文摘Background:Emerging adulthood is a critical period for ego identity exploration and consolidation,and self-presentation on social media constitutes a salient online context for this developmental process.However,limited research has explored the associations between self-presentation on WeChat Moments and ego identity.This study aims to examine these associations,focusing on the mediating role of online positive feedback and the moderating role of gender.Methods:Using a three-wave longitudinal design,this study followed 767 Chinese college students(Mean age=18.96 years)through cluster sampling.Participants completed self-report questionnaires assessing self-presentation on WeChat Moments,online positive feedback,and ego identity status.Data analyses were conducted using mediation modeling and multi-group structural equation modeling.Results:Authentic self-presentation was positively associated with identity achievement and negatively associated with identity diffusion,whereas positive self-presentation was linked to higher levels of identity foreclosure.Online positive feedback played a significant mediating role in the associations between self-presentation strategies and identity statuses,and gender differences were observed in this mediating pathway.For both males and females,authentic self-presentation was associated with higher identity achievement through online positive feedback.However,indirect associations with identity foreclosure and diffusion were observed only among females:authentic self-presentation was linked to lower levels,whereas positive self-presentation was linked to higher levels of foreclosure and diffusion through online positive feedback.No comparable indirect associations were detected among males.Conclusions:Online positive feedback is closely linked to self-presentation strategies and ego identity statuses,with these associations varying by gender.

文摘Objective:To analyze the related factors affecting the professional identity of nursing students before and after clinical practice,hoping to provide reference for the career development and education of nursing students.Methods:A total of 393 undergraduate nursing students of grade 2020 from the Department of Nursing of a university in Shanxi Province were selected.The professional choice motivation,educational attainment expectation,future career planning,professional practice,and employment prospect expectation of nursing students before clinical practice,and the willingness to upgrade educational attainment,professional experience,career development expectation,and employment planning of nursing students after clinical practice were investigated.Through statistical analysis of the survey data,the related influencing factors affecting the professional identity of nursing students before and after clinical practice were explored.Results:The observation of general data showed that the proportion of female students in the survey sample was higher than that of male students,and the proportion of those whose family residence was in rural areas was slightly higher than that in urban areas.The analysis of students’own situation showed that nursing students chose the nursing major because of the high expected employment rate,but they were generally anxious about the employment prospect before the internship,showing a contradictory mentality.The analysis of students’professional ability showed that nursing students believed that their professional ability was mainly reflected in the vocational adaptability.The analysis of the social environment showed that the educational attainment expectations of nursing students were mainly undergraduate and master’s degrees,and they preferred to engage in clinical nursing work rather than nursing research.The analysis on the selection of internship hospitals shows that nursing students’choice of internship hospitals is mainly influenced by the duration of the internship,and they consider the correlation between the selection of internship hospitals and future employment decisions to be low.The analysis on the surrounding environment such as family and school shows that the professional identity of nursing students is mainly influenced by the opinions of school teachers and parents,but the occupations of most of the family members of nursing students are not related to medicine.Conclusion:Targeted intervention strategies should be formulated based on the relevant influencing factors that affect the professional identity of nursing students before and after clinical internship,to enhance the professional identity and employment confidence of nursing students,and promote the healthy and sustainable development of nursing education and the medical service industry.
文摘This study focuses on Chinese social media platforms(Weibo and Douyin),adopting a mixed-methods approach combining quantitative and qualitative research to explore patterns of code-switching in online language and its role in identity negotiation among internet users.Quantitative analysis of 208 valid questionnaires and subsequent qualitative discourse analysis reveal that 83%of users unconsciously engage in Chinese-English code-switching,primarily demonstrating intra-sentential switching patterns where English words embed as salient“figures”against the Chinese“ground.”Results of the Chi-square test indicate significant correlations between code-switching frequency,types,and users’identity dimensions(p<0.05).Data identified three identity functions:cultural belonging,in-group signaling,and persona curation.The study confirms that code-switching in digital contexts has transcended the level of linguistic efficiency to become an important social infrastructure for internet users to construct their identities.
文摘The integration of artificial intelligence(AI)with advanced power technologies is transforming energy system management,particularly through real-time data monitoring and intelligent decision-making driven by Artificial Intelligence Generated Content(AIGC).However,the openness of power system channels and the resource-constrained nature of power sensors have led to new challenges for the secure transmission of power data and decision instructions.Although traditional public key cryptographic primitives can offer high security,the substantial key management and computational overhead associated with these primitives make them unsuitable for power systems.To ensure the real-time and security of power data and command transmission,we propose a lightweight identity authentication scheme tailored for power AIGC systems.The scheme utilizes lightweight symmetric encryption algorithms,minimizing the resource overhead on power sensors.Additionally,it incorporates a dynamic credential update mechanism,which can realize the rotation and update of temporary credentials to ensure anonymity and security.We rigorously validate the security of the scheme using the Real-or-Random(ROR)model and AVISPA simulation,and the results show that our scheme can resist various active and passive attacks.Finally,performance comparisons and NS3 simulation results demonstrate that our proposed scheme offers enhanced security features with lower overhead,making it more suitable for power AIGC systems compared to existing solutions.

文摘This study investigates community identity in Nanjing’s historic Hehuatang community during urban renewal,revealing tensions between heritage preservation and modernization.Through ethnographic research,three key factors are identified shaping identity:(i)material conditions including series of spatial conflicts around overcrowding,(ii)social tensions such as tenant-aborigine divides and generational misunderstanding,and(iii)institutional governance as top-down policies would exacerbate distrust.Despite 82%of residents expressing place attachment,67%desire relocation due to deteriorating liveability—a paradox highlighting the failure of China’s contemporary performative participation models.The adapted three-layer creativity model underscores the need to reconcile physical renewal with social equity.Findings advocate for co-design processes that integrate resident agency,offering lessons for sustainable urban renewal in rapidly developing contexts.

文摘Objective:To examine how emotional labor demands and strategies influence work engagement and occupational identity among Portuguese volunteer firefighters.Methods:Participants completed the Emotional Work Requirements Scale,Emotional Labour Scale,Utrecht Work Engagement Scale,and Social Identity Scale.Multiple linear regression analyses were conducted to assess the predictive effects of emotional labor demands and strategies on work engagement and occupational identity.Results:Emotional labor explained 11.8%of the variance in work engagement and 10.9%in occupational identity.Positive emotion expression significantly predicted higher work engagement and a stronger occupational identity,while the suppression of negative emotions predicted a weaker occupational identity.Other emotional labor dimensions were not significant.Conclusions:Findings underscore the dual role of emotional labor—as a resource when positive emotions are expressed and as a strain when negative emotions are habitually suppressed.Targeted interventions to promote authentic positive expression and effective emotional processing may enhance firefighters’well-being,strengthen crisis team performance,and benefit the communities they serve.Further research is needed to deepen the understanding of emotional labor in crisis response contexts.
文摘BACKGROUND Global tumor incidence rises and therapies advance,driving oncology nursing specialization.Granting nurses prescriptive authority optimizes care but polarizes nurses'attitudes due to factors like risk and competence,hindering policy implementation.AIM To investigate the current status of the attitudes of oncology specialist nurses toward having prescribing authority,specifically concerning symptom management and supportive care in oncology practice,and we conducted a path analysis of their influencing factors.METHODS As participants in the survey,oncology specialist nurses working in hospitals of different grades in Jiangsu Province were selected from March 2025 to May 2025 using a stratified sampling method.The questionnaires were administered using the general information questionnaire,the beliefs and attitudes about nurses'prescriptive authority scale,the nurses'professional identity scale,and the selfefficacy scale.Pearson’s method was used to analyze the correlation between beliefs and attitudes about the prescriptive authority,professional identity,and self-efficacy of nurses.Multiple linear regression was performed to analyze the factors influencing the beliefs and attitudes of nurses’prescriptive authority.The Amos plug-in was used to construct structural equation models to analyze the influencing pathways.RESULTS A total of 329 questionnaires were distributed,and 328 valid questionnaires were returned(effective recovery rate:99.70%).The total score of the 328 oncology nurses on the beliefs and attitudes about nurses'prescriptive authority scale was 101.88±15.13,indicating a moderately high level.Univariate analysis revealed that gender and hospital grade were associated with this score(P<0.05).The Pearson correlation analysis revealed that self-efficacy was positively correlated with the scores of the beliefs and attitudes about nurses’prescriptive authority scale and the nurses’professional identity scale(r=0.4999,P<0.0001 and r=0.7048,P<0.05,respectively),whereas occupational identity was positively correlated only with the former(r=0.6209,P<0.05).Multiple linear regression analysis revealed occupational identity and self-efficacy as the factors influencing the scores of the beliefs and attitudes about nurses’prescriptive authority scale(P<0.05).The results of the path analysis revealed that selfefficacy significantly positively affected nurses’occupational identity and their beliefs and attitudes about having prescriptive authority;occupational identity played a mediating role between the two,with a mediating effect accounting for 54.46% of the total effect,and the structural equation model was well-fitted.CONCLUSION Oncology nurses have more positive attitudes toward prescriptive authority.In addition,self-efficacy positively and indirectly affects nurses’attitudes toward prescriptive authority through the mediating effect of occupational identity.This can be used as a basis for clinical practice to take targeted measures to improve nurses’self-efficacy and occupational identity,thus creating favorable conditions for effectively implementing the policy of prescriptive authority.
文摘This study examines the intersection of emotional trust and cultural identity in artificial intelligence(AI)-generated content,focusing on Chinese Australians.It explores how emotional trust-confidence in the authenticity and intent of AI-created stories-affects their engagement,and the role of cultural identity in shaping these perceptions.Using a qualitative case study approach with semi-structured interviews and analysis of AI materials,the research finds that culturally authentic and emotionally resonant narratives foster higher trust,while misrepresentations cause disengagement.The paper emphasizes the need for cultural nuance and community engagement in AI content creation to support positive identity formation,offering recommendations for emotionally authentic and culturally sensitive digital storytelling.
