Abraham Lincoln and the American Romantic Writers: Embodiment and Perpetuation of an Ideal
The American Romantic writers laid a broad foundation for the historic and heroic Abraham Lincoln who has evolved as our national myth. The writers were attracted to Lincoln by his eloquent expression of the body of ideals and beliefs they shared with him, especially the ideal of individual liberty and the belief that achievement of the ideal would bring about an amelioration of the human condition. The time, place and conditions in which they lived enhanced the attraction, and Lincoln's able leadership during the Civil War strengthened their estimation of him. His martyrdom was the catalyst which enabled the Romantic writers to lay the foundation of the Lincoln myth which has made his name synonymous with individual freedom everywhere even today.
Academic Achievement Among Language-Impaired Children as a Function of Intensive Preschool Language Intervention
Parents and professionals are concerned about the long-term effects of language problems on later academic, communicative and behavioral functioning of children. The purpose of this study was to examine the relationship of level of language impairment with type of class placement, reading achievement, and social emotional functioning. Subjects were 19 children, aged 4 years, 10 months through 10 years, 4 months, who had previously been enrolled in a preschool language development program. Statistical analyses were performed on data from the Kaufman Assessment Battery for Children (K-ABC), Test of Early Reading Ability (TERA), and the Achenbach Child Behavior Checklist (CBC). Results do not support a relationship between level of language impairment and academic or social/emotional functioning.
Academic Achievement: Examining the Impact of Community Type at a Small Liberal Arts College in Texas
Hierarchical regression was used to determine if high school community type is an effective predictor of academic success when controlling for demographics, prior academic achievement, socioeconomic status, and current commitment or work habits for students entering Austin College in 1992,1993, and 1994 . Findings revealed that there is a relationship between attending high school in community types of rural and independent town controlling for the effects of SAT scores, high school rank, sex, and late application deposit on first semester grade point average.
Active or Passive Voice: Does It Matter?
This thesis reports on the use of active and passive voice in the workplace and classroom through analysis of surveys completed by 37 employees and 66 students. The surveys offered six categories of business writing with ten sets of two sentences each, written in active and passive voice. Participants selected one sentence from each set and gave a reason for each selection. The participants preferred active over passive 47 to 46 percent of opportunities, but they preferred mixed voice over both, 49 percent. The participants preferred active only for memos to supervisors; in the other five categories they preferred passive or mixed voice. Both males and females preferred mixed voice, and age appeared to influence the choices. They cited context as the most common reason for using passive.
The Activities of Disaster Relief Organizations During the Permanent Housing Phase of Recovery: a Case Study Analysis
This study investigates the recovery efforts provided for low income and ethnic minority populations by organizations during the permanent housing phase of recovery in Watsonville, California, following the Loma Prieta earthquake of October 17, 1989. The case study format is used to discover what activities were performed and why each organization chose to perform them. Dynes and Quarantelli's (1968) typology of organization is used to explain how and why established, expanding, extending and emergent organizations participated in the recovery efforts. The findings indicate that the type of organization dictated the kind of tasks each organization performed. Organizations maintained activities during recovery for which they had experience, expertise and proficiency.
Acts of Survival: the Plight and Prospects of Dallas Theatre
A comprehensive investigation examines the decline and changes that have affected Dallas regional theatre development from the dream of Margo Jones in the 1940s to the proliferation of emerging theatres in 1993. Changing economic conditions, lack of audience support, and shortages of performance space have contributed to an exodus of Dallas actors and artists. Reviewed are measures to reverse this trend, including funding changes, awareness campaigns, improved inter-theatre cooperation, and guidelines for audience development. The study's conclusion notes that theatres do, indeed, have a natural life cycle, but with renewed emphasis on audience development and self-sufficiency, theatres in Dallas can endure and contribute to an enlarged sense of civic pride.
N-Acylethanolamines and Plant Phospholipase D
Recently, three distinct isoforms of phospholipase D (PLD) were identified in Arabidopsis thaliana. PLD α represents the well-known form found in plants, while PLD β and γ have been only recently discovered (Pappan et al., 1997b; Qin et al., 1997). These isoforms differ in substrate selectivity and cofactors required for activity. Here, I report that PLD β and γ isoforms were active toward N-acylphosphatidylethanolamine (NAPE), but PLD α was not. The ability of PLD β and γ to hydrolyze NAPE marks a key difference from PLD α. N-acylethanolamines (NAE), the hydrolytic products of NAPE by PLD β and γ, inhibited PLD α from castor bean and cabbage. Inhibition of PLD α by NAE was dose-dependent and inversely proportional to acyl chain length and degree of unsaturation. Enzyme kinetic analysis suggested non-competitive inhibition of PLD α by NAE 14:0. In addition, a 1.2-kb tobacco (Nicotiana tabacum L.) cDNA fragment was isolated that possessed a 74% amino acid identity to Arabidopsis PLD β indicating that this isoform is expressed in tobacco cells. Collectively, these results provide evidence for NAE producing PLD activities and suggest a possible regulatory role for NAE with respect to PLD α.
Ádám's Conjecture and Its Generalizations
This paper examines idam's conjuecture and some of its generalizations. In terms of Adam's conjecture, we prove Alspach and Parson's results f or Zpq and ZP2. More generally, we prove Babai's characterization of the CI-property, Palfy's characterization of CI-groups, and Brand's result for Zpr for polynomial isomorphism's. We also prove for the first time a characterization of the CI-property for 1 SG, and prove that Zn is a CI-Pn-group where Pn is the group of permutation polynomials on Z,, and n is square free.
Adélaide Labille-Guiard and Elisabeth Vigée-Lebrun: Portraitists in the Age of the French Revolution
This thesis examines the portraiture of Elisabeth Vigée-Lebrun and Adélaide Labille-Guiard within the context of their time. Analysis of specific portraits in American collections is provided, along with an examination of their careers: early education, Academic Royale membership, Salon exhibitions, and the French Revolution. Discussion includes the artists' opposing stylistic heritages, as well as the influences of their patronage, the French art academy and art criticism. This study finds that Salon critics compared their paintings, but not with the intention of creating a bitter personal and professional rivalry between them as presumed by some twentieth-century art historians. This thesis concludes those critics simply addressed their opposing artistic styles and that no such rivalry existed.
Adolescent Pregnancy: Voices Heard in the Everyday Lives of Pregnant Teenagers
The purpose of this study is to examine the problems that pregnant teenagers encounter at school and at home while they are trying to complete their high school education. Data were collected by in-depth interviews. Twenty pregnant adolescents, who were between the ages of 15 through 18, and were participants in a special teen pregnancy program were interviewed. The major findings in this study included the respondents': 1) unstable family life histories, 2) denial that they were pregnant, 3) need for self-identity as an adult, 4) conflict with parents and 5) motivation to complete their high school education. This study points to the need for more research on the problems that pregnant adolescents encounter in their everyday lives.
Advanced Molecular and Microbial Techniques: a Complete Laboratory Notebook
The purpose of this project is to produce a complete and thorough notebook that may be used to supplement laboratory coursework. Its intent is to be used primarily by the students to aid them in understanding background information and the proper laboratory procedures involved in various types of experiments. The laboratory notebook is a summation of all the experiments and procedures used in the six-credit hour Advanced Microbial and Molecular Biology (BIOL 5160) course offered during the summer semester at the University of North Texas.

Advising the ARVN: Lieutenant General Samuel T. Williams in Vietnam, 1955-1960
Beginning in 1954, the United States Army attempted to build a viable armed force in South Vietnam. Until the early 1960s, other areas commanded more American attention, yet this formative period was influential in later United States involvement in Vietnam. This thesis examines United States advisory efforts from 1955 to 1960 by analyzing the tenure of Lieutenant General Samuel T. Williams as Chief of the Military Assistance Advisory Group in South Vietnam. During Williams's tenure, the communist forces in the north began the guerrilla insurgency in earnest. Williams's failure to respond to this change has been justly criticized; yet his actions were reflective of the United States Army's attitude toward insurgencies in the late 1950s.
AIDS Preventative Behavior Among Taiwanese University Students
This study used the Health Belief Model to examine the predictors of AIDS preventive behavior. The independent variables were the variables of individual perception, modifying factors (psychological variables), and likelihood variables. The respondents, the Taiwanese students of the University of North Texas, were influenced both by Chinese sexuality and Western values in their AIDS-risk behavior. The results revealed that 90% of the respondents were misinformed on the availability of AIDS vaccine. In addition, a majority of the students were either abstaining from sex or practicing monogamy. Using Pearson's correlation coefficient and multiple regression analysis, this study found that the psychological variables rather than cognitive variables significantly influenced the respondents' AIDS preventive behavior. Finally, suggestions were made for future research on AIDS, and for AIDS preventive behavior campaigns.
Albert Speer at Nuremberg
This thesis examines Albert Speer, minister of armaments in Germany during World War II, and the charges against him during the trial of the major war criminals in Nuremberg, Germany, 1945-1946. This thesis portrays Albert Speer as a good man enticed by the power of his position and subsequently playing a role in the crimes of the Third Reich. Primary sources included the Nuremberg Trial proceedings published by the International Military Tribunal and Speer's books, Inside the Third Reich; Spandau: The Secret Diaries; and Infiltration. The thesis has six chapters: preface, biography, the charges against Speer, the verdict, the aftermath concerning his time in Spandau Prison, and a conclusion. Albert Speer accepted his guilt, yet came to resent his imprisonment and questioned the validity of the trial.
Alcohol Use, Violence, and Psychological Abuse in Intimate Relationships
Women in distressed relationships who had sustained severe psychological abuse and either no, moderate, or severe violence from their partner were included (N = 93). Men's and women's alcohol use did not differ with level of violence. Different patterns were found in the moderate violence group regarding women's beliefs about their partner's substance problem, men's psychological abuse, and the relationship of men's and women's quantity of alcohol use and times intoxicated. Uncertainty resulting from moderate violence may strengthen the emotional impact of psychological abuse. Even when psychological abuse is exacerbated by violence, women may use active coping techniques rather than drinking to cope with abusive relationships. The findings suggest that an inordinate focus on alcohol abuse may be ineffective in combating the problem of domestic violence.
Alcoholism and the Family: The Destructive Forces in Hardy's Tess of the D'urbervilles
This study examines the forces which shaped the main character--Tess Durbeyfield--in Hardy's novel in terms of the effects which her alcoholic family had upon her mental and emotional potential and which ultimately become the determining factors in her self-destruction. Using the elements and patterns set forth in the literature regarding the dynamics of the alcoholic family, I attempt to show that Hardy's novel may best be understood as the story of a woman whose life and destiny are controlled by the consequences of her father's alcoholism. This interpretation seems to account best for many elements of the novel, such as Tess's destruction, and provides a rich appreciation of Hardy's technique and vision.
Aldo Rossi: From Modern to Post-Modern Architecture, 1960-1990
The purpose of this thesis is to discuss the stylistic development of the Italian architect Aldo Rossi from Modern to Post-Modern design. A summary of the Modern architectural movement is presented along with an analysis of the developments in Post-Modern architecture since 1960. The influence of Italian culture on Rossi's career is discussed through a brief survey of Ancient Roman archetypal motifs and Italian architecture of the early 20th century. Several key buildings proposed or constructed by Rossi from 1960-1990 are discussed based on his concepts of analogy, typology, morphology and rationalism.
Algebraic Number Fields
This thesis investigates various theorems on polynomials over the rationals, algebraic numbers, algebraic integers, and quadratic fields. The material selected in this study is more of a number theoretical aspect than that of an algebraic structural aspect. Therefore, the topics of divisibility, unique factorization, prime numbers, and the roots of certain polynomials have been chosen for primary consideration.
American Literary Pragmatism : Lighting Out for the Territory
This thesis discusses pragmatist philosophy in the nineteenth century and its effect on American literature of the time.
American Sandwich: West Coast, East Coast, in Between
The thesis begins with an introduction, followed by six short stories. The stories that follow span three or four regions of the American landscape and three or four decades of the twentieth century. What drives each story is the isolation of both narrator and main character (when these are not the same) from the world of the story. In each story, there is either a sense of wanting to belong or an urge to escape, or both. The paradox--also the writer's paradox--is that if one belongs, one has no need to escape; if one escapes, one can never belong.
Americans who did not wait: the American Legion of the Canadian Expeditionary Force, 1915-1917
This study examines the five American Legion battalions of the Canadian Expeditionary Force formed in 1915 specifically to recruit American volunteers for the Canadian overseas contingent of the First World War. This study reviews the organization of Canada's militia and Anglo-American relations before examining the formation of the American Legion, the background of its men, and the diplomatic repercussions it sparked. This study is based largely on material in the Public Archives of Canada including war records and the personal papers of several participants. During its brief existence, the American Legion precipitated constitutional, diplomatic, and political problems. The issues the American Legion raised were mostly solved by America's entry in the war. The episode hastened the maturity of Canada as a nation.
An Analysis of Dominick Argento's "Peter Quince at the Clavier": the Music and Its Relationship to the Text
Dominick Argento (b. 1927) occupies an important position among American composers. This thesis discusses his 1980 choral work Peter Quince at the Clavier: Sonatina for Mixed Chorus and Piano Concertante. On the surface, the choral and piano parts of this four movement work often sound dissimilar. To create unity within this composition, Argento utilizes a small number of generative elements that govern the pitch, intervallic, and rhythmic dimensions of the composition. This thesis also discusses the relationship between the music and the text, a poem by Wallace Stevens (1879-1955).
Analysis of Memory Interference in Buffered Multi-processor Systems in Presence of Hot Spots and Favorite Memories
In this thesis, a discrete Markov chain model for analyzing memory interference in multiprocessors, is presented.
An Analysis of Refuse Derived Fuel as an Environmentally Acceptable Fuel Alternative for the Cement Industry
Resource recovery is an attractive alternative to the waste disposal problem. The chief by-product of this process, refuse derived fuel (RDF) can be co-fired in traditional coal burning facilities. The cement industry is a potential user of RDF. This study, based on a test burn done at Texas Industries Inc. in Midlothian, Texas, demonstrated the technical, environmental, and economic feasibility of using RDF fuel in a cement kiln. Technically, the cement showed no deleterious effects when RDF was substituted for coal/natural gas at 20% by Btu content. Environmentally, acid rain gases were reduced. Economically, RDF was shown to be a cost effective fuel substitute if a resource recovery facility was erected on site.
Anatomy of Loss
Anatomy of Loss contains a foreword, which discusses the place of autobiography in fiction, and five original short stories.
'...and one of time.': A Composition for Full Orchestra with Narration
‘...and one of time.' is a reinterpretation of a small musical moment from Philip Glass' opera, Einstein on the Beach, centered around the phrase "Berne, Switzerland 1905." This reinterpretation is realized through the use of several different compositional techniques including spectral composition, micropolyphony and dodecaphony, as well as the application of extra-musical models developed by Alan Lightman, John Gardner, Italo Calvino and Albert Einstein.
Andrejs Jurjāns as Symbol of Latvian Identity: Native Folk Songs in his Large-Scale Symphonic Works
This thesis presents a study of Andrejs Jurjāns' significant symphonic works as informed by a native musicologist, Professor Jānis Torgāns, and illuminates Jurjāns' role within the cosmopolitan framework of nationalism in music.
Androgyny and Managerial Effectiveness in a Total Quality Management Organization
The majority of studies concerning psychological sex and management style have indicated that people consider the masculine style of managing to be the most popular. However, such studies are out of date and/or were usually measuring the perceptions of surveyed college students. Few studies have focused on successful managers in successful organizations. A modified version of the Bern Sex Role Inventory was distributed to 52 managers in a Total Quality Management organization. This study hypothesized that successful managers would be androgynous managers. The results of the study indicated that successful managers are androgynous managers, and that there is no significant difference in the number of female and male androgynous managers.
The Angel in the House and The Woman in White: The Unfolding and Decoding of a Victorian Stereotype
Abstract: Modern readers frequently perceive female characters in Victorian novels as insipid and inane, blaming the static portrayals on the angel in the house stereotype attributed to Coventry Patmore's poem of the same name. The stereotype does not accurately reflect the actual Victorian woman's life, however. Examining how the stereotype evolved and how the middle-class Mid-Victorian woman really lived provides insight into literary devices authors employed either to reinforce the angel ideal or to reconcile the ideal with the real. Wilkie Collins's portrayal of Marian Halcombe in The Woman in White features a dynamic female who has both androgynous characteristics and angel-in-the-house qualities, exemplifying one more paradox in a society riddled with contradictions.
Anger and Hostility Measures: Effects of Social Desirability
Individuals responding in a socially desirable (SD) fashion, rather than in a manner that reflects their true behavior, has been a problem for self-report questionnaires since their inception. The purpose of this study was to examine the hypothesis that the probability an item is endorsed on a self-report measure of anger is directly proportional to the rated SD of that item. Eighty-two subjects completed the Buss-Durkee Hostility Inventory (BDHI), the Profile of Moods State (POMS), and the State- Trait Anger Expression Inventory (STAXI). A probability of endorsement was computed for each of the measures' items. Twenty additional subjects rated the measures' items for SD. Each item's SD rating was paired with the probability the item was endorsed to produce a correlation coefficient for each measure. Results strongly support the stated hypothesis. Directions for future research are discussed.
Anger/Hostility: Reliability of Measurement and Correlates of Health History
The purpose of this study was to (1) assess the reliability and validity of anger/hostility measures, (2) examine the relationship between anger/hostility and other negative emotions, and (3) examine the relationship between anger/hostility and health history. Sixty-five subjects were given the Buss Durkee Hostility Inventory (BDHI), the State-Trait Anger Expression Inventory (STAXI), the Profile of Mood States pomsS), the Clinical Analysis Questionnaire (CAQ), the State-Trait Anxiety Inventory (STAI), the Health and Wellness Attitude Inventory (HWAI), and a health questionnaire designed to provide information about past disease and alcohol/drug use. Overall, the BDHI and POMS displayed good test-retest reliability. All six of the global indices of anger/hostility intercorrelated at a significant level, thus demonstrating good concurrent validity. The six global measures of anger/hostility also correlated at a significant level with other negative emotions.
The Angoff Method and Rater Analysis: Enhancing Cutoff Score Reliability and Accuracy
At times called a philosophy and other times called a process, cutting score methodology is an issue routinely encountered by Industrial/Organizational (I/0) psychologists. Published literature on cutting score methodology appears much more frequently in academic settings than it does in personnel settings where the potential for lawsuits typically occurs more often. With the passage of the 1991 Civil Rights Act, it is no longer legal to use within-group scoring. It has now become necessary for personnel psychologists to develop more acceptable selection methods that fall within established guidelines. Designating cutoff scores with the Angoff method appears to suit many requirements of personnel departments. Several procedures have evolved that suggest enhancing the accuracy and reliability of the Angoff method is possible. The current experiment investigated several such procedures, and found that rater accuracy methods significantly enhance cutoff score reliability and accuracy.
An Animated Screenplay Adaptation Based on John R. Erickson's Novel: The Adventures of Hank the Cowdog
Screenplay for animated feature film. Story and characters are based on a short novel, The Adventures of Hank the Cowdog. first in a series. This adaptation aims to translate the humor and unique dog-centered perspective of the original source into the medium of film. Hank the Cowdog, head of security on an isolated ranch, works undercover inside a pack of coyotes to solve a series of chicken murders. To solve the case, Hank defends his ranch, sheep and chickens from a devious and powerful coyote leader, Scraunch. With help from a variety of friends and a change in attitude, Hank saves the ranch. Screenplay places detective film conventions in an action-adventure cartoon format. Thesis includes notes on adaptation process.
Animations: A Composition for Percussion and Computer Music on Tape
Animations is a composition in six movements (Fish, Seals, Birds, Cats, Zebras, Snakes) for percussion and computer music on tape. One percussionist performs on various percussion instruments: two suspended cymbals, crotales, triangle, vibraphone, glockenspiel, marimba, three bongos, snare drum, field drum, large tom-tom, bass drum, kettle drum, temple blocks and vibraslap. The computer music on tape employs sampled sounds in a MIDI sequencing environment. The melodic and harmonic materials for the piece are derived from a matrix of twelve heptatonic scales. The individual movements are notated using both traditional and proportional notation systems. The score is 37 pages long with a twenty-two page analysis preceding the score. Animations is approximately nine minutes in duration.
Anion Exchange and Competition in Layered Double Hydroxides
Exchange reactions of anions, especially ferrocyanide and carbonate, with layered double hydroxides (LDHs) were investigated in relation to the origin of life on the early Earth. The effect on ferrocyanide exchange of concentration, pH, reaction time and cations are discussed. It was found that there were two different kinds of ferrocyanide species: one was that intercalated into the layered structure, occupying a site of D symmetry within the LDHs, while in the other, the ferrocyanide group retains full O symmetry. In addition, very low concentration, ferrocyanide associated with LDH will change its FTIR absorption shape. Carbonate was much more strongly intercalated than ferrocyanide into the LDHs, probably because of the strong hydrogen bonding.
Anti-Semitism and Der Sturmer on Trial in Nuremberg, 1945-1946: The Case of Julius Streicher
The central focus of this thesis is to rediscover Julius Streicher and to determine whether his actions merited the same punishment as other persons executed for war crimes. Sources used include Nuremberg Trial documents and testimony, memoirs of Nazi leaders, and other Nazi materials. The thesis includes seven chapters, which cover Streicher's life, especially the prewar decades, his years out of power, and his trial at Nuremberg. The conclusion reached is that Streicher did have some influence on the German people with his anti-Semitic newspaper Der Sturmer, but it is difficult to ascertain whether his speeches and writings contributed directly to the extermination of the Jews in World War II or simply reflected and magnified the anti-Semitism of his culture.
Aortic Baroreceptor Reflex Control of Blood Pressure: Effect of Fitness
Aortic baroreflex (ABR) control of blood pressure was examined in 7 untrained (UT) and 8 endurance exercise trained (EET) young men. ABR control of blood pressure was determined during a steady state phenylephrine infusion to increase mean arterial pressure 10-15 mmHg, combined with positive neck pressure to counteract the increased carotid sinus transmural pressure, and low levels of lower body negative pressure to counteract the increased central venous pressure. Functioning alone, the ABR was functionally adequate to control blood pressure. However, ABR control of HR was significantly diminished in the EET subjects due solely to the decrease in the ABR sensitivity. The persistent strain from an increased stroke volume resulting from endurance exercise training could be the responsible mechanism.
The Appeal of Fashion Retailing as a Career: Perceptions of Fashion Merchandising Students
This study investigated the (1) relationship of students' family and educational background to their opinions of fashion retailing as a career, and (2) preferences for fashion retail job attributes in relationship the appeal of fashion retail job profiles. A sample of 131 fashion merchandising students from five state-funded universities completed a four-part survey which measured two independent variables: student background and preferences of fashion retail job attributes and two dependent variables: opinions of fashion of retailing as a career and the appeal of fashion retail job profiles. Analyses included multiple regression, t-test, and correlations. For opinions of fashion retailing as a career, parental background was not significant while attendance at a retailing course, semester hours completed and G.P.A. had limited relationships. Fashion retail job attribute preferences were related to the appeal of fashion retail job profiles; the most preferred attribute was high personal freedom.
Applications of Reductive Analytical Techniques in the Phrygian Settings of the Orgelbüchlein by J.S. Bach
This study aims to two problematic aspects of the Phrygian mode: a. the development of a harmonic pattern at the cadence that differs from that of the other modes and of the major and minor modes as well; b. the observation that the Phrygian scale inverts all of the intervallic properties of the Major scale. The result of these two observations is that when the reductive techniques of Heinrich Schenker are applied in the Phrygian repertory, melodic and harmonic properties are brought into conflict with each other. However, application of alternative models of the Ursatz developed by Lori Burns has certain benefits for demonstrating musical properties in the Phrygian repertory.
An Approach Towards the Total Synthesis of Clonostachydiol
The syntheses of the unsymmetrical 14-membered bismacrolides have been reviewed. A total synthesis of clonostachydiol, the latest to join this family, has been attempted using trimethylsilyl acetylene as the builiding block and palladium catalyzed reactions for the formation of key bonds. The alkyne groups were introduced by Stille coupling of trimethylstannylethynyltrimethylsilane with an acid chloride for one fragment and by addition of lithiotrimethylsilyl acetylene to an aldehyde for the other. Lactic acid derivatives were chosen as starting materials for both fragments, thus introducing two of the chiral centers. The remaining stereocenters were introduced using stereoselective reductions of ketones.
Appropriating Language on the Usenet
The Usenet is a global computer conferencing system on which users can affix textual messages under 4500 different categories. It currently has approximately 4,165,000 readers, and these .readers have appropriated language by adapting it to the Usenet's culture and medium. This thesis conceptualizes the Usenet community's appropriation of language, provides insights into how media and media restrictions cause their users to appropriate language, and discusses how future media may further cause users to appropriate language. With the Usenet we have a chance to study a relatively new community bound by relatively new technology, and perhaps we can learn more about the appropriation process by studying the two.
Aqueous Solubilities and Transformation of Chlorinated Benzenes
Aqueous solubilities of twelve chlorinated benzenes were determined by two methods. In one method, the solutions in water were prepared by a vigorous stirring method followed by n-hexane extraction and GC-ECD analysis. In the second method, HPLC was used to prepare the saturated solutions. Experimental results were compared with the predictive values, the relative standard deviations are around 10%. Most of the chlorinated benzenes exhibit water induced transformations. The transformation products were either isomeric or with higher and lower numbers of chlorine substituents. The transformation phenomena can be explained by polarity, symmetry, reactivity of the chlorine atoms, and hydrophobic interactions. The mechanism of the transformation is governed by the radical mechanism.
An Argument for the Reassessment of Stravinsky's Early Serial Compositions
Between 1952 and 1957, Igor Stravinsky surprised the world of music by gradually incorporating serialism into his style of composition. Although Stravinsky still used the neo-classical trait of making strong references to the music of earlier periods, musical analyses of this transitional period have focused on serial aspects to the exclusion of anachronistic elements. Evidence of Stravinsky's possible use of musical structures adapted from earlier times is found in his consistent use of musical figures that are closely related to the cadences of the late Medieval and Renaissance eras. By fully addressing these neo-classical traits in future analyses, music theorists will gain an additional perspective, which is helpful in understanding the music of Stravinsky's transitional period.
The Aronson Cognitive Residual Evaluation Scale (ACRES): an Evaluation of Reliability with the Elderly
The Aronson Cognitive Residual Evaluation Scale (ACRES) is a new, relatively short neuropsychological test which attempts to measure residual cognitive skills. This study evaluated the ACRES test-retest reliability over a one to twelve month interval. The Trail Making Test (TMT) was included as a validation measure. Subjects were 58 males and females, aged 68 to 94, living in a retirement center or in the community. The ACRES exhibited moderate to strong reliability correlations and the TMT demonstrated low to moderate correlations with the ACRES. There was no time interval effect. Age had a negative effect on four of five ACRES subtests and gender was significant for one ACRES subtest and the TMT Part B. Percent of subjects classified as brain impaired using traditional cutoffs was higher than when age-corrected norms were used. Clinical utility of the ACRES and the TMT is discussed regarding need for age-corrected norms.
The Arrangement of Ezra Pound's Personae (1926) : An Interpretive Application of Editorial and Critical Theory
Pound foregrounded the importance of "shaping" poetic books through particular arrangements of individual poems by using his ideogrammic method as the crucial organizational principle for constructing Personae (1926). Critics have long understood Pound's use of the ideogrammic method in individual poems, but have so far ignored his application of it to the structuring of poetic books and sequences. Lea Baechler and A. Walton Litz, the editors of a 1990 edition of Personae (1926), however, have moved a crucial section of poems, and their rearrangement of the original text both disregards evidence of authorial intention and obscures Pound's innovative principles for arranging his shorter poems into meaningful sequences.
Assessing Defensiveness with the PAI: a Cross Validational Study
The use of scales on the Personality Assessment Inventory (PAI) to detect defensiveness in criminal and nonclinical samples was evaluated. Forty-five male inmates of a county jail and 38 male undergraduate psychology students were provided with incentives to complete the PAI under two conditions: standard instructions and experimental instructions to feign a specific, positive role. The sequence of instructions was counterbalanced in both samples for the purpose of examining ordering effects. A repeated measures multivariate analysis of variance (MANOVA) was performed, yielding significant main effects of condition, group and order. Additionally, a step-wise discriminant function analysis significantly predicted group membership (i.e., subjects under honest and faking conditions) with a hit rate = 84.4%. Finally, a more effective cutting score for the Positive Impression scale was recommended.
Assessing Effects of an Environmental Education Field Science Program Fostering Responsibility at an Urban Middle School
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.
Assessing Regional Gully Erosion Risk: A Remote Sensing and Geographic Information Systems Approach
Gully erosion has been established as a major source of sediment pollution in the upper Trinity River watershed in north-central Texas. This fact, along with a lack of models appropriate for a large-area gully erosion analysis established a need for a gully erosion study in the upper Trinity basin. This thesis project attempted to address this need by deriving an index indicative of gully erosion risk using remote sensing and geographic information systems (GIS) methodology. In context of previous field studies, the coarse spatial resolution of the input GIS data layers presented a challenge to prediction of gully prone areas. However, the remote sensing/GIS approach was found to provide useful reconnaissance information on gully risk over large areas.
Assessing the Effects of a Municipal Wastewater Treatment Plant Effluent on Zooplankton, Phytoplankton and Corbicula Flumina in a Constructed Wetland
Wetland wastewater treatment offers low-cost, energy efficient alternatives to conventional wastewater technologies. In this study, an artificial wetland was constructed at the City of Denton, Texas Pecan Creek Water Reclamation Plant to facilitate diazinon removal from treated effluent.
