Un’indagine complicata, da spiegare bene. La storia, i presupposti e alcune proposte per i seguiti dell’indagine conoscitiva di ARERA sul trattenimento di capacità nel mercato elettrico del giorno prima nel biennio 2023-2024
No full textQuesto lavoro presenta e discute una recente Indagine conoscitiva condotta
dall’Autorità di Regolazione per Energia Reti e Ambiente (ARERA) sul funzionamento del
Mercato del Giorno Prima, che ha messo in luce potenziali comportamenti strategici dei
produttori di energia elettrica, volti a trattenere capacità produttiva per alzare i prezzi
di mercato. Questa analisi è svolta descrivendo dapprima il framework economico che
caratterizza i mercati all’ingrosso dell’energia ed in seguito il quadro giuridico relativo al
Regolamento (UE) 1227/2011 concernente l’integrità e la trasparenza del mercato dell’energia all’ingrosso (REMIT). Il lavoro si arricchisce altresì di un confronto con casi simili che si sono sviluppati in altri paesi europei (Francia, Inghilterra, Spagna e Germania)
e chiude con una valutazione sulle possibili conseguenze dell’indagine, a seguito delle
valutazioni caso per caso previste dal regolamento REMIT attualmente in corso, e con
alcune considerazioni circa il funzionamento del market monitoring in questi mercati
Changing the regulation for regulating the change. Innovation-driven regulatory developments in Italy: smart grids, smart metering and e-mobility
No full textFor a long time considered as technologically mature, electric systems are now facing a period of rapid evolution, inspired by climate change concerns. Several studies show that current regulation of natural monopolies does not offer sufficient incentives for network operators (and network users) to participate in this process.
Taking Italy as a case study, this paper analyses how energy regulation can change to support the current transformation. We describe the recent regulatory interventions in the domain of smart grids, smart metering and electromobility, with a specific emphasis on the provisions aimed at fostering innovation - an issue that until recently has received almost no attention in the literature nor in the practice of regulation.
The progress we observe is considerable in all new areas of concern, and, above all, in the regulator's commitment to provide the right incentives for investments in demonstration projects: the acquisition of experience is regarded as essential to move to more sophisticated regulatory instruments. Finally, regulation is also increasingly concerned with network users, both traditional and new, with the objective to stimulate more active behaviors
The Role of Information Systems to Support Performance Management in Public Administration: The Case of the Italian Regulatory Authority for the Energy SectorInformation Systems, Management, Organization and Control
No full textThe objective of this paper is to offer a significant contribution to the debate on how to implement performance measurement systems in the Public Administration by proposing a model based on an integrated information system where planning (strategic and operational) and measurement systems are supported by a single application that drives the whole process. The research is based on the case study method [1] and analyses the characteristics of ICT systems in supporting the management control systems developed by the Italian regulatory authority for the energy sector (AEEG). The results of our work suggest that a single measurement metric may be identified for the assessment of the output produced by both core and accessory structures, in complete integration with the planning and control process
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
