O Dia Mundial do Professor celebra-se anualmente no dia 5 de outubro, para celebrar a aprovação, em 5 de outubro de 1966, da Recomendação da UNESCO/OIT sobre o Estatuto dos Professores. Em reconhecimento de todos aqueles que dedicam o seu dia-a-dia a ensinar, partilhamos a dinâmica das aulas em algumas cadeiras dos cursos de Antropologia no Departamento de Ciências da Vida, desenhadas por C. Rodrigues. Professora Sandra Xavier Aula: Métodos de Investigação (Mestrado em Antropolog..
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Perspective chapter: the Lean approach in Waste management. A case study
This work presents a manufacturing case study focused on reducing waste in a
corrugated paperboard packaging company located in Italy. Corrugated paperboard is
the primary material used in transporting, distributing, and storing many products,
particularly food productions. The project started in September 2020 with the aim
of identifying the causes of some waste along the production process and the consequent planning of actions to reduce them. This project was implemented following the logic of lean manufacturing through the use of the PDCA (Plan-Do-Check-Act) methodology. The quality control tools for continuous improvement of the manufacturing process are used. The results achieved by the plant are significant in terms of economic and environmental sustainability. From an economic point of view,
the measures implemented have allowed the plant to achieve, in the period between
September 2020 and March 2021, a decrease from 10% to 9% of the percentage of
the waste with a cost reduction approximately of € 17,000 for each of the first three
months of 2021. From an environmental point of view, waste reduction is one of the
objectives underlying the sustainability strategy adopted by the company, which has
long been committed to the responsible management of its production processes to
reduce its environmental impact
Variations on the Author
“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
We 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
Dispelling the Myths Behind First-author Citation Counts
We 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
We 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
