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

The Adenosine Antagonist Aminophylline Attenuates Pacing-Induced Coronary Functional Hyperemia
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.

Allocation of Attention: Effects on Classical Conditioning
According to Deikman (1966), meditation (defined as a training to sustain attention) has a deautomatizing effect. This ascertion was utilized in the present study as a departure point and explored within an information processing framework for classical conditioning. A sample of 48 college students was selected and randomly assigned to four conditions with different instructional sets involving allocation of attention during a classical conditioning background situation. The basic hypothesis of the study was that provided arousal factors were controlled, focusing of attention upon internal stimulation (i.e. breathing) could delay or attenuate the affect of conditioning, habituation and extinction as compared with instructions to externally allocate attention (on the CS and US). A secondary hypothesis predicted that for subjects under switching conditions changing from internal to external allocation and vice versa would produce a more pronounced extinction pattern as compared with subjects under non—switching conditions.

Analysis of Behavioral Perceptions and Values Among Staff and User Groups of the Junior High Schools within an Independent School District
This research was designed to determine if significant differences exist among the behavioral perceptions and values held by staff and user groups of all junior high schools in a selected independent school district. This study also evaluates the applicability of social profiles to describe perceived organizational behavioral characteristics. Two published, validated survey instruments were used to collect the data. The questionnaires were distributed to randomly selected teachers (staff group) and parents and Parent-Teacher Association officers (user group) from each of the five junior high schools. Of 206 sets of questionnaires distributed, 166 (80.5 percent were returned. Computer analyses of these raw data provided both individual perceptions and descriptions for each junior high school in addition to individual values for each school's staff and user group. The data results show that the social profiles of two of the five schools are perceived differently by both their staff and user groups; furthermore, there are significant differences between the values held by the staff and user groups for each of these schools. For the other three schools, there are minor differences of perception by staff and user groups of their schools' social profiles and also among the values held by the staff and …

An Analysis of Current Faculty Evaluation Practices in Two Selected Universities in Thailand
The purpose of this study is to analyze and compare the current faculty evaluation practices in two universities in Thailand as perceived by faculty and administrators. Although both institutions are universities, one is notably larger and more diversified. From a sample population of 450 (250 each), the response rate was 71.8 per cent. A survey instrument was used to collect the data early in 1984. Statistical procedures used in the analyses of data include frequency and percentage of responses, analysis of variance for split-plot repeated measures design, t tests, and binomial distribution as required to answer the twelve research questions designed to guide the study.

An Analysis of the Reliabiltiy of Management Estimates of Expected Future Net Revenues from the Production of Proved Oil and Gas Reserves
The research undertaken in this study is designed to examine the reliability of management estimates of expected future net revenues from the production of proved oil and gas reserves determined in accordance with the requirements of the prediction model specified in ASR No. 253. The issue of the required disclosure of earnings forecasts has been a topic of considerable controversy for many years. Within that controversy, the most frequently encountered opposition questions the reliability and ultimate utility of earnings forecasts. Similar opposition to both past and present forecast disclosure requirements exists in the oil and gas industry. In order to examine the reliability of management estimates of expected future net revenues, a two-part analysis was conducted. In the first part of the analysis, error metrics comparing management forecasts to actual results were computed and examined. Included in the examination were various relationships among and within the computed metrics. In the second part of the analysis an attempt was made to establish the association between the error metrics and specific related variables. It was anticipated that the degree of association determined would provide evidence of the relative accuracy of management in predicting the timing and volume of future production within the …

Androgyny and Sex-Role Measurement: A Personal Construct Approach
Recent research into sex roles has been heavily influenced by androgyny theory, and by the development of the Bern Sex-Role Inventory (BSRI; Bern, 1974). Psychological androgyny is the combination, in one individual, of both culturally defined masculine and feminine personality traits. The Sex-Rep, a new instrument for assessing sex role which is aimed at rectifying certain problems associated with the BSRI, was then described. The Sex-Rep, the BSRI (Bern, 19 34), the Texas Social Behavior Inventory (TSBI; Spence & Stapp, 1974), the Beck Depression Inventory (BDI, Beck, 1967), and a self-concept thermometer, were given to 100 male and 108 female undergraduates. Results indicated that the BSRI and the Sex-Rep are both valid sex-role instruments, insofar as they both discriminate between males and females. They tend to measure nonredundant components of sex role as indicated by a lack of overlap between their sex-role classifications. The present study did not find any support for the balance model of androgyny which suggests that high masculinity and high femininity interact by balancing each other to produce a healthier, more behaviorally flexible individual. BSRI masculinity (M) was strongly related to adjustment in both sexes, but BSRI femininity (F) had little impact. This relationship between BSRI …

Announcement Effects of Bond Rating Changes on Common Stock Prices
This dissertation examines the reaction of common stock prices to changes in bond ratings by Moody's Bond Service. The question is whether an announcement of a re-rating by Moody's is new information. There are only two studies of stock price reaction to bond changes and the results are conflicting. Pinches and Singleton (1978) [PS] concluded that any reaction comes well before the re-rating. Griffin and Sanvicente (1982) [GS] found that their portfolio test indicated that rating changes do convey new information. This was particularly true for downgradings. Both studies used monthly data and neither performed a statistical testing of residual reversals. PS provided a graph of the residuals which indicated the presence of a reversal trend. GS provided no information on this topic. This study, using daily data and the cumulative prediction error technique, finds that bond re-ratings offer new information. The results indicate that the market only partially anticipates the bond change. For the downgrades, the excess return on the announcement day is .6% which is statistically significant. The residuals reverse after the announcement day, but are not statistically significant. The upgrades do not have a significant reaction on the announcement day, but have a statistically significant negative reaction …

Broadcast Advertising Sales Education: A Comparison of Perspectives of Broadcast Managers and Broadcast Educators in the South-Central Region of the United States
The purpose of this study is to identify and compare the skills and knowledge areas that are valuable for success in broadcast advertising sales from the perspectives of broadcast managers and broadcast educators and to identify and compare to what degree recent graduates of broadcast-communication, business, and other majors perform or exhibit these skills and knowledge areas as perceived by selected broadcast managers and broadcast educators. The opinions of the broadcast managers and broadcast educators were determined from responses to a questionnaire of fifty-six items. The questionnaires were distributed to the chairs of the departments or areas responsible for broadcast curricula at forty-two four-year universities as listed by the 1983 Broadcasting-Cablecasting Yearbook [Sol Taishoff, editor, Washington, Broadcasting Magazine] as offering degrees in broadcasting, and 126 broadcast managers who were randomly selected from the broadcast markets in which the forty-two educational institutions are located.

Calcium Aluminates Synthesis, Characterization, and Hydration Behavior
The hydration behavior of the calcium aluminates as a function of the glass content, the curing temperature, and the water-solid ratio was investigated. In order to keep them from influencing the results, the free-lime content and the surface area of all samples were kept constant, whenever possible. Samples were hydrated with a water-solid ratio of 10/1 for periods of 1 to 90 days. Three curing temperatures were studied; 2°C, 25°C, and 50°C. Samples were hydrated in tightly sealed polyethylene containers to prevent reactions with atmospheric carbon dioxide. The hydration was followed by X-ray diffraction and thermal analysis. Only two samples, Hexacalcium Tetra-alumino Magnesium Silicate and Tricalcium Magnesium Dialuminate, were successfully prepared in an amorphous form. These compounds were used to investigate the effect of glass content on the hydration behavior. Results indicate that when the glass content is increased a corresponding increase is found in the percent combined water. Samples hydrated at 25°C were influenced by changes in the glass content to a greater degree than were those hydrated at either 2°C or 50°C. The effect of the water-solid ratio on the hydration behavior of the calcium aluminates was studied using the compounds; Hexacalcium Tetra-Alumino Magnesium Silicate/ and Dodecacalcium Hepta-Aluminate. …

A Case Study of the Public Relations Programs of the Six Southern Baptist Seminaries
The study examined the similarities and differences in the public relations programs of the six Southern Baptist Convention-owned seminaries. Using data collected from surveys and interviews, the study found the general perception of public relations at each seminary good, although some constituencies did not understand the public relations program's purpose. Cooperation among the six seminaries was limited, and most respondents said individual needs kept the seminaries from working more cooperatively. The diversity of primary job responsibilities makes cooperation limited since all programs do not share the same assignments. Limited historical documentation is available on the growth of the public relations programs. The study includes four chapters: a general introduction; an historical overview; analysis of data; and conclusions and recommendation for further study.

A Comparative Study of Opinions Concerning Faculty Teaching Behaviors Among Faculty Members and Senior Teacher Training Students in Six Teachers Colleges in Bangkok Thailand
The purpose of this study is to compare the opinions concerning faculty teaching behaviors among groups of faculty members and senior teacher training students in six teachers colleges in Bangkok, Thailand. Five research hypotheses guided the data analysis for this study; the variables used were sex, age, teaching experience, and college of employment. A published, validated survey instrument, which lists sixty-one behavioral items and incorporates a Likert-type response scale, was used to collect the data. Random sampling of the population corresponded to existing male-female ratios for each group at each schools, with the exception of one school that has only female students. From the sample of 480, the total response was 85.6 percent. In order to test for significant differences of opinion among the variables and between the groups at the .05 level, t and F tests were applied. The data indicate that 70.5 percent of the 190 responding faculty are females who have taught for more than ten years; females also constitute 72.4 percent of the 221 senior teacher training students. In regard to opinions of appropriate faculty teaching behaviors, significant differences were found between faculty and students (faculty members had higher mean scores) and between male and female …

A Comparative Study of the Effectiveness of the Relaxation Response and Personalized Relaxation Tapes in Medical Technology Students
This investigation was a development of a Personalized Relaxation Technique which was used in a comparative study of the effectiveness of this technique with the Relaxation Response, a popular relaxation method. The purpose of the study were (1) to design a Personalized Relaxation Technique and (2) to determine if this Personalized Relaxation Technique is as effective as the Relaxation Response. From the analysis of the data, no significant difference was found tin the three groups. Therefore, the two hypotheses were rejected. The conclusion of the study were (1) discrepancies exist in the literature concerning various relaxation techniques, (2) individual differences may be responsible for these discrepancies, and (3) fine tuning is needed between the theoretical concepts of a study on a relaxation technique and the research measures used to explore these concepts.

A Comparison of Counterconditioning and Role-Playing Strategies in the Hypnotic Treatment for Cigarette Smoking
This study compared the relative efficacy of two different theoretically-derived strategies in the hypnotic treatment for cigarette smoking. The use of counterconditioning suggestions (present or absent) was compared to the use of role-playing suggestions (present or absent) in a two-way factorial design. Also investigated was whether there were any pretreatment variables which could predict successful long-term smoking control. Fifty adult chronic smokers were matched on the dimensions of baseline smoking rate, number of years smoking and number of previous attempts to quit smoking, then assigned to one of four treatment groups. All subjects were offered four sixty-minute group hypnotherapy treatment sessions over a three week period, with smoking rate assessed at the second, third and fourth sessions, and at one-month, three-months and six-months post-treatment. The two dependent measures of percentage reduction from baseline smoking rate and percentage of subjects in each treatment group remaining abstinent from smoking showed similar results. ANOVA procedures found a significant Time of assessment X Counterconditioning interaction, indicating that the use of counterconditioning suggestions facilitates the long-term maintanence of smoking control more than the use of role-playing suggestions or a "hypnotic relaxation" treatment using no specific suggestions. The demographic variables of increased age, having a smoking-related …

A Comparison of the Acoustical Properties in Solo and Ensemble Performance of the Trombone
The specific problems investigated involved identifying and describing the characteristics of fundamental frequency, overall intensity, and spectral content in unaccompanied and ensemble performance settings. Additionally, comparisons and descriptions of the relationships among these acoustical parameters were made. Fifteen trombonists were used as research subjects. Each subject recorded a selected musical excerpt in the following performance modes: high register unaccompanied, harmonic, and unison ensemble; and low register unaccompanied and unison ensemble. Tape recordings of these subjects were used in conjunction with certain electronic apparatus to obtain data on frequency, intensity, and spectral content. Based on these data, descriptions of these acoustical parameters and comparisons of unaccompanied and ensemble performance settings were made.

The Composing Processes of Blind Writers
An examination of the composing processes of blind writers was conducted to determine the strategies used by these composers. Two individuals blind from birth and two persons blinded later in life participated in the study. Using participant observation and stimulated recall, the researcher examined the composing processes of these subjects. Each individual participated in four writing sessions and used the compose-aloud technique where by the composer repeats orally any thoughts that occur during writing. In addition, an interview was conducted with each participant which provided a writing history, attitude toward writing, and composing strategies. Results of the research indicated that blind writers use the same basic processes of writing as reported for sighted writers. Blind writers in this study did not make written plans prior to writing and spent between one and four minutes in prewriting. Planning was an ongoing feature of the composing process. The writers in this study demonstrated the recursive feature of composing. Rescanning was a continual part of their composing sessions . Three of the subjects reported using rescanning for planning and editing. One individual reported using rescanning for editing only. Some differences were found in the blind writers as compared to the research on sighted …

The Control of Surface Skin Temperature Through Hypnosis and Hypnotic Age Regression
A total of 60 male and female subjects scoring between 0-5 and 8-12 on the Harvard Group Scale of Hypnotic Susceptibility: Form A underwent hypnosis procedures, hypnosis and age regression procedures to age 10, or were read an article about hypnosis. All subjects then listened to 20 minutes of directed imagery for warming and cooling the hands. Skin temperature was monitored on both index fingers. Dependent measures were the difference between each subject's highest temperature and baseline temperature, the difference between each subject's baseline temperature and lowest temperature, and the latency of change from baseline to highest temperature, and the latency of change from the beginning of cooling imagery to lowest temperature. Results indicated that the age regression group achieved significantly warmer temperatures than the control group and that the age regression group remained significantly warmer than the two other groups during the cooling imagery. Results also indicated that these skin temperature responses generalized to the nondominant hand. The data were interpreted as suggesting that those subjects exposed to the age regression procedures may have been more relaxed than the other groups. Another interpretation suggested the cooling imagery may not have been accessing common or pleasant experiences of the subjects.

Differences Between Levels of Oral Communication Apprehension and Communicator Style of Preservice Teacher Education Students
The classroom communication behavior of preservice teacher education students was the focus of this research. The study was designed to provide descriptive and empirical data for teacher educators to use in designing preservice and in-service training in classroom communication. Additionally, an interdisciplinary focus on research from the fields of interpersonal and instructional communication as applied to teacher education was emphasized. The sample for the study included 30 secondary and 29 elementary preservice teacher education students. The sample was stratified on the basis of the level of communication apprehension. A total of 30 high level apprehensive and 29 low level apprehensives were identified. The Personal Report of Communication Apprehension-24 (PRCA-24) was administered as a pre-posttest measure. Scores from the Communicator Style Measure (CSM) were analyzed with the PRCA—24. University supervisors and public school cooperating teachers completed a modified version of the CSM on two separate observation occasions.
