Ethnicity, gender, and the Level of Service Inventory-Revised

Offender assessment and classification is becoming an increasingly important part of correctional supervision and intervention. Over the last several decades, several different methods and “generations” of offender classification have emerged. Of most value appear to be third-generation, actuarial, dynamic risk/need assessments. With any new correctional strategy, however, there is a need to investigate the use of these risk/need assessments on offender subgroups in order to inform issues, such as reliability and prevalence of criminogenic risk factors. The present study utilized data that were gathered using the Level of Service Inventory-Revised (LSI-R). Results and comparisons of these assessments were investigated and presented for Native American and non-Native American offenders as well as male and female offenders. Discussion of the results, implications, and recommendations for further research are presented.     

Isolation of the DNA minisatellite probe MZ 1.3 and its application to DNA 'fingerprinting' analysis

A minisatellite probe, MZ 1.3, detecting hypervariable fragment patterns was isolated from a human genomic library. A repetitive sequence of 27 bp length was identified which is contained in the probe approx. 40 times. The MZ 1.3 repeat shows variable homology of 53-73% to the repetitive sequence of the protein III gene of the bacteriophage M13 genome. Polymorphic restriction fragment patterns were found with MZ 1.3 using the enzymes Hinf I, BstN I, Hae III, Mbo I, PstI/Pvu II, and Rsa I. An average of 18 polymorphic fragments was observed using Hinf I as enzyme. The band sharing frequency after Hinf I digestion among unrelated individuals was determined to be 23.8 +/- 7.2%. An example for the application of MZ 1.3 to paternity testing in an incest case is given. The probe can be used with radioactive or non-radioactive detection systems. An approach is presented to compare polymorphic fragment patterns from individuals obtained by independent gel runs on the basis of relative band positions (RBP) and calculated in a computerized analysis.     

Capillary gas-liquid chromatography separation of phenethylamines in amphetamine-positive urine samples

Good gas chromatography (GC) separation of molecules is essential for clean gas chromatography/mass spectrometry (GC/MS) confirmation of compounds. The trifluoro derivatives of ephedrine (E) and methamphetamine (MA) coelute on dimethyl silicone capillary columns, such as DB-1, which are most commonly used by chromatographers. Methods are described to separate E and MA to aid GC/MS confirmations of methamphetamine, ephedrine, or both E and MA together, whichever may be present in Enzyme Immunoassay (EIA)-analyzed amphetamine-positive urine samples. The use of the heptafluoro derivatives of E and MA on a DB-1 column, or the trifluoro derivatives of E and MA on a DB-17 column, is suggested for good gas chromatographic separation.     

Thirty Years of Social Science in Supreme Court Criminal Cases*

The Supreme Court early took note of extralegal, “social science” materials in Muller v. Oregon (1908), and a half-century later made specific reference to social science authorities in the famous footnote 11 of Brown v. Board of Education (1954). Since Brown, much has been written about the Supreme Court's use of social science research evidence, but there has been little systematic study of that use. Those writing on the subject commonly focus on areas of law such as jury size, where social science has been used, and have generally assumed that social science information has been utilized in Supreme Court decisions with increasing regularity. Surprisingly little is known, however, about either the justices' baseline use of social science authorities, or many other aspects of their uses of social science information. The focus here is on the citation of social science research evidence in a sample of 240 criminal cases decided during the 30 years between the Supreme Court's 1958 and 1987 Terms. The resulting portrait contributes to a fuller understanding of the justices' use of social science materials, and may ultimately help promote more effective utilization of social science research evidence in Supreme Court decisions.
