Discursos técnico-cientÃficos en la construcción social y polÃtica de la Reserva de la Biósfera de la Sierra Gorda en Querétaro
Los estados-nación modernos han adoptado el modelo de Reservas de la Biósfera como la herramienta polÃtica por excelencia para la conservación de la biodiversidad. Estos espacios naturales son concebidos desde una lógica de racionalidad moderna donde el conocimiento técnico-cientÃfico ocupa un papel central en la gestión. Aunque los gestores requieren del conocimiento que producen los académicos para llevar a cabo su labor y viceversa, en la Reserva de la Biósfera de la Sierra Gorda queretana, el conocimiento técnico-cientÃfico producido por la academia es percibido como algo ajeno y fuera de la realidad, mientras que los académicos de la Universidad Autónoma de Querétaro consideran que no se está llevando a cabo una gestión adecuada de la Reserva. Es justamente en esta disputa entre saberes modernos donde se sitúan los aportes de esta tesis. Los resultados se obtuvieron a través del análisis del discurso y de la Schemata de Praxis y dan cuenta de las visiones confrontadas que estos grupos tienen en torno a la naturaleza, al conocimiento técnico-cientÃfico y al desarrollo. El reflexionar sobre esta confrontación discursiva brinda elementos para establecer modelos de gestión centrados en el lugar que contribuyan a la construcción social y polÃtica de un medio ambiente donde los saberes hÃbridos puedan ocupar una posición más equitativa
Reframing HRI Education : A Dialogic Reformulation of HRI Education to Promote Diverse Thinking and Scientific Progress
Over the last few years, technological developments in semi-autonomous machines have raised awareness about the strategic importance of human-robot interaction (HRI) and its technical and social implications. At the same time, HRI still lacks an established pedagogic tradition in the coordination of its intrinsically interdisciplinary nature. This scenario presents steep and urgent challenges for HRI education. Our contribution presents a normative interdisciplinary dialogic framework for HRI education, denoted InDia wheel, aimed toward seamless and coherent integration of the variety of disciplines that contribute to HRI. Our framework deemphasizes technical mastery, reducing it to a necessary yet not sufficient condition for HRI design, thus modifying the stereotypical narration of HRI-relevant disciplines and creating favorable conditions for a more diverse participation of students. Prospectively, we argue, the design of an educational 'space of interaction’ that focuses on a variety of voices, without giving supremacy to one over the other, will be key to successful HRI education and practice.Action and intention recognition in human interaction with autonomous systems -AI
Enabling small-scale methanol synthesis reactors through the adoption of highly conductive structured catalysts
reserved6We present herein a modeling study of two innovative highly conductive structured multi-tubular reactors (SR) for the methanol synthesis, loaded with copper honeycomb monoliths (HM) and open-cell foams (OF), respectively, and discuss their performances in comparison with those of the state-of-the-art commercial Lurgi multi-tubular packed-bed (PB) reactor. We simulate the complete process loop (including reactor and condenser) for this purpose. By parametric analysis of changes in feed gas composition and reactor tube length, we show that, when short tubes are employed, conductive SR outperform PB reactors, in which the heat transfer worsens when low gas flow rates are employed. Simulations suggest that compact SR for methanol synthesis can be indeed operated with limited hot-spot temperatures and reasonable recycle ratios.A. Montebelli; C.G. Visconti; G. Groppi; E.
