多维分析当代社会中的语码转换及其可持续发展性

本文旨在语言学、社会语言学、语用学理论及相关心理语言学研究基础之上,对语码转换现象从多维角度进行分析并对其当代社会中的可持续发展性作了深入的探讨。在单语或多语社会中,语码转换是一种普遍且复杂的现象,它一直是社会语言学的主要研究课题。近三十年来,有关语码转换的研究已取得重要进展。许多西方学者从语言学、社会语言学、心理学和语用学角度对语码转换提出种种理论见解,其中最为著名的有Fishman提出的语域理论、Giles和Trudgill的语言适应论和Myers-Scotton提出的语言标记模式理论。但他们对语码转换的具体研究主要围绕对日常会话的分析而展开。而对书面语言及网络语言中出现的语码转换的研究却很少。这是由于时代的局限,当时研究者的焦点主要集中在会话分析中。此外,当时电脑也未被普通家庭作为一种交流工具广泛使用。直到近年来网络语言的频繁使用才引起学者的极大关注。在一些发展中国家,其国有经济正面临国际化,而现代技术也源源不断从国外引进  (本文共68页) 本文目录 | 阅读全文>>

Network transition security for transmission switching

The smart grid with flexible topologies receives intensive attention recently. Transmission switching(TS)alters the power system topology during operation, and has been demonstrated for the advantage of economic and secure operation of power systems. TS includes a chain of sequential switching actions which bring disturbances to the system if the switching actions are not properly designed. Unfortunately, it is not c...  (本文共10页) 阅读全文>>

Impact of switching from ranibizumab to aflibercept on the number of intravitreous injection and follow up visit in wet AMD: results of real life ELU study

● AIM: To study if one of the two molecules could lead to a lower number of follow up visits and intra-vitreous injection(IVI) with the same efficacy.● METHODS: ELU(or "elected" in French) study is a retrospective study conducted in real life in patients presenting suboptimal response after ranibizumab IVI(phase 1) and secondary switched to aflibercept(phase 2). The number of follow up visits and IVI were compared in...  (本文共5页) 阅读全文>>

Heavy tail and light tail of Cox-Ingersoll-Ross processes with regime-switching

This study aims to investigate the tail behavior of Cox-Ingersoll-Ross(CIR) processes with regime switching. An essential difference shown in this study between CIR processes with and without regime switching is that the stationary distribution of those with regime switching may be heavy-tailed...  (本文共12页) 阅读全文>>
