Enrico IV ovvero il potere salvifico dell’immaginazione
No full textAmong the writings published by Umberto Artioli a year before his sudden death in July 2004, there is a study on Luigi Pirandello’s Enrico IV. Abandoning the usual realistic interpretation of the text, the scholar highlights the allegorical path underneath its conception and a number of references related to the evangelical Last Supper. The core of Pirandello’s hero teachings identifies in the theatrical imagination the way to salvation. Although the initiation of his disciples fails, the Author outlines the characteristics of a new type of artist and his ideal relationship with the public; a figure that will inspire Bontempelli’s ideas on an extremely versatile and eclectic interpreter to be driven on stage like a puppet
The Fractal Structure of the Universal Steenrod Algebra: An Invariant-theoretic Description
No full textAs recently observed by the second author, the mod2 universal
Steenrod algebra Q has a fractal structure given by a system of nested
subalgebras Qs, for s > N, each isomorphic to Q. In the present paper
we provide an alternative presentation of the subalgebras Qs through
suitable derivations s, and give an invariant-theoretic description of
them
Trading arrangements and industrial development
No full textHow do different trading arrangements influence the industrialization process of developing countries? Can preferential trading arrangements (PTAs) be superior to multilateral liberalization, or at least an alternative when multilateral liberalization proceeds slowly? If so, what form should the PTAs take? Are developing countries better advised to seek PTAs with industrial countries or among themselves? Traditional analysis of these issues has been based on the idea of trade creation and trade diversion. The problem with this analysis is that it starts from assuming a pattern of comparative advantage of newly industrialized countries. The experience of these countries suggests the need for an analysis in which the pattern of comparative advantage is not set in stone but is potentially flexible, and in which less developed countries can develop and converge in both income and economic structure to industrial economies. The authors outline an alternative approach for analyzing the role of trade in promoting industrial development. There are few fundamental differences between countries that generate immutable patterns of comparative advantage. Instead the pattern of trade and development in the world economy is determined mainly by history. Cumulative causation has created concentrations of industrial activity in particular locations (industrial countries) and left other areas more dependent on primary activities. Economic development can be thought of as the spread of these concentrations from country to country. Different trading arrangements may have a major impact on this development process. By changing the attractiveness of countries as a base for manufacturing production they can potentially trigger or postpone industrial development. This approach explains why firms are reluctant to move to economies that have lower wages and labor costs, and shows how trade liberalization can change the incentives to become established in developing countries. It provides a mechanism through which import liberalization can have a powerful effect in promoting industrialization. And it suggests that import liberalization may create or amplify differences between liberalizing countries with the possible political tensions this may create. While these features are consistent with the world economy, they fall short of providing convincing empirical support for the approach. Using the approach, the authors derive number of conclusions about the effects of trade liberalization. First, that unilaterally liberalizing imports of manufactures can promote development of the local manufacturing industry. The mechanism is forward linkages from imported intermediates, but this may be interpreted as part of a wider package of linkages coming from these imports. Second, the gains from liberalization through PTA membership are likely to exceed those obtained from unilateral action. South-South PTAs will be sensitive to the market size of member states, and North-South PTAs seem to offer better prospects for participating Southern economies, if not for North and excluded countries. Third, the effects of particular schemes (such as the division of benefits between Southern economies) will depend on the characteristics of the countries and cross-country differences in these characteristics.Economic Theory&Research,Environmental Economics&Policies,Water and Industry,Labor Policies,Banks&Banking Reform,Economic Theory&Research,Environmental Economics&Policies,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,Trade and Regional Integration,Water and Industry
Translating wordplay in The Bridge by Harold Hart Crane
No full textAbstract
This essay focuses on a new translation of the divisive poem The Bridge by
Harold Hart Crane. Published in the United States in 1930 and written
during a period of unprecedented literary creativity dominated by T.S. Eliot
and Ezra Pound, the poem encountered many obstacles in its
acknowledgment. Although Crane is now considered one of the major
modernist poets and The Bridge his masterpiece, the poem was originally
judged a failure. The reason for its negative reception depended on many
factors: the work did not conform to the canon of the age; the enthusiasm of
the author that created excessive expectations; its huge number of puns were
difficult to interpret and translate. In Italy the poem was translated at an
academic level for the first and last time in 1967 by Roberto Sanesi, although
a partial version appeared in a monograph by Pietro Spinucci published in
1966. Both have long been out of print. Considering that the translation
process of a text is related to context and time, a new rendering of The Bridge
into Italian has been proposed examining its puns.

Immunohistochemical investigation on canine meningiomas
No full textImmunohistochemical staining patterns were studied in brain and spinal cord meningiomas of the dog. Nineteen archived cases were selected and classified according WHO classification (Koestner et al. 1999). They included five transitional, five meningothelial, two fibroblastic, two angiomatous and five anaplastic meningiomas. To differentiate meningioma from other central nervous system tumors a panel of immunohistochemical markers (vimentin, S100, Glial Fibrillary Acidic Protein (GFAP), Pancytokeratin, AE1/AE3 cytokeratin) were checked. Moreover, E-cadherin and beta-catenin expressions were investigated in order to identify the role they eventually play in meningioma’s morphogenesis. In all cases, vimentin labelling was strong and was detected in 100% of neoplastic cells. S100 expression was detected in 2 out of 19 cases (meningothelial and anaplastic type), showing to be mild and focal. GFAP, Pancytokeratin and AE1/AE3 cytokeratin were negative in all cases under study. E-cadherin was expressed in 3 out of 19 cases as focal, granular, cytoplasmic/membranous positivity. Whorl figures were E-cadherin positive in one transitional meningioma, one meningothelial and one anaplastic hystotypes, while neoplastic cells were negative in both the fibroblastic and angiomatous morphotype. Beta-catenin was not expressed. E-cadherin expression reflected the presence of homotypic interactions of neoplastic cells in the meningothelial as well as transitional hystotypes
Low-energy cooling of a medicine warehouse in a hot humid climate
No full textThe research was aimed at the definition of a design hypothesis for the construction of a pharmaceutical warehouse in a hot humid area of southern Sudan. The candidate hypotheses were based on an existing prefabricated single-storey pitched-roof steel structural systems 18 m long and 9 m wide and had to be constructible at a low cost and using local materials. At climatic level, the goal was that daily d.b. temperatures not exceeding 27-28 °C were reached by passive of very low-energy means, which was not easy to achieve in the given conditions. A construction hypothesis was made by the author adopting the following solutions: a) masonry for the walls, insulated from the outside and protected by rainscreens; b) a heavy concrete floor insulated from the outside and suspended upon a ventilated cavity; c) a ventilated and insulated metal-sheet pitched roof. Three passive cooling strategies based of the described solution have been tested by the author through the use of the ESP-r software tool: the first exploiting nightly stack effect ventilation, the second based on forced night-only fan ventilation, and the third based on night top-down ventilation activated by roof radiant cooling. The second and third hypotheses have been found to meet the thermal requirement and the second one was at last selected, because it seemed to guarantee lower construction costs and be less dependent from weather conditions
Espressione immunoistochimica di caderina-E e beta-catenina nel meningioma del cane
No full textI meningiomi derivano dalla proliferazione neoplastica dei villi aracnoidei della leptomeninge aracnoide e sono i tumori primitivi più frequenti del sistema nervoso centrale del cane. L’esistenza di numerosi istotipi è dovuta alla loro origine mista, sia mesodermica che neuroectodermica. A causa di questa molteplicità di istotipi la diagnosi risulta talvolta difficile, rendendo necessario l’utilizzo di marcatori immunoistochimici. Scopo del presente lavoro è di testare l’espressione della Caderina E e della beta-catenina, molecole di adesione epiteliale, per considerare il loro eventuale ruolo nella morfogenesi di questi tumori, in associazione ad un pannello di anticorpi già in uso nella diagnosi di meningioma.
Un pannello immunoistochimico comprendente vimentina, proteina S-100, Proteina Gliale Fibrillare Acida, pancitocheratine, Caderina E e beta-catenina è stato applicato a 18 meningiomi canini.
Tutti i meningiomi mostrano una forte e diffusa positività per la vimentina, 2 su 18 sono debolmente e focalmente positivi all’S-100, 3 su 18 mostrano una positività eterogenea alla Caderina E. La Proteina Gliale Fibrillare Acida, le pancitocheratine e la beta-catenina non sono espressi dalle cellule neoplastiche.
La forte e diffusa positività alla vimentina conferma la diagnosi di meningioma, l’immunoreattività per S-100 è stata scarsa e lieve e non è da considerarsi utile nell’iter diagnostico. L’espressione della Caderina E in 3 differenti istotipi, in particolare in corrispondenza delle tipiche formazioni a vortice, suggerisce un possibile ruolo di questa molecola nell’architettura strutturale di questi tumori. Saranno necessarie ulteriori indagini per verificare il reale significato di una tale espressione nel meningioma di cane
Design optimization of a suspended glazed corridor in Milan
No full textThe study in question, commissioned by the public Administration of the Province of Milan, has taken place in the context of the refurbishment of the Feltrinelli Technical Industrial Institute in Milan, following a first design hypothesis by the Province’s technical offices. The original retrofit proposal aimed to connect three buildings of the complex by the means of a glazed, walkable, suspended corridor, similar to those typical of airports. The author evaluated the thermal behaviour of the suspended corridor both as defined in the original design hypothesis and as modified according to alternative design hypotheses based on variation of solar shadings and envelope operability and composition. The suspended corridor had to be connected with a sunspace that the author suggested to be built on the south facade of a building nearby, and therefore had to be compatible with it at aesthetic and construction level. The thermal effects of the considered design hypotheses have been evaluated using the ESP-r software tool, and the conclusions deriving from the simulations results have been crossed with architectural and construction considerations
Challenging the author: Gavin Douglas's Eneados
No full textGavin Douglas’s Eneados, a translation into the “Scottis” tongue of Virgil’s Aeneid, completed in 1513 and first published in London in 1553, presents, as well as the translation of the additional thirteenth book by Maphaeus Vegius, original prologues and marginal notes to the text, rubrics and articulate conclusive material. The present paper analyses this complex paratext as evidence of Douglas’s almost philological attention to the original and his preoccupation with a faithful reproduction; it is also suggested that the models for his organization of the commentary might be both medieval (i.e., manuscripts such as Petrarch’s Virgilius Ambrosianus) and early modern, as in the case of editions of classical works: the most apt example being Jodocus Badius Ascensius’ edition of the Aeneid, printed in 1501. The Eneados thus stands on the threshold between manuscript and print, and might have indicated new possibilities of use of the printing medium in Scotland, and of the value of the translation of a classical text, had history not intervened with the Scottish defeat at Flodden Fields in 1513, which put a temporary stop both to the circulation of the Eneados and to the development of Scottish printing
