The effects of protection measures on fish assemblage in the Plemmirio marine reserve (Central Mediterranean Sea, Italy): A first assessment 5years a…

2013

This 2-year study was aimed to investigate the early effects of protection measures on fish assemblage in the Plemmirio marine reserve and to evaluate its level of enforcement. Sampling was carried out by means of underwater visual census techniques in four sampling sites within the reserve boundaries and eight outside the reserve. Results showed significant inside/outside differences in the multivariate abundance of fish assemblage. These results were confirmed and exemplified by significant univariate differences between locations for total abundance, Species Richness and diversity of the fish assemblage; values of these metrics were higher inside the reserve than outside. Small fish size…

A simulation study for assessing the impact of energy storage systems for Fast Reserve with additional synthetic inertia control on the Continental E…

2022

This article shows the results of a simulation study on the application of battery storage systems for providing fast frequency regulation (the so-named Fast Reserve) with additional synthetic inertia control. The aim of the study is to assess the impact of the extension of the regulation provided by the FRUs to all the Continental Europe synchronous grid, with the same power proportions of the first Italian FRU auction. The simulations are conducted in two different scenarios: a base one related to 2020 and a future one related to 2040 and based on ENTSO-E projections for load and generation. The results show that, for the reference incident of 3000 MW, the frequency quality parameters in …

L’analisi delle simbolizzazioni affettive delle Aree Naturali Protette per un turismo responsabile. Il caso studio delle Riserva Naturale Orientata d…

2013

ABSTRACT This paper presents a research on responsible tourism in protected areas, through the case study of Zingaro Nature Reserve (Sicily). The main objectives of this study were to examine the so-called collusive processes elaborated by different stakeholder of natural protected area and to propose strategies and guidelines for intervention in the perspective of sustainable development and responsible use of the local tourist activities, based on the results. The methodology applied was Emotional Analysis of the Text (EAT) that allowed to investigate the emotional representations and the expectations of stakeholders, through the study of co-occurrances of the so-called dense words, using…

ALBERT O. HIRSCHMAN AT THE FEDERAL RESERVE, 1946–1952

2022

This essay introduces the work conducted by Albert O. Hirschman at the Federal Reserva Bank. His main areas of interest, on which he produce original research, were European postwar reconstruction and integration; country studies (Italy and France, particularly), alternative modes of economic development; the role of the US in assisting reconstruction and development.

The cost and actuarial imbalance of pay‐as‐you‐go systems: the case of Spain

2010

This work determines the actuarial cost of delivering a monetary unit of pension in the case of a pay‐as‐you‐go system. The model is also applied to determining the imbalance and the unitary pension cost of the contributory pension system of the Spanish Social Security system. The study covers all benefits and all regimes for five consecutive years from 2002 to 2006. Policy alternatives are presented that would allow the system to be brought back into balance by actuarially equating the cost to the value of the pension delivered.

An Actuarial Balance Model for DB PAYG Pension Systems with Disability and Retirement Contingencies

2012

In this paper we develop a theoretical basis for drawing up a “Swedish” type actuarial balance sheet for a defined benefit pay-as-you-go (DB PAYG) scheme with retirement and disability benefits. Our model enables us to obtain the system's expected average turnover duration, measure the scheme's solvency and explore the phenomenon identified as “pension reclassification”, a widespread practice that masks the system's real status unless further pension information becomes available. The model is clearly linked to actuarial practice in social security and gives partial support to the practical adaptation of Swedish methodology carried out by OSFI (2012) in applying the concept of the contribut…

Is the Reform of the Spanish Public Pension System of 2011 Justified from an Actuarial Point of View?

2012

The aim of this paper is basically to answer three questions about the Spanish public retirement pension system. Is the 2011 reform of the system, which will gradually come into force starting on 1-01-2013, justified from an actuarial point of view? What measures would have been adopted in the Spanish system if all the accounting principles applied in the notional account pension system in Sweden were enforced? What measures would be adopted if current legislation on defined benefit private pension plans were applied to the system? To this end we formulate a Swedish-type actuarial balance for the Spanish public retirement pension system as at 31-12-2010 and project a solvency indicator for …
