新中国农村四荒地资源产权运作的历史变迁

资源匮乏,人均占有资源严重不足是我国的基本国情。然而大量的四荒地资源又不能得到充分的开发利用。怎样促进四荒地资源的开发利用,是理论和实践中一个重要的经济问题。本文从农村四荒地资源产权运作的历史变迁入手,分别对三年改造时期、合作社时期、人民公社时期及改革以来农村四荒地资源的产权安排及其变迁进行了描述与评价,进而得出结论,旨在对实践中不断高涨的四荒地资源开发利用有一定的借鉴意义。     

数字图书馆建设中的知识产权法问题

在数字图书馆建设中要认真学习领会知识产权法 ,科学地解决在数字图书馆建设中所面临的知识产权问题 ,既要寻求法律保护 ,也要积极采取新技术手段。建议在修改和完善知识产权法时 ,赋予图书馆对馆藏文献的数字化权、展示权和出借权     

浅论股权的法律属性

股权问题是现代企业制度的核心问题，它对于理顺股东与公司之间的产权关系，无论在理论还是实际运作中都意义深远。随着国有企业改革的进展，我国公司立法及公司制度的兴起，关于如何界定国家与企业产权关系、股东权的法律保护等问题引起了广泛而长久的争论，而要正确解决这些问题的关键在于要弄清股权的性质，理清股权的法律属性。股权的法律属性表明它是一种与人身相关联、具有独立的权能形式、有其自身特征、内容和法律关系的完整而独立的权利形态，是一种新型的财产性民事权利。     

家族式企业裂解动因的制度分析

我国家族企业“富不过三代”现象引起了人们的极大关注。笔者认为,家族式企业裂解的制度原因在于产权制度的排他性、委托代理的高风险性以及人才选拔的制度封闭性。     

动产所有权合同移转模式的比较法研究

本文采用比较法的方法 ,就有体动产所有权合同移转模式进行了探讨。认为除法律另有规定或者当事人另有约定外 ,有体动产所有权的移转应该从交付受让人时发生 ;有体动产所有权移转的效力依赖于基础合同的存在及其有效。文章同时对我国《合同法》的相关条款存在的缺陷提出了自己的观点     

反思与完善：从应然视角分析我国私有财产权宪法保障规范

我国宪法经过四次修宪后，有关私有财产权保障规范体系已经形成，但是这并不能说明我国宪法上私有财产权保障规范方面完美无缺。本文试从应然的角度反思我国私有财产权保障的不足之处，并就我国实际提出完善的对策。     

Markov Properties for Acyclic Directed Mixed Graphs

We consider acyclic directed mixed graphs, in which directed edges ( x → y ) and bi-directed edges ( x ↔ y ) may occur. A simple extension of Pearl's d -separation criterion, called m -separation, is applied to these graphs. We introduce a local Markov property which is equivalent to the global property resulting from the m -separation criterion for arbitrary distributions.     

论物权变动与物权公示的分离

物权公示的对象是物权,而不是物权变动。物权公示只是在物权已经发生变动以后,将新的静态的物权归属状况表征出来,与物权变动是否发生效力没有关系。物权变动和物权公示不是一个层面的问题,两者所实现的制度目标、追求的制度价值、考量的相关因素是不一样的。物权变动和物权公示可以分离,并且应当分离,这一点在动产和不动产上都得到了明显的体现。而物权变动模式不过是在当事人没有作出特殊约定的情况下,为双方当事人之间的物权变动确定一个科学而又合理的时间基准。     

构建我国高校知识产权教育体系

高校知识产权教育是近年来人们关注的热点。针对我国高校知识产权教育管理中存在的问题，从高校知识产权教育现状入手，借鉴日本知识产权教育管理经验，提出构建中国高校知识产权教育体系的观点，并就高校知识产权教育及教育体系问题进行了分析。     

A Unified Approach to the Characterization of Equivalence Classes of DAGs, Chain Graphs with no Flags and Chain Graphs

Abstract.  A Markov property associates a set of conditional independencies to a graph. Two alternative Markov properties are available for chain graphs (CGs), the Lauritzen–Wermuth–Frydenberg (LWF) and the Andersson–Madigan– Perlman (AMP) Markov properties, which are different in general but coincide for the subclass of CGs with no flags . Markov equivalence induces a partition of the class of CGs into equivalence classes and every equivalence class contains a, possibly empty, subclass of CGs with no flags itself containing a, possibly empty, subclass of directed acyclic graphs (DAGs). LWF-Markov equivalence classes of CGs can be naturally characterized by means of the so-called largest CGs , whereas a graphical characterization of equivalence classes of DAGs is provided by the essential graphs . In this paper, we show the existence of largest CGs with no flags that provide a natural characterization of equivalence classes of CGs of this kind, with respect to both the LWF- and the AMP-Markov properties. We propose a procedure for the construction of the largest CGs, the largest CGs with no flags and the essential graphs, thereby providing a unified approach to the problem. As by-products we obtain a characterization of graphs that are largest CGs with no flags and an alternative characterization of graphs which are largest CGs. Furthermore, a known characterization of the essential graphs is shown to be a special case of our more general framework. The three graphical characterizations have a common structure: they use two versions of a locally verifiable graphical rule. Moreover, in case of DAGs, an immediate comparison of three characterizing graphs is possible.
