This paper investigates the mechanisms through which organizations develop dynamic capabilities, defined as routinized activities directed to the development and adaptation of operating routines, and reflects upon the role of (1) experience accumulation, (2) knowledge articulation and (3) knowledge codification processes in the evolution of dynamic, as well(More)
X-linked lymphoproliferative syndrome (XLP or Duncan disease) is characterized by extreme sensitivity to Epstein-Barr virus (EBV), resulting in a complex phenotype manifested by severe or fatal infectious mononucleosis, acquired hypogammaglobulinemia and malignant lymphoma. We have identified a gene, SH2D1A, that is mutated in XLP patients and encodes a(More)
A novel human gene, encoding a 188 amino acid polypeptide that contains a region similar to that of the epidermal growth factor, has been isolated. The gene, expressed in undifferentiated human and mouse teratocarcinoma cells, is shut off after inducing the cells to differentiate by treatment with retinoic acid. Introduction of the cDNA under the control of(More)
We have isolated a human and murine homologue of the Drosophila prune gene through dbEST searches. The gene is ubiquitously expressed in human adult tissues, while in mouse developing embryos a high level of expression is confined to the nervous system particularly in the dorsal root ganglia, cranial nerves, and neural retina. The gene is composed of eight(More)
The combination of an increase in the cAMP-phosphodiesterase activity of h-prune and its interaction with nm23-H1 have been shown to be key steps in the induction of cellular motility in breast cancer cells. Here we present the molecular mechanisms of this interaction. The region of the nm23-h-prune interaction lies between S120 and S125 of nm23, where(More)
Cross-species comparison is an effective tool used to identify genes and study their function in both normal and pathological conditions. We have applied the power of Drosophila genetics to the vast resource of human cDNAs represented in the expressed sequence tag (EST) database (dbEST) to identify novel human genes of high biological interest. Sixty-six(More)
Using a novel and comprehensive database on both US and EU private equity funds and their underlying investments, we study the drivers of private equity fund performance. First, we study whether their hedging properties are attractive enough to justify their low performance. We document that fund performance co-varies positively with both business cycles(More)
Using a novel and comprehensive database on the performance of US and EU private equity (PE) funds and their underlying investments, we find that the performance of PE funds is comparable to public market performance. We show how sensitive this result is to various assumptions and thereby reconcile existing divergent estimates. We find evidence consistent(More)
