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The rapid evolution of quantum computing poses significant threats to traditional cryptographic schemes,particularly in Decentralized Finance(DeFi)systems that rely on legacy mechanisms like RSA and ECDSA for digital identity verification.This paper proposes a quantum-resilient,blockchain-based identity verification framework designed to address critical challenges in privacy preservation,scalability,and post-quantum security.The proposed model integrates Post-quantum Cryptography(PQC),specifically lattice-based cryptographic primitives,with Decentralized Identifiers(DIDs)and Zero-knowledge Proofs(ZKPs)to ensure verifiability,anonymity,and resistance to quantum attacks.A dual-layer architecture is introduced,comprising an identity layer for credential generation and validation,and an application layer for DeFi protocol integration.To evaluate its performance,the framework is tested on multiple real-world DeFi platforms using metrics such as verification latency,throughput,attack resistance,energy efficiency,and quantum attack simulation.The results demonstrate that the proposed framework achieves 90%latency reduction and over 35%throughput improvement compared to traditional blockchain identity solutions.It also exhibits a high quantum resistance score(95/100),with successful secure verification under simulated quantum adversaries.The revocation mechanism—implemented using Merkle-tree-based proofs—achieves average response times under 40 ms,and the system maintains secure operations with energy consumption below 9 J per authentication cycle.Additionally,the paper presents a security and cost tradeoff analysis using ZKP schemes such as Bulletproofs and STARKs,revealing superior bits-per-byte efficiency and reduced proof sizes.Real-world adoption scenarios,including integration with six major DeFi protocols,indicate a 25%increase in verified users and a 15%improvement in Total Value Locked(TVL).The proposed solution is projected to remain secure until 2041(basic version)and 2043(advanced version),ensuring long-term sustainability and future-proofing against evolving quantum threats.This work establishes a scalable,privacy-preserving identity model that aligns with emerging post-quantum security standards for decentralized ecosystems.
文摘In the wave of internet culture,short videos have become an indispensable medium for social communication.The metaphorical hot words contained within them serve as a unique linguistic phenomenon that leads topics and focuses attention,greatly enriching the expressive layers and rhetorical charm of short videos,and significantly enhancing the video’s theme orientation and emotional identification.This research aims to explore the relationship between the use of metaphorical Internet buzzwords in short videos and the thematic and emotional orientation.The study adopts a combination of qualitative and quantitative methods,taking 10 videos with over 10,000 likes posted by a well-known blogger on Xiaohongshu in 2024 as the research object,transcribing the text,forming research corpora,and conducting multi-dimensional cognitive analysis on them.The study shows that about half of short videos contain metaphorical hot words.Different types of metaphorical hot words can trigger different emotional reactions from fans,especially humorous metaphorical hot words that can stimulate fans’emotional identification and resonance.In addition,in terms of fan participation,videos using metaphorical hot words tend to attract more fan attention than those that do not:these videos not only attract more fans to watch and like,but also trigger more comments and sharing behaviors.In summary,short videos cleverly use metaphors to create internet hot words,significantly enhancing the video’s thematic guidance and emotional resonance,manifested in creating popular topics,clarifying guiding themes,enhancing content attractiveness,and stimulating strong emotional identification,thereby promoting interactive behaviors such as likes and shares.These findings provide a reference for research in related fields such as metaphor,communication studies,and sociology.
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As universities in Kazakhstan continue to address the challenges that come with developing English-medium instruction(EMI)programs,university Science,Technology,Engineering,and Mathematics(STEM)teachers need to develop capacities to teach in English,while their English teacher counterparts need to develop content-specific pedagogical knowledge.Content and Language Integrated Learning(CLIL)pedagogies,defined as the integration of both language and content curricular goals,have emerged as a vehicle to facilitate this development for both types of teachers.However,what it means to be a CLIL teacher may vary considerably as teachers leverage their professional knowledge and personal experiences.We,therefore,explore teachers’conceptions of CLIL and how their disciplinary,linguistic,and pedagogical backgrounds enable or burden them to forge a“CLIL teacher”identity.This qualitative study illustrates the salient points of the journeys taken by two university teachers,one a specialist in oil and gas,the other an English teacher and teacher educator.Drawing on extended one-on-one interviews,we present two teachers’experiences through a series of CLIL-informed workshops.Using a multidisciplinary analytical framework,we map the ways in which the two teacher participants negotiate their identities in relation to CLIL.The findings highlight the importance of understanding teacher experiences,particularly their language learning backgrounds,attitudes toward supporting student learning,and relationships with their colleagues as they work to adapt to teaching English and STEM subjects in university EMI contexts.
文摘Teacher professional identity is a comprehensive reflection of teachers’role perception,emotional experiences,and behavioral tendencies towards their profession.It serves as an intrinsic driving force for teachers’professional development and is also a crucial issue in teacher education research.From a global perspective,this study systematically reviews and examines relevant research on the professional identity of international Chinese language teachers(ICLTs).A comparative analysis is conducted between Chinese and foreign scholars’research in terms of theoretical foundations,research subjects,research content,and research methodologies.This comprehensive overview of the current research landscape in this field,along with a summary of existing achievements and identified problems,facilitates the transformation of fragmented research findings on ICLTs’professional identity into a systematic understanding and reveals research gaps.Building upon this foundation,the study proposes future research prospects for the professional identity of ICLTs from aspects such as the construction of a cross-cultural perspective-based teacher professional identity system,the transformation of teacher professional identity in the context of digital transformation,and case studies on ICLTs’professional identity.The aim is to promote high-quality development in both theory and practice of international Chinese language education.

文摘Attention deficit hyperactivity disorder(ADHD)turns into a common neuro progressional disorder.Although gender identity has obtained increasing attention in ADHD researches,its role in ADHD presentation and treatment response remains underexplored.Our review seeks to mainly delve into the effect of gender identity on ADHD,exploring the unique needs of individuals with various gender identities in the context of ADHD symptoms,diagnostic assessment,and treatment,with the goal of supplying theoretical support and practical recommendations for future research and clinical practice.The primary content includes,specifically:(1)Symptom expression differences:Gender identity significantly affects ADHD symptoms;male-identified individuals commonly perform worse in task orientation and attention stability,while female-identified individuals may demonstrate more variability in attention control and executive functions;(2)Diagnosis and treatment:Clinical practice generally neglects the impact of gender identity on ADHD management,with personalized needs of gender-identified individuals frequently not adequately addressed,potentially,affecting treatment outcomes;and(3)Future research directions:Future studies should further assess how gender identity affects the specific mechanisms of ADHD,conduct researches in multicultural contexts,and engage in long-term follow-up studies to evaluate the long-term impact of gender identity on ADHD progression.Besides,enhanced funding and public education on the relationship between gender identity and ADHD are needed to advance the field.
文摘This study examines how generative artificial intelligence(AI)reshapes creative identity in design education.Drawing on post-humanist and network-based theories,it frames AI as a cognitive collaborator in ideation and authorship.Mixed-methods data reveal student anxiety and stylistic confusion,contrasted with designers’adaptive strategies.The AI–Cognition–Identity framework supports curricula that promote reflective,ethical,and epistemically informed AI-integrated pedagogy.
文摘Grazia Deledda’s literary works explore the deep ties between Sardinian culture,community traditions,and the politics of food.Through vivid food imagery,she sheds light on how meals and eating habits reflect social hierarchies,cultural identity,and power dynamics.By carefully incorporating culinary elements into narrative contexts,she shed light on the fundamental role that food plays in constructing both individual and collective identities.Her portrayals of shared meals,ceremonial feasts,and periods of scarcity function as pointed critiques of the socio-political circumstances of her era,demonstrating the intricate connections between food distribution,consumption patterns,and prevailing power structures(Heyer-Caput,2008,pp.142-47;King,1999,pp.xv-xxii).These narratives simultaneously preserve cultural heritage while exposing deep-seated social inequities,positioning food as both an instrument of cultural continuity and social criticism.Furthermore,Deledda addresses the inherent tensions between established food traditions and emerging regulatory systems,particularly highlighting how agricultural policies profoundly affect local communities(Kozma,2002,pp.87-93;Parasecoli,2019,p.120).This investigation reveals how Deledda’s literary contributions engage meaningfully with contemporary debates surrounding food sovereignty and the broader socio-political implications of food policy implementation.Through careful analysis of these thematic elements,her works provide essential insights into the ways culinary practices reflect wider cultural and political tensions,compelling readers to reassess food’s persistent influence in constructing social realities and collective identity.
