子女数量与农村居民幸福感——基于性别和年龄差异视角

本文基于CGSS2013的调查数据,从子女数量与农村地区不同群体的幸福感关系视角,分析了中国农村地区子女数量对农村居民幸福感的影响。结果表明:(1)子女数量对农村居民幸福感呈现显著正向影响,有孩子的家庭相比无孩子的家庭更幸福,子女数量越多的家庭幸福感越高;(2)子女数量和农村男性群体的幸福感呈现显著正相关关系,而与女性群体幸福感的正相关关系则较为微弱;(3)子女数量可以显著提高农村老年人群体的幸福感,而对于中青年群体则会产生正向但不显著的影响。

Non-simultaneous Blow-up Criteria for Localized Parabolic Equations

This paper deals with blow-up solutions for parabolic equations coupled via localized exponential sources, subject to homogeneous Dirichlet boundary con- ditions. The criteria are proposed to identify simultaneous and non-simultaneous blow-up solutions. The related classification for the four nonlinear parameters in the model is optimal and complete.

Non-simultaneous quenching for a slow diffusion system coupled at the boundary

This paper deals with the quenching behavior of positive solutions to the Newton filtration equations coupled with boundary singularities.We determine quenching rates for non-simultaneous quenching at first,and then establish the criteria to identify the simultaneous and non-simultaneous quenching in terms of the parameters involved.
