Rewards, changes and challenges in the role of primary headteachers/principals in England and Finland
2012
Drawing on an analysis of education policies and qualitative research data, the impact of education reform on the roles of English primary headteachers and their Finnish counterparts is examined and compared. Global forces have resulted in similar policy trends in both countries but owing to contrasting cultural values and education traditions there are marked differences in the mechanisms for change at both national and local levels. However, irrespective of globalisation and differing national contexts, there were considerable similarities in the perspectives of headteachers and principals on the rewards and constraints of their role and the realities of leadership and management.
Estimation of Role of Sicilian Region on Production of Quality Wines. A Comparison between the Best Sicilian and Italian Wines by Using Influential W…
2016
Abstract Sicilian region (Southern Italy) has always been the larger Italian wine producer, because of their terroir (i.e. climate, soil and cultivar) and the extension of the vineyard area. For a long time, in the past, Sicilian vineyards produced only wine for blending or for bulk wine consumption. However, the quality of wine production in the Sicilian region has raised significantly over the past years, due to numerous factors, including, primarily, the development of manufacturing techniques, the major business investments of wineries, and the better legislation for protection of quality wines. These factors, combined with producers' targeted marketing strategies and actions, have grea…
Functionalized Halloysite for enhanced removal of toxic metal ions from aqueous solutions
2018
During the last years several nanomaterials have been extensively used in the heavy metal ions removal from aqueous solutions. Among them, clay minerals have gathered particular interest owing to their unique features (e.g., high specific surface area, low toxicity and natural availability at low price). Halloysite nanotubes (Hal) are particular clay minerals with a predominantly hollow tubular structure. In this work Hal and their derivatives, Hal-NH2 and Hal-SH, were used as adsorbent materials of lead(II) and mercury(II) ions from aqueous solutions. The adsorption ability of clay nanomaterials towards toxic metal ions has been studied takeing into account important variables of the metal…
Relevant figures / Figures in relief
2011
The identification, within the contemporary scenario of communication design, of those figures who have reached a level of excellence (due to professional itineraries, researches, experiments), is not a simple task: the difficulty is not knowing who these figures are, but the responsibility of offering, in a context such as Aiap Design Per, relevant personalities as well as a high level in the various workshops, where many areas of our disciplines are tackled, from typography to editorial design and graphic design for cultural goals. Riuscire a individuare nello scenario contemporaneo del design della comunicazione quelle figure che per percorsi professionali, ricerche, sperimentazioni, si …

Relaciones de género entre los Wayuu. Estado de la investigación y nuevos campos de análisis
2006
L'articolo esamina le relazioni di genere tra i Wayuu della Colombia. Vengono esaminati i rapporti tra genere, discendenza matrilineare e gerarchie di status basate sulla ricchezza. La posizione delle donne è trattata sia in riferimento all'organizzazione sociale, sia nelle guerre interne, sia a livello simbolico, tanto nella mitologia che nei rituali. Il ruolo di interfaccia tra interno ed esterno del sè collettivo giocato dalle donne si esprime tra i Wayuu in particolare nel loro ruolo preponderante come sciamene che in quello di rappresentanti del gruppo nelle negoziazioni con le istituzioni non indigene
