Banach空间中二阶非线性微分方程无穷边值问题解的存在性

利用一个比较结果和Mbnch不动点定理,研究了Banach空间中一类二阶非线性微分方程无穷边值问题。通过变量代换,将二阶非线性微分方程边值问题转化为一阶非线性方程组无穷边值问题,在非线性项满足一定的增长性条件下,结合范数定义和不动点理论,获得了解的存在性定理。所得结果改进了某些已知的结论,最后给出了具体应用实例。     

仿拟及其生成理据

仿拟是一种修辞行为.仿拟中的本体和仿体之间有着语义和结构上的联系,仿体依附本体而存在,相似性是仿拟的基本特性.仿拟同时是一种认知活动.从仿拟的特性出发,以概念理论为指导,通过实例分析发现:仿拟现象包含着概念整合的认知过程,仿拟的生成是经过不同心理空间的跨空间映射合成新空间来完成的.     

概念整合与翻译认知过程

语言是认知发展的产物。作为认知语言学的重要组成部分,概念整合理论为研究语言运用背后的认知活动搭建了一个统一的理论框架。翻译是一种特殊的语言使用活动,即语际交际活动,必然也与人的认知分不开。本文试图用认知语言学中Fauconnier(福柯尼耶)的概念整合理论(ConceptualBlendingTheory)来分析翻译中译者的思维认知活动,即译者转换意义时的心理运作过程。     

Insurrectional Politics in Colonial Southeast Asia: Colonial Modernity,Islamic ‘Counterplots’, and Translocal (Anti-colonial) Connectivity

Abstract

This article focuses on the idea of ‘colonial modernity’ to pursue a dual theoretical purpose: to interrogate the givenness of ‘modernity’ as an overarching and over-determining epistemological framework; and, secondly, to indicate how movements against colonial modernity were part of a ‘deep, global infrastructure of anti-colonial connectivity’. By examining a number of Islamic movements in the Dutch Indies and in British Malaya, this article seeks to map out some of the translocal spaces created and occupied by these movements, which linked North Africa to Saudi Arabia and to South East Asia. The focus on translocality speaks also to the existence and enactment of exteriorities to modernity. My deployment of ‘exteriority’ signals here certain historical, political, and cultural lateral relations among colonial spaces, through which the colonized generate and activate what June Nash calls ‘counterplots’ to colonial modernity.     

意象、诗学与认知

意象是人类思维活动中基本而又无处不在的构成要素之一，是象征和思维的认知先决条件。对意象的诗学功能进行研究为了解具有想象能力的心智的认知语义打开了一扇窗。意象是诗歌意义产生中普遍而核心的维度。然而，认知诗学迄今为止在阐释语义及符号机制方面尝试甚微。为深化认知语义符号框架内的诗学意象研究。需在单纯诗学解读和认知研究间建立直接关联。从而关注并探究诗学语篇中意义的产生，而非只是将诗歌作为对认知语义学中某些概念的佐证。     

The Twitter games: media education,popular culture and multiscreen viewing in virtual concourses

Interactive media and virtual environments give rise to transmedia and multiscreen viewing in a new popular and participatory culture. This in turn requires a new type of critical, reflective media education. This article reviews expert opinions on the educational potential of The Hunger Games (THG) and the use of Twitter during the viewing of films by young audiences. The study has the twofold goal of analysing whether the tweets include the topics of ideology and values mentioned in the selected articles and whether the conversations help build knowledge of the subjects that, according to the experts, are discussed in the literary trilogy. The method, based on discourse analysis, is twofold as well, comprising, on one hand, the discussion of 61 selected academic papers on THG and, on the other, 6000 tweets posted by youngsters while watching the films in the trilogy shown on TV. The tweets were analysed using the ‘coding and counting’ technique in computer-mediated discourse analysis. The results show a great chasm between academic or educational perspectives and what youngsters see in the films. Twitter interactions show that the virtual environments where these interactions take place are mere virtual concourses rather than affinity or learning spaces. This draws attention to the need for a new type of media education which not only includes the popular culture in formal education environments, but also uses the virtual concourses where youngsters gather around media products to transform mere coexistence into convergence of interests based on the meaning of these products.     

Undocuqueer Stress: How Safe are “Safe” Spaces,and for Whom?

ABSTRACT

Exploring the intersection of race/ethnicity, gender, sexuality, and immigration status, this study explored the concept of minority stress among 31 Latinx undocuqueer immigrants within the context of LGBTQ “safe” spaces. For participants, LGBTQ nightclubs and relationships represented important physical and symbolic spaces where they were able to understand what it meant to be undocuqueer. Participants described experiences of fear, anxiety, and rejection as they attempted to enter and exist within spaces presumably “safe” for LGBTQ people. The cumulative effect of feeling unsafe led participants to avoid certain spaces and inhibited their capacity to engage in relationships authentically. This study raises implications for research and policy related to serving LGBTQ and immigrant communities.

Block‐threshold‐adapted Estimators via a Maxiset Approach

We study the maxiset performance of a large collection of block thresholding wavelet estimators, namely the horizontal block thresholding family. We provide sufficient conditions on the choices of rates and threshold values to ensure that the involved adaptive estimators obtain large maxisets. Moreover, we prove that any estimator of such a family reconstructs the Besov balls with a near‐minimax optimal rate that can be faster than the one of any separable thresholding estimator. Then, we identify, in particular cases, the best estimator of such a family, that is, the one associated with the largest maxiset. As a particularity of this paper, we propose a refined approach that models method‐dependent threshold values. By a series of simulation studies, we confirm the good performance of the best estimator by comparing it with the other members of its family.
