Pisa Syndromes in Patients with Intellectual Disability
No full textThe aim of this report is to describe Pisa syndrome in two adults with intellectual disability. This case report is significant as, to our knowledge, Pisa syndrome has not previously been reported in an individual with intellectual disability (learning disability or mental retardation). Pisa syndrome is a reversible condition characterised by sustained flexion of the head and trunk and usually caused by psychotropic medication. It may be challenging to identify this condition in individuals with intellectual disability who may have coexisting postural and mobility problems. Both patients developed sustained involuntary flexion of the trunk and head tilt (Pisa syndrome) due to psychotropic medications. Both patients were prescribed risperidone, and their condition improved as risperidone was tapered off and olanzapine was commenced. Extra vigilance is required to identify Pisa syndrome as a reversible side effect of psychotropic medication in people with intellectual disability who may have pre-existing mobility and postural abnormalities

Leituras do PISA: sentidos sobre ciências e tecnologias em sala de aula de ciências
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Físicas e Matemáticas. Programa de Pós-Graduação em Educação Científica e TecnológicaEssa dissertação trata de aspectos do funcionamento da leitura em sala de aula de ciências, a partir de três textos do campo da ciência e da tecnologia, veiculados pelo Programa Internacional de Avaliação de Estudantes (PISA) objetivando compreender que sentidos sobre Ciências e Tecnologias são produzidos pelos estudantes. Analiso as condições de produção da leitura e dos discursos envolvendo esses textos, em situações de sala de aula, na escola fundamental, na disciplina de ciências. Para tanto, realizo uma pesquisa de cunho qualitativo, adotando como suporte teórico-metodológico a Análise de Discurso (AD) de linha francesa, com destaque para as questões que envolvem a linguagem do/no ensino de ciências, em particular, o que se refere à produção de sentidos sobre ciências e tecnologias em situação de sala de aula de ciências. Nessa perspectiva discursiva a linguagem é compreendida como não transparente, pois os sentidos para um texto não são dados e nem estão à espera de serem descobertos, pois estes são construídos pelos leitores dependendo das condições de produção dessas leituras. Dessa forma, a leitura dos textos do PISA vai além da mera decodificação de palavras e imagens. Assim, foi possível perceber na leitura dos estudantes uma relação entre paráfrase e polissemia envolvendo os sentidos sobre ciências e tecnologias. Com essa pesquisa pretendo produzir uma perspectiva crítica diante dos temas dos textos e da própria avaliação do PISA; contribuir para um ensino de ciências menos neutro e passivo diante das questões científicas e tecnológicas; incluir entre as discussões para o ensino de ciências, as questões de linguagem; colocar em pauta as interpretações possíveis para os textos do PISA e a partir daí discutir as implicações dessa perspectiva de linguagem em processos avaliativos como ess
Giovanni Pagni e le iscrizioni false di Pisa (CIL XI 194*e CILXI 195*)
No full textGiovanni Pagni and the forged inscriptions of Pisa (CIL XI 194* and CIL XI 195*) (pp. 331-339)
The aim of this study is to analyze two falsae inscriptions (CIL XI 194* = Inscr.It. VII, 22 and CIL XI 195*) from Pisa. For the first time Gio-vanni Pagni (1634-1676) in Commentaria in Cenotaphia Pisana Lucii et Caii Caesarum reports these inscriptions. CIL XI 194* is a forgery modelled on the inscription from Abella (CIL X 1217). A forgery is also CIL XI 195*: it was a newly carved inscription on marble. The author tentatively links these inscriptions with the publication of Valerio Chi-mentelli, Marmor Pisanum de honore bisellii, Bononia 1666
Non-response biases in surveys of school children: the case of the English PISA samples
No full textWe analyse response patterns to an important survey of school children, exploiting rich auxiliary information on respondents’ and non-respondents’ cognitive ability that is correlated both with response and the learning achievement that the survey aims to measure. The survey is the Programme for International Student Assessment (PISA), which sets response thresholds in an attempt to control data quality. We analyse the case of England for 2000 when response rates were deemed high enough by the PISA organisers to publish the results, and 2003, when response rates were a little lower and deemed of sufficient concern for the results not to be published. We construct weights that account for the pattern of non-response using two methods, propensity scores and the GREG estimator. There is clear evidence of biases, but there is no indication that the slightly higher response rates in 2000 were associated with higher quality data. This underlines the danger of using response rate thresholds as a guide to data quality.Non-response, bias, school survey, data linkage, PISA
S band hybrid power amplifier in gan technology with input/output multi harmonic tuned terminations
No full textIn this paper, the design, fabrication, and measurements of an S band multi harmonic tuned power amplifier in GaN technology is described. The amplifier has been designed by exploiting second and third harmonic tuning conditions at both input and output ports of the active device. The amplifier has been realized in a hybrid form, and characterized in terms of small and large signal performance. An operating bandwidth of 300 MHz around 3.55 GHz, with 42.3 dBm output power, 9.3 dB power gain and 53.5% power added efficiency PAE (60% drain efficiency) at 3.7 GHz are measured
Unfinished business: PISA shows Indigenous youth are being left behind
No full textThe latest international assessment of students’ mathematical, scientific and reading literacy – the Programme for International Student Assessment (PISA) – shows that the gap between Indigenous and non-Indigenous students has remained the same for the last decade. In short, Indigenous 15-year-olds remain approximately two-and-a-half years behind their non-Indigenous peers in schooling.
This essay provides a précis of the results and analysis of some of the issues; it compares Indigenous performance in 2012 with that from previous PISA cycles; and discusses a range of implications for policy and practice
What a Difference Immigration Law Makes: PISA Results, Migration Background and Social Mobility in Europe and Traditional Countries of Immigration
No full textThe purpose of this article is to evaluate the importance of social class, migration background and command of national languages for the PISA school performance of teenagers living in European countries (France, Finland, Germany, United Kingdom, and Sweden) and traditional countries of immigration (Australia, Canada, New Zealand and the US). Econometric results show that the influence of the socioeconomic background of parents differs strongly across nations, with the highest impact found for Germany, the UK and US, whereas social mobility is more likely in Scandinavian countries and in Canada. Our empirical results imply that for students with a migration background a key for catching up is the language spoken at home. We conclude that educational policy should focus on integration of immigrant children in schools and preschools, with particular emphasis on language skills at the early stage of childhood. --PISA tests,socioeconomic status,migration,social mobility,language skills
