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...

In the early years, theories of family therapy were built on earlier schools of thought such as Kurt Lewin's field theory, which was used extensively in group settings; and Alfred Adler's Child Guidance Movement, which suggested that psychopathology begins in childhood and can be treated with family involvement. However, family systems theory was most directly inspired and ignited by the cybern...

Erratum After publication of this work [1], it has come to our attention that Lone Graff Stensballe's surname was displayed incorrectly. The full list of authors has now been updated. We are publishing this erratum to update the author list, which is as follows: Disappointment and adherence among parents of newborns allocated to the control group: a qualitative study of a randomized clinical tr...

BACKGROUND Methods of estimating race/ethnicity using administrative data are increasingly used to examine and target disparities; however, there has been no validation of these methods using clinically relevant outcomes. OBJECTIVE To evaluate the validity of the indirect method of race/ethnicity identification based on place of residence and surname for assessing clinically relevant outcomes...

Most national health surveys do not permit precise measurement of the health of racial/ethnic subgroups that comprise <1 per cent of the U.S. population. We identify three potentially promising sample design strategies for increasing the accuracy of national health estimates for a small target subgroup when used to supplement a small probability sample of that group and apply these strategies t...

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...

Following publication of the original article [1], one of the authors reported that prior to publication her surname had changed from 'Kerlen' to 'van der Kruk', but that this change had not been incorporated in the final version.

T he experience of parenthood is considered to be central to individual identity and to the life plan of most people in most societies. There are many reasons for wanting children: to give and receive love, as an expression of the couple’s unity, to give meaning or add value to one’s life, for the enjoyment or pleasure of children, to carry on the family name, to be like other friends, to give ...
