Transfer of human chromosomes via human minisegregant cells into mouse cells and the quantitation of the expression of hypoxanthine phosphoribosyltransferase in the hybrids.
(J Cell Sci, 1978-04)
The behaviour of human cells arrested in mitosis can be severely perturbed so as to generate numerous small minisegregants containing very few chromosomes. These cells can be separated according to size and DNA content and ...

Economic Theory and Society: A Plea for Process Analysis
That the social sciences have grown up linked with their subject matter presents a unique challenge to historians. They have not only to unravel the complex strands in the evolution of theory but have also to discover the ...
Price expectations, disequilibrium adjustments, and macroeconomic price stability
In two previous papers we have discussed the formulation of a logically consistent adaptive-type price expectations mechanism in continuous time and have applied our results to derive sufficient conditions for dynamic price ...
Technical Change and Firm Size: The Pharmaceutical Industry
The plan of this paper is as follows: First, we summarize and point out several problems we found with Comanor's study. Section III presents the results from a two-equation model that decomposes the technical change measure ...

Optimal Critical Values for Pre-Testing in Regression
In this paper we derive and present optimal critical points for pre-tests in regression using a minimum average relative risk criterion. We use the same type risk functions as Sawa and Hiromatsu  who, in a recent paper ...
Estimation of variance after a preliminary test of homogeneity and optimal levels of significance for the pre-test
The question of whether to pool two samples in variance estimation is often decided via a preliminary F test. In this paper we show that the optimal pre-test F value is unity for a onesided alternative, where the objective ...
