Commonly, project managers and researchers agree that identifying risks is the most crucial step in project risk management. Hence, extant research provides various rankings of risk factors. In this paper, we rank the importance of risk factors based on an archive of project risk reports provided by project managers of a large software development company. In contrast to previous research that ...

Based on experimental and clinical studies performed by Machemer and coworkers and other researchers, intravitreal injection of triamcinolone acetonide (IVTA) has been used as an alternative for the treatment of several diseases of the retina and uvea, such as chronic cystoid macular edema, age-related macular degeneration, and retinal vascular occlusion. However, it is an invasive procedure, w...

The identification of specific characteristics that are associated with superstition may help to avoid the many risks (e.g. health anxiety, irrational behavior, emotional maladjustment) involved with extreme superstitious belief. This study examines two possible correlates of superstition: religiosity and locus of control. ANOVA suggest that levels of religiosity do not have a significant relat...

Uncontrollable stressors produce behavioral changes that do not occur if the organism can exercise behavioral control over the stressor. Previous studies suggest that the behavioral consequences of uncontrollable stress depend on hypersensitivity of serotonergic neurons in the dorsal raphe nucleus (DRN), but the mechanisms involved have not been determined. We used ex vivo single-unit recording...

It was 1974, and at the age of 25, I was working on the control of the cell cycle in fission yeast, one year into my post-doc with Murdoch Mitchison in Edinburgh. Hugely impressed by papers from Lee Hartwell, which described the isolation of cell division cycle (cdc) mutants in budding yeast, I started isolating cdcmutants in the rod-shaped fission yeast. These mutants could not divide but coul...

Given a controllable pair of matrices (A; B), the distance to the set of uncontrollable pairs is obtained as the minimum singular value of the set of augmented matrices A ? I; B] as varies over the complex plane. This study develops one dimensional and two dimensional algorithms to calculate or estimate the distance. The algorithms give guaranteed upper and lower bounds.
