Business Cycle Synchronization of CEECs with the Euro Area: A Regime Switching Approach
No full textThis article investigates the possible business cycle linkages between CEECs (Central and Eastern
European countries) that were candidates to enter the EMU and the euro area for the period 1993 to
2014. We analyse business cycle (a)symmetries for these countries by using Markov switching
autoregressive models and synchronization tests. By analysing the correlations between the cyclical
fluctuations for these countries, we examine the existence of common features between the individual
cycles. By distinguishing between different regimes, we show that the indications of
business cycle synchronization are quite high in the recession regime, but lower in the normal
and high growth regimes, with the exceptions of Hungary and Poland
Isteresi, domanda aggregata, trend stocastici comuni in un modello di range di tassi di disoccupazione di equilibrio
Full text linkNegli ultimi decenni molte economie europee hanno sofferto di persistenti alti tassi di disoccupazione, generalmente considerati come il risultato combinato di shock macroeconomici e rigidità istituzionali. In tale contesto, il fenomeno dell’isteresi significa che shock temporanei danno luogo a variazioni permanenti nel livello di disoccupazione, il cui risultato è la forte dipendenza dalla sua storia passata, che assume così la forma di path-dependence. Questo fenomeno
comporta mutamenti del NAIRU, ma anche che, sotto certe condizioni di funzionamento dei mercati, possano
verificarsi equilibri multipli macroeconomici connessi con un range di tassi di disoccupazione di equilibrio. Da ciò ne consegue che politiche di demand managment esercitano effetti reali permanenti sull’output e sulla disoccupazione anche nel lungo periodo, determinando persistenza nel tasso di disoccupazione e causando la possibilità di passaggi da un equilibrio stazionario ad un altro entro il range dei NAIRU. Nel lavoro si analizzano i fatti stilizzati del mercato del lavoro italiano, tentandone un’interpretazione sulla base di un modello VAR strutturale con vincoli di cointegrazione, dal quale ne deriva una rappresentazione di common stochastic trends in cui si studia il comportamento del sistema sia
nelle sue componenti cicliche che permanenti. Vengono esaminate le evoluzioni dinamiche di breve e lungo periodo del sistema. Shock temporanei ai trend stocastici hanno effetti permanenti, mentre fluttuazioni di breve periodo sono guidate sia da shock di trend che da shock puramente transitori. In tal senso, le componenti cicliche e strutturali della
disoccupazione sono correlate, ma anche distinguibili
The influence of plasma on the morphological and structural properties of TiO2 thin films
No full textUniform and dense titanium dioxide (TiO2) thin films, required in several fields, can be achieved by using standard deposition. Here, we investigate the effect of using a plasma source during e-beam deposition on the morphological and structural properties of TiO2 thin films. We show that morphology, crystallization onset temperature, and crystallization evolution are all affected by the change in
material density, achieved by employing or not plasma bombardment
A new model of acute care hospitals and the role of nephrologists.
No full textOver the last decade, the Italian National Health Service has been widely criticized for failing to meet the expectations of the Italian population and to reduce the weaknesses of the health care system deriving from a lack of balance between increasing costs and comparable benefits. In order to improve health care services, a new model of acute care hospitals, characterized mainly by new structures, high technology, integration and collaboration among professionals, are necessary. The traditional concept of specialized operative unit is thus overcome by a new hospital organization in which specific functions are performed in shared facility areas. In particular, the role of the nephrologists will be reorganized into different health care settings according to the level of intensity of care: high level (intensive care unit, organ transplantation), intermediate level (medical area) or low intensity care facilities (day hospital, day surgery, day service, ambulatory)
A comparison of the Beveridge curve dynamics in Italy and USA
Full text linkIn this article, we investigate the Beveridge curve dynamics in the USA and Italy by means of a cointegrated structural VAR model. A simple economic model is introduced to motivate the identifying assumptions of the empirical analysis. A stable long-run relationship is found for both countries. In order to study the dynamic behaviour of the model, and to decompose unemployment and vacancy fluctuations, we identify three common stochastic trends. The empirical results suggest that there are some sources of hysteresis in unemployment in both countries. Transitory shocks are also identified to account for the short-run dynamics of the model. The approach allows us to detach the long-run from the short-run dynamics, in order to provide information on the cyclical and structural Beveridge curve

Circular economy strategies for adaptive reuse of Borgo San Leonardo in Carlentini
No full textReuse of the built heritage is a strategy for enhancing the architectural heritage, designed to start virtuous development processes with positive impacts on the landscape. Adaptive reuse is a significant approach in circular economy practices to extend the life cycle of building by lengthening the use and delaying the end of life. As a result, the reuse of abandoned buildings can enhance the surrounding contexts, achieving ecological benefits and implementing social responsible economic growth. Borgo San Leonardo in Carlentini (Italy) is an example of disused rural heritage in a context of high landscape value and development potential, characterised by a common type of dwelling in the Syracuse area. The area has been declared of outstanding public interest and still retains its perceptual-cultural, morphological-dimensional, and material-constructive values. The regeneration of rural heritage seeks to place communities at the centre of decision-making processes in these territories, aiming to preserve the local productive culture and traditions while activating new development processes. The case study describes the decision-making process related to the definition of new uses, through a multi-criteria and participatory approach. The outcomes are guidelines to choose new compatible uses for old buildings, able to activate circular development processes. This will be achieved through a Multi-Criteria Decision Analysis (MCDA), in order to compare adaptive reuse alternatives, considering the impacts on the environmental, cultural, social and economic systems
Uric acid: a starring role in the intricate scenario of metabolic syndrome with cardio-renal damage?
No full textElevated uric acid levels are a common finding in patients with metabolic syndrome and in those with cardiovascular and renal disease, but the meaning of this elevation is still unclear. In patients with chronic kidney diseases, it could merely reflect the reduction in glomerular filtration rate: but uric acid levels are known to be elevated in people, also in younger ones, prior to the development of hypertension or renal disease, independently of several risk factors. Multiple potential mechanisms suggest a causative role for uric acid in vascular disease. Uric acid has been shown to be involved in metabolic pathways that lead to oxidative stress, endothelial disfunction, and to a vascular and systemic inflammatory response. Moreover, the elevation in uric acid levels observed after fructose ingestion, with a consequent reduction in nitric oxide, may lead to a reduced glucose uptake in the skeletal muscle, hyperinsulinemia, and insulin resistance. Besides these bench research data, also clinical studies showed the beneficial effects of lowering uric acid therapies on several markers of cardiovascular and renal disease. To date, however, there is no evidence indicating that such therapies, that are not free of risk, may reduce cardiovascular events; so that to manage our prescriptions, we need larger, prospective, interventional data
