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

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
Bivariate semi-Markov reward chain and credit spreads
No full textIn this paper, a bivariate semi-Markov reward chain (BVSMC) model is presented. Equations for the higher order moments of the reward process are presented for the first time and applied to the problem of modelling the credit spread evolution of an obligor by considering the dynamic of its own credit rating and that of a dependent obligor called the counterpart. The paper shows how to compute the expected value of the accumulated credit spread (expressed in basis points) that the obligor should expect to pay in addition to the risk free interest rate. Higher order moments of the accumulated credit spread process convey important financial information in terms of variance, skewness and kurtosis of the total basis points the obligor should with pay in a given time horizon. The paper contributes to the literature by extending on previous results on the semi-Markov reward chains, BVSMC and credit spread modelling by providing unifying approach to these problems. The model and the validity of the results are illustrated through a numerical example
Integrating migrants in Europe: the EU’ s ‘viewpoint’ from a legal perspective
No full textThe main aim of the study is to investigate the concept of evaluation
applied to a corpus of legislative instruments in favour of migrants’
rights.
In particular, attention has been paid to some evaluative lexical
choices found in association with two key-words – integration and protection.
More specifically, evaluation has been investigated taking into
account the phrases and the grammar patterns most frequently found
with these words in the corpus.
The corpus includes some EU Directives in the time span 2001-
2013 aimed at integrating migrants (see Appendix A). The Directives
include rights such as family reunification, equal opportunities to men
and women, international protection, the conditions of entry and residence
of third-country nationals for the purposes of highly qualified employment,
granting and withdrawing international protection. In short,
all the Directives are aimed at integrating migrants, granting them some
rights and promoting common procedures among the Member States in
order to better protect them
