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
Studies on informal research collaborations and knowledge transfer : empirical evidence from the micro-level
No full textGroßangelegte Studien unter innovierenden Organisationen haben gezeigt, dass insbesondere in wissenschaftsbasierten Industrien informelle F&E-Vereinbarungen eine wesentliche Rolle für den Wissenserwerb und die Prozesse von Wissensgeneration in Organisationen (z.B. Firmen) spielen.Während zahlreiche Studien die Konsequenzen formaler F&E-Vereinbarungen für die Wissensgeneration und den Wissenstransfer von Organisationen im Innovationsprozess untersuchen, mangelt es auf der Mikroebene an empirischer Evidenz über die Auswirkungen von informellen F&E-Vereinbarungen und den daraus resultierenden Konsequenzen für die Wissensdynamik von innovierenden Einrichtungen. Dies ist hauptsächlich der Tatsache geschuldet, dass informelle F&E-Vereinbarungen schwierig zu definieren und messen sind. Die vorliegende Doktorarbeit besteht aus vier empirischen Teilen, die alle das Thema informelle F&E-Partnerschaften beinhalten und empirisch die Auswirkungen informeller F&E-Kollaborationen auf die Wissens- und Kooperationsdynamik innovierender Organisationen auf der Mikroebene untersuchen.Large scale surveys among innovating organizations have shown that especially in science based industries informal R&D agreements are regarded to play a crucial role for the knowledge acquisition and knowledge generation processes of innovating organizations (e.g. firms).
While there are various studies that examine the consequences of formal R&D agreements for the knowledge generation and transfer activities of innovating organizations, the micro level empirical evidence on informal R&D agreements and the resulting consequences for the knowledge dynamics of innovating organizations is rare. This is mostly due to the fact that informal R&D agreements are difficult to define and measure. This thesis consists of four empirical parts that all touch upon the issue of informal R&D partnerships and provides more micro level evidence on both, the formation motives and consequences of informal R&D collaborations

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
Against the one-way-street: Analyzing knowledge transfer from industry to science
Full text linkThis study aims at analyzing the differences in the factors that influence the probability of knowledge transfer within industry and from industry to science in the biotechnology sector. In order to model these knowledge flows a citation analysis on the basis of patent data was conducted and a weighted bivariate probit model was estimated on the citation probability of industry and science on the basis of a combined sample of citing and cited patent pairs and an equal number of control patent pairs. The empirical results suggest that there are considerable differences in the citation probability. Cultural closeness for instance has a positive effect on the citation probability from industry to industry while the citation probability of scientific institutions is not affected by cultural distance. --Technology transfer,patent citation analysis,biotechnology industry
