Georgic Rhetoric, Virtue And The Commercialization Of Agriculture In Pennsylvania From 1785 To 1870, Naomi Ulmer

Masters Theses, 2010-2019

This research examines how farmers in Pennsylvania between 1785 and 1870 were persuaded by georgic agrarianism to take social, economic and even moral risks to abandon a semi-subsistence mode of production in favor of commercial production. The georgic rhetoric is derived from Virgil’s poem “The Georgics.” It discusses agriculture and man’s labor in nature. Virgil discusses the relationship between man, nature and his ability, or inability, to control nature to ensure his own survival. Beginning in the late 18^th century, supporters of improved agriculture, mostly wealthy and upper-class gentlemen, tried to persuade common yeomen farmers to produce for the …

The Effect Of An Acute Bout Of Exercise On Postprandial Metabolic Responses In Younger And Older Adults, Hannah Frick

Masters Theses, 2010-2019

Over 370,000 Americans, primarily between the ages of 60 and 79, die annually as a result of cardiovascular disease caused by physical inactivity and a diet that is calorically dense and high in fat. Current findings in young and middle-aged adults suggest that acute exercise with energy expenditure in excess of 500 kcals, may attenuate the deleterious health effects caused by consuming the typical American meal. Purpose:The purpose of this study was to examine the effects of acute exercise and aging on postprandial lipemia (PPL) and postprandial glycemia (PPG). We hypothesized that aerobic exercise performed prior to the consumption …

Intrusion-Tolerant Order-Preserving Encryption, John Huson

Masters Theses, 2010-2019

Traditional encryption schemes such as AES and RSA aim to achieve the highest level of security, often indistinguishable security under the adaptive chosen-ciphertext attack. Ciphertexts generated by such encryption schemes do not leak useful information. As a result, such ciphertexts do not support efficient searchability nor range queries.

Order-preserving encryption is a relatively new encryption paradigm that allows for efficient queries on ciphertexts. In order-preserving encryption, the data-encrypting key is a long-term symmetric key that needs to stay online for insertion, query and deletion operations, making it an attractive target for attacks.

In this thesis, an intrusion-tolerant order-preserving encryption system …

Using An Eye-Tracking Training Paradigm To Teach Responsiveness To Joint Attention, Allison C. Brandmark

Masters Theses, 2010-2019

Joint Attention (JA) is a social interaction in which attention is concurrently managed between an object or event and a social partner. One social partner initiates joint attention (IJA) by directing the attention of the other social partner. In return, the other social partner responds to joint attention (RJA) by following the social cues. A deficit in JA, which is commonly seen in children with Autism Spectrum Disorder, is correlated with delayed language development and lower levels of communication and social skills. Several studies have successfully trained both IJA and RJA using in-person methodologies. With the development of new technology, …

Examining The Effect Of Interstitial Space On Eastern Oysters (Crassostrea Virginica): Applications Of Photogrammetry And Three-Dimensional Modeling, Bailie Lavan

Masters Theses, 2010-2019

Global oyster populations have decreased by as much as 99% in the past century. Oysters are known ecosystem engineers, providing benthic habitat for macrofauna, linking benthic and pelagic food webs, improving water quality, and mitigating shoreline erosion. Restoration efforts are critical in re-establishing native oyster populations. In the Chesapeake Bay, where oyster loss is primarily due to severe over harvest, artificial substrates with geometric shapes are widely used in restoration efforts. However, natural oyster reefs form emergent shapes with a high degree of aggregation and many interstitial spaces (three-dimensional volumetric spaces between oysters within a reef). The lack of interstitial …

The Effects Of Adenosine Antagonists On Vigilant Attention In Sleep Restricted Rats, Morgan Crewe

Masters Theses, 2010-2019

The relation between chronic sleep restriction and performance on the Psychomotor Vigilance Task (PVT) have been well documented in the human literature, with chronic sleep restriction as little as 7 hours per night resulting in significant impairment in sustained attention performance measured via the PVT. Recently, an analogous version of the human PVT has been developed for use with rodent models (rPVT). Recent studies have measured the effects of sleep restriction on rPVT performance, citing similar results found in the human literature. However, few studies to date have directly examined the role of adenosine accumulation during sleep deprivation in producing …

Test Emotions, Value, And Self-Efficacy: A Longitudinal Model Predicting Examinee Effort And Performance On A Low-Stakes Test, Paulius Satkus

Masters Theses, 2010-2019

The validity of scores from low-stakes tests may be compromised by examinee motivation. Expectancy-Value theory (EV) has been used to frame the antecedents of examinee motivation in low-stakes testing contexts. According to EV theory, the perceived value of the test and the expectancy to succeed on the test directly affect examinee effort, which then affects test performance. Cross-sectional research studies in low-stakes testing contexts offer some support of EV theory. Control-Value theory (CV) serves as another theory to understand motivation toward a task. CV theory encompasses the constructs of expectancy and value from EV theory, but incorporates test emotions as …

However, few studies have been conducted within educational environments on technology-related stress and well-being when technology adoption is mandatory. Building off of Jena’s (2015) prior technostress study, this study aims to contribute to and better understand technostress within a Mandatory Adoption Policy Environment (MAPE). This …

The Microcystis Microbiome: Interactions With Heterotrophic Bacteria In The Microcystis Phycosphere, Alexa Hoke

Masters Theses, 2010-2019

Harmful algal blooms are a growing problem globally in both freshwater and marine systems. Cyanobacterial harmful algal blooms (cHABs) can have numerous environmental and economic impacts. cHABs can reduce oxygen levels in the water column, ultimately leading to the death of larger organisms, and reduce light penetration, impacting aquatic vegetation. cHABs can also release toxins into the water and efforts to prevent toxins from entering drinking water can cost cities millions of dollars in added filtration. Microcystis is a freshwater cyanobacterium that is globally distributed. While many of the abiotic factors that can impact bloom formation are known, biotic factors, …

The Credentialed Workforce: Examining Success Rates Across Short-Term Noncredit Training Programs Aligned With Industry Credentials, Rochelle Fisher

Masters Theses, 2010-2019

A new grant program implemented to provide subsidized training costs for students enrolling in short-term noncredit programs aligned with high-demand industry credentials leading to middle-skill jobs was implemented in July 2016. The grant program follows a pay-for-performance model where students are given a two-thirds discount on tuition but required to pay back an additional one-third if they do not successfully complete their short-term noncredit training. An exploratory study was conducted to provide training program completion and credential attainment rates for the overall program and by student demographic groups (age, race, and gender). Results showed little variation among training program completion …

The Effects Of Timbre On Perceptual Grouping In A Melodic Sequence, Thomas Rohaly

Masters Theses, 2010-2019

The current investigation sought to examine the effects of timbre on perceptual grouping in melodic sequences. While past research has shown that timbre shifts influence listeners’ pitch perception on a note-to-note basis (e.g., see Pitt, 2004; Russo & Thompson, 2005, & Creel, Newport, & Aslin, 2004), the current investigation extended this to timbre’s influence on pitch perception in the context of a melodic phrase. In Experiment 1, participants were presented with melodic sequences, made of sawtooth-like waves. Sequences, consisting of 6 tones, were followed by a target tone that had a static, dull, or bright timbre shift through the use …

Increasing Understanding Of Professor’S Adhd Knowledge And Perception Of Adhd And How This Informs Their Behavior Towards Students With Adhd, Rebecca Rosen

Masters Theses, 2010-2019

Attention deficit hyperactivity disorder (ADHD) is a prevalent learning disability experience by 5.3% of students. The behaviors associated with ADHD (hyperactivity, impulsivity, and inattention) can impact a students’ ability to learn and their behavior and relationships in the classroom. Teachers can help to create a supportive or unsupportive learning environment for students with learning disabilities, specifically ADHD. Unfortunately, these needs are not always met for students in college. Previous research has uncovered primary and secondary teacher’s knowledge, perception, and behavior regarding children with ADHD, but little work has focused on college professors. College professors are likely to have significantly less …

Using Constant Time Delay To Coach Caregivers To Teach Their Young Children With Autism The Picture Exchange Communication System Within The Early Intervention Setting, Anna Balfour

Masters Theses, 2010-2019

Both Early Intervention (EI) and Picture Exchange Communication System (PECS) have been proven to be effective with children diagnosed with Autism Spectrum Disorder (ASD). A relationship between functional communication and behavior has also been noted and described. As individuals learn functional communication, challenging behavior decreases. Early intervention commonly uses PECS to teach children, specifically children with ASD, to communicate. Early intervention can come in different forms, ranging from very intensive daily services to weekly or biweekly visits from service providers. While the literature recommends early intervention, much of it is referencing intensive schedules that are not financially realistic or time …

Methods: Eight youth cyclists (15-18 y, VO_2peak = 61.8 ± 7.7 mL·kg^-1·min^-1) performed an exercise/recovery protocol consisting of 2 bouts of exercise, on 3 separate occasions, in a randomly counterbalanced crossover design. The first exercise bout (EX1) consisted of 30 min of constant-load cycling (40-60% W_max), and 60 min of high-intensity intervals (alternating 2 min …

The Private Navy Of The United States: The Effects Of Privateers On The War Of 1812, Anthony Green

Masters Theses, 2010-2019

The declaration of war in June of 1812 brought more questions than it did answers for the United States. Economically, the government was not prepared to fund a war with multiple fronts. To make matters worse, the government’s primary source of income was through import duties, which they expected to decrease drastically as the war progressed. Militaristically, the United States Navy was too small to offer the protection that was needed from Britain, who possessed the world’s strongest navy at the time. Luckily for the United States, Congress in conjunction with President James Madison authorized privately owned ships to participate …

Anti-Crispr Vs. Crispr: The Evolutionary Arms Race Between Microorganisms, Rachael M. St. Jacques

Masters Theses, 2010-2019

CRISPR arrays are a defense mechanism employed by bacteria against viral invaders. Cas proteins do the work in detecting, capturing, and integrating the viral DNA into the CRISPR array (Barrangou et al., 2007). Anti-CRISPR proteins are produced by phages, viruses that infect bacteria, to stop the bacterial host’s CRISPR-Cas complex from interrupting the phage life cycle (Bondy-Denomy, et al., 2015).

SEA-PHAGES is a course-based bacteriophage research network composed of 120 colleges and known at James Madison University as Viral Discovery. JMU uses the unsequenced Streptomyces griseus ATCC10137 as a host for bacteriophage discovery and propagation, and in this study we …

Effects Of A Lag 3 Schedule Of Reinforcement On The Variability Of Tacting In Individuals Who Engage In Vocal Stereotypy, Jessica K. Serrao

Masters Theses, 2010-2019

Individuals with autism spectrum disorder (ASD) or other developmental disabilities may experience rigid or repetitive behaviors, known as stereotypy. Current research determines effective interventions for increasing variability of vocal responding which effectively decrease stereotypic vocal responding. Lag schedules of reinforcement are a common theme among variability of vocal responding research. The purpose of this AB design study was to evaluate the effectiveness of a Lag 3 schedule of reinforcement in the teaching of variability of tacting. Results indicated that both variable and novel responses increased after the implementation of the Lag 3 schedule, but since these results are based off …

Does Acute Preprandial Exercise Modify Postprandial Inflammation After A High Fat Meal In Young And Older Adults?, William Wisseman

Masters Theses, 2010-2019

A single high-fat meal (HFM) can increase systemic inflammation (postprandial inflammation; PPI) and may be attenuated by recent exercise. However, the effect of preprandial exercise on PPI in older adults (OA) is not clear. Purpose: To determine if preprandial exercise attenuates PPI in YA and OA. Methods: 12 YA (23.3±3.9 years n= 5 M/7 F) and 12 OA (67.7±6 years, n= 8 M/4 F) completed two HFM challenges in a randomized order. During HFM alone, participants abstained from exercise 48 hours prior to the HFM session (except for the exercise session) and adhered to a 12 hour overnight …

Reproductive Character Displacement In Calopteryx Aequabilis And C. Maculata: Improving Species Recognition Through The Divergence Of Male Mating Preferences, Melissa Encinias

Masters Theses, 2010-2019

An ongoing evolutionary question is how co-occurring species maintain reproductive barriers when they are morphologically, behaviorally, and ecologically similar. Without geographic isolation, traits involved in species recognition may be under selection to enhance reproductive barriers. Exaggerated trait differences between species in sympatric populations may reflect selection to reduce misdirected mating between species, or reproductive character displacement. While this phenomenon is widely recognized as an important stage in the speciation process, there is little direct evidence of this process in nature. In two North American damselfly species, Calopteryx aequabilis and C. maculata, wing pigmentation is sexually dimorphic and also shows …

Crm Software Interface Use In Mba Program Email Recruitment Messaging, Tracie Esmaili

Masters Theses, 2010-2019

Competition for university applicants has pushed MBA programs to recruit broadly by taking a more marketing focused self-promotional approach. To grow their applicant pool, many turn to customer relationship management (CRM) systems to manage email recruitment campaigns. CRM systems are efficient communication managers that consistently deliver promotional email content to vast online audiences. However, writing and rhetoric scholarship promote the idea that interfaces, such as CRM systems, are more than mere tools; instead, they impact the purpose, content, and form of communications. This study explores a CRM software interface along with the emails generated from such systems. The first part …
