Creating spaces in intensive care for safe communication : a video-reflexive ethnographic study

The built environment in acute care settings is a new focus in patient safety research, with few studies focusing primarily on the design of ward environments and the location and choice of material objects such as light fittings and hand-washing basins.

Video Game Training and Reaction Time Skills Among Older Adults

The aim of the current study was to examine whether reaction time (RT) among older adults could be improved through video game training. Twenty-nine participants between the ages of 50 and 84 either played (N = 14) or did not play (N = 15) a video game, Pac-Man: Adventures in Time. All participants completed a pre- and postassessment of RT. Results from this study showed that there were no significant differences between the control and experimental groups on RT performance across time. These findings indicate that the amount of training provided may have been inadequate to improve RT skills. It is therefore important to investigate the amount of training required to allow older adults to respond faster to environmental stimuli and transfer skills to activities of daily living.

Spike sorting using locality preserving projection with gap statistics and landmark-based spectral clustering

Understanding neural functions requires knowledge from analysing electrophysiological data. The process of assigning spikes of a multichannel signal into clusters, called spike sorting, is one of the important problems in such analysis. There have been various automated spike sorting techniques with both advantages and disadvantages regarding accuracy and computational costs. Therefore, developing spike sorting methods that are highly accurate and computationally inexpensive is always a challenge in the biomedical engineering practice.

Quantification of spatial and thematic uncertainty in the application of underwater video for benthic habitat mapping

This study presents an analysis of the application of underwater video data collected for training and validating benthic habitat distribution models. Specifically, we quantify the two major sources of error pertaining to collection of this type of reference data. A theoretical spatial error budget is developed for a positioning system used to co-register video frames to their corresponding locations at the seafloor. Second, we compare interpretation variability among trained operators assessing the same video frames between times over three hierarchical levels of a benthic classification scheme. Propagated error in the positioning system described was found to be highly correlated with depth of operation and varies from 1.5m near the surface to 5.7m in 100m of water. In order of decreasing classification hierarchy, mean overall observer agreement was found to be 98% (range 6%), 82% (range 12%) and 75% (range 17%) for the 2, 4, and 6 class levels of the scheme, respectively. Patterns in between-observer variation are related to the level of detail imposed by each hierarchical level of the classification scheme, the feature of interest, and to the amount of observer experience. © 2014 Copyright © Taylor & Francis Group, LLC.

Using video to promote pre-service teachers’ thinking about their transition to teaching

This paper reports on research investigating the use of video representations of first-year teachers’ experiences in undergraduate teacher education workshops that focus on the transition to teaching. The use of the video is a responsive act that draws on the notion of looking back, where graduates in their first year of teaching ‘speak to’ current students. Scenes from video footage of the theatre-based research performance The First Time shaped workshop activities and discussions in the unit. Themes ranged from pedagogical to practical, covering topics such as teacher identity discourses; epiphanic and revelatory moments of transition to becoming a teacher; and preparing for job applications and interviews. Data from the researcher’s journal, Student Evaluation of Teaching and Units (SETU) comments, and semi-structured interviews with undergraduate students upon completion of the workshops are framed within a phenomenographic paradigm. The aim in phenomenography is to describe variations of conception that people have of a particular phenomenon (Sin, 2010), in this case the video as a tool to promote critical thinking about the transition to teaching. The researcher explored her own, and participants’ experiences, and identified a range of conceptual meanings of the phenomenon. These were classified into categories according to their similarities and differences concerning the effectiveness of this specific video in assisting undergraduates in their transition to teaching. Early results reveal some similarities and many variations among participants as to the effectiveness of the video as a tool. Their conceptions of the phenomenon are individual and relational, and as such are quite varied. Emergent varied themes include: ‘I know what it is that I need to learn’; ‘Is this theory or practice?’; and ‘I don’t do drama’. Emergent similarities include: ‘Preparing for the unexpected’.
