BACKGROUND Rift valley fever (RVF) is a re-emerging viral vector-borne disease with rapid global socio-economic impact. A large RVF outbreak occurred in Tanzania in 2007 and affected more than half of the regions with high (47 %) case fatality rate. Little is known about RVF and its dynamics. A cross sectional study was conducted to assess the knowledge, attitudes and practices regarding RVF in...

The term “flexible learning’ has been used by many institutions with regard to their methods of course delivery, particularly by those seeking to attract external students. In almost no cases is the use of the term justified, since the flexibility concerned relates only to certain very limited components of the learning process. This paper outlines the very real problems that are faced by insti...

abstract Information seeking is a complex task, and many models of the basic, individual seeking process have been proposed. Similarly, many tools now exist to support " sit-forward " information seeking by single users, where the solitary seeker interacts intensively with a search engine or classification scheme. However, in many situations, there is a clear interaction between social contexts...

This paper proposes a conceptual framework for creative information seeking drawing upon Weisberg’s argument that creativity exists in everyone, and mapping the creative process described in the holistic model of creativity to the information seeking activities identified in the behavioural model of information seeking.

The ways in which people seek and process information are fundamentally epistemic in nature.

This paper builds on recent calls for a shift towards activity-oriented perspectives on epistemic cognition and proposes a new theory of ‘epistemic commitments’. ...
