The Use Of A Visual Motor Test To Identify Lingering Deficits In Concussed Collegiate Athletes, Erik W. Sanders

College of Graduate Studies: Theses & Dissertations

Context: 1.6 to 3.8 million sports-related concussions occur annually. Athletes who have suffered a concussion but are symptom free and have returned to baseline on conventional tests may not necessarily be recovered from the effects of the concussion. The premature return to play of an unrecovered athlete may increase the risk of a subsequent concussion. Measurement of upper-limb visual motor coordination has identified lingering deficits following concussion and so it may provide clinicians with a more sensitive means of tracking recovery. Objective: The purpose of this study was to determine if a visual motor coordination test would identify lingering deficits …

Chaos Theory, Theology, And Curriculum: Striving Towards The Impossibility Of The Gift, Thomas B. Jones

College of Graduate Studies: Theses & Dissertations

It was once thought that small influences could not have a large impact on a grand scale. However, in the 1960s Edward Lorenz discovered that very small disturbances in weather conditions could have a great effect on huge weather systems. With an understanding of chaos theory, which posits that everything matters, I argue that a life based on the lessons of a theology inspired by postmodernism can provide a lens through which to see and act in this chaotic world. By living by this belief, the ability to give the true gift, which is an impossibility and is always to …

Phenotypic Variation In Native North American And Invasive Chinese Populations Of Plantago Virginica, Teresa E. Popp

College of Graduate Studies: Theses & Dissertations

Alien plant species can cause significant economic and biological destruction by invading new environments and outcompeting native species. Through experimental research, the mechanisms by which these species invade can be better understood and applied to their management. Plantago virginica is a perennial herb, native to North America that has recently invaded China. It has been known to reduce crop growth and harbor diseases in the introduced range.

Are Islamist feminists, who are a contemporary phenomenon especially in the Middle East, politically active or inactive? Are liberal or secular women in Egypt more democratic than Islamist women or the opposite? Such questions will be addressed in the following research with emphasis on examining the role of women in Egyptian politics during Ikwhan’s - …

Polymorphic Data Modeling, Steven R. Benson

College of Graduate Studies: Theses & Dissertations

There are currently no data modeling standards for modeling NoSQL document store databases. This work proposes a standard to fill the void. The proposed standard is based on our new data modeling pattern named The Polymorphic Table Pattern. The pattern embraces the “schemaless” nature of document store NoSQL while allowing the data modeler to use his or her existing skillsets. The concepts of our proposed modeling have been demonstrated against MongoDB.

Childhood Trauma, Self-Esteem, And Helping Behaviors: Does History Of Trauma Predict Helping?, Adriana B. Joseph

College of Graduate Studies: Theses & Dissertations

There is insufficient evidence from the available research to fully determine the relationship between self-esteem and helping behaviors. Specifically, some findings indicate that those with lower self-esteem are less likely to help others than those with higher self-esteem (Michelini, Wilson, & Messe, 1975), while others show the opposite trend (Briggs, Landry, & Wood, 2007). Individuals with a history of childhood trauma are more likely to report low self-esteem than those with no history of childhood trauma (Valerio & Lepper, 2009); also, those with a history of trauma are more likely to help others (Frazier, Greer, Gabrielsen, Tennen, Park, & Tomlich, …

Exponentially Weighted Moving Average Charts For Monitoring The Process Generalized Variance, Anna Khamitova

College of Graduate Studies: Theses & Dissertations

The exponentially weighted moving average chart based on the sample generalized variance is studied under the independent multivariate normal model for the vector of quality measurements. The performance of the chart is based on an analysis of the chart's initial and steady-state run length distributions. The three methods that are commonly used to determinate run length distribution, simulation, the integral equation method, and the Markov chain approximation are discussed. The integral equation and Markov chain approaches are analytical methods that require a nu- merical method for determining the probability density and cumulative distribution functions describing the distribution of the sample …

Water Column Ammonium Concentration And Salinity Influence Nitrogen Uptake And Growth Of Spartina Alterniflora, Rachel Mactavish

College of Graduate Studies: Theses & Dissertations

Salt marsh macrophytes, such as Spartina alterniflora, play a critical role in uptake and transformation of inorganic nitrogen before it reaches coastal waters, thereby reducing the potential for eutrophication. Although nitrogen availability typically limits S. alterniflora growth, it may be possible to exceed the nitrogen uptake capacity of S. alterniflora. Increasing either nitrogen concentrations or salinity are key factors regulating S. alterniflora nitrogen uptake. Investigating the effects of nutrients and salinity on S. alterniflora is important given that increases in inorganic nitrogen supply to surface waters from agriculture and urbanization occur simultaneously with freshwater withdrawals that reduce flow and increase …

Success And Failure In Adr: A Dialogue Between Partners, Lela P. Love, Joseph B. Stulberg

Articles

Love and Stulberg critically discuss policy, scholarly, and practice developments in four areas of program development in the area historically referenced as alternative dispute resolution (ADR): the range of process options; the impact of court procedures on ADR program development and practice; the nature of ADR scholarship and training; and the general public's receptiveness to or rejection of the normative principles that structure ADR collaborative processes. Their concluding remarks suggest that the promise of ADR, particularly of the mediation process, remains inspiring to many, even if its effective implementation remains uneven.

To Destroy Or To Preserve: Urban Renewal And The Legal Foundation Of Historic District Zoning, Andrew Tarne

Theses and Dissertations

Historic preservation and urban renewal are often thought to be polar opposites. Where one seeks to preserve, the other generally seeks to destroy in order to rebuild. While the programs appear on the surface to be in opposition, this Thesis seeks to demonstrate that there is a fundamental connection between the underlying legal principles of historic zoning and urban renewal. To that end, the jurisprudence involving historic zoning and aesthetic regulations before and after the seminal urban renewal case of Berman v. Parker has been collected and analyzed. This analysis revealed that courts were hesitant to support aesthetic, and by …
