Children's exploration of the concepts of home and belonging: Capturing views from five European countries.
2021
Understanding one's sense of belonging is a central part of identity formation and self-awareness; feeling safe somewhere, with specific people is identified as a basic human need. This paper explores the ideas of children from three age groups in five different European as they discussed the concepts of ‘home’ and ‘belonging’. Findings showed that the children's ideas could be organised into six interrelated aspects: Spatiality, Materiality, Multiplicity, Social Relations, Affect, and Dislocation. Whilst there were differences in the ways that the children conceptualised home across the classes, even the youngest children were able to describe their ideas using metaphors and abstract conce…
Interlake variation and environmental controls of denitrification across different geographical scales
2013
Denitrification in lakes significantly reduces the nitrogen (N) load from land to oceans, but the factors controlling it remain poorly under- stood. Therefore, interlake variation of denitrification in sediments of small to medium-sized lakes (from 0.03 to 17.8 km 2 ) was studied across different geo- graphical scales. At the local scale, the denitrification rates and sediment microbial communities were studied in 4 boreal lakes in close proximity (within 20 km) using the isotope pairing technique (IPT) and molecular methods. These local scale data were com- bined with previously published data on denitrifica- tion rates from 10 other European lakes to extend the analysis to the regional (b…
Migrazione e variazione diatopica, mobilità e cambio linguistico. Premesse allo studio delle varietà italoalbanesi
2022
For the Italo-Albanian reality, the diatopic-diachronic relationship of dialect variation takes on different aspects compared to that experienced in the Italo-Romance reality. This is due to the fact that the linguistic-geographical dislocation (prior and subsequent to the diaspora) and the diachronic distribution of the various migratory stages, have produced historical and territorial discontinuity of the archipelagos and of the Arbëreshë islands variously distributed in the Italo-Romance continuum. In addition to this differential factor between the order of dialectological studies of the Italo-Romance sphere and those relating to the Italo-Albanian reality, other problematic relationshi…
The Diversification of Sicilian Farms: A Way to Sustainable Rural Development
2021
Rural areas still suffer from a lack of sustainable development, and the diversification of farms may be a step in the right direction. The paper provides a detailed picture of the diversification of Sicilian farms into tourism services. Specifically, we propose a simple indicator of localization intensity of agritourism farms and explore their spatial distribution at municipality level. Our study highlights that Sicilian farms rarely diversify into tourism services, despite being situated in attractive areas. That said, some significant spatial clusters of municipalities where agritourism farms are highly concentrated do emerge from the study.
Economic specialization and diversification at the country and regional level: introducing a conceptual framework to study innovation policy logics
2018
While there has been a shared understanding that innovation policy is about rendering institutional change, there has been an emerging interest in identifying the institutional logics underlying in...
Geomatic applications tourban park in palermo
2015
Over the last few years topographical techniques have developed an exponential trend towards simplifying and speeding, both survey operations and analysis of data collected reaching at the same time ever higher levels of accuracy. Among the technologies that are increasingly taking the field in this context is part of the Mobile Mapping System (MMS) that, on any mobile platform, combines sensors and measurement systems designed to provide a 3D position of the platform and, at the same time, capable to acquire geographic data without the aid of control points on the ground. The study reported concerns the verification of the reliability metrics and a qualitative MMS in order to evaluate its …
Factors controlling hydrochemical and trophic state variables in 86 shallow lakes in Europe
2003
In order to disentangle the causes of variations in water chemistry among European shallow lakes, we performed standardised sampling programs in 86 lakes along a latitudinal gradient from southern Spain to northern Sweden. Lakes with an area of 0.1 to 27 000 ha and mean depth of 0.4–5.6 m located in low to high altitudes were investigated within the EC project ECOFRAME 1–4 times during June–October 2000–2001. Several variables like conductivity, alkalinity, abundance of submerged plants, concentrations of suspended solids, total nitrogen and phosphorus were latitude-dependent decreasing from south to north. Secchi depth, concentrations of total nitrogen, total phosphorus, suspended solids, …
Exploring the sources of labour productivity growth and convergence in the Italian regions: some evidence from a production frontier approach
2009
This paper investigates labour productivity growth and regional convergence patterns in Italy over the time span 1982–2000. Starting from some evidence of spatial polarisation within Italian economy, the analysis aims at exploring the sources of this tendency. To this end, an approach based on data envelopment analysis (DEA) production frontiers is employed which allows to decompose labour productivity growth into efficiency change, technological progress and capital deepening, looking then at the relative contribution of each component to regional convergence. Moreover, some measures of human capital and public capital are used as augmentation factors of the conventional inputs. The study …
Informational interactions and the future of cities
1998
Present-day city growth is chiefly the result of new tertiary activities such as financial and producer services, R&D, or business administration. It seems that these activities need to be more spatially concentrated than traditional manufacturing activities. These new trends affect both the structure of cities and the structure of city systems. The specific nature of the new activities concentrated in city centers makes them information intensive. These activities consume human capital, knowledge and hightech capital, which are all rapidly changing inputs; they are based on complex decisionmakingprocesses; this renders them highly information-dependent. Inasmuch as these activities are the…
