Research indicates that knowledge sharing promotes teacher professional learning opportunities and development. However, it is yet to be known what motivates teachers in rural schools their as they may face more challenges than urban areas when sharing. This study examined factors explaining teachers' behavior regarding digital educational resources, both within outside school, posited by combi...

Modern computer architectures, particularly multicore systems, include shared hardware resources such as caches and interconnects that introduce timing-interference channels. Unmanaged access to such resources can adversely affect the execution time of other tasks, and lead to unpredictable execution times and associated analysis pessimism that can entirely negate the benefits of a multicore pr...

since we cannot manage what we cannot control, and we cannot control what we do not measure, the measurement of knowledge management (km) effectiveness is a very important issue. this study aims at developing a methodology to evaluate the km effectiveness under fuzziness in research organizations. in order to develop such a methodology and to define measures of km effectiveness, first the relev...

Sharing IT resources within and among organizations is an attractive value proposition in terms of efficiency and flexibility, but despite this, commercial practice is limited. In contrast, financial and commodity markets have proved very successful at dynamic allocation of different resource types to many different organizations. Thus to understand how the potential benefits of sharing IT reso...

Cloud computing is the latest technology that involves distributed computation over the Internet. It meets the needs of users through sharing resources and using virtual technology. The workflow user applications refer to a set of tasks to be processed within the cloud environment. Scheduling algorithms have a lot to do with the efficiency of cloud computing environments through selection of su...

We study a political competition between two groups, where the winner has the decision rights to allocate resources, like political parties deciding on sharing of patronage goods. What factors determine how resources are shared? We highlight an important force that affects distribution of resources, namely the ability to move between groups. In many contexts, group sizes are determined endogeno...

In software systems, individual components interact not only through explicit function invocations, but also through implicit resource sharing. The use of shared resources significantly influences the duration of the invoked functions. For resources that are heavily shared, capturing this influence can lead to performance models that have a large number of elements and a large number of depende...
