  • Messaging systems based on queuing include products such as Microsoft’s MSMQ [28]and IBM’s MQSeries [29]. The queuing model with their store-and-forward mechanisms come into play where the sender of the message expects someone to handle the message while imposing asynchronous communication and guaranteed delivery constraints. A widely used standard in messaging is the Message Passing Interface Standard (MPI) [21]. MPI is designed for high performance on both massively parallel machines and workstation clusters.

  • To avoid delays, consider using a third party to provide interim internal audit resources as needed. Through an outsourcing relationship, management and the audit committee are able to focus on hiring the right people while simultaneously delivering results. As staff are recruited and hired, the outsourcing relationship can be scaled to a cosourcing relationship or eliminated. In considering your longer-term staffing needs, remember that internal auditing is a dynamic, changing field that is no longer defined by who does the work.

  • The cattle-keeping Nilotes need little introduction here. This essay focuses on the Nuer, Dinka, Atuot, and Mandari of the Southern Sudan, concerning each of whom there is a substantial and easily accessible literature, while making passing reference to the closely related Anuak of the Southern Sudan and the more distantly related Pokot and Maasai of East Africa. The Nuer and Dinka in particular are well known to all students of anthropology.[Note 1] What does perhaps require some explanation is their being taken together as ‘the cattle-keeping Nilotes’.
