The influence of perceived Human Resource strength on safety performance among high-speed railway drivers: The role of organizational identification and psychological capital

Introduction: Under the Chinese railway system reform background, high-speed railway drivers face continuous organizational change. As a communication channel between organizations and employees, the implementation of Human Resource Management (HRM) requires urgent attention. The present study explored the impacts of perceived Human Resource (HR) strength on safety outcomes premised on social identity theory. The relationships among perceived HR strength, organizational identification, psychological capital, and safety performance were investigated. Method: This study gathered 470 sets of paired data from Chinese high-speed railway drivers and their direct supervisors. Results: The results indicated that perceived HR strength positively affects safety performance via organizational identification, directly and indirectly. The findings also revealed that psychological capital promotes the direct effect of perceived HR strength on drivers’ safety performance. Practical Applications: Railway organizations were suggested to not only focus on the HR content but also consider the HR process, especially in an organizational change context.

“I’m energized to” & “I’m able to”: A dual-path model of the influence of workplace spirituality on high-speed railway drivers’ safety performance

Workplace safety has always been at the core of the sustainable development of high-speed railways in China, where drivers are a significant factor in railway systems in terms of ensuring safe operation. As a spiritual resource perceived by individuals in the workplace, workplace spirituality can improve the safety performance of individuals by internally stimulating their self-efficacy and passion for work. Under the influence of workplace spirituality, drivers are not only likely to be more “energized to” take part in safety work, but also more “able to”. Based on the model of proactive motivation and conservation of resources theory, a dual-path model was constructed in the present study to explore the influence of workplace spirituality on the safety performance of high-speed railway drivers as well as the mediating effects of self-efficacy and passion for work. Through the analysis of the data from high-speed drivers in 10 railway bureaus of China (N = 325), workplace spirituality was found to be positively related to safety performance. At the same time, the dual-path model was supported, that is, the mediating effects of self-efficacy and passion or work were successfully confirmed, respectively. The present study provides new insights into the management and cultivation of high-speed railway drivers as well as the safety development of organizations both theoretically and practically.

Association between obese phenotypes and risk of carotid artery plaque among chinese male railway drivers

BackgroundChina has the world’s highest rail transportation network density, and the prevalence of obesity among railway workers in China is more than twice that of adults in the world. Carotid artery plaque (CAP) is a simple and noninvasive predictor of early atherosclerosis, while the association between different obese phenotypes and CAP risk among Chinese male railway drivers is unclear.MethodsThis cross-sectional study was performed among 8,645 Chinese male railway drivers. Obese phenotypes were assessed based on the obesity status (the body mass index ≥ 28 kg/m2 as obesity vs. < 28 kg/m2 as non-obesity) and metabolic status (metabolically healthy vs. metabolically unhealthy). Metabolically unhealthy was defined as the presence of at least one dysfunction, including elevated blood pressure, elevated fasting blood glucose, elevated triglyceride, and reduced high-density-lipoprotein cholesterol. Four obese phenotypes were defined based on the body mass index and metabolic status, i.e., metabolically healthy non-obesity (MHNO), metabolically healthy obesity (MHO), metabolically unhealthy obesity (MUO), and metabolically unhealthy non-obesity (MUNO). Multivariable logistic regression was employed to estimate the association between different obese phenotypes and the risk of CAP. Subgroup analysis was performed to examine the variation of the association by age, circadian rhythm disorders, and history of smoking and drinking.ResultsThe prevalence of CAP among male railway drivers in MHO, MUO, MUNO, and MHNO was 8.75%, 18.67%, 17.82%, and 5.36%, respectively. Compared to those with MHNO, an increased risk for CAP was observed among those with MHO (OR = 2.18, 95% CI: 0.82, 5.10), MUO (OR = 1.78, 95% CI:1.44, 2.21), and MUNO (OR = 2.20, 95% CI: 1.67, 2.89). The subgroup analysis showed that both of the metabolically unhealthy groups (MUNO and MUO) aged < 45 years were prone to a higher risk of CAP (for the MUNO group, OR = 4.27, 95% CI:2.71, 7.10; for the MUO group, OR = 4.00, 95%CI: 2.26, 7.17).ConclusionThe obese phenotypes are associated with CAP risk in male railway drivers, especially those with metabolically unhealthy conditions aged < 45 years.

Prevalence of obstructive sleep apnea in a sample of Egyptian railway drivers

Background There are scanty international and even no Egyptian studies addressing the prevalence of obstructive sleep apnea syndrome (OSAS) in railway drivers with an expected high risk of accidents. Thus, it is worth studying and assessing the prevalence and predictors of OSAS among Egyptian railway drivers. Patients and methods This prospective cross-sectional screening study was conducted on 160 Egyptian railway drivers. They were subjected to medical history taking and examination, anthropometric measurements, oxygen saturation (SpO2) by oximetry, arterial blood gases, Friedman obstructive sleep apnea–hypopnea syndrome score measurement, and Arabic version of both Berlin and STOP BANG questionnaires. Then, limited night polysomnography (PSG) was performed in high-risk patients. Finally, full channel PSG was done for positive limited night PSG. Results The prevalence of sleep apnea among the studied cases was 4.22%. There was high statistically significant difference between the non-OSAS group and the OSAS group regarding age less than or equal to 49 years [odds ratio (OR)=11.364], witnessed apneas during sleep (OR=175), weight in kg more than 95 (OR=13.00), PaO2 less than or equal to 88 (OR=31.0), PaCO2 more than 39 (OR=31.0), and average SPO2 less than or equal to 88 (OR=34.0). Regarding parameters of limited night PSG, the apnea–hypopnea index cutoff point was more than or equal to 5 with an area under the curve (AUC) of 100%, O2 desaturation index cutoff point was more than 17.2 with an AUC of 100%; lastly, the average SPO2 cutoff point was less than or equal to 88% with an AUC of 76.4%. Conclusion This study highlights for the first time that the prevalence of OSAS was 4.2% in a sample of Egyptian railway drivers. Our results further point out that weight, neck circumference, systolic blood pressure, PaO2, and PaCO2 are the most useful predictors of suspecting OSAS. Also, parameters of limited PSG are considered a useful tool in confirming suspected patients with OSAS.

The study was carried out on a sample of 108 qualified railway drivers using a professional simulator that allows to simulate three degrees of freedom in activity. On the basis of empirical data it is shown that the degree of freedom in activity is manifested in individual productivity. The structures of professional talent, different in composition and degree of integration, are formed depending on the objective degree of freedom in activity.

Authentic leadership, person-organization fit and collectivistic orientation: a moderated-mediated model of workplace safety

PurposeWorkplace safety has been a persistent issue for safety-critical organizations. Based on self-verification theory, this study investigates how authentic leadership affects safety behaviors in a collectivistic context.Design/methodology/approachThis research collected 259 matching questionnaires for high-speed railway (HSR) drivers and their supervisors in China. Specifically, HSR drivers were invited to fill in their general perceived authentic leadership, person-organization fit and collectivistic orientation. In addition, their direct supervisors were invited to assess their safety behaviors.FindingsAuthentic leadership exhibits a significant positive impact on safety compliance and safety participation, implying that authentic leadership positively impacts safety behavior. The person-organization fit partially mediated the relationship between authentic leadership and safety behavior (safety compliance and participation). Furthermore, collectivistic orientation moderates the relationship between authentic leadership and person-organization fit.Originality/valueThe findings of this study provide important insights into authentic leadership and person-organization fit for developing effective strategies to improve workplace safety.

How work-family conflict predict HSR drivers safety performance? Empirical evidence from China

PurposeDrawing on ego depletion theory, this study aims to provide insights into the effect of work-family conflict on the high-speed railway (HSR) drivers’ safety performance by examining the mediating role of ego depletion and the moderating roles of work-family centrality and supervisor safety support.Design/methodology/approachIn total, 243 HSR drivers from 7 railway bureaus in China were surveyed. Structural equation modeling was used to test the hypotheses.FindingsBoth work-to-family conflict and family-to-work conflict have direct and positive effects on HSR drivers’ ego depletion and indirect effects on both safety compliance and safety participation via ego depletion. Moreover, both the direct effect of work-family conflict on ego depletion and its indirect effect on safety performance are moderated by work-family centrality. Supervisor safety support plays a buffering role in the relationship between ego depletion and safety performance.Originality/valueThis study examined the relationship between work-family conflict and safety performance based on the perspective of ego depletion theory. The findings testify to the importance of reducing work-family conflict among HSR drivers pursuant to maximizing safety.

Paternalistic Leadership and Safety Participation of High-Speed Railway Drivers in China: The Mediating Role of Leader-Member Exchange.

This research aimed to examine the effects of paternalistic leadership on the safety participation of high-speed railway drivers. Survey data were collected from 601 drivers in major Chinese rail companies. Structural equation modeling was conducted to analyze the influence of paternalistic leadership on safety participation via leader–member exchange (LMX). The results indicated that moral leadership directly promotes safety participation. Besides, benevolent leadership was positively associated with safety participation. Also, LMX partially mediates the positive relationship between benevolent leadership, moral leadership, and safety participation. Therefore, paternalistic leadership promotes the safety participation of high-speed railway drivers.

Risk factors for cardiovascular disease among railway locomotive drivers

Cardiovascular diseases in locomotive drivers are a factor limiting their working activity, as they can potentially increase the risks of accidents and disasters in rail transport. Working conditions of drivers are associated with occupational hazards that have a negative impact on the cardiovascular system. A review of clinical studies examining the risk factors for cardiovascular disease indicates the significant role of psychological stress on the health status of drivers. It was revealed that the negative effects of stress on the cardiovascular system depend on work stress, work schedule, and also on social factors: job satisfaction, salary, quality of rest and sleep. The studies revealed a correlation between the development of cardiac rhythm disturbances of high gradations with psychoemotional stress and sleep apnea in locomotive drivers.

Vitamin D deficiency study in railway drivers.

Heart rhythm disturbances are significant pathology and one of the reason of sudden cardiac arrest. Locomotive crew drivers are at high risk for cardiovascular diseases, including heart rhythm disturbances. Multiple factors as a professional stress, frequent night shifts, lack of insolation, diet disbalance, low physical activity, exposure to vibration and noise, and an unfavorable industrial climate. In this study it was found that railway-men are predisposed to vitamin D deficiency. This condition reduces resistance to stress and increases risk of unfavorable heart rhythm disturbances.

The article is devoted to the poorly studied problem of the formation of talent in the conditions of different degrees of freedom in activity and the impact on that formation of a person’s conservative and innovative semantic attitudes towards the introduction of new equipment. The main objective of the study is to describe how the conditions of different degrees of freedom in the activity are refracted with internal conditions, which are conservative and innovative semantic attitudes and various talent structures. The study was conducted on a sample of 54 qualified railway drivers using a specialized simulator which allows to simulate three degrees of freedom in the activity. The psychological analysis of the activity revealed seven abilities ensuring the implementation of the activity. Based on empirical data, the article shows that low, medium and high degrees of freedom in activity are manifested in different degrees of productivity. Conservative and innovative semantic attitudes to the introduction of new equipment do not have a significant effect on the productivity of the activity in the conditions of different degrees of freedom. Along with this, depending on the conservative and innovative semantic attitudes, different structures of talent in terms of composition and degree of integration under the conditions of different degrees of freedom in the activity are formed. On the one hand, conservative and innovative semantic attitudes act as internal determinants; on the other hand, low, medium and high degrees of freedom in the activity act as external determinants of the formation of various talent structures.

SPONTANEOUS AND PURPOSEFUL DEVELOPMENT OF ABILITIES AND SUCCESS IN NON-STANDARD ACTIVITY CONDITIONS

This article is devoted to the problem of professional abilities from the position of structural-functional approach. The following questions are considered: how professional abilities provide the productivity of activity; how the development of professional skills is carried out; what is the dependence of the specific structure of abilities and spontaneous and purposeful development in non-standard activity conditions. The study was conducted on a sample of 36 qualified railway drivers using a specialized simulator. The psychological analysis of the activity revealed seven abilities ensuring the implementation of the activity. Based on empirical data, it is shown that groups with spontaneous and purposeful development of abilities have statistically significant differences in the productivity of activity that were carried out in non-standard conditions and requirements. And these differences are in favor of the group with spontaneous development of abilities. It was proved that various structures of abilities are formed depending on their spontaneous and purposeful development, and that these structures of abilities provide the development of a new way of action by the subject in individual measure of integration.
