Schumpeter meeting Keynes: A policy-friendly model of endogenous growth and business cycles
Get PDFThis paper studies an agent-based model that bridges Keynesian theories of demandgeneration and Schumpeterian theories of technology-fueled economic growth. We employ the model to investigate the properties of macroeconomic dynamics and the impact of public polices on supply, demand and the fundamentals of the economy. We find that the complementarities between factors influencing aggregate demand and drivers of technological change affect both short-run fluctuations and long-term growth patterns. From a normative point of view, simulations show a corresponding complementarity between Keynesian and Schumpeterian policies in sustaining long-run growth paths characterized by mild fluctuations and acceptable unemployment levels. The matching or mismatching between innovative exploration of new technologies and the conditions of demand generation appear to suggest the presence of two distinct regimes of growth (or absence thereof) characterized by different short-run fluctuations and unemployment levels
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
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
Un atelier alternativo a quello di Carlo Fontana: la scuola del "misterioso" Abraham Paris
No full textIgnorato e univocamente considerato dalla storiografia contemporanea come “misterioso signor
Abrahamo”, per la frequente presenza di questo nome su diversi disegni di Nicodemus
Tessin (1654-1728), Johann Bernhard Fischer von Erlach (1656-1723) e James Gibbs (1682-
1754), la personalità dell’architetto Abraham Paris (1641c.-1716) risulta solo di recente indagata
nelle opere e nelle vicende biografiche. Ma se nella ricostruzione della sua attività
professionale permangono ancora lati oscuri, viceversa la sua vocazione per la didattica è stata
messa in luce da recenti studi di Borje Magnusson ed Elisabeth Kieven, i quali hanno ipotizzato
l’esistenza di una scuola privata d’architettura tenuta a Roma dallo stesso Paris nel corso
dell’ultimo quarto del XVII secolo, che ha annoverato tra le sue fila diversi giovani architetti
italiani e stranieri
L'architetto e le collaborazioni letterarie: Carlo Fontana, Francesco posterla e Carlo Vespignani
No full textIl saggio, che propone nuove riflessioni critiche intorno all’attività letteraria diCarlo Fontana
(1638-1714), analizza il complesso rapporto che l’architetto instaura con il poeta Francesco
Posterla e con il monsignore Giovanni Carlo Vespignani. In particolare, sulla base di una
nuova documentazione archivistica, si esamina come, in maniera vicendevole, i tre personaggi
si alternano tra loro nel ruolo di ispiratore, esecutore e finanziatore di alcune opere pubblicate
a Roma nell’ultimo scorcio del Seicento
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
