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
Safety as Airline Business Aspect: From Data to Action by A Value Model for Big Data and Feedback Method for Small FlightStories
No full textThis thesis proposes the of integrating safety, economics, and passenger experience and draws on the author's research and experience in aviation to develop a more comprehensive approach to airline business management. The research closes the gap between business and Safety Management Systems in airlines by introducing two novel and complementary concepts: the Airline Value Production Management Model and FlightStory as a tool to enable pilots as intelligent feedback providers.The thesis discusses two interconnected research projects aimed at improving safety and efficiency in airline operations. The first project, AVPMM, focuses on network performance management, while the second project, FlightStory, aims to empower flight crew as intelligent feedback providers.This research thesis focuses on airline safety and value production management, with an emphasis on using big data and feedback methods to improve safety and value production. The author presents a specific solution called FlightStory, which empowers flight crew as intelligent feedback providers. The thesis includes a literature review, research questions and methods, and an evaluation of FlightStory's effectiveness. The AVPMM model is proposed as a logical extension of the increase of lower specific levels into network, region, route, and flight. The thesis also discusses the challenges of conducting research in a company context and provides recommendations for further research.The author shares three war stories from their experience in the aviation industry, highlighting common problems in safety management during flight operations and how it relates to network business decisions. The author aims to develop a new solution for integrating safety and business management in international commercial aviation.The thesis discusses the challenges of current feedback systems in aviation safety reporting, including the reductionist approach, the lack of qualitative data, and the bias towards Safety-I events. The review suggests the need for a reporting system that collects organizational factors and takes safety out of its silo and into the context of other key performance indicators. The author developed an app designed to collect FlightStory data from the crew, inspired by sensemaking and storytelling concepts.The thesis proposes an Airline Value Production Model for managing safety in the business context of value production. The review also discusses the lack of an explicit value production model and the need to manage safety as a business aspect, integrated with other essential variables such as economy and customer experience.The research projects provide innovative feedback methods and an integrated approach to value production management, which can be viewed as disruptive innovations. The thesis concludes with a vision of a Value Production Centre (VPC) that integrates business and safety management using the AVPMM model. The VPC aims to provide a holistic approach to value production management, where safety is not just a compliance issue and operational constraint but an integral part of the business strategy. The thesis provides a valuable contribution to the aviation industry by proposing a new approach to safety management that integrates with business management and value production. The FlightStory app and AVPMM model offer practical solutions for improving safety and efficiency in airline operations, and the research provides a foundation for further development and implementation of these solutions
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
