In The Mismeasure of Man (1981) Stephen Jay Gould provides a typically readable history of one of our most vexatious intellectual enterprises: the scientific study of intelligence. Gould is successful, as always, in rendering the relevant scientific debates accessible to general readers. What Gould does less well is to carry through his attack on prior attempts to understand natural intelligenc...

The study of Hamiltonian graphs began with Dirac’s classic result in 1952. This was followed by that of Ore in 1960. In 1984 Fan generalized both these results with the following result: If G is a 2-connected graph of order n and max{d(u), d(v)}≥n/2 for each pair of vertices u and v with distance d(u, v)=2, then G is Hamiltonian. In 1991 Faudree–Gould–Jacobson–Lesnick proved that if G is a 2-co...

The nearby, 30 to 40 Myr old, starburst region of the Gould Belt has formed numerous massive stars. Within its ∼300 pc radius, it produces core-collapse supernovae at an enhanced rate which is shown to be 75 to 95 Myr kpc, i.e. 3 to 5 times higher than the local Galactic rate, over the past and future few million years. A population of persistent, but unidentified, γ-ray sources has been recent...

The local velocity field of young stars is dominated by the galactic rotation, the kinematics of the Gould Belt and the nearest OB associations and open clusters, and the kinematics of the spiral structure. We reexamined here this local velocity field by using a large sample of nearby O and B stars from the Hipparcos Catalogue. The high quality astrometric data are complemented with a careful c...

Introduction Throughout history, there has never been such a plethora of wound treatment choices and it is now an exciting and expanding field of care. However, wound management is often undertaken by health-care professionals who have not received sufficient training in this specialty (King, 2000) and this undoubtedly means that dressings are sometimes used inadvisably or inappropriately (Bux ...
