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 textThrough a research collaboration with Atomos SpA, an Italian software vendor of Advanced Planning Systems (APS), authors have developed a tool in order to perform a tactical finite capacity planning over a multi-site production system as well as to optimize outsourcing volumes in order to drive supply logistics chain. The main objective of this tool, called Expert Plan (EP), is to balance capacity over different resources and to plan production supply requirements in order to determine the minimum cost for Master Production Schedule (MPS) and to match internal and external capacity of production system with customer and supplier constraints. Production balance is obtained through a performance driven analysis by using On Line Analytical Processing (OLAP) server allowing users to compare the result of each planned scenario. The output of this process is MPS. It is used to feed both Material Requirement Planning and Critical Resource Planning (MRP/CRP) and to define available production profiles for Available To Promise/Capable To Promise (ATP/CTP) procedures. The aim of the paper is to describe architecture functionalities in order to highlight its potential use in the APS market. Finally authors outline OLAP benefits for performance driven analysis. A first complete prototype is now under laboratories testing, while a simpler application module has been implemented in several medium industries in order to test its effectiveness

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
