Decentralization and the Welfare State: What Do Citizens Perceive?

Trust in public institutions and public policies are generally perceived as a precondition for economic recovery in times of recession. Recent empirical evidence tends to find a positive link between decentralization and trust. But our knowledge about whether decentralization – through increased trust – improves the perception of the delivery and effectiveness of public policies is still limited. In this paper we estimate the impact of fiscal and political decentralization on the perception of the state of the education system and of health services, by using the 2002, 2004, 2006 and 2008 waves of the European social survey. The analysis of the views of 160,000 individuals in 31 European countries indicates that while the effect of fiscal decentralization on the perception of the state of the health and education system is limited, political decentralization clearly affects citizen’s satisfaction with education and health delivery. The influence of political decentralization, however, is highly contingent on whether we consider the capacity of the local or regional government to exercise authority over its citizens (self-rule) or to influence policy at the national level (shared-rule).

Sea state effect on the sea surface emissivity at L-band

In May 1999, the European Space Agency (ESA) selected the Earth Explorer Opportunity Soil Moisture and Ocean Salinity (SMOS) mission to obtain global and frequent soil moisture and ocean salinity maps. SMOS' single payload is the Microwave Imaging Radiometer by Aperture Synthesis (MIRAS), an L-band two-dimensional aperture synthesis radiometer with multiangular observation capabilities. At L-band, the brightness temperature sensitivity to the sea surface salinity (SSS) is low, approximately 0.5 K/psu at 20/spl deg/C, decreasing to 0.25 K/psu at 0/spl deg/C, comparable to that to the wind speed /spl sim/0.2 K/(m/s) at nadir. However, at a given time, the sea state does not depend only on local winds, but on the local wind history and the presence of waves traveling from far distances. The Wind and Salinity Experiment (WISE) 2000 and 2001 campaigns were sponsored by ESA to determine the impact of oceanographic and atmospheric variables on the L-band brightness temperature at vertical and horizontal polarizations. This paper presents the results of the analysis of three nonstationary sea state conditions: growing and decreasing sea, and the presence of swell. Measured sea surface spectra are compared with the theoretical ones, computed using the instantaneous wind speed. Differences can be minimized using an "effective wind speed" that makes the theoretical spectrum best match the measured one. The impact on the predicted brightness temperatures is then assessed using the small slope approximation/small perturbation method (SSA/SPM).
