新时期监事会的业务监督——以中日两国董事义务为视角

我国公司法上的监事会，是对董事及高级管理人员的业务执行进行专门性监督的常设机构，该专门性监督能否取得实效将直接影响公司的经营绩效及利害关系人的利益，而明确监事会的业务监督权限是提高监督实效的关键。本文通过与日本法的比较研究，以2005年公司法增设的勤勉义务（Duty of Care）为焦点，对公司法修改后的股份有限公司监事会的业务监督范围及内容进行了新的解读与探索.     

非负权最短路问题的一种简便算法

提出了非负权最短路问题的一种新算法。与有名的Ｄｉｊｋｓｔｒａ算法相比，这种算法计算简便、容易理解、易于编程。     

公开市场操作公告对中国股市交易行为的影响

基于MRR结构模型,利用广义矩估计方法,从信息不对称和流动性成本角度考察了央行公开市场操作公告对股票市场交易行为的影响。实证结果表明,公开市场操作披露前股票市场的信息不对称程度、流动性成本并未发生显著变化,公开市场操作披露后30分钟内,信息不对称程度增加,流动性成本下降。在考虑了公开市场操作未预期的利率变化具体内容后,所得结果并没有显著变化。     

顾客第一论

“顾客第一”有其特定的内涵,它充分体现社会主义企业的根本目的,因而是企业所有经营观念中的一个根本性观念,也是企业生产经营的一个根本指导思想。企业要实现其双重目的,促进物质文明和精神文明建设的发展,并树立各种现代经营观念,就必须坚持顾客第一。     

江苏省基层医务人员工作压力研究

对905名基层医务人员进行问卷调查,了解基层医务人员工作压力情况及其影响因素,为建立适合基层卫生机构的良性人才发展机制提供依据。基层医务人员整体工作压力得分为56.54分;单因素方差分析显示,不同性别、年龄、婚姻状况、学历、职称、机构类型、工作量、工作年数、受患者尊重程度和社会地位的医务人员工作压力得分差异具有统计学意义;多元线性回归分析结果显示,社会地位、工作量、工作年数、受患者尊重程度、最高学历和性别对基层医务人员工作压力的影响具有统计学意义。需要着重关注乡镇卫生院医生的工作压力情况,重点应放在提升基层医务人员社会地位、及时关注中坚力量等方面,从而减轻其工作压力,提高工作积极性。     

基于遗传粒子群算法的堆垛机作业路径优化

通过查慎行对《瀛奎律髓》中陆游诗歌的评点可以看出，他在章法、用典、字法、句法、对仗等方面对陆游诗歌多有称赏，对陆游学古不化及艺术上的瑕疵亦多有批评，总体上体现出较为客观的批评态度。在查慎行的诗学理论体系中，陆游的地位经历了一个由高到低的过程。查慎行对自己青年时期偶像的批评与颠覆，体现出其晚年诗学理论的转变与成熟。     

Staff rostering in call centers providing employee transportation

We address the staff rostering problem in call centers with the goal of balancing operational cost, agent satisfaction and customer service objectives. In metropolitan cities such as Istanbul and Mumbai, call centers provide the transportation of their staff so that shuttle costs constitute a significant part of the operational costs. We develop a mixed integer programming model that incorporates the shuttle requirements at the beginning and end of the shifts into the agent-shift assignment decisions, while considering the skill sets of the agents, and other constraints due to workforce regulations and agent preferences. We analyze model solutions for a banking call center under various management priorities to understand the interactions among the conflicting objectives. We show that considering transportation costs as well as agent preferences in agent-shift assignments provides significant benefits in terms of both cost savings and employee satisfaction.     

Data envelopment analysis in the presence of measurement error: case study from the National Database of Nursing Quality Indicators® (NDNQI®)

Data envelopment analysis (DEA) is the most commonly used approach for evaluating healthcare efficiency [B. Hollingsworth, The measurement of efficiency and productivity of health care delivery. Health Economics 17(10) (2008), pp. 1107–1128], but a long-standing concern is that DEA assumes that data are measured without error. This is quite unlikely, and DEA and other efficiency analysis techniques may yield biased efficiency estimates if it is not realized [B.J. Gajewski, R. Lee, M. Bott, U. Piamjariyakul, and R.L. Taunton, On estimating the distribution of data envelopment analysis efficiency scores: an application to nursing homes’ care planning process. Journal of Applied Statistics 36(9) (2009), pp. 933–944; J. Ruggiero, Data envelopment analysis with stochastic data. Journal of the Operational Research Society 55 (2004), pp. 1008–1012]. We propose to address measurement error systematically using a Bayesian method (Bayesian DEA). We will apply Bayesian DEA to data from the National Database of Nursing Quality Indicators^® to estimate nursing units’ efficiency. Several external reliability studies inform the posterior distribution of the measurement error on the DEA variables. We will discuss the case of generalizing the approach to situations where an external reliability study is not feasible.     

弗洛伦斯·南丁格尔与克里米亚战争

弗洛伦斯·南丁格尔被誉为克里米亚战争（1854-1856）的女英雄和现代护理学的主要奠基人。战地记者无情揭露了克里米亚战争中英国军队存在的诸多弊端，促使英国政府派遣南丁格尔护士团前往克里米亚战争前线医院，而南丁格尔在护理教育、军队医疗和卫生改革等方面的贡献都要追溯到她在克里米亚战争中的经历。     

Strategic Design Responsiveness: An Empirical Analysis of US Retail Store Networks

This study uses a service operations management (SOM) strategy lens to investigate chain store retailers' strategic design responsiveness (SDR)—a term that captures the degree to which retailers dynamically coordinate investments in human and structural capital with the complexity of their service and product offerings. Labor force and physical capital are respectively used as proxies for investments in human capital and structural capital, whereas gross margins are proxies for product/service offering complexity. Consequently, SDR broadly reflects three salient complementary choices of SOM design strategy. We test the effects of “brick and mortar” chain store retailers' SDR on current and future firm performance using publically available panel data collected from Compustat and the University of Michigan American Customer Satisfaction Index databases for the period 1996–2011. We find that retailers that fail to keep pace with investments in both structural and human capital exhibit short‐term financial benefits, but have worse ongoing operational performance. These findings corroborate the importance of managers strategically maintaining the complementarity of design‐related choices for improving and maintaining business performance.
