An Empirical Study on the Impact Effects of Negative Reports on Product——Case of the Jiugui Liquor Plasticizer Storm

以酒鬼酒公司2012年11月19日的塑化剂报道为例,利用ff3f模型检验了产品负面报道对行业及业内的关键对手、最大对手和最小对手的冲击效应。结果发现,产品负面报道仅对关键对手有显著但有限的负面冲击,且小规模和低负债率的关键对手受到的负面冲击更显著更持久。由此获得的启示是:产品差异化及积极响应危机有助于化解产品负面报道的冲击。Choosing the reports on Jiugui Liquor plasticizer storm as a case which published on November 19,2012,the pa per analyzes impact effect of negative reports on product to industry,key competitors,the strongest competitors and the weak est competitors by using FF3F model.The results show that the negative reports on product only bring about significant but limited adverse impact effects to key competitors,and the negative impact effects suffered by key competitors with small scale and lower debt ratio will be more outstanding and last longer.The enlightenment obtained is that product differentia tion and positive response to crisis can help to defuse impact effects of negative reports on product.中国博士后基金项目“产品负面报道的金融加速器效应研究——以不信任情绪蔓延和资产负债表传染为中介变量”(2011M500884); 教育部人文社会科学规划项目“产品负面报道的资产负债表传染的防治研究:ERM-IF下CSR导向内部控制框架构建”(12YJAZH106); 国家自然科学基金项目“跨企业边界的成本协同管理与价值创造驱动因素研究”(70872096); 南京审计学院项目“高管层财务决策的走向、贸易信贷及资本结构的链式调整:基于前景理论的分析”(NSK2009/B13); 江苏省2010年‘

An Empirical Study on the Financial Accelerator Effect of Negative Reports on Product——Case of Spillover Effect of Sanlu Milk Powder Public Scandal

使用12家乳制品类上市公司2005-2012年的季度动态面板数据,文章对“三鹿毒奶粉事件“这一产品负面报道的“小冲击,大波动“的金融加速器效应进行了检验,结果发现,在研究的样本范围内,存在金融加速器效应;但金融加速器效应的两个不对称特征与理论本身所揭示的相反,即受冲击时期的资产负债表状况对投资支出影响显著但敏感性弱于其他时期;大公司的资产负债表效应更显著且受冲击时这种效应也很显著。这可能源于产品负面报道的溢出效应不仅带来了传染,也带来了竞争,在危机时期,大公司更倾向于采用竞争策略,夺占问题企业的市场份额。Using quarter dynamic panel data of 12 listed-companies of dairy industry from 2005 to 2012,the paper empiri cally analyzes the small shocks and large fluctuations of the financial accelerator effect of negative reports on product of Sanlu Milk Powder Scandal Event and finds that the financial accelerator is existence but its two asymmetric features are contrary to theoretical expectations.In other words,the influence of balance sheet to investment is significant during the crisis and the sen sitivity is weaker than other periods; Large company's balance sheet effects are more significant and the sensitivity of big com pany's investment to balance sheet is more significant during the crisis,which may result from the spillover effects of product negative reports not to bring contagion effects but effects of competition and in order to seize market share during the crisis,big companies are more likely to adopt competitive strategy.国家自然科学基金项目“跨企业边界的成本协同管理与价值创造驱动因素研究”(70872096); 中国博士后基金项目“产品负面报道的金融加速器效应研究——以不信任情绪蔓延和资产负债表传染为中介变量”(2011M500884); 教育部人文社会科学规划项目“产品负面报道的资产负债表传染的防治研究:ERM-IF下CSR导向内部控制框架构建”(12YJAZH106); 南京审计学院项目“高管层财务决策的走向、贸易信贷及资本结构的链式调整:基于前景理论的分析”(NSK2009/B13); 江苏省2010年“

等离子体增强热氧化法制备氧化锌纳米棒及其反应机制

提出一种等离子体热氧化法,即通过自制的等离子体增强水平管式炉沉积系统,将金属锌箔在氧气与氩气混合气体中放电生成氧化锌纳米棒,并考察了反应温度、氩气与氧气的流量比以及放电电流对生成的氧化锌的形貌和微观结构的影响.结果发现:在反应温度为500℃、氩气与氧气流量比(体积比)为9∶1时,有比较均匀、稳定的氧化锌纳米棒的生成;并且随着电流值不断增大,氧化锌纳米棒变长.此外,还提出了在等离子体条件下合成氧化锌纳米棒的生长机制:金属锌在适当的温度条件下加热,形成锌蒸汽并在锌箔表面凝结成金属颗粒;然后在O2-Ar气氛中,在等离子体放电过程中O2能有效地电离为O+、O2+离子,并在氩气辅助下进一步被等离子体转化为活化的氧原子并与锌反应形成氧化锌核,再向富氧的区域延伸,形成氧化锌纳米棒.深圳市基础研究项目(JCYJ20170306141238532

表面电性可控磁珠微流控芯片在DNA提取中的应用

制备了表面电性可控的氨基化SiO2@Fe3O4磁性复合微球,采用激光刻蚀和热压键合的方法制作了聚甲基丙烯酸甲酯（PMMA）材质的DNA固相萃取芯片,将磁珠灌注于芯片通道中,借助永磁铁固定并控制磁珠,将磁珠芯片应用于人类全血中的基因组DNA提取,优化了提取实验条件,并对提取产物进行凝胶电泳和PCR分析。实验结果表明,磁珠微流控芯片成功地从全血中提取出纯度较高的基因组DNA,提取效率约35%,提取液的凝胶电泳条带与商品化试剂盒提取的基因组DNA一致,提取液可用于进一步的PCR反应。国家星火计划项目(No.2015GA721002);;黄土与第四纪地质国家重点实验室开放基金(No.SKLLQG1607);;福建省中青年教师科技计划项目(No.JAT170817)资助~

强制医保制度下无保险人群的健康状况研究

因为就业单位不缴或欠缴医疗保险费而被迫无法纳入医疗保险体系的城镇职工在本文中被称为“医保夹心层”。据估算，我国目前存在上千万的医保夹心层人群。本文利用国务院关于城镇居民基本医疗保险试点评估调查2007－2009年的跟踪调查微观数据，研究了医保夹心层的健康及其医疗服务利用情况。我们发现，在控制了个人特征、就业状况、保险状态以及家庭经济状况后，医保夹心层职工的健康状况较差；其无保险状态会直接影响医疗服务利用，表现为医保夹心层更少接受住院服务（但在门诊服务方面没有差别），但一旦住院，夹心层住院花费及其负担都会更重；其次，医疗保险状态还会影响健康意识，表现为夹心层人群在了解医疗保健知识、定期身体健康检查方面缺乏积极性。本文发表在《经济研究》2013年第7期，118-131

堵塞对复合垂直流湿地水力特征的影响

　复合垂直流人工湿地系统(IVCW)堵塞后其水力特征会发生变化,通过示踪剂对小试和中试系统堵塞前后的水力特征进行了研究。结果表明,堵塞后IVCW出水流量减小,小试系统实际停留时间由堵塞前21.3h延长至32.5h,中试系统实际停留时间从19.4h延长至26.8h。IVCW堵塞后容易造成下行池表面积水,既恶化了卫生条件又降低了系统的处理能力

[[alternative]]Appreciation test research —The example of the 2003 Taipei County junior high school art class entrance exam.

[[abstract]]This research aims to study of the items of the 2003 Taipei County junior high school art class entrance exam. A series of analyses were done on the test items, the testing data ,and the interview data from the teachers and the subject students. The purpose was to analyze those data, gather some relevant opinions and reactions to serve as the basis for future test-item design. Some important conclusions were reached as follows: I.Item design and the educational concepts of art: We took into account the testing purposes, the choosing of the test types, and the variety of the test items. However, the validity planning and the test-item screening were not consistent with the standardized testing procedures. This paper used the rational of aesthetic education and curriculum standard as bases. The purpose of the paper mainly focused on the aesthetic perception and the art knowledge, The proportion of art knowledge items was higher because of the evaluation of students’ ability in thinking/cognition, and the importance of cultural issues. II.The analysis of test items: On the whole, the difficulty of the test items were of medium-low and the item discrimination index is medium. Most of the test items were consistent with the standard of item analysis. The test items were co-designed with illustrations. All these were in line with the content of aesthetic education. This test had already included the comprehensive version of curriculum standards. It had good content validity; however, the content validity would have been even better if we could have focus on material and subject matter of aesthetic perception. As for the internal consistency reliability coefficient, it was not high. On the overall score distribution, the scores of scores of all students was slightly higher than the norm. III.Responses: Most of the interviewed teachers believed that aesthetic perception was the most suitable testing content while art knowledge was not so much recommended. Nine teachers were against using multiple true-false items while five teachers considered the number of testing items too few. Although the difficult testing items of this paper were only few; however, most of the more difficult testing items have made a great impact on both teachers and students’ feelings. Lastly, the researcher made some suggestions to some future testing applications of the appreciation and some relevant research.
