Purpose
– Knowledge is a main resource of any organization. Knowledge management (KM) is identified by four processes: creating, capturing, distributing and sharing of knowledge. Technology can enable successful KM. The purpose of this paper is to propose a technology knowledge management (TKM) taxonomy, which lists popular electronic tools that can enhance KM processes and shows which tool can contribute to which processes.
Design/methodology/approach
– The taxonomy was developed by an extensive literature review of electronic KM tools and a three-year extensive analysis of different knowledge sources at the Jeddah Municipality (JM) in Saudi Arabia.
Findings
– The taxonomy can be used by practitioners developing an organizational KM system to guide them to choose a sufficient subset of tools that covers all four processes in order to ensure that no process is overlooked.
Research limitations/implications
– The result of using the TKM taxonomy and its effect on KM success is an interesting area for further research. However, the current value underlies in it offering practitioners a rough roadmap to an electronic KM system and aids in giving at least a starting point.
Practical implications
– The TKM taxonomy can be used by large scale organizations to guide in developing a KM system effectively and more efficiently. Furthermore, the JM KC is a good model for similar organizations to use, with all the tools explained in the paper.
Social implications
– The paper addresses some of the social elements related to successful KM in organizations. However, it is more technically targeted.
Originality/value
– Researchers have investigated either the holistic effect of IT on KM or described certain tools. The types of IT tools and their effect on KM have not been investigated. Furthermore, limited research addresses the design of effective KM systems and no tools exist to guide designers. The TKM taxonomy is a tool that can help KM practitioners and strategists to design effective KM systems efficiently, by guiding them in choosing tools that are suitable for certain KM processes. The paper also describes the JM Knowledge Center as a KMS model for organizations which addresses all four KM processes.
With the increasing emergence of group communication applications, and the need for more efficient usage of network resources, multicast techniques and protocols are becoming more vital in networks, and thus need to be given more attention.Multicasting refers to the ability to send information to several receivers at the same time. IP multicast and overlay multicast are two well known approaches that provide multicast services. Several limitations found in IP multicast are addressed in overlay multicast. However, implementation of multicast on MPLS still suffers from IP multicast limitations. This paper proposes a new protocol: the Overlay Multicast Protocol (OMP), in which the overlay approach is applied on MPLS networks to improve the scalability of multicasting. The detailed operations of OMP are explained and a simulation study is presented. The results show the improvement in performance when using OMP.
The use of variables in computer programming is one of the difficulties faced by students enrolled in introductory level programming classes. The Roles of Variables (ROV) concept associates small comprehensible roles to variables to help novice programmers comprehend how variables should be used. This paper describes an experiment that was conducted to test the effect of different engagement levels with ROV visualization on student programming skills. 91 Female students at King Abdul Aziz University (KAU), Jeddah, Saudi Arabia, participated in the experiment. The students were divided into three groups where they all had the ROV concept explained to them in a traditional classroom setting, but were given different visualization treatments during lab sessions. Results showed that while viewing the ROV visualization significantly improved student debugging skills, no other significant effects on student programming skills were reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
