The Thesis PodcastAssociations between screen time and lower psychological well-beingDoi：10.1016/j.pmedr.2018.10.003Abstract：Previous research on associations between screen time and psychological well-being among children and adolescents has been conflicting, leading some researchers to question the limits on screen time suggested by physician organizations. We examined a large (n=40,337) national random sample of 2- to 17-year-old children and adolescents in the U.S. in 2016 that included comprehensive measures of screen time (including cellphones, computers, electronic devices, electronic games, and TV) and an array of psychological well-being measures. After 1 h/day of use, more hours of daily screen time were associated with lower psychological well-being, including less curiosity, lower self...2025-07-2319 min
The Thesis Podcast兒童和青少年的螢幕時間與較低的心理健康之間的關聯：來自一項基於人群的研究的證據論文原著：Associations between screen time and lower psychological well-being among children and adolescents: Evidence from a population-based studyDoi：10.1016/j.pmedr.2018.10.003中文摘要：先前關於兒童與青少年螢幕使用時間與心理健康之間關聯的研究結果相互矛盾，導致部分研究者開始質疑醫療機構對螢幕時間的限制建議。我們分析了一份來自美國、具代表性的全國隨機樣本（樣本數 n=40,337），涵蓋 2 至 17 歲的兒童與青少年，資料來自 2016 年，包含對螢幕使用（如手機、電腦、電子設備、電子遊戲及電視）的全面評估，以及一系列心理健康指標。結果發現，當每日螢幕使用時間超過 1 小時後，使用時間越長，心理健康越差，具體表現為：好奇心降低、自我控制力下降、注意力更易分散、交友困難、情緒穩定性較差、照顧難度增加，以及難以完成任務等。在 14 至 17 歲的青少年中，重度使用者（每日使用超過 7 小時）相比低度使用者（每日使用 1 小時），有超過兩倍的可能性曾被診斷為憂鬱症（相對風險 RR 2.39，95% 信賴區間 CI 1.54–3.70）、焦慮症（RR 2.26，CI 1.59–3.22）、接受心理健康專業人員治療（RR 2.22，CI 1.62–3.03），或在過去 12 個月內服用過心理或行為方面的藥物（RR 2.99，CI 1.94–4.62）。即使是中度使用（每日 4 小時），也與較低的心理健康狀況有關。而非使用者與低度使用者在心理健康方面通常沒有顯著差異。整體而言，螢幕時間與心理健康下降之間的關聯在青少年族群中比年幼兒童更為明顯。英文摘要：Previous research on associations between screen time and psychological well-being among children and adolescents has been conflicting, leading some researchers to question the limits on screen time suggested by physician organizations.

After 1h/day of use, more hours of daily screen time were associated with lower psychological well-being, including less curiosity, lower self-control, more distractibility, more difficulty making friends, less emotional stability, being more difficult to care for, and inability to finish tasks. Among 14 to 17 year olds, high users of screens (7+h/day vs. low users of 1h/day) were more than twice as likely to ever have been diagnosed with depression (RR 2.39, 95% CI 1.54, 3.70), ever diagnosed with anxiety (RR 2.26, CI 1.59, 3.22), treated by a mental health professional (RR 2.22, CI 1.62, 3.03) or have taken medication for a psychological or behavioral issue (RR 2.99, CI 1.94, 4.62) in the last 12months. Moderate use of screens (4h/day) was also associated with lower psychological well-being. Non-users and low users of screens generally did not differ in well-being.

The Thesis Podcast登山觀光論文原著：Mountaineering Tourism中文摘要：1993年5月，英國登山委員會（British Mountaineering Council）召開會議，討論高海拔觀光的未來發展。與會者關注的議題包括珠穆朗瑪峰上的登山人潮，有人引用登山家彼得・博德曼（Peter Boardman）的話，形容珠峰是「自我展現的競技場」。會議中也提到了環境與社會責任，以及規範以減少影響的必要性。在之後的幾年中，攀登珠峰的熱潮急劇上升，2012年的某一天甚至有234位登山者成功登頂。登山觀光的參與程度早已超出20年前與會者的想像。本書對登山觀光這一成長中的領域進行了全面且批判性的分析，探討其發展與管理相關的各項面向與議題。內容涵蓋了冒險的意義、以山區為主的冒險經驗、冒險體驗的傳遞，以及冒險學習與教育等主題。此外，本書也介紹了高山環境作為示範場域，並提出一般性管理框架，可作為登山觀光發展的基礎方法。透過全球各地不同的登山觀光發展案例，本書展現了多樣化且獨特的管理策略、政策與實務。由多位不同學術領域的頂尖學者撰寫，本書將有助於學生、研究人員與學者深入理解登山觀光這項快速成長的冒險旅遊形式，在全球範圍內的旅遊管理與發展特點。英文摘要：In May 1993 the British Mountaineering Council met to discuss the future of high altitude tourism.

By doing so it explores the meaning of adventure and special reference to mountain-based adventure, the delivering of adventure experience, and adventure learning and education. It further introduces examples of settings (alpine environments) where a general management framework could be applied as a baseline approach in mountaineering tourism development. Along with this general management framework, the book draws evidence from case studies derived from2025-07-0907 min

The Thesis Podcast當心後設認知懶惰：生成式人工智慧對學習動機、過程與表現的影響論文原著：Beware of metacognitive laziness: Effects of generative artificial intelligence on learning motivation, processes, and performanceDoi：10.1111/bjet.13544中文摘要：隨著科技與教育創新的持續發展，現今的學習者能從教師、同儕、教育科技，乃至近來的生成式人工智慧（如 ChatGPT）等代理者獲得多元支持。特別是，人機協作與混合智慧（Hybrid Intelligence）在學習中的應用，已成為學術界日益關注的議題。然而，「混合智慧」這一概念仍處於萌芽階段，學習者如何與 AI、人類專家與智慧學習系統建立共生關係、從中受益，仍不甚明朗。這一新興概念亦缺乏以實證研究為基礎，對其運作機制與學習後果的深入理解。為了填補這一研究空白，我們進行了一項隨機實驗研究，比較在寫作任務中接受不同代理者支持的學習者，在學習動機、自我調節學習過程與學習表現上的差異。受試者共117名大學生，分別接受 ChatGPT（即 AI 組）、與人類專家對談、使用寫作分析工具、或無額外工具等四種支持。我們收集並分析了他們的多通道學習資料、表現結果與動機指標。研究結果顯示： 1. 接受不同學習支持的學習者，在任務後的內在動機上沒有顯著差異； 2. 各組學習者在自我調節學習過程中的頻率與順序存在顯著差異； 3. 雖然 ChatGPT 組在作文分數提升上表現較佳，但其知識獲得與遷移並無顯著差異。我們的研究發現，即使動機相同，不同的學習支持仍導致學習過程差異，進而影響學習表現。值得注意的是，像 ChatGPT 這樣的 AI 技術可能促使學習者對技術過度依賴，並潛在地引發「後設認知懶惰」（metacognitive laziness）。總結而言，了解並善用不同代理者在學習中的優勢與限制，對於未來混合智慧的發展至關重要。英文摘要：With the continuous development of techno- logical and educational innovation, learners nowadays can obtain a variety of supports from agents such as teachers, peers, education technologies, and recently, generative artificial intelligence such as ChatGPT. In particular, there has been a surge of academic interest in human- AI collaboration and hybrid intelligence in learning. The concept of hybrid intelligence is still at a nascent stage, and how learners can benefit from a symbiotic relationship with various agents such as AI, human experts and intelligent learning systems is still unknown. The emerging concept of hybrid intelligence also lacks deep insights and understanding of the mechanisms and consequences of hybrid human- AI learning based on strong empirical research. In order to address this gap, we conducted a randomised experimental study and compared learners' motivations, self-regulated learning processes and learning performances on a writing task among different groups who had support from different agents, that is, ChatGPT (also referred to as the AI group), chat with a human expert, writing analytics tools, and no extra tool. A total of 117 university students were recruited, and their multi-channel learning, performance and motivation data were collected and analysed. The results revealed that: (1) learners who received different learning support showed no difference in post- task intrinsic motivation; (2) there were significant differences in the frequency and sequences of the self-regulated learning processes among groups; (3) ChatGPT group outperformed in the essay score improvement but their 2025-07-0206 min
