Using Trees to Investigate Structural Breaks
No full textNel presente lavoro viene proposto un approccio per la individuazione di break strutturali in serie temporali quando si dispone di serie esplicative. Il metodo si articola in uno schema iterativo basato sull'uso alternato della analisi canonica e della regressione ad albero. In particolare la informazione contenuta nelle serie esplicative viene sintetizzata mezzo della analisi canonica in combinazioni lineari successivamente usate come covariate nella regressione ad albero. la proposta viene illustrata mediante uno studio di simulazion

Dating multiple structural breaks in the US Ex-Post Real Interest Rate
No full textIn this paper we propose a non parametric approach for detecting
multiple structural break occurring at unknown dates. The method
exploits, in the framework of least squares regression trees, the
contiguity property introduced by Fisher for grouping a single
real variable. The proposed approach called ART is applied to the structural
breaks analysis of the U.S. Ex-Post Real Interest Rate series

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
