论中国道路的新现代性逻辑

经典现代性、资本现代性、多元现代性以及反思性现代性等都无法有效阐释中国道路,它是一条不同于以往现代化模式的新现代性道路。其一,中国道路超越了资本现代性逻辑,呈现出"社会主义制度逻辑"。其二,中国道路超越了传统社会主义逻辑,吸纳了"市场经济逻辑"。其三,中国道路超越了西方"串联式发展逻辑",表现为以新型工业化为特征的"并联式发展逻辑"。     

构建开放教育中《计算机应用基础》课程的学习支持服务体系

远程开放教育就是以学生为中心的全方位的助学服务;远程开放教育的教的过程就是为学生提供全方位学习支持服务的过程,而学的过程就是学生使用、接受服务的过程,做好学习支持服务是确保开放教育顺利进行的保证。本文主要从《计算机应用基础》课程的导学过程来说明是如何为开放教育学员提供完善的支持服务的。

Serrated lithium fluoride nanofibers-woven interlayer enables uniform lithium deposition for lithium-metal batteries

The uncontrollable formation of Li dendrites has become the biggest obstacle to the practical application of Li-metal anodes in high-energy rechargeable Li batteries. Herein, a unique LiF interlayer woven by millimeter-level, single-crystal and serrated LiF nanofibers (NFs) was designed to enable dendrite-free and highly efficient Li-metal deposition. This high-conductivity LiF interlayer can increase the Li⁺ transference number and induce the formation of ‘LiF–NFs-rich’ solid–electrolyte interface (SEI). In the ‘LiF–NFs-rich’ SEI, the ultra-long LiF nanofibers provide a continuously interfacial Li⁺ transport path. Moreover, the formed Li–LiF interface between Li-metal and SEI film renders low Li nucleation and high Li⁺ migration energy barriers, leading to uniform Li plating and stripping processes. As a result, steady charge–discharge in a Li//Li symmetrical cell for 1600 h under 4 mAh cm⁻² and 400 stable cycles under a high area capacity of 5.65 mAh cm⁻² in a high-loading Li//rGO–S cell at 17.9 mA cm⁻² could be achieved. The free-standing LiF–NFs interlayer exhibits superior advantages for commercial Li batteries and displays significant potential for expanding the applications in solid Li batteries.     

Combination of Se-methylselenocysteine,D-α-tocopheryl succinate, β-carotene,and L-lysine can prevent cancer metastases using as an adjuvant therapy

ObjectivePrimary tumor treatment through surgical resection and adjuvant therapy has been extensively studied, but there is a lack of effective strategies and drugs for the treatment of tumor metastases. Here, we describe a functional product based on a combination of compounds, which can be used as an adjuvant therapy and has well-known mechanisms for inhibiting cancer metastases, improving anti-cancer treatment, and enhancing immunity and antioxidant capacity. Our designed combination, named MVBL, consists of four inexpensive compounds: L-selenium-methylselenocysteine (MSC), D-‍α‍-tocopheryl succinic acid (VES), β‍-carotene (β‍-Ca), and L-lysine (Lys).MethodsThe effects of MVBL on cell viability, cell cycle, cell apoptosis, cell migration, cell invasion, reactive oxygen species (ROS), and paclitaxel (PTX)-combined treatment were studied in vitro. The inhibition of tumor metastasis, antioxidation, and immune enhancement capacity of MVBL were determined in vivo.ResultsMVBL exhibited higher toxicity to tumor cells than to normal cells. It did not significantly affect the cell cycle of cancer cells, but increased their apoptosis. Wound healing, adhesion, and transwell assays showed that MVBL significantly inhibited tumor cell migration, adhesion, and invasion. MVBL sensitized MDA-MB-231 breast cancer cells to PTX, indicating that it can be used as an adjuvant to enhance the therapeutic effect of chemotherapy drugs. In mice, experimental data showed that MVBL inhibited tumor metastasis, prolonged their survival time, and enhanced their antioxidant capacity and immune function.ConclusionsThis study revealed the roles of MVBL in improving immunity and antioxidation, preventing tumor growth, and inhibiting metastasis in vitro and in vivo. MVBL may be used as an adjuvant drug in cancer therapy for improving the survival and quality of life of cancer patients.     

浅谈高速公路建设中不良地质的研究方法

随着我国高速公路网建设的不断实施,我国高速公路现已经进入建设的高潮时期,使得高速公路建设中所面临的地质灾害问题也日趋严峻。在高速公路建设中,准确判定和划分不良地质是一项必不可少但又具一定难度的工作。本文将对现今常用的综合物探以及遥感技术在高速公路建设中勘探调查方法技术作一论述和探讨。

日本基础教育中的学业成就制约因素分析

自2002年以来,日本的一些研究人员开始对学业成就和社会阶层的关系进行调查研究。本文使用“日本教育纵向调查”的2003年数据考察影响儿童学业成就的诸因素以及这些因素的外延,主要分析结果为：1、某地方小城市的调查结果显示各社会阶层儿童的学业成就差距相对较小;2、位于首都圈的某中等城市的调查结果显示儿童的学业成就受到教育费支出、教育期待和家庭收入的影响。     

生态型人工自然——和谐社会的人工自然形态

人工自然是人类实践的产物,与人类社会有着相辅相成的关系。由于人工自然自身特性及外部原因,造成了其异化的不良后果。在建设和谐社会的进程中,为了克服人工自然其异化后果,应该发展生态型人工自然,并从政治环境、文化环境、法律环境对其发展提供保障,惟此才能促进和谐社会乃至和谐世界的建立。     

道德教育的期待:人之自我超越

自我超越是人的生存本性。生活意义的超越是自我超越的基本涵义。自我超越的可能存在于人的两重化结构之中。引导人的自我超越是教育的根本使命。"我可能是什么"是教育要促使人永远向自己提出的问题。良心的召回是当代教育所面对的历史重任。
