REFINANDO EL TEMPO DE LA MÚSICA PARA UN EFECTO ERGOGÉNICO DURANTE EL EJERCICIO DE CICLISMO ESTACIONARIO
Authors: Aburto-Corona Jorge Alberto , Aragón-Vargas Luis Fernando
Published: December 2017

El efecto de la música durante el ejercicio ha sido estudiado desde muchas perspectivas, pero los resultados no han sido del todo claros, probablemente por la falta apropiada de control en la investigación. El propósito de este estudio fue medir el rendimiento físico en bicicleta estacionaria en un ambiente caluroso, en condiciones cuidadosamente controladas, modificando solo el tempo de la música. Diez estudiantes físicamente activos, con 24.5±3.6 años de edad (promedio ± desviación estándar), escogieron su música favorita para hacer ejercicio y realizaron una prueba de máximo esfuerzo en bicicleta. Durante las siguientes visitas al laboratorio, los participantes pedalearon a una cadencia de su preferencia y contra una resistencia constante (70% de la carga máxima) dentro de un cuarto de clima controlado (28.6±0.5°C y 65±3%FC), por 30 minutos en tres días diferentes, sin música (NM), con música tempo medio (MT-120ppm) o música tempo rápido (FT-140ppm) en orden aleatorio. Se registró el esfuerzo percibido (EP), la frecuencia cardíaca (FC) y el trabajo realizado (TR). No se encontró diferencia significativa entre condiciones en EP (4.47±1.52; 4.22±1.5; 3.83±2.06u.a. para NM, MT y FT, respectivamente, p=.162) ni FC (142.4±24.53; 142.6±24.37; 142.9±18.36lpm para NM, MT y FT, respectivamente, p=.994). Sin embargo, sí se encontraron diferencias en TR (43.4±19.02; 46.1±20.34; 47.1±20.97kJ para NM, MT y FT, respectivamente, p=.009); el análisis post-hoc demostró que esas diferencias en TR eran entre FT y NM. Al utilizar música del agrado de cada persona durante el ejercicio, los participantes mejoraron el rendimiento físico solo con tempo rápido de 140ppm.
Memória, patrimônio e inclusão social: um olhar a partir da teoria ator-rede
Authors: Sampaio Débora Adriano , Loureiro José Mauro Matheus , De Lima Izabel França
Published: December 2017

Desenvolve uma revisão de literatura com o objetivo de refletir sobre memória, patrimônio e inclusão social no âmbito da teoria antropológica, Ator-Rede (Actor Network-Theory). Aborda os conceitos de memória e de patrimônio na perspectiva das ciências humanas e sociais. A partir da conjectura geral sobre as noções de memória e patrimônio, considera a abordagem da Teoria Ator-Rede que amplia a ideia de ‘rede’ direcionando a relações, fluxos e mediações. Por meio da Teoria entendemos que uma rede não se reduz a um ator singular, mas é composta de elementos humanos e não humanos conectados, com características heterogêneas. Neste contexto, a memória e o patrimônio são abordados sob o ponto de vista da inclusão, a partir da compreensão interação advinda do interior das relações sociais, considerando a multiplicidade e a diversidade de fatores envolvidos, que produzem sentidos e significados diversos na perspectiva da ‘rede’. Portanto, essa reflexão nos permite ampliarmos o nosso olhar em torno da ideia de memória, patrimônio e inclusão, desafiando as reflexões atuais existentes a buscar outros sentidos e significados, analisados sob a fundamentação dessa Teoria.

Published: December 2017

Water ecosystems are constantly under the pressure of a high number of biotic and abiotic factors, and their action leads to the occurrence of fluctuations in species and populations. The specific response of organisms to external pressures leads to the reorganization of ecosystems, with qualitative and quantitative changes. The aim is to identify the microbial groups with the highest potential in the waste waters. Data were collected during 2015-16 in Bistrita. Identifying the bioindicators quality of microorganisms and their importance in ecosystems was done by comparing them with international databases. The use of microorganisms as bioindicators involves knowing the requirements for one or more environmental variables. The concept refers to the ability of microorganisms to accumulate pollutants. Flagellates are tolerant to acidity and react quickly and with sensitivity to environmental stress by inhibiting their movement. The multiplication of flagellates and filamentous bacteria is manifested through water disturbance and foam production.

Published: December 2017

In this study we wanted to obtain a fermented milk product from the kefir assortment with added chanterelle which are native mushrooms, because in our country is not such a product. We chose these mushrooms for their rich composition in essential amino acids, vitamins and mineral salts and which in turn are very consumed. The resulting product shows a high nutritional value and antioxidant properties due to the valuable compounds in the mushroom composition. The mushrooms were previously lyophilized and the resulting powder was added in different proportions, obtaining three samples. These samples were compared with a blank sample over a 12 days period by sensory and physicochemical point of view.
Plants that can be Poisonous for Cows. A Review
Authors: EL MAHDY Cristina , POPESCU Silvana , BORDA Cristin
Published: December 2017

Romania is blessed with a rich spontaneous flora, but some of the plants are toxic by their consumption in cattle, affecting the health, productions and endangering consumer safety. Sometimes even the consumption of small amounts causes poisoning with a broad extension: from mild, moderate to severe and with chronic or acute manifestations. Plant action is not similar. Taxus Buccata, Eupatorium spp. (E. rugosum, E. urticaefolium, E. ogeratoides) are cardiotoxic plants, but, Eupatorium spp. also acts through depression of the central nervous system; Datura stramonium (Jimson weed), Solanum spp. (nightshades), Atropa belladonna (belladonna), are plants with cholinergic blocking; haemolytic anemia is caused by Pteridium aquilinum (Bracken fern) and Equisetum (horsetail). The poisoning with cyanogenic principles occurs at Sorghum spp (Johnson grass, sudan grass); Elderberry consumption, Senecio spp. and Hypericum (St John’s wort) induces liver toxicity. Plants containing alkaloids outside their toxicity also have teratogenic action: Lupinus spp., Nicotiana spp, Conium maculatum, Veratrum album. However, some of these plants can be used in certain cows’ treatments.

The European plum (Prunus domestica L.) is one of the most important cultivated species among fruit trees in the world, and the dominant in Romania. Regarding the development of new plum cultivars derived from Prunus domestica, the following characteristics are taken into consideration most of the time: high yield performance, good quality fruits and last but not least, the resistance to PPV. “HoneySweet” is a transgenic clone of Prunus domestica transformed with Plum pox virus coat protein gene making it highly resistant to the virus. This study presents preliminary results on the chemical composition of HoneySweet transgenic plum and two conventional ones: Reine Claude d’Althan and Stanley. The most important nutritional factors were determined. HoneySweet had balanced individual carbohydrates content but lower soluble solids in comparison with the two conventional cultivars. Total lipids content in HoneySweet fruits was similar to Stanley, higher than in Reine Claude d’Althan. HoneySweet is distinguished by the highest total protein content. Similar amounts of magnesium and calcium were recorded in the three varieties. Overall, our preliminary results revealed that the quality and nutritional value of “Honey Sweet” genetic engineered plum is in the range of other valuable plum cultivars.

Published: December 2017

Geraniol and linalool have been found to be effective against foodborne microorganisms in vitro. However, due to their hydrophobic nature, it is difficult to achieve an even dispersion in foods with high water content resulting in dramatic loss of activity. The aim of the study was to fabricate geraniol or linalool nanoemulsions and investigate their effect against Escherichia coli K12, Listeria innocua and Pseudomonas lundensis in a meat simulation medium. The agar diffusion assay revealed that both geraniol and linalool had a potent antimicrobial activity against all bacteria. Dynamic light scattering showed that geraniol and linalool nanoemulsions had a mean diameter of 68.22±2.46 and 173.59±4.15 nm, respectively. Killing assay results showed that both nanoemulsions were able to significantly reduce E. coli and L. innocua counts by approx. 3 log CFU/ml. Ps. lundensis proved to be more resistant to both nanoemulsions showing a reduction of approx. 1.2 log CFU/ml,. Overall, this study showed that nanoemulsions loaded with geraniol or linalool represent a promising antimicrobial system to improve food preservation and food safety.

The distillates obtained from wine, both raw and aged, are highly appreciated alcoholic beverages due to the refinement and fineness that characterizes them. Romania’s viticultural conditions are very favourable for these products - which in the last centuries have made regions such as Cognac and Armagnac in France famous. In Romania the aged distillate of wine is called “vinars” and in the Republic of Moldova it is named “divin”. This study analyses how the main compositional parameters and volatile compounds are influenced by the raw material wine, distillation technology, distillation steps, removal of the lower-quality fractions (heads and tails). The raw material used to make the distillates was a mixture of two wines of Fetească albă and Fetească regală, harvest of 2015, from Iasi vineyard. The proposed experimental protocol consisted of the double distillation of a volume of 1000 L of raw material. For the distillation, a simple copper distillery with a deflector was used. From each 10 L of distillate obtained, samples were taken and analysed via gas-chromatography.In the first and second distillation, the largest amounts of acetic acid are found in the head. The highest concentrations of octanoic acid are recorded in tails, as does hexanoic acid. The product obtained after the first distillation recorded an average alcoholic strength of 33.5% vol, which increased after the second distillation, so that the final distillate has an alcoholic strength of 58.5% vol. Concerning the acid profile, the following can be concluded: Acetic acid can be considerably diminished with the removal of the head fractions; Octanoic, hexanoic and decanoic acids fall into the class of short chain fatty acids, can affect the organoleptic qualities but are easily esterify the resulting compounds giving pleasing odour; aging in oak or mulberry wood barrels of crude distillates to achieve the maximum potential is recommended.

Authors: MÎNDRU Marcel , PĂCURAR Ioan , ROŞCA Sanda , BILAŞCO Ştefan , PĂCURAR Horea
Published: December 2017

The Mociar Forest Reserve has a great scientific interest due to the age of the oaks ranging from 400-500 years, which is why it is included in the protected area category. Over time, a series of studies have been carried out on the occurrence of the oak drying phenomenon in the Mociar Forest in order to develop plans for measures to prevent and combat oak drying. The main reason for this was to analyze the physical and chemical properties of soils. Considering the direct influence of soil characteristics on the development of forest species within the Mociar Forest, we proposed the creation of nine soil profiles located in areas considered representative of the studied area and the identification of the main physical and chemical parameters in the laboratory stage (the soil pH, the nitrogen amount, the total humus and C:N ratio variation). According to the four factors analysed a GIS spatial analysis model has been developed in order to identify the favourability and soil restriction for forest species in the studied area. It was also sought to obtain an overall picture of the distribution of these parameters on their qualitative classes as well as on the distribution classes of specific, dominant forest species. This was made possible by the use of G.I.S. technology and specific geospatial interpolation and spatial analysis tools.

Published: December 2017

The aims of this study were to identify the status of repeat breeding syndrome (RBS) in a dairy farm, to establish the main cause of RBS and to reduce the number of RBS using the Ovsynch protocol. 20 cows were diagnosed with RBS using computer analysis of the herd and a specific diagnosis for the cause of RBS was attempted. Subsequently, they were divided into 2 groups: cows in group 1 (n=10) received no hormonal treatment while those in group 2 (n=10) were treated using the Ovsynch protocol. Artificial insemination and pregnancy diagnosis was performed in all cows. The 70% pregnancy rate obtained for Ovsynch showed that the hormonal effect as well as correct timing of insemination had a significant influence on RBS, pointing out towards the managerial factor as one of the main causes of RBS. The cow factor was also included, as endometritis, follicular cysts and anovulatory heats were diagnosed.

Published: December 2017

In this study we aimed to assess the efficiency of organic acids in different concentrations regarding pathogens as Salmonella, Listeria and Escherichia on beef, which can cause food borne illness in humans. The samples were sterilized using UV radiation for 30 minutes, afterwards being contaminated with 1 ml of microbial suspension (0.5 MacFarland). We used reference bacterial strains for Salmonella Enteritidis, Escherichia coli and Listeria monocytogenes. The samples were subjected to decontamination procedure by introducing 25mL of solution of lactic, acetic or citric acid in concentration of 1%, 2% and 3%. The results showed a reduction of initial pathogen load, ranging from 0.32 to 7.78 log CFU/g, depending on the type of acid, concentration and pathogen sensitivity. After decontamination, standardized methods have been used for the isolation of pathogenic germs. Based on statistical analysis we conclude that pathogens have a different sensitivity to the action of acid solutions, their sensitivity in ascending order being: Listeria monocytogenes, Salmonella Enteritidis and Escherichia coli. Among the organic acids, the most efficient was lactic acid, followed by acetic acid and less efficient citric acid. The greatest reduction of germs was determined by the concentration of 3%.

ABSTRACT The low-educated elderly are a vulnerable population in whom studying the role of white matter integrity on memory may provide insights for understanding how memory declines with aging and disease. Methods: Thirty-one participants (22 women), 23 cognitively healthy and eight with cognitive impairment-no dementia, aged 80.4 ± 3.8 years, with 2.2 ± 1.9 years of education, underwent an MRI scan with diffusion tensor imaging (DTI) acquisition. We verified if there were correlations between the performance on the Brief Cognitive Screening Battery (BCSB) and the Rey Auditory Verbal Learning Test (RAVLT) with DTI parameters. Results: The BCSB delayed recall task correlated with frontotemporoparietal connection bundles, with the hippocampal part of the cingulum bilaterally and with the right superior longitudinal fasciculus. The RAVLT learning and delayed recall scores also correlated with the hippocampal part of the cingulum bilaterally. Conclusions: Although preliminary, our study suggests that the integrity of white matter frontotemporoparietal fasciculi seems to play a role in episodic memory performance in the low-educated elderly. This finding opens opportunities to study potential targets for memory decline prevention in vulnerable populations.

Published: December 2017

ABSTRACT: Gene expression of ErbB1 and ErbB2, and immunostaining of EGFR (Her1) and Her2 (c-erbB-2) were evaluated in this study to ascertain whether these receptors are involved in the evolution of canine premalignant and malignant prostatic lesions, as proliferative inflammatory atrophy (PIA) and prostatic carcinoma (PC). With regards to the intensity of EGFR immunostaining, there was no difference between normal prostatic tissue and tissues with PIA or PC. In relation to Her2 immunostaining, there were differences between normal prostatic tissue and those with PIA and PC, as also differences between prostates with PIA and PC. There was no correlation between EGFR and Her2 immunostaining. ErbB1 gene product was detected in two normal tissue samples, in one with PIA, and in all samples with PC. ErbB2 mRNA was recorded in two canine samples with PIA, in all with PC, but was not detected in normal prostatic tissue. It was concluded that EGFR and Her2 play roles in canine PIA and PC, suggesting that those receptors may be involved in canine prostatic carcinogenesis.

Published: December 2017

ABSTRACT: An experiment was conducted to study the effects of two sources and dietary levels of selenium (Se) on performance, Se concentration and glutathione peroxidase activity in plasma and liver of piglets post weaning. A total of 126 weaned pigs male and female Large White × Landrace, at average body weight of 7.2±0.67kg were allotted to seven treatments in a randomized block design, with two Se sources (organic and inorganic), inclusion levels, two levels for the inorganic source (0.30 and 0.60ppm) and four for the organic source (0.15, 0.30, 0.45 and 0.60ppm) and one control diet without Se supplementation containing 0.095ppm, and six replicates of three animals per pen. The experimental period was 35 days post-weaning. The organic source contained 0.2067% (Se-yeast), and the inorganic 45.86% (sodium selenite) analyzed. Piglets that received supplemental Se had lower feed intake compared to those not supplemented. Furthermore, feed conversion was better with dietary supplementation of Se, and the organic source was better than the inorganic source at level of 0.30ppm. Plasma concentration of Se was higher (35.53%) in animals receiving dietary supplementation of this mineral, regardless of the sources studied. There was no effect of sources on plasma and hepatic Se, with the lowest values observed for the non-supplementation and organic Se at dietary level of 0.15ppm. There was a linear reduction of plasma GSH-Px activity with increased supplementation levels of organic Se, and the hepatic GSH-Px activity increased linearly with the increased supplementation, regardless of the source studied.
AS LÓGICAS DOS PRODUTORES INVISÍVEIS: SIGNIFICADOS CULTURAIS NA PRODUÇÃO AGRÍCOLA FAMILIAR

Published: December 2017

RESUMO A produção agrícola tem adotado padrões mundiais, orientada por uma lógica produtivista por meio da produção em larga escala, busca constante de melhora de desempenho, aproveitamento da terra e maximização dos lucros. Estes significados orientam as atividades dentro da comunidade de produtores (PRESS; ARNOULD; MURRAY et al., 2014), mas demonstram-se distantes das lógicas da agricultura familiar, construídas a partir da valorização de aspectos sociais e culturais. Dessa forma, este estudo tem como objetivo compreender a criação de significados culturais acerca da agricultura familiar e a forma como estes significados resultam na construção de lógicas distintas aquelas predominantes no agronegócio. Com base num referencial teórico acerca da construção de significados culturais, adotou-se uma abordagem exploratória por meio de um conjunto de entrevistas com pequenos produtores rurais. Os resultados forneceram três categorias chaves que permeiam a criação de significados na agricultura familiar: formação identitária dos produtores, significados dos alimentos e relações sociais. A análise integrada dos resultados indica a construção de lógicas envolvendo aspectos identitários, sociais, culturais e de produção particulares da agricultura familiar. Os resultados contribuem com o desenvolvimento de políticas públicas e mercadológicas alternativas aquelas predominantes no agronegócio e que respeitam os significados culturais produzidos internamente em grupos não hegemônicos na representação social do universo agrícola.

Published: December 2017

ABSTRACT Reductions in soybean yields are mainly linked to the occurrence of dry spells, which are becoming more frequent due to climate change. Thus, the aim of this study was to evaluate soybean cultivars irrigated with different water depths under center pivot. The experiment was conducted during the 2014/15 growing season, under center-pivot irrigation in Chapadão do Sul, MS, Brazil. The design was a randomized block in split plot with four replicates, where plots consisted of 4 water depths (0, 50, 75 and 100% of crop evapotranspiration - ETc) and the subplots of 6 soybean cultivars (NA 5909 RR, DM 5958 IPRO, Anta 82 RR, M 7110 IPRO, Desafio RR, M 7739 IPRO). The cultivar Desafio RR was the one that best responded to irrigation, increasing yield to 6174 kg ha-1 against 3798 kg ha-1 under rainfed condition. The highest yield under rainfed condition was obtained by the cultivar NA 5909 RR, reaching 4806 kg ha-1. This shows that some cultivars can respond positively to irrigation, resulting in increased yield, depending on the genetic characteristics of each one.

ABSTRACT Single or split nitrogen (N) supply can maximize the expression of wheat yield indicators. The objective of the study was to evaluate the greater N use efficiency on wheat yield indicators by the single and split N supply under favorable and unfavorable year conditions to the crop in succession system of high and reduced residual N release. The study was conducted in 2014 and 2015, in a randomized complete block design with four replicates in a 4 x 3 factorial, for N-fertilizer doses (0, 30, 60, 120 kg ha-1) and supply forms [full dose (100%) in the phenological stage V3 (third expanded leaf); split dose (70 and 30%) in the phenological stages V3/V6 (third and sixth expanded leaves, respectively) and; split dose (70 and 30%) in the phenological stages V3/R1 (third expanded leaf and early grain filling)], respectively, in soybean/wheat and maize/wheat cultivation systems. The highest N use efficiency for wheat yield was obtained with the single dose supply in favorable year of temperature and rainfall and with the split dose in the V3/V6 stages in unfavorable year, regardless of the succession system of high and reduced residual N release.

ABSTRACT The development of agriculture in the northeastern semi-arid region depends, at least in part, on the correct exploitation and efficient use of natural resources. The objective of this study was to evaluate the effects of the use of saline water on morphophysiological responses and sensory analysis of ‘Boa noite’ plants (Catharanthus roseus) in soil fertilized with bovine biofertilizer. A completely randomized design was used in the split plot arrangement, the plots being formed by the five irrigation water salinity levels (0.5, 2.5, 5.0, 7.5 and 10 dS m-1), and the subplots by two frequencies of application of the 150 mL pot-1 of liquid bovine biofertilizer (divided into one and five times), with five replicates. The analysed variables were: leaf gas exchange relative chlorophyll index, biometry, dry matter (leaf, stems, flowers and roots) and sensory analysis (general appearance and buyers’ preference). Quantitative (growth and physiological) and qualitative (sensory analysis) responses show that Catharanthus roseus plants can be produced using saline water at the level of 2.5 dS m-1, and the plants of this treatment were preferred by the judges in sensory analysis. Biofertilizer application frequency did not attenuate the effects of salinity. Therefore, the liquid bovine biofertilizer can be applied all at once, reducing costs.

ABSTRACT The aim of this study was to evaluate the growth of grafted guava cv. ‘Paluma’ subjected to different concentrations of salts in irrigation water and nitrogen (N) fertilization. The plants were transplanted to 150 L lysimeters and under field conditions at the Science and Agri-food Technology Center of the Federal University of Campina Grande, in the municipality of Pombal - PB. The experiment was conducted in randomized block design in a 5 x 4 factorial scheme, with three replicates, and the treatments corresponded to five levels of electrical conductivity of irrigation water - ECw (0.3; 1.1; 1.9; 2.7 and 3.5 dS m-1) and four N doses (70, 100, 130 and 160% of the N dose recommended for the crop). The doses equivalent to 100% corresponded to 541.1 mg of N dm-3 of soil. Irrigation water salinity above 0.3 dS m-1 negatively affects the number of leaves, leaf area, stem diameter, dry phytomass of leaves, branches and shoots . A significant interaction between irrigation water salinity and N fertilization was observed only for the number of leaves and leaf area at 120 days after transplanting. N dose above 70% of the recommendation (378.7 mg N dm-3 soil) did not mitigate the deleterious effects caused by salt stress on plant growth.

ABSTRACT Biological nitrogen fixation (BNF) efficiency can be increased by co-inoculation with bradyrhizobia and Azospirillum brasilense, allowing even greater uptake of water and nutrients, leading to higher yields. Thus, this study aimed to evaluate the technical and economic viability of soybean in the Cerrado, according to the cultivars and co-inoculation with Azospirillum brasilense. The experiment was conducted in Selvíria, MS, in no-tillage system, in Oxisol, arranged in a randomized block design in a 2 x 2 factorial scheme with two cultivars (‘Potência’ and ‘Valiosa’), with and without co-inoculation with Azospirillum brasilense in the seed. Co-inoculation with A. brasilense increases grain yield in the cultivars ‘Potência’ and ‘Valiosa’, being economically viable. However, using the cultivar ‘Potência’ co-inoculated led to the highest profitability.
Programa Mais Médicos: elementos de tensão entre governo e entidades médicas
Authors: Alessio Maria Martins , Sousa Maria Fátima de
Published: December 2017

Em 2013, chegaram os primeiros médicos pelo Programa Mais Médicos. O seu processo de implantação foi cercado de disputas judiciais e embates ideológicos advindos de médicos brasileiros e suas entidades representativas. A iniciativa de criação do programa foi creditada pelas entidades médicas como uma medida unilateral do Governo Federal, eleitoreira e sem planejamento. O artigo resgata o processo histórico que deu origem ao Programa Mais Médicos, destacando a tensão entre governo e entidades médicas. Trata-se de estudo exploratório com pesquisa bibliográfica e documental. Analisando dados e tendências nacionais e internacionais e discursos de médicos e suas entidades representativas, é possível inferir que o programa não está sendo compreendido na sua totalidade, que vai além da provisão imediata de médicos. Além disso, o papel regulador do Estado para cumprir a Constituição Federal está sendo confundido com interferência na autonomia da profissão médica.
Marketing of food and beverage in Brazil: scientific literature review on regulation and self-regulation of advertisements
Authors: Kassahara Aline , Sarti Flavia Mori
Published: December 2017

The effects of marketing strategies for promotion of foods and beverages have been investigated due to its potential impacts on populations’ food choices, particularly among children and adolescents. The paper presents an academic literature review on regulation and self-regulation of food and beverage advertisements in Brazil, based on search performed in electronic databases. Majority of studies were based on law analysis or qualitative study of advertisements. There are sufficient evidences on the need for government regulation of advertisements addressed to children and adolescents complementarily to institutional self-regulation in order to tackle ethical transgressions on food and beverage advertisements identified in Brazil. Additionally, there should be imposition of rigorous penalties for noncompliance to ethical rules and proposition of incentives towards actions encouraging healthy food consumption patterns, in order to comprise an actual system for promotion of public health.
Ideias, imagens e crenças na produção de políticas públicas: o caso do Programa Mais Médicos
Authors: Ferla Alcindo Antônio , Pinto Hêider Aurélio , Possa Lisiane Bôer , Trepte Renata Flores , Ceccim Ricardo Burg
Published: December 2017

O artigo analisa as manifestações dos candidatos a cargos eletivos de âmbito federal e estadual, durante o processo eleitoral do ano de 2014, quanto ao Programa Mais Médicos, presentes na mídia comercial impressa e on-line, identificando ideias, imagens e crenças sobre tal política pública. Um mapeamento do posicionamento dos candidatos objetivava identificar sentidos e significados sobre o programa, explicitando a descrição de problemas e soluções acerca da provisão de trabalhadores no Sistema Único de Saúde. Os dados obtidos demonstraram que o tema do provimento emergencial de médicos extrapolou o subsistema ou campo da Saúde e foi assumido como agenda no sistema político. Tanto os candidatos manifestamente favoráveis ao programa quanto aqueles que faziam críticas expressaram publicamente a imagem de um programa necessário e uma estratégia com a qual estariam comprometidos. O programa ampliou muito a visibilidade da agenda setorial da Saúde.
THE RIO DOCE MINING DISASTER IN BRAZIL: BETWEEN POLICIES OF REPARATION AND THE POLITICS OF AFFECTATIONS
Authors: Zhouri Andréa , Oliveira Raquel , Zucarelli Marcos , Vasconcelos Max
Published: December 2017

Abstract This article analyses the policies of affectations in the context of the disaster which occurred in late 2015, when an iron ore tailings dam ruptured, affecting thousands of families in the Rio Doce River Valley, in the southeast of Brazil. The paper discusses the challenges faced by victims of the disaster, given that the ‘affected person’ as a social subject goes through a dramatic process of forced sociability, forged in political processes and bureaucratic demands which are alien to her/his world. As a consequence, the claims of victims are transmuted by the rationalities and techniques of corporate management, therefore disabled and re-codified by taxonomies which define forms of damage reparations, as well as modes of reconstruction of their way of life. From an anthropological perspective, we examine the struggle between the objectification imposed by the policy of affectation and the political subjectivation of actors compulsorily brought to contentious settings over the control of their own destiny.
“IT WAS NO ACCIDENT!” THE PLACE OF EMOTIONS IN THE MOBILIZATION OF PEOPLE AFFECTED BY THE COLLAPSE OF SAMARCO'S TAILINGS DAM IN BRAZIL
Authors: Losekann Cristiana
Published: December 2017

Abstract This article presents the dynamics of collective action and the construction of claims of people affected by the rupture of a tailings dam of the Samarco mining company in Minas Gerais, Brazil in November, 2015. Our analysis focuses on affected people in Espírito Santo State and is based on interviews, observation, participant observation and a series of meetings with affected people during the year following November, 2015. We describe initial processes of mobilization which involve various actors and interactions marked by emotions and by the creation of affective bonds. We draw on a culturalist framework of social movement studies to understand the emotional mechanisms in play in the construction of collective action, in particular, claims for justice (Jasper 1997; Gamson 1992; Goodwin, Jasper and Polletta 2009; Johnston and Klandermans 1995). We conclude that emotions play fundamental roles in the process of mobilization. The manner in which the disaster on the Rio Doce was felt by activists constituted a critical emotional event.
MINING-RAILROAD-PORT: “AT THE END OF THE LINE”, A CITY IN QUESTION
Authors: Sant'Ana Júnior Horácio Antunes de , Alves Elio de Jesus Pantoja
Published: December 2017

Abstract The effects of iron ore mining carried out in the Southeast of Pará state, located in Northern Brazil, are present alongside the Estrada de Ferro Carajás (Carajás Railroad), especially in the city of São Luís do Maranhão, located in Northeastern Brazil, which is the port of export. Combined with the processes of mining, transport and exportation of the iron ore, infrastructure projects, factories, extensive cattle farming and monoculture, and lumber exploitation damage the landscape of the Eastern Amazon region and impair the local traditional way of life. Regarding the city of São Luís, such effects are more strongly felt in the rural zone, where they result in environmental conflicts. The present article discusses the relationship between the extended effects of mining and the backlash provoked by them in São Luís. Such a discussion comprises, among other subjects, the demands for Extractive Reserve, ways to guarantee the control over the territory, debates on urban legislation, opposition to the building of port terminals.
Rainhas, princesas e donas: formas de poder político das mulheres na África Oriental nos séculos XVI a XVIII
Authors: Rodrigues Eugenia
Published: December 2017

Resumo Este artigo discute o papel das mulheres enquanto actores políticos na região correspondente hoje, grosso modo, a Moçambique, mas também a parte do Zimbabué, Zâmbia e Maláui, entre os séculos XVI e XVIII. Partindo da literatura sobre os estados pré-coloniais e de documentação portuguesa, mostra-se como as mulheres tiveram uma participação activa nas estruturas políticas, agindo como conselheiras, governando nos interregnos, assumindo a chefia de grupos e territórios. As formas de autoridade que as mulheres desenvolveram nestas sociedades, e que se estenderam à sociedade colonial, exigem estudos mais aprofundados.

Resumo Atentando para a narrativa de Mhudi – An Epic of South African Native Life a Hundred Years Ago, publicado em 1930 pelo político e jornalista sul-africano Sol Plaatje, analiso como os impactos das políticas segregacionistas que se intensificaram após a consolidação da União Sul Africana, em 1910, entrelaçam-se a aspectos fundamentais desse romance histórico. Na construção de sua personagem principal, Mhudi, Plaatje projeta não apenas um protagonismo feminino negro desejado para a nação sul-africana, mas também retoma aspectos da memória política sul-africana na tentativa de tecer novas possibilidades para as relações raciais naquele país.
Orar, ensinar ou agir. As diversas formas de cumprir o Carisma de Sion
Authors: Brito Angela Xavier de
Published: December 2017

Resumo Fundada pelo Pe Ratisbonne em 1842 para converter os judeus, o carisma de Sion oscila entre a oração, o ensino e a ação direta. Sion foi mais conhecida por seus internatos até os anos 1960, quando a incorporação das Ancelles (1937) e a virada ecumênica a fizeram retornar a suas origens. A pesquisa histórica realizada nos arquivos de Paris mostra que as tarefas educativas levaram as Irmãs a negligenciar o carisma original até o Concílio Vaticano II (1962-65), quando confiaram seus colégios a leigas, saíram para se formar em teologia e estudos bíblicos e participar do movimento de estima mútua com relação ao povo judeu.
A Igreja Católica e suas instituições de Ensino Superior
Authors: Arduini Guilherme Ramalho
Published: December 2017

Resumo Este artigo visa apresentar um mapa das instituições de Ensino Superior (IES) de propriedade de algumas organizações da Igreja Católica, com o objetivo de fornecer subsídios para uma discussão sobre a laicidade a partir de um ramo importante do sistema educacional brasileiro, dado que o ensino universitário concentra boa parte dos esforços das instituições religiosas, ao mesmo tempo em que é responsável pela formação profissional e pela pesquisa em seu nível mais avançado. As IES confessionais, vivendo entre as expectativas traçadas por uma burocracia religiosa – tais como angariar fundos para seus mantenedores ou produzir conhecimento em temas do interesse destes – e as exigências dos órgãos de controle de ensino e pesquisa universitários, revelam o perfil do investimento realizado através de dados como: o tipo de curso privilegiado ou as áreas de conhecimento com maior número de ofertas. Além disso, será possível estabelecer parâmetros de classificação que permitam descrever uma topografia dessas instituições, tanto no sentido literal (onde estão e com que perfil) quanto no sentido bourdieusiano do espaço que seus administradores ocupam no campo universitário brasileiro. O fato de a maioria das instituições analisadas possuir exclusivamente cursos de graduação – e de Pedagogia e licenciatura em quase todas –permite à pesquisa afirmar que ocupam uma posição dominada em termos de inovação científica e, ao mesmo tempo, dominante na divulgação do conhecimento existente.
As congregações religiosas femininas francesas frente às opções de Secularização ou Exílio na França da Terceira República
Authors: Colombo Maria Alzira da Cruz
Published: December 2017

Resumo O artigo busca analisar o modo como as religiosas francesas enfrentaram, no período histórico correspondente à Terceira República (1870-1940) da nação francesa, processos adversos de fechamento dos institutos, da secularização e do exílio, os quais, de certa forma, concorreriam posteriormente para o desenvolvimento educacional feminino das nações onde elas se instalariam. Particularmente, o texto aborda o desenvolvimento e a expansão da Congregação Nossa Senhora de Sion, que chegou ao Brasil em 1888, como representativa das religiosas francesas que, tendo emigrado para vários países, contribuíram para a educação das jovens.
