Risk of bias and reporting practices in studies comparing VO2max responses to sprint interval vs. continuous training: A systematic review and meta-analysis

Background:It remains unclear whether studies comparing maximal oxygen uptake(VO_{2 max}) response to sprint interval training(SIT) vs.moderate-intensity continuous training(MICT) are associated with a high risk of bias and poor reporting quality.The purpose of this study was to evaluate the risk of bias and quality of reporting in studies comparing changes in VO_{2 max} between SIT and MICT.Methods:We conducted a comprehensive literature search of 4 major databases:AMED,CINAHL,E...     

Use of sport-related concussion information sources among parents of United States middle school children

Objective:Parents may use various information sources to obtain information about sport-related concussions(SRC).This study examined SRCrelated information sources used by parents of United States middle school children(age:10-15 years).Methods:A panel of 1083 randomly selected U.S.residents,aged≥18 years and identifying as parents of middle school children,completed an online questionnaire capturing parental and child characteristics,and utilization and perceived trustworthiness of various sour...     

Cyclic-anion salt for high-voltage stable potassium-metal batteriesOA

Electrolyte anions are critical for achieving high-voltage stable potassium-metal batteries(PMBs).However,the common anions cannot simultaneously prevent the formation of ’dead K’ and the corrosion of Al current collector,resulting in poor cycling stability.Here,we demonstrate cyclic anion of hexafluoropropane-1,3-disulfonimide-based electrolytes that can mitigate the ’dead K’ and remarkably enhance the high-voltage stability of PMBs.Particularly,even using low salt concentration(0.8 M) and addi...     

Rollback,scissor-like closure of the Mongol-Okhotsk Ocean and formation of an orocline:magmatic migration based on a large archive of age dataOA

Tracing the closure of oceans with irregular margins and the formation of an orocline are crucial for understanding plate reconstruction and continental assembly.The eastern Central Asian Orogenic Belt,where the Mongol-Okhotsk orocline is situated,is one of the world’s largest magmatic provinces.Using a large data set of U-Pb zircon ages,we updated the timing of many published igneous rocks,which allowed us to recognize tightly ’folded’ linear Carboniferous-Jurassic magmatic belts that wrap arou...     

澳大利亚、欧洲和北美的医学教育模式

本文论述了澳大利亚、欧洲和北美的医学教育模式.作者指出,医学教育的目标是培训优秀的医生,以便为维护个人和社会的健康服务.但是,为实现这一目标,各国所采取的方法是不同的.在过去30年中,各发达国家对医学教育模式已经进行了重大的改革.本文着重探讨了澳大利亚、欧洲和北美医学教育的理念,对利益共享者所做出的反应,课程模式和内容,以及教学方法、学生的评价和培训计划等.     

美国对学生联邦财政资助政策和原则的基本出发点

本文分析了美国联邦财政对教育的资助及制定资助政策的相关问题:联邦或州政府的职责;教育成本的基本构成;在指导性财政资助中联邦政府和纳税人的作用;学生获得资助或补贴的渠道及相应的国家政策;国家对公立学院和大学的资助范围等。这对于我国筹措教育资金,分解教育成本具有某些启示。
