Head and neck lymphedema: what is the physical therapy approach? A literature review
Authors: Della Justina Lunara Basqueroto , Dias Mirella
Published: July 2016

Abstract Introduction: Head and neck lymphedema is considered a chronic and complex complication with potential to cause physical, functional, emotional and social impairment. Objective: To identify the approaches to physical therapy used to treat head and neck cancer-related lymphedema. Method: A bibliographic search was conducted in February and March 2012 in books and electronic databases, LILACS, MEDLINE, SCIELO, Cochrane, PEDro, and BDTD using the following keywords: lymphedema, treatment, head and neck cancer, and physical therapy connected by the Boolean operator AND without a specific time frame. Results and discussion: Early diagnosis and assessment is key to properly managing and effectively treating lymphedema. Diagnosis is reached through clinical history and physical assessment by measuring the distance between two anatomical landmarks, circumference measures, and lymphedema rating scales. Complex decongestive therapy, which includes manual lymph drainage, compressive bandaging, kinesiotherapy and skin care, is the technique most frequently used and currently considered to be the gold standard. Conclusions: No consensus is reported in the literature in regard to a standard procedure to assess and treat head and neck cancer-related lymphedema. Assessments and treatments described in the literature are mainly restricted to the limbs; therefore, further studies are needed to support effective clinical actions in the physical therapy approach to this condition.

ABSTRACT: The objective of this study was to compare the functions of Wilmink and Ali and Schaeffer with Legendre polynomials in random regression models using heterogeneous residual variances for modeling genetic parameters during the first lactation in the Holstein Friesian breed. Five thousand eight hundred and eighty biweekly records of test-day milk production were used. The models included the fixed effects of group of contemporaries and cow age at calving as covariable. Statistical criteria indicated that the WF.33_HE2, LEG.33_HE2, and LEG.55_HE4 functions best described the changes in the variances that occur throughout lactation. Heritability estimates using WF.33_HE2 and LEG.33_HE2 models were similar, ranging from 0.31 to 0.50. The LEG.55_HE4 model diverged from these models, with higher estimates at the beginning of lactation and lower estimates after the 16th fortnight. The LEG55_HE4, among the three better models indicated by the index, is the one with highest number of parameters (14 vs 34) and resulted in lower estimation of residual variance at the beginning and at the end of lactation, but overestimated heritability in the first fortnight and presented a greater difficulty to model genetic and permanent environment correlations among controls. Random regression models that used the Wilmink and Legendre polynomials functions with two residual variance classes appropriately described the genetic variation during lactation of Holstein Friesians reared in Rio Grande do Sul.

Published: July 2016

ABSTRACT: The aim of this study was to determine phyllochron in strawberry cultivars, from two origins during two crop years, conducted in low tunnel. Experiments were conducted at the Universidade Federal de Santa Maria, campus Frederico Westphalen (CESNORS/UFSM), Brazil, evaluating 'Camarosa', 'Camino Real' and 'Albion' strawberry cultivars. During the 2012 crop year, seedlings from Chile and Pelotas/RS, Brazil were evaluated, for the 2013 crop year, only seedlings from Chile were submitted to evaluations. In order to determine the phyllochron, twice a week the numbers of leaves (NL) of the main crown were counted and a regression between NL and accumulated thermal time (ATT) was held. The experimental design was a complete randomized block, with three repetitions with the evaluation of 12 plants per experimental unity, consisting of a factorial. For 2012 and 2013 crop years, it is possible to conclude that 'Camarosa' and 'Camino Real' cultivars required higher accumulation of degree-days (ºC day-1) to issue each successive leaf than cv. 'Albion', which, in turn, presented higher rates of leaf emergence, being considered earlier. Regarding to origin, seedlings from cv. 'Albion' from Chile presented lower total phyllochron values and for samples from Pelotas, no difference among cultivars was observed.

Published: July 2016

ABSTRACT: Erwinia psidii causes bacterial blight of guava ( Psidium guajava ), an important disease of this crop in Brazil. The pathogen affects branches and twigs of guava trees, reducing yield significantly. Bacterial dissemination often occurs through contaminated but asymptomatic propagating plant material. The objectives of this research were to evaluate the use of BIO-PCR and conventional PCR to detect E. psidii in inoculated guava plants grown in a greenhouse and in symptomatic and asymptomatic trees from guava orchards. Erwinia psidii strain IBSBF 1576 was inoculated (107CFU mL-1) into young guava shoots and plant tissue was analysed at 0, 5, 10, and 15 days after inoculation. Symptoms were observed after 5 days and all inoculated shoots were PCR positive at all times, by both BIO-PCR and conventional PCR. Under natural infection conditions, 40 samples were tested by BIO-PCR from each of three guava orchards, 20 showing symptoms and 20 asymptomatic. PCR was positive for 58 out of 60 symptomatic samples (96.7%) and for 6.7% of asymptomatic samples, showing that the method can be used to detect the pathogen at early stages of infection. This PCR method may be used as a diagnostic tool to assess bacterial survival, dissemination and disease outbreaks.

Published: July 2016

ABSTRACT: The purpose of this research was to investigate the progress of the rancidity in Nile tilapia diets containing bacterial biomass of Rubrivivax gelatinosus . Six experimental treatments comprised basal diet (negative control), diet with asthaxanthin (positive control) and 4 diets with different concentrations of the bacterial biomass. The thiobarbituric acid assay for rancidity analyses were accomplished after 6 and 12 months of diets storage. It was concluded that Rubrivivax gelatinosus biomass minimized the racidity in Nile tilapia diets in 32.52 to 44.72% at 6 months and in 37.85 to 52.37% at 12 months of storage.

Primitivo e loucura, ou o inconsciente e a psicopatologia segundo Arthur Ramos
Authors: Pereira Mário Eduardo Costa , Gutman Guilherme
Published: July 2016

O psiquiatra brasileiro Arthur Ramos dá continuidade à tradição de uma abordagem antropológica e cultural dos fenômenos psicopatológicos iniciada por Raimundo Nina Rodrigues. Na primeira metade do século XX, Ramos estuda o fenômeno da loucura através de uma interlocução com a psicanálise e com a antropologia. Sua contribuição situa-se além do referencial estritamente psicopatológico, permitindo, também, uma interrogação fecunda sobre os processos de subjetivação próprios aos contextos culturais brasileiros, sobretudo o dos pobres e o dos negros.
O novo comparatismo e o contexto latino-americano
Authors: Coutinho Eduardo F.
Published: July 2016

Resumo Levando-se em conta o que hoje se entende por “novo comparatismo” – isto é, uma Literatura Comparada que não se atém apenas aos estudos de caráter binário entre obras, autores e movimentos literários, nem ao cânone da tradição ocidental, mas que se encontra aberto a todo tipo de expressão literária e cultural e a outras áreas do conhecimento, visando a um verdadeiro diálogo entre culturas –, buscaremos neste trabalho investigar algumas das tentativas que têm surgido no contexto latino-americano de estabelecimento desse diálogo e a possibilidade de constituição do que vem sendo designado de “geocultura latino-americana”.
Poéticas del tránsito: el arte latinoamericano contemporáneo desde un análisis transmedial
Authors: Rolle Carolina
Published: July 2016

Resumen En este artículo se presentan los argumentos iniciales de una investigación que intenta dar cuenta de diferentes poéticas latinoamericanas contemporáneas producidas en la expansión de los límites de la lengua, del espacio, de los géneros y de los medios. Para ello se propone un corpus que se inscribe en esta problemática a partir de procesos de hibridización cultural que surgen en las grandes ciudades. Se trata de construir diálogos intermediales y transgenéricos a partir de la configuración de la categoría de transmedialidad que, a su vez, permite analizar los imaginarios urbanos que configuran estas poéticas en la tensión entre lo local y lo global.
Um mundo de papel – reflexões sobre o realismo de Luiz Ruffato
Authors: Schøllhammer Karl Erik
Published: July 2016

Resumo A partir do romance Flores artificiais, de Luiz Ruffato, o ensaio discute uma radicalização nas demandas do real na literatura brasileira contemporânea, em busca de outro fundamento para um realismo contemporâneo sustentado por falas e escritos de personagens que já não são representados literariamente, mas apropriados e incluídos em sua própria materialidade. Tais dispositivos precisam ser entendidos à luz do que Jacques Rancière chamou de “regime ético da imagem”, na medida em que procuram expressões que são ontologicamente determinadas pelo real solicitado.
O resgate de uma experiência esvaziada: El ruido de las cosas al caer e a ficção sobre o narcotráfico

Published: July 2016

Abstract Objective: to analyze undergraduate nursing students' perception of biological risk and its relationship with their prior practical training. Method: a descriptive cross-sectional study was conducted among undergraduate nursing students enrolled in clinical practice courses in the academic year 2013-2014 at the School of Nursing at the University of Barcelona. Variables: sociodemographic variables, employment, training, clinical experience and other variables related to the assessment of perceived biological risk were collected. Both a newly developed tool and the Dimensional Assessment of Risk Perception at the worker level scale (Escala de Evaluación Dimensional del Riesgo Percibido por el Trabajador, EDRP-T) were used. Statistical analysis: descriptive and univariate analysis were used to identify differences between the perception of biological risk of the EDRP-T scale items and sociodemographic variables. Results: students without prior practical training had weaker perceptions of biological risk compared to students with prior practical training (p=0.05 and p=0.04, respectively). Weaker perceptions of biological risk were found among students with prior work experience. Conclusion: practical training and work experience influence the perception of biological risk among nursing students.

Abastract Objective: to discern the profile of the Spanish Emergency Contraceptive users (EC). Design: systematic review of contraceptive use in the Spanish population. Data Source: Spanish and international databases, between January 2006 - March 2011. Keywords: Contraceptives, Postcoital pills, emergency contraception, levonorgestrel, data collection. Study selection: original papers, letters to the editor in which stated aims were the description, prediction or measurement of variables related to EC use. Twenty-two papers were retrieved and fourteen were finally selected, all of which were descriptive. Data extraction: manuscripts were evaluated by two independent reviewers. Results: Women requesting EC have ages between 21-24 years, mostly single and university students; declare that they have not previously used EC, and attend an Emergency department, at weekends and within 48 hours following unprotected sexual intercourse. The reason is condom rupture. None of the studies reviewed measured alcohol and other drug consumption, the number of sexual partners, nor any of the studies performed a comparison with a group not using EC. Conclusions: lack of homogeneity and comprehensiveness of studied variables resulted in a limited profile of Spanish EC users. Further studies are needed with a more comprehensive approach if sexual health interventions are to be carried out in possible users.
The experience of nurses in care for culturally diverse families: A qualitative meta-synthesis
Authors: Murcia Saidy Eliana Arias , Lopez Lucero
Published: July 2016

Abstract Objective: to understand the experience of nurses in care delivery to culturally diverse families. Method: qualitative meta-synthesis. Exhaustive search in seven databases, three repositories and a manual search in references without time limit, in English, Spanish and Portuguese, resulting in 1609 potentially relevant studies. These were assessed based on the title, summary and full text, determining the final inclusion of 14 studies. Two independent reviewers used the Critical Appraisal Skills Programme (CASP) to assess the quality. The interpretative synthesis implied permanent contrast and consensus among the authors, revealing four categories and one meta-theme. Results: "taking care of a culturally diverse family, the experience of crossing a tightrope". Conclusion: the experience of nurses in care delivery to culturally diverse families is demanding and challenging because it imprints a constant tension among barriers, cultural manifestations and the ethical responsibility of care, incipiently revealing elements of cultural competency. The omission of information in the participants' reports in the studies represents a limitation. The findings offer a baseline for professionals and organizations to focus their intervention efforts on the continuing barriers in care delivery to culturally diverse families and strengthens the need for cultural competency training for nurses.

Abstract Some macrophytes species show a high growth potential, colonizing large areas on aquatic environments. Cattail (Typha angustifolia L.) uncontrolled growth causes several problems to human activities and local biodiversity, but this also may lead to competition and further problems for this species itself. Thus, the objective of this study was to investigate anatomical modifications on T. angustifolia plants from different population densities, once it can help to understand its biology. Roots and leaves were collected from natural populations growing under high and low densities. These plant materials were fixed and submitted to usual plant microtechnique procedures. Slides were observed and photographed under light microscopy and images were analyzed in the UTHSCSA-Imagetool software. The experimental design was completely randomized with two treatments and ten replicates, data were submitted to one-way ANOVA and Scott-Knott test at p<0.05. Leaves from low density populations showed higher stomatal density and index. These modifications on stomatal characteristics were more evident on the leaf abaxial surface. Plants from low density populations showed thicker mesophyll and higher proportion of aerenchymal area. Roots from low density populations showed a higher proportion of the vascular cylinder. Whereas, plants from higher density populations showed greater thickness of the endodermis, exodermis, phloem and root cortex. Higher density populations showed a higher proportion of aerenchymal gaps in the root cortex. Therefore, cattail plants from populations growing under high density population show anatomical traits typical of plants under stress, which promotes the development of less functional anatomical modifications to aquatic environments.

Abstract Crepuscular period is one of the factors that may influence the biting activity of mosquitoes. Many of these insects have a peak activity in this period. The purpose of this study was to investigate the afternoon crepuscular activity of Culicidae in a remaining area of Atlantic Forest in western Santa Catarina, southern Brazil. Moreover, the possible influence of abiotic factors, the abundance and species richness were verified. In order to better analyze the influence of crepuscular period in specific composition and abundance of mosquitoes, the dusk was divided into three periods: pre-sunset, sunset and post-sunset. At the end of the study, nine hundred and eight four specimens distributed in 12 genera and 23 species were collected. Trichoprosopon pallidiventer (Lutz, 1905) (59.76%), Aedes crinifer (Theobald, 1903) (8.13%), Ae. scapularis (Rondani, 1848) (5.89%) were the most abundant species. Spring time presented the greatest abundance and species richness. During the study, among the three periods evaluated, pre-sunset had the greatest abundance and post-sunset the lowest. Pre-sunset and sunset had the greatest similarity between species. Regarding to the abiotic factors evaluated seven and 15 days before sampling, they did not present significant correlation for the three most abundant species. However, temperature had a positive correlation to these species. Moreover, the correlation between collected species and its possible role as vectors of etiological agents of diseases was discussed.
Beetle diversity in fragmented thornscrub and isolated trees

Published: July 2016

Abstract Due to land use change mainly for induced agriculture, Tamaulipan thornscrubin northeast Mexico has been cleared and transformed into small patches of vegetation as small as isolated trees surrounded by agricultural fields. In this study, we explored how tree isolation or growing inside a fragment of remnant vegetation influence diversity of coleopterans in two plant species (Prosopis laevigata (Humb. &Bonpl.exWilld.) M.C. Johnst. (mesquite) and Ebenopsis ebano (Berl.) Barneby (Texas ebony). We found 72 coleopteran morphospecies; fifteen occurred mainly in remnant fragments and ten mainly in isolated trees. There were more insects under isolated mesquites than under those immersed in remnant fragments, while in Texas ebony the highest beetle density for isolated trees coincided with periods of bean and maize in surrounding agriculture.

Abstract In this article, by using carbon stable isotopes, we assessed the past and present land use influences that riparian areas are subject within agricultural landscapes. Emphasis is given to the understanding of the effects of the 2012 Brazilian Forest Act on such areas. We selected five riparian areas within a highly C4 dominated agricultural landscape. Three of them had 30 meters native riparian forest buffer (NRFB) and two of them had 8 meter and no NRFB. We used three 100 meter-transects located 5, 15 and 30 meters relative to stream channel to obtain soil samples (0 - 10 cm). All riparian areas presented soil carbon isotopic signatures that are not C3 (native forests) irrespective of having or not 30 meters NRFB. Two cases presenting less than 30 meters NRFB had higher C4 derived carbon contribution. All of the other three areas that followed the 30 meters NRFB presented, to some degree, C4 derived carbon, which was attributed to C4 organic matter deposition originated from cultivated areas and, in one case, to the persistence of former exotic grasses. With the 2012 Forest Act allowing narrower buffers (< 30 meters), we expect C4 contributions to soil organic matter to remain high in riparian areas and streams within agricultural landscapes dominated by C4 plants where 30 meter NRFB is no longer required. Such contributions will likely continue to have detrimental effects on stream water quality and biota.

Resumo: Este artigo tem como objetivo discutir as maneiras como as mulheres são representadas nas fotonovelas publicadas na revista Capricho entre os anos de 1950 e 1960. As décadas citadas foram o auge das fotonovelas no Brasil. Sua leitura, assim como a de outras revistas femininas, ajudava a integrar as mulheres na sociedade urbana, divulgando modos e modas a serem seguidos e copiados. Para tanto, foram analisadas vinte fotonovelas publicadas na revista citada destacando a construção da imagem de heroínas/mocinhas que serviram de "modelo" e inspiração para muitas mulheres leitoras da Capricho. Dessa forma, busco abordar a participação das fotonovelas na construção de subjetividades e de determinados modos de ser homem e de ser mulher.
Usos de substâncias psicoativas por mulheres: a importância de uma perspectiva de gênero
Authors: Alves Tahiana Meneses , Rosa Lúcia Cristina dos Santos
Published: July 2016

Resumo: O objetivo do artigo é promover, através de pesquisa teórica bibliográfica, uma reflexão sobre os usos de substâncias psicoativas por mulheres. Reconhecer a necessidade de uma abordagem interdisciplinar, mas investir nos aspectos socioculturais relativos a tais práticas é o foco. O gênero, enquanto um determinante sociocultural, é priorizado. Homens e mulheres - enquanto diferentes atores sociais/culturais - conservam envolvimentos distintos com o consumo de substâncias psicoativas. Assim, considera que as mulheres constituem um segmento diferenciado de usuárias, com características e necessidades particulares, que devem ser consideradas pelas políticas públicas. As próprias mulheres, porém, não constituem um grupo homogêneo. Portanto, uma abordagem aos seus consumos de substâncias psicoativas deve ser feita integralmente, levando em conta os seus contextos e particularidades, e pautada em uma perspectiva de Redução de Danos.
Return and Liquidity Relationships on Market and Accounting Levels in Brazil
Authors: Perobelli Fernanda Finotti Cordeiro , Famá Rubens , Sacramento Luiz Claudio
Published: July 2016

ABSTRACT This article discusses profitability-liquidity relationships on accounting and market levels for 872 shares of publicly-traded Brazilian companies, observed between 1994 and 2013. On the market level, the assumption is that share liquidity is able to reduce some of the risks incurred by investors, making them more willing to pay a higher price for liquid shares, which would lower expected market returns. On the accounting level, the basic hypothesis argues that a firm's holding more liquid assets is related to a conservative investment policy, possibly reducing accounting returns for shareholders. Under the assumption of financial constraint, however, more accounting liquidity would allow positive net present value investments to be carried out, increasing future accounting returns, which would positively affect market liquidity and share prices in an efficient market, resulting in a lower market risk/expected return premium. Under the assumption of no financial constraint, however, more accounting liquidity would only represent a carry cost, compromising future accounting returns, which would adversely affect market liquidity and share prices and result in a higher market risk/expected return premium. Among the hypotheses, the presence of a negative market liquidity premium was verified in Brazil, with shares that traded more exhibiting a higher expected market return. On the margins of the major theories on the subject, only two negative relationships between excess accounting liquidity and market liquidity and accounting return, supporting the carry cost assumption for financially unconstrained firms, were verified. In terms of this paper's contributions, there is the analysis, unprecedented in Brazil as far as is known, of the relationship between liquidity and return on market and accounting levels, considering the financial constraint hypothesis to which the firms are subject.
Motivational Factors for the Master's Degree: a Comparison between Students in Accounting And Economics in the Light of the Self-Determination Theory,

Published: July 2016

ABSTRACT The general aim of this study was identifying the motivational level of students in Accounting and Economics regarding the search for a stricto sensu graduate degree. Also, it sought to determine the variables that significantly influence the motivation of these individuals. Having the Self-Determination Theory as a basis, a questionnaire was prepared resorting to the Academic Motivation Scale developed by Vallerand, Pelletier, Blais, Brière, Senécal, and Vallières (1992), and translated into Portuguese by Sobral (2003). The database contains observations of 173 university students from public institutions in Minas Gerais, Brazil, which provided courses in Accounting and Economics. The methodological procedure consisted in conducting a non-parametric test of mean values for the Motivation Self-Determination Index (MSI) of students, in calculating the correlations between the MSI and individual characteristics of students, and finally in estimating multiple linear regressions. Research results indicated that students in Accounting showed no difference regarding the motivational level when compared to students in Economics. It was also possible to notice that women, older students, scientific initiation scholarship holders, those from lower socioeconomic backgrounds, and those whose mothers have higher educational level tend to have a rather self-determined motivation. Additionally, it was found that insertion into the labor market increases self-determined motivation to pursue a stricto sensu Master's degree only in the case of students in Accounting. The research was limited to the fact that the sample only included students of public education institutions from Minas Gerais. For future research, it is suggested that the procedures of this study be replicated in privet institution and in different states.
Consequences for Future Return with Earnings Management through Real Operating Activities
Authors: Cupertino César Medeiros , Martinez Antonio Lopo , Costa Jr Newton Carneiro Affonso da
Published: July 2016

ABSTRACT This article analyzes earnings management through real operating activities by firms in the Brazilian capital market. This way of manipulating outcomes takes place when managers make suboptimal decisions in terms of timing and volume of operating activities. This study tests the hypothesis that firms engaged in earnings management through real operating activities might have a negative impact on future returns. Our analysis is restricted to nonfinancial firms listed on the Brazilian Securities, Commodities, and Futures Exchange (BM&FBOVESPA) with annual data made available by the Economatica(r) for the years from 1989 to 2012. Empirical tests involving regression on panel data and estimation of future firm returns and outcomes indicate a negative impact on return on assets (ROA) related to manipulation through real operating activities. This finding is useful for several stakeholders. It demonstrates that manipulation through real operating activities takes place in the Brazilian capital market, suggesting that earnings management extends beyond discretionary accounting choices in this country. The main contribution is demonstrating a negative relation between earnings management by using real operating activities and future returns. This finding is relevant for investors, particularly for the purposes of comparison and valuation of securities.
Diversity of yam bean ( Pachyrhizus spp. Fabaceae) based on morphoagronomic traits in the Brazilian Amazon
Authors: SILVA Edinei Santos da , FILHO Danilo Fernandes da SILVA , TICONA-BENAVENTE César Augusto
Published: July 2016

ABSTRACT Yam bean is a non-conventional horticultural crop adapted to the Amazon region. It presents edible roots, yet, its seeds contain cytotoxic components such as rotenone and pachyrhizin. The Instituto Nacional de Pesquisas da Amazonia has 64 yam bean genotypes in its germplasm bank, however, their diversity is unknown. The aim of this study was to assess the diversity of these genotypes using 10 morphoagronomic traits, plant height, number of secondary branches, shoot biomass, stem diameter, root biomass, number, length, diameter, length/diameter ratio (L/D), and shape. The accessions were planted on non-flooded land, Manaus, Amazonas (02º 59'48.2''S and 60º 01' 22.4''W) in completely randomized design with three replicates and three plants per plot spaced 0.5 x 1 m. The results showed significant diversity for all characters except for stem diameter and visual assessment of root shape. Biplot graphic explained 60% of the total variation, which identified that genotypes P44, P22 and P18 have high values for root yield (80-108 t ha-1), number of secondary branches (15-31) and shoot biomass (0.5-0.8 kg plant-1). Cluster analysis, considering 50% of relative Euclidean distance, revealed 15 major groups. We conclude that the genotypes assessed have wide diversity and some of them high root yield potential. This suggests that a yam bean breeding program can be successful for the yield of roots and seeds in the Amazonian region.

Published: July 2016

Abstract The crabwood (Carapa) represents an important source of natural resources. The objective of this work was to study the pollen morphology of the three species of Carapa (Meliaceae) registered in the Brazilian Amazon. The pollen grains were obtained from floral buds, pistillate and staminate flowers of Carapa guianensis, C. surinamensis and C. vasquezii. In order to explore the taxonomic implications of the pollen study for these species of Carapa, lactic acetolysis method was used for light microscopy study. Furthermore, the non-acetolyzed material was used in the study of the scanning electron microscopy. It was found that the three Carapa species present little variations in pollen morphology. Compared to the other species this study, Carapa vasquezii has higher values for the length and width of endoaperture; however, it has lower values for polar and equatorial diameter, equatorial diameter in polar view and apocolpium side.
THE CONSTRUCTION OF HEALTH CAUSAL RELATIONS IN THE BELO MONTE DAM CONTEXT
Authors: GRISOTTI MÁRCIA
Published: July 2016

Abstract The assessment of the impacts and risks to health is possible through studies on health (and environmental conditions) before and after the installation of dams. This condition allows the construction of causal relations in timescale and the transformation of data and information on scientific knowledge and public policy. In this article, it is analyzed the issues regarding the attribution of causality in the emergency (or decrease) of the diseases or injuries, taking as examples the relationship between migration and workers' diseases (brought or acquired), cases of syphilis in pregnant women, deaths due to violence (such as homicide) and traffic accidents in the context of the construction of the Belo Monte hydroelectric dam. It is analyzed the challenges for the construction of a complex network of causal relations, that incorporate the bio-physiological causes with other causes derived from human actions and political decisions (or omissions), in this specific context.

Abstract The environmental impacts of hydroelectric dams in Brazil are investigated in local and regional scales, for the last years. In this paper, we analyze the impact than the establishment of a hydroelectric dam has for the people and their spaces, with the comparative experiences occurred for the North and South of Brazil. We will focus on aspects related to the organization of families, social fight, the compensation and resettlement of people affected by the dam's construction, as well we take a look to the similarities between the two areas, with emphasis on aspects related to migration, mobility and landscapes. For this, we rely on research carried out on the river Uruguay (South), based on interviews, questionnaires and studies of primary and secondary sources, from 2007 to 2014 and also in a survey that is currently being held in Belo Monte area (North), which also uses primary and secondary sources, with fieldwork periods.
THE HISTORICAL TRAJECTORY OF THE BELO MONTE HYDROELECTRIC PLANT'S ENVIRONMENTAL LICENSING PROCESS
Authors: FAINGUELERNT MAÍRA BORGES
Published: July 2016

Abstract The purpose of this article is to present the historical trajectory of the hydroelectric plant of Belo Monte on the Xingu River. The plant, the third largest in the world and one of the most important works of the "Growth Acceleration Program" in Brazil, in the broader context, calls into question a developmental model and its implications for the energy planning in the Amazon region. The energy use of the Xingu River basin was also proposed during the military dictatorship in Brazil and, even after forty years is still emblematic for continuing to be full of controversies along its course. The initial premise of the research establishes that the lack of social and environmental impacts of the project followed the entire trajectory of Belo Monte and this case study brings important lessons for improvement of this instrument of Brazilian environmental policy.

Abstract In order to analyse the socio-environmental conflicts it is essential to pay attention to people's perception, because environmental problems can lead to different forms of conflict according to local economic and socio-cultural context. The main objective of this research is to determine the perception of the public about the different socio-environmental conflicts in the area of influence of the Mirador Project, the first project of large-scale mining in Ecuador. To do so, a representative sample of the general population was used to analyse how socio-environmental conflicts were perceived. Furthermore, the arguments and reasons that led people to take extreme positions on mining were also analysed. In both cases, the opinions about perceived conflicts at the time of the investigation and expected threats with the start of mining phase were examined.

Abstract Electrical energy is the basis of the lifestyle of contemporary society, whose main source in Brazil, is the dam, requiring the construction of major infrastructure projects. These projects drive contradictory social and political processes. In these processes, we glimpse the conflict between the Specific Purpose Entities (SPE), proponents of hydropower, and the Touched, representative parts of local populations forcibly displaced as a result of these works Movement of Affected by Dams. Having locus as the basin of Uruguay, southern Brazil, this article discusses the conflict through a "loop analysis" consists of hydropower and resettlement. We sought to understand the frequency and the motivations of those affected to participate politically in later demonstrations against their relocation hydropower. Therefore, we use a methodology that links qualitative and quantitative tools based on empirical research. The study enables us to understand that the primary motivator for participation of those affected in later for their resettlement mobilizations is human solidarity.

Published: July 2016

Abstract E-waste reverse logistics initiatives in important industrial economies like India, China and Brazil show that specific models of reverse logistics, adapted to local reality, are required in developing countries. This research objective is to discuss the main challenges and opportunities for the implementation of the reverse logistics Brazilian model for computers and cell phones. Methodological procedures included 21 in-depth interviews with multiple stakeholders including government, manufacturers, retailers, recycling companies, waste picker organizations and academics. Results show the importance of the new regulation to enhance the dialogue among the members of the electro electronic supply chain for the development of the Brazilian model of reverse logistics. However technological gaps in recycling e-waste within the country, its continental dimension, taxation challenges and conflicts between waste picker organizations and the industry are challenges for the Brazilian model success.
IS THE PANTANAL A PRISTINE PLACE? CONFLICTS RELATED TO THE CONSERVATION OF THE PANTANAL
Authors: CHIARAVALLOTI RAFAEL MORAIS
Published: July 2016

Abstract The book "Biodiversidade e ocupação humana do Pantanal mato-grossense: conflitos e oportunidades" brings to discussion a hardly citied issue in academic debates: the conservation of the Pantanal. A place pointed out by some authors as pristine. The book is divided into three main chapters. The first one is about the physical / biological feature of the region and the second covers the local historical occupation. Important publications about the Pantanal are sumerized well in both chapters. The last chapter describes current conflict between local people and Protected Areas over land use. However the authors misuse several findings about local settlements in the region, leading to imprecise conclusions. The lack of scientific accuracy in the main part of the book undermines its potential academic impact. Nonetheless this book triggers important debates about the conservation of the Pantanal, showing that it is not pristine and free of threats as is widely claimed.

Authors: Rohling Marcos , Valle Ione Ribeiro
Published: July 2016

Este trabalho tem como finalidade propor uma forma de considerar o conceito de justiça escolar, relativamente à questão da escola justa, à luz da teoria da justiça de Rawls e da teoria crítica de Bourdieu. Procurando um modo de conceber a justiça escolar que leve em conta os méritos teóricos dessas teorias, o artigo traz, primeiramente, uma reconstrução da crítica de Bourdieu à escola e ao seu papel perpetuador das desigualdades prévias à vivência escolar; em seguida, examina-se a teoria da justiça como equidade, de Rawls, dando especial atenção à consideração do significado da educação e da escola justa; por fim, inspirando-se na formulação dos princípios da justiça como equidade, são propostos dois princípios da justiça escolar.
Jongo e Educação Escolar Quilombola: diálogos no campo do currículo
Authors: Maroun Kalyla
Published: July 2016

Este artigo tem como objetivo analisar alguns diálogos, no campo do currículo, entre o jongo - prática cultural afro-brasileira - e a Educação Escolar Quilombola - nova modalidade de ensino institucionalizada no Brasil - a partir de um estudo de caso em uma comunidade quilombola (Santa Rita do Bracuí), localizada na região sul do estado do Rio de Janeiro, no município de Angra dos Reis. Para tanto, foi realizado um trabalho de campo de cunho etnográfico ao longo de dois anos, na perspectiva de uma descrição densa. Percebemos que as crianças e jovens quilombolas vêm construindo suas identidades étnicas por meio da inserção na prática do jongo, o que vem contribuindo e legitimando a demanda das lideranças políticas de Bracuí pela entrada dessa prática no currículo da escola local.
Religião e educação no Brasil: uma leitura em periódicos (2003-2013)
Authors: Setton Maria da Graça J. , Valente Gabriela
Published: July 2016

O artigo faz uma análise de textos que estabelecem interface entre religião e educação das áreas da antropologia, educação, história e sociologia. A investigação se localiza entre 2003 e 2013, em periódicos de seletiva política editorial. A partir da leitura, considera-se o Brasil um país fortemente religioso, ainda que as religiões tradicionais tenham perdido espaço. Ademais, é perceptível que ambas as esferas estejam marcadas por uma tensão em que demandas de ordem secular e religiosa estão presentes, sobretudo no plano das identidades políticas e culturais. A religiosidade do brasileiro apresenta-se forte enquanto prática de cultura, sendo a fé, para muitos, um alento para os momentos de vazios institucionais e existenciais, bem como instrumento identitário.
DO ESTRANGULAMENTO EXTERNO À MORATÓRIA: A NEGOCIAÇÃO BRASILEIRA COM O FMI NO GOVERNO FIGUEIREDO (1979-1985)
Authors: Salomão Ivan
Published: July 2016

RESUMO O processo de endividamento externo adotado nos anos 1970 esteve diretamente associado à necessidade de financiamento do II PND. A necessidade de legitimação do regime discricionário compeliu o governo a inserir a economia brasileira de modo imprudente no circuito financeiro internacional. Após o segundo choque do petróleo, em 1979, a política econômica da tecnocracia resumiu-se a administrar a crise do balanço de pagamentos. Estabeleceu-se, então, uma longa e hesitante negociação com o FMI e com os credores internacionais, e as divergências dela decorrentes ensejaram a decretação da moratória da dívida externa anos depois.
NÃO NEUTRALIDADE FISCAL, GASTOS PÚBLICOS E AGENTES HETEROGÊNEOS
Authors: Oliveira Victor Rodrigues de , Correia Fernando Motta
Published: July 2016

RESUMO O objetivo deste estudo é verificar se a política fiscal é não neutra em um ambiente de endogeneidade dos gastos públicos com agentes heterogêneos. Considerou-se que a política fiscal pode ser conduzida por dois instrumentos, a saber, os impostos lump-sum e os gastos públicos. Para alcançar o objetivo proposto construiu-se um modelo novo keynesiano a partir dos trabalhos de Blanchard (1985) e Leith e Thadden (2008). Os resultados do sistema dinâmico indicam que as políticas monetária e fiscal devam ser ativas, o que denota para a não neutralidade da política fiscal.
