Political and institutional constraints on structural reforms: interpreting the Italian experience

During 2011 Italy reached the verge of a financial default because of its huge public debt. Neither the centre-right nor the centre-left governments that alternated in power in the 2000s were able to introduce the reforms necessary for reducing the debt and promoting growth. The impotence of the government became incompatible with the requirements of the country's continued presence in the eurozone. In November 2011, under the pressure of financial markets and eurozone institutions and leaders, the incumbent centre-right government was obliged to resign, and was substituted by a government composed of technocrats and experts, the Monti government. This lasted until December 2012 and was supported in parliament by a cross-partisan coalition; it was able to introduce some of the structural reforms required, because of the threat of default but also because it did not need to seek the electoral support of powerful constituencies. This article advances an interpretation of the Italian crisis of November 2011, identifying the political and institutional structures and the specific political conditions that fostered a policy stalemate in the country in the 2000s and whose persistence makes the continuation of reforms after the February 2013 elections uncertain.     

Pottery firing temperatures: a new method for determining the firing temperature of ceramics and burnt clay

A new method for determining the maximum firing temperature of ceramics and burnt clay is presented. The technique relies on measuring the magnetic susceptibility on a step-wise re-fired sample. The validity of the method has been tested by determining firing temperatures of two sets of clay samples fired at temperatures ranging from 400 to 1000 °C. Aliquots of the same samples have been studied petrographically by optical microscopy on thin sections and analyzed by powder X-ray diffraction in order to monitor structural and mineralogical changes as a function of temperature. The method is demonstrated on samples from four geographically widely different sites and it is applied to a larger set of ceramics of Late (ca. AD 900–AD 1450) and Inca (ca. AD 1480–AD 1532) periods from the Northwestern Argentine region, dating to a limited period of time prior to the fall of the Inca Empire. The method is shown to be a powerful tool in revealing archaeological information about the change in firing technologies in the pre-Hispanic societies in the Andean area through time.     

A dendrochronological analysis of Pinus pinea L. on the Italian mid-Tyrrhenian coast

In order to assess the response of the radial growth of Pinus pinea L. to climatic variability in Central Italy, dendrochronological and dendroclimatological analyses were carried out on five different populations scattered along the Tyrrhenian coasts of the peninsula. The aim of this study is to contribute to the understanding of the ecological demands of this species, particularly in the study area. For each site total ring, early-, and late-wood width chronologies were developed. Multidimensional analyses were performed for the three tree-ring datasets in order to analyze the relations between sites chronologies. Both Principal Component Analyses and hierarchical classifications highlighted an important difference of one site in respect to the other, probably due to site characteristics. Correlation functions were performed to infer the main climatic factors controlling the radial growth of the species. For a comparative study, we limited our attention to the common interval 1926–2003 (78 years) in which the response of the tree-ring chronologies to climate at both local and regional scale was investigated. Positive moisture balance in the late spring-summer period of the year of growth is the climatic driver of P. pinea radial growth in the study area. Moreover, this study shows how low summer temperatures strongly favor the radial growth of the species.     

Lost writing uncovered by laser two-photon fluorescence provides a terminus post quem for Roman colonization of Hispania Citerior

In this work, two-photon absorption fluorescence is used as a non-destructive method to detect the presence of paint upon an archaeological sample. The objective was to recover writing that, due to the discoloration caused by the passage of the time, was barely readable. The technique has been successfully applied to determine the consular date painted upon the neck of a Dressel 1A amphora found in the Roman village of Iesso (Guissona), in Catalonia. The identification of the consular date provides a terminus post quem for the foundation date for the city as well as a starting date for the Roman colonization of Hispania Citerior.     

Cuban Miami on the Air: Narratives of Cubanía

Radio has been a fundamental aspect of Cuban culture on and off the island since the first broadcast in Havana in 1922. When Cubans fled the island after the revolution of 1959 for the USA, particularly Miami, radio quickly became a vital medium for navigating a new country and for consolidating a Cuban exile identity. Politically, radio in Miami has been an effective means for articulating hardline exile politics. But with generational turnover and increasingly moderate stances on Cuba by more recent arrivals and US-born Cuban Americans, how is radio changing? How are narratives of what constitutes cubanía – Cubanness – shifting in an increasingly diverse Cuban Miami? This article takes up these questions through an examination of an immensely popular morning program that aired in 2009 in southern Florida called the Enrique y Joe Show. I examine how the Enrique y Joe Show, produced and performed by US-born Cuban Americans, utilized a form of irreverent Cuban humor called choteo to represent and satirize the hardline Cuban exile politics that have been dominant on Miami's radio waves for decades. Ultimately, their performances deploy choteo to articulate Cuban American identity divorced from a particular political orthodoxy. The coda reflects on changes in Miami's radio landscape since 2009.     

Review of Out-of-Plane Seismic Assessment Techniques Applied To Existing Masonry Buildings

ABSTRACT

Observations after strong earthquakes show that out-of-plane failure of unreinforced masonry elements probably constitutes the most serious life-safety hazard for this type of construction. Existing unreinforced masonry buildings tend to be more vulnerable than new buildings, not only because they have been designed to little or no seismic loading requirements, but also because connections among load-bearing walls and with horizontal structures are not always adequate. Consequently, several types of mechanisms can be activated due to separation from the rest of the construction. Even when connections are effective, out-of-plane failure can be induced by excessive vertical and/or horizontal slenderness of walls (length/thickness ratio). The awareness of such vulnerability has encouraged research in the field, which is summarized in this article. An outline of past research on force-based and displacement-based assessment is given and their translation into international codes is summarized. Strong and weak points of codified assessment procedures are presented through a comparison with parametric nonlinear dynamic analyses of three recurring out-of-plane mechanisms. The assessment strategies are marked by substantial scatter, which can be reduced through an energy-based assessment.     

The Trencadis Mosaic on the Pinnacles of the Sagrada Familia Cathedral

The architect Antoni Gaudí developed a unique constructive solution for the pinnacles that crown his last work, the Sagrada Familia. It consisted of fashioning the finishing components from precast pieces of lightly reinforced concrete that was covered with a trencadis mosaic of Murano glass. With this solution, Gaudí invented a singular coating material that responded to the special ambient conditions of a construction at great height, keeping esthetic and decorative aspects in mind. Those who have continued his work up to this day still employ this constructive system to complete the new pinnacles and in the decoration of other parts of the cathedral. The main objective of this study is to explain the conception and the constructive logic of the Sagrada Familia pinnacles, as well as its evolution since the beginning of the 20th century. For that focus, a review of the way in which Gaudí applied the trencadis coating in his earlier works is presented. Likewise, the reasons that led the architect to select a unique glass imported from Italy for the trencadis on the temple pinnacles are revealed.     

Electoral rule and public sector efficiency: Some evidence from Italian municipalities

We study the effect of Law 81/1993, which introduced a different rule for the election of mayors, on the technical efficiency of Italian cities over the period 1998–2006. Since 1993, municipalities below 15,000 inhabitants vote with a single-ballot system, whereas cities above 15,000 inhabitants are subject to a double ballot. We first estimate the output-oriented technical efficiency of municipalities through data envelopment analysis, and then we perform a regression discontinuity design analysis by exploiting the exogenous change in the electoral scheme at the 15,000 inhabitants cut-off. We find evidence that municipalities voting under a double-ballot rule show lower levels of efficiency—in terms of provision of public goods—compared with cities voting under a single-ballot scheme, by about 6.5%. This effect is driven by inefficiencies registered in specific sectors, that is, police, education, and maintenance of roads. Furthermore, the overall lower efficiency of municipalities voting under runoff is related to the different level of educational attainment of elected mayors, whereas it is not driven by the features of Law 81/1993 relating to the number of lists forming a coalition in support of mayoral candidates and to disjoint votes.
