Key Words:

SUMMARY Diagnostic residual and partial residual plots are proposed to identify nonlinearity in covariates for generalized linear models. It is shown that these plots are complement each other in the detection of nonlinearity. In addition, a transformed additive model which allows the resulting residual and partial residual plots to be obtained through the standard least squares approach is pro...

Key words: vegetarianism, diabetes mellitus

Vegetarianism is an old classic eating behavior that leads to lessening of several health risk factors. Vegetarian diet is reported to improve control of blood glucose concentration, to lower insulin requirement and to aid in weight control in diabetic patients.

Key Words, Culture and Cognition

How much does language influence how we think? How far are the categories of our language contingent and culture-specific? Few questions are of greater significance to the social sciences. In this paper we attempt to demonstrate that linguistic semantics can address these questions with rigour and precision, by analysing some examples of cultural 'key words' in several languages. We want to arg...

20 09 Diameter of Reduced Words

For finite reflection groups of types A and B, we determine the diameter of the graph whose vertices are reduced words for the longest element and whose edges are braid relations. This is deduced from a more general theorem that applies to supersolvable hyperplane arrangements.
