Quantitative EEG Analysis of Patients with Chronic Pain: An Exploratory Study

Quantitative EEG Analysis of Patients with Chronic Pain: An Exploratory Study

Date: December 2011
Creator: Burroughs, Ramona D.
Description: This study examined quantitative EEGs of six individuals with chronic pain and compared them to an age- and gender-matched normative database of healthy control subjects in an attempt to discern whether a particular pattern of resting state EEG activity is associated with chronic pain. In the chronic pain group, significantly reduced absolute power was seen in delta and theta bandwidths at frontal sites in the eyes-closed condition. In the eyes-open condition, significantly reduced absolute power was seen in delta, theta, and alpha bandwidths at frontal, central, and temporal sites, and increased relative high beta power was seen in the parietal region. Reduced theta/high beta and delta/high beta ratios were seen in the parietal region. Quantitative EEG neuromarkers of chronic pain are suggested.

A Quantitative Modeling Approach to Examining High School, Pre-Admission, Program, Certification and Career Choice Variables in Undergraduate Teacher Preparation Programs

A Quantitative Modeling Approach to Examining High School, Pre-Admission, Program, Certification and Career Choice Variables in Undergraduate Teacher Preparation Programs

Date: December 2007
Creator: Williams, Cynthia Savage
Description: The purpose of this study was to examine if there is an association between effective supervision and communication competence in divisions of student affairs at Christian higher education institutions. The investigation examined chief student affairs officers (CSAOs) and their direct reports at 45 institutions across the United States using the Synergistic Supervision Scale and the Communication Competence Questionnaire. A positive significant association was found between the direct report's evaluation of the CSAO's level of synergistic supervision and the direct report's evaluation of the CSAO's level of communication competence. The findings of this study will advance the supervision and communication competence literature while informing practice for student affairs professionals. This study provides a foundation of research in the context specific field of student affairs where there has been a dearth of literature regarding effective supervision. This study can be used as a platform for future research to further the understanding of characteristics that define effective supervision.

A quantitative study of revenue and expenditures at U.S. community colleges, 1980-2001.

A quantitative study of revenue and expenditures at U.S. community colleges, 1980-2001.

Date: May 2006
Creator: Roessler, Billy Charles
Description: This study provides a detailed description of revenue and expenditure patterns of the United States community college by state and by institutional type (rural-, suburban-serving, and urban-serving) for each five-year period from 1980-81 to 2000-01. The Katsinas, Lacey, and Hardy classification schema for community colleges is used to analyze data from the National Center for Education Statistics' Integrated Postsecondary Educational Data System (IPEDS) and Higher Education General Information Surveys (HEGIS). Further analysis clusters states into the following groupings: states with/without substantial local funding, large "mega-states" versus all other states (employing the methodology developed by Grapevine at Illinois State University), and the structure of state coordination (as developed by Tollefson and others in their studies of state community college systems). The analysis showed wide differences in the various funding patterns for community colleges as related to revenue streams. As late as 1980-91, 16 states contributed 60% or more of the total budgets for their community colleges; by 2000-01, no state did so. By college type, rural-serving community colleges saw the greatest net negative change in their operating budget margins, from 3.2% to 0.4%, although it should be noted that every one of the community college types also experienced a significant decline ...

A Quantitative Study of the Presidential Search Process and Position Longevity in Community Colleges

A Quantitative Study of the Presidential Search Process and Position Longevity in Community Colleges

Date: December 2011
Creator: Howells, Constance L.
Description: A great deal of time, money, and effort can be expended on hiring community college presidents without any assurance that they will remain in their new positions a substantial amount of time. Building on decades of literature reporting the continuing decrease of presidential longevity, this study examined the methods most successful in selecting presidents with relatively greater longevity and what relationship exists between the type of presidential search used and the length of tenure. An original 18-question survey was e-mailed to 904 community college and two-year institution presidents to capture information about both current and previous presidencies. Participants returned 224 valid responses for a response rate of 24.8%. Results of a generalized linear model (GLM) yielded a statistically significant result showing a positive relationship between the variable Q7STDT1(type of presidential searches in current position) and length of tenure of selected candidates (F = 3.41, p = .006).No significant relationship was found between the selection process used in the immediately previous presidential positions and selected candidates’ longevity in those positions. Information from this study can be used to decide what types of selection process should be used and to indicate further topics of inquiry in this area.

Quantization Dimension for Probability Definitions

Quantization Dimension for Probability Definitions

Access: Use of this item is restricted to the UNT Community.
Date: December 2001
Creator: Lindsay, Larry J.
Description: The term quantization refers to the process of estimating a given probability by a discrete probability supported on a finite set. The quantization dimension Dr of a probability is related to the asymptotic rate at which the expected distance (raised to the rth power) to the support of the quantized version of the probability goes to zero as the size of the support is allowed to go to infinity. This assumes that the quantized versions are in some sense ``optimal'' in that the expected distances have been minimized. In this dissertation we give a short history of quantization as well as some basic facts. We develop a generalized framework for the quantization dimension which extends the current theory to include a wider range of probability measures. This framework uses the theory of thermodynamic formalism and the multifractal spectrum. It is shown that at least in certain cases the quantization dimension function D(r)=Dr is a transform of the temperature function b(q), which is already known to be the Legendre transform of the multifractal spectrum f(a). Hence, these ideas are all closely related and it would be expected that progress in one area could lead to new results in another. It would ...

Quantization Of Spin Direction For Solitary Waves in a Uniform Magnetic Field

Quantization Of Spin Direction For Solitary Waves in a Uniform Magnetic Field

Date: May 2003
Creator: Hoq, Qazi Enamul
Description: It is known that there are nonlinear wave equations with localized solitary wave solutions. Some of these solitary waves are stable (with respect to a small perturbation of initial data)and have nonzero spin (nonzero intrinsic angular momentum in the centre of momentum frame). In this paper we consider vector-valued solitary wave solutions to a nonlinear Klein-Gordon equation and investigate the behavior of these spinning solitary waves under the influence of an externally imposed uniform magnetic field. We find that the only stationary spinning solitary wave solutions have spin parallel or antiparallel to the magnetic field direction.

Quantum-Confined CdS Nanoparticles on DNA Templates

Quantum-Confined CdS Nanoparticles on DNA Templates

Date: May 1998
Creator: Rho, Young Gyu
Description: As electronic devices became smaller, interest in quantum-confined semiconductor nanostructures increased. Self-assembled mesoscale semiconductor structures of II-VI nanocrystals are an especially exciting subject because of their controllable band gap and unique photophysical properties. Several preparative methods to synthesize and control the sizes of the individual nanocrystallites and the electronic and optical properties have been intensively studied. Fabrication of patterned nanostructures composed of quantum-confined nanoparticles is the next step toward practical applications. We have developed an innovative method to fabricate diverse nanostructures which relies on the size and a shape of a chosen deoxyribonucleic acid (DNA) template.
