چکیده
The metaphysical assumptions of cognitive science are explored with the goal to develop a problem-centered science relevant to the design and engineering of effective products and technologies. Radical Empiricism is suggested as an ontological foundation for pursuing this goal. This ontology poses a single reality where mind and matter come together to shape experience. Peirce’s triadic semiotic system is suggested as a framework for parsing this reality in ways that reveal important aspects of the dynamics of communication and control. Rasmussen’s three analytic frames of the 1) Abstraction Hierarchy, 2) the Decision Ladder, and 3) Ecological Interface Design are suggested as important tools for achieving insight into the dynamics of this triadic semiotic system. These ideas are offered as a challenge to both scientists and designers to reassess the basic assumptions that guide their work. The hope is that by facing these challenges we can take the first tentative steps toward a coherent science of what matters.

However, whatever the technique, the most impor...

متن کاملCombined Phaco Trabeculectomy Vs Combined ECCE Trabeculectomy with IOL Implantation
Results: Postoperative IOP in both groups fell significantly (P=<0.05) below the preoperative medically controlled IOP. At initial 2 months postoperative IOP was almost similar in bothgroups (mean IOP in phacotrab group was 11 mm Hg vs mean IOP in ECCE trab group as 13 mm Hg i.e P= >.050). At 12 months, the IOP in phacotrab group was lower than ECCE trab group. Postoperative visual recovery was...

متن کاملThe ecce Partial Deduction System
We present the fully automatic partial deduction system ecce, which can be used to specialise and optimise logic programs. We describe the underlying principles of ecce and illustrate some of the potential application areas. Interesting possibilites of crossfertilisation with other elds such as reachability analysis of concurrent systems and inductive theorem proving are highlighted and substan...
