We study the problem of content delivery in two-user interference channels with altering topology, random available cache at receivers, and delayed channel knowledge transmitter. establish a new set outer-bounds on achievable rates when each receiver has access to fraction message intended for other receiver, transmitter is aware which part its own known unintended receiver. The reveal signific...

The study investigated whether two types of written corrective feedback, indirect focused corrective feedback and indirect unfocused corrective feedback, produced differential effects on the accurate use of grammatical forms by high intermediate EFL learners.

This paper examines whether self-controlled feedback schedules enhance learning, because they are more tailored to the performers' needs than externally controlled feedback schedules. Participants practiced a sequential timing task. One group of learners (self-control) was provided with feedback whenever they requested it, whereas another group (yoked) had no influence on the feedback schedule....

In this study we explore the role of information targeting and its effect on coordination in a multi-threshold public goods game. We consider four treatments, three in which we give feedback about other members‟ contributions to a subsample of group members and another treatment in which feedback is not provided at all. Our three information treatments vary in whom receives the information, whi...
