The interaction of functional and dysfunctional emotions during balance beam performance     

Cottyn J  De Clercq D  Crombez G  Lenoir M 《Research quarterly for exercise and sport》2012,83(2):300-307

The interaction between functional and dysfunctional emotions, as one of the major tenets of the individual zones of optimal functioning (IZOF) model (Hanin, 2000), was studied in a sport specific setting. Fourteen female gymnasts performed three attempts of a compulsory balance beam routine at three different heights. Heart rate and self-report of functional and dysfunctional emotions were measured during each routine. These data revealed the effectiveness of inducting emotions by manipulating height. Also, performance decreased on the most challenging condition, (i.e., the first attempt on the highest height). Moderated hierarchical regression analysis revealed a significant interaction between functional and dysfunctional emotions only when the dysfunctional emotion level was low.  相似文献   

Environmental innovation and R&D cooperation: Empirical evidence from Spanish manufacturing firms   总被引：2，自引：0，他引：2  

Valentina De Marchi 《Research Policy》2012,41(3):614-623

This paper explores the relationship between firms’ R&D cooperation strategies and their propensity to introduce environmental innovations.Previous literature has supported that environmental innovations differ from other innovations as far as externalities and drivers of their introduction are concerned, highlighting mainly the importance of regulation to trigger them. Using data from the Community Innovation Survey on Spanish manufacturing firms (PITEC), this paper investigates specificities that affect rather how they are developed, and in particular the higher importance of R&D cooperation with external partners.The econometric estimations, controlling for selection bias, suggest that environmental innovative firms cooperate on innovation with external partners to a higher extent than other innovative firms. Furthermore, cooperation with suppliers, KIBS and universities is more relevant than for other innovators, whereas cooperation with clients does not seem to be differentially important. Finally, the results bespoke of a substitution effect between cooperation activities and the internal R&D effort.  相似文献

Effects of preexposure and retention interval placement on latent inhibition and perceptual learning in a choice-maze discrimination task     

De La Casa LG  Timberlake W 《Learning & behavior》2006,34(2):193-201

In two experiments, we examined how preexposure to discriminative stimuli and introduction of a 21-day retention interval affected the latent inhibition (LI) and perceptual learning (PL) of rats in a choice-maze discrimination task. Experimental groups were preexposed to three wall patterns, one in each of three arms of a maze. Control groups were preexposed only to white arms. PL groups were trained to discriminate A versus B, and LI groups, to discriminate A or B versus C. The A and B patterns shared many elements not shared with the C pattern. In Experiment 1, both at the end of training and after the subsequent retention interval, the PL groups performed better than controls, whereas the LI groups performed worse. In Experiment 2, inserting the 21-day retention interval between preexposure and discrimination training disrupted final measures of LI but not PL performance. Implications for current concepts of PL and LI are discussed.  相似文献   

(Ig)noble Lies: Personal Historicism and Richard Mulcaster’s Positions Concerning the Bringing Up of Children (1581)     

Eric De Barros 《Changing English: An International Journal of English Teaching》2013,20(3):317-326

Attempting to push early modern presentism to the radical, logical conclusion of a more personal historicism, this essay draws on a number of interpretive practices and theoretical insights – Stephen Greenblatt’s self-reflectivity, Toni Morrison’s ‘rememory’, Marianne Hirsch’s ‘postmemory’, bell hooks’s ‘passion of experience’, and Linda Charnes’s alternative historicism – to establish the ethical and interpretive significance of my own painful situatedness as an African American man in Renaissance/Early Modern studies. Specifically, I illustrate that significance in a reading of Richard Mulcaster’s Positions Concerning the Bringing Up of Children, a sixteenth-century educational treatise that responds, as I argue, to early modern educational access and social mobility with an insidiously complex, exclusionary admissions policy.  相似文献   

National Assessment of New Standards for Mathematics in Elementary Education in Flanders     

Rianne Janssen  Erik De Corte  Lieven Verschaffel  Evelyn Knoors  Ariane Colémont 《Educational Research and Evaluation》2013,19(2):197-225

A baseline assessment of the new curriculum standards of mathematics for elementary education in Flanders is presented and discussed. A total of 24 measurement scales, each representing a cluster of standards, covered the whole mathematics curriculum. A total of 5,763 6th-grade students participated in the study. Performance on each scale was summarized by estimating the proportion of students who were nonmasters, intermediate, and good masters. Overall, the more innovative curriculum standards were mastered worse. Few gender differences in performance were observed.  相似文献   

Web-based Collaborative Inquiry to Bridge Gaps in Secondary Science Education     

Annelies Raes  Tammy Schellens  Bram De Wever 《学习科学杂志》2013,22(3):316-347

As secondary students’ interest in science is decreasing, schools are faced with the challenging task of providing adequate instruction to engage students—and more particularly the disadvantaged students—to learn science and improve their science inquiry skills. In this respect, the integration of Web-based collaborative inquiry can be seen as a possible answer. However, the differential effects of Web-based inquiry on disadvantaged students have barely been studied. To bridge this gap, this study deals with the implementation of a Web-based inquiry project in 19 secondary classes and focuses specifically on gender, achievement level, and academic track. Multilevel analysis was applied to uncover the effects on knowledge acquisition, inquiry skills, and interest in science. The study provides quantitative evidence not only that a Web-based collaborative inquiry project is an effective approach for science learning, but that this approach can also offer advantages for students who are not typically successful in science or who are not enrolled in a science track. This approach can contribute to narrowing the gap between boys and girls in science and can give low-achieving students and general-track students an opportunity to develop confidence and skills for learning science, bringing them to a performance level that is closer to that of high-achieving students.  相似文献
