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
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
The paradigm of management, management systems, and resource stewardship
No full textThe idea of ''management'' is central to our understanding of how people interact with their resources, but many challenges have arisen to traditional concepts of western, science-based resource management. Management is a set of actions taken to guide a system towards achieving desired goals and objectives. A Management System is the sum of these actions, goals and objectives, the process through which they are legitimized by social norms, and the institutions and actors involved in carrying them out. Reframing the concept from management to management system provides a tool for better understanding how social and ecological dynamics act as coupled drivers of managed ecosystems. Seen from this perspective, there are strong parallels between the traditional resource management systems of indigenous peoples and western science-based management systems. Stewardship is a western concept which resonates with the foundations of traditional resource management systems. Both systems of management can be understood on gradients of human influence on ecosystems and of management intensity. Sustainability can emerge across various locations along these gradients. Achieving an integrated understanding of the coupled dynamics of social and ecological systems is a central challenge for both managers and for researchers. Key words: traditional resource management system, western science-based management system, management failure, stewardship, sustainability. La idea de ''manejo'' es central para nuestro entendimiento de cómo la gente interactú a con sus recursos. Sin embargo, muchos retos han surgido a los conceptos tradicionales occidentales sobre el manejo de recursos basados en la ciencia. Manejo es un conjunto de acciones tomadas con el fin de guiar un sistema para alcanzar metas y objetivos deseados. Un Sistema de Manejo es la suma de estas acciones, sus metas y objetivos, el proceso a través del cual éstas se legitiman por normas sociales, y las instituciones y actores involucrados en llevarlas a cabo. Replantear el concepto de manejo por el de sistema de manejo proporciona una herramienta para el mejor entendimiento de cómo las dinámicas sociales y ecológicas actú an como conductores acoplados de los ecosistemas manejados. Desde esta perspectiva, existen fuertes paralelismos entre los sistemas tradicionales de manejo de recursos de los pueblos indígenas y los sistemas de manejo occidentales basados en la ciencia. Stewardship es un concepto occidental que armoniza con las bases éticas de los sistemas tradicionales del manejo de recursos. Ambos sistemas de manejo pueden ser entendidos como gradientes de influencia humana sobre los ecosistemas y la intensidad de manejo. La sustentabilidad puede emerger en varios puntos a lo largo de estos gradientes. Alcanzar un entendimiento integrado de la dinámica acoplada de los sistemas sociales y ecológicos es un reto central tanto para manejadores como para investigadores
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
