This research surveys ideology and iconology in the presentation of the autobiographical and biographical female nude as envisioned by American women artists in the painting, drawing and printmaking media from 1969 to 1983. Contemporary dialogue by critics, artists and feminists on the definition of feminine content led to the articulation of the undraped nude torso as the central icon of the study. This static icon was pushed through a variety of styles into multi subtleties of iconology. The female nude by women artists is autobiographical even in biography emphasizing self-identification and authenticity. General constraints were placed on the survey the definability or explicit articulation of the female torso as opposed to suggestive imagery, the time frame in which the nude was created, and the chosen media for study. Art historical methodology was employed to descriptively examine image and intent of the nude presentations in references through time as well as visual traditions of symbology. This survey began at the turn of the century for historical background to emphasize the greater proliferation of the nude from 1969 to 1983. There were limitations specifically associated with the earlier time frame (1900-1969)--the lack of art educational opportunities for the female student, the socio-political …

In this dissertation, we describe the automorphism groups for the strong Bruhat orders A_n-1, B_n, and D_n. In particular, the automorphism group of A_n-1 for n ≥ 3 is isomorphic to the dihedral group of order eight, D_4; the automorphism group of B_n for n ≥ 3 is isomorphic to C_2 x C_2 where C_2 is the cyclic group of order two; the automorphism group of D_n for n > 5 and n even is isomorphic to C_2 x C_2 x C_2; and the automorphism group of D_n for n ≥ 5 and n odd is isomorphic to the dihedral group D_4.

British musical style changed dramatically after 1880 primarily due to factors which may be subsumed under the general heading of nationalism. This change from an essentially Germanic style has been termed the British musical renaissance by many writers on the subject. Within this new musical language, several distinctive substyles arose. One of these, British pastoral style, has been alluded to by Frank Howes and others, but these allusions do not contribute to an understanding of the works purportedly belonging to that style. It is the purpose of this study to define British pastoral style and examine its relation to the British musical renaissance. The method employed for defining style will be that of Jan LaRue's as described in his Guidelines for Style Analysis. What is British pastoral style? Judging from the literature, British pastoral style is a type of British music written between 1900 and 1950 which evokes pastoral images, especially those associated with the British landscape. A stylistic analysis of selected works will define British pastoral style through enumeration and discussion of the style's musical constituents. A more refined definition of British pastoral style is achieved by an in-depth analysis of E. J. Moeran's Fantasy Quartet, which represents a …

The purpose of this research is to study and improve decision accuracy in the real world. Spot price prediction of petroleum products, in a budgeting context, is the task chosen to study prediction accuracy. Prediction accuracy of executives in a multinational oil company is examined. The Brunswik Lens Model framework is used to evaluate prediction accuracy. Predictions of the individuals, the composite group (mathematical average of the individuals), the interacting group, and the environmental model were compared. Predictions of the individuals were obtained through a laboratory experiment in which experts were used as subjects. The subjects were required to make spot price predictions for two petroleum products. Eight predictor variables that were actually used by the subjects in real-world predictions were elicited through an interview process. Data for a 15 month period were used to construct 31 cases for each of the two products. Prediction accuracy was evaluated by comparing predictions with the actual spot prices. Predictions of the composite group were obtained by averaging the predictions of the individuals. Interacting group predictions were obtained ex post from the company's records. The study found the interacting group to be the least accurate. The implication of this finding is that even …

In Capriccio. Richard Strauss and Clemens Krauss examine the very nature of opera with the core of their thesis being the relationship of words and music. A work that is, in essence, an extended discussion poses two problems to the composer and librettist: how to sustain the argument of the thesis without losing the attention of the audience, and how to prevent a conversational opera from sounding like endless recitative. Strauss and Krauss manage to present their case without having to resort to an actual discussion for the duration of the opera. Their characters are engaging, identifiable human beings who are also allegorical figures. Their participation in the stage action sustains the argument of the thesis even when the dialogue itself addresses other subjects. The players symbolize various facets of opera, theatre, and the public with all of them, principal and secondary characters, being sharply etched. The little stage action that Capriccio does contain is carefully paced and closely coordinated with the presentation of the work's thesis. The octets, similar in dramatic function to the central finale of a Mozart opera buffa, provide the climax of the stage action and come soon after the Fugal Debate, the centerpiece of the …

Absolute K-shell x-ray cross sections and Auger-electron cross sections are measured for carbon for 0.6 to 2.0 MeV proton incident on CH₄, n-C₄H₁₀ (n-Butane), i-C₄H₁₀ (isobutane), C₆H₆ (Benzene), C₂H₂ (Acetylene), CO and CO₂. Carbon K-shell fluorescence yields are calculated from the measurements of x-ray and Auger-electron cross sections. X-ray cross sections are measured using a variable geometry end window proportional counter. An alternate method is described for the measurement of the transmission of the proportional counter window. Auger electrons are detected by using a constant transmission energy Π/4 parallel pi ate electrostatic analyzer. Absolute carbon K-shell x-ray cross sections for CH₄ are compared to the known results of Khan et al. (1965). Auger-electron cross sections for proton impact on CH₄ are compared to the known experimental values of RΦdbro et al. (1979), and to the theoretical predictions of the first Born and ECPSSR. The data is in good agreement with both the first Born and ECPSSR, and within our experimental uncertainties with the measurements of RΦdbro et al. The x-ray cross sections, Auger-electron cross sections and fluorescence yields are plotted as a function of the Pauling charge, and show significant variations. These changes in the x-ray cross sections are compared …

High Performance Liquid Chromatography (HPLC) was used to investigate the utility of this technique for the analytical and preparative separation of components of aquatic fulvic acids (FA). Three modes of HPLC namely adsorption, anion exchange and reversed phase were evaluated. Aquatic fulvic acids were either extracted from surface water and sediment samples collected from the Southwest of the U.S., or were provided in a high purity form from the USGS. On the adsorption mode, a major fraction of aquatic fulvic acid was isolated on a semipreparative scale and subjected to Carbon-13 NMR and FAB Mass Spectroscopy. Results indicated that (1) The analyzed fraction of fulvic acid contains more aliphatic than aromatic moieties; (2) Methoxy, carboxylic acids, and esters are well-defined moieties of the macromolecule; (3) Phenolic components of the macromolecules were not detected in the Carbon-13 NMR spectrum possibly because of the presence of stable free radicals. Results of the anion exchange mode have shown that at least three types of acidic functionalities in aquatic fulvic acid can be separated. Results also indicated that aquatic fulvic acid can be progressively fractionated by using subsequent modes of HPLC. Results of reversed phase mode have shown that (1) The fractionation of aquatic …

A typology of marital dyads derived from Kelly's (1955) Personal Construct Psychology was used to investigate the communicative behaviors of married companions. Four groups based on Kelly's Commonality (dyadic similarity) and Sociality (dyadic understanding) corollaries were contrasted: similar-understanding, dissimilar-understanding, similar-misunderstanding, and dissimilar-misunderstanding couples. It was expected that dyadic understanding would contribute more to self-disclosure, cooperative involvement, and marital satisfaction than dyadic similarity. Furthermore, it was anticipated that couples high in understanding and low in similarity would represent optimally functioning couples, as evidenced by disclosure, satisfaction, and involvement with each other. Sixty-three married couples who had known each other at least two years completed questionnaire items assessing demographic variables, marital satisfaction (Dyadic Adjustment Scale) and self-reported communication behaviors (Partner Communication Inventory, Dyadic Disclosure Inventory). Each spouse also completed an 8 X 8 Repertory Grid and predicted the mate's responses on the Rep Grid. Subjects then participated in three different audio-taped discussion tasks (an informal conversation, a consensus decision-making task, and a role-played conflict-resolution scene) which were rated for avoidant, competitive, and cooperative responses, as well as overall self-disclosure. Although understanding facilitated disclosure in conflict situations and similarity fostered marital satisfaction, communicative behaviors generally reflected the joint influence of both similarity and …

The purpose of this study was to compare the achievement mean test scores in Technical Drawing of students enrolled for the NCE (Technical) program at the College of Science and Technology, Kaduna polytechnic, Kaduna, Nigeria. Test score means were compared between direct and remedial (preparatory) entry students and secondly among type of high school attended. Data were collected directly from students' permanent records. Two major hypotheses with three sub-hypotheses for each were tested. The first major hypothesis compared direct and remedial entry students. The second major hypothesis compared among three types of high schools attended. The One Way Analysis of variance (ANOVA) was used to analyze the data. The Duncan Multiple Comparison Test was also applied on the second major hypothesis. Both hypotheses I and II were retained at the .05 level of significance. However, hypothesis I was rejected at the .01 level of significance because the remedial entry students were found to have higher mean test scores than the direct entry students. Findings for hypothesis II indicated no significant difference among type of high school attended. It was recommended that selection for admissions for both the remedial and direct enrollments should not be based only on type of high …

This study is a comparison of four treatments involving education and imagery relaxation for the amelioration of dysmenorrhea. Treatment was presented to 76 subjects by videotape during a one-hour session. A six month follow-up was performed using one of the original instruments, the Symptom Severity Scale (Cox & Meyer, 1978) and a questionnaire designed for the study. Analysis of the test instruments indicated a significant treatment effect for the educational group. The second most effective treatment was a combined treatment utilizing imagery relaxation and education, although this group did not produce significant results. The no-treatment control group was more effective in diminishing symptoms than the fourth group, imagery relaxation alone. The lack of effectiveness of the imagery relaxation treatment was hypothesized to be due to lack of reinforcement of the technique. The educational treatment modality offered the individual an opportunity to learn about many different etiological facets of dysmenorrhea, including biological, learning, and cognitive factors. The presentation also introduced the individual to several different treatment modalities in order to provide an armamentarium of effective methods for diminishing or eliminating dysmenorrhea. These results suggest that there is a need for education about dysmenorrhea before menarche, in order to prepare, prevent, treat, …

The purpose of this study was to determine the effectiveness of a direct instruction model as a means of enhancing secondary students' schema for expository text. Subjects were seventh- and tenth-grade students in regular reading and English classes in an suburban school district. Students were pre- and posttested on four measures: attitude toward expository text, independent reading comprehension and recall from expository text, organization of information from expository text in notetaking, and expository writing. A nested analysis of covariance procedure was used for data analysis to account for teacher effects and group non-equivalence. The study was conducted over a six-week period in the spring semester. A model of direct instruction in analysis of expository text structure was developed by the researcher, using sample text passages similar to those encountered by seventh- and tenth-grade students in content area reading. Treatment group teachers were provided with lesson plans and materials and were given instruction in the model; comparison group classes were given no particular instructional treatment other than that normally conducted during this period.

This study investigated the relation of the Kaufman Assessment Battery for Children (K-ABC) with the Wechsler Intelligence Scale for Children - Revised (WISC-R) for learning disabled (LD) children, the relation of K-ABC Achievement subtests with other achievement tests, and the relation of verbal and perceptual abilities assessment and the K-ABC. One hundred white, middle to above socioeconomic status (SES), LD students 6 to 12 1/2 years old were administered the K-ABC in addition to the test battery used to identify them. Findings indicated significant differences (2<-01) between WISC-R Full Scale scores and KABC MPC scores, with MPC scores being 3.33 points lower. Significant correlations (2<-01) were found between the following: (a) WISC-R Performance scores and K-ABC Simultaneous scores, (b) K-ABC Sequential and Simultaneous scores, (c) WISC-R Performance and K-ABC Sequential scores, (d) K-ABC Arithmetic and WRAT Arithmetic, and (e) K-ABC Reading Understanding and the following: Woodcock Word Identification, Woodcock Passage Comprehension, WRAT Reading, and Durrell Silent Reading. The study found the MPC correlates higher with tests of perceptual ability than with tests of verbal ability. Results indicate the following: (a) the WISC-R and K-ABC can substitute each other when measuring overall intelligence, (b) the WISC-R and K-ABC do not measure …

The dual role of classroom teacher and athletic coach is commonly combined in public school systems, often resulting in job related conflicts. The purpose of this study was to examine the job attitudes of teacher-coaches as perceived by teacher-football coaches (n=283) and high school principals (n=43) and identify areas where role preference occurred. The teacher-coaches and principals responded to a job attitude instrument designed to measure attitudes concerning job related tension, participation in decision making, job involvement and job satisfaction during the roles of teaching and coaching.

The purpose of this study was to describe the extent and quality of prior knowledge, transactional nature, and social context of literacy knowledge demonstrated by young mildly handicapped learners. The study was based on current theories of literacy which view literacy growth as part of the total language system development, and ethnographic methods were used to gather and analyze qualitative data. Language and literacy events were observed in three special education classrooms including 43 students ranging in age from 4 years 1 month to 9 years 11 months. Major findings of the study included: (a) The children in this study demonstrated prior literacy knowledge much like that of non-handicapped peers, (b) Demonstrations of oral and written language system transactions decreased after students received formal instruction in reading and writing. And (c) children's ability to interpret print depended greatly on the presence or absence of context with the print.

Abuse in adult relationships as affected by stress, anxiety-proneness, and exposure to abuse as a child was examined using 579 North Texas State University undergraduates, Frequency and levels of abuse observed or received as a child and received or expressed as an adult were measured using a modification of Straus' Conflicts Tactics Scale (1979). Anxiety-proneness was determined by scores received on Spielberger's (1970) State-Trait Anxiety Inventory. Current levels of stress for the past two years were measured using the Life Experiences Survey (Sarason, 1978). Overall frequencies for received and expressed abuse (including physical and verbal abuse) in adult relationships were quite high (62.9 percent and 73.8 percent respectively). Females reported expressing significantly more abuse than did males. No gender differences were found for the receipt of abuse. Gender differences in types of violence were also examined. In addition, multiple regression was used to determine predictor variables for the expression and receipt of abuse. For males, receiving abuse as a child, positive stress scores, higher levels of anxiety-proneness, and observing father's abuse of mother significantly predicted expressing abuse as an adult. Observing mother's abuse of father and positive stress scores significantly predicted receiving abuse as an adult. For females, having received …

The problem of this study was to compare the effects of two methods of filmstrip presentation on student achievement. One method employed a personal robot to automatically advance a filmstrip projector in sequence with an audio cassette tape while the other method had a person manually advancing a filmstrip projector in sequence with an audio cassette tape. These were the findings of the study: The pretested experimental and control subjects learned from the sound/filmstrip. The pretested experimental and control groups' mean posttest scores were significantly higher (p < .05) than their pretest mean scores. The experimental groups did not achieve significantly higher mean scores (p > .05) on a posttest, delayed retest, or module mean tests than the control groups. Using the findings of this study, the following conclusions were drawn. Students Learn from a sound/filmstrip on robotic technology whether it is presented by a human being or by a robot. A robot is a viable alternative to the human teacher in situations where the student-teacher interaction is limited.

This study examined the effects of an Adlerian-based parent education program on parental stress and perception of Learning Disabled (LD) childrens' behavior. Forty parents, randomly assigned to treatment or waiting-list control groups, took the Parental Stress Index (PSI) and the Adlerian Parental Assessment of Child Behavior Rating Scale (APACBS) as pre and post tests. Parents in the treatment group attended a six-session Active Parenting program. No significant differences were found on the analysis of covariance for perceived parental stress following the parent education program. Seventy percent of the parents in this study had total PSI scores in the range defined as high stress by the PSI author. All of the PSI Child Domain pretest z scores were elevated indicating that parents perceive their LD children to be demanding, moody, distractible, and unadaptable. LD children's behavior is perceived as unacceptable and does not positively reinforce parents. The elevated z scores on the PSI parent Domain pretest indicate that parents of LD children feel less competent as parents and experience less attachment to their children than do parents of normal children. No significant differences were found on the APACBS following treatment, but 80 percent of the parents in the treatment group did …

This study was conducted to measure the effects of classroom instruction entitled Citizenship curriculum Training on high school discipline. Data for this study were collected and analyzed for fifty-eight ninth-grade students who had been referred to the principal's office three or more times the semester prior to the experimental treatment. An experimental group of twenty-nine students received citizenship curriculum instruction. The control group of twenty-nine students received only the school's traditional curriculum during second period class. Two teachers presented the citizenship curriculum training which included instructional units on beliefs, attitudes, emotions, anger, decision-making, communications, confrontation, positive attention, stress, peer pressure, authority figures, getting along in school, and the society game. Data were collected relative to grade-point average, absences, discipline referrals, and attitude toward high school as measured by the Remitters High School Attitude Scale. T-tests for correlated samples and analysis of covariance examined the effects of the Citizenship Curriculum Training on the four variables measured. The .05 level of significance was used to test the four hypotheses. The results of the study indicate that Citizenship Curriculum Training does not improve the students' gradepoint averages, absentee rate, lower the number of discipline referrals, and does not improve students' attitude as measured …

This study analyzed a random sample of thirty-six collective bargaining contracts between teachers and their respective boards of education in Wisconsin, New York, Tennessee, and California. The contracts were studied to assess the effect that collective bargaining has had upon the powers of principals over time. This was done by comparing each contract to a comprehensive list of traditional powers that were available to principals prior to collective bargaining (Pre-Collective Bargaining Power Profile of Principals). This analysis of contracts was a two-phase process. The first step was to identify whether or not the profile statements in the Pre-Collective Bargaining Power Profile were referred to in each contract. The second step was to describe how the presence of references to these statements affected the Power Profile of Principals. The principal's power was reported as being affected in three ways: deleted, constrained, or authorized. The general conclusion of this study was that the effect of teacher collective bargaining upon the powers of principals has been marginal. The data from the analysis of the contracts revealed that the majority (66 percent) of the statements in the Pre-Collective Bargaining Power Profile were not referred to in the collective bargaining contracts. The effects of the …

To investigate the effects of emotional arousal on information processing strategy, three different moods (sadness, anger, and happiness) were hypnotically induced at three different levels of intensity (high, medium, and low) in 29 male and female undergraduate students, while engaging them in a visual information processing task. Subjects were screened for hypnotic susceptibility and assigned to either a high susceptibility group or low susceptibility group to account for the attentional bias associated with this trait. All subjects were trained to access the three emotions at the three levels of intensity. During separate experimental sessions, subjects were hypnotized, and asked to access a mood and experience each level of intensity while being administered the Navon Design Discrimination Task, a measure of global and analytic visual information processing. Scores were derived for global processing, analytic processing, and a percentage of global to analytic processing for each level of mood and intensity. Two (hypnotic susceptibility) x 3 (emotion) x 3 (intensity level) repeated measures ANOVAs were computed on the global, analytic, and percentage scores. In addition, two separate ANCOVAs were computed on each dependent measure to account for the effects of handedness, and cognitive style. None of these analyses revealed significant main effects …

This descriptive study with quantitative aspects examined the phenomenon of elder abuse through the systematic review of 60 cases of elder abuse. Cases were randomly selected from the files of an Adult Protective Services agency in the North Central Texas area. Research questions examined the characteristics of the victims and abusers, types and duration of abuse, descriptions of abusive situations, the reporting and verification of abuse, case management strategies utilized by caseworkers, and the consequences of those strategies. The results of this study point to the probability of the elderly abuse victim being 75 years of age or older, female, white, and widowed. There did appear to be some connection between race and type of abuse with white victims more likely to experience physical and financial abuse. Approximately half of the elderly abuse victims had severe limitations in physical and/or mental functioning leading to some degree of dependence upon their abusers. However, eighty percent of the elderly victims resided in their own homes and half of these individuals were functionally independent. This study provided descriptions of the various types of abuse that were observed: physical, financial, emotional, passive neglect, and active neglect. Financial abuse was noted most frequently, and multiple …

The relationship among eosinophils, lysophospholipase activity and the immune response in animals infected with Trichinella spiralis was studied using in vivo and in vitro techniques. In an in vivo experiment, anti-thymocyte serum (ATS) was administered to mice infected with T. spiralis and its effects on intestinal lysophospholipase (EC 3.1.1.5.) activity, peripheral blood, bone marrow and intestinal eosinophilia were measured in the same experimental animal. The ATS caused a significant temporally related suppression of both the tissue lysophospholipase response and eosinophilia, in all three compartments. These findings support the hypothesis that parasite-induced eosinophilia is the cause of the increased lysophospholipase activity of parasitized tissue and that the responses are thymus cell-dependent. In vitro experiments demonstrated that the eosinophil was the primary inflammatory cell source of lysophospholipase among eosinophils, neutrophils macrophages and lymphocytes. The role of other cells and antigen in the production of the enzyme by the eosinophil was also investigated in vitro• Results demonstrated that eosinophils cultured with both T. spiralis antigen and other leukocytes yielded enzyme activities significantly greater than eosinophils cultured alone or with only antigen. More specific experiments showed that T-lymphocytes were the cells responsible for influencing the eosinophils' lysophospholipase activity in the presence of antigen, and …

This study evaluated the role of asymmetric processing of information in depression. Depression has been hypothesized to involve a deficit in the global processing of information (Tucker, 1982). This type of global processing has been manipulated through the use of hypnosis by Crawford and Allen (1983). In the current study, a 3 x 2 ANCOVA design allowed the comparison of three groups of subjects on their performance on a perceptual task measuring global perception. The task chosen was designed by Navon (1977) and consisted of designs which differed on global or local features. The groups were screened with the Beck Depression Inventory, the Harvard Group Scale of Hypnotic Susceptibility, and the Edinburgh Handedness Inventory, yielding 46 subjects divided into three groups of right-handed males and females. The experimental group consisted of high susceptible depressives from the community. The controls were one group of high susceptible normals and one of low susceptible depressives. All groups performed the Navon task under both waking and hypnosis conditions. Analysis of the results revealed a main effect for group (F(2, 86) = 9.60, p < .01) on the global scores. In addition, high social desirability scores predicted slower presentation times. However, hypnosis was not effective …

This lecture-recital deals with the two percussion sextets of Carlos Chavez. Each of the compositions is analyzed by examining compositional characteristics and performance problems. The selection, substitution, and construction of the necessary instruments for performance are explored. Suggestions for stage set-up are also included. The percussion ensemble has become an integral part of most high school and university percussion programs. Much of the literature composed for this medium has not become part of the standard literature. Chlvez's Toccata has obtained its place in the literature—it is one of the most often performed percussion works in the world. Although Tambuco has not yet attained the same status as Toccata, it is, nevertheless, an important contribution to the literature. An attempt is also made to identify the significance of these works by examining some of the early influences on Chavez's compositional style both from his native Mexico, and from other composers writing for percussion ensembles.
