However, a recent resurgence in industrial and research interest in silicon-germanium ensures that it will have an increasingly important role in nano- and opto-electronics. It is unavoidable that a sound understanding of the oxidation of silicon-germanium will be required as processes are developed for using the material in electronic applications. In fact, a profound appreciation for the oxidation kinetics of silicon-germanium could itself create new applications for the material. The present work investigates the use of thermal oxidation in nanostructuring of epitaxially grown silicon-germanium by examining the kinetics of oxidation and the redistribution of germanium at the oxidation interface. This is done for oxidations in dry O2 ambients with a particular focus on the influence of temperature an...

Indirect assessment procedures include care provider and client interviews, whereas direct assessment procedures involve systematically exposing participants to stimuli while recording their responses. These types of direct assessment procedures can be categorized as either approach-based or engagement-based. Approach-based procedures involve recording the individuals’ approach responses to stimuli presented singly or concurrently with other stimuli, whereas engagement-based procedures involve recording duration of engagement with stimuli. Although the predictive validity of indirect preference assessment procedures has yet to be established, using them in combination with direct measures of preferencemaybe most efficacious for identifying potential reinforcers. Recent research on preferenc...

In the present study, 6 adult women with mental retardation were trained in sexual abuse prevention, and performance was assessed using four separate measures: pretests and posttests of knowledge, verbal report, role play, and naturalistic probes. All women learned the skills but failed to exhibit them to criterion during the probes. We discuss the implications for further training and assessment of sexual abuse prevention skills.
