Is knowledge management losing ground? Developments among Icelandic SMEs

This paper presents findings from a survey on knowledge management (KM) in small and medium-sized firms (SMEs) in Iceland conducted in 2007 and was a follow-up of a similar survey from 2004. The paper analyses whether the extent, strategy and effects of KM in SMEs in Iceland has changed in the period. The main conclusion is that KM is not losing ground among SMEs in Iceland. Identical numbers of firms used KM in 2004 and 2007, and slightly more firms were examining the need in 2007 than 3 years earlier. It is, however, of great concern that many more firms have no KM strategy in 2007 than 2004. More managers in SMEs need to consider the strengths and weakness of KM, and to implement a formal KM strategy. Only 24% of Icelandic firms have a KM programme in place, and most of them have invested in simple information and communication technologies. The most common way of sharing tacit knowledge in Icelandic firms is encouraging face-to-face communication. The surveys indicate that benefits of KM programmes are quite positive even in SMEs. Accordingly, the research findings indicate that KM could improve organisational and managerial as well as financial aspects of SMEs. This research was carried out in only one country, and is based on a questionnaire. Its results should therefore be interpreted with care.     

Muscle activity in sprinting: a review

The use of electromyography (EMG) is widely recognised as a valuable tool for enhancing the understanding of performance drivers and potential injury risk in sprinting. The timings of muscle activations relative to running gait cycle phases and the technology used to obtain muscle activation data during sprinting are of particular interest to scientists and coaches. This review examined the main muscles being analysed by surface EMG (sEMG), their activations and timing, and the technologies used to gather sEMG during sprinting. Electronic databases were searched using ‘Electromyography’ OR ‘EMG’ AND ‘running’ OR ‘sprinting’. Based on inclusion criteria, 18 articles were selected for review. While sEMG is widely used in biomechanics, relatively few studies have used sEMG in sprinting due to system constraints. The results demonstrated a focus on the leg muscles, with over 70% of the muscles analysed in the upper leg. This is consistent with the use of tethered and data logging EMG systems and many sprints being performed on treadmills. Through the recent advances in wireless EMG technology, an increase in the studies on high velocity movements such as sprinting is expected and this should allow practitioners to perform the analysis in an ecologically valid environment.     

Do You Know What It Means to Miss New Orleans? Internet Communication, Geographic Community, and Social Capital in Crisis

This study investigated Internet communication and use in a crisis situation, Hurricane Katrina, to explore the role of the Internet in supporting or diminishing geographically-based community during a crisis. The researchers conducted an online survey of Internet users (n=1192) from the dispersed metropolitan New Orleans area. The survey focused on amount, type, function, and importance of Internet use to creating and maintaining social capital, supporting geographically-based communities, activating social networks, reducing uncertainty, and achieving both expressive and instrumental communication goals. The results indicated that Internet users in a crisis situation went online to seek interactive fora specific to their neighborhoods and to activate weak ties in their social networks. They engaged in more uncertainty reduction behavior when experiencing higher degrees of damage. They turned to the Internet in place of other media as a result of disruptions caused by the crisis. Women valued online expressive communication more than men did. The findings suggest that social capital theorists would benefit from a communication perspective on the Internet. The study also led to the formation of suggestions for emergency preparedness agencies, shelter providers, crisis victims, and online news providers that can improve emergency response.     

Upper secondary and vocational level teachers at social software

This study focuses on upper secondary and vocational level teachers as users of social software i.e. what software they use during their leisure and work and for what purposes they use software in teaching. The study is theorised within a technological pedagogical content knowledge framework, the emphasis is especially on technological knowledge and technological pedagogical knowledge. Four hundred thirty seven teachers were surveyed using an online questionnaire with Likert scaled statements and open-ended questions. Results suggest that the number of different types of social software actively used for teaching is small and that the potential of social software as a tool for supporting collaborative learning has not yet been realised. Discussion of the results is framed in the context of teachers’ developing technological pedagogical content knowledge.
