Construct Validity of Adolescent Antisocial Personality Disorder

This study examined the construct validity of antisocial personality disorder (ASPD) diagnosed in adolescence. Boys and girls were grouped by history of DSM-III-R conduct disorder (CD) and ASPD: Controls (n=340) had neither diagnosis; CD Only (n=77) had CD by age 17 but no ASPD through age 20; Adolescent ASPD (n = 64) had ASPD by age 17. The Adolescent ASPD group was then compared to 20 young adult men who met criteria for ASPD (ASPD group). As expected, the Adolescent ASPD group had significantly more depression and substance use disorders, a greater performance>verbal IQ discrepancy, more deviant peers, and poorer academic functioning than the CD Only group and Controls. The Adolescent ASPD and ASPD groups did not differ on most variables. Results support the construct validity of Adolescent ASPD and suggest that such a diagnosis could help identify adolescents at risk for persistent antisocial behavior.

Major study commencing into genetic discrimination in Australia

This article describes a nationwide empirical study that will be undertaken during the next three years into the newly emerging phenomenon of genetic discrimination. In particular, the study aims to investigate the nature and extent of genetic discrimination in Australia across three key perspectives: consumers, third parties and the legal system. Further, the study aims to examine the social and legal implications of genetic discrimination, with a view to making recommendations for use in the Australian legal and policy context. It is anticipated that the data produced from this multifaceted investigation will assist in identifying areas where legal or other reforms are required. It will contribute significant baseline data for facilitating ongoing assessment of the nature and extent of the problem, as well as for longitudinal evaluation of the impact and effectiveness of any reforms which may be introduced in the future to address the issue.     

Compositional variation in bullet lead manufacture

The concentrations of antimony, copper, tin, arsenic, silver, bismuth, and cadmium in lead alloys produced by two smelters and one ammunition manufacturer were determined using inductively coupled plasma-atomic emission spectrometry. These element concentrations were used to measure the variations in composition of lead products that result from various processes involved in the manufacture of lead projectiles. In general, when a pot containing molten lead is used to cast a number of objects, these objects are similar, although not necessarily analytically indistinguishable in their elemental compositions. In each subsequent step in the processing of lead at the smelter and at the ammunition manufacturer, the size of an individual homogeneous melt of lead decreases as more distinct compositions are formed as a result of remelting and mixing of sources, including lead scrap. The ammunition manufacturer in this study produced at least 10 compositionally distinguishable groups of bullet wire in a 19.7-h period. The largest group could potentially be used to produce a maximum of 1.3 million compositionally indistinguishable 40 grain bullets.     

Validation of chest X-ray comparisons for unknown decedent identification

Comparing skeletal structures between antemortem and postmortem chest radiographs is widely used by forensic specialists from many disciplines to positively identify unknown decedents. However, validity assessments of this method have been fairly limited. This study had three objectives: 1) to quantify the reliability of ante- and postmortem chest radiograph comparison for decedent identification; 2) to identify useful radiologic features supporting decedent identification; and 3) to recognize sources of error in decedent identification related to use of comparative radiographs. A forensic pathologist, a forensic anthropologist, and two radiologists participated in the study. Our results showed that chest radiograph comparisons proved reliable, if basic decedent information was provided, and antemortem and postmortem radiographs were adequately positioned and exposed. A "morphological approach" using normal anatomical structures for comparison may provide the most efficient method for accurate identification.     

Evaluation of some oxygen, sulfur, and selenium substituted ninhydrin analogues, nitrophenylninhydrin and benzo[f]furoninhydrin

Six ninhydrin analogues containing oxygen, sulfur, and selenium substituents at the C-5 position, 5-(4-nitrophenyl)ninhydrin, and benzo[f]furoninhydrin were evaluated as fingerprint development reagents. The analogues all showed good fingerprint color development but were not superior to ninhydrin in this respect. The benzo[f]furoninhydrin complex was strongly luminescent at room temperature following zinc complexation, while the remaining analogues required cooling to -196 degrees C to produce optimum luminescence. The benzo[f]furo, nitrophenyl, and methyl selenide analogues showed the best potential as fingerprint reagents with the benzo[f]furo analogue comparing favorably with DFO.     

The Israel and Palestine land settlement problem, 1948–2005: An analytical history

This paper traces the history of the current conflict between Israel and Palestine from 1948–2005 C.E. It focuses on the frontier conflict between Israel and Palestine, a conflict that has resulted in four major wars during the post-Second World War period, and that has left Israel as the occupying power over a large swathe of territory not allocated to it by the United Nations in 1947. It outlines the nature of the refugee problem in Palestine and neighboring Arab states, and defines the political problems posed both by relative Israel-Palestine population growth, and by the `right to return’ claim by ousted Palestinian Arabs. It reviews the political problems posed by religious extremism and theocratic government both in Israel and Palestine. It concludes with a brief discussion of the unpleasant alternatives left as the road map to peace disintegrates and outlines a preferred solution from the perspective of the advanced western nations.
