28 p, 705.0 KB On the production of cognitive achievement and gaps in test scores / Creel, Michael (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica) ; Farell Ferrer, Montserrat (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica)
We investigate the accumulation of cognitive achievement using an indirect production function, estimated using a flexible, dynamic econometric model and a new, rich data set. Gaps between black and white children remain constant, narrow, or disappear entirely as children grow older, depending upon the achievement measure and the family structure. [...]

4 p, 1.7 MB Differential microstrip lines with common-mode suppression based on electromagnetic band-gaps (EBGs) / Vélez Rasero, Paris (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; Bonache Albacete, Jordi (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; Martín, Ferran, (Martín Antolín) (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica)
A technique for the suppression of the common mode in differential (balanced) microstrip lines, based on electromagnetic band-gaps (EBGs), is presented in this letter. It is demonstrated that by periodically modulating the common-mode characteristic impedance of the line and simultaneously forcing the differential-mode impedance to be uniform (and equal to the reference impedance of the differential ports), the common mode can be efficiently suppressed over a certain frequency band, while the line is transparent for the differential-mode.

60 p, 641.6 KB Reassessing global change research priorities in mediterranean terrestrial ecosystems : how far have we come and where do we go from here? / Doblas Miranda, Enrique (Centre de Recerca Ecològica i Aplicacions Forestals) ; Retana Alumbreros, Javier (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Aim: Mediterranean terrestrial ecosystems serve as reference laboratories for the investigation of global change because of their transitional climate, the high spatiotemporal variability of their environmental conditions, a rich and unique biodiversity and a wide range of socio-economic conditions.

16 p, 103.9 KB Optimal Gaps in Optimal Paradigms / Rice, Curt (University of Tromsø)
This article develops a treatment of phonologically motivated gaps in paradigms within Optimal Paradigms Theory (McCarthy 2001). The gaps are instances of absolute ungrammaticality, i. e. situations in which there is no output for a given input. [...]

20 p, 190.0 KB D6.1. ConnectinGEO methodology / Masó Pau, Joan (Centre de Recerca Ecològica i Aplicacions Forestals) ; CONNECTINGEO
Describing the ConnectinGEO methodology to be developed and tested during the project and to be promoted beyond the end of it.
The main aim of the ConnectinGEO methodology is to find gaps in EO networks and systems (mainly in-situ or non-space), determine remedies and recommendpriorities to solve these gaps. The gap analysis phase follows five different threads: Top-Down thread 1: Identification of a collection of observation requirements Top-Down thread 2: Research programs aims and targets Bottom-up thread 1: Consultation process Bottom-up thread 2: GEOSS Discovery and Access Broker analysis Bottom-up thread 3: industry-driven challenges. [...]
Then, a period for reviewing the gaps and identifying remedies will start. The quantifications of the impact, the feasibility and the costs will permit the application of a semi automatic priority calculation. [...]
