We conclude that instillation and infusion of intraperitoneal ropivacaine for patients undergoing colectomy, including by the laparoscopic approach, decreases postoperative pain and improves functional postoperative recovery. We recommend routine inclusion of intraperitoneal local anesthetic into the multimodal analgesia component of enhanced recovery after surgery programs for laparoscopic colectomy.

Participatory or joint decision-making strategies have been suggested as effective in groups with the task of solving unstructured problems or creating innovations. This longitudinal case study of a small task group suggests that there may be important differences between the desire of group participants to use participatory strategies and their ability to do so effectively. After 15 months, the group members failed to accomplish their task. Four problem areas that account for the lack of productivity are identified: expertise, self-oriented needs, permissive operating procedures, and formal status differences. Implications for other groups that attempt to use participatory strategies are discussed.

The in situ growth of p-n junctions in silicon nanowires enables the fabrication of a variety of nanoscale electronic devices. We have developed a method for selective coating of Au onto n-type segments of silicon nanowire p-n junctions. Selective plating allows for quick verification of the position of p-n junctions along the nanowire using electron microscopy and allows for measurement of segment length.
