ABSTRACT
Students are less likely to hear and understand teacher-delivered directions or instructions when they are attending to other activities (e.g., a classmate, a previously assigned task). A classroom management system known as the Color Wheel System includes rules and transition procedures designed to increase the probability that students stop their current activities and attend to teachers as they deliver directions or instructions for the next activity. A withdrawal design was used to evaluate the effects of the Color Wheel System on a teacher's repeated directions in a first-grade general-education classroom. Results showed large and immediate decreases in teacher repeated directions both times the Color Wheel System was applied and an immediate increase when it was withdrawn. Discussion focuses on limitations and directions for future longitudinal research evaluating the effects of the Color Wheel System on uninterrupted teaching and learning time, classroom climates, student-teacher relationships, and compliance.

ABSTRACT
Non-invasive prenatal diagnosis (NIPD) is a rapidly advancing approach that allows diagnostic testing based on analysis of cell free DNA in maternal plasma. This study aimed to explore the views of health professionals regarding the use of NIPD for BRCA1/2 mutations. Qualitative semi-structured interviews were conducted with eight participants. Whilst participants viewed NIPD in general as a positive step forward in prenatal testing, they were cautious about its use for BRCA testing. Significant ethical concerns emerged regarding testing prenatally for an adult onset condition, that is not fully penetrant, and the possibility of abrogating the rights of the future child to genetic autonomy. Nevertheless, participants did identify some situations whereby the test might be beneficial, such as for individuals with very negative and traumatic personal experiences of cancer desiring reassurance or wanting to prevent passing on the condition. NIPD was also seen as having benefits over invasive testing and pre-implantation genetic diagnosis, the only other options currently available to test prenatally for this condition. Exploring the views of a wider range of clinical specialties as well as patients at risk of hereditary breast cancer would be beneficial.
