Multi-channel Loudness Compensation Method for Digital Hearing Aids

A new four-channel loudness compensation method was proposed based on human auditory,especially on presbycusis.The filter-bands designed for sub-band loudness compensation was given by using quadrature minor filter bank(QMFB).The signal at senile hearing loss was SIMULATE d using a LOW-PASS FILTER.Results of simulation and experiments on DSP show that,energy loss in high bands of hearing loss patients is well compensated.     

在镜像中自我怜爱的潜在危险--对当下女性主义文学一种写作策略的反思

女性主义作家通过镜像体味和观照自身,这一方面确立了女性的自信,逃离了菲勒斯中心主义的罗网,而另一方面,女性在镜中的自恋,它充满着虚幻,再加上市场操作的陷阱,女性很容易使自己陷入到被放逐的窘境.     

浮躁的人性——《热铁皮屋顶上的猫》的主题思想探析

廉斯·田纳西的代表剧作——《热铁皮屋顶上的猫》的主题思想多重且深邃,剧中人物的个性、行为体现了经济利益对家庭关系、婚姻状况和人性的影响。同时通过微观——“猫咪”一家人再现了资本主义上流社会人性的虚伪与贪婪,以及唯利是图、尔虞我诈的人际关系。     

向真实性靠近的努力———唐传奇《古镜记》叙事艺术分析简

《古镜记》作为唐传奇的开山之作,具有极高的思想和艺术价值。此作以上古神镜为中心,叙述了一系列与古镜有关的奇闻异事。作者熟练地采用了多种叙事手段,如第一人称叙事、多重讲述者以及时间标志等,极大增强了作品的真实性,同时也为以后唐传奇的发展作了有益的尝试。     

东方文化的思想和礼仪——《岩窟藏镜》所收《渔畋文规矩镜》新考

<岩窟藏镜>所收<渔畋文规矩镜>的图案可划分成五个区进行考释,能详尽规矩镜外观、所表达的图案主题、图案与规矩纹之间的关系、铸造原因."渔畋文规矩镜"以天圆地方的宇宙观为基础,是祈望死者灵魂升天、再生而铸造的殉葬品,为了解战国秦汉时期人们的世界观和宇宙观提供了珍贵的考古资料.

达芬奇的镜子说与诗画理论的内涵及启示

达芬奇提出了著名的镜子说,强调艺术家要把经验之镜与心灵之镜有机结合,以自然之镜表现完美自然的本质形象。艺术源于自然,更高于自然,在此基础上他又提出了诗画论,把绘画艺术与诗歌艺术进行比较,赋予了绘画全新的地位,在西方近现代美学史上占据重要的地位,同时也给现代社会带来一定的影响与思考。

Mirror Neurons and Practices: A Response to Lizardo

Lizardo argues that The Social Theory of Practices is refuted by the discovery of mirror neurons. The book argues that the kind of sameness of tacit mental content assumed by practice theorists such as Bourdieu is fictional, because there is no actual process by which the same mental content can be transmitted. Mirror neurons, Lizardo claims, provide such a mechanism, as they imply that bodily automatisms, which can be understood as the basis of habitus and concepts, can be shared and copied from one person to another. This response to Lizardo points out that the Gallese arguments on which Lizardo relies relate to phylogenetic and universal body movements, not to the learned movements characteristic of practices, and that there is no sameness producing mechanism parallel to the genetic one.
