Forecast Output Coincidence and Biproportion: Two Criteria to Determine the Orientation of an Economy. Comparison for France (1980-1997)
2002
International audience; The method of forecast output coincidence used to determine if sectors are demand-sided or supply-sided in an input-output framework mixes two effects, the structural effect (choosing between demand and supply side models) and the effect of an exogenous factor (final demand or added-value). The note recalls that another method is possible, the comparison of the stability of technical and allocation coefficients, generalized by the biproportional filter: if for a sector, after biproportional filtering, column coefficients are more stable than row coefficients, then this sector is declared as not supply-sided (but one cannot decide that it is demand-sided anyway), and …
Bitcoin e cyber self-laundering: lo sguardo sospettoso della Cassazione sull'impiego di criptovaluta
2023
In Judgment n. 27023 of 2022, the italian Supreme Court recognized the confgurability of the crime of self-money laundering in the conduct of a person who uses the proceeds of crimes committed by him to purchase bitcoin, not directly, but through the intermediation of cryptocurrency exchange companies. The Author takes the pronouncement as a starting point to probe the extent to which the culture of suspicion, with which the anti-money laundering legislation is imbued, and the stigmatization of cryptocurrency have influenced the Supreme Court's guidance, in which there emerges a strong temptation to establish a kind of automatism between the input of illicit proceeds into the bitcoin system…
Bitcoin e rivoluzione digitale internazionale. Note a margine di una sentenza della United States District Court of Columbia.
2021
This Note is about the recent recognition, by the United District Court of Columbia, of bitcoin as 'money'. The Note offers a brief insight of the decision and some reflections on the actual international digital revolution and the current threats/opportunities related to it.
Blockchain Securities, Insolvency Law and the Sandbox Approach
2018
Blockchain is a new technology that is based on an algorithm which allows participants of an IT network to process, store and share data across multiple points without the need for any intermediary, at least in order to ensure the integrity of the data dealt with. This technology is simplifying financial markets—many organizations are launching initial coin offerings to facilitate the financing of new business ventures; moreover, ‘securities’ that are issued in such a digital form can be bought and sold in the secondary market without the intervention of the traditional intermediaries. However, this use of blockchain could give rise to many problems which, in this article, will be analysed …
Physiological and agonistic behavioural response of Procambarus clarkii to an acoustic stimulus
2012
Summary This study examined the effects of an acoustic stimulus on the haemolymph and agonistic behaviour of the red swamp crayfish Procambarus clarkii. The experiment was conducted in a tank equipped with a video recording system using 6 groups (3 control and 3 test groups) of five adult crayfish (30 specimens in total). After one hour of habituation, the behaviour of the crayfish was monitored for two hours. During the second hour, the animals in the test groups were exposed to a linear sweep (frequency range 0.1-25 kHz; peak amplitude 148 dBrms re 1 µPa at 12 kHz) acoustic stimulus for 30 minutes. Exposure to the noise produced significant variations in haemato-immunological parameters a…
Differential expression of the corticosteroid receptors GR1, GR2 and MR in rainbow trout organs with slow release cortisol implants
2012
The present study describes the transcriptional levels of the corticosteroid receptors (CRs) GR1, GR2 and MR in the different organs of the rainbow trout (Oncorhynchus mykiss) in response to a slow release of cortisol, throughout a 10-day period. We show that after short term (1 day after cortisol implantation), when the plasma levels of cortisol emulate an acute stress, the GR2 and MR expression levels were upregulated in the brain and head kidney tissues. This result reflects the role of these organs as regulators of the stress response. In general, the rest of the organs, especially gills, intestine, liver, muscle and spleen, showed decreased transcriptional levels of GR1, GR2 and MR, al…
Profiling the physiological and molecular response to sulfonamidic drag in Procambarus clarkii
2014
Sulfamethoxazole (SMZ) is one of the most widely employed sulfonamides. Because of the widespread use of SMZ, a considerable amount is indeed expected to be introduced into the environment. The cytotoxicity of SMZ relies mainly on arylhydroxylamine metabolites (S-NOH) of SMZ and it is associated with the production of reactive oxygen species (ROS). There is limited information about the toxic potential of SMZ at the cellular and molecular levels, especially in aquatic and/or non-target organisms. In the present study, the red swamp crayfish (Procambarus clarkii), being tolerant to extreme environmental conditions and resistant to disease, was used as a model organism to profile the molecula…
Improved insulin sensitivity and secretion in prediabetic patients with adrenal insufficiency on dual-release hydrocortisone treatment: a 36-month re…
2018
OBJECTIVE Dual-release hydrocortisone (DR-HC) provides physiological cortisol exposure, leading to an improvement of anthropometric and metabolic parameters. The aim of the study was to evaluate the effects of DR-HC on insulin secretion and sensitivity and cardiometabolic risk, indirectly expressed by the visceral adiposity index (VAI). DESIGN AND PATIENTS Retrospective analysis of 49 patients, 13 with primary and 36 with secondary adrenal insufficiency (AI), respectively, on conventional glucocorticoid treatment at baseline and switched to DR-HC for 36 months. Overall, 24 patients had AI-pre-diabetes (impaired fasting glucose, impaired glucose tolerance and the combination), and 25 had AI-…
Screening sierologico per Leishmania infantum su donatori di sangue e HIV+ asintomatici residenti in area endemica [Serological screening for Leishma…
2008
Visceral leishmaniasis (VL) is endemic in Sicily (48 new cases in 2004, of which nine were in Agrigento). In southern Europe between 25-70 per cent of adult VL cases are related to HIV infection. The HIV cases have a high risk (1.5-9%) of developing VL either as a new infection or as the revival of a latent infection. We therefore carried out serologic screening to detect antibodies against L. infantum by IFAT in 1449 blood donors in Agrigento and the surrounding area (May-December 2005) and in 120 HIV+ in western Sicily, all of whom were asymptomatic and had no history of VL. L. DNA was assessed by nested PCR in blood samples of some seropositive donors. Of the 1449 blood donors, 11 (0.75%…
Bone mineral density and bone turnover in Romanian children and young adults with classical 21-hydroxylase deficiency are influenced by glucocorticoi…
2009
Summary Objective It remains controversial if glucocorticoid replacement therapy impairs bone mineral density (BMD) in young patients with 21-hydroxylase deficiency. We aimed to analyze the impact of treatment variables, phenotype and genotype on BMD and bone metabolism in these patients. Design Cross-sectional study. Measurements Twenty-eight Caucasian patients with classical 21-hydroxylase deficiency (5–39 years). Clinical parameters, hormonal status, osteocalcin (OC), C-terminal telopeptide of type I collagen (CTX), genotype and lumbar BMD (Z-scores) were assessed. Cumulative and mean hydrocortisone equivalent doses were calculated for the entire treatment period. Results Patients wi…
