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.
文摘This work provides a descriptive analysis of the so-called Black American community whose practical consciousness is a result of adopting,and reacting to,both white values and discriminatory terms to constitute their practical activities and so-called cultural identity.Outside of the practices associated with these values and discriminatory terms,there is no sui generis Black American identity and community with its own form of system and social integration that is different from,or diametrically opposes,the Protestant Ethic and the spirit of capitalism of their white counterparts,which would emerge out of that relationship.
文摘This study focuses on the application of dynamic route planning and augmented reality(AR)technology within interactive theme trail platforms.Taking the“Dongpo Travelogue”digital guide mini-program as a case study,it employs empirical analysis to explore its impact on enhancing visitor engagement and cultural identification.Employing a combined quantitative and qualitative methodology,the study analyses the platform’s functional implementation in route planning,cultural narration,interactive games,and their impact on visitor experience.Findings indicate that the integration of dynamic route planning and AR technology significantly enhances visitor engagement and cultural identity,offering novel insights for the digital transformation of the cultural tourism industry.
文摘The problem of overseas Chinese identity is a hot spot in the field of overseas Chinese research in recent years.It reflects the Chinese’s cognition,emotion,and behavior of ethnic characteristics.This paper takes Chinese college students with American nationality as the research object,visiting universities in North Carolina and California as visiting scholars and doctoral students,and summarizes and analyzes the identity characteristics of contemporary Chinese American college students and puts forward corresponding suggestions through in-depth interviews with 46 Chinese American college students and 12 Chinese families.
