This study aims to investigate the impact of vulnerable narcissism on social anxiety in adolescents, specificallyfocusing on the mediating effects of self-concept clarity (SCC) and self-esteem (SE) in the relationship between vulnerablenarcissism and social anxiety. Through cluster sampling, a questionnaire survey was conducted among 982 students from threesecondary schools in two provinces. The data was analyzed using structural equation modeling (SEM). The results revealedthat there was a significant negative correlation between vulnerable narcissism and both self-concept clarity and self-esteem,while there was a significant positive correlation between vulnerable narcissism and social anxiety. Additionally, self-conceptclarity showed a significant positive correlation with self-esteem but had a negative correlation with social anxiety. Both selfconceptclarity and self-esteem played an intermediary role in the chain linking vulnerable narcissism to social anxiety. Thisstudy confirms the mediating role of both self-concept clarity and self-esteem in explaining how vulnerable narcissisminfluences social anxiety, providing valuable insights into its underlying mechanism.展开更多

文摘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.
文摘BACKGROUND Most studies have defined economic well-being as socioeconomic status,with little attention given to whether other indicators influence self-esteem.Little is known about racial/ethnic disparities in the relationship between economic wellbeing and self-esteem during adulthood.AIM To explore the impact of economic well-being on self-esteem in adulthood and differences in the association across race/ethnicity.METHODS The current study used data from the National Longitudinal Survey of Youth 1979.The final sample consisted of 2267 African Americans,1425 Hispanics,and 3678 non-Hispanic Whites.Ordinary linear regression analyses and logistic regression analyses were conducted.RESULTS African Americans and Hispanics were more likely to be in poverty in comparison with non-Hispanic Whites.More African Americans were unemployed than Whites.Those who received fringe benefits,were more satisfied with jobs,and were employed were more likely to have higher levels of self-esteem.Poverty was negatively associated with self-esteem.Interaction effects were found between African Americans and job satisfaction predicting self-esteem.CONCLUSION The role of employers is important in cultivating employees’self-esteem.Satisfactory outcomes or feelings of happiness from the workplace may be more important to non-Hispanic Whites compared to African Americans and Hispanics.

文摘Objectives:To explore the relationship between college students’self-esteem(SE)and their social phobia(SP),as well as the mediating role of fear of negative evaluation(FNE)and the moderating effect of perfectionism.Methods:A convenience sampling survey was carried out for 1020 college students from Shandong Province of China,utilizing measures of college students’self-esteem,fear of negative evaluation,perfectionism,and social phobia.Data analysis was performed using the SPSS PROCESS macro.Results:(1)college students’self-esteem significantly and negatively predicts their social phobia(β=−0.31,t=−10.10,p<0.001);(2)fear of negative evaluation partially mediates the relation between self-esteem and social phobia among college students,with the mediating effect accounting for 48.97%of the total effect(TE);(3)the mediating role of fear of negative evaluation is moderated by perfectionism(β=0.18,t=7.75,p<0.001),where higher levels of perfectionism strengthen the mediating effect of fear of negative evaluation.Conclusions:Perfectionism moderates the mediating effect that fear of negative evaluation plays,establishing a moderated mediating model.

文摘Background:To reduce adolescents’social anxiety,the study integrates external factors(social media usage)with internal factors(imaginary audience and appearance-based self-esteem)to internal mechanisms of adolescents’social anxiety in the Internet age based on objective self-awareness theory and self-esteem importance weighting model.Methods:Utilizing the Social Media Usage Intensity Scale,Social Anxiety Scale,imaginary Audience Scale,and Physical Self Questionnaire,we surveyed 400 junior high school students from three schools in Hubei province,China.Results:A significantly positive correlation is revealed between the intensity of social media usage and both social anxiety and imaginary audience(p<0.001).Conversely,social media usage intensity and appearance self-esteem are significantly negatively correlated(p<0.001).Additionally,the perception of an imaginary audience was negatively correlated with appearance self-esteem(p<0.001).Furthermore,we found that imaginary audience(indirect effect of 0.14,95%CI=[0.02,0.07])and appearance self-esteem(indirect effect of 0.14,95%CI=[0.02,0.07])can respectively act as independent mediators between social networking site use intensity and social anxiety,Additionally,the relationship between imaginary audience and appearance self-esteem can also be chain-mediated(indirect effect of 0.03,95%CI=[0.00,0.02])separately affect the relationship between the two.Conclusion:The imaginary audience serves as an independent mediator that links social media usage intensity to social anxiety among adolescents.Additionally,the observed chain mediation effect involving both the imaginary audience and appearance self-esteem provides novel insights for developing strategies aimed at addressing adolescent social anxiety.
文摘Using Euler’s first-order explicit(EE)method and the peridynamic differential operator(PDDO)to discretize the time and internal crystal-size derivatives,respectively,the Euler’s first-order explicit method–peridynamic differential operator(EE–PDDO)was obtained for solving the one-dimensional population balance equation in crystallization.Four different conditions during crystallization were studied:size-independent growth,sizedependent growth in a batch process,nucleation and size-independent growth,and nucleation and size-dependent growth in a continuous process.The high accuracy of the EE–PDDO method was confirmed by comparing it with the numerical results obtained using the second-order upwind and HR-van methods.The method is characterized by non-oscillation and high accuracy,especially in the discontinuous and sharp crystal size distribution.The stability of the EE–PDDO method,choice of weight function in the PDDO method,and optimal time step are also discussed.
文摘Fujian cuisine is a distinctive Chinese cuisine.Today,there are many faults and mistakes in the translation of the dish names,which leads to the failure and inconvenience of cross-cultural communication.The paper is an attempt to probe into the appropriate translation of Fujian dish names by the employment of explicitation.
文摘Based on corpus-related software and strategic framework of explicitation translation in applied texts,this paper uses Report on the Work of the Government as an example and explore the explicitation in political texts.According to the research results,political texts have shown explicitation in four sectors of the framework,especially the sector of first person plural pronouns,with quantity,language,culture,and others as influential factors.
文摘Objective:To investigate the relationship between social intelligence(SI),empathy,and self-esteem among nursing students.Methods:A quantitative cross-sectional design was utilized to conduct this study.Data were collected from 465 students from 4 different nursing colleges between April and November 2021.The Tromso Social Intelligence Scale(TSIS),Jefferson Empathy Scale,and Rosenberg Self-Esteem Scale were used to collect data.A complete enumerative technique was used to select the students at the time of data collection.Results:Most of the student nurses scored lower in SI.However,they had an acceptable level of empathy and a high level of selfesteem.A correlation was found between self-esteem and gender,as well as empathy and year of study.Conclusions:Our findings suggest that nursing students would benefit from improved SI skills.More work is needed to determine how best to incorporate these concepts into nursing curricula and create training programs for nursing students.
文摘This study used a descriptive-quantitative research method as it describes the profile of Chinese university professors in terms of age,gender,and educational background.It also described the leadership virtues in terms of prudence,fortitude,temperance,and justice;professional self-esteem in terms of career choice and adaptability,career satisfaction and values,career impact and fulfillment,and career competence and evaluation;and teaching management in terms of teaching management and evaluation,the area of teaching and research activities,and the area of collective lesson planning activities.Diversity leadership training and instructional management training are provided to meet the needs of different groups of faculty and staff of different gender,age,and education levels.Individualized professional development plans are based on the personal characteristics and needs of professors,particularly in the areas of leadership,teaching management,and career satisfaction.To address the relationship among leadership virtues,professional self-esteem,and teaching management,long-term,in-depth research is encouraged to better understand the dynamics between them.Based on the results,this paper recommends the implementation of the proposed professional development plan.
