Operational Risk in Financial Services: A Review and New Research Opportunities

We present a framework to describe and analyze operational risk in financial services from an operations management perspective, focusing in particular on process design, process management, and human behavior aspects. The financial services industry differs from other service industries in ways that affect the nature of the operational risks it is subject to. In recent decades, many books and papers have focused on operational risk in financial services; however, this literature has focused mainly on the conceptual and statistical aspects of operational risk management and not on its operational aspects. Operational risk in financial services has not received much attention from the operations management community. The framework presented here is based on the premise that operational risk in financial services can reap significant benefits from research done in the theory and practice of operations management in manufacturing industries as well as in other services industries. The objective of this study is to propose particular challenges and questions raised in the practice of operational risk management that may stimulate future research in this particular area of operations management.     

An upper bound on the minimal total cost of the transportation problem with varying demands and supplies

In general cases, to find the exact upper bound on the minimal total cost of the transportation problem with varying demands and supplies is an NP-hard problem. In literature, there are only two approaches with several shortcomings to solve the problem. In this paper, the problem is formulated as a bi-level programming model, and proven to be solvable in a polynomial time if the sum of the lower bounds for all the supplies is no less than the sum of the upper bounds for all the demands; and a heuristic algorithm named TPVDS-A based on genetic algorithm is developed as an efficient and robust solution method of the model. Computational experiments on benchmark and new randomly generated instances show that the TPVDS-A algorithm outperforms the two existing approaches.     

论经济增长的驱动因素:劳动生产效率与产业结构——以江苏省为例

本文利用LMDI指数分解方法建立了人均增长率测算模型。该模型可以分析产业GDP结构、产业劳动力结构、产业全员劳动生产效率以及劳动力占总人口比重等因素对人均GDP增长率的影响。江苏省人均GDP增长率的实证分析,表明产业全员劳动生产率和产业结构是该省2010年实现人均GDP增长率200%的主要影响因素。     

中国旅游上市公司全要素生产率研究

旅游上市公司是旅游业发展的微观主体,其全要素生产率全面反映了该行业的实际经营效率和发展趋势。本文基于Malmquist指数探讨了20家中国旅游上市公司2004-2009年的全要素生产率。Malmquist指数及其分解结果显示:中国旅游上市公司Malmquist指数年均增长率为-0.4%,其中纯技术效率的增长显著,年均增幅为1.3%;时间跨度层面,中国旅游上市公司的全要素生产率的年度波动性较大。此外,样本中旅游上市公司Malmquist指数与营业收入增长率未能兼顾;2008-2009年度粗放型增长的特征显著。     

黑龙江省"十五"期间招商引资总体情况与效益分析

通过统计资料,本文从总量结构、增长速度、内外资结构和地区结构四个方面对"十五"期间黑龙江省的招商引资工作进行了总体的情况和效益分析。在总量结构分析中,发现贸易总额增长但项目数量却变化不大;从增长速度看,各项指标都呈稳步上升态势,显示黑龙江省的招商引资工作处在高速增长阶段;从内资和外资结构看,内资在增长和比重上都优于外资;在对地区结构的分析中,发现总体上处于稳定增长态势,地区间则不均衡。最后,结合分析结论,进一步简要阐述了其政策意义。     

河南省上市公司资本结构与绩效研究

以河南省上市公司为样本,用资产负债率和负债与股东权益比作为财务杠杆的代表变量,净资产收益率和总资产收益率作为公司绩效的代表变量,分析研究公司资本结构与资产结构、成长性、公司规模、获利能力和风险之间的相关性,以及公司绩效与资本结构之间的相关关系。研究结果显示公司资产结构和获利能力对资本结构有显著的影响,资本结构对公司绩效无显著影响。     

生态价值:基于马克思劳动价值论的一个引申分析

检视和比较中西方关于生态价值问题的研究文献,基于马克思劳动价值论,并将其引申扩展到探索生态价值的致思路径是:沿着人类社会生产力发展水平不断提升的线索,从经济系统、生态系统和生态经济系统考察商品总价值、生态总价值和商品价值总量之间的内在关联及其数量变化关系。随着人类社会生产力水平由低到高的提升,商品总价值、生态总价值和商品价值总量三者之间呈现由同向递增变动到无序变动、再到更高层次的同向递增变动的趋势。在中国当前经济社会发展面临严峻生态问题的状况下,重新认识和理解生态价值问题,将有利于改变当前衡量经济社会发展指标过度单一的局面,有利于转变人们对自然生态资源、生态环境的不合理开发和利用的传统发展理念,有利于有效推动自然资源定价和参与市场化治理,并为其提供理论基础,从而使自然生态环境能够被科学、合理、协调、可持续地开发和利用。     

Bisphenol A: How the Most Relevant Exposure Sources Contribute to Total Consumer Exposure

Bisphenol A (BPA) is an endocrine disrupting chemical that is found in human urine throughout industrial societies around the globe. Consumer exposure pathways to BPA include packaged food, household dust, air, and dental fillings. To date, information on the relative contribution of the different pathways to total consumer exposure is lacking, but is key for managing substance‐associated risks. We investigated the relative contributions of the pathways known to be most relevant for nine different consumer groups. Our results suggest that the most important pathways for infants and children are the use of polycarbonate (PC) baby bottles and for adults and teenagers the consumption of canned food. Dental surgery can also considerably contribute over a short time directly after the surgery. For infants fed with PC baby bottles with mean dose rates of 0.8 μg/kg_bw/d the highest exposure dose rate was calculated. This dose rate is far below the tolerable daily intake of 50 μg/kg_bw/d. However, it is of the same order of magnitude as recently reported concentrations that caused low‐dose health effects in rodents. We find a pattern of falling exposure levels with rising age that is supported by urinary concentrations of BPA available for selected consumer groups. Similarly, the exposure levels we predict are confirmed by the levels reported in these studies.     

充分世界化与民族复兴——试论胡适的中西文化冲突解决方案

面对近代中国尖锐复杂的文化冲突，胡适提出了充分世界化的方案，试图克服各种变相的“中体西用”论及其中蕴藏的虚骄自大心理。这是一个被视为“全盘西化”论、强调自我反省和自强开放的中国现代文化建设方案。尽管其中的缺陷十分突出，但对推进中国的民族复兴大业仍有一定的参考价值。     

跨国并购与我国企业技术进步的相关性分析

近年来，跨国并购逐渐成为我国企业国际化发展以及构建核心竞争能力的重要途径，而跨国并购能否对我国企业的技术进步起到积极的作用则成为理论研究的热点问题。针对此，采用全要素指标体系，分析了1991~2007年全要素增长率与跨国并购增长率之间的关系，认为:跨国并购的变化对技术进步具有一定的影响关系，但是由于技术并购在对外投资中的比重偏低，过分重视了技术的引进，忽视了技术的吸收消化过程等因素的影响，因此这种影响的效果并不显著。
