Tassonomia integrata per lo studio della biodiversità vegetale
2010
Diversi marcatori plastidiali sono stati testati su varie specie della flora vascolare spontanea al fine di valutarne il potere discriminante come DNA barcoding, da integrare nell'identificazione tassonomica con i dati morfologici, cariologici, fenologici e biogeografici.

Vascular flora evolution in the Soqotra Archipelago (Indian Ocean)
2012
The main floristic and vegetational features of the Soqotra Archipelago are outlined. The theories of vicariance and dispersal are commented with the support of examples suggesting the idea that both are complementary in the establishment and evolution of the flora of Soqotra. Finally the relation of alien vs natural elements of the flora is analyzed.
Biodiversity and evolution of the dendroflora in the Mediterranean
2012
The main old representatives of the Mediterranean dendroflora, their origin and distribution are treated. Relevant threats and strategy for in situ and ex situ conservation are also discussed here.
Geophytes and evolution in the Sicilian Archipelago
2012
Geophytes occurring in the Sicilian archipelago are examined with respect to their distribution and evolution, and also taking into account correlations with the inner parts of this territory and other regions in the central Mediterranean.
BIOMONITORIG ACTIVITIES OF “COMPRENSORIO DI PACE DEL MELA”.ANALYSES OF AIR QUALITY DATA
2007
The “Assessorato Territorio e Ambiente” of the Regional Sicilian Government and the “Ingegneria e Tecnologie Agro Forestali” (ITAF) Department, Palermo University, have been involved in a study (D.R.S. N° 473) concerning the occurrence of environmental pollution by heavy metals in the "Comprensorio territoriale di Pace del Mela". The involved local administrations (“comuni”) in the area of interest are: Condrò, Gualtieri Sicaminò, Milazzo, Pace del Mela, S.Filippo del Mela, Santa Lucia del Mela, San Pier Niceto. Naturalistic aspects and landscape relevance of the “Pace del Mela” area is supported by the existence of three Natural Reserves, twelve Sites of Community Interest (S.I.C.) and a Z…
Evaluating the effect of organization and context on technical efficiency: a second-stage DEA analysis of Italian hospitals
2022
Objective: the purpose of this study was to compare the technical efficiency of Italian hospitals at a regional level and to examine if differences could be explained by organisational and contextual factors. Technical efficiency was defined as the ability of the operating units evaluated to use optimal resource levels for their level of output.Methods: the effect of external factors was explored through a second stage Data Envelopment Analysis (DEA). Efficiency scores were calculated for each hospital using the DEA method (Stage I). Through Tobit regression analysis, the estimated efficiency scores were regressed against a set of organisational and contextual characteristics beyond manager…
Six Sigma in small- and medium-sized enterprises: a Black Belt project in the Swedish steel industry
2014
Many big companies around the world have solid Six Sigma infrastructures and it is easy to find in literature successful case studies. Conversely, small and medium-sized enterprises (SMEs) generally suffer lower attention in the literature. This happens because SMEs have only recently approached the methodology; they have weaker connection with the academia; or they do not rigorously pursue the frameworks. This paper is based on a Six Sigma project in a Swedish medium-sized company that produces steel tubes mainly for hydraulic applications. The project focused on the improvement of warehouse activities related to cutting processes. This Black Belt project was part of a Six Sigma education …
Studies on the genus Capparis L. (Capparaceae) in Lao PDR. VI: a new species from the Bolikhamxai Province
2022
A new species of Capparis, C. phatadke, is described and illustrated from the Bolikhamxai Province, central Lao PDR. The new species is characterized by lianous habit, brown-reddish indumentum, straight stipular thorns, laminar bracts, large flowers arranged in terminal corymbs or subumbels, long filaments and large ovary. It is so far known from a single locality, where has been observed in mixed deciduous forest and secondary forest in a limestone area. Its ecology and phenology are discussed, and its conservation status is assessed.
