Powdery mildew of wheat, Erysiphe graminis f. sp. tritici attacks wheat during periods of rapid growth, high levels of nitrogen fertilizer, high humidities, and cool temperatures. Yield losses due to mildew are caused by reduction in photosynthesis, increase in respiration and transpiration, impairment of heading and grain filling, and loss of plant vigor and growth.

The present investigation attempted to determine whether imagery combined with relaxation (VMBR) facmlitated karate performance more effectively than either imagery or relaxation alone. Each subject (N=30) was randomly assigned to either a VMBR, relaxation, imagery or placebo control condition. Trait anxiety tests were administered at the beginning and the end of the six week test period. Performance tests were administered at the final class period along with precompetitive state anxiety. Trait anxiety results indicated a reduction in trait anxiety for all groups. State anxiety results indicated that the VIYBR and relaxation groups exhibited less state anxiety than the imagery and control groups. Performance results produced a main effect only for sparring with the VMBR group exhibiting better performance than all other groups.

The Taxpayer Service Division contributes to the Internal Revenue Service mission of achieving the highest possible voluntary compliance with the Federal income tax law by answering questions and helping taxpayers in their return preparation efforts. These services are provided by Taxpayer Service Representatives and Taxpayer Service Specialists (TSS's). The TSS position was established in 1975 to upgrade the quality of assistance provided. TSS duties include being able to provide assistance with problems involving complex areas of the tax law. The purpose of the study was to disclose to what extent TSS's are called on to answer tax questions related to partnerships, corporations, and Subchapter S corporations and to disclose whether they have been trained and are able to answer the inquiries.

The purpose of this thesis was to analyze a number of auditor change and other peripheral issues from two related perspectives. Empirical data were gathered from publicly available Forms 8-K and 10-K to first assess whether meaningful differences existed between NYSE, AMEX, and OTC registrants regarding disclosures required in those documents. Secondly, the data were analyzed to determine whether differences existed with respect to the accounting firms (Big Eight or non-Big Eight) involved in the auditor changes. In most of the tests designed to achieve these purposes, statistically defensible results were obtained using the nonparametric chi-square test for significance of observed differences and the McNemar test for significance of changes, at the .05 level.

Australia's dual system of broadcasting has provided national and commercial radio services to Australians in both urban and remote areas. Networks were formed to serve these areas, but advertising agencies tended to dominate smaller commercial networks on behalf of their clients. Most of these failed. The Macquarie Broadcasting Service Pty. Ltd. (MBS) network began in 1938 and offered network programming and sales representation to stations affiliating with them. Its subsidiary, Artransa Pty. Ltd., also produced and syndicated programs and provided sales representation both nationally and internationally. This study concludes that MBS' contribution to Australian commercial broadcasting was the development of networking and that it had the greater listenership of any commercial network in this time period.

The investigation is a historical survey tracing the development of Casa Mañana Musicals, Inc., Fort Worth, Texas, from its experimental beginning in 1958 as the first permanent musical arena theatre in the United States, through twenty-three subsequent seasons. The study includes a chapter on the origins of theatre and the influences behind its concept dating back to the 1936 Casa Mañana produced by Billy Rose. Subsequent chapters deal with the theatre's seasons and its struggle to gain acceptance. The theatre's more recent financial and labor problems are also considered. Major sources include such unpublished data as production and financial records of the theatre, contracts, correspondence, minutes of the board of directors, and interviews. Published sources include accounts in newspapers and periodicals.

The purpose of this study was to identify the major problem areas of freshmen community college students and to determine if significant differences in problems of freshmen students existed as a variable of age, sex, or marital status. The population consisted of 674 community college students enrolled in an Orientation to College program during the fall or spring semester of 1976, 1977, 1978 or 1979. Each student was administered the Mooney Problem Check List (MPCL), College Form (1950) during the first week of enrollment at the community college. he data were analyzed in order to determine if a significant difference existed in the problem areas reported by students according to a Friedman Two-Way Analysis of Variance by Ranks. A significant difference produced by the Friedman ANOVA indicated a need to apply a Wilcoxon Matched-Pairs Signed Ranks Test in order to determine which problem areas differed significantly from one another. A Mann Whitney U Test was employed to statistically compare the problem areas of male students and female students as well as married students and single students. A Kruskal-Wallis one-way analysis of variance by ranks for k independent samples was employed to test differences in the responses of four student age …

This research study was designed to investigate the relationships of imagery, self-concept, anxiety, stress, subjective stress and seriousness of illness and to determine the potential of certain cognitive mediating variables, especially imagery and an interaction between self-concept and imagery, to significantly increase the efficiency of stress as a predictor of seriousness of illness. The purposes of this study were: (1) to determine the efficiency of stress as a predictor of disease, (2) to determine if cognitive mediating variables will significantly increase the predictive efficiency between stress and disease, (3) to investigate selected correlations among the variables, (4) to provide a research base for current treatment procedures using imagery treating various illnesses.

This study describes the learning projects of a sample of engineers between the ages of 25 and 35 employed by a single employer in Port Worth, Texas. The problem of this study was the nature and extent of the continuing education programs of young engineers and the implications of these programs to their job requirements and possible employer assistance. The purposes of this study were to determine the number and types of learning projects undertaken each year by engineers with degrees, the number of hours spent by the subjects, the problems experienced, the resources used, the amount of job-related learning projects undertaken, the locations used to pursue learning projects, and whether the learning projects were amenable to assistance from employers.

The purpose of this work was to examine the effect of the use the assumption κω2K/ΕCM «1 in calculating K-shell ionization cross sections in the plane wave Born approximation (PWBA) where κω2K is the observed binding energy of the K-shell and ECM is the energy of the incident particle in the center of mass system. Avoiding this assumption produces a threshold for ionization at Ecm = κω2K. Calculations employing the assumption, which leads to the use of approximate limits of integration, do not go to zero for even the .Lowest values of the incident energy.

This paper investigates Henri Murger's novel, Scenes de la Vie de Bohème, as a model for the opera composed by Giacomo Puccini La Bohème. Colleen Hughes Mallette discusses the historical background of the works and examines the music and story.

The problem of this study was to compare the expectations of the interior design profession regarding entry level requirements of new graduates of Southwest Texas State University and the present interior design curriculum at Southwest Texas State University. Questionnaires seeking information regarding skills and knowledge thought necessary for graduating interior design students were sent to professional interior designers in the South Texas area. Simple descriptive statistics were used to analyze the responses. The survey of the interior designers practicing in the South Texas areas conducted in this needs assessment of the Interior Design program at Southwest Texas State University supports giving consideration to the development of new courses or content revision of existing interior design courses offered at Southwest Texas State University.

The neo-classic movement in Italy, which gained momentum in the early 1920's, was rooted in an instrumental style patterned after that of the Baroque era. The term "new classicism," proposed by Ferruccio Busoni in 1920, represented a reaction against the extreme chromaticism and large performance forces of the late nineteenth century. The pianistcomposer Alfredo Casella, after earlier periods in which he was influenced by such diverse composers as Mahler, Debussy, and Schoenberg, soon became the chief spokesman for the neoclassic movement in Italy. Casella considered the Sinfonia, Arioso and Toccata his most important work for the piano, because of its size and musical content. It is notable for its usage of thematic transformation, much of which is based on the interval of a fourth or fifth. This study includes a formal outline of each movement, showing sectional divisions and tonal regions, as well as illustrations of thematic transformation and intervallic patterns. Also discussed are the work's neoclassic style characteristics, including counterpoint, pandiatonicism, modality, and linear cadential treatment.

The forty-one poems comprising this thesis are written in a variety of styles and reflect my general international eclecticism. The most prominent influences on my work are ancient Chinese verse, as exemplified by the poems for N., and Zen tanka and haiku, as exemplified by "Detail from a Cubistic Autobiography." Largely imagistic rather than narrative, the poems were conceived in an effort to record my experiences and to define my reactions to those experiences.

Sixteen Nerodia rhombifera were used in each of two experiments investigating operant conditioning of the tongue flicker response. A yoked pair design was utilized throughout phases of baseline, continuous reinforcement, partial reinforcement, and extinction. During partial reinforcement, one-half of the experimental animals were reinforced FR-4 and the other half were reinforced continuously. Control subjects were treated as were their experimental partners, with the exception of noncontingent reinforcement. Statistical comparisons between means for groups during the CRF phase, partial reinforcement phase, and extinction phase were nonsignificant. However, because some snakes in the experimental groups appeared to show increases in response rate during CRF and FR conditions, the possibility exists that modification of task parameters will produce positive results in future research.

The problem with which this investigation is concerned is the design of a model for student follow-up procedures. This model is based on an analysis of the opinions of community junior college experts on the language and characteristics of a student follow-up system. This study has a twofold purpose. The first is to determine a consensus from the responses of experts on public community junior colleges regarding the important definitions, terminology, and characteristics of a student follow-up system. The second is to develop a model that can be implemented for student follow-up investigations.

The problem of this study was that parental perceptions of the roles and needs related to their children's reading development had not been successfully investigated. The primary purpose of this investigation was to determine parental perceptions of their roles, influence, and skills most needed to assist them relating to their children's reading development; the information sources on which parental beliefs about their role are founded; factors foreseen by parents that might hinder their involvement in that role; parents' preferred mode of receiving desired information relative to their assistance in their children's reading development; and existing variations in parental perceptions.

The present study translated the major theories of obesity into physiological terms, then tested for the ways these theories might find physiological expression. Theoretical positions included the psychoanalytic perspective, emphasizing intrapsychic processes; psychosomatic perspective, emphasizing food as an anxiolytic agent; and Schachterian perspective, emphasizing heightened sensitivity to external stimuli. Additionally, two classificatory distinctions, age at onset of obesity and extent of dietary restraint, were examined. The later distinction suggested that Schachterian findings on obese behavior were due not to obesity, but to a dieting life style.

A variation of the excite-and-probe technique is used to measure the picosecond evolution of laser-induced transient gratings that are produced in germanium by the direct absorption of 40 psec optical pulses at 1.06-μm. Grating lifetimes are determined for free carrier densities between 10¹⁸ cm⁻³ and 10²¹ cm⁻³ . For carrier densities less than 10¹⁹ cm⁻³ , a linear diffusion-recombination model for the grating provides a good fit to the experimental data and allows the extraction of the diffusion coefficient and an estimation of the linear recombination lifetime. Above carrier densities of approximately 10²⁰ cm⁻³ , the density dependence of the diffusion coefficient and nonlinear recombination processes must be considered. Numerical solutions to the resulting nonlinear partial differential equation are obtained that allow extraction of information concerning the high density diffusion coefficient and the nonlinear recombination rates.

The assertive training literature has documented the effectiveness of both behavioral and cognitive methods to increase individual's assertiveness. However, the ability for such methods to enhance the generalization of treatment effects to untrained assertive response classes and the natural environment has been poor. In addition, little notice has been paid to the durability of these changes. Although the past several years have witnessed more intensive efforts by investigators to program generalization as part of their interventions, results have continued to be disappointing. A specific generalization-enhancing treatment strategy, self-directed practice, has been utilized with much success in phobic populations. This strategy, and the theoretical orientation it reflects, has been proposed for use in assertive training. The present study sought to examine the effectiveness of this method as compared to the traditional assertive training procedures and investigate the role of self-efficacy expectations in mediating initial behavior change and its subsequent generalization.

This study investigated the psychobiological and pacing characteristics of the 1.5 mile run. Sixty-six males (18-27 years) performed the run, and were monitored for ratings of perceived exertion, heart rate and split times. The perceived exertion values increased in a near-linear fashion inconsistent with other measures, and thus are not considered a supportable indicator of physiological performance during the run. Pace was characterized by an initial sprint that slowed to a near-steady pace and concluded with a final sprint. The initial and final sprints were most highly related to the variance of performance time. Initially, heart rate accelerated greatly. This acceleration slowed, ending in near-maximum heart rates. The data suggested that performance may rely heavily upon anaerobic mechanisms, and that variance in previously reported correlational analyses of VO2max and 1.5 mile run performance times may be somewhat due to anaerobic mechanisms.

In this dissertation I argue that in the characters in Lawrence Durrell's The Alexandria Quartet there is consistently evidenced a psychological orientation towards growth. An introductory Chapter One surveys and a concluding Chapter Six summarizes the dissertation, but the body of the text is four chapters demonstrating the growth-orientation in four characters.

The first objective of this investigation was to conduct a systematic study into the reactions of chloroketenes with ketene acetals. The second objective was to explore the synthetic utility of these reaction products and offer a rational explanation for these reaction products.
