the well-known tendency of particular maladies to show breed-specificity can be used to infer likely sharing of descent of the causative alleles. As made clear in the volume under review, this is as true of major-gene diseases such as copper toxicosis and various retinopathies, as it is of the more complex and more prevalent cardiomyopathies, cancers, and dermatitis. Conduction of clinical tria...

Major histocompatibility complex (MHC) 1 genes, in particular those encoded in the I region of the murine H-2, have been shown to be of functional importance in several aspects of immune response regulation. Thus, I region-encoded immune response (It) genes determine responsiveness or unresponsiveness to a number of antigens (1); and T cell recognition of I region gene products is critical for ...

Suppose that r and n are non-negative integers satisfying r + n > 0. Denote the moduli stack over SpecZ of smooth elliptic curves with n marked points and r non-zero tangent vectors by M1,n+r⃗. Here the n marked points and the anchor points of the r tangent vectors are distinct. Taking each tangent vector to its anchor point defines a morphism M1,n+r⃗ → M1,n+r that is a principal Gm-bundle. The D...

Permutations of finite sets play a central role in algebraic and enumerative combinatorics. In addition to having many interesting enumerative properties per se, permutations also arise in almost every area of mathematics and indeed in all the sciences. Here we will discuss three different topics involving permutations, focusing on combinatorics but also giving some hints about connections with...

This article is concerned with problems of comparative research and analysis in industrial relations, and in particular with cross-national comparison of trade unions. Comparison is of both practical and theoretical importance, but is fraught with difficulties, in part because of the paradox involved in attempting to generalise concerning national instances which are in so many respects unique....

In this article, we study the structures that the Greek language employs to express quantification. By Greek, I am referring to the contemporary Greek spoken in the countries of Greece and Cyprus (an estimated total of 14 million speakers), and Greeks in diaspora (an estimated 5–6 million). It has long been customary, especially in the study of classics, to use the term ‘Greek’ to refer to the ...
