Parallel-Vector Design Sensitivity Analysis In Structural Dynamics, Yongxing Zhang

Civil & Environmental Engineering Theses & Dissertations

In this study, the design sensitivity analysis is for the purpose of providing constraint derivative information for structural optimization under dynamic loads. Various existing formulations are reviewed, and the direct differentiation method is justified as the best one for design sensitivity analysis in structural dynamics. An alternative formulation for design sensitivity analysis with direct differentiation method is developed. The alternative formulation works efficiently with the reduced system of dynamic equations, and it eliminates the need for expensive and complicated eigenvector derivatives, which is required in the existing reduced system formulation. The relationship of the alternative formulation and the existing reduced …

Creativity Its Phenomenology In Man And Nature, Margaret L. Mccoy

Institute for the Humanities Theses

The phenomenal world comes into being. The act is an autonomous process weaving the abstract world and the concrete world into one reality. We name this process "Creativity." A journey into mind and matter, into the inner subjective realm and the outer objective realm, is required to observe Creativity's grand performance. Western thought may be revolutionized in finding that in exploring Creativity man is exploring himself; Nature has consciousness as he does, and barriers between mind and matter are non-existent in the womb of creation. As ancient philosophies and mystical ideas of the East once proposed: the Many is One. …

An Analysis Of Urban Higher Education Ceo's Perceptions Of Critical Leadership Behaviors, Linda Ferguson Banis

Theses and Dissertations in Urban Services - Urban Education

The research question for this study asked if CEO's (Chief Executive Officers) of urban higher education institutions hold the same values and beliefs as those attributed to business and industry CEO's through the business literature. Through survey methodology, the analysis of urban higher education CEO's perceptions of critical leadership behaviors revealed very similar belief patterns. The primary discrepancies between the research group and their industry counterparts lie in the degree to which critical behaviors are espoused and in the acceptance of transformational leadership as a proactive model for effective organizational change. The responses to the open-ended portion of the questionnaire …

The Parties Quarrae, Michael E. Malone

Institute for the Humanities Theses

During Thomas Jefferson's educational days in Williamsburg, Virginia, he was fortunate to have the association with three learned men, William Small, George Wythe, and Lt. Governor Francis Fauquier. The men met often at the governor's palace during the years 1760-64. Jefferson referred to their association as the "parties quarrae."

Most historians agree that the time spent with Small, Wythe, and Fauquier had profound influence on the establishment of Jefferson's "enlightenment" philosophy. Little, however, is known about the details of the regular meetings in the palace.

The focus of this creative project is the fictional discovery of Jefferson's "lost" Autobiography, finished …

Also, Likert-type scales reflected perceived comfort, perceived marriage satisfaction, and divorce probability for a husband and wife represented in an egalitarian and a traditional sex-segregated scenario. Sex-role attitude scores were examined by categorizing students according to gender and high/low intrinsic and extrinsic groups. …

The Effects Of Confidentiality Gender And Subject Shyness On The Social Desirability Response Bias, Scott D. Bradshaw

Psychology Theses & Dissertations

This study examined the effect of confidentiality on objective and semi-projective personality measures. Confidentiality was manipulated by telling the subject his/her responses would, or would not, be discussed with the examiner. The effect was assessed by comparing a subject s scores on two different measures of the same construct'ne test completed with confidentiality, the other without. It was hypothesized that subjects in the non-confidential condition would alter the responses on the measures and that this effect would be greatest with opposite gender pairings of subjects and examiners. The possible moderator variables of shyness, self-monitoring, and self-actualization were also examined. Data …

The Effects Of Social Support On The Psychological Adjustment Of Navy Wives Experiencing Deployment, Marci A. Harris

Psychology Theses & Dissertations

The military, particularly a Navy deployment, provides unique challenges and stresses to the military family. The present study investigated the effects of social support on the psychological well-being of Navy wives experiencing spousal deployment. Sixty-three Navy wives in the Tidewater, Virginia area completed questionnaires on depression, self-esteem, and daily stress, as well as on the size of and satisfaction with affective and instrumental support. Assessments were made before, during, and after the deployment. Results of stepwise regressions showed that satisfaction with various aspects of social support significantly (p < .05) predicted levels of depression, self-esteem, and daily stress at all three phases of deployment. Results also showed that psychological wellbeing was lowest at middeployment. Findings demonstrate the importance of developing satisfactory social support systems prior to, during, and after deployment.

Effects Of Extraversion And Gender On Self-Disclosure Of Emotion With A Same-Sex Friend, Patrick M. Ulmen

Psychology Theses & Dissertations

The study examined subjects' perceptions about disclosure of emotion by a stimulus person who was depicted as extraverted or introverted, and subjects' self-disclosure of emotion based on their own level of extraversion. In addition, the role of gender in disclosure of emotion was examined. The findings on differences in disclosure of emotion based on gender are considered tentative. Males self-disclosed anger more to same-sex stimulus persons than did females, but this was the only significant difference. An introverted compared to an extraverted stimulus person was found to elicit more disclosure about emotions associated with calmness and depression. Emotions which an …

The Role Of Priming In The Rating Process: An Investigation Of Priming Effects In A Simulated Assessment Center, Rebecca Regan Keever

Psychology Theses & Dissertations

Through interactions with others in the assessment center, an assessor may be exposed to potentially biasing information (priming). Research from other fields indicates that raters will use this prior information in making judgments. This study examined priming in a simulated assessment center, using a 2 (primed or unprimed) by 2 (trained or untrained) by 2 (prestige-relevant or relevant-only source of information) within-subjects design. A total of 136 participants observed and rated the behavior of three candidates. Primes describing behaviors engaged in by each candidate were presented before participants observed them. All information was presented by either a professor or a …
