The surface albedo feedback along with heat and moisture transport from the Equator to the Poles, are associated with polar amplification which is a well-established scientific fact. The present paper extends Brock and Xepapadeas (2017) to a non-cooperative framework with polar amplification, where regions decide emissions by maximizing own welfare. This can be regarded as a case of regional no...

Cooperation systems are intrinsically related with user interface systems. The design and implementation of a framework to support the construction of interactive and cooperative applications must be a consistent extension of the models and architectures of single user applications. The requirements for this extension include the management of the communication and coordination between users, t...

This paper first discusses cooperative learning and provides a rationale for its use in higher education. From the literature, six elements are identified that are considered essential to the success of cooperative learning: positive interdependence, face-to-face verbal interaction, individual accountability, social skills, group processing, and appropriate grouping. Three distinct approaches a...

L2 written corrective feedback has been investigated from different perspectives in SLA research (e.g. Ahmadian & Tajabadi, 2015; Bitchener & Knoch, 2010; Ferris, 2006). Taking the cognitive and sociocultural paradigms into account, the aims of the current study are twofold: Firstly, it attempts to find if corrective feedback is effective in improving the linguistic accuracy of L2 learners' ten...
