Perceived Parental Influence on Mathematics Learning: A Comparison Among Students in China and Australia

This paper explores the perceived parental influence (PPI) on mathematics learning among over 700 students across three year levels (Years 5, 7, 9) in China and Australia. It was found that the PPI of students was less strong as year levels increased in both countries. Students in China had stronger perceived parental encouragement and higher perceived parental educational expectation than students in Australia. The PPI of students from different home language backgrounds was also investigated. Students in China demonstrated stronger perceived parental encouragement and parental expectation than English speaking students and other language speaking students in Australia, and they also demonstrated stronger perceived parental expectation than Chinese speaking students in Australia, and similar perceived parental encouragement. Within the three groups of students in Australia, Chinese speaking students and other language speaking students demonstrated similar levels of perceived parental encouragement and expectation, but they both demonstrated a higher level of perceived parental encouragement and expectation than English speaking students. Possible reasons for the similarities and differences between the different groups of students were discussed.     

兼语句与其他句式结构的区别－现代汉语特殊句式辨析之二

兼语句是现代汉语的一种特殊句式，对它的研究，早在王力的《中国现代语法》就已开始了，而且主要涉及到兼语句的结构特点及扩缩存废问题。本着重从兼语句的结构特征、语义特征与其他句式结构的比较中区别出这一句式的特征来。     

Why some teachers easily learn to use a new virtual learning environment: a technology acceptance perspective

After a decade of virtual learning environments (VLEs) in higher education, many teachers still use only a minimum of its affordances. This study looked at how academic staff interacted with a new and unknown VLE in order to understand how technology acceptance and support materials influence (perceived and actual) task performance. In an experimental design, 36 participants were split into a control (online help) and experimental (instructor video) condition and completed five common teaching tasks in a new VLE. In contrast to most technology acceptance model research, this study found that perceived usefulness of the VLE was not related to (perceived) task performance. Perceived ease of use was related to intentions and actual behaviour in the VLE. Furthermore, no significant difference was found between the two conditions, although the experimental condition led to a (marginal) increase in time to complete the tasks.     

花粉管通道法转基因对小麦主要农艺性状的影响

采用花粉管通道法介导外源耐盐基因SeNHX1导入4个小麦品种（品系）BN-64、YM-34、BM-1和AK-58中,并对转基因D0代的主要农艺性状进行了统计分析.结果表明,与对照相比,转基因D0代植株的种子（D1代）千粒重、株高、穗长、旗叶面积均有所提高;D0代植株与对照组相比,株高差异均达到显著水平,甚至极显著水平;穗长除BM-1差异不显著外,其余受体均达显著水平.叶面积差异均达到显著水平;叶长除YM-34外,其余受体差异均达到极显著水平.叶宽与受体相比均无明显差异.     

陆地棉F_2代单株选择的主成分分析

以抗虫棉品种和非抗虫棉杂交,在选择的条件下对F2代单株性状采用主成分分析的方法,就综合农艺性状对产量性状的影响进行了研究.结果表明：前5个主成分因子累积方差贡献率达74.95%,基本反映遗传信息.各主成分分析结果依次为：结铃性因子、形态因子、铃重因子、衣分因子、营养生长因子.依据主成分评价,较为理想的杂交F2代抗虫棉单株应是第1主成分较大,第2主成分适中的品种,即以果节数、果枝数和结铃数多,果枝夹角、株高和铃重适中的类型.通过5个主成分的总得分,构建出新的一个F2代单株选择指数,可以此作为F2代单株选择的依据.     

学习效能感在高中生班级环境与 学习动机间的中介效应

为考察高中生学习效能感在班级环境与学习动机间的中介效应,采用学习动机、学 习效能感和班级环境问卷调查403名高中生.结果表明:(1)女生威信动机高于男生;男生 学习效能感高于女生;师生关系一年级好于二年级,女生好于男生;(2)学习动机与师生关 系、竞争、基本能力感和控制感正相关;基本能力感与秩序纪律负相关,与同学关系和控制 感正相关;控制感除学习压力外,与班级环境其他维度正相关.(3)基本能力感在秩序纪律 和学习动机间具有中介作用,控制感在竞争和学习动机间具有中介效应.高中生学习动机 的激发与维持的关键是提高学生的学习效能感,适当的竞争环境与相对民主、自由的班级 氛围有利于学生学习效能感的提高.

浅析大五人格特质和社会群体地位的关系

个体的人格特质和他在社会群体中的地位存在一定的关系。人格大五的每一维度在个体获得社会地位中的作用不同。外倾性对个体的地位获得有很好的预测作用 ,而神经质则不利于个体获得社会地位 ;宜人性和社会地位之间的关系 ,目前尚无定论。在非正式社会群体中 ,个体的责任心、开放性和社会地位获得没有关系。     

高等教育顾客感知服务质量的实证研究

高等教育顾客感知服务质量是指高等教育服务的固有特性满足顾客明确的或潜在的要求的程度，它包括六个特性：有形性、形象性、过程性、内容性、情感性和可靠性。高等教育顾客感知服务质量比较显著地影响顾客满意感，并通过顾客满意感影响顾客行为意向。     

网上购物者购买决策过程的心理机制探析

近年来网上购物成为一种时尚,为满足不同层次的需要,消费者产生网上购物需求,这促使消费者去网上搜集产品信息,此时,注意、感知觉、情绪、记忆都会影响信息的搜集;接着人对林林总总的信息进行评价,当其感知风险低于可接受水平时,才会做出购买决策;然而又有很多心理因素影响决策甚至行为过程;最后消费者使用商品时会进一步评价该商品,这反过来会影响其新的购买需求的产生.
