Description: Academic stress and the causes of such stress are subjects that are found in very few studies concerning student-athletes. Therefore, the purpose of this quantitative study is to determine how the following variables relate to academic stress and perceived stress either through correlations or differences--demographics, academic classification, major or field of study, athletic scholarship status, and season of sport (in- season/ out of season). An online questionnaire containing a Perceived St… more

Adrenergic and Cholinergic Regulation of Cardiovascular Function in Embryonic Neotropic Cormorants (Phalacrocorax basilianus)

Description: Investigations of cholinergic and adrenergic tone on heart rate (fH) and mean arterial pressure (Pm) during embryonic development have been conducted on numerous avian species. While these investigations have documented that adrenergic tone, a continuous stimulation, on fH and Pm is vital to embryonic development in the birds studied to date, development of cholinergic tone on fH has been shown to vary even within species. Further, past studies have been bias to focus primarily on precocial spe… more

Applied Use of Video Modeling in Educational and Clinical Settings: A Survey of Autism Professionals

Description: Individuals with autism spectrum disorder (ASD) display deficits in communication and social interaction that can impact their ability to function in daily environments. To remediate these deficits, it is critical for professionals to use effective interventions. While there are many evidence-based practices (EBPs) identified for ASD (e.g., video modeling), the adoption of these EBPs may not occur automatically. Existing research suggests professionals have a generally favorable impression o… more

An Argument in Favor of the Saxhorn Basse (French Tuba) in the Modern Symphony Orchestra

Description: The French tuba was a much-needed addition to the brasswind musical instrument family, adding depth, projection and a unique color to French orchestral literature. Its ancestors the serpent and ophicleide both lacked the tonal stability and sonic power to adequately present the bass wind role in a robust orchestra. Through the efforts of its developer and patent-holder Adolphe Sax, the French tuba made converts among players and composers, effectively creating its own niche in music history. Mu… more

Automated GUI Tests Generation for Android Apps Using Q-learning

Description: Mobile applications are growing in popularity and pose new problems in the area of software testing. In particular, mobile applications heavily depend upon user interactions and a dynamically changing environment of system events. In this thesis, we focus on user-driven events and use Q-learning, a reinforcement machine learning algorithm, to generate tests for Android applications under test (AUT). We implement a framework that automates the generation of GUI test cases by using our Q-learning… more

Building an Effective Piano Technique while Avoiding Injury: A Comparison of the Exercises in Alfred Cortot's "Rational Principles of Pianoforte Technique" and Carl Tausig's "Daily Studies for the Pianoforte"

Description: It is the teacher's responsibility to guide students in building an effective and injury-free piano technique. Improper technique, poor training and bad posture at the instrument all may cause problems such as lack of muscle control, weakness, or tension in the hands. Many teachers are interested in finding information about specific exercises dealing with finger strengthening, stretching, and warm-up strategies, as well as guidelines for safe practicing. It is therefore important for both teac… more

Cardiovascular Response to a Behavioral Restraint Challenge: Urge Magnitude Influence in Men and Women

Description: Agtarap, Wright, Mlynski, Hammad, and Blackledge took an initial step in providing support for the predictive validity of a new conceptual analysis concerned with behavioral restraint, defined as active resistance against a behavioral impulse or urge. The current study was designed to partially replicate and extend findings from their study, employing a common film protocol and a procedure for inducing low- and high levels of fatigue. Analyses on key data indicated that the fatigue manipulati… more

Catalytic Properties and Mechanical Behavior of Metallic Glass Powders

Description: Lack of crystalline order and microstructural features such as grain/grain-boundary in metallic glasses results in a suite of remarkable attributes including very high strength, close to theoretical elasticity, high corrosion and wear resistance, and soft magnetic properties. By altering the morphology and tuning of composition, MGs may be transformed into high-performance catalytic materials. In this study, the catalytic properties of metallic glass powders were demonstrated in dissociating to… more

Catastrophe in Permanence: Benjamin's Natural History of Environmental Crisis

Description: Walter Benjamin warned in 1940 of a certain inconspicuous threat to political thinking, not least of all to materialism, that takes progress as an historical norm. Implicit in this conception is what he describes as an empty continuum of time along which the prevailing tradition chronicles its own mythic development and drains everyday life of genuine historical experience. The myth of progressive history advances insidiously today in consumeristic and technocratic attempts at reconciling cultu… more

A Cognitive Radio Application through Opportunistic Spectrum Access

Description: In wireless communication systems, one of the most important resources being focused on all the researchers is spectrum. A cognitive radio (CR) system is one of the efficient ways to access the radio spectrum opportunistically, and efficiently use the available underutilized licensed spectrum. Spectrum utilization can be significantly enhanced by developing more applications with adopting CR technology. CR systems are implemented using a radio technology called software-defined radios (SDR). SD… more
