Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Education pour la paix et le développement: stratégies pour son intégration dans le système éducatif malien
Full text linkCet article présente le processus d’intégration de l’éducation à la paix dans le système éducatif malien. Elle fait un état des lieux tout en procédant à une analyse des stratégies assortie de propositions. Le Mali connait, de plus en plus, des crises multiformes, conduisant à des conflits, et donc à des situations de paupérisation annihilant l’efficacité des politiques de développement. L’éducation à la paix et le développement revêt une importance indéniable, car elle permet aux différentes couches sociales d’apprendre à vivre ensemble tout en étant nanties de moyens de prévention et de règlement des situations conflictuelles. La recherche se veut une contribution à la compréhension de l’expérience malienne d’implantation de l’éducation à la paix et au développement dans le système éducatif. Les objectifs sont: -Analyser le processus de mise en œuvre de l’éducation à la paix et au développement au Mali, dans le cadre de son intégration dans le système éducatif malien; - Proposer des stratégies pour une intégration durable de l’éducation à la paix et au développement. La recherche documentaire et empirique ainsi que des entretiens ont permis de recueillir des informations et des données. Les résultats révèlent une faille éducative dans le processus d’introduction de la culture de la paix et le développement. Le constat fait ressortir aussi une approche parcellaire et disparate à travers une introduction de portions de l’enseignement de la culture de la paix dans certaines disciplines scolaires. Ce qui justifie les propositions de stratégies appropriées, en investissant avec efficience dans l’élaboration des curricula d’enseignement au travers d’une discipline spécifique dédiée à l’enseignement de compétences liées à la paix selon les ordres et types d’enseignement pour une intégration structurante et durable.
This paper focuses on the process of integrating peace education into the Malian education system. It takes stock of the situation while carrying out an analysis of strategies accompanied by proposals. Mali is increasingly experiencing multifaceted crises, leading to conflicts, and therefore to situations of impoverishment that destroy the effectiveness of development policies. Education for peace and development is of undeniable importance because it allows different social strata to learn to live together while being provided with the means to prevent and resolve conflict situations. The research is intended to contribute to understanding the Malian experience of implementing peace and development education in the education system. The objectives are: - Analyze the process of implementing education for peace and development in Mali, as part of its integration into the Malian education system; - Propose strategies for a sustainable integration of education for peace and development. Documentary and empirical research, as well as interviews, gathered information and data. The results reveal an educational flaw in the process of introducing the culture of peace and development. The observation also highlights a fragmented and disparate approach through the introduction of portions of the teaching of the culture of peace in certain school subjects. This justifies the proposals for appropriate strategies by investing efficiently in the development of teaching curricula through a specific discipline dedicated towards the teaching of skills. These skills are related to peace according to the levels and types of teaching for structural and sustainable integration
Null controllability of a nonlinear population dynamics problem
Full text linkWe establish a null controllability result for a nonlinear population dynamics model. In our model, the birth term is nonlocal and describes the recruitment process in newborn individuals population. Using a derivation of Leray-Schauder fixed point theorem and Carleman inequality for the adjoint system, we show that for all given initial density, there exists an internal control acting on a small open set of the domain and leading the population to extinction
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
