电子游戏对青少年认识他国文化的作用和影响

随着互联网的快速发展,电子游戏已经成为一种重要的文化传播媒体。电子游戏中的文化元素对青少年了解其他民族和国家的文化是否具有重要的影响引起了学术界的广泛关注。日本游戏由于造型符合亚洲玩家的审美观,深受中国游戏玩家喜欢。通过对玩日本游戏的中国青少年进行案例分析、访谈和问卷调查发现：日本游戏中所呈现的民族服饰、生活方式、建筑风格、行为方式、故事情节等文化元素对中国青少年了解日本文化具有一定的积极作用,而游戏中的暴力、色情和恶搞等元素也对中国青少年的成长产生了一定的负面影响。但目前这些影响还很有限,绝大多数的青少年有一定的控制能力。     

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.

本文试图通过传播学原理和具体的事例论证大众传媒对竞技体育的深刻影响,这些影响不仅包括积极的影响,也包括了消极的影响。文章最后指出：大众传媒应通过自己的影响力,进一步促进竞技体育的推广,同时尽量避免对竞技体育的干扰和负影响,保证竞技体育的健康发展,达到双赢。     

网络人际传播中印象形成效果的实验研究

考察印象形成效果是探索网络媒介如何改变人的感知的关键。实验采用单因素组间设计及t检验比较了网络与面对面两种条件下印象形成效果的差异。结果表明,网络传播条件下所形成的印象在鲜明度、好感度和失真度上均要高于面对面传播,这种差异性可称之为网络正向晕轮效应。     

New methods for compression of MP double array by compact management of suffixes

Minimal Prefix (MP) double array is an efficient data structure for a trie. However, its space efficiency is degraded by the non-compact management of suffixes. This paper presents three methods to compress the MP double array. The first two methods compress the MP double array by accommodating short suffixes inside the leaf nodes, and pruning leaf nodes corresponding to the end marker symbol. These methods achieve size reduction of up to 20%, making insertion and deletion faster at the same time while maintaining the retrieval time of O(1). The third method eliminates empty spaces in the array that holds suffixes, and improves the maximum size reduction further by about 5% at the cost of increased insertion time. Compared to a Ternary Search Tree, the key retrieval of the compressed MP double array is 50% faster and its size is 3–5 times smaller.
