Wounding effects of the AK-47 rifle used by Patrick Purdy in the Stockton, California, schoolyard shooting of January 17, 1989

The limited disruption produced in tissue simulant by the rifle and bullets used in the Stockton, California, schoolyard shooting is entirely consistent with the autopsy reports on the five children who died of their wounds. It is also entirely consistent with well-documented battlefield studies and with previous tissue-simulant studies from many laboratories. It is inconsistent with many exaggerated accounts of assault-rifle wounding effects described by the media in the aftermath of this incident. This information should be documented for the historical record. However, the critical reason for correcting the misconceptions produced by media reaction to this incident is to prevent inappropriate gunshot-wound treatment.     

POLITICAL CRIME, POLITICAL JUST1CE, AND POLITICAL PRISONERS

Few attempts have previously been made systematically to define or interrelate the concepts of political crime, political criminal, political justice, and political prisoner. To establish a more adequate conceptual base for research, political crime and political criminals are herein defined in terms of motiwtions underlying criminal acts, regardless of the nature of the acts themselves; political justice is defined in terms of the state's reaction to perceived threat; and political prisoners are defined as those incarcerated because of either political crime (politico1 criminals) or political justice (victims of repression). Dimensions for a taxonomy of political crime are suggested.     

The autodegradation of deoxyribonucleic acid (DNA) in human rib bone and its relationship to the time interval since death

This research explored the feasibility of using the degradation rate of deoxyribonucleic acid (DNA) in human rib bone to determine the time interval since death. Postmortem human rib samples were surface sterilized and incubated under sterile conditions in either high or low humidity conditions at room temperature for a period of weeks. At selected times, portions of the bone were cut away, and the DNA from these samples was extracted and subjected to strand separating gel electrophoresis. The DNAs in the gels were transferred to a nylon membrane, preserving their relative positions as in the gel, and probed with radioactive total genomic human DNA. Autoradiograms produced were scanned and digitized. When the samples were incubated under identical conditions, the degradation rate of DNA in samples from different individuals appeared very similar. The DNA degradation rate may vary with temperature and humidity more than it varies between individuals.     

THE AMBIGUOUS JUVENILE ARREST

Uniformity of juvenile arrest definitions and operations was investigated in 49 police stations in rural, suburban, and large urban areas. Data were taken from interviews and questionnaires administered to police chiefs, clerks, and officers, as well as from on-site observations. The meaning of a juvenile arrest was found to vary widely and to reflect poorly the statutory requirements. Greatest uniformity was found among recording clerks. Their practice of recording as an arrest any juvenile brought or cited into the station provides a useful operational definition. Implications of these data for uniform crime reporting, program evaluation, and equal justice are suggested.     

Policy analytic implications for a theory of prediction and decision

Decision theory developed to prescribe the consistent choice behavior under uncertainty of an ideal individual. The policy analysis context of organizational decision-making, however, necessitates certain modifications to the fundamental decision theory in order to deal with the problems of group consensus, ill-defined objectives and disparate information sources. The argument is presented that more attention must be given to the explicit formulation of judgment and that, in particular, there has to be an integration of the methodology of forecasting into the decision-analytic framework. A consequence of adopting a decision-theoretic approach to forecasting is the apparent need to develop ways of synthesizing the set of available predictive methods in order to satisfy the subjectivist principle of total evidence utilization. The synthetic approach to forecasting is in contrast to the conventional selective method. A brief review of some operational methods of pursuing the synthetic approach is given.
