Reporting suspected child abuse: a pilot comparison of middle and high school counselors and principals

A survey on experiences with child abuse reporting was obtained from 116 middle and high school counselors and principals across the U.S. Results revealed that counselors throughout their careers had made more reports than principals and perceived themselves to be better trained on child abuse. Those school professionals with fewer years of experience reported more adequate pre-service training. Counselors also failed to report in more instances than principals, citing as deterrents the lack of physical evidence and little faith in child protective services. Most counselors and principals took appropriate action when presented with case examples of child sexual abuse. Recommendations for future research are provided.     

Methods for Quantitative Risk Assessment Using Occupational Studies

Although carcinogenic risk assessment is frequently based on animal bioassay data, occupational studies are generally considered the best source of data for quantitative risk estimation. The model selected for use with occupational study data is required to extrapolate on age, exposure level, and temporal exposure pattern. Relative and absolute risk models are examined, as are alternatives for the definition of a dose (exposure) variable. The models express disease incidence as a function of the chosen exposure variable and convert incidence into estimates of lifetime risk. In this form, predictions of the models can be compared. The methods are illustrated using three examples: arsenic exposure and respiratory cancer, leukemia associated with benzene exposure, and asbestos-induced mesothelioma.     

爱德华·汤普森的伦理激进主义及其遗产

汤普森思想的本质是一种伦理激进主义,他不仅受到马克思主义的影响,也受到英国本土许多社会主义和非社会主义思想传统的影响。尽管其理论存在某些模糊性,汤普森对政治生活的积极参与,及其对民主辩论的倡导都是弥足珍贵的财富,而其思想遗产的消散既是巨大的理论损失,也是巨大的政治损失。
