    Child development and the aims of road safety education

    Pedestrian accidents are one of the most prominent causes of premature injury, handicap and death in the modern world. In children, the problem is so severe that pedestrian accidents are widely regarded as the most serious of all health risks facing children in developed countries. Not surprisingly, educational measures have long been advocated as a means of teaching children how to cope with traffic and substantial resources have been devoted to their development and provision. Unfortunately, there seems to be a widespread view at the present time that education has not achieved as much as had been hoped and that there may even be quite strict limits to what can be achieved through education. This would, of course, shift the emphasis away from education altogether towards engineering or urban planning measures aimed at creating an intrinsically safer environment in which the need for education might be reduced or even eliminated. However, whilst engineering measures undoubtedly have a major role to play in the effort to reduce accidents, this outlook is both overly optimistic about the benefits of engineering and overly pessimistic about the limitations of education. At the same time, a fresh analysis is clearly required both of the aims and methods of contemporary road safety education. The present report is designed to provide such an analysis and to establish a framework within which further debate and research can take place

    Simulating activities: Relating motives, deliberation, and attentive coordination

    Get PDF
    Activities are located behaviors, taking time, conceived as socially meaningful, and usually involving interaction with tools and the environment. In modeling human cognition as a form of problem solving (goal-directed search and operator sequencing), cognitive science researchers have not adequately studied “off-task” activities (e.g., waiting), non-intellectual motives (e.g., hunger), sustaining a goal state (e.g., playful interaction), and coupled perceptual-motor dynamics (e.g., following someone). These aspects of human behavior have been considered in bits and pieces in past research, identified as scripts, human factors, behavior settings, ensemble, flow experience, and situated action. More broadly, activity theory provides a comprehensive framework relating motives, goals, and operations. This paper ties these ideas together, using examples from work life in a Canadian High Arctic research station. The emphasis is on simulating human behavior as it naturally occurs, such that “working” is understood as an aspect of living. The result is a synthesis of previously unrelated analytic perspectives and a broader appreciation of the nature of human cognition. Simulating activities in this comprehensive way is useful for understanding work practice, promoting learning, and designing better tools, including human-robot systems

    Interpreting Practice: Dilthey, Epistemology, and the Hermeneutics of Historical Life

    Get PDF
    This paper explores Dilthey’s radical transformation of epistemology and the human sciences through his projects of a critique of historically embodied reason and his hermeneutics of historically mediated life. Answering criticisms that Dilthey overly depends on epistemology, I show how for Dilthey neither philosophy nor the human sciences should be reduced to their theoretical, epistemological, or cognitive dimensions. Dilthey approaches both immediate knowing and theoretical knowledge in the context of a hermeneutical phenomenology of historical life. Knowing is not an isolated activity but an interpretive and self-interpretive practice oriented by situated reflexive awareness and self-reflection. As embedded in an historical relational context, knowing does not only consist of epistemic validity claims about representational contents but is fundamentally practical, involving all of human existence. Empirically informed Besinnung, with its double reference to sense as meaning and bodily awareness, orients Dilthey’s inquiry rather than the “irrationalism” of immediate intuition or the “rationalism” of abstract epistemological reasoning

    Anticipatory Mobile Computing: A Survey of the State of the Art and Research Challenges

    Get PDF
    Today's mobile phones are far from mere communication devices they were ten years ago. Equipped with sophisticated sensors and advanced computing hardware, phones can be used to infer users' location, activity, social setting and more. As devices become increasingly intelligent, their capabilities evolve beyond inferring context to predicting it, and then reasoning and acting upon the predicted context. This article provides an overview of the current state of the art in mobile sensing and context prediction paving the way for full-fledged anticipatory mobile computing. We present a survey of phenomena that mobile phones can infer and predict, and offer a description of machine learning techniques used for such predictions. We then discuss proactive decision making and decision delivery via the user-device feedback loop. Finally, we discuss the challenges and opportunities of anticipatory mobile computing.Comment: 29 pages, 5 figure
