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
From Letter to Twitter: A Systematic Review of Communication Media in Negotiation
No full textWith the advent of modern communication media over the last decades, such as email, video conferencing, or instant messaging, a plethora of research has emerged that analyzes the association between communication media and negotiation processes and outcomes. In this paper, the author systematically reviews theoretical vantage points on communication media and negotiation and summarizes empirical findings from the last six decades. Specifically, the author focuses on three different strategic communication theories and four social psychological theoretical perspectives that found traction in negotiation research. Subsequently, empirical evidence on communication media and negotiation is presented, derived from an extensive literature search of relevant peer-reviewed articles. The author analyzes effects of communication media on the negotiation process (descriptive process parameters, economic reference points, negotiation behavior/tactics, individual perceptual and affective process variables) as well as economic (agreement, individual profit, joint profit, dispersion of profits) and socio-emotional (satisfaction, trust, socio-emotional evaluation of the self and the opponent) outcomes. The discussion takes stock of the current state of research and persisting research gaps, before focusing on some recent developments, and proposing future research avenues
Merkmale, Messung, Einflussfaktoren und Auswirkungen
Get PDFMarketingaktivitäten werden in Business-to-Business Unternehmen typischerweise nicht nur in der Marketingabteilung, sondern von mehreren Akteuren entlang der Wertschöpfungskette durchgeführt. Die vorliegende Arbeit thematisiert fünf Aspekte dieses Phänomens mithilfe eines Mixed-Methods-Forschungsdesigns. Es geht dabei zunächst darum zu verstehen, was genau Marketingaktivitäten in Business-to-Business Unternehmen sind und wie diese strukturell verankert sind. Der zweite Fokus liegt auf der Messung des Grads der Dispersion von Marketingaktivitäten. Hierzu wurde ein Messinstrument entwickelt, das neben der Messung des aggregierten Dispersionsgrads pro Unternehmen große Unterschiede der zwölf untersuchten Marketingaktivitätsbündel aufzeigen konnte. Einflussfaktoren und Auswirkungen des Grads der Dispersion von Marketingaktivitäten stellen den dritten Forschungskomplex dar. Auf Basis der Ergebnisse konnten sieben interne bzw. externe Einflussfaktoren sowie sieben Outcome-Dimensionen nach Effizienz und Effektivität identifiziert werden. Die Rolle der Informalität ist das vierte Themengebiet der Arbeit. Der fünfte Themenblock der Arbeit ist auf das Zusammenspiel zwischen der Dispersion von Marketingaktivitäten und Informationsmanagement gerichtet, das eine der Outcome-Dimensionen ist. Hierbei ging es insbesondere darum abteilungsübergreifende Informationsakquise sowie -distribution genauer zu untersuchen. Diese fünf Forschungsthemen waren in drei empirischen Sequenzen des Mixed-Methods-Designs eingebettet: die erste Sequenz stellt eine branchenübergreifende Interviewstudie dar, die zweite Sequenz ist eine qualitative Fallstudie und die dritte Studie ist eine rein quantitative Fragebogenerhebung.Marketing activities in business-to-business firms are typically conducted along the entire value chain and are not just embedded in one department. The dissertation focuses on five key research elements regarding the phenomenon of the dispersion of marketing activities with a mixed-methods-research design: First of all, the relevant marketing activities in a business-to-business context and their structural constellations are analyzed. Secondly, a measurement tool of the degree of dispersion was developed. Not only the aggregated degree of dispersion, but also the more detailed level of the degree of dispersion of twelve marketing activity bundles can be analyzed with the measurement tool. Antecedents and outcome dimensions of the degree of dispersion are identified as the topic of the third research focus. Seven internal/external antecedents and seven effectiveness/efficiency outcome-dimensions are revealed. The role of the informal degree of dispersion represents the fourth research topic. The fifth and final topic sheds light on the relationship between the dispersion of marketing activities and information management (cross-departmental acquisition and distribution of information). These five research topics were embedded in a mixed-methods-research design containing three empirical sequences: a cross-industry interview study, a qualitative case study and a cross-industry survey study
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
Communication Media and Negotiation: A Review
No full textWith the advent of modern communication media over the last decades, such as email, video conferencing, or instant messaging, a plethora of research has emerged that analyzes the association between communication media and negotiation processes and outcomes. This chapter reviews theoretical vantage points on communication media and negotiation and summarizes empirical findings from the last five decades. Specifically, the author focuses on media richness theory and the task/media fit hypothesis, grounding in communication, and media synchronicity theory as communication theoretical foundations that found traction in negotiation research. These theoretical vantage points are supplemented by a review of specific theoretical psychological aspects of communication media, the barrier effect and psychological distance theory. In the second part of the chapter, empirical evidence on communication media and negotiation is presented, derived from an extensive literature search of relevant peer-reviewed articles. The emphasis in this review of the empirical literature is on the communication medium as an independent variable. In other words, the author analyzes effects of communication media on the negotiation process (descriptive process parameters, economic reference points, negotiation behavior/tactics, individual psychological variables, assessment of the opponent) as well as economic (agreement, individual profit, joint profit, equality of agreement) and socio-emotional (satisfaction, future interaction, trust) outcomes. A succeeding subsection is devoted to communication medium choice in negotiation, a topic much less researched. The conclusion sums up the findings and sketches out some avenues for future research
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
