Investigating the double-deficit hypothesis of developmental dyslexia in an orthography of intermediate depth

The present study aimed to investigate the double-deficit hypothesis (DDH) in an orthography of intermediate depth. Eighty-five European Portuguese-speaking children with developmental dyslexia, aged 7 to 12, were tested on measures of phonological awareness (PA), naming speed (NS), reading, and spelling. The results indicated that PA and NS were not significantly correlated, and that NS predicts reading fluency (but not reading accuracy and spelling) beyond what is accounted for by PA. Although the majority of the children with developmental dyslexia have double deficit (62.4%), some children have a single phonological deficit (24.7%) or a single NS deficit (8.2%). Children with a double deficit were not more impaired in reading fluency, reading accuracy, and spelling than both single-deficit subtypes. In conclusion, the findings of the present study are partially consistent with the DDH and provide evidence for the multifactorial model of developmental dyslexia. Implications of the DDH for an orthography of intermediate depth are emphasized.

     

To learn and to construct knowledge in the context of work with adult education: a Portuguese case study

Work contexts are frequently referred to as spaces of learning and production of individual and/or collective knowledge. In such contexts specific dynamics are developed which cause the processes of learning and of knowledge production to have particularities. This paper aims at accounting for some dynamics that are associated with those processes, based on the main results of an ethnographic study on the adult educator team of a Portuguese local development association. The research identified ways of working/action rules based on the learning and knowledge production processes in the association. Mutual help, the reformulation and collectivization of practice, reflection in and about the action, and the negotiation of meaning about the practice are some of the mechanisms identified. The study also highlights how those dynamics of knowledge and learning and ways of doing may contribute to a practice which is closer to the needs of the adults to whom this team offers its education and training services.     

Towards an understanding of technical change in semi-industrialized countries

Contrary to canventional wisdom, semi-industrialized countries engage, to an appreciable extent, in R&D activities leading to technical change. Much of their technical change activity consists of adaptation of foreign technology to local inputs and market preferences, and is carried out in response to contraints and distortions prevailing in their economies. Moreover, in this context, limited consideration is given to cost reduction, since the main objective is to manufacture under protection and technical change becomes a complementary response to the productive effort.A key factor in the ability to engage in such technical change activities is the availability of technically competent manpower, including scientists, engineers and technicians. At the same time, previous investment in the formation of such technical skills may result in an “excessive” supply of skilled labor, which , coupled with import constraints, will induce eexcessive adaptation of machinery and equipment and may deter from the importaion of new technology embodied in such equipment. Conversely, a pronounced scarcity of technicl skills may impade the adaptation of technology and result in excessive importantion of machinery and limit local efforts of modification, adaptation, etc.Because of the eay technical change is generated, it does not necessarily follow that it is all cases beneficial to the national economies of the countries in which it takes place. However, proper cost benefit accounting of the social returns to technical change activities is complicated by the intractable nature of many of the indirect and secondary effects, like learning from the R&D, or the impact of adaptation to domestic inputs in the development of local suppliers, etc. Also, th interdependencies between technical change and production and between various technical change activities are little understood.conventionall economic theory has contributed little to the understanding of the technical development process. The analysis of technical change in terms of the market failure metaphor, while providing useful insights, is also not very as far as understanding the problem of not very helpful as far as understanding the problem of technical change in semi-industrialized countries is concerned, since the roles of uncertainty and externalities in that situation are quite different from those foreseen in the market failure analysis for industrializerd countries. Special attention should be given to the possible application of the metaphor in trying to improve our understanding of the problems arising in the use of technical information and not only its creation. This would be particularly helpful in connection with the technical development problems of small enterprises not enjoying the benefits of the devesion of labor which are possible in larger firms.     

Playing with Our Friends and Making Money: Real Madrid FC’s Economic Model and the Impact of International Friendly Matches, 1955–1963

This paper analyzes how Real Madrid Football Club took advantage of the enormous international prestige that they gained thanks to their victories in the first five editions of the European Champion Clubs’ Cup (between 1956 and 1960) to arrange a large number of international friendly matches that generated great income. Real Madrid created a new strategy by means of friendly matches and international tours that favoured an economic model centred on signing the best players of the day, as a way to attract fans to their stadium and to achieve new victories. Having access to the documentation of the Real Madrid archive has allowed the author to rely on primary sources which support these arguments, sources that hitherto had not been used. In the same way, this research demonstrates the important economic benefits that this activity brought to the Franco dictatorship.

How education background affects design outcome: teaching product development to mechanical engineers,industrial designers and managers

ABSTRACT

Product design and development (PDD) is a current topic of academic and industrial research. Emphasis on innovation and entrepreneurship, as well as design thinking and creativity has been recently pulled together into the teaching and research on PDD. This paper looks into a multidisciplinary setting made up of three similar but independent PDD masters courses taught at three higher education institutions, having the same assessment, syllabus, assignments and outcomes. As expected, students’ projects foci are different. The outcomes of this experience were confronted with an ex-post literature review, which generated thorough guidelines that supported an innovative proposal for PDD education, to be implemented into an interdisciplinary Summer School. Significant generalisable contributions for educating modern engineers, designers and business entrepreneurs are expected, instead of just teaching methods of engineering, design and entrepreneurship at the case universities. The limitation of the used inductive reasoning concerns ‘truth’ being suggested but not assured.     

The impact of a Curriculum for Resilience Promotion in Deaf Children and Adolescents

Resilience is an interactive process involving internal skills that should be promoted, especially in the early stages of development. This study aims to adapt and implement two themes from the European Curriculum for Resilience Promotion – RESCUR, namely, ‘Developing Communication Skills’ and ‘Establishing and Maintaining Healthy Relationships’, for deaf and hard-of-hearing (DHH) students. The study included 37 children and adolescents from three Portuguese regions and its impact was evaluated through the perspectives of the students, their guardians and their teachers. Each 90-minute session was implemented weekly. The sessions followed the RESCUR curriculum structure with necessary adaptations to the mindfulness activities, stories, role-play and worksheets. The mean scores increased from pre- to post-intervention assessment on all instruments, namely, KIDSCREEN-10 (children/adolescents), KIDSCREEN-10 (guardians) and CYRM-28 (teachers). The implementation of adapted curricula promoting resilience seems to be beneficial to DHH children, allowing the development of specific resilience-associated skills, and thus enhancing health, well-being and quality of life.     

Mentors and teachers: testing the effectiveness of simultaneous roles on school performance from a basic psychological needs perspective

The mentor’s background in educational roles has been presented as a moderator of School-Based Mentoring (SBM). However, the analysis of overlapping mentoring and teaching roles has been underemphasized in the literature. The aim of this study is to test whether the combination of mentoring and teaching roles influences the mentees’ school performance, within a Portuguese SBM program. A three-stage experimental study was conducted in order to compare mentored (n = 157) and non-mentored students (n = 160) enrolled in formal basic education (5th to 8th grades). Multivariate Analyses of Covariance (MANCOVA) revealed that the combination of mentoring and teaching roles was effective in reducing the mentees’ unexcused absences and in improving their grades in Portuguese language and math as well as their Grade Point Average (GPA) compared to equivalent non-mentored students. Further analyses demonstrated that an increased satisfaction of the mentored students Basic Psychological Needs (BPN) promoted better school performance outcomes when compared with non-mentored students with an identical perception of BPN support. However, mentored students that experienced an increased satisfaction of BPN had marginally significantly worse Grade Point Average (GPA) than the mentored students that perceived less or similar BPN support within SBM. These mixed trends are discussed and recommendations are made for a more balanced support of BPN in SBM relationships and across the different relationships held between the mentees and other teachers, in order to foster an improvement of school performance.
