Ecologia alimentar e reprodutiva da piaba-do-rabo-amarelo, Astyanax cf. lacustris (Reinhardt, 1874) (Osteichthyes: Characidae) na Lagoa do Piató, Assu, Rio Grande do Norte, Brasil

The feeding habits and biological aspects of the reproductive cycle of two-spot astyanax, Astyanax cf. lacustris (Reinhardt, 1874) were investigated. Fish samples were captured on a monthly basis, using gillnets of 4 cm mesh size, from the Piató Lake, Assu, Rio Grande do Norte, during the period of September, 2006 to August, 2007. Physico-chemical parameters, such as, temperature, electrical conductivity and dissolved oxygen of the lake were registered. The monthly values of rainfall also were obtained. The 360 individuals captured, were measured, weighed, dissected, and stomach weight and the stage of gonadal maturity were registered. The stomach contents analyses were carried out based on volumetric method, points, frequency of occurrence and applying the Index of Relative Importance. The degrees of repletion of the stomachs were determined besides the Index of Repletion relating to feeding activity variations and frequency of ingestion with limnological parameters and rainfall. The food items identified were separated into distinct groups according to their origin. Sex ratio and Gonadosomatic Relation of females were verified to determine the spawning period and fecundity. The physico-chemical parameters presented the following annual mean values: temperature = 28.8ºC, electrical conductivity = 992.5 µS.cm-1; dissolved oxygen = 4.9 mg.L-1 during the study period. The annual mean of the rainfall was 63.5 mm. The results indicate that this species present an omnivorous feeding habit with a tendency towards insectivory, with an increase in feeding activity during the dry season. The aquatic oxygen to interfere very importance in the feeding activity than the others factors physico-chemicals of water and rainfall. There was a predominance of females, with a sex proportion of 1M:7F. The macroscopic characteristics of the ovaries and testicles revealed four stages of gonadal development: immature, maturing, mature and spent. A temporal variation was observed for the gonadal development of males and females. There was reproductive activity through out the year, with peaks in the months of February, April and June to correspond with the rain of precipitation of the region. The mean fecundity was 7.681 mature oocytes, varying from 4.476 to 12.036, with mean of 7.681. There was positive relation between fecundity and body mass. Condition Factor is not an efficient indicator of the reproductive period of this species. The species A. cf. lacustris is an opportunist and is well adapted to the conditions of the semi-arid Caatinga Biome

Da crise do estado à democracia como alvo: Observações sobre o neoliberalismo a partir de Friedrich Hayek e Milton Friedman

The neoliberalism proclaims the crisis of the State in front of globalization , but, approaching two books taken as basic on this theoretical chain - The road to serfdom, of Friedrich Hayek, and Capitalism and Freedom, of Milton Friedman - to analyze this supposed dualism, the conclusion into which we arrive is another one. Remembering liberal tradition and quickly, later, analyzing critically the workmanships, can be perceived that others are the conflicts really gifts in the current capitalist reality - market versus State et capitalism versus democracy - and, from the understanding on the reading made and the theoretical trajectory of its authors, we may see as the neoliberalism locates itself in relation to these conflicts, which polar regions of these antagonisms privileges, what represents the State for itself, and what it intends as much more global philosophy than economic/politics thinking only

Lévi-Strauss Mitológicas: Mito e música entre o largo e o prestíssimo

This study was elaborated based on our research of the work Mithologiques by the anthropologist Claude Lévi-Strauss (1908-2009), which affirms that languages, indigenous myths and music are related. He proposes that the understanding of myths occurs in a similar manner as with an orchestral score. In the course of his tetralogy we investigated the musical terms used in the analysis and in the division of the chapters, especially in the first volume of his work. Several compositional procedures and forms are named. Composers in pairs are categorized: Sebastian Bach for the code, Ludwig van Beethoven for the message, and Richard Wagner for the myths. In this deduction, we structured in parts: theme and variations, sonata and fugue with the aforementioned composers. Within the greatness of anthropological study, from among over 800 myths, we selected the first five of the indigenous tribe Bororo to discuss within the Theme and Variation segment. In the Sonata part there are two myths with the same theme: The wife of the jaguar which relates to the compositional structure, and four myths about The origin of women. Finally, in the segment related to the Fugue, we collected four myths that address The shortness of life. Honoring the many terms expressed in opposition, contrast, or symmetry under consideration in Levi-Strauss work, we entitled this thesis emphasizing the migration between the tempos Largo and Prestíssimo as these are oppositional presentations in music. Fifteen musical myths accompany the work supported by selected narratives. In light of this we questioned, we questioned: how are incest, murder and other events part of a society that elevates nature as an extension of life itself? And how did Lévi-Strauss think that anthropology harmonized with music? In the preparation of this study, philosophers like Peter Sloterdijk discuss the circular territory of Mythology

Corpo e beleza: uma análise das produções da educação física, em nível de mestrado

Talking about body and beauty seems fairly familiar to physical education. We understand that the body language in the area provides many meanings over the appearance, beauty and aesthetics, thus requiring the need of criticism and the need to interrogate her to realize how physical education has been re-signified. For this purpose, considering the multiplicity of meanings that surround the body and beauty, we discussed the implications that this brings to the area of Physical Education, analyzing the conception of body and beauty in the studies in this area, at the masters level, from some questions: What conceptions of body and beauty have been discussed in the studies of physical education at the masters level? What is the relationship between the meanings of body and beauty products analyzed and identified in the models of beauty outlined in Physical Education? We understand the importance of this research and its contribution to the epistemological analysis of existing studies. And, mainly because there is a lack of studies that discuss these productions. For construction of this text and for our reflections, we rely on thoughts like David Le Breton, Claude Levi- Strauss, Michel Foucault, Maurice Merleau-Ponty, Ana Marcia Silva, Carmen Smith, Isabel Mendes, Karenin Porpino Nobrega and flounder. The present study is characterized as a qualitative research, and content analysis proposed by Laurence Bardin (1977) for data processing. The corpus was composed of eight essays in the area of Physical Education, published in the CAPES Theses Database for the period 2004 to 2008, selected from the subject and body beauty. The initial reading allowed us to select meaningful units and guide our discussions on two main themes, which make up the two chapters of the work. In the first chapter, entitled Body, beauty and culture, as evidenced understandings of body, nature and culture that are present in the work is considered. In the second chapter, Standard Body Transformations and beauty, we present the concepts of body and beauty found in the dissertation, focusing on the mutability of representations of the models of beauty in body singularities in the relations of power-knowledge and the importance given the body in society, especially with regard to physical education professionals. We have thus found that, considering the dissertations analyzed, the understanding of body and beauty has been resignified, when dealing with other aesthetic conceptions that consider the uniqueness expressed in the human body and the culture of which the individual belongs
