Who is willing to pay for science? On the relationship between public perception of science and the attitude to public funding of science     

Muñoz A  Moreno C  Luján JL 《Public understanding of science (Bristol, England)》2012,21(2):242-253

This article examines the relationship between the general public's understanding of science and the attitude towards public funding of scientific research. It applies a multivariate and discriminant analysis (Wilks' Lambda), in addition to a more commonly used bivariate analysis (Cramer's V), to data compiled from the Third National Survey on the Social Perception of Science and Technology in Spain (FECYT, 2006). The general conclusion is that the multivariate analysis produces information complementary to the bivariate analysis, and that the variables commonly applied in public perception studies have limited predictive value with respect to the attitude towards public funding of scientific research.  相似文献   

Dissipative observers for discrete-time nonlinear systems     

Jesús D. Avilés  Jaime A. Moreno 《Journal of The Franklin Institute》2018,355(13):5759-5770

This paper addresses the problem of designing a state observer for a class of nonlinear discrete-time systems using the dissipativity theory. We show that the dissipative observation methodology, originally proposed by one of the authors for continuous-time nonlinear systems, can be extended to the discrete-time case. For constructing a convergent observer, the methodology is applied to the nonlinear estimation error dynamics, which is decomposed into a discrete-time Linear Time-Invariant (LTI) subsystem in the forward loop, connected to a time-varying static nonlinearity in the feedback loop. In order to assure asymptotic stability of the closed-loop, complementary dissipativity conditions are imposed on each of the subsystems: (i) the static nonlinearity is required to be dissipative with respect to a quadratic supply rate, and (ii) the observer gains are designed such that the LTI system is dissipative with respect to a complementary supply rate. As in the continuous time framework, the proposed method includes as special cases, unifies and generalizes some observer design methods proposed previously in the literature. A great advantage of the Dissipative Observer Design Method proposed here is that it leads to Matrix Inequalities for the design of the observer gains, and these can be usually converted into Linear Matrix Inequalities (LMI’s). The results are illustrated using Chua’s Chaotic system.  相似文献   

An intervention program for promoting deaf pupils' achievement in mathematics     

Nunes T  Moreno C 《Journal of deaf studies and deaf education》2002,7(2):120-133

Our past research identified two aspects of deaf children's functioning that places them at risk for underachievement in mathematics. The first is their reduced opportunities for incidental learning, and the second is their difficulty in making inferences involving time sequences. This article examines the effectiveness of an intervention program to promote deaf children's numeracy that was designed to deal with these two factors. The design involved a comparison of 23 deaf pupils participating in the project with a baseline group formed by 65 deaf pupils attending the same schools in the previous year. The project pupils were tested before and after the intervention on the NFER-Nelson Age Appropriate Mathematics Achievement Test. The intervention was delivered by the teachers during the time normally scheduled for mathematics lessons. The project pupils did not differ from the baseline group at pretest but performed significantly better at posttest. They also performed at posttest better than expected on the basis of their pretest scores, according to norms provided by the NFER-Nelson Age Appropriate Mathematics Test for assessing the progress of hearing pupils. We conclude that the program was effective in promoting deaf pupils' achievement in numeracy.  相似文献

Decreasing Cognitive Load for Novice Students: Effects of Explanatory versus Corrective Feedback in Discovery-Based Multimedia   总被引：1，自引：0，他引：1  

Moreno  Roxana 《Instructional Science》2004,32(1-2):99-113

This paper examines one of the potentialroles that software agents may have inhelping students reduce working memoryload while learning from discovery-basedmultimedia environments: providingexplanatory feedback. Two studiesexamined the guided feedbackhypothesis according to which, discoverylearning environments that use explanatoryfeedback (EF) to guide novice students inthe process of meaning making promotedeeper learning than those that presentidentical materials using correctivefeedback (CF) alone. In both experiments,the EF group produced higher transferscores, rated the computer game as morehelpful, and gave comparable interest andmotivation ratings than the CF group. Mental load rating scales providedevidence in both experiments that EF waseffective due to reductions in cognitiveload. Results support the use of agentguidance in the form of EF for novicestudents who learn with discovery-basedmultimedia games.  相似文献

How speechreading contributes to reading in a transparent ortography: the case of Spanish deaf people          下载免费PDF全文

Isabel R. Rodríguez‐Ortiz  David Saldaña  Francisco J. Moreno‐Perez 《Journal of Research in Reading》2017,40(1):75-90

The aim of the study is to describe the performance of deaf and hearing people while speechreading Spanish, a language with transparent orthography, and to relate this skill to reading efficiency. Three groups of 27 participants each were recruited: a group of deaf participants, a chronological age‐matched hearing group and a reading age‐matched hearing group. All three were tested on vocabulary, phonological awareness, reading speed, speechreading and, only in the group of deaf people, speech intelligibility. The results indicate that deaf people are better speechreaders than younger hearing people, but they are no better than their age‐matched peers, and that speechreading is related to reading only in deaf people.  相似文献   

Drug education in bolivian schools: A feasibility study for cross-cultural application of a preventive curricular unit     

Gerardo M. Gonzalez  Veronica Kaune Moreno 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》1995,41(6):439-458

The purpose of this study was to test the feasibility of adapting and implementing in La Paz, Bolivia a drug education course originally developed for use in the middle schools in the United States. On the basis of teacher and student evaluations, it was concluded that the unit is a viable, culturally relevant and effective method of drug education in the public and private schools in La Paz. Implications for the prevention of other health-related problems and for implementation of a demandreduction strategy to prevent drug abuse throughout the Americas are discussed.
