Closed versus Open Innovation: Evolution or Combination?
The concept of open innovation has attracted great interest from the academic and industrial sectors alike. Despite the ongoing debate, we can see some lack of consistency of its principles. The purpose of this paper is to set out a conceptual reflection on the foundations of innovation and its process and discuss new proposals from the literature on open innovation. We question whether this co...
متن کاملOpen - Interval Graphs versus Closed - Interval Grap
A graph G = (V, E) is said to be represented by a family F of nonempty sets if there is a bijection f:V--*F such that uv ~ E if and only iff(u)Nf(v)q=~. It is proved that if G is a countable graph then G can be represented by open intervals on the real line if and only if G can be represented by closed intervals on the real line, however, this is no longer true when G is an uncountable graph. S...
متن کاملOpen Versus Closed: A Cautionary Tale
Workload generators may be classified as based on a closed system model, where new job arrivals are only triggered by job completions (followed by think time), or an open system model, where new jobs arrive independently of job completions. In general, system designers pay little attention to whether a workload generator is closed or open. Using a combination of implementation and simulation ex...
متن کاملClosed Reduction versus Open Reduction and Pin Fixation in Pediatric Type III Supracondylar Humeral Fractures
Background Supracondylar humeral fractures constitute about 60% and 13% of all pediatric elbow and pediatric skeletal fractures, respectively, with a peak incidence in the 5-7 years age group. The aim of this study was to evaluate and compare closed reduction with open reduction and pin fixation in type III supracondylar humeral fractures in children younger than...
متن کاملOpen versus Closed Endotracheal Suctioning in the Intensive Care Comparison of Closed Endotracheal Suction Versus
BACKGROUND: Ventilator-associated pneumonia (VAP), a frequent nosocomial infection in the intensive care, is associated with considerable morbidity. Endotracheal suctioning is routinely performed in mechanically ventilated patients to clear secretions. This study assessed if there were advantages of closed endotracheal suctioning (CES) over open endotracheal suctioning (OES) with respect to cli...
