Spatial data, either areal or geostatistical (point-referenced), are becoming increasingly utilized in the study of many scientific fields due to the accessibility of data monitoring systems and associated datasets. When both types of data are available for the same underlying spatial process, computationally efficient and statistically sound methods are needed for their joint analysis. Markov ...

Acknowledgements I would like to thank the people who made my time here in Oxford possible, and those who made it what it was-a great journey. Specifically, thanks go to my parents for giving me so much freedom to choose the path which led me here that at times I thought they didn't care. Thanks also to whoever thought it would be a good idea to give young Adelaideans the financial support nece...

The generic relationships of the Wood Thrush (Hylocichla mustelina) have been called into question by the works of Dilger (1956) and Bourns (1967). The four species of North American woodland thrushes presently referred (32nd Supplement to the A.O.U. Checklist 1973) to the genus Catharus i.e., Hermit Thrush ( Catharus @tutu) ; Gray-cheeked Thrush (C. minima); Swainson’ s Thrush (C. ustuluta); a...

Although much is known about the physiology of the neuromuscular junction and its role in initiating muscular contraction in crustaceans, less attention has been devoted to the central events which select and control contraction. The mechanisms which shape the discharge patterns of motoneurons are best known for the escape reflex of the crayfish abdomen, mediated by giant fibres, and for the ne...

George A. Bray was born 25 July 1931 in Winnetka, IL, during the peak of the Depression. He was the first child of George August and Mary H. Bray. His only sibling, Mary Elizabeth (Betsy) Bray, died secondary to rheumatic heart disease. Influenced by his mother, George developed a natural interest in education at a young age, even though one of his teachers at Hubbard Woods School in Winnetka r...

Welcome to the first issue of R News in 2003, which is also the first issue where I serve as Editor-in-Chief. This year has already seen a lot of exciting activities in the R project, one of them was the Distributed Statistical Computing Workshop that took place here in Vienna. DSC 2003 is also partly responsible for the rather late release of this newsletter, both members of the editorial boar...

Articles R emote sensing has facilitated extraordinary advances in the modeling, mapping, and understanding of ecosystems. Typical applications of remote sensing involve either images from passive optical systems, such as aerial photography and Landsat Thematic Mapper (Goward and Williams 1997), or to a lesser degree, active radar sensors such as RADARSAT (Waring et al. 1995). These types of se...

Lord Chief Baron's opinion?which he (Dr. Wingett) declares to have " already done much mischief in the judicial proceedings of Scotland" ?yet declares that? " It is, palpably, the grossest absurdity to impeach the judge for the results of this case; he has merely propounded the law?extreme law it may be-?but the law nevertheless. The law only is at fault, and if we insist upon attacking the law...

This paper presents the first results of an experimental study concerning the semantic status of borderline cases of vague predicates. Our focus is on the particular case of color predicates (such as ‘yellow’, ‘orange’, ‘blue’, ‘green’), and on the influence of context in the categorization of color shades at the border between two color categories. In an unpublished study, D. Raffman and colle...

A frequent problem in ecology is determining whether the observed spatial distribution of a plant species can be attributed to a completely random spatial process. Usually the analysis of these data is simplified by the fact that the locations of the plants are the two-dimensional coordinates in a rectangular region. This paper considers a more difficult problem of assessing the spatial pattern...
