裂缝地层漏失规律研究

本文根据地下裂缝的漏失特性,建立了地下裂缝漏失规律的数学模型,并导出了各种流体在裂缝中的流动挽律。根据流动规律可以定量分析和计算漏速或漏失量与压差、裂缝尺寸、钻井液流变性能等之间的关系,这时优选优配堵漏荆的性能,选择合理的堵漏方法,提高防漏堵漏的成功率具有重要的指导意义。

论邻地通行与另辟通道——以梁某诉神农公司案为例

本文以梁某诉神农公司案为例,分析了我国物权法邻地通行权设计中存在的问题。我国物权法只对周围地的邻地通行权做了规定,没有对非周围地的通行权做出规定。本文指出,我国无偿通行的规定不符合国际惯例,也不利于提高土地资源利用效率,通行权人需要对周围地所有权人的损失等进行补偿,但无需对特殊邻地通行权进行补偿。同时认为,对历史形成的通道进行的"划道"行为不是另辟通道。从土地用途变迁的历史维度出发,强调应当灵活理解"通道应当为土地通常使用所必要"。     

作为宪法未列举权利的学术自由——美国最高法院的判例与法理

学术自由是否是一个法律概念、一项法定权利,历来是一个问题.在美国法上,学术自由作为大学和教师管理核心学术事务的权利,是一项由最高法院创制的宪法未列举权利.美国早期的学术自由依附于契约权利,体现了一种大学内部政策,即大学管理者在规章制度范围内通过签订契约而赋予教师的自由权.在“学术自由第一案”——Sweezy案——中,最高法院援引宪法第一修正案规定的言论自由权,将学术自由提升为一项值得宪法保护的价值,并指出其基本内涵是自主决定“谁来教、教什么、怎么教、谁被教”;在Keyishian判决中,法院迸一步明确学术自由是“第一修正案的特殊关注”,将其纳入了宪法权利话语体系之中.至Grutter判决,最高法院肯定了在高等教育领域,学术自由是一项独立的、未列举的宪法权利,并可先于其他宪法权利受到保护.相应地,对大学学术性事务的决定,法院必须在宪法规定的范围内给予尊重;尊重的程度,取决于决定是由什么样的主体做出的、需多大程度的学术技能、意识形态中立与否以及是否危害到了别的权利.     

左右同源:新文学史上的新写实主义

在中国新文学史上,持续存在于1920年代之后约半个世纪的新写实主义文艺思潮,不仅包括左翼无产阶级的革命现实主义、社会主义现实主义,也包括一直被忽略的右翼的三民主义写实主义。左右两种新写实主义理论,尽管服务于各自所属政治集团的意识形态竞争需要,却都是源于20年代的苏联和日本,源于相同的革命政治思维和文学工具性思维。     

债权人对债务人延期其债权能否行使代位权——以三段论法中之小前提为观察点

债权人代位权制度起源于法国的习惯法中,因该制度行使简捷便用,故其存在仍有一定的意义。“怠于行使权利”作为代位权构成要件之一的法理,在于权衡债权人的期待利益与债务人管理自己财产之自由相冲突的结果。对此,从三段论法上,笔者对如何将案例事实归摄于构成要件之特征构成小前提,予以分析,并认为化解实务上和学说上的矛盾,应该运用法学方法论,以避免人治的擅断。     

A Comparative Discussion of the Gendered Implications of Cash-for-Care Schemes: Markets, Independence and Social Citizenship in Crisis?

There are moves across many countries away from state-led provision of services for disabled people towards cash-based systems, which have been welcomed by disabled people as increasing choice and control over services and support, and increasing independence and social participation. However, feminist scholars have long warned about the implications of commodifying care for women, and the possible consequences of substituting cash for services for social citizenship have remained underexplored, for both disabled people generally, disabled women and mothers more particularly, and for personal assistants/care workers. This article will attempt to address that gap by carrying out a comparative literature review and policy analysis of the role of policy development and outcomes in cash-for-care schemes, looking comparatively across policy developments in several countries, as well as developed welfare states beyond Europe to examine: (a) the impact of the tensions between various governance levels, particularly local and national government; (b) the gendered impact of such policies on (for example) gendered divisions of paid and unpaid work, citizenship and social participation; (c) the impact such policies have, or are likely to have, on different groups of men and women across the life course and across different social and economic groups; and (d) how such policies can contribute to the well-being and/or detriment of different groups of women (and men) within different social, political, economic and historical contexts.

An estimation of distribution algorithm for lot-streaming flow shop problems with setup times

Lot-streaming flow shops have important applications in different industries including textile, plastic, chemical, semiconductor and many others. This paper considers an n-job m-machine lot-streaming flow shop scheduling problem with sequence-dependent setup times under both the idling and no-idling production cases. The objective is to minimize the maximum completion time or makespan. To solve this important practical problem, a novel estimation of distribution algorithm (EDA) is proposed with a job permutation based representation. In the proposed EDA, an efficient initialization scheme based on the NEH heuristic is presented to construct an initial population with a certain level of quality and diversity. An estimation of a probabilistic model is constructed to direct the algorithm search towards good solutions by taking into account both job permutation and similar blocks of jobs. A simple but effective local search is added to enhance the intensification capability. A diversity controlling mechanism is applied to maintain the diversity of the population. In addition, a speed-up method is presented to reduce the computational effort needed for the local search technique and the NEH-based heuristics. A comparative evaluation is carried out with the best performing algorithms from the literature. The results show that the proposed EDA is very effective in comparison after comprehensive computational and statistical analyses.
