浅析抗日战争中两个战场的相互关系

以国共合作为基础的抗日民族统一战线,是中国人民取得抗日战争胜利的基本条件。在抗日战争中由国民党领导的正面战场和由共产党领导的敌后游击战场,一直保持着既相对独立又相互配合的关系。两个战场相对独立的关系,主要表现为国共两党独立指挥所属武装力量,按照各自政党所确定的抗战路线、军事战略及作战原则实施作战。两个战场在保持相对独立关系的同时,还始终保持着相互配合的关系,这种相互配合,主要表现为战略配合,也有战役、战斗的配合。然而,各个层次的相互配合,有积极主动的配合,也有消极客观上的配合。

Maternal Frontal EEG Asymmetry and Chronic Stressors Moderate the Link between Child Conduct Problems and Maternal Negativity

Frontal electroencephalographic (EEG) asymmetry is associated with individual differences in positive/negative emotionality and approach/avoidance tendencies. The current study examined the moderating role of maternal resting frontal EEG asymmetry on the link between child behavior problems and maternal harsh parenting within the context of differing degrees of chronic family stressors (father unemployment, single parenthood, caring for multiple children, and household chaos). The sample included 121 mother–child pairs. Results showed that stressors and frontal EEG asymmetry together moderated the link. Child problem behaviors were moderately associated with greater maternal negativity for mothers with right frontal asymmetry, or mothers who experienced more stressors. However, no association existed between child behavior problems and maternal negativity for mothers with few stressors and left frontal asymmetry. The findings implicate transactions between household stress and a psychophysiological indicator of maternal emotional reactivity and mothers' approach/avoidance tendencies in the etiology of parental negativity toward challenging child behaviors.
