Productivity spillovers and regional differences: some evidence on the italian manufacturing sector

This work examines the main theoretical and empirical interpretations regarding the effects of foreign direct investment on productivity of local firms and, in particular, in which way productivity spillovers are related to the existence of regional differences. By taking into consideration the Italian manufacturing sector and using cross-section data, we find that although at a national level productivity levels are higher in the domestic sectors where multinational firms account for larger shares, productivity spillovers are concentrated only in the north-western area of Italy.foreign direct investment; productivity spillovers

Banking System Efficiency and the Dualistic Development of the Italian Economy in the Nineties

The article provides an analysis of some features of the Italian Credit System in the Nineties. In particular, it focuses on a comparison of Banks efficiency – in terms of costs, revenues and profits – in Northern and Southern Italy taking into account the dualistic structure, which characterizes the Italian economic system.

Exporting quality: is it the right strategy for the Italian manufacturing sector?

ABSTRACT: Recently, most European manufacturing firms have been engaged in a number of innovative activities to survive the growing competition coming from newly-industrialising countries. Italian manufacturing industry, which relies largely on SMEs, is struggling to regain competitiveness in global markets. In light of these stylised facts, we first investigate whether innovating activities and quality goods’ production enhance Italian SMEs’ probability to be exporter. Our findings suggest that both products’ quality and innovative activities affect considerably SMEs’ likelihood to export. Subsequently, using the Chow test, we find evidence for a structural break produced by quality, which results in substantial differences between high and low-quality firms. The former are more likely to export if they introduce product innovation, marketing innovation and/or organisational changes, the latter increase their chances of exporting when introducing process innovations and organisational changes.SMEs, exports, innovative activities, quality, probit

LA GIUSTIZIA TRIBUTARIA TRA SPECIALITÀ ED ORDINARIETÀ

Il contenzioso tributario negli ultimi anni è stato in costante crescita ,sia dal punto di vista del valore economico, che del numero dei procedimenti; d'altronde la rilevante percentuale di ricorsi per Cassazione evidenzia con chiarezza come tale tipo di contenzioso , che nella sua specificità non è soggetto ad alcun limite di competenza, abbia ormai un suo ruolo autonomo da tutti riconosciuto. Alla vigilia dell’annunciata riforma della Giustizia Tributaria può pertanto essere opportuna una valutazione della problematica nell'ambito di una analisi sia economica, per ciò che attiene ai problemi di efficienza e di produttività del sistema (al fine di evitare o almeno di limitare i cd "fallimenti di mercato"), sia giuridica , in considerazione degli aspetti procedurali propri del sistema stesso; inoltre una comparazione con l'esperienza di altri Paesi che hanno giurisdizioni vicine alla nostra può facilitare la individuazione di best practices da utilizzare. In tale ottica complessiva si cercherà di evidenziare quali modifiche e nuovi meccanismi procedurali possono concorrere a migliorare la qualità del sistema, con particolare attenzione alla fase che precede il giudizio, la quale a nostro avviso riveste una rilevanza significativa

Magnesium isotopes: a tool to understand self-enrichment in Globular Clusters

A critical issue in the asymptotic giant branch (AGB) self-enrichment scenario for the formation of multiple populations in Globular Clusters (GCs) is the inability to reproduce the magnesium isotopic ratios, despite the model in principle can account for the depletion of magnesium. In this work we analyze how the uncertainties on the various p-capture cross sections affect the results related to the magnesium content of the ejecta of AGB stars. The observed distribution of the magnesium isotopes and of the overall Mg-Al trend in M13 and NGC 6752 are successfully reproduced when the proton-capture rate by 25Mg at the temperatures 100 MK, in particular the 25Mg(p, gamma)26Alm channel, is enhanced by a factor 3 with respect to the most recent experimental determinations. This assumption also allows to reproduce the full extent of the Mg spread and the Mg-Si anticorrelation observed in NGC 2419. The uncertainties in the rate of the 25Mg(p,gamma)26Alm reaction at the temperatures of interest here leave space for our assumption and we suggest that new experimental measurements are needed to settle this problem. We also discuss the competitive model based on the super massive star nucleosynthesis.Comment: accepted for publication on MNRA

Pleural mesothelioma: Case-report of uncommon occupational asbestos exposure in a small furniture industry

The relationship between asbestos exposure and malignant mesothelioma is no longer disputed, although it is not always easy to trace past occupational exposure. This report describes a case of uncommon asbestos exposure of a small furniture industry worker, who subsequently died of pleural malignant mesothelioma, to stress the crucial importance of a full reconstruction of the occupational history, both for legal and compensation purposes. Sarcomatoid pleural mesothelioma was diagnosed in a 70-year-old man, who was previously employed as a carpenter in a small furniture industry. He worked for about 6 years in the small factory, was exposed to asbestos during the assembly of the furniture inspired by classical architecture, in which asbestos cement tubes were used to reproduce classical columns. During this production process no specific work safety measures were applied, nor masks or local aspirators. No extra-professional exposure to asbestos was identified. This mesothelioma case was investigated by the Public Prosecutor's assignment that commissioned expert evidence on the legal accountability for the disease. Despite its uncommon expositive circumstance, the length of latency (about 30 years), the duration of exposure, the clinical and histochemical features are all consistent with literature evidence, accounting for the occupational origin of this malignancy

Contrast enhanced ultrasound in the assessment of urogenital pathology

Contrast enhanced ultrasound (CEUS) is an innovative technique that employs microbubble contrast agents to demonstrate parenchymal perfusion. Although initial clinical application was focused on the liver pathology, a wide variety of clinical conditions can be assessed now with CEUS. CEUS is a well-tolerated technique and is acquiring an increasing role in the assessment of renal pathology because contrast agents are not excreted by the kidney and do not affect the renal function. CEUS demonstrated an accuracy similar to contrast enhanced multi-detector computed tomography (CEMDCT) in detecting focal lesions, with the advantage of the real-time assessment of microvascular perfusion by using time-intensity curves. The aim of this paper is to review the main indications of CEUS in the assessment of renal and urogenital pathology. Imaging examples are presented and described. Advantages and limitations of CEUS with reference to conventional US and CE-MDCT are discussed

Massive Star Evolution: Nucleosynthesis and Nuclear Reaction Rate Uncertainties

We present a nucleosynthesis calculation of a 25 solar mass star of solar composition that includes all relevant isotopes up to polonium. In particular, all stable isotopes and necessary nuclear reaction rates are covered. We follow the stellar evolution from hydrogen burning till iron core collapse and simulate the explosion using a ``piston'' approach. We discuss the influence of two key nuclear reaction rates, C12(a,g) and Ne22(a,n), on stellar evolution and nucleosynthesis. The former significantly influences the resulting core sizes (iron, silicon, oxygen) and the overall presupernova structure of the star. It thus has significant consequences for the supernova explosion itself and the compact remnant formed. The later rate considerably affects the s-process in massive stars and we demonstrate the changes that different currently suggested values for this rate cause.Comment: 6 pages, including 4 PostScript figures, to appear in Proc.
