Composite materials are widely used in demanding applications in aerospace and other industries. In order to understand the complex behaviour of the composite materials and their components, standardised test methods are used. One example is the double cantilever beam (DCB) test in which the test specimen is loaded in an opening, i.e., tensile mode. Failures in composite materials loaded compression are different from those in tension, for example, kink band or buckling-like failures can occur. In this project, several DCBs are designed and a new fixture which allows for compression testing of a DCB is developed for an existing Instron testing machine. The fixture overcomes a known problem of tensile peak causing the failure of the adhesive at the inner surfaces of the DBC by applying additional compressive loads along the outer surfaces of the DBC. The compressive forces can induce the desired kink band formation so that researchers can better study the failure mode. The conceptual development of the new DCBs and the new fixture are presented. Several prototypes of the specimens and the fixture are modelled using the three-dimensional (3D) computer-aided design software Creo Parametric 2.0.  One of the fixtures is selected to further study. The different DCB specimens are studied in order to obtain information about the kink band using 3D finite element analysis with the software programme Abaqus CAE. The selected fixture is analysed to determine if there are any areas of concern. Finally, the behaviour of the compression stress along the DCB using two pairs of forces is studied. Unfortunately, it is determined that the tensile peak experienced by the adhesive cannot be eliminated by the application of two pairs of compressive loads, one at the free end and the other in the vicinity of the tensile peak. Several suggestions are made for future work which might serve to reduce the tensile peak; e.g., the movable force couple is applied as a surface load instead of a point load. For this, the fixture will have to be modified with a new geometry, although the DCB could be the same. This will allow further work to focus on the combined behaviour of the tensile peak and the fixture.

In this dissertation I seek to answer the research question of who are those people that have the ability and motivation to facilitate other people’s creative thinking. Actors who are in the creator’s social environment, such as her coworkers and family members, can potentially enhance the creator’s level of creativity. Although these contacts can be active collaborators of the creator’s thinking processes and can eventually have a significant impact on organizational creativity, so far their role in organizational life has been overlooked by researchers. Consequently, in my dissertation I develop a theory of “creativity catalysts”, and define a creativity catalyst as an employee who helps to improve the usefulness and novelty (i.e. creativity) of the ideas and products produced by another employee (i.e. the creator) through direct interpersonal interaction with the creator. I examine two aspects of serving as a catalyst to another’s creativity: the intensity of a creativity catalyst’s contribution and the span of a creativity catalyst’s contribution. Intensity of contribution is conceptualized as the extent to which the creativity catalyst can improve the output generated by the creators to be more novel and useful. Span on the other hand, is the number of people that perceive an individual as a catalyst for her own creative performance. To answer the research question, I develop and empirically test a theory of creativity catalysts by integrating a social capital theory lens (i.e. structural social capital and relational social capital) with a stable motivational orientation (i.e., learning goal orientation). First, I argue that a catalyst’s relational social capital (i.e., quality of relationships with her coworkers) in the organizational communication network determines her motivation to take the role of a creativity catalyst. Second, I argue that the catalyst’s structural social capital (i.e., the extent to which she can connect with the disconnected others in her network structure) underlines her ability to contribute to others’ creativity. Integrating these two arguments, I hypothesize that the catalyst’s relational social capital (i.e., the motivation to become a creativity catalyst) interacts with her structural social capital (i.e., the ability of a creativity catalyst) in predicting both the intensity and span of the catalyst’s contribution to her coworkers’ creativity. Second, I hypothesized that learning goal orientation, a stable motivational orientation, interacts with the situational motivational characteristic of relational social capital in predicting both the span and intensity of a catalyst’s contribution to her coworkers’ creativity. To test my hypotheses, I first ran a pilot study on a sample of full-time MBA students in order to validate the creativity catalyst measure; and then tested my hypothesized model on employees from two companies, using multiple data sources over multiple phases of data collection. Consequently, I found support for both of these interaction hypotheses on the intensity and span of a creativity catalyst’s contribution to her coworkers’ creativity. Theoretical and practical implications of these findings, and future research directions are discussed.

This research study investigated the relationship to the pre-enrollment factors of admissions-to-enrollment and orientation-to-enrollment timespans to transfer student success as measured by persistence and the length of time taken to earn a baccalaureate degree. This quantitative study analyzed secondary data (N = 357) from a large, four-year, public research institution in the southeast United States. A logistic regression analysis was used to explore the relationships between the pre-enrollment timespans and persistence. The relationship between the admissions-to-enrollment timespan and persistence was not statistically significant. The orientation-to-enrollment timespan was found to have a statistically significant relationship to persistence (p < .05). This indicated that students who had increased orientation-to-enrollment timespans were more likely to persist. To further explore this relationship, a multiple logistic regression analysis was conducted to control for possible extraneous demographic, pre-enrollment, and enrollment variables. The relationship of orientation-to-enrollment timespan and persistence continued to be statistically significant. An ordered logistic technique was used to explore the relationship between the admissions- and orientation-to-enrollment timespans and time-to-degree completion. Neither timespan was found to have a significant relationship with time elapsed to complete the degree. Implications for admissions and orientation timespans were discussed in relation to transfer student transitions.

This study introduces narcissistic entitlement as a correlate of homonegative attitudes and behaviors and examines the relative strength of relations along with established correlates of right-wing authoritarianism (RWA), social dominance orientation (SDO), conformity with masculine norms, and intrinsic religious orientation. It also tests the role of negative attitudes towards lesbian women and gay men (ATLG) in mediating the relationship between the predictor variables and gay- and lesbian-rejecting and affirming behaviors. Implications for what these findings may offer psychologists are discussed, as are ways findings may inform the political process. Earlier studies support the link between entitlement and homonegativity (Exline, et al., 2004). Narcissism was positively related to dominance, neuroticism, social anxiety, and more aggressive/sadistic and rebellious/distrustful interpersonal styles (Emmons, 1984). Entitled narcissists are quick to take offense (McCullough, et al., 2003), externalize blame (Campbell, et al., 2000), and derogate or attack those who provide ego-threatening feedback or social rejection (Bushman, et al., 2003; Konrath, et al., 2006). Entitlement increases the risk of the narcissist becoming prone to hostile and reactive aggression and extreme violence, even without an ego-threat (Bushman, et al., 2003; Reidy, et al., 2008). Participants were recruited through the Department of Educational Psychology subject pool and data was collected by online survey. Given the focus on heterosexual men's attitudes toward lesbian women and gay men, participants were excluded from analysis if they identified as female, bisexual, or homosexual. Results indicated that entitlement, RWA, and intrinsic religiosity, but not conformity to masculine norms or SDO, were related uniquely to ATLG. ATLG was also related uniquely with measures of behavior, positively to gay- and lesbian-rejecting behaviors, and negatively with gay- and lesbian-affirming behaviors. ATLG was found to significantly mediate the links of entitlement and RWA with lesbian- and gay-rejecting behaviors. Results also indicated that the indirect link of intrinsic religious orientation with lesbian- and gay-rejecting behaviors was significant. Additionally, ATLG significantly mediated the links of entitlement with lesbian- and gay-affirming behaviors. Such an examination advances research and practice by identifying unique correlates of homonegative attitudes and the mechanisms through which they are related to lesbian- and gay-rejecting and -affirming behaviors. / text
