Dose safety motivation mediate the effect of psychological contract of safety on flight attendants' safety performance outcomes?: A social exchange perspective

This study proposes and tests a conceptual model that investigates the mediating effect of safety motivation linking psychological contract of safety (PCS) as manifested by employer obligations of safety and employee obligations of safety to safety violations and safety creative performance (SCP). Data were collected from a sample of flight attendants with two weeks time lag in Iran. Underpinned by social exchange theory, the results of structural equation modeling revealed that safety motivation fully mediates the simultaneous effects of PCS indicators on safety violations and SCP. Specifically, indicators of PCS jointly enhance safety motivation. In turn, safety motivation reduces safety violations, while enhancing SCP. Theoretical and practical implications evoked from the results advance existing knowledge of organizationally social interactions in promoting safety and the motivational mechanism through which PCS predicts employees' safety performance outcomes.     

探析横管式煤气初冷器阻力大的原因及应对措施

在焦化行业内,炼焦过程必将产生大量焦炉荒煤气,采用煤气鼓风对焦炉荒煤气进行处理就成为工作重点,不仅能够促进环境的改善,还可以回收荒煤气中大量的化工原材料,并带来较大的经济效益。但在焦化厂实际生产中,横管式煤气初冷器常常因阻力过高发生故障,对煤气鼓风机的正常运作形成干扰,造成装置沉积物阻塞与环境污染等问题。论文以湖北中平鄂钢联合焦化有限责任公司的横管式煤气初冷器为实例,简要分析阻力增大的原因及应对措施。     

Fluctuating levels of personal role engagement within the working day: A multilevel study

In this diary study, we examined a theoretical model in which the psychological conditions of meaningfulness, availability, and safety serve as mechanisms through which the work context during discrete situations within the workday influences “state” engagement. We further theorised that a person's “trait” level of engagement would exert cross‐level effects on the state level relationships. Multilevel analyses based on a sample of 124 individuals in six organisations and 1,446 situational observations revealed that meaningfulness and availability (but not safety) mediated the relationships between perceptions of the work context and state engagement. High levels of trait engagement strengthened the within‐person relation between availability and state engagement, yet weakened the within‐person relation between meaningfulness and state engagement, suggesting two different processes may be at play. Overall, the findings advance our understanding of engagement as a multilevel and temporally dynamic psychological phenomenon and promote a contextually based HRM approach to facilitating engagement.

新冠肺炎疫情对中小微外贸企业的影响及对策

突如其来的新冠肺炎对全球经济造成了很大的影响,我国对外贸易当然更是无法幸免。但总体而言,笔者认为,短期影响虽然十分严重,但正在逐步消弭;中期影响需要认真对待,损失基本可控;长期影响更加深刻,但是依然可以化解——我国以及我省对外经济贸易总体向好的态势有望保持。然而,面广量大的中小微外贸企业原本就身体单薄,这场突如其来的疫情,无疑又是雪上加霜,日子更加艰难,亟待关注与帮扶。     

阐述如何加强道路桥梁施工监理

通常,道路桥梁的施工难度较高,其中涵盖的内容较多,如技术管理、预算管理、成本控制等。这些因素使道路桥梁的施工变得更为困难,施工的复杂性和综合性更加突出。在桥梁的施工过程中,存在着许多风险,所以需要做好施工监理工作,从而最大限度地保障施工过程中不会出现任何故障和问题。因此,加强道路桥梁施工监理至关重要。论文从道路桥梁施工的角度,探究和分析如何做好相关的监理工作。     

关于我国瓦斯治理现状及存在问题的分析

随着我国煤矿开采深度的不断加大,煤层的透气性逐渐降低,而瓦斯的压力、浓度、放散量和速度则不断升高,因此加大瓦斯治理力度尤为关键。本文我们将针对当前我国煤矿瓦斯治理的现状,针对当前工作中存在的问题,提出煤矿瓦斯治理工作方面的意见和措施,以期能够提高煤矿的安全性,减少煤矿瓦斯事故的发生。     

中小企业全面预算管理存在的问题与对策

在经济全球化的背景下,大部分企业都面临着巨大的竞争压力,尤其对于中小企业来说,在复杂环境下保持稳定发展更是一种挑战。构建全面预算管理体系是企业提升市场竞争力的重要手段,虽然预算管理流程通常只分为预算编制、预算执行控制、预算考核三大环节,但我国中小企业的全面预算管理还存在诸多问题。论文据此进行分析并提出解决对策。     

凿井水下底卸式自动卸料吊桶

吊桶是立井井筒开凿时期提升矸石和运送材料及升降人员的主要容器,吊桶的卸矸目前多采用挂钩式或座钩式卸料方式;但是随着矿井的开凿深度不断延伸,在过透水层时,由于探放水不及时或涌出水比较大,超出了井筒的排水量,或者是由于冷冻井在解冻后,井筒的井筒质量不过关,各别井壁也会发生透水事故;这就会出现淹井事故,有时淹井深度达二三百米。对于处理这种淹井事故,往往只有一个办法,那就是用沙或混凝土对井筒回填;这就需要吊桶在下到几百米下的水底自动把料卸掉,但现在矿井常用的挂钩式吊桶和座钩式吊桶已经不能满足这个需要了。
