Drug-induced tardive dyskinesia, an irreversible involuntary movement disorder caused by neuroleptic drugs, may reflect cholinergic hypofunction in the corpus striatum. Therapeutic results have been reported in trials of choline and lecithin, nutritional substrates which may enhance cholinergic neurotransmission. Lecithin's effects on dyskinetic symptoms were examined in 50 male patients in a double-blind, placebo-controlled trial. Patients were randomly assigned to treatment or control groups; 31 patients were retained in the analytic cohort. Experimental patients were treated with 60 gm/day lecithin (55% phosphatidyl choline) for 11 days. Symptom frequency was rated from videotapes made at baseline, 3 and 11 days of treatment, and 1 week follow-up.

Autotomy (self-induced loss) of body parts has evolved independently as a predator defense mechanism in several major animal phyla. The mechanism among vertebrates, including 13 of the 20 recognized lizard families, is tail autotomy. Its occurrence among the majority of lizard families offers an excellent opportunity to examine the effects of a major selective force on the ecology and evolution of a group of organisms. The research of this study was designed to examine experimentally (i) the function of tail autotomy, (ii) the function of autotomized tail movement, (iii) the energetics of autotomized tail movement, and (iv) the energetic costs of autotomy of an energy-rich tail to reproduction.

The Stammbueh or album of Johann Stobaeus, MS Sloane 1021 in the British Library, is dated January 8, 1640. Stobaeus, its owner, was Kapellmeister in Konigsberg, East Prussia. The album contains 164 pieces for ten- or eleven-course lute, including dances, secular pieces with generic titles, and settings of chorale tunes. Other major material includes two short sets of lute instructions; instructions for singers of liturgical music; poems by members of the Komgsberger Diahterkre's; and short rhymes and epigrams, many of which concern the lute. The dissertation presents a complete modern edition of the lute music and lute instructions, with commentary; biographical data concerning Stobaeus, with background material about Konigsberg and East Prussia; a selection of poems and epigrams, featuring all poems concerning the lute; and commentary on the literary material, especially the evidence it provides that the manuscript might have been compiled in its entirety around the written date of 1640, even though the music is old-fashioned.

The classical normal curve approximation to cumulative hypergeometric probabilities requires that the standard deviation of the hypergeometric distribution be larger than three which limits the usefulness of the approximation for small populations. The purposes of this study are to develop clearly-defined rules which specify when the normal curve approximation to the cumulative hypergeometric probability distribution may be successfully utilized and to determine where maximum absolute differences between the cumulative hypergeometric and normal curve approximation of 0.01 and 0.05 occur in relation to the proportion of the population sampled.

George Kelly has stated that persons place interpretations, or constructs, on what they perceive. Past research has indicated that subjects more meaningfully apply their own personal constructs to persons and situations than constructs supplied from other sources. This study attempted to confirm previous findings. Sixty-three university students used their own personal constructs, elicited from the Role Construct Repertory Test, and supplied instrumental-expressive role constructs to interpret and rate 12 actors portraying instrumental and expressive behaviors in six videotaped scenes. The purpose of this study is to compare the meaningfulness to subjects of stereotypic terms in a sex-role inventory to the meaningfulness of the subjects' own personal constructs when interpreting typical masculine- and feminine-typed behavior.

During the past 80 years, similar descriptions of a hyperactive behavior pattern in children have appeared in medical, educational, and psychological literature. Hyperactivity has been conceptualized as a character disorder, an organic disorder, and, most recently, as a behavior disorder. In this study, hyperactivity was explained in interactional terms, using Rotter's social learning theory of personality. Little consideration has been given in research to the influence of an abnormally high activity level upon personality development during childhood. The purpose of this study was to investigate the general influence of negative interactions associated with hyperactivity upon the organization of four personality constructs: locus of control, self-esteem, trait anxiety, and state anxiety.

A series of picosecond excite-probe experiments was performed on various concentrations of aqueous and ethanolic solutions of rhodamine B in order to determine the existence of dimerization in those solutions. The goals of the research presented in this dissertation were twofold. Initially, various techniques of time-resolved spectroscopy were to be employed to further characterize the ground and excited-state molecular properties of the aqueous RB dimer. The information obtained, and the techniques developed in that study would then be utilized in an effort to secure evidence which would support or refute the claims of rhodamine B dimerization in an ethanolic solution.

This work examines the synthesis of poly(ADP-ribose) in normal and SV40-transformed monolayer cultures of 3T3 cells as a function of growth and DNA fragmentation. A review of the relevant literature is given in the introduction of this work. Poly(ADP-ribose) synthesis has been implicated in transcription, replication, repair, differentiation and regulation of cell growth. The results of this study suggest that poly(ADP-ribose) synthesis is involved in some aspect of cell-growth control and DNA repair.

The reaction of chlorodimethylvinylsilane with tertbutyllithium was investigated in the presence of several conjugated dienes. In all cases except with 2,5-dimethylfuran, [2+4] cycloadducts of a silene intermediate are obtained in hydrocarbon solvents. The presence of THF in the reaction mixture suppresses the formation of cycloadducts in favor of 1,3-disilacyclobutanes. In the reaction of dimethylethoxyvinylsilane or dimethylmethoxyvinylsilane with tert-butyllithium the main product is the 1,1-dimethyl2-neopentyl-4-(dimethylalkoxysilyl)silacyclobutane. It is concluded that lithium chloride elimination to give silene intermediates occurs in hydrocarbon solvents. In the presence of strong Lewis bases or when the leaving group on silicon is an alkoxy group, the addition reaction giving a-lithiosilanes occurs and products arising from their coupling reactions are obtained.

The Lecture Recital was given on July 28, 1981. Its subject, Carl Reinecke's "Undine" Sonata, is a major work written for flute during the nineteenth century. Reinecke was highly respected as a conductor and pianist; his great love for the classical style tempered his Romanticism and conditioned his approach to both performance and composition. The subtitle of the sonata suggests a program based on Friedrich de la Motte Fouqué's short novel, Undine. Although few flutists are familiar enough with this tale to recognize its application to the sonata, an exploration of the program implied by the subtitle adds materially to an understanding and appreciation of the work; to a large extent, the content of each movement is conceived in terms of the program. Further examination of Reinecke's life and philosophy reveals that both the choice of this particular literary subject and the uniting of Romantic pictorialism with classical form were entirely characteristic of his writing. Since Reinecke specified no program other than the subtitle, any relating of the music to specific events in the story is necessarily a subjective postulation. The musical content of the work makes it fairly easy to establish a broad correspondence between the movements of the …

The purposes of this study were to assess the organizational climate of selected elementary and secondary attendance centers in Texas and to determine if there is a relationship between certain variables and the openness of the climate in these attendance centers. The variables considered in this study were: 1. the length of a principal's incumbency; 2. the age of a principal; 3. the size of the professional staff; 4. the departments of instruction in secondary attendance centers; 5. the grade levels of instruction in the elementary attendance centers. All public school districts in Texas with an average daily attendance of 5,000 or more were included. Random selection was used to determine the sample of districts to be included. A stratified sample of seventy-five attendance centers was then chosen. The Organizational Climate Description Questionnaire was administered. A correlational study design was used utilizing pearson-product moment statistical techniques.

The problem of this study is faculty attrition and role strain reported by faculty members in baccalaureate and higher degree programs in nursing. The purpose of the study is to determine whether variations exist in role strain reported by faculty members and faculty attrition based on institutional size, structure, and complexity, and on official expectations for faculty members. A questionnaire eliciting information regarding faculty attrition was mailed to seventy-five randomly selected administrators of baccalaureate and higher degree programs. Data related to faculty role strain were collected by questionnaires mailed to two hundred fifty randomly-selected faculty members from participating schools. Sixty-three administrative questionnaires and one hundred ninety-five faculty questionnaires were returned in usable form and were included in the analysis of data.

The purposes of this study were to determine whether school board presidents' perceptions regarding competency-based testing in Texas were related to the (1) size of the school district represented by those surveyed, and (2) length of service of the board presidents. The dissertation includes an introductory chapter, a review of related literature, the procedures for collection and treatment of data, the presentation of data, and the summary, conclusions, and recommendations.

The problem of this study was to make short-term projections of student semester credit hour enrollments, at each of two state universities of comparable size, based on traditional time series analysis. 1. The first purpose of the study was to identify the cyclical component of deseasonalized enrollment data. 2. The second purpose was to determine a cyclical economic indicator having a high correlation with the cyclical component of the enrollment data. The selected economic indicator was used in establishing explanatory equations for projecting enrollment. 3. The third purpose was to compare projected 1979- 1980 academic year enrollment figures obtained from explanatory equations for each institution with actual enrollment figures of each institution for that year. 4. The fourth purpose was to compare the explanatory equations developed for the two institutions and the projections of student semester credit hour enrollments they yielded. 5. The fifth purpose was to discuss enrollment projections for each institution and the uses of enrollment projections in planning.

The three recitals consisted of performances of original twentieth century solo works for trombone with the exception of two trombone quartets, Adagio, by C. Saint-Saëns, arranged by Ken Murley, and Sonata by Daniel Speer. The lecture recital establishes the position of Kazimierz Serocki (1922-1981) as a major composer not only in Poland but in the rest of the world as well. His many works cover a wide spectrum of styles and genres. The solo trombone works, in particular, are among his most often performed works from his early neoclassic period. The lecture is also an attempt to illuminate the role of neoclassicism in Poland through a brief discussion of Polish neoclassicists, Grażyna Bacewicz and Michael Spisak, and other composers before and after World War II including Constantin Regamey and Roman Haubenstock-Ramati. An analysis of the two solo trombone works, Sonatina and Concerto, shows the technique of composition used by Serocki and the demands placed upon the performer by the music. These works were among the first in a growing list of works for solo trombone composed in response to the notable lack of large scale works of quality for solo trombone during the early twentieth century. The high quality of …

Since the development of the understanding that the electron distribution within a molecule is chiefly responsible for its properties and behavior, factors influencing this charge distribution have been of interest to scientists. The chemical reactivity of a molecule, the physical properties, and to a large extent, structure and geometry, are all functions of the electron distribution. This study examines the issue of electronic structure from two points of view, each of them focussing on a specific component within the molecules studied. In the present work, the effects of the highly polar carbonyl group on spectroscopic parameters and physical behavior are investigated. An additional area of study is the effect of fluorine substitution on the energy levels of some halogenated ethylenes. The specific parameters examined are the ionization potentials, the absorption frequencies, and the energies of a class of excited states known as molecular Rydberg states. It was during the study of these halogenated ethylenes that the observations leading to the carbonyl compound investigations were made, so that the two areas examined are connected both experimentally and chemically.

The problem with which this investigation is concerned is that of determining the degree to which fiscal disparity in Texas school districts affects debt service, as well as maintenance and operation and local enrichment. This study has four main purposes: to determine whether the poor school districts are exerting more or less effort for debt service, maintenance and operation and total taxation than are the wealthy districts; to determine how the size of Texas school districts is related to district wealth; to determine the number of Texas school districts that do not levy a tax for debt service; and to provide information for persons interested in school finance matters—namely, legislators, educators, students of finance and lay citizens who may or may not be property taxpayers.

This study is concerned with determining the role, responsibility, qualifications, and changing trends regarding the position of chief financial officer in higher education : institutions as perceived by presidents and chief financial officers. After a comprehensive review of the literature, a questionnaire was developed, validated, and sent to the presidents and chief financial officers of 100 private and 100 public institutions which had randomly been selected. One-hundred seven presidents and 117 chief financial officers returned the completed questionnaires which produced data upon which the findings of the study are based.

The purposes of this study were to identify the teaching concerns expressed in their early years of teaching by the graduates of the Early Childhood Education program in a church related teacher education institution, and to determine the relationship between teaching concerns and the variables of years of teaching experience and grade level taught.

The lecture was given on July 27th, 1981. The discussion dealt with two anonymous eighteenth-century works: a Symphonia, Anon. 32b in D for two trumpets, two oboes, two violins, viola and bassoon; and a Concerto, Anon. 3 in D for trumpet, three oboes, and two bassoons. Both works are from part-books, originally owned by the Prussian General Georg von Lilien (1652-1726), which are now part of the "Sonsfeld Collection" housed in the Bibliotheca Furstenbergiana at Schloss Herdringen, W. Germany. The lecture included an examination of the origin of the manuscripts, the historical background for the works, and aspects of mixed style in the music. It also contained an analytical discussion of each work. Both works were then performed. In addition to the lecture recital three other recitals of music for solo trumpet were given. The first recital was given on November 21, 1977 and included the Concerto for Trumpet by Johann Nepomuk Hummel, and works of Henry Purcell, Halsey Stevens, and Eugene Bozza. The second recital was presented on July 3, 1978. It featured the Concerto in A('(FLAT)) by Alexander Arutunian along with works of Georges Enesco, Jean Rivier, and Allen Molineux. The third recital included works of Ernest Bloch, …

Training programs designed to remediate eating deficits of higher level patients have involved some combination of verbal instructions, manual guidance, modeling, and reinforcement. Training methods which incorporate relaxation and imagery to facilitate behavior change have received little attention with this population. The current study was designed to explore the use of relaxation and suggestions as a training strategy to modify the shoveling behavior of moderately and mildly retarded institutionalized clients. Three treatment methods, relaxation-suggestion with reinforcement, modeling-instruction with reinforcement, and relaxation-suggestion alone, were compared. A greater reduction in shoveling behavior was hypothesized for the modeling-instruction with reinforcement group than for either of the relaxation-suggestion groups, and a greater reduction in shoveling behavior was hypothesized for the relaxation suggestion with reinforcement group than for the relaxation-suggestion alone group.

The Internal Revenue Code invokes the concept of reasonableness as the major qualification for the stockholder executive compensation deduction for federal income tax purposes. However, neither the Code nor Regulations contain general guidelines for determining reasonable compensation. Consequently, disputes with the IRS are frequent, resulting in substantial litigation. The primary hypothesis of the study was that the IRS guideline variables were incapable of discriminating taxpayers who have won litigated reasonable compensation cases from those who have lost. The secondary hypothesis was that the IRS guideline variable group, the court case variable group, or the two groups combined were equally powerful in discriminating taxpayers who have won litigated reasonable compensation cases from taxpayers who have lost. The study included all unreasonable compensation cases litigated in the Tax Court from 195^ to September, 1980. Only cases related to the reasonableness of officer-shareholder compensation of closely-held corporations were included.

The problem of this study was to determine the pupil control ideology—conceptualized as a continuum from custodialism to humanism—of principals and teachers in public elementary schools in the province of Sukhothai, Thailand. The instrument, the Pupil Control Ideology Form (PCI Form), consists of twenty likert-type items. Responses to each statement are indicated on a five-point scale, ranging from "strongly agree" (five points) to "strongly disagree" (one point). Scores derived from the PCI Form were used as indicators of respondents' orientation toward the control of pupils in elementary schools of Sukhothai, Thailand. The reliability coefficient of the PCI Form yielded a Pearson Product Moment Coefficient of .91 and .95 when using the Spearman-Brown formula. The instrument (PCI Form) was translated into Thai, validated by six judges who were selected on the basis of their positions and knowledge of Thai education. The reliability of the revised questionnaire was determined by a pilot study (test-retest technique) which involved twentyteachers and ten principals of public schools in Sukhothai, Thailand. The results of the Pearson Product Moment Coefficient gave the correlation of .87 and .93 using the Spearman-Brown formula.

The purposes of this study were: (1) to present data resulting from an analysis of the ninety-seven published grievance-arbitration awards involving issues of racial discrimination occurring between April 1, 1974, and December 31, 1980? and (2) to determine from the data how labor arbitrators have reacted to Alexander v. Gardner-Denver Co., 415 U.S. 36 (1974) . The Supreme Court held that labor arbitration was a "comparatively inappropriate" forum for the resolution of employment discrimination disputes. However, the Court said that an arbitral award could be "accorded great weight" by a lower court when certain relevant factors are present in an award. The cases were analyzed to determine the extent to which arbitrators responded to the factors set forth in the Gardner-Denver decision.
