This paper examines how estimates of the price elasticity of demand for beer vary with the choice of alcohol price series examined. Our most important finding is that the commonly used ACCRA price data are unlikely to reliably indicate alcohol demand elasticities-estimates obtained from this source vary drastically and unpredictably. As an alternative,(More)
The crepuscular biting rhythm of A. subalbatus has been found to be a genuine circadian rhythm. When the entrained biting rhythm is allowed to freerun in constant darkness (DD) and continuous illumination (LL), it persists in DD (tau = 24.36 hr) and also in LL of ca. 0.1 1x (tau-23.82 hr) thus deviating from the strict 24 hr periodicity of the geophysical(More)
The biting cycle of Armigeres subalbatus is distinctly crepuscular, exhibiting two peaks of activity, a smaller one at dawn and a larger one at dusk. The biting cycle is entrained to natural light-dark cycles and the time interval from dawn to dawn or dusk to dusk peaks is exactly 24 h and from dawn to dusk or dusk to dawn is about 12 h measured at 50%(More)
