ICT: An Emerging Paradigm for Success in Nigeria

It has been argued that for people to make successful employment inroads, they will need not only the know-how but also the psychological make-up to function in a turbulent job market that changes constantly in both boundaries and requirements. This dynamic might not be easily addressed through traditional career guidance and counseling. ICT has significant capacity and myriad capabilities to assist in this realm. It can provide a paradigmatic approach that is thematic and stochastic as well as unbiased, which might not be possible with the traditional approach. Here, the authors discuss such an approach with respect to the growing ICT field in Nigeria.

Item's Characterization for Model's Development in Information Retrieval System Evaluation

The purpose of this paper is to introduce the concept of Item’s Characterization (IC) in the search for usable measures for use at the user-centered level of the evaluation of IR systems. However, after identifying items for use to assess measures either to evaluate the system or propose them for use in the system’s evaluation as done in this study, it is appropriate to adequately characterize the items using the right method. The survey and Factor Analytic (FA) methods were used in this experiment. Results obtained from the experiment underscored the robustness of the concept of IC as well as the FA method used. It also showed that both IC and FA will impact on the process of IR system evaluation especially from user’s perspective. But a larger sample size and a parallel method of data collection are required for future study, in order to further confirm the model’s validity.
