Basic Methods for Computing Special Functions

This paper gives an overview of methods for the numerical evaluation of special functions, that is, the functions that arise in many problems from mathematical physics, engineering, probability theory, and other applied sciences. We consider in detail a selection of basic methods which are frequently used in the numerical evaluation of special functions: converging and asymptotic series, including Chebyshev expansions, linear recurrence relations, and numerical quadrature. Several other methods are available and some of these will be discussed in less detail. We give examples of recent software for special functions where these methods are used. We mention a list of new publications on computational aspects of special functions available on our website

Knowledge as power on the internet

In this study we explore how knowledge produced on the Internet can reflect objectivist or subjectivist views. These different views shape participation dynamics in the knowledge production process in ways that are bound up with power. To explore these issues, we conducted a comparative case study of websites under the Development Gateway, an initiative launched by the World Bank in 2001. We examined how objective knowledge is associated with tightly controlled processes of knowledge production dominated by an elite that limits electronic participation, while subjective knowledge is associated with processes characterized by more inclusiveness, polyvocality and (qualified) egalitarianism
