Frequency Of Rickettsia Sps. In Dermacentor Variabilis And Amblyomma Americanum In Central Hanover County, Virginia, Peggy Ann Keefe

Master's Theses

In the eastern United States, Dermacentor variabilis is the primary vector of Rickettsia rickettsii, the etiological agent for Rocky Mountain Spotted Fever. Cases of Rocky Mountain Spotted Fever in eastern United States increased steadily from 1959 to 1979 to a peak of one case per 200,000 people in 1979 (Morbidity and Mortality Weekly Report, 1985). In 1976, 98.9% of the reported cases of Rocky Mountain Spotted Fever were east of the 100th meridian with 1.1% occurring west of the 100th meridian (Burgdorfer, 1977). Hanover County, Virginia is an endemic area for this disease (Sonenshine, 1971); the last reported case was …

Facial And Pictorial Recognition As A Function Of Massed Versus Distributed Presentation And Imaging Instructions, John Allyn Cayard

Master's Theses

Beneficial effects of distributed practice and rehearsal on recognition has been demonstrated in numerous memory studies for verbal stimuli and manual skills. However, no research has been reported using non-verbal, pictorial stimuli. In addition, few studies have examined the effects of pictorial rehearsal. The present research examines the effects of massed versus distributed practice and post-exposure imaging on pictorial memory. The first and third experiments used faces while the second used plant stimuli. In general, the results showed beneficial effects for post-presentation imaging. Presentation mode produced complex effects, but generally supported the superiority of distributed presentation. The results of Experiment …

Myers-Briggs Type Indicator : Consistency As A Result Of Genuine And Discrepant Personality Type Feedback, Stephanie Ann Falk

Master's Theses

Because of the use of the Myers-Briggs Type Indicator (MBTI; Myers & McCaulley, 1988), psychological practitioners, consultants and researchers need to address implications of personality type feedbeck for clients, employees, and research subjects. This study investigated consistency of the MBTI as a result of genuine and discrepant personality type feedback. True and false feedback was expected to influence subjects in the directton of feedback given. Subjects were selected based on their Sensing-Intuitive (S-N) preference scores. Each of the forty subjects was given either true personality type feedback (TFG) or false personality type feedback (FFG), and then retested. Results showed that …

Half A Memory : The Vietnam War In The American Mind, 1975-1985, Mark W. Jackley

Master's Theses

This study attempts to show how Americans in general remembered the Vietnam War from 1975 to 1985, the decade after it ended. A kind of social history, the study concentrates on the war as remembered in the popular realm, examining novels as well as nonfiction, poetry, plays, movies, articles in political journals, songs, memorials, public opinion polls and more. Most everything but academic history is discussed. The study notes how the war's political history was not much remembered; the warrior, not the war, became the focus of national memory. The study argues that personal memory predominated over political memory for …

Psychosocial Effects Of Juvenile Rheumatic Disease : The Family And Peer Systems As A Context For Coping, Jennifer Ann Harris

Master's Theses

The psychosocial effects of juvenile rheumatic diseases and disease activity were examined among 24 families (12 with a rheumatic disease child, 12 with no chronic illness). Rheumatic disease children were paired with a healthy control child nominated by their classroom teacher. Family and child functioning was assessed through measures of stress, competence, coping, and adjustment while observations in the classroom were made to assess peer relations. MANOVA's and ANOVA's were performed to determine significant differences. Families with a child with inactive rheumatic disease tended to be less likely to seek out and accept help, more likely to put activities into …

Pebble Nest Microhabitats Of Semotilus Species (Pisces: Cyprinidae), James Timothy Magee

Master's Theses

The pebble nest microhabitats of four species of Semotilus were compared. Pit/mound nests of Semotilus corporalis were significantly larger than the pit/ridge nests of Semotilus atromaculatus, Semotilus lumbee, and Semotilus thoreauianus. Nests of S. corporalis were in wider and deeper streams. Pits of S. lumbee nests were longest of the four species; those of S. corporalis were widest and deepest. Semotilus corporalis used a greater proportion of larger stones (23 mm or greater) in nest construction than the other three species. There was no significant difference in the electivity index (percentage of nest pebble sizes versus those of the substrate) …

Training Potential Witnesses To Produce Higher Quality Face Composites, David Bradley Marwitz

Master's Theses

This study attempted to determine if training and familiarization with a composite construction system would improve the quality of subjects' composite production. Subjects were trained in the use of the Mac-a-Mug Pro system over two sessions. During the course of the two meetings, subjects constructed eleven composites (six from memory and five with the face in-view) and were allowed time to practice with the system. Results suggests that the quality of subjects' composites improved with practice. However, training with the composite system prior to exposure to the first face did not lead to higher quality composites. These results have implications …

Risk Perception And Precautionary Intent For Common Consumer Products, Elaine G. Martin

Master's Theses

This study attempted to determine if accident scenario analysis reduces accident frequency misestimations and leads to heightened precautionary intent for products. Subjects generated or were provided with scenarios and made estimates. Other subjects made estimates at varying paces without analysis. These and an additional group then rated their precautionary intent for the products. Subjects also gave rating's for confidence in their estimations reported injury experience related to the products. No differences were found among the group correlations. Analyses showed that the Scenario groups performed no better and sometimes worse than the other groups. The Hurried subjects reported lower precautionary intent …

Regulatory Cell Biology Of Growth Hormone And Prolactin In The Cow Mammary Gland, David Andrew Walkup

Master's Theses

Prolactin (PRL) acts directly on milk secretory cell nuclei to stimulate lactation in rats. In the cow, PRL has been detected in Golgi apparatus, endoplasmic reticulum, and secretory vesicle subcellular fractions of mammary gland , but not nuclear fractions. However, growth hormone {GH) is the galactopoeitic hormone in cows, not PRL. The possibility of GH acting directly on the cow milk secretory cells, and PRL acting on their nuclei was investigated using an immunocytochemical method. PRL and GH were detected in endoplasmic reticular and Golgi apparatus regions of the milk secretory cells, as well as, on nuclear and fat globule …

Medical Care Facility Planning And Regulation In Virginia Through Certificate Of Public Need, Ronald Stephen Webb

Master's Theses

It is the central argument of this thesis that the cost of medical care has been the most salient political consideration in the evolution of certificate of public need Virginia. Certificate of need is a regulatory mechanism that public officials use to achieve health planning goals by controlling medical facility capital expenditures. This thesis sets the development and implementation of certificate of need in Virginia against the broad background of medical facility public policy in this country, as well as significant political movements in Virginia.

Several themes are evident from this analysis. Over time, the center of medical facility planning …

Physical Self Efficacy, Injury, History And Locus Of Control As Predictors Of Athletes' Expected Recovery Actions In Response To Various Levels Of Injury Severity, Kristen R. Goldbach

Master's Theses

Athletes and coaches from a university athletic program at the highest level of competition in the National Collegiate Athletic Association and a college athletic program at the lowest level of competition participated in this project designed to study athletes expected recovery actions when presented with various levels of injury. Physical self-efficacy, locus of control and injury history were considered as mediators in the expected recovery processes including expected recovery time, the number of recovery strategies, and reaction to permission for competition after injury. The Physical Self-Efficacy Scale (Ryckman, Robbins, Thorton, & Cantrell, 1982) and the Nowicki-Strickland Locus of Control Scale …

Shakespeare And Astrology, William Bruce Smith

Master's Theses

The popular ity of astrology in Elizabethan England is ref lected by the large number of references to it in the works of William Shakespeare. The majority of astrological references in the Shakespearean canon are "commonplaces" and do not add signif icantly to our understanding of his work, although they are of interest in studying exactly how much astrological knowledge he possessed. There are astrological references in the plays, however, that are of significance in the study of character in Shakespeare. In certain plays (Romeo and Juliet, The Winter' s Tale) a judgement concerning various individuals ' inner nobility may …

Semantic And Self-Referent Encoding Techniques And Recall Of Meanings Of Unfamiliar Adjectives, Maria K. Whittington

Master's Theses

In order to test the efficacy of levels of processing on memory, recall of unfamiliar adjectives among five encoding groups: a) semantic, b) self-reference specific, c) self-reference general, d) semantic (plural), and e) self-reference specific (plural) was examined. Introductory psychology students at the University of Richmond viewed twenty unfamiliar adjectives and definitions for forty-five seconds each, followed by a five minute distractor task and a seven minute test for recall of the definitions. A second seven minute recall test was administered one week later. There were no significant differences in recall between groups, but a significant effect of time upon …
