The Scarlet Gene: Behavioral Genetics, Criminal Law, And Racial And Ethnic Stigma, Karen H. Rothenberg, Alice Wang

Karen H. Rothenberg

Imagine that a scientist from the state university asks you and your family to participate in a study on a particular gene variant associated with alcoholism. The project focuses on your ethnic group, the Tracy Islanders, who have a higher incidence of alcoholism, as well as a higher incidence of the gene variant, than the general population. You will not be informed whether you have the gene variant, but your participation in the study might help scientists develop drugs to help individuals control their addiction to alcohol.

Small landholders are more innovative, with 12% of Australia’s farm forestry plantations under mixed-species plantings, and 80% of Queensland’s farm forestry as polycultures. We examine reasons for this discrepancy, and explore the history, silviculture and economics of polycultures. Financial analyses suggest that a yield stimulus of 10%, depending on product and rotation length, may be sufficient to offset increased costs associated with planting and managing a mixed-species plantation, a stimulus that has been demonstrated in many field …
