Using the latest census data (2010), this paper investigates housing poverty conditions in Shanghai, the largest city in China. The data shows that a large fraction of Shanghai households are still living in excessively over-crowded housing. Meanwhile, the incidence ratio of housing poverty among migrants is more than five times than among natives. In particular, 45% of rural migrant households were living in housing poverty. Poverty decomposition analysis shows that approximately 70% of total housing poverty in Shanghai is attributable to rural migrants. Our finding is supported by estimating the multidimensional poverty index (MPI). The findings in this paper have significant implications to general housing policy making in urban China.

The purpose of this paper is to borrow the concept of right-hand person as a specific type of work arrangement and propose a moderated mediation model highlighting the important role of work arrangement in affecting the relationship between abusive supervision and subordinate work outcomes.

The authors tested the hypotheses with a sample of 275 supervisor–subordinate dyads in China (68.8% response rate).

Results showed that if the subordinate was a right-hand person of the supervisor, abusive supervision played a relatively weaker role on the subordinates' performance and organizational citizenship behaviors through leader–member exchange (LMX).

Abusive supervision is a major concern in contemporary organizations, and the current research found that work arrangement such as being a right-hand subordinate could buffer its negative effects. This finding indicates that it is important for organizations and supervisors to make clear work and role assignments.

Abusive supervision has received a lot of research attention in the past decades. On top of the nature of supervisory abusive behaviors, researchers have investigated its antecedents and consequences. However, little is known concerning the roles of the work arrangement for the subordinate that may affect the impact of abusive supervision on subordinate work outcomes. This study empirically tests that being a right-hand subordinate may weaken the negative effect of abusive supervision on subordinate performance and organizational citizenship behaviors, which highlight the importance of work arrangement in studying abusive supervision.

This study aims to examine the effects of the perceived warmth and competence of humanoid robots on customer tolerance of service failure through the affective response and the boundary condition of relationship norms.

Two experimental studies were conducted to investigate the effects of perceived warmth and competence of humanoid robots’ physical appearances on tolerance of service failure and the mediating role of anger. The boundary influence of relationship norms is also explored.

The results reveal that the perception of warmth (vs. competence) robot leads to less (more) anger, which significantly results in tolerance of service failure. However, customer tolerance is insignificant under exchange norms, as the undelivered service violates the expectations of both warm and competent robots.

This study provides practical guidance for hospitality managers to implement humanoid robots in a way that minimizes the negative outcomes of service failure. Managers should also think about the appropriate match of different types of humanoid robots and relationship norms in which robots will be deployed.

This study contributes to the tolerance literature by taking a social cognition perspective to investigate the effect of humanoid robots’ physical appearances on customers’ reactions to service failure. The findings also reveal that its affective mechanism lies in the effect of expectancy violations of service failure on tolerance. Furthermore, this study extends the literature on relationship norms to the influence of company factors on effective humanoid robot implementation.

While the usage of digital technology can bring many operational improvements for firms, it is unclear whether it can effectively improve firm resilience to deal with supply chain disruptions caused by emergencies such as COVID-19. From a dynamic capability perspective, this study aims to investigate how digital technology usage can improve firm resilience in a rapidly changing and turbulent environment.

Based on the survey sample of 237 Chinese firms, the stepwise regression approach was used to examine the proposed research hypotheses.

The empirical evidence shows that digital technology usage has a U-shaped effect on firm resilience, and that effect is fully achieved by first affecting market acuity and then promoting resource reconfiguration. Moreover, the authors further found that the U-shaped association between digital technology usage and firm resilience is derived from the U-shaped association between digital technology usage and market acuity.

This study enriches the resilience literature by revealing the mechanism of digital technology usage’s effects rather than focusing on the role of specific digital technologies. This study also provides guidance for firms to develop effective digital technology usage strategies.

The purpose of this paper is to propose a risk-sharing model to coordinate the decision-making behavior of players in a cassava-based bioethanol supply chain under random yield and demand environment, so as to mitigate the yield and demand uncertainty risk and improve the bioethanol supply chain resiliency and performance.

The decision-making behavior under three models, namely, centralized model, decentralized model and risk-sharing model, are analyzed. An empirical test of the advantages and feasibility of the proposed risk-sharing model, as well as the test of yield uncertainty risk, risk-sharing coefficients and randomly fluctuating cassava market price on the decision-making behavior and performances are provided.

Though the proposed risk-sharing model cannot achieve the supply chain performance in the centralized model, it does help to encourage the farmers and the company to increase the supply of cassava and achieve the Pareto improvement of both players compared to the decentralized model. In particular, these improvements will be enlarged as the yield uncertainty risk is higher.

The findings will help decision makers in the bioethanol supply chain to understand how to mitigate the yield uncertainty risk and improve the supply chain resiliency under yield and demand uncertainty environment. It will also be conducive to ensure the supply of feedstock and the development of the bioethanol industry.

The proposed risk-sharing model incorporates the yield uncertainty risk, the random market demand and the hierarchical decision-making behavior structure of the bioethanol supply chain in the model.

This study mainly aims to examine the mediating effect of perceived organizational support (POS) and the moderating effect of locus of control and job autonomy on the relationship between customer mistreatment behavior and organizational citizenship behavior.

Through a questionnaire survey of 231 employees and their direct supervisors of five hotels in Guangzhou. This paper analyzed five variables (customer mistreatment, POS, locus of control, job autonomy and organizational citizenship behavior) relationships through a variety of data analysis.

Results indicate that customer mistreatment behavior has a negative effect on employees’ organizational citizenship behavior. The relationship between customer mistreatment behavior and employees’ organizational citizenship behavior is partially mediated by employees’ POS. Staffs’ locus of control and job autonomy can modulate the relationship between customers’ mistreatment behavior and POS. Furthermore, the indirect mediating effect of POS on customer mistreatment behavior is revealed. The organizational citizenship behavior linkage is significant only to staff who perceived they have a high level of job autonomy and a high locus of control.

Hotels are advised to provide organizational support and the management of customer mistreatment behavior so as to reflect their employees’ value, seek service innovation and promote production efficiency in practice. Furthermore, it maintains and promotes operational efficiency for service organizations and means the organization pays more attention to meet the social, emotional and psychological needs of its employees.

This article reveals the mechanism relationship between customer mistreatment behavior and employee organizational citizenship behavior. First, it defines the concept of customer mistreatment in the hotel industry and enriches the related research. Second, the study, from the perspective of customer mistreatment, has opened up a new view of organizational citizenship behavior research. Third, we built a research model and it is helpful to grasp the inner mechanism between customer mistreatment and employees’ organizational citizenship behavior. Fourth, this research benefits service organizations so as to maintain and improve their operation efficiency. Furthermore, it can have theoretical guidance for service-oriented organizations to develop a harmonious consumption culture and organizational culture.

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.

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.

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.

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.

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。

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。

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。

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。

Este estudio utiliza la teoría del sistema de eventos y el modelo de demandas de trabajo-recursos (JD-R) para examinar el efecto de doble filo de la fuerza del evento de los Juegos Olímpicos de Invierno de Pekín (BWO) sobre el rendimiento en el rol y el comportamiento proactivo de los voluntarios, mediado por la sobrecarga laboral y la significatividad del trabajo.

Nuestra muestra incluyó 193 díadas de voluntarios-líderes que trabajaban en una sede de BWO. Realizamos un estudio multitemporal y multifuente utilizando Mplus 8 para examinar nuestras hipótesis.

La intensidad percibida por los voluntarios en los eventos de BWO también se relacionó positivamente con la significación del trabajo, que promovió el rendimiento en el rol y el comportamiento proactivo. Además, el apoyo organizativo percibido sirvió como moderador al mitigar la relación positiva entre la intensidad percibida del evento BWO y la sobrecarga de trabajo; sin embargo, no reforzó la relación positiva entre la intensidad percibida del evento BWO y la significatividad del trabajo.

Este estudio desarrolló un modelo integral de cómo la fuerza del evento BWO afectaba al rendimiento de los voluntarios desde la perspectiva de la teoría del sistema de eventos y el modelo JD-R, lo que enriquece la aplicación teórica y la investigación en el contexto de los megaeventos deportivos.

Guided by the cognitive-affective system theory of personality (CAPS), this study aims to investigate the parallel mediating effects of cognitive and affective cynicism on the relationship between illegitimate tasks and employees’ adaptive performance. It also proposes growth need strength as a moderating variable for relationships between illegitimate tasks and employees’ adaptive performance.

Using a time-lagged design, data were gathered from 330 frontline hotel employees in China.

The authors found that the presence of illegitimate tasks is negatively associated with employees’ adaptive performance, this relationship being mediated by cognitive and affective cynicism. Growth need strength weakens the negative impacts of cognitive and affective cynicism on employees’ adaptive performance. In addition, the indirect effect of illegitimate tasks on employees’ adaptive performance via cognitive and affective cynicism is stronger for employees with lower levels of growth need strength.

Hotel managers must heed the negative impact of illegitimate tasks. Furthermore, they should underscore the importance of promoting a harmonious and positive organizational culture and atmosphere. Naturally, hotel managers must also establish effective communication with employees, assisting them in fostering a desire for excellence in their work.

This study provides valuable insights for the hospitality industry by investigating how illegitimate tasks hold sway over hotel employees’ adaptive performance. The study uses a moderated dual-path model to uncover the mechanisms behind this impact and the influence of boundary conditions, thereby expanding the understanding of the topic.

Some indirect evidence indicates that leadership may affect work-related flow, a core concept in positive psychology. However, the exact process of how this relationship takes place is still unknown. Based on the nature of leader-member exchange (LMX), the purpose of this paper is to hypothesize a moderated mediation model of the LMX-flow relationship in which psychological empowerment is the mediator while emotional intelligence (EI) is the moderator.

Two samples are utilized in the study. One sample (n=219) is from the service industry representing a high emotional labor job, and the other sample (n=208) is from the manufacturing industry representing a low emotional labor job.

In both the samples, psychological empowerment mediates the positive relationship between LMX and work-related flow. However, the moderated mediation effect of EI is supported only in the service sample but not in the manufacturing sample.

Leader plays an important role in facilitating subordinates’ flow experience by enhancing psychological empowerment. For the high emotional labor job, employees with high EI are better able to transfer leader’s support into flow experience.

The paper, as the first study to connect LMX with flow concept, advances the study of positive psychology in workplace context, especially the leadership field. By proposing a mediating mechanism and outlining EI as a moderator, the study explains how LMX relates to flow experience at work.

Wall climbing robots' volume is needed to be very small in fields that workspace is limited, such as anti‐terror scouting, industry pipe network inspecting and so on. The purpose of this paper is to design a miniature wall climbing robot with biomechanical suction cups actuated by shape memory alloy (SMA) actuators.

Based on characteristics of biologic suction apparatuses, the biomechanical suction cup is designed first. Theory analysis of the suction cup is made considering elastic plate's deflection and SMAs constitutive model. A triangular close linkage locomotion mechanism is chosen for the miniature robot because of its simple structure and control. The robot's gait, kinematics, and control system are all illustrated in this paper.

Experiments indicate that the suction cup can be used as an adhesion mechanism for miniature wall climbing robots, and the miniature robot prototype with biomechanical suction cups can move in straight line and turn with a fixed angle on an inclined glass wall.

This paper describes how a miniature wall climbing robot with biomechanical suction cups actuated by SMA without any air pump is designed.
