the present study investigated efl teachers’ beliefs about oral corrective feedback (cf), their cf-provision practices across elementary and intermediate levels, and their beliefs-practices correspondence. to this end, the researchers conducted a semi-structured interview with the teachers and went on an overall forty-hour observation of their classrooms across both levels. the findings reveale...

Several bacterial pathogens are targeted by macroautophagy (referred to as autophagy hereafter), and autophagy is widely recognized as an important antibacterial defence mechanism [1]. On the other hand, new work has shown that some bacterial pathogens have mechanisms to avoid or exploit the autophagy machinery for intracellular survival [2–4]. Strikingly, the host cytoskeleton plays a crucial ...

Scheduling product batches in pipelines is a very complex task with many constraints to be considered. Several papers have been published on the subject during the last decade. Most of them are based on large-size MILP discrete time scheduling models whose computational efficiency greatly diminishes for rather long time horizons. By introducing an MILP continuous representation in both time and...

W e consider multimachine scheduling problems with earliness and tardiness costs. We first analyze problems in which the cost of a job is given by a general nondecreasing, convex function F of the absolute deviation of its completion time from a (common) unrestrictive duedate, and the objective is to minimize the sum of the costs incurred for all N jobs. (A special case to which considerable at...
