The National Athletic Trainers’ Association (NATA) categorized ten sudden death conditions which are common in athletics and may warrant a medical emergency. Since the coaches may not be cognizant of these common sudden death conditions, they may not be prepared to handle a medical emergency which threatens the life of student athletes. Objective: Determine if West Virginia Secondary School Activities Commission (WVSSAC) coaches are aware and prepared to provide …

The Role Of Sirt1 In Skeletal Muscle Function And Repair Of Older Mice, Matthew John Myers

Graduate Theses, Dissertations, and Problem Reports (ETD)

Human skeletal muscle is a highly metabolic tissue necessary for mobility and coordination. Responsible for approximately one-fifth of the resting human metabolism, skeletal muscle is also an important regulator of metabolites like glucose and contributes to the regulation of body temperature. Although there is a gradual decline in muscle mass associated with aging, a certain percentage of the population suffer from severe muscle mass and strength deterioration, classified as sarcopenia (5-13% for people aged 60-70 years old, 11-50% for those 80 or older). Sarcopenia is linked to increased morbidity and mortality rates in the elderly population, while annual healthcare costs …

The Impact Of Using Selected Art Therapy Approaches On Students Diagnosed On The Autism Spectrum (As) Or With Behavioral Disabilities (Bd) In An Elementary School Art Classroom., Amie Dawn Perriello

Graduate Theses, Dissertations, and Problem Reports (ETD)

Students with autism and behavior disorders frequently have a difficult time communicating with their teachers and peers. Art can serve as a vehicle for communication while supporting strengths and encouraging self-esteem. Yet few art teachers have the specialized training needed to work with students on the spectrum, and we are often times left to our own intuition and devices on how to deal with these students. These students deserve greater individualized education, yet this can present a unique challenge to any classroom art teacher who does not have the training to deal with students who come from these special populations. …

Empirical Studies Related To Open Questions Regarding Geomagnetic Storms, Bruce Patrick Tepke

Graduate Theses, Dissertations, and Problem Reports (ETD)

Earth’s magnetosphere is subject to disturbances, as evidenced by variations of the geomagnetic field in space and on the ground. It is generally understood that most such disturbances are controlled by variations in the solar wind, with interplanetary magnetic field orientations directed southward opposite to Earth’s dipole magnetic axis being most conducive to energy transfers into the magnetosphere, thus resulting in more disturbed intervals. However, the exact functional form for solar wind driving of the magnetosphere has been widely studied, with proposed functional forms varying from the simple half-wave electric rectifier to expressions with a much more complicated dependence upon …

Confirmation Of Data-Driven Reservoir Modeling Using Numerical Reservoir Simulation, Al Hasan Mohamed Al Haifi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Data driven reservoir modeling, also known as Top-Down Model (TDM), is an alternative to the traditional numerical reservoir simulation technique. Data driven reservoir modeling is a new technology that uses artificial intelligence and machine learning to build full-field reservoir models using field measurements (data - facts) instead of mathematical formulations that represent our current understanding of the physics of the fluid flow through porous media. TDM combines all field measurements into a comprehensive reservoir model to predict the production from each well in a field with multiple wells.

There are many opinions, speculations and criticism about not using the physics-based …

Analyzing Satisfiability And Refutability In Selected Constraint Systems, Piotr Jerzy Wojciechowski

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation is concerned with the satisfiability and refutability problems for several constraint systems. We examine both Boolean constraint systems, in which each variable is limited to the values true and false, and polyhedral constraint systems, in which each variable is limited to the set of real numbers R in the case of linear polyhedral systems or the set of integers Z in the case of integer polyhedral systems. An important aspect of our research is that we focus on providing certificates. That is, we provide satisfying assignments or easily checkable proofs of infeasibility depending on whether the instance …

Effects Of Teacher Training In Trial-Based Functional Analysis Via Video Modeling, Mary Haspel

Graduate Theses, Dissertations, and Problem Reports (ETD)

Trial-based functional analysis (TBFA) is an efficient strategy for assessing challenging behavior in the classroom and a necessary step in developing effective functional assessment- based interventions (FABI). However, researchers have identified several barriers limiting the applicability of this practice in schools, including difficulty in (a) training teachers to mastery; (b) assessing whether teachers can implement this practice independently, with fidelity, in natural settings; and (c) determining whether teachers can use functional analysis (FA) to identify functions of problem behavior and develop effective interventions. This study will address these gaps in the literature by using a novel approach for training teachers …

Service Dogs For Veterans With Ptsd: Taxonomy, Work Stress Reduction, And Matching, Lindsay Parenti

Graduate Theses, Dissertations, and Problem Reports (ETD)

Research suggests that many veterans with post-traumatic stress disorder (PTSD) struggle with reintegration (Sayer et al., 2010), but are unlikely to seek help or complete treatment (Schottenbauer et al., 2008). To make matters worse, available treatment options are often time consuming, challenging, and/or associated with negative side effects (Carafano & Hutchinson, 2017). Using animals as a treatment modality for veterans with PTSD is an emerging topic of interest and has shown promise (Owen, et al., 2016; Richie et al., 2016). However, several factors have hindered the advancement of this field. Obstacles include a lack of standard terminology and classification system, …

Predictors And Health Outcomes Of Treatment-Resistant Depression Among Adults With Chronic Non-Cancer Pain Conditions And Major Depressive Disorder, Drishti Shah

Graduate Theses, Dissertations, and Problem Reports (ETD)

Understanding major depressive disorder (MDD) as a comorbidity in patients with chronic non-cancer pain conditions (CNPC) is of importance because of the high prevalence and well documented bi-directional relationship between MDD and pain. Furthermore, presence of CNPC among adults with MDD often reduces benefits of antidepressant therapy, thereby increasing the possibility of treatment resistance. Treatment-resistant depression (TRD) commonly defined as insufficient response to multiple antidepressant trials, often worsens depression and pain symptoms and can amplify the clinical and economic burden among adults with CNPC and MDD. Additionally, long-term opioid therapy (LTOT) may be prescribed at a higher rate to adults …

Three Essays On Applied Semiparametric Methods, Qinling Lu

Graduate Theses, Dissertations, and Problem Reports (ETD)

The first chapter studies a varying coefficient panel data model with different smoothing variables and fixed effects using a two-step estimation approach. The first-step pilot estimator is constructed by ap- approximating the varying coefficients with B-spline functions. The pilot estimator is then used to perform a one-step backfitting to obtain the second-step efficient estimator with kernel local linear estimation. The second-step estimator is efficient in the sense of being equivalent to a procedure knowing the other components of the varying coefficient. The asymptotic properties of both the pilot and efficient estimators are obtained. A Monte Carlo simulation indicates that the …

Sediment Provenance Study Of The Lower Hamilton Group: An Analysis Of The Organic-Rich Facies And Its Depositional History, Luke Patrick Fritz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Currently, insufficient geological models exist to explain the variability and distribution of TOC in the Marcellus Shale, within the Hamilton Group. TOC is one of the several limiting factors for natural gas production within the Marcellus Shale basin. One possible explanation for the low TOC regions is that detrital dilution was variable across the basin, with different sediment sources contributing detritus to low TOC areas, compared to surrounding regions with higher TOC. This hypothesis is tested by analyzing the source composition of inorganic detritus, using elemental and mineralogical proxies, with two cores in the Hamilton Group. The Armstrong #1 core …
