A comparison of adverse impact levels based on top‐down,multisource, and assessment center data: Promoting diversity and reducing legal challenges

We compared levels of adverse impact (AI) against minorities and women based on three promotional decision methods for 428 associate store managers of a Fortune 500 retailer: top‐down appraisal (TDA), multisource appraisal (MSA), and an assessment center (AC). We found significant effects for race and minority status (favoring whites) but no significant effects for gender across all three methods. Comparisons were analyzed using two definitions of AI (four‐fifths rule and the Fisher Exact Test) with a selection ratio (SR) of .25. No evidence of AI was found against blacks for any of the methods. For Hispanics, AI was found under the four‐fifths rule for the AC. For women, the four‐fifths rule was violated using TDA. Results provide some partial support for the argument that diversity goals are more likely to be met using assessment centers compared to TDA when the preponderance of raters are white men. Our data also suggest that carefully crafted, job‐related, top‐down appraisal, combined with rater training, may be effective in facilitating the promotion of more women and minorities and reducing the probability of legal problems. © 2012 Wiley Periodicals, Inc.     

The customer consequences of returns in online retailing: An empirical analysis

Pressure continues to build on the operations management function to facilitate system and firm level benefits. In the online marketplace, one area of growing interest is that of product returns. Though commonly viewed as a cost center from an operations perspective, operations’ actions have the potential to strongly influence future customer buying behavior in several ways. Using an archival database of actual purchase and returns history provided by a moderately sized online retailer, this study examines the relationship between a customer's experience of product returns, and subsequent shopping behavior. Employing transaction cost, consumer risk, and procedural justice theories, we demonstrate that the returns management process, rather than being regarded as an afterthought to the production and deployment of goods, can significantly and positively influence repurchase behavior. Additionally, we provide evidence that certain customers should be considered for prioritization in the returns process. We suggest ways through which operations managers can take care in discharging their responsibilities in this area – to make returns processing more than simply a “necessary cost of doing business” rather, using it to their advantage in engendering repeat and increased purchase behavior.     

Process quality improvement: An examination of general vs. outcome-specific climate and practices in hospitals

Despite numerous efforts to foster quality improvement in healthcare, much of the extant data and research indicate that substantial shortcomings in the delivery of effective and reliable care remain. This research examines both general and outcome-specific operations management efforts and their impact on delivering quality healthcare. We empirically test a conceptual framework of safety culture that accounts for the use of general quality practices as well as outcome-specific approaches in light of the general and more focused climates in which those practices are embedded. We utilize structural equation modeling to analyze a unique pairing of primary data from a survey of quality improvement directors and chief nursing officers at 272 hospitals across the U.S. with secondary data on process of care performance publicly reported by the federal government's Center for Medicare and Medicaid Services (CMS). General safety climate and quality practices are found to establish an environment in which outcome-specific efforts enable process quality improvement. A split-group SEM analysis highlights significant differences in managing healthcare safety outcomes through climate and practices. In particular, the employment of practices focused on the specific outcome goals is found to relate to higher quality of patient care in smaller hospitals. In contrast, the development of a climate focused on specific outcome goals is found to relate to higher quality of patient care in larger hospitals. These findings suggest alternative approaches for small and large hospitals in the critical effort to improve patient safety and reduce healthcare costs.     

Service needs of elderly air passengers

The paper examines the perceptions of and satisfaction with air transportation services in a sample of persons aged 65 and over at Taiwan Taoyuan International Airport. This study finds that the performance of service attributes such as meals, information announcements, and on-board restrooms do not meet the respondents’ expectations. It also finds that the service needs of the younger and older elderly passengers differ.     

日本金融服务贸易自由化及其影响的实证分析

从日本经济的发展历程来看,金融服务贸易自由化对其化工产业及其电子信息行业的发展都起到了至关重要的作用。本文依据1985～2008年的日本相关数据,制度性量化指标量化金融服务贸易自由化程度以及估计金融服务贸易自由化程度对人力资本吸收程度、技术吸收程度以及日本经济增长的影响,结论发现金融服务贸易自由化程度越高,人力资本吸收速度越快,技术吸收速度增加对经济增长产生正效应。     

中国用工荒演变轨迹研究

文章对1979—2010年中国四大地区的劳动力就业数据,采用生物系统论研究方法,将地区劳动力视为复杂系统,对中国四大地区内外劳动力格局演变进行估计,从而深入讨论用工荒根源及演变轨迹。结果发现:劳动力就业自然增长率与人口自然增长率间有内在规律——23定律,这一定律是中国用工荒到来的根源,它决定中国东部、东北、中部、西部将先后于2014、2020、2025、2027年进入用工荒;东部用工荒是紧随劳动力自然就业繁荣期之后,而东北、中部和西部则是劳动力自然繁荣期后经历较长的潜伏期才进入用工荒。     

个体特征对农村劳动力进城就业途径选择的影响——基于对福州市部分企业的调查

以2009年暑期在福州市部分企业的调查数据为依据,运用logistic回归模型,对影响农村劳动力进城就业的因素进行了实证。分析结果表明,个人特征中的文化程度对农村劳动力进城就业选择老乡或亲友介绍这一途径具有显著的影响。文章对降低农村劳动力进城就业对老乡或亲友的依赖性,转而参加政府统一有序组织的进城就业,以提高在城市就业的稳定性及合法权益的保障性,提出了相应对策。
