We present a partial classification of those finite linear spaces S on which an almost simple group G with socle PSL(3, q) acts line-transitively. A linear space S is an incidence structure consisting of a set of points Π and a set of lines Λ in the power set of Π such that any two points are incident with exactly one line. The linear space is called non-trivial if every line contains at least ...

Combining multiple sources of informationis a major and diicult task in the management of uncertainty. Dempster's combination rule is one of the attractive approaches. However, many researchers have pointed out that the application domains of the rule are rather limited and it sometimes gives unexpected results. In this paper, we have further explored the nature of combination and achieved the ...

We use the author's combinatorial theory of full heaps to categorify the action of a large class of Weyl groups on their root systems, and thus to give an elementary and uniform construction of a family of faithful permutation representations of Weyl groups. Examples include the standard representations of affine Weyl groups as permutations of Z and geometrical examples such as the realization ...

When considering health inequalities, it is essential to consider the social causes, context, and consequences of the inequalities (that is, the big picture) as well as the meanings and manifestations of the inequalities in the lives of individuals (that is, the fine grain). Or, to adopt Charles Wright Mills’s terminology in The Sociological Imagination, it is essential to be able to distinguis...
