It is well known that the pro forma performance of a sample of investment funds contains biases. These biases are documented in Brown, Goetzmann, Ibbotson and Ross (1992) using mutual funds as subjects. The organization structure of hedge funds, being private and often offshore vehicles, makes data collection a much more onerous task. This amplifies the impact of performance measurement biases....

Salvia divinorum (salvia) is an intense, short-acting hallucinogenic plant gaining popularity among adolescents in the United States. There has been little scientific documentation of salvia's effects. The popular video-sharing website YouTube has received literally thousands of video-posts of people using salvia. The objective of this study was to assess the effects of salvia use through syste...

We consider rewriting systems for unranked ordered terms, i.e. trees where the number of successors of a node is not determined by its label, and is not a priori bounded. The rewriting systems are defined such that variables in the rewrite rules can be substituted by hedges (sequences of terms) instead of just terms. Consequently, this notion of rewriting subsumes both standard term rewriting a...

To many, this is due to a paradigm shift in investment management and constitutes a modern financial revolution. However, to others, hedge funds are simply investment st...

H funds’ extensive use of derivatives, short selling, and leverage and their dynamic trading strategies create significant nonnormalities in their return distributions. Hence, the traditional performance measures fail to provide an accurate characterization of the relative strength of hedge fund portfolios. This paper uses the utility-based nonparametric and parametric performance measures to d...

The chemical composition of the essential oils of Salvia africana L., Salvia elegans Vahl, Salvia greggii A.
