Design of S-band circularly polarized double-layer microstrip antenna

This paper proposes a compact polarization microstrip antenna based on double-layer structure.The bandwidth of the whole antenna is widened by expanding the top and bottom layers respectively.After the design of antenna structure and adjustment of size,the proposed antenna can achieve both the left-and right-hand circular polarizations in 2.33 GHz-2.97 GHz.Measurement results indicate that the effective bandwidth is 640 MHz in S-band and the relative bandwidth can achieve 24% with 11 S less than 15 dB.     

以能力结构为主线，构建应用型技术人才培养方案的探讨——以通信工程专业为例

就地方本科院校应用型人才培养模式改革进行了初步探讨,根据“三位一体”人才培养模式改革思路,构建了以能力培养为主线的人才培养新方案,打破了以知识逻辑关系构建课程体系的惯例。为实现各级能力培养子目标而设置相应的课程群,通过对课程群内课程内容的归类、整合、协调、选择与调整,使之形成能力脉络鲜明、清晰,能力结构合理的课程体系。新的人才培养方案较好地将理论教学、实验实训以及校园文化活动融为一体,是对学生能力培养的一次新的尝试。     

学校恐惧倾向儿童的情绪识别能力

本研究采用内隐联想测试来区分儿童是否具有学校恐惧倾向,进而考察他们的情绪识别能力.本研究采用内隐联想测试和学校恐惧分量表将儿童分组,并使用表情判断任务测试表情识别能力.结果表明,使用内隐联想测验分组的儿童在学校恐惧分量表的得分上有显著差异.具有学校恐惧倾向的儿童对恐惧表情的识别正确率显著低于普通儿童,对悲伤面孔的反应时也显著长于普通儿童.因此可以得出如下结论:学校恐惧倾向儿童在表情识别上与普通儿童存在差异.     

文化因素对大学英语议论文写作的影响———基于非英语专业本科生的实证研究

汉语思维模式极易在英语议论文写作时构成干扰因素,产生负面影响,以至造成文章汉语思维,英文表达.文章对165名非英语专业大学一年级本科生所写的英语议论文的文化影响进行了统计和分析.在统计中发现学生在词汇、句法和语篇层面都受到文化因素的影响,从而认为议论文写作教学不仅要重视词汇和语法,更应该强调思维模式上的差异.     

二阶线性微分方程的振动性质

研究了一般形式的二阶线性微分方程x″(t)+p(t)x′(t)+q(t)x(t)=0的振动性质,得到了这类微分方程振动的准则,从而推广了文献[1]的结果.     

“罗生门”历史发展中的语意指象差异性解析

从物语中的三则故事,到芥川小说演化为两篇小说,再到黑泽明拍摄成一部电影,"罗生门"的意义指象经历了一个脱胎换骨的演变过程。在这一过程中,不同作品的相同精神决定了它始终能焕发出无尽的活力,而其精神差异又是它在新的时代中不断被接受的根源。

“怪诞”与“怪”

我国美学怪诞泛化的主要表现,是将中国文论中的"怪"当grottesco怪诞。怪诞是恶与滑稽按反常化方式构成的、既可怕又好笑的系统结构模式审美形态。怪是以反常化方式构成的、能使人惊异的一切对象。怪诞的构成成分是恶与滑稽,怪既可以是真善美也可以是假恶丑。怪诞的构成方式是反常化,怪是在常有、现实的反方向上制造陌生、超现实,本质上也是反常化。怪诞的接受反应是可怕与好笑的混杂,怪只是惊。     

The impact of an online intervention (Brainology) on the mindset and resiliency of secondary school pupils: a preliminary mixed methods study

This preliminary study investigated the impact of the online interactive programme Brainology (which aimed to encourage a growth mindset) on the mindset, resiliency and sense of mastery of secondary school pupils. A quasi-experimental pre-, post- and follow-up mixed-methods study was carried out with 33 participants aged 13–14?years. The measures were Dweck’s theories of intelligence scale and Prince-Embury’s resiliency scales for children and adolescents. Quantitative data were analysed using analysis of variance. Qualitative data from focus groups were categorised and coded. The programme led to a significant increase in pre- to post-mindset scores for the intervention group. However, there was a significant decline at follow-up and the initial impact of the intervention was not sustained. There were no significant changes in mindset for the comparison group. There were no significant changes in resiliency or sense of mastery for either group. The significant short-term impact of Brainology and non-significant follow-up findings are discussed. The present study has limitations such as small sample size, which has implications for generalisability. Future research should investigate the longer term effectiveness of educational interventions in schools.

Trainee Change through Teacher Training: A case study in training English language teachers in Spain

In the course of giving greater importance to trainees' previous knowledge about and experience of teaching and learning foreign languages, the role of teacher training courses as agents of change has recently been questioned. Through a research project reported in this article I tried to find out to what extent two teacher training courses I was recently involved in caused trainees to change their points of view in relation to some of the fundamental issues involved in teaching. Special attention was given to the sources of these modifications, particularly to the role that teaching practice plays in them.
