The Perceptions of Psychotherapists-in-Training regarding People who Stutter versus Normally Fluent Speakers

The Perceptions of Psychotherapists-in-Training regarding People who Stutter versus Normally Fluent Speakers

Date: December 2004
Creator: Tomczyk, Daniel A.
Description: It has been shown repeatedly that many people hold personality stereotypes of stutterers. The attitudes of psychotherapists regarding stutterers have never been investigated. The present investigation assessed the degree to which psychotherapists-in-training hold stereotypes of stutterers as compared to normally fluent speakers. Two groups viewed a videotaped vignette of a male. In one, the male interviewee displayed stuttering behaviors. In the other, the same male spoke fluently. Participants then rated the male interviewee on several personality dimensions. Contrary to previous findings, the group viewing the stuttering interviewee rated him no differently than did the group viewing the fluent interviewee. Greater knowledge of stuttering was associated with more positive ratings of the person who stuttered. The clinical and research implications of these findings are then discussed.

Percussion scoring and orchestration in the wind and percussion ensemble literature of Jared Spears and David Gillingham

Percussion scoring and orchestration in the wind and percussion ensemble literature of Jared Spears and David Gillingham

Date: August 2001
Creator: White, Marc M.
Description: While many composers of wind ensemble literature have utilized percussion extensively in their compositions, Jared Spears and David Gillingham are renowned wind ensemble composers who have also written specifically for the percussion ensemble. Within their writing, both have exploited percussion through innovative scorings and their interest in rhythm, timbre, and density. The purpose of this study is to explore the scoring practices (functions of the instruments and combinations) and orchestration techniques (rhythmic and density relationships) of both composers, focusing on the manner and extent to which percussion is employed in their wind and percussion ensemble literature. The criteria for examining each piece and genre were developed to compare and contrast each composer's scoring and orchestration characteristics. To this end, each piece and genre was examined through several scoring categories designed to analyze overall ensemble relationships as well as individual functions of the percussion instruments. These categories were also applied to sections of music, focusing specifically on combinations of instruments and the relationship of ensemble choirs in separate and combined roles. Finally, percussion orchestration was examined with respect to motives, rhythmic underpinnings, metric usage, density relationships, and the significance of these elements to structural unity and form. These comparisons showed that, ...

Performance Analysis of Wireless Networks with QoS Adaptations

Performance Analysis of Wireless Networks with QoS Adaptations

Date: August 2003
Creator: Dash, Trivikram
Description: The explosive demand for multimedia and fast transmission of continuous media on wireless networks means the simultaneous existence of traffic requiring different qualities of service (QoS). In this thesis, several efficient algorithms have been developed which offer several QoS to the end-user. We first look at a request TDMA/CDMA protocol for supporting wireless multimedia traffic, where CDMA is laid over TDMA. Then we look at a hybrid push-pull algorithm for wireless networks, and present a generalized performance analysis of the proposed protocol. Some of the QoS factors considered include customer retrial rates due to user impatience and system timeouts and different levels of priority and weights for mobile hosts. We have also looked at how customer impatience and system timeouts affect the QoS provided by several queuing and scheduling schemes such as FIFO, priority, weighted fair queuing, and the application of the stretch-optimal algorithm to scheduling.

Performance appraisal impact on employee career development and performance: A longitudinal study.

Performance appraisal impact on employee career development and performance: A longitudinal study.

Access: Use of this item is restricted to the UNT Community.
Date: December 2006
Creator: Bhagwat, Tanya A.
Description: The purpose of this study was to determine the effectiveness of the implementation of an internally created performance appraisal system as well as the subjects' overall satisfaction with the implementation. The system was implemented at a major technology consulting firm in the US. The subjects of this study were three levels of employees of the firm. An employee survey conducted annually at the firm included questions relating to the implementation of the performance appraisal system. Eight years of employees' responses to three key questions were analyzed. Employees' perceptions of the appraisal feedback aiding increased performance, their belief about the implementation assisting with their career management, satisfaction with the initiative, and their understanding of the requirements for promotion were captured by this survey. Trend analysis indicates that employees at the firm perceived their career path knowledge unimproved, their understanding of promotion criteria unimproved as a result of the implementation. Employees did not indicate overall satisfaction with the implementation and the employee's belief about their skills and abilities utilization did not improve post implementation.

Performance comparison of data distribution management strategies in large-scale distributed simulation.

Performance comparison of data distribution management strategies in large-scale distributed simulation.

Date: May 2004
Creator: Dzermajko, Caron
Description: Data distribution management (DDM) is a High Level Architecture/Run-time Infrastructure (HLA/RTI) service that manages the distribution of state updates and interaction information in large-scale distributed simulations. The key to efficient DDM is to limit and control the volume of data exchanged during the simulation, to relay data to only those hosts requiring the data. This thesis focuses upon different DDM implementations and strategies. This thesis includes analysis of three DDM methods including the fixed grid-based, dynamic grid-based, and region-based methods. Also included is the use of multi-resolution modeling with various DDM strategies and analysis of the performance effects of aggregation/disaggregation with these strategies. Running numerous federation executions, I simulate four different scenarios on a cluster of workstations with a mini-RTI Kit framework and propose a set of benchmarks for a comparison of the DDM schemes. The goals of this work are to determine the most efficient model for applying each DDM scheme, discover the limitations of the scalability of the various DDM methods, evaluate the effects of aggregation/disaggregation on performance and resource usage, and present accepted benchmarks for use in future research.

Performance Evaluation of Data Integrity Mechanisms for Mobile Agents

Performance Evaluation of Data Integrity Mechanisms for Mobile Agents

Access: Use of this item is restricted to the UNT Community.
Date: December 2003
Creator: Gunupudi, Vandana
Description: With the growing popularity of e-commerce applications that use software agents, the protection of mobile agent data has become imperative. To that end, the performance of four methods that protect the data integrity of mobile agents is evaluated. The methods investigated include existing approaches known as the Partial Result Authentication Codes, Hash Chaining, and Set Authentication Code methods, and a technique of our own design, called the Modified Set Authentication Code method, which addresses the limitations of the Set Authentication Code method. The experiments were run using the DADS agent system (developed at the Network Research Laboratory at UNT), for which a Data Integrity Module was designed. The experimental results show that our Modified Set Authentication Code technique performed comparably to the Set Authentication Code method.

Access: Use of this item is restricted to the UNT Community.
Date: December 2002
Creator: Chetty, Sharath
Description: The transmission of voice data over Internet Protocol (IP) networks is rapidly gaining acceptance in the field of networking. The major voice transmissions in the IP networks are involved in Internet telephony, which is also known as IP telephony or Voice Over IP (VoIP). VoIP is undergoing many enhancements to provide the end users with same quality as in the public switched telephone networks (PSTN). These enhancements are mostly required in quality of service (QoS) for the transmission of voice data over the IP networks. As with recent developments in the networking field, various protocols came into market to provide the QoS in IP networks - of them, multi protocol label switching (MPLS) is the most reliable and upcoming protocol for working on QoS. The problem of the thesis is to develop an IP-based virtual network, with end hosts and routers, implement MPLS on the network, and analyze its QoS for voice data transmission.

A Performance Guide and Theorical Study of Keiko Abe's Marimba d'Amore and Prism Rhapsody for Marimba and Orchestra

Date: December 2008
Creator: Àlamo Santos, Juan Manuel
Description: Keiko Abe's contributions to the contemporary marimba repertoire have been a milestone in the development of the marimba as a solo concert instrument. Besides the creation of a new repertoire through commissions and her own compositions, Abe's contributions to the marimba include the improvement of the sound quality of the marimba and the establishment of the five octave instrument as the standard concert marimba. During the last four decades, Abe's compositions have been performed and studied worldwide and become standard literature for the marimba. Abe has written more than sixty compositions for marimba, including concertos, duets and solo pieces. The goal of this dissertation is to provide a comprehensive method for the performance and preparation of two major Keiko Abe's compositions, Marimba d'Amore composed by Abe in 1998 and Prism Rhapsody for Marimba and Orchestra composed in 1996. This dissertation will discuss theoretical as well as performance issues related to these two compositions. Each piece is discussed with regard to its distinctive compositional approach and inherent performances issues. In order to provide the reader an explanation of the compositional procedures used by Abe, specific directions for the performance and preparation of these two works are offered.
