The Nine Deadly sins of Project Planning

Seven deadly sins of environmental epidemiology and the virtues of precaution.

The potentials for error in planning, conducting, reporting, and utilizing epidemiologic results can be considered in terms of the traditional 7 deadly sins. To counter these sins, epidemiologic virtues should be inspired by the precautionary principle. The remedies emphasize acknowledgment and exploration of the impact of uncertainties, weight-of-the-evidence assessments that consider what cou...

A New Multi-objective Model for Multi-mode Project Planning with Risk

The purpose of this problem is to choose a set of project activities for crashing, in a way that the expected project time, cost and risk are minimized and the expected quality is maximized. In this problem, each project activity can be performed with a specific executive mode. Each executive mode is characterized with four measures, namely the expected time, cost, quality and risk. In this pap...

The UNSIN project: exploring the molecular physiology of sins.

Although active learning works, promoting it in large undergraduate science classes is difficult. Here, three students (F. Naji, L. Salci, and G. Hoit) join their teacher (P. K. Rangachari) in describing one such attempt. Two cohorts in a first-year undergraduate biology course explored the molecular underpinnings of human misbehavior. Students were divided into 18 groups and randomly allotted ...
