Concertino for Orchestra
Concertino consists of two movements, Paean and Dithyramb, either of which may be performed independently. Paean, a work of calm and majestic intensity, is characterized by a rhythmic pulse which is more consistently regular than that of the Dithyramb. Its three major sections form an arch, the final measures (mm. 87-95) returning to the material of the opening (mm. 1-14). The first section begins quietly, Maestoso ma sostenuto, in a very slow tempo. The activity and intensity increase until a brief, more active middle section begins in a faster tempo (Ancora piu mosso, m. 55). A fff climax (m. 63) begins in the third section (Tempo I). After a brief poco piu mosso (mm. 72-81), the opening tempo is restored (m. 82), the opening material returns (m. 87) and the final chord fades away. Dithyramb is a free and dramatic movement in which the musical material of the wind group usually contrasts with that of the string group. The piano, which has its own material, occasionally takes on the character of one group or the other as though mediating the conflict.

Strategic Planning Systems their Effectiveness in Strategy Formulation in the Electronic Computing Equipment Industry
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.

Respond Motets from Matins for the Dead by Robert Parsons
The three respond motets from Matins for the Dead by Robert Parsons constitute an important part of the sacred Latin repertory of mid-sixteenth-century England, illustrating central features of the English mid-century style. Although he worked within a conservative musical tradition, Parsons experimented with that tradition in personal and individual ways. Specifically his modal and thematic construction as well as his practice of musica ficta are singled out for closer analysis. Consequently, a methodology for editorial decisions concerning musica ficta is developed. Two special problems, the simultaneous cross-relation and diminished fourth, are shown as the result of normative polyphonic processes and vertical structures.

Depression and Helplessness-Induced Cognitive Deficits Among the Aged
To investigate the impact of helplessness-induction on cognitive performance in the aged, 66 community-residing elderly persons (X=72.5 years) were administered a word association task, disguised as a test of onterpersonal empathy, under a) response independent (RI), b) response dependent (RD) reinforcement, o c) control conditions. The subjects were categorized as either depressed or non-depressed. Three (treatments) by two (levels of depression) by two measurements (pre- vs. post-treatment) ANOVA's were performed on scores from both short term memory and intelligence measures. These suggested that the more depressed elderly demonstrated greater helplessness-induced short term memory deficits, and to a lesser extent, fluid intellectual deficits.

Formalization of Collection Development in Selected Medium-Sized Academic Libraries
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.

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.

Perspectives on the Musical Essays of Lorenz Christoph Mizler (1711-1778)
This study provides commentary on Mizler's Dissertatio and Anfangs-Gründe des General Basses. Chapter V is an annotated guide to his Neu eröffnete musikalische Bibliothek, one of the earliest German music periodicals. Translations of Mizler's biography in Mattheson's Grundlage einer Ehrenpforte and selected passages of Mizler's Der musikalischer Staarstecher contribute a sampling of the critical polemics among Mizler, Mattheson, and Scheibe. As a proponent of the Aufklärung, Mizler was influenced by Leibnitz, Thomasius, and Wolff. Though his attempts to apply mechanistic principles to music were rejected during his time, his founding of a society of musical sciences, which included J. S. Bach, Telemann, Handel, and C. H. Graun as members, and his efforts to establish music as a scholarly discipline deserve recognition.

Enkephalin Metabolism in Exercise Stress
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.

The Harambee Movement and its Effects on Kenya's Economic Development
This paper examines the Harambee Movement and how it affected Kenya's economic development. Before 1963 Kenya was a British colony and economic development favored the colonial government. At Independence the new government tried to restructure the economy for the Kenyan people. Recognizing the lack of adequate capital and a rural development program, the movement became a means by which people could provide services for themselves. These services included schools, technical training, water supply and health facilities. Sources of data were books, articles, government publications and papers published by the Institute of Development Studies, Nairobi University. The Harambee Movement flourished in the provision of educational opportunities, clean water supply and health facilities. Problems included planning, coordinating and duplication of services.

The Effects of Goal Difficulty and Information Feedback on the Performance of an Endurance Task
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.

Conformation-Activity Studies of Pyrethroid Alcohols
The synthesis and insecticidal activity of certain alcohols (hydroxymethyldibenzofurans, hydroxymethyldibenzothiophenes and some of their ⍺-cyano derivatives), esterified with trans-chrysanthemic acid, were investigated. The preparation of these planar alcohol moieties was undertaken to study conformation-activity effects in insecticides of the pyrethroid type. The synthesis of final ester products employed two methods. One was the direct condensation of the appropriate alcohol with chrysanthemic acid chloride in the presence of pyridine. The other involved the in situ formation of the cyanohydrin from the appropriate aldehyde and subsequent condensation with chrysanthemic acid chloride in the presence of a phase transfer reagent. Insecticidal activity is to be tested at rates of 0.001, 0.01, 0.1, 10, 100, and 1000 ppm. Fenvalerate is used as the standard against Diabrotica undecimpuntata (spotted cucumber beetles).
