O sujeito em situação-limite: o cogito torquatiano

Ao estabelecer um diálogo com o cogito de Descartes, o cogito torquatiano aponta para um sujeito em crise, fragmentado, contraditório, aberto e plural, desconstruindo a idéia humanista e cartesiana de sujeito como ser autônomo, dotado de uma personalidade coerente. O comportamento de Torquato Neto é muito bem representado pelo mito vampírico e pela metáfora do escorpião, definitivamente amalgamados à persona e à imagem do poeta.Palavras-chave: Torquato Neto; anos 60; arte/comportamento; literatura brasileira; poesia contemporânea; crise do sujeito.

O sujeito interpretador da realidade: uma leitura de La clairvoyance (Autoportrait), de René Magritte

Partindo do conceito de surrealismo e das particularidades de Magritte, chega-se à La clairvoyance, quadro em que esse pintor mostra como a realidade é interpretada pelo sujeito, o qual acaba por transformá-la.Palavras-chave: Sujeito; surrealismo; filosofia aristotélica; semiótica peirceana; cultura; arte.

Romance e filosofia

Análise dos modos de relacionamento históricos entre o romance e a filosofia e das conseqüências positivas e negativas desse fato. O ensaio sustenta que hoje, à época da indústria cultural e, portanto, do predomínio da literatura de entretenimento, essa relação tem se tomado prejudicial tanto para a filosofia como para o romance, favorecendo o aparecimento de romances destinados a nos fornecer a ascese mística ou intelectual. Nesse período, a relação positiva entre essas duas atividades migrou para a crítica literária de extração filosófica, a única capaz hoje de questionar a natureza social do romance.Palavras-chave: Romance e filosofia; crítica literária; romance e indústria cultural; crítica filosófico-literária.

Em busca do sentido: uma análise das estratégias de processamento textual em O milagre das folhas, de Clarice Lispector

This text aims to elucidate the textual processing strategies that give meaning to chronicle "The miracle of the leaves", of Clarice Lispector (1920-1977). Therefore, it starts from the basic postulate that the meaning is not in the fabric or verbal imagery, but the meanings constructed from the elements of language that are there to meet with the reader (BRONCKART, 2009, p. 257). Justified this reading strategy, since the chronic Lispector reveals multiple meanings endowed with a language and dialogue. The text processing is discussed in terms of an audience potentially youthful element that assigns characteristics relevant to the understanding of the functioning of this type of text in relation to younger readers. To achieve the goal, we start from the assumption that chronic, being a literary text endowed with aesthetic validity, not only conveys a content, but recreates it, adding to it new meanings.

Caldecott, Kipling, Rossetti: textos infantis vitorianos

Through brief comments on famous texts of Randolph Caldecott, Rudyard Kipling and Christina Rossetti, we intend to show to the reader aspects of children’s literature written in the reign of Queen Victoria (1837-1901), in which authors inherited the Romantic idea that child and childhood are pure, close to nature in a way that the adult man is not. Moralizing texts, they taught children how to be an adult.

Risk factors for birth-related perineal trauma: a cross-sectional study in a birth centre

Aim and objectives. To identify maternal, newborn and obstetric factors associated with birth-related perineal trauma in one independent birth centre. Background. Risk factors for birth-related perineal trauma include episiotomy, maternal age, ethnicity, parity and interventions during labour including use of oxytocin, maternal position at time of birth and infant birth weight. Understanding more about these factors could support the management of vaginal birth to prevent spontaneous perineal trauma, in line with initiatives to reduce routine use of episiotomy. Design. Cross-sectional study. Methods. Data were retrospectively collected from one independent birth centre in Brazil, during 20062009. The dependent variable (perineal trauma) was classified as: (1) intact perineum or first-degree laceration, (2) second-degree laceration and (3) episiotomy (right mediolateral or median). Results. There were 1079 births during the study period. Parity, use of oxytocin during labour, position at time of giving birth and infant birth weight were associated with second-degree lacerations and episiotomies. After adjusting for parity, oxytocin, maternal position at the expulsive stage of labour and infant birth weight influenced perineal outcomes among primiparae only. Conclusions. Although the overall rate of episiotomies in this study was low compared with national data, it was observed that younger women were most vulnerable to this intervention. In this age group in particular, the use of oxytocin as well as semi-upright positions at the time of birth was associated with second-degree lacerations and episiotomies. Relevance to clinical practice. The use of upright alternative positions for birth and avoidance of use of oxytocin could reduce the risk of perineal trauma from lacerations and need to perform episiotomy.

A comparison of time-motion performance between age groups in judo matches

The aim of this study was to compare time-motion indicators during judo matches performed by athletes from different age groups. The following age groups were analysed: Pre-Juvenile (13-14 years, n=522), Juvenile (15-16 years, n 353); Junior (19 years, n = 349) and Senior (>20 years, n = 587). The time-motion indicators included: Total Combat Time, Standing Combat Time, Displacement Without Contact, Gripping Time, Groundwork Combat Time and Pause Time. Analysis of variance (ANOVA) one-way and the Tukey test, as well as the Kruskal-Wallis test and Mann-Whitney (for non-parametric data), were conducted, using P < 0.05 as significance level. The results showed that all analysed groups obtained a median of 7 (first quantile - 3, third quantile - 12) sequences of combat/pause cycles. In total time of combat, the result was: for Total Combat Time, Standing Combat Time and Gripping Time: Pre-Juvenile and Senior were significantly longer than Juvenile and Junior. Considering Displacement Without Contact, Junior was significantly longer than all other age groups. For Groundwork Combat Time, Senior was significantly longer than all other age groups and Pre-Juvenile was longer than Junior. These results can be used to improve the physiological performance in intermittent practices, as well as technicaltactical training during judo sessions.

Natural history of an ant-plant-butterfly interaction in a Neotropical savanna

Non-myrmecophilous lepidopteran larvae using plants bearing ant attractants such as extrafloral nectaries are good models for studying morphological and behavioural mechanisms against ant predation. Udranomia spitzi (Hesperiidae) is a butterfly whose larvae feed on leaves of Ouratea spectabilis (Ochnaceae), a plant with extrafloral nectaries. We described the early stages of U. spitzi, and used field observations and experiments to investigate the defensive strategies of caterpillars against predatory ants. Larvae pass through five instars and pupation occurs inside larval leaf shelters. Ant-exclusion experiments revealed that the presence of ants did not affect significantly caterpillar survival. Predation experiments showed that vulnerability to ant predation decreased with increase in larval size. The present study showed that predatory ants are not as relevant as demonstrated for other systems, and also illustrates how observational data and field experiments can contribute to a better understanding of the biology and ecology of a species of interest.

New cytogenetic aberrations found in a case of aggressive retinoblastoma

We describe a case of retinoblastoma with an atypical presentation and previously unreported cytogenetic aberrations. A 19-month-old girl with left intraocular retinoblastoma was treated with enucleation and chemotherapy. The disease showed aggressive evolution within a short period between diagnosis and relapse. Eight months after diagnosis, a new large tumor was present in the orbit of the right eye, with diffuse bone pain, pancytopenia and diffuse infiltration into the bone marrow and the central nervous system. The child did not respond to treatment and died. Cytogenetic studies made with G-banding, FISH and SKY analysis showed chromosomal aberrations commonly associated with retinoblastoma, including del(13q), i(6+1, and monosomy 16, along with others that had not been reported previously, including dup(5q), dic(15;22) and add(14q). The new chromosomal aberrations may be related to the aggressiveness of the disease in this case.
