IRAS 22036+5306: an Al2O3 oxide-dominated post-AGB star
Get PDFRadiative transfer modelling of the Infrared Space Observatory (ISO) spectrum of IRAS 22036+5306 has shown that its unusual 11-μm band can be suitably modelled with an alumina-olivine mixture substantially dominated by the former. The results of this wo
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
Demystifying Sraffa’s Theory of Value in the Light of Arrow and Debreu
Get PDFThis paper compares the models of Arrow and Debreu [1954] and Sraffa [1960], and concludes that (1) the models are informationally distinct conceptions of a capitalist economy, (2) they support radically distinct – though complete and entirely correct – theories of value, (3) the prices in the two theories are different both in terms of definitions and values, (4) in Sraffa‘s model it is impossible to define constant returns to scale, while in Arrow-Debreu this property is admissible, and (5) in Arrow-Debreu the interpersonal income distribution is determined whereas in Srafa‘s model the distribution of income between workers and capitalists is undetermined.constant returns to scale, theory of value, relations of production, counterfactual information, prices, exchange values, income distribution, general equilibrium, capital, marginal product
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
Appropriate 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
On two theories of value and distribution
Get PDFThis paper compares the theory of value and distribution of Arrow and Debreu [1954] with that of Sraffa [1960]. I consider such versions of the two models that capture their salient features, without aiming at the greatest possible generality, so as to isolate the precise nature of the differences between the two conceptions of the same economic reality, and inter alia, to quarantine both the sources and the entailments of the differences in the two theories that respectively purport to determine the values of commodities and distribution of income in society. Both theories are complete and consistent. Sraffa’s model is based exclusively on factual information, so it achieves less in terms of determining endogenous variables. The Arrow-Debreu is based on counterfactual information regarding additional production scenarios that are unobserved, in addition to the factual information that Sraffa has, so it achieves more by way of determination of endogenous variables. In terms of entailments, in Sraffa's theory there is an insufficiency of determinants in the economic grounds of society, thereby requiring the political component of society to also play an influential role in the joint determination of values and distribution. In the Arrow-Debreu model this determination is made complete solely in the economic sphere of society, rendering this theory purely economic, rather than political-economic, as in Sraffa. Both the information content difference at source, and the purely-economic versus political-economic difference in the entailments of what it takes to determine values and distribution, render the two theories radically different. In addition, (1) the prices in the two theories are different both in terms of definitions and values, and (2) since Sraffa’s model has only one set of numbers on the observed production of commodities by means of commodities and labor for a single year, it is impossible to define constant returns to scale, while in the Arrow-Debreu model, this property is admissible, and possible to define, because their model’s information base is sufficiently larger than Sraffa’s. Further, Sraffa’s theory is invariant to (a) the interpretation of prices – market-clearing, long-period, or whatever, (b) multiplicity of profit rates across industries, instead of a uniform rate of profit, and (c) presence or absence of general aggregate demand functions for commodities, and is (d) more general than the Arrow-Debreu theory because it is based on weaker assumptions, in the sense of a strictly smaller information set, so that it is only to be expected that the Arrow-Debreu theory would be capable of determining more endogenous variables in the model of an economy.
