Hacia una socioecología del bosque nativo en Chile
No full textThis book arises from four case studies developed from the O'Higgins region to the Los Ríos region, which provide different perspectives on the use of forests and their biodiversity. In the first chapter, the author delves into the concept of socioecology and the denial of the community-forest link, and brings them to the light of the Chilean context. In the second chapter, the authors differentially analyze "the hill" and the native forest, in the communes of Doñihue, Coltauco and Las Cabras (O'Higgins region), as experienced by its various users. The third chapter presents the case of two neighboring communes, but diametrically different in terms of native forest management, such as El Carmen and Pinto in the Ñuble region. The fourth chapter describes and analyzes the different users of native forest in the Panguipulli commune, their history and conflicts, while the fifth and final chapter attempts to understand the Mapuche vision regarding their mawiza. In the latter, the knowledge of an ancestral people and their particular vision of governance, of what we (non-Mapuche) call native forest are balanced.PublishedEste libro surge a partir de cuatro estudios de caso desarrollados desde la región de O´Higgins hasta la región de los Ríos, que entregan diversas miradas respecto al uso de los bosques y su biodiversidad. En el primer capítulo, el autor se adentra en el concepto de la socioecología y de la negación del vínculo comunidad-bosque, y los trae a la luz del contexto chileno. En el segundo capítulo, los autores analizan diferencialmente “al cerro” y al bosque nativo, en las comunas de Doñihue, Coltauco y Las Cabras (región de O´Higgins), según lo experimentan sus diversos usuarios. En el tercer capítulo se presenta el caso de dos comunas vecinas, pero diametralmente distintas en lo que respecta a la gestión del bosque nativo, como son El Carmen y Pinto en la región del Ñuble. En el cuarto capítulo se describen y analizan los distintos usuarios de bosque nativo en la comuna de Panguipulli, su historia y conflictos, mientras que, en el quinto capítulo y final, se intenta comprender la visión mapuche con respecto a su mawiza. En este último, se ponen en balanza los saberes de un pueblo ancestral y su particular visión sobre la gobernanza, de lo que nosotros (los no-mapuche) llamamos bosque nativo

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
Protocolo de restauración de corredores biológicos para polinizadores
No full text44 páginasReconociendo el importante rol de la polinización en la regeneración de los bosques nativos, este documento presenta una propuesta metodológica basada en corredores biológicos donde se puedan iniciar acciones de restauración de bosques nativos, las cuales, además de facilitar el proceso de recuperación de los bosques, ayuden a la conservación de la biodiversidad y de especies polinizadoras en Chile
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
