Such models tend to focus on active information seeking, to the neglect of less-directed practices. Models are often based on studies of scholars or professionals, and many have been developed using a cognitive approach to(More)
We have studied the severity and duration of nocturnal hypoxaemia before operation and for the first five nights after operation after elective major abdominal vascular surgery. Oxygen supplementation was almost 100% effective in keeping oxygen saturation greater than 90% during the early postoperative period; however, 50% of patients spent prolonged(More)
Forty patients with fractured neck of femur were allocated randomly to undergo surgery under general anaesthesia (GA) or subarachnoid anaesthesia (SAB). After operation, the incidence of deep vein thrombosis (DVT), assessed by venography, was found to be 40% in the SAB group, which was significantly lower than the incidence (76.2%) in the GA group. These(More)
One hundred patients presenting for surgical treatment of fractured neck of femur were allocated to receive either spinal (SAB) or general (GA) anaesthesia. Before operation, the mean PaO2 was 9.04 kPa. There was a significant decrease in PaO2 of 0.68 kPa in GA group at 1 h after operation, while blood-gas values were unchanged in SAB group. Eight patients(More)
Studies of everyday life information seeking have begun to attend to incidental forms of information behavior, and this more inclusive understanding of information seeking within broader social practices invites a con-structionist analytical paradigm. Positioning theory is a constructionist framework that has proven useful for studying the ways in which(More)
