基于宏观线收缩率的复合材料固化变形仿真预测

纤维增强树脂基复合材料在固化过程中受材料体系(如树脂类型与体积含量、纤维类型等)和固化制度(如固化设备、固化压力、固化升降温速率、固化模具类型等)的影响,会在宏观层面产生固化变形,影响复合材料制件的形面精度。提出基于宏观线收缩率的固化变形仿真预测方法,在材料体系和固化制度一定的条件下,对各理化变量进行常数化处理,归结为X、Y、Z三个方向长度变化量与固化前长度的比值。建立有限元仿真模型,预测对称铺层和非对称铺层C型试验件的固化变形结果,与实际扫描结果进行对比。结果表明：仿真预测结果最大相对误差为10.68%,平均相对误差为3.59%,预测精度能够满足工程实践的需要,极大降低了固化变形预测难度,能够对模具补偿形面设计、制件固化变形控制等起到切实的指导作用。     

The differential effects of CEO narcissism and hubris on corporate social responsibility

Research Summary: While prior studies have predominantly shown that CEO narcissism and hubris exhibit similar effects on various strategic decisions and outcomes, this study aims to explore the mechanisms underlying how narcissistic versus hubristic CEOs affect their firms differently. Specifically, we investigate how peer influence moderates the CEO narcissism/hubris—corporate social responsibility (CSR). With a sample of S&P 1500 firms for 2003–2010, we find that the positive relationship between CEO narcissism and CSR is strengthened (weakened) when board‐interlocked peer firms invest less (more) intensively in CSR than a CEO's own firm; the negative relationship between CEO hubris and CSR is strengthened when peer firms are engaged in less CSR than a CEO's own firm. Managerial Summary: Some CEOs are more narcissistic while others may be more hubristic, but these two groups of CEOs hold different attitudes toward the extent to which their firms should engage in corporate social responsibility (CSR). Our findings with a large sample of U.S. publically listed firms suggest that narcissistic CEOs care more about CSR, but hubristic CEOs care less. Interestingly, when narcissistic CEOs observe their peer firms engaging in more or less CSR than their own firms, they tend to respond in an opposite manner; in contrast, hubristic CEOs will only engage in even less CSR when their peers also do not emphasize CSR. Our findings point to a fundamental difference between CEO narcissism and hubris in terms of how they affect firms' CSR decisions based on their social comparison with peer firms.     

The effects of strategic and market complementarity on acquisition performance: evidence from the U.S. commercial banking industry, 1989–2001

Most traditional research on mergers and acquisitions tends to focus on the role of similarity in explaining acquisition performance. While scholars have recently begun to examine acquisition complementarity, there is still little evidence concerning how complementarity influences acquisition performance. Further, previous research has not drawn the connections between related contexts and the potential benefits from complementarity. In this article, we move the study of acquisition complementarity forward by investigating the effects of strategic and market complementarity on acquisition performance in the context of related horizontal acquisitions. We also propose that two key attributes of acquirers—strategic focus and out‐of‐market acquisition experience—will moderate this relationship. We investigate our research questions in the context of all 2,204 acquisitions made by publicly traded U.S. commercial banks during the 12‐year period from 1989 to 2001. Our findings are generally supportive, suggesting complementarity is an important antecedent of acquisition performance, and raising important issues on the nature of acquisition research in general.

当前宏观经济形势与2004年的比较与思考

当前,国内外经济形势错综复杂。文章通过对近期和2004年中国宏观经济形势的比较,分析其中的异同,以厘清未来走势,并为宏观调控提供借鉴。两个时期部有一些相同点：中国经济从低谷走出,乐观情绪升温,房价骤涨,通胀开始抬头,中国跟随世界进人新一轮加息周期,人民币升值压力不断加大。两者不同点是：当前货币增长速度远远快于2004年。贸易顺差更大,信贷和财政状况逊色。未来,预计CPI回升势头更快,央行面临回收流动性的压力更大,贸易摩擦加剧,中美息差可能进一步扩大,人民币的升值压力将加大。     

资产注入、证券市场监管与绩效

证券市场监管的效率一直是学术界和实务界所关注的问题。由于上市公司的资产注入可划分为经证监会核准的监管型资产注入以及仅通过公司董事会和股东大会批准就可实施的自愿型资产注入,从而为研究证券市场监管效率问题提供了新的契机。本文以2002-2006年五年间上市公司与其控股股东发生的重大资产注入为样本,实证检验了证券市场监管对资产注入绩效的影响。我们的研究发现监管型资产注入对上市公司的绩效产生了正面的影响,而自愿型资产注入对上市公司绩效的影响则并不显著,证券市场监管发挥了相应的效用。     

关于开放市场条件下防范系统性风险的研究

随着经济金融全球化程度的加深,评价和防范开放经济条件下一国系统性金融风险的重要性日益明显。文章根据系统性金融风险的表现形式,提出了一个三层次的风险评价指标体系,并通过熵值法确定各子系统风险因子之间的权重。实证分析结果显示,近年来我国金融业总体稳健程度得到有效提升,但未来仍需密切关注风险因素的动态变化,采取切实有效的措施夯实系统性金融风险管理体系建设。     

我国金融物流发展模式研究

随着我国经济社会的迅速发展,第三方物流企业发展传统物流业务遇到了很大的瓶颈,发展现代物流的呼声越来越高,在此背景下,金融物流应运而生。金融物流是一种创新理论,国内对金融物流的研究相对较少。因此,对我国金融物流发展模式的研究显得尤为重要。     

The impact of the global financial crisis on the cross-currency linkage of LIBOR–OIS spreads

This article examines the impact of global financial crisis on cross-currency linkage of the LIBOR–OIS spread, a financial stress measure in interbank markets. The impulse response analysis is conducted in a multivariate setting, adopting the bias-corrected bootstrap as a means of statistical inference. The overall evidence suggests that the crisis has substantially changed the nature of the cross-currency interactions in liquidity stress. Also global money markets have failed to contain stress in US dollar funding and the role of the Japanese yen as a liquidity source appears to be significant, while these two currencies drive the cross-currency system of liquidity stress.
