Ion induced charge collection dynamics within Integrated Circuits (ICs) is important due to the presence of ionizing radiation in the IC environment. As the charge signals defining data states are reduced by voltage and area scaling, the semiconductor device will naturally have a higher susceptibility to ionizing radiation induced effects. The ionizing radiation can lead to the undesired generation and migration of charge within an IC. This can alter, for example, the memory state of a bit, and thereby produce what is called a "soft" error, or Single Event Upset (SEU). Therefore, the response of ICs to natural radiation is of great concern for the reliability of future devices. Immunity to soft errors is listed as a requirement in the 1997 National Technology Roadmap for Semiconductors prepared by the Semiconductor Industry Association in the United States. To design more robust devices, it is essential to create and test accurate models of induced charge collection and transport in semiconductor devices. A heavy ion microbeam produced by an accelerator is an ideal tool to study charge collection processes in ICs and to locate the weak nodes and structures for improvement through hardening design. In this dissertation, the Ion Beam Induced Charge Collection …

Differences in self-reported depression, anxiety, self-esteem, and coping were evaluated in two groups of pediatric oncology patients: newly diagnosed (less than six months post-diagnosis) (n=5) and patients on cancer treatment for seven months or longer (n=5). Participants (6 males, 4 females, ages 7-17 years) completed the Children's Depression Inventory (CDI), the State-Trait Anxiety Inventory for Children (STAIC), and the Culture-Free Self-Esteem Inventory (CFSEI-2); nine of the ten participants discussed in a semi-structured interview their personal experiences and feelings about having cancer. Although the newly diagnosed group had a higher mean score on the CDI than the 7 months or greater group, the difference was not significant (p = .054). The newly diagnosed group also had higher mean state and trait anxiety scores on the STAIC, indicating higher anxiety levels, and a slightly lower CFSEI-2 mean score, indicating slightly lower self-esteem than the 7 months or greater group, but differences were not at a statistically significant level (p>.05).

The intent of this study was to assess low-income parents knowledge and beliefs regarding child development and appropriate classroom practice and to compare their responses with those obtained from a previous survey of upper-income parents (Grebe, 1998). This study group (N=21) consisted of parents or guardians with children in a federally subsidized child-care center. Results indicated a high level of knowledge regarding developmentally appropriate practice and child development. Overall, there were no significant differences in the knowledge between the two income-levels, however, responses to several questions revealed slight differences in beliefs.

Playing Jonah's Hand: Poems is a collection of poems with a critical introduction. The introduction consists of two independent essays, both of which examine intersections between poetry and Christian theology. In the first essay I identify the imaginative faculty as the primary source of agency for the speaker in John Donne's "Holy Sonnets." Working upon Barbara Lewalski's assertion that these sonnets represent "the Protestant paradigm of salvation in its stark, dramatic, Pauline terms," I consider the role of the imagination in the spiritual transformation represented within the sequence. Donne foregrounds a Calvinistic theology that posits both humanity's total depravity and God's grace and mercy as the only avenue of transcendence. Whatever agency the speaker exhibits is generated by the exercise of his imagination, which leads him to a recognition of his sinfulness and the necessity of God's grace. In the second essay I investigate the presence of a negative theology within "Lachrimae, or Seven Tears Figured in Seven Passionate Pavans," a sonnet sequence by Geoffrey Hill. In this sequence, Hill demonstrates the possibilities that surface through an integration of negative theology with postmodern theories of language, both of which have been influenced by the philosophical writings of Martin Heidegger. The …

I want the viewers of my work to participate with me in a common experience. How I choose to communicate an experience in the work is intended to effect the viewer's level of understanding and participation. Toward this end, an exploration of nontraditional self-portraiture involving the viewer in a relationship with the artist will be used to maintain the visual dialogue imparted through the work. Utilization of recognizable symbols and icons within the work is meant to increase the clarity of my communication enhancing the viewer's involvement in the common experience. Color, as a concern will relate to the increased access and interest of the work to the viewer's experience and understanding.

The purpose of this research project is to examine the educational and job-training opportunities offered in the Lower Rio Grande Valley, and how the skills acquired from these programs assimilate with the job opportunities available in the area. Specifically, we will look at the counties of Cameron, Hidalgo, Starr, and Willacy. The central hypothesis of this project is that the Rio Grande Valley in its efforts for a more highly trained workforce may actually be enabling its workforce to seek better employment opportunities in other areas.

Si nanoparticles are new prospective optoelectronic materials. Unlike bulk Si cry-stals, Si nanoparticles display intriguing room-temperature photoluminescence. A major challenge in the fabrication of Si nanoparticles is the control of their size distribution. The rare-earth element Er has unique photo emission properties, including low pumping power, and a temperature independent, sharp spectrum. The emission wavelength matches the transmission window of optical fibers used in the telecommunications industry. Therefore, the study of Er-doped Si nanoparticles may have practical significance. The goals of the research described in this dissertation are to investigate vapor phase pyrolysis methods and to characterize the microstructure and associated defects, particles size distributions and photoluminescence efficiencies of doped and undoped Si nanoparticles using analytical transmission electron microscopy, high resolution electron microscopy, and optical spectroscopy. Er-doped and undoped Si nanoparticles were synthesized via vapor-phase pyrolysis of disilane at Texas Christian University. To achieve monodisperse size distributions, a process with fast nucleation and slow growth was employed. Disilane was diluted to 0.48% with helium. A horizontal pyrolysis oven was maintained at a temperature of 1000 °C. The oven length was varied from 1.5 cm to 6.0 cm to investigate the influence of oven length on the properties of the nanoparticles. …

This dissertation examines the role of "acceptable" feminine violence in Restoration and eighteenth-century drama and fiction. Scenes such as Lady Davers's physical assault on Pamela in Samuel Richardson's Pamela (1740) have understandably troubled recent scholars of gender and literature. But critics, for the most part, have been more inclined to discuss women as victims of violence than as agents of violence. I argue that women in the Restoration and eighteenth century often used violence in order to maintain social boundaries, particularly sexual and economic ones, and that writers of the period drew upon this tradition of acceptable feminine violence in order to create the figure of the violent woman as a necessary agent of social control. One such figure is Violenta, the heroine of Delarivier Manley's novella The Wife's Resentment (1720), who murders and dismembers her bigamous husband. At her trial, Violenta is condemned to death "notwithstanding the Pity of the People" and "the Intercession of the Ladies," who believe that although the "unexampled Cruelty [Violenta] committed afterwards on the dead Body" was excessive, the murder itself is not inexcusable given her husband's bigamy. My research draws upon diverse archival materials, such as conduct manuals, criminal biographies, and legal records, …

A craftsman’s work evolves with time, new forms arise and old forms become more refined. This research attempts to study the evolution of pots over a designated period of time. The key findings include that the approach to glazing was relatively unchanged by the evolution in the work. However,the refinements that occurred in the work allowed the glazes to impart wonderful characteristics to the forms on which they are used.

Widespread concern about the rapid growth of Medicare spending in recent years initiated a legislative response that resulted in the Balanced Budget Act of 1997. The effects of the BBA were far reaching and created shock waves throughout the health care industry. This study presents background information on the history of the Medicare home health benefit, enumerates specific provisions and goals of the BBA of 1997, examines how the BBA has changed the delivery of Medicare home health services, and proposes survival strategies for home health care providers.

Although humor is a generally accepted part of everyday life for humans, its existence, importance, and positive influence on older persons are often underestimated. The purposes of this study are to determine whether humor is a normal experience for nursing home residents, enhancing their activities of daily living, and whether it plays a role in contributing to their psychological well-being. The study includes a discussion of research on humor, particularly as it relates to the elderly and the aging process; analysis and comparisons based on interviews with residents on the subject of humor and review of their psychological state as evaluated by the MDS 2.0 nursing facility assessment; individual case studies, and anecdotes illustrating the beneficial contributions humor brings to the lives of nursing home residents.

Gunther Schuller is credited with coining the term Third Stream, meaning compositions where twentieth-century art music forms exist simultaneously with jazz. Furthermore, Schuller specifically states in the liner notes to the debut recording of Eine Kleine Posaunenmusik "The work is not a Third Stream piece." Yet the concerto alludes to jazz through a multitude of slide glissandi and plunger mute effects, Solotone mute passages, specific references to the jazz trombone styles of Tommy Dorsey and Lawrence Brown, musical quoting or indirect reference, and the use of a walking bass line in Movement V, Finale. What makes one piece Third Stream and another simply a modern composition with jazz implications? Is Third Stream primarily a compositional designation or a performance practice stipulation? How does a celebrated trombone soloist inspire and collaborate with a distinguished composer in the creation of a major work? The somewhat conspicuous title, Eine Kleine Posaunenmusik, seems to point towards Mozart's famous string serenade Eine Kleine Nachtmusik. What connection to Mozart, if any, does Schuller's title suggest? All of these questions are elucidated in this study through careful investigation and research of Gunther Schuller's Eine Kleine Posaunenmusik. New interviews with John Swallow and Gunther Schuller are included.

The graying of America will have implications for all areas of society, especially the delivery of long-term care services. Many older individuals are aging in place, a phenomenon that is apparent at Dickinson Place, a church-sponsored low-income housing property for the elderly in Dallas, Texas, where the average age of residents has risen from 65 in the early 1970s to 78 in 1999. This change has prompted the board of directors to review the facility's mission, its physical plant, and the services it provides for strategic planning purposes, to ensure that Dickinson Place can continue to meet the needs of its residents both now and in the future.

Condom trace evidence must not be overlooked in sexual assault cases; understanding the chemical and physical characteristics of condoms is imperative if condoms are to be useful evidence. Previous research shows that condom identification is possible, but it is equally important to evaluate durability of condom residues versus time. Using FT-IR, this study examined vaginal swabs from subjects who self-sampled at intervals for up to 72 hours after having intercourse with a condom. This study investigated whether age and the stage of the menstrual cycle affected the durability of residues in the vagina over time. This study revealed that condoms containing nonoxynol-9, silicone-based lubricants, and particulates provide valuable information for identification, and that nonoxynol-9 specifically withstands the vaginal environment for up to 72 hours. Additionally, age and menstrual cycle both appeared to have an effect on the durability of residues although larger sample size is desirable.

Document that details the conception, evolution and conclusions of a body of work consisting of seven prints executed in the printmaking technique of intaglio printing in the manner of the state print. The work is discussed by explaining the visual and conceptual associations that occur in an "Alice In Wonderland" manner, where the initial idea is paired with seemingly unrelated topics to establish a progressive visual language. This language is further supported by discussing a comparative of the state print with the idea of the sketchbook as a tool of thought generation and elaboration. The technical aspects of intaglio and the choice of techniques utilized are discussed to support this comparison. How the quality of the prints reflects the quality of the sketchbook and how these techniques combine with the conceptual reasoning, which result in the body of work. Findings for the work are based on three questions that deal with the progression of conceptual reasoning, predictability of recurring ideas and the intentions of the technical choices made.

This study is an investigation of the perceived attitudinal differences between administrators and faculty toward research and teaching at three Saudi Arabian universities, King Saud University (KSU), King Fahd University of Petroleum and Minerals (KFUPM), and the Islamic University (IU). The researcher also investigated the effect of several variables, such as rank, university, and academic field on administrators and faculty members' attitudes toward teaching and research. Little Attention has been given to studies that examine the differences between faculty and administrators with regard to their attitudes toward the priorities of teaching and research in Saudi Arabian institutions. Also, little research has been conducted regarding the effects of rank and academic field on faculty attitudes in Saudi Arabian institutions. The author used a mail survey and collected 518 useable responses from a total of 710 questionnaires distributed. Factor analysis, MANCOVA, MANOVA, and ANOVA were the statistical methods employed in data analysis. Five attitudes were identified as a result of factor analysis: (a) attitudes toward teaching; (b) attitudes toward research; (c) mission; (d) promotion; and (e) interest. Results indicated that there was a significant difference between faculty and administrators regarding teaching and resea4rch. Administrators showed stronger attitudes toward teaching than faculty at …

Elder abuse first received national attention in 1980, as the subject of a congressional investigation. Now, 20 years later, establishing successful strategies of identification, subsequent intervention, and prevention of abuse is of paramount importance; but progress toward this goal is hindered by lack of consensus as to the definition of elder abuse, and the use of vague, confusing, and sometimes contradictory terms in its discussion. In this paper, both social research and professional approaches and legal approaches to the definition of elder abuse are surveyed, as are definitions formulated for the National Elder Abuse Incidence Study conducted by the National Center on Elder Abuse. The continuing need for a universal or standard definition is emphasized.

Spontaneously active monolayer neuronal networks cultured on photoetched multimicroelectrode plates (MMEPs) offer great potential for use in studying neuronal networks. However, there are many problems associated with frequent, long-term use of MMEPs. The major problems include (1) polysiloxane insulation deterioration and breakdown, (2) and loss of gold at the gold electroplated indium-tin oxide (ITO) electrodes. The objective of this investigation was to correct these major problems. Quality control measures were employed to monitor MMEP fabrication variables. The phenotypes of polysiloxane degradation were identified and classified. Factors that were found to contribute most to insulation deterioration were (1) moisture contamination during MMEP insulation, (2) loss of the quartz barrier layer from excessive exposure to basic solutions, and (3) repetitive use in culture. As a result, the insulation equipment and methods were modified to control moisture-dependent insulation deterioration, and the KOH reprocessing solution was replaced with tetramethylguanidine to prevent damage to the quartz. The problems associated with gold electroplating were solved via the addition of a pulsed-DC application of gold in a new citrate buffered electroplating solution.

This research examines the effects of task interspersal and density of reinforcement on several behaviors of an autistic 6-year-old boy during the performance of a visual matching task and two auditory matching tasks. Experiment 1 investigated the effects of interspersing high and low accuracy tasks on correct matching responses, positions of matching responses, looking away, and self-injurious behavior (SIB). The effects of interspersed trials were evaluated using an ABAB multiple treatments design. Results indicated that interspersed trials produced slightly more correct responses during the visual matching task; however, correct responses decreased during the other two tasks. The use of interspersed trials also decreased looking away from the stimuli and SIB. Experiment 2 evaluated the effects of reinforcement density apart from task interspersal. Two conditions, reinforce-corrects-only and reinforce-all-responses, were compared in Experiment 2. Correct responses increased slightly for all three tasks during the reinforce-all-responses condition. Looking away and SIB were very infrequent throughout Experiment 2.

The recruitment and retention of teachers demand attention with estimates of two million new teachers needed in the next decade. Hiring under qualified teachers necessitates adequate induction programs. Development of a recommendation for a teacher induction program comprises the purpose of the study. The recommended induction and support program addresses the activities perceived as valuable by both mentors and mentees. The researcher describes the mentor programs currently in place in Region XI in northern Texas by surveying the mentors and mentees; of particular relevance is a determination and description of the program model in place. Data sources include the literature review and information obtained from Region XI mentors/mentees. Data shows the model in Region XI is primarily a colleague model. Mentors and mentees are matched for grade level, content area and physical proximity. Three of the most frequently occurring activities are in the category emotional support, three in logistical concerns, two in systems information, one in student management, and one in instructional support. Mentees believe those activities associated with classroom management and organization and developing confidence and self-esteem are most important. Mentors concur. Specific recommendations for structuring a comprehensive beginning teacher induction and support program include reexamining the program currently …

The Great Depression elucidated the shortcomings of the banking system and its control by Wall Street. The creation of the Federal Reserve System in 1913 was insufficient to correct flaws in the banking system until the Banking Acts of 1933 and 1935. A.P. Giannini, the American-Italian founder of the Bank of America and Mormon Marriner S. Eccles, chairman of Federal Reserve Board (1935-1949), from California and Utah respectively, successfully worked to restrain the power of the eastern banking establishment. The Banking Act of 1935 was the capstone of their cooperation, a bill that placed open market operations in the hands of the Federal Reserve, thus diminishing the power of the New York Reserve. The creation of the Federal Housing Act, as orchestrated by Eccles, became a source of enormous revenue for Giannini. Giannini's wide use of branch banking and mass advertising was his contribution to American banking. Eccles's promotion of compensatory spending and eventual placement of monetary control in the hands of the Federal Reserve Board with Banking Act of 1935 and the Accord of 1951 and Giannini's branch banking diminished the likelihood of another sustained depression. As the Bank of America grew, and as Eccles became more aggressive in …

This thesis examines existing curricula at colleges and universities about sustainability and uses results to develop an introductory post secondary course curriculum. The proposed course is organized around three major elements - - science, philosophy, and economics - - all integral to understanding sustainability. Materials needed to teach the proposed 3-semester hour course including syllabus, teaching modules, transparencies, handouts, and exams were developed. Suggestions on how to teach a one-semester hour course on sustainability and a workshop on sustainability are also presented. The following research and curriculum development was a project established and funded by the Texas Energy Office, Renewable Resources and Sustainability Program.

This study used an experimental design and a direct test of recall to provide data about teacher immediacy and student cognitive learning. Four hypotheses and a research question addressed two research problems: first, how verbal and nonverbal immediacy function together and/or separately to enhance learning; and second, how immediacy affects cognitive learning in relation to student motivation. These questions were examined in the context of video instruction to provide insight into distance learning processes and to ensure maximum control over experimental manipulations. Participants (N = 347) were drawn from university students in an undergraduate communication course. Students were randomly assigned to groups, completed a measure of state motivation, and viewed a 15-minute video lecture containing part of the usual course content delivered by a guest instructor. Participants were unaware that the video instructor was actually performing one of four scripted manipulations reflecting higher and lower combinations of specific verbal and nonverbal cues, representing the four cells of the 2x2 research design. Immediately after the lecture, students completed a recall measure, consisting of portions of the video text with blanks in the place of key words. Participants were to fill in the blanks with exact words they recalled from the videotape. …

This study related college students' remembered early relationships with parents to their depression symptoms and to dependent and self-critical subjective feelings. Undergraduates (N = 217, 118 female, 99 male) provided information regarding their current level of depression, overall functioning, subjective feelings of depression (Depressive Experiences Questionnaire), negative thoughts, interpersonal functioning, and recollections of their parents' behavior and attitudes. Depression symptoms were related to dependent and self-critical feelings and to recalled low parental care and high parental control. However, for women, paternal affection and, for men, paternal control, were unrelated to depression symptoms. Other results are inconclusive but, overall, provide evidence for the usefulness of Blatt's theory in assessing depression via dependent and self-critical subjective feelings.
