Relationships Between Brain Biogenic Amines and Reproductive and Defense Behavior in Honey Bees (Apis Mellifera L.).

This dissertation represents an attempt to relate behavioral states of worker honey bees to brain levels of biogenic amines. The first chapter describes the results of experiments which indicated that brain levels of octopamine, dopamine and serotonin were affected by factors including the degree of handling stress, worker age, season of sampling and the source colony from which the workers were sampled. These results helped shape the methods employed in the subsequent chapters. The second and third chapters relate changes in brain dopamine levels to worker honey bee ovarian development. In particular, chapter II showed that an increase in brain dopamine content could be associated with increased ovariole width in worker bees. Chapter III presents experiments which show that both brain dopamine and worker ovary development are reduced by exposure to CO\sb2. The evidence indicates that dopamine is significantly elevated after the ovaries have begun to develop; therefore, brain dopamine may or may not be directly related to stimulation of reproductive processes in worker bees. The final chapter represents an attempt to modify the buzzing responses of groups of honey bees to the alarm pheromone component, isopentyl acetate (IPA). A laboratory bioassay that measured sound responses by groups of bees after exposure to IPA was used to test the effects various doses of ingested amine precursors (tryptophan, 5-hydroxytryptophan and L-DOPA). Ingested 5-hydroxytryptophan was found to reduce responses to IPA, and ingested tryptophan was found to cause hyperactivity in bees. These results are discussed relative to changes in brain chemistry related to ingestion of the different amine precursors

The Acts of the Apostles in the Old Georgian Version

111e Old Georgian version of the Bible is one of many important pieces of the puzzle which textual critics use in their study of the ancient text of scripture. However, its precise role in studying the ancient text remains to be defined, since some critical questions about the nature of the version remain unanswered. Most pressing is the question of the version\u27s translation base, whether Greek, Armenian, or Syriac. Related questions involve the Georgian version\u27s proper place in the history of the New Testament textual tradition. Scholars have yet to reach a consensus regarding the development of that history and its significance for the recovery of the most ancient text of the New Testament. Research on the Old Georgian text of the New Testament will inform the general inquiry by providing a clearer picture of one component of the larger framework. The Old Georgian version has special value since it reflects the biblical tradition of an Eastern church which remained faithful to the Greco-Byzantine world, in sharp distinction to its other Eastern neighbors

A partial test of the contingency model on adult-led groups of children

The problem was to test the applicability of Fiedler\u27s contingency model on 15 adult-led groups of children in a field situation. The effectiveness of high and low least preferred co-worker (LPC) leaders on structured and unstructured group tasks was investigated when leader­ member relations were good and leaders had strong power. The data were analyzed in a 2 x 2 factorial design using the analysis of variance. None of the F tests reached statistical significance, thus the model was not supported. Several possible reasons for the findings were given as well as suggestions for future research

Prescribing the Profession: Representations of Medical Professionalization Debates in American Literary Forms, 1830-1940

This dissertation traces the debates concerning the professionalization of medicine in America across the 19th- and well into the 20th-century and explores how the debates concerning professionalization in any given moment affected popular literary forms. Using Fredric Jameson’s The Political Unconscious as its theoretical framework, this dissertation’s chapters on the gothic, realism, naturalism, and satire trace each mode’s dominant hegemonic position on this issue while showcasing dissenting voices across this century-long discourse. This project’s methodology is centered in the New Historicism. Unlike other projects before it, this dissertation focuses primarily on the historical problem of state laws either regulating or deregulating the professionalization of medicine; however, it also emphasizes close attention to literary form as it traces the dominant and dissenting voices of these popular literary modes. Authors surveyed across this project include Nathaniel Hawthorne, Edgar Allan Poe, H.P. Lovecraft, William Dean Howells, Elizabeth Stuart Phelps, Sarah Jewett, Annie Meyer, S. Weir Mitchell, Charlotte Perkins Gilman, Frank Norris, John Steinbeck, and Sinclair Lewis

An investigation of the relationship between processing rate and memory span in learning disabled children

Slow rate of information processing has been offered as an explanation for the short-term memory problems of learning and/or reading disabled children (e.g., Spring & Capps, 1974). The present investigation used an item identification task and a memory span task to determine whether, when learning and/or reading disabled and non-disabled children are equated with regard to the speed with which they process information, their measured memory spans are also equal. It was hypothesized that the observed memory span differences would be eliminated by equating the two groups on a measure of processing rate

The Characteristics of Successful and Effective Teachers of the Gifted

The purpose of this study was to determine the defining qualities of teachers of the gifted. Five teachers of gifted students in the Knox County System were identified as being successful and effective based on supervisor and administrator evaluation. A series of structured interviews and observations were conducted. A rubric was also completed by the TAG supervisor. The researcher completed a thick description of each TAG teacher’s classroom. Based on the analysis of interviews, observations, and rubric data, the researcher attempted to identify and describe the characteristics, which contributed to the effectiveness of those teachers. The researcher concluded from the data that successful teachers of the gifted seemed to be more flexible or adaptable than their less successful counterparts, had a rich variety of experience, had broad and varying interests, were open and approachable, demonstrated a variety of teaching styles, and considered themselves knowledgeable or interested in research pertaining to gifted education. Neither age nor gender appeared to be a factor
