Perceived Water Prices and Estimated Water Demand in the Residential Sector of Windhoek, Namibia. An Analysis of the Different Water Market Segments

We develop a demand model for the water market of Windhoek, Namibia, and segment the market by income. The model uses the perceived price concept developed by Shin (1985). Results confirm the Shin hypotheses that consumers dont know actual prices, but respond to perceived prices. The average price and covariates have the expected signs. However, marginal price (MP) coefficient is positive. Shins perception parameter (k) is negative in two of three income segments. In the Shin model, this implies that consumers respond to MP (through perceived prices). Ambiguities about prices warrant further investigation.Resource /Energy Economics and Policy,

Effects of Generic Advertisement on Demand: The Case of the Washington State Apple Commission

The Washington Apple Commission (WAC) generically promoted apples for the Washington state industry from 1937 until 2003. This paper provides an analysis of the effects on demand attributable to these activities. Demand movement associated with promotion tends to be positive, though the results are mixed. Overall, WAC promotion increased growers’ total revenue by approximately $53.4 million for 2002. The estimated average return to advertising topped$8.7 per dollar of advertising. Continuing selected promotional activities could increase revenue for growers if these activities could be carried out by voluntary, coordinated efforts.Demand and Price Analysis,

Ocean Chlorophyll Studies from a U-2 Aircraft Platform

Chlorophyll gradient maps of large ocean areas were generated from U-2 ocean color scanner data obtained over test sites in the Pacific and Atlantic Oceans. The delineation of oceanic features using the upward radiant intensity relies on an analysis method which presupposes that radiation backscattered from the atmosphere and ocean surface can be properly modeled using a measurement made at 778 nm. An estimation of the chlorophyll concentration was performed by properly ratioing radiances measured at 472 nm and 548 nm after removing the atmospheric effects. The correlation between the remotely sensed data and in-situ surface chlorophyll measurements was validated in two sets of data. The results show that the correlation between the in-situ measured chlorophyll and the derived quantity is a negative exponential function and the correlation coefficient was calculated to be -0.965

Linear Self-Motion Cues Support the Spatial Distribution and Stability of Hippocampal Place Cells

The vestibular system provides a crucial component of place-cell and head-direction cell activity [1-7]. Otolith signals are necessary for head-direction signal stability and associated behavior [8, 9], and the head-direction signal's contribution to parahippocampal spatial representations [10-14] suggests that place cells may also require otolithic information. Here, we demonstrate that self-movement information from the otolith organs is necessary for the development of stable place fields within and across sessions. Place cells in otoconia-deficient tilted mice showed reduced spatial coherence and formed place fields that were located closer to environmental boundaries, relative to those of control mice. These differences reveal an important otolithic contribution to place-cell functioning and provide insight into the cognitive deficits associated with otolith dysfunction
