The effect of conditions of putrefaction on species determination in human and animal teeth

Tooth fragments freshly extracted from humans and rats were stored at either 4 degrees C or room temperature in dry or humid conditions for periods ranging from 1 to 6 months. The fragments were reduced to powder and antigens were extracted. Comparison of these samples was carried out using Counter Current Electrophoresis. Extracted sera were tested against known specific antisera and resultant precipitin reactions stained for examination. Correct species identification was possible both from desiccated and humid fragments but there was species variation in the sensitivity of the method. All the extracts from human teeth were positive against human antisera. In the rat some test specimens were initially negative but became positive following further dilution of the extracts.     

HIV-infection in forensic autopsy cases

Sudden and unexpected death and violent death of persons with a high risk of acquiring HIV-infections, especially homosexual males and intravenous drug abusers, have to be investigated by forensic autopsies. Therefore every forensic pathologist has to be aware of this infection and should try to make the proper diagnosis. Three typical cases are described: (1) suicide by hanging, (2) homicide by cutting the throat and (3) intravenous heroin overdose. Merely retrospectively it could be cleared up that the deceased were homosexual but did not manifestly suffer from AIDS. The morphological findings in the lymph nodes and the postmortem serological findings are described in detail.     

POLICING CORPORATE COLLUSION*

This is a documentary study of the origin and investigation of all criminal prosecutions of collusive trade agreements filed by the Antitrust Division, US. Department of Justice from 1946 through 1970. The methodology seeks to reconstruct these cases from previously classified investigative files of the division. Observations include the sources of organizational intelligence, investigative methods, and encounters among antitrust victims, offenders, and officials. Most cases originate with complainants and informants outside the agency, but most evidence is obtained with the cooperation of offenders, who usually receive immunity or leniency in return. The conclusions suggest that public exposure of trade conspiracies serves as a deterrent despite weak penalties.     

A LATENT TRAIT APPROACH TO UNIFYING CRIMINAL CAREERS *

We propose a latent trait model that simultaneously accounts for both participation in crime and the frequency of crimes, phenomena that the criminal career model attributes to different causal processes. The criminal career model is predicated on a categorical distinction between active offenders and nonoffenders, but the latent trait model assumes a continuous distribution of propensity to offend. Our specific statistical model relates a relatively stable and general latent propensity to engage in crime to the frequency of criminal behavior. The latent trait model successfully fit both the proportion of offenders (participation) and frequency of offending for several samples and several measures of offending. The model fit both samples of whites and nonwhites and both males and females. This shows that separate causal processes are not necessary to account for group differences in frequency and in participation, which disproves the major evidence in favor of the criminal career model. Finally, the latent trait model yielded evidence that disparate sex differences in rates of participation for different categories of offenses are consistent with a single difference on a latent trait. This demonstrates the latent trait model's potential for parsimoniously unifying knowledge about criminal careers.     

Police enforcement of alcohol-related laws

Data are presented that indicate that the Southern region of the United States has a much higher arrest rate for drunkenness than other regions of the country; that the state of Kentucky has a much higher arrest rate for drunkenness and for alcohol offenses in total than even the Southern region; and that Madison County, Kentucky has much higher rates than even the state of Kentucky. Data collected from court records in Madison County are then presented to describe the people arrested for alcoholrelated offenses, the circumstances of their arrests, and the legal processing of their cases. Finally, speculative hypotheses for the higher arrest rates for alcohol-related offenses in the South, in Kentucky, and in Madison County are discussed.
