The is expectation gap: industry expectations versus academic preparation

Abstract: Recent changes in information systems technologies, applications, and personnel require us to reconsider the skills for tomorrow's IS professionals. This study uses data from four groups-IS managers, end-user managers, IS consultants, and IS professors-to identify the key skills and knowledge that will be required of future IS professionals. These requirements were then compared with current IS academic programs. The results reveal that despite a shared vision of the future IS professional, there is an "expectation gap" between industry needs and academic preparation. Industry and universities must work together to close this gap. Universities need to place more emphasis on the integration of technologies, applications, data, and business functions and less on traditional and formal system development. Firms need to send consistent messages to universities about their expectations while recognizing that the mission of university business programs is career education, not job training.

Comparisons of three probability formulae for parentage exclusion

Abstract: Three general formulae calibrate the average capability of marker systems to dispute falsely reported pedigree records in uniparous species. The most familiar exclusion formula applies to paternity, although the same formula applies equally to maternity. Another formula faults the relationship of a single offspring with its putative parent; for example, where the genotype of the other parent is not available. The remaining formulae excludes both of the falsely recorded parents of a substituted offspring. Simplified forms of the three general formulae facilitate the calculation of maximal average exclusion values over a range of hypothetical markers. Allele frequency data on eight marker systems in horses provide practical examples. The exclusion values of the three formulae are compared.

A giant outburst two years before the core-collapse of a massive star

Abstract: The death of massive stars produces a variety of supernovae, which are linked to the structure of the exploding stars. The detection of several precursor stars of type II supernovae has been reported (see, for example, ref. 3), but we do not yet have direct information on the progenitors of the hydrogen-deficient type Ib and Ic supernovae. Here we report that the peculiar type Ib supernova SN 2006jc is spatially coincident with a bright optical transient that occurred in 2004. Spectroscopic and photometric monitoring of the supernova leads us to suggest that the progenitor was a carbon-oxygen Wolf-Rayet star embedded within a helium-rich circumstellar medium. There are different possible explanations for this pre-explosion transient. It appears similar to the giant outbursts of luminous blue variable stars (LBVs) of 60-100 solar masses, but the progenitor of SN 2006jc was helium- and hydrogen-deficient (unlike LBVs). An LBV-like outburst of a Wolf-Rayet star could be invoked, but this would be the first observational evidence of such a phenomenon. Alternatively, a massive binary system composed of an LBV that erupted in 2004, and a Wolf-Rayet star exploding as SN 2006jc, could explain the observations.
