In this article we examine the introduction of digital video pedagogy into dynamic workplaces with fast-changing social and material environments, and discuss its potential to participate in producing forms of positive change. The discussion brings together two strands: we investigate workplace learning theoretically as it emerges as part of a digital material world; and we consider how we might re-think workplace learning through possibilities of digital technologies. We develop this discussion through the example of how digital video has been used to engender new ways of learning and knowing about safety in one of the most dangerous workplaces globally - the construction industry.
Abstract
The latency of food retrieval and other behaviours in the presence of a live boa constrictor and other snake-like stimuli was observed in three groups of squirrel monkeys (adult feral, adult laboratory reared, and immature laboratory reared). The principal results were as follows: 1. Both of the laboratory reared groups retrieved food within about five or fewer sec in the presence of any stimulus, including the live snake. 2. The retrieval latencies of the adult feral group were longest in the presence of the live snake, the next longest in the presence of rubber snakes painted either gray or an approximation of the boa constrictor markings, and shortest in the presence of various rubber tubes or a gray block. This result suggests that avoidance of some snake like stimuli in the adult feral squirrel monkey is determined more by shape than by markings. 3. The habituation of the snake avoidance response was rapid for all stimuli, but occurred more slowly for the live snake than for the two rubber snakes. 4. Of the various behaviors observed in the interval between the presentation and the retrieval of food, visual scanning was predominant and occurred during 74 percent of this time.
