Becoming A Mindful Sport Psychology Consultant: Defining, Developing, And Integrating Mindfulness Into Practice, Michelle M. Mcalarnen
Becoming A Mindful Sport Psychology Consultant: Defining, Developing, And Integrating Mindfulness Into Practice, Michelle M. Mcalarnen
Graduate Theses, Dissertations, and Problem Reports (ETD)
Sport psychology consultation is a problem solving situation and process (Sears, Rudisill, & Mason-Sears, 2006) in which sport psychology consultants (SPCs) are interpersonal and content communicators. To date, research in applied sport psychology has not examined consultants from the perspective of consultants as communicators in problem solving situations. Additionally, it remains unclear how consultants' graduate education and applied training experience relates to certain communication skills, such as mindfulness, cognitive flexibility, and communication flexibility. Yet, these skills, and its influence on consultants, have garnered interest for further study in professional practice literature (Baer et al., 2008; Davis, 2013; Poczwardowski & Sherman, …

Heavy Metal Uptake By Four Plant Species: Radish, Indian Mustard, Corn, And Soybean., Oluwasogo Bolaji Alonge
Graduate Theses, Dissertations, and Problem Reports (ETD)
Metal contaminated soils are a problem throughout the world. Because metals accumulate in the food chain they have been linked to adverse human and ecosystem health. One promising approach to remediating metal contaminated soils is phytoremediation but success has been limited by an incomplete understanding of the factors that control metal uptake by plants, including the effects when more than one contaminant metal is present in the system. Metal contaminated soil for this study was collected from near Spelter in Harrison County WV, the site of a former zinc smelting site that has contaminated residential soils and stream sediments with …
Evaluation Of A Practice Change Using Cope (Creating Opportunities For Parent Empowerment) To Address Maternal Anxiety, Depression And Expectations Related To Preterm Birth And Subsequent Neonatal Intensive Care Unit (Nicu) Admission, Dennelle Parker
Graduate Theses, Dissertations, and Problem Reports (ETD)
Background: Nearly half a million premature infants are born in the United States each year. The majority of infants born prematurely are admitted to neonatal intensive care units (NICU) for specialized care. Clinical problems related to parental stress due to preterm birth and NICU admission extend beyond feelings of simple stress by parents to that of helplessness, insufficient knowledge, decreased bonding, depression, and the potential development of Post Partum-Post Traumatic Stress Disorder. Furthermore, these clinical problems can extend to the child. Decreased bonding can cause the child to have clinical and subclinical anxiety disorders; and may further equate to future …
The Role Of Arginase I In Ischemic Stroke And Cardiovascular Disease, Ashley Brooke Petrone
The Role Of Arginase I In Ischemic Stroke And Cardiovascular Disease, Ashley Brooke Petrone
Graduate Theses, Dissertations, and Problem Reports (ETD)
Acute ischemic stroke (AIS) is currently the fifth leading cause of death and a leading cause of long-term disability in the United States. Further, the incidence of AIS is expected to increase dramatically through year 2030. Despite the current and anticipated burden of AIS, treatment options for AIS, both acute and chronic, are extremely limited. Tissue plasminogen activator (tPA) is currently the only FDA-approved drug used to treat AIS; however, only a small fraction of AIS patients are eligible to receive tPA, and of these, only roughly 15 percent benefit from treatment with tPA. Given this, there is a crucial …
Effects Of Size And Size Distribution On The Magnetic Properties Of Maghemite Nanoparticles And Iron-Platinum Core-Shell Nanoparticles, Kelly Pisane
Graduate Theses, Dissertations, and Problem Reports (ETD)
Magnetic nanoparticles with large magnetic moments that can be manipulated with an external magnetic field, have potential uses in medicine because their sizes are comparable to biological scales. For such applications it is important to understand how their magnetic properties are affected by their size and size distribution inherently present in magnetic nanoparticles. For this purpose, maghemite (gamma-Fe2O3) nanoparticles with average diameters of 7.0+/-0.8 nm, 6.3+/-0.6 nm, 3.4+/-0.8 nm and 2.5+/-0.7 nm and Fe-Pt core-shell nanoparticles with an approximate core diameter of 2.2 nm were synthesized and investigated.

The underlying objective is to eliminate the misappropriated energy caused by inter-fracture stress interaction and stress reorientation surrounding the induced fracture network by assessing stress magnitude as a function of operation conditions.;This study is based upon an in-house numerical simulation …
Quantitative Assessment Of The Discrimination Potential Of Class And Randomly Acquired Characteristics For Crime Scene Quality Shoeprints, Nicole Richetelli
Quantitative Assessment Of The Discrimination Potential Of Class And Randomly Acquired Characteristics For Crime Scene Quality Shoeprints, Nicole Richetelli
Graduate Theses, Dissertations, and Problem Reports (ETD)
Footwear evidence has tremendous forensic value; it can focus a criminal investigation, link suspects to scenes, help reconstruct a series of events, or otherwise provide information vital to the successful resolution of a case. When considering the specific utility of a linkage, the strength of the connection between the source footwear and an impression left at the scene of a crime varies with the known rarity of the shoeprint itself, which is a function of the class characteristics, as well as the complexity, clarity, and quality of randomly acquired characteristics (RACs) available for analysis. To help elucidate the discrimination potential …

Use Of Wireless, Ad-Hoc Networks For Proximity Warning And Collision Avoidance In Surface Mines, Venkata Raghava Siva Naga Shashank Sabniveesu
Graduate Theses, Dissertations, and Problem Reports (ETD)
Despite the record of progress achieved in the United States with respect to reducing fatal and non-fatal injuries in surface mines, both the number and severity of these injuries remain unacceptable. A large fraction of these injuries in surface mines are caused by collisions involving large haulage equipment such as trucks, dozers, and front-end loaders. There are two main contributing factors for these collisions: (i) the massive size of these vehicles, which causes several blind spots surrounding the vehicle for the driver, and (ii) the sheer momentum of these vehicles, which makes it hard to maneuver these vehicles and often …
Dimensions Of The Use Of Volunteered Geographic Information In Mass Crisis Events, Xiannian Chen
Dimensions Of The Use Of Volunteered Geographic Information In Mass Crisis Events, Xiannian Chen
Graduate Theses, Dissertations, and Problem Reports (ETD)
Recent studies have suggested that catastrophic events that trigger mass evacuation require surrounding communities to be well-prepared to act as ingress or pass-through areas for potential evacuees; however surrounding rural communities may have insufficient disaster-related logistical resources. In the response phase of disaster management, officials must be able to deploy resources to demand locations in types and quantities based on real-time requirements. Effective cross-jurisdictional disaster management needs real-time information, which is usually unavailable from official, authoritative sources. Conversely, VGI (volunteered geographic information) has the capability to provide real-time and local information in disaster management. This study investigates the possibility of …
Propagating Precipitation Waves In Hydrogels, Darrell Collison
Propagating Precipitation Waves In Hydrogels, Darrell Collison
Graduate Theses, Dissertations, and Problem Reports (ETD)
In 1896, Raphael E. Liesegang discovered that precipitation reactions may produce striking precipi- tation rings and bands. More than a century later, propagating precipitation waves were discovered in similar reactions. The bands and rings discovered by Liesegang are static, but traveling precipitation waves exhibit complex spatiotemporal dynamics. Traveling waves are widespread and occur in both living and nonliving systems. Examples include calcium waves propagating through Xenopus laevis oocytes, cyclic AMP waves in colonies of Dictyostelium discordium cells, and spiral waves in propagating flames fronts. Recently, traveling waves were identified in a precipitation reaction involving AlCl3 and NaOH. The propagating precipitation …

Clustering By Academic Major At Historically Black Colleges And Universities (Hbcus), Aaron Goodson
Clustering By Academic Major At Historically Black Colleges And Universities (Hbcus), Aaron Goodson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Follow-up studies of clustering by academic major, the dynamic of 25% or more of the student-athletes on a roster pursuing the same academic major, indicate that it still occurs in revenue-generating sports (Fountain & Finley 2009, 2011; Otto, 2012). Clustering challenges the notion that student-athletes have control over their collegiate academic experience and reveals that their educational pursuits may not align with their professional goals or provide a meaningful educational experience (Sharp & Sheilley, 2008). Research on clustering is absent in member institutions of different NCAA divisions, institutions with unique missions and history (such as Historically Black Colleges and Universities …

Polyploidy Affects Growth, Fillet Composition, And Fatty Acid Profile In Two Year Old Rainbow Trout, Oncorhynchus Mykiss, Jeremy Lynn Everson
Polyploidy Affects Growth, Fillet Composition, And Fatty Acid Profile In Two Year Old Rainbow Trout, Oncorhynchus Mykiss, Jeremy Lynn Everson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Gonadal development is a dominant physiological process that alters growth and fat metabolism, thereby reducing fillet quality. Sterile, triploid (3N) female rainbow trout, generated by pressure-induced shock of zygotes 30 minutes after fertilization (3NP), are used to eliminate reduced growth and quality associated with gonadogenesis. However, this method does not produce 100% 3N offspring. Crossing a diploid (2N; fertile) female and a tetraploid (4N; fertile) male produces triploid offspring 100% of the time (3NC; sterile). This method is not widely used in the industry because it requires 4N brood stock. The current study examines growth, fatty acid composition, and fillet …
Design Programs For Highwall Mining Operations, Ming Fan
Design Programs For Highwall Mining Operations, Ming Fan
Graduate Theses, Dissertations, and Problem Reports (ETD)
Highwall mining is a hybrid of surface mining and underground mining methods, and is often the only feasible method to recover the coal reserves in the central Appalachian coalfields due to the steep terrain and the closely spaced multiple thin coal seams. Compared to the mountain-top-removal, contour, auger, and underground mining methods, application of the highwall mining method can reduce the environmental impacts, increase the recovery ratio of coal reserves, and enhance mine safety as well as productivity. Therefore, it is probable that highwall mining will be a dominant method for extracting the high-value coal resources in the Appalachian coalfields. …

The Cold Culture Wars: The Fight For Democratic Education In Post-War New York, Brandon C. Williams
The Cold Culture Wars: The Fight For Democratic Education In Post-War New York, Brandon C. Williams
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation explores how the American public school system has become the primary institution for citizens to project, contest, or affirm their values. Primarily, this revolves around competing ideas of democratic education. After World War II, politicians utilized the schools to propagate American democracy, while citizens viewed education as a means to reconstruct the post-war democratic order. Although most representatives acknowledged the schools needed to guard democracy and stem totalitarian aggression, few agreed on how education should accomplish such a feat. Consequently, "democratic education" deviated from its theoretical moorings and found a newly nationalistic expression in a Cold War era …
External Hyperlinking Practices In Print-Based And Online-Native News Sites, Sarah K. Wisniewski
External Hyperlinking Practices In Print-Based And Online-Native News Sites, Sarah K. Wisniewski
Graduate Theses, Dissertations, and Problem Reports (ETD)
This paper describes the differences in the use of external hyperlinks between print-based and online-native news sites. External hyperlinks are links that direct the user to a page outside the original domain, such as the Huffington Post including a link to Wikipedia. A subcategorization of online-native sites into three distinct waves based on launch dates and corresponding to recent transitions in communications technology is proposed. A quantitative content analysis of hyperlinks embedded in the text of articles from print-based, second-wave, and third-wave news sites in 2005, 2010, and 2014 suggests that print-based and online-native news sites do use external hyperlinks …
