Estimating Price Paths for Residential Real Estate

Several approaches have been used to estimate and adjust for price movements in residential real estate; however, weaknesses remain in current systems. This paper incorporates a different way of measuring temporal price patterns. The method involves a time series model, an approach not previously employed when estimating real estate price movements. Using illustrative data, it is indicated that the proposed technique is likely more accurate than current procedures. The method also represents a significant adaptation of standard time series models. For the task at hand, the new model is arguably preferable to these more standard versions.

Burgon - A Hooded Progress

With the marked increase in the number of universities in the United Kingdom and the authorisation of robes by many of the colleges and learned societies, identification of a wearer’s academic achievement or distinction has become as complex a study as that of train-spotting used to be in the sorely missed bygone days of steam

Biopharmaceuticals from Mammalian Cells

The advent of genetic engineering and monoclonal antibody technologies has made possible the manufacture of a wide range of pharmaceutical proteins. Many of these proteins are made in mammalian cell culture. This has required the development of novel gene-expression systems as well as technology for the large-scale culture of cells and for the isolation of proteins to exacting standards of purity. Lonza has established facilities in the UK and the USA for the contract development and manufacture of these proteins

THEMIS observations and riometry: A data comparison with a view to proxy and prediction

A comparison has been made between radio absorption events observed by riometer at selected times of day and bursts of electrons observed in the midnight sector by THEMIS satellites. The correlation is found to be good for absorption in the noon and midnight sectors but poor around dawn and dusk. For noon and midnight the absorption can be estimated from the THEMIS electron flux to better than a factor of 2 in most cases. In the noon sector the absorption follows the THEMIS event by about 30 min on average (though with considerable variation from case to case), but by night the absorption precedes the electron flux by about 8 min on average. Thus, the flux at THEMIS can be predicted from the absorption in the night sector, the accuracy being better than a factor of 3 in most cases. The flux observed also depends on the location of the satellite, reducing with increasing distance down the tail. It is estimated that the source of the tail events observed in this study was at about 6Re, and comparisons are made with the established general pattern of the substorm in auroral absorption

Stochastic Reserve Losses: A Rejoinder

In an article in the September, 1961, issue of the A.merican Economic Review, Daniel Orr and W. G. Mellon introduced the notion of uncertainty into the well-known comparative static analysis of bank credit expansion. (1) This paper discusses their findings, the nature of their assumptions, and some possible extensions of their results
