Landscape Agronomy - Advances and Challenges of a Territorial Approach to Agricultural Issues
No full textThe landscape is widely identified as a relevant target both by integrative policies and across the disciplines dealing with resource management and territorial planning. Landscape agronomy promotes a greater involvement of agricultural sciences into this arena by increasing the attention on the dynamics relating the farming practices to the natural resources and the temporal and spatial patterns of land covers.
This book covers the background that improved the transdisciplinary interface of agronomy with spatially-explicit disciplines like landscape ecology and geography both in research and in training programs, in addition to some experiences of participative landscape management. On these bases, the state of art on cutting-edge data availability and methodological issues is used to select and discuss some worldwide case studies.
This selection of research topic examples underpins the concluding discussions about challenges ahead. Researchers as well as policy and decision makers are the main target of this book that seeks to provide a toolbox of concepts, examples and ideas to improve the understanding of agricultural landscapes. Agricultural activities manage the greatest share of land surface on Earth with fast-paced changes compared to any other human land use. With this book we aim at providing a stronger interface between agricultural science and landscape design processes

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
