Interactive Data Language (IDL) is an arrayoriented data analysis and visualization application, which is widely used in research, commerce, and education. It is meaningful to make end user IDL applications collaborative on events between computers over networks, using a common message broker as the underlying communication system, and deploy them in Peer-to-Peer Grid architecture. In order to ...

Abstract This study was intended to compare collaborative and individual task planning effects on Iranian EFL learners’ writing performance. Therefore, a group of 90 upper intermediate EFL learners were placed in three groups of Collaborative Task planning, Individual Task planning, and Control. In the experimental groups, participants were asked to do task planning collaboratively and individu...

This paper introduces a framework for carrier dynamic collaboration. In particular it proposes and analyzes dynamic collaborative mechanisms that are incentive compatible. The dynamic collaborative environment is characterized by a set of carriers that have a proprietary set of customers that generate a stream of random demands over time. The proposed collaborative mechanism is such that upon e...

This article aims at presenting a three-dimensional framework dedicated to structure the domain of crisis management. The approach is based on a formalized vision of crisis (the danger / risk / consequence chain) that is used to define the what, when and where of crisis management. These three basic questions allow describing the management, time (life cycle) and localization dimensions of cris...

This study explores the emerging phenomenon of collaborative online shopping by comparing three navigation support designs: separate navigation with location cue, split screen navigation, and tightly-bonded shared navigation. The impacts of the three navigation support designs on collaborative customers’ actual and perceived shared understanding were investigated in a laboratory experiment. The...

The present study aims to investigate the relative effectiveness of different types of pragmatic instruction including two collaborative translation tasks and two structured input tasks with and without explicit pragmatic instruction on the production of apologetic utterances by low-intermediate EFL learners. One hundred and fifty university students in four experimental groups and one control ...

Cloud based web-applications are quickly becoming common in modern society. A new class of such applications, collaborative cloud applications, are gaining in popularity as they greatly improve remote collaboration. Most of these applications use a log structure as a coordination mechanism for shared application state. Such structures typically store the entire application state as well as delt...

Polycrystalline films are used in a wide array of microand nano-scale devices, for electronic, mechanical, magnetic, photonic and chemical functions. Increasingly, the properties, performance, and reliability of films in these systems depend on nano-scale structure. In collaborative research with a number of SMA Fellows, Associates, and students, our group is carrying out research focused on pr...

The purpose of this study was to examine the relationships of the students’ perceived levels of collaborative learning, social presence and overall satisfaction in a blended learning environment. This research studied the relationship of these three variables and identified critical factors related to them. The participants were 48 graduate students who took a blended-format course in health ed...
