    An analyzer-based X-ray phase-contrast imaging (ABI) setup has been mounted at the Brazilian Synchrotron Light Laboratory (LNLS) for multiple imaging radiography (MIR) purposes. The algorithm employed for treating the MIR data collected at LNLS is described, and its reliability in extracting the distinct types of contrast that can be obtained with MIR is demonstrated by analyzing a test sample (thin polyamide wire). As a practical application, the possibility of studying ophthalmic tissues, corneal sequestra in this case, via MIR is investigated.

    Full text: The LNLS is operational since 1997 and has a second-generation light source with a 1,37GeV electron storage ring and 2,08 keV critical energy. Besides the storage ring there are various beamlines installed mainly in magnetic dipoles, however were opened three beamlines based in insertion devices, wiggler and undulator. The LNLS is now operating with 16 beamlines which are open to the external user community: 9 of them are dedicated to structural studies and the other 7 to spectroscopic techniques. The beamlines devoted to structural studies involve X-ray diffraction (XRD1, XRD2, XPD and XDS), small-angle X-ray scattering (SAXS1 and SAXS2), protein crystallography (MX1 and MX2) and X-ray fluorescence (XRF). The beamlines dedicated to spectroscopic studies are X-ray absorption fine structure (XAFS1, XAFS2 and DXAS), soft X-ray spectroscopy (SXS), spherical grating monochromator (SGM), plane grating monochromator (PGM) and toroidal grating monochromator (TGM). Two more beamlines are expected to begin their operation in 2012: X-ray tomography and infrared spectroscopy. Each beamline has its own characteristics in terms of photon energy range, flux, resolution and beam size, but many of the optical elements and instrumentation are common to various beamlines and the main are mirrors, monochromators (crystal and diffraction grating), slits and filters. For X-ray and VUV spectroscopy, several experimental techniques can be explored including XAS, XMCD, XMLD, XPS, AES, UPS, XEOL, reflectivity and PePiCo. For that, these beamlines share different end stations and instrumentation that can be easily installed and commissioned for attend a specific experiment. (author)

    XRD1 was the first X-ray diffraction beamline to be built at the LNLS and after approximately 12 years of operation it was substantially updated to improve beam stability, increase the reliability of the monochromator movement as well as provide an experimental hutch that would meet the demands of users. The improvements included the construction of an independent concrete slab below the mirror and monochromator to minimize the vibrations originating from the floor. In addition, the installation of new monochromator mechanisms as well as the replacement of the two Si(111) crystals were performed in order to attain higher precision, stability and reproducibility during operation. Moreover, the diffractometer was replaced by a 3-circle heavy duty diffractometer from Newport to collect XRD patterns primarily in capillary geometry. A robotic arm was installed for fast and automated replacement of samples as well as to secure a cryojet or a hot air blower in front of the sample during measurements. In addition, a housing equipped with 24 Mythen detectors was installed at the beamline allowing for extremely fast data acquisition. Another upgrade was the integration of motors and control systems from PXI National Instruments and Galil controllers with Phytron. These systems are crucial for the next upgrade that is underway at the beamline: enabling remote access for users to collect their measurements without the need to travel to the LNLS.

    A new beamline, fully dedicated to X-ray powder diffraction (XPD) measurements, has been installed after the exit port B of the bending magnet D10 at the Brazilian Synchrotron Light Laboratory (LNLS) and commissioned. The technical characteristics of the beamline are described and some performance indicators are listed, such as the incoming photon flux and the angular/energy resolutions obtainable under typical experimental conditions. The results of a Rietveld refinement for a standard sample of Y2O3 using high-resolution data are shown. The refined parameters match those found in the literature, within experimental error. High-resolution XPD measurements on Ba2FeReO6 demonstrate a slight departure from the ideal cubic double-perovskite structure at low temperatures, not detected by previous powder diffraction experiments. The onset of the structural transition coincides with the ferrimagnetic ordering temperature, Tc approximately equal to 315 K. Subtle structural features, such as those reported here for Ba2FeReO6, as well as the determination and/or refinement of complex crystal structures in polycrystalline samples are ideal candidate problems to be investigated on this beamline.

    Full text: Instrumentation recently developed at the SAXS beamline of the LNLS has made possible the study of several interesting experiments with real-time data collection. A WAXS-SAXS chamber which allows the simultaneous recording of wide and small angle scattering, has been an ideal instrument for the study of polymer samples during temperature -controlled experiments. In this instrument, temperature can be varied from -4 to 95 deg C and has been used with specific sample holders for the study of the crystallization of amorphous metallic ribbons by Joule heating. Sealed sample holders for liquids operated under controlled temperature have been used successfully in the study of complex fluid systems, for in situ measurements of structural phase transitions. The sample temperature can be varied between -6 and 90 deg C or between room temperature and 170 deg C. A very small volume of sample is necessary and the scattering patterns are registered with very low background and excellent reproducibility. A newly developed high temperature chamber for simultaneous recording of WAXS and SAXS spectra during thermal treatment, operates from room temperature up to 1000 deg C in vacuum, and has proved to be very successful in the study of nucleation and growth of nano crystals in glassy matrices as well as crystallization of polymer blends. Several examples of these applications will be presented. (author)

    The majority of the beamlines at the Brazilian Synchrotron Light Source Laboratory (LNLS) use radiation produced in the storage-ring bending magnets and are therefore currently limited in the flux that can be used in the harder part of the X-ray spectrum (above ∼10 keV). A 4 T superconducting multipolar wiggler (SCW) was recently installed at LNLS in order to improve the photon flux above 10 keV and fulfill the demands set by the materials science community. A new multi-purpose beamline was then installed at the LNLS using the SCW as a photon source. The XDS is a flexible beamline operating in the energy range between 5 and 30 keV, designed to perform experiments using absorption, diffraction and scattering techniques. Most of the work performed at the XDS beamline concentrates on X-ray absorption spectroscopy at energies above 18 keV and high-resolution diffraction experiments. More recently, new setups and photon-hungry experiments such as total X-ray scattering, X-ray diffraction under high pressures, resonant X-ray emission spectroscopy, among others, have started to become routine at XDS. Here, the XDS beamline characteristics, performance and a few new experimental possibilities are described.

    Phosphorus is an essential nutrient for plant growth. Million of tones of P are applied to the soils annually. However, only a small fraction of the P applied with fertilizers is taken up by crops in the year of application, and the effectiveness of any residual P fertilizer declines with time. To improve our understanding of the mechanisms underlying this response to P in the field, we have studied the mobility of P from 3 different fertilizes: monoammonium phosphate (MAP), polymer coated monoammonium phosphate (MAPp) and Organomineral phosphate (OMP) applied on high weathered soil samples in a Petri dish experiment. Total Reflection X-Ray Fluorescence (TXRF) was used to determine the P diffusive flux at different distances (0 - 7.5, 7.5 – 13.5, 13.5 – 25.5 and 25.5 – 43 mm) from granular fertilizer. TXRF analyses were performed at the X-Ray Fluorescence Beamline D09B at Brazilian National Synchrotron Light Laboratory (LNLS), in Campinas, Sao Paulo, using a polychromatic beam with maximum energy of 20 keV for the excitation and an Ultra-LEGe detector with resolution of 148 eV at 5.9 keV. Besides that, the detections were performed in a high vacuum chamber (2.5 x 10-5 mbar) to avoid air absorption. After a period of five weeks, the total P concentration increased in the soil sampled 7.5 to 13.5 mm from the fertilizer showing a diffusive flux of P. About 20% (considering MAP and MAPp) of the total P applied diffused out of the central soil ring. Different sources showed differences in diffusive flux of P. Soil pH also influenced diffusive flux of P showing higher flux on lower pH soils. (author)

    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 objective of Brazilian Eratosthenes Project is the development and application of teaching training actions according the ``docent autonomy" concept to basic Astronomy Education. Argentina coordinates the project in South America, but Brazil works in this project since 2010 with the theme ``Projeto Eratóstenes Brasil" in the homepage: http://sites.google.com/site/projetoerato. Two schools measure a sticks shadow and communicate their results. After, they calculate an average radius of Earth. The stick (gnomon) should stay in vertical position in the leveled ground. Since 2010, the project received hundreds of Brazilian schools with different experiments that were constructed with autonomy, because our site doesn't show some itinerary pre-ready to elaborate the experiments. To collect data for our research, we will use interviews via Skype with the teachers. These data are useful to researches about Science Education area and the Teaching Formation. Teaching professional practice could change and we see modifications in the teachers work, what depends of their realities and context. This project intents to respect the docent autonomy. This autonomy to responsible modifications during continued formation is called ``activist formative model" according Langhi & Nardi (Educação em Astronomia: repensando a formação de professores. São Paulo: Escrituras Editora, 2012). This project discusses about researches in Astronomy Education - still extreme rare in Brazil, when we compare with other areas in Science Education. We believe that actions like this could motivate the students to learn more Astronomy. Furthermore, this national action can be a rich source of data to investigations about teaching formation and scientific divulgation.

    Full Text Available This paper provides an evaluation of schooling inequality in Brazil using different indicators such as the Education Gini coefficient, the Education Standard Deviation and the Average number of Years of Schooling. We draw up a statistical description of Brazilian human capital dispersion in time over the last half century, across regions and states. Our analysis suggests several conclusions: 1 Strong reduction of educational inequalities measured by Education Gini index. 2 A three parts picture of Brazil seems to emerge, reflecting initial conditions. 3 High increase of the Average number of Years of Schooling. 4 A significant link between Education Gini and the average education length. 5 Education Standard Deviation leads to inverted results compared to Education Gini. 6 Brazilian data are consistent with an Education Kuznets curve if we consider Education Standard Deviation.Esse trababalho busca avaliar o grau de desigualdade educacional no Brasil baseado-se em diferentes indicatores tais como: o índice de Gini educacional, os anos médios de escolaridade e no desvio padrão educacional.

    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.

    2012-09-01

    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.

    We report on an important advance for the vacuum ultraviolet and soft X-ray TGM beamline at Laboratorio Nacional de Luz Sincrotron (LNLS). This beamline provides photons in the energy range 12-330 eV using three gratings. It is well known that TGMs deliver relatively high flux at these energies but harmonic contamination can be a serious problem. Of special interest for the users is the range between 12 and 21 eV covered by one of the gratings for studies of outer and inner valence ionization processes in gases as well as solids. Here, we report a solution to the harmonic contamination problems based on a noble gas phase filter combined with thin metal foil barriers.

    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

    This work studies the Zipf Law for cities in Brazil. Data from censuses of 1970, 1980, 1991 and 2000 were used to select a sample containing only cities with 30,000 inhabitants or more. The results show that the population distribution in Brazilian cities does follow a power law similar to the ones found in other countries. Estimates of the power law exponent were found to be 2.22 +/- 0.34 for the 1970 and 1980 censuses, and 2.26 +/- 0.11 for censuses of 1991 and 2000. More accurate results were obtained with the maximum likelihood estimator, showing an exponent equal to 2.41 for 1970 and 2.36 for the other three years.

    2017-01-01

    This study aimed to develop and validate a Brazilian version of the Food Craving Inventory (FCI-Br), adapted to the cultural-gastronomic context of Brazil, and to explore this behavior among adult Brazilians. The Study 1 population consisted of 453 adults from all regions of Brazil. Participants responded to a preliminary form of the instrument online. Exploratory factor analysis revealed an FCI-Br presenting 23 items and three factors: High Fat, Sweet Food and Traditional Meal. The FCI-Br overall reliability was considered adequate (α = 0.82), as were each of the sub-scales. The food items receiving higher average scores from the application of the instrument were chocolate (3.14 ± 1.28; women) and bread (2.94 ± 1.44, men). A significant association was observed between the specific-craving for Sweet Food and female respondents. Most participants reported experiencing more frequent episodes of food craving when alone (68.0%; n = 391) and during the afternoon (32.2%; n = 127) or evening (43.8%; n = 173) hours. Application of the FCI-Br in a population of 649 university students (Study 2) demonstrated a good adjustment of the model developed according to the Confirmatory factor analysis (χ(2)/gl = 2.82, CFI = 0.94; TLI = 0.93; RMSEA = 0.06). The current findings indicate that the FCI-Br has adequate psychometric properties to measure craving behavior with respect to specific food groups in the resident population of Brazil. The results of this study also shed light on the importance of considering the cultural diversity of a population when investigating eating behaviors.

  3. 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 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 The permeability of Brazilian Eucalyptus grandis and Eucalyptus citriodora wood was measured in a custom build gas analysis chamber in order to determine which species could be successfully treated with preservatives. Liquid permeability was tested using an emulsion of Neen oil and a control of distillated water. Air was used to test the gas phase permeability. For both Eucalyptus grandis and Eucalyptus citriodora, the longitudinal permeability of gas was shown to be about twice as great as the liquid phase permeability. No radial permeability was observed for either wood. The permeability of air and water through the sapwood of Eucalyptus grandis was greater than that through the sapwood of Eucalyptus citriodora. The permeability of neen oil preservative through the sapwood of Eucalyptus grandis was also greater than through the sapwood of E. Citradora, but the difference was not statistically significant. Scanning Electron Microscopy images showed that the distribution and obstruction in the vessels could be correlated with observed permeability properties. Irrespective of the causes of differences in permeability between the species, the fluid phase flux through the sapwood of both species was significant, indicating that both Eucalyptus grandis and Eucalyptus citriodora could be successfully treated with wood preservative.

  7. Educating Brazilian workers about AIDS.

    1991-12-01

    This article contains a the script for a slide-tape presentation entitled Working Against AIDS, a presentation developed by the Brazil Family Planning Association (BEMFAM) which is designed to debunk common misconceptions about the disease. This audio-visual, which targets Brazilian workers, can be used during talks, seminars, and meetings. A discussion of the issues involved usually follows the presentation of Working Against AIDS. The presentation contains 30 illustrated slides (these are included in the article). The presentation begins by explaining that much of the information concerning AIDS is prejudicial and misleading. The next few slides point out some of the common misconceptions about AIDS, such as claims denying the existence of the disease, or suggestions that only homosexuals and prostitutes are at risk. The presentation then goes on to explain the ways in which the virus can and cannot be transmitted. Then it discusses how the virus destroys the body's natural defenses and explains the ensuing symptoms. Slides 14 and 15 point out that no cure yet exists for AIDS, making prevention essential. Slides 16-23 explain what actions are considered to be high risk and which ones do not entail risk. Noting that AIDS can be prevented, slide 24 says that the disease should not present an obstacle to spontaneous manifestations of human relations. The next slide explains that condoms should always be used when having sex with someone who could be infected with AIDS. Finally slides 26-30 demonstrate the proper way to use and dispose of a condom.

    In response to an alarming rise in human immunodeficiency virus (HIV) infection among Brazilian women during the early 1990s, the Sociedade Civil Bem-Estar Familiar no Brazil (BEMFAM) developed a project that integrates HIV prevention with clinical services, community-based prevention activities, and sexually transmitted disease diagnosis and treatment. Preliminary interviews with clinic clients revealed that women's fears they would be considered unfaithful were impeding their ability to suggest condom use to their sexual partners. Condom use within a relationship was considered appropriate only for pregnancy prevention. To facilitate dialogue about sexual health, BEMFAM developed a women's group intervention project. All women who attend a BEMFAM clinic are invited to participate in a one-hour group discussion before receiving medical services. Novela-style booklets with stories and characters women can relate to their own lives are used to stimulate discussion. Participants learn to use condoms correctly by putting them on a penis model and anticipate situations in which they would be able to negotiate condom use. The group setting enables women to gain confidence and practice assertiveness in a non-threatening, supportive environment. Their identification with other women's stories empowers women to take control of their health and sexual lives. Between October 1994 and July 1995, 3464 women participated in group discussions organized by BEMFAM and 40,688 condoms were distributed; 18% of these women returned to the clinic for additional condoms.

    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.

Two persons proficient in English independently translated the original scale into Brazilian-Portuguese and a consensus version was generated. Two translators performed a back translation. Discrepancies were discussed and solved by a panel. Forty patients older than 65 years and 40 therapists were included in the cultural adaptation phase. If more than 15% of therapists or patients reported difficulty in understanding an item, that item was reformulated and reapplied. The final Brazilian version was then tested on 36 elderly patients (over age 65). The average age was 72 years. Reliability of the measure was assessed twice by one physical therapist (1-week interval between assessments) and once by one independent physical therapist. Descriptive analysis was used to characterize the patients. The intraclass correlation coefficient (ICC) and Pearson's correlation coefficient were computed to assess intra- and interobserver reliability. Six questions were modified during the translation stage and cultural adaptation phase. The ICC for intra- and interobserver reliability was 0.99 (P Berg balance scale is a reliable instrument to be used in balance assessment of elderly Brazilian patients.

    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)

    Full Text Available Huntington disease (HD is associated with expansions of a CAG trinucleotide repeat in the HD gene. Accurate measurement of a specific CAG repeat sequence in the HD gene in 92 Brazilian controls without HD, 44 Brazilian subjects with clinical findings suggestive of HD and 40 individuals from 6 putative HD families, showed a range from 7 to 33 repeats in normal subjects and 39 to 88 repeats in affected subjects. A trend between early age at onset of first symptoms and increasing number of repeats was seen. Major increase of repeat size through paternal inheritance than through maternal inheritance was observed. Data generated from this study may have significant implications for the etiology, knowledge of the incidence, diagnosis, prognosis, genetic counseling and treatment of HD Brazilian patients.

    The aim of this study was to examine the applicability of a Brazilian version of the Self-consciousness Scale to university students. Factorial structure, subscale intercorrelations, and normative data obtained with 182 subjects are reported. These results suggest that the proposed model of self-consciousness is applicable in the Brazilian culture, although some significant sex differences were found for two of the scales. Reliability tests and the factorial validity of the scale showed that this version still needs refinement to be used as a reliable research tool.

    Climate Change, Impacts and Vulnerabilities in Brazil: Preparing the Brazilian Northeast for the Future; Natal, Brazil, 27 May to 01 June 2012 The variability of the semiarid climate of the Brazilian northeast has enormous environmental and social implications. Because most of the population in this area depends on subsistence agriculture, periods of severe drought in the past have caused extreme poverty and subsequent migration to urban centers. From the ecological point of view, frequent and prolonged droughts can lead to the desertification of large areas. Understanding the causes of rainfall variability, in particular periods of severe drought, is crucial for accurate forecasting, mitigation, and adaptation in this important region of Brazil.

    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.

    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.

    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.

    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

    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.

    2013-12-01

    Full Text Available Agroforestry systems for animal husbandry in Brazil, including integrated crop-livestock-forest systems (ICLF, are very diverse, and present several technical, environmental and socio-economic benefits. For each of the country’s 5 regions (Southeast, Central-West, North, Northeast and South the prevailing agroforestry systems holding animals are presented, their potential and constraints discussed and research needs identified. In general, such systems are not broadly adopted, mainly because of their level of complexity compared with traditional systems, as well as some lack of understanding by farmers regarding their benefits. To change this situation, in the last 5 years, the Brazilian Government has allocated financial resources in terms of credit for development as well as for research and technology transfer addressing ICLF systems, including good agricultural practices and mitigation of greenhouse gas emissions. The goal is to improve competitiveness of the Brazilian agribusiness sector.

    Full Text Available We study the interaction between forward and spot electricity markets in a scenario where buyers and sellers are price takers in the forward market and trade through marketers, who play a Cournot game. Our model’s main features come from the Brazilian electricity market, where a free contract market coexists with a regulated contract market, and the spot price is the output of a stochastic dynamic algorithm. We are able to show that the price of energy bought (sold forward decreases (increases with the number of marketers, and that, as a result, full hedging is achieved in the limit. We also investigate the effects on prices of changes in the number of market participants and in aggregate consumption and supply, an exercise that yields important policy recommendations for the Brazilian regulator.

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.

    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.

    Full Text Available OBJECTIVE: The majority of cases of hepatocellular carcinoma have been reported in individuals with cirrhosis due to chronic viral hepatitis and alcoholism, but recently, the prevalence has become increasingly related to nonalcoholic steatohepatitis around the world. The study aimed to evaluate the clinical and histophatological characteristics of hepatocellular carcinoma in Brazilians' patients with nonalcoholic steatohepatitis at the present time. METHODS: Members of the Brazilian Society of Hepatology were invited to complete a survey regarding patients with hepatocellular carcinoma related to nonalcoholic steatohepatitis. Patients with a history of alcohol intake (>20 g/day and other liver diseases were excluded. Hepatocellular carcinoma diagnosis was performed by liver biopsy or imaging methods according to the American Association for the Study of Liver Diseases’ 2011 guidelines. RESULTS: The survey included 110 patients with a diagnosis of hepatocellular carcinoma and nonalcoholic fatty liver disease from nine hepatology units in six Brazilian states (Bahia, Minas Gerais, Rio de Janeiro, São Paulo, Paraná and Rio Grande do Sul. The mean age was 67±11 years old, and 65.5% were male. Obesity was observed in 52.7% of the cases; diabetes, in 73.6%; dyslipidemia, in 41.0%; arterial hypertension, in 60%; and metabolic syndrome, in 57.2%. Steatohepatitis without fibrosis was observed in 3.8% of cases; steatohepatitis with fibrosis (grades 1-3, in 27%; and cirrhosis, in 61.5%. Histological diagnosis of hepatocellular carcinoma was performed in 47.2% of the patients, with hepatocellular carcinoma without cirrhosis accounting for 7.7%.

    This special issue includes invited and selected articles of the VIIth Brazilian Meeting on Simulational Physics (BMSP), held in João Pessoa, Paraíba, Brazil, from the 5th to 10th August, 2013. This is the seventh such meeting, and the first one to have contributed papers published in the Journal of Physics: Conference Series. The previous meetings in the BMSP series took place in the mountains of Minas Gerais and in the region of the Brazilian Pantanal. Now, for the first time, the Meeting was held in the pleasant shores of João Pessoa, the capital of the Paraíba state. The VIIth BMSP brought together more than 50 researchers from all over the world for a vibrant and productive period. As in the previous meetings, the talks and posters highlighted recent advances in applications, algorithms, and implementations of computer simulation methods for the study of condensed matter, materials, out of equilibrium, quantum and biologically motivated systems. We are sure that this meeting series will continue to provide a valuable venue for people working in simulational physics to exchange ideas and discuss the state of art of this always expanding field. We are very glad to realize this special issue, and are most appreciative to the editors of the Journal of Physics: Conference Series for making this publication possible. We are grateful for the outstanding work of the João Pessoa team, for the financial support of the Brazilian agencies CNPq, CAPES, FAPESQ, and of the Federal Universities UFPB and UFMG. At last, but not least, we would like to acknowledge all of the authors of this special issue for their contributions. João Antonio Plascak Alexandre Rosas Guest Editors Conference photograph

    The aim of this study was to evaluate the adequacy of the Brazilian legislation about fluoride toothpaste. A search was conducted in LILACS, Medline and SciELO databases about the fluoride concentration found in Brazilians toothpastes, using descriptors on health. Publications since 1981 have shown that some Brazilian toothpastes are not able to maintain, during their expiration time, a minimum of 1,000 ppm F of soluble fluoride in the formulation. However, the Brazilian regulation (ANVISA, Resolution 79, August 28, 2000) only sets the maximum total fluoride (0.15%; 1,500 ppm F) that a toothpaste may contain but not the minimum concentration of soluble fluoride that it should contain to have anticaries potential, which according to systematic reviews should be 1,000 ppm F. Therefore, the Brazilian regulation on fluoride toothpastes needs to be revised to assure the efficacy of those products for caries control.

    Brazilian keratin treatments are widely available products that are used by women all over the world to straighten hair. Marketers of these products claim that the keratin treatments render naturally curly hair more manageable and frizz-free while enhancing color and shine, giving the hair a healthier appearance. Although widely used, there have been virtually no reports of adverse side effects. Unfortunately, many of the products that are applied by salon professionals contain formaldehyde or its derivatives and are being marketed as safe.

    1. Plasma concentrations of cholesterol, cholesteryl esters, phospholipids and triglycerides were determined for ten species of Brazilian lizards, Iguana iguana, Tropidurus torquatos and T. semitaeniatus (Iguanidae), Tupinambis teguixin, Ameiva ameiva and Cnemidophorus ocellifer (Teiidae), Mabuya maculata (Scincidae), Hemidactylus mabouia (Gekkonidae), Amphisbaenia vermicularis and Leposternon polystegum (Amphisbaenidae). 2. Considerable inter- and intra-species variations in plasma lipid concentrations were observed. 3. The percentage of total cholesterol esterified and the individual phospholipid composition of plasma were relatively constant for each species. 4. Over 60% of the cholesteryl esters present in plasma from three species each of iguanid and teiid lizards were polyenoic.

    2009-09-01

    In Brazil most Construction and Demolition Waste (C&D waste) is not recycled. This situation is expected to change significantly, since new federal regulations oblige municipalities to create and implement sustainable C&D waste management plans which assign an important role to recycling activities. The recycling organizational network and its flows and components are fundamental to C&D waste recycling feasibility. Organizational networks, flows and components involve reverse logistics. The aim of this work is to introduce the concepts of reverse logistics and reverse distribution channel networks and to study the Brazilian C&D waste case.

  1. The Brazilian deindustrialization: financialization is not guilty

    2015-06-01

    Full Text Available The financialization of the Brazilian economy is often criticized as being responsible of the slowdown of capital accumulation in this country. Indeed, very high interest rates are maintained in order to finance the public debt, and this fosters capitalists to get more Treasury bonds rather than to invest in the productive area. Nevertheless, the evolution of the profit rate in this area also explains the particular relation existing between capitalists, finance and productive investment, as Marx showed it more than a century ago.

    Full Text Available This paper relies on some data to identify the 19th century as the major period in which Brazil economy lagged behind some chosen benchmarking countries, as the USA, Canada, New Zealand, Australia and some European periphery countries. To identify the reasons for this an exercise using immigration data was used to make a decomposition of the sources of growth of the proportion of the USA per capita GDP to the Brazilian one. The results indicate that the imported human capital was responsible for 59% to 88% of this total growth between 1820 and 1900.

    Full Text Available In discussing the theme Imperialism, Crisis and education, the essay points out aspects of our historical totality in relation to recent crises through which it passed capitalism, and its relationship to changes in Brazilian educational policies. Education remains at the heart of development projects, as a producer of knowledge, as well as guiding the processes of social conformation. They also discussed the aftermath of the crisis: the rise of social inequality and the increase of labor exploitation. Make clear our project of society and education, as resistance movements to the survival of capitalism is a necessity in building movements of counter-hegemony.

    Full Text Available The increasing problems with multidrug resistance in relation to Corynebacterium, including C. diphtheriae, are examples of challenges confronting many countries. For this reason, Brazilian C. diphtheriae strains were evaluated by the E-Test for their susceptibility to nine antibacterial drugs used in therapy. Resistance (MIC < 0.002; 0.38 µg/ml to penicillin G was found in 14.8% of the strains tested. Although erythromycin (MIC90 0.75 µg/ml and azithromycin (MIC90 0.064 µg/ml were active against C. diphtheriae in this study, 4.2% of the strains showed decreased susceptibility (MIC 1.0 µg/ml to erythromycin. Multiple resistance profiles were determined by the disk diffusion method using 31 antibiotics. Most C. diphtheriae strains (95.74% showed resistance to mupirocin, aztreonam, ceftazidime, and/or oxacillin, ampicillin, penicillin, tetracycline, clindamycin, lincomycin, and erythromycin. This study presents the antimicrobial susceptibility profiles of Brazilian C. diphtheriae isolates. The data are of value to practitioners, and suggest that some concern exists regarding the use of penicillin.

    Full Text Available The definition of giftedness is related to the existence of high abilities in several and different fields and involves the study of process as intelligence, motivation, creativity and leadership. Due to the lack of research in this area, the present study aimed to review researches about giftedness on Brazilian periodic publications, in two databases: Scielo and Pepsic. The results pointed to the existence of 19 theorical and empiric articles, published between 2002 and 2009, that approached distinct dimensions of giftedness: conceptual definitions, models and forms of identification, models of attendance, Brazilian laws to guide the performance, researches with teachers, family and school environment, studies of cognitive, social and emotional dimension, finally behaviors and emotional disorders related to the giftedness. The articles analysis allowed concluding the recent interest for the theme, it was observed divergences in the definition of the concept, the lack of specific tests, with validity and standards, beyond the recognition of the importance of the school environment and the psychologis

    1998-06-01

    Beans are a major source of dietary protein in Brazil. However, high losses due to insect infestation occur after each harvest. To combat these losses, radiation processing of beans offers promise as an alternative to chemical treatment, provided the nutritional quality of beans is not impaired by the radiation treatment. Conflicting results have been published about the effect of radiation on the biological value of legume proteins. Therefore, two varieties of Brazilian beans were studied: 1) Phaseolus vulgaris L., var. carioca and 2) Vigna unguiculata (L.) Walp, var. macacar. The beans were irradiated with doses of 0, 0.5, 1.0, 2.5, 5.0 and 10 kGy. Since irradiated beans will be consumed after appropriate storage, the beans under study were stored for 6 months at ambient temperature. Protein quality was measured by a biological assay employing the nitrogen balance approach in weanling rats. The animals were fed with optimally cooked beans, which were the only source of protein ({approx}10%). Nitrogen contents of legumes, diets, animal urine and faeces were determined by Kjeldahl analysis. The indices for apparent protein quality: net protein utilisation, digestibility and biological value were not influenced by irradiation. Thus, radiation treatment of Brazilian beans offers considerable promise as an effective insect disinfestation process, without impairing the biological quality of the valuable bean protein.

    To assess the current practices in gout management among Brazilian rheumatology residents. We performed a cross-sectional online survey among all the rheumatology residents and those rheumatologists who had just completed their training (post-residency (PR)) regarding their approach to gout management. Results were compared with the 2012 American College of Rheumatology (ACR) gout guidelines and with the responses of a previous survey with a representative sample of practicing Brazilian rheumatologists (RHE). We received 224 responses (83%) from 271 subjects. Among all respondents, the first-choice treatment for gout flares was the combination of a nonsteroidal anti-inflammatory drug + colchicine for otherwise healthy patients. A target serum urate 75%. Less than 70% reported starting allopurinol at low doses (≤100 mg/day) for patients with normal renal function and <50% reported maintaining urate-lowering therapy indefinitely for patients without tophi. Among residents and PR, the residency stage was the main predictor of concordance with the ACR guidelines, with PR achieving the greatest rates. Reported practices were commonly concordant with the 2012 ACR gout guidelines, especially among PR. However, some important aspects of gout management need improvement. These results will guide the development of a physician education program to improve the management of gout patients in Brazil.

  9. The Brazilian education system. Students with disabilities

    Directory of Open Access Journals (Sweden)

    Roberto Dainese

    2010-07-01

    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.

  10. Effects of Brazilian propolis on Leishmania amazonensis

    Full Text Available Leishmaniasis, an endemic parasitosis that leads to chronic cutaneous, mucocutaneous or visceral lesions, is part of those diseases, which still requires improved control tools. Propolis has shown activities against different bacteria, fungi, and parasites. In this study we investigated the effect of four ethanolic extracts of typified propolis collected in different Brazilian states, on Leishmania amazonensis performing assays with promastigote forms, extracellular amastigotes, and on infected peritoneal macrophages. Ethanolic extracts of all propolis samples (BRG, BRPG, BRP-1, and BRV were capable to reduce parasite load as monitored by the percentage of infected macrophages and the number of intracellular parasites. BRV sample called red propolis, collected in the state of Alagoas, and containing high concentration of prenylated and benzophenones compounds, was the most active extract against L. amazonensis. The anti-Leishmania effect of BRV sample was increased in a concentration and time dependent manner. BRV treatment proved to be non-toxic to macrophage cultures. Since BRV extract at the concentration of 25 µg/ml reduced the parasite load of macrophages while presented no direct toxic to promastigotes and extracellular amastigotes, it was suggested that constituents of propolis intensify the mechanism of macrophage activation leading to killing of L. amazonensis. Our results demonstrate, for the first time, that ethanolic extracts of Brazilian propolis reduce L. amazonensis infection in macrophages, and encourage further studies of this natural compound in animal models of leishmaniasis.

  11. The citation pattern of Brazilian economists

    Full Text Available This paper studies the determinants of international citations by Brazilian economists in papers published in the top domestic journals in 1994 and 2004. Brazilian research in economics has become more open to international influence and widespread geographically; researchers more specialized and technically oriented and the research topics more diversified. However, Brazil is plagued by editorial favoritism, reflected in the negative and significant impact of references to the works authored by domestic journals editors on international citations. We also find that longer technical papers written on topics other than the economic history of Brazil are more likely to cite foreign literature.Este artigo estuda os determinantes das citações internacionais dos economistas brasileiros em artigos publicados nas principais revistas domésticas de economia nos anos 1994 e 2004. A pesquisa de economia no Brasil se tornou mais aberta à influencia internacional e mais espalhada geograficamente; os pesquisadores mais especializados e tecnicamente orientados e os tópicos de pesquisa mais diversificados. Entretanto, a pesquisa continua sendo prejudicada pelo favoritismo editorial, refletido no impacto negativo e significante das referências dos autores aos trabalhos dos editores das revistas domésticas sobre as citacoes internacionais. Constatamos que artigos técnicos mais longos sobre tópicos que não sejam sobre história econômica do Brasil têm maior chance de citar a literatura internacional.

  12. Ochratoxin A in Brazilian green coffee

    LEONI Luís A.B.

    2001-01-01

    Full Text Available Ochratoxin A is a nephrotoxic, teratogenic and imunotoxic compound produced by Aspergillus and Penicillium spp. It is a suspected carcinogen to humans and it is carcinogenic to rats. Recently it has drawn attention because it has been found in coffee and it has been the object of regulation by coffee importing countries. Brazil is the largest coffee producing country and its largest consumer. In order to conduct an initial assessment of the situation of the coffee produced in the country and offered to its population, one hundred and thirty two samples of Brazilian green coffee from 5 producing states (Minas Gerais, Paraná, São Paulo, Espírito Santo and Bahia and destined for the home market, were collected at sales points at the cities of Londrina and Santos, Brazil, and analyzed for ochratoxin A. The toxin was isolated in immunoaffinity columns and quantified by HPLC with florescence detection. The limit of detection was 0.7ng/g and the average RSD for duplicates of the samples was 11%. Twenty seven samples were found contaminated with the toxin and the average concentration for the contaminated samples was 7.1ng/g ochratoxin A. Neither the total number of defects nor the number of specific defects according to the Brazilian coffee classification system (black, partly -- black, sour, stinkers-black, stinkers-green, pod beans showed any relation to the contamination of the samples with ochratoxin A.

    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.

  14. Bidding Strategies in Brazilian Treasury Auctions

    2003-06-01

    Full Text Available Most empirical work in treasury auctions use aggregate auction results to examine bidding behavior. We investigate the strategies of bidders in Brazilian treasury auctions using both aggregate and bidder level data and find that more detailed information allows great improvements in the understanding of bidding behavior in treasury auctions. Classifying bidders according to characteristics regarding their institutional category and their nationality, we find evidence of distinct bidding behavior across types of bidders. Moreover, in line with previous evidence in auctions of Japanese government securities, we find that foreign bidders seem to obtain higher profits than those of national institutions. These results suggest that caution should be exercised in the interpretation of testes of bidding behavior that do not take differences in bidder’s characteristics into account and (or that assume that treasury securities are pure common-value goods. We find that Brazilian auctions are relatively illiquid as higher competition yields lower bidders’ discounts. Contrary to theoretical predictions of both common- and private-value auctions, we also find that bidders obtain lower profits in auctions with higher dispersion in bidders’ valuations.

    Full Text Available Brands may be perceived as possessing a set of distinct traits or characteristics, i.e., a personality, similar to aperson. Thus, the personality of a brand is relevant as a source of differentiation in an increasingly competitivemarket environment. In this study, the authors explore the dimensions of brand personality proposed by J. Aaker(1997, seeking to discover the particular evaluation dimensions of the Brazilian context. The study wasconducted in exploratory stages, beginning with a preparatory stage that was carried out by professionals andacademics from the fields of communication and marketing. This was followed by stages of conclusive researchusing an online survey with a sample of 1,302 Brazilian consumers. Two sub-samples were extracted: onecalibration sample for exploratory factor analysis and a validation sample to perform confirmatory factoranalysis in order to verify the convergent and discriminant validities of the final scale. Five dimensions of brandpersonality in Brazil were detected: credibility, joy, audacity, sophistication and sensitivity. These dimensionsshowed some differences in comparison with similar studies that had been carried out in other countries. Thestudy led to a scale of 28 items for measuring brand personality and made it possible to compare competingbrands in terms of brand personality.

    Full Text Available We propose to make a brief review on nasalization phenomena studies in Portuguese, aiming the phonological process of nasal harmonization that occurs in the variety of Brazilian Portuguese spoken in Vitória da Conquista-BA and region, a phenomenon hitherto not described for any Portuguese dialect. To do so, we consider as fundamental, D’Angelis (2002 analysis, which incorporates relevant concepts presented by Trubetzkoy, from the Prague School, and some points of Camara Jr. propose. We also propose to update the discussion with the approaches along the lines of auto segmental phonology, incorporating some insights of Piggott (1992, discussing with other analyzes for nasalization phenomena in other languages, especially Guarani (language of Tupi-Guarani Linguistic Family, as proposed by Costa (2010, which deals with the phonological processes involving nasality and nasal harmony in Brazilian indigenous languages , in order to verify if the researches on nasality phenomena in other languages can shed some light on the processes that occur in Portuguese.

  17. Brazilian obesity prevention and control initiatives.

    Jaime, P C; da Silva, A C F; Gentil, P C; Claro, R M; Monteiro, C A

    2013-11-01

    Obesity prevalence in the Brazilian adult population is 12.5% among men and 16.9% among women. Obesity control has been a subject of concern in Brazilian health policies since the publication of the National Food and Nutrition Policy in 1999. The initiatives include a comprehensive national intersectorial plan for obesity prevention and control focused on confronting its social and environmental causes, development of a food and nutrition education framework aimed at intersectorial public policies in the food and nutritional security field, promotion and provision of healthy food in school environments (linked to family farming), structuring nutrition actions in primary healthcare in the national healthcare system, promoting community physical activity, food regulation and control, and encouragement of public participation and food control. We conclude that several initiatives have been developed in Brazil to deal with the challenge of implementing an intergovernmental, intersectorial response to reverse the rising overweight and obesity rates. The success of this response will depend on a governance model that promotes joint and integrated action by different sectors and active participation of society to consolidate the actions, places and laws that protect health and promote healthy lifestyles.

    2003-04-01

    In this work, a comprehensive phylogenetic study based on 600 base pair nucleotide and on putative 200 amino acid sequences of NS5 was carried out in order to establish genetic relationships among 15 strains of 10 Brazilian flaviviruses: Bussuquara, Cacipacore, dengue type 1, 2 and 4, Iguape, Ilheus, Rocio, Saint Louis encephalitis (SLE), and yellow fever. Phylogenetic trees were created by neighbor-joining and maximum parsimony methods. These trees showed Brazilian flaviviruses grouped into three main branches: yellow fever branch, dengue branch subdivided in types 1, 2 and 4 branches, and Japanese encephalitis virus (JEV) complex branch including SLE virus strains, Cacipacore, Iguape, Rocio, Ilheus and Bussuquara. Viruses transmitted by Aedes mosquitoes, such as dengue and urban yellow fever, that are also the only Flavivirus causing hemorrhagic fevers in Brazil, were grouped in the same cluster. Encephalitis associated viruses, transmitted by Culex mosquitoes such as JEV complex branch including SLE virus strains, Cacipacore, Iguape, Rocio, Ilheus and Bussuquara were also grouped in the same clade.

  19. Diasporic and Transnational Internationalization: The Case of Brazilian Martial Arts

    2015-10-01

    Full Text Available Brazilian diasporas overseas hasreceived little academic interest. Nevertheless, estimates suggest that around three million Brazilians currently live in other countries. The present study looks at a specific type of diaspora: small entrepreneurs from the Brazilian martial arts sector. The study adopts the case study method of research. The unit of analysis is comprised by the martial arts (capoeira and Brazilian jiu-jitsu. Data analysis used secondary and primary data from interviews. Cross-case analysis searched for similarities and differences in the internationalization processes of the two martial arts, using several analytical devices, such as chronologies, timelines, matrices, and pattern matching analysis. Evidences suggest that the concept of diasporic internationalization fits better capoeira than Brazilian jiu-jitsu. However, Brazilian jiu-jitsu shows an initial combination of diasporic and transnational characteristics, but more recently became fully transnational. Brazilian jiu-jitsu became a truly global business, formally organized and professionally managed. Capoeira, however, is still seen as non-commercial and as the preservation and practice of an ancient art. Such ethos, combined with the origin of its members in lower economic classes and their restricted access to capital turns internationalization into an often less profitable activity.

  20. 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 http://dx.doi.org/10.5007/2175-7968.2013v1n31p119Jorge 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

    Full Text Available While in Europe vodka is mainly derived from potatoes or cereals, a large proportion of Brazilian vodka is likely obtained from sugarcane, which contains ethyl carbamate (EC precursors. EC, in addition to several other contaminants and congeners, were investigated in 32 samples of Brazilian vodka. All samples complied with the Brazilian regulations for congeners and contaminants, having EC content below 0.01 mg/L (detection limit. These results are probably related to the processing of vodka, in particular the use of extractive and rectifying stainless steel distillation columns, which allow the production of high strength spirits with low levels of congeners and contaminants.

  4. The role of interest rates in the Brazilian business cycles

    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.

    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.

  6. CORPORATE SOCIAL RESPONSIBILITY PRACTICES AT BRAZILIAN FIRMS

    2014-01-01

    Full Text Available Corporate Social Responsibility practices have been on the rise in recent years in firms all over the world. Brazil, as one of the most important countries emerging on the international scene, is no exception to this, with more and more firms taking up these practices. The present study focuses on analyzing the corporate social responsibility practices that Brazilian companies engage into. The sample used is comprised of 500 firms grouped by geographical area; the theoretical framework is based on stakeholder and institutional theories; and the technique used for the analysis is the biplot, more specifically the HJ Biplot and cluster analysis. From the results obtained it is possible to infer that the CSR variables corresponding to environmental practices are more closely linked to companies located in the northern areas of Brazil. Social and community practices are related to companies primarily in the southern and northeastern regions of the country.

    2013-12-01

    The objective of this study was to identify the motives for sport participation in a sample of young Brazilian athletes according to sex, age, and training history. A total of 1,517 participants (714 girls, 803 boys) ages 12 to 18 years were included in the study. The Portuguese version of the Participation Motivation Questionnaire was used to identify motives for sport participation. The most important motives were Skill Development and Fitness, whereas the least important were Fun and Achievement/Status. Sex, age, type of sport, onset of training, duration of training, training volume, and competitive experience significantly influenced the motives for sport participation reported by the athletes. These results will contribute to establish intervention programs designed to reduce sport dropout rates among young athletes.

    Through refereed papers, this volume focuses on the foundations of the Bayesian paradigm; their comparison to objectivistic or frequentist Statistics counterparts; and the appropriate application of Bayesian foundations. This research in Bayesian Statistics is applicable to data analysis in biostatistics, clinical trials, law, engineering, and the social sciences. EBEB, the Brazilian Meeting on Bayesian Statistics, is held every two years by the ISBrA, the International Society for Bayesian Analysis, one of the most active chapters of the ISBA. The 12th meeting took place March 10-14, 2014 in Atibaia. Interest in foundations of inductive Statistics has grown recently in accordance with the increasing availability of Bayesian methodological alternatives. Scientists need to deal with the ever more difficult choice of the optimal method to apply to their problem. This volume shows how Bayes can be the answer. The examination and discussion on the foundations work towards the goal of proper application of Bayesia...

    2016-01-01

    Full Text Available Abstract: Currently the importance of using alternative strategies for biodiversity conservation is emphasized and since the establishment of germplasm bank is an alternative to the conservation of endangered species. This is a technique of great importance for the maintenance of Brazilian fauna. Since the early70'sthere was a growing concern about the need to preserve essential genetic resources for food and agriculture, mainly for conservation of genetic material from farm animals. Thus was created the Brasilia Zoo, in July 2010, the first Germplasm Bank of Wild Animals in Latin America, as an alternative strategy for the conservation of threatened or endangered species, using both gametes and somatic cells and stem cells. Then we argue to create new banks or research networks among different regions with aimed to tissue preservation.

  10. The multiplicity of Brazilian Social Psychology

    2014-02-01

    Full Text Available Brazilian Social Psychology has many definitions, theories and objects of study. In this essay, based on Actor-Network Theory, we argue that these are not different aspects or attributes of a single object, but elements that help to perform different versions of this object. They are, therefore, elements that make Social Psychologies different, although related to each other. They produce a multiple Social Psychology, which is more than one and, at the same time, less than many. In doing so, we strived to call attention to the possibility of ordinating and coordinating reality in different ways, of recognizing that there are multiple and diverse actants in a discipline and of making a Social Psychology that searches for complex connections that articulate humans and non-humans and perform multiple realities.

  11. Brazilian spotted fever: a reemergent zoonosis

    2008-01-01

    Full Text Available Brazilian spotted fever is caused by the bacterium Rickettsia rickettsii, which is the most pathogenic species of the spotted-fever rickettsiae group and is transmitted by the bite of infected ticks. Amblyomma cajennense is the most important tick species involved in the cycle of this zoonosis in Brazil as it presents low host specificity, great number of natural reservoirs and wide geographic distribution. It was first described in the state of São Paulo in 1929 and later in Rio de Janeiro, Minas Gerais and Bahia. The number of cases decreased in the 1940's with the development of new plague control techniques and antibiotics. In the last decades, the number of new cases has increased. The current review aimed at reporting some of the epidemiological and public health aspects of this reemergent disease with new foci, mainly in the southeastern region of Brazil.

    2015-07-01

    The XXXVII Brazilian Meeting on Nuclear Physics (or XXXVII RTFNB 2014) gave continuity to a long sequence of workshops held in Brazil, devoted to the study of the different aspects of nuclear physics. The meeting took place in the Maresias Beach Hotel, in the town of Maresias (state of São Paulo) from 8th to 12th September 2014. Offering gentle weather, a charming piece of green land of splendid natural beauty with beach and all amenities, the place had all the conditions for very pleasant and fruitful discussions. The meeting involved 162 participants and attracted undergraduate and graduate students, Brazilian and South American physicists and invited speakers from overseas (USA, Italy, Spain, France, England, Switzerland, Germany and South Corea). In the program we had plenary morning sessions with review talks on recent developments in theory, computational techniques, experimentation and applications of the many aspects of nuclear physics. In the parallel sessions we had a total of 58 seminars. This volume contains 60 written contributions based on these talks and on the poster sessions. Evening talks and poster sessions gave still more insight and enlarged the scope of the scientific program. The contributed papers, representing mainly the scientific activity of young physicists, were exhibited as posters and are included in the present volume. Additional information about the meeting can be found at our website: http://www.sbfisica.org.br/~rtfnb/xxxvii-en Support and sponsorship came from brazilian national agencies: Conselho Nacional de Desenvolvimento Científico e Tecnoógico (CNPq); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Fundação de Amparo á Pesquisa do Estado de São Paulo (FAPESP); Fundação de Amparo á Pesquisa do Estado do Rio de Janeiro (FAPERJ); Sociedade Brasileira de Física (SBF) and Instituto de Física da Universidade de São Paulo (IFUSP).

    The identification of cytogenetic abnormalities in schizophrenic patients may provide clues to the genes involved in this disease. For this reason, a chromosomal analysis of samples from 62 schizophrenics and 70 controls was performed with trypsin-Giemsa banding and fluorescence in situ hybridization of the X chromosome. A clonal pericentric inversion on chromosome 9 was detected in one male patient, and we also discovered mosaicism associated with X chromosome aneuploidy in female patients, primarily detected in schizophrenic and normal female controls over 40 years old. When compared with age-matched female controls, the frequency of X chromosome loss was not significantly different between schizophrenics and controls, except for the 40- to 49-year-old age group. Our findings suggest that the X chromosome loss seen in schizophrenic patients is inherent to the normal cellular aging process. However, our data also suggest that X chromosome gain may be correlated with schizophrenia in this Brazilian population.

    Sixteen extracts, obtained from eight Brazilian plants of Annonaceae family, were screened for their antibacterial activity: Xylopia frutescens, X. aromatica, X. amazonica, X. benthamii, Annona ambotay, A. crassiflora, A. muricata and A. cherimolia. Amongst the investigated extracts, six showed antibacterial activity against at least one of the tested organisms at the concentration of 100 microg/mL. The most active extracts were those prepared from X. frutescens, X. amazonica, and A. ambotay. A phytochemical screening showed the presence of anonaceus acetogenins in some active extracts. Eleven diterpenoids were also tested for comparison purposes. Six were natural products, previously isolated from Xylopia sp. (kaurenoic, frutoic, xylopic, 15beta-hydroxy-kaurenoic and trachylobanic acids plus kaurenol) and five were derivatives of such compounds, obtained by esterification or reduction reactions. Trachylobanic acid showed antibacterial activity against B. subtilis and S. aureus.

    Results and discussion: Age at diagnosis was between 10 and 32 months and the severity of the disease correlated with the increasing of age at diagnosis. The predominant symptoms were vomiting, weight loss, and hepatomegaly. Severe renal tubular acidosis manifested in one child. All patients had remission of symptoms after dietary modification. The sequencing of the ALDOB gene identified one homozygous patient for the mutation c.524C>A (p.A175D, while the others were compound heterozygous for c.360_363delCAAA (p.N120KfsX32, c.178C>T (p.R60X mutations, c.448G>C (p.A150P and c.524C>A (p.A175D. Clinical improvement of patients after dietary treatment is suggestive of the diagnosis, confirmed by molecular analysis. The prevalence of mutations found in our Brazilian patients is different from those of international literature.

    2012-01-01

    This work deals with a computational investigation on the small ballistic reentry Brazilian vehicle SARA (acronyms for SAt\\'elite de Reentrada Atmosf\\'erica). Hypersonic flows over the vehicle SARA at zero-degree angle of attack in a chemical equilibrium and thermal non-equilibrium are modeled by the Direct Simulation Monte Carlo (DSMC) method, which has become the main technique for studying complex multidimensional rarefied flows, and that properly accounts for the non-equilibrium aspects of the flows. The emphasis of this paper is to examine the behavior of the primary properties during the high altitude portion of SARA reentry. In this way, velocity, density, pressure and temperature field are investigated for altitudes of 100, 95, 90, 85 and 80 km. In addition, comparisons based on geometry are made between axisymmetric and planar two-dimensional configurations. Some significant differences between these configurations were noted on the flowfield structure in the reentry trajectory. The analysis showed t...

  18. Aging, Gender and Sexuality in Brazilian Society

    Guita Grin Debert

    2014-04-01

    Full Text Available Drawing on the interplay between gender, aging, and sexuality, the aim of this article is twofold: (1 to show how Brazilian gerontologists treat gender differences and sexual activity in old age; (2 to analyze the  ways  discourses regarding the aging body and sexuality are perceived and evaluated by older women and men . I argue that  attempts of gerontologists’ to eroticize old age have to contend with the widespread notion that the desire for sex is inevitably lost with age. Thus, in the retiree associations that were studied, men had a tendency to assume they are not ‘old’ because their erectile function was still in good condition, and divorced or widowed women, in senior citizen associations, tend to regard themselves as happy due to having freed themselves from the sexual obligations imposed by marriage. In both cases, the dominant belief that there is a loss of sexual desire in old age was reproduced.

    2016-01-01

    Power Grids and other delivery networks has been attracted some attention by the network literature last decades. Despite the Power Grids dynamics has been controlled by computer systems and human operators, the static features of this type of network can be studied and analyzed. The topology of the Brazilian Power Grid (BPG) was studied in this work. We obtained the spatial structure of the BPG from the ONS (electric systems national operator), consisting of high-voltage transmission lines, generating stations and substations. The local low-voltage substations and local power delivery as well the dynamic features of the network were neglected. We analyze the complex network of the BPG and identify the main topological information, such as the mean degree, the degree distribution, the network size and the clustering coefficient to caracterize the complex network. We also detected the critical locations on the network and, therefore, the more susceptible points to lead to a cascading failure and even to a blac...

    First Brasflux Workshop; Santa Maria, Rio Grande do Sul, Brazil, 14-15 November 2011 Last November, 33 researchers participated in a workshop to establish Brasflux, the Brazilian network of carbon flux stations, with the objective of integrating previous efforts and planning for the future. Among the participants were those leading ongoing flux observation projects and others planning to establish flux stations in the near future. International scientists also participated to share the experiences gained with other networks. The need to properly characterize terrestrial ecosystems for their roles in the global carbon, water, and energy budgets has motivated the implementation of hundreds of micrometeorological research sites throughout the world in recent years. The eddy covariance (EC) technique for turbulent flux determination is the preferred method to provide integral information on ecosystematmosphere exchanges. Integrating the observations regionally and globally has proven to be an effective approach to maximizing the usefulness of this technique for carbon cycle studies at multiple scales.

    The digital, decimetric (950-2500 MHz) Brazilian Solar Spectroscope (BSS, Sawant, H.S., Subramanian, K.R., Faria, C., et al. Brazilian Solar Spectroscope (BSS). Solar Phys. 200, 167-176, 2001) with high time (10-1000 ms) and frequency (1-10 MHz) resolution is in regular operation since April, 1998, at the National Space Research Institute (INPE) at São José dos Campos, Brazil. The BSS has now been upgraded with a new digital data acquisition and data processing system. The new version of the BSS has improved the observational possibilities with the capability to record up to 200 frequency channels available in the selectable frequency range 950-2500 MHz. The GPS receiver permits the acquisition of data with time accuracy in the order of 0.1 ms. The software system of the BSS is composed by two distinct modules: the first, data acquisition system provides a flexible Graphical User Interface (GUI) that allows one to choose the observational parameters. The second module is the real time visualization system that permits real time visualization of the observed dynamic spectrum and additionally allows procedures for visualization and preliminary analysis of the recorded solar spectra. Using the new visualization system, we have realized two new types of dm-radio fine structures: narrow band type III bursts with positive as well as negative group frequency drift and dots emissions arranged in zebra-like and fiber-like chains. Furthermore, we have found flare generated fast wave trains according to their tadpole signature in wavelet power spectra for a decimetric type IV radio event (June 6, 2000 flare).

    Full Text Available Investigates the theme known as “Knowledge Management” (KM in three large Brazilian organizations trying to discuss its concepts, constituent elements, managerial approaches and tools, while aiming at leaving behind the purely terminological discussion, which is innocuous and naive. The basic presuppositions were two: (i most of what it´s referred to or named KM is actually “Information Management” (IM and IM is just one of the components of KM. KM is more than simply IM due to the fact that it includes and incorporates other concerns, such as the creation, use and sharing of information and knowledge in the organizational context; (ii a conceptual model or map can be formulated based on three basic conceptions: (a a strategic conception of information and knowledge, (b the introduction of such strategy in the tactical and operational levels through the several managerial approaches and informaion technology tools and (c the creation of an organizational space for knowledge. The main objective is to investigate and analyze the conceptions, motivations, practices and results of KM effectively implemented in three large Brazilian organizations. The qualitative research strategy used was the study of multiple cases with incorporated units of analysis and three criteria ere observed for the judgment of the quality of the research project: validity of the construct, external validity and reliability. Multiple sources of evidence were used and data analysis consisted of three flows of activities: data reduction, data displays and conclusion drawing/verification. The results confirmed the presuppositions and the fact that KM means a rethinking of management practices in the information ea. It was also identified that the main challenges facing organizations committed to KM have its focus on change management, cultural and behavioral issues and the creation of an enabling context that favors the creation, use and sharing of information and

    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.

    This paper presents the major characteristics of the Brazilian tax system, after underlining the modifications it went through since 1988, when the country adopted a new and democratic Constitution. One important feature is the marked incidence of indirect consumer and production taxes (49% of all tax revenues) in place of direct taxes on income, inheritance, and capital gains. This imbalance between indirect and direct taxes explains, in large part, the elevated regressivity of the Brazilian...

    Full Text Available PURPOSE: 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]. METHODS: 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. RESULTS: The citation counts were statistically significantly higher (P<0.001 in the Foreign Group (10.50 compared with the Brazilian Group (0.45. The likelihood citation was statistically significantly higher (P<0.001 in the Foreign Group (20/20 - 100% compared with the Brazilian Group (8/20 - 40%. The subgroup analysis of the language influence in Brazilian articles showed that the citation counts were statistically significantly higher in the papers published in English (P<0.04. Of 37 possible CONSORT items, the mean for the Foreign Group was 20.55 and for the Brazilian Group was 13.65 (P<0.003. CONCLUSION: The number of citations and the quality of reporting of clinical trials in Brazilian journals of ophthalmology still are low when compared with the foreign journals of ophthalmology with highest Impact Factor®.

    Full Text Available National surveys are relevant for the study of sleep epidemiology since they can provide specific data about sleep in large dimension with important implications for the health system. Thus, the aim of this study was to investigate the prevalence of sleep complaints among the Brazilian population using a randomized cluster sample according to region and socioeconomic class. For this, a 3-stage sampling technique was used to randomly select Brazilian subjects of both genders older than 16 years. A total of 2017 subjects, from 132 different cities, were selected to estimate prevalence in the Brazilian population with a sampling error of ±2%. Questions about sleep complaints were administered face-to-face by Instituto Datafolha interviewers on April 10 and 16, 2012. Data were expanded using a weighted variable. The results showed that 76% of the study population suffers from at least 1 sleep complaint, indicating that approximately 108 million Brazilians may be affected by sleep disorders. On average, each subject had 1.9 sleep problems with the most common complaints being light and insufficient sleep, snoring, moving a lot during sleep, and insomnia, which usually occurred more than 3 times per week. Low income was associated with higher number of sleep complaints only in Northeast and Southeast regions. In conclusion, this study showed a high prevalence of sleep complaints in a sample of the Brazilian population, suggesting that sleep disorders may be markedly frequent in the Brazilian population with a possible correlation with the socioeconomic situation of the interviewed subjects.

    Significant progress has been obtained since the First Brazilian Consensus Conference on H. pylori Infection held in 1995, in Belo Horizonte, MG, and justify a second meeting to establish updated guidelines on the current management of H. pylori infection. The Second Brazilian Consensus Conference on H. pylori Infection was organized by the Brazilian Federation of Gastroenterology and Brazilian Nucleus for the Study of Helicobacter and took place on June, 19-20, 2004 in São Paulo, SP. Thirty six delegates coming from 15 different Brazilian states including gastroenterologists, pathologists, microbiologists and pediatricians undertook the meeting. The participants were allocated in one the five main topics of the meeting: H. pylori and dyspepsia, H. pylori and NSAIDs, H. pylori and gastroesophageal reflux disease, H. pylori treatment, and H. pylori retreatment. Seventy per cent and more votes were considered as acceptance for the final statement. The results were presented during a special session on the VI Brazilian Week of Digestive System, in Recife, PE (October 2004), and this publication represents the summary of the main recommendations and conclusions emerged from the meeting.

    Full text of publication follows: Gamma radiation from radionuclides which are characterized by half lives comparable to the age of the earth, such as 40 K and the radionuclides from the 238 U and 232 Th series, and their decay products, represent the main terrestrial source of irradiation to the human body. Their concentrations vary for different types of rocks, where high radiation levels are associated with igneous rocks such as granite. Thorium, uranium and potassium concentrations of granitic rocks are intimately related to their mineral compositions and general petrologic features. Then, these features associated with effects of weathering and metamorphism produce expressive alterations in the relationship between the natural radionuclides (Th, U, K, Th/U and Th/K). Consequently, the measurements of thorium, uranium, and potassium concentrations of different granite samples result on individual differentiation sequences. From the 232 Th, 238 U and 40 K activity concentrations obtained for each sample, it is possible to evaluate their respective dose rates in air, when these stones are used as tiling rocks. These results are of great interest in the environmental radiological protection study, since granites are widely used as building and ornamental materials, including as indoor covering. In this way, the Laboratory of Radioecology (L.A.R.A.) of the Physics Institute of the Universidade Federal Fluminense (I.F. -U.F.F.) has been performing analyzes on more than one hundred differ ent types of the main Brazilian commercial granites in last two years [1]. Using NaI and HP Ge gamma-ray spectrometers to determine the concentration of natural radionuclides in these samples, the annual effective dose rates and the gamma activity concentration index have been evaluated and compared to the limits proposed by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) and European Commission (E.C.). In addition, the correlations between thorium

    OBJECTIVE To determine the distribution of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides in Brazilian adolescents, as well as the prevalence of altered levels of such parameters. METHODS Data from the Study of Cardiovascular Risks in Adolescents (ERICA) were used. This is a country-wide, school-based cross-sectional study that evaluated 12 to 17-year old adolescents living in cities with over 100,000 inhabitants. The average and distribution of plasma levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides were evaluated. Dyslipidemia was determined by levels of total cholesterol ≥ 170 mg/dl, LDL cholesterol ≥ 130 mg/dl, HDL cholesterol < 45 mg/dL, or triglycerides ≥ 130 mg/dl. The data were analyzed by gender, age, and regions in Brazil. RESULTS We evaluated 38,069 adolescents - 59.9% of females, and 54.2% between 15 and 17 years. The average values found were: total cholesterol = 148.1 mg/dl (95%CI 147.1-149.1), HDL cholesterol = 47.3 mg/dl (95%CI 46.7-47.9), LDL cholesterol = 85.3 mg/dl (95%CI 84.5-86.1), and triglycerides = 77.8 mg/dl (95%CI 76.5-79.2). The female adolescents had higher average levels of total cholesterol, LDL cholesterol, and HDL cholesterol, without differences in the levels of triglycerides. We did not observe any significant differences between the average values among 12 to 14 and 15- to 17-year old adolescents. The most prevalent lipid alterations were low HDL cholesterol (46.8% [95%CI 44.8-48.9]), hypercholesterolemia (20.1% [95%CI 19.0-21.3]), and hypertriglyceridemia (7.8% [95%CI 7.1-8.6]). High LDL cholesterol was found in 3.5% (95%CI 3.2-4.0) of the adolescents. Prevalence of low HDL cholesterol was higher in Brazil's North and Northeast regions. CONCLUSIONS A significant proportion of Brazilian adolescents has alterations in their plasma lipids. The high prevalence of low HDL cholesterol and hypertriglyceridemia, especially in Brazil's North and Northeast regions, must be

    ABSTRACT OBJECTIVE To describe the prevalence of asthma and physician-diagnosed asthma in Brazilian adolescents. METHODS Cross-sectional, national, school-based study with adolescents from 12 to 17 years old, participants in the Study of Cardiovascular Risks in Adolescents (ERICA). The study stratified the sample by region and grouped according to schools and classes with representativeness to the set of cities with more than 100,000 inhabitants of the Country, macro-regions, capitals, and Federal District. A questionnaire collected data through a self-filled in method. We calculated the prevalences and their confidence intervals of 95% (95%CI) according to sex, age group, type of school and skin color. RESULTS Between 2013 and 2014, 74,589 adolescents were evaluated, 55.3% of the female sex. The total prevalence of active asthma was of 13.1% (95%CI 12.1-13.9), being higher in girls (14.8%; 95%CI 13.7-16.0) when compared to boys (11.2%; 95%CI 10.3-12.2) in all geographical strata examined. It was also higher between students of private schools (15.9%; 95%CI 14.2-17.7) when compared to public ones (12.4%; 95%CI 11.4-13.4). It was higher in the Southeast region (14.5%; 95%CI 12.9-16.1), and in the city of Sao Paulo (16.7%; 95%CI 14.7-18.7). The lowest prevalence was observed in North region (9.7%; 95%CI 9.7-10.5), and in Teresina (6.3%; 95%CI 4.9-7.7). The prevalence of physician-diagnosed asthma was of 8.7% (95%CI 8.2-9.1); higher in the North region (13.5%; 95%CI 12.7-14.2), and in Porto Alegre (19.8%; 95%CI 17.5-22.3). It was lower in the Midwest (6.9%; 95%CI 6.0-7.8), and in Cuiaba (4.8%; 95%CI 3.8-5.9). We found no significant difference in the expression of this rate between the sexes, as well as in other variables evaluated by the study. CONCLUSIONS The prevalence of asthma in Brazilian adolescents is high. Rates of active asthma and physician-diagnosed asthma vary widely in different regions and capitals evaluated by the ERICA. These results may assist in the

    Full Text Available The present article presents different phases that the Brazilian Defense Ministry has passed through, since its inception during Fernando Henrique Cardoso's second presidential term (1999-2002 until the current administration of Luís Inácio Lula da Silva (2003-2006, under its respective ministers of Defense. It has been seen as one of the important stages in the re-constitutionalization of the country, insofar as it establishes the submission of Armed Forces commanders to a civilian minister, and although some analysts have considered that such submission is actually achieved, we point here to the military resistance and insubordination to civil power that are the result of an authoritarian legacy. To the extent that the Ministry of Defense is unable to implement its own policies in which the military would be required to follow civilian guidance, this article concludes with considerations on the civil Defense Ministry's political and institutional fragility vis-a-vis military command. The latter has been able to retain high levels of decision making autonomy in its relationship to the Ministry and its structure.

    Full Text Available Most of the recent astonishing export growth in Brazil came from firms which already exported. The export base was not able to grow at the same pace. Since expanding the export base may have several positive effects on firms' productivity and size, in this paper we provide a four-level classification of Brazilian industrial firms according to their potential to export, and we identify a subset of non-exporting firms which are potential exporters. The effects of export stimulating policies may be improved by focusing more closely on these firms.O recente crescimento das exportações no Brasil se baseou fortemente naquelas firmas já exportadoras, e a base exportadora não conseguiu acompanhar o mesmo ritmo de crescimento. Considerando que expandir a base exportadora pode ter efeitos positivos sobre a produtividade e tamanho das firmas, neste artigo classificamos as firmas industriais brasileiras em quatro níveis de acordo com o potencial exportador, e especialmente identificamos um subconjunto de firmas que não exportam mas que são potenciais exportadoras. Os efeitos das políticas de promoção às exportações podem ser maximizados se elas forem focalizadas nestas firmas.

    Including students' perceptions in the educational process is considered a key component in monitoring the quality of academic programs. This study aimed to evaluate the concept of one's learning experience in endodontic teaching from the perspective of a group of Brazilian students. A total of 126 self-administered, structured questionnaires were distributed to undergraduate dental students enrolled in endodontics courses during the second semester of the 2009 academic year. The questionnaires were administered during final examinations and focused on students' opinions concerning learning during endodontic treatments, time spent during endodontic treatments, difficulties found during endodontic treatments, quality of endodontic treatments performed, characteristics of the technique employed, and suggestions to improve endodontic teaching. Ninety-one percent of the questionnaires were returned for evaluation. The obtained answers were discussed and analyzed, thereby generating quantitative and qualitative data showing students' perceptions of their experiences in endodontics courses. The main points that can affect the teaching of endodontics, according to the undergraduate students, included patients' absences and delays, selection of patients, preclinical and clinical training, difficulties found, type of technique employed, and teachers' orientation during endodontic treatment. The students' perceptions provided valuable information about the development of the course and the teacher-student relationship, together with the added intention of enhancing the teaching of endodontics as well as other courses.

    2012-10-01

    Full Text Available This paper analyzes the phenomenon known as accrual anomaly in Brazil. In particular, we examine two hypotheses: (a that the earnings expectation included in the stock price fails to reflect the difference in persistence of the earnings components (accruals and cash flows; and (b that the construction of a hedge portfolio by taking a long (short position in assets with low (high accruals generates consistently abnormal returns. The data set includes nonfinancial firms listed on the BM&FBOVESPA between 1990 and 2008. The empirical tests required conducting panel data regressions to identify the persistence of earnings and theircomponents; the Mishkin test to identify whether the market rationally prices earnings; and the composition of a zero-investment (hedge portfolio to analyze whether a trading strategy based on accruals consistently provides abnormal positive returns. The results indicate that the accrual component is not mispriced by the Brazilian market, and that a trading strategy based on accruals does not provide consistently positive returns. Although this evidence does not encourage arbitrage, the results are relevant from various perspectives. The methodology applied permitted identifying the quality of earnings and of their components, as well as association between the components of earnings and returns.

    Full Text Available Although phenolic compounds produced by lichens have been widely investigated in antitumor assays, only a small number have been evaluated for mutagenicity and genotoxicity. This study evaluated protocetraric, hypostictic, psoromic, and salazinic acids for their potential genotoxic or antigenotoxic activity against somatic cells of Drosophila melanogaster. These compounds were isolated from the lichens Parmotrema dilatatum, Pseudoparmelia sphaerosphora, Usnea jamaicensis, and Parmotrema cetratum, respectively, collected from the Brazilian Cerrado biome. The compounds were evaluated at 0.75, 1.5, 3.0, and 6.0 mmol L–1 using the SMART test, employing standard and high-bioactivation crosses of Drosophila melanogaster. Doxorubicin (DXR was the positive control. Psoromic and salazinic acids proved toxic at 6.0 mM. None of the compounds evaluated exhibited mutagenicity, but each of them significantly reduced genetic damage caused by DXR, proving antigenotoxic when tested on somatic cells of D. melanogaster. DOI: http://dx.doi.org/10.17807/orbital.v9i1.897

    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.

    Full Text Available The antileishmanial and immunomodulatory effects of propolis collected in Botucatu, São Paulo State, Brazil, were evaluated in Leishmania (Viannia braziliensis experimental infection. The antileishmanial effect of propolis on promastigote forms was verified by reducing growth and by promoting morphologic alterations observed by scanning electron microscopy. In in vitro immunomodulatory assays, macrophages were pretreated with propolis and then infected with L. (V. braziliensis. In vivo, supernatants from liver cells and peritoneal exudate of BALB/c mice pretreated with propolis and infected with Leishmania (107/mL promastigotes were collected, and TNF-α and IL-12 were measured by ELISA. Macrophages incubated with propolis showed a significant increase in interiorization and further killing of parasites. An increased TNF-α production was seen in mice pretreated with propolis, whereas IL-12 was downregulated during the infection. In conclusion, Brazilian propolis showed a direct action on the parasite and displayed immunomodulatory effects on murine macrophages, even though the parasite has been reported to affect the activation pathways of the cell. The observed effects could be associated with the presence of phenolic compounds (flavonoids, aromatic acids, and benzopyranes, di- and triterpenes, and essential oils found in our propolis sample.

    Full Text Available This article aims to reflect on the territorial dimension has been addressed in the current Brazilian health policy. Provides an initial approximation of the theoretical discussion about the category territory and its implications for social policy. Then we analyze how this category was included in the principles and guidelines of the National Health System, deployed in key programs and normative instruments of health policy from 1990. It is concluded that: the territorial dimension was present from conception through SUS guideline regionalization of activities and services. In the main programs implemented in the 1990s, the territorial dimension had a character cutouts geographical and normative instruments gave centrality to the process of decentralization. However, from the 2000s, the regionalization strategy, pointing to the territorial perspective, gains greater significance. However, we still need to overcome the logic purely political-administrative and act so as to identify the real needs of the people, their potential, diversity and particularities, towards "used territory" referred to Milton Santos.

    The rôle of astronomy in the Brazilian cultural diversity -though little known world- has been enormous. Thus, the different forms of popular music and erudite, find musical compositions and lyrics inspired by the stars, the eclipses in rare phenomena such as the transit of Venus in front of the sun in 1882, the appearance of Halley's Comet in 1910, in the Big Bang theory. Even in the carnival parades of the blocks at the beginning of the century astronomy was present. More recently, the parade of 1997, the samba school Unidos do Viradouro, under the direction of Joãozinho Trinta, offered a new picture of the first moments of the creation of the universe to join in the white and dark in the components of their school, the idea of matter and anti-matter that reigned in the early moments of the creation of the universe in an explosion of joy. Examples in classical music include Dawn of Carlos Gomes and Carta Celeste by Almeida Prado. Unlike The Planets by Gustav Holst -who between 1914 and 1916 composed a symphonical tribute to the solar system based on astrology- Almeida Prado composed a symphony that is not limited to the world of planets, penetrating the deep cosmos of galaxies.

    The first prototype of a hybrid electric fuel cell bus developed with Brazilian technology is unveiled. It is a 12 m urban-type, low-floor, air-conditioned bus that possesses three doors, air suspension, 29 seats and reversible wheelchair site. The bus body was built based on a double-deck type monoblock vehicle that is able to sustain important load on its roof. This allowed positioning of the type 3 hydrogen tanks and the low weight traction batteries on the roof of the vehicles without dynamic stabilization problems. A novel hybrid energy configuration was designed in such a way that the low-power (77 kWe) fuel cell works on steady-state operation mode, not responding directly to the traction motor load demand. The rate of kinetic energy regeneration upon breaking was optimized by the use of an electric hybrid system with predominance of batteries and also by utilizing supercapacitors. The electric-electronic devices and the security control softwares for the auxiliary and traction systems were developed in-house. The innovative hybrid-electric traction system configuration led to the possibility to decrease the fuel cell power, with positive impact on weight and system volume reduction, as well as to significantly decrease the hydrogen consumption.

    The purpose of this study was to evaluate the body composition, dietary intake, use of nutritional supplements, and biochemical status of 8 Brazilian male elite swimmers, aged 18-21 years, participants at a national swimming competition. Data from the athletes were obtained through a 4-day food record, a fasting blood sample, and anthropometric measurements. The anthropometric results showed that body composition was compatible with sport category. The dietary assessment showed an adequate ingestion of calories, vitamins, and mineral, with the exception of calcium, for which only half of the sample reached the recommendation. The results also indicated low carbohydrate and high protein and cholesterol intakes. Of the swimmers, 62.5% and 25% consumed synthetic aminoacids and antioxidants supplements, respectively. The biochemical indices of the nutritional status were within normal limits in all swimmers, with the exception of creatine-kinase, which was above the recommended level, indicating muscle degradation probably due to poor carbohydrate intake. In conclusion, the results suggest the importance of nutritional education to promote a balanced intake, provide all nutrients in optimal amounts, inhibit unnecessary ingestion of nutritional supplements, maintain ideal performance, and improve the swimmers' health status.

    Full Text Available Abstract Professional dental auxiliaries emerged in the early 20th century in the United States of America and quickly spread to Europe and other regions of the world. In Brazil, however, oral health technicians (OHTs, who occupy a similar role as dental hygienists, had a long journey before the occupation achieved legal recognition: Brazilian Law 11.889, which regulates this occupation in the country, was only enacted in 2008. The aim of this paper is to review the literature on the professionalization of OHTs, highlighting the triggering, limiting and conflicting aspects that exerted an influence on the historical progress of these professionals in Brazil. We have tested Abbott’s and Larson’s theory on professionalization, against the history of OHTs. A number of different dental corporative interests exerted an influence over professionalization, especially in discussions regarding the permissible activities of these professionals in the oral cavity of patients. With primary health care advances in Brazil, the importance of these professionals has once again come to the forefront. This seems to be a key point in the consolidation of OHTs in the area of human resources for health in Brazil.

    Full Text Available The disposition effect predicts that investors tend to sell winning stocks too soon and ride losing stocks too long. Despite the wide range of research evidence about this issue, the reasons that lead investors to act this way are still subject to much controversy between rational and behavioral explanations. In this article, the main goal was to test two competing behavioral motivations to justify the disposition effect: prospect theory and mean reversion bias. To achieve it, an analysis of monthly transactions for a sample of 51 Brazilian equity funds from 2002 to 2008 was conducted and regression models with qualitative dependent variables were estimated in order to set the probability of a manager to realize a capital gain or loss as a function of the stock return. The results brought evidence that prospect theory seems to guide the decision-making process of the managers, but the hypothesis that the disposition effect is due to mean reversion bias could not be confirmed.

The objective of this study is to discuss the potential and perspectives of the Brazilian Database on Orofacial Clefts. Methods. From 2008 to 2010, clinical and familial information on 370 subjects was collected by geneticists in eight different services. Data was centrally processed using an international system for case classification and coding. Results. Cleft lip with cleft palate amounted to 198 (53.5%, cleft palate to 99 (26.8%, and cleft lip to 73 (19.7% cases. Parental consanguinity was present in 5.7% and familial history of cleft was present in 26.3% subjects. Rate of associated major plus minor defects was 48% and syndromic cases amounted to 25% of the samples. Conclusions. Overall results corroborate the literature. Adopted tools are user friendly and could be incorporated into routine patient care. The BDOC exemplifies a network for clinical and genetic research. The data may be useful to develop and improve personalized treatment, family planning, and healthcare policies. This experience should be of interest for geneticists, laboratory-based researchers, and clinicians entrusted with OC worldwide.

Some 2000 fish species and 40 species of free-living copepods are known to occur in Amazonia. The free-living forms serve as food for most larval fishes and some adults, but they also transmit several parasites including representatives of the nematode family Camallanidae. About three dozen species of parasitic copepods have been described from the Brazilian Amazon. Females of Amazonian parasitic copepods are found on skin, gill filaments, gill rakers or within the nasal fossae. Parasitic copepods are found on fishes that are from a few millimeters long up to those over 2 m in length and they are usually quite host specific. All have body pigmentation in different patterns and colors (frequently blues, such as cerulean, cobalt, spectrum, smalt or campanula). It is suggested that the coloration serves to attract specific host fish. Copepods have evolved adaptations for attachment and feeding, especially in the second antennae and endopods. Examples of progenesis, phoresis and commensalism are shown. Some species produce pathology such as a tourniquet effect, hyperplasia, blood loss and anemia, and can kill fishes by limiting their respiration.

    This article describes the configuration of the scientific field in Brazil, characterizing the scientific communities in every major area of knowledge in terms of installed capacity, ability to train new researchers, and capacity for academic production. Empirical data from several sources of information are used to characterize the different communities. Articulating the theoretical contributions of Pierre Bourdieu, Ludwik Fleck, and Thomas Kuhn, the following types of capital are analyzed for each community: social capital (scientific prestige), symbolic capital (dominant paradigm), political capital (leadership in S & T policy), and economic capital (resources). Scientific prestige is analyzed by taking into account the volume of production, activity index, citations, and other indicators. To characterize symbolic capital, the dominant paradigms that distinguish the natural sciences, the humanities, applied sciences, and technology development are analyzed theoretically. Political capital is measured by presidency in one of the main agencies in the S & T national system, and research resources and fellowships define the economic capital. The article discusses the composition of these different types of capital and their correspondence to structural capacities in various communities with the aim of describing the configuration of the Brazilian scientific field.

    Objective To evaluate whether there is any preference for citing journals from other countries to the detriment of Brazilian journals, in three Brazilian orthopedics journals. 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

    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.

  1. The Corporate Governance of Privately Controlled Brazilian Firms

    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.

    Full Text Available 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.

    Full Text Available Propolis is a complex honeybee product with resinous aspect, containing plant exudates and beeswax. Their color, texture, and chemical composition vary, depending on the location of the hives and local flora. The most studied Brazilian propolis is the green (alecrim-do-campo type, which contains mainly prenylated phenylpropanoids and caffeoylquinic acids. Other types of propolis are produced in Brazil, some with red color, others brown, grey, or black. The aim of the present work was to determine the chemical profiles of alcohol and chloroform extracts of eight samples of propolis, corresponding to six Brazilian regions. Methanol and chloroform extracts were obtained and analyzed by HPLC/DAD/ESI/MS and GC/MS. Two chemical profiles were recognized among the samples analyzed: (1 black Brazilian propolis, characterized chiefly by flavanones and glycosyl flavones, stemming from Picos (Piauí state and Pirenópolis (Goiás state; (2 green Brazilian propolis, characterized by prenylated phenylpropanoids and caffeoylquinic acids, stemming from Cabo Verde (Bahia state, Lavras and Mira Bela (Minas Gerais state, Pariquera-Açu and Bauru (São Paulo state, and Ponta Grossa (Paraná state. The present work represents the first report of prenylated flavonoids in Brazilian propolis and schaftoside (apigenin-8-C-glucosyl-6-C-arabinose in green propolis.

    The Brazilian scientific production saw more than a four-fold increase from the 1990s onwards. The aim of this study was to evaluate the evolution of scientific production by Brazilian clinical neuroscientists over the last 10 years. A search in the PubMed identified 295 clinical neuroscientists and their publications. Brazilian production corresponded to 2.37% of the papers published by the 20 indexed periodicals that regularly publish clinical neuroscience research. If only the first and last two years are compared, there was a real growth of 75.1%. More than 40% of the Brazilian papers were published in Arquivos de Neuro-Psiquiatria, the official journal of the Brazilian Academy of Neurology. When only those periodicals with impact factor higher than one are considered, the percentage falls to 0.86% in the whole 10-year period, but attains 1.23% in 2004. Epilepsy and infectious diseases were the sub-areas with the highest scientific production.

    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.

    Full Text Available OBJECTIVES: To identify the most cited articles in general surgery published by Brazilian authors. INTRODUCTION: There are several ways for the international community to recognize the quality of a scientific article. Although controversial, the most widely used and reliable methodology to identify the importance of an article is citation analysis. METHODS: A search using the Institute for Scientific Information citation database (Science Citation Index Expanded was performed to identify highly cited Brazilian papers published in twenty-six highly cited general surgery journals, selected based on their elevated impact factors, from 1970 to 2009. Further analysis was done on the 65 most-cited papers. RESULTS: We identified 1,713 Brazilian articles, from which nine papers emerged as classics (more than 100 citations received. For the Brazilian contributions, a total increase of about 21-fold was evident between 1970 and 2009. Although several topics were covered, articles covering trauma, oncology and organ transplantation were the most cited. The majority of classic studies were done with international cooperation. CONCLUSIONS: This study identified the most influential Brazilian articles published in internationally renowned general surgery journals.

    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.

  12. Systematic risk variations (beta convertible debenture brazilian companies

    Renata Drumond Pinto Coelho Antonino

    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 The Brazilian party system presents a paradox. Although the Workers Party (PT and the Brazilian Social Democratic Party (PSDB have controlled presidential elections for the last 20 years, their force at the other levels of electoral competition has not grown. The objective of this study is to undertake a discussion of this situation through the 2014 general elections. 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.

    2004-12-01

    Full Text Available Brazil was the first developing country to provide free, universal access to antiretroviral treatment for AIDS patients. The Brazilian experience thus provides the first evidence regarding the impact of such treatment on the survival of perinatally acquired AIDS cases in the developing world. MATERIAL AND METHODS: This retrospective cohort study used medical record reviews to examine characteristics and trends in the survival of a representative sample of 914 perinatally acquired AIDS cases in 10 Brazilian cities diagnosed between 1983 and 1998. RESULTS: Survival time increased steadily and substantially. Whereas half of the children died within 20 months of diagnosis at the beginning of the epidemic, 75% of children diagnosed in 1997 and 1998 were still alive after four years of follow-up. CONCLUSIONS: Advances in management and treatment have made a great difference in the survival of Brazilian children with AIDS. These results argue strongly for making such treatment available to children in the entire developing world.

    Full Text Available In Brazil, many plants are used as tonic, fortifier, aphrodisiac, anti-stress, among other uses that are similar to the indications of an adaptogen. In general, such plants are used unspecifically, in situations of stress and fatigue, in the recovery after a previous pathological or debilitating state, or simply aiming at the maintenance of a healthy state. This article discusses the popular terms employed in the Brazilian folk medicine for the plants with this profile, their particularities and limitations. The article also discusses the possible mechanisms of action of an adaptogen and compares the main Brazilian plants used for that purpose: guarana (Paullinia cupana Kunth, family Sapindaceae, muirapuama (Ptychopetalum olacoides Benth., Olacaceae, catuaba (Anemopaegma arvense (Vell.

    Full Text Available Foreign direct investment (FDI has become increasingly important for the Brazilian economy: the ratio of FDI inflow to the country's gross domestic product (GDP increased from a 0.6% average in the 1980's to 2.5% from 2001 to 2010, according to data from UNCTAD. However, there is great inequality in the distribution of this investment among Brazilian federation units. This study aims at investigating the determining factors for the location of foreign direct investment across Brazilian states, based on an econometric study with panel data for the years 1995, 2000 and 2005. The results showed that foreign investment responded positively to consumer market size, quality of labor and transport infrastructure, but negatively to cost of labor and tax burden.

    Full Text Available The sense of community is an important construct for assessing the individual’s relationship with his/her community context. This study aims to adapt the Sense of Community Index for Brazilian Children and verify its psychometric properties in this sample. The participants are 1,736 Brazilian children between 8 and 13 years old (53.3% girls. Exploratory factor analysis indicated a two-factor solution (Positive bond with community and Community neighbors’ relationships, with 47.9% of explained variance. Scale reliability was adequate (Cronbach’s α = .78 and confirmatory factor analysis presented good fit indices (CFA > .95 and RMSEA < .05. Multigroup analysis indicated that the items have the same meanings regarding sex and age, and that the latent factors means are comparable regarding sex, but not for age. The proposed model of the instrument is adequate and can be used in future studies with Brazilian children.

    2015-01-01

    Elections, specially in countries such as Brazil, with an electorate of the order of 100 million people, yield large-scale data-sets embodying valuable information on the dynamics through which individuals influence each other and make choices. In this work we perform an extensive analysis of data sets available for Brazilian proportional elections of legislators and city councilors throughout the period 1970-2014, which embraces two distinct political regimes: a military regime followed by a democratic one. We perform a comparative analysis of elections for legislative positions, in different states and years, through the distribution p(v) of the number of candidates receiving v votes. We show the impact of the different political regimes on the vote distributions. Although p(v) has a common shape, with a scaling behavior, quantitative details change over time and from one electorate to another. In order to interpret the observed features, we propose a multi-species model consisting in a system of nonlinear differential equations, with values of the parameters that reflect the heterogeneity of candidates. In its simplest setting, the model can not explain the cutoff, formed by the most voted candidates, whose success is determined mainly by their peculiar, intrinsic characteristics, such as previous publicity. However, the modeling allows to interpret the scaling of p(v), yielding a predictor of the degree of feedback in the interactions of the electorate. Knowledge of the feedback is relevant beyond the context of elections, since a similar interactivity may occur for other social contagion processes in the same population.

    Rodolpho Repullo Junior

    Full Text Available CONTEXT: Many authors have emphasized the importance of worker strength through unionized organizations, in relation to the improvement of working procedures, and have reported on the decisiveness of labor movement actions in achieving modifications within the field of work and health. OBJECTIVE: To describe the ways in which Brazilian unions have tried to intervene in health-illness and work processes, identifying the existence of commonality in union actions in this field. TYPE OF STUDY: Qualitative study. SETTING: Postgraduate Program, Environmental Health Department, Faculdade de Saúde Pública, Universidade de São Paulo, São Paulo, Brazil. METHODS: Union health advisers and directors were interviewed. Documents relating to union action towards protecting workers' health were collected and analyzed. RESULTS: Unions articulate actions regarding workers' health of a technical and political nature that involve many aspects and high complexity. These have been divided into thematic categories for better analysis. DISCUSSION: Union actions regarding workers' health in Brazil are restricted to some unions, located mainly in the southern, southeastern and northeastern regions of the country. Nonetheless, the unions undertaking such actions represent many professions of great economic and political importance. CONCLUSIONS: The recent changes in health and safety at work regulations, recognition of professional diseases, creation of workers' health services and programs within the unified health system, and operational improvements in companies' specialized safety and occupational medicine services, all basically result from union action. There is commonality of union action in this field in its seeking of technical and political strengthening for all workers and their general and local representation. This has the objective of benefiting collective bargaining between employers and workers. Inter-institutional action on behalf of workers' rights

  1. Hygienic behaviour in Brazilian stingless bees

    Full Text Available Social insects have many defence mechanisms against pests and pathogens. One of these is hygienic behaviour, which has been studied in detail in the honey bee, Apis mellifera. Hygienic honey bee workers remove dead and diseased larvae and pupae from sealed brood cells, thereby reducing disease transfer within the colony. Stingless bees, Meliponini, also rear broods in sealed cells. We investigated hygienic behaviour in three species of Brazilian stingless bees (Melipona scutellaris, Scaptotrigona depilis, Tetragonisca angustula in response to freeze-killed brood. All three species had high mean levels of freeze-killed brood removal after 48 h ∼99% in M. scutellaris, 80% in S. depilis and 62% in T. angustula (N=8 colonies per species; three trials per colony. These levels are greater than in unselected honey bee populations, ∼46%. In S. depilis there was also considerable intercolony variation, ranging from 27% to 100% removal after 2 days. Interestingly, in the S. depilis colony with the slowest removal of freeze-killed brood, 15% of the adult bees emerging from their cells had shrivelled wings indicating a disease or disorder, which is as yet unidentified. Although the gross symptoms resembled the effects of deformed wing virus in the honey bee, this virus was not detected in the samples. When brood comb from the diseased colony was introduced to the other S. depilis colonies, there was a significant negative correlation between freeze-killed brood removal and the emergence of deformed worker bees (P=0.001, and a positive correlation with the cleaning out of brood cells (P=0.0008. This shows that the more hygienic colonies were detecting and removing unhealthy brood prior to adult emergence. Our results indicate that hygienic behaviour may play an important role in colony health in stingless bees. The low levels of disease normally seen in stingless bees may be because they have effective mechanisms of disease management, not because

    Background: A registry assessing the care of hypertensive patients in daily clinical practice in public and private centers in various Brazilian regions has not been conducted to date. Such analysis is important to elucidate the effectiveness of this care. Objective: To document the current clinical practice for the treatment of hypertension with identification of the profile of requested tests, type of administered treatment, level of blood pressure (BP) control, and adherence to treatment. Methods: National, observational, prospective, and multicenter study that will include patients older than 18 years with hypertension for at least 4 weeks, following up in public and private centers and after signing a consent form. The study will exclude patients undergoing dialysis, hospitalized in the previous 30 days, with class III or IV heart failure, pregnant or nursing, with severe liver disease, stroke or acute myocardial infarction in the past 30 days, or with diseases with a survival prognosis < 1 year.

    An increasing volume of publications has addressed the role of tectonics in inland areas of northern Brazil during the Neogene and Quaternary, despite its location in a passive margin. Hence, northern South America plate in this time interval might have not been as passive as usually regarded. This proposal needs further support, particularly including field data. In this work, we applied an integrated approach to reveal tectonic structures in Miocene and late Quaternary strata in a coastal area of the Amazonas lowland. The investigation, undertaken in Marajó Island, mouth of the Amazonas River, consisted of shallow sub-surface geophysical data including vertical electric sounding and ground penetrating radar. These methods were combined with morphostructural analysis and sedimentological/stratigraphic data from shallow cores and a few outcrops. The results revealed two stratigraphic units, a lower one with Miocene age, and an upper one of Late Pleistocene-Holocene age. An abundance of faults and folds were recorded in the Miocene deposits and, to a minor extent, in overlying Late Pleistocene-Holocene strata. In addition to characterize these structures, we discuss their origin, considering three potential mechanisms: Andean tectonics, gravity tectonics related to sediment loading in the Amazon Fan, and rifting at the continental margin. Amongst these hypotheses, the most likely is that the faults and folds recorded in Marajó Island reflect tectonics associated with the history of continental rifting that gave rise to the South Atlantic Ocean. This study supports sediment deposition influenced by transpression and transtension associated with strike-slip divergence along the northern Equatorial Brazilian margin in the Miocene and Late Pleistocene-Holocene. This work records tectonic evidence only for the uppermost few ten of meters of this sedimentary succession. However, available geological data indicate a thickness of up to 6 km, which is remarkably thick for

    Full Text Available INTRODUCTION: aerobic fitness is considered one of the most important components of health-related physical fitness, with low levels related to increased risk of premature death from all causes, especially cardiovascular diseases. OBJECTIVE: to identify the characteristics of adolescents at higher risk of low levels of aerobic fitness. METHODS: the study included 696 adolescents 15-17 years of age enrolled in public high schools of Florianópolis, southern Brazil. This cross-sectional epidemiological study was conducted in Florianópolis, Santa Catarina, Brazil. Aerobic fitness was measured using the modified Canadian Aerobic Fitness Test mCAFT. Sociodemographic gender, age, school grade, paternal and maternal schooling, socioeconomic status, and anthropometric variables body weight, height, triceps and subscapular skinfold thickness, sexual maturation, physical activity, sedentary behavior, and eating habits were collected. RESULTS: it was found that 31.5% of adolescents had low aerobic fitness levels, being higher in boys 49.2% compared to girls 20.6%. Moreover, girls with sedentary behavior, overweight and high body fat percentage were the groups most likely to have inadequate aerobic fitness. In males, the groups most likely to have inadequate aerobic fitness were those whose parents studied more than eight years, those with low levels of physical activity, and those with inadequate nutrition and excessive body fat. CONCLUSION: low aerobic fitness levels were present in one third of adolescents and was more prevalent in boys. Lifestyle changes, including replacement of sedentary behaviors by physical and sport activities , may assist in improving the aerobic fitness of Brazilian adolescents.

    ABSTRACT Social insects have many defence mechanisms against pests and pathogens. One of these is hygienic behaviour, which has been studied in detail in the honey bee, Apis mellifera. Hygienic honey bee workers remove dead and diseased larvae and pupae from sealed brood cells, thereby reducing disease transfer within the colony. Stingless bees, Meliponini, also rear broods in sealed cells. We investigated hygienic behaviour in three species of Brazilian stingless bees (Melipona scutellaris, Scaptotrigona depilis, Tetragonisca angustula) in response to freeze-killed brood. All three species had high mean levels of freeze-killed brood removal after 48 h ∼99% in M. scutellaris, 80% in S. depilis and 62% in T. angustula (N=8 colonies per species; three trials per colony). These levels are greater than in unselected honey bee populations, ∼46%. In S. depilis there was also considerable intercolony variation, ranging from 27% to 100% removal after 2 days. Interestingly, in the S. depilis colony with the slowest removal of freeze-killed brood, 15% of the adult bees emerging from their cells had shrivelled wings indicating a disease or disorder, which is as yet unidentified. Although the gross symptoms resembled the effects of deformed wing virus in the honey bee, this virus was not detected in the samples. When brood comb from the diseased colony was introduced to the other S. depilis colonies, there was a significant negative correlation between freeze-killed brood removal and the emergence of deformed worker bees (P=0.001), and a positive correlation with the cleaning out of brood cells (P=0.0008). This shows that the more hygienic colonies were detecting and removing unhealthy brood prior to adult emergence. Our results indicate that hygienic behaviour may play an important role in colony health in stingless bees. The low levels of disease normally seen in stingless bees may be because they have effective mechanisms of disease management, not because they lack

    Full Text Available This paper used a bibliometric research to compare and draw an overview of scientific production on forensic Accounting area, published in Brazilian journals in the period between 2005 and 2014 regarding the number of publications, characteristics of the authors, published topics, methodologies and its subclasses and and journals that publish in the area. It was collected and analyzed 48 articles the information as variation of year publication, subjects treated by, authors and their characteristics, Qualis classification, methodology, methodological nature applied, description of the empirical method and journals that have published articles in the area. Descriptive statistics were used to analyze the data. As a result it was found that the main subjects considered are related to the "work of the expert accountant", "expert opinion" and expertise within the context of judicial proceedings. Regarding the authors the vast majority produce only one article in the area over the 10 years examined, and these authors, 64,58% were male. The Qualis extract of the articles is located between C and B1, indicating that the publications fail to achieve high standards of academic quality. On the methodology it was found that 91.67% are empirical research, of these 78% ranked in quantitative or qualitative and 83% are publications opting for descriptive techniques. Regarding the journals, it was found that 50% have only one publication on "forensic accounting", indicating that it is not repeated exposure, as the number of publications ranging from two to five in the other 50% of journals. It is concluded that scientific research in forensic accounting area are still relatively embryonic, lacking certain softening related to the subjects, number of publications and quality of intellectual production.

    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.

    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.

    Débora Krischke Leitão

    Full Text Available This article discusses the consumption of Brazilian products - especially fashion and clothing - in France as a way of consuming the exotic. Drawing on ten months of fieldwork in France, I engage data collected there with my experience from previous research carried out in Brazil. Firstly, this article discusses exoticism, a topic that invariably broaches a debate about identity and alterity. Then, some particularities of "consuming the other" in French discourses about Brazilian products are analyzed. Finally, I conclude that the construction of Brazilian fashion as exoticism is simultaneously situated in the French imaginary about the Brazilian other and in the very Brazilian production of garment fashion.

    Full text: Coffee is one of the most popular and consumed beverages worldwide. Consumers can make the beverage from different types of coffee such as ground coffee, instant coffee or grinding roasted coffee beans. Each type of coffee leads to different characteristics in flavor and scent. The aim of this work is to perform an elemental analysis of ground coffee and roasted coffee beans. To that end, eight popular Brazilian ground coffee brands have been chosen to make a comparative study among brands. One of these brands was selected for a complete study of the beverage preparation process. This same brand offers packages of roasted coffee beans, which allowed the elemental comparison between ground coffee and roasted coffee beans. Roasted coffee beans were ground with a pestle and mortar. The beverage was prepared using a typical coffee pot. The spent and liquid coffees were submitted to a heat treatment and subsequently homogenized and pressed into pellets. The filters used in the coffee pot were analyzed as well. For micro-PIXE studies, coffee beans were cut in different parts for analysis. Samples of ground coffee and roasted coffee beans (grind) were analyzed by PIXE, while light elements like C, O and N were analyzed by RBS (Rutherford Backscattering Spectrometry). The roasted coffee beans were analyzed by micro-PIXE to check the elemental distribution in the beans. The elements found in powder coffee were Mg, AI, Si, P, S, CI, K, Ca, Ti, Mn, Fe, Cu, Zn and Rb. Potassium is the element with higher concentration, while Ti and Zn are trace elements. AI, Si and Ti showed the same concentration for all brands. Potassium and chlorine have high solubility, and about 80% of their concentration is transferred from the powder to the beverage during the infusion. Mg, P, CI, K, Mn, Fe, Zn and Rb showed significant variation between ground coffee and roasted coffee beans. The elemental maps show that potassium and phosphorus are correlated, and iron appears in particular

    Full Text Available ABSTRACT OBJECTIVE To estimate the prevalences of tobacco use, tobacco experimentation, and frequent smoking among Brazilian adolescents. METHODS We evaluated participants of the cross-sectional, nation-wide, school-based Study of Cardiovascular Risks in Adolescents (ERICA, which included 12- to 17-year-old adolescents from municipalities of over 100 thousand inhabitants. The study sample had a clustered, stratified design and was representative of the whole country, its geographical regions, and all 27 state capitals. The information was obtained with self-administered questionnaires. Tobacco experimentation was defined as having tried cigarettes at least once in life. Adolescents who had smoked on at least one day over the previous 30 days were considered current cigarette smokers. Having smoked cigarettes for at least seven consecutive days was an indicator for regular consumption of tobacco. Considering the complex sampling design, prevalences and 95% confidence intervals were estimated according to sociodemographic and socio-environmental characteristics. RESULTS We evaluated 74,589 adolescents. Among these, 18.5% (95%CI 17.7-19.4 had smoked at least once in life, 5.7% (95%CI 5.3-6.2 smoked at the time of the research, and 2.5% (95%CI 2.2-2.8 smoked often. Adolescents aged 15 to 17 years had higher prevalences for all indicators than those aged 12 to 14 years. The prevalences did not differ significantly between sexes. The highest prevalences were found in the South region and the lowest ones, in the Northeast region. Regardless of sex, the prevalences were found to be higher for adolescents who had had paid jobs, who lived with only one parent, and who reported having been in contact with smokers either inside or outside their homes. Female public school adolescents were found to smoke more than the ones from private schools. CONCLUSIONS Tobacco use among adolescents is still a challenge.

    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.

Firstly, we highlighted the concerns of Brazilian managers in respect to the coming years, and to identify the current strategic approach of prominent companies in the Brazilian market. Secondly, we identified possible strategies for internationalization, particularly in the context of Latin America. The results of two surveys were used: one prospecting management trends by 2015 and another consisting of a sample of 541 companies that participate in a national survey in which HR managers answered a questionnaire. Among the results, it is noteworthy that the main issues of concern for Brazilian managers in the coming years. We found most the companies concerned with these challenges in the industries of information technology, iron and steel, and health services. Forty-nine of a total of 541 companies intend to internationalize, 17 of them towards Latin American. Their profile characterization allowed us to divide them into two groups: those focusing on the local needs of Latin American, and those looking to meet the expanding needs of Brazil or the country of their parent company.

    The use of natural compounds from biodiversity, as well as ethnobotanical knowledge, for the development of new drugs is the gate leading to support the conservation of natural resources in developing countries. Recent technological advances and the development of new methods are revolutionizing the screening of natural products and offer a unique opportunity to replace natural products as major source of drug leads. Over the past decades, the Brazilian government established a legislation aiming to grant patent protection in all technological fields. The Convention on Biological Diversity, an international agreement that recognizes the sovereign rights of States over their natural resources, and the Brazilian legislation (Decreto n degree 2186-12/01) set for legislative, administrative or policy measures regarding the share of research and product development benefits could be the key for progress in issues related to rational employment of the Brazilian biodiversity and economy, but are far from being effective. Based on literature review, this article provides a brief description of the Brazilian legislation policy regarding intellectual property and biodiversity access, places natural drug discovery in context, analyzes patent cases and highlights critical key issues responsible for the drawback of the whole process that has a direct impact on industrial and research development, nature protection and benefit share with our society.

    Full Text Available OBJECTIVE: 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. METHODS: 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. RESULTS: 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.

    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.

    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.

    Background Quotations in Brazilian journals are mainly obtained from national articles (articles from Brazilian journals); thus, it is essential to determine how frequently these articles reference Brazilian journals. Objective This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. Method All references for articles published in Fisioterapia em Movimento, Fisioterapia e Pesquisa and Revista Brasileira de Fisioterapia between 2010 and 2012 were evaluated. In particular, the numbers of national articles and international articles (articles from international journals) cited in these references were determined. Results A total of 13,009 references cited by 456 articles were analyzed, and 2,924 (22.47%) of the cited works were national articles. There were no significant differences among the three examined years. A total of 36 (7.89%) articles did not cite national articles, whereas 65 (13.25%) articles cited more national articles than international articles. Conclusion On average, 22.47% of the works cited by the evaluated articles were national articles. No significant differences were detected among the three analyzed years. PMID:24675917

    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.

    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.

  10. PERSPECTIVE: Learning from the Brazilian biofuel experience

    Wang, Michael

    2006-11-01

    In the article `The ethanol program in Brazil' [1] José Goldemberg summarizes the key features of Brazil's sugarcane ethanol program—the most successful biofuel program in the world so far. In fact, as of 2005, Brazil was the world's largest producer of fuel ethanol. In addition to providing 40% of its gasoline market with ethanol, Brazil exports a significant amount of ethanol to Europe, Japan, and the United States. The success of the program is attributed to a variety of factors, including supportive governmental policies and favorable natural conditions (such as a tropical climate with abundant rainfall and high temperatures). As the article points out, in the early stages of the Brazilian ethanol program, the Brazilian government provided loans to sugarcane growers and ethanol producers (in most cases, they are the same people) to encourage sugarcane and ethanol production. Thereafter, ethanol prices were regulated to ensure that producers can economically sustain production and consumers can benefit from using ethanol. Over time, Brazil was able to achieve a price for ethanol that is lower than that for gasoline, on the basis of energy content. This lower cost is largely driving the widespread use of ethanol instead of gasoline by consumers in Brazil. In the United States, if owners of E85 flexible-fuel vehicles (FFVs) are expected to use E85 instead of gasoline in their FFVs, E85 will have to be priced competitively against gasoline on an energy-content basis. Compared with corn-based or sugar beet-based ethanol, Brazil's sugarcane-based ethanol yields considerably more favorable results in terms of energy balance and reductions in greenhouse gas emissions. These results are primarily due to (i) the dramatic increase of sugarcane yield in Brazil in the past 25 years and (ii) the use of bagasse instead of fossil fuels in ethanol plants to provide the heat needed for ethanol plant operations and to generate electricity for export to electric grids

  11. Brazilian sandy beach macrofauna production: a review

    Full Text Available The state of the art of the studies on the production of Brazilian sandy beach macrofauna was analyzed on the basis of the data available in the literature. For this purpose, the representativeness of the production dataset was examined by latitudinal distribution, degree of exposure and morphodynamic state of beaches, taxonomic groups, and methods employed. A descriptive analysis was, further, made to investigate the trends in production of the more representative taxonomic groups and species of sandy beach macrofauna. A total of 69 macrofauna annual production estimates were obtained for 38 populations from 25 studies carried out between 22º56'S and 32º20'S. Production estimates were restricted to populations on beaches located on the southern and southeastern Brazilian coast. Most of the populations in the dataset inhabit exposed dissipative sandy beaches and are mainly represented by mollusks and crustaceans, with a smaller number of polychaetes. The trends in production among taxonomic groups follow a similar pattern to that observed on beaches throughout the world, with high values for bivalves and decapods. The high turnover rate (P/B ratio of the latter was due to the presence of several populations of the mole crab Emerita brasiliensis, which can attain high values of productivity, in the dataset. Most of the studies focus on the comparison of production and, especially, of P/B ratio according to life history traits in populations of the same species/taxonomic group. Despite the importance of life history-production studies, other approaches, such as the effect of man-induce disturbances on the macrofauna, should be undertaken in these threatened environments.O estado da arte dos estudos de produção da macrofauna de praias arenosas brasileiras foi analisado a partir de informações disponíveis na literatura. Para essa finalidade, a representatividade dos dados de produção foi examinada de acordo com a distribuição latitudinal

    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.

    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.

    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). Besides this NPP, in the National Energy Program is previewed the installation of four more plants, by 2030. In November 2008, CNEN launched the Project RBMN (Repository for Low and Intermediate-Level Radioactive Wastes), which 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. (authors)

    Full Text Available Abstract Background Antioxidant nutrient intake and the lesser formation of free radicals seem to contribute to chronic diseases. The aim of the present study was to evaluate the intake profile of the main dietary antioxidants in a representative sample of the adult Brazilian population and discuss the main consequences of a low intake of these micronutrients on overall health. Methods The sample comprised 2344 individuals aged 40 years or older from 150 cities and was based on a probabilistic sample from official data. The research was conducted through in-home interviews administered by a team trained for this purpose. Dietary intake information was obtained through 24-h recall. The Nutrition Data System for Research software program was used to analyze data on the intake of vitamins A, C and E, selenium and zinc, which was compared to Dietary Reference Intakes (DRIs. Differences in intake according to sex, anthropometrics, socioeconomic status and region were also evaluated. The SPSS statistical package (version 13 was used for the statistical analysis. P-values Results Higher proportions of low intake in relation to recommended values were found for vitamin E (99.7%, vitamin A (92.4% and vitamin C (85.1% in both genders. Intake variations were found between different regions, which may reflect cultural habits. Conclusion These results should lead to the development of public health policies that encourage educational strategies for improving the intake of micronutrients, which are essential to overall health and prevention of non-communicable diseases.

    1987-10-03

    Brazilian purpuric fever (BPF) is a fulminant, often fatal childhood illness that was first recognised in 1984. An outbreak in Serrana, São Paulo State in March to May, 1986, resulted in 11 cases. Haemophilus aegyptius was isolated from normally sterile body fluids in 10 children (9 from blood and 1 from cerebrospinal fluid contaminated with blood), consistent with a direct role for H aegyptius in the pathogenesis of BPF. The ability to define cases by positive blood cultures permitted an evaluation of the spectrum of illness of this disease. 5 culture-positive cases were clinically similar to those previously described; the other 5 had milder illness without petechial or purpuric skin manifestations at the time the bacterium was isolated. Blood cultures were a sensitive means of diagnosing BPF; cultures were positive in 5 of 6 patients that met the full clinical case definition. Treatment of conjunctivitis did not appear to prevent BPF. However, children treated with intravenous antimicrobials early in the systemic illness had a trend toward better survival, suggesting that early therapy may prevent progression of the illness.

    The objective of this research was to analyze the organizational culture of a Brazilian public hospital. It is a descriptive study with quantitative approach of data, developed in a public hospital of São Paulo State, Brazil. The sample was composed by 52 nurses and 146 nursing technicians and auxiliaries. Data were collected from January to June 2011 using the Brazilian Instrument for Assessing Organizational Culture - IBACO. The analysis of the organizational values showed the existence of hierarchical rigidity and centralization of power within the institution, as well as individualism and competition, which hinders teamwork. The values concerning workers' well-being, satisfaction and motivation were not highly valued. In regard to organizational practices, the promotion of interpersonal relationship, continuous education, and rewarding practices were not valued either. It becomes apparent that traditional models of work organization support work practices and determine the organizational culture of the hospital.

    2012-10-01

    This article presents a model of the healthcare value chain which consists of a schematic representation of the Brazilian healthcare system. The proposed model is adapted for the Brazilian reality and has the scope and flexibility for use in academic activities and analysis of the healthcare sector in Brazil. It places emphasis on three components: the main activities of the value chain, grouped in vertical and horizontal links; the mission of each link and the main value chain flows. The proposed model consists of six vertical and three horizontal links, amounting to nine. These are: knowledge development; supply of products and technologies; healthcare services; financial intermediation; healthcare financing; healthcare consumption; regulation; distribution of healthcare products; and complementary and support services. Four flows can be used to analyze the value chain: knowledge and innovation; products and services; financial; and information.

    Full Text Available Seaweeds are used directly as food or applied indirectly as texturing agents with gelling and thickening properties (carrageenan, agar and alginates in many industries. They can also be used as fertilizers, animal feed, biomass for fuel, cosmetics and a source of pharmaceuticals, among other applications. The aquaculture of macroalgae is an alternative for producing raw material. Brazil has a coastline with numerous locations suitable for this endeavor. However, despite the known economical and social relevance of seaweed cultivation, Brazilians do not have tradition of using edible seaweeds. In general, the raw material for indirect use (e.g., as a texturing agent is imported. Consequently, seaweed aquaculture is still incipient in Brazil. This contribution presents data and information about macroalgae cultivation on commercial and experimental scales performed on the Southern and Southeastern Brazilian Coastline, as well as a brief overview of research related to some species cultivated in the last decade.

    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.

    2016-06-01

    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.

    Hydrogen is a promising energy carrier, which potentially could replace the fossil fuels used in the transportation and distributed energy sector of Brazilian economy. Fossil fuels are polluting by carbogenic emissions from their combustion, being so co-responsible for present global warming. However, no large scale, cost-effective, environmentally non-carbogenic hydrogen production process is currently available for commercialization. There are feasible possibilities to use electrolysis as one of the main sources of hydrogen, especially thinking on combination with renewable sources of energy, mainly eolic and solar. In this work some perspectives for Brazilian energy context is presented, where electrolysis combined with renewable power source and fuel cell power generation would be a good basis to improve the distributed energy supply for remote areas, where the electricity grid is not present or is deficient.

    Full Text Available The goal of this study was to analyze brazilian franchises internationalization through a case study, in order to identify the factors that influence internationalization, the adaptations of marketing strategies and main barriers and challenges of brazilian franchises internationalization. A qualitative exploratory research was developed through the case study method. The information was colected via observation and semi-structured interviews with managers in charge of international expansion of two companies. A comparative analysis between obtained data and the theoretical background was made. The results found showed that the studied companies expanded internationally due to external demands and the desire to explore new markets. Changes in marketing strategies were made in different degrees, and communication was the element that suffered greater changes. The main challenge of internationalization found, was to understand local culture and incorporate it into the company’s operations.

  10. Stolen beauty: gender, aesthetics and embodiment in Brazilian drama

    2008-01-01

    Full Text Available Drawing from a broader research on gender inflections in the Brazilian intellectual field and in Brazilian drama, between 1940 and 1968, the article discusses the relations between aesthetics and gender, and their implications on the careers of actresses Cacilda Becker, Maria Della Costa, Tônia Carrero and Cleyde Yáconis. According to testimony of those who saw her perform on stage, Cacilda was never hampered by her less favorable physical attributes. The hypothesis is that this is due to the cunning tricks of the conventions of dramatic arts that allow the dodging of social, gender and physical constraints. Widely evoked by the media to portrait, underline or diminish women under its focus, beauty rarely features as a relevant dimension in the analysis of female trajectories. Hence the interest in discussing the subject through its refraction on the process of social construction of artistic careers.

    Full Text Available This paper investigates changes in long-term operational and financial performance for a sample of Brazilian companies made initial public offerings (IPO's shares, in the period 2002-2008. This period showed a historically high number of IPOs, a heavily discontinued phenomenon with the international financial crisis of 2008. As performance measures were chosen six financial indicators usually adopted in the literature in periods of three years pre-IPO, year of listing and three years post-IPO. The indicators evaluated were size, growth rate, profitability, financial leverage, investment level and investment rate. The results show evidence that, on average, there were statistically significant improvements in size, profitability, investment level and investment rate. But there was no evidence statistically significant changes in the growth rate and financial leverage after the IPO of Brazilian firms.

  13. Beyond Brazilian Coalition Presidentialism: the Appropriation of the Legislative Agenda

    Directory of Open Access Journals (Sweden)

    Rafael Silveira e Silva

    2014-12-01

    Full Text Available Even though they possess several power resources, Brazilian Presidents also elaborate their legislative proposals based upon bills already being processed in Congress through a phenomenon called Appropriation of the legislative agenda. In this paper I examine the conditions under which this phenomenon occurs by means of a typology and a qualitative comparative analysis (QCA. I conclude that Appropriation provides the President with the expansion of the formal support base by controlling the agenda of allied and opposition parties as well as obtaining the "paternity" of several policies already in motion in Congress, thus enabling a public association of the President's actions and his or her party with the possibility of social benefits. Be it in the pursuit of promising agendas or for the maintenance of their own dominance, Appropriation shows that Brazilian Presidents must go beyond coalition presidentialism.

    Orthobunyaviruses are arboviruses in which at least 30 members are human pathogens. The members of group C orthobunyaviruses were first isolated in the Brazilian Amazon in 1950, since that time little information is accumulated about ecology and the medical impact of these virus groups in Brazil. Herein, we describe the evidence of Apeu virus (APEUV; an Orthobunyavirus member) infection in wild monkeys from the Brazilian Amazon forest. APEUV was detected by using a neutralizing antibody in serum and its RNA, suggesting past and acute infection of Amazonian monkeys by this virus. These results altogether represent an important contribution of orthobunyavirus ecology in the Amazon and an update about recent circulation and risk for humans with expansion of the cities to Amazon forest.

    2014-04-01

    Full Text Available Job stress can negatively affect the health of employees. As such, the investigation of its characteristics in different professional categories is relevant. The aim in this study was to analyze the predictive power of seven stressors (decision latitude, psychological demands at work, physical demands at work, social support from colleagues, ergonomic stressors, relationships with clients, job insecurity for job dissatisfaction, depression and psychosomatic problems in a sample of 702 Brazilian lawyers. The data were collected using a Brazilian version of the Job Content Questionnaire (JCQ. The results showed that decision latitude and social support were the main negative predictors of stress, while psychological demands and job insecurity were its main positive predictors. These results are discussed in the light of the demand-support-control model, which was used as a framework for the research.

  16. The Supply of Trade Credit by Brazilian Publicly Traded Firms

    Rafael Felipe Schiozer

    2011-12-01

    Full Text Available This paper investigates the determinants of trade credit supply by Brazilian publicly traded companies between the years of 2005 and 2008. International literature (both theoretical and empirical documents that the main determinants of trade credit supply are the size of the firm and the size of its debt. Both indicate that the availability of resources to the firm is an important factor for the supply of trade credit. In addition, the literature confirms strategic uses of trade credit such as those for price discrimination purposes. The results obtained using a sample of 157 Brazilian companies do not support that size and indebtedness are relevant determinants for trade credit supply, but they confirm the supply of trade credit as a strategic tool for the firms. Additionally we observed a significant decrease in trade credit supply in 2008, the year in which a severe international financial crisis took place.

    2010-06-01

    The very first law on animal experimentation has been approved recently in Brazil, and now is part of a set of the legal instruments that profile the Brazilian government's attitude toward the use of animals in experiments. Law 11794/08 establishes a new legal instrument that will guide new methods of conduct for ethics committees, researchers and representatives of animal protection societies. This comment aims to analyse critically the implications that this law brings to Brazilian reality. The link between it and the Russell and Burch's Three Rs concept is defined, and certain problems are identified. The conclusion is that the body of the law emphasises the refinement of animal experiments, but gives little importance to the principles of reduction and replacement.

    This study investigates the latest research on the profile of the Brazilian prison population, its demography and current laws and regulations. It aims in the direction of ensuring the human right to health. Brazilian prison system is a complex universe in which state and federal criminal contexts keep more than 607,000 people in custody. This population is composed of 75% of young and black people, 67% poorly educated and 41% are pre-trial detainees, living in overcrowded prisons and architecturally vandalized, with population growth of around 575% in 24 years, making this environment a major focus of production of diseases. The prison becomes the object of differentiated intervention by public bodies linked to the executive and the judiciary - it is worth remarking that the data show the high level of inequalities and health vulnerabilities among the prison population, whose needs involve a set of cross-sector of transverse public policies actions towards penal execution.

    Tacca, Fernando de

    2011-03-01

    The article explores contradictions and convergences between a medium (photography) and the image of the Brazilian Indian from the perspective of the history of Brazilian photography. During the first of three distinct moments, the image of the Indian was of someone exotic, in contradiction with the modern meaning of photography under the Second Empire. During the second moment, in the first fifty years of the twentieth century, the boundaries between ethnography and Brazil as a nation were blurred, as exemplified by the Rondon Commission/Indian Protection Bureau's Research Section (Serviço de Proteção ao Índio) and Brazil's modern photojournalism, as found in the magazine Cruzeiro. During the third moment, the expressions of an ethno-poetry present in the photographs of Cláudia Andujar can be seen to blend medium and image as an ethnographic space in contemporary art.

  20. Effects of interest and exchange rate policies on Brazilian exports

    Cláudia Maria Sonaglio

    2016-01-01

    Full Text Available In heterodox literature, the industrial sector is considered strategic for economic development. Consequently, reducing the contribution of this sector in the production of the country before it has reached the stage of economic maturity, affects the productive dynamics and slow technical progress. The appreciation of the real exchange rate is seen as one of the factors responsible for the reduction of the external competitiveness of Brazilian manufactures, and this exchange rate valuation may be occurring due to the differences between domestic and international interest rates. Given this context, the aim of this study is to evaluate the impact of changes in the monetary and exchange rate policy and in the composition of the total exports on the performance of the Brazilian economy using a structuralist model. The results reinforce the importance of the manufacturing sector to economic growth, especially in a competitive exchange rate environment.

    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.

  2. Interethnic diversity of NAT2 polymorphisms in Brazilian admixed populations

    2010-10-01

    Full Text Available Abstract Background N-acetyltransferase type 2 (Nat2 is a phase II drug- metabolizing enzyme that plays a key role in the bioactivation of aromatic and heterocyclic amines. Its relevance in drug metabolism and disease susceptibility remains a central theme for pharmacogenetic research, mainly because of its genetic variability among human populations. In fact, the evolutionary and ethnic-specific SNPs on the NAT2 gene remain a focus for the potential discoveries in personalized drug therapy and genetic markers of diseases. Despite the wide characterization of NAT2 SNPs frequency in established ethnic groups, little data are available for highly admixed populations. In this context, five common NAT2 SNPs (G191A, C481T, G590A, A803G and G857A were investigated in a highly admixed population comprised of Afro-Brazilians, Whites, and Amerindians in northeastern Brazil. Thus, we sought to determine whether the distribution of NAT2 polymorphism is different among these three ethnic groups. Results Overall, there were no statistically significant differences in the distribution of NAT2 polymorphism when Afro-Brazilian and White groups were compared. Even the allele frequency of 191A, relatively common in African descendents, was not different between the Afro-Brazilian and White groups. However, allele and genotype frequencies of G590A were significantly higher in the Amerindian group than either in the Afro-Brazilian or White groups. Interestingly, a haplotype block between G590A and A803G was verified exclusively among Amerindians. Conclusions Our results indicate that ethnic admixture might contribute to a particular pattern of genetic diversity in the NAT2 gene and also offer new insights for the investigation of possible new NAT2 gene-environment effects in admixed populations.

  3. 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 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.

    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 resumption of the Brazilian Nuclear Program (BNP), in the proposed size and after 20 years of paralysis, requires profound changes in the current organizational modeling of the national nuclear industry. The effectiveness of any process of organizational change is limited to three factors. The theoretical bottleneck happens when you do not know enough about a phenomenon in order to effect the desired changes. The resource bottleneck occurs when knowledge may be available to change people's behavior but the funds necessary for implementation may be lacking. The organizational bottleneck emerges when there are knowledge and resources to solve a problem, but may not able to organize the resources in order to carry out the problem-solving effort. In the case of resumption of BNP seems clear that there is the knowledge of what is needed to make policy and the intention to allocate the necessary resources. But the question is the following: the current organizational model of the Brazilian nuclear sector is consistent with the goals laid down in the scenario of resumption of BNP? That is, is there organizational ability to leverage a program of the size proposed for the nuclear area? Find answers to these questions is crucial, because the organizational model of the Brazilian nuclear sector consists of elements involving a complex interorganizational system. Thus, this article is to examine the appropriateness of the current organizational modeling of the Brazilian nuclear sector to current demands of society. As a result, the article aims to propose recommendations for a remodeling of the nuclear sector, taking into account the current national and international scenarios of nuclear energy. (author)

    The use of seven domains for the Oral Health Impact Profile (OHIP)-EDENT was not supported for its Brazilian version, making data interpretation in clinical settings difficult. Thus, the aim of this study was to assess patients' responses for the translated OHIP-EDENT in a group of edentulous subjects and to develop factor scales for application in future studies. Data from 103 conventional and implant-retained complete denture wearers (36 men, mean age of 69.1 +/- 10.3 years) were assessed using the Brazilian version of the OHIP-EDENT. Oral health-related quality of life domains were identified by factor analysis using principal component analysis as the extraction method, followed by varimax rotation. Factor analysis identified four factors that accounted for 63% of the 19 items total variance, named masticatory discomfort and disability (four items), psychological discomfort and disability (five items), social disability (five items) and oral pain and discomfort (five items). Four factors/domains of the Brazilian OHIP-EDENT version represent patient-important aspects of oral health-related quality of life.

Brazilian law have already contemplated burnout syndrome as a mental and behavioural disorder related to work. The aim of this study was to identify the prevalence of burnout in a sample of Brazilian teachers. Methods: The sample was composed of 714 teachers from 8 schools in Porto Alegre and its metropolitan area (Brazil. The levels of burnout were evaluated by the Spanish Burnout Inventory, educational version (SBI-Ed. In addition, Psychosomatic disorders were estimated by the UNIPSICO subscale. Results: The percentage of participants who indicated high levels of burnout was 12 % (Profile 1, and 5.6% fell into Profile 2 because they were affected by strong feelings of guilt. Moreover, participants with high scores on the SBI dimensions (low on Enthusiasm toward the job scored significantly higher on psychosomatic disorders than participants with low scores. Conclusions: Based on psychometric considerations, participants who fit Profile 2 of burnout could be considered burnout cases according to Brazilian legislation. However, using a clinical interview to make the diagnosis is recommended.

    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.

    In recent years successive Brazilian governments have actively pursued economic and social policies aimed at reducing poverty and promoting social equality and inclusion. In the field of energy, this has meant introducing and implementing programs aimed at expanding the supply of safe and reliable energy to the poorest sectors of Brazilian society, including those living in remote rural areas. This paper draws attention on the findings of extensive field research to evaluate the impact of rural electrification on energy poverty in the context of government policies aimed at promoting energy equity. The authors re-examine the concept of an energy poverty line, seeking to fine tune its application to Brazilian social and economic realities, and then apply an analytical framework (Lorenz Curve, Gap Poverty, Gap Quadratic, Gini Coefficient and Sen Index) to evaluate the effectiveness of recent efforts in Brazil to expand access to electricity. One of the main conclusions of this study is that is that rural electrification leads to a significant reduction of the energy poverty level and a consequent improvement in energy equity. (author)

    Borreliosis caused by Borrelia burgdorferi sensu lato is a cosmopolitan zoonosis studied worldwide; it is called Lyme disease in many countries of the Northern Hemisphere and Lyme-like or Baggio-Yoshinari Syndrome in Brazil. However, despite the increasing number of suspect cases, this disease is still neglected in Brazil by the medical and veterinary communities. Brazilian Lyme-like borreliosis likely involves capybaras as reservoirs and Amblyomma and Rhipicephalus ticks as vectors. Thus, domestic animals can serve as key carriers in pathogen dissemination. This zoonosis has been little studied in horses in Brazil. The first survey was performed in the state of Rio de Janeiro, and this Brazilian Borreliosis exhibits many differences from the disease widely described in the Northern Hemisphere. The etiological agent shows different morphological and genetic characteristics, the disease has a higher recurrence rate after treatment with antibiotics, and the pathogen stimulates intense symptoms such as a broader immune response in humans. Additionally, the Brazilian zoonosis is not transmitted by the Ixodes ricinus complex. With respect to clinical manifestations, Baggio-Yoshinari Syndrome has been reported to cause neurological, cardiac, ophthalmic, muscle, and joint alterations in humans. These symptoms can possibly occur in horses. Here, we present a current panel of studies involving the disease in humans and equines, particularly in Brazil.

    Full Text Available The Brazilian government has been promoting energy efficiency measures for industry since the eighties but with very limited returns, as shown in this paper. The governments of some other countries dedicated much more effort and funds for this area and reached excellent results. The institutional arrangements and types of programmes adopted in these countries are briefly evaluated in the paper and provide valuable insights for several proposals put forward here to make more effective the Brazilian government actions directed to overcome market barriers and improve energy efficiency in the local industry. The proposed measures include the creation of Industrial Assessment Centres and an executive agency charged with the coordination of all energy efficiency programmes run by the Federal government. A large share of the Brazilian industry energy consumption comes from energy-intensive industrial branches. According to a recent survey, most of them have substantial energy conservation potentials. To materialize a fair amount of them, voluntary targets concerning energy efficiency gains should start to be negotiated between the Government and associations representing these industrial branches. Credit facilities and tax exemptions for energy-efficient equipment’s should be provided to stimulate the interest of the entrepreneurs and the setting-up of bolder targets.

    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 Gleison V Duarte,1 Larissa Porto-Silva,2 Maria de Fátima Paim de Oliveira1 1Dermatology Department, Federal University of Bahia, Salvador, 2Escola Bahiana de Medicina e Saúde Pública, Salvador, BA, Brazil Abstract: 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 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.

    Full Text Available Since the recent discovery of Samba virus, the first representative of the family Mimiviridae from Brazil, prospecting for mimiviruses has been conducted in different environmental conditions in Brazil. Recently, we isolated using Acanthamoeba sp. three new mimiviruses, all of lineage A of amoebal mimiviruses: Kroon virus from urban lake water; Amazonia virus from the Brazilian Amazon river; and Oyster virus from farmed oysters. The aims of this work were to sequence and analyze the genome of these new Brazilian mimiviruses (mimi-BR and update the analysis of the Samba virus genome. The genomes of Samba virus, Amazonia virus and Oyster virus were 97%–99% similar, whereas Kroon virus had a low similarity (90%–91% with other mimi-BR. A total of 3877 proteins encoded by mimi-BR were grouped into 974 orthologous clusters. In addition, we identified three new ORFans in the Kroon virus genome. Additional work is needed to expand our knowledge of the diversity of mimiviruses from Brazil, including if and why among amoebal mimiviruses those of lineage A predominate in the Brazilian environment.

Specifically, were identified: a authors and their social networks of scientific production; b researched topics, models for accruals detection, authors’ networks and the period studied; c methodological procedures used. A bibliometric survey, with a quantitative approach was performed through the analysis of 17 Brazilian accounting journals, since their first edition until the year 2010. Out of them, 10 published articles having the theme earning management in the title, abstract or keywords. The 32 identified articles were submitted to content analysis and then the data were presented from the perspective of social networks. The survey results show that: the authors and their social networks of production originates mostly from Universidade de São Paulo (USP; the most researched theme was the methods or means to conduct earnings management, and accruals measurement models, with emphasis on Kang and Sivaramakrishnan Model; the descriptive research, based on document and quantitative approach were the most commonly used forms in the articles researched. It is noteworthy that structural gaps are the topics, such as compensation plans, political costs and earnings management in different contractual environments. The research results can contribute to academia to highlight some features of the earnings management theme and its researchers, in the field of publications in Brazilian accounting journals.

    The hematology of wild and captive animals is essential for obtaining details about species and represents a simple method of diagnosing disease and determining prognosis. Few studies have described the morphology of chelonian blood cells, which are more common in sea and freshwater turtle species. Thus, in order to further our understanding and recognition of different chelonian cells types, the present study aimed to describe blood cells from the two species of Brazilian tortoises, Chelonoidis carbonarius and C. denticulatus. Cytochemical analysis of tortoise blood tissue with Panótico®, made it possible to describe all the of the chelonian cell types (with the exception of thrombocytes): erythrocytes, agranular leukocytes (monocytes and lymphocytes), and granular leukocytes (eosinophils, heterophils, basophils, and azurophils). These data are of high importance for establishing hematological profiles of Brazilian tortoises and reptiles. Therefore, based on our results and on comparative analyses with data from the literature for other reptile species, we can conclude that the blood cells described for Brazilian tortoises are found in all species of reptiles that have been analyzed thus far, and may be characterized and used as a comparative parameter between different groups to evaluate the health status of these animals.

    Full Text Available Brazil is the world's largest producer of oranges and uses more than 70% of the harvested fruits in the production of juices. The amount of processed orange is growing about 10% per year, confirming the trend of the Brazilian citrus for juice production. This research aimed to investigate the Brazilian orange juice production chain from 2005 to 2009. Data from the amount of frozen juice produced and exported, international price of orange juice, and intermediate transactions were assessed in order to make possible selection of all interveners involved in the chain. The study using the Social Network Analysis (SNA showed that the densest relationships in the network are from exporters to importers and from orange growers to the orange processing industry. No difference was found in the values of the network geodesic distance or the clustering coefficients from 2005 to 2009. The degree of centrality increased steadily throughout the years indicating that the processing industry attempts to minimize the risks by centralizing the actions. A decrease in export of orange juice from 2007 (2.07 10(6 t to 2008 (2.05 10(6 t was found, probably due to the world's financial crisis with recovery in 2009. Since 2004, there has been an increase of nearly 10% per year in the market preference of concentrate juice (OFCJ when compared to the "not from concentrated" juice (NFC. Nowadays the NFC market represents nearly 50% of all Brazilian export which impacted in the logistic distribution and transportation issues.

    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.

    Full Text Available Objective: To systematize studies on the anthropometric nutritional status of Brazilian indigenous children in order to examine the ability to address the totality of biological, anthropological, and ecological aspects, as well as to characterize the main analytical results of the determinants of nutritional status of Brazilian indigenous children. Methods: MedLine and Lilacs were searched using the intersection of "South American Indians" and "nutritional status" descriptors (the search in MedLine also included the descriptor "Brazil". Results: Overall, 65 studies were identified, and 23 were considered relevant to this study. The systematization of these studies highlights the concentration of studies in the midwestern and northern regions of Brazil, as well as the lack of cultural, biochemical, and food consumption approaches. Regarding nutritional status, we found: 1 greater vulnerability of younger children, especially in relation to stunting; 2 absence of differences in nutritional status according to sex; 3 socioeconomic determination of nutritional status; 4 differences in nutritional status between children from different villages. Conclusion: The nutritional status of Brazilian indigenous children is associated with age, socioeconomic status, and ethnic characteristics. Efforts are needed to understand the ethnic and cultural influence on nutritional status and on its causal network, as well as of various factors minimally discussed.

    The electronic ballot box has played a significant role in the consolidation of Brazilian political process. It has enabled paper ballots extinction as a support for the elector's vote as well as for voting counting processes. It is also widely known that election automation has decisively collaborated to the legitimization of Brazilian democracy, getting rid of doubts about the winning candidates. In 1995, when the project was conceived, it represented a compromise solution, balancing technical efficiency and costs trade-offs. However, this architecture currently limits the ergonomic enhancements to the device operation, transportation, maintenance and storage. Nowadays are available in the market devices of reduced dimensions, based on novel computational architecture, namely tablet computers, which emphasizes usability, autonomy, portability, security and low power consumption. Therefore, the proposal under discussion is the replacement of the current electronic ballot boxes for tablet-based devices to improve the ergonomics aspects of the Brazilian voting process. These devices offer a plethora of integrated features (e.g., capacitive touchscreen, speakers, microphone) that enable highly usable and simple user interfaces, in addition to enhancing the voting process security mechanisms. Finally, their operational systems features allow for the development of highly secure applications, suitable to the requirements of a voting process.

Our objectives herein are to understand which external country characteristics lead to international franchising operations and to ascertain the influence of such characteristics in the commitment of franchise chains in each country they operate in. The database has 54 Brazilian franchise chains with international operations in 26 countries, which implies in 157 franchises operating abroad. Regarding external environment factors, the independent variables form a group divided into market opportunity and business efficiency – trust and ease to doing business. The result of the three distinct clusters show how the market opportunity and the business efficiency (trust and ease in doing business work as drivers to the international operation of Brazilian franchises. The paper shows that the franchise chains operating in the USA (cluster 3 have an inferior international commitment in comparison with the franchises which operate in developed countries and in small Latin American countries (cluster 2. It is also possible to notice a large number of franchises that operate in underdeveloped countries from Latin America and Africa (cluster 1 with worse business efficiency due to the advantage of learning how to operate in a country that could have some similarities with Brazil

    Carolina Santos Mello

    Full Text Available Abstract Objective To assess the feeding profile of Brazilian infants and preschool children aged 6 months to 6 years, based on the qualitative and quantitative analysis of food and nutrient intake. Data source This review analyzed studies carried out in Brazil that had food survey data on infants and preschool children. The search was limited to publications from the last 10 years included in the LILACS and MEDLINE electronic databases. Data summary The initial search identified 1480 articles, of which 1411 were excluded after the analysis of abstracts, as they were repeated or did not meet the inclusion criteria. Of the 69 articles assessed in full, 31 articles contained data on food survey and were selected. Only three studies concurrently assessed children from different Brazilian geographical regions. Of the assessed articles, eight had qualitative data, with descriptive analysis of food consumption frequency, and 23 had predominantly quantitative data, with information on energy and nutrient consumption. Conclusions The articles assessed in this review showed very heterogeneous results, making it difficult to compare findings. Overall, the feeding of infants and preschool children is characterized by low consumption of meat, fruits, and vegetables; high consumption of cow's milk and inadequate preparation of bottles; as well as early and high intake of fried foods, candies/sweets, soft drinks, and salt. These results provide aid for the development of strategies that aim to achieve better quality feeding of Brazilian infants and preschoolers.

    The Brazilian National Institute for Space Research (INPE) has been monitoring the Brazilian Legal Amazon deforestation through the PRODES project since 1988, providing yearly deforestation maps based on about 60 m spatial resolution. Additionally, INPE's Real Time Deforestation Detection System (DETER) has monthly indicating, based on high temporal resolution satellite data, where and when the forest is being felled. However, those monitoring processes are mainly based on visual interpretation, which is accurate but a hard and time consuming task. The Spectral-Temporal Analysis by Response Surface (STARS), which synthesizes the full information content of a multitemporal-multispectral remote sensing image dataset to represent the spectral variation over time of features on the Earth's surface, comes as an alternative for applications in land cover change detection, such as deforestation in the Brazilian Amazon. Thus, since deforestation process presents particular spectral changes over time, spectral-temporal response surfaces could be fitted to describe its change patterns, allowing to detect deforested areas. In this context, this work aims to apply the STARS to detect deforestation in the Brazilian Amazon, using Landsat-5 multitemporal-multispectral images. Four georeferenced images covering about 3.400 square kilometres within the Mato Grosso State, Brazil (13°17'S; 55°50'W to 14°20'S; 55°10'W) were used: one Multispectral Scanner (MSS) image from 1980 (bands 4, 5, 6 and 7 - 60 m spatial resolution); and three Thematic Mapper (TM) images from 1990, 2000 and 2010 (bands 1, 2, 3, 4, 5 and 7 - 30 m spatial resolution). The MSS image was resampled to 30 m to match the TM spatial resolution. All images were then used as input for STARS resulting in a Multi-Coefficient Image (MCI) with 10 synthetic bands formed by the 10 fitted coefficients of a Polynomial Trend Surface (PTS) model with degree equal to three. The MCI was used as input for a decision tree (DT

    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.

    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.

    Full Text Available Due to the necessity of establishing animal welfare standards for the Brazilian dairy sector in harmony to the new consumer’s requirements and legislation, it was drawn up the project Welfare Quality (WQ - Brazil, based on the proposed project Welfare Quality ® European Union for dairy cattle. The assessments of animal welfare were performed in seven dairy farms at São Paulo/Brazil. They were selected in order to represent the main types of dairy farms found in Brazil. To carry out the project, it was used the evaluation protocol of welfare in Dairy Cattle Welfare Quality ® Assessment Protocol for Cattle, which is based on the principles of Good Feeding, Proper Installation, Good Health and Appropriate Behavior. The protocol defines four possible categories for the assessed dairy farms: Not classified, Acceptable, Enhanced or Excellent. Only one farm received category “Acceptable”, while the others received category “Enhanced”. A highlight is the unsatisfactory score for the principle “Appropriate Behavior” received by four farms. Possible reasons are inappropriate animals handling, assessor subjectivity and/or protocol’s subjectivity. To this final point, some emotion standards are vague and do not describe how animals should behave for each type of situation during evaluation. Finally, it can be concluded that the European protocol for the Evaluation of Welfare in Dairy Cattle Welfare Quality ® may be used in Brazilian dairy farms provided there is previous assessor training and adaptation of some points to be feasible to Brazilian dairy sector.

    Full Text Available The transparency of governments to their citizens is seen as a necessary factor in democratic accountability and, consequently, in the consolidation of democracy. Although the importance of transparency in government is often highlighted, its causes are still unknown, especially in the Brazilian context. Following the trend of international empirical research, this exploratory study investigates the relationships between three sets of variables (current and past fiscal variables, socioeconomic variables and political variables and fiscal transparency in the Brazilian subnational context. To identify the relationship between fiscal, socioeconomic and political variables and fiscal transparency, the multiple linear regression technique was used. Prior to conducting the regression using the method of ordinary least squares, factor analysis was used, aiming to group the fiscal and socioeconomic variables into factors not only to reduce their quantity but also to eliminate their multicollinearity problems. Political variables, due to their qualitative nature, remained in their original form. The factor analysis sorted the variables into two groups: fiscal and socioeconomic factors. Because multiple regression allows only for the evaluation of the relationship between the parties included in the sample and the reference party, an F test was used to assess differences in the level of transparency among political parties. The results indicated that fiscal and socioeconomic variables explain the transparency levels of the Brazilian States. However, the political variables were not significant, indicating that the disclosure of fiscal information in Brazil seems not to be influenced by political ideologies. Furthermore, it is evident that the lack of a regulatory model of transparency in the budget process leads States to disclose a great deal of information about budget execution. Finally, the findings indicate that as an instrument for democratic

  20. Priority Areas for Establishing National Forests in the Brazilian Amazon

    2002-06-01

    Full Text Available Brazil will benefit if it gains control of its vast Amazonian timber resources. Without immediate planning, the fate of much of the Amazon will be decided by predatory and largely unregulated timber interests. Logging in the Amazon is a transient process of natural resource mining. Older logging frontiers are being exhausted of timber resources and will face severe wood shortages within 5 yr. The Brazilian government can avoid the continued repetition of this process in frontier areas by establishing a network of National Forests (Florestas Nacionais or Flonas to stabilize the timber industry and simultaneously protect large tracts of forest. Flonas currently comprise less than 2% of the Brazilian Amazon (83,000 km2. If all these forests were used for sustainable logging, they would provide less than 10% of the demand for Amazonian timber. To sustainably supply the present and near-future demand for timber, approximately 700,000 km2 of the Amazon forest needs to be brought into well-managed production. Brazil's National Forest Program, launched in 2000, is designed to create at least 400,000 km2 of new Flonas. Objective decision-making tools are needed to site these new national forests. We present here a method for optimally locating the needed Flonas that incorporates information on existing protected areas, current vegetation cover, areas of human occupation, and timber stocks. The method combines these data in a spatial database that makes it possible to model the economic potential of the region's various forests as a function of their accessibility and timber values while constraining model solutions for existing areas of protection or human occupation. Our results indicate that 1.15 x 106 km2 of forests (23% of the Brazilian Amazon could be established as Flonas in a manner that will promote sustainable forest management; these Flonas would also serve as buffer zones for fully protected areas such as parks and reserves.

  1. Smoke impacts from agricultural burning in a rural Brazilian town.

    2001-03-01

    Agricultural and silvicultural biomass burning is practiced in many undeveloped portions of the Amazon basin. In Rond nia, Brazil, such burning is restricted to a brief period in the dry season of August and September to minimize the duration of air quality impacts and to attempt to control escaped fires. During this period, much of the region and the communities within it experience significant exposure to smoke from agricultural and forest fires. In cooperation with Brazilian scientists of the University of Brasilia, the Brazilian Organization for Agricultural Research (EMBRAPA), and the Alternative to Slash and Burn Program coordinated by the International Center for Research in Agroforestry (ICRAF), ambient air quality was measured in Theobroma, a small town in Rond nia, during one week of the open burning period of 1995 to supplement available air quality data and to foster public awareness of the impacts of widespread fires. Personal sampling equipment was used to measure ambient levels of formaldehyde (HCHO), acrolein, CO, benzene, and respirable PM in outdoor air. The data obtained were compared with established Brazilian and U.S. ambient air quality guidelines. Ambient levels of respirable PM averaged 191 microg/m3, HCHO averaged 12.8 ppb, CO averaged 4.2 ppm, and benzene averaged 3.2 ppb. Almost all acrolein samples were less than the detection limit of 1 ppb. The results showed that the public can be exposed to relatively high levels of pollutants under the prescribed burning smoke management strategy of a two- to three-week prescription burning period, although this is an improvement over past years when burning was unregulated and continued through most of the dry season. The results also demonstrate the feasibility of using personal exposure monitoring equipment for low-cost surveys of ambient air quality in polluted regions.

    Precambrian rocks comprise nearly one-quarter of the surface of Brazil and range from Paleoarchean (ca. 3.6 Ga) to the latest Ediacaran (0.542 Ga) in age. Except for controversial phosphatized `embryo-like' microfossils like those from the lower Ediacaran Doushantuo Formation, China and complex rangeomorphs, Brazilian research has revealed all major categories of Precambrian life forms described elsewhere - microbialites, biomarkers, silicified microfossils, palynomorphs, vase-shaped microfossils, macroalgae, metazoans, vendobionts and ichnofossils - but the paleobiological significance of this record has been little explored. At least four occurrences of these fossils offer promise for increased understanding of the following aspects of Precambrian biospheric evolution: (i) the relationship of microbialites in 2.1-2.4 Ga old carbonates of the Minas Supergroup in the Quadrilátero Ferrífero, Minas Gerais (the oldest Brazilian fossils) to the development of the early oxygenic atmosphere and penecontemporaneous global tectonic and climatic events; (ii) the evolutionary and biostratigraphic significance of Mesoproterozoic to Ediacaran organic-walled microfossils in central-western Brazil; (iii) diversity and paleoecological significance of vase-shaped heterotrophic protistan microfossils in the Urucum Formation (Jacadigo Group) and possibly the Bocaina Formation (Corumbá Group), of Mato Grosso do Sul; and (iv) insights into the record of skeletogenesis and paleoecology of latest Ediacaran metazoans as represented by the abundant organic carapaces of Corumbella and calcareous shells of the index fossil Cloudina, of the Corumbá Group, Mato Grosso do Sul. Analysis of the Brazilian Precambrian fossil record thus holds great potential for augmenting paleobiological knowledge of this crucial period on Earth and for developing more robust hypotheses regarding possible origins and evolutionary pathways of biospheres on other planets.

    Full Text Available This paper presents an overview of the activities developed by the Structural Integrity Group at the Institute of Aeronautics and Space - IAE, Brazil, as well as the status of ongoing work related to the life extension program for aircraft operated by the Brazilian Air Force BAF. The first BAF-operated airplane to undergo a DTA-based life extension was the F-5 fighter, in the mid 1990s. From 1998 to 2001, BAF worked on a life extension project for the BAF AT- 26 Xavante trainer. All analysis and tests were performed at IAE. The fatigue critical locations (FCLs were presumed based upon structural design and maintenance data and also from exchange of technical information with other users of the airplane around the world. Following that work, BAF started in 2002 the extension of the operational life of the BAF T-25 “Universal”. The T-25 is the basic training airplane used by AFA - The Brazilian Air Force Academy. This airplane was also designed under the “safe-life” concept. As the T-25 fleet approached its service life limit, the Brazilian Air Force was questioning whether it could be kept in flight safely. The answer came through an extensive Damage Tolerance Analysis (DTA program, briefly described in this paper. The current work on aircraft structural integrity is being performed for the BAF F-5 E/F that underwent an avionics and weapons system upgrade. Along with the increase in weight, new configurations and mission profiles were established. Again, a DTA program was proposed to be carried out in order to establish the reliability of the upgraded F-5 fleet. As a result of all the work described, the BAF has not reported any accident due to structural failure on aircraft submitted to Damage Tolerance Analysis.

    Full Text Available This paper investigates the sources of structural change in the Brazilian economy in the 2000s. On that purpose, it uses the input-output structural decomposition analysis and introduces a method to correct the influence of prices on the time behavior of the technical coefficients, making them actually represent changes in the production structure. Results show that most of the growth differential between services and industry in that period was induced by the production structure: more precisely, by a lower intermediate consumption of domestic industrial inputs by the production chain of all economic sectors, concomitant with a higher intermediate consumption of services.

    Full Text Available This study seeks to understand the competitive pattern and strategy of the firms in the Brazilian automobile financing market. First, we analyzed the strong segmentation observed in this market, determining market niches. We then estimated reaction functions to price changes. The results indicated that the three largest companies in the sector have a strong influence on interest rate setting within the entire segment. This phenomenon characterizes the competition of this sector as the leader-follower type, rather than Bertrand competition, the latter of which is often expected in the banking sector and it demonstrates the existence of the leading firms' market power.

    This study aimed to examine methodological issues in the theses and dissertations that used social representations theory (SRT) in Brazilian nursing. Twenty-two dissertations and 44 theses were considered. Categorical content analysis was applied, based on five aspects: objects studied, place of SRT, the number of study participants, data collection techniques and data analysis. The predominance of case studies and use, especially of semi-structured interviews, although relevant to the study of SR, do not sufficiently consider the extent of suck knowledge sharing in society. One must take into account lay knowledge to understand health care contextualized studies on health care.

    Full Text Available A simulation model based on satellite observations of monthly vegetation greenness from the Moderate Resolution Imaging Spectroradiometer (MODIS was used to estimate monthly carbon fluxes in terrestrial ecosystems of Brazilian Amazon and Cerrado regions over the period 2000–2002. The NASA-CASA (Carnegie Ames Stanford Approach model estimates of annual forest production were used for the first time as the basis to generate a prediction for the standing pool of carbon in above-ground biomass (AGB; g C m−2 for forested areas of the Brazilian Amazon region. Plot-level measurements of the residence time of carbon in wood in Amazon forest from Malhi et al. (2006 were interpolated by inverse distance weighting algorithms and used with CASA to generate a new regional map of AGB. Data from the Brazilian PRODES (Estimativa do Desflorestamento da Amazônia project were used to map deforested areas. Results show that net primary production (NPP sinks for carbon varied between 4.25 Pg C yr−1 (1 Pg=1015 g and 4.34 Pg C for the region and were highest across the eastern and northern Amazon areas, whereas deforestation sources of CO2 flux from decomposition of residual woody debris were higher and less seasonal in the central Amazon than in the eastern and southern areas. Increased woody debris from past deforestation events was predicted to alter the net ecosystem carbon balance of the Amazon region to generate annual CO2 source fluxes at least two times higher than previously predicted by CASA modeling studies. Variations in climate, land cover, and forest burning were predicted to release carbon at rates of 0.5 to 1 Pg C yr−1 from the Brazilian Amazon. When direct deforestation emissions of CO2 from forest burning of between 0.2 and 0.6 Pg C yr−1 in the Legal Amazon are overlooked in regional budgets, the year-to-year variations in this net biome flux may

    Lucio’s phenomenon is an uncommon reaction characterized by severe necrotizing cutaneous lesions that occurs in patients with Lucio’s leprosy and lepromatous leprosy. It is considered by some authors as a variant of type 2 or 3 reaction. Death can occur because of blood dyscrasia or sepsis. Precipitating factors include infections, drugs and pregnancy. We report a 31-year-old female patient exhibiting both clinical and histopathological features of lepromatous leprosy and Lucio’s phenomenon presenting favorable response to treatment. We complement our report with a literature review of the Brazilian cases of Lucio’s phenomenon published in Portuguese and English.

    The leaves of jaborandi are commercially exploited in the Brazilian Northeast for industrial extraction of pilocarpine, an alkaloid with potent cholinergic activity. The leaves also contain an essential oil whose composition is registered in the literature in a confusing and incomplete way. Chemical re-examination of the essential oil from five distinct Pilocarpus species was conducted together with an analysis of the leaves used by local industry. It was found to contain terpenes, sesquiterpenes and ketones. Some of them are reported for the first time in the genus.

    This paper proposes a new way to model and analyze contagion in interbank networks. We use a unique dataset from the Brazilian financial system and include all active financial intermediaries. We show that the contagion chain has a short propagation path. We find that first-round contagion is generated only by banks and that medium-sized banks can generate contagion, which implies that size is not the sole determinant of importance within networks. Most vulnerable financial institutions are not banks. Finally, we compute a lower bound for the financial system expected losses in a 1-year horizon. The results contribute to the development of a financial stability-monitoring toolkit.

    This article aims to reconstruct the history of the term "racial democracy" in Brazilian sociological literature. This term, usually associated with the idea of "myth", is used in many studies of race relations without little definition or clarity. This article retraces its origins, in particular by showing that the concept is not the invention of Gilberto Freyre. It then examines the evolution of its use with particular emphasis on Unesco's research in the 1950s and the texts of Florestan Fernandes in the 1960s.

    ABSTRACT OBJECTIVE To estimate the prevalence of arterial hypertension and obesity and the population attributable fraction of hypertension that is due to obesity in Brazilian adolescents. METHODS Data from participants in the Brazilian Study of Cardiovascular Risks in Adolescents (ERICA), which was the first national school-based, cross-section study performed in Brazil were evaluated. The sample was divided into 32 geographical strata and clusters from 32 schools and classes, with regional and national representation. Obesity was classified using the body mass index according to age and sex. Arterial hypertension was defined when the average systolic or diastolic blood pressure was greater than or equal to the 95th percentile of the reference curve. Prevalences and 95% confidence intervals (95%CI) of arterial hypertension and obesity, both on a national basis and in the macro-regions of Brazil, were estimated by sex and age group, as were the fractions of hypertension attributable to obesity in the population. RESULTS We evaluated 73,399 students, 55.4% female, with an average age of 14.7 years (SD = 1.6). The prevalence of hypertension was 9.6% (95%CI 9.0-10.3); with the lowest being in the North, 8.4% (95%CI 7.7-9.2) and Northeast regions, 8.4% (95%CI 7.6-9.2), and the highest being in the South, 12.5% (95%CI 11.0-14.2). The prevalence of obesity was 8.4% (95%CI 7.9-8.9), which was lower in the North region and higher in the South region. The prevalences of arterial hypertension and obesity were higher in males. Obese adolescents presented a higher prevalence of hypertension, 28.4% (95%CI 25.5-31.2), than overweight adolescents, 15.4% (95%CI 17.0-13.8), or eutrophic adolescents, 6.3% (95%CI 5.6-7.0). The fraction of hypertension attributable to obesity was 17.8%. CONCLUSIONS ERICA was the first nationally representative Brazilian study providing prevalence estimates of hypertension in adolescents. Regional and sex differences were observed.

    Full Text Available Quality in servicing customers is important for the industry. Nonetheless, problems in defining such constructs as service quality and customer satisfaction, along with difficulties in putting into operation current instruments to measure them, constitute constraints for practice and research. This paper presents a framework aimed at addressing the quality of banking services, framework which is based on customer perceptions surveyed by a consultant firm with 11,936 customers of a Brazilian bank. From the survey and the theoretical developments, five constructs driving the quality of banking services and customer satisfaction emerged: (1 relationship with the customer, (2 business and financial transactions, (3 information technology, (4 branch, and (5 image.

    This study evaluated the economic impact of health events associated with air pollution in Brazilian metropolitan regions. From the estimated mortality attributable to concentrations of particulate matter (PM) in 29 metropolitan areas, with a total of 20,050 deaths, the costs associated with mortality were calculated by means of the use of DALY (Disability Adjusted Life Years) methodology. The cost of premature deaths in Brazil resulted in $ 1.7 billion annually. Translating losses in public health to economic values served to compare this data with the expense budget of the Ministry of Health and highlight priorities in decision-making of public policies that minimize the magnitude of these impacts.

    Understanding the impact of road investments on deforestation is part of a complete evaluation of the expansion of infrastructure for development. We find evidence of spatial spillovers from roads in the Brazilian Amazon: deforestation rises in the census tracts that lack roads but are in the same county as and within 100 km of a tract with a new paved or unpaved road. At greater distances from the new roads the evidence is mixed, including negative coefficients of inconsistent significance between 100 and 300 km, and if anything, higher neighbor deforestation at distances over 300 km.

    Full Text Available Many studies have been conducted in corporate finance regarding long-term investment and financing decisions. However, short-term asset investments play a significant role in the balance sheet of companies. Moreover, financial managers dedicate significantamounts of time and effort to the subject of working capital management, balancing current assets and liabilities. This paper provides insights regarding the key factors of working capital management by exploring the internal variables of a number of companies. This study used data from 2,976 Brazilian public companies from 2001 to 2008, and found that debt level, size and growth rate can affect the working capital management of companies.

    Full Text Available This paper deals with environmental issues from the perspective of Supply Chain Management. With the incorporation of environmental concerns in a systematic manner the concept of Green Supply Chain Management (GSCM has emerged. The subject GSCM interests not only to academics but also to professional audience especially with regard to new legal obligations, and social pressures of various types of stakeholders, as well as issues related to the competitiveness of enterprises and their supply chains. However, the way in which this knowledge is being produced in Brazil is not clear, hence the need for a mapping which areas and sub-areas of GSCM has been studied most frequently. Thus, this work can be characterized as a desk research that aims to analyze the Brazilian academic publications on green supply chain management. In order to delimit the scope of the research, we collected articles published from 2006 to 2010 in specific Brazilian congresses of Management and Production Engineering, as EnANPAD, SIMPOI and SIMPEP. 110 papers were collected and analyzed.The area of Green Operations represents 81% of published articles and 45% of these focus on Reverse Logistics. 70% of total papers are empirical and 77% use a qualitative approach, while 57% of the total are case studies

Participants were 730 subjects (65% women, aged from 17 to 70 years old (M = 31.0 years; SD = 11.43, from 21 Brazilian states. The sample was randomly split in two halves to cross-validate the results. With the first half of the sample (n1 = 365, an exploratory factor analysis (EFA was conducted. With the second half of the sample (n2 = 365, a confirmatory factor analysis (CFA assessed the fit of the exploratory model. Convergent validity and group differences were also evaluated. The EFA and CFA presented a one-dimensional structure for the P-Scale. Moderate correlations were found between the P-Scale and mental-health, subjective happiness and life-satisfaction. The levels of positivity presented a low positive correlation with age, educational level and financial income. Slightly significant effects were found for occupational status and marital status. Positivity appears to be more closely related to personal dispositions than to sociodemographic aspects. Our results suggest that the P-Scale is a reliable measure with which to evaluate the levels of positivity in Brazil.

    2014-09-01

    This study contributes to the health governance discussion by presenting a new data set that allows for comparisons of the management of health resources among Brazilian municipalities. Research on Brazil is particularly important as the provision of health services was decentralized in 1988 and since then municipalities have been given greater responsibilities for the management of fiscal resources for public health service provision. Based on detailed information on corruption practices (such as over-invoicing, illegal procurement and fake receipts) from audit reports of health programmes in 980 randomly selected Brazilian municipalities, this study deepens understanding of the relationship between health governance institutions and the incidence of corruption at the local level by exploring the extent to which horizontal and vertical accountabilities contribute to reducing the propensity of municipal government officials to divert public health resources for private gain. The results of our multiple regression analysis suggest that the experience of health municipal councils is correlated with reductions in the incidence of corruption in public health programmes. This impact is significant over time, with each additional year of health council experience reducing corruption incidence levels by 2.1% from baseline values. The findings reported in this study do not rely on the subjectivity of corruption measures which usually conflate the actual incidence of corruption with its perception by informants. Based on our results, we provide recommendations that can assist policy makers to reduce corruption.

    As with any other bioenergy product, bioethanol production requires fossil fuel inputs; hence the alleged benefits of energy security and carbon mitigation depend on the extent to which these inputs are capable of drawing a substantive bioenergetic yield. Brazilian ethanol, made out of sugarcane, has been reported as the most efficient gasoline substitute that is commercially available nowadays. For that reason it has been the object of several analyses on the energetics, i.e. energy balances. These studies surprisingly vary widely according with the scholar approach and are not fully comparable among them due to divergences in the assessment method. This paper standardises results of the four most prominent authors in the field, establishing a point of comparison and drawing some light on the energetics studies on biofuels. The main result is shown in , which homogenises the outcomes for referred studies in terms of unit of assessment in the energy input analysis. Subsequently, this information is also charted () explaining the source of divergence among authors. This work ends with a short reference and comparison to some energy balance studies carried out on feedstocks of diverse nature, highlighting the potential that sugarcane-based bioethanol represents nowadays. - Highlights: > Distribution stage could reduce energy ratio but its contribution is not significant. > In Pimentel and Patzek there is an evident impact of the industrial stage. > A coincidence across the studies was the major impact of the agricultural stage. > Brazilian technology to produce ethanol was proved the most energy efficient one.

    2011-01-01

    Propolis is a bee product, composed mainly of plant resins and beeswax, therefore its chemical composition varies due to the geographic and plant origins of these resins, as well as the species of bee. Brazil is an important supplier of propolis on the world market and, although green colored propolis from the southeast is the most known and studied, several other types of propolis from Apis mellifera and native stingless bees (also called cerumen) can be found. Propolis is usually consumed as an extract, so the type of solvent and extractive procedures employed further affect its composition. Methods used for the extraction; analysis the percentage of resins, wax and insoluble material in crude propolis; determination of phenolic, flavonoid, amino acid and heavy metal contents are reviewed herein. Different chromatographic methods applied to the separation, identification and quantification of Brazilian propolis components and their relative strengths are discussed; as well as direct insertion mass spectrometry fingerprinting. Propolis has been used as a popular remedy for several centuries for a wide array of ailments. Its antimicrobial properties, present in propolis from different origins, have been extensively studied. But, more recently, anti-parasitic, anti-viral/immune stimulating, healing, anti-tumor, anti-inflammatory, antioxidant and analgesic activities of diverse types of Brazilian propolis have been evaluated. The most common methods employed and overviews of their relative results are presented. PMID:21631940

    This paper presents a new date for one of the oldest shellmounds of the central-south Brazilian coast. This date seems to confirm three previous results obtained from two other shellmounds in the same region and formerly seen as unreliable by the archaeological community. A charcoal sample from a coastal shellmound located in the state of Rio de Janeiro, Sambaqui do Algodao, was dated by {sup 14}C-AMS to 7860 {+-} 80 years BP. Besides confirming the previous ones, this new date is pulling back by some two thousand years the consensually accepted antiquity for the initial settlement of the central-south Brazilian coast - around 6000 years BP. The geographical and chronological proximity of those archaeological sites suggest that the initial settlement of the coast would have begun in this region rather than in the nuclear area with denser concentrations of shellmounds further to the South. It also strengthens the evidence of the possible route used by inland hunter-gatherers to reach this part of the coast.

    Full Text Available Football as a business is a chance of socio economic leverage. Football organizations need to become modern since the Brazilian society is unhappy with the quality of service provide and clubs, mostly emerged on debts, end up devaluating their brands associated with an inefficient administration. In 1998, a new factor came to influence this scenario: it was sanctioned the Law no. 9.615, know as “Lei Pelé”, which extinguished the pass of football players. Before that, football clubs have as their major income source the transfer of players. After this regulatory change, clubs were obligated to develop alternative sources of income. The current article intends to analyze this new scenario and to propose options to the clubs not only related to the players transfer market. To do that, it will be shown a comparative study between the Brazilian football and the European Football, identifying the strategies and the results. In this context, public support and the relation between clubs and their clients appeared as the major items.

    Malocclusions are generally treated in adolescents and adults, but they are established at an early age. The purpose of this study was to determine the prevalence of malocclusions in a young Brazilian population. The sample included 926 children, 8 to 12 years old, attending 5 public schools in the state of Goias, Brazil The type of occlusion was visually determined during the oral exam and statistical analysis, Chi-square test, was performed to correlate the prevalence of malocclusion with gender and with age. 819 patients out of the 926 patients had some type of malocclusion. From those, 513 patients had a class I malocclusion, 201 patients were classified as class II malocclusion, and 105 patients were class III malocclusion. Vertically, 62 patients showed a deep bite and 61 patients had an open bite. Transversely, 40 patients presented a bilateral posterior crossbite, 54 patients had a posterior crossbite on the left side, and 39 patients had a posterior crossbite on the right side. No significant correlation between gender and malocclusions was found and the number of patients with malocclusions between boys and girls were similar. Considering the three spatial planes, there is a high prevalence of malocclusions among the young Brazilian population. Therefore, the dental community must improve health policies and treat malocclusions earlier.

    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.

    Full Text Available This study was conducted in order to understand how Brazilian cultural traits are manifested in the relations of trade between employees of micro and small retailers and their customers. How, in marketing, one of the theoretical perspectives that seek to account for the relationship between businesses and consumers is relationship marketing, we sought to understand the exchanges and also to support this view. Assuming that the exchange ratio is also a commercial and social human relationship, we tried to treat the exchange as a social phenomenon. The research, qualitative in nature, was conducted in five retailers in a small city in southern Minas Gerais during the period of one year (Dec/2008 to Dec/2009 using ethnography as a method. As to results, as evidenced personalism, the warmth, the valuation of non-manual work, aversion to conflict, and the cunning knack manifested in trade relations. The main conclusion reached is that the reality of retail trade is complex and multifaceted as much as is the Brazilian culture.

    Full Text Available The text presents the partial conclusions of the research in which a comparative analysis was made of narratives that address the issue of Brazilian Military Dictatorship (1964-1985 within the set of History textbooks of Elementary School approved by the Brazilian National Textbook Program (Programa Nacional do Livro Didático - PNLD/2011. 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.

    OBJECTIVE: Changes in the neonatal gut environment allow for the colonization of the mucin layer and lumen by anaerobic bacteria. The aim of the present study was to evaluate Bifidobacterium, Lactobacillus and Lactococcus colonization through the first year of life in a group of 12 Brazilian infants and to correlate these data with the levels of Escherichia coli. The presence of anaerobic members of the adult intestinal microbiota, including Eubacterium limosum and Faecalibacterium prausnitzii, was also evaluated. METHODS: Fecal samples were collected during the first year of life, and 16S rRNA from anaerobic and facultative bacteria was detected by real-time PCR. RESULTS: Bifidobacterium was present at the highest levels at all of the studied time points, followed by E. coli and Lactobacillus. E. limosum was rarely detected, and F. prausnitzii was detected only in the samples from the latest time points. CONCLUSION: These results are consistent with reports throughout the world on the community structure of the intestinal microbiota in infants fed a milk diet. Our findings also provide evidence for the influence of the environment on intestinal colonization due to the high abundance of E. coli. The presence of important anaerobic genera was observed in Brazilian infants living at a low socioeconomic level, a result that has already been well established for infants living in developed countries.

    Full Text Available Abstract Propolis is a bee product, composed mainly of plant resins and beeswax, therefore its chemical composition varies due to the geographic and plant origins of these resins, as well as the species of bee. Brazil is an important supplier of propolis on the world market and, although green colored propolis from the southeast is the most known and studied, several other types of propolis from Apis mellifera and native stingless bees (also called cerumen can be found. Propolis is usually consumed as an extract, so the type of solvent and extractive procedures employed further affect its composition. Methods used for the extraction; analysis the percentage of resins, wax and insoluble material in crude propolis; determination of phenolic, flavonoid, amino acid and heavy metal contents are reviewed herein. Different chromatographic methods applied to the separation, identification and quantification of Brazilian propolis components and their relative strengths are discussed; as well as direct insertion mass spectrometry fingerprinting. Propolis has been used as a popular remedy for several centuries for a wide array of ailments. Its antimicrobial properties, present in propolis from different origins, have been extensively studied. But, more recently, anti-parasitic, anti-viral/immune stimulating, healing, anti-tumor, anti-inflammatory, antioxidant and analgesic activities of diverse types of Brazilian propolis have been evaluated. The most common methods employed and overviews of their relative results are presented.

    Full Text Available A framing analysis of mainstream on-line organizations and their bloggers and columnists on the 2010 Brazilian Presidential Elections revealed that framing do have the potential to expose ideological elements on how the media position themselves in the public sphere.Thematic and episodic frames dominated the news with a special focus on press freedom, social and economic problems, corruption and abortion. The main-stream media focused their coverage on the Workers’ Party employing primarily a critical/ adversarial tone as opposed to an interpretive analysis tone. Professional ideology mixed with political preferences both by journalists and mediaowners marked the Brazilian online coverage blurring the lines between the private and the public, exactly in the same way that outgoing President Lula da Silva acted during the presidential campaign. Journalism status quo emerged as a main topic in the coverage as a free press under attack quickly reacted with rage causing a rift between news organizations that criticized the outgoing president and those that supported him. Furthermore, a popular president apparently unaffected by corruption scandals and the country’s most powerful media groups confronted each other in an exhaustive and unfinished battle.

    De Seta, Marismary Horsth; Dain, Sulamis

    2010-11-01

    This paper analyzes the Brazilian Sanitary Surveillance System as an arrangement aimed at regulating and reducing health risks associated with consumption of products, use of health services and the environment. Historical, political and tax aspects were considered and their development compared with the National Health Surveillance System, which has received strong international cooperation. The comparison was based on the trajectory of their national systems and related federal agencies, as well as on criteria adopted for decentralization. The central category of analysis is federative coordination and was based on the framework of federalism and intergovernmental relations. The institutional context of health and sanitary surveillance presents strong political competition, instability in the project and probable reduction of the ability of federal coordination after the Pact for Health. The National Sanitary Surveillance System due to its nature of public good and high externality in its field of action requires federal coordination for increasing the regional and local cooperation, also because of the structural heterogeneity of Brazilian municipalities.

    Full Text Available The gradual development of the control systems and management of information about the organizations environment through measurement systems made, in this day and age, the reflection of reality. For the Brazilian franchise system this relationship is not different, evidenced by the variation of more than three times the amount raised in comparison to gross revenues achieved since 2001. Given this scenario of growth, this article has for primary objective to propose a performance measurement system for a segment of existing franchises in Brazil, through the elaboration of indicators related to external factors considered business critical success factors, based on financial and non-financial data made available publicly by the Brazilian Franchising Association (ABF. As a result, five performance indicators were developed for the system in question, in addition to the application of this model in a specific thread within the franchise system for the purpose of analyzing the information obtained and testing the reliability of the parameters used, identifying both that the model is reliable in accordance with the criteria established.

  5. Screening for thyroid disorders in asymptomatic adults from Brazilian populations

    Isabela Benseñor

    Full Text Available Advances in thyroid disorder diagnosis have created new thyroid disorder categories such as subclinical hyperthyroidism and subclinical hypothyroidism. In the 1980s, immunometric assaying for thyroid stimulating hormone (TSH emerged and became defined as the most cost-effective test in thyroid disorder screening. The second step in the screening of thyroid disorders is to determine free thyroxine (FT4, and cost-effective methods for its detection are now available. Using TSH and FT4, it is possible to determine four situations: clinical hyperthyroidism, clinical hypothyroidism, subclinical hyperthyroidism and subclinical hypothyroidism. Subclinical hypothyroidism can be a strong indicator of risk for atherosclerosis and myocardial infarction in elderly women. Cardiovascular mortality among Brazilian women is one of the highest in the Western world. The best-known risk factors for cardiovascular diseases are high blood pressure, smoking, diabetes, and hypercholesterolemia. Although these are recognized as primary risk factors, there are other risk factors that could be identified as primordial risk factors. This may be the case for subclinical hypothyroidism. Early detection of thyroid disorders in women over fifty could be a highly cost-effective option in the prevention of cardiovascular disorders among Brazilian women.

    Full Text Available OBJECTIVES: The aim of this study was to report the type and frequency of ocular manifestations in Brazilian psoriatic arthritis patients. METHODS: We conducted a cross-sectional study in a Brazilian tertiary hospital. The test group included 40 patients who had psoriatic arthritis according to the Classification Criteria for Psoriatic Arthritis. A control group of 40 individuals was matched for age and gender. All of the patients underwent ophthalmic evaluation, which included best-corrected visual acuity, slit lamp and fundus examinations, and dry eye diagnostic tests (Schirmer I, tear breakup time and rose bengal. Demographic parameters were also evaluated. RESULTS: The mean age of the patients was 53.9±13.1 years; the mean disease duration was 8±10.5 years. Most of the patients were women (60%, and the majority had polyarticular disease (57.5%. Several ocular abnormalities were found, including punctate keratitis, pinguecula, blepharitis, pterygium, cataract, glaucoma, uveitis, and retinal microvascular abnormalities. There were no significant differences in the rates of these abnormalities compared with the control group, however. The Keratoconjunctivitis sicca and dry eye diagnostic tests were more often positive in the patients with psoriatic arthritis than in the control group. CONCLUSIONS: In this study, keratoconjunctivitis sicca was the most common ocular finding related to psoriatic arthritis. Therefore, we recommend early ophthalmologic evaluations for all psoriatic arthritis patients who complain of eye symptoms.

    The notification of the Human Immunodeficiency Virus (HIV) in Brazilian children was first reported in 1984. Since that time more than 21 thousand children became infected. Approximately 99.6% of the children aged less than 13 years old are vertically infected. In this context, most of the children are abandoned after birth, or lose their relatives in a near future, growing with uncertain identification. The present study aims to estimate the dental age of Brazilian HIV patients in face of healthy patients paired by age and gender. The sample consisted of 160 panoramic radiographs of male (n: 80) and female (n: 80) patients aged between 4 and 15 years (mean age: 8.88 years), divided into HIV (n: 80) and control (n: 80) groups. The sample was analyzed by three trained examiners, using Willems' method, 2001. Intraclass Correlation Coefficient (ICC) was applied to test intra- and inter-examiner agreement, and Student paired t-test was used to determine the age association between HIV and control groups. Intra-examiner (ICC: from 0.993 to 0.997) and inter-examiner (ICC: from 0.991 to 0.995) agreement tests indicated high reproducibility of the method between the examiners (Page estimation of both HIV and healthy children with unknown age.

  8. Musical instruments of Brazilian capoeira: Historical roots, symbolism, and use

    2002-11-01

    This paper describes the historical roots, symbolism, and uses of musical instruments in capoeira. A martial art form of Afro-Brazilian origin, capoeira is rhythmically performed to music in a roda (i.e., circle). Capoeira is at times defined as a martial art form disguised as dance because it is rooted in the struggles of African slaves. Elements of music, dance, fight, and ritual are part of this unique martial art form, which has two main styles: Angola and Regional. Capoeira styles are important as they determine rhythmic patterns, chant, movement, and musical instrumentation in a roda. The leading instrument in all capoeira styles is the berimbau. The instrument dictates the rhythm and movement of capoeira players in a roda (Ilari, 2001). Made out of a wooden stick, a wire, and a gourd and played with a stick and a coin, the berimbau is considered a sacred instrument due to its association with the cry of the slaves. Other instruments used in capoeira are pandeiros, agogo bells, reco-recos, and atabaques. A discussion regarding the use of these instruments within the context of capoeira will be presented at the conference. The incorporation of these instruments into contemporary Brazilian music will also be considered.

    Brazilian agriculture covers about one-third of the land area and is expected to expand further. We assessed the compliance of present Brazilian agriculture with environmental legislation and identified challenges for agricultural development connected to this legislation. We found (i) minor illegal land use in protected areas under public administration, (ii) a large deficit in legal reserves and protected riparian zones on private farmland, and (iii) large areas of unprotected natural vegetation in regions experiencing agriculture expansion. Achieving full compliance with the environmental laws as they presently stand would require drastic changes in agricultural land use, where large agricultural areas are taken out of production and converted back to natural vegetation. The outcome of a full compliance with environmental legislation might not be satisfactory due to leakage, where pristine unprotected areas become converted to compensate for lost production as current agricultural areas are reconverted to protected natural vegetation. Realizing the desired protection of biodiversity and natural vegetation, while expanding agriculture to meet food and biofuel demand, may require a new approach to environmental protection. New legal and regulatory instruments and the establishment of alternative development models should be considered.

    Peptic and/or duodenal ulcers are characterized by diverse acute and chronic ulcerative lesions that commonly arise in any portion of the gastric mucosa that is exposed to the aggressive action of gastric acid. The pathophysiology of peptic ulcers has been attributed to an imbalance between aggressive and protective factors. In Brazil, medicinal plants are commonly used to treat this ailment. A country with great biodiversity, Brazil is considered a rich source of therapeutic products. There have been popular and pharmacological reports on the medicinal relevance of the Brazilian cerrado plant species, including Ananas ananassoides, Celtis iguanaea, Encholirium spectabile, Hymenaea stigonocarpa, Lafoensia pacari, Qualea grandiflora, Qualea parvifora, Mouriri pusa, Solanum lycocarpum, Solanum paniculatum, Serjania erecta, and Vochysia tucanorum, in the treatment of stomach disorders. The aim of the present review was to report on some of the Brazilian cerrado plants that are used in folk medicine because of their gastroprotective potential and to encourage novel studies in the search and preservation of plants with this therapeutic potential.

    We assess the water balance of the Brazilian Cerrado based on remotely sensed estimates of precipitation (TRMM), evapotranspiration (MOD16), and terrestrial water storage (GRACE) for the period from 2003 to 2010. Uncertainties for each remotely sensed data set were computed, the budget closure was evaluated using measured discharge data for the three largest river basins in the Cerrado, and the Mann-Kendall test was used to evaluate temporal trends in the water balance components and measured river discharge. The results indicate an overestimation of discharge data, due mainly to the overestimation of rainfall by TRMM version 6. However, better results were obtained when the new release of TRMM 3B42 v7 was used instead. Our results suggest that there have been (a) significant increases in average annual evapotranspiration over the entire Cerrado of 51 ± 15 mm yr-1, (b) terrestrial water storage increases of 11 ± 6 mm yr-1 in the northeast region of the Brazilian Cerrado, and (c) runoff decreases of 72 ± 11 mm yr-1 in isolated spots and in the western part of the State of Mato Grosso. Although complete water budget closure from remote sensing remains a significant challenge due to uncertainties in the data, it provides a useful way to evaluate trends in major water balance components over large regions, identify dry periods, and assess changes in water balance due to land cover and land use change.

    The aim was to analyse the physical growth and body composition of rhythmic gymnastics athletes relative to their level of somatic maturation. This was a cross-sectional study of 136 athletes on 23 teams from Brazil. Mass, standing height and sitting height were measured. Fat-free and fat masses, body fat percentages and ages of the predicted peak height velocity (PHV) were calculated. The z scores for mass were negative during all ages according to both WHO and Brazilian references, and that for standing height were also negative for all ages according to WHO reference but only until 12 years old according to Brazilian reference. The mean age of the predicted PHV was 12.1 years. The mean mass, standing and sitting heights, body fat percentage, fat-free mass and fat mass increased significantly until 4 to 5 years after the age of the PHV. Menarche was reached in only 26% of these athletes and mean age was 13.2 years. The mass was below the national reference standards, and the standing height was below only for the international reference, but they also had late recovery of mass and standing height during puberty. In conclusion, these athletes had a potential to gain mass and standing height several years after PHV, indicating late maturation.

    Full Text Available OBJECTIVE: Estimate the intake of phenolic compounds by the Brazilian population. METHODS: To estimate the average per capita food consumption, micro data from the National Dietary Survey and from the Household Budget Survey from 2008 to 2009 was analyzed. The phenolic content in food was estimated from the base of Phenol-Explorer. It was chosen according to compatibility and variety of food items and usual method of preparation. RESULTS: The Brazilian population consumed, on average, 460.15 mg/day of total phenolic compounds, derived mainly from beverages (48.9%, especially coffee and legumes (19.5%. Since this analysis of classes of phenolics it was possible to observe an intake of 314 mg/day of phenolic acids, 138.92 mg/day of flavonoids and 7.16 mg/ day of other kinds of phenolics. Regarding the variables studied this present study shows that those men who live in the countryside and in the northeastern region of the country had a higher consumption of phenolic compounds. Besides, consumption was higher by adults and the elderly, the medium income classes, the population with incomplete and complete primary education and those with adequate nutrition and also overweight status. CONCLUSION: The intake of phenolic compounds can be considered low, especially where consumption of fruit and vegetables is insufficient. We can conclude that coffee and black beans were the best contributors to phenolic intake.

    Full Text Available Microbial ecology and chemical composition of Brazilian kefir beverage was performed. The microorganisms associated with Brazilian kefir were investigated using a combination of phenotypic and genotypic methods. A total of 359 microbial isolates were identified. Lactic acid bacteria (60.5% were the major isolated group identified, followed by yeasts (30.6% and acetic acid bacteria (8.9%. Lactobacillus paracasei (89 isolates, Lactobacillus parabuchneri (41 isolates, Lactobacillus casei (32 isolates, Lactobacillus kefiri (31 isolates, Lactococcus lactis (24 isolates, Acetobacter lovaniensis (32 isolates, Kluyveromyces lactis (31 isolates, Kazachstania aerobia (23 isolates, Saccharomyces cerevisiae (41 isolates and Lachancea meyersii (15 isolates were the microbial species isolated. Scanning electron microscopy showed that the microbiota was dominated by bacilli (short and curved long cells growing in close association with lemon-shaped yeasts cells. During the 24 h of fermentation, the protein content increased, while lactose and fat content decreased. The concentration of lactic acid ranged from 1.4 to 17.4 mg/ml, and that of acetic acid increased from 2.1 to 2.73 mg/ml. The production of ethanol was limited, reaching a final mean value of 0.5 mg/ml.

  15. Securitization in the Brazilian Banking Industry: An Empirical Study

    Umbelina Cravo Teixeira Lagioia

    2009-05-01

    Full Text Available Securitization is a modality of structured finance which allows a company to raise funds based on its receivables through capital markets. In Brazil, securitization was developed mostly in the form of mutual funds -- the FIDC, which raise money by issuing senior quotas for qualified investors, and subordinated cotes, usually bought by the company that originated the receivables. This paper evaluates the risk and return for both kinds of investors through a stochastic model with two main variables: interest rates and default rates. The model is still sensible to the characteristics of the fund, like the amount of subordinated cotes, the type of asset being securitized; and the amount of receivables in relation to the assets. Regarding the case of senior cotes, the risk of returns under the basic level of interest rates is highly improbable; and in the case of subordinated cotes, the risk of returns under the basic interest rate may be considered still low, due to the high spreads observed in the Brazilian financial market. The simulations indicated that under historically mean interest rate volatility the default rates are the main component of the total risk. Accordingly to the developed analysis of international standards of regulation, the Brazilian Central Bank imposes very strong capital requirements to banks that securitize their assets and purchase the corresponding subordinated cotes.

    Full Text Available Approximately 57% of the Brazilian Northeast region is recognized as semiarid land and has been undergoing intense land use processes in the last decades, which have resulted in severe degradation of its natural assets. Therefore, the objective of this study is to identify the areas that are susceptible to desertification in this region based on the eleven driving factors of desertification (pedology, geology, geomorphology, topography data, land use and land cover change, aridity index, livestock density, rural population density, fire hot spot density, human development index (HDI, conservation units which were model-simulated for two different periods: 2000 and 2010. Each indicator were assigned weights ranging from 1 to 2 (representing the best and the worst conditions, representing classes indicating low, moderate and high susceptibility to desertification. The result indicates that 94% of the Brazilian Northeast region is under moderate to high susceptibility to desertification. The areas that were susceptible to soil desertification increased by approximately 4.6% (83.35 km2 from 2000 to 2010. The implementation of the methodology provide the technical basis for decision making that involves mitigating actions, as well as the first comprehensive national assessment within the United Nations Convention to Combat Desertification framework.

    Japanese-Brazilians were the third largest immigrant group in Japan in 2011. Their health issues have caused concern, as their limited language made them vulnerable by hindering access to health services. Upon considering child health, mothers' health literacy (HL) is very important. This study aimed to develop a health literacy scale among Brazilian mothers (HLSBM) in Japan. Questionnaires in Portuguese were distributed to 1474 mothers from December 2011 to March 2012. Among 698 collected, 558 questionnaires were analyzed. We prepared 29 candidate items for HLSBM based on Nutbeam's concept of functional, interactive and critical literacy. The dimensional structure was determined statistically using confirmatory factor analysis. Validity was also analyzed by Pearson's correlation with Ishikawa's scale and Kendall's coefficient of concordance among researchers. Cronbach's α coefficients were calculated to examine internal consistency. The confirmatory factor analysis revealed a two-factor model (five items for basic literacy and five items for critical literacy) with sufficient goodness of fit (GFI 969, AGFI 945, NFI 959, CFI 972, RMSEA 060). The internal consistency values of the total score, basic and critical literacy sub-scales were 0.819, 0.889 and 0.667, respectively. Kendall's coefficient of concordance showed good agreement of researchers (p literacy and 0.472 for critical literacy. The HLSBM consisting of two factors was confirmed to be valid and reliable. The HLSBM must be useful for understanding this vulnerable group's health literacy and its associated factors.

    Full Text Available The elaboration of profile characteristics that can serve as parameters in the different categories and investment in scientific studies of Brazilian volleyball have shown their importance in developing new athletes. In this sense, the objective of the descriptive study in question was to analyze important characteristics such as somatotype and anthropometry in the Brazilian under-17 and under-18 national teams, respectively. The population was composed of 33 (14 females and 19 males athletes from the aforementioned teams. We used a high-precision scale and stadiometer to verify anthropometric characteristics and Heath & Carter’s method to evaluate somatotype. The men’s team obtained the following mean results: Age = 16.71; height = 195.9cm; body weight = 87.7kg; endomorphy = 1.26; mesomorphy = 3.18 and ectomorphy = 3.8; while the women’s results were: Age = 15.9; height = 181.6cm; body weight = 67.4kg; endomorphy = 3.09; mesomorphy = 2.21 and ectomorphy = 3.88. We can conclude from the results that the teams in question have similar characteristics to those of the high-performance adult teams, and exhibit a predominance of the ectomorphic component of the somatotype. This finding is of great importance, given the current demands of high-performance volleyball, and shows us the high level of the group studied.

    2015-07-01

    Full Text Available Nosocomial infection is notoriously one of the primary problems faced by healthcare insti-tutions and by professionals who work for them. This fact is demonstrated by the growing number of legal actions proposed in the legal system by patients and users of the health care system. Because of this scenario, the phenomenon of civil liability has arisen in cases of noso-comial infection. The legal implications of this phenomenon are varied and involve issues of the institutional environment and of professional conduct. Thus, the current study seeks to analyze the literature on the decisions taken by Brazilian courts regarding civil liability in cases of nosocomial infection. Conceptual aspects that define this healthcare problem are listed, as are the types of civil liability, the legal directives that guide conduct regarding this topic, and the decisions of Brazilian courts that consider civil liability in these cases. It was determined that the courts have been supported by the distinction between objective civil liability and subjective civil liability; additionally, it was determined that these courts are guided by the understanding of the existing service relationship between the institution or health care professional and the patient or user of the health care system.

    Renata Trajano Borges Jorge

    Full Text Available CONTEXT AND OBJECTIVE: Body image improvement is considered to be the main reason for undergoing plastic surgery. The objective was to translate the Body Dysmorphic Disorder Examination (BDDE into Brazilian Portuguese and to adapt and validate this questionnaire for use in Brazil. DESIGN AND SETTING: Cross-sectional survey, at the Department of Plastic Surgery of Universidade Federal de São Paulo. METHODS: The BDDE was first translated into Portuguese and then back-translated into English. These translations were then discussed by healthcare professionals in order to establish the final Brazilian version. In a second stage, the validity and reliability of the BDDE were assessed. For this, patients were initially interviewed by two interviewers and subsequently, by only one of these interviewers. On the first occasion, in addition to the BDDE, the body shape questionnaire (BSQ and the Rosenberg self-esteem scale were also applied. These questionnaires were applied to 90 patients. RESULTS: Six questions were modified during the assessment of cultural equivalence. Cronbach's alpha was 0.89 and the intraclass correlation coefficients for interobserver and test-retest reliability were 0.91 and 0.87, respectively. Pearson's coefficient showed no correlation between the BDDE and the Rosenberg self-esteem scale (0.22, whereas there was a moderate correlation between the BDDE and the BSQ (0.64. CONCLUSIONS: The BDDE was successfully translated and adapted, with good internal consistency, reliability and construct validity.

    Full Text Available Comparative studies show significant results when compared with fiscal transparency social indicators in the framework of democratic processes. However, careful analysis of the consequences associated with fiscal transparency are still surprisingly scarce. The aim of this research is to verify the existence of relationship between fiscal transparency and local development in the Brazilian states. The theoretical framework is related to public budget, focusing on fiscal transparency, and social development. In addition, to control social development by groups of Brazilian regions, we use a dummy variable. Therefore, this paper contributes to find empirical evidence on the existence of directly proportional relationship between state fiscal transparency and local development in Brazil. Moreover, it is important to highlight that the regional issue is fundamental to explaining social development, which together with fiscal transparency should be consider essential for formulation and implementation of public policies focus on the reducing of poverty and inequality in Brazil. Therefore, we expect that his article collaborated with data and ideas in order to stimulate further studies related to the consequences of fiscal transparency, considering all government levels: state, municipality and federal.

    Full Text Available The species of the genus Lychnophora, Asteraceae, are popularly known as "arnica" and are native from Brazilian savana (Cerrado. They are widely used in Brazilian folk medicine as anti-inflammatory, to treat bruise, pain, rheumatism and for insect bites. For evaluation of acute toxicity, the ethanolic extract was given to albino female and male mice. In open-field test, the extract of Lychnophora trichocarpha (Spreng. Spreng. (0.750 g/kg induced a significant inhibition of the spontaneous locomotor activity and exploratory behavior of the animals were observed 1 and 4 h after administration. In traction test, the same dose reduced the muscular force 1 h after administration. The exploratory behavior reduced significantly in the group that received 0.50 g/kg, 1 and 4 h after administration of the extract. The animals that received the doses of 0.25, 0.50 and 0.75 g/kg did not show any change of blood biochemical parameters comparing to control group and showed some histopathological changes such as congestion and inflammation of kidney and liver. The dose of 1.5 g/kg caused the most serious signs of toxicity. Histopathological changes observed was hemorrhage in 62.5% and pulmonary congestion in 100% of the animals. Brain and liver congestion was found in 62.5% of the animals.

    In this paper we studied the research activity of Brazilian Institutions for all sciences and also their performance in the area of physics between 1945 and December 2008. All the data come from the Web of Science database for this period. The analysis of the experimental data shows that, within a nonextensive thermostatistical formalism, the Tsallis \\emph{q}-exponential distribution $N(c)$ can constitute a new characterization of the research impact for Brazilian Institutions. The data examined in the present survey can be fitted successfully by applying a universal curve namely, $N(c) \\propto 1/[1+(q-1) c/T]^{\\frac{1}{q-1}}$ with $q\\simeq 4/3$ for {\\it all} the available citations $c$, $T$ being an "effective temperature". The present analysis ultimately suggests that via the "effective temperature" $T$, we can provide a new performance metric for the impact level of the research activity in Brazil, taking into account the number of the publications and their citations. This new performance metric takes int...

    Full Text Available This study sought to validate the Portuguese translation of a questionnaire on maltreatment of children and adolescents, developed by Russell et al. and to test its psychometric properties for use in Brazil. The original questionnaire was translated into Portuguese using a standardized forward-backward linguistic translation method. Both face and content validity were tested in a small pilot study (n = 8. In the main study, a convenience sample of 80 graduate dentistry students with different specialties, from Curitiba, PR, Brazil, were invited to complete the final Brazilian version of the questionnaire. Discriminant validity was assessed by comparing the results obtained from the questionnaire for different specialties (pediatric dentistry, for example. The respondents completed the questionnaire again after 4 weeks to evaluate test-retest reliability. The comparison of test versus retest questionnaire answers showed good agreement (kappa > 0.53, intraclass correlation > 0.84 for most questions. In regard to discriminant validity, a statistically significant difference was observed only in the experience and interest domains, in which pediatric dentists showed more experience with and interest in child abuse compared with dentists of other specialties (Mann-Whitney test, p < 0.05. The Brazilian version of the questionnaire was valid and reliable for assessing knowledge regarding child abuse by Portuguese-speaking dentists.

    2006-03-01

    Full Text Available A sample of 103 randomly chosen healthy individuals from Alegrete, RS, Brazil, was tested for the CCR5delta32 allele, which is known to influence susceptibility to HIV-1 infection. The CCR5delta32 allele was identified by PCR amplification using specific primers flanking the region of deletion, followed by electrophoresis on a 3% agarose gel. The data obtained were compared to those reported for other populations and interpreted in terms of Brazilian history. The individuals studied came from a highly admixed population. Most of them were identified as white (N = 59, while blacks and browns (mulattoes were N = 13 and N = 31, respectively. The observed frequencies, considering the white, black and brown samples (6.8, 3.8, and 6.4%, respectively, suggest an important European parental contribution, even in populations identified as black and brown. However, in Brazil as a whole, this allele shows gradients indicating a relatively good correlation with the classification based on skin color and other physical traits, used here to define major Brazilian population groups.

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

    2007-01-01

    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.

    Full Text Available Objective: To define the sagittal balance and spinopelvic parameters in a Brazilian population sample composed of asymptomatic volunteers. Methods: Fifty healthy adult individuals volunteered to participate in this study. The exclusion criteria included spinal deformity or improper radiograph study. In each radiograph exam in profile view, the sagittal balance and spinopelvic parameters were evaluated, including vertical sagittal axis, sacral slope, pelvic tilt and pelvic incidence. Results: The data obtained in this study are according to the values presented in the worldwide literature. None of the radiographic parameters showed any differences between the genders. Comparing the values presented in this study with those of other reports, with different populations, it was observed that: there was no significant difference in any of the pelvic parameters between Brazilian and Korean populations; there was a significant difference in pelvic incidence between Brazilian and European populations in a total sample (p=0.0001, in males (p=0.02, and in females (p=0.0007; there was a difference in sacral slope between Brazilian and European populations in a total sample (p=0.0140, and in females (p=0.005. Conclusion: There were no differences in any parameter in terms of gender. There were no differences in pelvic incidence between Brazilian and Korean populations. There was a difference in pelvic incidence between Brazilian and European populations, in the total sample and in males and females. There was a difference in sacral slope between Brazilian and European populations in a total sample, and in females.

  10. Fishing for gaps in science: a bibliographic analysis of Brazilian freshwater ichthyology from 1986 to 2005.

    2010-06-01

    To investigate Brazilian freshwater ichthyology, from 1986 to 2005, a bibliometric analysis was conducted using abstracts downloaded from The Web of Science database searching for the keywords 'fish', 'pisces', 'teleostei' and the address field having the word 'Brazil'. The results of this study showed that Brazilian freshwater ichthyology publications have been increasing during the study period. This process is a consequence of a series of investments that the Brazilian Government has made. Furthermore, data analyses identified scientific areas where there was a lack of scientific knowledge (e.g. studies of species threatened with extinction and certain hydrologic basins). Research institutions from the north-east and northern region of Brazil had the lowest participation in scientific productivity, which was a reflection of their regions poorer economic situation. This study showed that scientific productivity in Brazilian ichthyology was a direct reflection of state investment in research. Furthermore, data in this study follow expected statistical probabilities, for example, fishes from the most diverse families were the most studied. Thus, the study shows that great progress has been made by Brazilian ichthyologists in the last 20 years; however, due to the mega diversity of fishes in Brazil, much remains to be done if many species are to become known to science and to be saved from extinction. This it seems will depend on continued and further investment by Brazilian Government funding agencies, as Brazilian ichthyologists have demonstrated their capacity to generate high quality information about their study species.

    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.

    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.

    2006-06-01

    Full Text Available This paper uses 1992:1-2004:2 quarterly data and two different methods (approximation under lognormality and calibration to evaluate the existence of an equity-premium puzzle in Brazil. In contrast with some previous works in the Brazilian literature, I conclude that the model used by Mehra and Prescott (1985, either with additive or recursive preferences, is not able to satisfactorily rationalize the equity premium observed in the Brazilian data. The second contribution of the paper is calling the attention to the fact that the utility function calculated under the discrete-state approximation may not exist if the data (as it is the case with Brazilian time series implies the existence of states in which high negative rates of consumption growth are attained with relatively high probability. This fact is particularly important when the researcher tries to work with high risk-aversion parameters in order to generate high risk premia.Este trabalho usa dados brasileiros do período 1992:1-2004:2 e dois diferentes métodos (aproximação sob a hipótese de lognormalidade e calibração para avaliar a existência de um "equity-premium puzzle" no Brasil. Em contraste com alguns trabalhos prévios da literatura nacional, conclui-se que o modelo usado por Mehra and Prescott (1985, seja com preferências aditivas ou recursivas, não é capaz de gerar o prêmio de risco observado na economia brasileira. A segunda contribuição do trabalho é chamar a atenção para o fato de que a função utilidade calculada sob a hipótese de aproximação discreta do espaço de estados pode não existir se os dados (como é o caso no Brasil implicarem a existência de estados nos quais taxas altamente negativas de crescimento do consumo são alcançadas com probabilidade demasiado elevadas. Este fato é particularmente importante quando se tenta utilizar parâmetros de aversão ao risco altos o suficiente para gerar o prêmio de risco inerente ao caso brasileiro.

    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

    ABSTRACT OBJECTIVE To evaluate the prevalence of leisure-time physical inactivity in Brazilian adolescents and their association with geographical and sociodemographic variables. METHODS The sample was composed by 74,589 adolescents participating in the Study of Cardiovascular Risks in Adolescents (ERICA). This cross-sectional study of school basis with national scope involved adolescents aged from 12 to 17 years in Brazilian cities with more than 100 thousand inhabitants. The prevalence of leisure-time physical inactivity was categorized according to the volume of weekly practice (< 300; 0 min). The prevalences were estimated for the total sample and by sex. Poisson regression models were used to assess associated factors. RESULTS The prevalence of leisure-time physical inactivity was 54.3% (95%CI 53.4-55.2), and higher for the female sex (70.7%, 95%CI 69.5-71.9) compared to the male (38.0%, 95%CI 36.7-39.4). More than a quarter of adolescents (26.5%, 95%CI 25.8-27.3) reported not practicing physical activity in the leisure time, a condition more prevalent for girls (39.8%, 95%CI 38.8-40.9) than boys (13.4%, 95%CI 12.4-14.4). For girls, the variables that were associated with physical inactivity were: reside in the Northeast (RP = 1.13, 95%CI 1.08-1.19), Southeast (RP = 1.16, 95%CI 1.11-1.22) and South (RP = 1.12, 95%CI 1.06-1.18); have 16-17 years (RP = 1.06, 95%CI 1.12-1.15); and belong to the lower economic class (RP = 1.33, 95%CI 1.20-1.48). The same factors, except reside in the Southeast and South, were also associated with not practicing physical activity in the leisure time for the same group. In males, as well as the region, being older (p < 0.001) and declaring to be indigenous (RP = 0.37, 95%CI 0.19-0.73) were also associated with not practicing physical activities in the leisure time. CONCLUSIONS The prevalence of leisure-time physical inactivity in Brazilian adolescents is high. It presents regional variations and is associated with age and low

    Full Text Available The 2008 economic crisis challenged accounting, either demanding recognition and measurement criteria well adjusted to this scenario or even questioning its ability to inform appropriately entities’ financial situation before the crisis occurred. So, our purpose was to verify if during economic crises listed companies in the Brazilian capital market tended to adopt earnings management (EM practices. Our sample consisted in 3,772 firm-years observations, in 13 years – 1997 to 2009. We developed regression models considering discretionary accruals as EM proxy (dependent variable, crisis as a macroeconomic factor (dummy variable of interest, ROA, market-to-book, size, leverage, foreign direct investment (FDI and sector as control variables. Different for previous EM studies two approaches were used in data panel regression models and multiple crises were observed simultaneously. Statistics tests revealed a significant relation between economic crisis and EM practices concerning listed companies in Brazil in both approaches used.

    2015-12-01

    Full Text Available This article was developed from a chapter in a doctoral thesis from the first author, towards a specific focalized discussion, related to the practice of simultaneous interpretation in Brazilian Sign Language, based on translation modalities as proposed by Aubert (1998. The interpreted text is called “Discovering who we are”, extracted from the book Learning to see, by Sherman, Wilcox and Phyllis, and translated by Tarcisio de Arantes Leite. The interpretations were recorded in a media studio, with the official consent from the Ethics Committee for Research with Human Beings at the Federal University of Santa Catarina, Brazil and the data was analyzed by means of the software ELAN. Results indicate that using a research method which considers translation modalities may contribute to obtain a clearer view regarding the similarities and differences between the selected linguistic pairs.

  1. The interiorization of Brazilian violence, policing, and economic growth

    2015-09-01

    Full Text Available Brazilian homicide rates are among the highest in the world, inclusive of actual war zones. However, the character of Brazil's violence is changing. Recent analyses highlight a trend of dispersion of violence such that homicide rates in urban areas, traditionally the most violent places, have stagnated and declined while smaller cities and rural areas experienced a marked increase. An incipient explanation is that this trend is related to greater economic dynamism in the smaller cities, unaccompanied by increased policing. This article's empirical analysis uses locational Hoover indexes to express the dispersions of violence and economic activity, and also generates a proxy to measure the geographic concentration of police forces. Using panel data across all 26 states from 1995 to 2011, we find evidence of a correlation between dispersion of violence and GDP to less urban areas, and ambiguous results regarding police concentration.

    Dental elements are valuable tools in a study of ancient populations and species, and key-features for human identification; among the dental anthropology field, nonmetric traits, standardized by ASUDAS, are closely related to ancestry. This study aimed to analyze the frequency of six nonmetric traits in a sample from Southeast Brazil, composed by 130 dental casts from individuals aged between 18 and 30, without foreign parents or grandparents. A single examiner observed the presence or absence of shoveling, Carabelli's cusp, fifth cusp, 3-cusped UM2, sixth cusp, and 4-cusped LM2. The frequencies obtained were different from the ones shown by other researches to Amerindian and South American samples, and related to European and sub-Saharan frequencies, showing the influence of this groups in the current Brazilian population. Sexual dimorphism was found in the frequencies of Carabelli's cusp, 3-cusped UM2, and sixth cusp.

    We respond to Valle and Clark,1 who assert that “conservation efforts may increase malaria burden in the Brazilian Amazon,” because the relationship between forest cover and malaria incidence was stronger than the effect of the deforestation rate.1 We contend that their conclusion is flawed because of limitations in their methodology that we discuss in detail. Most important are the exclusion of one-half the original data without a discussion of selection bias, the lack of model adjustment for either population growth or migration, and the crude classifications of land cover and protected areas that lead to aggregation bias.1 Of greater significance, we stress the need for caution in the interpretation of data that could have profound effects on regional land use decisions.

    Full Text Available This article aims at analyzing the development of and changes in, the repertoire and strategies for action of the Brazilian feminist movement, in the period between the democratic “re-opening” set in the 1980s and the first decade of the XXI century. Our interest is centered in two foci of analysis: on the one hand, it focuses on the movement’s positioning in relation to the State, which varied from a situation of opposition, or even of indifference, to direct attempts at influencing public policies and actions in the State sphere, whether through party politics or participative institutions. On the other hand, we are interested in analyzing how, and in which specific moments, agency beyond the national feminist frontiers takes place and in which measure this influences the local repertoires and vice-versa.

    2010-03-01

    Full Text Available Cleaner Production (CP is gaining emphasis in both world and Brazilian production sectors. Nature’s warnings indicating the exhaustion of any capacity to absorb and regenerate waste, stricter legislation regarding pollution emitters, market competitiveness associated with environmental and social responsibility cause concerns and lead to actions to reduce aggressions against the environment. This paper shows evidence of this concern and presents cases in which a large automotive industry, acting as a partner to suppliers, promotes changes in how it delivers its products, eliminating large cardboard, plastic and wood packaging. A small company had a similar initiative, reducing the use of cardboard and plastic packaging. More important is the revelation of a widely dispersed, yet growing and incremental movement of responsibilities among companies.The benefits of cleaner production implementation were evaluated by confronting environmental and financial assessment. For the ambient evaluation, it will be used methodology of Material Intensity (Wuppertal Institute, a.

    Full Text Available Dissociated motor development (DMD is considered when the baby starts independent walking late, with normality of the other fields of development. There is evidence that babies with DMD present an atypical crawling pattern and hypotonia. To investigate the frequency and characteristics of DMD, neurological examination was performed monthly in 177 healthy full-term babies from 6 months age, in urban and rural zone samples in Brazil. Among 20 children with atypical crawling, none presented hypotonia neither did they start independent walking late. The means of the ages at the begining of atypical crawling and independent walking acquisitions, 7.40mo (SD 1.4 and 12.76mo (SD 2.5 respectively, did not differ from the group with crossed crawling pattern. Thus, in this sample of Brazilian healthy children we did not find cases with DMD.

    Trichuris trichiura is a soil-transmitted helminth which is prevalent in warm, moist, tropical and subtropical regions of the world with poor sanitation. Heavy whipworm can result either in Trichuris dysenteric syndrome - especially in children - or in a chronic colitis. In heavy infections, worms can spread proximally and may cause ileitis. Here we provide first microscopic evidence for a T. trichiura adult worm embedded in the rectum of a post-Colonial Brazilian adult mummy. During Colonial and post-Colonial times, many European chroniclers described a parasitic disease named Maculo whose symptomatology coincides with heavy helminthiasis. Based on our findings and on comparison of ancient textual evidence with modern description of heavy whipworm, we feel confident in considering that the two syndromes are expressions of the same pathological condition.

    2013-08-01

    Full Text Available The objective of this work was to estimate the genetic variability level and distribution in Brazilian broodstocks of marine shrimp (Litopenaeus vannamei. Nine of the country's largest hatcheries were evaluated using codominant and highly polymorphic microsatellite markers. The results obtained from genotyping of ten microsatellite loci are indicative of genetic variability that is compatible with that found in wild populations of L. vannamei in Mexico and Central America. A possible explanation is the highly diversified and relatively recent origin of the available broodstocks. Bayesian analysis detected a signal for five founding populations. The distribution of genetic distances partially reflects geographical location, and this information will be useful for the creation of new broodstocks. Therefore, L. vannamei genetic variability among nine of the largest national hatcheries can be considered high.

    Ten captive neotropical Brazilian feline were submitted to gastroscopic examination and samples of gastric mucosa from fundus, corpus and pyloric antrum were evaluated for the presence of Helicobacter species. Warthin-Starry (WS) staining and PCR assay with species-specific primers and enzymatic cleavage were applied for bacterial detection and identification. Histological lesions were evaluated by haematoxylin and eosin staining. All animals showed normal gross aspect of gastric mucosa. Helicobacter heilmannii was confirmed in 100% of the samples by WS and PCR assay. Mild lymphocytic infiltrate in the lamina propria was observed in eight animals, mainly in the fundus region. Small lymphoid follicles were seen in three animals. No significant association between Helicobacter infection and histological findings was verified. These observations suggest that gastric Helicobacter spp. could be a commensal or a eventual pathogen to captive neotropical feline, and that procedures, way life, and stress level on the shelter apparently had no negative repercussion over the integrity of the stomach.

    2007-06-01

    Full Text Available This paper analyses the relationship between idiosyncratic risk and diversified portfolio returns on Brazil’s capital market. Following Goyal and Santa-Clara (2003 and Bali et alii (2005 we use volatility measures that capture systematic and idiosyncratic risk. For the identification of the relationship between idiosyncratic risk and portfolio returns we use a time series framework regressing volatility measures and portfolio returns one step ahead from 1999:01 to 2006:03. Additionally, we carry out robustness tests to validate our results. We found no evidence of a relationship between idiosyncratic risk and portfolio returns for the Brazilian capital market. Our evidence is similar to those from Bali et alii (2005 for the US capital market, which challenges the Goyal e Santa-Clara (2003 findings.

    We compared the rickettsial infection status of Amblyomma cajennense ticks, humans, dogs, and horses in both Brazilian spotted fever (BSF)-endemic and -nonendemic areas in the state of Sao Paulo, Brazil. Most of the horses and few dogs from BSF-endemic areas had serologic titers against Rickettsia rickettsii antigens. In contrast, no dogs or horses from BSF-nonendemic areas had serologic titers against R. rickettsii antigens, although they were continually exposed to A. cajennense ticks. All human serum samples and ticks from both areas were negative by serologic assay and polymerase chain reaction, respectively. Our results indicate that surveys of horse serum are a useful method of BSF surveillance in areas where humans are exposed to A. cajennense ticks. In addition, we successfully performed experimental infection of A. cajennense ticks with R. parkeri.

    Full Text Available We investigate minimum variance portfolios in the Brazilian equity market using different methods to estimate the covariance matrix, from the simple model of using the sample covariance to multivariate GARCH models. We compare the performance of the minimum variance portfolios to those of the following benchmarks: (i the IBOVESPA equity index, (ii an equally-weighted portfolio, (iii the maximum Sharpe ratio portfolio and (iv the maximum growth portfolio. Our results show that the minimum variance portfolio has higher returns with lower risk compared to the benchmarks. We also consider long-short 130/30 minimum variance portfolios and obtain similar results. The minimum variance portfolio invests in relatively few stocks with low βs measured with respect to the IBOVESPA index, being easily replicable by individual and institutional investors alike.

    Sustainable intensification of agriculture is one of the main strategies to provide global food security. However, its implementation raises enormous political, technological, and social challenges. Meeting these challenges will require, among other things, accurate information on the spatial and temporal patterns of agricultural land use and yield. Here, we investigate historical patterns of agricultural land use (1940-2012) and productivity (1990-2012) in Brazil using a new high-resolution (approximately 1 km(2) ) spatially explicit reconstruction. Although Brazilian agriculture has been historically known for its extensification over natural vegetation (Amazon and Cerrado), data from recent years indicate that extensification has slowed down and was replaced by a strong trend of intensification. Our results provide the first comprehensive historical overview of agricultural land use and productivity in Brazil, providing clear insights to guide future territorial planning, sustainable agriculture, policy, and decision-making.

    Negroponte [1996. Being digital (1st ed.). New York, NY: Vintage Books] discusses the migration television might take from its air-based broadcasting to the digital environment. This paper takes into consideration the exercise in futurology made by Negroponte [1996. Being digital (1st ed.). New York, NY: Vintage Books] as an inspiration to discuss which Internet TV models are currently adopted in Brazil. They are studied in terms of the platforms used and the nature of the channels available. Results show that a number of devices can be used for Internet TV; some channels are redundant, since they are present in more than one context. There are a number of foreign (broadcasting in their own language) and Brazilian channels that seem to be exclusive in each device. Due to the price of some devices, as well as some issues regarding connectivity in Brazil, some platforms seem to lack local production.

    2012-09-01

    The primary and secondary feathers of 170 Brazilian psittacine birds (Aves: Psittaciformes) were examined in order to identify feather quill mite fauna. Birds were held captive in two locations in the state of Minas Gerais (MG), and two in the state of Espirito Santo (ES). The quills were cut longitudinally and were examined under optical microscopy. The genus of quill mites most frequently found was Paralgopsis (Astigmata: Pyrogliphidae), followed by Cystoidosoma (Astigmata: Syringobiidae). Astigmata: Syringophilidae mites were sporadically observed. After analyzing the data using logistic regression models, it was determined that there was higher infestation risk for psittacines in ES state, as compared with those in MG, and a significant increase in risk depending on the psittacine host species. However, the location of captivity did not have a significant effect. Lesions were observed in infested feathers. Cystoidosoma sp. and Paralgopsis sp. were always observed together, with parts of Paralgopsis found inside Cystoidosoma sp., suggesting thanatochresis or predation.

    Integrative review, held in the databases LILACS, SciELO and BDENF from January 2005 to May 2009, aimed to summarize the Brazilian scientific production based on Orem's Nursing Theory. We obtained 23 articles, analyzed by simple descriptive statistics. It was found that 100% of the studies focused on adults. Of this total, 65,22% returned to the chronicle diseases. In 39,15% of the searches, the theory was used in full and in 34,80% one of the constructs. 91,30% of publications aimed to the construction and deployment of the structured and theoretically grounded practice of care. It was concluded that the theory has been used as theoretical and philosophical basis to justify the practice of nursing in a variety of situations in order to emphasize the role of the nurse in the care.

    2012-01-01

    Full Text Available Although common in Brazil, the biology of the fire ant Solenopsis saevissima (Smith is still poorly studied. Larval descriptions are useful to genus-level ant systematics and sometimes to species-level taxonomy. This study presents a detailed description of juveniles of S. saevissima from Brazil, which were compared with Brazilian specimens of Solenopsis invicta Buren, Solenopsis geminata (Fabricius, and Solenopsis altipunctata Pitts. Different larval instars were separated by diagnostic morphological traits which were confirmed by observing moults. Reproductive larvae could be easily sorted by their distinctive body dimensions and shape. Contrary to previous reports on this species, the larvae of S. saevissima proved to be generally identical to those of S. invicta, while a few specimens resembled those of other close species, such as Solenopsis megergates Trager. Mature larvae thus presented considerable intraspecific variation in some characters recently proposed to aid fire ant species separation (morphology of head hairs.

    Extracts from various organs of 25 plants of Brazilian traditional medicine were assayed with respect to their anti-bacterial activities against Escherichia coli, a susceptible strain of Staphylococcus aureus and two resistant strains of Staphylococcus aureus harbouring the efflux pumps NorA and MsrA. Amongst the 49 extracts studied, 14 presented anti-bacterial activity against Staphylococcus aureus, including the ethanolic extracts from the rhizome of Jatropha elliptica, from the stem barks of Schinus terebinthifolius and Erythrina mulungu, from the stems and leaves of Caesalpinia pyramidalis and Serjania lethalis, and from the stem bark and leaves of Lafoensia pacari. The classes of compounds present in the active extracts were determined as a preliminary step towards their bioactivity-guided separation. No extracts were active against Escherichia coli.

    The main development vector of a society is the energy. The solar energy is the main energy source on the planet earth. Brazil is a tropical country, and the incident solar energy on its soil (15 trillion MWh/year) is 20,000 times its annual oil production. Several uses of solar energy are part of our lives in a so natural way that it despised in the consumption and use energy balance. In Brazil, solar energy is used directly in many activities and not accounted for in Energy Balance (BEN 2007), consisting of a virtual power generation. This work aims to make a preliminary assessment of solar energy used in different segments of the Brazilian economy. (author)

    Full Text Available Pythium insidiosum is an oomycete belonging to the kingdom Stramenipila and it is the etiologic agent of pythiosis. Pythiosis is a life-threatening infectious disease characterized by the development of chronic lesions on cutaneous and subcutaneous, intestinal, and bone tissues in humans and many species of animals. The identification of P. insidiosum is important in order to implement a rapid and definitive diagnosis and an effective treatment. This study reports the identification of 54 isolates of P. insidiosum of horses, dogs and sheep that presented suspicious clinical lesions of pythiosis from different regions in Brazil, by using morphological and molecular assays. Throughout the PCR it was possible to confirm the identity of all Brazilian isolates as being P. insidiosum.

    2011-12-01

    Heterogeneous Forest Impacts of Transport Infrastructure: spatial frontier dynamics & impacts of Brazilian Amazon road changes Prior research on road impacts has almost completely ignored heterogeneity of impacts and as a result both empirically understated potential impact and missed policy potential. We note von Thunen's model suggests not only heterogeneity with distance from market but also specifically road impacts rising then falling with distance ('non-monoThunicity') Endogenous development and partial adjustment dynamics support this for the short run. Causal effects result from studying Brazilian Amazon deforestation (1976-87, 2000-04) using matching for short-run responses to lagged new roads changes (1968-75, 1985-00). We show the critical role of prior development, proxied by 1968 and 1985 road distances, for which exact matching addresses development trends and transforms impact estimates. Splitting the sample on this measure finds confirmation of the nonmonotonic predictions: new road impacts are relatively low if a prior road was close, such that prior transport access and endogenous development dynamics compete with the new road for influence, but also if a prior road was far, since first-decade adjustment in pristine areas is limited; yet in between these bounds, investments immediately raise deforestation significantly. This pattern helps to explain lower estimates within research on a single average impact. It suggests potential for REDD if a country chooses to shift its spatial transport networks. Protected Areas & Brazilian Amazon Deforestation: modeling and testing the impacts of varied PA strategies We model and then estimate the impacts of multiple types of protected areas upon 2000 - 2004 deforestation in the Brazilian Amazon. Our modeling starts with federal versus state objectives and predicts differences in both choice and implementation of each PA strategy that we examine. Our empirical examination brings not only breakdowns sufficient

    Full Text Available This paper provides a description of the wave climate off the Brazilian coast based on an eleven-year time series (Jan/1997-Dec/2007 obtained from the NWW3 operational model hindcast reanalysis. Information about wave climate in Brazilian waters is very scarce and mainly based on occasional short-term observations, the present analysis being the first covering such temporal and spatial scales. To define the wave climate, six sectors were defined and analyzed along the Brazilian shelf-break: South (W1, Southeast (W2, Central (W3, East (W4, Northeast (W5 and North (W6. W1, W2 and W3 wave regimes are determined by the South Atlantic High (SAH and the passage of synoptic cold fronts; W4, W5 and W6 are controlled by the Intertropical Convergence Zone (ITCZ and its meridional oscillation. The most energetic waves are from the S, generated by the strong winds associated to the passage of cold fronts, which mainly affect the southern region. Wave power presents a decrease in energy levels from south to north, with its annual variation showing that the winter months are the most energetic in W1 to W4, while in W5 and W6 the most energetic conditions occur during the austral summer. The information presented here provides boundary conditions for studies related to coastal processes, fundamental for a better understanding of the Brazilian coastal zone.O presente trabalho apresenta o clima de ondas da região ao largo da costa brasileira com base em uma série temporal de onze anos (Jan/1997-Dez/2007 obtida através de dados de reanálise do modelo operacional NWW3.

    Full Text Available In order to collaborate with the academic debate about the social construction of economic tools, this article captures the social construction of the Corporate Sustainability Index (ISE of Bovespa. From an economic approach, the index is the numeric representation of financial profitability of sustainable enterprises, however, from that of sociology, the ISE is the window to apprehend the symbolic struggles that constitute the Brazilian market of Socially Responsible Investment (SRI. This idea is demonstrated by the recovery of the chronological history of the development of ISE which shows the elements of the arbitrary political process searching for its economic neutrality. This article emphasizes the need to explore sociologically the financial indexes as well as other classification tools of the economic world.

    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.

    The Brazilian cerrado, or savanna, spans an area of 1,800,000 square kilometers on the great plateau of Central Brazil. Large fires covering hundreds of square kilometers, frequently occur in wildland areas of the cerrado, dominated by grasslands or grasslands mixed with shrubs and small trees, and also within area in the cerrado used for agricultural purposes, particularly for grazing. Smaller fires, typically extending over arm of a few square kilometers or less, are associated with the clewing of crops, such as dry land rice. A method for mapping fire scars and differentiating them from extensive areas of bare sod with AVHRR bands 1 (.55 -.68 micrometer) and 3 (3.5 - 3.9 micrometers) and measures of performance based on comparison with maps of fires with Landsat imagery will be presented. Methods of estimating total area burned from the AVHRR fire scar map will be discussed and related to land use and scar size.

    Full Text Available The aim of this paper was to analyze the determinings of farm work allocation in Brazilian regions, based on micro data of National Household Sample Survey 2009. For that, the empirical procedure consisted in the use of two models: Confirmatory Factor Analysis and the Logit Model. The model Confirmatory Factor Analysis showed good fit and defined two latent variables: qualification and income. As to the Logit Model, the results showed that the fact of a man living in rural areas increases the likelihood of being allocated in farm work, however if he is white this probability decrease. Besides, the variables qualification and income have a negative relation with farm work allocation, being the Midwest region that contributed most for people being allocated in farm work.

    Full Text Available This work investigates the effects of Employee Stock Options Plans (ESOP on the value of companies in the Brazilian Stock Exchange (BM&FBOVESPA. An ESOP is a mechanism of variable compensation, generally offered to executives, having the alignment of interests between managers and shareholders as one of its goals. To achieve this purpose, a panel data analysis was used in order to try measuring if the ESOP generated or not value to shareholders. The results show that there is evidence that the ESOP only generates wealth for shareholders when it is well-set, specifically when the exercise price is fixed at-money or out-of-money. An increase in the stock price is also achieved when companies adopt best practices of corporate governance and the ESOP by more than three years.

    Full Text Available The aim of this work is to identify the tensile strength of alumina (Corbit98, by performing Brazilian tests at different loading rate. In this kind of test, generally used for brittle material in static loading conditions, a cylindrical specimen is diametrically compressed and failure is generated in the middle of the component as a consequence of a positive tensile stress. In this work, this experimental technique was applied also in dynamic loading conditions by using a setup based on the Split Hopkinson Pressure Bar. Due to the properties of the investigated material, among which are high hardness, high compressive strength, and brittle behaviour, some precautions were needed to assure the validity of the tests. Digital Image Correlation techniques were applied for the analysis of high framerate videos.

    Biodiversity hotspots, representing regions with high species endemism and conservation threat, have been mapped globally. Yet, biodiversity distribution data from within hotspots are too sparse for effective conservation in the face of rapid environmental change. Using frogs as indicators, ecological niche models under paleoclimates, and simultaneous Bayesian analyses of multispecies molecular data, we compare alternative hypotheses of assemblage-scale response to late Quaternary climate change. This reveals a hotspot within the Brazilian Atlantic forest hotspot. We show that the southern Atlantic forest was climatically unstable relative to the central region, which served as a large climatic refugium for neotropical species in the late Pleistocene. This sets new priorities for conservation in Brazil and establishes a validated approach to biodiversity prediction in other understudied, species-rich regions.

    Trichuris trichiura is a soil-transmitted helminth which is prevalent in warm, moist, tropical and subtropical regions of the world with poor sanitation. Heavy whipworm can result either in Trichuris dysenteric syndrome - especially in children - or in a chronic colitis. In heavy infections, worms can spread proximally and may cause ileitis. Here we provide first microscopic evidence for a T. trichiura adult worm embedded in the rectum of a post-Colonial Brazilian adult mummy. During Colonial and post-Colonial times, many European chroniclers described a parasitic disease named Maculo whose symptomatology coincides with heavy helminthiasis. Based on our findings and on comparison of ancient textual evidence with modern description of heavy whipworm, we feel confident in considering that the two syndromes are expressions of the same pathological condition.

    2004-01-01

    The Brazilian shield was assembled from a few Archean and Paleoproterozoic cratonic nuclei surrounded by Pan-African-Brasiliano mobile belts of Neoproterozoic age. While some of these mobile belts display a typical frontal collision tectonic style, others are dominated by transcurrent regimes, clearly indicating oblique collisional systems. This paper is an attempt to determine the mean orientation of the principal horizontal compressive stresses for each mobile belt, considering either the frontal or oblique convergence character. From these general observations a scheme with WNW - ESE to NWSE trends of the main compressive stress is proposed. We suggest that this trend represents the mean displacement vectors, according to a coherent kinematic picture for the amalgamation of the West Gondwana during the final stages of convergence of the Brasiliano belts, where WNW-ESE to NW-SE are the main directions of final closure.

    Care for the emotional needs of hospitalized children has had the attention of nursing professionals in Brazil, although not as a general rule. The chance to play is known as a relief from suffering, especially in childhood, which justifies the importance of this theme. This study had the objective of analyzing Brazilian nurses' academic production on the use of toys during the attention to children in hospitals in strictu sensu Graduate programs. Data were taken from Portal CAPES, CEPEn, IBICT and papers' references. Of the 15 theses/dissertations found in the literature only 14 are available; they were analyzed and comprise the corpus of this study. It was found that toys have been used mostly in pre and postsurgery, by Nursing professors, with preschool and school age children, parents and nurses. All of the works reinforce the positive results of toys' use. We recommend to pediatric nurses the use of toys in all institutions where children need care.

    2016-08-01

    Full Text Available More than 80% of the Brazilian population inhabits urban areas. Diffused poverty and the lack of fresh vegetables have generated malnutrition and unbalanced diets. Thus, the interest in growing food locally, in urban allotments and community gardens, has increased. However, urban agriculture may present some risks caused by the urban pollution. Road traffic is considered the biggest source of heavy metals in urban areas. Hence, the objective of the study was the assessment of the accumulation of heavy metals in an urban garden in the city of Recife, at different distances from a road with high traffic burden. The results showed that the distance from the street decreased the accumulation of many potentially toxic elements. Furthermore, the human health risk was estimated, revealing that greater danger was associated with the accumulation of antimony. Concentration of other elements in the leaf tissues were within previously reported thresholds.

  5. Brazilian pharmaceutical diplomacy: social democratic principles versus soft power interests.

    2013-01-01

    Current debates concerning the rise of health diplomacy are polarized between competing international relations theories of realism, based on power politics, and constructivist approaches, which emphasize the norms, values, and identities shaping foreign policies. A case study of Brazil's health diplomacy over the past 10 years, focusing on issues related to pharmaceuticals, seeks to provide data to assess these theories. The country's intellectual property disputes, multilateral lobbying efforts, and foreign assistance programs are contrasted with those of the United States, Mexico, and other countries. Instead of viewing Brazilian efforts as a form of soft power, the evidence suggests that the origins of Brazil's involvement and continued efforts in this arena stem more from values based on human rights and social democratic principles. A close examination of domestic political considerations leads to a more nuanced understanding of the drivers behind a country's health diplomacy.

    Full Text Available Since the announcement of Lula’s throat cancer on October 2011, the risks presented to the voice of Brazil’ former president gave rise to a wide range of comments. Based on Discourse Analysis derived from Michel Pêcheux in this essay we propose to analyze them in terms of their different positions and their distinct meanings. We further undertake a reflexion on certain aspects of Brazilian history, which are preserved in the voice of one of the most important personalities in the country, in order to answer the following questions: Why was Lula’s voice mentioned a number of times? What are the positions and implications of these comments? What role did his voice play in his public speeches, in the composition of his charisma, and in his political success?

    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.

    Cardiac Anxiety (CA) is the fear of cardiac sensations, characterized by recurrent anxiety symptoms, in patients with or without cardiovascular disease. The Cardiac Anxiety Questionnaire (CAQ) is a tool to assess CA, already adapted but not validated to Portuguese. This paper presents the three phases of the validation studies of the Brazilian CAQ. To extract the factor structure and assess the reliability of the CAQ (phase 1), 98 patients with coronary artery disease were recruited. The aim of phase 2 was to explore the convergent and divergent validity. Fifty-six patients completed the CAQ, along with the Body Sensations Questionnaire (BSQ) and the Social Phobia Inventory (SPIN). To determine the discriminative validity (phase 3), we compared the CAQ scores of two subgroups formed with patients from phase 1 (n = 98), according to the diagnoses of panic disorder and agoraphobia, obtained with the MINI - Mini International Neuropsychiatric Interview. A 2-factor solution was the most interpretable (46.4% of the variance). Subscales were named 'Fear and Hypervigilance' (n = 9; alpha = 0.88), and 'Avoidance', (n = 5; alpha = 0.82). Significant correlation was found between factor 1 and the BSQ total score (p < 0.01), but not with factor 2. SPIN factors showed significant correlations with CAQ subscales (p < 0.01). In phase 3, 'Cardiac with panic' patients scored significantly higher in CAQ factor 1 (t = -3.42; p < 0.01, CI = -1.02 to -0.27), and higher, but not significantly different, in factor 2 (t = -1.98; p = 0.51, CI = -0.87 to 0.00). These results provide a definite Brazilian validated version of the CAQ, adequate to clinical and research settings.

    Full Text Available This paper examines, for the first time in the literature, the impact of trade unions on various performance indicators of Brazilian establishments. A unionism retrospective survey was carried out among 1,000 establishments in the manufacturing sector and its results were matched to performance indicators available from the Brazilian Industrial Surveys between 1990 and 2000. The results using the pooled data indicate that the relationship between unionism and some performance indicators, such as average wages, employment and productivity is non-linear (concave, so that a rise in unionism from low levels is associated with higher performance, but at a decreasing rate. Unions also reduce profitability. Establishments that introduced profit-sharing schemes increased their productivity and profitability overall and paid higher wages in more unionized plants.Este artigo analisa, pela primeira vez na literatura, o impacto dos sindicatos de trabalhadores em vários indicadores de desempenho econômico de firmas industriais brasileiras. Realizou-se uma pesquisa retrospectiva sobre a densidade sindical de 1000 estabelecimentos industriais brasileiros e seus resultados foram combinados aos indicadores de desempenho econômico da Pesquisa Industrial Anual (PIA de 1990 a 2000. Os resultados indicam que a relação entre a densidade sindical na firma e seus salários, emprego e produtividade, é não-linear, ou seja, um aumento no grau de sindicalização leva a um melhor desempenho, porém a taxas decrescentes. Observou-se, também, uma relação negativa entre sindicalização e rentabilidade. Finalmente, estabelecimentos que introduziram mecanismos de 'participação nos lucros' aumentaram sua produtividade e rentabilidade no período e pagaram maiores salários nas firmas onde o grau de sindicalização era maior.

    OBJECTIVE To describe the prevalence of eating habits considered healthy in adolescents according to sex, age, education level of the mother, school type, session of study, and geographic region. METHODS The assessed data come from the Study of Cardiovascular Risks in Adolescents (ERICA), a cross-sectional, national and school-based study. Adolescents of 1,247 schools of 124 Brazilian municipalities were evaluated using a self-administered questionnaire with a section on aspects related to eating behaviors. The following eating behaviors were considered healthy: consuming breakfast, drinking water, and having meals accompanied by parents or legal guardians. All prevalence estimates were presented proportionally, with their respective 95% confidence intervals. The Chi-square test was used to evaluate the differences in healthy eating habits prevalences according to other variables. The module survey of the Stata program version 13.0 was used to analyze complex data. RESULTS We evaluated 74,589 adolescents (72.9% of the eligible students). Of these, 55.2% were female, average age being 14.6 years (SD = 1.6). Among Brazilian adolescents, approximately half of them showed healthy eating habits when consuming breakfast, drinking five or more glasses of water a day, and having meals with parents or legal guardians. All analyzed healthy eating habits showed statistically significant differences by sex, age, type of school, session of study, or geographic region . CONCLUSIONS We suggest that specific actions of intersectoral approach are implemented for the dissemination of the benefits of healthy eating habits. Older female adolescents (15 to 17 years old) who studied in public schools, resided in the Southeast region, and whose mothers had lower education levels, should be the focus of these actions since they present lower frequencies concerning the evaluated healthy habits.

    2014-01-01

    Perspectives on invasive and noninvasive ventilatory support for critically ill patients are evolving, as much evidence indicates that ventilation may have positive effects on patient survival and the quality of the care provided in intensive care units in Brazil. For those reasons, the Brazilian Association of Intensive Care Medicine (Associação de Medicina Intensiva Brasileira - AMIB) and the Brazilian Thoracic Society (Sociedade Brasileira de Pneumologia e Tisiologia - SBPT), represented by the Mechanical Ventilation Committee and the Commission of Intensive Therapy, respectively, decided to review the literature and draft recommendations for mechanical ventilation with the goal of creating a document for bedside guidance as to the best practices on mechanical ventilation available to their members. The document was based on the available evidence regarding 29 subtopics selected as the most relevant for the subject of interest. The project was developed in several stages, during which the selected topics were distributed among experts recommended by both societies with recent publications on the subject of interest and/or significant teaching and research activity in the field of mechanical ventilation in Brazil. The experts were divided into pairs that were charged with performing a thorough review of the international literature on each topic. All the experts met at the Forum on Mechanical Ventilation, which was held at the headquarters of AMIB in São Paulo on August 3 and 4, 2013, to collaboratively draft the final text corresponding to each sub-topic, which was presented to, appraised, discussed and approved in a plenary session that included all 58 participants and aimed to create the final document.

    Full Text Available The automotive business in Brazil achieved 10% of the industry revenue and 6% of the formal employment by 2008. The commercial vehicle segment concentrated so far eight truck makers that experienced their best market figures in 2008, the economy crisis in 2009, and an extraordinary recovery in 2010. Government tax reduction programs as well as special financing incentives were undoubtedly decisive to re-stimulate the business during the crisis. Positive Brazilian perspectives with the boom in the agricultural, oil and gas, mining and infrastructure activities plus the coming sports events call the attention of new players that are quickly implementing different business strategies to become part of the game. New emission regulations starting from 2012 also bring uncertainties, challenges and opportunities. With the growing globalization and market concentration it's critical for any industry understand and minimize the forces of competitive pressures. The main goal of this paper, therefore, is to contribute to the academy with an alternative approach of strategic and behavioral analysis of rivalry and competition different than the five forces model of Porter. Ford, Iveco, MAN, Mercedes-Benz, Scania and Volvo were assessed from 2008 to 2010 within three main performance indicators – unit sales, gross revenues and operating profits – supporting the elaboration of the competitive pressure systems mapping model of D'aveni, including a hypothetical future scenario with a new entrant and the potential impacts in the system. Main findings and results portray the asymmetrical strategic behavior of competitors and the temporary dynamic stability in the Brazilian truck industry.

    AIM: To evaluate the prevalence and clinical characteristics of Nonalcoholic fatty liver disease (NAFLD) among asymptomatic Brazilian adolescents.METHODS: Transversal observational study included asymptomatic adolescents with central obesity from private and public schools in Salvador-Bahia, northeastern Brazil. The children answered a questionnaire that included age, gender, race, and medical history, and were submitted to a complete physical exam and abdominal ultrasound. Biochemical exams included: ALT, AST, GGT,C reactive protein (CRP), fasting glucose, insulin, cholesterol and triglycerides. Criteria for NAFLD included: the presence of steatosis in ultrasound and/or high level of ALT, negative or occasional historic of intake of alcohol (≤ 140 g/wk), negative investigation for hepatitis A, B, C,auto-immune hepatitis, Wilson disease and hemochromatosis.RESULTS: From October, 2005 to October, 2006, the study included 1801 subjects between 11 and 18 years of age and a mean age of 13.7±2.0 years.One hundred ninety-nine had central obesity. The prevalence of NAFLD was 2.3%, most of whom were male and white. Insulin resistance (IR) was observed in 22.9% of them and had positive correlations with ALT and GGT ( P < 0.05). Elevated CRP was observed in 6.9% of the cases; however, it was not associated with WC,IR or liver enzymes.CONCLUSION: The prevalence of NAFLD in Brazilian adolescents was low. The ethnicity may have influence this frequency in the population studied, which had a large proportion of African descendents.

    Full Text Available OBJECTIVE: Hereditary angioedema is a serious medical condition caused by a rare autosomal dominant genetic disorder and it is associated with deficient production or dysfunction of the C1 esterase inhibitor. In most cases, affected patients experience unexpected and recurrent crises of subcutaneous, gastrointestinal and laryngeal edema. The unpredictability, intensity and other factors associated with the disease impact the quality of life of hereditary angioedema patients. We evaluated the quality of life in Brazilian hereditary angioedema patients. METHODS: Patients older than 15 years with any severity of hereditary angioedema and laboratory confirmation of C1 inhibitor deficiency were included. Two questionnaires were used: a clinical questionnaire and the SF-36 (a generic questionnaire. This protocol was approved by the Ethics Committee of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. RESULTS: The SF-36 showed that 90.4% (mean of all the patients had a score below 70 and 9.6% had scores equal to or higher than 70. The scores of the eight dimensions ranged from 51.03 to 75.95; vitality and social aspects were more affected than other arenas. The internal consistency of the evaluation was demonstrated by a Cronbach's alpha value above 0.7 in seven of the eight domains. CONCLUSIONS: In this study, Brazilian patients demonstrated an impaired quality of life, as measured by the SF-36. The most affected domains were those related to vitality and social characteristics. The generic SF-36 questionnaire was relevant to the evaluation of quality of life; however, there is a need for more specific instruments for better evaluation.

    ABSTRACT OBJECTIVE To describe the patterns of alcohol consumption in Brazilian adolescents. METHODS We investigated adolescents who participated in the Study of Cardiovascular Risks in Adolescents (ERICA). This is a cross-sectional, national and school-based study, which surveyed adolescents of 1,247 schools from 124 Brazilian municipalities. Participants answered a self-administered questionnaire with a section on alcoholic beverages consumption. Measures of relative frequency (prevalence), and their 95% confidence intervals, were estimated for the following variables: use of alcohol beverages in the last 30 days, frequency of use, number of glasses or doses consumed in the period, age of the first use of alcohol, and most consumed type of drink. Data were estimated for country and macro-region, sex, and age group. The module survey of the Stata program was used for data analysis of complex sample. RESULTS We evaluated 74,589 adolescents, who accounted for 72.9% of eligible students. About 1/5 of adolescents consumed alcohol at least once in the last 30 days and about 2/3 in one or two occasions during this period. Among the adolescents who consumed alcoholic beverages, 24.1% drank it for the first time before being 12 years old, and the most common type of alcoholic beverages consumed by them were drinks based on vodka, rum or tequila, and beer. CONCLUSIONS There is a high prevalence of alcohol consumption among adolescents, as well as their early onset of alcohol use. We also identified a possible change in the preferred type of alcoholic beverages compared with previous research. PMID:26910550

    The Ministry of Health coordinates and orients in Brazil all the activities concerning the acquired immunodeficiency syndrome which is officially designated as AIDS. The first AIDS' case registered in Brazil was, by retrospective diagnosis, in 1981 but it was in 1982 that the first two diagnosis in live patients were made. The incidence is very high in this country that is among the ones where the higher number of cases are being registered. The great majority of the Brazilian cases occurs in the cities and in direct proportion to the population index. The groups of risk are the same universally known and a comparative increase of heterosexual transmission is noted, chiefly due to the use of injectable drugs and bisexuality of the male partners. Another problem that is being increased is pediatric AIDS, with raising importance of perinatal transmission as well as the use of injectable drugs and precocious prostitution in adolescence. The transfusional and haemophilic AIDS have proportionally decreased due to the control of blood products. The control and the orientation activity of the Ministry of Health is directed to varied points such as: compulsory cases notification, cooperation between public and private sectors, preventive and sexual orientation, freely delivered medication and laboratory tests including sigilous tests, lay and technical personnel preparation, diversified informative and educational campaigns. Trial tests with anti-HIV vaccines have begun to be performed. Multiple Reference Centers were officially established by the administration. Among them is to be quoted the Hospital Universitário Gaffrée Guinle of Rio de Janeiro where the authors work. It is credited for its intensive activity and pioneerism. In this Institution special attention was due against discrimination of HIV-infected patients, to diagnosis, to anonymous and sigilous tests, to medical and psychological assistance, to myocardium involvement, to the virologic study of the

    Perspectives on invasive and noninvasive ventilatory support for critically ill patients are evolving, as much evidence indicates that ventilation may have positive effects on patient survival and the quality of the care provided in intensive care units in Brazil. For those reasons, the Brazilian Association of Intensive Care Medicine (Associação de Medicina Intensiva Brasileira - AMIB) and the Brazilian Thoracic Society (Sociedade Brasileira de Pneumologia e Tisiologia - SBPT), represented by the Mechanical Ventilation Committee and the Commission of Intensive Therapy, respectively, decided to review the literature and draft recommendations for mechanical ventilation with the goal of creating a document for bedside guidance as to the best practices on mechanical ventilation available to their members. The document was based on the available evidence regarding 29 subtopics selected as the most relevant for the subject of interest. The project was developed in several stages, during which the selected topics were distributed among experts recommended by both societies with recent publications on the subject of interest and/or significant teaching and research activity in the field of mechanical ventilation in Brazil. The experts were divided into pairs that were charged with performing a thorough review of the international literature on each topic. All the experts met at the Forum on Mechanical Ventilation, which was held at the headquarters of AMIB in São Paulo on August 3 and 4, 2013, to collaboratively draft the final text corresponding to each sub-topic, which was presented to, appraised, discussed and approved in a plenary session that included all 58 participants and aimed to create the final document.

    Full Text Available ABSTRACT OBJECTIVE To describe the prevalence of eating habits considered healthy in adolescents according to sex, age, education level of the mother, school type, session of study, and geographic region. METHODS The assessed data come from the Study of Cardiovascular Risks in Adolescents (ERICA, a cross-sectional, national and school-based study. Adolescents of 1,247 schools of 124 Brazilian municipalities were evaluated using a self-administered questionnaire with a section on aspects related to eating behaviors. The following eating behaviors were considered healthy: consuming breakfast, drinking water, and having meals accompanied by parents or legal guardians. All prevalence estimates were presented proportionally, with their respective 95% confidence intervals. The Chi-square test was used to evaluate the differences in healthy eating habits prevalences according to other variables. The module survey of the Stata program version 13.0 was used to analyze complex data. RESULTS We evaluated 74,589 adolescents (72.9% of the eligible students. Of these, 55.2% were female, average age being 14.6 years (SD = 1.6. Among Brazilian adolescents, approximately half of them showed healthy eating habits when consuming breakfast, drinking five or more glasses of water a day, and having meals with parents or legal guardians. All analyzed healthy eating habits showed statistically significant differences by sex, age, type of school, session of study, or geographic region . CONCLUSIONS We suggest that specific actions of intersectoral approach are implemented for the dissemination of the benefits of healthy eating habits. Older female adolescents (15 to 17 years old who studied in public schools, resided in the Southeast region, and whose mothers had lower education levels, should be the focus of these actions since they present lower frequencies concerning the evaluated healthy habits.

    2016-01-01

    ABSTRACT OBJECTIVE To describe the methodological characteristics of the studies selected and assess variables associated with sedentary behavior in Brazilian children and adolescents. METHODS For this systematic review, we searched four electronic databases: PubMed, Web of Knowledge, LILACS, SciELO. Also, electronic searches were applied in Google Scholar. A supplementary search was conducted in the references lists of the included articles and in non-indexed journals. We included observational studies with children and adolescents aged from three to 19 years developed in Brazil, presenting analyses of associations based on regression methods and published until September 30, 2014. RESULTS Of the 255 potential references retrieved by the searches, 49 met the inclusion criteria and composed the descriptive synthesis. In this set, we identified a great number of cross-sectional studies (n = 43; 88.0%) and high methodological variability on the types of sedentary behavior assessed, measurement tools and cut-off points used. The variables most often associated with sedentary behavior were “high levels of body weight” (in 15 out of 27 studies; 55.0%) and “lower level of physical activity” (in eight out of 16 studies; 50.0%). CONCLUSIONS The findings of this review raise the following demands to the Brazilian agenda of sedentary behavior research geared to children and adolescents: development of longitudinal studies, validation of measuring tools, establishment of risk cut-offs, measurement of sedentary behavior beyond screen time and use of objective measures in addition to questionnaires. In the articles available, the associations between sedentary behavior with “high levels of body weight” and “low levels of physical activity” were observed in different regions of Brazil.

    Full Text Available BACKGROUND: Group A Streptococcus (GAS clinical and molecular epidemiology varies with location and time. These differences are not or are poorly understood. METHODS AND FINDINGS: We prospectively studied the epidemiology of GAS infections among children in outpatient hospital clinics in Brussels (Belgium and Brasília (Brazil. Clinical questionnaires were filled out and microbiological sampling was performed. GAS isolates were emm-typed according to the Center for Disease Control protocol. emm pattern was predicted for each isolate. 334 GAS isolates were recovered from 706 children. Skin infections were frequent in Brasília (48% of the GAS infections, whereas pharyngitis were predominant (88% in Brussels. The mean age of children with GAS pharyngitis in Brussels was lower than in Brasília (65/92 months, p<0.001. emm-typing revealed striking differences between Brazilian and Belgian GAS isolates. While 20 distinct emm-types were identified among 200 Belgian isolates, 48 were found among 128 Brazilian isolates. Belgian isolates belong mainly to emm pattern A-C (55% and E (42.5% while emm pattern E (51.5% and D (36% were predominant in Brasília. In Brasília, emm pattern D isolates were recovered from 18.5% of the pharyngitis, although this emm pattern is supposed to have a skin tropism. By contrast, A-C pattern isolates were infrequently recovered in a region where rheumatic fever is still highly prevalent. CONCLUSIONS: Epidemiologic features of GAS from a pediatric population were very different in an industrialised country and a low incomes region, not only in term of clinical presentation, but also in terms of genetic diversity and distribution of emm patterns. These differences should be taken into account for designing treatment guidelines and vaccine strategies.

    Full Text Available Historical epistemology has played an important role in the development of modern Brazilian Public Health or “Saúde Coletiva” (Collective Health. Born as an academic search for new conceptual foundations of a social committed field of scientific knowledge, as well as a social political movement against civil-military dictatorship implanted in Brazil in 1964, the so called Brazilian Sanitary Reform Movement found in the French historical epistemology, particularly in the works of Georges Canguilhem, a powerful ally. This paper aims to revisit the main features of this relationship, focusing in particular the inaugural works of Sergio Arouca and Cecília Donnangelo and the Health Work Process Theory as developed in the Department of Preventive Medicine of the Medical School of the University of São Paulo. The discussion is centered in the way Canguilhem’s philosophical concepts, such as the normative character of life and of its knowledge, the qualitative discontinuity between normal and pathological phenomena and the value oriented definition of health on one hand, and on the other hand, Canguilhem’s historiographical method, focused on the rational development of concepts as the core subject of the historical-epistemological research, the acknowledge of “external” influences over scientific developments, such as social and technological conditions, and the positive role attributed to obstacles, failures and accidents in the progress of a scientific discipline were all crucial to promote the intertwining of the political and academic goals of the Movement and still remain a challenging element for the development of the philosophical and historical reflections of the field of “Saúde Coletiva”.

    Full Text Available The chemical composition of ethanol extracts from samples of Brazilian propolis (EEPs determined by HPLC and their activity against Trypanosoma cruzi, Staphylococcus aureus, Streptococcus pneumoniae, Klebisiella pneumoniae, Candida albicans, Sporothrix schenckii and Paracoccidioides brasiliensis were determined. Based on the predominant botanical origin in the region of samples' collection, the 10 extracts were separated into three groups: A (B. dracunculifolia + Auraucaria spp, B (B. dracunculifolia and C (Araucaria spp. Analysis by the multiple regression of all the extracts together showed a positive correlation, higher concentrations leading to higher biological effect, of S. aureus with p-coumaric acid (PCUM and 3-(4-hydroxy-3-(oxo-butenyl-phenylacrylic acid (DHCA1 and of trypomastigotes of T. cruzi with 3,5-diprenyl-4-hydroxycinnamic acid derivative 4 (DHCA4 and 2,2-dimethyl-6-carboxyethenyl-2H-1-benzopyran (DCBEN. When the same approach was employed for each group, due to the small number of observations, the statistical test gave unreliable results. However, an overall analysis revealed for group A an association of S. aureus with caffeic acid (CAF and dicaffeoylquinic acid 3 (CAFQ3, of S. pneumoniae with CAFQ3 and monocaffeoylquinic acid 2 (CAFQ2 and of T. cruzi also with CAFQ3. For group B, a higher activity against S. pneumoniae was associated DCBEN and for T. cruzi with CAF. For group C no association was observed between the anitmicrobial effect and any component of the extracts. The present study reinforces the relevance of PCUM and derivatives, especially prenylated ones and also of caffeolyquinic acids, on the biological activity of Brazilian propolis.

    Introduction The supratrochlear foramen is an anatomic variation of great clinical and anthropologic interest. Although many studies addressed this subject in different ethnic groups, there are no studies regarding Brazilians. Aim To verify the incidence and morphometric measures of the supratrochlear foramen in Brazilian humeri. Materials and Methods A total of 330 dry humeri were analysed and divided in three groups: bones presenting the supratrochlear foramen (Group 1), bones displaying a translucent foramen (Group 2) and humeri without the foramen (Group 3). The aperture was measured with a digital vernier caliper. Radiographic pictures with different incidences were taken. Results Our analysis showed that 22.5% of humeri belonged in Group 1, 41.2% in Group 2, and 36.3% in Group 3. The mean vertical diameter and the mean horizontal diameter of the supratrochlear foramen on the left side were 2.779±2.050 mm and 2.332±1.23 mm, respectively. The mean vertical diameter and the mean horizontal diameter of the foramen on the right side were 2.778±2.197 mm, and 2.365±1.396 mm, respectively. The student’s t-test showed that there was no significant difference regarding the size of the foramen between both sides. The best X-ray machine setup was 50 kilo voltage and 0.08 milliamperage per second, associated with a slight increase in the distance of the x-ray tube. Conclusion The aperture seems to be the key point during the pre-operative planning of intramedullary fixation, since it has direct relation to the size of the intramedullary canal, thus, being an entity of clinical, anatomical, anthropological, radiological, and surgical interest.

    Full Text Available Starting in the 1970's, the Brazilian agricultural sector has experienced an important process of modernization, whose principal effects include advances in technological progress and gains in productivity. The primary objective of this paper is to analyze technological progress and total productivity growth in the Brazilian agricultural sector during the period from 1970 to 1996. The methodology used here is based on the Malmquist productivity index and techniques in mathematical programming called Data Envelopment Analysis. The results show that significant progress was made in this sector of the economy but concentrated in only some regions of the country.O setor agropecuário brasileiro passou por um processo de modernização a partir dos anos 70, conseqüentemente, espera-se que exista uma contrapartida de progresso tecnológico e de ganhos de produtividade para o setor. Diante de tal fato tem-se como objetivo, neste estudo, avaliar o progresso tecnológico e o crescimento da produtividade total dos fatores (PTF do setor agropecuário brasileiro ao longo do período de 1970 a 1996. A metodologia utilizada foi baseada no índice Malmquist de produtividade e nas técnicas de programação matemática denominadas de Análise de Envoltória de Dados (DEA. Os resultados alcançados foram condizentes com estudos prévios e apontam para progresso técnico e ganhos de produtividade para o setor, porém concentrados em algumas regiões.

    Luiggi Araujo Lustosa

    Full Text Available CONTEXT AND OBJECTIVE: Impact factors are currently the bibliometric index most used for evaluating scientific journals. However, the way in which they are used, for instance concerning the study or journal types analyzed, can markedly interfere with estimate reliability. This study aimed to analyze the citation distribution pattern in three Brazilian journals of general medicine. DESIGN AND SETTING: This was a descriptive study based on numbers of citations of scientific studies published by three Brazilian journals of general medicine. METHODS: The journals analyzed were São Paulo Medical Journal, Clinics and Revista da Associação Médica Brasileira. This survey used data available from the Institute for Scientific Information (ISI platform, from which the total number of papers published in each journal in 2007-2008 and the number of citations of these papers in 2009 were obtained. From these data, the citation distribution was derived and journal impact factors (average number of citations were estimated. These factors were then compared with those directly available from the ISI Journal of Citation Reports (JCR. RESULTS: Respectively, 134, 203 and 192 papers were published by these journals during the period analyzed. The observed citation distributions were highly skewed, such that many papers had few citations and a small percentage had many citations. It was not possible to identify any specific pattern for the most cited papers or to exactly reproduce the JCR impact factors. CONCLUSION: Use of measures like "impact factors", which characterize citations through averages, does not adequately represent the citation distribution in the journals analyzed.

    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 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)

    Ana Patrícia de Paula

    Full Text Available CONTEXT AND OBJECTIVE: Scientific and technological development is crucial for advancing the Brazilian health system and for promoting quality of life. The way in which the Brazilian Ministry of Health has supported clinical research to provide autonomy, self-sufficiency, competitiveness and innovation for the healthcare industrial production complex, in accordance with the National Policy on Science, Technology and Innovation in Healthcare, was analyzed. DESIGN AND SETTING: Descriptive investigation, based on secondary data, conducted at the Department of Science and Technology, Ministry of Health. METHODS: The Ministry of Health's research management database, PesquisaSaúde, was analyzed from 2002 to 2009, using the key word "clinical research" in the fields "primary sub-agenda" or "secondary sub-agenda". The 368 projects retrieved were sorted into six categories: basic biomedical research, preclinical studies, expanded clinical research, clinical trials, infrastructure support and health technology assessment. From a structured review on "clinical research funding", results from selected countries are presented and discussed. RESULTS: The amount invested was R$ 140 million. The largest number of projects supported "basic biomedical research", while the highest amounts invested were in "clinical trials" and "infrastructure support". The southeastern region had the greatest proportion of projects and financial resources. In some respects, Brazil is ahead of other BRICS countries (Russia, India, China and South Africa, especially with regard to establishing a National Clinical Research Network. CONCLUSION: The Ministry of Health ensured investments to encourage clinical research in Brazil and contributed towards promoting cohesion between investigators, health policies and the healthcare industrial production complex.

    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.

    Full Text Available This paper uses the Liu et al. (2007 approach to estimate the optionimplied Risk-Neutral Densities (RND, real-world density (RWD, and relative risk aversion from the Brazilian Real/US Dollar exchange rate distribution. Our empirical application uses a sample of exchange-traded Brazilian Real currency options from 1999 to 2011. Our estimated value of the relative risk aversion is around 2.7, which is in line with other articles for the Brazilian Economy. Our out-of-sample results showed that the RND has some ability to forecast the Brazilian Real exchange rate, but when we incorporate the risk aversion, the out-of-sample performance improves substantially.

    The purpose of this study was to examine how key occupational therapy terminologies are used by Brazilian occupational therapists. A nominal group approach combined with a Delphi technique involving 31 Brazilian occupational therapists was applied. A sociolinguistic approach was adopted since it broadens our understanding of the social and cultural determinants of terminology consolidation. Brazilian occupational therapists were found to adopt the term activity more often than human action or doing. Even less often were praxis and occupation applied. No consensus was reached regarding which of the terms is most preferred. While Brazilian occupational therapists have been developing their profession from international standards, it is still embedded in local demands and policies. Additionally, the political context must be considered when building an international dialogue between members of a professional body. Such a dialogue could engage professionals from different countries in meaningful exchanges about their practices. These exchanges may lead to the development of solid professional communities that can contribute meaningfully to social change.

    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.
