Improving network service performance and reliability via links trunking technologies

INTRODUCTION Because of the critical role that computing sys-tems and networks play in today’s business envi-ronment, it is not surprising that business success often goes to the company with the best information and the most efficient process for delivering that in-formation. As the principal tool for business col-laboration, corporate LANs are a vital resource in enabling today’s enterprises to adopt competitive strategies. The number of users wanting to share and access data across…     

How silicon fertilizer improves nitrogen and phosphorus nutrient availability in paddy soil?

In order to reveal the mechanism of silicon(Si) fertilizer in improving nitrogen(N) and phosphorus(P) nutrient availability in paddy soil, we designed a series of soil culture experiments by combining application of varying Si fertilizer concentrations with fixed N and P fertilizer concentrations. Following the recommendations of fertilizer manufacturers and local farmers, we applied Si in concentrations of 0, 5.2, 10.4, 15.6, and 20.8 μg/kg. At each concentration of added Si, the availability of soil N and P nutrients, soil microbial activity, numbers of ammonia-oxidizing bacteria and P-decomposing bacteria which means that the organic P is decomposed into inorganic nutrients which can be absorbed and utilized by plants, and urease and phosphatase activity first increased, and then decreased, as Si was added to the soil. These indicators reached their highest levels with a Si application rate of 15.6 μg/kg, showing values respectively 19.78%, 105.09%, 8.34%, 73.12%, 130.36%, 28.12%,and 20.15% higher than those of the controls. Appropriate Si application(10.4 to 15.6 μg/kg) could significantly increase the richness of the soil microbial community involved in cycling of N and P nutrients in the soil. When the Si application rate was15.6 μg/kg, parameters for characterizing microbial abundance such as sequence numbers, operational taxonomic unit(OTU)number, and correlation indices of microbial community richness such as Chao1 index, the adaptive coherence estimator(ACE)index, Shannon index, and Simpson index all reached maximum values, with amounts increased by 14.46%, 10.01%, 23.80%,30.54%, 0.18%, and 2.64%, respectively, compared with the control group. There is also a good correlation between N and P mineralization and addition of Si fertilizer. The correlation coefficients between the ratio of available P/total P(AP/TP) and the number of ammonia-oxidizing bacteria, AP/TP and acid phosphatase activity(AcPA), AP/TP and the Shannon index, the ratio of available N/total amount of N(AN/TN) and the number of ammoniated bacteria, and AN/TN and AcPA were 0.9290, 0.9508,0.9202, 0.9140, and 0.9366, respectively. In summary, these results revealed that enhancement of soil microbial community structure diversity and soil microbial activity by appropriate application of Si is the key ecological mechanism by which application of Si fertilizer improves N and P nutrient availability.     

中国传统文化中的境界学说及其当代教育意义

追求人生的境界是中国传统文化的精髓。中国传统文化中的境界学说以儒释道三家为代表。儒家文化注重人性修养、道德养成与人生境界的提升,以推崇“圣贤”作为其境界追求;道家主张让人超越名利,通过出世修行,摆脱外在干扰,获得真正的自由与解放,成为“真人”是其境界追求;佛教侧重通过“戒、定”获得“慧”,去除欲望,消除痛苦,最终达至“圆满”之境界。新儒家将传统境界学说推向新的高度,形成了“多层次”的境界思想。教育从本质上是培养人的活动,是人文化成的过程,而境界则是人之为人的重要精神标识,也是教育的根本价值指向。中国传统文化中的境界学说对于当代的教育具有重要的意义,即培育有境界的人是当代中国教育的理想追求;强调体悟、践行是当代中国教育的行动逻辑;注重家国一体是当代中国教育的重要使命;开展境界教育则是当代中国教育的必要途径。     

本科毕业设计存在的问题与整改措施探析

本科毕业设计是提高学生综合素质、培养学生实践能力与创新精神的必需环节,是高校人才培养计划的重要组成部分。然而,近年来本科毕业论文的质量明显下滑。我们结合2016年应用物理学专业毕业设计的抽检结果,对毕业设计出现的问题进行分析,提出了针对性的整改措施。在此基础上,对2017年该专业毕业设计环节进行严格把控,取得了明显的整改效果。

美国大学教师聘任制中学术职业利益保障机制探析

作为市场驱动型的高等教育系统，美国大学教师聘任制的制度设计充分体现了市场机制的作用。与此同时，在大学中，学术职业有着自己独特的、与其任教大学机构相关的纪律、职业和物质利益。因此，美国大学教师聘任制在市场机制的作用下，在强调学术生产率的同时，通过基于学术自由的理念和学术共同体的内部规范长期发展起来的有效的学术管理机制，形成了在市场高度竞争的学术环境中对学术职业利益的一种保护和制衡机制。在这两种机制之间维持一种张力正是美国大学教师聘任制成功并为其他国家所借鉴的重要原因。     

中学生网络学习调查研究

随着网络教育的发展和教育部“校校通”工程的实施,许多中小学生开始接触或参与网络教育,研究发现在网络学习中大约有三分之一的中学生存在各种各样的学习问题,不能适应网络学习,本文将采用课堂观察和问卷调查的研究方式,来探讨这一问题。     

性本非善——孟子性善论析判

孟子以其"民贵君轻"的民本思想和"舍生取义"、"富贵不可淫,贫贱不可移,威武不可屈"的士大夫精神享誉中国2000多年.但从现代心理学和公认的价值观角度看,孟子的性善学说是传统中国社会(特别是宋明以来)虚幻文化心理的集中体现,对中国封建社会的长期停滞负有不可推卸的责任,并严重阻碍我国100多年前已开始而目前尚未完成的民族启蒙运动和现代化建设.
