ABSTRACT Objective: To investigate whether Brazilian articles on cancer are published in journals with an impact factor and/or repercussion (measured by the number of citations) inferior to those that come from foreign organizations. Methods: A search was carried out in PubMed for the MeSH term “neoplasm” with the limits clinical trial, affiliation of the Brazilian author(s), and interval from July 1st, 2009 to June 30, 2010. Selected for matching were non-Brazilian related articles published from three months prior to three months after the date of publication of the Brazilian study. The numbers of citations were obtained from two databases, as well as the impact factor for the journals in which the articles were published. Results: Fortythree national and 876 related international articles were identified. The Brazilian publications had a mean impact factor of 3.000 versus 3.430 of the international ones (p=0.041). There was no statistically significant difference as to the number of citations between the two groups. The affiliation of the first author with a Brazilian or foreign organization did not significantly influence the number of citations or the impact factor. Conclusion: Brazilian articles are significantly less accepted in journals with higher impact factors, although it does not compromise its repercussion on the scientific community. PMID:23579739

South Brazilian organic propolis (OP), which has never been studied before, was assessed and its chemical composition, scavenging potential of reactive oxygen species, antimicrobial and anti-inflammatory activities are herein presented. Based on the chemical profile obtained using HPLC, OP was grouped into seven variants (OP1–OP7) and all of them exhibited high scavenging activity, mainly against superoxide and hypochlorous acid species. OP1, OP2, and OP3 had the smallest minimal inhibitory concentration (MIC) against Gram-positive bacteria Streptococcus mutans, Streptococcus oralis, and Streptococcus aureus (12.5–100 μg/mL). OP1, OP2, OP3, and OP4 were more effective against Pseudomonas aeruginosa (Gram-negative), with MIC values ranging from 100 to 200 μg/mL. OP6 showed anti-inflammatory activity by decreasing NF-kB activation and TNF-α release in RAW 264.7 macrophages, and expressing the NF-κB-luciferase reporter stable gene. Therefore, south Brazilian OP can be considered an excellent source of bioactive compounds with great potential of application in the pharmaceutical and food industry. PMID:27802316

Monteiro, Renata

2006-05-01

The objective of this paper is to present and discuss Brazilian policy concerning actions to protect breastfeeding, especially the history, international and national background, limitations, and perspectives of the Brazilian Guidelines for the Marketing of Baby Food, Pacifiers and Bottles. The Brazilian Guidelines, which play a crucial role in protecting breastfeeding against industry marketing strategies, were based on the International Code of Marketing of Breastmilk Substitutes, proposed by the World Health Organization in 1981. The first version of the Brazilian Guidelines was released in 1988, and there were subsequent revisions in 1992 and 2001/2002. In 2006, the Guidelines became national law. However, the strides made over this period in terms of regulation have been few because the law is not always observed. Thus, it is essential that all actors involved, including government officials, manufacturers and sellers of baby food and other baby products, teaching and health professionals and their associations, international bodies, and non-governmental organizations make a commitment to enforce the current law.

Full Text Available The objective of this study was to explore the evolution of internal and external commercialization of Brazilian sparkling wines during the period between 1986 and 2015, giving an overview of the current situation and its market trends, and highlighting the importance of Brazil in the world scenario for sparkling wines. This research is based on quantitative data sources provided by different institutions: International Organization of Vine and Wine (OIV, Brazilian Union of Viticulture (UVIBRA, Ministry of Agriculture, Livestock and Supply (MAPA and Brazilian Agricultural Research Corporation (EMBRAPA. Brazil is a promising country for the sparkling wine market. From 1986–2015, there was an increase of 465.6% in the sales of sparkling wine in the Brazilian domestic market, especially the last ten, which accounted for an increase of 215.7%. In 1998, Brazilian sparkling wines accounted for 70.5% of sparkling wines sold in Brazil. Today, they represent 82.1%of national market, and proved to be one of the most prestigious products from Brazilian viticulture when compared, for example, to non-sparkling wines, which 79% are imported wines. Of the imported sparkling wines consumed in Brazil, six countries account for 98.5% of the market (France: 32.7%; Italy: 24.8% and Spain: 21.9%. The volume exportation of Brazilian sparkling wine has grown significantly in recent years (4,210.2%, with Paraguay, China, Uruguay, the United States, France and the United Kingdom being the major buyers. The evolution of exports shows that Brazilian sparkling wine becomes an alternative to those produced in traditional countries, such as France, Italy and Spain, due to their quality and price. There is an increase in the commercialization of sparkling wines in the Brazilian domestic market, in addition to the growing participation of Brazil in the volume of exports in the world market, placing Brazil in a leading position in the production and sale of sparkling wines.

This main objective of this work is to present the obstacles to the Brazilian participation in the international ethanol and sugar market, specially in the European Union. Therefore it is emphasized the main reasons which conduct Brazil to discuss in the International Trade Organization the production quota system impositions and the heavy subsidy exportation used in the European Union. In despite of improving the negotiation arguments, it has been felt at the most recent International Trade Organization meeting that the Brazilian interests has got to confront international barriers to punish the Brazilian sugar with an high tax importation as in the European Union. Due to those difficulties, the possibility of opening a larger ethanol market, mainly in those countries which wish to reduce pollution emission, mixing anhydrous alcohol to gasoline appeared as a good alternative. Actually the European Community members have strategic reasons to maintain the sugar production subsidies. Brazil and most of the European Community members have been discussing an agreement to reduce the subsidies. The Brazilian victory on the appeal made in the International Trade Organization, on August the 4th; against the subsidies to the sugar conceded by EU, provoked rejection of many. (author)

PERFORMANCE INDICATORS APPLIED TO BRAZILIAN PRIVATE EDUCATIONAL INSTITUTIONS

2015-06-01

Full Text Available Initially focused on for-profit companies the Balance Scorecard (BSC has been adopted by many organizations with different objectives, such as higher education institutions (HEIs. However, it is not clear if the adoption of the BSC model is appropriate, or yet is hard to perceive how HEIs have modified and implemented this tool for evaluating educational institutions, public or privates, in Brazil. This study aims to fill the gap existent in the context of using the BSC in organizations. We intend to demonstrate how these organizations use performance indicators to measure their primary activities. A quantitative and exploratory study was developed from the analysis of performance indicators found in the web sites to Brazilian universities. A total of 91 Brazilian private universities evaluation process were reviewed. Even with a considerable amount of private HEIs there are few that have performance indicators guided by numerical and statistical data covering its main activities which is a concern for their managers in terms of managerial control.

Animal experimentation: a legal fight in Brazilian universities

2015-07-01

Full Text Available Vivisection, or the use of animals in experiments, testing or education is part of a context in which many people still think represent an emergency conflict that requires the choice of human interests rather than the interests of animals. In Brazil, the 1988 Federal Constitution, in Article 225, paragraph 1, item VII, prohibits the practice of cruelty to animals. To regulate the said device, was passed in 2008 the Law 11.794 / 2008, known as Arouca Law, establishing procedures for the scientific use of animals and the Law 9.605 / 2008, which deals with environmental crimes. However, according to Brazilian Constitution, is it possible to sustain the use of animals in teaching and research, especially in universities? The aim of this paper is to analyze the Brazilian legislation regarding the use of animals in testing, teaching and research, and to discuss the observation of this legislation during the lawsuits filled in recent years by animal advocacy organizations against several Brazilian universities. The results point to a disagreement between the practices prevailing in the universities, the legislation and the Brazilian Constitution.

Brazilian women in politics.

Sanders, T G

1987-01-01

Women are gradually gaining influence in Brazilian politics, especially since recent advances in the women's movement, but they still play a limited role. There have been journals devoted to feminism and some notable feminists since 1850. In 1932 suffragettes in Brazil gained women the right to vote. Women's associations burgeoned in the 1940s and 1950s, culminating in a peak in number of women in national elected positions in 1965. A repressive military regime reversed the process, which resumed in 1975. 1975 was also significant for the Brazilian women's movement because of the U.N. Women's Year. Several large, influential feminist political action groups were formed, typically by upper class women with leftist views, although some church and union groups from lower classes also appeared. In 1979-1981, the coherence of these groups fell into schism and fragmentation, because of disagreements over the feminist political doctrines and roles, views on legality of abortion, and special interest groups such as lesbians. Another bitter dispute is opposition by leftist women to BEMFAM, the Brazilian Society of Family Welfare, which provides family planning for the poor: leftists oppose BEMFAM because it is supported by funds from "imperialist" countries such as the U.S. There are several types of feminists groups: those that emphasize health, sexuality and violence; those composed of lesbians; those originating from lower classes and unions; publicly instituted organizations. Brazilian law forbids discrimination against women holding public office, but in reality very few women actually do hold office, except for mayors of small towns and a few administrators of the Education and Social Security ministries. Political office in Brazil is gained by clientism, and since women rarely hold powerful positions in business, they are outsiders of the system. Brazilian women have achieved much, considering the low female literacy rate and traditional power system, but their

Brazilian chicken meat production chain:a 10-year overview

Full Text Available Brazil is the world's largest broiler meat exporter. Health control, knowledge and technology, as well as the natural aspects of the country are pointed out as the keys for the success of that product in the market. Brazilian broiler production grew significantly in the last decade; it creates jobs and has a significant social role in Brazilian economy. This study aimed at evaluating the Brazilian broiler meat supply chain from 2000 to 2010 using the social network analysis (SNA. Data from governmental and private sources were organized and analyzed. The focus of this study was the broiler production supply chain segment involving the hatchery, the broiler farm, the feed mill, the processing plant, and the government. The inputs considered were one-day-old chicks, pullet, feedstuff, and the infrastructure; and the outputs were broiler meat and taxes paid. The software UCINET was applied for calculating the structural attributes and indicators of the network. Results showed a relatively disorganized network in 2000 with the strongest tie between the farmer and the processing plant. The structural organization of the network improved until 2010. The density of the ties in the broiler meat production network increased steadily from 2000 to 2010 within a vertical cohesive supply chain structure. The success of Brazilian broiler meat production is attributed to the abundance of land, fertile soil, favorable climate, and the effort and investments in research and development by innovative companies in the last few years. The results of the present study showed that Brazilian broiler production evolved positively in the last ten years, and it was weakly influenced by international challenges.

This study describes the route followed by nursing in Brazil, through the foundation of nursing organizations and the emergence of nursing leaders and pioneers. To present the origins of modern nursing in Brazil, identifying the main nurse-leaders and analysing their performance for the creation and consolidation of the nursing organizations. It is a historical and social study with descriptive approach, to describe the process of Brazilian nursing professionalization and leadership through a literature review. The oldest nursing organization is the Brazilian Nursing Association that holds scientific and cultural activities. There are also nurses' unions and nursing specialty associations, such as the Brazilian Academy for the History of Nursing, and the Federal Nursing Council. The latter has compulsory membership for controlling nursing services according to the qualifications of the personnel. The very first school for nurses in the Nightingale system was created in São Paulo, 1894, at the Samaritan Hospital, and by the government in 1923, in Rio de Janeiro, for which American nurses, led by Ethel Parsons, sponsored by the Rockefeller Foundation, were essential for the creation of the Anna Nery Nursing School, still in operation within a federal university. Some nurses pioneered these works such as Edith Fraenkel, Maria Rosa Pinheiro, Amalia Carvalho and others. The work done by nursing leaders has brought to the profession a better status and made it more recognized by the society. © 2014 International Council of Nurses.

Brazilian sandy beaches: characteristics, ecosystem services, impacts, knowledge and priorities

Antonia Cecília Zacagnini Amaral

Full Text Available ABSTRACT Sandy beaches constitute a key ecosystem and provide socioeconomic goods and services, thereby playing an important role in the maintenance of human populations and in biodiversity conservation. Despite the ecological and social importance of these ecosytems, Brazilian sandy beaches are significantly impacted by human interference, chemical and organic pollution and tourism, as well as global climate change. These factors drive the need to better understand the environmental change and its consequences for biota. To promote the implementation of integrated studies to detect the effects of regional and global environmental change on beaches and on other benthic habitats of the Brazilian coast, Brazilian marine researchers have established The Coastal Benthic Habitats Monitoring Network (ReBentos. In order to provide input for sample planning by ReBentos, we have conducted an intensive review of the studies conducted on Brazilian beaches and summarized the current knowledge about this environment. In this paper, we present the results of this review and describe the physical, biological and socioeconomics features of Brazilian beaches. We have used these results, our personal experience and worldwide literature to identify research projects that should be prioritized in the assessment of regional and global change on Brazilian sandy beaches. We trust that this paper will provide insights for future studies and represent a significant step towards the conservation of Brazilian beaches and their biodiversity.

Full Text Available The Brazilian education system provides a specific form of organization for the inclusive education of students with disabilities. Law No. 9394 dated December 20, 1996, “Lei de diretrizes e bases da educação nacional”, presents in Chapter V the “educação especial" as a form of organization offered to students "portadores de Necessidades especiais”. Admission of students with disabilities in the Brazilian schools was characterized by several phases: the welfarist phase, the integration phase and the inclusion phase, which is the most recent one and now being debated. The presence of a special device fosters the differences, even when everybody enters the classbecause a separation perspective damps down all the procedural and design efforts towards a true integration, holding back collaboration and action sharing among teachers. We consider however effective an action that accompanies the gradual learning evolution mediating between the student with disabilities and peers, between him and the teachers, between him and the learning tools designed.

The Brazilian Soil Science Society (SBCS) is one of the oldest scientific societies in Brazil. It was created in October 1947 during the 1st Brazilian Meeting of Soil Science held at the headquarters of the Agricultural Chemistry Institute of Rio de Janeiro, at present the Soils Institute of the Brazilian Agricultural Research Centre. Its origin lies within the Interamerican Conference of Agriculture, Caracas, 1945, the 2nd Pan American Congress of Mining and Geology, Petropolis, Rio de Janeiro, 1946 and the 5th Brazilian Congress of Chemistry, Porto Alegre, 1947. Its first president was Álvaro Barcelos Fagundes, who was the only Brazilian participant at the 1st International Congress of Soil Science and Transcontinental Excursion held in United States of America, in 1927. At that time he was engaged in research work at the New Jersey Agricultural Experiment Station, at the Rutgers University where he did a doctorate under the guidance of Professor Selman Waksman. The society started with 47 members and presently has nearly 900 members. In its first phase the Brazilian Soil Science Society was housed at the Agricultural Chemistry Institute in Rio de Janeiro and its main activity was the biannual Brazilian Congress of Soil Science. In 1975 its headquarters moved to the Agronomic Institute of Campinas with the creation of its executive board and the start of publication of the Brazilian Journal of Soil Science (1977) as well as the society bulletin (1976). In 1997 its executive office moved to the Soils Department at the Federal University of Viçosa. Nowadays it has a structure similar to the one from the IUSS: the society is organized in four divisions (Soil in space and time, Soils properties and processes, Soil use and management and Soil, environment and society) which encompass 14 technical commissions and eight State or Regional nuclei. The Brazilian Congresses of Soil Science happen without interruption since 1947. The first one had had 72 participants that

Use of solid phase microextraction to identify volatile organic compounds in brazilian wines from different grape varieties

Directory of Open Access Journals (Sweden)

Natália Cristina Morais Fernandes

Full Text Available Abstract The Brazilian wine industry has shown significant growth in recent years and the insertion of new concepts, such as geographical indications as signs of quality, has placed Brazil in tune with the tendencies of world wine production. The aim of this work was to apply the Solid Phase Microextraction technique in combination with Gas Chromatography-Mass Spectrometry to study Brazilian wines made from different grape varieties, in order to separate and identify their volatile organic compounds. These substances were identified by comparisons between the spectra obtained with those presented in the NIST library database, and by comparisons with linear retention indices and literature data. The amounts of the compounds were calculated based on the total peak areas of the chromatograms. Forty-seven volatile compounds were identified and grouped into alcohols, aldehydes, fatty acids, esters, hydrocarbons, ketones and terpenes. Most of them belonged to the ester function, conferring a fruity aroma on the wines. The alcohols may have originated from the yeast metabolism, contributing to the alcoholic and floral aromas. Ethyl lactate, 1-hexanol and diethyl maleate were identified in all the varieties, except Merlot. Decanal, methyl citronellate, (E-2-hexenyl-3-methylbutyrate were only found in Merlot, while 2,3-butanediol was only present in the Tannat wines. 2-Phenylethanol was present in all varieties and is recognized as giving pleasant rose and honey attributes to wines. This study showed that the volatile profile of red wines is mainly characterized by esters and higher alcohols. The statistical analysis of the comparison of averages showed a greater amount of averages significantly different in the relative areas of Merlot wine. The Principal Component Analysis showed one grouping composed only of the Merlot wine samples, and this was probably related to the existence of the volatile organic compounds that were specifically identified in

Publication in a Brazilian journal by Brazilian scientists whose papers have international impact.

Meneghini, R

2010-09-01

Nine Brazilian scientists with an outstanding profile of international publications were invited to publish an original article in the same issue of a Brazilian Journal (Anais da Academia Brasileira de Ciências). The objective was to measure the impact of the papers on the number of citations to the articles, the assumption being that these authors would carry their international prestige to the Brazilian periodical. In a 2-year period there was a larger number of citations of these articles compared to others published in the same journal. Nevertheless, the number of citations in Brazilian journals did not equal the number of citations obtained by the other papers by the same authors in their international publications within the same 2-year period. The reasons for this difference in the number of citations could be either that less significant invited articles were submitted or that it was due to the intrinsic lack of visibility of the Brazilian journals, but this could not be fully determined with the present data. Also relevant was a comparison between the citations of Brazilian journals and the publication in Brazilian journals by these selected authors. A clear imbalance due to a remarkable under-citation of Brazilian authors by authors publishing in Brazilian journals raises the possibility that psychological factors may affect the decision of citing Brazilian journals.

Full Text Available This paper aims to map the codes of behaviors and manners in social relations and in the recent changes in sport organization in Brazil. Ideological, social, cultural, political and economic dimensions are given relevance here as a methodology in that they organize statements. In bibliographical sources interpreting sociologic discourses and in the outline of Brazilian society development and evolution we observe several characteristics pertaining to self-restraint and emotion control through sport. In the economic sphere, we evidence an explanation of social changes resulting from Brazil’s late development process. However, drawing from the empirical theory, preliminary results show the recent sociocultural phenomenon of soccer as a factor to be considered in the formation of Brazilian social behavior.

Ten women, victims of gender violence, took part in a workshop developed by non-governmental organization for African-Brazilian women Maria Mulher, which gives assistance to women living in Vila Cruzeiro do Sul, in the city of Porto Alegre. The main objective of the research was to debate questions related to gender and violence, making use of stories and histories related to the feminine, specifically African-Brazilian stories. Five meetings were held, where the women told and were told stories, took part in group discussions, experiences and rituals. The workshops gave those women a space where they could tell and hear stories, take part in the rituals of the orixás [African-Brazilian deities] of the black culture and tell their personal histories using those experiences. This intervention was an attempt at invoking different subjective experiences, and made it possible to empower the women who took part in the research, contributing for the rescue of the individual and collective memory of this group.

By means of scientometric indicators, this study investigated the characteristics of scientific production and research collaboration involving zebrafish (Danio rerio) in Brazilian Science indexed by the Web of Science (WoS). Citation data were collected from the WoS and data regarding Impact Factor (IF) were gathered from journals in the Journal Citation Reports. Collaboration was evaluated according to coauthorship data, creating representative nets with VOSviewer. Zebrafish has attained remarkable importance as an experimental model organism in recent years and an increase in scientific production with zebrafish is observed in Brazil and around the world. The citation impact of the worldwide scientific production is superior when compared to the Brazilian scientific production. However, the citation impact of the Brazilian scientific production is consistently increasing. Brazil does not follow the international trends with regard to publication research fields. The state of Rio Grande do Sul has the greatest number of articles and the institution with the largest number of publications is Pontifícia Universidade Católica do Rio Grande do Sul. Journals' average IF is higher in Brazilian publications with international coauthorship, and around 90% of articles are collaborative. The Brazilian institutions presenting the greatest number of collaborations are Pontifícia Universidade Católica do Rio Grande do Sul, Universidade Federal do Rio Grande do Sul, Fundação Universidade Federal de Rio Grande, and Universidade de São Paulo. These data indicate that Brazilian research using zebrafish presents a growth in terms of number of publications, citation impact, and collaborative work.

Full Text Available Abstract Background Differences in sex hormone levels among populations might contribute to the variation in breast cancer incidence across countries. Previous studies have shown higher breast cancer incidence and mortality among Japanese Brazilians than among Japanese. To clarify the difference in hormone levels among populations, we compared postmenopausal endogenous sex hormone levels among Japanese living in Japan, Japanese Brazilians living in the state of São Paulo, and non-Japanese Brazilians living in the state of São Paulo. Methods A cross-sectional study was conducted using a control group of case-control studies in Nagano, Japan, and São Paulo, Brazil. Participants were postmenopausal women older than 55 years of age who provided blood samples. We measured estradiol, estrone, androstenedione, dehydroepiandrosterone sulfate (DHEAS, testosterone and free testosterone by radioimmunoassay; bioavailable estradiol by the ammonium sulfate precipitation method; and sex hormone-binding globulin (SHBG by immunoradiometric assay. A total of 363 women were included for the present analyses, comprising 185 Japanese, 44 Japanese Brazilians and 134 non-Japanese Brazilians. Results Japanese Brazilians had significantly higher levels of estradiol, bioavailable estradiol, estrone, testosterone and free testosterone levels, and lower SHBG levels, than Japanese. Japanese Brazilians also had significantly higher levels of bioavailable estradiol, estrone and DHEAS and lower levels of SHBG and androstenedione than non-Japanese Brazilians. Levels of estradiol, testosterone and free testosterone, however, did not differ between Japanese Brazilians and non-Japanese Brazilians. These differences were observed even after adjustment for known breast cancer risk factors. We also found an increase in estrogen and androgen levels with increasing body mass index, but no association for most of the other known risk factors. Conclusions We found higher levels of

Full Text Available The study seeks to understand the interests of the capital intellectuals’ movement for Brazilian higher education. We chose a bibliographical study and document, besides using the method of Marxist dialectical analysis to understand reality as a complex totality, an articulated whole. It was verified that intellectuals play a decisive role in taking action on the direction of Brazilian higher education policy, operating directly in the culture of the state university as well as orchestrating a political-juridical framework for the expansion of private higher education institutions. At the limit, intellectuals are not only manifested as individual subjects; however, as organized collective subjects, for example, international financial capital organizations with their orientations towards peripheral countries express intellectuals of capital in their parasitic phase.

ABSTRACT Objective To evaluate the psychometric properties of the seven theoretical models proposed in the literature for European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), when applied to a sample of Brazilian cancer patients. Methods Content and construct validity (factorial, convergent, discriminant) were estimated. Confirmatory factor analysis was performed. Convergent validity was analyzed using the average variance extracted. Discriminant validity was analyzed using correlational analysis. Internal consistency and composite reliability were used to assess the reliability of instrument. Results A total of 1,020 cancer patients participated. The mean age was 53.3±13.0 years, and 62% were female. All models showed adequate factorial validity for the study sample. Convergent and discriminant validities and the reliability were compromised in all of the models for all of the single items referring to symptoms, as well as for the “physical function” and “cognitive function” factors. Conclusion All theoretical models assessed in this study presented adequate factorial validity when applied to Brazilian cancer patients. The choice of the best model for use in research and/or clinical protocols should be centered on the purpose and underlying theory of each model. PMID:29694609

Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of non-melanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection.

To identify limiting factors in the management of pharmaceutical services in the primary health care provided by the Brazilian Unified Health System (SUS). This study was based on the data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), and it was conducted by interviews with professionals responsible for pharmaceutical services in Brazilian cities, in 2015. To identify the management limiting factors, we considered the organizational, operational, and sustainability indicators of the management. For the analyses, we included the weights and structure of analysis plan for complex samples. The results were expressed by frequencies and measures of central tendency with 95% confidence interval, considering the Brazilian geographic regions. We identified the following limiting factors: lack of pharmaceutical services in the Municipal Health Secretariat organization chart (24%) and in the health plan (18%); lack of participation of managers in the Health Board and the absence of reference to this topic in the agenda of meetings (58.4%); lack of financial autonomy (61.5%) and lack of knowledge on the available values (81.7%); lack of adoption of operational procedures (about 50%) for selection, scheduling, and acquisition; and the fact that most professionals evaluate the organization of pharmaceutical services as good and great (58.8%), despite the worrisome indicators. Pharmaceutical services management is currently supported by a legal and political framework that should guide and contribute to improve the pharmaceutical services in the Brazilian Unified Health System primary health care. However, there is a mismatch between the goals established by these guidelines and what is actually happening.

Proposal of a Methodology of Stakeholder Analysis for the Brazilian Satellite Space Program

Mônica Elizabeth Rocha de Oliveira

2012-03-01

Full Text Available To ensure the continuity and growth of space activities in Brazil, it is fundamental to persuade the Brazilian society and its representatives in Government about the importance of investments in space activities. Also, it is important to convince talented professionals to place space activities as an object of their interest; the best schools should also be convinced to offer courses related to the space sector; finally, innovative companies should be convinced to take part in space sector activities, looking to returns, mainly in terms of market differentiation and qualification, as a path to take part in high-technology and high-complexity projects. On the one hand, this process of convincing or, more importantly, committing these actors to space activities, implies a thorough understanding of their expectations and needs, in order to plan how the system/organization can meet them. On the other hand, if stakeholders understand how much they can benefit from this relationship, their consequent commitment will very much strengthen the action of the system/organization. With this framework in perspective, this paper proposes a methodology of stakeholder analysis for the Brazilian satellite space program. In the exercise developed in the article, stakeholders have been identified from a study of the legal framework of the Brazilian space program. Subsequently, the proposed methodology has been applied to the planning of actions by a public organization.

Full Text Available Brazil is the 5th largest country in the world and its present population, in excess of 190 million, is highly heterogeneous, as a result of centuries of admixture between Amerindians, Europeans and Sub-Saharan Africans. The estimated individual proportions of biogeographical ancestry vary widely and continuously among Brazilians, most individuals - irrespective of self-identification as White, Brown or Black, the major categories of the Brazilian Census race/color system - having significant degrees of European and African ancestry, while a sizeable number display also Amerindian ancestry. These features have important pharmacogenetic (PGx implications: first, extrapolation of PGx data from relatively well-defined ethnic groups is clearly not applicable to the majority of Brazilians; second, the frequency distribution of polymorphisms in pharmacogenes (e.g. CYP3A5, CYP2C9, GSTM1, ABCB1, GSTM3, VKORC, etc varies continuously among Brazilians and is not captured by race/color self-identification; third, the intrinsic heterogeneity of the Brazilian population must be acknowledged in the design and interpretation of PGx studies in order to avoid spurious conclusions based on improper matching of study cohorts. The peculiarities of PGx in Brazilians are illustrated with data for different therapeutic groups, such as anticoagulants, HIV-protease inhibitors and nonsteroidal antinflammatory drugs, and the challenges and advantages created by population admixture for the study and implementation of PGx are discussed. PGx data for Amerindian groups and Brazilian-born, first generation Japanese are presented to illustrate the rich diversity of the Brazilian population. Finally, I introduce the reader to the Brazilian Pharmacogenetic Network or Refargen (www.refargen.org.br, a nationwide consortium of research groups, with the mission to provide leadership in PGx research and education in Brazil, with a population health impact.

Full Text Available This paper analyzes self-perceptions of media roles and ethics of a sample of Brazilian journalists and compares them with American and French journalists. French and American styles of journalism have had major infl uences on Brazilian newspapers at different points in time. The study included a self-administered survey with 402 journalists working for 13 leading news organizations and personal interviews with renowned journalists of Sao Paulo- Brazil’s main media hub.  The typical Brazilian journalist in this study was a young white middle-class male, politically left leaning oriented, more likely to be married and Catholic. Respondents held a pluralistic view regarding media roles and expressed higher tolerance of controversial journalistic practices compared to that of their counterparts. Findings are in line with the social-political environment in which journalists operate. They do not enjoy special rights of access to government information, tend to distrust public institutions and have still been adapting to press freedom since the country’s redemocratization.

Life expectancy (LE) refers to the number of years that an individual is expected to survive. Emphasis is frequently placed on the relationship between LE and the conditions under which a population lives, but fewer studies have investigated the relationship between stress factors associated with specific professions and their effects on LE. The aim of this study is to evaluate Brazilian neurosurgeons' life expectancies (BNLEs) and compare them with those of physicians (both Brazilian and foreign) from other fields, as well as with Brazilian nondoctors. The Brazilian Society of Neurosurgery death registry was used to obtain data that compared LEs from non-neurosurgeon physicians, as described in the national and international literature. BNLEs were also compared with the LEs of Brazilian citizens. Fifty-one neurosurgeons died between 2009 and 2016. All were males. The mean age at death was 68.31 ± 17.71 years. Among all-cause mortality, the breakdown was 20% cardiovascular diseases, 39% malignancies, 10% external factors, 6% gastrointestinal disorders, 12% neurologic illnesses, and 14% unknown causes. BNLE was shorter than LE of male Brazilian citizens. LE was similar among neurosurgeons and other doctors but shorter compared with Brazilian citizens. Further research is needed to provide data that can add to and confirm these results. Copyright © 2018 Elsevier Inc. All rights reserved.

1995-01-01

This work covers the theory and construction of a Mathematical Phantom of the Brazilian, to be used in internal dosimetry. To obtain this it was necessary to develop antropometric data of mass and height for Brazilian man between 20 and 40 years old. Through Monte Carlo Method, and applying the Specific Absorbed Fraction (SAF) formalism, it was possible determine the fraction internal organs such as bones, skin and total body. The results obtained from SAF are primordial in nuclear medicine and great value in the calculation of the dose received by workers exposed and in accidental cases, to a rapid evaluation of the received by a simple person. Through SAF, the references obtained for the Brazilian man, can be noted when compared to the phantom calculated by Snyder, which proposed to represent the international reference man, showed by ICRP-23 publication, that the determined SAF of the whole body does not exceed 15% between the two phantoms, agreeing with the allowed international norms error margin permitted. The differences between the two models appear, when the numbers are presented for individual organs, where the emission origin are the lungs and taken as target, the red and yellow marrows, for an energy of 10 KeV. The result obtained is that these two marrows receive 64% more absorbed fractions in the Brazilian model than in the international model. These numbers are considered trustfully because the coefficient of variation does not exceed 7%, value that in under 50%, which makes the coefficient of variation not trustfully, this is considered out of the normal distribution. Facts like these and may others, showed in this work, determine the necessity to calculate a specific mathematical model for the Brazilian man. (author). 51 refs., 40 figs., 9 tabs

The purpose of this work is to elucidate the reasons that stimulate a contemporary Brazilian composer to write music for the organ. The methodology includes: (1 interviews with nine composers, (2 analysis of the collected data, (3 analysis of the musical style, and (4 aesthetical conceptions present in the works. The chosen pieces were composed between 1990-2005 and they are studied in more detail in the research project “Brazilian organ music: history, analysis, aesthetical appreciation and didactic evaluation” supervised by Any Raquel Carvalho. Partial results consider the fact that only three out of nine the composers are organists. Nevertheless, their works demonstrate knowledge of specific details of the instrument, an important factor for this genre. For the remaining composers, the organ does not represent the main focus of their musical output --most of them have composed only one work for this medium.

2012-01-01

This article describes a proposal for analyzing the performance of public Brazilian hospitals using financial and non-financial rates (i.e., operational rates), and thereby highlights the effectiveness (or otherwise) of the financial management of organizations in this study. A total of 72 hospitals in the Brazilian Unified Health Care System (in Portuguese, Sistema Unico de Saúde-SUS), were selected for accessibility and completeness of their data. Twenty-six organizations were used for the study sample, consisting of entities that had publicly disclosed financial statements for the period from 2008 (in particular, via the Internet) and whose operational data could be found in the SUS database. Our proposal, based on models using the method of Data Envelopment Analysis (DEA), was the construction of six initial models that were later compiled into a standard model. The relations between the rates that comprised the models were based on the variables and the notes of: Schuhmann, McCue and Nayar, Barnum and Kutzin, Younis, Younies, and Okojie, Marinho, Moreno, and Cavalini, and Ersoy, Kavuncubasi, Ozcan, and Harris II. We put forward an enhanced grant proposal applicable to Brazil aiming to (i) confirm or refute the rates that show the effectiveness or ineffectiveness of financial management of national hospitals; and (ii) determine the best performances, which could be used as a reference for future studies. Obtained results: (i) for all financial indicators considered, only one showed no significance in all models; and (ii) for operational indicators, the results were not relevant when the number of occupied beds was considered. Though the analysis was related to only services provided by SUS, we conclude that our study has great potential for analyzing the financial management performance of Brazilian hospitals in general, for the following reasons: (i) it shows the relationship of financial and operational rates that can be used to analyze the performance of

Sexuality education has been valued since the 1960s in medical schools worldwide. Although recent studies reaffirm the importance of incorporating sexuality into medical education, there are data gaps concerning how this happens in Brazil. To understand how Brazilian medical school professors teach sexuality in undergraduate courses. An exploratory, cross-sectional descriptive study was conducted. A total of 207 professors from 110 Brazilian medical schools responded to an online semistructured questionnaire about the characteristics of the sexuality-related topics offered. The main variables assessed were contact hours devoted to sexuality, disciplines in which sexuality topics were taught, sexuality-related course titles, and sexuality-related topics addressed. Questionnaires were tabulated and analyzed using descriptive statistics for frequency distribution. The response rate to the questionnaire was 77.2%. Almost all professors (96.3%) addressed sexuality-related topics mainly in the third and fourth years as clinical disciplines, with a 6-hour load per discipline. Gynecology was the discipline in which sexuality-related topics were most often taught (51.5%), followed by urology (18%) and psychiatry (15%). Sexuality-related topics were addressed mainly in classes on sexually transmitted diseases and AIDS (62.4%) and on the anatomy and physiology of the reproductive system (55.4%). About 25% of the professors reported teaching courses with a sexuality-related title. There was emphasis on the impact of diseases and sexual habits (87.9%) and sexual dysfunction (75.9%). Less than 50% of professors addressed nonnormative sexuality or social aspects of sexuality. The teaching of sexuality in Brazilian medical schools occurred in a nonstandardized and fragmented fashion across several disciplines. The topic was incorporated with an organic and pathological bias, with a weak emphasis on the social aspects of sexuality and the variety of human sexual behaviors. The

Full Text Available The internationalization of Brazilian companies brings a new reality: the need for implementation of global projects that bring, in turn, the challenge of managing multicultural teams. Since this is a recent phenomenon with little theoretical development, this study sought to understand the relationships between cultural characteristics and management teams of global projects in Brazilian multinationals. To carry this discussion forward, we studied six cases of Brazilian multinational companies, with the aim of deepening the understanding of the management of global teams, involving the planning, deployment, development and management of human resources. Among the projects studied, it was found that there is very little concern with the specific issue of multiculturalism and little inter-cultural incentive to the development of team members, which ends up hindering the construction of a global mindset, important for the Brazilian multinational companies to perform successfully abroad. Faced with this situation, each of the managerial processes mentioned were presented with a number of actions to be undertaken by the project manager in three different dimensions: the project itself, the organization and the global environment. The work contributes, thus, to enable Brazilian multinational companies to manage their global teams in order to maximize the advantages of global teams, such as increased creativity and innovative capacity, but avoid the problems that multiculturalism can bring, ranging from conflicts between people to project failure.

THE INSTITUTIONAL BASIS OF GERMAN-BRAZILIAN COMMUNITIES (PICADAS: THE COMMONS AND SOCIAL CAPITAL

Full Text Available The historiography of German immigration to Brazil knows just a little about the structures that animated social life in Germany before the process of immigration. Therefore, the americanização of the German-Brazilian settlers is considered solely from the perspective of the host society, creating a gap that needs to be filled in order to understand another dimension of German immigration, the European side and influence over it. In this sense, it is possible to perceive that generally the social origins of German-Brazilian settlers is linked to a village context experience, especially those who came from Western and Southwestern Germany. Historically these villages were social organizations able to control natural and economic resources under their jurisdictions with a great political and economic autonomy. The so called commons were a feature of the German agrarian history, and its institutions of participatory, mutual, protectionist, communal management had the effect to generate social capital, one social attribute that supported the formation of the German-Brazilian communities in Southern Brazil. Thus, the German-Brazilian communities were forged under a solid institutional tradition and under a substrate of social capital, facilitating the emergence of autonomous and cooperative behaviors that resulted on the communitarian structures and on the associativism phenomenon. The method was the analytical descriptive based on research in primary sources in Brazilian and German Archives.

Full Text Available Competitive intelligence (CI is a systematic and ethical collection, analysis, dissemination and management of information about the external environment that may affect the plans, decisions and operations of the organization. Knowledge management (KM can be seen as a tool to promote organizational knowledge through the use of activities designed to identify, create, store, share and use knowledge. Companies face a challenge in the era of knowledge, it is the extraction and management of knowledge produced by people in the organization. CI and KM combined generates organizational intelligence. The exploratory study, based on literature and multicase study, we sought to identify best practices in processes of CI and KM in Brazilian companies. We identified practices related to the CI design process, the stages of the CI, the use of networks, and knowledge management. We also identified, points of attention on the internal/external organizational environment.

Full Text Available The economic literature relative to Brazilian labor market informality is very disperse and presents a significant lack of organization. In that sense, the purpose of this paper is to organize and discuss on a systematic way the main pieces of literature concerning informality in the Brazilian labor market using, whenever it is possible, the international literature as a comparison point for the existing results relative to Brazil's experience. More specifically, questions related to wage differentials between formal and informal workers, labor market segmentation and the effect of institutions on the informal sector are emphasized.

The construction of the social problem of violence in brazilian football: domination and resistance

Full Text Available In this paper, I aimed to answer the following question: how the claims-makers of the social problem of violence in Brazilian football symbolically construct the conditions of this problem, the actors involved in it and their solutions and how these symbolic constructions reinforce or, on the contrary, undermine relations of domination? Therefore, I referred to research findings that I have been developing since 2008. Besides, I considered my experiences during my participation in the public debate about violence in Brazilian football. Among other things, I concluded that some of these symbolic constructions have kept the organized group of supporters and the poor supporters under a condition of domination. At the same time, I indicated that they have motivated practices of resistance, such as the creation of representative associations of organized group of supporters.

Brazilian jeitinho versus Chinese guanxi: investigating their informal influence on international business.

Directory of Open Access Journals (Sweden)

Cláudio V. Torres

2015-08-01

Full Text Available The Brazilian jeitinho and the Chinese guanxi are considered indigenous forms of informal influence. The first can be described as behavior tactics aimed at resolving social problems. The latter is broadly described as achieving goals through the use of social networks. These influence processes were chosen because they are commonly used in business negotiations in Brazil and China. Thus, understanding their peculiarity is fundamental for the management of organizations involved in business in those two cultures. Therefore, we seek to determine whether such influence processes differ, as it is possible that a process said to be indigenous to a particular cultural context might be, in fact, also found elsewhere. To investigate their uniqueness and the relationship between them, two studies were carried out. In both studies, participants rated representativeness, typicality and positivity of social scenarios, besides completing a 21-item version of the Schwartz’s Portrait Value Survey and a scale regarding attitudes towards corruption. Data were analyzed by a series of mean difference tests and stepwise regressions, separately for each nation, and the results are presented by sample. There were two samples: university students’ sample (with 266 Brazilian and 220 Chinese and managers’ sample (with 101 Singapore Chinese and 246 Brazilian. Brazil scored significantly higher on conservation and selfenhancement values when compared to China. Chinese respondents perceived the guanxi scenarios as more typical of what happens in China than the jeitinho scenarios, with a reverse pattern being observed for Brazilians. Although Brazilian respondents evaluated jeitinho less positively than Chinese respondents evaluated guanxi scenarios, but they also did perceive jeitinho as more positive than. For the managers’ samples, it was observed that Brazilians had a significantly lower score on attitudes toward business corruptibility when compared to Chinese

Morpho-anatomical features of underground systems in six Asteraceae species from the Brazilian Cerrado.

Appezzato-da-Glória, Beatriz; Cury, Graziela

2011-09-01

In the Brazilian Cerrado (neotropical savanna), the development of bud-bearing underground systems as adaptive structures to fire and dry periods can comprise an important source of buds for this ecosystem, as already demonstrated in the Brazilian Campos grasslands and North American prairies. Asteraceae species from both woody and herbaceous strata have subterranean organs that accumulate carbohydrates, reinforcing the adaptive strategy of these plants to different environmental conditions. This study aims to analyse the morpho-anatomy of underground systems of six species of Asteraceae (Mikania cordifolia L.f. Willd., Mikania sessilifolia DC, Trixis nobilis (Vell.) Katinas, Pterocaulon alopecuroides (Lam.) DC., Vernonia elegans Gardner and Vernonia megapotamica Spreng.), to describe these structures and to verify the occurrence and origin of shoot buds, and to analyse the presence of reserve substances. Individuals sampled in Cerrado areas in São Paulo State showed thick underground bud-bearing organs, with adventitious or lateral roots and presence of fructans. Xylopodium was found in all studied species, except for Trixis nobilis, which had stem tuber. The presence of fructans as reserve, and the capacity of structures in the formation of buds indicate the potential of herbaceous species of Asteraceae in forming a viable bud bank for vegetation regeneration in the Brazilian Cerrado.

Understanding organization and institutional changes for management of environmental affairs in the Brazilian petroleum sector

International Nuclear Information System (INIS)

Oliveira, J.A.P. de

2003-01-01

This article analyzes how governments and an oil company adapted their institutional and organization frameworks to manage actual and potential environmental impacts of oil-related activities in Brazil. Two major factors are important for understanding these changes. First, the monopoly of the state to explore and produce oil is over. Foreign companies have entered Brazil and increased the competitiveness of the oil sector. Second, major oil spills into waterways in recent years resulted in severe fines and an increasing outcry from government and civil society representatives for greater control over oil activities. These two factors raised a debate about what are, or should be, the roles of various stakeholders involved in controlling oil activities and their impacts on the environment. Legislative changes assigned different roles to the state oil company, to a newly created regulatory agency, to the Navy and to federal and state environmental agencies. Because many of the legal changes were not well defined, accountability among institutional actors remained unclear and institutional conflicts about who is accountable for what were likely to occur. As well, government organizations, public prosecutors, media and civil society increasingly influenced the regulation of both government agencies and companies. As a result, these responded to regulatory change and market forces by changing their relations with external stakeholders and their organizational arrangements for environmental management. This article identifies some of the institutional conflicts in selected case studies from the oil industry, the difficulties in clarifying regulatory roles within the industry, and responses in terms of the environmental strategies of regulatory bodies and oil companies, specifically the Brazilian state company, Petrobas.

Full Text Available The Brazilian savannah (cerrado is an area of expansion of agribusiness. Among the various environmental changes related to deforestation of the savannah stand out impacts related to soil organic matter such as the imbalances in stocks and the changing nature of soil organic carbon. The objective of these study was to evaluate changes in nature (δ13C and quantity (C% of soil carbon after conversion of the dense savannah vegetation in areas under different lan duses (pasture, soybeans, corn / soybean rotation, management (conventional and zero tillage developed in soils with different textural characteristics. The results showed that the average data set of non–managed grazing was the most distanced from the value obtained in cerrado soil. Another factor that determined the lowest concentrations of organic carbon was the presence of sandy soil. The results showed that the carbon C4 grasses in areas occupied by pastures, with or without management, replaced the original C3 carbon originated by cerrado. In the areas of conventional tillage, and no–tillage soybean, and consortium soybean/corn, no clear trend of impoverishment or enrichment of carbon and the carbon substitution as well as the incorporation of different nature of the carbon could be found.

Stranding Events of Kogia Whales along the Brazilian Coast.

Directory of Open Access Journals (Sweden)

Jailson F Moura

Full Text Available The genus Kogia, which comprises only two extant species, Kogia sima and Kogia breviceps, represents one of the least known groups of cetaceans in the global ocean. In some coastal regions, however, stranding events of these species have been relatively common over the last decades. Stranding provides the opportunity to investigate the biology of these cetaceans and to explore the epidemiological aspects associated with the mortality of the organisms found on the beach. A number of disturbances (including pelagic fisheries, chemical pollution, boat strikes, and noise pollution have been confirmed to pose a particular threat to the Kogia species. However, no study has yet investigated potential relationships between environmental conditions and stranding events. Here we analyse how a collection of environmental, physical, and biological variables, such as wind, sea surface temperature (SST, water depth, and chlorophyll-a, correlate to Kogia stranding events along the Brazilian coast. The results of our statistical analyses suggest that K. sima is more likely found in warm tropical waters, which provide an explanation for the high frequency of stranding in northeastern Brazilian coast. In contrast, K. breviceps appears to have a preference for temperate and productive waters. Wind speed results to be also an important factor for predicting Kogia strandings in Brazilian coast. Additionally, literature information in combination with our own data and analyses of stomach contents confirms that oceanic cephalopods constitute the primary nutritional source of both Kogia species. By using the available information as a qualitative proxy for habitat preference and feeding ecology, our study provides a novel and comprehensive assessment of Kogia stranding data in relation to environmental conditions along the Brazilian coast.

The sample comprised 1,772 periapical radiographs from 443 subjects (219 men, 224 women that were organized into 12 groups according to sex (men or women and age (20-29, 30-39, 40-49, 50-59, 60-69, and 70 years and older. The films were analyzed using the criteria described by Cameriere et al. (2004 and Adobe Photoshop®. We obtained a mean error of 8.56 (SD = 5.80 years for tooth 13, 7.99 (SD = 5.78 years for tooth 23, 8.38 (SD = 6.26 years for tooth 33, and 8.20 (SD = 6.54 years for tooth 43. When teeth were combined in the analysis, we observed lower mean errors. The Brazilian formula developed from this sample group was more accurate than Cameriere’s formula. However, other factors must be considered to improve age estimates in adults.

The sorption from aqueous solution of ten Brazilian soil types of four organochlorine, two organophosphorus and one carbamate insecticide was determined in the laboratory using gas chromatographic and radiometric techniques. Measurements showed that soils richest in organic matter, sorbed all substances except aldrin more strongly than the other soils. DDT was the most and aldrin the least sorbed organochlorine pesticide, being dieldrin sorbed two to four times more strongly than aldrin. Sorption of lindane varied in different soils. The organophosphate insecticides malathion and parathion were strongly sorbed in the soils richest in organic matter and weakly sorbed in the poorest soils heing moderately sorbed by the other soils. Sorption of carbaryl by all soils is small. Lindane was desorbed from the soil richest in organic matter and the extent of desorption was dependent on the sorption time. (Author) [pt

The use of rigorous scientific methods has contributed towards developing scientific articles of excellent methodological quality. This has made it possible to promote their citation and increase the impact factor. Brazilian periodicals have had to adapt to certain quality standards demanded by these indexing organizations, such as the content and the number of original articles published in each issue. This study aimed to evaluate the methodological adequacy of two Brazilian periodicals within the field of cardiology that are indexed in several databases and freely accessible through the Scientific Electronic Library Online (SciELO), and which are now indexed by the Web of Science (Institute for Scientific Information, ISI). Descriptive study at Brazilian Cochrane Center. All the published articles were evaluated according to merit assessment (content) and form assessment (performance). Ninety-six percent of the articles analyzed presented study designs that were adequate for answering the objectives. These two Brazilian periodicals within the field of cardiology published methodologically adequate articles, since they followed the quality standards. Thus, these periodicals can be considered both for consultation and as vehicles for publishing future articles. For further analyses, it is essential to apply other indicators of scientific activity such as bibliometrics, which evaluates quantitative aspects of the production, dissemination and use of information, and scientometrics, which is also concerned with the development of science policies, within which it is often superimposed on bibliometrics.

Full Text Available The present work deals with the Brazilian exports of sawnwood of non-coniferous, veneer sheets and plywood, from 1961 to 2002. The data regarding the three studied products, sawnwood of non-coniferous, veneer sheets and plywood, were joined through the method of Fisher so that an econometric evaluation of the market of the three products could be carried out. Supply and demand models of the Brazilian exports were specified. The results were satisfactory and they match with the literature. The supply of exports presented a positive answer in relation to the exporter's remuneration, to the production, to the use of the installed capacity (cycles of domestic economical activity and to the tendency, and negative in relation to the internal demand. The demand for the Brazilian exports was influenced positively by the world income, participation index and tendency, and negatively for the relative price. The low elasticity-price of the found demand can have implications in the conservation of the Brazilian forest resources because the exporters can increase the prices, reduce the amounts and still increase the incomes.

Full Text Available http://dx.doi.org/10.5007/2175-7968.2013v1n31p119 Jorge Amado (1912-2001 is the most translated Brazilian writer and the literary figure that has shaped the reception of Brazilian literature in the world.  He is credited with opening the international literary market to the post-dictatorship generation of Brazilian writers.  Yet Amado is also a controversial figure.  The debate around him is sparked by what some believe is sexual and ethnic stereotyping in his post-1958 works and the reinforcement of "paternalistic "racial views. His reception therefore is mixed. For his English-language readers, he is a fascinating source of exotic and titillating narratives about the vast, unknown country of Brazil, and for Brazilians he is either a "great ambassador of Brazilian culture around the world" or a faux populist who disguises sexist and racist attitudes behind charming prose. This paper will address Amado's literary career, his unique contributions to Brazilian letters, the challenges of translating his work, and his influence on the production of a new Brazilian literature for export

Pedro Lucas de Resende Melo

2015-04-01

Full Text Available The primary goal of this paper is to comprehend the fundamental organizational differences between Brazilian franchise chains that only operate in the home market and Brazilian franchise chains that operate internationally. The sample chosen for this study comprehends 96 Brazilian franchises operating in the home market and 67 franchises with international operations; logistic regression was used to analyze data obtained from these sources. Our findings suggest that the development of a brand in international operations can be strategic for certain Brazilian franchise chains; this seems to be, however, a scarce resource for many franchises and it could be developed through international operations. With regard to the fees charged, the outcomes demonstrate that Brazilian franchises with international operations tend to charge lower fees from its franchisees to install new units. Regarding the monitoring and control of franchises, there is evidence that the monitoring capability is one of the determining factors in the development of Brazilian franchises international operations.

Methods All the references of articles published in 2011 by the journals Acta Ortopédica Brasileira, Coluna/Columna and Revista Brasileira de Ortopedia were evaluated to as certain how many of these came from Brazilian journals and how many from foreign journals. Results 3813 references distributed among 187 articles were analyzed. Out of this total, 306 (8.02%) were from Brazilian journals. There was no difference between the three journals analyzed. There were 76 articles (40.64%) without any citations of articles in Brazilian journals and only two articles (1%) cited more Brazilian articles than articles published elsewhere. Conclusion There is a need for Brazilian researchers to cite articles from Brazilian journals more often. PMID:26229879

Futebol mulato: racial constructs in Brazilian football

Directory of Open Access Journals (Sweden)

Tiago Fernandes Maranhao

2011-05-01

Full Text Available The aim of this paper is to review Gilberto Freyre’s ideas about futebol mulato and the way these ideas have spread the notion of the Brazilian mulatto as a symbol of a ‘racial democracy’, unique in Brazil, around the world. The notion first appeared in 1938 in an article by Freyre for the Diários Associados, an important Brazilian newspaper. Football (soccer was employed by Freyre as the special arena where the multiracial Brazilian nation could shine and show the world a different way of being, opposed to the white and ‘rational’ way of European football. In Freyre’s work, the so-called ‘football-art’ was compared to poetry, while the European style was equated with prose. This essay argues that Freyre’s ideas were useful in constructing the Brazilian identity, a nation of harmony in all its aspects, including the area of race, and how the idea of the mulatto has been used to minimise social disparities within Brazilian society. Freyre’s ideas remain contemporary; many Brazilian intellectuals still refer to these concepts. As well, the press in this huge country, and especially in World Cup years, uses the concepts of mulatto and football-art to characterize Brazil and differentiate it from other countries.

Full Text Available Plethodontid salamanders of genus Bolitoglossa constitute the largest and most diverse group of salamanders, including around 20% of living caudate species. Recent studies have indicated the occurrence of five recognized species in the Brazilian Amazon Rainforest. We present here the first cytogenetic data of a Brazilian salamander, which may prove to be a useful by contribution to the cytotaxonomy of the genus. Specimens were collected near the "type" locality (Utinga, Belém, PA, Brazil. Chromosomal preparations from duodenal epithelial cells and testes were subjected to Giemsa staining, C-banding and DAPI/CMA3 fluorochrome staining. All specimens showed a karyotype with 13 bi-armed chromosome pairs (2n = 26. Nucleolar Organizer Regions, evidenced by CMA3, were located distally on the long arm of pair 7 (7q. DAPI+ heterochromatin was predominantly centromeric, with some small pericentromeric bands. Although the C-banding patterns of other Bolitoglossa species are so far unknown, cytogenetic studies conducted in other Plethodontid salamanders have demonstrated that pericentromeric heterochromatin is a useful cytological marker for identifying interspecific homeologies. Species diversification is usually accompanied by chromosomal changes. Therefore, the cytogenetic characterization of Bolitoglossa populations from the middle and western Brazilian Amazon Basin could identify differences which may lead to the identification of new species.

Full Text Available The aim of this study is to analyze the efficiency of Brazilian football clubs in generating revenues and the reasons behind it. To achieve this goal, we applied quantitative methods including Data Envelopment Analysis and Tobit regression modeling to data on the best clubs from 2012 to 2014, according to the Brazilian Football Confederation ranking. The results allowed for the inference that the largest Brazilian clubs, such as Grêmio (RS, Palmeiras (SP and Vasco (RJ, were not efficient in any period under analysis. Others, such as Guarani (SP and Guaratinguetá (SP, were efficient in all of years under consideration. With the Tobit regression model, we were able to determine that winning titles and the elite status of a given club are decisive factors in achieving efficiency. Included among the strategies that allow for greater efficiency in Brazilian clubs are the better utilization of stadiums and club assets, maximization of the financial worth of player popularity, and joining these with titles and a place in the A Series. Finally, the results of this study contribute to the strategic development of the football business, highlighting the positive effects that efficiency yields for clubs, thus supporting the growing body of research on sports management in Brazilian academia.

Full Text Available Understanding the dissipation of innovations is necessary to develop them, as a company on its own does not have all the capabilities that it needs. On the contrary, they are increasingly spread over internal and external contexts, and are not developed in isolation. Most of the time, they depend on interactive, innovative processes in a global context. The aim of this study is to evaluate how the global organizational structure of innovation affects the dynamic capability of cooperation (cooperability in Brazilian multinationals (BMNs. To achieve this goal, we conducted a survey of BMNs, and a final sample of 60 companies answered a structured questionnaire. We performed statistical tests such as Factor Analysis, Cronbach's Alpha, Multiple Regression and Hierarchical Cluster, and cross-analysis of quantitative results that enabled us to create a Cooperability Model, that is, a model of local, international and global development for a dynamic capability of cooperation in BMNs. The results show that technological strengths of foreign subsidiaries and the reverse transfer of their capabilities to the parent company and technology partners affect the dynamics of cooperation in BMNs (inputs and results of cooperability. Furthermore, we detected an inverse relationship between the autonomy of foreign subsidiaries and the dynamic of cooperation in BMNs.

This study evaluated the indoor air quality in Brazilian universities by comparing thirty air-conditioned (AC) (n = 15) and naturally ventilated (NV) (n = 15) classrooms. The parameters of interest were indoor carbon dioxide (CO2), temperature, relative humidity (RH), wind speed, viable mold, and airborne dust levels. The NV rooms had larger concentration of mold than the AC rooms (1001.30 ± 125.16 and 367.00 ± 88.13 cfu/m3, respectively). The average indoor airborne dust concentration exceeded the Brazilian standards (indoor air quality in Brazilian university classrooms affects the health of students. Therefore, indoor air pollution needs to be considered as an important public health problem.

Animal production is a leading economic activity in Brazil and antibiotics are widely used. However, the occurrence, behavior, and impacts of antibiotics in Brazilian soils are still poorly known. We evaluated the sorption behavior of four fluoroquinolones (norfloxacin, ciprofloxacin, danofloxacin, and enrofloxacin) and five sulfonamides (sulfadiazine, sulfachloropyridazine, sulfamethoxazole, sulfadimidine, and sulfathiazole) in 13 Brazilian soils with contrasting physical, chemical, and mineralogical properties. Fluoroquinolone sorption was very high (Kd≥544 L kg(-1)) whereas sulfonamide sorption ranged from low to high (Kd=0.7-70.1 L kg(-1)), consistent with previous reports in the literature. Soil texture and cation exchange capacity were the soil attributes that most affected sorption. Cation exchange was the most important sorption mechanism for the fluoroquinolones in highly weathered tropical soils, although cation bridging and ion pairing could not be ruled out. Hydrophobic partition played an important role in the sorption of the sulfonamides, but sorption was also affected by non-hydrophobic interactions with organic and/or mineral surfaces. Sorption for both compound classes tended to be higher in soils with high Al and Fe oxihydroxide contents, but they were not correlated with Kd values. No direct effect of soil pH was seen. The fluoroquinolones are not expected to leach even in worst-case scenarios (soils rich in sand and poor in organic carbon), whereas soil attributes dictate leaching potential for the sulfonamides.

Brazilian society declares no intention to development a nuclear artifact. This is on its Constitution. The submarine of nuclear propulsion may be used as a weapon of defense and, therefore, has a peaceful objective. Nationalism must be applied only to benefit the society. Nationalist attention has always been devoted, at various occasions, to the Brazilian nuclear sector. However, since Brazilian society has many needs and the Brazilian government always had numerous energy options, this sector has not been developed as it could be. Other successful applications of nuclear technology, besides electric generation, are not considered here. At present, the country is experiencing a moment of harassment of liberal forces. It is difficult to know if the population understands what is going on, due to the traditional media control. This media belongs to the capital. The rise and the fall of the nationalist strand in a country follow a global tendency and also depend of actions of the international capital. In nationalist periods, more decisions with positive social impact are taken. Therefore, sovereignty is necessary to increase the benefits to society. Unfortunately, the Brazilians deceived by the companies of mass communication and corrupt political leaderships allow the country to be dominated. Even the armed forces had their projects paralyzed. The nuclear sector, as all other, suffers with the low budget and the future is difficult to predict. (author)

Heloiza G. Herckovitz

2011-02-01

Full Text Available A content analysis of four Brazilian news media portals found that economic news dominated the top headlines with little attention paid to education, the environment and welfare. Other trends included a focus on local events and national news sources, reliance on few sources, mostly official ones, and a low percentage of news that fitted the concept of newsworthiness (a combination of both social significance and deviance concepts. Other findings of a study of 432 top news stories published by UOL, Estadão, iG and Terra during a 15-day period between February and March 2008 indicate that the top portions of the portals’ front pages carry news that lacks story depth, editorial branding, and multimedia applications. The results suggest that online news portals are in their infancy although Brazil has the largest online population of Latin America. This study hopes to shed light on the gatekeeping process in Brazilian news portals. Brazilian media portals have yet to become a significant editorial force able to provide knowledge about social issues and public affairs in a socially responsible fashione.

The analysis of patent activity is one methodology used for technological monitoring. In this paper, the activity of biotechnology-related patents in Brazil were analyzed through 30 International Patent Classification (IPC) codes published by the Organization for Economic Cooperation and Development (OECD). We developed a program to analyse the dynamics of the major patent applicants, countries and IPC codes extracted from the Brazilian Patent Office (INPI) database. We also identified Brazilian patent applicants who tried to expand protection abroad via the Patent Cooperation Treaty (PCT). We had access to all patents published online at the INPI from 1975 to July 2010, including 9,791 biotechnology patent applications in Brazil, and 163 PCTs published online at World Intellectual Property Organization (WIPO) from 1997 to December 2010. To our knowledge, there are no other online reports of biotechnology patents previous to the years analyzed here. Most of the biotechnology patents filed in the INPI (10.9%) concerned measuring or testing processes involving nucleic acids. The second and third places belonged to patents involving agro-technologies (recombinant DNA technology for plant cells and new flowering plants, i.e. angiosperms, or processes for obtaining them, and reproduction of flowering plants by tissue culture techniques). The majority of patents (87.2%) were filed by nonresidents, with USA being responsible for 51.7% of all biotechnology patents deposited in Brazil. Analyzing the resident applicants per region, we found a hub in the southeast region of Brazil. Among the resident applicants for biotechnology patents filed in the INPI, 43.5% were from São Paulo, 18.3% were from Rio de Janeiro, and 9.7% were from Minas Gerais. Pfizer, Novartis, and Sanofi were the largest applicants in Brazil, with 339, 288, and 245 biotechnology patents filed, respectively. For residents, the largest applicant was the governmental institution FIOCRUZ (Oswaldo Cruz

Full Text Available Reflecting on the importance of multiculturalism in teaching process and observing the otherness are primarily a challenge. This enables us to rethink what we have within ourselves, also to reconstitute memories involving discriminatory and unethical attitudes, which takes place in social fellowship. Based on the studies of Walsh (2007, 2009, Gomes (2007 and Tavares (2011, this work relies on decoloniality studies, mainly on the relevance of the history of Africa and Africanness in Brazilian education. Our corpus of analysis is found in the "Diretrizes Curriculares Nacionais para a Educação Básica" (DCN, 2013, the Brazilian Legislative Syllabus for Basic Education. Our focus is on the chapters concerning the Native-Brazilian and Quilomboa Education and ethnic-racial relations. Our most important aims are: to show the intercultural theoretical framework in which they are based on; to understand the immediate link established between the Native-Brazilian education and intercultural perspective; to clarify how the African diaspora was carried out in this particular case. Based on some Excel resources we were able to: 1 stablish the predominance of functional framework of interculturalism throughout these chapters, along with some critical features of interculturalism, as the issue of curricular decoloniality; 2 observe the established relationship between bilingualism and multiculturalism in the guidelines of Native-Brazilian education; and 3 identify a search for an effective inclusion of Africanness in curricula supported by the historical recognition and visibility of their sociocultural contribution.

distributions similar to those of the Brazilian population, as defined by the Brazilian Institute of Geography and Statistics (IBGE. RESULTS: Eighty-seven percent of respondents were in favor of organ donation. There was no difference in the percentage of respondents in favor of donation in relation to gender, marital status, religion, and income. The main reasons in favor of donation were to save life, to help other persons and to donate life. The main reasons against donation were distrust towards medicine or the Brazilian transplantation organization, the existence of organ sale, and fear of body mutilation. Most respondents believed that wealthy people have a better chance to receive an organ than poor people, that sales of organs exists in Brazil, and that misdiagnosis of brain death may occur. CONCLUSION: Most respondents are in favor of organ donation and have a good knowledge of organ donation and transplantation. The majority distrusts Brazilian organization of organ distribution and brain death diagnosis.

Angel Cobo

2012-08-01

Full Text Available Different theories of organization and management are based on implicit images or metaphors. Nevertheless, a quantitative approach is needed to minimize human subjectivity or bias on metaphors studies. Hence, this paper analyzed the presence of metaphors and clustered them using fuzzy data mining techniques in a sample of 61 Brazilian companies that operate in the state of Rio Grande do Sul. For this purpose the results of a questionnaire answered by 198 employees of companies in the sample were analyzed by R free software. The results show that it is difficult to find a clear image in most organizations. In most cases characteristics of different images or metaphors are observed, so soft computing techniques are particularly appropriate for this type of analysis. However, according to these results, it is noted that the most present image in the organizations studied is that of “organisms” and the least present image is that of a “political system” and of an “instrument of domination”

2011-01-01

Ethanol has recently been of great interest worldwide because it is a viable economic alternative to petroleum products and it is a renewable source of energy that mitigates the emission of greenhouse gases. Brazilian bioethanol from sugarcane is the most successful case at the world level because of its low cost and low level of greenhouse gas emissions. Brazil's success with sugarcane cannot be understood as based solely on a natural comparative advantage, but as a result of efforts that culminated in a positive trajectory of technological learning, relying mostly on incremental innovations. The purpose of this article is to analyze the key aspects of the innovation system built around the Brazilian sugarcane industry. It is based on the national innovation systems approach according to which innovation results from the interaction of different institutional actors. Institutional arrangements are analyzed as the basis for the innovative process, in particular R and D and the innovation policies and strategies of the main players in the sugarcane sector, including sugar and ethanol mills, industrial goods suppliers, public and private research institutions, and governmental agencies. - Research Highlights: → The Brazilian success in bioethanol is due to the sugarcane innovation system. → Private funds for R and D became central after IAA closure. → Nowadays Brazilian innovation system is transforming to keep its leadership. → Public funds for research in the second generation bioethanol.

Full Text Available This study aims to identify characteristics of national culture in the culture of Brazilian school management and leadership. Considering the broad literature that deals with the peculiarities of Brazilian culture and its influence on Brazilian management, it is assumed that as an institution belonging to a particular society, the school offers internal dynamics that are organized under influences of historical and cultural determinants of this society. This work is an exploratory study that uses secondary data found in studies on the profiles of principals, leadership, climate, and organizational culture in schools and primary data from research applied in public secondary schools located in the Federal District, Brazil. The results demonstrate that the initial premise—national culture influences the organizational culture and school leadership—has been confirmed and aspects that merit further analysis are identified.

The Brazilian Amazon frontier shows how remarkable leadership can work towards increased agricultural productivity and environmental sustainability without new greenhouse gas emissions. This is due to initiatives among various stakeholders, including national and state government and agents, farmers, consumers, funding agencies and non-governmental organizations. Change has come both from bottom-up and top-down actions of these stakeholders, providing leadership, financing and monitoring to foster environmental sustainability and agricultural growth. Goals to reduce greenhouse gas emissions from land-cover and land-use change in Brazil are being achieved through a multi-tiered approach that includes policies to reduce deforestation and initiatives for forest restoration, as well as increased and diversified agricultural production, intensified ranching and innovations in agricultural management. Here, we address opportunities for the Brazilian Amazon in working towards low-carbon rural development and environmentally sustainable landscapes.

Possible trends of sense production based on reading are looked for in the set of narratives, considering that, in the organization of their components, such texts carry a potential of meanings which are updated at each reading. Since the narratives cover recent historical events, it is concluded that social memory and history play a peculiar role as mechanisms external to narrative that reflect their internal mechanisms and possibilities of history meaning. In this analysis, elements of language studies and theory of history, with regard to its teaching, are broadly present. How to reference this article Rocha, H. (2015.

This paper presents an economic assessment of Brazilian agribusiness and its relationship with other economic sectors. It was found that, in 2011, agribusiness had a share of 18.45% (basic prices) and 19.77% (market prices) of Brazilian GDP. The tax burden of agribusiness (20.68%) was higher than that of other sectors (13.59%), despite agribusiness being a major contributor to the generation of foreign exchange, employment, and essential products, such as food. Brazilian agribusiness is a major employer, responsible for 29.39% of national employment. However, its average income is lower than in the other sectors of the Brazilian economy. Finally, agribusiness was found to be the biggest generator of foreign exchange, with a positive balance of trade. It was possible to conclude that agribusiness forms a strong link between agriculture and livestock, industry, and services in other economic sectors. For this reason, it can be said that the development of agribusiness is highly relevant to the process of Brazilian economic development and is therefore important to the progress of economic policies.

The purpose of this study was to assess the characteristics and prevalence of sports-related injuries in visually disabled athletes of the Brazilian football 5-a-side team. The participants were 13 male athletes, all classified as B1 visual class, members of the Brazilian team, who played in five consecutive international competitions. Data were collected using the Brazilian Paralympic Committee and the Brazilian Confederation of Sports for the Blind report form. From the total of 13 athletes, 11 succumbed to some form of injury during the 5 competitions, which incorporated 23 matches, representing a prevalence of 84.6%. A total of 35 sports injuries were recorded, giving a clinical incidence of 2.7 injuries per athlete and an injury risk of 0.85 and an incidence rate of 0.12 injuries per match. Traumatic injuries (80%) were more common than overuse injuries (20%) (psports-related injuries in 5-a-side football in blind athletes. The results are important in guiding strategies to inform the implementation of preventive pathways and provide a strong rationale for the compulsory use of additional protective equipment. © Georg Thieme Verlag KG Stuttgart · New York.

The Brazilian business and growth cycles

Directory of Open Access Journals (Sweden)

Chauvet Marcelle

2002-01-01

Full Text Available This paper uses several produceres to date and analyse the Brazilian business and growth cycles. In particular, a Markov switching model is fitted to quarterly and annual real production data. The smoothed probabilities of the Markov states are used as predictive rules to define different phases of cyclical fluctuations of real Brazilian production. The results are compared with different non-parametric rules. All methods implemented yield similar dating and reveal asymmetries across the different states of the Brazilian business and growth cycles, in which slowdowns and recessions are short and abrupt, while high growth phases and expansions are longer and less steep. The resulting dating of the Brazilian economic cycles can be used as a reference point for construction and evaluation of the predictive performance of coincident, leading, or lagging indicators of economic activity. In addition, the filtered probabilities obtained from the Markov switching model allow early recognition of the transition to a new business cycle phase, wich can be used, for example, for evaluation of the adequate strength and timing of countercyclical policies, for reassessment of projected sales or profits by businesses and investors, or for monitoring of inflation pressures.

RMB. The new Brazilian multipurpose research reactor

Brazil has four research reactors (RR) in operation: IEA-R1, a 5 MW pool type RR; IPR-R1, a 100 kW TRIGA type RR; ARGONAUTA, a 500 W Argonaut type RR, and IPEN/MB-01, a 100 W critical facility. The first three were constructed in the 50's and 60's, for teaching, training, and nuclear research, and for many years they were the basic infrastructure for the Brazilian nuclear developing program. The last, IPEN/MB-01, is the result of a national project developed specifically for qualification of reactor physics codes. Considering the relative low power of Brazilian research reactors, with exception of IEAR1, none of the other reactors are feasible for radioisotope production, and even IEA-R1 has a limited capacity. As a consequence, since long ago, 100% of the Mo-99 needed to attend Brazilian nuclear medicine services has been imported. Because of the high dependence on external supply, the international Moly-99 supply crisis that occurred in 2008/2009 affected significantly Brazilian nuclear medicine services, and as presented in previous IAEA events, in 2010 Brazilian government formalized the decision to build a new research reactor. The new reactor named RMB (Brazilian Multipurpose Reactor) will be a 30 MW open pool type reactor, using low enriched uranium fuel. The facility will be part of a new nuclear research centre, to be built about 100 kilometres from Sao Paulo city, in the southern part of Brazil. The new nuclear research centre will have several facilities, to use thermal and cold neutron beams; to produce radioisotopes; to perform neutron activation analysis; and to perform irradiations tests of materials and fuels of interest for the Brazilian nuclear program. An additional facility will be used to store, for at least 100 years, all the fuel used in the reactor.

Vermiculites are clay minerals similar to montmorillonites differing for crystalline structures. The product exfoliated is odorless, hydrophobic, not irritate the skin and not the lungs. These properties provide the modified thermally vermiculite a product of broad application in the sectors of construction, agriculture and industry. The aim this work is the comparative analysis between two vermiculites micron fractions from different localities of the northeastern Brazilian region, UBM/PB and EUCATEX/PI. Samples exfoliated to 950 deg C were leached for removal of organic matter by oxidation with hydrogen peroxide. The spectroscopy in the infrared, FTIR and X-ray diffraction, XRD, were used to characterize the samples. Data from X-ray diffraction showed that the structural characteristics of the mineral samples were not significantly altered with the process of leaching and the IR spectra proved the efficiency of procedure for removal of organic impurities (author)

Implementation of the Brazilian national repository

International Nuclear Information System (INIS)

Tello, Cledola Cassia Oliveira de

2013-01-01

Ionizing radiation in Brazil is used in electricity generation, medicine, industry, agriculture and for research and development purposes. All these activities can generate radioactive waste. At this point, in Brazil, the use of nuclear energy and radioisotopes justifies the construction of a national repository for radioactive wastes of low and intermediate-level. According to Federal Law No. 10308, Brazilian National Commission for Nuclear Energy (CNEN) is responsible for designing and constructing the intermediate and final storages for radioactive wastes. Additionally, a restriction on the construction of Angra 3 is that the repository is under construction until its operation start, attaining some requirements of the Brazilian Environmental Regulator (IBAMA). The RBMN Project (Repository for Low and Intermediate-Level Radioactive Wastes) aims at the implantation of a National Repository for disposal of low and intermediate-level of radiation wastes. This Project has some aspects that are unique in the Brazilian context, especially referring to the time between its construction and the end of its institutional period. This time is about 360 years, when the area will be released for unrestricted uses. It means that the Repository must be safe and secure for more than three hundred years, which is longer than half of the whole of Brazilian history. This aspect is very new for the Brazilian people, bringing a new dimension to public acceptance. Another point is this will be the first repository in South America, bringing a real challenge for the continent. The current status of the Project is summarized. (author)

The present paper aimed to identify the stakeholders, as well as their arguments and recommendations, in the debate on the application of a food processing-based classification system to the new Brazilian Food Guide. Qualitative approach; an analysis was made of documents resulting from the consultation conducted for the development of the new Brazilian Food Guide, which uses the NOVA classification for its dietary recommendations. A thematic matrix was constructed and the resulting themes represented the main points for discussion raised during the consultation. Brazil. Actors from academia, government and associations/unions/professional bodies/organizations related to the area of nutrition and food security; non-profit institutions linked to consumer interests and civil society organizations; organizations, associations and food unions linked to the food industry; and individuals. Four themes were identified: (i) conflicting paradigms; (ii) different perceptions about the role and need of individuals; (iii) we want more from the new food guide; and (iv) a sustainable guide. There was extensive participation from different sectors of society. The debate generated by the consultation revealed two main conflicting opinions: a view aligned with the interests of the food industry and a view of healthy eating which serves the interests of the population. The first group was against the adoption of a food processing-based classification system in a public policy such as the new Brazilian Food Guide. The second group, although mostly agreeing with the new food guide, argued that it failed to address some important issues related to the food and nutrition agenda in Brazil.

Low back pain (LBP) is little explored in the aging population especially when considering age-relevant and culturally dependent outcomes. We aimed to describe socio-demographic and clinical characteristics of Brazilian older people with a new episode of LBP presenting to primary care. We sourced baseline information on socio-demographic, pain-related and clinical characteristics from 602 older adults from the Brazilian Back Complaints in the Elders (Brazilian BACE) study. We analyzed differences in pain, disability, functional capacity and psychosocial factors between sub-groups based on age (i.e. participants aged 55-74 or ≥75 years), education (i.e. those with four years or less of schooling or those with more than four years of schooling) and income (i.e. participants who reported earning two or less minimal wages or three and more). Participants presented severe LBP (7.18/10, SD: 2.59). Younger participants were slightly more disabled (mean difference 1.29 points, 95% confidence interval [CI]: 0.03/5.56), reporting poorer physical health, and less fall-related self-efficacy (mean difference of 2.41, 95% CI 0.35/4.46). Those less educated, and those with income equal or less than two minimum wages had more disability, pain catastrophizing and worse functional capacity. This was the first study showing that Brazilian older adults with LBP present high levels of functional disability and psychological distress, especially those with low socioeconomic status.

2014-01-01

Full Text Available The concern about health and environmental aspects are increasingly present in our society. In 1976 José Lutzemberger publishes the first Brazilian ecological manifesto. In 2003 the Law 10.831 is approved, which conceptualizes and defines organic agriculture. In 1982, the first Biodynamic Agriculture meeting in Brazil happens, where the construction of the basis for the implementation of biodynamic in Brazilian agriculture started. In 1995 the Brazilian Association of Biodynamic Agriculture is created. The search for organic products – that doesn't use artificial mineral and chemical fertilizers and exploits fertility as a way of fighting diseases and pests – and biodynamic products in the agricultural production unit is understood as a kind of organism also take place in the wine industry. But knowing which producers are involved in this type of activity is still a difficult task for the community, especially due to the informality of some agents. Thus, this paper proposes to identify organic and biodynamic wine producers in southern Brazil; as well as the tools and policies which have encouraged farmers to adopt these practices. Finally, understanding the main obstacles producers find dealing with certifications mechanisms. This region was chosen for being the largest grape and wine producing in the country.

Even considered not essential for plants, cesium may cycle within forest ecosystems. Taking into account the lack of knowledge on the distribution of this chemical element in Brazilian ecosystems, this work encompasses the unexpected cesium accumulation in native plant leaves from Cerradao, a Brazilian hotspot of world biodiversity. Some trees were Cs accumulators, achieving mass fractions in leaves 700 times higher (up to 12.7 mg kg -1 ) when compared to other Brazilian native tree leaves from the Atlantic Forest. In fact, such trace element accumulation in leaves was not previously noticed for Brazilian ecosystems despite the intra- and inter-species variability observed in Cerrado tree leaves. (author)

Linei Augusta Brolini Dellê Urban

Full Text Available Abstract Objective: To present the current recommendations for breast cancer screening in Brazil, as devised by the Brazilian College of Radiology and Diagnostic Imaging, the Brazilian Breast Disease Society, and the Brazilian Federation of Gynecological and Obstetrical Associations. Materials and methods: We analyzed scientific studies available in the Medline and Lilacs databases. In the absence of evidence, the recommendations reflected the consensus of a panel of experts. Recommendations: Annual mammography screening is recommended for women 40-74 years of age. Among women ≥ 75 years of age, annual mammography screening should be reserved for those with an expected survival > 7 years. Complementary ultrasound should be considered for women with dense breasts. Complementary magnetic resonance imaging is recommended for women at high risk. When available, an advanced form of mammography known as tomosynthesis can be considered as a means of screening for breast cancer.

In the Brazilian Cerrado, despite the increasing adoption of no-till systems, there are still extended areas under conventional soil management systems that reduce soil carbon (C) and nitrogen (N) stocks and increase the emissions of greenhouse gases, such as nitrous oxide (N 2 O). Conservation agroecosystems, such as no-till, have been proposed as a strategy to mitigate agriculture-induced climatic changes through reductions in N 2 O emissions. However, the relationship between organic matter and N 2 O emissions from soils under different agroecosystems is not yet clear. This study hypothesized that agroecosystems under no-till promote an accumulation of labile and stable SOM fractions along with a reduction of N 2 O emissions. This study evaluated the effects of crop-rotation agroecosystems: i) on C and N pools and labile and stable SOM fractions; ii) on cumulative N 2 O emissions; and iii) on the relationships between SOM fractions and N 2 O emissions. The agricultural systems consisted of: (I) soybean followed by sorghum under no-tillage (NT1); (II) maize followed by pigeon pea under no-tillage (NT2); (III) soybean under conventional tillage followed by fallow soil (CT); (IV) and native Cerrado (CER). After CT for 18years, following the replacement of CER, the soil C stock in the 0-20cm layer was reduced by 0.64tha -1 year -1 . The no-till systems were more efficient in accumulating labile and stable C fractions with values close to those observed under CER, and were directly related to lower soil N 2 O emissions. The cumulative pattern of N 2 O emissions was inverse to that of the following SOM fractions: microbial biomass carbon, permanganate-oxidizable carbon, particulate organic carbon, inert carbon, and humic substances. Based on principal component analysis, the CT was generally separated from the other land use systems. This separation was strongly influenced by the low C contents in the different SOM fractions and higher N 2 O emissions promoted by the

This is a systematic review based on the integrative review method, which sought to analyze the characteristics of knowledge produced by studies on crack, in Brazilian Master's and Doctoral courses. The investigation comprised 33 studies (18 dissertations and 15 theses). Among them, 51.5% were from the Health Science area with emphasis on the Postgraduate Program in Psychiatry (and Medical Psychology), which provided five dissertations/theses. Most of the knowledge on the epidemic (51.5%) are from the Universidade Federal de São Paulo and Universidade de São Paulo, with the largest number of studies (81.8%) concentrated in the southeast. The themes most analyzed were: organic alterations, drug trafficking and crack use, HIV/Aids, types and strategies of treatment. The results showed that Brazilian stricto sensu knowledge about crack is still incipient, sketchy and ineffectual, albeit promising due to demands and implications that this epidemic imposes upon society.

Transcultural Diabetes Nutrition Algorithm: Brazilian Application

Directory of Open Access Journals (Sweden)

Fabio Moura

2015-09-01

Full Text Available The prevalence of obesity, pre-diabetes, and type 2 diabetes (T2D is increasing worldwide, especially in the developing nations of South America. Brazil has experienced an exponential increase in the prevalence of these chronic non-communicable diseases. The rising prevalence is probably due to changing eating patterns, sedentary living, and a progressive aging of the population. These trends and their underlying causes carry untoward consequences for all Brazilians and the future of Brazilian public health and the healthcare system. Lifestyle changes that include healthy eating (nutrition therapy and regular physical activity (structured exercise represent efficient inexpensive measures to prevent and/or treat the aforementioned disorders and are recommended for all afflicted patients. Regrettably, the implementation of lifestyle changes is fraught with clinical and personal challenges in real life. The transcultural Diabetes Nutrition Algorithm (tDNA is a therapeutic tool intended to foster implementation of lifestyle recommendations and to improve disease-related outcomes in common clinical settings. It is evidence-based and amenable to cultural adaptation. The Brazilian Diabetes Association, Society of Cardiology and Ministry of Health guidelines for nutrition therapy and physical exercise were considered for the Brazilian adaptation. The resultant tDNA-Brazil and its underlying recommendations are presented and explained.

Earning management in Brazilian financial institutions

2016-06-01

Full Text Available ABSTRACT The present study aims to study earnings management in a significant sample of 123 banks in the Brazilian market between 2001 and 2012. Given the important role that banks play in a country's economy, it is important to understand that there are discretionary factors involved in the reporting of a financial institution's profitability. Credit provisioning guidelines for Brazilian financial institutions are described in Resolution 2682/99 of the National Monetary Council (Conselho Monetário Nacional. Because of the discretion allowed in this resolution, loan loss provision is used as instrument of earnings management, which is not an illegal practice, but this behavior does affect the risk perception of agents and analysts, and they should be aware of it and understand it. We found that credit provisioning is used as an earnings management mechanism to smooth the net income of Brazilian financial institutions. Brazilian banks tend to avoid not only negative net income pre-loan loss provisions and taxes, but also negative net income pre-loan loss provisions and taxes in relation to the previous period. Contrary to the previous studies, it is not clear if banks avoid lower net income pre-loan loss provisions and taxes than a given peer group.

Periodic assessment is one of the recommendations for improving health-care waste management worldwide. This study aimed at translating and adapting the Health-Care Waste Management - Rapid Assessment Tool (HCWM-RAT), proposed by the World Health Organization, to a Brazilian Portuguese version, and resolving its cultural and legal issues. The work focused on the evaluation of the concepts, items and semantic equivalence between the original tool and the Brazilian Portuguese version. A cross-cultural adaptation methodology was used, including: initial translation to Brazilian Portuguese; back translation to English; syntheses of these translation versions; formation of an expert committee to achieve consensus about the preliminary version; and evaluation of the target audience's comprehension. Both the translated and the original versions' concepts, items and semantic equivalence are presented. The constructs in the original instrument were considered relevant and applicable to the Brazilian context. The Brazilian version of the tool has the potential to generate indicators, develop official database, feedback and subsidize political decisions at many geographical and organizational levels strengthening the Monitoring and evaluation (M&E) mechanism. Moreover, the cross-cultural translation expands the usefulness of the instrument to Portuguese-speaking countries in developing regions. The translated and original versions presented concept, item and semantic equivalence and can be applied to Brazil.

Loss of [ 14 C] parathion from two Brazilian soils was studied by measuring the parathion which could be extracted by a mixture of hexane and propanol and the 14 CO 2 evolved. Recovery of unchanged parathion decreased faster in the soil richer in organic matter (soil 1) from which more radiocarbon was evolved as CO 2 than from the soil poorerin organic matter (soil 2). Evolution of CO 2 from soil 1 decreased rapidly when the soil dried out but little effect of moisture content was observed in soil 2. Radiocarbon remaining in the soils was assayed by combustion after 234 days and the total recovered in soil 1 was 95.6% and, in soil 2,78.7%, sufficient to give almost complete recovery from both soils.

The objectives of the study were to analyze the attitude of medical and nursing personnel toward deceased organ donation in two hospitals in Rio de Janeiro, Brazil, and the factors that can affect this attitude. A random sample (n = 162) was selected from the population of nurses and physicians in the hospitals analyzed. The sample was stratified by age, sex, marital status, religion, professional category, and educational level. A validated questionnaire addressing psychosocial aspects of organ donation was used to evaluate attitudes. The χ 2 and Mann-Whitney U tests were applied for statistical analysis. Of personnel surveyed, 86.4% (n = 140) were in favor of deceased organ donation, whereas 11.1% (n = 18) were not sure and 2.5% (n = 4) were against. The favorable attitude was related to the following aspects: (1) educational level, (2) having spoken with family members about organ donation, (3) having a chronic disease, (4) favorable attitude of one's family, (5) belief that organ donation can save lives, (6) concerns about body manipulation, illegal trade of organs, and organ donation being against God's will, (7) feeling proud of working with organ donation/transplantation, (8) self-assessment of experience and knowledge in organ donation/transplantation activities (P organ donation is well accepted among the healthcare professionals surveyed, and the attitude is affected by socio-personal variables.

Full Text Available In 1912 the Brazilian diplomat and scholar Manuel de Oliveira Lima gave six lectures at Stanford University that encapsulated his views of what we now call Brazilian Studies. This article summarizes Oliveira Lima’s lectures. It then points out three aspects of Oliveira Lima’s worldview that are problematic from the perspective of the twenty-first century: his Eurocentrism; the unproblematic nature of the nation-state in his thinking; and his largely negative view of Brazil’s racial heritage. The third part of the essay analyzes three aspects of Oliveira Lima’s lectures that are still contemporary. These are the need to establish an adequate comparative context for the study of Brazil; the difficulty of justifying an academic discipline that revolves around the study of a single country; and the challenge of uniting disparate and specialized disciplines in order to appreciate Brazil’s complexity and trajectory in the modern world. In the conclusion, some guidelines for maintaining Brazilian Studies as a vibrant field are suggested.

2000-01-01

It is recognized the economic benefits that might follow the opening process of the Brazilian oil and natural gas industry, which shall experience a fast expansion with the arrival of national and international private investors. However, we should not neglect the broader impact of this process on the future development of all that cluster of national agents that lived around and served the former national oil monopoly, managed by the Brazilian National Oil Company, Petrobras. This work focuses on this larger perspective, discussing about the capacity of Brazil to sustain and expand its competitiveness in the oil business as well as to obtain the maximum economic development from the exploration of its oil and gas reserves. We adopt the work of Michael Porter, from the University of Harvard, about the Competitive Advantage of Nations, as a theoretical model to analyze the Competitive Advantage of Brazil in the global oil industry. By introducing the concept of ''oil diamond'', adapted from the notion introduced by this author, we develop a new understanding of national competitiveness in the oil sector. In this paper, we present the general model as well as a brief characterization of the results found for Brazil Subsequently, we focus on just one leg of the model, for which we discuss, with more detail, about the competitive condition of the country in the opening-up scenario. This leg regards the so-called supporting and supplementary industries that constitute what is denominated in the French tradition the ''para petroleum'' industry. We analyze the conditions for the Brazilian domestic ''para petroleum industry'' to survive and grow in the new competitive environment. (authors)

The overall goal of NASA's SCAR (Smoke, Cloud and Radiation) Program is to obtain physical and chemical properties of the smoke produced by biomass burning and the effects of the smoke on the earth's radiation balance and climate. It is a joint project with the Brazilian government and their organizations, including INPE (Instituto Nacional Pesquisas Espaciais) who actively participate in all activities. Appropriate estimates of the biomass buming in the tropics is therefore essential to determine its effect on the atmosphere and on climate. The SCAR series of experiments is designed with that purpose. The present study of evaluating the burnt-out areas is to augment the data collected to date to help evaluate the effect of biomass burning.

Full Text Available The situation of Brazilian Science and Technology Parks (STPs operation led to the field research. Even with the public policy of stimulus and support of associations, nothing has been mapped on the dissemination of results (economic growth and regional development. This scenario instigates the question: What are the governance characteristics of Brazilian Science and Technology Parks? A empirical field research was developed, taking into consideration the possibility of replication trought the registration of the choice criteria in the multiple cases and trought research detalhes and data colection. Eight STPs (TECNOPUC - Porto Alegre, Valetec - Novo Hamburgo, Tecnosinos - Sao Leopoldo, Unicamp, CIATEC and TECHNOPARK - Campinas, Rio Park - Rio de Janeiro and SergipeTec participated in research. The results and considerations about the research question allows to infer the little effectiveness of governance (without qualitative or quantitative performance indicators is possibly caused by tensions characterized by elements such as heterogeneity in characteristics of organizations that are part of STPs, lack of consensus on common goals, pressure forces and influences affecting trusts, nonconformity standards and personal and organizational preferences. Leadership relations championed by the government and / or companies can negatively influence the STP's performance as a whole.

The Corporate Governance of Privately Controlled Brazilian Firms

Érica C. R. Gorga

2009-09-01

Full Text Available We provide an overview of the corporate governance practices of Brazilian public companies, based primarily on an extensive 2005 survey of 116 companies. We focus on the 88 responding Brazilian private firms which are not majority owned by the state or a foreign company. We identify areas where Brazilian corporate governance is relatively strong and weak. Board independence is an area of weakness: The boards of most Brazilian private firms are comprised entirely or almost entirely of insiders or representatives of the controlling family or group. Many firms have zero independent directors. At the same time, minority shareholders have legal rights to representation on the boards of many firms, and this representation is reasonably common. Financial disclosure lags behind world standards. Only a minority of firms provide a statement of cash flows or consolidated financial statements. However, many provide English language financial statements, and an English language version of their website. Audit committees are uncommon, but many Brazilian firms use an alternate approach to ensuring financial statement accuracy – establishing a fiscal board. A minority of firms provide takeout rights to minority shareholders on a sale of control. Controlling shareholders often use shareholders agreements to ensure control.

The air transportation network in a country has a great impact on the local, national and global economy. In this paper, we analyze the air transportation network in Brazil with complex network features to better understand its characteristics. In our analysis, we built networks composed either by national or by international flights. We also consider the network when both types of flights are put together. Interesting conclusions emerge from our analysis. For instance, Viracopos Airport (Campinas City) is the most central and connected airport on the national flights network. Any operational problem in this airport separates the Brazilian national network into six distinct subnetworks. Moreover, the Brazilian air transportation network exhibits small world characteristics and national connections network follows a power law distribution. Therefore, our analysis sheds light on the current Brazilian air transportation infrastructure, bringing a novel understanding that may help face the recent fast growth in the usage of the Brazilian transport network.

Full text: Since the term“knowledge management”was coined, it has gained more and more attention in an effort to re-structure organizations. A good deal of effort has been done in order to better implement a knowledge management culture in organizations throughout all the work sectors. The Brazilian Federal Government through the Decree no.5.707, dated February 23, 2006, democratically created a national policy for human development. This initiative made equally available additional education opportunities for all staff in order to form a competent workforce which included official recognition of work-related skills. In the field of nuclear energy, the National Nuclear Energy Commission is a Brazilian governmental authority which has long served as the leader in the matter. In this respect, and in the light of the International Atomic Energy Agency (IAEA) nuclear knowledge management role and the perspective of the first and third dimensions, the aim of this paper is to share the outcome of the Government programme in the National Nuclear Energy Commission.

The Brazilian Twin Registry (BTR) was established in 2013 and has impelled twin research in South America. The main aim of the initiative was to create a resource that would be accessible to the Brazilian scientific community as well as international researchers interested in the investigation of the contribution of genetic and environmental factors in the development of common diseases, phenotypes, and human behavior traits. The BTR is a joint effort between academic and governmental institutions from Brazil and Australia. The collaboration includes the Federal University of Minas Gerais (UFMG) in Brazil, the University of Sydney and University of Melbourne in Australia, the Australian Twin Registry, as well as the research foundations CNPq and CAPES in Brazil. The BTR is a member of the International Network of Twin Registries. Recruitment strategies used to register twins have been through participation in a longitudinal study investigating genetic and environmental factors for low back pain occurrence, and from a variety of sources including media campaigns and social networking. Currently, 291 twins are registered in the BTR, with data on demographics, zygosity, anthropometrics, and health history having been collected from 151 twins using a standardized self-reported questionnaire. Future BTR plans include the registration of thousands of Brazilian twins identified from different sources and collaborate nationally and internationally with other research groups interested on twin studies.

The southern Brazilian grassland biome: soil carbon stocks, fluxes of greenhouse gases and some options for mitigation.

Pillar, V D; Tornquist, C G; Bayer, C

2012-08-01

The southern Brazilian grassland biome contains highly diverse natural ecosystems that have been used for centuries for grazing livestock and that also provide other important environmental services. Here we outline the main factors controlling ecosystem processes, review and discuss the available data on soil carbon stocks and greenhouse gases emissions from soils, and suggest opportunities for mitigation of climatic change. The research on carbon and greenhouse gases emissions in these ecosystems is recent and the results are still fragmented. The available data indicate that the southern Brazilian natural grassland ecosystems under adequate management contain important stocks of organic carbon in the soil, and therefore their conservation is relevant for the mitigation of climate change. Furthermore, these ecosystems show a great and rapid loss of soil organic carbon when converted to crops based on conventional tillage practices. However, in the already converted areas there is potential to mitigate greenhouse gas emissions by using cropping systems based on no soil tillage and cover-crops, and the effect is mainly related to the potential of these crop systems to accumulate soil organic carbon in the soil at rates that surpass the increased soil nitrous oxide emissions. Further modelling with these results associated with geographic information systems could generate regional estimates of carbon balance.

Full Text Available This study evaluated the indoor air quality in Brazilian universities by comparing thirty air-conditioned (AC (n = 15 and naturally ventilated (NV (n = 15 classrooms. The parameters of interest were indoor carbon dioxide (CO2, temperature, relative humidity (RH, wind speed, viable mold, and airborne dust levels. The NV rooms had larger concentration of mold than the AC rooms (1001.30 ± 125.16 and 367.00 ± 88.13 cfu/m3, respectively. The average indoor airborne dust concentration exceeded the Brazilian standards (<80 µg/m3 in both NV and AC classrooms. The levels of CO2 in the AC rooms were significantly different from the NV rooms (1433.62 ± 252.80 and 520.12 ± 37.25 ppm, respectively. The indoor air quality in Brazilian university classrooms affects the health of students. Therefore, indoor air pollution needs to be considered as an important public health problem.

Full Text Available This paper aims at discussing some images constituted as erotic on Brazilian television. The Brazilian soap operas Gabriela (Rede Globo, 1975, and Pantanal (Rede Manchete, 1990, and their main characters, Gabriela and Juma, will be analyzed in detail. The Veja Magazine had a most influent part in constituting such “erotic” subjects through the divulging and commenting of positive, seductive attributes on the bodies of the eroticized actresses. Gabriela and Juma are important characters because they support the stereotypes of a Brazilian sensuality and the strong mundane aspects, such as sex-appeal and dark bodies. The text explores the Brazilian television production (soap operas in order to map the images which have contributed to build the subjectively Brazilian eroticism.

To characterize the performance of Brazilian students exposed to two languages in reading fluency, phonological memory, and rapid naming, according to grade level, and to investigate correlations between these variables. Sixty students took part in this study (50% female), enrolled in the third to the fifth grades of two elementary schools of the city of São Paulo. They constituted two groups - bilingual group: 30 Brazilian children whose mother tongue and language spoken at home was Brazilian Portuguese and who were daily exposed to English at school for a period not shorter than three years; monolingual group: 30 students, from a monolingual Brazilian elementary school, who were paired by gender, age, and grade level with the bilingual students. Foreign children, children with complaint or indication of speech and language disorder, or who had been retained were excluded. A rapid automatized naming, pseudoword repetition, and oral reading tests were administered. The bilingual children were assessed in both languages and their performances were compared among themselves and with the monolingual group, which was only assessed in Brazilian Portuguese. The bilingual group showed better performance in English, rapid naming, and pseudoword repetition tasks, whereas Brazilian Portuguese, in reading fluency. A higher number of correlations were found in Brazilian Portuguese. The results suggest that the acquisition of a second language may positively influence the abilities of rapid naming, reading rate, and accuracy. Brazilian bilingual students performed better in tasks of phonological memory in English and Brazilian Portuguese performed better in reading fluency. Different correlation patterns were found between the rapid naming, accuracy, and reading rate, in the bilingual group analysis, in both languages.

This study aimed at translating and adapting the Health-Care Waste Management - Rapid Assessment Tool (HCWM-RAT, proposed by the World Health Organization, to a Brazilian Portuguese version, and resolving its cultural and legal issues. The work focused on the evaluation of the concepts, items and semantic equivalence between the original tool and the Brazilian Portuguese version. Methods A cross-cultural adaptation methodology was used, including: initial translation to Brazilian Portuguese; back translation to English; syntheses of these translation versions; formation of an expert committee to achieve consensus about the preliminary version; and evaluation of the target audience’s comprehension. Results Both the translated and the original versions’ concepts, items and semantic equivalence are presented. The constructs in the original instrument were considered relevant and applicable to the Brazilian context. The Brazilian version of the tool has the potential to generate indicators, develop official database, feedback and subsidize political decisions at many geographical and organizational levels strengthening the Monitoring and evaluation (M&E mechanism. Moreover, the cross-cultural translation expands the usefulness of the instrument to Portuguese-speaking countries in developing regions. Conclusion The translated and original versions presented concept, item and semantic equivalence and can be applied to Brazil

This work presents the SEEG platform, a 46-year long dataset of greenhouse gas emissions (GHG) in Brazil (1970–2015) providing more than 2 million data records for the Agriculture, Energy, Industry, Waste and Land Use Change Sectors at national and subnational levels. The SEEG dataset was developed by the Climate Observatory, a Brazilian civil society initiative, based on the IPCC guidelines and Brazilian National Inventories embedded with country specific emission factors and processes, raw data from multiple official and non-official sources, and organized together with social and economic indicators. Once completed, the SEEG dataset was converted into a spreadsheet format and shared via web-platform that, by means of simple queries, allows users to search data by emission sources and country and state activities. Because of its effectiveness in producing and making available data on a consistent and accessible basis, SEEG may significantly increase the capacity of civil society, scientists and stakeholders to understand and anticipate trends related to GHG emissions as well as its implications to public policies in Brazil.

2018-01-01

The development of our society has been based on the use of biodiversity, especially for medicines and nutrition. Brazil is the nation with the largest biodiversity in the world accounting for more than 15% of all living species. The devastation of biodiversity in Brazil is critical and may not only cause the loss of species and genes that encode enzymes involved in the complex metabolism of organisms, but also the loss of a rich chemical diversity, which is a potential source for bioeconomy based on natural products and new synthetic derivatives. Bioeconomy focus on the use of bio-based products, instead of fossil-based ones and could address some of the important challenges faced by society. Considering the chemical and biological diversity of Brazil, this review highlights the Brazilian natural products that were successfully used to develop new products and the value of secondary metabolites from Brazilian biodiversity with potential application for new products and technologies. Additionally, we would like to address the importance of new technologies and scientific programs to support preservation policies, bioeconomy and strategies for the sustainable use of biodiversity.

The data are primary and were raised by a questionnaire application to nonprofits Portuguese organizations in 2009. The questions were grouped into three categories with eight questions for each group, whose intention was to map the elements related to Human Capital, Structural Capital and Relationships Capital. For the investigated elements quantification, a Likert scale was employed to detect the respondents’ agreement/disagreement degree in relation to the proposed statements. The results corroborate those from Colauto and Avelino (2008 and indicate the Portuguese organizations tendency to agree with the proposals for identifying the elements related to Human Capital, Structural Capital, and Relationships Capital. In the Portuguese organizations, the Human Capital was the category that showed the most significant results (mean of the concordance degree = 83%, while in the Brazilian organizations the greater emphasis was given to the Relationships Capital (mean of the concordance degree = 83%.

His performance applied to facilitate the interaction of DGE with its similar agencies in the federation. He idealized agreements with provincial statistical agencies; imagined counsels (or committees for making collective decisions; imagined a national statistical conference based on the experience he has accumulated in two conferences of the International Statistical Institute (ISI; applied attention to the formation of a statistical professional community; encouraged and sponsored the translation of books, among other measures. The Census of 1920, he had made, the only major census at the Early Brazilian Republic, was guided by friendly relations with the federal and provincial statistical organizations and with the society (Catholic Church, media, unions, clubs etc.. It was, we can say, a modern census, using processing machines, and concluded in a timely fashion. The printed volumes of results were illustrated by pictorial graphics, also used at the Pavilion of Statistics, called (by the press the Pavilion of Precisely Science, which fixed the presence of DGE in the International Exhibit of the Brazilian Independence Centennial (1822-1922. With his experience, anticipated the basis of Brazilian Institute of Geography and Statistics (IBGE, created in 1936 as the new Brazilian Statistical central agency (still working with growing success, that can be see, in sum, as a measure of his success in a long term vision.

Many studies point to a possible new stylized fact for financial time series: the multifractality. Several authors have already detected this characteristic in multiple time series in several countries. With that in mind and based on Multifractal Detrended Fluctuation Analysis (MFDFA) method, this paper analyzes the multifractality in the Brazilian market. This analysis is performed with daily data from IBOVESPA index (Brazilian stock exchange's main index) and other four highly marketable stocks in the Brazilian market (VALE5, ITUB4, BBDC4 and CIEL3), which represent more than 25% of the index composition, making up 1961 observations for each asset in the period from June 26 2009 to May 31 2017. We found that the studied stock prices and Brazilian index are multifractal, but that the multifractality degree is not the same for all the assets. The use of shuffled and surrogated series indicates that for the period and the actions considered the long-range correlations do not strongly influence the multifractality, but the distribution (fat tails) exerts a possible influence on IBOVESPA and CIEL3.

Inflammatory disorders are common in modern life, and medicinal plants provide an interesting source for new compounds bearing anti-inflammatory properties. In this regard, Brazilian medicinal plants are considered to be a promising supply of such compounds due to their great biodiversity. To undertake a review on Brazilian medicinal plants with corroborated anti-inflammatory activities by selecting data from the literature reporting the efficacy of plants used in folk medicine as anti-inflammatory, including the mechanisms of action of their extracts and isolated compounds. A search in the literature was undertaken by using the following Web tools: Web of Science, SciFinder, Pub-Med and Science Direct. The terms 'anti-inflammatory' and 'Brazilian medicinal plants' were used as keywords in search engine. Tropicos and Reflora websites were used to verify the origin of the plants, and only the native plants of Brazil were included in this review. The publications reporting the use of well-accepted scientific protocols to corroborate the anti-inflammatory activities of Brazilian medicinal plants with anti-inflammatory potential were considered. We selected 70 Brazilian medicinal plants with anti-inflammatory activity. The plants were grouped according to their anti-inflammatory mechanisms of action. The main mechanisms involved inflammatory mediators, such as interleukins (ILs), nuclear factor kappa B (NF-κB), prostaglandin E2 (PGE2), cyclooxygenase (COX) and reactive oxygen species (ROS). The collected data on Brazilian medicinal plants, in the form of crude extract and/or isolated compounds, showed significant anti-inflammatory activities involving different mechanisms of action, indicating Brazilian plants as an important source of anti-inflammatory compounds.

Smoking or health: the Brazilian option.

Lokschin, F; Barros, F C

Tobacco plays a key role in both disease and the economy in Brazil. In 1981 about 135 billion cigarettes were smoked, and cigarette-related diseases far outnumber infections as the leading cause of death. Brazil is the 4th largest world producer and the 2nd largest exporter of tobacco. 2.1% of the total population -- 2.5 million people -- are maintained by tobacco-related activities. Cigarette sales taxes provide 11.6% of the country's total taxes. Involved in a deep economic crisis, Brazil depends on this revenue and has not introduced any measures to control or counteract the high pressure marketing of cigarette manufacturers. Ischemic heart disease is the leading cause of death in Brazil, taking 90,000 lives in 1979. Based on World Health Organization estimates, at least 25% of these deaths could be ascribed to smoking. Cancer is the 2nd largest cause of death. In 1979, 10% of 60,000 cancer deaths were from lung cancer. Based on estimate that 30% of cancer deaths are provoked by smoking, more than 20,000 of those deaths were caused by tobacco. In Brazil, lung cancer is the 2nd highest cause of death from cancer in men and 3rd among women. Smoking in Brazil is definitely associated with low birth weight, the single most important predictive factor of perinatal and infant mortality. Rural workers giving up subsistence crops to grow tobacco may also affect their children's health. Also in such low-income populations, expenditures for cigarettes leave less money for essential goods. As a result of the high tax rate and the enormous number of cigarettes sold, 11.6% of all the country's revenue comes from the tobacco industry. The Brazilian Association of Tobacco Industries has been trying to link cigarette sales to Brazilian social development but does not mention the cost of disease, disability, and early death provoked by smoking. In Brazil tobacco companies have a huge market free of constraints, and the country lacks consistent smoking control policies. Recently

Full Text Available The text is the part of public policy of a larger research project on Brazilian Outward ForeignDirect Investment - OFDI. The text analyses the viability to adopt policies to enhance FDI,particularly outward. Based on statistical data and on literature review, the policy agenda framesthe underling questions surrounding the theme. There is not yet a theoretical framework to dealwith emergent countries’ FDI and related policies. There exist strong evidences that capital flowsthrough FDI generate externalities in the following domains: macroeconomics, microeconomicsand foreign relations particularly in areas related to industrial organization and innovation. Thetheoretical proposition is that international capital flows are compatible to monetary stability,commercial openness, investment promotion and industrial innovation policies. A betterpositioning of national enterprises internationally may result in growing partnership within theforeign environment. Brazil has not a set of policies to deal with inward and outward BrazilianFDI flows. These policies do not necessarily jeopardize macroeconomic policy and the relatedmonetary and currency stabilization goals. It contends that FDI stimulus by means of publicpolicies may contribute not just to a better competitiveness and innovation of Brazilianenterprises, but also assure a balanced growing and economic structural change.

An Unusual Partnership: Brazilian-Italian Forms of Cooperation in the Nuclear Field (1951-1986)

This chapter discusses the Brazilian-Italian cooperation in the nuclear field between the early 1950s and 1986. Since the late 1930s, Italian or Italian-Brazilian scientists promoted the development of studies in nuclear physics. Immediately after World War II, the Brazilian-Italian collaboration continued. Between the 1950s and the 1970s, Brazilian nuclear scientists studied in Italian institutions. Relying on primary sources from Brazilian archives and oral history interviews with protagonists of the Brazilian nuclear program, this chapter explore the relations between Italy and Brazil from 1951, the year of the establishment of the Brazilian nuclear program, until the 1980s. This study focuses on the bidirectional transfer of knowledge on sensitive technologies, and on the formal and informal cooperation between the two countries.

Does the Occasion Justify the Denunciation?: a Multilevel Approach for Brazilian Accountants

Bernardo de Abreu Guelber Fajardo

2014-01-01

Full Text Available Frauds represent large losses to the global economy, and one of the main means for their containment is by means of denunciations within organizations: whistle blowing. This research aims to analyze whistle blowing within the Brazilian context, considering the influence of costs and intrinsic benefits as well as aspects of the individual's interaction with his/her organization, profession and society at large. By means of a questionnaire answered by 124 accountants, a multilevel model was applied to analyze these aspects. The results demonstrate the importance of situational aspects as a positive influence in favor of denunciations. These results are useful for organizations and regulatory institutions in developing institutional mechanisms to encourage denunciation. Moreover, the results are also useful for teachers of professional ethics and members of the Federal and Regional Accounting Councils, which are dedicated to the assessment of alleged deviations from the professional code of ethics.

Brazilian foreign affairs: social capital and the democratic discourse in South America

Rafael Duarte Villa

Full Text Available Brazilian elites as well as foreign policy-makers have long shared a common belief that the ideas of democracy and democratization should serve as some "road map" to foreign policy-making. In areas such as security, regional integration, and disarmament, the goal has been to generate a positive social capital as well as to build trusting relations with Brazilian neighbors in South America. Therefore, under the impact of ideas brought about by new world visions, Brazilian foreign policy has changed a domestic policy feature - the democratic rearrangement of the political system - into a condition and resource for foreign policy-making towards South America. The result has been a fine improvement of Brazilian image and credibility in the regional South American scenario. In other words, there has been a significant increment in "trust" towards Brazil. This argument has been developed based on extracts and transcripts from official diplomatic speeches from Brazilian foreign policy-makers as well as a historical reconstruction of Brazil's diplomatic relations with two South American countries. Our study was based on two cases: Brazilian-Venezuelan and Brazilian-Argentine relations in the 80's and the 90's.

Recent advances in freshwater research indicate that the age of carbon exported from major rivers globally increases with greater human disturbance in the watershed. This implies that human land-use can release old, previously mineral-associated C into solution with subsequent export to groundwater and ultimately freshwater systems where terrestrial organic matter is either mineralized to CO2, stored in aquatic sediments, or exported to the ocean. It is important to understand the mechanisms that cause the release of mineral-bound soil organic matter (SOM) into solution in response to human disturbance and land-use change. To better characterize the response of the total soil organic matter (SOM) pool to disturbance, this study examines the interactions between dissolved and bulk soil pools in response to conversion of Brazilian Cerrado (savannah forest) to Eucalyptus plantations. Water-extractable organic matter (WEOM) was obtained from soil samples down to 150 cm at 4 sites in Sao Paulo State, Brazil. These WEOM samples were characterized using fluorescence and NMR spectroscopy, incubated to assess biolability, and carbon-dated. Simultaneously, bulk mineral soil samples were analyzed for microbial biomass, carbon content and age, and characterized using Fourier Transform Infrared Spectroscopy. FTIR spectra of SOM were obtained by washing subsamples with sodium hypochlorite and subtracting the subsequent mineral matrix spectra from bulk soil spectra. Preliminary results show that microbial biomass decreases much more quickly with depth than WEOM, suggesting that C released into solution from deeper horizons may be less likely to be intercepted, and thus preferentially leached to groundwater. Native Cerrado forests had substantially more roots compared to Eucalyptus, and also released substantially larger quantities of WEOM from their O horizons. Furthermore, the age of WEOM released under Eucalyptus forest was more similar in age to bulk SOM, while Cerrado forest

Full Text Available The vegetation of the Brazilian restinga (coastal woodland presents a variety of species and different characteristics, encompassing fields, fruit groves and forests on quartzarenic neosols. We hypothesised that the structure of the restinga landscape along the coast of the state of Piauí is influenced by edaphic factors and presents a pattern similar to that of other northeastern restingas. We evaluated three restingas in Piauí, using the quarter method to determine their structure. Composite soil samples were collected to determine their chemical and physical properties. Edaphic variables were correlated with plant species by canonical correspondence analysis (CCA. Phytosociological data for all three areas indicated regenerating vegetation comprising several small individuals, 82.5% of which showed a diameter at ground level < 13 cm. We also observed considerable tillering. In two of the areas, there was a predominance of Fabaceae species, such as Caesalpinia pyramidalis and Copaifera martii. Although the structural characteristics of the restingas studied were similar to those of other northeastern restingas, the former showed lower Shannon diversity indices (2.18-2.44. The CCA indicated that species distribution was influenced by edaphic factors such as pH, aluminium content and amount of organic matter. The restingas studied were similar to others along the Brazilian coast.

Full Text Available The objective of this study was to critically analyze the scientific production published in specialized Brazilian journals concerning the use of medicinal plants in dentistry. A literature review was carried out using an indirect documentation technique by means of a bibliographical study. Four examiners performed independent searches in Brazilian journals of medicinal plants indexed in the database SciELO (Brazilian Journal of Pharmacognosy; Brazilian Journal of Medicinal Plants; Brazilian Journal of Pharmaceutical Sciences; and Acta Botanica Brasilica using the descriptors "herbal medicine/phytotherapy" or "medicinal plants" and "dentistry ". The articles published from 2002 to 2012 addressing the use of medicinal plants in dentistry were included and analyzed. The searches based on the descriptors and reading of abstracts, resulted in 155 articles. Of these, 44 were read in full and a total of 16 publications met the eligibility criteria and were selected. Laboratory studies predominated (10 and were limited to the evaluation of antimicrobial properties by means of tests for determining inhibitory, fungicidal and bactericidal concentrations. Three literature reviews and only one clinical trial with no blinding and randomization were found. It is highlighted the need for better methodological designs in the researches and greater production of clinical or in vivo studies.

Collection and recycling of electronic scrap: A worldwide overview and comparison with the Brazilian situation

Highlights: ► Review of the different e-waste collection systems and recycling processes. ► We present the e-waste collection systems used in Europe and in the US. ► We present e-waste collection systems used in Asia and Latin America. ► E-waste management between developed and developing countries is very different. ► We made a comparison of the world situation to the current Brazilian reality. - Abstract: Recycling and the related issue of sustainable development are increasing in importance around the world. In Brazil, the new National Policy on Solid Wastes has prompted discussion on the future of electronic waste (e-waste). Over the last 10 years, different e-waste collection systems and recycling processes have been applied globally. This paper presents the systems used in different countries and compares the world situation to the current Brazilian reality. To establish a recycling process, it is necessary to organize efficient collection management. The main difficulty associated with the implementation of e-waste recycling processes in Brazil is the collection system, as its efficiency depends not only on the education and cooperation of the people but also on cooperation among industrial waste generators, distributors and the government. Over half a million waste pickers have been reported in Brazil and they are responsible for the success of metal scrap collection in the country. The country also has close to 2400 companies and cooperatives involved in recycling and scrap trading. On the other hand, the collection and recycling of e-waste is still incipient because e-wastes are not seen as valuable in the informal sector. The Brazilian challenge is therefore to organize a system of e-waste management including the informal sector without neglecting environmentally sound management principles.

Full Text Available Abstract Background Considering the importance of Executive Functions to clinical and nonclinical situations, Barkley proposed a new theory of executive functioning based on an evolutionary neuropsychological perspective and clinical research using large samples of clinical and community identified adults and children as well as children with ADHD followed to adulthood. Objective The present study aims to adapt the Barkley Deficits in Executive Functions Scales (BDEFS to Brazilian Portuguese and also assess its construct validity in a sample of normal Brazilian adults. Methods The original version of scale was adapted to Brazilian Portuguese according to the guideline from the ISPOR Task Force. To assess the semantic equivalence between the original and adapted version, both of them were applied into a sample of 25 Brazilian bilingual adults. Finally, 60 Brazilian adults completed the BDEFS and the Brazilian versions of Barratt Impulsiveness Scale (BIS-11 and Adult Self-Report Scale (ASRS-18 to assess convergent validity. Results The BDEFS Brazilian Portuguese version has semantic correspondence with the original version indicating that the adaptation procedure was successful. The BDEFS correlated significantly with the impulsivity and attention scores from the BIS-11 and ASRS-18 supporting its construct validity. Cronbach’s alpha (α = 0.961 indicated that the BDEFS translated version has satisfactory internal consistency. Discussion Together, these findings indicate the successful adaptation of the BDEFS to Brazilian Portuguese and support its utility in that population.

The Brazilian Microbiome Project (BMP) aims to assemble a Brazilian Metagenomic Consortium/Database. At present, many metagenomic projects underway in Brazil are widely known. Our goal in this initiative is to co-ordinate and standardize these together with new projects to come. It is estimated that Brazil hosts approximately 20 % of the entire world's macroorganism biological diversity. It is 1 of the 17 countries that share nearly 70 % of the world's catalogued animal and plant species, and is recognized as one of the most megadiverse countries. At the end of 2012, Brazil has joined GBIF (Global Biodiversity Information Facility), as associated member, to improve the access to the Brazilian biodiversity data in a free and open way. This was an important step toward increasing international collaboration and clearly shows the commitment of the Brazilian government in directing national policies toward sustainable development. Despite its importance, the Brazilian microbial diversity is still considered to be largely unknown, and it is clear that to maintain ecosystem dynamics and to sustainably manage land use, it is crucial to understand the biological and functional diversity of the system. This is the first attempt to collect and collate information about Brazilian microbial genetic and functional diversity in a systematic and holistic manner. The success of the BMP depends on a massive collaborative effort of both the Brazilian and international scientific communities, and therefore, we invite all colleagues to participate in this project.

Full Text Available An analysis of Brazilian federal expenditures in science and technology is presented is this study. The 1990-1999 data were compiled from records provided by two federal agencies (MCT and CNPq responsible for managing most of the national budget related to these activities. The results indicate that the federal investments in Brazilian science and technology stagnated during the last decade (US$ 2.32 billion in 1990, US$ 2.39 billion in 1996, and US$ 2.36 billion in 1999. In contrast, a great increase in private investments in research was acknowledged both by industry and by the government during the same period, from US$ 2.12 to US$ 4.64 billion. However, this investment did not result in an increase in invention patents granted to residents (492 in 1990 and only 232 in 1997 or in a reduction of patent costs. Despite this unfavorable scenario, the number of graduate programs in the country has increased two-fold in the last decade and the contribution of Brazilians to the database of the Institute for Scientific Information has increased 4.7-fold from 1990 (2,725 scientific publications to 2000 (12,686 scientific publications. Unstable federal resources for science, together with the poor returns of private resources in terms of developing new technologies, may jeopardize the future of Brazilian technological development.

Full Text Available OBJECTIVE: To detect the presence and concentration of methylparaben in cartridges of commercial Brazilian local anesthetics. MATERIAL AND METHODS: Twelve commercial brands (4 in glass and 8 in plastic cartridges of local anesthetic solutions for use in dentistry were purchased from the Brazilian market and analyzed. Different lots of the commercial brands were obtained in different Brazilian cities (Piracicaba, Campinas and São Paulo. Separation was performed using high performance liquid chromatography (HPLC with UV-Vis detector. The mobile phase used was acetonitrile:water (75:25 - v/v, pH 4.5, adjusted with acetic acid at a flow rate of 1.0 ml.min-1. RESULTS: When detected in the solutions, the methylparaben concentration ranged from 0.01% (m/v to 0.16% (m/v. One glass and all plastic cartridges presented methylparaben. CONCLUSION: 1. Methylparaben concentration varied among solutions from different manufacturers, and it was not indicated in the drug package inserts; 2. Since the presence of methylparaben in dental anesthetics is not regulated by the Brazilian National Health Surveillance Agency (ANVISA and this substance could cause allergic reactions, it is important to alert dentists about its possible presence.

In Brazil, the use of nuclear energy and radioisotopes is increasing and it already justifies the construction of a national repository for radioactive wastes of low and intermediate-level. The Brazilian National Commission for Nuclear Energy (CNEN) is legally responsible for designing and constructing intermediate and final storages for radioactive wastes generated in all Country, in accordance to Federal Law No. 10308. Additionally, the Brazilian Environmental Regulator (IBAMA) lately is imposing to the implementation of new nuclear installations (e.g. Angra 3 NPP and Brazilian Multipurpose Reactor) that the National Repository should be in construction, before the start-up of those ones. In November 2009, the RBMN Project Charter was signed. The RBMN Project aims at the implantation of a National Repository to dispose the radioactive wastes of low- and intermediate-level. Some aspects about the Repository construction are very challenging, mainly due to the licensing process, which will be made for two different regulatory bodies, nuclear and environmental. The main achievements obtained till now are the establishment of the current Brazilian radioactive waste inventory, the conceptual design and the selection of candidate sites for the repository. The current status of the Project is summarized. (author)

Since the first position statement on diabetes and cardiovascular prevention published in 2014 by the Brazilian Diabetes Society, the current view on primary and secondary prevention in diabetes has evolved as a result of new approaches on cardiovascular risk stratification, new cholesterol lowering drugs, and new anti-hyperglycemic drugs. Importantly, a pattern of risk heterogeneity has emerged, showing that not all diabetic patients are at high or very high risk. In fact, most younger patients who have no overt cardiovascular risk factors may be more adequately classified as being at intermediate or even low cardiovascular risk. Thus, there is a need for cardiovascular risk stratification in patients with diabetes. The present panel reviews the best current evidence and proposes a practical risk-based approach on treatment for patients with diabetes. The Brazilian Diabetes Society, the Brazilian Society of Cardiology, and the Brazilian Endocrinology and Metabolism Society gathered to form an expert panel including 28 cardiologists and endocrinologists to review the best available evidence and to draft up-to-date an evidence-based guideline with practical recommendations for risk stratification and prevention of cardiovascular disease in diabetes. The guideline includes 59 recommendations covering: (1) the impact of new anti-hyperglycemic drugs and new lipid lowering drugs on cardiovascular risk; (2) a guide to statin use, including new definitions of LDL-cholesterol and in non-HDL-cholesterol targets; (3) evaluation of silent myocardial ischemia and subclinical atherosclerosis in patients with diabetes; (4) hypertension treatment; and (5) the use of antiplatelet therapy. Diabetes is a heterogeneous disease. Although cardiovascular risk is increased in most patients, those without risk factors or evidence of sub-clinical atherosclerosis are at a lower risk.

2017-03-01

Full Text Available Anthropogenic forest disturbance and land use change (LUC in the Amazon region is the main source of greenhouse gas emissions to the atmosphere in Brazil, due to the carbon (C and nitrogen (N emitted from vegetation clearance. Land use conversion associated with management practices plays a key role in the distribution and origin of C in different soil organic matter (SOM fractions. Here, we show how changing land use systems have influenced soil C and N stocks, SOM physical fractions, and the origin of SOM in the Santarém region of the eastern Brazilian Amazon. Soil C and N stocks were calculated for the surface layer of 0–30 cm. Anthropogenic disturbances to the standing forest, such as selective logging and wildfires, led to significant declines in soil C and N stocks. However, in the long-term, the conversion of the Amazon forest to pasture did not have a noticeable effect on soil C and N stocks, presumably because of additional inputs from pasture grasses. However, the conversion to cropland did lead to reductions in soil C and N content. According to the physical fractionation of SOM, LUC altered SOM quality, but silt and clay remained the combined fraction that contributed the most to soil C storage. Our results emphasize the importance of implementing more sustainable forest management systems, whilst also calling further attention to the need for fire monitoring systems, helping to ensure the resilience of C and N stocks and sequestration in forest soils; thereby contributing towards urgently needed ongoing efforts to mitigate climate change.

Luso-Brazilian Enlightenment and the circulation of Caribbean slavery-related knowledge: the establishment of the Brazilian coffee culture from a comparative perspective.

Science.gov (United States)

Marquese, Rafael de Bivar

2009-01-01

The generation of enlightened Luso-Brazilians saw Caribbean slavery agriculture as the model to be emulated in Portuguese America. To do so, at the turn of the eighteenth to the nineteenth centuries, they translated and published some texts originally elaborated in the Antilles. In this reformist environment, the coffee culture occupied a place of prominence. To understand the role of this knowledge in establishing the Brazilian coffee culture, the Brazilian case is compared with the Cuban. The intent is to demonstrate that in the Spanish colony, the productive coffee plan of Santo Domingo was implanted, while in Brazil a plan was created, supported by new standards of agricultural management that were founded on local knowledge.

Energetic transition in the electric sector: Brazilian case

International Nuclear Information System (INIS)

Jannuzzi, Gilberto de Martino

1999-01-01

The Brazilian electric sector is essentially based on a source of renewable energy -hydroelectricity, and the national economy has increased its dependence of the electricity. The use of the electricity for unit of GDP increased in continuous form from 1970 and the country has serious difficulties in the financing of the expansion of the electric production. Energetic politics, in what concerns to the sustainable development in the Brazilian case, should direct its efforts toward a bigger investment in efficiency and energy conservation. a bigger use of supply options that they are renewable and decentralized will depend on high degree of the regulation of the electric sector during the privatization. The transition stage of the Brazilian electric sector will imply more efforts toward a handling based on the demand and a bigger efficiency

Full Text Available Abstract Objectives: To describe the circumstances of inclusion of female nurses in the Second World War through the Brazilian Air Force, and discuss the challenges faced by and the achievements of these nurses. Methods: Socio-historical study developed with textual and photographic sources, in addition to oral sources through interviews with war veterans. Data were treated according to the historical method and discussed with concepts support from the theory of social world, by Pierre Bourdieu. Results: The research has demonstrated that the inclusion of female nurses to the Air Force was characterized by social and symbolic effects of war demands and gender boundaries. Conclusion: The great challenge was the official incorporation of women by the Brazilian Air Forces in the post-war period. For this purpose, the organization of a flight female nurses cadre during the conflict was fundamental. Moreover, the record of this history reiterates the Nursing's legacy and the necessity of preparation for care in chaos situations.

Cristofoletti, Maria F; Gimeno, Suely G A; Ferreira, Sandra R G; Cardoso, Marly A

2013-08-01

The aim of this study was to investigate the association between the consumption of processed meat with overall, abdominal, and overall with abdominal obesity in a Japanese-Brazilian population, which is known to be at cardiometabolic risk. A total of 329 men and 443 women aged ≥ 30 years were evaluated in a cross-sectional population-based survey. Diagnosis of overall obesity and abdominal obesity were based on the World Health Organization (WHO) criteria for Asians. Food intake was assessed by a validated food frequency questionaire. In men, processed meat intake was positively associated with overall with abdominal obesity (OR 2.97; 95%CI 1.13-7.78) after adjustment. In women, only the red meat group was associated with overall with abdominal obesity after adjustment (OR 0.47, 95%CI 0.23-0.96). Our results showed that high intakes of processed meats were associated with overall with abdominal obesity in male Japanese-Brazilians, but not in females.

The Brazilian Societies of Rheumatology (SBR) and Dermatology (SBD), the Brazilian Federation of Gastroenterology (FBG) and the Brazilian Study Group on Inflammatory Bowel Disease (GEDIIB) gathered a group of their respective specialists on the topic of interest to discuss the most relevant issues regarding the clinical use of biosimilar medicines in Brazil. The main aim of that meeting was to prepare a document with recommendations to guide medical specialists and to help the national regulatory and policy-making agencies as concerns the authorization for marketing biosimilars used in autoimmune diseases, such as rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, Crohn's disease, juvenile idiopathic arthritis and ulcerative colitis. In addition to considerations on the typical differences between innovator medicines and biosimilars, the specialists established a set of seven recommendations on regulatory advances related to clinical studies, indication extrapolation, nomenclature, interchangeability, automatic substitution and pharmacovigilance.

Association of genetic variants with self-assessed color categories in Brazilians.

Directory of Open Access Journals (Sweden)

Danielle Fernandes Durso

Full Text Available The Brazilian population was formed by extensive admixture of three different ancestral roots: Amerindians, Europeans and Africans. Our previous work has shown that at an individual level, ancestry, as estimated using molecular markers, was a poor predictor of color in Brazilians. We now investigate if SNPs known to be associated with human skin pigmentation can be used to predict color in Brazilians. For that, we studied the association of fifteen SNPs, previously known to be linked with skin color, in 243 unrelated Brazilian individuals self-identified as White, Browns or Blacks from Rio de Janeiro and 212 unrelated Brazilian individuals self-identified as White or Blacks from São Paulo. The significance of association of SNP genotypes with self-assessed color was evaluated using partial regression analysis. After controlling for ancestry estimates as covariates, only four SNPs remained significantly associated with skin pigmentation: rs1426654 and rs2555364 within SLC24A5, rs16891982 at SLC45A2 and rs1042602 at TYR. These loci are known to be involved in melanin synthesis or transport of melanosomes. We found that neither genotypes of these SNPs, nor their combination with biogeographical ancestry in principal component analysis, could predict self-assessed color in Brazilians at an individual level. However, significant correlations did emerge at group level, demonstrating that even though elements other than skin, eye and hair pigmentation do influence self-assessed color in Brazilians, the sociological act of self-classification is still substantially dependent of genotype at these four SNPs.

Locative inversion and agreement syntax in Brazilian Portuguese

Full Text Available Adopting the Minimalist Program framework (CHOMSKY 2000, 2001, this paper suggests that, in Brazilian Portuguese, sentences with a locative prepositional phrase in preverbal position can be characterized as instances of locative inversion in which prepositional constituents occupy the grammatical subject position. It will be proposed that particularities involving the patterns of locative inversion in Brazilian Portuguese derive from properties of the subject-verb agreement in this language.

MARILIA VALLI

2018-04-01

Full Text Available ABSTRACT The development of our society has been based on the use of biodiversity, especially for medicines and nutrition. Brazil is the nation with the largest biodiversity in the world accounting for more than 15% of all living species. The devastation of biodiversity in Brazil is critical and may not only cause the loss of species and genes that encode enzymes involved in the complex metabolism of organisms, but also the loss of a rich chemical diversity, which is a potential source for bioeconomy based on natural products and new synthetic derivatives. Bioeconomy focus on the use of bio-based products, instead of fossil-based ones and could address some of the important challenges faced by society. Considering the chemical and biological diversity of Brazil, this review highlights the Brazilian natural products that were successfully used to develop new products and the value of secondary metabolites from Brazilian biodiversity with potential application for new products and technologies. Additionally, we would like to address the importance of new technologies and scientific programs to support preservation policies, bioeconomy and strategies for the sustainable use of biodiversity.

THE USE OF CATEGORIES AS INDICATORS OF ORGANIZATIONAL CLIMATE IN BRAZILIAN COMPANIES

Directory of Open Access Journals (Sweden)

Joel Souza Dutra

2012-04-01

Full Text Available In order to analyze employees’ perception of the work environment, companies with a well-established people management structure periodically conduct organizational climate surveys. These surveys are meant to offer an understanding of how employees view the quality of the relationships they experience in the company. One of the characteristics of this type of survey, identified both in the relevant literature and empirically in practice, is the use of categories or indicators to direct development of the research instrument, data analysis, and later intervention as needed according to the results of the survey. This article seeks to propose a categorization of organizational climate dimensions directed at the Brazilian corporate reality, analysing its internal consistency and its construct validity. To that end, we used the results of a wide-ranging data sample collected from 123,445 respondents of 491 organizations in various regions of Brazil. The proposed analysis categories – identity, satisfaction and motivation, learning and development, and leadership – were reviewed based on theories of organizational behavior and then submitted to a focus group composed of human resources professionals employed by prominent Brazilian corporations.

2014-03-01

The cyanobacterial community from Brazilian mangrove ecosystems was examined using a culture-dependent method. Fifty cyanobacterial strains were isolated from soil, water and periphytic samples collected from Cardoso Island and Bertioga mangroves using specific cyanobacterial culture media. Unicellular, homocytous and heterocytous morphotypes were recovered, representing five orders, seven families and eight genera (Synechococcus, Cyanobium, Cyanobacterium, Chlorogloea, Leptolyngbya, Phormidium, Nostoc and Microchaete). All of these novel mangrove strains had their 16S rRNA gene sequenced and BLAST analysis revealed sequence identities ranging from 92.5 to 99.7% when they were compared with other strains available in GenBank. The results showed a high variability of the 16S rRNA gene sequences among the genotypes that was not associated with the morphologies observed. Phylogenetic analyses showed several branches formed exclusively by some of these novel 16S rRNA gene sequences. BLAST and phylogeny analyses allowed for the identification of Nodosilinea and Oxynema strains, genera already known to exhibit poor morphological diacritic traits. In addition, several Nostoc and Leptolyngbya morphotypes of the mangrove strains may represent new generic entities, as they were distantly affiliated with true genera clades. The presence of non-ribosomal peptide synthetase, polyketide synthase, microcystin and saxitoxin genes were detected in 20.5%, 100%, 37.5% and 33.3%, respectively, of the 44 tested isolates. A total of 134 organic extracts obtained from 44 strains were tested against microorganisms, and 26% of the extracts showed some antimicrobial activity. This is the first polyphasic study of cultured cyanobacteria from Brazilian mangrove ecosystems using morphological, genetic and biological approaches. Copyright © 2014 Elsevier GmbH.

In this article, we present the Brazilian Portuguese Lexicon, a new word-based corpus for psycholinguistic and computational linguistic research in Brazilian Portuguese. We describe the corpus development, the specific characteristics on the internet site and database for user access. We also perform distributional analyses of the corpus and comparisons to other current databases. Our main objective was to provide a large, reliable, and useful word-based corpus with a dynamic, easy-to-use, and intuitive interface with free internet access for word and word-criteria searches. We used the Núcleo Interinstitucional de Linguística Computacional’s corpus as the basic data source and developed the Brazilian Portuguese Lexicon by deriving and adding metalinguistic and psycholinguistic information about Brazilian Portuguese words. We obtained a final corpus with more than 30 million word tokens, 215 thousand word types and 25 categories of information about each word. This corpus was made available on the internet via a free-access site with two search engines: a simple search and a complex search. The simple engine basically searches for a list of words, while the complex engine accepts all types of criteria in the corpus categories. The output result presents all entries found in the corpus with the criteria specified in the input search and can be downloaded as a.csv file. We created a module in the results that delivers basic statistics about each search. The Brazilian Portuguese Lexicon also provides a pseudoword engine and specific tools for linguistic and statistical analysis. Therefore, the Brazilian Portuguese Lexicon is a convenient instrument for stimulus search, selection, control, and manipulation in psycholinguistic experiments, as also it is a powerful database for computational linguistics research and language modeling related to lexicon distribution, functioning, and behavior.

Parlato-Oliveira, Erika; Christophe, Anne; Hirose, Yuki; Dupoux, Emmanuel

2010-06-01

Previous research shows that monolingual Japanese and Brazilian Portuguese listeners perceive illusory vowels (/u/ and /i/, respectively) within illegal sequences of consonants. Here, several populations of Japanese-Brazilian bilinguals are tested, using an explicit vowel identification task (experiment 1), and an implicit categorization and sequence recall task (experiment 2). Overall, second-generation immigrants, who first acquired Japanese at home and Brazilian during childhood (after age 4) showed a typical Brazilian pattern of result (and so did simultaneous bilinguals, who were exposed to both languages from birth on). In contrast, late bilinguals, who acquired their second language in adulthood, exhibited a pattern corresponding to their native language. In addition, an influence of the second language was observed in the explicit task of Exp. 1, but not in the implicit task used in Exp. 2, suggesting that second language experience affects mostly explicit or metalinguistic skills. These results are compared to other studies of phonological representations in adopted children or immigrants, and discussed in relation to the role of age of acquisition and sociolinguistic factors.

2006-05-01

Full Text Available The objective of this paper is to present and discuss Brazilian policy concerning actions to protect breastfeeding, especially the history, international and national background, limitations, and perspectives of the Brazilian Guidelines for the Marketing of Baby Food, Pacifiers and Bottles. The Brazilian Guidelines, which play a crucial role in protecting breastfeeding against industry marketing strategies, were based on the International Code of Marketing of Breastmilk Substitutes, proposed by the World Health Organization in 1981. The first version of the Brazilian Guidelines was released in 1988, and there were subsequent revisions in 1992 and 2001/2002. In 2006, the Guidelines became national law. However, the strides made over this period in terms of regulation have been few because the law is not always observed. Thus, it is essential that all actors involved, including government officials, manufacturers and sellers of baby food and other baby products, teaching and health professionals and their associations, international bodies, and non-governmental organizations make a commitment to enforce the current law.

Ten years of Brazilian ballast water management

Science.gov (United States)

Castro, Maria Cecilia Trindade; Hall-Spencer, Jason M.; Poggian, Cecília Fonseca; Fileman, Timothy W.

2018-03-01

In 2005, Brazil addressed the environmental challenges posed by ballast water through a unilateral regulation, called the Maritime Standard N° 20 (NORMAM-20), applied to all shipping in her waters. This world-leading decision was the culmination of a process that started during the 1990‧s. Here, we summarize how these ballast water regulations were brought in and adopted and present the findings of 10 years of enforcement (2005-2015) in 39 ports along the Brazilian coast. We show that compliance with the Brazilian standard has increased significantly since the regulations were implemented (p < 0.001). After five years of implementation, non-compliance decreased probably reflecting an increase in awareness of the Brazilian Standard and a shift in the shipping industry commitment to minimize and control the spread of invasive species through ballast water. The Brazilian experience shows that very high levels (97%) of compliance with ballast water management regulations can be made to work in a region of global importance to the maritime industry. In the last decade, the rules governing ballast water in Brazil have evolved to address the demands from the maritime community and to provide updates such as imminent requirements for the use of ballast water management systems on board ships. These regulations are rarely cited when ballast water regulations are discussed internationally, yet there is much to learn from the proactive approach taken by Brazil such as what is feasible and enforceable.

2017-11-01

Full Text Available This study aimed to compare the entry and operations strategies of franchisors of developed countries into foreign countries with Brazilian counterparts. Were there significant differences? An exploratory study was conducted with 16 international franchisors operating in Brazil and 31 Brazilian franchisors operating abroad. The results show that international franchisors operating abroad prefer to use a subsidiary in the destination country. At the same time, this strategy is little used by Brazilian franchisors, which prefer the strategy of direct franchises. For data collection, 47 directors or managers of the international expansion of Brazilian companies and the expansion directors of the international companies which operates in Brazil were interviewed. Although more expensive, the subsidiary in the target country offers greater control over the expansion of business reducing the problems caused by the distance of the country of origin. For the management of franchisors, this paper points out that the subsidiary is a natural evolution of entry and operation mode when it is desired or it is needed to control the expansion of networks in other countries. Thus, managers of franchisors in emerging countries should carefully examine the subsidiary option in the target country when their company considers accelerating international growth.

Climatically-mediated landcover change: impacts on Brazilian territory

Directory of Open Access Journals (Sweden)

MARINA ZANIN

Full Text Available ABSTRACT In the face of climate change threats, governments are drawing attention to policies for mitigating its effects on biodiversity. However, the lack of distribution data makes predictions at species level a difficult task, mainly in regions of higher biodiversity. To overcome this problem, we use native landcover as a surrogate biodiversity, because it can represent specialized habitat for species, and investigate the effects of future climate change on Brazilian biomes. We characterize the climatic niches of native landcover and use ecological niche modeling to predict the potential distribution under current and future climate scenarios. Our results highlight expansion of the distribution of open vegetation and the contraction of closed forests. Drier Brazilian biomes, like Caatinga and Cerrado, are predicted to expand their distributions, being the most resistant to climate change impacts. However, these would also be affected by losses of their closed forest enclaves and their habitat-specific or endemic species. Replacement by open vegetation and overall reductions are a considerable risk for closed forest, threatening Amazon and Atlantic forest biomes. Here, we evidence the impacts of climate change on Brazilian biomes, and draw attention to the necessity for management and attenuation plans to guarantee the future of Brazilian biodiversity.

Improving the effectiveness of impact assessment pertaining to Indigenous peoples in the Brazilian environmental licensing procedure

Hanna, Philippe; Vanclay, Frank; Langdon, Esther Jean; Arts, Jos

2014-01-01

The number of environmental licence applications for projects affecting Indigenous peoples in Brazil has increased since the implementation of a major infrastructure program (Programa de Aceleração do Crescimento) in 2007. This increase has caused problems for Brazilian agencies involved in environmental licensing procedures (IBAMA, FUNAI and others). We analyze the Brazilian environmental licensing procedure for situations involving Indigenous peoples, Maroons (Quilombolas) or other traditional communities in order to identify potential improvements for Brazil and potentially other countries. Although Brazilian procedures are consistent with international best practice in environmental licensing, in practice social impacts are inadequately addressed, mitigation measures are poorly implemented, and there is a lack of enforcement and compliance. The paper is based on document analysis and interviews with key actors in governmental and non-governmental organizations and Indigenous leaders. We suggest that Free, Prior and Informed Consent (FPIC) processes need to be conducted at the earliest stages of project planning, and that Indigenous peoples should actively participate in impact assessment, monitoring and evaluation processes. In order to achieve a social licence to operate, there needs to be full recognition of traditional knowledge and acceptance of Indigenous values and concepts. We also recommend increased involvement of social experts and mediators as well as improved accountability, enforcement and grievance mechanisms in the licensing process. - Highlights: • The Brazilian environmental licensing system needs to address social impacts better. • Communities need to be consulted at the earliest stage possible. • Indigenous peoples need to be invited to participate in impact assessment teams. • Independent Indigenous committees to monitor implementation of mitigation measures. • Accountability, enforcement and grievance mechanisms need to be

After attempting to explain why successive challengers have not been able to change the structure of competition for the Brazilian presidency, I will analyze the relation established between the pattern observed at this level and the other “connected” electoral disputes—both those for state executive and federal legislative office. The general conclusion is that even if the pattern continues, it is quite improbable that this will significantly impact the other levels of national political party competition.

Full Text Available The research aims to answer the following question: What is the effectiveness of mergers and acquisitions in the Brazilian market as external corporate governance mechanism? The main objective of the study is to verify if mergers and acquisitions operations in Brazilian market may act as an external mechanism of corporate governance, replacing managers and, as a consequence of changes in management, improving financial performance. The study is exploratory, qualitative in its approach, supported by documentary research on secondary data concerning an intentional sample of Brazilian companies aiming to identify the effect of M&A operations on the corporate governance structure of the acquired firm and on its financial results. Data obtained on the website of the Brazilian Securities and Exchange Commission (CVM, related to Brazilian M&A operations in the period 2005-2010, were analyzed. Although M&A operations in Brazil were found to have disciplinary nature in our sample of firms in the studied period, our results are inconclusive regarding the effectiveness of these transactions and external governance mechanisms.

Full Text Available The pasture is an important economic activity in the brazilian Savannah. From the 1970s and 1980s, the implementation of the programs to improve the productivity of pastures, was introduced grasses, especially Brachiaria. When handled properly, the pasture is an efficient method to contribute to carbon sequestration and to the mitigation of concentrations of greenhouse gases in the atmosphere, which are dependent to the time of the land-use and the properties of each soil type. The microregion of Uberlandia in Triangulo Mineiro (MG is traditionally linked to the pasture. However, the geological and natural soil conditions and climate are factors that can accelerate soil degradation when pasture is not handled properly. The objective of this article was to compare the changes of soil properties and the incorporation of C in covered areas [1] natural brazilian Savannah, [2] mixed system initially converted to agricultural use and the last 15 years of pasture, and [3] pasture cultivated with 30 years of implantation. The results show the influence of the land use on organic matter dynamics, and evaluate the potential degradation of soil by the activity, management and time of land use.

The uranium mining is one of the main activities of the nuclear fuel cycle that can contribute to the increased exposure to radioactive materials and is one of the main routes of contamination of soil by natural radionuclides. This study investigated the sorption of uranium in brazilian soils, through sorption isotherms performed in batch. In this study, two types of soils were selected: Ferralsols Red and Nitosol. The adjustment of the experimental data to the kinetic models were evaluated by two approaches: the traditional, based on the coefficient of determination (R 2 ); and the theoretical and informative, based on Corrected Akaike Information Criteria (AIC C ). The coefficient of determination (R 2 ), revealed that, although empirical, both the kinetic model, Freundlich and Langmuir, describes satisfactorily the experimental data, showing R 2 values higher than 0.9, while the partition constant model was not suitable for describe these sorption data. The AICC model analysis showed that the Langmuir model fit the U sorption curve well for Ferralsols Red, while the Freundlich model fits better to Nitosol. This study has highlighted the role of organic matter on the sorption of uranium in highly weathered soils, rich in oxyhydroxides and low activity clays. The Kd values reported in this study differ from those recommended by the United States Environmental Protection Agency, therefore must be considered as reference values for highly weathered soils, since it refers to Brazilian pedoenvironmental conditions. The low Kd values obtained in this study allowed to evaluate the high vulnerability of highly weathered soils to uranium contamination. (author)

Patients infected with the human immunodeficiency virus (HIV) have generally been excluded from consideration for liver transplantation. Recent advances in the management and prognosis of these patients suggest that this policy must be reevaluated. To identify the current position of Brazilian transplant centers concerning liver transplantation in asymptomatic HIV-infected patients with end-stage liver disease. A structured questionnaire was submitted by e-mail to Brazilian groups who perform liver transplantation and were active in late 2003, according to the Brazilian Association of Organ Transplantation. Of the 53 active groups, 30 e-mail addresses have been found of professionals working in 41 of these groups. Twenty-one responses (70%) were obtained. Most of the professionals (62%) reported that they do not include HIV-infected patients in waiting lists for transplants, primarily on account of the limited world experience. They also reported, however, that this issue will soon be discussed by the group. Those who accept these patients usually follow the guidelines provided by the literature: patients must fulfill the same inclusion criteria as the other patients with end-stage liver diseases, present low or undetectable HIV viral load, and a CD4 count above 250/mm3. They reported that there are 10 HIV-infected patients in waiting list and that only one patient has received a liver transplant in the country. Most centers do not accept in waiting lists for liver transplantation patients with HIV infection, even asymptomatic ones. However, advances in the management of HIV-infected patients suggest that this policy must be reevaluated. In Brazil, there is practically no experience in liver transplantation in HIV-positive patients.

To develop and validate a Brazilian Portuguese version of the Premenstrual Symptoms Screening Tool (PSST), a questionnaire used for the screening of premenstrual syndrome (PMS) and of the most severe form of PMS, premenstrual dysphoric disorder (PMDD). The PSST also rates the impact of premenstrual symptoms on daily activities. A consecutive sample of 801 women aged ≥ 18 years completed the study protocol. The internal consistency, test-retest reliability, and content validity of the Brazilian PSST were determined. The independent association of a positive screen for PMS or PMDD and quality of life determined by the World Health Organization Quality of Life instrument-Abbreviated version (WHOQOL-Bref) was also assessed. Of 801 participants, 132 (16.5%) had a positive screening for PMDD. The Brazilian PSST had adequate internal consistency (Cronbach's alpha = 0.91) and test-retest reliability. The PSST also had adequate convergent/discriminant validity, without redundancy. Content validity ratio and content validity index were 0.61 and 0.94 respectively. Finally, a positive screen for PMS/PMDD was associated with worse WHOQOL-Bref scores. These findings suggest that PSST is a reliable and valid instrument to screen for PMS/PMDD in Brazilian women.

Tiago Filho, Geraldo Lucio; Rocha Galhardo, Camila; Cassia Barbosa, Adriana de; Mambeli Barros, Regina; Gracas Braga da Silva, Fernando das

2011-01-01

This article presents the main regulatory changes that occurred in the Brazilian power sector in 2009, along with the impacts these changes caused on the market, especially related to small hydropower (<30 MW). This study addresses regulatory issues based on inventory studies and records of basic projects, changes related to the compensation of the assured energy of SHPs in the Brazilian energy reallocation market, the socio-economic impact resulting from the construction of SHPs, SHPs in alternative resource auctions and finally the general outlook for the growth scenario for SHPs in Brazil according to the ten-year plan (2010-2019). The overall conclusions of this investigation were that the 2008/2009 biennium was a period of great changes in the regulation of small hydropower plants in Brazil, and the SHP market has shown maturity. Additionally, despite SHP being a type of technology that is completely dominated by domestic industry, in recent years, they have experienced policy disincentives caused by changes to rules that inhibit their growth. - Highlights: → Main regulatory changes in Brazilian Power Sector that have occurred in 2009. → The impact of these changes caused on market, especially about SHPs (<30 MW). → The Brazilian growth scenario for SHPs according to the ten-year plan (2010-2019). → 2008/2009 biennium was a period of changes in the Brazilian regulation of SHPs. → SHP is a type of technology that is completely dominated by domestic industry.

The Colombian side of the colombian-brazilian border. An approach using the category of lawless area

Luis Fernando Trejos Rosero

2015-01-01

Full Text Available This study uses the category of lawless areas as an approach to the complex security situation resulting from increasing ties between localized criminality and transnational organized crime networks on the Colombian side of the Colombian-Brazilian border. The permanent presence of illegal armed actors in this border area is largely caused by the absence and weak presence of the Colombian State at its margins. The methodology used is both bibliographic and descriptive.

The role of interest rates in the Brazilian business cycles

Directory of Open Access Journals (Sweden)

Nelson F. Souza-Sobrinho

2011-09-01

Full Text Available This paper offers additional insights on the relationship between interest rates and business cycles in Brazil. First, I document that Brazilian interest rates are very volatile, counter-cyclical and positively correlated with net exports, as observed in other emerging market economies. Next, I present a dynamic stochastic general equilibrium model in which firms face working capital constraints and labor supply is independent of consumption. This parsimonious model, appropriately calibrated to the Brazilian economy, predicts that interest rate shocks can explain about one third of output fluctuations and delivers business cycle regularities consistent with the Brazilian data.

Full Text Available We report here the first complete mitochondria genome of Onchocerca volvulus from a focus outside of Africa. An O. volvulus mitogenome from the Brazilian Amazonia focus was obtained using a combination of high-throughput and Sanger sequencing technologies. Comparisons made between this mitochondrial genome and publicly available mitochondrial sequences identified 46 variant nucleotide positions and suggested that our Brazilian mitogenome is more closely related to Cameroon-origin mitochondria than West African-origin mitochondria. As well as providing insights into the origins of Latin American onchocerciasis, the Brazilian Amazonia focus mitogenome may also have value as an epidemiological resource.

The Health Service Quality Scale is a multidimensional hierarchical scale that is based on interdisciplinary approach. This instrument was specifically created for measuring health service quality based on marketing and health care concepts. The aim of this study was to translate and culturally adapt the Health Service Quality Scale into Brazilian Portuguese and to assess the validity and reliability of the Brazilian Portuguese version of the instrument. We conducted a cross-sectional, observational study, with public health system patients in a Brazilian university hospital. Validity was assessed using Pearson's correlation coefficient to measure the strength of the association between the Brazilian Portuguese version of the instrument and the SERVQUAL scale. Internal consistency was evaluated using Cronbach's alpha coefficient; the intraclass (ICC) and Pearson's correlation coefficients were used for test-retest reliability. One hundred and sixteen consecutive postoperative patients completed the questionnaire. Pearson's correlation coefficient for validity was 0.20. Cronbach's alpha for the first and second administrations of the final version of the instrument were 0.982 and 0.986, respectively. For test-retest reliability, Pearson's correlation coefficient was 0.89 and ICC was 0.90. The culturally adapted, Brazilian Portuguese version of the Health Service Quality Scale is a valid and reliable instrument to measure health service quality.

Full Text Available Background: Immigrants face many challenges when settling in a foreign country, numerous factors influence this immigrant experience including the resources they bring with them and those they find in the host society. The literature has indicated that a significant number of individuals migrate in search of a better quality of life. In this context, the objective of the study was to analyze the quality of life and health of Brazilian immigrants living in Portugal, using the "Medical Outcomes Study: 36-Item Short Form Survey" (SF-36. Methods and Results: A cross-sectional study with a quantitative approach developed under the project titled: Health status and quality of life of Brazilian immigrants in Portugal conducted in the first half of 2016, with 682 Brazilian immigrant women over 18 living in Portugal. This study adopted as reference SF-36, a generic instrument for the evaluation of Quality of Life. It can be affirmed that the quality of life and health of Brazilian immigrants living in Portugal is good, since all dimensions presented values above 50%. It was evidenced that Brazilian immigrants who live alone have lower levels of quality of life and health than those who live with someone and, that Brazilian immigrants who are unemployed, have low levels of quality of life and health compared to those who are in another employment situation, and Brazilian immigrants entering the labor market with a workload of more than 40 hours per week present similar levels of quality of life and health compared to those who work fewer hours. Conclusion: In general, one can affirm that the quality of life and health of Brazilian immigrants living in Portugal is good, but due to the particularities of the migration process in the current political and international context, a systematic monitoring of living conditions and health of this population is necessary.

Karla Cristina Silva Sousa

2018-01-01

Full Text Available The article discusses the relationship between state and federalism as a political and administrative organizational form of the state and its implications in Brazilian educational policy. For that, we follow the analysis of the concepts of State, federalism, and educational policies from the classics of Machiavelli (2001, Locke (1998, Rousseau (1999, Hamilton, Jay and Madison (2003, Abrucio Arretche (1996, among others. Therefore, we see that the new Brazilian federalism based on the model proposed by the American Constitution brings the local powers – the municipalities – as new agents within the educational policy and the collaboration regime as a means of effecting cooperative federalism in Brazil. We conclude that the federalism, in Brazilian model, presents itself as demos constraining the national sub-governments.

The Brazilian Public Health in Contemporary Capitalism.

Junqueira, Virgínia; Mendes, Áquilas N

2018-01-01

This article examines some political and economic facts that led to an intensification of austerity measures by the Brazilian government, including ones against the Unified Health System (SUS) and its progressive dismantling. In a country where fundamental human rights were never fully respected, nowadays social and labor rights are under severe attacks. The deepening of the capital crisis and the rise of interest-bearing capital dominance have been causing unemployment, social insecurity growth, and resulting public fund appropriation by the private capital. The Brazilian governments in the 1990s and 2000s have implemented deeper cuts in social policy expenditure, freezing security benefits, privatizing services, and prioritizing the payment of public debt interests. The right wing's project involves the demoralization of not only the Workers' Party but also the left as a whole, so that the adoption of austerity measures could be achieved without popular resistance. It is the duty of the Brazilian left wing to denounce such a project and to provoke firm initiatives to rebuild its bonds with the working class.

Alternative fuels: a Brazilian outlook

Moreira, J.R.; Serra, G.E.

1990-01-01

This paper focuses on studies and information related to the use of alternative fuels in Brazil. The first part of this paper deals with the economics of different biomass technologies. The analysis consists of a careful costing of all operations involved. The study deals with wood, sugar cane and cassava, since these crops are exploited for commercial purposes in Brazil. Corn, although a useful raw material for producing ethanol in the United States, is not used for this purpose in Brazil. The second part deals with the industrial technologies used to convert biomass into energy. We consider several forms of energy derived from biomass and evaluate the economics of the processes. When opportune, we compare costs with those of the North American market. Market analysis and displacement of conventional energy are the subject of the third part of the paper. While the cost of each product is evaluated in most cases; in others the current market price is used. Finally, we raise the issues of institutional problems and planning and offer some conclusions on the future of biomass as an alternative energy source. The technological discussion in this paper is based on the Brazilian experience in producing ethanol and other fuels from biomass. It is possible to extrapolate the Brazilian experience to other developing countries. The observations made in this chapter are based on the conditions prevalent in the Brazilian south-central agricultural region, specifically the state of Sao Paulo.

2003-08-01

We have performed observations of the sky alongside with the Indians of all Brazilian regions that made it possible localize many indigenous constellations. Some of these constellations are the same as the other South American Indians and Australian aborigines constellations. The scientific community does not have much of this information, which may be lost in one or two generations. In this work, we present a planetary-observatory that we have made in the Park of Science Newton Freire-Maia of Paraná State, in order to popularize the astronomical knowledge of the Brazilian Indians. The planetary consists, essentially, of a sphere of six meters in diameter and a projection cylinder of indigenous constellations. In this planetary we can identify a lot of constellations that we have gotten from the Brazilian Indians; for instance, the four seasonal constellations: the Tapir (spring), the Old Man (summer), the Deer (autumn) and the Rhea (winter). A two-meter height wooden staff that is posted vertically on the horizontal ground similar to a Gnomon and stones aligned with the cardinal points and the soltices directions constitutes the observatory. A stone circle of ten meters in diameter surrounds the staff and the aligned stones. During the day we observe the Sun apparent motions and at night the indigenous constellations. Due to the great community interest in our work, we are designing an itinerant indigenous planetary-observatory to be used in other cities mainly by indigenous and primary schools teachers.

On the certification of forest concession: non-governmental organizations, enterprises, and the construction of a new institutional frame for the development of the lumber industry in the Brazilian Amazon

Marcelo Sampaio Carneiro

2011-12-01

Full Text Available The article discusses the construction process of forest certification in the Brazilian Amazon, emphasizing its importance for the new frame of lumber industry on that region. We sustain that one of the main results of the promotion of forest certification by the Forest Stewardship Council (FSC in Amazon was the constitution of an alliance between the environmentalist Non-Governmental Organizations, representative segments of forest business and members of the state bureaucracy for the promotion of lumber exploration based on forest management. In this perspective, the results produced by certification must be understood as part of a process of promotion of forest resources access policies, such as the approval of the Public Forests Management Law, and the creation of state entities destined to the promotion of lumber extraction on Amazon.

A total of 730 adolescents participated in the study, 482 Brazilian (213 boys and 269 girls with average age of 15 years (SD= 1.1 and 238 Portuguese (117 boys and 121 girls with average age of 15.4 years (SD= 1.8. In both samples, the PVQ-24 showed satisfactory internal consistency, and the proposed factor structure was confirmed (four systems: materialistic, religious, hedonistic, and post-materialist. The post-materialist system was organized into three subsystems: social well-being, individual well-being and occupational well-being. In both samples, confirmatory factor analysis and multidimensional scaling supported the hypotheses regarding content (four systems and three subsystems, structure (two dimensions and compatibility (positive correlations between systems.

Treatment of drug dependence with Brazilian herbal medicines

Directory of Open Access Journals (Sweden)

Elisaldo A. Carlini

Full Text Available The topic "Herbal Medicines in the Treatment of Addictions" in a country must be preceded by answers to four questions: 1. Does the country in question possess a biodiversity rich enough to allow the discovery of useful medicines? 2. Do local people have tradition and culture to look for and use resources from Nature to alleviate and cure diseases, including drug dependence? 3. Is drug dependence (or addiction present in the country in question? 4. Do people of that country recognize and diagnose such problem as a serious one? Alcohol is, by far, the most serious health problem when drug abuse is considered, reaching all of Brazilian society, including the Indians. On the contrary, other drugs may be considered as minor problems and they are not the main focus of this manuscript. The people living in Brazilian hinterland don’t have access to public health systems. Consequently, these people seek assistance from "curandeiros" and "raizeiros"; the Indians are assisted by the shaman. These "folk doctors" do not know the academic medicine and therapeutics, and resort to the local plants to treat different ailments of their patients. Furthermore, alcohol abuse and dependence are not recognized by them, according to the rules and criteria of academic medicine. We have conducted a survey in many Brazilian books, Thesis concerning phytotherapy, and several databank. The results of such searches were very disappointing. No published papers from Brazilian authors concerning the use of plants for the treatment of addictions were found in the databases and there were only three very short notes in the masterly book written by Shultes and Raffauf (1990. From the Brazilian books on folk medicine employing medicinal plants, ten mentions were disclosed: most of them dealing with treatment of alcohol problems and two to counteract "Ayahuasca" dependence.

Pharmacogenomic diversity among Brazilians: Influence of ancestry, self-reported Color and geographical origin

Full Text Available By virtue of being the product of the genetic admixture of three ancestral roots: Europeans, Africans and Amerindians, the present day Brazilian population displays very high levels of genomic diversity, which have important pharmacogenetic/-genomic (PGx implications. Recognition of this fact has prompted the creation of the Brazilian Pharmacogenomics Network (Refargen, a nationwide consortium of research groups, with the mission to provide leadership in PGx research and education in Brazil, with a population heath impact. Here, we present original data and review published results from a Refargen comprehensive study of the distribution of PGx polymorphisms in a representative cohort of the Brazilian people, comprising 1,034 healthy, unrelated adults, self-identified as white, brown or black, according to the Color categories adopted by the Brazilian Census. Multinomial log-linear regression analysis was applied to infer the statistical association between allele, genotype and haplotype distributions among Brazilians (response variables and self-reported Color, geographical region and biogeographical ancestry (explanatory variables, whereas Wright´s FST statistics was used to assess the extent of PGx divergence among different strata of the Brazilian population. Major PGx implications of these findings are: first, extrapolation of data from relatively well-defined ethnic groups is clearly not applicable to the majority of Brazilians; second, the frequency distribution of polymorphisms in several pharmacogenes of clinical relevance (e.g. ABCB1, CYP3A5, CYP2C9, VKORC varies continuously among Brazilians and is not captured by race/Color self-identification; third, the intrinsic heterogeneity of the Brazilian population must be acknowledged in the design and interpretation of PGx studies in order to avoid spurious conclusions based on improper matching of study cohorts.

Article-level metrics and the periphery: an exploration of articles by Brazilian authors

Energy Technology Data Exchange (ETDEWEB)

Souza, I.V.P.; Gouveia, F.C.

2016-07-01

This work-in-progress paper describes an ongoing PhD study that aims to explore article-level metrics from a set of articles published by Brazilian researchers. It is argued that article-level metrics can offer a more nuanced and accurate picture of the influence of a particular work in comparison to journal-level metrics. However, if these new metrics rely on sources that exclude a large part of research from the periphery, they are at risk of simply preserving the present inequalities in the scholarly communication system. In order to understand how article-level metrics are or could be useful to the scientific community in the peripheries, we need to see what metrics are currently available, identify possible biases, and understand their meaning. We aim to contribute to this discussion with a case study focused on exploring a set of both traditional and alternative article-level metrics related to publications authored by Brazilian researchers. So far, few studies analyse article-level metrics for Brazilian publications, and most focus on Brazilian journals instead of researcher's affiliation. Our study will collect articles with DOIs registered by Brazilian researchers at the Lattes Platform, an information system maintained by the national Science, Technologies and Communications ministry. This exploration aims to address the following questions: (a) Which are the main article-level metrics available for journal articles authored by Brazilian researchers? What are the main sources of ALM data for Brazilian publications?; (b) Are there any disciplines, institutions, locations etc. that attract more mentions in the case of Brazilian articles? How do these metrics compare among themselves?; and (c) Do articlelevel metrics of publications by Brazilian researchers reflect patterns and trends observed in studies with researchers from other countries?

2009-01-01

We reviewed the key steps in the launch of the Vida Verde Women's Co-Op among Brazilian immigrant housecleaners in Somerville, MA. The co-op provides green housecleaning products, encourages healthy work practices, and promotes a sense of community among its members. We conducted in-depth interviews with 8 of the first co-op members, who reported a reduction in symptoms associated with the use of traditional cleaning agents and a new sense of mutual support. Critical to the co-op's success have been the supportive roles of its academic partners (Tufts University and the University of Massachusetts, Lowell), effective media outreach, and a focus on advancing social justice. Next steps include implementing a formal business plan and assessing the appropriateness of cooperatives in other industries. PMID:19890146

The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak of expiratory flow (PEF), forced expiratory flow at 50% (FEF50%), 75% average vital capacity (FEF25-75%), and average forced expiratory flow time (FEFT). This was a prospective study using results from chest radiographs, electrocardiograms, and questionnaires to investigate the participants' respiratory symptoms, sedentarism, and comorbidities (Charlson comorbidity index). From December 2010 to July 2014, individuals were randomly selected from various locations in the state of Rio de Janeiro. All individuals were examined by a single technician in the morning at the laboratory, and performed the spirometry with the same spirometer. Spirometry values were tabulated for the creation of three equation models: linear regression, logarithmic regression, and logarithms through a method that incorporates the lambda, median, and coefficient of variation (LMS method). Initially, 7003 individuals from both genders were contacted, and 454 were recruited. The data from the new equations were compared with one Brazilian and eight international equations, resulting in a high correlation (r>0.9). The values derived from the LMS method and linear regression were very similar (P>0.5), and both could be used to acquire the reference values for Brazilian spirometry. Data derived from the equations of this study were different from the current Brazilian equation, which could be justified by the different method used.

The aims of the current study were 1) to evaluate the reliability and validity of the Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale and 2) to investigate the quality of life of Brazilian patients with myasthenia gravis and its determinants. This cross-sectional study included 69 patients with myasthenia gravis who underwent neurological evaluation and completed questionnaires regarding quality of life (the 36-item Short Form of the Medical Outcomes Study and the 15-item Myasthenia Gravis Quality of Life Scale), anxiety and depressive symptoms. The Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale showed high internal consistency and good concurrent validity with the 36-item Short Form of the Medical Outcomes Study and its subscales. Determinants of quality of life in Brazilian patients with myasthenia gravis included the current status of myasthenia gravis as assessed by the Myasthenia Gravis Composite, the current prednisone dose and the levels of anxiety and depression. The Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale is a valid instrument. Symptom severity, prednisone dosage and anxiety and depression levels impact the quality of life of patients with myasthenia gravis.

[Brazilian colonization in the Paraguayan agricultural frontier].

Science.gov (United States)

Neupert, R F

1991-04-01

This work briefly describes Brazilian colonization of the Paraguayan agricultural frontier, analyzes factors responsible for expelling population from Brazil and for attracting Brazilians to Paraguay, and assesses the economic and social consequences of immigration to the area. Paraguay's vast and sparsely populated agricultural frontier in areas outside the Central subregion underwent a process of intense colonization from the early 1960s to the mid-1980s. The Paraguayan government initiated an ambitious colonization program in 1963 to increase production, relieve population pressure and subdivision of small parcels in the Central subregion, encourage agricultural modernization, and produce a more diversified agriculture. Paraguayan agriculture in the early 1960s suffered from excessive concentration of land in a few hands and resulting exclusion of around 3/4 of workers from ownership and from any possibility of obtaining credit to fund technological improvements. Results of studies 2 decades after implementation of the colonization plan suggest that it has failed in significant areas. Although a considerable population redistribution alleviated pressure in the Central subregion, it apparently resulted more from spontaneous movement of peasants outside the colonization areas than from the official program. Concentration of lands is now occurring in the colonization area. Assistance for agricultural modernization and diversification of production in the peasant sector has been minimal. On the other hand, production of soy, wheat, and cotton for export increased substantially, because of an entrepreneurial agriculture capitalized by foreign as well as national interests The unmet goals of the colonization program would have required structural reforms rather than simple spatial redistribution of the population. Many of the colonists in the 1970s were Brazilian families displaced by mechanized agriculture in the southern states of Parana, Santa Catarina, and Rio

THE PROCESS OF INTERNATIONALIZATION OF BRAZILIAN FIRMS: STUDY WITH FRANCHISORS

2012-01-01

Full Text Available The purpose of this study is to analyze the process of internationalization of Brazilian firms, including the motivations for the internationalization, the modes of entry and the difficulties faced during this process. This research is relevant due to the importance of international management for Brazilian firms at the current global scenario. Firstly, it was developed a theoretical basis and, afterwards, an empirical qualitative and exploratory research was carried out. The data were collected from in depth interviews with the representatives of ten Brazilian franchisors that became international, which are associated to the Brazilian Association of Franchising (ABF, who gave support to the research. The analytical procedure adopted was the content analysis. Franchising was chosen because Brazil is one of the most developed countries in this field and franchising is recognized as an important booster of the globalization process. The interviews were conducted with either the owner of the firm or the marketing or international executive officers. The results of the empirical research show that, although Brazilian firms are late movers, the firms analyzed do not seem handicapped in terms of managerial capacity or technological competences. It is clear, nevertheless, that they are late movers because they have a huge internal market to explore. Adopting a global vision is very important, even if they prefer a gradual approach towards internationalization.

Health service quality scale: Brazilian Portuguese translation, reliability and validity

Science.gov (United States)

2013-01-01

Background The Health Service Quality Scale is a multidimensional hierarchical scale that is based on interdisciplinary approach. This instrument was specifically created for measuring health service quality based on marketing and health care concepts. The aim of this study was to translate and culturally adapt the Health Service Quality Scale into Brazilian Portuguese and to assess the validity and reliability of the Brazilian Portuguese version of the instrument. Methods We conducted a cross-sectional, observational study, with public health system patients in a Brazilian university hospital. Validity was assessed using Pearson’s correlation coefficient to measure the strength of the association between the Brazilian Portuguese version of the instrument and the SERVQUAL scale. Internal consistency was evaluated using Cronbach’s alpha coefficient; the intraclass (ICC) and Pearson’s correlation coefficients were used for test-retest reliability. Results One hundred and sixteen consecutive postoperative patients completed the questionnaire. Pearson’s correlation coefficient for validity was 0.20. Cronbach's alpha for the first and second administrations of the final version of the instrument were 0.982 and 0.986, respectively. For test-retest reliability, Pearson’s correlation coefficient was 0.89 and ICC was 0.90. Conclusions The culturally adapted, Brazilian Portuguese version of the Health Service Quality Scale is a valid and reliable instrument to measure health service quality. PMID:23327598

The widespread use of pesticides in agriculture can lead to water contamination and cause adverse effects on non-target organisms. Brazil has been the world's top pesticide market consumer since 2008, with 381 approved pesticides for crop use. This study provides a comprehensive literature review on the occurrence of pesticide residues in Brazilian freshwaters. We searched for information in official agency records and peer-reviewed scientific literature. Risk quotients were calculated to assess the potential risk posed to aquatic life by the individual pesticides based on their levels of water contamination. Studies about the occurrence of pesticides in freshwaters in Brazil are scarce and concentrated in few sampling sites in 5 of the 27 states. Herbicides (21) accounted for the majority of the substances investigated, followed by fungicides (11), insecticides (10) and plant growth regulators (1). Insecticides are the class of major concern. Brazil would benefit from the implementation of a nationwide pesticide freshwater monitoring program to support preventive, remediation and enforcement actions.

Integrating Ecosystem Management, Protected Areas, and Mammal Conservation in the Brazilian Amazon

Directory of Open Access Journals (Sweden)

Claudia Azevedo-Ramos

2006-12-01

Full Text Available The Amazon forest has been converted to a matrix of pristine and modified habitats. Landscape-scale biodiversity conservation requires an understanding of species' distributions over this matrix to guarantee both effective protection and use for present and future generations. In this study, we evaluated how much of the existing and future planned protected areas (PAs would be contributing to the conservation of Brazilian Amazon mammals (N = 399, including threatened species (N = 51. Currently, almost 37% of Brazilian Amazon is protected and that may increase to 46% if planned PAs are implemented. In the current PA system, 22% are indigenous land and 11% are sustainable use units, e.g., production forests. Only one-fifth of the whole range of mammal species occurring in Brazilian Amazon is actually protected by Brazilian PAs. However, considering only the part of the ranges within the Brazilian Amazon, and therefore under the scope of Brazilian actions, Brazilian PAs assume an important role in the protection of 39% of mammal distribution ranges, particularly the threatened species (39%. These results suggest that an integrated network of protected areas among Amazon countries would be necessary to increase their efficiency in mammal conservation. The need for strengthening of the forest sector and good management practices in Brazil appears critical for the maintenance of large extents of forest and species conservation. Under such a scenario, the contribution of developed nations and international agencies must assume an important role for the maintenance and enlargement of the protected area network in Amazon region.

Full Text Available The Bolsa Escola (‘school stipend’ and its successor the Bolsa Familia (‘family stipend’ schemes have formed a crucial and successful part of Brazil’s welfare program. Bolsa Escola provided aid to Brazil’s poorest families on the condition that their children attended school, and Bolsa Familia has extended this idea, giving aid on the condition that children both attend school and receive vaccinations. Bolsa Familia is currently the largest Conditional Cash Transfer Program (CCTP in the world, costing roughly 0.5% of Brazilian GDP and helping around 11.2 million families (around 44 million Brazilians, constituting roughly one fifth of the population. Multilateral institutions have praised the schemes, and they are setting a leading example to other developing nations. In 2005, Paul Wolfowitz (former president of the World Bank said, ‘Bolsa Familia has already become a highly praised model of effective social policy. Countries around the world are drawing lessons from Brazil’s experience and are trying to produce the same results for their own people’.

Polymer nanocomposites have been shown to possess better properties when compared with traditional composites. This study aims to investigate the effects of the addition of organophilic clay and Brazilian nut fiber on the polypropylene (PP). First, 5%, 10% and 20% PP/compatibilizer maleic anhydride (PP-g-MA) by weight was added to Pure PP, respectively. From the results, 5% PP-g-MA was defined for preparing the nanocomposites. Samples were prepared containing 5% PP / PP-g-MA reinforced with 5% organophilic Brazilian smectite clay and 5%, 10% and 15% Brazilian nut fiber. Specimens were tested for tensile strength and impact. The materials were characterized by laser diffraction particle size and X-ray diffraction, and the nanocomposites, by mechanical strength and impact. The best result was obtained by inserting 15% fiber. (author)

I present distribution data of all Dactyloidae, Hoplocercidae, Iguanidae, Leiosauridae, Polychrotidae and Tropiduridae lizards known from the Brazilian Amazonia, totaling 40 species-level taxa, belonging to 11 genera. This represents four more species-level taxa than previously reported for these families. Data were based on the direct examination of 41,243 specimens deposited in three North American and eight Brazilian musea, including the main collections harboring Amazonian material. Most species (62.5%) are endemic to the Amazonia; non-endemic species are mainly associated with open dry (semideciduous) forest or open vegetation (savanna) enclaves in Amazonia, with a few exceptions. As a whole, seven taxa are widespread in Amazonia, one is restricted to eastern Amazonia, three to western Amazonia, five to northern Amazonia (either in part of it or widespread in the Guiana region), two to northwestern Amazonia, one to southern Amazonia, nine to southwestern Amazonia, and seven to the southern peripheral portion of Amazonia. Five species have unique distributions and five species have a distribution that is congruent with one of the areas of endemism (AE) recognized for other organisms (birds and primates). The first herpetological gazetteer for the Brazilian Amazonia with about 3,600 georeferenced localities was also produced.

Systematic risk variations (beta convertible debenture brazilian companies

2010-01-01

Full Text Available purpose of this article is to analyze the impact of issuing convertible debentures on the systematic risk of Brazilian companies. Some applied researches in the U.S. capital market (STEIN, 1992; LEWIS et al, 2002; RAI, 2005 indicate that convertible debentures may be used as an alternative financing source when adverse selection problem makes stock issuing unattractive financing source. The analysis of Brazilian companies that issued convertible debentures recorded in the period from 1998 to 2006 and that presented liquidity on the market indicated that variation in beta, on average, is positive. These results are coherent with the signaling hypothesis and with the absence of convertible debenture issuing in 2005 and 2006 on the Brazilian market. They also may be related to the precarious financial situation of issuing companies, observed by the analysis of some financial indicators in year of issue and in two pre- e post-issuing years.

Full Text Available As in many national cinemas, the history of Brazilian amateur film is still in its early stages of investigation. In addition to this historiographical deficit, there are many ways in which amateur cinema is a small and less visible production: films shot in 16mm, 9.5mm and Super 8 are dispensable and Brazilian film archives and cinemateques only started cataloguing these materials in recent years. In the following paper we wish to establish a set of theoretic and historical guidelines to analyse amateur films that express different forms of amateur production. Through the collection of home movies from Alves de Lima family deposited at Cinemateca Brasileira (São Paulo, the amateur fictional films from Cinemateca Capitólio (Porto Alegre and Raymond Chauvin's  experimental films belonging to Hipólito José da Costa Communications Museum (Porto Alegre we want to give visibility to films that are not yet part of Brazilian cinema history.

Full Text Available ABSTRACT OBJECTIVE To characterize the current stage of the institutionalization of pharmaceutical services in Brazilian cities. METHODS This study is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines, a cross-sectional, exploratory, and evaluative study composed by an information survey in a representative sample of cities, stratified by Brazilian regions. We interviewed municipal secretaries of health, responsible for pharmaceutical services, and pharmacists responsible for the dispensing of medicines. The variables selected from the interviews were grouped into five dimensions that defined three stages of pharmaceutical services institutionalization: incipient (0%-34.0%, partial (35.0%-69.0%, and advanced (70.0%-100%, estimated based on the interviewees’ answers. Frequencies were estimated with 95% confidence intervals. For the statistical association analysis, the Chi-square test was applied, with significance level of p<0.05. RESULTS Our results show a partial and heterogeneous process of institutionalization of pharmaceutical services in Brazil, and an advanced stage in formal structures, such as the municipal health plans and the existence of a standardized list of medicines. The analysed variables in the “organization, structure, and financing” dimension configured stages that range from partial to advanced. The management presented partial institutionalization, positively showing the existence of computerized system, but also disparate results regarding the autonomy in the management of financial resources. Indispensable items related to the structure expressed disparities between the regions, with statistically significant differences. CONCLUSION The study showed a partial and heterogeneous process of institutionalization of pharmaceutical services in Brazilian cities, showing regional

The biodiversity of the Amazon forest is undoubtedly rich; hence there is considerable variety of plant fibers regarding their morphological, chemical and structural properties. The legal exploration of the Brazilian Amazon is based on sustainable management techniques, but the generation of a relevant amount of plant wastes still cant be avoided. The correct destination of such materials is a challenge that Brazilian companies have to face. In this context, the National Council of Science and Technology (CNPq) promoted the creation of investigation nets on sustainability of Brazilian agribusiness. The Brazilian Net on Lignocellulosic Composites and Nanocomposites was then created, with partnership between several national and international research institutions. Until the moment, the results showed that Amazon plant fibers that are discarded as residues have great potential to nanofiber production. Nanopapers with considerable high mechanical and physical strength, proper opacity and great crystalline index were produced by using a clean and simple mechanical method. Those materials are candidates to several uses such as packaging, substrates transparent conductive films, gas barrier films, solar cells and e-papers

Stevens, Jens T; Beckage, Brian

2009-10-01

* Fire disturbance can mediate the invasion of ecological communities by nonnative species. Nonnative plants that modify existing fire regimes may initiate a positive feedback that can facilitate their continued invasion. Fire-sensitive plants may successfully invade pyrogenic landscapes if they can inhibit fire in the landscape. * Here, we investigated whether the invasive shrub Brazilian pepper (Schinus terebinthifolius) can initiate a fire-suppression feedback in a fire-dependent pine savanna ecosystem in the southeastern USA. * We found that prescribed burns caused significant (30-45%) mortality of Brazilian pepper at low densities and that savannas with more frequent fires contained less Brazilian pepper. However, high densities of Brazilian pepper reduced fire temperature by up to 200 degrees C, and experienced as much as 80% lower mortality. * A cellular automaton model was used to demonstrate that frequent fire may control low-density populations, but that Brazilian pepper may reach a sufficient density during fire-free periods to initiate a positive feedback that reduces the frequency of fire and converts the savanna to an invasive-dominated forest.

2009-01-01

As an active Member State of the International Atomic Energy Agency (IAEA), Brazil has applied substantial resources in order to maintain the best possible cooperation with the Agency, aiming at a continuous improvement of the effectiveness and efficiency of the safeguards system. Over the last decades a number of projects, involving the participation of high-level Brazilian professionals in the nuclear area, have already been jointly completed. To continue providing this voluntary support to the IAEA Department of Safeguards for research, development and implementation, in 2006 Brazil decided to accept the IAEA's invitation to participate in the IAEA Member States Support Programmes initiative, which currently includes 21 Member States. The Research and Development (R and D) Programme for Nuclear Verification is the IAEA reference in this regard, establishing the high priority needs and describing each recognized departmental project. The Programme is issued every two years. The 'Brazilian Support Programme (BRZ SP)' was established on the basis of a set of administrative procedures titled 'Cooperation Arrangements and Guidelines', agreed between the Brazilian National Nuclear Energy Commission (CNEN) and the IAEA - Department of Safeguards. The scope of the BRZ SP includes: the participation in field tests and the evaluation of state-of-the-art technologies as requested by the IAEA for its safeguards applications; the training of safeguards personnel involved with safeguards implementation at both facility and State levels; laboratorial support in the area of destructive and nondestructive analysis of nuclear materials; the analysis of safeguards issues; information acquisition, analysis and evaluation; and the provision of human resources, such as experts and consultants to work directly with the IAEA Secretariat. The activities agreed under the BRZ SP are not restricted to CNEN staff members. Professionals from other Brazilian organizations may also be involved

Estimating the efficiency from Brazilian banks: a bootstrapped Data Envelopment Analysis (DEA

Ana Elisa Périco

2016-01-01

Full Text Available Abstract The Brazilian banking sector went through several changes in its structure over the past few years. Such changes are related to fusions and acquisitions, as well as the largest market opening to foreign banks. The objective of this paper is to analyze, by applying the bootstrap DEA, the efficiency of banks in Brazil in 2010-2013. The methodology was applied to 30 largest banking organizations in a financial intermediation approach. In that model, the resources entering a bank in the form of deposits and total assets are classified as inputs and besides these manual labor is also considered as a resource capable of generating results. For the output variable, credit operations represent the most appropriate alternative, considering the role of the bank as a financial intermediary. In this work, the matter of the best classification among retail banks and banks specialized in credit has little relevance. The low relevance in this type of comparison is a result of analysis by segments (segments were analyzed separately. The results presented here point to an average level of efficiency for the large Brazilian banks in the period. This scenario requires efforts to reduce expenses but also to increase revenues.

Selenium and total and organic mercury were determined in the liver and kidney of franciscana dolphin (Pontoporia blainvillei) incidentally caught in fishing nets along two Brazilian coastal areas (southeast and south). Regional differences in the concentrations of these contaminants were observed in P. blainvillei. Liver showed the highest organic and total mercury. In general, samples of individuals collected at the southern of Brazil had the highest concentrations of selenium and total and organic mercury. No significant gender differences were observed. Growth stage influenced the accumulation of these contaminants in both organs, and hepatic concentrations increased with the body length, according to the sampling area. Molar mercury and selenium concentrations in liver were significantly correlated, with a Se:Hg ratio close to 4. The among-site differences we found may be related to differences in preferred prey, bioavailability in the marine environment, environmental conditions, or these individuals may belong to distinct populations. - This study presents some useful data on the bioaccumulation of Hg, organic Hg and Se, and their inter-element relationships in a Brazilian small cetacean

Selenium and total and organic mercury were determined in the liver and kidney of franciscana dolphin (Pontoporia blainvillei) incidentally caught in fishing nets along two Brazilian coastal areas (southeast and south). Regional differences in the concentrations of these contaminants were observed in P. blainvillei. Liver showed the highest organic and total mercury. In general, samples of individuals collected at the southern of Brazil had the highest concentrations of selenium and total and organic mercury. No significant gender differences were observed. Growth stage influenced the accumulation of these contaminants in both organs, and hepatic concentrations increased with the body length, according to the sampling area. Molar mercury and selenium concentrations in liver were significantly correlated, with a Se:Hg ratio close to 4. The among-site differences we found may be related to differences in preferred prey, bioavailability in the marine environment, environmental conditions, or these individuals may belong to distinct populations. - This study presents some useful data on the bioaccumulation of Hg, organic Hg and Se, and their inter-element relationships in a Brazilian small cetacean.

The Idea of Science of Brazilian Physiologist Miguel Ozório de Almeida (1890-1953

Full Text Available Epistemological considerations of philosophers and scientists from the late nineteenth century to the mid-twentieth century guided Brazilian physiologist Miguel Ozório de Almeida (1890-1953 in formulating his researches and participating in national and international scientific debates. With his siblings, Álvaro Ozório de Almeida and Branca de Almeida Fialho, he participated in debates on Brazilian educational and scientific system’s reform and in international organizations. The family’s residence in Rio de Janeiro housed a laboratory that became a reference in experimental physiology researches in Brazil. This article aims to present Miguel Ozório de Almeida’s conception of science, constructed mainly within the private laboratory’s sociability, providing new aspects of scientific work production in Brazil in the early twentieth century. I argue that Ozório de Almeida’s stand as an internationalist physiologist in national and international contexts was related to his reading of texts by Ernest Mach, Pierre Duhem, Henri Poincaré and William James.

Using the results of dozens of interviews with key actors involved in tobacco control policymaking, we examine these actors' perceptions of threats to tobacco control policy efforts from international economic policies on trade and investment. We also evaluate, from a legal perspective, the genuine threats that exist or potential challenges that economic policies may pose to the Brazilian government's public health efforts. We find that most actors did not perceive these economic policies as a major threat to tobacco control. Objectively, we found that some threats do exist. For example, Brazil's attempt to ban most tobacco additives and flavorings continues to met resistance at the World Trade Organization.

Full text: The Brazilian research reactors have a limited capacity for radioisotopes production, leading to a high dependence on external supply for radioisotopes used in nuclear medicine. In order to overcome this condition and due to the old age of these research reactors, the Brazilian Nuclear Energy Commission decided, in 2008, to construct a new research reactor. The new reactor named RMB (Brazilian Multipurpose Reactor) will be part of a new nuclear research center, to be built on a site about 100 kilometers from São Paulo city, in the southern part of Brazil. The new nuclear research center will have a 30 MW open pool type research reactor using low enriched uranium fuel, and several associated laboratories in order to produce radioisotopes for medical and industrial use, to use neutron beams in scientific and technological research; to perform neutron activation analysis; and to perform materials and fuels irradiation tests. Regarding the neutron beams use, the RMB design provides thermal and cold neutron beams. From one side of the reactor, the neutron guides will extend to an experimental hall of instruments named Neutron Guide Hall where it will be installed the scattering instruments. In the initial stage of the reactor operation, the intent is to implement two neutron guides for thermal neutrons and another two for cold neutrons. The 2015 SBPMAT symposium has presented the technical overview of the RMB project and its main buildings, structures and components. At this year symposium, the RMB presentation updates some technical information and the development status of the project, discussing the negative results of the Brazilian political and economic crisis to the project development and its future perspectives.

Brazil generated 326 TWh of hydroelectric power in 2005, accounting for ∼81% of the electricity production for that year. The 2005 to 2030 projections for the Brazilian development indicate growths from 2,020 kWh to 4,380 kWh in the per capita electricity consumption and from US$4,300 to US$8,950 in the per capita GDP (in market exchange rate and 2005 US$). The consumption of electricity is to grow from 375 TWh in 2005 to 1,030 TWh in 2030. In simple view and without considerations of aspects related with energy efficiency, this growth means 1.8 times the generation capacity of the 20. century should be built along of 25 years of the 21. century. The Brazilian electricity generation will demand all primary sources to meet the foreseen growth of the electricity consumption. As economical, safe and clean primary energy source for electricity generation, the nuclear energy is one option capable of large-scale and short-term deployment in the Brazilian growth of the electricity consumption. The contribution of nuclear generation in the electricity consumption should evolve from the current 2.6% for amounts over 5% in 2030. The perspective of the Brazilian nuclear sector is evolving to be resumed and present an opportunity for pooling and rationalizing the available skills - technical, cultural and human. The role of business opportunities and the future demands in the value chain of nuclear activities are summarized in this document. Institutions of R and D and Brazilian universities play an important role for the formation of new demanded knowledge and human resources. (authors)

Full Text Available The objective of this study was to assess the quality of lunch consumed by adults in Brazil and its sociodemographic determinants in each Brazilian region. A cross-sectional study was carried out and a representative sample of regional populations was used. The sample comprised of 16,096 adults from the Brazilian National Dietary Survey, part of the Brazilian Household Budget Survey (POF. The lunch quality was evaluated by applying the main meal quality index (MMQI, comprised of 10 items of equal weights that resulted in a score that ranged from zero to 100 points. Linear regression models measured the association between lunch quality and sociodemographic factors. The average energy consumption at lunch was 704kcal (SD = 300, and the meal quality score mean was 57 points (SE = 0.30. The North Region had the worst MMQI score (56 points, SE = 0.07, while the Central had the best MMQI adjusted score (59 points, SE = 0.05. The MMQI final score was positively associated with male gender and ages between 20-39 years, and was inversely associated with having eight years or more of education, per capita income of at least three minimum wages, and with the consumption of meals prepared away from home. Despite differences among sociodemographic factors, all Brazilian regions had a lunch composed of foods rich in sugars and fats, with insufficient portions of fruits and vegetables, resulting in a low meal quality.

Full Text Available OBJECTIVE: To evaluate the effectiveness of the Brazilian Cardioprotective Diet Program in reducing blood pressures, fasting glucose levels and body mass indices in patients with established atherothrombotic disease. METHOD: This randomized controlled pilot trial included outpatients who were over 45 years of age with atherothrombotic cardiovascular disease. Group A, who received the Brazilian Cardioprotective Diet Program, had weekly sessions with dietitians. Groups B and C received the usual dietary therapy that is given to patients with cardiovascular diseases as proposed by the Brazilian guidelines. This diet had the same nutrient profile as that given to Group A, but it was customized by the integration of typical Mediterranean foods. The difference between Groups B and C was the number of sessions with the dietitian. Group B received weekly sessions, while group C only had monthly sessions. ClinicalTrials.gov: NCT 01453166. RESULTS: There was a greater reduction in systolic (7.8% and diastolic (10.8% blood pressures in Group A compared with Group B (2.3% and 7.3%, and Group C (3.9% and 4.9%, respectively. Fasting glucose decreased by 5.3% and 2% in Groups A and B, respectively. Fasting glucose increased by 3.7% in Group C. The BMIs decreased by 3.5% and 3.3% in Groups A and B, respectively. Group C did not present with any changes in BMI. However, none of these data showed statistical differences between the groups, which is methodologically acceptable in pilot trials. CONCLUSIONS: The Brazilian Cardioprotective Diet Program seems to be more effective in reducing blood pressures, fasting glucose levels, weights and BMIs in patients with previous cardiovascular disease compared with the diet that has been proposed by the Brazilian guidelines.

COMPARATIVE EVIDENCE ABOUT KNOWLEDGE TRANSFER BETWEEN BRAZILIAN AND FOREIGN FRANCHISE COMPANIES

2012-01-01

Full Text Available The objective of this study is to compare the process of transferring knowledge in franchising between Brazilian and international companies operating in Brazil. Franchising has shown an important phenomenon in many countries, with considerable evidence of growing globally. It is a new type of business organization as an object of academic research field offering great reviews, but also limitations as references and studies of depth of field. The traditional literature in management emphasis on franchising, in large part to its importance as a way to circumvent resource constraints, as their characteristics and definition of business practices among its different parts. The transfer of knowledge in franchising is still a gap especially among companies in different countries. In addition, we adopted a methodology that this study followed a qualitative research with in-depth interviews of franchisees. The results show that Brazilian firms oriented transfer of knowledge in franchising for more lawsuits based on tacit knowledge, thus using more informal and less number of transfer mechanisms in these processes. International companies operating in Brazil for franchising rely on formal processes with periodic meetings, training and technological resources, and therefore have a greater control over the process of transferring knowledge to the franchised units. Thus, this study seeks to help we better understand franchising, development processes and their expansion in emerging markets like Brazil.

Full Text Available Whereas an initial step in the management of stakeholders is the identification and classification of these actors, this study sought to answer the research question: how managers of Brazilian professional soccer clubs identify and classify their stakeholders? The theoretical framework used was the Stakeholder Theory, developed by Freeman (1984 and other researchers. The method used was proposed by Almeida et al. (2000, which assesses the saliency through the concepts power, legitimacy and urgency, that were proposed in the study of Mitchell et al. (1997. There were two propositions concerning the context of Brazilian soccer clubs: first, that the urgency perceived by managers in the demands of a stakeholder is high when his legitimacy is high and other one is that the most salient stakeholders for the managers are those with high degrees of legitimacy. Stakeholders were surveyed as perceived by the managers of Sociedade Esportiva Palmeiras. Three types of stakeholders were classified as demanding (sponsors, partners and the partner for the construction of the new stadium and three as dependents (members, athletes of professional soccer team and the media. Other stakeholders identified were classified as irrelevant, including the fans and and the organized groups of fans. It can be said that in the specific case of these managers of this particular football club, the trend was the acceptance of both propositions.

The uranium mining is one of the main activities of the nuclear fuel cycle that can contribute to the increased exposure to radioactive materials and is one of the main routes of contamination of soil by natural radionuclides. This study investigated the sorption of uranium in brazilian soils, through sorption isotherms performed in batch. In this study, two types of soils were selected: Ferralsols Red and Nitosol. The adjustment of the experimental data to the kinetic models were evaluated by two approaches: the traditional, based on the coefficient of determination (R{sup 2}); and the theoretical and informative, based on Corrected Akaike Information Criteria (AIC{sub C}). The coefficient of determination (R{sup 2}), revealed that, although empirical, both the kinetic model, Freundlich and Langmuir, describes satisfactorily the experimental data, showing R{sup 2} values higher than 0.9, while the partition constant model was not suitable for describe these sorption data. The AICC model analysis showed that the Langmuir model fit the U sorption curve well for Ferralsols Red, while the Freundlich model fits better to Nitosol. This study has highlighted the role of organic matter on the sorption of uranium in highly weathered soils, rich in oxyhydroxides and low activity clays. The Kd values reported in this study differ from those recommended by the United States Environmental Protection Agency, therefore must be considered as reference values for highly weathered soils, since it refers to Brazilian pedoenvironmental conditions. The low Kd values obtained in this study allowed to evaluate the high vulnerability of highly weathered soils to uranium contamination. (author)

Full Text Available This paper reports a study on politeness strategies of Brazilian Portuguese speakers and American English speakers regarding their responses to compliments. The aim of this research is to gain an insight into the politeness characteristics of Brazilian Portuguese speakers by analyzing how Brazilian students react when receiving compliments. It also aims to investigate how politeness from Brazilian Portuguese speakers differs from politeness of American English speakers when receiving compliments. The population for this research consists of 12 students with intermediate and upper-intermediate levels of EFL from the Cooperative de Trabalho Magna, a private school in Brazil. The study followed a descriptive and interpretive qualitative research method, where 133 answers were analyzed and then contrasted with Chen’s (1993 study of politeness strategies between American English and Chinese speakers. This study shows that, unlike American English speakers, Brazilian Portuguese speakers need to justify and give reasons for the compliment received.

Full Text Available Propolis contains a variety of bioactive components and possesses many biological properties. This study was designed to evaluate potential effects of Brazilian green propolis on glucose metabolism and antioxidant function in patients with type 2 diabetes mellitus (T2DM. In the 18-week randomized controlled study, enrolled patients with T2DM were randomly assigned to Brazilian green propolis group (900 mg/day (n = 32 and control group (n = 33. At the end of the study, no significant difference was found in serum glucose, glycosylated hemoglobin, insulin, aldose reductase or adiponectin between the two groups. However, serum GSH and total polyphenols were significantly increased, and serum carbonyls and lactate dehydrogenase activity were significantly reduced in the Brazilian green propolis group. Serum TNF-α was significantly decreased, whereas serum IL-1β and IL-6 were significantly increased in the Brazilian green propolis group. It is concluded that Brazilian green propolis is effective in improving antioxidant function in T2DM patients.

Comparative genomic analysis of Brazilian Leptospira kirschneri serogroup Pomona serovar Mozdok

Directory of Open Access Journals (Sweden)

Luisa Z Moreno

2016-08-01

Full Text Available Leptospira kirschneri is one of the pathogenic species of the Leptospira genus. Human and animal infection from L. kirschneri gained further attention over the last few decades. Here we present the isolation and characterisation of Brazilian L. kirschneri serogroup Pomona serovar Mozdok strain M36/05 and the comparative genomic analysis with Brazilian human strain 61H. The M36/05 strain caused pulmonary hemorrhagic lesions in the hamster model, showing high virulence. The studied genomes presented high symmetrical identity and the in silico multilocus sequence typing analysis resulted in a new allelic profile (ST101 that so far has only been associated with the Brazilian L. kirschneri serogroup Pomona serovar Mozdok strains. Considering the environmental conditions and high genomic similarity observed between strains, we suggest the existence of a Brazilian L. kirschneri serogroup Pomona serovar Mozdok lineage that could represent a high public health risk; further studies are necessary to confirm the lineage significance and distribution.

2009-01-01

Aims: The genetic diversity of Beauveria bassiana was investigated by comparing isolates of this species to each other (49 from different geographical regions of Brazil and 4 from USA) and to other Beauveria spp. Methods and Results: The isolates were examined by multilocus enzyme electrophoresis (MLEE), amplified fragment length polymorphism (AFLP), and rDNA sequencing. MLEE and AFLP revealed considerable genetic variability among B. bassiana isolates. Several isolates from South and Southeast Brazil had high similarity coefficients, providing evidence of at least one population with clonal structure. There were clear genomic differences between most Brazilian and USA B. bassiana isolates. A Mantel test using data generated by AFLP provided evidence that greater geographical distances were associated with higher genetic distances. AFLP and rDNA sequencing demonstrated notable genotypic variation between B. bassiana and other Beauveria spp. Conclusion: Geographical distance between populations apparently is an important factor influencing genotypic variability among B. bassiana populations in Brazil. Significance and Impact of the Study: This study characterized many B. bassiana isolates. The results indicate that certain Brazilian isolates are considerably different from others and possibly should be regarded as separate species from B. bassiana sensu latu. The information on genetic variation among the Brazilian isolates, therefore, will be important to comprehending the population structure of B. bassiana in Brazil. ?? 2009 The Society for Applied Microbiology.

Computational modeling of the mathematical dummy of the Brazilian woman for calculations of internal dosimetry and ends of comparison of the fractions absorbed specific with the woman reference

International Nuclear Information System (INIS)

Ximenes, Edmir

2006-01-01

Tools for dosimetric calculations are of the utmost importance for the basic principles of radiological protection, not only in nuclear medicine, but also in other scientific calculations. In this work a mathematical model of the Brazilian woman is developed in order to be used as a basis for calculations of Specific Absorbed Fractions (SAFs) in internal organs and in the skeleton, in accord with the objectives of diagnosis or therapy in nuclear medicine. The model developed here is similar in form to that of Snyder, but modified to be more relevant to the case of the Brazilian woman. To do this, the formalism of the Monte Carlo method was used by means of the ALGAM- 97 R computational code. As a contribution to the objectives of this thesis, we developed the computational system cSAF - consultation for Specific Absorbed Fractions (cFAE from Portuguese acronym) - which furnishes several 'look-up' facilities for the research user. The dialogue interface with the operator was planned following current practices in the utilization of event-oriented languages. This interface permits the user to navigate by means of the reference models, choose the source organ, the energy desired, and receive an answer through an efficient and intuitive dialogue. The system furnishes, in addition to the data referring to the Brazilian woman, data referring to the model of Snyder and to the model of the Brazilian man. The system makes available not only individual data to the SAFs of the three models, but also a comparison among them. (author)

Hidden costs: A Study of the Characteristics of the Articles Published in Brazilian Accounting Journals

2016-09-01

Full Text Available This study analyzes the characteristics of the articles published in Brazilian journals of accounting from 2000-2015 with respect to the topic of hidden costs. Hidden costs occur during an organization's management process, although they are not routinely perceived. They have their origin in internal or external dysfunctions of the organization and represent lapses and missed earnings. The nature of the study is quantitative and bibliometric. The sample was composed of 16 articles on the subject of hidden costs published in Brazilian accounting journals listed by the National Association of Graduate Programs in Accounting (ANPCONT during the period under analysis. Principal findings indicate that only 7 of the 37 journals analyzed published on the subject, for a total of 16 articles . This represents only 0.22% of all articles published in the journals analyzed. It is further noted that only 2 of the 16 articles were published in journals having a Qualis rating higher than B2. Forty-eight (48 different authors participated in the preparation of these studies, with only one author participating in more than one article. With respect to the specific issues addressed, environmental costs are noteworthy, present in 4 of the 16 articles analyzed. The contribution of this study is the identification of the lack of academic development on the subject, given the low number of articles published and the predominance of exploratory research (found in 7 of the studies analyzed.

On the Effects of Non-Tariff Measures on Brazilian Exports

Directory of Open Access Journals (Sweden)

LUCAS P. DO C. FERRAZ

Full Text Available This article estimates the effects of TBT/SPS measures on Brazilian exports, based on the recent literature of gravity models. A Heckman selection model - theoretically grounded on the seminal Melitz model of heterogeneous firms - highlights the role played by zero trade flows as well as firm heterogeneity for estimations using gravity equations, two factors usually omitted in standard specifications. We show that both extensive and intensive margins of Brazilian exports are, on average, negatively affected by pre-existing TBT and SPS measures. Moreover, we contribute to the empirical literature by providing comprehensive evidence of the sectoral effects of such measures over domestic exports. We find that TBT/SPS measures - though predominantly harmful - can foster exports in several sectors of the Brazilian economy.

Topic theory and Brazilian musicality: Considerations on rhetoricity in music

Directory of Open Access Journals (Sweden)

Acácio T. C. Piedade

2013-02-01

Full Text Available This article presents an application of the topic theory to the analyses of Brazilian music. It starts with a reflection on the concepts of musicality, friction of musicalities in Brazilian jazz, and the fusion of musicalities that emerges from the invention of tradition. The discussion follows with the question of the adaptability of topic theory to national musics. Then, some musical examples are used in order to present some of the universes of topics of Brazilian music. In this article I argue that the concept of rhetoricity brings good results to the study of musical signification, and that the theory of topics is useful for other contexts than classical music, being an interesting route to the investigation of sociocultural connections in musicalities.

The quest for recognition: Brazilian immigrants in the United States.

Science.gov (United States)

Zubaran, Carlos

2008-12-01

'Hispanic' and 'Latino' are imprecise umbrella terms often used in the United States to designate nationals from Central and South America. The labelling of Brazilians in this manner generates inaccurate demographic information, including a significant undercount of the migrant population. Research data indicates that Brazilians object to being designated Hispanics, since Brazilians speak Portuguese and have no Spanish heritage. The labelling of ethnic groups has been criticized as a stereotypical and racist system, which primarily responds to non-scientific demands. This commentary appeals for reform in the way researchers and institutions refer to minority citizens as well as for continued research to investigate racism and ethnic prejudice. The development of new approaches and methodologies to examine social networks, migration and the geographic concentration of poverty is advocated.

The proximity of the Paralympic Games Rio 2016 opens the discussion about the possibility of building a career in Paralympic sport. This study aims to present the characteristics and challenges present in the sporting career of the Brazilian Paralympic athlete. The study was structured under three main guiding topics: the different moments of Paralympic Sport, the career characteristics of paralympians and the consequences of sports results for their careers. Currently, Paralympic sports has its focus on high performance, as the constant necessity for good results is an ever present reality. The characteristics and challenges of sporting careers reveal the current situation for Brazilian Paralympic sports in all of its stages (pre-transition, transition and post-transition). Upon reflecting on the career of the Brazilian paralympic athlete a debate opens up concerning future perspectives and particularly on an understanding of the existing challenges for consolidation. Structural problems such as venues for training, lack of awareness on the part of the private sector and the non-renewal of human resources, seem to be the main obstacles for the consolidation of paralympic careers in Brazil.

A descriptive survey was performed in order to assess the statistical content and quality of Brazilian and international dental journals, and compare their evolution throughout the last decades. The authors identified the reporting and accuracy of statistical techniques in 1000 papers published from 1970 to 2000 in seven dental journals: three Brazilian (Brazilian Dental Journal, Revista de Odontologia da Universidade de Sao Paulo and Revista de Odontologia da UNESP) and four international journals (Journal of the American Dental Association, Journal of Dental Research, Caries Research and Journal of Periodontology). Papers were divided into two time periods: from 1970 to 1989, and from 1990 to 2000. A slight increase in the number of articles that presented some form of statistical technique was noticed for Brazilian journals (from 61.0 to 66.7%), whereas for international journals, a significant increase was observed (65.8 to 92.6%). In addition, a decrease in the number of statistical errors was verified. The most commonly used statistical tests as well as the most frequent errors found in dental journals were assessed. Hopefully, this investigation will encourage dental educators to better plan the teaching of biostatistics, and to improve the statistical quality of submitted manuscripts.

Rocha-e-Silva, Mauricio

2010-06-01

This review of original reports on metabolic and infectious diseases that were recently published in Brazilian journals is designed to inform the readership of CLINICS about their content. I conducted a search in PubMed for original research articles (clinical or basic research) recently published (2008-2009) by Brazilian medical and biological periodicals. Papers on metabolic pathologies were retrieved by searching for appropriate keywords such as metabolic syndrome and obesity. Papers on infectious disease were obtained by entering 15 different keywords for the most commonly occurring pathologies. Review articles, editorials, letters to the editor, and case reports were manually excluded. Selected titles were then categorized into appropriate sub-categories. This search produced a total of 123 articles, which filtered down to 72 articles after eliminating editorials, review articles, letters to the Editor and case reports. Reviewed periodicals were Arquivos Brasileiros de Cardiologia, Arquivos Brasileiros de Endocrinologia e Metabologia, Brazilian Journal of Biological and Medical Research, Brazilian Journal of Infectious Diseases, Jornal de Pediatria, Jornal de Pneumologia, Revista da Associação Médica Brasileira, Revista da Escola de Enfermagem da Universidade de São Paulo, and São Paulo Medical Journal. The articles were then briefly summarized.

Full Text Available ABSTRACT OBJECTIVE To describe food and macronutrient intake profile and estimate the prevalence of inadequate micronutrient intake of Brazilian adolescents. METHODS Data from 71,791 adolescents aged from 12 to 17 years were evaluated in the 2013-2014 Brazilian Study of Cardiovascular Risks in Adolescents (ERICA. Food intake was estimated using 24-hour dietary recall (24-HDR. A second 24-HDR was collected in a subsample of the adolescents to estimate within-person variability and calculate the usual individual intake. The prevalence of food/food group intake reported by the adolescents was also estimated. For sodium, the prevalence of inadequate intake was estimated based on the Tolerable Upper Intake Level (UL. The Estimated Average Requirement (EAR method used as cutoff was applied to estimate the prevalence of inadequate nutrient intake. All the analyses were stratified according to sex, age group and Brazilian macro-regions. All statistical analyses accounted for the sample weight and the complex sampling design. RESULTS Rice, beans and other legume, juice and fruit drinks, breads and meat were the most consumed foods among the adolescents. The average energy intake ranged from 2,036 kcal (girls aged from 12 to 13 years to 2,582 kcal (boy aged from14 to 17 years. Saturated fat and free sugar intake were above the maximum limit recommended ( 50.0%. Sodium intake was above the UL for more than 80.0% of the adolescents. CONCLUSIONS The diets of Brazilian adolescents were characterized by the intake of traditional Brazilian food, such as rice and beans, as well as by high intake of sugar through sweetened beverages and processed foods. This food pattern was associated with an excessive intake of sodium, saturated fatty acids and free sugar.

A measurement evaluation program to support nuclear material control and accountability measurements in Brazilian laboratories

Dias, Fabio C.; Mason, Peter

2013-01-01

A measurement evaluation program (MEP) is one of a number of valuable tools that analytical chemists can use to ensure that the data produced in the laboratory are fit for their intended purpose and consistent with expected performance values at a given time. As such, participation in a MEP is an important indicator of the quality of analytical data, and is recognized as such by independent regulatory and/or accreditation bodies. With the intent to implement such a program in Brazil, in November 2012 the Nuclear Energy Commission of Brazil (CNEN), with support from the Department of Energy of the United States' (US-DOE International Safeguards and Engagement Program), decided to initiate a technical cooperation project aiming at organizing a Safeguards Measurement Evaluation Program (SMEP) for Brazilian facilities. The project, entitled Action Sheet 23, was formalized under the terms of the Agreement between the US-DOE and the CNEN concerning research and development in nuclear material control, accountancy, verification, physical protection, and advanced containment and surveillance technologies for International Safeguards Applications. The work, jointly performed by the CNEN's Safeguards Laboratory (LASAL) and the New Brunswick Laboratory (NBL), has the objective to strengthen the traceability of accountability measurements and ensure adequate quality of safeguards measurements for facilities within Brazil, utilizing test samples characterized and provided by NBL. Recommendations to participants included measurement frequency, number of results per sample and format for reporting results using ISO methods for calculating and expressing measurement uncertainties. In this paper, we discuss the main steps taken by CNEN and NBL aiming at implementing such a program and the expected results, in particular the impact of uncertainty estimation on the evaluation of performance of each participant laboratory. The program is considered by Brazilian safeguards authorities

Biotypology, regionalism, and the construction of a plural Brazilian bodily identity, 1930s.

Science.gov (United States)

Vimieiro-Gomes, Ana Carolina

2016-12-01

This article investigates regional biotypological studies and the construction of biological deterministic discourses about the Brazilian identity in the 1930s. Biotypological research was undertaken to determine the normal body type of the Brazilian man, using its peculiar classificatory lexicon. Studies into the bodily profile of specific regions, like the northeast and São Paulo state, featured in this research. In the context of the contemporary debates about race, miscegenation, and national identity, these investigations were geared towards biological determinism and the influence of the environment and social and cultural aspects on the bodily development of Brazilians. It is shown how regional biotypological studies echoed racial, normalizing, exclusive viewpoints and contributed to the construction of a miscegenated Brazilian bodily identity.

Bees are manufacturers of relevant economical products and have a pollinator role fundamental to ecosystems. Traditionally, studies focused on the genus Melipona have been mostly based on behavioral, and social organization and ecological aspects. Only recently the evolutionary history of this genus has been assessed using molecular markers, including mitochondrial genes. Even though these studies have shed light on the evolutionary history of the Melipona genus, a more accurate picture may emerge when full nuclear and mitochondrial genomes of Melipona species become available. Here we present the assembly, annotation, and characterization of a draft mitochondrial genome of the Brazilian stingless bee Melipona scutellaris using Melipona bicolor as a reference organism. Using Illumina MiSeq data, we achieved the annotation of all protein coding genes, as well as the genes for the two ribosomal subunits (16S and 12S) and transfer RNA genes as well. Using the COI sequence as a DNA barcode, we found that M. cramptoni is the closest species to M. scutellaris.

New Configuration of the Brazilian State: Liberty and Development in the Evolution of Government in Brazil

Maya Reyes-Ricon

2010-10-01

Full Text Available The recent events in the global economy have revitalized the debate about the size and functions of the State. The neoliberal discourse was put in check, reopening the discussions concerning Market Liberty and the importance of the State. Since the proclamation of the Republic, the Brazilian government has undergone numerous reforms, sometimes assuming a liberal, external market dependent orientation, while at other times assuming an authoritarian, developmental state-driven orientation. The aim of this article is to develop insights into the evolution of the governmental organization and reflect on the assumptions that lie behind the various reforms that have taken place since the beginning of the Republic. The theoretical framework is divided into three parts: Development and Liberty based on the perspectives of Friedrich Hayek and Amartya Sen; the role of the State and its impact on the economy and; the formats assumed by the Brazilian State throughout the history of the Republic. The latter part of the work returns to the theoretical framework, summarizing all that has been discussed in order to fulfil the aims of the study.

Evaluating fire danger in Brazilian biomes: present and future patterns

Science.gov (United States)

Silva, Patrícia; Bastos, Ana; DaCamara, Carlos; Libonati, Renata

2017-04-01

Climate change is expected to have a significant impact on fire occurrence and activity, particularly in Brazil, a region known to be fire-prone [1]. The Brazilian savanna, commonly referred to as cerrado, is a fire-adapted biome covering more than 20% of the country's total area. It presents the highest numbers of fire events, making it particularly susceptible to changes in climate. It is thus essential to understand the present fire regimes in Brazilian biomes, in order to better evaluate future patterns. The CPTEC/INPE, the Brazilian Center for Weather Forecasting and Climate Research at the Brazilian National Institute of Space Research developed a fire danger index based on the occurrence of hundreds of thousands of fire events in the main Brazilian biomes [2]: the Meteorological Fire Danger Index (MFDI). This index indicates the predisposition of vegetation to be burned on a given day, for given climate conditions preceding that day. It relies on daily values of air temperature, relative humidity, accumulated precipitation and vegetation cover. In this study we aim to access the capability of the MFDI to accurately replicate present fire conditions for different biomes, with a special focus on cerrado. To this end, we assess the link between the MFDI as calculated by three different reanalysis (ERA-Interim, NCEP/DOE Reanalysis 2 and MERRA-2) and the observed burned area. We further calculate the validated MFDI using a regional climate model, the RCA4 as forced by EC-Earth from CORDEX, to understand the ability of the model to characterize present fire danger. Finally, the need to calibrate the model to better characterize future fire danger was also evaluated. This work was developed within the framework of the Brazilian Fire-Land-Atmosphere System (BrFLAS) Project financed by the Portuguese and Brazilian science foundations, FCT and FAPESP (project references FAPESP/1389/2014 and 2014/20042-2).

Constitutional guarantees generate negative externalities for the brazilian health system

Directory of Open Access Journals (Sweden)

Sandra Mara Campos Alves

2016-12-01

Full Text Available The research was conducted in 27 Brazilian courts of law. We aimed to know the legal demands on health and the arguments made by the patient, the defense, and the judge in judicial hearings. For this, we used the method of case law research. The research unit was Brazilian judicial processes with the material object of health demands, decided between 2012 and 2013. The results showed reliance on constitutional arguments for both the request and the decision, while the defense was based on diverse and obsolete legal points. It was concluded that judges have decided questions about health using purely legal arguments and reproducing points made by the patient. The defense of the Brazilian health system is fragile due to the lack of an adequate legal rationale.

Asymmetric catalysis in Brazil: development and potential for advancement of Brazilian chemical industry

The preparation of enantiomerically pure or enriched substances is of fundamental importance to pharmaceutical, food, agrochemical, and cosmetics industries and involves a growing market of hundreds of billions of dollars. However, most chemical processes used for their production are not environmentally friendly because in most cases, stoichiometric amounts of chiral inductors are used and substantial waste is produced. In this context, asymmetric catalysis has emerged as an efficient tool for the synthesis of enantiomerically enriched compounds using chiral catalysts. More specifically, considering the current scenario in the Brazilian chemical industry, especially that of pharmaceuticals, the immediate prospect for the use of synthetic routes developed in Brazil in an enantioselective fashion or even the discovery of new drugs is practically null. Currently, the industrial production of drugs in Brazil is primarily focused on the production of generic drugs and is basically supported by imports of intermediates from China and India. In order to change this panorama and move forward toward the gradual incorporation of genuinely Brazilian synthetic routes, strong incentive policies, especially those related to continuous funding, will be needed. These incentives could be a breakthrough once we establish several research groups working in the area of organic synthesis and on the development and application of chiral organocatalysts and ligands in asymmetric catalysis, thus contributing to boost the development of the Brazilian chemical industry. Considering these circumstances, Brazil can benefit from this opportunity because we have a wide biodiversity and a large pool of natural resources that can be used as starting materials for the production of new chiral catalysts and are creating competence in asymmetric catalysis and related areas. This may decisively contribute to the growth of chemistry in our country. (author)

[Culture and health services: studying the participation of cultural traits of Brazilian society in the work process of primary healthcare services].

Science.gov (United States)

Pinto, Alessandra Maria Silva; Najar, Alberto Lopes

2011-11-01

The analysis of institutions is a widely researched area of health. The culture of organizations is understood as a symbolic possibility contained in a larger dimension, called "national culture". This premise justifies the incorporation of the social anthropological approach to the study of organizational culture. This study sought to establish the perceptions of employees of two primary healthcare services in Niterói, State of Rio de Janeiro, regarding commonly used social navigation strategies from the theory developed by Roberto DaMatta. The results showed the relational character associated with the stereotype of the Brazilian people manifested by conflicts arising from the existence of values based on the `individual' and the `person'. Among them are the distortions observed between discourse and practice, and the mobilization strategies of social navigation like "making do" - to establish a mediation between the person and the impersonal law. The organization of the services of the Niterói Family Medical Program apparently sets its employees the concrete challenge of balancing the egalitarian principle that underpins the Unified Health System (SSU) with the set of values upon which personal relations are based in Brazilian society.

Full Text Available The article analyzes how innovation generation occurs in subsidiaries of Brazilian multinational corporations acting in Portugal, specifically the role of customers in the process and the knowledge dynamics. A multiple case study approach was conducted in four subsidiaries operating in the Portuguese market for at least one year. Firms came from different activity sectors and sizes. Results identify permanent knowledge exchange flows between subsidiaries and headquarters, while the largest pour is from the later ones (in Brazil to their wings in Portugal. There are frequent innovations taking place in Portuguese subsidiaries. Such innovation processes are typically incremental in nature and occur predominantly in only some areas of the organization, where greater specialization and expertise are located. The most relevant results regard the existing strong interaction between subsidiaries and markets, especially with the larger customers that contribute with suggestions and are able to influence the new products creation in the subsidiaries.

A total of 2152 Actinobacteria strains were isolated from native Cerrado (Brazilian Savannah) soils located in Passos, Luminárias, and Arcos municipalities (Minas Gerais State, Brazil). The soils were characterised for chemical and microbiological analysis. The microbial analysis led to the identification of nine genera (Streptomyces, Arthrobacter, Rhodococcus, Amycolatopsis, Microbacterium, Frankia, Leifsonia, Nakamurella, and Kitasatospora) and 92 distinct species in both seasons studied (rainy and dry). The rainy season produced a high microbial population of all the aforementioned genera. The pH values of the soil samples from the Passos, Luminárias, and Arcos regions varied from 4.1 to 5.5. There were no significant differences in the concentrations of phosphorus, magnesium, and organic matter in the soils among the studied areas. Samples from the Arcos area contained large amounts of aluminium in the rainy season and both hydrogen and aluminium in the rainy and dry seasons. The Actinobacteria population seemed to be unaffected by the high levels of aluminium in the soil. Studies are being conducted to produce bioactive compounds from Actinobacteria fermentations on different substrates. The present data suggest that the number and diversity of Actinobacteria spp. in tropical soils represent a vast unexplored resource for the biotechnology of bioactives production.

Full Text Available This work aims to analyze the productive reality and propose a panorama for the Brazilian organic wine production, from the perspective of producers, representatives of the sector, market and consumers, thus seeking to highlight the market perspectives and adequacy to the consumers' aspirations. This production that aims to meet a growing demand for sustainable products, which include organic, biodynamic and natural foods, combined with the growing Brazilian tendency to consume better quality wines. To prosecute this study, an exploratory research was developed, interviewing twenty consumers, one intermediary, one representative of the sector and four wineries. The data were analyzed crossing the information collected with these actors and bring out key contents. The results show that production is not aligned with consumer demand that it is still necessary to review the information made available to consumers, in addition to making it clearer, other values could be aggregated to those products or better communicated. On this way, it is possible to conclude that an intermediate product between organic and conventional, which has sustainable practices in its production could meet the current demand, so that in the future it can produce an organic product that corresponds to the consumer's demand.

GONZALO R. ALVAREZ

Full Text Available ABSTRACT This article presents an analysis of Brazilian research on High Energy Physics (HEP indexed by Web of Science (WoS from 1983 to 2013. Scientometric indicators for output, collaboration and impact were used to characterize the field under study. The results show that the Brazilian articles account for 3% of total HEP research worldwide and that the sharp rise in the scientific activity between 2009 and 2013 may have resulted from the consolidation of graduate programs, the increase of the funding and of the international collaboration as well as the implementation of the Rede Nacional de Física de Altas Energias (RENAFAE in 2008. Our results also indicate that the collaboration patterns in terms of the authors, the institutions and the countries confirm the presence of Brazil in multinational Big Science experiments, which may also explain the prevalence of foreign citing documents (all types, emphasizing the international prestige and visibility of the output of Brazilian scientists. We concluded that the scientometric indicators suggested scientific maturity in the Brazilian HEP community due to its long history of experimental research.

Full Text Available Hepatitis C, a worldwide viral infection, is an important health problem in Brazil. The virus causes chronic infection, provoking B lymphocyte dysfunction, as represented by cryoglobulinemia, non-organ-specific autoantibody production, and non-Hodgkin's lymphoma. The aim of this research was to screen for the presence of antiphospholipid autoantibodies in 109 Brazilian hepatitis C virus carriers without clinical history of antiphospholipid syndrome. Forty healthy individuals were used as the control group. IgA, IgG, and IgM antibodies against cardiolipin and β2-glycoprotein I were measured with an enzyme-linked immunosorbent assay, using a cut-off point of either 20 UPL or 20 SBU. While 24 (22.0% hepatitis C carriers had moderate titers of IgM anticardiolipin antibodies (median, 22.5 MPL; 95%CI: 21.5-25.4 MPL, only three carriers (<3% had IgG anticardiolipin antibodies (median, 23 GPL; 95%CI: 20.5-25.5 GPL. Furthermore, IgA anticardiolipin antibodies were not detected in these individuals. Male gender and IgM anticardiolipin seropositivity were associated in the hepatitis C group (P = 0.0004. IgA anti-β2-glycoprotein-I antibodies were detected in 29 of 109 (27.0% hepatitis C carriers (median, 41 SAU; 95%CI: 52.7-103.9 SAU. Twenty patients (18.0% had IgM anti-β2-glycoprotein I antibodies (median, 27.6 SMU; 95%CI: 23.3-70.3 SMU, while two patients had IgG antibodies against this protein (titers, 33 and 78 SGU. Antiphospholipid antibodies were detected in only one healthy individual, who was seropositive for IgM anticardiolipin. We concluded that Brazilian individuals chronically infected with hepatitis C virus present a significant production of antiphospholipid antibodies, mainly IgA anti-β2-glycoprotein I antibodies, which are not associated with clinical manifestations of antiphospholipid syndrome.

The primary goal of the BRAVO project is to generate investment in information technology, with particular emphasis on datamining and statistical analysis. From a scientific standpoint, the participants assembled to date are engaged in several scientific projects in various fields of cosmology, astrophysics, and data analysis, with significant contributions from international partners. These scientists conduct research on clusters of galaxies, small groups of galaxies, elliptical galaxies, population synthesis, N-body simulations, and a variety of studies in stellar astrophysics. One of the main aspects of this project is the incorporation of these disparate areas of astrophysical research within the context of the coherent development of database technology.Observational cosmology is one of the branches of science experiencing the largest growth in the past few decades. large photometric and spectroscopic surveys have been carried out in both hemispheres. As a result, an extraordinary amount of data in all portions of the electromagnetic spectrum exists, but without standard techniques for storage and distribution. This project will utilize several specific astronomical databases, created to store data generated by several instruments (including SOAR, Gemini, BDA, etc), uniting them within a common framework and with standard interfaces. We are inviting members of the entire Brazilian astronomical community to partake in this effort. This will certainly impact both education and outreach efforts, as well as the future development of astrophysical research. Finally, this project will provide a constant investment in human resources. First, it will do so by stimulating ongoing short technical visits to Johns Hopkins University and Caltech. These will allow us to bring software technology and expertise in datamining back to Brazil. Second, we will organize the Summer School on Software Technology in Astrophysics, which will be designed to ensure that the Brazilian

Full Text Available Building Risk-Neutral Density (RND from options data is one useful way for extracting market expectations about a financial variable. For a sample of IDI (Brazilian Interbank Deposit Rate Index options from 1998 to 2009, this paper estimates the option-implied Risk-Neutral Densities for the Brazilian short rate using three methods: Shimko, Mixture of Two Log-Normals and Generalized Beta of Second Kind. Our in-sample goodness-of-fit evaluation shows that the Mixture of Log-Normals method provides better fitting to option’s data than the other two methods. The shape of log-normal distributions seems to fit well to the mean-reversal dynamics of Brazilian interest rates. We have also calculated the RND implied Skewness, showing how it could have provided market early-warning signals of the monetary policy outcomes in 2002 and 2003. Overall, Risk-Neutral Densities implied on IDI options showed to be a useful tool for extracting market expectations about future outcomes of the monetary policy.

This study aimed to analyze the proximate composition of seeds from some non-conventional Brazilian fruits, as well as to evaluate the antioxidant activity through DPPH(•) free radical and to quantify the total phenolic compounds. To obtain the extracts, dried and crushed seeds were extracted with ethanol for 30 min, in a ratio of 1:3 (seeds:ethyl alcohol), under continuous agitation, at room temperature. Then, the mixtures were filtered and the supernatants were subjected to rotary evaporator under pressure reduced to 40 °C. The results report that the seeds of non-conventional fruits are remarkable sources of lipids, and the extraction of oil from these seeds could be an alternative for the commercial utilization of waste. They also presented significant percentages of protein and carbohydrates. Ethanol extracts of seeds from non-conventional Brazilian fruits showed relevant antioxidant activity and high amount of phenolic compounds. Therefore Brazilian non-conventional fruits can be used as functional food products or feed.

Full Text Available Vossoroca is a reservoir in the Brazilian state of Paraná. Although it is located near big cities and can be used as a human water supply, it has remained unstudied. Concentrations of toxic metals and arsenic in sediments, water, liver, gills, and muscle of Geophagus brasiliensis from the reservoir were analyzed using atomic absorption spectrometry. Histological analyses were performed on the gills and the livers using scanning electron microscopy and light microscopy, respectively. The results showed that Vossoroca sediments were moderately polluted by copper, chromium, nickel and arsenic. Cadmium was above legal limits in the water. Histopathological assessment revealed epithelial alterations in the secondary lamella to be the most common abnormality observed in the gills and necrosis, melanomacrophage centers in the livers. In conclusion, although the reservoir is located in an Environmental Protection Area, it is negatively affected by human activity. Further, Geophagus brasiliensis was a suitable bioindicator for metal pollution studies.

Full Text Available INTRODUCTION: The objective of this study was to identify the patterns of dental variables of adolescent Japanese-Brazilian descents with normal occlusion, and also to compare them with a similar Caucasian and Mongoloid sample. METHODS: Lateral cephalometric radiographs were used to compare the groups: Caucasian (n = 40, Japanese-Brazilian (n = 32 and Mongoloid (n = 33. The statistical tests used were one-way ANOVA and ANCOVA. The cephalometric measurements used followed the analyses of Steiner, Tweed and McNamara Jr. RESULTS: Statistical differences (P < 0.05 indicated a smaller interincisal angle and overbite for the Japanese-Brazilian sample, when compared to the Caucasian sample, although with similar values to the Mongoloid group. CONCLUSION: The dental patterns found for the Japanese-Brazilian descents were, in general, more similar to those of the Mongoloid sample.

Luiz Kennedy Cruz Machado

2016-01-01

Full Text Available The economic changes in recent years have made the dynamics of the Brazilian market more complex, which directly impacts the administration of large organizations, particularly in management tasks, such as decisions concerning the definition of the capital structure. The literature in this theoretical field is polarized in two seminal works: the first, by Durand (1952, 1959, discusses the existence of an optimal capital structure that maximizes the value of the firm; and, at the other end, the work by Modigliani and Miller (1958, 1963 considers that it is irrelevant how firms are financed. In this sense, the objective was to verify the effective interference of the capital structure in the performance of Brazilian firms listed on BM&FBOVESPA. The sample consisted of cross-sectional data that were selected from the most recent balance sheets of all companies listed on BM&FBOVESPA, available in the Economática® database. The techniques used were the analysis of variance (ANOVA and discriminant analysis. Among the indicators used, it was observed that only general liquidity, the degree of immobilization, Tobin’s Q, and the opportunity for growth were significant at 1%. The results indicate that the capital structure is not directly related to the performance of Brazilian companies listed on BM&FBOVESPA. In the meantime, the results point to the consolidation of the financial theories expounded by Modigliani and Miller (1958, 1963, as opposed to the traditionalist current started in Durand’s studies (1952.

Full Text Available This research aims to present the Fair Information Principles in the privacy policies of the websites of major Brazilian companies (according to the 2014 Forbes Magazine list. The check and analysis were supported by a checklist compiled from documents issued by the Federal Trade Commission and the Organization for Economic Co-operation and development. The study selected fourteen companies from a universe of twenty-five, considering the immediacy criterion of access to the privacy policy on their websites. The security (safeguards principle is the most widespread foundation at the privacy policies of the companies selected (existing in eight of the fourteen analyzed policies; and the principle of responsibility receives less adhesion due to the fact that it is not covered in any of the examined online privacy policies. The Sabesp Company presents the most complete privacy policy, considering the compliance with the Fair Information Principles when compared to the others perused, while WEG does not present any of the principles identified in the documental survey. As for e-commerce, the number of companies that assume some of the Principles is further reduced. For the selected universe the adherence to the Fair information Principles is still incipient, althought its use is not mandatory. An open discussion of the proposed Brazilian law about personal data protection should play an important role in creating further guidance on the subject. Additional studies in this subject should involve the perception of users, as well as a cutout of companies which target e-commerce, considering that an effective alignment with these principles and other guidelines are required in order to protect the user’s privacy and personal data in the web environment.

To determine the influence of reproductive history on the prevalence of obesity in Brazilian women and the possible modifying effect of socioeconomic variables on the association between parity and excess weight. A retrospective analysis of complex sample data collected as part of the 2006 Brazilian National Survey on Demography and Health, which included a group representative of women of childbearing age in Brazil was conducted. The study included 11 961 women aged 20 to 49 years. The association between the study factor (parity) and the outcome of interest (obesity) was tested using logistic regression analysis. The adjusted effect of parity on obesity was assessed in a multiple regression model containing control variables: age, family purchasing power, as defined by the Brazilian Association of Research Enterprises (ABEP), schooling, and health care. Significance level was set at below 0.05. The prevalence of obesity in the study population was 18.6%. The effect of parity on obesity was significant (P for trend parity and age. Family purchase power had a significant odds ratio for obesity only in the unadjusted analysis. In the adjusted model, this variable did not explain obesity. The present findings suggest that parity has an influence on obesity in Brazilian women of childbearing age, with higher prevalence in women vs. without children.

The importance and protection of mangrove ecosystems has been recognized in Brazilian Federal law since 1965. Being protected in law, however, has not always guaranteed their protection in practice. Mangroves are found in coastal and estuarine locations, which are prime real estate for the growth of cities, ports and other economic activities important for Brazilian development. In this mini-review we introduce what mangroves are and why they are so important. We give a brief overview of the microbial diversity found in mangrove sediments and then focus on diversity studies from Brazilian mangroves. We highlight the breadth and depth of knowledge about mangrove microbial communities gained from studying Brazilian mangroves. We report on the exciting findings of molecular microbial ecology methods that have been very successfully applied to study bacterial communities. We note that there have been fewer studies that focus on fungal communities and that fungal diversity studies deserve more attention. The review ends with a look at how a combination of new molecular biology methods and isolation studies are being developed to monitor and conserve mangrove ecosystems and their associated microbial communities. These recent studies are having a global impact and we hope they will help to protect and re-establish mangrove ecosystems. PMID:24031949

From solid to liquid: assessing the release of organic matter into soil solution in response to land-use conversion in Brazilian Oxisols

Recent advances in freshwater research indicate that roughly double the quantity of carbon is exported from soils to streams and rivers than was previously estimated, and that the age of carbon exported from major rivers globally increases with greater human disturbance in the watershed. This implies that human land-use can release old, previously mineral-associated C into solution with subsequent export to groundwater and ultimately freshwater systems where terrestrial organic matter is either mineralized to CO2, stored in aquatic sediments, or exported to the ocean. Consequently, it is important to understand the mechanisms that cause the release of SOM that is mineral-bound into solution in response to human disturbance and land-use change. Research methods have been established to examine both the fast turnover, dissolved pool of soil organic matter (SOM), as well as the slow turnover, mineral-associated pool. However, to better characterize the response of the total SOM pool to disturbance, it is necessary to understand the interactions between these functional pools by examining them both simultaneously. This study seeks to examine the interaction between dissolved organic matter (DOM) and bulk SOM throughout the soil profile in response to conversion of Brazilian Cerrado (savannah forest) to Eucalyptus plantation forest on the same soil type. The water-extractable organic matter was obtained from soil samples down to 150 cm, characterized using fluorescence and NMR spectroscopy, and carbon-dated. Simultaneously, bulk mineral soil samples were analyzed for microbial biomass, carbon content and age, and characterized using Fourier Transform Infrared Spectroscopy. SOM spectra were obtained by washing subsamples with sodium hypochlorite and subtracting the subsequent mineral matrix spectra from bulk soil spectra. Preliminary results show that microbial biomass decreases much more quickly with depth than DOM, suggesting that C released into solution from deeper

Ancestry informative markers in Amerindians from Brazilian Amazon.

Ancestry informative markers (AIMs) are genetic loci with large frequency differences between the major ethnic groups and are very useful in admixture estimation. However, their frequencies are poorly known within South American indigenous populations, making it difficult to use them in admixture studies with Latin American populations, such as the trihybrid Brazilian population. To minimize this problem, the frequencies of the AIMs FY-null, RB2300, LPL, AT3-I/D, Sb19.3, APO, and PV92 were determined via PCR and PCR-RFLP in four tribes from Brazilian Amazon (Tikúna, Kashinawa, Baníwa, and Kanamarí), to evaluate their potential for discriminating indigenous populations from Europeans and Africans, as well as discriminating each tribe from the others. Although capable of differentiating tribes, as evidenced by the exact test of population differentiation, a neighbor-joining tree suggests that the AIMs are useless in obtaining reliable reconstructions of the biological relationships and evolutionary history that characterize the villages and tribes studied. The mean allele frequencies from these AIMs were very similar to those observed for North American natives. They discriminated Amerindians from Africans, but not from Europeans. On the other hand, the neighbor-joining dendrogram separated Africans and Europeans from Amerindians with a high statistical support (bootstrap = 0.989). The relatively low diversity (G(ST) = 0.042) among North American natives and Amerindians from Brazilian Amazon agrees with the lack of intra-ethnic variation previously reported for these markers. Despite genetic drift effects, the mean allelic frequencies herein presented could be used as Amerindian parental frequencies in admixture estimates in urban Brazilian populations.

Public health policy and the building up of a Brazilian medical identity.

Science.gov (United States)

de Castro-Santos, L A

2005-12-01

Since George Herbert Mead studied "the social self" and the interactionists went further in distinguishing "images of self", a lecture on the building up of a Brazilian medical identity should try to focus on the patterns of self-images, presented images, and aspired-to images among the Brazilian medical elites during the First Republic (1889-1930). In no other period of Brazilian history were those "images" of professional identity so close--in contrast, later periods of Brazilian history witnessed an almost permanent "collision" or the clashing of such images among public health specialists. Oswaldo Cruz, Carlos Chagas, Artur Neiva and Belisário Pena are perhaps the best examples of successful careers as "sanitarians" (to recall John Duffy's historical work on luminaries before and after the "New Public Health" in the United States), and as important political actors during Brazil's First Republic. In light of the prominent political, policy-oriented, and scientific roles public health professionals played in Brazil, it is interesting to suggest that in large part such prominence resulted from the symbolic impact of the ideologies of sanitary reform on the political agenda of that period of Brazilian history. Where many studies look for personal rivalries and disputes around Chagas and Neiva as public figures, we may also see the importance of finding identity-building processes among public health specialists as an integrated group (e.g., trying to appear as "significant others" for the new generations of medical graduates in the country), regardless of existing rivalries. Cruz and Chagas, especially, were names with great impact in the Brazilian press (pro and con), a circumstance made possible largely by their easy and direct access to the Brazilian presidents Rodrigues Alves and Epitácio Pessoa, and, most clearly, by public health being one of Brazil's political priorities to find a place among the "civilized nations" of the world.

We studied the similarities and differences between Brazilian Spiritistic mediums and North American dissociative identity disorder (DID) patients. Twenty-four mediums selected among different Spiritistic organizations in São Paulo, Brazil, were interviewed using the Dissociative Disorder Interview Schedule, and their responses were compared with those of DID patients described in the literature. The results from Spiritistic mediums were similar to published data on DID patients only with respect to female prevalence and high frequency of Schneiderian first-rank symptoms. As compared with individuals with DID, the mediums differed in having better social adjustment, lower prevalence of mental disorders, lower use of mental health services, no use of antipsychotics, and lower prevalence of histories of physical or sexual childhood abuse, sleepwalking, secondary features of DID, and symptoms of borderline personality. Thus, mediumship differed from DID in having better mental health and social adjustment, and a different clinical profile.

Male recombination in Brazilian populations of Drosophila ananassae.

With few exceptions, spontaneous crossing over does not normally occur in male Drosophila. Drosophila ananassae males show considerable amounts of crossing over. In wild males of D. ananassae from Asian (2008) and Brazilian populations (1986 and 2007) variable frequencies of meiotic crossing over, estimated from chiasmata counts, suggested the existence of factors controlling male crossing over in these populations. To corroborate for such prediction, we present data on spontaneous recombination in F1 males of D. ananassae heterozygous for chromosomes of the same Brazilian populations (1986) and marker chromosomes using three testers stocks. Mean recombination value was low, although high variability existed between individual frequencies. Recombination frequencies between lines in each tester stock were not significantly different, excepting when the 3ple-px and 3ple-cy testers were compared (p recombination in chromosomes 2 and 3 in F1 males tested with e(65) se; bri ru was not related, suggesting they are under independent genetic control. Our data are consistent with proposed genetic factors controlling male crossing over in the tester stocks and to the presence of enhancers and suppressors of male crossing over segregating in the Brazilian populations (1986).

Epidemiology and treatment of psoriasis: a Brazilian perspective.

Duarte, Gleison V; Porto-Silva, Larissa; de Oliveira, Maria de Fátima Paim

2015-01-01

Psoriasis is a chronic immune-mediated systemic disease that is influenced by genetic and environmental factors, is associated with comorbidities, and has a negative impact on the quality of life of affected individuals. The prevalence of psoriasis varies among different ethnic groups, but this topic has not been studied in Brazil to date. In this review, we evaluate the epidemiology and treatment of psoriasis from a Brazilian perspective. We focused on studies that involved Brazilian subjects. The prevalence of psoriasis in Brazil is estimated to be 2.5%, but no population study has been performed previously. Environmental factors, such as tropical climate, in association with genetic factors, such as miscegenation, may exert a beneficial impact on the course and frequency of psoriasis in Brazil. A number of studies have advanced our understanding of the cardiovascular, ophthalmic, and oral comorbidities that are associated with psoriasis. Concerns about biological therapy, such as endemic leprosy, human T-cell lymphotropic virus (HTLV), and tuberculosis infections, are discussed. The nonavailability of treatment options for psoriasis in the public health system contradicts the Brazilian Society of Dermatology guidelines, stimulating the judicialization of access to medicines in psoriasis care.

Full Text Available Objective : To develop a consensus for translation of the most relevant terms used in the study of Adult Spinal Deformity, from their original languages into Brazilian Portuguese. Methods : A panel of 12 experts in spine surgery from the five Brazilian regions was constituted. To obtain the standardization of terminology, the Delphi method with an electronic questionnaire was administered to participants about their opinion on the translation of 13 relevant terms chosen by literature review. Each term was considered standard when there was consensus, that is, concordance higher than 80% among participants as to the suggestion to be adopted, and then on the acceptance of the term and its abbreviation in Portuguese. Results : Initially there was consensus (over 80% concordance on the translation of seven terms in the electronic questionnaire. The other six terms that have not reached consensus were discussed at a meeting among the participants, relying on the opinion of a specialized professional in simultaneous translation of orthopedic terms in Portuguese and other professional majored in Portuguese language. It was decided how these terms should be translated and there was a consensus among all participants regarding their acceptance. Finally, there was consensus among the participants, who agreed with the translation and abbreviation of the 13 propose terms, defining its standardization for Brazilian Portuguese. Conclusion : We present a standard terminology used in the study of Adult Spinal Deformity through consensus among experts, seeking uniformity in the use of these terms in Brazilian Portuguese.

We study the Brazilian Popular Music in a network perspective. We call the Brazilian Popular Music Network, BPMN, the graph where the vertices are the song writers and the links are determined by the existence of at least a common singer. The linking degree distribution of such graph shows power law and exponential regions. The exponent of the power law is compatible with the values obtained by the evolving network algorithms seen in the literature. The average path length of the BPMN is similar to the correspondent random graph, its clustering coefficient, however, is significantly larger. These results indicate that the BPMN forms a small-world network.

The Brazilian external individual monitoring scenario

2015-01-01

In order to improve radiation protection it is necessary to have knowledge of the occupational radiation dose levels in all radiation facilities. This information comes from individual monitoring services, which are responsible for measuring and providing information about workers' radiation exposure. In 1981, the Comissao Nacional de Energia Nuclear (CNEN) of Brazil starts to develop a comprehensive system for regulation and storage of occupational radiation dose. This paper starts with an overview of the evolution of the Brazilian authorization and data storage system for external individual monitoring. It starts with a rule for authorization of all Brazilian photon individual monitoring services and the obligation for them to send the measured dose to CNEN. Up to now there is no regulation for neutron individual monitoring. The aim of this paper is to present the current scenario of the Brazilian external monitoring system, reinforcing its importance and remaining problems. The number of monitored workers greatly increases every year, having surpassed 150,000 people monitored. The stored data show that the mean annual occupational external dose is decreasing from 2.4 mSv in 1987 to about 0.6 mSv, in 2012, but there is still some not realistic very high dose measured (higher than 100 mSv), without investigation. About 80% of the annual dose values are lower than the monthly register level. As expected, the higher real photon doses are found in Nuclear Medicine, Industrial Radiology and Interventional Radiology. All recorded annual neutron dose values are lower than 20 mSv. (author)

Full Text Available The Sport Motivation Scale was firstly developed in French and later translated into English and validated by Pelletier et al. (1995. It is based on the principles of self-determination theory. The present study translated the English version into Portuguese to access and validate it with Brazilian athletes using a sample of 419 athletes (127 women and 292 men from ten sports. The Brazilian version of the scale showed satisfactory levels of internal consistency and temporal stability over a four-week period. The results of a confirmatory factor analysis partially supported the seven-factor structure. Finally, gender differences were found in all subscales. Taken together, these findings support the use of the Brazilian version of the scale for the assessment of motivation in sport.

A National Identity Management Strategy to Enhance the Brazilian Electronic Government

Directory of Open Access Journals (Sweden)

José Alberto Sousa Torres

2017-12-01

Full Text Available Amongst the several problems with the Brazilian e-government services (e-Gov, many of them are related to the fact that Brazil does not have a National Strategy for Digital Identity Management (IdM. To design a  national strategy, it is crucial to analyze the solutions adopted in other countries and take into account Brazilian characteristics, such as its area, population, digital inclusion index, socio-political and economic profile, the current national identity registration system and the fraud rate. In this context, this paper aims to propose a national strategy for IdM for the Brazilian e-Gov program. This strategy was built upon by a literature review of the experiences of European countries and, mainly, the peculiarities inherent to Brazil.

Anthropophagy: a singular concept to understand Brazilian culture and psychology as specific knowledge.

Science.gov (United States)

Ferreira, Arthur Arruda Leal

2015-11-01

The aim of this work is to present the singularity of the concept of anthropophagy in Brazilian culture. This article examines its use in the Modernist Movement of the 1920s and explores the possibilities it creates for thinking about Brazilian culture in nonidentitarian terms. We then use the concept of anthropophagy in a broader, practical sense to understand psychology as a kind of anthropophagical knowledge. We do so because in many ways the discipline of psychology is similar to Brazilian culture in its plurality and complexity. (c) 2015 APA, all rights reserved).

Brazilian low and intermediate level radioactive waste disposal and environmental conservation areas

International Nuclear Information System (INIS)

Uemura, George; Cuccia, Valeria

2013-01-01

Low and intermediate level radioactive waste should be disposed off in proper disposal facilities. These facilities must include unoccupied areas as protection barriers, also called buffer zone. Besides that, Brazilian environmental laws require that certain enterprises must preserve part of their area for environmental conservation. The future Brazilian low and intermediate level waste repository (RBMN) might be classified as such enterprise. This paper presents and discusses the main Brazilian legal framework concerning different types of conservation areas that are allowed and which of them could be applied to the buffer zones of RBMN. The possibility of creating a plant repository in the buffer zone is also discussed. (author)

Brazilian Tensile Strength of Anisotropic Rocks: Review and New Insights

Directory of Open Access Journals (Sweden)

Tianshou Ma

2018-01-01

Full Text Available Strength anisotropy is one of the most distinct features of anisotropic rocks, and it also normally reveals strong anisotropy in Brazilian test Strength (“BtS”. Theoretical research on the “BtS” of anisotropic rocks is seldom performed, and in particular some significant factors, such as the anisotropic tensile strength of anisotropic rocks, the initial Brazilian disc fracture points, and the stress distribution on the Brazilian disc, are often ignored. The aim of the present paper is to review the state of the art in the experimental studies on the “BtS” of anisotropic rocks since the pioneering work was introduced in 1964, and to propose a novel theoretical method to underpin the failure mechanisms and predict the “BtS” of anisotropic rocks under Brazilian test conditions. The experimental data of Longmaxi Shale-I and Jixi Coal were utilized to verify the proposed method. The results show the predicted “BtS” results show strong agreement with experimental data, the maximum error is only ~6.55% for Longmaxi Shale-I and ~7.50% for Jixi Coal, and the simulated failure patterns of the Longmaxi Shale-I are also consistent with the test results. For the Longmaxi Shale-I, the Brazilian disc experiences tensile failure of the intact rock when 0° ≤ βw ≤ 24°, shear failure along the weakness planes when 24° ≤ βw ≤ 76°, and tensile failure along the weakness planes when 76° ≤ βw ≤ 90°. For the Jixi Coal, the Brazilian disc experiences tensile failure when 0° ≤ βw ≤ 23° or 76° ≤ βw ≤ 90°, shear failure along the butt cleats when 23° ≤ βw ≤ 32°, and shear failure along the face cleats when 32° ≤ βw ≤ 76°. The proposed method can not only be used to predict the “BtS” and underpin the failure mechanisms of anisotropic rocks containing a single group of weakness planes, but can also be generalized for fractured rocks containing multi-groups of weakness planes.

Evidence of the Association Between Psychology and Tissue and Organ Transplantation in Brazil.

Silva, J D A; Ariente, L C; Roza, B A; Mucci, S

2016-09-01

The addition of psychologists to organ transplant teams is still new in Brazil. In seeking the efficient performance of this professional, the knowledge of the scientific production and the development of research in the area is fundamental. In this sense, this study aims to survey the Brazilian scientific research that has investigated the psychologic aspects involved in tissue and organ transplantation. A literature narrative review was performed with the use of the "Transplante AND Psicologia" descriptors in the Biblioteca Virtual em Saúde and the CAPES Journal Portal. Fifty-three articles were found, of which 22 met the inclusion criteria: publications dating from 2000 to 2014 and the main topic of interest of the studies being quality of life, followed by organ donation. The instruments used most frequently were interviews developed by the researchers and the SF-36 Quality of Life Questionnaire. Recent Brazilian studies on the association between psychology and transplantation are still scarce, possibly because of the recent addition of psychologists to transplantation teams. Therefore, it is suggested that more scientific research is made in the area and that the objects of study are more varied, to ensure adequacy of the psychologist to meet the specific demands of organ and tissue transplantation process.

The present study considers the production of knowledge and the interactions in the environment of research and their relationships in the system of caring in nursing and health. To elaborate a theoretical model of the organization of the practices used for caring, based on the experiences made by the research groups of administration and management in nursing, in Brazil. The study is based on grounded theory. Twelve leaders of research groups, working as professors in public universities in the south and the south-east of Brazil, distributed in sample groups, were interviewed. The core phenomenon 'research groups of administration and management in nursing: arrangements and interactions in the system of caring in nursing' was derived from the categories: conceptual bases and contexts of the research groups; experiencing interactions in the research groups; functionality of the research groups; and outputs of the research groups. The research groups are integrated in the system of caring in nursing. The activities of the Brazilian administration and management in nursing research groups are process oriented and in a process of constant renovation, socially relevant, operate in a complex scenario and contribute to the advancement of the organizations of the system of caring in nursing through strengthening the connection among academia, service and community. © 2011 The Authors.

Full Text Available In this article, we analyze the main non-wood forest products from Brazilian savanna. We studied the behavior and the growth rates of production and prices of almond of babaçu, oil of copaiba, fiber of buriti, leaf of jaborandi, bark of barbatimão, bark of angico, fruit of mangaba, almonds of pequi, from 1982 to 2005. All the products exhibited decreasing production, with exception of the oil of copaiba and almonds of pequi, which showed positive growth rates: 12.9% and 8.5%, respectively. The analysis of prices for most products was not significant, except for barks of barbatimão and angico, and almonds of pequi, which showed positive trends: 10.9%, 6.7%, and 4.6%, respectively. We believe that results were not significant due to the severe variations of the Brazilian currency in the period. We conclude that pequi is the main product from savanna and that oil of copaiba has the biggest increase in the production because most of the production comes from the whole Brazilian Amazon region.

To estimate the coverage of the reporting of cases of HIV-infected pregnant women, to estimate the increase in the coverage of the reporting with the routine search of data in other Brazilian health information systems, and to identify missed opportunities for identification of HIV-infected pregnant women in Brazilian maternity hospitals. This is a descriptive study on the linkage of Brazilian databases with primary data from the "Nascer no Brasil" study and secondary database collection from national health information systems. The "Nascer no Brasil" is a national-based study carried out in 2011-2012 with 23,894 pregnant women, which identified HIV-infected pregnant women using prenatal and medical records. We searched for cases of HIV-infected pregnant women identified in the "Nascer no Brasil" study in the Information System of Notifiable Diseases, the Control System for Laboratory Tests of the National CD4+/CD8+ Lymphocyte Count and HIV Viral Load Network, and the Logistics Control System for Medications. We used the OpenRecLink software for the linkage of databases. We estimated the notification coverage, with the respective confidence interval, of the evaluated Brazilian health information systems. We estimated the coverage of the reporting of HIV-infected pregnant women in the Information System of Notifiable Diseases as 57.1% (95%CI 42.9-70.2), and we located 89.3% of the HIV-infected pregnant women (95%CI 81.2-94.2) in some of the Brazilian health information systems researched. The search in other national health information systems would result in an increase of 57.1% of the reported cases. We identified no missed opportunities for the diagnosis of HIV+ in pregnant women in the maternity hospitals evaluated by the "Nascer no Brasil" study. The routine search for information in other Brazilian health information systems, a procedure carried out by the Ministry of Health for cases of AIDS in adults and children, should be adopted for cases of HIV in

2017-04-01

The enormous amount of information available in cell biology has created a challenge in selecting the core concepts we should be teaching our undergraduates. One way to define a set of essential core ideas in cell biology is to analyze what a specific cell biology community is teaching their students. Our main objective was to analyze the cell biology content currently being taught in Brazilian universities. We collected the syllabi of cell biology courses from public universities in Brazil and analyzed the frequency of cell biology topics in each course. We also compared the Brazilian data with the contents of a major cell biology textbook. Our analysis showed that while some cell biology topics such as plasma membrane and cytoskeleton was present in ∼100% of the Brazilian curricula analyzed others such as cell signaling and cell differentiation were present in only ∼35%. The average cell biology content taught in the Brazilian universities is quite different from what is presented in the textbook. We discuss several possible explanations for these observations. We also suggest a list with essential cell biology topics for any biological or biomedical undergraduate course. The comparative discussion of cell biology topics presented here could be valuable in other educational contexts. © 2017 The Authors.

The Brazilian's National Institute for Space Research (INPE), in collaboration with the Engineering School of Lorena/University of São Paulo (EEL/USP), the Federal University of Minas Gerais (UFMG), and the Brazilian's National Laboratory for Astrophysics (LNA), is developing a solar vector magnetograph and visible-light imager to study solar processes through observations of the solar surface magnetic field. The Brazilian Experimental Solar Telescope is designed to obtain full disk magnetic field and line-of-sight velocity observations in the photosphere. Here we discuss the system requirements and the first design review of the instrument. The instrument is composed by a Ritchey-Chrétien telescope with a 500 mm aperture and 4000 mm focal length. LCD polarization modulators will be employed for the polarization analysis and a tuning Fabry-Perot filter for the wavelength scanning near the Fe II 630.25 nm line. Two large field-of-view, high-resolution 5.5 megapixel sCMOS cameras will be employed as sensors. Additionally, we describe the project management and system engineering approaches employed in this project. As the magnetic field anchored at the solar surface produces most of the structures and energetic events in the upper solar atmosphere and significantly influences the heliosphere, the development of this instrument plays an important role in advancing scientific knowledge in this field. In particular, the Brazilian's Space Weather program will benefit most from the development of this technology. We expect that this project will be the starting point to establish a strong research program on Solar Physics in Brazil. Our main aim is to progressively acquire the know-how to build state-of-art solar vector magnetograph and visible-light imagers for space-based platforms.

Vowel insertion in the speech of Brazilian learners of English: a source of unintelligibility?

2008-01-01

Full Text Available http://dx.doi.org/10.5007/2175-8026.2008n55p133 This article is an attempt to answer the following question: Is vowel insertion in the speech of Brazilian learners of English likely to be a source of unintelligibility? Insights to answer this question are provided on the basis of an analysis of empirical data derived from three studies which investigated the pronunciation intelligibility of Brazilian learners' English to three different groups of listeners. Samples containing words with vowel insertion, produced  by Brazilian learners of English, were presented to three different groups of listeners who have the  following three characteristics: (1 British listeners living in Birmingham, England, unfamiliar with the way Brazilians pronounce English words (1st study; (2 British and American listeners living in Brazil, familiar with the way Brazilians pronounce English words (2nd study; and (3 a second group of American and British listeners, also familiar with the Brazilian way of pronouncing English words (3rd study. The listeners were asked to listen to the samples once, and to carry out tasks. In one of the tasks, they were required to write down what they had heard. The analysis focused on the stlisteners' orthographic transcriptions of the samples. On the basis of the results obtained, I argue that the category vowel insertion in itself is insufficient and too broad to provide an answer to such a question. Instead, I suggest that it is necessary to specify the type of vowel inserted, as well as the strength with which it is produced, when vowel insertion is considered in Brazilian learners' pronunciation intelligibility.

In the year 2007, ICRP published a set of recommendations (The 2007 Recommendations of the International Commission on Radiological Protection, Publication 103), which changed some important concepts. This work aims to compare the Brazilian radiation protection basic norm with the new ICRP recommendations, by checking the existing differences. The main difference between ICRP publication 60 and ICRP publication 103 is the changing of the concept of protection based on process, by using the concepts of practice and intervention, to the protection based in the exposition situation, by using the concepts of planned exposure, emergency and existing situation. Other important difference lies in the values of the radiation and tissue weighting factors, in the quantities equivalent and effective dose, and updating the radiation detriment based on the latest available scientific information of the biology and physics of radiation exposure. At last, the demonstration of the environment radiation protection must be clear, and this concept is not found in Brazilian nuclear legislation. Also some similarities were found. The fundamental principles of the Brazilian norms are the same as that of ICRP 103, which are the justification principle, the optimization principle and the application of dose limits. The individual effective dose limit of Brazilian norm is the same of the ICRP 103, established as 20 mSv per year. In order to adequate the Brazilian norm it is necessary to change its concept of protection and the values of radiation and tissue weighting, and updating the radiation detriment, besides making clear the concept of protection of the environment. It is important to notice that although the Brazilian norm is not in complete agreement with all international recommendations, it must be completely followed as the norm which is in use in the country.

The purpose of this study was to perform the cultural adaptation of the Brazilian version of the Vocal Fatigue Index (VFI). Two Brazilian bilingual speech-language pathologists (SLP) translated the original version of the VFI in English into Portuguese. The translations were reviewed by a committee of five voice specialist SLPs resulting in the final version of the instrument. A third bilingual SLP back-translated this final version and the same committee reviewed the differences from its original version. The final Portuguese version of the VFI, as in the original English version, was answered on a categorical scale of 0-4 indicating the frequency they experience the symptoms: 0=never, 1=almost never, 2=sometimes, 3=almost always, and 4=always. For cultural equivalence of the Portuguese version, the option "not applicable" was added to the categorical scale and 20 individuals with vocal complaints and dysphonia completed the index. Questions considered "not applicable" would be disregarded from the Brazilian version of the protocol; no question had to be removed from the instrument. The Brazilian Portuguese version was entitled "Índice de Fadiga Vocal - IFV" and features 19 questions, equivalent to the original instrument. Of the 19 items, 11 were related with tiredness of voice and voice avoidance, five concerned physical discomfort associated with voicing, and three were related to improvement of symptoms with rest or lack thereof. The Brazilian version of the VFI presents cultural and linguistic equivalence to the original instrument. The IFV validation into Brazilian Portuguese is in progress.

The Pelvic Floor Bother Questionnaire (PFBQ) was designed to identify the presence and degree of bother associated with common pelvic floor symptoms. The PFBQ can be used in clinical practice and for research purposes, but it is not available in Brazilian Portuguese. We aimed to validate a cross-culturally adapted Brazilian Portuguese version of the PFBQ. A pilot-tested version of the PFBQ translated from English was evaluated with Brazilian patients suffering from pelvic floor disorders. Internal reliability, test-retest reliability, validity, and responsiveness to change were assessed. A total of 147 patients (mean age, 60.49 years) were enrolled in the study. The Brazilian Portuguese version of the PFBQ demonstrated good reliability (α = 0.625; ICC = 0.981). There was strong agreement beyond chance for each item (κ = 0.895-1.00). The PFBQ correlated with stage of prolapse (p Portuguese version of the PFBQ is a reliable, valid, and user-friendly instrument that can be used for assessing the presence and severity of pelvic floor symptoms in clinical and research settings in Brazil.

Capoeira Angola and its relations with the myth of Brazilian racial democracy

Gabriela Balaguer

2017-06-01

Full Text Available Capoeira is a cultural manifestation widely known as part of Brazilian identity and culture both by Brazilians and foreigners. Nevertheless, for being originally a black popular culture, it must be understood in relation to the dominant culture, where elements of resistance and consent are present (HALL, 2013. In the nineteenth and in the beginning of the twentieth century, capoeira was strongly repressed by the State, driving the blacks away from the construction of national identity based on racial and ethnic grounds (REIS, 2000. In the 30's, a new narrative of Brazilian identity, known as Brazilian racial democracy, treasured the cultural and biological integration of the three existing races in Brazil (SCHWARZ, 2012; MUNANGA, 1996. Along with other cultural and religious manifestations, capoeira is now valued and integrated into the State (PIRES, 2010. The text aims at raising aspects that allow a reappraisal of how the Angola capoeira relates to racial and ethnic issues, based on questioning the myth of racial democracy and the contribution of cultural studies (MUNANGA, 1996; CARONE; BENTO, 2002; HALL, 2013.

The bone mineral density (BMD) can vary according with color, sex, feed and knowing the miscegenation and nutritional state of the Brazilian people; it is obvious that the fixed values of Caucasian females BMD cannot be employed to the Brazilian women. We have studied 158 Brazilian women with average age of 42 ± 14 years in whom it was settled the BMD over the lumbar vertebral column (L2, L3 and L4) and the femoral neck with a gadolinium-153 source double-photon densitometer and analyzed images in a IBM/PC/AT 286 processor computer. It was determined the linear regression equation corresponding to the variation of the bone mineral density as a function of age. The results were: BMD-lumbar column = 1.405 - 0.0086 x age ± 0.013 g/cm 2 and BMD-femoral neck = 0.909 - 0.0034 x age ± 0.11 g/cm 2 preferred to the age group between 25 to 80 years old. The results analysis shows that the Brazilian women BMD is lesser than the Caucasian. (author)

Incoherences of Brazilian labour laws face to present radioprotection concepts

Borges, J.C.

1996-01-01

The Brazilian labour legislation establishes, since 1950, some privileges for people working in activities which imply exposure to ionizing radiations. Comparing the present legal framework with technical radioprotection knowledge, one can detect several incoherences covering: classification of such activities; additional payments; reduced labour journey; more vacations; medical surveillance; early retirements; special norms for women. An analysis of these incoherences lead us to propose a new frame of labour rights and radioprotection norms, coupling Brazilian juridical principles and modern radioprotection knowledge. (author)

Methods of soil organic carbon determination in Brazilian savannah soils

Juliana Hiromi Sato

2014-08-01

Full Text Available Several methods exist for determining soil organic carbon, and each one has its own advantages and limitations. Consequently, a comparison of the experimental results obtained when these methods are employed is hampered, causing problems in the comparison of carbon stocks in soils. This study aimed at evaluating the analytical procedures used in the determination of carbon and their relationships with soil mineralogy and texture. Wet combustion methods, including Walkley-Black, Mebius and Colorimetric determination as well as dry combustion methods, such as Elemental and Gravimetric Analysis were used. Quantitative textural and mineralogical (kaolinite, goethite and gibbsite analyses were also carried out. The wet digestion methods underestimated the concentration of organic carbon, while the gravimetric method overestimated. Soil mineralogy interfered with the determination of carbon, with emphasis on the gravimetric method that was greatly influenced by gibbsite.

Computed tomography has promoted improvement of the diagnostic process by producing anatomical cut images with high quality and contrast between soft tissues which have very similar absorption of the X-ray beams. The objective of this study is to evaluate the technological park of CT in Brazil correlated with the wide world, and carry out studies of experimental dosimetry to understand the dose distribution feature using phantoms and different methods of measurement of kerma index, as well as perform measures of local doses in sensitive organs. To study the scanner geographic distribution and supply of computed tomography tests in Brazil, a comparison has been made with results found with the specified reference by Brazilian law (Ordinance GM / MS No. 1101, 2002; Resolution RE nº1016, 2006). For dosimetry studies, It was used a standard chest phantom and the anthropomorphic phantom. For image quality evaluation, it was used the CATPHAN-600 phantom. Scans were performed in a GE scanner, Discovery model with 64 channels. Dose measurements have been performed by using a pencil ionization chamber, thermoluminescent dosimeters and radiochromic film strips. Sensitive organ shielding devices were evaluated in order to verify their efficiency in organ dose reduction and its influence in the quality of image. Considering Brazilian population, the scanner park showed a greater amount than the minimum parameter recommended by Brazilian law. Dose measurements using three different methods showed the correct procedure of metrological reliability of the measurement system. The findings and conclusions of this study may contribute to the improvement of local practices in Computed Tomography tests, inserted in context of radiological protection in order to define reference levels for optimized diagnosis, and image quality control.

The aim of this work was to irradiate brazilian grape tree wines with gamma radiation (Co{sup 60}) to investigate the effect of radiation on its components and to create a new product for the superior quality fermented beverages market. For this wine was produced in an artisan way, but with all the care of hygiene and sanitation. The brazilian grape tree was fermented for five days and the wine was then filtered and stored in inert material containers then irradiated at 2.5 and 5 kGy doses. The samples were evaluated in relation to the radiation doses used. Physical and chemical analyzes of pH; total and volatile acidity; alcohol content; anthocyanins; tannins and colorimetry were performed. As a result, in most product analysis, had little effect on irradiation, except for anthocyanins and tannins. For this can be concluded that it is possible to develop a new fermented drink based on brazilian grape tree, according to the standards required by the legislation and that the irradiation at the dose of 5kGy was the sample that shown to have the most effect on the color because it was the one that degraded most molecules of anthocyanins and tannins.

Full Text Available The narrow genetic variability of grasslands and the incidence of new biotic and abiotic stresses have motivated the selection of new Panicum maximum genotypes for use as forage for beef cattle in the Brazilian savannah. This study aimed to evaluate forage yield and nutritive value of P. maximum genotypes including 14 accessions (PM30 to PM43, four intraspecific hybrids (PM44 to PM47 and six cultivars (Aruana, Massai, Milênio, Mombaça, Tanzania and Vencedor, examining 24 genotypes over two years (2003 and 2004. Milênio cultivar was the genotype with the highest dry matter yield (DMY in both years (18.4 t ha-1 and 20.9 t ha-1, respectively although it presented a high proportion of stems (~ 30%. Genotypes that showed higher Leaf DMY in both years were the accession PM34 (14.7 t ha-1 and the hybrid PM46 (14.0 t ha-1, while Mombaça and Tanzania yielded 12.5 and 11.0 t ha-1, respectively. Leaf organic matter digestibility and leaf DMY for PM40 and PM46 genotypes exceeded the mean (> 656 g kg-1 and > 11.7 t ha-1, respectively. For this reason, PM40 and PM46 can be considered promising P. maximum genotypes for use as forage for grazing systems in the Brazilian savannah.

To compare clinical trials published in Brazilian journals of ophthalmology and in foreign journals of ophthalmology with respect to the number of citations and the quality of reporting [by applying the Consolidated Standards for Reporting Trials (CONSORT) statement writing standards]. The sample of this systematic review comprised the two Brazilian journals of ophthalmology indexed at Science Citation Index Expanded and six of the foreign journals of ophthalmology with highest Impact Factor® according ISI. All clinical trials (CTs) published from January 2009 to December 2010 at the Brazilians journals and a 1:1 randomized sample of the foreign journals were included. The primary outcome was the number of citations through the end of 2011. Subgroup analysis included language. The secondary outcome included likelihood of citation (cited at least once versus no citation), and presence or absence of CONSORT statement indicators. The citation counts were statistically significantly higher (Pjournals of ophthalmology still are low when compared with the foreign journals of ophthalmology with highest Impact Factor®.

EMPHASIZING SOCIAL ISSUES TOWARD SUSTAINABLE SUPPLY CHAIN: A BRAZILIAN PERSPECTIVE

Directory of Open Access Journals (Sweden)

Minelle Enéas da Silva

2015-06-01

Full Text Available From sustainability perspective, the supply chain management strategy can use different indicators related to Triple Bottom Line to improve its practices. Some studies in the topic have focused only environmental issues; however in some cases the social issues should be considered as a core of the sustainable strategies. Considering this view, the paper aims to highlight the relevance of social issues in the Brazilian context toward sustainable supply chain. Therefore, a theoretical essay was conducted using the literature about sustainable supply chain in relation to the Brazilian perspective to understand how it is possible to use new approaches for a more emphasis on social issues. The discussions indicates that to re-conceptualize the social relations in supply chains, it's necessary to use corporate social responsibility and social capital approaches to create a better discussion about sustainable supply chain. The proposal starts a discussion in the Brazilian context to stimulate new scholars to study this topic.

BRAZILIAN FOREST SEEDS: A PRECARIOUS BEGINNING, A HEADY PRESENT AND THE FUTURE, WILL IT BE PROMISING?

2014-09-01

Full Text Available http://dx.doi.org/10.5902/1980509815738By analyzing the trajectory of forest seed sector, it is widely known the relationship between the studies on native species and the Brazilian Forest Legislation. The Brazilian market for forest seed species is mostly informal and there are only a few species with laboratory tests registered in the Rules for Seed Testing (RAS. However, Law number 10,711, when ruling as to the marketing of seeds and seedlings, granted legal subsidies to promote the formalization of the forest seeds industry. Compliance with this law is conditioned to standardized laboratory methodologies for evaluating seed quality. For this reason, the formulation of a supplement or specific RAS for native forest seeds seems to be near. This fact will certainly consolidate the national seed industry sector. However, what were the paths that native forest seed science had to walk down to reach this standardization? What are the prospects for the future relating to the native forest seed sector? These are just some of the questions this work intends to answer, based on the perspectives of forestry and environmental organizations, such as the Seeds Networks.

Full Text Available Brazilian soccer teams are required to present good results inside and outside the field. The main demand is about winning titles, to present continuous and increasing profits, and, consequently, to reach economic-financial stability. The present study aims at analyzing the relationship between the ranking formed by the Brazilian Soccer Confederation (CBF and the economic-financial indicators of the Brazilian soccer teams. The sample consisted of 36 Brazilian soccer teams that belong to the series A, B and C. Such teams are linked to CBF and published their financial statements of 2014. For data analysis, we used multi-criteria decision making method VIKOR that was applied along with Kendall rank correlation. Results revealed that the majority of Brazilian soccer teams have insufficient economical liquidity; they cannot bear their own expenses; they dependent of third-party resources; and they present negative profitability. Results also showed, through VIKOR technique, that the soccer teams studied occupy different positions in CBF ranking and in the economical-financial indicators, except for Botafogo club. Kendall rank correlation revealed no correlation and no significance between the rankings. Findings seem to support the idea that there is no relationship between CBF rankings and the economical-financial indicators of Brazilian soccer teams.

To describe opinions and attitudes concerning sexuality of the Brazilian urban population. A population survey was carried out in 2005 on a representative sample of 5,040 interviewees. An analysis of the attitudes regarding sexual initiation and sexual education of teenagers, considering gender, age, schooling, income, marital status, color, geographic region and opinion on fidelity, homosexuality, and masturbation. The results were contrasted with a similar survey carried out in 1998, when possible. Most interviewees selected the "sex is evidence of love" option when describing the meaning of sex. As in 1998, the majority was in favor of sexual initiation after marriage (63.9% for women vs. 52.4% for men initiation); results differed among religions. School teenage education on the use of condoms was supported by 97% of the interviewees across all social groups. The proportion of Brazilians who agreed with having access to condoms in health services (95%) and at school (83.6%) was high. Fidelity remained an almost unanimous value and there was an increase, in 2005, in the proportion of those in favor of sexual initiation after marriage, and in the rate of acceptance of masturbation and homosexuality compared to the 1998 survey. The younger generations tend to be more tolerant and egalitarian. As observed in other countries, this study confirms the difficulty in establishing a single dimension that guides sexual life ("liberal" vs "conservative"). The study suggests that the normativity concerning sexual activity should be understood in the light of the local culture and social organization of sexuality, considered by the STD/Aids programs. Opinions in favor of free access to preservatives at school clash with the slower results obtained in fighting the stigma and discriminating against homosexual minorities. The design of laical policies on sexuality allow for the dialog across different perspectives.

German-Brazilian nuclear deal

International Nuclear Information System (INIS)

Krugmann, H.

1981-01-01

Examination of the arguments in favor of the nuclear deal with West Germany and the resulting program suggests that revisions of both are in order to make them more compatible with Brazil's national interests. The deficiencies of current policy appear to be too weighty and numerous to be ignored. Sooner or later the government will have to move toward adjusting its nuclear agreement with West Germany, if not for the reasons discussed here then for lack of capital. Current estimates of the nuclear package lie in the range of $25 to $30 billion, compared to an initial projection of about $5 billion. The deal has become so expensive that it would draw capital from the hydropower and alcohol programs essential for the short and medium-term energy needs of the country. Mr. Krugman feels the Brazilian government should hold off on further nuclear contracts. And it should thoroughly reassess what Brazil's nuclear energy and technology requirements are and how to meet them. There are indications that the reassessment process is already underway. As long as the German nuclear industry depends on the sale of technology to Brazil, the Brazilian government will have considerable bargaining power to enforce further changes in the deal. If this power is used wisely, the result could be cooperation between the two countries toward nuclear options that are consistent with Brazil's energy and development needs

The Brazilian 2010 oil regulatory framework and its crowding-out investment effects

International Nuclear Information System (INIS)

Florêncio, Pedro

2016-01-01

Investment is an essential variable in the oil sector. It is even more important in the vast Brazilian pre-salt domains, where the technological requirements are high and sophisticated. The Brazilian National Oil Company, Petrobras, is facing severe financial limitations to undertake these disbursements. Other oil companies will therefore have to be significantly engaged in the endeavour, which reinforces further the importance of attracting investments in Brazil. Yet this article shows that the governance architecture established in the 2010 Brazilian oil framework will deter investments in several ways, giving rise to agency problems among entities and moral hazard situations because of contractual legal liabilities. There are some credible indications that the government of President Lula overestimated the attractiveness of the Brazilian pre-salt oil discoveries and their capacity to draw investments when proposing the 2010 changes. Little attention was given to the careful examination of how the framework would affect investors, under the assumption that the favourable geological conditions would be sufficiently attractive in themselves. Even though the 2010 reforms have brought some minor advancements and there have been some signs that the government has been recently attempting to mitigate some of the problems examined in this article, that is not enough. - Highlights: • The Brazilian regulatory oil framework deters investments in the country. • The governance setting between entities is one of its worse aspects. • It causes agency problems and moral hazard situations. • Brazil has to urgently tackle these investment hindrances.

Preliminary Characterization of Mitochondrial Genome of Melipona scutellaris, a Brazilian Stingless Bee

Directory of Open Access Journals (Sweden)

2014-01-01

Full Text Available Bees are manufacturers of relevant economical products and have a pollinator role fundamental to ecosystems. Traditionally, studies focused on the genus Melipona have been mostly based on behavioral, and social organization and ecological aspects. Only recently the evolutionary history of this genus has been assessed using molecular markers, including mitochondrial genes. Even though these studies have shed light on the evolutionary history of the Melipona genus, a more accurate picture may emerge when full nuclear and mitochondrial genomes of Melipona species become available. Here we present the assembly, annotation, and characterization of a draft mitochondrial genome of the Brazilian stingless bee Melipona scutellaris using Melipona bicolor as a reference organism. Using Illumina MiSeq data, we achieved the annotation of all protein coding genes, as well as the genes for the two ribosomal subunits (16S and 12S and transfer RNA genes as well. Using the COI sequence as a DNA barcode, we found that M. cramptoni is the closest species to M. scutellaris.

Costa, Ana Lucia Siqueira; Heitkemper, Margaret M; Alencar, Gizelton Pereira; Damiani, Lucas Petri; Silva, Rodrigo Marques da; Jarrett, Monica E

The well-being of patients undergoing chemotherapy treatment for colorectal cancer (CRC) is affected by psychological effects associated with cancer treatment. However, little is known about the impact of these psychological factors in Brazilian patients with CRC. The aim of this study was to determine whether perceived stress, social support, and resilience are associated with quality of life in urban Brazilian patients receiving chemotherapy treatment for CRC. This was a cross-sectional study conducted with 144 Brazilian CRC patients in an ambulatory oncology clinic. The participants completed 5 questionnaires: Demographics, Perceived Stress Scale 14, Social Support Satisfaction Scale, Resilience Scale, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaires (C30 and CR29). Confirmatory factor analysis modeling and Cronbach's α were used to examine construct validity and internal consistency. We used the MPlus 3.0 to construct and validate the structural model. There was a moderate and positive effect of resilience on the physical, social, and emotional aspects of quality of life. Social support had a strong and positive direct effect on quality of life (ie, social, physical, social, and emotional). Social support had a negative effect on stress perception. Resilience was also negatively related to stress perception. Family support and professional social support are important factors for Brazilian CRC patients. Resilience is an important ally for patients. It is important for nurses to consider this when developing educational and psychological interventional strategies to reduce stress and ultimately improve quality of life in this population. Psychological factors that improve quality of life should be evaluated in patients undergoing treatment for cancer.

Full Text Available Objective: To translate and adapt to Brazilian Portuguese the Revised Reading the Mind in the Eyes Test (RMET, in both paper-and-pencil and computerized versions. The RMET is a well-accepted instrument for assessment of Theory of Mind (ToM, an important component of social cognition. Methods: Following a guideline for translation of material for clinical populations, this study had three main phases: 1 formal translation and semantic adaptation to Brazilian Portuguese; 2 an acceptability trial with health professionals as judges evaluating picture-word matching; and 3 a trial using the paper-and-pencil and computerized versions (experiments built in E-Prime 2.0.10 software with healthy participants to test whether the instrument has similar outputs to those expected in versions in other languages. Results: RMET was adequately adapted to Brazilian Portuguese. This version showed acceptability and outputs similar to versions of the instrument in other languages, including the original one. We kept the same number of images as the original English version. Conclusions: Considering the scarcity of cognitive assessment instruments adequately adapted to Portuguese and the importance of social cognition in many psychiatric disorders, this work adds an important resource to Brazilian research and is administrable in both paper-and-pencil and computerized versions.

The Performative Force of Bodies: Affective Realism in Contemporary Brazilian Cinema

2015-10-01

Full Text Available http://dx.doi.org/10.5007/2175-8026.2015v68n3p161 This paper traces the emergence of a younger generation of Brazilian filmmakers whose works bypass traditional themes in Brazilian cinema such as urban violence and historical revisionism to engage in post-identity politics avoiding narratives of nation, class and gender. One of the most prominent features in these recent works is a questioning of the status of the image, which vacillates between fiction and documentary without a point of resolution. This vacillation can be understood in terms of the performative nature of films like The Monsters, The Residents, The Earth Giveth, The Earth Taketh and Avenida Brasilia Formosa. Such films are centered around improvisations that open up the image to the real. Therefore, these films produce a space between fiction and documentary, between reality and artifice that is productive and politically charged. This proposal aims at discussing this “Brand New” Brazilian Cinema (Novísssimo Cinema Brasileiro and the performative force of bodies in its affective realism. No longer a referent for a sociological truth about Brazilian society, realism is taken as something that the image does, i. e., as an affect that challenges the viewer's response-ability.

The Cardiff Acne Disability Index was originally developed in English for measuring quality of life of acne patients. Considering the psychosocial impact of this disease, it is important to have instruments culturally and linguistically validated for use in Brazilian adolescents. To translate the Cardiff Acne Disability Index into Brazilian Portuguese, culturally adapt it, and verify its reliability and validity in adolescent patients with acne. In the first step, the Cardiff Acne Disability Index was translated and validated linguistically to Brazilian Portuguese in accordance with international guidelines published. In the second step, the validation of the Cardiff Acne Disability Index into Brazilian Portuguese instrument was performed, when patients aged from 12 to 20 years with acne were selected. The participants were interviewed to collect demographic data, submitted to the classification of acne by the Global Acne Grading System and invited to respond the Cardiff Acne Disability Index into Brazilian Portuguese version and DLQI (>16 years) or CDLQI (≤16 years). The internal consistency of Cardiff Acne Disability Index into Brazilian Portuguese was assessed by Cronbach's alpha coefficient and concurrent validity was measured by the Spearman correlation coefficient and Student 's t-test for paired samples. The study included 100 adolescents. The Cardiff Acne Disability Index into Brazilian Portuguese version showed good reliability and internal consistency (Cronbach's alpha = 0.73). The concurrent validity of the scale was supported by a strong and significant correlation with CDLQI / DLQI instruments (rs=0.802;pPortuguese version is a reliable, valid and valuable tool to measure the impact of acne on quality of life in adolescent patients.

Fernanda Bernadelli Garcia

2012-08-01

Full Text Available INTRODUCTION: The cytolysis mediated by granules is one of the most important effector functions of cytotoxic T lymphocytes and natural killer cells. Recently, three single nucleotide polymorphisms (SNPs were identified at exons 2, 3, and 5 of the granzyme B gene, resulting in a haplotype in which three amino acids of mature protein Q48P88Y245 are changed to R48A88H245, which leads to loss of cytotoxic activity of the protein. In this study, we evaluated the frequency of these polymorphisms in Brazilian populations. METHODS: We evaluated the frequency of these polymorphisms in Brazilian ethnic groups (white, Afro-Brazilian, and Asian by sequencing these regions. RESULTS: The allelic and genotypic frequencies of SNP 2364A/G at exon 2 in Afro-Brazilian individuals (42.3% and 17.3% were significantly higher when compared with those in whites and Asians (p < 0.0001 and p = 0.0007, respectively. The polymorphisms 2933C/G and 4243C/T also were more frequent in Afro-Brazilians but without any significant difference regarding the other groups. The Afro-Brazilian group presented greater diversity of haplotypes, and the RAH haplotype seemed to be more frequent in this group (25%, followed by the whites (20.7% and by the Asians (11.9%, similar to the frequency presented in the literature. CONCLUSIONS: There is a higher frequency of polymorphisms in Afro-Brazilians, and the RAH haplotype was more frequent in these individuals. We believe that further studies should aim to investigate the correlation of this haplotype with diseases related to immunity mediated by cytotoxic lymphocytes, and if this correlation is confirmed, novel treatment strategies might be elaborated.

Full Text Available The aim of this study was to determine the energy requirements for maintenance (NEm and growth of 48 Brazilian Somali ram lambs with an average initial body weight of 13.47±1.76 kg. Eight animals were slaughtered at the trials beginning as a reference group to estimate the initial empty body weight (EBW and body composition. The remaining animals were assigned to a randomised block design with eight replications per block and five diets with increasing metabolisable energy content (4.93, 8.65, 9.41, 10.12 and 11.24 MJ/kg dry matter. The logarithm of heat production was regressed against metabolisable energy intake (MEI, and the NEm (kJ/kg0.75 EBW/day were estimated by extrapolation, when MEI was set at zero. The NEm was 239.77 kJ/kg0.75 EBW/day. The animal’s energy and EBW fat contents increased from 11.20 MJ/kg and 208.54 g/kg to 13.54 MJ/kg and 274.95 g/kg of EBW, respectively, as the BW increased from 13 to 28.70 kg. The net energy requirements for EBW gain increased from 13.79 to 16.72 MJ/kg EBW gain for body weights of 13 and 28.70 kg. Our study indicated the net energy requirements for maintenance in Brazilian Somali lambs were similar to the values commonly recommended by the United States’ nutritional system, but lower than the values recommended by Agricultural Research Council and Commonwealth Scientific and Industrial Research Organization. Net requirements for weight gain were less compared to the values commonly recommended by nutritional system of the United States.

Kibrit, Eduardo

2008-01-01

The present work identifies, characterizes and analyses the normative requirements for the development and implementation of quality management systems in Brazilian nuclear installations and activities. The requirements established in standards IAEA GS-R-3, IAEA GS-G-3.1, IAEA DS 349, NBR ISO 9001:2000 e CNEN-NN-1.16 are critically analyzed. A correlation matrix of the applicable standards is presented and the related topics among them are identified. The standards IAEA GS-R-3, IAEA GS-G-3.1 and IAEA DS 349 define general requirements for establishing, implementing, assessing and continually improving an integrated management system in nuclear installations and activities, in IAEA member countries. The standard NBR ISO 9001:2000 establishes general requirements for the implementation of a quality management system in all kinds of organizations. The standard CNEN NN-1.16 establishes the regulating requirements for the quality assurance systems and programs of nuclear installations, for licensing and authorization for operation of these installations in Brazil. The standard IAEA GS-R-3 that replaces the code IAEA 50-C-Q introduces the concept of 'Integrated Management System' for the nuclear area, in preference to the concepts of 'Quality Assurance' and 'Quality Management'. This new approach is aligned with the current tendency incorporating requirements of quality, safety, health, environment, security, economics and other in a unique management system. Examples of quality management systems implemented by Brazilian nuclear organizations and by nuclear organizations outside Brazil are analyzed and considered in the discussion of results. (author)

Full Text Available This paper studies the technological capability in the Brazilian Official Pharmaceutical Laboratories [OPL]. The technological capability analysis could contribute to organization strategies and governmental actions in order to improve OPL basic tasks as well to incorporate new ones, particularly concerning the innovation management. Inspired in Figueiredo (2000, 2003a, 2003b and Figueiredo and Ariffin (2003, a framework was drawn and adapted to pharmaceutical industry characteristics and current sanitary and health legislation. The framework allows to map different dimensions of the technological capability (installations, processes, products, equipments, organizational capability and knowledge management and the level attained by OPL (ordinary or innovating capability. OPL show a good development of ordinary capabilities, particularly in Product and Processes. Concerning the other dimensions, OPL are quite diverse. In general, innovating capabilities are not much developed. In the short term, it was identified a dispersion in the capacitating efforts. Considering their present level and the absorption efforts, good perspectives can be found in Installations, Processes and Organizational Capability. A lower level of efforts in Products and Knowledge Management could undermine these capabilities in the future.

Full Text Available OBJECTIVE: To evaluate how the country of origin affects the probability of being delivered by cesarean section when giving birth at public Portuguese hospitals. STUDY DESIGN: Women delivered of a singleton birth (n = 8228, recruited from five public level III maternities (April 2005-August 2006 during the procedure of assembling a birth cohort, were classified according to the country of origin and her migration status as Portuguese (n = 7908, non-Portuguese European (n = 84, African (n = 77 and Brazilian (n = 159. A Poisson model was used to evaluate the association between country of birth and cesarean section that was measured by adjusted prevalence ratio (PR and respective 95% confidence intervals (95%CI. RESULTS: The cesarean section rate varied from 32.1% in non-Portuguese European to 48.4% in Brazilian women (p = 0.008. After adjustment for potential confounders and compared to Portuguese women as a reference, Brazilian women presented significantly higher prevalence of cesarean section (PR = 1.26; 95%CI: 1.08-1.47. The effect was more evident among multiparous women (PR = 1.39; 95%CI: 1.12-1.73 and it was observed when cesarean section was performed either before labor (PR = 1.43; 95%CI: 0.99-2.06 or during labor (PR = 1.30; 95%CI: 1.07-1.58. CONCLUSIONS: The rate of cesarean section was significantly higher among Brazilian women and it was independent of the presence of any known risk factors or usual clinical indications, suggesting that cultural background influences the mode of delivery overcoming the expected standard of care and outcomes in public health services.

The main objective of this study was to evaluate the prevalence of emergencies in dental practices and the prepared-ness and the training experience in cardiopulmonary resuscitation (CPR) of Brazilian dentists in dealing with emergencies. The volunteer participants in the study were 498 Brazilian dentists who were present at the 27th International Congress of Dentistry in São Paulo. The most prevalent emergency was presyncope (reported by 54.20 percent of respondents), followed by orthostatic hypotension (44.37 percent), moderate allergic reactions (16.86 percent), hypertensive crisis (15.06 percent), asthma (15.06 percent), syncope (12.65 percent), angina (6.82 percent), convulsion (6.22 percent), hypoglycemia (5.62 percent), hyperventilation crisis (5.22 percent), choking (2.20 percent), and cerebrovascular accident (0.8 percent). Anaphylaxis, myocardial infarction, and cardiac arrest were the rarest emergencies, reported by only 0.4, 0.2, and 0.2 percent of dentists, respectively. Only 41 percent of the dentists judged themselves capable to diagnose the cause of an emergency during a dental visit. The majority responded that they would be capable of performing initial treatment of presyncope, syncope, orthostatic hypotension, convulsion, and choking. However, most of them felt unable to treat anaphylaxis, myocardial infarction, or cardiac arrest. Further, the majority felt unable to perform CPR or undertake an intravenous injection. It was concluded that the most prevalent medical emergencies in dental practice of Brazilian dentists are presyncope and orthostatic hypotension. The occurrence of life-threatening medical emergencies like anaphylaxis, myocardial infarction, cardiac arrest, and cerebrovascular accident is rare. Brazilian dentists are not fully prepared to manage medical emergencies and have insufficient experience training in CPR.

Full Text Available ABSTRACT This research analyses how the interaction between strategy capabilities, strategy types, strategy formulation quality and implementation capability affect organizational performance in Brazilian textiles companies. This article proposes and tests a conceptual framework, using a structural equation modeling of a set of 211 valid questionnaires on Brazilian textiles firms. The results support links between focus strategy and marketing capabilities, and between cost leadership strategy and management capabilities. However, the relationship between technologic capabilities and differentiation strategy was not statistically significant. The existence of an inter-relationship between generic strategies of focus, cost leadership and differentiation indicates the use of combined strategies. Concerning the firms' financial performance, the results show that management capability and market performance have a statistically significant relationship with financial performance.

The profiles of proteins present in the exoantigens of Brazilian Sporothrix schenckii isolates were studied and compared by electrophoresis (SDS-PAGE). Thirteen isolates from five different regions of Brazil (1,000 to 2,000 km apart) and ten from a more limited region (200 to 400 km apart within the state of São Paulo) were cultured in Sabouraud, M199 and minimum (MM) media. Qualitative and quantitative differences in the expression of proteins, which varied according to the medium and the isolate, were observed. Fractions with the same MW but varying in intensity were detected, as well as fractions present in 1 isolate but absent in others. Dendrograms were constructed and isolates grouped based on the fractions obtained, irrespective of the intensity. The results showed that Brazilian S. schenckii isolates express different protein profiles, a feature also present in isolates from a more restricted region. The exoantigens were found to have a maximum of 15 protein fractions, ranging in MW from 19-220 KDaltons depending on the medium used for the cultures. These data show the great heterogeneity of Brazilian S. schenckii protein expression.

Rural electrification of the Brazilian Amazon - Achievements and lessons

International Nuclear Information System (INIS)

Gomez, Maria F.; Silveira, Semida

2010-01-01

The Brazilian government has the ambition to provide complete electricity coverage for all citizens as a means to promote development and reduce inequalities. Full coverage implies the provision of electricity to 15 million people in the country by the end of 2010 through the program Luz para Todos (LPT - light for all) launched in 2003. So far, 11 million people have benefited, 2 million of which live in the Amazon. In this paper, we analyze the linkages between development and rural electrification through the Human Development Index (HDI) and within the context of the Amazon. We examine the suitability of the HDI as a planning and monitoring tool for improving energy access and development. We show that the recognition of electricity access as a driver for development has led to concrete goals for electrification, actual action and welfare improvement. Our study serves to highlight the role of LPT in the development of the Amazon region, and the specific features and achievements of the Brazilian policy for universal electrification. We conclude that some challenges related to the electrification of isolated areas still lie ahead. We finalize with a discussion on the relevance of the Brazilian experience to other developing countries.

To construct versions of the WHOQOL-BREF and WHOQOL-DIS instruments in Brazilian sign language to evaluate the Brazilian deaf population's quality of life. The methodology proposed by the World Health Organization (WHOQOL-BREF and WHOQOL-DIS) was used to construct instruments adapted to the deaf community using Brazilian Sign Language (Libras). The research for constructing the instrument took placein 13 phases: 1) creating the QUALITY OF LIFE sign; 2) developing the answer scales in Libras; 3) translation by a bilingual group; 4) synthesized version; 5) first back translation; 6) production of the version in Libras to be provided to the focal groups; 7) carrying out the Focal Groups; 8) review by a monolingual group; 9) revision by the bilingual group; 10) semantic/syntactic analysis and second back translation; 11) re-evaluation of the back translation by the bilingual group; 12) recording the version into the software; 13) developing the WHOQOL-BREF and WHOQOL-DIS software in Libras. Characteristics peculiar to the culture of the deaf population indicated the necessity of adapting the application methodology of focal groups composed of deaf people. The writing conventions of sign languages have not yet been consolidated, leading to difficulties in graphically registering the translation phases. Linguistics structures that caused major problems in translation were those that included idiomatic Portuguese expressions, for many of which there are no equivalent concepts between Portuguese and Libras. In the end, it was possible to create WHOQOL-BREF and WHOQOL-DIS software in Libras. The WHOQOL-BREF and the WHOQOL-DIS in Libras will allow the deaf to express themselves about their quality of life in an autonomous way, making it possible to investigate these issues more accurately.

Pfatp6 molecular profile of Plasmodium falciparum isolates in the western Brazilian Amazon

2012-04-01

Full Text Available Abstract Background Anti-malarial drug resistance has emerged as one of the biggest challenges confronting the worldwide effort to control malaria. The appearance of chloroquine and multi-drug resistance had devastating effects on therapeutic efficacy of former first-line agents. Artemisinin has proven to be an excellent therapeutic alternative to fill the void in chemotherapeutic options left by resistance mechanisms. At the time of introduction, no resistance to artemisinins had been recorded, and artemisinins demonstrated excellent parasite reduction rates. In an attempt to protect artemisinin efficacy, the World Health Organization (WHO made artemisinin-based combination therapy (ACT its official first-line treatment recommendation for uncomplicated Plasmodium falciparum in 2006. In Brazil, artemether/lumefantrine became the Brazilian Malaria Control Programme's official treatment recommendation in 2007. The sarco/endoplasmic reticulum Ca2+ - ATPase ortholog of P. falciparum (pfatp6 has been suggested as one of the targets of artemisinins. Consequently, pfatp6 gene polymorphisms are being investigated as markers of artemisinin resistance elsewhere. The goal of this work was to describe the molecular profile of pfatp6 in P. falciparum isolates from different localities in the Amazonas State. Methods DNA polymorphisms of the pfatp6 gene in 80 P. falciparum isolates from 11 municipalities of the Amazonas State (Western Brazilian Amazon, before and after the introduction of ACT in the Brazilian anti-malarial guidelines, were analysed by automatic sequencing. Mutations in the pfatp6 gene were searched using Mutation Surveyor v3.25 software. Results The P. falciparum pfatp6 gene presented polymorphisms at codons 37, 630 and 898. The R37K mutation was found in 16% of the samples, A630S in 32% and I898I in 52%. No S769N mutation, however, was detected in the analysed samples. Conclusion Despite the small number of samples, data presented here

On the southeastern Brazilian coast, mangrove organic matter records have been studied by C and N isotopes, pollen and diatom analysis to reconstruct 40 ka of vegetation and climatic history. The {delta}{sup 13}C and {delta}{sup 15}N presented more depleted values from 40 to 19 ka BP. The high C/N ratios and depleted isotopic values indicate the predominance of C3 land plants in the location presently occupied by the mangrove vegetation, and a lower sea level than today. The presence of pollen of Ilex, Weinmannia, Symplocos, Drimys and Podocarpus suggest a colder and more humid climate than present. From 19 to 2.2 ka BP a sedimentary hiatus is associated with a sea level rise. The presence of mangrove in its present position since at least 2.200 a BP and the return of the marine coastline are associated with the lowest C/N ratio, more enriched {delta}{sup 13}C and {delta}{sup 15}N values and the presence of marine diatoms.

The aim of this study was to investigate the relationship between food insecurity and nutritional status of Brazilian children. The National Demographic and Health Survey 2006 database is available on the worldwide web. Thus, the analyzed variables were obtained in this study, including nutritional indices, food insecurity and other socioeconomic and demographic variables. The height-for-age, weight-for-age and weight-for-height indices were evaluated as the Z-score of the World Health Organization reference curves. Food insecurity was defined by using the Brazilian Food Insecurity Scale. Averages of three indices according to the presence of food insecurity were analyzed, including other variables. Linear regression evaluated the effect of food insecurity on the Z-score of the three nutritional indices. The sample included 4,817 children, out of whom 7% had deficit in height, 7% were overweight and 47% had food insecurity. It was found that the average of height-for-age, weight-for-age and weight-for-height were -0.31, 0.12 and 0.40, respectively, being lower among children with food insecurity. The regression analysis showed that children living with some level of food insecurity have worse rates of height-for-age, even controlling for demographic and socioeconomic factors.

Catalogue of distribution of lizards (Reptilia: Squamata) from the Brazilian Amazonia. III. Anguidae, Scincidae, Teiidae.

2016-12-09

We present distribution data of all Anguidae, Scincidae, and Teiidae lizards known from the Brazilian Amazonia, totaling 29 species-level taxa, belonging to 14 genera. This represents 11 more species-level taxa than previously reported for these families in this area. Data were based on literature and 46,806 specimens deposited in three North American and eight Brazilian museums, including the main collections harboring Amazonian material. Most species (~55%) are endemic to Amazonia. Except for Ameiva ameiva, that is present in several environments and domains, non-endemic species are either associated with open dry (semideciduous) forest or open vegetation (savanna) enclaves in Amazonia, occupying similar environments outside Amazonia, gallery forests within the Cerrado, or present disjunct populations in the Atlantic Forest. As a whole, six taxa are widespread in Amazonia, four are restricted to eastern Amazonia, four to western Amazonia, three to southwestern Amazonia, one to northern Amazonia, and seven to the southern peripheral portion of Amazonia. Besides, two species present apparently more restricted, unique distributions. Only three species have a distribution that is congruent with one of the areas of endemism (AE) recognized for other organisms (birds and primates), of which two occur in AE Guiana and one in AE Inambari.

Brazilian Bioluminescent Beetles: Reflections on Catching Glimpses of Light in the Atlantic Forest and Cerrado

Directory of Open Access Journals (Sweden)

ETELVINO J.H. BECHARA

Full Text Available ABSTRACT Bioluminescence - visible and cold light emission by living organisms - is a worldwide phenomenon, reported in terrestrial and marine environments since ancient times. Light emission from microorganisms, fungi, plants and animals may have arisen as an evolutionary response against oxygen toxicity and was appropriated for sexual attraction, predation, aposematism, and camouflage. Light emission results from the oxidation of a substrate, luciferin, by molecular oxygen, catalyzed by a luciferase, producing oxyluciferin in the excited singlet state, which decays to the ground state by fluorescence emission. Brazilian Atlantic forests and Cerrados are rich in luminescent beetles, which produce the same luciferin but slightly mutated luciferases, which result in distinct color emissions from green to red depending on the species. This review focuses on chemical and biological aspects of Brazilian luminescent beetles (Coleoptera belonging to the Lampyridae (fireflies, Elateridae (click-beetles, and Phengodidae (railroad-worms families. The ATP-dependent mechanism of bioluminescence, the role of luciferase tuning the color of light emission, the “luminous termite mounds” in Central Brazil, the cooperative roles of luciferase and superoxide dismutase against oxygen toxicity, and the hypothesis on the evolutionary origin of luciferases are highlighted. Finally, we point out analytical uses of beetle bioluminescence for biological, clinical, environmental, and industrial samples.

Full Text Available This paper presents the results of an exploratory, inductive cataloguing of the views of Brazilian and U.S. academics regarding current leadership theory and development. Semi structured interviews with academics from a variety of institutional settings in Brazil and the U.S. were content analyzed to identify major themes and tendencies across the two countries. Our analyses revealed that neither Brazilian nor U.S. academics adopted the bulk of current formal leadership thought uncritically. Instead, both the Brazilian and North American business education fields adopted theories selectively and formulated idiosyncratic approaches to the field. The U.S. interviewees appeared to vary much more from one another than the Brazilian scholars, whose positions were more critical but more homogeneous overall. There was also considerable variation across the two national settings. We found Bourdieu’s practice theory useful in interpreting our results, particularly the concepts of field differentiation and heteronomy, habitus, and cultural capital. Still, much research remains to be done to disentangle the purely historical and cultural factors from the impacts of the social construction of the field of business education in the two countries.

Methodological study that aimed to adapt the Satisfaction with Appearance Scale (SWAP) into Brazilian Portuguese language and to assess the validity, the reliability and the dimensionality of the adapted version in a sample of Brazilian burn victims. We carried out the adaptation process according to the international literature. Construct validity was assessed by correlating the adapted version of SWAP scores with depression (Beck Depression Index), self-esteem (Rosenberg Self-Esteem Scale), health-related quality of Life (Short Form Health Survey-36) and health status of burn victims (Burn Specific Health Scale-Revised), and with gender, total body surface area burned, and visibility of the scars. We tested dimensionality using Exploratory Factor Analysis (EFA) and the reliability by means of Cronbach's alpha. Participants were 106 adult burned patients. The correlations between the Brazilian version of the SWAP scores and the correlated construct measures varied from moderate to strong (r=.30-.77). The participants who perceived their burn sequelae was visible reported being more dissatisfied with their body image than the participants who answered that their scars would not be visible (preliable for use with Brazilian burn victims.

The regimes of accountability, the organizations of global governance and institutional arrangements of global governance of nuclear non-proliferation and of Mutual Vigilance Brazilian-Argentine of Nuclear Safeguards are the subject of research. The starting point is the importance of the institutional model of global governance for the effective control of non-proliferation of nuclear weapons. In this context, the research investigates how to structure the current arrangements of the international nuclear non-proliferation and what is the performance of model Mutual Vigilance Brazilian-Argentine of Nuclear Safeguards in relation to accountability regimes of global governance. For that, was searched the current literature of three theoretical dimensions: accountability, global governance and global governance organizations. In relation to the research method was used the case study and the treatment technique of data the analysis of content. The results allowed: to establish an evaluation model based on accountability mechanisms; to assess how behaves the model Mutual Vigilance Brazilian-Argentine Nuclear Safeguards front of the proposed accountability regime; and to measure the degree to which regional arrangements that work with systems of global governance can strengthen these international systems.

International orientation and export commitment in fast small and medium size firms internationalization: scales validation and implications for the Brazilian case

Directory of Open Access Journals (Sweden)

Marcelo André Machado

Full Text Available Abstract A set of changes in the competitive environment has recently provoked the emergence of a new kind of organization that has since its creation a meaningful share of its revenue being originated from international activities developed in more than one continent. Within this new reality, the internationalization of the firm in phases or according to its growth has resulted in it losing its capacity to explain this process with regard to small- and medium-sized enterprises (SME. Thus, in this paper, the international orientation (IO and export commitment (EC constructs have been revised under a theoretical context of the fast internationalization of medium-sized companies, so as to identify scales that more accurately measure these dimensions in the Brazilian setting. After a literature review and an exploratory research, the IO and EC scales proposed by Knight and Cavusgil (2004 and Shamsuddoha and Ali (2006 were respectively applied to a sample of 398 small- and medium-sized exporting Brazilian companies. In spite of conjunction and situation differences inherent to the Brazilian companies, the selected scales presented high measuring reliability. Furthermore, the field research outcomes provide evidence for the existence of a phenomenon of fast internationalization in medium-sized companies in Brazil, as well as support some theoretical assumptions of other empirical investigations carried out with samples from developed countries.

2013-12-01

Full Text Available The purpose of this paper is to reflect about the contours that the discussion about the audience on the webjournalism is gaining. Our search is for the perception of brazilian researchers regarding this topic. How is the experience of the audience in the world wide web observed, analyzed and reported by brazilian researchers? To answer this question, we seek scientific studies published from 2005 to 2011 in the seven top journals evaluated by Qualis, a system of the Brazilian institution Capes. A sample of 30 papers led us to conclude that most of the analyzed scientific productions were dedicated to effectively discuss the theme of the audience. Other aspects about journalism that could arouse interest are relegated to the background while the prevailing discussion is bout the new scenery of audience, which, according to the authors studied, changed deeply with the advent of the Internet.

Refuting feminism: Brazilian lettered culture's complacency/complicity

Directory of Open Access Journals (Sweden)

Rita Terezinha Schmidt

Full Text Available In appraising the power of antifeminist discourse in Brazil, I examine how this discourse appears in the realm of cultural journalism in order to make some connections to Brazilian social history, in the light of which it may be possible to understand why feminism as transforming praxis seems so alien to the habits of the country. To sustain my arguments I draw on the readings of Brazilian historical and cultural thinkers considered "leftists". At the same time, I point out the limits of their analyses, that is, their silence regarding women's oppression and gender issues. Finally, I examine the persistence of various forms of antifeminism in the lettered milieu so as to understand the statute of feminist critique in the field of literary studies and the reasons for its invisibility, including considerations on its achievements and the limitations of its practices.

Full Text Available The objective of this study was to describe the Brazilian scientific reports published over the past twenty years on Fournier’s gangrene. It is an integrative review conducted through incursions in the LILACS, MEDLINE, BDENF and Coleciona SUS databases with the descriptor ‘Fournier’s Gangrene’. Texts published between January 1994 and July 2014, in Portuguese, and freely available online were selected. According to the 14 articles found, the main symptoms of Fournier’s gangrene include discomfort with painful sensations, high fever, edema, malaise, and sweating. In most cases erythema and blistering are observed, evolving into a wound. The clinical profile assists in the selection of empirical antimicrobial therapy even before the culture results. It was concluded that early diagnosis and appropriate and aggressive treatment are crucial in patient prognosis. There is still a shortage of Brazilian scientific production with a high power of evidence on the subject.

Full Text Available Objective. The aim of this study was to evaluate the psychometric properties of the Brazilian version of the Dental Fear Survey (DFS, previously translated to the Brazilian Portuguese language and validated. Methods. A cross-sectional study with 1,256 undergraduates from the city of Belo Horizonte, Brazil, was carried out. The DFS and a questionnaire about previous dental experiences were self-administered. Data analysis involved descriptive statistics, principal components analysis (PCA, confirmatory factor analysis (CFA, internal consistency and test-retest reliability, and construct, discriminant, and convergent validity. Results. PCA identified a three-factor structure. CFA confirmed the multidimensionality of the Brazilian version of the DFS. A modified model of the Brazilian version of the DFS fits better than the hypothesized model. The Cronbach’s alpha coefficient for the total DFS scale was 0.95. Conclusion. The DFS demonstrated acceptable construct validity, convergent validity, and discriminant validity. These results supported the reliability and validity of the DFS among Brazilian undergraduates.

The Brazilian Pampa: A Fragile Biome

Valdir Marcos Stefenon

2009-12-01

Full Text Available Biodiversity is one of the most fundamental properties of Nature. It underpins the stability of ecosystems, provides vast bioresources for economic use, and has important cultural significance for many people. The Pampa biome, located in the southernmost state of Brazil, Rio Grande do Sul, illustrates the direct and indirect interdependence of humans and biodiversity. The Brazilian Pampa lies within the South Temperate Zone where grasslands scattered with shrubs and trees are the dominant vegetation. The soil, originating from sedimentary rocks, often has an extremely sandy texture that makes them fragile—highly prone to water and wind erosion. Human activities have converted or degraded many areas of this biome. In this review we discuss our state-of-the-art knowledge of the diversity and the major biological features of this regions and the cultural factors that have shaped it. Our aim is to contribute toward a better understanding of the current status of this special biome and to describe how the interaction between human activities and environment affects the region, highlighting the fragility of the Brazilian Pampa.

This study was carried out in the Brazilian southern Amazon region (Rondonia state and Humaita, southern Amazon state). Carbon isotope data on soil organic matter have been collected along an ecosystem transect of about 750 km that includes a savanna, a wooded savanna (cerrado), a tropical semideciduous forest (cerradao), a forest transition type and a tropical forest. The main objective is to evaluate the expansion-regression dynamics of these vegetation units in relation to climate changes during the Late Pleistocene (Late Glacial) and Holocene. Large ranges in δ 13 values were observed in soil organic matter collected from profiles in the savanna (-27 to -14 per mille and forest regions (-26 to -19 per mille) reflecting changing distribution of 13 C-depleted C 3 forest and 13 C enriched C 4 savanna vegetation in response to climate change. 14 C data of humin fraction and buried charcoal indicate that the organic matter in these soils is at least 17,000 years BP at 300-cm depth. In this period, the entire ecosystem transect are characterized by δ 13 C soil depth profiles, generated typically by C 3 plants (forest), inferring a humid climate in the southern Amazon region after the end of last glaciation. 13 C data also indicate that C 4 plants (grasses) have influenced significantly the vegetation at the transitional forest and the cerrado sites of southern Rondonia state and two distinct points in the forest ecosystem in the southern Amazon state. These typical C 4 type isotopic signatures probably reflect a drier climate during about 9000-8000 yr BP to 3000 yr BP and the savanna and wooded savanna expansion in distinct points of the transect. The 13 C records representing the 3000 yr show an expansion of the forest, due to a climatic improvement, in areas previously occupied by savanna vegetation. This study adds to the mounting evidence that extensive forested areas existed in the Amazon during the last glacial and that savanna vegetation expanded in response

International Astronomical Search Collaboration (IASC) is an international educational project between universities, schools, observatories and research institutions. Its main objective is to enroll high school and college students in the monitoring and discovery of asteroids and Near Earth Objects (NEOs), especially Potentially Hazardous Asteroids. The methodology consists in the analysis of astronomical images obtained in several observatories in North America and Hawaii. The images are distributed throughout the school network and the results must be delivered in a 72-hour timeframe. Since 2010 Brazilian universities and schools have joined IASC, resulting in over a dozen new asteroids found (3 of them NEOs), and hundreds of measurements for already known asteroids. A major event in this collaboration was the All-Brazil Asteroid Search Campaign, which was conducted in September 2012. 2013 marks the fourth year of Brazilian participations in IASC, with one important milestone: the third straight appearance of a Brazilian institution in the Pan-STARRS campaign, which uses the PS1 telescope in Haleakala, Hawaii. We will present a summary of the overall results, as well as the latest news from 2013 campaigns. We will discuss the impact promoted by the past events, such as how the interest in astronomy changed before and after the campaigns, and it has helped the students to choose their future careers.

2000-01-01

Full Text Available OBJECTIVE: To report about a group of physicians' understanding of the recommendations of the II Brazilian Guidelines Conference on Dyslipidemias, and about the state of the art of primary and secondary prevention of atherosclerosis. METHODS: Through the use of a questionnaire on dyslipidemia, atherosclerosis prevention, and recommendations for lipid targets established by the II Brazilian Guidelines Conference on Dyslipidemias, 746 physicians, 98% cardiologists, were evaluated. RESULTS:Eighty-seven percent of the respondents stated that the treatment of dyslipidemia changes the natural history of coronary disease. Although most of the participants followed the total cholesterol recommendations (<200mg/dL for atherosclerosis prevention, only 55.8% would adopt the target of LDL-C <100 mg/dL for secondary prevention. Between 30.5 and 36.7% answered, in different questions, that the recommended level for HDL-C should be <35mg/dL. Only 32.7% would treat their patients indefinitely with lipid- lowering drugs. If the drug treatment did not reach the proposed target, only 35.5% would increase the dosage, and 29.4% would change the medication. Participants did not know the targets proposed for diabetics. CONCLUSION: Although the participating physicians valued the role played by lipids in the prevention of atherosclerosis, serious deficiencies exist in their knowledge of the recommendations given during the II Brazilian Guidelines Conference on Dyslipidemias.
