Examining Ecological Constraints on the Intergenerational Transmission of Attachment Via Individual Participant Data Metaâanalysis
Parentsâ attachment representations and childâparent attachment have been shown to be associated, but these associations vary across populations (Verhage et al., 2016). The current study examined whether ecological factors may explain variability in the strength of intergenerational transmission of attachment, using individual participant data (IPD) metaâanalysis. Analyses on 4,396 parentâchild dyads (58 studies, child age 11â96 months) revealed a combined effect size of r = .29. IPD metaâanalyses revealed that effect sizes for the transmission of autonomousâsecure representations to secure attachments were weaker under risk conditions and weaker in adolescent parentâchild dyads, whereas transmission was stronger for older children. Findings support the ecological constraints hypothesis on attachment transmission. Implications for attachment theory and the use of IPD metaâanalysis are discussed
THE PROCESSES OF CHLORATING, THE STRUCTURE AND PROPERTIES OF THE CHLORATED POLYOLEPHINES AND COMPOSITION MATERIALS ON ITS BASE
The processes have been studied and the mechanisms of chlorating the polyolefines - PEVD, PEND, SCEP, SCEPT, PP, polybuten-1, poly-4-methylpenten-1 and polyvinylcyclohexane in the solution, in the suspension and in the solid phase. For the first time, the new polymers (CPO) with the properties of plastics, thermoelastoplasts, elastomers, skin-similar, frigid polymers, resines have been synthesized by the polyolefines chlorating. On the base of the CPO, the new high-effective corrosion-, thermo-, fire-proof PCM have been developed, the workshop has been built, the production of the PCM, grades BS-47, B-850 and TZR has been organized.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
