The purpose of the study was to investigate the link between sibling relationships and antisocial behavior in 208 boys from low-income families. Sibling relational attributes and mother-target child (MTC) relationship quality were assessed when the target child (TC) was 10 years old. At ages 11 and 12, TC antisocial behavior and TC reports of peer antisocial behavior were evaluated. Results ind...

Sibling interactions in old age have received limited attention in social science literature. This article examines the different kinds of relationships which exist between siblings in old age and the ways in which each type meets or ignores the social and psychological needs of older people. Five types of sibling relationships emerged from data collected in open-ended, exploratory interviews w...

This study investigated the prospective links between sibling aggression and the development of externalizing problems using a multilevel modeling approach with a genetically sensitive design. The sample consisted of 780 adolescents (390 sibling pairs) who participated in 2 waves of the Nonshared Environment in Adolescent Development project. Sibling pairs with varying degree of genetic related...

When siblings differ markedly in their need for food, they may benefit from signalling to each other their willingness to contest the next indivisible food item delivered by the parents. This sib–sib communication system, referred to as ‘sibling negotiation’, may allow them to adjust optimally to investment in begging. Using barn owl (Tyto alba) broods, I assessed the role of within-brood age h...

This study examines the use of codominant restriction fragment length polymorphism (RFLP) markers to estimate the number of sibling families found within and among oviposition sites used by the mosquito Aedes aegypti (L) (Diptera: Culicidae). Estimates were made using pairwise relatedness (rxy) calculations based on alleles shared between individuals. Genotypes for eight laboratory mosquito fam...

The kin term product calculations used by culture-bearers to compute kin relationships from kin terms without reference to genealogy are the basis for the structure of a kinship terminology and its underlying generative logic. The details of that logic account for differences in the structural forms for kinship terminologies. The structural form of the Polynesian kinship terminologies, like tha...
