    The 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

    “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

    We 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

    Die Kleinstädte in ländlichen, strukturschwachen Regionen stehen vor komplexen Herausforderungen, die durch demografische Verschiebungen, wirtschaftliche Schwierigkeiten und soziale Umwälzungen geprägt sind. Die Rückwanderung, als vorherrschende Form der Zuwanderung in diesen Gebieten, (vgl. Meister et al. 2020) hat in den letzten Jahren zunehmend an Bedeutung gewonnen. Zudem hat sich der Umgang mit dem Thema, im Speziellen in der Rückwanderungsförderung, in den letzten Jahren stark weiterentwickelt. (vgl. G3 (1) 2023) Rückwanderung dient nicht mehr nur der Stabilisierung von Einwohnerzahlen, sondern birgt auch große Potentiale für die lokale und regionale Entwicklung. Diese Studie untersucht die Rolle der Rückkehrer:innen für die Entwicklung von Kleinstädten und fragt, welchen Beitrag sie leisten können. Die Forschungsarbeit basiert auf einer theoretischen Annäherung, in der Wirkungsfelder der Rückwanderung (Wirtschaft, Kultur und Soziales, Bildung und Wissenstransfer sowie Vernetzung) diskutiert und in qualitativen Interviews mit Rückkehrer:innen und Vertreter:innen verschiedener Kleinstädte überprüft werden. Die Ergebnisse zeigen, dass die Kleinstädte trotz ähnlicher Voraussetzungen in der Rückwanderungsförderung an sehr unterschiedlichen Punkten stehen. Dabei werden die Wirkungsfelder der Rückwanderung in Bezug auf den Mehrwert für die Städte sehr unterschiedlich wahrgenommen. Hier stehen vorwiegend die kurzfristigen Effekte von Rückwanderung im Blick von Maßnahmen zur Förderung und Unterstützung. Diese lösen jedoch nicht die grundlegenden, häufig strukturellen Probleme der Kleinstädte. Das Potential der Rückwanderung zeigt sich stattdessen vor allem in langfristigen Effekten. Rückkehrer:innen präsentieren sich als engagierte Personen, die auch nach ihrem Ankommen einen Beitrag zur Stadtentwicklung leisten können. Sie tragen zudem zu einem positiven entwicklungsoffenen Umfeld bei. Dieses Potential wird von den Kleinstädten zwar ebenso wahrgenommen, jedoch ist es noch kein Teil von Maßnahmen zur Förderung und Unterstützung. Die Herausforderung besteht nicht nur darin, Projekte von Engagierten zu unterstützen. Gerade wegen der immer stärkeren Einbindung in Familie und Beruf sind daran angepasste zielgruppengerechte Begegnungs- und Gemeinschaftsräume Rückkehrer:innen, aber auch Gebliebene notwendig. So können persönliche Ressourcen gebündelt und Räume für neue Innovationen entstehen. Dabei ist jedoch zu bemerken, dass die Kleinstädte hier personell und finanziell bereits jetzt an ihre Grenzen kommen. Hierbei ist noch einmal auf die Relevanz der Rückwanderung, nicht nur für die Kleinstädte, sondern auch für die umliegende Region zu betonen. Es ist demnach nicht nur Sache der Kommunen, hier aktiv zu werden. Sie sind hierbei auch auf die politische Unterstützung auf Kreis- und Landesebene angewiesen.Small towns in rural, economically disadvantaged regions face intricate challenges driven by demographic shifts, economic difficulties, and social upheavals. In recent years, return migration, emerging as the predominant form of immigration in these areas (cf. Meister et al. 2020), has gained increasing significance. Moreover, the approach to the topic, particularly in the promotion of return migration, has evolved remarkably (cf. G3 (1) 2023). Return migration no longer solely serves the stabilization of population numbers but also holds significant potential for local and regional development. This study explores the role of returnees in the development of small towns and investigates the contributions they can make. The research is based on a theoretical approach where the impact areas of return migration (economy, culture and social aspects, education and knowledge transfer, as well as networking) are discussed and examined through qualitative interviews with returnees and representatives of various small towns. The results reveal that despite similar conditions in return migration promotion, small towns are at varying stages. The perception of the impact areas of return migration, especially in terms of added value for the towns, varies widely. The focus is predominantly on the short-term effects of return migration in the context of promotion and support measures, which, however, do not address the fundamental, often structural issues of small towns. The potential of return migration manifests primarily in long-term effects. Returnees present themselves as dedicated individuals who can contribute to city development even after their return and thus contribute to a positive, development-oriented environment. While small towns acknowledge this potential, it is not yet integrated into promotion and support measures. The challenge lies not only in supporting projects initiated by enthusiasts but also in adapting meeting and community spaces to the needs of returnees, as well as those who have stayed; given their increasing commitments to family and work. Therefore, personal resources can be pooled, and spaces for new innovations can emerge. However, it is important to note that small towns are already stretched to their limits in terms of personnel and finances. Therefore, emphasizing the relevance of return migration is crucial, not only for small towns but also for the surrounding region. Hence, it is not solely the responsibility of municipalities to take active measures, it also relies on political support at both district and state levels

    Dispelling the Myths Behind First-author Citation Counts

    We 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

    We 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
