title: Diagnostic comparison of Corynebacterium pseudotuberculosis through microbiological culture and PCR in sheep samples

description: Caseous lymphadenitis is a chronic infectious disease caused by Corynebacterium pseudotuberculosis , which is a bacterium responsible for a great number of economic losses on goat and sheep production. It is characterized by the formation of abscesses in superficial lymph nodes and in internal organs and lymph nodes. This study aimed at determining the agreement between microbiological culture and PCR in the identification of C. pseudotuberculosis , in samples collected from animals in slaughterhouses and in animals that presented lymph node enlargement in field conditions. From the 202 samples analyzed through microbiological culture, 113 (56%) were positive for Corynebacterium sp.; from these positive samples, 38 (34%) were identified as C. pseudotuberculosis by microbiological culture. From the amount of samples, 110 (54%) were positive and 92 (46%) were negative in the PCR. Kappa index (0.193) presented a weak agreement between PCR and microbiological culture. We concluded that molecular diagnosis (PCR) in clinical samples proved to be more efficient, reproducible, and faster than the microbiological culture, both on clinical samples analyses and in the confirmation of C. pseudotuberculosis in colonies that were classified by Corynebacterium genus. Thus, the present study demonstrated the importance of PCR to confirm C. pseudotuberculosis diagnosis, and the best contribution for the epidemiological surveillance of the disease in sheep.

title: Sanitary conditions of the Amazonian guarana drink sold by street vendors in the city of São Luís, MA

description: ABSTRACT: The objective of this study was to evaluate the hygienic-sanitary conditions of the Amazonian guarana drink sold by street vendors in the city of Sao Luís, Maranhão, Brazil. Thirty samples from 10 outlets were subjected to the following microbiological analysis: Salmonella spp., quantification of the most probable number of coliforms at 35°C and 45°C, enumeration of mesophilic aerobic bacteria, fungi and Staphylococcus coagulase-positive. A check-list questionnaire was administered at each point of sale assessed to check the hygienic conditions of the site and preparation of the drink. Except for Salmonella spp., all microorganisms studied were found in the samples. We found high counts of coliforms at 35ºC (n=24; 80%) and 45°C (n=18; 60%), indicating inadequate sanitary conditions of the samples. Also, there were numerous gaps in retail outlets, indicating impairment in the preparation of the Amazonian guarana drink. The results reinforce the importance of investing in quality programs, awareness and training for street vendors in the city of Sao Luís, Maranhão.

title: Sustainability, Value, Performance and Risk in the Brazilian Capital Markets

description: ABSTRACT The study of the relationship between best practices in sustainability and better business management is one of the most relevant and current issues involving researchers and professionals who deal with this subject. For this survey, a representative sample of 205 Brazilian publicly traded companies - between the 2005 and 2009 period - was selected. A possible relationship between ranking in the Bovespa sustainability index, used as a proxy for sustainability best practices, and those companies’ indexes of management quality was investigated. After applying a variety of econometrics models, it was possible to confirm that best sustainability practices are associated with higher performance, higher value and lower risk. Moreover, sustainability is associated with value, both directly and through mediated variables of performance and risk. Finally, market value, operating leverage, return on assets (ROA) and volatility are possible determinants of sustainability practices’ quality.

title: Producción de conidios y clamidosporas de los hongos Duddingtonia flagrans y Monacrosporium thaumasium en diferentes medios sólidos

description: RESUMEN Las especies Duddingtonia flagrans y Monacrosporium thaumasium son micro-hongos considerados promisorios agentes del control biológico de parásitos. Bajo condiciones adversas como la falta de nutrientes, estos hongos producen esporas capaces de sobrevivieren después de pasar por el tracto gastrointestinal de los animales. La formación de estas estructuras es una característica deseable ya que promueve la sobrevivencia y la diseminación de los hongos para propósitos de biocontrol. El objetivo de este estudio fue evaluar la producción de esporas de dos especies de hongos nematófagos D. flagrans (aislados AC001 y CG722) y M. thaumasium (NF34A). Estos fueron cultivados en los subproductos agroindustriales, que tenían el intento de identificar el mejor medio para uso en programas de biocontrol de nematodos. Diferentes volúmenes (10, 15 y 20 mL) de masa micelial fueron utilizados como inóculos iniciales y adicionados a 100 gramos de medios de crecimientos sólidos (sémola de arroz - QA; sémola de maíz - QM; bagazo de caña - BC; paja de arroz - PA y cascara de café - CC) y mantenidos a 25°C en la obscuridad para evaluar la producción de esporas. Los aislados AC001 y CG722 mostraron las mejores producciones en el medio de la QA (p&lt;0,05). El volumen de 20 mL de masa micelial utilizado como inóculo inicial proporcionó una mayor recuperación de esporas. El aislado NF34A presentó una baja o nula producción de estructuras reproductivas en los diferentes volúmenes y medios de crecimientos utilizados. La mejor producción de esporas se obtuvo utilizando subproductos de la agroindustria con mayor densidad proteica y energética.

title: Epidemiologic of orthopedic trauma study in a public emergency

description: Abstract Introduction The trauma has emerged as a serious public health problem, because it compromises the individual’s functionality as its social and economic participation in society. Method Retrospective study using information of 1390 records. Data collection occurred from September 2011 to February 2012 and the variables studied were: age, gender, mechanism of injury, the affected body part, treatment performed, conduction mode, day of the week that the service was performed, length of hospital stay and hospital output condition. Results The results showed a predominance of men in the age group 18-38 years. The orthopedic trauma was found more often in the lower limbs (23.2%) due to traffic accidents (60.1%). Surgical treatment was the most common (89.8%) and the majority of the patients progressed to discharge from the hospital (79.4%). Sunday was the day of the week that most trauma victims were admitted (18.9%) and ambulances from inside the municipalities were the main way to the hospital (34.1%). Most patients remained hospitalized for a period of 1 to 15 days (89.4%). Conclusion The results confirmed the need for preventive measures of orthopedic trauma associated with the awareness of the population on the morbidity caused by orthopedic trauma.

title: Spatial analysis of the quality of Primary Health Care in Brazil

description: ABSTRACT This article aims to analyze the spatial distribution of the Primary Health Care (ABS) teams evaluated by the National Program for Access and Quality Improvement in Primary Health Care (PMAQ-AB) according to the categories of performance for certification in the Program. A spatial distribution profile of the municipalities according to the PMAQ-AB evaluation was carried out, as well as the identification of spatial patterns from a spatial correlation indicator to evaluate the degree of space influence for the certification of ABS teams. It was found presence of spatial patterns in relation to ABS quality. Municipalities with low values in the indicator, whose neighbors are also low, are found in most of the states of Acre, Amazonas, Roraima and Amapá, as well as in Rio de Janeiro and Espírito Santo. High-high standard clusters were observed in the municipalities of São Paulo, Minas Gerais and Rio Grande do Sul, especially in Santa Catarina. The identification of the spatial quality standards of ABS can be a valuable resource for the further PMAQ-AB development. It will be possible, thus, to develop analyses that incorporate variables with explanatory potential for the spatial patterns of ABS quality found in Brazilian municipalities.

title: Higher Education Systems and the Tuition Fees Charging: Perspectives and Perceptions in Brazil, Canada and China

description: ABSTRACT This study aims to understand the perceptions of the tuition fees charging in Canada and China and the perspectives of this practice in Brazil, which is a country where society requires access to quality higher education, but which faces large budgetary constraints on its public funding. To understand these questions, a qualitative exploratory multi-case study was carried out with government officials, specialists in higher education, and student leadership from all three countries. In conclusion to this analysis, and considering the benefits provided by the Canadian and Chinese participants, it is suggested for Brazil to perform a reflection on this subject. The study shows that such an initiative can boost public higher education institutions through greater financial availability and democratize access and permanence, as there would be more resources to invest and assist students from underrepresented groups participating in the system.

title: Divergences Between New Patterns of Global Trade and Brazil/Mercosur

description: Although integration has been a part of South American discourse for decades, the level at which it is actually promoted remains far from that which is observed in dynamic production and trading centers. Given transformations in global trade, the phenomenon of global value chains is, in fact, very regionalized. We ask whether the trading pattern of Mercosur countries is aligned with approaches based on regional value chain, and if not, how it differs and why. In our evidence and analysis, we primarily use traditional gross trade data and Trade in Value Added (TiVA) indicators, and we look more at countries' profiles. We show that there has been a decrease in Brazilian trade with Mercosur, with manufactured exports being the main reason for the decline. We indicate that, in addition to the effect of China in the 2000s, there has been a structural movement of Mercosur economies, mainly regarding Brazil, which supports a hypothesis of primarization or deindustrialization. Our results show that Brazil and Argentina are both relatively closed to foreign trade, as well as global and regional value chains, which makes them even more poorly integrated with one another. This reinforces what we call Mercosur's 'introspective' model of integration, making it less outward-oriented, which is divergent with what is observed when regional value chains are encouraged.

title: Politics on the Web: Using Twitter to Estimate the Ideological Positions of Brazilian Representatives

description: The use of social media has become increasingly widespread among citizens and politicians in Brazil. This means of communication served as a key arena for debate and propaganda during the 2014 legislative and presidential elections, when a very polarized political scenario emerged. New approaches have been developed that use information from the social network structure constructed by political actors on social media platforms, such as Twitter, in order to calculate ideal points. Can data from the decision to 'follow' a profile on Twitter be used to estimate politicians' ideological positions? Can approaches like this show the variance of political positions even within a very fragmented legislative body, such as the Brazilian Chamber of Deputies? This article presents and analyzes the successful application of a Bayesian spatial model developed by Barberá (2015), using data from Brazil. This method allowed to capture differences between parties and political actors similar to those found by means of roll call votes. It also makes possible to calculate ideal points for actors who participate in the public debate, but are not professional politicians.

title: Dynamics of the real estate market in historic centers in times of globalization: the cases of Recife, Belém and São Luís (Brazil)

description: Abstract The slow growth of Brazilian economy since the 1990s and its insertion into the global economy have brought consequences for historic centers. Political-administrative decentralization and competition among cities for private investment have prompted local governments to invest in these centers to attract activities, which has affected their real estate market dynamics. This article compares how these market dynamics have occurred in the Historic Centers of Recife, Belém and São Luís (Northeastern Brazil) and the effects on their spatial organization, showing their regularities and specificities. As a result of these dynamics, pre-existing spaces (degraded areas) are sometimes reproduced or, otherwise, recreated by way of requalification. This reveals the different ways in which these centers are inserted in the global economy.
