Improving the Asmussen-kroese Type Simulation Estimators Improving the Asmussen-kroese Type Simulation Estimators *

Asmussen-Kroese [1] Monte Carlo estimators of P (Sn > u) and P (SN > u) are known to work well in rare event settings when Sn is the sum of n i.i.d. heavy-tailed random variables, and N is a non-negative integer-valued random variable independent of the Xi. In this paper we show how to improve the Asmussen-Kroese estimators of both probabilities when the Xi are non-negative. We also apply our i...

Marjorie Taylor: Children's imaginary companions

Sergei Nirenburg Marjorie McShane Stephen

In this paper, we briefly and informally illustrate, using a few annotated examples, the static and dynamic knowledge resources of ontological semantics. We then present the main motivations and desiderata of our approach and then discuss issues related to making ontological-semantic applications feasible through the judicious stepwise enhancement of static and dynamic knowledge sources while a...

Pancreatic Transplantation, the 8th Marjorie Budd Lecture

Though the introduction of insulin in 1922 immediately transformed the management of diabetes, allowing diabetics to survive with their disease, the microvascular complications of the disease became increasingly evident with time. Thus insulin-dependent or type 1 diabetes is the fifth major cause of renal failure, the major cause of blindness, and coronary heart disease is a major cause of deat...

Marjorie Harness Goodwin and Charles Goodwin

The children whose conversations are examined in this chapter are working-class black preadolescent girls and boys from Philadelphia, ages 4-14, whom I (Marjorie Harness Goodwin)' audiotaped for a year and a half as they went about their everday activities while playing on the street. The "Maple Street\group," as the children will be referred to, includes forty-four friends living within a bloc...
