Straining at work and its relationship with personality profiles and individual consequences in healthcare workers (HCWs)
2020
Straining is an attenuated form of mobbing, in which the continuity of vexatious actions is not driven by a discriminatory intent. With the objective of testing the possible moderating role of personality in the relationship between perceptions about straining at work and individual consequences, a correlational design research involved 374 healthcare workers (HCWs) from two Italian hospitals. The following questionnaires were administered: (1) Short Negative Acts Questionnaire (S-NAQ), to assess discriminative actions at work)

A fuzzy multi-criteria decision-making methodology to optimise olive agro-engineering processes based on geo-spatial technologies
2016
In southern Italy, the olive oil sector is an important part of the primary sector and its development requires support from research to ensure its sustainability. This work proposes the first step for set up a decision support system (DSS) for establishing mechanisation in agricultural operations for different olive groves. To contribute to this goal researches have been carried out to test the ability of remote sensing (RS) and geographic information system (GIS) to map olive groves and their agronomic characteristics. In detail, this study aimed to classify olives grove areas in terms of agronomic suitability and detect horticultural characteristics of olive groves in order to develop a …
The decline of the cork oak growing in Sicily is accompanied by the loss of the functions proper to agroforestry systems
2021
The cork oak is one of the most important tree species in the Mediterranean basin, where it covers more than 2 million hectares. Among evergreen oaks, Quercus suber stands out for the variety of cultural systems in which it has been successfully employed, including typical agroforestry systems. Accordingly, a wide range of ecosystem services may be associated to cork oak, including the preservation of biodiversity, carbon sequestration and forage production. In the Mediterranean, the cork oak represents a key species for many natural and seminatural landscapes and habitats, as well as playing a prominent role for the economic and social development of local communities. However, there is in…
Le trasformazioni urbane di Agrigento dai primi decenni del XX secolo agli anni della speculazione edilizia
2018
Come mostra una lunga tradizione di studi di storia urbana, i Catasti storici di un tipo geometrico descrittivo sono oggi proposti come rappresentazioni affidabili di una reale condizione dei luoghi in un determinato momento storico. Nel caso della città di Agrigento, lo studio del Catasto redatto nei primi anni trenta del Novecento, opportunamente supportato dall'aiuto di altre fonti, è la linea di partenza di un itinerario ricostruttivo delle trasformazioni più rilevanti del periodo post-bellico che modificheranno pesantemente la struttura urbana della città, facendo di Agrigento un caso di studio emblematico di quella che era, più in generale, la grave situazione urbanistica dell'intero …
Agrigento: identità e trasformazioni del paesaggio tra risorse e degrado
2012
Nell’immaginario collettivo la città di Agrigento è inscindibilmente legata al patrimonio archeologico della Valle dei Templi. Ma l’immagine di Agrigento è anche quella dell’abusivismo edilizio che dilaga nel territorio circostante addensandosi lungo la linea di costa, nonché quella del suo straordinario centro storico, degradato e in abbandono, ormai assediato dagli imponenti volumi edilizi, prodotto della speculazione edilizia degli anni ’50 e ‘60, e circondato da strade e viadotti. Nel riconoscere il paesaggio come risorsa identitaria, collegando quindi la nozione di identità a quella di memoria, di storia e di cultura, deve essere implicita un’ulteriore operazione che è quella di proiet…
Abitare ad Agrigentum: riletture in corso dell’isolato II del Quartiere ellenistico-romano
2020
Si illustrano brevemente le problematiche attuali dell'indagine sul cd. Quartiere ellenistico-romano di Agrigento, focalizzando l'attenzione sull'isolato II. The current problems of the investigation into the Hellenistic-Roman district of Agrigento are briefly illustrated, focusing attention on block II.
Detecting crop water requirement indicators in irrigated agroecosystems from soil water content profiles: An application for a citrus orchard.
2022
Abstract Most perennial crops sensitive to water scarcity, such as citrus, can benefit from efficient water management, which allows for reduced water consumption while increasing crop production on a long-term basis. However, when implementing water-saving strategies, it is necessary to monitor soil and/or plant water status in order to determine crop water demand. A plethora of devices providing indirect measurements of volumetric soil water content, such as the “drill and drop” multi-sensors probes (Sentek, Inc., Stepney, Australia), have been developed over the last decade. The objective of the paper was to analyse time-series of soil water content profiles and meteorological data colle…
Cover crop management and water conservation in vineyard and olive orchards
2021
Abstract Sustainability in orchard crops is an important goal for farmers, decision-makers and consumers. The United Nations Sustainable Development Goals emphasize the importance of the soils in the Earth System to achieve sustainability and accomplish the Land Degradation Neutrality Challenge. Within the world agriculture land, olive and vineyards are within the eldest crops in the world, and they are also the ones with the highest degree of soil degradation. Cover crops (CC) are widely accepted as sustainable crop management that reduces soil and water losses, restores organic matter, increases biodiversity and fertility in degraded agriculture soils. The agriculture land must shift into…
