Opiate analysis in cadaveric blowfly larvae as an indicator of narcotic intoxication

Specimens of liver were collected from 40 cases in which the cause of death had been determined to be opiate intoxication. Rearings of Calliphora vicina larvae were then promoted on the decomposing liver. A control group of 10 decomposed liver specimens from non-opiate deaths was treated similarly. Analysis of larvae and liver for opiates (morphine) was conducted by radioimmunoassay. Good qualitative and quantitative correlation was observed in both the positive and negative groups. Regression analysis comparing the concentrations of opiates found in the larvae with those found in the liver in the positive group resulted in a correlation of r = 0.790.     

How do voters form positive economic beliefs? Evidence from the Survey of Americans and Economists on the Economy

Beliefs about normative economics appear to be primarily determined by sociotropic rather than egocentric variables. (Sears & Funk, 1990; Citrin & Green, 1990) Using the Survey of Americans and Economists on the Economy, the current paper finds that the same holds for positiveeconomic beliefs in most – but not all – cases. This hinges on whether a question is “causal” or “non-causal”: Causal beliefs depend on sociotropic variables, especially education and ideology; non-causal beliefs, in contrast, depend on egocentric variables, with income growth playing the leading role. This is consistent with a cognitive model where actors answer easier questions using personal experience, and harder ones with ``off-the-shelf" theories.
