems focusing on the precarious implications and cultural enactments of female chastity in their time. Their lives and writing careers bookend a time when chastity's place in English politics, religion, and social life was perceived as crucial for women while also being challenged and radically redefined. This paper engages in period-specific definitions of virginity and chastity, and with modern scholarship on the same, to explore the historicity of chastity and how representations of self-enforced chastity create opportunities for female political power in certain fiction contexts. Through a comparison of the female …
Error Awareness And Apathy In Moderate-To-Severe Traumatic Brain Injury, Dustin Michael Logan
Error Awareness And Apathy In Moderate-To-Severe Traumatic Brain Injury, Dustin Michael Logan
Theses and Dissertations
Moderate-to-severe traumatic brain injury (M/S TBI) is a growing public health concern with significant impact on the cognitive functioning of survivors. Cognitive control and deficits in awareness have been linked to poor recovery and rehabilitation outcomes. One way to research cognitive control is through awareness of errors using electroencephalogram and event-related potentials (ERPs). Both the error-related negativity and the post-error positivity components of the ERP are linked to error awareness and cognitive control processes. Attentional capacity and levels of apathy influence error awareness in those with M/S TBI. There are strong links between awareness, attention, and apathy. However, limited research …

Expression Of Osteoarthritis Biomarkers In Temporomandibular Joints Of Mice With And Without Receptor For Advanced Glycation End Products (Rage), Elizabeth Murayama Chavez Matias
Theses and Dissertations
This thesis will be organized into three chapters discussing the mechanism underlying the onset and progression of osteoarthritis (OA) in the temporomandibular joint (TMJ). Understanding the mechanism of OA development in the TMJ helps in understanding how OA progresses and how to treat this disease. The goal of this investigation is to examine the process of cartilage degeneration and OA biomarker expression in the TMJ to understand their role in TMJ OA onset and development.Chapter one covers mechanisms that are altered in TMJ OA during disease progression. Using animal models with different stressors such as mechanical disturbances, direct injury, and …
Rapid Adaptation Of Dopamine D2 Receptor Responses In The Brain And Blood Following Acute Ethanol, Ryan J. Folsom
Rapid Adaptation Of Dopamine D2 Receptor Responses In The Brain And Blood Following Acute Ethanol, Ryan J. Folsom
Theses and Dissertations
Dopamine (DA) D2 receptor expression parallels DA levels in the brain and these autoreceptors have been shown to be modulated by long-term ethanol exposure. We have previously demonstrated that ventral tegmental area (VTA) GABA neurons also express D2 autoreceptors (D2R), and that DA and D2R agonists markedly enhance the excitability of VTA GABA neurons, opposite to their well-known auto-receptor inhibition of DA neurons. Most importantly, D2R antagonists block ethanol inhibition of VTA GABA neurons and D2R expression in VTA GABA neurons down-regulates with chronic ethanol, as others have shown for whole VTA D2R expression. The aim of this study was …
Reading Between The Bloodied Lines And Bodies: Dissecting Shakespeare’S Titus Andronicus And Vesalius’S De Humani Corporis Fabrica, Hillary Gamblin
Reading Between The Bloodied Lines And Bodies: Dissecting Shakespeare’S Titus Andronicus And Vesalius’S De Humani Corporis Fabrica, Hillary Gamblin
Theses and Dissertations
Titus Andronicus is infamously Shakespeare’s first, and bloodiest, tragedy, but only a few scholars link this violence with the Renaissance culture of anatomy and dissection. Although scholars mention the anatomical language in Titus Andronicus, their analyses stop short of more fully developing the rich relationship between dissection and Shakespeare’s play. To remedy this oversight, this paper explores the debt that Titus Andronicus owes to contemporary anatomy and dissection culture by comparing Titus Andronicus (est. 1590) with Andreas Vesalius’s revolutionary anatomy textbook, De Humani Corporis Fabrica (1543). Specifically, this paper will identify four major intents of the Fabrica: 1) to display, …
Examination Of Anabolic Signaling And Muscle Growth With Caffeine Treatment In Overloaded Hindlimb Muscle And Electrically Stimulated Muscle Lacking Liver Kinase B1, Timothy Michael Moore
Examination Of Anabolic Signaling And Muscle Growth With Caffeine Treatment In Overloaded Hindlimb Muscle And Electrically Stimulated Muscle Lacking Liver Kinase B1, Timothy Michael Moore
Theses and Dissertations
Skeletal muscle has the ability to increase in size (hypertrophy) after resistance is placed upon it. This hypertrophy is marked by significant upregulation of the mammalian target of rapamycin (mTOR) and its downstream targets. The upstream kinases, protein kinase B (also known as Akt) and AMP-activated protein kinase (AMPK), are two of the many regulators of the mTOR pathway. Recent studies suggest that the widely consumed neuroactive compound caffeine could potentially inhibit mTOR by acting through Akt and/or AMPK. The purpose of this thesis was to: 1) determine if caffeine can inhibit the mTOR pathway and ultimately attenuate skeletal muscle …
Analysis Of Nucleosome Mobility, Fragility, And Recovery: From Embryonic Stem Cells To Invitrosomes, Ashley Nicolle Wright
Analysis Of Nucleosome Mobility, Fragility, And Recovery: From Embryonic Stem Cells To Invitrosomes, Ashley Nicolle Wright
Theses and Dissertations
Several factors direct the placement of specific nucleosomes, which in turn have the ability to regulate DNA accessibility. These factors include, but are not limited to, nucleotide sequence preference, nucleotide modifications, the type of histones present within the nucleosome, and the presence of additional transcription factor or chromatin remodelers. A combination of these and other factors are responsible for tightly controlled efficient transcription within the eukaryotic cell. In order to contribute to the understanding of these complicated processes, three separate hypothesis-driven investigations were carried out. First, we looked into nucleosome positioning and phasing within closely related cells lines. Second, we …
The Supposed Dissipation Of Figural Imagery In Mamluk Art: A Study Of Mamluk Iconography, Jennifer Peruski
The Supposed Dissipation Of Figural Imagery In Mamluk Art: A Study Of Mamluk Iconography, Jennifer Peruski
Theses and Dissertations
The arts of the Mamluks are considered a particularly rich field of study stretching over a nearly three hundred year period. Diverse in their make-up, the progression and development of this art began with strong Ayyubid influences that quickly evolved into a style that was uniquely Mamluk. While many historians have argued that figural imagery all but disappeared in these later progressions of Mamluk art, most notably following the reign of the Mamluk sultan al-Nasir Muhammad (1309-1341), the reality of these conclusions is much more complex. Indeed, the lack of conclusively dated materials from these later periods has been a …
Social Referencing In Domestic Dogs: The Effects Of Human Affective Behavior On Canines Point Following, Peggy Janell Gartman
Social Referencing In Domestic Dogs: The Effects Of Human Affective Behavior On Canines Point Following, Peggy Janell Gartman
Theses and Dissertations
A number of studies have examined the ability of dogs (Canis Familiaris) to follow human given cues. Dogs have been shown to reliably follow pointing cues. To date, few studies have investigated whether emotional cues are a factor in these canine choices. We tested dogs using a two-way object choice food task. Sixty large and medium breed dogs were tested in one of four conditions (positive baited, silent baited, negative non-baited and negative baited). Results showed that dogs reliably followed human pointing cues over emotional cues in three of the four conditions. In the negative non-baited bowl, dogs did not …
Cathy Trask, Monstrosity, And Gender-Based Fears In John Steinbeck’S East Of Eden, Claire Warnick
Cathy Trask, Monstrosity, And Gender-Based Fears In John Steinbeck’S East Of Eden, Claire Warnick
Theses and Dissertations
In recent years, the concept of monstrosity has received renewed attention by literary critics. Much of this criticism has focused on horror texts and other texts that depict supernatural monsters. However, the way that monster theory explores the connection between specific cultures and their monsters illuminates not only our understanding of horror texts, but also our understanding of any significant cultural artwork. Applying monster theory to non-horror texts is a useful and productive way to more fully understand the cultural fears of a society. One text that is particularly fruitful to explore in this context is John Steinbeck’s 1952 novel, …
Noticing Neighbors: Reconsidering Ancient Egyptian Perceptions Of Ethnicity, Taylor Bryanne Woodcock
Noticing Neighbors: Reconsidering Ancient Egyptian Perceptions Of Ethnicity, Taylor Bryanne Woodcock
Theses and Dissertations
Ethnic identities are nuanced, fluid and adaptive. They are a means of categorizing the self and the ‘other’ through the recognition of geographical, cultural, lingual, and physical differences. This work examines recurring associations, epithets and themes in ancient Egyptian texts to reveal how the Egyptians discussed the ethnic uniqueness they perceived of their regional neighbors. It employs Egyptian written records, including temple inscriptions, royal and private correspondence, stelae and tomb autobiographies, and literary tales, from the Old Kingdom to the beginning of the Third Intermediate Period. The textual examples are organized by ethnic group and divided into four regions, beginning …
Polyketide Synthase Iii Isolated From Uncultured Deep-Sea Proteobacterium From The Red Sea- Functional And Evolutionary Characterization, Hadeel Mansour El Bardisy
Polyketide Synthase Iii Isolated From Uncultured Deep-Sea Proteobacterium From The Red Sea- Functional And Evolutionary Characterization, Hadeel Mansour El Bardisy
Theses and Dissertations
Natural polyketide products are one of the major secondary metabolites produced among bacteria, fungi, and plants. They vary from flavonoids, pyrones, and stilbenes to phloroglucinols and resorcinols that are involved in important functions as antimicrobial activity, defense mechanisms and pigmentation. They are biosynthesized from acyl-CoA precursors by polyketides synthases (PKSs) that are categorized into 3 types: I, II and III. PKS type III is considered the simplest in its structure. It was believed that PKS type III was exclusively encoded by higher plants until the enduring efforts of bacterial genomes sequencing revealed the presence of more and more PKSs type …
Identification Of The Critical Cultivation Parameters For Scaling Up The Upstream Process Of Recombinant Human Follicle Stimulating Hormone Production From Chinese Hamster Ovary Cells, Momen Mohsen Amer
Theses and Dissertations
Biotechnology industry has experienced a massive development in the production of recombinant protein therapeutics over the past few decades. Stainless steel bioreactors have been considered the gold standards for the upstream processing for a long time. However, over the past decade, the single use technology has gained a big interest in the field especially with the mammalian and insect cell cultures. The single use based processes offered many advantages over the conventional ones. Disposable systems eliminated the need for cleaning in place (CIP), sterilization in place (SIP) and cleaning validation, reduced the risks of cross contamination, and they also offered …
Towards The Characterization Of A Novel Thermohalophilic Antioxidant Thioredoxin From The Metagenome Of The Red Sea; Lcl Of Atlantis Ii Brine Pool, Mohamed Mohamed Gamal Abdelwahed
Towards The Characterization Of A Novel Thermohalophilic Antioxidant Thioredoxin From The Metagenome Of The Red Sea; Lcl Of Atlantis Ii Brine Pool, Mohamed Mohamed Gamal Abdelwahed
Theses and Dissertations
Due to the crucial antioxidant role of Thioredoxin (Trx) system in various vital cellular processes; DNA synthesis, oxidative stress defense, protein folding, apoptosis and cell growth, this fundamental system is widely expressed in mostly all life's kingdoms. Thus using metagenomic approaches to characterize novel Trx system in unexplored harsh environment will open the window for understanding the evolution of Trx system and its unique adaptation in extreme habitations. One of the unexplored unique ecosystems is the Red Sea's Atalntis II brine pool, specifically, the lower convective layer (LCL). The exceptional harsh conditions of the LCL; anoxic condition, high temperature around …
