A new species of the porcellanid genus Raphidopus Stimpson, 1858, is described on the basis of specimens from Penang and Kuala Selangor, Peninsular Malaysia. Raphidopus brevipes n. sp. is distinguished from its allied congeners, R. indicus Henderson, 1893 and R. johnsoni Ng Nakasone, 1994, by the proportionally narrower carapace and stouter ambulatory legs, as well as the different dentition on the cutting edge of the dactylus of the larger cheliped. Raphidopus johnsoni, previously known only by the holotype from Singapore, is now also recorded from Phuket (Thailand) and Java (Indonesia). Raphidopus indicus and R. johnsoni are rediagnosed on the basis of the respective type material and other specimens. A key to species of the genus Raphidopus is provided.
1.This paper records the treatment by a continuous intravenous quinine drip technique of fifteen cases of heavy P. falciparum infection in malnourished prisoners of war in a Singapore camp. These cases were selected from a series of approximately 1,000.2.The efficiency of the method, its simplicity, and the ease with which it can be combined with blood transfusion or the slow administration of thiamin are stressed.3.Recovery by this method of treatment is recorded of three cases with a peripheral intensity of infection higher than has hitherto been reported in Malaya with survival.4.The author is of the opinion that this is a safe and effective method for the treatment of pernicious falciparum infections.
This paper focuses on measuring risk due to extreme events going beyond the multivariate normal distribution of joint returns. The concept of tail dependence has been found useful as a tool to describe dependence between extreme data in finance. Specifically, we adopted a multivariate Copula-EGARCH approach in order to investigate the presence of conditional dependence between international financial markets. In addition, we proposed a mixed Clayton-Gumbel copula with estimators for measuring both, the upper and lower tail dependence. The results showed significant dependence for Singapore and Malaysia as well as for Singapore and US, while the dependence for Malaysia and US was relatively weak
