Scheduling workflow applications in grid environments is a great challenge, because it is an NP-complete problem. Many heuristic methods have been presented in the literature and most of them deal with a single workflow application at a time. In recent years, several heuristic methods have been proposed to deal with concurrent workflows or online workflows,(More)
In this paper, we focus on how to test for long-range dependence when the process may have a one-time mean change and how to estimate the change point when data may be long-range dependent. We rst analyzed why traditional long-memory tests have serious size distortions when data have short memory with breaks. In order to overcome this problem, a local(More)
This paper analyses the relationships that exist foreign direct investment (FDI), trade and similarity in relation to business cycle co-movements using a panel data set taken from 77 pairs of countries over the period 1988–2002. Most of the previous literature has overlooked the possible channels through which FDI might influence business cycle(More)
a r t i c l e i n f o a b s t r a c t Unlike the U.S. and most developed countries, Taiwan stock market has been widely documented to have no value premium. Prior studies on the value premium typically adopt a conventional approach proposed by Fama and French (1992), which suggests a buy-and-hold strategy with annual rebalancing. We argue that a(More)
