高脂血症病人血液流变学指标的测定

本文对９７例健康人与４４例高脂血症病人进行血液流变学等１０项指标的测定与比较，实验结果证明，高脂血症病人的全血粘度（２３０．００ｓ＾－１，２３．００ｓ＾－１，９．６０ｓ＾－１），血浆粘度（２３０．００ｓ＾－１），纤维蛋白原等均明显高于健康人，经统计学处理（Ｐ＜０．０１），有显著差异。

激光三角法测量的误差研究

激光三角法测量是三维曲面非接触测量的主要方法之一，但测量精度受到本身结构和被测物体特性及环境因素等多方面的影响。本文简要介绍了激光三角法测量的原理，通过对一种型号的激光位移传感器的实验，对激光三角法测距由于被测物体表面特性不同和变化所引起的误盖进行了全面地分析和研究，井针对不同误差原因提出了改进的方法。     

电子商务中基于深度学习的虚假交易识别研究

为了解决电子商务平台中存在的虚假交易问题,本文依据商品的销售记录以及商家的基本信息,提出了一种结合深度置信网络和多层感知器的虚假交易识别方法,通过识别出以通过刷单增加销量的商品来识别虚假交易。首先利用深度置信网络对交易特征进行学习,得到更高层次的抽象特征;然后利用多层感知器进行分类任务,从而识别出虚假交易。从淘宝中爬取商品的交易记录和评论数据进行实验验证,与其他机器学习模型的实验结果进行对比,其性能有明显的提升。

The multidimensionality of multicultural service learning: The variable effects of social identity, context and pedagogy on pre-service teachers’ learning

Multicultural service learning (MSL) seeks to develop pre-service teachers’ capacities and commitment to teach diverse student populations. We use multiple regression analyses of survey data collected from 212 pre-service teachers engaged in 22 MSL sites to assess the effects of pre-service teachers’ social identities, MSL contexts, and university pedagogy on pre-service teachers’ awareness of cultural bias, understanding of social inequality, and commitment to teaching diverse students. We find that pedagogical engagement positively contributes to all three outcomes. Pre-service teacher’s social identities and MSL contextual factors, however, have variable effects. We explore the pedagogical and research implications of this multidimensionality.     

赵嘏、杜牧卒年与《唐诗类选后序》作年考论

有学者认为<唐诗类选后序>撰于"咸通元、二年间"或"咸通三年前后",并据此和其他"根据"考订赵嘏卒于大中十二三年,否定杜牧卒于大中六年.经过分析考证,张祜卒于大中八年,杜牧则卒于大中六年底,且顾陶前后两序之撰写时间极为接近,均是大中十年先后所撰,因此赵嘏即约卒于大中八年.     

Mother–child joint writing in Chinese kindergarteners: metalinguistic awareness,maternal mediation and literacy acquisition

The present study examined the relations of Chinese word reading and writing to both maternal mediation of writing and a number of metalinguistic and cognitive skills in 63 Hong Kong Chinese kindergarteners. The whole process of maternal mediation of writing, in which mothers individually facilitated their children's writing of 12 two‐character words in their own ways, was videotaped. This study replicated and extended previous work on the cognitive strategies mothers use to help children in writing Chinese words. Mothers' typical mediation strategies were positively and significantly associated with both children's independent word reading and writing. In addition, maternal mediation of writing was uniquely associated with Chinese word reading, but not word writing, even with metalinguistic and cognitive skills, including phonological awareness, morphological awareness, orthographic processing and visual knowledge, statistically controlled. Findings underscore the importance of mothers' early scaffolding in facilitating children's literacy acquisition.
