Political determinants of the fiscal sustainability: evidence from six individual developed countries.

2007

This paper aims at assessing the fiscal sustainability and its political determinants in six countries, namely France, Germany, Greece, Italy, the United Kingdom, the United States. First, using the recent sustainability approach of Bohn (1998) based on fiscal reaction function, econometric findings using OLS reveal a positive response of the primary surplus to changes in debt in several countries. In other words, fiscal policy is sustainable in France, Italy, the United Kingdom, the United States, but not in Germany and Greece. Second, by introducing political dummy variables, we test the electoral budget cycle, the partisan cycle and the government coalition theories. We find the presence…

Cyclicity of Triassic to Lower Jurassic continental red beds of the Argana Valley, Morocco: implications for palaeoclimate and basin evolution

2000

Abstract Cyclical playa deposits form a prominent part of the continental clastic succession of the Argana Valley, Western High Atlas of Morocco. The red beds formed in Triassic to Lower Jurassic times during rifting of the North American and African plates. Detailed stratigraphic work revealed asymmetrical, metre-scale cycles in mudstone-dominated successions that constitute the intermediate and upper portion of the basin fill. Sedimentary cycles commonly comprise ephemeral lake shales at the base, playa mudflat mudstones in the intermediate part, and both fluvial and aeolian sandstones at the top. Cycles of the Aglegal Member (T4) are mainly characterized by analcime-rich playa mudflat de…

Exergy recovery during LNG regasification: Electric energy production – Part one

2009

Abstract In liquefied natural gas (LNG) regasification facilities, for exergy recovery during regasification, an option could be the production of electric energy recovering the energy available as cold. In a previous paper, the authors propose an innovative process which uses a cryogenic stream of LNG during regasification as a cold source in an improved combined heat and power (CHP) plant. Considering the LNG regasification projects in progress all over the World, an appropriate design option could be based on a modular unit having a mean regasification capacity of 2 × 109 standard cubic meters/year. This paper deals with the results of feasibility studies, developed by the authors at DRE…

Role of Stress History on the Swelling-Shrinkage Behavior of Compacted Scaly Clay

2022

Compacted scaly clays are complex geomaterials widely used for the realization of dam cores and waste dump liners. This research aims to investigate the swelling/shrinkage behavior of these geomaterials subjected in an oedometric cell to complex hydromechanical stress paths, including different sequences of cyclic variations of suction and stress. Microstructure investigations, based on scanning electron microscopy (SEM) and mercury intrusion porosimetry (MIP) techniques, highlighted the microstructural characteristics of the material, which are the distinctive microfabric features (particles assemblages and scales) and the double-porosity networks, where micro- and macropores coexist.

Sine cura. Verso il ri-ciclo dell'architettura del secondo Novecento

2019

Gli argomenti discussi nel saggio interrogano il destino che il Codice dei Beni Culturali (2004- 2011) determina per le opere del secondo Novecento. Nella costruzione del futuro di questi manufatti, che per funzione, tecnologia e cicli d’uso sono spesso segnati dall’obsolescenza e dall’abbandono, le ambiguità e le incongruenze delle attuali procedure legislative sollecitano profondamente il ruolo culturale delle esperienze di ricerca che usano metodologie meta progettuali. Il confronto fra alcuni casi italiani ed altri europei rimarca il ruolo del progetto nella costruzione di una prospettiva di tutela trasformativa per il costruito del secondo Novecento. Nel quadro di azione marcato dall’o…

Settore ICAR/14 - Composizione Architettonica E UrbanaThe essay questions the future's possibilities to operate on the buildings of the second half of the twentieth century according to the Italian Code of Cultural Heritage (2004-2011). When arguing how to encourage the re-use of these artifacts which are often marked by short-life technology cycles obsolescence and abandonment the ambiguities and inconsistencies of current legislative procedures deeply stress the cultural role of research experiences that use project-oriented methodologies. The comparison between some Italian and other European cases highlights the role of a design approach in the construction of a transformative protection perspective for the built matter of the second half of the twentieth century. In a framework aiming to encourage a reconciliation between the recent built environment and the new paradigms of sustainability and circular economy architecture must recognize re-cycle practices as a main theoretical and procedural node. To modernize the late Modern built environment with contemporary construction components is not simply a matter of technical knowledge and expertise: but a theme with theoretical density aesthetic and ethical values. The architectural project in this field today must ask for greater congruence between the bureaucratic and administrative levels and the real consistency of this corpus. It is a matter of identifying strategies to equip it with capabilities meanings and contents remembering that demolition wastes have unsustainable environmental costs and uncertain results concerning the necessary new attribution of political and semantic meaning that these places await.

Labor Market Imbalances and Personnel Recruitment

2019

When the economy of a country starts to expand or collapse in wealth, it is reflected in the labor market with an impact on employment and personnel recruitment processes. The aim of this article is to investigate the relationship between personnel recruitment and job market imbalances in the various de- velopmental conditions of the macroeconomic environment. Research find- ings show that employers tend to adopt more active, formal, competitive, targeted, and selective search behaviors in the positive cycles of the economy and employment. Conversely, in downturns of the economy and employ- ment, employers tend to be more passive and defensive, relying on informal relationships and, in some…

Sequence stratigraphy of a mesozoic carbonate platform-to-basin system in Western sicily

2009

Abstract Sequence stratigraphic studies of the Triassic through Paleogene carbonate successions of platform, slope and basin in western Sicily (Palermo and Termini Imerese Mountains) have identified a sedimentary cyclicity mostly caused by relative oscillations of sea level. The stratigraphic successions of the Imerese and Panormide palaeogeographic domains of the southern Tethyan continental margin were studied with physical-stratigraphy and facies analysis to reconstruct the sedimentary evolution of this platform-to-basin system. The Imerese Basin is characterized by a carbonate and siliceous-calcareous succession, 1200–1400m thick, Late Triassic to Eocene in age. The strata display a typ…

BIOCHARS IN SOILS: TOWARDS THE REQUIRED LEVEL OF SCIENTIFIC UNDERSTANDING

2017

The special issue on Biochar as an Option for Sustainable Resource Management Key priorities in biochar research for future guidance of sustainable policy development have been identified by expert assessment within the COST Action TD1107. The current level of scientific understanding (LOSU) regarding the consequences of biochar application to soil were explored. Five broad thematic areas of biochar research were addressed: soil biodiversity and ecotoxicology, soil organic matter and greenhouse gas (GHG) emissions, soil physical properties, nutrient cycles and crop production, and soil remediation. The highest future research priorities regarding biochar’s effects in soils were: functional …
