This paper aims to investigate the influence of religiosity on the relationship between abusive supervision and deviant work behavior (DWB). This paper examines whether the desire for revenge mediates the relationship between abusive supervision and DWB and whether the strength of this relationship is moderated by religiosity.

The proposed relationships were examined by collecting primary data from 350 employees using multistage sampling procedures. Hayes’ Process Macro was used to analyze the proposed moderated-mediation model of abusive supervision, DWB, religiosity and desire for revenge.

The analytical findings indicate that an employee’s desire for revenge mediates the relationship between abusive supervision and DWB. However, religiosity moderates the indirect effect of abusive supervision (mediated by the desire for revenge) on DWB.

To the best of the authors’ knowledge, this is the first study that explores the role of individual-level religiosity in mitigating the harmful effects of abusive supervision on deviant behavior and revenge in the workplace.

This research is aimed to mainly be applicable to expediting engineering projects, uses the method of inverse optimization and the double-layer nested genetic algorithm combined with nonlinear programming algorithm, study how to schedule the number of labor in each process at the minimum cost to achieve an extremely short construction period goal.

The method of inverse optimization is mainly used in this study. In the first phase, establish a positive optimization model, according to the existing labor constraints, aiming at the shortest construction period. In the second phase, under the condition that the expected shortest construction period is known, on the basis of the positive optimization model, the inverse optimization method is used to establish the inverse optimization model aiming at the minimum change of the number of workers, and finally the optimal labor allocation scheme that meets the conditions is obtained. Finally, use algorithm to solve and prove with a case.

The case study shows that this method can effectively achieve the extremely short duration goal of the engineering project at the minimum cost, and provide the basis for the decision-making of the engineering project.

The contribution of this paper to the existing knowledge is to carry out a preliminary study on the relatively blank field of the current engineering project with a very short construction period, and provide a path for the vast number of engineering projects with strict requirements on the construction period to achieve a very short construction period, and apply the inverse optimization method to the engineering field. Furthermore, a double-nested genetic algorithm and nonlinear programming algorithm are designed. It can effectively solve various optimization problems.

The Chinese government hopes to achieve the goal of benefiting citizens by building a National Integrated Online Government Service Platform (NIOGSP). However, citizens' low adoption of the platform makes it difficult for the government to achieve its goal. Research on the influencing factors of citizen adoption of NIOGSP can help the government fully understand the concerns and needs of its citizens and take targeted measures to increase citizen adoption.

First, this research builds a model of the citizen adoption process, including attention, retention and motivation, based on an observational learning model. Next, research variables are determined based on social cognitive theory, literature review and real-world needs. Finally, based on the questionnaire survey and structural equation model, the influencing factors of each stage of the citizen adoption process model are studied and the relationship between the three stages of the model is verified.

Results show that perceived usefulness (PU) and self-efficacy (SE) positively affect attention. SE positively affects retention, while perceived privacy (PP) negatively affects retention. PU, social influence, PP and anxiety positively affect motivation.

The conclusion of this study can provide reference for governments in various countries to establish and improve online one-stop government. In addition, this study verifies the citizen adoption process model and finds that there is no obvious causal relationship between attention and retention, but both have positive effects on motivation.

Although work-related antecedents of abusive supervision are well-known, knowledge on the cross-domain antecedents of this destructive leadership behavior is scarce. Accordingly, this study aims to investigate off-the-job supervisors’ after-work experiences that may influence their work behavior. The authors explore how and when a supervisor’s poor recovery experiences lead to abusive supervisory behaviors through a negative start-of-workday mood for high vs low supervisor sleep quality.

The authors conducted a single-source, three-phase field study (N = 422) to test the proposed moderated mediation model for participants from a large telecommunications company located in Anhui province, People’s Republic of China.

Poor recovery experiences in the supervisor’s personal life can spill over to their work domain and provoke abusive supervisory behavior through the mediating effect of a negative start-of-workday mood. Moreover, a supervisor’s good night’s sleep (i.e. first-stage moderator) serves as a key mitigating factor to diminish the negative start-of-workday mood resulting from a lack of relaxation, mastery experiences and control experiences (except for the lack of psychological detachment from work) and lessens abusive supervision.

This study contributes to the literature examining off-the-job events to understand the antecedents of abusive supervision that are beyond organizations’ control but significantly influence workplace behaviors, showing that not all antecedents of abusive supervision exist in the workplace; some are transferred from the home domain through nonvisible moods. Finally, the inclusion of sleep quality as a first-stage moderator provides insights on preventing abusive supervision caused by nonwork-related events. This adds a unique dimension to the abusive supervision literature by highlighting factors in the home domain that can prevent negative spillovers to the work domain. The authors conclude with some theoretical and practical implications for researchers and practitioners.

In this work, the authors analyze the dynamic interdependencies between military expenditures and the real economy for the period 1970–2018, and the authors' approach allows for the existence of dominant economies in the system.

In this study, the authors employ a Network General Equilibrium GVAR (global vector autoregressive) model.

By accounting for the interconnection among the top twelve military spenders, the authors' findings show that China acts as a leader in the global military scene based on the respective centrality measures. Meanwhile, statistically significant deviations from equilibrium are observed in most of the economies' military expenses, when subjected to an unanticipated unit shock of other countries. Nonetheless, in the medium run, the shocks tend to die out and economies converge to an equilibrium position.

With the authors' methodology the authors are able to capture not only the effect of nearness on a country's military spending, as the past literature has documented, but also a country's defense and economic dependencies with other countries and how a unit's military expenses could shape the spending of the rest. Using state-to-the-art quantitative and econometric techniques, the authors provide robust and comprehensive analysis.

This paper aims to study the corrosion inhibition behavior of imidazopyridine and its three derivatives on brass.

The authors performed weight loss experiments, electrochemical experiments including the polarization curve and electrochemical impedance spectrum, corrosion morphology observation using scanning electron microscope (SEM) and atomic force microscope (AFM) and surface composition analysis via X-ray photoelectron spectroscopy (XPS) to analyze the corrosion inhibition behavior of imidazopyridine and its three derivatives on brass by using quantum chemical calculation (Gaussian 09), molecular dynamics simulation (M-S) and Langmuir adsorption isotherm.

According to the results, imidazole-pyridine and its derivatives were found to be modest or moderately mixed corrosion inhibitors; moreover, they were spontaneously adsorbed on the metal surface in a single-layer, mixed adsorption mode.

The corrosion inhibition properties of pyrazolo-[1,2-a]pyridine and its derivatives on brass in sulfuric acid solution were analyzed through weight loss and electrochemical experiments. Moreover, SEM and AFM were simultaneously used to observe the corrosion appearance. Furthermore, XPS was used to analyze the surface. Then, Gaussian 09 and M-S were combined along with the Langmuir adsorption isotherm to investigate the corrosion inhibition mechanism of imidazole-[1,2-a]pyridine and its derivatives.
