Interpreting the information contained in these documents and the ledger book of subscribers for The Southern Musical Advocate and Singer’s Friend magazine through graphs and maps makes the information contained in them easier to access for researchers. The collaboration between a physical museum site, a website, and a Omeka site allow for multiple ways to learn about the history of shape-note music in the Shenandoah …

Links Between Peer Relationships And Social Anxiety Across Adolescence: The Moderating Effects Of Interpersonal Competence, Self-Worth, And Gender, Emily N. Shah

Masters Theses, 2020-current

Links between interpersonal relationships and psychological functioning have been well established in the literature. Specifically, during adolescence, success or distress in peer relationships may have distinct effects on psychological functioning, especially with regard to the development of later social anxiety. The present study aims to examine the ways in which different adolescent peer relationships (i.e., close friendship quality and social acceptance) can predict later social anxiety development. Further, the study considers how different developmental stages of adolescence may impact these relationships, in addition to considering possible conditional effects of interpersonal competence, self-worth, and gender. Early adolescents (age 14) and late …

A Review Of Dietary Monitoring Applications And Eating Disorder/Disordered Eating Symptomatology, Donald Mellott Jr.

Masters Theses, 2020-current

Eating disorders are among the deadliest mental illnesses in the United States. Given their high prevalence and low treatment rates, mitigating risk exposure is necessary for prevention. Dietary monitoring applications are highly popular self-monitoring tools that can inform dietary patterns and improve weight loss efficacy. However, they can also serve as a means for those with body preoccupation to restrict and possibly exacerbate disordered symptomatology. A literature search was conducted to identify research regarding the usage of dietary monitoring applications and eating disorder/disordered eating symptomatology. Twelve articles met inclusion criteria and are discussed in the review. An association between the …

Utilizing creative vignettes and short personal stories, throughout this autoethnographic thesis project I shine light to my lived experiences as a daughter in a Catholic household, diagnosed with chronic illness in adulthood. I use narrative theorizing to understand how the stories I tell in this thesis create meaning in my relationship with my mother. Through personal narratives I explore themes of autonomy and connection within a mother-daughter relationship, illness narratives and illness as a turning point, …

Measuring Referential Communication Dynamically In Older Children With Asd, Caitlin Lee

Masters Theses, 2020-current

Research finds individuals with autism spectrum disorder (ASD) are relatively ineffective and/or inefficient at referential communication. However, this research typically uses static metrics of efficacy (how accurately messages were relayed) and efficiency (overall word count), rather than dynamic ones (e.g., Does the speaker alter subsequent descriptions when the listener previously misunderstood them?). The aim of this research is to use dynamic measures of efficacy and efficiency to examine how speakers with and without ASD adjust their message to meet listener needs across time. Fifteen older children with (n = 8) and without (n = 7) ASD were included. …

Representation In Visual Schedules For Individuals With Disabilities, Colleen Fowkes

Masters Theses, 2020-current

A visual activity schedule (VAS) is an evidence-based intervention that can assist individuals to follow a routine, see what is coming next, reduce dependence on others, and aid in transitions. A VAS is a sequence of visuals (photographs, avatars, line drawings, etc.) that can be used to show the user what they are to do in a specific order. A VAS acts as a template for the task the user is supposed to accomplish. Visual schedules can be beneficial for a wide range of users; they have been seen to be especially effective when used with individuals with disabilities, autism …

An Examination Of Working Memory In Subtle And Mild Cognitive Impairment, Kara Eversole

Masters Theses, 2020-current

Mild cognitive impairment (MCI) is abnormal cognitive decline that may be indicative of an insidious process such as dementia. Individuals with MCI are largely independent in their daily functioning but are at risk of further decline. To more deeply understand the working memory deficits associated with age-related cognitive decline, Lamar and colleagues developed a working memory task with no discontinuation rule: the Backwards Digit Task (BDT). Prior BDT research has demonstrated that individuals with mild cognitive impairment have lower overall scores on this task, and that different subtypes of MCI are more prone to certain errors. Research has not been …

Pilfering Passerines? Inter-Class Competition: A New Direction In Foraging Ecology, Shannon Gillen

Masters Theses, 2020-current

Life in the epigeal layer below leaf litterfall often goes unexplored. Shrews (Soricidae, 1910) have foraged in this microhabitat for millions of years, carving out an existence in harsh habitats around the world, ranging from the tropics to subarctic boreal tundra. Two shrew species that inhabit the Shenandoah Valley of Virginia, the least shrew (Cryptotis parva) and northern short-tailed shrew (Blarina brevicauda), were the focus of this study. Shrews make epigeal foraging trails while they continually forage for food, and caching is a way to save this food for times of low and sporadic food availability. …

The Effects Of Cannabidiol Isolate On Menstrual-Related Symptoms, Morgan L. Ferretti

Masters Theses, 2020-current

The current study aimed to examine the potential effects of CBD isolate for alleviating menstrual-related symptoms (MRS). Participants (N = 33, M_AGE = 20.50, M_BMI = 23.02)were assigned randomly to two open-label dosing groups (160mg, n = 17; 320mg, n = 16) and completed monthly surveys for four months that included MRS-related measures. We examined differences in MRS and related outcomes between baseline and three months of CBD administration. Results revealed reductions in MRS, irritability, anxiety, global impression, stress, and subjective severity scores with a small effect when comparing baseline to all three months of CBD administration. …

The Effects Of A Carbohydrate Hydrogel Beverage On Gastrointestinal Symptoms And Running Performance In Comparison To Conventional Carbohydrate Beverages, Nicholas Minichiello

Masters Theses, 2020-current

PURPOSE: The utilization of hydrogel technology allows carbohydrate beverages to form a gel in the acidic environment of the stomach, potentially enhancing gastric emptying. However, few studies have researched the effects of these beverages on gastrointestinal (GI) tolerance and exercise performance; there is minimal data in a variety of exercise conditions and/or beverage ingestion rates. The purpose of the present study was to assess the effects of a 80 g/h of maltodextrin-fructose hydrogel (MF-H) beverage versus conventional carbohydrate sources on GI symptoms and running performance. METHODS: eight distance runners (26 ± 5 y; VO_2max = 65 ± 7 ml/kg/min) …

Does A Bout Of Acute Resistance Exercise Attenuate The Post-Prandial Lipemic Response To A High Fat Meal In 50-80 Year-Old Adults, Summer Simulcik

Masters Theses, 2020-current

Background: A single high-fat meal (HFM) is known to elevate blood lipid levels above what is normal, resulting in postprandial lipemia (PPL). Chronic hyperlipemia has been associated with increased risk for cardiovascular disease (CVD) and type-2 diabetes mellitus (T2DM) development. Current physical activity (PA) guidelines recommend at least one set of 8-12 repetitions of each exercise to attenuate this risk. Adults older than 50 (OF) years (y) are at an increased risk for cardiometabolic disease compared to younger adults (YA). Aerobic exercise (AE) performed in the pre-prandial period has been observed to attenuate PPL in both OF and YA. However, …

Evaluating The Effectiveness Of Stimulus Presentation Order In Receptive Identification Skills Training, Jazmin Mack

Masters Theses, 2020-current

Receptive identification skills are typically taught using match to sample procedures. This can be done through the process of having a learner match an auditory sample and a visual stimulus from an array of multiple comparison stimuli over several trials. Research has evaluated the effectiveness of various stimuli presentation orders when teaching receptive identification skills with differing recommendations across studies. This thesis aimed to compare the effectiveness of sample first and comparison first presentation orders when teaching receptive identification skills using an adapted alternating treatments design. This study was conducted with two non-verbal early childhood learners. The experimenter tested pictures …

An Analysis Of Behavior Management Strategies Used Within Parent-Child Interaction Therapy To Facilitate Verbalizations By Children With Developmental Disabilities, Megan Barnes

Masters Theses, 2020-current

We examined the effects of the procedures recommended for interventions using the Parent-Child Interaction Therapy (PCIT) protocols on child verbalizations. The effects of the procedures of Child-Directed Interaction (CDI) were examined in a non-concurrent multiple baseline across participants design. Two seven-year-old participants with developmental disabilities and language delay experienced a baseline condition followed by two experimental conditions during a free play environment. A range of child toys were rotated systematically throughout the study. The total number of therapist-child interactions remained consistent across all experimental conditions. The experimenter received bug-in-the-ear feedback about her use of the therapy components in order to …

Masters Theses, 2020-current

This thesis is a performance autoethnography that examines and unpacks my experiences as a Black woman who attends a predominantly white institution. Through narratives, letters, and photos, I reveal and analyze the ways in which I navigate both systems of domination and resistance between my interactions with spaces, people, discourses, and objects. As I use Critical Race Theory, intersectionality, and performance studies as my theoretical underpinnings, I can understand how my Black, female body is situated and contested within the institution that I refer to as Everywhere University. While this project shows my experiences with concepts such as racism, whiteness, …

Urbanization Drives Changes In Avian Communities, Which Are Reflected In The Song Of A Vocal Mimic, Jaclyn Tolchin

Masters Theses, 2020-current

Urban landscapes present problems for wildlife including highly modified habitat, anthropogenic noise pollution, and competition for suitable habitat. These novel selection pressures can filter species present in urban habitats or result in changes to behavior. Recent studies show that some bird species sing differently (louder, higher pitch, faster) in noisier, urban areas compared to quieter, more rural areas, and that anthropogenic noise alone can exclude species. I investigated how the level of urbanization affects 1) bird species composition, and 2) the assemblage of species that a songbird mimics from the local bird community. I studied gray catbirds, Dumetella carolinensis, across …

Masters Theses, 2020-current

Behavior-specific praise (BSP) has been shown to be an effective intervention across age groups for improving behavior in the school setting, including increasing on-task behavior, increasing engaged behavior, and reducing disruptive behavior. Following a review of the literature, the researcher selected tactile prompting paired with a visual prompt to increase specials teachers’ use of BSP. Using a multiple probe across participants design with an add-in component, this study investigated the effects of a visual prompt and a tactile prompt paired with a visual prompt to increase BSP use for two elementary school music teachers. Researchers also examined whether increasing BSP …

Walking The Line: The Legacy Of The Lost Cause In Redefining Femininity At The Normal, 1909-1942, Jennifer D. Page

Masters Theses, 2020-current

The students who attended the State Normal and Industrial School at Harrisonburg during the early period (1909 – 1942) used social organizations to echo, amplify, and rehearse Lost Cause hierarchies of class, gender, and race. The Lee and Lanier Literary Societies were the two elite groups on campus which provided spaces for the women to practice these societal norms. These groups created a system of gatekeeping that ensured exclusivity and elevated the social standing of those who were members. These organizations were spaces to rehearse refinement and to practice the white women’s own roles in society. Their understanding of their …

Identifying Key Stream Restoration Variables In An Agriculturally Impaired Chesapeake Bay Watershed, Julia Portmann

Masters Theses, 2020-current

The Chesapeake Bay watershed spans several states, supports diverse ecosystems, and is crucial to local economies. However, agricultural practices in this region impair water quality. The Smith Creek watershed, within the Shenandoah Valley, was designated a showcase watershed in 2010 by the United States Department of Agriculture to demonstrate the efficacy of implementing restoration projects. We sampled fifteen farms ranging from unrestored to thirty-six years since restoration. At each site, we conducted a kick-net survey for macroinvertebrates, measured canopy cover, algal density, substrate size, and bank height and angle. We identified macroinvertebrates to family and calculated the Chesapeake Basin-wide Index …

Civil Engineering Faculty Publications

In this paper, an analytical method is proposed for the modeling of electromagnetic energy harvesters (EMEH) with planar arrays of permanent magnets. It is shown that the proposed method can accurately simulate the generation of electrical power in an EMEH from the vibration of a bridge subjected to traffic loading. The EMEH consists of two parallel planar arrays of 5 by 5 small cubic permanent magnets (PMs) that are firmly attached to a solid aluminum base plate, and a thick rectangular copper coil that is connected to the base plate through a set of four springs. The coil can move …

The Impact Of High- Vs. Low-Load Resistance Training On Measures Of Muscle Activation, Strength, Body Composition, And Hormonal Markers, Marissa Laina Bello

Theses and Dissertations

Resistance training has shifted towards a high- vs low-load training approach. Heavier loads are suggested to maximally recruit motor units and optimize strength adaptations, whereas lower loads stimulate hypertrophy. However, a majority of the research has not used a true strength range when assessing load. Therefore, the purpose of this investigation was to examine and determine significant differences in strength, body composition, and hormonal markers over nine weeks of high- or low-load resistance training. Secondary purposes of the current investigation were to assess and quantify training load for resistance training using sEMG sensor-embedded compression shorts. 17 recreationally-trained males were randomized …

Department Of Longing, Anthony Gabriel Coffman

Theses and Dissertations

Many have chosen to divide the world of fiction into literary and genre. I do not believe these have to be mutually exclusive. Writers such as Shirley Jackson, Stephen King, and Benjamin Percy note the importance of literary devices while simultaneously creating plots that elicit emotional responses from readers. It is my goal to accomplish the same, and bridge the gap between literary and genre fiction in my collection of short stories by using symbolism and imagery to create a sense of the foreboding.
