Book Description
We present new results from the study of B decays at SLD: a measurement of the inclusive double-charm branching fraction in B-hadron decays and a search for the rare exclusive charmless decays B+ --> rho0pi+(K+) and B+ --> K*0pi+(K+). Using a novel technique which consists of counting charged kaons produced at the secondary (B) vertex and the tertiary (D) vertex, we measure B(B --> D anti-DX) = 0.188 + over -0.025(stat)+ over - 0.059(syst). Another technique, based on the comparison of the charge of the D vertex to the flavor of the B hadron at production, yields a consistent result. In the search for rare exclusive B+ decays, no candidates were found and competitive branching ratio upper limits are derived.

Book Description
Highly controversial when it was first published in 1981, Alasdair MacIntyre's After Virtue has since established itself as a landmark work in contemporary moral philosophy. In this book, MacIntyre sought to address a crisis in moral language that he traced back to a European Enlightenment that had made the formulation of moral principles increasingly difficult. In the search for a way out of this impasse, MacIntyre returns to an earlier strand of ethical thinking, that of Aristotle, who emphasised the importance of 'virtue' to the ethical life. More than thirty years after its original publication, After Virtue remains a work that is impossible to ignore for anyone interested in our understanding of ethics and morality today.
