The relationship between rapid naming and word spelling in English

A study of the concurrent relationships between naming speed, phonological awareness and spelling ability in 146 children in Year 3 and 4 of state funded school in SE England (equivalent to US Grades 2 and 3) is reported. Seventy-two children identified as having normal phonological awareness but reduced rapid automatized naming (RAN) performance (1 standard deviation below the mean) participated in the study. A group of 74 children were further identified. These children were matched on phonological awareness, verbal and non verbal IQ, and visual acuity but all members of this group showed normal rapid automatized naming performance. Rapid automatized naming made a significant unique contribution to spelling performance. Further analyses showed that the participants with low naming performance were significantly poorer spellers overall and had a specific difficulty in spelling irregular words. The findings support the view that rapid automatized naming may be indexing processes that are implicated in the establishment of fully specified orthographic representations.

Desenvolvimento ponderal de bubalinos da raça Murrah criados em pastagem de Brachiaria brizantha no Centro-Oeste do Estado de São Paulo, Brasil

Foram analisados os dados de desempenho ponderal de bubalinos Murrah do Sistema de Produção de Leite da Universidade Estadual Paulista, Faculdade de Medicina Veterinária e Zootecnia, campus de Botucatu. Os pesos foram corrigidos às diversas idades-padrão e o modelo incluiu os efeitos de sexo (S), mês (M) e ano (A) de nascimento, classe de idade da búfala ao parto (C) e as interações S x M, S x A, S x C e M x A. As médias ajustadas e respectivos erros-padrão estimados para as características estudadas foram: Peso ao Nascer (PN): 37,71 ± 8,25kg; Peso aos 120 dias (P120): 102,08 ± 16,27kg; Peso aos 240 dias (P240): 169,84 ± 22,83kg; Peso aos 365 dias (P365): 250,59 ± 25,12kg; Peso aos 550 dias (P550): 326,13 ± 39,27kg e Peso aos 730 dias (P730): 389,80 ± 31,26kg. O efeito de sexo (S) foi significativo somente para PN e P365, sendo que machos tenderam a nascer mais pesados que fêmeas. O mês de nascimento (M) exerceu efeito sobre o PN, P120 e P730 sendo que animais nascidos em maio foram os mais pesados ao nascer, enquanto os nascidos em janeiro e maio, foram os mais pesados aos 120 e 730 dias, respectivamente. O efeito de ano de foi significativo sobre o PN, P120, P240 e P730. Os filhos de búfalas das classes de idade 1 (3 anos ou menos) e da classe 6 (10,11 e 12 anos) foram os mais leves e mais pesados ao nascer, respectivamente. O fato de a classe de idade da búfala não exercer efeito sobre os P365, P550 e P730 sugere que, em rebanhos comerciais possa ser feita a substituição de búfalas não gestantes por novilhas prenhes, apesar de esta prática reduzir a média de idade do rebanho de cria. Bubalinos da raça Murrah oriundos de rebanhos leiteiros podem ser utilizados para a produção de carne.

Prevalence of DEA 1 canine blood group system in dogs (Canis familiaris, Linnaeus, 1758) reared in Brazil

Os cães possuem cinco grupos sangüíneos bem estabelecidos, compostos por sete determinantes antigênicos eritrocitários, os quais são denominados de dog erythrocyte antigen (DEA). O grupo DEA 1 (subgrupos 1.1, 1.2 e 1.3) tem sido considerado o mais importante no que se refere às transfusões de sangue. Isto ocorre porque esse grupo possui um alto potencial para estimulação antigênica e, dessa forma, pode estimular a produção de anticorpos se um receptor DEA 1 negativo receber uma transfusão de sangue DEA 1 positivo, levando a uma reação transfusional hemolítica em uma segunda transfusão com hemácias do tipo DEA 1. A freqüência de aparecimento do grupo DEA 1 é bem conhecida em outros países, porém, até então, não havia informações disponíveis sobre o referido grupo no Brasil. No presente estudo, objetivou-se avaliar a prevalência do grupo sangüíneo DEA 1 (subgrupos 1.1 e 1.2) em cães criados no Brasil. Para tanto, 150 cães de raças, sexos e idades diferentes, triados junto ao Hospital Veterinário da FCAV/UNESP, Campus de Jaboticabal, foram submetidos a tipagem sangüínea para o grupo DEA 1 (subgrupos 1.1 e 1.2) canino, utilizando-se reagentes adquiridos comercialmente junto ao Laboratório de Imunoematologia e Sorologia da Universidade de Michigan (EUA). Os resultados obtidos neste ensaio revelaram que a prevalência geral para o grupo DEA 1 é de 91,3%, consideradas as condições e características da população estudada, compreendendo 51,3% de cães do tipo DEA 1.1, 40% de cães do tipo DEA 1.2, e os 8,7% restantes sendo negativos para o referido grupo. A partir das prevalências encontradas, calculou-se que a probabilidade de um cão DEA 1 negativo receber sangue DEA 1.1, em uma primeira transfusão feita ao acaso, é de aproximadamente 4,5%. Sendo assim, este índice reflete um risco potencial para a sensibilização de um receptor DEA 1 negativo, o que deflagraria a produção de anticorpos. Posteriormente, se este mesmo paciente recebesse uma segunda transfusão de sangue, feita ao acaso, a probabilidade de receber hemácias do tipo DEA 1.1 seria de aproximadamente 2,3%, o que representaria o risco potencial de ocorrência de uma reação transfusional hemolítica aguda. Por outro lado, a probabilidade de este cão receber sangue do tipo DEA 1.2 seria cerca de 1,8%, o que levaria a uma reação transfusional menos grave, porém potencialmente prejudicial. No presente estudo, observou-se que o risco potencial para uma reação transfusional é mínimo, quando se trata de um cão mestiço.

Conselho de Escola: cenários e desafios de uma escola pública de Natal

This dissertation work studies the Board of Director , created in 1995, in the public schools of the Rio Grande do Norte. It aims to analyze if the creation of this collegiate at Berilo Wanderley State School contributes to accomplish the participation of school segments, democratizing the decision-making in the interior of the institution. This research configures itself as a study of case with information collected together to the representatives of Board through of semi-structuralized interviews. Also they had been essential in the investigation , the informal talks and the registered direct comments in a field diary. For the data analysis we contemplate the following dimensions of the object: the institutionalization process of the Board at Berilo Wanderley State School; the insertion form of the representatives in the collegiate one; the participation of the members in the Board decisions ; the Board s role in the school management and the Board as democratization space. Based in the theoretical and empirical information that we made use, we look for to identify the limits and possibilities of the Board performance in a state public school. The research results indicate that the institutionalization of the Board of Director at the Berilo Wanderley State School presents limits to materialize an effective participation of school community in the essential decisions to the functioning of the school. Also it was possible to underline the fragility of an understanding on the part of school community, the potentialities that the Board in the process of democratization of the school has, translated in the discrepancy between the saying and making of the council members. It can be highlighted that the Board in the school only exists to correspond to a educational policy guideline, with a little significant role , without corresponding to the democratizing possibilities of the collegiate participation. In spite of all the evidenced debilities in the Board of Director experience of the Wanderley Berilo State School , it is worth clarifying that the actor participation, for more limited than either, it represents new something in the setting of the school. In this direction we detach the importance to invest in the improvement of the Board s role, because it can form itself in an educative space for the building of democratic practices in the scope of the school

A autoavaliação institucional na Escola Municipal Estudante Emmanuel Bezerra: construindo uma dinâmica de participação

This project was based on an implemented investigation of the institutional self-evaluation at Municipal Emmanuel Bezerra school, located at the west zone of Natal capital in Rio Grande do Norte state, where school individuals were analysed in interaction. A qualitative research was taken under the use of several pieces of information and collected out of several sources, such as: managing, docent and administrative staff interviews; present school legislation, political pedagogical project, scholar regiment as well as the 2013 action plans documental analyses; and the literature review focused in books and articles which treats of evaluation, State Evaluator and the public educational politics in order to promote the dialogue between school theory and reality. The institutional evaluation has been the theme debated through several studies. However, with its major focus on the evaluation systems and High Education aiming to raise competition having implying the reaching of educational quality as justification under liberal view. Notwithstanding, over the controlling function of the educational results and competition trigger amongst the educational institutions to the accruement of the received resources, it is believed that this institutional evaluation, however the system, can assist in the educational services improvement offered to the local public, when endeavoured to the purpose of supporting human development. Having the obtained data, the self-evaluation process implemented at the concerned school, the conceptions which permeate the school environment as well as the community joining given in this object lesson, was described and analysed as dialoguing with the political pedagogical project and comprehending the constitution in a democratic management

Reflexões e contribuições para o ensino de gravitação clássica no nível médio

The subject of Classic Gravitation is part of the actual curriculum for High School in Brazil, and it is taught in the first year of that education level. This master thesis presents a research regarding the subject Classic Gravitation in High School. This research was based in two complementary guidelines of research and action. The first guideline was the analysis of 21 didactic books of physics which are the more frequently used in High School, in the city of Natal/RN. The second guideline, worked after being verified the most common deficiencies presents in the didactic books, was the elaboration, followed by a practical application, of a course suggesting how to approach that subject in the classroom. The Parâmetros Curriculares Nacionais para o Ensino Médio (National Curricular Parameters for High School PCNEM) defend that Classic Gravitation is very important in the student s formation and that its study helps the comprehension of many nature s phenomena. Because of this vision of that subject by the PCNEM, the 21 analyzed books were separated in two groups: the first one, containing 10 books, was edited before the spreading of PCNEM, and the second, with 11 books, after that spreading. Whatever the group to which the didactic books belonged, the great majority of them let that subject in a second plan; two of them even suggesting, in the teacher s orientations, that the subject Gravitation can be suppressed in case of insufficient time . These analyses points that the PCNEM had produced no changes in the conception of the authors that wrote books regarding that subject. To analyze the didactic books, we elaborated a script which was used as an analysis tool, in which we put in evidence the relative importance of the historic and philosophic contextualization of the subject, the quotidian experience of the students and the interdisciplinary approach, among other aspects. It became evident that the didactic books give very little emphasis to historic aspects of the knowledge construction, to the relations with the day-by-day questions and to the interdisciplinary character of the subject Gravitation. It calls attention the non concordance among the authors opinions regarding the necessary previous knowledge or prerequisites the students should fulfill in order to begin to study Gravitation. The course we elaborated was given to a group of teachers as well as to students. In those courses we treated theoretical and practical aspects and emphasized historical questions and the ones which are related to people s daily life. The course for teachers was realized as an extra-mural activity of the UFRN and was given by the author of this thesis at the Escola Estadual Francisco Ivo Cavalcanti (a state public school in Natal/RN). There were 23 teachers present, from several public schools and several fields of knowledge. The thesis supervisor and the master degree s colleagues of the author acted as collaborators , reporting the participants opinions and speeches. The course to the students, on the other hand, had the participation of 300 regular students who belonged to 6 different 1st year classes of the High School Escola Marista de Natal (RN), in which the author acts as a physics teacher. The student s course was realized as part of the regular curriculum activities, in which three classes stood under the responsibility of the author and other three classes in charge of another Marista s teacher, who participated as a collaborator . The teacher s course as well as the students one were given in two stages, with five hours each. The first stage was divided in two moments, the first one focused on the survey of the spontaneous conceptions about gravitation, in which we worked basically with experiments of free throwing and pendulum, and the second one focused in theoretical presentations and quarrels about universe s models. In the second stage of the course we improved the study of Kepler s laws and the Newton s Universal Gravitation law, and we used as motivating tools some practices involving the construction of the solar system in scale. As instruments for evaluating both courses we used questionnaires and reported the speeches with participants opinions, beyond usual written evaluations in the course for the students. The teachers who participated in the course showed very good wills in realizing interdisciplinary practices; nevertheless, according their own speeches, they frequently came across the difficulty of how to do . From the experience we had in both courses, we conclude that the approach we propose hear to the teaching of the subject Classic Gravitation , supported on the tripod theory, practice and historical and philosophical aspects, is viable and effective. One hopes that this research may contribute in the formation of a opinion, among the teachers, concerning how to approach the subject of Classic Gravitation, and may offer suggestions in order those who want to apply that approach may develop classroom practices aiming to improve the teaching of that subject, which has a singular importance in the formation of High School students

Uma abordagem histórica para o ensino do princípio da inércia

Placed in the field of Didactic of Science, this paper proposes an approach to the introduction of the History of Science in science education, at high school level. It was designed and implemented a series of activities regarding the history of the Principle of Inertia. The aim of this approach was to give more meaning to scientific education, while opening new avenues for a better understanding of the processes of construction of scientific knowledge. The preparation of the activities involved a study of the historical development of the concept of motion, from the Aristotelian physics through physical movement concepts at medieval period, from Galileo, Gassendi, Descartes, until the first law of Newton. The strategy of teaching was applied to three classes of high school (night period) of a state public school at the city of Natal (RN). The results indicated the difficulty of overcoming alternative conceptions about movement by students. Nevertheless, we consider that the implementation of this strategy of teaching both represented gains for the learning of students, and contributed to the resizing of pedagogical practices of the teacher-researcher

Uma proposta para o ensino de eletromagnetismo no nível médio

This paper aims at building a proposal for teaching of electromagnetism in the secondary level in the state public school in Natal, RN, encompassing at the most possible comprehensive manner the fundamental aspects of electromagnetism. The methodology employed here is prioritize physical concepts rather than instruments (such as the mathematics), which should have the connotation of just tools, or of aids in the context of physics teaching in the referred teaching level. The proposal is to give teachers a consultation resource, from differentiated lesson plans, which have as main focus activities based primarily in texts and active participation of students in the teaching- learning process and the implementation of the PCN+ proposals (BRAZIL, 2000), which suggest alternative ways to make the practice in the classroom more exciting, targeting a significant teaching-learning process for both the teacher and the student. This material was applied during the 3rd and 4th term (i.e., bimester) throughout the school year of 2007, in the State School Teacher Varela Barca in two classes (3V1 and 3V2) of 3rd grade of secondary level. As evaluation of the implementation of this proposal one can cite that students were more secure when to apply the concepts, when conducting the experiments, and less anxious when formal evaluation of the evidence, showing greater motivation when presented to electromagnetism contextualized in their everyday situations. The product of this educational work includes, besides the dissertation, the lesson plans, itineraries and experimental assessment of the instruments used (Annex E to I)

Perfil de fumantes atendidos em serviço público para tratamento do tabagismo

OBJETIVO: Avaliar o perfil dos fumantes que procuraram serviço público de cessação do tabagismo. MÉTODOS: Foram avaliados retrospectivamente os dados coletados durante a avaliação para a admissão no programa de cessação do tabagismo do Ambulatório de Tabagismo da Faculdade de Medicina de Botucatu/Universidade Estadual Paulista, na cidade de Botucatu (SP) entre abril de 2003 e abril de 2007. Variáveis demográficas, uso prévio de abordagem comportamental e/ou farmacológica e/ou tratamentos alternativos para o tabagismo, grau de dependência à nicotina e comorbidades foram avaliados em 387 fumantes. RESULTADOS: em nossa casuística, 63% dos tabagistas eram do sexo feminino. A idade média dos sujeitos foi de 50 ± 25 anos. Mais da metade dos fumantes (61%) não tinha cursado o ensino médio, e 66% tinham renda mensal menor que dois salários mínimos. O grau de dependência foi elevado/muito elevado em 59%, médio em 17% e baixo/muito baixo em 24%. Embora 95% dos pacientes apresentavam comorbidades, apenas 35% foram encaminhados ao programa por um médico. Mais da metade (68%) tinha feito pelo menos uma tentativa de cessação, 83% sem um programa de tratamento estruturado. CONCLUSÕES: Os tabagistas que procuraram assistência para cessar o tabagismo apresentaram desvantagem social, dependência à nicotina alta e tentativas anteriores de cessação sem tratamento estruturado. Portanto, a intervenção para o controle do tabagismo deve contemplar as características gerais dos fumantes nos serviços públicos para que seja eficaz.
