Círculos ao invés de linhas: em busca de valores e princípios estruturantes da gestão social. Projeto juventude, participação e autonomia (Instituto Universidade Popular - UNIPOP)

The organizations are characterized as dynamic spaces, they are being revisited and redefined, because they constitute structural human spaces and new vain outlines won expression. As it begins, of the non consensus in its conception, it is explicit the complexity degree that is identified in the plurality and diversity, brought by the people that compose them, characterizing it as accomplishment space, of happiness and also of conflict, of relationships of power and organizational limits and from birth and burial of faiths, values, norms, symbols, knowledge and rituals, therefore, deeply human. In that way, to know the administration of the organization is preponderant condition for the format of the human relationships to be delineated in its living. Like this the work makes an option in knowing the social administration, this work tries to know and analyze the values and beginnings of the social administration; revealling characteristics and specificities of the organizational performance of UNIPOP that contribute to the formation of the conception of Social Administration, it tends as source of the information the managers of the institution; to identify the formative values of UNIPOP that contribute to the youths' partner-political action in the community, tends for reference the current students of the organization and last to evaluate values structurates and supporting that interconnection between the organizational Administration, formation youth's program, participation and autonomy and attendance, starting from the existences gained by the exits, of that program. This way, the research will be qualitative, looking for understanding starting from their documents, the existence of those values

Os programas de incentivo à cultura e o processo de fomento às organizações culturais no rio grande do norte: o caso da Casa da Ribeira em Natal

Since the emergence of the first demands for actions that were intended to give greater attention to culture in Brazil, came the first discussions which concerned the way the Brazilian government could have a positive influence in encouraging the culture, as is its interaction with the actors interested and involved with the cause. During the military dictatorship, there were programs which relied on the direct participation of the State to ensure that right, from the viewpoint of its support and implementation of public resources in developing the "cultural product" to be brought to society in its various forms of expression - all this, funded by the government. It is an example of "EMBRAFILMES" and "Projeto Seis e Meia", continued until the present day in some regions of the country, though maintained by entities not directly connected with the administration or the government. However, it was from the period of democratization and the end of the dictatorship that the Brazilian government began to look at the different culture, under its guarantee to the society. Came the first incentive laws, led by "Lei Sarney" Nº 7.505/86, which was culture as a segment which could receive foreign assistance in order to assist the government in fulfilling its public duty. After Collor era and the end of the embargo through the encouragement of culture incentive laws, consolidated the incentive model proposed in advance of Culture "Lei Sarney" and the federal laws, state and local regimentares as close to this action. This applies to the Rouanet Law (Lei Rouanet), Câmara Cascudo Law (Lei Câmara Cascudo) and Djalma Maranhão Cultural Incentive Law (Lei de Incentivo à Cultura Djalma Maranhão), existing in Natal and Rio Grande do Norte. Since then, business entities could help groups and cultural organizations to keep their work from the political sponsorship under control and regiment through the Brazilian state in the form of their Cultural Incentive Law. This framework has contributed to the strengthening of NGOs and with the consolidation of these institutions as the linchpin of Republican guaranteeing the right to access to culture, but corporate social responsibility was the one who took off in the segment treated here, through the actions of Responsibility Cultural enterprises arising from the Cultural Organizations. Therefore, in the face of this discourse, this study ascertains the process of encouraging the Culture in Rio Grande do Norte from the Deviant Case Analysis at the Casa da Ribeira, the main Cultural Organization that operates, focused action in Natal in order to assess the relationships established between the same entity and the institutions which are entitled to maintain the process of encouraging treated in this study - Enterprise, from the viewpoint of corporate sponsorship and Cultural Responsibility and State in the form of the Laws Incentive Funds and Public Culture Incentive

Eficiência e razão de hedge: uma análise dos mercados futuro brasileiros de boi, café, etanol, milho e soja

This research aims to investigate the Hedge Efficiency and Optimal Hedge Ratio for the future market of cattle, coffee, ethanol, corn and soybean. This paper uses the Optimal Hedge Ratio and Hedge Effectiveness through multivariate GARCH models with error correction, attempting to the possible phenomenon of Optimal Hedge Ratio differential during the crop and intercrop period. The Optimal Hedge Ratio must be bigger in the intercrop period due to the uncertainty related to a possible supply shock (LAZZARINI, 2010). Among the future contracts studied in this research, the coffee, ethanol and soybean contracts were not object of this phenomenon investigation, yet. Furthermore, the corn and ethanol contracts were not object of researches which deal with Dynamic Hedging Strategy. This paper distinguishes itself for including the GARCH model with error correction, which it was never considered when the possible Optimal Hedge Ratio differential during the crop and intercrop period were investigated. The commodities quotation were used as future price in the market future of BM&FBOVESPA and as spot market, the CEPEA index, in the period from May 2010 to June 2013 to cattle, coffee, ethanol and corn, and to August 2012 to soybean, with daily frequency. Similar results were achieved for all the commodities. There is a long term relationship among the spot market and future market, bicausality and the spot market and future market of cattle, coffee, ethanol and corn, and unicausality of the future price of soybean on spot price. The Optimal Hedge Ratio was estimated from three different strategies: linear regression by MQO, BEKK-GARCH diagonal model, and BEKK-GARCH diagonal with intercrop dummy. The MQO regression model, pointed out the Hedge inefficiency, taking into consideration that the Optimal Hedge presented was too low. The second model represents the strategy of dynamic hedge, which collected time variations in the Optimal Hedge. The last Hedge strategy did not detect Optimal Hedge Ratio differential between the crop and intercrop period, therefore, unlikely what they expected, the investor do not need increase his/her investment in the future market during the intercrop

Utilização da Berberina na Identificação dos Mastócitos do Molusco Anomalocardia brasiliana

Berberine is an alkaloid used as a fluorochrome in the identification of heparin and DNA. Enerback, 1974, described the technique used until today to study granules rich in heparin of vertebrate mast cells. Santos et al., 2003, studied mast cells of the mollusk Anomalocardia brasiliana using biochemical and histological analysis. This work used the fluorescent dye berberine technique to improve characterization of these cells. Mollusk organs (ctenidium and mantle) were processed with routine histological techniques. Tissue sections were treated with berberine 0,02% in redistilled water acidified to pH 4, by the addition of citric acid for 20 minutes. The visualization was made through fluorescence microscopy with ultraviolet region emission. The mast cell fluorescence had a strong yellow color, where cell nuclei appeared more greenish. This result was very similar to the ones reported before. Mast cells are location at the epithelium surface is the same in both organs, mantle and ctenidium. The fluorescence was easily observed in the granules. Therefore, this technique showed to be good and sensitive to study mast cell of invertebrates

Estudo comparativo de carragenanas comerciais Kappa, Iota e Lambda no processo inflamatório em ratos :edema intraplantar e pleurisia

The Iota, Kappa and Lambda commercial carrageenans are rarely pure and normally contain varying amounts of the other types of carrageenans. The exact amount of impurity depends on the seaweed source and extraction procedure. Then, different analysis methods have been applied for determination of the main constituents of carrageenans because these three carrageenans are extensively used in food, cosmetic and pharmaceutical industry. The electrophoresis of these compounds proved that the carrageenans are constituted by sulfated polysaccharides. These compounds were characterized by colorimetric methods and was observed that the Lambda carrageenan shown the greater value (33.38%) of sulfate. These polymers were examined by means of 13C NMR spectroscopy and infrared spectra. The polysaccharides consisted mainly of units alternating of sulfated galactoses and anhydrogalactoses. The aim of the study was also to test the inflammatory action of these different polysaccharides. A suitable model of inflammation is acute sterile inflammation of the rat hind limb induced by carrageenan. Paw edema was induced by injecting carrageenans (κ, ι and λ) in saline into the hind paw of a male Wistar rats (175–200 g). The pathway to acute inflammation by carrageenan (kappa, iota and lambda) were expressed as time-edema dependence and measured by paw edema volume. For this purpose, was used an apparatus (pakymeter), which makes it possible to measure the inflammation (swelling of the rat foot) with sufficient accuracy. The results showed that κ-carrageenan (1%) have an edema of 3.7 mm and the paw edema increase was time and dose dependent; the ι-carrageenan (0.2%) caused an edema of 4 mm and the λ-carrageenan (1%) caused an edema of 3.6 mm. Other model was used in this study based in the inflammation of pleura for comparatives studies. Injection of carrageenans into the pleural cavity of rat induced an acute inflammatory response characterized by fluid accumulation in the pleural cavity, a large number of neutrophils and raised NO production. The levels of NO were measured by Griess reactive. The ι-carrageenan caused the greater inflammation, because it has high concentration of nitrite/nitrate (63.478 nmoles/rat), exudato volume (1.52 ml) and PMNs (4902 x 103 cells). Quantitative evaluation of inflammations of rats is a useful and important parameter for the evaluation of the efficacy of anti-inflammatory drugs
