Objectives: The corona virus disease-2019 pandemic spread globally, and we aimed to investigate the psychosocial impact on healthcare workers in China during the pandemic.Methods: In this systematic review and meta-analysis, we searched seven electronic databases for cross-sectional studies on psychosocial impact on HWs in relation to COVID-19 from January 1, 2020 to October 7, 2020. We included primary studies involving Chinese HWs during the pandemic, and data were extracted from the published articles. Our primary outcome was prevalence of anxiety, depression, and stress disorders. We pooled prevalence value with their 95% confidence interval using random effect models and assessed study quality on the basis of an 11-item checklist recommended by the Agency for Healthcare Research and Quality. The study protocol was registered in PROSPERO.Results: We identified 25 articles comprising a total of 30,841 completed questionnaires and 22 studies for meta-analysis. The prevalence of anxiety, depression, and stress disorders was 34.4%, 31.1%, and 29.1% for HWs. The pooled prevalence of anxiety disorders for HWs from late January to early February was 46.4%, significantly higher than those in mid-term February and after late February. The pooled prevalence of depression disorders for HWs from late January to early February was 46.5%, significantly higher than those in mid-term February and after late February. HWs working in Hubei Province had a higher prevalence of anxiety and a lower prevalence of depression than those working in other regions. Nurses had a higher prevalence of anxiety and depression than other HWs.Conclusions: About one-third of HWs in China suffered anxiety, depression, and stress at the early epidemic of COVID-19. HWs in Hubei Province, especially nurses, had a higher prevalence of psychological disorders. During the pandemic, a negative psychological state may persist in a proportion of Chinese HWs, fluctuating with the control of the pandemic. The long-term impact should continue to be observed. Attention should be paid to HWs for their psychological impact due to the pandemic.Systematic Review Registration: The study protocol was registered with PROSPERO.

Early in the COVID-19 pandemic, journalists and scholars noted differences between Asians and North Americans in their support for public mask use. These differences were primarily assumed to be due d to variations in ethnocultural norms and practices. To better ascertain people’s motives for wearing masks and potential cultural differences in these rationales, this comparative, mixed-methods research examines Chinese and non-East Asian Canadians’ mask use attitudes utilizing online group interviews and a nation-wide survey Study 1, conducted in the early stages of the pandemic, captured an ambivalent, yet evolving attitude toward public mask use among the non-East Asian Canadians, which differed from their Chinese counterparts who more uniformly perceived mask use favorably. Study 2, conducted 2 months later, suggests that both groups primarily wore masks for disease protection- and prevention-related reasons. However, age and education appeared to influence the mask wearing frequency of the non-East Asian Canadians, for whom public mask use was less prevalent and normative. The attitudinal differences in public mask use call for targeted strategies to support mask wearing for different ethnocultural groups, which may be achieved partially through enhancing interethnic understanding on the diversified use of and opinions about masks. The findings suggest that favorable social norms, along with evidence-based information campaigns involving personal appeals may encourage greater mask use by the non-East Asian population.

Size perception of visual objects is highly context dependent. Here we report a novel perceptual size illusion that the self-face, being a unique and distinctive self-referential stimulus, can enlarge its perceived size. By using a size discrimination paradigm, we found that the self-face was perceived as significantly larger than the other-face of the same size. This size overestimation effect was not due to the familiarity of the self-face, since it could be still observed when the self-face was directly compared with a famous face. More crucially, such illusion effect could be extended to a new cartoon face that was transiently associated with one's own face and could also exert further contextual influences on visual size perception of other objects. These findings together highlight the role of self-awareness in visual size perception and point to a special mechanism of size perception tuned to self-referential information.

This study investigated the status quo of article retractions by Chinese researchers. The bibliometric information of 834 retractions from the Web of Science SCI-expanded database were downloaded and analysed. The results showed that the number of retractions increased in the past two decades, and misconduct such as plagiarism, fraud, and faked peer review explained approximately three quarters of the retractions. Meanwhile, a large proportion of the retractions seemed typical of deliberate fraud, which might be evidenced by retractions authored by repeat offenders of data fraud and those due to faked peer review. In addition, a majority of Chinese fraudulent authors seemed to aim their articles which contained a possible misconduct at low-impact journals, regardless of the types of misconduct. The system of scientific evaluation, the “publish or perish” pressure Chinese researchers are facing, and the relatively low costs of scientific integrity may be responsible for the scientific integrity. We suggested more integrity education and severe sanctions for the policy-makers, as well as change in the peer review system and transparent retraction notices for journal administrators.

The hundreds of millions of floating people in China who leave their hometown for a new city to improve their standard of living constitute an important phenomenon, but as yet the ethical predicaments they face, such as low compensation equity and high social exclusion, have attracted little attention. With a national sample of 125,626 floating people in China, this study investigated how and when compensation equity influences prosocial behavior through the lens of justice theory. This study found that floating people’s compensation equity positively influences prosocial behavior, and this relationship is mediated by subjective well-being. This study also supported that multilevel social exclusion, including the perception of social exclusion and provincial social exclusion strength, positively moderates the relationship between compensation equity and SWB. Moreover, the perception of social exclusion and provincial social exclusion strength moderate the mediating effect of SWB between compensation equity and prosocial behavior. Theoretical contributions and managerial implications are further discussed.

Many previous studies have documented the detrimental effects of social loafing on others (_inter_personal impacts) at the between-person level. However, social loafing may carry underappreciated _intra_personal functional effects at the within-person level. Our research develops a novel theoretical framework to investigate _when_ and _how_ engaging in social loafing enhances one’s job performance. Drawing on the effort-recovery model and moral cleansing theory, we propose that social loafing may improve subsequent job performance by enhancing recovery and guilt. Specifically, we argue that among employees who experience higher job demands or have higher moral identity, social loafing in the morning enhances their job performance in the afternoon by facilitating recovery or guilt in the morning. Two-wave daily data collected across ten consecutive workdays using the experience sampling method (ESM) supports this model. We discuss how this research identifies a functional basis for social loafing and provides implications for research and practice.

In view of the fact that vigorously promoting recycling has become a viable means to promote sustainable development, it is important to better understand the impact of recycling efforts on subsequent resource saving behavior. This research empirically examines the effects of recycling efforts on subsequent resource saving by analyzing the survey data of 356 college students in China. The recycling efforts, environmental self-identity and feeling of pride were measured using existing scales while saving behaviors and recycling cost were measured by developing new scales. Partial least squares structural equation modeling was performed to test the structural relationships among recycling efforts, environmental self-identity, feeling of pride, and saving behaviors. Further, the moderation role of recycling cost was tested. The results showed that saving behaviors could be classified into two types based on their costliness; recycling efforts have a positive effect on costless saving behaviors, while having a negative effect on costly saving behaviors; both the positive and negative effect of recycling efforts on resource saving is mediated by pride feeling and environmental self-identity; and recycling cost negatively moderates the effects of recycling efforts on pride feeling. We discuss the theoretical and managerial implications of the findings.

Individuals' knowledge hiding behavior may lead to massive economic losses to organizations, and exploring the antecedents of it has crucial relevance for mitigating its negative influences. This research aims to investigate the impact of perceived overqualification on knowledge hiding by testing the mediating effect of psychological capital and the moderating effect of person-organization fit. Empirical analyses were conducted on 249 employee dataset using versions SPSS 26 and AMOS 26. Results illustrate an inverse correlation between perceived overqualification and knowledge hiding behavior which is partly mediated by psychological capital and moderated by person-organization fit, implying that good organizational atmosphere that builds up individual psychological capital with better person-organization fit will allow employees to work positively to reduce knowledge hiding behavior when perceived overqualified. This study complements a small quantity of discussions on the positive impact of perceived overqualification on knowledge management and fills omissions in previous studies on the negative effect of perceived overqualification on knowledge hiding behavior in changing surroundings.

Metaphor has been a feature of poetry for centuries. Some metaphorical phenomena in poetry raise questions for the traditional framework, in which metaphor is a matter of the metaphorical use of individual words. White does not adopt the traditional view. He intro­duces a sentence-approach instead. I argue that the alleged phenomena occur in the Chinese poetry as well. I argue further, that White’s structure of representing metaphor can be used to analyze metaphor in the Chinese poetry, but that it must be constructed on the basis of working out the relevant cultural implicatures. In effect, interpreting a metaphor involves generating the cultural implicature where a literary quotation is being alluded to, because the quotation acts as the key to understanding the metaphor in the poetry.

Although activated spinal cord glia contribute importantly to neuropathic pain, how nerve injury activates glia remains controversial. It has recently been proposed, on the basis of genetic approaches, that toll-like receptor 4 may be a key receptor for initiating microglial activation following L5 spinal nerve injury. The present studies extend this idea pharmacologically by showing that TLR4 is key for maintaining neuropathic pain following sciatic nerve chronic constriction injury. Established neuropathic pain was reversed by intrathecally delivered TLR4 receptor antagonists derived from lipopolysaccharide. Additionally, -naltrexone, -naloxone, and -naloxone, which we show here to be TLR4 antagonists in vitro on both stably transfected HEK293-TLR4 and microglial cell lines, suppressed neuropathic pain with complete reversal upon chronic infusion. Immunohistochemical analyses of spinal cords following chronic infusion revealed suppression of CCI-induced microglial activation by -naloxone and -naloxone, paralleling reversal of neuropathic pain. Together, these CCI data support the conclusion that neuron-to-glia signaling through TLR4 is important not only for initiating neuropathic pain, as suggested previously, but also for maintaining established neuropathic pain. Furthermore, these studies suggest that the novel TLR4 antagonists -naloxone and -naloxone can each fully reverse established neuropathic pain upon multi-day administration. This finding with -naloxone is of potential clinical relevance. This is because -naloxone is an antagonist that is inactive at the -opioid selective receptors on neurons that produce analgesia. Thus, these data suggest that -opioid antagonists such as -naloxone may be useful clinically to suppress glial activation, yet -opioid agonists suppress pain.

Rapid and precise air operation mission planning is a key technology in unmanned aerial vehicles autonomous combat in battles. In this paper, an end-to-end UAV intelligent mission planning method based on deep reinforcement learning is proposed to solve the shortcomings of the traditional intelligent optimization algorithm, such as relying on simple, static, low-dimensional scenarios, and poor scalability. Specifically, the suppression of enemy air defense mission planning is described as a sequential decision-making problem and formalized as a Markov decision process. Then, the SEAD intelligent planning model based on the proximal policy optimization algorithm is established and a general intelligent planning architecture is proposed. Furthermore, three policy training tricks, i.e., domain randomization, maximizing policy entropy, and underlying network parameter sharing, are introduced to improve the learning performance and generalizability of PPO. Experiments results show that the model in this work is efficient and stable, and can be adapted to the unknown continuous high-dimensional environment. It can be concluded that the UAV intelligent mission planning model based on DRL has powerful intelligent planning performance, and provides a new idea for researching UAV autonomy.

Teachers’ emotions may be affected by structural reforms of education that emphasizes performance-based accountability and by individual psychological processes like thinking style, but there is a lack of research concerning the relationship between the three factors. In this study, thus, we attempted to test the influence of PBA on teacher emotions and to examine whether the relationship was moderated by a zhongyong thinking style in a Chinese context. A sample of 402 primary and secondary schoolteachers from Hubei, Liaoning, and Beijing in China participated in this study. Structural equation modeling was applied to develop moderation models. The results demonstrated that PBA is a singificant factor with respect to teachers’ joy, sadness/frustration, anger, and fear, as related to their job of teaching, but not love of their profession. Moreover, the ZYT style may moderate the relationship between PBA and joy.
