Analytical methods used for the discrimination of substances suspected to be bar soap: a preliminary study

The submission to forensic laboratories of unknown specimens suspected of being biological or chemical warfare agents has increased tremendously with the threat of terrorism. Oftentimes, a threatening correspondence that contains hoax materials is intended to make the recipient(s) believe they have been exposed to a toxin. In some cases, the perpetrator can use standard household products, such as detergents and soaps. Once these materials are received, they become forensic evidence and may be analyzed for identification and/or comparison with known seized material from a suspect(s). Two separate studies were conducted using different analytical protocols for bar soaps. In the first set, the forensic laboratory at the United States Secret Service conducted tests on 68 bars of soap using solid-phase microextraction and gas chromatography coupled with mass spectrometry. The 68 different soaps displayed unique total ion chromatogram profiles. Energy-dispersive X-ray analysis in conjunction with scanning electron microscopy was also used to characterize 46 of the 68 soaps as a preliminary study. In a second set of studies, as part of a homicide investigation, the laboratory at the California Department of Justice, Riverside, conducted examinations on 13 bars of soap by utilizing Fourier transform-infrared spectroscopy. The case study demonstrated that it is possible to distinguish some bar soaps using infrared analysis. Furthermore, the bar soaps could be distinguished from typical laundry detergents using this technique.     

Structured Assessment of Correctional Adaptation (SACA): a measure of the impact of incarceration on the mentally ill in a therapeutic setting

Clinicians have observed that psychiatric patients with correctional histories evidence attitudes and behaviors that seem adaptive in penal environments but are maladaptive in mental health settings. This study sought to assess the reliability and concurrent validity of a rating scale designed to measure correctional adaptation using a sample of 64 patients from a state psychiatric hospital. Scale ratings were obtained through structured interviews, whereas predictor variables were gleaned from chart review and self-report. The scale demonstrated good interrater reliability (ICC = .83) and acceptable internal consistency (alpha= .67). Of the variables evaluated, two were significantly correlated with Structured Assessment of Correctional Adaptation (SACA) total scores, total months sentenced to prison or jail (r = .26), and frequency of disciplinary tickets while in prison or jail (r = .31). Stepwise regression analyses revealed only the latter variable significantly predicted SACA score (R = .31), F(1, 58) = 6.27, p < .05. Clinical implications of these findings, the scale, and the construct of correctional adaptation are discussed.     

Family life education for young adolescents: A quasi-experiment

The impact of a family life education program for inner-city, minority elementary-school students was investigated. Two randomly assigned groups of seventh and eighth graders (balanced for gender) completed a self-administered survey, both before and after program implementation. In comparison to the control group, program participants displayed (a) improved knowledge about contraception, reproductive physiology, and adolescent pregnancy outcomes; (b) increased awareness of the existence of specific birth control methods; (c) among seventh graders, more conservative attitudes toward circumstances under which sexual intercourse was viewed as personally acceptable, and among eighth graders, a shift toward more liberal attitudes; and (d) a greater tendency to acknowledge mutual responsibility for contraception. The impact of this intervention and school-based sex education programs in general is discussed within the broader context of the young adolescent's social environment.This research was supported by grants from the Illinois Department of Children and Family Services and the Pittway Charitable Trust, and administered by the Ounce of Prevention Fund.Received Ph.D. from Loyola University Chicago.Received Ph.D. from the University of Michigan.Received Ph.D. from the State University of New York at Buffalo.
