The current study aimed to find out English as a foreign language (EFL) students’ beliefs about the usefulness of corrective feedback in cooperative learning (CL) environment. This was qualitative research which narrative approach used. emphasises each student’s experiences with CL strategy. data were collected using interview questions instrument. researchers had close observation, prepared no...

Multi-agent optimization of object transport in known environments is addressed, in order to picture the main advantages regarding cooperative work in nontrivial problems like the one mentioned. Computational simulations are used to compare the effectiveness of non cooperative, partial cooperative and totally cooperative work; the total time needed to complete the tasks is used as the cost func...

Is it possible, and to what extent feasible, for link schedulers and buuer managers in multimedia networks with propagation delays to eeectively relieve congestion by means of feedback signalling? We show that a proactive, cooperative control algorithm for distributed resource scheduling and buuer management of multime-dia networks based on traac predictions of correlated input traac streams in...

We study the stability of voluntary cooperation in response to varying group growth rates. Using a laboratory public-good game, we construct a situation where increasing group size yields potential efficiency gains, but only with sustained cooperation. We then study the effect of exogenously varying growth rates on cooperation. Slow growth yields higher cooperation rates and welfare than fast g...

PURPOSE We examine the processes and document the calendar time required to activate phase II and III clinical trials by an oncology group: the Eastern Cooperative Oncology Group (ECOG). METHODS Setup steps were documented by (a) interviewing ECOG headquarters and statistical center staff, and committee chairs, (b) reviewing standard operating procedure manuals, and (c) inspecting study recor...

The evolutionary spread of cheater strategies can destabilize populations engaging in social cooperative behaviors, thus demonstrating that evolutionary changes can have profound implications for population dynamics. At the same time, the relative fitness of cooperative traits often depends upon population density, thus leading to the potential for bi-directional coupling between population den...

People are small group beings. Interacting with group members provides us with the opportunity to receive feedback, to discuss different ideas, and to get support for our endeavours. Groups generally learn faster, make fewer errors, recall better, make better decisions and are more productive than individuals working on their own. However, not all groups achieve high performance. Typically, gro...

The objective was to describe the utility of mixed methods to inform the development of an automated telephone intervention to improve patients' compliance with asthma medication. As part of intervention development for a larger trial, we conducted 15 focus groups (n = 53) to design and develop calls, and to identify factors influencing intervention acceptability and usefulness. We piloted four...

In recent years, cooperative communications are widely studied. Cooperative communications can obtain the space diversity as multiple-input multiple-output (MIMO) systems. In cooperative communications, the relay method is important as decode-and-forward (DF) and decode-amplify-forward (DAF). The multi-relay cooperative communications can improve the system performance. In the multi-relay coope...

E-learning at the workplace might be accomplished by synchronous cooperative learning sessions of small groups using net-based communication. This form of learning is suitable both for course-based e-learning as well as for knowledge transfer within the company. The small groups learn self-regulated, i.e. without the guidance of an instructor. However, the learning tasks are pre-defined and a s...
