The primary purpose of this study was to investigate how imagery evolved in my work, in dealing with the relationship between body and landscape and the relationship between image and abstraction. Five paintings were created for the investigation of the evolution in my imagery. A journal of notes was kept concerning each piece while in progress and immediately following its completion. The analyzing method was a visual analysis of the structure and content, as well as the process through which the imagery evolved.

The effects of external electric fields (EEF) on brain activity in anesthetized rats were studied. The field strengths used, 9 kV/m and 5 kV/m, both D.C. and A.C. (60Hz) were in the range of those measured beneath current overhead transmission lines. Brain activity was monitored from surface electrodes and from electrodes stereotaxically implanted in the posterior-lateral portion of the hypothalamus. It was found that 9 kV/m and 5 kV/m EEF's both D.C. and A.C. brought about statistically significant changes in hypothalamic activity, however, the effects were bi-directional, (i.e. increases and decreases). Only seven of the 60 animals exposed showed changes in the EEG recorded with surface electrodes. The data clearly indicate that (1) anesthetized animals do respond to a change in the external electric field around them, (2) the hypothalamus may contain special electro-receptors that, in turn, may alter various other physiological processes, and (3) the data indicates the need for further research to help government agencies to establish more adequate safety guidelines.

This paper discusses corporal punishment as a disciplinary method in American public schools. The effectiveness of corporal punishment is investigated. Chapter I introduces corporal punishment as a pertinent educational issue. Chapter II discusses the historical development of corporal punishment. Chapter III discusses the legal ramifications of corporal punishment. Chapter IV looks at surveys and studies that have been conducted in regard to the issue. Chapter V discusses a survey of teachers in Lewisville, Texas. Teachers responded to 42 statements pertaining to corporal punishment. Chapter VI concludes that research indicates that corporal punishment will not be effective unless it is administered harshly and consistently. The paper concludes that corporal punishment will not be necessary if higher educational institutions train teachers in alternative methods.

Rats were trained to discriminate an injection of cocaine, 5.0 mg/kg, from an injection of saline, using a two-lever choice paradigm: one lever was correct after cocaine injection, the other lever was correct after a saline injection. After training, cocaine and methamphetamine were generalized to the cocaine lever, but phenethylamine (PEA) was only partially generalized. Cocaine was injected every 8 hrs, 20.0 mg/kg, and the discriminability of 5.0 mg/kg was tested every other day. Redetermination of the cocaine generalization curve after 6 days of chronic administration showed a shift to the right, from an ED50 of 4.1 mg/kg in the pre-chronic condition to 10.0 mg/kg. Tolerance did not develop to the behavioral effects of cocaine, measured by time to the first reinforcement and response rate. There was cross-tolerance to methamphetamine; however, no evidence for cross-tolerance to PEA was obtained. Following the acquisition of tolerance, chronic administration of cocaine was terminated, and the discriminability of 5.0 mg/kg was tested every other day for loss of tolerance. After 8 days the ED50 returned to 5.0 mg/kg.

Adult stonefly emergence, nymphal growth, drift and microdistribution were examined in Battle Branch, a secondorder, spring-fed stream, from November, 1982 to May, 1984. Adults of 22 species emerged successionally, with specific adults present every month. Searching emergent objects and the stream margin was best for collection of winter and early spring emerging species. Sweeping the streamside and light trapping were most efficient for late spring and summer emerging species. Nymphal growth for nine abundant species generally fit double log or semilog models. Drift was low, but did show a post-sunset pulse. Generally, leaf material was found to be significantly related (p<O.001) to density, diversity and biomass of stoneflies in Battle Branch.

An environmental evaluation concerning land designated for park and recreation development was conducted in Flower Mound, Texas. Results were compared with the findings of a public opinion survey of the citizenry of Flower Mound. The first section is an introduction to land use and recreation planning. Section two presents a review of pertinent literature concerning environmental evaluation and recreation and recreation planning. Third is a brief description of Flower Mound, Texas, and existing park properties. The fourth section discusses both the environmental evaluation and the survey research techniques employed. Results of the environmental evaluation are examined in section five. The public opinion survey results are discussed in the sixth section. Flower Mound is fortunate to have a number of sites suitable for recreational development. If recreational development is to be successful and satisfactory to the users, decisions will need to be made in an organized fashion. Park and recreation planning should be incorporated within a general land use planning framework.

The principal theorem of this thesis is a theorem by Peano on the existence of a solution to a certain integral equation. The two primary notions underlying this theorem are uniform convergence and equi-continuity. Theorems related to these two topics are proved in Chapter II. In Chapter III we state and prove a classical existence and uniqueness theorem for an integral equation. In Chapter IV we consider the approximation on certain functions by means of elementary expressions involving "bent line" functions. The last chapter, Chapter V, is the proof of the theorem by Peano mentioned above. Also included in this chapter is an example in which the integral equation has more than one solution. The first chapter sets forth basic definitions and theorems with which the reader should be acquainted.

Wretlind, Heden, and Wadstrom found ammonium sulfate to be inhibitory for the formation of extracellular protease in Aeromonas hydrophila grown in Brain Heart Infusion medium. They demonstrated by manipulating the iron and zinc content within their medium that it is possible to differentially affect the accumulation of hemolysin and protease by A. hydrophila grown in batch culture. Further manipulation of the composition of this medium was done in the present study to determine the effect of other components on the production of protease. The purpose of this study was to determine the factors affecting the level of A. hydrophila protease produced in a chemically defined medium.

Etheostoma spectabile, E. punctulatum, and Cottus carolinae were sampled Mar., 1983, - Feb., 1984, in Flint Creek, Oklahoma. Immature E. spectabile ate primarily microcrustaceans, while mature fishes relied more on mayflies and amphipods. Juvenile E. punctulatum fed upon mayflies, amphipods, and Asellus. Mature E. punctulatum ate primarily mayflies, and other relatively larger prey. Cottus carolinae consumed chironomids almost exclusively in Jan. - Feb., 1984, while mayflies were predominant the remainder of the year. No significant habitat partitioning between the two darters, and seasonal habitat segregation between C. carolinae and the two darters was found. Dietary overlap between the darters was significantly correlated (p<0.0005) to differences in x prey sizes.

The present study was designed to investigate the hypothesis that female clients who tend to terminate therapy prematurely will have been assigned to a male therapist. The study also tested the hypothesis that female clients who defect from therapy will have reported a history of low self-disclosure to individuals of the same sex as their therapist. Neither hypothesis was supported by the results of this study, but findings suggest a possible bias in the manner by which male and female therapists select their clients for therapy. It also appears that female defectors may be over-identifying with their family of origin or that they may be overly dependent on it as a resource system. This may be the reason for their apparent difficulty in developing a prototype that will accommodate their therapist.

Relationships between MMPI subscale scores and premature resignations among Southern Baptist foreign missionaries appointed in 1964 were investigated in an effort to develop a predictive model for attrition. Unsuccessful attempts were made at cross-validating the results of a previous related study, and two separate discriminant function analyses were undertaken. The first sorted subjects into three groups, defined by subjects' length of service before resignation. The second classified them according to the reason stated for their termination, if applicable. Both procedures failed to establish a statistically reliable classification system for relating MMPI scores with premature resignations. Although consistent success has been achieved with the MMPI as a screening instrument for psychopathology, it is suggested that the instrument is not adequately sensitive as a screening device for groups lying predominantly within the normal range of variability.

The high concentrations of amitriptyline found in blood at autopsy, indicating a large amount of ingested drug, is often contradictory to the prescription available. Using dogs as the animal model it was found that there was a large variance between the dose given and its plasma amitriptyline concentration during the acute phase of absorption. Factors that were found to be important were the amitriptyline to nortriptyline (as metabolite) ratio, the nature of the specimen, and the collection site. The calculation of the dose from an acute ingestion of amitriptyline resulting in death cannot be accurately determined from a single specimen collected at autopsy.

It was the intention of this project to test selected objects to determine which ones could be used for decoration. If an object became a stable, aesthetically pleasing, part of the glazed piece, then it was considered successful. Two firing temperatures are important to my work; they are 1796 degrees Fahrenheit, oxidation (which is cone 06), and 2372 degrees Fahrenheit, reduction (which is cone 10). I expected some of these objects I chose to work better at the lower temperature, and some to work better at the higher temperature. All objects were test-fired on small plate-tiles at both temperatures. After testing, I decided which items were successful as decorative additions. With these successful objects, I was concerned about what methods of attachment were possible and what surfaces were appropriate.

The primary purpose of the study was to determine if measured LBM could be used as a more powerful predictor of BMR than could surface area (SA) as calculated by the formula of DuBois and DuBois (1916). It was also of interest to develop a prediction equation for BMR using multiple regression analysis. Data from 82 women and 76 men were included in the study. Pearson product-moment correlations indicated that LBM was a better predictor for BMR than SA on either of the principal SA prediction equations, those of Aub and DuBois (1917) and Harris and Benedict (1919). Age, sex, and fat weight were not found to contribute significantly to prediction when included by multiple regression analyses. Linear equations for BMR as a function of LBM were developed for each sex. Tables based on these equations were also generated as a quick reference for clinicians.

This thesis examines the possibilities of social-context issues in interpretation. A group interpretation script relating the current difficult conditions of rural Iowa was compiled. Three experts in the field of interpretation were asked to evaluate the potential of this social-context script. It was discovered that a compiled interpretation script of Iowa literature can successfully depict the social concerns facing the family farms of Iowa.

This investigation explored voice use and perception of use in singers as compared with non-singers at the university. Students recorded the amount and type of their voice use for forty-eight hours. They made judgments about their use and whether a voice disturbance was present. Each student was taped, and tapes were judged for disturbances. It was hypothesized that singers would have greater voice use and awareness than non-singers and experienced singers would have greater voice use and awareness than less experienced singers. Singers used their voices more than non-singers, but there were no differences in awareness. No differences between singer groups were noted. There was a high incidence of voice disturbances in all groups. Suggestions for future research were made.

The purpose of this study was to examine selected mechanical factors involved in the tennis serve. Special emphasis was placed on identifying factors which distinguish players of different serving abilities. Ten right-handed female tennis players, five ranked, and five unranked, were evaluated, following filming with a high-speed camera, on the basis of five good and five fault serves. The ranked players were seen to differ from the unranked players with respect to (a) serving consistency, (b) initial Y-center of gravity values, (c) certain segment angles at the peak of the ball toss and at ball contact, and (d) certain joint angles at the moment of the ball contact.

Dominant genera of bacteria were isolated from three river waters during anthracene and pentachlorophenol biotransformation studies. The genera Pseudomonas, Acinetobacter, Micrococcus, Chromobacterium, Alcaligenes, Azomonos, Bacillus, and Flavobacterium were capable of biotransforming one or both of these compounds. These isolates were subjected to further biotransformation tests, including river water and a basal salt medium with and without additional glucose. The results of these experiments were evaluated statistically. It was concluded that only a limited number of the bacteria identified were able to transform these chemicals in river water. The addition of glucose to the growth medium significantly affected the biotransformation of these chemicals. It was also determined that the size of the initial bacterial population is not a factor in determining whether biotransformation of anthracene or pentachlorophenol can occur.

This study examines the county courthouses of Arkansas with the purpose of discovering certain qualities which they possess as architecture. Stylistic influences are identified, as are influential architects, periods of building activity, and characteristics of age and condition. An historical overview provides information concerning nationwide trends in public architecture over the last century, allowing observations as to the effects which national and regional tastes had on Arkansas' county courthouse builders. It is concluded that Arkansas' county courthouses reflect, to some extent, the stylistic preferences and backwardness of southern and rural courthouses, respectively. The Georgian Revival is identified as the most popular style for courthouses still in use, although the most active building period is found to be the 1930s, when WPA design specifications dominated Arkansas courthouse architecture.

The purpose of this play is to dramatize the charismatic powers of an evangelist, Brother R.T. Bumpass, over his family and his followers. Faced with a challenge from his daughter, Martie, Brother Bumpass manages through a questionable miracle to prove to her that his way offers the only hope and salvation for her life.

This study compared the public relations efforts in three Dallas retirement facilities against suggested standards of professional public relations practitioners to determine which standards each facility utilized. Externally, all three facilities related to the community in an "above average" way, as indicated by their utilization of the twenty-two suggested standards. Internally, two facilities related to residents and staff in a "superior" way, and one facility related in an "average way," as indicated by their utilization of the twenty-two suggested external standards and twenty suggested internal standards. The conclusions drawn from this study are that retirement facility administrators, in general, are not fully aware of the internal and external public relations strategies that could benefit them within the community and with residents.

Concertino for Tuba, Winds, and Percussion is a work for solo tuba and an ensemble consisting of two flutes, two oboes, two clarinets, bass clarinet, bassoon, four horns, two trumpets, two trombones, bass trombone, and three percussionists. The percussionists play small, medium, and large suspended cymbals, triangle, tam tam, metal wind chimes, five tom toms, snare drum, tenor drum, bass drum, two sets of two timbales, five temple blocks, maracas, glockenspiel, vibraphone, chimes, xylophone, marimba, and five timpani. The three movements of the work follow the arrangement of the standard concerto format (fast-slow-fast). The lengths of the movements are approximately four minutes and fifteen seconds, two minutes and twenty-five seconds, and four minutes and ten seconds respectively. The total duration of Concertino is about eleven minutes.

This content analysis study of music videos answered questions concerning the amount and severity of violence content during different time periods of the day. A system of classifying violence content as nonviolent, mostly light, neither light nor serious, mostly serious, and extremely serious was used to evaluate music videos from MTV. One hour from each day was randomly selected for evaluation for a period of thirty days. During this time, there were 313 occurrences of music videos which were aired and subsequently evaluated. The results indicated the majority of these music videos contained mostly light or no violence content. This study also revealed that the most likely time of day a viewer would see videos with violence would be from midnight until eight in the morning.

The problem undertaken in this study was an attempt to discover the image Texas Baptists have of their eight colleges and universities, and to recommend steps to ensure a positive image. The two methods used to determine the image was a questionnaire distributed through a weekly newsmagazine, the Baptist Standard, and telephone interviews. From the study it was concluded that Texas Baptists have a positive image of their eight colleges and universities and rely on the Baptist Standard for their information. The major strength of the eight colleges and universities is the spiritual emphasis, and the major weakness is the high cost of attending a private college or university.
