The composition graph of a family of n+1 disjoint graphs {Hi : 0 ≤ i ≤ n} is the graph H obtained by substituting the n vertices of H0 respectively by the graphs H1, H2, ..., Hn. If H has some hereditary property P , then necessarily all its factors enjoy the same property. For some sort of graphs it is sufficient that all factors {Hi : 0 ≤ i ≤ n} have a certain common P to endow H with this P ...

Working at the Crossmodal Research Laboratory in Oxford, Charles Spence tries to apply the latest insights from our growing neuroscience understanding of the rules governing multisensory integration to the design of better products, packages, places, interfaces, and foods, an area that can perhaps best be captured under the title of neuroscience-inspired multisensory design.

Few would dispute the claim that Charles Edward Spearman (1863-1945) is Britain’s premier psychologist and indeed one of the enduring figures in the history of behavioral science. Some twenty years ago, I asked a number of psychologists to list the names of whomever they considered to be the five or six most important persons in the history of psychological testing. Among all the nominations, o...

Pergamon Press, which has in recent years taken interest in matters neurophysiological, has collected the writings of 56 authors, from many countries, dealing with biochemical, physiological, pharmacological and behavioral aspects of nervous function. Most of the material is a succinct compilation of previously published observations; but some of it, such as the study by Smith, Stacey and Young...

1 . Introduction In a previous paper [2] the senior author discussed many problems concerning block designs . Some of these have since been settled . Szemerédi and Trotter [5] showed, for example, that the number of pairwise balanced designs which can be obtained geometrically on n points in the plane with the blocks being the lines joining these points is at most exp(c/) . In [1] Colbourn, Phe...

The twoand all-terminal reliabilities of the Brecht-Colbourn ladder and the generalized fan have been calculated exactly for arbitrary size as well as arbitrary individual edge and node reliabilities, using transfer matrices of dimension four at most. While the all-terminal reliabilities of these graphs are identical, the special case of identical edge (p) and node (ρ) reliabilities shows that ...

This paper examines social and technical factors that influence the acceptance of E-government technologies by public organizations. In regards to public organizations, IT acceptance is defined as “the belief that the organization will integrate a specific IT innovation into its service production processes and the potential for the organization to routinely rely on the innovation in order to a...

the present study investigates the antioxidant potential of the ethyl acetate fraction of the aerial parts eclipta alba l. hassk (eaea) which was widely used as hepatoprotective plant. eaea was orally administered at doses of 50, 100 and 200 mg/kg for 7 days in male charles foster rats. the extent of hepatoprotective potential of e . alba was studied by assessing the biochemical parameters like...
