A new genus, a new species and taxonomic notes in Oxycoleini Martins & Galileo, 2003 (Coleoptera, Cerambycidae, Cerambycinae)

Oxylopsebus Clarke, 2008 is considered as a junior synonym of Oxycoleus Lacordaire, 1868. Equescollum is proposed as a new genus for E. birai sp. nov. from Costa Rica, which is described and illustrated

O DILEMA DA MIMESIS EM ARTHUR DANTO

Este artigo tem por objetivo abordar a crítica do pensador estadunidense Arthur Danto à concepção da arte como mimesis, observando que à apreensão do tema haveremos de abordar o conceito tanto sob o aspecto histórico quanto essencialista de sua filosofia. Nesse sentido, abordaremos a mimesis sob a crítica de sua condição de narrativa mestra e, a seguir, do dilema que tal concepção faz emergir no âmbito teorético quando lhe é atribuído o caráter de natureza da arte

A importância do estágio supervisionado para a formação docente: um relato de experiência

O Estágio Supervisionado pode ser utilizado como uma ferramenta essencial para criar laços estreitos com a futura profissão pretendida. Neste trabalho, objetivou-se relatar as experiências adquiridas durante o estágio em uma escola de Ensino Profissionalizante localizada na cidade de Fortaleza. As turmas de Hospedagem I e Segurança I foram os grupos de estudantes escolhidos para o desenvolvimento das atividades do estágio. No decorrer da experiência, houve o cumprimento de diversas etapas como a observação da escola, da regência do professor efetivo, a prática da regência, a aplicação de aulas complementares e de dois minicursos. Ao final da prática, pôde-se concluir que o estágio além de ser uma mera disciplina da grade curricular, também incorpora múltiplos conhecimentos da formação profissional, desenvolvendo habilidades e competências para a condução de uma sala de aula

On Eryphus Perty, 1832 (Dichophyiini), Eriphus Audinet-Serville, 1834 (Trachyderini, Trachyderina), and Eryphus Klug, 1829, with description of a new genus, and corrections on publication dates (Coleoptera, Cerambycidae)

The validity of two forgotten names, Eryphus Klug, 1829 and E. rubricollis Klug, 1829, is discussed. The former is considered a nomen oblitum and synonymized with Eriphus Audinet-Serville, 1834, a nomen protectum; the latter is revalidated and Eriphus purpuratus Chevrolat, 1862 is considered a junior synonym of Eriphus rubricollis (Klug, 1829). A lectotype is designated to Eryphus rubricollis Klug, 1829. The date of the work where Eriphus Audinet-Serville, 1834 was described is corrected. A new genus is described in Dichophyiini Gistel, 1848 to include the species currently allocated in Eryphus sensu Napp & Martins (2002). The dates of publication of genera and species described by Fairmaire & Germain (Révision des Coléoptères du Chili (suite)) are corrected

A Novel Feature Selection Method for Uncertain Features: An Application to the Prediction of Pro-/Anti- Longevity Genes

Understanding the ageing process is a very challenging problem for biologists. To help in this task, there has been a growing use of classification methods (from machine learning) to learn models that predict whether a gene influences the process of ageing or promotes longevity. One type of predictive feature often used for learning such classification models is Protein-Protein Interaction (PPI) features. One important property of PPI features is their uncertainty, i.e., a given feature (PPI annotation) is often associated with a confidence score, which is usually ignored by conventional classification methods. Hence, we propose the Lazy Feature Selection for Uncertain Features (LFSUF) method, which is tailored for coping with the uncertainty in PPI confidence scores. In addition, following the lazy learning paradigm, LFSUF selects features for each instance to be classified, making the feature selection process more flexible. We show that our LFSUF method achieves better predictive accuracy when compared to other feature selection methods that either do not explicitly take PPI confidence scores into account or deal with uncertainty globally rather than using a per-instance approach. Also, we interpret the results of the classification process using the features selected by LFSUF, showing that the number of selected features is significantly reduced, assisting the interpretability of the results. The datasets used in the experiments and the program code of the LFSUF method are freely available on the web at http://github.com/pablonsilva/FSforUncertainFeatureSpaces

Sensory characteristics of wood from naturally fallen Amazonian trees for manufacture of products in Extractive Reserves

In view of the national and international demand for wood for industrial use, solutions are being created to combat and reduce deforestation. One such solution is to use wood from naturally fallen trees. However, there has been limited evaluation of the technological potential of this material. This study therefore aimed to assess the general characteristics of wood from naturally fallen tree species in the Auatí-Paraná Extractive Reserve (RESEX), for potential use in product development. The characteristics analyzed were color, texture, grain, heartwood, sapwood and density. The species of naturally fallen trees were assessed using online databases, specialized literature and the xylotheque at the Wood Anatomy and Identification Laboratory of the National Institute of Amazonian Research (LAIM/INPA). This study and its results confirm the great quantity and quality of wood from naturally fallen trees with technological potential for the development of products, based on the classification of the sensory characteristics of the woods
