This paper tests for the impact of survivorship bias by building on the work of Cubbin, Eidne, Firer and Gilbert (2006), and Bailey and Gilbert (2007). The former paper confirmed the existence of mean reversion of relative returns on the JSE, because portfolios of shares with high Price to Earnings (P/E) ratios (being those which had tended to outperform recently) underperformed significantly o...

austenitic stainless steels are extensively used in various applications requiring good corrosion resistance and formability. in the current study, the formation of nano/ ultrafine grained austenitic microstructure in a microalloyed aisi 304l stainless steel was investigated by the advanced thermomechanical process of reversion of strain-induced martensite. for this purpose, samples were subjec...

In this paper we propose a jump-diffusion type model which recovers the main characteristics of electricity spot price dynamics in the Nordic market, including seasonality, mean-reversion and spiky behavior. We show how the calibration of the market price of risk to actively traded futures contracts allows for efficient valuation of Nord Pool's Asian-style options written on the spot electricit...

The predictability of funds returns has always been a hot topic in academic circles. Relevant scholars have carried out lot empirical studies and found that prices tend to revert the mean after rising falling for while. In view fund long-term return forecast problem, this study investigates performances three underlying assets, i.e ., ZhongOu Medical And Health Hybrid A, Fullgoal China Securiti...

We assess the progress made by the profession in understanding real exchange rate behavior through a selective and critical, but nonetheless expository, review of the literature. Our reading of the literature leads us to the main conclusions that purchasing power parity might be viewed as a valid long-run international parity condition when applied to bilateral exchange rates obtaining among ma...

backgrounds: evidence is accumulating to support disruption of tissue architecture as a powerful event in tumor formation. for the past four decades, intensive cancer research with the premise of “cancer as a cell based-disease” focused on finding oncogenes or tumor suppressor genes. however, the role of the tissue architecture was neglected. three dimensional (3d) cell cultures which can recap...
