Open Networked "i-Learning": Models and Cases of "Next-Gen" Learning

A brand new total interdisciplinary framework known as “i studying” integrates managerial association and know-how features sometimes called “technology stronger learning”. Open Networked "i Learning": types and situations of “Next-Gen” studying starts off its research with the real adjustments that experience lately happened in the administration, know-how and society fields.

Regionalism Among Developing Countries

Within the final decade, regionalism looks to have emerged as a huge new strength on the planet. This ebook places it in its old context. areas have emerged ahead of; few are previous simply because they both evolve into federal platforms or get a divorce. the present areas are much less dominant than their critics worry (they account for roughly a 3rd of global trade), yet suggest extra integration than an easy view that they're approximately liberalising exchange.
