Consciência e crítica da linguagem: Graciliano Ramos / Language awareness and criticism: Graciliano Ramos

Uma leitura atenta da ficção de Graciliano Ramos pode revelar uma forma aguda de refletir o mundo através de uma reflexão anterior sobre a própria linguagem da literatura e da sociedade. É uma leitura desse teor que se pretende mostrar, apoiada na conhecida teoria das funções da linguagem de Jakobson. Num jogo constante entre as funções fática e metalingüística, Graciliano Ramos demonstra visível consciência dos problemas de linguagem, cujo tratamento moderno aponta uma postura bastante crítica (via linguagem) perante o homem e a vida. An attentive of Graciliano Ramos’ fiction reveals a deep form of reflection on the world thorough a previous reflection on the very language of literature and society. Such a reading is here attempted based on Jakobson’s well known theory of language functions. In a constante play between the fatic and the metalinguistic function, Graciliano Ramos demonstrates a clear awareness of the problems of language, whose modern treatment points at a very critical poise (via language) before man and life.

Histological analysis of the periodontal ligament and alveolar bone during dental movement in diabetic rats subjected to low-level laser therapy

Objective: The purpose of this research was to evaluate the histological changes of the periodontal ligament and alveolar bone during dental movement in diabetic rats subjected to low level laser therapy (LLLT).Methods: The movement of the upper molar was performed in 60 male Wistar rats divided into four groups (n = 15): CTR (control), DBT (diabetic), CTR/LT (irradiated control) and DBT/LT (irradiated diabetic). Diabetes was induced with alloxan (150 mg/kg, i.p.). LLLT was applied with GaAlAs laser at 780 nm (35 J/cm(2)). After 7, 13 and 19 days, the periodontal ligament and alveolar bone were histologically analyzed.Results: The mean of osteoblasts (p < 0.01) and blood vessels (p < 0.05) were significantly decreased in DBT compared with CTR at 7 days, whereas the mean of osteoclasts was lower at 7 (p < 0.001) and 13 days (p < 0.05). In DBT/LT, only the mean of osteoclasts was lower than in CTR (p < 0.05) at 7 days, but no difference was observed at 13 and 19 days (p > 0.05). The collagenization of the periodontal ligament was impaired in DBT, whereas DBT/LLT showed density/disposition of the collagen fibers similar to those observed in CTR.Conclusions: LLLT improved the periodontal ligament and alveolar bone remodeling activity in diabetic rats during dental movement.

Integrated analysis environment for the Movement Assessment Battery for Children

Developmental Coordination Disorder (DCD), a chronic and usually permanent condition found in children, is characterized by motor impairment that interferes with a child's activities of daily living and with academic achievement. One of the most popular tests for the quantitative diagnosis of DCD is the Movement Assessment Battery for Children (MABC). Based on the Battery's standardized scores, it is possible to identify children with typical development, children at risk of developing DCD, and children with DCD. This article describes a computational system we developed to assist with the analysis of results obtained in the MABC test. The tool was developed for the web environment and its database provides integration of MABC data. Thus, researchers around the world can share data and develop collaborative work in the DCD field. In order to help analysis processes, our system provides services for filtering data to show more specific sets of information and present the results in textual, table, and graphic formats, allowing easier and more comprehensive evaluation of the results.

The modern math movement(s): an essay on how elementary school teachers in Brazil gave meaning to it

The main goal of this paper is to discuss the production of meaning of the Modern Math Movement. The main sources were data available in school archives and interviews with former teachers that we use in order to focus on the diversity of perspectives -that complement it or oppose it-, which comes up when teachers refer to the Movement. Using this process of signification, teachers whether accept it, invalidate it or adapt it to guidelines imposed to them in their teaching activities. We establish a methodology by following the premises of Oral History to gather oral testimonies. The theoretical foundations in which this article is written are the guidelines of Paul Ricoeur's Hermeneutics, John Thompson's Depth Hermeneutics and Bolivar's narrative analysis.

Investigation of the effect of movement and irrigation systems on temperature in the conventional drilling of cortical bone

We have compared the results of the external irrigation technique with those of a double irrigation technique with continuous intermittent movement. Maximum thermal measurements were made in the cortical part of 10 samples of bovine ribs during osteotomy to simulate the preparation of a surgical bed for the installation of dental implants at a depth of 10 mm Twenty specimens were drilled for each group: external irrigation and continuous movement (control group 1, CG1); external irrigation and intermittent movement (control group 2, CG2); double irrigation and continuous movement (test group 1, TG1); and double irrigation and intermittent movement (test group 2, TG2). The double irrigation technique gave significantly better results regardless of the drilling movement used. Thermal increases between samples was 19.2% in group CG1, 10.4% in CG2, 5.4% in TG1, and 3.4% in TG2. The double irrigation technique produced a significantly smaller increase in temperature in the cortical bone during both types of drilling (p = 0.001), which illustrated its greater efficiency compared with that of the external irrigation technique.

Reproductive migration of fish and movement in a series of reservoirs in the Upper Parana River basin, Brazil

AbstractThis study evaluates the effectiveness of two fish passes at two hydropower dams (Canoas I and II) in the Upper Parana basin, which form part of a cascade of three reservoirs. Fish from 12 migratory species (3089 specimens) were captured during their ascending, reproductive migration and were tagged with hydrostatic tags. The recapture data (294 specimens over two consecutive years) showed that there is a strong tendency for the maintenance of ascending migration through reservoirs with fish passes but with differences in migratory activity within the same species. No eggs, larvae or juveniles of these species were found in samples collected over 5 years in the reservoirs above the fish passes. These data suggest that fish passes have contributed to the restoration of the migratory routes of adult fish but that in the absence of suitable spawning or nursery habitats for these species; they probably act as ecological traps and do not contribute to the recruitment of the species.

Explicit and implicit knowledge of environment states induce adaptation in postural control

The aim of this study was to investigate the effects of explicit and implicit knowledge about visual surrounding manipulation on postural responses. Twenty participants divided into two groups, implicit and explicit, remained in upright stance inside a moving room. In the fourth trial participants in the explicit group were informed about the movement of the room while participants in the implicit group performed the trial with the room moving at a larger amplitude and higher velocity. Results showed that postural responses to visual manipulation decreased after participants were told that the room was moving as well as after increasing amplitude and velocity of the room, indicating decreased coupling (down-weighting) of the visual influences. Moreover, this decrease was even greater for the implicit group compared to the explicit group. The results demonstrated that conscious knowledge about environmental state changes the coupling to visual information, suggesting a cognitive component related to sensory re-weighting. Re-weighting processes were also triggered without awareness of subjects and were even more pronounced compared to the first case. Adaptive re-weighting was shown when knowledge about environmental state was gathered explicitly and implicitly, but through different adaptive processes. (C) 2014 Elsevier Ireland Ltd.

The importance of sensing one's movement in the world for the sense of personal identity

Within philosophy and cognitive science, the focus in relation to the problem of personal identity has been almost exclusively on the brain. We submit that the resulting neglect of the body and of bodily movements in the world has been detrimental in understanding how organisms develop a sense of identity. We examine the importance of sensing one’s own movements for the development of a basic, nonconceptual sense of self. More specifically, we argue that the origin of the sense of self stems from the sensitivity to spontaneous movements. Based on this, the organism develops a sense of “I move” and, finally, a sense of “I can move”. Proprioception and kinesthesis are essential in this development. At the same time, we argue against the traditional dichotomy between so-called external and internal senses, agreeing with Gibson that perception of the self and of the environment invariably go together. We discuss a traditional distinction between two aspects of bodily self: the body sense and the body image. We suggest that they capture different aspects of the sense of self. We argue that especially the body sense is of great importance to our nonconceptual sense of self. Finally, we attempt to draw some consequences for research in cognitive science, specifically in the area of robotics, by examining a case of missing proprioception. We make a plea for robots to be equipped not just with external perceptual and motor abilities but also with a sense of proprioception. This, we submit, would constitute one further step towards understanding creatures acting in the world with a sense of themselves.

A dança como mediadora na formação da criança

This paper analyzes the dance, considered the oldest of the Arts, inserted in Art and Education. When you talk about dance as art, sought to articulate dance, body movement and music, because all these aspects are crucial when it comes to education in dance. Thus, this paper, by analyzing the meaning of dance over time, also made a parallel with the evolution of the concept of body that, throughout history, became the focus of sin, to currently be seen in optical freedom and autonomy, looking up from childhood, the formation of body awareness and embodiment, as a basis for identity and the formation of a positive self-image. In describing the evolution of dance, between different societies, it was shown that the tool is the dancer's own body and that for its use, it is necessary to look at its interior, human vitality, musicality and sensitivity. Proved that dance since the beginning, has been seen as a medium body, as well as desires and deepest sorrows of humanity, linked to religion, ritual or ceremonial, reaching today the freest expression of body, in modern dance. Given these considerations, based on theoretical frameworks, emphasized the importance of dance in middle school, focusing on their educational role and liberating, showing that it must be used as a tool for teaching and learning, and the development of children , given its interdisciplinary character, this Crosscutting Themes in elementary school and early childhood education curriculum benchmark. The paper concludes that, despite legislation and official documents require training for dance in the school curriculum, very little is done in this direction, which shows that there is still a choice of schools, the immobility of the pupils

Cuspal movement related to different polymerization protocols

Objective: The aim of this study to investigate the effects of different polymerization protocols on the cuspal movement in class II composite restorations. Materials and methods: Human premolar teeth were prepared with class II cavities and then restored with composite and three-step and two-step etch-and-rinse adhesive systems under different curing techniques (n = 10). It was used a lightemittingdiode curing unit and the mode of polymerization were: standard (exposure for 40 seconds at 700 mW/cm2), pulse-delay (initial exposure for 6 seconds at 350 mW/cm2 followed by a resting period of 3 minutes and a final exposure of 37 seconds at 700 mW/cm2) and soft-start curing (exposure 10 seconds at 350 mW/cm2 and 35 seconds at 700 mW/cm2). The cuspal distance (µm) was measured before and after the restorative procedure and the difference was recorded as cuspal movement. The data were submitted to two-way ANOVA and Bonferroni test (p < 0.05). Results: The type of adhesive system did not influenced the cuspal movement for all the curing methods. Standard protocol showed the highest values of cuspal movement and was statistically different from the pulse-delay and soft-start curing modes. Conclusion: Although the cuspal displacement was not completely avoided, alternative methods of photocuring should be considered to minimize the clinical consequences of composites contraction stress.

Violence against children and adolescents: awareness and attitudes of Brazilian dentists

Violence against children and adolescents, ranging from negligence to sexual abuse, is an imperative public health problem. The ill treatments are considered as nonaccidental traumas, actions or omissions against children, who suffer physical or emotional violence. The main perpetrators are fathers, mothers, guardians, family, friends or the children‘s primary caretaker. It is very important to identify abuse cases, because this allows proper medical and legal intervention. In Brazil, the law n. 8.069, of July 13, 1990, known as the ECA -Statute for Children and Adolescents (SCA), stipulates the obligation to report suspected or confirmed cases of ill treatment against a child or adolescent to the Guardianship Council of the respective locality. The health professionals play a crucial role with regard to identifying cases of violence, collecting information, making early diagnosis of suspect cases and reporting such cases to the authorities. The dentists can contribute significantly, as most injuries occur in the orofacial region. Bite marks, burns, bruising, among others, are easily identified during a dental consultation. The aim of this work was to verify the awareness and attitudes of Brazilian dentists concerning violence against children and adolescents. This research was approved by the Research Ethics Committee of the Faculty of Dentistry of Araraquara – São Paulo State University (FOAr – UNESP). Sixty-three dentists answered an open and closed questionnaire concerning their formation, knowledge, experience and attitudes towards ill-treated children and adolescents. Among other results, thirty-nine dentists (61.9%) affirmed to have the means to identify illtreatment cases, 13 (20.6%) reported having some experience on this matter, but only 8 reported the cases to the Council of Guardianship, as determined by Brazilian law. Twenty percent of the reasons presented for not notifying the Council were fear of reprisal, and 60.0% were uncertain concerning the ethical and legal implications. Physical violence was the most reported form of identified violence (76.9%), followed by negligence (38.5%). Among the 13 professionals that had experience with violence cases, in 10 cases the perpetrators were identified – in 70.0% of the cases, the parents were the originators of such violence. It was concluded that further formation and orientation are necessary, in order to prepare dentists to act correctly when, during their professional activities, they encounter cases of violence against children and adolescents.

Effect of mesenchymal stem cells on movement and urination of rats with spinal cord injury

Cell therapy has frequently been reported as a possible treatment for spinal trauma in humans and animals; however, without pharmacologically curative action on damage from the primary lesion. In this study, we evaluated the effect of administering human adipose-derived stem cells (hADSC) in rats after spinal cord injury. The hADSC were used between the third and fifth passages and a proportion of cells were transduced for screening in vivo after transplantation. Spinal cord injury was induced with a Fogarty catheter no. 3 inserted into the epidural space with a cuff located at T8 and filled with 80 mu L saline for 5 min. The control group A (n = 12) received culture medium (50 mu L) and group B (n = 12) received hADSC (1.2 x 10(6)) at 7 and 14 days post-injury, in the tail vein. Emptying of the bladder by massage was performed daily for 3 months. Evaluation of functional motor activity was performed daily until 3 months post-injury using the Basso-Beattie-Bresnahan scale. Subsequently, the animals were euthanized and histological analysis of the urinary bladder and spinal cord was performed. Bioluminescence analysis revealed hADSC at the application site and lungs. There was improvement of urinary bladder function in 83.3% animals in group B and 16.66% animals in group A. The analysis of functional motor activity and histology of the spinal cord and urinary bladder demonstrated no significant difference between groups A and B. The results indicate that transplanted hADSC improved urinary function via a telecrine mechanism, namely action at a distance.
