A focus on quality--the library's role in occurrence screening

One of the highest priorities in today's hospitals is the provision of quality care to patients. The medical librarian has an increased responsibility to furnish quality information to the medical staff. Traditional methods of reference service continue to work well, but it is increasingly important for librarians to become more directly involved in hospital quality assurance (QA) activities. Occurrence screening is one system of QA where the librarian can make a difference.

"比特"与"字节"单位符号规范化标注建议

国家标准未对单位"比特"和"字节"的符号做出明确规定,因此,在论文中对它们的标注很不统一.针对这一问题,简要介绍比特、字节的物理概念,分析"比特"和"字节"单位符号的使用现状,并提出规范化标注的建议.     

事件理论视域下的体育概念探究

体育概念是长期以来一直存在的一个基本理论问题,是关于体育“是什么”“为什么”以及“如何是”的理性思考,体育的非实体特征、体育行为的心—物二元关系及体育文化深刻历史性和社会性,使得长期以来一直存在着“此体育与彼体育”的价值错位和子项兼容,这需要进一步由“体”返回“本”,继续探寻被遮蔽体育之“本”。研究认为,事件理论下,体育是主体基于场地、器材、教练、裁判等体育事物而进行的有意识的事件集合,是一个相互联结、包容的,持续发展的系统。     

开展数学实验 培养创造才能——《初中数学、普通高中数学实验教学基本目录》解读

为有效贯彻教育部《基础教育课程教学改革深化行动方案》,落实《关于加强和改进中小学实验教学的意见》相关要求,强化科学教育,教育部教育技术与资源发展中心(中央电化教育馆)于2023年11月23日正式发布了《中小学实验教学基本目录(2023年版)》。文章在一定的理论分析和教学实践的基础上,从数学实验的内涵、数学实验的价值、数学实验教学的建议三方面解读了《初中数学实验教学基本目录》和《普通高中数学实验教学基本目录》,阐述了如何通过开展数学实验,培养学生的创造才能。     

用好数字 用活数字

新闻采访与报道往往离不开数字。数字是事物量变和质变的尺码,是记者在采访报道中无可逃避而又苦苦寻觅的绝好素材,其重要性不言而喻。但是,如果数字用得过多过滥,或者用得不恰当,新闻报道就会枯燥乏味,难以给受众留下深刻的印象,它所承载的意义也就难以显现,甚至还会成为阅读收听、收看的障碍,这已经成为当今新闻报道的一大问题。笔者总结如下几种方法,供参考。     

Temporal aspects of the VO2 response at the power output associated with VO2peak in well trained cyclists--implications for interval training prescription

The power output achieved at peak oxygen consumption (VO2peak) and the time this power can be maintained (i.e., Tmax) have been used in prescribing high-intensity interval training. In this context, the present study examined temporal aspects of the VO2 response to exercise at the cycling power that output well trained cyclists achieve their VO2peak (i.e., Pmax). Following a progressive exercise test to determine VO2peak, 43 well trained male cyclists (M age = 25 years, SD = 6; M mass = 75 kg, SD = 7; M VO2peak = 64.8 ml x kg(-1) x min(-1), SD = 5.2) performed two Tmax tests 1 week apart. Values expressed for each participant are means and standard deviations of these two tests. Participants achieved a mean VO2peak during the Tmax test after 176 s (SD = 40; M = 74% of Tmax, SD = 12) and maintained it for 66 s (SD = 39; M = 26% of Tmax, SD = 12). Additionally, they obtained mean 95% of VO2peak after 147 s (SD = 31; M = 62% of Tmax, SD = 8) and maintained it for 95 s (SD = 38; M = 38% of Tmax, SD = 8). These results suggest that 60-70% of Tmax is an appropriate exercise duration for a population of well trained cyclists to attain VO2peak during exercise at Pmax. However, due to intraparticipant variability in the temporal aspects of the VO2 response to exercise at Pmax, future research is needed to examine whether individual high-intensity interval training programs for well trained endurance athletes might best be prescribed according to an athlete's individual VO2 response to exercise at Pmax.
