面心立方和亚稳液相Au的原子状态及物理性质与温度变化关系的Debye-Grüneisen模型研究

结合纯金属单原子(OA)理论和Debye-Grüneisen模型研究了SGTE纯单质数据库中面心立方和亚稳液相Au的原子状态、原子势能、原子动能、原子体积、体弹性模量和热膨胀系数等物理性质随温度的变化关系,结果表明:电子结构计算结果与第一原理方法一致;原子的单键半径随温度升高而增大;原子动能随温度升高明显增大,并且其速率是原子势能的4倍多;体弹性模量随温度升高而缓慢下降;线热膨胀系数随温度的变化规律与实验值吻合较好。固体向液相转变时,共价d电子减少27.4%,共价s电子增加152%,自由s电子减小88.5%,非键电子数目增加近23%,使得原子的配位方向性减弱,自由度增大;电子结构的转变是导致原子单键半径增大和体积增加及其他物理性质发生改变的根本原因。

Value of information, behavioral guidelines, and social value orientation in an information-exchange dilemma.

Many situations of information exchange represent a social dilemma, in which individual costs and benefits for contributing information are contradictory to the group's costs and benefits. Recent studies have shown that (a) people select their contributions according to the benefit that these contributions provide to others, (b) the social value orientation of individuals affects their willingness to contribute, and (c) externally provided behavioral guidelines have an impact on individual behavior. We conducted 2 experiments in which people were able to actively manipulate the value that their information had for others (in Study 1, this value had no influence on their own costs; in Study 2, a higher value to others implied higher contribution costs for the individual contributor). Both studies revealed that people avoided contributing such information that would have provided others with a higher benefit than the benefit the individual contributors themselves received through this information. Even prosocials—who generally acted more cooperatively than proselfs—behaved like that. In both studies, behavioral guidelines had an impact on the number of contributions, independent of the value of information. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Value transmissions between fathers, mothers, and adolescent and emerging adult children: The role of the family climate.

Using structural equation modeling, this study investigates father–child, mother–child, and father–mother transmissions on “work-as-duty” and “hedonism” across a 5-year period when children traverse late adolescence and emerging adulthood (N = 402 families). We found bidirectional father–child and child-to-mother transmissions on work-as-duty and child-to-father and bidirectional father–mother transmissions on hedonism. In addition, we examined whether family adaptability and cohesion influence these value transmissions. Father-to-child transmission on work-as-duty occurred regardless of family system levels, whereas child-to-parent transmissions on work-as-duty occurred only within more structured families. Furthermore, a more connected family climate tended to facilitate inter- and intragenerational value transmissions, but multiple-group analyses did not reveal strong evidence. All in all, this study showed that value socialization in the family is not a one-way-traffic process with parents solely influencing their children. Late adolescents and emerging adults also serve to socialize their parents and parents socialize each other. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
