Linking marine and terrestrial ecosystem services through governance social networks analysis in Central Patagonia (Argentina)
Full text linkThe complex relationship among diverse natural factors in a given ecosystem and with society could be not explicitly reflected in governance actions and policy. Social networks are useful tools to characterize these links but few studies include social and ecological nodes. We applied social network analysis to characterize governance and use networks in a coastal socio-ecological system while testing (i) if governance links reflects ecosystem services (ES) use links, (ii) if social links reflect ecological relations between continental and marine ES and (iii) if relations among social actors are associated with their use of and participation in the management of ES. We use structured interviews to build one-mode use and governance networks with social actors and two-mode networks relating social actors and ES. Our results showed cohesive, low density and centralized networks of governance and use. We found that actor-actor links reflect ecological relations between continental and marine environment, but actor-actor relations are weakly correlated with those derived from actor-ES relations, meaning that actors with common interest about ES are no necessarily working together. This paper also shows that social networks are useful to highlight gaps and paths to move the system toward more effective co-management structures.Fil: Alonso Roldán, Virginia.

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
Social-ecological shifts, traps and collapses in small-scale fisheries: Envisioning a way forward to transformative changes
Full text linkSmall-scale fisheries (SSF) are critical to food systems and livelihoods. However, the relation between fisheries
resilience, outcomes of proximate and distal drivers and the potential space for transformative changes have been largely unexplored. Such knowledge is key to understanding how fishery resources, institutions and actors
respond to, and learn from, diverse drivers of change and social-ecological crises, as well as to design policies
aimed at building resilience in SSF. This paper provides a new heuristic model to analyze the factors that combined lead SSF to trajectories towards shifts, traps and collapses, including the opportunity to navigate sustainable transformations. We illustrate the proposed Heuristic with three case studies with different biophysical and socio-cultural contexts and final outcomes: the Galician shellfisheries on foot (Spain), the Chilean king crab small-scale fishery (Chile), and the Galapagos sea cucumber small-scale fishery (Ecuador). The application of the Heuristic and a detailed description of model key elements for each case study provide
practical examples and a valuable guide for fisheries scientists, practitioners and decision-makers to learn and/or respond in a flexible way to SSF social-ecological crises in the pursuit of fisheries sustainability and equity. Scholars are welcome to adopt our Heuristic to classify and bound SSF, order events, suggest hypotheses of linked drivers, pathways of change, potential trajectories, and outcomes, and envision potential space for transformative changes
