Prenatal cocaine exposure: a comparison of 2-year-old children in parental and nonparental care

Effects of prenatal cocaine exposure and parental versus nonparental care on outcome at 2 years of age were examined. The sample included 83 cocaine-exposed and 63 nonexposed children and their caregivers; 49 and 34 of the cocaine-exposed children experienced parental and nonparental care, respectively. Prenatal drug exposure was not related directly to children's outcome at 2 years of age. However, compared with cocaine-exposed children in parental care, those in nonparental care experienced a more optimal environment and performed better in several developmental domains at 2 years of age in spite of being at greater neonatal risk. Further analyses suggested that this protective effect of nonparental care was in part due to nonkin rather than kin care.     

Semantic networking: The new kid on the block

This article briefly describes the SemNet? software and some of its uses as an educational and research tool, with emphasis on the similarities and differences between concept mapping and semantic networking. A semantic network captures (in part) each concept's position in psychological space, identifying both the other concepts to which it is connected and the nature of the links that bind them. Computer-based semantic networks differ from paper-and-pencil maps in that they are n-dimensional; each concept can be linked to many other concepts; relations are bidirectional; representations can include images, text, and sound; and nets can be very large. Disadvantages of SemNet? networks include (a) the difficulties in obtaining a clear overview and (b) the homogeneous nature of the representations, in which all links look alike. Advantages include the ability to integrate ideas across a large knowledge base, the ease and rapidity of net creation, the ease with which elements (concepts, relations, or propositions) can be found within nets, and the utility of nets as self-study tools. Concept mapping and semantic networking are complementary strategies that can be used effectively in tandem to help students learn, to help teachers teach, and to support cognitive research.     

Student and faculty perceptions of plagiarism in health sciences education

Academic misconduct is a problem encountered by many academic programmes, including programmes in the health sciences. The primary purpose of the present study was to assess doctoral student and graduate faculty perceptions of academic misconduct, specifically plagiarism. We used a cross-sectional survey design, and separate surveys were developed for students and faculty. The student survey measured student perceptions of the prevalence of plagiarism among students in general and assessed the occurrence of each student’s plagiaristic behaviours. The faculty survey measured faculty perceptions of the prevalence of plagiarism among students in general and among students in their courses specifically. Two hundred and thirty-eight students and 92 faculty completed the surveys. Students were doctoral health sciences students enrolled in a campus-based, online or hybrid programme. Compared with the self-reported behaviour of students, faculty believed more students were involved with plagiarism. Self-rated knowledge about plagiarism was significantly higher among online students and faculty than among campus-based students and faculty (p<0.001). Both students and faculty believed the most common plagiaristic activity was citing and referencing a full-text source when only the abstract was read, but only a few students reported personally doing this. Additionally, more campus-based students than online students reported working closely with another classmate on an assignment when they were not authorised to do so (p<0.001). In the present study, surveyed students and faculty believed plagiarism was prevalent among the general student population; however, few students self-reported this behaviour.
