A importância das tecnologias da informação e da comunicação em crianças com autismo ; no pré-escolar

O presente estudo teve como objetivo aferir a importância das Novas tecnologias da Informação em crianças com autismo, no Pré-Escolar. Para um conhecimento mais alargado do tema e uma nova visão sobre esta problemática, foi necessário recorrer a uma análise da literatura, definindo-se no enquadramento teórico uma abordagem à Educação Especial, Autismo e às Novas Tecnologias da Informação, procurando identificar os recursos educativos na área das Novas Tecnologias, utilizados nestas crianças, que as ajudem a minimizar e superar dificuldades, tornando-as competentes e funcionais levando à inclusão no meio ambiente, social e escolar. Apresentou-se a metodologia utilizada; metodologia qualitativa e quantitativa, a definição da amostra; Educadores de Infância e Professores do Ensino Especial; o inquérito por questionário como instrumento de recolha de dados para perspetivar a opinião dos Educadores e Professores do Ensino Especial sobre a importância das Tic no processo ensino/aprendizagem. Por fim fez-se a análise e discussão dos resultados através dos quais se concluiu que, os Educadores de Infância têm bastante desconhecimento sobre o autismo e as TIC; já a maioria dos Professores do Ensino Especial têm mais conhecimento sobre o tema, reconhecendo ambos os grupos de inquiridos, a importância das TIC no processo ensino/aprendizagem dos indivíduos autistas.

The importance of local museums in Portugal

The widening of the notion of heritage and the consequent redefinition of the “museological object”, the idea of community participation in the definition and management of the museological practice, museology as a development factor, the issues of interdisciplinarity, the use of “new technologies” of information and museography as an autonomous communications means, are examples of issues resulting from contemporary museological practices. If indeed museology in Portugal intends to continue to participate in international museology’s renovation process, it is evident that it must adequately (re)think theoretical and practical museology so as to meet the new demands…

Phylogenies reveal new interpretation of speciation and the Red Queen

The Red Queen metaphor has species accumulating small changes to keep up with a continually changing environment, with speciation occurring at a constant rate. This constant-rate claim is now tested against four competing models, using 101 phylogenies of animal, plant and fungal taxa. The results provide a new interpretation of the Red Queen; a view linking speciation to rare stochastic events that cause reproductive isolation.

Research review: reading comprehension in developmental disorders of language and communication

Background: Deficits in reading airment (SLI), Down syndrome (DS) and autism spectrum disorders (ASD). Methods: In this review (based on a search of the ISI Web of Knowledge database to 2011), the Simple View of Reading is used as a framework for considering reading comprehension in these groups. Conclusions: There is substantial evidence for reading comprehension impairments in SLI and growing evidence that weaknesses in this domain are common in DS and ASD. Further, in these groups reading comprehension is typically more impaired than word recognition. However, there is also evidence that some children and adolescents with DS, ASD and a history of SLI develop reading comprehension and word recognition skills at or above the age appropriate level. This review of the literature indicates that factors including word recognition, oral language, nonverbal ability and working memory may explain reading comprehension difficulties in SLI, DS and ASD. In addition, it highlights methodological issues, implications of poor reading comprehension and fruitful areas for future research.

An introduction to the ‘new’ politics of agriculture and food

The agricultural policy agenda has been broadened with farm policy issues now interlinking with other policy domains (food safety, energy supplies, environmental protection, development aid, etc.). New actors promoting values which sometimes conflict, or which are not always easily reconcilable, with those previously guiding agricultural policy have entered the broader agricultural and food policy domain. The studies of various new policy issues inter-linking with the agricultural policy domain included in this special issue show that value conflicts are addressed in different ways and thus result in inter-institutional coordination and conflict unfolding differently. Studies of inter-institutional policy making in the agricultural policy sector have the potential to contribute to theoretical developments in public policy analysis in much the same way as agricultural policy studies did in the past.

Phylogenetic Validation of the Genera Angomonas and Strigomonas of Trypanosomatids Harboring Bacterial Endosymbionts with the Description of New Species of Trypanosomatids and of Proteobacterial Symbionts

We comparatively examined the nutritional, molecular and optical and electron microscopical characteristics of reference species and new isolates of trypanosomatids harboring bacterial endosymbionts. Sequencing of the V7V8 region of the small subunit of the ribosomal RNA (SSU rRNA) gene distinguished six major genotypes among the 13 isolates examined. The entire sequences of the SSU rRNA and glycosomal glyceraldehyde phosphate dehydrogenase (gGAPDH) genes were obtained for phylogenetic analyses. In the resulting phylogenetic trees, the symbiont-harboring species clustered as a major clade comprising two subclades that corresponded to the proposed genera Angomonas and Strigomonas. The genus Angomonas comprised 10 flagellates including former Crithidia deanei and C. desouzai plus a new species. The genus Strigomonas included former Crithidia oncopelti and Blastocrithidia cuiicis plus a new species. Sequences from the internal transcribed spacer of ribosomal DNA (ITS rDNA) and size polymorphism of kinetoplast DNA (kDNA) minicircles revealed considerable genetic heterogeneity within the genera Angomonas and Strigomonas. Phylogenetic analyses based on 16S rDNA and ITS rDNA sequences demonstrated that all of the endosymbionts belonged to the Betaproteobacteria and revealed three new species. The congruence of the phylogenetic trees of trypanosomatids and their symbionts support a co-divergent host-symbiont evolutionary history. (C) 2011 Elsevier GmbH. All rights reserved.

A interação nas distâncias: a análise de um processo

Education and technology have always walked side by side. The Information and Communication Technologies are inserted in education as a profile of people from the new era. This research has the objective of understanding the insertion of the use of the Technologies of Information and Communication within the educational context, from the analysis of the process of interactivity among students and teachers of the Portuguese distance course of the Tiradentes University (Unit). For such, the empiric investigation was based on the analysis of academic documents, such as: the Course Pedagogical Project and Class Planning of regular classes, in regular classrooms, as well as interviews, focal groups, and pictures with people who live the history of the course. Direct observations were also conducted. The methodology applied was bibliographic and qualitative research of the exploratory type, using the information that was collected through the interviews. The results of this research demonstrated that the interaction promoted by the ICT represents a process of social change, and therefore, of development for education. It was concluded that the Distance Education has to overcome some fragilities, aiming at contributing to the educational field and to the promotion of interactions among students
