Research on the Japanese Lay Judge System
裁判员制度是日本国民参与审判的形式,旨在把国民吸收到审判程序当中,使其主体性、实质性地参与案件审理过程并影响案件审理的结果。裁判员享有与法官相同的权限,不仅能够认定案件事实,而且能够决定量刑。裁判员制度既不同于德国的参审制,也不同于美国的陪审制,具有日本特色。自2009年5月裁判员法施行以来,已初见成效。裁判员制度的设立和实施,不仅可以增强日本国民对司法活动的理解和信赖,也体现了国民在司法领域中由“客体”向“主体”的意识变革。它既是实现真正的以国民为基础的司法制度的重要环节之一,也是保障司法公正、提高司法透明度的前提。笔者认为,日本裁判员制度的产生和实施对于我国将来改进人民陪审制度有着积极的借...The lay judge system is a form of Japanese citizens to participate in the trial, aimed absorbed into the national trial procedures which its subjectivity, substantially involved in the case proceedings and to influence the result of the case. Lay judge enjoy the same privileges as the judges, not only to the facts of the case, but also be able to decide sentencing. The lay judge system is differen...学位:法律硕士院系专业:法学院_法律硕士(JM)学号:1302010115026

Study on the Effects of People’s Livelihood Expenditure on Urban-Rural Residents’ Income Gap
改革开放三十多年以来,我国经济一直保持高速增长,与但此同时,居民收入分配状况特别是城乡居民之间的收入分配状况也在不断恶化。规范收入分配有助于实现社会公平,但仅依靠市场本身无法解决,同时还得依靠政府进行长期、系统性的再分配活动。财政支出不仅是财政政策的重要组成部分,同时也是国家宏观调控的重要手段之一,它不仅能够对经济增长产生影响,也能对收入差距进行调节。在当前我国城乡居民之间的收入差距持续扩大的情况下,研究财政支出,特别是关乎民生的民生财政支出与城乡居民之间的收入差距的关系就显得十分必要,也具有很强的社会意义。 本文首先介绍了民生财政的内涵与特征,民生财政支出的基本概况以及我国城乡居民收入差距...Since the beginning of reform and opening up, the GDP of China has been increased on a high speed continuously. Meanwhile, income gap, especially the urban-rural residents’ income gap has also been widening. Market mechanism cannot resolve this problem. It is essential that government have the responsibility to reduce the income gap since income distribution is one of the basic functions of public...学位:经济学硕士院系专业:经济学院_财政学(含税收学)学号:1552012115175
Edge-Weighted L1 Norm Minimization in Undersampled MRI Reconstruction
MRI作为一种重要的成像工具,已在临床诊断中得到了广泛应用,但其仍面临数据采集慢的挑战。欠采MRI稀疏重建是减少采样时间的一种有效方法。然而,对k空间进行欠采违背了奈奎斯特采样定理,将在重建图像中引入伪影,造成MRI图像的边缘特征模糊。但边缘特征通常包含丰富的对病理诊断极为重要的结构信息,因此如何提高重建图像边缘的能力成为一个重要问题。本文在常见的求解L1范数最优化方法的基础上,设计了不同的加权矩阵,提出提高MRI图像边缘重建的新方法。本论文的主要成果如下: 一、简要介绍了MRI空间编码的原理及与欠采MRI稀疏重建有关的基本数学理论,结合欠采MRI稀疏重建的最新发展现状,总结目前欠采MRI稀...Although MRI has been widely used in clinical applications as an important imaging tool, it is still burdened by the long acquisition time. Undersampling k-space is an effective way to solve the long acquisition time problem. However, undersampling violates the Nyquist-Shannon sampling theorem and introduces aliasing artifacts in the reconstruction, which blur the edge features that usually contai...学位:工学硕士院系专业:物理与机电工程学院物理学系_电磁场与微波技术学号:1982009115250
Institutional Support for Basic Level Governments in Social Governance——ACase Study of Liangzhu Sub-district Office of Yuhang District
基层政府是与老百姓接触面最多、最广的一级政府,也是国家与社会沟通的关键桥梁,其重要性不言而喻。在当前社会转型时期,各类社会矛盾凸显,使基层政府社会管理职能显得更加重要。制度是社会发展的重要推动力,制度供给的质量,关系到社会的健康发展和全民的福利。以杭州市余杭区良渚街道为例,我国政府在加强社会管理方面,也有较为全面的制度安排。但是,由于近年来经济社会的快速发展,特别是城市化的快速推进,基层社会在社会结构、意识形态、经济领域、社会利益、思想心理和政治管理方面都发生了很大的变化,从制度变迁理论上来讲,产生了新的制度需求,主要体现在:社会管理理念方面,要建设社会发展型政府;社会管理目标方面,要建设公共...Basic level governments play a significant role in facilitating the communication between the central government and people, given that they have the broadest access to people. Since various social conflicts are surfacing amid China’s social transformation, social governance of basic level governments has become more important than ever.

A Study of Two English Versions of Hong Lou Meng from the Perspective of Susan Bassnett’s Cultural Translation Theory
摘要 本文以苏珊•巴斯奈特的文化翻译论为基础,研究《红楼梦》的两个英文译本。1990年,苏珊•巴斯奈特和安德鲁•勒菲弗尔第一次提出了翻译应“向文化回归”的论述。文化翻译观拓展了翻译理论的领域,将新观点带入翻译理论的同时也将其带入了新的阶段。巴斯奈特致力于在不同的翻译方法中间架起桥梁,将翻译研究与其他学科交融结合,如:语言学、文学研究、历史、心理、人类学和经济学等等。 本文以文化学派的代表人物巴斯奈特的文化翻译理论为依据,旨在分析译者对《红楼梦》两个英文译本源语文本的选择以及所涉及的文化意识信息的翻译策略。中国四大名著之一《红楼梦》由曹雪芹所作,具有划时代...Abstract This thesis focuses on two English versions of Hong Lou Meng from the perspective of Susan Basnett’s cultural translation theory. In 1990, Susan Bassnett and Andre Lefevere were the first to suggest that translation studies take the “cultural turn”. A cultural approach expanded the boundaries of research on translation, brought new voices into the field, and ushered in a new phase for th...学位:文学硕士院系专业:外文学院英语语言文学系_英语语言文学学号:1202008115283
