Abstract: phonemic awareness is the metalingüistic ability which enables the conscious approach to the phonemic level of speech and the most cognitive manipulation of these representations in this level. in this study we aim at verifying whether the phonemic stimulation in kindergarten is predictive for writing acquisition in the 1st grade. eighty-five children from public school participated in this study. we used the following procedure: 1) pre-test: intellectual evaluation, phonic and written conscious; 2) elaborating stimulus program and categorizing children in groups: experimental (ge) and a control (gc), statistically balanced; 3) program execution; 4) post-test: re-evaluating the phonic and written conscious. the results indicate that both groups evolved in all the variables from the pre-test to the post-test. qualitatively, the evolution was greater in the experimental group (ge). however, the difference between both was not significant. we suggest the following hypotheses: the number of sessions was insufficient; there were too many children per group; and/or the researchers were inexperienced in pedagogical practices.
Consciência fonológica no início da escolariza??o e o desempenho ulterior em leitura e escrita: estudo correlacional
Pestun, Magda Solange Vanzo;
Estudos de Psicologia (Natal) , 2005, DOI: 10.1590/S1413-294X2005000300009
Abstract: contemporary research has demonstrated that metalinguistic skills are fundamental for the acquisition and development of reading and writing skills. with the purpose of verifying if children who had not attended school before preschool iii, with no knowledge of reading and spelling, presented phonological awareness when entering formal schooling and if the presence of this skill favored reading and writing acquisition, 167 children from both sexes with an average age of 5 years and 8 months old, similar social-economical level, took part in this study which was carried out in three stages. in the first stage (beginning of preschool iii), the phonological awareness skill was evaluated by means of the phonological awareness test. in the second and third stages (beginning and ending of the first grade of the elementary school), the children were reassessed in their phonological awareness and evaluated in oral reading and writing with dictation of words and pseudowords. the results showed a positive correlation between phonological awareness and ulterior performance in reading as well as in writing.

Abstract: we describe the work of the interdisciplinary staff of fcm/unicamp for the diagnosis of developmental dyslexia, evaluating a 9 years old boy from the second year of a first grade public school. the procedure consisted of four stages: 1) interview with the mother (anamnesis); 2) neuropsychological evaluation; 3) specific evaluation for reading and writing skills; 4) complementary exams. the results revealed that the child presented normal intelligence, normal auditory and visual function but difficulties in reading specific test, in auditory short-term memory (specially in auditory sequences), and in phonological conscience, as well as slowness, lack of concentration, slight neurological signs and hypoperfusion of the mesial portion of the temporal lobe. these data suggest that the child has developmental dyslexia of mixed type, requiring psychopedagogic follow-up.

Abstract: Descrevemos o trabalho de uma equipe interdisciplinar da FCM/UNICAMP na avalia o de um menino de 9 anos e 3 meses aluno de escola pública de Campinas, com dislexia do desenvolvimento. O procedimento constou de 4 fases: 1) anamnese com a m e; 2) avalia o neuropsicológica; 3) avalia o específica de leitura e escrita; 4) exames complementares. Os resultados das várias avalia es revelaram que o menino apresenta inteligência normal, ausência de déficit auditivo ou visual mas dificuldades em provas específicas de leitura, em memória de curto prazo (especialmente em sequências auditivas) e em consciência fonológica, além de lentid o, falta de concentra o, sinais neurológicos menores e hipoperfus o da por o mesial do lobo temporal. Esses dados sugeriram que a crian a apresenta dislexia do desenvolvimento do tipo misto, necessitando de interven o psicopedagógica.
Revis?o por pares na Revista Brasileira de Educa??o Especial

Revista Brasileira de Educa??o Especial , 2005, DOI: 10.1590/S1413-65382005000300002
Abstract: the article discusses some issues relating to peer review in the evaluation of papers submitted to a scientific journal. such evaluation is accepted as necessary to assure the scientific quality of published articles, since the integrity of specialized literature is considered essential for science development. however, there are criticisms toward peer review, including long elapsed time between papers' submission and their publication, the time and energy spent by authors and reviewers, the subjectivity in evaluation and other problems that can introduce bias in the area. the brazilian journal of special education adopts blind review and has been quick to perform evaluation procedure. the mean time elapsed between receipt of manuscripts, passing by peer revision, consequent adjustment by authors and final acceptance, is about five and half months. in the specialized literature, there are suggestions like the elimination of evaluation and the publication of all submitted texts in electronic means, which is less expensive and more versatile than print, allowing readers to make their own evaluation. the analysis performed concludes that peer review is necessary. it points out the need to promote discussions about its own evaluation process, in order to develop more efficient procedures of quality control of articles published. it suggests that the effective evaluation is made by the scientific community, after the publication, by means of collective recognition of scientific value of the publication, through the impact it may cause on new investigations and knowledge construction in the area.
Caminhando com Dibs: uma trajetória de constru??o de conceitos em educa??o especial

Abstract: the article is an answer to the paper published by piccolo, moscardini and costa in volume 16, number 1 of this journal, in which the authors analyzed my bibliographic production published in scientific journals. some facts about my personal life, intimately related to my academic path, are described so as to enable the radical understanding of my theoretical position. a large portion of the references supporting the article was published some decades ago. this is due to the fact that great theoretical contributions in human sciences emerged in the middle of the last century. this means that the excessive concern about how up to date my references were, when evaluated in terms of chronology, leads the researchers to choose to ignore the breadth and richness of the theoretical systematization of that period.
Radiation from the extremal black holes
Luciano Vanzo
Physics , 1995, DOI: 10.1103/PhysRevD.55.2192
Abstract: The radiation from extreme Reissner-Nordstr\"{o}m black holes is computed by explicitly considering the collapse of a spherical charged shell. No neutral scalar radiation is found but there is emission of charged particles, provided the charge to mass ratio be different from one. The absence of thermal effects is in accord with the predictions of the euclidean theory but since the body emits charged particles the entropy issue is not the same as for eternal extreme black holes.
Some results on dynamical black holes
L. Vanzo
Physics , 2008,
Abstract: We give indications that outer future trapping horizons play a role in the particular semi-classical instability of an evolving black hole that produces the Hawking's radiation. These are obtained with the use of the Hamilton-Jacobi tunneling method. It automatically selects one special expression for the surface gravity of a changing horizon, the one defined a decade ago by Hayward using Kodama's theory of spherically symmetric gravitational fields. The method also applies to point masses embedded in an expanding universe and to general, spherically symmetric black holes.
Black holes with unusual topology
L. Vanzo
Physics , 1997, DOI: 10.1103/PhysRevD.56.6475
Abstract: The Einstein's equations with a negative cosmological constant admit solutions which are asymptotically anti-de Sitter space. Matter fields in anti-de Sitter space can be in stable equilibrium even if the potential energy is unbounded from below, violating the weak energy condition. Hence there is no fundamental reason that black hole's horizons should have spherical topology. In anti-de Sitter space the Einstein's equations admit black hole solutions where the horizon can be a Riemann surface with genus $g$. The case $g=0$ is the asymptotically anti-de Sitter black hole first studied by Hawking-Page, which has spherical topology. The genus one black hole has a new free parameter entering the metric, the conformal class to which the torus belongs. The genus $g>1$ black hole has no other free parameters apart from the mass and the charge. All such black holes exhibits a natural temperature which is identified as the period of the Euclidean continuation and there is a mass formula connecting the mass with the surface gravity and the horizon area of the black hole. The Euclidean action and entropy are computed and used to argue that the mass spectrum of states is positive definite.
On tunneling across horizons
Luciano Vanzo
Physics , 2011, DOI: 10.1209/0295-5075/95/20001
Abstract: The tunneling method for stationary black holes in the Hamilton-Jacobi variant is reconsidered in the light of various critiques that have been moved against. It is shown that once the tunneling trajectories have been correctly identified the method isfree from internal inconsistencies, it is manifestly covariant, it allows for the extension to spinning particles and it can even be used without solving the Hamilton-Jacobi equation. These conclusions borrow support on a simple analytic continuation of the classical action of a pointlike particle, made possible by the unique assumption that it should be analytic in complexified Schwarzschild or Kerr-Newman spacetimes. A more general version of the Parikh-Wilczek method will also be proposed along these lines.
