A multi-stakeholder analysis of the economic efficiency of industrial energy efficiency policies: Empirical evidence from ten years of the Italian White Certificate Scheme
No full textThere is growing interest worldwide in more effective policies to promote industrial energy efficiency and mitigate climate change. The White Certificates Scheme is a market-based mechanism aimed at stimulating the adoption of Energy Efficiency Measures. The Italian White Certificates scheme - one of the most long-standing and articulated - is a successful example of industrial energy efficiency policies, considered an interesting and remarkable case by other countries, especially due to its robustness in terms of the volume of certificates traded. Despite the considerable interest in White Certificates, an in-depth analysis of the economic efficiency of the mechanism from the perspective of different stakeholders is still lacking. To address this gap, this study develops a cost-benefit evaluation framework and a multi-stakeholder economic efficiency analysis of the Italian White Certificates scheme focusing on the Italian State, utilities, players in the energy efficiency value chain, and energy users. Our findings (also corroborated with sensitivity analyses) show that the White Certificates Scheme has led to several positive impacts for almost all stakeholders involved, with the exception of energy utilities that have suffered a major economic loss mainly due to a reduction of energy sold to end users. Such loss is likely to promote a deep change in the role of utilities in the energy market in terms of the services they offer and their business models. Our findings, in addition to providing useful directions for future research, offer interesting insights and implications for policymakers who may take inspiration from the pros and cons of the Italian White Certificates scheme when promoting energy efficiency through incentive mechanisms
Considerazioni su alcuni vetri medievali e di prima età moderna rinvenuti nello scavo della Cattedrale di S. Maria a Savona,
No full textIllustrazione di un gruppo di vetri di XIV e di XVI secolo portati alla luce nello scavo della Cattedrale medievale di Savona: bottiglie, bicchieri, lampade.During the 2007-2010 excavations of St. Mary’s Cathedral (historic fortress of Priamàr - Savona) carried out by the International Institute of Ligurian Studies, a variety of glass specimens were recovered. Some were remarkable for their quality
and degree of conservation. A first group of those specimens, located on top of a 14th century masonry burial, comes from
the south side of the cloister. A second group, part of the tableware set of the Commissioner, belongs to the 16-17th centuries.
Their composition was assessed by non-invasive X-ray microfluorescence and compared to known data, to tentatively
determine glass compositions indigenous to Savona and Altare, not yet identified in the litterature
A characterisation framework of energy services offered by energy service companies
No full textEnergy Service Companies (ESCOs) are key players in the provision of energy services, hence they are considered strategic means to foster energy efficiency across countries. Nonetheless, despite the undergoing radical trans-formation within the ESCOs industry -especially the increasing tendency to bundle services, recent research capable to capture such evolution and development, in terms of services, technologies, and markets targeted by ESCOs is scarce. The present study aims at fulfilling the outlined research gaps by developing a novel framework for the classification and characterisation of services offered by ESCOs, as well as technologies and markets addressed. Services are characterised into nine categories, namely: preliminary analysis; project assessment; project contracting; project financing; project technology management and project supervision; energy pro-curement, management of incentives and regulations, and other services. The developed framework is then preliminary tested by applying it to a sample of eight Italian ESCOs to assess its completeness and usefulness. Results show the capability of the framework to adequately detail and map clusters of services-technologies -markets addressed by ESCOs, also identifying areas for future business opportunities for ESCOs themselves. The study concludes with recommendations for industry and policymaking on future efforts to promote energy services, as well as future research in this area
L’attestazione della formazione del silenzio assenso: tra “certezze pubbliche” e incertezze applicative
No full textThe author offers a study on the certification of tacit consent formation, as provided for by Article
20, paragraph 2-bis, Law No. 241/1990, analyzing its framing as an instrument for the production
of public certainty. In a context of uncertainties that characterize tacit consent, the legal instrument
under this research risks raising further uncertainties and requires a systematization that allows
for the verification of its real utility. Issues such as the relationship with the various administrative
powers, both first and second instance, with which the certification of tacit consent interacts are
analyzed. Finally, the critical points and interpretative solutions underlying the private selfdeclaration
that, after ten days from the applicant's request, "replaces" the certification are
examined, in order to develop conclusive and reconstructive considerations of the examined legal
instrument
Riflessioni sul problema della trasmissibilità dell’interesse legittimo: profili ricostruttivi e prospettive di analisi
No full textL’autore offre uno studio sul problema della trasmissibilità dell’interesse legittimo, rilevando come
sul tema si siano registrate differenti e contrapposte soluzioni, tanto in dottrina quanto in giurisprudenza,
prevalentemente dovute alle diverse rappresentazioni della situazione giuridica soggettiva. Oltre a evidenziare i
riflessi procedimentali e processuali della vicenda circolatoria, il tentativo dello studio è di proporre possibili
alternative ricostruttive del problema della trasferibilità dell’interesse legittimo, facendo leva sia sul dato normativo
che sui caratteri strutturali della figura.The author offers a study on the problem of the transmissibility of legitimate interest, noting that,
both in doctrine and in jurisprudence, there are different and conflicting solutions on the topic, mainly due to the
different representations of the subjective legal situation. The study's attempt is, on one hand, to highlight the
implications that the transfer of legitimate interest could have on the proceeding and the trial and, on the other
hand, to propose possible reconstructive alternatives to the problem of the transferability of legitimate interest,
considering both the normative data and the structural features of the figur
Preface - YOCOCU 2012, an Efficient Collision
No full textIn chemistry for a collision to be efficient, i.e. breaking atomic bonds allowing the formation of new molecules
and compounds, the reagents have to collide with an energy that is proportional to the bond strength and a
direction that depends on the molecular geometry. This is what happened during YOCOCU 2012 (YOuth in
COnservation of CUltural heritage), that took place at the Hof van Liere in Antwerp, Belgium on 18-20 June
2012
Iron speciation in soda-lime-silica glass: a comparison of XANES and UV-vis-NIR spectroscopy
No full textScientific analyses of ancient glasses have been carried out for many years using elemental chemical analysis. However, it is known that the control of the redox conditions in the glass melt has a strong implication on the final hue of glass because it affects Fe2+/ΣFe. Therefore an increasing number of studies on the redox conditions have been published in recent years by means of synchrotron based X-ray absorption spectroscopy. This is a technique which is not easily accessible and requires dedicated facilities. In this paper we describe an alternative approach by means of optical absorption spectroscopy. We synthesised 10 soda-lime-silica glasses with known redox conditions and iron concentration to calibrate the absorption at 1100 nm as a function of Fe2+ concentration. The linear extinction coefficient was also determined. These glasses were also studied by means of X-ray Absorption Near Edge Structure (XANES) spectroscopy. Electron paramagnetic resonance spectroscopy was additionally used as an ancillary method to verify the quality of our data. Furthermore 28 samples from real archaeological samples were analysed by XANES and optical spectroscopy as a case study. The Fe2+/ΣFe values obtained were compared and demonstrated that the two techniques were in good agreement with each other. Optical spectroscopy can be applied in situ with moderate sample preparation to determine the concentration of Fe2+. To investigate the redox conditions, especially as a first screening approach, this methodology is an important tool to take into consideration before applying more sophisticated techniques such as XANES, which is more elaborate and requires high-tech resources
Effectiveness of modified atmosphere and vacuum packaging in preserving the volatilome of Stelvio PDO cheese over time
No full text: We aimed to assay the effectiveness of vacuum or modified atmosphere packaging in preserving the organoleptic characteristics of already ripened slices of Stelvio Protected Designation of Origin cheese during 3 months of storage. A multi-omics panel, including metagenomic and metabolomic analyses, was implemented together with physicochemical and sensory analyses. Among the 177 volatiles identified, 30 out of the 50 potent odorants were found to be prevalent, regardless of packaging. Isovaleric acid showed the highest relative intensity in all samples. Caproic and caprylic acids always increased during storage, while metabolites such as dodecane and 2,3-butanediol always decreased. Slow proteolysis occurred during storage, but did not differentiate cheese samples. The type of packaging differentiated the microbiota and volatile profile, with modified atmosphere packaging keeping the volatilome more stable. Out of the 50 potent odorants, 9 were relevant to sample discrimination, with 8-nonen-2-one, 2-nonanone, and caproic acid being more abundant in stored samples
