Much of the evolutionary literature on human mating is based on the assumption of extensive female choice during the history of our species. However, ethnographic evidence from foraging societies reveals that, in societies thought to be akin to those of our ancestors, female choice is constrained by the control that parents exercise over their daughters. Data from 190 hunting and gathering soci...

The UN Committee on the Rights of the Child has criticised Australia (and many other countries) in State Reports released in 1997, 2005 and, most recently, 2011, for not introducing a ban on corporal punishment by parents of their children in line with Article 19 of the UN Convention on the Rights of the Child (‘CROC’). In light of this criticism, and the clear recommendation to ban parental co...

Sex, birth order, and age of the mother are a few factors demonstrated to influence levels of parental investment (especially as measured by offspring self-r...

National context may influence sex segregation of household tasks through both pragmatic decision making and the normative context in which decision making is embedded. This study utilizes 36 time use surveys from 19 countries (spanning 1965-2003) combined with original national-level data in multilevel models to examine household task segregation. Analyses reveal that men do less and women do ...

in this paper, using generalized {polya} urn models we find the expected value of the size of a branch in recursive $k$-ary trees. we also find the expectation of the number of nodes of a given outdegree in a branch of such trees.

Recent formulations of socialization emphasize a previously neglected facet of parent-child interaction—the effects of child attributes on parent behavior. Empirically, however, little has been done to clarify which attributes of children systematically affect parental behavior and how they affect them. This study examines the relationship between children's activity level and independently ass...

This paper reviews P´olya urn models and their connection to random trees. Basic results are presented, together with proofs that underly the historical evolution of the accompanying thought process. Extensions and generalizations are given according to chronology: • P´olya-Eggenberger’s urn • Bernard Friedman’s urn • Generalized P´olya urns • Extended urn schemes • Invertible urn schemes ...

We examine the impact of orphanhood on children's school enrollment in 10 sub-Saharan African countries. Although poorer children in Africa are less likely to attend school, the lower enrollment of orphans is not accounted for solely by their poverty. We find that orphans are less likely to be enrolled than are nonorphans with whom they live. Consistent with Hamilton's rule, the theory that the...

This study examined the effects of parental monitoring in order to discover specific ways that their re1ationships with their parents affect ado1escents' delinquent behaviour. Data were taken from the National Survey of Youth 1972, a survey of a representative samp1e of 1395 Americans in the age range 11-18 years. Conditions such as the age and sex of the respondents, their affectiona1 re1ation...
