Uma Análise sobre Conhecimento Digital Prévio e Progressão Educacional na Educação a Distância
Get PDFThe objective of this paper is to analyze whether a low computer literacy observed prior the access to a Higher Education course based on Online Distance Learning (ODL) can increase the chances of problems in educational progression. For this, a survey was applied, in 2021, among students of the Computer Engineering and Production courses of the Virtual University of the State of São Paulo (UNIVESP). With the participation of 213 students, it was found, through statistical probability models, that lower computer literacy is not statistically associated with higher failed subject probability. However, it was observed, among students with lower computer literacy, higher chances of thoughts of dropping out of the course, even after controlling for different socioeconomic characteristics of these students.

Higher education.O objetivo do trabalho é analisar se um baixo conhecimento sobre ferramentas digitais observado antes da entrada em um curso do Ensino Superior na modalidade Educação a Distância (EaD) pode aumentar as chances de problemas na progressão educacional. Para isso, aplicou-se um questionário, no ano de 2021, entre alunos dos cursos de Engenharia da Computação e Produção da Universidade Virtual do Estado de São Paulo (UNIVESP). Com a participação de 213 alunos, encontrou-se, através de modelos de probabilidade estatística, que um menor conhecimento das ferramentas digitais não está estatisticamente associado com um maior número de dependências. No entanto foi observado, entre os alunos com menor conhecimento em ferramentas digitais, maiores chances de pensamentos de abandonar o curso, mesmo controlando por diversas características socioeconômicas desses estudantes.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
A violência no estado do Paraná: uma análise espacial das taxas de homicídios e de fatores socioeconômicos
Get PDFConsiderando as altas taxas de homicídios no Estado do Paraná em 2012 o objetivo deste trabalho foi analisar a distribuição espacial no Estado das mesmas nesse ano. Ademais, busca-se verificar a existência de clusters de fatores socioeconômicos que possam apresentar relação com taxas de homicídios no Estado. Nos procedimentos metodológicos foram utilizados análise fatorial e Análise Exploratória de Dados Espaciais (AEDE). O valor do I de Moran foi positivo e significativo porém baixo, indicando que há uma leve dependência espacial positiva no Paraná. As maiores taxas de homicídios foram presenciadas na região metropolitana de Curitiba, Norte do Paraná e fronteira entre o Paraná e Paraguai. Identificou-se a formação de clusters do tipo Alto-Alto entre a variável taxa de homicídio e Índices Municipais (fator1), principalmente nas regiões mais violentas do Estado, indicando que altas taxas de homicídios em uma região estão associadas com altos valores desse fator nos seus vizinhos
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
