INCERTEZZE SULLA NOZIONE DI CONTROLLO PUBBLICO
No full textIl contributo mostra l’evoluzione della giurisprudenza contabile circa la perimetrazione della nozione di
“controllo pubblico”, in relazione alle società partecipate, alla luce del dettato dell’art. 2, comma 1,
lett. b) e m), del testo unico. Ci si interroga, in particolare, se sia da applicarsi la disciplina pubblicistica
restrittiva per le società a controllo pubblico ogni qual volta sussista la titolarità pubblica cumulativa da
parte di una pluralità di pubbliche amministrazioni della maggioranza del capitale sociale o se, al
contrario, occorra condurre una valutazione sulla capacità, in concreto, di incidere sulle decisioni
finanziarie e gestionali strategiche relative all’attività sociale
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
A Model-Driven Approach for the Formal Verification of Storm-Based Streaming Applications
No full textData-intensive applications (DIAs) based on so-called Big Data technologies are nowadays a common solution adopted by IT companies to face their growing computational needs. The need for highly reliable applications able to handle huge amounts of data and the availability of infrastructures for distributed computing rapidly led industries to develop frameworks for streaming and big-data processing, like Apache Storm and Spark. The definition of methodologies and principles for good software design is, therefore, fundamental to support the development of DIAs. This paper presents an approach for non-functional analysis of DIAs through D-VerT, a tool for the architectural assessment of Storm applications. The verification is based on a translation of Storm topologies into the CLTLoc metric temporal logic. It allows the designer of a Storm application to check for the existence of components that cannot process their workload in a timely manner, typically due to an incorrect design of the topology
Trace checking of streaming applications through DICE-TraCT
No full textThis paper introduces DICE-TraCT, the tool—part of the DICE toolchain—that allows developers of Data Intensive Applications to analyze traces of executions of such applications and detect deviations from the expected behavior. The tool works in tandem with the companion formal verification tool D-VerT, to check that the parameters used for the sizing of applications and that guarantee the desired safety and timing properties are indeed correct
Remediation management of contaminated sites using geostatistical methods
No full textThe present paper deals with the management of contaminated sites remediation and, within this wide subject, it addresses two particular aspects: a) the definition of the areas to be cleaned up and b) for each area, the assessment of the minimum quantity of soil to be treated or removed to reach predetermined target quality goals.
Objective of the work is to set up a numerical procedure, based on geostatistical methods, suited to solve the mentioned problems. These arise in a remediation process when, following the characterization phase and the selection of the remediation technology, it is necessary to perform the quantitative assessment of the contamination required to draw the final project and to estimate relevant costs.
The procedure has been applied to a polluted site in northern Italy where, for several decades, different chemical activities have been based. The site has recently been investigated and characterized. The illustrated application is to be considered just as an experimental support to identify and finalize the procedure
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
