Governance of the Cassurubá Extractive Reserve, Bahia State, Brazil: An analysis of strengths and weaknesses to inform policy
Get PDFThis study analyzed the governance of the Cassurubá Extractive Reserve or RESEX in Bahia State, Brazil, exploring the favorable conditions and the difficulties faced by this newly established and complex governance system. RESEXs are protected areas that involve traditional communities in its administration through majority representation in a Deliberative Council (DC). Research was conducted through literature and documents review, participant observation through direct involvement in community activities along several years (2008–2016), and semi-structured and structured interviews applied respectively to members of the DC and to users of the RESEX during 2012 and 2013. The Institutional Design Principles were used as an analytical tool to reflect on the strengths, limitations, and the multiple factors affecting its governance. Interview results suggest a more negative perception of resource users about RESEX functioning and prospects than DC members. Participation of resource users in RESEX meetings was low and a passive performance of council members was observed. Since 2012–2013, participation of users and council members has been gradually increasing. Several of the design principles were found to be present (boundaries, congruence, collective arrangements though enhanced participation is needed, conflict resolution mechanisms, recognition of rights to organize, nested enterprises), and only two were deemed insufficient or mostly absent: monitoring (4A and 4B), but improving in terms of community participation in vigilance, and graduated sanctions (5), present in legislation but hardly implemented. Further studies should be pursued for continuing adding blocks to the understanding of CPR governance systems with diverse degrees of complexity.Fil: Nobre, Danieli Marinho.

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
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
