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

No full textRisk and crisis management in the reformed European agricultural policy
No full textCurrently there is ample discussion among EU Institutions (European Commission, European Parliament, and Member States' governments) on the opportunity for setting up a comprehensive EU-wide framework on risk and crises in agriculture. In the meantime, within the limits of the WTO rules on agriculture, national governments are allowed to intervene through direct compensation to farmers in case of exceptional events that cause damages to farming operations and through subsidies to crop insurance programs. Such schemes are quite expensive for domestic budgets and some Member States are trying to switch some of their cost to the Community's budget, although an expansion of financial resources devoted to agriculture in Europe is rather unlikely. Moving from the recently emanated proposal of the European Commission, this paper discusses the main issues related to public intervention for risk and crises management in agriculture. © 2007 Canadian Agricultural Economics Society
