This paper provides results of a descriptive analysis of peer-reviewed, single subject design, intervention research on augmentative and alternative communication (AAC) for individuals with severe disabilities, from birth to 21 years, published in English between 1997 and 2003. A database of 40 studies was found that met seven specified criteria. The descriptive analysis showed that a variety of antecedent, both adult and child directed, and consequent intervention components, typically used in combination, were effective in improving communication. Most research contexts were rated as less natural. Parents, teachers, and siblings or peers were infrequently involved in intervention. When problem behavior and communication were targeted, functional communication training (FCT) was the method of choice. Treatment integrity was infrequently measured. When measured, generalization and maintenance of treatment effects were good but were reported less than half of the time. Implications for interventionists and researchers are discussed.
Descriptive and qualitative analyses were applied to a database of 111 assessment-based studies published between 1997 and 2002 on the problem behavior of school-age individuals with disabilities, to determine how frequently key components of positive behavior support (PBS) were being used. While most of the database reported reductions in problem behavior, only half focused on and reported increases in replacement skills. Interventions frequently reported were positive reinforcement, antecedent-based approaches, and skill training. Interventions using parent/teacher skill training were infrequent, and self-management, peer-mediated intervention, and comprehensive lifestyle change were rare. Involvement of family and educators was reported in one quarter of the database, with the highest involvement of nonresearchers during assessment. Studies using functional assessment alone or in combination with functional analysis and studies conducted in natural settings were more likely to use key features of PBS than were studies that used only functional analysis or were conducted in atypical settings.
The rapid growth of computer science in both academia and industry creates a special problem with faculty turnover. This paper examines data from a national study of computer science departments to describe the circumstances surrounding faculty turnover in computer science and identify the major factors related to faculty departure. It concludes with suggested approaches for addressing the situation.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
