Radial velocity surveys have revealed up to now about 115 extra-solar planets, among which a few multi-planetary systems. The discovered planets present a wide variety of orbital elements and masses, which are raising many problems and questions regarding the processes involved in their formation. The statistical analysis of the distributions of orbital elements, planetary masses, and relations between these, is however already giving some strong constraints on the formation of the planetary systems. Furthermore, the study of the planet host stars has revealed the crucial role of the stellar metallicity on the giant planet formation. In this paper we will review the current status of the research on this subject.

Specially-designed microlensing searches, some of which have been underway for several years, are sensitive to extrasolar planets orbiting the most common stars in our Galaxy. Microlensing is particularly well-suited to the detection of Jupiter-mass planets orbiting their parent stars at several AU. Since Jovian analogs are thought to influence the subsequent evolution of most planetary systems, they are particularly important to study. The orbital radii and distances to the planetary systems probed by microlensing are larger than those currently studied by radial velocity techniques; the two methods are thus complementary. Recent results from microlensing searches are discussed, including constraints on Jovian analogs orbiting typical Galactic stars. Benefits and drawbacks of the technique for the characterization of planetary systems, and future prospects are briefly reviewed.

The second edition of The Oxford Handbook of Personality and Social Psychology captures the history, current status, and future prospects of personality and social psychology—presented not as a set of parallel accounts, but as an integrated perspective on the behavior of persons in social contexts. This handbook combines these two fields in a single integrated volume, offering a unique and generative agenda for psychology. It is dedicated to the proposition that personality and social psychology are best viewed in conjunction with one another and that the synergy to be gained from considering links between the two fields can do much to move both fields forward and to enrich our understanding of human nature. Such interdependence is particularly crucial if one wishes to address the ongoing functioning of persons in their natural environments, where splits between person and situation are not so easily fashioned. The chapters of the Handbook weave together work from personality and social psychology, not only in areas of long-standing concern, but also in newly emerging fields of inquiry, addressing both distinctive contributions and common ground. In so doing, they offer compelling evidence for the power and the potential of an integrated approach to personality and social psychology.
