The Function-Altering Effects of Contingency-Specifying Stimuli

Description: Three children between the ages of 3 and 3 1/2 were asked to choose a colored object from an array of 5 colors in a baseline condition. After color preferences were established, stickers, small toys and praise were made contingent on choosing the least preferred color. After the first experimental condition resulted in consistent choosing of the least preferred color, a second experimental condition was implemented. At the beginning of each session a contingency-specifying stimulus (CSS) was presented, each CSS specifying a different color to be selected. Both contingency-shaping and CSS presentation resulted in stimulus control over responding. However, CSS presentation resulted in immediate redistributions of behavioral units across CSS sessions.

Kinetic Studies of the Reactions of Cl and Br with Silane and Trimethylsilane

Description: The temperature dependence of the reactions of halogen atoms Cl and Br with SiH4 and (CH3)3SiH have been investigated with the flash photolysis-resonance fluorescence technique. CCI4 and CH2Br2 were used as precursors to produce Cl and Br atoms, respectively. Experiments gave {k(Cl + SiH4) (295 - 472 K)} = (1.56 +0.11) x 10-1 exp[(2.0 + 0.2) kJ mol'/RT] cm3 s4, {k(Br + SiH4)(295 - 575 K)} = (9.0 + 1.5) x 10-" exp[-(17.0 + 0.6) Id mol'/RT] cm3 s', {k(Cl + (CH3)3SiH)(295 - 468 K)} = (1.24 0.35) x 104 exp[(1.3 + 0.8) Id mol4/RT] cm3 s', and {k(Br + (CH3)3SiH)(295 - 456 K)} = (7.6 + 3.3) x 1010 exp[-(28.4 + 1.3) Id mol'/RT] cm3 s'. The results were compared with values from earlier work.

On Viewing Press Releases of the Texas State AFL-CIO as Rhetorical Genre

Description: Previous scholarship on labor rhetoric has concentrated on the impact of declining union membership and contemporary activist strategies on the part of unions. The press release is a common form of communication that organized labor employs in order to reach its publics. This study explores the press releases of the Texas State AFL-CIO to determine to what extent this level of labor discourse meets the criteria of a rhetorical genre. This study employs the methodology for generic criticism laid out by Foss for identifying genres. The study concludes that a genre of labor rhetoric exists and that the genre was used extensively to promote the Texas State AFL-CIO as a socially-conscious and politically motivated organization.

The Effectiveness of an Exercise Intervention Program in Reducing Cardiovascular Risk Among Employees in a University Setting

Description: Nine physiological measures were evaluated pre- to post-intervention on subjects participating in a university health promotion program over a seven-month period. Frequency of program attendance and choice of activity were also assessed. Of the 88 employees initially screened, most of the subjects were staff members (n=82, 93%),with a majority being female (n=68, 77%). Significant differences in physiological measures were found pre- to post-intervention between "higher" and "lower" cardiovascular risk participants, primarily due to the type of activity chosen. .The results indicate that health promotion programs at a university are an effective way to have an impact on employees in reducing their cardiovascular risk factors.

The Chaconne Bass as a Musical Topos in Mozart's Fantasia Music

Description: This thesis provides evidence that a particular "topos" from the high Baroque's exalted style, the so-called chaconne bass, made a profound impact on a considerable body of Mozart's compositions from the last ten years of his life in Vienna. After identifying the topos in the first chapter, a detailed study in chapter two shows how Mozart's faith in the extraordinary emotional power carried by this topos was enough for him to work it into all of the completed keyboard fantasias. Chapter three illustrates that an understanding of the chaconne bass and its unmistakable association with the fantasia style can shed new light on three of Mozart's most enigmatic compositions from his final period, K. 465, K. 491, and K. 527.

The Reproductive Consequences of Carriers of Methylenebisacrylamide-Induced Balanced Reciprocal Translocations in Mus Musculus

Description: N,N'-methylenebisacrylamide (MBA) was studied because of its effectiveness in inducing heritable translocations in germ cells of male mice. The health impact of translocations was studied through anatomical analysis of the progeny of semisterile translocation carriers. As expected, the semisterility of translocation carriers resulted primarily from embryonic death during periimplantation stages due to unbalanced chromosome sperm segregants. Among conceptuses that survived to mid- and late-gestation stages, there was an increased incidence of developmental anomalies including fetal death and phenotypic defects. These abnormalities are associated with unbalanced chromosome complements that allow survival to the later stages of development.

Alaskan Native Social Integration and Academic Achievement

Description: The variables communication skills, state anxiety, communication apprehension, and level of integration are studied in relation to the assimilation of Alaskan Natives into a western-culture university. Specifically, the differences in communication skills between the two cultures and their effects on course grades are addressed. Results of the statistical analyses (ANOVA, MANOVA, discriminant function analysis, multiple regression) were not significant, most likely due to the small Alaskan Native sample size. The most significant relationship appeared between situational communication apprehension and the ethnicity of the interaction partner. Other results were directional, indicating that variables may be related to assimilation of Native students into a western university environment. Further research and replication is warranted, using an adequate sample of Alaskan Natives.

Authorship, Content and Intention in the West Saxon Consolation of Philosophy

Description: Boethius, a late Roman philosopher, composed his last work, De Consolatione Philosophiae, while in prison. His final effort crowned a lifetime of philosophical achievement, and the work was influential throughout the Middle Ages. Frequently translated, the Consolation was one of the books which was chosen by Alfred, a ninth century Anglo-Saxon king, for use in the rebuilding of his kingdom after the Danish invasions. Although intended for an audience which was heavily influenced by a lively pagan tradition, the book was re-interpreted during the Carolingian period to conform to a strict Christian standard. Alfred's own interpretation is indicative of this amalgamation of ancient learning in the milieu of an emerging European culture, as well as his own pragmatic personality.

Environmental Correlates to Genetic Variation in the Coral Reef Fish, Thalassoma bifasciatum

Description: Genetic variation was examined in bluehead wrasse, Thalassoma bifasciatum, populations along the Florida Keys. Interpretion of mean heterozygosity (H), percent polymorphic loci per population (P), genetic similarity, and F and G statistics demonstrated a clear division of wrasse populations into "northern" and "southern" groups. Correlation and cluster analyses indicated the six reefs can be grouped in a similar fashion based on genetic and environmental data. The conclusion from this analysis of wrasse populations in the Florida Keys is that substantial population subdivision occurs in response to differing selective pressures created by heterogeneous environments.

Synthesis, Structure, and Solution Dynamics of Co₄(CO)₈(dmpe)(mu₄-PPh)₂

Description: Reaction of the tetracobalt cluster Co4(CO)10(t 4-PPh)2 with 1,2-bis(dimethylphosphino)ethane (dmpe) affords the bis-substituted cluster Co4(CO)8(dmpe)(t 4-PPh)2. The bidentate dmpe ligand is shown to bind to the cluster in a chelating fashion by IR, NMR, and X-ray diffractions analyses. The fluxional nature of the ancillary carbonyl groups has been studied by variable temperature 13C NMR measurements which reveal two distinct carbonyl scrambling pathways. The stability of the phosphine-ligated cluster has been examined using in situ Cylindrical Internal Reflection (CIR) Spectroscopy. The effect of the dmpe ligand on the cluster polyhedron will be discussed with respect to the observed crystallographic and spectroscopic results

The Effect of Cognitive Development and Premarital Sexual Permissiveness on Adolescent Pregnancy

Description: A literature review revealed 15 variables as commonly studied as associated with adolescent pregnancy. The research showed conflicting results in many of these areas. Twenty-one pregnant and 20 non-pregnant adolescents were tested using the Arlin Test of Formal Reasoning (ATFR) and the Reiss's Premarital Sexual Permissiveness Scale. Pregnant participants were expected to score lower than non-pregnant participants on the ATFR; and, the low permissives (based on responses to the Reiss's Premarital Sexual Permissiveness Scale) were expected to score higher than high permissives on the ATFR. However, the results did not support the hypotheses. Several areas were examined for exploratory purposes. There was a significant difference between high permissives and low permissives for parent/peer orientation for sexual behavior attitudes. Additional exploratory demographic information was collected using a General Information Questionnaire.

Assessment of Computer Uses in Texas University and College Foodservice

Description: The purposes of this study were. to identify current uses of computers by university foodservice operations and to determine if there.are any differences in computer use among university foodservice operations. The twelve university foodservice directors who responded to the research questionnaire varied significantly in their computer usage and computer characteristics. Institutions serving more than 1,000 meals per day represented 91% of the sample using computers. Chi Square analysis found a significant use of menu-costing programs. The computers were used more than six hours a day by 75% of the sample. The.problems relating to hardware and software selection indicate a lack of assessment of operational needs for foodservice operations. Guidelines to assist foodservice directors in computerization are needed.

Genetic Variation in a Population of the Plains Woodrat Neotoma micropus

Description: Neotoma micropus from Jack County, Texas, were studied over a 9-month period. Loci from blood and saliva were used to determine genetic variation within the population. Deviations from Hardy-Weinberg equilibrium were found at one locus. The average temporal F over all seven loci was 0.040. Genetic structuring was subtle, fluctuated on a seasonal basis, and was due to differential migration or predation on genotypes. Heterozygotes tended to move more than homozygotes, and a greater proportion of heterozygotes were lost from the population during each season. Genetic variation was maintained in the population by immigrant individuals. This differential in dispersal of genotypes fits current models of reorganization within the genome of populations.

Sex Role Types and Psychological Adjustment: Androgyny, Masculinity, or Self-Esteem

Description: Since the advent of the Bem Sex Role Inventory (Bem, 1974) two models, the Androgyny and Masculinity model, have been advanced to explain the sex role literature. This study attempts to rectify several methodological issues by experimentally controlling for the effects of self-esteem and using a quartile-split procedure for sex role type assignment. Two experiments were conducted to evaluate interpersonal problem solving ability among sex role types and to compare the predictions of the Androgyny model and the Masculinity model. The results of both experiments implicate the crucial role of self-esteem in sex role research. Self-esteem, rather than sex role type, appears to be more predictive of adequate psychological adjustment.

Variations on a Theme: The Monomyth in John Fowles's The French Lieutenant's Woman

Description: This study analyzes the development of the major characters in Fowles's novel - Charles, Sarah, and Sam - in terms of the heroic quest motif. Using the basic pattern of the heroic quest, the monomyth, that Joseph Campbell sets forth in his The Hero with a Thousand Faces, I attempt to show that Fowles's novel may best be understood as the story of three separate heroic quests whose paths cross rather than as the story of a single hero or heroine. This reading seems to account best for all elements of the novel and to explain best the final positions of the characters in question as well as providing a rich appreciation of the novel's wealth of imagery.

A Study of Three Related Works by Michael Tippett: A Child of Our Time, The Vision of Saint Augustine, The Mask of Time

Description: Three works by Tippett stand together among his compositions because of their similarity of subject and performance medium. All are large works for soloists, chorus and orchestra, on meditative librettos, and intended for unstaged presentation. Only A Child of Our Time is given the genre designation "oratorio" by Tippett. An in-depth analysis of these works and the model for A Child of Our Time, Handel's Messiah, reveals that though they neither present religious subjects nor, in the case of The Vision of Saint Augustine and The Mask of Time, exhibit traditional formal divisions associated with oratorio, Tippett's works do indeed belong to the oratorio repertoire of the twentieth century.

Kate Chopin's The Awakening: Narcissism in the Suicide and Sexuality of Edna Pontellier

Description: The central figure in The Awakening, Edna Pontellier, is shown in this thesis to pursue a narcissistic flight from existential reality. Following a review of contemporary criticism, Edna Pontellier's narcissism is discussed in connection with her sexuality and suicide. Sources cited range from biographies of Kate Chopin to scholarly articles to the works of modern psychologists. The emphasis throughout the thesis is on the wealth of interpretations that currently exist on The Awakening as well as the potential for further -study and interpretation in the future. Rather than viewing The Awakening as a purely feministic novel, it is stressed that The Awakening can transcend such categorization and be appreciated on many levels.

Elemental Analysis of Brainstem in Victims of Sudden Infant Death Syndrome

Description: A brainstem-related abnormality in respiratory control appears to be one of the most compelling mechanisms for sudden infant death syndrome (SIDS). The elements calcium, copper, iron, potassium, magnesium, sodium, phosphorus, sulfur, and zinc were analyzed by inductively coupled plasma atomic emission spectroscopy in the brainstem of 30 infants who died from SIDS and 10 infants who died from other causes (control). No differences were found between SIDS and control for any element except for more calcium in the SIDS group. A multivariate analysis of the data failed to group the majority of SIDS and control subjects in different clusters. Further research is required to determine the biological significance of the higher calcium found in the SIDS group.,

Trace Elemental Analysis of Ashes in the Combustion of the Binder Enhanced d-RDF by Inductively Coupled Plasma Atomic Emission Spectroscopy

Description: Incineration is an attractive solution to the problems of disposing of municipal solid wastes and supplying energy. Because up to 25 percent of the waste in refuse-derived-fuel systems is ash, the physical and chemical characteristics of ash become more and more important for its potential impacts and methods suitable for their disposal. Trace elements concentration in ash is of great interest because of its relationship to regulatory criteria under the Resource Conservation and Recovery Act (RCRA) regarding toxicity and hazards. The applications of a microwave oven sample dissolution method has been tested on a variety of standard reference materials, with reproducible and accurate results. Fourteen trace elements, As, Ba, Be, Cd, Cr, Cu, Hg, Ni, Pb, Sb, Se, Tl, V, and Zn, from the dissolved ash samples were determined by inductively coupled plasma atomic emission spectrometry.

An Analysis of Propaganda in the Yellow Rain Controversy

Description: The use of arguments containing increasingly technical materials has grown significantly in the recent years. Specifically, arguments that are used to justify military expenditures or to allege violations of international agreements are becoming more sophisticated. This study examines the dissemination and use of technical argument in claims made by the United States government that the Soviet Union violated chemical and biological treaties in Southeast Asia and Afghanistan. This study employs the Jowett-O'Donnell method for analyzing propaganda to determine the extent and effectiveness of the government's claims. The study concludes that propaganda was used extensively by the government in order to justify new weapons programs and that the propaganda campaign was effective because of the technological orientation of its claims.

Ground Reaction Forces and Ankle and Knee Moments During Rope Skipping

Description: Ground reaction force (GRF) data collected and synchronized with film data to determine peak GRF and calculate moments about ankle and knee during rope skipping. Two, five minute conditions were analyzed for 10 subjects. Condition 1 was set rate and style. Condition 2 was subjects' own rate and style. Means and standard deviations were reported for peak GRF, ankle and knee moments. One way ANOVAs reported no significant difference between conditions for variables measured. Efficiency and nature of well phased impacts during rope skipping may be determined by combination of GRF, similarities in magnitude and direction of joint moments, and sequencing of segmental movements. Technique and even distribution of force across articulations appear more important than magnitudes of force produced by given styles.

Development of Biographical Predictors of Cashier Turnover at a Convenience Store Chain

Description: Subjects, 432 convenience store cashiers, were divided into long-tenure and short-tenure groups. Chi-square analysis of application blank information for a weighting sample drawn from both groups revealed two items which significantly (p < .05) differentiated between the long tenure and short-tenure groups: number of previous jobs and full-time/part-time preference. Response weights were computed for these two items and used to calculate composite scores for the remaining holdout sample. A significant reduction in turnover would have occurred at the highest composite score level, if used as a hiring cut off. Results were tempered by several considerations, including a high percentage of false negatives and an insignificant linear relationship between composite scores and tenure.

Comparability of WPPSI-R and Slosson Tests as a Function of the Child's Ethnicity

Description: The purpose of this study was two-fold. First, this study compared the performance of children on the WPPSI-R with their performance on the Slosson Intelligence Test. Secondly, this study explored the comparability of minority and non-minority students' scores on the WPPSI-R. Seventy five children between 3 and 7 years of age were administered the WPPSI-R and Slosson. Of this sample, 25 children were White, 25 children were Black, and 25 children were Mexican American. Low, but significant correlations were found between WPPSI-R and Slosson scores. The Vocabulary subscale of the WPPSI-R correlated highest, while the Geometric Design subscale correlated the lowest with the Slosson test scores. Further analyses indicated that White children obtained significantly higher scores on the WPPSI-R than both Black and Mexican American children.
