Article history: Received 8 October 2011 Received in revised form 12 March 2012 Accepted 14 March 2012 Available online 23 March 2012 We present a multi-period trading model in the style of Kyle's (1985) inside trading model, by assuming that there are at least two insiders in the market with long-lived private information, under the requirement that each insider publicly disclose his stock tra...

Whether the information environment affects the cost of capital is a fundamental question in accounting and finance research. In this paper, we study the role of competition among informed investors on the pricing of information asymmetry and its implications for the pricing of information quality. Relying on theories on competition among informed investors and on the pricing of information asy...

Successful production and development of stable and adaptable genotypes only depend on the positive results achieved from the interaction between genotype and environment that consequently has a significant impact on breeding strategies. In this regard, we conducted an experiment to study genotypic differences of 16 lines durum wheat under both zinc sufficient and deficient stress during 2014-2...

In this paper, I show that the variance of Fama-French factors, the variance of the momentum factor, as well as the correlation between these factors, predict an important fraction of the timeseries variation in post-1990 aggregate stock market returns. This predictability is particularly strong from one month to one year, and it dominates that afforded by the variance risk premium and other po...

In most tissues and cells the opioid receptor-like (ORL1) receptor regulates effectors primarily through the pertussis toxin (PTX)-sensitive guanine nucleotide-binding regulatory proteins (G proteins) Gi/Go. Many Gi-coupled receptors possess additional capability to interact with one or more PTX-insensitive G proteins. Using the bg-induced stimulation of type 2 adenylyl cyclase as a readout, we...

Palmitoylated proteins contain a 16-carbon saturated fatty acyl group that is post-translationally attached by a labile thioester bond. These modified proteins are mainly membrane-bound; the lability of the thioester bond allows the process to be reversible, a unique property of this modification. We report here that the gene for G14, located in the class III region of the human MHC, encodes a ...

'Dwarf stature' maize variety offers promises to withstand unfavorable growth environments of Kharif season. But, for developing such variety, dwarf stature inbred lines must be available. Here, twenty-four F3 populations of white maize were evaluated though assessment of their genetic variability, heritability, and character association for selection of dwarf stature promising lines based on y...
