TL;DR: Wang et al. as discussed by the authors showed that the verticalization of family structure has changed the support between aging parents and adult children among middle-aged adults who are often in the position of providin...

TL;DR: A population genetic model is developed to investigate the effect of recombination between mean- and variance-modifiers of phenotype on the geometric mean principle under different environmental regimes and fitness landscapes and shows that interactions of recombinations with stochastic epigenetic variation and environmental fluctuations can give rise to complex evolutionary dynamics that differ from those in systems with no recombination.

TL;DR: In this article, an index of dependence on ecosystem services (IDES) was constructed to evaluate the dependence of households' net income generation on ecosystem service, and the effects of the relocation and settlement program on rural households' IDES were examined.

TL;DR: In this article, a multilevel survey of rural Chinese families reveals three categories of perceived resilience in families: perceived optimistic families, perceived cooperative families, and perceived pessimistic families, including natural, social, financial, and human capitals.

TL;DR: A dichotomous phenotype whose transmission from parents to offspring depends on the parents’ phenotypes and the offspring’s genotype is studied and it is shown that the frequency of alleles at genes affecting the phenotypes strongly affects standard heritability measures.
