A beguiling novel that does for contemporary Kenya and its 1,000 species of birds what Alexander McCall Smith's Ladies Detective series does for BotswanaFor the past three years, the widower Mr. Malik has been secretly in love with Rose Mbikwa, a woman who leads the weekly bird walks sponsored by the East African Ornithological Society. Reserved and honorable, Malik wouldn't be noticed by a bystander in a Nairobi street?except perhaps to comment on his carefully sculpted combover. But beneath that unprepossessing exterior lies a warm heart and a secret passion.But just as Malik is getting up the nerve to invite Rose to the Nairobi Hunt Club Ball (the premier social occasion of the Kenyan calendar), who should pop up but his nemesis from his school days. The jokester Harry Khan, good-looking in a flashy way and quick of foot, has also become enraptured with the object of Malik's affection. So begins the competition cooked up by fellow members of the Asadi club: whoever can identify the most species of birds in one week's time gets the privilege of asking Ms. Mbikwa to the ball. Set against the lush Kenyan landscape rich with wildlife and political intrigue, this irresistible novel has been sold in eight countries and is winning fans worldwide.

This Element describes the development of a Theory of Mind, or mentalizing, in infancy and early childhood. Theory of Mind is a key social cognitive ability that permits children to predict and explain human behaviors by attributing mental states to other people. Understanding mental states gradually progresses from basic desires to false beliefs. The Element reviews the proximal and distal cognitive and social determinants that facilitate early Theory of Mind development. Discoveries in neuroscience contribute to understanding the ontogeny of Theory of Mind. This Element presents an overview of the main theoretical accounts of Theory of Mind development and offers suggestions for future research.

The reaction of transition metal ions with ditopic ligands containing two 2,2¿:6¿,2"-terpyridine units linked by flexible spacers can give metallosupramolecular polymers, discrete metallomacrocycles or mixtures of the two. The outcome of the coordination depends on the precise reaction conditions as well as the nature of the spacer and the transition metal salt. This thesis is concerned with the reaction between cobalt(II) salts and bis(2,2¿:6¿,2"-terpyridine) ligands in which the metal-binding domains are linked by flexible oligo(ethylene glycol) spacers. An initial study of the ligands and several model mononuclear bis(2,2¿:6¿,2"-terpyridine)cobalt(II) and (III) complexes gave some insight into the solid state and solution properties of these systems, and PGSE NMR spectroscopy was found to be a useful tool for determination of the size of both the ligands and the cobalt(III) complexes in solution. The reaction of the ditopic ligands with cobalt(II) acetate tetrahydrate in pure alcohol was found to cause the decomposition of the ligand and the formation of a mononuclear bis(4¿-alkoxy-2,2¿:6¿,2"-terpyridine)cobalt(II) complex. This reaction was extended to monotopic 4¿-substituted-2,2¿:6¿,2"-terpyridines and can be considered as a reaction giving rise to polymer end-capping units, thus influencing the final outcome of the coordination. The effect of the anion on the coordination was considered further, and the speciation of mono- and bis(2,2¿:6¿,2"-terpyridine)cobalt(II) complexes in solution was investigated using the 4¿-methoxy-2,2¿:6¿,2"-terpyridine ligand. The product mixtures were found to depend heavily on the anion, solvent and initial ratio of ligand to metal salt. Similar behaviour was observed for a model ditopic ligand. The presence of the mono(2,2¿:6¿,2"-terpyridine)cobalt(II) complexes within a system containing the ditopic ligands would also provide polymer end-capping units, influencing the speciation of these mixtures. Finally, a detailed study of the product mixtures obtained from the reactions of the ditopic ligands with cobalt(II) salts revealed a complex dependence of the speciation of many bis(2,2¿:6¿,2"-terpyridine)cobalt(II) complexes on the ligand, anion, solvent, concentration and other seemingly minor reaction parameters. Using the PGSE NMR spectroscopic technique, the sizes of some of the metallomacrocyclic species present in the equilibrium mixtures could be determined. These measurements were in excellent agreement with X-ray crystallographic data. Analysis of initial product mixtures using the same technique suggested that the initial kinetic products of the complexation are significantly larger species.
