Moment computation in shift invariant spaces
An algorithm is given for the computation of moments of f ∈ S, where S is either a principal h‐shift invariant space or S is a finitely generated h‐shift invariant space. An error estimate for the rate of convergence of our scheme is also presented. In so doing, we obtain a result for computing inner products in these spaces.

Direct and strong converse inequalities for approximation with Fejér means
We present upper and lower estimates of the error of approximation of periodic functions by Fejér means in the Lebesgue spaces L2πp{L}_{2{\pi }}^{p}. The estimates are given in terms of a K-functional for 1≤p≤∞1\le p\le \infty and in terms of the first ...

On approximation of functions and their derivatives by quasi‐Hermite interpolation
In this paper, we consider the simultaneous approximation of the derivatives of the functions by the corresponding derivatives of quasi‐Hermite interpolation based on the zeros of (1 − x2)pn(x) (where pn(x)is a Legendre polynomial). The corresponding approximation degrees are given. It is shown that this matrix of nodes is almost optimal.

A pointwise approximation theorem for linear combinations of Bernstein polynomials
Recently, Z. Ditzian gave an interesting direct estimate for Bernstein polynomials. In this paper we give direct and inverse results of this type for linear combinations of Bernstein polynomials.

A method of summability of Lagrange interpolation
The author uses in this paper a technique from numerical integration (see [9]) to get a discretely defined operator, which is a modification of the Lagrange operator. Therefore we improve with the linear summation method a result presented in [12] and we also point out a solution for a problem of P.L.Butzer in the proceedings of the Budapest conference

The changing Buddhist landscape: Anxiety and the development of Pure Land Buddhism in medieval China
Abstract The introduction of Pure Land practice and belief into medieval China changed the Buddhist landscape. Pure Land Buddhism offered a new pathway and new methods for achieving enlightenment. However, these changes were also a significant source of anxiety among the early community of Pure Land practitioners.
