关于凸函数的推广

本文用变动上限积分构造一类函数,得到如下主要结果:1 它具有类似于凸函数的性质.2 对闭区间〔a,b〕上定义的任一凸函数F_*(X),总能表示成F_*(x)=F(x)+C,x∈〔a+ε,b-ε.〕,其中F(x)就是本文中所定义的一个函数,C为常数,ε为任意正数,从而得到了一类推广的凸函数.并给出了这类函数的一些应用.

A pedagogical alliance for academic achievement: Socio-Emotional effects on assessment outcomes

Assessment of student learning outcomes is often discussed in relation to curriculum, standards and even administration practices. However, assessment of learning outcomes is rarely discussed in light of students’ socio-emotional contexts, which might help or hinder learning outcomes. For example, do students’ perceptions of the teacher as trustworthy influence their empathic views on classmates, learning engagement, academic achievement and wellbeing? The present paper reports the results of a theoretically-driven, short-term longitudinal study designed to explore the effects of socio-emotional variables, specifically students’ trust in teachers and empathy towards self and peers on engagement for learning, academic achievement, and wellbeing. Grounded in attachment theory and the LEAFF model, Panel Structural Equation Modeling (P-SEM) results revealed three significant pathways, which provide evidence that student trust in teachers may serve to launch a domino effect of outcomes, predicting students’ empathic views of classmates, learning engagement, academic achievement, and wellbeing.

bmo-miR-0001 and bmo-miR-0015 down-regulate expression of <Emphasis Type="Italic">Bombyx mori</Emphasis> fibroin light chain gene in vitro

Based on bioinformatic analysis, we selected two novel microRNAs (miRNAs), bmo-miR-0001 and bmomiR-0015, from high-throughput sequencing of the Bombyx mori larval posterior silk gland (PSG). Firstly, we examined the expression of bmo-miR-0001 and bmo-miR-0015 in 12 different tissues of the 5th instar Day-3 larvae of the silkworm. The results showed that the expression levels of both bmo-miR-0001 and bmo-miR-0015 were obviously higher in the PSG than in other tissues, implying there is a spatio-temporal condition for bmo-miR-0001 and bmo-miR-0015 to regulate the expression of BmFib-L. To test this hypothesis, we constructed pri-bmo-miR-0001 expressing the plasmid pcDNA3.0 [ie1-egfp-pri-bmo-miR-0001-SV40] and pri-bmo-miR-0015 expressing the plasmid pcDNA3.0 [ie1-egfp-pribmo-miR-0015-SV40]. Finally, the BmN cells were harvested and luciferase activity was detected. The results showed that luciferase activity was reduced significantly (P<0.05) in BmN cells co-transfected by pcDNA3.0 [ie1-egfp-pri-bmomiR-0001-SV40] or pcDNA3.0 [ie1-egfp-pri-bmo-miR-0015-SV40] with pGL3.0 [A3-luc-Fib-L-3′UTR-SV40], suggesting that both bmo-miR-0001 and bmo-miR-0015 can down-regulate the expression of BmFib-L in vitro.
