“To what extent does the multi-store model offer a reasonable account of human memory?” (12 Marks) The most influential multi-store model (or MSM) was proposed by Atkinson and Shiffrin in 1968. They found out that memory is divided into a series of stages. At each stage‚ the information is passed from one to another and is constraints in terms of capacity‚ duration and encoding. The first part of the MSM is the sensory memory. According to Baddeley‚ the sensory memory holds information for

Title: Using Compartmental models to predict hospital bed occupancy Abstract The use of acute care hospitals is a significant factor in the increasing cost of health care in many developed countries. The modelling of hospital beds should lead to better decision-making in relation to this expensive resource. The average length of stay is inappropriate for such modelling. Millard and others have shown that compartmental models can be used for bed modelling. These models are plausible and easily
