Psychosocial factors have received increasing attention regarding significantly influencing safety in the construction industry. This research attempts to comprehensively summarize psychosocial factors related to safety performance of construction workers. In the context of coronavirus disease 2019, some typical psychosocial factors are selected to further analyze their influence mechanism of safety performance.

First, a literature review process was conducted to identify and summarize relevant psychosocial factors. Then, considering the impact of the epidemic, hypotheses on the relationship between six selected psychosocial factors (i.e. work stress, role ambiguity, work–family conflict, autonomy, social support and interpersonal conflict) and safety performance were proposed, and a hypothetical model was developed based on job demands-resources theory. Finally, a meta-analysis was used to examine these hypotheses and the model.

The results showed these psychosocial factors indirectly influenced workers’ safety performance by impacting on their occupational psychology condition (i.e. burnout and engagement). Work stress, role ambiguity, work–family conflict and interpersonal conflict were negatively related to safety performance by promoting burnout and affecting engagement. Autonomy and social support were positively related to safety performance by improving work engagement and reducing burnout.

This research is the pioneer systematically describing the overall picture of psychosocial factors related to the safety performance of construction workers. Through deeply discussed the mechanism of psychosocial factors and safety performance, it could provide a reference for the theory and application of psychosocial factors in the field of construction safety management.

This paper aims at studying earnings management phenomenon in its wider social and economic context to get better understanding for the following points: whether there is “one-size-fits-all” earning management approach which can be widespread applied among nations and whether the Egyptian context affects managers’ trade-off between three different earnings management approaches: accounting, operational and investment.

The paper adopts interpretive approach and analyses data from official documents and 34 interviews with company executives; financial analysts; external auditors; and Stock Exchange regulators to inform our understanding of the influence of the Egyptian context on the trade-off between earnings management approaches.

The results show that there is no application for “one-size-fits-all” earning management approach; unlike the developed cultures, where R&D expenses and overproduction are extensively used for boosting profits, in Egyptian context they are not valid tools. The findings indicate that the Egyptian political and economic context remarkably affect managers trade-off earnings management approaches, leading executives to prefer operational manipulation compared with others.

This paper extends but adds to the literature by shedding light on the different implications of earning management theories based on the variation in the political, economic and operational contexts of firms; identifying that operational cash flows matter more to managers than accounting profits; focusing on the fact that managers differentiate and compare between three various earning management approaches: accounting techniques, investment activities and operational activities; and showing that changes in political and economic Egyptian context makes operational manipulation favorable to be adopted compared with others. It also overcomes the criticism of New Institutional Sociology Theory.

This study aims to determine how and through what mechanisms the outward foreign direct investment (OFDI) promotion effect of the Belt and Road initiative (BRI-OFDI) affects domestic investment. It is motivated by the context that China is fostering a new development pattern, as well as by the impetus from the Belt and Road initiative for the new pattern.

Drawing on data of Chinese-listed companies, this study uses a difference-in-difference method to explore the effect of the BRI-OFDI on domestic investment and a mediation model to illustrate the mechanisms.

The BRI-OFDI has a significantly positive effect on domestic investment, meaning that the Belt and Road initiative's OFDI promotion effect crowds in domestic investment. The results are heterogeneous: the crowding-in effect mainly exists in non-state-owned and technology-intensive enterprises, while a crowding-out effect is seen in state-owned and labor-intensive enterprises. The easing of corporate financing constraints and the expansion of market demand are two important mechanisms.

This study uses the Belt and Road initiative as an exogenous shock to investigate the impact of the initiative-induced OFDI promotion effect on domestic investment. It addresses the potential endogeneity issue confronting the studies on the relationship between OFDI and domestic investment in the literature. The authors focus on the possible spillover effects of the Belt and Road initiative discussing the impact of the BRI-OFDI on domestic investment from the micro-firm perspective. It offers a new perspective to objectively assess the initiative's policy effect.

The absence of robust information on the application of Human resources managemnet (HRM) practices in the Arab Middle Eastern region has generated an urgent need to understand what and how HRM practices can be used to manage employees in the region. Therefore, building on the social exchange theory and job demands-resources (JD-R) model, this paper proposes a model to examine the effects of high-performance work systems (HPWS) on employees' work-related outcomes, namely, job performance, organizational citizenship behavior (OCB) and innovative work behavior (IWB) in a non-industry setting in an Arab Middle Eastern context. In this model, work engagement was theorized to serve as an intervening mechanism among the aforementioned relationships.

Data were collected from 210 academic staff working in the Palestinian higher education sector, together with evaluations from 30 supervisors. Structural equation modeling (SEM) was employed to analyze the data.

The results indicate that HPWS positively affect employees' job performance, OCB and IWB. Moreover, work engagement partially mediates these relationships.

The results can be useful for managers in the Middle East pertaining to the role HPWS can play in boosting employees' job performance, OCB and IWB.

HRM research in Middle East, although limited, is mainly focused on examining the impact of HPWS on organizational rather than individual outcomes. In response to the scholarly call made on the strong need to conduct more HRM research in the Middle East (Budhwar et al., 2019), this research represents the first study that examines the impact of HPWS on in-role and extra-role performance in an Arab Middle Eastern context. Furthermore, the study contributes to the HRM research by relying on a sample from a non-industry sector rather than a sample from a manufacturing setting. Finally, this research is one of the few studies that explore the outcomes of HPWS in an academic setting through the intervening mechanism of work engagement.

Incivility is widespread in the workplace and has been shown to have significant affective and behavioral consequences. However, the authors still have a limited understanding as to whether, how and when discrete incivility events impact team performance. Adopting a resource depletion perspective and focusing on the cognitive implications of such events, the authors introduce a multi-level model linking the adverse effects of such events on team members’ working memory – the “workbench” of the cognitive system where most planning, analyses, and management of goals occur – to team effectiveness. The model which the authors develop proposes that that uncivil interpersonal behavior in general, and rudeness – a central manifestation of incivility – in particular, may place a significant drain on individuals’ working memory capacity, affecting team effectiveness via its effects on individual performance and coordination-related team emergent states and action-phase processes. In the context of this model, the authors offer an overarching framework for making sense of disparate findings regarding how, why and when incivility affects performance outcomes at multiple levels. More specifically, the authors use this framework to: (a) suggest how individual-level cognitive impairment and weakened coordinative team processes may mediate these incivility-based effects, and (b) explain how event, context, and individual difference factors moderators may attenuate or exacerbate these cognition-mediated effects.

The purpose of this paper is to investigate the influence of social capital and relationship quality on key account management (KAM) effectiveness.

Based on the literature, the authors designed a framework that links social capital, relationship quality and KAM effectiveness. Data were collected through a self-administered questionnaire. Using data from a sample of 172 business-to-business supplier firms, the authors examined this model.

The research results provide empirical support to the importance of relational aspects of KAM by showing how the relational aspects of relationship quality and social capital influence the effectiveness of the supplier-key account relationship.

The authors add to the literature on relational KAM by integrating theoretical perspectives on social capital, relationship quality and KAM. They develop a model that investigates the antecedents of the effectiveness of supplier–key account relationships from a relational perspective. The study explains the relationships between six constructs representing social capital (ability, benevolence, integrity, flexibility, information exchange and solidarity) and three constructs representing relationship quality (trust, satisfaction and relationship atmosphere), together with the relationships between these three constructs of relationship quality and KAM effectiveness.

The aim of this paper is to evaluate the impact of total quality management (TQM) practices on role stressors in Iranian manufacturing SMEs in order to determine the relationship between the multidimensionality of TQM practices and role ambiguity, role conflict and role overload.

Questionnaires are administrated to 410 employees of 100 different manufacturing SMEs in Iran.

The results support important negative association among some of TQM practices (such as employee involvement, information analysis, process management, supplier management, strategic planning and customer focus) and role conflict, role ambiguity, role overload. By utilizing multiple regression analysis, information analysis, supplier management, employee involvement, process management, customer focus, strategic planning are found to have significant and negative relationship with role stressors. Leadership and human resource focus are found to have significant and positive relationship with role stressors.

This model is perfect for practical usage by SME managers to estimate the perceptions of role stressors of employees in TQM oriented firms. The findings recommend that manufacturing should look into ways of improving the major roles of TQM practices in order to decrease the negative role stressors of employees.

TQM practices emerge to be related to role stressors (role ambiguity, role conflict and role overload), attending to an obvious noticeable gap in the previous studies of TQM and the psychological welfare of employees.

In this paper, with the goal of reducing the fuel consumption of UAV, the engine performance optimization is studied and on the basis of aircraft/engine integrated control, the minimum fuel consumption optimization method of engine given thrust is proposed. In the case of keeping the given thrust of the engine unchanged, the main fuel flow of the engine without being connected to the afterburner is optimally controlled so as to minimize the fuel consumption.

In this study, the reference model real-time optimization control method is adopted. The engine reference model uses a nonlinear real-time mathematical model of a certain engine component method. The quasi-Newton method is adopted in the optimization algorithm. According to the optimization variable nozzle area, the turbine drop-pressure ratio corresponding to the optimized nozzle area is calculated, which is superimposed with the difference of the drop-pressure ratio of the conventional control plan and output to the conventional nozzle controller of the engine. The nozzle area is controlled by the conventional nozzle controller.

The engine real-time minimum fuel consumption optimization control method studied in this study can significantly reduce the engine fuel consumption rate under a given thrust. At the work point, this is a low-altitude large Mach work point, which is relatively close to the edge of the flight envelope. Before turning on the optimization controller, the fuel consumption is 0.8124 kg/s. After turning on the optimization controller, you can see that the fuel supply has decreased by about 4%. At this time, the speed of the high-pressure rotor is about 94% and the temperature after the turbine can remain stable all the time.

The optimal control method of minimum fuel consumption for the given thrust of UAV is proposed in this paper and the optimal control is carried out for the nozzle area of the engine. At the same time, a method is proposed to indirectly control the nozzle area by changing the turbine pressure ratio. The relevant UAV and its power plant designers and developers may consider the results of this study to reach a feasible solution to reduce the fuel consumption of UAV.

Fuel consumption optimization can save fuel consumption during aircraft cruising, increase the economy of commercial aircraft and improve the combat radius of military aircraft. With the increasingly wide application of UAVs in military and civilian fields, the demand for energy-saving and emission reduction will promote the UAV industry to improve the awareness of environmental protection and reduce the cost of UAV use and operation.

In the limited existing research on smartphone addiction, reinforcement reward and automatic habit have been identified as two distinct underlying mechanisms. The purpose of this paper is to better understand the interaction between these two mechanisms, as well as role of smartphone features in activating different formation mechanisms.

An online survey with 379 samples was conducted to empirically validate the model. The data were analyzed by structural equation modeling approach.

The automatic habit strengthens the driving effects of reinforcement rewards (i.e. perceived enjoyment and mood regulation) on smartphone addiction. Smartphone features activate distinct underlying mechanisms. Value-added function facilitates the perception of reinforcement rewards, while convenience promotes the habit formation.

This study is one of the first ones that assess the interplay between the two formation mechanisms in the extant literature on smartphone addiction. This study also reveals the dangers of smartphone features which have always been regarded as advantages. The findings contribute to the current understandings of smartphone addiction.

This chapter examines the influence of outsourcing on airlines’ performance from countries of the Asia Pacific region. Performance in the context of this study is drawn from productivity growth and technical efficiency scores that are calculated using the standard data envelopment analysis (DEA) approach. We utilize data from airlines over the period 2003–2011 and estimate the impact of outsourcing on productivity and technical efficiency using generalized method of moments (GMM) estimators. The findings from DEA reveal an improvement in the technical efficiency score of airlines from Asia Pacific. Nonetheless, productivity estimates indicate fluctuations in the productivity growth trend of airlines, attributable to global economic recession in 2007/2008. GMM estimation results, however, suggest negative impacts of outsourcing on technical efficiency and productivity of the airlines from Asia Pacific countries. We offer several explanations for these outsourcing findings. Heavy outsourcing of airlines activities particularly maintenance of aircraft may negatively affect aircraft utilization and ultimately erode the service level of airlines. The erosion of the service level of airlines would affect the demand for air travel in a downward manner, thereby lowering the technical efficiency and productivity of airlines. Also, relatively low labor costs enjoyed by airlines in the Asia Pacific region would suggest that having many airline activities in-house would save operating expenses attributable to labor costs.
