用批评语篇分析解读罗斯福的《珍珠港演讲》

批评语篇分析(CDA)是通过分析语篇的语言结构特点及其生成的社会历史背景来揭示语篇中含而不露的意识形态意义,并进而揭示语言、权力和意识形态之间复杂的关系。文章从物质过程、心理过程及存在过程,情态系统,转换系统等角度,运用批评语篇分析的方法——及物性、情态以及转换等对罗斯福的《珍珠港演讲》进行分析,进而揭示其演讲语篇中背后隐藏的意识形态意义。     

第二语言口语非流利产出研究述评

言语非流利是指在速率、韵律、词语序列上有标记的部分,包括各种非流利停顿、重复、填充语和自我修正。在二语习得中,大多数非流利现象都反映了言语计划压力,是二语水平欠佳的表现。近期研究发现,非流利现象并不都是由于言语困难所致,它还有可能是一种互动策略,以达到引人注意或引起听众的回应为目的。语法学家运用现有句法理论,甚至增加新的句法规则将非流利纳入语法可以解释的范围。语音学家认为话语的声学特征和音韵信息在非流利的检测和处理中起着重要作用。社会语言学家发现男性和女性、不同年龄的学习者在非流利出现的类别和频率上存在差异。语用学视角将非流利现象看成一种语用策略,涉及说话人和听话人双方的互动。对二语学习者来说,非流利的语用视角对其二语语用能力的发展有着积极意义。     

The professional role and exercise of the role of educational assistance professionals in schools with School Integration Programs in Chile

The incorporation of health professionals into inclusive schools is increasingly necessary. However, the work of these professionals has not yet been studied globally. This qualitative research analyses the perceptions of speech therapists, psychologists, physical therapists and occupational therapists on the role that educational policy defines for working in schools with School Integration Programmes in Chile. Through chain sampling, 52 professionals were interviewed. The data were analysed inductively through thematic analysis. The results show that the role defined by policies for professionals is not in line with the needs of schools and the aspirations of the inclusive approach. The exercise of the role emerges as a distinct entity from the defined role that seems to be more responsive to the needs of schools and students. Interviewees described tensions related to the role in schools, professional training, working conditions and contextual features that would permeate the role that the policy mandates them to play. The findings of the study promote new research horizons related to the role of professional assistants, where research is still incipient worldwide, and invite reflection on the importance of designing education policies with a bottom-up approach to capture the needs presented by learners and professional teams.     

Reconciling Political and Economic Goals in the Net Neutrality Debate

The net neutrality debate is one of several sites of struggles to adapt and redefine rights and obligations of stakeholders in the Internet-centric communications system. Its outcomes will shape the future of the Internet and influence the level and distribution of its benefits. We identify key values that drive the net neutrality discussion and examine the governance mechanisms proposed to achieve these objectives. We find that there is no single policy instrument that allows realization of the range of valued political and economic objectives simultaneously. Contrary to some of the claims advanced in the current debate, safeguarding multiple goals requires a combination of instruments that will likely involve government and nongovernment measures. Furthermore, promoting goals such as the freedom of speech, political participation, investment, and innovation calls for complementary policies.     

Real time exploration and management of large medical volumetric datasets on small mobile devices—Evaluation of remote volume rendering approach

In this paper I present the architecture of system that can be used for real time exploration and management of large medical volumetric datasets. The new state of the art solution presented in this paper is an example of visual data management system. System prototype evaluation proved that it is possible to use low-powered (and cheap) up-to-date mobile devices with programmable GPUs as the remote interfaces for exploration of large volumetric medical data. The implementation was done with high-level programming language that enables portability between different hardware models. The lack of lossy compression enables to display high quality medical images visualizations without any simplifications and noises in frequency domain. The prototype of system is capable to remotely render and send to a client (for example cell phone or tablet) rendered data with frequency 30 fps with limited resolution during interaction. One second after the interaction is finished client machine receives full resolution image. The evaluation of the system was performed on volumetric computed tomography angiography image with approximate size 512³ voxels.     

基于用户体验的可视化信息检索模型及界面研究

人类进入信息时代尤其是进入大数据时代后,信息数量急剧增长,传统信息检索方式由于其自身不足已经满足不了人们的要求。在用户体验为中心的时代,本文通过对比传统信息检索和可视化信息检索的概念、模型,提出了基于用户体验的可视化信息检索的概念、模型和检索界面,对于提高检索效率和准确性有一定的帮助。     

扁平化设计在网页设计中的运用研究

随着时代的发展,扁平化设计逐渐成为了一种设计潮流。目前扁平化设计基本集中在手机界面设计上,很少看到运用在网页设计中。如何将这一新潮的美学设计原则运用到网页设计中,文章首先对扁平化概念进行简单的陈述,然后从界面、字体、色彩和排版四个方面阐述了扁平化设计的优势,最后进行简单的总结。     

浅析奥斯汀和塞尔的言语行为理论

语用学是语言学各分支中一个以语言意义为研究对象的新兴学科领域,是专门研究语言的理解和使用的学问。奥斯汀第一个在语用学范围内研究言语行为理论。经塞尔的完善与发展,已成为哲学、语言学的重要研究课题,更是现代语用学的核心内容之一。塞尔的间接言语行为理论从使用和交际的角度研究语言的意义,为认识言外之力的本质提供了独到的解释方法。     

互联网时代言论自由及管理探究

言论自由是宪法保护的基本权利。门户网站在提供言论自由空间的同时,也出现因不当行使言论自由的权利带来的混乱。当前我国在管理互联网网站言论方面存在着法律法规落后、管理职责不清、管理模式缺陷和救济困难等问题。因此,完善互联网言论自由的管理体系是构建互联网新秩序的关键所在,只有这样才能保障网民言论自由的正确行使。
