The purpose of this work is to make a contribution to the chamber orchestra literature which employs both traditional and contemporary elements, textures and styles.

This study examined the effectiveness of strategic planning systems in strategy formulation in a changing business environment. It also investigated differences in the designs, processes, levels of top management involvement, and perceived levels of achievement and performance of the strategic planning systems of companies classified as leaders, challengers, followers, and nichers in the electronic computing equipment community. For the most part no significant correlations were found between perceived levels of achievement and performance of planning systems and organizational performance measured by financial ratios. However, significant correlations were found between perceived level of achievement and performance and the design, process and level of top management involvement in the strategic planning process.

The degree of formalization of collection development(the dependent variable) in selected medium-sized academic libraries and six independent variables believed to be related to the dependent variable were examined. The formalization of collection development was measured by an index of five dimensions. The six independent variables examined were age of the library, number of graduate degrees offered by the parent institution, estimated years of growth potential in terms of available shelf space, attitude of the library director toward cooperation, number of memberships held by the library in cooperative endeavors, and percentage of increase in the materials budget, from 1972 to 1982. The findings of this study fail to support hypotheses one, three, four, and six. The relationship between the number of memberships in cooperative endeavors (hypothesis five) is weak, but significant. Hypothesis two is not supported when the total group is considered, but it is supported only when publicly-supported libraries are considered. A positive relationship between size of collection and level of collection development formalization was found to be significant, as was the relationship between number of graduate degrees and size of collection.

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.

The ability of various subsets of human mononuclear cells to produce human lymphotoxin (LT) was examined. Peripheral blood mononuclear cells were seperated into OKT4+. OKT8+ and Leu-lla+ subpopulations by flow cytometry.

Enzymatic activity has been identified in cultured cells which catalyzes the removal of intact mono(ADP-ribose) residues which are bound to protein at arginine. Other activities have been detected which catalyze the removal of ADP-ribose via the sequential removal of AMP and ribose-5-phosphate.

The effect of ribavarin (1-β-D-ribofuranosyl-1,2,4-triazole-3-carboxamide), a synthetic nucleoside, on a series of cellular properties which characterize the transformed state was studied using normal rat kidney cells (NRK) and cloned derivatives transformed by a wild type avian sarcoma virus, B77-NRK, and by a temperature-sensitive mutant of the virus, LA31-NRK.

Investigators have suggested that opiate peptide hormones released during exercise stress may play an important role in athletic performance or perceived effort. Their enzymatic inactivation in the periphery is of considerable interest since the opiate peptides may be regulated by enkephalin hydrolyzing enzyme (EHA). In this study, the relationship between maximal aerobic capacity (VO_2max) and EHA activity was examined in two distinct fitness groups. When the metabolic capacity was evaluated in whole blood, the unfit subjects metabolized the peptides significantly faster than their fit counterparts. Since the total enzyme activity of the two groups is similar, the difference in metabolism must result from circulating factors in the trained athletes, which slow the rate of peptide inactivation.

Few studies in the sporting realm have been conducted to verify the findings from industrial or organizational settings regarding the strong positive motivational effects of goal setting (Locke et al., 1981). Therefore, the purpose of the present investigation was to determine the effects of three levels of goal difficulty and two levels of feedback on the performance of males undertaking an endurance task. Performance results were analyzed using a 2 x 3 x 2 (feedback x goal difficulty x trials) ANOVA with repeated measures on the last factor. Results indicated a significant goal by trials interaction with both specific difficult goal groups improving from trial one to trial two. The "do best" group showed no significant improvements. It was also found that only the difficult, but not the extremely difficult goal group performed significantly better than the "do best" goal group. No significant differences were found between the two feedback groups. The results are discussed in terms of Locke's (1968) original theory of goal setting.

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.

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.

A model was developed to predict the increased physiological effort of wearing a respiratory protective device. Specifically, the model was designed to predict the effects of varying ventilatory demands on eleven respiratory variables of the man-respirator system, breath frequency (f_b), tidal volume (V_t), inspiratory flow (dvi/dt), expiratory flow (dve/dt), inspiratory mask pressure (P_mi), expiratory mask pressure (P_me), inspiratory intrathoracic pressure (P_ii), expiratory intrathoracic pressure (P_ie), inspiratory mask work (W_mi), expiratory mask work (W_me), and mask leakage index (L_i). The model was tested by experiment in which three male subjects underwent maximal exercise testing with and without the "pressure-demand" respirator. The eleven variables were determined for each thirty second period utilizing on-line computer analysis. Application of the model to these experimental conditions resulted in significant (p<.001) relationships between each of the predicted and observed variables.

Periodic fluctuations in women's emotions during the menstrual cycle have been a continuing topic of research and discussion. The current study was designed to determine if premenstrual syndrome conditions in female teachers have any effect on reported classroom misbehavior and infractions. Subjects were twenty-one faculty members presently employed in the capacity of teachers in a public middle school. By utilizing a teacher's daily behavioral checklist, along with student misconduct reports, the changes in teachers' moods and behavioral symptoms over the menstrual cycle were studied in relation to reported student infractions. Based on the results of this study, it appears that menstrual cycle fluctuations have no recognizable impact upon a female's classroom demeanor and her ability to discipline in a professional manner.

(1). An improved method for synthesizing bicyclo (2,2,1) hepta-2,5-diene-7-spiro-1'-cyclopentane (5) has been developed. Thermal reaction of compound (5) with neat iron pentacarbonyl under nitrogen atmosphere affords the corresponding cage dimer (6). Some aspects of the syntheses, spectra, and chemistry of compound (5) and (6) are discussed. (2). A structure isomer of decamethyldodecahedrane (C₃₀H₄₀), molecule (11), is expected to be synthesized via thermal reaction of iron carbonyl complexes with compound (10). An intermediate in this synthesis, 2,2- tetramethylene-1,4-dibromobutane (9) was efficiently synthesized starting from cyclopentanone. Some aspects of the syntheses, spectra, and chemistry of compound (1) to (9) will be discussed.

The problem with which this investigation is concerned is determining the viability of economic development in the oil and natural gas sector in Bahrain since its independence in August 1971, and the changing role of the government in shaping oil policies and managing downstream operations. This inquiry emphasizes the importance of cooperation and coordination in the oil industry among the Arab Gulf States. This study concludes that Bahrain's economy is passing through and era which will have one of two possible endings: one will protect the independence of the country and promote cooperation with the other Arab Gulf States as a transitional stage toward a board regional unity; the other will lead Bahrain to become a commercial outlet for Saudi Arabia.

Three suspended solids types containing a range of physicochemical characteristics were used to determine the effect of suspended solids on the bioavailability of acenaphthene, 1,2,4,5-tetrachlorobenzene, zinc, and chlordane to Daphnia magna and Pimephales promelas. Generally, the bioavailability of zinc and chlordane decreased due to interactions with all suspended solids types while bioavailability of acenaphthene and 1,2,4,5-tetrachlorobenzene were not clearly reduced. Partition coefficients and slope of dose-response curves related chemical characteristics and organism sensitivity, respectively, to experimentally determined results. It is believed that the biologically available form of these chemicals to Daphnia magna and Pimephales promelas resides in the aqueous phase.

This thesis examines the struggle between King Louis XI and the great feudal houses of the fifteenth century such as Burgundy, Brittany, Anjou, Armagnac, Bourbon, and Foix. It attempts to provide a detailed narrative based on the primary sources and the excellent studies on individual feudal princes produced by a number of French historians, supplemented by a critical analysis of the traditional view of Louis XI as the "vainquer de la grande féodalité."

The present study examined the impact of gender and sex-role orientation on therapy effectiveness. Previous research suggested that same-sex pairings and androgynous therapists would be most desirable. Interviewers (therapists) were 25 male and 15 female third-year doctoral psychology students, each interviewing a male and a female undergraduate student (client). Results did not support the hypothesis that gender and sex role were powerful predictors of therapy effectiveness. However, this study did find that therapist self-rated interpersonal competency and accurate self-perception predicted therapy effectiveness for female clients. Therapists' consistency in using various parameters (techniques) of therapy was related to client perceived effectiveness. Opposite-sex pairings were less likely to result in momentary feelings of discomfort during initial interviews.

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.

Seamus Heaney's 1979 volume of poems, Field Work, contains ten sonnets written while the Northern Irish author lived for four years in a nineteenth-century cottage near Dublin. These sonnets, dealing with art, language, nature, and politics, reflect Heaney's major themes and are typical of his poetic techniques. This study analyzes the content of the ten sonnets as well as their technical aspects.

The study described through content analysis the general music course in the secondary school as perceived in selected curricular sources from the 1960's and 1970's. As various writers of curricular sources developed their own content and methodologies, a vast amount of data became available which seemed unmanageable because of the particular philosophical goals chosen for the course. The study organized in a systematic manner the content and methodologies of the.course by means of eighteen categories. Categories of high frequency inclusion in the general music sources were shown to be the elements of music, music vocabulary as a specific area for learning, the predominant choice of classical Western/art music, the use of listening and creative activities and the discussion of psychological learning principles.

Some men are born to greatness, others to great tragedy. This novel is a fictional account of one of those men: the notorious Texas outlaw, Sam Bass. Set in the Old West of the 1870s, the story primarily concerns itself with events in the train robber's life from the time he owned and raced the Denton Mare to the now famous shoot-out in Round Rock, Texas. It is a story of crime and betrayal told through the eyes of Bass and one of his close confederates, Jim Murphy.
