Threat mail and forensic science: DNA profiling from items of evidence after treatment with DFO

Two cases of threatening letters with their accompanying envelopes were received to the Division of Forensic Identification unit of the Israel Police. The envelopes, including the stamps, and the letters were initially examined for latent fingerprints by the DFO reagent, known to cause degradation of DNA. Although no latent fingerprints could be visualized on any of the items, the biology laboratory using organic DNA extraction, was successful in defining genetic profiles from all the items employing six STR loci, even after treatment with DFO. In a controlled experiment, a known donor attached a stamp, by licking, to an envelope. This item was treated with DFO and then profiled using STR loci. The results showed that previous DFO treatment on the control stamp before DNA analysis had no negative effects on obtaining the DNA profile of the known donor using STR loci.     

The Baha’i minority in the State of Israel, 1948–1957

This article examines the virtually unexplored topic of the Baha'i religious minority in Israel's early statehood period based mainly on primary source documentation. It will be argued that while the number of Persian Baha'is in Israel after 1948 was minuscule — even smaller than the similarly minuscule Circassian and Armenian populations — the non-Arab and non-Muslim identity of the Baha'is, the lack of any historical antagonism between the Baha'is and the Jews, a shared history of marginalization in the modern Middle East, the Baha'is' principled commitment to non-violence as a basic tenet of their religious faith, their complete neutrality leading up to and including the 1948 War, (and their support for Jewish statehood after it), their lack of proselytizing in the state of Israel, and the fact that nearly all of their high-ranking administrators in post-independence Israel hailed from the United States — whose support Israel sought — led the state to cultivate this minority to a degree few other minorities experienced in post 1948 Israel.

A study of the flight and return of most (excommunicated) Baha'i adherents during and after the 1948 War, respectively, will form part of a separate, forthcoming article.     

Conflict in the home environment of adolescents from divorced families: A longitudinal analysis

The purpose of this study was to examine conflict in the home environment of adolescents from divorced families across a 3-year period. Adolescents from intact (106) and mother-custody divorced (60) families participated. Interparental conflict and parent-adolescent relations were assessed. Results indicated that adolescents from divorced families did not experience more conflictual home environments than those from intact families. In fact, interparental relations after the first year and parent-adolescent relations in general appeared to be less conflictual in divorced families. Limitations and implications of the findings are discussed.     

Risk and Protective Factors Associated with Alcohol,Cigarette, and Marijuana Use During Adolescence

The purpose of this study was to increase the knowledge base of adolescent substance use by examining the influences of risk and protective factors for specific substance use, namely alcohol, cigarettes, and marijuana. Participants included 271 adolescents and their primary caregivers referred for mental health services across North Carolina. A series of hierarchical multiple regressions showed that the relative influences of risk and protective factors differed depending on the target substance in some cases. History of parental felony predicted use of all 3 substances, although the direction of association was substance specific. Parental behavioral control (how families express and maintain standards of behavior) was predictive only of cigarette and marijuana use, not alcohol use. The different links among risk factors, protective factors, and specific substance use are discussed, and recommendations for both mental health and substance use professionals are offered.She received her M.A. in Psychology from Wake Forest University and is currently a doctoral student in Clinical Psychology at the University of North Carolina at Greensboro.
