双边匹配理论及其在金融市场应用的研究综述

20世纪60年代，学者们开始研究双边匹配问题，匹配算法及其应用研究不断推进，研究的样本与研究结论日益全面。国内关于双边匹配的研究起步较晚，不仅相关的理论研究相对滞后，而且应用研究范同相对较窄，尤其是在金融市场的应用研究更显薄弱。本文将对双边匹配理论的发展与应用进行梳理，并对该理论在金融市场的应用问题进行研究。     

Test of a multidimensional model linking applicant work experience and recruiters' inferences about applicant competencies

Previous research have shown that applicants' work-experience information influences recruiters' hiring recommendations. This study extends previous research by proposing and testing the relationship between applicants' work-experience dimensions (i.e. job tenure, job breadth, leadership experience and challenging job experience) and recruiters' perceptions of applicants' job competencies (i.e. professional knowledge, interpersonal skills, general mental ability and trait conscientiousness). Results from a policy-capturing experiment partially support our hypotheses and show that recruiters use different aspects of applicant work experience to infer different dimensions of applicant job competencies.     

膨胀剂在混凝土施工中的应用

为了提高混凝土的抗渗性能,以及减免由于混凝土收缩而产生的裂缝,在混凝土中经常加入膨胀剂。混凝土膨胀剂的功能是使硬化后的混凝土产生一定的体积膨胀,抵销混凝土硬化早期产生的体积收缩。

科学管理中的统计应用

科学管理离不开统计与调查,因为,管理过程就是计划、组织、指挥、协调和控制的过程。所有这些过程都离不开决策。从这个意义上说,管理就是决策。科学决策是科学管理的核心。一般地说,科学决策程序包括目标、信息、设计、评估、选择、执行和反馈等阶段。在这些阶段中,都离不开信息的搜集和处理,都离不开调查和研究。因此决策过程和管理过程,实质上就是反复调查研究的过程。调查与统计是科学决策和科学管理的客观基础,离开了科学的调查与统计就没有科学决策和科学管理。在这里所说的统计的含义实际上就是信息流收集和控制,因此从某种意义上说,统计是科学管理的基础,离开了统计信息的传递、分析,科学管理无从谈起。     

Effectiveness of mobile application for menstrual management of working women in Japan: randomized controlled trial and medical economic evaluation

Abstract

Aims: Hormonal imbalances can affect a woman’s physical and mental condition, impacting her daily life and productivity. A mobile application, “Karada-no-kimochi”, predicts the menstrual cycle based on recorded data, and provides the information regarding menstruation. This study investigates the effectiveness of the application from health condition and labor productivity loss perspectives, and evaluates its cost-effectiveness for employed women in Japan.

Materials and methods: A randomized controlled trial (RCT) was performed to compare the use of the application and non-intervention in female workers (20–45 years) based on an online survey. A discrete-event model based on the RCT data, published literature, and claims data was used for the cost-effectiveness analysis.

Results: The intervention and non-intervention groups comprised 612 and 914 women, respectively. In the intervention group, the incidences of depression (0.16%) and dysmenorrhea (0.33%) were significantly lower than those of the non-intervention group (0.77% and 1.31%, respectively) in the third month. While labor productivity and absenteeism varied, presenteeism showed almost no change across groups. The quality-adjusted life year in the intervention group was 6.84 (0.07 higher than that in the non-intervention group). By analyzing medical expenses and making assumptions regarding productivity, we estimated that the aggregate of medical expenses, productivity loss, and application fee for the intervention group could be lower than that of the non-intervention group by over JPY 130,000 (USD 1,170, as of December 2017) per individual.

Limitations: The subjects included were willing or relatively willing to use the application. Because all outcomes were based on online surveys, the results depended on the objectivity and preciseness of the reports provided by users, and those with severe symptoms might not provide reports.

Conclusions: The results suggest that using the application is cost-effective and might reduce the incidence of dysmenorrhea and depression.
