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
PRACTICAL PROCESS NON-CONFORMANCE DETECTION
Full text linkThis paper represents the culmination of a thorough investigation into the existing technological methodologies to solve process non-conformance detection. We explore how to develop this knowledge into an approach that offers a useable, practical solution. Process non-conformance detection research has been explored fairly sparingly and sporadically from around 1995 until now. The work presented in the literature, while technically effective at detecting non-conformance seemed to be practically unviable for a variety of reasons. In this paper we address why the detection of process non-conformance is valuable for process improvement, we examine the practical shortcomings in the existing solutions, explain why these shortcomings exist and how these approaches have failed to provide practical value in various ways. We explore the issues currently related to this research area that withhold process non-conformance detection from being practically useful, and present our own approach that addresses these issues. Our approach involves a generic and practical method of specifying rules that describe how enactment data is to be checked for any non-conformance instances that may have occurred. The approach is designed to cater for practical considerations such as timely detection, minimal interference, and minimal required effort while remaining separate from the process specification. We support this claim via two case studies that test our assertions and demonstrate how process non-conformance detection is valuable for process improvement. Furthermore, we show how a process may be improved by the approach using the result data from several hundred process enactments done both before and after the approach was integrated. The result data from these two phases is provided and 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
