In vivo bone lead measurements with 109Cd-based K-shell X-ray fluorescence (XRF) have been used to assess long-term lead exposure in adults. Tibia lead levels were measured in 210 children (106 boys, 104 girls) of 11-12(1/2) years of age in a lead smelter town and in a control (nonexposed) town. Tibia lead levels, methodological uncertainties, and models of some of the factors influencing them ...

Further, even though it is intellectually accepted that we have methodological means to combat these factors and provide benefits during the evolutionary process, development managers still choose short term goals over these long term benefits. Given a choice between getting a system out as early as possible and doing a proper design that will evolve gracefully, the first is invariably chosen a...

Using a number of short-term maturities and monthly data, 1984-1997, we provide a number of tests of the expectations hypothesis (EH) of the term structure. The paper draws on cointegration techniques and the methodological approach of Campbell and Shiller (1987,1991). On balance our results lend support to the EH and are broadly consistent with recent findings for the UK, but are in sharp cont...

Sexual selection theory and parental investment theory suggest that partner physical attractiveness should more strongly affect men's relationship outcomes than women's relationship outcomes. Nevertheless, the contextual nature of this prediction makes serious methodological demands on studies designed to evaluate it. Given these theories suggest that men value observable aspects of partner att...

Today a convergence between the fields of anthropology and economics has re-emerged after decades during which the dictates of methodological individualism, as strikingly elucidated by Kenneth Arrow, had seriously limited and hampered effective scholarship in studies of economic and social development in developing countries. A new generation of development economists represented by Spolaori an...
