Cinema Demand in Spain: A Cointegration Analysis

In this paper we explain the decline in cinema attendance in Spain since 1968. We use a cointegration analysis to estimate an individual demand function for cinema, with annual data and in terms of average attendance per inhabitant. We find that cinema is a luxury good and that its demand is elastic with respect to its price. We also show that television acts as a deterrent with regard to cinema attendance.

Cross-over, thresholds, and interactions between science and technology: lessons for less-developed countries

Presently, science is an important precondition for the economic development of less-developed countries. This paper discusses the specific roles that science has at initial stages of development, pointing to its contributions for the countries’ absorptive capability. Furthermore, this paper specifies the role of science for initiating a positive interaction with technological development, since initial stages of development and during catching up processes. For less-developed countries, neither the linear model of technology nor an “inverted linear model” would take place: a more interactive approach is necessary for development. Using statistics of patents (USPTO) and scientific papers (ISI) for 120 countries (1974, 1982, 1990, and 1998), this paper analyses some evidences on thresholds levels of scientific production to originate an interactive relationship between science and technology. These data also document that the value of this threshold seems to double from one period to another. Although this paper presents tentative results, some policy implications are discussed: scientific institutional building must be seen as a component of modern industrial policies.     

Do Consonant Sonority and Status Influence Syllable-Based Segmentation Strategies in a Visual Letter Detection Task? Developmental Evidence in French Children

This article queries whether consonant sonority (sonorant vs. obstruent) and status (coda vs. onset) within intervocalic clusters influence syllable-based segmentation strategies. We used a modified version of the illusory conjunction paradigm to test whether French beginning, intermediate, and advanced readers were sensitive to an optimal “sonorant coda–obstruent onset” sonority profile within the syllable boundaries as a cue for a syllable-based segmentation. Data showed that children used a syllable-based segmentation that improved with reading skills and age. The results are discussed to support that the visual letter detection within pseudowords primarily and early relies on acoustic-phonetic cues within the syllable boundaries, whereas the syllable effect seems to be developmentally constrained by reading skills and age.     

Evaluating the teaching and learning experience for the child with dyslexia in special and mainstream settings in Ireland

This study examines and evaluates special provision for pupils with dyslexia in three different settings: reading schools, reading units and mainstream support. The research focused on the teaching and learning context for pupils with dyslexia, the support teacher, the mainstream teacher and the experience of the student. The main participants were teachers and tutors supporting pupils with dyslexia, and the parents of these children. Survey methods included questionnaires, focus group discussions, interviews and quantitative data on pupils' reading attainment. In addition, a total of six schools, two representing each model of support, were selected as case studies. This article reports part of a larger survey, which evaluated the effectiveness of three models of special provision for children with dyslexia in primary school. The study shows that there are academic and social benefits for the child with dyslexia who is enrolled in a special setting. However, placement in a reading school or reading unit per se does not guarantee that a child will ‘catch up’ with his or her peers. The findings reported a similarity in the methods and practices teachers use in both mainstream and special settings. The discussion suggests that if teachers are to ‘catch them before they fall’ there are serious questions that must be asked about how we are teaching basic literacy skills. The findings suggest an urgent need for a more balanced approach to teaching reading and writing.     

Secondary students’ modelling conceptualisation in situations related to particle dynamics: a clinical perspective

This study investigates the modelling conceptualisation of secondary school students in two situations related to particle dynamics: pendulum’s motion and horizontal motion. We performed in-depth clinical interviews with secondary school students (N?=?10). Participants’ ideas about properties which are not ‘given’ in empirical observations were explored in order to investigate signs of abstractions and idealisations in their reasoning processes. We proposed contributions to modelling in science education based on Mario Bunge’s epistemology and we employed his basic concepts as the axis to analyse our results: (1) abstractions and idealisations, considered as thought processes required to build conceptual counterparts of concrete objects; (2) theoretical models, meaning hypothetico-deductive systems concerning those conceptual objects; and (3) general theoretical frameworks that allow us to derive those theoretical models. We developed our analysis viewing the ideas presented by participants as concepts-in-action and theorems-in-action as regarded by Gérard Vergnaud’s Theory of Conceptual Fields. Results indicated a gradation in the concepts-in-action mobilised in terms of levels of idealisation and showed that participants do not spontaneously recognise the use of a general theory as a possible way to obtain a theoretical model. These results suggest that science education practices must pay better attention to make abstractions and idealisations explicit in scientific concepts formation, as well as to the heuristic role of theories in model construction.
