La teoria del diritto come pratica sociale e la coercizione

2020

Poiche non si puo trattare del posto che la coercizione ha nel concetto di diritto senza far riferimento ad una specifica teoria del diritto, il paper ricostruisce le linee generali della teoria del diritto come pratica sociale, focalizzando in particolare l’obiettivo del diritto di custodire l’agency dei consociati per contrastare l’uso arbitrario del potere. Nella seconda parte si affronta dal punto di vista del diritto come pratica sociale il tema generale della coercizione giuridica e ci si chiede soprattutto se l’uso giuridico della forza non sia anch’esso nella sostanza una forma di potere che contraddice il fine generale della custodia dell’agency.

Annual flow duration curves assessment in ephemeral small basins

2014

Flow duration curve (FDC) represents a comprehensive signature of temporal runoff variability often used to synthesize catchment rainfall-runoff responses. A new model, the ModABa (MODel for Annual flow duration curves assessment in ephemeral small BAsins), is here introduced. It can be thought as a wide mosaic whose tesserae are frameworks, models or conceptual schemes separately developed in different studies and harmoniously interconnected with the final aim of reproducing the annual FDC in intermittent small catchments. Two separated seasons within the hydrological year are distinguished: a dry season, characterized by absence of streamflow, and a non-zero season. Streamflow is disaggre…

Ecohydrological modelling of flow duration curve in Mediterranean river basins

2013

Abstract Flow duration curve provides an important synthesis of the relevant hydrological processes occurring at the basin scale, and, although it is typically obtained from field observations, different theoretical approaches finalized to its indirect reconstruction have been developed in recent years. In this study a recent ecohydrological model for the probabilistic characterization of base flows is tested through its application to a study catchment located in southern Italy, where long historical series of daily streamflow are available. The model, coupling soil moisture balance with a simplified scheme of the hydrological response of the basin, provides the daily flow duration curve. …

Comparative analysis of different techniques for spatial interpolation of rainfall data to create a serially complete monthly time series of precipit…

2011

Abstract The availability of good and reliable rainfall data is fundamental for most hydrological analyses and for the design and management of water resources systems. However, in practice, precipitation records often suffer from missing data values mainly due to malfunctioning of raingauge for specific time periods. This is an important issue in practical hydrology because it affects the continuity of rainfall data and ultimately influences the results of hydrologic studies which use rainfall as input. Many methods to estimate missing rainfall data have been proposed in literature and, among these, most are based on spatial interpolation algorithms. In this paper different spatial interpo…

Ecohydrology in Mediterranean areas: a numerical model to describe growing seasons out of phase with precipitations

2008

The probabilistic description of soil moisture dynamics is a relatively new topic in hydrology. The most common ecohydrological models start from a stochastic differential equation describing the soil water balance, where the unknown quantity, the soil moisture, depends both on spaces and time. Most of the solutions existing in literature are obtained in a probabilistic framework and under steady-state condition; even if this last condition allows the analytical handling of the problem, it has considerably simplified the same problem by subtracting generalities from it. <br><br> The steady-state hypothesis, appears perfectly applicable in arid and semiarid climatic areas like th…

La natura delle cose

2022

The reference to the nature of things is still working today in legislation and jurisprudence. In this article the reasons for the persistence of this line of reasoning in law and in the legal science are examined. These reasons generally depend on the close connection between law and some fundamental social relations. But also the essential need to assure its effectiveness, without which law would be useless. In turn, the contemporary evolution of the legal culture requires a change in the way of understanding the nature of things. Nowadays, the nature of things distances itself from mere objectivism to get close to the deliberative character of the determination of the law

Multilayer blue-green roofs as nature-based solutions for water and thermal insulation management

2022

Abstract Green roofs have been widely recognized as sustainable nature-based solutions to mitigate floods in urban areas, which, in the last decades, are increasing due to the combination of intense worldwide urbanization and climate change. Besides flood mitigation, green roofs provide additional benefits for the urban environment (e.g., reducing the urban heat island and ensuring energy saving for the underneath building). Moreover, green roofs facilitate the increase of urban biodiversity, attracting different species of small animals, and upgrade the city aesthetic value. Among the different types of green roofs, multilayer blue-green roofs present an additional layer to store water dur…

Climate change effects on the hydrological regime of small non-perennial river basins.

2015

Recent years have been witnessing an increasing interest on global climate change and, although we are only at the first stage of the projected trends, some signals of climate alteration are already visible. Climate change encompasses modifications in the characteristics of several interrelated climate variables, and unavoidably produces relevant effects on almost all the natural processes related to the hydrological cycle. This study focuses on potential impacts of climate variations on the streamflow regime of small river basins in Mediterranean, seasonally dry, regions. The paper provides a quantitative evaluation of potential modifications in the flow duration curves (FDCs) and in the p…

Effectiveness of anti-vascular endothelial growth factors in neovascular age-related macular degeneration and variables associated with visual acuity…

2021

Objective To assess the overall effectiveness of anti-vascular endothelial growth factor (VEGF) therapy in treatment-naïve patients with neovascular age-related macular degeneration (nAMD) in a clinical practice setting. Study design EAGLE was a retrospective, 2-year, cohort observational, multicenter study conducted in Italy that analyzed secondary data of treatment-naïve patients with nAMD. The primary endpoint evaluated the mean annualized number of anti-VEGF injections at Years 1 and 2. The main secondary endpoints analyzed the mean change in visual acuity (VA) from baseline and variables associated with visual outcomes at Years 1 and 2. Results Of the 752 patients enrolled, 745 (99.07…

Olive Yield and Future Climate Forcings

2013

Abstract The rainfall reduction and the temperature increase forecasted for Mediterranean regions would likely increase the vegetation water stress and decrease productivity in rainfed agriculture. Olive trees, which have traditionally been grown under rainfed conditions, are one of the most characteristic tree crops from the Mediterranean not only for economical importance but also for minimizing erosion and desertification and for improving the carbon balance of these areas. In order to simulate how climatic change could alter soil moisture dynamics, biomass growth and fruit productivity, a water driven crop model is used in this study. The model quantitatively links olive yield to climat…

EHSM: a conceptual ecohydrological model for daily streamflow simulation

2013

A parsimonious conceptual lumped model is here presented with the aim of simulating daily streamflow in semi-arid areas. The model, processing daily rainfall and reference evapotranspiration at basin scale, reproduces surface and subsurface runoff, soil moisture dynamics, and actual evapotranspiration fluxes. The key elements of this numerical model are the soil bucket, where rainfall, evapotranspiration, and leakage drive soil moisture dynamics, and two linear reservoirs working in parallel with different characteristic response times. The surface reservoir, able to simulate the fast response of the basin, is fed by rain falling on impervious area and by runoff generated with excess of sat…

Generation of Natural Runoff Monthly Series at Ungauged Sites Using a Regional Regressive Model

2016

Many hydrologic applications require reliable estimates of runoff in river basins to face the widespread lack of data, both in time and in space. A regional method for the reconstruction of monthly runoff series is here developed and applied to Sicily (Italy). A simple modeling structure is adopted, consisting of a regression-based rainfall–runoff model with four model parameters, calibrated through a two-step procedure. Monthly runoff estimates are based on precipitation, temperature, and exploiting the autocorrelation with runoff at the previous month. Model parameters are assessed by specific regional equations as a function of easily measurable physical and climate basin descriptors. Th…

The SESAMO early warning system for rainfall-triggered landslides

2016

The development of Web-based information systems coupled with advanced monitoring systems could prove to be extremely useful in landslide risk management and mitigation. A new frontier in the field of rainfall-triggered landslides (RTLs) lies in the real-time modelling of the relationship between rainfall and slope stability; this requires an intensive monitoring of some key parameters that could be achieved through the use of modern and often low-cost technologies. This work describes an integrated information system for early warning of RTLs that has been deployed and tested, in a prototypal form, for an Italian pilot site. The core of the proposed system is a wireless sensor network coll…

Future Climate Forcings and Olive Yield in a Mediterranean Orchard

2014

The olive tree is one of the most characteristic rainfed trees in the Mediterranean region. Observed and forecasted climate modifications in this region, such as the CO2 concentration and temperature increase and the net radiation, rainfall and wind speed decrease, will likely alter vegetation water stress and modify productivity. In order to simulate how climatic change could alter soil moisture dynamic, biomass growth and fruit productivity, a water-driven crop model has been used in this study. The numerical model, previously calibrated on an olive orchard located in Sicily (Italy) with a satisfactory reproduction of historical olive yield data, has been forced with future climate scenar…

Performances of GPM satellite precipitation over the two major Mediterranean islands

2018

Reliable and accurate precipitation measurement or estimation is crucial for disaster monitoring and water resource management. However, obtaining accurate high-resolution precipitation fields is still a challenging task for scientists and practitioners, especially in the poorer region of the world. Nowadays the scientific community expects significant improvements in precipitation monitoring by the continuous technological evolution of satellite-rainfall estimate systems which are able to produce data with global coverage and thus can provide low-cost information even in scarcely populated areas or places where for economic reasons ground measures are missing. The most recent satellite mis…

The Family’s Role in the Twilight of Political Community

2021

The social history of modernity shows a progressive and accelerated decline of the political importance of the family. At the same time Politics also finds it more and more difficult to recognize itself as a community of life. We have to ask ourselves whether between the politica! irrelevance of the family and the loss of the community dimension of Politics there is a causa! connection, or at least a significant correlation.

Spatial distribution of temperature trends in Sicily

2013

Climate change resulting from the enhanced greenhouse effect is expected to have great impacts on hydrological cycle and consequently on ecosystems. The effects of climate variability have direct implications on water management, as water availability is related to changes in temperature and precipitation regimes. At the same time, this kind of alterations drives ecological impacts on flora and fauna. For these reasons, many studies have been carried out to investigate the existence of some tendency in temperature and/or precipitation series in different geographic domains. In order to verify the hypothesis of temperature increase in Sicily (Italy), temperature data from about 80 spatially …

Annual runoff regional frequency analysis in Sicily

2009

Abstract This paper performs annual runoff frequency analysis in Sicily, Italy using the index runoff method. Homogeneous regions, not necessarily defined by geographical boundaries but sharing common features from a morphologic and climatic standpoint, have been identified. For each region a single probability distribution function can be fitted to the available annual runoff data scaled by the index runoff. Starting from an initial dataset of 105 hydrometric stations, 57 stations have been selected using heuristic criteria associated with the Hosking and Wallis’s discordancy measure. The Mantel tests have been then applied to find out the physical and morphological parameters best correla…

Which Foundation for Human Rights?

2021

The article argues the thesis according to which the problem of the foundation of human rights is not well formulated in the classic debate on it. The reason is that there are different kinds of foundations, depending on the different concepts of human rights, but also in consideration of the different aspects of their practice. The question is then which foundation fits with a notion of human rights as a legal and social practice. The second part is dedicated to the analysis of the idea that the practice of human rights is part of the current jus gentium. It aims at showing the implications of that relationship in terms of their appropriate legal grounds.

Co-evolution of hydrological components under climate change scenarios in the Mediterranean area

2015

ABSTRACT The Mediterranean area is historically characterized by high human pressure on water resources. Today, while climate is projected to be modified in the future, through precipitation decrease and temperature increase, that jointly and non-linearly may affect runoff, concerns about water availability are increasing. For these reasons, quantitative assessment of future modifications in the mean annual water availability are important; likewise, the description of the future interannual variability of some hydrological components such as runoff and evapotranspiration are highly wished for water management and ecosystems dynamics analyses. This study investigates at basin spatial scale …

Effect of climate change on asphalt binder selection for road construction in Italy

2015

This work explores the influence of climate changes on the proper selection of asphalt binder for pavement construction purposes, according to the Performance Grade (PG) defined in the SUPERPAVE specifications. Based on temperature data at national level, it is possible to obtain thematic maps for the whole Italian territory, which is extremely useful for technicians and pavement engineers for selection of asphalt binder for road construction purposes. Furthermore, the statistical significant temperature trends’ knowledge enables deriving thematic maps which allows to include the effects of climate change in the asphalt binder design. It is argued that, due to climate change, the binders to…

An automatic tool for reconstructing monthly time-series of hydro-climatic variables at ungauged basins

2017

Abstract Integrative information models for filling/reconstructing hydro-climatic time-series are required for a variety of practical applications. A GIS-based model for a rapid and reliable assessment of monthly time-series of several key hydro-climatic variables at the basin scale, is here developed as plug-in and applied to the entire region of Sicily (Italy). The plug-in, once the desired basin outlet section and time-window are selected, uses appropriate spatial techniques and algorithms to identify its drainage area and estimate the corresponding mean areal rainfall and temperatures time-series. A recent regional regressive rainfall-runoff model is successively applied for the assessm…

Olive yield as a function of soil moisture dynamics

2011

This study introduces a water-driven crop model aiming to quantitatively link olive yield to climate and soil moisture dynamics using an ecohydrological approach. A mathematical model describing soil moisture, evapotranspiration and assimilation dynamics of olive orchards is developed here. The model is able to explicitly reproduce two different hydroclimatic phases in Mediterranean areas: the well-watered conditions in which evapotranspiration and assimilation assume their maximum values and the real conditions where the limitations induced by soil moisture availability are taken into account. Annual olive yield is obtained by integrating the carbon assimilation during the growing season, …

Transient soil-moisture dynamics and climate change in Mediterranean ecosystems

2008

[1] Plants in Mediterranean ecosystems have developed different strategies to cope with transient soil-moisture dynamics induced by the markedly out of phase seasonal behavior of rainfall and temperature. Deep-rooted plants use the soil moisture stored in the wet winter (extensive users), while shallower rooted plants exploit both the wet season storage and the more sporadic growing season rainfall (intensive users). Using stochastic models of soil-moisture dynamics, we present an analytical and numerical description of the probabilistic structure of the soil-moisture storage at the beginning of the growing season in relation to the dynamics of the wet season and then study its evolution du…

Daily streamlow prediction with uncertainty in ephemeral catchments using the GLUE methodology

2009

Abstract The Generalised Likelihood Uncertainty Estimation (GLUE) approach is presented here as a tool for estimating the predictive uncertainty of a rainfall–runoff model. The GLUE methodology allows to recognise the possible equifinality of different parameter sets and assesses the likelihood of a parameters set being acceptable simulator when model predictions are compared to observed field data. The results of the GLUE methodology depend greatly on the choice of the likelihood measure and on the choice of the threshold which determines if a parameters set is behavioural or not. Moreover the sampling size has a strong influence on the uncertainty assessment of the response of a rainfall–…

Hans Kelsen and Practical Reason

2017

The critique of practical reason, in all its possible forms, has a far more important and decisive role in Kelsen’s thought than the rejection of Natural law doctrine. Admitting that a practical use of reason is legitimate, namely, that there is a possible connection between intellect and will, would mean destroying the whole foundation of the scientific undertaking of the Pure Theory of law and its conception of the legal norm, which is its central aspect. By depriving practical reason of all foundation, any reference to agency and practical deliberation is excluded from Kelsen’s theory of law. Consequently, the Ought loses all capacity of attraction and motivation of human action, renderi…

Europe’s Path to Public Reason

2012

Chapter 7 highlights how addressing public issues publicly is a main target of European institutions, considering their commitment to the identification of shared values and the protection of rights. In consideration of this, it is reasonable to ask whether the “Public Reason” set forth by Rawls can be somehow applied to Europe’s current perspective, understanding it to be the ruling criterion governing public issues. A major obstacle is to be found in the anti-pluralistic attitude which is widespread across the European states. However, constitutionalism, which is nowadays widely rooted on a global scale, makes contemporary political communities to characterize by disagreement and by the n…

Climate changes' effects on vegetation water stress in Mediterranean areas

2010

Many recent studies have demonstrated that CO(2) increase is driving the climate in Mediterranean areas towards important changes, mainly represented by a temperature increase and a contemporaneous rainfall reduction. Starting from this premise, the primary aim of the present study is to investigate the effects of potential climatic changes on vegetational stress in Mediterranean ecosystems. Particular attention is here focussed only on the plants' water stress in water controlled ecosystems, mainly related to soil water balance. The interactions among climate, soil and vegetation are evaluated numerically by means of an ecohydrological model. In this work, different future climatic scenari…

Tetti verdi multistrato per lo sviluppo sostenibile di città resilienti: quattro casi studio italiani

2021

Negli ultimi anni le inondazioni in ambito urbano sono state sempre più frequenti, provocando notevoli danni sia livello sociale che a livello economico. Questo fenomeno è in parte determinato da un aumento di urbanizzazione causato dalla crescita della popolazione, che tende sempre più a spostarsi dalle zone rurali alle aree urbane, che si espandono molto velocemente, spesso con infrastrutture idrauliche inadeguate. Inoltre, a causa di cambiamenti climatici, soprattutto nelle aree mediterranee, si può osservare un aumento di lunghi periodi di siccità, intervallati da piogge di breve durata, ma di sempre più forte intensità e frequenza. La presenza di questi fenomeni di pioggia intensa, in …

Spatial distribution of rainfall trends in Sicily (1921–2000)

2006

Abstract The feared global climate change could have important effects on various environmental variables including rainfall in many countries around the world. Changes in precipitation regime directly affect water resources management, agriculture, hydrology and ecosystems. For this reason it is important to investigate the changes in the spatial and temporal rainfall pattern in order to improve water management strategies. In this study a non-parametric statistical method (Mann–Kendall rank correlation method) is employed in order to verify the existence of trend in annual, seasonal and monthly rainfall and the distribution of the rainfall during the year. This test is applied to about 25…

Salinity and periodic inundation controls on the soil-plant-atmosphere continuum of gray mangroves

2017

Salinity and periodic inundation are both known to have a major role in shaping the ecohydrology of mangroves through their controls on water uptake, photosynthesis, stomatal conductance, gas-exchanges and nutrient availability. Salinity, in particular, can be considered one of the main abiotic regulating factors for halophytes and salt tolerant species, due to its influence on water use patterns and growth rate. Ecohydrological literature has rarely focused on the effects of salinity on plant transpiration, based on the fact that the terrestrial plants mostly thrive in low saline, unsaturated soils where the role of osmotic potential can be considered negligible. However, the effect of sal…

The state of water resources in major mediterranean islands

2014

This work analyses the state of water resources in six Mediterranean islands: Corsica, Crete, Cyprus, Mallorca, Malta and Sicily. The analysis is focused on the prevailing social, economic and hydroclimatological characteristics of these islands in order to identify the main common features affecting water availability, demand and use. A detailed analysis of the state of water resources in all the considered islands has been carried out. A background of current conditions relating to freshwater availability, quality and use has been established. Different strategies to face water scarcity and enhance water quality in theislands have been assessed in a context of climate change which is a co…

Budyko’s Based Method for Annual Runoff Characterization across Different Climatic Areas: an Application to United States

2018

Runoff data knowledge is of fundamental importance for a wide range of hydrological, ecological, and socioeconomic applications. The reconstruction of annual runoff is a fundamental task for several activities related to water resources management, especially for ungauged basins. At catchment scales, the Budyko's framework provides an extremely useful and, in some cases, accurate estimation of the long-term partitioning of precipitation into evapotranspiration and runoff as a function of the prevailing climatic conditions. Recently the same long-term partitioning rules have been successfully used to describe water partitioning also at the annual scale and calculate the annual runoff distrib…

Regional flow duration curves for ungauged sites in Sicily

2011

Abstract. Flow duration curves are simple and powerful tools to deal with many hydrological and environmental problems related to water quality assessment, water-use assessment and water allocation. Unfortunately the scarcity of streamflow data enables the use of these instruments only for gauged basins. A regional model is developed here for estimating flow duration curves at ungauged basins in Sicily, Italy. Due to the complex ephemeral behaviour of the examined region, this study distinguishes dry periods, when flows are zero, from wet periods using a three parameters power law to describe the frequency distribution of flows. A large dataset of streamflows has been analysed and the param…

Comparative Analysis of Spatial Interpolation Methods in the Mediterranean Area: Application to Temperature in Sicily

2015

An exhaustive comparison among different spatial interpolation algorithms was carried out in order to derive annual and monthly air temperature maps for Sicily (Italy). Deterministic, data-driven and geostatistics algorithms were used, in some cases adding the elevation information and other physiographic variables to improve the performance of interpolation techniques and the reconstruction of the air temperature field. The dataset is given by air temperature data coming from 84 stations spread around the island of Sicily. The interpolation algorithms were optimized by using a subset of the available dataset, while the remaining subset was used to validate the results in terms of the accur…

Annual runoff assessment in arid and semiarid Mediterranean watersheds under the Budyko's framework

2017

The solution of many practical water problems is strictly connected to the availability of reliable and widespread information about runoff. The estimation of mean annual runoff and its interannual variability for any basin over a wide region, even if ungauged, would be fundamental for both water resources assessment and planning and for water quality analysis. Starting from these premises, the main aim of this work is to show a new approach, based on the Budyko's framework, for mapping the mean annual surface runoff and deriving the probability distribution of the annual runoff in arid and semiarid watersheds. As a case study, the entire island of Sicily, Italy, is here proposed. First, ti…

Parametric uncertainty or hydrological changes?

2014

Abstract. The model calibration is the way of hydrologists for searching also a physical interpretation of complex interactions acting within a basin. Actually, it can be frequently noticed how model calibration performed on a given time-window may converge to a point in the parameter space that could be distant from another obtainable calibration of the model in the same basin but considering a different time window. Is that again parametric uncertainty or does the trajectory in the parametric space relate about to a slow hydrological basin change? This paper depicts a possible path for detecting changes' signatures in a streamflow time series. In particular, the paper seeks to draw a way …

Rainfall statistics changes in Sicily

2013

Abstract. Changes in rainfall characteristics are one of the most relevant signs of current climate alterations. Many studies have demonstrated an increase in rainfall intensity and a reduction of frequency in several areas of the world, including Mediterranean areas. Rainfall characteristics may be crucial for vegetation patterns formation and evolution in Mediterranean ecosystems, with important implications, for example, in vegetation water stress or coexistence and competition dynamics. At the same time, characteristics of extreme rainfall events are fundamental for the estimation of flood peaks and quantiles which can be used in many hydrological applications, such as design of the mos…

Wind speed and temperature trends impacts on reference evapotranspiration in Southern Italy

2014

In this study, the impacts of both temperature and wind speed trends on reference evapotranspiration have been assessed using as a case study the Southern Italy, which present a wide variety of combination of such climatic variables trends in terms of direction and magnitude. The existence of statistically significant trends in wind speed and temperature from observational datasets, measured in ten stations over Southern Italy during the period 1968–2004, has been investigated. Time series have been examined using the Mann–Kendall nonparametric statistical test in order to detect possible evidences of wind speed and temperature trends at different temporal resolution and significance level.…

Negotiation of Identities and Negotiation of Values in Multicultural Societies

2014

This chapter addresses the notions of identity negotiation and value negotiation from a philosophical perspective. The relationship between personal or collective identity and core values is here analyzed. Identity is described as constituted by a set of core values. Yet, while identity is—by definition—particular, core values intend to be universal although they are practiced in particular cultural contexts and are susceptible of different interpretations and applications. The author claims that whether negotiation is meant in contractual terms, it is an adequate tool only to manage interests but not identitarian values. However, if negotiation is meant as a process of gradual adaptation t…

Geostatistical techniques for runoff mapping: an application to Sicily, Italy

2011

The availability of reliable and long time series of runoff data is fundamental for most of the hydrological analyses and for the assessment and the management of water resources even in condition of global climatic change. However, hydrologic data sets are often characterized by a short duration and also suffer from missing data values, mainly due to malfunctioning of gauging stations for a specific period. In order to overcome this problem and obtain long and continuous runoff time series, different models and methods have been previously developed and proposed. While some models, used to extent the streamflow record, are conceptual, empirical, regressive models based on the rainfall inpu…

The purpose of this essay is to show that philosophical hermeneutics is particularly suited for facing problems of understanding among different cultural worlds. These issues are relevant even for legal interpretation that, now more than ever, is not up against culturally homogeneous societies and against legal systems shaped by a single source or by a steady hierarchy of sources. Therefore, philosophical hermeneutics’ approaches to intercultural dialogue can be useful to the present practice of legal interpretation, not by building new interpretative methods, but by clarifying contexts which give significance to legal practice. The paths trodden by legal philosophical hermeneutics are devo…

Development of innovative approaches for evaluating drought vulnerability and selecting innovative practices for managing water shortage (in Sicily)

2013

The climate, especially with regard to the precipitation and the evapotranspiration processes, plays a fundamental role in the vegetational patterns formation and modifications. The pilot project here described tries to evaluate in a quantitative way the impact of different climatic regimes (current or future) on vegetation health status and its physiological processes. In particular, an ecohydrological approach has been adopted in order to carry out an analysis of the potential climate changes influence on the vegetation state in a typical Mediterranean environment, such as the Sicilian one.

Investigating the changes in extreme rainfall in Sicily

2012

Changes in extreme rainfall are one of the most relevant sign of current climate alterations. Many studies have demonstrated an increase in rainfall intensity and a reduction of frequency in several areas of the world. This could be probably due to an acceleration of the hydrological cycle caused by temperature increase and could have, as consequence, the increase of flooding hazard. In the past, Sicily has been screened for several signals of possible climate change. Annual, seasonal and monthly rainfall data in the entire Sicilian region have been analyzed, showing a global reduction of total annual rainfall, which is mainly due to the winter reduction. Moreover, some annual maximum rainf…

Neuroscienze e diritto naturale

2014

In the first three sections of this paper, the author examines the ambiguous usage of legal and moral terminology in the field of neurosciences. The fourth section is devoted to the analysis of the natural law tradition: obviously in this context naturalistic tendencies have been opposed and isolated by the forbiddance derived from the naturalistic fallacy argument. The question is whether neurosciences can attribute a new (by any chance different and debatable) role to the “nature” in law and morals.

EHSMu: a new conceptual model for hourly discharge simulation under ecohydrological framework in urban area

2013

A parsimonious conceptual lumped model is presented here with the aim of simulating hourly discharge in urban areas. The EHSMu (EcoHydrological Streamflow Model for urban areas) is able to reproduce the discharge at the outlet of an urban drainage system and, at the same time, soil moisture dynamics and evapotranspirative fluxes over vegetated areas within an urban catchment. In urban areas, rain falling over impervious surfaces is directly transferred towards the drainage system in a time depending on the catchment characteristics, and drainage network geometry. If the rain falls over pervious and vegetated areas the runoff generation is driven by soil moisture content, which in turn is li…

Long term analysis of small desalination plant for potable water supply of tourist areas (in Sicily)

2013

The main aim of this work is to gain information on the working conditions of a desalination plant in Sicily, on the costs of produced desalinated water and on the perspectives of new plants to be built in the island, in order to evaluate the long term performance of a desalination plant in a small island for potable water supply. At the same time, because the high operational costs, the work tries to provide green power alternatives for the plant as well. As a pilot we will consider the Lipari Island which has a MED-MVC (Multiple Effect Distillation- Mechanical Vapor Compression) plant. It is important to underline that even though the pilot refers to a Sicilian Island, the developed proce…

Europe's Path to Public Reason

2012

Chapter 7 highlights how addressing public issues publicly is a main target of European institutions, considering their commitment to the identification of shared values and the protection of rights. In consideration of this, it is reasonable to ask whether the "Public Reason" set forth by Rawls can be somehow applied to Europe's current perspective, understanding it to be the ruling criterion governing public issues. A major obstacle is to be found in the anti-pluralistic attitude which is widespread across the European states. However, constitutionalism, which is nowadays widely rooted on a global scale, makes contemporary political commu¬nities to characterize by disagreement and by the …

EHSM: a new conceptual model for daily streamflow simulation under ecohydrological framework

2011

A parsimonious conceptual lumped model is presented here with the aim of simulating daily streamflow in semi-arid areas. The model is able to reproduce surface and sub-surface runoff, soil moisture dynamics and evapotranspirative fluxes, averaged over a basin starting from daily time series of rainfall and temperature and from the initial value of soil. The rainfall is partioned in two components: the first, which interests a totally impermeable area, is routed directly on a superficial linear reservoir, while the second passes through permeable soil. If the rainfall input exceeds the soil storage capacity, which is a function of soil moisture at that specific time, this saturation excess i…

Religione civile: uso e abuso di un concetto

2013

Civil religion: uses and misuses of a concept. The analysis of the concept of “civil religion” shows an ambiguity caused by the mix between religion and morality, and religion and politics. The idea behind is the sacralization of politics in order to assure its autonomy from historic religions. Civil religion supporters individuate in this cultural position two positive results: the opening of politics to transcendence and the ethical legitimation of communitarian linkages. The article examines these two aspects, in the light of constitutionalism, human rights and current pluralism. The conclusion is that the concept must be considered misleading.

Influence of rating curve uncertainty on daily rainfall–runoff model predictions

2005

River discharge observations are usually affected by uncertainty, which is due to many concurrent causes and strongly affects the response of rainfall-runoff models. The present paper is aimed at studying the influence of imperfect rating curve knowledge on the uncertainty of the response of a daily conceptual linear-nonlinear rainfall-runoff model. To describe the impact of imperfect rating curve knowledge, simulations have been conducted using a conceptual rainfall-runoff model and continuous daily series of rainfall, air temperature and discharges recorded in a Sicilian catchment. The GLUE procedure was used to introduce the uncertainty of the rating curve in a classical rainfall-runoff …

Soil moisture limiting olive orchard evapotranspiration

2011

Two years of field data concerning soil moisture dynamics and water vapor fluxes over a rainfed olive orchard in Sicily are presented here in order to understand how climate, seasonality, water availability and farming practices drive evapotranspiration in such a peculiar Mediterranean vegetation. Soil moisture has been measured in two different points characterized by a uniformly sandy soil and at multiple depths up to 1.2 m. The observed dynamics are driven by rainfall inputs, which are frequent during the winter season and rare during the growing season, and by vegetation uptakes, which deplete the water stored in the soil. The top layers soil moisture status is much more time dependent …

Analisi della affidabilità dei database pluviometrici globali a scala locale. Applicazione al territorio siciliano

2012

Negli ultimi anni i sistemi di misurazione e di stima delle precipitazioni, sono stati arricchiti dalla possibilità di ottenere stime attraverso dati acquisiti da sensori satellitari. I prodotti di stima così ottenuti risultano comunque spesso fortemente distorti. Per tale ragione le stime sulla base di soli dati satellitari, vengono ulteriormente elaborate attraverso l'utilizzo di dataset che raccolgono dati di precipitazione provenienti da reti pluviografiche al fine di ridurre la distorsione che caratterizza i dati satellitari. È auspicabile che questi dataset siano quanto più precisi al fine di fornire dati adatti alla correzione dei dati satellitari e in particolare alla riduzione dell…

Detecting hydrological changes through conceptual model

2015

Natural changes and human modifications in hydrological systems coevolve and interact in a coupled and interlinked way. If, on one hand, climatic changes are stochastic, non-steady, and affect the hydrological systems, on the other hand, human-induced changes due to over-exploitation of soils and water resources modifies the natural landscape, water fluxes and its partitioning. Indeed, the traditional assumption of static systems in hydrological analysis, which has been adopted for long time, fails whenever transient climatic conditions and/or land use changes occur. Time series analysis is a way to explore environmental changes together with societal changes; unfortunately, the not disting…

Analitical deriving of the field capacity through soil bundle model

2015

The concept of field capacity as soil hydraulic parameter is widely used in many hydrological applications. Althought its recurring usage, its definition is not univocal. Traditionally, field capacity has been related to the amount of water that remains in the soil after the excess water has drained away and the water downward movement experiences a significant decresase. Quantifying the drainage of excess of water may be vague and several definitions, often subjective, have been proposed. These definitions are based on fixed thresholds either of time, pressure, or flux to which the field capacity condition is associated. The flux­based definition identifies the field capacity as the soil m…

Transient Soil Moisture Dynamics and Climate Change in Mediterranean Ecosystems

2008

Plants in Mediterranean ecosystems have developed different strategies to cope with transient soil-moisture dynamics induced by the markedly out of phase seasonal behavior of rainfall and temperature. Deep-rooted plants use the soil moisture stored in the wet winter (extensive users), while shallower rooted plants exploit both the wet season storage and the more sporadic growing season rainfall (intensive users). Using stochastic models of soil moisture dynamics, we present an analytical and numerical description of the probabilistic structure of the soil-moisture storage at the beginning of the growing season in relation to the dynamics of the wet season, and then study its evolution durin…

Evaluating the performances of an ecohydrological model in semi-arid river basins

2013

The EHSM (EcoHydrological Streamflow Model) is a conceptual lumped model aimed to daily streamflow simulation. The model, processing daily rainfall and reference evapotranspiration at the basin scale, reproduces surface and subsurface runoff, soil moisture dynamics and actual evapotranspiration fluxes. The key elements of this numerical model are the soil bucket, where rainfall, evapotranspiration and leakage drive soil moisture dynamics, and two linear reservoirs working in parallel with different characteristic response times. The surface reservoir, able to simulate the fast response of the basin, is fed by rain falling on impervious area and by runoff generated with excess of saturation …

Ricostruzione delle curve di durata mediante un nuovo approccio ecoidrologico

2012

Le curve di durata delle portate forniscono un importante sintesi dei processi idrologici più rilevanti occorrenti a scala di bacino. Sebbene vengano tipicamente ottenute a partire dalle osservazioni idrometriche, uno dei temi più rilevanti in idrologia è proprio la loro ricostruzione anche in bacini non strumentati. A tal proposito sono stati sviluppati negli ultimi anni svariati approcci teorici, alcuni dei quali meritano particolare attenzione per la loro semplicità di applicazione e accuratezza dei risultati mostrati. La curva di durata viene spesso disaggregata in due componenti: una componente veloce di deflusso superficiale ed una componente lenta di deflusso subsuperficiale. Un rece…

Modelling flows duration curves in Mediterranean river basins through an ecohydrological approach

2011

The flow duration curve, representing the relationship between magnitude and frequency of streamflows in a basin, provides an important synthesis of the relevant hydrological processes occurring at the basin scale. It is typically obtained from field observations and, since most of the geographical areas of the world still lack suitable streamflow observations, its reconstruction in ungauged river basins is certainly an open and relevant issue in the hydrological literature. Different theoretical approaches have been developed in recent years, and in particular, a novel ecohydrological framework has provided considerable results. The aim of this study is to test with field data, a recent an…

Rule of Law.Il governo della legge ieri e oggi

In questa rivisitazione della formula del rule of law s’intende mostrare che essa non deve essere ridotta all’individuazione di determinate caratteristiche formali dei precetti giuridici e neppure allargata sì da comprendere determinati contenuti normativi del diritto, ma che essa è rivolta ad indicare come deve essere praticato il diritto. L’uso del diritto è importante quanto l’individuazione dei criteri formali di validità, e forse ancor più di questi. Questa linea di pensiero è illustrata sia facendo riferimento alla tradizione filosofico-giuridica, da Aristotele a Tommaso d’Aquino, sia segnalando l’espansione della formula del rule of law anche nella filosofia politica contemporanea, e…

Ermeneutica giuridica e pluralismo

2012

The traditional theory of legal interpretation has been worked out with reference to culturally homogeneous societies and on the basis of priority of domestic law.Nowadays both of these conditions has been vanished, because of cultural and legal pluralism. In this paper I aim to show that legal hermeneutics can cope with the problems that have been risen by contemporary pluralism. The main difficulty stems from the fact that philosophical hermeneutics too seems to necessarily require a kind of cultural homogeneity and steadiness that cannot be presupposed anymore.

Basin-scale water resources assessment in a sicilian basin under climate change scenarios using the conceptual model TOPDM

2011

Climate change resulting due to the greenhouse effect is expected to have great implications for hydrological cycle and for existing surface and groundwater resources systems. The effects of climate variability and climate change have to be fully considered in current water management and planning, since water availability, quality and streamflow are very sensitive to changes in temperature and precipitation regimes. International literature proposes several models, attempting to assess accurately the available water resources under stationary and changing climatic conditions at different spatial and temporal scales. In order to assess the potential impacts of climate change on surface and …

Hydrological regime modifications induced by climate change in Mediterranean area

2015

The knowledge of river flow regimes has a capital importance for a variety of practical applications, in water resource management, including optimal and sustainable use. Hydrological regime is highly dependent on climatic factors, among which the most important is surely the precipitation, in terms of frequency, seasonal distribution and intensity of rainfall events. The streamflow frequency regime of river basins are often summarized by flow duration curves (FDCs), that offer a simple and comprehensive graphical view of the overall historical variability associated with streamflow, and characterize the ability of the basin to provide flows of various magnitudes. Climate change is likely t…

Annual runoff assessment in arid Mediterranean watersheds under the Budyko framework

2016

The solution of many practical water problems is strictly connected to the availability of reliable and widespread information about runoff. The estimation of mean annual runoff and its interannual variability for any basin over a wide region, even if ungauged, would be fundamental for both water resources assessment and planning and for water quality analysis. Starting from these premises, the main aim of this work is to show how using the Budyko framework is possible to map the mean annual surface runoff and derive the pdf of the same variable in arid watersheds. As a case study, the entire island of Sicily, Italy, is here proposed. First, time series data of annual rainfall, runoff and r…

Mapping the annual runoff data in Sicily using a geostatistical approach

2011

The availability of reliable and long time series of runoff data is fundamental for most of the hydrological analyses and for the assessment and the management of water resources even in condition of global climatic change. However, hydrologic data set are often characterized by a short duration and also suffer from missing data values, mainly due to malfunctioning of gauging stations for a specific period. In order to overcome this problem and obtain long and continuous runoff time series, different models and methods have been previously developed and proposed. While some models, used to extent the streamflow record, are conceptual, empirical, regressive models based on the rainfall input…

In particolare, l’ultima relazione sullo stato dell’ambiente europeo a cura dell’Agenzia Europea dell’Ambiente (AEA, 2010) considera l’impermeabilizzazione dei bacini naturali come uno dei maggiori processi di degrado del suolo.

EFFECTS OF DATA GAP ON THE CAPABILITY TO DETECT TREND IN HYDROCLIMATOLOGICAL TIME SERIES

2012

In the last decades the growing concerns about the existence of global climatic changes push many researchers to use different trend test in order to identify whether monotonic trends exist in hydroclimatological time series such as temperature, precipitation, and streamflow. Unfortunately, these time series often suffer from missing data values mainly due to malfunctioning of gauge for specific time periods. Starting from this premise, the main target of our work is to investigate the effect of data gap in a time series on the results provided by the most used trend test: the nonparametric Mann–Kendall statistical test. Firstly, different synthetic time series characterized by different si…

Daily rainfall statistics in Sicily (1920-2000)

2012

Rainfall characteristics are crucial for vegetation patterns formation and evolution in Mediterranean ecosystems. Changes in rainfall frequency and intensity could cause vegetation water stress for some plant species and benefit, at the same time, other species, driving coexistence and competition dynamics. The changes in the precipitation characteristics are sometimes more important than the changes in the total amount of precipitation in determining the partitioning between green and blue water with several implications for both the vegetation communities health and water resource management. Decreasing rainfall is a clear signature of climate change in Mediterranean countries. Annual and…

In riferimento a questo secondo aspetto, con il lavoro qui riportato, si è voluto indagare circa l’esistenza o meno di un trend nella durata delle stagioni e nella quantità di risorsa idrica prodotta durante le stagioni stesse. Queste in genere sono identificate con criteri legati alle cadenze mensili che tengono conto solo sommariamente dell’effettiva variazione climatica stagionale; p…

Climate changes effects on vegetation in Mediterranean areas

2009

The Mediterranean ecosystems evolved under climatic conditions characterized by precipitations markedly out of phase with the growing period for the vegetation there established. In such environments, deep and shallow rooted species cohabit and compete each other. The formers, being characterized by deeper root, are able to utilize the water stored during the dormant season, while the conditions of shallow rooted plant are closely related to the intermittence of the precipitations.
