论教育研究中的深度思维

研究者分析教育问题、解释教育现象、概括教育特征和阐释教育思想能力之间的差别,体现了其深度思维品质的差异。教育研究者的深度思维品质主要体现在基于对教育现象之想象力的联想思维、基于对教育行为之合理性的透视思维、基于对教育权威之超越性的批判思维、基于对教育思想之涌动性的具身思维四个方面。培植和发展研究者的深度思维,引导研究者进入观点触类旁通、反思深邃深刻、批判合理合情、思想诗性灵动的思维新境界,应当成为教育者的自觉担当。     

科技期刊利用互联网资源进行策划组稿的实践——以《国际检验医学杂志》为例

对于科技期刊而言,质量仍然是期刊可持续发展的根本.提高科技期刊质量的途径和方法很多,其中,编辑部主动向专家进行组稿约稿是科技期刊始终保持在同质期刊中的权威性,提升期刊质量和影响力最常见又切实可行的方法.本文以《国际检验医学杂志》为例,探讨如何利用互联网资源,如微信“问卷星”调查、百度学者、国家自然科学基金委员会官网等,及时了解专家的论文影响力、研究方向和最新成果等,并进行精准的策划组稿,取得较好效果.     

自我拯救与自我毁灭——浅论《红字》中的罪与罚意识

本文通过对文中海丝特·白兰与丁姆斯代尔各自罪与罚的探讨，进一步阐释作品主题，同时从另一个侧面去理解作者的思想体系与创作心理动机。     

Precision measurement of the Newtonian gravitational constant

The Newtonian gravitational constant G, which is one of the most important fundamental physical constants in nature, plays a significant role in the fields of theoretical physics, geophysics, astrophysics and astronomy. Although G was the first physical constant to be introduced in the history of science, it is considered to be one of the most difficult to measure accurately so far. Over the past two decades, eleven precision measurements of the gravitational constant have been performed, and the latest recommended value for G published by the Committee on Data for Science and Technology (CODATA) is (6.674 08 ± 0.000 31) × 10⁻¹¹ m³ kg⁻¹ s⁻² with a relative uncertainty of 47 parts per million. This uncertainty is the smallest compared with previous CODATA recommended values of G; however, it remains a relatively large uncertainty among other fundamental physical constants. In this paper we briefly review the history of the G measurement, and introduce eleven values of G adopted in CODATA 2014 after 2000 and our latest two values published in 2018 using two independent methods.     

余华小说《第七天》中的生与死

《第七天》是余华继《兄弟》七年之后完成的最新一部长篇小说，描绘了主人公死去后所经历的事情以及勾起的回忆，为读者展现了一个平等、和谐的死亡世界。经过分析，作品中的生死问题包括三个方面：作品中的人物对死亡没有痛苦或恐惧，能够理性地看待死亡；生与死的意义被颠倒，死亡世界接近理想中的现实世界，更加引人向往；生与死由“爱”这条纽带联系起来，让人们在冰冷中感受到温情。这部小说暴露了大量的社会现实，引人深思，也备受争议。     

Wearable skin-like optoelectronic systems with suppression of motion artifacts for cuff-less continuous blood pressure monitor

According to the statistics of the World Health Organization, an estimated 17.9 million people die from cardiovascular diseases each year, representing 31% of all global deaths. Continuous non-invasive arterial pressure (CNAP) is essential for the management of cardiovascular diseases. However, it is difficult to achieve long-term CNAP monitoring with the daily use of current devices due to irritation of the skin as well as the lack of motion artifacts suppression. Here, we report a high-performance skin-like optoelectronic system integrated with ultra-thin flexible circuits to monitor CNAP. We introduce a theoretical model via the virtual work principle for predicting the precise blood pressure and suppressing motion artifacts, and propose optical difference in the frequency domain for stable optical measurements in terms of skin-like devices. We compare the results with the blood pressure acquired by invasive (intra-arterial) blood pressure monitoring for >1500 min in total on 44 subjects in an intensive care unit. The maximum absolute errors of diastolic and systolic blood pressure were ±7/±10 mm Hg, respectively, in immobilized, and ±10/±14 mm Hg, respectively, in walking scenarios. These strategies provide advanced blood pressure monitoring techniques, which would directly address an unmet clinical need or daily use for a highly vulnerable population.
