La pianificazione strategica
No full textIl contributo al libro di Robert N. Anthony, Vijay Govindarajan e Diego Maria Macrì (a cura di) "Management Control Systems: tecniche e processi per implementare le strategie" esamina, in una prospettiva organizzativa, il processo di pianificazione strategica. Il capitolo specificamente illustra la natura della pianificazione strategica, le tecniche utilizzate per analizzare, valutare e scegliere diverse alternative, i metodi utili per monitorare i programmi in corso di esecuzione e le diverse fasi nelle quali si articola il processo di pianificazione. Le idee e i temi presentati si riferiscono implicitamente a un’impresa di medio-grandi dimensioni, con una sede centrale e una struttura decentrata costituita da una molteplicità di unità di business. In un’organizzazione di questo tipo il processo di pianificazione strategica è complesso e articolato in quanto si svolge sia presso la sede centrale sia presso le singole unità

Hydrogen peroxide formation and iron ion oxidoreduction linked to NADH oxidation in radish plasmalemma vesicles
No full textPreviously, we showed the presence in radish (Raphanus sativus L.) plasmalemma vesicles of an NAD(P)H oxidase, active at pH 4.5–5.0, which elicits the formation of anion superoxide (Vianello and Macri (1989) Biochim. Biophys. Acta 980, 202–208). In this work, we studied the role of hydrogen peroxide and iron ions upon this oxidase activity NADH oxidation was stimulated by ferrous ions and, to a lesser extent, by ferric ions. Salicylate and benzoate, two known hydroxyl radical scavengers, inhibited both basal and iron-stimulated NADH oxidase activity. The iron chelators EDTA (ethylenediaminetetraacetic acid) and DFA (deferoxamine melysate) at high concentrations (2 mM) inhibited the NADH oxidation, whereas they were ineffective at lower concentrations (80 μM); the subsequent addition of ferrous ions caused a rapid and limited increase of oxygen consumption which later ceased. Hydrogen peroxide was not detected during NADH oxidation but, in the presence of salicylate, its formation was found in significant amounts. NADH oxidase activity was also associated to a Fe2+ oxidation which was only partialy inhibited by salicylate. Ferrous ion oxidation was partially inhibited by catalase and prevented by superoxide dismutase, while ferric ion reduction was abolished by catalase and unaffected by superoxide dismutase. These results show that during NADH oxidation iron ions undergo oxidoreduction and that hydrogen peroxide dismutase. These results show that during NADH oxidation iron this oxidation appears linked to the univalent oxidoreduction of iron ions by a reduced flavoprotein of radish plasmalemma which is then converted to a radical form. The latter, reacting with oxygen generates the superoxide anion which dismutates to H2O2. Hydrogen peroxide, through a Fenton's reaction, may react with Fe2+ to produce hydroxyl radicals, or with Fe3+ to generate the superoxide anion
Existence and regularity for solutions of quasilinear degenerate elliptic systems
No full textThe existence of a solution to a quasilinear system of degenerate equations is proved, assuming that the datum has an intermediate degree of summability and that the off -diagonal coefficients have a support contained in a crossed staircase set. The support required in this paper is larger than the one assumed in a previous work

A new gemstone from Italy: "Violan quartz."
No full textWe report the results of three mark-release-recapture experiments carried out in an urban area in Rome, Italy, to study the active dispersal of Aedes albopictus (Diptera: Culicidae). The 4.3% recapture rate obtained supports the use of sticky traps in MRR experiments to study the dispersal of Ae. albopictus females. Most fluorescent dust-marked females were recaptured at the gravid stage at 50-200 m from the release sites during the first 9 days after release. The average of daily-MDTs (Mean Distance Traveled) was 119 m and the maximum observed distance travelled ranged from 199 m to 290 m in the three replicates. These data provide the first information about the dispersal of Ae. albopictus in a temperate European area and appear to be consistent with the few data available on this subject from other urban areas, where dispersal was constrained by physical barriers. Although caution should be taken in generalizing these results, they should be considered when planning control activities in urban areas in Italy, as well as in other European countries. This is particularly relevant if control is intended to interrupt pathogen transmission in cases of possible arbovirus epidemics, such as the Chikungunya outbreak that occurred in Ravenna, Italy in 2007.

Il controllo manageriale dei progetti
No full textIl contributo al libro di Robert N. Anthony, Vijay Govindarajan e Diego Maria Macrì (a cura di) "Management Control Systems: tecniche e processi per implementare le strategie" esamina, in una prospettiva organizzativa, il processo di pianificazione strategica. Più specificamente tratta il processo di controllo manageriale in un’organizzazione che non svolga attività in modo continuo e ripetitivo. Dopo aver analizzato la natura di un progetto e gli aspetti per i quali le relative modalità di controllo differiscono da quelle tipiche delle attività continuative, la pubblicazione si focalizza sull’ambiente nel quale il controllo di progetto ha luogo e le fasi nelle quali esso si esplicita: la pianificazione, l’esecuzione e la valutazione. Particolare enfasi è posta sul project management come tema interdisciplinare che mutua schemi concettuali dagli studi organizzativi, dalla ricerca operativa, dal controllo di gestione e dalla qualità
Diritto e religione. La dimensione europea del fenomeno religioso
No full textIl saggio analizza il riflesso dell'ordinamento euro-unitario sul diritto pubblico interno e sulla dimensione giuridica della libertà religiosa. L'obiettivo del lavoro è quello di provare a dimostrare come, in una dimensione comune europea, sia più consona una disciplina interna del fattore religiosa tramite legge ordinaria
