Thermodynamic Properties of Nonelectrolyte Solutes in Ternary Solvent Mixtures

Thermodynamic Properties of Nonelectrolyte Solutes in Ternary Solvent Mixtures

Date: August 1999
Creator: Deng, Tʻai-ho
Description: The purpose of this dissertation is to investigate the thermodynamic properties of nonelectrolyte solutes dissolved in ternary solvent mixtures, and to develop mathematical expressions for predicting and describing that behavior in the solvent mixtures. Thirty-four ternary solvent systems were studied containing either alcohol (1-propanol, 2-propanol, 1-butanol, and 2-butanol), alkane (cyclohexane, heptane, and 2,2,4-trimethylpentane) or alkoxyalcohol (2-ethoxyethanol and 2-butoxyethanol) cosolvents. Approximately 2500 experimental measurements were performed. Expressions were derived from the Combined Nearly Ideal Multiple Solvent (NIMS)/Redlich-Kister, the Combined Nearly Ideal Multiple Solvent (NIMS)/Bertrand, Acree and Burchfield (BAB) and the Modified Wilson models for predicting solute solubility in ternary solvent (or even higher multicomponent) mixtures based upon the model constants calculated from solubility data in sub-binary solvents. Average percent deviation between predicted and observed values were less than 2%, documenting that these models provide a fairly accurate description of the thermodynamic properties of nonelectrolyte solutions. Moreover, the models can be used for solubility prediction in solvent mixtures in order to find the optimum solvent composition for solubilization or desolubilization of a solute. From a computational standpoint, the Combined Nearly Ideal Multiple Solvent/Redlich-Kister equation is preferred because the needed model constants can be calculated with a simple linear regressional analysis. Model constants ...

Timed vs. Untimed Initiation Intervals and the Effects of Confidence on a Golf Putting Task

Timed vs. Untimed Initiation Intervals and the Effects of Confidence on a Golf Putting Task

Date: August 1999
Creator: Sundberg, Jeffrey D.
Description: Low, moderate, and high handicap golfers, while wearing glasses with a blinder on the side, attempted 9 putts differing in length from 5 to 21 ft under timed (less than 3.5s from grounding of club to initiation of back swing) and untimed conditions in a counterbalanced design. Confidence ratings were taken prior to and following each putt. The results revealed a significant condition by handicap group interaction (p=.021). The lower handicap group had a more consistent and lower initiation interval duration than did the moderate and high handicap players. Post interviews determined that 33 of the 35 golfers felt more comfortable in the untimed condition. However, golfers' confidence levels were not significantly different in the untimed condition as compared to the timed condition.

Tinstar and Redcoat: A Comparative Study of History, Literature and Motion Pictures Through the Dramatization of Violence in the Settlement of the Western Frontier Regions of the United States and Canada

Tinstar and Redcoat: A Comparative Study of History, Literature and Motion Pictures Through the Dramatization of Violence in the Settlement of the Western Frontier Regions of the United States and Canada

Date: August 1999
Creator: Lester, Carole N., 1946-
Description: The Western settlement era is only one part of United States national history, but for many Americans it remains the most significant cultural influence. Conversely, the settlement of Canada's western territory is generally treated as a significant phase of national development, but not the defining phase. Because both nations view the frontier experience differently, they also have distinct perceptions of the role violence played in the settlement process, distinctions reflected in the historical record, literature, and films of each country. This study will look at the historical evidence and works of the imagination for both the American and Canadian frontier experience, focusing on the years between 1870 and 1930, and will examine the part that violence played in the development of each national character. The discussion will also illustrate the difference between the historical reality and the mythic version portrayed in popular literature and films by demonstrating the effects of the depiction of violence on the perception of American and Canadian history.

Toward an Ecofeminist Environmental Jurisprudence: Nature, Law, and Gender

Toward an Ecofeminist Environmental Jurisprudence: Nature, Law, and Gender

Date: August 1999
Creator: Mallory, Chaone
Description: This thesis develops a legal theory reflecting the insights of feminism and environmental philosophy. I argue that human beings are not ontologically separate, but embedded in webs of relationality with natural others. My primary purposes are to 1) delineate ways in which institutions of modernity (such as law and science) have precipitated ecosocial crisis through the attempt to dialectically enforce mastery and control over nature and women; and 2) explore alternate political forms and ontologies which challenge the classical liberalist view of the (human) individual as a radically isolated, discrete, autonomous being. My overarching theme is that law functions as a narrative that can both hinder and enhance the promotion of ecological ideas, and how ecofeminism can contribute to transformative projects of environmental philosophy and feminist law.

Vicarious Traumatization, Secondary Traumatic Stress, and Burnout in Sexual Assault and Domestic Violence Agency Staff and Volunteers

Vicarious Traumatization, Secondary Traumatic Stress, and Burnout in Sexual Assault and Domestic Violence Agency Staff and Volunteers

Date: August 1999
Creator: Baird, Stephanie
Description: Two constructs, vicarious trauma (VT) and secondary traumatic stress (STS), describe therapists’ reactions to clients’ traumatic material. VT (TSI Belief Scale [BSL]), emphasizes cognitive belief system changes resulting from cumulative exposure to survivors. STS, (Compassion Fatigue Self-test for Psychotherapists [CFST]) combines PTSD and burnout symptomatology explaining sudden adverse reactions to survivors. Burnout (BO; Maslach Burnout Inventory [MBI]), links emotional exhaustion, depersonalization, and deficient personal accomplishment to inadequate institutional supports in interpersonally demanding work. This study investigated BSL and CFST validity, counselor trauma history, and client exposure-related VT, STS, and BO in 105 trauma counselors. Results demonstrate concurrent validity between BSL and CFST; other results dispute adequate validity. BO, and client exposure were related. Traumatized counselors scored higher than non-traumatized counselors on CFST, BSL, and SCL-90-R.

Why Orville and Wilbur Built an Airplane

Why Orville and Wilbur Built an Airplane

Date: August 1999
Creator: Jenkinson, John S.
Description: This dissertation comprises two sections. The title section collects a volume of the author's original poetry, subdivided into four parts. The concerns of this section are largely aesthetic, although some of the poems involve issues that emerge in the introductory essay. The introductory essay itself looks at slightly over three centuries of poetry in English, and focuses on three representative poems from three distinct periods: the long eighteenth century and the Romantic period in England, and the Post-war period in the United States. John Dryden's translation of Ovid's "Cinyras and Myrrha," John Keats' "Ode to a Nightingale," and James Dickey's "The Sheep Child," whatever their stylistic and aesthetic differences may be, all share a concern with taboo. Each of the poems, in its own way, embraces taboo while transgressing societal norms in order to effect a synthesis that merges subject and object in dialectical transcendence. For Dryden, the operative taboo is that placed on incest. In his translation of Ovid, Dryden seizes on the notion of incest as a metaphor for translation itself and views the violation of taboo as fructifying. Keats, in his Nightingale ode, toys with the idea of suicide and reconstructs a world both natural and mythic ...

Work Function Study of Iridium Oxide and Molybdenum Using UPS and Simultaneous Fowler-Nordheim I-V Plots with Field Emission Energy Distributions

Work Function Study of Iridium Oxide and Molybdenum Using UPS and Simultaneous Fowler-Nordheim I-V Plots with Field Emission Energy Distributions

Date: August 1999
Creator: Bernhard, John Michael
Description: The characterization of work functions and field emission stability for molybdenum and iridium oxide coatings was examined. Single emission tips and flat samples of molybdenum and iridium oxide were prepared for characterization. The flat samples were characterized using X-ray Photoelectron Spectroscopy and X-ray diffraction to determine elemental composition, chemical shift, and crystal structure. Flat coatings of iridium oxide were also scanned by Atomic Force Microscopy to examine topography. Work functions were characterized by Ultraviolet Photoelectron Spectroscopy from the flat samples and by Field Emission Electron Distributions from the field emission tips. Field emission characterization was conducted in a custom build analytical chamber capable of measuring Field Emission Electron Distribution and Fowler-Nordheim I-V plots simultaneously to independently evaluate geometric and work function changes. Scanning Electron Microscope pictures were taken of the emission tips before and after field emission characterization to confirm geometric changes. Measurement of emission stability and work functions were the emphasis of this research. In addition, use of iridium oxide coatings to enhance emission stability was evaluated. Molybdenum and iridium oxide, IrO2, were characterized and found to have a work function of 4.6 eV and 4.2 eV by both characterization techniques, with the molybdenum value in agreement with previous ...

An Adaptive Linearization Method for a Constraint Satisfaction Problem in Semiconductor Device Design Optimization

An Adaptive Linearization Method for a Constraint Satisfaction Problem in Semiconductor Device Design Optimization

Date: May 1999
Creator: Chang, Chih-Hui, 1967-
Description: The device optimization is a very important element in semiconductor technology advancement. Its objective is to find a design point for a semiconductor device so that the optimized design goal meets all specified constraints. As in other engineering fields, a nonlinear optimizer is often used for design optimization. One major drawback of using a nonlinear optimizer is that it can only partially explore the design space and return a local optimal solution. This dissertation provides an adaptive optimization design methodology to allow the designer to explore the design space and obtain a globally optimal solution. One key element of our method is to quickly compute the set of all feasible solutions, also called the acceptability region. We described a polytope-based representation for the acceptability region and an adaptive linearization technique for device performance model approximation. These efficiency enhancements have enabled significant speed-up in estimating acceptability regions and allow acceptability regions to be estimated for a larger class of device design tasks. Our linearization technique also provides an efficient mechanism to guarantee the global accuracy of the computed acceptability region. To visualize the acceptability region, we study the orthogonal projection of high-dimensional convex polytopes and propose an output sensitive algorithm for ...

Date: May 1999
Creator: Restivo, Janet DiMaria
Description: The purpose of this study was to describe a Title I inclusion program in a north Texas middle school, to evaluate the degree of its success as a high achieving program, and to analyze how closely it met the requirements of the Improving America's Schools Act of 1994. Data were collected from the learning facilitators and teachers at the middle school with the permission of the school district. This study began with extensive research on the nature of adolescents and the beliefs and characteristics of high achieving middle schools. It addressed the steps which were recommended in the literature to improve middle schools and benefit students that are at-risk of failing to master the curriculum at their grade level. The researcher concluded by reporting effective strategies being used in middle school at-risk programs. These are strategies noted by experts as successful in identified programs. The population for this study was seventh and eighth grade Title I students who attended middle school during the 1992-1993, 1993-1994, 1994-1995 and 1995-1996 school years. The data collected by the researcher are presented in two parts: the description of the Title I inclusion program; and the results of the Texas Assessment of Academic Skills tests ...

Analyzing the Financial Condition of Higher Education Institutions Using Financial Ratio Analysis

Analyzing the Financial Condition of Higher Education Institutions Using Financial Ratio Analysis

Date: May 1999
Creator: Buddy, Nancy J.
Description: The problem concerned the financial indicators used to evaluate the financial condition of the six sister higher education institutions under the authority of the Board of Regents of Oklahoma Colleges. The purposes were to determine the financial ratios that best indicate financial condition; to calculate those financial ratios for the six designated Oklahoma higher education institutions; and to evaluate and compare the financial condition of the six institutions. This study attempted to further the use of financial ratio analysis as an objective addition to subjective studies that examine an institution's definition of its mission, objectives, and goals and its own assessment of the degree to which its resources allow it to attain those goals. The data were obtained from the Integrated Postsecondary Education Data System; the financial reports were audited by independent certified public accountants and presented to the Board of Regents of Oklahoma Colleges; and John Minter Associates, Inc., provided the national norms. The set of financial ratios identified provides a means to study a single higher education institution through trend analysis and in comparison to national norms. It also works well with a sample of homogeneous institutions with interinstitutional comparison. The techniques are intended to provide a general ...

The Anglo-American Council on Productivity: 1948-1952 British Productivity and the Marshall Plan

The Anglo-American Council on Productivity: 1948-1952 British Productivity and the Marshall Plan

Date: May 1999
Creator: Gottwald, Carl H.
Description: The United Kingdom's postwar economic recovery and the usefulness of Marshall Plan aid depended heavily on a rapid increase in exports by the country's manufacturing industries. American aid administrators, however, shocked to discover the British industry's inability to respond to the country's urgent need, insisted on aggressive action to improve productivity. In partial response, a joint venture, called the Anglo-American Council on Productivity (AACP), arranged for sixty-six teams involving nearly one thousand people to visit U.S. factories and bring back productivity improvement ideas. Analyses of team recommendations, and a brief review of the country's industrial history, offer compelling insights into the problems of relative industrial decline. This dissertation attempts to assess the reasons for British industry's inability to respond to the country's economic emergency or to maintain its competitive position faced with the challenge of newer industrializing countries.

The Applicability of SERVPERF in Judging Service Quality for Biomedical Information Professionals

The Applicability of SERVPERF in Judging Service Quality for Biomedical Information Professionals

Date: May 1999
Creator: Jenkins, Sharon D. (Sharon Dezel)
Description: The applicability of SERVPERF as a tool for judging the quality of services used by biomedical information professionals was tested using standard statistical procedures. Data was gathered nationally via a combination of electronic and non-electronic forms, from Area Health Education Center (AHEC) information professionals and the results consolidated to provide information for the study. It was determined that SERVPERF was applicable in making judgements about service quality for AHEC information professionals. Their perceptions about service quality tended to have a greater influence than did their level of actual satisfaction on whether or not they planned to use a particular service in the future. There is currently no validated tool available to ascertain the quality of services offered to these valuable members of the rural health care team. This dissertation proposes to provide such a tool, and to serve as a guide or template for other professionals seeking a means to judge service quality in their own disciplines.

Assembly of Pseudomonas putida Aspartate Transcarbamoylase and Possible Roles of the PyrC' Polypeptide in the Folding of the Dodecameric Enzyme

Date: May 1999
Creator: Hongsthong, Apiradee, 1970-
Description: Aspartate transcarbamoylase (ATCase) of Pseudomonas putida consists of two different polypeptides, PyrB and PyrC' (Schurr et al, 1995). The role of the PyrC' and the assembly of PyrB and PyrC' have been studied. The ATCase made in vitro of P.putida PyrB with P.putida PyrC', and of E.coli PyrB with P.putida PyrC ' were generated under two different conditions, denaturation and renaturation, and untreated. It was found that PyrC' plays a role in the enzymatic regulation by ATP, CTP and UTP. In addition to playing a role in substrate binding, the PyrB polypeptide is also involved in effector binding (Kumar et al., manuscript in preparation). The most energetically preferred form of the P.putida WT is a dodecamer with a molecular mass of 480 kDa. The ratio between the PyrB and the PyrC' is 1:1. In studies of nucleotide binding, it was discovered that the P.putida PyrB was phosphorylated by a protein kinase in the cell extract. In the presence of 20 mM EDTA, this phosphorylation was inhibited and the inhibition could be overcome by the addition of divalent cations such as Zn2+ and Mg2+. This result suggested that the phosphorylation reaction required divalent cations. In the CAD complex of eukaryotes, phosphorylations ...

Assessing Effects of an Environmental Education Field Science Program Fostering Responsibility at an Urban Middle School

Assessing Effects of an Environmental Education Field Science Program Fostering Responsibility at an Urban Middle School

Date: May 1999
Creator: Sills, Blake
Description: The study investigated the ability of an extracurricular program to influence environmental responsibility of sixth and seventh graders. The Children's Environmental Attitude and Knowledge Survey (CHEAKS) was evaluated for appropriateness in assessing the worth of this particular environmental education strategy emphasizing water quality fieldwork and technology. CHEAKS is designed with psychometric reliability and validity that may be used in comparing disparate programs. Wilcoxon two sample tests were used to analyze data gathered from two student groups; one participated in an "Enviro-Mentals Club"; the other received no treatment. Analysis showed no significant change in environmental attitudes between groups, but did show significance (p <= 0.05) in environmental knowledge growth. Therefore, the investigated program had marginal success in influencing environmental responsibility.

Attribution to Deviant and Nondeviant Social Roles

Attribution to Deviant and Nondeviant Social Roles

Date: May 1999
Creator: Rohlman, James E.
Description: A questionnaire was used to study causal attribution to social roles as influenced by perceived deviance of the role, instructions to identify with the role, and participant gender. The perceived deviance or nondeviance of the roles was determined by a pilot study. The roles were varied randomly through 12 hypothetical events, and identification or nonidentification instructions randomly assigned. The participants were 194 male and female university students. Participants gave the cause of each event and rated the cause on five dimensions: internality, externality, stability, globality, and controllability. Causal attribution to deviant social roles was found to result in a significantly higher across-scales score and to be more internal, less external, and more global than attribution to nondeviant roles. Participant gender showed an interaction with deviance overall and on the dimensions of stability and globality due to significantly higher ratings by women participants than those by men. Identification instructions did not produce a significant effect.

Biodiversity of Dragonflies and Damselflies (Odonata) of the South-Central Nearctic and Adjacent Neotropical Biotic Provinces

Biodiversity of Dragonflies and Damselflies (Odonata) of the South-Central Nearctic and Adjacent Neotropical Biotic Provinces

Date: May 1999
Creator: Abbott, John C.
Description: The south-central United States serves as an important biogeographical link and dispersal corridor between Nearctic and Neotropical elements of western hemisphere odonate faunas. Its species are reasonably well known because of substantial collections, but there has been no concerted effort to document the extent of biodiversity and possible geographic affinities of dragonflies and damselflies of this region. The recent discoveries of Argia leonorae Garrison, Gomphus gonzalezi Dunkle and Erpetogomphus heterodon Garrison from southern and western Texas and northern Mexico suggest that Odonata species remain to be discovered in this area, particularly from far south Texas and northern Mexico. I have documented a total of 12,515 records of Odonata found in 408 counties within the south-central U.S. A total of 73 species of damselflies and 160 species of dragonflies was revealed in the region. The 233 (197 in Texas) Odonata species are distributed among 10 families and 66 genera. Illustrated family, generic, and species-level keys are provided. Since the beginning of this work in the Fall of 1993, one species has been added each to the Louisiana and Oklahoma faunas, and 12 species have been added, previously unreported from Texas, including four new to the U.S. The area of highest Odonata ...

"But a Mournful Remedy": Divorce in Two Texas Counties, 1841-1880

"But a Mournful Remedy": Divorce in Two Texas Counties, 1841-1880

Date: May 1999
Creator: Pruitt, Francelle LeNaee
Description: Little scholarship has been dedicated to nineteenth-century Texas family life and no published scholarship to date has addressed the more specific topic of divorce. This study attempts to fill that gap in the historiography through a quantitative analysis of 373 divorce actions filed in Washington and Harrison Counties. The findings show a high degree of equity between men and women in court decisions granting divorces, and in property division and custody rulings. Texas women enjoyed a relatively high degree of legal and personal autonomy, which can be attributed, in part, to a property-rights heritage from Spanish civil law.

Chaucer and the Rhetorical Limits of Exemplary Literature

Chaucer and the Rhetorical Limits of Exemplary Literature

Date: May 1999
Creator: Youmans, Karen DeMent
Description: Though much has been made of Chaucer's saintly characters, relatively little has been made of Chaucer's approach to hagiography. While strictly speaking Chaucer produced only one true saint's life (the Second Nun's Tale), he was repeatedly intrigued and challenged by exemplary literature. The few studies of Chaucer's use of hagiography have tended to claim either his complete orthodoxy as hagiographer, or his outright parody of the genre. My study mediates the orthodoxy/parody split by viewing Chaucer as a serious, but self-conscious, hagiographer, one who experimented with the possibilities of exemplary narrative and explored the rhetorical tensions intrinsic to the genre, namely the tensions between transcendence and imminence, reverence and identification, and epideictic deliberative discourse.

Client/Server Systems Performance Evaluation Measures Use and Importance: a Multi-Site Case Study of Traditional Performance Measures Applied to the Client/Server Environment

Client/Server Systems Performance Evaluation Measures Use and Importance: a Multi-Site Case Study of Traditional Performance Measures Applied to the Client/Server Environment

Date: May 1999
Creator: Posey, Orlando Guy
Description: This study examines the role of traditional computing performance measures when used in a client/server system (C/SS) environment. It also evaluates the effectiveness of traditional computing measures of mainframe systems for use in C/SS. The underlying problem was the lack of knowledge about how performance measures are aligned with key business goals and strategies. This research study has identified and evaluated client/server performance measurements' importance in establishing an effective performance evaluation system. More specifically, this research enables an organization to do the following: (1) compare the relative states of development or importance of performance measures, (2) identify performance measures with the highest priority for future development, (3) contrast the views of different organizations regarding the current or desired states of development or relative importance of these performance measures.
