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
Impact Assessment Regime for Sustainable Agricultural Innovation Processes: the Triple Helix System of Innovation for Sustainability (THIS)
Full text linkAufgrund einer größeren finanziellen Unsicherheit im Zusammenhang mit ökologischen Risiken sind nachhaltigkeitsorientierte Innovationen in einem Marktumfeld weniger wahrscheinlich. Übergeordnetes Ziel dieser Studie ist es, Innovationsprozesse in der Landwirtschaft zu analysieren und ihre Fähigkeit zur Integration marktgetriebener und ökosystemorientierter Aktivitäten zu bewerten. Dadurch soll ein Domainansatz in der Landwirtschaft überwunden werden. Entwickelt wurde dafür ein Rahmen für die Analyse und das Management von nachhaltigkeitsorientierten Innovationsprozessen: das Triple Helix System der Innovation für Nachhaltigkeit (THIS). Es soll die Interaktion zwischen landwirtschaftlicher Praxis, Forschung und Politik bei transformativen Veränderungsprozessen unterstützen. Der Rahmen wurde basierend auf einer Fallstudienanalyse in drei Interaktionsebenen eingeteilt, die für die Aushandlung von Nachhaltigkeitszielen über den Markt und das Ökosystem relevant sind: 1) die technologische, 2) die organisatorische und 3) die Governance-Ebene. Grundlage für die Übersetzung von Nachhaltigkeitszielen auf die lokale Ebene sind die übergreifenden Ziele der Vereinten Nationen für nachhaltige Entwicklung (SDGs). Auf jeder Ebene ergeben sich spezifische Forschungsfragen: in der Vorplanung (Front End), in der Einbindung von Managementfunktionen, und in der Berücksichtigung von Indikatoren für Nachhaltigkeit in politischen Gesetzentwicklungsprozessen. Die Analyse, die sich aus der Anwendung von THIS ergibt, trägt zur Debatte über tragfähige Formen des Innovationsmanagements für zielorientierte Innovationen bei. THIS dient somit als Rahmen, um Innovationsprozesse zu beschleunigen und die zusätzlichen Unsicherheiten bei den im Agrarsektor entwickelten Innovationen frühzeitig zu berücksichtigen. Schließlich zeigt diese Studie, wie sich die Anforderungen eines iterativen Managements in Organisationsstrukturen für institutionelle Unterstützung widerspiegeln können.Due to greater financial uncertainty in connection with ecological risks, sustainability-oriented innovations are less likely to be successfully adopted in a market environment. The overall objective of this study is to analyse innovation processes in agriculture, and to assess their ability to integrate market-driven as well as ecosystem-oriented activities across different levels of relationship interaction. To overcome a domain approach in agriculture, a framework for the analysis and management of sustainability-oriented innovation processes in agriculture was developed: the Triple Helix System of Innovation for Sustainability (THIS). It is set to enhance the diffusion and utilisation of new knowledge generated by interaction between agricultural practice, research and policy. The framework looks at three levels of relationship interaction relevant to the negotiation of market versus ecosystem, including 1) technological, 2) organisational, and 3) governance aspects. The negotiation of sustainability goals is conducted by translating the overarching global United Nations Sustainable Development Goals (SDGs) to the substantive focus of innovation in each case. Each level of relationship interaction reveals specific research questions, addressing for example the consideration of sustainability impacts at the beginning of an innovation process (the front end), management functions required to organise and steer an innovation process, and the potential for integrating indicators for sustainability in policy regulation and governance. The study contributes to the debate on viable forms of innovation management for goal-oriented innovation processes. The application of THIS achieves to address additional uncertainty posed particularly by environmental aspects characteristic to the agricultural sector. Finally, this study shows how the requirements of iterative management can be reflected in organisational structures for institutional support
