O objetivo da pesquisa é descrever o cenário da imigração germânica no século XIX, tratando também, de trilhar o caminho da educação por meio de educadores e das comunidades na Colônia de Santa Leopoldina, criada em 1857, na Província do Espírito Santo, considerando 50 anos a partir do início da imigração (1857-1907). A pesquisa histórica ancorou-se em consultas a documentos oficiais do Império, documentos e relatórios oficiais dos Presidentes da Província do Espírito Santo, jornais de circulação da época, fotografias, mapas geográficos, mapas estatísticos, livros didáticos antigos e livros de autores que abordaram o processo imigratório do Espírito Santo. O diálogo com Marc Bloch ajudou a entender essa multiplicidade de documentos, na complexa relação entre o passado e o presente da educação do Espírito Santo. O trabalho apresenta uma trajetória do imigrante germânico vindo da Europa até a ex-colônia e como a administração da província tratou a imigração e a educação. O ensino primário iniciou-se a partir de iniciativas públicas e particulares. Foram identificados as primeiras escolas e os nomes de muitos professores que atuaram no período estudado. Os livros utilizados nas escolas das comunidades teuto-brasileiras eram oriundos da Alemanha e posteriormente foram produzidos no sul do Brasil. Entre os livros escritos em alemão encontrados destacam-se o livro texto de alfabetização „Lese – Schule I für Deutsche Kinder in Brasilien‟, editado na Alemanha no final do século XIX, de autoria do diretor de uma escola particular em Santa Leopoldina, Albert Richard Dietze, e o primeiro volume do livro de matemática „Rechenbuch für Deutsch-Brasilianische Volksschulen‟, de Ferdinand Hackbart, Konrad Glaus e Hermann Lange. Foi feita uma análise sob os aspectos físicos e formais, o processo de ensino e os conteúdos do livro de matemática. A análise evidenciou que a proposta de ensino apoia-se no “cálculo mental” e o escrito, com a repetição dos conteúdos, envolvendo o treino intensivo. Os conceitos de matemática são apresentados partindo de problemas com situações concretas do aluno para a aquisição de competências necessárias para inserir o aluno em sua comunidade. Levando-se em conta que o livro foi editado em 1906, conclui-se que se trata de uma obra relevante com uma proposta de ensino que se manteve presente nos livros didáticos de matemática até os dias atuais.

The rise in ischemic heart disease(IHD) mortality occurring mostly during the first half of the 20th century is usually associated with economic development and its consequences for people's lifestyles. On the basis of historical evidence, it is postulated that a previous IHD epidemic cycle may have occurred in England and Wales towards the turn of the nineteenth century. The implications of this on causal theories and current etiological research on atherosclerosis are discussed.

Over 60,500 dengue cases were reported in the state of Espírito Santo (ES), Brazil, between 1995 and 1998. The study's purpose was to identify whether Aedes albopictus was transmitting the dengue virus during an epidemic in the locality of Vila Bethânia (Viana County),Vitória, ES. From April 3 to 9, 1998, blood and serum samples were collected daily for virus isolation and serological testing. Four autochthonous cases were confirmed through DEN 1 virus isolation and two autochthonous cases through MAC ELISA testing. Of 37 Ae. aegypti and 200 Ae. albopictus adult mosquitoes collected and inoculated, DEN1 virus was isolated only from a pool of two Ae. aegypti female mosquitoes. The study results suggest that Ae. albopictus still cannot be considered an inter-human vector in dengue epidemics in Brazil.

The large increase of renewable energy sources and Distributed Generation (DG) of electricity gives place to the Virtual Power Producer (VPP) concept. VPPs may turn electricity generation by renewable sources valuable in electricity markets. Information availability and adequate decision-support tools are crucial for achieving VPPs’ goals. This involves information concerning associated producers and market operation. This paper presents ViProd, a simulation tool that allows simulating VPPs operation, focusing mainly in the information requirements for adequate decision making.

Deep Ocean Species. The little that is known mostly comes from collected specimens. L.A. Rocha et al. Letter "Specimen collection: An essential tool" (23 May, 344: 814) brilliantly discuss the importance of specimen collection and present the evolution of collecting since the mid-19th century until our present strict codes and conducts. However, it is also important to emphasize the fact that the vast majority of deep ocean macro-organisms are only known to us because of collection and this is a strong argument that should be present in our actions as scientists. If the deep is considered the least known of Earth’s habitats (1% or so according to recent estimates) then what awesome collection of yet to discover species are still there to be properly described? As the authors point citing (1), something around 86% of species remain unknown. Voucher specimens are fundamental for the reasons pointed out and perhaps the vast depths of the World’s oceans are the best example of that importance. The resumed report of 2010 Census of Marine Life (2) showed that among the millions of specimens collected in both familiar and seldom-explored waters, the Census found more than 6,000 potentially new species and completed formal descriptions of more than 1,200 of them. It also found that a number of rare species are in fact common. Voucher specimens are essential and, again agreeing with L.A. Rocha et al. Letter (see above), the modern approach for collecting will not be a cause for extinctions but instead a valuable tool for knowledge, description and even, as seen above, a way to find out that supposed rare species may not be that rare and even prove to reach abundant populations.

Predators and Tourism Increase Intolerance? A. Treves and J. Bruskotter Perspective in Ecology "Tolerance for Predatory Wildlife" (2 May, 344: 476) suggest that intolerance for predators do not fit into the conventional view of perceived threats for livelihoods but instead by complex social factors. Although the above perspective focuses in jaguars, wolves, lions and bears, the same reasoning is perfectly applied to other economical contexts and different human-wildlife interactions. Nature tourism is a growing industry attracting a significant number of people to exotic places to see wildlife and, of course, many predators are on the main "menu". [...].

The Desertas Islands (Madeira, Portugal) are the sole home of one of the largest and rarest wolf spiderspecies, Hogna ingens (Blackwall 1857) (Araneae, Lycosidae). Despite its size, it inhabits a single valleyin the North of the Deserta Grande Island, Vale da Castanheira, currently invaded by the herb Phalarisaquatica. This invasive species competes with the native flora and was subject to several eradicationexperiments, namely through fire and chemicals. The objectives of this work were to: (1) estimate thecurrent distribution and abundance of H. ingens and respective trends; (2) evaluate the impact of theinvasive plant and eradication methods on the spider population; (3) suggest future measures for therecovery of the species; and (4) evaluate its conservation status according to the IUCN criteria. The current distribution of H. ingens covers 23 ha, a recent reduction from its original 83 ha, correspond-ing to the entire Vale da Castanheira. A total of 4447 and 4086 adults and 71,832 and 24,635 juvenileswere estimated to live in the valley during 2011 and 2012, respectively. We found a significant negativeimpact of P. aquatica cover on the presence and abundance of H. ingens and that chemical treatmentspecifically directed towards the invasive plant species may be the only way to effectively recover thespider's habitat. We suggest (1) regular monitoring; (2) extend chemical treatments; (3) ex-situ conserva-tion with future reintroduction of adults. Based on the current area of occupancy (AOO) of H. ingens and itsrecent decline in both AOO and number of individuals, it was recently classified as Critically Endangeredby IUCN and we suggest its urgent inclusion in the Habitats Directive species lists.

In the business world, employees can contribute with information, ideas, concerns, opinions and proposals to their managers in respect of: (1) the way work could be performed, (2) what should / should not be done in the workplace, (3) how a particular decision can be implemented, and (4) how an organizational policy should be formed and executed (Rego, 2013). However, due to a diverse set of factors, employees often choose to remain silent in the workplace. One of these factors is psychological safety, which describes employees’ perceptions of the consequences of taking interpersonal risks in the workplace (Edmondson, 2014). The following paper is essentially a literature review and its aim is to, firstly, make a brief approach to factors reported in the literature that may affect employee voice and silence, followed up by an explanation of the types of silence that can be engaged by employees. Besides that, the authors will also make an approach to physical and psychological safety. Lastly, it will be reported some links, mentioned in the literature, between employee silence and psychological safety.

The '10/90 gap' was first highlighted by the Global Forum for Health Research. It refers to the finding that 90% of worldwide medical research expenditure is targeted at problems affecting only 10% of the world's population. Applying research results from the rich world to the problems of the poor may be a tempting, potentially easy and convenient solution for this gap. This paper had the objective of presenting arguments that such an approach runs the risk of exporting failure. Health interventions that are shown to be effective in the specific context of a Western industrialized setting will not necessarily work in the developing world.

O processamento de amostras citológicas em meio líquido e a coloração de May-Grünwald Giemsa (MGG) fazem parte da rotina em anatomia patológica. Na origem desta investigação esteve a possibilidade do uso desta coloração em amostras processadas em ThinPrep (TP). Estudou-se a fase compreendida entre o processamento de amostras em TP e a coloração com MGG – pós-processamento. O objetivo do estudo consistiu em avaliar diferentes métodos de pós-processamento em amostras de secreções brônquicas processadas pela metodologia TP e coradas com MGG. Utilizaram-se 32 amostras de secreções brônquicas, processadas em TP. De cada amostra obtiveram-se três lâminas, nas quais se aplicaram três métodos de pós-processamento: secagem ao ar; imersão em solução salina de tampão Tris; imersão em etanol a 96%. Realizou-se a coloração de MGG e as lâminas foram avaliadas por três avaliadores independentes, relativamente à constituição da amostra e qualidade da coloração. Este último parâmetro resultou da soma da pontuação obtida para os detalhes nuclear e citoplasmático (escala de 0 a 4 valores). Aplicaram-se os testes estatísticos One-Way ANOVA (p=0,05) e de Tukey. Para a qualidade de coloração, os métodos imersão em solução tampão, imersão em etanol a 96% e secagem ao ar obtiveram a pontuação média de 2,39 (s=1,309), 2,15 (s=1,248) e 1,22 (s=1,250), respetivamente. Verificou-se que existia diferença estatisticamente significativa entre o método secagem ao ar e os métodos imersão em solução tampão e em etanol a 96% (p=,000). O pós-processamento por secagem ao ar demonstrou qualidade da coloração não aceitável, ou seja pontuação média inferior a 2 valores. Pelo contrário, os pós-processamentos por imersão em solução tampão e em etanol a 96% apresentaram qualidade de coloração aceitável, podendo ser utilizados na rotina laboratorial para coloração com MGG de amostras processadas em TP.
