    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

  3. Brazilian organic sugarcane spirits: Physicochemical and chromatographic profile

    Directory of Open Access Journals (Sweden)

    Felipe Cimino Duarte

    Full Text Available ABSTRACT There has been a growing demand for products from organic agriculture for the food market. Brazil leads the production of sugarcane spirits and produces about 1.6 billion liters/year. New technologies have been sought throughout the supply chain to improve production, and organic raw material has been used in the production of sugar cane for the production of beverages. This study aimed to define the physicochemical and chromatographic profiles of eleven organic sugarcane spirits samples from various Brazilian states. The secondary components and contaminants were identified and quantified through physicochemical analyses, HPLC and gas chromatography (GC. A significant percentage of the organic sugarcane spirits samples contained concentrations of components that were above the limits required by the Ministry of Agriculture, Livestock and Provisioning (MAPA, specifically the esters (18.20%, copper and dry extract (9.10%. This contamination is caused by bad conditions employed during the production process, which are not in compliance with the good manufacturing practices determined and legislated by Brazilian law.

  4. Complex organizations: the case of the Brazilian nuclear sector

    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)

  6. Trust within Brazilian New Economy Organizations: an Empirical Investigation of Gender Effects Benchmarked on Brazilian Old Economy Organizations

    Directory of Open Access Journals (Sweden)

    Marco Tulio Zanini

    2009-07-01

    Full Text Available It has been suggested that one of the negative aspects of the New Economy has been growing organizational survival-risk both at the firm and the sector levels. This precarious positioning of the firm has profoundly changed the work environment resulting in the dissolution of job-definition-boundaries, thereby raising the intensity of work and finally affecting the level and nature of trust in the workplace. This is the starting point for our study. Using a questionnaire developed by Gillespie, we investigated gender profiles concerning trust in Supervisors, Peers, and Team in the New and the Old Economies for Brazilian managers. The results show that, for the New Economy, Brazilian women are more willing to give trust to Supervisors whereas Brazilian men expressed higher levels of trust when dealing with Team members. The Peer results are mixed. For the Old Economy, men uniformly express higher levels of trust compared to women over all three reference groups. Finally, for gender matched comparisons, those working in the Brazilian Old Economy firms express higher levels of trust compared to their counterparts in the New Economy independent of gender or time worked. We conclude by discussing the control implications of the above results.

    Full Text Available With one of the most notable floras in the world for sustainable research, the Brazilian Amazon region currently counts on financial incentives from the Brazilian Government for private national and foreign businesses. The ongoing implantation of a Biocosmetics Research and Development Network (REDEBIO aims to stimulate research involving natural resources from the Brazilian states that make up the zone defined as “Amazônia Legal”. The objective of this region, still under development in Brazil, is principally to aggregate value to products manufactured in small local industries through the use of sustainable technology currently being established. Certain certified raw materials already included in the country’s sustainability program, have also begun to be cultivated according to the requirements of organic cultivation (Neves, 2009. The majority are species of Amazonian vegetation: Euterpe oleracea (Açai, Orbignya martiana (Babaçu, Theobroma grandi-florum (Cupuaçu, Carapas guianensis (Andiroba, Pentaclethra macroloba (Pracaxi, Copaifera landesdorffi (Copaiba, Platonia insignis (Bacuri, Theobroma cacao (Cacao, Virola surinamensis (Ucuuba and Bertholletia excelsa (Brazil nut. These generate phytopreparations, such as oils, extracts, and dyes that are widely used in the manufacture of Brazilian organic cosmetics with scientifically proven topical and capillary benefits. In the final balance, Brazilian organic cosmetics should continue to gain force over the next few years, especially with the regulation of the organic cosmetics market that is being drafted by the Brazilian Ministry of Agriculture. Moreover, lines of ecologically aware products that provide quality of life for both for rural and metropolitan communities show a tendency to occupy greater space in the market.

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

    Full Text Available OBJECTIVE: This study describes educational actions concerning organic foods conducted in Brazilian public schools and investigates how these actions are associated with the weekly workload and duration of employment of the dietician responsible for school meals. METHODS: In 2012 this cross-sectional, census-type study used an electronic questionnaire to collect data from dieticians or others responsible for school meals in all 5,565 Brazilian municipalities. The software Stata 11.0 was used for the statistical analyses. RESULTS: Although all Brazilian municipalities were contacted, 93.1% (n=5,184 replied. Of these, 94.2% had dieticians in charge of the school meals. Organic food-related educational actions were provided in the schools of 37.9% of the municipalities. The main actions were school gardening (67.1% and development of educational material (50.7%. Having a dietician responsible for school meals was not associated with the existence of educational actions at school (p=0.372. However, municipalities with dieticians in charge of school meals for at least twelve months were 22.0% and 20.0%, respectively, more likely to provide educational actions at school and include the subject 'organic foods' in the municipal school curriculum (p<0.05 for both. Dieticians' weekly work hours was directly related to the performance of school gardening-related activities (p=0.016. CONCLUSION: The percentage of Brazilian municipalities that provide organic food-related educational actions at school is low. Additionally, the availability of such actions relates to the dietician's duration of employment and weekly work hours.

  10. Persistent organic pollutants in liver of Brazilian sharpnose shark (Rhizoprionodon lalandii) from southeastern coast of Brazil.

    In the present study, persistent organic pollutants (POPs) were determined in 14 livers from specimens of the Brazilian sharpnose shark (Rhizoprionodon lalandii), which is an important economic resource for small-scale fisheries on the southeastern coast of Brazil. The following concentrations (lipid weight) of POPs were found: ∑PCBs: 1019±267 ng g(-1); ∑DDTs: 111±40 ng g(-1) and ∑PBDEs: 10.4±4.78. PCB 153 made the greatest contribution to ∑PCB (21.4%), followed by PCB 138 (14.6%) and PCB 180 (9.94%). Among chlorinated pesticides, only the p,p'-DDE and p,p'-DDD isomers had concentrations above the detection limit. Moreover, levels above the detection limit were found only for PBDE congeners 47 and 100 (BDEs 47>99). On average, BDE 47 accounted for 88% of the total PBDE load. The feeding habits of the Brazilian sharpnose shark close to the Brazilian coastline are likely the most important difference regarding the accumulation of POPs in comparison to oceanic species that feed in deeper waters. Thus, this species may be used to evaluate the pollution of coastal areas as well as human exposure to contaminants, as the Brazilian sharpnose shark is a frequently used for human consumption. Further studies in other areas of Brazil and involving other species are needed to clarify the mechanisms and potential impact of POPs, which can affect the biology of different organisms and cause population declines.

    Full Text Available The purpose of this study is to understand the impact of the new Brazilian legislation regulating partnerships between the State and Civil Society (Nonprofit Organizations between 1999 and 2002. The passing of Law No. 9790/99 – known as the Nonprofit Law – created the legal concept of Organizações da Sociedade Civil de Interesse Público – OSCIPs (Public Interest Civil Society Organizations. Based on an exploratory survey, this study, using the Institutional Theory, allowed the analysis of how older organizations (NGOs and traditional social benefit organizations resisted to the adoption of the OSCIP standard due to organizational inertia, while acceptance of the model was greater among younger organizations, in a clear coercive and normative isomorphic development.

    2007-09-01

    Full Text Available This paper examines the discourse configurations on the environmental theme in business organizations and its relevance to the understanding of the inclusion of ecological discourses in the discourses of organizational members. A case study into a Brazilian telecommunications company offers empirical evidence. It begins with the understanding that organizations adopt several strategies in an attempt to disseminate a certain environmental discourse. As these efforts share space with other pressures, a fragmented discourse emerges. In this paper, the pressures of the environmental theme on organizations are discussed in order to understand this process. The second part of the argument focuses on the context of the case study – Brazilian organizations – and, afterwards, the third part deals with ecological discourses in their insertions in organizational interests. The data of the case study were collected through documental research and 40 semi-structured interviews. The analysis was applied based on Discourse Analysis. In conclusion, an ambiguous discourse configuration was shown that offer elements for the understanding that philanthropy, legal obligation and organizational competitiveness need to be used together to offer legitimacy to the theme of environmental responsibility in business organizations.

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

    In this paper we present the results of the first phase of the project Who is Who in Brazilian Environmental Health. The aim of this project is to identify and characterize the Academic Groups and Civil Society Organizations acting on the field of environmental health that are able to contribute both to the strengthening of its technical and scientific basis, and to the dialogue with organized civil society. The identification took place through the data source available at CNPq (Research Groups Directory), ABONG (Brazilian Association of Non-Governmental Organizations), FBOMS (Brazilian Forum of NGOs and Social Movements for Environment and Sustainable Development) and RBJA (Brazilian Network for Environmental Justice). The results were presented and discussed based on time evolution, geographic distribution and areas of research and action. Final considerations point to the great potential for dialogue between experts and non experts, governmental and non-governmental, in order to create the foundation for a extended peer community capable of combining policies, knowledge, technologies and actions, seeking the comprehension and search of solutions to the establishment of health as a prerequisite and X a result of well being and full life.

    2003-02-01

    Full Text Available Soil organic matter from the surface horizon of two Brazilian soils (a Latosol and a Chernosol, in bulk samples (in situ SOM and in HF-treated samples (SOM, was characterized by elemental analyses, diffuse reflectance (DRIFT and transmission Fourier transform infrared spectroscopy (T-FTIR. Humic acids (HA, fulvic acids (FA and humin (HU isolated from the SOM were characterized additionally by ultraviolet-visible spectroscopy (UV-VIS. After sample oxidation and alkaline treatment, the DRIFT technique proved to be more informative for the detection of "in situ SOM" and of residual organic matter than T-FTIR. The higher hydrophobicity index (HI and H/C ratio obtained in the Chernosol samples indicate a stronger aliphatic character of the organic matter in this soil than the Latosol. In the latter, a pronounced HI decrease was observed after the removal of humic substances (HS. The weaker aliphatic character, the higher O/C ratio, and the T-FTIR spectrum obtained for the HU fraction in the Latosol suggest the occurrence of surface coordination of carboxylate ions. The Chernosol HU fraction was also oxygenated to a relatively high extent, but presented a stronger hydrophobic character in comparison with the Latosol HU. These differences in the chemical and functional group composition suggest a higher organic matter protection in the Latosol. After the HF treatment, decreases in the FA proportion and the A350/A550 ratio were observed. A possible loss of FA and condensation of organic molecules due to the highly acid medium should not be neglected.

  1. Brazilian Solidarity Economy Rural Organizations: Validating Performance Evaluation Criteria Based on Decision Makers’ Perception

    Directory of Open Access Journals (Sweden)

    Leomara Battisti Telles

    2017-06-01

    Full Text Available The majority of the world’s current economic models are destructive and unsustainable. Little progress has been made in recent years to change this, despite significant discussion surrounding the theme. In this context, the solidarity economy presents itself as an alternative that seeks environmental and economic sustainability, as well as social promotion. In Brazil, Solidarity Economy Rural Organizations (SEROs began in the 1970s. As with organizations from other sectors, they should be evaluated in relation to their ability to achieve social and solidarity objectives. Thus, this study aims to present a theoretical model of performance evaluation indicators for Solidarity Economy Rural Organizations in Southern Brazil based on the perceptions of the organizations’ decision makers. SERO representatives interviewed were asked to rank 36 criteria commonly used in performance evaluations, which were grouped into six dimensions: (1 legal documents and standards; (2 valuing of human work; (3 technology and economy; (4 acknowledgment of women; (5 preservation of and respect for nature; and (6 cooperation and solidarity. The results show that SERO representatives consider that performance evaluations should adhere to the Brazilian Declaration of Solidarity Economy Principles. Additionally, we identified a greater concern with criteria correlated to technical and legal aspects than criteria related to solidarity and humanitarianism. These results are relevant for the maintenance of rural solidarity economy organization as they provide a base for developing processes and tools to be used in SERO performance evaluations; such processes are necessary to maintain sustainable development in low-income economies, and to enable solidarity organizations to reach their objectives.

The objective of this study was to evaluate the total organic carbon (TOC and nitrogen (TN contents in different fractions of the soil organic matter (SOM of an Oxisol of the Brazilian semiarid region under different irrigated crops and different soil management systems. Seven treatments were evaluated, which consisted of two soil management systems (no - till and conventional tillage and three crops (maize, sunflower and sorghum, using as reference the soil under a native forest (NF. The summer crops preceded common bean crops in the autumn - winter. The total organic carbon content, total nitrogen, carbon content in humic substances and their constituents (fulvic acids, humic acids and humin and labile, non - labile and water - soluble carbon contents were evaluated two years and three months after the experiment implementation to determine the carbon lability (L lability index (LI, partitioning index (CPI and management index (CMI. The greatest carbon, nitrogen and organic matter contents in the soil surface layer (0.00 - 0.05 m were found in crops under no - till system (NTS, especially maize. The crops under NTS presented greater carbon content in humic substances than the conventional tillage system (CTS ones in the layer 0.05 - 0.10 m. The crops under NTS presented greater sustainability in the Brazilian semiarid region compared with those under CTS, as shown by their higher CMI in the soil surface layer.

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

    This study aims to identify and analyze strategies by civil society organizations working with breast cancer (CSOs) on access to drugs in Brazilian Unified National Health System (SUS) and the main social actors. A qualitative approach used the snowball technique, semi-structured interviews, and participant observation. Thematic analysis was based on the following categories: access to drugs for breast cancer treatment, relationship between CSOs and government, relationship between CSOs and the pharmaceutical industry, and other strategies used by CSOs. The results showed that civil society organizations have influenced access to drugs for breast cancer in the SUS and that their main strategies have focused on pressuring government at all levels. Meanwhile, the pharmaceutical industry sponsors some CSOs in order to strengthen them and expand its own market. The main difficulties in access to such drugs involve insufficient services, unequal treatment, and inclusion of technology in the SUS.

We conducted in-depth interviews with 8 of the first co-op members, who reported a reduction in symptoms associated with the use of traditional cleaning agents and a new sense of mutual support. Critical to the co-op's success have been the supportive roles of its academic partners (Tufts University and the University of Massachusetts, Lowell), effective media outreach, and a focus on advancing social justice. Next steps include implementing a formal business plan and assessing the appropriateness of cooperatives in other industries.

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

    Full Text Available Strategic change has been a subject in evidence in organizational studies. In recent years, the concept of strategy has evolved from a purely static to a more dynamic point of view, renewing the research agenda on this subject. Thus, this article aims to analyze the strategic change that occurred in a state-owned Brazilian Electric Sector (SEB, using for that, the theory of coevolution as a conceptual framework. Most research about processes of change focuses on private organizations. Therefore, the analysis of strategic change in a state-owned company reveals peculiarities that are not usually addressed in the literature. Furthermore, the theory of coevolution, unlike other theories of analysis, adopts an integrated view on the issue of adaptation of organizations in relation to their environment, thus broadening the understanding of the phenomenon of strategic change. The research was characterized as a case study descriptive and longitudinal. Data were collected through semi-structured interviews, direct observation and document analysis. The results showed that the change in the company occurred in a coevolutionary process involving the competitive dynamics of the sector and institutional system in which organizations and industries interact with each other. The theory of coevolution demonstrated its potential to show results that would normally be withheld if it was adopted a narrower perspective of analysis.

    Full Text Available Abstract Chagas' disease is a parasitic infection caused by protozoan Trypanosoma cruzi that affect millions of people worldwide. The available drugs for treatment of this infection cause serious side effects and have variable efficacy, especially in the chronic phase of the disease. In this context, natural compounds have shown great potential for the discovery of new chemotherapies for the treatment of this infection and various other diseases. In present study, we evaluated the in vitro antiprotozoal activity of five species of Brazilian and Spanish marine sponges (Condrosia reniformes, Tethya rubra, Tethya ignis, Mycale angulosa and Dysidea avara against T. cruzi. By GC–MS data, we observed that in these extracts were present the major classes of the following compounds: hydrocarbons, terpenes, steroids and alcohols. The extracts showed activity against the three forms of this parasite and did not induce toxicity in mammalian cells. Better activities were observed with the extracts of marine sponges, C. reniformes (EC50 = 0.6 μg/ml, D. avara (EC50 = 1.1 μg/ml and M. angulosa (EC50 = 3.8 μg/ml, against trypomastigote forms. In intracellular amastigote forms, the extract of T. ignis showed IC50 of 7.2 μg/ml and SI of 24.65. On this basis, our results indicate that these extracts can be promising chemotherapeutic agents against T. cruzi.

    The implementation of quality control procedures in analytical laboratories around the world has become essential in order to ensure the quality and safety of food. This article describes the procedure adopted by the Brazilian government in order to achieve this goal, specifically in the area of analysis of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs). The validation of a multiresidue method, the calculation of measurement uncertainty, and the quality control procedure adopted in the determination of these compounds in beef cattle fat were performed as set out in national legislation (Brasil, 2011), which is aligned with international guidelines. Evaluation was made of selectivity, linearity, precision (repeatability and reproducibility), accuracy, and limits of detection and quantification. Stability studies were also undertaken. The technique was extended to three other matrices (poultry, horse, and pig adipose tissues), with evaluation of matrix effects, selectivity, linearity, and accuracy. The analyses were performed by gas chromatography with electron capture detection (GC-ECD) and mass spectrometric detection (GC-MS). In recent years, analyses conducted under the National Plan for Control of Residues and Contaminants (PNCRC) have shown no exceedances of the maximum permitted residue levels (MRLs) of pesticides and PCBs in these tissues, as observed in other countries that carry out effective monitoring of these contaminants.

    This work presents the first comprehensive organic characterization of atmospheric aerosols from an agro-industrial region (São Paulo State, Brazil) highly impacted by biomass burning. The organic speciation was performed using different solvents of increasing polarity, enabling the identification and quantification of 172 different organic species by GC-MS. The mass of organic compounds reached 123 μg m- 3 in an aerosol sample collected during the sugar cane harvest period compared with 0.82 μg m- 3 in the non-harvest period. The samples most impacted by biomass burning were those with the highest percentages of non-polar compounds (n-alkanes; up to 96%). However, in absolute terms, the total mass of polar compounds in such samples was greater than for samples less impacted by this activity. Retene (a marker for biomass combustion) was the most abundant of the 19 polycyclic aromatic hydrocarbons quantified, corresponding to 14%-84%. This work shows that biomass burning was responsible for a benzo(a)pyrene equivalent index value that exceeded the recommendation of the World Health Organization. Principal component analysis indicated that agricultural biomass burning and emissions from crop processing facilities explained 42% of the variance of the data, while 37% was explained by urban emissions, 10% by vehicle emissions, and 10% by biogenic sources. This study provides insights into the emissions of a suite of organic compounds that could participate in anthropic alteration of regional cloud formation and precipitation patterns.

    Full Text Available ABSTRACT Objective To describe the purchase of family farm and organic foods by the Brazilian School Food Program in the municipalities of the state of Santa Catarina, Brazil. Methods This is an analytic and descriptive study conducted from 2010 to 2011. An electronic survey was sent to all 293 Santa Catarina municipalities. The Chi-square test investigated the association between the study variables. Results Between 2010 and 2011, the number of municipalities that purchased family farm foods increased by 36%, with a total of 96% of Santa Catarina municipalities buying family farming foods in 2011. Of the 96%, 70% complied with Article 14 of Law nº 11,947/2009, which determines that at least 30% of the funds provided by the National Fund for the Development of Education should be spent on family farm products, and 48% purchased organic foods. The South was the state region that most complied with Article 14 (85%; p=0.02. However, as municipality size increased, compliance with Article 14 decreased (p=0.04. The municipalities that had the most difficulties buying family farm and organic foods were those with the lowest Municipal Human Development Index and number of students. Conclusion Most Santa Catarina municipalities purchased family farm foods in 2011, and most municipalities that complied with Article 14 of Law nº 11,947/2009 were in the South state region. Finally, municipalities with low Municipal Human Development Index and number of students had the most difficulties buying family farm foods.

    This study analyses the development of a tobacco-control agenda in Brazil following the country's participation in the World Health Organization Framework Convention on Tobacco Control (WHO-FCTC). This process started with the diplomatic negotiations for the participation of Brazil in the treaty, in 2003, and its ratification by the National Congress, in 2005, and was marked by substantial controversies between public health players, who are accountable for tobacco-control actions, and the high echelon of Brazilian diplomacy, emissaries of the tobacco industry, representatives of small tobacco farmers from the Southern region of the country, congress representatives, senators and ministers. The study is based on the contributions of John W. Kingdon on the development of an agenda for the formulation of public policies. It took into account secondary references, legislative and institutional sources from the 1995 to 2005 period. It concluded that the association of tobacco-related healthcare actions by technically skilled officials, the involvement of the high echelon of the Ministry of Foreign Affairs (policy flow), the initiative for the establishment of the WHO-FCTC (problem flow), and the existence of a favorable environment in both, executive and legislative (political flow), opened a window of opportunity for WHO-FCTC ratification and its inclusion in the government decision agenda.

    Sugarcane cultivation is associated with catchment-wide impacts related to application of vinasse, a nutrient-dense effluent with high eutrophication potential. We evaluated the potential for biochar (charcoal produced from pyrolyzed filtercake) to mitigate carbon and nutrient leaching in a cultivated Brazilian Ferralsol after vinasse application. Twelve soil columns (soil alone [S], soil with vinasse [SV], soil with vinasse and biochar [SVB], and soil with biochar [SB]) were flushed with water and then treated with water or vinasse. Samples collected via vacuum filtration were examined via UV-Vis and fluorescence spectroscopy. Biochar attenuated dissolved organic carbon (DOC) leaching in soil (S vs. SB) as well as in relation to vinasse application (SV vs. SVB). Biochar-amended soil preferentially retained high-molecular weight, humic-like DOC species, as revealed by fluorescence spectroscopy and optical indices, but did not retain low-weight amino acid-like species. Vinasse application also increased total NO3(-) flux, which may have been exacerbated by biochar co-application. Vinasse treatment strongly affects carbon and NO3(-) fluxes in this tropical soil. Biochar attenuated DOC leaching, likely through stabilization of complex compounds already present in soil, but did not lessen NO3(-) fluxes. Thus, biochar amendments in vinasse application areas may decrease carbon leaching. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available This work analyses the use of the discourse as a strategy for the dissemination of new cultural values in a State Secretary beginning in 1995. For this purpose, discourse analysis was used according to the concept by Fiorin (1997 based on the concepts of figures, themes and ways to manipulate discourses. It is a descriptive and exploratory study. The theoretical discussion was based on the concept of organizational culture in the dimensions of artifacts and cultural values. The analysis was carried out from the documents of the organization, including the projects of modernization, plans of action, reports of strategic planning, laws and decrees. Furthermore, the official journal of the organization from 1998 to 2006 was analyzed. For the years 2007 and 2009, the analysis was conducted based on the organization’s website. The results show that there was deep concern with regard to the theme of organizational culture during the whole process of modernization. They also indicate that the organization used different discourse resources to guide the individual behavior of its members such as seduction, temptation, intimidation and provocation. They also show that the official discourses are not in harmony with the various discourses found in the organization due to the plurality of values that are shared by the organizational actors.

    The concentration and biomarker compositions of sedimentary organic matter (OM) as well as fine and coarse suspended particles were analysed to identify the impact of deforestation on the transport of terrigenous organic matter (OM) in the Rio Tapajos, a major tributary to the Amazon. Substantial shifts in the concentration and composition of recently deposited sedimentary OM suggest that intensive deforestation over the last few decades has considerably modified the natural inputs of sedimentary materials to the aquatic ecosystems by disrupting the terrigenous fluxes of humus and soil and materials from the drainage basin. The observed compositional changes of bulk OM and land derived biomarkers (e.g. lignin) in recent sediments illustrate a sedimentary enrichment in OM from soil horizons that, under normal forest cover, tend to be retained in the drainage basin. On average, the recently accumulated OM is nitrogen-rich ((C/N)a=12-15) and more highly degraded ((Ac/Al)v=0.4-0.6 and DHBA/V=0.15-0.20) than deep materials ((C/N)a=20-30, (Ac/Al)v=0.25-0.4, and DHBA/V=0.05-0.10), showing that this recently accumulated material is more humified than original inputs to the aquatic system, and consistent with increased exportation if fine eroded mineral and organic particles from surface soils along river banks. The present study illustrates the relevance of using OM oxidation products in sediment profiles to evaluate deforestation impacts on aquatic ecosystems and to characterize the nature of eroded soil materials, complementing studies on mineral/metal cycling.

    During 2009-2012, wild animals were sampled in the Amazon biome of Brazil. Animal tissues and blood were tested by polymerase chain reaction (PCR) assays targeting DNA of the bacterial family Anaplasmataceae (genera Anaplasma, Ehrlichia, Wolbachia) and the genus Borrelia. Overall, 181 wild animals comprising 36 different species (2 reptiles, 5 birds, and 29 mammals) were sampled. All birds and reptiles were negative by all PCR assays, as well as all mammals for the Borrelia PCR assay. Anaplasmataceae agents were searched by PCR assays targeting two different genes, the ribosomal 16S rRNA gene and the protein-coding dsb gene. Three dsb closely related haplotypes were generated from 3 white-lipped peccaries (Tayassu pecari). In a phylogenetic analysis inferred from dsb partial sequences, these haplotypes grouped with previously reported Ehrlichia haplotypes from jaguar (Panthera onca) and horse from Brazil, suggesting that they could all represent a single species, yet to be properly characterized. A unique dsb haplotype was generated from a sloth (Bradypus tridactylus), and could also represent a different Ehrlichia species. All these dsb haplotypes formed a clade sister to the Ehrlichia ruminantium clade. Three distinct 16S rRNA gene haplotypes were generated from a wild guinea pig (Cavia sp.), a woolly mouse opossum (Micoureus demerarae), and two from robust capuchin monkeys (Sapajus sp.). In a phylogenetic analysis inferred from 16S rRNA gene partial sequence, these haplotypes grouped within the Wolbachia clade, and are likely to represent Wolbachia organisms that were infecting invertebrate metazoarians (e.g., filarids) associated with the sampled mammals. Two deer (Mazama americana) samples yielded two distinct 16S rRNA gene sequences, one identical to several sequences of Anaplasma bovis, and an unique sequence that grouped in a clade with different Anaplasma species. Our results indicate that a variety of genetically distinct Anaplasmataceae organisms

    2017-03-01

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

    The marine cyanobacterium Trichodesmium occur in tropical and subtropical oceans and contribute significantly to the nitrogen and carbon cycle. Although their occurrence is broadly reported, just a few are located in southern Atlantic Ocean. This work aimed to collect and identify the species near south-southeastern Brazilian shelf slope during two consecutive autumns (June/2013 and May/2014)(Figure 01). We observed their vertical distribution, unique strategies for nutrient acquisition and identified other microplanktonic groups co-occurring. Overall, Trichodesmium trichomes were more abundant at surface (> 50 m), under lower wind speed ( 157,000 trichomes L-¹) were located at the northernmost stations. The study area had low concentrations of phosphate (nutrient regions were observed, some of them in association with nitrogen-fixers as Ornithocercus spp. (in association with picocyanobacteria), and Rhizosolenia spp. (in association with Richelia intracellularis)(Figure 01). In contrast, by the use of scanning electron microscopy coupled with EDS X-ray, we could observe particles that were concentrated inside the colonies of Trichodesmium. The analysis of the content revealed a potential source of elements for the organism, since we found high concentrations of iron (10-20% of the total composition), phosphorus and zinc. Some colonies, moreover, seemed to be influenced by the La Plata River sediments due to the presence of titanium. Also, the trichomes were in association with heterotroph bacteria that could be involved in dissolution processes, increasing the availability of essential nutrients.

The main contributions of microplanktonic species are represented as sectors of pie charts, except when Trichodesmium spp. contributed to > 90% to total amount of microplankton assemblages.

    Full Text Available Stress is a generic term that summarizes how psychosocial and environmental factors influence physical and mental well-being. The interaction between stress and immunity has been widely investigated, involving the neuroendocrine system and several organs. Assays using natural products in stress models deserve further investigation. Propolis immunomodulatory action has been mentioned and it has been the subject of scientific investigation in our laboratory. The aim of this study was to evaluate if and how propolis activated macrophages in BALB/c mice submitted to immobilization stress, as well as the histopathological analysis of the thymus, bone marrow, spleen and adrenal glands. Stressed mice showed a higher hydrogen peroxide (H2O2 generation by peritoneal macrophages, and propolis treatment potentiated H2O2 generation and inhibited nitric oxide (NO production by these cells. Histopathological analysis showed no alterations in the thymus, bone marrow and adrenal glands, but increased germinal centers in the spleen. Propolis treatment counteracted the alterations found in the spleen of stressed mice. New research is being carried out in order to elucidate propolis immunomodulatory action during stress.

    During 2009-2012, wild animals were sampled in two areas within the Amazon biome of Brazil, in the states of Mato Grosso and Pará. Animal tissues and blood were molecularly tested for the presence of Piroplasmida (genera Babesia, Theileria, Cytauxzoon) or Hepatozoon DNA. Overall, 181 wild animals comprising 36 different species (2 reptiles, 5 birds, and 29 mammals) were sampled. The following Piroplasmida agents were detected: Cytauxzoon felis in one ocelot (Leopardus pardalis), Theileria cervi in two red brocket deer (Mazama americana), Theileria spp. in three nine-banded-armadillos (Dasypus novemcinctus), one agouti (Dasyprocta sp.), and four lowland pacas (Cuniculus paca), Babesia spp. in one common opossum (Didelphis marsupialis) and one white-lipped peccary (Tayassu pecari). The following Hepatozoon agents were detected: Hepatozoon sp. (possibly Hepatozoon caimani) in three spectacled caimans (Caiman crocodilus), Hepatozoon felis in an ocelot (Leopardus pardalis), and Hepatozoon spp. in one scorpion mud turtle (Kinosternon scorpioides) and one lowland paca (Cuniculus paca). Phylogenetic analyses inferred by the 18S rRNA gene partial sequences supported these results, highlighting at least five novel Piroplasmida agents, and two novel Hepatozoon agents. This study screened the presence of tick-borne protozoa in a number of wildlife species from the Amazon for the first time. Our results indicate that a variety of genetically distinct Piroplasmida and Hepatozoon organisms circulate under natural conditions in the Amazonian wildlife.

    Bacteremia is one of the most frequent and challenging hospital-acquired infection and it is associated with high attributable morbidity and mortality and additional use of healthcare resources. The objective of this work was to determine the frequencies of its occurrence, organisms and resistance phenotypes associated to nosocomial acquired bloodstream infections. A total number of 51 nosocomial bacteremia by Gram-negative and 99 by Gram-positive were evaluated and compared during a 15-month period.

    The region known as Campos de Cima da Serra, located at 800 to 1400 m above sea level in the northeas of Rio Grande do Sul State, Brazil, is covered by a mosaic of natural grassland and Araucaria forest. Cattle raising, introduced by the first European settlers about 200 years ago, is the traditional economic activity in the region, occurring extensively and continuously on the natural pasture. In the last 30 years, while seeking for higher profits, local farmers have introduced agricultural crops and Pinus Taeda plantations in the original pasture lands. Pinus plantations are established in this area as dense monocultures and not as a sylvipastoral system, representing, thus, a severe threaten to the Campos' biodiversity. The soils are shallow, though very acidic (pH 4.2) and rich in exchangeable Al (28 to 47% of Al saturation), and present high contents of SOM in the surface layer (in general, higher than 4 %), which shows a low decomposition degree, as indicated by its high proportion of C-O alkyl groups (51 to 59 %). Considering that the biome sustainability of this region is being progressively affected by the change of land use and that systematic studies about exotic trees afforestation in that region are very scarce, our main objective was to investigate the impact of the introduction of Pinus on the SOM composition and chemical attributes of highland soils in 8 (Pi8) and 30 (Pi30) years old plantations, using as reference the original condition under native pasture (NP). In each studied Leptosol, soil samples were collected from three layers down to 15 cm ( 0-5 cm, 5-10 cm and 10-15 cm). Contents of exchangeable cations and of micronutrients and soil pH were determined. The SOM composition was investigated by means of elemental analyses, FTIR and fluorescence spectroscopy (three replicates). Prior to the spectroscopic analyses, samples were demineralized with 10% HF solution and organic matter loss was monitored. From the FTIR spectra, an aromaticity index

The most promising antimicrobial results for cell wall bacteria were obtained by extracts from seaweeds Laurencia dendroidea and Sargassum vulgare var. nanun (MIC 250 μg/ml, and by the bryozoan Bugula neritina (MIC 62.5 μg/ml, both against Staphylococcus aureus. As for antimollicutes, extracts from seaweeds showed results better than the extracts from invertebrates. Almost all seaweeds assayed (92% exhibited some antimicrobial activity against mollicutes strains (Mycoplasma hominis,Mycoplasma genitalium,Mycoplasma capricolum and Mycoplasma pneumoniae strain FH. From these seaweeds, A1 (Canistrocarpus cervicornis, A11 (Gracilaria sp. and A4 (Lobophora variegata showed the best results for M. pneumoniae strain FH (MIC 250 μg/ml. Furthermore, compounds 1 and 2 were also assayed against mollicutes strains M. hominis,M. genitalium,M. capricolum,M. pneumoniae strain 129 and M. pneumoniae strain FH, which showed MIC > 100 μg/ml. Antioxidant activities of extracts from these marine organisms were inactive, except for E7 (from sponge Ircinia sp., which exhibited moderated antioxidant activities for two methods assayed (IC50 83.0 ± 0.1 μg/ml, and 52.0 ± 0.8 mg AA/g, respectively. Finally, for the anticholinesterase activity, all the 29 samples evaluated (100% exhibited some level of activity, with IC50 < 1000 μg/ml. From these, seaweeds extracts were considered more promising than marine invertebrate extracts [A10 (IC50 14.4 ± 0.1 μg/ml, A16 (IC50 16.4 ± 0.4 μg/ml and A8 (IC50 14.9 ± 0.5 μg/ml].

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

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

    Full Text Available This study aimed to analyze the resistance factors to change the Management Information System - MIS, in an organization of the Brazilian judiciary, describing how the actions of the actors can inhibit the institutionalization of management control practices. We use the case study method, with the framework of Burns and Scapens (2000 to understand the process in which the rules become habits and routines and are institutionalized. Huy’s framework (2001 were used to explain how the ideal types of planned change to analyzing can explain resistance factors. The cut chosen for analysis was the IT structures and processes recommended by law and supported by the literature in the field. We conducted interviews, document analysis and field notes for the collection and discourse analysis elements - DA for data analysis. The results indicate that the structures and processes IT should form the MIS of organization are not fully institutionalized, although the coercive pressure to change. Thus, we observe a purely ceremonial use of various processes of MIS and concluded that if senior management does not exercise its coordinating role and support the process of change and if there is no proper training of servers, hardly the rules become will habits and patterns, or they will be institutionalized. The study contributes to the field to describe how failures in planning the change and / or the lack of interest of senior management, coupled with the lack of training of staff inhibits the institutionalization of new rules, even when these are established coercively.

    The organ shortage for transplantation, the principal factor that increases waiting lists, has become a serious public health problem. In this scenario, the intensivist occupies a prominent position as one of the professionals that first has a chance to identify brain death and to be responsible for the maintenance of the potential deceased donor. This report attempts to establish guidelines for care and maintenance of adult deceased donor organs guiding and standardizing care provided to patients with brain death. These guidelines were composed by intensivists, transplant coordinators, professionals from various transplant teams, and used transplant center. The formulated questions were forwarded to all members and recommendations were constructed after an extensive literature review selecting articles with the highest degree of evidence. Guidelines were developed in the form of questions reflecting frequent experiences in clinical intensive care practices. The main questions were: Is there an optimal interval for keeping organs of deceased donors viable? What actions are considered essential for maintaining deceased donors in this period? What are the limits of body temperature? How should the patient be warmed? Which laboratory tests should be performed? What is the collection interval? What are the limits in the laboratory and the capture scenario? What are the limits of blood pressure? When and how should one use catecholamines? This pioneer project involved a multidisciplinary team working in organ transplantation seeking to provide treatment guidance to increase the number of viable organs from deceased adult donors.

    Full Text Available This work makes an analysis of the determinants of Corporate Social Responsibility (CSR of Brazilian firms, as proxied by firm membership of the ISE Index of BM&FBOVESPA. Besides other proposed determinants of CSR present in the literature (firm size, profitability, growth opportunities, the work examines ownership concentration and the persistence on CSR status. Logit regression estimates have been run for a sample of 1649 firm-year observations in the period 2006-2011. The findings show that CSR of Brazilian firms is inversely correlated to its ownership concentration indicating that controlling voting shareholders may not see social concerns as a priority. Besides, firms tend to maintain their present CSR status. The results also indicate that leading CSR firms are larger, face more growth opportunities, and are persistent in their superior CSR situation.

    Full Text Available Soil aggregation and carbon distribution are important indicators of soil quality. Moreover, these attributes are closely related to CO2 fluxes in the soil-atmosphere interface. We sought to evaluate soil aggregation, organic carbon distribution and CO2 evolution in different land uses of Minas Gerais Triangle. Four different land uses were selected: (1 Panicum maximum, (2 Panicum maximum Jacqvr. (Tanzânia, (3 sugarcane, and (4 native Cerrado (control. In each land-use type, soil samples from a 0-10 cm layer were collected. The samples were air-dried and sieved in order to obtain aggregates sized 4-2 mm. The samples were submitted to wet-sieving to evaluate stability and also to obtain aggregates of different sizes: 4-2 mm; 2-1 mm; 1-0.5 mm; and 0.5-0.25 mm. Total organic carbon, humic substances and texture were determined for each aggregate size fraction. The CO2 emission was measured in field and lab conditions, both by the capture in NaOH solution method. The native Cerrado and Panicum maximum Jacqvr. (Tanzânia areas (mostly clay showed the highest soil aggregation. The conventional soil tillage adopted in sugarcane areas contributed significantly to aggregate disruption. In all of the areas, the largest aggregates had higher organic carbon and humic substances. Organic carbon content and soil texture seem to be closely associated with CO2 emissions in the areas studied.

    Full Text Available Freshwater lagoons comprise important coastal ecosystems and natural buffers between urbanized land areas and open ocean in the Rio de Janeiro State, Brazil. Studies of sediment and water chemistry, zooplankton and bacterial communities to assess the extent of anthropogenic disturbance are available. Here we contribute with an organic-geochemical approach supplemented by some microbiological aspects to complete the characterization of these lagoonal ecosystems. Bulk organic matter and extractable lipids (aliphatic hydrocarbons, alcohols and fatty acids, sterols were investigated from two locations per lagoon: at the seaward site and landward ends - and at two depth intervals (0-3 and 3-6 cm per site. Urbanized Imboacica Lagoon received increased anthropogenic input over the most recent years represented by the topmost 3 cm of sediment, whereas deeper sediment layers are less affected by human influence. Eutrophication or nutrient availability favored enhanced algal/cyanobacterial growth. In remote Cabiúnas and Comprida Lagoons pristine conditions are preserved. Organic matter from vascular plants dominates (chain length of free lipids up to C36, which is exceptionally well preserved by acidic lagoonal waters. Differentiation between landward and seaward sites in these two lagoons is less well established due to much smaller surface/volume to catchment ratios. No anthropogenic influences are yet detectable in sediments of Cabiúnas and Comprida Lagoons.

  5. Organic Carbon and Physical Properties in Sandy Soil after Conversion from Degraded Pasture to Eucalyptus in the Brazilian Cerrado

    Directory of Open Access Journals (Sweden)

    Karla Nascimento Sena

    Full Text Available ABSTRACT Soil is currently seen as the most relevant carbon sink and the most effective carbon stabilizer. In contrast, agriculture is the second largest C emitter, after burning of fossil fuels. This organic carbon (OC introduced into the soil, mainly via organic matter (OM, is essential for several soil properties and plays an extremely important role in sandy soils. The objective of this study was to describe the changes in the amounts and pools of OC and the influence thereof on some physical soil properties in areas converted from pasture to eucalyptus. The following areas were analyzed: a degraded pasture (PAST, two areas of pasture-eucalyptus conversion after 2 and 15 years (EU02 and EU15, respectively and a preserved Cerrado area (CER in the east of the state of Mato Grosso do Sul. Soil samples were taken from the 0.00-0.05, 0.05-0.10, and 0.10-0.30 m layers. The OC was measured and analyzed, the carbon pool (CP calculated, aggregate stability, bulk density (BD, and macro- and microporosity determined, and total porosity (TP calculated to analyze the influence of land use on soil properties. The experimental design was completely randomized, and four clusters per area were established, with nine subsampling points, for a total of 36 subsamples per area, organized in 20 × 20 m grids, The soil under natural vegetation (preserved Cerrado was used as a control. The change from CER to commercial cultivation accelerates the process of OC loss (reductions of 25-35 % and reductions in soil physical quality. In the PAST area, OC was reduced by 30 % in the 0.00-0.05 m layer. Cumulative OC and CP were highest in the 0.00-0.05 m layer and decreased in the deeper layers in all land use treatments. Organic C in the 0.10-0.30 m layer was not influenced by land use, indicating the possibility of OC persistence in the soil for longer periods. Macroporosity and total porosity may be considered appropriate in CER and EU15, whereas the conditions for plant

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

    Full Text Available The purpose of this paper was to carry out an anatomical and histochemical analysis of the vegetative organs of Cissus verticillata (L. Nicolson & C.E. Jarvis, Vitaceae, to contribute for the attest the taxonomic identity of the medicinal plant. Samples from root, stem, leaf and tendril were cleared, dissociated and processed according to the usual methodology for observation under light and scanning electron microscopes. Histochemical tests were performed in order to identify polysaccharides, phenolic and lipid compounds. The C. verticillata root is typically protostelic, and the stem is eustelic with collateral bundles. The tendril presents structural organization similar to the stem, suggesting a common origin for both. The petiole has an epidermis with ornamented cuticle; the cortex is composed of collenchyma and parenchyma, and the vascular tissues are arranged in collateral bundles. The leaf blade is amphistomatic with non-glandular and glandular trichomes, and the mesophyll is dorsiventral. The identification of the idioblasts as secretion site of the phenolic compounds, mucilage and terpenoids as being responsible for the potential activity of the plant is of fundamental importance for future bioprospecting research on this species.

    Conclusions based on studies of the impacts of soil organic carbon (SOC) fractions and soil texture on macroaggregation and SOC stabilization in long-term (>20years) no-till (NT) fields remain debatable. This study was based on the hypothesis that the amount and frequency of biomass-C input associated with NT can be a pathway to formation of macroaggregates and to SOC buildup. The objectives were to: 1) assess the macroaggregate distribution (proportional mass, class mass) and the SOC and particulate organic carbon (POC) stocks of extra-large (8-19mm), large (2-8mm) and small (0.25-2mm) macroaggregate size classes managed for two decades by NT, and 2) assess the recovery of SOC stocks in extra-large macroaggregates compared to adjacent native vegetation (Andropogon sp., Aristida sp., Paspalum sp., and Panicum sp.). The crop rotation systems were: soybean (Glycine max L.), maize (Zea mays L.) and beans (Phaseolus vulgaris L.) in summer; and black oat (Avena strigosa Schreb), white oat (Avena sativa), vetch (Vicia sativa L.), black oat.+vetch (Avena strigosa Schreb+vetch) and wheat (Triticum aestivum L.) in winter. The experimental was laid out as 2×2 randomized block factorial with 12 replicates of a NT experiment established in 1997 on two highly weathered Oxisols. The factors comprised of: (a) two soil textural types: clay loam and sandy clay, and (b) two sampling depths: 0-5 and 5-20cm. The three classes of macroaggregates were obtained by wet sieving, and the SOC content was determined by the dry combustion method. The extra-large macroaggregate classes in 0-20cm depth for sandy clay (SdC) and clay loam (CL) Oxisol represented 75.2 and 72.4% of proportional mass, respectively. The SOC and POC stocks among macroaggregate classes in 0-5 and 5-20cm depths decreased in the order: 8-19mm>2-8mm ≈ 0.25-2mm. The SdC plots under soybean/maize at 3:1 ratio recovered 58.3%, while those at 1:1 ratio (high maize frequency) in CL recovered 73.1% of SOC stock in the extra

  10. On the accumulation of organic matter on the southeastern Brazilian continental shelf: a case study based on a sediment core from the shelf off Rio de Janeiro

    Renato da Silva Carreira

    2012-03-01

    Full Text Available Sterol and fatty acid biomarkers and isotopic composition (δ13C and δ15N of bulk organic matter (OM were quantified in a sediment core to characterize the accumulation of autochthonous OM in an area on the continental shelf adjacent to Rio de Janeiro State. In the sediment surface (0-1 cm the concentration of total sterols and fatty acids was at least one order of magnitude higher than that measured deeper down in the core and was dominated by labile and planktonic-derived biomarker compounds. These results suggest, as is confirmed by multivariate statistical analysis, the occurrence of an event of enhanced primary production in the water column and efficient export of particles to the bottom. Similar conditions have been observed at Cabo Frio, located 150 km to the north of our study site, during an upwelling event, suggesting that such events may exert a regional influence on primary production on the south-eastern Brazilian continental shelf. Beyond the signatures from this event, the presence of biomarker compounds from vascular plants suggests the additional influence of an outflow from Guanabara Bay at the study site. These results point to the need for further investigation of the relative influence of physical forcings and continental inputs on the biogeochemical processes on the section of the continental shelf considered in the present study.Marcadores moleculares na classe de lipídios (esterois, ácidos graxos e hidrocarbonetos e a composição isotópica (δ13C e δ15N da matéria orgânica bruta foram quantificados em amostras de um testemunho de sedimento para caracterizar o histórico recente de sedimentação da matéria orgânica na plataforma continental adjacente à Baía de Guanabara, no Estado do Rio de Janeiro.

    Full Text Available Significant progress has been obtained since the Second Brazilian Consensus Conference on Helicobacter pylori Infection held in 2004, in São Paulo, SP, Brazil, and justify a third meeting to establish updated guidelines on the current management of H. pylori infection. The Third Brazilian Consensus Conference on H pylori Infection was organized by the Brazilian Nucleus for the Study of Helicobacter, a Department of the Brazilian Federation of Gastroenterology and took place on April 12-15, 2011, in Bento Gonçalves, RS, Brazil. Thirty-one delegates coming from the five Brazilian regions and one international guest, including gastroenterologists, pathologists, epidemiologists, and pediatricians undertook the meeting. The participants were allocated in one of the five main topics of the meeting: H pylori, functional dyspepsia and diagnosis; H pylori and gastric cancer; H pylori and other associated disorders; H pylori treatment and retreatment; and, epidemiology of H pylori infection in Brazil. The results of each subgroup were submitted to a final consensus voting to all participants. Relevant data were presented, and the quality of evidence, strength of recommendation, and level of consensus were graded. Seventy per cent and more votes were considered as acceptance for the final statement. This article presents the main recommendations and conclusions to guide Brazilian doctors involved in the management of H pylori infection.

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

    In spite of the fact that pharmaceutical services are an essential component of all malaria programmes, quality of these services has been little explored in the literature. This study presents the first results of the application of an evaluation model of pharmaceutical services in high-risk municipalities of the Amazon region, focusing on indicators regarding organization of services and prescribing according to national guidelines. A theoretical framework of pharmaceutical services for non-complicated malaria was built based on the Rapid Evaluation Method (WHO). The framework included organization of services and prescribing, among other activities. The study was carried out in 15 primary health facilities in six high-risk municipalities of the Brazilian Amazon. Malaria individuals ≥ 15 years old were approached and data was collected using specific instruments. Data was checked by independent reviewers and fed to a data bank through double-entry. Descriptive variables were analyzed. A copy of the official treatment guideline was found in 80% of the facilities; 67% presented an environment for receiving and prescribing patients. Re-supply of stocks followed a different timeline; no facilities adhered to forecasting methods for stock management. No shortages or expired anti-malarials were observed, but overstock was a common finding. On 86.7% of facilities, the average of good storage practices was 48%. Time between diagnosis and treatment was zero days. Of 601 patients interviewed, 453 were diagnosed for Plasmodium vivax; of these, 99.3% received indications for the first-line scheme. Different therapeutic schemes were given to Plasmodium falciparum patients. Twenty-eight (4.6%) out of 601 were prescribed regimens not listed in the national guideline. Only 5.7% individuals received a prescription or a written instruction of any kind. The results show that while diagnostic procedure is well established and functioning in the Brazilian malaria programme

    Soil organic matter is the main sorptive soil compartment for atrazine in soils, followed in a minor scale by the inorganic fraction. In this study, the soil organic matter quality and atrazine sorption were investigated in four different soil types. The pedogenic environment affected the humification and therefore the chemical composition of the organic matter. The organic matter contribution to atrazine sorption was larger (60-83%) than that of the inorganic fraction. The organic matter capacity in retaining the herbicide was favoured by a higher decomposition degree and a smaller carboxylic substitution of the aliphatic chains. (author)

    Full Text Available Abstract The main aim of this study was to verify possible differences between a friendly pre-season match (FM and an official in-season match (OM regarding physical, technical, and organizational performances of a professional Brazilian futsal team. Ten professional futsal athletes participated in this study. The matches were monitored with video cameras (30 Hz and athlete trajectories obtained with automatic tracking. The values obtained for distance covered per minute, percentage of distance covered at moderate intensity, team coverage area, spread, passes, possessions, ball touches and successful passes per minute were greater for the OM than FM. On the contrary, percentage of distance covered, standing and walking was greater for the FM than OM. We concluded that physical, technical, and tactical performances are different between a FM and an OM in futsal and also these parameters mutually influenced each other distinctly. Future studies should verify whether pre-season tournaments reproduce similar demands to a regular season official match.

    Several techniques have been used to minimize the problems caused by the wax deposition, and the continuous addition of polymeric inhibitors is considered an attractive technological alternative. The addition of copolymers like polyacrylates, polymethacrylates or poly(ethylene-co-vinyl acetate) (EVA) permit to inhibit the deposition phenomenon; nonetheless, this effect is specific, i.e. similar copolymers present different performance depending on their physical-chemical properties in solution. In this work, the influence of the EVA vinyl acetate content on the viscosity and the pour point of a Brazilian crude oil were evaluated. A correlation between both results was also obtained. The phase behavior and the solubility parameter of EVA copolymers, with different vinyl acetate contents, were investigated in various solvents together with an evaluation of the efficiency of these copolymers as pour point depressants for two different samples of crude oil. EVA copolymers containing 20, 30, 40 and 80 wt.% of vinyl acetate were used and tests with the crude oil were carried out using 50, 500, 1000 and 5000 ppm of EVA as additive. The results obtained from viscosity measurements showed that only below the temperature at which wax crystals start forming did the copolymer exhibit a strong influence in the reduction of oil viscosity, at an optimum concentration. The pour point results revealed EVA 30 to be the most efficient. The results obtained from both experiments showed that the viscosity and the pour point behaviors do not show good correlation. Not only the solubility parameter and the vinyl acetate content, but also the molecular weight and polydispersity have an important influence on both phase behavior and pour point depression. Furthermore, it was confirmed that the additive must present a reduced solubility at a temperature close to the crude oil cloud point. This, however, is not the only factor that determines the efficiency of the additive as paraffin

    The number of people with disabilities in Brazil and worldwide has grown substantially in recent decades. Cross-cultural quality of life instruments can be helpful in the development of interventions designed to meet the needs of this population and contribute to rational allocation of resources. This study sought to provide evidence of validity and reliability the Brazilian Portuguese version of WHOQOL-Dis-D (a cross-cultural, multicentre instrument developed by the WHOQOL-Group for the assessment of quality of life in persons with physical disability - PD) and WHOQOL-Dis-ID (for persons with intellectual disability - ID). Classical psychometric methods were used to conduct independent analyses of the PD and ID samples. Criterion groups were established for analysis of construct validity. Concurrent validity was assessed in relation to SWLS and BDI-II scores; discriminant validity, in relation to WHODAS-II. Cronbach alpha was used to test the instrument scales and subscales for reliability. The ID subgroup was retested, and test-retest reliability assessed by means of intraclass correlation coefficients and paired Student's t-test. A total of 162 (98 females) people with PD and 156 (55 females) people with ID participated in the study. Cronbach alpha was satisfactory across practically all domains and factors in the PD subsample. In IDs, most factors or domains had coefficients higher than 0.70, but four subscales exhibited less satisfactory performance. Evidence of construct and concurrent validity and reliability were obtained. The analyses presented herein provide satisfactory evidence of the validity and reliability of the instrument and corroborated the factor structure revealed during cross-cultural research. Further studies with larger sample sizes are required to obtain additional evidence of validity and reliability.

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

    Full Text Available The present research seeks to understand to what extent companies in emerging countries, specifically, Brazilian, adopt dominant management practices, the so-called Euro-American practices, possess their one, or show a syncretism between the two. Methods: Mixed research. One phase was to collect data using a survey about cultural dimensions adopted from GLOBE (House 1998 management practices and also from Brazilian academy. Another was to collect data through interviews, which were analyzed in parallel. Results: Of the seven dominant cultural dimensions, indigenous practices influenced two. Another three were influenced by dominant management practices. Two of the local dimensions, even with internationalization, merged practices with Brazilian cultural traits. Even so, the practices derived from Jeitinho diminished relative to the international relations and experience of managers. Conclusions: The paper shows the existence of powerful Brazilian Indigenous Managerial Practices such as personalism and formalism. These practices have great influence on international business negotiations. On the other hand, it also shows that there are still dominant managerial practices specially in the case of more internationalized Brazilian managers

    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 Focus Group is a tool which generates, through interview sessions with a small number of participants, preliminary data to be used in subsequent quantitative stages. Many consumer studies use qualitative research with the aim of obtaining information and opinions on a specific product or situation. The objective of the present study was to obtain knowledge on the opinion, understanding and perception of the Brazilian consumer with respect to vegetables, focusing on organic products, using Focus Group Sessions. Four Focus Group Sessions were held with men and women in different environments, following a previously elaborated interview guide. In this study, it was observed that the consumers demonstrated being interested in having a healthy diet, based on fruit, vegetables and natural products. However, only a few declared consuming organic foods. Some participants did not know what the term organic meant, and most of them think that organic products are still very expensive, are not easily available in the supermarkets, do not have a good appearance, mainly in terms of size and packaging, and their certification is not always trustworthy. Almost all participants stated that they read package labels and among the items most observed were best-before date, nutritional information, production system and price. This study has identified important vegetable attributes perceived by the consumer, favouring the planning of a subsequent quantitative research. The results suggest that more information on the benefits of organic agriculture has to be passed on to consumers in order to contribute to a higher consumption of such products.Focus Group é uma ferramenta que permite obter, através de sessões de entrevistas com reduzido número de participantes, informação e opinião sobre algum produto ou serviço específico, as quais podem ser utilizadas em etapas quantitativas subseqüentes.

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

    Extremophiles are organisms adapted to grow at extreme ranges of environmental variables, such as high or low temperatures, acid or alkaline medium, high salt concentration, high pressures and so forth. Most extremophiles are micro-organisms that belong to the Archaea and Bacteria domains, and are widely spread across the world, which include the polar regions, volcanoes, deserts, deep oceanic sediments, hydrothermal vents, hypersaline lakes, acid and alkaline water bodies, and other extreme environments considered hostile to human life. Despite the tropical climate, Brazil has a wide range of ecosystems which include some permanent or seasonally extreme environments. For example, the Cerrado is a biome with very low soil pH with high Al+3 concentration, the mangroves in the Brazilian coast are anaerobic and saline, Pantanal has thousands of alkaline-saline lakes, the Caatinga arid and hot soils and the deep sea sediments in the Brazilian ocean shelf. These environments harbour extremophilic organisms that, coupled with the high natural biodiversity in Brazil, could be explored for different purposes. However, only a few projects in Brazil intended to study the extremophiles. In the frame of astrobiology, for example, these organisms could provide important models for defining the limits of life and hypothesize about life outside Earth. Brazilian microbiologists have, however, studied the extremophilic micro-organisms inhabiting non-Brazilian environments, such as the Antarctic continent. The experience and previous results obtained from the Brazilian Antarctic Program (PROANTAR) provide important results that are directly related to astrobiology. This article is a brief synopsis of the Brazilian experience in researching extremophiles, indicating the most important results related to astrobiology and some future perspectives in this area.

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

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

    Full Text Available A eletroquímica e a concentração de matéria orgânica nos horizontes superficiais de Latossolos correlacionam-se estreitamente. No presente trabalho, avaliaram-se as propriedades eletroquímicas do horizonte superficial de sete Latossolos brasileiros após a remoção das substâncias húmicas em meio alcalino. Os solos foram separados em dois grupos, segundo sua mineralogia, caulinítica e oxídica. O extrator NaOH 0,1 mol L-1 solubilizou substâncias húmicas correspondentes a menos de 3 % da MO total, indicando forte adsorção específica do material orgânico à fração mineral. A extração de ácidos húmicos e fúlvicos foi capaz de inverter o sinal de carga da superfície; no entanto, o efeito mais acentuado da retirada das substâncias húmicas solúveis foi a perda da capacidade-tampão das cargas do solo. A capacidade da dupla camada elétrica, uma medida indireta desse poder-tampão, aumentou de 3 a 15 vezes depois da extração das substâncias húmicas alcalino-solúveis. Solos com mineralogia predominantemente oxídica apresentaram maiores valores do ponto de efeito salino nulo, da capacidade da dupla camada elétrica, além da diminuição na capacidade de troca de cátions do que aqueles de natureza caulinítica.Electrochemistry and organic matter concentrations in the surface horizons of Oxisols are closely related. This study evaluated the electrochemical properties in the surface horizon of seven Brazilian Oxisols after the removal of humic substances by alkaline extraction. Based on their mineralogy the soils were grouped as kaolinitic or oxidic. Less than 3 % of the total organic matter were soluble humic substances extractable by NaOH 0.1 mol L-1, indicating their strong specific adsorption to the inorganic mineral sites. The removal of the humic and fulvic acids reversed the soil surface charge and also led to a marked loss in the buffering capacity of the soil charge. The electric double layer capacity, an indirect

    In Brazil there is intense research activity in nanotechnology, most of these developed in universities and research institutes. The Brazilian Nanotechnology Initiative (BNI) aims to integrate government actions to promote the competitiveness of the Brazilian industry. This initiative is founded on support for research and development in the laboratories of the National Laboratories for Nanotechnology (SisNANO), starting from an improvement in infrastructure and opening of laboratories for users of academia and business, promoting interaction and transfer knowledge between academia and business. Country currently has 26 thematic networks of nanotechnology, 16 -Virtual-National Institutes of Technology, seven National- Laboratories and 18 Associate Laboratories, which comprise the SisNANO. Seeking to expand and share governance with other government actors, the Interministries Committee for Nanotechnology was set up, composed of 10 ministries, and has the task of coordinating the entire program of the Federal Government Nanotechnology.Cooperation activities are an important part of BNI. Currently Brazil has cooperation programs with U.S., China, Canada and European Union among others. Recently, Brazil decided to join the European NanoReg program where 60 research groups are joining efforts to provide protocols and standards that can help regulatory agencies and governments.

    1995-11-01

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

    A space weather program is being initiated at the Brazilian National Institute for Space Research (INPE) to study events from their initiation on the sun to their impacts on the earth, including their effects on space-based and ground-based technological systems. The program is built on existing capabilities at INPE, which include scientists with a long tradition and excellence in the observation, analysis and modeling of solar and solar-terrestrial phenomena and an array of geophysical instruments that spans all over the Brazilian territory from the north to south of the magnetic dip equator. Available sensors include solar radio frequency receivers and telescopes, optical instruments and solar imagers, GNSS receivers, ionosondes, radars, allsky imagers, magnetometers and cosmic ray detectors. In the equatorial region, ionosphere and thermosphere constitute a coupled system with electrodynamical and plasma physical processes being responsible for a variety of peculiar phenomena. The most important of them are the equatorial electrojet current system and its instabilities, the equatorial ionization anomaly, and the plasma instabilities/irregularities of the night-time ionosphere (associated with the plasma bubble events). In addition, space weather events modify the equatorial ionosphere in a complex and up to now unpredictable manner. Consequently, a main focus of the program will be on monitoring the low, middle and upper atmosphere phenomena and developing a predictive model of the equatorial ionosphere through data assimilation, that could help to mitigate against the deleterious effects on radio communications and navigation systems. The technological, economic and social importance of such activities was recognized by the Brazilian government and a proposal for funding was approved for the period 2008-2011. New ground instruments will be installed during this period allowing us to extend our current capability to provide space weather observations, accurate

    Full Text Available Soil macrofauna is responsible for soil fertility through cycling of nutrients, tillage and fragmentation of organic matter, as well as through the association between groups of fauna with conserved and/or degraded pedoenvironments. Nevertheless, under the conditions of the Brazilian semi-arid region, there is little information about this resource. The objective of this study was to evaluate the epigeous macrofauna in successive cropping using previous green manure and subsequent planting of melon (Cucumis melo L. in Juazeiro county, Bahia, Brazil. Sampling dates were undertaken in November 2007 and February, April and July 2008, using traps containing 4 % formaldehyde for seven days in plots of 64 m2. Results obtained indicate that there is no difference among the treatments with mixed cover crops, and epigeous macrofauna is influenced by the time of collection. Diversity and uniformity are inversely correlated with total density of epigeous macrofauna. Diversification of plant species favors the increase of diversity and uniformity of epigeous macrofauna. Formicidae, followed by Isopoda, Coleoptera and Oligochaeta are the groups of fauna most numerous in the areas. A macrofauna do solo é responsável pela melhoria da fertilidade do solo através da ciclagem de nutrientes, revolvimento e fragmentação da matéria orgânica, como também, pela associação entre grupos de fauna com pedoambientes conservados e/ou degradados. No entanto, nas condições de semi-árido brasileiro pouca informação se tem a respeito deste recurso. Neste sentido, na região do sub-médio do Rio São Francisco, pólo de desenvolvimento da agricultura irrigada objetivou-se avaliar a macrofauna epígea em sucessão cultural utilizando prévia adubação verde e subseqüente plantio de melão (Cucumis melo L..

    Full Text Available The theme of corporate social responsibility (CSR has not been widely examined in the context of multinationals. This dearth is even greater with respect to subsidiaries, particularly the subject of reverse transfer of practices, that is, the transfer of practices developed in subsidiaries back to the parent company. Because of this theoretical gap, the present article investigates the factors involved on reverse transfer of CSR practices. The research hypotheses test the importance of developing nonlocation-bound capabilities, of integration between subsidiaries and parent and of institutional distance. The data were obtained by a survey of the main foreign subsidiaries in Brazil. All told, we analyzed 150 Brazilian subsidiaries of multinationals, by applying multiple linear regression. The results indicate that the reverse transfer of CSR depends on the development of nonlocation-bound capabilities of the subsidiaries and integration between the parent company and its foreign subsidiaries.

    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.

    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.

    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.

    To evaluate the quality of information about health and medication available on Brazilian websites. A descriptive study with a quantitative approach regarding Brazilian websites, conducted from January to March 2011. The search sites were located using two search phrases: "medication information" and "health information." The choice of variables was based on the Internet information quality criteria of the World Health Organization and the International Code of Ethics for health and services sites on the Internet. The dependent variable was whether the site had information about health or medication. The independent variables were access, appearance, organization, honesty, transparency, responsibility and origin. For statistical analysis, the χ² and Fisher exact tests were applied, with a significance level of 5%. Of the 37 Brazilian sites analyzed, 24 (64.9%) contained health information and 13 (35.1%) contained medication information. Regarding appearance, organization and access criteria, most sites related to health and medication were easily accessible, easy to understand, used objective language, were updated and organized logically and provided accurate and scientifically grounded information. The honesty criterion differed significantly between sites, and the quality of information presented on health and medication websites showed significant differences, suggesting the need for a more systematic organization of these topics on the Internet.

    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.

    2006-08-01

    Full Text Available Today, the quality of a scientific article depends on the periodical in which it is published and on the number of times the article is cited in the literature. In Brazil, the criteria for the evaluation of this scientific production are improving. However, there is still some resistance, with authors arguing that Brazilian publications must be preferentially addressed to the national readers and, therefore, they should ideally be written in Portuguese. In order to determine the kind of scientific journals cited in the reference lists of articles published in medical periodicals edited in Brazil, in the present study we determine the rate of Portuguese/English citations. Three issues of 43 periodicals (19 indexed in SciELO, 10 in PubMed, 10 in LILACS, and 4 in the ISI-Thompson base of different medical specialties were analyzed, and the number of both Portuguese and English citations in the reference list of each article was recorded. The results showed that in Brazilian-edited journals the mean number of citations/article was 20.9 ± 6.9 and the percentage of citations of international non-Brazilian periodicals was 86.0 ± 11.2%. Of the latter, 94.4 ± 7.0 are indexed by ISI-Thompson. Therefore, we conclude that Brazilian medical scientists cite the international non-Brazilian periodicals more than the national journals, and most of the cited papers are indexed by ISI-Thompson.

    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.

    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.

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

    To investigate frailty in Japanese, Brazilian Japanese descendants and Brazilian older women. The collected data included sociodemographic and health-related characteristics, and the frailty index Kihon Checklist. We analyzed the differences between the mean scores of Kihon Checklist domains (using ancova) and the percentage of frail women (using χ(2)-test). We carried out a binary logistic regression with Kihon Checklist domains. A total of 211 participants (Japanese n = 84, Brazilian Japanese descendants n = 55, Brazilian n = 72) participated in this research. The Brazilian participants had the highest total Kihon Checklist scores (more frail), whereas the Brazilian Japanese descendants had the lowest scores (P Brazilian group had more participants with oral dysfunction (P Brazilian women were likely to be more frail than the participants in other groups. More than the environment itself, the lifestyle and sociodemographic conditions could affect the frailty of older Brazilian women. © 2014 Japan Geriatrics Society.

    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.

    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.

    2015-03-01

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

    The article contextualizes the emergence of an international policy for the Brazilian Unified Health System as the common agenda of the Pan American Health Organization (PAHO) and the Brazilian Ministry of Health. For this purpose, two contextual axes were explored throughout the work. The first discusses the explicit relationship between the development-cooperation-health triad from an international perspective. The second examines the recent evolution of Brazilian foreign policy, particularly with respect to the role it is playing in South-South cooperation on health matters. The contextual framework that defines Brazilian international cooperation with PAHO is emphasized, above all with regard to the implementation of a specific cooperation agreement. The article concludes that this agreement, within the framework of South-South cooperation, is one of the principal institutional mechanisms established to bring about technical cooperation in health in the current setting.

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

    2017-07-01

    The article examines the conditions of production and recognition of scientific cinema in Brazil by comparing three distinct moments and contexts: the first moment takes place in the nineteenth century, and it is related to the contribution of a Brazilian astronomer otherwise little known to Brazilian film scholars, the second addresses Benedito Junqueira Duarte's voluminous mid-twentieth-century filmography, and the third moment documents recent scientific film experiences within ultra high resolution movies transmitted over photonic networks. Future trajectories for aesthetic concerns and practical issues such as the archiving of ultra high definition cinema are usefully informed by these histories of scientific cinema, even as a current generation of multidisciplinary teams including scientists, filmmakers, computer scientists, and network engineers reinvent, rediscover, and necessarily expand the scientific cinema toward concerns of real time collaboration and teaching.

    Full Text Available Within the setting of open market organizations, which in Brazil began to appear around the 1990s, efficiency has gained greater relevance. The objective of this paper is to study the efficiency of Brazilian airports through data envelopment analysis, using the Agência Nacional de Aviação Civil (ANAC and Empresa Brasileira de Infraestrutura Aeroportuária (INFRAERO databases from 2009, 2010, and 2011. The method was applied to study 16 Brazilian international airports with regards to financial variables. This approach showed that an airport’s size did not determine its efficiency. The use of resources to achieve production was the most relevant criterion for investigating the airport’s good performance and efficiency in the study presented herein.

    Full Text Available this research has identified Brazilian hosting networks through infrastructure services indicators that it was sold to tourists in organizations that form these networks. The theory consulted the discussion of structural techniques present in Social Network Analysis. The study has three stages: documental research, creation of Tourism database and interviews. The results identified three networks with the highest expression in Brazil formed by hotels, lodges, and resorts. Different char-acteristics of infrastructure and services were observed between hosting networks. Future studies suggest a comparative analysis of structural indicators present in other segments of tourism services, as well as the existing international influ-ence on the development of the Brazilian hosting networks.

  3. Brazilian Studies Then and Now

    Directory of Open Access Journals (Sweden)

    Anthony Pereira

    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.

  4. An overview of Brazilian mammalogy: trends, biases and future directions

    2009-03-01

    Full Text Available Mammals are among the most charismatic and well-studied organisms, and Brazil harbors the largest mammal diversity of the world. The Brazilian Society of Mammalogy was established in 1985, and since 2001 it organizes the Brazilian Congress of Mammalogy. We used the proceedings of all three editions of this congress together with papers indexed in Web of Science and Scielo to evaluate trends in Brazilian mammalogy. All contributions were categorized according to mammalian order, biome, topic of research and state of authors' affiliation. Our results show that mammalian orders with higher species richness receive more attention, but the ranking is different between abstracts and papers. Higher species richness did not translate into more attention for more speciose biomes, and again the ranking was different between papers and abstracts. There are research topics that receive much higher attention than others, and also other important ones, like Taxonomy, that have been neglected. States with greater human populations produce both more papers and abstracts. We conclude that the higher number of publication in the Atlantic Forest is caused by the concentration of mammalogists in the south and southeastern regions of the country. Contrary to what is normally believed, mammalian orders received attention according to their species richness, and not their charisma, probably because richer orders provide more study models. We suggest that additional funding mechanisms should be set in place in order to encourage more research on mammalian orders, topics, and states which have been neglected so far, in order to improve the knowledge on important Brazilian mammal biodiversity.

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

    Andrade, P P; Melo, M A; Kido, E A

    2014-12-01

    The Brazilian National Biosafety Committee approved in 2011 a new post release monitoring system for environmental releases of genetically modified organisms. It has a number of novel features in comparison with other established or proposed systems. The new system also allows the proponent to ask for monitoring exemption. General surveillance forms the basis of the monitoring system, similar to the European model, but differs markedly in the way it operates. While the European proposal is based on monitoring measurable variables extracted from environmental observations, from baselines previously established for multiple protection targets, the Brazilian system uses direct alerts of damage, without the aid of baseline values. The strength of the Brazilian form of monitoring is the possibility of generating an information network with the effective participation of many actors from the monitored area. A network constituted by highly qualified members, as proposed elsewhere, is too complex and unrealistic in Brazil and in many other countries. In conclusion, the Brazilian monitoring system is flexible and can be adjusted to the Brazilian reality over the next years, as a response to the ever growing experience in monitoring. It also meets the demands of the Brazilian society for transparency, rational use of resources, opportunity for national companies, and food and environmental biosafety.

    Full Text Available In Brazil the social management is configured in a complex process. This is due to its asymmetry with respect to economic policy, environmental policy and. Social management is a major challenge that involves the articulation of warranty rights, expanding the notion of social development, the role of the state and the search for a management paradigm that respects the new status given to the social area . The analysis focuses on the methods of social management in Brazil. Among the findings it is noted that the management models adopted in Brazil has proved insufficient. It is also noted that the ideas produced around a democratic-participative management creates tensions in the hegemony of the managerial organization in the country, so that tension may represent a potentiation between efficiency and democracy.

  15. 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.

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

    Approximately four million Africans were taken as slaves to Brazil, where they interbred extensively with Amerindians and Europeans. We have previously shown that while most White Brazilians carry Y chromosomes of European origin, they display high proportions of African and Amerindian mtDNA lineages, because of sex-biased genetic admixture. We studied the Y chromosome and mtDNA haplogroup structure of 120 Black males from Sao Paulo, Brazil. Only 48% of the Y chromosomes, but 85% of the mtDNA haplogroups were characteristic of sub-Saharan Africa, confirming our previous observation of sexually biased mating. We mined literature data for mtDNA and Y chromosome haplogroup frequencies for African native populations from regions involved in Atlantic Slave Trade. Principal Components Analysis and Bayesian analysis of population structure revealed no genetic differentiation of Y chromosome marker frequencies between the African regions. However, mtDNA examination unraveled considerable genetic structure, with three clusters at Central-West Africa, West Africa and Southeast Africa. A hypothesis is proposed to explain this structure. Using these mtDNA data we could obtain for the first time an estimate of the relative ancestral contribution of Central-West (0.445), West (0.431) and Southeast Africa (0.123) to African Brazilians from Sao Paulo. These estimates are consistent with historical information. Copyright 2008 S. Karger AG, Basel.

    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.

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

    One strategy to implement the rational use of medicines is the adoption of an 'essential medicines list'. The objective of this study was to analyze the list of medicines contained in the Brazilian National Relation of Essential Medicines (Rename, 2013) in terms of essentiality and rationality. Essentiality was determined by comparing this list to the 18th Essential Medicines List (EML) published by the World Health Organization (WHO). Drugs which were part of the Brazilian National Relation of Essential Medicines but not included in the EML were assessed using the classification described in La revue Prescrire to detect medications without added therapeutic value. It was discovered that the Brazilian National Relation of Essential Medicines contains 190 medications not included in the EML, of which 63 have no added therapeutic value. In addition, discrepancies were identified between the recommendations of the WHO and the drugs included in the Brazilian National Relation of Essential Medicines. It is concluded that drugs that are non-essential and provide no added therapeutic value should not be included in a list of essential medicines funded by the three Brazilian federal entities.

    2015-05-01

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

  8. 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.

    Feline immunodeficiency virus (FIV), like other retroviruses, displays large genomic divergence when different isolates are compared. In this study, 31 FIV positive samples of domestic cats from Porto Alegre, RS, Brazil were used aiming at a detailed genomic characterization and a better understanding of the molecular epidemiology of the virus in Brazil. The proviral env genes were partially amplified, sequenced and compared with another 237 sequences from different continents. We identified several Brazilian highly supported clades (A, B1, B2, C and D) that suggest independent events of introduction of FIV in Brazil. Forty six reference-sequences from the GenBank were used with our 31 sequences to infer the virus subtypes. Our sequences belong to the subtype B and three of them result from a recombination with the previously described subtype F. The other 28 Brazilian samples belonging to subtype B and another 46 Brazilian sequences from the GenBank were used to estimate the time to the most recent common ancestor of each Brazilian clade, using a Bayesian approach and a relaxed molecular clock model. The analyses of Brazilian sequences suggest several different entries of the virus in the Brazilian cat population between 1981 and 1991. Copyright © 2017 Elsevier B.V. All rights reserved.

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.

This alteration of land use may impart drastic changes in the soil attributes. In this context, this work aimed to evaluate the impact of Pinus taeda afforestation on soil chemical attributes and organic matter (SOM composition in Leptosols from Campos de Cima da Serra, RS. Soil samples under eight year old (Pi8 and 30 year old (Pi30 Pinus plantations and under native pasture (NP were studied. Contents of exchangeable cations and of micronutrients and soil pH were determined. The SOM composition was investigated by means of elemental analyses and FTIR spectroscopy. The soil under pasture had a higher content of nutrients and of SOM in comparison to Pinus soils, reflecting the higher input and decomposition rate of the below ground added residue in the grassland environment. The SOM in pasture soils showed a higher content of carbohydrate and of structures derived from microbial metabolism. Besides the depletion of nutrients and of SOM, Pinus afforestation affected the SOM quality: following afforestation, the proportion of chemically recalcitrant structures and of carboxylic groups increased, whereas N-containing groups decreased.Nas três últimas décadas, o cultivo de espécies exóticas vem sendo introduzido nas áreas de pastagem de solos de altitude localizados na região nordeste do Estado do rio Grande do Sul.

    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.

    The study's objectives were to evaluate a method for the determination of aflatoxins (AFs) in the Brazilian peanut confection "Paçoca" and to apply the method in investigating AF concentrations in Paçoca marketed in São Paulo State throughout 2013. Results of another survey conducted between 1994 and 2002 with another method were also reported. The current method consists of immunoaffinity column cleanup, LC with postcolumn derivatization for AF fluorescence enhancement, and fluorescence determination for the toxins. The mean recovery and mean RSD r values were 88.6 and 7.9%, respectively. The LODs for aflatoxin B 1 , aflatoxin B 2 , aflatoxin G 1 , and aflatoxin G 2 were 0.04, 0.01, 0.02, and 0.01 ng/g; and the LOQs were 0.15, 0.04, 0.07, and 0.04 ng/g, respectively. Results of the two survey studies indicate that the contamination of AFs in Paçoca remains a public health problem. In the 2013 survey, 71 of 100 samples (71%) had AFs contamination ranging from 0.3 to 41.8 ng/g, with 12 samples (12%) containing >20 ng/g of the toxins, whereas in the 1994-2002 survey, 73 of 150 samples (51%) had AFs contamination ranging from 9 to 1439 ng/g with 65 samples (45%) containing levels >20 ng/g.

The Virtual Herbarium provides an infrastructure that gathers digital records of plant specimens from primary source, mainly in Brazil, and makes them available through a central web portal. The source herbaria have complete control over what data is made through the portal and the data collected by BVH is made fully available. BVH in common with many data infrastructures, faces challenges in retaining funding. Most funding sources are project based and as has been noted elsewhere this creates problems for the sustaining of infrastructures. BVH therefore has an interest in demonstrating the use of the data resources it hosts. Through the OCSDNet project it has strengthened its capacity in this area to develop tools showing its wide usage. Overall the BVH hosts over eight million records (as of October 2017 and received 70 billion data requests in October 2017. Its users are mainly in Brazil but there is also substantial global usage. The primary uses are for research and education. There are a broad range of educational users, including universities but also schools. Through providing a central aggregation and access point BHV provides a data infrastructure that is greater – and more useful – than the sum of its parts.

  1. Educating Brazilian workers about AIDS.

    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.

    The aim was to analyse the implementation dynamics of the essential medicines list (EML). We used the government expenditures on medicines and Brazil as a case study. Drug purchases were considered as a proxy for utilization. The essential medicines (EMs) expenditures were followed over time by Brazilian National EMLs life-time and defined by broad therapeutic categories and by specific medicines. Brazil increased the number of the medicines during the last four editions of Brazilian National EMLs and the federal government expenditures on them. The EML implementation dynamics changed the distribution of expenditures on EMs. We identified a common set of 404 EMs present in all four editions of the Brazilian National EMLs. There was a proportional decrease in expenditures on anti-infectives for systemic use, blood and blood-forming organs and alimentary tract and metabolism, and increase in expenditures on antineoplastic and immunomodulating agents. The expenditures distribution per specific medicines revealed that a small set of EMs was responsible for 50% or more of expenditures considering Brazilian National EML life-time for all four periods. The increase in expenditures on EMs in Brazil was a consequence of the newer medicines incorporated over time in the Brazilian National EMLs. The use of the medicines expenditures as a source of data and the definition of an EML life-time permitted follow-up of the implementation dynamics of different versions of the Brazilian National EMLs. Our results have implications for policymakers and stakeholders to gain a better understanding of the role EMLs play in health system sustainability and in the provision of the most beneficial heath care. © 2017 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

    To evaluate whether there is any preference for citing journals from other countries to the detriment of Brazilian journals, in three Brazilian orthopedics journals. 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. 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. There is a need for Brazilian researchers to cite articles from Brazilian journals more often.

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

    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.

    This paper analyzes the profile of the Brazilian output in the field of multiple sclerosis from 1981 to 2004. The search was conducted through the MEDLINE and LILACS databases, selecting papers in which the term "multiple sclerosis" was defined as the main topic and "Brazil" or "Brasil" as others. The data were analyzed regarding the themes, the state in Brazil and institution where the papers were produced, the journals where the papers were published, journal's impact factor, and language. The search disclosed 141 documents (91 from MEDLINE and LILACS, and 50 from LILACS only) published in 44 different journals (23 of them MEDLINE-indexed). A total of 111 documents were produced by 17 public universities, 29 by 3 private medical schools and 1 by a non-governmental organization. There were 65 original contributions, 37 case reports, 20 reviews, 6 PhD dissertations, 5 guidelines, 2 validation studies, 2 clinical trials, 2 chapters in textbooks, 1 Master of Science thesis, and 1 patient education handout. The journal impact factor ranged from 0.0217 to 6.039 (median 3.03). Of 91 papers from MEDLINE, 65 were published by Arquivos de Neuro-Psiquiatria. More than 90% of the papers were written in Portuguese. São Paulo was the most productive state in the country, followed by Rio de Janeiro, Minas Gerais and Paraná. Eighty-two percent of the Brazilian output came from the Southeastern region.

    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.

    To characterize the participatory and democratic creation of the Brazilian guidelines for biorepositories and biobanks of human biological material with the purpose of research based on the ethical principles of human dignity, autonomy, beneficence, justice, and precaution. An interdisciplinary work group was constituted to prepare the document, considering the following criteria: experience in biobank operation, regional representation, type of stored biological material, and bioethics specialists. Members of the National Health Surveillance Agency (Agência Nacional de Vigilância Sanitária - ANVISA), also participated due to their regulatory competence. Members from the National Commission on Ethics in Research (Comissão Nacional de Ética em Pesquisa - Conep) participated as the social control organization. The document, based on ethical, legal, and technical guidelines, presents the concepts, activities, purposes, and differences between biorepositories and biobanks; forms of consent on the part of the subject; in addition to other aspects permeated by concerns regarding the appropriate use of information. The Brazilian guidelines for biorepository and biobank of human biological material with the purpose of research contains 39 articles, which are distributed in five chapters. The importance of legislation arises from the ethical concern, considering morals and taking into account the legal aspects, which translate into a document that does not end in itself. The dynamics of science always leads to changes in paradigms, which can go beyond the existing laws.

    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.

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

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

    Anthropometric data are essential for the design of military equipment including sizing of aircraft cockpits and personal gear. Currently, there are no anthropometric databases specific to Brazilian military personnel. The aim of this study was to create a Brazilian anthropometric database of Air Force pilots. The methods, protocols, descriptions, definitions, landmarks, tools and measurements procedures followed the instructions outlined in Measurer's Handbook: US Army and Marine Corps Anthropometric Surveys, 2010-2011 - NATICK/TR-11/017. The participants were measured countrywide, in all five Brazilian Geographical Regions. Thirty-nine anthropometric measurements related to cockpit design were selected. The results of 2133 males and 206 females aged 16-52 years constitute a set of basic data for cockpit design, space arrangement issues and adjustments, protective gear and equipment design, as well as for digital human modelling. Another important implication is that this study can be considered a starting point for reducing gender bias in women's career as pilots. Practitioner Summary: This paper describes the first large-scale anthropometric survey of the Brazilian Air Force pilots and the development of the related database. This study provides critical data for improving aircraft cockpit design for ergonomics and comprehensive pilot accommodation, protective gear and uniform design, as well as digital human modelling.

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

    2015-09-01

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

    Brazilian Quilombolas are communities composed of African-derived populations that have their territories guaranteed by the Brazilian Constitution. The present study investigated the hemoglobin (Hb) variants among these population groups. This study was conducted in a total of 2843 individuals of Brazilian Quilombola communities of the Bahia, Pará, and Piauí states. All the participants had their Hb profiles evaluated. The Hb S (HBB: c.20A>T) variant was described in all the studied localities. However, the individuals in Bahia State had the highest frequency of the Hb C (HBB: c.19G>A) variant; individuals from Piauí State had a higher frequency of the Hb D-Punjab (HBB: c.364G>C) variant compared to the other states, and individuals from Pará State only carried the Hb S variant. The present study revealed a specific distribution of Hb variants that could represent different waves of African influence in these Brazilian populations.

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

    Full Text Available 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.

    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

    The growth of youth with Down syndrome (DS) differs from that of youth without DS, and growth charts specific to DS have been developed. However, little is known about the growth of Brazilian youth with DS. The objective of this study was to construct growth charts for Brazilian youth with DS and compare the growth data with the Child Growth Standards of the World Health Organization (WHO) and charts for children with DS from other studies. Mixed longitudinal and cross-sectional data were collected at University of Campinas, 48 specialized centers for people with intellectual disabilities, and two foundations for people with DS between 2012 and 2015. A total of 10,516 growth measurements from birth to 20 years of age were available from 938 youth with DS (53.7% boys) born between 1980 and 2013. The Lambda Mu Sigma method was applied to construct the curves using generalized additive models for location, scale, and shape. Length/height-for-age, weight-for-age, and head circumference-for-age percentile curves were generated for Brazilian boys and girls from birth to 20 years of age. Differences in growth of Brazilian youth ranged from -0.8 to -3.2 z-scores compared to WHO standards, and -1.9 to +1.3 compared to children with DS in other studies. These specific growth charts may guide clinicians and families in monitoring the growth of Brazilian children and adolescents with DS. Copyright © 2017 The Authors.

    Full Text Available Objective: this work deals with the development of the Brazilian experimental physiology in late nineteenth-century. Content: it analyzes some experiments on toxic plants, the nutritional effects of coffee, herb mate, dried meat and the food consumption in hot and cold environments, held at the Laboratory of Experimental Physiology in the National Museum of Rio de Janeiro, created in 1880. This laboratory was financed by the Imperial Government, Ministry of Agriculture, and personally supported by the emperor Pedro II. It was created and headed by the Brazilian Physician João Baptista Lacerda and the French physiologist Louis Couty. Conclusions: While its organization was based on the European physiology, its researches privileged national themes. The physiologists were interested not only on the classical issues of physiology, but on the plants and natural products that played a role on the Brazilian economy. They even created their own experimental apparatuses, such as a cold chamber for climatic studies. In order to legitimate the Brazilian physiology, in Brazil and abroad, the researchers associated scientific and practical in­terests in their studies. The chance of social-economical use of their studies could explain the interests of the Brazilian elite and the support of the Ministry of Agriculture.

  7. Representatividade e inovação na governança dos processos participativos: o caso das organizações Brasileiras de agricultores familiares Representativeness and innovation in the management of the participatory processes: the case of the Brazilian organizations of family farmers

    regarding the use of the public - and, largely, private - resources of a region. Despite the obvious democratic virtues of the participatory processes, there has been a recent increase in the critical literature, questioning their results. This paper intends to reveal the tension experienced by the contemporary social movements: the conflict between representativeness and innovation. Representative movements tend to consolidate and strengthen interests, and their institutionalization pushes them towards routine attitudes that often block their innovative potential. One way out of the impasses of the social movements is in the terms of management of the social participation focused explicitly on learning and innovation. Organizations coming from social movements are an essential part of the participatory processes. This article, based on the example of the Brazilian policy of strengthening family agriculture, examines two of those organizations whose origin is in the social movements: the Federação dos Trabalhadores na Agricultura Familiar - FETRAF (Federation of Workers in Family Farming, which is a trade union; and the CRESOL System of cooperatives for credit outreach. Both organizations stimulate participatory processes and are associated with government policies. In the case of the trade union, however, social participation does not result in innovation, and the ties with the government tend to restrict the movement to relations already known. As regards the credit cooperative, social participation and ties with the government are the result of incentives that encourage the strengthening of what the new economic sociology calls weak ties, and thus open the way to expand the very foundations of the processes of local development.

  8. [Brazilian colonization in the Paraguayan agricultural frontier].

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

    Full Text Available This article presents results of two researches on urban policies in different Brazilian metropolises using network analysis. Policy network studies have explored the consequences of networks over policies, but have underestimated the consequences of the structure of the network itself. The institutional and personal networks that structure state organizations internally and insert them in broader political scenarios organize a mid-level structure I call State fabric. This introduces more stability and predictability than usually considered and gives access to a specific power resource, which I call positional power, associated with the positions political actors occupy in the State fabric, influencing politics inside and around the State.

    Full Text Available This paper is about the semantics and the syntax of aspectual verbs in European and Brazilian Portuguese. Some of these verbs select a+Infinitive in the European variety whereas the same verbs select that structure and Gerund in the Brazilian variety. We show that this discrepancy can be explained in semantic and syntactic grounds due to the different nature of the semantic ‘input’ (stative or eventive, the availability of tense constructions and the functional structure of the embedded domain. Another group of aspectual verbs do not differ in their syntactic structure in the two varieties as their structure (de+Infinitive is the same, although syntactically different from a+ Infinitive, but they do differ in their semantics and also in the selection of different verbs.

    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 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 tested. Although erythromycin (MIC90 0.75 microg/ml) and azithromycin (MIC90 0.064 microg/ml) were active against C. diphtheriae in this study, 4.2% of the strains showed decreased susceptibility (MIC 1.0 microg/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 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.

This is due to initiatives among various stakeholders, including national and state government and agents, farmers, consumers, funding agencies and non-governmental organizations. Change has come both from bottom-up and top-down actions of these stakeholders, providing leadership, financing and monitoring to foster environmental sustainability and agricultural growth. Goals to reduce greenhouse gas emissions from land-cover and land-use change in Brazil are being achieved through a multi-tiered approach that includes policies to reduce deforestation and initiatives for forest restoration, as well as increased and diversified agricultural production, intensified ranching and innovations in agricultural management. Here, we address opportunities for the Brazilian Amazon in working towards low-carbon rural development and environmentally sustainable landscapes.

    Full Text Available The aim of this study is to explore and validate the dimensions of IT Portfolio Management (ITPM in Brazilian companies, based on three different models. Five case studies were carried out in Brazilian companies that invest more than nine million reals per year in IT. Eight top IT executives from those organizations who had knowledge of the dimensions of ITPM were interviewed. Items were modified and new items included within the dimensions, while examples of equipment or systems applicable to each of the four dimensions were also identified. Research that helps managers to better understand and structure their IT investments by using the dimensions of ITPM is important to assist in the management of such resources. ACKNOWLEDGEMENTS. The authors wish to thank CNPq and CAPES for their financial support during the development of this research.

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

    This paper measures the degree of segmentation in the brazilian labor market. Controlling for observable and unobservable characteristics, workers earn more in the formal sector, which supports the segmentation hypothesis. We break down the degree of segmentation by socio-economic attributes to identify the groups where this phenomenon is more prevalent. We investigate the robustness of our findings to the inclusion of self-employed individuals, and apply a two-stage panel probit model using ...

    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.

    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.

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

    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)

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

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

    This study aimed to characterize the clinical trials with medicines enrolling Brazilian children and adolescents, registered in the databases of Clinical Trials and the Brazilian Clinical Trials Network (ReBEC) from 1994 to 2014. Only 462 clinical trials enrolled Brazilian children and adolescents. There was an increase in registrations beginning in 2003, with an important drop in 2011. Among these trials, 35.5% were hosted in Brazil. The international clinical trials were mostly conducted by North American companies. In both cases, multinational industry was the principal source of funding. The clinical trials were predominantly phase III with injectable and solid oral pharmaceutical forms of antiviral drugs. Domestic clinical trials showed wider variation in the pharmaceutical forms and higher percentage of liquid formulations, when compared to the international trials. In addition to heavy external dependence for conducting clinical trials, the study emphasized the challenge for pediatric care in Brazil, which presents epidemiological peculiarities in an environment prone to the use of unlicensed medicines for children.

    Quality indicators for the Brazilian cervical cancer screening programme can provide a perspective on its effectiveness in Brazilian macro-regions and states. The aim of this study was to perform a trend analysis of the cervical cancer screening program's quality indicators, according to Brazilian regions and states, from 2006 to 2013. Using information from approximately 62,000,000 exams obtained from the Information System of Cervical Cancer Screening (SISCOLO), joinpoint analysis was used to calculate the Annual Percentage Change (APC). The estimated number of women in the target age group (25-64 years) who underwent Pap testing over a three-year interval was lower than that recommended by international guidelines in the North, Northeast and Midwest regions, and the trends for this indicator remained stationary over the years in all regions of Brazil. Overall, the index of positivity in Brazilian regions and states is below that preconized by the Brazilian National Cancer Institute (INCA). Additionally, the frequencies of unsatisfactory cases are in line with international guidelines but above those preconized by INCA guidelines. All positive cytological diagnoses were lower than those preconized by INCA. The results show that the cervical cancer screening programme is still far from efficient because most of the quality indicators in Brazilian regions and states are outside of the parameters preconized by national and international organizations.

    Ygor Jacques Agra Bezerra da Silva

    Full Text Available ABSTRACT: Studies regarding background concentrations of rare earth elements (REEs are scarce and have mainly focused on a limited number of soil types from the northern hemisphere. The aim of this study was to determine REE concentrations in thirty-five benchmark soils of Brazil. Composite soil samples were taken from areas under native vegetation or with minimal anthropogenic influence. Concentrations of La, Ce, Pr, Nd, Sm, Eu, Gd, Yb, Lu, Dy, Er, Ho, Tb, Tm, Y, Sc, and Fe were determined by ICP-OES using a cyclonic spray chamber/nebulizer system after microwave acid digestion. Results were assessed by descriptive statistics, Pearson correlation, and principal component analysis (PCA. Regression analyses among Fe, organic carbon, and REEs were performed to provide a tool for estimating REE concentrations in soils. The REE concentrations in the Brazilian benchmark soils were in the following order: Ce > La > Nd > Pr > Y > Sm > Gd > Sc > Dy > Yb > Eu > Er > Tb > Ho > Lu > Tm. The clear decoupling between light and heavy rare earth elements in soils, indicated by multivariate analysis, is mainly related to differences in parent material. The lowest REE concentrations were found in sandy sediments, whereas the highest REE concentrations were observed in basalt, biotite gneiss, and clayey sediments. The organic carbon and Fe concentrations can properly predict REE concentrations in soils; such a finding can assist in estimating REE concentrations in soils not only in Brazil but also in similar soils developed under tropical conditions.

    Structurally colored nano-architectures found in living organisms are complex optical materials, giving rise to multiscale visual effects. In arthropods, these structures often consist of porous biopolymers and form natural photonic crystals. A signature of the structural origin of coloration in insects is iridescence, i.e., color changes with the viewing angle. In the scales located on the elytra of the Brazilian weevil Entimus imperialis (Curculionidae), three-dimensional photonic crystals are observed. On one hand, each of them interacts independently with light, producing a single color which is observed by optical microscopy and ranges from blue to orange. On the other hand, the color perceived by the naked eye is due to multi-length-scale light effects involving different orientations of a single photonic crystal. This disorder in crystal orientations alters the light propagation in such a way that the crystal iridescence is removed. Entimus imperialis is therefore a remarkable example of additive photonic colors produced by a complex multi-scale organic architecture. In order to study this specific natural photonic structure, electron microscopy is used. The structure turns out to be formed of a single type of photonic crystal with different orientations within each scale on the elytra. Our modeling approach takes into account the disorder in the photonic crystals and explains why the structure displays bright colors at the level of individual scales and a non-iridescent green color in the far-field.

    This study aims to present the percentages of the Brazilian population holding health insurance plans, itemized by social-demographic characteristics, based on the data of the National Health Survey carried out in 2013, and to compare this information with the administrative data of the National Supplementary Health Agency for the same year. Data from the National Health Survey, and from the Beneficiaries Information System of the National Health Agency for the year 2013, were used. The percentage of people having a health plan was described according to stratification for: all of Brazil, urban/rural, Brazilian official Regions, Brazilian States and state capitals, gender, age group, level of schooling, position in the workforce, ethnic classification, and self-assessed state of health. Results include the following: The percentage of people saying they had some health plan in Brazil was 27.9% (CI 95%: 27.1-28.8). A significant difference was found relating to level of schooling - the percentage being highest for those who stated they had complete secondary education (68.8% CI 95%: 67.2-70.4) and for those who said they were currently in work (32.5% CI 95%: 31.5-33.5). The increase in health plan coverage in the Brazilian population reflects the improvement of the suply of employment and the growth in the country's economy.

    This study examined the muscle power of Brazilian circumpubertal girls and extended the analysis to a cross-cultural dimension. A total of 462 children, 123 Brazilian girls and 339 French girls, 9-18 years, participated in this investigation. Anthropometric data included body mass (BM), height, skinfold thicknesses, and estimated lean leg volume (LLV). All subjects completed a physical activity questionnaire. Cycling peak power was measured including the flywheel inertia of the device (CPPi). Brazilian girls self-assessed their maturation using pubic hair development. CPPi and optimal velocity (v(opt) = velocity at CPPi) increased with stages of puberty. A multiple stepwise regression with anthropometric variables as explanatory factors showed only LLV and age explaining the variance of CPPi (R2 = 0.40, P CPPi in Brazilian girls was related to undetermined qualitative individual factors, which may be related to cycling skill. Even when normalized for anthropometric variables, the anaerobic performance (CPPi and v(opt)) of Brazilian girls was significantly lower than a cohort of French girls. The latter demonstrated a high participation in sport and training activities, while 50% of the Brazilian girls had only physical education classes in the form of regular physical activity. Moreover, most of the Brazilian girls demonstrated an ineffective sprint cycling skill. The data suggest that motor learning is an important issue in muscle power assessment and might, therefore, partially explain peak power differences in Brazilian compared with French girls.

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

    2015-01-01

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

    Cystathionine beta-synthase (CBS) deficiency is the most common cause of homocystinuria. However, no data are available concerning the molecular basis of this disease in Brazilian populations. We studied 14 Brazilian patients from 11 unrelated families using a combined screening approach, involving restriction analysis, single-strand conformational polymorphism (SSCP) scanning, and sequencing. All patients presented homocysteine levels higher than 200 mumol/l before the beginning of treatment. The most common CBS gene mutations, p.G307S (c.919G > A) and p.I278T (c.833T > C), were evaluated and the allele c.919A was not found. One allele with the c.844 ins68 (4.5%) in the CBS gene was found. Three families (6 patients) presented the allele c.833 C (13.6%), without the insertion in the heterozygous state. SSCP scanning and sequencing showed 3 alleles p.T191M (13.64%) in 2 families. One allele with a novel mutation was found in exon 4 (c.168T > A) of the CBS gene (4.5%). We also analyzed c.677C > T and c.1298A > C polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene and the 2756A > G polymorphism in the methionine synthase (MTR) gene. The frequencies of mutated alleles were: 50% c.677T and 18.2% c.1298C for MTHFR, and 27.3% c.2756G for MTR. In spite of the high level of racial mixing in the country, Brazilian homocystinuric patients did not present a high prevalence of the most common mutations described in the literature.

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

    Full Text Available 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%. In total, 58 patients with cirrhosis had their diagnosis by ultrasound confirmed by computed tomography or magnetic resonance imaging. Of these, 55% had 1 nodule; 17%, 2 nodules; and 28%, ≥3 nodules. CONCLUSIONS: Nonalcoholic steatohepatitis is a relevant risk factor associated with hepatocellular carcinoma in

    With the financial market globalization, foreign investments became vital for the economies, mainly in emerging countries. In the last decades, Brazilian exchange rates appeared as a good indicator to measure either investors' confidence or risk aversion. Here, some events of global or national financial crisis are analyzed, trying to understand how they influenced the "dollar-real" rate evolution. The theoretical tool to be used is the López-Mancini-Calbet (LMC) complexity measure that, applied to real exchange rate data, has shown good fitness between critical events and measured patterns.

    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.

    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.

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

    To estimate the prevalence of root caries in Brazilian adults and elderly. We assessed data from the Brazilian Oral Health Survey (SBBrasil 2010). Dental examinations were performed on 9,564 adults and 7,509 elderly individuals in households in the 26 state capitals, the Federal District and 150 provincial towns. Diagnostic criteria and data assessment tools were those standardized by the World Health Organization. The outcome was measured by using root caries index and the index of decayed and filled dental roots. The prevalence of root caries was 16.7% in adults and 13.6% in the elderly. The index of decayed and filled dental roots was 0.42 and 0.32 for adults and the elderly respectively, with most of the index represented by untreated caries. The prevalence of root caries differed significantly among states capitals and provincial towns, with higher values being reported in the state capitals in the North and Northeastern Brazilian regions. In adults, the root caries index ranged from 1.4% in Aracaju to 15.1% in Salvador (both in the Northeast). Among the elderly, this index ranged from 3.5% in Porto Velho to 29.9% in Palmas (both North). Root caries was more prevalent in men than in women in both age groups. There is a wide variation in root caries indices in adults and in the elderly, and between and within Brazilian regions. Most root caries is untreated. We recommend the incorporation of this disease into the oral health surveillance system.

    Full Text Available OBJECTIVE: To describe the distribution of edentulism and estimate the prevalence of functional dentition and shortened dental arch among elderly population. METHODS: A population-based epidemiological study was carried out with a sample of 5,349 respondents aged 65 to 74 years obtained from the 2002 and 2003 Brazilian Ministry of Health/Division of Oral Health survey database. The following variables were studied: gender; macroregion of residence; missing teeth; percentage that met the World Health Organization goal for oral health in the age group 65 to 74 years (50% having at least 20 natural teeth; presence of shortened dental arch; number of posterior occluding pairs of teeth. The Chi-square test assessed the association between categorical variables. The Kruskal-Wallis and Mann-Whitney tests were used to assess differences of mean between number of posterior occluding pairs teeth, macro-region and gender. RESULTS: The elderly population had an average of 5.49 teeth (SD: 7.93 with a median of 0. The proportion of completely edentulous respondents was 54.7%. Complete edentulism was 18.2% in the upper arch and 1.9% in the lower arch. The World Health Organization goal was achieved in 10% of all respondents studied. However, only 2.7% had acceptable masticatory function and aesthetics (having at least shortened dental arch and a mean number of posterior occluding pairs of 6.94 (SD=2.97. There were significant differences of the percentage of respondents that met the World Health Organization goal and presence of shortened dental arch between men and women. There were differences in shortened dental arch between macroregions. CONCLUSIONS: The Brazilian epidemiological oral health survey showed high rate of edentulism and low rate of shortened dental arch in the elderly population studied, thus suggesting significant functional and aesthetic impairment in all Brazilian macroregions especially among women.

    Brazil is one of the world's leading producers and exporters of agricultural goods. Despite undergoing significant increases in its cropland area in the last decades, it remains one of the countries with the most potential for further agricultural expansion. Most notably, the expansion in production areas of commodity crops such as soybean, corn, and sugarcane has become the leading cause of land cover conversion in Brazil. Natural land covers, such as the Amazon and Cerrado forests, have been negatively affected by this agricultural expansion, causing carbon emissions, biodiversity loss, altered water cycles, and many other disturbances to ecosystem services. Monitoring of change in cropland area extent can provide relevant information to decision makers seeking to understand and manage land cover change drivers and their impacts. In this study, the freely-available Landsat archive was leveraged to produce a large-scale, methodologically consistent map of cropland cover at 30 m. resolution for the entire Brazilian territory in the year 2000. Additionally, we mapped cropland expansion from 2000 to 2013, and used statistical sampling techniques to accurately estimate cropland area per Brazilian state. Using the Global Forest Change product produced by Hansen et al. (2013), we can disaggregate forest cover loss due to cropland expansion by year, revealing spatiotemporal trends that could advance our understanding of the drivers of forest loss.

    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 Abstract For the efficiency of sales and marketing management of athletic clubs, it is crucial to find a way to appropriately estimate the level of demand for sporting events. More precise estimates allow for an appropriate financial and operational plan and a higher quality of service delivered to the fans. The focus of this study is to analyze and forecast the ticket consumption for soccer games in Brazilian stadiums. We compare the results of the regression model with normally distributed errors (benchmark, the TOBIT model and the Gamma generalized linear model. The models include explanatory variables related to the economic environment, product quality, as well as monetary and non-monetary incentives that people are given to attend sporting events at stadiums. We show that most of these variables are statistically significant to explain the amount of fans that go to stadiums. We used different measures of accuracy to evaluate the performance of demand forecasts and concluded that Gamma generalized linear model presented better results to forecast the ticket consumption for Brazilian championship games, when compared to a benchmark.

    Different types of mutations in the DMD gene underlie Duchenne muscular dystrophies (DMD) and Becker muscular dystrophies (BMD). Large deletions and duplications are the most frequent causative genetic alterations worldwide, but little is known about DMD/BMD genetic profile in Brazil. Hence, we recruited patients with DMD and BMD from 8 neuromuscular reference centers along the country, and performed a comprehensive molecular investigation that included Multiplex Ligation-dependent Probe Amplification and Next generation sequencing (NGS) analyses. We evaluated 199 patients from 177 unrelated families: 166 with DMD, 32 with BMD and 1 1.5 years old asymptomatic patient with persistent hiperCKemia. Overall, large deletions (58.2%) followed by nonsense mutations (12.4%) and large duplications (11.3%) were the most frequent variants in Brazilian families. Large deletions were less frequent in BMD than in DMD (44.8% vs 60.8%). We identified 19 new DMD variants. Nonsense mutations were significantly more frequent in patients from northeastern region than from southern/southeastern regions of Brazil (27.7% vs 8.5%, P profile of Brazilian patients with DMD/BMD is similar to previously reported cohorts, but it is not uniform across the country. This information is important to plan rational clinical care for patients in face of the new coming mutation-specific therapies. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    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 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.

    The opossum has been suggested as an animal model for biomedical studies due to its adaptability to captivity and number of births per year. Despite many studies on morphology and experimental neurology using this opossum model, the literature does not offer details of the nerves of the lumbosacral plexus in this species. Ten lumbosacral plexus were dissected to describe the peripheral innervations of the Brazilian Common Opossum (Didelphis aurita) and compare the results with Eutheria clade species. The tensor fasciae latae muscle was absent and there was only one sartorius muscle for each limb. The distribution of the nerves were similar to other mammals, except for the caudal gluteal nerve, sartorius muscle innervations and the position of the pudendal nerve which arose from the major ischiatic foramen together with the ischiatic nerve, the cranial gluteal nerve and the caudal gluteal nerve. No anatomical variation was found. The special position of the pudendal nerve suggested that the Brazilian Common Opossum is a better model than rats or rabbits in surgical procedures with that specific nerve. In addition, the study revealed that the pelvic limb nerves are not an invariable structure of reference for muscle homology and homonym as reported previously. New investigation using other species of opossums are necessary to best comprehend the lumbosacral plexus distribution in the Methatheria clade and to confirm that other opossum species is eligible as a good model for pudendal nerve studies.

    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.

    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. macaçar. 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 (˜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 disinfection process, without impairing the biological quality of the valuable bean protein.

    To divulge information on the chemical composition and physical-chemical features of some mineral waters from Brazilian natural sources that will be of useful protocol investigation and patient advice. The survey was based on bottle labels of non-gaseous mineral waters commercially available in the city of Rio de Janeiro. The íon concentration of each mineral was calculated from the salt content. 36 springs were enralled from different states of the country. The pH (25 degrees C), 4.1 to 9.3, varied on dependence of the source and it was linearey correlated with the cations calcium, magnesium and sodium and the anion bicarbonate. It was atributed to high alkalinity (about 70% of bicarbonate in the molecula-gram) of these salts. The calcium (0.3 to 42 mg/l), magnesium (0.0 to 18 mg/l) and bicarbonate (4 to 228 mg/l) contents are relatively low. The mineral content of the Brazilian springs enrolled in this survey is low; about 70% of the sources having calcium and magnesium less than 10 mg/l and 1.0 mg/l, respectively, similar to local tap water.

    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 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.

    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.

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

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

    The hydrological periods drive the structure and organization of aquatic communities in semiarid regions. We hypothesize that a decrease of the precipitation during the dry period will favor the development of the periphytic algal community, leading to higher richness and density in this period. To test this hypothesis, we investigated the changes in the periphytic algal community structure in three shallow and eutrophic ecosystems of the Brazilian semiarid. The sampling was performed between 2007 and 2010 at two-mensal intervals. The sampling of periphytic algal was performed in aquatic macrophytes and rocks. The abiotic variables were analyzed simultaneously. Dominance in diatoms, cyanobacteria and chlorophytes, respectively, was observed in two periods. In the dry period, waters were alkaline and had high concentrations of nitrate and total phosphorus associated with the highest densities of Bacillariophyceae. In the rainy period the water was warmer, oxygenated and high concentrations of ammonia and soluble reactive phosphorus with diatoms remained dominant but with reduced density, while cyanobacteria and chlorophytes increased. Overall, periphytic algal community composition no responded to changes in the hydrological periods. However, the hydrological periods altered the dynamics of periphytic algal community, supported by the alternation of the most representative classes (diatoms and cyanobacteria) between the hydrologic periods. Our data suggest that the morphometric and chemical and physical characteristics of lentic aquatic ecosystems studied were more important in the dynamics of periphytic algal community than the hydrological periods and types of substrates.

    The aim of this study was to describe the prevalence of biochemical markers and associate with obesity in Brazilian adolescents enrolled in public schools in a rural area. The sample consisted of 199 adolescents between 10 to 14 years old from Piracicaba, Brazil. The obesity was measured by body mass index (BMI and according to the World Health Organization curves. We collected blood for biochemical markers analysis (total cholesterol, high density lipoprotein, low density lipoprotein, triacylglycerol, insulin and glycemia. Mann Whitney test was used to compare continuous variables between sexes. Chi-square test was used to compare proportions. To investigate the association between the independent variables and biochemical markers a multiple logistic regression model was performed. Among 199 adolescents, 23.1% was obese and 65.8% were insufficiently active. A high prevalence of dyslipidemia (71.4% was observed, whereas the low levels of high density lipoprotein (40.7% were the most prevalent. An association between obesity and undesirable values for high density lipoprotein, triacylglycerol and insulin resistance was found. Obese adolescents were less likely to present a desirable value for high density lipoprotein. It is understood that obesity is detrimental to metabolic profile and should be prevented and treated even in adolescence.

    Contamination of bee products may occur during packing or even during the process of collection. Gamma irradiation was found to decrease the number of bacteria and fungi. However, little information is available on the effects of gamma irradiation on viscosity which is an important property of honey. In this work the viscosity of two varieties of Brazilian honey was measured when they were irradiated at 5 and 10 kGy. The viscosity was measured at four temperatures (25°C, 30°C, 35°C and 40°C) for both samples and compared with control and within the doses. The sensory evaluation was carried on for the parameters color, odor, taste and consistency, using a 9-point hedonic scale. All the data were treated with a statistical tool (Statistica 5.1, StatSoft, 1998). The viscosity was not impaired significantly by gamma irradiation in doses 5 and 10 kGy ( psensorial characteristics (odor, color, taste and consistency) is presented. The taste for Parana type indicated a significant difference among irradiation doses ( p<0.05) but the higher value was for 5 kGy dose, demonstrating the acceptability for this case. The Organic honey presented the taste parameter for 10 kGy, significantly lower than the control mean but it did not differ significantly from the 5 kGy value.

    Full Text Available This paper presents the results of a research that aimed at developing a financial analysis of a sample of Brazilian hospitals between 2006 and 2011. The data were collected from financial statements of 23 hospitals and from the Database of United Health System. These secondary data were analyzed through the following techniques: descriptive statistics, Spearman’s correlation, Kolmogorov-Smirnov’s test, Kruskal-Wallis’ test and Chi-square’s test. It was verified that the sample presents unsatisfactory general results about financial performance, especially when related to financial ratios of profitability and return. However, the analysis of different categories of hospitals displays relevant and significant divergences, especially about the type of hospitals: publics and voluntaries ones. The voluntary hospitals present higher liquidity ratios and the best profitability and their capital structure usually focus on long term financing obtained from external agents. These evidences suggest that those organizations focus on financial leverage to achieve better results without deteriorate their liquidity. On the other hand, the public hospitals present lower liquidity as well as worse profitability and return ratios. It was verified that the large-sized hospitals usually present lower financial ratios (liquidity, profitability and return than the medium-sized hospitals.

    A focused and commented review on the impact of dermatologic diseases and interventions in the solidary act of donating blood is presented to dermatologists to better advise their patients. This is a review of current Brazilian technical regulations on hemotherapeutic procedures as determined by Ministerial Directive #1353/2011 by the Ministry of Health and current internal regulations of the Hemotherapy Center of Ribeirão Preto, a regional reference center in hemotherapeutic procedures. Criteria for permanent inaptitude: autoimmune diseases (>1 organ involved), personal history of cancer other than basal cell carcinoma, severe atopic dermatitis or psoriasis, pemphigus foliaceus, porphyrias, filariasis, leprosy, extra pulmonary tuberculosis or paracoccidioidomycosis, and previous use of etretinate. Drugs that impose temporary ineligibility: other systemic retinoids, systemic corticosteroids, 5-alpha-reductase inhibitors, vaccines, methotrexate, beta-blockers, minoxidil, anti-epileptic, and anti-psychotic drugs. Other conditions that impose temporary ineligibility: occupational accident with biologic material, piercing, tattoo, sexually transmitted diseases, herpes, and bacterial infections, among others. Thalidomide is currently missing in the teratogenic drugs list. Although finasteride was previously considered a drug that imposed permanent inaptitude, according to its short halflife current restriction of 1 month is still too long. Dermatologists should be able to advise their patients about proper timing to donate blood, and discuss the impact of drug withdrawal on treatment outcomes and to respect the designated washout periods.

    The occurrence of occupational accidents is common among students and dentists. The present study is aimed to evaluate the prevalence and characteristics of needlestick and sharp instrument injuries among dentistry students. A documentary research was carried out with data being obtained from the analysis of 137 medical records of injuries caused by needlestick and sharp instruments occurring in the period from 2012 to 2016 and were analyzed regarding the characteristics of the victim (gender and age) and the accident (year, time, environment, and time interval between exposure and search for care). Data were organized in the Statistical Package for Social Sciences software version 18 and were presented through descriptive statistics. The occurrence of accidents was high (43.1%), with the predominance of female victims (66.1%) and aged up to 23 years (55.9%). The majority of events occurred in the afternoon (54.4%), in the clinical setting (70.7%), and in 75% of the cases, the search for care occurred within 2 h after exposure. Accidents with needlestick and sharp instruments have high frequency and involve mainly female students. They are more common in the afternoon and in the clinical setting and the time interval was between exposure and the search for care complied with recommendations of the Brazilian legislation.

    The imposex incidence was appraised in South American gastropods, considering the scenario before and after the global ban of tributyltin (TBT). A statistically significant reduction in imposex indexes was observed in Stramonita haemastoma collected in 2006 and 2010 from areas under the influence of four coastal harbors from southern Brazil. This reduction may be because of the effectiveness of the global ban issued by the International Maritime Organization, although the restrictions on TBT-based antifouling paints in Brazil might also have helped. Even so, a residual organotin contamination was still detected in female tissues (levels ranged from 7.6 to 164.9 ng Sn/g for TBT; from imposex and environmental levels of organotins is expected in every ocean worldwide soon after the implementation of national and international restriction regulations, this will depend on the effectiveness of the global TBT ban; the effectiveness of local restrictions on producing, selling, and using TBT-based antifouling paints; and specific characteristics of local sediments, because metabolization rates and sorption/desorption of TBT previously deposited might affect its environmental bioavailability. Therefore, the reduction trend detected in the present study cannot be extrapolated to other Brazilian or South American coastal areas. Copyright © 2012 SETAC.

    Full Text Available Currency notes have been implicated as a vehicle for transmitting community-acquired bacterial infections. However, the overall diversity of the bacterial population residing on banknotes is still unknown in Brazil. In this study, we aimed to investigate the overall bacterial population from 150 different Brazilian Rial (R$ notes in circulation using a culture-independent Illumina massively parallel sequencing approach of the 16S rRNA genes. Samples were randomly collected from three different street markets or “feiras” in the metropolitan region of São Paulo. Taxonomical composition revealed the abundance of Proteobacteria phyla, followed by Firmicutes and Streptophyta, with a total of 1193 bacterial families and 3310 bacterial genera. Most of these bacterial genera are of human, animal, and environmental origins. Also, our analysis revealed the presence of some potential pathogenic bacterial genera including Salmonella, Staphylococcus, and Klebsiella. The results demonstrate that there is a tremendous diversity of bacterial contamination on currency notes, including organisms known to be opportunistic pathogens. One of the factors that may contribute to the richness of bacterial diversity in currency notes is personal hygiene. Thus, our results underscore the need to increase public awareness of the importance of personal hygiene of money handlers who also handle food.

  6. False Shades of Green: The Case of Brazilian Amazonian Hydropower

    Full Text Available The Federal Government of Brazil has ambitious plans to build a system of 58 additional hydroelectric dams in the Brazilian Amazon, with Hundreds of additional dams planned for other countries in the watershed. Although hydropower is often billed as clean energy, we argue that the environmental impacts of this project are likely to be large, and will result in substantial loss of biodiversity, as well as changes in the flows of ecological services. Moreover, the projects will generate significant greenhouse gas emissions from deforestation and decay of organic matter in the reservoirs. These emissions are equivalent to the five years of emissions that would be generated by gas powered plants of equivalent capacity. In addition, we examine the economic benefits of the hydropower in comparison to new alternatives, such as photovoltaic energy and wind power. We find that current costs of hydropower exceed alternatives, and the costs of costs of these alternatives are likely to fall substantially below those of hydropower, while the environmental damages from the dams will be extensive and irreversible.

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

    Bibliographic references of scientific articles are the source for calculating impact indexes frequently used for the assignment of funding to research projects. Different citation patterns may result in measurement bias of these impact indexes. To analyze citation patterns of Brazilian and Portuguese biomedical journals regarding the geographic origin of the sources cited. As part of the v+biomed project, a convenience sample of 11 biomedical journals, 4 Portuguese and 7 Brazilian, was gathered including the following subject categories: General and Internal Medicine, Public Health, Gynecology and Obstetrics, and Surgery. All the references from all the articles published in all the issues (except supplements) in 2009 and 2010 were retrieved. The type of source cited and its geographic origin were analyzed. A total of 102 issues from the 11 journals, containing 1430 articles, with a total of 32782 references were analyzed. No differences were found regarding the number of authors, pages or references between articles from Brazilian and Portuguese journals. Brazilian journals presented higher prevalence of English language and cited significantly more journals from their own country (30.1%) comparing to Portuguese journals (5.4%). Additionally, a lower citation rate to journals from the other country analyzed was evident in Brazilian (0.1%) when compared to Portuguese (3.2%) journals, as well as a higher self-citation of Brazilian journals (Brazil - 5.6%, Portugal - 2.1%). A different citation pattern between Portuguese and Brazilian biomedical journals was found, consisting of a higher citation rate from Brazilian to other Brazilian journals and to themselves. This differential in citation patterns may have implications on impact indexes determination which warrant further investigation.

    2014-01-01

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

    Bioethanol from sugarcane is increasingly seen as a sustainable alternative energy source. Besides having high photosynthetic efficiency, sugarcane is a perennial tropical grass crop that can re-grow up to five or more years after being planted. Brazil is the largest producer of sugarcane in the world and management practices commonly used in the country lead to lower rates of inorganic N fertilizer application than sugarcane grown elsewhere, or in comparison to other feedstocks such as corn. Therefore, Brazilian sugarcane ethanol potentially promotes greenhouse gas savings. For that reason, several recent studies have attempted to assess emissions of greenhouse gases (GHG) during sugarcane production in the tropics. However, estimates have been mainly based on models due to a general lack of field data. In this study, we present data from in situ experiments on emission of three GHG (CO2, N2O, and CH4) in sugarcane fields in Brazil. Emissions are provided for sugarcane in different phases of the crop life cycle and under different management practices. Our results show that the use of nitrogen fertilizer in sugarcane crops resulted in an emission factor for N2O similar to those predicted by IPCC (1%), ranging from 0.59% in ratoon cane to 1.11% in plant cane. However, when vinasse was applied in addition to mineralN fertilizer, emissions of GHG increased in comparison to those from the use of mineral N fertilizer alone. Emissions increased significantly when experiments mimicked the accumulation of cane trash on the soil surface with 14 tons ha-1and 21 tons ha-1, which emission factor were 1.89% and 3.03%, respectively. This study is representative of Brazilian sugarcane systems under specific conditions for key factors affecting GHG emissions from soils. Nevertheless, the data provided will improve estimates of GHG from Brazilian sugarcane, and efforts to assess sugarcane ethanol sustainability and energy balance.

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

    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...

    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.

    2012-07-01

    Full Text Available Technological capabilities (TC play a key role in the competitiveness of firms in industrial sectors. Suppliers in emerging economies often acquire technological capabilities by operating and mastering technologies developed by others and then leveraging this learning to develop indigenous technologies. By reviewing research on firm specific technological capabilities, the development of global value chains and industrial clusters in emerging markets we discuss local suppliers’ insertion and upgrading in the supply chains of new large industrial enterprises. Using the Brazilian shipbuilding industry as context, we investigate and develop propositions related to the ability of local suppliers to develop technological capabilities that permit eventual insertion into the local supply chain. This research has applications for managers and policy makers from other emerging market countries seeking to increase local sourcing through development of local suppliers.

  4. The multiplicity of Brazilian Social Psychology

    Mariana Prioli Cordeiro

    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.

    Letícia P D Mortoza

    Full Text Available Capital flows are responsible for a strong influence on the foreign exchange rates and stock prices macroeconomic parameters. In volatile economies, capital flows can change due to several types of social, political and economic events, provoking oscillations on these parameters, which are recognized as economic crises. This work aims to investigate how these two macroeconomic variables are related with crisis events by using the traditional complex measures due to Lopez-Mancini-Calbet (LMC and to Shiner-Davison-Landsberg (SDL, that can be applied to any temporal series. Here, Ibovespa (Bovespa Stock Exchange main Index and the "dollar-real" parity are the background for calculating the LMC and SDL complexity measures. By analyzing the temporal evolution of these measures, it is shown that they might be related to important events that occurred in the Brazilian economy.

  6. Equity Market Timing: Testing Using Brazilian IPOs

    José Luiz Rossi Jr

    2010-04-01

    Full Text Available This paper analyzes whether the behavior related to the equity market timing affected the recent IPO wave of Brazilian firms and exerted an impact on companies'capital structure. Using data from january 2004 to december 2007 the paper classifies the months in the sample in hot or cold according the number of IPOs that took place in each month. The paper confirms an oportunistic behavior by the firms that issue a higher volume of stocks in periods classified as hot. The paper also shows that the impact of this behavior on companies` capital structure is very limited. Although there is a reduction in companies` leverage right after the IPO, this returns to its previous level only a few quarters after the IPO.

    Martins, Gabriela C; Ribeiro, Fabiano L; Forgerini, Fabricio L

    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...

  9. Critical journalism: the progressive” Brazilian bloggers case

    2013-12-01

    Full Text Available This paper aims at understanding what comprises the professional identity of a well-known group of experienced Brazilian journalists who, at the same time, express their political opinion in independent blogs and define themselves as “progressive” or “dirty”. Our objective is to understand how these bloggers define and practice journalism in their blogs and how they view their work in a democratic context. Through various interviews, we mapped out their main journalistic values and described their professional identity as blogger journalists who advocate critical journalism, in other words, opinionated journalism. The results showed that these journalists consider their blogs to be a place for a wide range of opinions against traditional media, and that their main job as online journalists is to be vigilant in relation to political powers, including the media which is seen as an important and relevant political actor in Brazil.

  10. Brazilian environmental sociology: a provisional review

    Directory of Open Access Journals (Sweden)

    Ferreira Leila da Costa

    2002-01-01

    Full Text Available The article aims firstly at the reconstitution and analysis of history within the scope of international environmental sociology situated in the context of contemporary sociology. It also discusses - from the standpoint of literature (Buttel, Dunlap, Hanning, among others - its theoretical-methodological and institutional aspects as well in order to understand the obstacles encountered to legitimate and consolidate a set of problems which, until recently, were not dealt with by social sciences. Secondly, it analyses the Brazilian case. Environmental sociology in Brazil is strongly influenced by American empirical sociology, the precursor of the institutionalization process for the themes. On the other hand, further analysis of this case is relevant to understand the relationship between the scientific sphere, and the creation of environmental policies and social movements.

  11. The Brazilian business and growth cycles

    2002-03-01

    Full Text Available This paper uses several produceres to date and analyse the Brazilian business and growth cycles. In particular, a Markov switching model is fitted to quarterly and annual real production data. The smoothed probabilities of the Markov states are used as predictive rules to define different phases of cyclical fluctuations of real Brazilian production. The results are compared with different non-parametric rules. All methods implemented yield similar dating and reveal asymmetries across the different states of the Brazilian business and growth cycles, in which slowdowns and recessions are short and abrupt, while high growth phases and expansions are longer and less steep. The resulting dating of the Brazilian economic cycles can be used as a reference point for construction and evaluation of the predictive performance of coincident, leading, or lagging indicators of economic activity. In addition, the filtered probabilities obtained from the Markov switching model allow early recognition of the transition to a new business cycle phase, wich can be used, for example, for evaluation of the adequate strength and timing of countercyclical policies, for reassessment of projected sales or profits by businesses and investors, or for monitoring of inflation pressures.Este artigo utiliza vários métodos para datar e analisar ciclos de negócios e de crescimento no Brasil. Em particular, um modelo de mudanças de Markov é aplicado a dados de produção trimestrais e anuais. As probabilidades suavizadas dos estado markovianos são utilizadas como regras de previsão para definir as diferentes fases de flutuações cíclicas na produção real brasileira. Os resultados são comparados com diferentes regras não-paramétricas. Todos os métodos implementados geram uma cronologia similar e revelam assimetrias nas diferentes fases dos ciclos de negócio e crescimento do Brasil, nos quais os estados de baixo crescimento e recessão são de curta duração e mais

  12. Representation of differences in Brazilian journalistic discourse

    Fernando Resende

    2015-08-01

    Full Text Available Considering the technological advance, which enhances the production of mediatic discourses, and the notion of a libidinal power installed in our globalized societies, reflecting upon representation of differences seems to be a major issue. This essay discusses the production of journalistic discourses from an epistemological perspective. The field of media is taken as constituted by a triple component – discourse/narrative/machines – and we suggest that this triad has proved to be incomplete: discourse and narrative, once they really are vertexes of the triangle, are absences. Two journalistic-documentary productions – which intend to represent life in the slums of Brazil – are compared in order to reflect upon representation of differences in Brazilian journalistic discourse. In view of the up-to-date polarization and pulverization of discourses, we suggest that in the perspective of the journalistic discourse, one can only speak about alterity if one tries to comprehend the ways news is staged.

  13. Aging, Gender and Sexuality in Brazilian Society

    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.

    Padilha, Maria Itayra; Borenstein, Miriam Susskind; Carvalho, Maria Aline Lima; Ferreira, Aline Coelho

    2012-02-01

    The objective of this study is to examine the activities of Nursing History research groups in Brazil and their relationships with the nursing undergraduate and graduate courses. This exploratory, descriptive, qualitative documental study was performed from July 2008 to March 2010. We identified 34 research groups that had Nursing History as the focus of at least one of the lines of research. Results showed that the groups have produced a great amount of bibliographical material, research lines and broad participation of undergraduate and graduate students. It was also found that there is a communication network among groups working within the same line of research. In conclusion, there is a need to increase interdisciplinarity and also strengthen some lines of research in order to support knowledge of the history of Brazilian nursing.

    2009-01-01

    Full Text Available The aim of this study was to evaluate methods for developing a Brazilian maize core collection. For an initial survey of the active collection, passport information, as well as characterization and evaluation of accessions, were taken into consideration, these then being divided according to geographic region and kernel-type. Multiple sampling methods were evaluated. The strategy of constant sampling generated extensive alterations in extract accession frequency. The multivariate strategy with dispersion graphs and principal components associated with the Tocher method was considered efficient for identifying the most divergent genotypes. The multivariate strategy generated greater alterations in the variance of traits. The average number of traits revealed few modifications with the various sampling strategies used. Therefore, the active collection could be considered as possessing a satisfactory amount of information for most of its accessions. Moreover, the multivariate strategy generated modifications in the variance of the traits, independent of sampling intensity.

    Full Text Available Five out of the seven recognized species of sea turtles (Testudines occur on the Brazilian coast. The Barcode Initiative is an effort to undertake a molecular inventory of Earth biodiversity. Cytochrome Oxidase c subunit I (COI molecular tags for sea turtle species have not yet been described. In this study, COI sequences for the five species of sea turtles that occur in Brazil were generated. These presented widely divergent haplotypes. All observed values were on the same range as those already described for other animal groups: the overall mean distance was 8.2%, the mean distance between families (Dermochelyidae and Cheloniidae 11.7%, the mean intraspecific divergence 0.34%, and the mean distance within Cheloniidae 6.4%, this being 19-fold higher than the mean divergence observed within species. We obtained species-specific COI barcode tags that can be used for identifying each of the marine turtle species studied.

The literature search was carried out in the electronic databases Pubmed and Bireme, using the keywords: obesity, overweight, BMI, adolescents and Brazil. The following inclusion criteria were considered: Brazilian adolescents, BMI-based obesity estimates, publication until 2007, and adequate methodology. After the examination of titles, abstracts and full texts, 27 papers fulfilled our inclusion criteria. For describing the studies, the following variables were used: type of survey, design, age range, sample size, place of data collection. For evaluating the evidence, the following indicators were used: methods used, independent variables studied, statistical analyses employed, and cut-off used for defining obesity. Most studies used cross-sectional designs (77.7% and were carried out through home interviews (51.7%. Only one study used a nationally-based sample and three used regional-based samples (Northeast and Southeast. Regardless the design, place, type of survey, age range and cut-off used, the prevalence of obesity tended to be higher in the following groups: adolescents living in the Southeast region, living in urban areas, from high socioeconomic level and from private schools. In terms of behavioral determinants of obesity, the paucity of prospective studies and the difficulties of adequately measuring physical activity and food consumption, make the results less clear. Although the number of studies has increased, it is still necessary to stimulate surveys in the North, Southeast and Mideast regions. Prospective studies are also necessary, in order to evaluate the association between obesity and behavioral exposures.

    2015-09-01

    Full Text Available 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.

    The goal of this paper is to assess the frequency of depression symptoms among Brazilian immigrants living in Massachusetts, the second largest Brazilian immigrant population in the United States, and to identify correlates of depression. A convenience sample of Brazilian immigrants aged 18 or older residing in Massachusetts was used. Data were collected from December 2013 to March 2014, in the Consulate General of Brazil in Boston and in three religious events, using a structure questionnaire and the Center for Epidemiological Studies Depression Scale (CES-D). Depression symptoms were observed in 35.3% of the respondents, with equal distribution by sex. Correlates of depression were low income, being single, poor English proficiency, and poor self-perception of health. These results suggest a need for community outreach, sensitization, and counseling, in Portuguese and adapted to the culture of Brazilian immigrants.

    This paper explores how prevalent contemporary problematizations of organizations coincide with a widespread assessment that Organization Studies (OS) has run out of steam. This impasse, the paper argues, is largely due to the emergence of an organization-phobia that has come to seize several...... strands of theorizing. By attending to the wide-ranging and far-reaching history of this organization-phobia, the paper argues that OS has become increasingly incapable of speaking about its core object. I show how organizations went from being conceptualized as entities of major importance to becoming...... credibility and legitimacy to begin with, the organization-phobia resulting from this history has been implicated in dismantling organizations, and in making OS progressively irrelevant to a wider public....

  10. Consensus of the Brazilian Society of Infectious Diseases and Brazilian Society of Clinical Oncology on the management and treatment of Kaposi's sarcoma

    Directory of Open Access Journals (Sweden)

    Érico Arruda

    Full Text Available Kaposi's sarcoma is a multifocal vascular lesion of low-grade potential that is most often present in mucocutaneous sites and usually also affects lymph nodes and visceral organs. The condition may manifest through purplish lesions, flat or raised with an irregular shape, gastrointestinal bleeding due to lesions located in the digestive system, and dyspnea and hemoptysis associated with pulmonary lesions. In the early 1980s, the appearance of several cases of Kaposi's sarcoma in homosexual men was the first alarm about a newly identified epidemic, acquired immunodeficiency syndrome. In 1994, it was finally demonstrated that the presence of a herpes virus associated with Kaposi's sarcoma called HHV-8 or Kaposi's sarcoma herpes virus and its genetic sequence was rapidly deciphered. The prevalence of this virus is very high (about 50% in some African populations, but stands between 2% and 8% for the entire world population. Kaposi's sarcoma only develops when the immune system is depressed, as in acquired immunodeficiency syndrome, which appears to be associated with a specific variant of the Kaposi's sarcoma herpes virus. There are no treatment guidelines for Kaposi's sarcoma established in Brazil, and thus the Brazilian Society of Clinical Oncology and the Brazilian Society of Infectious Diseases developed the treatment consensus presented here.

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

    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®.

    The shortage of organs has made it necessary to search for new alternatives such as xenotransplantation. However, the use of animal organs could be opposed by society and the personnel involved in its implementation. This study aimed to analyze the attitude of veterinary degree students in a Brazilian university towards xenotransplantation, to determine factors that affect its acceptance, and to compare the attitudes among a control group of veterinary degree students in a Spanish university. Of the 422 students registered for a veterinary course from 2010 to 2011, 374 were surveyed with a questionnaire completion rate of 89%. Attitudes were evaluated using a validated questionnaire that was self-administered administered anonymously. The process was coordinated by an independent health care worker. We applied the student t and the chi-squared-tests for statistical analysis. If xenotransplantation was confirmed as a clinical reality, 90% (n = 338) of Brazilian students would accept the use of a xenotransplanted organ; 94% (n = 350), tissue; and 97% (n = 360), cell xenotransplantation. Attitudes toward xenotransplantation were not determined by the academic year, any psychosocial variable, or attitudes toward deceased human organ donation (P = .167). However, the attitudes would be affected by a belief that the transplanted animal organ would not change anything (P = .001). Interaction with other people was also related to more favorable attitudes (P = .015). Subjects who expressed a more favorable attitude tended to more readily accept cell (P = .000) or tissue xenotransplantation (P = .000). In Spain (control group), the results were similar: 91% (n = 436) would accept a xenotransplantation; 95% (n = 457) tissue; and 97% (n = 467), cell xenotransplantation. Also, this attitude was not affected by the academic year, any psychosocial variable, or attitude toward organ donation (P = .779). Both Brazilian and Spanish veterinary students had favorable attitudes toward

The initiative called "Allergic Rhinitis and its Impact on Asthma", initially published in 2001 and updated in 2008 and 2010, has been very successful in disseminating information and evidence, as well as providing a classification of severity and proposing a systemized treatment protocol. In order to include the participation of other medical professionals in the treatment of allergic rhinitis, it is important to develop algorithms that accurately indicate what should and can be done regionally. To update the III Brazilian Consensus on Rhinitis - 2012, with the creation of an algorithm for allergic rhinitis management. We invited 24 experts nominated by the Brazilian Association of Allergy and Immunology, Brazilian Association of Otorhinolaryngology and Head and Neck Surgery and Brazilian Society of Pediatrics to update the 2012 document. The update of the last Brazilian Consensus on Rhinitis incorporated and adapted the relevant information published in all "Allergic Rhinitis and its Impact on Asthma" Initiative documents to the Brazilian scenario, bringing new concepts such as local allergic rhinitis, new drugs and treatment evaluation methods. A flowchart for allergic rhinitis treatment has been proposed. Copyright © 2017. Published by Elsevier Editora Ltda.

    To assess whether there is a preference for international journal citation to the detriment of national ones in ten Brazilian medical journals, in two different periods. All references in the articles published in Arquivos Brasileiros de Oftalmologia, Revista Brasileira de Cirurgia Cardiovascular, Revista da Associação Médica Brasileira, São Paulo Medical Journal, Arquivos Brasileiros de Endocrinologia e Metabologia, Clinics, Jornal Brasileiro de Pneumologia, Revista da Sociedade Brasileira de Medicina Tropical, Revista Brasileira de Psiquiatria e Acta Ortopédica Brasileira in the years 2011 and 2007 were analyzed, assessing the number of articles published in national and international journals. A total of 36,125 references from 1,462 articles published in the 10 aforementioned journals were analyzed. Of the total number, 4.242 (11.74%) were from Brazilian journals. There was no significant difference between the two analyzed periods. A total of 453 (30,98%) of the articles studied non-cited brazilian papers,and 81 (5.54%) articles had more Brazilian than international references. Of total references analyzed, 11.74% were related to articles published in Brazilian journals. This number, when compared to the percentage of Brazilian articles published in the medical area, demonstrates a good number of citations of national articles. Copyright © 2012 Elsevier Editora Ltda.

    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.

  4. Brazilian contribution for a better knowledge on the biology of Toxoplasma gondii

    Full Text Available Historically, scientists in Brazil has significantly contributed to the biology, cultivation and structural organization of the pathogenic protozoan Toxoplasma gondiiand its interaction with host cells, starting with the description of the protozoan by Splendore in 1908. The intracellular and extracellular corpuscoli observed in rabbits, corresponded to what we now as tachyzoites. Later on, a pioneering method to grow T. gondii in tissue cultures was developed by Guimarães and Meyer, 1942. They also observed for the first time T. gondii by transmission electron microscopy and made the initial description of the cytoskeleton of T. gondii by observing negatively stained cells. In the 1980's, the relation of the cytoskeleton with the sub-pellicular microtubules was reveled by freeze-fracture. More recently, several Brazilian groups have analyzed in detail basic aspects of the early interaction of the protozoan with the host cell, such as the role of protein phosphorylation, transfer of host cell surface components to the protozoan and genesis and organization of the parasitophorous vacuole. Tachyzoites strategically inhibit nitric oxide production during active invasion of activated macrophages. In vitro studies on the sexual cycle of T. gondii using primary cultures of cat enterocytes and the egress from host cells are being carried out. Perspectives are that the contribution of Brazilian science to the knowledge on T. gondii biology will continue to flourish in years to come.

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

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

    Full Text Available In this paper we investigate the relationship between youth prolongation in Brazilian and Spanish youngsters and the identity construction processes of these individuals. We conducted semi-structured interviews with 50 young men and women aged 25 to 29 years, half of them from Madrid/Spain and the other half from Fortaleza/Brazil. The interviews were recorded and transcribed, the speeches were organized with the Atlas-ti program through a semantic content analysis. We assume that the postponement of the thresholds of transition to adulthood leads to new experiences, discourses and meanings of "being young", creating a new ideal-typical model of "prolonged youth" and turning it into a possibility of identification for a significant group of young people. In Spain, the youth prolongation is a much more pronounced and evident phenomenon than in Brazil. However, the movement towards a youth prolongation, especially concerning the "feeling younger for longer" is also a trend among young Brazilians.

    ABSTRACT 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

    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

    The Brazilian semiarid sub region is located in the Northeast and a small part of the territory of the Southeast region of Brazil. The study area lies between latitudes 3º to 18º S and between longitudes 35° to 46° W. According to the Köppen classification, semi-arid climate BSh and BSk is dominated, and the mean annual temperatures is between 26 and 28 ºC. In total nine units are incorporated in the federation, eight Northeast and a small portion of the southeast region. The land area is 982,563.3 km² with 22,598,318 inhabitants residents, nearly 12% of the national population, divided into 1,133 municipalities. The sub region has population density of 23.06 inhabitants per km2. Northeast Brazil is characterized by precipitation variability and irregularity in its spatiotemporal distribution, which make it to be under a severe water shortage. This study is aimed to analyze the rainfall variability through anomalies for El Niño and La Niña years (severe, moderate and weak), calculation the values of the Concentration Index, and numbers of irregular rainy days. The first part is concerning in analyzing the consistency and standardization of rainfall, using R-Package CLIMATOL. The work was achieved using daily rainfall data, during the period 1970-2012, based on the 104 series long enough rainfall observatories in the Brazilian semiarid region. Study of daily rainfall events, may contribute in improving land use and regional economic development, based on the water, the source of life of living beings. Results show rainfall anomalies, especially in the strong El Niño years, such as 1983 and 1992, a large variability appears in precipitation semiarid region, especially in the northern part. This study also shows a sever precipitation variability between years. The semiarid area has years of drought and years with rainfall above the climatological average normal. The stronger are the events, the more erratic rainfall, ie intense El Niño events cause intense

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

  14. The use of commas and prosody of Brazilian Portuguese: analytical- theoretical aspects and didactic implications

    Directory of Open Access Journals (Sweden)

    Geovana Soncin

    2015-02-01

    Full Text Available In this paper, we establish relations between the uses of comma in texts written by students from the year of Middle School and the prosodic organization of Brazilian Portuguese. Even though commas usage convention is primarily syntax-based, we argue that the uses of commas in texts have prosodic regularities that, simultaneously, organize the segmentation of utterances and contribute to the constitution of sense in texts. On the one hand, we argue that prosody is a signifying structure in writing and, thus, it is not a particularity of speech. On the other hand, we defend that the uses of commas, by establishing the prosodic structure of language in writing, do reference, by a symbolic process, the way prosodic phenomena produce sense in different utterances within oral practices. As a possible application of the theoretical discussion, we propose to recognize the complexity of commas usage as a more interesting practice at school than considering its so-called syntactic homogeneity.

    The present study evaluates how five sectors of two Brazilian hospitals have implemented lean healthcare concepts in their operations. The main characteristics of the implementation process are analyzed in the present study: the motivational factor for implementation, implementation time, form (consultancy or internal), team (hospital and consultants), lean implementation continuity/sustainability, lean healthcare tools and methods implemented, problems/improvement opportunities, lean healthcare barriers faced during the implementation process, and critical factors that affected the implementation and the results obtained in each case. The case studies indicate that reducing patient lead times and costs and making financial improvements were the primary factors that motivated lean healthcare implementation in the hospitals studied. Several tools and methods were used in the cases studied, especially value stream mapping and DMAIC. The barriers found in both hospitals are primarily associated with the human factor. Additionally, the results obtained after implementation were analyzed and improvements in financial aspects, productivity and capacity, and lead time reduction of the analyzed sectors were observed. Further, this study also exhibited four propositions elaborated from the results obtained from the cases that highlighted barriers and challenges to lean healthcare implementation in developing countries. Two of these barriers are hospital organizational structure (and, consequently, how the senior management works with medical staff), and outsourcing hospital activities. This study also concluded that the initialization and maintenance of lean healthcare implementation rely heavily on external support because lean healthcare subject knowledge is not yet available in the healthcare organization, which represents a challenge.

    Brazil is one of the leading countries in the use of renewable energy. Most of its electricity comes from hydro power, about 200,000 barrels a day of ethanol from sugar cane is used as fuel, around 38% of the pig iron, and 20% of the steel production, uses charcoal as a reducing medium. Located in the tropics, with the sun shining all year round, and with its vast territory, the Country may be regarded as having all the basic conditions to develop a modern Biomass for Electricity industry. The conjunction of those characteristics with, the necessity of developing new energy resources for electricity production in the Northeast of the Country, the results of the studies made by Princeton University, Shell and Chesf, the progress achieved by the BIG-GT (Biomass Integrated Gasification Gas Turbine) technology in Europe, and the organization of the Global Environment Facility (GEF), provided the unique opportunity for the implementation of a commercial demonstration in Brazil. This paper describes the idea, the scope, the technical challenges, and actual status of development of the WBP, a project which aims to demonstrate the commercial viability of the BIG-GT technology. It also highlights, the project management structure, the role of the GEF, World Bank and of the United Nations Development Program (UNDP), and the participation of the Brazilian Federal Government, through the Ministry of Science and Technology (MCT). Finally it describes the Participants (ELETROBRAS, CVRD, CIENTEC, SHELL, and CHESF), their role in the project, and how the group was formed and operates.

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

    In Brazil, although it is qualified as a major world producers, however, the production losses are high. Nevertheless, these losses can be reduced by processing the fruit 'unsuitable' for consumption into products based on green banana (pulp, rind and flour). The green banana flour shows enhanced nutrition value, with higher contents of mineral, dietary fiber, resistant starch, and total phenolics, for use in Brazilian irradiated ready - to eat foods, such as bread, macaroni, among others. Food irradiation has been identified as safe technology to reduce risk of foodborne illness as part of high-quality food production, processing, handling and preparation. Food irradiation utilizes a source of ionizing energy that passes through food to destroy harmful bacteria and other organisms. Often referred to as 'cold pasteurization', food irradiation offers negligible loss of nutrients or sensory qualities in food as it does not substantially raise the temperature of the food during processing. The object of this work was to determine the effect of gamma irradiation on microbiological analyses of the: the number of mesophiles, total coliforms at 35 deg C, coliforms at 45 deg C, Staphylococcus aureus and Salmonella spp of the green banana flour, commercially found in the Brazilian market. The microbiological analyses were carried out in conformity with the methodologies described at the Faculty of Veterinary Medicine, according to the current legislation. Irradiation was performed in a {sup 60}Co Gammacell 220 (AECL) source, with dose of 3kGy at IPEN/CNEN-SP. In samples of Brazilian green banana flour, irradiated at 3 kGy, the growth of all microorganisms (mesophiles, total coliforms at 35 deg C, coliform at 45 deg C and Staphylococcus coagulase positive) were reduced. As a result, the application of the irradiation technique may be recommended to enhance the food safety. (author)

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

    OBJECTIVE To analyze temporal trends of the prevalence of alcohol and tobacco use among Brazilian students. METHODS We analyzed data published between 1989 and 2010 from five epidemiological surveys on students from the 6th to the 12th grade of public schools from the ten largest state capitals of Brazil. The total sample consisted of 104,104 students and data were collected in classrooms. The same collection tool – a World Health Organization self-reporting questionnaire – and sampling and weighting procedures were used in the five surveys. The Chi-square test for trend was used to compare the prevalence from different years. RESULTS The prevalence of alcohol and tobacco use varied among the years and cities studied. Alcohol consumption decreased in the 10 state capitals (p < 0.001) throughout 21 years. Tobacco use also decreased significantly in eight cities (p < 0.001). The highest prevalence of alcohol use was found in the Southeast region in 1993 (72.8%, in Belo Horizonte) and the lowest one in Belem (30.6%) in 2010. The highest past-year prevalence of tobacco use was found in the South region in 1997 (28.0%, in Curitiba) and the lowest one in the Southeast in 2010 (7.8%, in Sao Paulo). CONCLUSIONS The decreasing trend in the prevalence of tobacco and alcohol use among students detected all over the Country can be related to the successful and comprehensive Brazilian antitobacco and antialcohol policies. Despite these results, the past-year prevalence of alcohol consumption in the past year remained high in all Brazilian regions. PMID:26465662

    Full Text Available Abstract No Brazilian version of a specific scale for evaluating apathy in dementia is available. Objectives: To introduce a translated version of the Apathy Scale (AS for use with caregivers. Methods: The instrument was formally translated and then administered to the caregivers of a small sample of dementia patients, in order to assess scale comprehensibility and make final adjustments. The scale was subsequently administered to the caregivers of a second, independent sample of Alzheimer's disease (AD patients. The content validity of the scale was tested by correlating the AS scores with the Neuropsychiatric Inventory (NPI - apathy sub-score and Disability Assessment in Dementia (DAD total scores. Results: The first sample consisted of eleven subjects with dementia, most of whom had AD. The second sample comprised twenty patients with probable or possible AD (10 with mild dementia, a mean age of 84.1±5.8 years, and 2.2±1.6 years of schooling. The AS scores correlated with both NPI-apathy sub-score (r=0.756, p=0.001 and DAD total scores (r=-0.793, p=0.0005. Conclusions: The final version had good comprehensibility and correlated strongly with standardized apathy and functional activities of daily living measures.

    Full Text Available The exuberance of Brazilian flora has caused admiration since the arrival of the first navigators. Fifteen to twenty percent of plant species estimated for the planet are found in this country. Plant genetic resources are part of biodiversity with potential for use by human populations, and are linked to the culture of the people, establishing the traditional use or enabling an innovative use. In Brazil, the landscape architect Roberto Burle Marx was a pioneer in collecting, using, valuing and preserving native species that have been admired since the 16th century, although they were neglected in the following centuries due to the valuation of ornamental plants from Europe. Between 1930 and 1960, he carried out landscaping projects that became emblematic for the development of landscaping in the 20th century. The analysis of the trajectory of the landscape architect, the 22 projects he carried out during that period, as well as the genebank structured by him, reveal significant numbers in terms of conservation.

    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.

    Here, we describe the percentage of non-citation in Brazilian public health journals, a field that, until now, had not been investigated nationally or internationally. We analyzed articles, published between 2008 and 2012, of eight public health journals indexed in the scopus database. The percentage of non-citation differs between journals (from 5.7% to 58.1%). We identified four statistically distinct groups: História, Ciência, Saúde - Manguinhos (58% uncited articles); Physis: Revista de Saúde Coletiva, Interface, and Saúde e Sociedade (32% to 37%); Ciência & Saúde Coletiva and Revista Brasileira de Epidemiologia (16% to 17%); and Cadernos de Saúde Pública and Revista de Saúde Pública (6%). The non-citation in the first three years post-publication also varies according to journal. Four journals have shown a clear decline of non-citation: Cadernos de Saúde Pública, Ciência & Saúde Coletiva, Revista Brasileira de Epidemiologia, and Physis. Another three (Revista de Saúde Pública, Saúde e Sociedade, and Interface) presented an oscillation in non-citation, but the rates of 2008 and 2012 are similar, with different magnitudes. In turn, the journal História, Ciência, Saúde - Manguinhos maintains high rates of non-citation. Multidisciplinary journals attract more citation, but a comprehensive citation model still needs to be formulated and tested.

    Full Text Available ABSTRACT Objective: To investigate the prevalence and establish the profile of the consumption of dietary supplements among Brazilian athletes. Methods: A total of 182 athletes of both genders from 20 different sports participated in this study. The athletes answered a questionnaire containing sociodemographic and sports-related questions and were interviewed about the consumption of dietary supplements. Results: Forty seven percent of athletes reported having consumed at least one type of dietary supplement and 38% said they use more than three different types of supplements concurrently. Whey protein was the most commonly consumed supplement, and the most frequently mentioned reason for its consumption was performance improvement. The main source of information was coaches, and individual sport athletes were the greatest consumers and the most likely to seek dietary supplement. Conclusion: Approximately half of the participants used dietary supplements, which on most occasions were recommended by coaches. The consumption profile also revealed multiple supplementation practice and showed that nutrition education is essential for this specific population.

    Full Text Available BRCA1 mutations are known to be responsible for the majority of hereditary breast and ovarian cancers in women with early onset and a family history of the disease. In this paper we present a mutational survey conducted in 47 Brazilian patients with breast/ovarian cancer, selected based on age at diagnosis, family history, tumor laterality, and presence of breast cancer in male patients. All 22 coding exons and intron-exon junctions were sequenced. Constitutional mutations were found in seven families, consisting of one insertion (insC5382 in exon 20 (four patients, one four base-pair deletion (3450-3453delCAAG in exon 11 resulting in a premature stop codon (one patient, one transition (IVS17+2T> C in intron 17 affecting a mRNA splicing site (one patient, and a C> T transition resulting in a stop-codon (Q1135X in exon 11 (one patient. The identification of these mutations which are associated to hereditary breast and ovarian cancers will contribute to the characterization of the mutational spectrum of BRCA1 and to the improvement of genetic counseling for familial breast/ovarian cancer patients in Brazil.

The main goal was to identify the financial key performance indicators, so that it could contribute to a better comprehension about how the resorts area acts in Brazil. To achieve this goal, this study took researches which generated numbers and indicators that could establish a comparison between 2013 and 2014. The main sources were token from all resorts from the Associação Brasileira de Resorts - Resorts Brasil, as well as an interview with a renowned area professional. Other sources were token by the most important resorts books. There are actually 49 resorts which are part of the Brazilian Resorts Association-ABR/Resorts Brasil. This institution allowed the access to all its database, in which the associated resorts give numerical informations about its own performance. The resorts studied in this article were divided and studied in four big groups. The results showed that the national resorts market keeps increasing its statistics and improving its internal management processes and sales distribution. Revenues increased 6.34% in the main analysed indicator during the years of 2013 and 2014. It was also observed that beach and all inclusive resorts tend to have better results.

    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 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.

    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.

    The increase of the percentage of elderly population in Brazil and the increase in longevity incite a demand for information on the quantity of years spent in good health. The aim of the present study is to measure the life expectancy for the elderly of 60 years and above, by sex and age, in the year of 2003. The Sullivan method was used, which combined the life-table with the current experience of mortality and the self-perceived health. The mortality information was obtained from the life tables published by the IBGE (Brazilian Institute of Geography and Statistics), 2003. The self-perceived health was used and it was dichotomized in good and bad. This information came from the National Research of Household Sample (PNAD), 2003. The results indicate that women live longer, but spend a higher number of years perceiving their health as bad, as compared to men. The results also highlights to the need of considering the differences between sexes in relation to the demand for health care. It is also important to consider the need to have policies designed to allow the increase in the number of years that the elderly can live in good health conditions.

    New scientific articles about tuberculosis (TB) are published daily worldwide. However, it is difficult for health care workers, overloaded with work, to stay abreast of the latest research findings and to discern which information can and should be used in their daily practice on assisting TB patients. The purpose of the III Brazilian Thoracic Association (BTA) Guidelines on TB is to critically review the most recent national and international scientific information on TB, presenting an updated text with the most current and useful tools against TB to health care workers in our country. The III BTA Guidelines on TB have been developed by the BTA Committee on TB and the TB Work Group, based on the text of the II BTA Guidelines on TB (2004). We reviewed the following databases: LILACS (SciELO) and PubMed (Medline). The level of evidence of the cited articles was determined, and 24 recommendations on TB have been evaluated, discussed by all of the members of the BTA Committee on TB and of the TB Work Group, and highlighted. The first version of the present Guidelines was posted on the BTA website and was available for public consultation for three weeks. Comments and critiques were evaluated. The level of scientific evidence of each reference was evaluated before its acceptance for use in the final text.

    Full Text Available The aim of this article is to highlight the importance of food in the rituals of African Brazilian Candomblé, as well as in its cosmovision (world view. A brief description of Candomblé’s historical trajectory is provided in order to show how food offerings became part of its rituals and how specific ingredients became symbolically significant in this belief system. According to the theories applied, it is possible that food has at least two functions in Candomblé: to materialize principles and also to work as a ritual language. To show the role of food in Candomblé the state of Bahia was taken as a case study – firstly because Candomblé started there and secondly because, as this article shows, the sacred foods of Candomblé are also consumed in everyday life, outside of religious situations, but just as importantly constituting a part of Bahian cultural identity. The dishes that feature in the ritualised meals and at the same time in Bahians’ everyday eating are described at the conclusion of the article, with a mention of their ingredients and to whom they are offered. The research sources included publications by Candomblé believers and scholars of religion, as well as cooks and journalists specialising in Bahian cuisine.

  18. Visual sonority in Brazilian Sign Language literature

    2017-03-01

    Full Text Available ABSTRACT The idea of sonority in sign languages was treated by Perlmutter (1992 as perceptibility, a property of a segment that uses movement rather than one in which the hands stay in the same position. Sandler (1993 states that the visual salience of movement in sign languages plays a role similar to sonority in spoken languages. For Brentari (1998, perceptually, a sign is visible from considerable distances, and measurement of its visual sonority is based on the joints involved in its production. This work focuses on visual sonority in literature in Brazilian Sign Language and considers the relevance of manual and non-manual elements, rhythm, symmetry, the scale of signs, and the effect of video on this concept. Two signed stories “The King’s Parrot” and “Little Ping Pong Ball” were analysed, highlighting specific signs in which the use of joints, non-manual features, and other resources are influenced by the size of the performance space and the distance of the audience from the signing. Three types of ‘sonority’ were observed: in the movement of the whole body on the stage, in the size of arms and trunk movement, and in the hands. In addition to the joints, non-manual features, rhythm and symmetry play an important role in visual sonority and influence the viewer’s experience.

    Full Text Available Background. High-quality clinical and genetic descriptions are crucial to improve knowledge of orofacial clefts and support specific healthcare polices. 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.

    The Idaho National Laboratory (INL) in collaboration with the U.S. Geological Survey (USGS) with the assistance of the Empresa de Pesquisa Energetica (EPE) and the Agencia Nacional de Energia Electrica (ANEEL) has performed a comprehensive assessment of the hydropower potential of all Brazilian natural streams. The methodology by which the assessment was performed is described. The results of the assessment are presented including an estimate of the hydropower potential for all of Brazil, and the spatial distribution of hydropower potential thus providing results on a state by state basis. The assessment results have been incorporated into a geographic information system (GIS) application for the Internet called the Virtual Hydropower Prospector do Brasil. VHP do Brasil displays potential hydropower sites on a map of Brazil in the context of topography and hydrography, existing power and transportation infrastructure, populated places and political boundaries, and land use. The features of the application, which includes tools for finding and selecting potential hydropower sites and other features and displaying their attributes, is fully described.

  1. DISPOSITION EFFECT AMONG BRAZILIAN EQUITY FUND MANAGERS

    2015-01-01

    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.

    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.

    Full Text Available Considering the technological advance, which enhances the
    production of mediatic discourses, and the notion of a libidinal power installed in our globalized societies, reflecting upon representation of differences seems to be a major issue. This essay discusses the production of journalistic discourses from an epistemological perspective. The field of media is taken as constituted by a triple component – discourse/narrative/machines – and we suggest that this triad has proved to be incomplete: discourse and narrative, once they really are vertexes of the triangle, are absences. Two journalistic-documentary productions – which intend to represent life in the slums of Brazil – are compared in order to reflect upon representation of differences in Brazilian journalistic discourse. In view of the up-to-date polarization and pulverization of discourses, we suggest that in the perspective of the journalistic discourse, one can only speak about alterity if one tries to comprehend the ways news is staged.

    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. Using various resources of the technique for the piano on the clusters and static movements, violent conflicts between the records of super acute and serious instrument, harpejos cross, etc . . .

    To evaluate whether there is a preference for foreign periodicals over Brazilian one. We evaluated all references of articles published in the years 2011 and 2007 in the journals Acta Cirúrgica Brasileira, Arquivos Brasileiros de Cirurgia Digestiva and the Journal of the Brazilian College of Surgeons, verifying the quantity of papers from Brazilian and foreign publications. We analyzed a total of 7,343 references arranged in 348 articles in those three journals; of these, 856 (11.65%) were from Brazilian journals. There was no difference between the three magazines, nor between the two periods. One hundred and eleven (31.9%) articles did not cite any Brazilian journal article and 36 (10.34%) cited Brazilian articles more than foreign ones. There is need for the Brazilian researcher to appreciate more the Brazilian journals, increasing citation from Brazil, without a scientific xenophobia.

    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

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

    Although Brazil is a megadiverse country and thus a conservation priority, no study has yet quantified conservation gaps in the Brazilian protected areas (PAs) using extensive empirical data. Here, we evaluate the degree of biodiversity protection and knowledge within all the Brazilian PAs through a gap analysis of vertebrate, arthropod and angiosperm occurrences and phylogenetic data. Our results show that the knowledge on biodiversity in most Brazilian PAs remain scant as 71% of PAs have less than 0.01 species records per km(2). Almost 55% of Brazilian species and about 40% of evolutionary lineages are not found in PAs, while most species have less than 30% of their geographic distribution within PAs. Moreover, the current PA network fails to protect the majority of endemic species. Most importantly, these results are similar for all taxonomic groups analysed here. The methods and results of our countrywide assessment are suggested to help design further inventories in order to map and secure the key biodiversity of the Brazilian PAs. In addition, our study illustrates the most common biodiversity knowledge shortfalls in the tropics.

    2009-09-01

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

    The 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.

    The Brazilian Health System has two different forms of access, public and private. The purpose of the public health system is to provide universal, complete access, free of charge, for the entire population. The private sector is composed by people who have private insurance. Nowadays, about 43 million Brazilians, or 26.3% of the population, have private health insurance. The main motivations of the physicians for the strike were the low payment for medical services and the constant interference of the private health insurance companies in medical autonomy. For this reason, Brazilian physicians held a 24-hour strike against the Medical Insurance Companies that did not accept to negotiate new fees in almost all Brazilian states. At least 120,000 physicians from all specialties stopped elective activities during that day, only providing urgent or emergency care. It is estimated that the strike affected 25 to 35 million Brazilians, about 76% of the total number of medical insurance users. Copyright © 2012 Elsevier Inc. All rights reserved.

    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.

    The World Health Organization's World Health Assembly WHA58.28/2005 Resolution recommends the adoption of e-health by health systems of State Members. The Brazilian Telehealth Program integrates the national policy of education for health that combines many strategies with complementary foci, including technical-level workers, undergraduate students of the 14 health professions, residency, postgraduate courses, support, and continuing health education at work. The Brazilian Unified Health System has approximately 1.5 million workers. The objectives of this work areas are as follows: to define a new concept, the so-called "formative second opinion" (FSO); to describe the methodology for its construction; and to show its structure as well as the number of FSOs already available, classified according to the field of knowledge. The Brazilian Telehealth Program was created in 2007 and has already offered around 41,000 teleconsultations. Based on their relevance and pertinence, 710 questions asked through teleconsulting by health professionals were selected. The questions were handled so that each question should not contain any specific information about patients, preserving professional confidentiality. For each question, a bibliographic review was performed and used to build a structured and standardized answer, based on the best available scientific and clinical evidence. This question-and-answer combination, originated thru teleconsulting, created by the Brazilian Telehealth Program, was termed the FSO and has been made available, with open access for all health professionals, at the Web site of the Program. Among the total number of 710 FSOs, diagnosis and treatment support corresponded to 238 questions (33.5%), followed by primary healthcare (90 questions) and then by subjects concerning oral health (68 questions) and nursery (39 questions). The structure and design of the FSO are also shown. The FSO helps professionals and health workers to use the already

    Twelve Lactobacillus isolates from Brazilian starter-free ovine cheeses were evaluated for their probiotic potential. The strains were identified by 16S rDNA sequencing as Lactobacillus plantarum (7), Lb. brevis (2), Lb. casei (2) and Lb. parabuchneri (1). All strains showed variable resistance to gastric juices and relative tolerance to pancreatin and bile salts. Only five strains of Lb. plantarum could not deconjugate the sodium salt of taurodeoxycholic acid. Autoaggregation ability after 24 h was above 50% and hydrophobicity was higher than 60% for most strains. All lactobacilli could inhibit linolenic acid oxidation, except Lb. parabuchneri strain, whereas none of them could scavenge DPPH radical. β-Galactosidase activity ranged from 47·7 to 2503 Miller units. Inhibition of food pathogens Listeria monocytogenes, Staphylococcus aureus, Bacillus cereus, Escherichia coli and Salmonella typhimurium was demonstrated and the production of organic acids could be associated with this effect. The Lactobacillus strains from Brazilian regional ovine cheese showed interesting functional characteristics, mainly the strains Lb. brevis SM-B and Lb. plantarum SM-I. Both presented high acid tolerance. In addition, Lb. brevis SM-B also displayed remarkable antioxidant activity and Lb. plantarum SM-I was the highest β-galactosidase producer, exhibited high autoaggregation and hydrophobicity properties.

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

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

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

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

In both samples, the PVQ-24 showed satisfactory internal consistency, and the proposed factor structure was confirmed (four systems: materialistic, religious, hedonistic, and post-materialist. The post-materialist system was organized into three subsystems: social well-being, individual well-being and occupational well-being. In both samples, confirmatory factor analysis and multidimensional scaling supported the hypotheses regarding content (four systems and three subsystems, structure (two dimensions and compatibility (positive correlations between systems.

  9. The relevance of the capital structure in firm performance: a multivariate analysis of Brazilian publicly traded companies

    Luiz Kennedy Cruz Machado

    2016-01-01

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

    Full Text Available 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 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.

    2015-06-01

    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.

  13. Systematic risk variations (beta convertible debenture brazilian companies

    2010-01-01

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

    Full Text Available Abstract Grape seed oil (GSO is an important by-product of the wine-making industry which has received attention as an alternative source of vegetable oils; its chemical compounds can be influenced by agricultural practices and industrial processing. Knowledge of the composition of Brazilian GSO is scarce; thus, this study aimed to analyze the chemical characteristics, as well as the antioxidant activity of these oils. GSO samples were obtained from Brazilian markets and showed significantly high amounts of phenolic, γ-tocotrienol and phytosterols as well as, the presence of several volatile compounds. Based on these results, is possible to show that oils exhibited good antioxidant activity. Therefore, it can be inferred that Brazilian GSO had a considerable content of phytochemical compounds with biological activity, which allows its association with other vegetable oils.

    Acácio T. C. Piedade

    2013-02-01

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

    2015-04-01

    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.

    Chagas disease is a neglected chronic condition with a high burden of morbidity and mortality. It has considerable psychological, social, and economic impacts. The disease represents a significant public health issue in Brazil, with different regional patterns. This document presents the evidence that resulted in the Brazilian Consensus on Chagas Disease. The objective was to review and standardize strategies for diagnosis, treatment, prevention, and control of Chagas disease in the country, based on the available scientific evidence. The consensus is based on the articulation and strategic contribution of renowned Brazilian experts with knowledge and experience on various aspects of the disease. It is the result of a close collaboration between the Brazilian Society of Tropical Medicine and the Ministry of Health. It is hoped that this document will strengthen the development of integrated actions against Chagas disease in the country, focusing on epidemiology, management, comprehensive care (including families and communities), communication, information, education, and research .

    The Test of Gross Motor Development (TGMD-2) is broadly used in research and clinical settings. The author aimed to translate and investigate the content, criteria, and construct validity and reliability of the TGMD-2 for Brazilian children. The study involved translators, experts, and 3,124 Brazilian children from several states of Brazil. Results confirmed language clarity and pertinence of the TGMD-2. Appropriate indices of the confirmatory factorial validity (root mean square error of approximation = .06; comparative fit index = .88; Tucker-Lewis index = .83; normed fit index = .09; goodness-of-fit index = .98; adjusted goodness-of-fit index = .95), test-retest (values from .83 to .91) and inter- and intrarater reliability were found. Concurrent validity between TGMD-2 and Movement Assessment Battery for Children was weak. The TGMD-2 is a validity and reliability instrument for Brazilian children.

    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

    2016-04-01

    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.

    Astrophysics and Space Science are becoming increasingly characterised by what is now known as “big data”, the bottlenecks for progress partly shifting from data acquisition to “data mining”. Truth is that the amount and rate of data accumulation in many fields already surpasses the local capabilities for its processing and exploitation, and the efficient conversion of scientific data into knowledge is everywhere a challenge. The result is that, to a large extent, isolated data archives risk being progressively likened to “data graveyards”, where the information stored is not reused for scientific work. Responsible and efficient use of these large data-sets means democratising access and extracting the most science possible from it, which in turn signifies improving data accessibility and integration. Improving data processing capabilities is another important issue specific to researchers and computer scientists of each field. The project presented here wishes to exploit the enormous potential opened up by information technology at our age to advance a model for a science data center in astronomy which aims to expand data accessibility and integration to the largest possible extent and with the greatest efficiency for scientific and educational use. Greater access to data means more people producing and benefiting from information, whereas larger integration of related data from different origins means a greater research potential and increased scientific impact. The project of the BSDC is preoccupied, primarily, with providing tools and solutions for the Brazilian astronomical community. It nevertheless capitalizes on extensive international experience, and is developed in full cooperation with the ASI Science Data Center (ASDC), from the Italian Space Agency, granting it an essential ingredient of internationalisation. The BSDC is Virtual Observatory-complient and part of the “Open Universe”, a global initiative built under the auspices of the

    Full Text Available Copy number alterations (CNA are one of the driving mechanisms of glioma tumorigenesis, and are currently used as important biomarkers in the routine setting. Therefore, we performed CNA profiling of 65 astrocytomas of distinct malignant grades (WHO grade I–IV of Brazilian origin, using array-CGH and microsatellite instability analysis (MSI, and investigated their correlation with TERT and IDH1 mutational status and clinico-pathological features. Furthermore, in silico analysis using the Oncomine database was performed to validate our findings and extend the findings to gene expression level. We found that the number of genomic alterations increases in accordance with glioma grade. In glioblastomas (GBM, the most common alterations were gene amplifications (PDGFRA, KIT, KDR, EGFR, and MET and deletions (CDKN2A and PTEN. Log-rank analysis correlated EGFR amplification and/or chr7 gain with better survival of the patients. MSI was observed in 11% of GBMs. A total of 69% of GBMs presented TERT mutation, whereas IDH1 mutation was most frequent in diffuse (85.7% and anaplastic (100% astrocytomas. The combination of 1p19q deletion and TERT and IDH1 mutational status separated tumor groups that showed distinct age of diagnosis and outcome. In silico validation pointed to less explored genes that may be worthy of future investigation, such as CDK2, DMRTA1, and MTAP. Herein, using an extensive integrated analysis, we indicated potentially important genes, not extensively studied in gliomas, that could be further explored to assess their biological and clinical impact in astrocytomas.

    2015-04-01

    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.

  8. Stylized Facts in Brazilian Vote Distributions.

    Directory of Open Access Journals (Sweden)

    Angelo Mondaini Calvão

    Full Text Available 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.

    2015-01-01

    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.

    The morphology of the spine is variable within a population, and its maintenance in appropriate values implies a decrease in the energy expended. We need to know their normal values in population. This study aims to carry out a literature review and evaluate published papers on spinopelvic parameters in a Brazilian population sample. Eleven potentially eligible papers were initially identified for inclusion in this review: three papers from PubMed and eight from Medicine. Out of these, only five papers contained methodology and relevant significance level, and therefore, they were included in the final analytical run. According to a Brazilian study, Pratali mentions no significant difference in the average values of spinopelvic balance in the Brazilian population and those found in the literature; there was also no significant difference comparing Brazilian and Korean population; however, a difference was found in comparison with European population regarding PI parameters and SS, but the latter with higher values. According to Kulcheski (Column/Columna 12:224-227, 2013), the values of pelvic tilt in the Brazilian population evaluated in his research were 19° (10°-35°) and the sacral inclination was 38° (30°-55°), presenting similar values concerning the European population. In another Brazilian paper, Oliveira (Rev Bras Ort 49:189-193, 2014) reports that the research population had PI average of 45° (41.9°-48.1°). The values obtained are relatively minor when compared to the European population. However, all of these are within the normal margin considered in the worldwide literature.

    University teaching hospitals usually provide tertiary care and are subject to early adoption of new technologies, which may compromise healthcare systems when uncritically adopted. Knowledge on the decision-making process - drug selection by drug selection committees or DTCs - is crucial to improve the quality of care. There are no models for studying the selection of drugs in Brazilian healthcare services. This study aims to discuss DTC structure and the processes regarding adoption of medicines in tertiary university hospitals in Brazil and to propose an analytical structure for providing direction for the future. State of the art content regarding drug selection processes and DTC procedures was reviewed in three databases. Information on the medicine selection process in a Brazilian gold standard teaching hospital was collected through observations and a review of existing procedures. A structured discussion on medicine selection and DTC procedures in tertiary hospitals ensued. This discussion resulted in findings that were organized in three dimensions, composing an analytical framework for the application in tertiary Brazilian hospitals (i) motivations for the adoption of drugs; (ii) necessary structural and organizational aspects for decision-making; and (iii) criteria and methods employed by the decision-making process. We believe that the suggested framework is compatible with tertiary Brazilian hospitals, because a gold standard in the country was able to conduct all its procedures in the light of WHO and international recommendations. We hope to contribute in producing knowledge which may hopefully be adopted in tertiary hospitals across Brazil. © 2014 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

    The Case Against Non-Compliance with the Fundamental Principle concerning Anencephaly, under review by the Brazilian Supreme Court, is a milestone in the debate on abortion in Latin America. Since the currently prevailing version of the Brazilian Penal Code was enacted in 1940, there has been fierce resistance to any change in the country's abortion policy. This article discusses the arguments and political strategies used in the anencephaly suit brought before the Supreme Court, particularly the ethical and legal position that interruption of pregnancy in cases of anencephaly does not constitute abortion, but should be considered a therapeutic anticipation of delivery.

    In Romania, the indebtedness level represented 39.6% of the GDP in 2014, in Brazil 57.19%. The Treaty of Maastricht in 1992, stipulated the limit of 60% of the GDP for the Euro Zone countries. Nevertheless the debt represented 91.9% of the GDP, especially due to Greece, Italy, Portugal, Spain and France. The Brazilian fiscal responsibility law has been developed from the experience of the tax laws of the United States and New Zealand . It is a reinterpretation of the applicable rules the Brazilian public debt compared with the limits set for the countries of the eurozone.

    This study compares energy conversion systems for the generation of electrical power, with an emphasis on the Brazilian energy matrix. The financial model applied in this comparison is based on the Portfolio Theory, developed by Harry Markowitz. The risk-return ratio related to the electrical generation mix predicted in the National Energy Plan - 2030, published in 2006 by the Brazilian Energy Research Office, is evaluated. The increase of non-traditional renewable energy in this expected electrical generating mix, specifically, residues of sugar cane plantations and wind energy, reduce not only the risk but also the average cost of the kilowatt-hour generated.

    Full Text Available This paper aims at analyzing the impacts of China’s rise on Latin American countries. The literature on the topic has stressed the emergence of an asymmetrical pattern of relationship, where the region would be trapped in a less dynamic status of producer and exporter of raw materials. We focus on identifying the post-global financial crisis trends, providing fresh evidence concerning the characteristics of Sino-Latin American economic relationships, emphasizing the Brazilian experience. Ours results suggest that, particularly in the Brazilian case, there is evidence of the emergence of an increasingly regressive pattern of production and trade specialization.

A charcoal sample from a coastal shell mound of Rio de Janeiro State was dated by {sup 14} C-AMS to 7, 860+- 80 years B P as part of an interdisciplinary project between physicists and archaeologists. This is an unexpected result that reinforces two similar previous early dates for the same region, which were questioned by Brazilian archaeologists because they implied in pulling back by some two thousand years the antiquity consensually accepted for the settlement of that region.

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

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

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

    Leishmaniasis is a major public health problem, and the alarming spread of parasite resistance has increased the importance of discovering new therapeutic products. The present study aimed to investigate the in vitro leishmanicidal activity from 16 different Brazilian medicinal plants. Stationary-phase promastigotes of Leishmania amazonensis and murine macrophages were exposed to 44 plant extracts or fractions for 48 h at 37°C, in order to evaluate their antileishmanial activity and cytotoxicity, respectively. The most potent extracts against L. amazonensis were the hexanic extract of Dipteryx alata (IC50 of 0.08 μg/mL), the hexanic extract of Syzygium cumini (IC50 of 31.64 μg/mL), the ethanolic and hexanic extracts of leaves of Hymenaea courbaril (IC50 of 44.10 μg/mL and 35.84 μg/mL, respectively), the ethanolic extract of H. stignocarpa (IC50 of 4.69 μg/mL), the ethanolic extract of Jacaranda caroba (IC50 of 13.22 μg/mL), and the ethanolic extract of J. cuspidifolia leaves (IC50 of 10.96 μg/mL). Extracts of D. alata and J. cuspidifolia presented higher selectivity index, with high leishmanicidal activity and low cytotoxicity in the mammalian cells. The capacity in treated infected macrophages using the extracts and/or fractions of D. alata and J. cuspidifolia was also analyzed, and reductions of 95.80%, 98.31%, and 97.16%, respectively, in the parasite burden, were observed. No nitric oxide (NO) production could be observed in the treated macrophages, after stimulation with the extracts and/or fractions of D. alata and J. cuspidifolia, suggesting that the biological activity could be due to mechanisms other than macrophage activation mediated by NO production. Based on phytochemistry studies, the classes of compounds that could contribute to the observed activities are also discussed. In conclusion, the data presented in this study indicated that traditional medicinal plant extracts present effective antileishmanial activity. Future studies could focus on

    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.

    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

    Varre-Sai, the most recent Brazilian meteorite fall, on June 19th, 2010 at Varre-Sai, in Rio de Janeiro State, Brazil (20°51'41″S; 41°44'.80″W). At least eight masses (total ~3.5 kg) were recovered. Most are totally covered by fusion crust. The exposed interior is of light-grey colour with a few dark shock veins. Five thin polished and etched sections were prepared from a slice weighing 35 g on deposit at the National Museum/UFRJ. It consists mostly of chondrules ranging in size from 0.35 to ~2.2 mm, and chondrule fragments enclosed in a crystalline matrix. The matrix consists of tiny isolated subhedral and anhedral crystals and opaque minerals that are intergrown with broken chondrules. The chondritic texture is poorly defined with chondrule textures that vary from non-porphyritic to porphyritic ones. The essential minerals are olivine (Fa25±0.2) and low-Ca pyroxene (Fa21.66±0.2Wo1.4). Accessory minerals are plagioclase, apatite, Fe-Ni metal phases, troilite, chromite and magnetite. Mössbauer spectroscopy analysis confirms that the mineral phases are olivine, pyroxene, troilite and kamacite/taenite. Chemical data indicate that Varre-Sai is a member of the low iron L chondrite group. The observed texture and mineral phases led us to classify Varre-Sai as an equilibrated petrologic type 5. The shock features of the minerals (undulatory extinction, planar structure and numerous cracks), as well as plagioclase partial or totally transformed to maskelynite, suggest a shock stage S4. Also, some post-impact metamorphic processes could be inferred from the meta-sulfide conjoint grains that show complex mixtures of kamacite-taenite-tetrataenite and troilite. The occurrence of veins crosscutting the studied sections indicates that Varre-Sai was affected by a late fracturing event. Sealing of these fractures must have been a fast process, as shown by troilite globule textures pointing towards rapid solidification. The meteorite name was approved by the Nomenclature

Ecological study, in which 2,612 police reports registered in Police Stations were analyzed. An instrument was used to obtain data from the victim, the aggressor and the type of violence. Psychological abuse predominated and most cases occurred in the older adults own home. In the cities of Ribeirão Preto and João Pessoa, the older adults presented similar rates for both gender. Regarding the standardized rates, in João Pessoa, there was a rise of this type of abuse in the two first years, and later there was a certain stability. In the city of Teresina, there was an increase, also observed in the city of Ribeirão Preto in the three first years, followed by a decrease. Older adults abuse is a cultural phenomenon difficult to be reported by them, since it occurs in the family context.

    Full Text Available The article represents a theoretical and methodological approach to the analysis of organizational dynamics of political parties today, based on a study of the Party of Brazilian Social Democracy (PSDB in the State of Sao Pãulo (period between 1988 to 2006. It is hypothesized that the structure and the institutional rules of a particular party, or even their election results, are insufficient to explain the inner workings, such as the role of party organization in the electoral system. An approach that articulates the relationship patterns, election results and posts held in the party, identified the factors that explain the political capital that circulated within the party and ensured its organizational dynamics over the period analyzed.

    The objective of this study was to analyze the diversity and discrimination of high-performance Brazilian rice cultivars using microsatellite markers. Twenty-nine rice cultivars belonging to EMBRAPA Arroz e Feijão germplasm bank in Brazil were genotyped by 24 SSR markers to establish their structure and genetic discrimination. It was demonstrated that the analyzed germplasm of rice presents an expressive and significant genetic diversity with low heterogeneity among the cultivars. All 29 cultivars were differentiated genetically, and were organized into two groups related to their upland and irrigated cultivation systems. These groups showed a high genetic differentiation, with greater diversity within the group that includes the cultivars for irrigated system. The genotyping data of these cultivars, with the morphological e phenotypical data, are valuable information to be used by rice breeding programs to develop new improved cultivars.

    During the last decades there have been many changes in the banking sector organization. It has been also observed the mutual growing of musculoskeletal and mental disorders. This study investigated the workload of bank tellers at a Brazilian public institution. It was performed the Ergonomic Work Analysis (EWA). Three employees participated in this study. During the analysis process, three research instruments were applied: Inventory of Work and Risk of Illness, Yoshitake Fatigue Questionnaire and Nordic Musculoskeletal Questionnaire, beyond the realization of footage recordings and the self-confrontation. The results indicated the existence of an excess of workload on the evaluated workstations, mainly in relation to mental order constraints, that overlaps the physical aspects. Thereby it was found that the employees tend to adopt strategies trying to reduce the impacts of the excess of workload, in order to regulate it.

    Full Text Available The growth of industries and the strong economic base in Brazil require improvements and adaptations in business processes. Cross-functional teams (CFT may help to companies achieve these improvements. This research looks at characterizing CFT according to application processes, structures, objectives and impacts, considering the context of demand planning and related processes. In-depth interviews with 22 managers were performed in three Brazilian manufacturing companies. A framework to characterize CFT and respective impacts is proposed, including elements such as: procedures, context and goals, power distribution, impacts on cross-functional integration, impacts on teams' performance and on organization's performance. One significant managerial finding is that effective and efficient CFTs need balanced distribution of power among members by effectively establishing and structuring the team. By doing this, managers may observe positive impacts on inter-functional integration and in firm's results. Moreover, teams should permanently perform joint planning to predict unfavorable situations, improve communication and mutual understanding.
