Stress Among Iranian Nurses in Critical Wards
BACKGROUND Stress has been recognized as a significant psychosocial and physiologic component in educational and practical processes. OBJECTIVES The purpose of present study was to survey stress among Iranian nurses in critical wards. PATIENTS AND METHODS In this cross-sectional study, 3643 anonymous questionnaires were disseminated among nurses in different hospitals in Tehran, Iran, by ut...
متن کاملMonodromy problem for the degenerate critical points
For the polynomial planar vector fields with a hyperbolic or nilpotent critical point at the origin, the monodromy problem has been solved, but for the strongly degenerate critical points this problem is still open. When the critical point is monodromic, the stability problem or the center- focus problem is an open problem too. In this paper we will consider the polynomial planar vector fields ...

متن کاملCrashes as Critical Points
We study a rational expectation model of bubbles and crashes. The model has two components: (1) our key assumption is that a crash may be caused by local self-reinforcing imitation between noise traders. If the tendency for noise traders to imitate their nearest neighbors increases up to a certain point called the “critical” point, all noise traders may place the same order (sell) at the same t...
متن کاملCritical Points 3
We consider manifolds M which admit smooth maps into a connected sum of S × S with only finitely many critical points, for n ∈ {2, 4, 8}, and compute the minimal number of critical points.
