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 textPlanned lead time determination in a make-to-order remanufacturing system
No full textIn recent years, remanufacturing has emerged as an important research area, due to the tendency of stricter environmental regulations in industry and the awakening to the economic attraction of recovering the products rather than the disposal alternative. This also requires developing manufacturing planning and control techniques to improve the performance of remanufacturing systems.
In order to reassemble finished products, new components are required since the recovery rate of return components can never reach 100%. When making a disassembly and procurement decision, we then need to balance the inventory holding cost and stockout cost. In the meantime, the process lead time depends on which disassembly and procurement option that is chosen. In this paper, we study a system where remanufacturing is driven by customer orders. A disassembly order is always released first and then the disassembly result determines whether a purchasing order is needed. Our objective is to examine the process lead time, which can be used to determine the planned lead time in production planning and control of remanufacturing. We start with disassembling a single-component case and then extend the model to a two-component scenario. We also investigate how the disassembly yield influences the system performance. Results of this study are intended to be implemented in a real-world engine remanufacturing environment
