Ranking scientific articles based on bibliometric networks with a weighting scheme

As the volume of scientific articles has grown rapidly over the last decades, evaluating their impact becomes critical for tracing valuable and significant research output. Many studies have proposed various ranking methods to estimate the prestige of academic papers using bibliometric methods. However, the weight of the links in bibliometric networks has been rarely considered for article ranking in existing literature. Such incomplete investigation in bibliometric methods could lead to biased ranking results. Therefore, a novel scientific article ranking algorithm, W-Rank, is introduced in this study proposing a weighting scheme. The scheme assigns weight to the links of citation network and authorship network by measuring citation relevance and author contribution. Combining the weighted bibliometric networks and a propagation algorithm, W-Rank is able to obtain article ranking results that are more reasonable than existing PageRank-based methods. Experiments are conducted on both arXiv hep-th and Microsoft Academic Graph datasets to verify the W-Rank and compare it with three renowned article ranking algorithms. Experimental results prove that the proposed weighting scheme assists the W-Rank in obtaining ranking results of higher accuracy and, in certain perspectives, outperforming the other algorithms.     

鱼腥草水培营养液的筛选

采用水培方式研究了6种常用营养液配方对鱼腥草生长和品质的影响,探讨了鱼腥草水培适宜的营养液配方。结果表明,6种营养液配方对水培鱼腥草生长无显著影响,但对其可溶性糖含量和叶绿素含量有显著影响。水培鱼腥草可溶性糖含量以霍格兰配方最高,较对照增加179．26％;叶绿素含量以霍格兰配方最高,较对照增加56．15％。鱼腥草水培营养液配方以霍格兰配方较为适宜。     

The trend of body donation for education based on Korean social and religious culture

Until a century ago, Korean medicine was based mainly on Oriental philosophies and ideas. From a religious perspective, Chinese Confucianism was prevalent in Korea at that time. Since Confucianists believe that it is against one's filial duty to harm his or her body, given to them by their parents, most Koreans did not donate their bodies or organs for education in the past. However, by the end of the 20th century, a unique fusion of Western and Oriental medicines were produced on the Korean Peninsula, revolutionizing traditional perspectives on the human body, mortality, and the relationship of medical science to society. Koreans began to think about others' lives as well as their own by realizing the importance of donating one's organs and bodies for scientific purposes. Since then, the number of people donating their bodies to Korean medical and dental schools for the purpose of improving academic learning has increased dramatically. In response, Korean medical schools have begun to hold various types of funeral ceremonies to honor body donors. We have compared such ceremonies performed in Korea with those performed in the United States of America and Taiwan. These ceremonies are viewed as a suitable way to pay proper respect to the dead and to promote knowledge about body donation programs in Korea. Overall, the transition of religions and social ethics in Korea has greatly facilitated body bequeathal programs, benefiting both medical education and the Korean public health administration.     

Globally exponentially stable single beacon underwater navigation with unknown sound velocity estimation

Single beacon navigation methods with unknown effective sound velocity (ESV) have recently been proposed to solve the performance degeneration induced by ESV setting error. In these methods, a local linearization-based state estimator, which only exhibits local convergence, is adopted to estimate the navigation state. When the initial ESV setting error or vehicle initial position error is large, the local linearization-based state estimators have difficulty guaranteeing the filtering convergence. With this background, this paper proposes a linear time-varying single beacon navigation model with an unknown ESV that can realize global convergence under the condition of system observability. A Kalman filter is adopted to estimate the model state, and the corresponding stochastic model is inferred for the application of the Kalman filter. Numerical simulation confirms that the proposed linear time-varying single beacon navigation model can realize fast convergence in the case of a large initial error, and has superior steady-state performance compared with the existing methods.     

我国艺术体操个人项目器械技术选编现状与问题剖析

运用文献资料、数理统计、分析归纳、录像观察等研究方法,对2010年艺术体操“全国冠军赛”成年个人单项决赛前8名运动员的四项器械成套动作进行深层研究与梳理.结果表明:器械技术价值的选编低空降低成套动作编排档次,数量的选编稀疏阻碍成套动作编排空间,类型的选编平淡影响成套动作编排品味.因此,在拓宽器械运用和完美质量的前提下,进一步开拓编排思绪,充分利用器械技术这一可控因素提高成套动作的价值.     

高职院校学生艺术兴趣爱好培养之我见

艺术是美的结晶,美的体现,蕴含着深刻的思想内涵,它寓教于乐,寓教于美,可以潜移默化地影响人、改造人。艺术教育的目的就在于引导学生发现美、认识美、创造美,激发学生对美的热爱和追求,使其道德、情操、精神得到不断升华,达到完善和谐的境界,树立起正确的世界观和人生观。通过艺术教育,可以比较容易地使学生取得成功,而艺术教育的成功又能有效地增强学生的自信心,促进学生在其他方面的进步。加强艺术教育,培养大学生对艺术的兴趣爱好,实践＂立美育人＂,是高职教育发展的现实选择。

四川省少数民族地区城镇居民参与体育活动现状与对策研究

采用文献资料、问卷调查等方法,对四川甘孜自治州、阿坝藏族羌族自治州、凉山彝族自治州少数民族地区居民体育现状进行了调查分析,结果表明：参与体育锻炼的居民大多选择简便易行、对场地要求不高、消费性支出不显著的运动项目进行自发的体育锻炼,而大多数居民不参与体育锻炼的主要原因是缺乏余暇时间和劳动后的身心疲惫。针对这种现状,提出优先为行政村开展全民健身活动,提供必要的人、财、物方面的扶持和帮扶力度等对策和建议。
