Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
State of the Art on Allocation in LCA and Proposals for Changes in ISO 14044
No full textA literature review is presented in relation to the system expansion and the allocation of the environmental burdens in life cycle assessment (LCA). Many research centers in Europe and the world undertook subject of multi-functionality. Diversity of solutions and approaches is a barrier to an LCA practitioner who do not specializes in the subject related to multifunctionality and allocation. Wealth of literature and the progress made in the methodology create the need to systematize this issues. In the paper, various approaches and methodologies used in the life cycle analyses of multi-functional processes proposed in scientific papers, guides and manuals were compared. Recommendations related to the problem of multifunctionality of processes and systems which were identified in the literature were analyzed for compliance with the hierarchy of preferred solutions recommended in the ISO 14044, which arranges different solutions of multi-functionality from the most to the least recommended basing on the possibility of its implementation. Dependence of a choice of multifunctionality solution on approach to analysis: attributional analysis (ALCA) and consequential analysis (CLCA) was analyzed. Issues related to the use, advantages and disadvantages of an allocation on the basis of physical and economic relationships and of the system expansion (avoided emissions, substitution) were discussed closely. It is found on the basis of literature that in practice a procedure of solving multi-functionality mainly depends on context of analysis and the classification of the analyzed system. It has been shown that “Allocation procedure” of the ISO 14044 in relation to the literature is out of date and needs to be completed and changes. Finally, proposed changes and additions to the ISO 14044 resulting from the literature review were presented.Praca obejmuje przegląd literatury związanej z alokacją obciążeń środowiskowych oraz poszerzeniem systemu wyrobu w ocenie cyklu życia. Tematyka była wielokrotnie poruszana przez ośrodki europejskie i światowe, jednak bogactwo literatury i postęp w dziedzinie metodyki stwarzają potrzebę usystematyzowania tego zagadnienia. W pracy porównano różne podejścia i metodologie stosowane w analizach cyklu życia procesów wielofunkcyjnych proponowane w publikacjach naukowych, przewodnikach i podręcznikach. Zalecenia związane z problemem wielofunkcyjności procesów i systemów zidentyfikowane w literaturze przeanalizowano pod kątem zgodności z hierarchią preferowanych rozwiązań zalecaną w normie ISO 14044. Przeanalizowano zależność wyboru rozwiązania wielofunkcyjności od podejścia do analizy, m.in.: analiz opisowych (attributional) oraz skutkowych (consequential). Omówiono zagadnienia związane ze stosowaniem alokacji w oparciu o zależności fizyczne i ekonomiczne oraz poszerzenia systemu (emisji unikniętych, substytucji), przedstawiono ich zalety i wady. Stwierdzono, że w źródłach literaturowych wybór rozwiązania wielofunkcyjności zazwyczaj jest zależny od celu i kontekstu analizy. Wykazano, że „Procedura alokacji” normy ISO 14044 w świetle literatury przedmiotu wymaga uzupełnienia. W pracy zaproponowano zmiany i uzupełnienia w normie ISO 14044 wynikające z przeglądu literatury przedmiotu
Variations on the Author
No full text“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
No full textWe 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
No full textWe 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
