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
A Sustainable EOQ Model for Repairable Spare Parts Under Uncertain Demand
No full textAbstract: Many contributions could be found in scientific literature about logistics and inventory management of spare parts, but there is a lack of attention on the sustainable issues. This paper investigates how the single-product replenishment problem can be formulated and solved including sustainable concerns in the inventory model. The problem has been studied in case of stochastic variability of the consumption rate of repairable spare parts. The optimal order quantity is derived by minimising a sustainable logistic cost function in which economic and environmental costs of both the options of repairing and purchasing new spare parts are considered. Traditional logistic costs of spare parts (purchase, ordering, transport, holding and repair) as well as environmental costs due to transport, production, and disposal of replaced ones are considered. Furthermore, since demand of spare parts is uncertain and assumed to be an independent stochastic variable in each period of the supply lead time, shortage costs due to stock out events are considered. The optimal means of transport, the optimal repair policy, as well as the corresponding optimal value of the sustainable economic order quantity (SOQ) are calculated. A numerical example derived from field industrial data is presented to test the model capabilities. Results are discussed and compared with classical EOQ model solution
A Comprehensive Voltage-Behind-Reactance Model of Twelve-Phase Synchronous Motors
No full textThe increased interest gained by the multiphase (MP) machines in recent years is justified by their potential advantages. With respect to three-phase machines, the multiphase ones have lower phase currents for a given power thus requiring reduced semiconductor switch ratings. Additionally, they show fault-tolerant behaviour thanks to the intrinsic redundant structure. Therefore, the drive reliability can be greatly enhanced since the machine can continue to operate even if one or several phases are lost. The definition of circuital-based machine models enables the simulation of single phase or multiphase faults. This feature is essential for the development of control strategies exploiting MP fault-tolerant capabilities through the additional degrees of freedom. This paper proposes a machine model based on the voltage-behind-reactance (VBR) modelling approach that properly accounts for the multiple mutual couplings between the machine phases. Simulation results are provided for a quadruple three-phase synchronous motor
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

No full textAppropriate 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
