Three Paradigms of Social Assistance

Three Unconventional Computational Paradigms

My recent work has uncovered at least three general unconventional computational paradigms within which parallel algorithms lead to a superlinear improvement in performance (that is, speed and quality) with respect to their sequential counterparts. These paradigms, described in some detail below, are: computing in real time, computing within the bounds of laws of nature, and computing subject t...

Three Paradigms of Rational Agency

The Three Paradigms of HCI

Informal histories of HCI commonly document two major intellectual waves that have formed the field: the first orienting from engineering/human factors with its focus on optimizing man-machine fit, and the second stemming from cognitive science, with an increased emphasis on theory and on what is happening not only in the computer but, simultaneously, in the human mind. In this paper, we docume...

Justice-based social assistance

What are the main objectives of social protection institutions in developing countries? What should be their scope and reach? What is the source of their legitimacy? Finding appropriate answers to these questions is essential to understanding, and shaping, the emergence of welfare institutions in low- and middle-income countries. Most available answers rely on instrumental arguments. Few make r...

Three non Conventional Paradigms of Parallel Computation

We consider three paradigms of computation where the ben-eets of a parallel solution are greater than usual. Paradigm 1 works on a time-varying input data set, whose size increases with time. In paradigm 2 the data set is xed, but the processors may fail at any time with a given constant probability. In paradigm 3, the execution of a single operation may require more than one processor, for sec...
