The ripple effects of large-scale transport infrastructure investment

We analyze the general equilibrium effects of an asymmetric decrease in transport costs, combining a large-scale spatial dynamic general equilibrium model for 267 European NUTS-2 regions with a detailed transport model at the level of individual road segments. As a case study, we consider the impact of the road infrastructure investments in Central and Eastern Europe of the European Cohesion Policy. Our analysis suggests that the decrease in transportation costs benefits the targeted regions via substantial increases in gross domestic product (GDP) and welfare compared to the baseline, and a small increase in population. The geographic information embedded in the transport model leads to relatively large predicted benefits in peripheral countries such as Greece and Finland, which hardly receive funds, but whose trade links cross Central and Eastern Europe, generating profit from the investments there. The richer, Western European nontargeted regions also enjoy a higher GDP after the investment in the East, but these effects are smaller. Thus, the policy reduces interregional disparities. There are rippled patterns in the predicted policy spillovers. In nontargeted countries, regions trading more intensely with regions where the investment is taking place on average benefit more compared to other regions within the same country, but also compared to neighboring regions across an international border. We uncover that regions importing goods from Central and Eastern Europe enjoy the largest spillovers. These regions become more competitive and expand exports, to the detriment of other regions in the same country.     

The origin of the term plasticity in the neurosciences: Ernesto Lugaro and chemical synaptic transmission

The Italian psychiatrist Ernesto Lugaro can be regarded as responsible for introducing the term plasticity into the neurosciences as early as 1906. By this term he meant that throughout life the anatomo-functional relations between neurons can change in an adaptive fashion to enable psychic maturation, learning, and even functional recovery after brain damage. Lugaro's concept of plasticity was strongly inspired by a neural hypothesis of learning and memory put forward in 1893 by his teacher Eugenio Tanzi. Tanzi postulated that practice and experience promote neuronal growth and shorten the minute spatial gaps between functionally associated neurons, thus facilitating their interactions. In addition to discovering the cerebellar cells known by his name and advancing profound speculations about the functions of the glia, Lugaro lucidly foresaw the chemical nature of synaptic transmission in the central nervous system, and was the first to propose the usage of the terms "nervous conduction" and "nervous transmission" in their currently accepted meaning.     

Use of ground penetrating radar to map subsurface archaeological features in an urban area

The ground penetrating radar (GPR) technique was used to investigate the subsurface in an urban area located in Mesagne (Italy) to obtain a map of the archaeological features in the ground. The GPR survey was undertaken at selected locations placed near (about 50 m) to a necropolis dating from the Messapian to the Roman imperial age, using a GSSI Sir System 2 incorporating 200 and 500 MHz centre frequency antennae. The selected areas (A and B) were surveyed along parallel 1 m spaced profiles using a 200 MHz antenna in area A and along parallel 0.5 m spaced profiles using a 500 MHz antenna in area B. For the selected areas the processed data were visualised in 3D space not only by means of the standard time slice technique, but also by means of a recently proposed approach, namely by iso-amplitude surfaces of the complex trace amplitude. The immediacy in revealing the spatial positioning of highly reflecting bodies, such as the anomaly interpreted as an old hypogeum room in area A, makes 3D visualisation techniques very attractive in archaeological applications of GPR. Their sensitivity to the signal/noise ratio is, on the other hand, highlighted by the quite poor performance in area B, where the only reliable result provided by all the techniques was the ancient living surface reflection, whereas none of them could effectively enhance the visibility of weak hyperbola reflections noted on 2D sections and probably related to the walls located on the ancient living surface. The performance of the various techniques in these two different situations allowed insights into their main advantages and drawbacks to be gained.

A “Calvinist” theory of matter? Burgersdijk and Descartes on res extensa

In the Dutch debates on Cartesianism of the 1640s, a minority believed that some Cartesian views were in fact Calvinist ones. The paper argues that, among others, a likely precursor of this position is the Aristotelian Franco Burgersdijk (1590-1635), who held a reductionist view of accidents and of the essential extension of matter on Calvinist grounds. It seems unlikely that Descartes was unaware of these views. The claim is that Descartes had two aims in his Replies to Arnauld: to show the compatibility of res extensa and the Catholic transubstantiation but also to differentiate the res extensa from some views of matter explicitly defended by some Calvinists. The association with Calvinism will be eventually used polemically against Cartesianism, for example in France. The paper finally suggests that, notwithstanding the points of conflict, the affinities between the theologically relevant theories of accidents, matter and extension ultimately facilitated the dissemination of Cartesianism among the Calvinists.     

Contribution of Ground Penetrating Radar and Electrical Resistivity Tomography to identify the cavity and fractures under the main Church in Botrugno (Lecce,Italy)

The “Chiesa Matrice” is the main Church of Botrugno village, located about 70 km south-east of Lecce (Italy). The church was built between the end of 1500 BC and the beginning of 1600 BC.     

Revisiting the 1981 Nobel Prize to Roger Sperry, David Hubel, and Torsten Wiesel on the occasion of the centennial of the Prize to Golgi and Cajal

In 1981 the Nobel Prize for Medicine or Physiology was awarded to Roger Sperry for his work on the functional specialization of the cerebral hemispheres, and to David Hubel and Torsten Wiesel for their work on information processing in the visual system. The present paper points to some important links between the work of Sperry and that of Hubel and Wiesel and to their influences on neuroscience in the best tradition going back to Cajal.     

Social Funds in Stabilization and Adjustment Programmes: A Critique

This article evaluates the impact of the large number of Social Funds (SFs) which were introduced over the last fifteen years to offset the increase in poverty induced by adjustment. SFs have enjoyed greater visibility and financial support by the donor community than traditional social security programmes, and raised expectations about improvements in living conditions in developing countries. Notwithstanding the visibility and administrative flexibility they enjoyed, and their fairly rapid implementation, SFs played only a minor role in reducing the number of adjustment poor and chronic poor and reversing adverse shifts in income distribution. This was due to problems in funding, targeting and sequencing, and cost‐effectiveness. The article concludes that, all in all, SFs have proven to be no panacea. Many of them were formulated with the political objective of reducing domestic opposition to the adjustment process. Greater impact on poverty would have required increased resources, more permanent relief structures, improved planning and targeting and, especially, better timing in relation to the fiscal cuts entailed by macroeconomic adjustment.
