Italy says no: the 2016 constitutional referendum and its consequences

On 4 December 2016, Italians went to the polls to say yes or no in a popular referendum called by Prime Minister Matteo Renzi on his package of constitutional reforms. Turnout was very high: 65.5 per cent. The No vote scored an impressive victory: 59.1 per cent rejected those reforms; 40.9 per cent supported them. This article puts those reforms in the context of previous attempts to modify several articles of the Italian constitution. The authors analyze and criticize the substance of those reforms and explain their possible impact on the functioning of the Italian political system. The Yes and No alignments were somewhat diversified, while the Yes vote got a lot of support from an often curious combination of domestic and foreign bedfellows interested in the political stability of Renzi’s government more than in any specific reform. Renzi’s defeat led to his resignation. A new government was immediately formed. It is unclear when and whether other, different constitutional reforms will be formulated. The Italian political and institutional transition continues while once again attention is focused on the electoral law and on how to restructure the parties and the party system.     

Archaeometric study of natural hydraulic mortars: the case of the Late Roman Villa dell’Oratorio (Florence,Italy)

This paper shows the results of a multidisciplinary study carried out on the mortars from the Late Roman Villa dell’Oratorio (fourth-sixth ad), an aristocratic mansion built in the lower Valdarno (Florence, Italy). Thirty-one bedding mortar and plaster samples were analysed through optical microscopy, thermogravimetric analysis, X-ray powder diffraction and scanning electron microscopy with energy-dispersive X-ray spectroscopy for determining the chemical, mineralogical and petrographic characteristics, while their main physical properties were measured by geotechnical procedures. The collected data indicates that the analysed mortars are made up of very fine to coarse river sand aggregate mixed with white to yellowish-white natural hydraulic lime binder mainly consisting of mixtures of prevailing calcite and hydraulic compounds. With regard to the origin of the raw materials, the aggregates were recognized to be selected Arno river sands, and the binders are the burning product of a local marly limestone (ex Alberese). Therefore, the mortars of the Late Roman Villa dell’Oratorio are one of the first uses of natural hydraulic lime in the lower Valdarno.     

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.     

Visual images in Luigi Galvani's path to animal electricity

The scientific endeavor that led Luigi Galvani to his hypothesis of "animal electricity," i.e., of an electricity present in a condition of disequilibrium between the interior and the exterior of excitable animal fibers, is reviewed here with particular emphasis to the role played by visual images in Galvani's path of discovery. In 1791 Galvani formulated his model of neuromuscular physiology on the base of the image of a muscle and a nerve fiber together as in a "minute animal Leyden jar." This was the last instance of a series of physical models that accompanied Galvani's experimental efforts in the search of a theory capable of accounting for the electric nature of nerve conduction in spite of the many objections formulated in the eighteenth century against a possible role of electricity in animal physiology.     

“Kontakte” – Reflexionen naturwissenschaftlich‐technischer Innovationsprozesse in der frühen Elektronischen Musik Karlheinz Stockhausens (1952–1960)

“Kontakte” – Reflections of Innovative Processes in Science and Technology in Karlheinz Stockhausen's Early Electronic Music (1952–1960). The following article will give an overview of the interdependence of aesthetic and scientific/technical developments in German composer Karlheinz Stockhausen's early works of electronic music. It is an outline of the major steps in his artistic evolution between the works “Etude (Musique concrète)” and “Kontakte”, their relation to innovations in psychoacoustic and sound‐studio technology as well as the impact, that the works from that period had on the fundamental changes in musical aesthetics during the course of the 20th century.     

Microstructures of Building Materials from Huaca De La Luna,Peru

ABSTRACT

The microstructures of building materials from the archaeological complex of Huaca de la Luna on the northern coast of Peru is assessed for the first time by a multiscale approach. The multiscale microstructural characterization used laboratory techniques including optical microscopy, scanning electron microscopy, X-ray microtomography, and both gas and powder pycnometry. Optical microscopy revealed the presence of organic matter and shell fragments and X-ray microtomography showed differences in the sizes and connectivity of pores. The BET (N₂ gas adsorption) specific surface areas showed greater presence of clayey matrix in the mortars. No significant differences among mortars and brick fragments mineralogy were detected by X-ray diffraction, so the larger amount of fine binding matrix in the mortars suggests that they were produced blending raw material with different grain sizes. The aim of this study is to provide data that can be used for a better understanding of the Moche culture, its construction techniques, and to support conservation strategies of the archaeological heritage.     

What is the Alternative? Youth,Entrepreneurship and the Developmental State in Urban Ethiopia

This article investigates the implementation of small‐scale entrepreneurship programmes in inner‐city Addis Ababa. Drawing on eighteen months of ethnographic fieldwork, it discusses the failure of these programmes to open up opportunities for social improvement for young people. It also analyses how young people confronted with this failure suggest ways of conceptualizing ‘alternatives’ to established development concepts of poverty reduction, such as microfinance and small‐scale entrepreneurship. In doing this, the author does not pretend either to offer a grand solution or to invent a brand new developmental concept. Rather, the aim is to provide a critical commentary on the reasons why some of the current academic debate on alternatives to neoliberalism have, de facto, amounted to an endorsement Ethiopia's political authoritarianism.
