Spaces and ethics in the Common Agricultural Policy
No full textThe “moral turn” in Geography, recognized by David Smith in 1997, is now established in geographical research, articulating in the different approaches of investigation. It has also encouraged studies on ethical choices in agricultural practices, crop and livestock farming; such studies are demonstrating, for example, important changes in the distributive patterns of agriculture, in terms both of sale of products, and in consumption.
We propose to examine the Common Agricultural Policy in ethical terms, and to consider their effects in the choises of farmers and consumers
Common agricultural policy role and value in a changing world. Food – agriculture – environment as key factors in order to get through the current global economic crisis

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

No full textPossible occurrence of low-angle normal faults in Central and Northern Greece
No full textDuring the elaboration of the Greek Database of Seismogenic Sources (Gre.Da.SS) (Pavlides et al., 2010; Sboras et al., 2009) many active faults of Central and Northern Greece were analysed in detail either from literature sources or new field data in order to reassess their principal seismotectonic parameters. Based on the great amount of information gathered for the database and especially on its good uniformity, in different and distinct areas of central and northern Greece it is possible to observe fault systems very similar in terms of geological setting and structural pattern. For these crustal volumes, the collected data suggest the occurrence of parallel synthetic, and sometimes antithetic, faults merging at depth on low-angle fault planes. The fault geometry, kinematics and tectonic evolution of these regions were compared with the well-known (and widely accepted) detachment fault zone characterising the Gulf of Corinth. In continental central-northern Greece, at least three other regions, from which the two have been already more or less explicitly suggested by other authors, are probably associated with low-angle faulting at depth. The occurrence of a low-angle shear zone has important consequences not only for the geodynamic processes and the crustal extension behaviour, but also for seismic hazard assessment (SHA) estimations
