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
EXPLORATIONS IN WORKFLOW SCHEDULING FOR DYNAMIC CLOUD COMPUTING SYSTEMS
No full text本文探讨云计算中使用的动态环境，解决了一些与在这种环境下工作流调度相关的主要问题。由于动态环境中的工作流调度是基于不同的标准完成的，因此不同的目标会造成多种不同的结果。针对我们的目标，本文专注于两个主要问题，文中的第三章和第四章致力于对这两个问题进行研究，并在每章节末尾对提出的启发式解决方法进行验证，实验结果表明我们能够获得预期目标。 第三章描述的问题是关于把工作流调度到一个异构资源的集合中，我们利用随机模型产生任务的执行时间、以及任务间的传输时间；利用这样的随机模型，确定性调度启发式可以偶尔表现良好。通过对一个众所周知的确定性启发式进行扩展，我们提出了一种新的随机调度方法。通过大量的仿真实...This thesis explores dynamic environments that cloud computing faces and addresses some of the main issues associated with workflow scheduling in these environments. Workflow scheduling in dynamic environments is done based on different criteria, this results in various objectives. In this thesis we focused on two main problems which related to our objectives, the two chapters (chapter 3 and chapt...学位：工学硕士院系专业：信息科学与技术学院_计算机科学与技术学号：2302014115464
L'université et le développement : analyse de deux institutions universitaires d'Afrique noire à la lumière du concept de développement : l'Université nationale du Rwanda et l'Université de Dar-es-Salaam en Tanzanie
No full textLes universités du monde entier vivent un malaise profond. Dans les pays du Tiers-Monde, les problèmes à son égard, s'accumulent et les solutions restent fragiles. En Afrique, l'institution universitaire ne parvient pas à surmonter les traumatismes de la colonisation. Dans l'ère du développement, la réalité éducationnelle et la fonction universitaire paraissent engluées dans des mécanismes très complexes. Comment cela est-il possible? Existe-t-il une corrélation entre tous ces éléments? Afin d'apporter des éléments de discussion à ces interrogations, il est fait ici une étude, non exhaustive certes, des traits fondamentaux qui exerceraient une influence considérable sur la fonction universitaire. En effet, nous pensons que l'institution universitaire est étroitement liée à l'idée que l'on se fait du développement de la société en général. Corollairement, nous émettons l'hypothèse qu'une théorie de développement, qu'une société choisit de privilégier, influe nécessairement sur les finalités, les objectifs de l'université et les attitudes que l'on développe à son endroit. En guise d'illustration de cette assertion, nous tentons dans ce travail, une analyse de deux universités d'Afrique Noire, au Rwanda et en Tanzanie, au niveau des programmes, de la recherche et des principes qui guident l'accessibilité à ce niveau d'enseignement. Pour ce faire, nous nous proposons d'adopter une démarche à double volet. D'une part, nous allons analyser une intense documentation: ouvrages généraux, documents officiels et inédits au sujet des deux universités. Dans un deuxième temps, nous allons compléter cette approche par des interviews auprès de cinq personnalités qui ont eu à s'impliquer dans le développement des deux universités en question. Notre but final est d'essayer de dégager une explication cohérente des relations entre l'Université et les conceptions de développement en Afrique, au Rwanda et en Tanzanie.Québec Université Laval, Bibliothèque 201
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
