I use parametric and semiparametric methods to test for the order of integration in stock market indexes. The results, which are based on the EOE (Amsterdam), DAX (Frankfurt), Hang Seng (Hong Kong), FTSE100 (London), S&P500 (New York), CAC40 (Paris), Singapore All Shares, and the Japanese Nikkei, show that in almost all of the series the unit root hypothesis cannot be rejected. The Hang Seng an...

C hromosomes are shunted around the cell during mitosis to align at the metaphase plate and then segregate to the spindle poles. These movements are driven by dynamic microtubules, which polymerize and disassemble to pull the chromosomes into position. Chromosomes grab microtubules via their kinetochores, but how do they maintain their grip as the microtubules turn over? “It’s pretty amazing,” ...

We studied CMC (email and chat) and voice telephony, and compared them with fac...

Modern systems (e.g., service-oriented systems) embrace a distributed setting where a system consists of multiple autonomous parties. These individual parties have their own goals and achieve them by interacting with each other. Trust provides a basis for effective interaction, helping agents...
