• The notion of authority is common in the literature on parent-child relationships. However, the notion of ‘parental authority’ remains largely unspecified. The present article first critically reviews conceptualisations of parental authority in selected developmental-psychological approaches. We find the absence of an explicit and integrated theoretical and empirical conceptualisation of pare...

This study examines the relationships between parental assets with their expectations and involvement of children’s education, and children’s educational performance measured 2 years later. Through the analysis of the mother–child data set of the National Longitudinal Survey of Youth (NLSY79), results indicate that after controlling for family income and other parent characteristics, parental a...

Natural hybrid zones have proven to be precious tools for understanding the origin and maintenance of reproductive isolation (RI) and therefore species. Most available genomic studies of hybrid zones using whole- or partial-genome resequencing approaches have focused on comparisons of the parental source populations involved in genome admixture, rather than exploring fine-scale patterns of chro...

Abstract. Self-similarity of random trees is related to the operation of pruning. Pruning R cuts the leaves and their parental edges and removes the resulting chains of degree-two nodes from a finite tree. A Horton-Strahler order of a vertex v and its parental edge is defined as the minimal number of prunings necessary to eliminate the subtree rooted at v. A branch is a group of neighboring ver...

Examination of microsatellite variation at several polymorphic loci is a widely accepted method for determining parentage and examining genetic diversity within rainbow trout (Oncorhynchus mykiss) breeding programs. Genotyping costs are considerable; therefore, I developed a singlestep method of co-amplifying twelve microsatellites in two hexaplex reactions to reduce costs and improve efficienc...

This study assessed the impact of Pinus radiata (D. Don) genetically modified (GM) by biolistic insertion of the LEAFY and nptII genes on rhizosphere microbial communities of field grown trees. Rhizosphere soil was sampled quarterly for two consecutive years. A culture-independent approach was used to characterise the microbial communities based on PCR and denaturing gradient gel electrophoresi...

Two prominent mangrove species of Fiji, Rhizophora mangle, Linn. Rhizophora stylosa Griff and their puative hyubrid (R x selala) were analysed for chromosome number and pairing. Both parental species and their hybrid possess a diploid number of (2n) = 36 chromosomes. Regular 18 bivalents were observed in two species but the hybrid lacked proper chromosome pairing during meiosis. Analysis of tet...

Although hybridization in plants has been recognized as an important pathway in plant speciation, it may also affect the ecology and evolution of associated communities. Cottonwood species (Populus angustifolia and P. fremontii) and their naturally occurring hybrids are known to support different plant, animal, and microbial communities, but no studies have examined community structure within t...
