The functions of freezing in the social interactions of juvenile high‐ and low‐aggressive mice

Selectively bred low‐aggressive mice are frequently observed to freeze on social contact, despite the fact that this behavior was never a direct target of selection. To elucidate this finding, the present research aimed to identify the possible functions freezing may serve in social interactions. It was hypothesized that freezing may modify social interactions through self‐regulatory mechanisms and/or via its modulating effects on the actions of social partners. These hypotheses were evaluated with respect to the sequential changes observed over the course of a 10‐min dyadic test in freezing, social reactivity, and approaches among juvenile (24–30‐day‐old) mice from the NC900 and NC100 high‐ and low‐aggressive lines. Analyses of the patterns of social interactions between subjects and partners revealed two primary results. First, freezing was more than an expression of fear; it also functioned as a regulator of emotional arousal, as suggested by the substantial reduction of reactive behaviors seen in animals that showed high levels of freezing. Second, freezing functioned to facilitate high levels of affiliative social interaction with social partners. The implications of these results for understanding how the differentiation of the NC900 and NC100 occurred within microevolution and development are discussed. Aggr.

人才伦理学刍议

人才伦理是使人才之所以成为人才的各种伦理要素的总和;人才伦理既是人力资源管理理论的重要内容,也是伦理学特别是人才伦理学的研究对象。人才伦理学的内容主要包括以下五个方面：德与才的关系、人才的道德素质、人才的道德标准、人才的道德环境、人才的道德作用。德与才的关系是人才伦理学所要处理的基本关系,“德才兼备”是人才伦理学的核心范畴。提高人才的道德素质,是人才伦理学所确立的最高目标。人才伦理研究要揭示各类人才在道德要求和道德素质上的共同性和特殊性,为新世纪新阶段我国人才培养工作确立新的人才伦理原则和道德标准。     

Emotional availability and psychosocial correlates among mothers in substance‐abuse treatment and their young infants

Emotional availability (EA) was investigated among low‐income mothers enrolled in substance‐abuse treatment and their young infants (n = 21) compared with a demographically matched group of mother–infant pairs who, by self‐report, were not at risk for substance abuse (n = 27). The mother–infant dyads in the treatment group generally demonstrated poorer EA functioning than those in the comparison group, but few differences between the groups on individual dimensions of EA were significant. This finding was notable considering that mothers in treatment reported significantly higher levels of depressive symptoms and psychological stress. Treatment effects may have buffered the negative impact of depression and psychological stress on mothers' EA scores. The clinical implications of the findings are discussed as they relate to substance‐abuse‐treatment services for pregnant and parenting women.     

Gratuity,Embodiment, and Reciprocity

Protestant Christian ethicist Timothy Jackson and secular feminist philosopher Eva Feder Kittay each explore the relationship between love or care and justice through the lens of human dependency. Jackson sharply prioritizes agape over justice, whereas Kittay articulates a more complex and integrated understanding of the relationship of care and distributive justice. An account of Christian love and its relation to justice must account for the gratuity, mutuality, and reciprocity that pervade human existence. Such an account must integrate provision for another's basic needs, a feature of agape, with a distributive justice that fairly allocates the material prerequisites of care and the burden of caring labor. Kittay's treatment of care and justice is more adequate to the realities of human embodiment and the social organization of care than Jackson's, but neither offers a fully adequate ground for the moral personhood of all human beings, including deeply dependent persons.
