Metal tellurides(MTes) are highly attractive as promising anodes for high-performance potassium-ion batteries. The capacity attenuation of most reported MTe anodes is attributed to their poor electrical conductivity and large volume variation. The evolution mechanisms, dissolution properties, and corresponding manipulation strategies of intermediates(K-polytellurides, K-pTe_(x)) are rarely mentioned. Herein,we propose a novel structural engineering strategy to confine ultrafine CoTe_(2) nanodots in hierarchical nanogrid-in-nanofiber carbon substrates(CoTe_(2)@NC@NSPCNFs) for smooth immobilization of K-pTe_(x) and highly reversible conversion of CoTe_(2) by manipulating the intense electrochemical reaction process. Various in situ/ex situ techniques and density functional theory calculations have been performed to clarify the formation, transformation, and dissolution of K-pTe_(x)(K_(5)Te_(3) and K_(2)Te), as well as verifying the robust physical barrier and the strong chemisorption of K_(5)Te_(3) and K_(2)Te on S, N co-doped dual-type carbon substrates. Additionally, the hierarchical nanogrid-in-nanofiber nanostructure increases the chemical anchoring sites for K-pTe_(x), provides sufficient volume buffer space, and constructs highly interconnected conductive microcircuits, further propelling the battery reaction to new heights(3500 cycles at 2.0 A g^(-1)). Furthermore, the full cells further demonstrate the potential for practical applications. This work provides new insights into manipulating K-pTe_(x) in the design of ultralong-cycling MTe anodes for advanced PIBs.

Objective: Plant-based diets have multiple health benefits for cancers;however, little is known about the association between plant-based dietary patterns and esophageal cancer(EC).This study presents an investigation of the prospective associations among three predefined indices of plant-based dietary patterns and the risk of ***: We performed endoscopic screening for 15,709 participants aged 40-69 years from two high-risk areas of China from January 2005 to December 2009 and followed the cohort until December 31, 2022. The overall plant-based diet index(PDI), healthful plant-based diet index(h PDI), and unhealthful plant-based diet index(u PDI), were calculated using survey responses to assess dietary patterns. We applied Cox proportional hazard regression to estimate the multivariable hazard ratios(HRs) and 95% confidence intervals(95% CIs) of EC across 3plant-based diet indices and further stratified the analysis by ***: The final study sample included 15,184 participants in the cohort. During a follow-up of 219,365person-years, 176 patients with EC were identified. When the highest quartile was compared with the lowest quartile, the pooled multivariable-adjusted HR of EC was 0.50(95% CI, 0.32-0.77) for h PDI. In addition, the HR per 10-point increase in the h PDI score was 0.42(95% CI, 0.27-0.66) for ECs. Conversely, u PDI was positively associated with the risk of EC, and the HR was 1.80(95% CI, 1.16-2.82). The HR per 10-point increase in the u PDI score was 1.90(95% CI, 1.26-2.88) for ECs. The associations between these scores and the risk of EC were consistent in most subgroups. These results remained robust in sensitivity ***: A healthy plant-based dietary pattern was associated with a reduced risk of EC. Emphasizing the healthiness and quality of plant-based diets may be important for preventing the development of EC.

本文是《问物——可触摸的意义》一书的序言,主题表达作者对其作品的思路与方法的反思。作者认为,物不仅是物理事实,同是也是展现人类精神意义的有质感的存在。在回顾关于心-理意义结构思路形成的基础上,序文尝试揭示某些不同于一般哲学方法论的具体写作手法。重点是描述在经验转化为概念过程的作用。哲学描述不是经验的直播,而是设计过的思想桥段。它把经验呈现为观念的结构,同时也克制把哲学理解为只关心抽象的观点。许多重要的哲学创获都是从描述开始的。此外,文章还分析了语义溯源与思想拼贴,在验证观念的深度及思想的普遍性上的特殊作用。用手艺形容这些方法的目的,在于强调哲学的创造性也依赖于可操作的思想训练。

作为文化宗师的孔子是立德、立言的典范。然其立言不仅是某种道德观点的语言表达,而且还在于他通过日常话语做道德教化的方式。《论语》是我们研究其如何把立言与行教相结合的经典文本。作为孔子应答弟子与时人言论的辑录,其核心特征是“答问”,其它独白或描述可以看作“答问”的衍生形式。《论语》答问的要义,是孔子以导师的身份回答求教者在学习、政治与社会生活中碰到的问题。因此,它有别于抽象观念的系统论述。对孔子思想的把握,需要通过语境的分析,才能避免被因人而异或因材施教的现象所迷惑,从而了解看似简易或松散的话语为何拥有重要的表达力量。这方面,行为语言理论以及“作为生活方式的哲学”观点,对研究《论语》的言行问题,或许具有更好的参考价值。

“教育与生产劳动相结合”是马克思主义教育理论的重要原理和基本原则,并内在规定现代劳动教育的内涵、形式及其变革。“教劳结合”中的物质生产劳动和现代教育是历史性概念,它们的内在结合使劳动教育规定和成为现代教育的基本内涵和主要形式。在智能劳动时代,非物质劳动取代物质生产劳动的主导地位,“教劳结合”主要发展为信息化教育、交往教育、情感教育等教育形式和物质劳动与非物质劳动的“内部结合”“多元结合”“交互融合”,也就是“教劳深度融合”,产生劳动教育的“非物质劳动教育”、智能教育转向。“教劳深度融合”的劳动教育为实现生产力巨大发展、劳动解放和人的解放创造主客观条件,实现劳动主体的自我增值和经济、社会、教育创新;实现劳动自由和人的自由的统一,呈现个人自由、个性主体和公共大众的“自由全面发展”。“教劳结合”发展中劳动教育的永恒意义在于:劳育融合、劳动育人;回归劳动教育的“育人”本质;必须坚持历史唯物主义和实践唯物主义方法论。
