A Farewell to Alms: A Brief Economic History of the World, argued controversially that in pre-industrial England the rich replaced the poor demographically, and that this helps explain why England became more “bourgeois” in these years: less violent, thriftier, more literate, more numerate. Here evidence from a different source, surnames, confirms the takeover of English society by the economic...

According to many phenomenological and theoretical studies the distribution of family name frequencies in a population can be asymptotically described by a power law. We show that the Galton-Watson process corresponding to the dynamics of a growing population can be represented in Hilbert space, and its time evolution may be analyzed by renormalization group techniques, thus explaining the orig...

s are sorted first by session and then alphabetically by presenter’s last name. Presenters’ names are in bold and underlined print. The Author Index includes all authors, co-authors, their paper IDs and page numbers. Some abstracts in this collection have not been edited and have been printed in the condition that they were received.

The continuing expansion of Internet media consumption has increased traffic volumes, and hence congestion, on access links. In response, both mobile and wireline ISPs must either increase capacity or perform traffic engineering over existing resources. Unfortunately, provisioning timescales are long, the process is costly, and single-homing means operators cannot balance across the last mile. ...

The interventions aimed at the early childhood are of a main interest in educational policy, since it is in this period when it is possible to produce a major impact in the subsequent human development. The quality of children’s social environment is the main influence to consider in achieving sound child development, affecting throughout school life. For this reason, the development of child’s...

The recent availability of World Wide Web-based directories has opened up a new approach for tracing subjects in epidemiologic studies. The completeness of two World Wide Web-based directories (Canada411 and InfoSpace Canada) for subject tracing was evaluated by using a randomized crossover design for 346 adults randomly selected from respondents in an ongoing cohort study. About half (56.4%) o...

The Rama Amerindians from southern Nicaragua are one of few indigenous populations inhabiting the east coast and lowlands of southern Central America. Early-eighteenth-century ethnohistorical accounts depicted the Rama as a mobile hunter-gatherer and horticulturalist group dispersed in household units along southern Nicaraguan rivers. However, during the nineteenth and twentieth centuries, Rama...

With the increasing number of competing mobile services, the process of acquiring new, and retaining existing customers becomes harder. Acquisition of new customers can, to some degree, be done with increased marketing efforts, but marketing has less effect for retaining existing customers, since they allready know the service. Improving the mobile service is likely to be the best way to retain...

Although it is well established that Hispanics generally have a mixed Native American, African, and European ancestry, the dynamics of admixture at the foundation of Hispanic populations is heterogeneous and poorly documented. Genetic analyses are potentially very informative for probing the early demographic history of these populations. Here we evaluate the genetic structure and admixture dyn...
