Computerization of general practice is an international phenomenon. Many of the Electronic Patient Record (EPR) systems have developed organically with considerable variation in their interface and functionality. Consequently they have differing impact on the clinical consultation. There is a dearth of tools available to study their impact on the… (More)
In this paper, we discuss a computational approach to the cognitive task of social planning. First, we specify a class of planning problems that involve an agent who attempts to achieve its goals by altering other agents' mental states. Next, we describe SFPS, a flexible problem solver that generates social plans of this sort, including ones that include… (More)
Humans exhibit the remarkable ability to solve complex, multi-step problems despite their limited capacity for search. We review the standard theory of problem solving, which posits that heuristic guidance makes this possible, but we also note that most studies have emphasized the role of domain-specific heuristics, which are not available for unfamiliar… (More)
In this paper, we present a theory that aims to reproduce behavioral abilities that humans use to generate and execute their plans. We begin by highlighting the phenomena we are interested in, and then present several theoretical claims that account for them. Next, we introduce FPE, a five-stage system that supports strategies for flexible execution,… (More)
Kenya ranks among the twenty-two countries that collectively contribute about 80% of the world's Tuberculosis cases; with a 50-200 fold increased risk of tuberculosis in HIV infected persons versus non-HIV hosts. Contemporaneously, there is an increase in mobile penetration and its use to support healthcare throughout Africa. Many are skeptical that such… (More)
In this paper, we review the standard theory of human problem solving developed by Newell, Shaw, and Simon, along with limitations that have emerged since its introduction. We argue that the theory's emphasis on means-ends analysis is problematic, in that people may use a variety of other strategies to solve novel tasks. However, some aspects of their… (More)
We present a theory that aims to reproduce the fundamental characteristics of human problem solving, including the ability to use a diverse range of strategies and to incorporate domain expertise when available. To begin, we discuss some known features of problem solving and propose several theoretical assumptions to account for them. Next, we introduce… (More)
