Approfondimento: il controllo strategico nelle imprese vitivinicole
No full textIllustrare con chiarezza e semplicità il controllo di gestione: questa è la finalità del libro che descrive gli strumenti e i modelli di analisi necessari per programmare e monitorare le performance aziendali. Gli Autori espongono in maniera organica i principali meccanismi di controllo e, al contempo, nel testo, prestano particolare attenzione ai modelli che aiutano a interpretare, affrontare e risolvere i problemi di gestione caratteristici dell’attuale contesto competitivo (come, ad esempio, la value chain analysis, il life-cycle costing, lo strategic management accounting). Il richiamo a quanto avviene, in materia di controllo, nel contesto italiano contribuisce a stimolare nel lettore una riflessione sulla concreta applicabilità delle soluzioni proposte nel testo. Interessati a questo volume sono manager, professionisti, consulenti, studenti e tutti coloro che intendono rispondere a un bisogno, sempre più sentito, di acquisire competenze di controllo di gestion
Meteorological impact of realistic Terra Nova Bay polynyas
No full textThe energy exchange between the ocean and the atmosphere in the Antarctic marginal sea ice zone is influenced by the extent of sea-ice cover. In areas of open water, a direct contact is established and intense energy exchanges occur, due to the large difference of temperature between the water and the air above it. This implies that the polynyas are areas where the ocean exchanges energy with the atmosphere and as a result they have an effect on the polar meteorology/climate. The work presented here concerns real polynya events in the region of Terra Nova Bay (TNB), Antarctica, where a recurring coastal polynya occurs nearby the Italian Antarctic Base. The aim is the study of the impact of polynyas on the atmosphere by three-dimensional numerical simulations. The ETA model (Mesinger et al., 2006) is used and ECMWF and NCEP data provided the initial and boundary conditions. The model had already been successfully used in the Antarctic area (Casini and Morelli, 2007) A polynya of realistic size (as observed by satellite image) was included in the initial conditions for the simulations and a study of the air circulation during the events is found in Morelli et al. (2007), Morelli and Casini (2008), Morelli et al. (2009). The Eta Model reproduced the evolution of upper and mod-level conditions in good agreement with AVHRR observations (Morelli, 2008, Morelli and Parmiggiani, 2009). Also, the simulated 10 m wind was well correlated with the observed extension of the polynya.In order to isolate the effect of the presence of the open water area on the structure of the atmospheric boundary layer and on the atmospheric circulation, further simulations were performed without the presence of the polynya, i.e. with its extent covered with sea ice. The numerical simulations show that the polynyas act to increase the speed of the air above them and generate strong heat fluxes that warm the air. The effects are found over and downwind the sea ice free area.Results from the Eta Model runs show that a polynya modifies the atmosphere up to a height of several hundred meters and over a long distance from its location. A structure, as a thermal cyclone, develops over the eastern side of the polynyas. This structure is embedded in the pressure field simulated also without taking into account the polynya

An upgraded version of the Eta Model applied to Antarctic case studies
No full textUpgrades have been implemented over a number of years in an open source version of the Eta Model, posted at its CPTEC web site (http://etamodel.cptec.inpe.br/). They were summarized in Mesinger et al. (2011) and examined in detail in Mesinger et al.( 2012). In short: within dynamics, two major upgrades are the introduction of "sloping steps" and the use of the piecewise-linear vertical advection of dynamic variables. Several refinements on the calculation of exchange coefficients, conservation in the vertical diffusion, and diagnostic calculation of 10-m winds have been made. Vapor and hydrometeor loading in the hydrostatic equation were included. Within physics, efforts in refining the two Eta convection schemes received most attention. This recent version of the Eta Model has been applied to polynya events, accompanied by katabatic wind, at Terra Nova Bay (TNB), Antarctica. The TNB polynya is an area of coupling between the components of the sea ice-ocean-atmosphere system. Locally enhanced surface exchange processes are considered to have important consequences for the atmosphere (Morelli, 2011) and ocean processes, as well as for ice formation and the associated brine release. Adjustments of the Eta pre-processor have been made to allow for the distinctive polar conditions and for the use of ECMWF data as initial and boundary conditions. It is also being developed a thermodynamic model of sea ice interaction for a more realistic treatment of the sea ice-atmosphere. The numerical simulations have a horizontal resolution of about 8 Km. The results will be compared with observational data at the surface, with soundings and satellite images. The observations, used for the comparison, are available by Antarctic Meteorological Research Center, Space Science and Engineering Center, University of Wisconsin-Madison and the Programma Nazionale di Ricerche in Antartide (P.N.R.A.), Osservatorio Meteo-Climatologico.F Mesinger, Chou S C, Gomes J, Jovic D, Lazic L, Lyra A, Bustamante J, Bastos P, Morelli S, Ristic I (2011) An upgraded Version of the Eta Model.

Invenustus amator: una analisi di Catull. 69 e 71.
No full textUna analisi dei carmi 69 e 71 di Catullo, sotto il profilo testuale, linguistico e storico-letterario. Il personaggio dell’‘amante sgraziato’ viene caratterizzato in modo un po’ differente nei due carmi, ricorrendo in entrambi i casi al motivo scommatico dei fetori corporei, di cui si ricostruiscono i presupposti nella poesia greco-latina, da Ipponatte (fr. 116, 8 W. = 196, 8 Degani) alla commedia greca (Aristoph. Pax 810-813; Ach. 848-853), all’epigramma greco (Lucill. AP 11, 239-240), fino ai poeti latini (Plaut. Most. 38-41; Pseud. 737-738; Lucil. 1067 M. etc.). Gli effetti caratterizzanti del tema della gotta, nel c. 71, rimandano a un quadro di dissolutezza e di deboscia, di cui la podagra è effetto diretto (cfr. nell’epigramma greco già Edilo, AP 11, 414, e poi Nicarch. AP 5, 39 e Strato AP 12, 243), sicché sembra farsi più caustica e mordace, probabilmente rispetto allo stesso bersaglio (il Rufus del c. 69) la satira dei vizi morali
Combined observations of a Bora event in the Adriatic Sea by means of ETA model and SAR data
No full textThe Bora is a cold, strong, low level wind which blows from the northeast along the Adriatic coast (Ivančan-Picek and Tutiš, 1996, Lazić and Tošić, 1998, Morelli and Berni, 2002). Bora wind is known to have multiple surface wind jets linked to the orography of the Dinaric Alps and alters significantly the sea status (Cesini et al, 2004).
A recent version of the Eta model (Mesinger et al, 2012), which is a three-dimensional, primitive equation, grid-point model, was used to represent the low level wind field corresponding to the Bora event occurred at the beginning of February 2012. Numerical simulations, initialized by ECMWF data, were performed with different horizontal resolutions (approximately 20 km and 4 km) and domain extent. The numerical simulations describe the atmospheric conditions of the period and reveal the spatial structure of the wind, in good agreement with the understanding as well as the observational knowledge of the bora.
In addition, the wind speed and direction was estimated on the ASAR images. Wind directions were obtained by exploiting a novel technique based on the use of 2D continuous wavelets (Zecchetto and De Biasio, 2001, 2008). Then, the retrieved wind directions were used to estimate the wind speed from the ASAR NRCS by inverting the semi-empirical backscatter model CMOD-5 (Hersbach, 2005).
The ASAR observed morphology, wake patterns and, where present, dual-jet structure of the Bora wind were analysed for 2 and 5 February at the two different Eta resolution scales. Results of the comparisons between Eta prediction and ASAR data will be shown.
