Process environmental philosophy

Description: A process-information approach is examined as a foundation for an environmental philosophy that is dynamic and elastic, with particular emphasis on value, beauty, integrity and stability supporting Aldo Leopold's vision. I challenge one of the basic assumptions of Western philosophy, namely the metaphysical primacy of substance. The classical, medieval and modern metaphysics of substance is presented with particular attention given the paradoxes of substance. Starting from the philosophy of Her… more

Developmental Patterns of Metabolism and Hematology in the Late Stage Chicken Embryo (Gallus Domesticus) at Two Incubation Temperatures.

Description: How temperature affects physiological development in the chicken embryo is unknown. Embryos incubated at 38°C or 35°C showed no difference in growth or survival. The time to hatching was longer in 35°C than 38°C embryos (23.7 vs. 20.6 days), but unaffected was the relative timing of appearance of developmental landmarks (internal, external pipping). At stage 43-44, 38°C embryos maintained oxygen consumption around 1 mL/g/h despite acute temperature reduction (suggesting thermoregulatory maturat… more

Plays of Tennessee Williams as opera: An analysis of the elements of Williams's dramatic style in Lee Hoiby's Summer and Smoke and André Previn's A Streetcar Named Desire.

Description: There are two major, well-known operas based on plays of Tennessee Williams. He refused many times throughout his life to give permission for his play, A Streetcar Named Desire, to be set as an opera. It was not until the 1960s that he granted permission for Lee Hoiby to choose any of his plays as a basis for a new opera. Hoiby chose Summer and Smoke, a play which was written at approximately the same time as Streetcar. Lanford Wilson created the libretto for the opera which was given its pre… more

Influence of Cholesterol Import on Aspergillus fumigatus Growth and Antifungal Suscepibility

Description: Invasive pulmonary aspergillosis is a life-threatening fungal infection commonly observed in immunocompromised patients and has a mortality rate approaching 100% once the disease is disseminated. Aspergillus fumigatus is the most common pathogen. Early diagnosis improves the prognosis but is very difficult since most signs and symptoms are nonspecific. Antifungal therapy, usually based on sterol biosynthesis inhibitors, is also of limited efficacy. In my attempts to discover a diagnostic st… more

Mechanical behavior and performance of injection molded semi-crystalline polymers.

Description: I have used computer simulations to investigate the behavior of polymeric materials at the molecular level. The simulations were performed using the molecular dynamics method with Lennard-Jones potentials defining the interactions between particles in the system. Significant effort was put into the creation of realistic materials on the computer. For this purpose, an algorithm was developed based on the step-wise polymerization process. The resulting computer-generated materials (CGMs) exhibit… more

Register Unification in Light of Twentieth-Century Vocal Pedagogy

Description: The registers of the singing voice, as commonly understood by singers, refer to the different vocal qualities induced by adjustments at the level of the larynx and of the vocal tract. This explains why register unification can be approached either one or a combination of the following procedures: (1) resonance alignment through vowel modification, (2) register alignment through intensity exercises. The wide-spread acceptance of vowel modification has made singers reluctant in exploring other av… more

Client's Perception of Seeking Counseling as a Function of Counselor Ethnicity, Counselor Acculturation, Counselor Gender, and Client Gender

Description: Due to demographic shifts and efforts to recruit culturally diverse professionals, it is plausible that more Caucasians will encounter ethnic minority counselors in the future. Yet, the majority of multicultural literature has only emphasized Caucasian counselors' multicultural counseling competence. Research has rarely discussed how ethic minority counselors influence the perceptions of Caucasian clients. The research purpose was to explore how acculturation and gender of Asian and Caucasian c… more
