The purpose of this study was to assess the self-efficacy of nursing faculty and students related to their potential use of mobile technology and to ask what implications this technology has for their teaching and learning in practice education contexts. We used a cross-sectional survey design involving students and faculty in two nursing education programs in a western Canadian college. In January, 2011, 121 faculty members and students completed the survey. Results showed a high level of ownership and use of mobile devices among our respondents. The median mobile self-efficacy score was 75 on a scale of 100, indicating that both faculty and students were highly confident in their use of mobile technologies and prepared to engage in mobile learning.<br /><br />
The ability to filter distracting information and selectively attend to relevant information is critical to effective performance on the battlefield. In addition to the cognitive processing burden imposed upon modern warfighters, the effects of stress upon cognition and action must also be accounted for in evaluating individual warfighting capabilities. The current study examines the relationship between stress and cognition by measuring performance on a multiple object tracking (MOT) task after exposure to stress-inducing photographs. Postexposure performance revealed significant decrements in MOT accuracy relative to a nonstressed control group. Implications are discussed regarding the impact of stress on attentional selection for operational scenarios where it is difficult to distinguish friendly individuals from those with hostile intentions, as well as for the development of technology for command, control, communications (computers), and intelligence (C4I) systems.The benefits of advanced technological sophistication are frequently offset by human performance limitations. On today's "digital battlefield" the modern war-
_____________________________________________________________________________________________A methodology for quantifying Army rotary wing aviator performance as influenced by aircrew life support, survival, and nuclear-biologicalchemical clothing and equipment ensembles was examined in a set of experimental trials conducted in an AH-64 (Apache) combat mission simulator. The methodology was based on an aircrew evaluation procedure originally developed for use in the crew coordination training of all Army aviators. It uses a set of 13 basic qualities, each with behavioral anchors and a 7-point rating scale, and it is administered by specifically trained senior aviator evaluators. Ten crews, two aviators in each, while fully encumbered, performed three combat missions for record, representative of typical operational tasks, with one "variation" trial conducted without the over-water components of the ensemble. Measures of effectiveness and flight data, as well as stress assessment and equipment "complaints" citations, were recorded. The results indicated that the behavior-anchored scores were not sensitive enough to statistically discriminate among the independent variables of repeated measures and the variation trials even though graphically, differences were readily apparent. Attempts to apply transformations to the data, based on the aviator subjects' relative flying experience and their apparent accommodation to the trials were also statistically unsuccessful. The additional measures collected did not yield statistically significant discriminations nor did they correlate well with the evaluation scores. A number of options for improving the technique are offered. iii ACKNOWLEDGMENTSWe also offer an appreciative and hearty "well done" to that highly motivated group of associate investigators who were major contributors to this investigation by working long, long hours during the trials while maintaining their sense of humor throughout: Ms. Jean Breitenbach and Mr. Ronald Whittaker as well as co-authors Mr. Daniel Barker, Ms. Debra Patton, and Ms. Linda Mullins, HRED; and to those highly skilled instructor-operators and evaluators manning the simulator, CW3 C. David Pope, Jr., CW4 Michael Hillwig, CW5 Gary Kilker, Mr. Charles (Chip) Decker, WO2 Joseph O'Neill, WO2 Michael Wanamaker. Of course, we are extremely grateful to the aviators who participated as subjects, whom we cannot thank by name in this report. Nevertheless, they are highly commended for their dedication to the investigation as well as their willingness to tolerate strange hours and large doses of hard work and discomfort.Special gratitude is given to the people at the Western Area Aviation Training Site (WAATS), Marana, Arizona, who most graciously offered their simulation facilities for the experiment and who assisted, along with the Arizona National Guard, in the logistics of its execution: COL George Gluski, CDR, WAATS, LTC James Braman, Chief of the AH64 CMS facility; his second in command and co-author MAJ David Mitchell; Platoon Leader a...
