On delay-dependent stability conditions for Takagi–Sugeno fuzzy systems     

Fernando O. Souza  Víctor C.S. CamposReinaldo M. Palhares 《Journal of The Franklin Institute》2014

This paper presents new less conservative stability analysis conditions for Takagi–Sugeno fuzzy systems subject to interval time-varying delay. The methodology is based on the direct Lyapunov method allied with an appropriate Lyapunov–Krasovskii functional choice and the use of the integral inequalities, Finsler lemma, Newton–Leibniz formula manipulations and convex combination properties. Particularly, the main result differs from previous ones since the positiveness of the Lyapunov–Krasovskii functional is guaranteed by new relaxed conditions. Two examples illustrate the effectiveness of the proposed methodology.  相似文献

Lexical and sub-lexical effects on accuracy, reaction time and response duration: impaired and typical word and pseudoword reading in a transparent orthography     

Robert Davies  Javier Rodríguez-Ferreiro  Paz Suárez  Fernando Cuetos 《Reading and writing》2013,26(5):721-738

In an opaque orthography like English, phonological coding errors are a prominent feature of dyslexia. In a transparent orthography like Spanish, reading difficulties are characterized by slower reading speed rather than reduced accuracy. In previous research, the reading speed deficit was revealed by asking children to read lists of words. However, speed in list reading sums the time required to prepare an utterance, reaction time (RT), with the time required to say it, response duration (RD). Thus, the dyslexic speed deficit in transparent orthographies could be driven by slow RTs, by slow RDs, or both. The distinction is especially important if developmental readers rely on phonological coding to achieve lexical access because the whole word would have to be encoded before it could be identified. However, while the factors that affect reading RT have been extensively investigated, no attention has been paid to RD. We studied the performance of typically developing and dyslexic Spanish children in an oral reading task. We analysed the impact of word frequency and length on reading accuracy, RT, and RD. We found that accuracy, RT, and RD were affected by word frequency and length for both control and dyslexic readers. We also observed interactions between effects of reader group—dyslexic, typically developing (TD) younger or TD older readers—and effects of lexicality, frequency, and word length. Our results show that children are capable of reading aloud using lexical and sub-lexical coding processes in a transparent orthography.  相似文献   

A Longitudinal Analysis of Gender Differences in Affective Outcomes in Mathematics During Middle and High School   总被引：2，自引：0，他引：2  

Xin Ma  Fernando Cartwright 《School Effectiveness & School Improvement》2013,24(4):413-439

This study examined gender differences in the rate of change in mathematics affect (attitude and anxiety toward mathematics and utility of mathematics) across middle and high school, using data from the Longitudinal Study of American Youth. Hierarchical linear models indicated no gender differences in the rate of decline in either attitude or utility, but females grew faster in anxiety than males. Schools were more responsible for variation in the male than female rate of change in mathematics affect. Student and school variables influenced the rate of change in mathematics affect in a quite different way between males and females.  相似文献   

Let’s begin with ourselves: attempting resonance responses in the exchange of researchers’ professional autobiographies     

Paulo Padilla-Petry  Fernando Hernández-Hernández  Amalia Creus 《课程研究杂志》2013,45(6):819-838

The economic, social, cultural, technological and labour changes experienced by Spanish universities in the last 40?years have had their impact on the professional lives of the university teachers. Our methodological decision to study, through the construction of life histories, how scholars cope with social and institutional changes in their professional lives led us to start by writing our professional autobiographies which were followed by a resonance practice in which each of us wrote a response to a partner’s autobiography. Results show that our responses appeared to have three different functions: give some feedback to our partners, tell our group our position about our partner’s autobiography and make sense of it for us. It became clear that writing about our resonance responses is a difficult task for academics like us and that our texts were bound by the position each one occupied in the research group and at the university. Our experience lets us rethink the interweaving of reflexivity, personal practical knowledge and resonance. The tension between our academic rationality and our efforts to give spontaneous resonance responses shows that even with narrative researchers, changing one’s personal practical knowledge may conflict with a rationalist point of view.  相似文献   

Countercultural Autobiography: Stories From the Underside and Education for Justice     

Fernando A. Cascante-Gómez 《Religious education (Chicago, Ill.)》2013,108(3):279-287

This article describes a countercultural approach to autobiography in comparison with three dominant uses of autobiography in religious education. It defines countercultural autobiographies as stories from the underside of society meant as tools for education for justice and as invitations for transformative dialogue in institutional and societal settings. The article's goal is to invite religious educators, in seminaries and faith communities, to begin a dialogue for finding ways to use countercultural autobiographies to inform theories and practices of religious education that will educate us all in the path of God's vision of justice for the world.  相似文献   

Cognitive-operative model of intelligent learning systems behavior     

Ana Lilia Laureano-Cruces  Javier Ramírez-Rodríguez  Martha Mora-Torres  Fernando de Arriaga  Rafael Escarela-Pérez 《Interactive Learning Environments》2013,21(1):11-38

In this paper behavior during the teaching–learning process is modeled by means of a fuzzy cognitive map. The elements used to model such behavior are part of a generic didactic model, which emphasizes the use of cognitive and operative strategies as part of the student–tutor interaction. Examples of possible initial scenarios for the teaching–learning process are developed, along with the results provided by the model.  相似文献

Acute effects of static and dynamic stretching on hamstrings’ response times     

Francisco Ayala  Mark De Ste Croix  Pilar Sainz de Baranda  Fernando Santonja 《Journal of sports sciences》2013,31(9):817-825

Abstract

The main purposes of this study were to (a) investigate acute effects of static and dynamic lower limb stretching routines on total response time, pre-motor time and motor time of the medial and lateral hamstrings during maximal eccentric isokinetic knee flexion; and (b) determine whether static and dynamic routines elicit similar responses. A total of 38 active adults completed the following intervention protocols in a randomised order on separate days: (a) non-stretching (control condition), (b) static stretching and (c) dynamic stretching. After the stretching or control intervention, total response time, pre-motor time and motor time of the medial and lateral hamstrings were assessed during eccentric knee flexion movements with participants prone. Measures were compared via a mixed-design factorial ANOVA. There were no main effects for total response time, pre-motor time and motor time. The results suggest that dynamic and static stretching has no influence on hamstrings response times (total response time, pre-motor time and motor time) and hence neither form of stretching reduces this primary risk factor for anterior cruciate ligament injury.  相似文献   

The Emergence and Transformations of the World Cup for the Homeless: From the Excitement of Soccer to Managerial Decisions between 2003 and 2012     

Michaël Attali  Fernando Segura M. Trejo  Jonathan Magee 《国际体育史杂志》2013,30(11):1111-1129

Abstract

An international football-soccer tournament was initiated for socially excluded homeless individuals in July 2003 and has been held ever since, growing annually in terms of size, competing delegations, media attention and corporate involvement. The aim of the paper is to analyze the initial, historical, journey of this World Cup from its conceptual formation until the end of its first decade (2003–2012). The paper looks particularly at the efforts involved in bringing the concept to life and the challenges the organizers faced before achieving the annual frequency of an event dedicated for wider social purposes. However, also discussed is the use of competitive football formats and the organization of the competition for male and female players. As the tournament has become more successful, it is argued that its overall aim of proposing tools beyond sport for homeless people has been displaced in certain ways. The management orientations, the focus on the trophies, images of excitement, and the corporate agendas have brought sensitive contradictions to its principles of inclusion.  相似文献
