Arylamine N-acetyltransferase 2 (NAT2) is involved in human physiological responses to a variety of xenobiotic compounds, including common therapeutic drugs and exogenous chemicals present in the diet and the environment. Many questions remain about the evolutionary mechanisms that have led to the high prevalence of slow acetylators in the human species. Evidence from recent surveys of NAT2 gen...

—This paper presents a synopsis of discussions by commercial and subsistence fishers, biologists, fishery managers, and academicians about salmon management held at the symposium (this volume). The group reviewed current strategies and discussed changes that may be made to improve management with respect to fish numbers, stakeholder needs, and engagement of local people. The conservation of sal...

Purpose: In this article we illustrate the importance of understanding the risk profiles of new technologies, in addition to the changes in productivity, to be able to determine strategies for agricultural development. Design/methodology/approach: The analysis is based on data obtained from a 2002 survey of subsistence farmers in the Kilimanjaro region of Tanzania, and a Just and Pope (1978) fr...

BACKGROUND Populations in transition to a Western lifestyle display increased incidences of obesity, type 2 diabetes, and other chronic diseases; the mechanisms responsible for these changes, however, remain incompletely understood. Although reduced physical activity has been implicated, few studies have accurately quantified energy expenditure in subsistence populations. OBJECTIVE The aim of...

a r t i c l e i n f o Rural areas often have more than one regime of property rights and production. Large, private-property farms owned by powerful landowners coexist with subsistence peasants who farm small plots with limited property rights. At the same time, there is broad consensus that individual, well-specified and secure property rights over land improve economic outcomes. If property r...
