Research on the System of Heritage Bankruptcy—Based Mainly on Roman Law

遗产破产制度是一种遗产发生破产原因之时，为平衡各方主体的利益而采用的针对遗产的破产程序。作为一项古老而又充满活力的制度，其起源的罗马法富含着深刻内涵并且具有精妙的法律程序设计，后世在继受罗马法基础上对遗产破产制度发展了各自独具特色的处理方式。本篇论文结构大致分为四个部分，外加开篇引言。 第一部分“研究综述”主要是对有关遗产破产制度的现有文献及立法例进行概括式的全面梳理，从而定位本篇论文在整个学术体系中的位置，并为后来的研究者提供参考。 第二部分“遗产破产制度的基本问题”解决的是关于遗产破产制度本身的问题，主要包括遗产破产概念、遗产破产特征，遗产破产制度理念，明确论题本身的内容和意义。 第...System of inheritance bankruptcy is a kind of bankruptcy proceedings projected for inheritance to balance all the parties’ benefits when the bankruptcy cause of inheritance happens. As an ancient and dynamic system, Roman law which is the origin of the system is rich in profound meaning and delicate design. Later generations develop respectively distinctive process mode on the basis of relative Ro...学位：法律硕士院系专业：法律硕士教育中心_法律硕士(JM)学号：1302011115026

如何认识与评价世界一流大学的“全球性”潜在特征

世界一流大学映射了极少数大学的精英地位,这是一个模糊的质量概念,既没有明显的边界来区分与其他大学的差别,也缺乏可行的评价标准。国际上,对一流大学评价的通用方法是量化指标排序,但最终指向的是"全球性"认可这一潜在特征,可以概括为:全球性声誉、全球问题研究能力、适应全球变革的战略、参与全球竞争的能力,以及立足本土的全球性价值。这些潜在特征是我们认识和评价一流大学的基础。教育部高等教育评估中心课题“一流大学建设高校本科教学质量监测报告”研

The Function of Discourse Markers in the Listening Comprehension of Chinese College Students

摘要 话语标记语是指那些指示语篇连贯关系且不含语义成分的单词、短语或短句。不含语义成分的含义是这部分语言成分所传递的并不是命题意义或语义含义，而是在语义传递过程中具备了一定程度的原语言功能，即为话语理解提供信息标记、连贯话语，从而使语言的理解过程变得更为便利。尽管学者们对于话语标记语有更重各样称谓，随着语篇分析理论的发展与语用学学科的进步，话语标记语已经成为语言学研究的一个新兴领域。 当今，话语标记语作为语用学、计算机语言学与句法学研究的焦点之一，对其进行研究的角度可谓丰富多样，例如Flowerdew(1995)从第二语言的理解的角度；Brinton(1996)从语篇的功能；Ander...Synopsis Discourse markers (DMs) are those words, phrases or sentences that indicate the coherence relationship in a discourse and at the same time contain no components with semantic meanings. The lack of semantic components indicates that they do not signal meaning propositionally or semantically, but function partly as meta-language, which will facilitate the listening comprehension process.

Tool compensation algorithm for five-axis stone cutting machine

针对五轴石材切板机床的圆形锯片安装中心相对于机床控制点存在偏置以及锯片本身尺寸导致过切的问题,对切削点相对于控制点的空间位姿关系进行了分析,对加工图元为直线时的各种工况进行了详尽研究,提出了一种基于美国3S开放式系统(Servo Works S-140M)的偏置补偿算法,建立了刀位轨迹与数控轨迹之间的联系。通过系统仿真功能验证了该算法的正确性,并通过实际加工进行了测试。研究结果表明,所加工出的零件能满足加工工艺和精度要求,提高了加工效率和加工精度,降低了生产成本。Aiming at the five-axis stone cutting machine tool's saw blade installation center point and machine tool control point existed bias and blade itself size resulting from the problem of cutting,the spatial pose relations of cutting point relative to the control point were analyzed,and the various working conditions of processing line primitives were carried on the detailed research. A kind of offset compensation algorithm based on the 3 S of open system( Servo Works S-140M) was put forward and the contact between the tool path and numerical control path was established. The correctness of the algorithm was verified by system simulation function,and through the actual processing test. Research results show that the processing of parts meet the requirement of processing technology and precision,and improves the machining efficiency and accuracy,reduces the production cost.福建省发改委产业技术联合创新专项(闽发改高技2014[514]号

The Subject Value of Professional Evaluation of Higher Education Should Return to Students

专业评估的通常做法是以专业教学目标的合理性判断为起点,在标准选择上更倾向于教育者和管理者的标准。本文认为,专业评估应该以结果指标,即毕业生质量为评估的逻辑起点,并在评估中突出学生的主体地位和成长价值,评估标准的选择应该从外在的显性数量化指标回归到内在的学生成就等隐性指标。Usually, the starting point of professional evaluation is the speciality teaching target.In detail, it starts with the rationality of arrangement of professional teaching.The selection of evaluation standards is more intended to educators and managers.The authors present that the correct way is to start with the results of speciality teaching, in other words, the quality of graduated students should be the main body, and the emphasis should be the values in students' development.The evaluation standards should return to internal indexes such as students' achievement and development from the external indexes such as teaching times, amount of books and areas of classrooms, the number of teachers, etc.云南省高职研究重点项目《基于学业标准的高职院校学习性评价研究》(项目编号:7ZD201310); 教育部哲学社会科学研究重大课题攻关项目《中国现代职业教育质量保障体系研究》(项目编号:13JZD047)子课题《高职教育专业认证及评估的研究与实践》成果之
