O estudo de populações naturais é imprescindível para compreendermos melhor a sua dinâmica, importância no ecossistema, necessidade de recursos, nível de preservação das espécies, entre outras. O cateto (Tayassu tajacu), apesar de possuir ampla distribuição geográfica e ocupar diversos tipos de habitats, pode sofrer alterações no equilíbrio de suas populações devido às grandes pressões sofridas pela caça e alterações ambientais. Vale lembrar que o sucesso reprodutivo de muitas espécies vegetais está ligado à disseminação de frutos e sementes realizada pelo cateto. Considerando a necessidade de preservação das espécies silvestres, a aplicação de metodologias moleculares é uma das formas de sabermos como se encontra a diversidade genética dessas populações e, a partir daí, criarmos medidas para trabalhos conservacionistas. Nesse sentido, o objetivo deste trabalho foi identificar o nível de polimorfismo genético-molecular entre diferentes populações de Tayassu tajacu no Brasil, demonstrando como essas populações, sujeitas a tantas interferências, encontram-se na natureza. Foram analisadas amostras de 17 indivíduos referentes a oito localidades do Brasil (Cascavel - PR, Foz do Iguaçu - PR, Cuiabá - MT, Ariquemes - RO, Rio Branco - AC, Manaus - AM, Belém - PA, e Carajás - PR). O polimorfismo foi identificado com marcadores de RAPD. Foram testados 38 primers, sendo que desses apenas nove forneceram as 30 marcas polimórficas para o estudo. Foi possível notar que a maioria dos indivíduos da mesma população ou de populações próximas não são os mais semelhantes entre si. Indivíduos de localidade distantes, como os de Foz de Iguaçu (PR) e Manaus (AM) mostraram-se mais semelhantes entre si do que com os animais das suas próprias populações. A variabilidade entre os indivíduos...(Resumo completo, clicar acesso eletrônico abaixo)

Since the 60's, the population censuses have revealed a high degree of social inequality in Brazil. The concentration of income, as measured by the Gini index, showed persistently high since then. After the year 2001, we note that the trajectory stability is disrupted and the Gini index begins to show a downward trend. In relation to poverty, there has been two periods in recent history in which there was consistent decrease in the proportion of poor in the years immediately after the Real Plan in 2003 and in the year 2003 onwards. This research aimed to analyze poverty and income distribution in rural Brazil. In this crop sector, it is noted that the average perceived by the rural population is below the Brazilian income and, therefore, there is an increase in the number of poor. In addition, income in rural areas is less concentrated compared to the urban environment. Finally, as occurred in Brazil, there is a rural improvement in indicators of poverty and inequality in the last 10 years. Finally, this paper analyzes the changes that may have contributed to the fall in inequality and rural poverty, including the policy of rural settlement, the credit program to the family farmer (PRONAF) and rural retirement

The demographic census is the largest and most important socioeconomic research of the country since it portrays the situation closer to the reality of the population. Their result allows public policy making aimed at improving the quality of life, socioeconomic development and provides information for decision making on public and private sector. Due to the large amount of data collected, the processing of such information requires increasingly use information technology to facilitate processing. Therefore, the increasingly common use of the Geographic Information System (GIS) in various fields of knowledge contributes to the job achievement given its ability to collect, store, retrieve and view data. Following this trend, the Brazilian Institute of Geography and Statics (IBGE) also used this tool in the development of cartographic inputs, wich plays a key role for the data collection range nationwide

O prestígio da ciência e da tecnologia, reforçada pela visão racionalista e cientificista – inaugurada com Revolução Científica e posteriormente corroborada no século XVII pela geração Iluminista de filósofos e cientistas – é hoje um dos fatores determinantes do desenvolvimento econômico de uma nação. Estando os resultados desse progresso científico-tecnológico presentes atualmente no cotidiano mais íntimo da população, são também determinantes do perfil social e cultural da mesma. A mídia, responsável pela disseminação de informações em geral, deve atuar diretamente na proliferação da informação científica para a população não acadêmica não apenas informando, mas incitando à critica e colaborando para a crescente democratização da atividade científica. O presente trabalho tem por objetivo traçar o perfil histórico da presença da Ciência na Mídia impressa brasileira, através de uma revisão bibliográfica sobre o assunto. Para isso, fez-se um apanhado geral do estabelecimento das atividades jornalística e científica no país – inicialmente separadas e posteriormente atreladas – contextualizando-as no panorama mundial e comparando especificamente a atividade do Jornalismo Científico com outras iniciativas internacionais semelhantes

O objetivo maior deste trabalho é contribuir para se diagnosticar qual a conjuntura atual do setor microfinanceiro no Brasil. Para tanto, inicia uma exposição histórica, com o intuito de demonstrar quais as variáveis condicionantes de nosso estágio atual, chegando até ao último programa lançado pelo governo federal com a finalidade de fomentar os serviços financeiros entre a população de baixa renda - vale ressaltar, o Programa Nacional de Microcrédito Produtivo Orientado (PNMPO). A partir dessa fase, inicia uma exposição dos novos obstáculos, criados, paradoxalmente, no seio do PNMPO e ligados ao excesso de regulação, a serem transpostos para se desenvolver a indústria de microfinanças no país, propondo soluções para estes. Por fim, faz um estudo de caso de uma inovação social, ligada à economia solidária, que apresenta ótimos resultados no que tange a democratização dos serviços microfinanceiros, ocorrida em Fortaleza/CE: o Banco Palmas

Recently, some countries outside the Triad (Japan, Europe and the United States) have assumed an important role in the pharmaceutical scenario, as large producers, among them stand out Brazil. In the 90s, there were major institutional transformations and the pharmaceutical industry has undergone a reverse specialization process, because liberalization has discouraged production of pharmaceutical chemicals and dependence of imports increased. The law of generics medicines in 1999 emerged as an attempt to increase the population's access to medicines equivalent to ones with brand, with more affordable prices. As a result of this law there was a strengthening of the national capital and a major attraction for foreign companies to brazilian market. This study aims to assess the development trajectory of the country, showing how path-dependence has culminated in greater empowerment of national pharmaceutical industries after the Generics Law in 1999

This article presents a reflection on the historical aspects and legislation on Distance Learning (DL). For this, a bibliographic and documentary research was performed with the goal of raising the necessary notes for discussion. The text begins with the characterization of the current society, the Information Society, which supports the modern distance education, which uses information and communication technologies (ICTs) to establish the process of learning teaching. Five stages of the EAD are identified. Later, the Brazilian legislation concerning the DL is punctuated, starting with the passage by Article 80 of the Guidelines and Bases Law-LBD (Law 9394/96) along with the critical analysis of Decree 5,622/05. Finally, in the final considerations is discussed the negative image that the DL carries by the Brazilian population and obstacles in the existing rules that hinder the democratization of access to education that aims DL.

The study of the size and composition of the rural household in tradicional societies in transition to modern ones is very useful as a tool in order to understand forms and organizations of the domestic groups and their possibilities of survival, social mobility e developing strategies of material accumulation. The aim of this article is to compare the size and composition of the rural households in the frontier regions of the Americas: the northwest and southwest of U.S.A with the southwest of São Paulo province in Brazil. The findings are surprising in comparative perspective, as the mean size of the American households were very high in relation to the brazilian ones. The sources used in this research are the manuscript census of the U.S.A and Brazil.

The aim of this study was to adapt the BriefCOPE Inventory for Portuguese-speaking university students. We evaluate the Portuguese BriefCOPE psychometrics qualities and estimated the BriefCOPE factorial invariance in Brazil and Portugal. The data collected from a sample of 1573 students of both nationalities did confirm the 14-factor structure of the BriefCOPE and showed both factorial, convergent and discriminant related validities. However, the factor model did not show invariance across countries indicating that the use of the Portuguese version of the BriefCOPE cannot be bailed for comparisons of scores of inter-countries' student coping.

The Family Health Strategy is a primary care public policy that is becoming a decisive step towards the transformation of the Brazilian healthcare model. This study evaluated the dental knowledge among individuals who attended a Family-Health Unit (FHU) in the city of São Carlos, SP, Brazil. Methods: The evaluation was based on a questionnaire with 20 questions about oral health, prevention and development of dental caries and periodontal disease. The questionnaire was given to 168 individuals, over 18 years of age and both sexes, to fill out under the supervision of a trained dentist. After data collection, the answers contained in the original questionnaires were entered into a database built using the program Excel® (Microsoft Corporation, USA) and a descriptive statistical analysis was done. Results: 66.67% of the subjects reported having received information about dental caries and periodontal disease before attending the FHU, and dentists were cited as the main source of such information (60.71%). With regard to dental caries, 70.24% of the individuals stated that they knew about the subject, but the majority of answers revealed incorrect explanation of it. The multifactorial etiology (bacteria/sugar/poor hygiene) was not mentioned. A low percentage of subjects (24.40%) claimed to know what periodontal disease is, and of these, the highest percentage of responses was related to gingivitis (26.83%) and gingival bleeding (12.20%). Out of all subjects, 80.36% affirmed that oral hygiene is important, and among them, the main reasons cited were the maintenance of oral health (29.63%), to avoid diseases (16.30%) and to preserve and prevent disease (14.81%). Conclusion: Responses from the questionnaires revealed deficient dental knowledge among the individuals. To improve the understanding about this issue, the information obtained through the questionnaire can be used to develop educational programs that will focus specifically on the major deficiencies found.
