经典信度理论和概化理论的计量学透视

从计量学的角度分析了经典信度理论和概化理论的局限、错误和无力,并重点揭示了经典理论和概化理论几个方面的问题.经典理论由于采用了相关分析进路,既无力应对多不确定度源的测量情景,也无法较好地满足实践对条件不确定度的要求.概化理论虽然可以同时考虑多个不确定度源,但由于技术上采用了方差分析进路,即使使用得当,也不能够很好地解决条件不确定度问题.     

Advancing OSCM scientific knowledge by replicating empirical findings: Step-by-step procedure and illustration for transformative replication endeavors

Replication endeavors contribute to the accumulation of scientific evidence about previously reported findings and are crucial for scientific progress. Replication studies are, however, often discouraged and rarely published in the operations and supply chain management (OSCM) discipline. In this article, we offer a framework for replications consisting of two complementary tables. This framework recognizes two types of replications already defined in the literature (i.e., The Exact (EXT) Replication and the Methods-Only (MTD) Replication) and adds to these two new types (i.e., the Bounded-Conceptual-Extension (BCE) Replication and the Transformative (TRF) Replication). The framework clarifies what constitutes replications, forms of replication endeavors, and their purposes. Importantly, we also differentiate replication endeavors from reproducibility tests, robustness checks, and post hoc analyses. Moreover, we describe a seven-step procedure to guide the design, execution, and presentation of replication endeavors, illustrating these steps by conducting a TRF Replication that incorporates, at the same time, a BCE Replication and an MTD Replication of Polyviou et al. (2018). The proposed framework and seven-step procedure hopefully motivate OSCM scholars to embrace replications as valuable scientific endeavors that can yield corroborating evidence to bolster confidence in previously reported findings and, better yet, provide new nuanced findings to advance precise scientific understanding of past and new OSCM phenomena.     

乡村中学教师体质健康满意度量表的编制--基于贵州乡村教师的调查

为有效评估乡村中学教师的体质健康现状,在开放性访谈和专家评估的基础上,初步编制了“乡村中学教师体质健康满意度量表”,继而以贵州乡村中学教师为研究对象,分别进行题项分析、探索性因素分析和验证性因素分析,最终形成正式量表。研究结果显示,乡村中学教师的体质健康满意度量表由生理满意和运动满意两个因子构成。信效度分析表明,所编制的量表符合心理测量学的要求,因此,该量表是一个适合评估乡村中学教师体质健康满意度的有效工具。     

Reliability analysis of man–machine systems using fuzzy cognitive mapping with genetic tuning

This article offers a method for analyzing the reliability of a man–machine system (MMS) and ranking of influencing factors based on a fuzzy cognitive map (FCM). The ranking of influencing factors is analogous to the ranking of system elements the probabilistic theory of reliability. To approximate the dependence of “influencing factors—reliability,” the relationship of variable increments is used, which ensures the sensitivity of the reliability level to variations in the levels of influencing factors. The novelty of the method lies in the fact that the expert values of the weights of the FCM graph edges (arcs) are adjusted based on the results of observations using a genetic algorithm. The algorithm's chromosomes are generated from the intervals of acceptable values of edge weights, and the selection criterion is the sum of squares of deviations of the reliability simulation results from observations. The method is illustrated by the example of a multifactor analysis of the reliability of the “driver–car–road” system. It is shown that the FCM adjustment reduces the discrepancy between the reliability forecast and observations almost in half. Possible applications of the method can be complex systems with vaguely defined structures whose reliability depends very much on interrelated factors measured expertly.
