为探明中小企业安全管理员工作异化的原因及形成机理,进而提出针对性防范措施,深度访谈中小企业的25名安全管理员,采用“情境过程”框架,遵循扎根理论程序,建构了中小企业安全管理员工作异化形成机理模型,并分析了相关因素对中小企业安全管理员工作异化的影响。结果表明:当地应急管理部门、中小企业领导和员工在各自行为逻辑主导下,受内外部情境影响,分别选择形式化监管、模糊性问责,应付式管理、表面化支持,象征性参与和折扣性执行的行为策略。受这些行为策略的刺激,中小企业安全管理员产生自保、同情员工等心理,进而对应选择盲目追随、避责为先,一味顺从、不争权利,放宽要求、处罚宽松等行为策略,最终导致工作异化发生。

为了揭示社会人口统计学因素和情境因素之间复杂的交互关系如何促成员工低频安全违规行为,结合组态思想和个体-情境互动理论,采用模糊集定性比较分析(fsQCA)方法分析1294份员工调查数据,探究个体(雇佣形式和性别)和情境(同事安全违规频率、企业安全投入、企业员工规模和行业危险程度)因素构成的不同条件组态对员工低频安全违规行为的影响。研究发现:任何单一因素均不构成员工低频安全违规行为的必要条件。员工低频安全违规行为存在3种不同驱动模式:非高危行业同事低频安全违规模式、高安全投入与同事低频安全违规共驱模式以及非高危行业大型企业高安全投入模式。同事低频安全违规行为在4种组态解中均是实现员工低频安全违规行为的核心条件。本研究引入fsQCA探究个体与情境因素对员工低频安全违规行为的组态效应,不仅拓展了对员工低频安全违规行为驱动模式的理解,还有助于倡导组态方法在行为安全领域的应用。

Previous studies on the relationship between polar motion and water mass change have mainly concentrated on the excitation of polar motion via global terrestrial water storage changes(TWSC). In view of the uneven distribution of global terrestrial water storage, the relationship between regional water mass change and polar motion needs to be further explored owing to the lack of documented results. In addition, given the uncertainty in the estimation of TWSC, it is required to develop appropriate indices to describe water mass change from different perspectives. The Amazon River basin(referred to Amazon hereafter), containing the world's largest river, located at around the 90°W longitude, is selected as the study area. Water vapor flux, precipitation, runoff and TWSC are selected as the indices of water mass changes to reveal the relationship between polar motion and water mass change in this giant basin. The Mann-Kendall(M-K) method, the accumulated anomaly analysis method and the curvature method are used to identify the abrupt change points; the least squares method is used to estimate the trends,and the Fast Fourier Transform(FFT) and the Ensemble Empirical Mode Decomposition(EEMD) are used to perform a periodic analysis, for all the above indices. It is shown that, of all the indices from 1948 to 2011, water vapor flux is the most closely related index to polar motion. In detail, precipitation and water vapor flux contain beat periods of polar motion; water vapor flux,precipitation and polar motion have a common M-K test abrupt change point(occurring in ca. 1968) at the 0.05 significance level; water vapor flux has a similar accumulated anomaly curve with that of polar motion; and water vapor flux is more highly correlated with polar motion than most other indexes. It is found, just like global TWSC, the χ2 component of the excitation via water vapor flux and water storage change in the Amazon follows that of observed polar motion; χ1 does not follow. However,
