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 study examined the relationship among the factors of parental stress, marital adjustment, life event stress, and behavior problems of children and whether the sources and levels of parental stress, marital adjustment, and life event stress differed among families of children with . behavior problems and families whose children did not experience behavior problems. The subjects for this study were 60 mothers and their children from the North Texas metropolitan area chosen from two populations. Group I was composed of mothers of 30 children referred to a university related counseling center for behavior problems. Group II was composed of 30 mothers of children identified as not experiencing difficulty. Each mother completed the Parenting Stress Index (PSI), Short Marital Adjustment Test (SMAT), and Social Readjustment Rating Questionnaire (SRRQ). Hotellings T tests were used to determine whether the groups differed on sources and levels of parenting stress, marital adjustment, and life event stress. The groups differed significantly on the variables of sources and levels of parenting stress but not on marital adjustment or life event stress. The multiple regression technique was used to determine which variable or combination of variables would predict group membership. Parenting stress was found to be the best …

The problem of the study was the inadequate education of handicapped students in Nigeria. The primary purpose of the study was to develop a construct based on the United States models and research on special education, and to compare educational provisions for Nigerian students with the available educational opportunity for handicapped students. In order to achieve the stated objectives of the study, two methodological approaches were utilized: (1) Likert scale for opinion questionnaires, and (2) personal interviews. Both of these instruments included demographic information about the participants. The questionnaire was categorized into three areas (differences between educational opportunities for non-handicapped and handicapped students, formal learning opportunities for handicapped Nigerian students, and factors for being attentive or not being attentive to special education). The interview instrument focused on special education constraints, responsibility for special education provision, and improvement in education for the handicapped. Based on the findings of the study, the following conclusions were reached. 1. Handicapped Nigerian students do not have equal educational opportunities, as compared to non-handicapped students. Therefore, equal instructional opportunities should be provided for handicapped and non-handicapped students. 2. The federal and state governments of Nigeria should be financially responsible for special education. Therefore, the administration of …

This study examines nursing students' adoption of inferential sets in a clinical situation. The investigation determines (1) the particular inferential set(s) nursing students adopt toward a patient in a clinical situation; (2) the particular inferential set(s) adopted by sophomore and senior nursing students in a clinical situation; and (3) whether or not inferential sets adopted by the sophomore and senior nursing students differ. Sophomore and senior nursing students at a woman's university in Texas were asked to complete a research tool designed to determine inferential set adoption.

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.

This study analyzes the status and job functions of the 546 elementary school assistant principals in Texas during the 1985-1986 school year. It is concerned with the status of the position and the degree of responsibility assigned to the assistant principal for forty-eight specific job functions in the actual and ideal practice. A sample of 125 assistant principals, 125 supervising principals and a population of 135 superintendents whose districts employ assistant principals were included in the study. All three groups completed the role survey instrument. The results were analyzed by using the one-sample chi-square test to determine whether significant differences existed among the perceptions of the superintendents, principals, and assistant principals at the .01 level. The return rate was 60.8 percent for the assistant principals and principals and 84.6 percent for the superintendents.

The problem investigated by this study was that of understanding types of behaviors exhibited by participants in negotiations processes and impact of behaviors on collective bargaining in Nigeria. The study's three purposes were to describe the nature and extent of interpersonal conflict that occurs in collective bargaining, to determine the consequences that stem from such conflict, and to suggest the behaviors and performances during the face-to-face negotiations that should exist to enhance labor-management relations in Nigerian public education. This study examined behavior in negotiations by using simulation, i.e., a quasiexperimental method. Four outcomes of negotiations--time required to reach agreement, terms of agreements, verbal behavior exhibited during negotiations, and satisfaction derived by negotiators in negotiations—were examined.

The purpose of this study is to test the utility of Talcott Parsons' AGIL Model, i.e., Adaptation, Goal Attainment, Integration, and Latency (Pattern Maintenance) in evaluating the program effectiveness of a community mental health center (CMHC). The model provided a conceptual framework for the selection of appropriate variables. The dependent variable in this study is the overall evaluation of the CMHC as measured through the perception of community leaders. Fourteen hypotheses were constructed to identify and test the relationship among the AGIL criteria and the use of a selected set of independent variables. Data for this study were collected from primary and secondary sources. Secondary data were obtained from the Texas Department of Mental Health and Mental Retardation in Austin and the CMHC center in Eton. Primary data were collected through personal interviews of general community leaders and influential persons in health-related activities in the community. The selected independent variables included the scope of leadership, the attitude towards this community, socio-economic status, knowledge of the CMHC, and the commitment and involvement in the CMHC. Data indicated that Parsons' criteria for evaluating the CMHC's program were comprehensive and related to each other both positively and negatively. Among the selected independent variables, …

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 …

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 …

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 …

While musical sources and documents from throughout the Middle Ages reveal that mode was an enduring and consciously derived trait of monophonic chant, modality in later polyphony shares neither the historical span nor the theoretical clarity of its monophonic counterpart. Modern theorists are left with little more than circumstantial evidence of the early development of modality in polyphony. This study attempts to shed light on the problem by detailed analysis of a select body of paraphrase masses from the early sixteenth century. First, it correlates the correspondence between the paraphrased voice and the original chant, establishing points of observation that become the basis of melodic analysis. Then, these points are correlated with known rules of counterpoint. Exceptions are identified and examined for their potential to place emphasis on individual mode-defining pitches. A set of tools is derived for quantifying the relative strength of cadential actions. Levels of cadence are defined, ranging from full, structural cadences to surfacelevel accentuations of individual pitches by sixth-to-octave dyadic motions. These cadence levels are traced through the Missae de beata virqine repertoire from c. 1500-1520, a repertoire that includes masses of Josquin, Brumel, La Rue, Isaac, and Rener. While the Credos, based on two chant …

The effects of a computer program (Health Imagery Technology Systems, HITS) designed to promote attitude and cognitive changes through elicitation of evoked response potentials were evaluated with chronic pain patients. A treatment and control group were used for comparison (52 patients, 22 females, 32 males, mean ages 47). Wechsler Adult Intelligence Scale-Revised subtests, a Semantic Differential scale, the Health Attribution Test, an imagery protocol, the McCoy-Lawlis Pain Drawing, and the Zung Depression scale were used at admission and discharge to measure change. A pre- post-mood thermometer was used with the treatment group. The hypotheses that the treatment group would show significant changes on these measures were tested with a two group repeated measures analysis of variance design. No significant changes were noted for either group on the intellectual measures, on health attitudes, or reports of pain. The similarities subscale showed significant within group variance (F = 5.46, p < .023). One bipolar adjective pair indicated significant differences (F = 4.79, p < .035), possibly a result of chance. One of seven imagery measures suggested a significant improvement in strength of imagery for the treatment group (F = 18.2, p < .00008). Both groups showed significantly improved imagery of body defenses …

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 …

This study addresses how the temperament characteristics of seven year old learning disabled students are viewed in relation to those of the normally achieving students. Teacher perceptions, parent perceptions, and teacher versus parent perceptions are examined utilizing the six dimensions (activity, adaptability, approach/withdrawal, intensity, distractibility, and persistence) and the three factors (emotionality, sociability, and persistence) of the Temperament Assessment Battery.

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 …

This study described the way teachers used questions with skilled and less skilled readers during reading instruction. The cognitive level and functions of questions were analyzed based on data collected through direct observation within the natural environment of the classroom. In addition, the patterns of questioning which included wait-time and sequencing of questions were identified and reported. Twenty sixth grade teachers randomly selected from a metropolitan school district were observed while instructing skilled readers and less skilled readers. Data collected during non-participatory observation of reading instruction through audiotape recordings, a low-inference observation instrument, and field notes were analyzed using the chisquare statistic, log-linear analysis, and descriptive statistics. Each question/response/response loop which occurred during the eighty observations was analyzed as to the cognitive level and function of the question, designation and wait-time of the student's response, the appropriateness, type, and length of the student's response, and the content of the teacher's response. Within the limitations of this study, the following conclusions have been formulated. 1. Teachers use different cognitive levels of questions for particular functions as dictated by the specific needs and characteristics of the students in the skill level. 2. Although teachers ask the majority of questions at the cognitive-memory …

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.

This investigation traces the history and development of music theory in Mexico from the date of the first Mexican treatise available (1776) to the early second half of the nineteenth century (1866). This period of ninety years represents an era of special importance in the development of music theory in Mexico. It was during this time that the old modal system was finally abandoned in favor of the new tonal system and that Mexican authors began to pen music treatises which could be favorably compared with the imported European treatises which were the only authoritative source of instruction for serious musicians in Mexico.

The purpose of the study was to determine the effects that achievement and locus of control have on a person's ability to estimate the passage of time. The subjects were a group of 116 college students enrolled in an introductory psychology course at Mountain View College. Achievement was measured by the grade obtained in the course, and the locus of control was measured by the individual's score obtained on the Rotter Internal-External Locus of Control Scale. Five different cutoffs were used to determine the locus of control orientation (internal/external). The data were analyzed using analysis of variance techniques. No significant differences between any of the groups were found.

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 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.

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 …

High performance liquid chromatography was used to measure ribonucleoside triphosphates in microbial samples. Anion exchange columns in a radial compression module were used to separate and quantify purine and pyrimidine ribonucleotides. Endogenous ribonucleoside triphosphates were extracted from Escherichia coli and pseudomonas aeruginosa using three different solvents, namely trifluorocetic acid (TFA; 0.5M), trichloroacetic acid (TCA; 6 per cent w/v) and formic acid (1.0M) Extracts were assayed for uridine 5'-triphosphate (ATP), and guanosine 5'-triphosphate (GTP) by using anion exchange radial compression high performance (pressure) liquid chromatography. The three extraction produres were compared for yield of triphosphates. E. coli, the TFA extraction procedure was more sensitive and reliable than TCA and formic acid extraction procedures, but , in P. aeruginosa, the best yields of ATP and GTP were obrained following extraction with TFA. Yields of UTP and CTP increased when extraction was performed in TCA. These data illustrate that different extraction produres produce different measures for different triphosphates, a point often overlooked.
