Abstract
Purpose
This study aims to use event system theory and job demands–resources (JD-R) model to examine the double-edged sword effect of event strength of Beijing Winter Olympics (BWO) on volunteers’ in-role performance and proactive behavior as mediated by work overload and meaningfulness.
Design/methodology/approach
The sample included 193 volunteer–leader dyads working at one BWO venue. The authors conducted a multitime and multisource study using Mplus 8 to examine the hypotheses.
Findings
Volunteers’ perceived BWO event strength was positively related to work overload, which reduced in-role performance and proactive behavior. Volunteers’ perceived BWO event strength was also positively related to work meaningfulness, which promoted in-role performance and proactive behavior. Perceived organizational support served as a moderator by mitigating the positive relationship between perceived BWO event strength and work overload; however, it did not strengthen the positive relationship between perceived BWO event strength and work meaningfulness.
Originality/value
This study developed a comprehensive model of how BWO event strength affected volunteers’ performance from the perspective of event system theory and the JD-R model, which enriches theoretical application and research in the context of mega sport events.
研究目的
本研究运用事件系统理论和工作需求-资源(JD-R)模型, 探讨了2022年北京冬奥会(BWO)事件强度通过工作负荷和工作意义感知进而对志愿者角色内绩效和主动性行为的双刃剑效应。
研究设计
我们在冬奥会场所之一实施了多时点、多来源的收集数据的方式, 最终样本包括193份志愿者-领导配对数据, 并使用Mplus 8来检验我们的假设。
研究发现
志愿者感知的BWO事件强度与工作负荷呈正相关, 进而会降低他们的角色内绩效和主动性行为。志愿者感知的BWO事件强度与工作意义感也呈正相关, 进而会促进他们的角色内绩效和主动性行为。感知的组织支持通过弱化BWO事件强度与工作负荷之间的正相关关系, 进而调节了志愿者的角色内绩效和主动性行为; 然而, 感知的组织支持并没有强化BWO事件强度与工作意义感之间的正相关关系。
原创性
本研究结合事件系统理论和JD-R模型, 发展了一个BWO事件强度对志愿者绩效表现影响的综合模型, 丰富了有关大型体育赛事志愿者的理论应用和研究。

Abstract
Purpose
Applying affect-as-information theory, this research analyzed the relationship of leader affective presence and employee proactive customer service performance (PCSP) in hospitality organizations. It further explored when and how leader affective presence influenced employee PCSP.
Design/methodology/approach
Taking a sample of 110 teams with 361 pairs of leaders and employees in Chinese hotels, a moderated mediation model was tested across individual and team levels using hierarchical linear modeling.
Findings
This study found that leader positive affective presence (LPAP) had a positive effect on employee PCSP, whereas leader negative affective presence (LNAP) had a negative effect on employee PCSP. Employee prosocial motivation mediated the relationship between leader affective presence and employee PCSP. The employee power distance value weakened the LNAP–employee prosocial motivation relationship, which subsequently mitigated the negative indirect effect of LNAP on employee PCSP through employee prosocial motivation.
Research limitations/implications
The sample was drawn from one hotel group in China, which may limit external validity.
Practical implications
Hospitality organizations should emphasize the affective traits of leaders in employee initiatives. Leader affective presence should be considered during recruitment and promotion. Management should pay more attention to employee emotional management and value alignment.
Originality/value
The findings provide deeper insight into the role of LPAP and LNAP in influencing employees’ PCSP. It sheds new light on the mechanisms and conditions through which leader affective presence might heighten or hinder employee PCSP.

Abstract
Purpose
Although employee overqualification is a common occurrence in the workplace, most research has focused on overqualification at the individual level rather than at the team level. Drawing on social cognitive theory, this study aimed to uncover how leaders' perception of team overqualification influenced their cognition and follow-up behavior.
Design/methodology/approach
We performed two studies to test our model. In Study 1, we conducted an experiment to examine the causal relationship between leaders' perception of team overqualification and leadership self-efficacy. In Study 2, a two-wave field study was conducted to test the overall model based on a sample obtained from a steel company in China.
Findings
We found that leaders' perception of team overqualification reduced leadership self-efficacy, which in turn hindered leaders' empowering behavior. In addition, leaders' social face consciousness strengthened the negative relationship between leaders' perception of team overqualification and leadership self-efficacy, such that the relationship was more negative when leaders' social face consciousness was high rather than low.
Originality/value
Our study contributes to the literature on employee overqualification and its effects on leaders through investigation at the team level to show how leaders respond to overqualified teams.

Abstract
Purpose
The purpose of this study is to establish a finite element (FE) model with the random distribution of the Nylon12/hydroxyapatite (PA12/HA) composite material in selective laser sintering (SLS) process for considering the material anisotropy, which aims to obtain the law of temperature and stress changes in PA12/HA sintering.
Design/methodology/approach
By using python script in Abaqus, the FE model is established in which the two materials are randomly distributed and are assigned to their intrinsic temperature-dependent physical parameters. Molten pool sizes at various process parameters were evaluated in terms of numerical simulation and scanning electron microscope analysis, identifying a good agreement between them. Evaluation of temperature and stress distribution under the condition of different HA contents was also conducted.
Findings
It shows that the uneven distribution and quantity of HA powder play a vital role in stress concentration and temperature increase. Additionally, the influence of HA addition on the mechanical performance of SLS-fabricated parts shows that it is conducive to improve compressive strength when the HA ratio is less than 5% because an excess of HA powder tends to bring about a certain amount of microspores resulting in a decrease in part density.
Originality/value
The FE model of the PA12/HA composite material with parameterized random distribution in SLS can be applied in other similar additive manufacturing technologies. It provides a feasible guideline for the numerical analysis of properties of composite materials.

Abstract
This paper considers the problem of estimating a partially linear varying coefficient fixed effects panel data model. Using the series method, we establish the root N normality for the estimator of the parametric component; and we show that the unknown function can be consistently estimated at the standard nonparametric rate. Furthermore, we extend the model to allow endogeneity in the parametric component and establish the asymptotic properties of the semiparametric instrumental variable estimators.

The purpose of this paper was to study some effective evaluation methods for the biocide performance on sulfate-reducing bacteria (SRB) biofilm.
Abstract
Purpose
The purpose of this paper was to study some effective evaluation methods for the biocide performance on sulfate-reducing bacteria (SRB) biofilm.
Design/methodology/approach
The most probable number method, electrochemical impedance spectroscopy (EIS) measurements, scanning electron microscopy (SEM), three-dimensional (3D) photos and epifluorescent microscopy were used in this study.
Findings
The results showed that the minimum inhibitory concentrations and minimum bactericidal concentrations of them to sessile SRB were greatly more than planktonic SRB. The EIS of the two biocides indicated that the biofilm exposed to higher concentrations of biocide were much more compact and flat, which perfectly coincided with the SEM, 3D photos and the epifluorescent microscopies.
Originality/value
In this paper, it, thus, appears that these methods evaluating biocide performance on the SRB biofilm were really effective by comparing the performance of bis-quaternary ammonium salt (BAQS) and tetrakis hydroxymethyl phosphonium sulfate.

This paper aims to propose a general framework of shared control for human–robot interaction.
Abstract
Purpose
This paper aims to propose a general framework of shared control for human–robot interaction.
Design/methodology/approach
Human dynamics are considered in analysis of the coupled human–robot system. Motion intentions of both human and robot are taken into account in the control objective of the robot. Reinforcement learning is developed to achieve the control objective subject to unknown dynamics of human and robot. The closed-loop system performance is discussed through a rigorous proof.
Findings
Simulations are conducted to demonstrate the learning capability of the proposed method and its feasibility in handling various situations.
Originality/value
Compared to existing works, the proposed framework combines motion intentions of both human and robot in a human–robot shared control system, without the requirement of the knowledge of human’s and robot’s dynamics.

Abstract
Purpose
The purpose of this paper is to examine the nature of the China–North Korea alliance that has been often described as “Lips and Teeth” or “Blood Tied.”
Design/methodology/approach
In order to make accurate assessment of the China–North Korea relations, this paper conducts indepth historical analysis of the relations. The relations between two countries were formed in 1940s and lasts until today.
Findings
However, by looking into the history of two countries, this paper argues that the bilateral relations are not an extraordinary but an ordinary state-to-state relations dictated by national interests. Changes in their calculus of national interests affect their relations. They cooperate with each other when they see mutual benefit in doing so and tension arises when there is a conflict of interests. What should be noted is that the changes in the nature of relations is different from the deterioration in the relations. Recent improvement of their relations supports this paper’s argument.
Originality/value
This paper suggests new look at the China–North Korea relations that has been considered as an extraordinary relations. The findings of this paper suggest that the alliance relation is not different from other state-to-state relations where conflict and cooperation occurs based on their national interests.
