Matteo Morganti, Combining Science and Metaphysics. Contemporary Physics, Conceptual Revision and Common Sense
Full text linkThe aim of this article is to review and discuss Matteo Morganti's "Combining Science and Metaphysics. Contemporary Physics, Conceptual Revision and Common Sense". I will offer a presentation of the issues that the author discusses. I will also provide a critical analysis of the arguments that are defended in the book, and of the case studies suggested in the second part of the book.Lo scopo di questo articolo è quello di recensire e discutere il libro di Matteo Morganti "Combining Science and Metaphysics.

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
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
The Underdetermination of Metaphysics by Physics (An Open Problem With a Case Study)
Full text linkThe aim of this paper is to discuss the problem of the underdetermination of metaphysics by physics. It is, in fact, possible to show that different metaphysical options are available to interpret the same physical theory. However, physics cannot help to decide which is the most correct one. In particular, in this paper I will focus on the case study of quantum field theory (and its algebraic formulation). I will show that there are at least two metaphysical theories that can be considered as legitimate interpretations of the theory. Yet, no choice can be made between them by only physical means, and we need to appeal to non-empirical criteria. I will show why such criteria are not eventually compelling from a naturalistic perspective. I will conclude the paper with a proposal of a pragmatic solution to this open problem.Lo scopo di questo articolo è discutere il problema della sottodeterminazione metafisica da parte della fisica. È, infatti, possibile mostrare che sono possibili diverse opzioni metafisiche per interpretare la stessa teoria fisica. Tuttavia, la fisica non permette di decidere quale tra queste sia la più corretta. In particolare, in questo articolo mi concentrerò sul caso studio della teoria quantistica dei campi (e della sua formulazione algebrica). Mostrerò che ci sono almeno due teorie metafisiche che possono legittimamente essere considerate come interpretazioni della teoria. Tuttavia, non si può scegliere tra le due grazie solo alla fisica, e abbiamo bisogno di utilizzare dei criteri non-empirici. Mostrerò perché tali criteri non sono in ultima analisi convincenti dal punto di vista di una prospettiva naturalistica. Concluderò l’articolo con una proposta per una soluzione pragmatica a questo problema aperto
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
