Efficienza, qualità ed equità dei sistemi di welfare regionali: un confronto tra i modelli di governance
No full textQuesto saggio si pone l’obiettivo di esaminare se esista o meno uno specifico modello di governance della sanità – il principale sistema di welfare gestito in Italia a livello regionale – che meglio consenta di raggiungere gli obiettivi di efficienza, qualità, equità, efficacia e sostenibilità finanziaria e sociale. Oggetto di analisi sono i principali modelli di governance che storicamente si sono sviluppati nel campo della sanità. Il sistema sanitario italiano, dopo le riforme degli anni ‘90, si è caratterizzato per un’introduzione degli elementi della logica del quasi-mercato molto diversificata da parte delle diverse regioni. Si sono così sviluppati almeno quattro diversi modelli di governance regionale della sanità: modello a centralità Asl, modello a completa separazione acquirente-produttore, modello a centralità regionale, modello di transizione. I due modelli di governance più maturi appaiono quello a centralità Asl (es. Emilia Romagna) e quello a completa separazione acquirente/produttore (Lombardia), entrambi con punti di forza e di debolezza. Si evidenzia inoltre il ruolo positivo che può essere svolto dalla mobilità inter-regionale nell’incentivare le regioni a migliorare la qualità dei propri sistemi sanitari. A prescindere dai modelli di governo regionale, il buon funzionamento della logica di quasi-mercato necessita del governo sia dell’offerta di servizi sanitari (pianificazione di strutture, servizi e produzione in base ai bisogni dei residenti, vincoli di bilancio, indicatori, livelli essenziali di assistenza) sia della domanda (orientare la domanda verso forme appropriate di assistenza, con un ruolo attivo svolto dal medico di medicina generale)

Micro-Raman investigation of p-type B doped Si(1 0 0) revisited
No full textThe doping concentration of B doped single-crystal Czochralski Si(1 0 0) wafers (6 × 1014-5 × 1019 cm−3) has been monitored via micro-Raman spectroscopy using visible (633 and 532 nm) and near-UV (355 nm) laser excitations at low power (5 mW). Data have been analysed with unprecedented accuracy via a convoluted Fano-Gaussian model of the first-order Raman Stokes mode of Silicon. This allowed the determination of the fitting spectral parameters (peak position and width) with an accuracy of 0.01 cm−1, which enables a reliable probing of the concentration. We observed, independently on the excitation wavelength used, a widening (up to 6.5 cm−1), a frequency-softening (up to 1.5 cm−1) and an intensity reduction (down to 90%) of the Si peak with the doping concentration. The widening and frequency-softening follow a strictly linear dependence with doping concentration, allowing a calibration. A linear dependence of the reciprocal Fano asymmetry parameter (q-1) with excitation energy is verified, with the slope showing a linear behavior with the doping concentration and providing a direct estimate on the hole-phonon interaction strength. Results are reproduced with surface-sensitive near-UV Raman spectroscopy on BF2+ ion implanted and laser thermal annealed (LTA) Si, demonstrating the full portability of the Raman technique to state-of-the-art nanoelectronics
Defining the time and spatial scale of climate response to CO2 changes
No full textThe goal of this research is to investigate the response of climate system to both temporal and spatial variations in the atmospheric carbon dioxide concentration. In the first part the response function of the atmosphere has been defined and the typical time scale involved in the fast response of the system to variations in the CO2 forcing has been evaluated. In the second part the effects of a set of localized and stationary anomalies of CO2 concentration on the state of the atmosphere have been detected with a set of GCM experiments, and further investigated with a set of linearized experiments. In order to perform these linearized experiments, a new linear version of the Eulerian Dynamical Core of CAM (Community Atmosphere Model) has been proposed. The linearized experiments have allowed to assess which forcing region, among the ones considered, is particularly effective in terms of both amplitude and spatial extent of the response
Societal institutions and contradictions in the workplace: A comparative analysis of lean management systems in Germany, Italy, and the United Kingdom
No full textThis article combines insights from the organizational institutionalist (OI) literature on the complexity of transnational institutional streams and the power-based approach of the comparative employment relations (CER) literature to better explain diversity in human resource (HR) practices across organizations embedded in different societal contexts. Building on the insights from both literature strands, the article argues that societal institutions, by providing power resources to labour vis-a-vis management, influence the settlement of contradictions in HR practices in the workplace, with implications for the internal consistency of HR systems. The findings are based on the comparative case study of three metal companies in Germany, Italy and the United Kingdom that implemented lean management systems. They suggest that labour-supporting institutions at the sectoral and organizational levels in the German metal company contribute to a more ‘balanced’ settlement of the tensions between the (ideo)logics of empowerment, cost-cutting and Taylorism, which characterize lean management systems, compared to the Italian and British companies. The article contributes to cross-fertilization between the OI and CER literature because it demonstrates the value of integrating the power resource perspective in (comparative) OI studies, and of taking into greater consideration the role of transnational (ideo)logics in CER research.</p

Active vibration isolation using an inertial actuator with local feedback control
No full textThe design of inertial actuators with local force feedback control and their use in active vibration isolation systems is considered. Unlike reactive actuators, inertial actuators do not need to react off a base structure and can therefore be directly installed on a vibrating structure. In order to guarantee good stability margins in the active isolation controller, however, the actuator resonance must have a low natural frequency and it must be well damped.The behaviour of an inertial actuator with different local force feedback control schemes is first analysed, and it is shown that a phase-lag controller has a good stability margin and can effectively damp the actuator resonance using relatively low gains, compared with a direct force feedback or integrated force feedback controller.A frequency-domain formulation is then used to analyse the stability and performance of an active isolation system using an inertial actuator with local force feedback control and an outer velocity feedback control loop. The plant response, from force actuator input to sensor output, is derived in terms of the mechanical mobilities of the equipment structure being isolated and the vibrating base structure, and the mechanical impedance of the intervening mount.An experimental study of active vibration isolation using an inertial actuator with local feedback control was then carried out. Theory and experiments agree well, demonstrating the effectiveness of the phase-lag controller. However, the need to have an inertial actuator with a low resonance frequency leads to problems with static deflections
