Abstract
Purpose
In this meta-analysis, the authors investigate the relationship between self-construal and conflict management strategies and shed light on the inconsistent findings in the literature. Moreover, they examine the mediating role of face concerns in this relationship. Importantly, the present meta-analysis is the first to test the assumptions of face-negotiation theory with the meta-analytic structural equation modeling (MASEM), which enabled the authors to test the hypothesized relationships in one single model.
Design/methodology/approach
The authors used the method of MASEM to test the relationship between self-construal and conflict management and assess the mediating role of face concerns. In this regard, the authors employed one-stage meta-analytic structural equation modeling to perform MASEM and its moderators.
Findings
Two hundred fifty-four effect sizes based on thirty-three studies were pooled in this meta-analysis. The authors found that individuals with stronger independent self-construal and stronger self-face concerns were more likely to use forcing. Moreover, the relationship between independent self-construal and forcing was mediated by self-face concerns. Individuals with a stronger interdependent self-construal and individuals with stronger other-face concerns were more likely to use problem-solving and yielding. The relationship between interdependent self-construal and problem-solving and yielding was mediated by other-face concerns. Finally, interdependent self-construal also had an indirect effect, via other-face concern, on avoiding and compromising.
Originality/value
The present meta-analysis is the first effort that the authors are aware of to test the assumptions of face-negotiation theory (FNT) using MASEM method. The authors used one-stage meta-analytic structural equation modeling viewed as the state of the methods to perform MASEM and its moderators. They employed full information meta-analytic structural equation modeling to show the generalizability and heterogeneity of structural equation modeling parameters. They applied studentized deleted residuals to assess outlier analysis and also conducted different methods to perform MASEM to check the robustness of the findings resulted. Finally, the current study adds multiple methods of assessing for publication bias.

Abstract
This research explores two interconnected questions: (1) How do we approach stylistic features of multimodal rhetorical artifacts such as protest posters? (2) Do said artifacts designed for different purposes exhibit systematic stylistic differences? Drawing on Charles Sanders Peirce’s semiotic categorization, this study develops a framework for examining concision, one of the primary stylistic considerations for multimodal rhetorical artifacts such as protest posters. This paper illustrates the use of this framework by exploring the correlation between rhetorical purpose and concision in posters created and disseminated before and during the 2011–2012 Québécois student movement. This study fine-tunes our existing knowledge on multimodality with style sensitivity, and demonstrates how an economy-of-sign based semiotic approach could enrich the empirical examination of multimodal rhetorical artifacts by generating more controlled interpretations.

Abstract
Purpose
The purpose of this paper is to study the preload range of tendon-driven manipulator and the relationship between preload and damping. The flexible joint manipulator (FJM) with joint flexibility is safer than traditional rigid manipulators. A FJM having an elastic tendon is called an elastic tendon-driven manipulator (ETDM) and has the advantages of being driven by a cable and having a more flexible joint. However, the elastic tendon introduces greater residual vibration, which makes the control of the manipulator more difficult. Accurate dynamic modeling is effective in solving this problem.
Design/methodology/approach
The present paper derives the relationship between the preload of the ETDM and the friction moment through the analysis of the forces of cables and pulleys. A dynamic model dominated by Coulomb damping is established.
Findings
The linear relationship between a decrease in the damping moment of the system and an increase in the ETDM preload is verified by mechanics analysis and experiment, and a curve of the relationship is obtained. This study provides a reference for the selection of ETDM preload.
Originality/value
The method to identify ETDM damping by vibration attenuation experiments is proposed, which is helpful to obtain a more accurate dynamic model of the system and to achieve accurate control and residual vibration suppression of ETDM.

Abstract
Research has overwhelmingly focused on the positive side of leadership in the past. However, research into negative aspects of leadership is picking up pace. This chapter will provide an overview of two prominent aspects of negative leadership, namely, abusive supervision and laissez-faire leadership. Research has shown that both types of leadership have significant negative consequences both for organisations as a whole as well as individual followers. Examples include lower job satisfaction, stress, as well as lowered performances and a higher likelihood of counter-productive work behaviour. Both abusive supervision and laissez-faire researchers acknowledge that these leadership styles take effect through the perception of followers. That is, they consider that the same behaviour can be interpreted differently by different followers and will, hence, lead to different follower-related outcomes. Abusive supervision and laissez-faire are, however, very different in terms of the actual leader behaviours described. While abusive supervision is a style that is actively destructive, laissez-faire is destructive via lack of support for followers' goal achievement. We end the chapter with an outlook for future research, notably an attempt to systematise future research into destructive leadership with respect to the different forms it can take.

Abstract
Purpose
Safety is an important issue when manipulators operate in an environment where humans are present, such as the agriculture industry. An intrinsically safe mechanical system guarantees human safety when electronics or controls fail. However, industry also demands a certain operating velocity. A low inertia is the most important aspect to combine safety with a useful operating velocity, because this will limit the amount of kinetic or potential energy in the system and the required actuation forces. Low‐actuation forces limit the amount of static contact pressure between manipulator and human, a requirement for intrinsic safety. Low energy means that less contact force is required to put the manipulator to a stop in collision, an additional requirement. The goal of this paper is to find the maximum industrially applicable, manipulator mass for which intrinsic mechanical safety is guaranteed.
Design/methodology/approach
Observing existing and proposed manipulators in agriculture results in a required cycle time of 0.9 s, trajectory of 0.8 m and payload of 2 kg. Three important trade‐offs applying to the manipulator are identified. The first is between maximum velocity and acceleration, using cycle time and trajectory. The second is between maximum acceleration and mass, based on a measure for pain in contact pressure. The third is between maximum velocity and mass, using a collision model and the contact pressure during collision.
Findings
Combining all three trade‐offs results in an allowable arm effective inertia of 5.1 kg. Taking payload into account and converting to a realistic mass distribution results in a total mass of 9.3 kg. Compared to existing manipulators, both mass and payload are ambitious but realistic for the future development of an intrinsically safe manipulator.
Research limitations/implications
Accuracy in positioning is not taken into account.
Originality/value
This paper combines safety criteria on maximum energy and maximum static pressure, while also taking industrial applicable operating velocity into account.

Abstract
Purpose
The present research aims to empirically test the “Barriers to abusive supervision model” to find how employee-related (core self-evaluations) and situational factors (perceived job dependency) make an employee trapped in the spiral of supervisory abuse. In addition, the work–family spillover lens is used to explain how employees' retaliation is targeted at their families in response to abuse from their bosses.
Design/methodology/approach
The current study has employed a three-wave longitudinal moderated mediation design and analysed data from 265 employees working in the hospitality industry of Pakistan.
Findings
The results of this study have shown that low core-self evaluations put employees in a spiral of supervisory abuse and they instil aggression towards their families. This association is further strengthened when employees are dependent on their job.
Originality/value
This study is one of the first to use the “Barriers to Abusive supervision” model to answer who and in which conditions tend to trap in the spiral of abuse and integrate the work-to-family interface model for elaborating the outcomes to the family domain.

The paper aims to present a new mechanical scheme for a leg to be included in legged vehicles that simplifies the control actuations along the stride.
Abstract
Purpose
The paper aims to present a new mechanical scheme for a leg to be included in legged vehicles that simplifies the control actuations along the stride.
Design/methodology/approach
The scheme includes three four‐bar links grouped in two mechanisms. The first one decouples the vertical and horizontal foot movements. The second one produces a constant horizontal foot velocity when the corresponding motor is given a constant speed. A hybrid robot with wheels at the end of the hind legs has been simulated and constructed to validate the leg performance.
Findings
The gait control requires only five commands for the electronic cards to control the leg. Decoupling vertical and horizontal movements allows a more adequate selection of actuators, a reduction of energy consumption, and higher load capacity and robot velocity. Additional mechanical benefits, such as improved robustness and lower inertia, are obtained. The hind legs can also be articulated, allowing the robot to overcome an obstacle and to climb up and down stairs.
Research limitations/implications
A hybrid robot offers greater stability with respect to a legged robot. This way the lateral movement is not a concern, and therefore it has not been tested yet during the walking cycle.
Originality/value
This new scheme obtains a quasi‐Cartesian behaviour for the foot movement that drastically simplifies the control of the walking cycle. Although the decoupling between movements has already been obtained in previous configurations, these follow a pantograph structure and suffer from blocking problems when they are subject to lateral forces. These schemes were suitable for crab‐like gaits. The proposed leg moves according to a mammal‐like gait.

Abstract
Purpose
The purpose of this paper is to propose a spatial six‐link RRCCRR (where R denotes a revolute joint, and C denotes a cylindric joint) mechanism to be used as the mechanism body of a biped robot with three translations (3T) manipulation ability.
Design/methodology/approach
This biped RRCCRR mechanism can reach any position on the ground by a crawling mode or alternatively, a somersaulting mode. After the robot reaches a designated position, it can work in manipulation mode. Mobility, walking mode, kinematic and stability analyses are performed, respectively.
Findings
Based on this biped RRCCRR mechanism, a biped 3T lifter which can be used in industry is designed and analyzed. Finally, the proposed concept is verified by experiments on a prototype.
Originality/value
The work presented in this paper is one of new explorations to apply traditional spatial linkage mechanisms to the field of biped robots, and is also a new attempt to use the biped robot, that is generally used in the field of bionic robots, as a mobile manipulator robot platform in industry.

Abstract
Purpose
The purpose of this paper is to examine bystanders’ supervisor-directed deviance to vicarious abusive supervision by supervisor-directed attribution. Furthermore, this study developed a moderated–mediation model to explore how LMX between bystander and his/her supervisor moderate the relationship between vicarious abusive supervision and the supervisor-directed attribution, which subsequently influences bystanders’ supervisor-directed deviance.
Design/methodology/approach
The paper tested the model using a sample of 336 workers using a two-wave survey. A moderated–mediation analysis was conducted with bootstrapping procedure to test the first stage moderated–mediation model in this study.
Findings
The results showed that LMX (between bystander and his/her supervisor) weakens the indirect relationship between vicarious abusive supervision and supervisor-directed deviance by bystanders’ supervisor-directed attribution.
Practical implications
Leadership training programs should be conducted to caution supervisors in terms of the deleterious consequences of vicarious abusive supervision. Organizations also should plan perception and communication training courses for leaders; such training would reduce bystanders’ responsibility attribution to them by providing timely explanations and communication. Furthermore, organizations should monitor supervisors by managers’ performance appraisal and formulate rules to punish abusive managers.
Originality/value
These results clarify the nature and consequences of LMX (dyadic relationships of bystanders–supervisor) for bystanders’ attribution process, and explain underlying attributional perceptions and reactions to vicarious abusive supervision. This study provides a more nuanced understanding of when and how vicarious abusive supervision leads to bystanders’ supervisor-directed deviance.

Abstract
Purpose
Most people live in cities and work in offices, two contexts offering many lifestyle-related and environmental health risks. To advance their health, this paper aims to introduce an analogy between urban design and facility design to explore whether health-directed design interventions in cities and facilities are related and to look for applicable cross-overs and opportunities to develop the facility management (FM) profession on the urban level.
Design/methodology/approach
The principles of abductive reasoning as a first phase of scientific investigation were followed, by introducing a new idea and attentively observing phenomena in the communities of FM and urban design. The method was desk research, in the context of discovery.
Findings
Many possible cross-overs exist which offer opportunities for urban planners and facility managers to reinforce each other and interesting market opportunities for the further development of urban FM. However, more systematic research is needed on efficacious and effective interventions. Furthermore, experiences and capacities of the FM sector should be unlocked and applied within a city context, as the knowledge and experiences of facility managers and urban planners can create synergy.
Practical implications
The findings are directly applicable to facility and urban design practices and to FM education by involving students in city design practices.
Originality/value
Cross-overs between facilities and cities are new and can inspire both facility managers and urban planners to work together more closely for the benefit of citizens and employees.
