Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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

Get PDFAppropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Get PDFWe 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
Environmental Ethics and the Need for Theory
Get PDFEnvironmental ethics calls into question whether moral obligations invariably arise within relationships and communities, and whether wrong can only be done if some identifiable party is harmed. The aim of this paper is to appraise these assumptions, to argue for negative answers, and to draw appropriate conclusions about the scope of moral standing (or moral considerability). Its findings include the conclusions that our moral obligations (or responsibilities) extend to people and non-human creatures of the foreseeable future, as far as the impacts of present actions and policies can themselves be foreseen, that, that moral standing attaches to the possible people and other living creatures of the future, and (with Derek Parfit) that ethics is to some degree impersonal, being concerned with future quality of life for whoever lives in future centuries, whether they are currently identifiable or not. This in turn requires sustainable forms of social practice and of the human population. Another conclusion is that these findings are compatible with the approach of stewardship which the author has defended elsewhere, since stewardship need neither be anthropocentric nor managerial, and precludes current and future human agents treating the natural world as we please.Environmental ethics calls into question whether moral obligations invariably arise within relationships and communities, and whether wrong can only be done if some identifiable party is harmed.

Celem tego artykułu jest ocena tych założeń, argumentacja na rzecz negacji tego stanowiska oraz wyciągnięcie odpowiednich wniosków na temat zakresu stanowiska moralnego (lub moralnej doniosłości). Opracowanie to wskazuje, że nasze moralne obowiązki (lub odpowiedzialność) rozciągają się na ludzi i przyrodę pozaludzką w dającej się przewidzieć przyszłości, o ile można przewidzieć wpływ obecnych działań i polityk, że takie stanowisko moralne może dotyczyć ludzi i innych żywych stworzeń w przyszłości oraz (za Derekiem Parfitem), że etyka jest do pewnego stopnia bezosobowa i dotyczy także przyszłej jakości życia każdego, kto będzie żył w przyszłości, niezależnie od tego, czy można te istoty obecnie zidentyfikować, czy nie. To z kolei wymaga trwałych form praktyk społecznych i populacji ludzkiej. Kolejnym wnioskiem jest to, że odkrycia te są zgodne z podejściem zarządzania (stewardship), którego autor bronił w innym miejscu, ponieważ zarządzanie nie musi być ani antropocentryczne, ani kierownicze, i nie musi wykluczać obecnych i przyszłych ludzi traktujących dowolnie świat przyrody.Environmental ethics calls into question whether moral obligations invariably arise within relationships and communities, and whether wrong can only be done if some identifiable party is harmed.
