Italian Municipalities and the Management of Covid-19 Emergency: a Kaleidoscope Effect
No full textCrises like Covid-19 represent a test for the government capacity of manage uncertainty. Unlike other crises, Covid-19 has tested this capacity by requiring the simultaneous activation of all levels of government. In a fragmented system such as the Italian one, a relevant obstacle has been represented by the different level of cognition among the actors involved, that is the capacity to recognize the degree of emerging risk to which a community is exposed and to act on that information. Although the redundancy of the Italian local government cannot be considered as an explicit strategy, it has resulted in enhanced capacities associated with system resiliency. Fragmentation and heterogeneity in leadership styles at the local level have certainly absorbed part of the crisis management capacity, but at the same time they have created, with significant exceptions, margins of flexibility and adaptation of public action, by also activating synergies and collaborations with other local actors. The Italian experience facing Covid-19 confirm that in crisis management that there is no optimal formula for harmonizing competing interests and tensions or for overcoming uncertainty and ambiguous government structures
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
Software Trigger Systems in High Energy Physics
Full text linkIn order to efficiently collect and store experimental data, the High Energy Physics experiments need a trigger system to separate --- in real-time --- interesting experimental events (signal) from uninteresting ones (background).
In the aim of optimising the performance, a modern trigger system splits the data selection task in two or more stages, where the highest level one is usually implemented as a great deal of software processes (software trigger) running in parallel on the nodes of a computer farm which can reach the size of 2000-5000 PCs.
Data link technologies and operating environment used in the most challenging High Level Triggers of the recent High Energy Physics experiments are here reviewed. In particular, the High Level Trigger of the LHCb experiment at CERN, which has the highest input event rate (1.1 MHz) among the forthcoming experiments, is taken as an example
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
Francia
No full textLa Francia ha una tradizione amministrativa basata su una forma di Stato molto centralizzato. Per molto tempo non si è messo mano alla legislazione e all’organizzazione dei servizi pubblici: la Loi Organique relative aux Lois de Finances del 2001 ha sostituito una legge risalente al lontano 1959 e rimasta in vigore per più di quarant’anni. In realtà, però, dal 1989 la Francia ha iniziato un percorso di riforme che l’ha portata a rinnovare completamente e riposizionare su nuovi paradigmi l’organizzazione dei propri servizi pubblici. Il capitolo illustra il percorso di progressiva diffusione del performance management nell'amministrazione centrale francese
