The Place of the De motu in Aristotle's Natural Philosophy
No full textThe opening lines of the Meteorology suggest that Aristotle was centrally concerned with the integration of a range of different natural investigations into a single program of study. This essay will attempt to illustrate how this integration is achieved by looking at the place of the De Motu Animalium (hereafter De Motu) in Aristotle’s natural philosophy. At least at first sight, this short but difficult treatise does not seem to be a very promising case. It has been argued that the De Motu does not belong to natural philosophy (or to any other Aristotelian science for that matter). On this interpretation, the De Motu would be an “interdisciplinary work” or even “a [deliberate and fruitful] departure from the Organon model” (Martha Nussbaum, Aristotle’s De Motu Animalium. Princeton 1978: 113). Hopefully, a fresh look at the opening lines of the De Motu will help, not only to establish that it pertains to natural philosophy, but also to show how it contributes to the explanatory project pursued by Aristotle
The Modern Aristotle: Michael Polanyi’s Search for Truth against Nihilism
No full textDavid Hoinski and Ronald Polansky’s “The Modern Aristotle: Michael Polanyi’s Search for Truth against Nihilism” shows how the general tendencies of contemporary philosophy of science disclose a return to the Aristotelian emphasis on both the formation of dispositions to know and the role of the mind in theoretical science. Focusing on a comparison of Michael Polanyi and Aristotle, Hoinski and Polansky investigate to what degree Aristotelian thought retains its purchase on reality in the face of the changes wrought by modern science. Polanyi’s approach relies on several Aristotelian assumptions, including the naturalness of the human desire to know, the institutional and personal basis for the accumulation of knowledge, and the endorsement of realism against objectivism. Hoinski and Polansky emphasize the promise of Polanyi’s neo-Aristotelian framework, which argues that science is won through reflection on reality.</p
Generalized Polansky Index as an Aromaticity Measure in Polycyclic Aromatic Hydrocarbons
No full textIn this work, the ideas of molecular quantum similarity are used to generalize the Polansky similarity index. The newly developed index gauges the aromaticity of individual benzenoid rings in polyaromatic hydrocarbons by its similarity to benzene beyond the scope of simple Hückel theory on which it was originally based. The reported generalization allows the new index to be calculated at a realistic contemporary ab initio level of theory, opening the possibility of its use as a new measure of aromaticity. As will be shown, the new index correlates very well not only with the original Polansky index but also with the Generalized Population Analysis based multicenter index

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
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
