    O trabalho tem como proposta analisar a incidência de clickbait no jornalismo online português e brasileiro. Faz parte de uma atividade realizada em conjunto por pesquisadores brasileiros e portugueses, em que cada grupo efetuou a verificação em 18 veículos de informação geral do seu país com abrangência nacional, com produção própria e atualizada frequentemente, tanto nas páginas web, assim como no Facebook. Este artigo traz os resultados encontrados na amostra brasileira que apontam um alto índice de clickbait ao se verificar os dados gerais, com 54,4% da amostra com ocorrência desta prática. Ao mesmo tempo, os valores se reduzem ao olharmos os 32 indicadores individualmente, em que apenas tr�\xAAs tiveram índices superiores a 10%.The paper aims to analyze the incidence of clickbait in Portuguese and Brazilian online journalism. It is part of an activity carried out jointly by Brazilian and Portuguese researchers, in which each group carried out the verification in the Web and Facebook pages of 18 general information vehicles of such countries, each having national coverage, as well as its own production and frequent updates. This article presents the results found in the Brazilian sample that shows a high clickbait index, of 54.4%, when crosschecking the general data. On the other hand, the values are reduced when we look at the 32 indicators individually, in which only three had rates above 10%

    A investigação que aqui se apresenta partiu da proposta de analisar a incidência de clickbait no ciberjornalismo português e brasileiro. Faz parte de um projeto desenvolvido em conjunto por investigadores brasileiros e portugueses, em que cada grupo efetuou a verificação em 18 cibermeios de informação geral do seu país com abrangência nacional e com produção própria e atualizada frequentemente, tanto nas páginas Web como no Facebook. Neste artigo apresentamos os resultados encontrados nos 270 títulos/conteúdos que constituíram a amostra portuguesa, que apontam para um índice de clickbait de 39,6%. Analisando individualmente os 32 indicadores, verificamos que nenhum chega aos 10%, destacando-se como valor mais alto a "Informação empolada", presente em 8,5% da amostra.The paper aims to analyze the incidence of clickbait in Portuguese and Brazilian online journalism.

    The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

    The digital elevation models (DEMs) are being widely used. Its applications can be related to prevention, planning and monitoring of activities in space, whether urban or rural. One of its main applications is linked to agriculture being a tool for strategic decision making to improve agricultural practices or reducing impacts on the environment. Measuring the accuracy of a DEM is a job that requires going to the field and check sampled points for the best models. This study aims to evaluate and compare the DEM with MDE generated from the contours of the IBGE. We performed trip to the field to collect sample points randomly in the study area. We applied the square root of the mean square error (RMSE) of the elevation of the extent of agreement Kappa. The altimetric variation between MDE made a small difference, and SRTM DEM presented the highest values in both the maximum altitude as the minimum. Regarding spurious depressions observed that the MDE SRTM showed a total of 10 times the value identified in the MDE curves IBGE. The drainage network extracted from DEMs showed a slight difference in their extensions, the MDE curves showed greater extent than the SRTM DEM. The RMSE of the two MDEs were low but still standard in accordance with a scale of 1:50,000.Pages: 4716-472
