Primary care providers' views of precepting nurse practitioner students.

PURPOSE: To explore perceived barriers to and facilitators of precepting as viewed by experienced community-based preceptors. DATA SOURCES: Twenty-four nurse practitioner and physician preceptors participated in a 20-minute telephone interview, using a semi-structured format. The interviews were audio-taped and transcribed. Constant comparative analysis was used to organize the preceptors' responses into thematic categories. CONCLUSIONS: Overall, most preceptors were satisfied with the precepting experience; however, many preceptors cited increasing difficulty with teaching students in primary care sites due various organizational constraints such as the imperative to increase productivity. Good communication with school of nursing faculty was cited as the key factor to continued willingness to precept. IMPLICATIONS FOR PRACTICE: Understanding factors that are important for preceptors continuing in their clinical teaching role is important for schools of nursing, especially given the increasing time-limitations that many providers face due to social and economic changes in health-care delivery.

Ultrasound shear wave imaging for bone.

Recently, a computer-controlled scanning ultrasound (US) imaging system was developed in our laboratory. It includes a pair of broadband 48-MHz focusing copolymer transducers. The apertures of the transducers and their f-numbers were identically equal to 2 mm and 2.25, respectively. A specimen can be moved in a 10-microm increment in its plane and its normal direction can be rotated along the US propagation direction. It can be used to produce transmission-mode images of shear waves, as well as longitudinal waves for solid specimens. Shear waves in solids were generated by mode conversion. The results of the longitudinal and shear-wave US images for a piece of compact bovine bone obtained using this system are presented. Shear-wave images combined with longitudinal images can provide a more complete mechanical characterization of bone.
