Rejects reduction in a retail bank using Lean Six Sigma

Lean Six Sigma (LSS) is a majestic process improvement methodology that has been proved to be a powerful management strategy across services. The influential synergy of Six Sigma and Lean aims at improving the processes, focusing on both rapid and robust improvements, reducing waste and variation in the process. LSS generates successful results in key performance indicators (KPIs) based environments, where process data gets measured and leveraged for making essential management decisions. The aim of this paper is to highlight the importance of LSS in banking industry through a real-time process improvement study. The article establishes the literature for the need for LSS in banks detailing on customer facing metrics and process KPIs. An action-research study conducted in a retail bank is presented in LSS DMAIC methodology which reaped a benefit of INR 1.6 million and is a classic example of how LSS can bring bottom-line impact to an organisation, alongside contributing to the process improvement mind-set in employees.     

Evolution of Quality: First Fifty Issues of Production and Operations Management

Many contributions have been made to the field of quality since the inaugural issue of Production and Operations Management in 1992. The first issue called for more research and teaching on TQM, which resulted in two special issues dedicated to TQM. Many other articles related to quality have also been published in the first fifty issues of the journal on topics ranging from technical methods to the Baldrige Award and ISO 9000. As we review these articles, we assess their contribution and the progression of the field of quality. Although past research has advanced our understanding of quality, there still exists many research opportunities in developing more theory, using additional research methodologies, and studying emerging topics in this field.     

证券投资基金绩效评价方法与实证研究

传统的基金绩效评价方法具有诸多局限性,而DEA方法克服了传统评价方法因市场组合选择不同和无风险收益率确定不当而带来的评估结果失真的问题,从而提高了基金绩效评价的科学性和准确性。运用DEA方法对中国22支封闭式基金2000年至2002年间的相对投资绩效进行的实证分析,结果表明,在中国目前的证券市场环境下,多数基金的运作处于无效状态,基金绩效不存在明显的持续性和规模效应,不同投资风格的基金绩效也没有显著的差异。

X-效率与企业内部的个体激励

本文主要针对美国经济学家莱宾斯坦所提出的厂商内部的X-效率（X-efficiency）现象,以期望理论为框架,说明各种因素的变化是如何影响个体的努力程度,进而影响个体绩效和满意度,讨论并提出了提高厂商内部效率的某些实现条件和具体途径,以及理解中国国有企业低效率问题的若干分析思路。     

SC2053在川西化杀杂种小麦组合筛选中的应用初报

报道了我所利用SC2 0 53在杂种小麦研究中的应用情况。研究认为 :①多数小麦品种在剂量为 0 .6kg/hm2 ,雌雄蕊原基形成期至药隔期喷施 ,杀雄率能达 95%以上。药隔期为喷施临界期。品种、喷药剂量与喷药时期存在互作。②气候条件的改变对不同小麦品种生育进程的影响有差异。在杂交小麦制种中应对此加强研究 ,以利于花期调节。③在配制组合时 ,应特别注意抗性材料的选用。④超标优势明显的化杀杂种小麦 ,其优势主要表现在穗部性状上 ,尤其是穗粒数优势     

Teen Childbearing and Educational Attainment: A Comparison of Methods

This research examines the impact of teenage childbearing on secondary school completion, while focusing on the problem of causal ambiguity in the relationships among self-determined behaviours. Techniques for dealing with the teenage childbearing problem are discussed, and results from these methods are compared. Data from the High School and Beyond Study on young women (n = 5257) who were enrolled as sophomores in sample schools in February 1980 and who had not given birth before November 1980 are used. Results indicate that teen childbearing reduces the probability of completing high school by 8% to 10%. Some evidence suggests that programs that target reduction of teen childbearing in improving young women's education and subsequent economic and labor force outcomes.     

Understanding exponential smoothing via kernel regression

Exponential smoothing is the most common model-free means of forecasting a future realization of a time series. It requires the specification of a smoothing factor which is usually chosen from the data to minimize the average squared residual of previous one-step-ahead forecasts. In this paper we show that exponential smoothing can be put into a nonparametric regression framework and gain some interesting insights into its performance through this interpretation. We also use theoretical developments from the kernel regression field to derive, for the first time, asymptotic properties of exponential smoothing forecasters.     

变革型领导、交易型领导、信任和工作绩效的关系——以基层公务员为例

基于变革型领导理论、交易型领导理论和社会交换理论,探讨了中国背景下基层公务员变革型领导行为和交易型领导行为对工作绩效的差异及其影响机制,即变革型领导和交易型领导是否通过信任的中介作用对领导效能产生影响。通过对176名基层公务员的变革型领导、交易型领导、信任以及工作绩效之间的关系进行问卷调查,并采用层次回归分析的方法进行分析,研究结果如下：（1）变革型领导和交易型领导分别对工作绩效有显著的影响。（2）变革型领导没有比交易型领导表现出更好的预测作用。（3）信任在变革型领导和工作绩效之间起到部分中介作用,但在交易型领导和工作绩效之间没有起到中介作用。
