Polycentric Metropolitan Areas in Europe: Towards a Unified Proposal of Delimitation
2012
Metropolitan areas concentrate the main share of population, production, and consumption in developed countries. They are likely to be the most important units for economic, social, and environmental analysis as well as for the development of policy strategies.
Controlling Thermal Flows through Natural Materials in Building Construction Sector
2019
Nowadays, the attention about the building sustainability is increasingly emerging, because of the major responsibility of the building field on the environmental degradation: both in terms of energy consumption from non-renewable sources and the raw materials impoverishment. In addition, the level of comfort required by users is growing and the thermal insulation of buildings becomes the key element for the reduction of energy consumption and CO2 emissions, both in the case of new construction and of the existing ones. The heat load of a building depends on the presence of insulating material which defines the performance of the building envelope. The main purpose of this work is both to i…
Quantitative View on the Processes Governing the Upscale Error Growth up to the Planetary Scale Using a Stochastic Convection Scheme
2019
Abstract Two diagnostics based on potential vorticity and the envelope of Rossby waves are used to investigate upscale error growth from a dynamical perspective. The diagnostics are applied to several cases of global, real-case ensemble simulations, in which the only difference between the ensemble members lies in the random seed of the stochastic convection scheme. Based on a tendency equation for the enstrophy error, the relative importance of individual processes to enstrophy-error growth near the tropopause is quantified. After the enstrophy error is saturated on the synoptic scale, the envelope diagnostic is used to investigate error growth up to the planetary scale. The diagnostics re…
Investigating technical and pedagogical usability issues of collaborative learning with wikis
2012
Published version of an article in the journal: Informatics in Education : an International Journal. Wikis have been recently promoted as tools that foster collaborative learning. However, there has been little research devoted to the criteria that are suitable to address issues pertinent to collaborative learning. This paper proposes a set of criteria to explore technical and pedagogical usability issues of collaborative learning with wikis. The criteria are then used to evaluate students’ collaborative writing activities. The units of study are wikis that groups of students developed collaboratively using MediaWiki. This paper also reports on technical and pedagogical implications for the…
Designing and evaluating collaboration in a virtual game environment for vocational learning
2008
Especially in vocational education, attention should be paid not only to the use of new technological solutions but also to collaborative learning and cooperative working methods in order to develop students' skills for their future jobs. This study involves a design experiment including the design process of a new game environment, description of the script developed for this game, as well as the empirical study with multiple data collection methods, data analysis, results and conclusions for further work. The aim of the study was twofold. Firstly, we aimed to develop a game environment to simulate the work context of a vocational design process, and secondly, to investigate how effective …
Organisation and Efficiency of Education Systems: Some empirical findings
2000
Using a sample of countries chosen for their similar level of development, this article shows the extent to which the organisation of primary and secondary education differs from one country to another, notably with respect to the way in which systems differentiate and select pupils for specialised curricula. It also explores the question of whether an education system that sorts pupils at a very early age is more cost-effective than a system that does not sort pupils during compulsory education. The stylised description of national education systems is based on various sources of information. The data used in the cost analysis come from the Organisation for Economic Co-operation and Develo…
A Km-scale Cretaceous slope in western Sicily (Italy)
2017
Cretaceous slopes are well known from many regions of the world, since they are among the most prone depositional systems to host hydrocarbons. As far as Italy, in spite of fully described examples as the Majella and Gargano escarpments, detailed sedimentological and biostratigraphic studies from Sicily are not available, although the presence of slope carbonates of Cretaceous age in northwestern Sicily, is mentioned in several papers dealing with regional geology or geological mapping. The Cretaceous slope carbonates from this area, i.e. the San Vito Lo Capo Peninsula, belong to several thrust sheets of the Maghrebian chain. The stratigraphic setting in these tectonic units allows to recon…
Out of sight : Profiling soil characteristics, nutrients and bacterial communities affected by organic amendments down to one meter in a long-term ma…
2019
Common soil characteristics, nutrients and microbial activity at deeper soil depths are topics seldom covered in agricultural studies. Biogeochemical cycles in deep soils are not yet fully understood. This study investigates the effect of different mineral and organic fertilisation on soil organic matter dynamics, nutrients and bacterial community composition in the first meter of the soil profiles in the long-term maize cropping system experiment Tetto Frati, near the Po River in northern Italy. The following treatments have been applied since 1992: 1) crop residue removal (CRR), 2) crop residue incorporation (CRI), 3) crop residue removal with bovine slurry fertilisation (SLU), 4) crop re…
Mutual intelligibility among the sign languages of Belgium and the Netherlands
2015
AbstractIn an exploratory study of mutual intelligibility between the sign languages of the northern part of Belgium (Flemish Sign Language, VGT), the southern part of Belgium (French Belgian Sign Language, LSFB), and the Netherlands (Sign Language of the Netherlands, NGT), we tested the comprehension of VGT by signers of LSFB and NGT. In order to measure the influence of iconic structures (classifier constructions and constructed action) that linguistic analyses have shown to be similar across different sign languages, two genres were compared: narrative and informative signing. To investigate the effect of the overlap between the spoken languages surrounding the Dutch and Flemish Deaf com…
Structure of mammalian plasma fetuin-B and its mechanism of selective metallopeptidase inhibition
2018
The co-crystal structure of the metallopeptidase astacin with its specific protein inhibitor fetuin-B reveals a novel mechanism of inhibition.
