Agricoltura, alimentazione, ambiente: come mantenere la "tripla A" al tempo della crisi?
No full textThe increasing food demand leads to an increase of the world food production. Nevertheless, there is the fear that neither yield increases nor exploitation of new croplands will be able to cope with this need. The ongoing changes will decrease the agricultural productivity of some areas (the Mediterranean among these), due to a lower soil fertility and water availability, whereas others will get an advantage, mainly in the north. On the other hand, the demand for meat is still rising, thanks to better living conditions in emerging countries. However, meat production, particularly livestock, has an important impact on climate as well as on the environment. Moreover, “energy crops” not only help questionably to reduce greenhouse gas emissions, but they have already shown a negative impact on prices of food cereals. With this background, a new version of “Decide” game has been created on the theme of sustainable agriculture, emphasizing the topic of resource consumption and greenhouse gas emissions

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
