La tutela del patrimonio archeologico in acque profonde
No full textAt great depths, on the seabed of the Mediterranean Sea, there is an immense submerged archaeological heritage to be
discovered, studied and protected. Protected from the waters for over 2000 years, today it risks being destroyed forever
by the impact of trawling. Extensive fishing damage is often documented by sonar and multi-beam side-scan investigations
and, today, new instruments as ROV allow very deep investigations on numerous shipwrecks. The depth at which they are
located does not guarantee their protection. In fact, almost all the wrecks explored have a common trait: they are at risk
of disappearing due to the serious damage caused by the passage of trawling nets. In the central-northern part of the
Tyrrhenian Sea and the Ligurian Sea, there are over 40 deep wrecks identified, since 2002, by Guido Gay of the Fondazione
Azionemare and thanks to its discovery, the Capitaneria di Porto of La Spezia in Liguria and PortoTorres in Sardegna,
were able to create some forbidden area to the trawling boat 0,6 miles around the site. A satellite surveillance system in
the Coast Guard control room ensures that the rules are enforced. For the first time in Italy an effective system for the
protection of the submerged archaeological heritage has been created, an example of what should be done for all reported
wrecks. However, there are still many wrecks at the mercy of fishing activities that risk being destroyed

The Determinants of Forward-Looking Information in Integrated Reporting: An Empirical Investigation in Europe
No full textThe aim of this paper is to investigate the effect of firm characteristics on forward-looking disclosure (FLI) within the context of Integrated Reporting (IR).
The study assesses the extent of FLI provided in Integrated Reports of European organizations and empirically fills the research gap into the topics of FLI disclosed in the IR. A manual content analysis is run to investigate the level and the topics of FLI in 132 Integrated Reports available in the International Integrated Reporting Council web site. A disclosure index composition consisting of 27 information items is developed from the list of content elements comprised in the Integrated Reporting Framework (IIRC, 2013). Three hypotheses are proposed and eight Models are tested within a multivariate regression analysis in order to explore the effects of three main variables (firm size, profitability and leverage) on FLI. The study confirms that firms are reluctant to provide FLI in Integrated Reports. The results show that profitability and firm size have a statistically significant relationship with the level of specific topics of FLI. Conversely, leverage is found to be insignificant in explaining the extent of FLI. The results provide comprehensive insights into the current forward-looking disclosure practices of early adopters in Integrated Reports. The research adds to the prior disclosure literature concerning FLI since acquired results are ambiguous. There are a very restricted number of studies that have explained the variation of FLI in the light of firm characteristics and no study has analyzed this research topic within the context of IR
I drammi wagneriani nell’esperienza politica e intellettuale di Guido Manacorda
No full textNel quadro delle traduzioni italiane delle opere di Richard Wagner, un posto di rilievo merita certamente il lavoro di Guido Manacorda. Il contributo si occuperà di questo personaggio controverso della politica italiana degli anni ’30 che dedicò un lungo studio al compositore tedesco destinato a confluire nell’opera in undici volumi, I drammi, composti dall’edizione tedesca con traduzione italiana e commento critico, edita tra il 1920 e il 1936. La pubblicazione del lavoro wagneriano di Manacorda corrispose agli anni più intensi della sua attività politica che lo vide in costante equilibrio tra nazionalsocialismo, fascismo e cattolicesimo. A questa difficile situazione politico-ideologica fece da sfondo l’opera di traduzione di Wagner, che Manacorda, nonostante i crescenti impegni politici, non abbandonò mai. Scopo della relazione, dunque, sarà quello di inquadrare il lungo lavoro wagneriano del germanista nel convulso contesto politico di allora, per cercare di gettare luce sulla vicenda di un intellettuale ancora avvolta nell’ombra
Women on Board and ESG Performance: Insights from the Italian Utilities Sector
No full textThe purpose of this paper is to investigate the relationship between gender diversity and environmental, social and governance (ESG) performance in the Italian utilities sector. The study examines whether the presence of women on the board of directors (BoD) is related to ESG dimensions. We analyzed a sample of 482 utility companies for the period 2018-2022 and we developed an econometric model applying unbalanced panel regression data with firm fixed effects and controls per year. Within a multivariate regression model, the authors considered the ESG score provided by Refinitiv Eikon to test the research hypotheses. Findings show that the presence of women on board of directors improves ESG performance when a critical mass of female board members (at least three) is reached. A critical threshold of female directors also positively influences the scoring of environmental and social pillars. From a managerial perspective this study draws attention to BoD composition encouraging utility companies to define internal corporate governance mechanisms thoroughly. The overall findings support managers, policy makers and regulators on how to improve ESG performance through gender diversity on BoD. This paper offers an in-depth examination of the ESG practices of utility firms, and it attempts to bridge the gap in prior literature on the determinants of ESG performance in the Italian utilities sector. This study is the first that investigates the relationship between board gender diversity and ESG performance in such a context exploring how a critical mass of women on BoD affects ESG dimensions
Board gender equality and ESG performance. Evidence from European banking sector
No full textPurpose – The purpose of this paper is to investigate the relationship between board gender equality and environmental, social and governance (ESG) performance in the European banking sector. The study examines whether and how the presence of women on the board of directors (BoD) influences ESG dimensions. Design/methodology/approach – The authors analyzed a sample of 72 European Union banks for the period 2015–2021 and developed an econometric model applying unbalanced panel data regression with firm fixed effects and controls per year. To test the research hypotheses, the authors considered gender equality in terms of female participation on the BoD and measured ESG dimensions by using the ESGscore provided by Refinitiv. Findings – The findings suggest a significant positive relationship between the number of women on BoD and the ESG performance of European banks only up to a certain threshold of female directors (at least three women). The study also explores how the proportion of women on BoD influences the individual ESG pillars. The results show that the percentage of female directors has a positive and statistically significant impact on the social dimension of the ESG framework. Research limitations/implications – The investigation is highly relevant to investors considering ESG issues in their decision-making process. The overall findings support policymakers and regulators on how to improve ESG performance through the design and the application of corporate governance (CG) mechanisms. From a managerial perspective, the study suggests that managers and CEOs should focus their efforts on establishing the right gender combination of directors on bank BoDs. Originality/value – This paper offers an in-depth examination of the CG practices of banks, and it attempts to bridge the gap in prior literature on the determinants of ESG issues in the European banking industry. To the best of the authors’ knowledge, this study is the first that investigates the relationship between the representation of women on BoDs and the ESG dimensions measured by the Refinitiv Eikon score. The use of critical mass theory adds a fresh perspective to the literature on ESG in Europe since the influence of board gender diversity on ESG performance of the European banks is still unaccounted for. This study addresses this pressing research issue drawing on resource dependence, agency and legitimacy theories
The effects of economic policy uncertainty on hotel performance.Evidence from the Italian hospitality sector
No full textPurpose - This study aims to investigate the effects of economic policy uncertainty (EPU) on Italian hospitality sector. The investigation attempts to explain whether hotel performance drops when the perceived economic uncertainty increases in the period 2018-2022.
Design/methodology/approach - The study examines the impact of EPU on hotel performance in a sample of 661 Italian luxury hotels. To establish the relationship between EPU and hotel performance, we employ the generalized estimating equations (GEE) technique on 3,305 hotel-year observations.
Findings - The results show that EPU has a negative impact on hotel performance. More specifically, the analysis reveals that EPU is negatively and significantly related to the revenue per available room (REVPAR), average daily rate (ADR) and hotel occupancy (OCCR). We also look at the role of hotel brand chain affiliation and the moderating effect of conference space and hotel wellness services on the relationship between EPU and hotel performance.
Research limitations/implications - Results provide new evidence for academics to critically evaluate the behavior of luxury hotels under uncertain economic conditions. The investigation offers valuable information also for government, tourism policymakers, tourist hotel owners, hoteliers and tourism managers in their decision-making.
Practical implications - This study provides strategic implications for practitioners and operators in hospitality industry to evaluate the factors ensuring hotel profitability in periods of EPU.
Originality/value - This paper provides interesting insights into the characteristics and practices of profitable hotels in Italy. Few econometric studies empirically explored the effects of EPU in the hospitality field so far and no prior study investigated this topic in the Italian hospitality sector. Therefore, this paper tries to close an important gap in the existing literature improving the understanding of EPU in the Italian hospitality industry
Forward-Looking Intellectual Capital Information in Integrated Reporting: An Empirical Analysis
No full textThe aim of the paper is to explore the amount of forward-looking intellectual capital information (FL_ICI) in
Integrated Reporting (IR) and the effect of firm characteristics on FL_ICI within this context. This study
empirically bridges the research gap on the issues of forward-looking information (FLI) and adds to intellectual
capital (IC) disclosure research. In particular, the paper responses to two research questions specifically: what
are the extent and the content of FL_ICI and what are the factors that impact on different IC voluntary reporting
behaviors in IR. A content analysis is apply to inspect the subjects and the amount of FL_ICI in reports
accessible in the web site of the International Integrated Reporting Council. Five Models are verified using a
multivariate regression analysis to investigate the influence of three independent variables (firm size,
profitability and leverage) on FL_ICI. The research proves that companies are reluctant to disclose FL_ICI in
integrated reports. The findings of the research show that the majority of FL_ICI regards relational capital. The
regression model also reveals that firm size and profitability have a statistically significant influence on specific
topics of FL_ICI. On the contrary, leverage appears insignificant in determining the amount of FL_ICI. The
research contributes to prior disclosure literature regarding forward-looking information since prior research
results are unclear. There is a limited number of studies that investigated FL_ICI in relation to firm
characteristics and no studies have investigated this issue within the setting of IR
The interferon-stimulated gene TRIM22 : A double-edged sword in HIV-1 infection
No full textInfection of target cells by the human immunodeficiency virus type-1 (HIV-1) is hampered by constitutively expressed host cell proteins preventing or curtailing virus replication and therefore defined as “restriction factors”. Among them, members of the tripartite motif (TRIM) family have emerged as important players endowed with both antiviral effects and modulatory capacity of the innate immune response. TRIM5α and TRIM19 (i.e. promyelocytic leukemia, PML) are among the best-characterized family members; however, in this review we will focus on the potential role of another family member, i.e. TRIM22, a factor strongly induced by interferon stimulation, in HIV infection in vivo and in vitro in the context of its broader antiviral effects. We will also focus on the potential role of TRIM22 in HIV-1-infected individuals speculating on its dual role in controlling virus replication and more complex role in chronic infection. At the molecular levels, we will review the evidence in favor of a relevant role of TRIM22 as epigenetic inhibitor of HIV-1 transcription acting by preventing the binding of the host cell transcription factor Sp1 to the viral promoter. These evidences suggest that TRIM22 should be considered a potential new player in either the establishment or maintenance of HIV-1 reservoirs of latently infected cells unaffected by combination antiretroviral therapy
