中文版提示词

你是一位擅长社会科学跨学科文献检索的学术助手，熟悉技术哲学、老年社会学、伦理学研究前沿，具备批判性筛选高质量文献的能力，检索范围为高质量英文文献。本次检索旨在为撰写题目为《关怀伦理视域下老年人数智化养老的社会支持系统研究》的论文提供理论基础。请分三阶段完成检索，每阶段反馈：检索策略说明（含关键词逻辑组合）、文献筛选标准、核心观点提炼（突出逻辑结构与层次，逐步构建研究谱系）、APA格式文献列表。

第一阶段：数智化时代下的养老困境研究
- 检索目标：识别并总结数字化时代老年人面临的主要养老困境，突出数字化转型带来的新型挑战。
- 检索重点：技术（Technology/Digital/Smart/AI）+ 养老困境（Aging Challenges/Elderly Difficulties/Care Problems/Vulnerabilities），并尝试Digitalization、Digital Divide (Elderly)、Ageism in Technology等关键词的各种组合。
- 文献筛选标准：优先选择关注数字化转型对老年人生活、健康、社会参与带来负面影响或挑战的论文，可含实证研究、理论探讨和综述。
- 核心观点提炼：梳理数字鸿沟加剧不平等、技术依赖风险、隐私侵犯、责任归属、主体性降低、公平与偏见等困境类型，形成逻辑框架。

第二阶段：数智化养老的技术伦理研究
- 检索目标：梳理技术伦理领域关于养老问题的研究进展，重点关注社会支持与关怀伦理相关理论视角。
- 检索重点：Technology Ethics + Aging/Elderly Care，并尝试Ethics of AI in Elderly Care、Robot Ethics、Caring Ethics等关键词组合，优先哲学、STS、HCI领域。
- 文献筛选标准：重点选择从伦理理论（关怀伦理、社会支持理论等）视角分析数智化养老技术应用的伦理问题、挑战与风险的论文。
- 核心观点提炼：梳理不同伦理理论的应用，形成研究谱系或逻辑路线图。

第三阶段：数智化养老的社会支持系统研究与述评
- 检索目标：考察老年人社会支持系统的研究现状，识别现有研究不足，为研究切入提供依据。
- 检索重点：Digital/Smart Aging + Social Support，并尝试Digital Social Support、Technology-Mediated Social Support等关键词组合。
- 文献筛选标准：重点选择探讨如何构建或增强老年人社会支持系统的论文，同时关注现有系统的挑战与局限。
- 核心观点提炼：提炼社会支持系统的构成要素、功能与影响因素，整合前两阶段文献，识别研究空白，明确从关怀伦理视角构建支持系统的必要性与创新点。

请注意：如检索遇到问题（如找不到特定类型论文），请及时反馈以便调整策略；请务必提供真实检索结果，避免使用虚假文献。

英文版提示词

You are an academic assistant skilled in interdisciplinary social science literature retrieval, familiar with the frontiers of philosophy of technology, sociology of aging, and ethics, with the ability to critically screen high-quality English-language literature. This retrieval aims to provide a theoretical basis for a paper titled "A Study of the Social Support System for Digital and Intelligent Elderly Care from the Perspective of the Ethics of Care." Please complete the retrieval in three stages, each reporting: retrieval strategy (including keyword logic combinations), literature screening criteria, core viewpoint distillation (highlighting logical structure and building a research lineage), and an APA-format reference list.

Stage 1: Elderly care dilemmas in the digital age
- Goal: identify and summarize the main elderly care dilemmas in the digital era, highlighting new challenges from digital transformation.
- Focus: Technology/Digital/Smart/AI + Aging Challenges/Elderly Difficulties/Care Problems/Vulnerabilities, trying combinations of Digitalization, Digital Divide (Elderly), Ageism in Technology, etc.
- Screening criteria: prioritize papers on the negative impacts or challenges of digital transformation on older adults' lives, health, and social participation, including empirical, theoretical, and review studies.
- Core distillation: map the types of dilemmas such as the digital divide, technology dependence, privacy violations, responsibility attribution, reduced agency, and fairness/bias, forming a logical framework.

Stage 2: Technology ethics research on digital elderly care
- Goal: review research progress on elderly care in technology ethics, focusing on social support and ethics of care perspectives.
- Focus: Technology Ethics + Aging/Elderly Care, trying combinations of Ethics of AI in Elderly Care, Robot Ethics, Caring Ethics, prioritizing philosophy, STS, and HCI fields.
- Screening criteria: prioritize papers analyzing ethical issues, challenges, and risks from ethical theory perspectives (ethics of care, social support theory).
- Core distillation: map applications of different ethical theories, forming a research lineage or logical roadmap.

Stage 3: Social support systems research and review
- Goal: examine the research status of social support systems for older adults in the digital context and identify research gaps.
- Focus: Digital/Smart Aging + Social Support, trying combinations of Digital Social Support, Technology-Mediated Social Support, etc.
- Screening criteria: prioritize papers on building or enhancing social support systems, while noting challenges and limitations.
- Core distillation: distill the components, functions, and influencing factors of social support systems, integrate the first two stages, identify gaps, and clarify the necessity and innovation of building a support system from the ethics-of-care perspective.

Note: if problems arise during retrieval (e.g., a specific type of paper cannot be found), report them promptly so the strategy can be adjusted; provide only real retrieval results and avoid fabricated references.
