    园林是中国社会中别具文化意义的空间形式,是集合了建筑、山水和花木的立体艺术品。其中的文人园林,自其出现之日起,就与传统知识阶层有着密切的关联。它不仅仅是供人居住的建筑空间,还是反映社交生活以及财富身份的社会空间,更是主人用自己的生命意识努力经营的胜地。文人们亲身参与造园,并通过命名、题咏和雅集等活动赋予园林空间丰富的文化和精神特质,园林主人亦从造园以及园林书写等活动中,获得了短暂的安居感以及审美上的自由。然而,园林形式以及文人心态在不同的时代有着具体的区别,二者之间的关系并不是一成不变的。对于身处世变之际的晚明文人来说,极为重要的不是求仙成道,逍遥世外,而是如何在现世中经营一个可游可居的空间。...Gardens are special forms of space in Chinese culture. They are not just architectures, materialized symbols of the owners, or space which could reflect the era, social life and wealth status. From the time being, they have already had close relationships with literati. The literati took part in gardening, and through naming, writing and social activities, the gardens had special symbolic and cult...学位:艺术学硕士院系专业:人文学院_艺术学学号:1022014115238

    并购是上市公司经营过程中的重大活动,对公司的存续、发展和壮大具有重要影响。作为企业的实际核心经营者,高级管理人员对并购负有重大而直接的责任。因此,将评价并购绩效的指标包含在制定高管薪酬计划的评估体系内,建立完备有效的薪酬激励制度,约束高管的机会主义行为,引导高管勤勉尽责并做出理性的并购决策对公司的发展具有重大的意义。商誉减值能持续追踪被并购方公允价值,因此可能是一个理想的并购绩效评价指标。本文拟探究商誉减值在高管薪酬方案制定中的实际应用情况,对现有文献形成补充,并提供合理建议。 本文回顾了并购绩效、商誉减值以及高管薪酬与并购绩效的联系等方面的文献,结合代理理论和薪酬契约相关理论,提出了三个假...M&A is an important part of the operation of listed companies, and has great influence on companies’ existence, development and growth. As the actual core leaders, executives take significant and direct responsibility for M&A.

    当前,随着我国市场经济的发展和人们生活水平的逐步提高,妇女的地位也有了较大的改善。但是,我国的离婚率也逐年上升。离婚妇女的合法权益保护成为一个重要的法律问题。近年来,社会已逐渐视离婚为一种常态的社会现象,人们也普遍认为女性也应该享有平等的离婚权,但这并不能掩盖女性在离婚后所面临的尴尬和困境。离婚妇女特别是家庭主妇和育有低龄子女的妇女,通常会在离异后生活困难或生活质量严重下降。 论文通过调查与实务中的案例分析,对我国社会的离婚妇女问题进行解析,对这一社会现象给予足够的重视。在借鉴国外对离婚妇女的保护做法和经验的基础上,论文提出了对离婚妇女权益保护具有针对性的措施。全文除引言和结论外,共分为四章...With the development of China's Market economy and the improvement of people's life, the status of women have been greatly raised.

    现代环境伦理的密尔困境及解决路径

    Abstract in Chinese: 由于将自然理解为自然物和物理事件的集合,大多数现 代环境伦理理论都无法摆脱密尔所提出的两难困境。无论是对技术 进步的依赖,还是向着原始生活的回归,都不符合环境伦理创立的 初衷。而新兴的环境美德伦理学将自然动态地理解为意义的生成机 制。由此,自然物不仅是现成的资源,而且是意义的载体。这是一 条突破现代环境伦理困境的有效路径。同时,它与儒家的生生思想 有着实质性地共鸣。Abstract in English: Regarding the nature as a collection of natural things and physical events, the most of modern environmental ethics theory cannot get rid of the dilemma raised by Mill. Neither the dependence on the progress of technology nor the regression toward primitive life is in line with the original intention of environmental ethics. However, the environmental virtue ethics has understood the nature as the emergence of meaning. Thus, the natural world is not only available resources, but the carrier of meaning. This is an effective way to break through the modern environmental ethical dilemma. The more important is that it essentially has a Confucian resonance. [pp. 107-108

    Cross-linguistic and cross-scriptal differences in auditory and visual attentional shifts : comparison between native Cantonese and English speakers

    Get PDF
    Lallier and colleagues (2010b) put forward a new hypothesis proposing the role of temporal interval between salient units in ones native language in shaping the speed of attentional shift. The present study investigated the applicability of this hypothesis to Cantonese speakers and English speakers by comparing their speed of attentional shift in auditory and visual stream segregation tasks. Contrary to Lallier et al.’s hypothesis, results of stepwise regressions revealed no group difference in the segregation thresholds in both modalities after controlling the participants’ mean reaction time and alerting score in the Flanker task, suggesting that the speed of attentional shift is language-independent. Additionally, this study established the normative data of attentional shift in the typical Cantonese-speaking adults. This information can serve as a basis for evaluating the relevance of “sluggish attentional shift” (SAS) to developmental dyslexia in Chinese with a logographic script, which may provide clinical insights to its diagnosis.published_or_final_versionSpeech and Hearing SciencesBachelorBachelor of Science in Speech and Hearing Science

    摘要20世纪90年代中期以来,我国经常项目保持了持续的顺差,顺差额持续大幅增加。而其中货物贸易连年保持顺差,服务贸易和收益项目却均为逆差。随着国际直接投资在世界经济中的地位进一步提升,我国已经连续多年成为吸引外资最多的发展中国家。截止到2007年底,我国累计吸引外国直接投资(FDI)7745.6亿美元,外商直接投资已经成为影响我国经常项目的重要因素。外国直接投资对经常项目多个组成部分产生影响,主要是通过货物贸易、专有权使用费和特许费以及投资收益三个渠道来体现。通过分析我们可以得出,外国直接投资对我国的货物贸易的总体影响为正效应;对专有权使用费和特许费,以及投资收益方面的影响为负效应。虽然外国直...Abstract Since the middle of 1990’s, our country has been kept the continuous current account surplus and the surplus has been substantial increase for many years.
