Divergent production in gifted adolescents using timed vs. untimed stimuli with creative prompting     

Gregg A. Johns  Linda W. Morse  David T. Morse 《Roeper Review》2013,35(3):165-166

Although creativity and expertise are related, they are nonetheless very different things. Expertise does not usually require creativity, but creativity generally does require a certain level of expertise. There are similarities in the relationships of both expertise and creativity to domains, however. Research has shown that just as expertise in one domain does not predict expertise in other, unrelated domains, creativity in one domain does not predict creativity in other, unrelated domains. People may be expert, and people may be creative, in many domains, or they may be expert, or creative, in few domains or none at all, and one cannot simply transfer expertise, or creativity, from one domain to another, unrelated domain. The domain specificity of creativity matters crucially for creativity training, creativity assessment, creativity research, and creativity theory. The domain specificity of creativity also means that interdisciplinary thinking, interdisciplinary collaboration, and interdisciplinary creativity are even more important than one would assume if creativity were domain general.  相似文献

场域论与体育社会学研究   总被引：2，自引：1，他引：1  

高强 《体育学刊》2010,17(1)

从阐述皮埃尔·布迪厄场域论的基本概念与其对法国体育社会学的影响出发,具体探讨了场域论在体育概念的发展和身体概念的引入上对体育社会学研究的意义,进而分析惯习、资本和场域这3大概念在体育社会学研究中的发展,及在批判和实践应用的视角下场域论的实践应用意义.最后通过发展场域论对主观主义和客观主义隔阂的消除及"研究主体"的研究价值的确定,来反思中国体育社会学研究.  相似文献   

基于分块和统计相结合的新闻正文抽取   总被引：1，自引：0，他引：1  

李烯  徐朝军 《情报理论与实践》2010,33(1)

本文提出一种结合网页分块与统计的方法来抽取新闻类网页中的正文。首先,在网页解析的基础上根据标签信息对网页进行分块处理,并计算出每一个内容块的实际长度;其次,在得到内容块的长度集合后,计算这些内容块长度的均值,同时利用方差能反映一组数据的波动大小的特性,按内容块长度降序排列并依次计算去掉最大内容块后的方差变化情况,寻找最有可能的正文内容块;最后随机选取了一些新闻网页进行测试,结果显示准确率可达96%,充分证明了该方法的有效性。  相似文献   

Emotional energy and sub-cultural politics: alternative bands in post-1997 Hong Kong     

Eric Ma 《Inter-Asia Cultural Studies》2013,14(2):187-200

The paper attempts to work out the link between the structuring of the public domain and hegemonic masculinities in contemporary Kerala, South India. Using the debates around an incident of sexual harassment that happened in 1999, it argues for a conjunctural understanding of the contemporary where various events and moments in history are replayed through narrativization and popular memory. The paper goes on to analyse the debates around the incident that produce a ‘narrative public domain’, to foreground the various notions of masculinity that construct and structure it in relation to notions of female sexuality and changing structures of family. These notions of masculinity could be, the paper argues, a starting point for a historical inquiry into Kerala's modernity – an inquiry that would throw light on the past and the ways in which the contemporary is produced through its historical legacies.  相似文献   

Referential perspective and instruction: A study on teacher-student interaction and text remembering     

Santamaría  Andrés  de la Mata  Manuel L. 《Instructional Science》2002,30(2):129-152

The aim of this paper is to study the role ofteacher-student interaction, in the acquisitionof text comprehension and memory skills from asocio-cultural approach. In our view, one ofthe most important areas of neglect in cognitive research in this field is the interactional nature of that development. We intend to establish the way in which teacher-student interaction and, specially, the use of some specific semiotic means mayfacilitate the acquisition and internalizationof general strategies for understanding andremembering expository texts. The role ofreferential perspective (Wertsch, 1989) in theinternalization of complex text study actionsis analysed.The task was to study three expository textsthat were similar in their structure. Thecontent of the texts was analysed in terms ofidea-units (Meyer, 1984). Each text was formedby idea-units from three different levels: mainideas, secondary ideas and details. A categorysystem for the analysis of study and recall ofthe text is developed. In the study phase theanalysis proceeded in two steps: study actionsand text ideas. In the recall phase, two types ofindexes (number of ideas and degree ofclustering) were considered. For the analysisof instructional actions, both the nature ofinstruction and referential perspective wasrecorded.  相似文献   

语篇教学     

李东升 《中国教育研究与创新》2006,3(9):25-26

从某种程度上说，语言教学其实就是语篇教学。在语义系统网络所提供的意义潜势与语类图武结构形成的结构潜势的相互作用下我们就能够生成恰当的言语。语篇教学在很大程度上就是培养学习者根据语类结构潜势选择得体的语言来表达功能意义的能力。  相似文献   

An efficient method of addressing ectopic beats: new insight into data preprocessing of heart rate variability analysis     

Wen F  He FT 《Journal of Zhejiang University. Science. B》2011,12(12):976-982

Heart rate variability (HRV) analysis is affected by ectopic beats. An efficient method was proposed to deal with the ectopic beats. The method was based on trend correlation of the heart timing signal. Predictor of R-R interval (RRI) value at ectopic beat time was constructed by the weight calculation and the slope estimation of preceding normal RRI. The type of ectopic beat was detected and replaced by the predictor of RRI. The performance of the simulated signal after ectopic correction was tested by the standard value using power spectrum density (PSD) estimation, whereas the results of clinical data with ectopic beats were compared with the adjacent ectopic-free data. The result showed the frequency indexes after ectopy corrected had less error than other methods with the test of simulated signal and clinical data. It indicated our method could improve the PSD estimation in HRV analysis. The method had advantages of high accuracy and real time properties to recover the sinus node modulation.  相似文献
