Changes in Cash Dividends: Sending Performance Signals or Constrainting Agency costs —— In the Perspective of Future Performance

公司未来收益的变化可能是现金股利变化的“因”，也可能是现金股利变化的“果”。前者可以从信号假说的角度解读：当管理层预期未来收益较为乐观时，公司增加现金股利的发放；相反，当管理层预期未来收益不乐观时，公司会减少现金股利的发放。后者可以从自由现金流量代理成本的角度解读：根据Jensen的观点，自由现金流量涉及到公司的代理成本问题，通过对自由现金流存量的调节，现金股利的变化能起到约束公司代理成本的作用，对公司的资金使用效率、外部的审查及监督效用产生影响，最终表现为公司未来收益的变化。两种不同角度的解读，不禁令人产生疑问，现金股利的变化究竟是扮演着什么样的角色？是在信息不对称的情况下，被用来作为传递公...The relationship between the future performance of corporate and cash dividends changes is that the former may be a result of later, while the later may be seen as a result of former also.

On the New Literary Style of Yokoyama Yuta\u27s 横山悠太 : I Am Becoming a Cat

Yokoyama Yuta\u27s I Am Becoming A Cat is a rare cross-boundary masterpiece in the historical pedigree of contemporary cultural exchanges between China and Japan after 1980s. It not only inherited modern Japanese literary tradition since Natsume Soseki\u27s I AM A Cat, but also blended Chinese and Japanese bilingualism to create a new literary style. It is kindred with Natsume\u27s I Am A Cat as well as Lu Xun\u27s Ah Q Diary, and all of the three have tried to pursuit a meaningful "hybridity" of Chinese and Japanese cultures.陶徳民教授古稀記念

基于栖息地风险评价模型的海岸带滩涂湿地风险评价——以闽三角为例

海岸带湿地是生物多样性最丰富、生产力最高、最具价值的生态系统之一。然而近年来,随着城市化和工业化进程的加快,我国海岸带地区的土地利用正发生深刻变化,生态风险凸显。利用2000、2005、2010和2015年的Landsat TM/ETM+和Landsat 8 OLI遥感影像,融合行政区划图与地形图,并引入一个评价多元海洋、海岸带利用对栖息地造成风险的模型,即Integrated Valuation of Ecosystem Services and Trade-offs(In VEST)模型中的栖息地风险评价(Habitat Risk Assessment,HRA),模型评价闽三角海岸带滩涂湿地的生态风险。结果表明:(1)闽三角海岸带滩涂湿地风险以低风险为主;(2)泉州地区的风险面积最大(约4389.91 hm~2),漳州地区最小(约4630.73 hm~2);(3)修正面积影响的情况下,其他建设用地造成的暴露和影响较大,耕地造成的暴露和影响最小。不同区域滩涂湿地风险程度的可视化表达,可以揭示滩涂湿地高风险地区以及高风险的产生原因,便于管理者对滩涂湿地采取精准的保育措施。国家重点研发计划(2016YFC0502900);;福建省科学技术厅民生科技专项(引导性项目)(2017Y6002);;福建省自然科学基金资助项目(2015J01122

Experimental Study of the Abalone Shell on Cataract induced by Oxidative Stress

目的研究石决明提取物对体外培养的晶状体氧化应激性白内障形成的作用及机制。方法离体培养小鼠晶状体,应用不同浓度的石决明提取物预孵育晶状体24h后,加入1mm过氧化氢,继续培养3小时后恢复正常培养,72小时后观察小鼠晶状体混浊程度,测定晶状体组织培养液中的乳酸脱氢酶(LDH)含量,晶状体组织中还原型谷胱甘肽(GSH)含量及超氧化物歧化酶(SOD)活力。结果石决明提取物在1~2 mg/ml浓度范围内减轻氧化应激造成的晶状体混浊,减少晶状体LDH的释放,提高组织内GSH含量和SOD活力。结论石决明提取物可减轻氧化应激白内障的形成,其作用主要与石决明提取物提高内源性抗氧化系统有关。Objective To study the effect of the abalone shell extract on oxidative stress induced cataract formation and its mechanism in cultured mouse lens in vitro. Methods The cultured mouse lens were pretreated with the abalone shell extract in different concentrations for24 hours,and then 1mm hydrogen peroxide was added and continued incubating for 3 hours,and they were changed to normal culture media.After 72 hours,the opacity of each lens was observed under an anatomical microscope,the content of lactate dehydrogenase( LDH)leakages,the content of the reduced glutathione( GSH) and activity of superoxide dismutase( SOD) in lens tissue were assayed. Results Abalone shell extract in the concentration range of 1 ~ 2 mg / ml reduced the lens opacity caused by oxidative stress,alleviated the release of LDH,and increased GSH content and SOD activity in cultured lens. Conclusion Abalone shell extract can alleviate the oxidative stress induced cataract formation,and this effect is mainly related to its improvement of the endogenous antioxidant system in lens.2012年福建省卫生厅中医药科研专项课题(No.WST201210);; 2013年福建省卫生厅中医药科研专项课题(No.wzhw201302);; 2014年厦门市科技局科技惠民项目课题(No.3502Z20144030

金电极表面植物原生质体的固定化

Barley protoplast was immobilized on poly(dially dimethylammonium) (PDADMAC) modified gold electrode via the electrostatic attraction between the positively charged amine groups of PDADMAC and the negatively charged barley protoplast. STM image reveals that PDADMAC/Au(111) surface displays a nano organized dot(4-6 nm) array structure. The processes of the PDADMAC adsorption and of the barley protoplast immobilization were monitored from the in situ QCM frequency change. The effects of the adsorbed mass and of the density and viscosity of medium on the frequency change of QCM were discussed, respectively. The QCM result shows that the thickness of the adsorbed PDADMAC layer is 2.4 nm

An Era of Women's Poetry in China : Transformation and Development in the New Era

Chinese literature stepped into another prosperous era in the 1980s, when humanistic concerns became the main theme in Chinese society. In the works of contemporary woman poets of China, we can see that feminine consciousness has awakened, just like the case of Japan in postwar period. New women's is exemplified by the poetry of Shu Ting, whose romantic reflection upon life is clearly marked by an awakened female subjectivity. The poetry in the era can be divided into three categories represented by three poets. The first category represented by Yi Lei, whose poetry tries to dismantle herself and deconstructs traditional understanding of woman. Zhai Yongming is the major poet of the third category, whose extraordinary insights disclose the most inner experience of women. These three categories can be read as three stages of transformation which correspond to Elaine Showalter's three steps of development in feminist consciousness. Although women's movements have never taken place in China and Japan in the same manner as it did in America, there are many similar aspects in the way how women come to reflect their gender awareness

The Awakening of Women in Literature : The First Stage of the Development of Women's Literature in China and Japan

The emergence of a number of prominent women writers at the beginning of the 20th century in China and Japan suggests that women are no longer passive objects in literature, Indeed, women now constitute active subjects in this field. In this paper, I would like to examine the sources of similarities between women's literature in China and that of Japan. First, both Japan and China had the long history of feudalism, which became the basis of the suppression of expressing individuality in these countries. These cultural, economic and social transformations in China and Japan led people to realize the improtance of liberating themselves from feudalism and of creating a space for expressing their individuality. In this context, Chinese and Japanese literature discovered 'human as individual' which is the product of enlightenment thought brought about from the West. One of the most remarkable discovery about 'human as individual' was the discovery of 'women', which was accompanied by the call for women's liberation by pioneering female thinkers. Secondly, the forces of persistent traditional culture on one hand and emerging modernization on the other inculcated talented women in China and Japan with unique ideas and artistic inspiration for literature. Thirdly, those women who were engaged with literature during this period of time were regarded as 'mad women' in these societies. Their refusal to follow the traditional norms led them to be defined as daughters unworthy of their father's respect. Fourthly, woman's writing is the product of the author's experience. The seminal period of women's literature was characterized by the closer relations between authors and their works and by the mixture of spoken and written words. Finally, women writers became conscious of the importance of adopting original styles in their writing. It can be said that Japan saw the development of women's literature earlier compared with China because the influence of enlightenment thought came to Japan much earlier than other Asian countries. The relative distance between literature and politics in Japan might have left an open space for women's literary expression. Also, unlike Chinese women, Japanese women were free from the oppressive custom of footbinding. This may account for a lighter touch in Japanese women's writing compared with their Chinese counterparts who were coerced into this oppressive practice
