In this article, we consider the main challenges that impede us from realizing the great promise of computersupported cooperative work (CSCW). First, we discuss some of the key features that CSCW must provide in order to succeed with users. We follow this with a picture of the current state of the practice among CSCW users, and then we examine some technologies that hold promise for future appl...

A simple, highly sensitive, accurate and selective method for determination of trace amounts of Ni2+ in water samples. In this paper, Dioctylphthalate (DOP) was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-DOP sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a novel nano-Fe3O4-DOP-ED. Flame atomi...

The modified surface of Typha latifolia L. root (MSTL), as an alternative economical adsorbent, wasused for the removal of Ni (II) and Cd(II) ions from aqueous solutions. The effect of initial pH, initialconcentration of metal ion, and contact time was investigated in a batch system at room temperature.The kinetics data could be fitted well by pseudo-second-order model with correlation coeffici...

This paper approaches heterogeneity and heterogeneous technology as assets, rather than limitations, in the development of computer supported cooperative work. We demonstrate how heterogeneous technologies sustain teachers’ and students’ school work by presenting four different prototypes (the HyConExplorer, the eCell, the iGameFloor and the eBag) that complement one another because they offer ...

Computer Supported Cooperative Work (CSCW) research is the discipline that explores how to utilize computing and networking technologies to facilitate cooperation and collaboration among people. A variety of research has been conducted on CSCW architecture. However, how to ensure CSCW system effectiveness and efficiency on supporting collaboration remains a challenge. In this paper we present a...

This paper introduces Open Planning Process Panels (O-p3). These panels are based on explicit models of the planning process and axe used to coordinate the development and evaluation of multiple courses of action. We describe the generic ideas behind O-P3 technology, a general methodology for building O-P3 interfaces and two applications based on O-P3 technology the Air Campaign Planning Proces...

Different concentration (1–5 mol%) of Ni2+-doped FeS2 thin films were deposited by facile ECD technique. XRD pattern Ni2+ ion-doped cubic structure with the high intensity plane (2 0 0). HRSEM images show that undoped 1–2 mol% spherical-like morphology aggregated grains. 3 film was smaller size Electrochemical impedance analysis reveals minimum charge transfer resistance (69 Ω) is obtained for ...
