In June 2010, European Union (EU) Heads of State and Government adopted a social inclusion target as part of the new 'Europe 2020 Strategy': to lift at least 20 million people in the EU from the risk of poverty and exclusion by 2020. One of the three indicators used to monitor progress towards this target is the EU indicator of severe material deprivation (MD). A main limitation of this indicator is the weak reliability of some of the items it is based on. For this reason, a thematic module on MD was included in the 2009 wave of the EU Statistics on Income and Living Conditions (EU-SILC) survey. This article assesses the 2009 EU-SILC MD data and proposes an analytical framework for developing robust EU MD indicators. It carries out a systematic item by item analysis at both EU and country levels to identify the MD items which satisfactorily meet suitability, validity, reliability and additivity criteria across the EU. This approach has resulted in a proposed 13-item MD indicator covering some key aspects of living conditions which are customary across the whole EU covering a broad range of basic (food, clothes, shoes, etc.) as well as social (Internet, regular leisure activities, etc.) necessities.

The authors conclude that a revitalized - and refocused - development program should concentrate on the goals of broad-based economic growth, the alleviation of poverty, and a halt to environmental degradation, all of which would require dramatic changes in U.S. economic, trade, and foreign aid policies

Currently, this is realized mainly in 2D materials characterized by circular Fermi surfaces. Here we demonstrate that the nearly perfectly hexagonal Fermi surface of PdCoO2 gives rise to highly directional ballistic transport. We probe this directional ballistic regime in a single crystal of PdCoO2 by use of focused ion beam (FIB) micro-machining, defining crystalline ballistic circuits with features as small as 250 nm. The peculiar hexagonal Fermi surface naturally leads to enhanced electron self-focusing effects in a magnetic field compared to circular Fermi surfaces. This super-geometric focusing can be quantitatively predicted for arbitrary device geometry, based on the hexagonal cyclotron orbits appearing in this material. These results suggest a novel class of ballistic electronic devices exploiting the unique transport characteristics of strongly faceted Fermi surfaces. ; Publisher PDF ; Peer reviewed
