《进入黑夜的漫长旅程》的节奏分析

尤金·奥尼尔是现代美国戏剧的缔造者,他晚期创作的具有极强自传色彩的《进入黑夜的漫长旅程》被公认为是他的巅峰之作。该剧之所以能够获得巨大成功,原因很多,而奥尼尔为其构建的精巧的富于变化的节奏模式也是重要因素之一。本文试图从作品所包含的几种要素——情节、语言策略、角色的态度和身体语言以及场景的变化等角度详细解析剧本的戏剧节奏,以期证明戏剧节奏不仅是作品结构的重要表现,而且是剧作家用以制造特殊戏剧效果的一件不可或缺的带有其个人特色的创作工具,并能对探讨奥尼尔戏剧作品的节奏起到抛砖引玉的作用。

When Corporate Social Responsibility Messages Enter the News: Examining the Effects of CSR-Framed News on Product Purchasing Intentions and the Mediating Role of Company and Product Attitudes

Journalists are frequently reporting about new and innovative products in news articles. Oftentimes, journalists use specific company and product information provided by enterprises that highlight a corporation’s social responsibility (CSR) activities. Based on framing theory and theory of reasoned action, an experiment was conducted to examine how types of CSR-framed news (either highlighting ethical, ecological, or philanthropic responsibilities of a company) affect news recipients’ product purchasing intentions. A mediation analysis showed that CSR-framed news indirectly and positively affected individuals’ purchasing intentions via company and product attitudes. No relevant differences could be detected for the specific type of CSR frame. Implications of the results are discussed.     

浅析健美操训练对跳高选手的作用

健美操具有音乐、体育、舞蹈、美学的多种社会功能,对跳高选手的作用表现在:发展肌群力量,改善柔韧性;能诱导学生学习和掌握正确的基本技术和技能,激发学习兴趣;改善协调性,培养节奏感,促进训练后疲劳的恢复。但训练时一定要有针对性,内容不宜过多,时间不宜过长。     

实现数字校园协同效应的八种作用机制

数字校园在协同机制的作用下产生协同效应是数字校园实践者和研究者所期待的理想目标。数字校园协同效应的实现依赖于数字校园领导机制、保障机制、激励机制、安全机制、管理机制、资源共享机制、评估机制和服务机制等8种作用机制的相互影响、相互作用。北京市属8所普通本科高校、5所高职院校、38所中小学数字校园建设调查显示：这8种机制在不同学校的受重视程度、发展现状、运行方式等有很大差异,但总体上发展都不够完善,亟需提高认识,不断改进。因此,在数字校园建设过程中,应该充分重视这8种作用机制的功能、作用和相互关系,采取有效措施完善这些机制,促使数字校园产生协同效应,实现价值最大化。     

Question classification using limited labelled data

Question classification (QC) involves classifying given question based on the expected answer type and is an important task in the Question Answering(QA) system. Existing approaches for question classification use full training dataset to fine-tune the models. It is expensive and requires more time to develop labelled datasets in huge size. Hence, there is a need to develop approaches that can achieve comparable or state of the art performance using limited training instances. In this paper, we propose an approach that uses data augmentation as a tool to generate additional training instances. We evaluate our proposed approach on two question classification datasets namely TREC and ICHI datasets. Experimental results show that our proposed approach reduces the requirement of labelled instances (a) up to 81.7% and achieves new state of the art accuracy of 98.11 on TREC dataset and (b) up to 75% and achieves 67.9 on ICHI dataset.     

Psychological Reactions to Crime News Portrayals of Black Criminals: Understanding the Moderating Roles of Prior News Viewing and Stereotype Endorsement

An experiment examined the extent to which viewers’ death penalty application, perceptions of crime danger, and culpability assessments could be influenced by exposure to a majority of Black suspects in the news or having the race of suspects go unidentified in a newscast. The current study also investigated the extent to which prior news viewing and African American stereotype endorsement might moderate the effects of this racialized crime news exposure. After exposure to a majority of Black suspects or unidentified suspects in a newscast, African American stereotype endorsers were more likely than stereotype rejecters to support the death penalty. Furthermore, heavy television news viewers exposed to a majority of Black suspects were more likely than light news viewers to perceive the world as dangerous and view a race-unidentified suspect as culpable for his offense. The theoretical implications of these findings are discussed in light of social cognition theories of priming, cognitive accessibility, stereotype activation and application.     

The National Curriculum balance sheet for Key Stage 2: a researcher's view

The National Curriculum had very specific objectives. From the beginning there have been claims that the failure to implement the programme in full was the fault of a ‘liberal’ educational establishment. This article looks at implementation from the perspective of a researcher who was engaged in classroom observation, mainly in primary schools, during the late 1980s and early 1990s. Among the consequences of the implementation strategies adopted have been negligible effects on teaching methods, falling standards and lack of increased curriculum continuity on transfer to Key Stage 3. The findings of this research suggest that recent calls for teachers to be mandated as to how to teach the curriculum will not overcome these problems.     

结合语音训练的伙伴背诵对英语学习的影响

作为一种重复接触语言材料的学习方式,背诵能够有效提高语言能力。背诵不仅有其深厚的心理语言学和语言学习理论基础和意义,其益处也已得到实践的证明。笔者针对目前背诵实践中的缺陷,采用结合语音训练的伙伴背诵模式,强化背诵式输入的质量。实验结果表明,结合语音训练的伙伴背诵模式有利于提高学习者的口语和写作水平,增强自信心和学习兴趣,进而影响学习者的学习动机。
