(4+2)-Cycloaddition Reactions of Ketenes; Pyranones

Description: This study deals with the (4+2)-cycloaddition reactions of 4-π electron compounds with ketenes. Chloroketenes were generated in situ from the corresponding chlorinated acid chlorides in the presence of the ketenophiles. Chloro-, dichloro- and diphenylketenes reacted with 1-methoxy-3-trimethylsiloxy-l,3-butadiene, and 2,4-bis(trimethylsiloxy)-1,3-pentadiene to yield the corresponding dihydropyrans. The dihydropyrans yielded substituted 4-pyranones on hydrolysis.

Ability Grouping in College Beginning Media Writing Classes

Description: The problem with which this investigation is concerned is that students of unequal writing ability are frequently placed in the same beginning media writing classes in college journalism. It is difficult for a teacher to be effective when the ability of the students ranges from those who cannot write clear complete sentences to others whose work already appears in newspapers and magazines. The purpose of this study is to determine whether students who are ability grouped into slow—average and advanced groups do the same, better, or worse than heterogeneously grouped students. In the spring semester of 1987, students in Journalism 1345, Media Writing laboratory, at the University of Texas at Arlington, were given a pretest to determine how well they wrote a simple news story and a simple feature story. On the basis of that test, which was graded by three raters, the students were placed in two separate ability groups in three classes. The fourth class contained students with heterogeneous abilities who were not placed in groups. At the end of the semester a posttest was given in news and feature writing. A two-way analysis of variance was used to analyze the posttest scores of sixty-seven students. There was no significant difference in the posttest scores of students who were grouped homogeneously and those who were grouped heterogeneously. The difference in the scores of heterogeneously grouped advanced students and homogeneously grouped advanced students was not significantly different from the difference between the posttest scores of heterogeneously grouped slow-average students and homogeneously grouped slow-average students.

Absorption, Relaxation, and Imagery Instruction Effects on Thermal Imagery Experience and Finger Temperature

Description: A skill instruction technique based on cognitive behavioral principles was applied to thermal imagery to determine if it could enhance either subjective or physiological responsiveness. The effects of imagery instruction were compared with the effects of muscle relaxation on imagery vividness, thermal imagery involvement, and the finger temperature response. The subjects were 39 male and 29 female volunteers from a minimum security federal prison. The personality characteristic of absorption was used as a classification variable to control for individual differences. It was hypothesized that high absorption individuals would reveal higher levels of imagery vividness, involvement, and finger temperature change; that imagery skill instruction and muscle relaxation would be more effective than a control condition; and that the low absorption group would derive the greatest benefit from the imagery task instruction condition. None of the hypotheses was supported. Finger temperature increased over time during the experimental procedure but remained stable during thermal imagery. The results suggest that nonspecific relaxation effects may best account for finger temperature increases during thermal imagery. Results were discussed in relation to cognitive-behavioral theory and the characteristic of absorption.

The Academia Musical of Pablo Minguet y Yrol: A Translation and Commentary

Description: Pablo Minguet y Yrol's Academia Musical of 1752, M891 in the Bíblioteca Nacional of Madrid, is a loosely organized collection of tutors for thirteen musical instruments: guitar, tiple, mandola, cittern, bandurria, psaltery, clavichord [i.e., keyboard], organ, harp, violin, transverse flute, recorder, and flageolet. The tutors concerning the guitar and related instruments are by far the most comprehensive; topics covered include basic playing technique, figured-bass accompaniment, and notation, both mensural and tablature. Most musical examples are given in both types of notation. The thesis is a complete translation of the Academia Musical, including the texts of the illustrations, with an introductory commentary giving the historical background of music education in eighteenth-century Spain, a brief review of European musical-instrument tutors in general, and an analysis of Minguet's tutors in particular.

Academic Achievement and the Ability of Post-Secondary Students to Read Assigned Materials

Description: This study provides a rationale for adopting course materials. It demonstrates the relationship between ability to read assigned materials and academic achievement, and that selection of materials creates two groups having different probabilities of success. The sample was selected from a population of all students enrolled in Principles of Economics courses at North Texas State University in the spring semester of 1986. The Nelson-Denny Reading Test was used to determine reading ability. Assigned materials were analyzed for readability. A frustration level was determined and used to divide the sample: the group of interest, those with reading abilities below the frustration level who underwent the treatment of reading materials written above their ability to comprehend; and the comparison group, those with reading abilities above the frustration level who did not undergo the treatment.

Acculturation and Locus Of Control: Their Relationship to the Use of Inhalants

Description: This study analyzed the effects of acculturation, locus of control, and incidence of inhalant use on Mexican Americans. Information was collected from 275 subjects at three middle schools and one treatment center. The instrument consisted of Levenson's Locus of Control Scale, the Acculturation Rating Scale for Mexican Americans, and an incidence of use and family relationship questionnaire developed for this study. Statistical analysis indicated a relationship between acculturation and inhalant use. Further examination revealed relationships between a family members' use and subjects' inhalant use; subjects' alcohol use and inhalant use; and subjects' marijuana use and inhalant use. Information implied that prevention and intervention programs should focus on children of substance users and further research is needed surrounding the role of acculturation.

Accuracy of Eyewitness Memory Under Leading Questioning: The Effects of Hypnosis and Anxiety

Description: Hypnosis has gained substantial support in the psychological community, as well as related health professions. The intense renewal of interest in hypnosis has also affected our legal-judicial system. Many police investigators trained in hypnosis operate from an exactcopy memory theory. They claim eyewitness eyewitness retrieve veridically stored memory traces from long-term memory, if questioned under hypnosis. Conversely, other researchers ascribe to a reconstructive memory theory. They believe hypnosis increases the likelihood of eliciting erroneous memories from eyewitnesses, especially under leading questioning. The purpose of the present investigation was to test the effects of hypnotic induction and anxiety on the accuracy of subjects' memory for eyewitnessed events when questioned with leading, non-leading, and embedded misinformation questions.

Accurate Empathy and Rorschach Interpretation

Description: Although the Rorschach is one of the most widely used psychological assessment techniques, its empirical support has been equivocal. One possible explanation for this lack of empirical support is the tendency for researchers to study only the assessment tool with little regard for the clinician using it. The current study examined one clinician variable (empathy) and its relationship to accuracy of interpretation of the Rorschach. The literature regarding Rorschach theory and research and empathy theory and research was reviewed in an attempt to clarify the similarities between empathy as an important factor in psychotherapy and its importance in the assessment process. The present study measured empathy by using the Davis Empathy Questionnaire and a Taped Excerpt Response Measure.

The Achievement of Student Development Tasks by Male College Scholarship Athletes and Non-Athletes: A Comparison

Description: The problem with which this study is concerned is to determine whether or not differences exist in the achievement of student development tasks by college student athletes and non-athletes. The investigation also tested for differences in the achievement of developmental tasks between athletes and non-athletes based on the variables of race (black or white), classification, and interpersonal behavior orientation. The sample was composed of 276 male students (201 non-athletes and 75 athletes) who attend a large private university in Texas. Each participant completed both a student developmental task inventory questionnaire, which measures individual achievement of the tasks of developing autonomy, purpose, and mature interpersonal relationships, and an interpersonal relationship orientation-behavior instrument, which measures an individual's orientation to others on the scales of inclusion, control, and affection.

Act I, Scene 2 of Hamlet: a Comparison of Laurence Olivier's and Tony Richardson's Films with Shakespeare's Play

Description: In act I, scene 2 of Shakespeare's Hamlet, one of the key themes presented is the theme of order versus disorder. Gertrude's hasty marriage to Claudius and their lack of grief over the recent death of King Hamlet violate Hamlet's sense of order and are the cause of Hamlet's anger and despair in 1.2. Rather than contrast Hamlet with his uncle and mother, Olivier constructs an Oedipal relationship between Hamlet and Gertrude--unsupported by the text--that undermine's the characterization of Hamlet as a man of order. In contrast, Tony Richardson presents Claudius' and Gertrude's actions as a violation of the order in which Hamlet believes.

The Acute Effects of Intermittent Running on Serum CK and LDH Enzyme Activities in Runners and Non-Runners

Description: Acute effects of repeated sprinting upon serum creatine kinase (CK), lactic dehydrogenase (LDH), and isozymal activities were studied in five collegiate runners (R_s) and six non-runners (NR_s ). After an intermittent running treadmill test, blood sampling showed three-fold mean increases in CK with no change in LDH in both groups; group differences were insignificant (p>.05). Results suggest (1) intense anaerobic exercise produces moderate enzyme elevations; (2) relatively equivalent exercise intensities are critical to enzyme responses in exercising individuals of varying fitness levels; and (3) exercise-induced enzyme release may be consequential to muscle cell membrane permeability changes from decreased intracellular high-energy phosphates.

The Adenosine Antagonist Aminophylline Attenuates Pacing-Induced Coronary Functional Hyperemia

Description: Left coronary blood flow (LCBF), left ventricular oxygen, extraction [(a-v)O₂ ], and myocardial oxygen consumption (MVO₂) were monitored in 10 dogs. HR was paced at 120 bpm and then increased to 180 bpm to elicit a hyperemic response (ΔLCBF). During the hyperemia, the vaso-dilatory response to exogenous adenosine (F_AD) was tested. Twenty min. after injection of aminophylline (100 mg/i.v.), HR was again increased. F_AD was again tested. The pacing-induced increase in MVO₂ (ΔMVO₂) was not affected by aminophylline (P>0.05). However, the slope ΔLCBF/ΔMVO₂ was decreased, and the slope (a-v)O₂ /ΔMVO₂ was increased. F_AD was also decreased and the magnitude of the reduction was correlated with the decrease in ΔLCBF/ΔMVO₂ (r=0.82). These results suggest that adenosine may play an role in coronary functional hyperemia induced by increases in heart rate.

Adenylate Energy Charge Determinations of Soil Bacteria Grown in Soil Extract Medium

Description: The adenylate energy charge values of twenty bacteria isolated from soil and cultured in a medium consisting of soil and distilled water were determined by the luciferin-luciferase bioluminescense method. The purpose of this study was to examine the growth and energy charge values of these organisms in soil extract medium, and to determine what effect the addition of glucose has on their energy charge values. Three of the organisms employed in this study showed energy charge values similar to those reported for bacteria grown in enriched media. The remainder of the isolates demonstrated low energy charge values, and scant growth in the soil medium.

Adherence/Compliance to Exercise Prescription: A Test of the Self-Efficacy Model

Description: It has been well-documented in the literature that there are many physical and psychological benefits to be derived from regular aerobic exercise. It has also been noted that adherence/compliance to aerobic exercise regimens tends to be quite low. Investigators have found that a number of factors tend to correlate with adherence, but it has been difficult thus far to determine a mechanism which underlies a tendency to adhere versus a tendency to drop-out. This study examined the problem of non-adherence from the perspective of Self-Efficacy Theory (Bandura, 1977). Subjects for this investigation included all patients seen during a four week period in the Cooper Clinic at the Aerobics Center in Dallas, Texas. Patients at the clinic receive a complete physical examination and health prescriptions based upon the results of their examination. During this four week period, half were administered a Self-Efficacy Questionnaire. Approximately three months later all patients seen during this four week period received a followup (adherence questionnaire in the mail). It was hypothesized that there would be a positive relationship between responses on the Self-Efficacy Questionnaire and responses on the Adherence Questionnaire. A second hypothesis stated that there would be a positive relationship between items which specifically pertained to exercise on each of the questionnaires. In addition, it was expected that there would be no difference in adherence rates between those who made self-efficacy judgments and those who did not. Results of a t-test conducted between the group which made self-efficacy judgments and the group that was not asked to make such an evaluation demonstrated no significant difference in adherence rates. A correlational analysis revealed that there was not a statistically significant relationship between total self-efficacy scores and total adherence scores. There was, however, a statistically significant relationship between levels of exercise self-efficacy and levels of exercise adherence. ...

Admission Factors Related to Success in Doctoral Programs in Vocational-Technical Education in Texas and Oklahoma

Description: This study identified the admissions criteria for selected doctoral programs in vocational-technical education in Oklahoma and Texas and investigated the relationship of these criteria to success in the doctoral programs. Success in the doctoral programs was identified in terms of cumulative doctoral grade point average. Data were obtained through a questionnaire designed to ©licit both general information concerning admissions criteria for vocational-technical doctoral programs at the selected institutions and to collect specific information on a random sample of twenty doctoral candidates from each of the four selected institutions. Factors considered included birthdates, gender, scores on admissions tests, grade point average in the masters program, the year the latest masters was completed, number of colleges attended, and cumulative doctoral grade point average. A statistical analysis using nine separate one-way analyses of variance determined that four of the nine factors considered proved to be statistically significant at the .05 level or better when correlated with the criterion variable (cumulative doctoral grade point average). Those factors were gender, Graduate Record Examination verbal and composite scores, and masters grade point average. The results of the study basically parallel findings of research concerning admissions criteria and success in graduate programs in other areas. Additional research efforts should address the issue of determining the most appropriate decision logic model for making admissions decisions in programs at the graduate levels.
