Exclusionary DNA of forensic workers and Australian forensic procedures legislation

Consideration of regulatory issues covering exclusionary DNA of forensic workers - probative effect of eliminating extraneous DNA in a criminal prosecution - current regulatory scheme leaves the legal position of forensic workers' exclusionary DNA obscure.

Dominance hierarchies and health: Constructing personal zones of spiritual power and healing in modern medicine

Ethological studies of animals in groups and sociobiology indicate that hierarchies of dominance amongst some species ensure the survival of the group. When transferred to human groups, dominance hierarchies suggest a crucial role played by recasting the scope of such hierarchies of dominant and subordinate members to included hyper-dominant beings. A recognition of such beings as even more dominant than the socially dominant members of a hierarchy facilitates the empowerment of the socially subordinate members. Religious belief and practice works to establish such hyper-dominant beings (gods, goddesses, and so forth) as superior members of human groups. Doing so is a means of ensuring the survival of the species and, thus, enhancing healing and human health. The doctor-patient relationship is examined from such a point of view, with an emphasis on whether the hierarchy created by the relationship allows consideration of alternative and complementary forms of medical treatment.

Pesticide and herbicide residues in sediments and seagrasses from the Great Barrier Reef world heritage area and Queensland coast

Pesticides and herbicides including organochlorine compounds have had extensive current and past application by Queensland's intensive coastal agriculture industry as web as for a wide range of domestic, public health and agricultural purposes in urban areas, The persistent nature of these types of compounds together with possible continued illegal use of banned organochlorine compounds raises the potential for continued long-term chronic exposure to plants and animals of the Great Barrier Reef. Sediment and seagrass samples were collected from 16 intertidal and 25 subtidal sampling sites between Torres Strait and Townsville, near Mackay and Gladstone, and in Hervey and Moreton Bays in 1997 and 1998 and analysed for pesticide and herbicide residues. Low levels of atrazine (0.1-0.3 mug kg(-1)), diuron (0.2-10.1 mug kg(-1)), lindane (0.08-0.19 mug kg(-1)), dieldrin (0.05-0.37 mug kg(-1)), DDT (0.05-0.26 mug kg(-1)), and DDE (0.05-0.26 mug kg(-1)) were detected in sediments and/or seagrasses. Contaminants were mainly detected in samples collected along the high rainfall, tropical coast between Townsville and Port Douglas and in Moreton Bay. Of the contaminants detected, the herbicide diuron is of most concern as the concentrations detected have some potential to impact local seagrass communities, (C) 2000 Elsevier Science Ltd.
