Many prior studies suggest that alphabetic ordering confers professional advantages on authors with earlier surname initials. However, these studies assume that authors select into coauthorships without regard to the incentives identified. We consider the alternative and develop a model of endogenous selection into single and coauthorships for economics, which uses alphabetical ordering. We the...

We consider the rewiring of a bipartite graph using a mixture of random and preferential attachment. The full mean-field equations for the degree distribution and its generating function are given. The exact solution of these equations for all finite parameter values at any time is found in terms of standard functions. It is demonstrated that these solutions are an excellent fit to numerical si...

The frequent use of non-representative, time-consuming and low hit rate sampling methods in the study of minority cultures is of concern. Given the increasing cultural diversity of the Canadian population and the growing Chinese population, a sampling method using phonological rules to distinguish Chinese surnames from non-Chinese ones was developed. Chinese surnames, transcribed according to t...

AIM The genetics underlying suicidal behavior is becoming increasingly recognized and investigated. Convergent evidence towards this end has emerged from numerous research strategies (adoption, family, genome-scan, geographic, immigrant, molecular genetic, surname, and twin studies of suicide). The topic-related mental-health literacy (i.e. knowledge and beliefs) of professionals and laypersons...

A multigene analysis of a combined ITS-LSU-SSU-rpb2-tef1 sequence data matrix was applied to infer the phylogenetic position of the genus Thyridaria in the Pleosporales. The generic type of Thyridaria, T. broussonetiae (syn. T. incrustans), is situated in a clade currently named Roussoellaceae, which becomes a synonym of Thyridariaceae. However, Thyridaria rubronotata does not belong to this cl...

Heritable surnames are highly diverse cultural markers of coancestry in human populations. A patrilineal surname is inherited in the same way as the non-recombining region of the Y chromosome and there should, therefore, be a correlation between the two. Studies of Y haplotypes within surnames, mostly of the British Isles, reveal high levels of coancestry among surname cohorts and the influence...

BACKGROUND Probabilistic record linkage is widely used in epidemiology, but studies of its validity are rare. Our aim was to validate its use to identify births to a cohort of women, being drawn from a large cohort of people born in Scotland in the early 1950s. METHODS The Children of the 1950s cohort includes 5868 females born in Aberdeen 1950-56 who were in primary schools in the city in 19...
