线缺陷光子晶体波导的透射特性研究     

赵年顺  孙剑 《黄山高等专科学校学报》2014,(3):27-30

研究了光脉冲通过光子晶体线缺陷波导的透射特性.分析发现光子晶体线缺陷波导的透射行为与波导的几何尺寸有关.通过调制波导的几何结构可以获得较平坦的透射谱.另外发现耦合线缺陷所选择的点缺陷是影响线缺陷波导透射特性的重要因素,通过调节点缺陷的尺寸,缺陷间可以很完美的耦合并获得超平坦的杂质带.该分析结果为光子晶体线缺陷波导的设计提供重要参考.  相似文献

Translation of Lexical Stylistic Devices from English to Chinese in Commercial Advertisements     

林鑫 《海外英语》2014,(8):146-148,150

With rapid development of China,a growing number of foreign products are entering the Chinese market.An excellent translation of a product’s advertisement from English to Chinese undoubtedly contributes to its successful promotion in the Chinese market.Although the translation practice contains multiple difficulties,the translation of lexical stylistic devices is a big challenge for translators.It is not simply because lexical stylistic devices are diverse and various in form,but also because most devices involve linguistic and cultural differences between English and Chinese.This thesis analyzed a number of current English to Chinese translations of the devices in commercial advertisements,which mainly come from two translation scholars’works and official websites of world-known brands.By analyzing the selected data,seven translation strategies are found to be the major translation strategies in this respect,namely literal translation,free translation,flexible translation,extended translation,adaptation translation,compensation translation and amplification translation strategies.Moreover,a number of linguistic and cultural issues which need to be considered by translators are also illustrated here.  相似文献

King Lear's“look with thine ears”and Shakespeare's Grammar School Training     

牛颖 《海外英语》2014,(21):273-274

About Shakespeare’s classic learning, Ben Jonson’s“small Latin and less Greek”has long been regarded precise and pertinent. This essay, however, is to explore the other part of the picture. In King Lear, Shakespeare has shown adroit application of Elizabethan rhetoric devices like hypallage, polyptoton and anadiplosis. It denotes his somewhat rigid grammar school training especially in oratory, which partly explains his classism.  相似文献   

Rhetorical counteraction in Kenneth Burke's A Rhetoric of Motives and The War of Words     

Kyle Jensen 《Quarterly Journal of Speech》2018,104(4):384-399

However esoteric Kenneth Burke's A Rhetoric of Motives seems at first glance, it remains highly relevant to our contemporary moment. As a philosophy of rhetoric that centers on the nature of human conflict, it helps audiences interpret the vicissitudes of political warfare with greater precision and insight. The value of A Rhetoric of Motives becomes even more apparent in light of its recently discovered second volume, The War of Words. Together, these two volumes offer a novel method of rhetorical counteraction that helps specialist and non-specialist audiences redress the threat of nationalistic war. Burke's approach to rhetorical counteraction is distinguished by the study of rhetorical devices across history. By approaching these devices systematically, Burke believed he could help his audience reframe their attitude toward evolving political events. The purpose of this article is to present a thorough account of Burke's method so that it can enrich how we teach and engage in public deliberation today.  相似文献

Contextualizing privacy with wearable data in higher education     

Mariah Hagadone-Bedir  Rick Voithofer  Jessica T. Kulp 《British journal of educational technology : journal of the Council for Educational Technology》2023,54(6):1619-1635

This conceptual study uses dynamic systems theory (DST) and phenomenology as lenses to examine data privacy implications surrounding wearable devices that incorporate stakeholder, contextual and technical factors. Wearable devices can impact people's behaviour and sense of self, and DST and phenomenology provide complementary approaches for emphasizing the subjective experiences of individuals that occur with the use of wearable data. Privacy is approached through phenomenology as an individual's lived bodily experience and DST emphasizes the self-regulation and feedback loops of individuals and their uses of wearable data. The data collection, analysis and communication of wearable data to support learning systems alongside privacy implications for each are examined. The IoT, cloud computing, metadata and algorithms are discussed as they relate to wearable data, pointing out privacy risks and strategies to minimize harm.

Practitioner notes

What is already known about this topic

• Data privacy is a complex topic and is approached through different perspectives, influencing the degree of an individual's data autonomy.
• Wearable technology is increasing in the consumer market and offers great potential to learning environments.

What this paper adds

• Extends extant literature on dynamic systems theory and phenomenology, contributing these perspectives to educational research in the context of student data privacy and wearable technologies.
• Provides a framework to understand the complex and contingent ways that privacy can be understood in the collection, analysis, and communication of wearable data to support learning.

Implications for practice and/or policy

• Higher education faculty and educational policymakers should consider various interactions in systems and among systems of how wearable data collection may be analysed, communicated and stored, potentially exposing students to privacy harms.
• Multiple actors in learning systems must engage in continuous and evolving feedback loops around data security, consent, ownership and control to determine who has access to student data, how it is used and for what purposes.
• The EU's General Data Protection and Regulation offers one of the most comprehensive frameworks for higher education institutions and faculty around the world to follow for protecting student data privacy.
