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
Le travail scolaire lycéen hors de la classe : une analyse de pratiques au croisement des cultures scolaires et juvéniles
No full textHigh school students' out-of-class work is a subject with little research documentation, and existing studies primarily focus on work "for the institution", what the student is supposed to do, rather than work "for oneself", what the student actually does. In this research, we propose to explore this work "for oneself" by first characterizing high school students' practices related to out-of-class schoolwork, and secondly, by questioning the possible connections between youth cultures and school cultures within the context of these practices, as the cultural aspect appears to be essential in this work. Our methodological approach is inspired by ethnography, and our field is multi-sited, involving "everyday conversations" with high school students, online digital trace research, and interviews. Our results show that high school students can use internet forums to ask academic questions, and that these questions and the responses received serve as resources for others. Additionally, students may also turn to YouTube videos as supplements to their academic courses. Moreover, while Google is used as a "search engine" to access internet forums and YouTube videos, it can also be used as an "answer engine". Finally, the reliance on peers high school students appears to be a substantial component of this out-of-class schoolwork. An ecosystem emerges between the school's cultural space and the youth's cultural space, and we propose a schematic representation of it. It is within this ecosystem that practices specific to each culture can interconnect and hybridize.Le travail scolaire lycéen hors de la classe est un sujet peu documenté par la recherche et les travaux existants sont surtout orientés sur le travail "pour l'institution", ce qu'est censé faire l'élève et jamais sur le travail "pour soi", ce que fait l'élève réellement. Nous proposons dans cette recherche d'explorer ce travail "pour soi" d'une part, en caractérisant les pratiques lycéennes relatives au travail scolaire hors de la classe et d'autre part, en questionnant les articulations possibles entre cultures juvéniles et cultures scolaires dans le cadre de ces pratiques car la question culturelle nous apparaît comme essentielle dans ce travail. Notre approche méthodologique est inspirée de l'ethnographie et notre terrain est multi-situé entre "conversations courantes" avec des lycéens, recherches de traces numériques en ligne et entretiens. Nos résultats montrent que les lycéens peuvent mobiliser les forums Internet pour poser des questions scolaires et que ces questions et les réponses obtenues constituent des ressources pour d'autres. Mais les lycéens peuvent également recourir aux vidéos YouTube comme compléments de leurs cours académiques. De plus, si Google est utilisé comme "moteur de recherche" pour accéder aux forums Internet et aux vidéos YouTube, il peut être également utilisé comme "moteur de réponse". Enfin, le recours aux pairs lycéens apparaît comme un élément substantiel de ce travail scolaire lycéen hors de la classe. Un écosystème entre espace culturel scolaire et espace culturel juvénile se dessine alors et nous en proposons une schématisation. C'est au sein de cet écosystème que les pratiques propres à chaque culture peuvent s'articuler et s'hybrider
La pédagogie inversée : recherche sur la pratique de la classe inversée
No full textThis paper presents a study on the inverted teaching method of physics and chemistry courses at the high school level. This study shows that students achieving high grades in the traditional classroom setting are globally less successful in the flipped classroom setting, while the lower-achieving students in the traditional classroom demonstrate a better performance in the flipped classroom. This inversion of student performance is surely explained by the adaptation the high-achieving students have made to the traditional system, and the tendency of the lower-achieving students to work harder in the flipped classroom setting.Cette rubrique présente une étude sur la pédagogie inversée au lycée en cours de sciences physiques et chimiques. Cette étude montre que les élèves de bon niveau en sciences dans le système de classe traditionnelle sont globalement moins performants en classe inversée alors que les élèves de niveau plus faible dans la classe traditionnelle sont plus performants dans le système de classe inversée. Cette inversion de la performance est à rapprocher avec une adaptation des élèves de bon niveau au système traditionnel et une tendance à travailler plus pour les élèves de moins bon niveau lorsqu’ils sont dans un système de classe inversée.Faillet Vincent.

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
High school students' out-of-class work : an analysis of practices at the intersection of academic and youth cultures

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
