Imagens mí(s)ticas do gato

La valeur évocative, magique ou my(s)thique attribuée à la relation homme/animal peut être observée dans la culture depuis les époques lointaines. Dans la symbologie animale on trouve une immense charge sémantique justifiant les croyances les plus anciennes que les êtres humains ont déjà eues. Les animaux sont à la base du symbolisme mythique et ils se constituent en tant qu une source pour la riche production artistique englobant une grande variété iconographique et des textes de nature diverse. Ayant comme référence de la symbologie animal l image my(s)thique du chat, on observe la façon par laquelle le langage poétique contemple les profils mythiquesymboliques qui ont un rapport avec ce langage, tout en mettant en relief ceux qui ont des rapports aux relations entre le monde humain et le félin. À partir de l antologie tématique Assinar a pele ; des concepts théoriques ; et des abordages mitocritiques, nous cherchons à analyser les façons par lesquelles les différentes images mythiques associées au chat ont été explorées par la poésie. La définition d une typologie englobant des catégories telles : chat domestique, chat de rue, chat femme, chat nocturne, chat démoniaque et chat divin, parmi d autres, soutient la reconnaissance d identités possibles entre ces poèmes et signale la répétition d un répertoire symbolique divers en soi, mais, cohérent avec la présence du chat dans la société humaine à travers les temps

Dinâmica de reprodução e comportamento reprodutivo de branchoneta Dendrocephalus brasiliensis Pesata, 1921 como incremento na produção de alimento vivo para peixes ornamentais

Reproductive behavior of Dendrocephalus brasiliensis Pesta, 1921(Crustacean: Anostracan). The reproductive behavior of fresh water Anostracan has been poorly investigated in carcinology specialized literature, specifically in relation to Dendrocephlaus brasiliensis Pesta, 1921, with abundant data just about the geographical distribution of that Anostracan. The objective of this work was to know the reproductive behavior of this Anostracan, in different seasons (dry and raine). For this, ripe individuals of both sexes were collected in four pond of the of Fish farming Station of Paulo Afonso (EPPA), through monthly captures in each ponds, from December 2004 to November 2005. The type of reproduction was observed after the placing in aquariums (a) of then with males and (b) other on individually, at the nauplii phase, where they stayed for 15 days until the reproductive age. The sexual proportion was calculated through the relative frequencies of males and females, every month, for the whole collection period during 10 days. the production of cysts was related to the size of the female. The male: female ratio in the study period was 1 male:1,07 female. The proportion male:female was from 48,25% : 51,75% along the year. Concerning the type of reproduction, it was observed that this specie is characteerized by sexual reproduction

O gato doméstico (Felis catus) responde à sinais gestuais? possíveis implicações do convívio social

The cats (Felis catus) were domesticated about 9,500 years ago due to the advent of agriculture, being used to control the pests that devastated the food harvested. These animals went through an artificial selection and over generations and millennia had their behavior and morphology changed by humans. This process of domestication by man gave rise to a special ability, the understanding of human pointing gestures, clearly noticed while we feed our pets. Our goal in this study was to assess the comprehension of pointing gestures by cats and also verify the influence that social interactions exerts on the development of this ability. We found that experimental subjects from both groups, solitary animals and social animals, were able to follow human indication in order to find hidden food. However, social interaction had no effect on cats performances. The ability tested here probably evolved during the process of domestication of this species, and social interaction seems to exert little or no influence upon its expression

A reprodução do espaço da pequena produção rural familiar em Canguaretama/RN

This study aimed to explore the process of reproduction of space from the small family farm production in the municipality of Canguaretama, specifically focused on foodstuffs of plant origin, seeking to understand the changes in agrarian space canguaretamense and its impact on small family farms the last 35 years. Since colonization, during the seventeenth century, the production of space agrarian Canguaretama was founded under a structure based on large ownership and cultivation of cane sugar. Secondly, it was being built a small space reserved for food production to meet both the consumption of property, but also for local marketing. In the centuries following the changes in the capitalist system imposed a new dynamic for small food production, mostly in the early twentieth century, with processing plants and mills in the area extending toward the cultivation of sugarcane. In the second half of that century, mainly in the 1980s, the cultivation of cane sugar was encouraged to produce alcohol, which led to a further expansion of sugar cane toward the areas targeted for the production of foodstuffs. Currently, the framework of small food production differs little from the period of colonization in relation to the difficulties faced by this segment of agriculture. Thus, we have a reality based on socio-spatial inequality, and the near absence of the Government, which requires urgent implementation of public policies for the production and organization of small producers into associations or cooperatives to improve the productivity and hence in their standards of living and their families

Reprodução do capital e metamorfoses espaciais : um estudo da verticalização de Ponta Negra, Natal/RN

The broach presented in this dissertation, linked to post graduate Geography´s of the Universidade Federal do Rio Grande do Norte - UFRN, more exactly about the research group entitled interdisciplinary studies unit on space and housing built . The research developed through this study has this central theme on vertical grounding of the construction in the neighborhood of ponta negra in Natal, Rio Grande do Norte. Realizing this momentum as a way of accumulation of capital in city. Rio Grande do Norte´s city. During the 2000 s , the neighborhood of Ponta Negra went through an intense process of vertical integration of its ground, Provided by many factor of conditions created from new economic, political and social functions which start to be outlined mainly from the tourism development in this neighborhood since the 80´s decade. The Tourism development and the landing planning of the ponta negra´s neighborhood promoted for the government by using order to police the city´s urbanization, beyond the sense of the civilian building actors. They enabled this neighborhood to become propitious to the real estate investments. Many ventures were built before the year of 2010 while another are on building, which, over the years, changed the sociospatyal dinamics of the neighborhood. Considering the urban space is socially built, product and condition for the reproductive process of the capitalist society, the goal of this research is to investigate the verticalization of the ground, for capital reproduction purposes. This research aims to analyze the vertical this quarter through the theory of social production of space by Henri Lefebvre. The Methodology adopted pervades for secondary and primary research, compound for bibliographic research, documentary, journal, magazines, camp research and interview, to reach the best way to analyse the dynamics of the refered neighborhood

Dinâmicas de reprodução do comércio e os novos papéis urbanos de pequenas cidades norte-rio-grandenses: um olhar a partir das redes associativistas de supermercados

The work presented here aims to make an analysis of the socio-spatial dynamics of associative supermarket chains and their importance in redefining the roles of small urban North Rio Grande cities. The theoretical approach gives priority to business as a city constituent whose understanding allows us to seize the new socio-spatial dynamics of small towns in the face of globalization and which caused changes in the scope of its commercial forms. In this sense, we understand that trade, as an essentially urban activity has a very specific characteristic, with respect to its ability to transform the content and meaning of places. Another important factor in the construction work was the context of changes in the capitalist production system with the advent of flexible production and the determinations of the economic globalization process that brought new ways of organizing trade. The empirical analysis of the research includes two associative supermarket chains, the “Rede 10” and the “Rede Seridó”, bringing together basic elements for understanding the genesis and evolution of this new organizational model of trade in small towns of the state, as well as allowed -In understand the main changes in this segment of commercial activity. The methodology we used literature in books and periodicals, collected mainly secondary data collection with the SEBRAE and the ABRAS and was still a field research where interviews were conducted forwarded along to the associative network managers to supermarkets, owners of associated facilities and with consumers of the surveyed networks .Finally, we conclude that the formation and expansion of associative supermarket chains in the context of small cities potiguares is essentially in a survival alternative traditional small traders, that sharing the associative principles albeit somewhat rigidly guided by the training cooperation networks can not only stay in the market , but to impose as a new agent in the capital of the reproduction process. Thus, the associative supermarket chains in the search for new spaces, particularly within small towns end up promoting new momentum in these cities providing different flows and interconnections with different places, giving new content and urban roles. By taking not only the condition of the place of living, but also the place to reproduce the capital, small towns offer their population better able to make purchases, thus avoiding the mandatory population shifts to other urban centers in order to meet their consumption needs.

Influência dos odores de gato e de cobra no comportamento defensivo e expressão de fos do sistema hipotalâmico de defesa de camundongo

Studies using neuronal tract-tracer in rat have shown that the anterior hypothalamic nucleus, dorsomedial division of the ventromedial nucleus of the hypothalamus and dorsal premammillary nucleus are highly connected. When the rat is exposed to predator or its odor these nuclei have shown a expression of Fos and their lesion reduces defensive behavior against predator. This set of nuclei was named the Hypothalamic Defense System. However, little is known about the response of this system to the odor of different predators or its role in mice. In this work, we exposed Swiss mice to two different predators odor (cat and snake) to verify the Fos expression in the Hypothalamic Defense System, as well as the defensive behaviors displayed. The analysis showed that the mice exposure to cat odor had an increased expression of Fos protein compared to control, while those exposed to snake odor showed no rise in Fos expression, which was corroborated by the behavioral data. Our results indicate that this distinct circuit in mice seems to act differentially to odorous stimuli of different predators, causing distinct behavioral responses of mice and that the odor of snake seems not to be perceived by Swiss mice as a threatening stimulus.

Gato-do-mato-pequeno (Leopardus tigrinus) na Caatinga: ocupação e padrão de atividade de um felídeo ameaçado e pouco conhecido na floresta tropical seca do nordeste do Brasil

While the carnivores are considered regulators and structuring of natural communities are also extremely threatened by human activities. Endangered little-spotted-cat (Leopardus tigrinus) is one of the lesser known species from the Neotropical cats. In this work we investigate the occupancy and the activity pattern of L. tigrinus in Caatinga of Rio Grande do Norte testing: 1) how environmental and anthropogenic factors influence their occupation and 2) how biotic and abiotic factors influence their activity pattern. For this we raised occurrence data of species in 10 priority areas for conservation. We built hierarchical models of occupancy based on maximum likelihood to represent biological hypotheses which were ranked using the Akaike Information Criterion (AIC). According to the results the feline occupancy is more likely away from rural settlements and in areas with a higher proportion of woody vegetation. The opportunistic killing of L. tigrinus and in retaliation for poultry predation close to residential areas can explain this result; as well as more complex vegetation structure can better serve as refuge and ensure more food. Analyzing the records of the species through circular statistics we conclude that the activity pattern is mostly nocturnal, although considerable crepuscular and a small diurnal activity. L. tigrinus activity was directly affected by the availability of small terrestrial mammals, which are essentially nocturnal. In addition, the temperatures recorded in the environment directly and indirectly affect the activity of the little-spotted-cat, as also influence the activity of their potential prey. Generally, the cats were more active when possible prey were active, and this happened at night when lower temperatures are recorded. Moreover, the different lunar phases did not affect the activity pattern. The results improve the understanding of an endangered feline inhabiting the Caatinga biome, and thus can help develop conservation and management strategies, as well as in planning future research in this semi-arid ecosystem.

Fecal androgen levels in common marmoset (Callithrix jacchus) males living in captive family groups

In captive common marmoset groups, the reproductive inhibition observed in subordinate female seems to be a result of olfactory, visual and behavioral cues from the dominant female. However, few studies have examined the relationship among adult males living in the same social group. These studies have shown that reproductive failure among peer males seems to be based on hormonal and behavioral mechanisms. New insights on sexual strategies in primates have been shown using fecal steroids, but so far no information is available for common marmoset males. In the present study, we evaluated the influence of light-dark cycle, age and reproductive condition on the profile of fecal androgens in males living in the same family group. Feces were collected from six fathers and six sons for androgen determination during the light phase of the 24-h cycle for eight days randomly distributed over a 4-week period. Androgen levels were determined by enzyme immunoassay technique. Adult sons showed higher androgen levels (166.97 ± 22.95 ng/g) than fathers (80.69 ± 44.38 ng/g) and juveniles (49.06 ± 23.15 ng/g; P < 0.05). No diurnal variation (P > 0.05) in fecal androgen profile was observed in adults or juveniles. No indication of androgen-mediated social competition between fathers and adult sons was demonstrable. These results provide basic information on fecal androgen profile useful to investigate the socioendocrinology of free-ranging common marmoset males and verify that, in contrast to daughters, the reproductive suppression of sons is not based on physiological inhibition of their gonads

Consumo, cenários comunicacionais e subjetividades juvenis

Esta comunicação articula reflexões das pesquisas "Imagens limiares e visualidades juvenis: imagética do consumo", sediada na ESPM/SP, e “Imagens de presença e de ausência: sentidos midiáticos da subjetividade juvenil”, sediada na UFRN. O consumo é referência de uma epistemologia dos processos comunicacionais/midiáticos apoiada em investigações multimetodológicas. Buscam-se critérios para pensá-lo como sistema midiático com implicações em processos materiais e produtivos, e também como regime afetual, dinâmica estésica e estética de produção de sentido vinculado a dimensões simbólicas. São investigadas práticas de consumo dirigidas ao corpo e relevantes nos processos de subjetivação de jovens urbanos tanto pela reprodução de padrões como pela criação de novas formas de apropriação de bens simbólicos

Aproximações teóricas sobre a questão ambiental internacional na sociedade global: de estocolmo 1972 ao rio de janeiro 2012

O artigo apresenta os principais elementos que compõem a questão ambiental na sociedade global, através de sua relação entre economia, meio ambiente e política internacional. A primeira parte expõe o debate ambiental no contexto internacional, enfocando-o a partir dos anos 1960, período em que os problemas ambientais surgem com mais intensidade e com eles os protestos sociais nos países centrais. Os encontros sobre política ambiental internacional foram realizados com mais frequência nos anos setenta como a conferência internacional sobre meio ambiente, a primeira chancelada pela ONU em Estocolmo, 1972. Nas décadas de 1970/1980 as autoridades governamentais reconheceram a urgência na resolução da crise ambiental e passaram a traçar estratégias para a mitigação e contenção da crise. A década de 1990 é marcada pela Conferência Rio 1992, que lançou o desenvolvimento sustentável, o qual recomenda que as gerações presentes devem se reproduzir sem comprometer a capacidade de reprodução das gerações futuras. Os encaminhamentos da terceira conferência internacional sobre meio ambiente (Johanesburgo, 2002) condicionaram a questão ambiental à necessidade da formulação de leis ambientais por parte dos Estados Nacionais e instrumentos económicos de gestão ambiental. Na Rio + 20, o tema central foi a economia verde, que surge como alternativa ao desenvolvimento sustentável e se relaciona a mitigação das mudanças climáticas, produção de baixo carbono, eficiência energética, energia renovável etc. O texto se encerra explanando sobre a questão ambiental internacional na sociedade global.

Saúde bucal no programa de saude da família: o caso do distrito sanitário norte em Natal - RN

The inclusion of the dentist in the Family Health Program (FHP) teams designates a reorganization of the mouth health care in your country and establishes a new scenario in Brazilian odontology, through of a new way to organize the basic health care, creating conditions to consolidate in mouth health practice actions, in the level of the basic attention, the validation of Unique Health System (UHS) constitutional principles. The purpose of this research is to verify if the actuation of mouth health teams (MHT) dentists, in Natal city north sanitary district, is tuned with FHP goals.The target research population was composed by all dentists working in Basic Health Units (BHU) of Natal north sanitary district. Fifth-eight questionnaires were applied and using open and closed questions we look for identify the functional characteristics of each BHU, the dentists professional attributions on each BHU, as well as the clinical procedures that they execute. This research also searched to identify the factors that facilitate and/or difficult the inclusion process and the dentists activities performance on these BHUs, as well as the necessary actions to north sanitary district MHTs to fulfill the objectives proposed by FHP. The results point that the inclusion of mouth health actions in north sanitary district FHPs brought the incorporation of new values to the used practices. Whoever, its necessary a more frequent evaluation of the carried actions, in a way they can be adapted to the real community necessities, and, is fundamental the data accompaniment, for that these serve of base for planning and redirecting activities, in a way that we do not have only a reproduction of traditional practices, fragmented and isolated, but a truly substitution of the traditional practices and a new way of promoting health
