This paper analyses the extent to which intensive investments in public capital may have had an unfavourable impact on the regional trade balances across the 20 Italian regions. Our working hypothesis is that investments in public capital, while stimulating the demand for tradables across the regions, may have a limited positive impact on the supply of tradables in regions characterised by relatively low productivity like the South of Italy (or Mezzogiorno). The empirical results are consistent with our expectations and suggest that programs of investments in public capital should be accompanied by additional policy measures that can remove the structural factors that hamper the total factor productivity growth in specific areas. © Springer-Verlag 2008.

Methicillin-resistant Staphylococcus aureus (MRSA) Sequence Type (ST)1, Clonal Complex(CC)1, SCCmec V is one of the major Livestock-Associated (LA-) lineages in pig farming industry in Italy and is associated with pigs in other European countries. Recently, it has been increasingly detected in Italian dairy cattle herds. The aim of this study was to analyse the differences between ST1 MRSA and methicillin-susceptible S. aureus (MSSA) from cattle and pig herds in Italy and Europe and human isolates. Sixty-tree animal isolates from different holdings and 20 human isolates were characterized by pulsed-field gel electrophoresis (PFGE), spa-typing, SCCmec typing, and by micro-array analysis for several virulence, antimicrobial resistance, and strain/host-specific marker genes. Three major PFGE clusters were detected. The bovine isolates shared a high (≥90% to 100%) similarity with human isolates and carried the same SCCmec type IVa. They often showed genetic features typical of human adaptation or present in human-associated CC1: Immune evasion cluster (IEC) genes sak and scn, or sea; sat and aphA3-mediated aminoglycoside resistance. Contrary, typical markers of porcine origin in Italy and Spain, like erm(A) mediated macrolide-lincosamide-streptograminB, and of vga(A)-mediated pleuromutilin resistance were always absent in human and bovine isolates. Most of ST(CC)1 MRSA from dairy cattle were multidrug-resistant and contained virulence and immunomodulatory genes associated with full capability of colonizing humans. As such, these strains may represent a greater human hazard than the porcine strains. The zoonotic capacity of CC1 LA-MRSA from livestock must be taken seriously and measures should be implemented at farm-level to prevent spill-over.

Alfonso V of Aragon (1396-1458), who won from his contemporaries the title “the Magnanimous”, became one of the most brilliant fifteenth century monarchs, not only because of being a shrewd politician and king of one of the main kingdoms in the Iberian Peninsula, but also due to his cultural activity. Thanks to him the Aragonese territories were extended throughout the Mediterranean up to Naples, where he established a magnificent court that turned into maybe the most remarkable centre of intellectual vitality and development of Humanism. His patronage attracted a considerable number of leading poets of the period, as well as the most important Italian humanists. The presence of so many writers and outstanding scholars, together with the academic environment that the monarch encouraged, promoted an enormous literary production in four languages: Latin, Spanish, Catalan and Italian. Additionally, the valuable library gathered by the king and the Academy founded in order to spread knowledge illustrate part of his intellectual concerns. This way, through his love to literature and generosity to men of letters, Alfonso the Magnanimous boosted the culture of that time. The principal protagonist in the cultural activities of the circle of erudites formed around the sovereign was Antonio Beccadelli, called Panormita (1394-1471). He, one of the most prominent personalities of Italian Humanism, assumed the role of main royal advisor. His work De dictis et factis Alphonsi regis (The sayings and deeds of king Alfonso), which will be studied in our dissertation, became a very popular text about Alfonso’s personality, as a kind of biography based on anecdotes of the Magnanimous’ life by way of exempla to be imitated. The success of these episodes lasted for a long time and they are appreciated even nowadays. The work was valued as specula principum and had great impact in sixteenth century, when De dictis was republished several times and translated from Latin into Spanish. One of these translations, the one by Fortún García de Ercilla, caught our interest since it is in a manuscript signed by Ercilla himself and this version is still unpublished...

As it is well known, the Renaissance in Spain cannot be understood without a deep knowledge of the Italian quattrocento: art and thinking have an important debt with a culture that shaped a new society that can be named Modern Era. So, there are many intellectuals that are the main reference to our writers: Leonardo Bruni, Giannozzo Manetti, Bartolomeo Facio, Antonio Beccadelli, Poggio Bracciolini, Francesco Filelfo, Flavio Biondo, Lorenzo Valla, Vespasiano da Bisticci, Pier Candido Decembrio, Guarino da Verona, Pico della Mirandola, Marsilio Ficino, and a big number that includes necessarily the name of Enea Silvio Piccolomini (1405-1464). In effect, the creator that became Pope as Pío II is one outstanding figure of that Humanism that early putted down roots in Spain, a country in construction that produced very important fruits in those years. Under these circumstances, this study has as main objective to analyse the large work of the humanist Pope par excellence, and to establish the relationship between his writings and genres, works and authors in the Iberian peninsula that wrote under his influence. Furthermore, in the following pages can be found a edition of the translation, by Diego López de Cortegana, of one of Picolomini’s works, the Tratado de la miseria de los cortesanos, a work that can be taken as an example of the attention payed to his works by authors like Juan de Lucena, Rodrigo Sánchez de Arévalo, Cristóbal de Castillejo or fray Antonio de Guevara. After a brief introduction that points that the attention to Enea Silvio Piccolomini is not diminishing, that, on the contrary, is clearly alive if we consider modern editions and translations to different languages, I concentrate on the biography of Pío II. With this purpose I take as base the text that this humanist wrote with the aim of building an adequate imago vitae that related the achievements in the religious sphere (with a failed promotion of a last crusade against the Turk) and also his creative labour. I refer to the Commentarii rerum memorabilium quae temporibus suis contingerunt, an extensive autobiography that did not spare the self-praise and conceals some controversial author’s facts, such as the “reconciling” thesis that undermined the Popes authority and power. In addition, in that chapter can be found a study of the writing process of the titles that includes Piccolomini’s bibliography, since we can think that the author’s commentary is extremely relevant to inform about the moment of writing and its purpose...

Inspired by a community psychology ecological perspective, this chapter addresses migration-related detention as part of that set of practices implemented by the EU and the Schengen Area to ensure internal security by strengthening external borders control. In particular, it focuses on the Italian context. Starting from a historical overview of the Italian legal and policy framework on migration, a critical analysis of the rationale for migrant detention and deportation is developed, highlighting the business interests at stake. In this regard, the concept of immigration industrial complex is utilized, emphasizing its similarities with the military and prison industrial complexes. Finally, the case of an Italian migration-related detention center is illustrated. We argue for the use of ecological multilevel analysis to grasp the complexity of these sites of confinement, and shed light on the forces and interests that revolve around them. Alternatives are advocated based on freedom and justice for all.

The intense use of glyphosate for weed control led to the emergence of several cases of resistance to this herbicide. Weeds can survive the application of herbicides due to several factors, which may or may not be related to the herbicide site of action. The objectives of this study were to quantify the accumulation of shikimate in ryegrass biotypes in response to glyphosate application; investigate possible mutations on the EPSPs gene in susceptible and resistant biotypes; and evaluate the response of ryegrass biotypes to the application of glyphosate after treatment with a metabolism inhibitor of cyt P450 monooxygenase.
