Sizing the government

Is there such a thing as an optimal government size? We investigate the so-called Armey curve, which claims an inverted U-shaped relationship between government size and economic performance, using non-parametric Data Envelopment Analysis (DEA). The DEA scores are linked to control variables, such as initial per capita income, openness, population density, urbanization, country size and family size. For 23 OECD-countries we estimate the country specific efficiency scores, which reveal the extent to which a country uses excess public resources to achieve the observed growth rate of GDP.

A sensitive and simple assay of saliva on stamps

Identification of saliva on stamps or envelope flaps remains yet a not widely studied problem. In most forensic laboratories it is seldom carried out, but this fact does not reduce the importance of the assay. Most authors consider amylase a sufficiently specific marker of the presence of saliva; really, the only other human body fluid that contains high amounts of this enzyme is the pancreatic juice (and therefore feces). Here we present a simple and sensitive assay for the determination of alpha-amylase that uses a commercially available and well-known substrate. It is hydrolyzed by amylase with the production of soluble blue fragments, that can be measured by photometry, obtaining objective results. The presented assay identifies 1 X 10(-6) diluted saliva or that present on 0.5 mg of a stamp; 16-year-old samples can also be identified. Intra-assay and day-to-day CV resulted in 10.8% and 13.7%, respectively. Owing to the high sensitivity of the test, handling samples or reagents can introduce contamination with saliva traces, giving false-positive results. Addition of EDTA 0.1 mol/l to the incubation mixture, lowering the sensitivity to 1 X 10(-3) diluted saliva, overcomes this problem.
