L’outsourcing controllato come strumento di miglioramento della gestione aziendale. Il processo di ristrutturazione organizzativa del gruppo Ferrovie dello Stato. Il caso Grandi Stazioni.
No full textSi analizza in questo lavoro il concetto di outsourcing effettuato in particolari circostanze. Nell’ipotesi adottata dal Gruppo FS, con la creazione di Grandi Stazioni S.p.A. si è venuto infatti a creare un nuovo concetto che può essere definito come “outsourcing controllato”. Con questa differente definizione si vuole intendere ancora l’affidamento ad un soggetto terzo di specifiche attività, con la differenza che, in questo caso, il terzo è rappresentato da una società appositamente costituita dalla capogruppo con capitali del gruppo stesso. Tale strada sembra essere quella ultimamente prescelta sia per società private che, ed a maggior ragione, per società pubbliche
Il settore petrolifero e la legislazine ambientale:il sistema di raffinazione in Italia - XXI Congresso nazionale di merceologia - Foggia, settembre 2004
No full textEnvironmental laws which affect the oil sector are among the most conspicuous of all the main industrial sectors because of their number and because of the size of the interventions which are required. These norms partly concern the quality of products and also the protection of the territory in relation to the activities plants, particularly refineries (they also regard logistics, transportation and distribution). In the specific case of refineries norms regulate emissions, safety and health of workers and the protection of the surrounding environment.A great many of the norms have already been in effect for years at the community level and applied, with some adaptations, (sometimes becoming more severe) to the Italian context.The resources the oil industry commits to environmental aims has grown over time and currently accounts for the largest portion of annual investments

Palladium (0) olefin complexes bearing purine-based N-heterocyclic carbenes and 1,3,5-triaza-7-phosphaadamantane (PTA): Synthesis, characterization and antiproliferative activity toward human ovarian cancer cell lines
No full textA complete series of new η2-olefin palladium (0) complexes bearing purine-based N-heterocyclic carbenes or PTA (1,3,5-triaza-7-phospaadamantane) as spectator ligands have been synthetized and exhaustively characterized. The first single-crystal X-ray structure of a PTA complex of palladium (0) have been also reported. The most part of these compounds have been tested as antiproliferative agents toward two different human ovarian cancer cell lines A2780 and A2780cis, respectively cisplatin sensitive and resistant. The resulting IC50 values have shown the significant antiproliferative activity of our complexes, often comparable with cisplatin. In some cases, this cytotoxicity is associate with induction of apoptosis. The efficiency of the Pd (0) complexes is heavily influenced by the combination of spectator ligands and coordinating olefin. Finally, two of the most active compounds against cancer cells proved scarcely active on non-tumor fibroblast cells MRC-5

No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
