O léxico de uma língua sustenta-se na constante evolução de seu acervo lexical. Os responsáveis por esse dinamismo lingüístico são os neologismos, que se referem à criação de uma nova unidade léxica ou ao empréstimo de um elemento oriundo de um outro idioma. Com base em um corpus extraído de edições do caderno Informática de O Estado de S. Paulo e de entrevistas com técnicos, procuramos estudar os neologismos por empréstimo no vocabulário técnico-científico da informática, analisando a sua integração ao sistema lingüístico português, sob os pontos de vista fonético/ fonológico, morfossintático e semântico, e comentando os problemas que algumas adaptações podem acarretar à estrutura da língua e, consequentemente, à comunicação.

Este trabalho examina a atribuição de funções semânticas e funções sintáticas em relação a fatores pragmáticos num corpus do português falado, focalizando os processos marcados em que a construção de estruturas sentenciais envolva mecanismos de perspectivização. Considerando preliminarmente o postulado funcional de que a gramática depende de três módulos interdependentes - o sintático, o semântico e o pragmático - pretende-se verificar, por um lado, a relevância da estrutura temática para a determinação da estrutura sintática e, por outro, a influência dos procedimentos discursivos na organização sintático-semântico das construções sentenciais. O tratamento descritivo conduz a uma avaliação teórica do próprio modelo funcional proposto por Dik (1989) em termos da relação entre a Hierarquia de Funções Semânticas e a noção de pespectivização.

Este artigo discute as técnicas utilizadas na organização de verbetes num dicionário de usos. Procura demonstrar que a definição, a taxionomia e a descrição gramatical das palavras lexicais se fazem do ponto de vista semântico-funcional e de acordo com a estrutura argumentai das palavras na sua função predicativa.

The research presents as its central theme the study of the bibliographic record conversion process. The object of study is framed by an understanding of analogic bibliographic record conversion to the Bibliograhpic MARC21 format, based on a syntactic and semantic analysis of records described according to descriptive metadata structure standards and content standards. The objective of this research the objective is to develop a theoretical-conceptual model of syntactic and semantic of bibliographic records, from Linguistic studies of Saussure and Hjelmslev of manifestations of human language, which subsidizes the development of a computacional interpreter, focused to the conversion of bibliographic records to MARC21 Bibliographic Format, which can be confirmed both the semantic value of the informational resource represented as the reliability of the representation. Given the aforementioned objectives, the methodological trajectory of the research is based on the qualitative approach, of an exploratory, descriptive and experimental nature, and with recourse to the literature. Contributions on the theoretical plane can be envisaged regarding the development of questions inherent to the syntactic and semantic aspects of bibliographic records, and by involving, at the same time, interdisciplinarity between Information Science, Computer Science and Linguistics. Contributions to the practical field are identified by the fact the study covers the development of the Scan for MARC, a computational interpreter that can be adopted by any institution that wishes to use the conversion procedure for bibliographic record databases to the MARC21 Bibliographic Format from description and visualization schemes of bibliographic records (AACR2r and ISBD), an aspect of the research which is considered innovative.

This study aimed to characterize and compare the performance of students with Attention Deficit Hyperactivity Disorder and students with good academic performance on the readingassessment processes. Forty students ranging from 8 years and 2 months old to 10 years and 11 months old, from both genders, from 1st to 4th grades of elementary level, participated inthis study, distributed in two groups: GI, with 20 students with interdisciplinary diagnosis ofAttention Deficit Hyperactivity Disorder (ADHD), and GII, 20 students with good academic performance,paired with GI according to gender, age and school level. The students wereassessedthrough the Brazilian adaptation of the Assessment Process of Reading – PROLEC, composedof four blocks: identification of letters, lexical, syntactic and semantic processes. Statisticallysignificant difference occurred between GI and GII in the PROLEC tests, with the exception of thesame-different and lexical decision tests, indicating that the students from GI presented inferior performance when compared with students from GII. Regarding the classification of the resultsof PROLEC, there was a statistically significant difference in the lexical, syntactic and semanticprocesses and the letter and sound test, with the exception of same-different tests of identificationof letters process. The findings suggests that the group of students with ADHD showsinferior performance compared to the group without disabilities, highlighting that the attentionfactor affects the cognitive functions impairing the acquisition of skills necessary for reading.

This study aimed to characterize and to compare the performance of students with an interdisciplinary diagnosis of dyslexia and attention deficit hyperactivity disorder (ADHD) in students with good academic performance on the reading processes. Sixty students from both genders, from 2nd to 4th grades of municipal public schools in Marília - SP participated in this study, they were distributed as follows: GI, 20 students with interdisciplinary diagnosis of dyslexia; GII, 20 students with ADHD and GIII, 20 students with good academic performance, paired according to gender, age and grade level with GI and GII. The students were submitted to the application of the assessment of reading processes (PROLEC) composed by four processes: letters identification, lexical, syntactical and semantic. The results highlighted that the students of GIII showed superior performance comparing with GI and GII. There was difference between GI and GII only in low frequency word reading and non words reading of the lexical process. The inferior performance from GI and GII in the PROLEC tests can be justified by the difficulty on the coding and decoding abilities. In ADHD students this difficulty was due to impaired interaction between the visual, linguistic, attention and auditory processing and in the dyslexic students was due to failure at the phonological mediation process, which depends on the knowledge of rules of grapheme - phoneme conversion to the acquisition of word reading. These changes affect the reading achievement and the comprehension of the read text.
