The intensities of the Raman lines of the transition metal complexes Co(en)33+, PdCl4=, PdBr4=, and PdI4=, have been investigated as a function of excitation energy in the vicinity of vibronically allowed ligand field electronic transitions. Whereas resonance enhancement usually results in local maxima in Raman intensities at the energies of allowed electronic transitions, we observe minima at the energies of these electronically forbidden transitions. These minima are ascribable to interference between the weak scattering from the forbidden electronic states and strong preresonance scattering from higher energy allowed electronic states. The excitation profiles can be reproduced with a three-state scattering model, using reasonable parameters.

Needle/syringe combinations were collected from three shooting galleries in South Florida and tested for the presence of antibodies to HIV-1. Fifteen of 148 needles (10.1 percent) tested positive for HIV-1 antibody. Seropositivity rates did not vary by the day of the week of collection, nor by shooting gallery from which they were collected. When the needle appeared to contain blood residue, 20.0 percent were positive versus 5.1 percent with no blood

This book is about ideas at the centre of our thought about our individual lives and about society—‘well‐being’, ‘welfare’, ‘utility’, and ‘quality of life’. It aims to answer three questions: What is the best way to understand well‐being? to what extent can it be measured? what role should it play in moral and political thought? The book argues that the sharp contrast between reason and desire found in our modern intellectual tradition has hampered answers to those questions. The book first tries to describe the place of both reason and desire in our thought about well‐being. It then uses the notion of well‐being, so explained, in discussions of whether values are commensurable, of what measurement of one person's well‐being is demanded by ethics and whether it can be supplied by us, and whether we can effectively compare one person's well‐being with another's. It ends with discussions of the relation of individual well‐being to morality in general, to equality, fair constitution, rights, punishment and rewards, and distribution.
