Intergenerational Effects of Parents’ Math Anxiety on Children’s Math Achievement and Anxiety

Abstract: A large field study of children in first and second grade explored how parents’ anxiety about math relates to their children’s math achievement. The goal of the study was to better understand why some students perform worse in math than others. We tested whether parents’ math anxiety predicts their children’s math achievement across the school year. We found that when parents are more math anxious, their children learn significantly less math over the school year and have more math anxiety by the school year’s end—but only if math-anxious parents report providing frequent help with math homework. Notably, when parents reported helping with math homework less often, children’s math achievement and attitudes were not related to parents’ math anxiety. Parents’ math anxiety did not predict children’s reading achievement, which suggests that the effects of parents’ math anxiety are specific to children’s math achievement. These findings provide evidence of a mechanism for intergenerational transmission of low math achievement and high math anxiety.

Disruption of Imprinted Gene Methylation and Expression in Cloned Preimplantation Stage Mouse Embryos

Abstract: Cloning by somatic cell nuclear transfer requires that epigenetic information possessed by the donor nucleus be reprogrammed to an embryonic state. Little is known, however, about this remodeling process, including when it occurs, its efficiency, and how well epigenetic markings characteristic of normal development are maintained. Examining the fate of epigenetic information associated with imprinted genes during clonal development offers one means of addressing these questions. We examined transcript abundance, allele specificity of imprinted gene expression, and parental allele-specific DNA methylation in cloned mouse blastocysts. Striking disruptions were seen in total transcript abundance and allele specificity of expression for five imprinted genes. Only 4% of clones recapitulated a blastocyst mode of expression for all five genes. Cloned embryos also exhibited extensive loss of allele-specific DNA methylation at the imprinting control regions of the H19 and Snprn genes. Thus, epigenetic errors arise very early in clonal development in the majority of embryos, indicating that reprogramming is inefficient and that some epigenetic information may be lost.

The Red Queen Effect: Competitive Actions And Firm Performance

Abstract: We investigate the Red Queen effect as a contest of competitive moves or actions among rivalrous firms. The results from a multi-industry study of over 4,700 actions confirms the existence of Red Q...

TESOL and Culture

Abstract: Culture is a central yet underexamined concept in TESOL. In comparison to other fields such as anthropology and cultural studies, there has been little serious discussion and critique of the concept in TESOL over the last two decades. This article offers a reassessment of the notion of culture in TESOL, taking recent work in critical anthropology and cultural studies, and to a lesser degree TESOL itself, as a starting point. It proposes a revised view of culture that is intended to serve TESOL practitioners into the 21st century, or that can at least provide a takeoff point from which such a view may be developed.
