Chloroquine concentrations in blood and tissues were examined in overdose and non-overdose cases to determine appropriate ranges for interpretation. Twenty-nine literature overdose cases and 8 non-overdose literature cases were compared with this laboratory's findings. The results indicate significant postmortem redistribution of chloroquine. Combining this laboratory's results and the literature results indicates that using a liver concentration of 150 mg/kg as a cutoff between overdose and non-overdose concentrations properly identified 30 of the 34 published cases containing liver chloroquine and 19 of the 20 presented cases. 相似文献

Using a neoclassical growth model augmented with human capital, we investigate the impact of the presence of state owned enterprises
(SOEs) on macroeconomic performance in China, using provincial data from 1990 to 2004. We estimate a macroeconomic model with
panel methods to explain changes in labor productivity resulting from standard influences as well as presence of the SOE sector
measured in five different ways. While controlling for growth in the labor force and physical capital, government size, exposure
to trade and change in economic structure, we conclude that the relative share of the SOE sector has no significant influence
on macroeconomic performance in China during our sample period. 相似文献

By using a dynamic stochastic optimization model, this paper shows that the existence of punishment does not necessarily deter
extramarital affairs. This study may help to explain why extramarital affairs are a common phenomenon in most societies even
though punishment exists. This study also has an implication for family laws: extramarital affairs can be effectively reduced
if the legal punishment scheme is designed in the way that makes the adulterer’s expected loss increase with the level of
adultery at an increasing or constant rate.

Many mechanisms (such as auctions) efficiently allocate an asset to the firm which values it most highly. But sometimes the asset’s owner may benefit from the transfer only if the asset is not too valuable to potential buyers. In this setting, we examine the efficiency of mechanisms when the potential buyers have private information about the asset’s value. We show that rent seeking, and lobbying, rather than merely wasting resources, can lead to allocations which are close to efficient. 相似文献
