BACKGROUND In the Plio-Pleistocene, the hominin foot evolved from a grasping appendage to a stiff, propulsive lever. Central to this transition was the development of the longitudinal arch, a structure that helps store elastic energy and stiffen the foot during bipedal locomotion. Direct evidence for arch evolution, however, has been somewhat elusive given the failure of soft-tissue to fossiliz...

The African colobines represent a neglected area of cercopithecid systematics. Resolving the phylogenetic relationships and estimating divergence dates among the living forms will provide insight into the evolution of this group and may shed light upon the evolution of other African primates as well. This is the first molecular assessment of the evolutionary relationships among the modern colob...

The polar opposite, Medicine (Primum non nocere First, do no harm), paradoxically, learned much, and in the case of surgery, probably almost everything, from conflict and war. Surgeons such as Ambroise Paré, Dominique Jean Larrey, William Beatty and Archibald McIndoe improved the lot of those for whom they cared, and left a legacy for those that would follow. So much has been written about The ...

Fragmentary post-cranial remains (femora, tibia, vertebrae) of ornithischian dinosaurs from the Late Cretaceous of the Sultanate of Oman are described and referred to hadrosauroids. The specimens come from the Al-Khod Conglomerate, of latest Campanian to Maastrichtian age, in the north-eastern part of the country. Although the fragmentary condition of the fossils precludes a precise identificat...

In general, conglomeration leads to a diversification of risks (the diversification benefit) and to a decrease in shareholder value (the conglomerate discount). Diversification benefits in financial conglomerates are typically derived without accounting for reduced shareholder value, even though a comprehensive analysis requires competitive conditions within the conglomerate, i.e., shareholders...
