Points Of View

Interactions between online users are growing more and more in recent years, due to the latest developments of the web. People share online comments, opinions, and reviews about many topics. Aspect extraction is the automatic process of understanding the topic (the aspect) of such comments, which has obtained huge interest from commercial and academic points of view. For instance, reviews available in webshops (like eBay, Amazon, Aliexpress, etc.) can help the customers in purchasing products and automatic analysis of reviews would be useful, as sometimes it is almost impossible to read all the available ones. In recent years, aspect extraction in the Bangla language has been regarded more and more as a task of growing importance. In the previous literature, a few methods have been introduced to classify Bangla texts according to the aspect they were focused on. This kind of research is limited mainly due to the lack of publicly available datasets for aspect extraction in the Bangla language. We take into account the only two publicly available datasets, recently published, collected for the task of aspect extraction in the Bangla language. Then, we introduce several classification methods based on stacked auto-encoders, as far as we know never exploited in the task of aspect extraction in Bangla, and we achieve better aspect classification performance with respect to the state-of-the-art: the experiments show an average improvement of 0.17 , 0.31 and 0.30 (across the two datasets), respectively in precision, recall and F1-score, reported in the state-of-the-art works that tackled the problem.

Research In Mathematics Education

I found the book Selected Issues in Mathematics Education, jointly published with the National Society for the Study of Education, to be a worthy candidate for one's library. It provides interesting perspectives on a wide range of centrally important topics without getting bogged down in “disease of the week” issues that are parochial in nature. The book is not issue oriented in the sense of presenting various positions for the reader to consider and judge. Many of the chapters convey the authors' views of the state of the art in a particular research area. In some sense, the book could be a companion volume to NCTM's professional reference, Research in Mathematics Education. Still, if one is willing to look beyond what the title suggests, Selected Issues generally makes for good reading, as several authors are willing to share their insights into some rather knotty problems that are likely to be with our profession for some time.

Este trabalho destina-se a responder o que foi produzido no Brasil, nos últimos dez anos, em dissertações de mestrado e teses de doutorado, a respeito do tema Educação Matemática Inclusiva. Para este fim, realizou-se um estudo do estado da arte da Educação Matemática Inclusiva, baseado nos resumos e nas palavras-chave de dissertações e teses, que foram selecionadas por meio do banco de teses da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Capes e busca em páginas do Google Acadêmico. Por meio deste, percebe-se uma tendência para investigações sobre atividades matemáticas digitais e não digitais, que podem auxiliar na aprendizagem de estudantes com deficiências e necessidades educacionais especiais - NEE, atitudes que favorecem essa aprendizagem, compreensão de processos cognitivos envolvidos na aprendizagem matemática, aspectos da formação docente inicial e continuada voltada para a Educação Matemática Inclusiva. Conclui-se que a Educação Matemática Inclusiva é um campo fértil para a realização de novas pesquisas.Palavras-chave: Inclusão. Deficiências. Necessidades Educacionais Especiais.AbstractThe paper attempts to answer: what was produced in Brazil in master’s degree and doctoral theses, over last ten years, regarding the theme inclusion in Mathematics Education? To this end, we carried out a study on the state of the art of Inclusive Mathematics Education, based on the abstracts and keywords of dissertations and theses, consulting the database from Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Capes and Academic Google webpages. Through this, it is realized a tendency on investigations about digital and non-digital mathematical activities to assist in the students with disabilities’ learning and special educational needs (NEE) and attitudes that promote such learning. Research also seeks to understand the cognitive processes involved in mathematics learning, aspects regarding the initial and continuous Teaching formation focused on Inclusive Mathematics Education . It is concouded that Inclusive mathematics Education is a fertile field for new research.Keywords: Inclusion. Disabilities. Special Educational Needs.

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.
