The negative interpersonal interaction between customers and platform gig workers has become a problem for platform owners and government. This study investigates the role of negative customer treatment in the context of gig work and its impact on gig workers’ sabotage behavior. A questionnaire survey approach was used in the study, collected three-wave survey data from 258 Chinese gig workers including food-deliver platform workers and app-based ride-hailing drivers. Both effects of the mediation and moderation were tested, all of which find support, using hierarchical multiple regression by SPSS22.0. Results indicate that negative customer treatment can also predict gig workers’ service sabotage through work meaningfulness. Furthermore, positive customer treatment acted as an effective safeguard against the effects of negative customer treatment on employee service sabotage. Trait psychological resilience can also mitigate the effects of a low level of work meaningfulness. The manuscript’s focus provides an interesting angle to the previous research, especially the inclusion of work meaningfulness and trait resilience, on negative customer treatment in the context of gig work. This study contributes to further broaden the perspective of conservation of resource theory for individual intrinsic motivation analysis. Practical implications for platform management and government governance have also been discussed in this manuscript.

To identify the common and specific structural basis of bipolar depression and unipolar depression is crucial for clinical diagnosis. In this study, a total of 85 participants, including 22 BD patients, 36 UD patients, and 27 healthy controls, were enrolled. A voxel-based morphology method was used to identify the common and specific changes of the gray matter volume to determine the structural basis. Significant differences in GMV were found among the three groups. Compared with healthy controls, UD patients showed decreased GMV in the orbital part of the left inferior frontal gyrus, whereas BD patients showed decreased GMV in the orbital part of the left middle frontal gyrus. Compared with BD, UD patients have increased GMV in the left supramarginal gyrus and middle temporal gyrus. Our results revealed different structural changes in UD and BD patients suggesting BD and UD have different neurophysiological underpinnings. Our study contributes toward the biological determination of morphometric changes, which could help to discriminate between UD and BD.

Based on social information processing theory, we provide a novel theoretical account of how and when leader humor influences subordinate boundary-spanning behavior. We develop a moderated mediation model explicating the mechanism of psychological safety and the boundary condition of subordinate interpersonal influence. Using multiwave data, we tested our research hypotheses with a sample of 452 members from 140 teams in a Chinese information technology company. Results showed that leader humor positively affects subordinate boundary-spanning behavior via increased psychological safety. Moreover, this mediated effect is stronger when subordinates have high interpersonal influence. These findings offer theoretical and practical insights into boundary-spanning activities and leader humor, which we discuss.

Aiming at the problems of poor adaptability and low secret key generation rate of secret key generation scheme based on single characteristic parameter of wireless channel, a secret key generation method based on joint characteristic parameters of amplitude and phase of wireless channel is proposed. This method is based on the single-eavesdropping wireless fading channel model; the joint characteristic model of amplitude and phase of wireless fading channel is established; it detects and extracts the joint characteristic parameters of amplitude and phase of channel, and then the proposed characteristics are quantified by using the equal probability joint quantization strategy of amplitude and phase to generate the secret key random parameters. In this paper, the amplitude and phase joint feature parameter detection method of wireless channel can not only improve the generation rate of random secret key parameters but also make the eavesdropping party’s eavesdropping error rate closer to 0.5. The test results show that the proposed scheme can significantly improve the rate, reliability, and security of generating key random parameters.

In the 1990s, China created a research evaluation system based on publications indexed in the Science Citation Index (SCI) and on the Journal Impact Factor. Such system helped the country become the largest contributor to the scientific literature and increased the position of Chinese universities in international rankings. Although the system had been criticized by many because of its adverse effects, the policy reform for research evaluation crawled until the breakout of the COVID-19 pandemic, which accidently accelerates the process of policy reform. This paper highlights the background and principles of this reform, provides evidence of its effects, and discusses the implications for global science.

In this article, the author uses a narrative-semiotic approach to discuss the Eight Revolutionary Model Plays of China's Cultural Revolution, which left profound but sometimes negative influences on the lives of Chinese people. Because of the political upheavals of the time, the Eight Revolutionary Model Plays dominated the cultural stage during this special period of Chinese history. However, they have become popular again in recent years — an interesting cultural phenomenon that deserves academic observation Phelan's three narrative voices (mimetic, thematic, and synthetic) are used for narrative analysis and it is determined that these model plays primarily use the thematic voice. Jakobson's semiotic theory of six factors within the speech event is used for semiotic analysis and the result is that each of the six factors has polyphonic features. The conclusion is that although the plays were originally made for political purposes, with time as well as people's appreciation and consumption they have become part of Chinese culture. In this sense, one can say that art, like language, is also a kind of convention.
