It was used a tested instrument, self answered, with opened and closed questions about theme and sociodemographic data. The same data were stored and analyzed by Program Epi Info version 3.5.1. Results: 97,1% affirmed to know male condoms, 89,0% oral contraceptives, 87,5% female condoms, 74,3% postcoital contraceptives, 47,8% natural family planning methods, 41,9% hormonal injection, 33,1% intrauterine devices, 31,6% coitus interruptus and 1,5% other contraceptive methods.

The production of the region is processed for industries at private capital and cooperatives of producers. The study involving agricultural producers and one of the most important cooperatives of the region (C-Vale) objectified to evaluate the relationships between cooperative and producers, and the mechanisms of coordination of the productive chain. The results had disclosed that the relationships are not harmonious, generating opportunism situations, high costs of transaction and diffidence in the operations between producers and cooperative.

As technology is more and more present within the organizations, the management of knowledge has become essential to an effective management. This article deals with the inseparable relation that exists in between knowledge management, practice communities and the social networks. The analysis over this relation allows us to observe how the Information and Communication Technologies facilitated the access, the information sharing and distribution within the organizations. By this, we highlighted the applicability in the social networks of three applications of Facebook, which can be used as tools in practice communities. This way, these tools are also developed for different technological platforms, which will allow a major interaction between the organizations and their workers, partners and even their clients. Therefore the responsible usage of these technologies and of the data generated by these tools can provide a better quality on the organizational knowledge management.

Incidência de barreiras técnicas ambientais chinesas sobre a pauta exportadora brasileira: 2001-2014
Resumo:
As relações entre Brasil e China vêm se estreitando ao longo dos anos, principalmente após a entrada da China na OMC em 2001, o que os tornou grandes parceiros comerciais. Esse padrão de comércio é marcado pela exportação de produtos brasileiros abundantes em recursos naturais e importação de produtos chineses de alto uso tecnológico. Sendo assim, é notável que a grande expansão da economia Chinesa reproduz grandes impactos no meio ambiente. Entretanto, o governo Chinês mostra sinais de preocupação e está buscando formas de amenizar os problemas. Como a prioridade do governo é a prevenção de mais danos ambientais, o uso de barreiras não tarifárias de caráter ambiental é cada vez mais frequente. O presente trabalho analisa o uso dessas barreiras técnicas e seus impactos na exportação de produtos brasileiros à China. Foram calculados coeficientes que mostram, junto a outros dados empíricos, que há uma forte proteção dos produtos Reatores Nucleares (HS84), Máquinas e aparelhos elétricos (HS85) e Automóveis e tratores (HS87) quanto a essas barreiras

The theory of sexual selection states that individuals more capable of attracting, selecting and competing for partners are more successful on reproduction than the less fit individuals. Competition for sexual partners can be observed in different populations of humpback whales (Megaptera novaeangliae). These large cetaceans migrate seasonally from feeding areas, in high latitudes, to breeding areas, in low latitudes, where they spend the winter. During the breeding season females with and without calves are escorted by transient competitive groups of males. Seeking reproductive success in the same group, various males exhibit aggressive behaviors searching for proximity to the disputed female. Breeding areas are usually located in warm and shallow waters that provide greater security to newborn calves. The Abrolhos Bank, in the Bahia State, is the main breeding area of the species in Brazil. In this study, we used data collected in this region between 2003 and 2012. We tested the hypothesis that there is temporal fluctuation in the abundance of competitive groups and, thus, there is variation in the levels of competition among males during the breeding season. We expected to find higher competition at the beginning of the season since there are a large number of males competing for a small number of females available for mating, because some of them would still be pregnant with calves conceived on the previous year. As the pregnant females give birth to their calves and can again get into heat, the competition among males would be softened, represented by a smaller number of individuals in competitive groups and a larger number of groups sighted. To test this hypothesis we compared the number of individuals per group and number of groups sighted (response variables) between the beginning and the end of the reproductive season (explanatory variable) by using generalized linear models. We used the Living Planet Index (LPI),...
