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
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
Repérage de quelques difficultés des élevés du secondaire scientifique dans l’enseignement des sciences physiques
Full text linkLa didactique des sciences constitue un champ de recherche majeur visant à améliorer la qualité de l’enseignement et à réduire les obstacles à l’apprentissage. En particulier, les sciences physiques occupent une place centrale dans le système éducatif, tant en raison de leur importance scientifique que de leur rôle dans le développement des compétences analytiques et expérimentales. Cette recherche explore les difficultés rencontrées par les élèves marocains du secondaire scientifique dans l’apprentissage des sciences physiques et leurs répercussions sur la transition vers l’enseignement supérieur. Bien que la physique soit une science fondamentale, elle reste l’une des disciplines les plus redoutées, contribuant largement aux échecs observés dans les filières scientifiques. L’étude repose sur une enquête par questionnaire à choix multiples administrée à un échantillon de 300 élèves issus de lycées publics et privés répartis dans différentes régions du Maroc. Les résultats montrent que si la majorité des élèves connaissent globalement les objectifs de l’enseignement des sciences physiques, près des deux tiers ignorent les modalités d’évaluation. Les difficultés d’apprentissage sont principalement attribuées aux méthodes pédagogiques utilisées et au faible volume horaire. Par ailleurs, les élèves considèrent la discipline comme centrée sur les examens plutôt que sur ses applications réelles, même s’ils reconnaissent généralement son utilité. Plus de la moitié des participants estiment néanmoins que certaines parties du programme préparent à la poursuite d’études universitaires. Concernant les enseignants, les élèves expriment une préférence pour les professeurs masculins mais reconnaissent que, dans l’ensemble, les enseignants déploient des efforts pour faciliter la compréhension des notions. Face à ces constats, plusieurs pistes sont proposées : réviser et alléger le programme pour le rendre plus adapté à la transition secondaire–supérieur, renforcer les séances pratiques en laboratoire, intégrer les technologies de l’information et de la communication (TIC), et favoriser une pédagogie plus interactive. La conclusion souligne deux priorités : développer la formation continue des enseignants et accroître le volume horaire consacré aux sciences physiques. Ce travail contribue à enrichir la réflexion sur la didactique des sciences au Maroc et appelle à une meilleure articulation entre enseignement secondaire et supérieur.
The didactics of science constitute a major field of research aimed at improving the quality of teaching and reducing barriers to learning. In particular, physics occupies a central place in the educational system, both because of its scientific importance and its role in the development of analytical and experimental skills. This study explores the difficulties faced by Moroccan secondary school students in learning physics and their impact on the transition to higher education. Although physics is a fundamental science, it remains one of the most feared disciplines, contributing significantly to the failures observed in scientific streams. The research is based on a multiple-choice questionnaire administered to a sample of 300 students from public and private high schools across different regions of Morocco. The findings show that while most students generally understand the objectives of physics education, nearly two-thirds are unaware of the assessment methods. Learning difficulties are mainly attributed to the teaching approaches used and the limited number of instructional hours. Furthermore, students perceive the discipline as exam-oriented rather than focused on real-life applications, even though they generally acknowledge its usefulness. More than half of the participants nonetheless believe that certain parts of the curriculum prepare them for university studies. Regarding teachers, students express a preference for male instructors but acknowledge that, overall, teachers make efforts to facilitate the understanding of concepts. In light of these observations, several recommendations are proposed: revising and streamlining the curriculum to make it more suitable for the secondary-to-higher education transition, strengthening laboratory practice sessions, integrating information and communication technologies (ICT), and fostering more interactive pedagogy. The conclusion highlights two priorities: developing continuous teacher training and increasing the number of instructional hours devoted to physics. This work contributes to enriching the reflection on science didactics in Morocco and calls for better alignment between secondary and higher education

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
