The human distribution of some barbiturate sedatives in combination with miscellaneous CNS-active drugs

This paper presents 14 cases in which the distribution of barbiturates and the hydroxylated metabolites in combination with miscellaneous CNS-active drugs was studied. In 7 of these cases the other drug present was methadone, and in the remainder dihydrocodeine, morphine, propoxyphene, amitriptyline, meprobamate, cyclizine and dipipanone, diphenhydramine and methaqualone.Amitrityline, methadone, cyclizine and dipipanone, methaqualone and diphenhydramine appeared to modify the distribution of amylobarbitone and quinalbarbitone. Likewise, the barbiturates seemed to alter the distribution of amitriptyline, propoxyphene and, in one instance, methadone.     

Toxicological investigations of six chlormethiazole-related deaths

This paper presents the toxicological findings for six coroners' autopsy cases where chlormethiazole was contributory to the cause of death. The drug, which was assayed by a gas-chromatographic procedure, was the only drug found in five of the cases.     

Chemical fingerprinting of unevaporated automotive gasoline samples

The comparison of two or more samples of liquid gasoline (petrol) to establish a common origin is a difficult problem in the forensic investigation of arsons and suspicious fires. A total of 35 randomly collected samples of unevaporated gasoline, covering three different grades (regular unleaded, premium unleaded and lead replacement), were examined. The high-boiling fraction of the gasoline was targeted with a view to apply the techniques described herein to evaporated gasoline samples in the future.A novel micro solid phase extraction (SPE) technique using activated alumina was developed to isolate the polar compounds and the polycyclic aromatic hydrocarbons (PAHs) from a 200microl sample of gasoline. Samples were analysed using full-scan gas chromatography-mass spectrometry (GC-MS) and potential target compounds identified. Samples were then re-analysed directly, without prior treatment, using GC-MS in selected ion monitoring (SIM) mode for target compounds that exhibited variation between gasoline samples. Principal component analysis (PCA) was applied to the chromatographic data. The first two principal components (PCs) accounted for 91.5% of the variation in the data. Linear discriminant analysis (LDA) performed on the PCA results showed that the 35 samples tested could be classified into 32 different groups.     

Workers' compensation: a background for Social Security professionals

This article provides a brief history and background of workers' compensation programs for occupationally injured and ill workers in the United States. It presents the basic principle involved in workers' compensation and briefly discusses the disability benefits to which workers are generally entitled. It also discusses why there are settlements in this disability program and the availability of information about the amounts paid in workers' compensation cases for obtaining an offset for Social Security Disability Insurance benefits paid to the worker. Finally, the article explains the rationale behind the public policy on coordination of Disability Insurance and workers' compensation in the new paradigm of disability and return to work.     

Democratic Deficit, the Global Trade System and 11 September

This short paper examines the Howard government's engagement with the World Trade Organization through the prism of two events: the S11 anti-globalisation protests and the 11 September terrorist attacks against the United States. Several policy dilemmas are highlighted including: concerns about the accountability and legitimacy of global political institutions (democratic deficit); the government's reluctance to expand public participation in trade policy-making; and the preference for bilateral rather than multilateral trade agreements. Together these developments have undermined Australia's commitment to multilateralism and a "rules-based" system for international trade, and have subjected Australia to the asymmetries of power that were traditionally mitigated by global political institutions.

Explaining Sibling Similarities: Perceptions of Sibling Influences

This study examined older siblings’ influence on their younger brothers and sisters by assessing the connections between youth's perceptions of sibling influence and sibling similarities in four domains: Risky behavior, peer competence, sports interests, and art interests. Participants included two adolescent-age siblings (firstborn age M=17.34; second-born age M=14.77) from 191 maritally intact families. Analyses revealed that second-borns’ perceptions of influence were positively linked to siblings’ reports of intimacy and temporal involvement, but not to reports of negativity. Further, sibling similarities were most evident when younger siblings reported sibling influence and when their older brothers and sisters reported high engagement, competence, or interest in a particular domain. Discussion focuses on the challenges of documenting sibling influence and the need to refine its measurement. Shawn D. Whiteman is an Assistant Professor of Child Development and Family Studies at Purdue University. He received his Ph.D. in Human Development and Family Studies from The Pennsylvania State University. His major research interests include how siblings directly and indirectly act as sources of social influence and social comparison within families and how their family experiences foster similarities and differences in their relationship qualities, attributes, and adjustment. Susan M. McHale is a Professor of Human Development and Family Studies at The Pennsylvania State University. She received her Ph.D. in Developmental Psychology from The University of North Carolina at Chapel Hill. Her major research interests focus on children's and adolescents’ family roles, relationships and activities with a particular emphasis on gendered family dynamics and youth's sibling relationship experiences.

Her major research interests focus on the implications of parents’ work situations for parents’ and children's health, psychological development, and family relationships.
