Most studies into the performance of socially responsible investment vehicles have focused on the performance of sustainable or socially responsible mutual funds. This research has been complemented recently by a number of studies that have examined the performance of sustainable investment indices. In both cases, the majority of studies have concluded that the returns of socially responsible investment vehicles have either underperformed, or failed to outperform, comparable market indices. Although the impact of sustainable indices to date has been limited, the (...) recent launch of sustainable indices by Dow Jones and FTSE suggests that more attention is being paid to the subject by financial markets, investors, and companies. This development raises a number of important issues which are reviewed in this article: (a) the performance of indices compared with their benchmark indices; (b) the methodologies employed in compiling the indices; and (c) the impact of the indices on companies and the investment community. The article concludes with a number of suggestions for areas that merit future research. (shrink)
We have observed in a systematic manner 317 nuclear interactions produced by the heavy nuclei of the primary cosmic radiation in nuclear emulsions. From a study of these interactions we have found the interaction mean free paths and fragmentation probabilities. The interaction mean free path are in good agreement with those reported previously. The fragmentation probabilities, particularly those for the production of light nuclei, are considerably smaller than those currently accepted. In addition, from a study of the angular distribution of (...) the nuclei emitted from the interactions we have shown that the energies of emission in the C-system of the incident nucleus are greater than those previously accepted and depend on the charge of the primary nucleus.

As computer-based information systems start to have a great impact on people, organizations, and society as a whole, there is much debate about information technology in relation to social control and privacy, security and reliability, and ethics and professional responsibilities. However, more often than not, these debates reveal some fundamental disagreements, sometimes about first principles. In this article the authors suggest that a fruitful and interesting way to conceptualize some of these moral and ethical issues associated with the use of (...) information technology is to apply the principles of Aristotle's ethics to this topic. They argue that framing the moral and ethical choices associated with information technology in Aristotelian terms draws attention to the fact that there are fundamental dilemmas to be addressed. These dilemmas are discussed in relation to the four areas suggested by Dejoie, Fowler, and Paradice (1991): (a) privacy, (b) information accuracy, (c) access to information, and (d) intellectual property rights. The dilemmas associated with all four areas are illustrated with references to recent legal developments in Australia and New Zealand. (shrink)
