This study explores the potential impact of enterprise social media (ESM) communication visibility on knowledge sabotage to reduce knowledge sabotage within organizations.

We collected data from 389 Chinese employees across three stages and used hierarchical regression analysis and the bootstrap method to test our hypotheses.

Communication visibility negatively affects knowledge sabotage, and the loss of knowledge power mediates the relationship between communication visibility and knowledge sabotage. Digital work connectivity strengthens the negative relationship between message transparency and loss of knowledge power but weakens the negative relationship between network translucence and loss of knowledge power. Therefore, digital work connectivity plays a dual role.

Managers can encourage employees to share their knowledge advantages through ESM and seek cross-disciplinary knowledge cooperation, which helps restrain knowledge sabotage from the source. At the same time, maintaining appropriate digital work connectivity enables employees to leverage their knowledge interaction advantages of ESM, thereby fostering their knowledge competitiveness.

This study is the first to reveal the internal mechanism (loss of knowledge power) through which ESM communication visibility affects knowledge sabotage and explores the boundary condition (digital work connectivity) impacting the effectiveness of communication visibility. It contributes to a deeper understanding of the inherent nature of knowledge sabotage from an information technology perspective and offers novel technical insights into its management.

This study aims to investigate the negative interpersonal antecedents, emotional mediators and boundary conditions of knowledge sabotage behavior.

The authors collected data from 275 Chinese employees using convenience sampling and snowball sampling across three stages. Subsequently, the authors used both hierarchical regression and bootstrap methods to test the proposed hypotheses.

The results confirmed that workplace ostracism has positive effects on employee knowledge sabotage behavior both directly and via employee anger. In addition, the authors found that employee bottom-line mentality (BLM) moderates not only the direct effect of workplace ostracism on employee anger but also the indirect effect of employee anger in this context. Employee conscientiousness moderates only the direct effect of workplace ostracism on employee anger and does not moderate the indirect effect.

To the best of the authors’ knowledge, this study not only explores the influence of workplace ostracism on employee knowledge sabotage behavior for the first time but also elucidates the underlying emotional mechanisms (anger) and boundary conditions (employee BLM and conscientiousness) by which workplace ostracism influences employee knowledge sabotage behavior, thus deepening the understanding of how knowledge sabotage emerges in organizations.

This study aims to build an integrative framework for explaining society's information access disparity, which takes both structure and agency as well as their interactions into consideration.

It adopts a qualitative survey design. It collects data on the development of 65 individuals' information access through interviews, and analyzes the data following grounded theory principles.

A theoretical framework is established based on seven constructs and their relationships, all emerging from the empirical data. It rediscovers practice as the primary structural force shaping individuals' information access, hence society's information access disparity; it shows, meanwhile, that the effect of practice is mediated and/or interrupted by four agentic factors: affective responses to a practice, strategic move between practices, experiential returns of information, and quadrant state of mind.

It urges LIS researchers to go beyond the embedded information activities to examine both the embedded and embedding, beyond actions to examine both actions and experiences.

It calls for information professionals to take a critical stance toward the practices they serve and partake in their reforms from an LIS perspective.

The framework provides an integrative and novel explanation for information access disparity; it adds a number of LIS-relevant concepts to the general practice theories, highlighting the significance of embedded information activities in any practice and their reverberations; it also appears able to connect a range of human-related LIS theories and pinpoint their gaps.

The aim is to focus on an automated management and evaluation system to control the operation of community health service (CHS) efficiently.

On the basis of analyzing existing health laws, regulations, CHS work situation, the authors established the execution method and supervision norm of management for CHS. They used Delphi expert consultation activity and analytic hierarchy process to construct weight coefficient allocation list and synthesize evaluation models: GI=∑_I=1^NCiPi. The authors synthesized computer technology to design corresponding software, and then completed the spot usage.

The automated management and evaluation system for CHS has been completed. The system possesses automated management function, automated evaluation function, searching function, the functions of supervision and statistics analysis as well as the feedback. Automated management includes guide and filling‐in, checking‐up, modifying and saving, converging, submitting, examining and approving, receiving, saving to file and issuing formation, etc. Automated evaluation can rank automatically synthesized index or any selected single criterion index in the order of either high to low or low to high. The feedback function is able to be used to convey timely the state of execution, and to offer the bases for further adjustment.

The automated evaluation makes the difficult evaluation work of daily supervision simple and maneuverable.

The systemization and automation of CHS management can control effectively practical operation of CHS.

The study is the first to establish an automated compliance management and evaluation system for Chinese CHS.

The purpose of this paper is to present a method for the environmental impact analysis of machine-tool cutting, which enables the detailed analysis of inventory data on resource consumption and waste emissions, as well as the quantitative evaluation of environmental impact.

The proposed environmental impact analysis method is based on the life cycle assessment (LCA) methodology. In this method, the system boundary of the cutting unit is first defined, and inventory data on energy and material consumptions are analyzed. Subsequently, through classification, five important environmental impact categories are proposed, namely, primary energy demand, global warming potential, acidification potential, eutrophication potential and photochemical ozone creation potential. Finally, the environmental impact results are obtained through characterization and normalization.

This method is applied on a case study involving a machine-tool turning unit. Results show that primary energy demand and global warming potential exert the serious environmental impact in the turning unit. Suggestions for improving the environmental performance of the machine-tool turning are proposed.

The environmental impact analysis method is applicable to different machine tools and cutting-unit processes. Moreover, it can guide and support the development of green manufacturing by machinery manufacturers.

The purpose of this paper is to propose a modified fuel-balanced formation keeping strategy based on actively rotating satellites in the formation in the J2 perturbed environment.

Based on the relative orbital elements theory, the J2 perturbed relative motions between different satellites in the formation are analyzed, and then, the method to estimate fuel required to keep the in-plane and out-of-plane relative motions is presented, based on which a modified fuel-balanced formation keeping strategy is derived by considering both in-plane and out-of-plane J2 perturbations.

Numerical simulations demonstrate that the modified fuel-balanced formation keeping strategy is valid, and the modified fuel-balanced formation keeping strategy requires less total fuel consumption than original Vadali and Alfriend’s method.

The modified fuel-balanced formation keeping strategy is valid for formation flying mission whose member satellite is in circular or near-circular orbit.

The modified fuel-balanced formation keeping strategy can be used to solve formation flying keeping problem, which involves multiple satellites in the formation.

The modified fuel-balanced formation keeping strategy is proposed by considering both in-plane and out-of-plane J2 perturbations, which further reduce the fuel consumption than the original Vadali and Alfriend’s method.

The purpose of this paper is to present a method to achieve small satellite formation keeping operations by using the differential lift and drag to control the drift caused by J2 perturbation in circular or near-circular low earth orbits (LEOs).

Each spacecraft is equipped with five large flat plates, which can be controlled to generate differential accelerations. The aerodynamic lift and drag acting on a flat plate is calculated by the kinetic theory. To maintain the formation within tracking error bounds in the presence of J2 perturbation, a nonlinear Lyapunov-based feedback control law is designed.

Simulation results demonstrate that the proposed method is efficient for the satellite formation keeping and better accuracy advantage in comparison with classical approaches via the fixed maximum differential aerodynamic acceleration.

Because the aerodynamic force will reduce drastically as the orbital altitude increases, the formation keeping control strategy for small satellites presented in this paper should be limited to the scenarios when satellites are in LEO.

The formation keeping control method in this paper can be applied to solve satellite formation keeping problem for small satellites in LEO.

This paper proposes a Lyapunov control strategy for satellite formation keeping considering both lift and drag forces, and simulation results show better performance with high accuracy under J2 perturbation.

Traditional switching harmonic suppressor design methods require domain experts to adjust design parameters due to various complex performance requirements and practical limitations in switching ripple suppressor designs. The purpose of this paper is to present a method for filter parameter design.

An improved non-dominated sorting genetic algorithm II (NSGA II) was used in the inductor-capacitor-inductor (LCL) filter design to find the optimal design parameters, and a method was proposed to handle the constraints by transforming the them into decision variables.

The performance of the proposed algorithm in parameter designing was verified by simulation on MATLAB and experimental results on hardware-in-the-loop plat-form with StarSim software. The results indicate that the optimization algorithm has a better effect than the traditional expert parameters on each optimization index, especially on the switching harmonic suppression.

The paper presents an improved multi-objective optimization algorithm with ingenious constraints handing to obtain better filter parameters and reduces switching harmonics.

This study provides empirical support for the cultural economics model between executive team and firm performance and offers important implications for policy selection and appointment of managers in China.

From the perspective of relationship embeddedness, the authors explore the impact of management geographical proximity (GP) on stock price crash risk in China. Using archival data from China's unique dataset about birthplace culture, the authors find that management GP experiences a large increase in corporate stock price crash risk for the period 2009–2018.

The impact of management GP on stock price crash risk is more pronounced when the company is located in areas with weaker formal legal environment and stronger Confucian culture. Furthermore, the impact has a significant links with firm characteristics such as information transparency, over-investment and tax aggressiveness.

First, the research extends the literature on the empirical determinants of stock price crash risk. These studies focus on formal institution, not on informal institution, such as relational culture. Second, the research provides evidence for economic consequences on relational governance from executive birthplace culture to explore the economic consequences of geographical relational governance but takes stock price crash risk to present executives' behavior strategies and market reaction via exploring asymmetrical variation of market stock price. Finally, the paper provides reference to corporate governance arrangement and executive appointment.

This study examines how unilateral supplier transaction-specific investments (TSIs), directly and indirectly, influence international buyer opportunism and the extent to which detailed contracts enable suppliers to safeguard against international buyer opportunism. The study also examines whether relationship length affects the efficacy of detailed contracts in cross-border outsourcing relationships.

The hypotheses are tested by using data collected from multiple informants working for 229 manufacturing suppliers in China. Multiple regression with a three-way interaction is used to test the hypotheses.

Unilateral supplier TSIs encourage international buyer opportunism through increased supplier dependence. Contract specificity negatively moderates the effect of supplier dependence on international buyer opportunism. This moderating effect is stronger in long-term cross-border buyer–supplier relationships than in short-term ones.

The current study extends the cross-border outsourcing literature by examining how emerging-market suppliers in a weak power position can proactively safeguard against international buyer opportunism by using detailed contracts. Our findings show that supplier dependence mediates the relationship between unilateral supplier TSIs and international buyer opportunism; detailed contracts, however, can help dependent suppliers safeguard against international buyer opportunism. In particular, the findings highlight the importance of long-term buyer–supplier relationships that enhance the efficacy of detailed contracts.
