Correlations on radioimmunoassay, fluorescence polarization immunoassay, and enzyme immunoassay of cannabis metabolites with gas chromatography/mass spectrometry analysis of 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid in urine specimens.

Results obtained from three commercial immunoassay kits, Abuscreen, TDx, and EMIT, commonly used for the initial test of urine cannabinoids (and metabolites) were correlated with the 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid (9-THC-COOH) concentration as determined by GC/MS. Correlation coefficients obtained based on 26 (out of 1359 total sample population) highly relevant samples, are 0.601 and 0.438 for Abuscreen and TDx. Correlation coefficients obtained from a parallel study on a different set of 47 (out of 5070 total sample population) highly relevant specimens are 0.658 and 0.575 for Abuscreen and Emit. The immunoassay concentration levels, that correspond to the commonly used 15 ng/ml GC/MS cutoff value for 9-THC-COOH, as calculated from the regression equations are 82 ng/ml and 75 ng/ml for TDx and EMIT and 120 ng/ml and 72 ng/ml for Abuscreen manufactured at two different time periods. The difference of these calculated corresponding concentrations provides quantitative evidence of the reagent specificity differences.     

Hazards of mattresses, beds and bedding in deaths of infants

Of 52 infants who had died suddenly and were referred to autopsy, nine had lain on adult water beds for the first time; five had died as a result of accidents; two had died on water beds; two were in beds with widely spaced slats; and one had died as a result of strangulation. Three deaths were due to overlying. Three other infants had been placed on sheepskin rugs for the first time and were found dead shortly thereafter. These infants ranged in age from 2 to 9 months, except for a severely mentally retarded nine-year-old with spastic paraplegia. We believe that a general warning should be issued concerning water beds and that soft bedding should not be used for infants. Infants should not be placed unattended or left to sleep on water beds; only beds recommended for infants should be used. Overlying of a young infant is most likely to occur on a water bed, or if the parent is obese or has consumed alcohol.     

A case of external beveling with an entrance gunshot wound to the skull made by a small caliber rifle bullet.

The external beveling caused by an entrance gunshot wound to the skull has not been completely explained, but the mechanism is probably a combination of several factors including the angle of shot, twisting force of a rotating bullet, blow-back effect, velocity, shape and size of the bullet, outspread of the kinetic energy from the bullet, and resistance of the skull.     

The Confidence Game: Roping in a Globalized World

This is the last in a series of five articles focusing on how Bernard Madoff’s confidence game (con game) worked. It examines the international money collecting activities by ropers for Bernard L. Madoff Investment Securities (BLMIS). Before globalization, Madoff’s con game brought him millions of dollars; after globalization, it began bringing him billions, making him remarkably successful until his run of luck was brought to a sudden halt by the worldwide economic downturn.     

The Effects of German Unification on the Federal Chancellor's Decision-Making

The purchase of Germany's Mannesmann AG by Britain's telecommunications holding company Vodafone in spring 2000 represented the first major cross-border hostile takeover in German corporate history. As spectacle, the story surrounding the fall of one of Germany's grandest industrial giants lays bare the underlying themes shaping the country's national discourse over how to build a new national consensus on the function of economic activity for the state, for society, and for the German citizen. As such, the Mannesmann-Vodafone saga contains a clear caesura between the Old and the New Economy in Germany. Of course the question remains which values and institutions do the Germans want to carry over from the old world into the new. And there the line between past and present becomes distinctly less discernible.     

Central Weakness and Provincial Autonomy: Observations on the Devolution Process in Russia

A specialist on regional politics and center-periphery relations in the Russian Federation examines the process of devolution of authority from Moscow to the regions in the 1990s. A discussion of the process by which federal treaties were negotiated is followed by an examination of types of de facto policy autonomy that have emerged at the regional level by default. Research sources include Russianlanguage documents and interviews with a range of central and regional officials. There follows a discussion of the impact on the devolution process of the institutional structure of the Russian state.
