Collaboration: Faculty Perspective, William D. Woody Jan 2008

Collaboration: Faculty Perspective, William D. Woody

SPS Faculty Publications

From the chapter introduction: Over the past decade and a half, I have worked with many undergraduates as teaching assistants, research assistants on my projects, and advisees who conduct research for honors or other advanced programs. However, in very few cases have I had the special opportunity to genuinely collaborate with a student on research. The materials that follow define collaboration and set it apart from other modes of working with undergraduates, discuss selection processes, goals, challenges, and advantages of collaboration, and provide examples from my work with an outstanding undergraduate student, Joseph Hamm. I conclude this chapter with specific …

Systems Biology Meets Stress Ecology: Linking Molecular And Organismal Stress Responses In Daphnia Magna, L-H Heckmann, Rm Sibly, R Connon, Hl Hooper, Et Al Jan 2008

Systems Biology Meets Stress Ecology: Linking Molecular And Organismal Stress Responses In Daphnia Magna, L-H Heckmann, Rm Sibly, R Connon, Hl Hooper, Et Al

School of Biomedical Sciences

BACKGROUND: Ibuprofen and other nonsteroidal anti-inflammatory drugs have been designed to interrupt eicosanoid metabolism in mammals, but little is known of how they affect nontarget organisms. Here we report a systems biology study that simultaneously describes the transcriptomic and phenotypic stress responses of the model crustacean Daphnia magna after exposure to ibuprofen. RESULTS: Our findings reveal intriguing similarities in the mode of action of ibuprofen between vertebrates and invertebrates, and they suggest that ibuprofen has a targeted impact on reproduction at the molecular, organismal, and population level in daphnids. Microarray expression and temporal real-time quantitative PCR profiles of key genes …

Perceived Barriers To Organizational Creativity: A Cross-Cultural Study Of British And Egyptian Future Marketing Managers, Aa El-Masry, M Mostafa Jan 2008

Perceived Barriers To Organizational Creativity: A Cross-Cultural Study Of British And Egyptian Future Marketing Managers, Aa El-Masry, M Mostafa

Plymouth Business School

Purpose – The overall purpose of this research is to further the understanding of how future marketing managers in Egypt and the UK perceive creativity barriers. The paper also examines the construct validity of the barriers to creativity scale in an Arab non-Western context. Design/methodology/approach – A sample of 125 respondents was used to achieve the research purpose. Respondents completed a 17-item instrument designed to assess barriers to creativity in business organizations. Findings – Discriminant analysis results showed that Egyptians differ from British with respect to their attitudes towards organizational creativity barriers. t-test procedure confirmed also that gender and age …

We present direct upper limits on gravitational wave emission from the Crab pulsar using data from the first 9 months of the fifth science run of the Laser Interferometer Gravitational-wave Observatory (LIGO). These limits are based on two searches. In the first we assume that the gravitational wave emission follows the observed radio timing, giving an upper limit on gravitational wave emission that beats indirect limits inferred from the spin-down and braking index of the pulsar and the energetics of the nebula. In the second we allow for a small mismatch between the gravitational and radio signal frequencies and interpret …
