Discussion of the Impact of Capital Market on Corporate Governance of Listed Companies

公司治理问题对于完善一国的市场体系具有十分重要的意义。由于各国的政治、经济、文化及企业制度的发展轨迹不同，我们不可能找到一种普遍适用的公司治理模式。我国处于计划经济体制向市场经济体制转轨时期的公司治理改革与西方发达国家的公司治理改革，甚至与其它同样处于经济转轨时期国家的公司治理改革都存在着截然不同的特点。因此，要解决我国上市公司治理问题就必需从我国转轨经济这个最大的国情出发，同时结合我国资本市场的其他重要特点。由于资本市场是上市公司治理最重要的外部环境之一，它对公司治理具有至关重要的作用，因此本文选择从资本市场对公司治理的作用对我国转轨经济时期的上市公司治理问题进行研究。根据资本市场上投资主体...Corporate governance is very significant for perfecting the market system of a country. Because of the difference in polity, economy, culture and track of company system, we can find out a model for corporate governance which is suitable for any countries. The transit from planned economy to market economy complicates the corporate governance revolution of listed companies.

近海生态系统碳汇过程、调控机制及增汇模式

海洋是地球上最大的碳库,发挥着全球气候变化缓冲器的作用.蓝色碳汇,简称蓝碳,即由海洋生态系统捕获的碳(主要是有机碳),是海洋储碳的重要机制之一.; 蓝碳最初认识的形式是可见的海岸带植物固碳.其实之前没有得到足够重视的、看不见的微型生物(浮游植物、细菌、古菌、病毒、原生动物)占海洋生物量90%; 以上,是蓝碳的主要贡献者.中国陆架边缘海占国土总面积的1/3,碳汇潜力巨大,亟待研发.本文以近海生态系统碳汇过程、调控机制及增汇模式为主线,论述; 了近海生态系统结构与碳循环功能特征、碳汇形成过程与机理,并结合近海碳汇在沉积记录中的地史过程演变探讨了自然过程和人类活动对碳汇的可能影响,展望了; 碳汇工程在增加近海海洋储碳能力方面的应用前景.国家重大科学研究计划项目; 国家重点研发计划项目; 国家自然科学基金项目; 国家海洋局全球变化与海气相互作用专项项

TiO_2直接电解还原过程的研究

采用SEM、EDS、XRD等方法对TiO2直接电化学还原产物进行分析,指出TiO2电极的还原是从外向内由高价到低价再到金属逐步进行的。对还原过程中电流、还原气相产物的分析结果表明:还原过程电流效率低,并且电流效率随电解时间延续而降低,阳极产物CO、CO2与阴极中间产物Ca发生副反应以及副反应产物炭黑造成电流短路是电流效率低的主要原因。提高电流效率的途径有两条:一是增大阴、阳极间距,减小副反应的发生;二是使电解池表面熔盐不断导出,或采取某一隔离措施,使副反应产生的炭黑在阴、阳极之间不造成电流短路

PROPAGULE DEVELOPMENT OF BRUGUIERA GYMNORRHIZA UNDER DIFFERENT TIDAL AND SEDIMENTAL CONDITIONS

采用模拟半日潮系统研究了水渍和底质条件对红树植物木榄(Bruguieragymnorrhiza)的影响。水位上升和淹水时间延长导致红树林底质的酸化,且壤质底质的酸化比沙质底质严重;对木榄的萌苗速度无显著影响;促进木榄的早期生长,尤其是导致最初2个月茎高生长的增加,但后2个月木榄的相对生长率受抑制;地下部/地上部生物量比值下降,沙质底质中尤为如此;粗根比例明显增加;叶绿素含量增加,叶绿素a/b比值无显著影响;叶面积减少;壤质底质上生长植株的叶片气孔密度增加,沙质底质无显著变化;根N含量无显著变化,P含量显著增加。Due to their special habitats in intertidal zones along tropical and subtropical coastlines, mangroves are influenced by the conditions of water depth, duration and sediment types.To investigate responses in early development of Bruguiera gymnorrhiza including propagule establishment and seedling growth to tidal and sedimentary conditions of simulated semi-diurnal tidal systems, a 4-month experiment was set up.Mature propagules of B.gymnorrhiza were planted respectively in pots containing silty and loamy-sandy soils collected from Mai Po and Sai Kung mangrove forests in Hong Kong.Four plastic tanks(85 cm in length, 64 cm in width and 50 cm in height) were used in this experiment mimicking 4 combinational conditions, i.e.high water level with coarse soil(HC), high water level with fine soil(HF), low water level with coarse soil(LC), and low water level with fine soil(LF).Artificial seawater in salinity of 15 was pumped into and out of the tanks in designed intervals to simulate daily semidiurnal tidal phases including two floods and two ebbs.Daily inundation time of high and low water treatments was 16 h and 4 h, respectively.Water level of HC and HF was 30 cm above soil surface, and 0 cm for LC and LF.Each treatment was triplicate. Under both high and low water levels, all propagules established and grew well in the experiment.As water level and inundation time increased, the acidity increased, which is higher in fine sediment than that in coarse ones.High acidity would not favor the plant growth.The establishment of B.gymnorrhiza propagules was not significantly influenced by the condition change.Early growth especially the stem height increments was stimulated by the increases in water level and inundation time in the first two months then relative growth rates slowed down in the second two months.In addition, as water level and inundation time increased, the ratio in biomass below-ground/above-ground significantly decreased, especially in coarse sediment and the percentages of coarse roots, P contents in roots and chlorophyll contents in leaves tended to increase.Other physiological parameters such as carotene and stoma density were also analyzed, along with detail discussions on the relationship of water depth, inundation length and sediment type to the plant development.国家自然科学基金资助项目,40276036和40476040号;; 福建省自然科学基金项目,D0410006号;; 香港环境保护基金资助项目,9210007

男护士职业发展规划与管理新进展

随着现代医学技术的高速发展，单一性别的女性护理队伍格局也随之改变，男护士逐渐登上了护理岗位的舞台。男护士面临着很多障碍，因为对中国的人民群众来说，“男护士”还是一个崭新的词汇，因为传统观念的影响、社会舆论的压力以及家庭因素，导致男护士很难长期从事护理岗位，更不会把护理职业作为人生的职业规划目标。如果医院缺乏对男护士的长期培养以及优化晋升机制，护理管理者的管理能力低下，男护士的职业发展得不到支持，会导致其对职业的怠慢，也会导致严重的离职倾向。因此，如何更好地发挥男护士的力量，是对临床护理管理者提出的新的挑战。论文论述了男护士职业发展方向及规划，对男护士的管理进行了探讨，以期为推动男护士的发展提供依据。</jats:p

Aripiprazole versus other atypical antipsychotics for schizophrenia

BACKGROUND: In most western industrialised countries, second generation (atypical) antipsychotics are recommended as first line drug treatments for people with schizophrenia. In this review we specifically examine how the efficacy and tolerability of one such agent - aripiprazole - differs from that of other comparable second generation antipsychotics. OBJECTIVES: To evaluate the effects of aripiprazole compared with other atypical antipsychotics for people with schizophrenia and schizophrenia-like psychoses. SEARCH METHODS: We searched the Cochrane Schizophrenia Group Trials Register (November 2011), inspected references of all identified studies for further trials, and contacted relevant pharmaceutical companies, drug approval agencies and authors of trials for additional information. SELECTION CRITERIA: We included all randomised clinical trials (RCTs) comparing aripiprazole (oral) with oral and parenteral forms of amisulpride, clozapine, olanzapine, quetiapine, risperidone, sertindole, ziprasidone or zotepine for people with schizophrenia or schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS: We extracted data independently. For dichotomous data we calculated risk ratios (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis based on a random-effects model. Where possible, we calculated illustrative comparative risks for primary outcomes. For continuous data, we calculated mean differences (MD), again based on a random-effects model. We assessed risk of bias for each included study. MAIN RESULTS: We included 12 trials involving 6389 patients. Aripiprazole was compared to olanzapine, risperidone and ziprasidone. All trials were sponsored by an interested drug manufacturer. The overall number of participants leaving studies early was 30% to 40%, limiting validity (no differences between groups).When compared with olanzapine no differences were apparent for global state (no clinically important change: n = 703, 1 RCT, RR short-term 1.00 95% CI 0.81 to 1.22; n = 317, 1 RCT, RR medium-term 1.08 95% CI 0.95 to 1.22) but mental state tended to favour olanzapine (n = 1360, 3 RCTs, MD total Positive and Negative Syndrome Scale (PANSS) 4.68 95% CI 2.21 to 7.16). There was no significant difference in extrapyramidal symptoms (n = 529, 2 RCTs, RR 0.99 95% CI 0.62 to 1.59) but fewer in the aripiprazole group had increased cholesterol levels (n = 223, 1 RCT, RR 0.32 95% CI 0.19 to 0.54) or weight gain of 7% or more of total body weight (n = 1095, 3 RCTs, RR 0.39 95% CI 0.28 to 0.54).When compared with risperidone, aripiprazole showed no advantage in terms of global state (n = 384, 2 RCTs, RR no important improvement 1.14 95% CI 0.81 to 1.60) or mental state (n = 372, 2 RCTs, MD total PANSS 1.50 95% CI -2.96 to 5.96).One study compared aripiprazole with ziprasidone (n = 247) and both the groups reported similar change in the global state (n = 247, 1 RCT, MD average change in Clinical Global Impression-Severity (CGI-S) score -0.03 95% CI -0.28 to 0.22) and mental state (n = 247, 1 RCT, MD change PANSS -3.00 95% CI -7.29 to 1.29).When compared with any one of several new generation antipsychotic drugs the aripiprazole group showed improvement in global state in energy (n = 523, 1 RCT, RR 0.69 95% CI 0.56 to 0.84), mood (n = 523, 1 RCT, RR 0.77 95% CI 0.65 to 0.92), negative symptoms (n = 523, 1 RCT, RR 0.82 95% CI 0.68 to 0.99), somnolence (n = 523, 1 RCT, RR 0.80 95% CI 0.69 to 0.93) and weight gain (n = 523, 1 RCT, RR 0.84 95% CI 0.76 to 0.94). Significantly more people given aripiprazole reported symptoms of nausea (n = 2881, 3 RCTs, RR 3.13 95% CI 2.12 to 4.61) but weight gain (7% or more of total body weight) was less common in people allocated aripiprazole (n = 330, 1 RCT, RR 0.35 95% CI 0.19 to 0.64). Aripiprazole may have value in aggression but data are limited. This will be the focus of another review. AUTHORS' CONCLUSIONS: Information on all comparisons are of limited quality, are incomplete and problematic to apply clinically. Aripiprazole is an antipsychotic drug with a variant but not absent adverse effect profile. Long-term data are sparse and there is considerable scope for another update of this review as new data emerges from the many Chinese studies as well as from ongoing larger, independent pragmatic trials
