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
Le due crisi: crisi del capitalismo e crisi ambientale. Una soluzione sostenibile? (parte II)
No full textVista nella Parte I la gravità della crisi ambientale, soprattutto l’instabilità
climatica che caratterizzerà le prossime decadi, nella parte II si esplicitano le
ragioni profonde della necessità di cambiare, e come, il modello di sviluppo.
Negli ultimi quarant’anni la crisi ecologica non è mai diventata una variabile
importante nelle politiche economiche. Colpa del neo-liberismo imperante,
dall’ “unilateralismo” dell’amministrazione USA al “fiscal compact” della
UE? Sì, ma anche le altre scuole economiche commettono lo stesso errore.
L’attuale crisi del capitalismo è una crisi di sovrapproduzione, il cui carattere
quantitativo, dovuto all’innovazione tecnologica nel mercato globalizzato,
rende insuperabile la contraddizione tra l’aumento dell’offerta e la capacità
del mercato di assorbire la domanda: quale colossale redistribuzione del reddito
sarebbe necessaria per adeguare la “spendibilità” all’offerta? Né la deterrenza
nucleare consente, come nelle due analoghe grandi crisi precedenti,
il “ricorso” alla guerra mondiale. Che fare? La sostanziale sordità dell’Economia
alla questione ambientale stimola gli autori, da un lato a proporre gli
elementi teorici per un “ciclo” economico che coniughi variabili economiche
ed ecologiche in un modello di “stato stazionario”; dall’altro a vedere la
stessa crisi ecologica come una straordinaria opportunità per cambiare da
subito il modello verso un’economia sostenibile, attraverso la rivoluzione
energetica, la green economy e il terzo mercato.In Part I the ecological crisis has been highlighted, mainly the climate
instability that will last for next decades; in Part II are given the reasons
why to modify, and in which manner, the current development model. In the
last forty years the crisis of environment has never become a variable to be
considered in programming economic policies. Sin of the dominant neo-liberalism,
from the “unilateralism” of the US administration up to the “fiscal
compact” by EU? Sure, but also the other economic schools meet the same
error. The present crisis of capitalism is an overproduction crisis, whose
peculiar quantitative character, due to the technological innovation in the
globalized market, makes insuperable the contradiction between the increment
of the offer and the capability of the market of absorbing the demand:
which gigantic redistribution of income should be done in order that the
“spendability” can match the offer? Neither is possible, like in the two previous
great crises, the “recourse” to a world war as a solution of the problem;
the nuclear deterrence denies it. What to do? The essential deafness
of Economy to the environmental issue pushes the authors, on one hand,
to propose some theoretical elements for an economic cycle that conjugate
ecological variables to economic ones in a “stationary state” model; on
the other hand, to look at the ecological crisis as an extraordinary chance
for changing, from now, the model of development towards a sustainable
economy, by means of the “energy revolution”, the green economy and the
“third market”
The chariots of Pharaoh at the Red Sea The crises of capitalism and of environment. A modest proposal towards sustainability
No full textThe present global situation recalls us the two walls in which the Red Sea had split to allow that Pharaoh follow the people beloved by God. On one wall stays the economic crisis, that is tout court the capitalist crisis, on the other wall there is the predicament of environment. Then, it is reasonable to wonder if the walls will tumble down with severe damages to all the characters, this time, of this representation; unless a “modest proposal”, of the kind that we will try to formulate in this paper, be intensively pursued. Several of the themes here gathered have already been object of reflection in some previous works. In this paper we collect and enrich those ideas, and put a special attention to the so called economic “cycle” and a stationary ecological-economic model in a sustainability scenario. Some years ago, the financial “bubble”, burst with its destructive and lasting economic and social consequences, the bloody geopolitics of oil of the last decades, one sixth of the humankind under the threshold of surviving, the plunder of the resources of the Earth – from the rare ores up to the great pluvial forests –, the general environment crisis, dramatic for the climate change, exemplified in an also too much persuasive way that capitalist democracies as well as totalitarian States, those which have chosen the free market economy, were not able to face the two crises of our title.INGLES
