规范使用SCI下科技评价的问题与解决路径研究

[目的/意义]教育部、科技部2020年发布了《关于规范高等学校SCI论文相关指标使用树立正确评价导向的若干意见》,对意见推广后可能存在的问题进行深度分析并提出改进思路具有重要意义。[方法/过程]本文从评价对象、评价方法、评价目的、评价管理等方面进行分析,对规范使用SCI论文评价的适用范围与存在问题进行探讨。[结果/结论]研究发现,规范使用SCI存在少部分SCI期刊质量不高、SCI论文只适用于微观评价、代表作“代表性”不够、数量指标与质量指标难以兼顾、评价管理有待改进等等问题。提出了如下政策建议:以高水平SCI期刊作为评价依据;强化黑名单制度;宏观评价要发挥SCI论文的主导作用;鼓励采用一些文献计量指标进行评价;微观评价建议兼顾代表作与SCI论文数量;一般高校对研究生毕业论文应该有所要求。最后指出,SCI论文的规范应用需要深化高校科技管理体制改革;解决SCI论文的评价问题需要循序渐进;要重视SCI论文的科研符号功能。     

国家治理信息机制的要素分析

文章认为信息机制不仅具有国家治理体系的属性,而且属于国家治理能力范畴,信息机制不仅是一种信息管理的制度安排,也是政府信息能力的体现。文章提出了价值观念、制度安排、组织实体和信息工具的信息机制四要素分析框架,阐述了信息机制四要素的内涵及相互关系,提出了在开放科学的理念引领下,构建信息、资源和处置权相配套的制度体系,加强多元协同的政策共同体建设,增强信息工具的公共物品属性,四要素综合协调,多维度发力的完善国家治理信息机制路径。     

Genetic analysis of fruit shape traits at different maturation stages in sponge gourd

The fruit shape is important quantitative trait closely related to the fruit quality. However, the genetic model of fruit shapes has not been proposed. Therefore, in the present study, analysis of genetic effects for fruit shape traits （fruit length and fruit perimeter） in sponge gourd was conducted by employing a developmental genetic model including fruit direct effects and maternal effects. Analysis approaches of unconditional and conditional variances were applied to evaluate the genetic behavior of fruit shape traits at economical and physiological maturation times. The results of variance analysis indicated that fruit length and fruit perimeter were simultaneously affected by fruit direct genetic effects and maternal effects. Fruit direct genetic effects were relatively more important for fruit shape traits at whole developmental period. The gene expression was most active at the economical maturation stage （1-12 d after flowering） for two shape traits, and the activation of gene was mostly due to direct dominance effects at physiological maturation stage （13-60 datter flowering）. The coefficients due to different genetic effects, as well as the phenotypic correlation coefficients, varied significantly between fruit shape traits themselves at various maturation stages. The results showed that it was relatively easy to improve fruit shape traits for industrial purpose by carefully selecting the parents at economical maturation stage instead of that at physiological maturation stage.

Dynamic Stability Analysis of Cages in High-Speed Oil-Lubricated Angular Contact Ball Bearings

To investigate the cage stability of high-speed oil-lubricated angular contact ball bearings, a dynamic model of cages is developed on the basis of Gupta’s and Meeks’ work. The model can simulate the cage motion under oil lubrication with all six degrees of freedom. Particularly, the model introduces oil-film damping and hysteresis damping, and deals with the collision contact as imperfect elastic contact. In addition, the effects of inner ring rotational speed, the ratio of pocket clearance to guiding clearance and applied load on the cage stability are investigated by simulating the cage motion with the model. The results can provide a theoretical basis for the design of ball bearing parameters.

简论裕固族“小说四家”的创作

新世纪以来的裕固族小说作家大多采用了汉语书面写作的方式去表达思想、传播文化,表达了作家在新的文化语境中书写族群文化史的主体性反应与时代性调适。达隆东智、铁穆尔、杜曼、苏柯静想以各自相对成熟的写作风格可以被视之为新世纪以来的"裕固族小说四家"。     

某空腹式双曲拱桥承载力现场测试与分析

为检验在役双曲拱桥的承载能力与动力特性,对某净跨为36 m空腹式双曲拱桥进行了静载试验、动载试验及空间有限元分析。测试结构的静态应变、动态应变、挠度、自振频率、振型及加速度等结构反应,计算得出冲击系数。将实测结果与有限元结果进行对比分析,结果表明:应变校验系数为0.5~0.9,结构具有较好承载力。实测的各阶频率及相应振型与有限元计算结果比较吻合,桥梁整体竖向刚度较好。     

戴震《诗经》学三题

学界颇为重视戴震<诗经>学名物训诂方面的成就,而忽略了关涉其义理观的三个重要成果:1.定"思无邪"为说<诗>宗旨,强调"姑以",结合其"一诗数用"说,可见选取该宗旨说<诗>的价值取向和方法论考虑;2.提出与前人完全不同的"四始"、"正变"新说,为<诗>学研究提供了新的学理依据;3.将二<雅>作出不同于前人,亦不合"什"...     

汉代四家《诗》立于学官考辨

《毛诗》于平帝元始五年立于学官,终王莽之世。《鲁诗》立于学官在武帝为博士置弟子员之后。《齐诗》立于学官不迟于昭帝元凤元年。《韩诗》可能是在昭帝始元五年立于学官。学者或以为三家《诗》立于文景之世,或以为立于武帝置五经博士时,或以为三家分派在石渠阁会议之后,以及以为《毛诗》是元始四年立于学官的,都是错误的。文景之时尚无专经博士;武帝置五经博士明确了其顾问团为儒家性质,当时经派意识尚不明晰;石渠阁会议之前三家已经分派,史书叙宣帝增置前博士不数《诗》博士,是因《诗》博士在宣帝增立时无所增立。
