This study aimed to investigate the relationship between mental health literacy(MHL)and workplace well-being(WWB)of Chinese grassroots civil servants,with regulatory emotional self-efficacy(RESE)and resilience as mediating variables.A questionnaire survey was conducted among Chinese grassroots civil servants,with a valid sample size of 2673 after excluding missing values and conducting relevant data processing.The PROCESS was used to examine the relationship between MHL,RESE,resilience,and WWB.The study found that MHL among grassroots civil servants was positively and significantly correlated with WWB(r=0.73,p<0.01).RESE partially mediated the relationship between MHL and WWB(β=0.25,95%CI[0.22,0.28]).Resilience partially mediated the relationship between MHL and WWB(β=0.22,95%CI[0.19,0.26]).MHL had a positive effect on WWB through the chain mediating effect of RESE and resilience(β=0.05,95%CI[0.03,0.07]).There is a close relationship between MHL and WWB,where Chinese grassroots civil servants with higher levels of MHL can develop stronger RESE and resilience,leading to higher WWB.The results of this study remind organizational institutions of Chinese grassroots civil servants that enhancing MHL,RESE,and resilience is an important pathway to promoting their WWB. 展开更多

In this editorial,we comment on the article by Marano et al recently published in the World Journal of Gastroenterology 2023;29(45):5945-5952.We focus on the role of gut microbiota(GM)in women’s health,highlighting the need to thoroughly comprehend the sex differences in microbiota.Together,the host and GM support the host’s health.The microbiota components consist of viruses,bacteria,fungi,and archaea.This complex is an essential part of the host and is involved in neu-rological development,metabolic control,immune system dynamics,and host dynamic homeostasis.It has been shown that differences in the GM of males and females can contribute to chronic diseases,such as gastrointestinal,metabolic,neurological,cardiovascular,and respiratory illnesses.These differences can also result in some sex-specific changes in immunity.Every day,research on GM reveals new and more expansive frontiers,offering a wealth of innovative oppor-tunities for preventive and precision medicine. 展开更多

It is common to observe the epidemic risk perception(ERP)and a decline in subjective well-being(SWB)in the context of public health events,such as Corona Virus Disease 2019(COVID-19).However,there have been few studies exploring the impact of individuals’ERP within living space on their SWB,especially from a geographical and daily activity perspective after the resumption of work and other activities following a wave of the pandemic.In this paper,we conducted a study with 789 participants in urban China,measuring their ERP within living space and examining its influence on their SWB using path analysis.The results indicated that individuals’ERP within their living space had a significant negative effect on their SWB.The density of certain types of facilities within their living space,such as bus stops,subway stations,restaurants,fast food shops,convenience shops,hospitals,and public toilets,had a significantly negative impact on their SWB,mediated by their ERP within living space.Additionally,participation in out-of-home work and other activities not only increased individuals’ERP within living space,but also strengthened its negative effect on their SWB. 展开更多

Contingent self-esteem captures the fragile nature of self-esteem and is often regarded as suboptimal to psychological functioning.Self-compassion is another important self-related concept assumed to promote mental health and well-being.However,research on the relation of self-compassion to contingent self-esteem is lacking.Two studies were conducted to explore the role of selfcompassion,either as a personal characteristic or an induced mindset,in influencing the effects of contingent self-esteem on well-being.Study 1 recruited 256 Chinese college students(30.4%male,mean age=21.72 years)who filled out measures of contingent self-esteem,self-compassion,and well-being.The results found that self-compassion moderated the effect of contingent self-esteem on well-being.In Study 2,a sample of 90 Chinese college students(34%male,mean age=18.39 years)were randomly assigned to either a control or self-compassion group.They completed baseline trait measures of contingent self-esteem,self-compassion,and self-esteem.Then,they were led to have a 12-min break(control group)or listen to a 12-min self-compassion audio(self-compassion group),followed by a social stress task and outcome measures.The results demonstrated the effectiveness of the brief self-compassion training and its moderating role in influencing the effects of contingent self-esteem on negative affects after the social stress task.This research provides implications that to equip with a self-compassionate mindset could lower the risk of the impairment of well-being associated with elements of contingent selfesteem,which involves a fragile sense of self-worth.It may also provide insights into the development of an“optimal selfesteem”and the improvement of well-being. 展开更多

Rural areas are crucial for a country’s sustainable economy.New strategies are needed to develop rural areas to improve the well-being of rural population and generate new job opportunities.This is especially important in countries where agricultural production accounts for a significant share of the gross product,such as Russia.In this study,we identified the key indicators of satisfaction and differences between rural and urban citizens based on their social,economic,and environmental backgrounds,and determined whether there are well-being disparities between rural and urban areas in the Stavropol Territory,Russia.We collected primary data through a survey based on the European Social Survey framework to investigate the potential differences between rural and urban areas.By computing the regional well-being index using principal component analysis,we found that there was no statistically significant difference in well-being between rural and urban areas.Results of key indicators showed that rural residents felt psychologically more comfortable and safer,assessed their family relationships better,and adhered more to traditions and customs.However,urban residents showed better economic and social conditions(e.g.,infrastructures,medical care,education,and Internet access).The results of this study imply that we can better understand the local needs,advantages,and unique qualities,thereby gaining insight into the effectiveness of government programs.Policy-makers and local authorities can consider targeted interventions based on the findings of this study and strive to enhance the well-being of both urban and rural residents. 展开更多

The goal of village governance is to improve the well-being of farmers,so this study aims to measure the impact the quality of village governance on the well-being of farmers.It also examines the heterogeneity of this impact across different farmer groups from the perspectives of income levels and occupational differentiation.To this end,this study developed an indicator system based on survey data collected from 1,442 farmers in the Sichuan,Shaanxi,and Gansu provinces,as well as the Ningxia Hui autonomous region.Multiple linear regression models were then used to analyze this data,and the findings revealed that improvements in the quality of village governance significantly increased the well-being of farmers.Specifically,primary-level empowerment and capacity building were shown to contribute the most to the enhancement of the farmers’well-being,followed by social inclusion,and social cohesion was found to have only a minimal effect.In terms of income levels,improving the quality of village governance benefited middle-income farmers the most,followed by low-income farmers,and it had the least effect on high-income farmers.In terms of occupations,full-time farmers gained the most from improvements in the quality of village governance,followed by off-farm farmers,with part-time farmers benefiting the least.Based on these findings,this study suggests that policymakers should improve the quality of village governance to enhance the well-being of farmers,focusing on the impact that level of income and occupational differentiation have on village governance. 展开更多

The 2030 Agenda for Sustainable Development of the United Nations sets out 17 sustainable development goals(SDGs)that call for global action to end poverty,protect the planet,and improve the lives and futures of all people,including reducing inequality and taking climate action.The academic and policy issues corresponding to these two goals are income distribution and low-carbon development respectively.This paper makes a connection between the two and examines the impact of income gap on carbon intensity of well-being(CIWB)based on panel data of 40 countries around the world,which has important theoretical significance and empirical reference value.The main conclusions are as follows:(1)During the sample period,the carbon intensity of well-being of 36 in the 40 countries showed a downward trend,indicating that the pressure brought by the increase of unit well-being level on carbon emission space was gradually decreasing.The biggest drop in carbon intensity of well-being is in Estonia.(2)According to the average value of the past years,the income gaps are large in Colombia,Costa Rica,Paraguay,Ecuador and Peru,and the five countries with the smallest income gap are Ukraine,Slovenia,Belarus,the Czech Republic and Kyrgyzstan Republic.(3)The regression results of the econometric model with carbon intensity of well-being as the dependent variable,income gap as the independent variable,and urbanization rate,energy consumption structure and export trade as the control variables show that the increase of income gap will increase carbon intensity of well-being,and the increase of urbanization rate,renewable energy consumption and export dependence will reduce carbon intensity of well-being.Finally,according to the research conclusions,the policy implications for China's future high-quality development are extracted. 展开更多

This paper reviews traditional understanding of well-being from both Western and Eastern cultural perspectives. First, two distinct Western traditions in defining well-being are compared, namely hedonic and eudaemonic approaches. The hedonic approach defines happiness as the maximization of pleasure, while the eudaemonic approach regards happiness as the fulfillment of a person’s natural needs and overall flourishing. Second, the views of well-being in lens of Confucianism, Buddhism, and Taoism in the East are reviewed. The common and different understandings of well-being between Western and Eastern traditions are discussed as followed. Finally, two well-known operationalized definitions of well-being, that is subjective well-being and psychological well-being, proposed in the roots of Western traditions are elucidated. 展开更多

Purpose: During the COVID-19 pandemic, a significant number of measures were taken worldwide to limit the transmission of SARS-CoV-2, and in many ways, changed human life. All these measures had harmful consequences and impacted the well-being of many people. Children were one of the most vulnerable groups. We conducted the present study to assess children’s and staff’s well-being in French-speaking primary schools in Belgium during the COVID-19 pandemic. Methods: A 37-question questionnaire for each child based on the Revised Children’s Manifest Anxiety Scale (RCMAS), and a 14-question questionnaire for each staff based on the Hospital Anxiety and Depression (HAD) scale was undertaken in order to assess the well-being. Multiple logistic regressions were performed to assess the relationship between RCMAS or HAD and other explanatory variables. Staff reported their perception of their current life and their future life in 5 years on a Visual Analogue Scale (VAS). Results: A total of 231 children and 221 staff in 11 primary schools answered the well-being questionnaire between January and May 2021. 53% (122/231) of children had symptoms of anxiety. Girls reported more anxiety symptoms than boys (≥10: 59%;Adj OR = 2.25;95% CI [1.28;4.03]). 52% (120/231) of children had a definite state of social desirability. According to age, the youngest (6 - 7 years) children were more likely to have social desirability (≥5: 71%;Adj OR = 3.44;95% CI [1.53;8.09]) compared to the oldest (10 - 12 years). Children who did not practice outdoor/street activities were more likely to have social desirability (≥5: 60%;Adj OR = 2.59;95% CI [1.38;4.99]). In schools with a higher local incidence of SARS-CoV-2, children were more likely to have social desirability (≥5: 64%;Adj OR = 2.15;95% CI [1.13;4.17]). In schools with a lower socioeconomic status, children were more likely to have social desirability (≥5: 72%;Adj OR = 2.74;95% CI [1.23;6.37]). Higher RCMAS anxiety (r = −0.18;p −0.23;p −0.20;p Conclusion: Our results showed that the well-being of children was impacted during the COVID-19 pandemic. Special attention must be focused on the most vulnerable groups, as the consequences can be catastrophic in the long term. 展开更多

This study investigates mental health literacy among young and middle-aged urban and rural residents and the differences in mental health literacy,perceived social support and subjective well-being.From January to February 2022,620 participants(320 rural and 300 urban residents)from three provinces of China were selected by con-venience sampling.A general data questionnaire,mental health literacy scale,perceived social support scale and subjective well-being scale were administered.The mental health literacy scores of urban residents were 3.34±0.57 and those of rural residents were 2.73±0.79.The results of multiple regression analysis showed that the mental health literacy scores of rural residents were more significant than those of urban residents in terms of sex and age,while urban residents’mental health literacy scores were more significant than those of rural resi-dents in terms of monthly income.Mental health literacy,perceived social support and subjective well-being of young and middle-aged urban and rural residents were all positively correlated(P<0.01).While the level of mental health literacy is better among urban residents than rural residents,perceived social support plays a partial mediating role between mental health literacy and subjective well-being of both urban and rural residents,and should be the focus of researchers seeking to improve the level of well-being of residents. 展开更多

In recent decades,Haiti has been subject to man-made and natural disasters that have left its citizens vulnerable to a range of shocks.With a weak state unable to protect its populace,Haitians are exposed to some of the highest levels of poverty and violence in the Western Hemisphere.In recent years,Haitians have experienced two crises that this study analyzes:the instability and political violence of“peyi lòk”as well as the global pandemic of COVID-19.This community-based assessment explores the impact of these two crises on the mental health and psychological well-being of 38 Haitian university students in the understudied northern part of the country.Results indicate that both crises had similarities related to their psychological effects on young people,most notably in terms of traumatic experiences related to threats or violence,forced confinement,and large increases in population-wide uncertainty.Additionally,the extreme violence of“peyi lòk”and the widespread unpredictability of COVID-19 and its effects in the early days of the pandemic resulted in high levels of stress and fear.Both crises also resulted in extreme economic hardship for students,with many reporting difficulties accessing basic needs such as food and water.This study highlights how converging population-level crises in“complex emergencies”can heighten trauma and compromise mental health. 展开更多

Wireless Sensor Network(WSN)is a cornerstone of Internet of Things(IoT)and has rich application scenarios.In this work,we consider a heterogeneous WSN whose sensor nodes have a diversity in their Residual Energy(RE).In this work,to protect the sensor nodes with low RE,we investigate dynamic working modes for sensor nodes which are determined by their RE and an introduced energy threshold.Besides,we employ an Unmanned Aerial Vehicle(UAV)to collect the stored data from the heterogeneous WSN.We aim to jointly optimize the cluster head selection,energy threshold and sensor nodes’working mode to minimize the weighted sum of energy con-sumption from the WSN and UAV,subject to the data collection rate constraint.To this end,we propose an efficient search method to search for an optimal energy threshold,and develop a penalty-based successive convex approximation algorithm to select the cluster heads.Then we present a low-complexity iterative approach to solve the joint optimization problem and discuss the implementation procedure.Numerical results justify that our proposed approach is able to reduce the energy consumption of the sensor nodes with low RE significantly and also saves energy for the whole WSN. 展开更多

Heavy components of low-alloy high-strength(LAHS) steels are generally formed by multi-pass forging. It is necessary to explore the flow characteristics and hot workability of LAHS steels during the multi-pass forging process, which is beneficial to the formulation of actual processing parameters. In the study, the multi-pass hot compression experiments of a typical LAHS steel are carried out at a wide range of deformation temperatures and strain rates. It is found that the work hardening rate of the experimental material depends on deformation parameters and deformation passes, which is ascribed to the impacts of static and dynamic softening behaviors. A new model is established to describe the flow characteristics at various deformation passes. Compared to the classical Arrhenius model and modified Zerilli and Armstrong model, the newly proposed model shows higher prediction accuracy with a confidence level of 0.98565. Furthermore, the connection between power dissipation efficiency(PDE) and deformation parameters is revealed by analyzing the microstructures. The PDE cannot be utilized to reflect the efficiency of energy dissipation for microstructure evolution during the entire deformation process, but only to assess the efficiency of energy dissipation for microstructure evolution in a specific deformation parameter state.As a result, an integrated processing map is proposed to better study the hot workability of the LAHS steel, which considers the effects of instability factor(IF), PDE, and distribution and size of grains. The optimized processing parameters for the multi-pass deformation process are the deformation parameters of 1223–1318 K and 0.01–0.08 s^(-1). Complete dynamic recrystallization occurs within the optimized processing parameters with an average grain size of 18.36–42.3 μm. This study will guide the optimization of the forging process of heavy components. 展开更多

Although employers believe that encouraging and supporting physical exercise activities by purchasing fitness equipment and building sports venues can improve employees’well-being,the utilization rate is rather low.Since most of the evidence of the well-being promotion in the workplace concentrated on the perspectives of organizational factors and psychosocial factors and focused on the reduction of the negative affect of well-being,it is still an open question whether physical exercise has benefits on both negative and positive affect of well-being and who benefits more from physical exercise.Thus,the purpose of this study is to investigate the impact of physical exercise on occupational well-being(job burnout and work engagement)and examine whether effectiveness depends on personality traits.Online questionnaires were distributed.The sample included 671 participants from different enterprises in China.Results showed that the effectiveness of physical exercise was also applicable to well-being in the workplace.Physical exercise was negatively correlated with job burnout and positively correlated with work engagement.The effectiveness was different among employees with different personality traits.Contrary to our expectation,individuals with neuroticism were more likely to improve their work engagement through physical exercise.Extroversion and conscientiousness weakened the benefits of physical exercise.Therefore,differences of effectiveness among different personality traits emphasize the need for a more personalized strategy in physical exercise interventions. 展开更多

Backgrounds: Health does not only physical health, therefore, we need to study it from various viewpoints. Many Japanese female complain of a Hie or a low back pain (LBP), which they reduce their subjective well-being. We analyze. Those patients often have acupuncture therapy. In this study, we analyze the characteristics of Hie and LBP, the satisfaction level of alternative therapy and we pursue a tip to improve subjective well-being. Methods: Of 1000 women, Hie (+)/Hie (−) or LBP (+)/LBP (−), we compared their body temperature (BT) (axilla) and body mass index (BMI). Furthermore, the Chi test identified ten factors of “body” and seven “mind” information. Results: In the result of BT (axilla) while LBP indicated a significant difference. Both Hie and LBP showed difference in the opposite direction. Hie did now show such clear differences in “body” information. However, interestingly, all seven questions in the “mind” information showed statistical difference. Discussion and conclusion: One reason why those patients have acupuncture therapy may acupuncture therapy traditionally has not separate “mind” and “body” and it has the concept of “mind-body unity”. To improve subjective well-being, first we need to focus on “Mind” as well as “mind-body unity”. Mental-health support is important for patients with Hie or LBP to reduce physiological stress. 展开更多
