Technological research in the EU is less efficient than the world average. EU research policy risks Europeans’ future     

Alonso Rodríguez-Navarro  Ricardo Brito 《Journal of Informetrics》2018,12(3):718-731

We have studied the efficiency of research in the EU by a percentile-based citation approach that analyzes the distribution of country papers among the world papers. Going up in the citation scale, the frequency of papers from efficient countries increases while the frequency from inefficient countries decreases. In the percentile-based approach, this trend, which is uniform at any citation level, is measured by the e_p index that equals the P_{top 1%}/P_{top 10%} ratio. By using the e_p index we demonstrate that EU research on fast-evolving technological topics is less efficient than the world average and that the EU is far from being able to compete with the most advanced countries. The e_p index also shows that the USA is well ahead of the EU in both fast- and slow-evolving technologies, which suggests that the advantage of the USA over the EU in innovation is due to low research efficiency in the EU. In accord with some previous studies, our results show that the European Commission’s ongoing claims about the excellence of EU research are based on a wrong diagnosis. The EU must focus its research policy on the improvement of its inefficient research. Otherwise, the future of Europeans is at risk.  相似文献   

Bursting paradigms: a colour wheel of practice-research     

Sophie Hope 《Cultural Trends》2016,25(2):74-86

ABSTRACT

In this article, I question practice as a research paradigm by exploring its position in relation to non-positivist qualitative methodologies. Frayling’s [1994. Research in art and design. Royal College of Art Research Papers, 1(1), 1993/4] distinctions between research into, through, and as (for) practice are expanded to explore overlaps between these approaches. I argue for the need to understand the nuances of different epistemologies and ontologies that underpin diverse disciplinary approaches to practice-research. This is done through an analysis of a selection of Arts and Humanities Research Council (AHRC)-funded projects to find out how they are using and/or embedding practice in the research process. The resulting Colour Wheel of Practice-Research illustrates a spectrum of positions of practice in relation to research, suggesting existing research paradigms are bursting at the seams and that the “disciplinary matrix” of practice might offers other ways of knowing. The reason I have chosen to focus primarily on AHRC-funded projects is because it explicitly states its support of “practice-led research” and that it “remains dedicated to this area of research”. This article aims to add to knowledge of how and why practice-research is of continuing interest to research councils, universities, and those identifying as practice-based/led researchers.  相似文献   

The Impact of an Erasmus Placement in Students’ Perception of their Intercultural Communicative Competence     

Ramiro Durán Martínez  Gloria Gutiérrez  Fernando Beltrán Llavador  Fernando Martínez Abad 《Journal of Intercultural Communication Research》2016,45(4):338-354

Pre- and post-questionnaires answered by UK Nottingham Trent University (NTU) and Spain’s University of Salamanca (USAL) students on their placement abroad support a comparative analysis of its impact on their intercultural communicative competence, comprising the awareness, attitude, skills and knowledge dimensions. NTU students started their placements with better results in them all. Yet, while both groups completed their stay with a similarly increased awareness, the knowledge and skills of the USAL group matched the results of NTU students and, whereas the scores of the attitude dimension towards the host country of NTU students did not increase significantly, those of USAL students decreased.  相似文献   

East Asian pop culture and the trajectory of Asian consumption     

C. J. W.-L. Wee 《Inter-Asia Cultural Studies》2016,17(2):305-315

This article focuses on Chua Beng Huat’s work on the East Asian pop culture that became more prominent in East and Southeast Asia from the 1990s, when the circulation of multilingual and multi-format pop culture started to exceed linguistic, ethnic and national boundaries. It argues that Chua’s work indicates that the pop-cultural production and innovation that support the globalisation and regionalisation processes in East Asia need not be national in origin but can hail from different national origins – and this despite the existing political realities of the region and its history of political fractures. Chua Beng Huat cautions, though, that the national popular can also be marshalled to defeat the border-crossing potential of an inter-Asian pop culture. What is the “Asia” imagined or being represented in such cultural production? Chua’s work is also distinctive in that it deals with the political and economic conditions that underpin mainstream pop consumption as a socio-cultural phenomenon, instead of examining consumption as identity politics. The article concludes by noting the significance that Chua as an institutional builder has played in enabling the study of East Asian pop culture in the region.  相似文献   

The Saljuq Turks’ Conversion to Islam: The Crusading Sources     

Nicholas Morton 《Al-Masaq: Islam & the Medieval Mediterranean》2015,27(2):109-118

This article contributes to the important debate over the conversion of the Turks to Islam. Previously, it was thought that the Turks abandoned their former steppe faith and customs very swiftly to become staunch Sunni Muslims, but this view has recently been challenged by a number of studies. The current consensus seems to be that the Turks’ adoption of Islam was a process of far longer duration, spanning many decades. This article broadens this discussion by demonstrating that the chronicles written by the First Crusaders contain much useful information that is pertinent to this question. It works through these texts, showing that they can shed new light on this point.  相似文献

Kinship,Camaraderie and Contestation: Fāṭimid Relations with the Ashrāf in the Fourth/Tenth Century.     

Shainool Jiwa 《Al-Masaq: Islam & the Medieval Mediterranean》2016,28(3):242-264

The founding of the Fā?imid caliphate across the southern Mediterranean, and then in Egypt, Syria and the ?ijāz at the turn of the fourth/tenth century, necessitated its negotiation with the ashrāf, those who claimed lineal descent from the Prophet Mu?ammad, and who by this time had gained significant influence as a social class based on their charismatic descent. While other dynastic powers fostered relationships with various members of the ashrāf, the Fā?imid–ashrāf dynamics were distinctive in that the Fā?imids legitimised their rule as Ismā?īlī Shī?ī imām-caliphs, based on their claim of descent from the Prophet Mu?ammad, and as the sole successors to his authority and leadership over the Islamic world. Consequently, Fā?imid–ashrāf relations were permeated by fraternal camaraderie as well as by competing contestations based on their shared claim to Prophetic lineage.  相似文献   

Nrf2在有氧运动训练中对小鼠骨骼肌抗氧化能力的作用     

何诗依  张缨 《北京体育大学学报》2017,40(12):50-54

摘要：目的：Nrf2是机体氧化还原平衡的主要调节因子，本研究试图探讨Nrf2在有氧运动训练中对小鼠骨骼肌抗氧化能力的作用。方法：8周龄野生C57BL/6J小鼠和Nrf2敲除小鼠40只，雌雄各半。进一步各为安静组和运动组，每组10只，共4组：分别为野生安静组（WC），野生运动组（WE），敲除安静组（KC）和敲除运动组（KE）。运动组进行4周运动强度为70%VO2max跑速的跑台运动，每周运动6 d，每天运动1 h。运动组最后一次运动后休息48 h脱颈处死，取小鼠后腿骨骼肌。RT-PCR测量Nrf2及Nrf2介导的抗氧化基因mRNA表达量；Western blot法测定骨骼肌Nrf2及抗氧化蛋白含量； GSH试剂盒测量GSH/GSSG比值。结果：1）在安静情况下，KC组和WC组相比，骨骼肌中GSR、NQO1、GCLc、GPX、HO-1和SOD2这6个抗氧化蛋白表达以及GSH/GSSG值没有显著性改变。 2）4周有氧运动训练之后，Nrf2敲除运动组的大部分抗氧化蛋白（CAT, NQO1-1, GCLc, HO-1 and SOD2）和GSH/GSSG值都要显著低于野生运动组。结论：4周70%VO2max强度的有氧运动训练，增加了成年Nrf2敲除和野生鼠骨骼肌抗氧化蛋白表达量和GSH/GSSG比值的差异，而在无训练安静情况下在两种鼠中这些指标的差异不大。说明Nrf2对有氧运动训练中骨骼肌的抗氧化反应起着非常重要的作用。  相似文献   

Anatomical societies find new ways to come together in a post-Covid world     

Rafael Boscolo-Berto  Andrea Porzionato  Carla Stecco  Veronica Macchi  Raffaele De Caro 《Anatomical sciences education》2021,14(6):739-751

The world has been turned upside down by a global health emergency caused by the Covid-19. Given the high contagiousness of the virus and the need to contain its spread, social distancing rules, self-isolation policies, and geographical lockdowns have been enforced globally. Over the pandemic emergency the majority of the planned in-person meetings and congresses of national and international anatomical societies have been postponed or canceled. It is unclear what the future holds, but times of crisis often present possibilities for re-thinking old ways to achieve a more critical approach. It has become increasingly clear that traditional in-person congress formats of scientific societies need to be reevaluated. Over the past year and a half, two types of congressional modalities have been trialed to address the challenge of the pandemic as far as scientific meetings are concerned: the fully virtual congress, in which case the conference program is live streamed to all of the attendees, and the hybrid congress, in which case some of the attendees physically participate at the congress's venue while others interact via a virtual platform. The current study set out to investigate the technical difficulties, social challenges, costs and sustainability, logistics and management issues linked to holding various types of congresses in the post-Covid world. Anatomical societies throughout the world are actively striving to reshape their response to the current global emergency and to uncover new types of conference modalities in the effort to keep scientific exchange alive and flourishing in the post-Covid era.  相似文献   

优秀女子足球运动员间歇性恢复能力的评价研究     

秦旸  张娜 《南京体育学院学报(社会科学版)》2016,(2):103-107

目的：：探讨运用限定级数YO-YO IR2测试以及心率恢复速率评价我国优秀女足运动员的间歇恢复能力。方法：运用测试法对2013年冬训期间的10名国家女足运动员进行YO-YO IR2测试、心率监控以及比赛监测，采集运动员测试跑动距离、心率特征以及比赛中高强度跑动距离，进行统计学分析。结论：女足运动员YO-YO IR2测试结果以及心率恢复速率与比赛中的高强度跑动能力具有紧密相关性，提示YO-YO IR2测试以及心率监控可以作为评价女足运动员间歇性恢复能力的有效方法。与传统的力竭性YO-YO IR2测试法相比，采用限定级数的YO-YO IR2测试后的心率恢复速率评价更易于女足运动员接受，在训练中具有更好的适用性。  相似文献
