Farkas' lemma for separable sublinear inequalities without qualifications

We show that Farkas’ lemma for linear inequality systems, established in 1902, continues to hold for separable sublinear inequality systems. As a consequence, we establish a qualification-free characterization of optimality for separable sublinear programming problems which include classes of robust linear programming problems.

Newton-Type Methods for Optimization Problems without Constraint Qualifications

We consider equality-constrained optimization problems, where a given solution may not satisfy any constraint qualification but satisfies the standard second-order sufficient condition for optimality. Based on local identification of the rank of the constraints degeneracy via the singular-value decomposition, we derive a modified primal-dual optimality system whose solution is locally unique, n...

Burnout and medical errors among American surgeons.

OBJECTIVE To evaluate the relationship between burnout and perceived major medical errors among American surgeons. BACKGROUND Despite efforts to improve patient safety, medical errors by physicians remain a common cause of morbidity and mortality. METHODS Members of the American College of Surgeons were sent an anonymous, cross-sectional survey in June 2008. The survey included self-assessm...

Recent medical technologies guidance relevant to surgeons

BRUCE CAMBELL Identifying procedures depends on clinicians notifying them when they first contemplate their use. That does not mean that they cannot start using the procedure: until NICE publishes guidance, the kind of ‘special arrangements’ recommended when evidence is uncertain is the rule: tell your hospital; tell your patients; and audit your results with special care. Reference 1. Health S...
