Chinese version of the OSI: A validation study

This article examines the construct validity of the Occupational Stress Indicator (OSI) in its Chinese version as well as its criterion-oriented validity against self-reported data on absenteeism and accidents, using a final sample of 1054 workers in the Chinese manufacturing and power industries. The divergent and convergent validities of five of the OSI scales—Job satisfaction, Physical ill-health, Mental ill-health, Type A behaviour and Control—were examined by a multimethod-multitrait matrix technique. Results indicated that the Chinese OSI had fairly good validity in relation to other well-established measures as well as relevant organizational behaviours.     

驱逐“懈怠症”

保持高水平的生产力,或者更进一步,将生产力提升到更高的层面,这往往是高级经理人们最为关注的问题之一。但有些经理人的举措却证明是适得其反的,其结果生产力不升反降。举例而言,人们有一种自然倾向,尤其对那些经验缺乏的经理,就是认为仔细监督下级的工作会让他们的工作效率更高。但如果一味依靠监督     

The empirical analysis of the -bilateral optimized combinatorial auction model

This study proposes a new and highly efficient dynamic combinatorial auction mechanism—the N-bilateral optimized combinatorial auction (N-BOCA). N-BOCA is a flexible iterative combinatorial auction model that offers more optimized trading for multiple suppliers and purchasers in the supply chain than one-sided combinatorial auction. We design the N-BOCA model from the perspectives of market architecture, trading rules, and decision strategy for winner determination, the decision strategy for winner determination needs flexible optimization modeling capability. Thus rule-based reasoning was applied for reflecting the flexible decision strategies. We also show the viability of N-BOCA through Paired Samples T-test experimentation. It shows that N-BOCA yields higher purchase efficiency and effectiveness than the one-auctioneer to multi-bidders (1-to-N) combinatorial auction mechanism.     

Private Pensions — a Viable Alternative? Their Distributive Effects in a Comparative Perspective

Pension reforms have been on the political agenda of governments and international organizations like the OECD and the World Bank for some time. The strengthening of private elements in pension systems is often believed to intensify existing inequalities in the distribution of pensions among the population and to contribute to the marginalization of large groups of older people. This paper explores the distributive effects of private pensions on the basis of Luxembourg Income Study microdata for 12 industrialized welfare states. While confirming that private pensions indeed tend to produce specific inequalities, its results also emphasize the importance of policy factors in mitigating the distributive effects.     

Improving healthcare for children entering foster care

Despite the fact that children in foster care are, perhaps, the most vulnerable children, healthcare for them has been lacking woefully for many years. A growing body of research has documented the need for such care as well as the failure of child welfare agencies to make major improvements in providing healthcare to foster children. Nonetheless, current efforts are being made to change this situation. This article reports on one effort to improve the provision and timeliness of health exams for children entering care. One rural and one urban county served as project treatment sites, with two additional rural and urban counties serving as control sites. The treatment sites achieved a statistically significant improvement in their rate of exam completion as compared to the control sites. The study finds that despite an existing policy for healthcare for children entering foster care, legislation mandating additional efforts, shortened time frames, and provision for judicial oversight are needed for improvement.     

Did State Children’s Health Insurance Program Affect Married Women’s Labor Supply?

While the relationships between health insurance and the labor supply of women have been explored in the literature, little is known about the effects of offering public health insurance on the labor supply decisions of married women. This paper examines how the enactment of the State Children’s Health Insurance Program (SCHIP) affected the labor supply decisions of married women. Our empirical analysis showed that certain groups of married women reduced their number of hours worked upon SCHIP implementation. The results imply it is possible that some wives decreased their labor supply in order to make their children eligible for public health insurance.

Reinvigorating the social contract and strengthening social cohesion: Social protection responses to COVID-19

The COVID-19 pandemic has exposed the vulnerability of those who are inadequately covered by social protection in more and less developed countries alike, and has exacerbated the fragility of a social contract that was already under strain in many countries. A weak social contract in the context of an exceptional crisis poses a very real risk to social cohesion. Nevertheless, many States have reasserted themselves as the guarantor of rights by protecting public health and incomes. By sustaining these measures, economic recovery will be supported which will help minimize risks that may weaken social cohesion. However, this is a fast-moving, inherently unstable and protracted crisis. Social protection stands at a critical juncture. Decisive policy action will be required to strengthen social protection systems, including floors, as one of the cornerstones of a reinvigorated social contract.     

Preregistration in infant research—A primer

Preregistration, the act of specifying a research plan in advance, is becoming more common in scientific research. Infant researchers contend with unique problems that might make preregistration particularly challenging. Infants are a hard‐to‐reach population, usually yielding small sample sizes, they can only complete a limited number of trials, and they can be excluded based on hard‐to‐predict complications (e.g., parental interference, fussiness). In addition, as effects themselves potentially change with age and population, it is hard to calculate an a priori effect size. At the same time, these very factors make preregistration in infant studies a valuable tool. A priori examination of the planned study, including the hypotheses, sample size, and resulting statistical power, increases the credibility of single studies and adds value to the field. Preregistration might also improve explicit decision making to create better studies. We present an in‐depth discussion of the issues uniquely relevant to infant researchers, and ways to contend with them in preregistration and study planning. We provide recommendations to researchers interested in following current best practices.     

Noninformative priors for the between-group variance in the unbalanced one-way random effects model with heterogeneous error variances

For the unbalanced one-way random effects model with heterogeneous error variances, we propose the non-informative priors for the between-group variance and develop the first- and second-order matching priors. It turns out that the second-order matching priors do not exist and the reference prior and Jeffreys prior do not satisfy a first-order matching criterion. We also show that the first-order matching prior meets the frequentist target coverage probabilities much better than the Jeffreys prior and reference prior through simulation study, and the Bayesian credible intervals based on the matching prior and reference prior give shorter intervals than the existing confidence intervals by examples.
