A guide for the perplexed: Scientific educational research, methodolatry, and the gold versus platinum standards

The paper opens by characterizing recent discourse about empirical educational research as the “new Babel”-critics, using different theoretical vocabularies and making different deep assumptions about the nature of social life, are failing to communicate with each other. After locating some of the critical positions on a left-right continuum, the main discussion focusses upon the end of this continuum where there are located the recent attempts to restore rigor to educational research by using the so-called “gold standard” of randomized field trials. It is argued that positions at this end of the continuum misrepresent the nature of science, and some examples are briefly mentioned in order to covey the point that it is fruitful to view scientists as making convincing cases, cases that appeal to a wide variety of evidence. This assessment of scientific cases is called the “platinum standard”.     

Measuring the Impact of Gold and Green Open Access

Using data from Web of Science, this research investigates how physical science researchers funded by the Canadian Institutes of Health Research complied with its open access policy, and compares the citation counts of articles published through gold and green models.It was found that, for articles published between 2008 and 2015, 9% were available through gold open access routes and 13% were available through green routes; most were not openly accessible. Citation rates were comparable for green open access and non-open access articles, but citation rates for gold open access articles were lower. After controlling for publication year, citation rates of gold, green, and non-open access articles were comparable. Among gold open access articles, citation rates were highest for open access journals with article processing charges, but after controlling for publication year, articles published in hybrid journals, followed by those in open access journals with article processing charges, achieved the highest citation rates. Articles published in free open access journals had the lowest citation rates. The results suggest that green open access is the most economical approach to comply with open access policies, and that it provides researchers with at least as much research impact as gold open access.     

细节刻画 内情外显——《金瓶梅》人物心理描写的表现手法之一

小说《金瓶梅》心理描写的特点是,通过人物的言语和行动,尤其是运用细节,从细微处来省察人物内心的微妙变化,将心理活动呈现在读者面前。在《金瓶梅》之前的中国古代小说,这一手法采用的并不多见,而《金瓶梅》在这一方面却是做得非常成功。这种表现手法似乎已成为作者自觉的行为,这是古代小说观的一个进步。

招平断裂带上盘金矿床石英流体包裹体同位素组成特征及地质意义

招-平断裂是胶东招掖金矿带的主要控矿断裂，其上盘金矿床受NE向断裂构造控制，赋矿围岩为胶东群变质岩，金矿化以含金硫化物石英脉为主。通过首次对招远灵雀山金矿床富金石英脉石英流体包襄体Rb-Sr等时线年龄的测定，获得116±23Ma成矿年龄。从而说明招-平断裂带上盘金矿大规模成矿期发生于早白垩世的构造体系转折期。对富金石英脉石英流体包襄体同位素特征研究表明。该地区成矿热液均以幔源为主，具有与招掖金矿带其它金矿类似的成矿热液系统。由此可以看出招．平断裂带上盘也具有良好的成矿条件。     

综述与诘问:具有中国特色的振兴“三大球”之路

摘要：在文献综述的基础上,在重申振兴三大球的主要目的是在高水平运动竞赛中获取优异成绩的前提下,认为竞技体育的本质规定就是要在比赛中争金夺银。同时,就“振兴三大球究竟需要一个什么样的体制”、“三大球回归学校还有多长的路要走”进行了设问,目的是为走出一条具有中国特色的三大球发展道路提供参考。     

截短平衡Gold序列特性的仿真研究

针对实际扩频通信系统对序列进行截短使用的需要,采用直接序列截短法对所获得的平衡Gold序列进行截短,通过MATLAB平台仿真,分析序列截短前后各方面特性的变化及影响程度.研究表明,序列截短后的平衡性及相关性等性能有所降低,但相比截短前的序列性能仍非常接近.为了保证序列截短后的性能满足实际系统的需求,应选择合适的截短方法和截短长度.     

无氰镀金用亚硫酸金钠含金量的测定

利用重量法和碘量法分别测定了无氰镀金用亚硫酸金钠的含金量。分析比较测定结果,得出较佳测定方法,即二盐酸十亚硫酸钠还原金重量法。该法操作简单,准确度高,标准偏差不大于0.05%。     

社会达尔文主义对我国竞技运动“金牌意识”影响的历史分析

通过分析西方社会达文主义思想对19世纪60年代以来中国体育观念的影响,作者指出中国竞技运动＂金牌意识＂产生的历史原因,并为中国竞技运动克服片面的＂金牌意识＂提出相关建议与参考。
