论贾谊对儒家思想的继承和发展

在我国历史上,英年早逝而能赢得“汉初著名政论家、思想家、文学家”之称的贾谊,是位不多见的人物。观其创作,贾谊在民本思想、“仁”的思想、教育思想等几个方面都对儒家思想有所继承和发展,为董仲舒建立新的儒学体系打下了良好基础。贾谊是促成儒学思想成为国学思想的第一奠基人。

Preschool children use linguistic form class and pragmatic cues to interpret generics

Generic noun phrases (e.g., "Bats live in caves") are important for expressing knowledge about abstract kinds. Past work has found that parents frequently use generic noun phrases in their speech to young children. However, little is known regarding how children understand these expressions, nor which cues signal generic meaning. The present set of 5 studies examined the influence of linguistic form class (e.g., "What color are dogs?" [generic] versus "What color are the dogs?" [nongeneric]) and of pragmatic context (e.g., "What color are they?" in the presence of either a single exemplar [generic] or multiple exemplars [nongeneric]). Participants were 2-year-olds (N = 42), 3-year-olds (N = 40), 4-year-olds (N = 40), and adults (N = 51). The data indicate that by 2 years of age, children use linguistic form class, and by 3 years of age, children use pragmatic context. These findings demonstrate that young children have begun to understand the distinction between generic and nongeneric noun phrases from a very young age, and that identification of generics is signaled not by formal or pragmatic cues alone, but by a combination of information from both language form and pragmatic context. It is suggested that children make use of multiple linguistic and conceptual cues to acquire and interpret generics.

Prenatal parenthood

In this article, we discuss the intuitive knowledge mothers have of their unborn baby. We propose a shift in focus from caregivers' merely providing information to first listening to pregnant mothers as they share their intuitive knowledge of their baby. This approach enables mothers and fathers or partners to know they are already parents to their unborn baby and empowers them to get in touch with their baby's presence and who he or she is during pregnancy. This intuitive knowledge may be a protective behavior that will enable mothers to keep babies safe during pregnancy.     

Attributions and Attitudes of Mothers and Fathers in China

OBJECTIVE: The present study examined mothers' and fathers' attributions and attitudes related to parenting in China. DESIGN: Interviews were conducted with 241 pairs of parents to obtain maternal and paternal reports of attributions regarding successes and failures in parent-child interactions and on progressive versus authoritarian attitudes about parenting. RESULTS: Mothers' mean levels of attributions and attitudes did not differ significantly from fathers' mean levels of attributions and attitudes. Significant correlations were found between mothers' and fathers' attributions regarding uncontrollable success, authoritarian attitudes, and modernity of attitudes. CONCLUSIONS: Supporting the cultural evolutionary view that drastic social changes bring about non-conforming and individualistic behavioral tendencies, these findings rectify and expand the existing literature portraying Chinese parenting as uniformly Confucian and traditional.
