Gordon Tullock’s The Organization of Inquiry: A critical appraisal

The major themes of Gordon Tullock’s 1996 book The Organization of Inquiry are identified. Tullock’s treatment of the philosophy of science is criticized, as is his explanation for the backwardness of the social sciences relative to the natural sciences. The paper closes with a listing of some of Tullock’s proposals for the reform of science.     

Analysis of N,N-diethyl-m-toluamide (DEET) in human postmortem specimens

N,N-diethyl-m-toluamide (DEET) levels in postmortem specimens of stomach and contents, blood, liver, and urine are reported following ingestion of the compound. DEET was analyzed by gas chromatography with an OV-101 column and a nitrogen phosphorus detector. The presence of the compound in the four postmortem specimens was confirmed by mass spectrometry.     

Group-specific component: a review of the isoelectric focusing methods and auxiliary methods available for the separation of its phenotypes

This review compares the major isoelectric focusing methods that have been published for the separation of group-specific component (Gc) phenotypes since 1978. The various parameters of gel composition, size, electrical and running conditions and sample application points are listed. More current auxiliary methods are also listed. These relate to the extraction of Gc from bloodstains and its identification after isoelectric focusing. Protocols are then recommended for the forensic analysis of Gc phenotypes.     

Polymorphism of seminal gamma-glutamyl transpeptidase

Electrophoretic analysis of seminal gamma-glutamyl transpeptidase (GGT) activity of 147 unrelated Japanese males revealed three types of band patterns. An anodal single band, a cathodal single band and heterozygous double bands termed 1, 2 and 2-1, respectively, were commonly identified in the samples. The frequencies of the three types were 1 = 0.22, 2 = 0.33 and 2-1 = 0.44. Seminal stains kept for more than 6 months revealed distinguishable band patterns as well as fresh samples.
