The Evolutionary Selective Pressures Exerted On A3 Actinobacteriophages, Cheyenne Weeks-Galindo

Masters Theses, 2010-2019

This study identified evolutionary selective pressures within subcluster A3 actinobacteriophages. These phages are able to infect the clinically important genus Mycobacterium. Understanding the selective pressures on genes in these phage genomes is a step toward understanding the adaptations that result from short-term and long-term associations of phages and bacteria that have been co-evolving for perhaps billions of years. In this study 149 phamilies (phage protein families) of homologous gene sequences were analyzed using Datamonkey. Complete data were obtained for 57 phamilies. Of these, eleven phamilies were affected by recombination, three showed evidence of predominantly diversifying selection, and twenty-four have …

The Monroe Doctrine As The Transparent Veil Of Isolation During The League Of Nations Debate, Luther D. Roadcap

Masters Theses, 2010-2019

In June 1919, President Woodrow Wilson returned from Paris after several months of negotiating the Treaty of Versailles to end World War One. At the peace conference, Wilson achieved his goal of establishing the League of Nations. However, he had one more hurdle: convince the Republican Senate to ratify the treaty. This was no easy task as Republicans claimed the treaty nullified the Monroe Doctrine, even though the century-old foreign policy was recognized, by name, in the League of Nations Covenant. Why, then, did opponents of the League of Nations in the United States claim isolation and refuse to ratify …

Detecting Changes In Auditory Events, Rachael B. Peck

Masters Theses, 2010-2019

Change deafness is defined as the failure to detect the source of an above-threshold change in an auditory scene. A new paradigm recently demonstrated the phenomenon under analogous conditions to its visual counterpart, change blindness (Hall, Peck, Gaston, & Dickerson, 2015). This investigation examined the use of the paradigm through two experiments which involved the same four simultaneously presented events. Experiment 1 distributed events across a virtual 120º on the azimuth while the target event oscillated across a 60º space throughout each trial. Listeners were instructed to identify the target as soon as possible. Target rate of change was manipulated …

Drive Toward Freedom: African American: The Story Of Black Automobility In The Fight For Civil Rights, Xavier Macy

Masters Theses, 2010-2019

Looking across the 20^th century, this thesis seeks to understand the relationship African Americans developed between automobility and the fight for civil rights, filling a gap left in the historiography of both the automobile and the Civil Rights Movement. Historians of the automobile have almost exclusively focused their lens on white suburbia and the “autotopias” that Americans created, while historians of the Civil Rights Movement ignored the automobile entirely. This thesis hopes to begin to fill that void by explaining how African Americans exploited the technological system of the automobile to create forms of transportation accessible to African American …

The Sentence Continues: Breaking Silences And Becoming Authors Through The Semicolon Project, Brooke E. Covington

Masters Theses, 2010-2019

Through its many digital platforms, The Semicolon Project, a suicide and self-harm prevention initiative, offers its users a creative means of using writing to heal. As its name suggests, the semicolon is an essential mark for this group—grammatically a semicolon represents a place in the sentence that an author could have ended and for the members of this prevention initiative, the semicolon acts in a similar way. By tattooing or drawing a semicolon on the body, the semicolon bearer embody a sense of authorial agency, positioning herself as author and using the semicolon as a representation of her dedication to …

The Effect Of Run Sprint Interval Training On Diabetic Metabolic Markers In Prediabetic Adults, Kathryn L. Hilovsky

Masters Theses, 2010-2019

Abstract

Purpose: The primary purpose of this study was to compare the effects of an 8-week run-sprint interval training (R-SIT) and continuous moderate-intensity training (MIT) on fasting blood glucose, HbA1c, insulin sensitivity, and β-cell function in sedentary, prediabetic adults. Secondary outcomes of the study included anthropometric, body composition variables, and aerobic capacity.

The Psychological Response To A Low Carbohydrate Ketogenic Diet In Combination With A Six-Week Strength Training Protocol, Matthew T. Thorp

Masters Theses, 2010-2019

The aim of the present study was to determine whether or not long-term adherence to a Low-Carbohydrate Ketogenic Diet (LCKD) combined with a powerlifting strength training protocol could produce a positive psychological response. This six-week randomized control trial consisted of a treatment (LCKD) group (7% carbohydrates, 50% fat and 45% protein) and a control (CON) group (ad libitum). Both groups completed a validated powerlifting training protocol, as well as the Hospital Anxiety and Depression Scale and the Profile of Mood States. Multivariate testing and general linear modeling statistical analyses were used to compare psychological response between groups (p < 0.05) and found that there was a significant decrease in anxiety over the duration of six-weeks among both groups. No other psychological responses, including negative responses, were found to be significant. All participants significantly improved one-repetition max bench press, back squat, and deadlift (p < 0.05). The main findings of this study suggest that some positive psychological responses exist from long-term LCKD adherence, as well as potential increases in strength performance.

Exploring Graduate Student Parent Experiences: How To Better Support And Reduce Attrition In An Underserved Population, Christine R. Leaman

Masters Theses, 2010-2019

Changes in the global economy, employer expectations, and cultural norms are causing a shift in the demographics of post-baccalaureate students. Out of necessity to support oneself in an increasingly demanding job market, female graduate student enrollment has been on the rise for a number of years. This, in combination with a general increase in the number of individuals enrolling in graduate degree programs while trying to balance the responsibility of raising children presents a growing problem for institutions of higher education. Graduate student parents are a population that requires additional and varying support services than those of the traditional graduate …

Multicultural and intercultural education are similar terms that share many characteristics but result in different outcomes. Multiculturalism promotes the understanding of diverse cultures, and interculturalism promotes positive communication between diverse cultures. The literature review analyzed similarities and differences between the two pedagogies, and inspired the development of questions for an electronic survey. The survey was disseminated to 926 members of the Virginia Art Education Association to examine the perceptions and uses of multiculturalism in Virginia art classrooms. The survey was also used …

Vanguardia Mujerista Haciendo Escuela: An Oral History Of Cuban Feminism, Marie Eszenyi

Masters Theses, 2010-2019

The high rate of female political participation in Cuba has led many journalists, political scientists, and activists to claim that the country is quite possibly the most feminist in Latin America (Torregrosa, 2012). As the United Nations Entity for Gender Equality (2012) indicates, Cuba ranks third in the world for female participation in legislative bodies. Indeed, Cuba has a long history of female political and revolutionary involvement that positions Cuban feminism both on the forefront and the margins of the economy, governmental institutions, culture, society, military systems, and the workplace during various historical points. Moreover, Cuba’s location just 90 miles …

Using Capture-Mark-Recapture Techniques To Estimate Detection Probabilities & Fidelity Of Expression For The Critically Endangered James Spinymussel (Pleurobema Collina)., Alaina C. Esposito

Masters Theses, 2010-2019

The critically endangered James Spinymussel (Pleurobema collina) is a species of freshwater mussel endemic to Virginia’s James and Dan River basins. In the last 20 years, P. collina has experienced a substantial decline in numbers and currently occupies approximately 10% of its original habitat; however, little information is known about this species to assist in conservation. A 230-meter reach of transitional habitat in Swift Run was selected for repeat observations to estimate detection probabilities using a Capture-Mark-Recapture framework. In June 2014, visual scouting began to locate and tag P. collina (including other mussels in the community) with PIT …

The Effect Of Controlled Burns On Abundance Of Woody Species At Buck Mountain, West Virginia, Barry E. Edgar

Masters Theses, 2010-2019

Each year, the U.S. Forest Service prescribes burns within the George Washington and Jefferson National Forest (GWJNF). Burns are prescribed in the growing (late April-October) and dormant season (November- mid-April). The goal of the burns is to reinstate the natural fire regime, returning forests to their original species composition. Currently in GWJNF, Appalachian pine-oak forests are experiencing an increase in fire-intolerant species, while Quercus species and Gaylussacia brachycera, an endangered shrub species, are declining. In the summer of 2014, a vegetation survey was conducted on Buck Mountain, West Virginia to determine if there was a significant difference between dormant and …

Myside Bias In Probabilistic Ethical Decision Making, Richard E. Hohn

Masters Theses, 2010-2019

This study examined the extent to which myside bias was observed in the context of ethical decision making. In judgment and decision making research the resistance of myside bias is described as a component of rational thinking. Thus, to some effect, this study aimed to examine the extent to which people act rationally when making ethical decisions. Measures of thinking dispositions (actively open-minded thinking and need for cognition) as well as measures of cognitive reflection and probabilistic knowledge were included in the study to examine their associations with myside bias in ethical decisions. Modest myside bias effects were observed between …

The Use Of Differential Reinforcement To Increase Participation/Engagement In Children With Autism In An Inclusion Setting, Kayla Gionti

Masters Theses, 2010-2019

Abstract

Children with autism spectrum disorder (ASD) would gain more from instructional material if they increased their participation and engagement in general education classrooms. However, these children often grow dependent on prompts from teachers and paraprofessionals to participate. This can impede the children from participating independently in other settings and from engaging with the instructional material presented to them. The purpose of this study was to increase independent participation, while decreasing the prompt dependency of 3 children with ASD in a general education classroom. The use of differential reinforcement and prompt fading increased the hand raising behavior of all three …

Predicting Bystander Attitudes Using Rape Myth Acceptance And Adherence To The Commodity Model Of Sex, Kimberly J. Johnson

Masters Theses, 2010-2019

The high rate of sexual assault on college campuses has become a growing concern among college administrators. To combat the prevalence of sexual assault, colleges and universities have begun implementing mandatory bystander intervention training programs, which teach students to look for warning signs indicative of sexual assault and intervene before an assault occurs. Previous research has indicated that an individual’s endorsement of rape myths may play a role in whether or not that individual will intervene in a situation that may lead to sexual assault; however, little research has investigated from where beliefs in rape myths might stem. Sex educators …

Effects Of A Low-Carbohydrate Ketogenic Diet On Power Lifting Performance And Body Composition, Jessica L. Agee

Masters Theses, 2010-2019

This was a six-week randomized controlled trial, with a LCKD intervention group and a normal diet control group (CON). The LCKD group was instructed to consume a diet with less than 7% carbohydrates, 50% fat, and 45% protein. Those in the CON group maintained an ad libitum diet. Both groups completed the same validated training protocol during the intervention. The CON had …

Emergency Cardiac Care In Athletic Training Education, Erica M. Filep

Masters Theses, 2010-2019

In the field of athletic training, preventing sudden cardiac arrest (SCA) has become a vital component of undergraduate athletic training students’ education. Specifically, SCA is the “leading cause of death in young athletes due to a structural cardiac abnormality” (Casa et. al, 2012, p. 15). Numerous studies about sudden death in athletics have been conducted but there is a gap in educational literature. Teaching students how to respond to catastrophic injury or illness is still an area that needs to be expanded upon. Educational competencies and standards have rapidly evolved with each edition of the National Athletic Trainers’ Association (NATA) …

Enhancing Psychology Majors’ Meta-Cognitive Understanding Of Desirable Workplace Skills Using A Short Discussion-Based In-Class Activity, Alena S. Gordienko

Masters Theses, 2010-2019

The skills psychology students possess that employers look for in job applicants include: reliability, integrity, work ethic, communication, technology, critical thinking, teamwork, and professionalism (Rodgers, 2012). I conducted a study to determine whether participating in a brief classroom activity would improve students’ ability to effectively describe their skills. Students were asked to write a cover letter before and after the activity. The activity included a discussion of four skills and student reflection on their experiences that demonstrated these skills. I hypothesized that overall letter-writing would improve, that students’ self-reported levels of preparedness to find a job would improve, that students …

Identity Disclosure In Lesbian, Gay, And Bisexual Patient-Provider Communication, Nicole Hudak

Masters Theses, 2010-2019

Lesbian, gay, and bisexual individuals have encountered barriers in accessing healthcare. Barriers to accessing medical care can stem from discrimination within healthcare, which includes the medicalization of homosexuality. Literature demonstrates that both providers and LGB patients recognize that there are inefficiencies in the current healthcare system for LGB patients. This thesis sought to find how LGB individuals navigated the disclosure of their sexual identities with their providers and what types of communication barriers existed between them. Qualitative, in-depth interviews were conducted with 20 LGB identified participants. The recorded interviews were transcribed and analyzed using a constant comparative method. Four themes …

Inner Sound: Contemporary Abstract Photography In The Wet-Plate Collodion Process, Brian Barger

Masters Theses, 2010-2019

My work is Neo-Romantic in nature. This description implies a rejection of all that is tedious, mundane, and ugly in the modern world, in favor of looking to history, nostalgia, and mystery for inspiration. I intend for the work to be dreamlike and evocative of fantasy, to be poetic rather than prosaic, and to be beautiful rather than purposeful.

To this end, I am investigating abstraction in photography through the use of the wet-plate collodion process. The work is intended to reference spirituality and the subconscious, through the use of the abstraction of nature and natural forms, using the inherent …

Establishing Conditioned Reinforcers In Children With Autism Spectrum Disorder, Kristen Rollman

Masters Theses, 2010-2019

People with Autism Spectrum Disorder (ASD) often demonstrate restricted, repetitive patterns of behaviors, interests, and activities, often involving preoccupations with one or more stereotyped and restricted patterns of interest and an inability to adjust to changes in daily routines and schedules. Academic achievement and skill acquisition present a challenge in children with ASD, often times due to a lack of reinforcer options resulting from these deficits. The current study examines the use of free-operant stimulus preference assessments, progressive-ratio schedule reinforcer analyses, and a Pavlovian conditioning procedure in order to evaluate the establishment of new reinforcers that may be used to …
