This study examines task-based, synchronous computer-mediated communication (CMC) among intermediate-level learners of English. The research specifically explores (a) whether learners engage in negotiated interaction when they encounter new lexical items, (b) whether task type has an effect on the amount of negotiation that transpires, and (c) how this computer-mediated negotiation compares to ...

People are emotional, and machines are not. That constrains their communication, and defines a key challenge for the information sciences. Different groups have addressed it from different angles, trying to develop methods of detecting emotion, agents that convey emotion, systems that predict behaviour in emotional circumstances, and so on. Progress has been limited. The new network of excellen...

In this paper, we present a novel encryptionless algorithm to enhance security in transmission of data in networks. The algorithm uses an intuitively simple idea of a “jigsaw puzzle” to break the transformed data into multiple parts where these parts form the pieces of the puzzle. Then these parts are packaged into packets and sent to the receiver. A secure and efficient mechanism is provided t...
