"Pigliar d’assalto la lingua italiana" : Il metodo Capurro per le scuole reggimentali
No full textTra le proposte glottodidattiche prosperate per tamponare l’analfabetismo nel periodo post-unitario, tuttora è poco noto il metodo Capurro. Eponimo dell’abate inventore (Merella, Novi Ligure 1810 – ivi 1882), il metodo è l’unico raccomandato nei regolamenti per le scuole reggimentali, predisposte dal ministero della guerra al recupero delle reclute analfabete, nei decenni successivi all’unificazione. Sperimentato nelle scuole di diverse province dell’Italia centro-settentrionale e oltralpe, il metodo vantava risultati eccellenti per recuperare all’alfabetismo i giovani adulti coscritti, in un contesto già pioneristico nella diffusione dell’italiano comune quale era l’esercito unitario.
Il presente contributo traccia le tappe spazio-temporali della storia di questo metodo, individuandone la nascita e l’espansione sino al suo approdo nelle scuole reggimentali. Quindi, dopo aver precisato i destinatari, gli obbiettivi e gli esiti documentati, si illustrerà nel dettaglio il metodo, descritto nella Guida teorico-pratica del sistema Capurro (1875) destinata ai maestri e declinata nel corrispettivo sillabario (1878) e nel libro di lettura (1873) per gli allievi. Inoltre, un periodico specializzato ne potenziava la divulgazione.
Malgrado la comprovata fortuna, tra i contemporanei non mancarono perplessità tanto sulla meccanica del metodo quanto sulla sua efficacia, dibattute infino ai banchi del parlamento nel 1879.Among methods of Italian language teaching, which flourished after Italian unification to contain illiteracy, still it is little known Capurro’s method. This method, which takes its name from its inventor (born in Merella, Novi Ligure 1810 – dead in Novi Ligure 1882), was the unique method recommended in Regulations for regimental schools, i.e. schools organized by Ministry of War to recover illiterate recruits, in the decades after Italian unification.
Capurro’s method was experimented in schools of different provinces in Northern and Central Italy, where it boasted excellent results with illiterate young adult, in a context (the Army) which was pioneering for the spread of Italian language.
Aim of this contribution is to track the history of this method, identifying its birth and its expansion until its adoption in the regimental schools. After identifying receivers, goals and proved outcomes, this essay will explain the method in detail, analyzing Guide of Capurro’s method for teachers (1875), syllabary (1878), primer for students and three specialized periodicals, which were developed to disclosure the method among teachers. Despite the proved success, contemporaries raised doubts about both process of the method and its effectiveness, which were debated into the Parliament in 1879
Basal melt, seasonal water mass transformation, ocean current variability, and deep convection processes along the Amery Ice Shelf calving front, East Antarctica
No full textDespite the Amery Ice Shelf (AIS) being the third largest ice shelf in Antarctica, the seasonal variability of the physical processes involved in the AIS-ocean interaction remains undocumented and a robust observational, oceanographic-based basal melt rate estimate has been lacking. Here we use year-long time series of water column temperature, salinity, and horizontal velocities measured along the ice shelf front from 2001 to 2002. Our results show strong zonal variations in the distribution of water masses along the ice shelf front: modified Circumpolar Deep Water (mCDW) arrives in the east, while in the west, Ice Shelf Water (ISW) and Dense Shelf Water (DSW) formed in the Mackenzie polynya dominate the water column. Baroclinic eddies, formed during winter deep convection (down to 1100 m), drive the inflow of DSW into the ice shelf cavity. Our net basal melt rate estimate is 57.4 ± 25.3 Gt yr−1 (1 ± 0.4 m yr−1), larger than previous modeling-based and glaciological-based estimates, and results from the inflow of DSW (0.52 ± 0.38 Sv; 1 Sv = 106 m3 s−1) and mCDW (0.22 ± 0.06 Sv) into the cavity. Our results highlight the role of the Mackenzie polynya in the seasonal exchange of water masses across the ice shelf front, and the role of the ISW in controlling the formation rate and thermohaline properties of DSW. These two processes directly impact on the ice shelf mass balance, and on the contribution of DSW/ISW to the formation of Antarctic Bottom Water
Platelet ice attachment to instrument strings beneath the Amery Ice Shelf, East Antarctica
No full textOceanographic instruments suspended beneath the Amery Ice Shelf, East Antarctica, have recorded sporadic pressure decreases of 10–20 dbar over a few days at three sites where basal marine ice growth is expected. We attribute these events to flotation due to platelet ice accretion on the instrument moorings. Some events were transient, rapidly returning to pre-event pressures, probably through dislodgement of loosely attached crystals. Driven by these pressure changes, temperatures recorded by the shallowest instruments (within 20 m of the shelf base) tracked in situ freezing temperatures during the events. These observations provide indirect evidence for the presence of frazil ice in the sub-ice-shelf mixed layer and for active marine ice accretion. At one site we infer that a dense layer of platelet ice ?1.5 m thick was accreted to the ice shelf over a 50 day period. Following some permanent abrupt pressure decreases (which we interpret as due to the lodgement of the uppermost instrument at the ice-shelf base), altered background trends in pressure suggest compaction rates of 3–4 m a–1 for the accreted basal platelet layer. Attachment of platelet ice and resulting displacement of moorings has ramifications for project design and instrument deployment, and implications for interpretation of oceanographic data from sub-ice-shelf environments
Ocean-ice shelf interaction in East Antarctica
No full textAssessments of the Antarctic contribution to future sea level rise have generally focused on ice loss in West Antarctica. This focus was motivated by glaciological and oceanographic observations that showed ocean warming was driving loss of ice mass from the West Antarctic Ice Sheet (WAIS). Paleoclimate studies confirmed that ice discharge from West Antarctica contributed several meters to sea level during past warm periods. On the other hand, the much larger East Antarctic Ice Sheet (EAIS) was generally considered to be relatively stable because of being largely grounded above sea level and therefore protected from ocean heat flux. However, recent studies suggest that a large part of the EAIS is grounded well below sea level and that the EAIS also retreated and contributed several meters to sea level rise during past warm periods. We use ocean observations from three ice shelf systems to illustrate the variety of ocean-ice shelf interactions taking place in East Antarctica and to discuss the potential vulnerability of East Antarctic ice shelves to ocean heat flux. The Amery and the Mertz are “cold cavity” ice shelves that exhibit relatively low area-averaged basal melt rates, although substantial melting and refreezing occurs beneath the large and deep Amery Ice Shelf. In contrast, new oceanographic measurements near the Totten Ice Shelf show that warm water enters the sub-ice-shelf cavity and drives rapid basal melting, as is seen in West Antarctica. Totten Glacier is of particular interest because it holds a marine-based ice volume equivalent to at least 3.5 m of global sea level rise, an amount comparable to the entire marine-based WAIS, and recent glaciological measurements show the grounded portion of Totten Glacier is thinning and the grounding line is retreating. Multiple lines of evidence support the hypothesis that parts of the EAIS are more dynamic than once thought. Given that the EAIS contains a volume of marine-based ice equivalent to 19 m of global sea level rise, the potential for ocean-driven melt to destabilize the marine-based ice sheet needs to be accounted for in assessments of future sea level rise

No full textEn la mesa redonda Norma y variación en la lengua del siglo XVIII, presidida y moderada por Daniel M. Sáez Rivera, participaron diversos ponentes que abordaban tres diferentes tipos de texto en el siglo XVIII con diferentes perspectivas. De este modo, en La organización informativa en los textos periodísticos del s. XVIII: el Diario Pinciano, según la propuesta de Margarita Borreguero y Álvaro Octavio de Toledo, expuesta por el último, ya que la primera no pudo asistir a las Jornadas, se estudiaba el discurso narrativo en el periodismo
