A classification procedure for exploitable reserves
No full textProposes a classification procedure for minable reserves for use by mining companies. After reviewing resource/reserves concepts and definitions, the interrelationship between reserves and mining project is examined with a view to establishing a classification based on: a) considerations of economic feasibility, and b) level of confidence of the design itself. The described approach relies on the probabilistic evaluation of Net Present Value (NPV) and is presented as an operational procedure for recognizing and characterizing the random technical and economic magnitudes of mine designs with particular reference to the reserves. -Author

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
