The article presents guidelines for college teachers to teach organic chemistry in the U.S. These guidelines include inquiring about the internal support available for teachers at an institution, regular performance assessments of full-time, tenure-track teachers, and writing a proposal for research support. It provides information on the traditional curriculums for chemistry courses, student recruitment and mentoring, and professional ethics.

The article discusses the medieval Inquisition and the significance of the lack of Catholic voices of opposition that have been recorded in literature from that time. The author states that Catholics at this time are understood to have allowed the continuation of the Inquisition as long as those being prosecuted were clearly heretics.

Research suggests that restricted and repetitive behaviors (RRBs) can be subdivided into repetitive sensory motor (RSM) and insistence on sameness (IS) behaviors. However, because the majority of previous studies have used the autism diagnostic interview-revised (ADI-R), it is not clear whether these subcategories reflect the actual organization of RRBs in ASD. Using data from the Simons simplex collection (n = 1,825), we examined the association between scores on the ADI-R and the repetitive behavior scale-revised. Analyses supported the construct validity of RSM and IS subcategories. As in previous studies, IS behaviors showed no relationship with IQ. These findings support the continued use of RRB subcategories, particularly IS behaviors, as a means of creating more behaviorally homogeneous subgroups of children with ASD.
