El poeta José de Anchieta, a través de sus poesías, contribuyó para la formación de la literatura en suelo brasileño. Con eso, él proporcionó un encuentro entre los dos mundos lo Nuevo y lo Viejo, América y Europa representados en la unión entre los pares antagónicos que son constantes en la poética anchietana, como lo sagrado y lo profano, la muerte y la vida, lo simple y lo erudito. Su poética traduce, por lo tanto, las huellas de la antropofagia cultural, en que el indio y el blanco son uno sólo; el pagano y el cristiano, juntos, caminan para el centro de sus ideologías concebidas por la catequesis y por el popular. En esa amalgama entre las culturas, él construye un nuevo código cultural-lingüístico-literario, formando una nueva identidad para la tierra brasileña, abriendo las puertas para el barroco. Sus poemas están en cuatro lenguas: portugués, tupí, latín y español. Y de ese conjunto, nuestra disertación analiza el corpus en lengua española, que en el suelo americano deja de ser española y se vuelve ibero-americana. Como fuentes de estudio crítico-teórico, nos basamos, como ejemplos, en las obras de Haroldo de Campos, Severo Sarduy, Eugênio D Ors, Lezama Lima, Oswald de Andrade, Alfredo Bosi, Massaud Moisés. Así, esta disertación muestra, por el medio de la poesía iberoamericana de José de Anchieta el rasgo del inicio de nuestra literatura así como del barroco americano y, además, conjuga su poesía dentro del espacio de los Clásicos una vez que se comunica con estos desde el proceso de su producción. En esa intercomunicación, José de Anchieta promueve una apertura para la consciencia poética que hace parte de los grandes poetas de la Literatura Universal. Él une el Brasil, con sus matas vírgenes, con su primitivismo, al Mundo, con su censura desmedida ante la visión del Paraíso

The work, here present, has as its objective to present in a clear and distinct manner the object of study of Michel Foucault in his last years of teaching at the College de France, namely, the care of the self. We present the care of the self in its birth, in its origin, from the character Socrates and its development until the beginning of the Christian age. With a keen eye, we present Foucault with a work of return and rescue of the care of the self to the personal and academic discussions; we propose, from the self care, to the contemporary subject a problematization of their life so that from this questioning he creates for herself ways of life that are coherence, knowledge and care with which he has of must particular, his himself. Passing by the sources that served as the source of study for Foucault to sketch the birth of care of the self, we design the form with which Foucault has dealt with the documents that speak of the care of self. We present Socrates as one who by excellence ensures that the other will give birth to the forms of knowledge and care of the self or, in other words, we present the care of the self socratic-foucauldian as a constant worry of the other to pay attention to ways in which he conducts her life, it creates for themselves ways of being and, therefore, creates ethics of existence. We present, finally, the care of the self as the cause of continuous immanence of modes of subjectivation of the subject that configure themselves in a non-accepting a determined essence, but a continually updated form . The care of the self leads to a single relationship and educator of modes of subjectivation of the subject; he creates, on the dynamics of temporality, ethical ways of living, which are sustained by an internal coherence of the subject with herself; he admits no stationary nature in the training of the subject, always wants a more beautiful work of himself; he is not isolation, he needs and is made with the other. The care of the self is the principle and the telos of battles and conquests of the subject within his temporality and existence

In this work we investigate the stochastic behavior of a large class of systems with variable damping which are described by a time-dependent Lagrangian. Our stochastic approach is based on the Langevin treatment describing the motion of a classical Brownian particle of mass m. Two situations of physical interest are considered. In the first one, we discuss in detail an application of the standard Langevin treatment (white noise) for the variable damping system. In the second one, a more general viewpoint is adopted by assuming a given expression to the so-called collored noise. For both cases, the basic diffententiaql equations are analytically solved and al the quantities physically relevant are explicitly determined. The results depend on an arbitrary q parameter measuring how the behavior of the system departs from the standard brownian particle with constant viscosity. Several types of sthocastic behavior (superdiffusive and subdiffusive) are obteinded when the free pamameter varies continuosly. However, all the results of the conventional Langevin approach with constant damping are recovered in the limit q = 1

This work exams the presence of music in the imaginary constitution of spaces, taking as study s object part of the musical production of the Armorial Movement, officially casted in 1970 in the city of Recife, Pernambuco. From that so called, by the Armorial s discourse, the essence of the brazilian northeastern popular art , the armorialists has intended to make an art that express an idea of northeasternity and brazility . Tries to demonstrate how the music has exerted a basic function of condensation and spreading of the armorial aesthetics, auditorily delimiting the territory of Brazilian Northeastern and, at the same time, trying to impose a sonority to it. This work still analyses the elaboration of what would be a proper soundscape of the Northeastern and how this elaboration passes trough the desire of crystallization of an idealized space, perpetual, escape line of the characteristic modernizing and postmodernizing experience of the twentieth century, product, in turn, of the anxiety of conservation of the Northeastern as a shelter to the traditions that has been evidenced by the construction of an visibility and, also, an audibility to the so called northeastern universe. It analyses, too, the way as works the confrontation between the idea of a so called northeastern soundscape - sonorous events set taken as typical from the rural space - and a sonorous archives series produced since 1920 with the regionalist discourse, showing how was elaborated an armorial music that has intended to represent the brazilian Northeastern. It evidences how, to the elaboration of armorial music, it was managed elements from the European musical culture so called scholar. It argues that the utilization of, to the manufacture of the armorial thinking and aesthetics, of a European mimical capital, so called that way by Stephen Greenblat, was consequence of the intellectual leadership of the Movement, centered in the writer Ariano Suassuna. It argues that Suassuna, followed by the musicians and the artists of the Movement, has searched to evidence a genetic linking between what he has considered the Brazilian true popular art and the medieval Iberian culture. For in such a way, the music was taken as a formation element of the social imaginary and directed to verify a relationship between the Northeastern idealized by the Armorial and the music produced by the Movement. This work has searched, therefore, through the analysis of the armorial music, to study the possible confluences between music and the space that has produced it to, by this analysis, to think the complicity between music and history

Processing in the visual system starts in the retina. Its complex network of cells with different properties enables for parallel encoding and transmission of visual information to the lateral geniculate nucleus (LGN) and to the cortex. In the retina, it has been shown that responses are often accompanied by fast synchronous oscillations (30 - 90 Hz) in a stimulus-dependent manner. Studies in the frog, rabbit, cat and monkey, have shown strong oscillatory responses to large stimuli which probably encode global stimulus properties, such as size and continuity (Neuenschwander and Singer, 1996; Ishikane et al., 2005). Moreover, simultaneous recordings from different levels in the visual system have demonstrated that the oscillatory patterning of retinal ganglion cell responses are transmitted to the cortex via the LGN (Castelo-Branco et al., 1998). Overall these results suggest that feedforward synchronous oscillations contribute to visual encoding. In the present study on the LGN of the anesthetized cat, we further investigate the role of retinal oscillations in visual processing by applying complex stimuli, such as natural visual scenes, light spots of varying size and contrast, and flickering checkerboards. This is a necessary step for understanding encoding mechanisms in more naturalistic conditions, as currently most data on retinal oscillations have been limited to simple, flashed and stationary stimuli. Correlation analysis of spiking responses confirmed previous results showing that oscillatory responses in the retina (observed here from the LGN responses) largely depend on the size and stationarity of the stimulus. For natural scenes (gray-level and binary movies) oscillations appeared only for brief moments probably when receptive fields were dominated by large continuous, flat-contrast surfaces. Moreover, oscillatory responses to a circle stimulus could be broken with an annular mask indicating that synchronization arises from relatively local interactions among populations of activated cells in the retina. A surprising finding in this study was that retinal oscillations are highly dependent on halothane anesthesia levels. In the absence of halothane, oscillatory activity vanished independent of the characteristics of the stimuli. The same results were obtained for isoflurane, which has similar pharmacological properties. These new and unexpected findings question whether feedfoward oscillations in the early visual system are simply due to an imbalance between excitation and inhibition in the retinal networks generated by the halogenated anesthetics. Further studies in awake behaving animals are necessary to extend these conclusions

Human cooperation is fundamentally affected by reciprocal exchange, but it is also remarkably common on the context of large and symbolically marked in-groups, which promote cooperation through the feeling of belonging to a group. In this thesis, two empirical articles were produced in order to investigate how human cooperation is affected by factors such as reciprocity, in-group behavior, in-group markers and gender. We investigated this subject through the administration of online games consisting of token donations, on which the subjects faced virtual players controlled by the experiment. We found that cooperative behavior is strongly influenced by reciprocity, and it is also affected by the in-group behavior, observed on the context of the social variables place of birth, ethnicity, and religions, once all of them acted as in-group markers. The subjects´ in-group behavior was enhanced when they played with generous in-group opponents, but weakened when their in-group opponents were non-generous. It was also found that cooperation is not affected by gender, but men and women cooperated in different ways under the influence of reciprocity and in-group behavior. Women are much more reciprocal on their cooperative behavior and men are less willing to cooperate with outgroupers, even when they act generously. The overall results contribute to a better understanding of the adaptive value of cooperation, reciprocity and in-group behavior on the solution of important challenges through the human evolutionary history

The main goal in this work is to conduct a quantitative analysis of the mechanical stir casting process for obtaining particulate metal matrix composites. A combined route of stirring at semi-solid state followed by stirring at liquid state is proposed. A fractional factorial design was developed to investigate the influence and interactions of factors as: time, rotation, initial fraction and particle size, on the incorporated fraction. The best incorporations were obtained with all factors at high levels, as well as that very long stirring periods have no strong influence being particle size and rotation the most important factors on the incorporated fraction. Particle wetting occurs during stirring at semisolid state, highlighting the importance of the interactions between particles and the alloy globularized phase. The role of the alloying element Mg as a wettability-promoting agent is discussed. The shear forces resulting from the stirring system is emphasized and understood as the effect of rotation itself added to the propeller blade geometry.

The general assumption under which the (X) over bar chart is designed is that the process mean has a constant in-control value. However, there are situations in which the process mean wanders. When it wanders according to a first-order autoregressive (AR (1)) model, a complex approach involving Markov chains and integral equation methods is used to evaluate the properties of the (X) over bar chart. In this paper, we propose the use of a pure Markov chain approach to study the performance of the (X) over bar chart. The performance of the chat (X) over bar with variable parameters and the (X) over bar with double sampling are compared. (C) 2011 Elsevier B.V. All rights reserved.

In this paper, three single-control charts are proposed to monitor individual observations of a bivariate Poisson process. The specified false-alarm risk, their control limits, and ARLs were determined to compare their performances for different types and sizes of shifts. In most of the cases, the single charts presented better performance rather than two separate control charts ( one for each quality characteristic). A numerical example illustrates the proposed control charts.

The study offers a global and interpretative view of the person-environment inter-action at André de Albuquerque Plaza, in Natal, RN, according to a descriptive-exploratory approach that aimed at learning about the space converted into place, as it is perceived and experienced by users, who attribute meaning to it. The main objective was to critically analyze the relationship person-plaza, based on data collected about users perception, utilization and ascribed meaning. I have employed an Environmental Psychology multi-method approach, including informal observations, interactive poster session, videotaping and interviews. The results indicated that the plaza, besides being a passage point, is also a spot of urban convergence for several groups, particularly taxi drivers, flanelinhas, skate boarders and students. In regard to the perception of the place, an overall positive evaluation of the plaza was verified, since people perceive selectively what interests them. In terms of usage, different groups of users presented diverse patterns of utilization, also observed in the attributed meanings. The plaza is a work place for taxi drivers and flanelinhas and a sports arena for the skate boarders, with a practical meaning for both groups. For students and other users it is a place for meeting and leisure, revealing a stronger affective quality, responsible for feelings of well being, tranquility and relaxation. The data so obtained could contribute for future government projects of intervention in those spaces, aiming at its preservation as an open spot among the concrete of city buildings, offering better quality of life, not only for today, but also for future generations

Measures of mortality represent one of the most important indicators of health conditions. For comprising the larger rate of deaths, the study of mortality in the elderly population is regarded as essential to understand the health situation. In this sense, the present study aims to analyze the mortality profile of the population from 60 to 69 (young elders) and older than 80 years old (oldest old) in the Rio Grande do Norte state (Brazil) in the period 2001 to 2011, and to identify the association with contextual factors and variables about the quality of the Mortality Information System (SIM). For this purpose, Mortality Proportional (MP) was calculated for the state and Specific Mortality Rate by Age (CMId) , according to chapters of ICD- 10, to the municipalities of Rio Grande do Norte , through data from the Mortality Information System (SIM) and the Brazilian Institute of Geography and Statistics (IGBE). In order to identify groups of municipalities with similar mortality profiles, Nonhierarchical Clustering K-means method was applied and the Factor Analysis by the Principal Components Analysis was resort to reduce contextual variables. The spatial distribution of these groups and the factors were visualized using the Spatial Analysis Areas technique. During the period investigated, 21,813 younger elders deaths were recorded , with a predominance of deaths from circulatory diseases (32.75%) and neoplasms (22.9 %) . Among the oldest old, 50,637 deaths were observed, which 35.26% occurred because of cardiovascular diseases and 17.27% of ill-defined causes. Clustering Analysis produced three clusters to the two age groups and Factor Analysis reduced the contextual variables into three factors, also the sum of the factor scores was considered. Among the younger elders, the groups are called misinformation profile, development profile and development paradox, which showed a statistically significant association with education and poverty and extreme poverty factors, factorial sum and the variable related to underreporting of deaths. Misinformation profile remained in the oldest old group, accompanied by the epidemiological transition profile and the epidemiological paradox, that were statistically associated with the development and health factor, as well as with the variables that indicate the SIM quality: proportion of blank fields about the schooling and underreporting. It proposed that the mortality profiles of the younger elders and oldest old differ on the importance of the basic causes and that are influenced by different contextual aspects , observing that 60 to 69 years group is more affected by such aspects. Health inequalities can be reduced by measures aimed to improve levels of education and poverty, especially in younger elders, and by optimizing the use of health services, which is more associated to the oldest old health situation. Furthermore, it is important to improve the quality of information for the two age groups
