changes in fish faunal structure and diversity. Though catches of many species had declined by the 1960s due to overexploitation (Kudhongania et al., 1992), the dramatic increase in Nile perch in the 1980s in Lake Victoria was followed by a drastic decline in the populations of several indigenous species (Kaufman, 1992). Most notable has been the disappearance of over 50% of the endemic haploch...

A 12-years-old male child presented with polydactyly and syndactyly of hands, hypospadias, AND undescended testes. He was a known case of Tetrology of Fallot. One important differential in our case was Bardet-Biedl syndrome, but it was ruled out due to lack of evidence of central obesity, mental retardation and retinitis pigmentosa. At this time, there is no molecular testing available to disti...

The Kaufman Prize has been given by the Canadian Geriatrics Society for nearly 30 years, but few Society members are aware of who Kaufman was or why the Prize was named after him. They are equally unclear about the objectives established for the Prize and how successful it has been in achieving them. This paper reviews the history of the Kaufman Prize and the eponymous A.R. Kaufman. The origina...

The aim of this paper is to present a new proposal for Cluster Analysis based on a Greedy Randomized Adaptive Search Procedure (GRASP), with the objective of overcoming the convergence to a local solution. It uses a probabilistic greedy Kaufman initialization method for getting initial solutions and the K-Means algorithm as a local search algorithm. The new proposal will become a new initializa...

We present a new approach for Cluster Analysis based on a Greedy Randomized Adaptive Search Procedure (GRASP), with the objective of overcoming the convergence to a local solution. It uses a probabilistic greedy Kaufman initialization to get initial solutions and K-Means as a local search algorithm. The approach is a new initialization one for K-Means. Hence, we compare it with some typical ini...
