With the multitude of new chemicals being synthesized and the paucity of long-term test data on chemicals that could be introduced into the environment, innovative approaches must be developed to determine the health and environmental effects of chemicals. Research was conducted to employ quantitative structure-activity relationship (QSAR) techniques to(More)
The toxicity data of pesticides were summarized and compared amongst different animal species and types of bioassays. These comparisons showed the expected inter-species and inter-bioassay variability. After quantitative and statistical analysis of these data, it was concluded that, on the average, a 2-year dog bioassay detected toxic responses at similar(More)
Behavioral health providers are increasingly called upon to develop outcomes strategies that highlight opportunities for performance improvement and assess in turn the impact of applying total quality management (TQM) principles to treatment outcomes. This article describes the evolution of an outcomes assessment program at a private psychiatric facility,(More)
Quantitative estimates of cancer risk generally involve low-dose extrapolation based on an exponential dose-response model for dichotomous response data. Frequently more than one data set is available. If a careful analysis of the biological issues indicates that more than one of the available data sets could be used in the quantitative estimate of cancer(More)
There are often several data sets that may be used in developing a quantitative risk estimate for a carcinogen. These estimates are usually based, however, on the dose-response data for tumor incidences from a single sex/strain/species of animal. When appropriate, the use of more data should result in a higher level of confidence in the risk estimate. The(More)
Hybrid learning is a combination of on-line learning and face-to-face sessions. This research sought to answer the question of "Can Hybrid Learning be Utilized To Teach Working Sonographers to perform breast Elastography?" We designed a hybrid course entitled "Breast Elastography for Working Sonographers." This course consisted of four on-line training(More)
