Copepod Grazing Selection And Particle Discrimination On The Basis Of Psp Toxin Content, Gregory J. Teegarden

Graduate School of Oceanography Faculty Publications

Omnivorous copepods are capable of discriminatory feeding using mechano- and chemosensory mechanisms. The presence of phycotoxins in phytoplankton often results in reduced consumption of such potential prey by copepods, though it has not been clear if this is the result of discriminatory feeding by either tactile (mechanosensory) or chemosensory recognition of toxic prey, or perhaps a physiological response to ingested neurotoxic compounds. In this study, experiments were performed to determine whether 3 species of marine copepods (Acartia tonsa, Centropages hamatus, and Eurytemora herdmani) that commonly co-occur with toxic Alexandrium spp. dinoflagellates were capable of discriminating between cultured Alexandrium spp. strains …

Convective Injection And Photochemical Decay Of Peroxides In The Tropical Upper Troposphere: Methyl Iodide As A Tracer Of Marine Convection, Daniel S. Cohan, Martin G. Schultz, Daniel J. Jacob, Brian G. Heikes, Donald R. Blake

Graduate School of Oceanography Faculty Publications

The convective injection and subsequent fate of the peroxides H₂O₂ and CH₃OOH in the upper troposphere is investigated using aircraft observations from the NASA Pacific Exploratory Mission‐Tropics A (PEM‐Tropics A) over the South Pacific up to 12 km altitude. Fresh convective outflow is identified by high CH₃I concentrations; CH₃I is an excellent tracer of marine convection because of its relatively uniform marine boundary layer concentration, relatively well‐defined atmospheric lifetime against photolysis, and high sensitivity of measurement. We find that mixing ratios of CH₃OOH in convective outflow at 8–12 km …

Maltreating Caregivers: An Application Of The Transtheoretical Model Of Change, Lisa M. Jones

Open Access Dissertations

Many of the decisions that must be made by child protective service (CPS) agencies involve assessing the extent to which maltreating caregivers have made or are ready to make changes in their parenting behaviors. Yet, little is known about the process of change for these caregivers and no method is available to systematically measure their success in making the changes that CPS agencies require of them. The current study applies the Transtheoretical Model of Change to the problem of child abuse and neglect. The Transtheoretical Model has successfully measured change in many health-related behaviors including smoking and excercise. More recently, …

Observed Conflict, Sexual Experience, Pornography, And Coercive Behavior As Predictors Of Men’S Sexual Arousal To Sexual And Violent Images, James Allen Miller

Open Access Dissertations

This study investigated predictors of sexual arousal to erotic, rape, and non-sexual violent videotaped stimuli in a sample of 82 undergraduate men. Questionnaire self-report measures of observed parental conflict, conflict tactics practiced in interpersonal relations, coercive sexual behavior, variety of sexual experiences, and frequency of using various forms of pornography, as well as a number of relevant demographic measures like fraternity affiliation, athletic participation, frequency of intercourse, and number of sexual partners, were assessed. These measures were used in analyses that tested relationships among these variables and determined group differences based on dichotomized classification of high and low scores.

Subsequently, …

A Media Skills Intervention For Adolescents On Gender Attitudes, Beliefs, And Behaviors, Barbara E. Silver

Open Access Dissertations

This study examined the effects of a media literacy intervention on the gender attitudes, beliefs, and behaviors of a sample of 9^th and 11^th grade adolescents. As a time of identity development, adolescence can be especially challenging for girls, as they are faced with traditional cultural expectations about gender. It is proposed that the media, particularly television, reinforce traditional ideas about gender for both sexes, including traditional interactions with other gender peers, and may contribute to low social self-esteem in girls, with negative outcomes. A 7-session media literacy workshop, using a pretest/post-test control group design, was implemented with …

Study Of The Effects Of Ultraviolet Radiation On Tetraselmis Chuii Growth And Morphology, Charles T. Audette

Open Access Master's Theses

Exposure of batch cultures of Tetraselmis chuii to three levels (0.020, 0.126 and 0.217 m W/cm²) of artificial UV-B caused a depression of exponential growth corresponding to UV-B dose. Three UV-B experiments were conducted. Cultures were maintained at 25 °C on a 18L:6D photoperiod for the first two experiments and at 12L: 12D for the last experiment. Growth was measured daily by measuring optical density at a standard wavelength of 750 nm. This was compared periodically with hemacytometer cell counts. Cell morphology (projected cell area, length, width, perimeter, and roundness) was determined by microscopic image analysis, and showed …

The Application Of The Population Approach To Pharmacokinetics In Drug Development, Kimberley Anne Jackson

Open Access Dissertations

The population approach to pharmacokinetic involves the estimation of mean pharmacokinetic parameters and their variability within a study population. Advantages of this approach include the ability to i) utilize sparse data, ii) analyze data from large, heterogeneous populations to obtain realistic and relevant estimates of variability and iii) evaluate the influence of patient characteristics on pharmacokinetic estimation.

Sparse data from a phase ill clinical trial of the protease inhibitor, nelfinavir, were used to obtain estimates of the pharmacokinetic parameters and their variability. The effects of patient covariates on the pharmacokinetic parameters of nelfinavir were evaluated. Clearance, estimated from data in …
