Reading performance in children with visual function anomalies

Aims - To compare reading performance in children with and without visual function anomalies and identify the influence of abnormal visual function and other variables in reading ability. Methods - A cross-sectional study was carried in 110 children of school age (6-11 years) with Abnormal Visual Function (AVF) and 562 children with Normal Visual Function (NVF). An orthoptic assessment (visual acuity, ocular alignment, near point of convergence and accommodation, stereopsis and vergences) and autorefraction was carried out. Oral reading was analyzed (list of 34 words). Number of errors, accuracy (percentage of success) and reading speed (words per minute - wpm) were used as reading indicators. Sociodemographic information from parents (n=670) and teachers (n=34) was obtained. Results - Children with AVF had a higher number of errors (AVF=3.00 errors; NVF=1.00 errors; p<0.001), a lower accuracy (AVF=91.18%; NVF=97.06%; p<0.001) and reading speed (AVF=24.71 wpm; NVF=27.39 wpm; p=0.007). Reading speed in the 3rd school grade was not statistically different between the two groups (AVF=31.41 wpm; NVF=32.54 wpm; p=0.113). Children with uncorrected hyperopia (p=0.003) and astigmatism (p=0.019) had worst reading performance. Children in 2nd, 3rd, or 4th grades presented a lower risk of having reading impairment when compared with the 1st grade. Conclusion - Children with AVF had reading impairment in the first school grade. It seems that reading abilities have a wide variation and this disparity lessens in older children. The slow reading characteristics of the children with AVF are similar to dyslexic children, which suggest the need for an eye evaluation before classifying the children as dyslexic.

Preparação para a performance instrumental: problemáticas e estratégias: relatório de estágio

Resumo I (Prática Pedagógica) - Nesta seção do relatório de estágio pretende-se caraterizar e apresentar todos os elementos referentes à prática pedagógica, que fizeram parte do estágio do ensino especializado da música, realizado na Escola de Música do Orfeão de Leiria no ano letivo de 2013/2014. De uma forma geral, o relatório de estágio pretende colocar em evidência aspetos pedagógicos como metodologias de ensino, questões motivacionais, estilos de aprendizagem, entre outros. Durante um ano letivo completo foram analisados, com especial atenção, três alunos que foram envolvidos no estágio, construindo e modelando os seus processos de aprendizagem. Para cada um deles foi realizado, ao longo do ano letivo, 30 planos de aula, uma planificação anual e três gravações vídeo/áudio em contexto de aula. Não foi uma tarefa nada fácil de realizar, mas que trouxe inúmeros conhecimentos não só de caráter pedagógico mas também de caráter pessoal. A parte inicial desta seção será dedicada à descrição e caraterização da escola onde foi realizado o estágio, a Escola de Música do Orfeão de Leiria/Conservatório de Artes. Será feita uma pequena abordagem histórica da instituição, bem como do seu projeto educativo, dacomunidade escolar, do seu contexto sociocultural e da classe de saxofone. Será apresentada também uma caraterização dos alunos, segundo vários parâmetros. Posteriormente, serão descritas algumas das práticas educativas desenvolvidas, com os alunos, em contexto de estágio. Para tal, serão utilizados como instrumentos, não só a experiência ativa do docente/estagiário, mas também todas as gravações, planos de aulas e planificações anuais, realizados em contexto de estágio do ensino especializado. Por fim, será realizada uma reflexão crítica do desempenho como docente de saxofone no âmbito do estágio e uma conclusão de toda a seção da prática pedagógica.

Alice's anima or the obligation of a reading transliteracy

This paper suggests an analysis of "Inanimate Alice" by Kate Pullinger, Chris Joseph and Ian Harper as an example of a transmedia narrative that triggers a new reading experience whilst proposing a literary alterity between reading and performance. Narrative experiences that elect the visual plasticity, interchanging games and tactility as drivers of the creative process are not new. Yet, narrative experiences, which have been created in the gap between reality and fiction, have found on the digital realm the perfect environment to multiple hybrid experiences. Bearing in mind Walter Benjamin’s concept of Erlebnis and Erfahrung, a critical analysis of this digital fiction tries to illustrate how literary art finds its space and time in a metamorphosed continuum only activated by the “patient reader”. All the multimedia hybrids, which this digital literary work may have, challenge readers to interpret different signals and poetic structures that most of readers might not be accustomed to; however even among a cognitive dissonance, meaning is found and reading happens only if time, space and attention are available. All possible transmedia literacies can only respond to this experience of online reading, if they are able to focus and draw attention not to a simple new behaviour or a single new practice, but to a demanding state of affairs that assemble different objective and subjective value forms.

Effects of early life permethrin exposure on spatial working memory and on monoamine levels in different brain areas of pre-senescent rats

Pesticide exposure during brain development could represent an important risk factor for the onset of neurodegenerative diseases. Previous studies investigated the effect of permethrin (PERM) administered at 34 mg/kg, a dose close to the no observable adverse effect level (NOAEL) from post natal day (PND) 6 to PND 21 in rats. Despite the PERM dose did not elicited overt signs of toxicity (i.e. normal body weight gain curve), it was able to induce striatal neurodegeneration (dopamine and Nurr1 reduction, and lipid peroxidation increase). The present study was designed to characterize the cognitive deficits in the current animal model. When during late adulthood PERM treated rats were tested for spatial working memory performances in a T-maze-rewarded alternation task they took longer to choose for the correct arm in comparison to age matched controls. No differences between groups were found in anxiety-like state, locomotor activity, feeding behavior and spatial orientation task. Our findings showing a selective effect of PERM treatment on the T-maze task point to an involvement of frontal cortico-striatal circuitry rather than to a role for the hippocampus. The predominant disturbances concern the dopamine (DA) depletion in the striatum and, the serotonin (5-HT) and noradrenaline (NE) unbalance together with a hypometabolic state in the medial prefrontal cortex area. In the hippocampus, an increase of NE and a decrease of DA were observed in PERM treated rats as compared to controls. The concentration of the most representative marker for pyrethroid exposure (3-phenoxybenzoic acid) measured in the urine of rodents 12 h after the last treatment was 41.50 µ/L and it was completely eliminated after 96 h.

The presence of Taeniodonta (Mammalia) in the Early Eocene of Europe

The first representative of the extinct mammalian order Taeniodonta in Europe is described, Eurodon silveirinhensis n. gen., n. sp., from the early Eocene locality of Silveirinha, Portugal. A formerly enigmatic form, Lessnessina Hooker, 1979, from Abbey Wood, England, and approximately contemporary, is also referred to the Taeniodonta.

Upper Paleocene-Early Eocene mollusks of Silveirinha (Figueira da Foz, West Central Portugal)

A collection of fossil gastropods and bivalves assembled at the Thanetian/Ypresian vertebrate site of Silveirinha (Figueira da Foz, West Central Portugal) is analysed from the point of view of systematics and palaeoecology. The diversity is scarce but the age and exceptional characteristics of the site are factors that substantiate a detailed study. The taxa identified are: Bithynia soaresi sp. nov., Gyraulus antunesi sp. nov., Chlamys sp. and Cardiiacea gen. sp. indet. The prevailing of freshwater gastropods and the occurrence of 2 fragments of marine bivalves suggest a palaeoenvironmental setting that is in conformity with interpretations already established, which are based both in sedimentologic and vertebrate data. These interpretations point out the existence of a freshwater environment opened from time to time to marine influences, resulting from a palaeoatlantic coast placed some kilometres westwards.

Neochelys sp. (Chelonii, Erymnochelyinae), from Silveirinha, early Eocene, Portugal

Constituted of isolated fragments with a smooth decoration, the turtle material from Silveirinha is examined in order to define its sure belonging to Neochelys, by comparison with other smooth turtles which may be present during the Palaeogene of Europe (freshwater Testudinidae, Erymnochelyinae, Bothremydidae). The elements are compared with the already known Neochelys species of the Eocene European localities. Questions are made about the possible geographical migrations of turtles between South and North during the early Eocene of western Europe. The phyletic relationships cannot be established but the species, seeming new and one of the more primitive as a whole (after the preserved elements), is the older from the Iberian Peninsula.

Assessing Reading Abilities of Mechanical Engineering College Students: A Prospecting Study*

Reading is a basic competence that students have to master to be successful. Despite this fact, recent studies show that there may be a significant decline in the reading abilities of college students, one of the most educated segments of any population. This work is a prospecting study regarding the assessment of reading abilities of college students, namely in the context of Engineering education. Based on an existing screening test for assessing reading difficulties of children and teenagers, this work presents the results obtained by administrating that test to students at a top engineering institution in Portugal. An outcome of this study is the determination of a time range suitable for a massive, time limited, use of the previously mentioned test to assess college students, thus enabling a basic tool that will permit, in future works, to screen reading abilities in wider college populations. This work also shows evidence that ca. 20% of college students present a poor reading performance, revealing a strong need for monitoring college students’ reading abilities along different generations.

Phonological development in relation to native language and literacy: Variations on a theme in six alphabetic orthographies

Phonological development was assessed in six alphabetic orthographies (English, French, Greek, Icelandic, Portuguese and Spanish) at the beginning and end of the first year of reading instruction. The aim was to explore contrasting theoretical views regarding: the question of the availability of phonology at the outset of learning to read (Study 1); the influence of orthographic depth on the pace of phonological development during the transition to literacy (Study 2); and the impact of literacy instruction (Study 3). Results from 242 children did not reveal a consistent sequence of development as performance varied according to task demands and language. Phonics instruction appeared more influential than orthographic depth in the emergence of an early meta-phonological capacity to manipulate phonemes, and preliminary indications were that cross-linguistic variation was associated with speech rhythm more than factors such as syllable complexity. The implications of the outcome for current models of phonological development are discussed.
