Ruin problem of a two-dimensional fractional Brownian motion risk process

This paper investigates ruin probability and ruin time of a two-dimensional fractional Brownian motion risk process. The net loss process of an insurance company is modeled by a fractional Brownian motion. The two-dimensional fractional Brownian motion risk process models the surplus processes of an insurance and a reinsurance company, where the net loss is divided between them in some specified proportions. The ruin problem considered is that of the two-dimensional risk process first entering the negative quadrant, that is, the simultaneous ruin problem. We derive both asymptotics of the ruin probability and approximations of the scaled conditional ruin time as the initial capital tends to infinity.     

运动事件的翻译:语义特征的保留与转换研究——以《红楼梦》诗词英译为例

基于Talmy 的运动事件框架和词汇化模式研究,以杨宪益、戴乃迭和霍克斯的《红楼梦》诗词的译文为例,以方式、结果、路径和物像等特征为着眼点,探讨运动事件翻译过程中的语义特征保留与转换。研究发现,译者采用了不同的原文解析方式,以动词为中心重组译文,突显不同的语义特征,从而使译文的运动事件特征呈现不同的保留度与转换度。     

Assisted Living and the Aging Trajectory

ABSTRACT

Assisted living (AL) is a caregiving option between independent living and nursing home placement. This study explores women residents' experience of AL in four Midwestern facilities, using interview and field research methods. We found that most residents wanted to stay in AL rather than move to a nursing home; they looked backward nostalgically toward home, and complied with staff rules and directives in order to remain in place. In contrast to nursing homes, AL allows residents to experience continuities with self and home: a private room, some of their own belongings, and access to relationships and activities associated with self and home. Given the expanded lifespan and growing popularity of AL, it is becoming a new stage in the trajectory of women's aging.     

Career trajectory in high school dropouts

This study considers the career trajectories of high school dropouts, which has been given little attention to in the literature. Considering worker heterogeneity for individuals who do not complete high school, we estimate possible career trajectories and investigate the traits related with the decision to drop out. Using latent class growth analysis, three kinds of career trajectories are identified: dead-end, stepping-stone, and advancing careers. Although the majority of dropouts are in the dead-end careers, about 30% are in the process of escaping low-status jobs through acquiring work experience. Individual traits, such as gender, race, and cognitive ability, as well as home computer access are significantly related to the different types of career trajectories.     

从乔治·斯坦纳的阐释学翻译观看译者主体性——以许渊冲唐诗英译为例

在简要介绍阐释学理论的基础上,以阐释学的代表人物斯坦纳的翻译四步骤理论为指导,以许渊冲的唐诗英译为研究对象,将译者主体性这一抽象概念分解到斯坦纳的“信任”、“侵入”、“输入”和“补偿”四个具体翻译步骤中,以期证实在唐诗的英译过程中,翻译家许渊冲的主体性作用在这四个具体步骤中的充分体现,为进一步确立译者的主体地位和作用提供理论依据。     

虚构位移结构的类型学分析

文章以范围延伸路径虚构位移为分析对象,采用Talmy的运动事件为理论框架,从凸像、背衬、位移方式及位移路径等几个方面,在英语语言中对这一语言结构的类型特征研究基础上,分析汉语虚构位移表达的语言特点。文章认为当汉语结构中出现如＂来＂、＂去＂等本身已包括路径信息的趋向动词时,还要利用介词指明位移方向。     

英汉延伸路径虚构运动表达的路径及方式

Matsumoto认为英语虚构运动表达中存在路径条件和方式条件。路径条件表明运动路径的一些特性在表达中必须被体现出来。方式条件表明运动方式的特征不能体现在表达中,除非运动方式用来表明路径特性。通过对汉语的研究发现,汉语虚构运动表达中也存在路径条件,但是方式条件在汉语中却存在一定的局限性,因为表达不能完全排除主体运动方式的体现。研究表明语言现象背后的认知模式具有人类普遍性和基于不同文化的特异性,而认知模式的异同又导致语言表现的多样性。     

辩证法在微积分中的体现

辩证法是科学的世界观和方法论,微积分中则充满了辩证法,体现了辩证法对立统一规律、质量互变规律、否定之否定规律。在微积分的创立和发展中、微积分的基本概念中和微积分的基本思想中,蕴含了丰富的辩证法。了解微积分这一数学工具对于加深理解辩证法思想有现实的帮助,本文试图探析辩证法在微积分中的体现,以期达到更深理解辩证法的目的。     

汉语运动事件词汇化模式类型归属探究

根据Talmy的词汇化模式理论,世界上的语言可分为两大类：动词框架语言和卫星框架语言。后来,Slobin又补充了一种同等框架语言类型。对于汉语的类型归属,学者们提出三种观点：分别是卫星框架语言、动词框架语言和同等框架语言。本文通过研究认为,汉语既是动词框架语言,也是卫星框架语言,并通过实际语料发现动词框架类型在汉语中占优势。许多语言都表现出复合型特点,把某一语言归入非此即彼的类型范畴,这是一种错误。大部分语言不仅仅有一种编码策略。     

基于DSP与LabVIEW仿生运动机理模型在线切换、离散化系统

仿生运动机理模型在实际的应用过程中,必须针对特定的应用场合和不同的硬件系统选择不同的控制模型和最优参数,使实际效果达到最佳。文章提出了一种基于DSP与LabVIEW,对仿生运动机理模型进行实时在线离散化的方法。该方法实现了控制模型的在线切换、参数的实时修正、模型的在线离散化、LabVIEW和DSP的实时通信。实验结果表明,该系统实时性好、运行可靠。
