land-use spatial allocation is a multi-objective collaborative spatial optimization methodfor rational use of the land use. based on global search capabilities and the information feedbackmechanism of ant colony optimization (aco), a land-use spatial allocation model (aco-la) isproposed. firstlyfirst, a construction graph is built for modeling the land-use spatial allocationproblem. secondlysec...

In a previous paper the CSCR domain was defined. Here this is taken to the next stage where the design of a particular Collaborative Research Environment to support Students and Supervisors ( CRESS) is considered. Following the CSCR structure this paper deals with an analysis of 13 collaborative working environments to determine a preliminary design for CRESS in order to discover the most appro...

using bibliographic records from the social science citation index, science citation index, and arts & humanities index, this paper tries to give a complete view of the characteristics of top ten iranian authors during 1990-2007 according to their authorship pattern. findings revealed that during 1990-2007 a total of 2650 articles were written by top ten iranian authors. findings showed that m....

We present an approach to create structured and shared workspaces supplying functionality to carry out collaborative activities for a range of learning tasks. A workspace is deened in terms of three interrelated components: group, task and colaboration; each one modelling respectively the relevant features for designing the structure and support for a collaborative learning activity. The system...

In order to improve the work efficiency, this paper introduces a collaborative office automation system, and describes main functional modules of system. It also demand analysis hierarchical system architecture design The has characteristics continuous stable operation, which improves efficiency team saves resources.

This study explored the effect of input vs. collaborative output tasks on Iranian EFL learners’ grammatical accuracy and their willingness to communicate (WTC). In so doing, the study utilized 3 input (i.e., textual enhancement, processing instruction, and discourse) and 3 collaborative output (i.e., dictogloss, reconstruction cloze task, and jigsaw) tasks and compared their effects on 5 Englis...

In this study, the effects of buyer-supplier relationships on company performance of suppliers in the Turkish automotive industry are analyzed. In the context of suppliers, it is found out that the relationships in the Turkish automotive industry have a three-phase structure such as competitive, transition period, and collaborative periods. The performance of the companies demonstrating collabo...

A learning object repository (or LOR) is presented as a mechanism which facilitates the organisation and reuse of collaborative learning scenarios, using metadata and ontologies. The main design concern here is making it easy for authors and learners to work with the LOR while creating or using learning environments. Three views of the repository are proposed: a reusable storage structure, a dy...

The CoAKTinG project aims to advance the state of the art in collaborative mediated spaces for distributed e-Science. The project is integrating several knowledge based and hypertext tools into existing collaborative environments, and through use of a shared ontology to exchange structure, promotes enhanced process tracking and navigation of resources before, after, and while a meeting occurs. ...

People working with ad-hoc collaboration tools suffer from information overload and information scatter. Our five-month study of project managers found their work comprised of fragmented activities scattering in task, people and application. However, these loosely coupled collaborative activities were implicitly organized by hierarchical activity threads through intrusion and digression, and ge...
