1. Indexicality in language and thought As expression types, indexicals do not refer. Only tokens of an indexical refer, because indexical reference is achieved through relations between tokens of the indexical and other entities in the context of tokening ; entities which gain their status as referent in virtue of standing in these relations to the relevant token. For example, a token of 'I' r...

The title isochroman ( 8 ) was synthesized as a suitable substrate for acetoxylation studies leading to an intermediate of type (4), expected to afford, on condensation with diketen, the fungal metabolite "rotiorin" type linear product (1). Cyclocondensation of alcohol (6), obtained by the reduction of ketone (5) with paraform in the presence of anhydrous aluminum chloride afforded the dim...

1. Given any associative ring A one can construct from its operations and elements a new ring, the Jordan ring of A, by defining the product in this ring to be a o b = ab+ba for all a, b^A, where the product ab signifies the product of a and b in the associative ring A itself. If R is any ring, associative or otherwise, by a derivation of R we shall mean a function, ', mapping R into itself so ...
