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
Eine empirische Mehrebenenuntersuchung der Auswirkungen des neuen Arbeitsmodells vor dem Hintergrund von längerfristigen Arbeitsmarktentwicklungen und individuellen Nutzungsformen
Full text linkDie vorliegende Arbeit untersucht die Bedeutung und Auswirkungen von Plattformarbeit in Westeuropa und Nordamerika. Dafür werden die Zusammenhänge zwischen drei Ebenen untersucht: Erstens die Gestaltung des Arbeitsmodells als Mesoebene, zweitens bestehende Arbeitsmarktentwicklungen und nationale Regulierungskontexte als Makroebene, sowie drittens das Leben und Erleben des Arbeitsmodells von Plattformarbeiter*innen als Mikroebene. Die empirische Untersuchung konzentriert sich auf Crowdwork als ortsunabhängige Form von Plattformarbeit. Zudem wird eine Triangulation von qualitativen und quantitativen Forschungsmethoden sowie eine komparative Perspektive zwischen unterschiedlichen Aufgabenkomplexitäten (Mikro- und Makroaufgaben) und institutionellen Kontexten (Deutschland und USA) genutzt.
Die Mehrebenenuntersuchung zeigt, dass Plattformarbeit auf der Mesoebene eine arbeitsorganisatorische Innovation darstellt, die auf der Makro- und Mikroebene an bestehende Entwicklungen anknüpft. Auf der Mesoebene zeigen sich vielfältigere und komplexere Ansätze der Arbeitsorganisation und Arbeitskontrolle als häufig angenommen. Auf der Makroebene knüpft Plattformarbeit an bestehende Prozesse der Auslagerung, Flexibilisierung und Prekarisierung von Arbeit, wobei der nationale Regulierungskontext weiterhin prägend ist. Auf der Mikroebene zeigt sich, dass die Heterogenität der Plattformarbeiter*innen und das hohe Maß an Eigenverantwortung ihre Individualisierung befördert.
Die vorliegende Arbeit schlussfolgert, dass eine Plattformisierung der Arbeitswelt keineswegs gegeben ist. Die Bedeutung von Plattformarbeit wird insbesondere darin verortet, dass es die weitere Ausbreitung und Ausdifferenzierung von prekären Erwerbsformen auf der Makroebene und die Individualisierung von prekär Erwerbstätigen auf der Mikroebene befördert. Die vorliegende Arbeit verortet in dieser Vielfalt an Prekarität und Individualisierung der Prekären eine Form von Herrschaft.This study examines the importance and consequences of platform work in Western Europe and North America. To this end, the connections between three levels are examined: First, the design of the work model as the meso level, second, existing labour market developments and national regulatory contexts as the macro level, and third, the forms of use and perceptions of platform workers as the micro level. The empirical investigation focuses on crowdwork as a location-independent form of platform work. Furthermore, the study uses a triangulation of qualitative and quantitative research methods as well as a comparative perspective between different task complexities (micro and macro tasks) and institutional contexts (Germany and USA).
The multi-level investigation shows that platform work represents an innovation at the meso level that reflects and reinforces existing developments at the macro and micro levels. At the meso level, more diverse and complex approaches to work organization and control emerge than is often assumed. At the macro level, platform work reflects and reinforces processes of outsourcing, flexibilization and precarisation of work, though the national regulatory context remains a central factor. At the micro level, the heterogeneity of platform worker and the high degree of personal responsibility promotes their individualization.
The study concludes that a platformisation of work is far from certain. The study attributes the importance of platform work to the fact that it promotes the further spread and differentiation of precarious employment at the macro level and the individualization of precarious workers at the micro level. The study identifies this variety of precarity and individualization of the precarious as a form of domination
