I’m still learning. A web platform for the intervention in reading disabilities

In 2014, 20% of the 4th graders had an unsatisfactory evaluation in the national exam of Portuguese language. This percentage is similar in the 6th and 9th grades indicating that a large number of Portuguese students have reading difficulties. The e-learning platform “I’m still learning” was developed to provide a systematic intervention with students (from 1st to 4th grade) experiencing reading difficulties. This free access platform provides a set of didactic sequences to promote phonological awareness, word reading, reading fluency and comprehension. Informal tasks for reading assessment are also included. In this paper we describe the platform and the theoretical framework adopted in its construction.info:eu-repo/semantics/publishedVersio

Trematode Diversity in Freshwater Fishes of the Globe II: “New World”

We provide a summary overview of the diversity of trematode parasites in freshwater fishes of the “New World,” i.e. the Americas, with emphasis on adult forms. The trematode fauna of three regions, South America, Middle America, and USA and Canada (North America north of Mexico), are considered separately. In total, 462 trematode species have been reported as adults from the Americas. The proportion of host species examined for parasites varies widely across the Americas, from a high of 45% in the Mexican region of Middle America to less than 5% in South America. North and South America share no adult species, and one exclusively freshwater genus, Creptotrema Travassos, Artigas & Pereira, 1928 in the Allocreadiidae Looss, 1902 is the most widely distributed. Metacercariae of strigeiforms maturing in fish-eating birds (e.g., species of the Diplostomidae Poirier, 1886) are common and widely distributed. The review also highlights the paucity of known life-cycles. The foreseeable future of diversity studies belongs to integrative approaches and the application of molecular ecological methods. While opportunistic sampling will remain important in describing and cataloguing the trematode fauna, a better understanding of trematode diversity and biology will also depend on strategic sampling throughout the Americas

Parent's reports of lexical and grammatical aspects of toddlers's language in European Portuguese: developmental trends, age and gender differences

The results from a large-scale study on toddlers’ language acquisition in European Portuguese are presented. Toddlers’ lexical and grammatical competencies were assessed using the MacArthur–Bates Communicative Development Inventory: Words and Sentences. The results, based on 3012 reports completed by parents, indicate an increase in the lexical size and on five measures of grammatical development (production of regular morphology, irregular morphology, over-regularizations, mean length of utterances and sentence complexity) across age groups. A main effect of gender was found for lexical size, production of regular and irregular morphology, production of over-regularizations and sentence complexity, with girls obtaining overall higher scores than boys. All lexical and grammatical development measures are positively correlated, even after controlling for age and gender effects. These findings are discussed in terms of their consistency with those obtained for other languages.CiPsi - Psychology Research Centre, Uminho (UID/PSI/ 01662/2013), PortugalCIEC – Research Centre on Child Studies, IE, UMinho (FCT R&D unit 317), Portugalinfo:eu-repo/semantics/publishedVersio

Biochemical and microbiological analysis of the saliva of institutionalized elderly : with edentulism, use of dentures and presence of biofilm

To analyze biochemical and microbiological parameters of the saliva of institutionalized elders and to investigate the relation of these parameters with edentulism, use of dentures and presence of biofilm. A cross-sectional study carried was out in seven long-term institutions. Samples (n=161) of unstimulated saliva were collected for analysis of salivary flow, quantification of total proteins and identification of microorganisms. Oral examination was carried out to verify the number of missing teeth, the use of dentures and the presence of visible biofilm on the surface of teeth and dentures. Associations were performed using chi-square or Fisher?s exact test (?0.05). Associations were observed between the presence of dentures biofilm and the colonization of Streptococcus sp. (p=0.038) and Candida sp. (p=0.03). The absence of teeth and use of dentures do not influence the amount of total proteins and the microorganisms count in saliva. Denture biofilms are associated with the presence of Streptococcus sp. and Candida sp. in saliva of institutionalized elders

Lexical, morphological and syntactic development in toddlers between 16 and 30 months old: a comparison across European Portuguese and Galician

The main aims of this study were to investigate the relationship between the lexical size and the emergence of morphological and syntactic markers in toddlers between the ages of 16 and 30 months and to compare these results between Galician and European Portuguese. Parents of 3012 Portuguese toddlers and those of 1081 Galician toddlers completed the MacArthur–Bates Communicative Development Inventory: Words and Sentences. The results indicated that the number of words, the ability to combine words and the number of different morphemes produced increased with age. The ability to combine words was used as an indicator of syntactic development; this ability was also associated with the toddlers’ lexical size. In both samples, gender morphemes seemed to be the first to have their production generalized, followed by the plural and the past participle. The production of gender morphemes was accompanied by a small lexical size, whereas the imperfect tense and the person mark onset were associated with large lexical sizes. The implications of these results for charting the continuity between lexical, morphological and syntactical development are discussed.CiPsi - Psychology Research Centre, Uminho (UID/PSI/ 01662/2013), Portugal.

Online and print newspapers in Europe in 2003. Evolving towards complementarity

This article assesses online newspapers in Europe from a media evolutionary perspective, ten years after the introduction of the World Wide Web. Comparing print and online front pages of 51 newspapers in 14 countries in 2003, we argue that online newspapers complement print newspapers in modest ways. Online, publishers put more emphasis on service information, offer additional news items, that nonetheless report on similar topics in similar ways, and add personal interactivity, content selectivity and realtime news to the print news offering. One subset of online newspapers charges for services, and offers more content and personal interactivity. Another, partly overlapping subset offers more original news; in a short and anonymous format. Overall, however, online newspapers in Europe make up a heterogeneous group, suggesting that online newspapers still have to find their definite form and role in the European news market

Promover a fluência em leitura: um estudo com alunos do 2º ano de escolaridade

Neste artigo são analisados os resultados de um Programa de Promoção da Fluência em Leitura (PPFL), implementado junto de 74 alunos do 2º ano de escolaridade de um Agrupamento Escolar do norte de Portugal. O PPFL é constituído por 22 sequências didáticas, elaboradas a partir de 22 textos (9 narrativos, 4 informativos e 9 poemas). Cada sequência foi operacionalizada em sessões de 10 a 15 minutos, durante 22 semanas, em ciclos de cinco dias (quinta-feira a quarta-feira). Em cada semana foi trabalhado apenas uma sequência didáctica (i.e. um texto). Foi utilizado um design quase experimental, com grupo experimental e grupo de controlo e com pré e pós-teste. Os sujeitos foram avaliados através de um teste de fluência de leitura – o Teste de Fluência em Leitura (TFL) –, considerando as variáveis velocidade e precisão. Os resultados evidenciam diferenças significativas a favor do grupo experimental, que superou as diferenças iniciais que se registavam no pré-teste. A análise qualitativa do impacto do PPFL aponta para um incremento na motivação para ler, no envolvimento da família e para a mudança de práticas por parte dos professores envolvidos.CIEC - Centro de Investigação em Estudos da Criança, IE, UMinho (UI 317 da FCT), PortugalFundos Nacionais através da FCT (Fundação para a Ciência e a Tecnologia) e cofinanciado pelo Fundo Europeu de Desenvolvimento Regional (FEDER) através do COMPETE 2020 – Programa Operacional Competitividade e Internacionalização (POCI) no âmbito do CIEC (Centro de Investigação em Estudos da Criança, da Universidade do Minho) com a referência POCI-01-0145-FEDER-00756

The ocean sampling day consortium

Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of the marine microbial biodiversity and function of the world’s oceans. It is a simultaneous global mega-sequencing campaign aiming to generate the largest standardized microbial data set in a single day. This will be achievable only through the coordinated efforts of an Ocean Sampling Day Consortium, supportive partnerships and networks between sites. This commentary outlines the establishment, function and aims of the Consortium and describes our vision for a sustainable study of marine microbial communities and their embedded functional traits
