供应链不确定性、组织学习与供应链绩效的关系研究

首先阐述了供应链管理研究中组织学习与供应链绩效的相关研究成果,探讨了供应不确定性和利用型学习的关系、技术不确定性和探索型学习的关系、利用型学习和探索型学习与供应链绩效的关系,并提出相关假设,接着采用调查问卷的方法搜集样本与数据,使用李克特五点量表对供应链绩效的题项进行测量,运用结构方程模型检验相关假设,并得出供应不确定性正向显著影响利用型学习,技术不确定性正向显著影响探索型学习,利用型学习和探索型学习正向显著影响供应链绩效。最后给出了研究结论的理论意义、对企业管理的启示、研究的局限性及进一步的研究方向。     

投桃何以报李:企业内外部社会责任对管家行为的影响机制研究

当员工感知到企业的善行,即企业善待员工或是积极履行对外部利益相关者的责任,是否会激发员工"舍己为公"的行为倾向,使其为了保护组织长远利益而牺牲个人短期利益呢?本研究依据社会交换和社会认同理论,通过524份有效样本进行实证分析,探讨员工感知的企业社会责任对"舍己为公"的管家行为的作用机制。结果表明,员工感知的内部和外部企业社会责任均正向影响员工的管家行为。责任知觉和道德认同分别在员工感知的内部企业社会责任与管家行为、员工感知的外部企业社会责任与管家行为间起中介作用,且责任知觉和道德认同的中介作用没有显著差异。     

我国城镇已婚妇女照料父母与自评健康的关系研究

我国老年人以非正式照料为主,妇女承担了主要的照料责任。政府减少对非正式老年照料的支持以及老年人口的快速增长将会加重家庭中女性的照料负担。利用1997、2000、2004和2006年中国营养与健康调查(CHNS)数据和Ordered Probit模型来研究城镇已婚妇女照料父母及其自评健康的关系。在我国城镇,与不照料父母相比,照料父母的已婚妇女更倾向于报告较差的健康水平,并且"自评健康状况非常好"的概率减小,而"自评健康状况一般"的概率增大。应该关注日益繁重的照料责任,以及工作与家庭照料之间的激烈竞争可能给妇女的心理、身体和社会福利带来的负面影响。     

Inter-market competition for exchange traded funds

We examine how the different mix of informed and liquidity trading in the market for ETFs affects the nature of inter-market competition. We find that both the characteristics of the securities and the structures of the competing markets jointly determine the nature of inter-market competition. Given the superior execution quality on the ECNs and the low adverse selection costs in the ETF market, anonymous market such as the ECNs, attract both liquidity and informed traders. We also find that markets compete in a subset of ETFs. In addition, we find that quotebased competition is prevalent in the market for ETFs.     

Drivers of firm formalization in Vietnam: an attention theory explanation

Informal enterprises are widely viewed as a mechanism to engage unemployed people in the economy and thereby alleviate poverty in developing economies. However, over-representation in an economy may lead to both economic growth and broader employment opportunities being sacrificed. This paper presents a process model to investigate three potential drivers for firms to formalize: the first from a desire to grow and develop the firm through innovation, the second from the wish to access government financial support and the third stimulated by the payment of unofficial payments or bribes. We use data from surveys of Vietnamese firms in 2005, 2007, 2009 and 2011 to investigate these drivers of formalization. Although we find support for all three of these drivers, the results differ in significance across years and firm types. We explain these differences using attention theory to show how different situations and events can make the formalization decision more likely over time.     

基于V-系统的时间序列跳跃点检测新算法

一些时间序列中跳跃点往往包含比较重要的信息,对其进行检测和定位对实证分析有着非常重要的意义。本文基于一种完备正交函数系、多小波-V系统,构造了离散正交V变换,提出检测跳跃点的一种新算法DOVT-JDA(Discrete Orthogonal V Translation-Jump Point Detection Algorithm),并针对存在市场微观结构噪音和跳跃的时间序列做了数值模拟。模拟结果表明本文提出的检测跳的新算法DOVT-JDA不仅行之有效,而且计算简单。     

CBE模式及其在焊接专业教学改革中的应用探索

在基于"能力本位"教育的CBE模式启发下,结合焊接专业自身特点,从教学内容、教学方法和教学模式等方面入手就该专业的教学改革作了些许分析和阐述,皆在培养出具有较强的实践能力和一定的科研能力且能够较快较好适应社会适应岗位的中高级焊接技术人才。在教学内容上,力求做到"必需"和"够用",并及时更新补充焊接领域的新知识,加强实践教学环节并将科研和教学有机结合,以培养学生的创新能力和创新意识。在教学方法上,重视学生个体性意识,突出学生主体性意识,转被动接受为主动探求,充分发挥学生学习的主观能动性。在教学模式上,以就业为导向,以职业岗位所需能力为出发点和核心,改革单一教学模式,建立校内校外实训基地,引入国际焊接工程师资格培训认证,有效提高学生的就业适应能力。     

When new product development fails in China: mediating effects of voice behaviour and learning from failure

This paper investigates conflicts following a new product development (NPD) failure. Conducted in a Chinese business setting, the study examines whether voice behaviour and learning from failure mediate the relationship between task- and emotional conflict emerging from NPD failure. Our findings indicate that voice behaviour and learning from failure are necessary to effectively reduce task and emotional conflict and thus to enhance future NPD. Specifically, it is revealed that emotional conflict leads to a reduced level; and that voice behaviour and learning from failure are significant mediators that influences the relationships between emotional and task conflicts with it.     

Export intensity of foreign subsidiaries of multinational enterprises: The role of trade finance availability

We examine the relationship between the role of trade finance availability and the export intensity of foreign subsidiaries of multinational enterprises (MNEs). In developing our hypotheses, we draw upon insights derived from “new” internalisation theory (international business literature) and international trade finance (international economics literature). We empirically test these hypotheses using survey data compiled from subsidiary managers in six ASEAN countries, supplemented with host-country level data. We conceptualise, empirically test, and establish that the subsidiary-level capability in combining and utilising internal and external debts is an important subsidiary-specific advantage to support export intensity. We find that subsidiaries employ intra-firm loans from MNE internal capital markets and, to some extent, bank loans from external financial institutions to boost their export intensity. Subsidiaries may have concerns about foreign exchange risks, but the use of appropriate foreign exchange risk management is positively associated with export intensity. We discuss the implications of our findings for theory and practice.
