appearing in this issue of Environmental Health Perspectives evaluate the relationship of perfluo-rooctanoate (PFOA) and perfluororooctane sulfonate (PFOS) with birth weight; they constitute the first rigorous epidemiologic studies to address this topic. The ubiquity of these chemicals in the environment and in humans and the growing concerns about potential health effects from such toxicants m...

Recent research indicates that when an event-monitoring paradigm is used, infants as young as 4.5 months of age demonstrate the ability to use featural information to individuate objects involved in occlusion events (Wilcox & Baillargeon, 1998a, Object individuation in infancy: The use of featural information in reasoning about occlusion events. Cognitive Psychology 37, 97±155; Wilcox & Baillar...

Carroll, Fuhrer and Wilcox (1994) studied the capacity of consumer sentiment to help explain the behaviour of consumption in the US. Their study was important for at least two reasons. Firstly, since household consumption accounts for about two thirds of US GDP, fluctuations in consumption may result in significant changes in the state of the macroeconomy. It is therefore important to develop m...

Forming Limit Diagrams are useful tools for evaluation of formability in the sheet metals. In this paper the effects of yield criteria on predictions of the right and left-hand sides of forming limit diagrams (FLDs) are investigated. In prediction of FLD, Hosford 1979, “Karafillis-Boyce” (K-B) and BBC2000 anisotropy yield functions have been applied. Whereas the prediction of FLD is based on th...
