Despite a significant increase in whistle-blowing practices in work organizations, we know little about what differentiates whistle-blowers from those who observe a wrongdoing but chose not to report it. In this review article, we first highlight the arenas in which research on whistle-blowing has produced inconsistent results and those in which the findings have been consistent. Second, we pro...

a prior history of healthy lifestyle may be misleading when we consider associated risk factors for developing a serious and debilitating condition such as multiple sclerosis under extreme stress. the author reports a case of a woman who lived a healthy life and yet experienced an unexpected event leading to the diagnosis of multiple sclerosis. the patient’s condition was predominantly provoked...

carpal tunnel syndrome is known as an industrial new epidemic. in many of jobs, the same motions of hand are repeated thousands of times a day.  each day the number of people with the syndrome is increasing. clerks, workers in food preparation and packaging, and secretaries of large supermarkets have a high risk for suffering from this syndrome. in fact, all people who flex and extend their wri...

Recurrent ventricular tachycardia (VT) in the setting of left (LV) aneurysm and scar can be challenging to control, particularly cases with mid-myocardial or epicardial circuits. Strategies for substrate modification VT LV include endocardial ablation as well surgical resection refractory catheter ablation. Here, we present a case apical that was medical therapy recurred after ablations. Our pa...

Faced with a complicated task, some initial planning can significantly increase the likelihood of success and increase efficiency, but planning for too long before starting to act can reduce efficiency. This paper explores the question of when to begin acting for a resource bounded agent. Limitations of an idealized algorithm suggested in the literature are presented and illustrated in the cont...

Automated domain factoring, and planning methods that utilize them, have long been of interest to planning researchers. Recent work in this area yielded new theoretical insight and algorithms, but left many questions open: How to decompose a domain into factors? How to work with these factors? And whether and when decomposition-based methods are useful? This paper provides theoretical analysis ...
