Resumo Este artigo relata a experiência dos editores de uma revista de Administração e Negócios na Amazônia, considerando a contribuição desse periódico para o avanço científico acadêmico com foco no desenvolvimento sustentável. O objeto do estudo é a Revista de Administração e Negócios na Amazônia (Rara). A Rara foi criada por pesquisadores do Centro de Estudo Interdisciplinar em Desenvolvimento Sustentável da Amazônia (Cedsa), cujo grupo de pesquisa é vinculado ao Programa de Pós-Graduação em Administração da Universidade Federal de Rondônia (PPGA/Unir). O estudo tem abordagem qualitativa, de natureza exploratória, com o objetivo de descrever a trajetória da revista. Os procedimentos foram orientados a relatar a experiência de seus editores. Utilizou-se como base de dados o site da própria revista. Os dados transformados em informações serviram de base para analisar a contribuição do periódico para o avanço científico acadêmico na Amazônia. Descrevem-se as estratégias de criação, editoração, penetração no âmbito acadêmico e avanço da Rara, pontuando a visão e as perspectivas de seus editores. Avaliamos que a iniciativa é pertinente e vem contribuindo com o desenvolvimento da Amazônia, no entanto, ainda se ressente de maior participação na produção científica de autores residentes nos estados da região Norte, bem como do baixo nível de qualidade nos trabalhos submetidos. Concluímos que o esforço de editoração para manter um periódico quadrimestral retrata a satisfação dos editores em contribuir com a disseminação do conhecimento e oferecer aos pesquisadores e acadêmicos da Amazônia e da comunidade científica como um todo um veículo para compartilhar suas reflexões e resultados de pesquisa sobre a Região.
Revistas Científicas em Administração: o papel histórico da Revista de Administração de Empresas (RAE) na construção do campo acadêmico em Administração no Brasil
Authors: Tonelli Maria José
Published: November 2018

Resumo Este artigo analisa o papel histórico da Revista de Administração de Empresas (RAE) na construção do campo acadêmico em Administração no Brasil, com base nos artigos, nos editoriais e nas resenhas publicadas a partir de sua criação, em 1961. A RAE surgiu como o periódico que introduziu os primeiros modelos de gestão a ser seguidos. Trata-se de uma nova linguagem, não apenas de formas de organizar as vendas ou a produção, de uma nova mentalidade que propõe uma organização social distinta. São características relevantes da RAE, desde sua criação, a divulgação de novas áreas do conhecimento em Administração e a publicação das primeiras pesquisas empíricas sobre a realidade brasileira. Os primeiros números da RAE indicam: i) a presença de autores estrangeiros, vários vinculados à Michigan State University (MSU), instituição que participou da fundação e do desenvolvimento da Escola de Administração de Empresas de São Paulo da Fundação Getulio Vargas (FGV EAESP); ii) os primeiros artigos de áreas temáticas da Administração, em especial, Marketing, Finanças e Comportamento Organizacional; e iii) o contato dos professores brasileiros com uma literatura internacional atualizada, especialmente norte-americana, no campo da Gestão. Ao lado de textos que tratam de práticas administrativas, a RAE também é um espaço para debates político-sociais e artigos reflexivos e críticos.

ABSTRACT This study had the objective of comparing two methodologies of sampling, Simple Random Sampling (ACS) and Stratified Random Sampling (ACE) to determine the optimum number of roundwood samples to obtain the moisture content of the population. In order to achieve this goal, different percentages of allowable error (5,10,15 and 20%) were considered for each sampling methodology. In the conduction of this study, the samples were randomly taken from a lot of 250 steres of wood, 144 roundwood of three meters of length and distributed in four classes of diameter. Later, the moisture content of these samples was determined. And, from these values, the population estimates (average, standard deviation, variance, coefficient of variation, and standard error) by ACS and ACE methods, helped to determine the optimum number of roundwood (n) to be sampled from different percentages of allowable error adopted in this study at 95% probability. According to the results, the amount of roundwood to be sampled from ACS for each allowable error 5, 10, 15 and 20% was respectively 214, 55, 25 and 14. For the ACE (proportional allocation) the amount of roundwood was 141, 35, 16 and 9 for ACE (optimal allocation) this number was 136, 34, 15 and 8. It was concluded that the most indicated sampling method for this study, considering the allowable error, was the ACE method.

ABSTRACT The conversion of areas cultivated with sugarcane into eucalyptus forests can promote improvements in the physical, chemical and biological properties of the soil. Within this context, the aim of this study was to evaluate the changes in the stocks and levels of carbon and nitrogen and soil-aggregate stability in an area of transition from sugarcane to eucalyptus in the State of Alagoas, Brazil. The study was carried out on a rural property, located in the district of Atalaia. The systems under evaluation consisted of four areas, one cultivated with sugarcane for approximately 20 years, taken as the reference area for the study, and three adjacent areas cultivated with eucalyptus forest, at 1, 3 and 6 years of age. Bulk density, the levels and stocks of carbon and nitrogen, and the soil aggregation index were all determined. The conversion of a sugarcane plantation under conventional tillage with straw burning into eucalyptus plantations promoted an increase in the levels and stocks of carbon and nitrogen in the soil; it also reduced bulk density and increased the water stability of aggregates. The results show that the conversion of sugarcane into eucalyptus in the Atlantic Forest region of Alagoas may be an alternative for promoting carbon sequestration and improving soil quality.

Published: November 2018

ABSTRACT Sesbania punicea (Cav.) Benth. has been recommended for the recovery of degraded areas. This study aimed at verifying the effect of salinity in the germination of S. punicea seeds in different hydric and luminosity conditions and assessing the influence of salinity and flooding on the growth and concentration of photosynthetic pigments. After the morphometric measurements of the fruits and seeds, we performed germination tests in different salt concentrations (0,5, 10 and 15gL-1 NaCl), keeping the seeds in a humid substrate (normoxy) or submerged (flooding), in the presence or absence of luminosity. There was a decrease in the percentage of germination and germination speed index (GSI) of seeds that were kept submerged in the dark. The average germination time (AGT) decreased up to the concentration of 10gL-1NaCl when the seeds were submitted to submersion in the presence of light. The growth and the production of leaves of seedlings exposed to flooding decreased as the salt concentration increased. The concentrations of photosynthetic pigments of seedlings of S. punicea did not differ among the treatments. Therefore, the colonization and occupation of new degraded areas by S. punicea may be limited by the presence of salts concentrations in the soil.
A STUDY OF THE PHYSICO-MECHANICAL PROPERTIES IN SHORT BLEACHING SEQUENCES
Authors: Ferraz Ana Paula Almeida , Ventorim Gustavo
Published: November 2018

ABSTRACT The kraft pulp of Eucalyptus spp. is relatively easy to be bleached. Therefore, studies have been carried out to reduce the number of stages of bleaching in the plant and minimize process costs. The present work aimed to evaluate the use of two short bleaching sequences in the physico-mechanical properties of cellulosic pulp as well as to compare these values to the ones obtained by usual bleaching sequences. The four bleaching sequences were ECF (elemental chlorine free), D0(E+P)D1P, AHTD0(E+P)D1P, and AHTDP and AHTD (PO). For each bleaching sequence the brightness, brightness reversion and total cost of reagents were evaluated. Physical and mechanical analyses were performed according to the methodologies of the Technical Association of the Pulp and Paper Industry (TAPPI, 2002). The AHTD (PO) sequence showed higher brightness, less brightness reversion, lower total cost and better smoothness compared to the reference sequences. However, it had a lower tear index and a lower compression index. The AHTDP sequence did not reach target brightness, however, it presented brightness reversion and lower total cost than the reference sequences. The AHTDP sequences showed high compression and smoothness, but presented a low compression index.
Dedução do limite de Chandrasekhar: uma abordagem didática dos trabalhos originais do autor
Authors: Evangelista Edgard de F. D.
Published: November 2018

Resumo Os atuais modelos de evolução estelar estabelecem que estrelas possuindo até cerca de oito vezes a massa do Sol dão origem a anãs brancas no final de suas vidas. Na década de 1920 surgiram trabalhos que descreviam tais objetos como formados essencialmente por um gás de elétrons e núcleons, de forma que a força de sua pressão de degenerescência equilibrava a contração gravitacional, originando corpos estáveis e de alta densidade. Na década de 1930 Subrahmanyan Chandrasekhar lançou sua abordagem ao problema das anãs brancas em artigos onde ele deduziu as densidades e a massa máxima permitida para essas estrelas. Tal valor máximo para a massa é hoje conhecido como limite de Chandrasekhar e o objetivo aqui é analisar os trabalhos originais de seu descobridor, mostrando de forma didática os passos que levaram à dedução desse importante resultado.
“A Detour in Longing”: Gender, Sexuality and Lesbian Desire in Carla Trujillo’s What Night Brings and Emma Pérez’s Gulf Dreams
Authors: Gouvêa Nathália Araújo Duarte de
Published: November 2018

Abstract: Questions of gender and sexuality have oftentimes been portrayed as taboo in traditionalist conservative societies. Gloria Anzaldúa claims in Borderlands/La Frontera (1999) that “she [the lesbian of color] goes against two moral prohibitions: sexuality and homosexuality. The Chicana lesbian, as a matter of survival and motivated by sexual impulses, struggles to surpass the passive role repression assigns to her and refuses to accept the heteronormative rule. In the present paper, I investigate how the narrative strategies and cultural references bring to surface the emotions and experiences that form subjectivity and sexual desire in Emma Pérez’s Gulf Dreams (1996) and Carla Trujillo’s What Night Brings (2003). Such transgressive narrators are of different ages and thus undergoing different maturity processes, but they begin both novels as young Chicana women attempting to explore their sexuality and uncover their own prohibited desires while becoming aware of the patriarchal and machista system in which they are inscribed. Here female sexuality and lesbian desire intertwine. The chosen novels enable a debate on women’s sexual development and exploration and society’s influence, judgement and punishment on female sexuality. Writings of Gloria Anzaldúa, Cherrie Moraga, Carla Trujillo, Emma Pérez and other feminist Chicana critics aid this analysis.
A Feminist Politics of Ambivalence: Reading with Emma Goldman
Authors: Hemmings Clare
Published: November 2018

Abstract: Feminist theory worldwide is confronting - perhaps as it always has done - a series of deep challenges. On the one hand, awareness of gender and sexual inequalities seems high; on the other, co-optation of feminism for nationalist or other right-wing agendas is rife. On the one hand, feminist social movements are in ascendancy, on the other there is a continued dominance of single issue feminism and a resistance to intersectional, non-binary interventions. If we add in the collapse of the Left in the face of radical movements such as those underpinning Brexit and Trump (and the frequent blaming of feminism for fragmentation of that Left) then it is hard to know what to argue, to whom, and for what ends. In the face of such claims it is tempting to respond with a dogmatic or singular feminism, or to insist that what we need is a shared, clear, certain platform. I want to argue instead - with Emma Goldman (anarchist activist who died in 1940) as my guide - that it can be politically productive to embrace and theorise uncertainty, or even ambivalence, about gender equality and feminism.
The History of Feminism and Doing Gender in India
Authors: Pande Rekha
Published: November 2018

Abstract: The present paper looks at the historical background of the rise of feminism and women’s movement and doing gender in India. Not only in India but all over the world there has been a close link between feminism and the women’s movement, each inspiring and enriching the other. In the Indian context, while the women’s movement is a much earlier phenomenon, the term Feminism is a modern one. Feminism comprises a number of social, cultural and political movements, theories and moral philosophies concerned with gender inequalities and equal rights for women. In the pre-independence era, the women’s movement began as a social reform movement in the 19th century. At this time, the western idea of liberty, equality and fraternity was being imbibed by our educated elite through the study of English and the contact with west. This western liberalism was extended to the women’s question and was translated into a social reform movement. In the post-Independence period during the first few decades, the major concern was for overall economic growth. This was immediately followed by another decade, which witnessed an increased concern for equity and poverty alleviation. Gender issues were subsumed in poverty related concerns and there were no such specific programs, which aimed at women. In the post-independence period, the women’s movement has concerned itself with a large number of issues such as dowry, women’s work, price rise, land rights, political participation of women, Dalit women and marginalized women’s right, growing fundamentalism, women’s representation in the media etc. and a large number of Non-Government organizations have taken up this issue. Women’s studies and now Gender studies is also an off shoot of the long history of women’s movement in India. Various women’s studies Centres have been set up and today again these are at the brink of disappearing from the radar and there is a struggle which is now going on. Though a lot needs to be achieved and there are various impediments in making this reality available to a large section of women, the women’s movement has brought women’s issues center stage and made them more visible.
Human Rights and Violence Against Women: Campo Algodonero Case
Authors: Paula Dandara Oliveira de
Published: November 2018

Abstract: The present article seeks to analyze human rights from a gender perspective. To do so, it goes back to the past to explain the development of the society of rights and women's rights. The analysis starts from the premise that human rights are social products and therefore will reflect and represent the values and interests of the society that produced them, in this case, capitalist society. One of the values of this society is patriarchy and the idea of the superiority of men as a social actor in relation to women. This value is represented in human rights that nevertheless have universality as one of its characteristics: the idea that all people are subjects of such rights independently of any identities. Therefore, the legal text in which human rights were coined affirms an equality that does not exist in practice, since women are violated and their rights are violated every day, in addition to the gender inequality present throughout the world. As an example and materialization of this reality, the Campo Algodonero Case, introduced to the Inter-American Court of Human Rights, appears as the first case of the Court to mention femicide, showing the vulnerability of women’s life and integrity.

NOTAS SOBRE AUTONOMIA E DESQUALIFICAÇÃO SOCIAL DE MULHERES PROSTITUTAS
Authors: Diniz André Geraldo Ribeiro , Mayorga Claudia
Published: November 2018

Resumo Os discursos que concebem as prostitutas como vítimas são tensionados, por elas, pela recorrente afirmação de suas autonomias. A pesquisa aqui apresentada se deu a partir de imersão na Zona Boêmia da Rua Guaicurus, na cidade de Belo Horizonte, e de entrevistas com oito mulheres prostitutas. Apresentamos alguns mecanismos psicossociais que impedem o acesso das prostitutas ao circuito instituído de reconhecimento social, analisando a associação desses mecanismos com experiências de enfrentamento e resistência a dinâmicas de desqualificação social. As narrativas das prostitutas entrevistadas nos dão pistas de que suas trajetórias se constroem entre sujeição e resistência à sujeição, heteronomia e afirmação de autonomia. A ambiguidade das dinâmicas sociais lhes permite interpelar os efeitos destrutivos da subalternidade e, como efeito disso, elas disseminam no tecido social outros saberes sobre suas condições de vida.

Published: November 2018

Resumo O presente artigo tem como objetivo explorar as potencialidades do método da cartografia de Deleuze e Guattari no âmbito das redes digitais, levando em conta o advento das mídias locativas e das tecnologias de geolocalização que fazem surgir os espaços híbridos, nos quais a experiência de se movimentar no espaço geográfico coincide com o movimento pelo ciberespaço. O artigo discute as possibilidades de associação da cartografia com outras estratégias metodológicas, como a flânerie e os diários de bordo, com o intuito de fazer frente à complexidade dos processos de subjetivação que são atravessados hoje pelo acoplamento cada vez mais íntimo com as tecnologias digitais. Exploramos, enfim, estratégias que podem ser pensadas para fugir às estrias de um espaço digital cada vez mais dominado pelo controle e pela vigilância, evidenciando como a atitude cartográfica pode nos auxiliar a desfazer os mapas, em direção a processos de criação e singularização.

Abstract Introduction In order to simplify the technique, reduce the time required for direct adhesive restorations, bulk-fill resin composites have been developed be applied in bulk placement up to 4 mm increments. Objective Evaluating the color change (ΔE) and the microtensile bond strength (μTBS) of bulk fill resin composites (BFRC) to dentin after the immersion in regular beverages and the application of bleaching systems. Method Forty-five human molar teeth were randomly distributed in three groups according to the filling material (n=15): Filtek Bulk Fill, Tetric N Ceram Bulk Fill and Filtek Z100. The restored teeth were immersed in coffee, wine and distilled water (n=5) for 72 hours. The color parameters were measured using a spectrophotometer, having as basis the CIE L*a*b*, before and after tooth staining and application of bleaching processes. Subsequently, the teeth were sectioned to obtain the specimens for the microtensile testing. The ΔE values were analyzed applying the Kruskal-Wallis and the Wilcoxon tests, and the μTBS values were analyzed applying the ANOVA and the Bonferroni tests (p<0.05). Result There were no significant differences in the ∆E values when comparing the BFRCs to the conventional resin composite (CRC) in most of the experimental groups. The ∆E values did not present significant differences before and after the application of bleaching processes for all the tested resin composites. The BFRCs presented higher μTBS values than the CRC after exposure to distilled water, wine and bleaching agent. Conclusion The studied BFRCs presented similar color stability to the CRC. The BFRCs presented higher bond strength to the dentin than the CTC in most of the evaluated conditions. The bleaching agent was not effective in whitening the stained restored teeth.

Abstract Introduction The color stability of resin cements, whether dual-pre-cured or photopolymerizable, as well as the color of the dental substrate, are fundamental for the aesthetic success of ceramic restorations, since the ceramic presents a high level of translucency due to its small thickness. Objective The aim of this in vitro study was to evaluate the color of a resin cement light polymerized by different light sources and immersed in potentially staining beverages. Material and method Were made 42 specimens of resin cement Variolink-Esthetic (2×6mm) (n=7), being half polymerized with LED light (F1) and half with Halogen light (F2). The specimens were stored in artificial saliva at 37 °C±1 °C. After 24 hours, they were polished with abrasive discs, and divided for the purpose of being submitted to the different solutions for 2 minutes per day, for 28 days, as follows: S1 – Coca-Cola; S2 – Red Wine; and S3 – Distilled Water (Control). Five color readouts were taken: T0 – initial; T1 – 7 days; T2 – 14 days; T3 – 21 days; and T4 – 28 days; with a spectrophotometer (Model SP62S). The color change data (ΔE*) were submitted to statistical analysis, ANOVA and Tukey (p≤0.05). Result Analyzing the factor solution, S2 (5.89 (±0.02)), produced a higher ΔE* value than S1 (3.79 (±0.02)) and (S1), a higher value than S3 (1.41 (±0.02)). Analyzing the factor light source, F2 (4.05 (±0.12)), produced a higher ΔE* value than F1 (3.33 (±0.12)). When analyzing the factor time, ΔE* values were found to increase gradually over the course of time: T1(2.36 (±0.08)); T2(3.27 (±0.08)); T3(4.06 (±0.08)); and T4(5.09 (±0.08)). Conclusion It was concluded that red wine produced a greater color change; Halogen light promoted highest degree of pigmentation; and the longer the time of immersion, the greater the color change of the material.

Published: November 2018

ABSTRACT: Leaf-cutter ants (Hymenoptera: Formicidae) have evolved as dominant herbivores on the American continent. These social insects remove the leaves of economically important plant species to maintain their colony’s food reserves, the symbiotic fungus Leucocoprinus gongylophorus, a basidiomycete. Such fungus can be used for applications of fungicide molecules from metabolites generated by symbiont bacteria (Xenorhabdus and Photorhabdus) from entomopathogenic nematodes (Steinernema and Heterorhabditis). Through isolation and multiplication in tryptic soy broth (TSB) medium of the bacteria Xenorhabdus szentirmaii isolated PAM 25, we conducted laboratorial tests using treatments with 10, 25, and 50% of the metabolites obtained in the sixth day of cultivation. The treatments were centrifuged and filtered to generate a supernatant, which was diluted in potato + dextrose + agar (PDA), to verify the consequences of exposure to the fungus L. gongylophorus in Petri dishes. To confirm metabolite efficiency, the control treatments in PDA only and mixed (PDA+TSB) media were conducted simultaneously for 14 days. We observed total inhibition of the symbiont fungus in both the 25 and 50% dilutions during the first days of the tests. Our results support that these metabolites have inhibitory effect on the development of symbiont fungus of leaf-cutter ants.

Published: November 2018

ABSTRACT: With the aim of developing tools for simultaneously managing Rhynchophorus palmarum and the coconut stem bleeding disease, we evaluated the effects of the insecticide thiamethoxam and the fungicide cyproconazole on R. palmarum larvae under laboratory conditions. Early-instar and intermediate-instar larvae were fed on an artificial diet containing 0.1% concentration of insecticide, fungicide or a mixture of both. Larval mortality was assessed daily during the 48 hours after the application of the treatments. Mean mortality values were subjected to analysis of variance and compared by Tukey’s test (p ≤ 0.05). Thiamethoxam caused mortality of 100% of early-instar and 90% of intermediate-instar larvae. In contrast, mortality was significantly lower in the cyproconazole treatment (60% for early-instar and 0% for intermediate-instar larvae) and the control (0% mortality for both treatments). The insecticide/fungicide mixture was equally effective (100% for early-instar and 86.67% for intermediate-instar larvae) to the insecticide only treatment. Differences in mortality between early-instar and intermediate-instar larvae were significant only for the thiamethoxam and cyproconazole treatments. These results indicate that, for the doses used here, thiamethoxam is toxic to both early-instar and intermediate-instar larvae, while cyproconazole is toxic just to early-instar larvae. Moreover, cyproconazole does not increase the toxicity of thiamethoxam. Early-instar larvae are more sensitive to thiamethoxam and cyproconazole than intermediate-instar larvae. We conclude that thiamethoxam + cyproconazole mixture may be effective for managing R. palmarum and associated fungal diseases on coconut palms.

ABSTRACT: Corynespora cassiicola is a cosmopolitan ascomycete widely known as phytopathogen in several crops, and more recently as an emerging pathogen in humans. In this study the genetic variability of 60 isolates of Corynespora cassiicola from different hosts and cities of Amazonas was evaluated, using AFLP molecular markers. Seven genetic groups were identified according to a dendrogram obtained by the Unweighted Pair Group Method using Arithmetical Averages, indicating significant variability among the isolates. Three isolates of different hosts (28, obtained from papaya; 55, obtained from cucumber; and 58, from tomato) remained as single individuals in distinct groups, suggesting marked genetic variation in comparison to the other isolates and possible specificity by the host.

Published: November 2018

Abstract Snake venoms are recognized as a promising source of pharmacologically active substances and are potentially useful for the development of new antimicrobial drugs. This study aimed to investigate the antimicrobial activity of the venom from the rattlesnake Crotalus durissus terrificus against several bacteria. Antibacterial activity was determined by using the plate microdilution method and the activity on the bacterial envelope structure was screened by using the crystal violet assay. The proteins in crude venom were separated by electrophoresis and characterized regarding their proteolytic activity. C. d. terrificus venom exhibited antimicrobial action against gram-positive and gram-negative bacteria. MIC values were defined for Pseudomonas aeruginosa ATCC 27853 (62.5 µg/mL), Staphylococcus aureus ATCC 25923 (125 µg/mL), and Micrococcus luteus ATCC 9341 (≤500 µg/mL). For Salmonella enterica serovar typhimurium ATCC 14028 and Corynebacterium glutamicum ATCC 13032, the decrease in bacterial growth was not detected visually, but was statistically significant. The crystal violet assay demonstrated that the crude venom increased bacterial cell permeability and the secreted protein profile agreed with previous reports. The results suggest that the proteins with lytic activity against bacteria in C. d. terrificus venom deserve further characterization as they may offer reinforcements to the weak therapeutic arsenal used to fight microbial multidrug resistance.

Abstract The increase in zoonotic sporotrichosis cases has become a public health problem in hyperendemic areas for the feline disease. Domestic cats involvement in this transmission and the continuous contact of these animals with soil suggest that the environment may be an essential source and/or reservoir of Sporothrix spp. Thus, the current study aimed to evaluate the presence of Sporothrix spp. in the soil of places where infected cats in Southern Brazil is present. In total, 101 soil samples were collected from the residence of cats with sporotrichosis, from regions around to these residences, and also from public places. These samples were processed using the direct plating technique being incubated at 25 °C for up to 15 days. Additionally, seventeen samples were also submitted to DNA extraction (NORGEN BIOTEK CORP® kit), PCR-specific and Nested-PCR technique. Although the presence of Sporothrix in soil has been undetected, by culture or molecular biology, this study does not reject the role of the environment in the triad of the infectious process (soil-animal-human). Thus, further studies are necessary for expanding the area of coverage, volume, type and method of sampling, and/or detection techniques.

Published: November 2018

RESUMEN El artículo analiza la representación androcéntrica del trabajo en manuales escolares chilenos. Empleando el Modelo de Valoración para Estudios del Discurso, se concluye que aun con mayor inclusión de mujeres en los últimos años, el androcentrismo se expresa en cuatro aspectos centrales: en la consideración del trabajo desde una perspectiva tradicionalmente masculina que devalúa la función reproductiva; en la representación de mujeres en roles tradicionalmente femeninos; en la sobrevaloración de las capacidades físicas y psicológicas de los hombres versus la construcción de mujeres pobres y sufrientes; y en la representación de mujeres integradas al mercado laboral como un fenómeno social reciente que ignora la histórica participación femenina en el mundo del trabajo.

RESUMO Apresentamos um conjunto de indicadores para avaliar a infraestrutura das escolas públicas de ensino fundamental brasileiras. Partimos do pressuposto de que a infraestrutura é um construto complexo, o que justifica a sua avaliação por múltiplas dimensões. Utilizamos os dados do Censo Escolar da Educação Básica e do Sistema de Avaliação da Educação Básica (Saeb), de 2013 e 2015. Os resultados apontam para melhora da infraestrutura no período, mas os padrões de desigualdade conhecidos da literatura se repetem. As escolas rurais, pequenas, municipais, do Norte e Nordeste têm médias mais baixas em todos os indicadores. Também verificamos associação de mesmo sentido dos indicadores de infraestrutura com o nível socioeconômico e o Índice de Desenvolvimento da Educação Básica (Ideb).
Evaluation in distance learning: a case report of the UNASUS/UERJ postgraduate course in elderly health
Authors: Castro Filho José de Almeida , Motta Luciana Branco da
Published: November 2018

Abstract Objective: this analytical case study aimed to evaluate the effectiveness of the UNA-SUS/UERJ Specialization Course in Elderly Health. Method: a mixed-approach evaluation was used, employing the four levels of the Kirkpatrick evaluation model as a reference. Results: the UNA-SUS/UERJ Elderly Health Specialization course presented indicators of success in the three proposed levels of the Kirkpatrick evaluation. The variables identified in the study may be related to a change in the practices of health professionals. Conclusion: the evaluation of distance learning activities in Brazil is still a developing area, a finding that is of increasing importance as large-scale distance learning specialization courses are established and require financial resources whilst lacking a proposed approach to evaluation. It is believed that the present study can contribute to the development of new evaluation projects in distance learning, especially those that impact the elderly population in Primary Health Care, supporting new distance learning projects in the area of aging and correcting the direction of current initiatives.

Abstract Objective: to identify the challenges and technologies of care developed by caregivers of patients with Alzheimer's disease. Method: an exploratory study with a qualitative approach was carried out with nine caregivers of elderly people with Alzheimer's disease from the mutual help group of a university hospital in the south of Brazil. Data collection took place between May and August 2017 through a semi-structured interview. Content analysis was used to analyze the data. Results: two categories emerged from the analysis of the data: the challenges faced by caregivers of elderly people with Alzheimer's Disease and the care technologies developed by caregivers of elderly people with Alzheimer's disease. Conclusion: the study showed that the care strategies elaborated by the caregiver can enhance understanding, reflection and discussion among health professionals, caregivers and family members about quality care for the elderly and minimize the difficulties of care in order to provide greater quality of care for the elderly.

Abstract Objective: to describe the epidemiological profile of elderly persons with leprosy in the state of Alagoas. Method: a descriptive epidemiological study of leprosy cases among the elderly reported to the Disease Notification Information System between 2005 and 2015 was carried out. Results: a total of 896 cases were identified, with a predominance of 60-69 years old (60.5%), who were male (50.4%), had no schooling (34.8%), no source of income (54.1%), multibacillary forms of the disease (67.9%), and a high proportion of grade I (30.3%) and II (11.8%) disability at diagnosis. Hyperendemicity was noted during the survey period, with a mean detection rate of 29.48 cases per 100,000 inhabitants. Conclusion: leprosy is a growing disease among the elderly and early detection should be encouraged in this population to prevent the impairment of active aging.

Resumo Objetivou-se com este estudo desenvolver bebidas alcoólicas fermentadas de melão de diferentes variedades. As polpas extraídas do melão das variedades amarelo e cantaloupe foram diluídas com água (proporção 8:2), sendo corrigido o teor de sólidos solúveis totais para 15 °Brix com sacarose. As misturas tiveram o pH corrigido para 4,5 e foram adicionados 200 mg/L de metabissulfito de sódio e 4 g/L do inócuo. Obtiveram-se, assim, dois mostos para fermentação: F1 (mosto melão amarelo) e F2 (mosto melão cantaloupe). Os mostos foram colocados nos reatores, que foram mantidos a 32 °C durante toda a fermentação. Após a fermentação, foram determinados os parâmetros fermentativos do processo e a caracterização físico-química das bebidas. A amostra F1 apresentou o maior rendimento do processo de fermentação (96,56%), se sobressaindo também, quando comparada a F2, em relação aos parâmetros de produtividade de etanol e biomassa. Os parâmetros físico-químicos apresentaram-se em conformidade com a legislação em sua maioria, com destaque para o teor alcoólico (5,03% e 6,80% v/v), em que a bebida F1 apresentou o maior valor. Conclui-se que as bebidas elaboradas são como alternativas viáveis para diminuir o desperdício de melão, principalmente no pico da safra, e que F1 é a mais indicado para reprodução em escala industrial.
"Apenas aperte o botão...": prática fotográfica amadora em Belo Horizonte
Authors: MENEZES LUCAS MENDES
Published: November 2018

RESUMO Este artigo tem como ponto de partida a questão da influência do aprimoramento tecnológico e comercial da fotografia - assim como de suas veiculações publicitárias -sobre a gênese e o desenvolvimento da prática amadora. Buscou-se mapear como a prática fotográfica foi ofertada e difundida na cidade de Belo Horizonte entre as décadas de 1940 e 1960, através de algumas de suas expressões mais recorrentes. O texto reflete sobre os alcances e os limites da técnica fotográfica, com a atenção voltada ao desenvolvimento de automatismos. Essa discussão tem como base a análise de anúncios de equipamentos e materiais fotográficos em periódicos de grande circulação na capital mineira. Esses reclames, realizados ora por lojas da cidade, ora por companhias fotográficas (por intermédio de seus representantes), apresentam os produtos ofertados, seus recursos técnicos, valores e possibilidades de uso. Por fim, é abordada a criação do Foto Clube de Minas Gerais, primeira agremiação de fotógrafos amadores da capital mineira.
As redes sociotecnológicas e a operação do imaginário instituinte
Authors: Reis Angela Pintor dos
Published: November 2018

Resumo O estudo discute as maneiras pelas quais as redes sociotecnológicas expressam a conjugação de legein e de teukhein, conforme esses termos são concebidos por Castoriadis para designar dimensões do imaginário instituinte. Trata-se de uma reflexão teórica desenvolvida com o objetivo de qualificar as referidas redes como processos do imaginário social. A relevância da discussão reside no tratamento epistemológico inusual das redes sociotecnológicas,abordadas como elementos constituintes dos processos de criação e instituição do social. O procedimento metodológico consistiu na interpretação dos conceitos de legein e de teukhein, aplicados a configurações da comunicação tecnológica mediática, engendrada pelo imaginário de época. O resultado traduziu-se na caracterização das redes sociotecnológicas como expressões do imaginário atinente ao terceiro espírito do capitalismo, segundo perspectiva de Boltanski e Chiapello.
A imagem na arte verbal Maxakali: aspectos de uma poética de pajelança
Authors: Bicalho Charles A. P.
Published: November 2018

Resumo Investigação sobre a imagem na arte verbal dos Maxakali ou Tikmû’ûn, índios que vivem em quatro territórios no estado de Minas Gerais, falam a língua Maxakali, do tronco linguístico Macro-Gê. Com base num dos aspectos centrais da espiritualidade Maxakali – a transformação post mortem do koxuk (palavra, alma) em yãmîy (canto, espírito) – e em manifestações artístico-midiáticas típicas de seus rituais, conectadas ao pano de fundo mitológico, reconhecemos no trato da imagem uma das potências responsáveis pela criação e preservação de suas formas poéticas.

Published: November 2018

Abstract Care for patients with chronic and rare diseases is complex, especially considering the lack of knowledge about the disease, which makes early and precise diagnosis difficult, as well as the need for specific tests, sometimes of high complexity and cost. Added to these factors are difficulties in obtaining adequate treatment when available, in raising patient and family awareness about the disease and treatment compliance. Nephropathic cystinosis is among these diseases. After more than 20 years as a care center for these patients, the authors propose a follow-up protocol, which has been used with improvement in the quality of care and consists of a multidisciplinary approach, including care provided by a physician, nurse, psychologist, nutritionist and social worker. In this paper, each field objectively exposes how to address points that involve the stages of diagnosis and its communication with the patient and their relatives or guardians, covering the particularities of the disease and the treatment, the impact on the lives of patients and families, the approach to psychological and social issues and guidelines on medications and diets. This protocol could be adapted to the follow-up of patients with other rare diseases, including those with renal involvement. This proposal is expected to reach the largest number of professionals involved in the follow-up of these patients, strengthening the bases for the creation of a national protocol, observing the particularities of each case.
