Economic Insecurity in the Italian Macro-Regions
Full text linkThe interest for economic insecurity has grown constantly over the last decade due to the shock of the latest global crisis that has involved the wealth and behavior of households thus attracting the attention of many authors in contemporary literature. Furthermore, the concept of economic insecurity may be linked to the concept of economic inequality, since an increase in economic inequality may be connected to insecurity and vice versa. The aim of this article is to measure economic insecurity from 2012 to 2016 in Italy both at national and sub national level. The methodology applied refers to the economic insecurity index suggested by Bossert et al. (2019) and the data considered are taken from the Survey on Households Income and Wealth carried out by the Bank of Italy. Moreover, this work aims to investigate the possible link between economic insecurity and economic inequalities, measured through the share of wealth owned by the richest 5% of the population. The main findings show a relevant general increase of economic insecurity in the period between 2012 and 2014, and interesting differences in the variation of economic insecurity at sub national level. Insecurity appears closely linked to the level of inequality and the trend of inequality in the previous period
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
The Measurement of Economic Security through Relative Indicators
No full textEconomic Security is a topic which focused the attention of many researchers in the past years. With the COVID-19 pandemic, interest has grown drastically because economic security influences the lives of many individuals and consequently the government’s economic and political choices. In this framework the individual insecurity indicator proposed by Bossert and D’Ambrosio [1] it’s a landmark, because of its useful analytical properties. We embrace their notion of economic insecurity and we propose relative security indicators starting by the absolute one they suggested. We compare the indicators in terms of analytical
properties and in terms of applicability to European countries using the EU-SILC
(2019) data-set

Design of couplers for traveling wave RF structures using 3D electromagnetic codes in the frequency domain
No full textIn this paper, a simple equivalent circuit model of a traveling wave RF structure with input and output couplers is introduced. A few properties related to evaluating the reflection coefficient of the single coupler are then obtained and discussed. From these properties, a general procedure to design couplers for traveling wave structures using 3D electromagnetic codes in the frequency domain is derived. Finally, an example of coupler design for a 2 pi/3 X band accelerating structure is illustrated. (C) 2007 Elsevier B.V. All rights reserved
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
