Knowledge has been identified to be a significant organisational resource, which if used effectively can provide competitive advantage. A lot of emphasis is being put on how to identify, capture and share knowledge in todays organisations. It has been argued over the years that due to the fragmented nature of the construction industry and ad-hoc nature of the construction projects, capture and reuse of valuable knowledge gathered during a construction project pose a challenge. As a result critical mistakes are repeated on projects and construction professionals have to keep “reinventing the wheel”. Given the nature of construction projects, collaborative knowledge management seems to be the most appropriate solution to capture project based knowledge. Information and communication technologies offer a number of solutions to implement collaborative knowledge management solutions. This paper discusses a range of these solutions and presents a case study where a collaborative knowledge management solution is implemented across a multi functional construction company. The work presented in the case study was carried out while the first author was employed by the case study organisation. A social web application was implemented to solve a particular knowledge sharing problem within the organisations concrete pumping business. The new solution provided an effective and simple way to create knowledge by taking employees ideas through an iterative cycle of discussion.Article Outline1. Introduction2.

This study investigated the use of integrating use of mobile technologies, data services, and multimedia messaging systems to increase students use of mobile technologies and to develop environmental awareness. Data was collected using “usefulness of mobile learning systems” questionnaire from a sample consisting of 20 male and 21 female undergraduates enrolled in computer education and instructional technologies classes at the Near East University in North Cyprus. Students voluntarily participated in a six-week program using mobile telephones to transmit photographs of local environmental blights and to exchange pictures and observations. Participants learned ways to maintain clean environments and increased their awareness of environmental concerns. Responses on questionnaire differed significantly based upon gender and grade.Article Outline1. Introduction2. Theoretical foundation 2.1. Emergence of ML2.2.

The growing awareness on the opaque data management operated by many providers reveals that a privacy-aware service that protects user information from privacy leaks would be very attractive for a consistent portion of users. In order to meet this need we propose LotusNet, a framework for the development of social network services relying on a peer-to-peer paradigm which supports strong user authentication. We tackle the trade-off problem between security, privacy and services in distributed social networks by providing the users the possibility to tune their privacy settings through a very flexible and fine-grained access control system. Moreover, our architecture is provided with a powerful suite of high-level services that greatly facilitates custom application development and mash up.Article Outline1. Introduction2.

Lpez de Vergara, Sergio Lopez-BuedoClose preview| Related articles|Related reference work articles AbstractAbstract | Figures/TablesFigures/Tables | ReferencesReferences AbstractInternet traffic measurements collected during the busy hour constitute a key tool to evaluate the operation of networks under the heaviest-load case scenarios, and further provide a means to network dimensioning and capacity planning. In this light, this study provides a throughout analysis of the busy-hour traffic measurements of an extensive set of universities, regional networks and Internet exchange points collected from the Spanish Research and Education Network, RedIRIS. After showing that the traffic volumes observed in the busy hour over time can be modeled by a white Gaussian process, this work takes one step further and examines the influence of the networks intrinsic features, mainly population size and access link capacity, on the busy-hour traffic. Well-known statistical methodologies, such as ANOVA and ANCOVA, show that the network size in terms of number of users justifies most of the busy-hour traffic information. We further provide a linear-regression model that adjusts the amount of traffic that each network user contributes to the busy-hour traffic mean values, with a direct application to the problem of link capacity planning of IP networks.Article Outline1.

In fact, hard or equipment-based technologies support the two major strategic options, cost leadership and differentiation. At present, suppliers and governments, but not operators, drive research and development in the field. In the education sector, new specialised curricula incorporating pathways stemming from natural science are needed to equip future graduates with cutting edge skills for innovation at product, process and system levels. The research-teaching cycle can be strengthened by sharing degrees with departments of science and engineering across tertiary institutions.Article Outline1. Introduction2.

Although there is no general accepted definition of what constitutes a TI, we define it as comprising different kinds of public, semi-public and private centres and institutes of research and technology. Following a latecomer supply side technology-push rationale and using European structural funds, successive governments in Portugal invested in building a comprehensive TI-system. However, the development of such system overlooked the support needs of the enterprise sector. Hence, questions are now being raised as to whether current policies and structures of support to technology transfer and innovation are relevant and operating effectively. This, in turn, is generating a need to consider new policies oriented to stimulate demand-pull and the use of the capabilities already existent. This paper contributes to assess the outcomes of the efforts undertaken in Portugal to build an effective TI-system to support innovation and technology transfer and suggests new demand-oriented policies.Article Outline1.
