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
Men´s use of parental leaves and their involvement in child care in europe
Get PDF[Resumen] En la última década los poderes públicos han fomentado el uso de los permisos parentales por parte de los hombres como un nuevo mecanismo para fomentar la igualdad de género y la no discriminación por razón de maternidad. En este trabajo se analiza a partir de la encuesta europea de condiciones de trabajo de 2005, recurriendo a la submuestra correspondiente a padres de hijos menores de 8 años, si efectivamente el uso de los permisos parentales por los hombres se traduce en una mayor implicación en el cuidado de sus hijos y en el trabajo doméstico. A partir de un análisis de regresión logística en el que se controla por distintas características del trabajo, la situación familiar y el nivel educativo, los resultados confirman que los hombres que han hecho uso del permiso parental en el año previo a la encuesta están más frecuentemente implicados en el cuidado diario de los niños y en la realización del trabajo doméstico que quienes no han hecho uso de esta posibilidad. El uso por los hombres del permiso parental se evidencia así como un mecanismo que promueve su socialización en las tareas de cuidado no remunerado.[Abstract] During the last decade, policy developments in the field of parental leave have tended to promote actively men´s use of this kind of leave as a way for promoting a greater gender equality. Using the European working conditions survey 2005, in particular the subsample of fathers with children less than 8 years old, this article analyses the research question if men´s use of parental leave is related with a greater involvement in childcare and housework. Based on a binomial logistic regression, controlling for different aspects of work conditions, family situation and educational level, results show a positive relationship between men´s use of parental leave in the year previous to the survey and daily childcare and housework involvement. Men´s use of parental leave seems then to be an effective mechanism of men´s socialization in care activities
Geographic job mobility and parenthood decisions
Get PDF"In diesem Beitrag wird der Frage nachgegangen, inwieweit hohe berufsbedingte räumliche Mobilität negative Folgen auf die Familienentwicklung hat. Im ersten Teil des Aufsatzes wird getrennt nach Geschlecht analysiert, ob Mobilität Kinderlosigkeit fördert, eine Verschiebung des Geburtenkalenders verursacht und ob sie eine Reduktion der Familiengröße zur Folge hat. Darüber hinaus wird in dem zweiten Teil analysiert, welchen Einfluss bestimmte Arbeitsbedingungen sowie die Ressourcen, die Familien zur Verfügung stehen, um Familie und Beruf zu vereinbaren, auf die Entscheidungen bezüglich Elternschaft ausüben. Die Analyse stützt sich auf eine repräsentative Umfrage in sechs europäischen Ländern (Deutschland, Frankreich, Spanien, Polen, Schweiz und Belgien) mit Personen im Alter zwischen 25 und 54 Jahren. Die Daten wurden in 2007 erhoben. Mobile Erwerbstätige wurden überproportional erhoben, um eine ausreichende Fallzahl zu gewährleisten. Die Ergebnisse zeigen, dass die Auswirkung der Mobilität auf die Familienentwicklung von Bedeutung ist, wobei sich Mobilität von Frauen stärker auswirkt. Darüber hinaus ist von Bedeutung, wann im Lebenslauf Mobilität und Elternschaft stattfinden und wie lange die Phase der mobilen Arbeit andauert. Flexible Arbeitszeiten oder die Möglichkeit, einen Teil der Arbeit zu Hause zu leisten, haben keinen eindeutigen Einfluss auf die Entscheidungen zur Elternschaft von mobilen Erwerbstätigen, wohl aber die Unterstützung durch den Arbeitgeber. Unterstützung seitens des Partners scheint die Entscheidung mobiler Frauen für Kinder nicht zu fördern." (Autorenreferat)"The aim of this paper is to analyse, differentiated by gender, the effects that high geographical job mobility has on parenthood decisions. In particular, in a first part we will examine whether job mobility fosters childlessness and/ or postponement of childbearing and if mobility implies a lower family size. In a second part we will analyse how the specific working conditions of mobile people and their resources for balancing working and private lives affect childlessness and postponement of parenthood. The analysis will be based on a representative survey of people aged 25 to 54, performed in six European countries (Germany, France, Spain, Poland, Switzerland and Belgium) in 2007, oversampling mobile people in order to get enough cases to analyse. Results show that the impact of high job mobility on the timing and quantum of parenthood is important, both for men and women, but stronger for the latter. Besides gender, the strength of the impact depends on the duration of job mobility and when it takes place in the lifecycle. Resources for promoting a better balance of working and private lives such as flexitime and teleworking have no clear impact on parenthood decisions, but having a supportive employer facilitates family development of mobile employees. A greater involvement of men in unpaid work does not seem to facilitate fertility decisions of mobile women." (author's abstract
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
