Published: August 2018

Resumo: O objetivo com o estudo foi verificar a atratividade nos retornos dos investimentos de empresas brasileiras do agronegócio com o uso do modelo Capital Asset Pricing Model (CAPM). Para isso, realizou-se pesquisa descritiva, análise documental e utilizou-se abordagem quantitativa. A amostra é composta por ações de 13 empresas do agronegócio brasileiro negociadas na BM&FBovespa e o período de análise compreende os anos de 2010 a 2014. Os achados apontaram que o CAPM identifica maior atratividade para as empresas do agronegócio brasileiro quando comparado com a média do mercado dado pelo IBovespa. Contudo, o CAPM foi eficiente para dimensionar os retornos esperados apenas nos anos 2010, 2011 e 2014, sendo que, em 2012 e 2013, a atratividade apontada pelo CAPM foi significativamente menor do que o retorno real, fato que pode ser entendido por meio de aspectos econômicos, pois o setor do agronegócio cresceu nesse período em oposição ao baixo desempenho geral do mercado. Por fim, salienta-se que o retorno real médio foi constatado superior para as empresas do agronegócio brasileiro em relação ao retorno do mercado em geral. Por vezes, apresentaram retornos reais maiores do que o esperado e, assim, foram consideradas atrativas para investimentos pela maximização dos ganhos no mercado acionário brasileiro.Palavras-chave: Atratividade dos investimentos.

Return of investments of brazilian agribusiness companies Abstract: The aim of the study is to assess the attractiveness of the investment returns of Brazilian agribusiness companies using the Capital Asset Pricing Model (CAPM). For this, was achieved descriptive research, document analysis and quantitative approach. The sample is composed of 13 Brazilian agribusiness companies listed on the BM&FBovespa and the analysis period comprises the years between 2010 to 2014. The findings indicated that the CAPM identifies more attractiveness for companies in the agribusiness compared to the market average given by IBovespa. However, the CAPM was efficient to scale the expected returns only in the years 2010, 2011 and 2014, occurring in 2012 and 2013, that the attractiveness appointed by CAPM was significantly lower than the actual return, which can be understood through economic aspects, because the agribusiness sector grown in this period in opposition to the low overall market performance. Finally, it should be noted that the average real return was found to be higher for the brazilian agribusiness companies in relation to the market return in general. At times, they had higher-than-expected real returns and thus were considered attractive for investments by maximizing earnings in the Brazilian stock market.Keywords: Attraction of investments.

Resumo: Com o intuito de fortalecer a sua competitividade, micro e pequenas empresas têm adotado como estratégia participarem de redes interorganizacionais em razão de benefícios associados. Porém, do ponto de vista empírico, observa-se que empresas saem ou trocam de redes. No estudo teve-se como objetivo identificar os motivos que levam uma empresa a trocar de rede de cooperação. A consecução deste trabalho ocorreu por intermédio de uma pesquisa qualitativa de natureza exploratória, sendo o instrumento de coleta uma entrevista semiestruturada com o proprietário de uma empresa do setor supermercadista que decidiu trocar de rede de cooperação, e três empresários que saíram de redes de diferentes ramos de atividade e os presidentes dessas três redes. Os resultados demonstraram que, apesar dos muitos benefícios oriundos da participação em redes, se algumas das perspectivas individuais que as empresas tinham ao entrar na rede não forem correspondidas, ocorre a insatisfação, fazendo com que as empresas busquem novas oportunidades. Com os resultados do estudo, espera-se ter contribuído para ajudar os empresários e gestores na decisão de entrar e/ou sair de uma rede de cooperação.Palavras-chave: Redes interorganizacionais. Troca de rede. Problemas.

Zen Studio Meditation for Kids by P. Bonita & B. Silverman

Bonita, P., & B. Silverman. Zen Studio Meditation for Kids. Edoki Academy, 2016. Vers 1.15. Apple App Store, https://itunes.apple.com/us/app/zen-studio-meditation-for-kids/id1051358262?mt=8
Suggested age range: 4+ Cost: Free with in app purchases (complete version $3.99 USD)
Edoki Academy has effectively created an app that allows children to appreciate music and art as relaxation aids. Their Zen Studio Meditation for Kids is a painting app that allows children to virtually finger paint by filling in a grid of triangles with colours as music notes simultaneously play. The free version of the app offers two blank canvases and two canvases with tutorials that they can follow. The app is designed well and is intuitive enough that is does not need the clutter of menus or instructional detours. The only instances where guidance is visible are when new spaces on the grid are exposed to guide users to the next colour, or when the congratulatory confetti explodes on the screen to signify that a tutorial is completed. It is important to note that once a tutorial is completed the music continues to play and children can continue painting over the triangles as they please without the pressure to move on to a new tutorial. There is no feedback or time limit given for the tutorials because the point is to relax and enjoy the process. What makes the app unique is the layering of music that happens when the background meditation music blends with the notes that play each time a triangle is filled in with colour. This allows children to relax to the background music and be encouraged to create their own melodies as they are painting.
The graphic design elements are simple and clean and there are no words that prompt you to select a canvas or a tutorial. Instead of words, the app uses animation and magnification to show that a selection has been made. It is very clear when a choice has been made because it appears in colour and the universal “play” triangle symbol appears, leading the user to click there to begin the painting.
A handbook for parents and teachers is also included in the app. This additional document provides information on mindfulness and the intentions behind Edoki Academy’s Zen Studio Meditation for Kids. It also offers some learning exercises and questions that parents or teachers can supplement with the app. This app is recommended for creative children who enjoy music and painting, or those who would benefit from learning new ways to reduce stress or anxiety and practice mindfulness.

A Day with Yayah by N. Campbell
Authors: Thorne Lydia 
Published: August 2018

Campbell, Nicola. A Day with Yayah. Illustrated by Julie Flett. Tradewind Books, 2017.
A Day with Yayah is a story that portrays a close relationship between a grandmother and her grandchildren. In A Day with Yayah, an Indigenous family makes a trip to British Columbia’s Nicola Valley to collect wild herbs and mushrooms. Along the way, the grandmother, Yayah, takes the opportunity to teach her grandchildren their language and to pass down her knowledge of edible plants and herbs. Yayah and her family are Nle?képmx (Interior Salish peoples), who are often referred to as People of the Creeks. Campbell draws on her own background for this story, having grown up in the same valley where the story is set.
Illustrator and award winning Cree-Métis artist, Julie Flett, provides stunning, brightly coloured full-page illustrations. Flett’s detailed drawings complement the narrative, and her folk-style characters, with their jubilant expressions and bright clothing, emphasize the importance of knowledge transfer from one generation to the next.
Over the years, the language of the Interior Salisham people has become endangered and Campbell introduces her readers to twelve words in the Salish language. These words appear within the dialogue of the story several times, giving children the chance to identify and connect with these words. The glossary at the end of the book is a very helpful addition and aids readers with pronouncing and translating the terms that are used throughout the story. The phrasing of the sentences and the inclusion of Salish words makes this a more appropriate read-aloud to younger readers, but it would also be suitable for independent reading for students in elementary school. This book is highly recommended for both school and public libraries.

Where Oliver Fits by C. Atkinson
Authors: Kung Janice 
Published: August 2018

Atkinson, Cale. Where Oliver Fits. Toronto, Tundra Books, 2017.
Oliver is a unique little puzzle piece with a cute round head smattered with blue and orange. He wants to be part of a bigger picture and goes on a journey to find where he fits. As he finds different puzzles, he discovers that the other puzzle pieces are not like him at all. Some puzzle pieces complain that he does not have enough of the right colour to fit properly. Others say that he is not the right shape. Determined to find his place in the world, he decides that he needed to be more like others in order to be accepted.
He uses creative strategies to change his shape and colour, however, after continuing to be rejected, he becomes desperate enough to create a disguise to finally fit into a puzzle. Although he finally finds his fit, Oliver begins to question whether or not it was right to pretend he was someone else and learns that it is better to be himself.
This is a wonderful story of imagination. Children learn through the eyes of Oliver that it is better to be one’s true self rather than changing to fit in. The illustrations are bright, colourful, and capture all the conflicting emotions that Oliver goes through. Designed for children ages 3-7, this book provides a good moral lesson in a fun and creative way.

Tooth loss and associated factors in adolescents – impact of extractions for orthodontic reason.
Authors: Colussi Paulo Roberto Grafitti , Hugo Fernando Neves , Muniz Francisco Wilker Mustafa Gomes , Rösing Cassiano Kuchenbecker 
Published: August 2018

Aim: To investigate tooth loss and its determinants in adolescents, considering the effect of extractions due to orthodontics reasons. Methods: This cross-sectional study was performed in students from public and private schools aged 15-19 years old from Passo Fundo, Brazil. The proportional randomly chosen sample included 736 adolescents. Clinical examinations and interviews were performed. Associations between prevalence of tooth loss and exposure variables studied were analysed by Poisson Regression with uni- and multivariate robust variance in two models. One model comprised students who had experienced tooth loss without orthodontic reasons and the other with all of the subjects presenting tooth loss. Results: Prevalence of tooth loss was 21.1% (mean of 0.42). Higher chances for tooth loss were found in the following features: non-whites (PR=1.72; CI95%:1.15-2.60), poorly schooling mothers (PR=2.2; CI95%:0.96-5.02), from public schools (PR=4.16; CI95%:0.98-17.59), smokers (PR=1.91; CI95%:1.15-3.17). Conclusion: Demographic, socioeconomic and behavioural conditions were strongly associated with tooth loss. These associations were more evident when extractions for orthodontic reasons were not included in the analytical models.
O espaço da troca: a comunicação sem palavras na trilogia Xenogenesis de Octavia Butler
Authors: Cardoso André Cabral de Almeida 
Published: August 2018

Nos romances de ficção científica que formam a trilogia Xenogenesis, de Octavia Butler, a criação de híbridos de humanos com alienígenas dá origem a uma nova subjetividade utópica baseada na fluidez e no apagamento das fronteiras entre os indivíduos, cujas sensações e emoções circulam numa espécie de comunicação sem palavras que elimina a mediação da linguagem verbal. Um ideal de comunicação semelhante pode ser encontrado na cultura sentimental que se consolidou na França e na Grã-Bretanha em meados do século XVIII. Esse ideal encontra sua expressão paradigmática na pequena comunidade de Clarens descrita em Julie, ou la nouvelle Héloïse, romance sentimental de Jean-Jacques Rousseau. Ao comparar esses dois textos que pertencem a gêneros radicalmente diferentes e escritos em contextos tão distintos, o objetivo deste artigo é examinar como se constitui o resgate de um modelo de comunicação sentimental numa narrativa de ficção científica americana escrita no final do século XX, e a sua relevância nesse novo contexto. Eu também vou discutir as possibilidades utópicas desse modelo de comunicação e o que ele pode revelar a respeito da imaginação utópica contemporânea, assim como estabelecer algumas conexões entre a nossa cultura atual e a tradição sentimental do século XVIII.
Uma leitura de The Machine Stops, a distopia tecnológica de E. M. Forster
Authors: Moraes Helvio 
Published: August 2018

Apresentamos uma leitura do conto The Machine Stops, de E.M.Forster, publicado em 1909. Na descrição de um mundo governado pela máquina, Forster expõe sua crítica a certas tendências do século que começava: o isolamento do indivíduo, o esfacelamento das relações humanas, o crescente desenvolvimento tecnológico e industrial, a crença desmedida no progresso, o distanciamento do homem em relação à natureza, a repressão da faculdade instintiva, o enrijecimento das convenções sociais e a consciência de classe. Em nossa análise, privilegiamos a relação entre os gêneros literários da utopia e da ficção científica, a partir de estudiosos que retomam e, por vezes, fazem uma revisão crítica dos estudos pioneiros de Darko Suvin, publicados durante a década de setenta. O conto de Forster também nos possibilita investigar a crise de certos paradigmas da tradição utópica – como a tensão entre liberdade individual e o controle do Estado -, por ser um dos textos fundadores da literatura distópica que, ao longo de todo o século XX, terá uma enorme difusão. Nesse sentido, nosso estudo também busca compreender a complexa relação entre as noções de utopia e distopia, a partir da distinção conceitual elaborada por Berriel.
Ficção científica no Brasil: O Choque das Raças ou O Presidente Negro, de Monteiro Lobato
Authors: Tin Emerson 
Published: August 2018

O objetivo deste artigo é o de analisar em que medida o romance O presidente negro ou O choque das raças (1926), de Monteiro Lobato (1882-1948), insere-se, por um lado, na produção do escritor e, por outro, na então incipiente produção de ficção científica no Brasil. Pretende-se ressaltar os aspectos ficcionais e literários do romance, em geral pouco analisados ou, até mesmo, negligenciados diante de interpretações especulativas a respeito de supostas filiações ideológicas de seu autor.
História das viagens à lua: Um percurso e uma apresentação de Man in the Moone de Francis Godwin
Authors: Caixeta Bruna Pereira 
Published: August 2018

A história das viagens à Lua inicia-se com Plutarco, com Sobre a face visível da órbita da Lua. No entanto, deste pioneiro, os posteriores escritores aproveitarão apenas a ida à Lua, visto que sua viagem é inteiramente regida pelo mote da religião grega. Somente serão inseridos nas viagens à Lua os elementos que hoje mais as enriquece: a sátira, encontrada em Icaromenipo e Narrativas Verdadeiras de Samósata, a crítica social, em The first Man in the Moonde H.G Wells, a visão distanciada do mundo e a consideração científica e astronômica, de Kepler emSomniuim e John Wilkins, em The Discovery of a World in the Moone. Francis Godwin, bispo anglicano autor deThe Man in the Moone (1638) herdará a tradição das viagens à Lua luciânicas, e na sua narrativa procurará oferecer um projeto político para o reinado de Jaime I, ficando no impasse entre a saudação dos tempos augustos do governo de Elisabete I e a reformulação do modelo de governo monárquico.
As primeiras fichas do modernista Mário de Andrade
Authors: Figueiredo Tatiana Longo 
Published: August 2018

Acompanhando as citações e menções do “Prefácio interessantíssimo” de Pauliceia desvairada, primeiro livro do modernista Mário de Andrade, o artigo busca verificar as matrizes na biblioteca do escritor e documentos no Fichário analítico que respaldaram sua criação. Sem contar com fichas de leitura seria bastante difícil a empreitada de escrever o “Prefácio Interessantíssimo”, esforço de síntese ao explicar a nova poética e ao demonstrar o contato com as vanguardas europeias. Possivelmente, esse momento inaugura o Fichário analítico, manuscrito formado em mais de duas décadas, com 9.634 documentos, elencados por assunto em dez divisões e que materializa a necessidade de reunir e ordenar coerentemente fontes de pesquisa.
ESTUDO PALEOBIOLÓGICO DE RESTOS HUMANOS PROVENIENTES DO SÍTIO BAIXA DAS FLORES, LIMOEIRO DE ANADIA, ALAGOAS, BRASIL

Published: August 2018

Os estudos paleobiológicos são uma importante fonte de informações acerca das condições de saúde e das dinâmicas bioculturais das populações do passado. No caso específico da tradição arqueológica Aratu, pouco se conhece a respeito da biologia de sua população, o que em parte se deve ao fato de que os remanescentes ósseos nem sempre estão presentes nas urnas funerárias escavadas ou, quando estão, as condições de preservação impedem estudos dessa natureza. No caso do Sítio Baixa das Flores, apesar de possuir uma pequena amostra osteológica, esses estudos tornam-se relevantes pelo fato de proporcionarem uma primeira observação biológica das populações humanas inseridas na tão vasta tradição arqueológica Aratu no Nordeste brasileiro.

AS ITACOATIARAS DO INGÁ: Gravuras pintadas?
Authors: Nascimento Ana Luísa Meneses Lage do , Lima Tânia Andrade 
Published: August 2018

A Pedra Lavrada do Ingá, com suas características singulares e grande concentração de gravuras, pode ser interpretada como local destinado a práticas ritualísticas pelos grupos que dela se apropriaram, atribuindo-lhe significados que parecem relacioná-la ao domínio do sagrado (NASCIMENTO, 2015). Ao estudá-la, observamos em algumas gravuras a presença de uma pigmentação avermelhada, fato que nos levou a investigar se as itacoatiaras do Ingá teriam sido também pintadas. Para tanto, os pigmentos foram avaliados em microscópio, além de terem sido feitas análises por espectroscopia de fluorescência de raios X. O presente artigo discute a metodologia, as técnicas e apresenta os resultados alcançados. THE ITACOATIARAS OF INGÁ: Painted Carvings?ABSTRACTThe Pedra Lavrada do Ingá, with its singular characteristics and large concentration of carvings, can be interpreted as a site for ritualistic practices by the groups that appropriated it, giving it meanings that seem to relate it to the sacred domain(NASCIMENTO, 2015). During our study, we observed the presence of a reddish pigment within some carvings, a fact that leads us to investigate if the Ingá itacoatiaras could have been also painted. In order to address this, pigments were scrutinized under the microscope, whereas x-ray fluorescence spectroscopic analyses were also performed. This study addresses the methods, the techniques and the achieved results.Keywords: Pedra do Ingá, engraved painted, methods of analyzis.
