上颌中切牙多孔金属牙桩的设计及有限元分析

为了设计一种表面带有多孔结构的金属牙桩,比较多孔金属牙桩和铸造桩修复上颌中切牙后的应力分布,采用 上颌中切牙建立多孔金属牙桩修复后的三维有限元模型,牙桩的表面设计成孔隙率分别为15. 5%,26. 2%,40. 2%, 59. 2%的多孔结构,并进行有限元分析。分析表明随着牙桩表面多孔结构的孔隙率增加,牙根上的最大主应力增加,牙 桩内部实心结构和外部多孔结构的等效应力增加,多孔结构的等效应力大于实心结构的等效应力。研究得出结论：孔隙 率可以调整降低金属牙桩表面的弹性模量和抗压强度,有利于保护牙根。     

韩非论臣

韩非认为君臣之间毫无感情可言,有的只是利益的争夺。＂明主＂要能严格区分手下臣子并针对不同类型的臣施之以不同的策略。他将君主手下的臣子进行分类,并针对不同的类型指出了不同的控制及治理措施。     

应对方式与社会支持对高校毕业生就业压力的影响

研究采用大学生就业压力问卷、社会支持问卷以及应对方式问卷对高校即将毕业的大学生进行随机问卷调查发现:采取不同应对策略的毕业生,感受到的就业压力存在显著差异,其中采取成熟型应对策略的大学生感受到的压力最低,其次是中间型应对策略的大学生,而不成熟型应对策略的大学生感受到的压力最大;社会支持对就业压力有一定影响,但影响不显著.大学生的就业压力可以通过改进压力的应对方式加以缓解,而社会支持的作用则有待进一步改进.

基于有限元法的脱水压榨机强度校核

为了保证隧道洗衣机有良好的脱水性,根据相关规范,设计了符合隧道式洗衣机的脱水压榨机,综合运用实体单 元和连接单元,建立了包括上下横梁、中间四根拉杆的有限元模型,并利用ABAQUS软件对于模型进行网格划分,施加材 料属性以及必要的约束和静力载荷,最后进行了应力分析强度校核。结果表明在额定工况下,从应力云图以及位移云图 验证了脱水压榨机主要部件应力均在安全范围内,其强度均满足要求。     

从英语重音看汉腔英语

英语节奏主要体现在重读音节和轻读音节的交替变化中,元音在重音的指派下具有明显的强/弱对立、长/短对立和清晰/模糊对立。汉腔英语是一种偏离英语节奏规范的变体,表现在随意添加重读,惯用强读式,回避连读,导致重读音节和轻读音节大量中和化,元音时长扭曲,节奏配置失调。因而对中国英语学习者来说,树立并强化英语节奏的重音意识,注重重读音节和轻读音节之间的区分度,无疑是克服汉腔英语、提高英语听说能力的有效途径。     

媒体监督公司治理的实证研究

随着国内改革环境的逐步宽松和市场竞争的加剧,为了赢得社会声誉和获得商业利益,媒体有动力去监督公司中存在的治理问题。在本文所选取的96个研究样本中,60.42%存在公司治理问题的企业都在证监会正式介入调查前受到过媒体的质疑和负面报道,说明媒体并非事前"缄默无语"、事后"言辞铿锵",而是积极地扮演了资本市场监督者的角色;基于成本与收益的权衡考虑,媒体会选择性质严重和涉及金额大的公司治理问题进行负面报道。本文的研究结论一方面为媒体在转型经济国家发挥公司治理监督者的作用提供了证据,另一方面也分析了在法律制度和市场化尚不完善的情况下,影响媒体发挥监督作用的因素,依此提出了若干政策建议。     

Emotional labour and emotional exhaustion: Interpersonal and intrapersonal mechanisms

Abstract

In some occupations, particularly in the service sector, dealing with patients or clients may require an employee to pretend to have emotions that they do not really have, or to actually experience required emotions. The regulation of emotion can be either automatic or controlled. This study extends research on the consequences and processes of emotional labour in two ways. First, it examines how the use of different emotion regulation strategies with patients relates to doctors’ emotional exhaustion. Second, it tests two mechanisms that may explain those relationships. A survey of 345 general practitioners (GPs) working in a large urban community in Spain was conducted for the study. Based on Côté's (2005) social interaction model, GP satisfaction with the responses of their patients was tested as a potential interpersonal mediator between their use of automatic, surface, and deep emotion regulation strategies and their emotional exhaustion. Psychological effort was tested as a potential intrapersonal mediator in the same pathway. Regression analysis indicated that emotion regulation was associated with GP emotional exhaustion when it was performed automatically, but that it had a positive and a neutral association when it was performed using surface and deep acting respectively. The mediating role of interpersonal and intrapersonal factors helped explain the differential associations between the GPs’ emotion regulation strategies and their emotional exhaustion.

What do stress tests test? Experimentation,demonstration, and the sociotechnical performance of regulatory science

After their successful introduction during the 2007–2009 financial crisis, central bank stress tests were adopted as a fixture of international banking supervision. However, in recent years a new normal has emerged where banks are expected to pass the tests, raising questions about the tests’ usefulness and legitimacy. Combining a dramaturgical interpretation of regulatory science with the idea of performativity in the sociology of finance, this article understands stress tests as a sociotechnical Goffmanian performance. With a focus on the Bank of England’s program, the paper argues that the Bank’s decision to make their tests “predictable” is an attempt to shore up central bank legitimacy by constraining regulatory discretion. This is accomplished through the use of calculative and procedural stage management techniques which allow the Bank to control the contingency of the testing process while demonstrating its objectivity. Nevertheless, the conclusion suggests that in the context of low levels of trust in central banks, routine declarations of “all clear” may undermine public confidence in the tests’ credibility and necessity. The study draws on 20 interviews with high-level regulators, financial practitioners and other stakeholders in the Bank of England’s stress tests.
