Unlike the pandemic form of HIV-1 (group M), group O viruses are endemic in west central Africa, especially in Cameroon. However, little is known about group O's genetic evolution, and why this highly divergent lineage has not become pandemic. Using a unique and large set of group O sequences from samples collected from 1987 to 2012, we find that this lineage has evolved in successive slow and ...

Since 1993 many seizures of 1-phenylethylamine have been made in several European countries. It was originally thought that 1-phenylethylamine had been made in error, but later information suggested that it had been prepared deliberately. The related compounds, 1-amino-1-(4-methylphenyl)ethane and 1-methylamino-1-phenylethane and the 1-propanamine isomer of 3,4-methylenedioxyamphetamine, have a...

When people talk, they gesture. We show that gesture introduces action information into speakers' mental representations, which, in turn, affect subsequent performance. In Experiment 1, participants solved the Tower of Hanoi task (TOH1), explained (with gesture) how they solved it, and solved it again (TOH2). For all participants, the smallest disk in TOH1 was the lightest and could be lifted w...

We have set up a brain-computer interface (BCI) to be used as an input device to a highly immersive virtual reality CAVE-like system. We have carried out two navigation experiments: three subjects were required to rotate in a virtual bar room by imagining left or right hand movement, and to walk along a single axis in a virtual street by imagining foot or hand movement. In this paper we focus o...

This study examined associations between mother-infant nighttime interactions and mother-infant attachment when infants were 12 months old. Forty-four mother-infant pairs participated in this study. For three consecutive nights at home, babies were observed in their cribs using a digital video system. Mothers reported on their nighttime interactions with their babies using a self-report diary a...

This paper reports a case study of a Community of Practice (CoP) of tertiary educators in information technology (IT), who seek ways to obtain adequate IT support to match their particular work environment. A facilitated workshop sought to bring members of the CoP and a key representative of the central IT department together with the aim of creating common ground for improved communication and...
