Effective interventions to reduce work-related exposures are available for many types of work-related diseases or injuries. However, knowledge of the impact of these interventions on injury or disease outcomes is scarce due to practical and methodological reasons. Study designs are considered for the evaluation of occupational health interventions on occupational disease or injury. Latency and ...

In Gambia, women groups are the core of developmental activities. The role of women in micro financing for poverty alleviation has long been recognized as vital approach to household welfare. Microfinance generally refers to the provision of financial services (e.g. savings, credit, insurance) to the poor especially women who normally do not have easy access to formal financial institutions. In...

The IEEE 802.15.4 has attracted time-critical applications in wireless sensor networks (WSNs) because of its beacon-enabled mode and guaranteed timeslots (GTSs). However, the GTS scheme's security still leave the 802.15.4 MAC vulnerable to attacks. Further, the existing techniques in the literature for securing 802.15.4 either focus on non beacon-enabled 802.15.4 or cannot defend against inside...

This paper argues that all current project risk management processes induce a restricted focus on the management of project uncertainty. In part this is because the term ‘risk’ encourages a threat perspective. In part this is because the term ‘risk’ has become associated with ‘events’ rather than more general sources of significant uncertainty. The paper discusses the reasons for this view, and...

Building on the observation that finger orientation is an inherent part of human's interaction in the real world, exploiting finger orientation for multitouch tabletop interaction would facilitate more natural interaction techniques. We motivate this by means of examples where the finger orientation improves or enriches interaction. Afterwards, we present a simple and fast approach to detect th...
