BACKGROUND The honeybee has to detect, process and learn numerous complex odours from her natural environment on a daily basis. Most of these odours are floral scents, which are mixtures of dozens of different odorants. To date, it is still unclear how the bee brain unravels the complex information contained in scent mixtures. METHODOLOGY/PRINCIPAL(More)
Following an introduction to the broader context of the Symposium, the scope of the oral presentations is summarized under three themes: a global synthesis of fisheries impacts in different ecosystems; an overview of the methods available for quantifying ecosystem impacts; and the integration of fisheries and environmental management. The presentations(More)
Device pairing is a significant problem for a large class of increasingly popular resource-constrained wireless protocols such as BlueTooth. The objective of pairing is to establish a secure wireless communication channel between two specific devices without a public-key infrastructure, a secure near-field communication channel, or electrical contact. We(More)
The transfer of financial risk from health maintenance organizations (HMOs) to providers is controversial. To provide timely national data on these practices, we conducted a telephone survey in 1999 of a multi-staged probability sample of HMOs in 20 of the nation's 60 largest markets, accounting for 86% of all HMO enrollees nationally. Among those sampled,(More)

Many large-scale surveys currently use a variety of single imputation methods–as discussed by Chapman (1976), Cox (1980; and Kalton and Kasprzyk (1986)—to handle item nonresponse. Since the use of such imputation increases the underlying variation in the survey results, methods are needed to assess the impact. Until fairly recently, methods to assess the(More)

Evolutionary theories have always been treated by legal scholars as a sort of cousin to the legal theoretical family, both in Europe and the United States. They are nice theories, they tell interesting stories, you sometimes listen to what they have to say and when among friends, you may even quote them. However, in the modern mononuclear family, when it is(More)
Biocomplexity is the study of the structures and behaviors that arise from the interaction of biological entities such as molecules, cells, or organisms. While physical and chemical processes give rise to a great variety of spatial and temporal structures, the complexity of even the simplest biological phenomena is infinitely richer2. Over the past decade,(More)
