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
Beyond economic growth: the role of innovation in shaping social impact
Full text linkThe ultimate goal of economics is to understand and improve social welfare. Nevertheless, the dominant discussion in economics is still centered on production, consumption, and monetary outcomes. Therefore, economic growth has been one of the main goals of politics for the last few decades. As a prominent driver of technological progress, regional and national competitiveness, and ultimately, economic growth, technological innovation is often at the core of these considerations. However, growth and innovation are also increasingly associated with adverse side effects. Moreover, the focus shifted from pure economic towards more inclusive approaches, also considering social effects. Indeed, there is comprehensive evidence for an urgent call to think beyond economic growth from all parts of society. The role of innovation may consequently also be reconsidered to improve people’s quality of life instead of solely fueling pure economic growth. This dissertation addresses several research gaps on the social consequences of innovation. It first explores the influence of universities on a micro and an institutional level. This work further examines the social impact of radical innovations by disentangling the complex relationship between radical innovations and objective well-being. Finally, a new approach to measure the concept of social innovation and thus enable more empirical work in this field is created. The findings show that the potential of universities regarding their social impact is largely unused. Moreover, the social consequences of innovation are often overlooked. They need to be known and properly addressed. This urges policymakers, stakeholders, and researchers to adopt a more nuanced view regarding the effects of innovations and actors of innovation systems. Social considerations need to be included and complement the focus on technological advancement prospectively
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
The entrepreneurial process of the entrepreneurs in Germany and the role of experiential learning in this process
Full text linkDiese Dissertation schlägt vor, Unternehmertum durch die Theorie des Erfahrungslernens nach Kolb (2015) zu fördern. Unternehmertum wird erreicht, wenn es dem Unternehmer gelingt, eine Gelegenheit zu erkennen. Unternehmerische Selbstwirksamkeit, innovatives Verhalten und die Wahrnehmung von Chancen sind die Säulen des konzeptionellen Modells dieser Forschung. Die Schätzungen dieses Modells stützten sich auf Primärdaten, die von Unternehmern in Deutschland erhoben wurden (N=309). Für die Datenanalyse und den Test des hypothetischen Modells wird in dieser Studie das Strukturgleichungsmodell (SEM) verwendet. Die Ergebnisse zeigen, dass die unternehmerische Selbstwirksamkeit einen direkten, positiven Effekt auf das Erkennen von Chancen bei deutschen Unternehmern hat. Die Ergebnisse deuten darauf hin, dass innovatives Verhalten die direkte Beziehung zwischen unternehmerischer Selbstwirksamkeit und Chancenwahrnehmung vollständige Mediation vermittelt. Der Einsatz von innovativem Verhalten zur hancenerkennung führt zu einer innovativen Gelegenheit und damit zu einem Mehrwert für die Wirtschaft. Um diesen unternehmerischen Prozess zu unterstützen, schlägt diese Studie für jedes Konstrukt des konzeptionellen Modells einen erfahrungsbasierten Lernstil vor. Die aktuelle Studie erklärt empirisch, warum manche Menschen in Deutschland eine Chance erkennen können, andere aber nicht. Auf diese Weise erklärt sie, warum Unternehmer in Deutschland eine höhere Wertschöpfung erbringen als in den Nachbarländern der Europäischen Union. Des Weiteren leistet sie einen Beitrag zur Unternehmer-Ausbildung, indem sie die Theorie des Erfahrungslernens in einen unternehmerischen Prozess einführt, durch den ein Unternehmer lernt, eine Gelegenheit zu erkennen. In diesem Zusammenhang wird versucht zu beantworten, wie Unternehmer lernen können, eine Chance wahrzunehmen
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
