    Discursive design thinking: the role of explicit knowledge in creative architectural design reasoning

    The main hypothesis investigated in this paper is based upon the suggestion that the discursive reasoning in architecture supported by an explicit knowledge of spatial configurations can enhance both design productivity and the intelligibility of design solutions. The study consists of an examination of an architect’s performance while solving intuitively a well-defined problem followed by an analysis of the spatial structure of their design solutions. One group of architects will attempt to solve the design problem logically, rationalizing their design decisions by implementing their explicit knowledge of spatial configurations. The other group will use an implicit form of such knowledge arising from their architectural education to reason about their design acts. An integrated model of protocol analysis combining linkography and macroscopic coding is used to analyze the design processes. The resulting design outcomes will be evaluated quantitatively in terms of their spatial configurations. The analysis appears to show that an explicit knowledge of the rules of spatial configurations, as possessed by the first group of architects can partially enhance their function-driven judgment producing permeable and well-structured spaces. These findings are particularly significant as they imply that an explicit rather than an implicit knowledge of the fundamental rules that make a layout possible can lead to a considerable improvement in both the design process and product. This suggests that by externalizing th

    What should a robot learn from an infant? Mechanisms of action interpretation and observational learning in infancy

    The paper provides a summary of our recent research on preverbal infants (using violation-of-expectation and observational learning paradigms) demonstrating that one-year-olds interpret and draw systematic inferences about other’s goal-directed actions, and can rely on such inferences when imitating other’s actions or emulating their goals. To account for these findings it is proposed that one-year-olds apply a non-mentalistic action interpretational system, the ’teleological stance’ that represents actions by relating relevant aspects of reality (action, goal-state, and situational constraints) through the principle of rational action, which assumes that actions function to realize goal-states by the most efficient means available in the actor’s situation. The relevance of these research findings and the proposed theoretical model for how to realize the goal of epigenetic robotics of building a ’socially relevant’ humanoid robot is discussed

    A Visibility and Spatial Constraint-Based Approach for Geopositioning

    Get PDF
    Over the past decade, automated systems dedicated to geopositioning have been the object of considerable development. Despite the success of these systems for many applications, they cannot be directly applied to qualitative descriptions of space. The research presented in this paper introduces a visibility and constraintbased approach whose objective is to locate an observer from the verbal description of his/her surroundings. The geopositioning process is formally supported by a constraint-satisfaction algorithm. Preliminary experiments are applied to the description of environmental scenes

    Process Based Management and the Central Role of Dialogical Collective Activity in Organizational Learning. The Case of Work Safety in the Building Industry

    The notion of “process”, which describes the cooperation of heterogeneous practices and competences for a given output, has gained a major position in managerial practices for the last twenty years. This paper presents three ideas about organizational dynamics and processes and tests their applicability in the case of work safety improvement in a building company. The first idea is that the success of the process notion shows the central role of “conjoint” (as opposed to “common”) collective activity in organizational learning. Conjoint collective activity is dialogical (“acts speak”) and mediated by the utilization of semiotic systems (languages and technical and managerial tools). The second idea is that organizational learning is neither based on the actors’ individual subjectivity nor on the technological and objective artefacts engaged in the processes, but rather on the reflexive understanding and ongoing redesign of processes by the process actors themselves, in the frame of a reflexive inquiry, a “collective activity about collective activity” which is triggered and kept in motion by axiological judgments (process evaluation). The third idea is that the possibilities to configure processes in a given organization are multiple. The reflexive inquiry enacts a specific social, spatial and time configuration of the process, its “chronotope” in Bakhtin’s vocabulary, which plays a major role in the way actors can make sense of their collective activity and transform it. A longitudinal case study about work safety on the building yards shows that it is difficult to “control out” risk at work once designs have been established, in the frame of the “project execution” process, but it is easier to “design out” risk, when the actors of the process collectively design and redesign their collective activity, from the very first phases of a building project to the end. Therefore a major way to improve safety consists in extending the chronotope of the collective activity under consideration, overcoming the traditional separation between “design / planning” and “execution”. The conclusion summarizes the main theoretical, epistemological and practical issues involved in this research about conjoint collective activity.Business Process; Chronotope; Collective Activity; Collective Sense Making; Dialogism; Inquiry; Process-based Management; Safety Management
