Cognitive and perceptual-motor indicators of lateralized vs. diffuse brain damage in adults.

Cognitive and perceptual-motor indicators of lateralized vs. diffuse brain damage in adults.

Access: Use of this item is restricted to the UNT Community.
Date: December 2002
Creator: Gregory, Erin Kathleen Taylor
Description: Among the goals of the neuropsychological assessment are to detect the presence of brain damage, localize which areas of the brain may be dysfunctional and describe subsequent functional impairments. The sensitivity of neuropsychological instruments in carrying out these functions is a question of some debate. The purpose of this study is to determine the utility of lateralizing indicators from the WAIS-III, McCarron Assessment of Neuromuscular Development (MAND) and Haptic Visual Discrimination Test (HVDT), from the McCarron-Dial System Neuropsychological Assessment Battery (MDS), in ascertaining the presence or absence of brain damage as well as location of lesion. The classification accuracies of using performance level indicators from these tests and lateralizing indicators, alone and together, were compared.

A Common Representation Format for Multimedia Documents

A Common Representation Format for Multimedia Documents

Date: December 2002
Creator: Jeong, Ki Tai
Description: Multimedia documents are composed of multiple file format combinations, such as image and text, image and sound, or image, text and sound. The type of multimedia document determines the form of analysis for knowledge architecture design and retrieval methods. Over the last few decades, theories of text analysis have been proposed and applied effectively. In recent years, theories of image and sound analysis have been proposed to work with text retrieval systems and progressed quickly due in part to rapid progress in computer processing speed. Retrieval of multimedia documents formerly was divided into the categories of image and text, and image and sound. While standard retrieval process begins from text only, methods are developing that allow the retrieval process to be accomplished simultaneously using text and image. Although image processing for feature extraction and text processing for term extractions are well understood, there are no prior methods that can combine these two features into a single data structure. This dissertation will introduce a common representation format for multimedia documents (CRFMD) composed of both images and text. For image and text analysis, two techniques are used: the Lorenz Information Measurement and the Word Code. A new process named Jeong's Transform is ...

Comparative biochemistry and genetic analysis of nucleoside hydrolase in  Escherichia coli,  Pseudomonas aeruginosa, and  Pseudomonas fluorescens.

Comparative biochemistry and genetic analysis of nucleoside hydrolase in Escherichia coli, Pseudomonas aeruginosa, and Pseudomonas fluorescens.

Date: December 2002
Creator: Fields, Christopher J.
Description: The pyrimidine salvage enzyme, nucleoside hydrolase, is catalyzes the irreversible hydrolysis of nucleosides into the free nucleic acid base and D-ribose. Nucleoside hydrolases have varying degrees of specificity towards purine and pyrimidine nucleosides. In E. coli, three genes were found that encode homologues of several known nucleoside hydrolases in protozoa. All three genes (designated yaaF, yeiK, and ybeK) were amplified by PCR and cloned. Two of the gene products (yeiK and ybeK) encode pyrimidine-specific nucleoside hydrolases, while the third (yaaF) encodes a nonspecific nucleoside hydrolase. All three were expressed at low levels and had different modes of regulation. As a comparative analysis, the homologous genes of Pseudomonas aeruginosa and P. fluorescens (designated nuh) were cloned. Both were determined to encode nonspecific nucleoside hydrolases. The nucleoside hydrolases of the pseudomonads exhibited markedly different modes of regulation. Both have unique promoter structures and genetic organization. Furthermore, both pseudomonad nucleoside hydrolase were found to contain an N-terminal extension of 30-35 amino acids that is shown to act as a periplasmic-signaling sequence. These are the first two nucleoside hydrolases, to date,that have been conclusively demonstrated to be exported to the periplasmic space. The physiological relevance of this is explained.

A comparison of auditory and visual stimuli in a delayed matching to sample procedure with adult humans.

A comparison of auditory and visual stimuli in a delayed matching to sample procedure with adult humans.

Date: December 2002
Creator: DeFulio, Anthony L.
Description: Five humans were exposed to a matching to sample task in which the delay (range = 0 to 32 seconds) between sample stimulus offset and comparison onset was manipulated across conditions. Auditory stimuli (1” tone) and arbitrary symbols served as sample stimuli for three (S1, S2, S3) and two (S4 and S5) subjects, respectively. Uppercase English letters (S, M, and N) served as comparison stimuli for all subjects. Results show small but systematic effects of the retention interval on accuracy and latency to selection of comparison stimuli. The results fail to show a difference between subjects exposed to auditory and visual sample stimuli. Some reasons for the failure to note a difference are discussed.

Consonance, Tertian Structures and Tonal Coherence in Wladimir Vogel's Dodecaphonic World

Consonance, Tertian Structures and Tonal Coherence in Wladimir Vogel's Dodecaphonic World

Date: December 2002
Creator: Hale, Jacquelyn
Description: Wladimir Vogel's (1896-1984) interest in twelve-tone composition began to develop in 1936 after hearing a series of lectures by Willi Reich, a music critic and supporter of the new music of the Second Viennese School. The transition for Vogel from a large-scale orchestral “classical” style, influenced by his study with Ferruccio Busoni in Berlin in the early 1920s, to a new technique involving dodecaphony is apparent in his instrumental writing, the third and fourth movements of the Konzert für Violine und Orchester (1937), as well as in his vocal writing, the Madrigaux for mixed a cappella choir (1938/39). Vogel's twelve-tone works exhibit tertian structures which are particularly emphasized by triads located as consecutive pitches within the rows. Emphasis on tertian structures are not limited to small-scale segmentation of the rows but can also be seen in the structural and tonal organization of complete movements and works. A primary example is the Konzert für Violoncello und Orchester (Cello Concerto) (1955) in which, on a smaller scale, the presentation of the row emphasizes both diminished and minor triads, and at the macro level, the structural triadic relationships unify passages within individual movements as well as the concerto as a whole. Since the ...

The Contributions of Armenian Composers to the Clarinet Repertoire: An Annotated Bibliography of Selected Works, A Lecture Recital, Together with Three Recitals of Selected Works by Khachaturian, Bax, Castelnuovo-Tedesco, Lutoslawski, Nielsen, Burgmüller, and Others

The Contributions of Armenian Composers to the Clarinet Repertoire: An Annotated Bibliography of Selected Works, A Lecture Recital, Together with Three Recitals of Selected Works by Khachaturian, Bax, Castelnuovo-Tedesco, Lutoslawski, Nielsen, Burgmüller, and Others

Date: December 2002
Creator: Wolverton, Cynthia Kay
Description: With the exception of the music of Aram Khachaturian, the output of Armenian composers has been largely overlooked. This small Middle-Eastern country with a population of almost four million and an intriguing history indeed has a rich musical heritage. From its roots in sacred music and folksong, Armenian music has evolved into a unique blend of national elements and Western art music. Although it remains largely undiscovered, there is an entire repertoire of works in this aesthetic. The Trio for clarinet, violin, and piano by Khachaturian has long been a standard in the clarinetist's repertoire. This project brings to light lesser-known works of other Armenian composers. After providing a brief history of Armenia and her music (Chapter 2), this document presents an annotated bibliography of works using the clarinet (Chapter 3). Because there are a significant number of Armenians living outside their homeland, composers considered for this bibliography include all those of Armenian descent: those born,schooled, and presently living in Armenia, as well as those born to one or both Armenian parents residing in other countries. The bibliography includes works for unaccompanied clarinet, clarinet and piano, clarinet and orchestra, and chamber music for up to seven players. Each annotation includes ...

CT3 as an Index of Knowledge Domain Structure: Distributions for Order Analysis and Information Hierarchies

CT3 as an Index of Knowledge Domain Structure: Distributions for Order Analysis and Information Hierarchies

Date: December 2002
Creator: Swartz Horn, Rebecca
Description: The problem with which this study is concerned is articulating all possible CT3 and KR21 reliability measures for every case of a 5x5 binary matrix (32,996,500 possible matrices). The study has three purposes. The first purpose is to calculate CT3 for every matrix and compare the results to the proposed optimum range of .3 to .5. The second purpose is to compare the results from the calculation of KR21 and CT3 reliability measures. The third purpose is to calculate CT3 and KR21 on every strand of a class test whose item set has been reduced using the difficulty strata identified by Order Analysis. The study was conducted by writing a computer program to articulate all possible 5 x 5 matrices. The program also calculated CT3 and KR21 reliability measures for each matrix. The nonparametric technique of Order Analysis was applied to two sections of test items to stratify the items into difficulty levels. The difficulty levels were used to reduce the item set from 22 to 9 items. All possible strands or chains of these items were identified so that both reliability measures (CT3 and KR21) could be calculated. One major finding of this study indicates that .3 to .5 ...

DADS - A Distributed Agent Delivery System

DADS - A Distributed Agent Delivery System

Date: December 2002
Creator: Cozzolino, Clifford Joseph
Description: Mobile agents require an appropriate platform that can facilitate their migration and execution. In particular, the design and implementation of such a system must balance several factors that will ensure that its constituent agents are executed without problems. Besides the basic requirements of migration and execution, an agent system must also provide mechanisms to ensure the security and survivability of an agent when it migrates between hosts. In addition, the system should be simple enough to facilitate its widespread use across large scale networks (i.e Internet). To address these issues, this thesis discusses the design and implementation of the Distributed Agent Delivery System (DADS). The DADS provides a de-coupled design that separates agent acceptance from agent execution. Using functional modules, the DADS provides services ranging from language execution and security to fault-tolerance and compression. Modules allow the administrator(s) of hosts to declare, at run-time, the services that they want to provide. Since each administrative domain is different, the DADS provides a platform that can be adapted to exchange heterogeneous blends of agents across large scale networks.

Decision-Making at the Court of Appeals Level Involving Religious Liberty Cases

Decision-Making at the Court of Appeals Level Involving Religious Liberty Cases

Date: December 2002
Creator: Reeves, Susan Kay
Description: Many studies have been completed on factors affecting judicial decisions. Studies have focused on civil rights cases, economic cases, criminal cases, sexual discrimination and obscenity cases, but no work has specifically looked at religious liberty cases. This work examines the factors affecting United States Courts of Appeals judges' decision-making in religious liberty cases. I hypothesize that gender, race, religious background, prior judicial experience, circuit, region and litigant status will all influence the way judges vote in religious liberty cases. The explanatory power of this study is relatively low, but the results indicate that judges follow the law when making decisions in religious liberty cases.

The Development and Economic Impacts to the State of Texas from the Construction of Interstate 69

The Development and Economic Impacts to the State of Texas from the Construction of Interstate 69

Date: December 2002
Creator: Pettibon, Gregory Jason
Description: Regional population growth and increasing trade with Mexico are creating severe traffic congestion along Interstate 35 and at the Laredo bridge crossings. The construction of a new Interstate Highway 69 has been offered as one solution to this problem. This analysis examines the economic impacts of building Interstate 69 and its potential impact on job creation in the counties along its projected path. Using the IMPLAN input-output modeling system, construction of Interstate 69 will support $4.2 billion in economic activity in the counties through which it will pass. More importantly, based on an analysis of Interstate 27 in west Texas, it can be projected that Interstate 69 will spur a 2% gain in regional employment above any usual economic growth.
