The Influence of Political Connection and Institutions to the Performance and Bank Loans of Private Listed Companies

我国有着不同于西方发达国家的制度背景和政治制度，政府对市场的管制力度较大，上市公司的高管具有一定的政治背景，其中国有企业本身大股东的政府背景性质，其政治关联很可能是与生俱来的，而民营企业政治关联的形成则具有主动性。改革开放以来，民营经济不断发展壮大，己成为我国经济增长的主要推动力量，因此，研究政治关联对民营公司的影响这一问题在中国更具有现实启发意义。 本文以民营上市公司的高级管理人员是否是前任或现任的政府官员、人大代表或政协委员来衡量公司是否具有政治关联，选取2004年—2008年中国沪深两市所有A股民营上市公司为样本，实证研究了政治关联与制度环境对民营上市公司经营绩效和银行贷款的影响。研究...Chinese current institution and political system are different from the Western developed countries. Under this system, many executives of private listed companies are relevant to politics. Therefore the study of political influence of private companies related to this issue in China is more realistic instructive. This paper focuses on whether the company has the political connection, which measu...学位：管理学硕士院系专业：管理学院财务学系_财务学学号：1762007115174

High-efficiency deflection of high-energy negative particles through axial channeling in a bent crystal

Deflection due to axial channeling in a silicon crystal bent along the [111] axis was observed for 150 GeV/c negative particles, mainly π− mesons, at one of the secondary beams of the CERN SPS. The whole beam was deflected to one side with the efficiency of about 90% and with the peak position at the bend crystal angle α=43 μrad. The deflection occurs mainly due to doughnut scattering of above-barrier particles by the atomic strings of the crystal. However, due to a high probability of particle recapture into bound states with the atomic strings their contribution to the deflection should be about 15% for our case according to simulation results

High-Efficiency Deflection of High-Energy Protons through Axial Channeling in a Bent Crystal

Beam deflection due to axial channeling in a silicon crystal bent along the [111] axis was observed with 400  GeV/c protons at the CERN Super Proton Synchrotron. The condition for doughnut scattering of protons by the atomic strings of the crystal was attained. Such a condition allowed one to observe a beam deflection of 50  μrad with about 30% efficiency. The contribution of hyperchanneled states of protons to the observed beam deflection was less than 2% according to simulation results

A Survey on Executive Compensation , A Study on Influencing Factors of Executive Compensation in Listed Companies

企业要想保持稳定持续的发展，就离不开一个公平合理的薪酬激励制度，同时这也是全体员工都非常关心的一个问题。全球经济一体化趋势愈演愈烈，在经受了2008年席卷全球的金融危机之后，上市公司高管薪酬以及他们过高的薪酬又一次成为众多媒体的焦点。尽管对于高管薪酬激励的研究由来己久，并且已经形成了相当多的研究成果，但是无论在理论界还是实践中，对于高管薪酬的关注却是从未减少过。一方面是高管薪酬问题会一直伴随着企业发展，是老生常谈且十分重要的企业机制，另一方面也说明了现有的研究还不能满足实践中的需求，还存在着种种不足和局限。 本文以我国2005-2010年A股上市公司的高管薪酬为对象，多角度、多层次地调查我国...Only a few other issues in the history of the modern corporation have generated the amount of fury as the executive compensation. While workers real income stagnated or even dropped over this period, there has been unprecedented growth in total pay for top executives. This decoupling of pay and performance at the very top caused considerable concern and public outcry, renewing the calls for compen...学位：管理学硕士院系专业：管理学院财务学系_财务学学号：3212009115059

High-EfficiencyVolume Reflection of an Ultrarelativistic Proton Beam with a Bent Silicon Crystal

The volume reflection phenomenon was detected while investigating 400 GeV proton interactions with bent silicon crystals in the external beam H8 of the CERN Super Proton Synchrotron. Such a process was observed for a wide interval of crystal orientations relative to the beam axis, and its efficiency exceeds 95%, thereby surpassing any previously observed value. These observations suggest new perspectives for the manipulation of high-energy beams, e.g., for collimation and extraction in new-generation hadron colliders, such as the CERN Large Hadron Collider
