Determining Multidimensional Gender: Development And Psychometrics Of A Measurement Instrument, Karyl Lounsbery

Graduate Theses and Dissertations

Gender identity is often thought of only as a binary construct, masculine and feminine, despite the fact that there are many people who do not see themselves as fitting this dichotomy (Rochman, 2006). Within the counseling field, it is likely that every counselor will eventually see someone who will be struggling with issues of gender identity (Ehrensaft, 2011). The introduction of the Arkansas Multidimensional Gender Scale (AMGS) will show there is a much broader scope of gender identity, more in line with the idea that all gender identities are normal and that there are as many gender identities as there …

The Relationship Between Chronic Ankle Instability And Functional Movement Impairment In Division I Female Athletes, Akihito Tajima

Graduate Theses and Dissertations

Lateral ankle sprains are the most common injury in athletics (Denegar & Miller, 2002; Ekstrand & Tropp, 1990). In addition, the recurrent rate of ankle sprains is as high as 80% (Smith & Reischl, 1986). Repetitive ankle sprains may lead to a phenomenon known as chronic ankle instability (Hertel, 2002). It has been theorized that there are two main attributions to chronic ankle instability: mechanical and functional instability (Monaghan, Delahunt, & Caulfield, 2006). The exact mechanism of chronic ankle instability is still unclear; however, recent studies focus on multiple factors rather than single measurements, in addition to functional testing. A …

Thus, college students across the United States are forming connections with academic advisors during their first few years on campus only to have to repeat the process again with a new advisor. Despite its routine occurrence on college and university campuses across the United States, the issue of mandated advisor …

Foster Parents' Perceptions Of Their Knowledge, Skills, And Abilities In Relation To The Behavioral Challenges Of Foster Youth, Melissa Hall

Graduate Theses and Dissertations

The complex, long-term, and prevalent behavioral problems and needs of foster children and youth continue to be documented (Farmer et al., 2010; United States Department of Health and Human Services [USDHHS], 2005). However, research indicates that foster parents are not adequately prepared or trained to address these challenging behaviors (e.g. Dorsey et al., 2008; Lee & Holland, 1991; Puddy & Jackson, 2003). Foster parent perspectives and the inclusion of their input concerning foster parenting and the behavioral problems of foster youth are needed to examine this crucial problem area (Park & Helton, 2010). The intent of this multi-case study was …

Pitch Perception In Changing Harmony, Cecilia Taher

Graduate Theses and Dissertations

The role of harmony in the definition of tonality provides theoretical framework for the hypothesis that harmonic context affects pitch perception. In tonal music, the stability of individual notes depends on the harmonic setting. It seems then reasonable to expect harmonically guided variations in the cognitive representation of tones. With the purpose of enhancing current models of pitch perception, this thesis proposes an empirical investigation of the effects of harmony on pitch sensitivity. In two experiments, nonmusicians performed a same/different discrimination task on two pitches (a reference tone RT and a comparison tone CT) that were embedded in a melody …

Playing Devil's Advocate: The Attractive Shakespearean Villain, Jonathan Montgomery Green

Graduate Theses and Dissertations

The characters of William Shakespeare have spawned countless words of critical interpretation inspired by the playwright's aptitude for fashioning intricate and conflicted figures. As a master character craftsman, Shakespeare is consistent in creating fascinatingly deep characters, and many of them have even gone so far as to generate entire literary archetypes. From the contemplative Prince Hamlet to the despicable yet charming John Falstaff, Shakespeare's characters remain eternal representatives of what any good character should be: interesting, provocative, and complicated.

However, among the playwright's most hypnotic figures are his villains, those characters whom audiences should by all counts detest but cannot …

A Typology Of Preadolescent Sexual Abusers Based On The Emerging Personality Patterns In The Millon Preadolescent Clinical Inventory, Sam Wallace

Graduate Theses and Dissertations

The purpose of this study was to develop a personality-based typology of preadolescents with sexual behavior problems based the Emerging Personality Patterns in the Millon Preadolescent Clinical Inventory (M-PACI, Millon et al., 2005). Grounding a typology in a theory driven personality system may offer clarity and specificity in understanding preadolescents with sexual behavior problems in a manner that has not yet been explored. A personality and theory driven typology could provide a more comprehensive framework for assessing and treating children who sexually abuse than any of the current taxonomic models.

The study used an ex post facto design with test …

Development Of A Microfluidic Device Coupled To Microdialysis Sampling For The Pre-Concentration Of Cytokines, Randy Francisco Espinal Cabrera

Graduate Theses and Dissertations

A proof-of-concept microfluidic device combined with heparin-immobilized magnetic beads was created to concentrate cytokine proteins collected from microdialysis samples. Cytokines are known to be related to several diseases such as cancer, and Parkinson's diseases, so to be able to develop more effective diseases treatments their interactions have to be well understood. Amine-functionalized polystyrene and carboxyl-functionalized magnetic microspheres of ~6.0 ìm in diameter were used to immobilize heparin. The amount of heparin immobilized on polystyrene beads was 5.82 x 10-8 ± 0.36 x 10-8 M per 1.0 x 106 beads and for magnetic beads was 0.64 x 10-8 ± 0.01 x …

Three-Dimensional Scene Reconstruction Using Multiple Microsoft Kinects, Matt Miller

The Microsoft Kinect represents a leap forward in the form of cheap, consumer friendly, depth sensing cameras. Through the use of the depth information as well as the accompanying RGB camera image, it becomes possible to represent the scene, what the camera sees, as a three-dimensional geometric model. In this thesis, we explore how to obtain useful data from the Kinect, and how to use it for the creation of a three-dimensional geometric model of the scene. We develop and test multiple ways of improving the depth information received from the Kinect, in order to create smoother three-dimensional models. We …

A 1,461-Year Growing Season Precipitation Reconstruction For The Carolina Coastal Plain, Kathryn Perkins Wolff

Graduate Theses and Dissertations

A recollection and dating of ancient cypress trees and subfossil logs was performed at Black River, North Carolina, and the separate Black River, South Carolina. The new updated and expanded chronologies date from AD 365 to 2010 and 549 to 2010, respectively. Baldcypress ring-width chronologies are dominated by high inter-annual to decadal variability and do not tend to capture century scale fluctuations in tree-ring growth that could be associated with centennial scale change in climate. The tree-ring chronologies were standardized with a technique designed to preserve low frequency variance known as regional curve standardization. The two chronologies were averaged into …

Extending The Hybridthread Smp Model For Distributed Memory Systems, Eugene Anthony Cartwright Iii

Graduate Theses and Dissertations

Memory Hierarchy is of growing importance in system design today. As Moore's Law allows system designers to include more processors within their designs, data locality becomes a priority. Traditional multiprocessor systems on chip (MPSoC) experience difficulty scaling as the quantity of processors increases. This challenge is common behavior of memory accesses in a shared memory environment and causes a decrease in memory bandwidth as processor numbers increase. In order to provide the necessary levels of scalability, the computer architecture community has sought to decentralize memory accesses by distributing memory throughout the system. Distributed memory offers greater bandwidth due to decoupled …

Public Parks And Private Ideologies: Building Nineteenth-Century British National Identity Through Landscape, Laura Swaim Witherington

Graduate Theses and Dissertations

This project examines how nineteenth-century landscape theories shaped national identity and were influenced by it. Predominant is an investigation of how the desire for a more egalitarian class structure underlies the changes in British landscape design from an attachment to classical exclusivity through pastoral tropes to a limited acceptance of middle and working classes within public landscapes that represented patriotic values. Although poetic works inform the study, novel-length fiction and non-fiction prose and periodicals are also a primary source of consideration. Novels demonstrate how fictional geography generates the constructs of national ideology, and although canonical works typically referenced in studu …

Navigation And Accessibility For Persons With Disabilities: An Anthropological Study Using Gis On The University Of Arkansas Campus, Deborah Jean Raiees-Dana
