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.
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.
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.
Assessment and Treatment of Object Mouthing in the Classroom: The object mouthing of a developmentally delayed 8-year-old girl was assessed and treated in a classroom setting. Two pretreatment assessments were conducted: A functional analysis indicated that object mouthing occurred across test conditions and persisted in the absence of social contingencies, and assessment of stimulus preference identified reinforcers to be used during treatments. Based on assessment outcomes, two treatments were implemented. Noncontingent sensory reinforcement was implemented during free-time and group activities, resulting in a 74.3% decrease in object mouthing across three settings. During one-on-one educational activities, presentation of academic task-trials at a high rate decreased object mouthing by 85.7%, relative to a condition in which tasks were presented at a slower rate.
Assessment of Changes in Aquatic Macrophyte Occurrence Following Introduction of Triploid Grass Carp in a North Texas Reservoir: The objectives of this project were to measure changes in frequency of occurrence of submerged macrophytes over the first two growing seasons following stocking with triploid grass carp at two fish per acre and to measure differences in macrophyte biomass between areas excluded from herbivory and adjacent control sites after 16 months following establishment of exclosures. The project also seeks to measure concentrations of fluridone following the herbicide treatment, and to compare two methods of aquatic vegetation sampling.
Biology and Energetics of Tropisternus Lateralis Nimbatus (SAY) (Coleoptera: Hydrophilidae) in a Playa on the Southern High Plains of Texas and Aquatic Coleoptera Diversity from Seven Playas on the Southern High Plains of Texas: A study of the biology of Tropisternus lateralis, a hydrophilid beetle, was conducted during the flood period of a single playa on the Southern High Plains of Texas from early June 1995 through early September 1995. Mechanism of colonization, tolerance/avoidance to drought, larval density, and secondary production were analyzed. T. lateralis colonized playas from surrounding aquatic habitats and avoided drought through aerial dispersion. Once in the playa, larval density increased over time. Secondary production was 1.31 g/m2/.25 yr. In addition, aquatic Coleoptera diversity was studied in seven playas on the Southern High Plains of Texas. A total of twenty three species were identified from the study region. Nine species not reported in playa literature were identified.
Cluster Analysis of the MMPI-2 in a Chronic Low-Back Pain Population: The Minnesota Multiphasic Personality Inventory (MMPI) is the most frequently used psychological measure in the assessment of chronic pain. Since the introduction of the MMPI-2 in 1989 only two published studies have focused on cluster analysis of chronic pain patients. This study investigated MMPI-2 cluster solutions of chronic low-back pain patients. Data was collected from 2,051 chronic low-back pain patients from a multidisciplinary pain clinic in the southwestern United States. A hierarchical clustering procedure was performed on K-corrected T-scores of the MMPI-2 using the three validity and ten clinical scales. Four relatively homogeneous subgroups were identified for each sex with the MMPI-2. In general, these results replicated the findings of previous researchers using both the MMPI and MMPI-2.
College Students' Attitudes toward Pregnancy and Women in the Work Force: The purpose of this study was to assess college students' attitudes toward pregnancy and women in the work force following the passage of the Family Medical Leave Act of 1993. Data were obtained from 347 students at a university in North Texas during the spring semester of 1997. Gender, age, employment status, parental status, and citizenship were independent variables hypothesized to influence attitudes toward pregnant working women. Gender was significant for the following factors: pregnant women as employees (p<.001), emotional stereotypes (p<.001), choosing family or career (p<.001), and physical limitations (p<.001). Those students 17-19-years-old had a more negative attitude toward pregnant women choosing work over family (p<.001) than did the older students.
A Comparative Analysis of the "Dies Irae" in Mozart's Requiem and Cherubini's Requiem in D Minor: The thesis speculates on the possible influence of Mozart's Requiem on Cherubini's Requiem in D Minor, concluding that Cherubini's setting of the Sequence ("Dies irae") was indeed influenced by Mozart's setting of this liturgical text both on the micro and macro levels.
Comparing Quality of Life: American and Portuguese Cancer Patients with Hematological Malignancies: The purpose of this study is to investigate the differences and similarities of quality of life (QoL) in American and Portuguese cancer patients with hematological malignancies as well as the robustness of the measures cross-culturally. Portuguese participants were 98 patients and 49 accompanying persons and the American participants were 55 patients and 22 accompanying persons. Fifty (Portuguese sample) to 40% (American sample) of the patients came with an accompanying person who answered the questionnaire concerning the patient's QoL. The two cultural groups were characterized in terms of QoL (measured by the SF-36 and the FLIC), social support (Social Support Scale), socio-demographic and clinical variables. Portuguese patients reported a higher QoL. However, this result could be attributable to the fact that the two cultural samples differ in socio-economic status. The measures seem to be comparable for the Portuguese and American samples, at least in what concerns reliability and concurrent validity.
A Comparison of Nutrition Topics and Teaching Methods in Hospitality Management Programs in the United States and International Schools: One hundred forty-nine hospitality and culinary programs located in the U.S. and 49 hospitality and culinary programs located in other countries were examined to identify the differences of nutrition topics taught and teaching methods/resources used in undergraduate hospitality management and culinary programs.
A Construct Validation Study of the Personality Inventory for Youth (PIY) Using an Incarcerated Juvenile Population: 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.
Conversations with the Master: Picasso's Dialogues with Velazquez: This thesis investigates the significance of Pablo Picasso's lifelong appropriation of formal elements from paintings by Diego Velazquez. Selected paintings and drawings by Picasso are examined and shown to refer to works by the seventeenth-century Spanish master.
Descriptions, Life History and Case-Building Behavior of Culoptila cantha (Trichoptera: Glossosomatidae) in the Brazos River, Texas: Larval, pupal and adult samples of Culoptila cantha, from a large riffle of the Brazos River in north-central Texas from January, 1995 to March, 1997, indicated a predominately trivoltine cycle during both years; the over-wintering generation spanned 6-7 months and warm-season generations spanned 2-3 months. Eggs, larvae of all instars, larval cases, case reconstruction progression and behavior, pupae, and adults are described.
The Desires of Rebecca Horn: Alchemy and the Mechanics of Interpretation: The purpose of this thesis is to analyze the use of alchemy within the work of Rebecca Horn, to elucidate its presence in her work, and to illuminate its purpose as a personal philosophy and as a creative tool. The use of alchemy within Horn's work occurs as a process of revelation and transformation. Alchemy is revealed as a spiritual philosophy and as an interpretative system through the changes that occur in Horn's oeuvre. Throughout Horn's career, alchemy has developed into an interpretive system, a type of spiritual and cosmic perspective, that allows the artist to study, access, and meld diverse realities (sacred and profane) and diverse social systems (religious and scientific) into a more holistic and spiritually infused reality for herself and society-at-large. The purpose of her work is to help reinvest contemporary life with a spiritual presence by offering a model and a means of bringing the sacred into the profane.
Development of a Simplified Fracture Toughness Tool for Polymers: This thesis presents research toward the development of a simple inexpensive fracture toughness tool for polymeric materials. Experiments were conducted to test the specimen configuration and the fracture toughness tool against an established ASTM standard for polymer fracture toughness, D5045, and a commonly used four-point bend method. The materials used in this study were polycarbonate and high density polyethylene. Reductions in both the production time and the variability resulting from the preparation of the specimens were addressed through the use of specially designed fixtures. The effects from the razor cut depths used in the chevron notch were compared to the fracture toughness values obtained in order to determine the effect upon the validity of the fracture toughness.
A Dialectical Approach to Studying Long-Distance Maintenance Strategies: Using both qualitative and quantitative methodology, this thesis investigates the tactics used by long-distance relational partners, the differences in use of the tactics between long-distance and proximal partners, the relationship among the maintenance tactics, and the relationship of the tactics to relational satisfaction. Seven relational maintenance strategies were identified from the investigation: affirmation, expression, high tech mediated communication, low tech mediated communication, future thought, negative disclosure, and together-time. Significant differences in the use of maintenance tactics between long-distance and proximal partners were discovered and several tactics were found to correlate with relational satisfaction for both relationship types. It is concluded that relational maintenance should be viewed from a multi-dimensional perspective that recognizes the impact relational dialectics have on relationships.
Diane Di Prima: The Muffled Voice of the Beat Generation: The Beat rejection of conventional values meant a rejection of marriage, family, and a nine-to-five job, and few women were prepared to make that kind of radical shift in a society that condemned women for behaving the way the Beats behaved. Though she has faced difficulty in getting published, Beat writer Diane Di Prima has been publishing steadily for the past forty years. Di Prima has also lived the life of a Beat, wandering the country, avoiding nine-to-five work and supporting herself with grants, teaching and poetry readings. In spite of her success and adherence to the Beat lifestyle, Di Prima has given birth to five children, all of whom she took with her in her travels. Diane Di Prima has always faced the particular challenge of gaining the acceptance of her male peers amid indifference and hatred toward her sex while not allowing these men to go unanswered.
Distribution of a Novel Gram Negative, Capsule-Forming Bacterium: A novel Gram negative, capsule-forming bacterium was previously isolated in Dr. G. Roland Vela's laboratory. The distribution of this bacterium in soils from various locations was investigated. Soil samples from 188 locations around the world were examined. Isolates of the bacterium were obtained from 50 of these soils, with 48 of the isolates found in soils from the southwestern United States and northern Mexico. This suggests that this region is the natural habitat of the bacterium. The other two isolates were obtained from Madrid, Spain and Taipei, Taiwan. None were found in soils from South America or Australia. A lack of variation in morphology and physiological properties in the isolates suggests that a homogeneous population exists, even from widespread geographical locations.
Disturbing the Peace: Disturbing the Peace is a short, 16mm sync-sound fiction film. Alone one stormy night, a woman must contend with an intruder breaking into her home. The intruder turns out to be a teenage boy. He claims to have broken in only to retrieve a family heirloom he hid there when he and his parents lived in the same house years ago. When the boy finds the heirloom, the woman begins to believe his story, and soon realizes he doesn't have a good home life. The boy asks permission to stay until the storm breaks. She agrees. Should the boy be trusted, or is he telling one lie after another? The police arrive to witness the outcome of the story.
DNA Typing of HLA-B by PCR with Primer Mixes Utilizing Sequence-Specific Primers: The aim of this study was to design a resolution typing system for the HLA-B gene. This technique involves a one-step PCR reaction utilizing genomic DNA and sequence-specific primers to determine the specificity of each allele and to produce a larger primer data base ideal for serological analysis. The application of this technique to serological analysis can improve serology detection which is currently hindered by antibody cross-reactivity and the unavailability of useful typing reagents.
The Effect of Running Speed on VO2 Kinetics in the Severe Exercise Domain: There has been an interest in the kinetics of the V02 response during exercise at various intensities. However, most studies focus on the response of submaximal intensities whereas few studies have examined V02 kinetics at severe intensities. The purpose of this study was to evaluate the effect of exercise intensity on V02 kinetics over a range of severe intensities.
Effects of Maternal Aerobic Exercise on Selected Pregnancy Outcomes in Nulliparas: This study evaluated the effects of participation in aerobic exercise on pregnancy outcomes. Pregnancy outcomes included type of delivery, length of labor, gestational age, neonatal birth weight, and maternal weight gain. The 137 nulliparas were categorized as active (N=44) or sedentary (N=93) based on self-reported aerobic exercise. Findings from this study suggest that pregnant women who were active during pregnancy were more likely to have vaginal deliveries than sedentary women. No significant differences between active and sedentary women were found in neonatal birth weight, maternal weight gain, length of labor, or gestational age.
Effects of Performance Levels of Subject Matter Experts on Job Analysis Outcomes: Much research has been undertaken to determine how Subject Matter Expert characteristics affect job analysis outcomes. The current study seeks to discover if performance levels are related to current incumbents ratings of their positions. A group of 114 corporate associates, from two administrative positions, served as Subject Matter Experts (SME) for this study. Separate job analyses for each position were conducted using the Job Analysis Task Checklist. The results for each job were analyzed to determine if SME performance levels affected job analysis outcomes. The results for both jobs showed that there were very few differences in job analysis results as a function of SME performance levels.
Elementary School Teachers' Responses to Potential Child Abuse: This study was designed to evaluate: (a) teachers' behavior when they are confronted with potential cases of child abuse and (b) the information teachers require to make accurate decisions regarding the reporting of suspected child abuse. Teachers were presented with three vignettes describing cases of varying levels of suspected maltreatment, and different amounts of additional information. They were then asked to indicate how likely they would be to report the case to Child Protective Services (CPS). It was expected that reporting behavior would increase as available information increased. The results generally did not support this hypothesis. No significant impact on reporting behavior was found when teachers were presented with either the symptom list or the legal interpretation; however, there was a trend toward an interaction with the level of abusive indications in the case. These results are discussed in the context of the need for further training.
The Emergence of a New Capitalist Ethic: Transformational Leadership and the Civil Society Movement as Emergent Paradigms Affecting Organizational and Societal Transformation: Rapid and chaotic changes in market environments have caused business organizations to modify their organizational structures and social relationships. This paper examines the change in relationship between management and employees, which is shifting from an adversarial and controlling role to facilitation and employee empowerment. This paper's research question concerns how classical sociological theory would explain power redistribution within organizations and the formation of an associative and collaborative relationship which contradicts traditional paradigms. Traditional bureaucratic and contemporary organizational forms are compared and contrasted. Organizational climate, psycho-social components of underlying assumptions and group ethics are seen to be the mechanisms impelling transformation. Organizational change is driven by an emerging secular ethic. This ethic is embodied in an applied model of leadership and examined as an ideal type. The common ethic impelling organizational change is seen to be the same as that causing social transformation in both national and international spheres.
Entering the Circle: The Only Viable Hermeneutic for a Biblical Response to Ecocrisis: A paradox exists in attempting to resolve ecocrisis: awareness of ecological concerns is growing, but the crisis continues to escalate. John Firor, a well-known scientist, suggests that to resolve the paradox and hence ecocrisis, we need an alternative definition of "human beingness"--that is, a human ontology.
Evaluation of the Use of the Bivalves Ischadium recurvum Rafinesque, 1820 and Corbicula fluminea Muller, 1774 as Biological Indicators of Relative Water Quality in Terms of Growth and Upper Temperature Tolerance: Growth of mussels under laboratory conditions was examined under various food regimes in different water types and temperatures. Growth was less than would be useful as an indicator and comparisons with field exposures were of minimal value. The effects of organophosphates on bivalves were examined via toxicity tests, tissue concentration, and by controlling exposure through the use of physical constraints. Upper temperature tolerance of both bivalve species was examined with respect to different acclimation temperatures and organophosphate exposures. Deviations from control exposures occurred at some temperatures. Copper effectively lowered the mean heat coma temperatures of C. fluminea at some concentrations, however, chlorine exposures did not alter heat coma temperature.
The Evolution, Applications, and Statistical Interpretations of DNA Typing in Forensic Science: This thesis examines the evolution, applications, and statistical interpretations of DNA typing as a tool in the field of forensic science as well as in our criminal justice system. The most controversial aspect of DNA typing involves the determination of how likely it is that two people share the same DNA profile. This involves the use of population genetics and databases of allelic frequencies as well as some assumptions about population structuring.
Examining the Relationship between Variability in Acquisition and Variability in Extinction: Using the "revealed operant" technique, variability during acquisition and extinction was examined with measures of response rate and a detailed analysis of response topography. During acquisition, subjects learned to emit four response patterns. A continuous schedule of reinforcement (CRF) for 100 repetitions was used for each pattern and a 30 min extinction phase immediately followed. One group of subjects learned the response patterns via a "trial-and-error" method. This resulted in a wide range of variability during acquisition and extinction. Only one subject emitted a substantial amount of resurgent behavior. A second group of subjects was given instructions on what keys to press to earn reinforcers. This group had less variability in acquisition and extinction and resurgent responding was prevalent.
Expectation as Narrative Strategy in Richard Wagner's Parsifal: The story of Parsifal is presented in two manners: through action and through narrative. Using the formalist theories of Vladimir Propp, the overall narrative is articulated in three narrative episodes. This thesis interprets the structure of narrative episodes in Parsifal on the basis of expectation. Propp's theory of functions provides labels for an interpretive analysis. Levi-Strauss' reconstruction of Propp's functions into paired structures identifies key points in the drama as moments of "functional" saturation. This "functional" saturation coincides with Wagner's practice of Leitmotivic saturation. The semiotic theories of Charles Sanders Peirce, specifically his notion of sign, clarify the dense accumulation of meanings accrued by the Leitmotifs. Finally, Parsifal, as a "quest" for the unobtainable object, fits into the matrix of desire as formulated in the theories of Jacques Lacan.
Expendable Creation: Classical Pentecostalism and Environmental Disregard: Whereas the ecological crisis has elicited a response from many quarters of American Christianity, classical (or denominational) Pentecostals have expressed almost no concern about environmental problems. The reasons for their disregard of the environment lie in the Pentecostal worldview which finds expression in their: (1) tradition; (2) view of human and natural history; (3) common theological beliefs; and (4) scriptural interpretation. All these aspects of Pentecostalism emphasize and value the supernatural--conversely viewing nature as subordinate, dependent and temporary. Therefore, the ecocrisis is not problematic because, for Pentecostals, the natural environment is: of only relative value; must serve the divine plan; and will soon be destroyed and replaced. Furthermore, Pentecostals are likely to continue their environmental disregard, since the supernaturalism which spawns it is key to Pentecostal identity.
Factors that Influence Men to Coach Women's NCAA Division II Basketball: This study identified factors that influenced men to coach women's basketball. The CCFQ, designed to determine relative importance of each of nine factors in career selection, was completed by 78 male head coaches of women's NCAA II basketball. Data was analyzed using univariate analysis with repeated measures, t-tests, and ANOVA. These coaches indicated fulfill need for competition, help female athletes reach full potential, and serve as role model as significant influences. Moderate influences included personal attributes of athletes, job attributes, and career advancement. Job availability, belief in own success, and income were not considered influential in career selection. Few differences were indicated between demographic sub-groups on any factor. Factors associated with well being of athletes had the greatest influence.
Fanny Mendelssohn Hensel : A Bridge between Felix Mendelssohn and Johannes Brahms: This thesis is a study of four compositions written by Fanny Mendelssohn Hensel, older sister of Felix Mendelssohn. Her music is compared with four pieces composed by Felix. This study shows that Fanny was a gifted and creative composer, even surpassing Felix and predating Brahms with her compositional ideas and progressive uses of harmony. Despite her excellent education and recognition among those who knew her well, she did not publicize her talent in any way because of pressure from her father, Abraham, and Felix to stay within the prescribed societal confines of wife and mother.
Fracture Toughness Testing of Plastics under Various Environmental Conditions: The primary objective of this study is to test the applicability to plastics of a fracture toughness testing tool developed for metals. The intent is to study pre-test conditioning of several plastic materials and the effect of the depth of the razor notch cut in the chevron notched fracture toughness test specimens. The study includes the careful preparation of samples followed by conditioning in various environments. Samples were subjected to laboratory air for a specific duration or to a controlled temperature-humidity condition as per the ASTM D1870. Some of the samples were subjected to vacuum conditioning under standard test specifications. Testing was conducted using the conventional three-point bend test as per ASTM D5045-95. ASTM E1304, which sets a standard for short rod and bar testing of metals and ceramics provides some basis for conducting chevron notched four-point bend tests to duplicate the toughness tool. Correlation of these results with the ASTM test samples is determined. The four-point bend test involves less specimen machining as well as time to perform the fracture toughness tests. This study of fracture toughness testing has potential for quality control as well as the fracture property determination.
The Full Armor of God: The Full Armor of God is a musical composition based on the apostle Paul's comparison in Ephesians 6:10-20 between armor for physical combat and armor for spiritual warfare. The instrumentation consists of the following: oboe/English horn, bassoon, two violins, viola, cello, and bass. Texts on Roman armor as well as commentaries and sermons on the scriptures were consulted for the basis of the musical materials. The piece combines imagery and historical associations with abstract renderings of both the physical and the spiritual.
The Horn at the Paris Conservatoire and its Morceaux de Concours to 1996: A work concerning the history of the Paris Conservatoire and music education in France. Follows the development of the horn and its correlation with the French school of horn playing. Includes biographic information on the horn professors of the Conservatoire through 1997, as well as a comprehensive list of the morceaux de concours for horn, 1795-1996.
Increasing Differentiation on Vocational Assessments among Gifted High School Students: Multipotentiality makes career counseling with gifted students difficult. High-flat vocational profiles give the impression that gifted students can develop a wide range of abilities to an equally high level. High-flat vocational profiles may be due to assessments that consider abilities and disregard interests and values, and ceiling effects from the use of age-appropriate, rather than cognitively-appropriate measures. Subjects included 170 gifted students from a residential, early college entrance program (M=15.9 yrs., SD=.361). Subjects completed the Scholastic Aptitude Test, Self-Directed Search, and Study of Values. McNemar's Test of Correlated Proportions shows the proportion of multipotential profiles decreases significantly when cognitively-appropriate measures of interests and values are considered, in addition to abilities. Pearson Chi-square shows no ethnic differences.
Intelligent Discontent, Agitation, and Progress: A Time-Series Analysis of National Revolts in Central America 1960-1982: Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua have all experienced significant social, economic, and political changes during the 1960s, 1970s, and 1980s. Guatemala, El Salvador, and Nicaragua experienced violent national revolts, while Costa Rica and Honduras did not. I tested a process theory that endeavored to account for the origins and intensity of national revolts in Central America. The analysis was formulated in a most-similar-systems (MSS) design. Pooled cross-sectional time-series regression techniques were employed in order to conform with the MSS variation-finding strategy. The findings supported the conclusion that armed attacks against the state were not random occurrences, but rather, that they may have arisen in response to certain economic and political conditions.
Inventions, Dreams, Imitations: Eight short selections of fiction. "Inventions" consists of two invented creation myths. The three stories in "Dreams" are fantasy tales set in a common dream-world. The selections in "Imitations" are neither fantasy nor science fiction: "Time's Tapering Blade" is an experiment in form; "The Wake" concerns a group of friends dealing with a death; and "Janie, Hold the Light" is based on stories from the author's family about Christmas during the depression of the 1930's.
An Investigation of the Influence of Evaluator Background on Appraisals of a Music Lesson Using the Texas Teacher Appraisal System: This study's purpose was to investigate the differences in scores and written comments given by two appraisal groups in their evaluation of a music teacher using the Texas Teacher Appraisal System (TTAS). One appraiser group had musical training while the other group specialized in other subjects. Analyses of both group's appraisal scores showed no significant differences. An examination of the written comments revealed that both appraisal groups focused on the same aspects of the lesson and used similar vocabulary. The TTAS instrument was a consistent measure of generic teacher behaviors in the music lesson, but it did not measure specific music teaching behaviors or encourage suggestions for improving musical instruction.
Investigation of Ultratrace Metallic and Organic Contaminants in Semiconductor Processing Environments: Detection of ultratrace levels of metallic ion impurities in hydrofluoric acid solutions and alkaline hydrogen peroxide solution was demonstrated using a silicon-based sensing electrode. The sensor's operation principle is based on direct measurements of the silicon open-circuit potential shift generated by the interaction between metallic ions and the silicon-based sensing surface. The new sensor can have practical applications in the on-line monitoring of microelectronic chemical processing. The detection of Ag+ content in KODAK waste water was carried out successfully by this novel sensor. Trace levels of organic impurities in the hydrofluoric acid solutions and in the cleanroom air were characterized by multiple internal reflection infrared spectroscopy (MIRIS) using an organics probe prepared directly from a regular silicon wafer.
Iranian Access Television of Dallas: Cultural Issues, Preservation, and Community Formation: This study focused on the televisual and cultural practices of Iranians via public access television in Dallas, Texas. It includes analysis of format and content. It combines demographic, structural, and statistical information with a culturalist and interpretive viewpoint in examining the efforts of Iranians, via access television programs, in preserving their culture and the formation of a coherent and active community in the Dallas/Fort Worth Metroplex.
Korean Students' Perceptions of the Effectiveness of their Internship Experiences in the Hospitality Industry in Korea: This research study assessed Korean students' perceptions and overall satisfaction levels regarding the effectiveness of their hospitality internship experiences. Relationships with demographic characteristics were identified. The sample was comprised of 74 senior-level university students enrolled in hospitality and/or tourism management programs who were completing an internship in Korea. Generally, students exhibited low agreement levels on the internship program aspects being investigated. Previous work experience was the most common factor influencing students' perceptions of their internship experiences. Agreement levels increased with length of prior work experience. Type of internship workplace, expectation of an employment offer, age and gender were found to influence students' perceptions of the internship experiences.
Life History of Mayatrichia ponta Ross (Trichoptera: Hydroptilidae) in Honey Creek, Turner Falls Park, Oklahoma: The life history and ontogenetic microhabitat change of Mayatrichia ponta Ross were investigated in Honey Creek, Turner Falls Park, Murray Co., Oklahoma, U.S.A. from August 1994 to August 1995. The shape of larval cases changed from a small cone to a cylinder. M. ponta had an asynchronous multivoltine life history with considerable cohort and generation overlap; five generations were estimated. The development rate was reduced in winter. The winter generations of M. ponta had wider head capsule widths (136-165 μm) than summer generations (121-145 μm). The sex ratio of adults was 1.43 ♂ : 1 ♀. Fecundity ranged from 46 to 150 eggs/female. Fifth instar larvae and pupae aggregated on the bottom side of substrates. Early instars were distributed evenly on all sides of substrates. General patterns of ontogenetic microhabitat shift in aquatic insects are categorized as flow mediated, flow independent, and population interactions and other resources mediated.
Maelstrom: the Last Coyote Tale: It is a dark future, where corporations have taken the place of governmental bodies, and Earth is a myth, forgotten in the reconstruction after the Second Dark Age. One man--a clone--investigates a murder [that] leads him deep into a spirit quest of his own that will answer the questions of Man's heritage as well as his own identity. This story is a science fiction, but it is similar in structure to a Coyote tale and involves quite a bit of Navajo mythology. The use of Native American imagery is not an attempt to capitalize on another culture, but rather to study the culture and use allegorical elements that transcend many cultures. It must also be noted that non-Native American writers wrote all texts available on the subject. This fact should be taken into consideration by the reader.
Mixed Alkyllithim/Lithium Alkoxide Aggregates with Less Sterically Crowded Alkyl Groups: Mixed alkyllithium / lithium alkoxide aggregates in the form (RLi)n(ROLi)m were formed by addition of corresponding alcohol compounds at different Li/O ratios. Variable temperature 13C and 6Li NMR spectroscopy were used to verify the formation of the mixed aggregates and to study their behavior in hydrocarbon solution. Spectra for the lithium n-propoxide / n-propyllithium and iso-butyllithium / lithium iso-butoxide systems each indicated at least one mixed aggregate.
Mobile Order Theory as Applied to Polycyclic Aromatic Heterocycles: Experimental mole fraction solubilities of benzil, thianthrene, trans-stilbene, thioxanthen-9-one, diphenyl sulfone and dibenzothiophene sulfone are determined in pure noncomplexing and complexing solvents. Predicted solubility values are calculated for benzil, thianthrene, trans-stilbene and thioxanthen-9-one using expressions derived from Mobile Order theory. Large deviations between experimental and predicted solubilities in alcohol solvents exist, therefore optimized solute - solvent association constants are determined. Previously measured thianthrene solubilities in five binary alkane + cyclohexane solvent mixtures are compared with values predicted from Mobile Order theory using the measured solubility in each of the pure solvents as input parameters. The experimental mole fraction solubility of benzil in eight binary alcohol + 1-octanol solvent mixtures are also measured and compared with predicted values.
Mobiles: Mobiles is a composition for an ensemble consisting of 12 instruments. The piece, in one movement, incorporates intuition, chance, and twelve tone techniques and reflects the relationship between motion and rest or tension and release. The structure is modeled according to principles of growth and decay, starting off slowly, building, and then dying away. Much of the material is inspired by mental images invoked from modern theories concerning chaos. Mobiles' character stems from the principal use of two motives, the chaos motif and the echo motif. Primarily, the chaos motif is representative of a state of motion while the echo motif represents a state of rest. Mobile architecture is usually characteristic of symmetry, balance, and proportion, but because of uncertainty in a natural environment, this proportion often falls short of a perfect symmetrical balance as in the case of a crystal or a fractal design. It is this kind of architecture that Mobiles portrays in its form and developmental process.
