La riforma costituzionale. I riflessi sull'ordinamento della finanza pubblica
No full textAn important reform of the Italian Constitution, has been approved by Parliament in April 2016 and will be submitted to a referendum in Autumn 2016. This paper examines its consequences on the procedures for approval of the budget and of expenditure bills and on intergovernmental financial relations. The abandonment of a perfect bicameral system will give to the lower house a clear prevalence in the approval of laws including the budget. This will bring Italy more in line with the international experience. The Senate however will maintain equal legislative power in a series of matters. The capacity of playing its role effectively will depend on the implementation of the reform. In particular the actual mode of selection of senators by regional councils needs to be clarified. The reform also reshapes the relations between State and Regions, in favor of the central State. Particularly important is the shifting of co-ordination of public finance and the taxation system from the matters attributed to concurrent legislation to those for which the State has exclusive legislative powers. The most serious limit of this part of the reform, however, is the virtual exclusion of the five Regions that have special forms of autonomy
Licenziamenti definitivi o temporanei? Durata della disoccupazione nelle liste di mobilità tra nuovi e vecchi datori di lavoro
No full textThe «mobility lists» programme, mainly designed to support the income of workers in the event of collective redundancies, contains also important incentives to re-employment. The paper investigates the duration of unemployment in the lists using longitudinal data (unemployed workers enrolled in the lists for region Umbria between 1995 and 1998). Our data set differs from those used in previous research as it allows to identify 1) spells of fixed term employment during permanence in the lists 2) whether exit toward employment occurs as a recall from the previous employer or as a new job. Estimation of a competing risk model shows a strong negative duration dependence only for the recall hazard, while new jobs exhibit no duration dependence. The features of the process governing the recall hazard suggest the possibility of opportunistic behaviour by firms, with important implications for the design of the scheme
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
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
