The escalation of commitment to a failing course of action is a well-known phenomenon in IT project management. Much work has been done in researching why managers continue to commit resources in the face of negative signals about the status of projects (Keil 1995; Keil 2000; Keil et al. 2000; Keil et al. 2003; Staw 1976). Information systems project failures typically exhibit ample warning sig...

A large variety of complex systems in ecology, climate science, biomedicine and engineering have been observed to exhibit tipping points, where the internal dynamical state of the system abruptly changes. For example, such critical transitions may result in the sudden change of ecological environments and climate conditions. Data and models suggest that some of these drastic events may be prece...

Mandibular canine impaction and transmigration have serious consequences for the patient, as removal of the tooth or teeth in question is often the only solution. The loss of one or both mandibular canines complicates orthodontic treatment. Early warning signs of mandibular canine ectopia are explored in this paper as well as how to assess the potential for displacement, impaction and/or transm...

See related article, pages 2864–2868. In this issue of Stroke, Kleindorfer and colleagues1 report on a chart review comparing the traditional 5 “sudden” warning signs of stroke and the FAST system. FAST is based on the Cincinnati Prehospital Stroke Scale (CPSS) and focuses on 3 symptoms: facial droop (F), arm drift (A) and speech problems (S), with “T” for “time” rounding out the acronym.

In Minnesota, 70 percent of all intersection-related fatal crashes for the period of 2006 to 2008 occurred at rural, through/stop intersections [1]. The Minnesota Department of Transportation identified improving the design and operation of intersections as a critical emphasis area in the Minnesota Comprehensive Highway Safety Plan [2]. At these intersections, sight restrictions caused by verti...

suicide rate in physicians has been reported to be higher than general population or other academics. previous studies found that 85-90% of people who commit suicide had been suffering from some type of psychiatric disorder. suicide prevention is the key element in lowering the numbers of physicians who destroy themselves and end their lives each year. it is needed to provide some educational p...
