Article 41 of the Italian Constitution and the Italian Model of Corporate Social Responsibility

Article 41 of the Italian Constitution is composed of three important provisions: the first one establishes the principle of free economic activity, the second one is about its limitations while the third one sets out the way public intervention – seen as necessary to the direction and co-ordination of economic activity – may take place. A proposal for reforming is possible in the new economy to achieve a CSR model.Italian constitution; social responsibility; private economic; CSR model..

Short Notes about Financial Reporting in Italian Family Businesses

The main purpose of the paper is to analyse some features regarding economic and financial communication in Italian family companies. This is a theoretical essay focuses on to point out the new role played by balance sheet as a public document which carries all information needed by players operating both inside and outside the company. Paper shows the long and troubled process of transforming balance sheet from internal document to an official document useful to stakeholder to measure and evaluate family business performance and to implement accountable and responsible behaviour. The most important aspects being considered are: 1) the relationship link-ing balance sheet and stakeholders; 2) the relationship between company-family and patrimony-marriage; 3) the consequences caused to the balance sheet by measurement regulations.family business; balance sheet; accountability; financial reporting; firm behaviour; stakeholders.

Velocity shear, turbulent saturation, and steep plasma gradients in the scrape-off layer of inner-wall limited tokamaks

The narrow power decay-length ($\lambda_q$), recently found in the scrape-off layer (SOL) of inner-wall limited (IWL) discharges in tokamaks, is studied using 3D, flux-driven, global two-fluid turbulence simulations. The formation of the steep plasma profiles measured is found to arise due to radially sheared $\vec{E}\times\vec{B}$ poloidal flows. A complex interaction between sheared flows and outflowing plasma currents regulates the turbulent saturation, determining the transport levels. We quantify the effects of sheared flows, obtaining theoretical estimates in agreement with our non-linear simulations. Analytical calculations suggest that the IWL $\lambda_q$ is roughly equal to the turbulent correlation length.Comment: 5 pages, 5 figure

WAGE STRUCTURE, INEQUALITY AND SKILL-BIASED CHANGE: IS ITALY AN OUTLIER?

This paper investigates the relation between wage structure, inequality and skill-biased change in Italy between 1993 and 2004. Using a quantile decomposition analysis, we point out that changes in wage structure are mainly driven by the negative coefficients component, which represents also one of driving force of the trends of wage inequality. This evidence suggests that the changes in wage structure in Italy can hardly be explained referring to a skill-biased change explanation. Evidence that is further reinforced by a set of descriptive statistics showing that the increasing educational attainments of the workforce might have been crowded out by a stable trend in the demand for skills.Educational wage premia, Human Capital, Skill Biased Change, Quantile regression, Wage Decomposition, Italy

Appl Spectrosc

Airborne silica dust (quartz) is common in coal mines and represents a respiratory hazard that can lead to silicosis, a potentially fatal lung disease. With an eye toward developing a portable monitoring device for rapid analysis of silica dust, laser-induced breakdown spectroscopy (LIBS) was used to quantify quartz in coal dust samples collected on filter media. Pure silica (Min-U-Sil\ue2\u201e\ua2 5), Georgia kaolin, and Pittsburgh-4 and Illinois-6 coal dusts were deposited separately and at multiple mass loadings onto 37-mm polyvinylchloride (PVC) filters. LIBS-generated silicon emission was monitored at 288.16 nm, and non-silica contributions to that signal from kaolinite were removed by simultaneously detecting aluminum. Measurements of the four samples were used to calculate limits of detection (LOD) for silicon and aluminum of approximately 0.08 \uce\ubcg/cm(2) and 0.05 \uce\ubcg/cm(2), respectively (corresponding to 0.16 \uce\ubcg/cm(2) and 0.20 \uce\ubcg/cm(2) for silica and kaolinite, respectively). Relative errors of prediction are around 10%. Results demonstrate that LIBS can dependably quantify silica on filter samples of coal dust and confirm that accurate quantification can be achieved for very lightly loaded samples, which supports the potential application of LIBS for rapid, in-field monitoring.CC999999/Intramural CDC HHS/United States2015-12-23T00:00:00Z23146184PMC468962

Unemployment and productivity in the long run: The role of macroeconomic volatility

We propose a theory of low-frequency movements in unemployment based on asymmetric real wage rigidities. The theory generates two main predictions: long-run unemployment increases with (i) a fall in long-run productivity growth and (ii) a rise in the variance of productivity growth. Evidence based on U.S. time series and on an international panel strongly supports these predictions. The empirical specifications featuring the variance of productivity growth can account for two U.S. episodes which a linear model based only on long-run productivity growth cannot fully explain. These are the decline in long-run unemployment over the 1980s and its rise during the late 2000s.unemployment, productivity growth, volatility

Unemployment and productivity in long-run: the role of macroeconomic volatility

We propose a theory of low-frequency movements in unemployment based on downward real wage rigidities. The theory generates two main predictions: long-run unemployment increases with (i) a fall in long-run productivity growth and (ii) a rise in the variance of productivity growth. Evidence based on U.S. time series and on an international panel strongly supports these predictions. The empirical specifications featuring the variance of productivity growth can account for two U.S. episodes which a linear model based only on long-run productivity growth cannot fully explain. These are the decline in long-run unemployment over the 1980s and its rise during the late 2000s.Unemployment, Productivity growth, Volatility

Investigation of turbulent transport regimes in the tokamak edge by using two-fluid simulations

The results of flux-driven, two-fluid simulations in single-null configurations are used to investigate the processes determining the turbulent transport in the tokamak edge. Three turbulent transport regimes are identified: (i) a developed transport regime with turbulence driven by an interchange instability, which shares a number of features with the standard L-mode of tokamak operation, (ii) a suppressed transport regime, characterized by a higher value of the energy confinement time, low-amplitude relative fluctuations driven by a Kelvin-Helmholtz instability, a strong E x B sheared flow, and the formation of a transport barrier, which recalls the H-mode, and (iii) a degraded confinement regime, characterized by a catastrophically large interchange-driven turbulent transport, which reminds the crossing of the Greenwald density limit.We derive an analytical expression of the pressure gradient length in the three regimes. The transition from the developed to the suppressed transport regime is obtained by increasing the heat source or decreasing the collisionality and vice versa for the transition from the developed transport regime to the degraded confinement regime. An analytical expression of the power threshold to access the suppressed transport regime, linked to the power threshold for H-mode access, as well as the maximum density achievable before entering the degraded confinement regime, related to the Greenwald density, are also derived. The experimental dependencies of the power threshold for H-mode access on density, tokamak major radius, and isotope mass are retrieved. The analytical estimate of the density limit contains the correct dependence on the plasma current and on the tokamak minor radius
