股票的内在价值与投机价值

股票投机价值由股票特有的预期性和虚拟性以及由此而发生的股市供求关系的盲目性等属性所决定,并由股票内在价值和市场供求状况的合力形成。文章在确定股票投机价值内涵的基础上,进一步讨论了投机价值的确定性和不确定性以及它与内在价值、市场价格和风险的关系,并界定了投机利润的来源。

区熔硅单晶的红外吸收差谱测量

通过红外光谱测量,研究了原生区熔硅单晶、中子辐照区熔硅单晶以及热处理后的中子辐照区熔硅单晶的中心部位与边缘部位之间的红外吸收差谱．根据这些红外吸收谱,讨论了区熔硅单晶中替位式杂质碳、间隙式杂质氧的径向分布以及中子辐照、热处理温度对它们的影响．用四探针法测量了中子辐照区熔硅单晶的电阻率随退火温度的变化关系．     

Seeing The World Through Rose‐colored Glasses? Neglect of Consensus Information in Young Children's Personality Judgments

The present study examined the use of consensus information in early childhood. Ninety‐six three‐ to six‐year‐olds watched a demonstration that depicted the positive or negative behavior of one or several actors toward a recipient (low vs. high consensus, respectively). Subsequently, participants made behavioral predictions and personality judgments about the actors and recipients. Participants viewed all story characters favorably and were reluctant to assign blame for negative outcomes, although the appropriate use of consensus information increased with age for behavioral predictions. These findings suggest that there is a positivity bias in young children's personality judgments even in the face of explicit contradictory behavioral evidence. Children's early ‘theory of personality’ is apparently driven by a baseline assumption that people are nice.     

Interracial‐Interethnic Unions and Fertility in the United States

How does the fertility of interracial and interethnic couples compare to the fertility of endogamous couples? If exogamous couples have transcended the boundary between them, then exogamy should not affect fertility. Alternatively, opposition to the relationship from the couple’s family and friends may reduce fertility. This study uses 2000 – 2005 American Community Survey data on married (n = 272,336) and cohabiting (n = 48,769) couples to compare the fertility of endogamous and exogamous couples. Interracial and interethnic partnering do not affect fertility for cohabiting, Black‐White, Mexican‐White, and Puerto Rican‐White intermarried couples, but it does reduce fertility in Chinese‐White and Asian Indian‐White intermarriages. These results are largely consistent with the argument that intermarried couples have transcended group boundaries.
