In 1970 Vernon Booth was awarded the first Prize in a competition organized by Koch-Light Laboratories Ltd, Coinbrook, Bucks., U.K.. His article 'Writing a Scientific Paper' was printed first in 1971, and 10000 copies were distributed freely by Koch-Light. A Second Edition was prepared by Dr Booth and distributed privately. Copies of the First and Second Editions are no longer in print but requ...

BACKGROUND The neurocognitive functioning of patients with schizophrenia is likely to decline at the early stage of the illness. More evidence is needed to determine whether deficits in certain domains of neurocognition precede the onset of illness and can predict the onset of psychosis. METHODS Subjects were recruited from the SOPRES study in Taiwan. A neuropsychological battery including th...

established in 1988 and is published by the International Centre for Eye Health, based at the London School of Hygiene and Tropical Medicine. It has editions in French, Chinese, and Spanish, and there is a special edition for India. Paper copies of the journal, in all four languages, are sent to over 35,000 people in 183 countries (see map). We would like to thank everyone who completed our rec...

The Fourth IEEE International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob 2008) has introduced workshops in its 2008 edition featuring a wider range of topics on current and emerging research areas. The purpose of these workshops is to provide a more focused presentation and discussion forum on ongoing research, practical experience and completed research r...

The mathematical study of genealogies has yielded important insights in population biology, such as the ability to estimate the time to the most recent common ancestor (MRCA) of a sample of genetic sequences or of a group of individuals. Here we introduce a model of cultural genealogies that is a step toward answering similar questions for cultural traits. In our model individuals can inherit f...

An important clue to the evolutionary history of an allele is the structure of the neighboring region of the genome, which we term the genomic background of the allele. Consider two copies of the allele. How similar we expect their genomic background to be is strongly influenced by the age of their most recent common ancestor (MRCA). We apply diffusion theory, first used by Motoo Kimura as a to...

The mutation process is introduced into the colored coalescent theory. The mutation process can be viewed as an independent Poisson process running on the colored genealogical random tree generated by the colored coalescent process, with the edge lengths of the random tree serving as the time scale for the mutation process. Moving backward along the colored genealogical tree, the color of verti...

The genealogies of samples of orthologous regions from multiple species can be classified by their shapes. Using a neutral coalescent model of two species, I give exact probabilities of each of four possible genealogical shapes: reciprocal monophyly, two types of paraphyly, and polyphyly. After the divergence that forms two species, each of which has population size N, polyphyly is the most lik...
