Diamond Thin Film Sensors For Hypersonic Flow Studies, Bhaskar Kumar Bulusu

Electrical & Computer Engineering Theses & Dissertations

Conventional metal film sensors can measure flow instabilities of the order of 60 kHz. The turbulence fluctuations in the hypersonic regime are of the order of 200- 400 kHz. To measure these fluctuations, sensors with an enhanced frequency response are required. Therefore, it is required to identify the parameters to enhance the frequency response. These include parameters such as the temperature sensitivity, the resistivity, the thermal conductivity, the diffusivity, specific heat capacity and the geometric size and shape of the film and the substrate. A selection of materials was then carried out to maximize the frequency response. Diamond was identified …

Body-Image Disturbances In Anorexia Nervosa And Bulimia Nervosa: A Meta-Analysis Of Extant Research, Edwin A. Deagle Iii

Psychology Theses & Dissertations

Body-image disturbances are key among the diagnostic criteria for anorexia nervosa and bulimia nervosa. However, the specific nature of this disturbance is not precisely defined by DSN-III-R or DSN-IV. The numerous body-image assessment techniques have generated inconsistent and conflicting results concerning the nature of body image in the eating disorders. This study is the first quantitative review, a meta-analysis of (n = 59) studies of body image among anorexics and bulimics relative to controls. The results indicated that attitudinal measures of body dissatisfaction, including perceptual self-ideal discrepancy measures, produce much larger effect sizes for clinical populations than do perceptual assessments …

Vigilance: Instruction Effects And Personality Correlates Of Performance Workload And Boredom, David A. Sawin

Psychology Theses & Dissertations

The present laboratory study examined variables that are believed to impact vigilance in operational settings. Instructions were manipulated by telling half of the subjects to relax, and to focus on positive task characteristics (relaxation-emphasis), while the remaining subjects were instructed to "detect as many critical signals as possible" (detection-emphasis). It was expected that instructions emphasizing detection would lead to increased subjective workload ratings, though all subjects participated in the same 30-min vigilance task. Further, it was expected that decreasing demands by emphasizing relaxing qualities of the task would not impact performance, though lower workload ratings were expected. In addition, response …

The Effects Of Perceived Upward Influence Rewards And Personality Moderators On Job Satisfaction And Productivity In An Employee Suggestion Program, David J. Braun

Psychology Theses & Dissertations

The extent to which work satisfaction, task satisfaction, suggestion quantity and suggestion quality may be affected by upward influence and reward in a suggestion program was investigated using 160 students as subjects. Locus of control and growth need strength were investigated in terms of their effects as personality moderators. Subjects offered suggestions during three trials for nine topics representing university problems. The percentage of suggestions accepted by a review committee was manipulated as four levels of an upward influence condition (0'/o, 25'/0, 50'/o and 75'/o). In addition, subjects were randomly assigned to either a no-reward or reward condition, in which …

Judging Statistical Significance: The Effects Of Standard Error Bar Formats And Visual Displays, Rebecca Wilson Miller

Psychology Theses & Dissertations

The present study examined various graphical displays for illustrating statistical significance. These displays were created following Dunlap and May's (1989) recommendation about representing statistical significance in figures with error bars derived from the pooled estimate of error variance. In the first experiment, 15 graduate students were asked to judge whether the relationships depicted in a series of graphs and tables were significant or nonsignificant. Four significance levels were combined factorially with three standard error bar formats, unidirectional opposite direction, unidirectional same direction, and bidirectional, and two displays, line graphs and bar graphs. A tabular display was also presented for comparison. …

Premature Infant Attractiveness And Temperament In The Prediction Of Maternal Sensitivity, Cheryl L. Shiflett

Psychology Theses & Dissertations

The influence of infant attractiveness and temperament on maternal sensitivity is important to examine in infants born prematurely because many characteristics associated with prematurity, such as postnatal cranial molding, may negatively impact maternal response. The present study investigated maternal perceptions of preterm infant development, attractiveness, age, and temperament, and examined the influence of attractiveness and temperament on maternal sensitivity. Twenty-nine mothers of preterms completed questionnaires on infant behavior, development, temperament, rated photographs for attractiveness and age, and were videotaped with their infant to measure maternal sensitivity according to CARE-Index procedures (Crittenden, 1988). Results indicated that mothers have more negative expectancies …

Mature Librarians And The University Faculty: Factors Contributing To Librarian's Acceptance As Colleagues, Jean A. Major

Libraries Faculty & Staff Publications

In an exploratory study, eighteen mature librarians who are considered colleagues of teaching faculty were interviewed to understand actual instances of acceptance within an institution. Participants demonstrated that performing the role of librarian and exploiting campus governance activities contributed significantly to collegial acceptance and were used to advantage more often than a common interest in research. The most important factor, however, was self-confidence as a librarian. Models and mentors reportedly helped subjects learn to be colleagues with other faculty; library school often did not.

Responses To Dissatisfaction In Psychotheraphy: The Influence Of Prior Satisfaction, Perceptions Of Problem Severity And Attachment Style, Christopher C. Read

Psychology Theses & Dissertations

This study examined the influence of prior satisfaction, perceptions of problem severity, and attachment style in determining Rusbult's Exit, Voice, Loyalty, and Neglect responses to dissatisfying events depicted in a psychotherapy simulation. Constructive responses to therapy dissatisfaction (i.e., Voice and Loyalty) were positively related to prior satisfaction with the therapist and negatively related to perceptions of problem severity. Destructive responses (i.e., Exit and Neglect) were negatively related to prior satisfaction and positively related to problem severity. Attachment style was associated with individual differences in approaches to resolving conflict, but it was not consistently related to Exit, Voice, Loyalty, and Neglect …

American Christianity And Its Role In The Denigration Of The African-American Identity As Found In African-American Literature, Zelda Lockhart

English Theses & Dissertations

The positive effects of American Christianity on the African-American from slavery to present day are often analyzed in African-American literature, which depicts black characters who are grateful to God, mostly for giving them the strength to endure the many social and psychological abuses inflicted by American institutions. African-American literature, however, also depicts characters whose relationship with Christianity subordinates them in American society.

The following chapters will explore the downfalls and ironies of an African-American/Christian dichotomy, and show how the historical events of America have influenced African-American Christianity.

Chapter One gives a historical account of America's involvement in the Transatlantic slave …

Maternal Perceptions Of The Social Development And Behavior Of Asthmatic Children, Chelley A. Merrell

Psychology Theses & Dissertations

To assess the effects of asthma on the social development and behavior of asthmatic children, 60 mothers of 6- to 13-year-old children (30 mothers of asthmatics, 30 mothers of non-asthmatics) completed the Child Behavior Checklist (CBCL: Achenbach & Edelbrock, 1986) and were administered the Vineland Adaptive Behavior Scale (Vineland: Sparrow, Balla, & Cicchetti, 1984). It was hypothesized that asthmatic children would lag behind non-asthmatic peers in social development, defined as the development of age-appropriate behaviors (i.e., communication, daily living skills, and socialization). In addition, it was hypothesized that asthmatic children would exhibit more internalizing behaviors than non-asthmatic children. There were …
