    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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

    Sustainable Procurement: knowledge and practice towards sustainable development. Giappichelli (in pubblicazione)

    In recent decades, sustainability has become a goal to be achieved throughout the world; it is a direction into which efforts are to be put to solve the global challenges that people are facing today. The spectrum of Sustainable Goals is extensive and wide, ranging from poverty reduction, to human rights and equality of opportunity, and to environmental issues, such as biodiversity conservation, energy efficiency, climate mitigation and adaptation, and waste reduction (see, among others, UNEP, 2017 and UNOPS, 2017). The concept of sustainability has emerged since the 1970s. Today, it has become a crucial paradigm in supply chain management (SCM) (Seuring and Müller, 2008) and is also the foundation for one of the most significant international cooperation initiatives (i.e. the agenda for Sustainable Development Goals 2030), which explicitly highlights procurement as an effective way to support the achievement of sustainable objectives. Indeed, a variety of activities and processes have been substantially influenced and involved, and “procurement” is one of them. Leveraging procurement to achieve sustainable objectives by integrating related requirements, specifications and criteria that are compatible and in favour of the protection of the environment, of social progress and in support of economic development, namely by seeking resource efficiency, improving the quality of products and services and ultimately optimizing costs, beyond the acquisition of works/products/services to merely satisfy organization’s requirements, is defined as sustainable procurement (SP) 1. To achieve these social and environmental objectives, both public and private organizations ought to integrate sustainable considerations and principles into their procurement processes; also, procurement plays a crucial role as sustainability policies and practices should extend beyond organizations’ boundaries. In light of the demand to include sustainable principles within the procurement practice on the one hand, and the complexity of operations and required knowledge and understanding on the other (Carter and Rogers, 2008), there is growing interest in exploring and investigating how SCM and procurement in both the public and private sector can be en- 1 UN global marketplace, see https://www.ungm.org/Shared/KnowledgeCenter/Pages/PT_SUST 10 couraged to practice sustainably and reduce their social and environmental footprint. In the private sector, the purchasing function plays a strategic role in helping a firm reach its sustainable development objectives, as acknowledged by an increasing body of research and publications on sustainable procurement (e.g. Walker and Phillips, 2009). More recently, research attention has moved to commitment to sustainability both through supply chain management and measurement. In the private sector, there is a long history of research on corporate social responsibility and the bulk of sustainable SCM research is concerning environmental issues; social issues are also examined broadly. With regard to public procurement, until recently, how effective policy initiatives have been has driven supply chain sustainability management and measurement, given the large scale of public procurement and its capability to achieve sustainable goals across supply chains (Amann et al., 2014). This book is about how procurement performs as an effective tool in the pursuit of sustainability objectives, in particular environmental goals. The term “procurement”, in this book, is defined in a broad sense and is in line with the “umbrella” usage of the term (Snider and Rendon, 2012). “Procurement” here encompasses all dimensions of the acquiring activities for products, works and services, including management of the organization’s supply, e.g., sourcing in supply chain, outsourcing, private and public partnership etc., Within this range, topics investigated in the book loot at sustainable procurement practices in both public and private sectors, including innovative and practical experience and retrospective academic research findings in these fields, which provide knowledge and perspectives on some specific issues of SP

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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

    We 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
