1董事薪酬、CEO薪酬与公司业绩--合谋还是共同激励?显示文摘本文从中国沪深两市观测到的上市公司中CEO和董事薪酬的趋同现象,综合代理理论和乘员理论等多理论基础,基于薪酬激励和公司治理绩效的关系,考察了董事与CEO之间的合谋、单边激励和共同激励等复杂关系。论文采用2005-2007年度我国上市公司样本池数据,通过混合回归、固定效应回归和敏感性分析等实证检验发现,我国董事与CEO薪酬激励已初步与公司业绩挂钩,但是研究揭示CEO激励走在董事绩效激励前面,董事激励不足问题突出。进一步的研究发现上市公司中CEO薪酬与公司业绩正向相关,董事薪酬对公司业绩没有显著影响;结论认为我国上市公司中董事与CEO关系并非简单合谋或共同激励关系,而是处于CEO选择合适角色或监控得当,董事仍持代理角色,并且其战略指导要弱于监控作用的'单边激励'状况。杨青 高铭 Besim Burcin Yurtoglu 2009金融研究2009,,6:54
2中国上市公司CEO薪酬存在激励后效吗?显示文摘与以往纯粹基于代理理论研究CEO薪酬激励问题不同,本文同时考虑乘员理论和制度理论等,从多视角研究上市公司治理绩效。我们采用2005~2008年沪深上市公司面板数据,按全样本、私人与国有控股、国有控股与集体等对照组进行混合回归(Pooled Regress)分析,研究证实中国上市公司CEO薪酬激励与公司业绩显著正相关,董事会部分特征与薪酬机制设计相关;被激励后的CEO在外部治理环境监控下会进一步改善公司业绩,产生激励后效,股权集中度有正向促进作用,但董事会特征与激励后效无关。研究揭示目前董事会受制于代理问题,致力于改善CEO薪酬激励不足,公司业绩改善主要来自于政策、制度变革等外部公司治理,尤其国有控股公司制度改革效应和乘员主义突出,但董事会内部绩效治理仍较弱;这对改善中国CEO薪酬机制设计及内部治理具有积极意义。论文进一步采用固定效应回归(Fixed-effectRegress)、两阶段最小二乘回归法(Two Stage Least Squares Regress)和薪酬灵敏度分析后依然支持该结论。杨青 黄彤 Steven TOMS Besim Burcin YURTOGLU 2010金融研究2010,,1:41
3我国董事会职能探寻:战略咨询还是薪酬监控?显示文摘董事会究竟发挥何种作用一直是公司治理争议的焦点问题。本文采用董事会权能对战略咨询和监督控制的双路径结构方程模型(Structure Equation Model,SEM),提出董事会的监控作用表现为以薪酬激励监督CEO为间接手段来改善公司业绩;战略咨询则体现为董事会权能对公司业绩的直接贡献。以中国2005~2007年上市公司样本的测试结果表明:国资委、地方与中央国有控股公司等的董事会薪酬监控作用显著,表现为改善董事和CEO激励不足,'薪酬激励效应'突出,董事权力和治理效果逐年改善,但其战略咨询的治理任务有待加强;私人控股公司董事会的战略和监督二元作用初步凸显,但存在'薪酬挤出效应',公司治理状况呈弱化趋势,CEO监管与激励有待改善。杨青 薛宇宁 YURTOGLU Besim Burcin 2011金融研究2011,,3:21
4公司复杂性、最优董事会及其独立性选择显示文摘当前各国公司治理都实施统一的董事会治理监管,然而公司经营环境复杂,最优董事会是否是内生性的争论成为近年来公司治理关注的焦点。本文以CEO寻租空间、监督成本等构建最优董事会抉择模型,研究发现:治理成本的存在,使得CEO寻租空间对董事会规模和独立董事比例有积极影响,而监督成本对二者有负面影响;从边际治理成本角度,最优董事会与其独立性存在一定程度的替代性。我国1999~2008年上市公司实证研究发现:一定监管条规下,最优规模与独立性的替代假说成立,鉴于公司经营差异性,僵化的监管制度将提升治理成本,造成董事会效率低下。由此,建议监管机构从治理执行效果出发,考虑最优董事会的相机抉择行为,采用柔性化的监管条规,提高公司治理绩效。杨青 朱晓洋 B Burcin Yurtoglu 方悦平 2012金融研究2012,,8:11
5Gastrointestinal complications after kidney transplantation显示文摘Gastrointestinal complications are common after renal transplantation,and they have a wide clinical spectrum,varying from diarrhoea to post-transplant inflammatory bowel disease(IBD).Chronic immunosuppression may increase the risk of post-transplant infection and medication-related injury and may also be responsible for IBD in kidney transplant re-cipients despite immunosuppression.Differentiating the various forms of post-transplant colitis is challenging,since most have similar clinical and histological features.Drug-related colitis are the most frequently encountered colitis after kidney transplantation,particularly those related to the chronic use of mycophenolate mofetil,while de novo IBDs are quite rare.This review will explore colitis after kidney transplantation,with a particular focus on different clinical and histological features,attempting to clearly identify the right treatment,thereby improving the final outcome of patients.Rossella Gioco Daniela Corona Burcin Ekser Lidia Puzzo Gaetano Inserra Flavia Pinto Chiara Schipa Francesca Privitera Pierfrancesco Veroux Massimiliano Veroux 2020World Journal of Gastroenterology2020,26,38:6
6Treatment modalities for hypersplenism in liver transplant recipients with recurrent hepatitis C显示文摘Hepatitis C is the most common indication for orthotopic liver transplantation in the United States. Unfortunately, hepatitis C recurs universally in the transplanted liver and is the major cause of decreased graft and patient survival. The combination therapy of interferon and ribavirin has been shown to be the most effective therapy for recurrent hepatitis C. However, pre-and post-transplant hypersplenism often precludes patients from receiving the antiviral therapy. Splenectomy and partial splenic embolization are the two invasive modalities that can correct the cytopenia associated with hypersplenism. In this report we review the two treatment options, their associated outcomes and complications.Lena Sibulesky Justin H Nguyen Ricardo Paz-Fumagalli C Burcin Taner Rolland C Dickson 2009World Journal of Gastroenterology2009,15,40:5
7Retinal vessel diameters and their correlation with retinal nerve fiber layer thickness in patients with pseudoexfoliation syndrome显示文摘AIM: To compare retinal artery-vein diameters(RAVDs)of patients with pseudoexfoliation(PSX) syndrome with healthy controls and investigate the correlations between retinal nerve fiber layer(RNFL) thickness parameters and RAVDs.METHODS: Seventeen eyes with PSX and 17 eyes of age-matched controls were included in the study. All participants underwent routine ophthalmological examination, Humphrey visual field and RNFL examination by using Stratus OCT. Retinal images were obtained by using a retinal camera(Topcon 501X).RAVDs were measured from inferior nasal, inferior temporal, superior nasal and superior temporal arcuates by using IMAGEnet software. Superior, inferior, nasal,temporal and average RNFL thicknesses were recorded.RAVDs and RNFL parameters in groups and correlations were analyzed by Mann-Whitney U and Spearmann correlation tests.RESULTS: Only inferior quadrant and average RNFL thickness were detected thinner in the PSX group compared with control group(P =0.009, P =0.038,respectively). No statistically significant difference regarding RAVDs was found between two groups.CONCLUSION: RAVDs seems to be comparable in the PSX and control group. RNFL is thinner in the inferior quadrant in the PSX group. RNFL thickness and RAVDs show significant correlations in both groups. This correlation doesn't seem to be specific to PSX.Mehmet Cuneyt Ozmen Zeynep Aktas Burcin Kepez Yildiz Murat Hasanreisoglu Berati Hasanreisoglu 2015International Journal of Ophthalmology(English edition)2015,8,2:3

9Digitally reinforced hematoxylin-eosin polarization technique in diagnosis of rectal amyloidosis显示文摘AIM:To investigate the efficacy of the digitally reinforced hematoxylin-eosin polarization(DRHEP)technique for detection of amyloidosis in rectal biopsies.METHODS:One hundred hematoxylin-eosin(HE)stained rectal biopsies with Congo-red(CR)-positive amyloid depositions and 50 control cases with CRnegative amyloid-mimicking areas were scanned blinded to the CR results for amyloid depositions under both bright and polarized light,and digitally photographed using the DRHEP technique,to accentuate the faint birefringence observed in HE slides under polarization.The results of DRHEP and HE evaluation were statistically correlated with CR polarization results with respect to presence and localization of amyloid deposits as well as amyloid types.RESULTS:Amyloid deposits showed yellowish-green birefringence by DRHEP,which allowed identification of amyloidosis in 41 HE-unsuspected cases(P=0.016),31 of which only had vascular deposits.True positivity was higher,and false negativity and positivity were lower by DRHEP,compared to evaluation by HE(69%,31%,and 0.8%vs 33%,67%,and 33%,respectively;P<0.0001).The sensitivity,specificity,accuracy,and positive and negative predictive values for DRHEP were69%,98%,78.6%,98.5%,and 61.25%,respectively.Reasons for DRHEP false negativity were presence of extensive background birefringence in 12 cases,absence of CR birefringent vessel in 3 cases,and missing of the tiny deposits in 9 cases,which could be improved by experience,especially in the latter case.No correlation was found between age,gender,sites of deposits,or amyloid types.CONCLUSION:The DRHEP technique improves diagnostic accuracy when used as an adjunct or a prior step to CR staining,especially for cases with limited tissues for further analysis.Basak Doganavsargil Gulruh Emiroglu Buberal Huseyin Toz Banu Sarsik Burcin Pehlivanoglu Murat Sezak Sait Sen 2015World Journal of Gastroenterology2015,21,6:2
