In commercial software system development, software vendors often face the many difficulties to deal with large amount of requirements that enter the company every day. It is not possible to satisfy all the requirements in given constraint like time, cost, etc. hence there is a need to select the requirements that are more important. Requirements prioritization is a way that can play important ...

Signaling networks respond to diverse stimuli, but how the state of the signaling network is relayed to downstream cellular responses is unclear. We modeled how incremental activation of signaling molecules is transmitted to control apoptosis as a function of signal strength and dynamic range. A linear relationship between signal input and response output, with the dynamic range of signaling mo...

We develop a methodological approach to identify and prioritize psychosocial factors (stressors) requiring priority action to reduce stress levels. Data analysis was carried out on a random sample of 10 000 French employees who completed, during a routine interview with the occupational physician, a 25-item questionnaire about stress levels, as well as a questionnaire about 58 stressors grouped...

E-mail prioritization involves placing all of the ‘useful’ or ‘good’ unread e-mails at the top of the inbox, and all of the bad ones at the bottom. We use two cognitive decision models—a rational model, which considers all of the available information, and a fast and frugal model that uses one reason decision making— to prioritize e-mails. Experimental results, using real data obtained by unobt...
