Complex networks analysis of language complexity

Methods from statistical physics, such as those involving complex networks, have been increasingly used in the quantitative analysis of linguistic phenomena. In this paper, we represented pieces of text with different levels of simplification in co-occurrence networks and found that topological regularity correlated negatively with textual complexity. Furthermore, in less complex texts the distance between concepts, represented as nodes, tended to decrease. The complex networks metrics were treated with multivariate pattern recognition techniques, which allowed us to distinguish between original texts and their simplified versions. For each original text, two simplified versions were generated manually with increasing number of simplification operations. As expected, distinction was easier for the strongly simplified versions, where the most relevant metrics were node strength, shortest paths and diversity. Also, the discrimination of complex texts was improved with higher hierarchical network metrics, thus pointing to the usefulness of considering wider contexts around the concepts. Though the accuracy rate in the distinction was not as high as in methods using deep linguistic knowledge, the complex network approach is still useful for a rapid screening of texts whenever assessing complexity is essential to guarantee accessibility to readers with limited reading ability.

The place of (explicit) grammar within the methods and approaches of foreign language teaching: in the north, in the centre or on the margins?

This article analyzes the role that has been attributed to grammar throughout the history of foreign language teaching, with special emphasis on methods and approaches of the twentieth century. In order to support our argument, we discuss the notion of grammar by proposing a conceptual continuum that includes the main meanings of the term which are relevant to our research. We address as well the issue of "pedagogical grammar" and consider the position of grammar in the different approaches of the "era of the methods" and the current "post-method condition" in the field of language teaching and learning. The findings presented at the end of the text consist of recognizing the central role that grammar has played throughout the history of the methods and approaches, where grammar has always been present by the definition of the contents' progression. The rationale that we propose for this is the recognition of the fact that the dissociation between what is said and how it is said can not be more than theoretical and, thus, artificial.

DELAY IN THE DIAGNOSIS OF TUBERCULOSIS IN PRISONS: THE EXPERIENCE OF INCARCERATED PATIENTS

This study analyzed the causes of delay in the diagnosis of tuberculosis in the prison system, according to the experience of incarcerated patients. The theoretical and methodological framework of the French school of discourse analysis was used, which seeks to comprehend the processes of meaning production, in the relationship of language with ideology and the development of subjects in their positions. Semi-directed interviews were conducted with seven incarcerated tuberculosis patients in a hospital of Joao Pessoa, Paraiba, Brazil, between August and October 2009. The delay in the diagnosis of tuberculosis was related to the naturalization of the lack of care for the prisoner, to the interpretation of the prison as a place of death and suffering and to the deprivation of the right to health for the detainees as a result of their position in the asymmetric power relationships and ideological effects.

Impact of benign childhood epilepsy with centrotemporal spikes (BECTS) on school performance

BECTS represents the vast majority of childhood focal epilepsy. Owing to the age peculiarity of children who suffer from this disease, i.e., school-going age of between 6 and 9 years, the condition is often referred to as a school disorder by parents and teachers. Objective: The aim of this study was to evaluate the academic performance of children with BED'S, according to the clinical and electroencephalographic ILAE criteria, and compare the results of neuropsychological tests of language and attention to the frequency of epileptic discharges. Methods: The performances of 40 school children with BED'S were evaluated by applying a school performance test (SBT), neuropsychological tests (WISC and Trail-Making), and language tests (Illinois Test Psycholinguistic Abilities - ITPA - and Staggered Spondaic Word - SSW). The same tests were applied in the control group. Results: Children with BED'S, when compared to those in the control group, showed lower scores in academic performance (SPT), digits and similarities subtests of WISC, auditory processing subtest of SSW, and ITPA - representational and automatic level. The study showed that epileptic discharges did not influence the results. Conclusion: Children with BED'S scored significantly lower scores in tests on academic performance, when compared with those in the control group probably due to executive dysfunction.

A linguagem de programação aliada ao desenho na criação de jogos digitais como instrumento de arquitetura patrimonial

This research studies the use of digital games as a playful tool approach of knowledge in architecture heritage. We emphasize the potential of digital games as a tool and importance of digital drawing combined with programming language, the means by which the making of the games became possible. The models developed are based on the properties of historical and cultural interest in the city of São Carlos, Brasil.
