Behavioral impairment as a consequence of PCB exposure beginning in utero has been reported in both humans and animals. The present study assessed the behavioral consequences of postnatal exposure to PCBs. Male monkeys (Macaca fascicularis) were dosed from birth to 20 weeks of age with 7.5 micrograms/kg/day of a PCB mixture representative of the PCBs(More)

There is evidence that polychlorinated biphenyl (PCB) congeners have differential effects on endpoints of neurotoxicity depending on their chemical structure: specifically, that ortho-substituted congeners are neurotoxic while coplanar (dioxin-like) congeners are relatively inactive in producing neurotoxic effects. This study extends research on the effects(More)
Of critical importance is the issue of whether exposure to a neurotoxic agent early in life or over a major portion of the lifespan can result in an age-related accelerated decline in neurological function. There is evidence in humans and animals that exposure to methylmercury may produce delayed neurotoxicity associated with aging. While lead is a(More)
A total of 80 menstruating rhesus monkeys (Macaca mulatta) were equally and randomly divided among groups receiving 0, 5, 20, 40, or 80 mu g of Aroclor 1254/kg body weight/day during a 6-year toxicological-reproduction study. During the first 3 years of the study, 4 of the treated monkeys became moribund and were euthanized; 3 had endometriosis. This(More)
Analytical examination of loss functions' families demonstrates that investors' utility maximisation is determined by their risk attitude. In computational settings, stock traders' fitness is assessed in response to a slow-step increase in the value of the risk aversion coefficient. The experiment rejects the claims that the accuracy of the forecast does(More)

In this chapter, I consider a design framework of a computational experiment in finance. The examination of statistics used for economic forecasts evaluation and profitability of investment decisions, based on those forecasts, reveals only weak relationships between them. The " degree of improvement over efficient prediction " combined with directional(More)
