    劳动合同是商品经济和社会化大生产的产物,是市场经济条件下劳动关系确立的基础。无固定期限劳动合同是劳动合同的重要类型。它事关广大劳动者和用人单位的实际利益,对劳动关系的和谐与稳定影响甚大。2008年生效的《中华人民共和国劳动合同法》对无固定期限劳动合同进行了制度重构,赋予其“保护劳动者的合法权益,构建和发展和谐稳定劳动关系”的价值目标,但结果并不理想。用人单位怨声载道,裁员潮此起彼伏,许多劳动者因而失业。现行的无固定期限劳动合同制度并没有有效发挥其应有的制度价值。因而,将无固定期限劳动合同的价值目标与法条进行对比,系统地审视我国无固定期限劳动合同制度,寻找其存在的弊端并加以更正和完善,是当前一项...The labor contract is the outcome of the commodity economy and large-scale socialized producing, as the basis upon which labor relations can be established under the condition of market economy. Non-fixed-term labor contract, as an important type of labor contracts, is related to the practical interests of broad masses of workers and employers, and affects the harmony and stability of labor relati...学位:法律硕士院系专业:法学院法律系_法律硕士(JM)学号:1292006115061

    高等教育学学科属性刍议

    Get PDF
    高等教育研究的“学科“与“领域“之争是一个久争不决的问题。从学科的本源判断,高等教育学学科的合法性来源于高等教育发展规律的特殊性。作为教育活动的特殊组成部分,高等教育活动具有一些传统教育学无法解释的特殊问题和特殊规律。那么,作为研究高等教育活动特殊问题与特殊规律的学科,高等教育学应当成为教育学的组成部分。[1]在这个高等教育学学科属性的争议焦点,集中在如何判断当前学科建设过程中出现的一些学理问题。比如,高等教育学能否建立一套比较成熟的学科理论体系,以及高等教育学是否具备独特的研究范式或研究方法。如果以这两方面问题为标准,那么当前我国高等教育学的学科体系尚不成熟。实际上,即使对传统上比

    我国的银行按揭贷款业务伴随着房地产业的发展而迅速发展,现在已经成为房地产业的支柱之一,极大地激活了整个房地产市场。从最初只有中国银行、中国建设银行、中国工商银行等少数几家国有银行小心翼翼的进入按揭领域,到现在几乎各家银行均有开展,并且按揭规模越来越大,相关金融产品例如转按揭业务、二次按揭业务等越来越丰富,竞争越来越激烈。按揭在我国是新生事物,随着商品房按揭实务的开展,相关的法律问题也凸现出来。解决这些问题首先要明确何为按揭、按揭的立法状况、法律性质等诸问题。因此,对按揭制度进行研究颇具理论与实践意义。按揭是一种渊源于英国的古老的担保方式,远在十二世纪中叶就存有其雏形,历经将近9个世纪的发展,从...With the development of the real estate industry, the number of the housing mortgage loan in China has been increasing rapidly and has become one of the backbones of the real estate industry. There were few commercial banks who provided the service of housing mortgage loan in the beginning, but now almost every bank provides the service and the related financial products like mortgage refinance an...学位:法律硕士院系专业:法学院法律系_民商法学(含劳动法学、社会保障法学)学号:20040814

    蔡英文上台后台湾对外关系前景分析

    Get PDF
    蔡英文于2016年上台后,两岸关系面临诸多变数,这种变数不仅仅来自于具体的两岸事务中,还体现在国际社会上,蔡英文上台前后已经多次阐述了其"外交"政策,其对外交往也在逐渐展开。本文在回顾台湾对外交往历程的基础上,具体分析了蔡英文的对外政策,辅以其具体的政策实施情况对台湾的对外前景做大概预测。本文认为,期望"让台湾走向世界"的蔡英文由于国际现实状况及其没能在两岸关系上做出良好的表态,其"国际空间"很难得到扩大,具体的对外交往或许也只能以严肃的议题开始,以荒谬的闹剧结束

    省际高等教育生均支出的面板回归分析

    生均教育经费支出水平是衡量教育资源充沛与否的重要指标。根据1999年到2008年相关数据分析,多数省份普通高等教育生均教育经费支出水平下降;省际生均支出水平两极分化现象凸显;在高等教育大众化背景下,省域社会产业结构对普通高等教育生均支出水平影响最大,政府财政能力其次。因此,各省应针对社会经济发展需要和本省高等教育基础,制订和完善生均教育经费保障体系。教育部哲学社会科学重大课题攻关项目(10JZD0038

    目的初步评估贝壳多孔羟基磷灰石基骨修复材料及该材料和骨形成蛋白-2联合应用引导比格犬牙周组织再生的效果。方法选取18月龄比格犬6只,牙周基础治疗后1周,在下颌第二、三、四前磨牙,建立急性牙周骨缺损模型,依照分组情况进行不同治疗。实验组(T组)植入骨修复材料和骨形成蛋白-2;阴性对照组(nC组)植入骨修复材料;空白对照组(bC组)不植入任何材料。实验设计采取同颌同名牙对照,同一只比格犬的3对同颌同名牙分别为:空白对照组和阴性对照组,阴性对照组和实验组,空白对照组和实验组。术后12周,处死动物,MICrO-CT检查并对数据进行统计学分析。结果材料植入后,未见材料溢出,植入局部和全身都未见明显不良反应。3组缺损都有一定程度骨再生,以T组再生组织量最多,bC组最少。MICrO-CT结果显示:T组、nC组和bC组的骨再生平均高度为(4.50±0.47)MM(、1.75±0.42)MM和(0.87±0.31)MM。nC组和bC组相比,差异有统计学意义(P<0.05)。T组与nC组和bC组相比,差异均有统计学意义(P<0.05),且有临床意义。结论贝壳多孔羟基磷灰石基骨修复材料和骨形成蛋白-2联合应用于比格犬,可以获得更好的引导组织再生效果。Objective To evaluate the ability of core-shell hydroxyapatite bone graft material alone and combined with bone morphogenetic protein 2(BMP-2) in periodontal regeneration treatment in dogs.Methods Thirty-six defects were created in six 18-months male beagle dogs at the sites of the second,third and fourth mandibular premolars one week later after the dogs were treated with non-surgical periodontal therapy.Different treatments were carried out according to which group the teeth belonged.There are 3 groups.The test group(group T) was treated with core-shell hydroxyapatite bone graft material combined with BMP-2;the negative control group(group NC) was treated with core-shell hydroxyapatite bone graft material alone and the blank control group(group BC) was treated with no graft material.When a tooth was selected into one of the 3 groups randomly,the tooth with the same name on the other side in the same jaw was selected into another group.6 defects in the same dog were made and divided into 3 groups.The animals were sacrificed 12 weeks after surgery and analyzed by Micro-CT.Results There was no adverse reaction after material was planted.There were bone regenerations in all groups.Group T got the best bone regeneration while group BC got the least bone regeneration.The biggest height of bone regeneration for group T,group NC and group BC were(4.50±0.47) mm、(1.75±(0.42) mm) and(0.87±0.31) mm according to Micro-CT evaluation.There were statistical difference of bone regeneration height between group NC and group BC.There were statistical differences between group T and group NC and between group T and group BC.Conclusion More periodontal tissue regeneration could be got when core-shell hydroxyapatite bone graft material was used with bone morphology protein 2.南京市医学科学技术发展专项项目(ZKX07022);天津市生物医学材料重点实验室开放课题;南京市医学科技发展青年人才启动项目(QYK10166

    基于催化剂多活性中心分工协同作用可活化两种或多种反应物,本研究工作以一种新的制备策略对贵金属-过渡金属-过渡金属氧化物催化剂进行合理设计,构筑金属与金属氧化物双活性中心。结果发现,贵金属负载于过渡金属/过渡金属氧化物(nM-TM/TMO)结构的催化剂在加氢反应中具有优异的催化活性。同时,热处理方法可有效调控催化剂微观结构,并对此构效关系进行了较为深入的研究。As synergic multiple active sites catalysts can theoretically activate two or more reactant or substrates simultaneously resulting in significantly increase of activity and stability of catalysts, we herein develop a novel catalysts preparation strategy to design and construct noble metal-transition metal-transition metal oxide(NM-TM/TMO) to form bi-active catalytic sites.The experimental results show that such a catalyst has excellent performance in catalytic hydrogenation, e.g.aromatic compounds hydrogenation as the case studies.It was also found that the nanostructure of catalyst can be tuned via thermal treatments, which are investigated and the relationship between structure and activity is explored to some extent.国家自然科学基金项目(20973140;201106118;21303140)~
