Power and Plenty: Trade, War and the World Economy in the Second Millennium (Preface)

This book provides the first systematic, integrated, analytical account of the evolution of the international economy during the last millennium. It emphasizes the two-way interaction between trade and geopolitics, and the importance of such interactions for world economic development.

Commodity Market Integration, 1500-2000

This paper provides a summary of what is known about trends in international commodity market integration during the second half of the second millennium. The range of goods which have been traded between continents since the Voyages of Discovery has steadily increased over time, and there has been substantial commodity market integration over the period, driven by technology in the 19th century and politics in the late 20th century. However, this trend towards greater market integration was not monotonic; it was periodically interrupted by shocks such as wars and world depressions, or by endogenous political responses to the distributional effects of globalization itself. In some periods politics has reinforced the effects of technology, while in other periods it has offset them. In several cases, severe shocks have had long-run effects on the international integration of commodity markets, as a result of politically induced hysteresis. Finally, we know remarkably little about international commodity market integration during the 20th century.

On the structure of the skin in Uranocentrodon (rhinesuchus) senekalensis, Van Hoepen

Main articleIn the famous collection of fossil remains of the labyrinthodont Uranocentrodon, housed since 1911 in the Transvaal Museum, the bony skin armour from the ventral surface of the body of at least six individuals has been preserved. In spite of this lavish quantity of material only a few notes on the osseous skin structure were included in van Hoepen' s (1915) description, and all later papers have passed it by almost completely.Non

Skin structure of small pareiasaurs. With comments on their taxonomy in the Cistecephalus Zone

Main articleThe Cistecephalus zone pareiasaurs all show skin armour. The features of this armour are described as found virtually complete in a small pareiasaur, identified here as an about half-grown Pareiasaurus serridens. Different in skin structure from this small pareiasaur is the dwarf-form, Nanoparia pricei. A few particulars have now been added to the known skin structure of this species. It is suggested that Cistecephalus zone pareiasaurs can be referred to 2 principal species: the one is Pareiasaurus serridens Owen, to which all the incomplete and variably grown specimens can be assigned such as the genus Propappus and some other species from the genera Pareiasaurus, Anthodon and Nanoparia. The other consists of the single specimen Nanoparia pricei. Further affinities are beyond existing evidence to settle.Non

On the scaloposaurid skull of Olivieria parringtoni, Brink with a note on the origin of hair

Main articleOlivieria parringtoni was described by Brink in 1965 as a new genus and species. It stands closest, among the scaloposaurids, to Ictidosuchops intermedius (Broom). In general shape and size, their skulls are virtually indistinguishable from one another, but Olivieria comes from the top of the Lystrosaurus-zone (early Triassic) while the type-locality of I. intermedius is the Cistecephalus-zone (Upper Permian). Differences in dentition and differences in detailed skull moulding had argued for the creation of the new genus.Non

Weight changes following lower limb arthroplasty : a prospective observational study

The aim of this study was to assess patterns of weight loss/gain following total hip or knee joint replacement. Four hundred and fifty primary lower limb arthroplasty patients, where the current surgery was the last limiting factor to improved mobility, were selected. Over a one year period 212 gained weight (mean 5.03kg), 92 remained static, and 146 lost weight. The median change was a weight gain of 0.50Kg (p=0.002). All patients had a significant improvement in Oxford outcome scores. Hip arthroplasty patients were statistically more likely to gain weight than knee arthroplasty patients. A successful arthroplasty, restoring a patient's mobility, does not necessarily lead to subsequent weight loss. The majority of patients put on weight with an overall net weight gain. No adverse effect on functional outcome was noted
