The Detection of Neuropsychological Malingering

The Detection of Neuropsychological Malingering

Date: August 2003
Creator: Liff, Christine D.
Description: The present study compared the responses of a group of simulating malingerers who were offered a monetary incentive to feign symptoms of a head injury, with the responses of head injured groups both with and without litigation, a forensic parole group, and an honest-responding control group. The following six neuropsychological measures were utilized: Rey 15-Item Memory Test, Controlled Oral Word Association Test, Finger Oscillation Test, WAIS-R Neuropsychological Instrument (Vocabulary, Information, and Similarities subtests), Booklet Category Test, and Wisconsin Card Sorting Test. The statistical concepts of floor effect, performance curve, and magnitude of error were examined. Additionally, the statistical differences in the responses of the five groups were analyzed to determine cutting scores for use in distinguishing malingerers from nonmalingerers.

A Construct Validation Study of the Personality Inventory for Youth (PIY) Using an Incarcerated Juvenile Population

A Construct Validation Study of the Personality Inventory for Youth (PIY) Using an Incarcerated Juvenile Population

Date: August 1997
Creator: Liff, Christine Denise
Description: The Personality Inventory for Youth (PIY) is a recently developed, multiscale assessment instrument designed specifically for adolescents between the ages of nine and 18. The purpose of this archival study was to establish clinical correlates for the PIY scales. PIY profiles were collected from 100 juvenile files at the Gainesville State School and examined in conjunction with the Child Assessment Scale (CAS) and the Personal Attitude Scale (PAS) to provide evidence of convergent and discriminant validity. Results indicate modest to moderate convergent validity according to Campbell and Fiske's criteria for construct validity; however, discriminant results indicate considerable overlap among traits which are not expected to be highly correlated.

A Survey of Four Original Works for Clarinet and Guitar and Their Effect on Compositional Output for the Repertoire

A Survey of Four Original Works for Clarinet and Guitar and Their Effect on Compositional Output for the Repertoire

Date: May 2013
Creator: Lignitz, Kellie
Description: In the last three decades there has been a surge in original compositions for clarinet and guitar resulting in the repertoire virtually doubling in size. However, documentation and research of original works in published sources remains limited and is quickly becoming outdated. This document reviews the current resources and reviews the newer published materials. Early chamber music works for guitar and clarinet typically required the guitar to supply harmonic support to the clarinet's upper voice, which carried the themes. An examination of the earliest works, which date from the early nineteenth century, suggests, in other words, that the two parts were not treated equally, in contrast to modern-day chamber music, in which melodic elements are proportionally balanced between the two instruments. A critical survey and comparison of four significant works from the repertoire reveals a development toward motivic balance, a progression towards melodic equality that continued in subsequent compositions. The four works surveyed are: Heinrich Neumann's Serenata Svizzera Op.29, Ferdinand Rebay's Sonata for Clarinet and Guitar No.2 in A minor, Libby Larsen's Blue Third Piece, and Gernot Wolfgang's Four Miniatures. An extensive compilation of over 300 original published and unpublished works for clarinet and guitar, bass clarinet and guitar, and ...

Wyatt Cephas Hedrick: Builder of Cities

Wyatt Cephas Hedrick: Builder of Cities

Date: May 2008
Creator: Liles, Deborah M.
Description: Wyatt Cephas Hedrick, builder and architect, was born in Virginia in 1888 and came to Texas in 1913. At his death in 1964, Hedrick's companies had managed construction projects worth more than $1.3 billion. Hedrick's architectural business designed and built edifices of all kinds, including educational facilities, hotels, military bases, railroad terminals, courthouses, and road systems. His companies built all over the United States, and in some foreign countries, but primarily in Texas. The purpose of Hedrick's structures and their architectural styles changed to accommodate historical events. This can be seen by examining many of the commissions he received during the 1920s and 1930s. Hedrick had a unique opportunity to participate in years of great change and development in Texas, and he played a vital role in the history of those times. This thesis examines the career of Wyatt C. Hedrick from his beginnings in Virginia through his years in Texas, closing in 1940. As a builder, he played a major role in changing the skylines of Texas cities, especially Fort Worth.

Southern Roots, Western Foundations: the Peculiar Institution and the Livestock Industry on the Northwestern Frontier of Texas, 1846-1864

Southern Roots, Western Foundations: the Peculiar Institution and the Livestock Industry on the Northwestern Frontier of Texas, 1846-1864

Description: This dissertation challenges Charles W. Ramsdell's needless war theory, which argued that profitable slavery would not have existed west of the 98th meridian and that slavery would have died a natural death. It uses statistical information that is mined from the county tax records to show how slave-owners on the northwestern frontier of Texas raised livestock rather than market crops, before and during the Civil War. This enterprise was so strong that it not only continued to expand throughout this period, but it also became the foundation for the recovery of the Texas economy after the war.

The Reluctant Partisan: Nathanael Greene's Southern Campaigns, 1780-1783

The Reluctant Partisan: Nathanael Greene's Southern Campaigns, 1780-1783

Date: May 2005
Creator: Liles, Justin S.
Description: Nathanael Greene spent the first five years of the American Revolution serving as a line and field officer in the Continental Army and developed a nuanced revolutionary strategy based on preserving the Continental Army and a belief that all forces should be long-service national troops. He carried these views with him to his command in the southern theater but developed a partisan approach due to problems he faced in the region. Greene effectively kept his army supplied to such an extent that it remained in the field to oppose the British with very little outside assistance. He reluctantly utilized a partisan strategy while simultaneously arguing for the creation of a permanent Continental force for the region.

Discovery and Characterization of Two Tn5 Generated pyrA Mutants in Pseudomonas putida and the Generation of Hfr Strains

Discovery and Characterization of Two Tn5 Generated pyrA Mutants in Pseudomonas putida and the Generation of Hfr Strains

Date: August 1994
Creator: Liljestrand, Laura Gail
Description: A pyrA mutation in Pseudomonas putida was isolated using transposon mutagenesis for the first time. Transposon Tn5 was used to inactivate the pyrA gene for carbamoylphosphate synthetase in these mutants. Accordingly, these mutants were defective in pyrimidine and arginine biosynthesis. The suicide vector, pM075, from Pseudomonas aeruginosa, was used to introduce the transposon into the cells. Tn5 was subsequently used to supply homology so that the plasmid pM075 could be introduced in its entirety into the Pseudomonas putida chromosome at the locus of the Tn5 insertion in the pyrA gene. Consequently, these strains exhibited high frequency of recombination and were capable of chromosome mobilization.

Earth Ascending: A composition in three movements for female voice, electroacoustic music, and video

Earth Ascending: A composition in three movements for female voice, electroacoustic music, and video

Date: August 2000
Creator: Lillios, Elainie
Description: Earth Ascending is a composition in three movements scored for female voice, electroacoustic music, and video. Composed in the Year 2000, Earth Ascending lasts approximately sixteen minutes and was created specifically for live performance in which all three elements combine to create a sonic and visual environment. As such, no single element has greater importance than any other, with each of the three performing forces assuming a foreground role at various times throughout the work. Earth Ascending is defined by a single poem written by contemporary female British poets Jeni Counzyn, Jehanne Mehta, and Cynthia Fuller. The movements are named according to the title of each poem: Earth-Body, Light-Body; Wringcliff Beach; and Pool. The movements are separated in performance by five seconds of silence and black on the video screen. The paper accompanying the score of Earth Ascending is divided into five chapters, each discussing in detail an element central to the composition itself. The Introduction presents background information, general ideas, and approaches undertaken when creating the work. Chapters 1 through 3 investigate in detail the content of the electroacoustic music, voice, and video. Chapter 4 discusses scoring techniques, revealing approaches and methods undertaken to solve issues relating to notation ...

Description: Johann Sebastian Bach's chorale preludes are varied and artistic not only in the treatment of chorale melodies, but also in the accompaniments of those chorale melodies. This study examines the accompaniments of Bach's long chorale preludes, focusing on identifying the various types and the characteristics that make them unique. This study investigates the two broad categories of accompaniments depending on whether the motives are chorale-derived or independent of the chorale. While the chorale prelude accompaniments in the first large group are closely related, the accompaniments of the chorale preludes in the second group stand independently and illustrate the vast range of Bach's compositional skill. Both groups demonstrate Bach's interest in expanding his predecessors' models, a trait that can be traced throughout all of Bach's compositional history.

Materials properties of ruthenium and ruthenium oxides thin films for advanced electronic applications.

Materials properties of ruthenium and ruthenium oxides thin films for advanced electronic applications.

Access: Use of this item is restricted to the UNT Community.
Date: May 2006
Creator: Lim, ChangDuk
Description: Ruthenium and ruthenium dioxide thin films have shown great promise in various applications, such as thick film resistors, buffer layers for yttrium barium copper oxide (YBCO) superconducting thin films, and as electrodes in ferroelectric memories. Other potential applications in Si based complementary metal oxide semiconductor (CMOS) devices are currently being studied. The search for alternative metal-based gate electrodes as a replacement of poly-Si gates has intensified during the last few years. Metal gates are required to maintain scaling and performance of future CMOS devices. Ru based materials have many desirable properties and are good gate electrode candidates for future metal-oxide-semiconductor (MOS) device applications. Moreover, Ru and RuO2 are promising candidates as diffusion barriers for copper interconnects. In this thesis, the thermal stability and interfacial diffusion and reaction of both Ru and RuO2 thin films on HfO2 gate dielectrics were investigated using Rutherford backscattering spectrometry (RBS), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). An overview of Ru and RuO2/HfO2 interface integrity issues will be presented. In addition, the effects of C ion modification of RuO2 thin films on the physico-chemical and electrical properties are evaluated.
